Area of Science:

  • Nursing Education
  • Patient Safety
  • Healthcare Quality Improvement

Background:

  • Medication calculation errors pose a significant risk in healthcare settings, potentially disrupting patient treatment protocols.
  • Accurate medication calculation is a critical skill for registered nurses (RNs).

Purpose of the Study:

  • To evaluate the effectiveness of different educational interventions on improving RNs' medication calculation skills.
  • To compare the cost-effectiveness and nurse satisfaction levels of various training methods.

Main Methods:

  • An experimental study with a pretest-posttest, control group design involving 67 RNs from three healthcare agencies.
  • Nurses completed a 20-item medication calculation test and a demographic/attitudinal questionnaire.
  • Nurses were randomly assigned to three experimental groups (3-hour interventions) or a control group, with posttesting 4-5 months later.

Main Results:

  • All groups, except the self-study workbook group, showed score improvements. No significant differences in posttest scores were found between experimental and control groups.
  • The classroom intervention was the most expensive, while the workbook was the least costly.
  • Nurses reported the workbook as most satisfying and computer-assisted instruction (CAI) as least satisfying.

Conclusions:

  • No single intervention method demonstrated a statistically significant advantage in improving medication calculation test scores.
  • Cost and nurse satisfaction varied considerably among the tested interventions.
  • Staff development educators must focus on enhancing the effectiveness of medication calculation training for RNs.
