Pharmacists constitute a crucial component of the healthcare system, significantly influencing the provision of medication services and ensuring patient safety. This study aims to understand the characteristics and risk factors for complaints against pharmacists through Health and Disability Commissioner (HDC) published decisions. This study adopts a retrospective, qualitative approach. An inductive content analysis technique was used to analyze 37 complaints against pharmacists published decisions from the New Zealand Health and Disability Commissioner website to investigate a range of underlying risk factors contributing to the occurrence of complaints against pharmacists. A set of 20 categories of risk factors emerged through the content analysis and were subsequently grouped into five overarching themes: pharmacist individual factors, organizational factors, system factors, medication-specific factors, and external environmental factors. The findings of this study provide valuable insights that expand the understanding of risk management in pharmacist practice, serving as a valuable resource for regulatory bodies, policymakers, educators, and practitioners. It is recommended not only to focus solely on individual pharmacists but also to consider integrating their environment and individual behaviors to proactively address situations prone to errors and subsequent complaints.
