Healthcare professionals’ perceptions and perspectives on biosimilar medicines and the barriers and facilitators to their prescribing in UK: a qualitative study

Abstract

ObjectiveTo investigate UK healthcare professionals’ perceptions and perspectives towards biosimilar infliximab, etanercept and insulin glargine and the potential barriers and facilitators to their prescribing.DesignA cross-sectional qualitative study design was used.SettingFive hospitals within the West Midlands area in UK.Interventions30 min face-to-face, semistructured interviews of healthcare professionals.Participants22 healthcare professionals (consultants, nurses and pharmacists) participated in the semistructured interviews.OutcomesParticipants’ opinion and attitudes about biosimilars and the barriers and facilitators to the prescribing of infliximab, etanercept and insulin glargine biosimilars in gastroenterology, rheumatology and diabetology specialties.ResultsThis study showed that UK healthcare professionals had good knowledge of biosimilars and were content to initiate them. Healthcare professionals disagreed with biosimilar auto-substitution at pharmacy level and multiple switching. Subtle differences among healthcare professionals were identified in the acceptance of switching stable patients, indication extrapolation and cost savings sharing.ConclusionSafety and efficacy concerns, patients’ opinion and how cost savings were shared were the identified barriers to considering prescribing biosimilars. Real-life data and financial incentives were the suggested facilitators to increase biosimilar utilisation.
