Therefore, the proportion of patients re-admitted to hospital within 30 days has been used and collected by the OECD as an indicator of the lack of proper management of mental health conditions outside of hospital (OECD, 2013a). Whilst there are some limitations with regards to this data, including the small number of countries able to distinguish between “planned” and “unplanned” re-admissions to hospital, this can be a useful indicator (OECD, 2013b). Unplanned re-admissions to the same hospital for schizophrenia and bipolar disorder in Norway are quite high.
