Background:
Current guidelines suggest antibiotics prophylaxis is not necessary for patients with orthopedic prosthetics undergoing gastrointestinal endoscopy. Clinical evidence to support this recommendation is lacking.
Aims:
To analyze the association between inpatient gastrointestinal endoscopy and prosthetic joint infection (PJI) in patients with a recent arthroplasty.
Methods:
We included patients admitted from July to October of each calendar year (index admissions) who had an arthroplasty in the same calendar year prior to the index admission. We followed the occurrence of PJI for 60 days after the index admission. Only admissions from July to October were chosen as index admissions, and the follow-up period was limited to 60 days because the database structure prohibits the analysis of events in different calendar years. We compared the rate of 60-day PJI between those who had gastrointestinal endoscopy on index admissions to those who had not. We excluded patients aged less than 18 years, who died on index admission, or had any infection in the same calendar year before or during the index admission.
Results:
Of 1,831,218 patients with arthroplasty, 88,345 met the inclusion criteria, out of which 5,855 had gastrointestinal endoscopy. The rate of 60-day PJI in those who had endoscopy was 0.23%, and in those who had not was 0.52% (P < 0.001). EGD without excision (adjusted odds ratio [95% confidence interval]: 0.20 [0.03-1.42], P = 0.107), EGD with excision (0.58 [0.21-1.60], P = 0.295), colonoscopy without excision (0.43 [0.11-1.72], P = 0.233), colonoscopy with excision (0.31 [0.04-2.21], P = 0.241), and PEG/PEJ (0.38 [0.05-2.71], P = 0.337) were not associated with risk of 60-day PJI. We found no PJI cases in patients underwent esophageal dilation, ERCP, and EUS with FNA.
Conclusions:
Gastrointestinal endoscopy in hospitalized patients with a recent previous arthroplasty is not associated with an increased risk of 60-day prosthetic joint infection.
