One-year mortality rates after standardized management for emergency laparotomy: results from the Swedish SMASH study

• Background: Patients who require an emergency laparotomy suffer from high mortality and morbidity rates. Studies have shown that the standardization of perioperative management reduces complications in the short term. The aim of the present study was to report long-term mortality rates for the SMASH (Standardized perioperative Management of patients operated with acute Abdominal Surgery in a High-risk and emergency setting) study, as well as short- and long-term outcomes for different age groups within the SMASH study. Methods: A prospective intervention study was introduced in 2018, with the aim of investigating the introduction of a standardized protocol for emergency laparotomy. For 42 months, intervention patients were managed according to the protocol and outcomes were then compared with those of historical controls. Results: A total of 1344 unique patients were included (681 in the intervention group and 663 in the control group). The 90-day mortality rate was 14.1 per cent in the intervention group and 20.8 per cent in the control group (P = 0.002) and the 1-year mortality rate in adjusted analyses was 19.7 and 27.8 per cent respectively (P =< 0.001). An age-related subgroup analysis showed that the oldest patients (76 years and older, 260 in the intervention group and 240 in the control group) had a 1-year mortality rate of 29.6 and 43.8 per cent respectively (P = 0.004) and a mean duration of hospital stay of 9.9 and 11.6 days respectively (P = 0.027). Among older adults (61-75 years), the mean duration of hospital stay was 11.7 days in the intervention group compared with 15.1 days in the control group (P = 0.009) and the mean duration of ICU care was reduced to 4.49 days compared with 7.29 days (P = 0.046). Conclusion: The standardized protocol associated with an emergency laparotomy appears to be beneficial, even in the long term. For elderly patients, it appears to reduce mortality rates and the durations of hospital stay and ICU care.
