a patient fills a 90 day prescription one in 6 months. what is the adherence percentage for his patient. how to I work this question

The adherence percentage for this patient can be calculated as follows:

- The patient fills a 90-day prescription once in 6 months, which means he/she is taking the medication for 90 days every 6 months.
- There are 180 days in 6 months, so the patient should be taking the medication for half of those days (i.e., 90 days).
- Therefore, the adherence percentage for this patient is:

(adherence days / total days) x 100

= (90 / 180) x 100

= 50%

So, the patient's adherence percentage is 50%, which means he/she is taking the medication as prescribed for only half of the days in the 6-month period.
