Great saphenous vein (GSV) incompetence is the most common cause of superficial venous insufficiency. Radiofrequency catheter ablation (RFA) is superior to conventional ligation and stripping, and endovenous laser treatment (EVL) has emerged as an effective alternative to RFA. This randomized study evaluated RFA and EVL for superficial venous insuf...
The goal was to assess the impact of universal bilirubin screening on severe hyperbilirubinemia and phototherapy use.
In this retrospective cohort study of 358086 infants of > or =35 weeks and > or =2000 g born between January 1, 1995, and June 30, 2007, we obtained demographic data, bilirubin levels, and codes for inpatient phototherapy from exist...
We evaluated antenatal ultrasound (U/S) exposure as a risk factor for autism spectrum disorders (ASD), comparing affected singleton children and control children born 1995–1999 and enrolled in the Kaiser Permanente health care system. Among children with ASD (n = 362) and controls (n = 393), 13% had no antenatal exposure to U/S examinations; case–c...
Our aims were to estimate the efficacy of hospital phototherapy for neonatal jaundice and the number needed to treat to prevent one infant from reaching the exchange transfusion level.
From a cohort of 281 898 infants weighing > or =2000 g born at > or =35 weeks' gestation at 12 Northern California Kaiser hospitals from 1995 to 2004, we identified ...
To quantify the relationship between recurrent wheezing (RW) in the third year of life and respiratory syncytial virus (RSV) infection, prematurity, and neonatal oxygen exposure.
Retrospective cohort study linking inpatient, outpatient, and laboratory databases for cohort assembly and logistic regression analysis.
Integrated health care delivery sy...
ronchiolitis has the highest incidence rate of any lower respiratory infection among infants and children <2 years of age. Respiratory syncytial virus (RSV) is the most common etiology of bronchiolitis. The American Academy of Pediatrics does not recommend routine RSV testing for infants and children with bronchiolitis. The clinical predictors of R...
Existing intensive care unit (ICU) mortality measurement systems address in-hospital mortality only. However, early postdischarge mortality contributes significantly to overall 30-day mortality. Factors associated with early postdischarge mortality are unknown.
We performed a retrospective study of 8484 ICU patients. Our primary outcome was early ...
Federal and state agencies are considering ICU performance assessment and public reporting; however, an accurate method for measuring performance must be selected. In this study, we determine whether a substantial variation in ICU mortality performance still exists in modern ICUs, and compare the predictive accuracy, reliability, and data burden of...
