Safety Culture and Attitudes Among Spine Professionals: Results of an International Survey

Study Design: International survey. Objective: A positive safety culture has been linked to better surgical outcomes, less hospital costs and less patient harm and severity-adjusted mortality, making safety attitudes relevant for society and both patient and health care provider. The aim of the current study is to assess attitudes toward safety culture among spinal care professionals. Methods: An online survey was distributed to members of AOSpine International in 2016. The survey consisted out of 3 parts: (1) demographics, (2) the Safety Attitude Questionnaire (SAQ), and (3) expectations of responsibility for improving the safety culture. The SAQ measured job satisfaction, teamwork, and safety climate, perceptions of management, stress recognition, and working conditions. Multivariate logistic regression was performed to identify factors associated with safety attitudes. Results: A total of 356 respondents replied. The SAQ showed that respondents in Africa have a significant lower score (odds ratio [OR] 0.19, P .05). The majority expected the surgeon to be mainly responsible for improving the safety culture in the operating room and at management level. Conclusions: There was a lot of variety among different respondents worldwide albeit respondents in Africa scored significantly lower on working conditions, compared with spine professionals in Asia and North America, suggesting that wealthier countries have better working conditions which may lead toward better safety attitudes. Closer collaboration between hospital management and clinicians seems to be a target for improvement in safety culture. Furthermore, to show clinical relevance in this field, studies correlating safety attitudes with outcomes after spine surgery are warranted

The neurosurgical curriculum: Which procedures are essential?

Objective: Traditionally, neurosurgery is a competitive field. Throughout the years, the surgical armamentarium has been subject to change, e.g. due to the rise of indications for gamma knife, functional or endovascular surgery. Furthermore, due to modern day issues among residents, such as work hour restrictions (WHRs) and prevalence of burn-out, may require contemporary modifications of the neurosurgical curriculum. By the means of this cross sectional research, the current curriculum is evaluated. Methods: In September 2019, a 21-question survey was mailed to members of the Congress of Neurological Surgeons using SurveyMonkey. The survey consisted out of 3 parts: demographics of the respondents, respondent‘s neurosurgical residency and opinions on essential procedures. Results: After the two reminders, 578 members responded resulting in a response rate of 7.3%. Respondents had a mean residency program of 7 years (range 3 to 12 years). Of the residents, 87.5% had a weekly WHR of 80 h per week. A minority (43.8%) felt WHRs would limit the chances of residents to master surgical techniques. Neurotraumatical procedures such as decompression of subdural (91.5%) and epidural (91.3%) hematoma‘s, ventriculoperitoneal shunt insertion (86.9%), Chiari decompression (81.4%) and cervical discectomy (81.4%) were the procedures respondents mastered the most. This in contrast to endovascular procedures (67.9%), percutaneous endoscopic lumbar discectomy (48.5%) and deep brain stimulation (34%), in which respondents were less proficient. Conclusions: The current study gives an evaluation of different neurosurgical curricula and aimed to identify which surgical procedures are deemed as essential by neurosurgeons worldwide. Functiona

Practice variation in the conservative and surgical treatment of chronic subdural hematoma

Objective: Chronic subdural hematoma (CSDH) is a condition that is frequently seen in the neurological and neurosurgical practice. Surgical treatment is overall preferred; however, conservative treatment is also an option. Both surgical and conservative treatment of CSDH vary across neurosurgeons. The aim of the present study was to evaluate different treatment strategies for CSDH among neurosurgeons in different countries. Material and Methods: We designed a survey that was sent to neurosurgeons affiliated with the Congress of Neurological Surgeons.The questions were related to the conservative and surgical treatment methods of CSDH. Furthermore, we also included questions related to post-operative care. Results: 443 neurosurgeons completed the survey. 46.2 % of the respondents sometimes use dexamethasone as monotherapy. Overall, 26.2 % estimated dexamethasone to have a high efficacy on CSDH. A Glas

Anterior cervical discectomy without fusion for a symptomatic cervical disk herniation

Background: Cervical radiculopathy is characterized by dysfunction of the nerve root usually caused by a cervical disk herniation. The most important symptom is pain, radiating from the neck to the arm. When conservative treatment fails, surgical treatment is indicated to relieve symptoms. During the last decades, multiple fusion techniques have been developed, although without clinical evidence for added value of fusion over non-fusion. Methods: The surgical procedure of anterior cervical discectomy without fusion is performed step by step, leading to removal of the entire intervertebral disk. Conclusion: Anterior cervical discectomy without fusion is a safe and effective treatment for cervical disk herniation

Long-Term Clinical Results of Percutaneous Cervical Nucleoplasty for Cervical Radicular Pain:A Retrospective Cohort Study

PURPOSE: Percutaneous cervical nucleoplasty (PCN) is a minimally invasive treatment for cervical radicular pain due to a disc herniation. Preliminary results show equivalent patient-reported outcomes of PCN as compared to conventional anterior cervical discectomy. However, there is a paucity of long-term outcome data. Therefore, the primary objective of this study is to investigate the long-term clinical results of PCN. PATIENTS AND METHODS: A retrospective analysis was conducted on patients who underwent PCN at a secondary referral center between 2010 and 2014. Before surgery and five days after surgery, numeric rating scales (NRS) for arm pain and neck pain and data on complications were collected. To determine long-term follow-up outcomes, patients were sent a questionnaire booklet containing the Core Outcome Measures Index-Neck (COMI-Neck), NRS for arm pain and neck pain, Likert-scales on patient satisfaction and questions regarding the incidence of reoperations and complications. RESULTS: The baseline characteristics were collected for 158 patients. At a median follow-up of 41.5 months (interquartile range (IQR) 27.0 to 57.5), data were available for 118 patients (74.7%). At short-term follow-up, patients that underwent PCN had a mean decrease of 3.0 on the NRS for arm pain (95% CI 2.5 to 3.6) compared to baseline, while at long-term follow-up, a mean decrease of 2.8 (95% CI 1.0 to 3.6) was observed. At the long-term follow-up, 67.8% of the patients were fully recovered from all symptoms and 93.3% remained satisfied with the PCN treatment results. The reoperation rate for recurrent disc herniation was 21.4% at long-term follow-up. CONCLUSION: PCN appears to be a safe and effective treatment at short-term and long-term follow-up of a specific selection of cervical herniated discs, with an acceptable long-term reoperation rate. These study results suggest a potential role of PCN as a less invasive treatment option for cervical radicular pain due to a soft disc herniation, before anterior cervical discectomy should be considered

Outcome of non-instrumented lumbar spinal surgery in obese patients: a systematic review

Introduction: Lumbar spinal decompression procedures are well known in their techniques and outcomes. However, outcomes of lumbar spinal surgery in patients with obesity are relatively unknown. The aim of this review is to assess the effect of obesity on post-operative outcomes of lumbar non-instrumented decompressive spinal surgery. Methods and materials: A literature search through PubMed, Embase, Web of Science and Cochrane was performed. Articles were included if they reported outcomes of obese patients after non-instrumented lumbar decompression surgery, if these outcomes were described using patient-reported outcome measures and if there was at least two months of follow-up. Risk of bias was assessed using an adjusted version of the Cowley score. Results: From the 222 unique articles, 14 articles, comprising 13,653 patients, met the inclusion criteria. Eight out of 14 studies had a low risk of bias, while the remaining six had an intermediate risk of bias. Thirteen studies evaluated leg and back pain, and the vast majority demonstrated less decrease in pain in the obese group. Six studies evaluated disability and all but one showed less improvement in obese patients. Five studies evaluated functionality and wellbeing and all but one showed less satisfactory outcome in obese patients. Conclusions: Literature does not reveal a difference in clinical outcome nor in complications in patients undergoing non-instrumented lumbar surgery with a BMI lower than 30 or equal to or higher than 30. This may be used by physicians to inform patients prior to lumbar decompression surgery

How I do it: percutaneous transforaminal endoscopic discectomy for lumbar disk herniation

Background: Percutaneous transforaminal endoscopic discectomy (PTED) has emerged as a less invasive technique to treat symptomatic lumbar disk herniation (LDH). PTED is performed under local anesthesia with the advantage of immediate intraoperative feedback of the patient. In this paper, the technique is described as conducted in our hospital. Methods: PTED is performed under local anesthesia in prone position on thoracopelvic supports. The procedure is explained stepwise: e.g. marking, incision, introduction of the 18-gauge needle and guidewire to the superior articular process, introduction of the TomShidi needle and foraminotomy up to 9 mm, with subsequently removal of di

Mistreatment, discrimination and burn-out in Neurosurgery

Objective: Issues concerning harassment, bullying and discrimination are not unknown to medical specialties and are likely to be present in neurosurgery as well. The aim of this study was to estimate the extent to which neurosurgeons are faced with issues pertaining to this mistreatment. Methods: A survey consisting of fourteen questions was distributed among members of the Congress of Neurological Surgeons (CNS). The survey consisted of three parts: 1) demographics; 2) exposure to mistreatment; 3) experienced burnout symptoms. Results: In total 503 out of the 5665 approached CNS members filled in a survey (response rate 8.9 %). Respondents consisted for 85.9 % out of neurosurgeons and for 13.9 % out of residents. Overall, 61.4 % of the respondents was a victim of form of abusive behavior, while 47.9 % was a victim of at least one form of discrimination. Most reported sources of these mistreatments were other neurosurgeons or (family of) patients. Overall, 49.9 % of the respondents experienced burnout symptoms. Multivariable logistic regression analysis showed that female respondents had higher odds of being a victim of abuse (OR 2.5, 95 % CI 1.4–4.6). Female respondents (OR 19.8, 95 % CI 8.9–43.9) and ethnic minorities (OR 3.8, 95 % CI 2.3–6.2) had higher odds of being a victim of discrimination. Furthermore, victims of abuse were at higher odds (OR 1.7, 95 % CI 1.1–2.6) of having burnout symptoms. Conclusions: Mistreatment and experiencing burnout symptoms frequently occurs among neurosurgeons and residents
