Credibility, readability and content analysis of treatment recommendations for adolescents with nonspecific back pain published on consumer websites.

BACKGROUND: Parents may seek out health information online when their adolescent has nonspecific back pain to better understand treatment options. Such information directed towards consumers has not been previously analysed. METHODS: A descriptive cross-sectional content analysis was performed to describe the treatments recommended on consumer websites for nonspecific back pain in adolescents. The credibility and readability of the websites were also assessed. Systematic Google searches were completed in five countries, and relevant content from eligible web pages was analysed. An a priori codebook with 34 treatment-related codes was developed. Nine additional codes were inductively created during analysis. Credibility was assessed using the JAMA benchmark. Readability was assessed via the Flesch Kincaid Grade Level. RESULTS: Of 245 web pages, 48 were deemed eligible and analysed. Of 43 treatment codes, 37 were present in at least one web page. The five most frequently identified codes were See the doctor/get a diagnosis (found on 85% of web pages), Ergonomics/posture/biomechanics (52%), Reassurance (48%), Physiotherapy (48%) and Non-prescription pharmaceuticals/supplements (46%). Only 21% of the web pages met all four JAMA benchmark criteria, and 15% cited at least one recent or high-quality source. The median Flesch Kincaid Grade Level score was 9.0 (range 3.5-12.9). CONCLUSIONS: Parents of adolescents with nonspecific back pain may find that treatment recommendations published online are numerous and varied, with visits to the doctor encouraged. The credibility scores of these web pages are generally low, while the median reading level may be too high for the general population. SIGNIFICANCE STATEMENT: This analysis reveals that public-facing websites with recommendations for treating adolescent nonspecific back pain do not cite the most recent, high-quality research. Although web pages correctly encourage physical activity and exercise over surgery and prescription medications, they do not reflect the psychologically informed or interdisciplinary care emphasized in recently published treatment recommendations. Clinicians must be aware that caregivers of their adolescent patients with nonspecific back pain may be exposed to online messages that encourage them to keep seeking a diagnosis.

An evaluation of a one-day pain science education event in a high school setting targeting pain related beliefs, knowledge, and behavioural intentions.

BACKGROUND: Persistent pain is a common condition affecting one in four UK adults. Public understanding of pain is limited. Delivering pain education within schools may improve public understanding in the longer term. OBJECTIVE: To evaluate the impact of a one-day Pain Science Education (PSE) event on sixth form/high school students' pain beliefs, knowledge and behavioural intention. METHODS: Exploratory, single-site, mixed-methods, single-arm study involving secondary school students ≥16 years old attending a one-day PSE event. Outcome measures included the Pain Beliefs Questionnaire (PBQ), Concepts of Pain Inventory (COPI-ADULT), a vignette to assess pain behaviours; and thematic analysis of semi-structured interviews. RESULTS: Ninety (mean age 16.5 years, 74% female) of the 114 attendees, agreed to participate in the evaluation. PBQ scores improved on the Organic beliefs subscale [mean difference -5.9 (95% CI -6.8, -5.0), P < 0.01] and Psychosocial Beliefs subscale [1.6 (1.0, 2.2) P < 0.01]. The COPI-Adult revealed an improvement [7.1 (6.0-8.1) points, P < 0.01] between baseline and post intervention. Pain behavioural intentions improved post education for work, exercise, and bed rest related activities (p < 0.05). Thematic analysis of interviews (n = 3) identified increased awareness of chronic pain and its underpinning biology, beliefs that pain education should be widely available, and that pain management should be holistic. CONCLUSIONS: A one-day PSE public health event can improve pain beliefs, knowledge and behavioural intentions in high school students and increase openness to holistic management. Future controlled studies are needed to confirm these results and investigate potential long-term impacts.

Minimal aortic injury: a lesion associated with advancing diagnostic techniques.

BACKGROUND: With the increasing use of high-resolution diagnostic techniques, minimal aortic injuries (MAI) are being recognized more frequently. Recently, we have used nonoperative therapy as definitive treatment for patients with MAI. The current study examines our institutional experience with these patients from July 1994 to June 2000. METHODS: All patients suspected of blunt aortic injury (BAI) by screening helical CT (HCT) underwent confirmatory aortography with or without intravascular ultrasound (IVUS). MAI was defined as a small (<1 cm) intimal flap with minimal to no periaortic hematoma. RESULTS: Of the 15,000 patients evaluated by screening HCT, 198 (1.3%) were suspected of having BAI. BAI was confirmed in 87 (44%), and 9 (10%) of these had MAI. The initial aortogram was considered normal in five of the MAI patients. The correct diagnosis was made by IVUS (four patients), and video angiography (one patient). One MAI patient had surgery, and two (22%) died of causes not related to the aortic injury. Follow-up studies were done on the six MAI patients that were discharged. In two, the flap had completely resolved, and in one it remained stable. The remaining three patients formed small pseudoaneurysms. CONCLUSION: Ten percent of BAI diagnosed with high resolution techniques have MAI. These intimal injuries heal spontaneously and hence may be managed nonoperatively. However, the long-term natural history of these injuries is not known, and hence caution should be exercised in using this form of treatment.

Traumatic rupture of the aortic isthmus: program of selective management.

Two hypotheses were investigated: (1) helical computed tomography (CT) of the chest on victims of decelerating trauma can yield a diagnosis of, or "rule out," a traumatic rupture of the aorta (TRA) without the need for an aortogram; and (2) selective delay of aortic repair can be safely accomplished through a medical management protocol. Screening helical CT examinations were done on 6169 victims of blunt thoracic trauma; 47 were found to have TRA; in 8, indirect but nondiagnostic findings not clarified by an aortogram led to surgical exploration. The sensitivity of helical CT was higher than that of aortograms, and a "normal" helical CT scan was never associated with a proved TRA. It is estimated that the use of helical CT has resulted in at least a 40% to 50% decrease in the need for aortograms, in addition to yielding rapid, noninvasive valuable information about other injuries. Drugs (beta-blockers +/- vasodilators) to decrease the stress in the aortic wall were used in 93 patients when the diagnosis was suspected and were continued as necessary through the evaluation, stabilization, and until the aorta was cross-clamped at operation. Elective, delayed operation was done between 2 days and 25 months in 15 patients who were deemed to be excessive risks for emergency aortic repair; there were 2 deaths (13. 3%). Eleven patients never had aortic repair. No patient maintained on this protocol, whether repaired emergently, electively, or not at all, developed free rupture of the periaortic hematoma and death from TRA.

Prospective study of blunt aortic injury: helical CT is diagnostic and antihypertensive therapy reduces rupture.

OBJECTIVE: There were two aims of this study. The first was to evaluate the application of helical computed tomography of the thorax (HCTT) for the diagnosis of blunt aortic injury (BAI). The second was to evaluate the efficacy of beta-blockers with or without nitroprusside in preventing aortic rupture. SUMMARY BACKGROUND DATA: Aortography has been the standard for diagnosing BAI for the past 4 decades. Conventional chest CT has not proven to be of significant value. Helical CT scanning is faster and has higher resolution than conventional CT. Retrospective studies have suggested the efficacy of antihypertensives in preventing aortic rupture. METHODS: A prospective study comparing HCTT to aortography in the diagnosis of BAI was performed. A protocol of beta-blockers with or without nitroprusside was also examined for efficacy in preventing rupture before aortic repair and in allowing delayed repair in patients with significant associated injuries. RESULTS: Over a period of 4 years, 494 patients were studied. BAI was diagnosed in 71 patients. Sensitivity was 100% for HCTT versus 92% for aortography. Specificity was 83% for HCTT versus 99% for aortography. Accuracy was 86% for HCTT versus 97% for aortography. Positive predictive value was 50% for HCTT versus 97% for aortography. Negative predictive value was 100% for HCTT versus 97% for aortography. No patient had spontaneous rupture in this study. CONCLUSIONS: HCTT is sensitive for diagnosing intimal injuries and pseudoaneurysms. Patients without direct HCTT evidence of BAI require no further evaluation. Aortography can be reserved for indeterminate HCTT scans. Early diagnosis with HCTT and presumptive treatment with the antihypertensive regimen eliminated in-hospital aortic rupture.

Blunt injuries of the brachiocephalic artery.

Blunt injury of the brachiocephalic artery can pose diagnostic and management problems for the trauma and thoracic surgeon. To arrive at recommendations for dealing with this injury, we reviewed a seven-year experience at our trauma center. Between 1988 and 1995, five patients presented with blunt injuries of the brachiocephalic artery. All patients were stabilized and underwent repair through a median sternotomy with extension of the incision anterior to the sternocleidomastoid muscle. All patients had restoration of flow to the subclavian and carotid arteries utilizing bypass grafts (4) or primary repair (1). All patients survived to leave the hospital with no complications related to the procedure. Postoperative neurologic findings were present before the operative repair. Patients with blunt injuries of the brachiocephalic artery should be stabilized, and circulation of the subclavian and carotid arteries should be restored with graft placement or primary repair. Cardiopulmonary bypass and heparin or temporary shunts were not needed in this series of patients. Complications were related to associated injuries.

Subclavian artery injuries.

Thirty-two consecutive patients with subclavian artery injuries were evaluated to assess the mechanism of injury, types of repair, and results. In this series, most wounds were from firearms. Although the mortality was high (19%), most patients had the vessel repaired successfully. Associated injuries, especially to neural structures, led to significant morbidity. Principles used in dealing with these injuries should be 1) proximal and distal control prior to exposing the injury site, 2) reestablishing distal circulation through primary repair or graft placement, and 3) identifying and treating associated injuries.

Function of "nontrauma" surgeons in level I trauma centers in the United States.

Although the general "trauma" surgeon is usually the team leader in level I trauma centers, the use of surgical subspecialists and nonsurgeons is frequently ill-defined. This study was done to gain data in regard to actual use of subspecialists in busy centers. First, a survey of the patterns of staffing in 140 trauma centers was elicited by mail questionnaire, supplemented by telephone cells. Second, records of 400 consecutive patients at the Elvis Presley Trauma Center were reviewed to determine the use of subspecialists during the first 24 hours of care of individual patients. There were differences in the use of surgical subspecialists and nonsurgeons at different centers: in receiving, admitting, operating, and critical care areas and in privileges for admission and attending of inpatients. Consultation "guidelines" are used for many specific injuries. At our center, a mean of 1.92 subspecialists, in addition to general surgeons, were involved in the early care of each patient. Problems exist in many centers regarding the use of subspecialists, especially for management of facial and chest injuries. In some centers nonsurgeons function in the intensive care unit, and as admitting and attending physicians of trauma patients.

Perfluorocarbons: future clinical possibilities.

Perfluorocarbons are now being used as oxygen carriers in clinical settings. Because these chemicals may have a role as a blood substitute, in organ preservation, and in the management of respiratory failure, we have reviewed some of the research leading to these applications.

Combined gunshot injuries of the trachea and esophagus.

During an 8-year period between 1985 and 1993, twelve patients were treated with combined gunshot wounds to the trachea and esophagus. All patients survived, but there were complications, including one tracheoesophageal fistula. Combined injuries of the trachea and esophagus should be repaired primarily, and drains do not necessarily have to be placed. The benefit of a muscle flap placed between the repairs was not confirmed in this series. Complications should be recognized early and treated aggressively to minimize damage to the airway.

Is routine carotid screening for coronary surgery needed?

An association between carotid and coronary artery disease is well recognized. Routine preoperative duplex carotid screening of all coronary surgery patients is common, but may delay surgery and increase cost. To evaluate such a policy: A retrospective review of the records of 308 consecutive patients undergoing coronary surgery at one hospital was performed. Duplex studies were done on 210. A history of TIA/RIND, CVA, AS-PVD, AAA, neck bruit, or prior carotid surgery was considered suggestive for carotid disease. The history and/or physical exam (HPE) suggested carotid disease in 114; 37 of these (32%) had a positive scan. Of 96 patients without +HPE, three (3%) had a significant stenosis. A prospective study of cardiac surgery patients was done, categorized into "carotid" (n = 33) or "no-carotid" (n = 50) disease by two independent observers, based on +HPE. Positive scans were found in 27 per cent of the "carotid disease" group; No positive scans were found in the "no-carotid disease" group. We conclude that coronary surgery patients with peripheral or cerebral vascular disease or a neck bruit should have preoperative carotid studies. Duplex carotid screening of all cardiac patients is neither medically efficient nor cost-effective.

Coronary operations in patients with spinal cord injury.

BACKGROUND: The risk of heart disease in patients with spinal cord injury is similar to that in the general population. The physiologic derangements raise special problems in patients with SCI having coronary operations. METHODS: From January 1980 to May 1995, we performed coronary artery bypass procedures on 20 patients with SCI; 4 were tetraplegic and the remainder were paraplegic. The indication for operation was angina: unstable (13), exertional (4), or postinfarctional (3). Bowel and bladder care was given immediately before operation; operating room tables were double padded and a pelvic wrap was used to protect the back. Electric wheelchairs were used for early mobilization. RESULTS: Vasomotor instability from cardiopulmonary bypass was not present in patients with SCI. Pharmacologic support was required in the operating room by 4 patients for low vascular resistance, but in only one case in the intensive care unit. One patient required ventilation support for more than 24 hours. All patients were able to cough effectively. No thoracic wound complications occurred. There were three operative deaths, all in patients with multiple risk factors. The acute hospital stay averaged 9.3 days; patients were then transferred to an SCI unit for rehabilitation, were upper-extremity weight bearing was restricted for 2 to 4 weeks. CONCLUSIONS: Patients should not be denied coronary artery bypass procedures because of an SCI, but their special needs must be managed properly.

Combined tracheal and esophageal trauma from gunshot wounds.

During a 5-year period between 1988 and 1993, nine patients with combined tracheal and esophageal injuries were treated at our institution. All injuries resulted from gunshot wounds and all were repaired. All patients survived, but complications included one tracheoesophageal fistula. Combined injuries of the trachea and esophagus should be repaired primarily, and drains do not necessarily have to be placed. The benefits of a muscle flap placed between the repairs were not confirmed in this series. Complications should be recognized early and treated aggressively to minimize damage to the airway.

Chest wall resection for Ewing's sarcoma of the rib: an unnecessary procedure. 1988. Updated in 1995.

Approximately 10% of all cases of Ewing's sarcoma arise from a rib. Conventional management has included chest wall resection (3 or more ribs) and radiation therapy. These forms of therapy have led to complications such as scoliosis and local deformity. The addition of radiation therapy can result in damage to the lung and adjacent viscera and also potentiate pulmonary restrictive disease. Between 1971 and 1978, 9 patients were treated with surgery, radiation therapy, and combination chemotherapy (three- or four-drug regimen). Only 2 patients (22%) survive. Since 1979, 14 patients were entered into a new protocol consisting of sequential induction chemotherapy, followed by delayed surgical resection whenever feasible. Three patients had complete resection of their primary lesion at onset. Initially, 7 patients had either biopsy (N = 4) or incomplete chest wall resection N = 3). All 4 patients with biopsy only at diagnosis had excellent responses to induction chemotherapy, allowing delayed resection of the involved rib without chest wall resection. Overall, 12 of 14 patients (86%) treated since 1979 survive, with only 2 receiving radiation therapy for residual disease in the primary rib site.

Video-assisted thoracic surgery: primary therapy for spontaneous pneumothorax?

BACKGROUND: This study assessed the role of video-assisted thoracic surgery (VATS) in current therapy for spontaneous pneumothorax. METHODS: We compared a retrospective series of 89 patients treated conventionally with a consecutive group of 30 patients undergoing VATS pleural abrasion. The 89 earlier patients were predominantly male (81%). Treatment groups included observation/aspiration (7 or 17%), tube thoracostomy (32 or 36%), multiple tubes (7 or 9%), and thoracotomy (43 or 48%). Of the 30 patients treated with VATS, 18 (66%) were male. Primary indications for operation were recurrent pneumothorax (17) and persistent air leak (9). RESULTS: Hospital lengths of stay (LOS) for the earlier group were 5 days for simple tube and 7 days for primary thoracotomy; LOS for initial intervention followed by thoractomy exceeded 15 days in all subgroups. The average LOS in the VATS group was 13 days; 6 patients treated with primary VATS (no chest tube) had a mean LOS of 6.5 days. Complications included 3 (10%) prolonged air leaks (more than 7 days) and 2 (7%) early recurrences. CONCLUSIONS: We do not recommend VATS as primary therapy for spontaneous pneumothorax; tube thoracostomy remains the treatment of choice. However, we strongly support surgical intervention early (3 days) in patients with a persistent air leak, and as primary therapy in a nonurgent situation if standard indications exist. This study shows no advantage of VATS over conventional thoracotomy in hospital stay or complication rate.
