BACKGROUND AND OBJECTIVE The potentially inappropriate prescription by omission of a drug is defined as the failure to prescribe drugs that are clinically indicated. The objective of this article is to describe and analyse the evolution of inappropriate prescriptions by omission in nursing homes of a health department. MATERIAL AND METHODS Retrospective observational descriptive study carried out in nursing homes of the Valencia-Clínico-Malvarrosa health department during the period 2016-2018. All institutionalized patients during this period were included. The prevalence of potentially inappropriate prescriptions by omission was assessed based on version 2 of the START criteria. The variables came from the electronic medical records of ambulatory care of the Conselleria de Sanitat (Abucasis). RESULTS 2251 different patients were selected, mean age of 79,53years, 69% women, and an average of 4,60 chronic drugs/resident. A total of 2647 inappropriate prescriptions by omission were identified during the study period, and the results were similar during these 3years. The most prevalent START criteria were those related to the musculoskeletal system and the cardiovascular system, and those related to analgesic consumption. The mean value of inappropriate prescriptions by omission prevalence for the period studied were 39.54%. CONCLUSION The results of our study confirm a high prevalence of potentially inappropriate prescriptions by omission in residents of nursing homes, and the maintenance of this prevalence during the 3years of the study.
