Potentially inappropriate prescribing in nursing home residents detected with the community pharmacist specific GheOP(3)S-tool

Development of a medication review tool for residents in Korean long-term care facilities

INTRODUCTION

Residents in long-term care facilities (LTCFs) are likely to suffer from drug-related problems, such as inappropriate polypharmacy and potential prescribing omissions due to multimorbidity and high-level frailty. Medication reviews are thus necessary to identify and resolve drug-related problems in LTCF residents. In this study, we aimed to develop a medication review tool for older adults in LTCFs in Korea.

METHODS

We did a systematic review to identify previously developed explicit criteria and devised preliminary potentially inappropriate medications (PIMs) list for the LTCF elderly from previous tools. Each item on this list was categorized into 23 underlying diseases/conditions, and the interventions necessary for each PIM were included. A two-round modified Delphi survey was performed sequentially for consensus evaluation of clinical appropriateness and feasibility of the list items by 12 experts (seven physicians in different specialties and five pharmacists specialized in geriatrics) and seven pharmacists, respectively.

RESULTS

We identified 22 existing tools and devised a preliminary PIM list including 100 items. Ninety-one items were derived from the two-round Delphi survey for clinical appropriateness. In the feasibility test, 77 items were integrated into the final medication review tool for the LTCF elderly. The final list was composed of items relating to PIMs in general (18), potential drug interactions (14), PIMs under specific diseases/conditions (26), a need for dose adjustment (2), and potential omissions (17).

CONCLUSIONS

We developed a disease-category-based explicit medication review tool for detecting PIM use for LTCF residents. This tool may be helpful in implementing medication review practices to assist pharmacists or physicians for the elderly in LTCFs. Further research is required to validate the effectiveness of our tool in clinical practice.

Ghent Older People's Prescriptions Community Pharmacy Screening (GheOP3S)-Tool Version 2: Update of a Tool to Detect Drug-Related Problems in Older People in Primary Care

Background

The Ghent Older People’s Prescriptions community Pharmacy Screening (GheOP³S)-tool was developed in 2016 as a screening tool to detect drug-related problems (DRPs) and to help in performing medication reviews in older people (≥ 65 years).

Objective

This study aimed to revise and update the GheOP³S-tool.

Methods

Users’ comments were collected to improve the usability and appropriateness of the original GheOP³S-tool, followed by a two-round modified Delphi process according to the RAND/UCLA appropriateness method. This included a literature review, a round zero meeting, a first written round (with 15 international and multidisciplinary experts) and a second face-to-face round (with 11 experts) to change, delete or add GheOP³S-criteria. An additional third round with 14 community pharmacists was organised to preserve criteria applicable in the current community pharmacy practice.

Results

The updated GheOP³S-tool consists of five lists of DRPs and a new addendum containing medications that should be avoided or used with caution in older people with reduced renal function. During the first two rounds, related criteria were grouped, 14 criteria were added and 17 criteria were deleted from the original tool. All criteria were deemed applicable in round 3. This led to a final tool (version 2) with 64 GheOP³S-criteria.

Conclusion

GheOP³S-criteria were revised and updated according to experts’ agreement on their clinical relevance and recent scientific evidence. Future studies should investigate the impact of pharmacist-led medication reviews with GheOP³S-tool version 2 on clinical, humanistic and economic outcomes in primary care.

Application of the GheOP3S-tool in nursing home residents: acceptance and implementation of pharmacist recommendations

Background and objective: The prevalence of potentially inappropriate prescribing (PIP) among nursing home (NH) residents is high. This study aimed to investigate the acceptance and implementation of pharmacist recommendations based on a screening tool for PIP, the Ghent Older People's Prescriptions community Pharmacy Screening (GheOP³S)-tool. Setting and method: Prospective observational study in NH residents (≥ 70 years, using ≥ 5 medications) with a 3-month follow-up period. A pharmacist screened the medication lists using the GheOP³S-tool and formulated recommendations to reduce PIP. The acceptance of recommendations discussed during face-to-face pharmacist-general practitioner (GP) meetings was recorded. Implementation was examined by comparing baseline and follow-up medication lists. A pre-post comparison of the number of chronic medications and GheOP³S-criteria; the anticholinergic and sedative burden quantified by the Drug Burden Index (DBI); and medication costs was performed. Results: Screening with the GheOP³S-tool resulted in 168 pharmacist recommendations for 50 NH residents, mainly to stop (78.0%) and to substitute (14.3%) medications. Ninety-three % (156/168) of recommendations were considered relevant. GPs acceptance rate was 44.9%. Fifty-four % of all accepted recommendations were implemented. At follow-up, the number of chronic medications (p = 0.007), and DBI scores (p = 0.004) significantly differed from baseline. There was no significant decrease in the number of GheOP³S-criteria (p = 0.075) and medication costs (p > 0.05). Conclusion: The acceptance and implementation of pharmacist recommendations were relatively low. Future studies should increase the involvement of patients and all health-care providers. Interdisciplinary collaboration with sufficient education for all disciplines and patients is essential.

GheOP3 S tool and START/STOPP criteria version 2 for screening of potentially inappropriate medications and omissions in nursing home residents

RATIONALE, AIMS, AND OBJECTIVE

There is limited information about the comparative effectiveness of the START/STOPP (Screening Tool of Older Person's Prescriptions/Screening Tool to Alert doctors to Right Treatment) criteria and the Ghent Older People's Prescriptions community Pharmacy Screening tool (GheOP³ S tool) for the screening of potentially inappropriate prescribing (PIP) in the geriatric population. Considering this, the aim of this study was to compare the ability of the START/STOPP criteria and GheOP³ S tool to identify the PIP and potential prescribing omissions (PPOs) among elderly patients visiting their primary care physician.

METHODS

This is a retrospective observational study where a total of 422 subjects were included. The Charlson Co-morbidity Index (CCI) and the Medicines Co-morbidity Index (MCI) for older people were used to determine the co-morbidity status. The user's diagnosis and medications prescribed were analysed with the START/STOPP criteria and GheOP³ S tool. The Wilcoxon signed rank test was used to compare these criteria. The statistical relationship between the occurrence of PIP and users' age, the number of medication prescribed, the number of diagnoses, CCI, and MCI was determined with one-tailed bivariate correlation.

RESULTS

The START/STOPP criteria detected 843 PIPs and 1067 PPOs, while the GheOP³ S tool detected 936 PIPs and 202 PPOs. The GheOP³ S tool detected significantly more PIPs than did the STOPP criteria (P = 0.003). A significantly higher number of PPOs were detected with the START criterion (P < 0.0001). The results obtained with the START/STOPP criteria positively correlated with mentioned variables. Oppositely, there is a negative correlation between the results obtained with the GheOP³ S tool and age. Still, the positive correlation could be found with the rest of the variables.

CONCLUSION

The results of this study indicate that both tested tools demonstrated efficiency to detect PIPs and PPOs. The GheOP³ S tool detected significantly more PIPs than did the STOPP criteria. On the other hand, the START criteria performed much better for the screening of PPOs.

Factors associated with potentially inappropriate medication use in community-dwelling older adults in the United States: a systematic review

OBJECTIVES

Potentially inappropriate medication (PIM) use in older adults is a prevalent problem associated with poor health outcomes. Understanding drivers of PIM use is essential for targeting interventions. This study systematically reviews the literature about the patient, clinician and environmental/system factors associated with PIM use in community-dwelling older adults in the United States.

METHODS

PRISMA guidelines were followed when completing this review. PubMed and EMBASE were queried from January 2006 to September 2017. Our search was limited to English-language studies conducted in the United States that assessed factors associated with PIM use in adults ≥65 years who were community-dwelling. Two independent reviewers screened titles and abstracts. Reviewers abstracted data sequentially and assessed risk of bias independently.

KEY FINDINGS

Twenty-two studies were included. Nineteen examined patient factors associated with PIM use. The most common statistically significant factors associated with PIM use were taking more medications, female sex, and higher outpatient and emergency department utilization. Only three studies examined clinician factors, and few were statistically significant. Fifteen studies examined system-level factors such as geographic region and health insurance. The most common statistically significant association was the south and west geographic region relative to the northeast United States.

CONCLUSIONS

Amongst older adults, women and persons on more medications are at higher risk of PIM use. There is evidence that increased healthcare use is also associated with PIM use. Future studies are needed exploring clinician factors, such as specialty, and their association with PIM prescribing.

Potentially inappropriate medication in the elderly: a systematic review of validated explicit criteria

PURPOSE

Potentially inappropriate medication (PIM) use causes preventable adverse drug reactions in older patients. Several assessment tools have been published to identify and avoid PIM use. In this systematic literature review, we aim to provide summaries and comparisons of validated PIMs lists published between 1991 and 2017 internationally.

METHODS

In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA), we performed a systematic review of articles describing the development and validation of criteria for identification of PIMs among older people published between January 1991 and April 2017. The searches were conducted on PUBMED, AgeLine, Academic Search, Academic Search Premier, and CINAHL. We identified the most common medications/classes described as PIM. We also identified the drug-disease interactions and drug-drug interactions reported among criteria.

RESULTS

From 2933 articles screened, 36 met our inclusion criteria. The majority used the Delphi method to validate their criteria. We identified 907 different medications/classes, 536 different drug disease interactions involving 84 diseases/conditions, and 159 drug-drug interactions. Benzodiazepines and nonsteroidal anti-inflammatory drugs were the medications most commonly reported as potentially inappropriate for older people.

CONCLUSION

Although approaches aimed at detecting inappropriate prescribing have intensified in recent years, we observed limited overlap between different PIM lists. Additionally, some PIM lists did not provide special considerations of use and alternative therapies to avoid PIMs. These facts may compromise the use of PIM lists in clinical practice. Future PIM lists should integrate information about alternative therapies and special considerations of use in order to help clinicians in the drug prescription.

Potentially inappropriate medication among people with dementia in eight European countries

Objectives

to evaluate the frequency of potentially inappropriate medication (PIM) prescription among older people with dementia (PwD) from eight countries participating in the European study 'RightTimePlaceCare', and to evaluate factors and adverse outcomes associated with PIM prescription.

Methods

survey of 2,004 PwD including a baseline assessment and follow-up after 3 months. Interviewers gathered data on age, sex, prescription of medication, cognitive status, functional status, comorbidity, setting and admission to hospital, fall-related injuries and mortality in the time between baseline and follow-up. The European Union(7)-PIM list was used to evaluate PIM prescription. Multivariate regression analysis was used to investigate factors and adverse outcomes associated with PIM prescription.

Results

overall, 60% of the participants had at least one PIM prescription and 26.4% at least two. The PIM therapeutic subgroups most frequently prescribed were psycholeptics (26% of all PIM prescriptions) and 'drugs for acid-related disorders' (21%). PwD who were 80 years and older, lived in institutional long-term care settings, had higher comorbidity and were more functionally impaired were at higher risk of being prescribed two PIM or more. The prescription of two or more PIM was associated with higher chance of suffering from at least one fall-related injury and at least one episode of hospitalisation in the time between baseline and follow-up.

Conclusions

PIM use among PwD is frequent and is associated with institutional long-term care, age, advanced morbidity and functional impairment. It also appears to be associated with adverse outcomes. Special attention should be paid to psycholeptics and drugs for acid-related disorders.
