A study of some factors associated with wound infection
Abstract:
Five hundred and four surgical patients were studied at Princess Basma Hospital, North Jordan, during the period April 1984-January 1985. The overall postoperative wound infection rate was 3.6%. In clean surgery 1.1% of wounds were infected and in potentially contaminated and contaminated surgery the infection rate was 3.3% and 18.5% respectively. Major organisms isolated from infected wounds were Staphylococcus aureus (55.5%), Escherichia coli (16.6%), Proteus vulgaris (11.1%), Pseudomonas aeruginosa, Enterobacter aerogenes and Aeromonas hydrophilia, each with 5.6%. Use of a wound drain, duration of operation and carriage of Staph. aureus by the patient were associated with a higher frequency of wound infection.
Insights
This study on surgical wound infections in Jordan found an overall rate of 3.6%. Staphylococcus aureus was the most common pathogen, and factors like wound drains increased infection risk.
Area of Science:
- Medical Microbiology
- Surgical Infections
- Epidemiology
Background:
- Postoperative wound infections (PWI) represent a significant challenge in surgical patient care.
- Understanding the epidemiology and causative agents of PWI is crucial for implementing effective prevention strategies.
- Previous studies have highlighted variations in PWI rates and microbial profiles across different settings.
Purpose of the Study:
- To determine the incidence and microbial spectrum of postoperative wound infections.
- To identify risk factors associated with surgical site infections in a Jordanian hospital.
- To provide data for improving infection control measures in surgical settings.
Main Methods:
- A prospective study involving 504 surgical patients was conducted at Princess Basma Hospital, North Jordan.
- Data collection covered the period from April 1984 to January 1985.
- Wound infection rates were analyzed based on surgical wound classification (clean, potentially contaminated, contaminated).
Main Results:
- The overall postoperative wound infection rate was 3.6%.
- Infection rates varied significantly by wound class: 1.1% (clean), 3.3% (potentially contaminated), and 18.5% (contaminated).
- Staphylococcus aureus (55.5%) was the predominant organism, followed by Escherichia coli (16.6%) and Proteus vulgaris (11.1%).
Conclusions:
- Surgical wound infection rates are influenced by wound classification and specific microbial agents.
- Factors such as the use of wound drains, prolonged operation duration, and patient carriage of Staphylococcus aureus are associated with increased infection risk.
- These findings underscore the importance of targeted infection control strategies in surgical practice.
