Use of the EMPOWER brochure to deprescribe sedative-hypnotic drugs in older adults with mild cognitive impairment.

ABSTRACT: Evidence-based mailed educational brochures about the harms of sedative-hypnotic use lead to discontinuation of chronic benzodiazepine use in older adults. It remains unknown whether patients with mild cognitive impairment (MCI) are able to understand the information in the EMPOWER brochures, and whether they achieve similar rates of benzodiazepine discontinuation.Post-hoc analysis of the EMPOWER randomized, double-blind, wait-list controlled trial that assessed the effect of a direct-to-consumer educational intervention on benzodiazepine discontinuation. 303 community-dwelling chronic users of benzodiazepine medication aged 65-95 years were recruited from general community pharmacies in the original trial, 261 (86%) of which completed the trial extension phase. All participants of the control arm received the EMPOWER brochure during the trial extension. Normal cognition (n?=?139) or MCI (n?=?122) was determined during baseline cognitive testing using the Montreal Cognitive Assessment questionnaire. Changes in knowledge pre- and post-intervention were assessed with a knowledge questionnaire and changes in beliefs were calculated using the Beliefs about Medicines Questionnaire. Logistic regression was used to compare knowledge gained, change in beliefs and benzodiazepine cessation rates between participants with and without MCI.Complete discontinuation of benzodiazepines was achieved in 39 (32.0% [24.4,40.7]) participants with MCI and in 53 (38.1% [30.5,46.4]) with normal cognition (adjusted OR 0.79, 95% CI [0.45-1.38]). Compared to individuals with normal cognition, MCI had no effect on the acquisition of new knowledge, change in beliefs about benzodiazepines or elicitation of cognitive dissonance.The EMPOWER brochure is effective for reducing benzodiazepines in community-dwelling older adults with mild cognitive impairment.Our ClinicalTrials.gov identifier is NCT01148186 , June 21st 2010.

Project description:Studies have suggested that insulin resistance plays a role in cognitive impairment in individuals with type 2 diabetes. We aimed to determine whether an improvement in insulin resistance could explain cognitive performance variations over 36 weeks in older individuals with mild cognitive impairment (MCI) and type 2 diabetes.A total of 97 older individuals (mean +/- SD age 76 +/- 6 years) who had recently (<2 months) started an antidiabetes treatment of metformin (500 mg twice a day) (n = 30) or metformin (500 mg/day)+rosiglitazone (4 mg/day) (n = 32) or diet (n = 35) volunteered. The neuropsychological test battery consisted of the Mini-Mental State Examination (MMSE), Rey Verbal Auditory Learning Test (RAVLT) total recall, and Trail Making Tests (TMT-A and TMT-B) performed at baseline and every 12 weeks for 36 weeks along with clinical testing.At baseline, no significant differences were found between groups in clinical or neuropsychological parameters. Mean +/- SD values in the entire population were as follows: A1C 7.5 +/- 0.5%, fasting plasma glucose (FPG) 8.6 +/- 1.3 mmol/l, fasting plasma insulin (FPI) 148 +/- 74 pmol/l, MMSE 24.9 +/- 2.4, TMT-A 61.6 +/- 42.0, TMT-B 162.8 +/- 78.7, the difference between TMT-B and TMT-A [DIFFBA] 101.2 +/- 58.1, and RAVLT 24.3 +/- 2.1. At follow-up, ANOVA models tested changes in metabolic control parameters (FPI, FPG, and A1C). Such parameters improved in the metformin and metformin/rosiglitazone groups (P(trend) < 0.05 in both groups). ANCOVA repeated models showed that results for the metformin/rosiglitazone group remained stable for all neuropsychological tests, and results for the diet group remained stable for the MMSE and TMT-A and declined for the TMT-B (P(trend) = 0.024), executive efficiency (DIFFBA) (P(trend) = 0.026), and RAVLT memory test (P(trend) = 0.011). Results for the metformin group remained stable for the MMSE and TMTs but declined for the RAVLT (P(trend) = 0.011). With use of linear mixed-effects models, the interaction term, FPI x time, correlated with cognitive stability on the RAVLT in the metformin/rosiglitazone group (beta = -1.899; P = 0.009).Rosiglitazone may protect against cognitive decline in older individuals with type 2 diabetes and MCI.

Project description:BACKGROUND AND OBJECTIVES:Successful mechanisms for engaging patients in the deprescribing process remain unknown but may include: (1) triggering motivation to deprescribe by increasing patients' knowledge and concern about medications; (2) building capacity to taper by augmenting self-efficacy and (3) creating opportunities to discuss and receive support for deprescribing from a healthcare provider. We tested these mechanisms during theEliminating Medications through Patient Ownership of End Results (EMPOWER) () trial and investigated the contexts that led to positive and negative deprescribing outcomes. DESIGN:A realist evaluation using a sequential mixed methods approach, conducted alongside the EMPOWER randomised clinical trial. SETTING:Community, Quebec, Canada. PARTICIPANTS:261 older chronic benzodiazepine consumers, who received the EMPOWER intervention and had complete 6-month follow-up data. INTERVENTION:Mailed deprescribing brochure on benzodiazepines. MEASUREMENTS:Motivation (intent to discuss deprescribing; change in knowledge test score; change in beliefs about the risk-benefits of benzodiazepines, measured with the Beliefs about Medicines Questionnaire), capacity (self-efficacy for tapering) and opportunity (support from a physician or pharmacist). RESULTS:The intervention triggered the motivation to deprescribe among 167 (n=64%) participants (mean age 74.6 years±6.3, 72% women), demonstrated by improved knowledge (risk difference, 58.50% (95% CI 46.98% to 67.44%)) and increased concern about taking benzodiazepines (risk difference, 67.67% (95% CI 57.36% to 74.91%)). Those who attempted to taper exhibited increased self-efficacy (risk difference, 56.90% (95% CI 45.41% to 65.77%)). Contexts where the deprescribing mechanisms failed included lack of support from a healthcare provider, a focus on short-term quality of life, intolerance to withdrawal symptoms and perceived poor health. CONCLUSION:Deprescribing mechanisms that target patient motivation and capacity to deprescribe yield successful outcomes in contexts where healthcare providers are supportive, and patients do not have internal competing desires to remain on drug therapy.
