Participant Flow
12 primary care clinics (units) were randomized to use one of two engagement strategies. Patients who had an appointment at a clinic randomized to the POC arm were approached using the POC strategy (described below). Patients seen at a DPE clinic were approached using the DPE strategy. Recruitment began in September of 2020 and ended in February of 2023.
As randomization was done by clinic, 115,484 individuals started the study (115,319 patients; 165 primary care providers). The 95,623 patients seen during the 12 month window set by the study protocol serve as the denominator for the main outcomes (proportion of patients who completed the cancer risk assessment screening; proportion of patients who completed genetic testing). 20,184 individuals were officially enrolled through completing surveys or the cancer risk assessment screening.

Point of Care
Clinics in the point of care (POC) arm approached patients at the time they came in to the clinic for a routine visit with their primary care provider. The familial cancer risk screening was completed using electronic tablets in the waiting room or, in the case of a telehealth visit, through telephone contact before the visit. Patients identified as likely to benefit based on their risk profile, were offered genetic testing for a panel of hereditary cancers.
|
Direct Patient Engagement
Clinics in the direct patient engagement (DPE) arm contacted patients by postal mail and email to provide a link to the online familial cancer risk screening tool. This occurred one to three months after the patient had a routine visit with their primary care provider. Patients identified as likely to benefit based on their risk profile, were offered genetic testing for a panel of hereditary cancers.

SECONDARY outcome
Timeframe: 2 yearsPopulation: Data from only one of the participating healthcare systems were used. There were 3 clinics in the POC arm and 3 clinics in the DPE arm. Costs were calculated at the per-patient level and scaled to apply to a theoretical healthcare system with 100,000 patients.
This outcome is the total costs for each engagement strategy, scaled to a healthcare system of 100,000 patients. The total costs from the health-system perspective is the sum of program costs and staff costs over 2 years, in U.S. dollars. The cost from the limited societal perspective includes patient costs in addition to health-system costs. The total costs will be used in the incremental cost calculation below.

SECONDARY outcome
Timeframe: 2 yearsPopulation: Costs and outcomes were compared between the two arms, with POC as the comparator (standard); that is DPE minus POC. Costs were calculated at the per-patient level and scaled to apply to a theoretical healthcare system with 100,000 patients. As this outcome is the difference between the two strategies, only one value is calculated using the data from the two arms combined. The total costs per arm used for this calculation are shown in outcome 3 above.
This outcome is the comparative (incremental) cost of two different engagement strategies for population-based risk assessment for hereditary cancer genetic screening and testing in primary care. The total costs for each arm are presented in outcome 3 above. The incremental cost is the difference in total costs when comparing the DPE arm to the POC arm (DPE minus POC).

SECONDARY outcome
Timeframe: 2 yearsPopulation: Data from only one of the participating healthcare systems were used. There were 3 clinics in the POC arm and 3 clinics in the DPE arm. The percentages (i.e. proportions) in the table are based on study participant counts. These proportions will be scaled to a healthcare system of 100,000 patients when calculating the incremental differences for Outcome 6.
The table displays the percentages (i.e., proportions) of screening and testing that occurred in the study. The number of patients screened and the number tested are listed as well, but as the denominators differ, the results for Outcome 6 will be based on scaling the proportions to a theoretical healthcare system with 100,000 patients. This information will then be used along with the incremental costs for a healthcare system with 100,000 patients (Outcome 4) to determine the incremental cost-effectiveness ratios (ICERs) presented in Outcome 7.

SECONDARY outcome
Timeframe: 2 yearsPopulation: NOTE: percentages (i.e., proportions) shown in Outcome 5 were scaled to a healthcare system of 100,000 patients before calculating these incremental differences. Outcomes were then compared between the two arms (DPE minus POC). As this outcome is the difference between the two strategies, only one value is calculated using the data from the two arms combined. Again, differences were calculated after scaling the proportions, rather than simply using the participant counts from Outcome 5.
This outcome is the comparative (incremental) difference between the two different engagement strategies in screening and testing outcomes. The total patients screened and tested for each arm are presented in outcome 5 above. The proportions for these outcomes were then scaled to a healthcare system of 100,000 patients and the incremental difference was calculated by comparing the DPE arm to the POC arm (DPE minus POC). Scaling the numbers to a healthcare system of 100,000 patients is necessary for this component to be compatible with the costs for a healthcare system of 100,000 patients given in Outcome 4, in order to calculate the ICERs (Outcome 7).

SECONDARY outcome
Timeframe: 2 yearsPopulation: Costs and outcomes were compared between the two arms, with POC as the comparator (standard); in other words DPE minus POC. This combination of the two arms was the prespecified analysis. Cost effectiveness was calculated at the per-patient level, then scaled to apply to a theoretical healthcare system with 100,000 patients.
This outcome is the Incremental Cost-effectiveness Ratio (ICER). The ICER estimates how much the DPE strategy costs, relative to the POC strategy (DPE minus POC), to improve the outcome measure by 1 unit (in this case one additional patient screened or one additional patient tested). The ICER is calculated by using the difference in costs (outcome 4) divided by the difference in outcome (outcome 6). When the numerator is positive and the denominator is negative (as it is for screening), general practice is to state the second strategy (DPE in this case) was "dominated" by the first strategy (the standard, which is POC in this case). A negative ICER can be misinterpreted, making this clarification necessary.
