Résumé
OBJECTIVE:To evaluate the content validity and interrater reliability of the modified medication discrepancy tool (MDT). METHODS:According to the structure of MDT(English edition),the terms of MDT were modified,and 5 invited ex-perts used content validity indicator to test the content validity of MDT. The interrater reliability method was adopted to test the reli-ability of MDT. The interrater reliability was performed by 2 evaluators to same 20 research objects with modified MDT. RE-SULTS:Average item-level content validity index was over 0.800,and scale-level content validity index was 0.970. The item-level interrater reliability was between 0.667 and 1.000(P<0.01). The scale-level interrater reliability was 0.840(P<0.01). CONCLU-SIONS:The modified MDT has good content validity and interrater reliability,and can be used to evaluate discharged medication discrepancies in China.
Résumé
Background:Because of its non-invasiveness,direct inspection,and high detection rate,capsule endoscopy(CE) has been accepted as the first-line examination for diagnosis of obscure gastrointestinal bleeding(OGIB). However,no matter the result of CE is positive or negative,it is unable to accurately predict the occurrence of rebleeding. Aims:To preliminarily investigate the related risk factors of rebleeding in OGIB patients with positive or negative CE for reducing the rebleeding rate. Methods:One hundred and sixteen OGIB patients undergone CE and with follow-up data from October 2009 to October 2013 at the First Affiliated Hospital of Soochow University were recruited,the rebleeding rate of patients with positive and negative CE,and the risk factors of rebleeding were analyzed. Results:CE diagnostic rate was 56. 9% , and the overall rebleeding rate was 37. 9% . The rebleeding rate in CE positive patients was significantly higher than that in CE negative patients(48. 5% vs. 24. 0% ,P < 0. 01). Male,age ≥50 years,hypertension,accumulated bleeding ≥500 mL within 3 months before CE were the independent risk factors of increase in rebleeding rate in CE positive patients. Age≥50 years,abnormal blood coagulation,without specific treatment were the independent risk factors of increase in rebleeding rate in CE negative patients. Conclusions:Followed-up should be performed in OGIB patients with risk factors of rebleeding for at least 24 months after CE. Repeated examination can be avoided in OGIB patients without risk factors.
