Hospital Bed Capacity Influences Patient Charges in Outpatient Robotic Total Knee Arthroplasty: A Propensity-Matched Study.

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 rise of robotic-assisted total knee arthroplasty (RA-TKA) surgeries has correlated with increased outpatient procedures aimed at improving efficiency and outcomes. However, patient charges vary widely due to differences in reimbursement structures, resource utilization, and the higher supply costs associated with robotics. Little is known about the impact of institutional characteristics, specifically hospital bed capacity, limiting understanding of charge variability and cost-control strategies. This study aims to examine whether hospital size affects patient charges for RA-TKA, focusing on (1) total charges and (2) operating room (OR) charges. Methods: Outpatient RA-TKA cases from January 1, 2017, to December 31, 2021, were identified from a national database. Hospitals were categorized by bed capacity: <300 beds and ≥ 300 beds. A 1:1 propensity score match controlled for demographics, clinical characteristics, and insurance status, resulting in 464 patients per group. Outcomes included total patient charges and OR (anesthesia, OR block time, and postanesthesia care) charges. Statistical analyses included Results: Hospitals with ≥300 beds showed significantly higher mean total charges ($65,315.6) compared to hospitals with <300 beds ($53,427.5) ( Conclusions: Larger hospitals were associated with significantly higher total and OR patient charges for robotic RA-THA, even after matching for clinical and insurance-related factors. These findings suggest that hospital size may be associated with variation in charge profiles beyond patient and payer characteristics.
