During the patient visit, which method is encouraged to help track medication adherence?

Tracking medication adherence is crucial for effective patient care, and assessing remaining dosage units directly reflects a patient's medication use. By counting the number of pills left in a patient's prescription bottle or similar containers, healthcare professionals can gain insight into whether the patient is taking the medication as directed. This method enables a tangible measure of adherence, offering a clear indication of whether the patient is following their prescribed regimen.

In contrast, reviewing patient online prescriptions may provide some information about the patient's ongoing treatments but does not give data about actual usage. Measuring blood pressure is relevant for monitoring a patient's health condition but does not specifically address adherence. Collecting patient symptom history may serve to evaluate the effectiveness of therapy but does not provide direct evidence regarding whether the patient is taking their medication as prescribed. Therefore, assessing remaining dosage units stands out as the most effective method for tracking medication adherence in this scenario.
