RESUMO
BACKGROUND: The aim of this review was to investigate the impact of short message service (SMS)-based interventions on childhood and adolescent vaccine coverage and timeliness. METHODS: A pre-defined search strategy was used to identify all relevant publications up until July 2022 from electronic databases. Reports of randomised trials written in English and involving children and adolescents less than 18 years old were included. The review was conducted in accordance with PRISMA guidelines. RESULTS: Thirty randomised trials were identified. Most trials were conducted in high-income countries. There was marked heterogeneity between studies. SMS-based interventions were associated with small to moderate improvements in vaccine coverage and timeliness compared to no SMS reminder. Reminders with embedded education or which were combined with monetary incentives performed better than simple reminders in some settings. CONCLUSION: Some SMS-based interventions appear effective for improving child vaccine coverage and timeliness in some settings. Future studies should focus on identifying which features of SMS-based strategies, including the message content and timing, are determinants of effectiveness.

INTRODUCTION: This exploratory study aimed to assess contact dermatitis (CD) risk among workers using the Manitoba Occupational Disease Surveillance System (MODSS). METHODS: The MODSS linked accepted time-loss claims from the Workers' Compensation Board of Manitoba (2006-2019), with administrative health data from medical and hospital records (1996-2020). CD risk by occupation and industry (hazard ratio, 95% confidence intervals) was estimated using Cox proportional hazard models, adjusted for age and stratified by sex. RESULTS: Increased risk of new onset CD was observed among some occupations and industries with known skin irritants and allergens. Some occupations with known increased risks of CD remained elevated when removing the accepted WCB cases was performed, suggesting that all CD cases in these occupations may not show up in WCB statistics. Increased risk was also observed for occupations and industries with unknown exposures related to CD, whereas some groups known to be at risk of CD were not observed to have elevated risks in this cohort. DISCUSSION: The MODSS successfully identified some occupations and industries known to be at high risk of occupational CD, but not others. Some occupations not typically associated with work-related CD were also identified, which warrants further investigation.
