Which of the following is included in passive monitoring of drug effectiveness?

Passive monitoring of drug effectiveness involves strategies where the healthcare provider relies on the patient to indicate the effectiveness of a treatment rather than actively collecting data through tests or constant assessment. In this context, instructing the patient to report if the drug is not effective aligns with passive monitoring. It encourages the patient to engage in their own care by providing feedback on their response to the medication.

This method places importance on the patient's subjective experience, making it a practical approach in routine practice, especially when active measures are not feasible. In contrast, therapeutic drug levels and frequent laboratory tests are proactive strategies that require healthcare providers to gather and analyze specific data to monitor the medication's effectiveness and safety. Similarly, patient satisfaction surveys, while valuable, typically assess the overall experience with care rather than focusing specifically on the effectiveness of a particular drug. Therefore, they do not fit into the category of passive monitoring as closely as the patient reporting their own experiences with the medication.
