Abstract
INTRODUCTION Nosocomial pneumonia (NP) remains associated with excess morbidity and mortality. The effect of NP on measures such as re-admission at 30 days remains unclear. Moreover, differing types of NP may have varying impacts on re-admissions. METHODS We conducted a multicenter retrospective cohort study within the Premier Research database, a source containing administrative, pharmacy, and microbiology data. We compared NP patients readmitted with pneumonia (RaP) as the principal diagnosis to those readmitted for other reasons (RaO) with respect to the type of NP (ventilator-associated bacterial pneumonia [VABP], ventilated hospital-acquired bacterial pneumonia [vHABP], and non-ventilated HABP [nvHABP]), and characteristics and outcomes of the index hospitalization. RESULTS Among 17,819 patients with NP, 14,123 (79.3%) survived to discharge, of whom 2,151 (15.2%) required an acute readmission within 30 days of index discharge. Of these, 106 (4.9%) were RaP, and the remainder were RaO. At index hospitalization, RaP patients were older (mean age [SD] 67.4 (13.9] vs. 63.0 [15.2] years), more likely medical (44.3% vs. 36.7%), and less chronically ill (median [IQR] Charlson scores (3 [2-5] vs. 4 [2-5]) than persons with RaO. Bacteremia (10.4% vs. 17.5%), need for vasopressors (15.1% vs. 20.0%), dialysis (9.4% vs. 16.5%), and/or sepsis (9.4% vs. 16.5%) or septic shock 14.2% vs. 17.1%) occurred less frequently in the RaP group. With respect to NP type, nvHABP was most common in RaP (47.2%) and VABP in RaO (38.1%). CONCLUSIONS One in seven survivors of a hospitalization complicated by NP requires an acute rehospitalization within 30 days. However, few of these readmissions had a principal diagnosis of pneumonia, irrespective of NP type. Of the 5% of NP subjects with RaP, the plurality initially suffered from nvHABP.

The risk of inappropriate empiric treatment and its outcomes based on pathogens in non-ventilated (nvHABP), ventilated (vHABP) hospital-acquired and ventilator-associated (VABP) bacterial pneumonia in the US, 2012-2019. BMC Infect Dis 2022; 22:775.

Abstract
Background Inappropriate empiric antimicrobial treatment (IET) contributes to worsened outcomes. While IET’s differential impact across types of nosocomial pneumonia (NP: non-ventilated [nvHABP], ventilated [vHABP] hospital-acquired and ventilator-associated [VABP] bacterial pneumonia) is established, its potential interaction with the bacterial etiology is less clear.
Methods We conducted a multicenter retrospective cohort study in the Premier Healthcare Database using an administrative algorithm to identify NP. We paired respective pathogens with empiric treatments. Antimicrobial coverage was appropriate if a drug administered within 2 days of infection onset covered the recovered organism(s). All other treatment was IET. Results Among 17,819 patients with NP, 26.5% had nvHABP, 25.6% vHABP, and 47.9% VABP. Gram-negative (GN) organisms accounted for > 50% of all infections. GN pathogens were ~ 2 × as likely (7.4% vHABP to 10.7% nvHABP) to engender IET than Gram-positive (GP, 2.9% vHABP to 4.9% nvHABP) pathogens. Although rare (5.6% nvHABP to 8.3% VABP), GN + GP infections had the highest rates of IET (6.7% vHABP to 12.9% nvHABP). Carbapenem-resistant GNs were highly likely to receive IET (33.8% nvHABP to 40.2% VABP). Hospital mortality trended higher in the IET group, reaching statistical significance in GN + GP vHABP (47.8% IET vs. 29.3% non-IET, p = 0.016). 30-day readmission was more common with IET (16.0%) than non-IET (12.6%, p = 0.024) in GN VABP. Generally post-infection onset hospital length of stay and costs were higher with IET than non-IET. Conclusions IET is ~ 2 × more common in GN than GP infections. Although the magnitude of its impact varies by NP type, IET contributes to worsened clinical and economic outcomes.

Abstract
The prostatic abscess is a rare complication of a bacterial infection of the prostate. Since the early use of potent antibiotics to treat urinary tract infections, the incidence of the prostatic abscess has declined significantly. In keeping with that, prostatic abscess combined with abscesses in the spleen or other distant organs become an extremely rare but fatal clinical condition. Here, we present a case of prostate and spleen abscess due to multi-drug-resistant gram-negative bacilli without obvious risk factors. The patient initially complained of high-grade fever and dysuria. After screening the source of infection by computed tomography (CT) scans, prostate and spleen abscesses were diagnosed. In addition, extended-spectrum beta-lactamase positive Escherichia coli was detected both in urine and blood culture. The patient was successfully treated by a transurethral resection of the prostate followed by splenic puncture and drainage, as well as intravenous administration of meropenem. Although the prostate abscess combined with spleen abscess was rare, the possibility of dissemination in remote tissues should be taken into consideration before the surgical treatment of prostatic abscesses. The concurrent drainage of multiple abscesses followed by intensive and sensitive antibiotics was safe and effective for indicated patients.

Abstract
OBJECTIVE To explore whether microbiology profiles and the impact of inappropriate empiric treatment differ in the setting of hospital-acquired bacterial pneumonia that requires subsequent mechanical ventilation (vHABP) versus one that does not (nvHABP) versus ventilator-associated bacterial pneumonia (VABP). DESIGN Multicenter retrospective cohort study within Premier Research database, 2014-2019. METHODS We identified cases based on a previously published International Classification of Disease, Ninth Revision/Tenth Revision Clinical Modification (ICD-9/ICD-10-CM) algorithm, and we compared the 3 groups with respect to the bacterial pathogens isolated from their blood, sputum, or lower airway samples, and their respective rates of exposure to inappropriate empiric treatment. Using regression modeling we computed the effect of inappropriate empiric treatment on outcomes. RESULTS Among 17,819 patients who met enrollment criteria, 26.5% had nvHABP, 25.6% vHAPB, and 47.9% VABP. S. aureus (majority methicillin-susceptible) was the most frequently isolated organism, followed P. aeruginosa, K. pneumoniae, and E. coli with variations across the conditions. Rates of carbapenem resistance were highest in VABP (9.1%) and to third-generation cephalosporins in vHABP (14.9%). Patients with nvHABP were most likely to receive inappropriate empiric treatment (8.5%). Although inappropriate empiric treatment was associated with an increase in adjusted postinfection-onset hospital length of stay (2.3 days) and cost ($12,142), its greatest magnitude was in the nvHABP group (4.9 days, $13,147). CONCLUSIONS Substantial microbiologic differences exist among populations who suffer nvHABP, vHABP, and VABP, and inappropriate empiric treatment significantly worsens utilization outcomes. Given the moderate rates of carbapenem resistance and third-generation cephalosporin resistance, all patients require empiric coverage for a range of bacteria, including those targeting extended-spectrum β-lactamase and carbapenem resistance where appropriate.

Abstract
BACKGROUND Initiation of antimicrobial therapy (IAT) with broad-spectrum antibiotics is usual in Intensive Care Unit (ICU) patients with secondary peritonitis. Carbapenems are widely proposed by recent guidelines contrasting with current antibiotic stewardship policies of carbapenem-sparing. However, prognosis of inappropriate IAT remains unclear in these patients and broad-spectrum antibiotics are probably overused. We aimed to assess the role of inappropriate IAT in ICU patients with secondary peritonitis and the use of carbapenems in our IAT regimens. METHODS We performed a retrospective analysis during a six-year period including 131 ICU patients with secondary peritonitis. We collected data concerning comorbidities, source and severity of peritonitis, management of IAT, peritoneal samples and outcome. RESULTS Forty-one patients presented with community acquired peritonitis (CAP) and 90 with postoperative peritonitis (POP). Thirty-seven (28.2%) patients died during ICU stay. IAT was inappropriate in 35 (26.7%) patients. Inappropriate IAT was not associated with reduced survival with respectively 26 (27%) deaths when IAT was adequate and 11 (31.4%) deaths when IAT was inadequate (P=0.87). Inappropriate IAT was not associated with the need of re-operation and duration of ICU stay. Carbapenems were delivered in 29 patients but were only necessary for eight patients without alternative treatment. CONCLUSIONS In our study, inappropriate IAT was not associated with a worse prognosis and carbapenems were overused. Extensive delivery of carbapenems proposed by recent guidelines could be reconsidered in the management of these patients.

Antimicrobial Lessons From a Large Observational Cohort on Intra-abdominal Infections in Intensive Care Units. Drugs 2021; 81:1065-1078.

Abstract
Severe intra-abdominal infection commonly requires intensive care. Mortality is high and is mainly determined by disease-specific characteristics, i.e. setting of infection onset, anatomical barrier disruption, and severity of disease expression. Recent observations revealed that antimicrobial resistance appears equally common in community-acquired and late-onset hospital-acquired infection. This challenges basic principles in anti-infective therapy guidelines, including the paradigm that pathogens involved in community-acquired infection are covered by standard empiric antimicrobial regimens, and second, the concept of nosocomial acquisition as the main driver for resistance involvement. In this study, we report on resistance profiles of Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterococcus faecalis and Enterococcus faecium in distinct European geographic regions based on an observational cohort study on intra-abdominal infections in intensive care unit (ICU) patients. Resistance against aminopenicillins, fluoroquinolones, and third-generation cephalosporins in E. coli, K. pneumoniae and P. aeruginosa is problematic, as is carbapenem-resistance in the latter pathogen. For E. coli and K. pneumoniae, resistance is mainly an issue in Central Europe, Eastern and South-East Europe, and Southern Europe, while resistance in P. aeruginosa is additionally problematic in Western Europe. Vancomycin-resistance in E. faecalis is of lesser concern but requires vigilance in E. faecium in Central and Eastern and South-East Europe. In the subcohort of patients with secondary peritonitis presenting with either sepsis or septic shock, the appropriateness of empiric antimicrobial therapy was not associated with mortality. In contrast, failure of source control was strongly associated with mortality. The relevance of these new insights for future recommendations regarding empiric antimicrobial therapy in intra-abdominal infections is discussed.

Abstract
OBJECTIVES Most patients requiring mechanical ventilation only require it for a short term (< 4 d of mechanical ventilation). Those undergoing prolonged acute mechanical ventilation (≥ 4 d mechanical ventilation) represent a select cohort who face significant morbidity, mortality, and resource utilization. Using administrative codes, we identified prolonged acute mechanical ventilation and short-term mechanical ventilation patients and compared their baseline characteristics, hospital events, and hospital outcomes. DESIGN Retrospective cohort. SETTING Seven-hundred eighty-seven acute care hospitals, United States, contributing data to Premier database, 2014-2018. PATIENTS Patients on mechanical ventilation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Among 691,961 patients meeting the enrollment criteria, 266,374 (38.5%) received prolonged acute mechanical ventilation. At baseline, patients on prolonged acute mechanical ventilation were similar to short-term mechanical ventilation in age (years: 62.0 ± 15.8 prolonged acute mechanical ventilation vs 61.7 ± 17.2 short-term mechanical ventilation), gender (males: 55.6% prolonged acute mechanical ventilation vs 53.9% short-term mechanical ventilation), and race (white: 69.1% prolonged acute mechanical ventilation vs 72.4% short-term mechanical ventilation). The prolonged acute mechanical ventilation group had a higher comorbidity burden than short-term mechanical ventilation (mean Charlson Score 3.5 ± 2.7 vs 3.1 ± 2.7). The prevalence of vasopressors (50.3% vs 36.9%), dialysis (19.4% vs 10.3%), severe sepsis (20.3% vs 10.3%), and septic shock (33.5% vs 15.9%) was higher in prolonged acute mechanical ventilation than short-term mechanical ventilation. Hospital mortality (29.75% vs 21.1%), combined mortality, or discharge to hospice (37.2% vs 25.3%), extubation failure (12.3% vs 6.1%), tracheostomy (21.6% vs 4.5%), development of Clostridium difficile (4.5% vs 1.7%), and incidence density of ventilator-associated pneumonia (2.4/1,000 patient-days vs 0.6/1,000 patient-days) were all higher in the setting of prolonged acute mechanical ventilation than short-term mechanical ventilation. Median (interquartile range) post mechanical ventilation onset length of stay (13 [8-20] vs 4 d [1-8 d]) and hospital costs ($55,014 [$35,051-$88,007] vs $20,120 [$12,071-$34,915] were higher in prolonged acute mechanical ventilation than short-term mechanical ventilation. CONCLUSIONS Over one-third of all hospitalized patients on mechanical ventilation require it for greater than or equal to 4 days. Prolonged acute mechanical ventilation patients exhibit a higher burden of both chronic and acute illness and experience higher rates than those on short-term mechanical ventilation of hospital-acquired complications and worse clinical and economic outcomes.

Abstract
PURPOSE OF REVIEW Timely and adequate management are the key priorities in the care of peritonitis. This review focuses on the cornerstones of the medical support: source control and antiinfective therapies. RECENT FINDINGS Peritonitis from community-acquired or healthcare-associated origins remains a frequent cause of admission to the ICU. Each minute counts for initiating the proper management. Late diagnosis and delayed medical care are associated to dramatically increased mortality rates. The diagnosis of peritonitis can be difficult in these ICU cases. The signs of organ failures are more relevant than biological surrogates. A delayed source control and a late anti-infective therapy are of critical importance. The quality of source control and medical management are other key elements of the prognosis. The conventional rules applied for sepsis are applicable for peritonitis, including hemodynamic support and anti-infective therapy. Growing proportions of multidrug resistant pathogens are reported from surgical samples, mainly related to Gram-negative bacteria. The increasing complexity in the care of these critically ill patients is a strong incentive for a multidisciplinary approach. SUMMARY Early clinical diagnosis, timely and adequate source control and antiinfective therapy are the essential pillars of the management of peritonitis in ICU patients.

Abstract
Background Complicated intra-abdominal infections (cIAIs) remain a leading cause of death in surgical wards, in which antibiotic treatment is crucial. We aimed to compare the efficacy and safety of novel β-lactam/β-lactamase inhibitors (BL/BLIs) in combination with metronidazole and carbapenems in the treatment of cIAIs. Methods A comprehensive search of randomized controlled trials (RCTs) was performed using Medline, Embase, and Cochrane Library, which compared the efficacy and safety of novel BL/BLIs and carbapenems for the treatment of cIAIs. Results Six RCTs consisting of 2254 patients were included. The meta-analysis showed that novel BL/BLIs in combination with metronidazole had a lower clinical success rate (risk difference [RD], -0.05; 95% CI, -0.07 to -0.02; I 2 = 0%) and a lower microbiological success rate (RD, -0.04; 95% CI, -0.08 to -0.00; I 2 = 0%). No difference was found between the 2 groups in incidence of adverse events (RD, 0.02; 95% CI, -0.01 to 0.06; I 2 = 0%), serious adverse events (SAEs; RD, 0.01; 95% CI, -0.02 to 0.03; I 2 = 0%), or mortality (RD, 0.01; 95% CI, -0.00 to 0.02). However, ceftazidime/avibactam had a higher risk of vomiting (RD, 0.03; 95% CI, 0.01 to 0.05; I 2 = 47%), and the ceftolozane/tazobactam subgroup showed a higher incidence of SAEs (RD, 0.12; 95% CI, 0.01 to 0.03). Conclusions The efficacy of novel BL/BLIs in combination with metronidazole was not as high as that of carbapenems. Although no significant differences were found with respect to overall adverse events, SAEs, or mortality, the novel BL/BLIs has a higher risk of vomiting. We still need to be cautious about the clinical application of a new anti-infective combination. Trial registration PROSPERO ID: 42020166061.

Abstract
Background Expert guidelines discourage use of antipseudomonal β-lactams and fluoroquinolones in lower-risk patients with community-acquired complicated intra-abdominal infection (CA cIAI). Compliance with these recommendations across US hospitals is unclear. This study sought to determine treatment patterns and associated outcomes among adult hospitalized lower-risk patients with CA cIAI. Methods A study using data from the Premier Healthcare Database (10/2015–12/2017) was performed. Inclusion criteria: age ≥18 years; hospitalized; had a cIAI at admission; and received antibiotics within the first 4 hospital days. Patients were excluded if they were high risk, were transferred from another health care facility, had a recent hospital admission, or received dialysis within 30 days of admission. Empiric antibiotic treatment patterns and associated outcomes were quantified. Results Overall, 46 722 (66%) patients with cIAIs met the lower-risk CA IAI study criteria. Among lower-risk CA IAI patients, the mean (SD) age was 53.4 (18.2) years, and 71% had a Charlson Comorbidity Index score of 0. The most common diagnosis was acute appendicitis with peritonitis (59.7%). Among lower-risk CA IAI patients, 54% received piperacillin/tazobactam, 20% received a fluoroquinolone (FQ), 11% received ceftriaxone, and 7% received ampicillin/sulbactam. Overall, the median hospital length of stay was 4 days and median costs were $12 345 USD. Nearly 90% of patients were discharged home, and <1% died. Outcomes were similar across all empiric treatments received. Conclusions Overuse of antipseudomonal β-lactams and fluoroquinolones was commonplace among lower-risk CA IAI patients. These findings can serve as the basis for an antimicrobial stewardship initiative in hospitals aspiring to reduce the use of broad-spectrum antibiotics.
