Characteristics And Outcomes Of Patients Discharged Directly Home From A Medical Intensive Care Unit, Michele Fiorella, Ms, Preeyal M. Patel, Ann Zheng, Lauren Mcdonnell, Msn, Acnp, Mina Yasuoka, Msn, Erika J. Yoo, Md

Phase 1

RATIONALE: Discharging patients directly from ICUs is an increasingly common practice, largely due to decreased availability of ward beds. The purpose of this study was to describe the population and evaluate the outcomes of patients discharged directly from the MICU.

METHODS: We conducted a retrospective chart review of direct discharges to home from June 2018 to June 2019 from two MICUs. Patients were separated into two groups based on wait time (<24 hours or ≥ 24 hours) between ward transfer order and actual discharge. The primary outcome was 30-day hospital readmission. Risk was adjusted using Mortality Probability Model (MPM-III); ICU workload at admission and discharge was estimated using the nine equivalents of nursing manpower use score (NEMS). Patient characteristics were compared using t-test and Fisher exact or X².

RESULTS: There was no difference in severity-of-illness or admission NEMS between the two groups. Patients who waited <24 hours for discharge were more likely to be admitted from home. Patients who waited ≥24 hours prior to discharge had significantly longer mean hospital LOS compared to those who waited <24 hours (4.63 days vs. 2.65 days, p<0.001). There was no significant difference in 30-day readmission between patients who were discharged after waiting <24 hours vs. waiting ≥24 hours (p=0.70).

CONCLUSION: Patients who returned directly home from the MICU …

What Is The Effect Of Iodine Contrast Agents On The Subharmonic Signal Generated From Ultrasound Contrast Agents?, Neal Kalantri, Cara Esposito, Jaydev Dave

Phase 1

Subharmonic-aided pressure estimation (SHAPE) is a technique utilizing subharmonic signals from microbubble-based ultrasound contrast agents (UCA’s) to noninvasively record pressures. Cardiac applications of SHAPE have been demonstrated in canines where low errors (0.19-2.5mmHg) were observed in canine ventricle pressures between the SHAPE technique and pressure catheter measurements. Validation of SHAPE involves simultaneous measurements by a pressure catheter (iodine contrast is used to guide catheter placement) and by SHAPE using UCAs. The goal of this experiment is to determine if mixing Visipaque (iodine contrast, GE Healthcare, Oslo, Norway) and UCAs effects the subharmonic signal.

The study was performed in an in …

Phenotype-Genotype Correlations In Patients With Epidermolysis Bullosa With Plec Mutations, Elizabeth Zhang, Masoomeh Faghankani, Hassan Vahidnezhad, Jouni Uitto

Phase 1

Epidermolysis bullosa (EB) is a heterogeneous group of genetic disorders characterized by blistering skin and mucous membranes. Mutations of the protein plectin, encoded by PLEC, cause autosomal recessive EB simplex with muscular dystrophy (EBS-MD) and EB simplex with pyloric atresia (EBS-PA). Until now, no clear genotype-phenotype correlation has been identified from the positions of mutations in the PLEC gene. How do ten distinct families with PLEC mutations manifesting as various EB disorders compare with regard to gene mutations? The hypothesis is that clinical manifestations of EB will be more extreme in patients with more severe gene mutations.
