บทคัดย่อ

Objective  To design a preventing predispensing error system by 5S activities. 

Materials and methods  The process was divided into 4 steps including data reviewing, analyzing of occured predispensing errors, designing/implementing system and evaluating. The Deming cycle was adjusted in  three cycles. This study was conducted from August 2014 to July 2015 at out patient pharmacy department, Srithanya Hospital.                               

Results  Retrospective data reviewing showed that the number of predispensing errors were 837; 340 errors were wrong amount (40.6%), 228 errors were wrong strength (27.2%), 98 errors were wrong drug and wrong regimen equally (11.7%). Analyzing of this occured predispensing errors revealed that pharmacy department’s staff did not perform 5S activities. The designing system consisted of  quantity table, size symbol, type symbol and 5S activities checklist. Before implementing system in January, the rate of predispensing errors per 1,000 prescriptions was 48.2. First implemention and evaluation in February, the rate of predispensing errors per 1,000 prescriptions was 46.8. Adjusting some size and type symbols on second implemention and evaluation in March, the rate of predispensing errors per 1,000 prescriptions was 32.0. Meeting for reducing predispensing errors was arranged  in April. The rates of predispensing errors per 1,000 prescriptions from April to July were 29.8 ,27.4 ,30.3 and 35.1, respectively.

Conclusion Preventing predispensing errors system by 5S activities can reduce predispensing errors. Thus pharmacy department’s staffs should be encouraged to perform continuously.
