Impact of low-value medications on quality of life, hospitalization and costs - A longitudinal analysis of patients living with dementia. Alzheimers Dement 2023; 19:4520-4531. [PMID: 36905286 DOI: 10.1002/alz.13012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 01/19/2023] [Accepted: 01/22/2023] [Indexed: 03/12/2023]
Abstract
INTRODUCTION This study aimed to analyze the impact of low-value medications (Lvm), that is, medications unlikely to benefit patients but to cause harm, on patient-centered outcomes over 24 months. METHODS This longitudinal analysis was based on baseline, 12 and 24 months follow-up data of 352 patients with dementia. The impact of Lvm on health-related quality of life (HRQoL), hospitalizations, and health care costs were assessed using multiple panel-specific regression models. RESULTS Over 24 months, 182 patients (52%) received Lvm at least once and 56 (16%) continuously. Lvm significantly increased the risk of hospitalization by 49% (odds ratio, confidence interval [CI] 95% 1.06-2.09; p = 0.022), increased health care costs by €6810 (CI 95% -707€-14,27€; p = 0.076), and reduced patients' HRQoL (b = -1.55; CI 95% -2.76 to -0.35; p = 0.011). DISCUSSION More than every second patient received Lvm, negatively impacting patient-reported HRQoL, hospitalizations, and costs. Innovative approaches are needed to encourage prescribers to avoid and replace Lvm in dementia care. HIGHLIGHTS Over 24 months, more than every second patient received low-value medications (Lvm). Lvm negatively impact physical, psychological, and financial outcomes. Appropriate measures are needed to change prescription behaviors.

Abstract
BACKGROUND AND OBJECTIVE The prevalence of dementia is increasing, while new opportunities for diagnosing, treating and possibly preventing Alzheimer's disease and other dementia disorders are placing focus on the need for accurate estimates of costs in dementia. Considerable methodological heterogeneity creates challenges for synthesising the existing literature. This study aimed to estimate the costs for persons with dementia in Europe, disaggregated into cost components and informative patient subgroups. METHODS We conducted an updated literature review searching PubMed, Embase and Web of Science for studies published from 2008 to July 2021 reporting empirically based cost estimates for persons with dementia in European countries. We excluded highly selective or otherwise biased reports, and used a random-effects meta-analysis to produce estimates of mean costs of care across five European regions. RESULTS Based on 113 studies from 17 European countries, the estimated mean costs for all patients by region were highest in the British Isles (73,712 EUR), followed by the Nordics (43,767 EUR), Southern (35,866 EUR), Western (38,249 EUR), and Eastern Europe and Baltics (7938 EUR). Costs increased with disease severity, and the distribution of costs over informal and formal care followed a North-South gradient with Southern Europe being most reliant on informal care. CONCLUSIONS To our knowledge, this study represents the most extensive meta-analysis of the cost for persons with dementia in Europe to date. Though there is considerable heterogeneity across studies, much of this is explained by identifiable factors. Further standardisation of methodology for capturing resource utilisation data may further improve comparability of future studies. The cost estimates presented here may be of value for cost-of-illness studies and economic evaluations of novel diagnostic technologies and therapies for Alzheimer's disease.

Translation of Collaborative Dementia Care Management into Different Healthcare Settings: Study Protocol for a Multicenter Implementation Trial (DCM:IMPact). J Alzheimers Dis Rep 2022; 6:617-626. [DOI: 10.3233/adr-220045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 08/04/2022] [Indexed: 11/06/2022] Open
Abstract
Background: Collaborative care models for people living with dementia (PwD) have been developed and evaluated, demonstrating safety, efficacy, and cost-effectiveness. However, these studies are based on heterogeneous study populations and primary care settings, limiting the generalizability of the results. Therefore, this study aims to implement and evaluate collaborative care across various healthcare settings and patient populations. Objective: To describe the study design of this multicenter implementation trial. Methods: This single-arm, multicenter, longitudinal implementation study will be conducted in five different healthcare settings, including 1) physicians’ networks, 2) dementia networks, 3) counselling centers, 4) hospitals, and 5) ambulatory care services. Eligibility criteria are: having a formal dementia diagnosis or having been screened positive for dementia and living community-dwelling. The staff of each healthcare setting identifies patients, informs them about the study, and invites them to participate. Participants will receive a baseline assessment followed by collaborative individualized dementia care management, comprising proven safe, effective, and cost-effective modules. Over six months, specially-qualified nurses will assess patients’ unmet needs, transfer them to individualized care plans, and address them, cooperating with various healthcare providers. A follow-up assessment is conducted six months after baseline. Approximately 60–100 PwD per setting per year are expected to participate. Differences across settings will be assessed regarding acceptability, demand, implementation success and barriers, efficacy, and cost-effectiveness. Results: We expect that acceptability, demand, implementation success and barriers, efficacy, and cost-effectiveness will vary by patients’ sociodemographic and clinical characteristics and unmet needs in each setting. Conclusion: The results will provide evidence highlighting differences in the implementation of collaborative care in various healthcare settings and demonstrating the settings with the highest need, best conditions for a successful implementation, and highest (cost-)effectiveness, as well as the population group that benefits most from collaborative care.

Recent Updates on Risk and Management Plans Associated with Polypharmacy in Older Population. Geriatrics (Basel) 2022; 7:geriatrics7050097. [PMID: 36136806 PMCID: PMC9498769 DOI: 10.3390/geriatrics7050097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 09/08/2022] [Accepted: 09/09/2022] [Indexed: 11/17/2022] Open
Abstract
The concept of polypharmacy encompasses adverse drug reactions and non-adherence factors in elderly individuals. It also leads to the increased use of healthcare services and negative health outcomes. The problem is further alleviated by the odds of potentially inappropriate medications (PIM), which lead to the development of drug-related problems. Since polypharmacy is more commonly observed in the elderly population, urgency is required to introduce operative protocols for preventing and managing this problem. The family medicine model of care can be associated with favorable illness outcomes regarding satisfaction with consultation, treatment adherence, self-management behaviors, adherence to medical advice, and healthcare utilization. Hence, interventions built on family medicine models can provide significant support in improving the outcomes of the older population and their quality of life. In this regard, the authors have taken up the task of explaining the accessible resources which can be availed to improve the application of health care services in the field of geriatric medicine.

Abstract
Background: Previous studies revealed that low-value medication (LvM), drugs that provide little or no benefit but have the potential to cause harm, are associated with hospitalizations in dementia. Recommended medications, referred to as high-value medication (HvM), can be used alternately. However, the effect of LvM and HvM on hospitalizations is uncertain. Objective: To determine the prevalence of LvM and HvM in hospitalized and non-hospitalized patients living with dementia (PwD) and the odds for hospital referrals in PwD receiving LvM or HvM. Methods: The analysis was based on 47,446 PwD who visited a general practitioner practice between 2017 and 2019. Different guidelines were used to elicit LvM and HvM, resulting in 185 LvM and HvM related recommendations. Of these, 117 recommendations (83 for LvM, 34 for HvM) were categorized into thirteen therapy classes. The association of hospital referrals issued by general practitioners and receiving LvM or HvM was assessed using multiple logistic regression models. Results: 20.4% of PWD received LvM. Most frequently prescribed LvM were non-recommended sedatives and hypnotics, analgesics, and antidepressants. Recommended HvM were 3.4 (69.9%) more frequently prescribed than LvM. Most commonly prescribed HvM were recommended antihypertensives, antiplatelet agents, and antiarrhythmics. Both receiving LvM and receiving HvM were associated with higher odds for hospital referrals. When receiving LvM were compared to HvM, no significant differences could be found in hospital referrals. Conclusion: LvM is highly prevalent but did not cause more likely hospital referrals than HvM. Further research should focus on acute hospitalizations, not only on planned hospital referrals.

Abstract
BACKGROUND Low-value medications (Lvm) provide little or no benefit to patients, may be harmful, and waste healthcare resources and costs. Although evidence from the literature indicates that Lvm is highly prevalent in dementia, evidence about the financial consequences of Lvm in dementia is limited. This study analyzed the association between receiving Lvm and healthcare costs from a public payers' perspective. METHODS This analysis is based on data of 516 community-dwelling people living with dementia (PwD). Fourteen Lvm were extracted from dementia-specific guidelines, the German equivalent of the Choosing Wisely campaign, and the PRISCUS list. Healthcare utilization was retrospectively assessed via face-to-face interviews with caregivers and monetarized by standardized unit costs. Associations between Lvm and healthcare costs were analyzed using multiple linear regression models. RESULTS Every third patient (n = 159, 31%) received Lvm. Low-value antiphlogistics, analgesics, anti-dementia drugs, sedatives and hypnotics, and antidepressants alone accounted for 77% of prescribed Lvm. PwD who received Lvm were significantly less cognitively impaired than those not receiving Lvm. Receiving Lvm was associated with higher medical care costs (b = 2959 €; 95% CI 1136-4783; p = 0.001), particularly due to higher hospitalization (b = 1911 €; 95% CI 376-3443; p = 0.015) and medication costs (b = 905 €; 95% CI 454-1357; p < 0.001). CONCLUSION Lvm were prevalent, more likely occurring in the early stages of dementia, and cause financial harm for payers due to higher direct medical care costs. Further research is required to derive measures to prevent cost-driving Lvm in primary care, that is, implementing deprescribing interventions and moving health expenditures towards higher value resource use.

Abstract
(1) Background: An aging society is frequently affected by multimorbidity and polypharmacy, which, in turn, leads to an increased risk for drug interaction. The aim of this study was to evaluate the influence of drug interactions on the length of stay (LOS) in hospitals. (2) Methods: This retrospective, single-centre study is based on patients treated for community-acquired pneumonia in the hospital. Negative binomial regression was used to analyse the association between drug interactions and the LOS in the hospital. (3) Results: The total cohort contained 503 patients, yet 46 inpatients (9%) that died were not included in the analyses. The mean age was 74 (±15.3) years, 35% of patients older than 65 years were found to have more than two drug interactions, and 55% had a moderate, severe, or contraindicated adverse drug reaction. The regression model revealed a significant association between the number of drug interactions (rate ratio (RR) 1.02; 95%-CI 1.01–1.04) and the severity of drug interactions (RR 1.22; 95%-CI 1.09–1.37) on the LOS for the overall cohort as well as for the subgroup of patients aged 80 years and older. (4) Conclusion: Drug interactions are an independent risk factor for prolonged hospitalisation. Standardised assessment tools to avoid drug interactions should be implemented in clinical routines.

Abstract
Background: Low-value care (LvC) is defined as care unlikely to provide a benefit to the patient regarding the patient’s preferences, potential harms, costs, or available alternatives. Avoiding LvC and promoting recommended evidence-based treatments, referred to as high-value care (HvC), could improve patient-reported outcomes for people living with dementia (PwD). Objective: This study aims to determine the prevalence of LvC and HvC in dementia and the associations of LvC and HvC with patients’ quality of life and hospitalization. Methods: The analysis was based on data of the DelpHi trial and included 516 PwD. Dementia-specific guidelines, the “Choosing Wisely” campaign and the PRISCUS list were used to indicate LvC and HvC treatments, resulting in 347 LvC and HvC related recommendations. Of these, 77 recommendations (51 for LvC, 26 for HvC) were measured within the DelpHi-trial and finally used for this analysis. The association of LvC and HvC treatments with PwD health-related quality of life (HRQoL) and hospitalization was assessed using multiple regression models. Results: LvC was highly prevalent in PwD (31%). PwD receiving LvC had a significantly lower quality of life (b = –0.07; 95% CI –0.14 – –0.01) and were significantly more likely to be hospitalized (OR = 2.06; 95% CI 1.26–3.39). Different HvC treatments were associated with both positive and negative changes in HRQoL. Conclusion: LvC could cause adverse outcomes and should be identified as early as possible and tried to be replaced. Future research should examine innovative models of care or treatment pathways supporting the identification and replacement of LvC in dementia.
