Needs analysis and development of a tailored mobile message program linked with electronic health records for weight reduction

• Participants had different lifestyles with different metabolic profiles.
• Participants desired personalized nutritional guide for weight reduction.
• This was the first feasibility study using text messaging linked with EHRs.
• Text messaging linked with EHRs and lifestyle showed high satisfaction score.

ObjectiveWe developed and pilot-tested a personalized text messaging service program based on data from electronic health records (EHRs) and lifestyle questionnaires for weight control.MethodsIn the health promotion center of a hospital, 340 participants with a body mass index (BMI) greater than 25 were recruited and surveyed for the development of a text messaging program. After developing the interface linking the EHRs with personalized text messages for weight loss, we pilot-tested this program in 102 participants for its feasibility, acceptability and satisfaction.ResultsAccording to the needs analysis, the participants desired additional information about personalized nutrition and exercise. We selected many variables from the EHRs and questionnaires to create text messages with a more personalized program. After a 1-month trial of the text messaging program, the participants’ satisfaction score was 7.9 ± 1.5 and recommendation score was 7.5 ± 1.8.ConclusionsA personalized short message service (SMS) linked with EHRs was feasible, and the pilot test showed high satisfaction and recommendation scores. Further evaluation using a well-designed trial will be needed.
