RESUMO
INTRODUCTION: This work aimed to analyze whether breastfeeding is a predictive factor for admission to ICU or needing mechanical ventilation in children under 6 months with RSV+ respiratory infection. METHODS: A retrospective cohort study was performed in three hospitals. Binary and multiple logistic regression analyses were performed to evaluate the association of variables with admission to the ICU or receiving mechanical ventilation. RESULTS: We analyzed 414 admissions, of which 293 (70.8%) had received breastfeeding, 43 (8.1%) were admitted to the ICU, and 26 (5.4%) required mechanical ventilation. Bivariate analysis showed that breastfeeding for at least 15 days and a longer duration of breastfeeding were associated with a lower risk of admission to the ICU and requiring mechanical ventilation. Multivariate analysis showed that not having been breastfed for at least 1 month was predictive of ICU admission; not having been breastfed for at least 2 months was predictive of needing mechanical ventilation. CONCLUSIONS: Breastfeeding for as little as 15-28 days could be associated with a lower risk of ICU admission and requiring mechanical ventilation in infants younger than 6 months admitted for RSV+ bronchiolitis. Since breastfeeding is one of the few protective factors that can be promoted, this finding is relevant for current clinical practice and the development of health promotion programs. Future studies can compare their results to ours.
RESUMO
BACKGROUND: We previously demonstrated that a hand hygiene program, including hand sanitizer and educational measures, for day care center (DCC) staff, children, and parents was more effective than a soap-and-water program, with initial observation, in preventing respiratory infections (RIs) in children attending DCCs. We analyzed the cost-effectiveness of these programs in preventing RIs. METHODS: A cluster, randomized, controlled and open study of 911 children aged 0 to 3 years, attending 24 DCCs in Almeria. Two intervention groups of DCC-families performed educational measures and hand hygiene, one with soap-and-water (SWG) and another with hand sanitizer (HSG). The control group (CG) followed usual hand-washing procedures. RI episodes, including symptoms, treatments, medical contacts, complementary analyses, and DCC absenteeism days, were reported by parents. A Bayesian cost-effectiveness model was developed. RESULTS: There were 5201 RI episodes registered. The adjusted mean societal costs of RIs per child per study period were CG: 522.25 (95% confidence interval [CI]: 437.10 to 622.46); HSG: 374.53 (95% CI: 314.90 to 443.07); SWG: 494.51 (95% CI: 419.21 to 585.27). The indirect costs constituted between 35.7% to 43.6% of the total costs. Children belonging to the HSG had an average of 1.39 fewer RI episodes than the CG and 0.93 less than the SWG. It represents a saving of societal cost mean per child per study period of 147.72 and 119.15, respectively. The HSG intervention was dominant versus SWG and CG. CONCLUSIONS: Hand hygiene programs that include hand sanitizer and educational measures for DCC staff, children, and parents are more effective and cost less than a program with soap and water and initial observation in children attending DCCs.
