    Objectives: The CLEFTSiS (Cleft Service in Scotland) electronic patient record (EPR) contains pre-surgical photographs among other records and this study proposes to assess the reliability of diagnosis and accuracy of the type and extent of cleft. Design and setting: Retrospective study, University of Dundee. Materials and methods: From all 1092 cases contained by the CLEFTSiS EPR from inception (April 2000) until September 2011; syndromic, atypical and submucous clefts, still births, abortuses, cases with non-cleft velopharyngeal incompetence, Pierre Robin Sequence, or Simonart's bands were excluded to leave 730 case records for analysis. Observer 1 recorded the LAHSAL subphenotype using the pre-surgical photographs for each case. Images that were absent, only partially demonstrated the intended anatomical site or were unclear were excluded. The data for Observer 1 was compared to the EPR subphenotype using the Kappa statistic. Thirty randomly selected cases were recoded one month later to calculate intra-observer reliability and three further observers subphenotyped these cases to determine inter-examiner reliability, both using Kappa statistics. Results: Intra- and inter-observer reliability of the LAHSAL system were excellent (0.809-0.992). The correspondence between Observer 1 and the original CLEFTSiS subphenotype was almost perfect (0.812-0.862) except the soft palate and the left alveolus, where agreement was substantial (0.638-0.776). Only 68 (9.3%) of the records fully demonstrated all six anatomical areas of the LAHSAL coding system with intra-oral images being the most frequently deficient views. Conclusions: The subphenotype data held on the CLEFTSiS EPR is accurate but incomplete. Only 9.3% of cases contained all relevant pre-surgical photographs. Subphenotyping using the LAHSAL classification has a high degree of intra- and inter-observer reliability.
