Do we use antibiotics judiciously enough? A study in Accident & Emergency Department of tertiary care hospital in Pakistan

摘要

Objective: To determine whether antibiotics are necessary for all minor wounds presenting to the Accident and Emergency Department at a tertiary care Centre in Pakistan. Methods: One hundred and five patients presenting to the Accident & Emergency Department, Jinnah Postgraduate Medical Centre, Karachi, with open wounds were included in the study and divided into two: Groups A (study) and B (control), with Group-A receiving conservative therapy. Eighty-four patients were included in the final analysis as the rest were lost to follow up. Follow up was done after one week to see how many patients had developed infection. Results: The average age of patients was 27.3 +/-9.7 years with similar baseline characteristics. From these, 51% had superficial wounds; average number of wounds was 1.63 +/-0.99, with an average length of 2.7 +/-1.6 cm. A total of 10 out of 84 patients developed infection at 7-10 days after presentation to the A&E. From these, 3 patients receiving conservative treatment (A, 10%, OR=0.107), and seven patients receiving prophylactic antibiotics (B, 12.96%, OR=0.149) developed an infection. Calculated odds ratio for increased risk of infection in Group-A = 0.72. Conclusion: A conservative approach to antibiotic prescription for minor trauma may be appropriate despite absence of strict asepsis during emergency wound care.
