Most children with simple febrile seizures (SFSs) can be safely managed without lumbar puncture or other diagnostic tests without risking delayed diagnosis of bacterial meningitis, new data gathered from a 15-year span suggest.
Vidya R. Raghavan, MD, with the division of emergency medicine at Boston Children’s Hospital and Harvard Medical School, also in Boston, published their findings in Pediatrics.
In 2011, researchers published the American Academy of Pediatrics simple febrile seizure guideline, which recommends limiting lumbar puncture to non–low-risk patients. The guidelines also specified that neuroimaging and hematologic testing are not routinely recommended.
Dr. Raghavan and coauthors studied evaluation and management trends of the patients before and after the guidelines. They identified 142,121 children diagnosed with SFS who presented to 1 of 49 pediatric tertiary EDs and met other study criteria. Changes in management of SFS had started years before the guideline and positive effects continued after the guideline publication.
Researchers found a significant 95% decline in rates of lumbar puncture between 2005 and 2019 from 11.6% (95% confidence interval, 10.8%-12.4%) of children in 2005 to 0.6% (95% CI, 0.5%-0.8%; P < .001) in 2019. The most significant declines were among infants 6 months to 1 year.
“We found similar declines in rates of diagnostic laboratory and radiologic testing, intravenous antibiotic administration, hospitalization, and costs,” the authors wrote.
“Importantly,” they wrote, “the decrease in testing was not associated with a concurrent increase in delayed diagnoses of bacterial meningitis.”
The number of hospital admissions and total costs also dropped significantly over the 15-year span of the study. After adjusting for inflation, the authors wrote, costs dropped from an average $1,523 in 2005 to $605 (P < .001) in 2019.
Among first-time presentations for SFSs, 19.2% (95% CI, 18.3%-20.2%) resulted in admission in 2005. That rate dropped to 5.2% (95% CI, 4.8%-5.6%) in 2019 (P < .001), although the authors noted that trend largely plateaued after the guideline was published.
“Our findings are consistent with smaller studies published before 2011 in which researchers found declining rates of LP [lumbar puncture] in children presenting to the ED with their first SFS,” the authors wrote.
Mercedes Blackstone, MD, an emergency physician at the Children’s Hospital of Philadelphia, said in an interview that the paper offers reassurance for changed practice over the last decade.
She said there was substantial relief in pediatrics when the 2011 guidelines recognized formally that protocols were outdated, especially as bacterial meningitis had become increasingly rare with widespread use of pneumococcal and Haemophilus influenzae vaccines. Practitioners had already started to limit the spinal taps on their own.
“We were not really complying with the prior recommendation to do a spinal tap in all those children because it often felt like doing a pretty invasive procedure with a very low yield in what was often a very well child in front of you,” she said.
In 2007, the authors noted, a few years before the guidelines, rates of bacterial meningitis had decreased to 7 per 100,000 in children aged between 2 and 23 months and 0.56 per 100,000 in children aged between 2 and 10 years.
However, Dr. Blackstone said, there was still a worry among some practitioners that there could be missed cases of bacterial meningitis.
“It’s very helpful to see that in all those years, the guidelines have been very validated and there were really no missed cases,” said Dr. Blackstone, author of CHOP’s febrile seizures clinical pathway.
It was good to see the number of CT scans drop as well, she said. Dr. Raghavan’s team found they decreased from 10.6% to 1.6%; P < .001, over the study period.
“Earlier work had shown that there was still a fair amount of head CTs happening and that’s radiation to the young brain,” Dr. Blackstone noted. “This is great news.”
Dr. Blackstone said it was great to see so many children from so many children’s hospitals included in the study.
The paper confirmed that “we’ve reduced a lot of unnecessary testing, saved a lot of cost, and had no increased risk to the patients,” she said.
Dr. Blackstone pointed out that the authors include a limitation that many children are seen in nonpediatric centers in community adult ED and she said those settings tend to have more testing.
“Hopefully, these guidelines have penetrated into the whole community,” she said. “With this paper they should feel reassured that they can spare children some of these tests and procedures.”
Dr. Raghavan and Dr. Blackstone declared no relevant financial relationships.
