RT Journal Article SR Electronic T1 Deaths in risk classes I–III: a measure of quality of care in patients hospitalised with CAP? JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP 103 OP 105 DO 10.1183/09031936.03.00072803 VO 23 IS 1 A1 T.J. Marrie YR 2004 UL http://erj.ersjournals.com/content/23/1/103.abstract AB All deaths occurring in patients with community-acquired pneumonia in risk classes I–III were reviewed as a quality-of-care measure. The immediate and underlying causes of death were classified according to the World Health Organization protocol. Eleven (1.8%) of the 608 low-risk patients died. Three of the patients did not have pneumonia, one of whom was admitted with atypical pulmonary oedema due to stenosis of a prosthetic heart valve. Failure to include chronic lung disease in the severity-of-illness scoring system resulted in misclassification of seven patients. The most common underlying causes of death were pulmonary fibrosis at 27%, chronic obstructive lung disease at 18% and cancer at 27%. Respiratory failure was the immediate cause of death in 64% of patients, cardiac causes in 27%, and pneumonia in 9%. To conclude, the review of deaths in patients at low risk for mortality is useful for monitoring the quality of care received by patients who require admission for the treatment of community-acquired pneumonia, and that the pneumonia-specific severity-of-illness scoring system results in misclassification of patients with chronic obstructive lung disease and pulmonary fibrosis.
