Longitudinal associations of nursing staff turnover with patient outcomes in long-term care hospitals in Korea.

AIMS

To describe the characteristics of long-term care hospitals in 2010-2013 and to examine the longitudinal associations of nursing staff turnover with patient outcomes.

BACKGROUND

The number of long-term care hospitals has exploded in Korea since the national long-term care insurance was launched in 2008. The care quality deviation across long-term care hospitals is large.

METHODS

This was a longitudinal secondary data analysis using the Health Insurance Review and Assessment Service's data.

RESULTS

From 2010 to 2013, the nursing staff turnover rate decreased. The number of patients per registered nurse increased while that per total nursing staff and skill mix decreased. All adverse patient outcomes decreased. Higher nursing staff turnover and lower RN proportions were associated with adverse patient outcomes.

CONCLUSIONS

Since the launch of the long-term care insurance, total nursing staffing, turnover rate and patient outcomes have improved, while the skill mix has decreased. Systematic efforts to decrease nursing staff turnover should be implemented for better long-term care patient outcomes.

IMPLICATIONS FOR NURSING MANAGEMENT

In addition to maintaining high levels of nurse staffing and skill mix, supportive work environments and competitive wages and benefits could reduce turnover, and ultimately adverse patient outcomes. Health care policy should separate nursing staffing levels for registered nurses and certified nursing assistants.
