Achieving diagnostic excellence through prevention and teamwork (ADEPT) study protocol: a multicenter, prospective quality and safety program to improve diagnostic processes in medical inpatients.
This paper describes the protocol for a study that will build surveillance for hospital diagnostic errors into usual care, benchmark diagnostic performance across sites, pilot test interventions, and evaluate the program's impact on diagnostic error rates. The authors will test achieving diagnostic excellence through prevention and teamwork (ADEPT), a multicenter, real-world quality and safety program utilizing interrupted time-series techniques to evaluate outcomes. They will use a randomly sampled population of medical patients hospitalized at 16 US hospitals who died, were transferred to intensive care, or had a rapid response during the hospitalization. There will be surveillance for diagnostic errors on 10 events per month per site using a previously established two-person adjudication process. With guidance from national experts in quality and safety, study sites will report and benchmark diagnostic error rates, share lessons regarding underlying causes, and design, implement, and pilot test interventions using both Safety I and Safety II approaches aimed at patients, providers, and health systems. The primary outcome sought after will be the number of diagnostic errors per patient, using segmented multivariable regression to evaluate change in y-intercept and change in slope after initiation of the program.

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).

In their own words: safety and quality perspectives from families of hospitalized children with medical complexity.
The purpose of this study was to address the gap of research on inpatient safety/quality experience of Children with medical complexity (CMC) and identify otherwise unrecognized, family-prioritized areas for improving safety/quality of children with medical complexity (CMC). Out of 208 families surveyed, 237 (88%) families completed surveys; 83 families offered 138 free-text safety responses about medications, feeds, cares, and other categories. The study found that themes included unmet expectations of hospital care/environment, lack of consistency, provider-patient communication lapses, families' expertise about care, and the value of transparency.

What works in medication reconciliation: an on-treatment and site analysis of the MARQUIS2 study.
The objective of this study was to assess the association of patient exposure to system-level intervention and receipt based on the results of the second Multicenter Medication Reconciliation Quality Improvement Study, which demonstrated a marked reduction in medication discrepancies per patient. Researchers conducted an on-treatment analysis of system-level interventions at 17 North American hospitals. The patient-level interventions most associated with discrepancy reductions were receipt of a best-possible medication history of admitted patients in the ED and admission and discharge medication reconciliation by a trained clinician. System-level interventions were also associated with a minor reduction in discrepancies for the average patient. The researchers concluded that these findings might be used to help hospitals and health systems prioritize interventions to improve medication safety during care transitions.

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.
