Pain catastrophising as a risk factor for hospitalisation and readmissions in fast-track hip and knee arthroplasty, an observational multicentre cohort 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: A preoperative pain catastrophising scale (PCS) of >20 is associated with increased postoperative pain, development of chronic pain, and impaired function after hip and knee arthroplasty. However, whether PCS >20 is associated with prolonged length of hospital stay (LOS), readmissions, and reduced likelihood of same-day discharge is unknown.The primary aim of this study was to investigate the association between a preoperative PCS of >20 and a LOS >2 days Secondary aims were to investigate the association of PCS >20 with 90-day readmission rate and admission postoperatively. Methods: This prospective cohort study is from eight Danish arthroplasty departments with similar fast-track protocols. Data on preoperative PCS, patient characteristics, and prescribed medications were collected. Postoperative follow-up was conducted through patient records and self-reported questionnaires. Binary multilevel logistic regression was used to investigate the association between PCS >20 and hospital LOS of >2 days, 90-day readmission rate due to pain or insufficient mobilisation, and immediate admission despite scheduled same-day surgery. Results: The study period ran from September 2022 to June 2025. Of 15 965 procedures, 6728 (43%) were total hip arthroplasties (THA), 5992 (38%) were total knee arthroplasties (TKA), and 2974 (19%) were unicompartmental knee arthroplasties (UKA). Of these, 5225 (33%) reported a preoperative PCS >20. Median hospital LOS was 1 day, 90-day readmission rate was 7.3%, and 5464 (35%) of patients were scheduled for same-day discharge. For the total cohort, PCS > 20 was associated with LOS >2 days (odds ratio [OR]: 1.54; 95% confidence interval [CI]: 1.29-1.83; Conclusions: A preoperative pain catastrophising scale of >20 was associated with increased hospital length of stay and increased 90 day readmission rate despite planned same-day discharge after fast-track total hip arthoplasty, total knee arthoplasty and unicompartmental knee arthroplasty surgery.
