Beyond Task Delegation: Progressive Negotiated Embedding of a Physician Associate in Rural Primary Care—A Longitudinal Qualitative Case Study from India

Abstract Background Physician Associates (PAs) in India have historically worked mainly in hospital specialties. National education reform now places greater emphasis on generalist and community-oriented preparation, but little is known about how an unfamiliar PA role becomes integrated into rural primary care. We examined how one newly introduced PA role was negotiated and embedded over time. Methods We conducted a longitudinal embedded single-case study in a rural primary-care service in Kerala, India. Purposive sampling included the deployed PA, three medical officers, four other healthcare/community stakeholders and six patients. Data comprised 14 individual interviews conducted in English, one Malayalam patient focus-group discussion, and 126 active-deployment reflective records. Reflexive thematic analysis was combined with longitudinal within-case and cross-source comparison. Results Participants described integration as progressive negotiated embedding rather than simple task delegation. Four linked themes characterised the process: (1) the unfamiliar role became locally legible as staff observed enacted capability; (2) wider but bounded entrustment developed alongside observed performance, while prescribing and final clinical decisions remained physician-linked; (3) the role broadened from task support into boundary-spanning coordination across physicians, nursing, pharmacy, referrals, outreach and organisational work; and (4) repeated contact was associated with growing trust and routine reliance, while formal institutionalisation lagged behind. Participants perceived smoother flow and redistributed workload, but these were not objectively measured. Role flexibility also created risks of overextension. Conclusions In this case, the PA role became locally understood through observed work and progressively incorporated through bounded physician-linked entrustment and coordination across service interfaces. For comparable settings, the findings suggest explicit physician-linked accountability, supervised opportunities for capability to become visible, clear role boundaries, recognition of coordination work, and early planning for continuity and governance. The findings do not establish doctor substitution, independent practice, clinical effectiveness or scalability.
