About this study
Official title: Prediction of Prognosis in Patients With Chronic Obstructive Pulmonary Disease With Respiratory Failure: A Comparison of Three Nutritional Assessment Methods
This is a retrospective study of patients diagnosed with chronic obstructive pulmonary disease (COPD) with respiratory failure and admitted in West China Hospital during January 2014 to March 2016 by review of medical records. The following variables will be retrospectively studied: age, sex, marriage, height, weight, respiratory rate, PaO2, PaCO2, nutritional risk screening 2002 (NRS 2002) score, ALB, short-term and long-term prognostic outcomes, and so on. The purpose of this study is to compare the predictive power of three widely used nutritional assessment methods (BMI, NRS 2002 and ALB) predicting the prognostic outcomes in a cohort of COPD patients with respiratory failure.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Predictive value of nutritional assessment methods in identifying COPD patients with respiratory failure who will have poor prognosis, in terms of in-hospital death (time frame: up to 27 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
