Risk factors and outcomes of infected pancreatic necrosis: Retrospective cohort of 148 patients admitted to the ICU for acute pancreatitis.

ABSTRACT:

Objective

The primary objective of this article is to identify risk factors for infected pancreatic necrosis (IPN) in patients admitted to the intensive care unit (ICU) for severe acute pancreatitis. We also described outcomes of IPN.

Background

Acute pancreatitis is common and associated with multiple, potentially life-threatening complications. Over the last decade, minimally invasive procedures have been developed to treat IPN.

Methods

We retrospectively studied consecutive patients admitted for severe acute pancreatitis to the ICUs of the Nantes University Hospital in France, between 2012 and 2015. Logistic regression was used to evaluate potential associations linking IPN to baseline patient characteristics and outcomes.

Results

Of the 148 included patients, 26 (17.6%) died. IPN developed in 62 (43%) patients and consistently required radiological, endoscopic, and/or surgical intervention. By multivariate analysis, factors associated with IPN were number of organ failure (OF) (for???3: OR, 28.67 (6.23-131.96), p?ConclusionIPN occurred in nearly half our ICU patients with acute pancreatitis and consistently required interventional therapy. Number of OFs and portosplenomesenteric venous thrombosis were significantly associated with IPN. Early management of OF may reduce IPN incidence, and management of portosplenomesenteric venous thrombosis should be investigated.

Project description:BACKGROUND:Recent guidelines advise against prophylactic antibiotics in patients with necrotizing pancreatitis, advocating instead a step-up drainage and necrosectomy strategy with antibiotics as dictated by microbiological findings. However, prompt antibiotic therapy is recommended in patients with sepsis or septic shock, a possible presentation of infected pancreatic necrosis (IPN). Consequently, in many critically ill patients with IPN, pancreatic samples are collected only after broad-spectrum antibiotic therapy initiation. Whether this prior antibiotic exposure alters the microbiological findings is unknown. The main objective was to determine whether prior antibiotic exposure sterilized the samples collected during procedures for suspected IPN in patients admitted to the intensive care unit (ICU) for acute pancreatitis with suspected IPN. We retrospectively studied 56 consecutive ICU patients admitted with suspected IPN. We collected details on the microbiological samples and antimicrobials used. A definite diagnosis of IPN was given when bacteria were identified in pancreatic samples. RESULTS:In all, 137 pancreatic samples were collected, including 91 (66.4%) after antibiotic therapy initiation. IPN was confirmed in 48 (86%) patients. The proportion of positive samples was 74 (81.3%) in antibiotic-exposed patients and 32/46 (69.5%) in unexposed patients (p?=?0.58). Of the 74 positive samples from exposed patients, 62 (84%) had organisms susceptible to the antibiotics used. One-third of samples contained more than one organism. Among patients with IPN, 37.5% had positive blood cultures. Multidrug- or extensively drug-resistant bacteria were identified at some point in half the patients. Enterobacter cloacae complex was more frequent in the exposed group (p?=?0.02), as were Gram-negative anaerobic bacteria (p?=?0.03). CONCLUSION:Antibiotic exposure before sampling did not seem to affect culture positivity of pancreatic samples to confirm IPN, but may affect microbiological findings. Our results suggest that, in patients with sepsis and suspected IPN, antibiotics should be started immediately and pancreatic samples obtained as soon as possible thereafter. In other situations, antibiotics can be withheld until the microbiological results of pancreatic samples are available, to ensure accurate targeting of the spectrum to bacterial susceptibility patterns.

Project description:BACKGROUND:Tuberculous meningitis (TBM) is a devastating infection in tuberculosis endemic areas with limited access to intensive care. Functional outcomes of severe adult TBM patients admitted to the ICU in nonendemic areas are not known. METHODS:We conducted a retrospective multicenter cohort study (2004-2016) of consecutive TBM patients admitted to 12 ICUs in the Paris area, France. Clinical, biological, and brain magnetic resonance imaging (MRI) findings at admission associated with a poor functional outcome (i.e., a score of 3-6 on the modified Rankin scale (mRS) at 90 days) were identified by logistic regression. Factors associated with 1-year mortality were investigated by Cox proportional hazards modeling. RESULTS:We studied 90 patients, of whom 61 (68%) had a score on the Glasgow Coma Scale ? 10 at presentation and 63 (70%) required invasive mechanical ventilation. Brain MRI revealed infarction and hydrocephalus in 38/75 (51%) and 25/75 (33%) cases, respectively. A poor functional outcome was observed in 55 (61%) patients and was independently associated with older age (adjusted odds ratio (aOR) 1.03, 95% CI 1.0-1.07), cerebrospinal fluid protein level ? 2 g/L (aOR 5.31, 95% CI 1.67-16.85), and hydrocephalus on brain MRI (aOR 17.2, 95% CI 2.57-115.14). By contrast, adjunctive steroids were protective (aOR 0.13, 95% CI 0.03-0.56). The multivariable adjusted hazard ratio of adjunctive steroids for 1-year mortality (47%, 95% CI 37%-59%) was 0.23 (95% CI 0.11-0.44). Among survivors at 1 year, functional independence (mRS of 0-2) was observed in 27/37 (73%, 95% CI 59%-87%) cases. CONCLUSIONS:A poor functional outcome in adult TBM patients admitted to the ICU in a nonendemic area is observed in 60% of cases and is independently associated with elevated cerebrospinal fluid protein level and hydrocephalus. Our data also suggest a protective effect of adjunctive steroids, with reduced disability and mortality, irrespective of immune status and severity of disease at presentation. One-year follow-up revealed functional independence in most survivors.

Project description:ImportancePrognostication following ICU admission can often be determined based on known risk factors, including demographics and illness severity; however, little is known about outcomes of patients deemed to be "low-risk" at the time of hospital admission who subsequently are admitted to the ICU.ObjectivesThe objectives of this study were to determine the characteristics, outcomes, and costs for patients requiring ICU admission despite having lower predicted mortality when they were admitted to the hospital.Design setting and participantsIn this historical cohort study, we used a prospectively maintained ICU registry that included all ICU admissions to The Ottawa Hospital for patients 18 years or older from January 2011 to December 2016. We classified patients as low-risk using the Hospital-patient 1-year Mortality Risk at admission score, a hospital admission score validated to predict 1-year mortality.Main outcomes and measuresThe primary outcome was inhospital mortality. Secondary outcomes included adverse events, resource utilization, and costs.ResultsOf the 17,173 total ICU patients, 3,445 (20.1%) were classified as low-risk at hospital admission. Low-risk patients were younger (48.7 vs 67.5 yr; p < 0.001) and had a lower Multiple Organ Dysfunction Score (2.37 vs 4.14; p < 0.001). Mortality for low-risk patients was significantly lower than for non-low-risk patients (4.1% vs 25.4%; p < 0.001). For low-risk patients, multivariable logistic regression showed mortality was independently associated with older age (odds ratio, 1.02 per 1 yr; 95% CI, 1.00-1.03 per 1 yr), Multiple Organ Dysfunction Score (odds ratio, 1.42 per 1 point; 95% CI, 1.31-1.54 per 1 point), fluid management adverse events (odds ratio, 2.84; 95% CI, 1.29-6.25), hospital-acquired infections (odds ratio, 1.60; 95% CI, 1.02-2.51), and mechanical ventilation (odds ratio, 1.98; 95% CI, 1.20-3.26).Conclusions and relevanceDespite their robust premorbid status, low-risk patients admitted to the ICU had significant inhospital mortality. Fluid management adverse events, hospital-associated infections, multiple organ dysfunction, and mechanical ventilation are important prognostic factors for low-risk patients.
