The study of adverse drug events in rheumatoid arthritis and osteoarthritis outpatients at Ramathibodi Hospital
Abstract:
The study was conducted with a cross-sectional design with the objectives to
determine the prevalence and characteristics of adverse drug events (ADEs) and
identify risk factors for ADEs in rheumatoid arthritis (RA) and osteoarthritis (OA)
outpatients who were appointed to the medical clinic at Ramathibodi Hospital between
30th April and 19th July, 2007. ADEs were detected by medical record review and
patient interview. The assessment of adverse event and preventability were performed
by the research pharmacist and validated by physicians.
One hundred and forty-three patients (22 males, 121 females) consisting of
113 RA, 14 OA and 16 RA with OA were recruited. The patients mean age was 54.3
+ 14.3 years old. The results revealed that 68 ADEs were detected from 51 patients.
The prevalence of ADE was 35.7% and ADE rate was 47.6 events per 100 patients.
Thirty ADEs (44.1%) were classified as preventable ADEs. Disease-modifying antirheumatic
drugs (DMARDs) were the most common drug that caused ADEs (59.4%).
Most ADEs expressed as skin and appendage disorders (28.7%) and gastro-intestinal
system disorders (26.2%). Potential risk factors including gender, age (more than 60
years old), number of concurrent diseases, number of prescribed medications, cigarette
smoking history, alcohol consumption history and history of ADEs were not
significantly associated with ADE occurrence.
In conclusion, the prevalence of ADE in RA and OA outpatients was 35.7%
and 44.1% of ADEs were preventable. The risk factors of ADEs should be further
investigated in a large study. Healthcare personals should aware and have a role in the
prevention of ADE problems
