Bottom Line: Relative risk and 95% confidence interval were calculated using log binomial regression models.The RR (95% CI) in the 2(nd), 3(rd), and 4(th) quartiles was 1.05 (1.02-1.07), 1.05 (1.02-1.08), and 1.06 (1.04-1.09) for the process score; and 1.02 (1.01-1.04), 1.05 (1.03-1.07), and 1.06 (1.04-1.09) for the outcome score compared to the 1(st) quartile score, respectively.In conclusion, our study design with blinded merge methods shows that total, process, and outcome qualities are related to the return to work of injured workers after controlling for other factors.

ABSTRACT
We examined associations between hospital quality in the workers' compensation system and injured patients' return to work after controlling for injury severity, occupational factors, and demographic factors. Return to work data of injured workers were constructed from 2 datasets: 23,392 patients injured in 2009-2011 from the Korea Workers' Compensation & Welfare Service and return to work data from Korea Employment Information Services. After de-identifying the data, quality scores were matched for each hospital that cared for injured patients. Injury severity was measured by Abbreviated Injury Scales. Relative risk and 95% confidence interval were calculated using log binomial regression models. After adjusting for age, sex, injury severity, occupation, factory size, city, and hospital type, the relative risk (95% confidence interval) for the total score was 1.04 (1.02-1.06), 1.06 (1.04-1.09), and 1.07 (1.05-1.10) in the 2(nd), 3(rd), and 4(th) quartiles, respectively, compared to the 1(st) quartile. The RR (95% CI) in the 2(nd), 3(rd), and 4(th) quartiles was 1.05 (1.02-1.07), 1.05 (1.02-1.08), and 1.06 (1.04-1.09) for the process score; and 1.02 (1.01-1.04), 1.05 (1.03-1.07), and 1.06 (1.04-1.09) for the outcome score compared to the 1(st) quartile score, respectively. In conclusion, our study design with blinded merge methods shows that total, process, and outcome qualities are related to the return to work of injured workers after controlling for other factors.

Mentions: The RTW data of injured workers were constructed from 2 datasets. One included the data of 23,392 injured patients who had closed claims from 2009 to 2011 at the Korea Workers’ Compensation & Welfare Service (COMWEL). The other included RTW data from the Korea Employment Information Services (KEIS) electronic database. KEIS conducted telephone interviews with all participants to elucidate current economic activity status. Using economic activity status, RTW statuses were classified as “unemployment,” “return to former work,” “return to new work,” and “self-employment.” Return to former or new work was categorized as a RTW, and unemployment was categorized as a non-RTW. Among the 23,392 injured patients, we excluded 587 patients classified in the “self-employment” group because it is difficult to define a successful RTW. The Abbreviated Injury Scales (AISs) of the participants were calculated. Next, 7,851 participants with missing AIS data were excluded. Finally, 14,954 patients (10,991 in the RTW group and 3,963 in the non-RTW group) were included in the data analysis (Fig. 1).
