Virtual Simulation to Reinforce Nursing Staff Resuscitation Responses.

In-hospital cardiac arrests have high mortality rates, increased by delayed resuscitation. Using a single group pre-post interventional design to implement virtual cardiac arrest simulations for medical-surgical units, the purpose of this project was to decrease resuscitation delays and improve self-confidence of the nursing staff. Both response times and confidence improved following virtual simulation. Conducting virtual simulation for resuscitation training may be a valuable alternative to in situ simulation.

The Effect of a System-Level Tiered Huddle System on Reporting Patient Safety Events: An Interrupted Time Series Analysis.

BACKGROUND: The objective of this research was to evaluate the effect of implementing a system-level tiered huddle system (THS) on the reporting of patient safety events into the official event reporting system. METHODS: A quasi-experimental study using interrupted time series was conducted to assess the impact and changes to trends in the reporting of patient safety events pre- (February-July 2020; six months) and post- (September 2020-February 2021; six months) THS implementation within one health care system (238 clinics and 4 hospitals). The severity of harm was analyzed in July 2021 using a modified Agency for Healthcare Research and Quality (AHRQ) harm score classification. The primary outcome measure was the number of patient safety events reported per month. Secondary outcomes included the number of patient safety events reported per month by each AHRQ harm score classification. RESULTS: The system-level THS implementation led to a significant and immediate increase in the total number of patient safety events reported per month (777.73, 95% confidence interval [CI] 310.78-1,244.68, p = 0.004). Similar significant increases were seen for reported numbers of unsafe conditions, near misses, no-harm events that reached patients, and temporary harm (p < 0.05 for each). Reporting of events with permanent harm and deaths also increased but was not statistically significant, likely due to the small number of reported events involving actual harm. CONCLUSION: These findings suggest that system-level THS implementation may increase reporting of patient safety events in the official event reporting system.

Length of Stay, Mortality, Cost, and Perceptions of Care Associated With Transition From an Open to Closed Staffing Model in the Cardiac Intensive Care Unit.

BACKGROUND: Organizational models in the intensive care unit (ICU) have classically been described as either closed or open, depending on the presence or absence of a dedicated ICU team. Although a closed model has been shown to improve patient outcomes in medical and surgical ICUs, the merits of various care models have not been previously explored in the cardiac ICU (CICU) setting. METHODS: From November 2012 to March 2014, data were prospectively collected on all admissions before and after transition from an open to closed CICU at our institution. Baseline clinical variables, illness severity, admission and discharge diagnoses, resource use, and outcomes were recorded. Anonymous surveys were also collected from nursing and resident trainee participants to evaluate the influence of unit structure on perceptions of care. Descriptive statistics were used, and logistic regression modeling was performed to examine the impact of unit structure on mortality. RESULTS: The study consisted of 670 patients, 332 (49.6%) of whom were admitted to the open CICU model and 338 (50.4%) of whom were admitted to the closed model. Neither CICU nor hospital mortality differed between the open and closed units, though length of stay was shorter in the closed CICU. Additionally, nurses and resident trainees reported that the closed CICU allowed for better communication, collaboration, and education. CONCLUSIONS: Although there was no significant impact of unit structure on patient outcomes in this single-center study, the closed CICU model was associated with better perceptions of care.

Putting class IIb recommendations to the test: the influence of unwitnessed and Non-VT/VF arrests on resource consumption and outcomes in therapeutic hypothermia and targeted temperature management.

Therapeutic hypothermia (TH) and targeted temperature management improve neurologic recovery, and survival for patients resuscitated from witnessed out-of-hospital ventricular tachycardia (VT) and ventricular fibrillation (VF) cardiac arrest. The American Heart Association recently gave a class IIb recommendation for the use of TH for non-VT/VF and unwitnessed arrests. We explored changes in baseline characteristics, resource use, and outcomes after expanding indications for TH at our institution based on these guidelines. Fifty-six consecutive patients treated with TH for out-of-hospital cardiac arrest were retrospectively evaluated based on whether they received treatment before (protocol 1) or after (protocol 2) broadening inclusion criteria. In protocol 1, TH was indicated after a witnessed VT/VF arrest. In protocol 2, TH was indicated for unwitnessed arrests, pulseless electrical activity, or asystole. Both populations undergoing TH had similarly extensive medical comorbidities and consumed considerable hospital resources. Overall, 64% of the patients from both protocols died in the hospital, although nominally lower mortality was seen in patients treated under protocol 1 compared with protocol 2 (59% vs. 67%, P = 0.57). Lower mortality was observed after VT/VF than after pulseless electrical activity or asystole (47% vs. 93% vs. 56%, P = 0.017). No patient survived following an unwitnessed arrest, and age (odds ratio per 10 years = 2.59; 95% confidence interval, 1.34-4.81) was independently associated with increased mortality. In an evolving field where best practice is still poorly defined, these data, along with future prospective studies in larger populations, should help to enhance care delivery and optimize cost-effectiveness strategies.
