Intensive care unit mortality and cost-effectiveness associated with intensivist staffing: a Japanese nationwide observational study
Authors' conclusion
ICU1/2 is associated with lower ICU patient mortality than ICU3/4. Treatments under ICU1/2 are more cost-effective than those under ICU3/4, with an ICER of < 5 million JPY/QALY.
