Can a culture of team psychological safety and MDT proforma improve team performance and patient outcomes in spinal MDTs?

PURPOSE: Spinal multidisciplinary teams (MDTs) are now standard of care for complex patient management in tertiary spinal units. This study investigates whether a scheduling proforma, and cultural change to the team that promotes psychological safety, can improve spinal MDT effectiveness for team members and patients. METHODS: Retrospective cohort study including 165 spinal MDT patients before and after intervention. The intervention was use of a scheduling proforma and team learning to promote a culture of psychological safety. Data on accident and emergency (A&E) attendances, unplanned emergency admissions and post-operative 30-day readmissions were collected. At the team level, data were collected from 16 MDT participants using the MDT Observational Assessment Rating Scale (MDT-OARS), which measures MDT effectiveness. RESULTS: Pre-intervention MDT-OARS was 28. Analysis of 80 patients demonstrated there were six A&E attendances, three unplanned emergency admissions and four post-operative 30-day re-admissions. Post-intervention MDT-OARS was 38 (p < 0.05). Analysis of 85 patients demonstrated there were three A&E attendances, one unplanned emergency admission and one post-operative re-admission. CONCLUSIONS: Team culture that promotes psychological safety, along with use of a scheduling proforma, can improve MDT effectiveness for participants in spinal MDTs.

A Hemodynamic Safety Checklist Can Improve Blood Pressure Monitoring in Patients with Acute Spinal Cord Injury.

OBJECTIVE: The American Association and Congress of Neurological Surgeons recommended mean arterial blood pressure (MAP) in patients with acute spinal cord injury (SCI) should be 85-90 mm Hg for the first 7 days. We evaluated whether hemodynamic management differed between a primary-receiving and tertiary hospital in the first 24 hours for patients with acute SCI and assessed whether use of a checklist could improve hemodynamic management. METHODS: Observational review was performed of 79 patients with acute SCI before and after introduction of a blood pressure monitoring checklist and staff educational program designed to improve tertiary center management. Hemodynamic management in the primary-receiving hospital was compared with the tertiary center before and after checklist introduction. RESULTS: At the primary-receiving center, mean number of documented MAP readings/hour was 2.2 and 3 before and after checklist introduction. The proportion having >50% of MAP recordings <80 mm Hg was 26% and 22%. The proportion having >50% of MAP recordings <70 mm Hg was 8.5% and 7%. At the tertiary center, mean number of MAP readings/hour was 1.3 and 2.7 before and after checklist introduction (P = 0.02). The proportion having >50% of MAP recordings <80 mm Hg decreased from 36.5% to 16% after checklist introduction (P = 0.05). The proportion having >50% of MAP recordings <70 mm Hg decreased from 9% to 5.5% (P = 0.6). Polytrauma, inotrope use, and head injury significantly correlated with low MAP recordings (P < 0.05). Polytrauma was an independent risk predictor for low MAP recordings (P < 0.05). CONCLUSIONS: Achieving MAP targets for patients with acute SCI is challenging. Checklist use and staff education were associated with improved hemodynamic management. Presence of polytrauma identified patients at particular risk.

Results of Early and Late Surgical Decompression and Stabilization for Acute Traumatic Cervical Spinal Cord Injury in Patients with Concomitant Chest Injuries.

BACKGROUND: The benefits of early surgical decompression and stabilisation (within 24 hours of injury) for patients with acute traumatic spinal cord injury (SCI) is unclear. The study objective was to investigate the effects of early (<24 hours of injury) versus late (>24 hours of injury) decompressive and stabilisation surgery for traumatic cervical SCI in patients with concomitant chest injuries. METHODS: This was a retrospective study including adults aged 16 years or over with traumatic cervical SCI, Glasgow Coma Scale score >13, and concomitant chest injuries (e.g. hemopneumothoraces, flail chest and pulmonary contusions) necessitating intensive care unit (ICU) admission. Forty patients who met the inclusion criteria and underwent decompressive surgery within 24 hours were compared with 55 patients who underwent decompressive surgery after 24 hours. Primary outcomes were ordinal change in the ASIA Impairment Scale (AIS) at 6 months and duration of ICU stay. Secondary outcomes included complications occurring within 30 days. RESULTS: In the early surgery group, 21 patients (52.5%) showed no improvement in ASIA grade, 13 (32.5%) had a 1-grade improvement, and 6 (15%) had a 2-grade improvement. The median length of ICU stay was 14 days (range, 2-68). 42.5% of patients developed a complication and 45% required a tracheostomy. In the late surgery group, AIS grade improvement was as follows: 32 (58%) no improvement, 19 (34.5%) had a 1 grade improvement, 3 (5.5%) had a 2 grade improvement and 1 (2%) had a 3 grade improvement. Mean ICU stay was 23 days (4-68). 53% of patients developed a complication and 55% required a tracheostomy. There was one mortality in the late surgery group. CONCLUSIONS: For patients with acute traumatic cervical SCI and concomitant chest trauma, early surgical decompression and stabilisation was associated with reduced ICU stay and a lower complication rate. Neurological recovery was more likely in younger patients and those with an incomplete SCI.

Imaging findings of flexion type of hangman's fracture; an attempt for a more objective evaluation with newly introduced scoring system.

OBJECTIVE: To identify the flexion type of hangman's fracture on imaging studies. METHODS: 38 cases of hangman's fracture were retrospectively studied and categorized into flexion and non-flexion groups. Plain radiograph, CT and MRI of these patients were evaluated; 13 radiological parameters that might define flexion injuries were measured. The data were statistically analyzed to identify good criteria and to rank them according to their importance in predicting flexion. RESULTS: Seven radiological criteria that have the highest correlation with flexion injury were identified. These are C2-3 lower end-plate angle, C2-3 posterior body angle, interspinous angle, disc disruption (MRI), widening of interspinous distance, disruption of the posterior ligamentous complex (MRI) and angle at the fracture site. Scoring 1 point for each positive criterion, a total score of 4 predicts flexion injury with 100% sensitivity and 96.9% specificity. Score of 5 has 83.3% sensitivity and 100% specificity. CONCLUSION: Flexion hangman's injury can be diagnosed by the presence of four out of seven radiological criteria in the newly introduced scoring system. The authors believe that this method may help spinal surgeons in their selection of therapeutic strategy. Advances in knowledge: This study introduces fast, simple and more objective imaging criteria for the diagnosis of flexion hangman's injury and separates it from the non-flexion pattern.

Dermatofibrosarcoma Protuberans: Insights into a Rare Soft Tissue Tumor.

Dermatofibrosarcoma protuberans (DFSP) is a rare soft tumor which originally represents a cutaneous sarcoma. It grows slowly and presents usually as nodular superficial lesion on the trunk or the extremities. Although these tumors are locally aggressive with high rate of recurrence following surgery; the prognosis is considered excellent when it is effectively treated. The radiological appearance of this tumor has rarely been studied and findings infrequently discussed in the literature probably because many lesions underwent resection before imaging. Although imaging is infrequently performed for this lesion; it can show characteristic features and demonstrate the full extent. Imaging may also play a role in the differentiation of this tumor from more serious soft tissue lesions such as more aggressive sarcomas and hemangioma. In this article, we discuss the imaging findings of DFSP that can aid in its diagnosis and its variable appearances. In addition; the clinical presentation and treatment options are also described with review of the previous literature.

Missed acute appendicitis presenting as necrotising fasciitis of the thigh.

Necrotising fasciitis is a rapidly progressive soft tissue infection that leads to diffuse tissue necrosis. It is associated with systemic toxicity and rapid deterioration resulting in high mortality. Rapid diagnosis and prompt treatment are essential to improve the outcome. We report the case of a 26-year-old woman who presented with severe thigh pain and swelling associated with irritability of a few hours' duration following 2 days history of right abdominal pain. Urgent MRI and CT scan showed features of necrotising fasciitis in the thigh spreading from an inflamed appendix. Emergency surgery was performed which revealed perforated appendix with disseminated infection in the intraperitoneal and retroperitoneal spaces as well as the right thigh. The patient rapidly deteriorated with evidence of sepsis, shock and renal impairment. In spite of surgery and all supportive measures, she succumbed shortly postoperatively. Blood culture revealed Staphylococcus aureus and Streptococci, while tissue culture showed growth of Escherichia coli and proteus.

Iliac artery pseudoaneurysm presenting as a paravertebral collection: a potentially fatal mimic.

Pseudoaneurysms of the iliac arteries are extremely rare and can complicate trauma, surgical or interventional procedures. We report a case of pseudoaneurysm arising from the common iliac artery in a 37-year-old man which presented as a paravertebral collection. As the MRI appearance mimicked spondylodiscitis, a CT guided biopsy was requested. However, the presence of a signal void centre guided the radiologist to the correct diagnosis, which was later confirmed on contrast-enhanced CT. Following unsuccessful treatment by percutaneous thrombin injection, open surgery was performed which revealed a leaking aneurysm associated with a huge retroperitoneal haematoma. We present this case to highlight the importance of considering vascular lesions as a differential diagnosis in patients presenting with a mass or pressure symptoms in different parts of the body. Misdiagnosing such lesions as soft tissue tumours or abscesses may result in serious consequences.
