High rate of psychotropic medications use in elderly people has been reported in the literature. Potentiality inappropriate prescriptions (PIPs) is very common as well. This issue has not been investigated in Oman previously. The aim of our study was to assess the patterns of psychotropic medications prescribed for older adults in the psychiatry clinics in Oman, screen for PIPs and plan for future actions to minimize inappropriate prescriptions.
This is a cross sectional descriptive study using the information in patient's medical records. It was conducted in 12 health care institutions which equally represent all Governorates of Oman. All patients who aged ≥ 60 years old who attended psychiatry clinics from January 2019 to June 2021 and were prescribed psychotropic medications were included. All psychotropic drugs were evaluated including: antidepressants, antipsychotics, Mood stabilizers and hypnotics. STOPP criteria were applied to detect PIPs.
1409 patients (70%) out of 1995 elderly patients who attended the psychiatry clinics in the study period as a new case were prescribed psychotropic medications. Rate of polypharmacy in our study is 38.9%. The most common medications prescribed were risperidone (18.1%) from the antipsychotic category, citalopram (23%) from the antidepressant group and promethazine (30.1%) from the hypnotics group. Regarding the use of sedative medications,18.5% of the patients were prescribed a benzodiazepine and 35.6% of them were prescribed an antihistamine. When assessed the pattern of medications prescribed in healthy people compared to people with different categories of major medical morbidities, no differences were observed. We found 130 (9.3%) potentially inappropriate prescriptions in our study based on STOPP criteria which included use of long-acting benzodiazepine (Diazepam), prescription of anticholinergic medication to treat extrapyramidal side effects (procyclidine) and use of tricyclic antidepressants in specific categories of medical diseases.
The patterns of psychotropic prescriptions for older adults in the outpatient setting in Oman raise concerns about 2 main issues: psychotropic polypharmacy and high rate of benzodiazepines and antihistamines use. This warrants further investigation of these issues in separate studies to identify risk factors. We also recommend implementing certain actions to minimize inappropriate prescriptions including reviewing the availability of appropriate psychotropic medications for this age group in Oman, creating a national guideline for prescribing and providing continuous medical education to the physicians in the primary and secondary health care institutions regarding this aspect.
