Physical oral care prevents ventilator-associated pneumonia in Vietnam: A prospective interventional study.

BACKGROUND: Ventilator-associated pneumonia (VAP) has emerged as a critical issue in the intensive care unit (ICU) because of its high burden on patients and medical staff. Here, we examined the potential for reducing VAP incidence through physical oral care interventions without any medication. METHODS: This prospective interventional study compared VAP incidence during an 8-month baseline period (usual oral care) and a 9-month intervention period (physical oral care with sponge brush) among patients who received mechanical ventilation for >48 h in a tertiary care hospital in Vietnam from 2017 to 2019. Physical oral care was provided by general ICU nurses who had been trained by dentists and infection control nurses. VAP was diagnosed using the Clinical Pulmonary Infection Score. RESULTS: In total, 423 patients were enrolled in the baseline group and 454 patients were enrolled in the intervention group; 303 and 300 patients, respectively, were included in the analysis. Two hundred thirty-eight VAP episodes were identified: 135 (44.6%) during the baseline period and 103 (34.3%) during the intervention period. Univariate analysis revealed significant reduction of VAP occurrence in the intervention period (odds ratio = 0.65; 95% confidence interval = 0.47-0.90; P = 0.010). The incidences of VAP per 1000 ventilator-days were 63.4 (135/2128) during the baseline period and 48.4 (103/2128) during the intervention period (P = 0.038). CONCLUSIONS: Physical oral care without any medication (e.g., chlorhexidine) reduced VAP incidence in the ICU. This method could be used to reduce VAP incidence, particularly in countries with limited medical resources.

Efficacy of a New Post-Mouthwash Intervention (Wiping Plus Oral Nutritional Supplements) for Preventing Aspiration Pneumonia in Elderly People: A Multicenter, Randomized, Comparative Trial.

BACKGROUND/AIMS: Aspiration pneumonia is a common cause of death among the elderly (≥90-year-old) in nursing homes. Studies suggest that its incidence could be reduced by oral care interventions. We aimed to evaluate the efficacy of a new oral care intervention: wiping plus oral nutritional supplements (ONS). METHODS: This prospective observational study was conducted in 252 patients (age 88.0 ± 6.5 years) in 75 nursing homes, rehabilitation hospitals, and other care facilities. Patients were randomly divided into an intervention group (n = 74) and a control group (n = 107), whose members received conventional oral care. Body mass index, activities of daily living (Barthel index), and complete blood count and biochemistry parameters were measured at 2, 4, 6, and 8 months. RESULTS: The cumulative incidence of pneumonia at 8 months tended to be lower in the intervention than in the control group (7.8 vs. 17.7%, p = 0.056) and was significantly lower for men in the intervention group (p = 0.046). CONCLUSIONS: Our new intervention "wiping plus providing ONS" method appears to help prevent aspiration pneumonia, thereby reducing mortality risk. In this study, we disseminate information on how this method is used in Japan.

Interleukin-8 and clinical symptoms can be prognostic indicators for advanced cancer patients with cachexia.

OBJECTIVES: Prognostic prediction is a significant tool for selecting appropriate treatment in advanced cancer patients with cachexia, at a time when it is important to offer high-quality palliative care and improve quality of life until death. In this retrospective study, we investigated the prognostic potential of serum cytokine level and various clinical symptoms by analyzing the pathological conditions and metabolic dynamics of cachexia in advanced cancer patients. METHODS: One hundred and fifty-three advanced cancer patients who underwent palliative care and died at the Department of Surgery and Palliative Medicine, Fujita Health University Nanakuri Memorial Hospital between 1 January 2004 and 30 June 2007 were eligible for the study. We simultaneously assessed their blood factors and clinical symptoms at admission. All patients were divided into two groups according to median survival time to analyze the risk factors for prognosis. RESULTS: Multivariate analysis revealed the following independent prognostic factors: interleukin (IL)-8 (odds ratio [OR]=4.17, 95% confidence interval [CI]=1.52-11.41, p=0.002), general fatigue (OR=1.22, 95%CI=1.03-1.45, p=0.019), anorexia (OR=1.19, 95%CI=1.04-1.37, p=0.008), dyspnea (OR=1.19, 95%CI=1.02-1.38, p=0.024), depression (OR=1.28, 95%CI=1.11-1.47, p<0.001), nausea (OR=1.25, 95%CI=1.05-1.48, p=0.007), dry mouth (OR=1.19, 95%CI=1.01-1.40, p=0.032), and overall assessment score (OR=1.05, 95%CI=1.02-1.09, p<0.001). Patients with low IL-8 (<1.347 pg/ml) and low overall assessment score (<26) had significantly better prognosis (both p<0.0001). CONCLUSIONS: High IL-8 level and clinical symptoms can be prognostic indicators for advanced cancer patients with cachexia.
