Request
I am writing to make a request under the Freedom of Information act. I am seeking hospital-level activity data within your health authority, as outlined below. Dataset 1: ICD-10 Diagnosis Data For each hospital, please provide: 1. From 2022 up to the latest data available, preferably by calendar year Primary (first) diagnosis ICD-10 codes (three or more characters), chapters A–Q only, including patients outsourced to the private sector 2. Number of cases per ICD-10 code 3. Hospital name and postcode Dataset 2: Procedures / Surgery Data For each hospital, please provide: 4. From 2022 up to the latest data available, preferably by calendar year Primary procedure OPCS codes, all chapters, including patients outsourced to the private sector 5. Number of cases per OPCS code 6. Hospital name and postcode With regard to case numbers for both ICD-10 and OPCS data, we recognise that disclosure controls may apply where case numbers are fewer than five. In such instances, please indicate the value as “<5” or similar format, depending on your small-case policy. We would be grateful if the data could be provided in a machine-readable format (for example, CSV or Excel), if possible. For context, we already hold comparable datasets for most European countries. This information is collected and processed for research and pharmaceutical organisations, where it is used for market analysis and clinical trial planning. We hope this explains the purpose and potential value of supplying the requested data. Please let us know if any clarification is required. I look forward to hearing from you.
Response
Please see attached.
Please note, all values under 5 have been recorded as <5 to prevent the data from being person identifiable.
This is done so under section 40(2) of the FOIA.
