Treatment costs of burn victims in a university hospital.

OBJECTIVES: To analyze the direct costs of treating critically ill patients in the intensive care unit of a center specializing in treating burns. METHODS: This is a prospective cohort study of 180 patients from May 2011 to May 2013. Clinical and demographic data were collected in addition to data for the calculation of severity scores. The costs related to daily clinical and surgical treatment were evaluated until hospital outcome. The costs were grouped into five blocks: Clinical support, Drugs and blood products, Medical procedures, Specific burn procedures and Hospital fees. The level of significance was set at 5%. RESULTS: There was a predominance of males, 131 (72.8%). The mean age of the patients was 42.0±15.3years and the mean burned body surface area was 27.9±17%. The median length of stay in intensive care beds was 15.0 (interquartile range IQR: 7.0-24.8) days and the median hospital stay was 23.0 (IQR: 14.0-34.0) days. The mean daily cost was US$ 1330.48 (standard error of the mean SE=38.36) and the mean total cost of hospitalization was US$ 39,594.90 (SE: 2813.11). The drugs and blood products block accounted for the largest fraction of the total costs (US$ 18,086.09; SE 1444.55). There was a difference in the daily costs of survivors and non survivors (US$ 1012.89; SE: 29.38 and US$ 1866.11, SE: 36.43, respectively, P<0.001). CONCLUSION: The direct costs of the treatment of burn patients at the study center were high. The drugs and blood products block presented the highest mean total and daily costs. Non surviving patients presented higher costs.

Epidemiology and outcome analysis of burn patients admitted to an Intensive Care Unit in a University Hospital.

OBJECTIVES: To describe the epidemiologic aspects of burn victims who were hospitalized in the Intensive Care Unit (ICU) at the Burn Center in the University Hospital of the State University of Londrina (UEL). METHODS: A longitudinal retrospective study was conducted, involving patients admitted to the Intensive Care Unit of the Burn Center from January 2010 to December 2012. Demographic and diagnostic data including the diagnosis of the extent and causes of the burns, complications resulting from the burns and the need for specific surgical interventions were collected, together with data for the calculation of the Acute Physiology and Chronic Health Evaluation (APACHE II), Sequential Organ Failure Assessment (SOFA), Therapeutic Intervention Scoring System (TISS-28) and Abbreviated Burn Severity Index (ABSI). Data were collected at admission and daily until discharge from the burn Intensive Care Unit. Risk factors for death and the prognostic performance of scores to predict mortality were analyzed. The level of significance was set at 5%. RESULTS: Two hundred ninety-three patients were analyzed in the study; 68.30% were men, with a median age of 38 years (interquartile range: 28-52). The mean total body surface area burned was 26.60±18.05%. Home incidents were the most frequent cause, occurring in 53.90% of the cases. Fire was the most common cause, found in 77.10% of patients. Liquid alcohol was the most common agent and was associated with 51.50% of the cases. The ABSI presented a median of 7, and the area under the ROC curve was 0.890. In multivariate analysis, age (p<0.001), female gender (p=0.02), total body surface area burned (p<0.001), mechanical ventilation (p<0.001) and acute renal failure (p<0.001) were all associated with mortality. ICU mortality was 32.80%, and hospital mortality was 34.10%. CONCLUSION: Burns most often occurred in young adult men in our study. The most common cause was a direct flame. Liquid alcohol was the most frequent accelerating agent. Patients were considered to be severely burned. Most of the samples had a high mean total body surface area burned. The ABSI score showed the best performance in discriminating non-survivors. Hospital mortality rate was high.

Impact of delayed admission to intensive care units on mortality of critically ill patients: a cohort study.

INTRODUCTION: When the number of patients who require intensive care is greater than the number of beds available, intensive care unit (ICU) entry flow is obstructed. This phenomenon has been associated with higher mortality rates in patients that are not admitted despite their need, and in patients that are admitted but are waiting for a bed. The purpose of this study is to evaluate if a delay in ICU admission affects mortality for critically ill patients. METHODS: A prospective cohort of adult patients admitted to the ICU of our institution between January and December 2005 were analyzed. Patients for whom a bed was available were immediately admitted; when no bed was available, patients waited for ICU admission. ICU admission was classified as either delayed or immediate. Confounding variables examined were: age, sex, originating hospital ward, ICU diagnosis, co-morbidity, Acute Physiology and Chronic Health Evaluation (APACHE) II score, therapeutic intervention, and Sequential Organ Failure Assessment (SOFA) score. All patients were followed until hospital discharge. RESULTS: A total of 401 patients were evaluated; 125 (31.2%) patients were immediately admitted and 276 (68.8%) patients had delayed admission. There was a significant increase in ICU mortality rates with a delay in ICU admission (P = 0.002). The fraction of mortality risk attributable to ICU delay was 30% (95% confidence interval (CI): 11.2% to 44.8%). Each hour of waiting was independently associated with a 1.5% increased risk of ICU death (hazard ratio (HR): 1.015; 95% CI 1.006 to 1.023; P = 0.001). CONCLUSIONS: There is a significant association between time to admission and survival rates. Early admission to the ICU is more likely to produce positive outcomes.

Serial evaluation of SOFA score in a Brazilian teaching hospital.

OBJECTIVES: To evaluate the application of the Sequential Organ Failure Assessment (SOFA) in describing the severity of organ dysfunctions and the associated mortality rates in critically ill patients at a teaching hospital. RESEARCH METHODOLOGY: Prospective longitudinal study performed in 1164 adult, critically ill patients who were admitted consecutively into intensive care units between January 2004 and December 2005. We analysed static evaluation of SOFA and dynamic changes in the SOFA scores. The discriminative power of SOFA was evaluated using ROC curves. RESULTS: There was an increase in the mortality rate when the SOFA scores increased (chi2(trend)=272.08, p<0.001, increase rate=0.13). The SOFA score on the third day in the ICU had the highest area under the curve for hospital mortality (AUC: 0.817+/-0.0133, CI 95%: 0.792-0.840). We analysed SOFA score changes with time and observed that patients with low scores (0-5) upon admission and who increased to the medium or high SOFA groups had a significantly higher mortality rate (51.7 and 100%, respectively, p<0.001). CONCLUSIONS: Applying SOFA to critically ill patients effectively described the severity of organ dysfunctions, and higher SOFA scores had a positive association with mortality.
