dc.description.abstractObjectiveTo assess the effects of a cardiopulmonary ultrasound (CPUS) examination on diagnostic accuracy for critically ill patients in a resourceâ limited setting.MethodsApproximately half of the emergency medicine resident physicians at the Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana, were trained in a CPUS protocol. Adult patients triaged to the resuscitation area of the emergency department (ED) were enrolled if they exhibited signs or symptoms of shock or respiratory distress. Patients were assigned to the intervention group if their treating physician had completed the CPUS training. The physician’s initial diagnostic impression was recorded immediately after the history and physical examination in the control group, and after an added CPUS examination in the intervention group. This was compared to a standardised final diagnosis derived from post hoc chart review of the patient’s care at 24 h by two blinded, independent reviewers using a clearly defined and systematic process. Secondary outcomes were 24â h mortality and use of IV fluids, diuretics, vasopressors and bronchodilators.ResultsOf 890 patients presenting during the study period, 502 were assessed for eligibility, and 180 patients were enrolled. Diagnostic accuracy was higher for patients who received the CPUS examination (71.9% vs. 57.1%, Î 14.8% [CI 0.5%, 28.4%]). This effect was particularly pronounced for patients with a â cardiacâ diagnosis, such as cardiogenic shock, congestive heart failure or acute valvular disease (94.7% vs. 40.0%, Î 54.7% [CI 8.9%, 86.4%]). Secondary outcomes were not different between groups.ConclusionsIn an urban ED in Ghana, a CPUS examination improved the accuracy of the treating physician’s initial diagnostic impression. There were no differences in 24â h mortality and a number of patient care interventions.ObjectifEvaluer les effets de l’examen échographique cardioâ pulmonaire (CPUS) sur la précision du diagnostic chez les patients gravement malades dans un cadre à ressource limitée.MéthodesEnviron la moitié des médecins résidents en médecine d’urgence à la Komfo Anokye Teaching Hôpital (KATH) à Kumasi, au Ghana ont été formés pour un protocole de CPUS. Les patients adultes triés dans l’unité de ressuscitation des soins intensifs ont été inscrits s’ils présentaient des signes ou des symptômes de choc ou d’une détresse respiratoire. Les patients ont été assignés au groupe d’intervention si leur médecin traitant avait suivi la formation CPUS. Le diagnostic initial du médecin a été enregistré immédiatement après l’anamnèse et l’examen physique dans le groupe témoin, et après un examen CPUS ultérieur dans le groupe d’intervention. Cela a été comparé à un diagnostic final standard dérivé de l’analyse postâ hoc en aveugle des dossiers de soins du patient à 24 heures par deux examinateurs indépendants, au moyen d’un processus clairement défini et systématique. Les résultats secondaires étaient la mortalité de 24 heures et l’utilisation de fluides en IV, de diurétiques, de vasopresseurs et de bronchodilatateurs.RésultatsSur 890 patients présentés au cours de la période dâ étude, 502 ont été évalués pour lâ éligibilité et 180 patients ont été inscrits. La précision du diagnostic était plus élevée chez les patients ayant reçu l’examen CPUS (71,9% contre 57,1%, Î 14,8% [IC: 0,5% à 28.4%]). Cet effet était particulièrement marquée pour les patients avec un diagnostic «cardiaque», tel que le choc cardiogénique, l’insuffisance cardiaque congestive ou une maladie aiguë valvulaire (94,7% contre 40,0%, Î 54,7% [IC: 8,9% à 86,4%]). Les résultats secondaires nâ étaient pas différents entre les groupes.ConclusionsDans un service de soins intensifs urbain au Ghana, un examen CPUS améliorait la précision du diagnostic initial du médecin traitant. Il n’y avait aucune différence dans la mortalité de 24 heures et dans le nombre des interventions de soins.
