Many people have their health care costs covered by insurance (either private or government insurance). These insurance programs need to manage their expenses while providing adequate care to the patient. One of the biggest challenges to healthcare providers and insurance companies is patients who do not faithfully observe their prescribed treatments. Sometimes patients will even lie to their doctors because they want to appear compliant even if they are not. All of this can lead to later misdiagnosis and wasted treatment and often complications that are usually more expensive to treat. (Consider the case of new strains of antibiotic resistant bacteria, like tuberculosis. These exist specifically because patients did not complete their course of antibiotics as prescribed. Now, these strains pose a very serious public health risk, which is something that could have been avoided.)
One of the most common therapeutic prescriptions that patients do not follow faithfully is to take their pills, on schedule and as directed. In cases where compliance is very important, patients will be asked to go to a clinic to be observed taking their pills each time they need to take one. You can imagine how inconvenient this can be for the patient, and how expensive this can be for the insurance company as they try to save money in the long run.
New Solutions Enabled by Semiconductor Technology
A new solution based on a pill with an embedded RF transmitter and a monitoring patch aims to make it easier to manage prescription medications. With this solution, a transmitter embedded in the pills sends out an RF signal when it is digested by stomach acid. This signal is picked up by a patch that is worn like a band-aid on the patient. Additional electronics in the patch send the information on pill ingestion to a smartphone. From there, the data can either be uploaded to a datacenter or a doctor’s office, providing the required evidence that the patient took the pill as prescribed.
Ensuring Widespread Adoption
The specialized chips inside the pills need to be extremely small so they pass through the GI tract without any discomfort to the patient. The chips also needed to be guaranteed to be safe to ingest. They also must require very little power so that they can work without a traditional battery, while still producing an RF signal strong enough to reach the patch. It is incredibly important that the design is not in any way inconvenient to the patients so that they don’t object to using it, which might pose a serious barrier to widespread adoption.
This new solution is more efficient and less expensive for the insurance company and the healthcare system as a whole. At the same time, it will improve overall patient experience and outcomes. Widespread adoption of such a prescription-compliance solution holds the potential to improve public health. The new technology also demonstrates how semiconductors for medical applications and the benefits they bring are proliferating beyond PCBs and traditional electronic machines.
