Increasing uptake of evidence-based screening services though a community health worker-delivered multimodality program: study protocol for a randomized pragmatic trial.

ABSTRACT: BACKGROUND:Underserved ethnic minority populations experience significant disparities in HIV, hepatitis C virus (HCV), colorectal cancer (CRC), and cervical cancer incidence and mortality. Much of the excess burden of these diseases among underserved communities is due to lack of preventive care, including screening. Barriers to disease screening include low awareness, lack of access to care and health insurance, and cultural beliefs regarding disease prevention. Our current trial aims to examine community health worker (CHW)-delivered, home-based multi-modality screening for HIV, HCV, CRC, and cervical cancer simultaneously. DESIGN:We are conducting a randomized pragmatic trial among 900 Haitian, Hispanic, and African-American participants from diverse underserved communities in South Florida. People between the ages of 50 and 65 who have not had appropriate HIV, HCV, CRC, and cervical cancer screening per United States Preventive Services Task Force (USPSTF) recommendations are eligible for the study. Participants are recruited by CHWs and complete a structured interview to assess multilevel determinants of disease risk. Participants are then randomized to receive HIV, HCV, CRC, and cervical cancer screening via navigation to care by a CHW (Group 1) or via CHW-delivered home-based screening (Group 2). The primary outcome is completion of screening for each of these diseases within 6?months post-enrollment. DISCUSSION:Our trial is among the first to examine the effectiveness of a CHW-delivered, multimodality, home-based disease-screening approach. If found to be effective, this approach may represent a cost-effective strategy for disease screening within underserved and underscreened minority groups.

Project description:BACKGROUND:By 2015, Malawi had not achieved Millennium Development Goal 4, reducing maternal mortality by about 35% from 675 to 439 deaths per 100,000 livebirths. Hypothesised reasons included low uptake of antenatal care (ANC), intrapartum care, and postnatal care. Involving community health workers (CHWs) in identification of pregnant women and linking them to perinatal services is a key strategy to reinforce uptake of perinatal care in Neno, Malawi. We evaluated changes in uptake after deployment of CHWs between March 2014 and June 2016. METHODS:A CHW intervention was implemented in Neno District, Malawi in a designated catchment area of about 3100 women of childbearing age. The pre-intervention period was March 2014 to February 2015, and the post-intervention period was March 2015 to June 2016. A 5-day maternal health training package was delivered to 211 paid and supervised CHWs. CHWs were deployed to identify pregnant women and escort them to perinatal care visits. A synthetic control method, in which a "counterfactual site" was created from six available control facilities in Neno District, was used to evaluate the intervention. Outcomes of interest included uptake of first-time ANC, ANC within the first trimester, four or more ANC visits, intrapartum care, and postnatal care follow-up. RESULTS:Women enrolled in ANC increased by 18% (95% Credible Interval (CrI): 8, 29%) from an average of 83 to 98 per month, the proportion of pregnant women starting ANC in the first trimester increased by 200% (95% CrI: 162, 234%) from 10 to 29% per month, the proportion of women completing four or more ANC visits increased by 37% (95% CrI: 31, 43%) from 28 to 39%, and monthly utilisation of intrapartum care increased by 20% (95% CrI: 13, 28%) from 85 to 102 women per month. There was little evidence that the CHW intervention changed utilisation of postnatal care (- 37, 95% CrI: - 224, 170%). CONCLUSIONS:In a rural district in Malawi, uptake of ANC and intrapartum care increased considerably following an intervention using CHWs to identify pregnant women and link them to care.

Project description:Bowel cancer is the second biggest cancer killer in the UK, accounting for over 16,000 deaths per year. Screening can reduce deaths from bowel cancer if the people invited participate. The challenge is that high uptake of bowel screening is hard to achieve, and remains persistently below 65%. The faecal immunochemical test (FIT) is the most widely used bowel screening test worldwide. In the UK, FIT kits are mailed to people’s homes without guidance on when the kit should be returned and only brief instruction on how to use it. Some people have said that even though they intend to complete and return the kit, they often forget or put off doing it. Two approaches are proposed to addressing this issue: i) providing a suggested deadline for FIT return, because it is known from breast and cervical cancer screening that giving people an appointment time increases uptake compared to an open invitation, and ii) planning sheets, that have been found to help people act on their intentions in other health contexts. This trial aims to evaluate the impact of providing a suggested deadline and a planning sheet on the return of FIT bowel screening kits. The trial is integrated within the Scottish Bowel Screening Programme. The investigators will randomly allocate 40,000 consecutive people that are due to be sent a FIT kit to one of eight groups: (i) control group (no deadline, no planning sheet), (ii) intervention group (1-week deadline, no planning sheet), (iii) intervention group (2-week deadline, no planning sheet), (iv) intervention group (4-week deadline, no planning sheet), (v) intervention group (no deadline, with planning sheet), (vi) intervention group (1-week deadline, with planning sheet), (vii) intervention group (2-week deadline, with planning sheet), (viii) intervention group (4-week deadline, with planning sheet). It will then be examined if having a suggested deadline and a planning sheet affects how many people send back their completed FIT kit. It will also be examined if the deadline length makes a difference and whether having both a deadline and a planning sheet affects the number of people returning their kit. Finally, the cognitive and behavioural mechanisms underlying any intervention effects will be assessed and the acceptability of the interventions explored, using questionnaires and in-depth interviews.

Project description:BackgroundHepatitis C (HCV) is the most common infectious disease among people who inject drugs (PWID). Engaging PWID in harm reduction services, such as syringe service programs (SSPs), is critical to reduce HCV and HIV transmission. Additionally, testing for HIV and HCV among PWID is important to improve diagnosis and linkage to care. On March 1, 2018, Florida's only legal SSP implemented bundled opt-out HIV/HCV testing at enrollment. We aimed to examine the differences in HIV/HCV testing uptake before and after the implementation of the opt-out testing policy.MethodsMultivariable logistic regression was used to assess predictors of accepting HIV/HCV tests, controlling for opt-in and opt-out policy. Monthly estimates of the percent of participants accepting an HIV test, HCV test, or both were generated. Interrupted Time Series (ITS) analysis evaluated the immediate policy impact on level of uptake and trend in uptake over time for bundled HIV/HCV testing before and after the opt-out testing policy.ResultsThe total study period was 37 months between December 2016-January 2020 with 512 SSP participants 15 months prior and 547 SSP participants 22 months after implementation of bundled HIV/HCV opt-out testing. Significant predictors of accepting both HIV/HCV tests were cocaine injection (aOR = 2.36), self-reported HIV positive status (aOR = 0.39) and self-reported HCV positive status (aOR = 0.27). Based on the ITS results, there was a significant increase in uptake of HIV/HCV testing by 42.4% (95% CI: 26.2%-58.5%, p < 0.001) immediately after the policy change to opt-out testing.ConclusionBundled opt-out HIV/HCV testing substantially increased the percentage of SSP clients who received HIV and HCV rapid tests at enrollment into the program, and the effect remained stable across the 22 months post opt-out testing policy. Future investigation must assess PWID-level perspective of testing preferences and examine whether this testing approach improves HIV/HCV detection among PWID previously unaware of their status.

Project description:ImportanceIron deficiency anemia, the largest cause of anemia worldwide, adversely affects cognitive development in children. Moreover, the imperceptible childhood anemia prevalence reduction in response to anemia control measures is associated with tremendous social and economic cost.ObjectiveTo evaluate the effects of community-based parental education/counseling when combined with usual treatment on children's anemia cure rate.Design, setting, and participantsA pragmatic cluster randomized clinical trial in children aged 12 to 59 months from 55 villages from the rural Chamrajnagar district in southern India was conducted between November 2014 and July 2015; 6-month follow-up ended in January 2016. Villages were randomly assigned to either usual treatment (n = 27) or to the intervention (n = 28). Among 1144 participating children, 534 were diagnosed as having anemia (hemoglobin levels <11 g/dL and >7.9 g/dL; to convert to grams per liter, multiply by 10) and constituted the study sample in this analysis. Data were analyzed between July 2016 and September 2017.InterventionsIron and folic acid (IFA), 20 mg/d, 5 times daily per week, for 5 months (usual treatment) or health worker-delivered education/counseling combined with usual treatment (intervention).Main outcomes and measuresThe primary outcome was anemia cure rate defined as hemoglobin level at or greater than 11 g/dL during follow-up.ResultsOf the children included in the study, the mean age was 30 months, with a slightly higher ratio of boys to girls. Of 534 children with anemia (intervention n = 303; usual treatment n = 231), 517 were reassessed after 6 months (intervention n = 298; usual treatment n = 219) while 17 were lost to follow-up (intervention n = 5 and usual treatment n = 12). Anemia cure rate was higher in children in the intervention group compared with children receiving usual treatment (55.7% [n = 166 of 298] vs 41.4% [n = 90 of 219]). The risk ratio derived through multilevel logistic regression was 1.37 (95% CI, 1.04-1.70); the model-estimated risk difference was 15.1% (95% CI, 3.9-26.3). Intervention-group children demonstrated larger mean hemoglobin increments (difference, intervention vs control: 0.25 g/dL; 95% CI, 0.07-0.44 g/dL) and improved IFA adherence (61.7%; 95% CI, 56.2-67.3 vs 48.4%; 95% CI, 41.7-55.1 consumed >75% of tablets provided). Adverse events were mild (intervention: 26.8%; 95% CI, 21.8-31.9 vs usual treatment: 21%; 95% CI, 15.6-26.4). To cure 1 child with anemia, 7 mothers needed to be counseled (number needed to treat: 7; 95% CI, 4-26).Conclusions and relevanceParental education and counseling by a community health worker achieved perceivable gains in curing childhood anemia. Policy makers should consider this approach to enhance population level anemia control.Trial registrationISRCTN identifier: ISRCTN68413407.

Project description:OBJECTIVE:Compare the effectiveness of community-based HPV-related education and onsite school-based vaccination versus community-based education only for increasing HPV vaccine uptake in a rural, medically underserved area. METHODS:Our cohort included 2307 Rio Grande City Consolidated Independent School District (RGCISD) middle school students from 3 schools enrolled in August 2016 and followed until April 2018. Using a quasi-experimental design, this study implemented an onsite school-based vaccination program and physician-led education on HPV and HPV vaccines for parents/guardians, school nurses/staff, and pediatric/family providers in the surrounding community (15-mile radius of RGCCISD) at 1 middle school ("intervention school"), and education-only for the remaining 2 schools ("comparison schools"). The Centers for Disease Control and Prevention's HPV-related educational materials supplemented the education. HPV vaccine status was obtained from school immunization records and the project's contracted vaccine vendor. HPV vaccine initiation and completion rates were compared pre and post intervention and between the intervention and comparison schools. Logistic regression was used to compare the odds of newly initiating/completing vaccination between the intervention and comparison schools. RESULTS:At baseline, the intervention school had lower HPV vaccine initiation and completion rates than the comparison schools (20.00% and 8.70% vs 28.97% and 14.56%). Post intervention, the intervention school had higher initiation and completion rates than the comparison schools (53.67% and 28.36% vs 41.56% and 20.53%). Students from the intervention school were over 3.6-times more likely to newly initiate/complete the HPV vaccinations than students from the comparison schools. CONCLUSION:The school with on-site vaccination events and community-based education had a higher adolescent HPV vaccination rate compared to schools that received community-based education only.
