BACKGROUND: Promoting appropriate pharmacotherapy requires understanding the factors that influence how clinicians prescribe medications. While prior work has focused on patient and clinician factors, features of the organizational setting have received less attention, though identifying sources of variation in prescribing may help identify opportunities to improve patient safety and outcomes. OBJECTIVE: To evaluate the relationship between the number of clinicians who prescribe medications in a facility and facility prescribing intensity of six individual medication classes by clinician specialty: benzodiazepines, antipsychotics, antiepileptics, and antidepressants by psychiatrists and antibiotics, opioids, antiepileptics, and antidepressants by primary care clinicians (PCPs). DESIGN: We used 2017 Veterans Health Administration (VHA) administrative data. SUBJECTS: We included patient-clinician dyads of older patients (> 55 years) with an outpatient encounter with a clinician in 2017. Patient-clinician data from 140 VHA facilities were included (n = 13,347,658). Analysis was repeated for years 2014 to 2016. MAIN MEASURES: For each medication, facility prescribing intensity measures were calculated as clinician prescribing intensity averaged over all clinicians at each facility. Clinician prescribing intensity measures included percentage of each clinician's patients prescribed the medication and mean number of days supply per patient among all patients of each clinician. KEY RESULTS: As the number of prescribing clinicians in a facility increased, the intensity of prescribing decreased. Every increase of 10 facility clinicians was associated with a significant decline in prescribing intensity for both specialties for different medication classes: for psychiatrists, declines ranged from 6 to 11%, and for PCPs, from 2 to 3%. The pattern of more clinicians less prescribing was significant across all years. CONCLUSION: Future work should explore the mechanisms that link the number of facility clinicians with prescribing intensity for benzodiazepines, antipsychotics, antiepileptics, antidepressants, antibiotics, and opioids. Facilities with fewer clinicians may need additional resources to avoid unwanted prescribing of potentially harmful or unnecessary medications.

BACKGROUND: Little is known about patients' experiences with benzodiazepine (BZD) discontinuation, which is thought to be challenging given the physiological and psychological dependence and accompanying potential for significant withdrawal symptoms. The marked decline in BZD prescribing over the past decade in the US Department of Veterans Affairs healthcare system presents an important opportunity to examine the experience of BZD discontinuation among long-term users. OBJECTIVE: Examine the experience of BZD discontinuation among individuals prescribed long-term BZD treatment to identify factors that contributed to successful discontinuation. DESIGN: Descriptive qualitative analysis of semi-structured interviews conducted between April and December of 2020. PARTICIPANTS: A total of 21 Veterans who had been prescribed long-term BZD pharmacotherapy (i.e., > 120 days of exposure in a 12-month period) and had their BZD discontinued. APPROACH: We conducted semi-structured interviews with Veteran participants to learn about their BZD use and the process of discontinuation, with interviews recorded and transcribed verbatim. Data were deductively and inductively coded and coded text entered into a matrix to identify factors that contributed to successful BZD discontinuation. KEY RESULTS: The mean age of interview participants was 63.0 years (standard deviation 3.9); 94.2% were male and 76.2% were white. Of 21 participants, only 1 had resumed BZD treatment (prescribed by a non-VA clinician). Three main factors influenced success with discontinuation: (1) participants' attitudes toward BZDs (e.g., risks of long-term use, perceived lack of efficacy, potential for dependence); (2) limited withdrawal symptoms; and (3) effective alternatives, either from their clinician (e.g., medication, psychotherapy) or identified by participants. CONCLUSIONS: BZD discontinuation after long-term use is relatively well tolerated, and participants appreciated reducing their medication exposure, particularly to one associated with physical dependence. These findings may help reduce both patient and clinician anxiety related to BZD discontinuation.

Importance: There is interest in reducing long-term benzodiazepine prescribing given harms associated with use, but the cumulative risks or benefits of discontinuation are unknown. Objective: To identify the association of benzodiazepine discontinuation with mortality and other adverse events among patients prescribed stable long-term benzodiazepine therapy, stratified by baseline opioid exposure. Design, Setting, and Participants: This comparative effectiveness study with a trial emulation approach included data from a US commercial insurance database between January 1, 2013, and December 31, 2017. Eligible participants were adults with stable long-term benzodiazepine prescription treatment. Data were analyzed between December 2022 and November 2023. Exposure: Benzodiazepine discontinuation, defined as no benzodiazepine prescription coverage for 31 consecutive days identified during a 6-month grace period after baseline. Main Outcome and Measures: Mortality during 12 months of follow-up; secondary outcomes included nonfatal overdose, suicide attempt or self-inflicted injury, suicidal ideation, and emergency department use, identified in medical claims. Inverse probability weighting was used to adjust for baseline confounders that potentially affected treatment assignment and censoring due to death or disenrollment. Primary analysis used an intention-to-treat approach; a secondary per-protocol analysis estimated associations after accounting for nonadherence. Analyses were stratified by opioid use. Results: The study included 213â¯011 (136â¯609 female [64.1%]; mean [SD] age, 62.2 [14.9] years; 2953 Asian [1.4%], 18â¯926 Black [8.9%], 22â¯734 Hispanic [10.7%], and 168â¯398 White [60.2%]) and 140â¯565 (91â¯811 female [65.3%]; mean [SD] age, 61.1 [13.2] years; 1319 Asian [0.9%], 15â¯945 Black [11.3%], 11â¯989 Hispanic [8.5%], and 111â¯312 White [79.2%]) patients with stable long-term benzodiazepine use without and with opioid exposure, respectively. Among the nonopioid exposed, the adjusted cumulative incidence of death after 1 year was 5.5% (95% CI, 5.4%-5.8%) for discontinuers, an absolute risk difference of 2.1 percentage points (95% CI, 1.9-2.3 percentage points) higher than for nondiscontinuers. The mortality risk was 1.6 (95% CI, 1.6-1.7) times that of nondiscontinuers. Among those with opioid exposure, the adjusted cumulative incidence of death was 6.3% (95% CI, 6.0%-6.6%) for discontinuers, an absolute risk difference of 2.4 percentage points (95% CI, 2.2-2.7 percentage points) higher than for nondiscontinuers and a mortality risk 1.6 (95% CI, 1.5-1.7) times that of nondiscontinuers. Cumulative incidence of secondary outcomes was also higher among discontinuers. Conclusions and Relevance: This study identifies small absolute increases in risk of harms among patients with stable long-term prescription benzodiazepine treatment who appear to discontinue relative to continuing treatment, including those with and without recent prescription opioid exposure. Policy broadly promoting benzodiazepine discontinuation may have unintended risks.

BACKGROUND: Drug overdose (OD) deaths in the U.S. continue to rise. After opioids, benzodiazepines (BZD) are the medication most commonly involved in prescription overdoses, yet OD risk factors among those prescribed BZD are not well understood. Our objective was to examine characteristics of BZD, opioid, and other psychotropic prescriptions associated with increased drug OD risk following a BZD prescription. METHODS: We completed a retrospective cohort study using a 20% sample of Medicare beneficiaries with prescription drug coverage. We identified patients with a BZD prescription ("index") claim between 1 April 2016 and 31 December 2017. In the 6 months pre-index, those without and with BZD claims comprised incident and continuing cohorts, which were split by age (incident < 65 [n = 105,737], 65 + [n = 385,951]; continuing < 65 [n = 240,358], 65 + [n = 508,230]). Exposures of interest were: average daily dose and days prescribed of the index BZD; baseline BZD medication possession ratio (MPR) for the continuing cohort; co-prescribed opioids and psychotropics. Our primary outcome was a treated drug OD event (including accidental, intentional, undetermined, or adverse effect) within 30 days of the index BZD, examined using Cox proportional hazards. RESULTS: Among incident and continuing BZD cohorts, 0.78% and 0.56% experienced an OD event. Compared to 14-30 days, a < 14-day fill corresponded to higher OD risk in incident (< 65 adjusted hazard ratio [aHR] 1.16 [95% CI 1.03-1.31]; 65 + : aHR 1.21 [CI 1.13-1.30]) and continuing (< 65: aHR 1.33 [CI 1.15-1.53]; 65 + : aHR 1.43 [CI 1.30-1.57]) cohorts. Among continuing users, lower baseline exposure (i.e., MPR < 0.5) was associated with increased OD risk for those < 65 (aHR 1.20 [CI 1.06-1.36]); 65 + (aHR 1.12 [CI 1.01-1.24]). Along with opioids, concurrent antipsychotic use and antiepileptic use were associated with elevated risk of OD in all 4 cohorts (e.g., aHRs for the continuing 65 + cohort: opioid, 1.73 [CI 1.58-1.90]; antipsychotic, 1.33 [CI 1.18-1.50]; antiepileptic, 1.18 [1.08-1.30]). CONCLUSIONS: In both the incident and continuing cohorts, patients dispensed fewer days' supply were at increased OD risk; those in the continuing cohort with more limited baseline BZD exposure were also at elevated risk. Concurrent medication exposures including opioids, antipsychotics, and antiepileptics were associated with short-term elevated OD risk.

OBJECTIVES: Federal initiatives have been successful in reducing antipsychotic exposure in nursing home residents with dementia. We assessed if these initiatives were implemented equally across racial and ethnic minority groups. DESIGN: Retrospective, cross-sectional trends study. SETTING AND PARTICIPANTS: National long-stay nursing home residents with dementia from 2011 to 2017. METHODS: We examined trends in psychotropic drug class exposures from the Minimum Data Set assessments for non-Hispanic Black (NHB), Hispanic, and non-Hispanic White (NHW) residents using interrupted time-series analyses with age-sex standardized quarterly outcomes and time points to denote the National Partnership (2012) and Five Star Rating changes (2015). RESULTS: Initially, antipsychotic (33.0%) and sedative (6.8%) exposure was highest for Hispanic residents; antidepressant (59.8%) and anxiolytic (23.4%) exposure was highest for NHW residents; NHB residents had the lowest use of each. Antipsychotic use dropped at the time of the Partnership (ß = -0.8807, P = .0023) and the slope declined further after the Partnership (ß = -0.6611, P < .0001) for NHW. In comparison to NHW, the level and slope changes for NHB and Hispanics were not significantly different. The Five Star Rating change did not impact the level of antipsychotic use (ß = 0.027, P = .9467), but the slope changed to indicate a slowed rate of decline (ß = 0.1317, P = .4075) for NHW. As to the other psychotropic drug classes, there were few significant differences between trends seen in the racial and ethnic subgroups. The following exceptions were noted: antidepressant use decreased at a faster rate for NHB residents post-Partnership (ß = -0.1485, P = .0371), and after the Five Star Rating change, NHB residents (ß = -0.0428, P = .0312) and Hispanic residents (ß = -0.0834, P < .0001) saw antidepressant use decrease faster than NHW. Sedative use in slope post-Partnership period (ß = -0.086, P = .0275) and post-Five Star Rating (ß = -0.0775, P < .0001) declined faster among Hispanic residents. CONCLUSIONS AND IMPLICATIONS: We found little evidence of clinically meaningful differences in changes to 4 classes of psychotropic medication use among racial and ethnic minority nursing home residents with dementia following 2 major federal initiatives.

BACKGROUND: Benzodiazepine and antipsychotic medications are routinely prescribed for symptom management in hospice patients, but have significant risks for older adults. We explored the extent to which patient and hospice agency characteristics are associated with variations in their prescribing. METHODS: Cross-sectional analysis of hospice-enrolled Medicare beneficiaries aged ≥65 years in 2017 (N = 1,393,622 in 4219 hospice agencies). The main outcome was the hospice agency-level rate of enrollees with benzodiazepine and antipsychotic prescription fills divided into quintiles. Rate ratios were used to compare the agencies with the highest and lowest prescription across patient and agency characteristics. RESULTS: In 2017, hospice agency prescribing rates varied widely: for benzodiazepines, from a median of 11.9% (IQR 5.9,22.2) in the lowest-prescribing quintile to 80.0% (IQR 76.9,84.2) in the highest-prescribing quintile; for antipsychotics, it ranged from 5.5% (IQR 2.9,7.7) in the lowest to 63.9% (IQR 56.1,72.0) in the highest. Among the highest benzodiazepine- and antipsychotic- prescribing hospice agencies, there was a smaller proportion of patients from minoritized populations (benzodiazepine: non-Hispanic Black rate ratio [RR] [Q5/Q1] 0.7, 95% CI 0.6-0.7, Hispanic RR 0.4, 95% CI 0.3-0.5; antipsychotic: non-Hispanic Black RR 0.7, 95% CI 0.6-0.8, Hispanic RR 0.4, 95% CI 0.3-0.5). A greater proportion of rural beneficiaries were in the highest benzodiazepine-prescribing quintile (RR 1.3, 95% CI 1.2-1.4), whereas this relationship was not present for antipsychotics. Larger hospice agencies were over-represented in the highest prescribing quintile for both benzodiazepines (RR 2.6, 95% CI 2.5-2.7) and antipsychotics (RR 2.7, 95% CI 2.6-2.8), as were for-profit agencies (benzodiazepine: RR 2.4, 95% CI 2.3-2.4; antipsychotic: RR 2.3, 95% CI 2.2-2.4). Prescribing rates varied widely across Census regions. CONCLUSIONS: Prescribing in hospice settings varies markedly across factors other than the clinical characteristics of enrolled patients.

OBJECTIVES: Caregivers are typically enmeshed in networks of family and friends who assist with care, yet this network is largely neglected in research. In light of the fact that caregivers are key medical decision makers and play a critical role in how persons living with dementia (PLwDs) interface with the health care system, this study explores how features of the caregiver network relate to PLwD emergency department (ED) use. METHODS: Using 2015 National Health and Aging Trends Study data linked with fee-for-service Medicare claims, we examine ED use in a nationally representative sample of community-dwelling persons aged 65 and older with dementia and at least 1 caregiver. We consider aspects of the caregiver network including membership (e.g., daughter in network), network size, hours of care received, and the presence of generalists and specialists (i.e., broad vs narrow functional assistance) as predictors of ED encounters among PLwD. RESULTS: PLwDs were 81.5 years old on average, 50% were female, and 33% were non-White. Care networks including nonimmediate family members involved in task sharing for mobility and self-care difficulties and those with more generalists had significantly higher odds of an ED visit. Networks that only consisted of specialist caregivers had significantly lower odds of an ED visit. DISCUSSION: Greater complexity of care networks increases risk of presenting to the ED for care. Better understanding how caregiving networks help PLwD interact with the health care system can inform intervention design and targeting in order to help care networks improve care coordination, management, and shared decision making.

BACKGROUND: Antiepileptics are commonly prescribed to nursing home residents with Alzheimer's disease and related dementias (ADRD) but there is little scientific support for their use in this population. It is unclear whether different antiepileptics are targeting different indications. METHODS: Using the Minimum Data Set and Medicare data, including Part D pharmacy claims, we constructed annual cohorts of residents with ADRD with long-term stays in nursing homes from 2015 to 2019. For each year, we measured the proportion of residents with ADRD in nursing homes nationwide with at least one antiepileptic prescription. We also measured trends in valproic acid, gabapentin, antipsychotic, and opioid prescribing. Finally, we examined how prescribing rates differed based on whether residents with ADRD had disruptive behaviors or reported pain. RESULTS: Our study sample includes 973,074 persons living with ADRD who had a long-term stay in a nursing home, which was defined as at least 3 months. The proportion of residents with ADRD with at least one antiepileptic prescription increased from 29.5% in 2015 to 31.3% in 2019, which was driven by increases in the rate of valproic acid and gabapentin prescribing. Conversely, antipsychotic prescribing rates declined from 32.1% to 27.9% and opioid prescribing rates declined from 39.8% to 31.7%. The risk of valproic acid prescribing was 10.9 percentage points higher among residents with ADRD with disruptive behaviors, while the risk of being prescribed gabapentin was 13.9 percentage points higher among residents with ADRD reporting pain. CONCLUSIONS: Antiepileptic prescribing among nursing home residents with ADRD is increasing, while antipsychotic and opioid prescribing is declining. Examining antiepileptic prescribing to residents with ADRD who had disruptive behaviors and/or reported pain suggests that two of the most common antiepileptics, valproic acid and gabapentin, are being used in clinically distinct ways. Antiepileptic prescribing of questionable risk-benefit for dementia care warrants further scrutiny.

In this pilot study, we used a Medicare sample to identify primary care clinicians who prescribed a benzodiazepine (BZD) in 2017 and surveyed a random sample (n = 100) about BZD prescribing. Among 61 respondents, 11.5% (SD 5.9) of their patient panels filled a BZD prescription. Patients of primary care clinicians who agreed that potential harms to long-term BZD users were low had a greater BZD fill risk relative to patients of disagreeing primary care clinicians (adjusted risk ratio 1.31; 95% CI, 1.01-1.7). We highlight the potential of using Medicare claims to sample clinicians. Using claims-based objective measures presents a new method to inform the development of behavior-change interventions.

BACKGROUND: Benzodiazepines (BZD) are widely prescribed to older adults despite their association with increased fall injury. Our aim is to better characterize risk-elevating factors among those prescribed BZD. METHODS: A retrospective cohort study using a 20% sample of Medicare beneficiaries with Part D prescription drug coverage. Patients with a BZD prescription ("index") between 1 April 2016 and 31 December 2017 contributed to incident (n=379,273) and continuing (n=509,634) cohorts based on prescriptions during a 6-month pre-index baseline. Exposures were index BZD average daily dose and days prescribed; baseline BZD medication possession ratio (MPR) (for the continuing cohort); and co-prescribed central nervous system-active medications. Outcome was a treated fall-related injury within 30 days post-index BZD, examined using Cox proportional hazards adjusting for demographic and clinical covariates and the dose prescribed. RESULTS: Among incident and continuing cohorts, 0.9% and 0.7% experienced fall injury within 30 days of index. In both cohorts, injury risk was elevated immediately post-index among those prescribed the lowest quantity: e.g., for <14-day fill (ref: 14-30 days) in the incident cohort, risk was 37% higher the 10 days post-fill (adjusted hazard ratio [HR] 1.37 [95% confidence interval [CI] 1.19-1.59]). Risk was elevated immediately post-index for continuing users with low baseline BZD exposure (e.g., for MPR <0.5 [ref: MPR 0.5-1], HR during days 1-10 was 1.23 [CI 1.08-1.39]). Concurrent antipsychotics and opioids were associated with elevated injury risk in both cohorts (e.g., incident HRs 1.21 [CI 1.03-1.40] and 1.22 [CI 1.07-1.40], respectively; continuing HRs 1.23 [1.10-1.37] and 1.21 [1.11-1.33]). CONCLUSIONS: Low baseline BZD exposure and a small index prescription were associated with higher fall injury risk immediately after a BZD fill. Concurrent exposure to antipsychotics and opioids were associated with elevated short-term risk for both incident and continuing cohorts.

PURPOSE: Unlike in many community-based settings, benzodiazepine (BZD) prescribing to older veterans has decreased. We sought to identify health care system strategies associated with greater facility-level reductions in BZD prescribing to older adults. METHODS: We completed an explanatory sequential mixed methods study of health care facilities in the Veterans Health Administration (N = 140). Among veterans aged ≥75 years receiving long-term BZD treatment, we stratified facilities into relatively high and low performance on the basis of the reduction in average daily dose of prescribed BZD from October 1, 2015 to June 30, 2017. We then interviewed key facility informants (n = 21) who led local BZD reduction efforts (champions), representing 11 high-performing and 6 low-performing facilities. RESULTS: Across all facilities, the age-adjusted facility-level average daily dose in October 2015 began at 1.34 lorazepam-equivalent mg/d (SD 0.17); the average rate of decrease was -0.27 mg/d (SD 0.09) per year. All facilities interviewed, regardless of performance, used passive strategies primarily consisting of education regarding appropriate prescribing, alternatives, and identifying potential patients for discontinuation. In contrast, champions at high-performing facilities described leveraging ≥1 active strategies that included individualized recommendations, administrative barriers to prescribing, and performance measures to incentivize clinicians. CONCLUSIONS: Initiatives to reduce BZD prescribing to older adults that are primarily limited to passive strategies, such as education and patient identification, might have limited success. Clinicians might benefit from additional recommendations, support, and incentives to modify prescribing practices.

OBJECTIVES: We examined the association between nursing home (NH) characteristics and whether NHs had high or low levels of antipsychotic, benzodiazepine, or opioid prescribing to residents with Alzheimer's disease and related dementias (ADRD). We then measured the likelihood that NHs who were high (low) prescribers of antipsychotics were also high (low) prescribers of benzodiazepines or opioids. DESIGN: A retrospective, cross-sectional analysis. SETTING AND PARTICIPANTS: The sample included 448,128 Medicare beneficiaries diagnosed with ADRD, who resided in 13,151 NHs in 2017. METHODS: Using Medicare claims, the Minimum Data Set, and LTCFocus, we measured the share of NH residents with ADRD who filled ≥1 antipsychotic, benzodiazepine, or opioid prescription in 2017. Using linear probability models with state-clustered SEs, we identified which NH characteristics were associated with being in the top (bottom) quartile of the prescribing distribution for each drug class. Finally, we measured whether NHs who were top-quartile (bottom-quartile) antipsychotic prescribers were more likely to be top-quartile (bottom-quartile) benzodiazepine or opioid prescribers. RESULTS: Across NHs, an average of 29.1% of residents with ADRD received an antipsychotic, 30.2% received a benzodiazepine, and 40.9% received an opioid. Smaller NHs and NHs with a larger share of Medicaid-enrolled residents were more likely to be top-quartile prescribers; NHs with more registered nursing care were more likely to be bottom-quartile prescribers. Antipsychotic prescribing tracked closely with benzodiazepine prescribing, but not opioid prescribing. CONCLUSIONS AND IMPLICATIONS: The overlap between antipsychotic and benzodiazepine prescribing and our finding that some NH characteristics were consistently associated with prescribing across drug classes may support the idea of an organizational culture of prescribing in NHs, which could inform efforts to improve prescribing quality in NHs. Our results also highlight benzodiazepine and opioid use for ADRD, which were more commonly prescribed than antipsychotics in NHs but have received less regulatory attention.

OBJECTIVES: Electroconvulsive therapy (ECT) is a safe and effective procedure in unipolar depression in older adults; however, less is known about clinical features and trajectories among patients who do not respond. In this retrospective, naturalistic study, we examine characteristics associated with ECT response among older adults with unipolar depression who received ECT over an 8-year period and describe long-term outcomes for nonresponders. METHODS: We retrospectively identified patients 65 years or older with major depressive disorder who were treated with ECT during an 8-year period. We reviewed demographic and clinical factors among patients who responded to ECT and those who did not. Clinic notes were reviewed for ECT nonresponders to determine Clinical Global Impressions scores in the 24 months after ECT treatment. RESULTS: We identified 140 patients meeting the inclusion criteria. Most patients (65%) responded to ECT. Fewer previous antidepressant trials, lower baseline Montreal Cognitive Assessment scores, and lower baseline Montgomery-Asberg Depression Rating Scale scores were associated with an increased likelihood of ECT response. Among the 49 (35%) nonresponders, another 12 (24.5%) responded to a variety of treatments within 2 years after ECT. There were no serious adverse effects of treatment. CONCLUSIONS: Most patients responded to ECT, many of whom had severe illness that had been refractory to numerous medication trials. Among nonresponders, a subset improved over time through a variety of treatments. However, most patients who did not respond to ECT had persistent depression after 2 years.

BACKGROUND: Benzodiazepines and antipsychotics are routinely prescribed for symptom management in hospice. There is minimal evidence to guide prescribing in this population, and little is known about how prescribing varies across hospice agencies. OBJECTIVE: Examine patient- and hospice agency-level characteristics associated with incident prescribing of benzodiazepines and antipsychotics in hospice. DESIGN: Retrospective cohort study of a 20% sample of Medicare beneficiaries newly enrolled in hospice. PARTICIPANTS: Medicare hospice beneficiaries ≥ 65 years old between 2014 and 2016, restricted to those without benzodiazepine (N = 169,688) or antipsychotic (N = 190,441) prescription fills in the 6 months before hospice enrollment. MAIN MEASURES: The primary outcome was incident (i.e., new) prescribing of a benzodiazepine or antipsychotic. A series of multilevel Cox regression models with random intercepts for hospice agency were fit to examine the association of incident benzodiazepine and antipsychotic prescribing with patient and hospice agency characteristics. KEY RESULTS: A total of 91,728 (54.1%) and 58,175 (30.5%) hospice beneficiaries were newly prescribed an incident benzodiazepine or antipsychotic. The prescribing rate of the hospice agency was the strongest predictor of incident prescribing: Compared to patients in bottom-quartile benzodiazepine-prescribing agencies, those in top-quartile agencies were 10.7 times more likely to be prescribed an incident benzodiazepine (adjusted hazard ratio [AHR] 10.7, 95% CI 10.1-11.3). For incident antipsychotic prescribing, patients in top-quartile agencies were 51.7 times more likely to receive an antipsychotic (AHR 51.7, 95% CI 44.3-60.4) compared to those in the bottom quartile. Results remained consistent accounting for comfort kit prescribing. CONCLUSIONS: The pattern of benzodiazepine or antipsychotic prescribing of a hospice agency strongly predicts whether a hospice enrollee is prescribed these medications, exceeding every other patient-level factor. While the appropriate level of prescribing in hospice is unclear, this variation may reflect a strong local prescribing culture across individual hospice agencies.

Objectives: We examined the association between neighborhood characteristics and depressive symptoms in a population-based sample of dementia caregivers. Methods: Data came from the 2017 National Health and Aging Trends Study (NHATS) and National Study of Caregiving. The sample included 956 caregivers of those with dementia. Linear regression was used to examine associations between neighborhood physical disorder neighborhood social cohesion, and depressive symptoms, and to test the moderating effect of social support on these relations. Results: Results suggested that having friends and family (1) to talk to buffered the effect of high NPD and low cohesion on depressive symptoms, (2) to help with daily activities buffered the effect of low cohesion on depressive symptoms, and finally, and (3) to help with care had a protective effect on depressive symptoms if social cohesion was high. Discussion: Neighborhood contextual characteristics and social support interact to affect caregiver depressive symptoms in complex ways.

BACKGROUND: Spousal death is associated with elevated mortality in the surviving partner; less is known about how healthcare costs and use change following spousal death. OBJECTIVES: To examine the causal impact of spousal death on Medicare costs and use over time. DESIGN: Longitudinal cohort study with an event study design. SETTING: National Health and Aging Trends Study (NHATS) with linked Medicare claims. PARTICIPANTS: Respondents from 2011-2017 who reported spousal death the prior year, limited to those with traditional Medicare (n=491 with 9,766 respondent-quarters). MAIN MEASURES: Total Medicare costs; binary indicators for acute hospitalization; emergency department; sub-acute care (including skilled nursing, rehabilitation, and long-term care); and number of outpatient management visits on a quarterly basis 3 years before and after spousal death. KEY RESULTS: During the first year post-death, quarterly Medicare costs for the surviving spouse were $1,092 higher than pre-death; probability of hospitalization, emergency department, and sub-acute care were 3.3%, 2.8%, and 2.2% higher, respectively; and there were 0.3 more outpatient visits (p<.01 for all). Several outcomes continued to be elevated during the second year, including costs ($1,174 higher per quarter), hospitalization (3.2% higher), and sub-acute care (2.9% higher; p<.01 for all). By the third year, costs returned to pre-death level but hospitalization and sub-acute care (2.9% and 3.1% higher per quarter; p<.05 for both) remained elevated. Cost increases in the first and second years post-death were larger if the deceased spouse was a caregiver ($1,588 and $1,853 per quarter) or female (i.e., among bereaved males; $1,457 and $1,632 per quarter; p<.05 for all). CONCLUSIONS: Spousal death increased total Medicare costs and use of all healthcare categories among the surviving partner; elevations in hospitalization and sub-acute care persisted through the third year. Clinicians and payors may want to target surviving partners as a high-risk population.

BACKGROUND: Previous findings regarding the association between benzodiazepine exposure and dementia have conflicted, though many have not accounted for anticholinergic exposure. The goal of this study was to evaluate the association of benzodiazepine exposure with the risk of developing dementia, accounting for the anticholinergic burden. METHODS: Using a retrospective cohort design, we identified veterans 65 or older without dementia during a 10-year baseline period and then followed participants for 5 years to evaluate the risk of dementia diagnosis. The primary exposure was cumulative benzodiazepine exposure. Cox proportional hazards survival model was used to examine the association between benzodiazepine exposure and dementia, adjusting for anticholinergic burden and other demographic and clinical characteristics associated with increased dementia risk. RESULTS: Of the 528 006 veterans in the study cohort, 28.5% had at least one fill for a benzodiazepine. Overall, 7.9% developed a diagnosis of dementia during the observation period. Compared to veterans with no exposure to benzodiazepines, the adjusted hazard ratios for dementia risk were 1.06 (95% confidence interval [CI] 1.02-1.10) for low benzodiazepine exposure, 1.05 (95% CI 1.01-1.09) for medium benzodiazepine exposure, and 1.05 (95% CI 1.02-1.09) for high benzodiazepine exposure. CONCLUSIONS: Cumulative benzodiazepine exposure was minimally associated with increased dementia risk when compared with nonuse but did not increase in a dose-dependent fashion with higher exposure. Veterans with low benzodiazepine exposure had essentially the equivalent risk of developing dementia as veterans with high exposure. While benzodiazepines are associated with many side effects for older adults, higher cumulative use does not appear to increase dementia risk.
