Medicine optimization strategy in an acute geriatric unit: The pharmacist in the geriatric team

Assessment of a Geriatric Evaluation and Management in the Home (GEMITH) Service at a Quaternary Hospital: A Retrospective Observational Study

Background: The increasing aging population in Australia has created a higher demand for specialist geriatric services within hospitals. A Geriatric Evaluation and Management in the Home (GEMITH) service was implemented at a quaternary Queensland hospital. The GEMITH service was unique as it incorporated a specialist pharmacist into the multidisciplinary team. Objective: To determine the medication safety and quality impact of the GEMITH service by evaluating the type and clinical significance of specialist pharmacist interventions. Methods: This was retrospective observational study of clinical interventions made by the GEMITH pharmacist for patients admitted to the service between October 2020 to April 2021. All pharmacist interventions were rated for their clinical significance using the Society of Hospital Pharmacists of Australia (SHPA) risk classification system. The ratings were undertaken by a panel of three pharmacists that independently assessed the interventions, coming together for final discussion. A narrative analysis of the interventions were derived through group consensus. Results: There was a total of 119 admissions to the GEMITH service, with 132 clinical interventions made by the specialist geriatric pharmacist. The majority (47%) of interventions were considered as low risk interventions, although high- (21%) and extreme-risk (2%) interventions still occurred. The most common type of intervention (32%) involved medication reconciliation. Other intervention types included monitoring recommendations, dosing interventions, and deprescribing suggestions. Conclusion: Multiple clinical interventions were made by the GEMITH pharmacist, which prevented possible and significant medication-related harm. This demonstrated the quality impact of the specialist pharmacist in improving medication safety for geriatric patients.

The Impact of Pharmacist Medication Reviews on Geriatric Patients: A Scoping Review

Medication review is an intervention with the potential to reduce drug-related problems (DRPs) in the elderly. This study aimed to determine the effect of pharmacists' medication reviews on geriatric patients. This study accessed two online databases, MEDLINE Complete and Scopus, and examined all studies published in English between 2019 and 2023, except for reviews. The studies included (1) participants over 65 years of age and (2) medication reviews conducted by pharmacists. The titles, abstracts, and full texts were reviewed for data extraction to determine whether the studies satisfied the inclusion and exclusion criteria. Forty-four of the initial 709 articles were included in this study. The articles included discussions on the incidence rates of DRPs and potentially inappropriate medications (PIMs) (n=21), hospitalization (n=14), medication adherence (n=9), quality of life (QoL) (n=8), and falls (n=7). Pharmacist medication reviews were associated with a reduced incidence of DRPs and PIMs, and improved adherence to medications. Patients' overall QoL is also increasing. However, pharmacist medication reviews were not strongly associated with decreased hospitalization or falls. A pharmacist's medication review may be a feasible intervention for reducing the incidence rates of DRPs and PIMs, regardless of whether it is performed as a sole intervention or supplemented with other interventions. The intervention was also effective in increasing medication adherence and QoL.

Association between Cognitive Impairment Severity and Polypharmacy in Older Patients with Atrial Fibrillation: A Retrospective Study Using Inpatient Data from a Specialised Geriatric Hospital

This study aimed to investigate the association between cognitive impairment and polypharmacy in patients with atrial fibrillation prone to cognitive decline, and to elucidate if the Dementia Assessment Sheet for Community-based Integrated Care System 21-Items (DASC-21) severity classification indicates drug adjustment. This retrospective cohort study used the DASC-21 and Diagnosis Procedure Combination data at a specialised geriatric hospital with patients hospitalised between April 2019 and March 2022. The association between cognitive severity evaluated using the DASC-21 and polypharmacy was investigated using a multivariate logistic regression model. Data of 1191 inpatients (44.3% aged ≥85 years, 49.0% male) were analysed. Compared with severe cognitive impairment, mild (odds ratio [OR]: 3.33, 95% confidence interval [CI]: 1.29-8.57) and moderate (OR: 2.46, 95% CI: 1.06-5.72) impairments were associated with concurrent use of ≥6 medications. Antithrombotics were related to polypharmacy. The ORs did not change with 6, 8, or 10 medications (2.11 [95% CI: 1.51-2.95, p < 0.001], 2.42 [95% CI: 1.79-3.27, p < 0.001], and 2.01 [95% CI: 1.46-2.77, p < 0.001], respectively). DASC-21 severity was associated with polypharmacy in patients with atrial fibrillation, with a trend toward decreased polypharmacy from moderate to severe. The DASC-21 may serve as an indicator for drug adjustment in clinical practice.

Implementation of a clinical decision support system for the optimization of antidiabetic drug orders by pharmacists

AIMS

The objective of the study was to describe the impact of a clinical decision support system (CDSS) on antidiabetic drug management by clinical pharmacists for hospitalized patients with T2DM.

METHODS

We performed a retrospective, single-centre study in a teaching hospital, where clinical pharmacists analysed prescriptions and issued pharmacist interventions (PIs) through a computerized physician order entry (CPOE) system. A CDSS was integrated into the pharmacists' workflow in July 2019. We analysed PIs during 2 periods of interest: one before the introduction of the CDSS (from November 2018 to April 2019, PIs issued through the CPOE alone) and one afterwards (from November 2020 to April 2021, PIs issued through the CPOE and/or the CDSS). The study covered nondiabetology wards as endocrinology, diabetes and metabolism departments were not computerized at the time of the study.

RESULTS

There were 203 PIs related to antidiabetic drugs in period 1 and 319 in period 2 (a 57.5% increase). Sixty-four of the 319 PIs were generated by the CDSS. Noncompliance/contraindication was the main problem identified by the CDSS (41 PIs, 68.4%), and 57.8% led to discontinuation of the drug. Most of the PIs issued through the CDSS corresponded to orders that had not been flagged up by clinical pharmacists using the CPOE. Conversely, most alerts about indications that were not being treated were detected by the clinical pharmacists using the CPOE and not by the CDSS.

CONCLUSION

Use of CDSS by clinical pharmacists improved antidiabetic drug management for hospitalized patients with T2DM. The CDSS might add value to diabetes care in nondiabetology wards by decreasing the frequency of potentially inappropriate prescriptions and adverse drug reactions.

Cognitive and functional trajectories in geriatric outpatients after a pharmacologic multidisciplinary intervention: A study protocol

BACKGROUND

Polypharmacy is a common condition among older adults and is associated with adverse drug reactions and health outcomes, including falls, functional and cognitive impairment, and frailty.

METHODS

A prospective observational study will be conducted on older adults with polypharmacy. The aim is to assess the impact of a specialized outpatient clinic focused on pharmacotherapy optimization recently integrated into daily clinical practice in a Spanish public tertiary teaching hospital on patients' functional and cognitive abilities. Patients who attend a first consultation and meet inclusion criteria (≥75 years old, have a life expectancy≥3 months, and polypharmacy (≥5 prescribed medications) will be invited to participate in the study, until reach a calculated sample size of 104 participants. Patients will be excluded if they are enrolled in a clinical trial related to medication or in the event of a no-show or cancellation of the appointment at the first visit. Participants will receive usual care: a first consultation including multidisciplinary pharmacological optimization in the context of a CGA and subsequent face-to-face and/or telephone follow-up (∼3 and ∼6 months). The primary endpoint will be the functional (Barthel index) and cognitive change in capacities (IPCR - Índice de Incapacidad psíquica de la Cruz Roja). Secondary endpoints include medication changes, changes in patients' quality of life, rate of falling, and use of healthcare resources.

DISCUSSION

We expect that the close collaboration between professionals from different disciplines working together will be an effective strategy to improve the functional and cognitive abilities of older adults.

Research status and hotspots of medication safety in older adults: A bibliometric analysis

Background

Medication safety is a significant concern in healthcare. Research on medication safety for older adults has taken a broad approach, resulting in a range of proposals. At this juncture, it is necessary to identify the main contributors and establish the current developmental status of the principal research topics.

Objective

This study sets out to summarize the state-of-the-art in medication safety for older adults, identifying significant achievements, key topics, and emerging trends.

Methods

The Web of Science Core Collection (WOSCC) database was searched for relevant documentation over the interval 1st January 2000 to 31st December 2021. Annual outputs and citations were identified from the WOS citation reports. CiteSpace and VOSviewer were adopted for bibliometric analysis and visualization that included the distribution of countries/regions, organizations, authors and journals, and an analysis of co-cited references and keywords.

Results

A total of 1,638 documents were retrieved for bibliometric analysis, yielding 34.29 citations per document. Publications have increased over the past two decades, reaching 177 outputs in 2019. Our database encompasses 71 countries/regions, 2,347 organizations, and 7,040 authors. The United States ranks first in terms of scientific activity with 604 publications (36.87%). We have identified the University of Sydney as the most prolific organization (53 publications). J. T. Hanlon, J. H. Gurwitz, D. O'Mahony, and G. Onder are the most influential researchers in terms of publications and citations. The Journal of the American Geriatrics Society ranks first with 89 (5.43%) papers. In terms of major research directions, three topics have been identified from co-cited reference and keyword analysis: (1) estimation of the prevalence and variables associated with polypharmacy and potentially inappropriate medication; (2) analysis of interventions involving pharmacists and the associated impact; (3) patient experience and perception associated with medication use or pharmaceutical care.

Conclusion

Research on medication safety for older adults has progressed significantly over the past two decades. The United States, in particular, has made important contributions to this field. Polypharmacy and potentially inappropriate medication use, interventions involving pharmacists, patient experience and perception represent the current focus of research. Our findings suggest that these directions will continue as research hotspots in the future.

Bedside medication review with cognitive and depression screening by a clinical pharmacist as part of a comprehensive geriatric assessment in hospitalized older patients with polypharmacy: A pilot study

BACKGROUND

Polypharmacy is highly prevalent in older patients with multimorbidity and is associated with increased risk of adverse drug events. This pilot study investigated the added value of a bedside medication review with cognitive and depression screening by a clinical pharmacist to identify potentially inappropriate medications (PIMs) and medication use issues in older patients with polypharmacy.

METHODS AND RESULTS

In the period from September 2018 to March 2019, a clinical pharmacist took part in the comprehensive geriatric assessment of 37 older patients hospitalized at Antwerp University Hospital and conducted a medication review consisting of a record review, a bedside interview questionnaire covering medication use, evaluation of cognitive function (abbreviated MMSE), depression (GDS-4), and systematic check for possible PIMs (STOPP/START criteria). Patients were 83±4 years old and on a median of 12 home medications (range 5-20). The clinical pharmacist formulated an average of 7.7 recommendations to optimize medication use per patient, of which 89.9% were considered clinically relevant by the geriatrician. Only 2 out of 286 PIMs were discovered during routine electronic validation of medication prescriptions. Supervision of medication intake was absent in 75% of cognitively impaired patients, but advice to do so was implemented in 86.4% of cases. The multidisciplinary geriatric advice was communicated to the treating physician, who fully implemented 33.8% of the recommendations.

CONCLUSIONS

Bedside medication review with cognitive and depression screening by a clinical pharmacist is useful to discover polypharmacy related problems and medication intake issues in a population of geriatric patients. Systematic screening for cognitive impairment and depression are needed to detect patients in need of support for correct medication use and therapy compliance.

Influence of a ward-based pharmacist on the medication quality of geriatric inpatients: a before-after study

Background Despite several international studies demonstrating that ward-based pharmacists improve medication quality, ward pharmacists are not generally established in German hospitals. Aim We assessed the effect of a ward-based clinical pharmacist on the medication quality of geriatric inpatients in a German university hospital. Method The before-after study with a historic control group was conducted on the geriatric ward. During the control phase, patients received standard care without the involvement of a pharmacist. The intervention consisted of a clinical pharmacist providing pharmaceutical care from admission to discharge. Medication quality was measured on admission and discharge using the Medication Appropriateness Index (MAI). A linear regression analysis was conducted to calculate the influence of the intervention on the MAI. Results Patients in the intervention group (n = 152, mean 83 years) were older and took more drugs at admission compared to the control group (n = 159, 81 years). For both groups, the MAI per patient improved significantly from admission to discharge. Although the intervention did not influence the summated MAI score per patient, the intervention significantly reduced the MAI criteria Dosage (p = 0.006), Correct Directions (p = 0.016) and Practical Directions (p = 0.004) as well as the proportion of overall inappropriate MAI ratings (at least 1 of 9 criteria inappropriate) (p = 0.015). Conclusion Although medication quality was already high in the control group, a ward-based clinical pharmacist could contribute meaningfully to the medication quality on an acute geriatric ward.

Effectiveness of Interventions to Reduce Potentially Inappropriate Medication in Older Patients: A Systematic Review

Background: Age-related multiple comorbidities cause older adults to be prone to the use of potentially inappropriate medicines (PIM) resulting in an increased risk of adverse events. Several strategies have emerged to support PIM prescription, and a huge number of interventions to reduce PIM have been proposed. This work aims to analyze the effectiveness of PIM interventions directed to older adults.

Methods: A systematic review was performed searching the literature in the MEDLINE PubMed, EMBASE, and Cochrane scientific databases for interventional studies that assessed the PIM interventions in older adults (≥65 years).

Results: Forty-seven articles were included, involving 52 to 124,802 patients. Various types of interventions were analyzed such as medication review, educational strategies, clinical decision support system, and organizational and multifaceted approaches. In the hospital, the most successful intervention was medication review (75.0%), while in primary care, the analysis of all included studies revealed that educational strategies were the most effective. However, the analysis of interventions that have greater evidence by its design was inconclusive.

Conclusion: The results obtained in this work suggested that PIM-setting-directed interventions should be developed to promote the wellbeing of the patients through PIM reduction. Although the data obtained suggested that medication review was the most assertive strategy to decrease the number of PIM in the hospital setting, more studies are necessary.

Impact of the COVID-19 pandemic on drug-related problems and pharmacist interventions in geriatric acute care units

Objectives

To assess and compare the pharmaceutical analysis on drug management in a geriatric acute care unit prior to and during the COVID-19 pandemic.

Methods

This was a single-centre, retrospective, and comparative cohort study. All Pharmacist Interventions (PIs) carried out in the unit between 27 January 2020 and 30 April 2020 were distinguished according to whether they were conducted prior to or during the first wave of COVID-19. The main outcome measure was the rate of PIs per patient and per prescription lines analysed. Other data collected were the drug class managed by the PI, the Drug Related Problems (DRP) identified, the nature of the advice given, and the acceptance rate by geriatricians.

Results

A total of 355 patients were analysed, with PIs generated for 21.7% of the patients prior to COVID-19, and for 53.4% of the patients during the first wave (p < 0.001). Among the 4402 prescription lines analysed, 54 PIs were carried out for prescriptions prior to COVID-19, and 177 during the first wave (p = 0.002). DRPs were mostly related to anti-infectious drugs during the pandemic (20.3%, p = 0.038), and laxatives prior to the pandemic (13.0%, p = 0.023). The clinical impact of the PIs was mainly moderate (43.7%). The acceptance rate was 59.3%.

Conclusions

A greater amount of DRPs were detected and more therapeutic advice was proposed during the first wave of COVID-19, with a focus on drugs used for the management of COVID-19 rather than geriatric routine treatments. The needs for clinical pharmacists were strengthened during the pandemic.

Greater Changes in Drug Burden Index (DBI) during Hospitalization and Increased 30-Day Readmission Rates among Older In-Hospital Fallers

A higher drug burden index (DBI) is known to be associated with pre-admission falls leading to hospitalization. We investigated whether a mean difference in DBI (ΔDBI) between the events of in-hospital falls and hospital admission was associated with 30-day readmission in 113 patients ≥50 years who fell during their hospital stays between 2007 and 2014. A greater ΔDBI (≥0.09) was positively associated with higher 30-day readmission rates (incident rate ratio: 2.02; 95% confidence interval: 1.49-2.74). An effort to keep DBI low may thus decrease 30-day readmissions for older in-hospital fallers.
