Global Emergency Medicine: A Review of the Literature from 2018

OBJECTIVES

The Global Emergency Medicine Literature Review (GEMLR) conducts a systematic annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most rigorously conducted and widely relevant research in global EM.

METHODS

An electronic search of PubMed, a comprehensive retrieval of articles from specific journals, and search of the gray literature were conducted. Title and abstracts retrieved by these searches were screened by a total of 22 reviewers based on their relevance to the field of global EM, across the domains of disaster and humanitarian response (DHR), emergency care in resource-limited settings (ECRLS), and emergency medicine development (EMD). All articles that were deemed relevant by at least one reviewer, their editor, and the managing editor underwent formal scoring of overall methodologic quality and importance to global EM. Two independent reviewers scored all articles; editors provided a third score in cases of widely discrepant scores.

RESULTS

A total of 19,102 articles were identified by the searches and, after screening and removal of duplicates, a total of 517 articles underwent full review. Twenty-five percent were categorized as DHR, 61% as ECRLS, and 15% as EMD. Inter-rater reliability testing between the reviewers revealed a Cohen's kappa score of 0.213 when considering the complete score or 0.426 when excluding the more subjective half of the score. A total of 25 articles scored higher than 17.5 of 20; these were selected for a full summary and critique.

CONCLUSIONS

In 2018, the total number of articles relevant to global EM that were identified by our search continued to increase. Studies and reviews focusing on pediatric infections, several new and traditionally underrepresented topics, and landscape reviews that may help guide clinical care in new settings represented the majority of top-scoring articles. A shortage of articles related to the development of EM as a specialty was identified.

Functional and Quality of Life Outcomes of a Hand Surgery Mission to Honduras

Background: The objective of this study was to assess functional, quality of life, and satisfaction outcomes of a hand surgery short-term surgical mission (STSM) to Honduras, and determine whether patient demographics and surgery characteristics during a surgical mission correlate with outcome. Methods: A total of 63 patients who received upper extremity surgery at a week-long hand surgery STSM to Honduras in March 2013 participated in the study. A before-after study design was used. Before receiving surgery, participants completed the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire and the Short Form 12 Health Survey version 2 (SF12v2). Four months postoperatively, participants completed the QuickDASH, SF12v2, and Satisfaction Survey. Results: The mean QuickDASH score significantly improved preoperatively to postoperatively. Demographics measures of age, sex, education, and income did not correlate with QuickDASH scores. Preoperative QuickDASH statistically significantly correlated with surgery type: Carpal tunnel patients had the highest scores (worst functioning). Postoperatively, mass excision and scar contracture/skin graft patients were correlated with the lowest scores. Carpal tunnel and tendon surgery patients showed greatest correlation with QuickDASH improvement. SF-12 scores revealed improvements in mental domains and declines in physical domains. Conclusions: Hand surgery performed during STSMs can result in significant functional improvement, regardless of socioeconomic status. Patients benefited from both simpler and more complex operations. Four months after surgery, general health-related quality of life measures showed improved mental indices. Measured physical indices declined despite improved QuickDASH scores. This may be due to the early general postoperative state. Further outcome research in STSMs in additional countries and specialties is required to expand our conclusions to other STSM contexts and guide best practices in STSMs.

Medical respite programs for homeless patients: a systematic review

Medical respite programs provide care to homeless patients who are too sick to be on the streets or in a traditional shelter, but not sick enough to warrant inpatient hospitalization. They are designed to improve the health of homeless patients while also decreasing costly hospital use. Although there is increasing interest in implementing respite programs, there has been no prior systematic review of their effectiveness. We conducted a comprehensive search for studies of medical respite program outcomes in multiple biomedical and sociological databases, and the grey literature. Thirteen articles met inclusion criteria. The articles were heterogeneous in methods, study quality, inclusion of a comparison group, and outcomes examined. Available evidence showed that medical respite programs reduced future hospital admissions, inpatient days, and hospital readmissions. They also resulted in improved housing outcomes. Results for emergency department use and costs were mixed but promising. Future research utilizing adequate comparison groups is needed.
