Abstract 87: Time From Symptom Development to Care Milestones at the Only Public Oncology Clinic in Belize

Abstract

Abstract Purpose: Belize is a middle-income Caribbean country with a fragmented healthcare system. In 2018, the first and only public medical oncology clinic was opened through a capacity building partnership with the Ministry of Health. Little is known about the country’s referral infrastructure for cancer. Here we report on the stage at presentation to the clinic, and the time from symptom development to various care milestones (biopsy, oncology clinic visit, chemo, upfront surgery), referred to as time-to-care, to establish a base timeline. Methods: We performed a retrospective review of available data at the Karl Heusner Memorial Hospital (KHMH) oncology clinic from 2018 - 2022, gathering cancer type, stage, and the dates of care milestones (biopsy, initial clinic visit, chemo, upfront surgery). Date of symptom development was consistently documented by the treating physician (RY). Results: The most common presenting malignancies (n=465) were breast (28%), cervical (12%), hematologic (8%), and colorectal (7%). For staged patients (n=352), the most common presentations were stage III (28%) and IV (40%). For time-to-care, patients with available data (n=208) were seen for an initial oncology clinic visit a median of 180 days (IQR 87-382) after self-reported symptom development. For time-to-chemo at any site (ex. Belize, Mexico, Guatemala), the median was 189 days (IQR 108-404). For upfront surgery at any site the median was 188 days (IQR 60-352). In contrast to these long lead times, once established at the KHMH clinic, the time from the initial oncology clinic visit to a biopsy (if not done previously) was 22 days (IQR 11-47, n=42), 18 days (IQR 5-60, n=115) to begin chemo, and 40 days (IQR 24-72, n=22) to surgery. Conclusion: Patients were seen at the KHMH oncology clinic with predominantly late stage disease around six months after symptoms started. This is a higher fraction of stage III/IV disease than previously reported in Central America. Understanding drivers of these delays will allow for the creation of targeted public health interventions. As a marker that building infrastructure in Belize is possible, the partnership between the Belizean government and hospital administration has netted time-to-care intervals comparable to high-income nations.
