To control the upward spiral of healthcare costs, hospitals seek to implement efficiency interventions whose benefits are frequently assessed by reductions in average inpatient length of stay (LOS). However, average hospital LOS is a crude metric when trying to assess the utility of an intervention focussed on a particular service or over a specific time window. It cannot isolate the time or place of the intervention from the full duration of a patient's hospital visit, which may include more than 1 hospital service or extend beyond the intervention's time window. At Montefiore Medical Center, a new analytic method was used to describe a month-long effort to improve care efficiency in a hospital teaching service. Using an extension of the Cox proportional hazard model (S-plus), we were able to analyze the contribution of only those patient-days that took place during the time window of interest on the service of interest, eliminating the contamination of the 'non intervention days.' Having built the appropriate model, we were then able to graph the behavior of the groups with and without the intervention and calculate the model's expected average LOS, controlling for the appropriate variables. By comparing this method with a conventional average LOS analysis, we demonstrate the superiority of using this 'time slice' method over the conventional analysis of LOS. [ABSTRACT FROM AUTHOR]

Introduction: Failure to document colonoscopy follow-up needs postpolypectomy can lead to delayed detection of colorectal cancer (CRC). Automating the update of a unified follow-up date in the electronic health record (EHR) may increase the number of patients with guideline-concordant CRC follow-up screening., Methods: Prospective pre-post design study of an automated rules engine-based tool using colonoscopy pathology results to automate updates to documented CRC screening due dates was performed as an operational initiative, deployed enterprise-wide May 2023. Participants were aged 45-75 years who received a colonoscopy November 2022 to November 2023. Primary outcome measure is rate of updates to screening due dates and proportion with recommended follow-up < 10 years. Multivariable log-binomial regression was performed (relative risk, 95% confidence intervals)., Results: Study population included 9,824 standard care and 19,340 intervention patients. Patients had a mean age of 58.6 ± 8.6 years and were 53.4% female, 69.6% non-Hispanic White, 13.5% non-Hispanic Black, 6.5% Asian, and 4.6% Hispanic. Postintervention, 46.7% of follow-up recommendations were updated by the rules engine. The proportion of patients with a 10-year default follow-up frequency significantly decreased (88.7%-42.8%, P < 0.001). The mean follow-up frequency decreased by 1.9 years (9.3-7.4 years, P < 0.001). Overall likelihood of an updated follow-up date significantly increased (relative risk 5.62, 95% confidence intervals: 5.30-5.95, P < 0.001)., Discussion: An automated rules engine-based tool has the potential to increase the accuracy of colonoscopy follow-up dates recorded in patient EHR. The results emphasize the opportunity for more automated and integrated solutions for updating and maintaining EHR health maintenance activities., (Copyright © 2024 The Author(s).

Background and Objectives: Healthcare is increasingly being delivered in the outpatient setting, but robust quality improvement programs and performance metrics are lacking in ambulatory care, particularly specialty-based ambulatory care., Methods: To promote quality improvement in ambulatory care, we developed an infrastructure to create specialty-specific quality measures and dashboards that could be used to display providers' performance across relevant measures to individual providers and institutional leaders., Results: The products of this program include a governance and infrastructure for specialty-specific ambulatory quality metrics as well as two distinct dashboards for data display. One dashboard is provider-facing, displaying provider's performance on specialty-specific measures as compared to institutional standards. The second dashboard is a leadership dashboard that provides overall and provider-level information on performance across measures., Conclusions: The Specialty-based Ambulatory Quality program reflects a systematic, institutionally-supported quality improvement framework that can be applied across diverse ambulatory specialties. As next steps, we plan to evaluate the program's impact on provider performance across measures and expand this program to other specialties practicing in the outpatient setting., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: Despite progress in the treatment of coronavirus disease 2019 (COVID-19), including the development of monoclonal antibodies (mAbs), more clinical data to support the use of mAbs in outpatients with COVID-19 is needed. This study is designed to determine the impact of bamlanivimab, bamlanivimab/etesevimab, or casirivimab/imdevimab on clinical outcomes within 30 days of COVID-19 diagnosis., Methods: A retrospective cohort study was conducted at a single academic medical center with 3 campuses in Manhattan, Brooklyn, and Long Island, NY. Patients 12 years of age or older who tested positive for COVID-19 or were treated with a COVID-19-specific therapy, including COVID-19 mAb therapies, at the study site between November 24, 2020, and May 15, 2021, were included. The primary outcomes included rates of emergency department (ED) visit, inpatient admission, intensive care unit (ICU) admission, or death within 30 days from the date of COVID-19 diagnosis., Results: A total of 1,344 mAb-treated patients were propensity matched to 1,344 patients with COVID-19 patients who were not treated with mAb therapy. Within 30 days of diagnosis, among the patients who received mAb therapy, 101 (7.5%) presented to the ED and 79 (5.9%) were admitted. Among the patients who did not receive mAb therapy, 165 (12.3%) presented to the ED and 156 (11.6%) were admitted (relative risk [RR], 0.61 [95% CI, 0.50-0.75] and 0.51 [95% CI, 0.40-0.64], respectively). Four mAb patients (0.3%) and 2.64 control patients (0.2%) were admitted to the ICU (RR, 01.51; 95% CI, 0.45-5.09). Six mAb-treated patients (0.4%) and 3.37 controls (0.3%) died and/or were admitted to hospice (RR, 1.61; 95% CI, 0.54-4.83). mAb therapy in ambulatory patients with COVID-19 decreases the risk of ED presentation and hospital admission within 30 days of diagnosis., (© American Society of Health-System Pharmacists 2022.

Coronavirus disease 2019 (COVID-19) reverse-transcription polymerase chain reaction employee testing was implemented across New York University Langone Health. Over 8 weeks, 14 764 employees were tested; 33% of symptomatic employees, 8% of asymptomatic employees reporting COVID-19 exposure, and 3% of employees returning to work were positive. Positivity rates declined over time, possibly reflecting the importance of community transmission and efficacy of personal protective equipment., (© The Author(s) 2020.

Medicare's Bundle Payment for Care Improvement (BPCI) Model 2 groups reimbursement for valve surgery into 90-day episodes of care, which include operative costs, inpatient stay, physician fees, postacute care, and readmissions up to 90 days postprocedure. We analyzed our BPCI patients' 90-day outcomes to understand the late financial risks and implications of the bundle payment system for valve patients. All BPCI valve patients from October 2013 (start of risk-sharing phase) to December 2015 were included. Readmissions were categorized as early (≤30 days) or late (31-90 days). Data were collected from institutional databases as well as Medicare claims. Analysis included 376 BPCI valve patients: 202 open and 174 transcatheter aortic valves (TAVR). TAVR patients were older (83.6 vs 73.8 years; P = 0.001) and had higher Society of Thoracic Surgery predicted risk (7.1% vs 2.8%; P = 0.001). Overall, 18.6% of patients (70/376) had one-or-more 90-day readmission, and total claim was on average 51% greater for these patients. Overall readmissions were more common among TAVR patients (22.4% (39/174) vs 15.3% (31/202), P = 0.052) as was late readmission. TAVR patients had significantly higher late readmission claims, and early readmission was predictive of late readmission for TAVR patients only (P = 0.04). Bundled claims for a 90-day episode of care are significantly increased in patients with readmissions. TAVR patients represent a high-risk group for late readmission, possibly a reflection of their chronic disease processes. Being able to identify patients at highest risk for 90-day readmission and the associated claims will be valuable as we enter into risk-bearing episodes of care agreements with Medicare., (Copyright © 2018 Elsevier Inc.

Background: Venous thromboembolism (VTE) disease prophylaxis rates among medical inpatients have been noted to be <50%., Objective: Our objective was to evaluate the effectiveness and safety of a computerized decision support application to improve VTE prophylaxis., Design: Observational cohort study., Setting: Academic medical center., Patients: Adult inpatients on hospital medicine and nonmedicine services., Intervention: A decision support application designed by a quality improvement team was implemented on medicine services in September 2009., Measurements: Effectiveness and safety parameters were compared on medicine services and nonmedicine (nonimplementation) services for 6-month periods before and after implementation. Effectiveness was evaluated by retrospective information system queries for rates of any VTE prophylaxis, pharmacologic VTE prophylaxis, and hospital-acquired VTE incidence. Safety was evaluated by queries for bleeding and thrombocytopenia rates., Results: Medicine service overall VTE prophylaxis increased from 61.9% to 82.1% (P < 0.001), and pharmacologic VTE prophylaxis increased from 59.0% to 74.5% (P < 0.001). Smaller but significant increases were observed on nonmedicine services. Hospital-acquired VTE incidence on medicine services decreased significantly from 0.65% to 0.42% (P = 0.008) and nonsignificantly on nonmedicine services. Bleeding rates increased from 2.9% to 4.0% (P < 0.001) on medicine services and from 7.7% to 8.6% (P = 0.043) on nonmedicine services, with nonsignificant changes in thrombocytopenia rates observed on both services., Conclusions: An electronic decision support application on inpatient medicine services can significantly improve VTE prophylaxis and hospital-acquired VTE rates with a reasonable safety profile., (Copyright © 2012 Society of Hospital Medicine.)

It has been well established that there are racial and ethnic disparities in cardiovascular care. Quality improvement initiatives have been recommended to proactively address these disparities. An initiative was implemented to improve timeliness of and access to primary percutaneous coronary intervention (PCI) procedures among myocardial infarction patients at an academic medical center serving a predominantly minority population. The effort was part of a national quality improvement collaborative focused on improving cardiovascular care for Hispanic/Latino and African American/ black populations. The proportion of primary PCI procedures performed within 90 minutes improved significantly from 17% in the first quarter of 2006 to 93% in the fourth quarter of 2008 (P < .001). There were no significant differences in the frequency with which Hispanic/Latino or African American/black patients received primary PCI therapy in comparison to nonmembers of these groups. Quality improvement techniques can improve the quality of and access to acute cardiovascular care for minority populations.

The Centers for Medicare & Medicaid Services recently started publicly reporting hospital readmission rates. Health care reform proposals include readmission provisions as vehicles to promote care coordination and achieve savings. Current approaches ascribe variability in hospital readmission primarily to differences in patient medical risk and hospital performance. These approaches do not adequately account for the effect of patient sociodemographic and community factors that influence health care utilization and outcomes. The evidence base on cost-effective and generalizable care management techniques to reduce readmission is still evolving. Although readmission-related policies may prove to be a transformational force in health care reform, their incorrect application in facilities serving vulnerable communities may increase health care system inequity. Policy options can mitigate this potential.

Purpose of Review: The treatment of HIV infection has been transformed by the introduction of highly active antiretroviral therapy. For patients who respond and can tolerate lifelong therapy, HIV infection may become a chronic disease requiring long-term ambulatory care follow-up. The current management of antiretrovirals is increasingly complex because of the large number of agents, wide spectrum of toxicities, adherence issues, and drug interactions. This review summarizes the currently available agents, recommended and alternative combinations, commonly encountered adverse events, and viral resistance issues., Recent Findings: Twenty antiretroviral medications are commercially available in the United States. Six new agents have been introduced since 2000, including one drug in a novel class of HIV fusion inhibitors. The adverse effects of antiretrovirals are well characterized and include lactic acidosis related to nucleoside reverse transcription inhibitors; metabolic and body habitus changes, primarily attributed to protease inhibitors; and concern about the long-term vascular consequences of elevated lipids and insulin resistance associated with treatment. The recommended antiretroviral therapy by an expert panel as of October 2004 is summarized., Summary: The benefits of antiretroviral therapy are clear: reduced morbidity and mortality related to advanced HIV infection. Managing antiretroviral therapy, along with their adverse effects and drug interactions, is complex. Modern treatment mandates a thorough understanding of the agents. Consultation with an HIV-experienced clinician should be considered in most circumstances.

The widespread use of highly active antiretroviral therapy (HAART) since 1996 has led to a substantial decline in morbidity and mortality in patients infected with HIV, although its effect on the incidence of HIV-associated malignancies is unknown. We retrospectively reviewed the annual number of outpatient visits to our HIV clinic, inpatient admissions for HIV disease, and first admissions for patients with cancer and HIV disease at our center between 1990 and 1997. Between 1990 and 1995, there was a progressive increase in the annual number of admissions for HIV disease and HIV-associated cancers that paralleled the increasing HIV clinic volume. In 1997, however, the annual number of first admissions for Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma compared with 1995 decreased by 36% and 63%, respectively, despite a continued increase in the annual number of HIV clinic visits. Similar declines were also noted in the number of new cases of biopsy-confirmed KS and primary central nervous system (CNS) lymphoma. In contrast, there was no decrease in the number of first admissions for patients with HIV infection and other cancers not typically associated with HIV infection. These findings suggest a declining incidence of HIV-associated malignancies since the introduction of HAART.

Background: The incidence of tuberculosis and drug resistance is increasing in the United States, but it is not clear how much of the increase is due to reactivation of latent infection and how much to recent transmission., Methods: We performed DNA fingerprinting using restriction-fragment-length polymorphism (RFLP) analysis of at least one isolate from every patient with confirmed tuberculosis at a major hospital in the Bronx, New York, from December 1, 1989, through December 31, 1992. Medical records and census-tract data were reviewed for relevant clinical, social, and demographic data., Results: Of 130 patients with tuberculosis, 104 adults (80 percent) had complete medical records and isolates whose DNA fingerprints could be evaluated. Isolates from 65 patients (62.5 percent) had unique RFLP patterns, whereas isolates from 39 patients (37.5 percent) had RFLP patterns that were identical to those of an isolate from at least 1 other study patient; the isolates in the latter group were classified into 12 clusters. Patients whose isolates were included in one of the clusters were inferred to have recently transmitted disease. Independent risk factors for having a clustered isolate included seropositivity for the human immunodeficiency virus (HIV) (odds ratio for Hispanic patients, 4.31; P = 0.02; for non-Hispanic patients, 3.12; P = 0.07), Hispanic ethnicity combined with HIV seronegativity (odds ratio, 5.13; P = 0.05), infection with drug-resistant tuberculosis (odds ratio, 4.52; P = 0.005), and younger age (odds ratio, 1.59; P = 0.02). Residence in sections of the Bronx with a median household income below $20,000 was also associated with having a clustered isolate (odds ratio, 3.22; P = 0.04)., Conclusions: In the inner-city community we studied, recently transmitted tuberculosis accounts for approximately 40 percent of the incident cases and almost two thirds of drug-resistant cases. Recent transmission of tuberculosis, and not only reactivation of latent disease, contributes substantially to the increase in tuberculosis.

Effective chemotherapy of tuberculosis requires rapid assessment of drug sensitivity because of the emergence of multidrug-resistant Mycobacterium tuberculosis. Drug susceptibility was assessed by a simple method based on the efficient production of photons by viable mycobacteria infected with specific reporter phages expressing the firefly luciferase gene. Light production was dependent on phage infection, expression of the luciferase gene, and the level of cellular adenosine triphosphate. Signals could be detected within minutes after infection of virulent M. tuberculosis with reporter phages. Culture of conventional strains with antituberculosis drugs, including isoniazid or rifampicin, resulted in extinction of light production. In contrast, light signals after luciferase reporter phage infection of drug-resistant strains continued to be produced. Luciferase reporter phages may help to reduce the time required for establishing antibiotic sensitivity of M. tuberculosis strains from weeks to days and to accelerate screening for new antituberculosis drugs.
