Wait times for breast cancer care

Area of Science:

• Oncology
• Health Services Research
• Cancer Care Delivery

Background:

• Measuring care time intervals in cancer treatment is complex and can be influenced by various factors.
• The definition of the monitored care interval can significantly bias the detection of changes in patient wait times.
• Understanding these complexities is vital for effective cancer care management.

Purpose of the Study:

• To examine the implications of using different care interval definitions for reporting wait times.
• To identify delays in cancer care provision by analyzing various time intervals.
• To assess how different resolutions of care intervals affect the identification of treatment delays.

Main Methods:

• Retrospective chart review of 637 women with surgically treated breast cancer.
• Analysis of patient data referred to a cancer centre between September 1999-2000 and September 2003-2004.
• Comparison of wait times using different care interval definitions (low, intermediate, and high resolution).

Main Results:

• Overall waits between detection and adjuvant treatment increased by 12 days over the study periods.
• Higher-resolution intervals identified specific delays: 4 days in accessing surgery and 4 days in receiving adjuvant chemotherapy.
• Delays in adjuvant chemotherapy were missed when using intermediate (referral to adjuvant treatment) and low (detection to adjuvant treatment) resolution intervals.
• Disease stage and type of first adjuvant treatment significantly influenced wait times.

Conclusions:

• Comprehensive monitoring of the entire cancer care pathway is essential for accurate delay identification.
• Higher-resolution interval analysis is necessary to pinpoint specific bottlenecks in cancer care delivery.
• Effective prioritization of interventions and optimization of cancer care access require detailed pathway monitoring.
