Major Incident Hospital Simulations in Hospital Based Health Care: A Scoping Review.

Major incidents are occurring in increasing frequency, and place significant stress on existing health-care systems. Simulation is often used to evaluate and improve the capacity of health systems to respond to these incidents, although this is difficult to evaluate. A scoping review was performed, searching 2 databases (PubMed, CINAHL) following PRISMA guidelines. The eligibility criteria included studies addressing whole hospital simulation, published in English after 2000, and interventional or observational research. Exclusion criteria included studies limited to single departments or prehospital conditions, pure computer modelling and dissimilar health systems to Australia. After exclusions, 11 relevant studies were included. These studies assessed various types of simulation, from tabletop exercises to multihospital events, with various outcome measures. The studies were highly heterogenous and assessed as representing variable levels of evidence. In general, all articles had positive conclusions with respect to the use of major incidence simulations. Several benefits were identified, and areas of improvement for the future were highlighted. Benefits included improved understanding of existing Major Incident Response Plans and familiarity with the necessary paradigm shifts of resource management in such events. However, overall this scoping review was unable to make definitive conclusions due to a low level of evidence and lack of validated evaluation.

Analysis of agriculture-related life-threatening injuries presenting to emergency departments of rural generalist hospitals in Southern Queensland.

OBJECTIVE: Agricultural industries are among the most dangerous in Australia posing significant public health risks. This study analyses the nature and management of agriculture-related injuries presenting to EDs in selected hospitals in Southern Queensland. METHODS: Data on agricultural injury presentations over a 6 month period was collected at four rural hospitals by a dedicated onsite hospital data coordinator. Additionally, in two of the participating hospitals all injury presentations over the same 6 month period were recorded. A pre-tested survey instrument, modified for rural settings and designed and developed to export the abstracted data using an iPad application was used as the survey tool. RESULTS: The incidence of agriculture-related injuries was 11% of all injuries, most were males (73%), averaging 40 years. On presentation, 66.5% (n = 234) were categorised as imminently or potentially life threatening with 44% of those patients presenting to hospital ED >3 h after the injury. Large animals were more commonly reported as involved in the aetiology of the presenting injury, particularly using horses and handling cattle. CONCLUSIONS: Agricultural injuries are a significant group of primary care presentations to rural hospitals and training and resourcing for rural hospitals should reflect this. A better understanding of common injury types can lead to efficient allocation of available resources in rural hospitals and potentially improve ED practices. The delay in presentation must be considered in response planning both by farmers and hospital EDs.

A comprehensive review of motor innervation of the hand: variations and clinical significance.

PURPOSE: The objective of the present review is to assemble the recognized anatomical variations, classifications, and clinical evidence with regard to innervation of the hand and discuss the clinical significance of these variations. METHODS: The material for this review was obtained by exploring PubMed and Google Scholar (search terms: hand innervation, variations of ulnar nerve, variations of median nerve, variations of radial nerve) as well as from standard anatomy texts. This initial search returned approximately 300 articles, which was reduced by abstract or title review. Reviewing the reference lists of significant papers uncovered further studies missed in the initial search. A few standard anatomy texts were also consulted for normal anatomy. RESULTS: The median and ulnar nerves frequently display a number of significant deviations from the traditionally taught branching patterns. The traditionally taught innervation of the hand is also found to be highly variable. This is especially evident with regard to the motor innervation of thenar muscles. These variations may be explained by the often under-recognized anastomoses that exist in the hand, such as the motor Riche-Cannieu Anastomosis. Some of these variations are associated significant clinical consequences. CONCLUSIONS: The median and ulnar nerves display many anatomical variations, often with significant clinical implications. Awareness about these variations is clinically important when interpreting clinical examination findings, electrophysiological and radiological investigation as well as during management of patients in terms of surgical and anesthetic procedures.

Lisfranc injuries.

BACKGROUND: Injury to the tarsometatarsal joint is a relatively rare occurrence that is commonly missed, leading to debilitating outcomes. For this reason, it is considered a red flag in general practice. OBJECTIVE: This article reviews the current literature on tarsometatarsal injuries and describes clinical assessment, imaging and management. DISCUSSION: Lisfranc injuries refer to the displacement of the metatarsals from the tarsus, with special attention placed on the second tarsometa-tarsal joint and Lisfranc ligament. These injuries can occur in numerous circumstances, such as motor vehicle accidents, crush inju-ries and falls. Indirect mechanisms include axial force through the foot or twisting on a plantar flexed foot. Suggestive examination signs include plantar ecchymosis, mid-foot pain and positive findings in the provocative tests described in the article. Weight-bearing radiographs are vital for diagnosis. Correct and prompt management is key to avoiding posttraumatic arthritis, a devastating but common complication of Lisfranc injuries.
