EMS response to an airliner crash.

This report of an aircraft crash at a major airport in Kingston, Jamaica examines the response of the local Emergency Medical Services (EMS). Factors that impacted the response are discussed, and the need for more disaster simulation exercises is highlighted. The objective of this case report was to document the response of EMS personnel to the crash of American Airlines Flight 331, and to utilize the information to examine and improve the present protocol. While multiple errors can occur during a mass-casualty event, these can be reduced by frequent simulation exercises during which various personnel practice and learn designated roles. Efficient triage, proper communication, and knowledge of the roles are important in ensuring the best possible outcome. While the triage system and response of the EMS personnel were effective for this magnitude of catastrophe, more work is needed in order to meet predetermined standards. Ways in which this can be overcome include: (1) hosting more disaster simulation exercises; (2) encouraging more involvement with first responders; and (3) strengthening the links in the local EMS system. Vigorous public education must be instituted and maintained.

Prevalence of carotid stenosis in a high-risk Caribbean population.

BACKGROUND AND PURPOSE: The purpose of this study was to determine the prevalence of carotid stenosis among patients presenting to the University Hospital of West Indies (UHWI) Accident and Emergency Department (A&E) with an ischemic stroke or transient ischemic attack (TIA). METHODS: Beginning in August 2006, all patients presenting to the UHWI A&E with an acute stroke or TIA were screened for enrollment. Patients were excluded if they had a hemorrhagic stroke or if informed consent could not be obtained. Demographic and clinical information were collected by chart review and interviewer-administered questionnaires. All participants had noncontrast head computed tomography (CT) and bilateral carotid duplex ultrasounds. RESULTS: 133 patients were enrolled in the study. 90% presented with a stroke and 10% with a TIA. Mean age was 64 years, 52% were male, 96% self-identified as black. 78% had diabetes mellitus or hypertension or both, 27% were current or past smokers. 65.1% had a normal carotid ultrasound, 28.5% had <50% stenosis, 1.6% had 50% to 69% stenosis, 0.8% had >or=70% stenosis to near occlusion, 1.6% had near occlusion and 1.6% total occlusion. CONCLUSIONS: The prevalence of moderate or high-grade carotid stenosis in this high-risk black Caribbean population presenting with an ischemic stroke or a TIA is 5.6%. This is lower than that described in other populations. Further studies are needed to determine the cost-effectiveness of routine screening for carotid stenosis in this population.

Examination of the management of traumatic brain injury in the developing and developed world: focus on resource utilization, protocols, and practices that alter outcome.

OBJECT: We evaluated management and outcome of traumatic brain injury (TBI) in a developed country (US) and a developing country (Jamaica). METHODS: Data were collected prospectively at Grady Memorial Hospital (GMH) in the US and at University Hospital of the West Indies (UHWI) and Kingston Public Hospital (KPH) in Jamaica between September 1, 2003, and September 30, 2004. RESULTS: Complete data were available for 1607 patients. Grady Memorial Hospital had a higher proportion of females (p = 0.003), and patients were older at GMH (p = 0.0009) compared with patients at KPH and UHWI. The most common mode of injury was a motor vehicle accident at KPH and GMH (42 and 66%, respectively) and assaults at UHWI (37%). Grady Memorial Hospital admitted more patients with severe head injuries (25.5%) than KPH (18.5%) and UHWI (14.4%). More CT scans were performed (p < 0.0001) and a higher proportion of patients were admitted to the intensive care unit (p < 0.0001) at GMH. There were no statistically significant differences in median days in the intensive care unit among the 3 hospitals. Patients experienced statistically significant differences in days undergoing ventilation between GMH, KPH, and UHWI (p = 0.004). Intracranial pressure monitoring was performed in 1 patient at KPH, in 6 at UHWI, and in 91 at GMH. There were 174 total deaths, but no statistically significant differences in mortality rates between the 3 sites (p = 0.3). Hospital location and TBI severity were associated with a decreased risk of mortality; patients with severe TBI at GMH had a 53% decrease in the risk of mortality (odds ratio = 0.47, p = 0.04). Patients at GMH had lower mean Glasgow Outcome Scale scores (p < 0.0001) and lower Functional Independence Measure self-feed (p = 0.0003), locomotion (p = 0.04), and verbal scores (p < 0.0001). CONCLUSIONS: Despite the availability of advanced technology and more aggressive neurological support at GMH, the overall mortality rate for TBI was similar at all locations. Patients identified with severe TBI had a significantly decreased risk of mortality if they were treated at GMH compared with those patients treated at hospitals in the developing world.

Emergency department physician training in Jamaica: a national public hospital survey.

BACKGROUND: Emergency Department (ED) medical officers are often the first medical responders to emergencies in Jamaica because pre-hospital emergency response services are not universally available. Over the past decade, several new ED training opportunities have been introduced locally. Their precise impact on the health care system in Jamaica has not yet been evaluated. We sought to determine the level of training, qualifications and experience of medical officers employed in public hospital EDs across the nation. METHODS: A database of all medical officers employed in public hospital EDs was created from records maintained by the Ministry of Health in Jamaica. A specially designed questionnaire was administered to all medical officers in this database. Data was analyzed using SPSS Version 10.0. RESULTS: There were 160 ED medical officers across Jamaica, of which 47.5% were males and the mean age was 32.3 years (SD +/- 7.1; Range 23-57). These physicians were employed in the EDs for a mean of 2.2 years (SD +/- 2.5; Range 0-15; Median 2.5) and were recent graduates of medical schools (Mean 5.1; SD +/- 5.9; Median 3 years).Only 5.5% of the medical officers had specialist qualifications (grade III/IV), 12.8% were grade II medical officers and 80.5% were grade I house officers or interns. The majority of medical officers had no additional training qualifications: 20.9% were exposed to post-graduate training, 27.9% had current ACLS certification and 10.3% had current ATLS certification. CONCLUSION: The majority of medical officers in public hospital EDs across Jamaica are relatively inexperienced and inadequately trained. Consultant supervision is not available in most public hospital EDs. With the injury epidemic that exists in Jamaica, it is logical that increased training opportunities and resources are required to meet the needs of the population.

Advancement of laparoscopic surgery in Guyana: a working model for developing countries.

In the late 20th century, the volume and complexity of laparoscopic operations being performed have increased worldwide. However, surgical practice lagged behind in the Caribbean region. This article reports a tailored approach to initiate advanced laparoscopy in Guyana, which can be used as a model to initiate laparoscopic services in other developing nations. This can be achieved in four stages: 1) relying on regional proctors to teach laparoscopic techniques adapted to resource-poor environments, 2) focusing on developing skill sets such as laparoscopic suturing in order to rely less on expensive consumables, 3) creating partnerships that include all stakeholders, and 4) collaborating with regional experts as a valuable resource for continued medical education, multidisciplinary support, and sharing learning experiences.

Hand hygiene compliance by health care workers at a teaching hospital, Kingston, Jamaica.

INTRODUCTION: Consistent practice of hand hygiene (HH) has been shown to reduce the incidence and spread of hospital acquired infections. The objectives of this study were to determine the level of compliance and possible factors affecting compliance with HH practices among HCWs at a teaching hospital in Kingston, Jamaica. METHODOLOGY: A prospective observational study was undertaken at the University Hospital of the West Indies (UHWI) over a two weeks period. Trained, validated observers identified opportunities for hand hygiene as defined by the WHO "Five Hand Hygiene Moments" and recorded whether appropriate hand hygiene actions were taken or missed. Observations were covert to prevent the observer's presence influencing the behaviour of the healthcare workers (HCWs) and targeted areas included the intensive care units (ICUs), surgical wards and surgical outpatient departments. A ward infrastructure survey was also done. Data were entered and analysed using SPSS version 16 for Windows. Chi-square analysis using Pearson's formula was used to test associations between 'exposure' factors and the outcome 'compliance'. RESULTS: A total of 270 hand hygiene opportunities were observed and the overall compliance rate was 38.9%. No differences were observed between the various types of HCWs or seniority. HCWs were more likely to perform hand hygiene if the indication was 'after' rather than 'before' patient contact (p = 0.001). CONCLUSION: This study underscores the need for improvement in HH practices among HCWs in a teaching hospital. Health education with particular attention to the need for HH prior to physical contact with patients is indicated.

Epidemiology of tetanus in Jamaica, 1993-2010.

BACKGROUND: Although tetanus is still endemic in Jamaica, the epidemiologic profile has not been evaluated. METHODS: Admission registers at the main tertiary referral hospital were accessed to identify all patients diagnosed with tetanus from 1 January 1993 to 1 December 2010. RESULTS: There were 26 cases of tetanus (annual incidence of 0.57 cases per 1,000,000 population). Tetanus was more common in men (5.2:1) at a mean age of 59 ± 18.1 years. Persons in high-risk occupations (farmers, gardeners and construction workers) accounted for 52% of cases. CONCLUSIONS: Tetanus remains endemic in Jamaica, occurring more commonly in elderly men. Doctors should be educated about the importance of a high index of suspicion, an immunisation history and promoting booster shots in high-risk groups.

Overcoming obstacles to establish a multidisciplinary team approach to hepatobiliary diseases: a working model in a Caribbean setting.

INTRODUCTION: By providing a structured forum to exchange information and ideas, multidisciplinary team meetings improve working relationships, expedite investigations, promote evidence-based treatment, and ultimately improve clinical outcomes. METHODS: This discursive paper reports the introduction of a multidisciplinary team approach to manage hepatobiliary diseases in Jamaica, focusing on the challenges encountered and the methods used to overcome these obstacles. CONCLUSION: Despite multiple challenges in resource-limited environments, a multidisciplinary team approach can be incorporated into clinical practice in developing nations. Policy makers should make it a priority to support clinical, operational, and governance aspects of the multidisciplinary teams.

From the patient's perspective: is there a need to improve the quality of informed consent for surgery in training hospitals?

OBJECTIVE: This study was performed to evaluate the presurgical informed consent process at a training hospital in Jamaica. METHODS: A postoperative survey was administered to all consecutive able and willing adult patients who underwent the presurgical informed consent process with surgical residents during a 5-week period. Information was collected on patient demographics and patients' perception and satisfaction with the informed consent process. RESULTS: There were 210 surveys completed. Patients were unaware of the training status of the physician involved with their presurgical informed consent process in 48% of cases. Nineteen (9%) patients were instructed to sign a consent document without any discussion. An attempt was made to secure a signature after some discussion with the remaining 191 patients. Patients reported that details of the operation were discussed 74% of the time; potential benefits of the surgery, 72% of the time; potential morbidity, 84% of the time; potential mortality, 19% of the time; predicted postoperative course, 49% of the time; projected recovery, 26% of the time; and other treatment options, 33% of the time. Forty-five patients believed that they were instructed to sign the consent document with minimal discussion. At termination of the consent process, only 70% of the 210 patients reported that they signed the consent form voluntarily. Overall, 67% of patients thought the current informed consent process was unsatisfactory. CONCLUSION: The current informed consent process in use in the surgical training program at the University Hospital of the West Indies requires improvement to meet expected ethical and legal standards.

Infection control practice in the operating room: staff adherence to existing policies in a developing country.

CONTEXT: Infection control interventions are important for containing surgery-related infections. For this reason, the modern operating room (OR) should have well-developed infection control policies. The efficacy of these policies depends on how well the OR staff adhere to them. There is a lack of available data documenting adherence to infection control policies. OBJECTIVE: To evaluate OR staff adherence to existing infection control policies in Jamaica. METHODS: We administered a questionnaire to all OR staff to assess their training, knowledge of local infection control protocols, and practice with regard to 8 randomly selected guidelines. Adherence to each guideline was rated with fixed-choice items on a 4-point Likert scale. The sum of points determined the adherence score. Two respondent groups were defined: adherent (score > 26) and nonadherent (score ≤ 26). We evaluated the relationship between respondent group and age, sex, occupational rank, and time since completion of basic medical training. We used χ(2) and Fisher exact tests to assess associations and t tests to compare means between variables of interest. RESULTS: The sample comprised 132 participants (90 physicians and 42 nurses) with a mean age of 36 (standard deviation ± 9.5) years. Overall, 40.1% were adherent to existing protocols. There was no significant association between the distribution of adherence scores and sex (p = 0.319), time since completion of basic training (p = 0.595), occupational rank (p = 0.461), or age (p = 0.949).Overall, 19% felt their knowledge of infection control practices was inadequate. Those with working knowledge of infection control practices attained it mostly through informal communication (80.4%) and self-directed research (62.6%). CONCLUSION: New approaches to the problem of nonadherence to infection control guidelines are needed in the Caribbean. Several unique cultural, financial, and environmental factors influence adherence in this region, in contrast to conditions in developed countries.

Leadership in surgery for public sector hospitals in Jamaica: strategies for the operating room.

The barriers to health care delivery in developing nations are many: underfunding, limited support services, scarce resources, suboptimal health care worker attitudes, and deficient health care policies are some of the challenges. The literature contains little information about health care leadership in developing nations. This discursive paper examines the impact of leadership on the delivery of operating room (OR) services in public sector hospitals in Jamaica.Delivery of OR services in Jamaica is hindered by many unique cultural, financial, political, and environmental barriers. We identify six leadership goals adapted to this environment to achieve change. Effective leadership must adapt to the environment. Delivery of OR services in Jamaica may be improved by addressing leadership training, workplace safety, interpersonal communication, and work environment and by revising existing policies. Additionally, there should be regular practice audits and quality control surveys.

Revisiting current strategies for primary prevention of motorcycle collisions in Jamaica.

Motorcycle Road Traffic Collisions place a heavy burden on emergency medical services in Jamaica. We explore the existing strategies and legislative policies that may prevent or reduce the severity of these injuries in Jamaica. This is an important aspect of health care as it may minimize the impact of these preventable injuries on the limited resources of the health services.

Informed consent from patients participating in medical education: a survey from a university hospital in Jamaica.

BACKGROUND: Medical students at the University of the West Indies receive clinical training by passing through a series of hospital rotations at the University Hospital of the West Indies (UHWI). Many of these patients are unaware that medical students may be involved in their care. We performed this study to determine patient awareness and their willingness to participate in research and teaching activities. FINDINGS: All consecutive patients admitted to the UHWI between May 1, 2006 and May 29, 2006 who required elective or emergency surgical procedures were prospectively identified These patients were interviewed using a standardised pre-tested questionnaire about their knowledge and willingness to have medical students participate in the delivery of their hospital care. Data was analyzed using SPSS Version 12.0. There were 83 (39.5%) males and 127 (60.5%) females interviewed. The patients were unaware of the grade of the medical professional performing their interview/examination at admission in 157 (74.8%) cases or the grade of medical professional performing their operations in 101 (48.1%) cases. Only 14 (6.7%) patients were specifically asked to allow medical students to be present during their clinical evaluation and care. When specifically asked, 1 patient declined. Had they been asked, 196 (93.3%) patients would have voluntarily allowed medical student involvement. Only 90 (42.9%) patients were made aware that they were admitted to an academic centre with research interests. Only 6 (6.7%) patients declined. Had they been asked, 84 (93.3%) patients would be willing to participate in teaching or research projects. CONCLUSIONS: As medical educators, we are responsible to adhere to ethical and legal guidelines when we interact with patients. It is apparent that there is urgent need for policy development at the UWI to guide clinicians and students on their interactions with patients.

The impact of helmets on motorcycle head trauma at a tertiary hospital in Jamaica.

BACKGROUND: Although the Jamaica road traffic act mandates motorcycle riders to wear approved helmets, opponents suggest that the local road conditions obviate any benefits from helmet use that have been proven in Developed countries. They suggest that the narrow, winding, poorly surfaced, congested local highways do not allow motorcyclists to sustain high velocity travel. The accidents then tend to occur at lower speeds and are accompanied by less severe injuries. This study was carried out to determine the impact of helmet use on traumatic brain injuries from motorcycle collisions in patients admitted to a tertiary referral hospital in Jamaica. METHODS: A prospectively collected trauma registry maintained by the Department of Surgery at the University Hospital of the West Indies in Jamaica was accessed to identify all motorcycle collision victims from January 2000 to January 2007. The therapeutic outcomes of traumatic brain injuries were compared between helmeted and un-helmeted riders. The data was analyzed using SPSS Version 12. RESULTS: Of 293 motorcycle collision victims, 143 sustained brain injuries. There were 9 females (6.3%) with an average age of 23 +/- 7.3 years and 134 males (93.7%) at an average age of 33.4 +/- 11.2 years (mean +/- SD). Only 49 (34.3%) patients wore a helmet at the time of a collision. Helmet use at the time of a collision significantly reduced the severity of head injuries (28.6% vs 46.8%, P = 0.028) and the likelihood of sustaining intra-cranial lesions (26.5% vs 44.7%, P = 0.03) from head injuries. CONCLUSION: Wearing a helmet at the time of a motorcycle collision reduces the severity of head injuries. However, the prevalence of helmet use at the time of a collision is unacceptably low.

Inter-hospital transfer of trauma patients in a developing country: a prospective descriptive study.

UNLABELLED: There is no standardised protocol for the transfer of injured patients in Jamaica, a process that is well known to be potentially hazardous. We undertook this study to evaluate the inter-hospital transfer process of injured patients in this developing country. MATERIALS AND METHODS: A prospective descriptive analytical study of all consecutive patients transferred to the University Hospital of the West Indies from other hospitals was conducted over six months. Data were collected on specially designed proformas and analysed using SPSS version 10.0. RESULTS: Of 122 patients studied, 79.5% were male and the mean age was 27.8+/-20.7 years. Most injuries resulted from road traffic accidents (40.2%), falls (27.1%) and assaults (26.2%). Several problems with the transfer process were identified. There was poor documentation of clinical parameters at referring institutions, with records of pulse rates in 13.1% (16/122), blood pressure in 9.8% (12/122), respiratory rate in 9.8% (12/122), Glasgow Coma Score in 10.6% (13/122) and pupillary reaction in 4.9% (6/122) of cases. Transfer arrangements were made by junior medical officers in 93.4% (114/122) of cases while consultants requested only 3.3% (4/122) of transfers. Public hospital ambulances transported 91.8% (112/122) of patients and 7.4% (9/122) were transported by helicopter. These vehicles were equipped with facilities for oxygen administration in 99.2% (121/122) of cases and sphygmomanometers in 91% (111/122) of cases, but functional capacity for suction was only present in 50% of vehicles. These critically ill patients were accompanied by physicians in only 11.5% (14/122) of cases, while 68.9% (84/122) were accompanied only by nurses. CONCLUSIONS: The transfer of injured patients is not being performed in a manner consistent with modern medical practice. There is urgent need for implementation of a standardised protocol for the transfer of such patients in Jamaica.

An appraisal of smear diagnosis in neurosurgical biopsies - abstract

The neurosurgeon needs rapid tissue diagnosis during surgery to plan the extent of the operation if the exact nature of the lesion is known, to take additional specimens if a previous attempt has failed to be diagnostic and to decide on management if the lesion is non-neoplastic. Rapid tissue diagnosis is mostly offered by frozen sections in various fields of surgery. However, neuro-surgical biopsies are generally multiple, tiny fragments of gelatinous tissue, mostly inappropriate for frozen sections. Smear technique for tissue diagnosis has been in use since 1930 and is routinely used for neurosurgical diagnosis in many European centres. It was started at the University Hospital of the West Indies in 1981. To evaluate the accuracy of the technique we analyzed smear diagnoses and compared them with paraffin section diagnoses. The results were compared with similar studies from other parts of the world. One hundred and forty-four biopsies, comprising 133 intracranial and 11 spinal biopsies, were analyzed. The correct diagnosis was made in 93 percent of cases. The conditions encountered were mainly neoplastic. In 10 cases, there were discrepancy between smear and paraffin section diagnosis. In 8 of the 10 cases, the error was in properly classifying the tumour and did not have any immediate significance on the management. Only in two cases could the error have had a management implication. There was no false negative and only one false positive when a meningioma was diagnosed on superficial biopsy material and on subsequent analysis of more specimen proved to be an inflammatory pseudo-tumour. The diagnostic accuracy (93 percent) was in keeping with similar studies from Europe and North America. The technique is simple, rapid, sensitive, accurate and appropriate for rapid diagnosis of neurosurgical biopsies. (AU)

Brain Abscess at the University Hospital of the West Indies

Surgical infections of the central nervous system are still attended by high rates of morbidity and mortality, although substantial progress has been made since the advent of computed tomography (CT) scanning technology. In this retrospective review of 25 surgically treated patients with either brain abscess of subdural empyema at the University Hospital of the West Indies, the majority of patients were male and between the ages of 10 and 30 years with a mean age of 16.9 years. Almost half the patients had a hemiparesis on presentation while 60 percent had fever. Subdural empyema was more common than a localised intracerebral abscess which was most frequently located in the frontal lobe. The most common predisposing factors were sinusitis and congenital heart disease. Streptococci spp and Staphylococci spp were the most frequently isolated organisms. All patients underwent CT scanning and surgical intervention. The mortality rate was 20 percent, and 21 percent of the survivors had late seizures. There must be a high index of clinical suspicion and early referral to specialist centres where neuroradiological investigation and prompt neurosurgical intervention can be carried out to minimise morbidity and mortality.(Au)

Exotic injuries of the central nervous system

Head injuries are the most common reason for admission among the injured at the University Hospital of the West Indies. Intentional injuries account for 52 percent of all trauma admissions. We report a unique group of 6 patients with central nervous system injuries, all intentional with the offending weapon in situ on arrival at hospital. 4 patients had weapons embedded in the head: two were knives, and one each was an ice-pick and a harpoon from a fishing device. The two other patients sustained spinal, cord injuries from ice-pick wounds. Principles of management involved radiological assessment of the injury to elucidate the position of the weapon, removal of the weapon under controlled circumstances in the operating theatre suite, prevention of infection and seizure prophylaxis. Operations performed were craniotomy, craniectomy and exploration of the spinal injuries. Two deaths occurred. In one, a spinal abscess developed six months after injury with the patient succumbing to sepsis. The other was an unexplained death following craniotomy and removal of a knive which severed the internal carotid artery. The cost of managing these intentional injuries was far greater than for the average patient and significantly demonstrates the burden on the taxpayer to treat these injuries(AU)
