Postgame analysis: Using video-based coaching for continuous professional development

BACKGROUND The surgical learning curve persists for years after training, yet existing continuing medical education activities targeting this are limited. We describe a pilot study of a scalable video-based intervention, providing individualized feedback on intraoperative performance. STUDY DESIGN Four complex operations performed by surgeons of varying experience--a chief resident accompanied by the operating senior surgeon, a surgeon with less than 10 years in practice, another with 20 to 30 years in practice, and a surgeon with more than 30 years of experience--were video recorded. Video playback formed the basis of 1-hour coaching sessions with a peer-judged surgical expert. These sessions were audio recorded, transcribed, and thematically coded. RESULTS The sessions focused on operative technique--both technical aspects and decision-making. With increasing seniority, more discussion was devoted to the optimization of teaching and facilitation of the residents technical performance. Coaching sessions with senior surgeons were peer-to-peer interactions, with each discussing his preferred approach. The coach alternated between directing the session (asking probing questions) and responding to specific questions brought by the surgeons, depending on learning style. At all experience levels, video review proved valuable in identifying episodes of failure to progress and troubleshooting alternative approaches. All agreed this tool is a powerful one. Inclusion of trainees seems most appropriate when coaching senior surgeons; it may restrict the dialogue of more junior attendings. CONCLUSIONS Video-based coaching is an educational modality that targets intraoperative judgment, technique, and teaching. Surgeons of all levels found it highly instructive. This may provide a practical, much needed approach for continuous professional development.

Physicians' Needs in Coping With Emotional Stressors: The Case for Peer Support

OBJECTIVE To design an evidence-based intervention to address physician distress, based on the attitudes toward support among physicians at our hospital. DESIGN, SETTING, AND PARTICIPANTS A 56-item survey was administered to a convenience sample (n = 108) of resident and attending physicians at surgery, emergency medicine, and anesthesiology departmental conferences at a large tertiary care academic hospital. MAIN OUTCOME MEASURES Likelihood of seeking support, perceived barriers, awareness of available services, sources of support, and experience with stress. RESULTS Among the resident and attending physicians, 79% experienced either a serious adverse patient event and/or a traumatic personal event within the preceding year. Willingness to seek support was reported for legal situations (72%), involvement in medical errors (67%), adverse patient events (63%), substance abuse (67%), physical illness (62%), mental illness (50%), and interpersonal conflict at work (50%). Barriers included lack of time (89%), uncertainty or difficulty with access (69%), concerns about lack of confidentiality (68%), negative impact on career (68%), and stigma (62%). Physician colleagues were the most popular potential sources of support (88%), outnumbering traditional mechanisms such as the employee assistance program (29%) and mental health professionals (48%). Based on these results, a one-on-one peer physician support program was incorporated into support services at our hospital. CONCLUSIONS Despite the prevalence of stressful experiences and the desire for support among physicians, established services are underused. As colleagues are the most acceptable sources of support, we advocate peer support as the most effective way to address this sensitive but important issue.

Protecting patients from an unsafe system: the etiology and recovery of intraoperative deviations in care.

Objective:To understand the etiology and resolution of unanticipated events in the operating room (OR). Background:The majority of surgical adverse events occur intraoperatively. The OR represents a complex, high-risk system. The influence of different human, team, and organizational/environmental factors on safety and performance is unknown. Methods:We video-recorded and transcribed 10 high-acuity operations, representing 43.7 hours of patient care. Deviations, defined as delays and/or episodes of decreased patient safety, were identified by majority consensus of a multidisciplinary team. Factors that contributed to each event and/or mitigated its impact were determined and attributed to the patient, providers, or environment/organization. Results:Thirty-three deviations (10 delays, 17 safety compromises, 6 both) occurred—with a mean of 1 every 79.4 minutes. These deviations were multifactorial (mean 3.1 factors). Problems with communication and organizational structure appeared repeatedly at the root of both types of deviations. Delays tended to be resolved with vigilance, communication, coordination, and cooperation, while mediation of safety compromises was most frequently accomplished with vigilance, leadership, communication, and/or coordination. The organization/environment was not found to play a direct role in compensation. Conclusions:Unanticipated events are common in the OR. Deviations result from poor organizational/environmental design and suboptimal team dynamics, with caregivers compensating to avoid patient harm. Although recognized in other high-risk domains, such human resilience has not yet been described in surgery and has major implications for the design of safety interventions.

Impact of neoadjuvant chemotherapy on breast reconstruction

With advances in oncologic treatment, cosmesis after mastectomy has assumed a pivotal role in patient and provider decision making. Multiple studies have confirmed the safety of both chemotherapy before breast surgery and immediate reconstruction. Little has been written about the effect of neoadjuvant chemotherapy on decisions about reconstruction.

Deconstructing intraoperative communication failures.

BACKGROUND Communication failure is a common contributor to adverse events. We sought to characterize communication failures during complex operations. METHODS We video recorded and transcribed six complex operations, representing 22 h of patient care. For each communication event, we determined the participants and the content discussed. Failures were classified into four types: audience (key individuals missing), purpose (issue nonresolution), content (insufficient/inaccurate information), and/or occasion (futile timing). We added a systems category to reflect communication occurring at the organizational level. The impact of each identified failure was described. RESULTS We observed communication failures in every case (mean 29, median 28, range 13-48), at a rate of one every 8 min. Cross-disciplinary exchanges resulted in failure nearly twice as often as intradisciplinary ones. Discussions about or mandated by hospital policy (20%), personnel (18%), or other patient care (17%) were most error prone. Audience and purpose each accounted for >40% of failures. A substantial proportion (26%) reflected flawed systems for communication, particularly those for disseminating policy (29% of system failures), coordinating personnel (27%), and conveying the procedure planned (27%) or the equipment needed (24%). In 81% of failures, inefficiency (extraneous discussion and/or work) resulted. Resource waste (19%) and work-arounds (13%) also were frequently seen. CONCLUSIONS During complex operations, communication failures occur frequently and lead to inefficiency. Prevention may be achieved by improving synchronous, cross-disciplinary communication. The rate of failure during discussions about/mandated by policy highlights the need for carefully designed standardized interventions. System-level support for asynchronous perioperative communication may streamline operating room coordination and preparation efforts.

High-Cost Imaging in Elderly Patients with Stage IV Cancer

BACKGROUND Medicare expenditures for high-cost diagnostic imaging have risen faster than those for total cancer care and have been targeted for potential cost reduction. We sought to determine recent and long-term patterns in high-cost diagnostic imaging use among elderly (aged ≥65 years) patients with stage IV cancer. METHODS We identified claims within the Surveillance, Epidemiology, and End Results (SEER)-Medicare database with computed tomography, magnetic resonance imaging, positron emission tomography, and nuclear medicine scans between January 1994 and December 2009 for patients diagnosed with stage IV breast, colorectal, lung, or prostate cancer between January 1995 and December 2006 (N = 100,594 patients). The proportion of these patients imaged and rate of imaging per-patient per-month of survival were calculated for each phase of care in patients diagnosed between January 2002 and December 2006 (N = 55,253 patients). Logistic regression was used to estimate trends in imaging use in stage IV patients diagnosed between January 1995 and December 2006, which were compared with trends in imaging use in early-stage (stages I and II) patients with the same tumor types during the same period (N = 192,429 patients). RESULTS Among the stage IV patients diagnosed between January 2002 and December 2006, 95.9% underwent a high-cost diagnostic imaging procedure, with a mean number of 9.79 (SD = 9.77) scans per patient and 1.38 (SD = 1.24) scans per-patient per-month of survival. After the diagnostic phase, 75.3% were scanned again; 34.3% of patients were scanned in the last month of life. Between January 1995 and December 2006, the proportion of stage IV cancer patients imaged increased (relative increase = 4.6%, 95% confidence interval [CI] = 3.7% to 5.6%), and the proportion of early-stage cancer patients imaged decreased (relative decrease = -2.5%, 95% CI = -3.2% to -1.9%). CONCLUSIONS Diagnostic imaging is used frequently in patients with stage IV disease, and its use increased more rapidly over the decade of study than that in patients with early-stage disease.

Quantifying technical skills during open operations using video-based motion analysis

INTRODUCTION Objective quantification of technical operative skills in surgery remains poorly defined, although the delivery of and training in these skills is essential to the profession of surgery. Attempts to measure hand kinematics to quantify operative performance primarily have relied on electromagnetic sensors attached to the surgeons hand or instrument. We sought to determine whether a similar motion analysis could be performed with a marker-less, video-based review, allowing for a scalable approach to performance evaluation. METHODS We recorded six reduction mammoplasty operations-a plastic surgery procedure in which the attending and resident surgeons operate in parallel. Segments representative of surgical tasks were identified with Multimedia Video Task Analysis software. Video digital processing was used to extract and analyze the spatiotemporal characteristics of hand movement. RESULTS Attending plastic surgeons appear to use their nondominant hand more than residents when cutting with the scalpel, suggesting more use of countertraction. While suturing, attendings were more ambidextrous, with smaller differences in movement between their dominant and nondominant hands than residents. Attendings also seem to have more conservation of movement when performing instrument tying than residents, as demonstrated by less nondominant hand displacement. These observations were consistent within procedures and between the different attending plastic surgeons evaluated in this fashion. CONCLUSION Video motion analysis can be used to provide objective measurement of technical skills without the need for sensors or markers. Such data could be valuable in better understanding the acquisition and degradation of operative skills, providing enhanced feedback to shorten the learning curve.

Development of a List of High-Risk Operations for Patients 65 Years and Older

IMPORTANCE No consensus exists regarding the definition of high-risk surgery in older adults. An inclusive and precise definition of high-risk surgery may be useful for surgeons, patients, researchers, and hospitals. OBJECTIVE To develop a list of high-risk operations. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study and modified Delphi procedure. The setting included all Pennsylvania acute care hospitals (Pennsylvania Health Care Cost Containment Council [PHC4] April 1, 2001, to December 31, 2007) and a nationally representative sample of US acute care hospitals (Nationwide Inpatient Sample [NIS], Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality January 1, 2001, to December 31, 2006). Patients included were those 65 years and older admitted to PHC4 hospitals and those 18 years and older admitted to NIS hospitals. We identified International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedure codes associated with at least 1% inpatient mortality in the PHC4. We used a modified Delphi procedure with 5 board-certified surgeons to further refine this list by excluding nonoperative procedures and operations that were unlikely to be the proximate cause of mortality and were instead a marker of critical illness (eg, tracheostomy). We then cross-validated this list of ICD-9-CM codes in the NIS. MAIN OUTCOMES AND MEASURES Modified Delphi procedure consensus of at least 4 of 5 panelists and proportion agreement in the NIS. RESULTS Among 4,739,522 admissions of patients 65 years and older in the PHC4, a total of 2,569,589 involved a procedure, encompassing 2853 unique procedures. Of 1130 procedures associated with a crude inpatient mortality of at least 1%, 264 achieved consensus as high-risk operations by the modified Delphi procedure. The observed inpatient mortality in the NIS was at least 1% for 227 of 264 procedures (86%) in patients 65 years and older. The pooled inpatient mortality for these identified high-risk procedures performed on patients 65 years and older was double the pooled inpatient mortality for correspondingly identified high-risk operations for patients younger than 65 years (6% vs 3%). CONCLUSIONS AND RELEVANCE We developed a list of procedure codes to identify high-risk surgical procedures in claims data. This list of high-risk operations can be used to standardize the definition of high-risk surgery in quality and outcomes-based studies and to design targeted clinical interventions.

The primary determinants of radiation use during fixation of proximal femur fractures

OBJECTIVES To establish the primary determinants of operative radiation use during fixation of proximal femur fractures. DESIGN Retrospective cohort study. SETTING Level I trauma centre. COHORT 205 patients treated surgically for subtrochanteric and intertrochanteric femoral fractures. MAIN OUTCOME MEASURES Fluoroscopy time, dose-area-product (DAP). RESULTS Longer fluoroscopy time was correlated with higher body mass index (p=0.04), subtrochanteric fracture (p<0.001), attending surgeon (p=0.001), and implant type (p<0.001). Increased DAP was associated with higher body mass index (p<0.001), subtrochanteric fracture (p=0.002), attending surgeon (p=0.003), lateral body position (p<0.001), and implant type (p=0.05). CONCLUSION The strongest determinants of radiation use during surgical fixation of intertrochanteric and subtrochanteric femur fractures were location of fracture, patient body position, patient body mass index, and the use of cephalomedullary devices. Surgeon style, presumably as it relates to teaching efforts, seems to strongly influence radiation use.

Complementing Operating Room Teaching With Video-Based Coaching

Importance Surgical expertise demands technical and nontechnical skills. Traditionally, surgical trainees acquired these skills in the operating room; however, operative time for residents has decreased with duty hour restrictions. As in other professions, video analysis may help maximize the learning experience. Objective To develop and evaluate a postoperative video-based coaching intervention for residents. Design, Setting, and Participants In this mixed methods analysis, 10 senior (postgraduate year 4 and 5) residents were videorecorded operating with an attending surgeon at an academic tertiary care hospital. Each video formed the basis of a 1-hour one-on-one coaching session conducted by the operative attending; although a coaching framework was provided, participants determined the specific content collaboratively. Teaching points were identified in the operating room and the video-based coaching sessions; iterative inductive coding, followed by thematic analysis, was performed. Main Outcomes and Measures Teaching points made in the operating room were compared with those in the video-based coaching sessions with respect to initiator, content, and teaching technique, adjusting for time. Results Among 10 cases, surgeons made more teaching points per unit time (63.0 vs 102.7 per hour) while coaching. Teaching in the video-based coaching sessions was more resident centered; attendings were more inquisitive about residents’ learning needs (3.30 vs 0.28, P = .04), and residents took more initiative to direct their education (27% [198 of 729 teaching points] vs 17% [331 of 1977 teaching points], P < .001). Surgeons also more frequently validated residents’ experiences (8.40 vs 1.81, P < .01), and they tended to ask more questions to promote critical thinking (9.30 vs 3.32, P = .07) and set more learning goals (2.90 vs 0.28, P = .11). More complex topics, including intraoperative decision making (mean, 9.70 vs 2.77 instances per hour, P = .03) and failure to progress (mean, 1.20 vs 0.13 instances per hour, P = .04) were addressed, and they were more thoroughly developed and explored. Excerpts of dialogue are presented to illustrate these findings. Conclusions and Relevance Video-based coaching is a novel and feasible modality for supplementing intraoperative learning. Objective evaluation demonstrates that video-based coaching may be particularly useful for teaching higher-level concepts, such as decision making, and for individualizing instruction and feedback to each resident.
