To efficiently share clinical information, regional healthcare networks have been developed nationwide. As per a survey, only 1% of the population is registered in such networks. Unless residents in each region become aware of the service, they would not willingly register themselves to share their clinical data. Accordingly, this study administered an online questionnaire to measure their recognition on the networks and their attitude toward online-sharing of clinical information.
The surveillance showed that the recognition rate was 17.8% and the approval rate was 63.3%, as national average. The results indicated a positive correlation between the recognition and the approval rate, a weak correlation between the number of networks and the recognition in a prefecture, and no correlation between the number of networks and the approval rates. The results suggested that promotion campaigns of the networks might contribute to the online sharing of patient information.
