Importance: Recent evolutions in clinical care and remote monitoring suggest that some acute illnesses no longer require intravenous therapy and inpatient hospitalization., Objective: To describe outcomes of patients receiving care in a new, outpatient, virtual, home-based acute care model called Safer@Home., Design, Setting, and Participants: This retrospective cohort analysis, conducted from September 1, 2022, through August 31, 2023, included 2466 patients treated at a safety net hospital in Los Angeles County for 10 core illnesses and 24 other acute illnesses for which patients are commonly hospitalized., Exposure: Outpatient, home-based, acute care with virtual monitoring and clinic visits in lieu of inpatient or in-home care., Main Outcomes and Measures: The primary measure was hospital length of stay. Secondary measures included all-cause mortality, 30-day readmission, return urgent care visit rates, and return emergency department (ED) visit rates., Results: Safer@Home provided care to 876 patients (mean [SD] age, 54.0 [14.5] years; 541 men [61.8%]) during the study period, compared with a cohort of 1590 patients (mean [SD] age, 52.3 [19.6] years; 901 men [56.7%]) with matching diagnoses who received standard, hospital-based care. Safer@Home patients had significantly shorter mean (SD) lengths of inpatient stay than the comparison cohort (1.3 [2.0] vs 5.3 [10.4] days; P < .001), totaling 3505 bed-days avoided (mean [SD], 4.0 [10.6] bed-days saved per patient), with no significant difference in all-cause mortality at last follow-up (2.6% [23 of 876] vs 4.0% [64 of 1590]; P = .07). Safer@Home patients and control patients also had no significant difference in the proportion experiencing 30-day hospital readmission (19.9% [174 of 876] vs 16.7% [266 of 1590]; P = .06). As intended, more Safer@Home than control patients had at least one 30-day return urgent care visit (37.3% [327 of 876] vs 5.2% [82 of 1590]; P < .001). In contrast, the Safer@Home and control cohorts did not significantly differ in experiencing at least one 30-day return ED visit (15.2% [133 of 876] vs 12.5% [199 of 1590]; P = .06). Safer@Home patients had significantly fewer mean (SD) total 30-day return ED visits per patient than control patients (0.19 [0.50] vs 0.21 [0.85]; P < .001)., Conclusions and Relevance: In this cohort study, patients receiving acute, virtual, home care with remote monitoring and as-needed return urgent care visits had markedly shorter hospital stays than patients receiving standard inpatient hospital care, with no significant increase in mortality, ED revisits, or return hospitalizations. This new care model is promising for systems that cannot staff Medicare-compliant hospital-at-home visits.

Background: We sought to compare the outcomes of patients treated with intravenous (IV)-only vs oral transitional antimicrobial therapy for infective endocarditis (IE) after implementing a new expected practice within the Los Angeles County Department of Health Services (LAC DHS)., Methods: We conducted a multicentered, retrospective cohort study of adults with definite or possible IE treated with IV-only vs oral therapy at the 3 acute care public hospitals in the LAC DHS system between December 2018 and June 2022. The primary outcome was clinical success at 90 days, defined as being alive and without recurrence of bacteremia or treatment-emergent infectious complications., Results: We identified 257 patients with IE treated with IV-only (n = 211) or oral transitional (n = 46) therapy who met study inclusion criteria. Study arms were similar for many demographics; however, the IV cohort was older, had more aortic valve involvement, were hemodialysis patients, and had central venous catheters present. In contrast, the oral cohort had a higher percentage of IE caused by methicillin-resistant Staphylococcus aureus. There was no significant difference between the groups in clinical success at 90 days or last follow-up. There was no difference in recurrence of bacteremia or readmission rates. However, patients treated with oral therapy had significantly fewer adverse events. Multivariable regression adjustments did not find significant associations between any selected variables and clinical success across treatment groups., Conclusions: These results demonstrate similar outcomes of real-world use of oral vs IV-only therapy for IE, in accord with prior randomized, controlled trials and meta-analyses., Competing Interests: Potential conflicts of interests.

Purpose: A primary cause of hospital readmission is medication-related problems (MRPs). Polypharmacy patients taking multiple medications concurrently experience an increased likelihood of MRPs and high occurrence of readmissions to the hospital within 30 days. This study assessed the ability of a pharmacist-led transition of care program to decrease readmissions in polypharmacy patients by evaluating and rectifying MRPs., Methods: Over 16 months, patients admitted onto the medicine ward service with ≥10 home medications ( n = 536) received medication management interventions from a clinical pharmacist including admission interview, medication reconciliation and consultation, and postdischarge phone follow-up. Admitted patients taking fewer than 10 home medications during the same time served as the control group and received routine standard of care ( n = 2317)., Results: The polypharmacy group who received the pharmacist-led intervention had a statistically significantly lower 30-day readmission rate (8.8%) compared with patients in the control group (12.4%; X 2 = 5.63, p = .01). Patients receiving pharmacist intervention were 33% less likely to be readmitted within 30 days of discharge compared with the control group (odds ratio = 0.67, 95% CI = 0.49-0.94). All patients had at least one medication-related discrepancy., Conclusion: This pharmacy-led transition of care program can effectively reduce readmission rates through resolution of medication-related problems., Competing Interests: The authors have no conflicts of interest to disclose and received no funding for this study., (Copyright © 2023 National Association for Healthcare Quality.)

We conducted a quality improvement project at our large, public, tertiary-care, academic hospital to reduce the standardized infection ratio (SIR) of hospital-acquired catheter-associated urinary tract infections (CAUTIs). Our diagnostic stewardship program, based on education and audit and feedback, significantly reduced inpatient urine culture orders and CAUTI SIR., (© The Author(s) 2020.

Importance: To optimize patient outcomes and preserve critical acute care access during the COVID-19 pandemic, the Los Angeles County Department of Health Services developed the SAFE @ HOME O2 Expected Practice (expected practice), enabling ambulatory oxygen management for COVID-19., Objective: To assess outcomes of patients with COVID-19 pneumonia discharged via the expected practice approach to home or quarantine housing with supplemental home oxygen., Design, Setting, and Participants: This retrospective cohort study included 621 adult patients with COVID-19 pneumonia who were discharged from 2 large urban public hospitals caring primarily for patients receiving Medicaid from March 20 to August 19, 2020. Patients were included in the analysis cohort if they received emergency or inpatient care for COVID-19 and were discharged with home oxygen., Interventions: Patients receiving at least 3 L per minute of oxygen, stable without other indication for inpatient care, were discharged from either emergency or inpatient encounters with home oxygen equipment, educational resources, and nursing telephone follow-up within 12 to 18 hours of discharge. Nurses provided continued telephone follow up as indicated, always with physician back-up., Main Outcomes and Measures: All-cause mortality and all-cause 30-day return admission., Results: A total of 621 patients with COVID-19 pneumonia (404 male [65.1%] and 217 female [34.9%]) were discharged with home oxygen. Median age of these patients was 51 years (interquartile range, 45-61 years), with 149 (24.0%) discharged from the emergency department and 472 (76%) discharged from inpatient encounters. The all-cause mortality rate was 1.3% (95% CI, 0.6%-2.5%) and the 30-day return hospital admission rate was 8.5% (95% CI, 6.2%-10.7%) with a median follow-up time of 26 days (interquartile range, 15-55 days). No deaths occurred in the ambulatory setting., Conclusions and Relevance: In this cohort study, patients with COVID-19 pneumonia discharged on home oxygen had low rates of mortality and return admission within 30 days of discharge. Ambulatory management of COVID-19 with home oxygen has an acceptable safety profile, and the expected practice approach may help optimize outcomes, by ensuring right care in the right place at the right time and preserving access to acute care during the COVID-19 pandemic.

Background: Tourniquets are a critical tool in the immediate response to life-threatening extremity hemorrhage; however, the optimal tourniquet type and effectiveness of noncommercial devices remain unclear. Our aim was to evaluate the efficacy of five tourniquets in a perfused-cadaver model., Methods: This prospective study used a perfused-cadaver model with standardized superficial femoral artery injury bleeding at 700 mL/min. Five tourniquets were tested: combat application tourniquet; rapid application tourniquet system; Stretch, Wrap, And Tuck Tourniquet; an improvised triangle bandage windlass; and a leather belt. Forty-eight medical students underwent a practical hands-on demonstration of each tourniquet. Using a random number generator, they placed the tourniquets on the bleeding cadaver in random order. Time to hemostasis, time to secure devices, estimated blood loss, and difficulty rating were assessed. A one-way repeated measures analysis of variance was used to compare efficacy between the tourniquets in achieving the outcomes., Results: The mean ± SD participant age was 25 ± 2.6 years, and 29 (60%) were male. All but one tourniquet was able to stop bleeding, but the rapid application tourniquet system had a 4% failure rate. Time to hemostasis and estimated blood loss did not differ significantly (p > 0.05). Stretch, Wrap, And Tuck Tourniquet required the longest time to be secured (47.8 ± 17.0 seconds), whereas the belt was the fastest (15.2 ± 6.5 seconds; p < 0.001). The improvised windlass was rated easiest to learn and apply, with 22 participants (46%) assigning a score of 1., Conclusion: Four of five tourniquets evaluated, including both noncommercial devices, effectively achieved hemostasis. A standard leather belt was the fastest to place and was able to stop the bleeding. However, it required continuous pressure to maintain hemostasis. The improvised windlass was as effective as the commercial devices and was the easiest to apply. In an emergency setting where commercial devices are not available, improvised tourniquets may be an effective bridge to definitive care., (Copyright © 2020 Wolters Kluwer Health, Inc.

Background: Patient flow, from emergency department admission through to discharge, influences hospital overcrowding. We aimed to improve patient flow by increasing discharge lounge (DL) usage., Local Problem: Patients need to receive a continuum of nursing care to encourage compliance with follow-up care after discharge from the acute care setting., Methods: Baseline data revealed inefficient use of the DL. We targeted the medical-surgical unit with the lowest DL use and trialed interventions over sequential Plan-Do-Study-Act cycles., Interventions: After surveying the nursing staff, we assessed the influence of 3 interventions on DL usage: educating staff on patient eligibility, engaging a recruitment scout, and displaying a visual cue notifying staff when a patient's discharge order was written., Results: The unit's average DL use increased from 18% to 36%, while hospital overcrowding and discharge turnaround time decreased., Conclusion: The DL is an effective tool to improve patient flow and decrease hospital overcrowding.

Objective: The objective of this secondary analysis was to explore differences in baseline clinical characteristics and opioid replacement therapy treatment outcomes by type (heroin, opioid analgesic [OA], or combined [heroin and OA]) and route (injector or non-injector) of opioid use., Method: A total of 1,269 participants (32.2% female) were randomized to receive one of two study medications (methadone or buprenorphine/naloxone [BUP]). Of these, 731 participants completed the 24-week active medication phase. Treatment outcomes were opioid use during the final 30 days of treatment (among treatment completers) and treatment attrition., Results: Non-opioid substance dependence diagnoses and injecting differentiated heroin and combined users from OA users. Non-opioid substance dependence diagnoses and greater heroin use differentiated injectors from non-injectors. Further, injectors were more likely to be using at end of treatment compared with non-injectors. OA users were more likely to complete treatment compared with heroin users and combined users. Non-injectors were more likely than injectors to complete treatment. There were no interactions between type of opioid used or injection status and treatment assignment (methadone or BUP) on either opioid use or treatment attrition., Conclusions: Findings indicate that substance use severity differentiates heroin users from OA users and injectors from non-injectors. Irrespective of medication, heroin use and injecting are associated with treatment attrition and opioid misuse during treatment. These results have particular clinical interest, as there is no evidence of superiority of BUP over methadone for treating OA users versus heroin users.

Using buprenorphine as a medication to treat opioid dependence is becoming more prevalent as illicit opiate use increases. Identifying the characteristics of opiate dependent individuals best suited to benefit from buprenorphine would improve guidelines for its administration. This study evaluates baseline and treatment participation variables for predicting positive response to short-term stabilization with buprenorphine. Data include demographic, drug use, and other variables collected from participants undergoing stabilization over a 4-week period before being tapered off buprenorphine in a short-term detoxification process. Outcome variables include opioid use and retention. Logistic regression results indicate several characteristics associated with opioid use at the end of the stabilization period. These include being older, having no criminal history, and less opiate use. Criminal activity and opioid use in the last 30 days were significantly associated with shorter treatment stays. The benefits of identifying individual characteristics that may predict treatment response are discussed., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Rationale: Sensitivity to addiction-related cues, a type of attentional bias, may interfere with executive functions that are important in sustaining abstinence from drug abuse. Assessments of attentional bias in research participants who smoke cigarettes have used Smoking Stroop tasks, which are variations of emotional Stroop tasks in which the stimuli are smoking-related and neutral words., Objectives: We aimed to determine the effect of resumption of smoking by deprived cigarette smokers on attentional bias., Methods: Testing occurred twice on each of two test days. One test day began after overnight abstinence (13-16h) and the other after <1h of abstinence. The participants (n=51) smoked a cigarette between the two test sessions on each test day., Results: Smokers exhibited attentional bias for smoking-related words and had longer response times after overnight abstinence than after brief abstinence. Cigarette smoking between sessions reduced response times on both test days with no interaction by stimulus type., Conclusions: Smoking-related cues have distracting effects in smokers, and smoking reduces response latency, with no specific effect on attentional bias. The increase in response speed may contribute to a smoker's impression that abstinence hinders performance and that smoking reverses impairment., (Copyright © 2012. Published by Elsevier Ltd.)

Unlabelled: Evidence suggests that patients on opiate maintenance therapy for the treatment of addiction present with opioid-induced hyperalgesia. This study compared the experimental (cold-pressor, electrical stimulation) pain responses of 82 treatment-seeking heroin-dependent adults, randomized to methadone (METH, n = 11) or buprenorphine (BUP, n = 64) therapy, with matched drug free controls (n = 21). Heroin-dependent participants were evaluated at baseline (treatment entry), medication (METH or BUP) stabilization (4-8 weeks), and chronic administration (12-18 weeks), at trough (just prior to dosing) and peak (3 hours after dosing) plasma levels. Collection of the control group's pain responses occurred twice during a single session, 3 hours apart. Baseline comparisons indicate that heroin-dependent individuals demonstrate significantly shorter latencies to threshold and tolerance for cold-pressor pain than the control group. Across pain stimuli and time points, little change in pain responses was found over time, the exception being cold pressor pain tolerance, for which hyperalgesia significantly increased at trough METH/BUP levels in both groups as they stabilized in treatment. We conclude that heroin-dependent individuals are hyperalgesic, and that once stabilized in treatment, are not different in pain responses regardless of treatment agent. The effects of nonpharmacologic therapy and previous heroin use may explain increased hyperalgesia found with treatment., Perspective: To better understand the clinical phenomenon of opioid-induced hyperalgesia, this article describes experimental pain responses of heroin-dependent participants both prior to and over the course of maintenance therapy with methadone or buprenorphine. Hyperalgesia is present with illicit and treatment opioid use, and does not appear to appreciably improve over the course of treatment., (Copyright © 2012 American Pain Society.

Background: Clinical parameters for determining buprenorphine dose have not been adequately examined in treatment outcome research., Objectives: This study is a secondary analysis of data collected in a recently completed comparison of buprenorphine taper schedules conducted as part of the National Institute on Drug Abuse's Clinical Trials Network to assess whether participant baseline characteristics are associated with buprenorphine dose., Methods: After 3 weeks of flexible dosing, 516 participants were categorized by dose provided in the final dosing week (9.3% received a final week dose of 8 mg buprenorphine, 27.3% received 16 mg, and 63.4% received 24 mg)., Results: Findings show that final week dose groups differed in baseline demographic and drug use characteristics including education, heroin use, route of drug administration, withdrawal symptoms, and craving. These groups also differed in opioid use during the four dosing weeks, with the lowest use in the 8 mg group and highest use in the 24 mg group (p < .0001). Additional analyses address withdrawal symptoms and craving., Conclusions and Scientific Significance: Final week dose groups differed in demographic and drug use characteristics, and the group receiving the largest final week dose had the highest rate of continued opioid use. These findings may contribute to the development of clinical guidelines regarding buprenorphine dose in the treatment of opioid dependence; however, further investigations that include random assignment to dose by baseline characteristics are needed.
