Surgical teaching: how should neurosurgeons handle the conflict of duty to today's patients with the duty to tomorrow's?

Caregiver knowledge, opinion, and willingness to consent to trainee involvement in pediatric surgical care

PURPOSE

Surgical training is shifting toward competency-based models that promote earlier supervised autonomy. We assessed caregiver knowledge, willingness to consent, and opinions regarding trainee autonomy in their child's operation.

METHODS

At two academic children's hospitals, 100 caregivers of children aged 0-17 years completed an electronic survey in the pediatric surgery clinic (1/2018-4/2018). Knowledge, willingness to consent, and opinions of trainee involvement in their child's operation in standard and competency-based training models were assessed. McNemar's test compared willingness to consent with standard and competency-based training (p < 0.05).

RESULTS

Caregivers were 75% female, 41% age 30-39 years old, and 78% white. All provider roles were correctly identified by 14% of caregivers. For routine procedures, caregivers would consent to a fellow assisting (95%) or independently operating with the attending present (78%). They would less likely consent if the attending was not in the operating room (39%) or the hospital (25%). Competency-based training improved willingness to consent, but was significant only for independence with the attending present. Most caregivers wanted to know about (81%) and be asked permission for (82%) trainee involvement in their child's operation.

CONCLUSIONS

This study suggests that surgeons in academic settings must balance transparency with trainee autonomy when obtaining caregiver consent.

Association of Preoperative Disclosure of Resident Roles With Informed Consent for Cataract Surgery in a Teaching Program

IMPORTANCE

Cataract surgery is the most commonly performed intraocular surgery. Academic centers have mandates to train the next surgeon generation, but resident roles are often hidden in the consent process.

OBJECTIVE

To investigate associations of full preoperative disclosure of the resident role with patient consent rates and subjective experience of the consent process.

DESIGN, SETTING, AND PARTICIPANTS

Full scripted disclosure of residents' roles in cataract surgery was delivered by the attending surgeon. Qualitative analysis was conducted from recorded interviews of patients postoperatively regarding consent process experience and choice of whether to allow resident participation. Associations were sought regarding demographic characteristics and consent rates. Patients were recruited though a private community office. Surgery was performed at a single hospital where resident training was routinely conducted. The study included systemically well patients older than 18 years with surgical cataract. They had no previous eye surgery, English fluency, and ability to engage in informed consent decision-making and postsurgery interview. Patients were ineligible if they had monocular cataracts, required additional simultaneous procedures, had history of ocular trauma, or had cataracts that were surgically technically challenging beyond the usual resident skill level.

INTERVENTIONS

Eligible patients received an informed consent conversation by the attending physician in accordance with a script describing projected resident involvement in their cataract surgery. Postoperatively, patients were interviewed and responses were analyzed with a quantitative and thematic qualitative approach.

MAIN OUTCOMES AND MEASURES

Consent rates to resident participation and qualitative experience of full disclosure process.

RESULTS

Ninety-six patients participated. Participants were between ages 50 and 88 years, 53 were men (55.2%), and 75 were white (85.2%). A total of 54 of 96 participants (56.3%; 95% CI, 45.7%-66.4%) agreed to resident involvement. There were no associations between baseline characteristics and consent to resident involvement identified with any confidence, including race/ethnicity (60% [45 of 75] in white patients vs 30.8% [4 of 13] in nonwhite patients; difference, 29.2%; 95% CI, -0.7% to 57.3%; Fisher exact P = .07). Thematically, those who agreed to resident involvement listed trust in the attending surgeon, contributing to education, and supervision as contributing factors. Patients who declined stated fear and perceived risk as reasons.

CONCLUSIONS AND RELEVANCE

Our results suggest 45.7% to 66.4% of community private practice patients would consent to resident surgery. Consent rates were not associated with demographic factors. Because residents are less often offered the opportunity to do surgery on private practice patients vs academic center patients, this may represent a resource for resident education.

Wrong site surgery! How can we stop it?

Introduction:

“Primum non nocere” (first do no harm): Hippocrates (c. 460 BC-377 BC). Wrong site surgery is the fourth commonest sentinel event after patient suicide, operative and post-operative complications, and medication errors. Misinterpretation of the clinic letters or radiology reports is the commonest reason for the wrong site being marked before surgery.

Materials and Methods:

We analyzed 50 cases each of operations carried out on the kidney, ureter, and the testis. The side mentioned on clinic letters, the consent form, and radiology reports lists were also studied. The results were analyzed in detail to determine where the potential pitfalls were likely to arise.

Results:

A total of 803 clinic letters from 150 cases were reviewed. The side of disease was not documented in 8.71% and five patients had the wrong side mentioned in one of their clinic letters. In the radiology reports, the side was not mentioned in three cases and it was reported wrongly in two patients. No wrong side was ever consented for and no wrong side surgery was performed.

Conclusion:

The side of surgery was not always indicated in clinic letter, theatre list, or the consent form despite the procedure being carried on a bilateral organ. As misinterpretation is a major cause of wrong side surgery, it is prudent that the side is mentioned every time in every clinic letter, consent form, and on the theatre list. The WHO surgical safety checklist has already been very effective in minimizing the wrong site surgery in the National Health Service.

Conflicts of interest in medical practice

It has become more and more apparent that some aspects of current medical practice can no longer be kept solely within the private preserve of the profession. Medical error is now treated in an open fashion because it is clear that frank debate over its incidence, causes and mechanisms are crucial to effective prevention. This has always been one of our worst kept secrets. Equally conflicts of interest [1] assume particular relevance in an occupation whose foundation values demand a robust ethical identity. This is the topic of this essay.

How does the participation of a resident surgeon in procedures for small intracranial aneurysms impact patient outcome?

Object

In this paper the authors' goal was to evaluate whether resident neurosurgeons participating in entry-level aneurysm surgery have a negative impact on patient outcomes.

Methods

The authors searched the database for entry-level aneurysm surgeries (that is, those ≤ 10 mm and located in the internal carotid artery [beyond the paraclinoid segment] and middle cerebral artery) performed in 1991 through 2005. The presence or absence of an advanced resident (in his/her last 3 years of residency) was noted. The analysis was examined in 3-year quintiles.

A total of 355 cases (196 with resident participation and 159 without) were evaluated. Permanent adverse outcomes were seen in 11 patients (3.1% of the total study population), all due to branch artery occlusion. The incidence of permanent adverse outcomes in the first 3 years was 10.7% and 2.4% thereafter. This difference was statistically significant (p = 0.015). There was no difference in the incidence of adverse outcomes when comparing surgery performed with and without participation of an advanced resident.

Conclusions

In this study the authors have demonstrated a learning curve in this series of patients. This study also suggests that involving residents in the repair of small unruptured aneurysms will not compromise patient care. In addition, patients can be informed that the team approach to their surgery is at least as good as having the experienced surgeon performing all aspects of the surgery.

Objective surgical skill assessment: the diagonal operating matrix☆

There is an urgent need for structured surgical training and assessment due to the reduction in the training duration with the European Working Time Directive (EWTD). We propose a model for objective skill assessment, the PAR-Diagonal Operating Matrix (PAR-DOM) which breaks down the task of vascular anastomosis into clearly defined skills. The PAR-DOM is made up of a 3x5 table and progress is made along vectors defined on the x-axis as PAR and on the y-axis as four levels. PAR defines three skills at each level. Each skill is graded from 1-3 (this may be taken as below average, average, above average). The skills at various levels are: Level 0 - Posture, Address, Relaxation; Level 1 - Pick-up, Airtime, Rotation; Level 2 - Placing, Angles, Rhythm; Level 3 - Precision, Adaptability, Reproducibility; Level 4 - Pace, Awareness, Relations. The PAR-DOM matrix provides a graphic representation of the progress of trainees over their training period assigned for them to stay with the trainer and also help identify individual strengths and weaknesses.

Is there a "July phenomenon" in pediatric neurosurgery at teaching hospitals?

OBJECT

Concern for patient safety, among other reasons, recently prompted sweeping changes in resident work policies in the US. Some have speculated that the arrival of new interns and residents at teaching hospitals each July might cause an annual transient increase in poor patient outcomes and inefficient care.

METHODS

Data were analyzed for 4323 craniotomies for tumor resection and 22,072 shunt operations performed in pediatric patients between 1988 and 2000 in US nonfederal hospitals (Nationwide Inpatient Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, Rockville, MD). In-hospital mortality rates, discharge outcome, complications, and efficiency measures (length of stay [LOS] and hospital charges) for patients treated in July and August were compared with similar data for patients in other months. There were no significant increases in any adverse end point for either tumor or shunt operations in July and August. Odds ratios (95% confidence interval [CI]) for outcome of tumor craniotomies performed in July and August compared with outcome for tumor craniotomies performed in other months were as follows: for mortality rate, 0.43 (0.14-1.32); for adverse discharge disposition, 1.03 (0.71-1.51); for neurological complications, 1.00 (0.63-1.59); for transfusion, 0.70 (0.41-1.19). Hospital charges were 0.5% lower (range -6 to 5%) in July and August, and LOS was 3% shorter (range -8 to 3%). Odds ratios (95% CI) for July or August shunt surgery compared with shunt surgery performed in other months were as follows: for mortality rate, 0.96 (0.58-1.60); for adverse discharge disposition, 0.85 (0.66-1.11); for neurological complications, 1.27 (0.75-2.16); for transfusion, 0.81 (0.48-1.37). Hospital charges were 0.2% higher in July and August (range -3 to 3%), and LOS was 3% shorter (range -5 to 0.5%).

CONCLUSIONS

Although moderate increases in some adverse end points could not be excluded, there was no evidence that brain tumor or shunt surgery performed in pediatric patients at US teaching hospitals during July and August is associated with more frequent adverse patient outcome or inefficient care than similar surgery performed during other months.

Surgery for primary brain tumors at United States academic training centers: results from the Residency Review Committee for neurological surgery

OBJECT

Surgery for primary brain tumors has been an important index of the quality of neurosurgical training programs in the US. The scope of such cases and the proportion of surgeries performed transsphenoidally are an interesting means of tracking the effectiveness of residency education.

METHODS

Program Information Forms from the 94 American Council for Graduate Medical Education-approved US neurosurgical residency programs were reviewed for the period between 2000 and 2003. Particular attention was focused on an analysis of the cases requiring craniotomy for primary brain tumor and transsphenoidal surgery. The mean annual number of primary brain tumor cases per program was 195, with a range from 36 to 724 cases. The proportion of primary brain tumors accessed transsphenoidally was 20%. The mean annual number of transsphenoidal operations performed at academic training centers was 39. A wide range in the frequency of transsphenoidal cases from one program to another was also noted. Almost one third of training centers performed fewer than 20 transsphenoidal operations annually and 80% performed fewer than 50.

CONCLUSIONS

Most neurosurgical training programs provide residents with excellent experience in craniotomy for primary brain tumors. Practice with transsphenoidal surgery, however, is less well represented and tends to be clustered at several active centers. The implications for neurosurgical education are significant.

Safety of intracranial aneurysm surgery performed in a postgraduate training program: implications for training

OBJECT

Patient care and educational experience have long formed a dichotomy in modem surgical training. In neurosurgery, achieving a delicate balance between these two factors has been challenged by recent trends in the field including increased subspecialization, emerging technologies, and decreased resident work hours. In this study the authors evaluated the experience profiles of neurosurgical trainees at a large Canadian academic center and the safety of their practice on patient care.

METHODS

Two hundred ninety-three patients who underwent surgery for intracranial aneurysm clipping between 1993 and 1996 were selected. Prospective data were available in 167 cases, allowing the operating surgeon to be identified. Postoperative data and follow-up data were gathered retrospectively to measure patient outcomes. In 167 cases, a total of 183 aneurysms were clipped, the majority (91%) by neurosurgical trainees. Trainees performed dissections on aneurysms that were predominantly small (< 1.5 cm in diameter; 77% of patients) and ruptured (64% of patients). Overall mortality rates for the patients treated by the trainee group were 4% (two of 52 patients) and 9% (nine of 100 patients) for unruptured and ruptured aneurysm cases, respectively. Patient outcomes were comparable to those reported in historical data. Staff members appeared to be primary surgeons in a select subset of cases.

CONCLUSIONS

Neurosurgical trainees at this institution are exposed to a broad spectrum of intracranial aneurysms, although some case selection does occur. With careful supervision, intracranial aneurysm surgery can be safely delegated to trainees without compromising patient outcomes. Current trends in practice patterns in neurosurgery mandate ongoing monitoring of residents' operative experience while ensuring continued excellence in patient care.
