A Propensity-Matched Cohort Assessing Impact of a Neutralizing Monoclonal Antibody in Mild-to-Moderate Coronavirus Disease 2019.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoaV-2) is responsible for the coronavirus disease 2019 (COVID-19) pandemic. In randomized clinical trials, patients who were treated with the anti-spike monoclonal antibody bamlanivimab had fewer COVID-19-related hospitalizations or emergency department (ED) visits than the control group. Methods: A retrospective cohort was assembled across a multisite healthcare system between November 20, 2020 and March 31, 2021. Ambulatory COVID-19 patients treated with bamlanivimab (n = 209) were propensity score matched without replacement (1:1) to a pool of 1024 eligible control patients who received similar care without bamlanivimab. The primary endpoint was all-cause mortality or admission at 30 days. Secondary endpoints included hospitalization, critical care admission, oxygenation requirements, and infusion-related reactions. Propensity score matching (PSM) analysis was used to assess the effect of bamlanivimab infusion on the composite endpoint and secondary endpoints. Results: A total of n = 209 matched patients were included in each arm of the study. The absolute standardized difference (stddiff) was calculated and indicated a balance between the groups. Almost all variables had a stddiff of less than 0.10, except for respiratory rate (RR) (stddiff = -0.11). For the primary composite endpoint of the matched cohort, 10.1% (n = 21) of patients in the intervention group were hospitalized or deceased within 30-day postbamlanivimab infusion versus 27.8% (n = 58) in the control group (adjusted odds ratio [aOR]: 0.29, 95% confidence interval [CI]: 0.17 to 0.51, P < .001). Conclusion: Patients with ambulatory COVID-19 who received bamlanivimab in the outpatient setting had a statistically significant reduction on the odds of admission postinfusion. Despite bamlanivimab's lack of efficacy on newer SARS-CoV-2 variants, this study demonstrates that neutralizing monoclonal antibodies can be effective against specific variants. If variant identification becomes a more accessible tool in outpatient centers or EDs, more targeted therapeutic options may be considered.

Prehospital Ketamine Use in Pediatrics.

Introduction: Information regarding prehospital ketamine use in the pediatric population is limited as existing literature focuses primarily on critical care and air transport. Our objective was to describe patient characteristics among pediatric EMS patients who received ketamine. Secondarily, we assessed effectiveness, deviation from recommended dosing, and adverse outcomes of pediatric EMS patients who received ketamine.Methods: We conducted a retrospective data review of records from the ESO Data Collaborative for all 9-1-1 transports of pediatric patients (≤ 18 years of age) who received ketamine from 2019-2020. We categorized EMS primary impressions as a proxy for medication indication. We defined effectiveness as paramedic-identified clinical improvement, and pain relief as decrease in pain score ≥2 points between initial and final recording. Descriptive statistics were used to summarize clinical characteristics. Non-parametric Wilcoxon signed-rank test was used to assess change in pain score.Results: Out of 422,968 ground-ambulance pediatric patients, 1,291 received ketamine. They were predominately male (842, 65.2%), teenagers (median age 16, IQR: 13-17), Caucasian (810, 62.7%), and from urban areas (1,041, 80.6%). The most common EMS impressions were related to injuries (810, 62.7%) and behavior disorders (281, 21.8%). Only 980/1,291 (75.9%) had weights and identifiable routes recorded. Most patients (960, 74.4%) received single doses of ketamine, with EMS clinicians reporting improvement in 855 (89.1%) of 960 patients. Among non-behavioral emergency patients, 727/1,010 (72.0%) had pain scores recorded. Pain scores decreased significantly from a median of 8 (IQR: 4-10) to 2 (IQR: 0-6) (p < 0.001) with 59% (429) of 727 patients reporting pain score reductions of 2 or more points. Desaturation (<90% SpO2) events were noted to be minimal (1.8%). A small number (28, 2.2%) received positive pressure ventilation without advanced airway placement. No prehospital deaths were documented.Conclusion: In this large review of pediatric prehospital ketamine use, ketamine was primarily used for analgesia, but was frequently used for other indications. Most patients were observed to improve after ketamine use, with most injured patients reporting decreases in pain scores. We observed few significant adverse events related to ketamine use in this population.

A Comparison of Prehospital Pediatric Analgesic Use of Ketamine and Opioids.

OBJECTIVE/INTRODUCTION: Ketamine is an opioid-alternative used for analgesia in the prehospital setting. There are knowledge gaps regarding its use during emergency medical services (EMS) encounters for pediatric patients. Our objective was to compare pain reduction, adverse events, and prehospital deaths between ketamine and opioids when used for analgesia administered by any route among pediatric patients. METHODS: This was a retrospective review of 9-1-1 EMS records of injured pediatric patients (≤17 years of age) who received ketamine or opioids for analgesia using the ESO Data Collaborative (calendar years 2019-2020). We excluded interfacility transfers, patients receiving both medications, those with EMS clinician impressions indicating behavioral disorders, and those who received medication to facilitate advanced airway placement. EMS narrative review was performed to confirm ketamine use was for analgesia and to identify any unplanned airway placements. We assessed pain score reduction (0-10 ordinal scale) and clinician-documented patient response (improved, unchanged, worsened, unknown). Adverse events were defined as change in vital signs (GCS, SBP, RR, SpO2), bag valve mask ventilation alone, or death. Descriptive statistics were calculated to compare outcomes between groups. RESULTS: Overall, 9,223 patients were included, 190 (2.1%) received ketamine and 9,033 (97.9%) received opioids. Mean age in years was 12.8 [SD 4.0] for ketamine and 12.7 [SD 4.0] for opioids. Patients in both groups experienced pain reduction, and more patients receiving ketamine had EMS clinician reported improvement (93.2% vs. 87.9%, p = 0.03). Ketamine was associated with a greater average reduction in pain score than opioids (mean difference: -4.4 [SD 3.5], and -3.1 [SD 2.8], p < 0.001). Adverse events were rare with few patients receiving ventilatory support following the use of ketamine or opioids, (0, [SD 0.0%] vs. 6 [SD 0.1%], p = 1). There were no unplanned airway placements or prehospital deaths identified. CONCLUSION: We identified similar high rates of pain reduction and rare adverse events among pediatric patients who received ketamine or opioids. A greater pain reduction was noted among patients administered ketamine. Intubation as a result of medication administration did not occur and need for ventilatory assistance was rare.

Prehospital Use of Ketamine versus Benzodiazepines for Sedation among Pediatric Patients with Behavioral Emergencies.

INTRODUCTION: Ketamine is an emerging alternative sedation agent for prehospital management of agitation, yet research is limited regarding its use for children. Our objective was to compare the effectiveness and safety of ketamine and benzodiazepines when used for emergent prehospital sedation of pediatric patients with behavioral emergencies. METHODS: We performed a retrospective review of 9-1-1 EMS records from the 2019-2020 ESO Data Collaborative research datasets. We included patients ≤18 years of age who received ketamine or benzodiazepines for EMS primary and secondary impressions indicating behavioral conditions. We excluded patients with first Glasgow Coma Scale (GCS) scores ≤8, those receiving ketamine or benzodiazepines prior to EMS arrival, those receiving both ketamine and benzodiazepines, and interfacility transfers. Effectiveness outcomes included general clinician assessment of improvement, decrease in GCS, and administration of a subsequent sedative. Safety outcomes included mortality; advanced airway placement; ventilatory assistance without advanced airway placement; or marked sedation (GCS ≤8). Chi-square and t-tests were used to compare the ketamine and benzodiazepines groups. RESULTS: Of 57,970 pediatric patients with behavioral complaints and GCS scores >8, 1,539 received ketamine (13.3%, n = 205) or a benzodiazepine (86.7%, n = 1,334). Most patients were ≥12 years old (89.2%, n = 1,372), predominantly Caucasian (48.3%, n = 744), and were equally distributed by sex (49.7% male, n = 765). First treatment with ketamine was associated with a greater likelihood of improvement (88.8% vs 70.5%, p < 0.001) and a greater average GCS reduction compared to treatment with benzodiazepines (-2.5 [SD:4.0] vs -0.3 [SD:1.7], p < 0.001). Fewer patients who received ketamine received subsequent medication compared to those who received benzodiazepines (12.2% vs 27.0%, p < 0.001). Marked sedation was more frequent with ketamine than benzodiazepines (28.8% vs 2.9%, p < 0.001). Provision of ventilatory support (1.5% vs 0.5%, p = 0.14) and advanced airway placement (1.0% vs 0.2%, p = 0.09) were similar between ketamine and benzodiazepine groups. No prehospital deaths were reported. CONCLUSION: In this pediatric cohort, prehospital sedation with ketamine was associated with greater patient improvement, less subsequent sedative administration, and greater sedation compared to benzodiazepines. Though we identified low rates of adverse events in both groups, ketamine was associated with more instances of marked sedation, which bears further study.

Feasibility Study of Caregiver-Provided Life Review: Implementation, Adaptation, and Effects on Care Recipients' Depressive Symptoms.

OBJECTIVES: This study aimed to examine the feasibility of unpaid, family/friend caregivers conducting life reviews with people with dementia in long-term care and community settings and reported on how we adapted the intervention modality under the COVID-19 pandemic. METHODS: Twenty-one caregiver-care recipient dyads completed 6 weekly life review sessions. The intervention format was modified to accommodate COVID-19 restrictions. Primary and secondary outcome measures were analyzed based on repeated measures at baseline and post-intervention. RESULTS: Due to the changing nature of the pandemic, we iterated the caregiver training intervention four times to accommodate caregivers' needs while having faced multiple recruitment challenges with care facility residents. Care recipients' depression appeared to have improved (p = .001). CONCLUSIONS: Although the COVID-19 pandemic created unique recruitment challenges, all the care recipients seemed to enjoy the life review activities supported by the positive outcomes in gaining socialization opportunities. It may be beneficial to offer a more self-paced intervention modality to ease the burden on caregivers. CLINICAL IMPLICATIONS: It appears that unpaid family/friend caregivers can provide life reviews to their loved ones with dementia. Training the caregivers on how to provide life reviews can be an easy, low-risk activity that might ameliorate depressive symptoms in the care recipients.

Health of Vietnamese Older Adults and Caregiver's Psychological Status in the United States: Result from the Vietnamese Aging and Care Survey.

Objective: We examined the association between care recipient's physical, mental, and cognitive health conditions and caregivers' psychological distress in Vietnamese older care recipients and their caregivers.Methods: The Vietnamese Aging and Care Survey was developed for care recipients, and adult-child and spousal caregivers, and inquired about their sociodemographics and health-related variables.Results: Data were collected on 58 caregiver-care recipient dyads. Adult-child and spousal caregivers were on average 43 and 70 years-old respectively. The vast majority were female (76%) and born in Vietnam (97%). Adult-child caregivers reported more caregiver burden than spousal caregivers. Care recipients were on average 75 years-old. Care recipients of adult-child caregivers reported more depressive symptoms than care recipients of spousal caregivers and were more likely to have mild dementia. Care recipients' health had no effect on caregiver depressive symptoms but their educational attainment was associated with caregiver burden and depressive symptoms.Conclusions: This study showed care recipients and caregivers' years of education were positively associated with caregivers' psychological distress. Vietnamese families lived in ethnic enclaves and shared caregiving responsibilities within the family. However, using available outside resources may alleviate psychological distress of not only caregivers but also families as a whole.Clinical Implications: Healthcare professionals should encourage educated caregivers and educated care recipients to use outside resources to ease caregiving duties.

Depressive symptoms in child caregivers of very old Mexican Americans.

OBJECTIVE: To study the effects of disability, cognitive impairment, and neuropsychiatric disturbance among older Mexican Americans on depressive symptoms in their children caregivers. METHODS: This study utilizes data from Wave 7 (2010-2011) of the Hispanic Established Populations for the Epidemiologic Study of the Elderly (HEPESE). The final sample included 200 adult children caregivers that provided direct personal care with activities of daily living (ADL) (e.g. bathing, toileting, dressing, etc.) to their older parents (average age = 87). We analyzed the influence of ADL disability, cognition (MMSE), and neuropsychiatric symptoms (NPI) of the care recipient on depressive symptoms of the adult child caregiver. A cross-sectional multivariable linear regression analysis was conducted to examine the effect of neuropsychiatric disturbance on caregiver depressive symptoms. RESULTS: Presence of care recipient NPI symptoms was associated with higher depressive symptoms for caregivers. Additional characteristics associated with caregiver depressive symptoms were not being married, and higher perceived social stress. ADL disability of the care recipient, cognitive functioning of the care recipient, or caregiver health status alone did not have a significant effect on depressive symptoms of the caregiver. CONCLUSIONS: In a Mexican American familistic culture, disability and cognitive impairment might be better tolerated by families but neuropsychiatric behavioral symptoms related to dementia may take an increased toll on family member caregivers. The need to provide respite services, mental health resources and community services for caregivers of care recipients with neuropsychiatric symptoms is of paramount importance to alleviate depressive symptoms and burden among caregivers.

Left Ventricular Ejection Fraction Assessment by Emergency Physician-Performed Bedside Echocardiography: A Prospective Comparative Evaluation of Multiple Modalities.

BACKGROUND: Although there is some support for visual estimation (VE) as an accurate method to estimate left ventricular ejection fraction (LVEF), it is also scrutinized for its subjectivity. Therefore, more objective assessments, such as fractional shortening (FS) or e-point septal separation (EPSS), may be useful in estimating LVEF among patients in the emergency department (ED). OBJECTIVE: Our aim was to compare the real-world accuracy of VE, FS, and EPSS using a sample of point-of-care cardiac ultrasound transthoracic echocardiography (POC-TTE) images acquired by emergency physicians (EPs) with the gold standard of Simpson's method of discs, as measured by comprehensive cardiology-performed echocardiography. METHODS: We conducted a single-site prospective observational study comparing VE, FS, and EPSS to assess LVEF. Adult patients in the ED receiving both POC-TTE and comprehensive cardiology TTE were included. EPs acquired POC-TTE images and videos that were then interpreted by 2 blinded EPs who were fellowship-trained in emergency ultrasound. EPs estimated LVEF using VE, FS, and EPSS. The primary outcome was accuracy. RESULTS: Between April and May 2018, 125 patients were enrolled and 113 were included in the final analysis. EP1 and EP2 had a κ of 0.94 (95% confidence interval [CI] 0.87-1.00) and 0.97 (95% CI 0.91-1.00), respectively, for VE compared with gold standard, a κ of 0.40 (95% CI 0.23-0.57) and 0.38 (95% CI 0.18-0.57), respectively, for EPSS compared with gold standard, and a κ of 0.70 (95% CI 0.54-0.85) and 0.66 (95% CI 0.50-0.81), respectively, for FS compared with gold standard. Sensitivity of severe dysfunction was moderate to high in VE (EP1 85% and EP2 93%), poor to moderate in FS (EP1 73% and EP2 50%), and poor in EPSS (EP1 11% and EP2 18%). CONCLUSIONS: Using a real-world sample of POC-TTE images, the quantitative measurements of EPSS and FS demonstrated poor accuracy in estimating LVEF, even among experienced sonographers. These methods should not be used to determine cardiac function in the ED. VE by experienced physicians demonstrated reliable accuracy for estimating LVEF compared with the gold standard of cardiology-performed TTE.

Ultralong Versus Standard Long Peripheral Intravenous Catheters: A Randomized Controlled Trial of Ultrasonographically Guided Catheter Survival.

STUDY OBJECTIVE: Ultrasonographically guided intravenous peripheral catheters have dismal dwell time, with most intravenous lines failing before completion of therapy. Catheter length in the vein is directly related to catheter longevity. We investigate the survival of an ultralong ultrasonographically guided intravenous peripheral catheter compared with a standard long one. METHODS: We conducted a single-site, nonblinded, randomized trial of catheter survival. Adult patients presenting to the emergency department with difficult vascular access were recruited and randomized to receive either standard long, 4.78-cm, 20-gauge ultrasonographically guided intravenous peripheral catheters or ultralong, 6.35-cm, 20-gauge ultrasonographically guided intravenous peripheral catheters. The primary outcome was duration of catheter survival. The secondary outcome was the optimal length of the catheter in the vein to maximize survival. Additional intravenous-related endpoints included first-stick success, time to insertion, number of attempts, thrombosis, and infection. RESULTS: Between October 2018 and March 2019, 257 patients were randomized, with 126 in the standard long ultrasonographically guided intravenous peripheral catheter group and 131 in the ultralong group. Kaplan-Meier estimate of catheter median survival time in the ultralong group was 136 hours (95% confidence interval [CI] 116 to 311 hours) compared with 92 hours (95% CI 71 to 120 hours) in the standard long group, for a difference of 44 hours (95% CI 2 to 218 hours). The optimal catheter length in the vein was 2.75 cm, and intravenous lines with greater than 2.75 cm inserted had a median survival of 129 hours (95% CI 102 to 202 hours) compared with 75 hours (95% CI 52 to 116 hours) for intravenous lines with less than or equal to 2.75 cm, for a difference of 54 hours (95% CI 10 to 134 hours). Insertion characteristics were similar between the groups: 74.1% versus 79.4% first-stick success (95% CI for the difference -2% to 5%), 1.4 versus 1.3 for number of attempts (95% CI for the difference -0.1 to 0.3), and 6.9 versus 5.9 minutes to completion (95% CI for the difference -1.3 to 3.4) with ultralong versus standard long, respectively. There were no cases of infection or thrombosis. CONCLUSION: This study demonstrated increased catheter survival when the ultralong compared with the standard long ultrasonographically guided intravenous peripheral catheter was used, whereas insertion characteristics and safety appeared similar.

Soy isoflavones interact with calcium and contribute to blood pressure homeostasis in women: a randomized, double-blind, placebo controlled trial.

BACKGROUND: Estrogens and calcium regulate vascular health but caused adverse cardiovascular events in randomized trials. OBJECTIVES: Whether phytoestrogenic soy isoflavones modulate the physiological effects of calcium on blood pressure was explored. DESIGN: A double-blind, randomized study assigned 99 premenopausal women to 136.6 mg isoflavones (as aglycone equivalents) and 98 to placebo for 5 days per week for up to 2 years. Blood pressure, serum calcium and urinary excretion of daidzein (DE) and genistein (GE) were measured repeatedly before and during treatment. RESULTS: Isoflavones did not affect blood pressure per intake dose assignment (i.e. intention-to-treat, n = 197), but significantly affected blood pressure per measured urinary excretion of isoflavones (i.e. per protocol analysis, n = 166). Isoflavones inversely moderated calcium effects on systolic blood pressure (SBP) (interaction term ß-estimates: - 3.1 for DE, - 12.86 for GE, all P < 0.05), and decreased diastolic blood pressure (DBP) (ß-estimates: - 0.84 for DE, - 2.82 for GE, all P < 0.05) after controlling for calcium. The net intervention effects between the maximum and no isoflavone excretion were - 17.7 and + 13.8 mmHg changes of SBP, respectively, at serum calcium of 10.61 and 8.0 mg/dL, and about 2.6 mmHg decrease of DBP. CONCLUSIONS: Moderation by isoflavones of the physiological effect of calcium tends to normalize SBP, and this effect is most significant when calcium concentrations are at the upper and lower limits of the physiological norm. Isoflavones decrease DBP independent of calcium levels. Further studies are needed to assess the impact of this novel micronutrient effect on blood pressure homeostasis and cardiovascular health.

Can Family Caregivers Provide Life Review to Reduce Depression in Older Adults With Dementia?

Life review (LR) therapy has received considerable support as an effective treatment for depression among older adults. Researchers believe that providing LR does not require extensive training and can be done by family members who are not psychiatric professionals. If so, then training family caregivers to provide LR is a potential strategy for alleviating the shortage of resources for treating depression among the growing population of older adults experiencing depression. A pilot study that explored the feasibility of that strategy had mixed results. Seventeen (89%) of 19 caregiver-care recipient dyads completed the current study, and caregivers provided the LR with self-reported fidelity. However, there was lack of statistically significant improvement in this convenience sample. Implications are provided for future assessments of this strategy with a larger study of caregiver and care recipient dyads. [Journal of Gerontological Nursing, 46(2), 41-48.].

Vietnamese Adult-Child and Spousal Caregivers of Older Adults in Houston, Texas: Results from the Vietnamese Aging and Care Survey (VACS).

Vietnamese are the largest Asian ethnic group in Houston, Texas; however, research on this population is scarce. To address this dearth of knowledge, we developed the Vietnamese Aging and Care Survey. The objective of the study was to explore the sociodemographic and health characteristics of Vietnamese adults aged 65 years and older (n = 132) and their family caregivers (n = 64). Adult-child caregivers (n = 41) were aged between 21 and 65 years old. The majority were married, working, female, and in good to excellent health. Spousal caregivers (n = 23) were between 57 and 82 years old, retired, female, and in fair to good health. Adult children received more caregiving-related help from others compared to spousal caregivers; however, they felt more caregiver burden, had more perceived stress, and were in challenging relationships with care recipients. Differences in life stages of adult-child versus spousal caregivers may contribute to these results. Implications are discussed.

Falls in Mexican older adults aged 60 years and older.

BACKGROUND: Falls are a major cause of disability, morbidity, institutionalization, and mortality in older adults. OBJECTIVES: The purpose of the study was to examine the risk factors for falls among Mexican older adults aged 60 years and older. METHODS: This study included 6247 participants and their spouse or partner aged 60 years and older from the Mexican Health and Aging Study, an ongoing longitudinal study (2001-2012) conducted in Mexico. Measures included socio-demographics, falls, physical activity, comorbid conditions, pain, vertigo, vision and hearing impairments, urinary incontinence, lower extremity functional limitation, activities of daily living (ADLs), cognitive function, and depressive symptoms. RESULTS: Mean age was 69.6 years (standard error = 0.18) and 51.8% were female. Forty percent reported one or more falls at baseline. Older age, being female, obesity, arthritis, fractures, stroke, suffering pain, vertigo, lower extremity functional limitations, physical activity, depressive symptoms, urinary incontinence, and ADL disability were significant factors associated with one or more falls over time. DISCUSSION: Early detection and treatment of the risk factors for falls in this population will help improve the quality of life and reduce medical complications and health care costs.

Riboflavin as an independent and accurate biomarker for adherence in a randomized double-blind and placebo-controlled clinical trial.

BACKGROUND: Medication adherence is critical for success of clinical trials. OBJECTIVE: To assess oral riboflavin is an adherence marker. METHODS: Riboflavin was incorporated into active treatment and placebo pills for a clinical trial lasting for 2 years. RESULTS: The accuracy (area under the receiver operating curve) of urinary riboflavin was 0.91 as a binary classifier of adherence, and was similar or better than for two active study ingredients daidzein (0.92) and genistein (0.87) (all p < 0.0001). Decreased adherence over time was similar in the two study groups. CONCLUSION: Riboflavin is an accurate and useful biomarker for study pill ingestion.

A longitudinal study of cognitive trajectories in Mexican Americans age 75 and older.

OBJECTIVE: To identify distinct trajectories for global cognition, memory, and non-memory domains among Mexican American adults 75 years of age and older. METHODS: The final sample included 1336 participants of the Hispanic Established Population for the Epidemiologic Study of the Elderly observed during four Waves from 2004-2005 to 2012-2013. Latent class growth curve models were used to identify distinct trajectories for global cognition, memory, and non-memory. RESULTS: Three trajectory classes were identified for global cognition, memory, and non-memory domains. Nearly 31% of the final sample maintained high global cognition (persistent high), 52.6% experienced slight decline (decline but high), and 15% experienced severe decline in global cognition (decline to low). Over 95% of participants classified in the decline to low trajectory for global cognition were also classified as decline to low for memory and non-memory. This high level of consistency for memory and non-memory domains was observed for the decline but high (97.0%) and persistent high (93.7%) trajectory classes. CONCLUSIONS: These results indicate that the majority of Mexican American older adults will experience varying degrees of cognitive decline. However, a substantial proportion of older Mexican Americans are able to maintain high cognitive functioning into advanced age despite the high prevalence of risk factors for cognitive decline in this population.

Impact of Laws Regulating Pain Clinics on Opioid Prescribing and Opioid-Related Toxicity Among Texas Medicare Part D Beneficiaries.

BACKGROUND: Pain management clinics are major sources of prescription opioids. Texas government passed several laws regulating pain clinics between 2009 and 2011 to reduce opioid-related toxicity. Understanding the impact of these laws can inform policy geared toward making the laws more effective in curbing the growing epidemic of opioid overdose, especially among the elderly population. OBJECTIVES: To examine the longitudinal association of laws regulating pain clinics on opioid-prescribing and opioid-related toxicity among Texas Medicare recipients. METHODS: The 2007 to 2012 claims data for Texas Medicare Part D recipients were used to assess temporal trends in the percentage of patients filling any schedule II or schedule III opioid prescription, hospitalization for opioid toxicity, and their relationships to the 2009 to 2011 Texas laws regulating pain clinics. We excluded those with a cancer diagnosis. Join-point trend analysis with Bayesian Information Criterion selection methods were used to evaluate the change in monthly percentages of patients filling opioid prescriptions and hospitalization over time. RESULTS: There was a short-lived decline in the monthly percentages of patients who filled a schedule II or schedule III opioid prescription after the 2009 laws regulating pain clinics. The decline lasted about 3 months. Subsequent new laws had no effect on the percentages of patients who filled any opioid prescription or were hospitalized for potential opioid toxicity. Hospitalizations for opioid toxicity were highest in the winter and lowest in the summer. CONCLUSIONS: Changes in the percentages of opioid-prescribing or opioid-related hospitalizations over time were not associated with laws regulating pain clinics.

Alcohol Use after Liver Transplantation is Independent of Liver Disease Etiology.

AIM: To assess alcohol use after liver transplantation (LT) and compare liver transplant recipients for alcoholic liver disease (ALD) with recipients for non-ALD causes. METHODS: National Institute of Diabetes and Digestive and Kidney Diseases liver transplant database stratified to ALD and non-ALD causes. RESULTS: Among 488 LT recipients reporting pre-transplant alcohol use (147 ALD), proportion of LT recipients reporting alcohol use was similar comparing ALD and non-ALD transplants (25.4% vs. 27.2%; P = 0.56). Among ALD transplants, of 31 with alcohol use, 23 (74%) relapsed at ≥2 year, 25 (80%) reported intermittent drinking and 4 (13%) reported heavy drinking. Among Non-ALD recipients, alcohol use was equally distributed to within 2, 2-5 and after 5 years of LT with 82% reporting intermittent drinking and 9% heavy drinking. Patients with pre-transplant drinking of >20 years and abstinence duration of <2 years were over 2.5-fold likely to report post-transplant alcohol use compared to drinking of >20 years and abstinence of >2 years, 2.56 [95% CI: 1.41-4.67]. Etiology (ALD vs. non-ALD) did not predict post-transplant alcohol use. Of 139 ALD patients with follow-up biopsy data, 13 (7 with post-transplant alcohol use) had steatohepatitis. Histology on 319 non-ALD recipients showed recurrent disease in 91, none due to alcohol. Overall survival was similar between drinkers and abstainers (71% vs. 66%; P = 0.35). Recurrent ALD was cause of death in one ALD and none of non-ALD patients. CONCLUSION: Alcohol use after LT is independent of LT indication. Patients with non-ALD etiology should be carefully screened for alcohol use prior to LT to identify those at risk for post-LT alcohol use.

Potentially Preventable Hospitalizations in Medicare Patients With Diabetes: A Comparison of Primary Care Provided by Nurse Practitioners Versus Physicians.

BACKGROUND: Few comparisons exist of the quality of primary care provided by nurse practitioners (NPs) versus physicians. METHODS: Patients with a diagnosis of diabetes in 2007-2010 (n=345,819) who received all primary care from NPs or from generalist physicians in a given year were selected from a national sample of Medicare beneficiaries. We compared the rate of potentially preventable hospitalizations among patients who received primary care from NPs versus generalist physicians. Various statistical methods-including multivariable analysis, inverse probability weighting of propensity score, nonpooling propensity score adjustment and matching, and instrumental variable (IV) analysis-were used to control for differences in patient characteristics between the 2 groups. RESULTS: Patients who received all of their primary care from NPs or from physicians differed by age, sex, race/ethnicity, socioeconomic status, residential area, and number of provider visits in the previous year. Nonpooling propensity score matching substantially reduced the differences, but neither IV approach satisfactorily reduced the differences. In multivariable analyses, receipt of primary care from an NP was associated with a decreased risk of hospitalization for potentially preventable conditions (OR: 0.90; 95% CI, 0.87-0.93). Similar results were found using conditional logistic regression models with propensity methods. We found smaller reductions in our analyses of "other hospitalizations" (OR: 0.96; 95% CI, 0.95-0.98). Both IV analyses showed associations between NP care and lower potentially preventable hospitalizations, but only 1 result was statistically significant. CONCLUSIONS: Using potentially preventable hospitalizations as a quality indicator, primary care provided by NPs was at least comparable with that provided by generalist physicians.

Association of Epigenetic Age and Everyday Discrimination With Longitudinal Trajectories of Chronic Health Conditions in Older Adults.

We investigated the strength of the association between baseline epigenetic age, everyday discrimination, and trajectories of chronic health conditions (CHCs) across 3 study waves, among adults 50 years of age and older. We used 2016-2020 data from the Health and Retirement Study (HRS). Data for the PhenoAge and DNAm GrimAge second-generation epigenetic clocks were from the 2016 HRS Venous Blood Study. CHC trajectories were constructed using latent class growth curve models. Multinomial logistic regression models assessed the strength of the association between accelerated epigenetic age, everyday discrimination, and the newly constructed CHC trajectories for participants with complete data (n = 2 893). In the fully adjusted model, accelerated PhenoAge (relative risk ratios [RRR] = 2.53, 95% confidence interval [95% CI] = 1.81, 3.55) and DNAm GrimAge (RRR = 2.79, 95% CI = 1.95, 4.00) were associated with classification into the high CHC trajectory class. Racial disparities were evident, with increased risk of classification into the high trajectory class for Black (PhenoAge: RRR = 1.69, 95% CI = 1.07, 2.68) and reduced risk for Hispanic (PhenoAge: RRR = 0.32, 95% CI = 0.16, 0.64; DNAm GrimAge: RRR = 0.34, 95% CI = 0.17, 0.68), relative to White participants. Everyday discrimination was associated with classification into the medium-high (RRR = 1.28, 95% CI = 1.00, 1.64) and high (RRR = 1.52, 95% CI = 1.07, 2.16) trajectory classes in models assessing DNAm GrimAge. More research is needed to better understand the longitudinal health outcomes of accelerated aging and adverse social exposures. Such research may provide insights into vulnerable adults who may need varied welfare supports earlier than the mandated chronological age for access to federal and state resources.

Early Emergency Medicine Milestone Assessment for Predicting First-Year Resident Performance.

Introduction: The Accreditation Council for Graduate Medical Education (ACGME) requires emergency medicine (EM) residency training programs to monitor residents' progress using standardized milestones. The first assessment of PGY 1 resident milestones occurs midway through the first year and could miss initial deficiencies. Early assessment of PGY 1 EM resident milestones has potential to identify at-risk residents prior to standard midyear evaluations. We developed an orientation syllabus for PGY 1 residents followed by a milestone assessment. Assessment scores helped predict future milestone scores and American Board of Emergency Medicine (ABEM) In-Training Examination (ITE) scores for PGY 1 residents. Methods: From 2013 to 2020, we developed and implemented Milestone Evaluation Day (MED), a simulation-based day and written exam assessing PGY 1 EM residents during their first month on the 23 ACGME 1.0 milestones. MED stations included a history and physical with verbal presentation, patient simulation, vascular access, wound management, and airway management. MED, Clinical Competency Committee-generated (CCC-generated) milestone, and ABEM ITE scores were averaged and compared utilizing Pearson's correlation coefficient. Results: Of 112 PGY 1 EM residents, 110 (98%) were analyzed over an 8-year period. We observed a moderate positive correlation of MED and CCC-generated milestone scores (r = .34, p < .001). There was a nonstatistically significant weak positive correlation of MED and ABEM ITE scores (r = .13, p = .17). Discussion: An early assessment of EM milestones in the PGY 1 year can assist in the prediction of CCC-generated milestone scores for PGY 1 residents.
