The Barriers to Deprescription in Older Patients: A Survey of Spanish Clinicians

Description

Background and objective: There are barriers to deprescription that hinder its implementation in clinical practice. The objective of this study was to analyse the main barriers and limitations of the deprescription process perceived by physicians who care for multipathological patients. Materials and methods: The "deprescription questionnaire of elderly patients" was adapted to an online format and sent to physicians in geriatrics. Question 1 is a reference to establish agreement or disagreement with this practice. The influence of different aspects of deprescription was analysed via the demographic characteristics of the clinicians and perceptions of the various barriers (questions 2–9) by means of bivariate analysis. Based on the latter, a multivariate model was carried out to demonstrate the relationship between barriers and the degree of deprescription agreement among respondents. Results: Of the 72 respondents, 72.2% were in favour of deprescribing. Regarding the analyses, the demographic characteristics did not influence rankings. The deprescription of preventive drugs and consensus with patients were associated with a positive attitude towards deprescribing, while withdrawing drugs prescribed by other professionals, time constraints and patient reluctance emerged as possible barriers. The only factor independently associated with deprescribing was lack of time. Conclusions: Time was found to be the main barrier to deprescription. Training, the creation of multidisciplinary teams and integrated health systems are key facilitators.
