Objective:

Patients in the emergency department (ED) who have been admitted to hospital (inpatient “boarders”) are associated with ED overcrowding. They are also a symptom of a hospital-wide imbalance between demand and supply of resources. We analyzed the trends of inpatient admissions, ED boarding volumes, lengths of stay and bed resources of 3 major admitting services at our teaching institution.

Methods:

We used hospital databases from Jan. 1, 2004, to Dec. 31, 2007, to analyze ED visits that resulted in admission to hospital.

Results:

During the study period, 21 986 ED patients were admitted to hospital. The percentage of cancer-related admissions to the oncology admitting service decreased from 48% in 2004 to 24% in 2007, and admissions to general internal medicine (GIM) increased nearly 2-fold, from 28% in 2004 to 54% in 2007. In addition, GIM admitted about 10% more myocardial infarction and heart failure patients than did cardiology. General internal medicine constituted the majority of ED boarders and had a median boarding length of stay of approximately 15 hours. Inpatient beds on oncology and cardiology services remained static.

Conclusion:

Without bed capacity to admit more patients, our specialty services relied on GIM to serve as a safety net. At the same time, GIM was cited as a main source of ED congestion as their patients occupied more ED beds for longer periods than any other admitting service. The data presented in this study has helped effect positive change within our institution. Other hospitals running at or near capacity and faced with similar ED congestion may apply the methods we used in this study to analyze the cause and nature of their situation.

Résumé

RÉSUMÉObjectif:

On associe les patients ayant été admis à l'hôpital après une consultation à l'urgence (« pensionnaires ») à l'engorgement des urgences. Ils sont également un symptôme d'un déséquilibre important entre l'offre et la demande des ressources dans tout l'hôpital. Nous avons analysé les tendances relativement aux admissions, aux volumes de « pensionnaires » (patients admis occupant une civière à l'urgence), aux durées de séjour et au nombre de lits de 3 grands départements d'hospitalisation à notre établissement hospitalier universitaire.

Méthodes:

Nous avons utilisé les données de l'hôpital, entre le 1er janvier 2004 et le 31 décembre 2007, pour analyser les visites à l'urgence qui ont mené à l'admission à l'hôpital.

Résultats:

Au cours de la période de l'étude, 21 986 patients à l'urgence ont été admis à l'hôpital. Le pourcentage d'hospitalisations liées au cancer au département d'oncologie a diminué entre 2004 et 2007, passant de 48 % à 24 %, et les hospitalisations en médecine interne générale (MIG) ont presque doublé, passant de 28 % en 2004 à 54 % en 2007. En outre, le service de MIG a admis environ 10 % de plus de cas d'infarctus du myocarde et d'insuffisance cardiaque que la cardiologie. La médecine interne générale représentait la majorité des « pensionnaires », qui occupaient une civière à l'urgence pendant une durée médiane d'environ 15 heures. Le nombre de lits en oncologie et en cardiologie est demeuré stable.

Conclusion:

Sans la capacité en lits pour admettre plus de patients, nos départements spécialisés considéraient la MIG comme un filet de sécurité. Parallèlement, la GIM était citée comme une des principales sources de congestion dans les urgences, ses patients occupant plus de lits et plus longtemps que tout autre département d'hospitalisation. Les données présentées dans cette étude ont permis d'apporter des changements positifs au sein de notre établissement. D'autres hôpitaux qui fonctionnent à pleine capacité ou presque et dont les services d'urgence font face à une congestion similaire peuvent appliquer les méthodes que nous avons utilisées dans cette étude pour analyser leur situation et en déterminer la cause.
