Early goal-directed therapy in severe sepsis and septic shock: insights and comparisons to ProCESS, ProMISe, and ARISE.

Prior to 2001 there was no standard for early management of severe sepsis and septic shock in the emergency department. In the presence of standard or usual care, the prevailing mortality was over 40-50 %. In response, a systems-based approach, similar to that in acute myocardial infarction, stroke and trauma, called early goal-directed therapy was compared to standard care and this clinical trial resulted in a significant mortality reduction. Since the publication of that trial, similar outcome benefits have been reported in over 70 observational and randomized controlled studies comprising over 70,000 patients. As a result, early goal-directed therapy was largely incorporated into the first 6 hours of sepsis management (resuscitation bundle) adopted by the Surviving Sepsis Campaign and disseminated internationally as the standard of care for early sepsis management. Recently a trio of trials (ProCESS, ARISE, and ProMISe), while reporting an all-time low sepsis mortality, question the continued need for all of the elements of early goal-directed therapy or the need for protocolized care for patients with severe and septic shock. A review of the early hemodynamic pathogenesis, historical development, and definition of early goal-directed therapy, comparing trial conduction methodology and the changing landscape of sepsis mortality, are essential for an appropriate interpretation of these trials and their conclusions.

Ultrasound-assisted catheter-directed thrombolysis versus anticoagulation alone for management of submassive pulmonary embolism.

BACKGROUND: Patients with submassive pulmonary embolism (PE) are vulnerable to sudden deterioration, recurrent PE, and progression to pulmonary hypertension and chronic right ventricular (RV) dysfunction. Previous studies have suggested a clinical benefit of using ultrasound-assisted catheter-directed thrombolysis (USCDT) to invasively manage patients with submassive PE. However, there is sparse data comparing the clinical outcomes of these patients when treated with USCDT versus anticoagulation (AC) alone. We sought to compare the outcomes of USCDT versus AC alone in the management of submassive PE. METHODS: 192 consecutive patients who underwent USCDT for submassive PE between January 2013 and February 2019 were identified. ICD9/ICD10 codes were used to detect 2554 patients diagnosed with PE who did not undergo thrombolysis. Propensity matching identified 192 patients with acute PE treated with AC alone. Clinical outcomes were compared between the two groups. Baseline demographics, laboratory values, and pulmonary embolism severity index scores were similar between the two cohorts. RESULTS: There was a significant reduction in mean systolic pulmonary artery pressure (sPAP) in the USCDT group compared to the AC group (∆11 vs ∆3.9 mmHg, p < 0.001). There was significant improvement in proportion of RV dysfunction in all patients, but the difference was larger in the USCDT group (∆43.3% vs ∆17.3%, p < 0.001). Patients who underwent USCDT had lower 30-day (4.3% vs 10.5%, p = 0.03), 90-day (5.5% vs 12.4%, p = 0.03), and 1-year mortality (6.2% vs 14.2%, p = 0.03). CONCLUSIONS: In patients with acute submassive PE, USCDT was associated with improved 30-day, 90-day, and 1 year mortality as compared to AC alone. USCDT also improved RV function and reduced sPAP to a greater degree than AC alone. Further studies are needed to verify these results in both short- and long-term outcomes.

Subclinical CMV viremia is associated with increased nosocomial infections and prolonged hospitalization in patients with systemic autoimmune diseases.

OBJECTIVE: Subclinical cytomegalovirus (CMV) viremia has been associated with other infections, prolonged hospitalization, and mortality in select immunosuppressed populations. We examined the incidence and outcomes of subclinical CMV viremia in hospitalized patients with systemic autoimmune diseases (AD) [systemic lupus erythematosus (SLE) or anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV)] using a highly sensitive CMV assay. METHODS: Prospectively collected samples were obtained from AD hospitalized patients at study entry with a second sample collected 1 week later or at hospital discharge. Controls included age- and gender- matched inpatients without AD and outpatients with AD. All samples were tested in batch using the Abbott RealTime CMV for investigational use assay (RT assay), with a LLOD (LLOQ) at 21 IU/mL (32 IU/mL). RESULTS: Twenty-three inpatients (10 SLE, 8 AAV, 5 controls), and 31 outpatient controls were recruited. Subclinical CMV viremia was found in 61% (11/18) of inpatient AD subjects, 3% (1/31) of outpatient AD subjects, and in none of the five inpatient controls (p < 0.001). CMV viremia was associated with increased median length of ICU stay (13 vs. 4 days, p = 0.033), hospital stay (17 vs. 9 days, p = 0.014) and increased nosocomial infections (7 vs. 1, p = 0.007). CMV viremia was not associated with overall severity of illness nor with disease-specific activity or damage. CONCLUSION: Over one-half of hospitalized AD patients in our cohort had detectable CMV viremia, which was associated with increased length of hospital stay and nosocomial infections. These data suggest that further study of the immunomodulatory effects of subclinical CMV viremia in AD is warranted.

Serious illness conversations in pulmonary hypertension.

Pulmonary arterial hypertension has evolved from a fatal disease with few treatment options to a chronic condition with improved survival. This improvement is possible through development of effective therapies as well as the expansion of risk stratification scores to assist clinical decision making. Despite improved disease control, quality of life, and overall prognosis, many challenges remain. The treatment itself is burdensome, with significant impact on quality of life. Many patients with pulmonary arterial hypertension still present with advanced, often end-stage disease. Increased use of mechanical circulatory support and catheter-based interventions have expanded use of extracorporeal life support and right ventricle assist devices. For these reasons as well as the long-term relationships pulmonary hypertension physicians have with patients and their families, navigating the course of the illness in a considered, proactive way is essential. Understanding individual goals and revisiting them as they change over time requires comfort with the conversation itself. There are many barriers and challenges to having effective, compassionate conversations in the clinical setting with time constraints being the most often cited. Compressed visits are necessarily focused on the clinical aspects, therapy and medication adherence and tolerance. Clinicians are sometimes wary of diminishing hope in the face of ongoing treatment. Having sufficient experience and comfort with these discussions can be empowering. In this paper, we discuss the challenges involved and propose a framework to assist in incorporating these discussions into clinical care.

Designing a Yoga Intervention Program to Improve Well-Being for Physician Trainees: Challenges and Lessons Learned.

Well-being activities may help to counteract physician burnout. Yoga is known to enhance well-being, but there are few studies of yoga as an intervention for physicians in training. This prospective methodology-development study aimed to explore how to establish a yoga-based well-being intervention for physician trainees in a large urban training hospital. We aimed to identify factors that contribute to trainee participation and explore an instrument to measure changes in self-reported well-being after yoga. Cohorts included a required-attendance group, a voluntary-attendance group, and an unassigned walk-in yoga group. Weekly 1-hour yoga sessions were led by a qualified yoga instructor for 4 weeks. The seven-question Resident Physician Well-Being Index (RPWBI) was used to measure resident well-being before yoga, after 4 weeks of yoga, and 6 months post-yoga. Trainees attending each session ranged from 17 for required yoga to 0-2 for voluntary yoga, 2-9 for lunchtime walk-in yoga, and 1-7 for evening walk-in yoga. In the required-yoga group (n = 17), overall RPWBI mean scores did not change significantly across the three query times, and participation in the survey declined over time. The mean baseline RPWBI score for the required group before yoga was in the non-distressed range and answers to the seven individual questions varied. Requiring a yoga activity for medical trainees may be a good strategy for promoting participation in yoga. The RPWBI may have limited utility for measuring changes in overall group well-being after a yoga intervention.

Improving transitions of care for critically ill adult patients on pulmonary arterial hypertension medications.

PURPOSE: The purpose of this report is to describe the activities of critical care and ambulatory care pharmacists in a multidisciplinary transitions-of-care (TOC) service for critically ill patients with pulmonary arterial hypertension (PAH) receiving PAH medications. SUMMARY: Initiation of medications for treatment of PAH involves complex medication access steps. In the ambulatory care setting, multidisciplinary teams often have a process for completing these steps to ensure access to PAH medications. Patients with PAH are frequently admitted to an intensive care unit (ICU), and their home PAH medications are continued and/or new medications are initiated in the ICU setting. Inpatient multidisciplinary teams are often unfamiliar with the medication access steps unique to PAH medications. The coordination and completion of medication access steps in the inpatient setting is critical to ensure access to medications at discharge and prevent delays in care. A PAH-specific TOC bundle for patients prescribed a PAH medication who are admitted to the ICU was developed by a multidisciplinary team at an academic teaching hospital. The service involves a critical care pharmacist completing a PAH medication history, assessing for PAH medication access barriers, and referring patients to an ambulatory care pharmacist for postdischarge telephone follow-up. In collaboration with the PAH multidisciplinary team, a standardized workflow to be initiated by the critical care pharmacist was developed to streamline completion of PAH medication access steps. Within 3 days of hospital discharge, the ambulatory care pharmacist calls referred patients to ensure access to PAH medications, provide disease state and medication education, and request that the patient schedule a follow-up office visit to take place within 14 days of discharge. CONCLUSION: Collaboration by a PAH multidisciplinary team, critical care pharmacist, and ambulatory care pharmacist can improve TOC related to PAH medication access for patients with PAH. The PAH TOC bundle serves as a model that may be transferable to other health centers.

Transitioning Parenteral or Inhaled Treprostinil to Oral Treprostinil Diolamine: Case Series and Review of the Literature.

Treprostinil diolamine is the first oral dosage preparation of a prostacyclin analogue for use in treatment naive pulmonary arterial hypertension (PAH). This case series and review of the available literature describes the experience of patients with PAH receiving treprostinil by intravenous (IV), subcutaneous (SQ), or inhalation route who were transitioned to treprostinil diolamine. At our institution, 3 patients were transitioned to treprostinil diolamine who received treprostinil administered by each of the alternative routes: IV, SQ, and inhalation. All patients tolerated the transition without significant worsening of disease end points. In the literature, 5 additional reports representing 48 patients were transitioned to treprostinil diolamine from an alternate route of administration. A majority (92%) of patients were hospitalized during the cross-titration phase and tolerated the transition without changes in disease markers or significant adverse effect. Six (13%) patients required reinitiation of parenteral therapy due to clinical decline. The most common dosing frequency utilized for treprostinil diolamine was 3 times per day. In patients with stable PAH receiving parenteral or inhaled treprostinil, a transition to treprostinil diolamine was a safe approach in a highly select population meeting clinical end points. Additional studies are required to further describe this clinical strategy before accepted in clinical practice.

Low Rate of Adverse Events Associated With Inpatient Parenteral Prostacyclins.

Parenteral prostacyclin is the most-effective therapy for patients with pulmonary arterial hypertension. Administration is complex, and administration errors are potentially life threatening. Hospital policies to minimize the risk to patients are necessary, but their effectiveness has not been well studied. We quantified the adverse event incident rate per at-risk patient day in a tertiary care hospital with an established parenteral prostacyclin policy. Patients on parenteral prostacyclin including new initiations from January 2003 to January 2013 were identified, encompassing 386 discrete admissions. Reports of adverse events were obtained from the inpatient risk feedback-reporting process and detailed chart review. Policy-divergent events were analyzed both categorically and by the degree of severity. Overall, 153 total policy-divergent events were identified. Data analysis indicated an incident rate of 45.9 per 1,000 patient days. In total, 21 of 153 potential errors reached the patient, translating to an incident rate of 6.3 per 1,000 patient days. Incident rate for "serious symptomatic" or "catastrophic" policy-divergent events was 3.3 per 1,000 patient days. Even with specific prostacyclin training and administration policy, there remains a small risk of adverse events in hospitalized pulmonary hypertension patients receiving parenteral prostacyclin.

CURB-65 and SMRT-CO in the prediction of early transfers to the intensive care unit among patients with community-acquired pneumonia initially admitted to a general ward.

BACKGROUND: No study has assessed the ability of pneumonia severity scores to identify the risk for early intensive care unit (ICU) transfer in patients with community-acquired pneumonia (CAP) admitted to general wards (GW). We aimed to compare the ability of CURB-65 (confusion, urea level, respiratory rate, blood pressure, and age ≥65 years) and SMRT-CO (systolic blood pressure, multilobar chest radiography involvement, respiratory rate, tachycardia, confusion, and oxygenation) scores to predict early ICU transfers in these patients. DESIGN: Retrospective, case-control study. Cases were defined as patients admitted to GW with CAP that required ICU transfer within 48 hours. Controls were defined as patients admitted to GW with CAP that did not require ICU transfer. CURB-65 and SMRT-CO scores were calculated on presentation to emergency department (ED), and upon admission to GW. Composite scores were calculated combining data from ED and GW. Sensitivities, specificities, likelihood ratios, and areas-under-the-curve (AUC) were calculated for each score. RESULTS: From 2003 to 2009, 115 cases and 345 controls were identified. Both groups had similar baseline characteristics. Composite scores combining data from ED and GW had better sensitivity and AUC than scores calculated only with ED or GW data (P < 0.001). A composite SMRT-CO score ≥2 had 76.5% (95% CI, 67.7 to 83.9) sensitivity, 67.5% (95% CI, 62.3 to 72.4) specificity, and 0.81 (95% CI, 0.77 to 0.85) AUC. A composite CURB-65 score ≥3 had 36.5% (95% CI, 27.7 to 46.0) sensitivity, 86.3% (95% CI, 82.3 to 89.8) specificity, and 0.66 (95% CI, 0.60 to 0.72) AUC to predict early ICU transfers. Composite SMRT-CO had higher sensitivity and AUC (P < 0.001) than composite CURB-65. CONCLUSIONS: Composite SMRT-CO had a better combination of sensitivity and specificity than CURB-65 for predicting early ICU transfers. Prospective studies to confirm our findings are needed.
