ABSTRACT Hypoalbuminemia is associated with increased risk of infections. The aim of this study was to determine if serum albumin level is an independent predictor of nosocomial pneumonia in stroke patients. Data of 705 consecutive ischemic stroke patients admitted within 24 h after stroke onset were analyzed retrospectively. Serum albumin level was measured within 36 h after stroke onset. Nosocomial pneumonia was found in 10.5% of stroke patients. Patients with pneumonia had significantly lower serum albumin level than those without pneumonia (31.9 +/- 7.5 g/l vs. 35.5 +/- 6.9 g/l) and serum albumin level was associated with risk of pneumonia on multivariate analysis (OR: 0.95, 95% CI: 0.91-0.98). Our results show that serum albumin level is an independent predictor of nosocomial pneumonia in stroke patients.

    ABSTRACT: Hospital-acquired pneumonia (HAP) is one of the leading nosocomial infections and is associated with high morbidity and mortality. Numerous studies on HAP have been performed in intensive care units (ICUs), whereas very few have focused on patients in general wards. This study examined the incidence of, risk factors for, and outcomes of HAP outside the ICU. An incident case-control study was conducted in a 600-bed hospital between January 2006 and April 2008. Each case of HAP was randomly matched with 2 paired controls. Data on risk factors, patient characteristics, and outcomes were collected. The study group comprised 119 patients with HAP and 238 controls. The incidence of HAP outside the ICU was 2.45 cases per 1,000 discharges. Multivariate analysis identified malnutrition, chronic renal failure, anemia, depression of consciousness, Charlson comorbidity index ≥3, previous hospitalization, and thoracic surgery as significant risk factors for HAP. Complications occurred in 57.1% patients. The mortality attributed to HAP was 27.7%. HAP outside the ICU prevailed in patients with malnutrition, chronic renal failure, anemia, depression of consciousness, comorbidity, recent hospitalization, and thoracic surgery. HAP in general wards carries an elevated morbidity and mortality and is associated with increased length of hospital stay and increased rate of discharge to a skilled nursing facility.

    ABSTRACT: Our main objective was to assess incidence, risk factors, and outcomes of ventilator-associated pneumonia (VAP) in stroke patients. After obtaining approval from the Human Studies Committee, we reviewed the electronic records from our intensive care unit database of 111 stroke patients on mechanical ventilation for more than 48 hours. Thirty-six risk factors related to disease and general health status, and 8 related to care-all assigned a priori-were collected and analyzed. Selected factors with univariate statistical significance (P < .05) were then analyzed with multivariate logistic regression. Thirty-one patients developed pneumonia (28%). Methicillin-resistant Staphylococcus aureus (n = 12) and methicillin-sensitive S aureus (n = 7) were the most common pathogenic bacteria. Chronic lung disease, neurological status at admission as assessed by the National Institutes of Health Stroke Scale, and hemorrhagic transformation were the independent risk factors contributing to VAP. Worsening oxygenation index (arterial partial pressure of oxygen/fraction of inspired oxygen) and proton pump inhibitor use for ulcer prophylaxis were other potentially important factors. Pneumonia appears as a frequent problem in mechanically ventilated stroke patients. Chronic lung disease history, severity of stroke level at admission, and hemorrhagic transformation of stroke set the stage for developing VAP. The duration of both mechanical ventilation and intensive care unit stay gets significantly prolonged by VAP, but it does not affect mortality.

    ABSTRACT: stroke is the main cause of disability in high-income countries, and ranks second as a cause of death worldwide. Patients with acute stroke are at risk for infections, but reported post-stroke infection rates vary considerably. We performed a systematic review and meta-analysis to estimate the pooled post-stroke infection rate and its effect on outcome. MEDLINE and EMBASE were searched for studies on post-stroke infection. Cohort studies and randomized clinical trials were included when post-stroke infection rate was reported. Rates of infection were pooled after assessment of heterogeneity. Associations between population- and study characteristics and infection rates were quantified. Finally, we reviewed the association between infection and outcome. 87 studies were included involving 137817 patients. 8 studies were restricted to patients admitted on the intensive care unit (ICU). There was significant heterogeneity between studies (P < 0.001, I(2) = 97%). The overall pooled infection rate was 30% (24-36%); rates of pneumonia and urinary tract infection were 10% (95% confidence interval [CI] 9-10%) and 10% (95%CI 9-12%). For ICU studies, these rates were substantially higher with 45% (95% CI 38-52%), 28% (95%CI 18-38%) and 20% (95%CI 0-40%). Rates of pneumonia were higher in studies that specifically evaluated infections and in consecutive studies. Studies including older patients or more females reported higher rates of urinary tract infection. Pneumonia was significantly associated with death (odds ratio 3.62 (95%CI 2.80-4.68). Infection complicated acute stroke in 30% of patients. Rates of pneumonia and urinary tract infection after stroke were 10%. Pneumonia was associated with death. Our study stresses the need to prevent infections in patients with stroke.
