Should respiratory rate be measured on admission over a few seconds by a smartphone application or over 15 minutes by a piezoelectric device? A prospective observational pilot study of acutely ill medical patients admitted to alow-resource Ugandan hospital

Original Articles, Volume 23, Issue 3, Pages 97– 168 (2024)

Background: the optimal period over which respiratory rate should be measured is uncertain.Setting: medical ward of low resource Ugandan hospital,Methods: comparison of the first respiratory rates measured on admission over seconds using a smartphone application with measurements over 15 minutes using a piezoelectric device.Results: There was a poor correlation between respiratory rates measured by the...

A prospective, observational study of the performance of MEWS, NEWS, SIRS and qSOFA for early risk stratification for adverse outcomes in patients with suspected infections at the emergency department

Original Articles, Volume 20, Issue 2, Pages 89-156 (2021)

Background: Many patients with suspected infection are presented to the emergency Department. Several scoring systems have been proposed to identify patients at high risk of adverse outcomes.

Methods: We compared generic early warning scores (MEWS and NEWS) to the (SIRS) criteria and quick Sequential Organ Failure Assessement (qSOFA), for early risk stratification in 1400 patients with suspected infection in the ED. The primary study end point was 30-day mortality.

Results: The AUROC of the NEWS score for predicting 30-day mortality was 0.740 (95% Confidence Interval 0.682-0.798), higher than qSOFA (AUROC of 0.689, 95% CI 0.615- 0.763), MEWS (AUROC 0.643 (95% CI 0.583-0.702) and SIRS (AUROC 0.586, 95%CI 0.521 - 0.651). The sensitivity was also highest for NEWS≥ 5 (sensitivity 75,8% specificity of 67,4%).

Conclusion: Among patients presenting to the ED with suspected infection, early risk stratification with NEWS (cut-off of ≥5) is more sensitive for prediction of mortality than qSOFA, MEWS or SIRS, with adequate specificity.
