Why the study?

Poor sleep has been positively associated with nurses' medical errors, but the relationship between sleep quality and heart rate variability among female nurses required investigation.

Is poor sleep quality associated with reduced heart rate variability in female nurses?

Population

393 female nurses employed in a medical center in Taiwan

Comparison

Shift-work nurses vs non-shift nurses and differing sleep quality

Design

Descriptive cross-sectional correlational study

Key result

Poor sleep quality among female nurses was negatively correlated with heart rate variability, including total power (r = -0.425, p < 0.05).

Overview

Poor sleep quality was associated with HRV changes in nurses; leaves open whether interventions improve autonomic function or reduce errors.

Structured PICO

Is poor sleep quality associated with reduced heart rate variability in female nurses?

P
Population
393 female nurses employed in a single medical center in Taiwan, evaluated for sleep quality and heart rate variability.
E
Exposure
Shift work and poor sleep quality (observational exposure)
C
Comparator
Non-shift work and better sleep quality
O
Outcome
Heart rate variability (HRV) including total power, low frequency, and low frequency/high frequency ratiosurrogate

Main Result

Effect estimate: r = -0.425

p-value: p=<0.05

Poor sleep quality is highly prevalent among female nurses and is associated with reduced heart rate variability, indicating autonomic nervous system impairment.

Cite This Study

Hsu et al. (2021) conducted a cross-sectional in Poor sleep quality (n=393). Sleep quality was evaluated on Heart rate variability (total power, low frequency, and LF/HF ratio) (r = -0.425, p=<0.05). Poor sleep quality among female nurses was negatively correlated with heart rate variability, including total power (r = -0.425, p < 0.05).
