Dedicated Afternoon Rounds for ICU Patients' Families and Family Satisfaction With Care.

OBJECTIVE: It was hypothesized that adding dedicated afternoon rounds for patients' families to supplement standard family support would improve overall family satisfaction with care in a neuroscience ICU. DESIGN: Pre- and postimplementation (pre-I and post-I) design. SETTING: Single academic neuroscience ICU. PATIENTS: Patients in the neuroscience ICU admitted for longer than 72 hours or made comfort measures only at any point during neuroscience ICU admission. INTERVENTION: The on-service attending intensivist and a neuroscience ICU nursing leader made bedside visits to families to address concerns during regularly scheduled, advertised times two afternoons each week. MEASUREMENTS AND MAIN RESULTS: One family member per patient during the pre-I and post-I periods was recruited to complete the Family Satisfaction in the ICU 24 instrument. Post-I respondents indicated whether they had participated in the afternoon rounds. For primary outcome, the mean pre-I and post-I composite Family Satisfaction in the ICU 24 scores (on a 100-point scale) were compared. A total of 146 pre-I (March 2013 to October 2014; capture rate, 51.6%) and 141 post-I surveys (October 2014 to December 2015; 47.2%) were collected. There was no difference in mean Family Satisfaction in the ICU 24 score between groups (pre-I, 89.2 ± 11.2; post-I, 87.4 ± 14.2; p = 0.6). In a secondary analysis, there was also no difference in mean Family Satisfaction in the ICU 24 score between the pre-I respondents and the 39.0% of post-I respondents who participated in family rounds. The mean Family Satisfaction in the ICU 24 score of the post-I respondents who reported no participation trended lower than the mean pre-I score, with fewer respondents in this group reporting complete satisfaction with emotional support (75% vs. 54%; p = 0.002), coordination of care (82% vs. 68%; p = 0.03), and frequency of communication by physicians (60% vs. 43%; p = 0.03). CONCLUSIONS: Dedicated afternoon rounds for families twice a week may not necessarily improve an ICU's overall family satisfaction. Increased dissatisfaction among families who do not or cannot participate is possible.

Methodology for Low-Field, Portable Magnetic Resonance Neuroimaging at the Bedside.

Neuroimaging is a critical component of triage and treatment for patients who present with neuropathology. Magnetic resonance imaging and non-contrast computed tomography are the gold standard for diagnosis and prognostication of patients with acute brain injuries. However, these modalities require intra-hospital transport to strict, access-controlled environments, which puts critically ill patients at risk for complications and secondary injuries. A novel, portable MRI (pMRI) device that can be deployed at the patient's bedside provides a needed solution. In a dual-center investigation, Yale New Haven Hospital has obtained regular neuroimaging on patients using the pMRI as part of routine clinical care in the Emergency Department and Intensive Care Unit (ICU) since August of 2020. Massachusetts General Hospital has begun using pMRI in the Neuroscience Intensive Care Unit since January 2021. This technology has expanded the population of patients who can receive MRI imaging by increasing accessibility and timeliness for scan completion by eliminating the need for transport and increasing the potential for serial monitoring. Here we describe our methods for screening, coordinating, and executing pMRI exams and provide further detail on how to scan specific patient populations.

Portable, bedside, low-field magnetic resonance imaging for evaluation of intracerebral hemorrhage.

Radiological examination of the brain is a critical determinant of stroke care pathways. Accessible neuroimaging is essential to detect the presence of intracerebral hemorrhage (ICH). Conventional magnetic resonance imaging (MRI) operates at high magnetic field strength (1.5-3 T), which requires an access-controlled environment, rendering MRI often inaccessible. We demonstrate the use of a low-field MRI (0.064 T) for ICH evaluation. Patients were imaged using conventional neuroimaging (non-contrast computerized tomography (CT) or 1.5/3 T MRI) and portable MRI (pMRI) at Yale New Haven Hospital from July 2018 to November 2020. Two board-certified neuroradiologists evaluated a total of 144 pMRI examinations (56 ICH, 48 acute ischemic stroke, 40 healthy controls) and one ICH imaging core lab researcher reviewed the cases of disagreement. Raters correctly detected ICH in 45 of 56 cases (80.4% sensitivity, 95%CI: [0.68-0.90]). Blood-negative cases were correctly identified in 85 of 88 cases (96.6% specificity, 95%CI: [0.90-0.99]). Manually segmented hematoma volumes and ABC/2 estimated volumes on pMRI correlate with conventional imaging volumes (ICC = 0.955, p = 1.69e-30 and ICC = 0.875, p = 1.66e-8, respectively). Hematoma volumes measured on pMRI correlate with NIH stroke scale (NIHSS) and clinical outcome (mRS) at discharge for manual and ABC/2 volumes. Low-field pMRI may be useful in bringing advanced MRI technology to resource-limited settings.
