Knowledge of childhood burn risks and burn first aid: Cool Runnings

AIM

The high incidence of hot beverage scalds among young children has not changed in the past 15 years, but preventive campaigns have been scarce. A novel approach was used to engage mothers of young children in an app-based hot beverage scald prevention campaign 'Cool Runnings'. This paper provides baseline data for this randomised controlled trial (RCT).

METHOD

Queensland-based mothers aged 18+ years with at least one child aged 5-12 months were recruited via social media to Cool Runnings, which is a two-group, parallel, single-blinded RCT.

RESULTS

In total, 498 participants from across Queensland completed the baseline questionnaire. The most common source of burn first aid information was the internet (79%). One-third (33%) correctly identified hot beverage scalds as the leading cause of childhood burns, 43% knew the age group most at risk. While 94% reported they would cool a burn with water, only 10% reported the recommended 20min duration. After adjusting for all relevant variables, there were two independent predictors of adequate burn first aid knowledge: first aid training in the past year (OR=3.32; 95% CI 1.8 to 6.1) and smoking status (OR=0.17; 95% CI 0.04 to 0.7).

CONCLUSION

In this study, mothers of young children were largely unaware how frequently hot beverage scalds occur and the age group most susceptible to them. Inadequate burn first aid knowledge is prevalent across mothers of young children; there is an urgent and compelling need to improve burn first aid knowledge in this group. Given the high incidence of hot beverages scalds in children aged 6-24 months, it is important to target future burn prevention/first aid campaigns at parents of young children.

The Adoption of Social Media to Recruit Participants for the Cool Runnings Randomized Controlled Trial in Australia

BACKGROUND

Using social media to recruit specific populations for research studies is gaining popularity. Given that mothers of young children are the most active on social media, and young children are the most at risk of preventable burn injuries, social media was used to recruit mothers of young children to a burn prevention intervention.

OBJECTIVE

The aim of this paper was to describe the social media recruitment methods used to enroll mothers of young children to the app-based burn prevention intervention Cool Runnings.

METHODS

Participants were recruited via paid Facebook and Instagram advertisements to a 2-group, parallel, single-blinded, randomized controlled trial (RCT). The advertisements were targeted at women 18 years and older, living in Queensland, Australia, with at least 1 child aged 5 to 12 months at the time of recruitment.

RESULTS

Over the 30-day recruitment period from January to February 2016, Facebook and Instagram advertisements reached 65,268 people, generating 2573 link clicks, 1161 app downloads, and 498 enrolled participants to the Cool Runnings RCT. The cost per enrolled participant was Aus $13.08. Saturdays were the most effective day of the week for advertising results. The most popular time of day for enrolments was between 5 to 11 PM. This recruitment strategy campaign resulted in a broad reach of participants from regional, rural, and remote Queensland. Participants were representative of the population in regard to age and education levels.

CONCLUSIONS

To our knowledge, this is the first use of social media recruitment for an injury prevention campaign. This recruitment method resulted in the rapid and cost-effective recruitment of participants with social, geographic, and economic diversity that were largely representative of the population.

Cool Runnings - an app-based intervention for reducing hot drink scalds: study protocol for a randomised controlled trial

Background

Globally, burns are the fifth leading cause of non-fatal children’s injuries, and the leading cause of childhood burns is hot beverage scalds. Although there have been a number of programmes aimed at preventing scalds in children, very few have specifically addressed hot beverage scalds, and fewer have reported a reduction in injury rates. In Australia, hot beverage scalds account for 18 % of all childhood burns – a figure that has remained constant for the past decade.

Innovative new technologies, such as Smartphone applications (apps), present a novel way for delivering individual-level injury prevention messages. The low cost, scalability and broad reach make this technology an ideal channel for health interventions.

One of the latest methods being used in health-related apps aimed at behaviour change is gamification. Gamification uses the gaming principles of rewards, competition and personalisation to engage participants and motivate them towards preferred behaviours.

This intervention will use a Smartphone app-based platform that combines gamification and behaviour-change strategies to increase knowledge and awareness of hot beverage scald risks and burn first aid among mothers of young children.

Methods/design

This is a two-group, parallel, single-blinded randomised control trial (RCT) to evaluate the efficacy of a Smartphone app-based injury prevention intervention. The primary outcome measure is change in knowledge. Change in knowledge is measured in three components: knowledge of correct burns first aid; knowledge of the main cause of burns/scalds in children aged 0–15yrs; knowledge of the main age group at risk for burns/scalds. The secondary outcome measures relate to the gamification methods, measuring participants frequency of engagement with the Cool Runnings app. Queensland-based mothers aged 18+ years who own a Smartphone and have at least one child aged 5–12 months are eligible to participate.

Discussion

To our knowledge, this is the first study to evaluate an app-based delivery of injury prevention messages, and the first study to test the efficacy of gamification techniques in an injury prevention intervention. If this intervention is found to be effective, this RCT will provide a platform for targeting other childhood injury prevention campaigns.

Gene expression levels as endophenotypes in genome-wide association studies of Alzheimer disease

BACKGROUND

Late-onset Alzheimer disease (LOAD) is a common disorder with a substantial genetic component. We postulate that many disease susceptibility variants act by altering gene expression levels.

METHODS

We measured messenger RNA (mRNA) expression levels of 12 LOAD candidate genes in the cerebella of 200 subjects with LOAD. Using the genotypes from our LOAD genome-wide association study for the cis-single nucleotide polymorphisms (SNPs) (n = 619) of these 12 LOAD candidate genes, we tested for associations with expression levels as endophenotypes. The strongest expression cis-SNP was tested for AD association in 7 independent case-control series (2,280 AD and 2,396 controls).

RESULTS

We identified 3 SNPs that associated significantly with IDE (insulin degrading enzyme) expression levels. A single copy of the minor allele for each significant SNP was associated with approximately twofold higher IDE expression levels. The most significant SNP, rs7910977, is 4.2 kb beyond the 3' end of IDE. The association observed with this SNP was significant even at the genome-wide level (p = 2.7 x 10(-8)). Furthermore, the minor allele of rs7910977 associated significantly (p = 0.0046) with reduced LOAD risk (OR = 0.81 with a 95% CI of 0.70-0.94), as expected biologically from its association with elevated IDE expression.

CONCLUSIONS

These results provide strong evidence that IDE is a late-onset Alzheimer disease (LOAD) gene with variants that modify risk of LOAD by influencing IDE expression. They also suggest that the use of expression levels as endophenotypes in genome-wide association studies may provide a powerful approach for the identification of disease susceptibility alleles.

Home-based study of anti-HIV drug regimen adherence among HIV-infected women: feasibility and preliminary results

Collection of antiretroviral medication adherence data in the homes of HIV-infected people may have methodological advantages that can improve data quality. However, the feasibility of this approach has not been established. In addition, data on adherence, and its predictors, among HIV-infected women have been limited. Sixty-three HIV-positive women who were prescribed at least one antiretroviral drug in the last month were interviewed in their homes. A standard instrument was used to collect data on all antiretroviral medications prescribed and taken in the three days prior to the interview. Data were also collected on factors thought potentially to affect the ability to be adherent. The results of this study suggest that it is feasible to conduct home-based adherence research. Sixty-seven per cent reported taking all prescribed antiretroviral medication doses. One-third took a sub-optimal dose putting themselves at increased risk of treatment failure and the selection of resistant HIV strains. Unintentional reasons for missing doses were most commonly reported. An ability to describe the intended effect of antiretroviral therapy on HIV viral load was the best predictor of adherence. This finding is consistent with other research suggesting that adherence is associated with an understanding and belief in the effectiveness of antiretroviral therapy.
