e18036 Background: Cancer frequently occurs with other chronic diseases, and this poses serious care coordination challenges during patients’ active cancer treatment (ACT). There is limited research addressing chronic comorbidity (CC) management during ACT. This study aimed to examine practicing oncologists’ perceived confidence in independently managing CC during ACT. Methods: Oncologists in the National Cancer Institute’s Community Oncology Research Program (NCORP) were surveyed about their perceived confidence in managing CC. The Likert scale survey was piloted-tested, IRB-approved, and administered to oncologists. In December 2018, NCORP network oncologists were sent an email invitation to complete the online survey. Pearson chi-square test was used to identify oncologists’ differences in perceived confidence in managing CC. Results: Among the 201 respondents of the ongoing survey, 48% were medical oncologists, 21.2% radiation or surgical oncologists, and 30.8% were of other specialties. Overall, 69% agreed (agree or strongly agree), 17.3% were neutral, and 13.4% disagreed (strongly disagree or disagree) that they were confident in managing all CC independently. While 69% of oncologists were confident when managing any CC, only 49% and 19.8% remained confident when managing CC previously managed by a primary care physician (PCP) and by a non-oncology subspecialist, respectively. Across oncologic subspecialties, 47.6%, 77.9% and 72.1% of radiation/surgical oncologists, medical oncologists, and those of other specialties, respectively, agreed that they were confident in independently managing CC (p = 0.003). Conclusions: Most oncologists are confident in managing all CC during patients’ ACT. However, they were less confident with CC previously managed by PCPs, and even less confident for CC previously managed by non-oncology subspecialists. These results indicate opportunities for greater collaboration between oncology and non-oncology specialists to ensure complete and coordinated care for cancer patients with comorbidities.
