Green hospital pharmacy: A sustainable approach to the medication use process in a tertiary hospital. / [Artículo traducido] Farmacia hospitalaria ecológica: un enfoque sostenible del proceso de utilización de medicamentos en un hospital de tercer nivel.

ABSTRACT

BACKGROUND: Sustainable management of healthcare waste has a positive impact on the global environment. In order to reduce it, the sustainable practice of the pharmacotherapeutic process in all its stages is essential. OBJECTIVE: To analyse the sustainability strategies proposed by the pharmacy service to reduce drug waste derived from the pharmacotherapeutic process. SECONDARY OBJECTIVES: To analyse the stage of the pharmacotherapeutic process and the number and type of drugs involved. METHODS: The study was carried out in a tertiary-level hospital. To coordinate the proposals, a referent pharmacist from every pharmacy department area was selected. Four stages of the process were evaluated (management, validation, dispensing and compounding), patients concerned were classified as outpatients or inpatients, and drugs potentially involved were analysed by the administration route Into oral or parenteral. RESULTS: Twenty eight ideas were proposed, which could affect more than 1200 drugs. 39.3% would affect the validation process, 17.9% the procurement management, 17.9% dispensing, and 7.1% the compounding. Implementation feasibility and acceptability of these proposals were evaluated. Those with the greatest potential were Limiting the duration of treatments when possible, favouring the implementation of computer prescription order entry, favouring the use of the oral route over the parenteral route, and implementing computers in the preparation areas to avoid the use of paper guides. DISCUSION: In our study, many ideas have been proposed by hospital pharmacists to improve the sustainability of the medication use process. When assessing these proposals by impact and feasibility, according to our results, shorten as much as possible the duration of treatments, computerization of the medication use process, and oral administration over intravenous should be prioritized in order to reduce environmental impact.
