Elderly Patients in Primary Care are Still at Risks of Receiving Potentially Inappropriate Medications.

ABSTRACT:

Background

Most older adults with comorbidities in primary care clinics use multiple medications and are at risk of potentially inappropriate medications (PIMs) prescription.

Objective

This study examined the prevalence of polypharmacy and PIMs using Thai criteria for PIMs.

Methods

This study was a retrospective cross-sectional study. Data were collected from electronic medical records in a primary care clinic in 2018. Samples were patients aged ≥65 years old with at least 1 prescription. Variables included age, gender, comorbidities, and medications. The list of risk drugs for Thai elderly version 2 was the criteria for PIMs. The prevalence of polypharmacy and PIMs were calculated, and multiple logistic regression was conducted to examine associations between variables and PIMs.

Results

Of 2806 patients, 27.5% and 43.7% used ≥5 medications and PIMs, respectively. Of 10 290 prescriptions, 47% had at least 1 PIM. The top 3 PIMs were anticholinergics, proton-pump inhibitors, and nonsteroidal anti-inflammatory drugs (NSAIDs). Polypharmacy and dyspepsia were associated with PIM prescriptions (adjusted odds ratio 2.48 [95% confident interval or 95% CI 2.07-2.96] and 3.88 [95% CI 2.65-5.68], respectively).

Conclusion

Prescriptions with PIMs were high in the primary care clinic. Describing unnecessary medications is crucial to prevent negative health outcomes from PIMs. Computer-based clinical decision support, pharmacy-led interventions, and patient-specific drug recommendations are promising interventions to reduce PIMs in a primary care setting.

Project description:Background and aimsA potentially inappropriate medication (PIM) is defined as a drug-carrying risks outweighing the expected clinical benefits. Elderly patients with chronic kidney disease (CKD) are particularly at higher risk of drug-related toxicities. In Lebanon, no studies have been conducted regarding the prescribing of PIMs in hospitalized CKD patients. This study aimed to check the prevalence of PIMs using the American Geriatrics Society (AGS) Beers criteria in elderly patients with advanced CKD stages including dialysis and to identify possible risk factors that may be associated with prescribing PIMs in this population.MethodsA retrospective cross-sectional study was conducted on patients with advanced CKD above the age of 65 years and admitted between January 2019 and June 2019 to two University Hospitals in Beirut, Lebanon. We used multiple logistic regression analysis to determine which factors were associated with prescription of PIMs according to AGS Beers criteria-2019.ResultsThe study sample included 199 patients with renal dysfunction, 75.9% were aged 70 years or more, 53.8% were females, and 61.8% were prescribed five drugs or more. Eighty-two patients were receiving hemodialysis (41.2%). PIMs prevalence was 34.1% (68/199 patients) according to Beers criteria in elderly patients with advanced CKD stages.The most frequently prescribed PIMs were ranitidine (39.1%), enoxaparin (25%), tramadol (9.8%), and ciprofloxacin (5.4%). Polypharmacy (OR 2.1, CI 95% 1.58-2.79), a higher number of comorbidities (OR 3.01, CI 95% 1.43-6.30), and coronary artery diseases (OR 3.14 CI 95% 1.44-6.85) were the factors associated with an increased risk of at least one PIM prescription.ConclusionOur study found that one out of three patients with advanced CKD had at least one PIM according to the latest Beers criteria. A large proportion of inappropriate prescribing is preventable by increasing awareness of prescribing physicians to the explicit lists of PIMs.

Project description:ImportanceTime is a valuable resource in primary care, and physicians and patients consistently raise concerns about inadequate time during visits. However, there is little evidence on whether shorter visits translate into lower-quality care.ObjectiveTo investigate variations in primary care visit length and quantify the association between visit length and potentially inappropriate prescribing decisions by primary care physicians.Design, setting, and participantsThis cross-sectional study used data from electronic health record systems in primary care offices across the US to analyze adult primary care visits occurring in calendar year 2017. Analysis was conducted from March 2022 through January 2023.Main outcomes and measuresRegression analyses quantified the association between patient visit characteristics and visit length (measured using time stamp data) and the association between visit length and potentially inappropriate prescribing decisions, including inappropriate antibiotic prescriptions for upper respiratory tract infections, coprescribing of opioids and benzodiazepines for painful conditions, and prescriptions that were potentially inappropriate for older adults (based on the Beers criteria). All rates were estimated using physician fixed effects and were adjusted for patient and visit characteristics.ResultsThis study included 8 119 161 primary care visits by 4 360 445 patients (56.6% women) with 8091 primary care physicians; 7.7% of patients were Hispanic, 10.4% were non-Hispanic Black, 68.2% were non-Hispanic White, 5.5% were other race and ethnicity, and 8.3% had missing race and ethnicity. Longer visits were more complex (ie, more diagnoses recorded and/or more chronic conditions coded). After controlling for scheduled visit duration and measures of visit complexity, younger, publicly insured, Hispanic, and non-Hispanic Black patients had shorter visits. For each additional minute of visit length, the likelihood that a visit resulted in an inappropriate antibiotic prescription changed by -0.11 percentage points (95% CI, -0.14 to -0.09 percentage points) and the likelihood of opioid and benzodiazepine coprescribing changed by -0.01 percentage points (95% CI, -0.01 to -0.009 percentage points). Visit length had a positive association with potentially inappropriate prescribing among older adults (0.004 percentage points; 95% CI, 0.003-0.006 percentage points).Conclusions and relevanceIn this cross-sectional study, shorter visit length was associated with a higher likelihood of inappropriate antibiotic prescribing for patients with upper respiratory tract infections and coprescribing of opioids and benzodiazepines for patients with painful conditions. These findings suggest opportunities for additional research and operational improvements to visit scheduling and quality of prescribing decisions in primary care.
