A Single-Center Prospective Cohort Study on Postsplenectomy Sepsis and its Prevention.

ABSTRACT: Background:This study evaluated the impact of a dedicated outpatient service on vaccination uptake after splenectomy and on the incidence of postsplenectomy sepsis. Methods:From 2009 to 2016 at the University Hospital Freiburg (Germany), asplenic patients were referred to a dedicated outpatient service, provided with comprehensive preventive care including vaccinations, and enrolled in a prospective cohort study. The impact of the service on vaccination uptake and the occurrence of severe sepsis/septic shock was compared between patients who had splenectomy (or were asplenic) within 3 months of study entry ("early study entry") and those who had splenectomy (or were asplenic) >3 months before study entry ("delayed study entry"). Results:A total of 459 asplenic patients were enrolled, and 426 patients were followed prospectively over a median period of 2.9 years. Pneumococcal vaccine uptake within 3 months of splenectomy or first diagnosis of asplenia was 27% vs 71% among delayed study entry and early study entry patients, respectively (P < .001). Forty-four episodes of severe sepsis or septic shock occurred in study patients: 22 after study entry and 22 before study entry. Streptococcus pneumoniae was more frequent among sepsis episodes that occurred before study entry (8/22) than after study entry (1/22 episodes). For episodes occurring after study entry, only a higher Charlson comorbidity index score was significantly associated with severe sepsis/septic shock postsplenectomy. Conclusions:With dedicated outpatient care, high uptake of pneumococcal vaccination postsplenectomy was achieved. Sepsis episodes were largely of nonpneumococcal etiology in patients who had received dedicated postsplenectomy care.

Project description:ObjectivesIncrease of nucleated RBCs in peripheral blood has been shown to be predictive of mortality in ICU patients. The aim of this study was to explore the prognostic value of nucleated RBCs in the first blood sample taken at admission to the emergency department from patients with suspected sepsis.DesignSingle-center prospective cohort study.SettingEmergency department.PatientsOne-thousand two-hundred thirty-one consecutive adult patients with suspected sepsis were included in a prospective quality register-based cohort study. Inclusion criteria were as follows: patients received in rapid response team with blood cultures taken and immediate antibiotics given in the emergency department.InterventionNot applicable.Measurement and main resultsNucleated RBCs, Sequential Organ Failure Assessment score, Quick Sequential Organ Failure Assessment, Charlson Comorbidity Index, and commonly used laboratory tests measured in the emergency department were compared with 30-day mortality. Nvaucleated RBC counts were divided into five groups, called "Nucleated RBC score," according to nucleated RBC count levels and analyzed with logistic regression together with the Sequential Organ Failure Assessment score and Charlson Comorbidity Index. Of the 262 patients with nucleated RBCs equal to or higher than the detection limit (0.01 × 109/L), 26% died within 30 days, compared with 12% of the 969 patients with nucleated RBCs below the detection limit (p < 0.0001). Mortality was significantly higher for each increase in Nucleated RBC score, except from score 2 to 3, and was 62% in the highest group. In multivariate logistic regression, odds ratios for 30-day mortality were as follows: Nucleated RBC score: 1.33 (95% CI, 1.13-1.56), Sequential Organ Failure Assessment score: 1.32 (1.29-1.56), and Charlson Comorbidity Index: 1.17 (1.09-1.25).ConclusionsMost patients with suspected sepsis in emergency department had undetectable nucleated RBCs at admission to the emergency department. However, increased nucleated RBCs significantly predicted 30-day mortality. Nucleated RBCs may provide additional prognostic information to Sequential Organ Failure Assessment score and other laboratory tests.

Project description:BackgroundThe burden of sepsis is highest in low- and middle-income countries, though the management of sepsis in these settings is poorly characterized. Therefore, the objective of this study was to assess the early management of sepsis in Thailand.MethodsPre-planned analysis of the Ubon-sepsis study, a single-center prospective cohort study of Thai adults admitted to the general medical wards and medical intensive care units (ICUs) of a regional referral hospital with community-acquired sepsis.ResultsBetween March 2013 and January 2017, 3,716 patients with sepsis were enrolled. The median age was 59 years (IQR 44-72, range 18-101), 58% were male, and 88% were transferred from other hospitals. Eighty-six percent of patients (N = 3,206) were evaluated in the Emergency Department (ED), where median length of stay was less than 1 hour. Within the first day of admission, most patients (83%, N = 3,089) were admitted to the general medical wards, while 17% were admitted to the ICUs. Patients admitted to the ICUs had similar age, gender, and comorbidities, but had more organ dysfunction and were more likely to receive measured sepsis management interventions. Overall, 84% (N = 3,136) had blood cultures ordered and 89% (N = 3,308) received antibiotics within the first day of hospital admission. Among the 3,089 patients admitted to the general medical wards, 38% (N = 1,165) received an adrenergic agent, and 21% (N = 650) received invasive mechanical ventilation. Overall mortality at 28 days was 21% (765/3,716), and 28-day mortality in patients admitted to the ICUs was higher than that in patients admitted to the general medical wards within the first day (42% [263/627] vs. 16% [502/3,089], p < 0.001).ConclusionsSepsis in a regional referral hospital in rural Thailand, where some critical care resources are limited, is commonly managed on general medical wards despite high rates of respiratory failure and shock. Enhancing sepsis care in the ED and general wards, as well as improving access to ICUs, may be beneficial in reducing mortality.Trial registrationThe Ubon-sepsis study was registered on clinicaltrials.gov (NCT02217592).
