Propeller calculates adherence based on a patient’s daily schedule. If a patient is supposed to take 2 doses a day, but has only been taking one dose per day for the past week, their weekly adherence would be 50%, or 7/14.
Propeller considers night-time to be 10:00 PM – 6:59 AM, localised to the patient’s time zone. Any usages from a patient’s reliever inhaler in this time period will be considered a night-time event.
Propeller also breaks down reliever usages at other times of the day into groupings to help spot trends in a patient’s reliever usage. Here’s how we break down the times of the day, always localised to the patient’s time zone:
- Morning: 7:00AM – 11:59AM
- Afternoon: 12:00PM – 4:59PM
- Evening: 5:00PM – 9:59PM
- Night: 10:00PM – 6:59AM
The COPD baseline looks at the patient’s reliever usage history and creates an average of the number of reliever usages in the recent past. That baseline then gets compared to the number of usages a patient had over the last 48 hours to show if they’re above or below that baseline.
If a patient has used their reliever inhaler 10 times in a day, or if they have a reliever use above their baseline for a series of 2 days, Propeller will trigger an Exacerbation Risk Alert for that patient.
Propeller uses (USA-based) NHLBI guidelines and a patient’s reliever usages to calculate the asthma control score. For specifics on each score, see this article:
Propeller is compatible with most Metered Dose, Soft Mist and Dry Powder Inhalers. See our Compatible Medications List here:
This is the date of the last notification that was resolved by a care team member.
When patients manually enter an event into our system using the app and not their sensor, we will record that event as having required 0 puffs. Typically this is used by patients who have medications that are not supported by Propeller sensors.
When you identify patients with poor adherence and increased reliever medication use, this would indicate a need for medication education regarding the patient’s daily preventer medication. This is a great opportunity to stress why compliance is important and how preventer medications work to help prevent the need for reliever med use.
When we identify patients that have good adherence and increased reliever med use, this would indicate a change in the patient’s level of control. It would be important to communicate with this patient to determine if this was an acute issue or the potential need for a step up in their medication therapy.
Are there times I should contact patients when they don’t have an alert? How do you identify those patients?
With the Propeller platform, we now are able to view the number of puffs a patient takes from each inhaler. This can be seen within the Patient Detail of the patient’s account by clicking on their name from the My Patients list. We can identify those patients that may not be taking their prescribed dose of their preventer inhaler. We also have insight into the number of puffs a patient may be taking from their reliever inhaler. This is another great opportunity for patient education.
