Area of Science:

  • General Surgery
  • Health Policy
  • Surgical Waiting Lists

Background:

  • New Zealand health reforms introduced an arbitrary 6-month waiting time threshold for surgery.
  • This study examines elective general surgery waiting times across different diagnoses.
  • Investigates the relationship between diagnoses and established waiting time thresholds.

Purpose of the Study:

  • To analyze variations in elective general surgery waiting times based on diagnosis.
  • To understand how different surgical conditions interact with waiting time policies.
  • To evaluate the impact of arbitrary waiting time thresholds on patient access to surgery.

Main Methods:

  • Survival curve analysis of 918 patients on elective general surgical waiting lists.
  • Data collected from a tertiary hospital in New Zealand prior to waiting time threshold implementation.

  • Hazard function analysis at 180, 360, and 540 days for various diagnoses.

    • Main Results:

    • Significant differences in waiting times were observed for malignancy, cholelithiasis, hernias, and anorectal diseases (P < 0.001).
    • Patients with malignancy experienced near-zero waiting times by 360 days.
    • Hernias, anorectal diseases, and cholelithiasis showed longer waiting times, extending to 540 days.

    Conclusions:

    • Waiting times for elective surgery vary significantly by diagnosis.
    • A universal waiting time threshold for all elective surgeries is not evidence-based.
    • Surgical waiting list policies should consider diagnostic-specific needs.
