Comparative Assessment of Ergonomic Experience with Heads-Up Display and Conventional Surgical Microscope in the Operating Room.

PURPOSE: Musculoskeletal pain issues are prevalent in ophthalmic surgeons and can impact surgeon well-being and productivity. Heads-up displays (HUD) can improve upon conventional microscopes by reducing ergonomic stress. This study compared ergonomic outcomes between HUD and a conventional optical microscope in the operating room, as reported by ophthalmic surgeons in the US. METHODS: An online questionnaire was distributed to a sample of surgeons who had experience operating with HUD. The questionnaire captured surgeon-specific variables, the validated Nordic Musculoskeletal Questionnaire, and custom questions to compare HUD and conventional microscope. A multivariable model was built to identify variables that were likely to predict improvement in pain-related issues. RESULTS: Analysis was conducted on 64 surgeons (37 posterior-segment, 25 anterior-segment, and two mixed) with a mean 14.9 years of practice and 2.3 years using HUD. Most surgeons agreed or strongly agreed that HUD reduced the severity (64%) and frequency (63%) of pain and discomfort, improved posture (73%), and improved overall comfort (77%). Of respondents who experienced headaches, or pain and discomfort during operation, 12 (44%) reported their headaches improved and 45 (82%) reported feeling less pain and discomfort since they started using HUD. The multivariable model indicated the odds of reporting an improvement in pain since introducing the HUD in the operating room were 5.12-times greater for those who used HUD in >50% of their cases (P=0.029). CONCLUSION: This study indicates that heads-up display may be an important tool for wellness in the operating room as it can benefit ophthalmic surgeons across several ergonomic measures.

Health economic impact of first-pass success among patients with acute ischemic stroke treated with mechanical thrombectomy: a United States and European perspective.

BACKGROUND: First-pass effect (FPE), restoring complete or near complete reperfusion (modified Thrombolysis in Cerebral Infarction (mTICI) 2c-3) in a single pass, is an independent predictor for good functional outcomes in the endovascular treatment of acute ischemic stroke. The economic implications of achieving FPE have not been assessed. OBJECTIVE: To assess the economic impact of achieving complete or near complete reperfusion after the first pass. METHODS: Post hoc analyses were conducted using ARISE II study data. The target population consisted of patients in whom mTICI 2c-3 was achieved, stratified into two groups: (1) mTICI 2c-3 achieved after the first pass (FPE group) or (2) after multiple passes (non-FPE group). Baseline characteristics, clinical outcomes, and healthcare resource use were compared between groups. Costs from peer-reviewed literature were applied to assess cost consequences from the perspectives of the United States (USA), France, Germany, Italy, Spain, Sweden, and United Kingdom (UK). RESULTS: Among patients who achieved mTICI 2c-3 (n=172), FPE was achieved in 53% (n=91). A higher proportion of patients in the FPE group reached good functional outcomes (90-day modified Rankin Scale score 0-2 80.46% vs 61.04%, p<0.01). The patients in the FPE group had a shorter mean length of stay (6.10 vs 9.48 days, p<0.01) and required only a single stent retriever, whereas 35% of patients in the non-FPE group required at least one additional device. Driven by improvement in clinical outcomes, the FPE group had lower procedural/hospitalization-related (24-33% reduction) and annual care (11-27% reduction) costs across all countries. CONCLUSIONS: FPE resulted in improved clinical outcomes, translating into lower healthcare resource use and lower estimated costs.

A budget impact analysis of a magnetic sphincter augmentation device for the treatment of medication-refractory mechanical gastroesophageal reflux disease: a United States payer perspective.

BACKGROUND: Medication-refractory gastroesophageal reflux disease (GERD) is sometimes treated with laparoscopic Nissen fundoplication (LNF); however, this is a non-reversible procedure associated with important side effects and the need for repeat surgery. Removable magnetic sphincter augmentation (MSA) devices are an alternative, effective, and safe treatment option for such patients who have some lower esophageal sphincter function. The objective of this study was to assess the economic impact of introducing MSA technology (i.e., LINX Reflux Management System) into current practice from a US-payer perspective. METHODS: An economic budget impact model was developed over a 1-year time horizon that compared current treatment of GERD patients who are medically managed (but refractory) or receiving LNF to future treatment of GERD patients that included a mix of patients treated with medical management only, LNF, or MSA. Resources included within the analyses were index procedures (inpatient and outpatient use), reoperations (revisions and removals), readmissions, healthcare visits, diagnostic tests, procedures, and medications. Medicare payment rates were typically used to inform unit costs. RESULTS: Assuming a hypothetical commercial insurance population of 1 million members, the base-case analysis estimated a net cost savings of $111,367 with introduction of the MSA. This translates to a savings of $0.01 per member per month. Results were largely driven by avoided inpatient procedures with use of the MSA device. Alternative analyses exploring the potential impact of increasing surgical volumes predicted that results would remain cost saving if the proportion of MSA market share taken from LNF was ≥ 90%. CONCLUSIONS: This study predicts that the introduction of the MSA device would lead to favorable budget impact results for the treatment of medication-refractory mechanical GERD for commercial payers. Future analyses will benefit from inclusion of middle-ground treatments as well as longer time horizons.

Procedure costs associated with the use of Harmonic devices compared to conventional techniques in various surgeries: a systematic review and meta-analysis.

BACKGROUND: As compared to conventional techniques, recent meta-analyses have reported cost savings with Harmonic devices; however, only in thyroidectomy. Thus, the aim of this study was to evaluate the costs associated with Harmonic devices versus conventional techniques across a range of surgical procedures. METHODS: A systematic search of MEDLINE, EMBASE, and Cochrane Library was conducted from inception to October 01, 2016 without language restrictions to identify randomized controlled trials comparing Harmonic devices to conventional techniques and reporting procedure costs (operating time plus operating equipment/consumables/device costs). Costs were pooled using the ratio of geometric means, and a random effects model was applied. Sensitivity analyses varying statistical methods, number of included studies, and cost outcomes were completed to test the robustness of the results. RESULTS: Thirteen studies met the inclusion criteria. A total of 561 and 540 participants had procedures performed with Harmonic devices and conventional methods, respectively, with procedures including gastrectomy, thyroidectomy, colectomy, cholecystectomy, Nissen fundoplication, and pancreaticoduodenectomy. As compared to conventional methods, Harmonic devices reduced total procedure costs by 8.7% (p=0.029), resulting in an absolute reduction of US$227.77 from mean conventional technique costs, derived primarily from a reduction in operating time costs. When operating time costs, excluding operating equipment/consumables/device costs, were analyzed, costs were reduced by $544 per procedure with the use of Harmonic devices. The results from all sensitivity analyses demonstrated cost reductions with Harmonic devices. CONCLUSION: This systematic review and meta-analysis showed that despite a higher device cost, Harmonic devices provide a statistically significant reduction in procedure costs, derived primarily from a reduction in operating time costs, across surgical procedures. In addition to functionality benefits, Harmonic devices may represent a potentially cost saving method to reduce overall hospital resource use. Future research should focus on potential costs and benefits from use of Harmonic devices in procedures not covered here.
