The "Just Right" Amount of Oxygen. Improving Oxygen Use in a Rwandan Emergency Department.

Rationale: Despite oxygen's classification as an essential medication by the World Health Organization, it is inconsistently available in many resource-constrained settings. Hypoxemia is associated with increased mortality, and mounting evidence suggests that hyperoxia may also be associated with adverse outcomes.Objectives: To determine if overuse of oxygen for some patients in a Rwandan tertiary care hospital emergency department might coexist with oxygen shortages and underuse of oxygen for other patients, and whether an educational intervention coupled with provision of pulse oximeters could improve the distribution of limited oxygen resources.Methods: We screened all patients in the adult emergency department (ED) of the University Teaching Hospital of Kigali for hypoxemia and receipt of oxygen therapy for 5 weeks. After completing baseline data collection, we provided pulse oximeters and conducted a didactic training with pre- and posttests on oxygen titration, with a chosen target oxygen saturation (SpO2) of 90% to 95%. Four and 12 weeks after the intervention, we evaluated all patients in the ED again for SpO2 and receipt of oxygen therapy for 4 weeks each period. We also recorded ED oxygen use and availability of reserve oxygen for the hospital during the three study periods.Results: During all data collection periods, 214 of 1,765 (12.1%) unique patients screened were hypoxemic. The proportion of patient-days with appropriately titrated oxygen therapy (SpO2, 90-95%) increased from 18.7% at baseline to 38.5% and 42.0% at 4 and 12 weeks postintervention (P < 0.001). On a multiple-choice examination testing knowledge of appropriate oxygen titration, clinicians' scores improved from average 60% (interquartile range [IQR], 40-80%) correct to 80% (IQR, 60-80%) correct immediately after the educational intervention (P < 0.001). Oxygen use in the ED decreased from a median of 32.0 (IQR, 28.0-35.0) tanks per day to 25.5 (IQR, 24.0-29.0) and 16.0 (IQR, 12.5-21.0) tanks per day at Weeks 4 and 12, respectively (P < 0.001), and the median daily number of tanks in reserve for the hospital appeared to increase, although this did not reach statistical significance (30.0 [IQR, 9.0-46.0], 86.5 [IQR, 74.0-92.0], and 75.5 [IQR, 8.5-88.5], respectively; P = 0.07).Conclusions: Among patients in a Rwandan adult ED, 12.1% of patients were hypoxemic and 81.3% of patient-days were either under- or overtreated with oxygen during baseline data collection on the basis of our defined target of SpO2 90% to 95%. Follow-up results at 4 and 12 weeks postintervention demonstrated sustained improvement in oxygen titration and likely increased availability of oxygen resources.

Development of a trauma and emergency database in Kigali, Rwanda.

INTRODUCTION: Injuries account for 10% of the global burden of disease, resulting in approximately 5.8 million deaths annually. Trauma registries are an important tool in the development of a trauma system; however, limited resources in low- and middle-income countries (LMIC) make the development of high-quality trauma registries challenging. We describe the development of a LMIC trauma registry based on a robust retrospective chart review, which included data derived from prehospital, emergency centre and inpatient records. METHODS: This paper outlines our methods for identifying and locating patients and their medical records using pragmatic and locally appropriate record linkage techniques. A prehospital database was queried to identify patients transported to University Teaching Hospital - Kigali, Rwanda from December 2012 through February 2015. Demographic information was recorded and used to create a five-factor identification index, which was then used to search OpenClinic GA, an online open source hospital information system. The medical record number and archive number obtained from OpenClinic GA were then used to locate the physical medical record for data extraction. RESULTS: A total of 1668 trauma patients were transported during the study period. 66.7% were successfully linked to their medical record numbers and archive codes. 94% of these patients were successfully linked to their medical record numbers and archive codes were linked by four or five of the five pre-set identifiers. 945 charts were successfully located and extracted for inclusion in the trauma registry. Record linkage and chart extraction took approximately 1256 h. CONCLUSION: The process of record linkage and chart extraction was a resource-intensive process; however, our unique methodology resulted in a high linkage rate. This study suggests that it is feasible to create a retrospective trauma registry in LMICs using pragmatic and locally appropriate record linkage techniques.

INTRODUCTION: Les blessures sont responsables de 10% de la charge mondiale de morbidité, résultant sur environ 5,8 millions de décès par an. Les registres des traumatismes constituent un outil important pour le développement d'un système sur les traumatismes; cependant, les ressources limitées qui caractérisent les pays à revenu faible et intermédiaire font que le développement de registres des traumatismes de qualité est difficile. Nous décrivons le développement d'un registre des traumatismes dans les pays à revenu faible et intermédiaire à partir d'un examen rétrospectif approfondi des dossiers incluant des données tirées des registres pré-hospitaliers, des services d'urgence et des patients hospitalisés. MÉTHODES: Cet article décrit les méthodes dont nous disposons pour identifier et localiser les patients et leurs dossiers médicaux en utilisant des techniques de couplage de dossiers pragmatiques et localement appropriées. Une base de données pré-hospitalières a été interrogée afin d'identifier les patients transportés à l'Hôpital universitaire de Kigali, au Rwanda, de décembre 2012 à février 2015. Les informations démographiques ont été enregistrées et utilisées afin de créer un indice d'identification à cinq facteurs, utilisé ensuite pour mener une recherche dans OpenClinic GA, un système d'information hospitalière en open source accessible en ligne. Les numéros de dossiers médicaux et les codes d'archives obtenu par OpenClinic GA ont été ensuite utilisés pour localiser le dossier médical physique afin d'en extraire les données. RÉSULTATS: Au total, 1668 patients ayant souffert de traumatisme ont été transportés au cours de la période à l'étude. 66,7% ont pu être couplés à leur numéro de dossier médical et code d'archive. 94% de ces patients ont pu être couplés à 4 ou 5 des cinq identifiants préétablis. 945 fichiers ont pu être localisés et extraits pour être intégrés au registre des traumatismes. Le couplage des dossiers et l'extraction des fiches ont nécessité environ 1 256 heures. CONCLUSION: Le processus de couplage de dossiers et d'extraction des fiches a nécessité des ressources considérables; cependant, notre méthodologie unique a résulté sur un taux de couplage élevé. Cette étude suggère qu'il est possible de créer un registre des traumatismes rétrospectif dans les pays à revenu faible et intermédiaire en utilisant des techniques de couplage de dossiers localement appropriées.
