Quality Assessment of the Iran Intensive Care Unit Registry: A Validation Evaluation Using International Medical Registry Frameworks (2017-2024).
Article in Iranian journal of medical sciences, 2026. 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
Background: The Iran intensive care unit registry (IICUR) was established to systematically collect highquality clinical data from critically ill adult patients nationwide. This registry was created to fill a major gap in Iran by providing the first coordinated national intensive care unit (ICU) data system to support benchmarking, quality improvement, and research. This study aimed to assess the registry's data quality, representativeness, and performance using internationally recognized evaluation frameworks. Methods: This validation study included consecutive adult ICU admissions (aged≥16 years) recorded in the IICUR between October 2017 and October 2024 across 39 ICUs in 16 hospitals from various regions of Iran. Data quality was assessed based on the directory of clinical databases (DoCDat) and Arts et al., frameworks. Evaluated domains included case representativeness, variable completeness, data validation processes, and coding reliability. Statistical analyses were performed using SPSS software (version 24). Results: Overall, 34,550 ICU admissions were registered (36% surgical, 64% medical). The patient's mean age was 49.4 years, with an average ICU stay of 6.7 days. The registry achieved a median DoCDat score of 3.0 (on a 1-4 scale), indicating strong national coverage, standardized data definitions, and high recruitment completeness. Trauma, neurological, and respiratory disorders were the most common admission causes. ICU and hospital mortality rates were 13.8% and 16.4%, respectively. Despite its strengths, enhanced data validation and postdischarge followup were required. Conclusion: The IICUR demonstrated high methodological standards, providing a robust national platform for benchmarking, policy development, and critical care research in Iran.
