Abstract

Insights

Patients seeking Mohs micrographic surgery for skin cancer in Ontario face long wait times, averaging 17.5 weeks. This delay exceeds recommended cancer treatment standards, highlighting a need for improved access to this specialized dermatologic surgery.

Area of Science:

  • Dermatology
  • Surgical Oncology
  • Health Services Research

Background:

  • Ontario's Ministry of Health and Long-Term Care tracks cancer surgery wait times, but excludes skin cancer procedures.
  • Current data collection does not encompass wait times for Mohs micrographic surgery, a key treatment for skin cancer.

Purpose of the Study:

  • To evaluate wait times and referral patterns for Mohs micrographic surgery at The Ottawa Hospital.
  • To assess the accessibility of skin cancer treatment within Ontario.

Main Methods:

  • Retrospective review of 101 Mohs surgeries (96 patients) performed at The Ottawa Hospital between June and October 2010.
  • Calculation of the interval between referral receipt and surgery date.
  • Recording of referring physician specialty and patient postal codes.

Main Results:

  • The average wait time for Mohs surgery was 122.6 days (17.5 weeks), with a median of 124 days.
  • Over 75% of patients experienced wait times exceeding 12 weeks (84 days).
  • All treated patients resided in eastern and northern Ontario postal districts.

Conclusions:

  • Wait times for Mohs surgery in the Ottawa region surpass established cancer treatment standards.
  • Integrating Mohs surgery into the Ministry of Health and Long-Term Care's Wait Time Strategy could enhance patient access to care.
