ABSTRACT
Objective To investigate the significance of procalcitonin(PCT),C-reactive protein (CRP)and WBC counts in predicting the postoperative jnfections in patients with bone fractures.Methods Clinical data of 49 patients with open fractures were retrospectively analyzed,and the patients were grouped into the infeeted(n=24)and non.infected(n=25).PCT,CRP and WBC values were detected 1,4,7and 10 days after the operations,and the results were compared with those taken from the healthy controls.Areas under the receiver operating characteristic(ROC)curves were used to determine the value in predicting postoperative infections.Results PCT,CRP and WBC values in the infected group and the noninfected group were higher than those in health controls(F=19.84,57.71 and 35.44,P＜0.01).PCT,CRP and WBC values in the infected group were higher than those in the non-infected group 4.7 and 10 days after the operations(tPCT=7.31,7.74 and 4.59;tCRP=2.23,5.75 and 8.01;tWBC=2.34,2.51 and 4.07,P＜0.05).ROC curves suggested that PCT value was more sensitive and had higher specificity than CRP and WBC values in the diagnosis of postoperative infections.Conclusions PCT,CRP and WBC values arise in bone fracture patients with postoperative infections.Detection of PCT has higher sensitivity and specificity.which can be used in early diagnosis of postoperative infections.
ABSTRACT
Objective To explore the development trends in community nursing. Methods The current situation of community nursing in Shanghai was analyzed by means of questionnaire surveys and literature review. Subjects A total of 3 173 questionnaires were distributed to community nurses, hospital nurses, community residents, and hospitalized patients and 2 942 of them were retrieved, the rate of retrieval being 93.8%. Results The demand for community nursing was not satisfied, the number of community nurses was insufficient and their general quality was low. Conclusion The scope of services in community nursing needs to be expanded with demand as a guide, more community nurses need to be cultivated, and the quality of the nursing contingent needs to be enhanced.
