Older Adults' Perspectives on Screening for Cognitive Impairment Following Critical Illness: Pre-Implementation Qualitative Study.

Screening for cognitive impairment following ICU discharge is recommended but not part of routine care. We sought to understand older adults' perspectives on screening for cognitive impairment following an ICU admission to inform the design and delivery of a cognitive screening intervention. DESIGN: Qualitative study using semi-structured interviews. SUBJECTS: Adults 60 years and older within 3 months of discharge from an ICU in an academic health system. INTERVENTIONS: Interviews were conducted via telephone, audio recorded and transcribed verbatim. All transcripts were coded in duplicate. Discrepancies were resolved by consensus. Codes were organized into themes and subthemes inductively. MEASUREMENTS AND MAIN RESULTS: We completed 22 interviews. The mean age of participants was 71 ± 6 years, 14 (63.6%) were men, 16 (72.7%) were White, and 6 (27.3%) were Black. Thematic analysis was organized around four themes: 1) receptivity to screening, 2) communication preferences, 3) information needs, and 4) provider involvement. Most participants were receptive to cognitive screening; this was influenced by trust in their providers and prior experience with cognitive screening and impairment. Participants preferred simple, direct, compassionate communication. They wanted to understand the screening procedure, the rationale for screening, and expectations for recovery. Participants desired input from their primary care provider to have their cognitive screening results placed in the context of their overall health, because they had a trusted relationship, and for convenience. CONCLUSIONS: Participants demonstrated limited understanding of and exposure to cognitive screening but see it as potentially beneficial following an ICU stay. Providers should use simple, straightforward language and place emphasis on expectations. Resources may be needed to assist primary care providers with capacity to provide cognitive screening and interpret results for ICU survivors. Implementation strategies can include educational materials for clinicians and patients on rationale for screening and recovery expectations.

Defining Optimal Head-Tilt Position of Resuscitation in Neonates and Young Infants Using Magnetic Resonance Imaging Data.

Head-tilt maneuver assists with achieving airway patency during resuscitation. However, the relationship between angle of head-tilt and airway patency has not been defined. Our objective was to define an optimal head-tilt position for airway patency in neonates (age: 0-28 days) and young infants (age: 29 days-4 months). We performed a retrospective study of head and neck magnetic resonance imaging (MRI) of neonates and infants to define the angle of head-tilt for airway patency. We excluded those with an artificial airway or an airway malformation. We defined head-tilt angle a priori as the angle between occipito-ophisthion line and ophisthion-C7 spinous process line on the sagittal MR images. We evaluated medical records for Hypoxic Ischemic Encephalopathy (HIE) and exposure to sedation during MRI. We analyzed MRI of head and neck regions of 63 children (53 neonates and 10 young infants). Of these 63 children, 17 had evidence of airway obstruction and 46 had a patent airway on MRI. Also, 16/63 had underlying HIE and 47/63 newborn infants had exposure to sedative medications during MRI. In spontaneously breathing and neurologically depressed newborn infants, the head-tilt angle (median ± SD) associated with patent airway (125.3° ± 11.9°) was significantly different from that of blocked airway (108.2° ± 17.1°) (Mann Whitney U-test, p = 0.0045). The logistic regression analysis showed that the proportion of patent airways progressively increased with an increasing head-tilt angle, with > 95% probability of a patent airway at head-tilt angle 144-150°.

Assessment of upper airway patency in spontaneously breathing non-intubated neonates and infants undergoing conventional MRI of head and neck.

PURPOSE: Neonates and infants frequently undergo MRI examinations of the brain or head and neck in spontaneous respiration. This study aims to evaluate the patency of the upper airway and associated risk factors in spontaneously breathing neonates and infants undergoing MRI of head and neck. METHODS: Airway patency was assessed on sagittal and axial MRI images of the head and neck region for neonates and infants retrospectively. Anteroposterior diameters were measured at the soft palate and tongue levels as well as a lateral diameter at the tongue level for the patent airway. Chart review for risk factors was carried out. RESULTS: A total of 831 children between 0 and 12 months of age had an MRI. Eighty-two children with spontaneous ventilation were included. The airway was occluded in 29/82 (35%) of children. Twenty-four out of 29 (83%) children with airway occlusion had a depressed level of consciousness, 7/24 (29%) of whom were sedated with a single dose of benzodiazepine and 17/24 (71%) were on anti-epileptic therapy for an underlying seizure disorder and/or hypoxic ischemic encephalopathy. Forty-three out of 82 (65%) of children had an open airway. The airway diameters (mean ± SD) were 5.9 ± 2 mm (anteroposterior (AP) at soft palate), 7.4 ± 2.9 mm (lateral at soft palate), and 6.3 mm ± 1.6 (AP at dorsum of tongue). CONCLUSION: A significant proportion of spontaneously breathing neonates and infants with hypoxic ischemic encephalopathy or sedation show evidence of airway obstruction during MRI. Careful pre-MRI screening for decision of spontaneous breathing versus artificial airway support during MRI and robust airway monitoring during MRI are required for these vulnerable children.
