Impact of reimbursement reform on Finnish occupational health service trends in 2018-2022: an interrupted time series analysis.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesIn Finland, the reimbursement system for occupational health services (OHSs) was reformed on 1 January 2020 to shift the focus from curative care to preventive OHS and promote employees' work ability. We investigated the OHS trends and how the reimbursement affected them.
designA register-based study that used moving averages to visualise OHS trends in 2018-2022. To detect the impact of the reform, we used two types of interrupted time series (ITS) analyses: a linear regression model (ITS linear model) and an analysis of variance (ANOVA) lagged dependent variable model (ITS ANOVA).
settingRetrospective register data (2018-2022) of a major OHS provider in Finland. OUTCOME MEASURES: Time spent on OHS activities and the number of OHS activities per 1000 individuals per month. Level and slope changes in these measures in the ITS linear model, as well as the changes in these measures in the ITS ANOVA.
resultsAfter the reimbursement reform, the trend of preventive OHS shifted from a decline to a rise. Among nurses, the ITS linear model also showed changes of 0.6 hours (95% CI: 0.2 to 0.9) and 0.9 activities (95% CI: 0.2 to 1.7) per 1000 individuals per month. Throughout the study period, the trend of work ability health examinations for both physicians and nurses rose, with a monthly slope change of 0.03 hours (95% CI: 0.01 to 0.04) per 1000 individuals among nurses in the ITS linear model. We observed a descending trend in curative care with a monthly decrease of 14.3 hours (95% CI: -25.5 to -3.1) and 32.4 activities (95% CI: -64.1 to -0.1) per 1000 individuals by all professionals in the ITS ANOVA.
conclusionsAfter the 2020 reimbursement reform, the focus of OHS shifted from curative care to preventive OHS. It is likely that the reform affected these changes, although other factors may also have influenced them.
