Texas is over-reporting some of its maternal mortality data, a national study released today found.
The study, from the University of Maryland Population Research Center and , is a follow-up to a study released in August 2016 that found the maternal mortality rate in Texas had .
Eugene Declercq, a professor at Boston University School of Public Health, says he and other researchers didn鈥檛 include Texas in their calculation of a national maternal mortality rate at that time because the data looked so unusual.
鈥淭he jump in Texas was so pronounced and so quick that we thought there was probably some kind of data anomaly at the heart of it,鈥� Declercq says. 鈥淵ou only see this kind of thing in disasters.鈥�
After finishing the 2016 study, the same researchers 鈥� Declercq, Marian MacDorman and Maria Thoma 鈥� focused specifically on Texas to try to figure out why the numbers were so high.
The new study compares two periods of Texas鈥� maternal mortality data. Researchers looked at women who died while pregnant or shortly after giving birth between 2006 and 2010 and between 2011 and 2015.
They found an 87 percent spike in rates between those two periods.
MacDorman, a research professor at the University of Maryland Population Research Center, says when they looked closer they found that some of the spike could be because of over-reporting.
鈥淭he observed increase in maternal mortality in Texas from 2006-2010 to 2011-2015 is likely a result of both a true increase in rates and increased over-reporting of maternal deaths, as indicated by implausibly high and increasing rates for women aged 鈮�40 years and among nonspecific causes of death,鈥� the authors wrote in the study.
This highlights two "public health emergencies鈥� in Texas, MacDorman says.
鈥淥ne is a sharp increase in the maternal mortality rate in recent years,鈥� she says, 鈥渁nd two, a lack of reliable data to better characterize and further understand the increase.鈥�
MacDorman says the rise in nonspecific death data is not helpful to anyone who wants to use the data to prevent future deaths.
鈥淵ou don鈥檛 know if the women are dying because of hemorrhage after the birth, or opioid addiction or high blood pressure,鈥� MacDorman says. 鈥淵ou don鈥檛 know what鈥檚 going on, so you can鈥檛 design a program to prevent those deaths.鈥�
Even though some of the data are unreliable, researchers say, that doesn鈥檛 mean Texas doesn鈥檛 have a serious problem.
鈥淭here [are] two ways you can look at this: You could rationalize it and say, 'Well, we really don鈥檛 have a problem; it鈥檚 a data issue,鈥� Declercq says. 鈥淏ut the fact of the matter is, even the most conservative look at the data from Texas suggests that it鈥檚 an outlier within the country.鈥�
The other way to look at this is that 鈥渘ot having a functional public health system that can report this accurately is a problem in and of itself,鈥� he says.
Both Declercq and MacDorman say the state needs to create a fully staffed review committee and hire someone dedicated to combing through and double-checking death certificate data before it gets to that committee.
Dr. Lisa Hollier, who leads the Texas鈥� Maternal Mortality and Morbidity Task Force, says she鈥檚 not surprised by the study; she鈥檚 seen evidence of both over-reporting in some areas and under-reporting in others.
Hollier also says that the state should consider having a dedicated review committee.
鈥淭hose reviews can provide a mechanism to review and access for over-reporting and under-reporting by determining which deaths are truly maternal deaths,鈥� she says.
Last year, state lawmakers passed a law to improve the evaluation of deaths in the state, as well as improve how death certificates are filled out. Lawmakers also set aside money to make sure the maternal death box is checked correctly on death certificates.
Hollier says those efforts should help make sure Texas has more reliable data in the future.
