Intervention Description: The intervention in the study involved the use of a natural language processing (NLP)-based clinical decision support system embedded in the electronic health record (EHR) to identify potential surgical candidates among children with epilepsy. Patients identified as potential surgical candidates by the NLP were then randomized for their provider to receive an alert or no reminder prior to the patient's visit. The alerts were delivered through two modalities: half of the alerts were sent via email, and the other half were in-basket messages that appeared in the EHR. The primary aim of the intervention was to assess whether these automated alerts increased referrals for epilepsy surgery evaluations.
Intervention Results: Between April 2017 and April 2019, at total of 4858 children were screened by the system, and 284 (5.8%) were identified as potential surgical candidates. Two hundred four patients received an alert, and 96 patients received standard care. Median follow-up time was 24 months (range: 12-36 months). Compared to the control group, patients whose provider received an alert were more likely to be referred for a presurgical evaluation (3.1% vs 9.8%; adjusted hazard ratio [HR] = 3.21, 95% confidence interval [CI]: 0.95-10.8; one-sided p = .03). Nine patients (4.4%) in the alert group underwent epilepsy surgery, compared to none (0%) in the control group (one-sided p = .03).
Conclusion: Yes, the study reported statistically significant findings related to the impact of automated alerts on the referral patterns for epilepsy surgery evaluations. Specifically, the study found that providers were more likely to refer patients with epilepsy for a presurgical evaluation after receiving an automated alert. Furthermore, the study results indicated that the alerts significantly increased the likelihood of referral for presurgical evaluations, as evidenced by the statistical analysis using a Cox proportional hazards model to estimate the hazard ratio (HR) of referrals after receiving an alert and Wald's test to estimate the corresponding p-value. Additionally, the study reported statistically significant differences in the proportion of patients referred for presurgical evaluations and surgeries between the group that received alerts and the control group that did not receive alerts.
Study Design: The study design was a prospective, randomized controlled trial. The trial evaluated the effectiveness of a natural language processing (NLP)-based clinical decision support system embedded in the electronic health record (EHR) to increase referrals for epilepsy surgery evaluations. The study randomly assigned potential surgical candidates to either receive an automated alert or standard of care (no alert) prior to their scheduled visit. The primary outcome was referral for a neurosurgical evaluation, and the likelihood of referral was estimated using a Cox proportional hazards regression model. The study was conducted over a 2-year period, from April 16, 2017, to April 15, 2019.
Setting: The study was conducted at a large pediatric epilepsy center in Cincinnati, OH, USA, specifically at the Cincinnati Children's Hospital Medical Center (CCHMC). The providers involved in the study were attending neurologists and nurse practitioners from this center. The research was carried out at 14 pediatric neurology outpatient clinic sites affiliated with the hospital.
Population of Focus: The target audience for this study includes healthcare providers, particularly neurologists and nurse practitioners involved in the care of children with epilepsy. Additionally, researchers and professionals in the fields of medical informatics, natural language processing, and clinical decision support systems may also find this study relevant and valuable. Furthermore, healthcare administrators and policymakers interested in improving the utilization of referrals for epilepsy surgery evaluations, as well as those involved in the implementation of technology-based interventions in clinical practice, would benefit from the findings of this research.
Sample Size: The study included a total of 284 children with epilepsy who were identified as potential surgical candidates by the natural language processing (NLP) algorithm and were randomized 2:1 for their provider to receive an alert or standard of care (no alert). Of these, 96 patients were assigned to the control group, 93 whose treating provider received an email, and 95 whose treating provider received an EHR alert. The study was conducted over a 2-year period, from April 16, 2017, to April 15, 2019.
Age Range: The study does not focus on a specific age group. However, the patients included in the study were children with epilepsy who were being treated at Cincinnati Children's Hospital Medical Center. The age range of the patients is not specified in the article.
