Risk-adjusted cumulative sum for early detection of hospitals with excess perioperative mortality.
This study’s goal was to compare the risk-adjusted cumulative sum (CUSUM) with episodic evaluation for early detection of hospitals with excess perioperative mortality. The study cohort included 697,566 patients treated at 104 Veterans’ Affairs hospitals across 24 quarters with a mean age of 60.9 years and 91.4% male. These patients underwent a noncardiac operation at a Veterans Affairs hospital, had a record in the Veterans Affairs Surgical Quality Improvement Program (January 1, 2011, through December 31, 2016), and were aged 18 years or older. For each hospital, the median number of quarters detected with observed to expected ratios, at least 1 CUSUM signal, and more than 1 CUSUM signal was 2 quarters (IQR, 1-4 quarters), 8 quarters (IQR, 4-11 quarters), and 3 quarters (IQR, 1-4 quarters). Outlier hospitals were identified 33.3% of the time (830 quarters) with at least 1 CUSUM signal within a quarter, 12.5% (311 quarters) with more than 1 CUSUM signal, and 11.0% (274 quarters) with observed to expected ratios at the end of the quarter. The CUSUM detection occurred a median of 49 days (IQR, 25-63 days) before observed to expected ratio reporting (1 signal, 35 days [IQR, 17-54 days]; 2 signals, 49 days [IQR, 26-61 days]; 3 signals, 58 days [IQR, 44-69 days]; ≥4 signals, 49 days [IQR, 42-69 days]. Of 274 hospital quarters detected with observed to expected ratios, 72.6% were concurrently detected by at least 1 CUSUM signal vs 42.7% by more than 1 CUSUM signal. There was a dose-response relationship between the number of CUSUM signals in a quarter and the median observed to expected ratio (0 signals, 0.63; 1 signal, 1.28; 2 signals, 1.58; 3 signals, 2.08; ≥4 signals, 2.49).

Changes in surgical outcomes in a Statewide Quality Improvement Collaborative with introduction of simultaneous, comprehensive interventions.
Researchers investigated whether a comprehensive quality improvement program implemented simultaneously across hospitals at the formation of a quality improvement collaborative (QIC) would improve patient outcomes. They analyzed risk-adjusted rates of postoperative morbidity and mortality for patients who had undergone surgery at hospitals in the Illinois Surgical Quality Improvement Collaborative (ISQIC); analyses compared ISQIC hospitals with hospitals in the NSQIP Participant Use File (PUF). Although complication rates decreased at both ISQIC and PUF hospitals, findings showed that participation in ISQIC was associated with a significantly greater improvement in death or serious morbidity. The researchers concluded that these results emphasize the potential of QICs to improve patient outcomes.

Development of the Illinois Surgical Quality Improvement Collaborative (ISQIC): implementing 21 components to catalyze statewide improvement in surgical care.
In 2014, a distinctive learning collaborative was established by 56 hospitals in Illinois, known as the Illinois Surgical Quality Improvement Collaborative (ISQIC). The purpose of this study is to present an overview of ISQIC's initial three years, focusing on 1) the formation and financing of the collaborative, 2) the 21 approaches employed for quality improvement (QI) support, 3) maintaining the collaborative, and 4) ISQIC as a foundation for innovative QI research. ISQIC integrates 21 elements that promote QI, targeting the hospital, the surgical QI team, and the perioperative microsystem. These elements were derived from existing evidence, a comprehensive needs assessment of the hospitals, previous experiences from surgical and non-surgical QI collaboratives, and interviews with QI professionals. The elements span five domains: guided implementation (e.g., mentors, coaches, statewide QI projects), education (e.g., process improvement (PI) curriculum), comparative performance reports for hospitals and surgeons (e.g., process, outcomes, costs), networking (e.g., venues for sharing QI experiences and best practices), and financing (e.g., for the overall program, pilot grants, and incentive payments for improvement). The study found that the 21 unique ISQIC components enabled hospitals to utilize their data effectively for the implementation of QI initiatives and enhancement of care. Formal (QI/PI) training, mentorship, and coaching were provided to hospitals as they implemented solutions. Hospitals were funded for the program and collaborated on statewide quality initiatives. Knowledge gained in one hospital was disseminated to all participating hospitals through conferences, webinars, and toolkits, fostering a collective learning environment aimed at improving and ensuring safer care for surgical patients in Illinois. Over the first three years, surgical outcomes in Illinois showed improvement.

Rescue Improvement Conference: a novel tool for addressing failure to rescue.
The objective of this study was to understand the effectiveness of the Rescue Improvement Conference, a forum that addresses failure to rescue (FTR). FTR is the phenomenon where delayed recognition or response to surgical complications leads to a progressive cascade of adverse events culminating in patient death. The authors used 5 indicators of effectiveness: educational value, conference takeaways, discussion time, changes to surgical practice, and opportunities for improvement and conducted semi-structured interviews. The results showed that conference felt that the Rescue Improvement Conference was effective in all five indicators. The authors concluded that the conference has the potential to support other surgical departments in developing system-level strategies to recognize and manage postoperative complications that contribute to FTR.
