ISO 9001 and JCI preparedness as drivers of quality improvement at a tertiary cardiac care center: a 5-year analysis from Pakistan.
Article in International journal for quality in health care : journal of the International Society for Quality in Health Care, 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
backgroundExternal quality frameworks such as ISO 9001 certification lay the foundation for healthcare quality, patient safety, and operational efficiency, but sustained improvement depends on leadership, a culture of safety, and systems that translate assurance into ongoing learning. Evidence on this transition from low- and middle-income countries, particularly in specialized cardiac care, remains limited.
methodsA retrospective longitudinal analysis of quality assurance data from January 2020 to December 2025 was conducted at the Peshawar Institute of Cardiology (PIC-MTI), Pakistan. Independent-samples t-tests, one-way ANOVA, and Difference-in-Differences (DiD) modeling were applied, with three regional hospitals of similar bed capacity and patient volume serving as a comparison group.
resultsFollowing ISO 9001 certification (February 2022), monthly mortality within 48 h declined from 2.8% (SD ± 0.4%) to 1.9% (SD ± 0.3%) (t = 3.21, df = 58, P = .004). Hospital-acquired infections (HAIs) fell from 3.2% to 2.0% (t = 4.15, P = .002), reaching 1.3% by 2025, with zero CLABSIs recorded in the final quarter following the mid-period intensification of the infection-control bundle. Mean length of stay decreased from 6.2 to 4.7 days [ANOVA: F(2,57) = 8.76, P < .001]. Patient satisfaction rose from 78% to above 90%. DiD modeling found a net 30% reduction in HAIs and 20% reduction in length of stay (LOS) associated with the certification process relative to the comparison trajectory.
conclusionsISO 9001 certification, undertaken alongside deliberate investment in leadership, a culture of safety, and structured use of data, is associated with sustained improvements in clinical outcomes and operational efficiency at a resource-limited cardiac care center that has not yet pursued formal Joint Commission International (JCI) accreditation but is using JCI's standards, as one example of an internationally recognized framework, to guide its preparation. The pattern observed here suggests that a learning quality management system, and not any single certificate or accreditation status, is what converts external standards into measurable gains, offering a replicable model for institutions considering how to move from quality assurance toward continual quality improvement.
