The development of postgraduate anaesthesia and intensive care training at the University of the West Indies.

The one-year Diploma in Anaesthetics (DA) was the first postgraduate programme offered by the then Faculty of Medicine of The University of the West Indies (UWI). It was instituted in 1966, when the need for trained physician anaesthetists became paramount. Over 200 physicians have been awarded the DA which was discontinued in 1994. The four-year Doctor of Medicine in Anaesthetics [DM (Anaesthetics)] was commenced in 1974 and continues to train most of the region's physician anaesthetists. The majority of the 119 graduates (as of December 2011) are providing invaluable services to the people of the Caribbean. The time has come for the establishment of a regional certifying body, the Caribbean College of Anaesthetists. This college would determine the standards for the training and clinical practice of anaesthetists as perioperative physicians including: the conduct of anaesthesia, critical care, acute and chronic pain management. It would also facilitate continuing medical education and recertification of all practising anaesthetists within the region.

The role of pre-induction ketamine in the management of postoperative pain in patients undergoing elective gynaecological surgery at the University Hospital of the West Indies.

OBJECTIVES: To determine if a single preoperative dose of ketamine hydrochloride reduces the narcotic analgesic requirements and/or pain scores reported by patients in the first 24 hours postoperatively. METHODS: A single-centred, prospective, case-control study was conducted on 84 patients aged 18-65 years, American Society of Anaesthesiologists (ASA) I and II, undergoing elective gynaecological procedures at the University Hospital of the West Indies (UHWI). Patients were randomly assigned to one of two treatment groups: (a) ketamine group, where patients received intravenous ketamine 0.15 mg/kg pre-induction of anaesthesia; and (b) placebo group, patients received normal saline. The anaesthetic technique was standardized. Postoperatively, patients were interviewed at 15-minute intervals for the first hour then at 2, 4, 6, and 24 hours to determine their pain scores and any side effects. Timing and dose of opioid analgesics were also recorded. RESULTS: The mean cumulative morphine dose over the first 24 hours postoperatively was 29.6 +/- 10.8 mg for the ketamine group and 31.9 +/- 11.2 mg for the placebo group (p = 0.324). There was also no significant difference in pain intensity measured by the visual analogue scale (VAS) between the groups. Patient age and the type of surgery performed were not found to influence pain intensity. The most common adverse effects were nausea and vomiting (32.5%), dizziness (42.2%), drowsiness and sedation (45.8%) with no significant difference between groups. Both groups had an average in-hospital stay of three days postoperatively, however, the patients in the ketamine group reported higher satisfaction scores than those in the placebo group (p = 0.039). CONCLUSION: Despite no significant reduction in postoperative narcotic requirements or pain intensity, more patients who received ketamine reported higher levels of satisfaction with their pain management.

The development of anaesthetic services in Jamaica.

The development of anaesthetic services in Jamaica arose out of the recognition that dedicated physicians offered a better morbidity/mortality profile to patients. From untrained personnel offering anaesthesia at the turn of the 20th century, much progress has been made, such that specialized anaesthetists have been trained for the various surgical subspecialties.

OBJETIVOS: Determinar si una sola dosis preoperativa de hidrocloruro de ketamina reduce los requerimientos de analgésicos narcóticos y/o puntuaciones de dolor reportados por los pacientes en las primeras 24 horas posteriores a la operación. MÉTODOS: Se llevó a cabo un estudio de caso-control, prospectivo, monocéntrico en 84 pacientes de 18-65 anos de edad, sometidas a procedimientos de ginecologia electiva en el Hospital Universitario de West Indies (HUWI). Los pacientes fueron asignados aleatoriamente a uno de dos grupos de tratamiento: (a) grupo ketamina, en el que los pacientes recibieron una preinducción de anestesia de 0.15 mg/kg de ketamina intravenosa; y (b) grupo placebo, en el que los pacientes recibieron una solución salina normal. La técnica anestésica fue estandarizada. Postoperatoriamente, se entrevis-taron los pacientes a intervalos de 15 minutos durante la primera hora, y más tarde a 2, 4, 6, y 24 horas para determinar sus puntuaciones de dolor, y efectos cualesquiera. También se registraron el tiempo y la dosificación de los analgésicos. RESULTADOS: La dosis promedio de morfina cumulativa promedio en las primeras 24 horas posteriores a la operación, fue de 29.6 ± 10.8 mg para el grupo de ketamina; y 31.9 ± 11.2 mg para el grupo placebo (p = 0.324). No hubo tampoco ninguna diferencia significativa entre los grupos, en cuanto la intensidad de dolor medida mediante la escala visual analógica (EVA). No se halló que la edad del paciente y el tipo de cirugia realizada tuvieran influencia en la intensidad de dolor. Los efectos adversos más comúnes fueron náusea y vómito (32.5%), vértigo (42.2%), adormecimiento y sedación (45.8%), sin diferencia significativa entre los grupos. Ambos grupos tuvieron una estancia intra-hospitalaria promedio de tres dias tras la operación. No obstante, los pacientes del grupo de la ketamina reportaron puntuaciones de mayor satisfacción que los del grupo placebo (p = 0.039). CONCLUSIÓN: Si bien no hubo una reducción significativa en cuanto a requerimientos de narcóticos o intensidad de dolor postoperatorios, más pacientes que recibieron ketamina reportaron niveles más altos de satisfacción con el tratamiento del dolor.

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.

Dynamics of antibiotic usage in the intensive care unit at the University Hospital of the West Indies.

OBJECTIVE: To determine antibiotic usage patterns in the Intensive Care Unit (ICU) at the University Hospital of the West Indies (UHWI). METHOD: A cross-sectional, analytical study of consecutive patients admitted to the ICU was conducted between July and December 2007. Exclusion criteria were HIV-positive patients, patients < 12 years and those discharged or who died within 48 hours of admission. Data were collected from medical records, stored and analysed using the SPSS Version 12. RESULTS: Of the 150 eligible patients, 109 had complete data (73%). Mean age was 50.8 +/- 20.7 years, with mean APACHE II score of 15.6 +/- 6.7. Forty-five patients (41.3%) received prophylactic antibiotics, most commonly ceftriaxone (31.7%) and metronidazole (19.0%). Appropriate discontinuation within 24 hours occurred in only 11.1%. Two-thirds of patients (67.9%) were treated with empiric antibiotics, most commonly piperacillin/tazobactam (32.1%), ceftazidime (27.5%) or metronidazole (27.5%). Reasons for empiric choice were primarily coverage of organisms based on presumed source of sepsis (45.6%), and broad spectrum, high-powered coverage (23.5%). Courses ranged from 1 - 42 days and were adequate based on subsequent cultures in 71% of cases. Culture reports took between 2 - 8 days with a mean of 3.7 days to become available. De-escalation was practised in only 2 of 26 (7.7%) cases and intravenous to oral switch therapy in only 3.3%. Thirty-two (29.4%) patients died, with sepsis being a cause in 12 (37.5%). CONCLUSIONS: Improved attention to discontinuation of prophylactic antibiotics, appropriate duration of antibiotic courses and de-escalation are essential if the antibiotic practices in the ICU at the UHWI are to compare favourably with international recommendations.

Interdisciplinary communication in the intensive care unit at the University Hospital of the West Indies.

OBJECTIVE: To assess the perceptions of physicians and nurses working full-time in the Intensive Care Unit (ICU) at the University Hospital of the West Indies (UHWI) regarding interdisciplinary communication. METHOD: A cross-sectional survey of all medical personnel working full-time in the ICU was conducted in January 2008 using a self-administered, validated questionnaire. Data on perceived communication, teamwork and leadership, comprehension of patient care goals, perceived effectiveness and satisfaction were collected and analysed using the SPSS Version 14. Internal reliability was tested using Cronbach's alpha score and differences and correlations were assessed using Pearson's Chi-square and correlation analysis. RESULTS: Ninety-five per cent (105/111) of questionnaires were completed. More doctors than nurses experienced open communication with other staff members (73% vs 32%; p < 0.01), with less openness occurring with increasing seniority. More doctors (53%) than nurses (32%) reported receiving inaccurate information from doctors (p < 0.05), with 67% and 51% respectively receiving incorrect information from nurses (p < 0.05). Communication across shifts was felt to be better amongst doctors than nurses (73% vs 63%). Only 50% of doctors compared to 88% of nurses felt they received relevant information quickly (p < 0.05). More nurses than doctors (86% vs 63%; p < 0.01) felt that they had a good understanding of patient care goals. Negative perceptions of the leadership characteristics of consultants (62% amongst doctors and 74% of nurses) and sisters (79% and 73%, respectively) were high. CONCLUSIONS: Communication within the ICU, UHWI, is unsatisfactory with an overall poor perception of senior leadership. Improvement in staff morale and leadership training may create a working environment where team members can communicate openly without fear of chastisement.

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.

Anaesthetic morbidity at the University Hospital of the West Indies / Morbilidad anestésica en el Hospital Universitario de West Indies: un estudio transversal prospectivo

OBJECTIVE: There is little information on adverse anaesthetic outcomes from the Caribbean. The aim of this study was to investigate the occurrence of anaesthetic morbidity and mortality at the University Hospital of the West Indies (UHWI) and to identify possible risk factors. METHODS: All anaesthetic procedures at the UHWI were monitored for adverse events and patient outcomes for the 12-month period from March 2004 to February 2005. Possible risk factors for these adverse events were assessed using logistic regression. RESULTS: Of 3185 anaesthetic proceduress, the incidence of intra-operative events was 201 per 1000 (95% CI 187, 215); 151 per 1000 being cardiovascular and 26 per 1000 respiratory. Others included excess blood loss and equipment failure, hyperglycaemia, nausea and vomiting. Patients with intraoperative complications were three times more likely to have complications during recovery (OR = 3.35; 95% CI 2.59, 4.33, p < 0.001). The incidence of complications among paediatric patients was 139 per 1000 (95% CI 104, 174) intra-operatively and 58 per 1000 (95% CI 34, 81) during recovery. Risk factors for developing complications (p < 0.05) included age > 50 years, ASA status > II, prolonged anaesthesia, high surgical risk, general or combined anaesthetic techniques, senior anaesthetist, intubated patients and co-morbidities. There were 14 operative mortalities, none of which was anaesthesia-related. CONCLUSION: Anaesthetic complication rates at the UHWI are comparable to those in developed countries, except for higher paediatric complication rates and ICU admissions and lower rates of postoperative nausea and vomiting.

OBJETIVO: Existe poca información sobre resultados anestésicos adversos en el Caribe. El propósito del presente estudio fue investigar la manifestación de la morbilidad y la mortalidad anestésicas en el Hospital Universitario de West Indies (UHWI) e identificar los posibles factores de riesgo. MÉTODOS: Todos los procedimientos anestésicos en el UHWI fueron monitoreados en busca de eventos adversos y resultados con los pacientes, durante un período de 12 meses a partir de marzo del 2004. Los posibles factores de riesgo para estos eventos adversos fueron evaluados mediante regresión logística. RESULTADOS: De 3185 procedimientos anestésicos, la incidencia de eventos intraoperatorios fue de 201 por 1000 (95% CI 187, 215); siendo 151 por 1000 cardiovasculares y 26 por 1000 respiratorios. Otros incluyeron exceso en pérdida de sangre y fallo de equipos, hiperglicemia, náusea, y vómitos. Los pacientes con complicaciones intraoperatorias presentaron una probabilidad de complicaciones tres veces mayor en la fase de recuperación (OR = 3.35; 95% CI 2.59, 4.33, p < 0.001). La incidencia de complicaciones entre pacientes pediátricos fue 139 por 1000 (95% CI 104, 174) intraoperatoriamente y 58 por 1000 (95% CI 34, 81) durante la recuperación. Entre los factores de riesgo que desarrollaban complicaciones (p < 0.05) se hallaban: la edad > 50 años, estatus de ASA > II, anestesia prolongada, alto riesgo quirúrgico, técnicas anestésicas combinadas o generales, anestesiólogos de la tercera edad, pacientes entubados, y comorbilidades. Se produjeron 14 mortalidades operatorias, ninguna de las cuales guardó relación con la anestesia. CONCLUSIÓN: Las tasas de complicación anestésica en UHWI son comparables a las que se producen en países desarrollados, excepto por las tasas de complicación pediátrica más altas, mayor número de ingresos a las UCIs, y tasas más bajas de náuseas y vómitos postoperatorios.

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.

Microbial isolates from patients in an intensive care unit, and associated risk factors.

A retrospective one-year analysis of blood, sputum and urine samples taken from all patients admitted for more than 48 hours to the Intensive Care Unit at the University Hospital of the West Indies (UHWI) was undertaken. Positive trapped sputum cultures were found in 50% of patients, positive blood cultures in 32.7% and positive urine cultures in 23.1%. Gram-negative organisms predominated especially Pseudomonas aeruginosa (41.3%) and Acinetobacter spp (33.5%). Coagulase-negative staphylococcus (20%) and streptococcus group D (18.7%) were the most common gram-positive organisms. The Acinetobacter spp showed marked resistance to most antibiotics except for meropenem (82.7% susceptibility) while P. aeruginosa was most susceptible to ceftazidime (84.4%) and amikacin (89.1%). Both the coagulase-negative staphylococcus and streptococcus group D were relatively sensitive to amoxycillin/clavulanate (80.6% and 79.3% respectively). There was a high incidence of yeast found in sputum (27.1%) and urine (16.8%). Mechanical ventilation was a significant risk factor for developing a positive sputum culture (p = 0.01), this effect being particularly prominent in those ventilated for > 5 days. Central venous pressure lines significantly increased the risk of a positive blood culture (p = 0.005). This increase was seen particularly in those with CVP lines for > 7 days. Other risk factors for developing positive cultures included preadmission infection, antibiotic use just prior to ICU admission, increasing APACHE II score and increasing age.

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.

Triage decisions and outcome among the critically ill at the University Hospital of the West Indies.

The worldwide scarcity of intensive care therapy leads to the rationing of this expensive resource. This prospective study investigates the rationing of intensive therapy at the University Hospital of the West Indies (UHWI) by recording triage decisions for intensive care unit (ICU) admission and the impact of these decisions on patient outcome. Between June 2001 and May 2002, all patients triaged for admission to a multidisciplinary ICU were studied For each patient, data were collected including APACHE II score, ICU resource availability and patient survival. There were 356 eligible requests, and 285 (80%) were admitted to the ICU, with 73 (26%) of these admitted patients receiving intensive care outside of the ICU due to space limitations. The APACHE II score was the strongest predictor of ICU admission, with admission more likely as the score decreased (odds ratio = 0.94, 95% confidence interval 0.91, 0.98, p = 0.001). Of 311 requests considered suitable for admission, 26 (8%) were refused admission due to resource limitations. Mortality among these eligible refusals was 81%, compared to 34% among admitted patients (p < 0.001). Although triage decisions are based predominantly on a patient's disease severity, the demand for ICU space exceeds supply, and patient care is negatively impacted by this imbalance.

Transfer of head-injured patients in Jamaica: is there a problem? / Transferencia de pacientes con heridas de cabeza en Jamaica: ¿hay problema?

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 70male, 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 13.8had systolic blood pressure below 60 mmHg. The Glasgow Coma Scale score was unrecorded at the referring institution in 70of cases and by the receiving officers at the UHWI in 23of 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 11.8died 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.

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...

Microbial isolates from patients in an intensive care unit, and associated risk factors / Aislados microbianos de pacientes en una unidad de cuidados intensivos, y factores de riesgos asociados

A retrospective one-year analysis of blood, sputum and urine samples taken from all patients admitted for more than 48 hours to the Intensive Care Unit at the University Hospital of the West Indies (UHWI) was undertaken. Positive trapped sputum cultures were found in 50of patients, positive blood cultures in 32.7and positive urine cultures in 23.1. Gram-negative organisms predominated especially Pseudomonas aeruginosa (41.3) and Acinetobacter spp (33.5). Coagulase-negative staphylococcus (20) and streptococcus group D (18.7) were the most common gram-positive organisms. The Acinetobacter spp showed marked resistance to most antibiotics except for meropenem (82.7susceptibility) while P. aeruginosa was most susceptible to ceftazidime (84.4) and amikacin (89.1). Both the coagulase-negative staphylococcus and streptococcus group D were relatively sensitive to amoxycillin/clavulanate (80.6and 79.3respectively). There was a high incidence of yeast found in sputum (27.1) and urine (16.8). Mechanical ventilation was a significant risk factor for developing a positive sputum culture (p = 0.01), this effect being particularly prominent in those ventilated for > 5 days. Central venous pressure lines significantly increased the risk of a positive blood culture (p = 0.005). This increase was seen particularly in those with CVP lines for > 7 days. Other risk factors for developing positive cultures included preadmission infection, antibiotic use just prior to ICU admission, increasing APACHE II score and increasing age.

Un análisis retrospectivo de muestras de sangre, esputo y orina tomadas a todos los pacientes ingresados por más de 48 horas en la Unidad de Cuidados Intensivos del Hospital Universitario de West Indies (HUWI) fue realizado por espacio de un año. Se hallaron cultivos de esputo positivos en 50% de los pacientes, cultivos de sangre positivos en el 32.7%, y cultivos de orina positivos en el 23.1%. Hubo predominio de organismos gram-negativos, en especial Pseudomonas aeruginosa (41.3%) y Acinetobacter spp (33.5%). Los estafilococos coagulasa-negativos (20%) y los estreptococos del grupo D (18.7%) fueron los organismos gram-positivos más comunes. Los Acinetobacter spp mostraron marcada resistencia a la mayoría de los antibióticos, salvo al meropenem (82.7% susceptibilidad), mientras P aeruginosa fue muy susceptible a la ceftazidima (84.4%) y a la amikacina (89.1%). Tanto el estafilococo coagulasa-negativo como el estreptococo del grupo D fueron relativamente sensibles a la amoxicilina/clavulanato (80.6% y 79.3% respectivamente). Se halló una alta incidencia de levadura en el esputo (27.1%) y la orina (16.8%). La ventilación mecánica fue un factor de riesgo importante para desarrollar un cultivo de esputo positivo (p = 0.01), siendo este efecto particularmente prominente en los ventilados por > 5 días. Las líneas de la presión venosa central aumentaron significativamente el riesgo de un cultivo de sangre positivo (p = 0.005), haciéndose este incremento particularmente evidente en aquellos con líneas de PVC por > 7 días. Otros factores de riesgo para el desarrollo de cultivos positivos incluyeron las infecciones previas a la admisión, el uso de antibióticos justo antes del ingreso a la UCI, el aumento de la puntuación APACHE II cuenta, y la edad avanzada.

Surgery in the elderly: is age a risk factor? / La Cirugía en los Pacientes Mayores de Edad ¿Es la Edad un Factor de Riesgo?

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

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.

Triage decisions and outcome among the critically ill at the University Hospital of the West Indies / Decisiones de Triage y Resultados Clínicos en los Pacientes Graves del Hospital Universitario de West Indies

The worldwide scarcity of intensive care therapy leads to the rationing of this expensive resource. This prospective study investigates the rationing of intensive therapy at the University Hospital of the West Indies (UHWI) by recording triage decisions for intensive care unit (ICU) admission and the impact of these decisions on patient outcome. Between June 2001 and May 2002, all patients triaged for admission to a multidisciplinary ICU were studied For each patient, data were collected including APACHE II score, ICU resource availability and patient survival. There were 356 eligible requests, and 285 (80%) were admitted to the ICU, with 73 (26%) of these admitted patients receiving intensive care outside of the ICU due to space limitations. The APACHE II score was the strongest predictor of ICU admission, with admission more likely as the score decreased (odds ratio = 0.94, 95% confidence interval 0.91, 0.98, p = 0.001). Of 311 requests considered suitable for admission, 26 (8%) were refused admission due to resource limitations. Mortality among these eligible refusals was 81%, compared to 34% among admitted patients (p < 0.001). Although triage decisions are based predominantly on a patient's disease severity, the demand for ICU space exceeds supply, and patient care is negatively impacted by this imbalance

La escasez mundial de terapia de cuidados intensivos conduce al racionamiento de este recurso costoso. Este estudio prospectivo investiga el racionamiento de la terapia intensiva en el Hospital Universitario de West Indies (HUWI) a partir del registro de las decisiones de triage respecto a los ingresos en la unidad de cuidados intensivos (UCI), y el impacto de estas decisiones en la evolución clínica de los pacientes. Entre junio 2001 y mayo 2002, se estudiaron todos los pacientes seleccionados tras una clasificación de triage para ingresar en una UCI multidisciplinaria. De cada paciente se recopilaron datos que incluían: puntuación APACHE II, disponibilidad de recursos en términos de UCI, y supervivencia del paciente. Se produjeron 356 solicitudes elegibles, de las cuales 285 (80%) obtuvieron ingreso a la UCI, para lo cual fue necesario ofrecer el cuidado intensivo a 73 (26%) de estos pacientes fuera de la UCI, debido a limitaciones de espacio. La puntuación APACHE II fue el predictor mayor en los ingresos a la UCI, siendo el ingreso tanto más probable cuanto menor se hacía la puntuación (odds ratio = 0.94, 95% intervalo de confianza 0.91, 0.98, p = 0.001). De 311 solicitudes para las cuales era aconsejable el ingreso, a 26 (8%) se les negó a la admisión debido a limitaciones de recursos. La mortalidad entre los rechazados elegibles fue de 81%, en contraste con un 34% entre los pacientes ingresados (p <0.001). Aunque las decisiones del triage se basan predominantemente en la gravedad de la enfermedad del paciente, la demanda de espacio para la UCI se halla muy por encima de la oferta, y la atención al paciente se ve afectada negativamente debido a esta falta de equilibrio.
