Frequency of vital sign measurement among intubated patients in the general ward and nurses’ attitudes toward vital sign measurement

Abstract

Purpose

The lack of recognition of respiratory distress may result in emergency tracheal intubation in the general ward. However, few studies have examined the differences in the frequency of vital sign measurement between patients with and without emergency tracheal intubation in the general ward. Thus, this study aimed to investigate the differences in the frequency of vital sign measurements between patients with and without emergency tracheal intubation.

Patients and methods

This is a single-center, retrospective, observational study of unplanned intensive care unit (ICU) admissions from the general wards between December 2015 and February 2017. This study included patients with emergency medical intubations in the general ward who were then transferred to the ICU. Vital signs measured within 24 hours prior to ICU admission were compared between patients who did and did not require emergency tracheal intubation in the general ward. A survey was also conducted to explore the nurses’ attitudes toward vital sign measurements.

Results

Compared with other vital signs, the respiratory rate was significantly less frequently measured. Moreover, the frequency of respiratory rate measurement was lower in the 38 patients who were intubated than in the 102 patients who were not intubated in the general ward (P=0.07). The survey revealed that 54% of the participating nurses considered assessment of the respiratory rate as the most troublesome nursing task and ~15% of nurses did not routinely measure respiratory rates.

Conclusion

Respiratory rate was less frequently assessed in deteriorating patients in the general ward, possibly because it was considered a troublesome task.
