Healthcare interventions enable healthcare providers to monitor vital parameters of their patients and instruct them to make changes in their daily routine to ensure a healthy life. Mobile phones and cloud computing offer new opportunities to improve the technologies used for healthcare interventions. We propose a system (MHealthInt ) that focuses on healthcare intervention and utilizes the existing features of a smart phone to make the intervention process more efficient. We use Google Cloud Messaging (GCM) to deliver the intervention. We automate the intervention process, wherein a provider can schedule the intervention messages at any time of the day/week across intervention and control groups. We conducted a feasibility study involving providers and have documented the results. The study lasted a week and was found to be an improvement over a previous study that was conducted using SMS/text messages.
