An interactive nomogram to predict healthcare-associated infections in ICU patients: A multicenter study in GuiZhou Province, China.

ABSTRACT:

Objective

To develop and validate an interactive nomogram to predict healthcare-associated infections (HCAIs) in the intensive care unit (ICU).

Methods

A multicenter retrospective study was conducted to review 2017 data from six hospitals in Guizhou Province, China. A total of 1,782 ICU inpatients were divided into either a training set (n = 1,189) or a validation set (n = 593). The patients' demographic characteristics, basic clinical features from the previous admission, and their need for bacterial culture during the current admission were extracted from electronic medical records of the hospitals to predict HCAI. Univariate and multivariable analyses were used to identify independent risk factors of HCAI in the training set. The multivariable model's performance was evaluated in both the training set and the validation set, and an interactive nomogram was constructed according to multivariable regression model. Moreover, the interactive nomogram was used to predict the possibility of a patient developing an HCAI based on their prior admission data. Finally, the clinical usefulness of the interactive nomogram was estimated by decision analysis using the entire dataset.

Results

The nomogram model included factor development (local economic development levels), length of stay (LOS; days of hospital stay), fever (days of persistent fever), diabetes (history of diabetes), cancer (history of cancer) and culture (the need for bacterial culture). The model showed good calibration and discrimination in the training set [area under the curve (AUC), 0.871; 95% confidence interval (CI), 0.848-0.894] and in the validation set (AUC, 0.862; 95% CI, 0.829-0.895). The decision curve demonstrated the clinical usefulness of our interactive nomogram.

Conclusions

The developed interactive nomogram is a simple and practical instrument for quantifying the individual risk of HCAI and promptly identifying high-risk patients.

Project description:Objectives: To qualitatively compare the influence of different ownership which is considered as a kind of institutional environment in public hospitals, private hospitals, and mixed-ownership hospitals on hospital governance structure and organizational behavior. Design: Qualitative descriptive study, using semi-structured, in-depth interviews and thematic template analysis, theoretically informed by critical realism. Participants: 27 key informants including national policymakers in charge of the health sector, influential researchers, local administrators responsible for implementing policies, and hospital managers who are experienced in institutional change. Results: Hospital ownership has a significant influence on hospitals in terms of decision-making power allocation, residual ownership allocation, market entry level, accountability, and social functions. These five aspects in hospital organizational structure incentivize hospitals to adapt to the internal and external environment of the hospital organization-such as market environment, governance, and financing arrangements-affect the behavior of the hospital organization, and ultimately affect the efficiency of hospital operation and quality of service. The incentives under the public system are relatively distorted. Private hospitals have poor performance in failing their social functions due to their insufficient development ability. Compared to them, mixed ownership hospitals have a better performance in terms of incentive mechanism and organizational development. Conclusion: Public hospitals should improve the governance environment and decision-making structure, so as to balance their implementation of social functions and achieve favorable organizational development. For private hospitals, in addition to the optimization of the policy environment, attempts should be made to strengthen their supervision. The development of mixed-ownership hospitals should be oriented towards socialized governance.
