NRS 2002 as a Predictor of Prognosis in COPD With Respiratory Failure

West China Hospital520 enrolled

Overview

This is a prospective study of patients diagnosed with chronic obstructive pulmonary disease (COPD) with respiratory failure and admitted in West China Hospital during April 2017 to March 2019. The following variables will be prospectively studied: age, sex, height, weight, respiratory function indicators, arterial blood gas analysis results, biochemical data, nutritional risk screening 2002 (NRS 2002) score, short-term and long-term prognostic outcomes. The purpose of this study is to assess whether NRS 2002 is a useful prognosis predictor in COPD patients with respiratory failure.
