Abstract – A key component of robust health systems that can successfully combat pandemics and epidemics is primary health care (PHC). Along with past outbreaks like Ebola, SARS, and influenza, the COVID-19 pandemic has brought attention to how important primary care is for early detection, continuity of critical services, and fair access to healthcare. The global evidence on how PHC systems can be improved to improve preparedness and response to epidemics and pandemics is compiled in this scoping review. Peer-reviewed literature from 2000 to 2025 was examined using recognized scoping review techniques in order to pinpoint important tactics, difficulties, and policy ramifications. The results show that resilient PHC depends on workforce capacity building, integrated surveillance, community involvement, digital health innovation, governance, and financing mechanisms. The review highlights the necessity of methodically incorporating emergency preparedness into regular PHC operations and offers evidence-based policy recommendations to improve the resilience of the health system.

1. INTRODUCTION

   In the context of epidemic and pandemic risk, primary health care (PHC) is increasingly acknowledged as a crucial factor in determining the resilience of the health system. PHC serves as the cornerstone for the delivery of health services at the population level. PHC incorporates community-based, preventive, curative, rehabilitative, and promotional services into decentralized service networks that connect people, households, and public health facilities. Epidemic shocks interfere with routine care, limit the availability of resources, change how people seek care, and worsen already-existing disparities in outcomes and access. Systems with a strong PHC orientation exhibit greater absorptive and adaptive capacity, as evidenced by comparative data from COVID- 19, Ebola, SARS, and influenza outbreaks. This is demonstrated by improved community-level detection and referral, more effective engagement with high-risk and socially marginalized populations, and sustained coverage of essential services. PHC supports culturally situated risk communication, decentralized triage, continuity of chronic illness and maternal-child health services, and surveillance-linked screening in such situations. On the other hand, during medical emergencies, service disruption and indirect mortality are more common in fragmented and hospital-centric systems. In many low- and middle-income settings, PHC's ability to contribute to preparedness is still hampered by enduring issues such as a lack of workers, unequal funding, unstable supply chains, and limited digital interoperability. Therefore, a thorough synthesis of PHC-centered strategies is necessary to elucidate how PHC enhances epidemic response and to guide policy directions for integrating preparedness into regular service delivery architectures [59].

2. CONCEPTUAL FRAMEWORK: PRIMARY HEALTH CARE AND HEALTH SYSTEM RESILIENCE

   Resilience in health systems is generally defined as the ability of a health system to prepare for, absorb, adapt to, and recover from disturbances while continuing essential system functions. In terms of resilience properties such as adaptability, integrated or holistic attention, redundancy, and learning or improvement, PHC acts as one of the organizational domains that facilitate its operationalization. PHC structures facilitate decentralized decision-making, task-shifting during personnel shortages, integrating preventive and curative services, and one-way or two-way communication between communities and health officials. In outbreak situations, PHC facilities serve as surveillance points, initial assessment points, referral points, and continued care points for high- risk population segments. The trust component of PHC service delivery strengthens active involvement of communities, aids in

   better adherence to public health practices, and works well in countering misinformation. PHC linkage with health information technology increases capacity for syndromic surveillance, early warning, and risk stratification of patient care, and redundancy concepts for personnel and services during outbreak periods improve flexibility in operation. At a more conceptual level, it could be said that PHC emerges not merely as a level of service delivery, but rather as a dynamic institutional response, which integrates preparedness, legitimacy, and a capacity for learning within a broader health system framework.

3. OBJECTIVES OF THE REVIEW

   The aims of this review have been honed further, taking into account the expanded focus of analysis. First, the review charts international evidence regarding PHC strategy approaches to pandemic preparedness, response, and recovery plans. Secondly, it assesses outcomes of PHC approaches regarding service continuity, strengthened surveillance, and protection of the workforce, along with equity of access, digital health, and engagement. Thirdly, the review explores PHC-enabling factors and constraints, covering PHC governance, PHC finances, availability of reliable supply chains, and social trust approaches. Fourthly, it points out the residua of weak cost-effectiveness assessment, a paucity of longitudinal evidence, and under-representation of community-led and gender-responsive PHC research. Finally, the research endeavors to secure policy-relevant findings useful for prioritizing and mainstreaming PHC-resilience approaches at the country and local levels [14-17].

4. METHODOLOGY

   This review adopted the Arksey and OMalley model with modifications by Levac et al., following PRISMA-ScR guidelines for reporting. In this study, searches were performed on four databases: PubMed, Scopus, Web of Science, and Google Scholar. These searches were done for a literature span between 2000 and 2025 with a specific combination of keywords focusing on PHC, resilience, readiness, response during an outbreak, and management during a pandemic. For filtering, a two-step procedure, title and abstract stage followed by full texts review, according to specific criteria for PHC-related epidemic/pandemic programs, took place. Relevant materials included were peer-reviewed publications on empirical, mixed-methods studies; implementation, and policy analyses on PHC-related research and programs in contexts on catastrophic pandemics. Extraction took note of setting factors, type of interventions, processes, indicators for outcomes, and setting enablers/conversely, factors for PHC programs during pandemics. This review adopted a narrative thematic analysis design for synthesis in a manner that facilitated thematic comparisons across varied settings in pandemic contexts despite anticipated heterogeneity for an observed Scoping reviews baseline of study evidence validity [18-21].

5. RESULTS AND DISCUSSION

   This section includes more detailed analytical interpretations and stronger connections to theoretical constructs of resilience. Results show that PHC-grounded systems were more flexible, had better continuity for key service provision, and were responsive to epidemic dysruptions. An integrated PHC-based Surveillance system was associated with improvemens for earlier case identification, timely referrals, and community-based outbreak control for better outbreak response, with decentralization used to decrease reliance on tertiary care. Readiness among personnel was furthermore established as key to broader system response performancewhen there was specified training, psychosocial support programs, and sufficient protective gear. Participation with community was both protective and facilitative to respond to communication channel improvements for better adherence to public health practices. Telemedicine scale-up efforts, mobile clinical outreach, and strategies for task-sharing helped to sustain non- COVID-19 services with lower indirect mortality. Inequality issues such as supply chain vulnerability, digital division biases, and support finance schemes sometimes constrained PHC efforts for many settings. Taken overall, there is confirming evidence to support that pre-crisis PHC investment remains a predictor for resilience outcomes during crisis durations [22-26].

6. POLICY IMPLICATIONS

   Firstly, epidemic preparedness should be formally integrated into regular PHC governance frameworks through established training infrastructure, preparedness planning, and partnerships for surveillance in collaboration with public health authorities. Secondly, financing should transition from emergency grant financing to focused and predictable PHC investment and infrastructure development in architecture and digital health infrastructure. Thirdly, PHC governance should enhance and leverage decentralization and intersectoral frameworks to enable PHC decision-making adapted to contexts. Fourthly, PHC should address equity and priority should be on equity-reforming PHC to ensure that access is not compromised for vulnerable populations in times of emergencies. Finally, learning health system infrastructure and investment in evaluation and feedback could offer radical transformations of episodic responses to emergencies into sustainable institutional solutions [27]-[30].

7. RESEARCH GAPS AND FUTURE DIRECTIONS

   This thematic area now leads into a more general and critical reflection on outstanding issues and current research agendas. There is continuing evidence gap evidence on comparative assessments of PHC-based versus hospitalized preparedness strategies, and on long-term analyses of digital health integration and sustainability outcomes. There is also sparse empirical data on scaling perspectives of gender, disability, immigration, and vulnerability differentials on PHC care accessibility and service utilization and sustainability during epidemics. There is inadequate utilization of implementation science frameworks, which leads to a lack of data on scaling perspectives on transferable strategies and outcomes on system transformations [31-33].

8. CONCLUSION

Resilient Primary Health Care systems are critical for successful epidemic/Pandemic preparedness, response, and recovery efforts. National investments in PHC infrastructure, capability, surveillance integration, and partnerships are found to be stronger in countries with improved ability to sustain core services, reduce Indirect Mortality Rates, and shield vulnerable groups during crises. Incorporating such preparedness activities within core PHC activities, instead of treating them as "specialized" activities during emergencies, is one such strategy for achieving sustainable, adaptive, and equitable health system resilience. It remains paramount that the lessons derived from this review be transformed via sustainable change processes through continued political commitments, sustained investments, and informed change processes [3,7,12,25].
