Primary care provider perspectives on the role of community pharmacy in colorectal cancer screening: a qualitative study

Colorectal cancer screening knowledge among community pharmacists: A national survey

BACKGROUND

Colorectal cancer (CRC) screening can reduce CRC morbidity and mortality. Community pharmacies could be a viable option for delivering home-based CRC screening tests such as fecal immunochemical tests (FITs). However, little is known about community pharmacists' knowledge about CRC screening guidelines.

OBJECTIVE

We assessed community pharmacists' knowledge about CRC screening to identify education and training needs for a pharmacy-based CRC screening program.

METHODS

Between September 2022 and January 2023, we conducted an online national survey of community pharmacists practicing in the United States. Responders were eligible if they were currently-licensed community pharmacists and currently practiced in the United States. The survey assessed knowledge of national CRC screening guidelines, including recommended starting age, frequency of screening, different screening modalities, and follow-up care. Using multiple linear regression, we evaluated correlates of community pharmacists' level of CRC screening knowledge, defined as the total number of knowledge questions answered correctly from "0" (no questions correct) to "5" (all questions correct).

RESULTS

A total of 578 eligible community pharmacists completed the survey, with a response rate of 59%. Most community pharmacists correctly answered the question about the next steps following a positive FIT (87%) and the question about where a FIT can be done (84%). A minority of community pharmacists responded correctly to questions about the age to start screening with FIT (34%) and how often a FIT should be repeated (28%). Only 5% of pharmacists answered all knowledge questions correctly. Community pharmacists answered more CRC screening knowledge questions correctly as their years in practice increased. Board-certified community pharmacists answered more CRC screening knowledge questions correctly compared to those who were not board-certified.

CONCLUSION

To ensure the successful implementation of a pharmacy-based CRC screening program, community pharmacists need to be educated about CRC screening and trained to ensure comprehensive patient counseling and preventive service delivery.

Patient Willingness to Use a Pharmacy-Based Colorectal Cancer Screening Service: A National Survey of U.S. Adults

BACKGROUND

We aimed to understand U.S. adults' willingness to use a pharmacy-based fecal immunochemical test (FIT) distribution service for routine colorectal cancer screening called PharmFIT using Diffusion of Innovation Theory, evaluating patient's appraisals of the program's relative advantage, compatibility, and complexity.

METHODS

From March to April 2021, we conducted a national online survey of 1,045 U.S. adults ages 45 to 75. We identified correlates of patient willingness to use PharmFIT using structural equation modeling.

RESULTS

Most respondents (72%) were willing to get a FIT from their pharmacy for their regular colorectal cancer screening. Respondents were more willing to participate in PharmFIT if they perceived higher relative advantage ($\hat{\beta}$= 0.184; confidence interval, CI95%: 0.055-0.325) and perceived higher compatibility ($\hat{\beta}$ = 0.422; CI95%: 0.253-0.599) to get screened in a pharmacy, had longer travel times to their primary health care provider ($\hat{\beta}$ = 0.007; CI95%: 0.004-0.010). Respondents were less willing to participate in PharmFIT if they were 65 years or older ($\hat{\beta}$ = -0.220; CI95%: -0.362 to -0.070).

CONCLUSIONS

Most U.S. adults would be willing to participate in PharmFIT for their routine colorectal cancer screening. Patient perceptions of the relative advantage and compatibility of PharmFIT were strongly associated with their willingness to use PharmFIT. Pharmacies should account for patient preferences for these two traits of PharmFIT to increase adoption and use.

IMPACT

Pharmacy-based colorectal cancer screening may be a viable public health strategy to significantly increase equitable access to screening for U.S. residents.

How pharmacists would design and implement a community pharmacy-based colorectal cancer screening program

Background

Distributing CRC screening through pharmacies, a highly accessible health service, may create opportunities for more equitable access to CRC screening. However, providing CRC screening in a new context introduces a substantial implementation challenge.

Methods

We conducted 23 semi-structured interviews with community pharmacists practicing in Washington state and North Carolina about distributing fecal immunochemical tests (FIT) to patients in the pharmacy. The Consolidated Framework for Implementation Research (CFIR) was used to guide analysis.

Results

Pharmacists believed that delivering FITs was highly compatible with their environment, workflow, and scope of practice. While knowledge about FIT eligibility criteria varied, pharmacists felt comfortable screening patients. They identified standardized eligibility criteria, patient-facing educational materials, and continuing education as essential design features. Pharmacists proposed adapting existing pharmacy electronic health record systems for patient reminders/prompts to facilitate FIT completion. While pharmacists felt confident that they could discuss test results with patients, they also expressed a need for stronger communication and care coordination with primary care providers.

Discussion

When designing a pharmacy-based CRC screening program, pharmacists desired programmatic procedures to fit their current knowledge and context. Findings indicate that if proper attention is given to multi-level factors, FIT delivery can be extended to pharmacies.
