Potentially inappropriate medication among people with dementia: towards individualized decision-making

The Association of Dementia With Incident Adverse Drug Reactions in Hospitalized Older Adults

BACKGROUND

Older adults with dementia commonly receive multiple medications and have higher hospitalization rates, elevating the risk of potentially inappropriate prescribing and in-hospital adverse drug reactions (ADRs). There is limited evidence examining ADRs in older adults with dementia during hospitalization.

OBJECTIVES

Our aim was to assess the association between dementia and incidence of ADRs during hospitalization and to identify prevalent types of ADRs and medications linked to ADRs.

DESIGN

Secondary analysis of the SENATOR trial database, which was a randomized controlled trial of an intervention to reduce ADRs in older inpatients with multimorbidity.

SETTING AND PARTICIPANTS

A total of 1537 patients (47.2% females) with a mean age of 78.1 years were recruited from 6 European hospitals.

METHODS

Sociodemographic data, functional status, cognitive status, clinical information, and ADR-related outcomes were extracted from the SENATOR database. Inpatients with dementia were identified based on prior International Classification of Diseases, Tenth Revision (ICD-10), dementia diagnosis, receiving acetylcholinesterase inhibitors or memantine, or a Mini-Mental State Examination score ≤24 at admission without concurrent delirium.

RESULTS

Among participants, 392 (25.5%) were identified as having dementia. The proportion of patients with probable or certain incident in-hospital ADRs was similar between the groups with and without dementia (22.4% vs 25.4%, P > .05). However, in-hospital rates of probable or certain ADRs from 12 common categories were less frequently identified in patients with dementia compared to those without (19.4% vs 23%, P = .025). Major constipation (6.4% vs 9.9%, P = .03) and acute dyspepsia, nausea, or vomiting (2.8% vs 5%, P = .03) were less commonly observed ADRs in patients with dementia.

CONCLUSIONS AND IMPLICATIONS

We did not observe an increased risk of in-hospital ADRs among inpatients with dementia. However, ADRs related to the gastrointestinal tract and identified by subjective symptoms were less frequently identified in this group. This study lays the groundwork for developing new tools for ADR diagnosis for older patients with dementia.

Surgical Outcomes of Thyroidectomy in Geriatric Patients Aged 80 Years and Older: A Single-Center Retrospective Cohort Study

Background and Objectives: As the global aging population grows, the incidence of thyroidectomy in elderly patients is increasing. This study aimed to evaluate the surgical outcomes of thyroidectomy in patients aged 80 years and older. Materials and Methods: All patients aged 80 years and older who underwent thyroidectomies at our hospital between January 2015 and December 2022 were reviewed in this retrospective cohort study. Collected data consisted of patients' clinical characteristics, functional status, compression symptoms, preoperative assessments, perioperative outcomes, postoperative complications (such as bleeding events, recurrent laryngeal nerve injury, hypocalcemia), pathological findings, readmission, and follow-up outcomes. Results: Seventeen patients were included in this study, with female predominance (82.4%). The mean age was 85.6 ± 4.8 years. Fourteen patients (82.4%) exhibited compression-related symptoms as surgical indications. Based on pathological reports, patients were categorized into benign (12/17, 70.6%) and malignancy (5/17, 29.4%) groups. The benign group had a shorter operation time compared with the malignancy group (164.3 ± 32.0 min vs. 231.0 ± 79.1 min, p = 0.048). No major postoperative complications developed. The median postoperative follow-up duration was 28 months (range: 2-91 months). Thirteen patients (76.5%) were alive at the end of the study period. Conclusions: Despite potential age-related risks, thyroidectomy is feasible for carefully selected patients aged 80 years and older. It provides benefits not only in terms of oncological curative treatment but also in improving the quality of life, such as compressive symptoms and wound condition.

Polypharmacy, Potentially Inappropriate Medications, and Dysphagia in Older Inpatients: A Multi-Center Cohort Study

BACKGROUND

Although the relationship between medication status, symptomatology, and outcomes has been evaluated, data on the prevalence of polypharmacy and potentially inappropriate medications (PIMs) and the association of polypharmacy and PIMs with swallowing function during follow-up are limited among hospitalized patients aged ≥65 years with dysphagia.

METHODS

In this 19-center cohort study, we registered 467 inpatients aged ≥65 years and evaluated those with the Food Intake LEVEL Scale (FILS) scores ≤8 between November 2019 and March 2021. Polypharmacy was defined as prescribing ≥5 medications and PIMs were identified based on the 2023 Updated Beers Criteria. We applied a generalized linear regression model to examine the association of polypharmacy and PIMs with FILS score at discharge.

RESULTS

We analyzed 399 participants (median age, 83.0 years; males, 49.8%). The median follow-up was 51.0 days (interquartile range, 22.0-84.0 days). Polypharmacy and PIMs were present in 67.7% of and 56.1% of patients, respectively. After adjusting for covariates, neither polypharmacy (β = 0.05; 95% confidence interval [CI], -0.04-0.13, p=0.30) nor non-steroidal anti-inflammatory medications (β = 0.09; 95% CI, -0.02-0.19; p=0.10) were significantly associated with FILS score at discharge.

CONCLUSION

The results of this study indicated a high proportion of polypharmacy and PIMs among inpatients aged ≥65 years with dysphagia. Although these prescribed conditions were not significantly associated with swallowing function at discharge, our findings suggest the importance of regularly reviewing medications to ensure the appropriateness of prescriptions when managing older inpatients.

Supporting shared decision-making in medicines use with people living with dementia and their carers

Polypharmacy and inappropriate prescribing of psychotropic medicines are common among people living with dementia and pose considerable health risks. One way of addressing these issues is by involving the person and their carer in shared decision-making. This article discusses some of the issues related to polypharmacy and inappropriate prescribing in people living with dementia and examines the concept of shared decision-making in this context. The author details some practical aids that nurses and other healthcare professionals can use to engage people living with dementia and their carers in shared decision-making about medicines use.
