AIM: Financial incentives improve response to electronic health surveys, yet little is known about how unconditional incentives (guaranteed regardless of survey completion), conditional incentives, and various combinations of incentives influence response rates. We compared electronic health survey completion with two different financial incentive structures. METHODS: We invited women aged 30-64 years enrolled in a U.S. healthcare system and overdue for Pap screening to complete a web-based survey after receiving a mailed human papillomavirus (HPV) self-sampling kit in a pragmatic trial. HPV kit returners (n = 272) and non-returners (n = 1,083) were allocated to one of two different incentive structures: (1) Unconditional: $5 pre-incentive only (n = 653); (2) Combined: $2 pre-incentive plus $10 post-incentive conditional on completion (n = 702). Chi-square tests evaluated whether survey completion differed by incentive structure within kit return groups or was modified by kit return status. For each incentive-by-kit status group, the cost-per-survey response was calculated as: ([number invited*pre-incentive amount] + [number responses*post-incentive amount]) / number responses. RESULTS: Overall, survey response was higher in kit returners vs. kit non-returners (42.6% vs. 11.0%, P < 0.01), and survey response was higher in the combined (20.1%) vs. unconditional (14.4%) incentive group (P = 0.01). Kit return status did not modify the association between incentive type and survey response (P = 0.52). Among respondents, time to survey completion did not differ by incentive type among either kit returners or non-returners. Among returners, the cost-per-survey response was similar between groups ($13.57 unconditional; $14.15 combined); among non-returners, the cost was greater in the unconditional ($57.78) versus the combined ($25.22) group. CONCLUSION: A combined incentive can be cost-effective for increasing survey response in health services research, particularly in hard-to-reach populations.

BACKGROUND: The effectiveness of colorectal cancer (CRC) screening is limited by underuse, particularly among underserved populations. Among a racially diverse and socioeconomically disadvantaged cohort of patients, the authors compared the effectiveness of fecal immunochemical test (FIT) outreach and colonoscopy outreach to increase screening participation rates, compared with usual visit-based care. METHODS: Patients aged 50 to 64 years who were not up-to-date with CRC screening but used primary care services in a large safety-net health system were randomly assigned to mailed FIT outreach (2400 patients), mailed colonoscopy outreach (2400 patients), or usual care with opportunistic visit-based screening (1199 patients). Patients who did not respond to outreach invitations within 2 weeks received follow-up telephone reminders. The primary outcome was CRC screening completion within 12 months after randomization. RESULTS: Baseline patient characteristics across the 3 groups were similar. Using intention-to-screen analysis, screening participation rates were higher for FIT outreach (58.8%) and colonoscopy outreach (42.4%) than usual care (29.6%) (P <.001 for both). Screening participation with FIT outreach was higher than that for colonoscopy outreach (P <.001). Among responders, FIT outreach had a higher percentage of patients who responded before reminders (59.0% vs 29.7%; P <.001). Nearly one-half of patients in the colonoscopy outreach group crossed over to complete FIT via usual care, whereas <5% of patients in the FIT outreach group underwent usual-care colonoscopy. CONCLUSIONS: Mailed outreach invitations appear to significantly increase CRC screening rates among underserved populations. In the current study, FIT-based outreach was found to be more effective than colonoscopy-based outreach to increase 1-time screening participation. Studies with longer follow-up are needed to compare the effectiveness of outreach strategies for promoting completion of the entire screening process.

Objectives

To evaluate experiences and reactions after receiving a mailed, unsolicited human papillomavirus self-sampling kit and identify psychosocial correlates of using kits.

Methods

Survey participants were underscreened women aged 30-64 who were mailed human papillomavirus kits as part of a pragmatic trial at Kaiser Permanente Washington, a United States integrated health care system. Six months after the mailing, we invited kit returners and non-returners to complete a web survey that measured psychosocial factors (e.g. cervical cancer/human papillomavirus knowledge, attitudes toward screening), experiences, and reactions to kits. We compared responses between kit returners and non-returners.

Results

Comparing 116 kit returners (272 invited) and 119 non-returners (1083 invited), we found no clinically significant differences in psychosocial factors. Overall, survey respondents showed knowledge gaps in human papillomavirus natural history (82% did not know human papillomavirus infection can clear on its own) and interpreting human papillomavirus test results (37% did not know a human papillomavirus-negative result indicates low cancer risk). Kit returners found kits convenient and easy to use (>90%). The most common reason for non-return was low confidence in ability to correctly use a kit, although many non-returners (49%) indicated that they would consider future use. Women reported low trust in human papillomavirus testing to identify women at high risk for cervical cancer (52% in returners, 42% in non-returners).

Conclusions

Screening programs could improve uptake and acceptability of human papillomavirus self-sampling through outreach materials that emphasize the high efficacy of human papillomavirus testing for cervical cancer screening and educate patients about how to interpret results.

Women who delay or do not attend Papanicolaou (Pap) screening are at increased risk for cervical cancer. Trials in countries with organized screening programs have demonstrated that mailing high-risk (hr) human papillomavirus (HPV) self-sampling kits to under-screened women increases participation, but U.S. data are lacking. HOME is a pragmatic randomized controlled trial set within a U.S. integrated healthcare delivery system to compare two programmatic approaches for increasing cervical cancer screening uptake and effectiveness in under-screened women (>3.4years since last Pap) aged 30-64years: 1) usual care (annual patient reminders and ad hoc outreach by clinics) and 2) usual care plus mailed hrHPV self-screening kits. Over 2.5years, eligible women were identified through electronic medical record (EMR) data and randomized 1:1 to the intervention or control arm. Women in the intervention arm were mailed kits with pre-paid envelopes to return samples to the central clinical laboratory for hrHPV testing. Results were documented in the EMR to notify women's primary care providers of appropriate follow-up. Primary outcomes are detection and treatment of cervical neoplasia. Secondary outcomes are cervical cancer screening uptake, abnormal screening results, and women's experiences and attitudes towards hrHPV self-sampling and follow-up of hrHPV-positive results (measured through surveys and interviews). The trial was designed to evaluate whether a programmatic strategy incorporating hrHPV self-sampling is effective in promoting adherence to the complete screening process (including follow-up of abnormal screening results and treatment). The objective of this report is to describe the rationale and design of this pragmatic trial.

IMPORTANCE: Mailed fecal immunochemical test (FIT) outreach is more effective than colonoscopy outreach for increasing 1-time colorectal cancer (CRC) screening, but long-term effectiveness may need repeat testing and timely follow-up for abnormal results. OBJECTIVE: Compare the effectiveness of FIT outreach and colonoscopy outreach to increase completion of the CRC screening process (screening initiation and follow-up) within 3 years. DESIGN, SETTING, AND PARTICIPANTS: Pragmatic randomized clinical trial from March 2013 to July 2016 among 5999 participants aged 50 to 64 years who were receiving primary care in Parkland Health and Hospital System and were not up to date with CRC screenings. INTERVENTIONS: Random assignment to mailed FIT outreach (n = 2400), mailed colonoscopy outreach (n = 2400), or usual care with clinic-based screening (n = 1199). Outreach included processes to promote repeat annual testing for individuals in the FIT outreach group with normal results and completion of diagnostic and screening colonoscopy for those with an abnormal FIT result or assigned to colonoscopy outreach. MAIN OUTCOMES AND MEASURES: Primary outcome was screening process completion, defined as adherence to colonoscopy completion, annual testing for a normal FIT result, diagnostic colonoscopy for an abnormal FIT result, or treatment evaluation if CRC was detected. Secondary outcomes included detection of any adenoma or advanced neoplasia (including CRC) and screening-related harms (including bleeding or perforation). RESULTS: All 5999 participants (median age, 56 years; women, 61.9%) were included in the intention-to-screen analyses. Screening process completion was 38.4% in the colonoscopy outreach group, 28.0% in the FIT outreach group, and 10.7% in the usual care group. Compared with the usual care group, between-group differences for completion were higher for both outreach groups (27.7% [95% CI, 25.1% to 30.4%] for the colonoscopy outreach group; 17.3% [95% CI, 14.8% to 19.8%] for FIT outreach group), and highest in the colonoscopy outreach group (10.4% [95% CI, 7.8% to 13.1%] for the colonoscopy outreach group vs FIT outreach group; P < .001 for all comparisons). Compared with usual care, the between-group differences in adenoma and advanced neoplasia detection rates were higher for both outreach groups (colonoscopy outreach group: 10.3% [95% CI, 9.5% to 12.1%] for adenoma and 3.1% [95% CI, 2.0% to 4.1%] for advanced neoplasia, P < .001 for both comparisons; FIT outreach group: 1.3% [95% CI, -0.1% to 2.8%] for adenoma and 0.7% [95% CI, -0.2% to 1.6%] for advanced neoplasia, P < .08 and P < .13, respectively), and highest in the colonoscopy outreach group (colonoscopy outreach group vs FIT outreach group: 9.0% [95% CI, 7.3% to 10.7%] for adenoma and 2.4% [95% CI, 1.3% to 3.3%] for advanced neoplasia, P < .001 for both comparisons). There were no screening-related harms in any groups. CONCLUSIONS AND RELEVANCE: Among persons aged 50 to 64 years receiving primary care at a safety-net institution, mailed outreach invitations offering FIT or colonoscopy compared with usual care increased the proportion completing CRC screening process within 3 years. The rate of screening process completion was higher with colonoscopy than FIT outreach. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01710215.

Objective

We explored patient perspectives after a positive human papillomavirus (HPV) self-sampling result to describe experiences and information needs for this home-based screening modality.

Materials and methods

We recruited women who tested high-risk (hr) HPV positive during a pragmatic trial evaluating mailed hrHPV self-sampling kits as an outreach strategy for women overdue for Pap screening in a U.S. integrated health care system. Telephone interviews were conducted from 2014 to 2017. Five independent coders analyzed transcripts using iterative content analysis.

Results

Forty-six women (61% of invited; median age 55.5 years) completed a semistructured interview. Six themes emerged: (1) convenience of home-based screening, (2) intense feelings and emotions after receiving positive kit results, (3) importance of seeing provider and discussing kit results, (4) information seeking from various sources, (5) confusion about purpose and meaning of HPV versus Pap tests, and (6) concern that HPV self-sampling is inaccurate when the subsequent Pap test is normal.

Conclusions

Although women liked the kit's convenience, discussion about discordant home HPV and in-clinic Pap results led them to question the accuracy of HPV self-sampling. Patient-provider communication around home HPV kits is more complex than for reflex or cotesting because clinician-collected Pap results are unknown at the time of the positive kit result. Patients need education about differences between HPV and Pap tests and how they are used for screening and follow-up. To reassure patients and keep them interested in self-sampling, education should be provided at multiple time points during the screening process.

Objective

Self-persuasion is an effective behavior change strategy, but has not been translated for low-income, less educated, uninsured populations attending safety-net clinics or to promote human papillomavirus (HPV) vaccination. We developed a tablet-based application (in English and Spanish) to elicit parental self-persuasion for adolescent HPV vaccination and evaluated its feasibility in a safety-net population.

Methods

Parents (N=45) of age-eligible adolescents used the self-persuasion application. Then, during cognitive interviews, staff gathered quantitative and qualitative feedback on the self-persuasion tasks including parental decision stage.

Results

The self-persuasion tasks were rated as easy to complete and helpful. We identified six question prompts rated as uniformly helpful, not difficult to answer, and generated non-redundant responses from participants. Among the 33 parents with unvaccinated adolescents, 27 (81.8%) reported deciding to get their adolescent vaccinated after completing the self-persuasion tasks.

Conclusions

The self-persuasion application was feasible and resulted in a change in parents' decision stage. Future studies can now test the efficacy of the tablet-based application on HPV vaccination.

Practice implications

The self-persuasion application facilitates verbalization of reasons for HPV vaccination in low literacy, safety-net settings. This self-administered application has the potential to be more easily incorporated into clinical practice than other patient education approaches.
