WebAug 26, 2024 · SMR = number of observed deaths / number of expected deaths. SMR = 149/119.8 = 1.24 (2 d.p.) 1.24 > 1.0, therefore there were excess deaths in hospital A’s ICU. 119.8 approximates to 120. Number of excess deaths = 149 -120 = 29 excess deaths. The SMR could also be expressed as 124 (124 > 100, so again this shows excess deaths).
