Study of the severity of musculoskeletal injuries and triage during the 2005 Pakistan earthquake

Management of extremity and pelvic fractures in earthquake: our observations and recommendations

BACKGROUND

Earthquakes frequently cause injuries to the musculoskeletal system. Studies conducted after earthquakes often report on injured limbs, fractures, and surgeries. This study aimed to enhance preparedness for future earthquakes by acquiring knowledge about the prevalence of fractures and the relationship between fracture types and injury mechanisms.

METHODS

A retrospective analysis was conducted on medical records of patients with fractures admitted to our hospital following the 2023 Kahramanmaraş Earthquake. Patients with fractures resulting from traffic accidents or other causes unrelated to earthquakes were excluded. The recorded data included age, gender, fracture site, fracture type, mechanism of injury, date, duration of surgery, and peak creatine kinase (CK) level. The injury mechanisms were classified into four main categories: injured by falling objects, falling while running, falling from height, and being trapped under rubble. The study investigated the relationship between fractures and other factors.

RESULTS

The study included 185 patients with a mean age of 39.62 ± 20.83 years. The most frequent mechanism of injury was being trapped under rubble. In total, there were 214 fractures, with pelvic fractures being the most common (21.50% of all fractures). Tibia fractures were the most common fractures in the lower extremities (15.89%). Women had a significantly higher occurrence of pelvic fractures (33.3%) compared to men (14.5%) (p = 0.003). The frequency of pelvic fractures significantly increased as age decreased (p = 0.007). Patients with pelvic fractures had a significantly greater peak CK concentration (p = 0.006). Open fractures were more common in the first few days, and Kirschner wires were the first treatment applied at a mean of 74 h and external fixators at a mean of 94.3 h.

CONCLUSION

Injuries from falling objects from roofs and jumping from heights are important in earthquakes. In addition to lower extremity fractures, pelvic fractures are common in earthquake disasters. Most pelvic fractures are simple lateral compression fractures and it is important to follow the patients for crush syndrome in the first days instead of focusing on definitive fracture treatment. Open fractures should be prioritized for fracture surgery within the first few days. External fixators and Kirschner wires are recommended. Closed fractures should be treated conservatively and definitive surgical procedures should be postponed to the following weeks.

Lessons learned from health system rehabilitation preparedness and response for disasters in LMICs: a scoping review

INTRODUCTION

Disasters such as earthquakes, conflict, or landslides result in traumatic injuries creating surges in rehabilitation and assistive technology needs, exacerbating pre-existing unmet needs. Disasters frequently occur in countries where existing rehabilitation services are underdeveloped, hindering response to rehabilitation demand surge events.

AIMS

The primary aim of this scoping review is therefore to synthesize the evidence on rehabilitation and assistive technology preparedness and response of health systems in LMICs to the demand associated with disasters and conflict situations. A secondary aim was to summarize related recommendations identified in the gathered literature.

METHODOLOGY

A scoping review was conducted using the Arksey and O'Malley framework to guide the methodological development. The results are reported in accordance with PRISMA-ScR. Four bibliographic databases were used: CINHAL, Cochrane, Pubmed, Scopus and. Key international organisations were also contacted. The search period was from 2010-2022. Eligible publications were categorized for analysis under the six World Health Organization health systems buildings blocks.

RESULTS

The findings of this scoping review suggest that rehabilitation is poorly integrated into health systems disaster preparedness and response in LMICs. Of the 27 studies included in the scoping review, 14 focused on service delivery, 6 on health workforce, 4 on health information systems and 3 on the leadership and governance building block. No study focused on financing nor assistive technology. This review found the most frequently referenced recommendations for actions that should be taken to develop rehabilitation services in disasters to be: the provision early and multi-professional rehabilitation, including the provision of assistive technology and psychological support, integrated community services; disaster response specific training for rehabilitation professionals; advocacy efforts to create awareness of the importance of rehabilitation in disasters; and the integration of rehabilitation into disaster preparedness and response plans.

CONCLUSION

Findings of this scoping review suggest that rehabilitation is poorly integrated into health systems disaster preparedness and response in LMIC's, largely due to low awareness of rehabilitation, undeveloped rehabilitation health systems and a lack of rehabilitation professionals, and disaster specific training for them. The paucity of available evidence hinders advocacy efforts for rehabilitation in disaster settings and limits the sharing of experiences and lessons learnt to improve rehabilitation preparedness and response. Advocacy efforts need to be expanded.

Rescue Robots for the Urban Earthquake Environment

Robotics have important applications in the field of disaster medical rescue. The deployment of urban rescue robots at the earthquake site can help shorten response time, improve rescue efficiency and keep rescue personnel away from danger. This discussion introduces the performance of some robots in actual rescue scenarios, focuses on the current research status of robots that can provide medical assistance, and analyzes the merits and shortcomings of each system. Based on existing studies, the limitations and development directions of urban rescue robots are also discussed.

Effective plans for hospital system response to earthquake emergencies

Hospital systems play a critical role in treating injuries during disaster emergency responses. Simultaneously, natural disasters hinder their ability to operate at full capacity. Thus, cities must develop strategies that enable hospitals' effective disaster operations. Here, we present a methodology to evaluate emergency response based on a model that assesses the loss of hospital functions and quantifies multiseverity injuries as a result of earthquake damage. The proposed methodology can design effective plans for patient transfers and allocation of ambulances and mobile operating rooms. This methodology is applied to Lima, Peru, subjected to a disaster scenario following a magnitude 8.0 earthquake. Our results show that the spatial distribution of healthcare demands mismatches the post-earthquake capacities of hospitals, leaving large zones on the periphery significantly underserved. This study demonstrates how plans that leverage hospital-system coordination can address this demand-capacity mismatch, reducing waiting times of critically injured patients by factors larger than two.

Retrospective Analysis of Injuries and Hospitalizations of Patients Following the 2009 Earthquake of L'Aquila City

The aim of this study was to investigate the injury patterns and the hospitalizations of patients who were admitted to hospital following the 2009 earthquake in the city of L’Aquila, Central Italy. To the best of our knowledge, this is the first study to analyze the patterns of earthquake-related injuries in Italy. We reviewed the hospital discharge data of 171 patients admitted to hospital within the following 96 h from the mainshock. This is an observational and descriptive study: We controlled for variables such as patient demographics, primary and secondary ICD-9-CM (International Classification of Diseases) diagnosis codes in order to identify the multiple injured patients, main type of injury that resulted in the hospital admission, discharge disposition, and average length of stay (LOS). Seventy-three percent of the 171 patients were admitted to hospital on the first day. Multiple injuries accounted for 52% of all trauma admissions, with a female to male ratio of 63% versus 37%. The most common type of injuries involved bone fractures (46.8%), while lower extremities were the most frequently affected sites (38.75%). The average LOS was 12.11 days. This study allows the evaluation of the impact of earthquake-related injuries in relation both to the health needs of the victims and to the use of the health care resources and assistance.

Physical therapy needs for patients with physical function injuries post-earthquake disasters: A systematic review of Chinese and Western literature

BACKGROUND AND PURPOSE

Over the last 500 years, the most earthquakes with 10,000 or more fatalities and the most overall fatalities have occurred in China. Physical therapists must develop a better understanding of the patient and injury types that they are likely to treat post-earthquake disasters. This systematic review of Chinese and Western literature identified the primary patients treated by physical therapists post-earthquake disasters for injuries that negatively impacted physical function, activity, and participation.

METHODS

Comparisons were made between reports of earthquakes in China and reports from the rest of the world combined.

RESULTS

Sixty-seven studies of 71,986 patients (51.8% male) at 40.6 ± 15 years of age were included. Studies were mostly prospective (n = 48, 71.6%). Reports of earthquakes in China represented more recently occurring disasters (p = .003) and more prospective research designs (p = .003). Reports from China also had a higher median fracture number (p = .004). Studies from China used manual muscle testing (p = .02), visual analogue pain scales (p = .008), Barthel index or modified Barthel index (p < .0001), and joint motion assessment (p = .007) with greater frequencies.

DISCUSSION

Physical therapists from China are more likely to treat patients with a fracture; however, physical therapists from both regions are likely to treat patients with general injuries representing poly-trauma to multiple body regions, traumatic brain-closed head injuries, spinal cord injuries, peripheral nerve injuries, and soft tissue injuries.

IMPLICATIONS ON PHYSIOTHERAPY PRACTICE

These data can help improve earthquake disaster planning, infrastructure development, and resource needs assessment effectiveness. More prospective research study designs and more recent earthquake disasters in China are likely associated with greater explicit use of valid and reliable outcome measurements such as joint motion assessment, manual muscle testing, visual analogue pain scale, and the Barthel index or modified Barthel index.

Spinal cord injury rehabilitation and pressure ulcer prevention after the 2005 South Asian Earthquake: a CBR case study from Pakistan

BACKGROUND

The 2005 South Asian earthquake led to large-scale injuries and disabilities in northern Pakistan, which were dealt with using various approaches. In this regard, a community-based rehabilitation approach was initiated in the Muzaffarabad district of Pakistan in early 2006, focused on preventing complications among persons with Spinal Cord Injury. This case study briefly describes its development, aims and service provision components, in addition to the distribution of injuries from the disaster. Pressure ulcer prevention education, its recall and decrease in prevalence over a year are presented as key outcomes and illuminate the process of implementing rehabilitation in this context.

METHODS

This case study presents findings from a larger internal program evaluation in 2010-11. The study design was cross-sectional, to elicit recall of education components and the resulting prevalence of pressure ulcers over the year, in 33 randomly selected persons with Spinal Cord Injury. Outcomes included retention of knowledge about pressure ulcer prevention, practices and reduction in the prevalence of pressure ulcers over the last year. We also conducted a narrative literature review on the types of injuries and complications in the Spinal Cord population from Northern Pakistan.

RESULTS

Hospital cohort studies reported "spine" injuries at 5%, while persons with spinal cord injury were identified as the most underserved needing rehabilitation services after the quake. Results from the evaluation of prevention education revealed that all 33 respondents were trained in detection of pressure ulcers, while 32 recalled "danger signs" for which they would seek immediate help. All correctly recalled postural change timings, however, their actual practices differed. Twenty-seven respondents (82%) reported no pressure ulcers over the last year.

CONCLUSION

The decrease in pressure ulcer prevalence over the last year in persons with spinal cord injury highlights the strengths of the community-based rehabilitation approach, particularly preventive education in geographically challenging and highly resource constrained settings. The research also begins to fill a critical gap in the present literature as most research is limited to hospital based interventions from the first year of the 2005 earthquake. Implications for Rehabilitation Prevention education for targeting pressure ulcers can be effective in reducing incidence of this important complication in persons with spinal cord injury. Community-based rehabilitation approaches can prove beneficial in post-disaster settings, especially in resource constrained settings and difficult hilly terrain. Rehabilitation programs should consider nutrition interventions to reduce multiple pressure ulcers, especially in lower middle income countries.

Toward a US Army Pacific (USARPAC) rapid deployment medical component in support of Human Assistance/Disaster Relief (HA/DR) operations: challenges with "Going in Light"

Background

This article reports the exploratory development and study efforts regarding the viability of a novel “going-in light” or “Going Light” medical component in support of US Army Pacific (USARPAC) Humanitarian Assistance/Disaster Relief (HA/DR) missions, namely, a BLU-MED^® incremental modular equipment package along with a Rapid Deployment Medical Team (RDMT). The study was conducted to uncover a way for the U.S. Army to: (1) better medically support the greater U.S. military Pacific Command, (2) prepare the Army for Pacific HA/DR contingencies, and (3) imprint a swift presence and positive contribution to Pacific HA/DR operations.

Methods

The findings were derived from an intensive quasi-Military Decision Making Planning (MDMP) process, specifically, the Oracle Delphi. This process was used to: (1) review a needs assessment on the profile of disasters in general and the Pacific in particular and (2) critically examine the viability and issues surrounding a Pacific HA/DR medical response of going in light and incrementally.

Results

The Pacific area of operations contains 9 of 15 countries most at risk for disasters in the most disaster-prone region of the world. So, it is not a matter of whether a major, potentially large-scale lethal disaster will occur but rather when. Solid empirical research has shown that by every outcome measured Joint Forces (Army, Navy, Air Force, and Marines) medical HA/DR operations have been inordinately successful and cost-effective when they employed U.S. Army medical assets inland near disasters’ kinetic impact and combined sister services’ logistical support and expertise. In this regard, USARPAC has the potential to go in light and successfully fill a vital HA/DR medical response gap with the RDMT and a BLU-MED^®. However, initially going in fast and light and expanding and contracting as the situation dictates comes with subsequent challenges as briefly described herein that must be addressed.

Conclusions

The challenges to going in light are not insurmountable “show stoppers.” They can be identified and addressed through planning and preparation. Hopefully, the acquisition rapid response light components will equip commanders with more effective options with which to conduct Pacific HA/DR operations and be a focal point for effective joint operations.

Implementation of a triage system in Pakistan: the need of the hour

In today's world, an effective emergency department (ED) cannot function properly without having a triage system. Though available in various forms, this essentially categorises patients according to the seriousness of their condition and the priority of their need.Pakistan is yet to introduce this system and where it exists, it is in its infancy. A disaster-prone country such as ours, which is frequently faced with both man-made and natural calamities, could benefit tremendously from its introduction. The activity of EDs would be streamlined and precious lives would be saved.

Use of external fixators for damage-control orthopaedics in natural disasters like the 2005 Pakistan earthquake

PURPOSE

In the 2005 Pakistan earthquake, the great many injured with multiple fractures and open wounds provided a unique opportunity to practice damage-control orthopaedics. External fixators remain a time-tested tools for operating surgeons on such occasions. The locally manufactured, readily available Naseer-Awais (NA) external fixator filled such needs of this disaster with good outcome.

METHODS

This is a retrospective descriptive study of 19,700 patients that presented over seven months to the two centres established by the lead author (SMA) in Muzaffarabad and Mansehra just one night after the 2005 earthquake. A series of local and foreign orthopaedic surgeon teams operated in succession. The computerised patient data collection of 1,145 operations was retrospectively analysed.

RESULTS

Of the 19,700 patients presenting to the SMA centres, 50% had limb injuries. Total fracture fixations were 1,145, of which 295 were external fixations: 185 were applied on the lower limb and 90 on upper limb, the majority were applied on tibia.

CONCLUSION

External fixators are valuable damage-control tools in natural disasters and warfare injuries. The locally manufactured NA external fixator served the needs of the many limb injuries during the 2005 Pakistan earthquake.

External fixators and sudden-onset disasters: Médecins Sans Frontières experience

PURPOSE

Carrying out osteosynthesis is challenging, and controlling for results and complications is necessary to define the limits of acceptable complications. Within the context of sudden-onset disasters, comparing internal with external osteosynthesis remains controversial.

METHODS

The most recent and significant Médecins Sans Frontières (MSF) experience with osteosynthesis was following the earthquake in Haiti in 2010: 353 external fixators were used in the 12 months following the catastrophe, 62 of which were used in the first month. Carrying out internal osteosynthesis was possible two weeks following the earthquake.

RESULTS

The most common indication for open tibial fracture was Gustillo grade 2 or 3. Conversion rate from external to internal osteosynthesis remains anecdotal for several practical reasons. Advantages and drawbacks of external fixators are discussed in the context of precarious situations frequently encountered by MSF.

CONCLUSIONS

External osteosynthesis as a primary and definitive treatment for open fractures, especially of the leg, remains the most frequently used and best-adapted procedure in the context of sudden-onset disasters, even though not ideal.
