Aim: We surveyed whether clinicians used the WhatsApp messaging application to view neonatal chest radiographs and asked a sub-sample to compare them with computer screen viewings.
Methods: The study was conducted at three university-affiliated medical centres in Israel from June-December 2016. Questionnaires on using smartphones for professional purposes were completed by 68/71 paediatric residents and 20/28 neonatologists. In addition, 11 neonatologists viewed 20 chest radiographs on a computer screen followed by a smartphone and 10 viewed the same radiographs in the opposite order, separated by a washout period of 2 months. After another 2 months, five from each group viewed the same radiographs on a computer screen. Different interpretations between viewing modes were assessed.
Results: Most respondents used WhatsApp to send chest radiographs for consultation: 82% of the paediatric residents and 80% of the neonatologists. The mean number of inconsistencies in diagnosis was 3.7/20 between two computer views and 2.9/20 between computer and smartphone views (p = 0.88) and the disease severity means were 3.7/20 and 2.85/20, respectively (p = 0.94). Neonatologists using WhatsApp only determined umbilical line placement in 80% of cases.
Conclusion: WhatsApp was reliable for preliminary interpretation of neonatal chest radiographs, but caution was needed when assessing umbilical lines.
