Development of a comprehensive medical recorder on a cellphone

Paper medical diaries have effectively been used in chronic diseases for self-management without information and communication technology for many cases. To facilitate self-control in chronic diseases, and observe one's own condition objectively and continuously, we developed a cellphone-based medical recorder (MedData) for patients with chronic diseases. The MedData is based on the Java2 Micro Edition and DoJa-3.5 (NTT DoCoMo, Inc.), and it runs like a scheduler with a calendar, diary, and data entry canvas. The MedData stores laboratory data, such as blood pressure, BUN (blood urea nitrogen), creatinine, Hb A1c (glycosylated hemoglobin), and other pertinent comments, into a cellphone memory. Detailed graphic displays of the data are automatically visualized. The MedData can customize recording events, items, prescriptions, and graphics all on the cellphone. These can then be transferred via an infrared port between a cellphone and a PC.
