Primary care gatekeeping and referrals: effective filter or failed experiment?

Open access
Forrest, Christopher B·2003·BMJ

Abstract

was similar to that found in the single previous randomised controlled trial comparing five statins.5 We are aware that there have been no direct comparisons of the clinical outcomes in patients taking different statins and, realistically, such studies are unlikely.Initial serum cholesterol concentrations were higher in our study than in the randomised controlled trials, therefore the absolute risk reductions in primary care patients (and hence the overall population benefits) may be greater than thought.Achieving target cholesterol values of <5mmol/l may, however, be unrealistic.We thank the participating general practices; Andy Meal, Vicky Hammersley and Lynne Wright for advice on MIQUEST queries; and Lindsay Groom and Janet Yates for their comments on a late draft.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
