Surgeon symptoms, strain, and selections: Systematic review and meta-analysis of surgical ergonomics

Background

Many surgeons experience work-related pain and musculoskeletal symptoms; however, comprehensive reporting of surgeon ailments is lacking in the literature. We sought to evaluate surgeons' work-related symptoms, possible causes of these symptoms, and to report outcomes associated with those symptoms.

Materials and methods

Five major medical indices were queried for articles published between 1980 and 2014. Included articles evaluated musculoskeletal symptoms and ergonomic outcomes in surgeons. A meta-analysis using a fixed-effect model was used to report pooled results.

Results

Forty articles with 5152 surveyed surgeons were included. Sixty-eight percent of surgeons surveyed reported generalized pain. Site-specific pain included pain in the back (50%), neck (48%), and arm or shoulder (43%). Fatigue was reported by 71% of surgeons, numbness by 37%, and stiffness by 45%. Compared with surgeons performing open surgery, surgeons performing minimally invasive surgery (MIS) were significantly more likely to experience pain in the neck (OR 2.77 [95% CI 1.30–5.93]), arm or shoulder (OR 4.59 [2.19–9.61]), hands (OR 2.99 [1.33–6.71], and legs (OR 12.34 [5.43–28.06]) and experience higher odds of fatigue (8.09 [5.60–11.70]) and numbness (6.82 [1.75–26.65]). Operating exacerbated pain in 61% of surgeons, but only 29% sought treatment for their symptoms. We found no direct association between muscles strained and symptoms.

Conclusions

Most surgeons report work-related symptoms but are unlikely to seek medical attention. MIS surgeons are significantly more likely to experience musculoskeletal symptoms than surgeons performing open surgery. Symptoms experienced do not necessarily correlate with strain.

•

68% of surveyed surgeons reported experiencing generalized pain from operating.

•

Minimally-invasive surgeons were more likely to report pain, fatigue, and numbness.

•

Only 29% of surgeons reported seeking treatment for symptoms.

•

No association between objective strain on muscles and reported symptoms was found.

Improving outcomes in patients with melanoma: strategies to ensure an early diagnosis

Patients with thin, low-risk melanomas have an excellent long-term prognosis and higher quality of life than those who are diagnosed at later stages. From an economic standpoint, treatment of early stage melanoma consumes a fraction of the health care resources needed to treat advanced disease. Consequently, early diagnosis of melanoma is in the best interest of patients, payers, and health care systems. This review describes strategies to ensure that patients receive an early diagnosis through interventions ranging from better utilization of primary care clinics, to in vivo diagnostic technologies, to new "apps" available in the market. Strategies for screening those at high risk due to age, male sex, skin type, nevi, genetic mutations, or family history are discussed. Despite progress in identifying those at high risk for melanoma, there remains a lack of general consensus worldwide for best screening practices. Strategies to ensure early diagnosis of recurrent disease in those with a prior melanoma diagnosis are also reviewed. Variations in recurrence surveillance practices by type of provider and country are featured, with evidence demonstrating that various imaging studies, including ultrasound, computed tomography, positron emission tomography, and magnetic resonance imaging, provide only minimal gains in life expectancy, even for those with more advanced (stage III) disease. Because the majority of melanomas are attributable to ultraviolet radiation in the form of sunlight, primary prevention strategies, including sunscreen use and behavioral interventions, are reviewed. Recent international government regulation of tanning beds is described, as well as issues surrounding the continued use artificial ultraviolet sources among youth. Health care stakeholder strategies to minimize UV exposure are summarized. The recommendations encompass both specific behaviors and broad intervention targets (eg, individuals, social spheres, organizations, celebrities, governments).

The long-term risk of upper-extremity lymphedema is two-fold higher in breast cancer patients than in melanoma patients

BACKGROUND AND OBJECTIVES

We assessed the cumulative incidence, symptoms, and risk factors for upper-extremity lymphedema in breast cancer and melanoma patients undergoing sentinel lymph node biopsy or axillary lymph node dissection.

METHODS

Patients were recruited preoperatively (time 0) and assessed at 6, 12, and 18 months postoperatively. Limb volume change (LVC) was measured by perometry. Lymphedema was categorized as none, mild (LVC 5-9.9%), or moderate/severe (LVC≥10%). Symptoms were assessed with a validated lymphedema instrument. Longitudinal logistic regression analyses were conducted to identify risk factors associated with moderate/severe lymphedema.

RESULTS

Among 205 breast cancer and 144 melanoma patients, the cumulative incidence of moderate/severe lymphedema at 18 months was 36.5% and 35.0%, respectively. However, in adjusted analyses, factors associated with moderate/severe lymphedema were breast cancer (OR 2.0, P = 0.03), body mass index ≥ 30 kg/m(2) (OR 1.6, P = 0.04), greater number of lymph nodes removed (OR 1.05, P < 0.01), and longer interval since surgery (OR 2.33 at 18 months, P < 0.01).

CONCLUSIONS

Lymphedema incidence increased over time in both cohorts. However, the adjusted risk of moderate/severe lymphedema was two-fold higher in breast cancer patients. These results may be attributed to surgical treatment of the primary tumor in the breast and more frequent use of radiation.

Is surviving enough? Coping and impact on activities of daily living among melanoma patients with lymphoedema

We assessed the impact of lymphoedema (defined as ≥ 10% limb volume change) on quality of life (QOL), ability to perform activities of daily living (ADLs) and coping in 277 melanoma patients. Limb volume was measured prospectively, pre-operatively and every 3-6 months for 18 months post-operatively using a perometer. Three questionnaires were administered to measure QOL, coping and impact on ADLs. Statistical analyses were conducted using longitudinal logistic regression models. At 18 months, the cumulative incidence of lymphoedema was 31% in patients with upper extremity nodal basin treatment and 40% in lower extremity nodal basin treatment patients. Patients with lower extremity lymphoedema reported lower QOL scores than those with upper extremity lymphoedema. Over 18 months, both groups with mild and moderate lymphoedema showed improvement in coping [odds ratio (OR): 6.67, 95% confidence interval (CI): 3.30-13.47] and performance of ADLs (OR: 7.46, CI: 3.38-16.47). Over the course of 18 months, men were found to have poorer coping scores than women (OR: 2.91, CI: 1.35-6.27). Lymphoedema was associated with improvement in coping over time (P = 0.08) and a higher reported interference with ADLs (OR: 2.53, CI: 1.29-4.97). Patient education about lymphoedema at the time of surgical consent may improve self-efficacy and coping ability. Effective management of lymphoedema may improve patient QOL and reduce interference with ADLs.

Long-term follow-up for melanoma patients: is there any evidence of a benefit?

As the incidence of melanoma and the number of melanoma survivors continues to rise, optimal surveillance strategies are needed that balance the risks and benefits of screening in the context of contemporary resource use. Detection of recurrences has important implications for clinical management. Most current surveillance recommendations for melanoma survivors are based on low-level evidence with wide variations in practice patterns and an unknown clinical impact for the melanoma survivor.

Recent progress in the treatment and prevention of cancer-related lymphedema

This article provides an overview of the recent developments in the diagnosis, treatment, and prevention of cancer-related lymphedema. Lymphedema incidence by tumor site is evaluated. Measurement techniques and trends in patient education and treatment are also summarized to include current trends in therapeutic and surgical treatment options as well as longer-term management. Finally, an overview of the policies related to insurance coverage and reimbursement will give the clinician an overview of important trends in the diagnosis, treatment, and management of cancer-related lymphedema.

Is surveillance imaging effective for detecting surgically treatable recurrences in patients with melanoma? A comparative analysis of stage-specific surveillance strategies

OBJECTIVE

To guide resource utilization, we aimed to determine the impact of routine surveillance imaging for the detection of melanoma recurrences amenable to surgical resection with curative intent.

BACKGROUND

The National Comprehensive Cancer Network guidelines for melanoma surveillance are largely consensus based.

METHODS

Using single-institution, patient-level data (n = 1600), transition probabilities were calculated for a Markov model simulating the natural history of patients with stage I-III melanoma. As a base estimate, imaging was assumed to detect regional and distant recurrences of which 80% and 20% could be surgically treated with curative intent, respectively. Sensitivity analyses were conducted for all point estimates. For each disease stage, we calculated the number of surgically treatable regional or distant recurrence detected during 5 years per 10,000 patients undergoing computed tomography (CT) or positron emission tomography (PET)/CT scans at 6- or 12-month intervals. The associated positive and negative predictive values and life expectancy were also calculated and compared with clinical examination alone.

RESULTS

At 5-year follow-up, CT or PET/CT at 6-month intervals detected surgically treatable regional or distant recurrence in 6.4% of patients with stage I, 18.5% of stage II, and 33.1% of stage III disease; 12-month intervals decreased the rates to 3.0%, 7.9%, and 13.0%, respectively. The high false-positive rates of CT (20%) and PET/CT (9%) resulted in overall low positive predictive values. However, both CT and PET/CT effectively predicted absence of disease. Life-expectancy gains were minimal (≤ 2 months) for all groups.

CONCLUSIONS

The effectiveness of routine surveillance imaging for detecting treatable melanoma recurrences is limited. Even in patients with stage III disease, only minimal gains in life expectancy were achieved.
