Telemedicine service may expand access to acute medical care, study finds

Mon, 03/02/2014 - 10:18pm
Interest has grown in telemedicine programs because of a shortage of primary care providers that is likely to become worse as more Americans acquire medical coverage under the Affordable Care Act. The first assessment of a large telemedicine program finds that patients use such services for a wide assortment of acute medical problems such as respiratory illnesses and skin problems. In addition, researchers found little evidence of misdiagnosis or treatment failure among those treated.

Pesticides increase risk for Parkinson's disease: Certain people may be more susceptible

Mon, 03/02/2014 - 9:34pm
Previous studies have shown the certain pesticides can increase the risk for developing Parkinson’s disease. Now, researchers have now found that the strength of that risk depends on an individual’s genetic makeup, which in the most pesticide-exposed populations could increase the chances of developing the debilitating disease by two- to six-fold.

Hypertensive patients' use of specialty services changed with primary care resdesign

Mon, 03/02/2014 - 8:52pm
Researchers studied how patients with treated hypertension used outpatient specialty care before, during, and after a primary-care redesign was spread system-wide. Patients with hypertension and few other conditions had 27-28 percent fewer specialty visits in each of the three years after redesign implementation started, compared to beforehand. Those with some other illnesses had 9 percent fewer specialty visits during medical home implementation and 5 percent fewer specialty visits during the following year.
