Summary

Body temperature alterations, including fever and hypothermia, are common in critically ill patients and linked to worse outcomes. Hypothermia in septic shock patients indicates a poorer prognosis compared to fever.

Area of Science:

  • Critical Care Medicine
  • Infectious Diseases
  • Clinical Physiology

Background:

  • Body temperature (BT) dysregulation is a significant concern in critically ill patients.
  • Understanding the incidence and impact of fever and hypothermia is crucial for patient management.

Purpose of the Study:

  • To investigate the occurrence of body temperature alterations in intensive care unit (ICU) patients.
  • To examine the relationship between these temperature changes, infection, and patient outcomes.

Main Methods:

  • A prospective, observational study was conducted in a 31-bed medico-surgical ICU.
  • Adult patients admitted for at least 24 hours over six months were included.
  • Data on body temperature, infection status, Sequential Organ Failure Assessment (SOFA) scores, length of stay (LOS), and mortality were collected.

Main Results:

  • Fever (BT ≥ 38.3°C) occurred in 28.2% and hypothermia (BT ≤ 36°C) in 9.1% of patients.
  • Both fever and hypothermia were associated with higher SOFA scores and increased mortality rates compared to normothermia.
  • Hypothermic patients, particularly those with septic shock, exhibited higher mortality and were older than febrile patients.

Conclusions:

  • Both fever and hypothermia are significant indicators of increased morbidity and mortality in critically ill patients.
  • Hypothermia is associated with a worse prognosis than fever, especially in patients with septic shock.
