Physician and Trainee Perceptions of Telecritical Care Practice and Education: Results of a Programmatic Survey.

Background: Telecritical care (TCC) as a telehealth modality seeks to remedy contemporary shortfalls in staffing and experience at the bedside. Physician and physician trainee perceptions of TCC practice and education can help inform programmatic and curricular decisions. The perceptions of TCC and a formalized structured TCC rotation from faculty and trainees are unknown. Objective: To evaluate perceptions of TCC practice and education among participating physicians and trainees. Methods: Survey of physicians and trainees participating in the Emory Critical Care Center's TCC unit from 2017 to 2021 was conducted, after implementation of a structured TCC educational curriculum. Items were developed with a 5-point Likert scale. Results: The overall response rate was 71% (43 of 61). Most respondents felt their knowledge was used appropriately and that their recommendations were well received at the bedside. The majority perceived that the TCC program improved continuity, quality, and safety of patient care. More than half of respondents would practice TCC in the future, and most would advocate for it. Most fellows were comfortable providing patient care remotely after their rotation. The majority of respondents felt TCC did not add to their level of burnout. Conclusions: This programmatic evaluation identified perceived improvements in patient care. Implementation of a TCC rotation does not seem to negatively impact the educational experience of trainees.

Modes of mechanical ventilation vary between hospitals and intensive care units within a university healthcare system: a retrospective observational study.

OBJECTIVE: As evidence-based guidance to aid clinicians with mechanical ventilation mode selection is scant, we sought to characterize the epidemiology thereof within a university healthcare system and hypothesized that nonconforming approaches could be readily identified. We conducted an exploratory retrospective observational database study of routinely recorded mechanical ventilation parameters between January 1, 2010 and December 31, 2016 from 12 intensive care units. Mode epoch count proportions were examined using Chi squared and Fisher exact tests as appropriate on an inter-unit basis with outlier detection for two test cases via post hoc pairwise analyses of a binomial regression model. RESULTS: Final analysis included 559,734 mode epoch values. Significant heterogeneity was demonstrated between individual units (P < 0.05 for all comparisons). One unit demonstrated heightened utilization of high-frequency oscillatory ventilation, and three units demonstrated frequent synchronized intermittent mandatory ventilation utilization. Assist control ventilation was the most commonly recorded mode (51%), followed by adaptive support ventilation (23.1%). Volume-controlled modes were about twice as common as pressure-controlled modes (64.4% versus 35.6%). Our methodology provides a means by which to characterize the epidemiology of mechanical ventilation approaches and identify nonconforming practices. The observed variability warrants further clinical study about contributors and the impact on relevant outcomes.

The impact of telemedicine in cardiac critical care.

Telemedicine was recognized in the 1970s as a legitimate entity for applying the use of modern information and communications technologies to the delivery of health services. Telecardiology is one of the fastest growing fields in telemedicine. The advancement of technologies and Web-based applications has allowed better transmission of health care delivery. This article discusses current advancements, the scope of telemedicine in cardiology, and its application to the critically ill. The impact of telecardiology consultation continues to evolve and includes many promising applications with potential positive implications for admission rates, morbidity, and mortality.

A multicenter population-based effectiveness study of teleintensive care unit-directed ventilator rounds demonstrating improved adherence to a protective lung strategy, decreased ventilator duration, and decreased intensive care unit mortality.

PURPOSE OF THE STUDY: The purpose of the study is to determine if teleintensive care unit (ICU)-directed daily ventilator rounds improved adherence to lung protective ventilation (LPV), reduced ventilator duration ratio (VDR), and ICU mortality ratios. METHOD USED: A retrospective observational longitudinal quarterly analysis of adherence to low tidal volume LPV (<7.5 mL/kg predicted body weight; Pao2/fraction of inspired oxygen<300), ventilator duration, and ICU mortality ratios (Acute Physiology and Chronic Health Evaluation IV-adjusted). The teleICU practice used Philips (Andover, MA) VISICU eCareManagerTM (Andover, MA) platform, providing ICU care and process improvement. RESULTS: Before ventilator rounds implementation, there was wide variation in hospital adherence to low tidal volume (29.5±18.2; range 10%-69%). Longitudinal improvement was seen across hospitals in the 3 Qs after implementation, reaching statistical significance by Q3 postimplementation (44.9±15.7; P<.002 by 2-tailed Fisher exact test), maintained at 2 subsequent Qs (48% and 52%; P<.001). Ventilator duration ratio also showed preimplementation variability (1.08±.34; range 0.71-1.90). After implementation, absolute and significant mean VDR reduction was observed (0.92±.28; -15.8%, P<.05). Intensive care unit mortality ratio demonstrated longitudinal improvement, reaching significance after the Q3 postimplementation (0.94 vs 0.67; P<.04), and this was sustained in the most recent Q analyzed (0.65; P<.03). CONCLUSIONS: Implementation of teleICU-directed ventilator rounds was associated with improved and durable adherence to LPV and significant reductions in both VDR and ICU mortality.

Isolated tricuspid valve surgery: predictors of adverse outcome and survival.

BACKGROUND: Isolated tricuspid valve surgery is a rare operation, for which outcomes are not well defined. We describe a single-centre experience with isolated tricuspid surgery, and an analysis of risk factors for adverse outcome and predictors of survival. METHODS: Retrospective analysis of 56 consecutive adult patients undergoing isolated tricuspid valve surgery between November 1998 and November 2010 was performed. RESULTS: Eight patients died in hospital (early mortality 14.2%). In comparison with tricuspid repair patients, tricuspid replacement patients required more intraoperative red cell blood transfusion (RBC>1 unit: p=0.033), platelet transfusion (p=0.051), and more postoperative ventilator support (p=0.023). Predictors of early (in hospital) mortality include advanced age (p=0.019) higher euroSCORE (p<0.001), transfusion of intraoperative red blood cells (p=0.005), and cryoprecipitate (p=0.014). Twenty-five patients (44.6%) reached the end-point of death. There was no statistical difference in early and late survival rates between repair and replacement groups. CONCLUSIONS: Patients with isolated tricuspid valve surgery continue to be a high-risk group in cardiac surgery with unacceptable operative mortality and limited survival. There were no statistical differences in early and late outcomes between the isolated tricuspid valve repair versus replacement surgery. Timely referral to surgery before the onset of class 3 heart failure, malnutrition, renal dysfunction and age>60 years is recommended.

A model to create an efficient and equitable admission policy for patients arriving to the cardiothoracic ICU.

OBJECTIVE: To develop queuing and simulation-based models to understand the relationship between ICU bed availability and operating room schedule to maximize the use of critical care resources and minimize case cancellation while providing equity to patients and surgeons. DESIGN: Retrospective analysis of 6-month unit admission data from a cohort of cardiothoracic surgical patients, to create queuing and simulation-based models of ICU bed flow. Three different admission policies (current admission policy, shortest-processing-time policy, and a dynamic policy) were then analyzed using simulation models, representing 10 yr worth of potential admissions. Important output data consisted of the "average waiting time," a proxy for unit efficiency, and the "maximum waiting time," a surrogate for patient equity. SETTING: A cardiothoracic surgical ICU in a tertiary center in New York, NY. PATIENTS: Six hundred thirty consecutive cardiothoracic surgical patients admitted to the cardiothoracic surgical ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Although the shortest-processing-time admission policy performs best in terms of unit efficiency (0.4612 days), it did so at expense of patient equity prolonging surgical waiting time by as much as 21 days. The current policy gives the greatest equity but causes inefficiency in unit bed-flow (0.5033 days). The dynamic policy performs at a level (0.4997 days) 8.3% below that of the shortest-processing-time in average waiting time; however, it balances this with greater patient equity (maximum waiting time could be shortened by 4 days compared to the current policy). CONCLUSIONS: Queuing theory and computer simulation can be used to model case flow through a cardiothoracic operating room and ICU. A dynamic admission policy that looks at current waiting time and expected ICU length of stay allows for increased equity between patients with only minimum losses of efficiency. This dynamic admission policy would seem to be a superior in maximizing case-flow. These results may be generalized to other surgical ICUs.

Noncardiac entrapment of a pulmonary artery catheter during heart transplantation: inadvertent cannulation and perforation of the internal thoracic vein.

Placement of a central venous catheter into an internal thoracic vein occurs in approximately 2% of all catheterizations. A case in which a pulmonary artery catheter was trapped within the internal thoracic vein during orthotopic heart transplantation is presented.

The economics of glycemic control in the ICU in the United States.

PURPOSE OF REVIEW: Currently the USA has an aging population, with increasing deficits and a healthcare system that most would agree is in need of repair. Finding ways to curtail costs is urgently needed. Attention to glycemic control and metabolic care offers a cost-effective method of treatment to reduce complications. RECENT FINDINGS: Healthcare-related expenses occupy an expanding portion of gross domestic product in the US and are a driver of the deficit. Despite all of this spending, the US receives average marks on outcomes and is not obtaining value in its healthcare. Any movements toward healthcare reform must focus on improving outcomes per healthcare dollar spent, and increasing value. The Affordable Care Act will place greater emphasis on preventing complications and reducing hospital-acquired infections. The original Leuven trial demonstrated that proper implementation of glycemic control can reduce morbidity and mortality. More recent studies have shown that there is a cost-benefit to glycemic control as well, through reduction of hospital stay and prevention of complications. On the basis of these changes, physicians who practice metabolic care and provide glycemic control are well positioned to add value in this era of healthcare reform. SUMMARY: Glycemic control is inherently valuable in the care of ICU patients as it decreases infectious complications, reduces lengths of stay, and has a positive effect on morbidity and mortality. Further studies should be completed to delineate the exact amount of cost-savings that can be obtained by proper implementation of glycemic control in the ICU.

Adjuvant therapy with methylene blue in the treatment of right ventricular failure after pulmonary embolectomy.

Severe pulmonary embolism often leads to right ventricular failure after surgical embolectomy secondary to ischaemia reperfusion injury and acute lung injury (ALI). Acute right ventricular dysfunction is traditionally treated with inotropes and vasopressors to maintain cardiac output and coronary perfusion as well as selective pulmonary vasodilators to provide right ventricular afterload reduction. We report the first case of utilisation of methylene (MB) in a patient with acute right ventricular failure and vasoplegic shock after surgical pulmonary embolectomy.

The efficacy of post-cardiopulmonary bypass dosing of vancomycin in cardiac surgery.

Objective. Vancomycin is administered widely to patients undergoing cardiac surgery as prophylaxis against resistant Gram-positive sternal wound and venous donor site infections. The purpose of this study was to determine the efficacy of a standardized prebypass and postbypass dosing regimen of vancomycin by assessing plasma concentrations in the immediate postoperative period and postoperative surgical site infections (SSIs). Design. Retrospective cohort study. Setting . Cardiothoracic surgical intensive care unit in a tertiary care academic medical center. Methods. A total of 34 consecutive adult patients who had undergone cardiac surgery with cardiopulmonary bypass (CPB) were analyzed retrospectively. Each patient received 1000 mg of vancomycin administered over 1 hour around the time of induction of anesthesia and 500 mg after discontinuation of CPB. Trough vancomycin levels were sampled in the intensive care unit 12 hours after the last dose given in the operating room. Along with patient characteristics, postoperative readmission rates and SSIs were recorded for 1 year after surgery. Results. The nadir serum vancomycin level before the next dose was 9.3 ± 4.5 µg/mL (mean ± standard deviation). One superficial SSI was noted. Readmission rate for SSIs was 2.94%. Conclusion . Vancomycin concentrations in the serum were greater than the minimum inhibitory concentration for most staphylococci ranging from 4 to 19.3 µg/mL producing acceptable therapeutic serum concentrations and low rate of infectious complications. Thus postbypass dosing is acceptable in vancomycin cardiac surgical prophylaxis.

Predictive model for postoperative delirium in cardiac surgical patients.

Delirium is a common complication following cardiac surgery, and the predictors of delirium remain unclear. The authors performed a prospective observational analysis to develop a predictive model for postoperative delirium using demographic and procedural parameters. A total of 112 adult postoperative cardiac surgical patients were evaluated twice daily for delirium using the Richmond Agitation-Sedation Scale (RASS) and Confusion Assessment Model for the ICU (CAM-ICU). The incidence of delirium was 34% (n = 38). Increased age (odds ratio [OR] = 2.5; 95% confidence interval [CI] = 1.6-3.9; P < .0001, per 10 years) and increased duration of surgery (OR = 1.3; 95% CI = 1.1-1.5; P = .0002, per 30 minutes) were independently associated with postoperative delirium. Gender, BMI, diabetes mellitus, preoperative ejection fraction, surgery type, length of cardiopulmonary bypass, intraoperative blood component administration, Acute Physiology and Chronic Health Evaluation II score, Sequential Organ Failure Assessment score, and Charlson Comorbidity Index, were not independently associated with postoperative delirium.
