Adult pneumonia in a general hospital. Etiology and host risk factors
Abstract
Adult patients admitted to the medical service of a city-county hospital for treatment of presumptive acute pneumonia were followed up in a prospective study of pneumonia etiology from July 1, 1967, to June 30, 1968. Laboratory specimens were tested for bacterial, mycoplasmal, and viral agents, and results, supported by serologic data, were evaluated. Of 292 cases of pneumonia, 167 (57%) could be attributed to specific bacterial pathogens. The pneumococcus was the most frequent etiologic agent (62%), gram-negative bacilli the second most frequent (20%), andStaphylococcus aureusthe third (10%). Viral infections other than influenza appeared to be unrelated to adult pneumonias. Four fifths of the patients had one or more associated diseases. Overall mortality was 24%. An age of 40 years and over and gram-negative bacillus or staphylococcal etiology were identified as mortality risk factors.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
