IMPACT IN ANTIBIOTIC USE AFTER IMPLEMENTATION OF AN ANTIMICROBIAL STEWARDSHIP PROGRAM AND A JOINT PROTOCOL WITH ELECTRONIC PRESCRIPTION FOR APPENDICITIS/PERITONITIS IN PEDIATRICS
Abstract
Backgrounds:
Initial antibiotic treatment in appendicitis/peritonitis significantly reduces wound infection and intra-abdominal abscess formation in patients with gangrenous or perforated appendicitis. Randomized controlled trials have shown that the use of lower-spectrum antibiotic combinations is as effective in preventing abscesses or surgical wound infections as broad-spectrum regimens.
Methods
Observational, retrospective study of patients <16 years of age admitted for appendicitis and/or peritonitis from Jan/2014 to Dec/2019 in a tertiary university hospital in Madrid, Spain. Three study periods were established: P1 2014-2015 (before Antimicrobial Stewardship Programme (ASP)), P2 2016-2018 (ASP implemented) and P3 Jan/2019-Dec/2019 (ASP and implementation of an appendicitis/peritonitis protocol with electronic prescription, including lower-spectrum antibiotic combinations and selected and clinically guided use after surgery). Antimicrobial use was analysed with the days of therapy/1000 admissions days (DOT/1000) and start of treatment/1000 hospital admissions (SOT/1000).
Results:
During the study period a total of 1619 patients met inclusion criteria. The proportion of patients without antibiotic therapy after surgery during P1, P2 and P3 was 5.6%, 3.7%, and 38.6% respectively. [C1] The evolution of antibiotic use expressed by DOT / 1000 is shown in Figure 1. SOT/1000 of ampicillin, gentamicin and metronidazole rose from 162, 190 and 190 in 2014 to 386, 402 and 409 in 2019. DOT/1000 of meropenem drop to 64.85 in 2014 to 0 in 2019.
Conclusions/Learning Points:
The implementation of an ASP and a low-spectrum antibiotic protocol with electronic prescribing, reduced the antimicrobial use in children with appendicitis/peritonitis. The proportion of patients without antibiotic therapy after surgery increased and the use of carbapenems and other broad-spectrum antibiotics was reduced after the intervention. These improvements were observed when an electronically available protocol was added to the ASP implementation.
EPIDEMIOLOGY AND OUTCOMES OF GRAM-NEGATIVE BACTEREMIA IN A TERTIARY UNIVERSITY HOSPITAL IN MADRID, SPAIN (2018-2020).
Abstract
Backgrounds:
Gram-negative bacteremia (GNB) is associated with a significant rate of morbidity and mortality in adults. Moreover, resistances to antibiotics are increasingly described in surveillance reports. However, the epidemiology and outcomes of GNB in children are not well known. We aimed to analyze GNB bacteremia in pediatric patients in a tertiary hospital over a three years period.
Methods
A retrospective, observational study of bacteremia episodes caused by Enterobacteriaceae or non-fermentative GNB in pediatric patients between January of 2018 and December 2020 in a Tertiary Hospital from Madrid, Spain, was carried out through microbiology charts and clinical records. Demography, comorbidities, risk factors and infection characteristics were recorded, and bacterial strain and antibiotic resistance were registered. Three primary endpoints were defined: mortality, bacteremia persistence and recurrence. A statistical analysis was applied to assess differences in these outcomes according to the risk factors. A multivariable logistic regression analysis was used to assess the association between bacteria resistance and mortality.
Results:
One hundred eighteen cases of GNB in one hundred and seven patients were included. The characteristics of the patients are shown in Table 1. In fifty-three cases (44.9%) GNB presented resistance to at least one group of antibiotic and in nine (7.6%) were multidrug-resistant (Table 1). The incidence of resistance rates by years were stable. Indwelling urinary catheterization was a risk factor associated to mortality [OR 3.48 (1.20-10.6)] and parenteral nutrition was related to persistent bacteremia [OR 7.69 (1.1-209)]. No relation between drug resistance and mortality was observed in multivariable analysis.
Conclusions/Learning Points:
GNB represented an important problem in our institution, mainly related to neonatal intensive care and heart surgery. Antibiotic resistance was common. Patients that carried invasive care devices presented higher rates of bacteremia persistence and mortality.
