HOUSTON—Children with infantile spasms commonly endure substantial delays in diagnosis and treatment, according to research presented at the 70th Annual Meeting of the American Epilepsy Society. “A simple lack of awareness of infantile spasms among healthcare providers may be responsible for potentially catastrophic delays in diagnosis and treatment,” said Shaun Hussain, MD, Director of the University of California, Los Angeles Infantile Spasms Program, and colleagues. “There is a desperate need for effective interventions to increase basic familiarity with infantile spasms among healthcare providers.”

Treatment delay among children with infantile spasms is associated with poor long-term developmental outcomes. Dr. Hussain and his colleagues performed a study to measure delays in diagnosis and treatment of infantile spasms and identify barriers to optimal care.
The researchers retrospectively identified children with video-EEG-confirmed infantile spasms in a clinical database. When the children’s parents presented for follow-up, they were surveyed about their experiences with diagnosis and treatment. The investigators asked about medical and sociodemographic factors that could affect the care of infantile spasms. Specifically, the researchers determined the dates of infantile spasms onset, first visit with any healthcare provider, first visit with any neurologist, and first visit with an effective provider. Dr. Hussain and colleagues defined an effective provider as a healthcare provider who identified infantile spasms and prescribed a first-line treatment (ie, ACTH, corticosteroids, vigabatrin, or surgical resection). The investigators reviewed medical records to corroborate parents’ survey responses. They calculated the time to first effective provider using Cox proportional hazards regression.
The parents of 100 children with previous or ongoing infantile spasms were included in the study. Approximately 29% of patients were seen by an effective provider within one week of spasms onset. The median time from spasms onset to the first visit with an effective provider was 24.5 days. In sequential univariate analyses, parental sociodemographic attributes (eg, race, ethnicity, religion, household income, education level, type of healthcare insurance, and distance from patients’ home to the tertiary center) did not predict time to first effective provider. In open-ended discussions, numerous parents reported that their suspicions that “something was wrong” often had been discounted by pediatricians, emergency room physicians, and neurologists. In a qualitative analysis, many parents reported self-diagnosis using Internet resources and self-referral after various diagnostic difficulties and false reassurance by healthcare providers.
“A delay in diagnosis can lead to treatment failure and increase the risk of intellectual disability, autism, lifelong epilepsy, and even death,” said Dr. Hussain. “Some of these children can be cured, but successful treatment often depends on prompt diagnosis. The delays we observed are simply horrifying and represent a failure of our healthcare system to address a preventable cause of mental retardation.”
