The study revealed that pharmacists perceived the following as causative factors for medication errors (Figures 9, 10, 11):
  • too many telephone calls (62%);
  • overload/unusually busy day (59%);
  • too many customers (53%);
  • lack of concentration (41%);
  • no one available to double check (41%);
  • staff shortage (32%);
  • similar drug names (29%);
  • no time to counsel (29%);
  • illegible prescription (26%);
  • and misinterpreted prescription (24%).

Chi-square Test of Independence revealed statistically significant associations between an overload/unusually busy day to the volume of telephone calls (p<0.01) and volume of customers (p<0.01). Lack of concentration was also significantly associated with an overload/unusually busy day (p<0.05).
