The challenges of evaluating large-scale, multi-partner programmes: the case of NIHR CLAHRCs
Bibliographic record
Abstract
The limited extent to which research evidence is utilised in healthcare and other public services is widely acknowledged. The United Kingdom government has attempted to address this gap by funding nine Collaborations for Leadership in Applied Health Research and Care (CLAHRCs). CLAHRCs aim to carry out health research, implement research findings in local healthcare organisations and build capacity across organisations for generating and using evidence. This wide-ranging brief requires multifaceted approaches; assessing CLAHRCs’ success thus poses challenges for evaluation. This paper discusses these challenges in relation to seven CLAHRC evaluations, eliciting implications and suggestions for others evaluating similarly complex interventions with diverse objectives.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
