Surgeon clinical practice variation and patient preferences during the informed consent discussion: a mixed-methods analysis in lumbar spine surgery.

Background: Patients with lumbar disc herniation may greatly benefit from microdiscectomy. Although spine surgeons performing microdiscectomy routinely obtain informed consent, the potential adverse events they disclose often vary. Moreover, little is known about what disclosures are deemed most valuable by patients. The aim of this mixed-methods study was to determine practice variations among spine surgeons in regard to the disclosure of potential adverse events during informed consent discussions for lumbar microdiscectomy and to determine which topics patients perceived to be valuable in the consent discussion. Methods: A survey evaluating the frequency with which spine surgeons disclose 15 potential adverse events related to lumbar microdiscectomy during informed consent discussions was distributed among Canadian Spine Society members. Additionally, semistructured interviews were conducted with preoperative patients, postoperative patients, attending spine surgeons, spine fellows and orthopedic residents. Interview transcripts were analyzed using thematic analysis with open coding. Results: Fifty-one Canadian Spine Society members completed the survey. The number of potential adverse events not routinely discussed was greater among orthopedic surgeons than among neurosurgeons (relative risk 1.83; 95% confidence interval 1.22-2.73; p = 0.003). Three preoperative patients, 7 postoperative patients, 6 attending spine surgeons, 3 spine fellows and 5 orthopedic residents participated in the semistructured interviews. The interviews identified gaps in information provided to patients, particularly on topics relating to postoperative care such as expected recovery time, activity restrictions and need for a caregiver. Conclusion: There is variation in the disclosure of potential adverse events during informed consent discussions for lumbar microdiscectomy among Canadian spine surgeons. Patients desire more information regarding their postoperative care. Further research should focus on developing guidelines to reduce practice variation and optimize the effectiveness of consent discussions.

Contexte: Les patients atteints d'une hernie discale lombaire pourraient profiter grandement d'une microdiscectomie. Bien que les chirurgiens spécialistes de la colonne vertébrale réalisant des microdiscectomies obtiennent toujours le consentement éclairé du patient, les événements indésirables potentiels présentés varient souvent. De plus, on en connaît peu sur les informations les plus importantes du point de vue des patients. L'objectif de cette étude à méthodes mixtes était de déterminer les différentes pratiques des chirurgiens en ce qui a trait à la présentation des événements indésirables potentiels pendant les discussions sur le consentement éclairé pour les microdiscectomies lombaires et de déterminer les sujets les plus importants pour les patients pendant ces discussions. Méthodes: Un sondage sur la fréquence à laquelle les chirurgiens présentent 15 événements indésirables potentiels associés à la microdiscectomie lombaire pendant les discussions sur le consentement éclairé a été distribué aux membres de la Société canadienne du rachis. De plus, des entretiens semi-dirigés ont été réalisés auprès de patients en période préopératoire, de patients en période postopératoire, de chirurgiens spécialistes de la colonne vertébrale, de fellows en chirurgie spinale et de résidents en chirurgie orthopédique. Des analyses thématiques utilisant un code ouvert ont été réalisées sur les transcriptions des entretiens. Résultats: Cinquante-et-un membres de la Société canadienne du rachis ont répondu au sondage. Le nombre d'événements indésirables potentiels non systématiquement mentionnés était plus élevé chez les chirurgiens orthopédiques que chez les neurochirurgiens (risque relatif 1,83; intervalle de confiance de 95 % 1,22­2,73; p = 0,003). Dans les entretiens semi-dirigés, on a recueilli les commentaires de 3 patients en période préopératoire, de 7 patients en période postopératoire, de 6 chirurgiens spécialistes de la colonne vertébrale, de 3 fellows en chirurgie spinale et de 5 résidents en chirurgie orthopédique. Les entretiens ont révélé des lacunes dans l'information transmise aux patients, particulièrement sur les soins postopératoires, comme le temps de récupération attendu, les restrictions quant aux activités et la nécessité d'un soignant. Conclusion: On a trouvé une variation dans la présentation des événements indésirables potentiels pendant les discussions sur le consentement éclairé pour les microdiscectomies lombaires chez les chirurgiens spécialistes de la colonne vertébrale au Canada. Les patients veulent en savoir plus sur les soins postopératoires. Des lignes directrices devraient être établies pour réduire les différences entre les pratiques et optimiser l'efficacité des discussions sur le consentement.

Quality of life and educational benefit among orthopedic surgery residents: a prospective, multicentre comparison of the night float and the standard call systems.

BACKGROUND: Given recent evolving guidelines regarding postcall clinical relief of residents and emphasis on quality of life, novel strategies are required for implementing call schedules. The night float system has been used by some institutions as a strategy to decrease the burden of call on resident quality of life in level-1 trauma centres. The purpose of this study was to determine whether there are differences in quality of life, work-related stressors and educational experience between orthopedic surgery residents in the night float and standard call systems at 2 level-1 trauma centres. METHODS: We conducted a prospective cohort study at 2 level-1 trauma hospitals comprising a standard call (1 night in 4) group and a night float (5 14-hour shifts [5 pm-7 am] from Monday to Friday) group for each hospital. Over the course of a 6-month rotation, each resident completed 3 weeks of night float. The remainder of the time on the trauma service consists of clinical duties from 6:30 am to 5:30 pm on a daily basis and intermittent coverage of weekend call only. Residents completed the Short Form-36 (SF-36) general quality-of-life questionnaire, as well as questionnaires on stress level and educational experience before the rotation (baseline) and at 2, 4 and 6 months. We performed an analysis of covariance to compare between-group differences using the baseline scores as covariates and Wilcoxon signed-rank tests (nonparametric) to determine if the residents' SF-36 scores were different from the age- and sex-matched Canadian norms. We analyzed predictors of resident quality of life using multivariable mixed models. RESULTS: Seven residents were in the standard call group and 9 in the night float group, for a total of 16 residents (all men, mean age 35.1 yr). Controlling for between-group differences at baseline, residents on the night float rotation had significantly lower role physical, bodily pain, social function and physical component scale scores over the 6-month observation period. Compared with the Canadian normative population, the night float group had significantly lower SF-36 scores in all subscales except for bodily pain. There were no differences noted between the standard call group and Canadian norms at 6 months. No differences in educational benefits and stress level were measured between the 2 groups. Lack of time for physical activity was only significant in the night float group. Regression analysis demonstrated that the increased number of hours in hospital correlated with significantly lower SF-36 scores in almost all domains. CONCLUSION: Our study suggests that the residents in the standard call group had better health-related quality of life compared with those in the night float group. No differences existed in subjective educational benefits and stress level between the groups.

Clinical accuracy of computer-assisted two-dimensional fluoroscopy for the percutaneous placement of lumbosacral pedicle screws.

STUDY DESIGN: Clinical case series. OBJECTIVE: The primary objective of this study was to evaluate the clinical accuracy of computer-assisted two-dimensional fluoroscopy (2D-CAS) for the percutaneous placement of lumbosacral pedicle screws. SUMMARY OF BACKGROUND DATA: Loss of visual anatomic landmarks and reduced tactile feedback increases the risk of pedicle screw misplacement by when using minimally invasive (MIS) percutaneous techniques. However, objective data on screw misplacement in this scenario is lacking. METHODS: A MIS-2D-CAS technique (FluoroNav) was used for the placement of pedicle screws in 41 consecutive patients undergoing MIS-interbody instrumented fusion. Postoperative computerized tomography (CT) was obtained in all patients at 6 months after surgery and was evaluated by 3 observers. The relative position of the screw to the pedicle was graded regarding pedicle breach (I, no breach; II, <2 mm; III, 2-4 mm; IV, >4 mm), breach direction, vertebral body perforation and screw trajectory. Interobserver reliability of CT grading was assessed with kappa statistics. RESULTS: A total of 161 screws were placed. No neurologic, vascular, or visceral injuries occurred. About 37 (23%) screws breached the pedicle. The majority (83.8%, 31/37) of breaches were graded II. There were 5 Grade III and 1 Grade IV breaches. Medial versus lateral breaches occurred in 30% (11/37) and 60% (22/37), respectively; 10% (4/37) of the breaches were superior. Overall, 8 (5%) vertebral body breaches occurred. Of the pedicle screws, 19 (12%) had trajectories that deviated from acceptable, with the majority being medial (16/19, 84%). Fluoroscopy time for screw placement was typically less than 20 seconds total per case. There was 1 clinically significant breach at L5 (III, medial) which resulted in a L5 radiculopathy. Kappa statistics showed excellent overall agreement between reviewers (k = 0.73-0.92; 90%-96% agreement). CONCLUSION: The two-dimensional (2D) virtual fluoroscopy is a clinically acceptable option for percutaneous placement of pedicle screws. However, this technique requires cautious application and is particularly vulnerable to axial trajectory errors.

Our case report highlights the complexity of treating multi-ligament knee injuries in the setting of ipsilateral long bone trauma. We describe the use of the tibial inlay technique for PCL reconstruction in the setting of a tibial shaft fracture treated with an intramedullary nail. We also present a comprehensive treatment algorithm for the treatment of ligamentous knee injuries in the setting of long bone trauma.

Residents' quality of life during an orthopedic trauma rotation: a multicentre prospective observational study.

OBJECTIVE: Fewer orthopedic surgery trainees are choosing careers in trauma. The impact of stressors on health-related quality of life has not been evaluated among orthopedic surgical residents. The current study aimed to determine predictors of unsatisfactory resident quality of life during trauma rotations. METHOD: This was a prospective observational study in which we chose orthopedic trauma rotations within 2 training programs at 3 level 1 trauma centres. A sample of 15 orthopedic surgery residents participated in the study. The main outcome measure was the 36-Item Short-Form Health Survey taken at baseline, 2 and 6 months into the rotation. Residents ranked level of stress for 15 work-related and 13 individual problems on 5-point Likert scales. RESULTS: The residents ranged from training years 1 through 5, and their mean age was 31 (standard deviation [SD] 2.8) years. Fear of error decreased at 6 months, compared with baseline (p = 0.007). Lack of time for family decreased as a problem at 2 and 6 months, compared with baseline (p = 0.025). Baseline Physical Component Summary scores were above population norms (p = 0.007). At 2 months, scores for the concept role limitations (physical) decreased significantly (p = 0.019), compared with the baseline. Mean Physical Component Summary scores declined from 57.59 (SD 3.51) at baseline to 53.68 (SD 6.50) at 2 months (p = 0.015) and 53.94 (SD 3.52) at 6 months (p = 0.008). At 2 months, mean general health scores significantly decreased, compared with baseline (p = 0.022). Social functioning scores at 6 months were decreased from population norms (p = 0.02). More resident social time was spent with medical people exclusively at 6 months, compared with baseline (p < 0.02). CONCLUSION: Trauma rotations affect residents' emotional well-being. Training programs should equip residents with coping strategies to improve quality of life during trauma rotations.
