Patient reported symptoms, body temperature and hospital mortality: an observational study in a low resource healthcare environment.

Background: Fever is a common presenting complaint of patients, especially in sub-Saharan Africa. Although most medical authorities consider fever to be synonymous with an elevated body temperature the relationship of the complaint of fever made by patients to temperature has not been well defined.

Aim: This study examined the relationship of the complaint of fever to temperature on and after admission and in-hospital mortality.

Method: Observational study in a low-resource Ugandan mission hospital.

Results: Out of 2122 alert patients admitted between 9 August 2016 and 5 January 2018, 349 (16.4%) complained of fever: these patients were no more likely to have an abnormal temperature or die in-hospital than those not complaining of fever. Of the 707 alert patients admitted after 1 July 2017, 422 were interviewed in detail about their symptoms: only rigors, feeling intermittently hot and cold, and anorexia were statistically related to the complaint of fever, and only rigors to an admission temperature >38°C. No symptom or sign was associated with a temperature ≤36°C: cold and clammy skin was the only finding associated with in-hospital death. On logistic regression the only independent predictors of mortality were: the National Early Warning Score, impaired mobility on presentation and cold and clammy skin.

Conclusion: In this study, the term fever used by patients and raised body temperature were not synonymous. Although fever and related symptoms reported by patients are common presenting complaints only the finding of cold and clammy skin was associated with in-hospital mortality.
