Introduction:
The increase of antimicrobial resistances, has affected the efficacy of antimicrobial triple therapy, increasing appendicitis morbidity. We decided to change to a fast-track protocol of 72 hours of Cefuroxime-Metronidazol or Ertapenem.
Aim:
to know if our infectious morbidity rate has improved and if early dischargement is possible.
Material And Methods:
Analytic historic cohort study: Historical cohort (HC): patients intervened of appendicitis between October 2005 and October 2006. Current cohort (CC): started in June 2007. A data collection protocol is designed for both groups. Homogeneity among cohorts is proved and data are analysed (a=0,05). Statistics are analyzed by SPSS 15.0.
Results:
226 patients were controlled, being 110 complicated appendicitis (HC: 61/135; AC: 49/91). There are no differences among cohorts about evolution time, temperature and leukocytes rate at admission, interval to intervention, use of laparoscopy, drainage or antimicrobial prophylaxis. There is difference about the use of pre-surgical ultrasound. Admission rate has been reduced in 2.82 days, from 8.41 days in HC to 5.58 with the new antimicrobial protocol (median 7 to 4). The relative risk of developing intraabdominal abscess is 0.366 (HC: 15.7%; CC: 6.4%) (p=0.145) and readmission rate has been reduced from 9.8% to 0% (p=0.028). In 33% of cultures we have found different levels of antimicrobial resistance. No Enterococcus has been isolated.
Conclusions:
1) Infectious morbidity rate has decreased with the new therapy. 2) Antimicrobial resistance and new antibiotics have exceeded Triple antimicrobial therapy. 3) It is possible an early dischargement in perforated appendicitis without an increasing of readmission rate. 4) We must know the bacterial flora in order to adapt our antibiotic therapy.
Insights
A new 72-hour antibiotic protocol for appendicitis significantly reduced infectious morbidity and intra-abdominal abscesses. This fast-track approach allows for early patient discharge without increasing readmission rates, addressing rising antimicrobial resistance.
Area of Science:
- Infectious Diseases
- Surgical Infections
- Antimicrobial Stewardship
Context:
- Rising antimicrobial resistance challenges traditional appendicitis treatment.
- Triple antimicrobial therapy efficacy is declining, increasing patient morbidity.
- A fast-track protocol using Cefuroxime-Metronidazole or Ertapenem was implemented.
Purpose:
- To evaluate the impact of a new fast-track antibiotic protocol on infectious morbidity rates.
- To determine the feasibility of early patient discharge in appendicitis cases.
- To assess changes in infectious complications and readmission rates.
Summary:
- An analytic historic cohort study compared patients before and after protocol implementation.
- The new protocol reduced hospital stay by 2.82 days and intra-abdominal abscess risk (RR 0.366).
- Readmission rates decreased significantly from 9.8% to 0%, with no increase in complications.
Impact:
- The new protocol effectively decreased infectious morbidity in appendicitis patients.
- Early discharge is feasible for perforated appendicitis without compromising patient safety.
- Understanding local bacterial flora is crucial for optimizing antibiotic therapy in appendicitis.
