RESUMO

Trauma remains a challenging burden on the often under-funded healthcare systems of developing countries. Ten-year data from the Jamaica Trauma Registry show that trauma accounts for 20% of surgical admissions, with close to 50% being intentional and with a 5% mortality. There is a good opportunity for various preventive programmes to be instituted to reduce the burden of this disease.

RESUMO

OBJECTIVE: To determine the impact of trans-thoracic ultrasound (TTUS) in patients with chest trauma and potential cardiac injuries and to determine the outcome of patients with cardiac injury detected on TTUS. METHOD: Data were obtained from the Trauma Registry for all patients presenting alive to the University Hospital of the West Indies during the 10-year period commencing January 1, 2001 and who were subjected to a TTUS or emergency thoracotomy for cardiac injuries, or had cardiac injuries at postmortem. In addition to demographics, variables analysed included mechanism and site of injury and outcome. RESULTS: Of 405 patients being subjected to a TTUS during the period, 12 (3%) had cardiac injuries. During the same period, 63 patients in the Trauma Registry had proven cardiac injuries. Trans-thoracic ultrasound was thus conducted on 19% of all patients with cardiac injuries. Three patients had positive TTUS but no cardiac injuries. Of the patients with injuries, the mean age was 30.4 years, 92.1% were male and 65% were as a result of stab wounds, while 22% were as a result of gunshot wounds. The right ventricle was the most common site of injury, accounting for 41% of cases, while the left ventricle, both ventricles and other sites accounted for 27%, 17% and 14%, respectively. Ninety per cent of the group was subjected to emergency thoracotomy; mortality of the entire group was 48%, including one patient who had TTUS. CONCLUSIONS: This review demonstrates that cardiac injuries remain lethal, diagnosis is largely clinical and TTUS may be over-utilized, having little impact on clinical outcome of patients presenting with this injury.

RESUMO

This article provides a brief description of the conceptual framework of some specific areas of research carried out either collaboratively or independently in the Emergency Department in an effort to positively impact on health issues in an era of evidence-based medicine. The paper focusses on epidemiological studies of infectious diseases, chronic non-communicable diseases, and a recent update on trauma patterns. Conduction of clinical trials is also highlighted. The role of collaboration in Emergency medicine is also discussed. Research must be developed deliberately to facilitate the primary goal of improved patient care and outcomes. Further recommendations are suggested.

RESUMO

AIM: This study reviewed the operative management and outcome of patients with adult Hirschsprung's disease treated at the University Hospital of the West Indies, Mona, Jamaica. METHOD: The case notes for 11 patients with adult Hirschsprung's disease, treated operatively between January 1986 and December 2007, were reviewed and data on preoperative diagnosis, operative procedures and postoperative complications were retrieved. RESULTS: Diagnosis was by open rectal biopsy in nine patients and by rectal suction biopsy in two patients. The time taken for preoperative bowel preparation ranged from 10 to 35 days, and colostomy was required in three patients to facilitate bowel cleansing. The Soave and Swenson procedures were used in six and five patients, respectively, leading to anastomotic stricture in one patient treated using the Soave procedure and to leakage in two patients treated using the Swenson procedure. All procedures took longer than 300 min, and 300-800 ml of blood or plasma was transfused. CONCLUSION: Therapeutic procedures for adult Hirschsprung's disease may result in life-threatening anastamotic complications. A protective colostomy is recommended when Swenson's procedure is used.

RESUMO

BACKGROUND: Injuries in Jamaica are a major public health problem as demonstrated by a hospital based computerized injury surveillance system established in 1999 that provides a risk profile for injuries. SUBJECTS AND METHOD: Injury data from 2004 were selected to provide an annual profile, as comprehensive injury data were available from nine public hospitals. These nine public hospitals provide care for 70% of the Jamaicans admitted to hospitals annually. RESULTS: Data are presented on unintentional injuries where falls caused 44%, lacerations 27% and accidental blunt injuries were 17% of these. For motor vehicle related injuries, 55% were sustained while commuting by motorcars, 17% while riding motorbikes/bicycles and 16% of those injured were pedestrians. Most violence related injuries were due to fights (76%) with acquaintances (47%) who used sharp objects (40%) to inflict the injury. CONCLUSION: The Jamaica Injury Surveillance System (JISS) data, augmented by data collected on injuries from the health centres and the sentinel surveillance system, give a measure of the magnitude of the impact of injuries on the health services. The JISS provides data on the profile of injuries seen and treated at health facilities in Jamaica. In collaboration with police data and community-based surveys, it can be used to complete the risk profiles for different types of injuries. The data generated at the parish, regional and national levels form the basis for the design and monitoring of prevention programmes, as well as serve to support and evaluate policy, legislative control measures and measures that impact on interventions.

RESUMO

Trauma is a leading cause of morbidity and mortality in developing countries and we reviewed the demographics and cost of trauma in a Jamaican population. This is a retrospective, descriptive analytical study of all trauma patients aged 25 to 29-years who presented to the University Hospital of the West Indies (UHWI) during the study period, January 2001 to December 2005. Data were extracted from the Trauma Registry and analysed. Seven hundred and fifteen patients were included in the specified age group over the five-year period. The median age of the patients was 27 years and the median hospital stay was 3 days. There was a 4:1 ratio of males to females and 49.7% of injuries were caused by penetrating wounds. Motor vehicle accidents occurred in 22.4% of cases. Head injuries occurred in 13.6% of cases, long bone fractures in 16.5% and internal injury to chest or abdominal organs in 15.9% of cases. Craniotomy or thoracotomy was undertaken in 4% of cases, Open Reduction Internal Fixation (ORIF) or bone immobilization in 11% and laparotomy in 8% of cases. The mean injury severity scores (ISS) was 4 while 5% of patients had ISS greater than 15. More than 60% of patients underwent diagnostic X-rays, 8% had abdominal imaging (CT scan or ultrasound) and 9.5% underwent head CT scan. The in-hospital mortality was 4.2%. The median hospital bill charged was US$320.00 and the median amount paid by the patients was US$50.00. At the start of the new millennium, penetrating trauma accounted for almost 50% of cases at UHWI with the majority of costs associated with trauma-care being state funded.

RESUMO

BACKGROUND: Tranexamic acid can reduce bleeding in patients undergoing elective surgery. We assessed the effects of early administration of a short course of tranexamic acid on death, vascular occlusive events, and the receipt of blood transfusion in trauma patients. METHODS: This randomised controlled trial was undertaken in 274 hospitals in 40 countries. 20 211 adult trauma patients with, or at risk of significant bleeding were randomly assigned within 8 h of injury to either tranexamic acid (loading dose 1 g over 10 min then infusion of 1 g over 8 h) or matching placebo. Randomisation was balanced by centre, with an allocation sequence based on a block size of eight, generated with a computer random number generator Both participants and study staff (site investigators and trial coordinating centre staff) were masked to treatment allocation. The primary outcome was death in hospital within 4 weeks of injury, and was described with the following categories: bleeding, vascular occlusion (myocardial infarction, stroke and pulmonary embolism), multiorgan failure, head injury, and other AL analyses were by intention to treat. This study is registered as ISRCTN86750102, Clinicaltrials.gov NCT00375258, and South African Clinical Trial Register DOH-27-0607-1919. RESULTS: 10096 patients were allocated to tranexamic acid and 10 115 to placebo, of whom 10060 and 10067, respectively, were analysed. All-cause mortality was significantly reduced with tranexamic acid (1463 [14.5%] tranexamic acid group vs 1613 [160%] placebo group; relative risk 0.91, 95% CI 085-097; p = 00035). The risk of death due to bleeding was significantly reduced (489 [49%] vs 574 [5-7%]; relative risk 0-85, 95% CI 0.76-0.96; p = 0-0077). CONCLUSION: Tranexamic acid safely reduced the risk of death in bleeding trauma patients in this study On the basis of these results, tranexamic acid should be considered for use in bleeding trauma patients.

RESUMO

There is little data available on the prevalence of motorcycle accidents, their resultant injuries and the demand on the health care services in Jamaica. We performed a descriptive, analytical study to evaluate the extent of this problem and the need for preventative national policy measures. Between 1 January 2000 and 1 January 2007, demographic and clinical data on all motorcycle accident victims admitted to the University Hospital of the West Indies were collected in a prospective database. The data were analysed using the SPSS version 12.0. Of 270 motorcycle accident victims, there were 257 (95.2%) males and 13 (4.8%) females. Overall, 134 (49.6%) victims wore helmets at the time of their accident. The more common injuries were as follows: soft tissue trauma 270 (100%); head injuries 143 (53.0%); long bone fractures 126 (46.7%); abdominal injuries 38 (14.1%); thoracic injuries 71 (26.3%); vascular injuries 11 (4.1%). The mean injury severity score was 9.0 (SD 9.4; Median 8; Mode 4). There were 195 patients needing surgical intervention in the form of orthopaedic operations (94), neurosurgical operations (43), abdominal operations (49) and vascular operations (14). The mean duration of hospitalisation was 10 days (SD 11.2; Range 0-115; Median 6; Mode 3). There were 12 (4.4%) deaths, 9 (75%) due to traumatic brain injuries. Fatal injuries were more common in males (11) and un-helmeted patients (10). Motorcycle accidents take a heavy toll on this health care facility in Jamaica. Measures to prevent motorcycle accidents and reduce consequent injuries may be one way in which legislators can preserve precious resources that are spent during these incidents. This can be achieved through active measures such as educational campaigns, adherence to traffic regulations and enforcement of helmet laws.

RESUMO

Emergency Medicine in Jamaica has evolved rapidly over the past 20 years and has gained recognition as a specialty. A residency training programme has been established, trademark life support courses are now available, moves to develop areas of sub-specialization have begun and an emergency medicine association has been formed. There has been an increase in the diagnostic modalities in the main teaching institution, the University Hospital of the West Indies (UHWI). There is an urgent need for improvements in pre-hospital care. This will require the development of an efficient Emergency Medical Service (EMS). More emphasis and attention is required on disaster medicine, toxicology and trauma. Increased training of emergency physicians and nurses, advances in academia and research, and greater advocacy by local emergency physicians will further advance the specialty.
