Factors associated to potentially inappropriate prescribing in older patients according to STOPP/START criteria: MoPIM multicentre cohort study

Objectives The objectives of the present analyses are to estimate the frequency of potentially inappropriate prescribing (PIP) at admission according to STOPP/START criteria version 2 in older patients hospitalised due to chronic disease exacerbation as well as to identify risk factors associated to the most frequent active principles as potentially inappropriate medications (PIMs). Methods A multicentre, prospective cohort study including older patients (≥65) hospitalized due to chronic disease exacerbation at the internal medicine or geriatric services of 5 hospitals in Spain between September 2016 and December 2018 was conducted. Demographic and clinical data was collected, and a medication review process using STOPP/START criteria version 2 was performed, considering both PIMs and potential prescribing omissions (PPOs). Primary outcome was defined as the presence of any most frequent principles as PIMs, and secondary outcomes were the frequency of any PIM and PPO. Descriptive and bivariate analyses were conducted on all outcomes and multilevel logistic regression analysis, stratified by participating centre, was performed on the primary outcome. Results A total of 740 patients were included (mean age 84.1, 53.2% females), 93.8% of them presenting polypharmacy, with a median of 10 chronic prescriptions. Among all, 603 (81.5%) patients presented at least one PIP, 542 (73.2%) any PIM and 263 (35.5%) any PPO. Drugs prescribed without an evidence-based clinical indication were the most frequent PIM (33.8% of patients); vitamin D supplement in older people who are housebound or experiencing falls or with osteopenia was the most frequent PPO (10.3%). The most frequent active principles as PIMs were proton pump inhibitors (PPIs) and benzodiazepines (BZDs), present in 345 (46.6%) patients. This outcome was found significantly associated with age, polypharmacy and essential tremor in an explanatory model with 71% AUC. Conclusions PIMs at admission are highly prevalent in these patients, especially those involving PPIs or BZDs, which affected almost half of the patients. Therefore, these drugs may be considered as the starting point for medication review and deprescription. Trial registration number NCT02830425

Excessive polypharmacy and potentially inappropriate prescribing in 147 care-homes: cross-sectional study

BackgroundCare-home residents often have multiple cognitive and physical impairments and are at high risk of adverse drug events (ADEs).AimDescribe excessive polypharmacy and potentially inappropriate prescribing predisposing care-home residents to ADEs.Design and SettingCross-sectional analysis of all dispensed prescriptions for residents of 147 care-homes.MethodPrevalence of excessive polypharmacy was examined using multilevel logistic regression, by modelling associations between individual and care-home predictors with excessive polypharmacy (≥10 drugs). Prescribing of drugs known to increase the risk of eight clinically important ADE categories was examined. Drugs prescribed within each ADE category, for each resident, were counted.Results32.3% of residents had excessive polypharmacy, which was more common in residents aged 70–74 years (aOR =1.86 [1.04–3.34]) and 80–84 years (aOR =1.75 [1.01–3.02]), living in a residential care-home (aOR =1.50 [95%CI 1.19–1.88]), and located in Fife (aOR =1.37 [1.09–1.71]). Excessive polypharmacy was less common in residents with dementia (aOR =0.73 [0.64–0.84]). 8.9% (5.9%–11.6%) of the variation was attributable to care-home predictors. Potentially inappropriate prescribing of ≥2 drugs was seen across all ADE categories with highest prevalence seen in drugs predisposing to constipation (35.8%), sedation (27.7%), and renal injury (18.0%).ConclusionsExcessive polypharmacy is common in care-home residents and is associated with both individual and care-home predictors. Potentially inappropriate prescribing of drugs that predisposed residents to all included ADEs categories is common. Research is needed to support and evaluate safe care-home prescribing practices.

Prescribing cascades in community-dwelling adults: protocol for a systematic review

Introduction: Internationally, health systems face the challenge of managing a growing ageing population living with multimorbidity and polypharmacy. Potentially inappropriate prescribing is common among patients with polypharmacy, increasing the risk for adverse drug reactions (ADRs). Several prescribing indicator sets exist to improve prescribing and reduce potentially inappropriate prescribing, but do not address prescribing cascades. Prescribing cascades occur when a medication is prescribed to treat an ADR to another prescribed medication, whether intentionally or unintentionally, and constitute an important area to consider when characterising problematic polypharmacy. This is a protocol for a systematic review examining prescribing cascades in community-dwelling adults. Methods: The review will be reported adhering to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A systematic search of Medline (Ovid), EMBASE, PsycINFO, CINAHL and the Cochrane Library will be conducted from inception to March 2021, using a predetermined strategy. Grey literature will be searched using Open Grey, MedNar, Dart Europe, and the Turning Research Into Practice (TRIP) databases. No restrictions will be placed on language or publication year. Inclusion criteria are: population - community-dwelling adults (≥18 years); risk - prescription medication with the potential to cause side effects; outcomes - initiation of a new medicine to ‘treat’ or reduce the risk of experiencing an ADR. Prospective and retrospective cohort studies, case control and case series studies will be included. Two reviewers will independently screen titles and abstracts; studies meeting inclusion criteria will undergo independent full-text screening by two reviewers. A narrative synthesis will be conducted. Study quality will be independently assessed using the relevant Joanna Briggs Institute Critical Appraisal Checklist. Discussion: This systematic review will identify examples of prescribing cascades for community-dwelling adults and contribute to developing an evidence base regarding such cascades.

The Prevalence of Potentially Inappropriate Prescribing in the Elderly at the Primary Care Level in Kazakhstan

BACKGROUND: These potentially inappropriate prescribing is associated with the development of undesired medical reactions in elderly patients, and increase the frequency of hospitalizations, the number of aggravations and the cost of treatment. All of these adverse events are preventable. For detection of PIP and to prevent the adverse drug reactions (ADRs) in elderly patients, it is necessary to screen for potentially inappropriate prescribing. AIM: The aim of the study is to study the prevalence of PIP and the factors associated with these prescriptions at the level primary link in Kazakhstan. METHODS: A prospective descriptive study was carried out at the primary care level, in five clinics in Kazakhstan. The study involved 205 patients over 65 years old who received regular outpatient treatment for chronic diseases. Patients’ current diagnoses and prescription medicines were reviewed and the STOPP and START tools applied. RESULT: The prevalence of PIP in terms of STOPP criteria was 54% (114 patients). In general, we have identified 181 cases of PIP. The most commonly prescribed PIP were moxonidine (20%), glimeperide (16.5%), and PPI (20%). The prevalence of prescribing omissions in terms of START criteria was 22% (48 patients). Overall 66 cases of prescribing omissions were identified. The most commonly prescribed omissions were statins (6%) and ACE inhibitors (4%). Comparative analysis revealed a statistically significant effect of polymorbidity on the prevalence of PIP (p < 0.001) and number of prescribed medicines on the prevalence of PIP (p < 0.05). We have found a statistically significant effect of age on the presence of prescribing omissions of patients. (p < 0.001) CONCLUSION: Our results showed a high prevalence of potentially inappropriate prescribing at the primary care level in Kazakhstan. Screening tools should be incorporated into the everyday practice of primary care doctors.
