Nationwide study shows integrated health systems yield marginal increases in quality of care with higher costs for medical services, compared with care delivered by independent hospitals and physician practices. Proponents of health system mergers have argued that consolidation brings higher value care.
Researchers have known people who live farther from the equator are more likely to develop multiple sclerosis (MS) and have often attributed that to vitamin D exposure. But countries farther from the equator are also more likely to be wealthier than countries nearer to the equator. A new analysis shows that the amount a country spends on health care may help explain the link between MS and latitude. This new research is published in the August 24, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.
