Learning and Attention Deficit/Hyperactivity Disorders as Risk Factors for Prolonged Concussion Recovery in Children and Adolescents.

OBJECTIVE: Examine pre-existing learning disorders (LD) and attention deficit/hyperactivity disorders (ADHD) as risk factors for prolonged recovery and increased symptomology following pediatric mild traumatic brain injury (mTBI). METHODS: We conducted a retrospective cohort study of children/adolescents (5-17 years) with mTBI who presented to a Children's Minnesota Concussion Clinic between April 2018 and March 2019. Differences across strata of pre-existing conditions (present vs. absent) in time to recovery measures were estimated via Kaplan-Meier and Cox proportional hazards analyses and differences in symptom trajectories were examined via linear mixed-effects regression models. Regression models were adjusted for age, sex and other confounders. RESULTS: In our cohort of 680 mTBI patients, those with LD (n = 70) or ADHD (n = 107) experienced significantly longer median durations of symptoms (58 and 68 days, respectively) than those without (43 days). Accordingly, LD was significantly associated with delayed symptom recovery (adjusted hazard ratio (aHR) = 1.63, 95% CI: 1.16-2.29), return to school (1.47, 1.08-2.00), and return to physical activity (1.50, 1.10-2.04). Likewise, ADHD was associated with delayed recovery (1.69, 1.28-2.23), return to school (1.52, 1.17-1.97) and physical activity (1.55, 1.19-2.01). Further, patients with LD or ADHD reported, on average, significantly more concussion symptoms and higher vision symptom scores throughout recovery versus those without. There was no evidence that concussion or vision symptom recovery trajectories varied over time between those with/without LD or ADHD (joint P-interactions > 0.05). CONCLUSION: Pre-existing LD and ADHD are risk factors for prolonged and more symptomatic mTBI recovery in youth. These results can inform clinical concussion management and recovery expectations.

Concussion symptomology and recovery in children and adolescents with pre-existing anxiety.

OBJECTIVE: To examine pre-existing anxiety disorders as a risk factor for increased concussion symptomology and prolonged recovery in children and adolescents. METHODS: In this retrospective cohort study, we abstracted medical record data for 637 children/adolescents (5-17 years) presenting to three tertiary concussion clinics between April 2018 and March 2019. Primary outcomes were mean concussion symptom and vision symptom severity scores measured at clinic visits. Linear mixed-effects regression models were employed to investigate differences in average symptom load, vision symptom score and symptom recovery trajectories across anxiety strata, adjusted for random effects (time), age and sex. Secondary outcomes, time to concussion symptom recovery and time to return to academics and sports, respectively, were examined via log-rank tests and multivariable Cox regression. RESULTS: Among 637 eligible concussion patients, 155 (24%) reported pre-existing anxiety. On average, patients with anxiety reported an additional 2.64 (95% CI 1.84 to 3.44) concussion symptoms and 7.45 (95% CI 5.22 to 9.68) higher vision symptom severity scores throughout recovery versus those without, after adjusting for age and sex. There was no evidence that concussion or vision symptom trajectories varied over time between those with/without anxiety after accounting for baseline dissimilarities in symptom scores (all pinteraction >0.05). Anxiety was significantly associated with delayed symptom recovery (adjusted HR 3.34, 95% CI 2.18 to 5.12), return to school (adjusted HR 2.01, 95% CI 1.59 to 2.53) and return to physical activity (adjusted HR 1.88, 95% CI 1.49 to 2.37). CONCLUSIONS: Pre-existing anxiety disorders were associated with more severe symptomology and prolonged recovery after concussion in children and adolescents. These results can be referenced by providers to manage patients' recovery expectations.

Postpartum Nurses' Experience Caring for Infants With Neonatal Abstinence Syndrome.

OBJECTIVES: In previous years, otherwise healthy infants with neonatal abstinence syndrome (NAS) in our hospital were transferred to the NICU and frequently treated with medication. Currently, infants with NAS room-in with their mothers and rarely require medication. We sought to understand the lived experience of nurses on maternity and well-newborn units caring for infants with NAS. METHODS: We conducted focus groups of registered nurses on postpartum units at 2 hospitals using qualitative methodology. Themes were identified through consensus, and the focus groups were stopped when no new themes were identified. RESULTS: Seventeen postpartum nurses participated in 5 focus groups. The following major themes emerged: (1) managing the expectations of parents of newborns with NAS, (2) current NAS protocol (positive aspects of rooming-in and challenges with withdrawal scoring tool), (3) inconsistencies in care and communication, (4) perceived increase in nursing workload on the postpartum unit, and (5) nurses' emotional response to the care of infants with NAS. CONCLUSIONS: We highlight the perspectives of nursing staff on the well-newborn unit who were previously unaccustomed to caring for infants with NAS. With increasing numbers of infants with NAS and longer stays on the well-newborn unit, hospitals must prepare to better support staff and implement protocols that offer consistency in practice.
