Indoor air modification interventions for prolonged non-specific cough in children

Abstract

Background: Non-specific cough has been defined as non-productive cough in the absence of identifiable respiratory disease or known aetiology and is common in childhood. These children are treated with a variety of therapies, including non-pharmacological treatments. There is a wide variety and a growing market for these non-pharmacological treatments that include air-modification modalities. Objectives: To determine the efficacy of air-modification modalities, (ionisers, vaporisers, humidifiers, air filters, regular vacuuming), in treating children with non-specific cough. Search methods: The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, OLDMEDLINE and EMBASE databases were searched by the Cochrane Airways Group. The latest searches were performed in November 2008. Selection criteria: All randomised controlled trials comparing air-modification modalities with a placebo treatment, for any duration. Data collection and analysis: Results of searches were reviewed against pre-determined criteria for inclusion. Five papers were considered for inclusion but no eligible trials were identified and thus no data was available for analysis. Main results: No randomised controlled trials that examined the efficacy of air-modification modalities in the management of prolonged, non-specific cough in children were found. Authors' conclusions: Based on the evidence currently available, a recommendation can not be given for air-modification interventions in the treatment of prolonged, non-specific cough in children.
