Abstract

Insights

Minimally invasive surgery (MIS) has more technical and organizational safety events than conventional surgery (CS). A specialized technology checklist, not a standard time-out, is needed to improve MIS patient safety.

Area of Science:

  • Surgical Safety
  • Medical Technology Assessment

Background:

  • Patient safety during surgical procedures is critical.
  • Minimally invasive surgery (MIS) and conventional surgery (CS) present different risk profiles.
  • Understanding event frequencies in various risk domains is essential for improving surgical outcomes.

Purpose of the Study:

  • To determine the frequency of patient safety events in different risk domains during MIS and CS.
  • To compare the incidence of these events between MIS and CS.

Main Methods:

  • Observational study of gynecologic MIS and CS procedures.
  • Categorization of observed events into predefined patient safety risk domains.
  • Statistical analysis of event frequencies and relative risks between MIS and CS groups.

Main Results:

  • 53 procedures (26 CS, 27 MIS) were analyzed with comparable general characteristics.
  • Environmental events were frequent (1 per 2.5 min).
  • Technical and organizational events occurred significantly more in MIS than CS (P < 0.01), with relative risks of 1.7 and 4.1 for one or more technical events, respectively. Standard time-out procedures did not correlate with event occurrence.

Conclusions:

  • The inherent technological complexity of MIS increases susceptibility to technology-related problems compared to CS.
  • Standard time-out protocols are insufficient for the complex technology in MIS.
  • Implementing a technology-specific checklist within briefing protocols may reduce MIS-related events.
