National Cohort Study of Homebound Persons Living With Dementia: Antibiotic Prescribing Trends and Opportunities for Antibiotic Stewardship.

Background: Over 7 million older Americans are homebound. Managing infections in homebound persons presents unique challenges that are magnified among persons living with dementia (PLWD). This work sought to characterize antibiotic use in a national cohort of PLWD who received home-based primary care (HBPC) through the Veterans Health Administration. Methods: Administrative data identified veterans aged ≥65 years with ≥2 physician home visits in a year between 2014 and 2018 and a dementia diagnosis 3 years before through 1 year after their initial HBPC visit. Antibiotics prescribed orally, intravenously, intramuscularly, or by enema within 3 days of an HBPC visit were assessed from the initial HBPC visit to death or December 31, 2018. Prescription fills and days of therapy (DOT) per 1000 days of home care (DOHC) were calculated. Results: Among 39 861 PLWD, the median age (interquartile range [IQR]) was 85 (78-90) years, and 15.0% were Black. Overall, 16 956 (42.5%) PLWD received 45 122 prescription fills. The antibiotic use rate was 20.7 DOT per 1000 DOHC. Telephone visits and advanced practice provider visits were associated with 30.9% and 42.0% of fills, respectively. Sixty-seven percent of fills were associated with diagnoses for conditions where antibiotics are not indicated. Quinolones were the most prescribed class (24.3% of fills). The overall median length of therapy (IQR) was 7 (7-10) days. Antibiotic use rates varied across regions. Within regions, the median annual antibiotic use rate decreased from 2014 to 2018. Conclusions: Antibiotic prescriptions were prevalent in HBPC. The scope, appropriateness, and harms of antibiotic use in homebound PLWD need further investigation.

Assessing an Interprofessional Polypharmacy and Deprescribing Educational Intervention for Primary Care Post-graduate Trainees: a Quantitative and Qualitative Evaluation.

BACKGROUND: Polypharmacy and potentially inappropriate medications (PIMs) are increasingly common and associated with adverse health effects. However, post-graduate education in polypharmacy and complex medication management for older adults remain limited. OBJECTIVE: The Initiative to Minimize Pharmaceutical Risk in Older Veterans (IMPROVE) polypharmacy clinic was created to provide a platform for teaching internal medicine (IM) and nurse practitioner (NP) residents about outpatient medication management and deprescribing for older adults. We aimed to assess residents' knowledge of polypharmacy and perceptions of this interprofessional education intervention. DESIGN: A prospective cohort study with an internal comparison group. PARTICIPANTS: IM residents and NP residents; Veterans ≥ 65 years and taking ≥ 10 medications. INTERVENTION: IMPROVE consists of a pre-clinic conference, shared medical appointment, individual appointment, and interprofessional precepting model. MAIN MEASURES: We assessed residents' performance on a pre-post knowledge test, residents' qualitative assessment of the educational impact of IMPROVE, and the number and type of medications discontinued or decreased. KEY RESULTS: The IMPROVE intervention group (n = 18) had a significantly greater improvement in test scores than the control group (n = 18) (14% ± 15% versus - 1.3% ± 16%) over a period of 6 months (Wilcoxon rank sum, p = 0.019). In focus groups, residents (n = 17) reported perceived improvements in knowledge and skills, noting that the experience changed their practice in other clinical settings. In addition, residents valued the unique interprofessional experience. Veterans (n = 71) had a median of 15 medications (IQR 12-19), and a median of 2 medications (IQR 1-3) was discontinued. Vitamins, supplements, and cardiovascular medications were the most commonly discontinued medications, and cardiovascular medications were the most commonly decreased in dose or frequency. CONCLUSIONS: Overall, IMPROVE is an effective model of post-graduate primary care training in complex medication management and deprescribing that improves residents' knowledge and skills, and is perceived by residents to influence their practice outside the program.

Religion, risk, and medical decision making at the end of life.

OBJECTIVE: The purpose of this study is to present empirical evidence about whether religious patients are more or less willing to undergo the risks associated with potentially life-sustaining treatment. METHODS: At least every 4 months 226 older community-dwelling persons with advanced cancer, congestive heart failure, or chronic obstructive pulmonary disease were asked questions about several dimensions of religiousness and about their willingness to accept potentially life-sustaining treatment. RESULTS: Results were mixed but persons who said that during their illness they grew closer to God (odds ratio [OR] = 1.79; 95% confidence intervals [CI] = 1.15, 2.78) or those grew spiritually (OR = 1.61; 95% CI = 1.03, 2.52) were more willing to accept risk associated with potentially life-sustaining treatment than were persons who did not report such growth. DISCUSSION: Not all dimensions of religiousness have the same association with willingness to undergo potentially life-sustaining treatment. Seriously ill older, religious patients are not especially predisposed to avoid risk and resist treatment.

The association between treatment preferences and trajectories of care at the end-of-life.

BACKGROUND: Honoring patients' treatment preferences is a key component of high-quality end-of-life care. OBJECTIVE: To determine the association of preferences with end-of-life care. DESIGN: Observational cohort study. PARTICIPANTS: 118 community-dwelling persons age > or = 65 years with advanced disease who died in a study which prospectively assessed treatment preferences. MEASUREMENTS: End-of-life care was categorized according to four pathways: (1) relief of symptoms only, (2) limited attempt to reverse acute process with rapid change to symptomatic relief, (3) more intensive attempt to reverse acute process with eventual change to symptomatic relief, and (4) highly intensive attempt to reverse acute process with no change in goal. RESULTS: Adjusting for diagnosis, those with greater willingness to undergo intensive treatment (defined as a desire for invasive therapies despite > or = 50% chance of death) were significantly more likely to receive care with an initial goal of life prolongation (pathways 2-4) [odds ratio 4.73 (95% confidence interval 1.39-16.08)] than those with lower willingness. Nonetheless, mismatches between preferences and pathways were frequent. Only 1 of 27 participants (4%) with lower willingness to undergo intensive treatment received highly intensive intervention (pathway 4); 53 of 91 participants (58%) with greater willingness to undergo intensive treatment received symptom control only (pathway 1). CONCLUSIONS: The association between preferences and trajectories of end-of-life care suggests that preferences are used to guide treatment decision-making. In contrast to concerns that patients are receiving unwanted aggressive care, mismatches between preferences and trajectories were more frequently in the direction of patients receiving less aggressive care than they are willing to undergo.
