Patient-reported medication symptoms in primary care

Area of Science:

• Pharmacovigilance
• Primary Care Medicine
• Patient Safety

Background:

• Prevalence and characteristics of medication-related symptoms in primary care are poorly understood.
• The relationship between these symptoms, adverse drug events (ADEs), and patient-physician communication is unclear.
• Factors influencing patient-physician dialogue about medication side effects require further investigation.

Purpose of the Study:

• To determine the prevalence and nature of medication-related symptoms in primary care.
• To examine the association between these symptoms and adverse drug events (ADEs).
• To identify factors affecting patient-physician communication regarding medication symptoms and subsequent therapy modifications.

Main Methods:

• A study involving 661 patients from 4 adult primary care practices.
• Patient interviews conducted 2 weeks and 3 months post-visit, alongside medical record reviews.
• Physician surveys and expert review to confirm ADEs; multivariable regression analysis to identify associated factors.

Main Results:

• 179 patients reported 286 medication symptoms, discussing 196 (69%) with physicians.
• Physicians altered therapy for 76% of discussed symptoms; failure to discuss led to 23 ADEs.
• Patients taking more medications and those with multiple allergies were more likely to discuss symptoms; male physicians and those at specific practices were more likely to change therapy.

Conclusions:

• Primary care physicians can potentially mitigate ADEs by actively inquiring about and addressing patient-reported medication symptoms.
• Improving patient-physician communication regarding medication side effects is crucial for enhancing patient safety.
• Addressing medication symptoms proactively may reduce the duration and severity of adverse drug events in primary care settings.
