Restructuring in health care does not have to compromise the pursuit of clinical excellence and quality patient care. The clinical advancement program (CAP) at the Hospital for Special Care is a newly developed multidisciplinary reward and recognition program for clinical staff. The program is integrated into the hospital's structure of service line management and, unlike traditional advancement programs, is open to all levels of care providers: professional personnel, technical staff, and aides. This article describes the basic features of the CAP model and how it was developed by a multidisciplinary task force.  相似文献

Context:

Two methods have been proposed to transfer an individual in the prone position to a spine board. Researchers do not know which method provides the best immobilization.

Objective:

To determine if motion produced in the unstable cervical spine differs between 2 prone logrolling techniques and to evaluate the effect of equipment on the motion produced during prone logrolling.

Design:

Crossover study.

Setting:

Laboratory.

Patients or Other Participants:

Tests were performed on 5 fresh cadavers (3 men, 2 women; age = 83 ± 8 years, mass = 61.2 ± 14.1 kg).

Main Outcome Measure(s):

Three-dimensional motions were recorded during 2 prone logroll protocols (pull, push) in cadavers with an unstable cervical spine. Three equipment conditions were evaluated: football shoulder pads and helmet, rigid cervical collar, and no equipment. The mean range of motion was calculated for each test condition.

Results:

The pull technique produced 16% more motion than the push technique in the lateral-bending angulation direction (F1,4 = 19.922, P = .01, η2 = 0.833). Whereas the collar-only condition and, to a lesser extent, the football-shoulder-pads-and-helmet condition demonstrated trends toward providing more stability than the no-equipment condition, we found no differences among equipment conditions. We noted an interaction between technique and equipment, with the pull maneuver performed without equipment producing more anteroposterior motion than the push maneuver in any of the equipment conditions.

Conclusions:

We saw a slight difference in the motion measured during the 2 prone logrolling techniques tested, with less lateral-bending and anteroposterior motion produced with the logroll push than the pull technique. Therefore, we recommend adopting the push technique as the preferred spine-boarding maneuver when a patient is found in the prone position. Researchers should continue to seek improved methods for performing prone spine-board transfers to further decrease the motion produced in the unstable spine.Key Words: injuries, transfer techniques, logroll

Key Points

  • A slight difference in motion was measured between the 2 prone logrolling techniques, with the push technique producing less lateral-bending and anterior-posterior motion than the pull technique.
  • The logroll push technique should be adopted as the preferred spine-boarding maneuver when a patient is found in the prone position.
  • Individuals who may need to perform this rescue procedure should practice and become proficient in the logroll push technique.
  • Researchers should continue to seek improved methods for transferring patients positioned prone to spine boards to further reduce the motion transmitted to the unstable spine.
Each year, 12 000 incidents of nonfatal spinal cord injury are reported in the United States.1 Approximately 8.0% of these injuries occur during sport participation.1 Of all US sports, American football has by far the greatest number of spinal injuries. Between 1982 and 2007, the incidence of direct injuries in males playing American football was 1.89 per 100 000 participants in a college setting and 0.75 per 100 000 participants in a high school setting.2The prehospital management of spinal cord injuries is critical to prevent exacerbation of the injury. In 3% to 25% of patients, neurologic deterioration occurs during the initial management of spinal cord injuries.3 During immobilization and transportation of the patient to the hospital, precautions must be taken to transmit as little motion as possible to the spine. One of the first transfers that rescuers must perform is placing the injured athlete onto a long, rigid spine board. When the injured athlete is supine, lift-and-slide spine-board transfers produce less motion in the spine than logroll spine-board transfers.46 However, when the patient is found in the prone position, a lift-and-slide transfer cannot be performed successfully, and a logroll technique must be used.Swartz et al7 recommended how to best manage a catastrophic spine injury in the athlete. They described 2 techniques for logrolling an athlete who is positioned prone: the prone logroll push and the prone logroll pull. Researchers8 have shown that the logroll push produces less motion in the unstable thoracolumbar spine. No one knows which of the prone spine-boarding techniques provides the best immobilization in the unstable cervical spine. Therefore, the primary purpose of our study was to determine if motion produced in the unstable cervical spine differs between 2 prone logrolling techniques. Our null hypothesis was that no difference would exist in the amount of motion allowed between the 2 prone logrolling techniques. Our secondary purpose was to evaluate the effect of equipment on the motion produced during the prone logrolling technique. Our null hypothesis was that no difference would exist in the amount of motion allowed among any of the equipment conditions.  相似文献

OBJECTIVE: To determine if there were differences in concentric peak torque/body-weight (PT/BW) ratios and concentric time to peak torque (TPT) of the dorsiflexors and evertors in uninjured and functionally unstable ankles using a stretch-shortening cycle (SSC) protocol on an isokinetic dynamometer. DESIGN AND SETTING: We employed a case-control study design to examine the test subjects in a climate-controlled athletic training/sports medicine research laboratory. SUBJECTS: Thirty subjects volunteered to participate in this study, 15 with unilateral functional ankle instability and 15 matched controls. MEASUREMENTS: Participants were assessed isokinetically using an SSC protocol for the dorsiflexors and evertors at 120 and 240 degrees.s(-1), bilaterally. Strength was assessed using PT values normalized for body mass. Concentric TPT measurements were also compared between the groups. RESULTS: No differences in concentric PT/BW ratios or concentric TPT were evident between the groups (P >.05). Additionally, there were no differences in these measurements between the ankles for the same motion and speed between the ankles in the subjects with functional instability. CONCLUSIONS: Using the SSC protocol as a measure of ankle function and the stretch-reflex phenomenon, we found no evidence to support the notion that differences in strength and TPT in the active, conscious state exist between those with functional ankle instability and a group of healthy control subjects.  相似文献

BACKGROUND: There have been reports of overhand throwing athletes having decreased joint position sense in their dominant shoulder as compared with the nondominant shoulder. Very little research, however, exists concerning joint position sense in the female athlete. HYPOTHESIS: Female softball athletes have decreased joint position sense in their dominant shoulder as compared with their nondominant shoulder. STUDY DESIGN: Factorial design with investigation of multiple independent variables. METHODS: Joint position sense was assessed in 50 female softball players and 50 nonthrowing female athletes by using an inclinometer during four glenohumeral joint motions. Both the dominant and nondominant shoulders were assessed and error scores were calculated to describe joint position sense. Data were collected during the course of a fall semester and analyzed by using a mixed model analysis of variance with repeated measures on the dependent variable (error scores). RESULTS: A significant group by movement interaction was observed, with the softball athletes demonstrating significantly greater external rotation error scores than the nonthrowing athletes. CONCLUSION: We failed to reject the null hypothesis. Increased error scores (less joint position sense) were observed in both arms of subjects in the softball group. Clinical Relevance: This study suggests that there is decreased shoulder proprioception in asymptomatic female athletes involved in overyhand throwing sports, which may predispose them to injury.  相似文献

Patients with congestive heart failure (CHF) need considerable education to enable them to provide effective self-care for their chronic illness. No information has been published about the learning needs of this population. The purpose of this study was to examine hospitalized CHF patients and their nurses' perceptions regarding the importance and realism of typical patient education content. An instrument to assess learning needs was developed and piloted for use in this study. Thirty hospitalized patients and 26 nurses were surveyed. Both nurses and patients rated all information as important to learn and realistic to learn during the patients' hospitalizations. Patients and nurses agreed that medication information was the most important to learn. Generally, patients rated information as more important than nurses rated the same information areas. Suggested nursing interventions and future research endeavours are addressed.  相似文献

Objective:

To provide certified athletic trainers, team physicians, emergency responders, and other health care professionals with recommendations on how to best manage a catastrophic cervical spine injury in the athlete.

Background:

The relative incidence of catastrophic cervical spine injury in sports is low compared with other injuries. However, cervical spine injuries necessitate delicate and precise management, often involving the combined efforts of a variety of health care providers. The outcome of a catastrophic cervical spine injury depends on the efficiency of this management process and the timeliness of transfer to a controlled environment for diagnosis and treatment.

Recommendations:

Recommendations are based on current evidence pertaining to prevention strategies to reduce the incidence of cervical spine injuries in sport; emergency planning and preparation to increase management efficiency; maintaining or creating neutral alignment in the cervical spine; accessing and maintaining the airway; stabilizing and transferring the athlete with a suspected cervical spine injury; managing the athlete participating in an equipment-laden sport, such as football, hockey, or lacrosse; and considerations in the emergency department.  相似文献

Extrapersonal neglect is one clinical manifestation that can occur following stroke. Existing neglect assessment procedures have been criticised for lengthy administration and do not assess how extrapersonal space is affected. This study investigated the psychometric properties of a new, time-efficient screening tool for extrapersonal neglect. Full ethical approval was granted and consent obtained from 50 participants with first-time stroke. Participants were screened for extrapersonal neglect on two consecutive days by two raters using the Dublin Extrapersonal Neglect Assessment (DENA) to test inter-rater reliability. Construct validity of the DENA was investigated by comparing the DENA to the Catherine Bergego Scale (CBS). Additional analyses were calculated between the DENA and the extrapersonal items of the CBS (CBS-E). The kappa statistic, intraclass correlation coefficients (ICCs) and Bland Altman analyses were calculated to determine excellent inter-rater reliability (ICC 0.971, κ?=?.876) and significant correlation between the DENA and the CBS and CBS-E (ICC 0.870, 0.934, κ?=?.793, .833, respectively). Bland Altman analyses demonstrated acceptable levels of agreement between the DENA raters, and the DENA and CBS, with no systematic differences evident. The DENA provides clinicians with a quick and psychometrically sound screening tool for extrapersonal neglect to ensure this impairment is addressed in stroke rehabilitation.  相似文献
