The Role of Healthcare Professionals in Early Detection and Prevention of Clinical Deterioration Across Hospital Settings Healthcare Professionals and Clinical Deterioration

Abstract

Background. Most in-hospital cardiac arrests, unplanned intensive care admissions and unexpected deaths are preceded by hours of detectable physiological decline. Whether this window is used depends less on technology than on the healthcare professionals who observe, interpret, escalate and respond. Variation in their performance explains much of the variation in failure-to-rescue between hospitals.
Objective. To synthesize evidence on the roles of nurses, physicians, rapid response teams and allied health professionals in the early detection and prevention of clinical deterioration; to examine how these roles differ across hospital settings; to identify the human, team and organizational factors that enable or impede rescue; and to propose an integrated framework for practice and policy.
Methods. Narrative review informed by the SANRA criteria, drawing on MEDLINE, CINAHL, Embase and Scopus, with priority given to systematic reviews, multicenter studies and controlled evaluations of early warning scores, rapid response systems, escalation and digital surveillance.
Results. Aggregate early warning scores such as NEWS discriminate patients at risk of death and unplanned ICU admission well, and rapid response systems are associated with fewer cardiac arrests outside the ICU, with smaller and less consistent effects on mortality. Automated predictive surveillance coupled with structured clinical response has been associated with lower mortality. Benefits, however, depend on the afferent limb: complete observations, nurse concern, timely escalation across hierarchies and an effective response. Staffing, education, psychological safety and interprofessional communication are consistently implicated in failure-to-rescue.
Conclusions. Recognition and rescue of deteriorating patients is an interprofessional competency rather than a tool. The proposed WATCH framework (Watch, Assess and act on concern, Trigger and escalate, Coordinated response, Hardwired learning) aligns roles, processes and system supports across settings, and is applicable to health systems undergoing transformation, including those under Saudi Vision 2030.
