Braun EJ, Singh S, Penlesky AC, et al. BMJ Qual Saf. 2022;Epub Apr 15.
Early warning systems (EWS) use patient data from the electronic health record to alert clinicians to potential patient deterioration. Twelve months after a new EWS was implemented in one hospital, nurses were interviewed to gather their perspectives on the program experience, utility, and implementation. Six themes emerged: timeliness, lack of accuracy, workflow interruptions, actionability of alerts, underappreciation of core nursing skills, and opportunity cost.

Situation awareness supports effective teamwork and safe care delivery. This commentary highlights the role of situation awareness in watching the condition of pediatric inpatients to reduce instances of unrecognized clinical deterioration. It features rapid response models enhanced by event review, psychological safety, and patient and family partnering as mechanisms improved through situation awareness.

People of color experience disproportionately higher rates of maternal morbidity and mortality. As part of a larger quality improvement and patient safety initiative to reduce severe maternal morbidity from hemorrhage (SMM-H), this hospital analyzed administrative data stratified by race and ethnicity, and noted a disparity between White and Black patients. Review of this data was integrated with the overall improvement bundle. Post-implementation results show that SMM-H rates for Black patients decreased.

Critical incident reporting is an important method to detect patient safety hazards and improve care. A research team in one large UK tertiary hospital reviewed cardiac arrest calls and cardiopulmonary resuscitation (CPR) events reported to the hospital incident reporting system; ten thematic areas for potential improvement were identified (e.g., failure to rescue, staffing concerns, equipment/drug concerns). Organizations could replicate this longitudinal process to improve high-risk patient safety event outcomes.

Rapid response (RR) systems are used to improve clinical outcomes and prevent transfer to ICU of patients demonstrating signs of rapid deterioration. To evaluate its RR system, one hospital’s pediatric department reviewed all REACT (Rapid Escalation After Critical Transfer) events (i.e., cardiopulmonary arrest and/or ventilation and/or hemodynamic support) which occurred within 24 hours of the RR. These reviews identified opportunities for systemwide improvements.

Rapid response systems (RRS) are widely used to identify signs of rapid deterioration among hospitalized patients.  Using in situ simulation, researchers identified obstacles to effective RRS execution, including inconsistent education and documentation, lack of interpersonal trust, and low psychological safety.

Failure to rescue refers to delayed or missed recognition of a potentially fatal complication that results in a patient’s death. This single-center study sought to more effectively manage deteriorating patients after emergency surgery and reduce failure to rescue rates. Researchers used the functional resonance analysis method (FRAM) to develop recommendations for strengthening organizational resilience. Recommendations included improving team communication, organizational learning, and relationships.

Patient safety indicators (PSI) are measures that focus on quality of care and potentially preventable adverse events. This study estimated odds of preventable mortality of older adults with traumatic injuries and identified the PSIs that are associated with the highest level of preventable mortality.  Strategies to reduce preventable mortality in older adults are presented (e.g. utilization of national guidelines, minimization of central venous catheter use, addressing polypharmacy).

Situation awareness refers to the degree to which perception matches reality. This narrative review explored how situation awareness has been defined and studied in healthcare, with a particular focus on nursing. Three overarching themes were identified: (1) individual, team and systems perspectives of situation awareness; (2) situation awareness and patient safety, and (3) communication tools, technologies and education to support situation awareness. The authors note that future research should reflect nurse’s work and the constrictions imposed on situation awareness by the demands of busy impatient wards.

Failure to identify and prevent clinical deterioration can reflect the quality and effectiveness of care. This study used routinely collected emergency event data to identify failure to rescue events at one tertiary children’s hospital. Over a nine-year period, 520 emergency events were identified; 25% were cardiac arrest events and 60% occurred among patients who had been admitted for more than 48 hours. Over the nine-year period, failure to rescue events decreased from 23.6% to 2.5%.

Many strategies have been developed to improve recognition of, and response, to clinically deteriorating patients. This review found that simulation-based educational strategies was the most effective educational method for training staff to recognize unwell patients. However, the quality of evidence was low and additional research into simulation-based education is needed.

Failure to rescue, the delayed or missed recognition of a potentially fatal complication that results in the patient’s death, is particularly tragic in obstetric care. Using the Systems Engineering Initiative for Patient Safety (SEIPS) framework, the authors describe the work system, process, and outcomes related to failure to rescue, and develop intervention theories.

A seven-year-old girl with esophageal stenosis underwent upper endoscopy with esophageal dilation under general anesthesia. During the procedure, she was fully monitored with a continuous arterial oxygen saturation probe, heart rate monitors, two-lead electrocardiography, continuous capnography, and non-invasive arterial blood pressure measurements.

Rapid response teams (RRTs) are intended to quickly identify clinical deterioration and prevent intensive care unit transfer, cardiac arrest, or death. This article summarizes the evidence included in the AHRQ Making Healthcare Safer III report about the use of RRTs to decrease failure to rescue. Although utilization is widespread, the authors conclude that definitive evidence that RRTs are associated with reduced rates of failure to rescue is inconclusive. The authors note that evidence does support that RRTs are associated with reduced secondary outcomes, such as ICU transfer rate and cardiac arrest.

Artificial Intelligence (AI) is used across healthcare settings to address a variety of patient safety targets. This scoping review evaluated the potential of AI to improve patient safety across eight domains including adverse drug events, decompensation, and diagnostic errors. Both traditional (e.g. EHR) and novel (e.g. wearables) data sources can be used to develop models and interventions to improve patient safety.

Lack of communication and interpersonal dynamics can contribute to failure to rescue. This study surveyed 262 surgical staff about perceived safety climate, but the authors did not find an association between organizational safety culture and failure to rescue or inpatient mortality.  
Dykes PC, Lowenthal G, Faris A, et al. J Patient Saf. 2021;17:56-62.
Failure to rescue – the lack of adequate response to patient deterioration – has been associated with adverse patient outcomes, particularly in acute care settings. This article describes two health systems’ efforts to implement in-hospital Clinical Monitoring System Technology (CMST) which positively impacted failure-to-rescue events. The authors identified barriers and facilitators to CMST use, which informed the development of an implementation toolkit addressing readiness, implementation, patient/family introduction, champions, and troubleshooting.

Anesthesiology critical events are uncommon, and yet they have great potential for harm. This special issue focuses on management of, and preparation for, perioperative critical events and rescue should they occur. The authors highlight simulation training, debriefing, and cognitive aids as methods for improving safety in the operating room.

The anesthesia community has been a leader in patient safety innovation for over four decades. This conference summary highlights presented content related to the conference theme of “preventing, detecting, and mitigating clinical deterioration in the perioperative period.” The results of a human-centered design analysis exploring tactics to reduce failure to rescue were summarized.

Although rapid response programs have been advocated as promising patient safety strategies, the evidence regarding their benefits is mixed. This review provides an overview of rapid response systems, including key components and goals of the intervention. Further research is needed to provide justification on their use for adult patients.
