Area of Science:

  • Healthcare research methodology
  • Patient safety studies
  • Hospital quality improvement

Background:

  • Adverse events (AEs) pose a significant challenge to patient safety in healthcare.
  • Understanding the occurrence, causation, and prevention of AEs is crucial for improving healthcare quality.
  • Previous research on AEs in New Zealand public hospitals has been limited.

Purpose of the Study:

  • To evaluate the feasibility of conducting research on adverse events (AEs) in New Zealand public hospitals.
  • To determine if current methodologies meet international standards for AE research.
  • To assess the potential for future research into AE occurrence, causation, and prevention in this setting.

Main Methods:

  • A two-stage retrospective review of 1,575 medical records from 1995 admissions in three Auckland public hospitals.

  • Systematic list sampling for record selection, followed by structured implicit review using a standardized protocol.
  • Feasibility assessment based on international benchmarks, including sample selection, record completeness, reviewer agreement (kappa scores, predictive values), and validity of AE determination and preventability criteria.

    • Main Results:

    • The sample selection process was effective, despite a 10% record non-retrieval rate.
    • Medical records contained sufficient information for AE identification and analysis.
    • Adequate inter-rater reliability was achieved for screener and reviewer judgments (kappa 0.302-0.622).
    • AE determination and preventability criteria demonstrated internal consistency and face validity.

    Conclusions:

    • Research investigating the occurrence, causation, and prevention of adverse events in New Zealand healthcare settings is methodologically feasible.
    • The study's methods align with international benchmark standards for AE research.
    • Findings support the initiation of comprehensive research into patient safety and adverse events in New Zealand public hospitals.
