Cefoxitin Plus Doxycycline Versus Clindamycin Plus Gentamicin in Hospitalized Pelvic Inflammatory Disease Patients: An Experience from A Tertiary Hospital

Objective: To compare the length of hospital stay (LOS) and surgical rate in patients hospitalized with pelvic inflammatory disease (PID) who received either cefoxitin plus doxycycline regimen or clindamycin plus gentamicin regimen. Methods: Medical records of patients hospitalized with PID from 2004 to 2011 were reviewed. Study population was women aged 14-40 years old who had a first-time, admitted diagnosis and a discharged diagnosis of PID. Patients who had prior hysterectomy, bilateral salpingectomy and were not sexually active were excluded. The patients received either intravenous cefoxitin (2 grams every 6 hours) plus oral doxycycline (100 mg twice a day) regimen or intravenous clindamycin (900 mg every 8 hours) plus gentamicin (240 mg once daily) regimen. Outcomes of interest were LOS and surgical rate. Results: Of 252 eligible participants, 141 (55.95%) received cefoxitin plus doxycycline and 111 (44.05%) received clindamycin plus gentamicin. The patients receiving cefoxitin plus doxycycline had statistically significant lower age and less number of cases of tubo-ovarian abscess (TOA) (P<0.05). Logistic regression showed the similar LOS and surgical rate in both groups after adjusted with age and TOA. No severe adverse effect was identified in both regimens. Conclusion: Cefoxitin plus doxycycline regimen appears as effective as clindamycin plus gentamicin regimen for treating hospitalized PID patients in terms of LOS, surgical rate and safety profile
