The purpose of this study was to: (1) explore experiences and responses of staff in caring for sheltered, frail, Hurricane Katrina evacuees; and (2) identify how planning and training can be enhanced for staff who may care for frail older populations during and after disasters.
Methods:
Individual, in-person, semi-structured interviews were conducted with 38 staff members in four nursing homes in Mississippi, sheltering 109 evacuees in November 2005, nine weeks after Hurricane Katrina.Twenty-four were direct care staff, including certified nursing assistants, licensed nurses, dietary aides, and social workers; 14 were support staff, including maintenance and business managers. The number interviewed in each nursing home averaged 9.5 (range 6–15). Using a discussion guide and focusing on their experiences caring for nursing home evacuees, staff were asked to describe: (1) experiences; (2) problems; (3) what helped; and (4) what was learned. Data were processed using grounded theory and thematic analysis. Responses of direct care staff differed in emphasis from those of support staff in several areas; responses from these groups were analyzed separately and together. Three of the researchers identified recurring themes; two organized themes conceptually.
Results:
Staff emphasized providing emotional reassurance to evacuees as well as physical care. Many described caring for evacuees as “a blessing,” saying the experience helped them bond with residents, evacuees, and other staff. However, caring for evacuees was difficult because staff members were extremely anxious and in poor physical condition after an arduous evacuation. Challenges included communicating with evacuees' families, preventing dehydration, lack of personal hygiene supplies, staff exhaustion, and emotional needs of residents, evacuees, and staff. Teamwork, community help, and having a well-organized disaster plan, extra supplies, and dependable staff helped personnel cope with the situation.
Conclusions:
Staff of nursing homes that sheltered Katrina evacuees demonstrated resilience in the disaster's aftermath. Many placed the well-being of residents as their first priority. Results underscore the importance of planning, teamwork, and adequate supplies and staffing. Training for long-term care staff should emphasize providing emotional support as well as physical care for residents and evacuees during and following disasters. Nurses, social workers, and other staff members responsible for promoting emotional well-being for nursing home residents should be prepared to respond to disasters.
The August 2007 earthquake in Peru resulted in the loss of critical health infrastructure and resource capacity. A regionally located United States Military Mobile Surgical Team was deployed and operational within 48 hours. However, a post-mission analysis confirmed a low yield from the military surgical resource. The experience of the team suggests that non-surgical medical, transportation, and logistical resources filled essential gaps in health assessment, evacuation, and essential primary care in an otherwise resource-poor surge response capability. Due to an absence of outcomes data, the true effect of the mission on population health remains unknown. Militaries should focus their disaster response efforts on employment of logistics, primary medical care, and transportation/evacuation. Future response strategies should be evidence-based and incorporate a means of quantifying outcomes.
Gaining an understanding of crowd behavior is important in supporting timely and appropriate crowd management principles in the planning and provision of emergency services at mass gatherings. This paper provides a review of the current understanding of the psychological factors of a crowd within the psychosocial domain as they apply to mass-gathering settings.
It can be concluded from this review that there is a large theory-practice gap in relation to crowd psychology and the mass-gathering setting. The literature has highlighted two important elements of crowd behavior—there must be a “seed” and people must engage. Understanding these behaviors may provide opportunities to change crowd behavior outcomes.
The potential for outbreaks of epidemic disease among displaced residents was a significant public health concern in the aftermath of Hurricane Katrina. In response, the Mississippi Department of Health (MDH) and the American Red Cross (ARC) implemented a novel infectious disease surveillance system, in the form of a telephone “hotline”, to detect and rapidly respond to health threats in shelters.
Methods:
All ARC-managed shelters in Mississippi were included in the surveillance system. A symptom-based, case reporting method was developed and distributed to shelter staff, who were linked with MDH and ARC professionals by a toll-free telephone service. Hotline staff investigated potential infectious disease outbreaks, provided assistance to shelter staff regarding optimal patient care, and helped facilitate the evaluation of ill evacuees by local medical personnel.
Results:
Forty-three shelters sheltering 3,520 evacuees participated in the program. Seventeen shelters made 29 calls notifying the hotline of the following cases: (1) fever (6 cases); (2) respiratory infections (37 cases); (3) bloody diarrhea (2 cases); (4) watery diarrhea (15 cases); and (5) other, including rashes (33 cases). Thirty-four of these patients were referred to a local physician or hospital for further diagnosis and disease management. Three cases of chickenpox were identified. No significant infectious disease outbreaks occurred and no deaths were reported.
Conclusions:
The surveillance system used direct verbal communication between shelter staff and hotline managers to enable more rapid reporting, mapping, investigation, and intervention, far beyond the capabilities of a more passive or paper-based system. It also allowed for immediate feedback and education for staff unfamiliar with the diseases and reporting process. Replication of this program should be considered during future disasters when health surveillance of a large, disseminated shelter population is necessary.
This study was performed in the Finnish Defense Forces to assess the potential applicability and value of short video clips as educational material to teach advanced airway management and as the first means of introducing the use of a laryngeal tube (LT) or an intubating laryngeal mask (ILMA) to inexperienced, military, first-responder trainees with no prior hands-on experience.
Methods:
The 60 non-commissioned medical officers participating in this study were randomly assigned into one of two groups: the LT- and the ILMA-group. After viewing the video clips, the trainees were required to perform 10 consecutive, successful insertions of the given instrument into a manikin. The number and duration of the attempts required prior to the 10 consecutive successful insertions were measured.
Results:
The goal of 10 consecutive successful insertions was attained by all 30 subjects in the LT-group, and by 27 of 29 subjects in the ILMA-group with a maximum of 30 attempts. Improvement in the ease and speed of insertion was evident between the first and last consecutive insertions in both groups.
Conclusions:
“Satisfactory” to “good” skill levels are achieved with the applied video-clip demonstration method, even in inexperienced first-responder trainees lacking previous hands on experience.
The potential for disasters exists in all communities. To mitigate the potential catastrophes that confront humanity in the new millennium, an evidence-based approach to disaster management is required urgently. This study moves toward such an evidence-based approach by identifying peer-reviewed publications following a range of disasters and events over the past three decades.
Methods:
Peer-reviewed, event-specific literature was identified using a comprehensive search of the electronically indexed database, MEDLINE (1956–January 2009). An extended comprehensive search was conducted for one event to compare the event-specific literature indexed in MEDLINE to other electronic databases (EMBASE, CINAHL, AMED, CENTRAL, Psych Info, Maternity and Infant Care, EBM Reviews).
Results:
Following 25 individual disasters or overwhelming crises, a total of 2,098 peer-reviewed, event-specific publications were published in 789 journals (652 publications following disasters/events caused by natural hazards, 966 following human-made/technological disasters/events, and 480 following conflict/complex humanitarian events).The event with the greatest number of peer-reviewed, event-specific publications was the 11 September 2001 terrorist attacks (686 publications). Prehospital and Disaster Medicine published the greatest number of peer-reviewed, event-specific publications (54), followed by Journal of Traumatic Stress (42), Military Medicine (40), and Psychiatric Services (40). The primary topics of event-specific publications were mental health, medical health, and response. When an extended, comprehensive search was conducted for one event, 75% of all peer-reviewed, event-specific publications were indexed in MEDLINE.
Conclusions:
A broad range of multi-disciplinary journals publish peer-reviewed, event-specific publications. While the majority of peer-reviewed, event-specific literature is indexed in MEDLINE, comprehensive search strategies should include EMBASE to increase yield.
The number of paramedics in Israel is increasing. Despite this growth and important role, the emergency medical organizations lack information about the characteristics of their work.
Objective:
The objective of this study was to examine the characteristics of the paramedics' work, the quality of their working lives, the factors that keep them in the profession, or conversely, draw them away from it.
Methods:
Cross-sectional study conducted through telephone interviews of a random sample of 50% of the graduates of paramedic courses in Israel (excluding conscripted soldiers).
Results:
The factors that attract paramedics to the profession have much to do with the essence of the job—rescuing and saving—and a love of what it involves, as well as interest and variety. Pressures at work result from having to cope with a lack of administrative support, paperwork, long hours, imbalance between work and family life, and salary. They do not come from having to cope with responsibility, the pressure of working under uncertain conditions, and the sudden transition from calm situations to emergencies. Dissatisfaction at work is caused by burnout, work overload, and poor health. Physical and mental health that impedes their ability to work is related to a sense of burnout and the intention to change professions.
Conclusions:
The findings about the relationships between health, job satisfaction, and burnout, coupled with the fact that within a decade, half of the currently employed paramedics will reach an age at which it is hard for them to perform their job, lead to the conclusion that there is a need to reconsider the optimum length of service in the profession. There also is a need to form organizational arrangements to change the work procedures of aging paramedics.
Due to the accelerating global epidemic of trauma, efficient and sustainable models of trauma care that fit low-resource settings must be developed. In most low-income countries, the burden of surgical trauma is managed by non-doctors at local district hospitals.
Objective:
This study examined whether it is possible to establish primary trauma surgical services of acceptable quality at rural district hospitals by systematically training local, non-graduate, care providers.
Methods:
Seven district hospitals in the most landmine-infested provinces of Northwestern Cambodia were selected for the study. The hospitals were referral points in an established prehospital trauma system. During a four-year training period, 21 surgical care providers underwent five courses (150 hours total) focusing on surgical skills training. In-hospital trauma deaths and postoperative infections were used as quality-of care indicators. Outcome indicators during the training period were compared against pre-intervention data.
Results:
Both the control and treatment populations had long prehospital transport times (three hours) and were severely injured (median Injury Severity Scale Score = 9). The in-hospital trauma fatality rate was low in both populations and not significantly affected by the intervention. The level of post-operative infections was reduced from 22% to 10.3% during the intervention (95% confidence interval for difference 2.8–20.2%). The trainees' selfrating of skills (Visual Analogue Scale) before and after the training indicated a significantly better coping capacity.
Conclusions:
Where the rural hospital is an integral part of a prehospital trauma system, systematic training of non-doctors improves the quality of trauma surgery. Initial efforts to improve trauma management in low-income countries should focus on the district hospital.
Correct identification of the J-Point and ST-segment on an electrocardiograph (ECG) is an important clinical skill for paramedics working in acute healthcare settings. The skill of ECG analysis and interpretation is known to be challenging to learn and often is a difficult concept to teach.
Objectives:
The objective of the study was to determine if undergraduate paramedic students could accurately identify ECG ST-segment elevation and J-Point location.
Methods:
A convenience sample of undergraduate paramedic students (n = 148) was provided with four enlarged ECGs (ECG1–4) that illustrated different levels, patterns, and characteristics of ST-segment elevation. Participants were asked to identify whether ST-elevation was present, and if so, height in millimeters (mm) and the correct location of the J-Point.
Results:
There were significant variations in students'accuracy with both J-Point and ST-segment determination. Eleven (10%) students correctly identified the ST-segment being present in all ECGs. Also, ECG 2 reflected 6 mm of ST-elevation; however, only one student correctly identified this. Overall the students were 0.55 mm (95% CI = 0.29–0.81 mm, range = -6.5–5.8 mm) from the J-point on the horizontal and -0.18 mm (95% CI = -0.31–0.04 mm, range = -2.8–2.3 mm) on the vertical axis.
Conclusions:
Undergraduate paramedic students recognize ST-segment elevation. However, inaccuracies occurred with measurements of ST-segment and precise location of J-Points. Errors in ECG analysis may reflect weaknesses in teaching this skill. Consideration should be given to the design of an educational program that can reliably improve performance of this skill.
Some papers send more than just one message. And sometimes, the number of messages is unintentional or at least not explicitly debated in the article. Such papers have been produced before, but perhaps we should elaborate on these imbedded signals.
The primary messages brought forward by this paper include:
1. Non-doctors, if properly trained, but lacking pathophysiological insight, can provide acceptable surgical care and raise the standard of health care;
2. Training in science can be and should be dovetailed into capacity building as an integral part of quality control;
3. Scientific work can be performed outside the laboratory and the established, high-tech hospitals. Science/evidence can be produced where everyday activities occur; and
4. Large Level-1 Trauma Centers probably are cost-ineffective in most low-resource regions as they consume too many resources and most people do not have access to them.
It is important that medical and paramedical teams responding to earthquakes and treating victims understand the following: (1) the definition of an earthquake; (2) the consequences of an earthquake; and (3) the common international terms used.
Earthquake An earthquake is the shaking or trembling of the earth, which may be natural or man-made (e.g., due to atomic explosion) in origin. An earthquake is a sudden, strong movement or slipping of the earth's crust that result in a sudden release of energy. Earthquakes occur at certain locations where the tectonic plates which form the earth's crust, coincide. Populations that live near these zones or on these plates always must be prepared for earthquakes and their consequences. The direct impacts of earthquakes may be seen in several forms, such as shaking, ground ruptures, landslides, avalanches, fires, soil liquefaction, tsunamis, and/or flooding.
Marathons pose many challenges to event planners. The medical services needed at such events have not received extensive coverage in the literature.
Objective:
The objective of this study was to document injury patterns and medical usage at a category III mass gathering (a marathon), with the goal of helping event planners organize medical resources for large public gatherings.
Methods:
Prospectively obtained medical care reports from the five first-aid stations set up along the marathon route were reviewed. Primary and secondary reasons for seeking medical care were categorized. Weather data were obtained, and ambient temperature was recorded.
Results:
The numbers of finishers were as follows: 4,837 in the marathon (3,099 males, 1,738 females), 814 in the 5K race (362 males, 452 females), and 393 teams in the four-person relay (1,572). Two hundred fifty-one runners sought medical care. The day's temperatures ranged from 39 to 73°F (mean, 56°F). The primary reasons for seeking medical were medication request (26%), musculoskeletal injuries (18%), dehydration (14%), and dermal injuries (11%). Secondary reasons were musculoskeletal injuries (34%), dizziness (19%), dermal injuries (11%), and headaches (9%). Treatment times ranged from 3 to 25.5 minutes and lengthened as the day progressed. Two-thirds of those who sought medical care did so at the end of the race. The majority of runners who sought medical attention had not run a marathon before.
Conclusions:
Marathon planners should allocate medical resources in favor of the halfway point and the final first-aid station. Resources and medical staff should be moved from the earlier tents to further augment the later first-aid stations before the majority of racers reach the middle- and later-distance stations.
Among imaging techniques, computed tomography (CT) is a reliable method for detecting intracranial hematomas in patients with head trauma, but it is not generally available in special circumstances like prehospital situations and harsh conditions such as those following an earthquake.
Objective:
The objective of this study is to determine if near-infrared spectroscopy (NIRS) is useful for performing CT scans on patients with closed head trauma that present to medical centers that do not have the ability to perform a CT scan or in prehospital or harsh situations. Near-infrared spectroscopy and CT scan were compared according to sensitivity and specificity.
Methods:
This was an observational, prospective study. One hundred forty-eight patients admitted to Rasool Akram General Hospital in Tehran, Iran with head injuries during a one-month period were studied using NIRS and CT. The observational, prospective study was conducted and sensitivity, specificity, positive and negative predictive values of NIRS were calculated. Chi-square and Kappa analysis was performed, and a p-value <0.05 was considered significant.
Results:
According to the CT scan findings, 54 (36.5%) of the patients developed intracranial hematoma. The NIRS examination showed that 69 patients (46.6%) might have intracranial hematoma. The number of true negatives was 73 and the number of false negatives was six patients. The sensitivity and specificity of NIRS examination was 88.9% and 77.7%, respectively.
Conclusions:
This study speculates that NIRS may be a useful screening tool to detect intracranial hematoma. This capability could be useful in special situations like in a deprived area, medical centers without CT scan capabilities, prehospital situations, and in harsh conditions like those after an earthquake or other disasters that causes increased numbers of victims with closed head trauma.
Tension pneumothorax is the second leading cause of preventable combat death. Although relatively simple, the management of tension pneumothorax is considered an advanced life support skill set. The purpose of this study was to assess the ability of non-medical law enforcement personnel to learn this skill set and to determine long-term knowledge and skill retention.
Methods:
After completing a pre-intervention questionnaire, a total of 22 tactical team operators completed a 90-minute-long training session in recognition and management of tension pneumothorax. Post-intervention testing was performed immediately post-training, and at one- and six-months post-training.
Results:
Initial training resulted in a significant increase in knowledge (pre: 1.3 ±1.35, max score 7; post: 6.8 ±0.62, p < 0.0001). Knowledge retention persisted at one- and six-months post-training, without significant decrement.
Conclusions:
Non-medical law enforcement personnel are capable of learning needle decompression, and retain this knowledge without significant deterioration for at least six months.
In December 2003, the residents of Bam, Iran experienced an earthquake that measured 6.6 on the Richter scale and destroyed >90% of the city. After the assessment and initial treatment of injuries at national and international field hospitals, a considerable number of victims (approximately 12,000) were transferred to tertiary referral hospitals around the country. Objective: This report evaluated the injuries of 854 victims transferred to 12 referral hospitals in Tehran.
Methods:
The demographic data, injury patterns, injury severity score (ISS), diagnosis, treatment, and outcome data of 854 Bam earthquake victims were assessed.
Results:
There were 467 (54.7%) males and 387 (45.3%) females. The mean age of the patients was 29.0 years. Transportation by aircraft was the most common method used for evacuation, which was used to evacuate 555 patients (65%). Fifty-four percent of the victims required initial medical aid at field hospitals before transportation to Tehran. There were 1,322 patients with injuries, of which, fractures of the lower extremities were the most common (331; 25%). Limb fixation was the most commonly performed primary procedure in emergency wards (389 cases, 39.9%). The mean value ±SD for ISS was 6.7 ±5.2. Orthopedic operations were the most frequent surgical procedures performed (195/260 operations, 75%) and the overall mortality rate was 1.6% (n = 14).
Conclusions:
Along with the crucial importance of aid provided by national and international field hospitals in disasters, suitable triage of casualties and preparedness of tertiary referral centers in unaffected regions also play an important role in providing medical care to disaster victims. During these situations, the number of victims cannot be predicted accurately, and sufficient medical care, particularly for orthopedic problems, can be provided by referral centers.
