Objectives
The primary study objective was to investigate the impact of surveillance monitoring (i.e., continuous monitoring optimized for deterioration detection) on mortality and severe morbidity associated with administration of sedative/analgesic medications in the general care setting. A second objective was consideration of the results in the context of previous investigations to establish practice recommendations for this approach to patient safety.
Methods
Retrospective review of available rescue event and patient safety data from a tertiary care hospital in a rural setting was performed for a 10-year period. Systematic analysis of all adult general care inpatient data followed by chart review for individual patients was used to identify patient death or permanent harm (i.e., ventilator dependency, hypoxic encephalopathy) related to administration of sedative/analgesics.
Results
Of 111,488 patients in units with surveillance monitoring available, none died or were harmed by opioid-induced respiratory depression when surveillance monitoring was in use. One patient died from opioid-induced respiratory depression in a unit where surveillance monitoring was available; however, the patient was not monitored at the time of the adverse event. In unmonitored units (15,209 patients during 29 months of incremental implementation), three patients died from opioid overdose (19.73 deaths per 100,000 at risk patients). The reduced death rate when surveillance monitoring was available (0.0009%) versus not available (0.02%) was significant (
P
= 0.03).
Conclusions
For a 10-year period, the rescue system with continuous surveillance monitoring had a profound effect on death from sedative/analgesic administration in the general care setting. This approach to patient safety can help address the risk of sedative/analgesic-related respiratory arrests in hospitals.
Patient rescue occurs in phases: recognizing the problem, communicating the concern, and treating the complication. To help improve rescue, we sought to understand facilitators and barriers to managing postoperative complications. We used a criterion-based sample from a large academic medical center. Semistructured interviews ( n = 57) were conducted, which were audio-recorded and transcribed verbatim. Thematic analysis and consensus coding was performed using NVivo 11. We used a framework matrix approach to synthesize our coding and identify themes that facilitate or impede rescue. Clinicians identified root causes for delays in care, such as recognizing patient deterioration, knowing whom to contact and when, and reaching the correct decision-making provider. This study identified significant variation in communication processes across providers caring for surgical patients. Targeted interventions aimed at improving and standardizing these aspects of communication may significantly influence the ability to effectively identify and escalate care for postoperative complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
