An observational study of workflows to support fecal testing for colorectal cancer screening in primary care practices serving Medicaid enrollees

Cancer Screening: Patient and Population Strategies

Although cancer has been the second leading cause of death for close to 100 years, progress has been made in reducing cancer mortality and morbidity, with the adoption of high-quality screening tests and treatment advances delivered at earlier stages of diagnosis. To achieve the high cancer screening rates demonstrated by some practices, proven effective strategies need to be broadly adopted at both the patient and population levels. Factors affecting cancer screening test completion and approaches to improvement are described both generally and for breast, lung, cervical, colorectal, and prostate cancers. Closing the racial disparity gap is a critical component of reaching cancer screening and prevention goals.

Data Challenges in Identifying Patients Due for Colorectal Cancer Screening in Rural Clinics

INTRODUCTION

Colorectal cancer (CRC) incidence and mortality are disproportionately high among rural residents despite the availability of effective screening methods. Outreach activities can improve CRC screening rates but rely on accurate identification of patients due for screening. We report on data challenges in rural clinics and Medicaid health plans in Oregon in identifying patients eligible for CRC screening, in a large project implementing mailed fecal immunochemical tests (FIT) and patient navigation.

METHODS

We analyzed data from clinic intake surveys and administrative claims. Clinics were asked to identify total population numbers relevant to CRC screening and follow-up. Health plans also identified enrollees eligible for CRC screening in Spring, 2021. Clinic staff validated patient lists for eligibility using their electronic health records (EHR).

RESULTS

EHR features varied across the 29 participating and 28 responding clinics. Among the 28 responding clinics, 21 were able to report their Medicaid population (75%), 19 reported the number of patients aged 50 to 75 (68%) and the number screened for CRC in the last year (68%). Only 8 (29%) were able to report screening details such as number screened by FIT and 9 were able to report on patients with an abnormal FIT or colonoscopy completed after FIT (32%). Health plans had challenges properly identifying where enrollees received care and had missing data for race and ethnicity (range 22 to 34% unknown race, <1% to 24% unknown ethnicity).

DISCUSSION

Most participating rural primary care clinics and Medicaid health plans experienced challenges identifying the population due for a CRC screening outreach program. Better EHR functionality and data reporting capabilities could help rural clinics apply population-based strategies and ultimately attenuate disparities in cancer screening and follow-up.

Improving colorectal cancer screening in rural primary care: Preliminary effectiveness and implementation of a collaborative mailed fecal immunochemical test pilot

BACKGROUND

Mailed fecal immunochemical test (FIT) outreach can improve colorectal cancer (CRC) screening rates. We piloted a collaborative mailed FIT program with health plans and rural clinics to evaluate preliminary effectiveness and refine implementation strategies.

METHODS

We conducted a single-arm study using a convergent, parallel mixed-methods design to evaluate the implementation of a collaborative mailed FIT program. Enrollees were identified using health plan claims and confirmed via clinic scrub. The intervention included a vendor-delivered automated phone call (auto-call) prompt, FIT mailing, and reminder auto-call; clinics were encouraged to make live reminder calls. Practice facilitation was the primary implementation strategy. At 12 months post mailing, we assessed the rates of: (1) mailed FIT return and (2) completion of any CRC screening. We took fieldnotes and conducted postintervention key informant interviews to assess implementation outcomes (eg, feasibility, acceptability, and adaptations).

RESULTS

One hundred and sixty-nine Medicaid or Medicare enrollees were mailed a FIT. Over the 12-month intervention, 62 participants (37%) completed screening of which 21% completed the mailed FIT (most were returned within 3 months), and 15% screened by other methods (FITs distributed in-clinic, colonoscopy). Enrollee demographics and the reminder call may encourage mailed FIT completion. Program feasibility and acceptability was high and supported by perceived positive benefit, alignment with existing workflows, adequate staffing, and practice facilitation.

CONCLUSION

Collaborative health plan-clinic mailed FIT programs are feasible and acceptable for implementation in rural clinics and support CRC screening completion. Studies that pragmatically test collaborative approaches to mailed FIT and patient navigation follow-up after abnormal FIT and support broad scale-up in rural settings are needed.

The COMPASS study: A prospective, randomized, multi-center trial testing the impact of a clinic-based intervention informing patients of colorectal cancer screening options on screening completion

Background:

Colorectal cancer (CRC) screening is underutilized despite evidence that screening improves survival. Since healthcare provider recommendation is a strong predictor of CRC screening completion, providers are encouraged to engage eligible patients in collaborative decision-making that attends to patients’ values, needs, and preferences for guideline-concordant screening modalities.

Methods:

This three-arm randomized controlled trial is testing the effectiveness of an evidence-based video intervention informing patients of screening choices delivered in a clinic prior to a healthcare appointment. We hypothesize that participants randomized to watch a basic video describing CRC and screening in addition to an informed choice video showing the advantages and disadvantages of fecal immunochemical test (FIT), stool DNA FIT (s-DNA FIT), and colonoscopy (Arm 3) will exhibit a greater proportion of time adherent to CRC screening guidelines after 1, 3 and 6 years than those who only watch the basic video (Arm 2) or no video at all (Arm 1). Primary care and Obstetrician/Gynecology clinics across the United States are recruiting 5280 patients, half who have never been screened and half who previously screened but are currently not guideline adherent. Participants complete surveys prior to and following an index appointment to self-report personal, cognitive, and environmental factors potentially associated with screening. Proportion of time adherent to screening guidelines will be assessed using medical record data and supplemented with annual surveys self-reporting screening.

Conclusion:

Results will provide evidence on the effectiveness of informational and motivational videos to encourage CRC screening that can be easily integrated into clinical practice.

Clinic Factors Associated With Mailed Fecal Immunochemical Test (FIT) Completion: The Difference-Making Role of Support Staff

PURPOSE

Mailed fecal immunochemical test (FIT) programs can facilitate colorectal cancer (CRC) screening. We sought to identify modifiable, clinic-level factors that distinguish primary care clinics with higher vs lower FIT completion rates in response to a centralized mailed FIT program.

METHODS

We used baseline observational data from 15 clinics within a single urban federally qualified health center participating in a pragmatic trial to optimize a mailed FIT program. Clinic-level data included interviews with leadership using a guide informed by the Consolidated Framework for Implementation Research (CFIR) and FIT completion rates. We used template analysis to identify explanatory factors and configurational comparative methods to identify specific combinations of clinic-level conditions that uniquely distinguished clinics with higher and lower FIT completion rates.

RESULTS

We interviewed 39 clinic leaders and identified 58 potential explanatory factors representing clinic workflows and the CFIR inner setting domain. Clinic-level FIT completion rates ranged from 30% to 56%. The configurational model for clinics with higher rates (≥37%) featured any 1 of the following 3 factors related to support staff: (1) adding back- or front-office staff in past 12 months, (2) having staff help patients resolve barriers to CRC screening, and (3) having staff hand out FITs/educate patients. The model for clinics with lower rates involved the combined absence of these same 3 factors.

CONCLUSIONS

Three factors related to support staff differentiated clinics with higher and lower FIT completion rates. Adding nonphysician support staff and having those staff provide enabling services might help clinics optimize mailed FIT screening programs.

Source matters: a survey of cost variation for fecal immunochemical tests in primary care

Background

Colorectal cancer (CRC) screening can improve health outcomes, but screening rates remain low across the US. Mailed fecal immunochemical tests (FIT) are an effective way to increase CRC screening rates, but is still underutilized. In particular, cost of FIT has not been explored in relation to practice characteristics, FIT selection, and screening outreach approaches.

Methods

We administered a cross-sectional survey drawing from prior validated measures to 252 primary care practices to assess characteristics and context that could affect the implementation of direct mail fecal testing programs, including the cost, source of test, and types of FIT used. We analyzed the range of costs for the tests, and identified practice and test procurement factors. We examined the distributions of practice characteristics for FIT use and costs answers using the non-parametric Wilcoxon rank-sum test. We used Pearson’s chi-squared test of association and interpreted a low p-value (e.g. < 0.05) as evidence of association between a given practice characteristic and knowing the cost of FIT or fecal occult blood test (FOBT).

Results

Among the 84 viable practice survey responses, more than 10 different types of FIT/FOBTs were in use; 76% of practices used one of the five most common FIT types. Only 40 practices (48%) provided information on FIT costs. Thirteen (32%) of these practices received the tests for free while 27 (68%) paid for their tests; median reported cost of a FIT was $3.04, with a range from $0.83 to $6.41 per test. Costs were not statistically significantly different by FIT type. However, practices who received FITs from manufacturer’s vendors were more likely to know the cost (p = 0.0002) and, if known, report a higher cost (p = 0.0002).

Conclusions

Our findings indicate that most practices without lab or health system supplied FITs are spending more to procure tests. Cost of FIT may impact the willingness of practices to distribute FITs through population outreach strategies, such as mailed FIT. Differences in the ability to obtain FIT tests in a cost-effective manner could have consequences for implementation of outreach programs that address colorectal cancer screening disparities in primary care practices.
