Hospital Differences Drive Antibiotic Delays for Black Patients Compared With White Patients With Suspected Septic Shock.

OBJECTIVE: Evaluate racial disparities in sepsis processes of care. DESIGN: Observational cohort study. SETTING: Nine hospitals in the Southeastern United States between 2014 and 2016. PATIENTS: Two thousand two hundred twenty-one white and 707 black patients treated in the emergency department through "code sepsis" pathway for suspected septic shock. MEASUREMENTS AND MAIN RESULTS: Black patients were less likely to receive timely antibiotics than were white patients using multiple definitions (1 hr from code sepsis activation [odds ratio, 0.57; 95% CI, [0.44-0.74]; 85.6% vs. 91.2%; p < 0.0001]; 1 hr from triage [odds ratio, 0.83; 95% CI, [0.69-1.00]; 28.0% vs. 31.8%; p = 0.06]; 3 hr from triage [odds ratio, 0.71; 95% CI, [0.57-0.88]; 80.1% vs. 85.0%; p = 0.002]). Focusing on antibiotic administration within 1 hour of triage, these differences were enhanced after adjusting for patient-level factors (adjusted odds ratio, 0.80; 95% CI, [0.66-0.96]; p = 0.02), but attenuated after adjusting for hospital-level differences (adjusted odds ratio, 0.90; 95% CI, [0.81-1.01]; p = 0.07). Black and white patients did not differ on other sepsis quality indicators or adjusted mortality. CONCLUSIONS: Black patients appear to be less likely than white patients to receive timely antibiotic therapy for sepsis. These differences were largely explained by variation in care among hospitals, such that hospitals that disproportionately treat black patients were less likely to provide timely antibiotic therapy overall. There were no differences between races in other sepsis quality measures or adjusted mortality.

Clinical Factors and Outcomes of Dialysis-Dependent End-Stage Renal Disease Patients with Emergency Department Septic Shock.

BACKGROUND: Infection is the second leading cause of death in end-stage renal disease (ESRD) patients. Prior investigations of acute septic shock in this specific population are limited. OBJECTIVE: We aimed to evaluate the clinical presentation and factors associated with outcome among ESRD patients with acute septic shock. METHODS: We reviewed patients prospectively enrolled in an emergency department (ED) septic shock treatment pathway registry between January 2014 and May 2016. Clinical and treatment variables for ESRD patients were compared with non-ESRD patients. A second analysis focused on ESRD septic shock survivors and nonsurvivors. RESULTS: Among 4126 registry enrollees, 3564 (86.4%) met inclusion for the study. End-stage renal disease was present in 3.8% (n = 137) of ED septic shock patients. Hospital mortality was 20.4% and 17.1% for the ESRD and non-ESRD septic shock patient groups (p = 0.31). Septic shock patients with ESRD had a higher burden of chronic illness, but similar admission clinical profiles to non-ESRD patients. End-stage renal disease status was independently associated with lower fluid resuscitation dose, even when controlling for severity of illness. Age and admission lactate were independently associated with mortality in ESRD septic shock patients. CONCLUSION: ESRD patients comprise a small but important portion of patients with ED septic shock. Although presentation clinical profiles are similar to patients without ESRD, ESRD status is independently associated with lower fluid dose and compliance with the 30-mL/kg fluid goal. Hyperlactatemia is a marker of mortality in ESRD septic shock.

Urinary obstruction is an important complicating factor in patients with septic shock due to urinary infection.

OBJECTIVE: Urinary tract infection (UTI) is a common cause of severe sepsis, and anatomic urologic obstruction is a recognized factor for complicated disease. We aimed to identify the incidence of urinary obstruction complicating acute septic shock and determine the characteristics and outcomes of this group. METHODS: Patients prospectively enrolled in a sepsis treatment pathway registry between October 2013 and July 2014 were reviewed for the diagnosis of UTI. Standardized medical record review was performed to confirm sepsis due to UTI and determine clinical variables including the presence of anatomic urinary obstruction. Patients with septic shock due to UTI with obstruction were compared with those without obstruction. The primary outcomes were incidence of urinary obstruction and hospital mortality. RESULTS: Among 1084 registry enrollees, 209 (19.2%) met inclusion criteria for the study. Acute anatomic obstruction was identified in 22 (10.5%) patients. Hospital mortality in patients with obstruction was 27.3% compared with 11.2% in patients without obstruction (absolute difference of 16.1%; P = .03; 95% confidence interval [CI], 1.2%-30.9%). Hospital length of stay among survivors was 12.8 days compared with 8.3 days (absolute difference of 4.5 days; P = .04; 95% CI, 0.2-8.8 days). History of urinary stone disease was independently associated with obstruction (odds ratio, 5.6; 95% CI, 2.2-14.3). CONCLUSIONS: Approximately 1 in 10 patients presenting with septic shock due to a urinary source is complicated by anatomic urinary obstruction. These patients have significantly higher mortality compared with patients without obstruction. Early imaging of patients with septic shock due to suspected urinary source should be considered to identify obstruction requiring emergency intervention.

Cost Burden Impacts Cancer Patient Service Utilization Behavior in a US Commercial Plan.

Objectives: The burden of affording high-cost medical treatment (eg, cancer therapy) may impact whether some patients choose to access other needed health services within US commercial plans. However, deferring needed care for a mental or behavioral health (M/BH) condition could result in preventable hospital utilization. This research investigates how income level and total out-of-pocket costs (OOPC) interact to influence the service utilization behavior of insured adult cancer patients with a comorbid M/BH diagnosis. Methods: A cross-sectional, retrospective analysis was performed using medical service claims (July 2017-June 2018) and administrative data from eligible members of a large US commercial health benefits plan ( N =5,054). Nonparametric tests were used to examine variation in mean utilization by patient income level and OOPC decile. Negative binomial regression modeling was performed to analyze independent variable effects on count outcomes for outpatient behavioral visits and emergency department (ED) visits. Results: There was significant variation in patient service utilization by income level and total OOPC. Overall, as OOPC increased patients used less outpatient behavioral care ( p <.000). Compared to average and higher incomes, those with lower incomes (<$50,000/year) utilized significantly fewer outpatient visits ( p <.000) and significantly more ED visits ( p <.001) relative to increasing OOPC. Conclusions: The interaction of income level and OOPC (ie, cost burden) could inhibit patients' decision to access supportive behavioral care in the commercial plan. The cumulative cost burden from cancer treatment may promote underutilization of outpatient services and greater ED reliance, particularly among lower income plan members.

Impact of Multiprofessional Rounds on Critical Care Outcomes in the Surgical Trauma Intensive Care Unit.

Multiprofessional rounds (MPR) represent a mechanism for the coordination of care in critically ill patients. Herein, we examined the impact of MPR on ventilator days (Vent-day), ICU length of stay (LOS), hospital LOS (HLOS), and mortality. A team developed guidelines for MPR, which began in February 2016. Patients admitted between November 2015 and March 2017 with Acute Physiology and Chronic Health Evaluation (APACHE) IV and injury severity scores were included. Outcome data consisted of Vent-day, Vent-day observed/expected ratio (O/E), ICU LOS, ICU LOS O/E, HLOS, HLOS-O/E, and mortality. Linear regression models are constructed to assess statistical significance. A total of 3372 patients were included. Among surgical patients (n = 343 pre-MPR, n = 1675 post-MPR), MPR was associated with decreases in Vent-day O/E (0.74 pre, 0.59 post, P = 0.03), ICU LOS O/E (0.67 pre, 0.61 post, P = 0.01), and HLOS-O/E (1.47 pre, 1.22 post, P = 0.0005). No mortality difference was observed. For trauma patients (n = 221 pre, n = 1133 post), MPR resulted in a reduction in Vent-days (2.2 days pre, 1.6 days post, P = 0.05). However, no differences were observed for Vent-day O/E, ICU LOS O/E, HLOS-O/E, and mortality. Implementation of MPR was associated with improved outcomes for surgical trauma ICU patients. Sustainability of MPR remains a challenge and requires education and engagement.

Initial fluid resuscitation following adjusted body weight dosing is associated with improved mortality in obese patients with suspected septic shock.

OBJECTIVE: The optimal initial fluid resuscitation strategy for obese patients with septic shock is unknown. We evaluated fluid resuscitation strategies across BMI groups. MATERIALS AND METHODS: Retrospective analysis of 4157 patients in a multicenter activation pathway for treatment of septic shock between 2014 and 2016. RESULTS: 1293 (31.3%) patients were obese (BMI≥30). Overall, higher BMI was associated with lower mortality, however this survival advantage was eliminated in adjusted analyses. Patients with higher BMI received significantly less fluid per kilogram at 3h than did patients with lower BMI (p≤0.001). In obese patients, fluid given at 3h mimicked a dosing strategy based on actual body weight (ABW) in 780 (72.2%), adjusted body weight (AdjBW) in 95 (8.8%), and ideal body weight (IBW) in 205 (19.0%). After adjusting for condition- and treatment-related variables, dosing based on AdjBW was associated with improved mortality compared to ABW (OR 0.45; 95% CI [0.19, 1.07]) and IBW (OR 0.29; 95% CI [0.11,0.74]). CONCLUSIONS: Using AdjBW to calculate initial fluid resuscitation volume for obese patients with suspected shock may improve outcomes compared to other weight-based dosing strategies. The optimal fluid dosing strategy for obese patients should be a focus of future prospective research.
