Factors Affecting the Accuracy of Clinical Coding in the Casemix System in a Teaching Hospital: Cross-Sectional Study.
Article in Interactive journal of medical research, 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: Accurate clinical coding is critical in the casemix system to ensure proper resource allocation, health care policy planning, and data reliability. Inaccurate coding can result in significant financial losses to the hospital. To date, the implications of inaccurate coding in casemix implementations in Malaysia have rarely been explored. Objective: This study aimed to evaluate the accuracy of clinical coding and identify factors associated with accurate coding practices in a major teaching hospital in Malaysia. Methods: A cross-sectional study was conducted using 445 inpatient discharge records from Hospital Canselor Tuanku Muhriz from January 2023 to December 2023. Stratified random sampling was applied across 4 departments. Coding accuracy was determined by comparing electronic medical record entries to a gold-standard set by trained coders and specialists. Descriptive and bivariate analyses were performed accordingly. Results: This study found that the overall clinical coding accuracy was 76.4% (340/445). Documentation completeness ( Conclusions: Continuous training and regular audits are recommended to improve coding quality and ensure reliable casemix data for policy and funding decisions.
