Healthcare and technology go hand in hand, but the benefits of technology-enhanced healthcare services have not yet percolated to the rural and remote areas of India. iKure Techsoft, a medical research technology company, is trying to bridge this gap.
iKure Techsoft, in partnership with Aegle Angels Foundation, is setting up intelligent health kiosks in rural areas where healthcare infrastructure is negligent. So rural masses need not travel to far away diagnostic centres for regular check-ups. So far, the company has installed 15 such kiosks in rural parts of West Bengal.
How the kiosks work
Every kiosk has a rural medical practitioner (RMP) who takes patients’ blood pressure, blood sugar, body temperature, ECG (electrocardiogram), weight, height and pulse readings with commonly used medical instruments. On the face of it, it looks like a conventional dispensary, but what makes these facilities unique is the technology that powers these kiosks.
The kiosks are equipped with many interesting and innovative pieces of technology, the most innovative being a handheld device called WHIMS—the wireless health incident monitoring system. It can capture data from a maximum of 16 medical instruments or 16 patients at the same time. The device has been configured to enable automatic digital transmission of data through Zigbee—a wireless protocol. After WHIMS reads measurements from these instruments, Zigbee automatically transmits all the collected information to a data server, wirelessly. This information (test reports) is stored in the server as the patient’s medical history for future reference, explains Sujay Santra, founder-director, iKure Techsoft.
Based on the test results, the RMP can prescribe medicines. The RMPs are medical practitioners trained and appointed by iKure. They manually enter the analysis and prescription, which is then stored in the server. Medical history records of patients are also stored for future use.
Enabling healthcare remotely
For complex cases, the RMP may require to consult a doctor. To deal with such situations, iKure has tied up with The Mission hospital and Jubilant Kalpataru hospital, both of which are located in West Bengal. At these hospitals, a team of about eight doctors remotely attends to the cases referred by the RMPs.
If required, the RMP can also consult a specialist stationed at these hospitals via a phone after transmitting the patient’s details. The specialist can access the patient’s details directly from the server. If the patient requires special advice on a complicated case, he is referred to the nearest hospital available. In this case, the medical history of the patient along with the line of treatment prescribed by the RMP at the health kiosk (if any) is wirelessly sent to the server. This data can be accessed by the specialist at the hospital through a laptop or mobile phone.
Patients from rural areas usually do not remember details of their medical history and are unaware of medication they have taken. “Having test results and prescriptions (stored on the server) transmitted to specialists in the hospital (where the patient’s case is referred) helps reduce consultation time with the new doctor,” says Santra.
The doctor usually reverts to the RMP with any of four messages: ‘Nothing to worry,’ ‘Change the drug,’ ‘Change dosage’ or ‘Bring patient to the hospital’.
Another feature that makes iKure kiosks stand out is their ability to alert doctors in the case of an emergency. This is done through an application programming interface (API) called ‘Rules Engine,’ which makes the kiosks intelligent enough to figure out when a patient requires immediate attention and alert a doctor.
The Rules Engine sits in the server and analyses every piece of new data that is fed into the database. It processes the data and compares it with the data already stored. If the data is within the normal limits, it considers the case to be worthy of escalation. If the patient’s reading crosses this limit, an alert SMS is sent to a registered number assigned to the pool of doctors who are part of this service. The available doctor can then log on to the server using his mobile phone or computer and connect with the practitioner stationed at the kiosk.
Key technological hurdles
Developing such a system was not without challenges. Santra enumerates the key ones: “Many medical instruments available in the market output data in the analogue format. There were many hiccups at the stage of configuring instruments with WHIMS. Every medical equipment used for measuring data—digital or analogue—behaves differently. We took up the challenge and cracked how the data can be captured, processed and transmitted. Every instrument had to be configured to enable automatic digital transmission of data through Zigbee, Wi-Fi or any other available network.”
Another challenge related to transmission of ECG reports as data volume is huge for these reports. Santra tells how this was overcome: “To transmit such reports we optimise the data and send minimal information. A technique based on AZTEC technology is used for optimisation and compression of ECG signals. This enables the data to be sent through a 330-character-long SMS. iKure owns a patent for this technology.”
iKure also holds patents for the position detection technique used to tap data from a mercury sphygmomanometer (aka blood pressure meter) by using the metallic property of mercury, WHIMS and Rules Engine.
