Clinical Informatics and the Electronic Medical Record.

The electronic medical record has fundamentally altered the way surgeons participate and practice medicine. There is now a wealth of data, once hidden behind paper records, that is, now available to surgeons to provide superior care to their patients. This article reviews the history of the electronic medical record, discusses use cases of additional data resources, and highlights the pitfalls of this relatively new technology.

The effect of COVID-19 on burn management and outcomes in a resource-limited setting.

INTRODUCTION: Optimal burn care includes fluid resuscitation and early excision and grafting. During the COVID-19 pandemic, resource-constrained environments were susceptible to interruptions in burn care. We sought to characterize pre- and intra-pandemic burn-associated outcomes at a busy tertiary hospital in Malawi. METHODS: This is a retrospective analysis of burn patients that presented to Kamuzu Central Hospital Lilongwe from 2011 through December 2021. We compared patients based on whether they presented pre- or intra-pandemic, starting on March 11, 2020, the date of official WHO designation. Comparing these cohorts, we used modified Poisson modeling to estimate the adjusted risk of undergoing an operation and the risk of death. RESULTS: We included 2969 patients, with 390 presenting during the pandemic. Patient factors were similar between the cohorts. More patients underwent surgery pre-pandemic (21.1 vs 10.3 %, p < 0.001) but crude mortality was similar at 17.3 % vs. 21.2 % (p = 0.08). The RR of undergoing surgery during the pandemic was 0.45 (95 % CI 0.32, 0.64) adjusted for age, sex, % TBSA, flame burns, and time to presentation. During the pandemic, the risk ratio for in-hospital mortality was 1.23 (95 % CI 1.01, 1.50) adjusted for age, sex, % TBSA, surgical intervention, flame burns, and time to presentation. CONCLUSIONS: During the pandemic, the probability of undergoing burn excision or grafting was significantly lower for patients, independent of the severity. Consequently, the adjusted risk of mortality was higher. To improve patient outcomes, efforts to preserve operative capacity for burn patients during periods of severe resource constraint are imperative.

Validating the danger of vehicular protective devices and bowel injury.

INTRODUCTION: Protective devices such as seat belts and airbags have improved the safety of motor vehicle occupants, but limited data suggest they may be associated with increased blunt bowel (small bowel or colon) injuries (BI). Unfortunately, this risk is unquantified. METHODS: We analyzed the National Trauma Data Bank (2017-2019) using ICD-10 codes to identify adult motor vehicle occupants with BI who underwent surgical repair. We used logistic regression modeling to compare the risk of undergoing surgical repair for BI after using a protective device. RESULTS: Of 2,848,592 injured patients, 475,546 (16.7%) were motor vehicle occupants. Only 1.2% (n = 5627/475,546) of patients underwent a bowel repair or resection. Using a seat belt only was associated with an adjusted OR of 2.09 (95% CI 1.91, 2.28) for undergoing a bowel repair/resection when adjusting for Injury Severity Score (ISS) and age. Airbag deployment without a seat belt had an adjusted OR of 1.46 (95% CI 1.31, 1.62), while both devices combined conferred an OR of 3.27 (95% CI 3.02, 3.54). However, using a seat belt was protective against death with an OR of 0.50 (95% CI 0.48, 0.53), adjusted for age, sex, Charlson Comorbidity Score, and ISS. CONCLUSION: Seat belts and airbags are essential public health safety interventions and protect against death in motor vehicle-associated injuries. However, patients involved in MVCs with airbag deployment or while wearing a seat belt are at an increased risk of bowel injury requiring surgery compared to unrestrained patients, despite these events being relatively uncommon.

Reperfusion repercussions: A review of the metabolic derangements following resuscitative endovascular balloon occlusion of the aorta.

BACKGROUND: Current resuscitative endovascular balloon occlusion of the aorta (REBOA) literature focuses on improving outcomes through careful patient selection, diligent catheter placement, and expeditious definitive hemorrhage control. However, the detection and treatment of post-REBOA ischemia-reperfusion injury (IRI) remains an area for potential improvement. Herein, we provide a review of the metabolic derangements that we have encountered while managing post-REBOA IRI in past swine experiments. We also provide data-driven clinical recommendations to facilitate resuscitation post-REBOA deflation that may be translatable to humans. METHODS: We retrospectively reviewed the laboratory data from 25 swine across three varying hemorrhagic shock models that were subjected to complete REBOA of either 45 minutes, 60 minutes, or 90 minutes. In each model the balloon was deflated gradually following definitive hemorrhage control. Animals were then subjected to whole blood transfusion and critical care with frequent electrolyte monitoring and treatment of derangements as necessary. RESULTS: Plasma lactate peaked and pH nadired long after balloon deflation in all swine in the 45-minute, 60-minute, and 90-minute occlusion models (onset of peak lactate, 32.9 ± 6.35 minutes, 38.8 ± 10.55 minutes, and 49.5 ± 6.5 minutes; pH nadir, 4.3 ± 0.72 minutes, 26.9 ± 12.32 minutes, and 42 ± 7.45 minutes after balloon deflation in the 45-, 60-, and 90-minute occlusion models, respectively). All models displayed persistent hypoglycemia for more than an hour following reperfusion (92.1 ± 105.5 minutes, 125 ± 114.9 minutes, and 96 ± 97.8 minutes after balloon deflation in the 45-, 60-, and 90-minute occlusion groups, respectively). Hypocalcemia and hyperkalemia occurred in all three groups, with some animals requiring treatment more than an hour after reperfusion. CONCLUSION: Metabolic derangements resulting from REBOA use are common and may worsen long after reperfusion despite resuscitation. Vigilance is required to detect and proactively manage REBOA-associated IRI. Maintaining a readily available "deflation kit" of pharmacological agents needed to treat common post-REBOA electrolyte abnormalities may facilitate management. LEVEL OF EVIDENCE: Level V.

Cutaneous leishmaniasis among Syrian refugees in Jordan.

INTRODUCTION: Old World cutaneous leishmaniasis (CL) is one of the most prevalent vector-borne diseases within the World Health Organization's Eastern Mediterranean Region. The conflict in the Syrian Arab Republic generated large population movements and raised concerns about spreading of CL to countries where Syrians have relocated, including Jordan. METHODS: A review of electronic and paper-based registries of CL cases in Jordan was conducted to assess burden of disease and associated socio-demographic factors. RESULTS: Increasing numbers of CL cases have been reported in Jordan between 2010 and 2016 (from 140 to 281), paralleled by significant increases in incidence rate (from 2.09 per 100 000 person-years, 95% CI (1.77-2.47), to 2.87 per 100 000 person-year, 95% CI (2.55-3.22), p = 0.002) and in the proportion of cases who are Syrian (from 8.6%-55.2%, p < 0.001). Syrian refugees have higher odds of presenting with leishmaniasis than Jordanian nationals (adjusted OR 7.1, 95% CI (6.3-8.0), p = 0.000). CONCLUSIONS: Presence of large numbers of Syrian refugees within Jordan has so far not contributed to increased risk of developing CL for Jordanians, however surveillance, diagnosis and case management for CL should be reinforced to meet the increased burden. Electronic surveillance can help identify priority populations and areas for interventions.

Crimean-Congo Hemorrhagic Fever in Dubai, United Arab Emirates, 2010: Case Report.

INTRODUCTION: Crimean-Congo hemorrhagic fever (CCHF) is a severe infectious disease that is not endemic in the United Arab Emirates (UAE). CASE PRESENTATION: We report two cases of confirmed CCHF diagnosed in Dubai, UAE, during Hajj season 2010. Both patients presented with an acute history of high-grade fever, skin rash, and hematemesis. CONCLUSIONS: In spite of maximal supportive measures and intravenous ribavirin therapy, both patients died within a few days from start of illness. More than 250 health care workers came into variable degrees of contact with the index cases, and none of them developed signs or symptoms suggestive of acquiring the illness. Health care workers from nonendemic regions should be aware of zoonotic hemorrhagic fevers imported via infected cattle and ticks and be able to diagnose and properly manage suspected cases in a timely manner. In addition, proper infection-control measures should be undertaken to prevent nosocomial spread of infection.
