Objective To explore the best time period of pulse oximetry in congenital heart disease (CHD) screening. Methods Totally 5433 newborns delivered or treated in Ningbo Women and Children’s hospital were enrolled in the study. Cardiac color ultrasound was used to arrive diagnosis and every screening time period (0?~?24 h、24 h?~?48 h、48 h?~?72 h) was analysed. Results Among the three time periods: the sensibility was in the range of 54.72%?~?67.92%, specificity was 99.11%?~?99.61%, false negative rate was 32.08%?~?43.40%, false positive rate was 0.39%?~?0.89%, Youden index was 0.54?~?0.68, coincidence rate was 98.67?~?99.30, and kappa was 0.44?~?0.65. Conclusion The best screening time is the period between 48h and 72 h after birth.

Objective To evaluate the effectiveness of Chronic Care Model in hypertension management in community health services.Methods Three hundred patients diagnosed with hypertension participated in this study and were divided into intervention and control groups.In the following 9 months,intervention measures based on the Chronic Care Model were delivered to intervention group,while the conventional measures to control group.Data collected before and after the intervention were analyzed uuing descriptive statistics,t-test,x2-test and analysis of covariance by SPSS16.0 for Windows.Results The intervention group had statistically significant positive effectiveness in drinking habit,daily salt intake(decreased 0.78g),diastolic blood pressure (decreased 2mmHg),BMI(decreased 0.4) and SF-36 physical component summary score(decreased 1.7)(P＜0.05).The intervention group had better improvement in BMI and SF-36 physical component summry score than the control group.Conclusion The health outcomes of patients with hypertension could be improved by applying the Chronic Care Model featured diet,exercise habits and other health related factors management.
