Decreasing Hospital Readmissions Utilizing an Evidence-Based COPD Care Bundle.

PURPOSE: Chronic obstructive pulmonary disease (COPD) is a chronic condition that leads to significant morbidity and mortality. Management of COPD hospitalizations utilizing an evidence-based care bundle can provide consistent quality of care and may reduce readmissions. METHODS: This single-center retrospective cohort study evaluated readmission rates in patients hospitalized with a COPD exacerbation. Patients in the pre-intervention cohort received usual care, while patients in the post-intervention cohort received an innovative inpatient COPD care bundle. The bundle focused on optimizing care in five areas: consults, inpatient interventions, education, transitions of care, and after discharge care. RESULTS: In this study, 149 subjects were included in the pre-intervention cohort and 214 subjects were included in the post-intervention cohort. Thirty-day readmission rates were lower in the post-intervention cohort compared to the pre-intervention cohort, 22.4% vs. 38.3% (p = 0.001). A reduction in 60-day and 90-day readmission rates was also observed, 13.7% vs. 40.3% (p < 0.001) and 10.1% vs. 32.2% (p < 0.001), respectively. CONCLUSION: Bundled care is an effective and inexpensive method for institutions to provide consistent and quality care. The findings of this study demonstrate that the implementation of a COPD care bundle is an effective strategy to decrease hospital readmissions.

The Impact of a Home Respiratory Therapist to Reduce 30-Day Readmission Rates for Exacerbation of COPD.

BACKGROUND: In 2015, the Centers for Medicare and Medicaid Services limited payments to hospitals with high readmission rates for patients admitted with COPD exacerbation. Decreasing readmissions in this patient population improves patient health and decreases health care utilization of resources. We hypothesized a COPD disease management program delivered by a respiratory therapist (RT) in the patient's home may reduce readmission rates for COPD exacerbation. METHODS: We performed a pre/post interventional study comparing hospital readmissions for subjects with COPD exacerbation that received standard of care in the home versus an RT-led home COPD disease management program. Subjects discharged home from Atlantic Health System with COPD exacerbation were enrolled in the pre-intervention group. Subsequently, an evidence-based home COPD disease management program was implemented by an RT from At Home Medical in the home. The home COPD Disease Management Program was implemented from April 2017-September 2019, and this served as the post-intervention group. The primary end point was readmission rates at 30 d. Secondary end points included 60-d and 90-d readmission rates. RESULTS: A total of 1,093 participants were included in the study, 658 in the pre-intervention cohort and 435 participants in the post-intervention group. Approximately 22.3% (n = 147) of subjects in the pre-intervention group was readmitted within 30 d of discharge compared to 12.2% (n = 53) in the post-intervention group (P < .001). A reduction in 60-d (33.9% vs 12.0%, P < .001) and 90-d all-cause readmissions (43.5% vs 13.1%, P < .001) was also seen. Participation in the COPD Disease Management Program was significantly associated with decreased 30-, 60-, and 90-d readmission rates adjusting for age, gender, race, ethnicity, and smoking status (odds ratio 0.48 [95% CI 0.33-0.70]; odds ratio 0.26 [95% CI 0.18-0.38]; odds ratio 0.20 [95% CI 0.14-0.27];P < .001, for all 3 readmission rates). CONCLUSIONS: The COPD Disease Management Program is significantly associated with decreased readmission adjusting for demographics and smoking status.

Forced expiratory time: a composite of airway narrowing and airway closure.

Forced expiratory time (FET) is a spirometrically derived variable thought to reflect lung function, but its physiological basis remains poorly understood. We developed a mathematical theory of FET assuming a linear forced expiratory flow-volume profile that terminates when expiratory flow falls below a defined detection threshold. FET is predicted to correlate negatively with both FEV1 and FVC if variations in the rate of lung emptying (relative to normal) among individuals in a population exceed variations in the amount of lung emptying. We retrospectively determined FET pre- and postmethacholine challenge in 1,241 patients (818 had normal lung function, 137 were obstructed, and 229 were restricted) and examined its relationships to spirometric and demographic variables in both hyperresponsive and normoresponsive individuals. Mean FET was 9.6 ± 2.2 s in the normal group, 12.3 ± 3.0 s in those with obstruction, and 8.8 ± 1.9 s in those with restriction. FET was inversely related to FEV1/FVC in all groups, negatively related to FEV1 in the obstructed patients, and positively related to FVC in both the normal and restricted patients. There was no relationship with methacholine responsiveness. Overall, our theory of the relationship between FET to the spirometric indices is supported by these findings and potentially explains how FET is affected by sex, age, smoking status, and possibly body mass index.NEW & NOTEWORTHY Forced expiratory time (FET) has long been felt to reflect important physiological information about lung function but exactly how has never been clear. Here, we use a model analysis to assess the contributions of airway narrowing versus airway closure to FET in a population of individuals and find support for the theory that FET correlates positively with FEV1 if the amounts of lung emptying over a forced expiration vary from predicted values more than variations in the rates of lung emptying, whereas the correlation is negative in the opposite case.

Effect of carbapenem restriction on prescribing trends for immunocompromised wards at an academic medical center.

The recently described proportion of carbapenem consumption metric was used to assess the effectiveness of formulary restriction for carbapenems for 2 units housing predominantly immunocompromised patients at a large academic medical center. Interrupted time series analysis revealed a significant decrease in meropenem use for hematology-oncology and bone marrow transplant units after restriction.

Knowledge, attitudes, and practices of bedside nursing staff regarding antibiotic stewardship: A cross-sectional study.

BACKGROUND: Nursing engagement in antibiotic stewardship programs (ASPs) remains suboptimal. The purpose of this study was to determine the knowledge, attitudes, and practices of nursing staff members regarding ASPs and identify barriers to their participation in such programs. METHODS: This cross-sectional study was conducted at Virginia Commonwealth University Health System, an 860-bed tertiary care academic center located in Richmond, Virginia, where a well-resourced ASP has been in place for 2 decades. A survey consisting of 12 questions was administered to nursing staff via REDCap (Research Electronic Data Capture) in February 2018. RESULTS: A total of 159 survey responses were included in the study. The results demonstrated gaps in knowledge regarding antibiotic stewardship (AS) and highlighted the importance of improving communication between nurses and ASPs. Overall, 102 (64.15%) of the study participants indicated familiarity with AS. Time constraints and concerns over physician pushback were identified as major barriers to participation. CONCLUSIONS: Many nurses were unaware of our center's ASP. Nurses identified activities falling within their daily workflow as potential areas for contribution to ASPs. Key barriers to participation were also identified. These data will inform efforts to engage nursing in AS activities at our medical center.

Potentially Avoidable Readmissions of Patients Discharged to Post-Acute Care: Perspectives of Hospital and Skilled Nursing Facility Staff.

BACKGROUND: Hospital readmissions from skilled nursing facilities (SNFs) are common. Previous research has not examined how assessments of avoidable readmissions differ between hospital and SNF perspectives. OBJECTIVES: To determine the percentage of readmissions from post-acute care that are considered potentially avoidable from hospital and SNF perspectives. DESIGN: Prospective cohort study. SETTING: One academic medical center and 23 SNFs. PARTICIPANTS: We included patients from a quality improvement trial aimed at reducing hospital readmissions among patients discharged to SNFs. We included Medicare patients who were discharged to one of 23 regional SNFs between January 2013 and January 2015, and readmitted to the hospital within 30 days. MEASUREMENTS: Hospital-based physicians and SNF-based staff performed structured root-cause analyses (RCA) on a sample of readmissions from a participating SNF to the index hospital. RCAs reported avoidability and factors contributing to readmissions. RESULTS: The 30-day unplanned readmission rate to the index hospital from SNFs was 14.5% (262 hospital readmissions of 1,808 discharges). Of the readmissions, 120 had RCA from both the hospital and SNF. The percentage of readmissions rated as potentially avoidable was 30.0% and 13.3% according to hospital and SNF staff, respectively. Hospital and SNF ratings of potential avoidability agreed for 73.3% (88 of the 120 readmissions), but readmission factors varied between settings. Diagnostic problems and improved management of changes in conditions were the most common avoidable readmission factors by hospitals and SNFs, respectively. CONCLUSION: A substantial percentage of hospital readmissions from SNFs are rated as potentially avoidable. The ratings and factors underlying avoidability differ between hospital and SNF staff. These data support the need for joint accountability and collaboration for future readmission reduction efforts between hospitals and their SNF partners.

Can outcomes of intensive care unit patients undergoing tracheostomy be predicted?

OBJECTIVE: To determine whether outcomes (mortality and need for intensive care unit [ICU] readmission) of patients undergoing tracheostomy in the ICU can be predicted by common clinical or historical criteria. METHODS: We conducted a retrospective review of data from the medical record and Project Impact database in a 24-bed medical-surgical ICU in a 500-bed university hospital. In 2004 through 2006, 60 adult patients underwent tracheostomy as part of their ICU management. We classified each patient as either not readmitted, readmitted, died on floor (after ICU discharge), died on first ICU admission, or combined readmitted/died-on-the-floor. Patients who died on the regular floor were significantly heavier than patients discharged without need for readmission (P = .03). Patients with a history of sepsis and those with a history of neurological disease had a tendency toward worse outcomes, but these did not reach statistical significance. CONCLUSIONS: These findings suggest that it is difficult to predict outcomes of patients who undergo tracheostomy in the ICU. Larger and prospective studies may help elucidate this matter.

The Saccharomyces cerevisiae LSB6 gene encodes phosphatidylinositol 4-kinase activity.

The LSB6 gene product was identified from the Saccharomyces Genome Data Base (locus YJL100W) as a putative member of a novel type II phosphatidylinositol (PI) 4-kinase family. Cell extracts lacking the LSB6 gene had a reduced level of PI 4-kinase activity. In addition, multicopy plasmids containing the LSB6 gene directed the overexpression of PI 4-kinase activity in cell extracts of wild-type cells, in an lsb6Delta mutant, in a pik1(ts) stt4(ts) double mutant, and in an pik1(ts) stt4(ts) lsb6Delta triple mutant. The heterologous expression of the S. cerevisiae LSB6 gene in Escherichia coli resulted in the expression of a protein that possessed PI 4-kinase activity. Although the lsb6Delta mutant did not exhibit a growth phenotype and failed to exhibit a defect in phosphoinositide synthesis in vivo, the overexpression of the LSB6 gene could partially suppress the lethal phenotype of an stt4Delta mutant defective in the type III STT4-encoded PI 4-kinase indicating that Lsb6p functions as a PI 4-kinase in vivo. Lsb6p was localized to the membrane fraction of the cell, and when overexpressed, GFP-tagged Lsb6p was observed on both the plasma membrane and the vacuole membrane. The enzymological properties (pH optimum, dependence on magnesium or manganese as a cofactor, the dependence of activity on Triton X-100, the dependence on the PI surface concentration, and temperature sensitivity) of the LSB6-encoded enzyme were very similar to the membrane-associated 55-kDa PI 4-kinase previously purified from S. cerevisiae.
