Project description:Antibiotic prescribing is very common in emergency departments (EDs). Optimal stewardship intervention strategies in EDs are not well defined. We conducted a prospective, observational cohort study in a Veterans Affairs ED in which clinician education and monthly e-mail-based peer comparisons were directed against all oral antibiotic prescribing for discharged patients. Oral antibiotic prescriptions were compared in baseline (June 2016 to December 2017) and intervention (January to June 2018) periods using an interrupted time series regression model. Prescribing appropriateness was compared during January to June 2017 and the intervention period. During the intervention period, antibiotic prescriptions decreased monthly by 10.4 prescriptions per 1,000 ED visits (P = 0.07 [95% confidence interval {CI}, -21.7 to 1.0]). The relative decrease in the trend of antibiotic prescriptions during the intervention period compared to baseline was 9.9 prescriptions per 1,000 ED visits per month (P = 0.07 [95% CI, -20.9 to 1.0]). The intervention was associated with a significant decrease and increase in amoxicillin-clavulanate and cephalexin prescriptions, respectively (P < 0.001, P = 0.004). Decreasing trends in ciprofloxacin prescriptions during the baseline period were maintained during the intervention. Unnecessary antibiotic prescribing (i.e., antibiotic not indicated) decreased from 55.6% to 38.7% during the intervention (30.4% decrease, P = 0.003). Optimal antibiotic prescribing (i.e., antibiotics were indicated, and a guideline-concordant agent was prescribed for guideline-concordant duration) increased by 36% (21.6% to 29.3%, P = 0.12). A peer comparison-based stewardship intervention directed at ED clinicians was associated with reductions in overall and unnecessary oral antibiotic prescribing. There is potential to further improve antibiotic use as suboptimal prescribing remained common.

Project description:Data are needed from outpatient settings to better inform antimicrobial stewardship. In this study, a random sample of outpatient antibiotic prescriptions by primary care providers (PCPs) at our health care system was reviewed and compared to consensus guidelines. Over 12 months, 3,880 acute antibiotic prescriptions were written by 76 PCPs caring for 40,734 patients (median panel, 600 patients; range, 33 to 1,547). PCPs ordered a median of 84 antibiotic prescriptions per 1,000 patients per year. Azithromycin (25.8%), amoxicillin-clavulanate (13.3%), doxycycline (12.4%), amoxicillin (11%), fluoroquinolones (11%), and trimethoprim-sulfamethoxazole (10.6%) were prescribed most commonly. Medical records corresponding to 300 prescriptions from 59 PCPs were analyzed in depth. The most common indications for these prescriptions were acute respiratory tract infection (28.3%), urinary tract infection (23%), skin and soft tissue infection (15.7%), and chronic obstructive pulmonary disease (COPD) exacerbation (6.3%). In 5.7% of cases, no reason for the prescription was listed. No antibiotic was indicated in 49.7% of cases. In 12.3% of cases, an antibiotic was indicated, but the prescribed agent was guideline discordant. In another 14% of cases, a guideline-concordant antibiotic was given for a guideline-discordant duration. Therefore, 76% of reviewed prescriptions were inappropriate. Ciprofloxacin and azithromycin were most likely to be prescribed inappropriately. A non-face-to-face encounter prompted 34% of prescriptions. The condition for which an antibiotic was prescribed was not listed in primary or secondary diagnosis codes in 54.5% of clinic visits. In conclusion, there is an enormous opportunity to reduce inappropriate outpatient antibiotic prescriptions.

Project description:Peer support is a novel strategy to mitigate postintensive care syndrome and postintensive care syndrome-family. This project implemented a peer support program to address postintensive care syndrome for patients and family members. Using a free-flow, unstructured format, a chaplain, social worker, nurse, and intensive care unit survivor led veterans and loved ones in discussion of intensive care unit experiences, fears, and the challenges of recovery. Evaluations indicated group participation is beneficial for emotional support, coping, and understanding common situations related to prolonged intensive care unit stay. A majority reported they would strongly recommend group participation to a friend.

Project description:OBJECTIVE:To compare the effects of two sequential policy changes-the addition of a high-potency statin to the Department of Veterans Affairs (VA) formulary and the release of the American College of Cardiology/American Heart Association (ACC/AHA) cholesterol guidelines-on VA provider prescribing. DATA SOURCES/STUDY SETTING:Retrospective analysis of 1,100,682 VA patients, 2011-2016. STUDY DESIGN:Interrupted time-series analysis of changes in prescribing of moderate-to-high-intensity statins among high-risk patients and across high-risk subgroups. We also assessed changes in prescribing of atorvastatin and other statin drugs. We estimated marginal effects (ME) of formulary and guideline changes by comparing predicted and observed statin use. DATA COLLECTION/EXTRACTION METHODS:Data from VA Corporate Data Warehouse. PRINCIPAL FINDINGS:The use of moderate-to-high-intensity statins increased by 2 percentage points following the formulary change (ME, 2.4, 95% confidence interval [CI], 2.2 to 2.6) and less than 1 percentage point following the guideline change (ME, 0.8, 95% CI, 0.6 to 0.9). The formulary change led to approximately a 12 percentage-point increase in the use of moderate-to-high-intensity atorvastatin (ME, 11.5, 95% CI, 11.3 to 11.6). The relatively greater provider response to the formulary change occurred across all patient subgroups. CONCLUSIONS:Addition of a high-potency statin to formulary affected provider prescribing more than the ACC/AHA guidelines.

Project description:Background:Between 2007 and 2015, inpatient fluoroquinolone use declined in US Veterans Affairs (VA) hospitals. Whether fluoroquinolone use at discharge also declined, in particular since antibiotic stewardship programs became mandated at VA hospitals in 2014, is unknown. Methods:In this retrospective cohort study of hospitalizations with infection between January 1, 2014, and December 31, 2017, at 125 VA hospitals, we assessed inpatient and discharge fluoroquinolone (ciprofloxacin, levofloxacin, moxifloxacin) use as (a) proportion of hospitalizations with a fluoroquinolone prescribed and (b) fluoroquinolone-days per 1000 hospitalizations. After adjusting for illness severity, comorbidities, and age, we used multilevel logit and negative binomial models to assess for hospital-level variation and longitudinal prescribing trends. Results:Of 560219 hospitalizations meeting inclusion criteria as hospitalizations with infection, 37.4% (209602/560219) had a fluoroquinolone prescribed either during hospitalization (32.5%, 182337/560219) or at discharge (19.6%, 110003/560219). Hospitals varied appreciably in inpatient, discharge, and total fluoroquinolone use, with 71% of hospitals in the highest prescribing quartile located in the Southern United States. Nearly all measures of fluoroquinolone use decreased between 2014 and 2017, with the largest decreases found in inpatient fluoroquinolone and ciprofloxacin use. In contrast, there was minimal decline in fluoroquinolone use at discharge, which accounted for a growing percentage of hospitalization-related fluoroquinolone-days (52.0% in 2014; 61.3% by 2017). Conclusions:Between 2014 and 2017, fluoroquinolone use decreased in VA hospitals, largely driven by decreased inpatient fluoroquinolone (especially ciprofloxacin) use. Fluoroquinolone prescribing at discharge, as well as levofloxacin prescribing overall, is a growing target for stewardship.

Project description:Introduction:Opioid overdose is highly prevalent among veterans. The Opioid Safety Initiative (OSI) and Centers for Disease Control and Prevention (CDC) issued prescribing guidelines for managing chronic pain. The purpose of this study was to investigate the impact of the 2013 OSI and 2016 CDC guidelines on opioid-prescribing trends in the emergency department and dental clinic within the Veterans Affairs Salt Lake City Health Care System. Methods:In this retrospective, cohort study, opioid prescriptions were queried from January 1, 2013, through March 31, 2017, and separated into 3 groups: pre-OSI, post-OSI, and post-CDC. The primary outcome was to determine a decrease in opioid prescribing. Secondary outcomes included changes in concurrent benzodiazepine and naloxone prescriptions and prescriber status. Analysis of variance was used to determine a difference between study periods. Results:There were 7339 opioid prescriptions identified. A statistically significant difference was found between the 3 groups in average number of opioids prescribed, morphine milligram equivalents per prescription, days' supplied, and medication quantity per prescription (P?<?.01). There was no significant difference between the 3 groups regarding morphine milligram equivalents per day (P?=?.24). Benzodiazepine prescribing remained the same. Concurrent naloxone prescriptions increased. Discussion:The results demonstrate that days' supply, quantity, and morphine milligram equivalent per day in the post-CDC group were consistent with guideline recommendations. Concurrent naloxone prescribing increased throughout all time periods. Implementation of guidelines impacted opioid-prescribing trends, ultimately lessening potential for misuse and abuse. However, there is still need for improvement with reducing concurrent benzodiazepine prescriptions.

Project description:Little contemporary information is available about comparative performance between Veterans Affairs (VA) and non-VA hospitals, particularly related to mortality and readmission rates, 2 important outcomes of care.To assess and compare mortality and readmission rates among men in VA and non-VA hospitals.Cross-sectional analysis involving male Medicare fee-for-service beneficiaries aged 65 years or older hospitalized between 2010 and 2013 in VA and non-VA acute care hospitals for acute myocardial infarction (AMI), heart failure (HF), or pneumonia using the Medicare Standard Analytic Files and Enrollment Database together with VA administrative claims data. To avoid confounding geographic effects with health care system effects, we studied VA and non-VA hospitals within the same metropolitan statistical area (MSA).Hospitalization in a VA or non-VA hospital in MSAs that contained at least 1 VA and non-VA hospital.For each condition, 30-day risk-standardized mortality rates and risk-standardized readmission rates for VA and non-VA hospitals. Mean aggregated within-MSA differences in mortality and readmission rates were also assessed.We studied 104 VA and 1513 non-VA hospitals, with each condition-outcome analysis cohort for VA and non-VA hospitals containing at least 7900 patients (men; ?65 years), in 92 MSAs. Mortality rates were lower in VA hospitals than non-VA hospitals for AMI (13.5% vs 13.7%, P?=?.02; -0.2 percentage-point difference) and HF (11.4% vs 11.9%, P?=?.008; -0.5 percentage-point difference), but higher for pneumonia (12.6% vs 12.2%, P?=?.045; 0.4 percentage-point difference). In contrast, readmission rates were higher in VA hospitals for all 3 conditions (AMI, 17.8% vs 17.2%, 0.6 percentage-point difference; HF, 24.7% vs 23.5%, 1.2 percentage-point difference; pneumonia, 19.4% vs 18.7%, 0.7 percentage-point difference, all P?<?.001). In within-MSA comparisons, VA hospitals had lower mortality rates for AMI (percentage-point difference, -0.22; 95% CI, -0.40 to -0.04) and HF (-0.63; 95% CI, -0.95 to -0.31), and mortality rates for pneumonia were not significantly different (-0.03; 95% CI, -0.46 to 0.40); however, VA hospitals had higher readmission rates for AMI (0.62; 95% CI, 0.48 to 0.75), HF (0.97; 95% CI, 0.59 to 1.34), or pneumonia (0.66; 95% CI, 0.41 to 0.91).Among older men with AMI, HF, or pneumonia, hospitalization at VA hospitals, compared with hospitalization at non-VA hospitals, was associated with lower 30-day risk-standardized all-cause mortality rates for AMI and HF, and higher 30-day risk-standardized all-cause readmission rates for all 3 conditions, both nationally and within similar geographic areas, although absolute differences between these outcomes at VA and non-VA hospitals were small.

Project description:ImportanceSocioeconomic factors are associated with worse outcomes after hospitalization, but neither the Centers for Medicare & Medicaid Services (CMS) nor the Veterans Affairs (VA) health care system adjust for socioeconomic factors in profiling hospital mortality.ObjectiveTo evaluate changes in Veterans Affairs medical centers' (VAMCs') risk-standardized mortality rates among veterans hospitalized for heart failure and pneumonia after adjusting for socioeconomic factors.Design, setting, and participantsIn this cross-sectional study, retrospective data were used to assess 131 VAMCs' risk-standardized 30-day mortality rates with or without adjustment for socioeconomic covariates. The study population included 42 892 veterans hospitalized with heart failure and 39 062 veterans hospitalized with pneumonia from January 1, 2012, to December 31, 2014. Data were analyzed from March 1, 2019, to April 1, 2020.Main outcomes and measuresThe primary outcome was 30-day mortality after admission. Socioeconomic covariates included neighborhood disadvantage, race/ethnicity, homelessness, rurality, nursing home residence, reason for Medicare eligibility, Medicaid and Medicare dual eligibility, and VA priority.ResultsThe study population included 42 892 veterans hospitalized with heart failure (98.2% male; mean [SD] age, 71.9 [11.4] years) and 39 062 veterans hospitalized with pneumonia (96.8% male; mean [SD] age, 71.0 [12.4] years). The addition of socioeconomic factors to the CMS models modestly increased the C statistic from 0.77 (95% CI, 0.77-0.78) to 0.78 (95% CI, 0.78-0.78) for 30-day mortality after heart failure and from 0.73 (95% CI, 0.72-0.73) to 0.74 (95% CI, 0.73-0.74) for 30-day mortality after pneumonia. Mortality rates were highly correlated (Spearman correlations of ≥0.98) in models that included or did not include socioeconomic factors. With the use of the CMS model for heart failure, VAMCs in the lowest quintile had a mean (SD) mortality rate of 6.0% (0.4%), those in the middle 3 quintiles had a mean (SD) mortality rate of 7.2% (0.4%), and those in the highest quintile had a mean (SD) mortality rate of 8.8% (0.6%). After the inclusion of socioeconomic covariates, the adjusted mean (SD) mortality was 6.1% (0.4%) for hospitals in the lowest quintile, 7.2% (0.4%) for those in the middle 3 quintiles, and 8.6% (0.5%) for those in the highest quintile. The mean absolute change in rank after socioeconomic adjustment was 3.0 ranking positions (interquartile range, 1.0-4.0) among hospitals in the highest quintile of mortality after heart failure and 4.4 ranking positions (interquartile range, 1.0-6.0) among VAMCs in the lowest quintile. Similar findings were observed for mortality rankings in pneumonia and after inclusion of clinical covariates.Conclusions and relevanceThis study suggests that adjustments for socioeconomic factors did not meaningfully change VAMCs' risk-adjusted 30-day mortality rates for veterans hospitalized for heart failure and pneumonia. The implications of such adjustments should be examined for other quality measures and health systems.

Project description:ObjectivesThis study sought to describe clinical and procedural characteristics of veterans undergoing transcatheter aortic valve replacement (TAVR) within U.S. Department of Veterans Affairs (VA) centers and to examine their association with short- and long-term mortality, length of stay (LOS), and rehospitalization within 30 days.BackgroundVeterans with severe aortic stenosis frequently undergo TAVR at VA medical centers.MethodsConsecutive veterans undergoing TAVR between 2012 and 2017 were included. Patient and procedural characteristics were obtained from the VA Clinical Assessment, Reporting, and Tracking system. The primary outcomes were 30-day and 1-year survival, LOS >6 days, and rehospitalization within 30 days. Logistic regression and Cox proportional hazards analyses were performed to evaluate the associations between pre-procedural characteristics and LOS and rehospitalization.ResultsNine hundred fifty-nine veterans underwent TAVR at 8 VA centers during the study period, 860 (90%) by transfemoral access, 50 (5%) transapical, 36 (3.8%) transaxillary, and 3 (0.3%) transaortic. Men predominated (939 of 959 [98%]), with an average age of 78.1 years. There were 28 deaths within 30 days (2.9%) and 134 at 1 year (14.0%). Median LOS was 5 days, and 141 veterans were rehospitalized within 30 days (14.7%). Nonfemoral access (odds ratio: 1.74; 95% confidence interval [CI]: 1.10 to 2.74), heart failure (odds ratio: 2.51; 95% CI: 1.83 to 3.44), and atrial fibrillation (odds ratio: 1.40; 95% CI: 1.01 to 1.95) were associated with increased LOS. Atrial fibrillation was associated with 30-day rehospitalization (hazard ratio: 1.79; 95% CI: 1.22 to 2.63).ConclusionsVeterans undergoing TAVR at VA centers are predominantly elderly men with significant comorbidities. Clinical outcomes of mortality and rehospitalization at 30 days and 1-year mortality compare favorably with benchmark outcome data outside the VA.

Project description:BackgroundThe Veterans Choice Act of 2014 increased the number of Veterans eligible for Department of Veterans Affairs (VA)-purchased care delivered in non-VA community care (CC) facilities. Driving >40 miles from home to a VA facility is a key eligibility criterion for CC. It remains unclear whether this policy change improved geographical access by reducing drive distance for Veterans.ObjectivesDescribe the driving distance for Veterans receiving cataract surgery in VA and CC facilities, and if they visited the closest-to-home facility or if they drove to farther facilities.SubjectsVeterans who had cataract surgery in federal fiscal year 2015.MeasuresWe calculated driving miles to the Closest VA and CC facilities that performed cataract surgeries, and to the location where Veterans received care.ResultsA total of 61,746 Veterans received 83,875 cataract surgeries. More than 50% of CC surgeries occurred farther than the Closest CC facility providing cataract surgery (median Closest CC facility 8.7 miles vs. Actual CC facility, 19.7 miles). Most (57%) Veterans receiving cataract surgery at a VA facility used the Closest VA facility (median Closest VA facility 28.1 miles vs. Actual VA facility at 31.2 miles). In all, 26.1% of CC procedures occurred in facilities farther away than the Closest VA facility.ConclusionsAlthough many Veterans drove farther than needed to get cataract surgery in CC, this was not true for obtaining care in the VA. Our findings suggest that there may be additional reasons, besides driving distance, that affect whether Veterans choose CC and, if they do, where they seek CC.
