An introduction to the Barell body region by nature of injury diagnosis matrix.

INTRODUCTION: The Barell body region by nature of injury diagnosis matrix standardizes data selection and reports, using a two dimensional array (matrix) that includes all International Classification of Diseases (ICD)-9-CM codes describing trauma. AIM: To provide a standard format for reports from trauma registries, hospital discharge data systems, emergency department data systems, or other sources of non-fatal injury data. This tool could also be used to characterize the patterns of injury using a manageable number of clinically meaningful diagnostic categories and to serve as a standard for casemix comparison across time and place. CONCEPT: The matrix displays 12 nature of injury columns and 36 body region rows placing each ICD-9-CM code in the range from 800 to 995 in a unique cell location in the matrix. Each cell includes the codes associated with a given injury. The matrix rows and columns can easily be collapsed to get broader groupings or expanded if more specific sites are required. The current matrix offers three standard levels of detail through predefined collapsing of body regions from 36 rows to nine rows to five rows. MATRIX DEVELOPMENT: This paper presents stages in the development and the major concepts and properties of the matrix, using data from the Israeli national trauma registry, and from the US National Hospital Discharge Survey. The matrix introduces new ideas such as the separation of traumatic brain injury (TBI), into three types. Injuries to the eye have been separated from other facial injuries. Other head injuries such as open wounds and burns were categorized separately. Injuries to the spinal cord and spinal column were also separated as are the abdomen and pelvis. Extremities have been divided into upper and lower with a further subdivision into more specific regions. Hip fractures were separated from other lower extremity fractures. FORTHCOMING DEVELOPMENTS: The matrix will be used for the development of standard methods for the analysis of multiple injuries and the creation of patient injury profiles. To meet the growing use of ICD-10 and to be applicable to a wider range of countries, the matrix will be translated to ICD-10 and eventually to ICD-10-CM. CONCLUSION: The Barell injury diagnosis matrix has the potential to serve as a basic tool in epidemiological and clinical analyses of injury data.

Non-traumatic lower limb older amputees: a database survey from a geriatric centre.

PURPOSE: The purpose of this survey was to examine the characteristic of a geriatric population admitted for amputation of a lower limb and to explore some of the factors that may affect the course of their hospital stay. METHOD: The study took place in the geriatric division of a tertiary general hospital and included a close geriatric-orthopaedic liaison. Two-hundred and forty-one patients were included in the final analysis. RESULTS: Many above knee amputations were performed, which correlated with advanced age. Rates of in hospital mortality and systemic complications were 16% and 19%, respectively. Thirty-three percent of the patients were discharged back home, and only 6% were supplied with an artificial limb. The general condition of most patients remained poor. CONCLUSION: We conclude that despite a team approach to the care of the geriatric amputee a poor functional result was obtained. By encouraging earlier referrals from the community it is postulated that a reduction in the costly provision of antibiotics would be beneficial and that perhaps lower levels of amputation could be performed thereby enhancing the possibilities for ambulation.

[Structure and process components of trauma care services in emergency departments].

Increasing attention is being paid by staffs of hospitals and directors of our national health agencies to providing emergency medical services for trauma care. The results of a nationwide survey documenting the structure and process components of trauma care in all 24 acute care hospitals in Israel are presented. Although these hospitals provide 24-hour trauma service, there are no formal guidelines for required resources in emergency departments. The results show extreme interhospital variation in physical structure of trauma services and in manpower, protocols and critical resource. However, it is evident that the main focus for intervention in the quality of initial trauma care in hospitals in Israel, is to establish and implement organizational standards.

The effects of powered air supply to the respiratory protective device on respiration parameters during rest and exercise.

The common chemical warfare protective masks impose an excessive respiratory load on the wearer due to elevated breathing resistance and increased dead space. For patients with severe respiratory disease, the excessive respiratory effort may be intolerable. Besides, the substantial negative pressure created within the mask during inspiration may result in an inward leakage in individuals having difficulties with proper facial fitting of the mask. The purpose of the current investigation was to evaluate the effects of a blower, actively driving air, through the mask's filter, at a flow (mean +/- SD) of 42 +/- 2 L/min, on respiratory parameters during rest and moderate exercise. Ten healthy subjects of either sex participated in two experimental sessions, wearing the mask with and without the blower. Each session included 6 min of sitting at rest and 6 min of walking on a treadmill (3.2 mph, and 10 percent grade). In nine of the subjects, the active air supply produced a positive inspiratory pressure at rest (5 +/- 4 vs -24 +/- 9 mm H2O peak inspiratory pressure with and without the blower, respectively, p < 0.0001). Inspiratory carbon dioxide concentration (FICO2) at rest was diminished (0.4 +/- 0.4 vs 1.3 +/- 0.7 percent with and without the blower, respectively; p < 0.01) while FIO2 increased from 19.5 +/- 0.7 percent to 20.6 +/- 0.4 percent with the device (p < 0.01). These changes were associated with a significant decrease in respiratory rate (15 +/- 2 vs 18 +/- 3 per minute, p < 0.01). During exercise the blower barely decreased the negative inspiratory pressures, had no effect on other respiratory parameters measured, but significantly shortened the inspiratory/cycle-length time ratio (0.46 +/- 0.03 vs 0.53 +/- 0.03, p < 0.005). The effects of active air supply were not different between male and female subjects. We conclude that the blower is expected to be a useful accessory to respiratory protective devices for patients with pulmonary disease.

Hybrid functional electrical stimulation orthosis system for the upper limb: effects on spasticity in chronic stable hemiplegia.

A new hybrid functional electrical stimulation orthosis system for the upper limb has been designed to allow for ease of use in the home as a daily treatment modality, as well as offer the opportunity for function enhancement. In a pilot study, the system was used by ten patients with chronic stable hemiparesis secondary to cerebral vascular accident and head injuries. The patients were referred by their treating physicians or therapists after meeting the inclusion criteria of good general health, being greater than one year after head injury, or being ten months post-stroke, with no observed neurologic changes in the prior six weeks. Each of these patients had received prolonged physical therapy, either continuous from the initial inpatient rehabilitation treatment or on an intermittent basis over a period of years. The baseline status for factors related to increased muscle tone, i.e., passive range of motion at the wrist and elbow, posture at rest, posture immediately following activity, and spasticity were quantified before the treatment protocol with the functional electrical stimulation orthosis. Active range of motion and tests of functional use of the involved upper limb were also assessed. The patients were instructed in the protocol, trained in the use of the system, and then used the electrical orthosis at home for up to several hours per day. Follow-up assessments were at six months. A statistically significant improvement was noted in all muscle tone/spasticity parameters measured. A separate report will describe the effects on voluntary motion and functional capabilities.
