Summary

Diuretic prescription knowledge is poor among elderly patients, with a significant portion unable to recall correct indications. This highlights a critical gap in patient education regarding diuretic medications.

Area of Science:

  • Geriatrics
  • Pharmacology
  • Internal Medicine

Background:

  • Diuretics are commonly prescribed, particularly for elderly patients.
  • Understanding of medication indications is crucial for patient adherence and outcomes.
  • Previous research has not fully elucidated patient knowledge regarding diuretic prescriptions.

Purpose of the Study:

  • To assess the prevalence of diuretic use in hospitalized patients.
  • To evaluate patient knowledge of diuretic indications.
  • To identify factors associated with poor understanding of diuretic prescriptions.

Main Methods:

  • A cross-sectional study involving 203 general medical ward admissions.
  • Patient interviews and data collection from general practitioners and hospital doctors.

  • Assessment of patient knowledge regarding drug indications and doses.

    • Main Results:

    • Diuretic use was prevalent in 31% of patients.
    • Patients incorrectly recalled the indication for 31% of prescribed diuretics, significantly higher than for other drugs (16%).
    • Older age, lower Abbreviated Mental Test (AMT) scores, and higher drug polypharmacy were associated with diuretic use and poorer knowledge.

    Conclusions:

    • A significant proportion of patients, especially older individuals with cognitive impairment, exhibit poor knowledge of diuretic indications.
    • While age and cognitive status contribute, other factors likely influence this knowledge gap.
    • Improved patient education strategies are needed to enhance understanding of diuretic therapy.
