The effect of the SIMS Programme versus existing preschool oral healthcare programme on oral hygiene level of preschool children: study protocol for a cluster randomised controlled trial.

ABSTRACT:

Background

Despite the implementation of the preschool oral healthcare programme (POHP) for 5-6-year-old children over the past 3 decades in Malaysia, dental plaque and caries levels in this age group remain high. Among the child-level attributable factors are unhealthy self-care behaviours (poor oral hygiene and high sugary diet). In order to improve the children's oral health, an improved programme called the 'Senyuman Indah Milik Semua' Programme (SIMSP) or 'Beautiful Smile for All' programme is introduced. In this programme, a triad of dental hygienist-teacher-parent works together to improve children's oral hygiene levels compared with the existing POHP that involves dental hygienists only. The aim of this study is to compare the effect of the SIMSP versus the existing POHP on oral hygiene levels of 5-6-year-old children in the Kampar district, Perak state, Malaysia.

Methods

This study is a pragmatic, cluster-randomised, parallel-group, matched pair, controlled trial with blinded outcome assessment. Randomisation is performed using a computer-generated table with a 1:1 allocation comparing the SIMSP and the POHP involving 28 preschools in the Kampar district, Perak, Malaysia. The intervention consists of preschool visits by a group of dental therapists, in-class oral health lessons and daily toothbrushing conducted by class teacher, child home toothbrushing supervised by parents, and infographic oral health messages to parents. The control consists of the existing POHP that involves preschool visits by a group of dental therapists only. The trial lasts for 6 months. Primary outcome variable is the mean plaque score change after 6 months. To determine the feasibility of the SIMSP, a process evaluation will be conducted using the perspectives of dental therapists, teachers, and parents on the appropriateness, effectiveness, facilitators, and barriers to the SIMSP implementation as well as an audit trail to assess the trial intervention.

Discussion

Cluster randomisation may lead to a random effect and cluster selection bias. These factors will be accounted for when analysing the data and interpreting the outcomes. The effectiveness of the SIMSP will be evaluated by comparing the results with those of the POHP.

Project description:IntroductionAchieving a sustained improvement in hand-hygiene compliance is the WHO's first global patient safety challenge. There is no RCT evidence showing how to do this. Systematic reviews suggest feedback is most effective and call for long term well designed RCTs, applying behavioural theory to intervention design to optimise effectiveness.MethodsThree year stepped wedge cluster RCT of a feedback intervention testing hypothesis that the intervention was more effective than routine practice in 16 English/Welsh Hospitals (16 Intensive Therapy Units [ITU]; 44 Acute Care of the Elderly [ACE] wards) routinely implementing a national cleanyourhands campaign). Intervention-based on Goal & Control theories. Repeating 4 week cycle (20 mins/week) of observation, feedback and personalised action planning, recorded on forms. Computer-generated stepwise entry of all hospitals to intervention. Hospitals aware only of own allocation.Primary outcomedirect blinded hand hygiene compliance (%).ResultsAll 16 trusts (60 wards) randomised, 33 wards implemented intervention (11 ITU, 22 ACE). Mixed effects regression analysis (all wards) accounting for confounders, temporal trends, ward type and fidelity to intervention (forms/month used). INTENTION TO TREAT ANALYSIS: Estimated odds ratio (OR) for hand hygiene compliance rose post randomisation (1.44; 95% CI 1.18, 1.76;p<0.001) in ITUs but not ACE wards, equivalent to 7-9% absolute increase in compliance. PER-PROTOCOL ANALYSIS FOR IMPLEMENTING WARDS: OR for compliance rose for both ACE (1.67 [1.28-2.22]; p<0.001) & ITUs (2.09 [1.55-2.81]; p<0.001) equating to absolute increases of 10-13% and 13-18% respectively. Fidelity to intervention closely related to compliance on ITUs (OR 1.12 [1.04, 1.20]; p = 0.003 per completed form) but not ACE wards.ConclusionDespite difficulties in implementation, intention-to-treat, per-protocol and fidelity to intervention, analyses showed an intervention coupling feedback to personalised action planning produced moderate but significant sustained improvements in hand-hygiene compliance, in wards implementing a national hand-hygiene campaign. Further implementation studies are needed to maximise the intervention's effect in different settings.Trial registrationControlled-Trials.com ISRCTN65246961.

Project description:BackgroundHigh levels of childhood obesity have been observed globally over the last three decades. Preschools are promising settings to implement obesity prevention interventions in the early years. The aim of this study was to test the feasibility of a cluster randomised controlled trial of the ToyBox-Scotland preschool obesity prevention intervention.MethodsSix preschools in predominantly deprived areas of Glasgow, UK, were randomised to either the ToyBox intervention (n?=?3) or usual curriculum control group (n?=?3). The intervention ran for 18?weeks from March-June 2018, and consisted of practitioner-led physical activity and sedentary behaviour sessions in preschools, with an additional interactive home component. Primary outcome measures were intervention fidelity, recruitment rates, attrition rates, and compliance with trial procedures. Secondary outcomes were body mass index (BMI) z-score, bioelectrical impedance analysis (BIA), objectively measured physical activity and sedentary time via activPAL accelerometer, and parent-reported home eating, snacking, and water consumption.ResultsThe preschool component of the intervention was implemented with high fidelity (64%), while the home component was implemented with low fidelity (41%). A cluster-level recruitment rate of 10% was achieved, and the individual-level recruitment rate was 18% (42/233 children, mean age 4.4?years; 17 girls). The attrition rate was 14%, and compliance rates varied considerably by the outcome. Compliance was highest for BMI (86%), while 19% of the sample returned valid accelerometer data for both baseline and follow-up and the parental questionnaire response rate was 23%. Both intervention and control groups showed small increases in BMI z-scores at follow-up of 0.02 and 0.06, respectively. Both groups had small decreases in physical activity and increases in sedentary time at follow-up.ConclusionsBefore progression to an effectiveness trial, additional procedures should be considered to improve recruitment rates, compliance with outcome measures, and implementation of the home-based component of the ToyBox-Scotland intervention.Trial registrationISRCTN12831555.

Project description:The growing population living with chronic conditions calls for efficient healthcare-planning and effective care. Implementing disease-management-programmes is one option for responding to this demand. Knowledge is scarce about the effect of implementation processes and their effect on patients; only few studies have reported the effectiveness of disease-management-programmes targeting patients with chronic obstructive pulmonary disease (COPD). The objective of this paper was to determine the effect on healthcare-utilization of an active implementation model for a disease-management-programme for patients with one of the major multimorbidity diseases, COPD.The standard implementation of a new disease-management-programme for COPD was ongoing during the study-period from November 2008 to November 2010 in the Central Denmark Region. We wanted to test a strategy using Breakthrough Series, academic detailing and lists of patients with COPD. It targeted GPs and three hospitals serving approx. 60,000 inhabitants aged 35 or older and included interventions directed at professionals, organisations and patients. The study was a non-blinded block- and cluster-randomised controlled trial with GP-practices as the unit of randomisation. In Ringkoebing-Skjern Municipality, Denmark, 16 GP-practices involving 38 GPs were randomised to either the intervention-group or the control-group. A comparable neighbouring municipality acted as an external-control-group which included nine GP-practices with 25 GPs. An algorithm based on health-registry-data on lung-related contacts to the healthcare-system identified 2,736 patients who were alive at the end of the study-period. The population included in this study counted 1,372 (69.2%) patients who responded to the baseline questionnaire and confirmed their COPD diagnosis; 458 (33.4%) patients were from the intervention-group, 376 (27.4%) from the control-group and 538(39.2%) from the external-control-group. The primary outcome was adherence to the disease-management-programme measured at patient-level by use of specific services from general practice. Secondary outcomes were use of out-of-hours-services, outpatient-clinic, and emergency-department and hospital-admissions.The intervention practices provided more planned preventive consultations, additional preventive consultations and spirometries than non-intervention practices. A comparison of the development in the intervention practices with the development in the control-practices showed that the intervention resulted in more planned preventive-consultations, fewer conventional consultations and fewer patients admitted without a lung-related-diagnosis.Use of the active implementation model for the disease-management-programme for COPD changed the healthcare utilization in accordance with the programme.Clinicaltrials.gov identifier: NCT01228708.
