The main objective of our study was to investigate the impact of individually tailored short text messages on the rate of psychiatric hospital readmissions, health care service use, and clinical outcomes. In addition, we analyzed treatment costs.

From the Wall Street Journal summary: A recent study has found evidence suggesting text messages could reduce one’s odds of a second heart attack. A six-month clinical trial in Australia found that patients recovering from a heart attack were more likely to maintain lower blood pressure, less body fat and lower cholesterol levels than a control group when the patients received text messages asking and giving suggestions about their health routines. Patients receiving the texts also were more likely to be active and to quit smoking than the patients in the control group, who didn't receive such texts.

mFHAST Implication: Opportunity to use short message service (SMS) as reminder messages to boost treatment adherence to RDT.

From the summary article: Mobile devices have increasingly penetrated our life and have become one of the study subjects in clinical informatics. Well-designed randomized trials are rarely used for these studies. A recent publication in the telemedicine journal and e-health tested the utility of Fitbit, a wearable device, in comparison with SMS messaging in prompting overweight and obese adults to increase their physical activity [5]. Sixty-seven adults enrolled in the study. The results suggest that a Fitbit and SMS mixed approach achieves a small increase in moderate- to vigorous-intensity physical activity at a 6-week follow-up, and SMS reminders are insufficient in increasing physical activity beyond 1 week.

BACKGROUND:
Diabetic foot neuropathy (DFN) is one of the most important complications of diabetes mellitus; its early diagnosis and intervention can prevent foot ulcers and the need for amputation. Thermometry, measuring the temperature of the feet, is a promising emerging modality for diabetic foot ulcer prevention. However, patient compliance with at-home monitoring is concerning. Delivering messages to remind patients to perform thermometry and foot care might be helpful to guarantee regular foot monitoring. This trial was designed to compare the incidence of diabetic foot ulcers (DFUs) between participants who receive thermometry alone and those who receive thermometry as well as mHealth (SMS and voice messaging) over a year-long study period.
METHODS/DESIGN:
This is an evaluator-blinded, randomized, 12-month trial. Individuals with a diagnosis of type 2 diabetes mellitus, aged between 18-80 years, having a present dorsalis pedis pulse in both feet, are in risk group 2 or 3 using the diabetic foot risk classification system (as specified by the International Working Group on the Diabetic Foot), have an operating cell phone or a caregiver with an operating cell phone, and have the ability to provide informed consent will be eligible to participate in the study. Recruitment will be performed in diabetes outpatient clinics at two Ministry of Health tertiary hospitals in Lima, Peru.
INTERVENTIONS:
participants in both groups will receive education about foot care at the beginning of the study and they will be provided with a thermometry device (TempStat™). TempStat™ is a tool that captures a thermal image of the feet, which, depending on the temperature of the feet, shows different colors. In this study, if a participant notes a single yellow image or variance between one foot and the contralateral foot, they will be prompted to notify a nurse to evaluate their activity within the previous 2 weeks and make appropriate recommendations. In addition to thermometry, participants in the intervention arm will receive an mHealth component in the form of SMS and voice messages as reminders to use the thermometry device, and instructions to promote foot care.
