Study Arms (2)

Intervention Condition

EXPERIMENTAL

The trial will test the efficacy of an embedded primary care provider (PCP) model (experimental condition) in which PCPs are trained in survivorship and then embedded within an oncology practice to care for low-risk, early stage breast and colorectal cancer survivors who will be transitioned at 6-36 months post-treatment for comprehensive survivorship care.

Other: Embedded primary care in cancer survivorship model

Control Condition

NO INTERVENTION

Usual care for breast and colorectal cancer survivors (oncology-led model).

Interventions

Primacy care physicians will receive comprehensive training in cancer survivorship care for low-risk, early stage breast and colorectal patients. Training will include continuing medical education (CME) modules, webinars, and in-person discussion and clinical shadowing.

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients: Adult (21+) Kaiser Permanente Southern California members diagnosed and treated for pathologically confirmed first primary early-stage breast (stage 0, I, II) or colorectal (stage I, II) cancer within Kaiser Permanente Southern California. Completed active cancer treatment within the past 6-36 months; active treatment includes cancer-directed surgery, chemotherapy (includes Herceptin (Trastuzumab)), radiation therapy, and ovarian suppression therapy (e.g., Goserelin (Zoladex)). Completed at least one office visit within Kaiser Permanente Southern California medical oncology. At low-risk for cancer recurrence and treatment-related toxicities based on state of disease and treatment modalities. For our Aim 2 survey: Primary language of English or Spanish (although we will assess our Aim 1 participants for recorded preferred spoken language and adjust translations as needed). Ability to complete surveys of patient-reported outcomes.
  • Physicians: For centers assigned to the embedded primary care physician (PCP) model, PCPs selected to participate must be Board Certified in a relevant primary care specialty; hold a valid and current MD or advanced practitioner license; and be employed by the Southern California Permanente Medical Group.

You may not qualify if:

  • Patients less than 21 years of age
  • Patients at high risk for recurrence and treatment-related toxicities based on stage of disease and treatment modalities

Model Details: Embedded primary care providers (PCPs) will provide comprehensive care for survivors, including cancer surveillance services, preventive care, and management of long-term therapy and associated side effects (e.g., endocrine therapy in breast survivors). A comprehensive multilevel approach will prepare survivors and PCPs (physicians and/or advance practice providers). Eligible patients in the embedded PCP model will be provided with tailored education regarding the planned transition and, after cessation of active treatment, printed information on the planned course of care, expectations for embedded PCP care, transition timing, and reassurance that the oncology team will be available via telephone and email, and that PCPs will refer back to the oncologist for any concerning signs or symptoms. Tailored alerts will also be added to the electronic medical record (EMR) for recommended cancer surveillance and preventive care services that will fire for visits with embedded PCPs.
