Status and associated factors of gerontological nurse specialists' core competency: a national cross-sectional study

Nurses' core competency directly affects patients' safety and health outcomes. Gerontological nurse specialists play an essential role in improving older adults' health status. However, little is known about their core competency level and the factors influencing core competency. Therefore, this study aimed to investigate the status of core competency and factors influencing the core competency of gerontological nurse specialists in China.

A multicenter cross-sectional study was conducted on gerontological nurse specialists certified by province-level or above organizations across China between March 2019 and January 2020. The Revised Core Competency Evaluation Instrument for Gerontological Nurse Specialists was used to measure participants' core competency. The median, frequencies, and percentages were used to describe participants' characteristics and level of core competency. Multivariate stepwise regression analysis was applied to analyze the factors influencing core competency.

The median score of gerontological nurse specialists' core competency was 3.84, and professional development skills and research and analysis decision-making skills had the lowest scores among the dimensions. The multivariate stepwise regression analysis showed that individual-level factors (i.e., working experience length of geriatric nursing and attitudes toward caring for older adults), employer-level factors (i.e., departments, job responsibilities, the degree of satisfaction toward the attention and support and the promotion rules provided by the hospital or department), and training-associated factors (i.e., economic zone where training organizations are located and the degree to which the training content met clinical needs) are independently associated with gerontological nurse specialists' core competency level (P < 0.05).

This study showed that gerontological nurse specialists' core competency needs further improvements, especially regarding professional development skills and research and analysis decision-making skills. Additionally, individual-, training-, and employer-level factors could influence their core competency level, indicating that interventions targeting these factors could be applied to improve the core competency of gerontological nurse specialists.
