Asthma and COPD
- Evolution of:
The design of inhalers has continued to change over time. From large disks to meter dose pumps, efforts have been made to increase adherence to inhalers by simplifying how it is used. Counters were also added to inhalers to inform patients how many pumps they have remaining in their devices. The counters also allowed the provider to determine how many times the inhaler was used if the device was brought into the office. Outside of these counters providers had to rely on the patient’s recollection of the frequency in which they used the inhaler. This subjective data did not allow for real-time analytics or the formulation of a care management plan based on concrete data. If physicians are not made aware of the improper use of inhalers or lack of use, hospital utilization rates for exacerbations would be difficult to reduce.
Recently the Propeller sensor was approved for use with symbicort and now works with over 90% of inhaled medications. This device attaches to a meter dose inhaler. When a patient uses the inhaler by pushing in the canister, the sensor logs this information into a mobile app. The information can be shared with the patient’s physician to identify the frequency of use, time of use, and possible triggers such as pollen or smoke.
The more data physicians collect on inhaler usage, the better they can work with the patient to develop a care plan for their respiratory condition. The Propeller sensor also records the day and time patients use their inhaler and if the smart device does not receive any information the patient receives a reminder. Improving adherence and reducing hospitalizations are potential outcomes of real-time analytics with such innovative technology.
