The nursing-midwifery workforce size significantly influences the reduction of neonatal mortality rate

Abstract

Purpose

This study aimed to quantify the confounded and independent role of nursing-midwifery workforce size (NMWS) in protecting against neonatal mortality (NMR) globally and regionally.

Methods

Scatter plots, bivariate correlation, partial correlation, and multiple linear regression analyses were conducted to assess the correlations between NMWS and NMR. This cross-sectional study fully accounted for potential confounding effects of economic affluence, total fertility rate, and urbanization on this relationship. Countries were categorized to explore regional variations in the protective role of NMWS in reducing NMR.

Results

Explaining 55.76% of NMR variance worldwide, NMWS correlated to NMR negatively and significantly. NMWS still significantly correlated to NMR, but only explained 9.12% of NMR variance when the confounding effects of economic affluence, total fertility rate and urbanization were removed in partial correlation. Linear stepwise regression identified NMWS as the third most significant variable influencing NMR variance worldwide. NMWS correlated to NMR significantly and consistently in different country groupings, especially in developing countries. This suggested that nursing shortage is a significant global issue, but worse in developing countries.

Conclusions

NMWS appears to have been a protective factor against NMR globally, particularly in developing nations. This protective effect remained significant even after adjusting for economic affluence, total fertility rate, and urbanization. The consistent negative correlations observed between NMWS and NMR, both globally and regionally, highlight the importance of addressing the chronic shortage of nursing and midwifery personnel, prompting healthcare authorities to prioritize this issue.
