Identifying possible deaths associated with nosocomial infection in a hospital by data mining

Factors Associated with Mortality in Critically Ill Patients Diagnosed with Hospital Acquired Infections

Objective

Evaluate host and pathogen factors associated with mortality in those with hospital acquired infections (HAI) in a tertiary intensive care unit in Brazil.

Methods

Observational and analytical cohort single center study in a general intensive care unit (ICU) in Northeastern Brazil between January 2016 and August 2018, including those over 18 years of age admitted to the ICU found to have a HAI.

Results

A total of 165 patients were included, with a mean age of 72 years and male predominance (53.3%) and observed mortality of 46%. Mortality in those with HAI was significantly associated with older age, increased ICU length of stay and readmission to the ICU in univariate analysis. Multivariate analysis revealed that development of septic shock and obtundation during ICU admission was significantly associated with an increased risk of death (OR: 6.94, 95% CI 1.23–39.27, OR: 2.48, 95% CI 1.17–5.29, respectively). A trend towards mortality risk was noted in those with increased age and prior cardiovascular disease. Surprisingly, mortality risk was independent of site of infection, type of pathogen and antibiotic resistance. Furthermore, having more than one HAI over the course of the ICU admission did not impact mortality.

Conclusion

Risk of death in those with HAI is associated with obtundation and septic shock, in addition to vasopressor use. Host factors, rather than pathogen-specific characteristics or infecting site, impact risk of death related to HAI in the ICU.

Analyses of the effectiveness of a Brazilian pediatric home care service: a preliminary study

BACKGROUND

Technological advances in health care currently provide better care conditions and have increased survival rates of premature infants, along with increasing the life expectancy of chronically ill children. In this context, the home care service has emerged as an effective tool for the treatment of this group of children. Thus, this preliminary study aimed at evaluating the effectiveness of the Home Care Service (HCS) with regard to pediatric care.

METHODS

A cross-sectional study was performed through a medical record analysis of a tertiary hospital in Minas Gerais/Brazil. Two groups were compared: 36 patients from the HCS (home group) and 13 patients hospitalized with an indication for home care (hospital group). To analyze the effectiveness of HCS, we evaluated the number of readmissions, infection rate, number of procedures, and optimization of beds.

RESULTS

The hospital group presented 6.04 times more infections and was submitted to 6.43 times more procedures. The home group presented lower readmission rates; with 41.66% of children studied not being readmitted and 76.19% of those who needed readmissions did so after more than 30 days from hospital discharge. HCS optimized hospital beds and allowed, over five (5) years, the hospitalization of around 102 patients in the hospital studied.

CONCLUSION

In this preliminary study, HCS reduced the number of procedures and infections compared to hospitalized patients. Moreover, HCS presented lower readmission rates and optimized hospital beds, which could be considered an indication of effectiveness.

Mortality and risks related to healthcare-associated infection

Healthcare-associated infections are a major cause of morbidity-mortality among hospitalized patients. The aim of this epidemiological study was to determine mortality and risks related to death in adult patients with healthcare-associated infections admitted to a teaching hospital in one year. Patient data were collected from infection medical reports. The mortality rate associated with infections was 38.4%, and it was classified as a contributing factor to deaths in 87.1% of death cases. The correlation between healthcare-associated infection and death was statistically significant among clinical patients (41.3%) presenting comorbidities related to the diagnosis (55.8%), cardiovascular infection (62.2%), pneumonia (48.9%), developing sepsis (69.0%), as well as patients who had been colonized (45.2%) and infected (44.7%) by multidrug resistance microorganisms.
