Potentially inappropriate medications among elderly patients in community healthcare institutions in Beijing, China

Potentially inappropriate prescribing among older adults with hypertension in China: prevalence and related comorbidities across different outpatient settings

Purpose

Potentially inappropriate prescribing (PIP) is commonly encountered in older adults; yet, there is limited information on the occurrence of PIP among older adults with hypertension. This study aims to determine and compare the prevalence of PIP and its association with comorbidities in older adult outpatients with hypertension across hospitals and community health centers (CHCs).

Methods

This 3-year (2015-2017) repeated cross-sectional study used electronic medical records from Shenzhen, China, involving 62 hospitals and 678 primary medical institutions. PIP was defined using the 2019 Beers Criteria. Older adults (≥65 years) with hypertension and at least one outpatient prescription were included. Modified Poisson regression analysis was used to assess the association between chronic comorbidities, healthcare settings, and PIP.

Results

The prevalence of PIP in old adult outpatients with hypertension in 2015, 2016, and 2017 was 46.32%, 46.98%, and 46.58% in hospitals, with a sample size of 38,411, 46,235, and 50,495, respectively, and 29.14%, 26.66%, and 29.84% in CHCs, with a sample size of 26,876, 29,434, and 34,775 respectively. The top four most popular PIP in hospitals and CHCs was proton-pump inhibitors (PPIs), diuretics, benzodiazepines, and non-cyclooxygenase-selective non-steroidal anti-inflammatory drugs (NSAIDs), respectively. PIP was most associated with chronic gastrointestinal disease (adjusted prevalence ratio = 1.54, 95% confidence interval [CI] = 1.50-1.59) and mental and behavioral disorders (adjusted prevalence ratio = 1.49, 95% CI = 1.46-1.53) in hospitals and with mental and behavioral disorders (adjusted prevalence ratio = 1.99; 95% CI = 1.95-2.03) and musculoskeletal system and connective tissue disorders (adjusted prevalence ratio = 1.33; 95% CI = 1.31-1.36) in CHCs. The prevalence of PIP was significantly higher in hospital settings than in CHCs (adjusted prevalence ratio = 1.65; 95% CI = 1.63-1.66).

Conclusion

Among older adult outpatients with hypertension in Shenzhen, PIP was more prevalent in hospitals than in CHCs. The comorbidities most strongly associated with PIP were chronic gastrointestinal disease and mental and behavioral disorders in hospitals and mental and behavioral disorders in CHCs. Clinical pharmacy integration needs to be considered to reduce inappropriate prescribing in this vulnerable population.

Comparison of four criteria for potentially inappropriate medications in older patients with newly diagnosed non-small cell lung cancer

BACKGROUND

Potentially inappropriate medication (PIM) use is a common problem among older patients. This study aimed to compare the prevalence of PIMs in older patients with newly diagnosed non-small cell lung cancer (NSCLC), and to identify the correlates of PIMs.

RESEARCH DESIGN AND METHODS

A secondary analysis of a prospective cohort study was conducted. Patients were enrolled from January 2014 to December 2020 and information were extracted from patients' electronic medical records (EMRs). We evaluated the PIMs using four different PIM criteria. The concordance among the four PIM criteria was calculated using kappa tests. The possible risk factors associated with PIMs were analyzed by multivariate logistic regression.

RESULTS

The prevalence of at least one PIM identified by the four criteria ranged from 25.1% to 48.2% among 514 patients. There was moderate consistency between the GO-PIM scale and the AGS/Beers criteria, while poor consistency with the other criteria (the STOPP criteria and the Chinese criteria). Polypharmacy was found to be significantly associated with the occurrence of PIMs in all criteria (p < 0.001).

CONCLUSIONS

Our results showed a high prevalence of PIMs in older patients with NSCLC, which was significantly associated with polypharmacy, and the consistency across the four criteria was poor-to-moderate.

Identification of Barriers for Active Disease Management and of Medication-Related Problems through Therapeutic Patient Education in Older Home-Care Patients

Combining therapeutic patient education (TPE) with a medication review service could foster the adoption of appropriate lifestyles by patients and support care-providers in identifying strategies to improve the quality of prescribed care. This study aimed to identify barriers experienced by patients in managing their diseases and medication-related problems. This was a monocentric, case series, observational study involving home-care patients from the Local Health Authority ASL TO4. Patients were enrolled for a TPE intervention where drug therapies and patient habits were collected through narrative interviews. Medication review was performed to identify potentially inappropriate prescriptions (PIPs). Twenty patients (13 females) with a mean age of 74.7 years were enrolled. Patients had an average of 4.3 diseases and 80.0% of them were treated with ≥5 daily medications. The main PIPs involved ibuprofen, furosemide and pantoprazole. The qualitative analysis of the interviews identified seven macro-themes relating to different aspects of medication management: therapy; diseases; patient; patient journey; professionals; family and caregivers; drug information. The results of this study revealed some critical aspects related to the treatment path and healthcare professionals. These results will be used to plan educational interventions for polypharmacy patients to improve medication adherence and the understanding and management of diseases.

Potentially inappropriate medications among older patients with Parkinson's disease: a cross-sectional analysis of a national health insurance database in China

BACKGROUND

With the rapid aging trend of China's population, the issue of drug rational use in older adults has become more and more prominent. Parkinson's disease (PD) is the one of the most common age-related neurodegenerative disorders. Pharmaceutical treatment plays a cardinal role in alleviating motor and non-motor symptoms to improve the quality of life of patients with PD. Patients with PD have complex medical needs yet little is known about the use of potentially inappropriate medications (PIM) among them in China. We quantify the prevalence of PIM use and identify its predictors among older persons with PD in China.

METHODS

We conducted a cross-sectional analysis using a national representative database of all medical insurance beneficiaries across China, extracting records of ambulatory visits of older adults with PD between 2015 and 2017. Beneficiaries aged 65 and above were eligible for inclusion. The prevalence of patients exposed to overall PIMs and PIMs related to motor and cognitive impairment was calculated based on Beers Criteria 2015 version. Potential predictors of PIM concerning patients' characteristics were estimated using multivariate logistic regression.

RESULTS

A total of 14,452 older adults with PD were included. In total, 8,356 (57.8%) patients received at least one PIM; 2,464 (17.1%) patients received at least one motor-impairing PIM and 6,201 (42.9%) patients received at least one cognition-impairing PIM. The prevalence of overall PIM use was higher in patients of older age group (54.7% [65-74] vs. 59.5% [75-84; OR, 1.22; 95% CI, 1.14-1.31] vs.65.5% [≥ 85; OR, 1.58; 95% CI, 1.38-1.80) and females (61.4% [female] vs. 55.0% [males; OR, 0.77; 95% CI, 0.72-0.82).

CONCLUSIONS

Prescribing PIMs for older adults with PD was common in China, especially for females and older age groups, yet younger patients were more inclined to be prescribed with motor or cognition-impaired PIMs. Our findings represent a clear target awaiting multidimensional efforts to promote the rational prescribing of medications for this vulnerable population.

A combination of Beers and STOPP criteria better detects potentially inappropriate medications use among older hospitalized patients with chronic diseases and polypharmacy: a multicenter cross-sectional study

BACKGROUND

Research on potentially inappropriate medications (PIM) and medication-related problems (MRP) among the Chinese population with chronic diseases and polypharmacy is insufficient.

OBJECTIVES

This study aimed to investigate the prevalence of PIM and MRP among older Chinese hospitalized patients with chronic diseases and polypharmacy and analyze the associated factors.

METHODS

A retrospective cross-sectional study was conducted in five tertiary hospitals in Beijing. Patients aged ≥ 65 years with at least one chronic disease and taking at least five or more medications were included. Data were extracted from the hospitals' electronic medical record systems. PIM was evaluated according to the 2015 Beers criteria and the 2014 Screening Tool of Older Persons' Prescriptions (STOPP) criteria. MRPs were assessed and classified according to the Helper-Strand classification system. The prevalence of PIM and MRP and related factors were analyzed.

RESULTS

A total of 852 cases were included. The prevalence of PIM was 85.3% and 59.7% based on the Beers criteria and the STOPP criteria. A total of 456 MRPs occurred in 247 patients. The most prevalent MRP categories were dosages that were too low and unnecessary medication therapies. Hyperpolypharmacy (taking ≥ 10 drugs) (odds ratio OR 3.736, 95% confidence interval CI 1.541-9.058, P = 0.004) and suffering from coronary heart disease (OR 2.620, 95%CI 1.090-6.297, P = 0.031) were the influencing factors of inappropriate prescribing (the presence of either PIM or MRP in a patient).

CONCLUSION

PIM and MRP were prevalent in older patients with chronic disease and polypharmacy in Chinese hospitals. More interventions are urgently needed to reduce PIM use and improve the quality of drug therapies.

Physicians’ Knowledge, Altitudes, and Perceived Barriers of Inappropriate Prescribing for Older Patients in Shanghai, China

Background: Inappropriate medication use is common around the world, particularly among older patients, and, despite potentially being preventable, often leads to adverse clinical and economic outcomes. However, there is a dearth of information regarding this prominent issue in China.

Objectives: To evaluate the extent to which the physician can correctly identify potentially inappropriate medication (PIM) in older patients and to understand physicians’ attitudes towards improving PIM knowledge.

Methods: An online, cross-sectional survey was conducted anonymously among practicing physicians in China from November through December 2020. Knowledge of PIM was accessed using seven clinical vignettes covering a wide variety of therapeutic areas. Source of information and perceived barriers regarding PIM were also evaluated. We performed the ordinary least square regression analysis to understand the potential factors related to physicians’ knowledge of PIM.

Results: A total of 597 study participants were included in the analysis. More than half of them had never heard of any screening tool for PIMs (n = 328, 54.9%) and the most frequently acknowledged tool was the China PIM Criteria (n = 259, 43.4%). For the seven clinical vignettes testing physicians’ knowledge on the medications that should be generally avoided in older patients, the mean score was 2.91 points out of 7 (SD: 1.32), with the median score of three points (IQR: 2–4). Only one-third of the respondents were feeling confident when prescribing for older patients (n = 255, 35.08%). Package inserts have been used as the major source of PIM information (always, n = 177, 29.65%; frequently, n = 286, 47.91%). Perceived barriers to appropriate prescribing include polypharmacy (n = 460, 77.05%), lack of formal education on prescribing for the older patients (n = 428, 71.69%).

Conclusion: In this online survey evaluating physicians’ ability to detect PIM for older patients, approximately 40% of PIM were recognized, suggesting an insufficient level of knowledge about appropriate prescribing.

Prevalence of Polypharmacy and Potentially Inappropriate Medications Use in Elderly Chinese Patients: A Systematic Review and Meta-Analysis

Objectives: Polypharmacy and potentially inappropriate medication (PIM) use among elderly Chinese patients have not yet been investigated by systematic review and meta-analysis. The purposes of this study were to investigate the prevalence of polypharmacy and PIM use and the risk factors associated with PIM use in elderly Chinese patients.

Methods: Databases including PubMed, EMBase, and Web of Science were searched to collect studies which used Chinese criteria, Beers criteria, or STOPP criteria to evaluate the PIM status of elderly Chinese patients from inception to August 2021 (PROSPERO Code No: CRD42021262821). Observational studies reporting the prevalence of polypharmacy and PIM use in elderly Chinese patients were meta-analyzed. The pooled prevalence and risk ratio (RR) were calculated with a 95% confidence interval (CI).

Results: A total of 8 articles involving 4,558,786 patients were included. The overall prevalence of polypharmacy (concomitant use of more than 5 medicines) and PIM use pooled by meta-analysis in Chinese older patients was 48% (95% CI: 0.17, 0.79, p = 0.003) (inpatients 73%, outpatients 23%) and 39% (95% CI: 0.25, 0.54, p < 0.001) (inpatients 50%, outpatients 29%), respectively. Polypharmacy (RR: 2.03, 95% CI: 1.13, 3.64) was significantly associated with PIM use.

Conclusion: This meta-analysis demonstrated a high prevalence of polypharmacy and PIM use among elderly patients in China. Affected by the quantity and quality of the included studies, the aforementioned conclusions need to be confirmed by large samples and high-quality studies.

Protocol of a tailored educational intervention for general practitioners on potentially inappropriate medications among older patients at community healthcare institutions in Beijing, China: a cluster-randomised controlled trial

INTRODUCTION

Prescribing of potentially inappropriate medications (PIMs) has become a prominent issue of public concern among elderly patients. However, no research has involved interventions on PIMs of Chinese elderly patients seeking care at primary healthcare. This study aims to evaluate the effectiveness of a tailored educational intervention programme for general practitioners (GPs), aiming at reducing the occurrence of PIMs in elderly patients.

METHODS AND ANALYSIS

This is a parallel group, controlled, cluster-randomised trial, with blinded evaluation of outcomes and data analysis, and un-blinded intervention. Twenty primary community healthcare stations (CHSs) in Dongcheng district in Beijing will be randomised to intervention and control arm with an allocation ratio of 1:1. GPs in CHSs randomised to the intervention arm will receive a two-component intervention: general training of PIMs and distribution of PIMs handbook. GPs in the control arm will assess and manage patients according to the institutions' routine practice. The primary outcome is the change in PIMs patient visit rate.

ETHICS AND DISSEMINATION

Ethics committee approval of this study was obtained from Peking University Institution Review Board (IRB00001052-19074). The findings will be published in scientific and conference presentations.
