Abstract:

Objective We systematically analyzed and compared the relevant studies on risk prediction models for diabetic foot,so as to provide references for nursing practice. Methods We searched PubMed,Embase,Web of Science,Cochrane Library,CBM,CNKI,Wanfang Data from the inception to March 1,2020,in order to collect studies on risk prediction models for diabetic foot. 2 researchers independently screened the literature,extracted information,and assessed the risk of bias and applicability concerns of the included literature by the prediction model risk of bias assessment tool. Results The search identified 7 relevant studies,including 6 development studies and 1 verification study. The area under the curve of 7 models was 0.65~0.88. The presence of monofilament insensitivity was the most commonly reported predictive factor of diabetic foot among all included models. All included studies have low concerns regarding applicability,but with a certain bias,which mostly due to the absence or non-reported of the blind method,the insufficient number of events per variable,omitting samples with missing data,the lack of model performance assessment and overfitting. Conclusion The research on risk prediction models for diabetic foot is still in the development stage. In the future,prediction models with good performance and low risk of bias should be developed and verified internally or externally.
