Association Between Hospital Process Composite Performance and Patient Outcomes After In-Hospital Cardiac Arrest Care.

ABSTRACT:

Importance

Survival rates after in-hospital cardiac arrest (IHCA) vary significantly among US centers; whether this variation is owing to differences in IHCA care quality is unknown.

Objective

To evaluate hospital-level variation to determine whether hospital process composite performance measures of IHCA care quality are associated with patient outcomes.

Design, setting, and participants

Using data from the American Heart Association's Get With the Guidelines-Resuscitation (GWTG-R) program, we analyzed 35 283 patients 18 years or older with IHCA treated at 261 US hospitals from January 1, 2010, through December 31, 2012. We calculated the hospital process composite performance score for IHCA using 5 guideline-recommended process measures. Opportunity-based scores were calculated for all patients, aggregated at the hospital level, divided into quartiles, and then associated with risk-standardized survival and neurologic status by a test for trend. The scores were then evaluated through hierarchical logistic regression and reported as odds ratios per 10% increment in hospital process composite performance.

Interventions

Acute care treatments for IHCA.

Main outcomes and measures

The primary outcome was survival to discharge measured as risk standard survival rates, and the secondary outcome was favorable neurologic status at hospital discharge.

Results

Of the 35 283 adults included in this study, the median age was 67 years (interquartile range [IQR] 56-78 years), and 57.9% were male. The median IHCA hospital process composite performance was 89.7% (interquartile range, 85.4%-93.1%) and varied among hospital quartiles from 82.6% (lowest) to 94.8% (highest). The IHCA hospital process composite performance was linearly associated with risk-standardized hospital survival to discharge rates: 21.1%, 21.4%, 22.8%, and 23.4% from lowest to highest performance quartiles, respectively (P < .001). After adjustment, each 10% increase in a hospital's process composite performance was associated with a 22% higher odds of survival (adjusted odds ratio, 1.22; 95% CI, 1.08-1.37; P = .01). Hospital process composite quality performance was also associated with favorable neurologic status at discharge (P = .004).

Conclusions and relevance

The quality of guideline-based care for IHCA varies significantly among US hospitals and is associated with patient survival and neurologic outcomes.

Project description:Background Identifying actionable resuscitation practices that vary across hospitals could improve adherence to process measures or outcomes after in-hospital cardiac arrest (IHCA). We sought to examine whether hospital debriefing frequency after IHCA varies across hospitals and whether hospitals which routinely perform debriefing have higher rates of process-of-care compliance or survival. Methods We conducted a nationwide survey of hospital resuscitation practices in April of 2018, which were then linked to data from the Get With The Guidelines-Resuscitation national registry for IHCA. Hospitals were categorized according to their reported frequency of debriefing immediately after IHCA; rarely (0%-20% of all IHCA cases), occasionally (21%-80%), and frequently (81%-100%). Hospital-level rates of timely defibrillation (≤2 minutes), epinephrine administration (≤5 minutes), survival to discharge, return of spontaneous circulation, and neurologically intact survival were comparted for patients with IHCA from 2015 to 2017. Results Overall, there were 193 hospitals comprising 44 477 IHCA events. Mean patient age was 65±16, 41% were females, and 68% were of White race. Across hospitals, 84 (43.5%) rarely performed debriefings immediately after an IHCA, 82 (42.5%) performed debriefing sessions occasionally, and 27 (14.0%) performed debriefing frequently. There was no association between higher reported debriefing frequency and hospital rates of timely defibrillation and epinephrine administration. Mean hospital rates of risk-standardized survival to discharge were similar across debriefing frequency groups (rarely 25.6%; occasionally 26.0%; frequently 25.2%, P=0.72), as were hospital rates of risk-adjusted return of spontaneous circulation (rarely 72.2%; occasionally 73.0%; frequently 70.0%, P=0.06) and neurologically intact survival (rarely 21.9%, occasionally 22.2%, frequently 21.1%, P=0.75). Conclusions In a large contemporary nationwide quality improvement registry, hospitals varied widely in how often they conducted debriefings immediately after IHCA. However, hospital debriefing frequency was not associated with better adherence to timely delivery of epinephrine or defibrillation or higher rates of IHCA survival.

Project description:BackgroundMaternal in-hospital cardiac arrest is a rare event with the potential for resuscitation treatment delays because of the difficulty accessing hospital obstetrical units and limited simulation training or resuscitation experience of obstetrical staff. However, it is unclear whether survival rates and processes of care differ between women with a maternal in-hospital cardiac arrest and those with a nonmaternal in-hospital cardiac arrest.ObjectiveWe aimed determine whether to there are delays in process measures and differences in survival outcomes between pregnant and nonpregnant women who have in-hospital cardiac arrest.Study designUsing data from 2000 to 2019 in the Get With The Guidelines-Resuscitation registry, we compared resuscitation outcomes between women aged 18 to 50 years with a maternal or nonmaternal in-hospital cardiac arrest. Using a nonparsimonious propensity score, we matched patients with a maternal in-hospital cardiac arrest to as many as 10 women with a nonmaternal in-hospital cardiac arrest. We constructed conditional logistic regression models to compare survival outcomes (survival to discharge, favorable neurologic survival [discharge cerebral performance score of 1], and return of spontaneous circulation) and processes of care (delayed defibrillation [>2 minutes] and administration of epinephrine [>5 minutes]) between women with a maternal in-hospital cardiac arrest vs those with a nonmaternal in-hospital cardiac arrest.ResultsOverall, 421 women with a maternal in-hospital cardiac arrest were matched by propensity score to 2316 women with a nonmaternal in-hospital cardiac arrest. The mean age among propensity score-matched women with a maternal in-hospital cardiac arrest was 31.4 (standard deviation, 6.5) years, where 33.7% were of Black race and 86.9% had an initial nonshockable cardiac arrest rhythm. Unadjusted survival rates were higher in women with a maternal in-hospital cardiac arrest than in women with a nonmaternal in-hospital cardiac arrest: survival to discharge of 45.1% vs 26.5%, survival with cerebral performance category 1 status of 36.1% vs 17.7%, and return of spontaneous circulation of 75.8% vs 70.6%. After adjustment, there was no difference in the likelihood of survival to discharge (odds ratio, 1.19; 95% confidence interval, 0.82-1.73) or return of spontaneous circulation (odds ratio, 0.94; 95% confidence interval, 0.65-1.35) between women with a maternal in-hospital cardiac arrest and those with a nonmaternal in-hospital cardiac arrest. However, women with a maternal in-hospital cardiac arrest were more likely to have favorable neurologic survival (odds ratio, 1.57; 95% confidence interval, 1.06-2.33). Compared with women with a nonmaternal in-hospital cardiac arrest, women with a maternal in-hospital cardiac arrest had similar rates of delayed defibrillation (42.5% vs 34.4%; odds ratio, 1.14 [95% confidence interval, 0.41-3.18]; P=.31) and delayed administration of epinephrine (13.8% vs 10.6%; odds ratio, 0.96 [95% confidence interval, 0.50-1.86]; P=.09).ConclusionAlthough concerns have been raised about resuscitation outcomes in women with a maternal in-hospital cardiac arrest, the rates of survival and resuscitation processes of care were not worse in women with a maternal in-hospital cardiac arrest.

Project description:STUDY OBJECTIVE:It is unknown whether regionalization of postarrest care by interfacility transfer to cardiac arrest receiving centers reduces mortality. We seek to evaluate whether treatment at a cardiac arrest receiving center, whether by direct transport or early interfacility transfer, is independently associated with long-term outcome. METHODS:We performed a retrospective cohort study including adults resuscitated from out-of-hospital cardiac arrest in southwestern Pennsylvania and neighboring Ohio, West Virginia, and Maryland, which includes approximately 5.7 million residents in urban, suburban, and rural counties. Patients were treated by 1 of 78 ground emergency medical services agencies or 2 air medical transport agencies between January 1, 2010, and November 30, 2014. Our primary exposures of interest were interfacility transfer to a cardiac arrest receiving center within 24 hours of arrest or any treatment at a cardiac arrest receiving center regardless of transfer status. Our primary outcome was vital status, assessed through December 31, 2014, with National Death Index records. We used unadjusted and adjusted survival analyses to test the independent association of cardiac arrest receiving center care, whether through direct or interfacility transport, on mortality. RESULTS:Overall, 5,217 cases were observed for 3,629 person-years, with 3,865 total deaths. Most patients (82%) were treated at 42 non-cardiac arrest receiving centers with median annual volume of 17 cases (interquartile range 1 to 53 cases per center annually), whereas 18% were cared for at cardiac arrest receiving centers receiving at least 1 interfacility transfer per month. In adjusted models, treatment at a cardiac arrest receiving center was independently associated with reduced hazard of death compared with treatment at a non-cardiac arrest receiving center (adjusted hazard ratio 0.84; 95% confidence interval 0.74 to 0.94). These effects were unchanged when analysis was restricted to patients brought from the scene to the treating hospital. No other hospital characteristic, including total out-of-hospital cardiac arrest patient volume and cardiac catheterization capabilities, independently predicted outcome. CONCLUSION:Both early interfacility transfer to a cardiac arrest receiving center and direct transport to a cardiac arrest receiving center from the scene are independently associated with reduced mortality.
