The Red Cross and Red Crescent Health Information System (RCHIS) combines the functionality of an Electronic Medical Record (EMR), Health Information System (HIS), as well as Human Resource and stock management system. Its purpose is to facilitate patient quality of care, early warning for outbreak detection, accountability/reporting, and resource management. Short-term, emergency medical teams and support staff responding to acute clinical needs in a humanitarian context are the intended end users.

To explain the functional design principles and usability testing protocol implemented in initial RCHIS design and development phases to ensure technological fit within the humanitarian medical context.

RCHIS development followed the patient-user journey, with each patient/staff interaction encapsulated by a microservice. The integration of multiple microservices enabled RCHIS to mimic various patient journeys. The functional scope of each microservice was designed by medical end-users and was further used for access management. The value and variable design, including validation rules, were led by health informaticians and existing medical standards. Intuitiveness and ease of use guided User Interface design, with targeted medical end-user feedback collected on a twice-monthly basis in addition to early design workshops, field immersion, and post-development pilot testing.

Support and implementation of RCHIS were not inherently guaranteed. As such, the process of co-designing with end users had the primary benefit of ensuring effective scope and technological fit given the humanitarian context, but also the secondary benefit of improving internal acceptability and advocacy.

The added value of digital health records as a quality assurance mechanism is well documented. However, the increased workload and reduced employment satisfaction affiliated with the rise of EMRs illustrated a need to re-evaluate current design and use within clinical settings. The design and development approach taken for RCHIS is one attempt to improve human-computer interaction in the clinical setting.

In many low-income countries, basic prehospital Emergency Medical Services (EMS) remain under-developed, resulting in significant delays or the complete inability to access care.

The purpose of this study was to analyze the effectiveness of a layperson EMS training targeting motorcycle taxi (boda) drivers in a rural region of Uganda.

Fifty (50) adult boda drivers from Masindi, Uganda were selected for a one-day training course including lectures and simulation. Course content covered basic prehospital skills and transport. Participants were given a first responder kit at completion of the course. Understanding of material was assessed prior to training, immediately after course completion, and four months from the initial course using the same ten question test. Test means were analyzed using a standard linear regression model. At the four-month follow up, all 50 boda drivers participated in semi-structured small group qualitative interviews regarding their perception of the course and experiences implementing course skills in the community. Boda drivers were asked to complete a brief form on each patient transported during the study period. For patients transported to Masindi Kitara Medical Center (MKMC), hospital trauma registry data were analyzed.

Trainees showed both knowledge acquisition and retention with pre-test scores of 21.8% improving to 48.0% at course completion and 57.7% at the four-month follow up. Overall, participant’s scores increased by an average of 35% from the pre-test to the second post-test (P <.001). A total of 69 patient forms were completed on transported patients over the initial four-month period. Ninety-five percent (95%) of these were injured patients, and motorcycle crash was the predominant mechanism of injury (48% of injuries). Eight patients were transported to MKMC, but none of these patients were recorded in the hospital trauma registry. Major barriers identified through semi-structured interviews included harassment by police, poor road conditions, and lack of basic resources for transport. Ninety-four percent (94%) of trainees strongly agreed that the training was useful. Total costs were estimated at $3,489 USD, or $69 per trainee.

Motorcycle taxi drivers can be trained to provide basic prehospital care in a short time and at a low cost. While there is much enthusiasm for additional training and skill acquisition from this cohort, the sustainability and scalability of such programs is still in question.

On 09 April 2004, Typhoon Sudal struck the Island of Yap in the Federated States of Micronesia (FSM). Over 90% of homes, public utilities, and public property were damaged or destroyed. Nearly 10% of the population was displaced to shelters, and the majority of the population was without drinking water or power. United States disaster workers were deployed to Yap for three months to assist in the recovery and relief efforts.

The objective of this study was to evaluate the acute healthcare needs of the US disaster relief population serving in a remote setting with limited medical resources.

A retrospective chart review of all disaster relief workers presenting to an emergency clinic in Yap during the disaster relief effort from April 2004–July 2004 was performed. Investigators extracted demographic data, chief complaints, medical histories, medical management, disposition, and outcome data from the clinic charts.

Together, the 60 disaster workers present on Yap during the relief effort made 163 patient contacts in the disaster emergency clinic. A total of 92% of patient contacts were for minor medical complaints or minor trauma, 13% were for upper-respiratory infections, 9% were for gastrointestinal illness, and 9% were for dermatological problems. Eight percent of visits were for serious medical problems or trauma. Life-threatening illnesses or injuries did not occur.

Disaster relief workers on Yap frequently utilized the disaster relief clinic. In general, disaster workers remained healthy during the relief effort in Yap, and most injuries and illnesses were minor. On-site medical providers resulted in rapid care and stabilization, and after treatment, disaster workers were able to return to duty.

Air medical transport of trauma patients from the scene of injury plays a critical role in the delivery of severely injured patients to trauma centers. Over-triage of patients to trauma centers reduces the system efficiency and jeopardizes safety of air medical crews.

The objective of this study was to determine which triage factors utilized by Emergency Medical Services (EMS) providers are strong predictors of early discharge for trauma patients transported by helicopter to a trauma center.

A retrospective chart review over a two-year period was performed for trauma patients flown from the injury site into a Level I trauma center by an air medical transport program. Demographic and clinical data were collected on each patient. Prehospital factors such as Glasgow Coma Score (GCS), Revised Trauma Score (RTS), intubation status, mechanism of injury, anatomic injuries, physiologic parameters, and any combinations of these factors were investigated to determine which triage criteria accurately predicted early discharge. Hospital factors such as Injury Severity Score (ISS), length-of-stay (LOS), survival, and emergency department disposition were also collected. Early discharge was defined as a hospital stay of less than 24 hours in a patient who survives their injuries. A more stringent definition of appropriate triage was defined as a patient with in-hospital death, an ISS >15, those taken to the operating room (OR) or intensive care unit (ICU), or those receiving blood products. Those patients who failed to meet these criteria were also used to determine over-triage rates.

An overall early discharge rate of 35% was found among the study population. Furthermore, when the more stringent definition was applied, over-triage rates were as high as 85%. Positive predictive values indicated that patients who met at least one anatomic and physiologic criteria were appropriately transported by helicopter as 94% of these patients had stays longer than 24 hours. No other criteria or combination of criteria had a high predictive value for early discharge.

No individual triage criteria or combination of criteria examined demonstrated the ability to uniformly predict an early discharge. Although helicopter transport and subsequent hospital care is costly and resource consuming, it appears that a significant number of patients will be discharged within 24 hours of their transport to a trauma center. Future studies must determine the impact of eliminating “low-yield” triage criteria on under-triage of scene trauma patients.

The Revised Trauma Score (RTS) has been proposed as an entry criterion to identify patients with mid-range survival probability for traumatic hemorrhagic shock studies.

Determination of which of four RTS strata (1-3.99, 2-4.99, 1-4.99, and 2-5.99) identifies patients with predicted and actual mortality rates near 50% for use as an entry criterion in traumatic hemorrhagic shock clinical trials.

Existing database analysis in which demographic and injury severity data from two prior international Diaspirin Cross-Linked Hemoglobin (DCLHb) clinical trials were used to identify an RTS range that could be an optimal entry criterion in order to find the population of trauma patients with mid-range predicted and actual mortality rates.

Of 208 study patients, the mean age was 37 years, 65% sustained blunt trauma, 49% received DCLHb, and 57% came from the European Union study arm. The mean values were: ISS, 31 (SD = 18); RTS, 5.6 (SD = 1.8); and Glasgow Coma Scale (GCS), 10.4 (SD = 4.8). The mean TRISS-predicted mortality was 34% and the actual 28-day mortality was 35%. The initially proposed 1-3.99 RTS range (n = 41) had the highest predicted (79%) and actual (71%) mortality rates. The 2-5.99 RTS range (n = 79) had a 62% predicted and 53% actual mortality, and included 76% blunt trauma patients. Removal of GCS <5 patients from this RTS 2-5.99 subgroup caused a 48% further reduction in eligible patients, leaving 41 patients (20% of 208 total patients), 66% of whom sustained a blunt trauma injury. This subgroup had 54% predicted and 49% actual mortality rates. Receiver operator curve (ROC) analysis found the GCS to be as predictive of mortality as the RTS, both in the total patient population and in the RTS 2-5.99 subgroup.

The use of an RTS 2-5.99 inclusion criterion range identifies a traumatic hemorrhagic shock patient subgroup with predicted and actual mortality that approach the desired 50% rate. The exclusion of GCS <5 from this RTS 2-5.99 subgroup patients yields a smaller, more uniform patient subgroup whose mortality is more likely related to hemorrhagic shock than traumatic brain injury. Future studies should examine whether the RTS or other physiologic criteria such as the GCS score are most useful as traumatic hemorrhagic shock study entry criteria.

To measure blood levels of morphine and additional drugs in patients suspected of intravenous (IV) heroin abuse and to evaluate the effects of antidote treatment.

Prehospital blood sampling in 52 patients.

Forty-five patients were blood-positive for heroin, eight of whom were hospitalized. Forty-one patients also had abused additional drugs: minor tranquilizers, ethanol, amphetamine, cocaine, and/or carbamazepine. Seven patients had taken either only methadone or ketobemidione: one was admitted. Treatment with increasing doses of naloxone indicated a necessity for hospitalization. Six of 14 patients treated with naloxone (1.8 mg were hospitalized. Seven patients had an extremely high blood level of morphine (0.2 mg/kg), that could be reverted with naloxone in moderate doses.

This study indicates that under prehospital conditions, it is difficult to identify a patient intoxicated only with intravenous heroin. Nearly all patients treated were cases of multiple drug/alcohol overdoses. Even the symptoms associated with extremely high blood levels of morphine could be reversed with naloxone in moderate doses.

An earthquake of 9.0 magnitude, followed by a tsunami, hit Japan in 2011 causing widespread destruction. Fukushima Nuclear Power Plant had been damaged, causing a spread of radioactive materials.

The aim of this study was to assess personal willingness to respond to a disaster as a part of an international delegation, to an area with unknown and unclear risk of radioactive materials. The Israeli delegation to the Japan 2011 earthquake had been chosen as a case study.

The survey was conducted during the first two weeks after the tsunami in Japan. The population was selected randomly. After distributing the survey form, 94 anonymous answers were received, which give a 69% participation rate. The sample was divided into two groups (participated or didn't participate in an international delegation in the past).

It was found that as the situation on the ground became worse, the willingness to be deployed dropped dramatically, although no significant difference was found in willingness between the two study groups. When both groups were combined into one group, significant differences were found in their willingness to be deployed in a delegation between the three levels (no radioactive leak, possible radioactive leak, and uncontrolled leak).

The willingness to serve on a delegation that responds to a scene with a potential radioactive leak will be dramatically influenced by the risk at the site.

Latex allergy first was recognized early in the 20th Century, but was not a matter of concern until the last decade of that Century. The reported incidence of latex allergy in different occupations varies considerably. It has been documented in dental workers, operating theater staff, anesthetists, and laboratory technicians. However, little data specifically related to those involved in patient care in the emergency prehospital setting are available.

A questionnaire was distributed to a sample of both volunteer and salaried first responders from St. John Ambulance Australia in South Australia and Western Australia, and the South Australian AmbulanceService. The first responders were surveyed to: (1) determine the incidence of latex allergy; (2) consider possible factors associated with its development; (3) compare characteristics of the surveyed groups; and (4) reinforce the development of an educational program.

The study tool had predetermined statistical qualities. Data were collated and processed using standard statistical procedures. Surveys were collected anonymously.

Of the 2,716 forms distributed, 1,099 were returned, resulting in an overall response rate of 40.5%. Atopy was identified in 14.9% of participants, hand dermatitis in 9.4%, and latex allergy in 6.4%. In the group of full-time ambulance officers, there was a significantly higher incidence of hand dermatitis and latex allergy. There also was a significant relationship between latex allergies and both dermatitis and glove usage (as measured by frequency and duration).

In a group of first responders assessed by an anonymous, voluntary questionnaire, the subset of full-time, salaried ambulance officers was identified as having a higher incidence of hand dermatitis and latex allergy than their volunteer co-workers. These results require further assessment to substantiate the frequency of latex allergy and determine the predisposing factors. All personnel must learn about hand care. Non-powdered, natural rubber latex gloves should be supported for general use in this setting.
