Abstract The purpose of this study was to examine self-determination outcome data in the year following a one-year cluster randomized controlled trial (C-RCT) comparing the impacts of a Self-Determined Learning Model of Instruction (SDLMI) only condition to a SDLMI + Whose Future Is It? (SDLMI + WF) condition. Using multilevel B-spline model analysis with Bayesian estimation, we examined ongoing patterns of growth after the trial ended and all students were exposed to SDLMI + WF. The findings suggest that the inclusion of an additional year of outcome data provided additional insight into the impact of more intensive intervention conditions over time. Specifically, after the initial year of implementation, the SDLMI + WF condition predicted greater annual gains than the SDLMI only condition, unlike findings in the first year which reflected the opposite pattern. This evidence suggests a nonlinear growth pattern over multiple years of intervention with more intensive interventions. Implications for future research and practice are discussed.

The Impact

BACKGROUND: Successful shared decision making (SDM) in clinical practice requires that future clinicians learn to appreciate the value of patient participation as early as in their medical training. Narratives, such as patient testimonials, have been successfully used to support patients’ decision-making process. Previous research suggests that narratives may also be used for increasing clinicians’ empathy and responsiveness in medical consultations. However, so far, no studies have investigated the benefits of narratives for conveying the relevance of SDM to medical students.METHODS: In this randomized controlled experiment, N = 167 medical students were put into a scenario where they prepared for medical consultation with a patient having Parkinson disease. After receiving general information, participants read either a narrative patient testimonial or a fact-based information text. We measured their perceptions of SDM, their control preferences (i.e., their priorities as to who should make the decision), and the time they intended to spend for the consultation.RESULTS: Participants in the narrative patient testimonial condition referred more strongly to the patient as the one who should make decisions than participants who read the information text. Participants who read the patient narrative also considered SDM in situations with more than one treatment option to be more important than participants in the information text condition. There were no group differences regarding their control preferences. Participants who read the patient testimonial indicated that they would schedule more time for the consultation.CONCLUSIONS: These findings show that narratives can potentially be useful for imparting the relevance of SDM and patient-centered values to medical students. We discuss possible causes of this effect and implications for training and future research.

Abstract The STEADI Options trial uses a randomized, controlled-trial design to assess the effectiveness and cost-effectiveness of the STEADI Initiative . Beginning March, 2020, we will randomize 3,000 adults ≥ 65 years of age at risk for falls seen in an Emory Clinic primary care practice to: (1) full STEADI; (2) a STEADI-derived gait, balance, and strength assessment with physical therapy referrals; (3) a STEADI-derived medication review and management; or (4) usual care. This presentation will discuss decisions made by the study team to facilitate implementation of STEADI including electronically conducting screening prior to the date of encounter, the use of dedicated nursing staff to conduct assessments, implementation of strength, balance, orthostatic hypotension, and vision testing, methods to facilitate medication review, and communication of assessment information to providers. The results from this study will be used to estimate the impact of STEADI on falls, service utilization, and costs over one year.

Abstract Background The need to develop new products and novel approaches for malaria vector control is recognized as a global health priority. One approach to meeting this need has been the development of new products for indoor residual spraying (IRS) with novel active ingredients for public health. While initial results showing the impact of several of these next-generation IRS products have been encouraging, questions remain about how to best deploy them for maximum impact. To help address these questions, a 2-year cluster-randomized controlled trial to measure the impact of IRS with a microencapsulated formulation of pirimiphos-methyl (PM) in an area with high ownership of long-lasting insecticidal nets (LLINs) was conducted in a high-transmission district of central Mozambique with pyrethroid resistant vectors. Presented here are the results of the vector surveillance component of the trial. Methods The 2 year, two-armed trial was conducted in Mopeia District, Zambezia Province, Mozambique. In ten sentinel villages, five that received IRS with PM in October–November 2016 and again in October–November 2017 and five that received no IRS, indoor light trap collections and paired indoor-outdoor human landing collections catches (HLCs) were conducted monthly from September 2016 through October 2018. A universal coverage campaign in June 2017, just prior to the second spray round, distributed 131,540 standard alpha-cypermethrin LLINs across all study villages and increased overall net usage rates in children under 5 years old to over 90%. Results The primary malaria vector during the trial was Anopheles funestus sensu lato (s.l.), and standard World Health Organization (WHO) tube tests with this population indicated variable but increasing resistance to pyrethroids (including alpha-cypermethrin, from > 85% mortality in 2017 to 7% mortality in 2018) and uniform susceptibility to PM (100% mortality in both years). Over the entire duration of the study, IRS reduced An. funestus s.l. densities by 48% (CI95 33–59%; p < 0.001) in indoor light traps and by 74% (CI95 38–90%; p = 0.010) during indoor and outdoor HLC, though in each study year reductions in vector density were consistently greatest in those months immediately following the IRS campaigns and waned over time. Overall there was no strong preference for An. funestus to feed indoors or outdoors, and these biting behaviours did not differ significantly across study arms: observed indoor-outdoor biting ratios were 1.10 (CI95 1.00–1.21) in no-IRS villages and 0.88 (CI95 0.67–1.15) in IRS villages. The impact of IRS was consistent in reducing HLC exposures both indoors (75% reduction: CI95 47–88%; p = 0. < 0.001) and outdoors (68% reduction: CI95 22–87%; p = 0.012). While substantially fewer Anopheles gambiae s.l. were collected during the study, trends show a similar impact of IRS on this key vector group as well, with a 33% (CI95 7–53%; p = 0.019) reduction in mosquitoes collected in light traps and a non-statistically significant 39% reduction (p = 0.249) in HLC landing rates. Conclusion IRS with PM used in addition to pyrethroid-only LLINs substantially reduced human exposures to malaria vectors during both years of the cluster-randomized controlled trial in Mopeia—a high-burden district where the primary vector, An. funestus s.l., was equally likely to feed indoors or outdoors and demonstrated increasing resistance to pyrethroids. Findings suggest that IRS with PM can provide effective vector control, including in some settings where pyrethroid-only ITNs are widely used. Trial registrationclinicaltrials.gov, NCT02910934.

AbstractIn recent years, there has been a surge in research in spatial thinking across the international community. We now know that spatial skills are malleable and that they are linked to success across multiple disciplines, most notably Science, Technology, Engineering and Mathematics (STEM). While spatial skills have been examined by cognitive scientists in laboratory environments for decades, current research is examining how these skills can be developed in field-based environments. In this paper, we present findings from a study within a Technology Teacher preparation programme where we examined first-year students’ spatial skills on entry to university. We explain why it was necessary to embed a spatial skills intervention into Year 1 of the programme and we describe the impact that this had on students’ spatial scores and on academic performance. The findings from our study highlight a consistent gender gap in spatial scores at the start of the first-year with female students entering the Technology Teacher preparation programme at a lower base level than male students. We describe how we integrated spatial development activities into an existing course and how an improvement in spatial scores and overall course performance was observed. The paper concludes by discussing the long-term sustainability of integrating spatial interventions within teacher preparation programmes while also highlighting the importance of future research to examine spatial skills as a fundamental component of technological capability.

Abstract Background Despite being considered preventable, ulcers due to pressure affect between 30 and 50% of patients at high and very high risk and susceptibility, especially those hospitalized under critical care. Despite a lack of evidence over the efficacy in prevention against ulcers due to pressure, hourly repositioning in critical care as an intervention is used with more or less frequency to alleviate pressure on patients’ tissues. This brings up the objective of our study, which is to evaluate the efficacy in prevention of ulcers due to pressure acquired during hospitalization, specifically regarding two frequency levels of repositioning or manual posture switching in adults hospitalized in different intensive care units in different Colombian hospitals. Methods A nurse-applied cluster randomized controlled trial of parallel groups (two branches), in which 22 eligible ICUs (each consisting of 150 patients), will be randomized to a high-frequency level repositioning intervention or to a conventional care (control group). Patients will be followed until their exit from each cluster. The primary result of this study is originated by regarding pressure ulcers using clusters (number of first ulcers per patient, at the early stage of progression, first one acquired after admission for 1000 days). The secondary results include evaluating the risk index on the patients’ level (Hazard ratio, 95% IC) and a description of repositioning complications. Two interim analyses will be performed through the course of this study. A statistical difference between the groups < 0.05 in the main outcome, the progression of ulcers due to pressure (best or worst outcome in the experimental group), will determine whether the study should be put to a halt/determine the termination of the study. Conclusion This study is innovative in its use of clusters to advance knowledge of the impact of repositioning as a prevention strategy against the appearance of ulcers caused by pressure in critical care patients. The resulting recommendations of this study can be used for future clinical practice guidelines in prevention and safety for patients at risk.

Abstract Background There are major gaps in the management of pediatric tuberculosis (TB) contact investigation for rapid identification of active tuberculosis and initiation of preventive therapy. This study aims to evaluate the impact of a community-based intervention as compared to facility-based model for the management of children in contact with bacteriologically confirmed pulmonary TB adults in low-resource high-burden settings. Methods/design This multicenter parallel open-label cluster randomized controlled trial is composed of three phases: I, baseline phase in which retrospective data are collected, quality of data recording in facility registers is checked, and expected acceptability and feasibility of the intervention is assessed; II, intervention phase with enrolment of index cases and contact cases in either facility- or community-based models; and III, explanatory phase including endpoint data analysis, cost-effectiveness analysis, and post-intervention acceptability assessment by healthcare providers and beneficiaries. The study uses both quantitative and qualitative analysis methods. The community-based intervention includes identification and screening of all household contacts, referral of contacts with TB-suggestive symptoms to the facility for investigation, and household initiation of preventive therapy with follow-up of eligible child contacts by community healthcare workers, i.e., all young (< 5 years) child contacts or older (5–14 years) child contacts living with HIV, and with no evidence of TB disease. Twenty clusters representing TB diagnostic and treatment facilities with their catchment areas are randomized in a 1:1 ratio to either the community-based intervention arm or the facility-based standard of care arm in Cameroon and Uganda. Randomization was stratified by country and constrained on the number of index cases per cluster. The primary endpoint is the proportion of eligible child contacts who initiate and complete the preventive therapy. The sample size is of 1500 child contacts to identify a 10% difference between the arms with the assumption that 60% of children will complete the preventive therapy in the standard of care arm. Discussion This study will provide evidence of the impact of a community-based intervention on household child contact screening and management of TB preventive therapy in order to improve care and prevention of childhood TB in low-resource high-burden settings.

Background: Antenatal care (ANC) in many low- and middle-income countries is under-utilized and of sub-optimal quality. Group ANC (G-ANC) is an intervention designed to improve the experience and provision of ANC for groups of women (cohorts) at similar stages of pregnancy. Methods: A two-arm, two-phase, cluster randomized controlled trial (cRCT) (non-blinded) is being conducted in Kenya and Nigeria. Public health facilities were matched and randomized to either standard individual ANC (control) or G-ANC (intervention) prior to enrollment. Participants include pregnant women attending first ANC at gestational age <24 weeks, health care providers, and sub-national health managers. Enrollment ended in June 2017 for both countries. In the intervention arm, pregnant women are assigned to cohorts at first ANC visit and receive subsequent care together during five meetings facilitated by a health care provider (Phase 1). After birth, the same cohorts meet four times over 12 months with their babies (Phase 2). Data collection was performed through surveys, clinical data extraction, focus group discussions, and in-depth interviews. Phase 1 data collection ended in January 2018 and Phase 2 concludes in November 2018. Intention-to-treat analysis will be used to evaluate primary outcomes for Phases 1 and 2: health facility delivery and use of a modern method of family planning at 12 months postpartum, respectively. Data analysis and reporting of results will be consistent with norms for cRCTs. General estimating equation models that account for clustering will be employed for primary outcome analyzes. Results: Overall 1,075 and 1,013 pregnant women were enrolled in Nigeria and Kenya, respectively. Final study results will be available in February 2019. Conclusions: This is the first cRCT on G-ANC in Africa. It is among the first to examine the effects of continuing group care through the first year postpartum.

Abstract The In2Care® EaveTube is a house modification designed to block and kill malaria mosquitoes using an electrostatic netting treated with insecticide powder. A previous study demonstrated prolonged duration of effective action of insecticide-treated electrostatic netting in a semi-field setting. As part of a cluster randomized controlled trial (CRT) of the EaveTube intervention in Cote d’Ivoire, we investigated the residual efficacy of a pyrethroid insecticide deployed in Eave Tubes under village condition of use. We also explored the scope of using existing malaria control technologies including LLINs and IRS as alternative methods to deliver insecticides in the lethal house lure. The efficacy of beta-cyfluthrin was evaluated using the “eave tube bioassay” and was found to be relatively short-lived in the field during the CRT, with mortality of pyrethroid resistant Anopheles gambiae mosquitoes declining below 80% after 4 months. The impact (mosquito mortality) of PVC tubes coated with pirimiphos methyl was similar to that of beta-cyfluthrin treated insert (66.8 vs 62.8%) in release-recapture experiments in experimental huts. Efficacy was significantly lower with all the LLINs tested; however, the roof of PermaNet 3.0 induced significantly higher mosquito mortality (50.4%) compared to Olyset Plus (25.9%) and Interceptor G2 (21.6%) LLINs. The new delivery methods showed a rapid decline in efficacy over time with mortality decreasing below 50% within 2 months in residual activity bioassays. None of the current products appeared superior to the powder treatments but as with the powders, further research and development on formulations and doses are required.

Abstract Objectives To assess the effects of BWCs on prosecutorial and court-related charge outcomes across multiple crime types, including domestic violence charges, crimes committed against police officers, and drug/alcohol charges. Methods A cluster-randomized controlled trial with 22 spatiotemporal police units assigned to BWCs and 17 assigned to control conditions. Data from the State Attorney’s Office were used to track convictions, adjudication withheld dispositions, and declined prosecutions for both experimental and control charges. A series of multilevel logistic and negative binomial regression models were used to estimate the effect of BWC footage on charge outcomes. Outcomes BWCs led to a significantly higher proportion of crimes against police officers resulting in convictions or adjudication withheld outcomes, and a significantly higher proportion of domestic violence charges resulting in convictions alone, compared to control charges. However, after the clustering effect was taken into account, only the effect of BWCs on crimes against police officers remained statistically significant. Conclusion These early results suggest that BWCs have significant evidentiary value that varies by crime type. BWCs may be best suited to capture evidence of crimes committed against police officers and potentially in domestic violence offenses as well.

Abstract BackgroundFront-of-package nutrient warning labels are one promising policy to inform healthier food choices and purchasing decisions. This study aimed to identify the impact of nutrient warning labels on product selection and the ability to correctly identify products with an excess of critical nutrients, among other outcomes in Colombia.MethodsWe conducted an online randomized experiment among 8,061 Colombian adults in October 2020. Participants were randomly assigned to a front-of-package label condition: nutrient warning, guideline daily amounts (GDA), Nutri-Score, or a no-label condition. First, they viewed a fruit drink with added sugar that was labeled per their assigned condition and one without added sugar, which was only labeled in the GDA and Nutri-Score conditions, and completed selection tasks. The primary outcomes were 1) selection of the fruit drink with added sugar as the fruit drink they would rather buy and 2) correctly identifying which fruit drink was higher in sugar. Next, they viewed four food products (cookies, yogurt, sliced bread, and breakfast cereal) with their assigned condition and answered a series of questions. Finally, they selected which of the three label types would most discourage them from consuming a specified ultra-processed food.ResultsFewer participants in the nutrient warning condition (20%) selected the added sugar fruit drink as the product they would rather buy compared to 24% in the GDA condition (p<.01), 29% in the no-label condition, and 33% in the Nutri-Score condition (both, p<.001). More participants in the nutrient warning condition (88%) correctly identified the fruit drink higher in sugar compared to the no-label condition (68%) and the Nutri-Score condition (65%) (both, p<.001). More participants in the GDA condition (91%) correctly identified the fruit drink higher in sugar compared to the nutrient warning condition (p<.01). Most participants (72%) selected the nutrient warning label as most discouraging, while only 20% selected the GDA label and 9% selected the Nutri-Score label.ConclusionsNutrient warning labels are a promising policy strategy to prevent obesity and diet-related non-communicable diseases in Colombia. Future research is needed to understand the impact of nutrient warning labels on actual ultra-processed food purchases in Colombia. Trial Registration: NCT04567004
