A 14-month study of severe non-wound infectious complications in general surgery
Abstract:
A retrospective study of serious non-wound infectious complications in general surgery during at 14-month period is reported. A prospective study on wound infections in available from the same institution and period. Septicemia, intraabdominal and intrathoracal abscesses and rare cases of osteomyelitis occurred in 1.3% of all treated patients, whereas postoperative wound infection developed in 7.5% of primarily non-infected patients. Mortality was significantly higher among patients with serious infections than in all patients nursed during the same period. Severe postoperative infectious complications was in fact the third most common cause of death and accounted for 14% of the mortality of the clinic. This rate rises to close to 50% when death from incurable disease is excluded. Septicemia carried a significantly higher mortality rate than intraabdominal abscesses. The risk of a serious infection developing was significantly higher in operations on the small or large intestine than after appendectomies or biliary operations. Gram negative bacteria dominated, especially in cases with a fatal outcome. Contributing factors such as malignancy, preoperative infection or macroscopic peroperative wound soiling, were more common in patients where a serious infectious complication developed postoperatively.
Insights
Serious infections like septicemia and abscesses affected 1.3% of general surgery patients, with higher mortality. These severe complications were the third leading cause of death, highlighting a significant surgical patient risk.
Area of Science:
- General Surgery
- Infectious Diseases
- Surgical Outcomes
Background:
- Postoperative infectious complications pose a significant threat to patient recovery and survival.
- Understanding the incidence and impact of both wound and non-wound infections is crucial for improving surgical care.
Purpose of the Study:
- To evaluate the incidence and mortality of serious non-wound infectious complications in general surgery.
- To compare the rates of serious infections with postoperative wound infections.
- To identify risk factors and common pathogens associated with severe surgical site infections.
Main Methods:
- A retrospective analysis of serious non-wound infections over a 14-month period.
- A concurrent prospective study on wound infections from the same institution and timeframe.
- Comparison of mortality rates between patients with serious infections and the overall patient population.
Main Results:
- Serious non-wound infections (septicemia, abscesses, osteomyelitis) occurred in 1.3% of patients.
- Postoperative wound infections developed in 7.5% of patients.
- Severe infections significantly increased mortality, ranking as the third most common cause of death (14% of total mortality).
- Septicemia had a higher mortality rate than intraabdominal abscesses.
- Operations on the small or large intestine carried a higher risk of serious infection compared to appendectomies or biliary operations.
- Gram-negative bacteria were predominant, particularly in fatal cases.
- Malignancy, preoperative infection, and wound soiling were linked to increased risk of severe complications.
Conclusions:
- Severe postoperative infectious complications represent a major cause of mortality in general surgery.
- Risk stratification and preventative measures are essential, especially for high-risk surgeries and patients.
- Targeted antimicrobial strategies against Gram-negative bacteria may be necessary.
