Average length of stay (ALOS) by diagnostic categories is calculated by dividing the number of days stayed (from the date of admission in an in-patient institution) by the number of discharges (including deaths).
Diagnostic chapters (using principal diagnosis) have been defined according to the ICD-9 and ICD-10.
The list of variables included in the chapter on Average length of stay by Diagnostic categories has been extended, following the discussion and endorsement of a new extended shortlist of diagnostic groups at the Meeting of OECD Health Data National Correspondents in September 2005. This new shortlist of hospital diagnostic groups, named the International Shortlist for Hospital Morbidity Tabulation (ISHMT), has already been adopted by Eurostat, NOMESCO and WHO-Europe (for reporting purposes at least, and is now being adopted by the OECD, with the aim of harmonising data collection at the international level (OECD Health Data, 2007). |
