Purpose This study used the Appraisal of Guidelines for Research and Evaluation (AGREE) II Instrument to evaluate the methodological quality of clinical practice guidelines (CPG) published by the American Academy of Ophthalmology (AAO), Canadian Ophthalmological Society (COS) and Royal College of Ophthalmologists (RCO) for the management of cataract in adults.
Study design An evaluation of the AAO, COS and RCO CPGs using a reliable and validated instrument.
Methods Four evaluators independently appraised the three CPGs using the AGREE II Instrument, which covers six domains (Scope and Purpose, Stakeholder Involvement, Rigour of Development, Clarity of Presentation, Applicability and Editorial Independence). The AGREE II includes an Overall Assessment summarising guideline methodological rigour across all domains, using a 7-point scale where perfect adherence equals a score of 7.
Results Scores ranged from 36% to 75% for the AAO guideline; 45% to 94% for the COS guideline and 23% to 85% for the RCO guideline. Intraclass correlation coefficients for the reliability of mean scores for the AAO, COS, and RCO were 0.78, 0.74 and 0.80; 95% CIs (0.60 to 0.90), (0.45 to 0.88) and (0.53 to 0.91), respectively. The strongest domains were Scope and Purpose (COS, RCO), Clarity of Presentation (COS, RCO) and Editorial Independence (AAO, COS). The weakest were Stakeholder Involvement (AAO), Applicability (AAO, COS) and Editorial Independence (RCO).
Conclusions Cataract surgery practice guidelines can be improved by targeting stakeholder involvement, applicability and editorial independence.
