Background and Importance Potencially inappropriate medication prescription can increase the risk of adverse drug reactions (ADRs). Therefore, multiple tools have been developed to detect inappropriate prescriptions. STOPP (Screening Tool of Older Person’s Prescriptions)/START (Screening Tool to Alert to Right Treatment) criteria is one of them.
Aim and Objectives To analyse inappropriate prescriptions (IP) or the need of potencial prescriptions in polymedicated institutionalised patients in order to improve patients safety.
Material and Methods A descriptive, transversal study was performed in September 2022. We included all polymedicated residents (>6 drugs) of a nursing home attached to a Pharmacy Department. Data collect were age, sex, number of medications/resident and drugs prescribed. STOPP/START criteria v.2. was applied to detect inappropriate prescriptions or the need of potencial treatment. Data were collected from electronic prescription programme ATHOS-Prisma and computerised medical record Diraya.
Results A total of 50 patients were included, 66% men. The median age was 73 years (range: 69-83). Average drugs prescribed by residents was 10 (6-21).
Seventy-two percent of the residents (36) presented at least one STOPP criteria. Total IPs were 142, with an average of 5 IPs per resident (0-7). Most prevalent were treatment duration longer than defined (72%), prolonged use (> 4 weeks) of benzodiazepines (72%), drugs that adversely affect fallers (most related to benzodiazepines) (72%) and prescription of two drugs within the same class (22%).
Regarding START criteria, 23 residents (42%) presented any prescription initiation criteria. The total potencial prescribing omission were 26, with an average of 1 per resident (0-2). The most common were: use of laxatives in patients with opioid treatments (47,8%) and vitamin D supplements in older patients (34,8%).
Conclusion and Relevance STOPP criteria was the most frequently found. The majority relationed with inappropriate duration or duplicity of benzodiazepin treatment.
For START criteria, the indication of laxatives for patients receiving opioids on a regular basis was the most frequent potencial prescribing omission.
The use of STOPP/START criteria could improve patients safety, which are able to detect the inappropriate prescription of some drugs in addition to the omission of potencial indicated medication.
