Complicated head trauma from machete wounds: the experience from a tertiary referral hospital in Jamaica.

There have been limited reports on machete wounds to the cranium. This study was carried out to document the injury profile in a series of patients who have sustained cranial injuries from machete wounds in this setting. Between 1 January 1998 and 1 January 2008, demographic and clinical data were retrospectively collected from all patients treated with complicated head injuries from machete wounds with at least one of the following clinical or radiological features: a recorded Glasgow Coma Score < 8 at any point during admission; compound skull fractures; protruding brain matter; cerebrospinal fluid (CSF) leaks; intra-cranial bleeding; parenchymal contusions; lacerations and/or oedema. The data were analysed using the SPSS version 12.0. Of the 40 patients with complex injuries to the cranium, there was a 6:1 male preponderance with a mean age of 32.5 ± 13.7 years (Mean ± SD). The injuries included open skull fractures in all the 40 (100%) patients, depressed skull fractures in 20 (50%) patients, CSF leaks in 4 (10%) patients, protruding brain matter in 4 (10%) patients, cerebral contusions in 3 (7.5%) patients and extra cranial injuries in 16 (40%) patients. Tetanus prophylaxis and intravenous antibiotics were administered to all patients, and phenytoin was required in 16 (40%) cases. There were 37 (92%) patients requiring operative intervention at a mean of 10.4 h after presentation (SD ± 18.1; Median 6). The operative procedures included elevation of depressed fractures in 20 (54.1%) patients, dural repair in 10 (27.0%) patients and intra-cranial debridement in 7 (18.9%) patients. There were three deaths (7.5%), and seizures were recorded in 5 (12.5%) cases with no reports of infectious morbidity. Eighty percent of patients had a normal Glasgow outcome score on discharge. Complicated machete head trauma is uncommon at this health care facility in Jamaica. We achieved a satisfactory outcome with aggressive management consisting of prompt assessment of the extent of injury, appropriate antibiotics, anticonvulsants for those with seizures or cortical injury and early operation to decrease the risk of complications.

Motorcycle accident injury profiles in Jamaica: an audit from the University Hospital of the West Indies.

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.

Delays in presentations of stroke patients at the University Hospital of the West Indies.

Thrombolytic therapy has been proven to be beneficial in selected patients with ischaemic strokes. Early diagnosis is paramount because there is a narrow therapeutic window for these patients to derive benefit from thrombolytics. We sought to evaluate the timing of stroke presentations at the University Hospital of the West Indies (UHWI) in order to assess the potential eligibility for definitive therapy A retrospective audit of all consecutive patients who had emergent computed tomographic (CT) scans for suspected ischaemic stroke at the UHWI was performed over a six-month period between February 2006 and July 2006. Data were extracted from the hospital records and analysed using SPSS version 12. There were 331 patients evaluated with brain CT for a clinically suspected stroke during the study period. Complete time documentation and CT scans were available for analysis in 171 patients with ischaemic strokes. The average age was 64.5 years (range +/- SD: 3-98 +/- 19.9 years) with a slight male preponderance (58% vs. 42%). There was considerable pre-hospital delay with 63% of patients presenting more than 12 hours after the onset of symptoms. There were also long inhospital delays. Only 52% of patients were assessed by a physician within an hour of presentation to hospital and only 55% of patients had CT scans completed within three hours of a physician s request. Although thrombolysis is not routinely performed for ischaemic strokes at our institution, sensitization of physicians and the general public in our setting to symptoms and signs of this disease is urgently needed to improve stroke management, whereby definitive treatment can be considered for selected patients.

The aetiology of head injury in admitted patients in Jamaica.

This cross-sectional, descriptive study identified 857 head-injured patients who were admitted to the University Hospital of the West Indies (UHWI) over a four-year period. Their median age (IQR) was 28 (16, 45) years and 629 (73.5%) were males. Median length of hospital stay (IQR) was 2 (1, 6) days. Median ICU stay in the intensive care unit (IQR) was 6 (2, 12) days for the 59 (6.9%) patients admitted there. Most patients (73.3%) were admitted with unintentional injuries resulting from road traffic accidents (48.9%), of which passengers were the most commonly affected, and from falls which occurred in 24.4%. Intentional injuries accounted for 26.7% of those admitted, consisting mainly of assaults with blunt objects in 18.0% (154/857). Penetrating injuries were less common, accounting for 67 (7.8%) injuries. Among these, there were 23 gunshot wounds of the head (2.7%). Head injury in admitted patients is mainly due to road traffic accidents, falls and interpersonal violence. Prevention and interventional strategies including education, law enforcement, physical and social engineering must focus on these aetiologies. Current measures are clearly insufficient and more effective strategies are urgently warranted.

Unnecessary admissions of head-injured patients at the University Hospital of the West Indies.

The prospectively collected data in the Jamaica National Trauma Registry operated by the Section of Surgery identified 88 patients who were admitted with head injury to the University Hospital of the West Indies over a one-year period. There were 67 males (76.1%), the mean (SD) age of the entire group being 35.02 (+/- 18.45) years. Intentional injuries occurred in 47.2%. The Injury Severity Score was greater than 15 in 19.3%, severe head injuries occurred in 19% and overall mortality was 16%. Care in the Intensive Care Unit (ICU) was extended to only half of those with the severe injuries. The Scottish Intercollegiate Guidelines Network (SIGN) method was used to assess the appropriateness of admission to hospital. Sixteen (18%) of the 88 patients were inappropriately admitted according to SIGN guidelines. Increased efficiency may result from standardization of admission criteria for head-injured patients and consistent implementation of the SIGN guidelines for admission without increased risk to patients. This may be expected to minimize unnecessary admissions and result in considerable cost savings.

Surgical and intensive care needs of head-injured patients transferred to the University Hospital of the West Indies.

A cross-sectional, descriptive study utilizing data collected in the 'Trauma Registry' of the Department of Surgery, Radiology, Anaesthesia and Intensive Care at the University Hospital of the West Indies (UHWI) was undertaken to document injury severity, surgical requirements and intensive care needs of head-injured patients transferred to the UHWI over a three-year period Of 144 patients studied, the majority (71%) were young males. Overall, injury tended to be mild Twenty-three patients (16.0%) had severe head injury and 27 patients (18.8%) were admitted to the intensive care unit. Concussion with (33%) or without (36%) skull fracture was the commonest neurological admission diagnosis. Associated non-neurological injuries in 33% were primarily fractures. Fifty-six patients (39%) required surgical intervention. Craniotomies and open reduction and internal fixation of fractures were the commonest procedures. The majority of patients (79.2%) were discharged home; 56 (39%) made a good Glasgow outcome score recovery. Seventeen patients (11.8%) died in hospital. As most of the transferred patients with head injuries in this study had only mild injury, most commonly concussions, and their prognosis was good, we recommend that appropriate educational and training programmes and transfer policies be implemented to minimize inappropriate transfers.

Maternal hydrocephalus in pregnancy and delivery: a report of two cases

We present two cases of maternal hydrocephalus in pregnancy. In one case, the patient had no medical problems and had a spontaneous vaginal delivery of a normal neonate at term. In the second case, the patient had an uneventful pregnancy until 36 weeks when she presented to the labour ward with drowsiness and decreasing consciousness. She only recovered after emergency Caesarean section and revision of her ventriculo-peritoneal shunt. Her neonate although preterm had no anomalies and was sent home soon after birth with the mother.

Presentamos dos casos de hidrocefalia en el embarazo. En uno de los casos, la paciente no presentaba problemas médicos y tuvo un parto vaginal espontáneo de un neonato a término. En el segundo caso, la paciente tuvo un embarazo sin incidentes hasta la semana 36 en que se presentó a la sala de partos con somnolencia y pérdida gradual de la conciencia. Sólo se recuperó luego de una cesárea deemergencia y la revisión de su derivación ventrículo-peritoneal. Su neonato, aunque pre-término, nopresentó anomalías, y fue enviado a casa junto con su madre, poco después de su nacimiento.

Este estudio transversal descriptivo identificó 857 pacientes con lesiones cefálicas, ingresados en el Hospital Universitario de West Indies (UHWI) por un periodo de cuatro años. Su edad mediana (IQR) fue 28 (16, 45) años y 629 (73.5%) eran varones. La longitud mediana de estancia hospitalaria (IQR) fue de 2 (1, 6) días. La estancia mediana en la unidad de cuidados intensivos fue de (IQR) 6 (2, 12) días para los 59 (6.9%) pacientes ingresados allí. La mayoría de los pacientes (73.3%) fueron ingresados con lesiones involuntarias a consecuencia de accidentes de tráfico (48.9%) ­ de los cuales los pasajeros fueron comúnmente los más afectados ­ y de caídas ocurridas en 24.4%. Las lesiones intencionales constituyeron el 26.7% de los casos ingresados, siendo el 18.0% (154/857) producidas principalmente por ataques con objetos contundentes. Las lesiones penetrantes fueron menos comunes, representadas por 67 (7.8%) de las lesiones. De estas, 23 fueron heridas de bala en la cabeza (2.7%). Las lesiones en la cabeza en los pacientes ingresados se debieron principalmente a accidentes de tráfico, caídas y violencia interpersonal. Las estrategias de prevención e intervención ­ incluyendo la educación, la imposición del cumplimiento de la ley, la ingeniería física y social ­ deben centrar su atención en estas etiologías. Las medidas actuales son a las claras insuficientes y se requiere con urgencia estrategias más efectivas

Se llevó a cabo un estudio transversal descriptivo utilizando datos tomados del "Registro de traumas" del Departamento de Cirugía, Radiología, Anestesia y Cuidados Intensivos en el Hospital Universitario de West Indies (HUWI), a fin de documentar la severidad de la lesión, los requerimientos quirúrgicos y las necesidades de cuidado intensivo de pacientes con lesiones cefálicas transferidos al HUWI durante un período de más de tres años. De 144 pacientes estudiados, la mayor parte (71%) eran varones jóvenes. En general, las lesiones tendían a ser leves. Veintitrés pacientes (16.0%) tuvieron lesiones cefálicas severas, y 27 pacientes (18.8%) fueron ingresados a la unidad de cuidados intensivos. Concusión con fractura del cráneo (33%) o sin fractura del cráneo (36%) fue el diagnóstico neurológico más común para el ingreso. Las lesiones no neurológicas asociadas en 33% fueron principalmente fracturas. Cincuenta y seis pacientes (39%) necesitaron intervención quirúrgica. Las craniotomías así como la reducción abierta y la fijación interna de fracturas, fueron los procedimientos más comunes. La mayoría de los pacientes (79.2%) fueron dados de alta; 56 (39%) tuvo una buena recuperación según la puntuación de la escala de Glasgow para la evolución clínica. Diecisiete pacientes (11.8%) murieron en el hospital. Como que la mayor parte de los pacientes transferidos con lesiones de cabeza en este estudio tuvieron solo lesiones leves ­ por lo general concusiones ­ y puesto que su prognosis era buena, recomendamos que se implementen programas adecuados de educación y entrenamiento, así como políticas de transferencia apropiadas, a fin de minimizar las transferencias inadecuadas

En los datos recopilados prospectivamente en el Registro Nacional Jamaicano de Traumas (Jamaica National Trauma Registry), operado por la Sección de Cirugía, se identificaron 88 pacientes que habían ingresado con lesiones cefálicas al Hospital Universitario de West Indies, por un período de más de un año. Había 67 varones (76.1%), y la edad mediana (SD) del grupo en su totalidad fue 35.02 (± 18.45) años. En el 47% ocurrieron heridas intencionales. La Puntuación de Severidad de la Lesión fue mayor de 15 en 19.3%; las lesiones cefálicas severas ocurrieron en 19%, y la mortalidad general fue 16%. El cuidado en UCI se extendió sólo a la mitad de las lesiones severas. El método conocido como Scottish Intercollegiate Guidelines Network (SIGN), se usó para evaluar hasta que punto el ingreso al hospital era adecuado. Dieciséis (18%) de los 88 pacientes fueron ingresados inadecuadamente según los lineamientos de SIGN. Puede producirse un aumento de la eficiencia a partir de la estandardización de los criterios de admisión para los pacientes con lesiones cefálicas y la implementación sistemática de los lineamientos de SIGN para los ingresos, sin aumento de riesgo para los pacientes. Hay razón para esperar que esto minimice los ingresos innecesarios y traiga consigo un ahorro considerable de los costos

The prevalence of seat belt use in Kingston, Jamaica: a follow-up observational study five years after the introduction of legislation / Prevalencia del uso del cinturón de seguridad en Kingston, Jamaica: un estudio observacional de seguimiento, cinco años después de introducida la legislación

An observational cross-sectional study conducted in Kingston in 2004 showed that seat belts were used by 81.2% of private motor vehicle drivers and 74.0% offront seat passengers. This was significantly improved compared to 21.1% and 13.6% respectively in 1996 before the introduction of legislation in 1999 (p < 0.001). Females were significantly more likely than males to wear seat belts, both when driving (92.5% vs 77.3%; p < 0. 001) and as front seat passengers (79.9% vs 66.3%; p < 0.001). Of the 2289 motor vehicles examined, all except one were equipped with seat belts. Rear passenger utilization of seat belts was not examined. Drivers of new vehicles were more likely than other drivers to use seat belts (p < 0.001). Male drivers, drivers of older vehicles and all passengers may require specific targeting in an educational and enforcement campaign if the maximum benefits of seat belt use are to be realized

Un estudio transversal observacional llevado a cabo en Kingston en el año 2004 mostró que los cinturones de seguridad eran usados por el 81.2% de los conductores de vehículos motorizados privados, y el 74.0% de los pasajeros del asiento delantero. Esto representa una mejoría significativa en comparación con el 21.1% y el 13.6% respectivamente en 1996 antes de que se introdujera la legislación en 1999 (p < 0.001). Las tendencia de las mujeres a usar cinturones de seguridad fue significativamente mayor que la de los hombres, tanto al conducir (92.5% vs 77.3%; p < 0.001) como al viajar como pasajeras en el asiento delantero (79.9% vs 66.3%; p < 0.001). De los 2289 vehículos motorizados examinados, todos – excepto uno – estaban equipados con cinturones de seguridad. No se examinó la utilización de los cinturones de seguridad por parte de los pasajeros en los asientos traseros. Los conductores de vehículos nuevos mostraron una tendencia mayor que los otros conductores a usar cinturones de seguridad (p < 0.001). Los conductores varones, los conductores de vehículos más viejos, y todos los pasajeros puede que requieran ser objeto específico de una campaña destinada a educarlos o a hacer cumplir la ley si se desea maximizar los beneficios del uso del cinturón de seguridad.

Transfer of head-injured patients in Jamaica: is there a problem?

Head-injured patients are often transferred to the University Hospital of the West Indies (UHWI) for tertiary care. There is no standardized, agreed protocol governing their transfer. During the three-year period January 1998 to December 2000, 144 head injured patients were transferred to the UHWI from other institutions. They were 70% male, had a mean age of 34 years and spent a mean of 13 days in hospital. Eighteen per cent were admitted to the Intensive Care Unit, where they spent a mean of nine days. On arrival, mean pulse rate was 92 +/- 22 beats/minute, mean systolic blood pressure was 130 +/- 27 mmHg and mean diastolic was 76 +/- 19mmHg. Twenty-eight per cent of patients had a pulse rate above 100/min on arrival and 13.8% had systolic blood pressure below 60 mmHg. The Glasgow Coma Scale score was unrecorded at the referring institution in 70% of cases and by the receiving officers at the UHWI in 23% of cases. Intubation was done on only half of those who were eligible. Junior staff members initiated and carried out transfers whenever this was documented. The types of vehicles and monitoring equipment used could not be determined in most instances. Fifty-eight per cent of patients had minor head injuries, 12%, severe injury and 33%, associated injuries requiring a variety of surgical procedures by multiple specialties. Most patients (80.6%) were discharged home but 11.8% died in hospital. Transfer of head-injured patients, many with multiple injuries is not being performed in a manner consistent with modern medical practice. There is urgent need for implementation of a standardized protocol for the transfer of such patients in Jamaica.

Surgery in the elderly: is age a risk factor?

This prospective, observational one-year study analyzed 623 patients who were 60 years and older, out of a cohort of 2375 patients who were admitted consecutively to the general surgery wards of the University Hospital of the West Indies (UHWI). Even though only 9.7% of the Jamaican population are 60 years and older, this age group accounted for 26.2% of total admissions. Comparison of elderly and non-elderly patients showed no differences in gender, but less elderly patients were emergency admissions (52% vs 64%, p < 0.001), more underwent surgery (68% vs 60%, p < 0.001), their mean hospital stay was longer (11.5 vs 8.0 days, p < 0.001) and their mortality rate was higher (8.8% vs 1.9%, p < 0.001). Emergency admissions (52%) exceeded elective admissions in the elderly. Forty-four (80%) of the 55 deaths in the elderly group were admitted as emergencies compared to elective admissions (p < 0.001). There were 11 deaths among the 296 elective admissions (3.7%) but 44 deaths among the 327 emergency admissions (13.5%), a significant difference in mortality rates (p < 0.001). Overall, the death rate for males was higher. Cancer was the commonest admission diagnosis (21%) and that amongst mortalities. Steps to improve the opportunities for earlier admission and optimization of care of elderly surgical patients would not only benefit them but would be an important step towards a more efficient use of already scarce resources.

Los pacientes con heridas en la cabeza son a menudo transferidos al Hospital Universitario de West Indies (UHWI) para su cuidado terciario. No existe ningún protocolo acordado en relación con las normas que deben regir la transferencia. En el trienio de enero de 1998 a diciembre 2000, 144 pacientes con heridas de cabeza, fueron transferidos al HUWI desde otras instituciones. El 70% de ellos eran varones de 34 años de edad promedio, y el período de permanencia en el hospital fue 13 días como promedio. El 18% fue ingresado en la Unidad de Cuidados Intensivos, donde permaneció un promedio de 9 días. Al llegar al hospital, su pulso medio era de 92 ± 22 pulsaciones/minuto, la presión arterial sistólica media era de 130 ± 27 mmHg, y la media diastólica de 76 ± 19 mmHg. El 28% de los pacientes tenía un ritmo de pulsaciones por encima de 100/min al momento del ingreso, y un 13.8% tenía la presión arterial sistólica por debajo de 60 mmHg. No había constancia de la aplicación de la Escala de Coma de Glasgow en las instituciones que remitieron a los pacientes en el 70% de los casos, ni por parte de los funcionarios médicos que recibieron a los pacientes en el HUWI en el 23% de los casos. La entubación se realizó solamente en la mitad de los pacientes elegibles. El personal subalterno inició y llevó a cabo las transferencias en todos los casos docu-mentados. En la mayor parte de los casos no fue posible determinar los tipos de vehículos ni el equipo de monitoreo utilizados. El 58% por ciento de los pacientes presentaba heridas menores de la cabeza, el 12% tuvo heridas graves, y un 33% acudió con heridas asociadas que requerían diversos procedimientos quirúrgicos de múltiples especialidades. La mayoría de los pacientes (80.6%) regresó de alta a sus casas, pero el 11.8% murió en el hospital. La transferencia de pacien-tes con heridas en la cabeza – muchos de ellos con lesiones múltiples – no se está realizando de manera consistente con la práctica médica moderna...

Este estudio observacional prospectivo de un año analizó 623 pacientes de 60 años de edad o más, de una cohorte de 2375 pacientes que fueron admitidos consecutivamente a las salas de cirugía general del Hospital Universitario de West Indies. Aunque sólo 9.7% de la población jamaicana tiene 60 años de edad o más, este grupo etario representó el 26.2% del total de ingresos. La comparación de pacientes mayores con no mayores no mostró ninguna diferencia en cuanto a género, pero los pacientes menos mayores fueron ingresos de emergencia (52% vs 64%, p < 0.001), más necesitaron cirugía (68% vs 60%, p <0.001), su período medio de estancia en el hospital fue más largo (11.5 vs 8.0 días, p <0.001) y su tasa de mortalidad fue más alta (8.8% vs 1.9%, p < 0.001). Los ingresos de emergencia (52%) excedieron a los ingresos electivos dentro del grupo de los pacientes mayores de edad. Cuarenta y cuatro (80%) de las 55 muertes en el grupo de mayores de edad fueron pacientes ingresados como emergencias en comparación con los ingresos electivos (p < 0.001). Se produjeron 11 fallecimientos entre las 296 admisiones electivas (3.7%) pero 44 muertes entre las 327 admisiones de emergencia (13.5%), una diferencia significativa en la tasa de mortalidad (p < 0.001). Por regla general, la tasa de mortalidad entre los hombres fue más alta. El cáncer fue el diagnóstico más común (21%) entre los ingresos y la causa más frecuente de las mortalidades. Los pasos para mejorar las oportunidades de ingreso temprano y optimizar la atención a pacientes quirúrgicos ancianos, no sólo redundaría en beneficio de estos últimos, sino que representaría también un paso importante hacia un uso más eficaz de recursos que están escasos.

Neuroendoscopy in Jamaica.

This retrospective, descriptive study reviewed the patient profile, disease spectrum, indications for and results of treatment and complications of all 27 patients who had neuroendoscopy at the University Hospital of the West Indies (UHWI) over the three-year period between November 2000, when the service was first introduced, and November 2003. Nineteen (67.9%) were males and eight were females. Their mean age was 27.5 +/- 21.4 years with a range of four months to 70 years. Of the entire group, 20 had hydrocephalus with raised intracranial pressure, of which 15 had endoscopic third ventriculostomy (ETV) for the treatment of obstructive hydrocephalus, using two different techniques for ventricular floor fenestration. There was no demonstrable difference in outcome between the water jet and blunt forceps techniques. Three procedures failed to relieve the hydrocephalus, requiring subsequent ventriculo-peritoneal shunts. Three patients had successful cyst fenestrations. Six patients had endoscope assisted trans-sphenoidal resection for pituitary tumours. There were five complications and no deaths. Mean hospital stay was 18.4 +/- 16.7 days and mean follow-up was 29 weeks. There were no late failures. Neuroendoscopy is the treatment of choice for obstructive hydrocephalus due to aqueduct stenosis or posterior fossa tumours and has the advantage of avoiding shunt related complications. It is safe and effective for the majority of patients and has a significant role in the management of neurosurgical patients in the Caribbean.
