Surgeon Ratings of the Severity of Idiopathic Median Neuropathy at the Carpal Tunnel Are Not Influenced by Magnitude of Incapability

Surgeon Prioritization of Mental, Social, and Pathophysiological Aspects of Health Among People With Traumatic and Nontraumatic Musculoskeletal Conditions

BACKGROUND

There is mounting evidence that, among musculoskeletal patients, variation in capability has more notable associations with variations in mental and social health factors than with variation in pathophysiology severity. This study sought factors that could limit the integration of this evidence into more comprehensive care models.

METHODS

In two scenario-based experiments, surgeon participants in an international collaborative, the Science of Variation Group, reviewed scenarios of (a) nontraumatic (83 participants) and (b) trauma-related (130 participants) pathophysiologies for which tests and treatments were discretionary. The following demographic, mental, and social health elements were varied randomly: sex, age, race/ethnicity, mindsets, social health aspects, and specific pathophysiologies. For each scenario, participants rated their likelihood to offer surgery (continuous) and their sense of presence of an opportunity to address better mental or social health in treatment (yes or no). Factors associated with each rating were sought in multivariable analysis.

RESULTS

Greater likelihood to offer discretionary surgery for nontraumatic pathophysiologies was associated with greater pathophysiology severity, trapeziometacarpal arthritis, and greater distress and unhelpful thoughts regarding symptoms. Lateral elbow enthesopathy was associated with a lower likelihood. For trauma-related pathophysiologies, an ankle fracture with slight articular subluxation was associated with greater likelihood to offer surgery, and several other trauma-related pathophysiologies were associated with a lower likelihood. For both nontraumatic and trauma-related pathophysiologies, surgeons noticed unhelpful thinking, distress, and social issues as reasons to consider addressing mental and social health in treatment, relatively independent of pathophysiology.

CONCLUSION

Surgeons seem to recognize opportunities to address mental and social needs but ultimately base their decision to offer discretionary surgery on pathophysiological factors.

CLINICAL RELEVANCE

Comprehensive, whole-person care for musculoskeletal illness might be supported by strategies for ensuring that aspects of stress and distress that contribute to greater symptom intensity are not misinterpreted as a reflection of greater pathophysiology severity.

Variation in Interpretation of Provocative Tests for Carpal Tunnel Syndrome

PURPOSE

We studied variation in interpretation of specific symptoms during clinical tests for carpal tunnel syndrome to estimate the degree to which surgeons consider pain without paresthesia characteristic of median neuropathy.

METHODS

We invited all upper-extremity surgeon members of the Science of Variation Group to complete a scenario-based experiment. Surgeons read 5-10 clinical vignettes of patients with variation in patient demographics and random variation in symptoms and signs as follows: primary symptoms (nighttime numbness and tingling, constant numbness and loss of sensibility, pain with activity), symptoms elicited by a provocative test (Phalen, Durkan, or Tinel) (tingling, pain), and location of symptoms elicited by the provocative test (index and middle fingers, thumb and index fingers, little and ring fingers, entire hand).

RESULTS

Patient factors associated with surgeon interpretation of provocative tests as negative included pain rather than paresthesia during the Phalen, Durkan, or Tinel test and location of symptoms in the entire hand rather than the median nerve distribution.

CONCLUSIONS

Specialists do not consider pain without paresthesia or a noncharacteristic symptom distribution as characteristic of carpal tunnel syndrome.

CLINICAL RELEVANCE

Awareness that elicitation of pain with Phalen, Durkan, and Tinel tests is regarded by specialists as relatively uncharacteristic of median neuropathy can help limit the potential for both overdiagnosis and overtreatment of median neuropathy as well as underdiagnosis and undertreatment of mental and social health contributions to illness (notable correlates of the intensity and distribution of pain).

Surgeon Implicit Association of Women With Supportive Roles in Medicine

BACKGROUND

In a previous study, we documented patient implicit bias that surgeons are men. As a next step, we tested the implicit bias of surgeons that women in medicine have leading (chair, surgeon) or supporting roles (medical assistant, physician assistant).

QUESTIONS/PURPOSE

(1) What is the relationship between the implicit associations and expressed beliefs of surgeons regarding women as leaders in medicine? (2) Are there factors associated with surgeon implicit association and explicit preference regarding the roles of women in medicine?

METHODS

A total of 102 musculoskeletal surgeon members of the Science of Variation Group (88 men and 12 women) completed an implicit association test (IAT) of implicit bias regarding sex and lead/support roles in medicine and a questionnaire that addressed respondent demographics and explicit preference regarding women's roles. The IAT consisted of seven rounds with five rounds used for teaching and two rounds for evaluation.

RESULTS

On average, there was an implicit association of women with supportive roles (D-score: -48; SD 4.7; P < 0.001). The mean explicit preference was for women in leadership roles (median: 73; interquartile ranges: 23 to 128; P < 0.001). There was a correlation between greater explicit preference for women in a leading role and greater implicit bias toward women in a supporting role (ρ = 0.40; P < 0.001). Women surgeons and shoulder and elbow specialists had less implicit bias that women have supporting roles.

CONCLUSION

The observation that musculoskeletal surgeons have an explicit preference for women in leading roles in medicine but an implicit bias that they have supporting roles-more so among men surgeons-documents the gap between expressed opinions and ingrained mental processing that is the legacy of the traditional "roles" of women in medicine and surgery. To resolve this gap, we will need to be intentional about promotion of and emersion in experiences where the leader is a woman.

Diagnosis of Mild-to-moderate Idiopathic Median Neuropathy at the Carpal Tunnel Based on Signs and Symptoms is Discordant From Diagnosis Based on Electrodiagnostic Studies and Ultrasound

BACKGROUND

Although idiopathic median neuropathy at the carpal tunnel (IMNCT) is objective and verifiable, distinction of normal and abnormal nerves is imprecise and probabilistic. The associated symptoms and signs (carpal tunnel syndrome [CTS]) vary, particularly for nonsevere (mild and moderate) median neuropathy. Discordance between diagnosis of mild or moderate median neuropathy at the carpal tunnel using symptoms and signs and diagnosis based on objective tests is a measure of the potential for overdiagnosis and overtreatment.

QUESTION/PURPOSE

What is the difference in the estimated prevalence of mild-to-moderate IMNCT using nonsevere signs and symptoms compared with the estimated prevalence using electrodiagnostic studies (EDS) and ultrasound (US)?

METHODS

We used data from an existing cross-sectional data registry. To create this registry, between January 2014 and January 2019, we considered all new adult English-speaking people who had an EDS that included the median nerve or people with a diagnosis of CTS who did not have surgery yet. A small and unrecorded number of people declined participation. The cross-sectional area of the median nerve at the distal wrist crease using US in people who already had EDS was measured. People with a diagnosis of CTS underwent both EDS and US. The six signs and symptoms of Carpal Tunnel Syndrome 6 (CTS-6, a validated tool to estimate the probability of IMNCT using ratings of symptoms and signs of CTS) were recorded. This resulted in a registry of 185 participants; we excluded 75 people for obvious, severe IMNCT (defined as nonrecordable nerve conduction velocity, thenar atrophy, or greater than 5 mm 2-point discrimination). Three of the 110 qualifying patients had missing information on ethnicity or race, but we accounted for this in our final analysis. Without a reference standard, as is the case with IMNCT, latent class analysis (LCA) can be used to establish the probability that an individual has specific pathophysiologic findings. LCA is a statistical method that identifies sets of characteristics that tend to group together. This technique has been used, for example, in diagnosing true scaphoid fractures among suspected fractures based on a combination of demographic, injury, examination, and radiologic variables. The prevalence of mild-to-moderate IMNCT was estimated in two LCAs using four signs and symptoms characteristic of mild-to-moderate IMNCT, as well as EDS and US measures of median neuropathy.

RESULTS

The estimated prevalence of mild-to-moderate IMNCT based on signs and symptoms was 73% (95% CI 62% to 81%), while the estimated prevalence using EDS and US measurements was 51% (95% CI 37% to 65%).

CONCLUSION

The notable discordance of 22% between the estimated prevalence of mild-to-moderate IMNCT using signs and symptoms and prevalence based on EDS and US criteria, and the overlapping CIs of the probability estimations, indicate considerable uncertainty and a corresponding notable potential for underdiagnosis or overdiagnosis. When signs and symptoms suggest mild-to-moderate median neuropathy and surgery is being considered, patients and clinicians might consider additional testing, such as EDS or US, to increase the probability of actual median neuropathy that can benefit from surgery. We might benefit from a more accurate and reliable diagnostic strategy or tool for mild-to-moderate IMNCT; this might be the focus of a future study.

Factors Associated With Comfort Using Telemedicine for Upper Limb Specialty Care

PURPOSE

There is a growing interest in diagnosis and treatment through telemedicine because of its convenience, accessibility, and lower costs. There are clinician and patient barriers to wider adoption of telemedicine. To support the effective and equitable use of telemedicine, we investigated the patient, illness, and surgeon factors associated with the specialist level of comfort in providing upper limb care via telemedicine.

METHODS

Seventy-five upper-extremity musculoskeletal specialists completed an online survey-based experiment in which they viewed 12 patient scenarios with randomized patient age, gender, diagnosis, pain intensity, and patient preference for surgical treatment (yes or no) and rated their comfort with telemedicine from 0, no comfort, to 10, complete comfort. The participants were able to provide a rationale for their stance in open text boxes. We recorded the following specialist factors: gender, location of practice, years in practice, subspecialty, the supervision of trainees, and surgeon-rated importance of a physical examination.

RESULTS

In a multivariable analysis, greater surgeon comfort using telemedicine was associated with nontrauma conditions, four specific diagnoses, and patients who did not have severe pain. Lower surgeon comfort with telemedicine was associated with the higher clinician-rated importance of a hands-on physical examination and supervising trainees. Text-based reasons provided for relative comfort with telemedicine included nonsurgical treatment and facility of diagnosis based on interviews alone. Text-based reasons for relative discomfort with telemedicine included a perceived need for a hands-on physical examination and a preference for an in-person conversation for specific discussions, including scheduling surgery.

CONCLUSIONS

Greater specialist enthusiasm for telemedicine is associated with personal preferences regarding the upper-extremity condition, patients with less severe pain, and a willingness to forego a hands-on examination.

CLINICAL RELEVANCE

Utilization of telemedicine for upper-extremity specialty care may be facilitated by diagnosis-specific care strategies and strategies for video examination, with a focus on tactics that are effective for people with more intense symptoms.

Factors associated with surgeon recognition of mental health care opportunities and inclination to attend to mental health

PURPOSE

A notable percentage of people that die by suicide have had a medical visit within a few months of their death. In a survey-based experiment, we evaluated: 1) whether there are any surgeon, setting, or patient factors associated with surgeon rating of mental health care opportunities, and 2) if there are any surgeon, setting, or patient factors associated with likelihood of mental health referrals.

METHODS

One hundred and twenty-four upper extremity surgeons of the Science of Variation Group viewed five scenarios of a person with one orthopedic condition. The following aspects of the scenarios were independently randomized: Social worker or psychologist available, office workload, socioeconomic status, gender, age, mental health factors, mental health clues, and diagnosis.

RESULTS

Accounting for potential confounders, surgeon likelihood of discussing mental health was associated with cancer, disadvantaged socioeconomic status, mental health factors other than being shy, prior suicide attempt, history of physical or emotional abuse, isolation, and when the office is not busy. Factors independently associated with higher likelihood of referring a patient for mental health care included cancer, disadvantaged socioeconomic status, mental health cues, mental health risk factors, and a social worker or psychologist available in the office.

CONCLUSION

Using random elements in fictitious scenarios we documented that specialist surgeons are aware of and attuned to mental health care opportunities, are motivated to discuss notable cues, and will make mental health referrals, in part influenced by convenience.
