# MobiDabet: Mobile Telemonitoring System for Patients with Type 2 Diabetes Mellitus (T2 DM)
## 2 Materials and Methods  
Follow-up of patients with T2 DM at the Mexican Social Security Institute (IMSS) occurs following the official Mexican standard NOM-015-SSA2-2018 focused on prevention, detection, diagnosis, treatment, and control of diabetes mellitus [4]. The treatment plan includes the setting of aims adapted to the characteristics of the patient, non-pharmacological management, pharmacological treatment, education, and awareness of patients about their condition, self-monitoring, prevention, and early detection/palliation of complications. The main goals of T2 DM treatment are to relieve symptoms, prevent acute and chronic complications, improve quality of life, and reduce mortality from this disease or its complications. Treatment must be tailored to the specific characteristics and needs of the patient. Therefore, the patients'initial treatment includes non-pharmacological and pharmacological measures, food plans, education, and awareness of patients about their condition, weight control, and physical activity, among others [4]. The health personnel who care for the patients are general physicians/family doctors and nutritionists (see Figure 1). The general physician is responsible for assigning a treatment plan for the patient. The treatment plan must be tailored to the specific characteristics and needs of the patient. To follow-up on this plan, the general physician reviews, in each consultation, the laboratory results and a booklet with the results recorded by the patient of the different glucose tests applied daily. The frequency of medical consultations depends on the compliance level with the goals established in the treatment and clinical evolution. Metabolic control and identification of possible health complications are done during the medical consultations with the general physician, as well as other activities such as the record of the patient's weight, record of his blood pressure, and strength of his education. Each patient requires laboratory studies at least once a year; these studies include blood chemistry test, general urine test, thyroid profile test, complete blood count, among others. On the other hand, the nutritionist is responsible for establishing food plans. To achieve this, the nutritionist analyzes and considers the patient's habits to make relevant recommendations that contribute to achieving treatment goals. Therefore, patients need to input the type and frequency of eating specific foods. In consultations with the nutritionist, the appropriate diet is indicated according to the patient's ideal weight's caloric requirements. In this regard, the anthropometry record (body measurements) is performed to help in the diet assignation. Visits with the nutritionist are usually monthly (see Figure 1). Patients with T2 DM can live without acute and chronic complications by adopting a treatment tailored to their specific characteristics and needs that involves non-pharmacological management, pharmacological treatment, education, and awareness of patients about their condition, self-monitoring, prevention, early detection/palliation of complications, and continuous control with specialists. Therefore, our system's analysis and design are based on the current monitoring and control process carried out in the IMSS for patients with this chronic disease, which aligns with the official Mexican standard NOM-015-SSA2-2018. To prove the system usability, tests were carried out under fictitious cases, and then the field study was carried out by means of the selection, for convenience, of a sample obtained from the population of patients with T2 DM, with the approval of the Local Committee for Health Research (Research Ethics Committee) of the LANIA (Project identification code: 2016412-2016755-IIDIABETES) and the signing of informed consent by participants.

In this regard, different diagrams are used for a better understanding of the modeling.
