Effect of a complex intervention to improve post-vision screening referral compliance among pre-school children in China: A cluster randomized clinical trial.

ABSTRACT: Background:We investigated whether specific appointments for quality-assured care could increase referral uptake, often low in China, in children's vision screening. Methods:We randomized children aged 4-7 years in Yudu, Jiangxi, China, by school to Control (free school-based eye screening, parents of children failing screening recommended for further examination [usual practice]) or Intervention (identical examinations, with parents additionally provided with specific appointments for further examinations by quality-assured doctors at a designated local hospital). Both groups could select any hospital for referral exams, which were not free. Six months after screening, parents were interviewed on referral compliance at any hospital (primary outcome) and potential determinants. This trial is registered at the ClinicalTrials.gov, number NCT03251456. Findings:Among 9936 children at 63 schools randomized to Intervention (32 schools, 5053 [50·9%] children) or Control (31 schools, 4883 [49·1%] children), 1114 children (11·2%) failed screening. Among 513 referred Intervention children (46·1%, 32 schools, mean age 5·36 years, 53·0% boys) and 601 referred Control children (53·9%, 31 schools, mean age 5·30 years, 57·7% boys), 104 (20·3%) and 135 (22·5%) were lost to follow-up respectively. Under Intention to Treat analysis, assuming children lost to follow-up were non-compliant, Intervention children had significantly higher compliance than Controls (308/513 = 60·0% vs. 225/601 = 37·4%, P < 0·001). In regression models, Intervention group membership (Relative risk [RR] 1·53, 95% confidence interval, 1·36-1·72), travel time to hospital (RR: 0·97, 0·95-0·999), baseline glasses wear (RR: 1·37, 1·17-1·60), strabismus (RR: 1·17, 1·01-1·36) and worse uncorrected vision (RR: 1·41, 1·03-1·92) were associated with compliance. Interpretation:Providing specific appointments for quality-assured eye care improved referral compliance in this setting.

Project description:INTRODUCTION:The first years of school are critical in establishing a foundation for positive long-term academic, social and well-being outcomes. Mindfulness-based interventions may help students transition well into school, but few robust studies have been conducted in this age group. We aim to determine whether compared with controls, children who receive a mindfulness intervention within the first years of primary school have better: (1) immediate attention/short-term memory at 18 months post-randomisation (primary outcome); (2) inhibition, working memory and cognitive flexibility at 18 months post-randomisation; (3) socio-emotional well-being, emotion-regulation and mental health-related behaviours at 6 and 18 months post-randomisation; (4) sustained changes in teacher practice and classroom interactions at 18 months post-randomisation. Furthermore, we aim to determine whether the implementation predicts the efficacy of the intervention, and the cost effectiveness relative to outcomes. METHODS AND ANALYSIS:This cluster randomised controlled trial will be conducted in 22 primary schools in disadvantaged areas of Melbourne, Australia. 826 students in the first year of primary school will be recruited to detect between groups differences of Cohen's d=0.25 at the 18-month follow-up. Parent, teacher and child-assessment measures of child attention, emotion-regulation, executive functioning, socio-emotional well-being, mental health-related behaviour and learning, parent mental well-being, teacher well-being will be collected 6 and 18 months post-randomisation. Implementation factors will be measured throughout the study. Intention-to-treat analyses, accounting for clustering within schools and classes, will adopt a two-level random effects linear regression model to examine outcomes for the intervention versus control students. Unadjusted and analyses adjusted for baseline scores, baseline age, gender and family socioeconomic status will be conducted. ETHICS AND DISSEMINATION:Ethics approval has been received by the Human Research Ethics Committee at the University of Melbourne. Findings will be reported in peer-review publications, national and international conference presentations and research snapshots directly provided to participating schools and families.

Project description:ImportanceEarly intervention for substance use is critical to improving adolescent outcomes. Studies have found promising results for Screening, Brief Intervention, and Referral to Treatment (SBIRT), but little research has examined implementation.ObjectiveTo compare SBIRT implementation in pediatric primary care among trained pediatricians, pediatricians working in coordination with embedded behavioral health care practitioners (BHCPs), and usual care (UC).Design, setting, and participantsThe study is a 2-year (November 1, 2011, through October 31, 2013), nonblinded, cluster randomized, hybrid implementation and effectiveness trial examining SBIRT implementation outcomes across 2 modalities of implementation and UC. Fifty-two pediatricians from a large general pediatrics clinic in an integrated health care system were randomized to 1 of 3 SBIRT implementation arms; patients aged 12 to 18 years were eligible.InterventionsTwo modes of SBIRT implementation, (1) pediatrician only (pediatricians trained to provide SBIRT) and (2) embedded BHCP (BHCP trained to provide SBIRT), and (3) UC.Main outcomes and measuresImplementation of SBIRT (primary outcome), which included assessments, brief interventions, and referrals to specialty substance use and mental health treatment.ResultsThe final sample included 1871 eligible patients among 47 pediatricians; health care professional characteristics did not differ across study arms. Patients in the pediatrician-only (adjusted odds ratio [AOR], 10.37; 95% CI, 5.45-19.74; P < .001) and the embedded BHCP (AOR, 18.09; 95% CI, 9.69-33.77; P < .001) arms had higher odds of receiving brief interventions compared with patients in the UC arm. Patients in the embedded BHCP arm were more likely to receive brief interventions compared with those in the pediatrician-only arm (AOR, 1.74; 95% CI, 1.31-2.31; P < .001). The embedded BHCP arm had lower odds of receiving a referral compared with the pediatrician-only (AOR, 0.58; 95% CI, 0.43-0.78; P < .001) and UC (AOR, 0.65; 95% CI, 0.48-0.89; P = .006) arms; odds of referrals did not differ between the pediatrician-only and UC arms.Conclusions and relevanceThe intervention arms had better screening, assessment, and brief intervention rates than the UC arm. Patients in the pediatrician-only and UC arms had higher odds of being referred to specialty treatment than those in the embedded BHCP arm, suggesting lingering barriers to having pediatricians fully address substance use in primary care. Findings also highlight age and ethnic groups less likely to receive these important services.Trial registrationClinicaltrials.gov Identifier: NCT02408952.

Project description:Background The control of hypertension is low in low- and middle-income countries like India. We evaluated the effects of a nurse-facilitated educational intervention in improving the control rate of hypertension among school teachers in India. Methods and Results This was a cluster-randomized controlled trial involving 92 schools in Kerala, which were randomly assigned equally into a usual care group and an intervention group. Participants were 402 school teachers (mean age, 47 years; men, 29%) identified with hypertension. Participants in both study groups received a leaflet containing details of a healthy lifestyle and the importance of regular intake of antihypertensive medication. In addition, the intervention participants received a nurse-facilitated educational intervention on hypertension control for 3 months. The primary outcome was hypertension control. Key secondary outcomes included systolic blood pressure, diastolic blood pressure, and the proportion of participants taking antihypertensive medications. For the primary outcome, we used mixed-effects logistic regression models. Two months after a 3-month educational intervention, a greater proportion of intervention participants (49.0%) achieved hypertension control than the usual care participants (38.2%), with an odds ratio of 1.89 (95% CI, 1.06-3.35), after adjusting for baseline hypertension control. The odds of taking antihypertensive medications were 1.6 times higher in the intervention group compared with the usual care group (odds ratio, 1.62; 95% CI, 1.08-2.45). The reduction in mean systolic blood pressure was significantly greater in the intervention group by 4.2 mm Hg (95% CI, -7.2 to -1.1) than in the usual care group. Conclusions A nurse-facilitated educational intervention was effective in improving the control and treatment rates of hypertension as well as reducing systolic blood pressure among schoolteachers with hypertension.

Project description:BACKGROUND:Interventions to improve hand hygiene (HH) compliance are a key element in the practice infection prevention and control. It was our objective to assess the effect of a multimodal intervention on HH compliance at a tertiary care university hospital. As a secondary objective, we investigated the effect of the intervention on the occurrence of device-associated bloodstream infections. METHODS:We performed a single centre cluster randomised controlled trial at a university hospital in Germany. Twenty peripheral wards were invited to participate and randomly assigned to either the intervention (n?=?10) or control group (n?=?10). Quarterly, specifically trained student employees conducted direct compliance observations in all twenty wards. The intervention entailed dissemination of teaching materials on aseptic procedures, equipment with flexibly mountable alcoholic hand rub dispensers, and quarterly feedback on HH compliance. RESULTS:In total, 21,424 HH opportunities were observed. Overall, compliance did not change significantly in either group (intervention group: 59% vs. 61% (1482 HH actions for 2494 HH opportunities vs. 5033 HH actions for 8215 HH opportunities), odds ratio (OR) 1.08 (95% confidence interval (CI95) 0.88, 1.33)); control group: 59% vs. 60% (1457 HH actions for 2484 HH opportunities vs. 4948 HH actions for 8231 HH opportunities), OR 1.06 (CI95 0.84, 1.35)). Compliance prior to aseptic procedures improved significantly in the intervention group from 44% (168 HH actions for 380 HH opportunities) to 53% (764 HH actions for 1452 HH opportunities) (OR 1.40 (CI95 1.04, 1.89), p?=?0.03), while no significant increase was noted in the control group. In the intervention group, significantly fewer device-associated bloodstream infections per 1000 patient-days occurred than in the control group (84 vs. 123, incidence rate ratio 0.61 (CI95 0.46, 0.81), p?<?0.01). CONCLUSIONS:The lack of a significant overall improvement of HH compliance demonstrated that comprehensive implementation of HH interventions in multiple wards simultaneously is difficult. However, through targeted intervention measures, we were able to significantly increase HH compliance before aseptic procedures.

Project description:BACKGROUND: Early interventions proved to be able to improve prognosis in acute stroke patients. Prompt identification of symptoms, organised timely and efficient transportation towards appropriate facilities, become essential part of effective treatment. The implementation of an evidence based pre-hospital stroke care pathway may be a method for achieving the organizational standards required to grant appropriate care. We performed a systematic search for studies evaluating the effect of pre-hospital and emergency interventions for suspected stroke patients and we found that there seems to be only a few studies on the emergency field and none about implementation of clinical pathways. We will test the hypothesis that the adoption of emergency clinical pathway improves early diagnosis and referral in suspected stroke patients. We designed a cluster randomised controlled trial (C-RCT), the most powerful study design to assess the impact of complex interventions. The study was registered in the Current Controlled Trials Register: ISRCTN41456865--implementation of pre-hospital emergency pathway for stroke--a cluster randomised trial. METHODS/DESIGN: Two-arm cluster-randomised trial (C-RCT). 16 emergency services and 14 emergency rooms were randomised either to arm 1 (comprising a training module and administration of the guideline), or to arm 2 (no intervention, current practice). Arm 1 participants (152 physicians, 280 nurses, 50 drivers) attended an interactive two sessions course with continuous medical education CME credits on the contents of the clinical pathway. We estimated that around 750 patients will be met by the services in the 6 months of observation. This duration allows recruiting a sample of patients sufficient to observe a 30% improvement in the proportion of appropriate diagnoses. Data collection will be performed using current information systems. Process outcomes will be measured at the cluster level six months after the intervention. We will assess the guideline recommendations for emergency and pre-hospital stroke management relative to: 1) promptness of interventions for hyperacute ischaemic stroke; 2) promptness of interventions for hyperacute haemorrhagic stroke 3) appropriate diagnosis. Outcomes will be expressed as proportions of patients with a positive CT for ischaemic stroke and symptoms onset < or = 6 hour admitted to the stroke unit. DISCUSSION: The fields in which this trial will play are usually neglected by randomised controlled trial (RCT). We have chosen the cluster-randomised controlled trial (C-RCT) to address the issues of contamination, adherence to real practice, and community dimension of the intervention, with a complex definition of clusters and an extensive use of routine data to collect the outcomes.
