A prolonged intensive care unit stay defines a worse long-term prognosis - Insights from the critically ill mortality by age (Cimba) study.

BACKGROUND: Patients with critical illness often survive the intensive care unit (ICU) at a cost of prolonged length of stay (LOS) and slow recovery. This chronic critically ill disease may lead to long-term poor outcomes, especially in older or frail patients. OBJECTIVES: The main goal of this study was to address the characteristics and outcomes of patients with prolonged ICU LOS. Mainly, short- and long-term admissions were compared to identify risk factors for persistent critical illness and to characterise the impact on ICU, hospital, and long-term mortality. METHODS: Subanalysis of a retrospective, multicentric, observational study addressing the 2-year outcome of patients admitted to Portuguese ICUs (the Cimba study). Patients were segregated according to an ICU LOS of ≥14 days. RESULTS: Data from 37 118 patients were analysed, featuring a median ICU LOS of 4 days (percentile: 25-75 2-9), and a mortality of 16.1% in the ICU, 24.0% in the hospital, and 38.7% after 2 years. A total of 5334 patients (14.4%) had an ICU LOS of ≥14 days (corresponding to 48.9% of all ICU patients/days). Patients with prolonged LOS were more often younger (52.8% vs 46.4%, were ≤65 years of age , p < 0.001), although more severe (Simplified Acute Physiology Score II: 49.1 ± 16.9 vs 41.8 ± 19.5, p < 0.001), and had higher ICU and hospital mortality (18.3% vs 15.7%, and 31.2 vs 22.8%, respectively). Prolonged ICU LOS was linked to an increased risk of dying during the 2-year follow-up (adjusted Cox proportional hazard: 1.65, p < 0.001). CONCLUSION: Prolonged LOS is associated with a long-term impact on patient prognosis. More careful planning of care should incorporate these data.

Streptococcus oralis Meningitis.

Streptococcus oralis is part of the normal flora of the oropharyngeal, nasal, gastrointestinal and genitourinary tracts. Classically, it shows low pathogenicity and virulence, but can very rarely cause meningitis in patients who have undergone dental procedures and have poor oral hygiene. The purpose of this report is to highlight the importance of considering S. oralis as a cause of meningitis in patients with poor oral hygiene. A 53-year-old man was admitted to the emergency department with high fever (39.4°C), headache and drowsiness. His mouth was unhygienic. He was diagnosed with meningitis and empiric antibiotics (ceftriaxone plus ampicillin) and dexamethasone were started. S. oralis was isolated from cerebrospinal fluid. Ampicillin and dexamethasone were stopped, while ceftriaxone was continued with full recovery of the patient. LEARNING POINTS: Viridans streptococci such as Streptococcus oralis can rarely cause meningitis as well as endocarditis in patients with poor dental hygiene.Streptococcus viridans meningitis responds well to empiric antibiotic therapy.Patients with any form of streptococcus viridans infection should be screened for endocarditis.

Intra-Vesical Colistin for Pseudomonas aeruginosa Urinary Tract Infections.

The numbers of multiple drug-resistant Gram-negative bacterial infections are rising worldwide. The threat is increased by the lack of new antibiotics, so clinicians are turning to older drugs previously abandoned due to their recognized toxicity, such as colistin. However, the need to avoid kidney toxicity from colistin has led to its topical use. We present the case of a patient with type I cardiorenal syndrome with cystitis due to multiple drug-resistant Pseudomonas aeruginosa who was successfully treated with intravesical instillation of colistin. LEARNING POINTS: The case report is one of the few in the literature on the intravesical instillation of colistin to address lower urinary tract infection.Isolated intravesical colistin instillation was effective in a patient with anuria.
