National survey of protocols for day-case hip and knee arthroplasty in the UK.
Article in Bone & joint open, 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
Aims: Day-case joint arthroplasty, where patients are discharged on the day of surgery, is increasingly used to meet rising demand in a resource-efficient manner. NHS England guidance states that all patients should be placed on an ambulatory pathway (zero to one night stay). However, little is known about the prevalence, structure, and implementation of day-case protocols across the UK. Methods: An online survey was sent to all NHS institutions performing hip or knee arthroplasty. Respondents reported the presence of day-case, ambulatory (zero to one night stay), or generic enhanced recovery protocols. Data were collected across 21 questions covering key perioperative domains and analyzed descriptively, and model health system data was used to assess length of stay (LoS). Results: Overall, 63 responses were received covering 86 hospitals (56 trusts), of which 78 (91%) perform day-case surgery. In total, 41 (48%) had a dedicated day-case protocol, 23 (27%) had ambulatory protocols, and 15 (17%) used generic enhanced recovery pathways. Only 22% of hospitals with a day-case pathway placed all patients on it by default. Protocol content showed substantial variation, including the use of sedation as part of anaesthesia (49%), presence of therapy services beyond 17:00 (59%), and nurses competent in assessing day zero mobility (56%). One third of hospitals had no mechanism for patients to contact out-of-hours support. LoS was shorter in hospitals using day-case or ambulatory protocols when compared with those that did not, however, this did not reach statistical significance. Conclusion: While day-case joint arthroplasty is widely performed in the NHS, dedicated protocols are used in fewer than half of hospitals, and considerable variation exists. These results can be used collaboratively by hospitals that are trying to establish pathways, and to guide further research aiming to identify best practice and provide standardization for day-case protocols.
