High workload in pharmacies increases job stress and reduces dispensing accuracy. Increased workload modestly decreased error detection, particularly for data-entry mistakes, but did not significantly impact mood or perceived workload.

Area of Science:

  • Human performance and occupational health.
  • Applied psychology and pharmacy practice research.

Background:

  • Workload, stress, and performance efficiency are critical in human performance research.
  • Concerns exist regarding pharmacy workload, job stress, and dispensing accuracy.
  • Pharmacy errors impact patient safety and healthcare costs.

Purpose of the Study:

  • To investigate the impact of objective workload on error detection in a simulated pharmacy setting.
  • To examine the relationship between workload, stress, and performance efficiency in pharmacy practice.
  • To assess the effects of varying workload levels on error identification accuracy.

Main Methods:

  • 102 college students evaluated simulated pharmacy prescriptions under low (72 orders/120 min) or high (120 orders/120 min) workload conditions.

  • Utilized a high-fidelity simulated pharmacy environment for realistic task simulation.
  • Measured error detection using cumulative and signal detection theory indices, alongside mood and perceived workload assessments.

    • Main Results:

    • High workload conditions showed significant variations in error identification (sensitivity) and difficulties detecting data-entry mistakes.
    • Modest declines in detection accuracy were associated with increased objective workload.
    • Objective workload did not significantly influence negative mood or perceived workload as hypothesized.

    Conclusions:

    • Elevated workload in pharmacy settings can impair error detection, especially for specific error types like data-entry mistakes.
    • While objective workload impacts accuracy, its effect on subjective stress and perceived workload may be less pronounced.
    • Findings highlight the need for workload management strategies to maintain dispensing accuracy and patient safety in pharmacies.
