Effect of a Multifaceted Quality Improvement Intervention on Hospital Personnel Adherence to Performance Measures in Patients With Acute Ischemic Stroke in China: A Randomized Clinical Trial.


In China and other parts of the world, hospital personnel adherence to evidence-based stroke care is limited.To determine whether a multifaceted quality improvement intervention can improve hospital personnel adherence to evidence-based performance measures in patients with acute ischemic stroke (AIS) in China.A multicenter, cluster-randomized clinical trial among 40 public hospitals in China that enrolled 4800 patients hospitalized with AIS from August 10, 2014, through June 20, 2015, with 12-month follow-up through July 30, 2016.Twenty hospitals received a multifaceted quality improvement intervention (intervention group; 2400 patients), including a clinical pathway, care protocols, quality coordinator oversight, and performance measure monitoring and feedback. Twenty hospitals participated in the stroke registry with usual care (control group; 2400 patients).The primary outcome was hospital personnel adherence to 9 AIS performance measures, with co-primary outcomes of a composite of percentage of performance measures adhered to, and as all-or-none. Secondary outcomes included in-hospital mortality and long-term outcomes (a new vascular event, disability [modified Rankin Scale score, 3-5], and all-cause mortality) at 3, 6, and 12 months.Among 4800 patients with AIS enrolled from 40 hospitals and randomized (mean age, 65 years; women, 1757 [36.6%]), 3980 patients (82.9%) completed the 12-month follow-up of the trial. Patients in intervention group were more likely to receive performance measures than those in the control groups (composite measure, 88.2% vs 84.8%, respectively; absolute difference, 3.54% [95% CI, 0.68% to 6.40%], P = .02). The all-or-none measure did not significantly differ between the intervention and control groups (53.8% vs 47.8%, respectively; absolute difference, 6.69% [95% CI, -0.41% to 13.79%], P = .06). New clinical vascular events were significantly reduced in the intervention group compared with the control group at 3 months (3.9% vs 5.3%, respectively; difference, -2.03% [95% CI, -3.51% to -0.55%]; P = .007), 6 months (6.3% vs 7.8%, respectively; difference, -2.18% [95% CI, -4.0% to -0.35%]; P = .02) and 12 months (9.1% vs 11.8%, respectively; difference, -3.13% [95% CI, -5.28% to -0.97%]; P = .005).Among 40 hospitals in China, a multifaceted quality improvement intervention compared with usual care resulted in a statistically significant but small improvement in hospital personnel adherence to evidence-based performance measures in patients with acute ischemic stroke when assessed as a composite measure, but not as an all-or-none measure. Further research is needed to understand the generalizability of these findings.ClinicalTrials.gov Identifier: NCT02212912.

Adjunct Associate in the Department of Orthopaedic Surgery

Dr. Bettger’s research is dedicated to establishing real world evidence aimed to improve health care quality and policies that reduce the burden of disease and disability. As a health services researcher and implementation scientist, her research extends from observational studies to randomized and pragmatic trials. She was the Founding Director of Duke Roybal Center for Translational Research in the Behavioral and Social Sciences of Aging and the Founding Director of Undergraduate Initiatives for the Duke-Margolis Center for Health Policy. She has examined implementation of several integrated care models to improve the transition home from the hospital (VERITAS with virtual exercise therapy after knee replacement, COMPASS for stroke, RECOVER for stroke in rural China, and coordinated care for trauma patients in Tanzania). She also studies implementation of community-based models of care that can prevent functional decline. These include the CTSA-funded IMPAC RCT of integrating physical therapists into primary care as first line providers to address musculoskeletal pain, the VA-funded Gerofit program of structured and progressive in-person and virtual group exercise for older Veterans, MRC-funded SINEMA RCT of a village-based model supporting stroke recovery in China, and a NIDCD study comparing three primary care protocols for older adult hearing healthcare.

In addition to the evidence translation studies in China (RECOVER and SINEMA) and Tanzania, she has partnered with experts in Singapore on stroke systems research, and worked on large cluster randomized trials to improve evidence-based care in Brazil, Peru, Argentina (BRIDGE-Stroke) and China (CNSR and Golden Bridge). To address health locally, she was the faculty sponsor to launch Exercise is Medicine at Duke and Help Desk, a student volunteer community resource navigator model addressing social determinants of health.

Dr. Bettger received her BA from the University of Western Ontario, Canada and her MS from the University of Wisconsin–LaCrosse where she studied community reintegration for stroke and brain-injured patients transitioning from hospital to home. Her doctoral training in Rehabilitation Sciences, completed at Boston University, concluded with an investigation of patterns of functional recovery and factors affecting outcomes in patients transitioning home following acute rehabilitation. While working on her doctorate, she also worked in state government as the director of the Paul Coverdell National Acute Stroke Registry. Dr. Bettger completed post-doctoral training at the University of Pennsylvania with a NIH NRSA research fellowship in neurorehabilitation, a research fellowship at the NewCourtland Center for Transitions and Health, and a Switzer Fellowship funded by the National Institute on Disability and Rehabilitation Research to study the role of the environment on functional outcomes. She completed additional research training at Duke as a mentored scholar in comparative effectiveness research funded by AHRQ. As of July 2022, she is an Adjunct Associate Professor for Duke's Department of Orthopaedics and has transitioned out of her role as Co-Director of the Duke Clinical and Translational Institute (CTSA) Pilots Accelerator Core working with NCCU. She is affiliate faculty with Duke's Science and Society, Duke-Margolis Center for Health Policy, the Duke Clinical Research Institute (DCRI) and Duke Global Health Institute (DGHI), is a Senior Fellow of the Duke Center for the Study of Aging and Human Development, and is a Fellow of the American Heart Association.
