Potentially inappropriate medication use based on two deprescribing criteria and related factors in patients with terminal cancer: A cross-sectional study

Polypharmacy and Potentially Inappropriate Medications in Patients With Advanced Cancer: Prevalence and Associated Factors at the End of Life

Background: Polypharmacy and potentially inappropriate medications (PIMs) impose a burden on patients with advanced cancer near the end of their lives. However, only a few studies have addressed factors associated with PIMs in such patients. Objective: To examine polypharmacy and factors associated with PIMs in end-of-life patients with advanced cancer. Design: Retrospective chart review. Setting/Subjects: We analyzed 265 patients with advanced cancer who died in a palliative care unit (PCU) or at home in a home medical care (HMC) from April 2018 to December 2022 in Japan. Measurements: Sociodemographic, clinical, and prescription data at the time of PCU admission or HMC initiation were collected from electronic medical records. PIMs were assessed using OncPal Deprescribing Guidelines. Results: Patients with advanced cancer with an average age of 76.3 years and median survival days of 20 were included in the analyses. The average number of medications was 6.4 (standard deviation = 3.4), and PIMs were prescribed to 50.2%. Frequent PIMs included antihypertensive medications, peptic ulcer prophylaxis, and dyslipidemia medications. A multivariate logistic regression analysis revealed that age ≥75 years (adjusted odds ratio [aOR] = 2.30, 95% confidence interval [CI] = 1.30-4.05), referral from an outpatient setting compared with inpatient setting (aOR = 2.06, 95% CI = 1.12-3.80), more than two comorbidities (aOR = 1.88, 95% CI = 1.08-3.29), and more than five medications (aOR = 1.84, 95% CI = 1.03-3.28) were associated with PIMs. Conclusions: Medication reconciliation is recommended at the time of transition to a PCU or HMC, especially for older patients with advanced cancer who were referred from an outpatient setting and present more comorbidities and prescriptions.

Deprescribing in older patients with advanced cancer referred to palliative care

OBJECTIVES

This study aimed to explore the prevalence of potentially inappropriate medications (PIMs) in a cohort of older adults with advanced cancer referred to palliative care. Secondary objectives were to describe the categories of identified PIMs and assess risk factors associated with their presence in this population.

METHODS

This retrospective, observational study evaluated patients with advanced cancer admitted to a tertiary university hospital in Madrid, Spain and referred to palliative care between 1 January 2020 and 30 June 2020. Demographic, clinical, and pharmacotherapeutic data were obtained from the electronic medical records and regional databases. PIMs were assessed using the Screening Tool of Older Persons Prescriptions in Frail adults (STOPPFrail) criteria, V1.

RESULTS

Among 123 patients (median age 80 years (IQR 73.5-87), 64.2% male), 74% presented at least one PIM according to the STOPPFrail criteria. The most common categories of inappropriate medications were lipid-lowering therapies, proton pump inhibitors, calcium supplements, and oral antidiabetics. The number of chronic comedications was significantly associated with PIM presence.

CONCLUSIONS

Our study found a high prevalence of PIM among a cohort of older adults with advanced cancer and short life expectancy. This underlines the need for a comprehensive medication review to optimise pharmacotherapy in this population.
