In elderly patients with infection, the initial CRP value alone does not have prognostic value, but changes observed in serial CRP measurement are a valid indicator of prognosis.

Independent of all other factors, delirium is associated with higher mortality risk.

BackgroundPercutaneous endoscopic gastrotomy (PEG) enables long-term enteral feeding. The aim of this study was to identify biomarkers that may guide the decision of whether to perform the elective procedure of PEG.MethodsThe medical records of all patients who underwent PEG in our hospital from 2010 to 2016 were screened retrospectively. Patients with mortality within a 30-day follow-up period and those without were compared using the Chi-square test, and continuous variables were compared with the Kruskal-Wallis and Mann-Whitney U tests. Receiver operating characteristic (ROC) curve analysis was used to demonstrate the ability of biomarkers to predict mortality; a cut-off point was determined and its sensitivity, specificity, and positive and negative predictive values were calculated. The Youden index was used to determine the cut-off point. Kaplan-Meier analysis was used to identify PEG-related mortality risk factors and a Cox regression model was applied for risk characterization.ResultsA total of 120 patients who underwent PEG were evaluated in the study. The mean age was 67.00 ± 18.00 years. The most common indication for PEG was cerebrovascular disease, in 69 (57.5%) of the patients. Infection of the PEG site was most common within 14 days after PEG tube placement, occurring in 13 patients (10.3%). The mortality rate among patients with post-PEG infection was 68.2%, significantly higher than in patients without infection (P = 0.012). Thirty-four patients (28.3%) died within 30 days of undergoing PEG. CRP values ≥ 78.31 mg/L increased mortality by 8.756-fold, and albumin levels < 2.71 g/dL increased mortality by 2.255-fold.ConclusionOur results indicate that the presence of both high CRP level and low albumin level were associated with significantly higher rate of mortality (73.1%) in patients who underwent PEG.
