In December, two nearby hospitals, one almost 40 miles away, the other 60 miles away, closed their doors for good. The closings were the latest in a trend that has seen 21 rural hospitals across Texas shuttered in the past six years, leaving 160 still operating.Lyle, who is CEO, can’t help wondering whether his Falls Community Hospital will be next.“Most assuredly,” he replied when asked whether he could envision his central Texas hospital going under. “We’re not using our reserves yet, but I can see them from here.”It’s not just Texas: Nearly a hundred rural hospitals in the United States have closed since 2010, according to the Center for Health Services Research at UNC Chapel Hill. Another 600-plus rural hospitals are at risk of closing, according to an oft-cited 2016 report by iVantage Health Analytics. Texas had the most hospitals in danger of closing (75), the health metrics firm said. And Mississippi had the largest share of hospitals at risk (79 percent).Neither state has expanded Medicaid eligibility to more of its low-income residents under the Affordable Care Act, also known as Obamacare. In fact, the closures and at-risk hospitals are heavily clustered in the 14 states that have not expanded.Those state decisions not to expand have deprived rural hospitals, which already operate with the slimmest of margins, of resources that could be the difference between survival and closure.
