Our goal is to address the need for driver-state detection using wearable and in-vehicle sensor measurements of driver physiology and health. To address this goal, we deployed in-vehicle systems, wearable sensors, and procedures capable of quantifying real-world driving behavior and performance in at-risk drivers with insulin-dependent type 1 diabetes mellitus (DM). We applied these methodologies over 4 weeks of continuous observation to quantify differences in realworld driver behavior profiles associated with physiologic changes in drivers with DM (N=19) and without DM (N=14). Results showed that DM driver behavior changed as a function of glycemic state, particularly hypoglycemia. DM drivers often drive during at-risk physiologic states, possibly due to unawareness of impairment, which in turn may relate to blunted physiologic responses (measurable heart rate) to hypoglycemia after repeated episodes of hypoglycemia. We found that this DM driver cohort has an elevated risk of crashes and citations, which our results suggest is linked to the DM driver’s own momentary physiology. Overall, our findings demonstrate a clear link between at-risk driver physiology and real-world driving. By discovering key relationships between naturalistic driving and parameters of contemporaneous physiologic changes, like glucose control, this study directly advances the goal of driver-state detection through wearable physiologic sensors as well as efforts to develop “gold standard” metrics of driver safety and an individualized approach to driver health and wellness.

Purpose: Prefabricated arrays with a limited number of electrodes offer an opportunity to hasten the diagnosis of seizures; however, their accuracy to detect seizures is unknown. We examined the utility of two limited-montage EEG setups for the detection of nonconvulsive seizures. Methods: Thirty previously interpreted EEG segments with nonconvulsive seizures from 30 patients and 60 segments with background slowing or normal EEG from 60 patients were rendered in a bipolar “double banana” montage, a double distance “neonatal” montage, and a circumferential “hatband” montage. Experts reviewed 60 to 180 seconds long segments to determine whether seizures were present and if the EEG data provided were sufficient to make a decision on escalation of clinical care by ordering an additional EEG or prescribing anticonvulsants. The periodic patterns on the ictal-interictal continuum were specifically excluded for this analysis to keep the focus on definite electrographic seizures. Results: The sensitivities for seizure of the neonatal and hatband montages were 0.96 and 0.84, respectively, when compared with full montage EEG, whereas the specificities were 0.94 and 0.98, respectively. Appropriate escalation of care was suggested for 96% and 92% of occurrences of seizure patterns in neonatal and hatband montages, respectively. When compared with clinical EEG, the sensitivities of the neonatal and hatband montages for seizure diagnosis were 0.85 and 0.69, respectively. Conclusions: Nonconvulsive seizures were detected with high accuracy using the limited electrode array configuration in the neonatal and hatband montages. The sensitivity of the neonatal montage EEG in detecting seizures was superior to that of a hatband montage. These findings suggest that in some patients with nonconvulsive seizures, limited-montage EEG may allow to differentiate ictal and slow patterns.

Palliative care competencies at the pediatric resident training level expand learned knowledge into behavior. The objective of this study was to investigate mode of palliative care education delivery preferred by pediatric residents and to report on participatory approach to resident palliative care curriculum design. A one-hour monthly palliative care curriculum was designed and implemented in a participatory manner with 20 pediatric residents at a free-standing Midwestern children’s hospital. Outcome measures included pediatric residents’ personal attitude and perceived training environment receptivity before and after implementation of a palliative care competency-based curriculum. An 18-item survey utilizing Social Cognitive Theory Constructs was administered at baseline and after palliative care curriculum implementation (2017–2018 curricular year). Pediatric residents prioritized real case discussions in group format (16/20) over other learning formats. Topics of highest interest at baseline were: discussing prognosis and delivering bad news (weighted average 12.9), pain control (12.3), goals of care to include code status (11.1), and integrative therapies (10.7). Summary of ordinal responses revealed improvement in self-assessment of personal attitude toward palliative care and training environment receptivity to palliative care domains after year-long curriculum implementation. Curricular approach which is attentive to pediatric residents’ preferred learning format and self-assessment of their behaviors within their care setting environment may be beneficial in competency-based primary palliative training.
