Utilization of a primary care-based cancer survivorship clinic: patterns and patient characteristics.

Purpose: The Johns Hopkins Primary Care for Cancer Survivors (PCCS) Clinic was established in 2015 to improve care delivery for the growing cancer survivor population. We aim to describe areas of care addressed by PCCS and factors associated with clinic utilization.

Methods: We conducted a retrospective chart review of the first 301 patients' clinic visits. We used negative binomial regression models to identify factors associated with the rate of PCCS clinic visits overall and for cancer surveillance and treatment-related effects.

Results: There were 1702 clinic visits across 301 patients during the study period (77% female, median age 61). The most common areas of care addressed were chronic medical problems (80%), preventive health care (62%), cancer surveillance (59%), treatment-related effects (50%), and new/acute problems (46%). Multivariate analyses found that age > 60 years (IRR = 1.9, 95% CI = 1.2-3.0, p = 0.007) and higher number of comorbidities (IRR = 1.2, 95% CI = 1.1 - 1.2, p < 0.001) were associated with more overall PCCS visits, while female gender was associated with fewer visits (IRR = 0.6, CI = 0.4 - 0.8, p = 0.001). Gastrointestinal cancer type, shorter length of survivorship, male gender, and higher number of comorbidities were associated with a higher rate of visits addressing both surveillance and treatment-related effects (p < 0.05).

Conclusions: The PCCS clinic addressed cancer and non-cancer related needs. Older patients and survivors with more comorbidities had significantly increased clinic utilization.

Implications for cancer survivors: As the cancer survivor population grows, increasing access to survivorship clinics based in primary care may help meet these patients' diverse oncologic and general health needs.
