Risk factors and economic burden for community-acquired multidrug-resistant organism-associated urinary tract infections: A retrospective analysis.

The spread of multidrug-resistant organisms (MDROs) has resulted in a corresponding increase in the incidence of urinary tract infections (UTIs). The risk factors and hospitalization burden for community-acquired MDRO-associated UTIs are discussed herein. This retrospective study included 278 patients with community-based MDRO-associated UTIs from January 2020 to January 2022. The MDRO (n = 139) and non-MDRO groups (n = 139) were separated based on drug susceptibility results. Community-based MDRO-associated UTIs mainly occurred in the elderly and frail patients with a history of invasive urinary tract procedures. The MDRO group imposed a greater economic burden compared to the non-MDRO group. Independent risk factors for community-based MDRO-associated UTIs were as follows: white blood cell (WBC) count > 10.0 × 109/L (OR = 2.316, 95% CI = 1.316-3.252; P = .018); ≥3 kinds of urinary tract obstructive diseases (OR = 1.720, 95% CI = 1.004-2.947; P = .048); use of 3rd generation cephalosporins (OR = 2.316, 95% CI = 1.316-4.076; P = .004); and a history of invasive urologic procedures (OR = 2.652, 95% CI = 1.567-4.487; P < .001). Days of hospitalization, antibiotic use, and bladder catheter use were significantly greater in the MDRO group than the non-MDRO group (P < .05).

Monitoring Multidrug-Resistant Acinetobacter baumannii Infections in the Neurosurgery ICU Using a Real-Time Surveillance System.

Multidrug-resistant Acinetobacter baumannii (MDR-AB) infections are becoming increasingly common. The Real-Time Nosocomial Infection (NI) Surveillance System (RT-NISS) was used to monitor MDR-AB NI in intensive care units (ICUs) to prevent NI outbreaks. Therefore, the RT-NISS was used in the current study to monitor MDR-AB infections in a neurosurgery ICU. Clinical interventions, including recommended antibiotics, bacterial distribution in the patient analysis, and bed adjustments, were carried out based on the monitoring results. The RT-NISS was also used to monitor clinical data, implement, and provide training on NI control. The RT-NISS detected a potential cluster of XDR-AB when five patients admitted to the neurosurgery ICU were tested positive for AB between 11 and 17 June 2019. Only two infected cases originated in the hospital, and there was no NI outbreak. The hospital Infection Control Department took appropriate measures to prevent cross-infection; specifically, an epidemiologic investigation and environmental assessment were conducted, and NI prevention and outbreak management training was provided. In summary, the RT-NISS enhanced the timeliness and efficacy of NI control and surveillance in a neurosurgery ICU. In order to prevent NI outbreaks, the Real-Time Nosocomial Infection (NI) Surveillance System (RT-NISS) was employed to monitor MDR-AB NI in critical care units (ICU). Based on the monitoring data, clinical actions such as required antibiotics, bacterial distribution in the patient analysis, and bed changes were carried out. In a neurosurgery ICU, the RT-NISS improved the timeliness and efficacy of NI control and surveillance.
