Evaluating Partial Series Childhood Vaccination Services in a Mobile Clinic Setting.

ABSTRACT: This study aims to evaluate the cost-benefit of vaccination services, mostly partial series administration, provided by a mobile clinic program (MCP) in Houston for children of transient and low-income families. The study included 469 patients who visited the mobile clinics on regular service days in 2 study periods in 2014 and 836 patients who attended vaccination events in the summer of 2014. The benefit of partial series vaccination was estimated based on vaccine efficacy/effectiveness data. Our conservative cost-benefit estimates show that, compared with office-based settings, every dollar spent on vaccination by the MCP would result in $0.9 societal cost averted as an incremental benefit in regular service days and $3.7 during vaccination-only events. To further improve the cost-benefit of vaccination services in the MCP, decision-makers and stakeholders may consider improving work efficiency during regular service days or hosting more vaccination events.

Project description:BackgroundVaccination services are increasingly in demand by the public, and mobile apps are an effective tool to meet that demand. However, the characteristics and quality of these apps are unknown.ObjectiveCommonly used vaccination service apps on the market were surveyed with regard to quality, service content, and user experience to evaluate and guide users.MethodsThe Qimai Data mobile app data analytics platform was used to search for common vaccination service apps by keyword, and the WeChat and Alipay platforms were searched for apps. The apps included in the study were independently evaluated by two reviewers using the Mobile Application Rating Scale, and the service content and user experience of the apps were analyzed. The intragroup correlation coefficient between raters was used to measure interrater reliability.ResultsIn the app stores of the four major Android platforms and the iOS app store, 1092 and 207 apps were found, respectively; 189 WeChat applets and 30 Alipay applets were also found. A total of 29 apps was ultimately included in this study according to the inclusion criteria, including 21 independent apps, 4 WeChat applets, and 4 Alipay applets. Significant differences were found between independent apps and applets in terms of the quality score (t449.57=-5.301; P<.001) and the subjective quality score (z=-4.753; P<.001). No significant differences were found between iOS and Android platforms in terms of the quality score (t1404=-2.55; P=.80) and the subjective quality score (z=-0.137; P=.89). There was good intragroup consistency among the raters.ConclusionsIn this study, independent apps and nonindependent apps that rely on social and payment platforms for implementation were included in the vaccination services category. The overall quality of these apps was acceptable. Nonindependent running apps were found to have slightly lower scores and showed room for improvement, and scores for the participatory apps were found to be generally low overall.

Project description:Many unhealthy dietary and physical activity habits that foster the development of obesity are established by the age of five. Presently, approximately 70 percent of children in the United States are currently enrolled in early childcare facilities, making this an ideal setting to implement and evaluate childhood obesity prevention efforts. We describe here the methods for conducting an obesity prevention randomized trial in the child care setting.A randomized, controlled obesity prevention trial is currently being conducted over a three year period (2010-present). The sample consists of 28 low-income, ethnically diverse child care centers with 1105 children (sample is 60% Hispanic, 15% Haitian, 12% Black, 2% non-Hispanic White and 71% of caregivers were born outside of the US). The purpose is to test the efficacy of a parent and teacher role-modeling intervention on children's nutrition and physical activity behaviors. . The Healthy Caregivers-Healthy Children (HC2) intervention arm schools received a combination of (1) implementing a daily curricula for teachers/parents (the nutritional gatekeepers); (2) implementing a daily curricula for children; (3) technical assistance with meal and snack menu modifications such as including more fresh and less canned produce; and (4) creation of a center policy for dietary requirements for meals and snacks, physical activity and screen time. Control arm schools received an attention control safety curriculum. Major outcome measures include pre-post changes in child body mass index percentile and z score, fruit and vegetable and other nutritious food intake, amount of physical activity, and parental nutrition and physical activity knowledge, attitudes, and beliefs, defined by intentions and behaviors. All measures were administered at the beginning and end of the school year for year one and year two of the study for a total of 4 longitudinal time points for assessment.Although few attempts have been made to prevent obesity during the first years of life, this period may represent the best opportunity for obesity prevention. Findings from this investigation will inform both the fields of childhood obesity prevention and early childhood research about the effects of an obesity prevention program housed in the childcare setting.NCT01722032.

Project description:ObjectiveTo evaluate the impact of mobile vaccination units on COVID-19 vaccine uptake of the first dose, the percentage of vaccinated people among the total eligible population. We further investigate whether such an effect differed by deprivation, ethnicity and age.DesignSynthetic control analysis.SettingThe population registered with general practices (GPs) in nine local authority areas in Cheshire and Merseyside in Northwest England, UK.InterventionMobile vaccination units that visited 37 sites on 54 occasions between 12 April 2021 and 28 June 2021. We defined intervention neighbourhoods as having their population weighted centroid located within 1 km of mobile vaccination sites (338 006 individuals). A weighted combination of neighbourhoods that had not received the intervention (1 495 582 individuals) was used to construct a synthetic control group.OutcomeThe weekly number of first-dose vaccines received among people aged 18 years and over as a proportion of the population.ResultsThe introduction of a mobile vaccination unit into a neighbourhood increased the number of first vaccinations conducted in the neighbourhood by 25% (95% CI 21% to 28%) within 3 weeks after the first visit to a neighbourhood, compared with the synthetic control group. Interaction analyses showed smaller or no effect among older age groups, Asian and black ethnic groups, and the most socioeconomically deprived populations.ConclusionsMobile vaccination units are effective interventions for increasing vaccination uptake, at least in the short term. While mobile units can be geographically targeted to reduce inequalities, we found evidence that they may increase inequalities in vaccine uptake within targeted areas, as the intervention was less effective among groups that tended to have lower vaccination uptake. Mobile vaccination units should be used in combination with activities to maximise outreach with black and Asian communities and socioeconomically disadvantaged groups.

Project description:IntroductionBarriers to pre-exposure prophylaxis (PrEP) access have limited its reach to priority populations. Community-based mobile clinics have potential to broaden PrEP engagement. We evaluated reach and persistence for fixed and mobile clinic cohorts in Miami-Dade County, Florida.MethodsThis observational cohort study analysed data from 1896 clients engaged through our fixed or mobile clinic from August 2018 to March 2023. Services were offered at no cost to clients. The same staff and package of barrier-lowering strategies was deployed across fixed and mobile clinic sites. Chi-square and Fisher's exact test or the Kruskal-Wallis test were used to test for differences in characteristics across sites as well as across services sought. Kaplan-Meier curves were generated to evaluate persistence on PrEP and in care, defined as completion of at least one clinic visit (including PrEP prescribing, for PrEP persistence, or for any reason, for persistence in care) within 24 weeks of the prior visit. Cox proportional hazards models were used to evaluate risk factors for discontinuation of PrEP or clinic care by 48 weeks by gender, race, ethnicity, insurance status and site.ResultsThe fixed and mobile clinics reached 781 and 1109 clients, respectively, during the study period. The median client age was 35 years; the majority (70.4%) of clients were cisgender men, identified as Hispanic/Latino (62.5%) and were men who have sex with men (54.5%). The mobile clinic extended reach to a higher proportion of cisgender women (32.1% mobile vs. 12.9% for fixed clinic), Black clients (34.5% vs. 13.1%) and older clients (median 37 vs. 33 years) compared with the fixed setting. Uninsured individuals, men and those who initiated services in the mobile clinic were more likely to continue PrEP to 48 weeks (HR: 1.20, p = 0.01; HR: 2.02, p<0.01; HR: 1.68, p<0.01, respectively). Persistence did not differ by race or ethnicity.ConclusionsA mobile clinic strategy for PrEP engagement can increase reach to key populations underrepresented in HIV prevention care including cisgender women and Black clients. Persistence in PrEP was increased for the mobile clinic cohort, suggesting an additional benefit to this modality beyond other barrier-lowering strategies employed in our fixed and mobile clinics.
