Current patient safety flags overlook common adverse events (AEs). Prioritizing AEs by resource use and outcome reveals that minor disabilities consume the most resources, highlighting the need to address both severe and mundane problems.

Area of Science:

  • Healthcare quality and safety
  • Health services research
  • Patient safety

Background:

  • Existing adverse event (AE) detection systems prioritize severe outcomes.
  • This focus may neglect common, less severe AEs that significantly impact resource utilization.

Purpose of the Study:

  • To establish a framework for prioritizing patient safety improvements.
  • To rank adverse events based on resource consumption and patient outcomes.
  • To classify AEs into Principal Natural Categories (PNCs) for targeted intervention.

Main Methods:

  • Analysis of adverse events (AEs) from a sample of Australian acute care hospital admissions.
  • Classification of AEs into Principal Natural Categories (PNCs).
  • Ranking of PNCs by frequency, resource consumption (mean hospital stay, case numbers), and outcome severity.

Main Results:

  • 1712 AEs were categorized into 581 PNCs; 72% had two or fewer cases.
  • 60% of resource use stemmed from AEs causing minor disabilities.
  • AEs with serious outcomes were concentrated in fewer than 50 PNCs, with only seven having over six severe cases.

Conclusions:

  • Interventions based solely on serious outcomes miss the majority of resource-consuming AEs.
  • Addressing both severe and common AEs is crucial for comprehensive patient safety.
  • Most AE types occur too infrequently for hospital-level analysis, necessitating large-scale data collection.
