Perioperative Medicine for Older People Undergoing Surgery Scale Up (POPS-SUp): study protocol.
Article in BJS open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSurgery provides definitive management of many age-related diseases, relieving symptoms or extending life. Age-related physiological decline, multimorbidity, and frailty predispose older people to postoperative complications and incomplete functional recovery, with resultant health and social care costs. These age-related conditions can be optimized using Comprehensive Geriatric Assessment (CGA), thus mitigating perioperative risk to improve clinical outcomes with cost-effectiveness. National organizations advocate CGA-based services for older surgical patients. However, there is variation in the provision of CGA-based perioperative medicine for older people undergoing surgery (POPS) services across the UK National Health Service, resulting in inequitable access for older surgical patients at higher risk, unnecessary deaths, complications, and financial cost. The aim of the POPS Scale Up (POPS-SUp) study is to determine whether CGA-based POPS services can be implemented at scale to cost-effectively improve clinical outcomes for older patients undergoing surgery.
methodsA mixed-methods hybrid implementation-effectiveness interrupted time series study will examine the use of a coproduced implementation strategy to embed CGA-based POPS services at scale in the UK. Co-primary implementation-effectiveness outcomes will be used, namely reach and length of hospital stay, respectively. Evaluation will include an embedded process evaluation, quantitative evaluation of clinical effectiveness and cost-effectiveness, and qualitative appraisal of patient and staff experience. The proposed analysis is to embed a process evaluation using real-time framework analysis, enabling iterative refinement and evaluation of the implementation strategy. Accepted interrupted time series analysis will be used to examine and compare outcomes per participating site. A predefined dissemination strategy has been co-designed with patients/carers, clinical community of practice, and organizational bodies.
conclusionThe anticipation is that POPS-SUp will have impact at the individual (patient and clinician), organizational, and policy levels in the perioperative setting, but with additional potential application to other clinical settings.Registration numbers: ISRCTN 45327 (https://www.isrctn.com/); NIHR 157443 (https://www.nihr.ac.uk/).
