Team complexity and care coordination for cancer survivors with multiple chronic conditions: a mixed methods study

Little is known about the perceptions and experiences of care received from healthcare teams among cancer survivors with multiple chronic conditions (MCCs).

Cancer survivors completed an online survey (N=441) of which 12 participated in an interview. Team complexity was operationalized based on team size, clinician specialties, and health system affiliation. Kilpatrick's Patient-Perceptions of Team Effectiveness (PTE) questionnaire measured team effectiveness. Constant comparative method was used to identify care coordination challenges and facilitators from interviews.

Mean age at cancer diagnosis was 45 years (SD=14), 68% were 5 years from diagnosis, the most common cancer was breast (27%), and two-thirds had two or more pre-diagnosis comorbidities. Sixty percent rated both cancer and other condition(s) as taking priority. Team complexity varied from low (32%), moderate (49%), and high (20%). Eighty percent rated PTE overall as high, with variation by subscales: coordination (85%) and patient-family focus (47%). Higher team complexity was associated with lower PTE overall (p=0.049). Challenges were identified: sequential referrals with no integration across team members; no shared mental model among team; and cancer survivor having to "referee" conflicting care decisions.

This mixed method study found an inverse relationship between team complexity and PTE-overall, where high-complexity teams had lower team effectiveness. Participants reported issues with the problem-solving abilities of their teams and felt like their contributions were not valued by their care team.

Improving team effectiveness offers one way to leverage the expertise of multiple specialties to deliver integrated, patient-centered care for the growing population of cancer survivors with MCC.
