Objective To get known about the disease burden and quality of life (QOL) of rheumatoid arthritis (RA) in China by conducting a systematic review.
Methods The observational studies about the disease burden and QOL of RA in China were systematically searched in the following databases: CNKI, CBM, VIP, WanFang Data, MEDLINE/Pub Med, EMbase, and Science Citation Index. The retrieval time was from January 1st, 1990 to July 31st, 2010. According to the inclusion and exclusion criteria, the literature was screened, the data were extracted, and the methodological quality of the included studies was assessed. The morbidity of RA was pooled by adopting generic inverse variance model, the meta-analyses on 8 dimensions of SF-36 life quality score (LQS) was conducted by suing RevMan5.0 software, the weighted mean difference (WMD) was regarded as the indicator of intervention effect, and the impact of studies’ quality on the results was assessed by sensitivity analysis.
Results A total of 20 studies with medium quality in general were included. The morbidity of RA was 14.7/100 000. The disability adjusted of life years (DALYs) per capita were 4.92. If excluding the cost resulted from DALY, the overall economic cost was RMB 1 250.45 yuan per capita per year; While considering DALY, the cost was RMB 15 717.91 yuan per capita per year. The average cost of outpatient medications was RMB 8 018±17 238 yuan per capita per year. The weighted morbidity was 0.42% (95%CI 0.39% to 0.45%), and it was higher in female than male (P lt;0.05). There was no secular trend and difference between southern and northern (P gt;0.05), but there were statistical significances in the WMD of 8 dimensions of SF-36 LQS. Sensitivity analyses revealed that the weighted pooled results were stable.
Conclusion The epidemiological and economic burden of rheumatoid arthritis are heavier in China, which needs to be concerned by both government and society.
