 |   | Benefits 
of Personal Digital Assistance in Decreasing Prescribing Errors:Preliminary 
Experience from a Tertiary Care Hospital
 |   | Tzong-Luen Wang, MD, PhD; Hang Chang, MD, PhD |   |  |   | Abstract ---To 
prevent errors made during the prescription of drugs, we try to understand if 
the personal digital assistance (PDA) can have such benefits. Between January 
1 2001 and March 31 2002, we surveyed the prescription orders from the intensive 
care units (ICUs) of a 961-bed teaching hospital and also prospectively analyzed 
any potentially serious prescribing errors. The PDA was introduced into prescription 
system in January 1 2002. Before the use of PDA, the total prescribing errors 
are 1,505 among the overall 144,481 orders (1.04%). Those errors can be categorized 
into five main factors, including work environment (670 events, 44% of total errors), 
team problem (190, 13%), individual factors (410, 27%), task problems (147, 10%) 
and patient factors (88, 6%). After the PDA era, the incidences of total prescribing 
errors decreased significantly compared to those before PDA use (0.58% vs. 1.04% 
before PDA, P<0.001). Further analysis revealed that the decline in errors 
due to problems of work environment (31%), team (4%) and tasks (5%) were the main 
contributing factors. As to the real incidences, there were significant decline 
in the factors concerning physical environment (0.3? vs. 0.7?, P<0.05), staffing 
(0.3? vs. 2.1?, P<0.001), communication (0.0? vs. 0.4?, P<0.05), responsibility 
(0.1? vs. 0.6?, P<0.05), protocols (0.0? vs. 0.4?, P<0.05) and no routine 
pathways (0.3? vs. 0.7?, P<0.05). In conclusion, the PDA can diminish at least 
half of the common factors affecting prescription errors and also decrease half 
of the incidences. (Ann. Disaster Med 2002;1:20-28) |   | Key
