Patients in England and Wales are supplied by four companies (Air Products, Allied Respiratory, BOC and Linde). These companies have agreed to provide anonymised data on patients to the BTS Home Oxygen database committee.Methods: Data on patients with active orders in June 2007 were supplied. Patient’s service category data were excellent with only 33 missing records, and of these 27 had data on modality of supply, hours of use and litres of oxygen prescribed. Similarly, only 866 postcodes were possibly erroneous as they were unlinkable to the Office of National Statistics Postcode Directory File for February 2007. Another well-completed data field from the HOOF forms was date of birth; only 1045 records were missing and 118 obviously erroneous. NHS numbers were missing for 8107 records and another 8732 were not 10 characters in length. For three contractors, clinical diagnosis codes were present in only 29% of records. The number of patients in age groups 0, 1–4, 5–9, 10–14, etc and 85+ plus were counted after eliminating possible duplication of patients and linked to the most recent (2005) quinary mid-year residential populations estimates from the Office of National Statistics website (http://www.statistics.gov.uk).Abstract P1 Results: There were 76 753 home oxygen users, 3136 (4.1%) were paediatric patients aged below 17 years. The commonest age for home oxygen was 77 years (range 0–107). Prevalence fell from 0.73 per … ER -
