Maturation process and international accreditation of trauma system in a rapidly developing country

Background

As trauma systems mature, they are expected to improve patient care, reduce in-hospital complications and optimize outcomes. Qatar has a single trauma center, at the Hamad General Hospital, which serves as the hub for the trauma system that was verified as a level 1 trauma system by the Accreditation Canada International Distinction program in 2014. We hypothesized that this international accreditation was a major step, in the maturation process of the Qatar trauma system, that has positively impacted patient care, reduced complications and improved outcomes of trauma patients in such a rapidly developing country.

Methods

A retrospective analysis of data was conducted for all trauma patients who were admitted between 2010 and 2018. Data were obtained from the level 1 trauma center registry at Hamad Medical Corporation. Patients were divided into Group 1- pre-accreditation (admitted from January 2010 to October 2014) and Group 2- post-accreditation (admitted from November 2014 to December 2018). Patients’ characteristics and in-hospital outcomes were analyzed and compared. Data included patients’ demographics; injury types, mechanism and injury severity scores, interventions, hospital stay, complications and mortality (pre-hospital and in-hospital). Time series analysis for mortality was performed using expert modeler.

Results

Data from a total of 15,864 patients was collected and analyzed. Group 2 patients had more severe injuries in comparison to Group 1 (p<0.05). However, Group 2, had a lower complication rate (ventilator associated pneumonia (VAP)) and a shorter mean hospital length of stay (p<0.05). The overall mortality was 8%. In Group 2; the pre-hospital mortality was higher (52% vs. 41%, p = 0.001), while in-hospital mortality was lower (48% vs. 59%) compared to Group 1 (p = 0.001).

Conclusions

The international recognition and accreditation of the trauma center in 2014 was the key factor in the maturation of the trauma system that improved the in-hospital outcomes. Accreditation also brought other benefits including a reduction in VAP and hospital length of stay. However, further studies are required to explore the maturation process of all individual components of the trauma system including the prehospital setting.

Análisis bibliométrico de la Revista Española de Documentación Científica desde su inclusión en la Web of Science (2008-2018)

En este trabajo se presenta un análisis bibliométrico del contenido científico de la Revista Española de Documentación Científica durante el periodo 2008-2018, usando como metodología el análisis de rendimiento y los mapas de la ciencia. En los resultados se muestran, por un lado, algunos de los indicadores bibliométricos de rendimiento básicos, como son: número de documentos publicados, citas obtenidas, evolución del Factor de Impacto, Índice-h, así como los autores más productivos y más citados y la distribución geográfica de las publicaciones. Por otro lado, este análisis muestra la evolución conceptual de la revista basada en los mapas de la ciencia. En la discusión se comparan estos resultados con otros estudios anteriores, que existen sobre la revista, de evolución temática, y sobre la documentación a nivel nacional e internacional. Se concluye indicando cuales son los autores, países y las dos grandes áreas temáticas que destacan en esta revista: bibliometría y web.

Knowledge mapping of hospital accreditation research: a coword analysis

PURPOSE

Hospital accreditation has been adopted internationally as a way and solution for healthcare quality improvement in hospitals. The purpose of this study was to review and knowledge mapping of bibliographic data about "Hospital Accreditation" and assess the current quantitative trends.

DESIGN/METHODOLOGY/APPROACH

Scientometric methods and knowledge visualization using the coword analysis techniques conducted in three steps based on the data related to the field of hospital accreditation from 1975 to 2018 obtained from the MEDLINE database. Bibliographic data for titles, abstracts and keywords articles were saved in CSV format and MEDLINE templates by applying filters. Data extracted were exported into an Excel spreadsheet and were preprocessed. The authors applied the text mining and visualization using VOSviewer software.

FINDINGS

Hospital accreditation studies have been increased rapidly over the past 30 years. 6,661 documents in the field of hospital accreditation had been published from 1975 to 2018. Hospitals or organizations active in the field of hospital accreditation were in the United States, Italy and Canada. The 10 most productive authors identified in the area of hospital accreditation with a higher influence were identified. "The United States", "accreditation", "Joint commission on accreditation" and "quality assurance, healthcare" had, respectively, the highest frequency. The cluster analysis identified and categorized them into four major clusters. Hospital accreditation field had a close relationship with the quality improvement, patient safety, risk and standards.

ORIGINALITY/VALUE

Hospital accreditation had focused on the scopes of implementation of accreditation programs, adherence to JCI standards, and focus on safety and quality improvement. Future studies are recommended to be conducted on design interventions and paying attention to all dimensions of hospital accreditation.
