Data notes
Overview
- Summary of dataset and variables
This dataset shows the number of certifications of vision impairment (CVI) by patient residence and service location health board in Wales, alongside a total for England. It highlights cross-border flows where patients live in one area but are certified in another. The data is broken down by patient health board and service health board for Wales, with England included as a single total.
The dataset provides insight into patterns of patient movement for certification services across Welsh health boards and between Wales and England over time.
- Data collection or calculation
The data for all certification services provided in Wales are provided by NHS Shared Service Partnership (NWSSP), whereas for Welsh residents certified in England the data is provided by Moorfields Hospital.
Certifications of vision impairment are grouped by financial year, service location health board, and patient residence health board. Patient and service health boards in Wales are identified using standard codes, with England represented as a single category. Counts are calculated for each combination. To ensure completeness, all possible combinations of year, service health board, and patient health board are included, with missing values filled to reflect zero counts where no certifications occurred.
Cross-border flows—patients living in one area but certified in another—are captured to provide insight into patterns of service use across Wales and between Wales and England.
- Statistical quality
The certification data from Moorfields Hospital, which covers Welsh patients receiving services in England, will be available after the initial publication of the Welsh service data. As a result, this English data will initially be omitted and left blank in the published dataset.
