Analysis of incidence of postoperative wound infection in closed fractures treated by surgical fixation – A prospective study

ABSTRACT:

Background

In orthopaedic surgery where metallic implants are used, surgical site infection (SSI) is a significant complication as it increases the postoperative morbidity and mortality, prolongs hospital stay, and increases the hospital costs. Therefore, understanding the incidence of SSI in various healthcare settings would help us analyse the contributing factors and improve healthcare. Since the rates of SSI in various orthopaedic settings in India are lacking, this study aimed at analysing them and various associated factors in a tertiary medical institute in India.

Materials and methods

This study was a prospective cohort study carried out on 100 orthopaedic patients who underwent surgical fixation for closed fractures, with a follow-up period of one year. The incidence of SSI and the factors associated with them were analysed.

Results

The overall incidence of SSI in our study was 5% (5 cases). The maximum incidence was seen in the age group 51–60 years (40% of the infections). Regarding the duration of preoperative hospital stay, the incidence of SSI was 6.85% when the patients stayed for more than 10 days, whereas the incidence was only 1.66% when the patients stayed for less than or equal to 10 days. Among the diabetics, the incidence of infection was found to be 7.69% (1 out of 13 diabetics). Regarding the operative duration, while cases which took more than 1.5 hours of operative duration had the highest infection rate (60% of the infections), none of the cases which took less than an hour to operate got infected. Among the infective organisms isolated, 60% cases had Staphylococcus aureus, 20% had Proteus vulgaris and another 20% had Klebsiella pneumoniae infection.

Conclusions

Age greater than 50 years, a prolonged preoperative hospital stay more than 10 days, presence of diabetes, a prolonged surgical procedure more than 1.5 hours, and were found to be at a higher risk of SSI in our study. Highlights • Surgical site infection (SSI) in orthopaedic surgery can lead to chronic infection or osteomyelitis.• Specific data about SSI in orthopaedics in India are lacking.• Our study highlighted the SSI related factors in orthopaedics in India.• Higher age, longer preoperative hospital stay, prolonged surgical procedure and diabetes were found associated.

Project description:BackgroundTrauma is a major public health problem, particularly in India due to the country's rapid urbanization. Tibia fractures are a common and often complicated injury that is at risk of infection following surgical fixation. The primary objectives of this cohort study were to determine the incidence of infection within one year of surgery and to describe the distribution of infections by location and time of diagnosis for tibia fractures in India.MethodsWe conducted a multi-center, prospective cohort study. Patients who presented with an open or closed tibia fracture treated with internal fixation to one of the participating hospitals in India were invited to participate in the study. Participants attended follow-up visits at 3, 6, and 12 months post-surgery, where they were assessed for infections, fracture healing, and health-related quality of life as measured by the EurQol-5 Dimensions (EQ-5D).ResultsSeven hundred eighty-seven participants were included in the study and 768 participants completed the 12 month follow-up. The overall incidence of infection was 2.9% (23 infections). The incidence of infection was 1.6% (10 infections) in closed and 8.0% (13 infections) in open fractures. There were 7 deep and 16 superficial infections, with 5 being early, 7 being delayed, and 11 being late infections. Intra-operative antibiotics were given to 92.1% of participants and post-operative antibiotics were given to 96.8% of participants. Antibiotics were prescribed for an average of 8.3 days for closed fractures and 9.1 days for open fractures. Infected fractures took significantly longer to heal, and participants who had an infection had significantly lower EQ-5D scores.ConclusionsThe incidence of infection within this cohort is similar to those seen in developed countries. The duration of prophylactic antibiotic use was longer than standard practice in North America, raising concern for the potential development of antibiotic resistant microbes within Indian orthopaedic settings. Future research should aim to identify the best practice for antibiotic use in India to ensure that antibiotic usage patterns do not lead to unnecessary overuse, while maintaining a low incidence of infection.Trial registrationNCT01691599 , September 17, 2012.

Project description:BackgroundThis study aimed to identify the threshold for success in supracondylar humeral fracture surgery by describing the learning curve for beginners and exploring the relationship between the learning curve and the prognosis of supracondylar fractures of the humerus.MethodsSurgical information was collected of the first 100 humeral fractures treated by four pediatric orthopedic surgeons. The relationship between operation time, wire placement success rate, and surgical experience was determined using the restricted cubic strip (RCS). The inflection point in the curve and other risk factors that may affect fracture prognosis were collected and subjected to multiple logistic regression to clarify the relationship between the learning curve and prognosis of supracondylar fractures of the humerus. After the training, the four fresh surgeons were interviewed in the form of questionnaires to get feedback from the trainees.ResultsA total of 400 supracondylar fractures of the humerus from four pediatric orthopedists were included in the study. On an RCS analysis, 65 surgical experiences were the inflection point of the learning curve. Before and after these 65 surgical experiences, there were significant differences in the patients' anatomical reduction (186 vs. 122, P < 0.001), conversion to incision (33 vs. 6, P = 0.008), and supervising physician guidance (28 vs. 2, P < 0.001). In the multiple logistic regression analysis, functional recovery after supracondylar fractures of the humerus was significantly associated with surgical experience, intraoperative conversion to incision, and post-operative infection. Four surgeons and a supervisor were interviewed. They believed that self-confidence establishment requires the experience accumulation of about 30 operations. The most critical surgical technique is the reduction of fractures.ConclusionsAlthough the accumulated experience of 30 operations can establish the self-confidence of trainers, fresh surgeons must accumulate experience with 65 operations to master closed reduction and internal fixation for supracondylar fractures. Surgical experience significantly impacts the post-operative recovery of patients with fractures.Level of evidenceLevel III.
