Factors associated with patient safety in neonatal intensive care units: A multicenter study using ordinal logistic regression

Aim This study aimed to identify nurses' staffing levels, neonatal infection experience, infection control knowledge, and infection control performance, as well as levels of patient safety, and to verify the factors influencing patient safety related to infection control in multi-centered neonatal intensive care units (NICUs). Methods A self-administered questionnaire was completed by 251 NICU nurses working in seven hospitals throughout South Korea. The data were collected in February 2019 and analyzed using generalized ordinal logistic regression. Results The distribution of patient safety was as follows: level 1 (very poor) 0%, level 2 (poor) 6.8%, level 3 (fair) 29.7%, level 4 (good) 35.0%, level 5 (very good) 21.5%, and level 6 (excellent) 7.2%. The factors influencing patient safety differed across the different levels of patient safety. Comparing patient safety level 2 with the other levels (3, 4, 5, 6), the nurse staffing level (b = 1.12) was a significant influencing factor. Comparing patient safety levels 2, 3, 4 and 5 with level 6, the influencing factors were neonatal infection experience (b = -1.18) and infection control performance (b = 5.77). Conclusion The nurse staffing level was a factor when patient safety levels were low, and nurses' neonatal infection experience and infection control performance were factors when patient safety levels were high. Institutional policy efforts are required to identify patient safety levels in NICUs to develop comprehensive strategies to ensure appropriate nurse staffing and enhance neonatal infection control performance to prevent infections.
