Background: Nasopharyngeal aspiration (NPA) is used widely in the collection of nasal specimens for respiratory virus diagnosis. The method has limitations in relation to technical expertise, patient anxiety, and apparatus dependence. Nasal washing (NW) offers an alternative approach. Objective: To identify the merits of two different NW methods in comparison with NPA. Design: Two hundred children with acute respiratory infection (ARI) were randomised to receive one of three collection devices: (i) standard NPA, (ii) NW using a 30ml earsyringe bulb (NWb), or (iii) NW using a 5ml syringe (NWs) with a shortened (9cm) 8FG tube. Assessment focused on ease of procedure, acceptability to parent and child, and adequacy of epithelial cell yield for immunofluorescence testing. A short questionnaire was delivered.
21 109 METHODS 110 Adaptation of WASH FIT to WASH FAST 111 The adaptation of WASH FIT to WASH FAST entailed four main steps: (1) developing a numeric scoring 112 system and a system for meaningful aggregation of scores, to enable comparison across HCFs and 113 facilitate tracking of WASH services over time;(2) modifying the facility assessment -so that indicators
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
