Summary
Adverse drug effects (ADE) were studied in primary care patients, revealing specific frequencies and patient demographics. Primary care settings are valuable for pharmacosurveillance research.
Area of Science:
- Pharmacovigilance
- Clinical Pharmacology
- Primary Care Medicine
Context:
- A descriptive, longitudinal study conducted in 1990 at an urban health center in Madrid, Spain.
- Involved 15,483 patients, nine general practitioners, and one pharmacist.
- Physicians documented adverse drug effects (ADE) observed in patients, reporting details on medications, clinical manifestations, and outcomes.
Purpose:
- To characterize the incidence and nature of adverse drug effects (ADE) within a primary care population.
- To identify patient demographics and drug classes most frequently associated with ADE.
- To assess the utility of primary care settings for pharmacosurveillance.
Summary:
- A total of 326 adverse drug effects (ADE) were reported, translating to 30.9 ADE per 1,000 patients.
- 117 active pharmaceutical ingredients were implicated, with 415 clinical manifestations recorded.
- Women and specific age groups (infants under one year, elderly) exhibited higher relative frequencies of ADE.
Impact:
- Highlights discrepancies between absolute and relative frequencies of ADE when considering prescription units.
- Identifies novel ADE not previously documented in existing literature.
- Underscores the significant role of primary care in ongoing pharmacosurveillance and drug safety research.
