Potentially inappropriate prescribing (PIP) in long-term care (LTC) patients: validation of the 2014 STOPP-START and 2012 Beers criteria in a LTC population--a protocol for a cross-sectional comparison of clinical and health administrative data

The impact of patient-facility language discordance on potentially inappropriate prescribing of antipsychotics in long-term care home in Ontario, Canada: a retrospective population health cohort study

BACKGROUND

Appropriate use of medication is a key indicator of the quality of care provided in long-term care (LTC). The objective of this study was to determine whether resident-facility language concordance/discordance is associated with the odds of potentially inappropriate prescribing of antipsychotics (PIP-AP) in LTC.

METHODS

We conducted a population-based, retrospective cohort study of LTC residents in Ontario, Canada from 2010 to 2019. We obtained resident language from standardized resident assessments, and derived facility language by determining the proportion of residents belonging to each linguistic group within individual LTC homes. Using linked administrative databases, we identified all instances of PIP-AP during a 1-year follow-up period. PIP-AP was defined using the STOPP-START criteria, which have previously been shown to predict adverse clinical events such as emergency department (ED) visits and hospitalizations. The association between linguistic factors and PIP-AP was assessed using adjusted multivariable logistic regression analysis.

RESULTS

We identified 198,729 LTC residents consisting of 162,814 Anglophones (81.9%), 6,230 Francophones (3.1%), and 29,685 Allophones (14.9%). The odds of PIP-AP of were higher for both Francophones (aOR 1.15, 95% CI 1.08-1.23) and Allophones (aOR 1.11, 95% CI 1.08-1.15) when compared to Anglophones. When compared to English LTC homes, French LTC homes had greater odds of PIP-AP (aOR 1.12, 95% CI 1.05-1.20), while Allophone homes had lower odds of PIP-AP (aOR 0.82, 95% CI 0.77-0.86). Residents living in language-discordant LTC homes had higher odds of PIP-AP when compared to LTC residents living in language-concordant LTC homes (aOR 1.07, 95% CI 1.04-1.10).

CONCLUSION

This study identified linguistic factors related to the odds of PIP-AP in LTC, suggesting that the linguistic environment may have an impact on the quality of care provided to residents.

Potentially Inappropriate Prescribing in Long-Term Care and its Relationship With Probable Delirium

OBJECTIVES

This study examined potentially inappropriate prescribing (PIP) of medication and its association with probable delirium among long-term care (LTC) residents in Ontario, Canada.

DESIGN

Population-based cross-sectional study using provincial health administrative data, including LTC assessment data via the Resident Assessment Instrument-Minimum Dataset version 2.0 (RAI-MDS 2.0).

SETTING AND PARTICIPANTS

LTC residents in Ontario between January 1, 2016, and December 31, 2019.

METHODS

We used residents' first RAI-MDS 2.0 assessment in the study period as the index assessment. Probable delirium was identified via the delirium Clinical Assessment Protocol. Medication use in the 2 weeks preceding assessment was captured using medication claims data. PIP was measured using the STOPP/START criteria and 2015 Beers criteria, with residents classified as having 0, 1, 2, or 3+ instances of PIP. Relationships between PIP and probable delirium was assessed via bivariate and multivariable logistic regression models.

RESULTS

The study population included 171,190 LTC residents (mean age 84.5 years, 66.8% female, 62.9% with dementia). More than half (51.8%) of residents had 1+ instances of PIP and 21% had 3+ instances of PIP according to the STOPP/START criteria; PIP prevalence was slightly lower when assessed using Beers criteria (36.5% with 1+, 11.1% with 3+). Overall, 3.7% of residents had probable delirium. The prevalence of probable delirium increased as the number of instances of PIP increased, with residents with 3+ instances of STOPP/START PIP being 1.66 times more likely (95% CI 1.56-1.77) to have probable delirium compared to those with no instances of PIP. Similar findings were observed when PIP was measured using the Beers criteria. Central nervous system (CNS)-related PIP criteria showed a stronger association with probable delirium than non-CNS-related PIP criteria.

CONCLUSIONS AND IMPLICATIONS

This population-based study highlighted that PIP was highly prevalent in long-term care residents and was associated with an increased prevalence of probable delirium.

Prevalence and Risk Factors Associated with Potentially Inappropriate Prescribing According to STOPP-2 Criteria among Discharged Older Patients-An Observational Retrospective Study

Pharmacokinetic and pharmacodynamic changes associated with old age, along with multimorbidity and polypharmacy might lead to inappropriate prescribing and adverse reactions. Explicit criteria such as the Screening tool of older people's prescribing (STOPP) are useful to identify potential inappropriate prescribing's (PIPs). Our retrospective study included discharge papers from patients aged ≥65 years, from an internal medicine department in Romania (January-June 2018). A subset of the STOPP-2 criteria was used to assess the prevalence and characteristics of PIPs. Regression analysis was performed to evaluate the impact of associated risk factors (i.e., age, gender, polypharmacy and specific disease). Out of the 516 discharge papers analyzed, 417 were further assessed for PIPs. Patients' mean age was 75 years, 61.63% were female and 55.16% had at least one PIP, with 81.30% having one or two PIPs. Antithrombotic agents in patients with significant bleeding risk was the most prevalent PIP (23.98%), followed by the use of benzodiazepines (9.11%). Polypharmacy, extreme (>10 drugs) polypharmacy, hypertension and congestive heart failure were found as independent risk factors. PIP was prevalent and increased with (extreme) polypharmacy and specific cardiac disease. Comprehensive criteria like STOPP should be regularly used in clinical practice to identify PIPs to prevent potential harm.

Potentially inappropriate medication in long-term care wards of a veteran hospital in Taiwan: Investigation using a spreadsheet-based rapid assessment tool

BACKGROUND

Multimorbidity and polypharmacy increase in the aging population and are accompanied by the use of potentially inappropriate medications (PIMs) and adverse drug events (ADEs). This study developed a rapid assessment tool to investigate PIM use among patients in long-term care wards.

METHODS

We retrospectively collected the data of patients in long-term care wards of a veteran hospital in Taiwan between July 2019 and June 2020. The patients with chronic diseases and medications were selected. The data, including gender, age, diagnosis, and medications, were deidentified. Nonchronic disease diagnosis and short-term and topical use medications were excluded. We used Microsoft Excel (Microsoft Corporation, Redmond, Washington, USA) and the 2019 version of the Beers Criteria to establish a rapid assessment tool. The correlations between the prevalence of PIM use and age, the number of diagnoses, and the number of medications were analyzed using SPSS version 23.

RESULTS

A total of 176 patients were included in this study, of which 76.7% (n = 135) were male and 23.3% (n = 41) were female. The average age of men was 82.1 years and that of women was 83.4 years. The average number of diagnoses for men was 5.5, and that for women was 7.3. The average number of medications for men was 5.8, and that for women was 6.5. The prevalence of PIM use was 59.1% (n = 104). Logistic regression revealed that the prevalence of PIM use may be associated with the number of medications ( p < 0.001; odds ratio = 1.378). Decision tree analysis revealed that patients who simultaneously used more than four medications exhibited a higher risk of PIM.

CONCLUSION

PIM use is a key factor causing ADEs among older adults. Therefore, comprehensive assessment of PIM use is necessary. This study designed a rapid assessment tool to simultaneously integrate and evaluate medications. Future studies may investigate the effectiveness of the proposed assessment tool.

Healthcare Costs Associated with Potentially Inappropriate Medication Prescribing Detected by Computer Algorithm Among Older Patients

INTRODUCTION

Potentially inappropriate medication prescribing (PIP) among older patients is associated with an increased risk of adverse events and hospitalization, and sometimes increased healthcare costs.

OBJECTIVE

The aim of this study was to explore the association between healthcare costs and PIP exposure among older patients.

METHODS

Analyses were conducted using data from the Multidomain Alzheimer Preventive Trial (MAPT). A computer algorithm was constructed to detect PIP based on various different explicit criteria-based tools, and the results were expressed in number of medication-related potential non-compliances (MRNCs). A prescription was considered potentially inappropriate if there were one or more MRNCs. We performed a cost analysis from the French National Health Insurance perspective, and also performed a multivariate analysis to identify the association between healthcare costs and PIP (number of MRNCs).

RESULTS

The computer algorithm analyzed medication prescribing from included patients (N = 1525 aged 75.3 ± 4.4 years; 64% women [n = 978]). PIP was associated with increased total healthcare costs and non-medication healthcare costs after adjusting for potential confounders. We also noted that healthcare costs tended to increase with the number of MRNCs. The mean additional healthcare costs were €517, €921, and €1669 per patient and year for patients with one or two MRNCs, three or four MRNCs, and five or more MRNCs, respectively, in comparison with patients with appropriate medication prescriptions.

CONCLUSION

These observations led us to conclude that interventions focused on reducing PIP could result in savings.

Potentially inappropriate medication and attitudes of older adults towards deprescribing

INTRODUCTION

Multimorbidity and polypharmacy are current challenges when caring for the older population. Both have led to an increase of potentially inappropriate medication (PIM), illustrating the need to assess patients' attitudes towards deprescribing. We aimed to assess the prevalence of PIM use and whether this was associated with patient factors and willingness to deprescribe.

METHOD

We analysed data from the LESS Study, a cross-sectional study on self-reported medication and on barriers and enablers towards the willingness to deprescribe (rPATD questionnaire). The survey was conducted among multimorbid (≥3 chronic conditions) participants ≥70 years with polypharmacy (≥5 long-term medications). A subset of the Beers 2019 criteria was applied for the assessment of medication appropriateness.

RESULTS

Data from 300 patients were analysed. The mean age was 79.1 years (SD 5.7). 53% had at least one PIM (men: 47.8%%, women: 60.4%%; p = 0.007). A higher number of medications was associated with PIM use (p = 0.002). We found high willingness to deprescribe in both participants with and without PIM. Willingness to deprescribe was not associated with PIM use (p = 0.25), nor number of PIMs (p = 0.81).

CONCLUSION

The willingness of older adults with polypharmacy towards deprescribing was not associated with PIM use in this study. These results suggest that patients may not be aware if they are taking PIMs. This implies the need for raising patients' awareness about PIMs through education, especially in females, in order to implement deprescribing in daily practice.

Polypharmacy Reduction Strategies: Tips on Incorporating American Geriatrics Society Beers and Screening Tool of Older People's Prescriptions Criteria

There is no single definition of polypharmacy. Use of 5 or more medications commonly is used. An alternative, quantitative definition, such as use of more medications than clinically indicated or use of unnecessary or harmful prescribing, has been proposed. Protocols or algorithms to improve polypharmacy and prescribing in older adults have been developed. The American Geriatrics Society (AGS) Beers Criteria and Screening Tool of Older People's Prescriptions (STOPP) explicit criteria reflect elements that are common across protocols and algorithms. Concepts in AGS Beers and STOPP can be incorporated into polypharmacy reduction strategies to improve outcomes of care for older adults.

Potentially inappropriate medications in a sample of Portuguese nursing home residents: Does the choice of screening tools matter?

Background Potentially inappropriate medications (PIMs) are often found in high proportion among the elderly population. The STOPP criteria have been suggested to detect more PIMs in European elderly than the Beers criteria. Objective This study aimed to determine the prevalence of PIMs and potential prescribing omissions (PPOs) in a sample of Portuguese nursing homes residents. Setting Four elderly facilities in mainland Portugal Method A descriptive cross-sectional study was used. Elderly polypharmacy patients were included in the study and their medication (registered in patient clinical records) analysed using the Beers (2012 original version and 2008 version adapted to Portugal), STOPP (Screening Tool of Older Person's Prescriptions) and START (Screening Tool to Alert doctors to Right Treatment) criteria. Data were analysed using univariate and bivariate descriptive statistics, considering a confidence interval of 95 %.

MAIN OUTCOME MEASURES

Prevalence of PIMs and PPOs. Results The sample included 161 individuals, with a mean age of 84.7 years (SD = 6.35), 68.9 % being female. A total of 807 PIMs and 90 PPOs were identified through the application of the three set of criteria. The prevalence of PIMs using the most recent version of the Beers criteria was 85.1 and 42.1 % for independent and dependent of diagnosis, respectively. The Portuguese adaptation of this same tool indicated a lower prevalence of PIMs, 60.3 and 16.7 %, respectively. The prevalence of PIMs using the STOPP criteria was 75.4 %, whilst the prevalence of PPOs, using START, was 42.9 %. There were significant differences in the mean number of PIMs detected depending on the tool used. (p < 0.001). Conclusions The application of the studied criteria in an elderly sample enabled the identification of a notable amount of PIMs and PPOs, indicating there is room for improving the quality of care. The variation in prevalence indicates careful choice of the tool is a prerequisite for engaging in medication review. Using START/STOPP criteria enabled a more holistic approach to the quality of prescribing in the elderly, highlighting low levels of cardiovascular risk prevention and abuse of psychotropic drugs, aside with system failures largely preventable by electronic prescribing and alert generation.

Polytherapy and the risk of potentially inappropriate prescriptions (PIPs) among elderly and very elderly patients in three different settings (hospital, community, long-term care facilities) of the Friuli Venezia Giulia region, Italy: are the very elderly at higher risk of PIPs?

PURPOSE

The aim of this point-prevalence study was to assess the occurrence of polypharmacy and hyperpolypharmacy and the risk of potentially inappropriate prescriptions (PIPs) among elderly and very elderly patients in different health-care settings of the Friuli-Venezia Giulia region in the North-East of Italy.

METHODS

Prescription pattern of elderly (65-79 years) and very elderly (>79 years) patients in three different health-care settings [hospitals, general practitioners, and long-term care facilities (LTCFs)] was assessed in March 2014, and PIPs were assessed according to the Beers criteria. Other situations at potentially high risk were checked.

RESULTS

A total of 1582 patients (hospital, n = 528; outpatients, n = 527; nursing homes, n = 527) were included. Very elderly were more represented in hospitals (60.4%) and LTCFs (77.1%) than among general practitioners (37.6%). Polypharmacy and hyperpolypharmacy rates ranged 57.7-73.7% and 9.7-15.6%, respectively. The most frequently prescribed drugs were the proton pump inhibitors, whereas the most common PIPs resulted the benzodiazepines. Multinomial regression analysis showed that female sex, age > 79 years, hyperpolypharmacy, and chronic kidney disease were associated with the risk of having ≥2 PIPs. Two situations at high risk of PIPs not contemplated by the Beers criteria were recurrent in the study population and concerned the statins and metformin.

CONCLUSIONS

Polypharmacy and hyperpolypharmacy among elderly and very elderly are strictly associated with the risk of multiple PIPs. The findings offer the opportunity to remark that improvement of the knowledge of safe drug use is generally needed in aging societies and may become of utmost relevance among health-care workers operating in LTCFs.
