A national reporting system has recently been developed, which specifically monitors bed occupancy in clinically inappropriate wards, to diminish adveise effects. While nearly all cataract surgeries have for a long time been performed as day care, the use of day care has spread to many other procedures. For example, the share of tonsillectomy (the removal of tonsils) carried out as same-day surgery has increased from about 20% in 2005 to over 70% in 2015. Most of the over 100 registers are built around specific diagnoses and mainly contain medical and epidemiological information.
