Vitrectomy After Cataract Surgery as a Patient Safety Indicator: A Rapid Review to Support Benchmarking Within the Austrian Inpatient Quality Indicators Framework.

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
Cataract surgery is the most common surgical procedure in high-income countries. It is considered relatively safe and rarely has serious complications. Nevertheless, a quality assessment of the care structures is important, and Inpatient Quality Indicators (IQIs) have already been established at the system level. The Austrian Inpatient Quality Indicator system (A-IQI) uses a nationwide benchmark and annually reports the vitrectomy rate based on all cataract operations as a quality indicator for complications. The primary objective of this study is to validate the Inpatient Quality Indicator for Vitrectomy as a measure of complications during or after cataract surgery, using international comparative values. We conducted a rapid review, searching for studies in MEDLINE and EMBASE from 2012 to 2024. For the data synthesis, we applied a meta-analysis. A total of 3792 studies were screened, of which 25 were eligible. The rapid review showed that the vitrectomy rate following cataract surgery was 1.29% [95% uncertainty interval (UI) 0.78-2.11, I2 =99.6%] when reported per eye. In contrast, the pooled vitrectomy rate was 0.80% (95% UI: 0.37-1.74, I2 =99.6%) when reported per patient. This shows that the Austrian benchmark is lower in terms of procedures, but higher in terms of patients. However, due to the A-IQI data using procedures rather than patients as the denominator, a comparison with procedural reporting is recommended. The vitrectomy rate in the A-IQI reporting falls short. The literature shows differences in terms of severity and the number of operations performed per surgeon. Though the A-IQI process and the claims data used show potential, it can be seen that the A-IQI indicator underestimates the rates of complications.
