COPD review finds a gap in combined heart and lung risk prediction
Existing models addressed separate outcomes, but none covered the combined cardiovascular and COPD flare-up outcome sought by the review.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The researchers found no community-based model for predicting the combined outcome of major cardiovascular events and acute COPD flare-ups. Some models predicted death from any cause, but none had their clinical usefulness evaluated. This is evidence of a prediction research gap, rather than evidence that using a risk score improves care.
The abstract reports high risk of bias in many studies. This abstract-based account also lacks the prediction time horizons and information needed to assess whether these models would help in a particular clinical setting.
What researchers assessed
Researchers examined models designed to predict cardiovascular events, COPD flare-ups or death using community-based data. The abstract reports pooled performance for death prediction only; cardiovascular-event and flare-up models were not eligible for pooling.
Prediction and practical benefit
A model's ability to distinguish higher-risk from lower-risk patients is different from showing that it helps patients. The review found no evaluations of clinical usefulness, leaving that practical question unanswered.
