For 2007-08, almost all public hospitals provided data for the NHMD, withthe exception of a mothercraft hospital in the ACT. The great majority of private hospitals also provided data, except for private day hospital facilities in the ACT, the single private free-standing day hospital facility inthe the NT, and a small private hospital in Victoria. Inaccurate responses may occur in all data provided to the Institute, and the Institute does not have direct access to hospital records to determine the accuracy of the data provided. However, the Institute undertakes extensive validation on receipt of data. Data are checked for valid values, logical consistency and historical consistency. Where possible, data in individual data sets are checked with data from other data sets. Potential errors are queried with jurisdictions, and corrections and resubmissions may be made in response to these edit queries. The AIHW does not adjust data to account for possible data errors or missing or incorrect values. For Admitted patient data, Indigenous status is of sufficient quality for statistical reporting purposes for the following jurisdictions: NSW, Victoria, Queensland, SA, WA, the NT (public hospitals only). Adjustments for Indigenous under-identification have been made at the national level using an adjustment factor of 89 per cent. No adjustments for under-identification have been made at the state/territory level. Approximately 2 per cent of hospital records in the six jurisdictions had missing Indigenous status information. No adjustments have been made for missing Indigenous status information. Two years of data have been combined to ensure confidentiality of responses.
