Discharge of dependent patients directly from the intensive care units after a critical illness: a single-center retrospective cohort study

OBJECTIVE

This study aimed to determine the mortality and predictive factors affecting mortality of patients discharged directly from the intensive care unit (ICU) at the third- and sixth-month post-discharge. Additionally, it assessed the rate of hospital readmissions within 30 days post-discharge and the satisfaction level of family members with post-ICU care.

PATIENTS AND METHODS

In this single-center, retrospective, observational cohort study, dependent patients discharged directly from the ICU between July 1, 2019, and July 1, 2022, were included. Data on patients' demographics, reasons for admission, pre-existing diseases, length of ICU stay, advanced clinical interventions, discharge destination, physiological status on discharge, readmission within 30 days, and clinical outcomes and mortality at the third- and sixth-months post-discharge were collected.

RESULTS

The study included 240 patients, representing 45.8% of all patients discharged directly from the ICU. Of these, 122 were discharged to their homes, and 118 to intermediate care units intermediate care units (IMCUs). The mean age was 71 years [interquartile range (IQR): 22.8]. Among the patients, 113 (47.1%) were readmitted within 30 days post-discharge, and 23 (20.35%) were re-hospitalized. The overall mortality rate in the third and sixth months was 25.4% and 32.5%, respectively. Logistic regression identified age, readmission within 30 days, and Glasgow Outcome Scale-Extended (GOS-E) at discharge as predictive factors for short-term and long-term mortality. Patients discharged to IMCUs had significantly higher long-term mortality. Family members of patients discharged to their homes had significantly higher satisfaction with post-ICU care (p=0.002).

CONCLUSIONS

Discharging patients directly from the ICU to their homes may yield better outcomes in selected patients compared to discharging to IMCUs. This approach may also enable more efficient use of hospital resources and reduce ICU occupancy and associated costs.

Epidemiology and risk factors of 28-day mortality of hospital-acquired bloodstream infection in Turkish intensive care units: a prospective observational cohort study

OBJECTIVES

To uncover clinical epidemiology, microbiological characteristics and outcome determinants of hospital-acquired bloodstream infections (HA-BSIs) in Turkish ICU patients.

METHODS

The EUROBACT II was a prospective observational multicontinental cohort study. We performed a subanalysis of patients from 24 Turkish ICUs included in this study. Risk factors for mortality were identified using multivariable Cox frailty models.

RESULTS

Of 547 patients, 58.7% were male with a median [IQR] age of 68 [55-78]. Most frequent sources of HA-BSIs were intravascular catheter [182, (33.3%)] and lower respiratory tract [175, (32.0%)]. Among isolated pathogens (n = 599), 67.1% were Gram-negative, 21.5% Gram-positive and 11.2% due to fungi. Carbapenem resistance was present in 90.4% of Acinetobacter spp., 53.1% of Klebsiella spp. and 48.8% of Pseudomonas spp. In monobacterial Gram-negative HA-BSIs (n = 329), SOFA score (aHR 1.20, 95% CI 1.14-1.27), carbapenem resistance (aHR 2.46, 95% CI 1.58-3.84), previous myocardial infarction (aHR 1.86, 95% CI 1.12-3.08), COVID-19 admission diagnosis (aHR 2.95, 95% CI 1.25-6.95) and not achieving source control (aHR 2.02, 95% CI 1.15-3.54) were associated with mortality. However, availability of clinical pharmacists (aHR 0.23, 95% CI 0.06-0.90) and source control (aHR 0.46, 95% CI 0.28-0.77) were associated with survival. In monobacterial Gram-positive HA-BSIs (n = 93), SOFA score (aHR 1.29, 95% CI 1.17-1.43) and age (aHR 1.05, 95% CI 1.03-1.08) were associated with mortality, whereas source control (aHR 0.41, 95% CI 0.20-0.87) was associated with survival.

CONCLUSIONS

Considering high antimicrobial resistance rate, importance of source control and availability of clinical pharmacists, a multifaceted management programme should be adopted in Turkish ICUs.

Epidemiology and outcomes of hospital-acquired bloodstream infections in intensive care unit patients: the EUROBACT-2 international cohort study

PURPOSE

In the critically ill, hospital-acquired bloodstream infections (HA-BSI) are associated with significant mortality. Granular data are required for optimizing management, and developing guidelines and clinical trials.

METHODS

We carried out a prospective international cohort study of adult patients (≥ 18 years of age) with HA-BSI treated in intensive care units (ICUs) between June 2019 and February 2021.

RESULTS

2600 patients from 333 ICUs in 52 countries were included. 78% HA-BSI were ICU-acquired. Median Sequential Organ Failure Assessment (SOFA) score was 8 [IQR 5; 11] at HA-BSI diagnosis. Most frequent sources of infection included pneumonia (26.7%) and intravascular catheters (26.4%). Most frequent pathogens were Gram-negative bacteria (59.0%), predominantly Klebsiella spp. (27.9%), Acinetobacter spp. (20.3%), Escherichia coli (15.8%), and Pseudomonas spp. (14.3%). Carbapenem resistance was present in 37.8%, 84.6%, 7.4%, and 33.2%, respectively. Difficult-to-treat resistance (DTR) was present in 23.5% and pan-drug resistance in 1.5%. Antimicrobial therapy was deemed adequate within 24 h for 51.5%. Antimicrobial resistance was associated with longer delays to adequate antimicrobial therapy. Source control was needed in 52.5% but not achieved in 18.2%. Mortality was 37.1%, and only 16.1% had been discharged alive from hospital by day-28.

CONCLUSIONS

HA-BSI was frequently caused by Gram-negative, carbapenem-resistant and DTR pathogens. Antimicrobial resistance led to delays in adequate antimicrobial therapy. Mortality was high, and at day-28 only a minority of the patients were discharged alive from the hospital. Prevention of antimicrobial resistance and focusing on adequate antimicrobial therapy and source control are important to optimize patient management and outcomes.

Clinical Outcomes and Independent Risk Factors for 90-Day Mortality in Critically Ill Patients with Respiratory Failure Infected with SARS-CoV-2: A Multicenter Study in Turkish Intensive Care Units

Background:

There are limited data on the long-term outcomes of COVID-19 from different parts of the world.

Aims:

To determine risk factors of 90-day mortality in critically ill patients in Turkish intensive care units (ICUs), with respiratory failure.

Study design:

Retrospective, observational cohort.

Methods:

Patients with laboratory-confirmed COVID-19 and who had been followed up in the ICUs with respiratory failure for more than 24 hours were included in the study. Their demographics, clinical characteristics, laboratory variables, treatment protocols, and survival data were recorded.

Results:

A total of 421 patients were included. The median age was 67 (IQR: 57-76) years, and 251 patients (59.6%) were men. The 90-day mortality rate was 55.1%. The factors independently associated with 90-day mortality were invasive mechanical ventilation (IMV) (HR 4.09 [95% CI: [2.20-7.63], P < .001), lactate level >2 mmol/L (2.78 [1.93-4.01], P < .001), age ≥60 years (2.45 [1.48-4.06)], P < .001), cardiac arrhythmia during ICU stay (2.01 [1.27-3.20], P = .003), vasopressor treatment (1.94 [1.32-2.84], P = .001), positive fluid balance of ≥600 mL/day (1.68 [1.21-2.34], P = .002), PaO₂/FiO₂ ratio of ≤150 mmHg (1.66 [1.18-2.32], P = .003), and ECOG score ≥1 (1.42 [1.00-2.02], P = .050).

Conclusion:

Long-term mortality was high in critically ill patients with COVID-19 hospitalized in intensive care units in Turkey. Invasive mechanical ventilation, lactate level, age, cardiac arrhythmia, vasopressor therapy, positive fluid balance, severe hypoxemia and ECOG score were the independent risk factors for 90-day mortality.

International Nosocomial Infection Control Consortium (INICC) report, data summary of 45 countries for 2012-2017: Device-associated module

BACKGROUND

We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific.

METHODS

During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied.

RESULTS

Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher.

CONCLUSIONS

Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

Erectile dysfunction in patients with psoriasis: potential impact of the metabolic syndrome

BACKGROUND

Psoriasis is a chronic inflammatory skin disease that affects up to 5.5% of world population and is associated with erectile dysfunction (ED). Aim of the present study was to investigate impact of metabolic syndrome (MetS) on association between psoriasis and ED as well as to improve our understanding of this association via studying other possible causes of ED such as psychological factors and disease effects.

PATIENTS AND METHODS

The patient group included 37 male psoriasis patients and control group 28 healthy men. Severity of psoriasis was determined using Psoriasis Area and Severity Index (PASI), and ED was evaluated using International Index of Erectile Function (IIEF) Scale. Psychiatric state of the patients were determined using Beck Depression Inventory (BDI). MetS was diagnosed using the National Cholesterol Education Program Adult Treatment Panel III criteria.

RESULTS

MetS, ED prevalence and BDI score were significantly higher in psoriasis patient group (p = 0.032, p = 0.018 and p < 0.001). Average IIEF score of psoriasis patients with and without MetS, on the other hand, was not different (p = 0.073). IIEF score had negative correlations with age, BDI and PASI scores. In multiple linear regression analysis, BDI score, old age and smoking (but not MetS) were found to be independent predictors of ED.

CONCLUSIONS

ED, MetS and depression frequencies were significantly higher in psoriasis patient group. In addition, psoriasis severity and ED parameters were closely associated. Depression, old age and smoking were found to be independent risk factors for ED.
