Increasing rates for certification of visual impairment at Royal Cornwall Hospital Trust: An audit series

The audit series investigated how rates of Certification of Visual Impairment (CVI) at Royal Cornwall Hospital Trust (RCHT) performed when compared against Public Health England (PHE) indices. Our aim was to assess whether CVI rates could be improved by promoting clinician awareness. We collected CVI data for Sight Impairment (SI) and Severe Sight Impairment (SSI) from a prospective MS Excel database maintained at RCHT for all certifications between 1 August 2014 and 31 July 2016. Annual local certification rates were compared to regional and national rates using data from Public Health Outcomes Framework (PHOF) for glaucoma, age-related macular degeneration (ARMD), and diabetic eye disease. We found that overall rates of certification were above both those of the South West region and England; however, certifications for ARMD and glaucoma fell below the regional and national rates. Reasons for this may include variations in ethnicity, introduction of anti-vascular endothelial growth factor (anti-VEGF) agents, and/or the potential delay in CVI completion while under treatment for ARMD. We concluded that raising awareness among clinicians did not prove a satisfactory intervention to improve certification rates. In response to these findings, RCHT and a local charity, iSight Cornwall, have jointly funded an Eye Clinic Liaison Officer (ECLO) to enhance the certification process. This is expected to deliver immediate service improvement. Considerable overlap in dual diagnoses presents a problem in interpretation of CVI data, which could be targeted by the implementation of electronic certification
