Abstract
BACKGROUND: Lung cancer is often diagnosed at a late stage with high associated mortality. Timely diagnosis depends on timely referral to a respiratory specialist; however, in Canada, little is known about how patients move through primary care to get to a respiratory specialist. Accordingly, we aimed to identify and describe lung cancer pre-diagnostic pathways in primary care from first presentation to referral. METHODS: In this retrospective cohort study, patients with primary lung cancer were recruited using consecutive sampling (n = 50) from a lung cancer center in Montréal, Québec. Data on healthcare service utilization in primary care were collected from chart reviews and structured patient interviews and analyzed using latent class analysis to identify groups of patients with similar pre-diagnostic pathways. Each group was described based on patient- and tumor-related characteristics and the sequence of utilization activities. RESULTS: 68% of the patients followed a pathway where family physician (FP) visits were dominant ("FP-centric") and 32% followed a pathway where walk-in clinic and emergency department (ED) visits were dominant ("ED-centric"). Time to referral in the FP group was double that of the ED group (45 days (IQR: 12-111) vs. 22 (IQR: 5-69)) with more advanced disease (65% vs. 50%). In the FP group, 29% of the patients saw their FP three times or more before being referred and 41% had an ED visit. CONCLUSIONS: Our findings may reflect the challenge of diagnosing lung cancer in primary care, missed opportunities for earlier diagnosis, and a lack of integration between primary and specialist care.
