Hadassah Team Develops New Model Which May Save Women Unnecessary Interventions


Dr. Carolyn F. Weiniger

A study team led by Dr. Carolyn F. Weiniger, an obstetrical anesthesiologist at the Hadassah University Medical Center, has developed a new model for identifying placenta accreta, the abnormal implantation of the placenta into the uterine wall.

The team reviewed data from 46,623 women who had their babies at Hadassah over a nine-year period. The predictive model they created is based on three clinical factors, which would be assessed if a woman was suspected of having a possible placenta accreta:

• the presence of placenta previa
• the number of previous cesarean deliveries and
• ultrasound suspicion of accreta

At a "maximal-sensitivity cut-off," the model identified 100 percent of the women who had been confirmed to have the condition.

The data derived from this model may spare some women unnecessary interventions, such as general anesthesia, placement of large-bore intravenous lines, and elective hysterectomy.

Dr. Weiniger presented her model at the annual meeting of the Society for Obstetric Anesthesia and Perinatology. Read the entire article in Ob. Gyn. News.

Hadasit, Hadassah’s Technology Transfer Arm, Reviews 2012’s Accomplishments

When the Hadassah University Medical Center’s physicians suggest a solution to a medical problem which can lead to the development of a new medicine or product, Hadasit, Hadassah’s technology transfer arm, explores its feasibility and supports the promotion of those viable ideas with innovation potential. Although 2012 has been “a year full of challenges for the life science industry,” says Einat Zisman, Hadasit’s Chief Executive Officer, Hadasit still signed 125 agreements for clinical trials, all to be done at Hadassah. In addition, Hadasit signed 15 agreements for cooperation and commercialization of technologies that were developed at Hadassah. Click here to read the latest Newsletter from Hadasit >>
