Informal Providers—Ground Realities in South Asian Association for Regional Cooperation Nations: Toward Better Cancer Primary Care: A Narrative Review

South Asian Association for Regional Cooperation (SAARC) nations are a group of eight countries with low to medium Human Development Index values. They lack trained human resources in primary health care to achieve the WHO-stated goal of Universal Health Coverage. An unregulated service sector of informal health care providers (IPs) has been serving these underserved communities. The aim is to summarize the role of IPs in primary cancer care, compare quality with formal providers, quantify distribution in urban and rural settings, and present the socioeconomic milieu that sustains their existence. METHODS: A narrative review of the published literature in English from January 2000 to December 2021 was performed using MeSH Terms Informal Health Care Provider/Informal Provider and Primary Health Care across databases such as Medline (PubMed), Google Scholar, and Cochrane database of systematic reviews, as well as World Bank, Center for Global Development, American Economic Review, Journal Storage, and Web of Science. In addition, citation lists from the primary articles, gray literature in English, and policy blogs were included. We present a descriptive overview of our findings as applicable to SAARC. RESULTS: IPs across the rural landscape often comprise more than 75% of primary caregivers. They provide accessible and affordable, but often substandard quality of care. However, their network would be suitable for prompt cancer referrals. Care delivery and accountability correlate with prevalent standards of formal health care. CONCLUSION: Acknowledgment and upskilling of IPs could be a cost-effective bridge toward universal health coverage and early cancer diagnosis in SAARC nations, whereas state capacity for training formal health care providers is ramped up simultaneously. This must be achieved without compromising investment in the critical resource of qualified doctors and allied health professionals who form the core of the rural public primary health care system.
