PURPOSE: The Accelerated Diagnostic Assessment Program (ADAP) manages patients with imaging abnormalities, with or without concomitant symptoms, where cancer is suspected. The ADAP is offered to primary care practitioners and emergency departments with cases triaged by a medical oncologist.

METHODS: We performed a retrospective patient chart review of electronic medical records from January 2019 until June 2021 to validate the program. We collected information on the referral pathways, patient demographics, wait-times, and diagnostic results. The control group consisted of outpatients who were referred for biopsy over a 1-year period outside the ADAP stream. Statistical analyses were performed using IBM SPSS software.

RESULTS: Of the 97 patients included, 54% were female, with ages ranging from 18 to 96 years. Twenty-nine percent (n = 20) of the malignant cases were incidental findings. Most patients referred to the ADAP were diagnosed with a malignancy (71%; n = 69), comprising hematologic (45%; n = 31), GI (26%; n = 18), or other cancers (29%; n = 20). The ADAP had decreased wait-times from referral to biopsy collection (17.6 days ± 10.7 [standard deviation (SD)]; n = 43) when compared with the control group (41.2 days ± 40.0 [SD]; n = 67; P < .001). ADAP patients with malignancies saw a treating specialist 7.6 ± 7.6 days [SD] after their follow-up appointment at the ADAP.

CONCLUSION: The ADAP accelerated time to biopsy in a statistically significant manner when compared with age-, referring physician-, and biopsy site-matched controls. It also outperformed national and provincial standards, suggesting that its model addresses a gap in care by providing an underserved population timely access to diagnosis and treatment.
