Abstract
in English, French

Objective: To determine factors associated with the length of stay (LOS) for patients with suspected community-acquired pneumonia (CAP) who required hospitalization for treatment.

Study design: The authors studied a population-based prospective cohort of 2,757 adults with suspected CAP who were admitted over a two-year period. Logistic regression, multiple linear regression, and classification and regression trees were used to determine the factors associated with LOS.

Setting: The study was conducted in two community and tertiary care hospitals, two community and secondary care hospitals, and two community hospitals in the Capital Health Region of Edmonton, Alberta.

Results: Symptoms such as sweats, shaking chills and wheezing were associated with an LOS of seven days or shorter, whereas weight loss, functional impairment, heart, renal or neoplastic diseases and time to first dose of antibiotic were predictive of an LOS greater than seven days. Regression tree analysis indicated that rapid achievement of physiological stability was associated with a shorter LOS. The use of an indwelling urinary catheter was found to be an important determinant of LOS.

Conclusions: The present study found several new associations with increased LOS in patients with CAP, including functional status, time to receipt of first dose of antibiotic therapy, use of certain antibiotics, presence of a urinary catheter and the importance of time to physiological stability. An intervention targeting avoidance of urinary catheters may be associated with a shorter LOS.

OBJECTIF :: Déterminer les facteurs associés à la durée d’hospitalisation (DH) des patients atteints d’une pneumonie d’origine extra-hospitalière (POEH) présumée devant être hospitalisés pour être traités.

CONCEPTION DE L’ÉTUDE :: Les auteurs ont étudié une cohorte prospective en population de 2 757 adultes atteints d’une POEH présumée, hospitalisés au cours d’une période de deux ans. La régression logistique, la régression linéaire multiple et les arbres de classification et de régression ont permis de déterminer les facteurs associés à la DH.

LIEU :: L’étude a été menée dans deux hôpitaux généraux et tertiaires, deux hôpitaux généraux et secondaires et deux hôpitaux généraux de la région de la capitale d’Edmonton, en Alberta.

RÉSULTATS :: Des symptômes comme la transpiration, les frissons et le wheezing s’associaient à une DH de sept jours ou moins, tandis que la perte de poids, l’atteinte fonctionnelle, une maladie cardiaque, rénale ou néoplastique et le délai avant la première dose d’antibiotiques étaient prédictifs d’une DH de plus de sept jours. D’après l’analyse des arbres de régression, l’obtention rapide d’une stabilité physiologique favorisait une réduction de la DH. Le recours à une sonde urinaire à demeure constituait un important déterminant de la DH.

CONCLUSIONS :: La présente étude a permis d’observer plusieurs nouvelles associations à une augmentation de la DH chez les patients atteints d’une POEH, y compris l’état fonctionnel, le délai avant la première dose de l’antibiothérapie, l’utilisation de certains antibiotiques, la présence d’un cathéter urinaire et l’importance du délai avant la stabilité physiologique. Une intervention visant à éviter les cathéters urinaires pourrait favoriser une réduction de la DH.
