    Background and Purpose—Quality of care delivered in the inpatient and ambulatory settings may be correlated within an integrated health system such as the Veterans Health Administration. We examined the correlation between stroke care quality at hospital discharge and within 6 months postdischarge. Methods—We conducted a cross-sectional hospital-level correlation analyses of chart-abstracted data for 3467 veterans discharged alive after an acute ischemic stroke from 108 Veterans Health Administration medical centers and 2380 veterans with postdischarge follow-up within 6 months in fiscal year 2007. Four risk-standardized processes of care represented discharge care quality: prescription of antithrombotic and antilipidmic therapy, anticoagulation for atrial fibrillation, and tobacco cessation counseling along with a composite measure of defect-free care. Five risk-standardized intermediate outcomes represented postdischarge care quality: achievement of blood pressure, low-density lipoprotein, international normalized ratio, and glycosylated hemoglobin target levels, and delivery of appropriate treatment for poststroke depression along with a composite measure of achieved outcomes. Results—Median risk-standardized composite rate of defect-free care at discharge was 79%. Median risk-standardized postdischarge rates of achieving goal were 56% for blood pressure, 36% for low-density lipoprotein, 41% for international normalized ratio, 40% for glycosylated hemoglobin, and 39% for depression management and the median risk-standardized composite 6-month outcome rate was 44%. The hospital composite rate of defect-free care at discharge was correlated with meeting the low-density lipoprotein goal (r=0.31; P=0.007) and depression management (r=0.27; P=0.03) goal but was not correlated with blood pressure, international normalized ratio, glycosylated hemoglobin goals, nor with the composite measure of achieved postdischarge outcomes (probability values >0.13). Conclusions—Hospital discharge care quality was not consistently correlated with ambulatory care quality.

    Estimating and Reporting on the Quality of Inpatient Stroke Care by Veterans Health Administration Medical Centers
    (2012-01) Arling, Greg; Reeves, Mathew; Ross, Joseph S.; Williams, Linda S.; Keyhani, Salomeh; Chumbler, Neale R.; Phipps, Michael S.; Roumie, Christianne L; Myers, Laura J.; Salanitro, Amanda H; Ordin, Diana L.; Myers, Jennifer; Bravata, Dawn M.
    Background—Reporting of quality indicators (QIs) in Veterans Health Administration Medical Centers is complicated by estimation error caused by small numbers of eligible patients per facility. We applied multilevel modeling and empirical Bayes (EB) estimation in addressing this issue in performance reporting of stroke care quality in the Medical Centers. Methods and Results—We studied a retrospective cohort of 3812 veterans admitted to 106 Medical Centers with ischemic stroke during fiscal year 2007. The median number of study patients per facility was 34 (range, 12–105). Inpatient stroke care quality was measured with 13 evidence-based QIs. Eligible patients could either pass or fail each indicator. Multilevel modeling of a patient's pass/fail on individual QIs was used to produce facility-level EB-estimated QI pass rates and confidence intervals. The EB estimation reduced interfacility variation in QI rates. Small facilities and those with exceptionally high or low rates were most affected. We recommended 8 of the 13 QIs for performance reporting: dysphagia screening, National Institutes of Health Stroke Scale documentation, early ambulation, fall risk assessment, pressure ulcer risk assessment, Functional Independence Measure documentation, lipid management, and deep vein thrombosis prophylaxis. These QIs displayed sufficient variation across facilities, had room for improvement, and identified sites with performance that was significantly above or below the population average. The remaining 5 QIs were not recommended because of too few eligible patients or high pass rates with little variation. Conclusions—Considerations of statistical uncertainty should inform the choice of QIs and their application to performance reporting.

    Physician and Other Healthcare Personnel Responses to Hospital Stroke Quality of Care Performance Feedback: A Qualitative Study
    (BMJ, 2016) Ross, Joseph S.; Williams, Linda S.; Damush, Teresa M.; Matthias, Marianne S.; Department of Neurology, IU School of Medicine
    Background Understanding how physicians and other healthcare personnel respond to hospital performance feedback initiatives may have important implications for quality improvement efforts. Our objective was to explore responses to the inaugural feedback of hospital performance on stroke quality of care measures among relevant physicians and personnel at the US Department of Veterans Health Administration (VHA) hospitals. Methods Qualitative interviews with hospital administrators, physicians, nurses and quality managers at 12 VHA hospitals in the USA after the inaugural national release of the report on quality of acute stroke care processes. Interview transcripts were analysed using an immersion/crystallisation approach to identify recurrent themes. Results Interviews were completed with 41 individuals at 12 VHA hospitals from diverse regions of the USA; the majority were clinicians, either physicians or nurses, and nearly all had 20 years of experience or more. Interviewees described general perceptions of internal performance feedback that were both positive and negative, such as the notion that performance feedback could provide value to clinicians and hospitals, but at the same time voiced concerns about being inundated with such data. Interviewees also expressed scepticism about public reporting of performance data, citing numerous concerns and limitations. However, when interviewees described specific experiences with performance feedback, nearly all reactions were positive, including excitement, interest and feeling validated about a job well done. Discussion Physicians and other healthcare personnel described hospital performance feedback on stroke quality of care measures to be broadly valuable but identified areas of concern related to the measurement process and public reporting.
