How to engage healthcare providers in preventing medication waste through individualized prescribing and dispensing: A qualitative study

Background: Medication waste is a threat to healthcare's sustainability. To prevent medication waste in patients' homes, medication quantities prescribed and dispensed to patients could be individualized. Perspectives of healthcare providers on engaging in this strategy however remain unclear.Objective(s): To identify factors influencing healthcare providers in preventing medication waste through individualized prescribing and dispensing. Methods: Individual semi-structured interviews were conducted via conference calls with pharmacists and physicians prescribing and dispensing medication to outpatients of eleven Dutch hospitals. An interview guide based on the Theory of Planned Behaviour was developed. Questions related to participant's view on medication waste, current prescribing/dispensing behaviour and intention to personalising prescribing/dispensing quantities. Data was thematically analysed, following a deductive approach based on the Integrated Behavioural Model.Results: Nineteen out of 45 (42%) healthcare providers were interviewed, of whom eleven were pharmacists and eight physicians. Factors influencing individualized prescribing and dispensing by healthcare providers were identified and categorized in seven themes: (1) attitude: beliefs about consequences of waste, as well as perceived benefits and concerns of the intervention; (2) perceived norm: professional and social responsibilities; (3) personal agency: available resources; (4) knowledge and skills: intervention complexity; (5) salience of behaviour: perceived need from past experiences and evaluation of actions; (6) habit: prescribing and dispensing habits; and (7) situational factors: support for change, momentum for sustainable actions, need for guidance, triad collaboration and information provision. Conclusions: Healthcare providers perceive a strong professional and social responsibility to prevent medication waste yet feel bound by limited resources available to engage in individualized prescribing and dispensing. Situational factors, including leadership, organizational awareness and strong collaborations, could help healthcare providers to engage in individualized prescribing and dispensing. Through the identified themes, this study offers directions for designing and implementing an individualized prescribing and dispensing program to prevent medication waste.
