1 · What the graph read from it

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.

2 · The registry

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: Stakeholders within a publicly funded healthcare system have a duty to consider costs and economics, to utilize finite resources in the most effective manner. We aimed to quantify the postoperative costs associated with mitral valve repair (MVR) at the Foothills Medical Centre in Calgary, Canada. Methods: A retrospective review of patients who underwent MVR from January 2020 to November 2023 was performed. For patients undergoing minimally invasive mitral valve surgery (MIMVS), a postoperative rapid recovery (RR) protocol was introduced. Postoperative costs were analyzed for 3 comparator groups: MIMVS with RR (MIMVS-RR), MIMVS without RR, , and median sternotomy. Results: Care in the cardiovascular intensive care unit (CVICU) is 2.83 times more expensive than care on the cardiac surgery ward. Length of stay (LOS) in the CVICU was identified to be the primary driver of postoperative costs. The CVICU LOS and total LOS for sternotomy patients was longer than those of MIMVS patients. This difference translated to increased postoperative costs for sternotomy compared to MIMVS on a per-patient basis. The postoperative costs associated with sternotomy are 1.42 times higher than those for MIMVS-RR. When modelled with 200 patients, MIMVS-RR represents a postoperative cost-savings of $3.657 million CAD, compared to sternotomy. Conclusions: Following MVR, a minimally invasive approach demonstrates cost-savings, compared to a sternotomy. Reduced CVICU LOS was the primary driver of cost-savings for MIMVS. Further analysis and investigations are required to fully quantify the true economic benefits of MIMVS-RR at our centre.
