Abstract
OBJECTIVE Medication errors can have detrimental effects on patient outcomes, yet there are limited data on the prevalence of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) among older adult inpatients in New Zealand (NZ). This study investigated exposure to PIMs and PPOs in older adults in a New Zealand hospital. METHODS Electronic medical records of 846 older adults (≥ 65 years) discharged from the Auckland District Health Board between June 2020 and May 2021 were retrospectively reviewed to extract data on sociodemographic, medication and diagnostic information. STOPP/START version 2 was used to evaluate PIMs and PPOs on admission and discharge. RESULTS The mean age was 77.47 ± 8.12 years, and 51% were female. On admission, 48% had ≥1 PIMs and 40% had ≥1 PPOs. On discharge, 45% had ≥1 PIMs and 40% had ≥1 PPOs. Increasing age (adjusted odds ratio [AOR] = 1.02, 95% CI [confidence interval] 1.01, 1.04), number of medicines (AOR = 1.23, CI 1.17, 1.29) and 28-day admission history (AOR = 1.58, CI 1.15, 2.18) were associated with higher odds of PIMs use on admission. At discharge, the number of medicines (AOR = 1.19, CI 1.13, 1.25) and history of readmission (AOR = 1.47, CI 1.08, 2.02) were associated with higher odds of PIMs. Female patients had higher odds of PPOs both on admission (AOR = 1.35, CI 1.02, 1.78) and discharge (AOR = 1.34, CI 1.01, 1.78). Māori, Asian and Pacific patients were more likely to have prescribing omissions compared to NZ Europeans. CONCLUSIONS Prescribing omissions and inappropriate medications were common in older inpatients. There were differences observed between different ethnic groups, with NZ Europeans having fewer omissions than other ethnic groups. These findings highlight key opportunities for health-care providers to improve medication use in older adults in NZ.

Ther Adv Psychopharmacol 2023; 13:20451253231211576. [PMID: 38022837 PMCID: PMC10666674 DOI: 10.1177/20451253231211576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Accepted: 10/16/2023] [Indexed: 12/01/2023] Open
Abstract
Background Potentially inappropriate prescribing (PIP) is frequent in geriatrics and results in an increased risk for adverse effects, morbidity, mortality and reduced quality of life. Research on PIP in psychiatry has mainly focused on elderly patients and inpatients. Objectives To determine the prevalence and the predictors of PIP of psychotropic medication in outpatients with severe mental illness. Design This study is part of the Muva study, a pragmatic open Stepped Wedge Cluster Randomized Trial of a physical activity intervention for patients (age ⩾ 16 years) with severe mental illness. Methods A structured medication interview, questionnaires on social functioning, quality of life and psychiatric symptoms, and BMI and waist circumference measurements were performed followed by a structured medication review. Patients were divided into groups: PIP versus no PIP. Between-group differences were calculated and a multivariate binary logistic regression was performed to examine predictors for PIP. A receiver operating characteristics analysis was performed to determine the area under the curve (AUC). Results In 75 patients, an average of 5.2 medications of which 2.5 psychotropic medication was used. 35 (46.7%) patients were identified with PIP. Unindicated long-term benzodiazepine use was the most frequently occurring PIP (34.1%). Predictors of PIP were female gender [odds ratio (OR) = 4.88, confidence interval (CI) = 1.16-20.58, p = 0.03], number of medications (OR = 1.41, CI = 1.07-1.86, p = 0.02) and lower social functioning (OR = 1.42, CI = 1.01-2.00, p = 0.05). The AUC was 0.88 for the combined prediction model. Conclusion The prevalence of PIP of psychotropic medication in outpatients with severe mental illness is high. It is therefore important to identify, and where possible, resolve PIP by frequently performing a medication review with specific attention to females, patients with a higher number of medications and patients with lower social functioning. Trial registration This trial was registered in The Netherlands Trial Register (NTR) as NTR NL9163 on 20 December 2020 (https://trialsearch.who.int/Trial2.aspx?TrialID=NL9163).

Abstract
OBJECTIVE Geriatric patients account for a significant proportion of the collective treated by psychiatric consultation service in hospitals. In the Emergency Department (ED), psychotropic drugs are frequently recommended, notwithstanding their extensive side-effect profiles. This study sought to investigate medication safety of geriatric patients referred to psychiatric consultation service in the ED. METHODS Medication lists of 60 patients from the general internal medicine and trauma surgery EDs referred to psychiatric consultation service were analyzed. Utilizing PRISCUS list and Fit fOR The Aged (FORTA) classification, prescriptions of potentially inappropriate medications (PIMs) were assessed. RESULTS 84 drugs were newly prescribed following psychiatric consultations. The total number of drugs per patient was 5.4 ± 4.2 before psychiatric consultation and 6.5 ± 4.2 thereafter (p < .001). 22.6 % of the newly recommended drugs were PIMs according to the PRISCUS list, while 54.8 % were designated as therapeutic alternatives to PIMs. 54.8 % and 20.2 % of the newly recommended drugs were FORTA category C and D drugs, respectively. An average of 1.2 ± 1.7 drug-drug interactions (DDIs) existed before psychiatric consultation and 1.3 ± 1.9 DDIs thereafter (p = .08). CONCLUSION The majority of newly recommended drugs by psychiatric consultation service in the ED were designated as suitable therapeutic alternatives to PIMs according to the PRISCUS list, but had comparatively unfavorable ratings according to the FORTA classification, demonstrating discrepancies between these two PIM classification systems. Physicians delivering psychiatric consultation services in the ED should not solely rely on one PIM classification system.

Abstract
Adverse drug reactions (ADRs) constitute a frequent cause of hospitalization in older people. The risk of ADRs is increased by the prescription of potentially inappropriate medications for older people (PIMs). The PRISCUS list and the FORTA classification represent established tools to detect PIMs. The aim of the present study was to examine the prevalence and characteristics of PIM prescriptions on the gerontopsychiatric ward of a university hospital in Germany. To this aim, medication charts of 92 patients (mean age 75.9 ± 7.7 years; 66.3% female) were analyzed on a weekly basis until patient discharge by utilization of the PRISCUS list and the FORTA classification. Overall, 335 medication reviews comprising 2363 drug prescriptions were analyzed. 3.0% of the prescribed drugs were PIMs according to the PRISCUS list, with benzodiazepines and Z-drugs accounting for nearly half (49.3%) of all PIM prescriptions. 30.4% of the patients were prescribed at least one PRISCUS-PIM, while 43.5% of the study population took at least one FORTA class D drug. A considerable proportion of gerontopsychiatric patients were affected by PIMs; however, the overall number of PIM prescriptions in the study population was low. Further improvements in the quality of prescribing should target the use of sedating agents such as benzodiazepines and Z-drugs. Physicians should be aware of discrepancies between the PRISCUS list and the FORTA classification.
