Chronic care management is the care of a long-lasting illness, such as diabetes or high blood pressure, in the months between visits to the doctor, together with the apps, coaches and sensors that help with it. A chronic condition is an illness that lasts for years. It is managed every day rather than cured in one visit.
Picture a 45-year-old bank manager in Nagpur with type 2 diabetes. The doctor sees the manager for ten minutes, once every three months. The other 90 days decide how the illness goes: what the manager eats, how much the manager walks, and whether the medicine is taken on time. The doctor sees none of this. At the next visit, the doctor has one blood test, the HbA1c, which shows the average blood sugar of the last three months.
Software now helps during those 90 days in two ways, shown here as two zones.
The first zone is digital therapeutics: programmes that pair an app with a coach, a device and sometimes a doctor. In India, a CGM-based diabetes reversal programme shows a person what each meal does to their blood sugar, and a coach suggests changes. A digital diabetes management app reads blood sugar and blood pressure and suggests the next step. Other programmes treat back pain through digital physiotherapy, or treat stress and anxiety. In the United States, employers and health insurers pay for many of these programmes. They expect to spend less later on hospital stays and operations.
The second zone is wearable health monitoring: the devices that measure the body outside the clinic. A continuous glucose monitor (CGM) on the arm reads blood sugar every few minutes. A personal ECG monitor records the heart's rhythm through the fingers. A patch keeps watching a patient who has been sent home from hospital. Each device sends its readings over the internet to software, and the software alerts a doctor when a reading matters. This way of working is called remote patient monitoring.
The devices produce far more readings than any doctor can look at. A glucose sensor alone records about 288 readings a day. So, more and more, an AI model reads the signal first and flags what needs a person's attention. In India, an AI model and a heart specialist together read ECGs sent from small clinics, through remote ECG interpretation. When software diagnoses or treats in this way, regulators treat it as a medical device. This is called software as a medical device (SaMD).
India needs this software more than most countries. It has more people with diabetes than almost any other country, and few diabetes specialists, especially outside the big cities. With these tools, the bank manager in Nagpur is no longer alone between visits. A sensor shows the blood sugar, an app records the day, and a coach helps the manager change daily habits.
