Management and outcome of 72 patients with severe sepsis.
<p>When not shown the patient denominator is 72. Where the denominator differs from this for a particular question, these are shown.</p

Diagnostic criteria used for organ dysfunction.
<p>Criteria were from the literature <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029858#pone.0029858-Bone1" target="_blank">[1]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029858#pone.0029858-Levy1" target="_blank">[2]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0029858#pone.0029858-Goldstein1" target="_blank">[27]</a> to fit the available data. Acute oliguria was determined from 24-hour urine because hourly urine output was infrequently monitored. Diagnostic criteria of arterial hypoxaemia (PaO<sub>2</sub>/FiO<sub>2</sub><300), ileus, and clinical signs of tissue hypoperfusion (decrease capillary refill or mottling) were not used as data were not recorded in the patient records. Laboratory testing for lactate level was not available in the hospital. The Glasgow Coma Score was not documented in patient records.</p
Association between patient characteristics and outcome for 270 patients with <i>S. aureus</i> infection.
<p>Data are number (%) unless otherwise stated.</p>*<p><sup>1</sup>p value for the comparison between all-cause deaths and survivors.</p>*<p><sup>2</sup>Denominator for occupation is number of patients over the age of 16 years which is given in each square.</p>*<p><sup>3</sup>Past medical history of any underlying chronic medical conditions reported by the patient/relative or recorded in the medical notes.</p>*<p><sup>4</sup>Immunosuppression from HIV (5 untreated, 3 on anti-retroviral therapy), chemotherapy (nβ=β3), untreated leukaemia (nβ=β1), radiotherapy (nβ=β1) or immunosuppressive medication including prednisolone more than 30 mg/day for more than 1 week (nβ=β17).</p>*<p><sup>5</sup>Renal disease included end stage renal failure on long-term dialysis (nβ=β3; 2 on haemodialysis, 1 on peritoneal dialysis) and chronic renal failure (not on dialysis) due to diabetes mellitus (nβ=β14), systemic lupus erythematosus (nβ=β1), multiple myeloma (nβ=β1), glomerulonephritis (nβ=β1) or an unknown aetiology (nβ=β5).</p>*<p><sup>6</sup>Cardiac disease comprised congenital heart disease (nβ=β4), valvular heart disease including rheumatic heart disease (nβ=β8), ischaemic heart disease (nβ=β8), or arrhythmias including heart block requiring pacemaker (nβ=β4).</p>*<p><sup>7</sup>Lung disease comprised previously treated tuberculosis (nβ=β9), previous empyema (nβ=β1), lung cancer (nβ=β2), long-term tracheostomy (nβ=β1), chronic obstructive pulmonary disease (nβ=β2) or asthma (nβ=β1).</p
Timely effective antibiotic therapy and procedures for infectious source control significantly improved outcome.
<p>Administration of an effective antibiotic on the same day as the positive culture was taken significantly reduced all-cause mortality (p<0.001), as did undergoing a procedure for infectious source control (p<0.001).</p
Significant risk factors for mortality from <i>S. aureus</i> infection from multiple logistic regression analysis.
*<p><sup>1</sup>95% confidence intervals.</p>*<p><sup>2</sup>p value from Likelihood ratio test.</p
Higher all-cause mortality associated with methicillin-resistant <i>S. aureus</i> (MRSA) but not with Panton-Valentine Leukocidin (PVL).
<p>Patients infected by MRSA had a greater all-cause mortality compared with patients infected by methicillin-susceptible <i>S. aureus</i> (MSSA) (p<0.001). Conversely, patients infected by PVL gene-positive <i>S. aureus</i> had a lower all-cause mortality compared with patients infected by PVL gene-negative <i>S. aureus</i> (p<0.001), an association that remained after adjustment for MRSA (pβ=β0.001).</p
The range of sites of infection in patients and outcome associated with each clinical presentation.
*<p><sup>1</sup>p value for the comparison between all-cause deaths and survivors.</p>*<p><sup>2</sup>Site of deep abscesses were muscle (nβ=β20), retroperitoneal space (nβ=β7), parotid gland (nβ=β7), liver (nβ=β3), lung (nβ=β2), epidural space (nβ=β2), eye (nβ=β2), oropharynx (nβ=β2) and spleen (nβ=β1).</p>*<p><sup>3</sup>Other skin and soft tissue infections includes: necrotising fasciitis (nβ=β9), bedsore(s) (nβ=β6), pustules and carbuncles (nβ=β5), infected wound from trauma (nβ=β3), infected wound from tophi (nβ=β2), gangrene (nβ=β2), cellulitis (without other skin or soft tissue lesion) (nβ=β2) and infection of exfoliated skin following a severe drug reaction (nβ=β2).</p>*<p><sup>4</sup>Orthopaedic material includes: internal fixation metalwork (nβ=β8) and a hip replacement (nβ=β1).</p>*<p><sup>5</sup>Intravenous devices were peripheral cannulas (nβ=β4), central catheters (nβ=β3) and an umbilical catheter (nβ=β1).</p>*<p><sup>6</sup>Endocarditis from transthoracic echocardiographic evidence of vegetations (nβ=β7); 1 case clinically but died prior to echocardiogram.</p>*<p><sup>7</sup>Other infections include: urinary tract infection (nβ=β3), tenosynovitis (nβ=β2), Lemierre's syndrome (nβ=β1) and corneal ulcer (nβ=β1).</p>*<p><sup>8</sup>Post-operative infections include: mediastinitis (nβ=β4; 3 following mitral valve replacement and 1 after coronary artery bypass graft), meningitis from infected bone flap surgical wound (nβ=β1) and abdominal wound (nβ=β1).</p
