Background: The estimated number of in-hospitals deaths due to adverse events is often different when using data from deceased patients compared with that of a population experiencing adverse events.
Methods: The study was conducted at three hospitals in the Bergen Hospital Trust, including a 950-bed university hospital. The objective was to study the reported deaths and investigate the probable number of deaths caused by adverse events.
Article Synopsis
- Streptococcus pyogenes, commonly known as group A streptococcus (GAS), is the primary cause of necrotizing soft tissue infections (NSTI), although other strains like Streptococcus dysgalactiae may also play a role.
- In a study conducted in western Norway between 2000-2009, 70 cases of NSTI were analyzed, with 61 due to GAS and 9 from group C and G streptococci (GCS/GGS).
- The study found that while GAS infections had an 11% fatality rate, GCS/GGS infections were more severe with a 33% fatality rate, largely affecting older patients with pre-existing health issues and showing significant differences in disease
A comparison of SAPS II and SAPS 3 in a Norwegian intensive care unit population.
Acta Anaesthesiol Scand
May 2009
Article Synopsis
- The study compared the effectiveness of two severity scoring systems, SAPS II and SAPS 3, in predicting mortality among ICU patients in Norway, as previous validations in Scandinavia were lacking.
- Data was collected from nearly 1,900 adult ICU patients, and findings showed that while both SAPS II and SAPS 3 overestimated mortality rates, the SAPS 3 equations had better calibration and performance metrics.
- Overall, SAPS 3 was deemed satisfactory in its performance compared to SAPS II, but both systems are still recommended for further customization based on larger patient data.
The effect of tracheostomy on outcome in intensive care unit patients.
Acta Anaesthesiol Scand
January 2006
Background: Percutaneous dilatation tracheostomy (PDT) is increasingly being used in the intensive care unit (ICU), and has probably increased the number of procedures performed. The primary aim of this study was to document the short- and long-term outcome of patients with a tracheostomy performed during an ICU stay.
Methods: Patients in our ICU who underwent an unplanned tracheostomy between 1997 and 2003 were included in this analysis.
Background: In order to control the quality of the medical report after a hospital stay with regards to the stay in the intensive care unit (ICU), and to cheque for correct DRG grouping, this study of 428 patients treated in our ICU in 2003 was conducted.
Material And Methods: All ICU patients from 2003 were found in our database, which includes specific ICD-10 diagnosis and specific ICU procedures. The medical record summarising the hospital stay (epicrisis) was retrieved for each patient from the hospital's electronic patient files and controlled for correct information regarding the ICU stay.
