Use of the Delphi process in paediatric cataract management


Purpose To identify areas of consensus and disagreement in the management of paediatric cataract using a modified Delphi approach among individuals recognised for publishing in this field.

Design A modified Delphi method.

Participants International paediatric cataract experts with a publishing record in paediatric cataract management.

Methods The process consisted of three rounds of anonymous electronic questionnaires followed by a face-to-face meeting, followed by a fourth anonymous electronic questionnaire. The executive committee created questions to be used for the electronic questionnaires. Questions were designed to have unit-based, multiple choice or true–false answers. The questionnaire included issues related to the preoperative, intraoperative and postoperative management of paediatric cataract.

Main outcome measure Consensus based on 85% of panellists being in agreement for electronic questionnaires or 80% for the face-to-face meeting, and near consensus based on 70%.

Results Sixteen of 22 invited paediatric cataract surgeons agreed to participate. We arrived at consensus or near consensus for 85/108 (78.7%) questions and non-consensus for the remaining 23 (21.3%) questions.

Conclusions Those questions where consensus was not reached highlight areas of either poor evidence or contradicting evidence, and may help investigators identify possible research questions.
