The impact of self-reported Second Hand Smoke exposure on asthma severity and hospital length of stay in a state-wide pediatric inpatient asthmatic population

Abstract Details

2018, MS, University of Cincinnati, Medicine: Epidemiology (Environmental Health).
Objective: To determine the relationship between second hand smoke (SHS) exposure and asthma severity, and the impact of SHS exposure on participant hospital length of stay (LOS). Background: Exposure to SHS is a known cause of asthma exacerbations in children. However, there is little published data about the level of relationship between SHS exposure and baseline asthma severity and whether the amount of SHS exposure per day has an impact on length-of-stay (LOS) in an inpatient population. Methods: Participant and family medical history and environmental exposure data were obtained through a self-reported questionnaire. Treatment information and hospital length-of-stay data were obtained through medical chart review after the participant was discharged from the hospital. Results: 1012 children were enrolled in the study across six hospitals. Average age was 6.6 ± 4 years, 612 (60.5%) participants were male, and 476 (47.04%) were Black or African American. 511 (50.49%) had a baseline asthma severity of intermittent or mild persistent asthma, 519 (51.38%) had a LOS > 24 hours, and 466 (46.05%) had self-reported exposure to second hand smoke (SHS). Increased SHS exposure was significantly related to a higher level of baseline asthma severity after adjusting for site variance and covariates (p=0.0090). SHS exposure was not significantly related to LOS in a separate model (p=0.1091), which found continuous albuterol administration significantly related to increased LOS (p<0.0001). Post hoc analysis showed a significant relationship between increased SHS exposure and increased continuous albuterol administration (p=0.0381). Conclusions: Increased SHS exposure is related to an increase in asthma severity. Increased SHS exposure is not related to increased LOS. However, further analysis revealed that increased SHS exposure is associated with increased use of continuous albuterol, which in turn is related to a longer LOS. This suggests SHS exposure has a role to play in longer LOS.
