Section I: Historical Foundations of Public Health
South Asian public health evolved from colonial disease control systems to comprehensive national frameworks, with the Primary Health Care approach serving as a pivotal but incompletely implemented model.
1
Colonial Era
British-established public health infrastructure focused on disease control and urban centers
2
Post-Independence
Development of national health policies and integration of traditional medicine
3
Primary Health Care
Alma-Ata Declaration influence and community health worker programs
South Asian public health systems have evolved dramatically from their colonial origins. The journey from colonial disease control measures to comprehensive national health policies represents a significant transformation in how health is conceptualized and delivered across the region. The Primary Health Care approach has served as a historical cornerstone, though implementation remains incomplete in many areas.
Colonial public health systems established an urban-centric, disease-control focused framework with restricted access that shaped modern healthcare inequities across South Asia.
Colonial Legacy in Public Health
Urban Focus
Colonial health infrastructure prioritized urban centers, establishing hospitals and medical colleges primarily in cities, while rural areas received minimal healthcare investment.
Disease Control
Public health efforts centered on controlling communicable diseases that threatened colonial interests, with emphasis on quarantine measures and sanitation in administrative centers.
Limited Access
Healthcare access was highly restricted, with quality services primarily available to colonial administrators and elites, creating foundations for the inequities that persist today.
The British colonial influence established the early framework for public health infrastructure across South Asia. This period created lasting institutional structures and approaches that continued to shape post-independence health systems, particularly the urban-centric nature of healthcare delivery and the emphasis on disease control over health promotion.
Post-Independence Health Evolution
South Asian nations transformed colonial healthcare into national systems through policy frameworks, vertical programs, and community-based approaches.

Bhore Committee (1946)
Landmark report establishing health system vision
National Health Programs
Development of targeted vertical health initiatives
Community Health Workers
Introduction of frontline health workforce
Following independence, South Asian nations began transforming colonial healthcare structures into national health systems. In India, the Bhore Committee recommendations of 1946 laid crucial groundwork for developing a comprehensive health system. This period saw significant efforts to integrate traditional and modern medicine while expanding rural healthcare access through community health worker programs.
Primary Health Care Foundations
Primary Health Care in South Asia was shaped by the 1978 Alma-Ata Declaration, emphasizing comprehensive services, community involvement, and intersectoral approaches, though implementation remains challenging.

Comprehensive Care
Integration of preventive and curative services
Community Participation
Active involvement in health planning and delivery
Intersectoral Collaboration
Health linked with water, sanitation, nutrition, etc.
First Contact Access
Essential services at community level
The 1978 Alma-Ata Declaration profoundly influenced health policy across South Asia, establishing Primary Health Care (PHC) as a cornerstone approach. While these principles have shaped policy documents throughout the region, full implementation of PHC-oriented systems remains an ongoing challenge. Early community health worker programs were pioneering efforts to realize the vision of "Health for All."
Traditional Medicine Integration
Traditional healing systems like Ayurveda and Yoga remain integral to South Asian healthcare, with ongoing efforts to integrate these culturally accepted practices into formal medical systems.
South Asia's rich heritage of traditional healing systems—Ayurveda, Yoga, Unani, Siddha, and Homeopathy (collectively AYUSH in India)—continues to play an important role in healthcare delivery. Integration efforts have aimed to bring these practices into formal healthcare systems while preserving their cultural importance. These traditional systems enjoy high community acceptance and often provide accessible care where modern facilities are limited.
Section II: Health Systems Structure
South Asian health systems operate on a three-tier model with primary, secondary, and tertiary care levels, characterized by growing private sector influence and high out-of-pocket costs due to limited government funding.
Primary Care
First point of contact for communities through health centers, sub-centers, and community health workers
Secondary Care
Referral facilities providing specialized services at district and sub-district levels
Tertiary Care
Advanced medical care in regional centers and teaching hospitals
Financing
Complex mix of public funding, private payments, and limited insurance coverage
Health systems across South Asia generally follow a three-tier structure with distinct roles for primary, secondary, and tertiary care facilities. These systems face significant challenges in balancing public and private sector roles. With limited government health expenditure, most countries have seen growing private sector dominance, resulting in high out-of-pocket expenses for citizens.
Current PHC Structure
South Asian countries have established three-tier primary healthcare systems with defined roles, though implementation quality varies significantly across regions.

Community Level
Health workers providing outreach services
Primary Facilities
First contact care in local health centers
Referral Facilities
Secondary services for more complex needs
South Asian countries have established well-defined government primary healthcare structures at the community level. These systems typically involve community health workers providing outreach services, primary facilities serving as the first point of contact, and secondary referral facilities for more complex cases. While the structure appears robust on paper, implementation quality varies significantly across and within countries.
India's Health System Structure
India features a comprehensive three-tier healthcare system with community-level Health and Wellness Centers as the foundation, supported by primary, secondary, and tertiary care facilities forming a complete referral network.

Tertiary Care
Medical colleges and specialized hospitals
Secondary Care
District hospitals and Community Health Centers
Primary Care
Primary Health Centers and Sub-centers
Community Level
Health and Wellness Centers and ASHAs
India operates a three-tier healthcare system with newly established Health and Wellness Centers (HWCs) forming the foundation. These are supported by sub-centers and Primary Health Centers (PHCs) at the village level, Community Health Centers (CHCs) at the block level, and district and specialized hospitals at higher levels. This structure aims to provide comprehensive care with appropriate referral pathways throughout the system.
Bangladesh's Health System
Bangladesh has built a comprehensive healthcare network with 30,000+ Community Clinics forming the foundation, supported by multi-tiered facilities extending from local unions to specialized district hospitals.
Community Clinics

Upazila Complexes
Sub-district health facilities
District Hospitals
Specialized care facilities
Bangladesh has developed an extensive primary healthcare network centered around more than 30,000 Community Clinics nationwide. These are complemented by Union Health and Family Welfare Centers at the union level, Upazila Health Complexes at the sub-district level, and district hospitals and specialized facilities for advanced care. This system represents one of the most comprehensive community-based approaches in the region.
Pakistan's Health System
Pakistan employs a four-tiered healthcare structure from community-based Lady Health Workers to specialized District Hospitals, providing varying levels of care across the country's provinces.
Lady Health Workers
Cornerstone of Pakistan's community health outreach, providing door-to-door preventive and basic curative services to rural and urban slum populations
Basic Health Units
Primary care facilities serving approximately 10,000-25,000 people each, offering essential health services including maternal and child health care
Rural Health Centers
Secondary facilities covering 25,000-50,000 population with expanded services including basic laboratory diagnostics and limited inpatient care
District Hospitals
Comprehensive facilities at tehsil and district levels providing specialized services and serving as major referral centers
Pakistan's health system is anchored by its pioneering Lady Health Workers program, which brings basic health services directly to communities. The formal facility network includes Basic Health Units (BHUs), Rural Health Centers (RHCs), and Tehsil and District Headquarters Hospitals providing increasingly specialized care. Coverage and quality vary significantly across provinces.
Nepal's Health System
A geographically-adapted healthcare model built on a foundation of community volunteers, supported by a tiered network of institutional facilities providing increasingly specialized care.
Female Community Health Volunteers
Nepal's network of over 50,000 FCHVs forms the foundation of rural healthcare delivery, providing health education, basic treatments, and crucial linkages between communities and formal healthcare facilities.
Health Posts
These facilities serve as the first institutional contact point in the healthcare system, offering preventive and basic curative services to roughly 5,000 people each, often in challenging geographic locations.
Primary Health Care Centers
PHCCs provide more comprehensive services including some laboratory testing and are staffed by medical officers, serving as the first referral point for health posts in their catchment area.
Nepal's health system has adapted to the country's challenging mountain geography through an extensive network of Female Community Health Volunteers who reach even the most remote communities. The formal system includes Health Posts, Primary Health Care Centers, and District and regional hospitals, with service availability significantly affected by geographical accessibility.
Sri Lanka's Health System
Sri Lanka's public health system features a tiered structure of care facilities that has achieved impressive health outcomes despite resource constraints.
Medical Officer of Health Areas
Geographic regions under the supervision of a Medical Officer of Health who coordinates preventive health services including maternal and child health, immunization, and disease control.
Primary Medical Care Units
Entry-point facilities providing outpatient services, staffed by medical officers and supporting staff to deliver essential healthcare services to local communities.
Divisional and District Hospitals
Secondary care facilities offering inpatient services, emergency care, and specialized outpatient clinics, forming the backbone of Sri Lanka's highly regarded public health system.
Sri Lanka has achieved remarkable health outcomes through its well-organized public health system. The country divides health administration into Medical Officer of Health areas with Primary Medical Care Units providing entry-point services. This is complemented by Divisional Hospitals and District General Hospitals offering increasingly specialized care. Sri Lanka's system is often cited as a model for achieving good health outcomes with limited resources.
Public-Private Healthcare Mix
Private healthcare providers now dominate outpatient care delivery across South Asia, accounting for nearly 60% of services amid public sector constraints, contributing to high out-of-pocket costs.
Across South Asia, there has been a dramatic shift toward private sector dominance in healthcare delivery. Private providers now account for the majority of outpatient care in most countries. This shift has occurred amid significant public sector resource constraints, contributing to high out-of-pocket expenditures for patients. Health insurance coverage remains limited across the region, leaving many vulnerable to catastrophic health expenses.
Health Financing Challenges
South Asian countries invest significantly less in healthcare (3.2% of GDP) than the global average (8.2%), while citizens face extremely high out-of-pocket expenses (50-74%), creating financial hardship and healthcare access barriers.
Health expenditure across South Asia has declined relative to GDP from 2000-2006, currently averaging around 3.2% compared to the global average of 8.2%. This underfunding creates severe constraints on public health systems. High out-of-pocket expenses—often exceeding 60% of total health expenditure—place significant financial burdens on households, with limited social health protection schemes available to mitigate these costs.
Section III: Key Public Health Challenges
South Asia faces a complex health transition with dual disease burdens, demographic shifts, and persistent maternal-child health concerns, creating multifaceted challenges for regional healthcare systems.
Demographic Transition
Rapid population growth combined with urbanization and an emerging aging population creating complex service demands
Disease Burden
Double burden of persistent infectious diseases alongside rising non-communicable disease epidemic
Maternal and Child Health
Despite improvements, maternal and neonatal mortality remain challenging public health priorities
Antimicrobial Resistance
Growing threat due to antibiotic misuse, weak regulation, and limited surveillance systems
South Asia faces a complex epidemiological transition characterized by the persistence of traditional public health challenges alongside emerging threats. This section examines the demographic and epidemiologic transitions creating a double burden of disease, with particular attention to maternal and child health indicators that remain priority concerns throughout the region.
Demographic Profile
South Asia represents 22% of global population with a youth-dominated demographic structure, though an aging population is emerging alongside rapid urbanization, creating complex healthcare demands.
South Asia's demographic profile creates unique public health challenges, with a population of 1.74 billion representing 22% of global population. The region is experiencing rapid urbanization, creating dense population centers with specific health needs. A notable "youth bulge" dominates the population structure, though an aging population is also emerging, particularly in Sri Lanka. These demographic patterns require health systems to simultaneously address youth needs while preparing for age-related conditions.
Double Burden of Disease
South Asia faces simultaneous challenges from infectious diseases and a rising tide of non-communicable conditions, creating complex demands on healthcare systems that must also address mental health issues and injuries.
Communicable Diseases
Persistent TB, malaria, neglected tropical diseases
Non-Communicable Diseases
Rising cardiovascular disease, diabetes, cancer
Mental Health
Depression, anxiety, substance use disorders
Injuries
Road accidents, occupational injuries, violence
South Asia experiences a classic "double burden" of disease, characterized by persistent communicable diseases alongside a rapidly rising epidemic of non-communicable diseases. This creates complex demands on health systems designed primarily for acute infectious disease management. Mental health challenges and injuries from accidents and violence further complicate the disease burden, requiring health systems to develop more comprehensive approaches to address these varied health needs simultaneously.
Communicable Disease Burden
South Asia faces major infectious disease challenges, with the world's highest tuberculosis burden, significant vector-borne diseases like malaria and dengue, and growing antimicrobial resistance concerns.
South Asia continues to face significant communicable disease challenges, carrying the highest global burden of tuberculosis with India alone accounting for approximately one-fourth of global cases. HIV/AIDS presents as concentrated epidemics in high-risk populations, while endemic vector-borne diseases like malaria and dengue remain prevalent. Antimicrobial resistance has emerged as a critical concern across the region, exacerbated by weak antibiotic regulation and inappropriate prescribing practices.
Non-communicable Disease Transition
South Asia is experiencing a significant shift toward non-communicable diseases, with NCDs now causing the majority of deaths. The region faces high rates of diabetes, hypertension, and late-stage cancer diagnoses driven by urbanization and lifestyle changes.

Late Diagnosis
Cancer cases detected at advanced stages
Non-communicable diseases (NCDs) have become the leading cause of morbidity and mortality across South Asia, with cardiovascular diseases, diabetes, chronic respiratory conditions, and cancers causing the majority of deaths. The region has the largest diabetic population globally, with lifestyle changes, urbanization, and dietary transitions driving this epidemic. Limited screening programs mean cancer is often diagnosed at advanced stages, significantly reducing survival rates.
Maternal and Child Health
South Asia has seen significant reductions in maternal mortality (64%) and neonatal mortality (51%) from 2000-2020, though challenges persist in rural areas and with issues like malnutrition and adolescent health.
Despite significant improvements over the past two decades, maternal and child health remains a critical concern across South Asia. Maternal mortality has declined but remains high in many areas, particularly in rural and underserved regions. Neonatal mortality presents a particular challenge, accounting for a significant proportion of under-five deaths. Malnutrition and stunting among children continue to be prevalent, while adolescent health needs often receive insufficient attention.
Nutrition Challenges
South Asia faces a complex nutritional landscape with high childhood stunting, widespread micronutrient deficiencies, persistent food insecurity, and an emerging urban obesity crisis alongside rural undernutrition.
Childhood Stunting
Over 38% of children under 5 in South Asia suffer from stunting due to chronic malnutrition, with lifelong consequences for physical and cognitive development
Micronutrient Deficiencies
Iron, vitamin A, iodine, and zinc deficiencies are widespread, contributing to anemia, compromised immunity, and developmental challenges
Food Insecurity
Despite agricultural production increases, unequal food distribution and poverty lead to persistent food insecurity for millions of households
Urban Obesity
A growing nutrition transition is creating dual challenges with obesity emerging in urban settings while undernutrition persists in rural areas
Nutrition presents complex challenges across South Asia, with high rates of childhood stunting affecting over one-third of children under five years. Micronutrient deficiencies remain widespread, contributing to anemia and other conditions. Food insecurity affects millions despite agricultural productivity increases. Meanwhile, an emerging nutrition transition is creating a dual burden, with obesity becoming more prevalent in urban areas while undernutrition persists elsewhere.
Mental Health Burden
South Asia faces a critical mental health crisis with treatment gaps exceeding 85% and severe shortages of professionals (less than 1 per 100,000 population), while stigma and limited infrastructure prevent effective care delivery.
Treatment Gap
The difference between those needing treatment and those receiving it exceeds 85% across South Asia. Most mental health conditions go undiagnosed and untreated due to limited services and stigma.
Primary health systems generally lack mental health integration, with specialized care concentrated in urban centers. This creates vast disparities in access between rural and urban populations.
Professional Resources
South Asia faces a severe shortage of mental health professionals:
  • Psychiatrists: 0.2 per 100,000 (vs. 10+ in high-income countries)
  • Psychologists: 0.1 per 100,000
  • Social workers: 0.3 per 100,000
This workforce gap makes comprehensive care impossible for most of the population.
Mental health represents a growing but often neglected public health concern across South Asia. Access to mental healthcare is severely limited, with enormous treatment gaps exceeding 85% in most countries. Stigma continues to prevent many from seeking help, while suicide rates are rising, particularly among younger populations. The professional resource shortage is acute, with the number of mental health specialists far below recommended levels.
Environmental Health Concerns
South Asia faces critical environmental health challenges including dangerous air pollution, compromised water quality, climate change vulnerabilities, and inadequate occupational safety standards.
Environmental health challenges significantly impact public health across South Asia. Air pollution in major cities consistently exceeds safe levels, contributing to respiratory diseases and premature deaths. Water quality remains compromised in many areas, with inadequate sanitation infrastructure exacerbating waterborne diseases. The region's high vulnerability to climate change effects—including flooding, heat waves, and changing disease patterns—creates emerging health threats, while occupational safety standards remain inadequate in many industries.
Section IV: Social Determinants of Health
Social factors including poverty, gender, geography, and education significantly influence health outcomes in South Asia, often creating systematic disparities that require addressing root causes rather than symptoms alone.
Poverty
Economic barriers to healthcare access and quality nutrition
Gender
Disparities in healthcare access and health outcomes
Geography
Rural-urban divides in healthcare resources
Education
Health literacy and awareness impacts
In South Asia, health outcomes are profoundly shaped by social and economic factors beyond the healthcare system. This section examines how poverty, gender inequity, rural-urban disparities, and education levels create systematic differences in health access and outcomes. Understanding these social determinants is essential for developing effective public health interventions that address root causes rather than just treating resulting conditions.
Poverty as Health Determinant
Poverty in South Asia creates a devastating cycle where limited resources restrict healthcare access, while health expenses simultaneously drive families deeper into poverty, resulting in significantly worse health outcomes for economically disadvantaged populations.
Catastrophic Health Expenditures
Over 60 million people in South Asia are pushed into poverty annually due to out-of-pocket healthcare costs, creating a vicious cycle where illness leads to deeper poverty.
Social Gradient
Health outcomes worsen progressively with decreasing socioeconomic status, with the poorest quintile experiencing mortality rates 2-3 times higher than the wealthiest.
Access Barriers
Economic constraints limit healthcare utilization, with the poorest often unable to afford transportation costs, medication expenses, and lost wages from seeking care.
South Asia's high concentration of global poverty—housing two-thirds of the global population living on less than $1 per day—creates profound health implications. The relationship between poverty and poor health outcomes forms a bidirectional relationship: poverty restricts access to healthcare, nutrition, and sanitation, while illness often drives families deeper into poverty through catastrophic health expenditures and lost productivity.
Gender inequalities in South Asia create significant health disparities, affecting women's access to care, reproductive autonomy, and vulnerability to violence.
Gender and Health
Reproductive Health
Women face significant challenges in accessing reproductive healthcare services, with sociocultural factors often limiting decision-making autonomy regarding family planning and maternal care.
Despite policy improvements, maternal mortality remains elevated due to delays in seeking care, reaching facilities, and receiving quality treatment—all influenced by gender norms and women's status.
Gender-Based Violence
Gender-based violence represents a serious public health concern across South Asia, with significant physical and mental health consequences for women and girls.
Health systems often fail to adequately identify, document, or address violence against women, lacking both protocols and trained providers to respond effectively to survivors' needs.
Gender disparities significantly impact health outcomes across South Asia, with women often facing greater barriers to healthcare access due to limited mobility, decision-making power, and financial resources. Women's reproductive health remains a critical concern, with autonomy over family planning decisions often restricted by sociocultural factors. Meanwhile, gender-based violence represents a widespread but underaddressed health concern, while gender imbalances in the health workforce affect service delivery.
Rural-Urban Health Divide
Rural areas in South Asia have significantly fewer healthcare resources than urban centers, with up to 10 times fewer doctors, nurses, and facilities, compounded by geographical and transportation barriers.
A stark rural-urban divide characterizes healthcare access across South Asia, with health resources heavily concentrated in urban centers. Rural areas face critical shortages of healthcare providers, with doctor-to-population ratios often 10 times lower than in cities. Transportation barriers frequently prevent rural residents from accessing care, with difficult terrain and limited infrastructure creating significant challenges in mountainous regions of Nepal, northern Pakistan, and parts of India.
Education and Health Literacy
Educational attainment—especially for women—significantly impacts health outcomes across South Asia, with health literacy being a critical factor in effective healthcare utilization.

Education Level
Strong correlation with health outcomes
Female Education
Particularly impactful on family health
Health Literacy
Understanding health information and systems
Information Access
Digital and traditional channels
Education levels strongly correlate with health outcomes across South Asia, influencing health-seeking behavior, adherence to medical advice, and preventive practices. Female education has particularly strong impacts on family health, with each additional year of maternal education associated with a 7-9% reduction in child mortality. Health literacy—the ability to obtain, process, and understand basic health information—remains limited in many communities, hampering effective healthcare utilization and self-management of conditions.
Section V: Health as a Right
This section explores how South Asian countries approach health as a fundamental right through constitutional frameworks, universal coverage initiatives, and rights-based policies that prioritize vulnerable populations.
Constitutional Frameworks
Legal foundations for health rights vary across South Asian constitutions, with some explicitly recognizing health as a right while others address it through directive principles or judicial interpretation.
Universal Coverage
Countries have embraced universal health coverage as a goal, implementing various insurance schemes and service expansion programs with varying degrees of comprehensiveness and success.
Rights-Based Approach
A shift toward viewing health through a rights lens emphasizes accountability, participation, non-discrimination, and attention to vulnerable populations in health policy and service delivery.
This section examines health as a fundamental right rather than merely a service, exploring the constitutional and legal frameworks that establish health rights across South Asia. We'll examine the journey toward universal health coverage, highlight innovative programs like India's Ayushman Bharat, and consider how rights-based approaches can address the needs of vulnerable populations.
Constitutional Health Rights
South Asian constitutions vary in their approach to health rights, with Nepal explicitly guaranteeing healthcare as a fundamental right, while India, Bangladesh, and Pakistan rely on judicial interpretation of right to life provisions and directive principles.
Indian Constitution
While not explicitly recognizing health as a fundamental right, Article 21 (right to life) has been judicially interpreted to include the right to health. Directive Principles in Articles 39, 42, and 47 provide additional basis for health rights.
Nepal's Constitution
Article 35 explicitly guarantees the right to healthcare as a fundamental right, stating "Every citizen shall have the right to free basic health services from the State, and no one shall be deprived of emergency health services."
Bangladesh and Pakistan
Both constitutions address health through directive principles rather than fundamental rights, though judicial activism has expanded interpretations to include certain health rights through right to life provisions.
Constitutional provisions for health rights vary significantly across South Asia. In recent decades, judicial interpretations have progressively expanded health rights beyond literal constitutional text. Notable court cases have established government responsibilities for emergency care, essential medicines, and environmental health protections. Despite these advances, implementation gaps persist between legally recognized rights and their practical realization.
Universal Health Coverage Journey
South Asian countries show varied progress toward Universal Health Coverage, with Sri Lanka leading in both service coverage and financial protection, while other nations face challenges with coverage gaps and financial barriers, particularly for marginalized populations.
The journey toward Universal Health Coverage (UHC) reflects varying levels of progress across South Asia. Sri Lanka leads with the most comprehensive coverage and financial protection mechanisms, while other countries show more moderate advances. Service coverage metrics measure the proportion of essential services available to populations, while financial protection indicators assess whether healthcare costs drive households into poverty. Equity in access remains a significant concern, with marginalized communities often experiencing the largest coverage gaps.
India's Ayushman Bharat
A two-pronged approach to universal health coverage in India through the world's largest health insurance scheme serving 500+ million citizens and a network of comprehensive primary care facilities.
Health Insurance Component (PMJAY)
Provides coverage for 500+ million citizens (bottom 40% of population) with ₹5 lakh (approximately $6,700) annual coverage per family for secondary and tertiary care, making it the world's largest health insurance scheme.
Health and Wellness Centers
Aims to transform 150,000 Sub-Centers and Primary Health Centers into Health and Wellness Centers delivering comprehensive primary care, expanding services from 8 to 12 essential health service packages.
Implementation Progress
Over 125 million e-cards issued and 20+ million hospitalizations covered under insurance component, while approximately 75,000 HWCs have been operationalized, significantly expanding primary care access.
Launched in 2018, India's Ayushman Bharat program represents an ambitious approach to universal health coverage through two complementary components: a massive health insurance scheme providing secondary and tertiary care coverage to over 500 million citizens, and a primary care strengthening initiative converting facilities into comprehensive Health and Wellness Centers. Implementation challenges include provider participation, quality control, and sustainable financing, but early successes show promising improvements in healthcare access.
Health Rights of Vulnerable Populations
Across South Asia, four key vulnerable groups—tribal communities, persons with disabilities, the elderly, and migrants—face unique barriers to healthcare access, requiring targeted interventions to address their specific needs and ensure health equity.
Tribal and Indigenous Communities
Face multiple barriers including geographical isolation, cultural differences, and historical marginalization, resulting in significantly worse health indicators than general populations
Persons with Disabilities
Often experience healthcare discrimination, physical accessibility challenges, and communication barriers when seeking services, with limited accommodation in mainstream health systems
Elderly Population
Rapidly growing demographic with specific healthcare needs including chronic disease management and long-term care, currently underserved by systems designed for acute care
Migrant Populations
Internal and international migrants face documentation barriers, continuity of care challenges, and often work in hazardous conditions with limited health protections
Vulnerable populations across South Asia face distinct challenges in realizing their health rights. Tribal and indigenous communities experience geographical isolation and cultural barriers to care. Persons with disabilities encounter physical accessibility issues and communication challenges. The growing elderly population has specialized needs often unmet by existing systems. Migrant populations frequently fall through coverage gaps due to documentation requirements and jurisdictional issues.
Section VI: Health System Performance
This section evaluates four critical dimensions of health systems: quality of care delivery, healthcare workforce distribution, access to essential medicines, and health information systems infrastructure.

Quality of Care
Assessment of healthcare delivery quality and safety
Health Workforce
Availability and distribution of healthcare providers
Essential Medicines
Access to necessary pharmaceutical products
Information Systems
Data collection and utilization for decision-making
Assessing health system performance provides crucial insights into how effectively services are delivered. This section examines quality of care standards, health workforce distribution challenges, essential medicines access, and health information systems across South Asia. Understanding these operational aspects of healthcare delivery is essential for identifying targeted improvement strategies and ensuring that system design translates to actual health benefits for populations.
PHC Performance Assessment
Primary health care services show strong performance in traditional areas like immunization and TB treatment, but significant gaps exist in non-communicable disease management, with additional concerns regarding quality indicators and patient satisfaction.
Primary Health Care (PHC) performance assessment reveals significant variations across service areas and countries. Traditional maternal and child health services generally show higher coverage rates than non-communicable disease management. Quality indicators beyond coverage—including diagnostic accuracy, treatment appropriateness, and continuity of care—often show concerning gaps. Patient satisfaction measures indicate widespread dissatisfaction with waiting times, provider attitudes, and out-of-pocket costs, though appreciation for community-based services is generally high.
Health Workforce Challenges
South Asia suffers from critical shortages of healthcare professionals, with fewer doctors and nurses than WHO recommendations. Most healthcare workers are concentrated in urban areas despite the majority of the population living rurally, while significant numbers emigrate annually.

South Asia faces severe health workforce challenges, with doctor-population ratios falling below WHO recommendations across most countries. The geographical maldistribution of providers creates particular shortages in rural and remote areas, where approximately 65% of the population resides but only 25% of doctors practice. Training capacity limitations restrict the pipeline of new professionals, while brain drain of health professionals to high-income countries further depletes the available workforce.
Medical Education and Training
South Asia experiences rapid growth in medical education institutions alongside quality variations and training gaps that emphasize specialization over primary care, contributing to workforce imbalances that don't effectively address population health needs.
Medical Education Landscape
South Asia has seen rapid expansion of medical education institutions, with a particularly dramatic increase in private medical colleges. India alone has over 520 medical colleges, producing approximately 80,000 MBBS graduates annually.
However, quality concerns persist across the region, with significant variations in infrastructure, faculty qualifications, and clinical exposure between prestigious institutions and lower-tier facilities.
Training Challenges
The current education system emphasizes:
  • Specialization over primary care competencies
  • Hospital-based over community-oriented training
  • Curative rather than preventive approaches
  • Urban practice preparation instead of rural readiness
These educational priorities contribute to workforce maldistribution and gaps in primary healthcare delivery.
Medical education across South Asia has expanded significantly, with substantial growth in private institutions. Quality standardization remains challenging, with accreditation systems often struggling to ensure consistent standards. Continuing education opportunities for practicing professionals are limited, particularly in rural areas. The educational emphasis on specialization rather than primary care orientation contributes to workforce imbalances that fail to address population health needs effectively.
Essential Medicines Access
South Asian countries have established essential medicines policies, but face significant challenges in implementation, supply chain management, and quality assurance, despite the region's strong generic pharmaceutical production capacity.
Essential Medicines Lists
All South Asian countries have established national essential medicines lists defining priority medications that should be available in public facilities, though actual availability often falls short of policy requirements.
Generic Medicines Policies
Policies promoting generic prescription and substitution exist across the region, but implementation remains inconsistent. India has emerged as a global pharmaceutical manufacturing hub, producing affordable generics.
Supply Chain Challenges
Inventory management systems are often inadequate, with frequent stock-outs of essential medications. Last-mile delivery to remote facilities presents particular challenges across the region.
Access to essential medicines remains challenging across South Asia despite policy frameworks supporting availability. Supply chain management issues frequently lead to stock-outs, particularly in remote facilities. While the region (especially India) produces many affordable generic medications, patients often pay for medicines out-of-pocket due to limited public sector availability. Quality concerns persist, with inadequate regulatory oversight of manufacturing and distribution in some areas.
Health Information Systems
South Asian health information systems are transitioning to digital formats despite infrastructure challenges. Current issues include data quality concerns, fragmented reporting systems, and limited utilization of collected information for decision-making.
Data Collection
Digital and paper-based systems
Information Storage
Centralized and local databases
Analysis
Converting data to usable insights
Decision Support
Evidence-informed policy and practice
Health information systems across South Asia are undergoing digital transformation, though progress varies considerably. Electronic health records implementation faces infrastructure challenges, particularly in rural areas with limited connectivity and power supply. Health surveillance capabilities have improved, especially for notifiable diseases, but data quality and utilization for decision-making remain problematic. Fragmentation between various health programs creates parallel reporting systems that burden providers and limit comprehensive analysis.
Section VII: Current Innovations and Reforms
South Asia is pioneering healthcare innovations across four key areas: digital health, community participation, financial solutions, and cross-sector partnerships.
South Asia has become a vibrant laboratory for healthcare innovation, developing solutions adapted to resource-constrained settings.
