Evidence of high bednet usage from a list randomization experiment in rural Gambia

Abstract Background Recording behaviours that have the potential to impact health can be doubly challenging if the behaviour takes place in private spaces that cannot be observed directly and where there is potential for social desirability bias, i.e. where the respondent may give an answer that they think the recorder wants to hear. Sleeping under a long-lasting insecticidal net (LLIN) is an important intervention for malaria prevention, yet it is difficult to gauge the extent to which coverage (how many nets are in the community) differs from usage (how many people sleep under a net). We employed a novel method, list randomization, which partially obscures respondents' answers to sensitive questions, as a mean to provide an accurate estimate of LLIN usage in The Gambia.Methods We surveyed 196 residents from 196 households recruited into a randomised controlled trial assessing the effect of a housing intervention on malaria. In the current experiment, 98 of the 196 study participants were randomly assigned to the control group and received a four-question list about non-sensitive behaviours; the other participants in the intervention group, received the same list, with the addition of one question on a sensitive behaviour; whether or not they had used a bednet the previous night. Participants were read the list of questions and then said how many of the statements were true. We estimated bednet usage by calculating the difference in means between the total number of affirmative items between the two groups, and quantified uncertainty using a t-test.Results The mean number of affirmative responses in the control group was 2.60 of four statements (95% confidence interval, 95% CI, = 2.50-2.70), compared with 3.68 (95% CI = 3.59-3.78) in the intervention group. Such difference (1.08; 95% CI = 94.9-100%) suggests approximately 100% bednet usage.Conclusions Our findings suggest complete universal bednet usage in the study area. Further validation of the list randomization method in areas with lower net coverage is required.

IntroductionPain caused by routine immunisations is distressing to children, their parents and those administering injections. If poorly managed, it can lead to anxiety about future medical procedures, needle phobia and avoidance of future vaccinations and other medical treatment. Several strategies, such as distraction, are used to manage the distress associated with routine immunisations. Virtual reality (VR), a technology which transports users into an immersive ‘virtual world’, has been used to manage pain and distress in various settings such as burns dressing changes and dental treatments. In this study, we aim to compare the effectiveness of VR to standard care in a general practice setting as a distraction technique to reduce pain and distress in 4-year-old children receiving routine immunisations.Methods and analysisThe study is a randomised controlled clinical trial comparing VR with standard care in 100 children receiving routine 4-year-old vaccination. Children attending a single general practice in metropolitan Melbourne, Australia will be allocated using blocked randomisation to either VR or standard care. Children in the intervention group will receive VR intervention prior to vaccination in addition to standard care; the control group will receive standard care. The primary outcome is the difference in the child’s self-rated pain scores between the VR intervention and control groups measured using The Faces Pain Scale-Revised. Secondary outcomes include another measure of self-rated pain (the Poker Chip Tool), parent/guardian and healthcare provider ratings of pain (standard 100 mm visual analogue scales) and adverse effects.Ethics and disseminationEthics approval has been obtained in Australia from the Royal Australian College of General Practitioners National Research and Evaluation Ethics Committee (NREEC 18-010). Recruitment commenced in July 2019. We plan to submit study findings for publication in a peer-reviewed journal and presentation at relevant conferences.Trial registration numberACTRN12618001363279.

IntroductionSalt intake in China is twice the upper limit recommended by the WHO, and nearly 80% of salt is added during cooking. This study will develop a package of salt reduction interventions targeting home cooks and evaluate its effectiveness and feasibility for scale-up.Methods and analysisA cluster randomised controlled trial design is adopted in this study, which will be conducted in six provinces covering northern, central and southern China. For each province, 10 communities/villages (clusters) with 13 families (one cook and one adult family member) will be selected in each cluster for evaluation. In total, 780 home cooks and 780 adult family members will be recruited. The home cooks in the intervention group will be provided with the intervention package, including community-based standardised offline and online health education and salt intake monitoring. The duration of the intervention will be 1 year. The primary outcome is the difference between the intervention and control group in change in salt intake as measured by 24 hours urinary sodium from baseline to the end of the trial. The secondary outcome is the difference between the two groups in the change in salt-related knowledge, attitude and practice and blood pressure (BP).Ethics and disseminationThe study has been approved by The Queen Mary Research Ethics Committee (QMERC2018/13) and Institutional Review Board of the Chinese Center for Disease Control and Prevention (No. 201801). The study findings will be disseminated widely through conference presentations and peer-reviewed publications and the general media.Trial registration numberChiCTR1800016804.

BackgroundRepetition of self-poisoning is common.AimsTo report the 24-month outcomes of a non-obligatory postcard intervention (plus treatment as usual) compared with treatment as usual.MethodIn a randomised-controlled trial (Zelen design) conducted in Newcastle, Australia, eight postcards were sent to participants over a 12-month period. The principal outcomes were the proportion of participants with one or more repeat episodes of self-poisoning and the number of repeat episodes per person.ResultsNo significant reduction was observed in the proportion of people repeating self-poisoning in the intervention group (21.2%, 95% CI 17.0–25.3) compared with the control group (22.8%, 95% CI 18.7–27.0;χ2=0.32, d.f. = 1,P= 0.57); the difference between groups was −1.7% (95% CI −7.5 to 4.2). There was a significant reduction in the rate of repetition, with an incidence risk ratio of 0.49 (95% CI 0.33–0.73).ConclusionsA postcard intervention maintained the halving of the rate of repetition of hospital-treated self-poisoning events over a 2-year period, although it did not significantly reduce the proportion of individuals who repeated self-poisoning.

Pragmatic Randomised Controlled Trial

Abstract Background Type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD) are two chronic diseases that cause a tremendous burden. To reduce this burden, several programmes for optimising the care for these diseases have been developed. In Germany, so-called disease management programmes (DMPs), which combine components of Disease Management and the Chronic Care Model, are applied. These DMPs have proven effective. Nevertheless, there are opportunities for improvement. Current DMPs rarely address self-management of the disease, make no use of peer support, and provide no special assistance for persons with low health literacy and/or low patient activation. The study protocol presented here is for the evaluation of a programme that addresses these possible shortcomings and can be combined with current German DMPs for T2DM and CHD. This programme consists of four components: Meetings of peer support groups Personalised telephone-based health coaching for patients with low literacy and/or low patient activation Personalised patient feedback A browser-based web portal Methods Study participants will be adults enrolled in a DMP for T2DM and/or CHD and living in North Rhine-Westphalia, a state of the Federal Republic of Germany. Study participants will be recruited with the assistance of their general practitioners by the end of June 2021. Evaluation will be performed as a pragmatic randomised controlled trial with one intervention group and one waiting control group. The intervention group will receive the intervention for 18 months. During this time, the waiting control group will continue with usual care and the usual measures of their DMPs. After 18 months, the waiting control group will also receive a shortened intervention. The primary outcome is number of hospital days. In addition, the effects on self-reported health-state, physical activity, nutrition, and eight different psychological variables will be investigated. Differences between values at month 18 and at the beginning will be compared to judge the effectiveness of the intervention. Discussion If the intervention proves effective, it may be included into the DMPs for T2DM and CHD. Trial registration The study was registered in the German Clinical Trials Registry (Deutsches Register Klinischer Studien (DRKS)) in early 2019 under the number 00020592. This registry has been affiliated with the WHO Clinical Trials Network (https://www.drks.de/drks_web/setLocale_EN.do) since 2008.

ObjectiveDetermine the adherence to and effectiveness of an 8-week home exercise programme for children with disabilities delivered using Physitrack, an online exercise prescription tool, compared with traditional paper-based methods.DesignSingle-blinded, parallel-groups, randomised controlled trial (RCT).SettingIntervention took place in participants’ homes in Western Australia.ParticipantsChildren aged 6 to 17 years, with neurodevelopmental disabilities including cerebral palsy (CP), receiving community therapy services.InterventionAll participants completed an individualised home exercise programme, which was delivered to the intervention group using Physitrack and conventional paper-based methods for the control group.Primary outcome measuresAdherence to exercise programme, goal achievement and exercise performance.Secondary outcome measuresEnjoyment, confidence and usability of Physitrack.ResultsFifty-four participants with CP (n=37) or other neurodevelopmental disabilities (n=17) were recruited. Fifty-three were randomised after one early withdrawal. Forty-six completed the 8-week programme, with 24 in the intervention group and 22 in the control group. There was no difference between the two groups for percentage of exercises completed (intervention (n=22): 62.8% (SD 27.7), control (n=22): 55.8% (SD 19.4), between group mean difference −7.0% (95% CI: −21.6 to 7.5, p=0.34)). Both groups showed significant improvement in their self-rated performance of individualised goal activities, however there was no statistically significant difference between groups for goal achievement, quality of exercise performance, enjoyment, confidence or preferred method of delivery. There were no adverse events.ConclusionPhysitrack provides a therapist with a new means of providing an exercise programme with online tools such as exercise videos, but our preliminary findings indicate that it may be no better than a traditional paper-based method for improving exercise adherence or the other outcomes measured. Exercise programmes remain an intervention supported by evidence, but a larger RCT is required to fully evaluate online delivery methods.Trial registration detailsAustralian New Zealand Clinical Trials Registry; ACTRN12616000743460.

Abstract Background Employers express a need for support during sickness absence and return to work (RTW) of cancer survivors. Therefore, a web-based intervention (MiLES) targeted at employers with the objective of enhancing cancer survivors’ successful RTW has been developed. This study aimed to assess feasibility of a future definitive randomised controlled trial (RCT) on the effectiveness of the MiLES intervention. Also preliminary results on the effectiveness of the MiLES intervention were obtained. Methods A randomised feasibility trial of 6 months was undertaken with cancer survivors aged 18–63 years, diagnosed with cancer < 2 years earlier, currently in paid employment, and sick-listed < 1 year. Participants were randomised to an intervention group, with their employer receiving the MiLES intervention, or to a waiting-list control group (2:1). Feasibility of a future definitive RCT was determined on the basis of predefined criteria related to method and protocol-related uncertainties (e.g. reach, retention, appropriateness). The primary effect measure (i.e. successful RTW) and secondary effect measures (e.g. quality of working life) were assessed at baseline and 3 and 6 months thereafter. Results Thirty-five cancer survivors were included via medical specialists (4% of the initially invited group) and open invitations, and thereafter randomised to the intervention (n = 24) or control group (n = 11). Most participants were female (97%) with breast cancer (80%) and a permanent employment contract (94%). All predefined criteria for feasibility of a future definitive RCT were achieved, except that concerning the study’s reach (90 participants). After 6 months, 92% of the intervention group and 100% of the control group returned to work (RR: 0.92, 95% CI: 0.81–1.03); no difference were found with regard to secondary effect measures. Conclusions With the current design a future definitive RCT on the effectiveness of the MiLES intervention on successful RTW of cancer survivors is not feasible, since recruitment of survivors fell short of the predefined minimum for feasibility. There was selection bias towards survivors at low risk of adverse work outcomes, which reduced generalisability of the outcomes. An alternative study design is needed to study effectiveness of the MiLES intervention. Trial registration The study has been registered in the Dutch Trial Register (NL6758/NTR7627).

Pediatric clinical trials allow for the testing of appropriate and effective treatments for children. However, some challenges exist with recruitment. This study examined the effectiveness of DigiKnowIt News, an interactive, multimedia website (which includes activities, videos, and comic books) designed to educate children about clinical trials. A randomized controlled trial was conducted in 2018 with 91 participants ( M age = 10.92 years; SD = 2.06). Participants were randomly assigned to intervention or wait-list control groups and completed questionnaires at pretest and posttest (1 week later) about their knowledge, attitudes, beliefs about clinical trials, and self-efficacy for participating in clinical trials. Participants in the intervention group received access to DigiKnowIt News between pretest and posttest and completed a satisfaction questionnaire at posttest. At the end of the study, participants in the wait-list control group were offered the option to use the website and complete a satisfaction questionnaire. At posttest, participants in the intervention group, compared to participants in the wait-list control group, had more knowledge about clinical trials and more reported confidence for participating in clinical trials. Participants reported high levels of satisfaction with DigiKnowIt News. The findings suggest that an educational website can improve factors related to increasing rates of participation in clinical trials.

IntroductionPhysical activity is one of the major modifiable factors for promotion of public health. Although it has been reported that financial incentives would be effective for promoting health behaviours such as smoking cessation or attendance for cancer screening, few randomised controlled trials (RCTs) have examined the effect of financial incentives for increasing the number of daily steps among individuals in a community setting. The aim of this study is to investigate the effects of financial incentives for increasing the number of daily steps among community-dwelling adults in Japan.Methods and analysisThis study will be a two-arm, parallel-group RCT. We will recruit community-dwelling adults who are physically inactive in a suburban area (Nakayama) of Sendai city, Japan, using leaflets and posters. Participants that meet the inclusion criteria will be randomly allocated to an intervention group or a waitlist control group. The intervention group will be offered a financial incentive (a chance to get shopping points) if participants increase their daily steps from their baseline. The primary outcome will be the average increase in the number of daily steps (at 4–6 weeks and 7–9 weeks) relative to the average number of daily steps at the baseline (1–3 weeks). For the sample size calculation, we assumed that the difference of primary outcome would be 1302 steps.Ethics and disseminationThis study has been ethically approved by the research ethics committee of Tohoku University Graduate School of Medicine, Japan (No. 2018-1-171). The results will be submitted and published in a peer-reviewed scientific journal.Trial registration numberUMIN000033276; Pre-results.

Introduction. The aim of this study was to explore the learning effect of engaging trainees by assessing peer performance during simulation-based training.Methods. Eighty-four final year medical students participated in the study. The intervention involved trainees assessing peer performance during training. Outcome measures were in-training performance and performance, both of which were measured two weeks after the course. Trainees’ performances were videotaped and assessed by two expert raters using a checklist that included a global rating. Trainees’ satisfaction with the training was also evaluated.Results. The intervention group obtained a significantly higher overall in-training performance score than the control group: mean checklist score 20.87 (SD 2.51) versus 19.14 (SD 2.65)P=0.003and mean global rating 3.25 SD (0.99) versus 2.95 (SD 1.09)P=0.014. Postcourse performance did not show any significant difference between the two groups. Trainees who assessed peer performance were more satisfied with the training than those who did not: mean 6.36 (SD 1.00) versus 5.74 (SD 1.33)P=0.025.Conclusion. Engaging trainees in the assessment of peer performance had an immediate effect on in-training performance, but not on the learning outcome measured two weeks later. Trainees had a positive attitude towards the training format.

Abstract Background Long-term complaints after caesarean section, such as postmenstrual spotting, dysmenorrhea, dyspareunia, or chronic pelvic pain, are frequently described in relation to the presence of a niche. A post-caesarean niche is defined as an indentation in the myometrium at the site of the uterine scar. Two independent prospective cohort studies reported that the presence of a niche after caesarean section increases the risk of postmenstrual spotting for more than 2 days from 15 to 30%. Postmenstrual spotting may be caused by a mechanical outflow problem, with the retention of menstrual blood in a niche, or by the accumulation of blood because of impaired uterine contractions at the site of the niche. Additionally, newly formed fragile vessels in the niche may play a role in the formation of blood or fluid in the niche and uterine cavity. Objective The aim of this study was to compare the effectiveness of a hysteroscopic niche resection versus no treatment in women with postmenstrual spotting and a uterine caesarean scar defect. Methods This trial is a randomised controlled trial that provides evidence for the (cost) effectiveness of hysteroscopic resection of a niche versus expectant management in women with niche related postmenstrual spotting. It was carried out on 28 cases divided into two equal group. The study was conducted at Ain Shams University on the women reporting postmenstrual spotting after a caesarean section. The primary outcome was the number of days of postmenstrual spotting 6 months after randomization. Secondary outcomes were spotting at the end of menstruation, intermenstrual spotting, dysuria, sonographic niche measurements, quality of life, women’s satisfaction, sexual function, and additional therapy. Outcomes were measured at 3 months and, also at 6 months after randomization. Results The results of this study show a significant improvement in interventional group after 3 months more than the control group in bleeding micturition characteristics which includes total days of spotting, spotting end of menstruation, intermenstral spotting, discomfort from spotting, dysmenorrhea and daily pain during micturition, after 6 months the two group improved but the interventional group was significantly higher than control group. Regarding the radiological assessment it was found that there was a significant improvement in intervention group more than the control group after 3 months, also the control group improved after 6 months also, but the intervention groups was significantly higher than the control group. The quality of life show a significant increasing in intervention group more than the control group after 3 months of intervention, at the end of follow up the intervention group was significantly higher in quality of life more than the control group. Conclusion A hysteroscopic niche resection reduces postmenstrual spotting, and the discomfort from spotting, compared with expectant management after 3 months of follow-up in women with a niche with a residual myometrium of at least 3 mm.
