Socioecological Factors Linked With Pharmaceutical Incentive-Driven Prescribing In Pakistan, Muhammad Naveed Noor, Afifah Rahman-Shepherd, Amna Rehana Siddiqui, Wafa Aftab, Sadia Shakoor, Rumina Hasan, Mishal Khan

Department of Pathology and Laboratory Medicine

Pharmaceutical marketing through financial incentivisation to general practitioners (GPs) is a poorly studied health system problem in Pakistan. Pharmaceutical incentivisation is seen to be distorting GPs prescribing behaviour that can compromise the health and well-being of patients. We draw on a conceptual framework outlined in the ecological system theory to identify multiple factors linked with pharmaceutical incentivisation to GPs in Pakistan. We conducted qualitative interviews with 28 policy actors to seek their views on the health system dynamics, how they sustain pharmaceutical incentivisation and their effect on the quality of care. Our analysis revealed four interlinked factors operating at different …
