The impact of initial antibiotic treatment failure: real-world insights in patients with complicated, health care-associated intra-abdominal infection.

PURPOSE: The RECOMMEND study (NCT02364284; D4280R00005) assessed the clinical management patterns and treatment outcomes associated with initial antibiotic therapy (IAT; antibiotics administered ≤48 hours post-initiation of antibiotic therapy) for health care-associated infections across five countries. PATIENTS AND METHODS: Data were collected from a retrospective chart review of patients aged ≥18 years with health care-associated complicated intra-abdominal infection (cIAI). Potential risk factors for IAT failure were identified using logistic regression analyses. RESULTS: Of 385 patients with complete IAT data, bacterial pathogens were identified in 270 (70.1%), including Gram-negative isolates in 221 (81.9%) and Gram-positive isolates in 92 (34.1%). Multidrug-resistant (MDR) pathogens were identified in 112 patients (41.5% of patients with a pathogen identified). IAT failure rate was 68.3% and in-hospital mortality rate was 40.8%. Multivariate regression analysis demonstrated three factors to be significantly associated with IAT failure: patients admitted/transferred to the intensive care unit during index hospitalization, isolation of an MDR pathogen and previous treatment with ß-lactam antibiotics. CONCLUSION: We reveal the real-world insights into the high rates of IAT failure and mortality observed among patients with cIAI. These data highlight the challenges associated with choosing IAT, the impact of MDR pathogens on IAT outcomes and the importance of tailoring IAT selection to account for local epidemiology and patient history.

The impact of initial antibiotic treatment failure: Real-world insights in healthcare-associated or nosocomial pneumonia.

OBJECTIVES: To assess real-world treatment patterns and clinical outcomes associated with initial antibiotic therapy (IAT, antibiotics received ≤ 48 h post-initiation of antibiotic therapy), including level of IAT failure, and potential risk factors for IAT failure in healthcare-associated infections. METHODS: Data were obtained from medical records of adult patients hospitalized with healthcare-associated pneumonia (HCAP) and nosocomial pneumonia (NP), including ventilator-associated pneumonia, from 1 July 2013 to 30 June 2014 in Brazil, France, Italy, Russia and Spain during the retrospective, observational study, RECOMMEND (NCT02364284; D4280R00005). Potential risk factors for IAT failure were explored using logistic regression analyses. RESULTS: Mean (standard deviation) age and Deyo-Charlson Comorbidity Score were 66.0 (16.2) years and 2.4 (2.4), respectively (N = 451). Most patients (62.5%) received monotherapy. Mean (standard deviation) duration of IAT was 8.8 (7.2) days. Multidrug-resistant (MDR) pathogens were identified in 52.4% of patients with ≥ 1 pathogen isolated (154/294). IAT failure was recorded in 72.5% of patients and was significantly associated with isolation of a MDR pathogen and country using multivariate analyses. CONCLUSIONS: Real-world data demonstrate the burden of HCAP/NP, with high rates of IAT failure. The association of IAT failure with MDR pathogens highlights the urgent need to understand and account for local prevalence of MDR pathogens when selecting IAT for the management of HCAP/NP.

The impact of initial antibiotic treatment failure: Real-world insights in patients with complicated urinary tract infection.

OBJECTIVES: RECOMMEND (NCT02364284; D4280R00005) assessed treatment patterns and outcomes associated with initial antibiotic therapy (IAT; antibiotics received <48 h post-initiation of antibiotic therapy) in healthcare-associated infections across five countries. METHODS: Data from medical records of hospitalized patients aged ≥18 years with healthcare-associated complicated urinary tract infections (cUTI) are presented. Univariate and multivariate logistic regression analyses identified potential risk factors associated with IAT failure. RESULTS: Mean (SD) age was 68.7 (17.4) years (n = 408). In patients with microbiological documentation (357/408), Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa were most common (47.1%, 21.6% and 11.8%, respectively); 46.1% of patients had a multidrug resistant (MDR) pathogen isolated. Most patients received monotherapy IAT (72.5%). Mean IAT duration was 7.8 days. IAT failure, in-hospital mortality, and mortality 30-day post-discharge were 54.4%, 35.0% and 37.3%, respectively. IAT failure was associated with age, Deyo-Charlson comorbidity score, country, MDR status and ICU admission in the univariate analysis; and country and age in the multivariate analysis. CONCLUSIONS: This study provides real-world insights into the high rates of IAT failure and morbidity observed in patients with cUTI. Further study is imperative to understand the epidemiology of cUTI, support appropriate IAT selection and management, and reduce the burden of this disease.
