Will the increase of medical equipment affect medical expenditure? Empirical evidence from a quasi-experiment in China.
Article in BMC health services research, 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
backgroundMany studies have shown that using new technologies and medical equipment contributes to increasing health expenditure. Relatively less empirical studies have measured the impact of medical equipment on rising medical costs in China. Against this backdrop, we aim to examine whether the large-scale medical equipment deployment explains the increase in health expenditure.
methodsQuasi-experimental research design with a difference-in-differences approach was adopted to explore whether an increase in the number of large-scale medical equipment impacts on outpatient and inpatient costs. Data were obtained from the 2011-2017 Health Financial Annals in Shaanxi province, China.
resultsThe increase in the number of large-scale medical equipment by 1 - regardless of the initial configuration - resulted in the increase of the average cost per outpatient visit and the average cost per inpatient visit by 10.6% (p < 0.05) and 8.0% (p < 0.05), respectively. Our complex difference in differences model illustrates that the increase in the number of large-scale medical equipment by 1 - regardless of the initial configuration-results in an increase in the average diagnostic cost per outpatient visit and the average diagnostic cost per inpatient visit by 27. 3% (p < 0.01) and 25. 5% (p < 0.01), respectively.
conclusionsOur findings show that the medical expenditure differs significantly with the increase in the number of large-scale medical equipment. This study mainly revealed the relationship between the growth of the number of large-scale medical equipment and medical expenditure. Our novel perspective was used to measure the phenomenon of excessive use, and to explain the social phenomenon of inaccessible and expensive medical care in China.
