External influencing factors on missed care in Austrian hospitals: Testing the theoretical antecedents of missed care using structural equation modelling.

Problem: Missed Nursing Care (MNC) is an error of omission which occurs when a necessary nursing intervention is not initiated, is not completed, or when it is delayed. The MNC model explains this problem and describes four antecedents that can lead to MNC: (1) demand for patient care, (2) available human resources, (3) material resources, and (4) and relationship and communication factors. Aims: This study aims to test the relationship between the theoretical antecedents of MNC and their impact on MNC. Design: A quantitative cross‐sectional study. Methods: The Austrian version of the revised MISSCARE Survey was completed by nurses working in general hospital units between May and July 2021. Recruitment followed a respondent‐driven sample via Austrian nursing education institutions and social media. One thousand six nurses fulfilled inclusion criteria. The structure of the theoretical constructs of the MNC model was tested using a confirmatory factor analysis approach. The relationships between the four antecedents and MNC were explored using structural equation modelling with 427 complete cases. Results: The results support the structural validity of the revised MISSCARE Austria concerning the defined theoretical constructs, although discriminant validity and measurement error should be further investigated. The antecedent "resource allocation: labor" had a statistically significant impact on MNC: The lack of adequate nursing staff played the most important role to explain missed care in our model. Conclusion: In our study in Austria, MNC was mostly influenced by a lack of appropriate labor resources. Further studies exploring mediation effects and non‐linear relationships may contribute to better understanding of reasons for MNC. Patient or Public Contribution: No patient or public contribution.
