Summary

A priority-based waiting list system significantly reduces delays for patients awaiting cataract surgery compared to first-come, first-served or triage systems. Deferring admission date decisions maximizes benefits for high-priority patients.

Area of Science:

  • Ophthalmology
  • Healthcare Management
  • Health Services Research

Background:

  • Cataract extraction is a common surgical procedure.
  • Efficient patient scheduling is crucial for timely treatment and resource allocation.
  • Current admission strategies may lead to significant delays for patients, particularly those with higher visual impairment.

Purpose of the Study:

  • To compare the effectiveness of three different patient admission strategies for cataract surgery.
  • To evaluate the impact of visual impairment scoring on reducing patient waiting times.
  • To identify optimal booking systems for prioritizing patients based on visual impairment.

Main Methods:

  • A computer simulation was employed to analyze patient flow over three years.
  • 357 patients awaiting cataract surgery were stratified into three visual impairment groups.
  • Three admission strategies were simulated: first-come, first-served; triage booking; and a priority-based waiting list.

Main Results:

  • Both triage and priority-based waiting list systems reduced priority-weighted delays by 30%-60% compared to first-come, first-served.
  • The priority-based waiting list system, which deferred admission decisions, outperformed the triage system.
  • The effectiveness of delay reduction was influenced by the booking system's initial state (fully booked weeks).

Conclusions:

  • Implementing simple rules for admission dates can substantially reduce delays for high-priority cataract surgery patients.
  • Deferring the admission date decision, rather than booking at outpatient assessment, offers greater benefits in reducing delays.
  • Optimizing booking strategies is essential for improving patient access to timely cataract surgery.
