I COUGHIMPORTANCE: Postoperative pulmonary complications can be a devastating consequence of surgery. Validated strategies to reduce these adverse outcomes are needed. OBJECTIVES: To design, implement, and determine the efficacy of a suite of interventions for reducing postoperative pulmonary complications. DESIGN: A before-after trial comparing our National Surgical Quality Improvement Program (NSQIP) pulmonary outcomes before and after implementing I COUGH, a multidisciplinary pulmonary care program. SETTING: An urban, academic, safety-net hospital. PARTICIPANTS: All patients who underwent general or vascular surgery at our institution during a 1-year period before and after implementation of I COUGH. INTERVENTIONS: A multidisciplinary team developed a strategy to reduce pulmonary complications based on comprehensive patient and family education and a set of standardized electronic physician orders to specify early postoperative mobilization and pulmonary care. Designated by the acronym I COUGH, the program emphasizes incentive spirometry, coughing and deep breathing, oral care (brushing teeth and using mouthwash twice daily), understanding (patient and family education), getting out of bed at least 3 times daily, and head-of-bed elevation. Nursing and physician education promoted a culture of mobilization and I COUGH interventions. I COUGH was implemented for all general surgery and vascular surgery patients at our institution in August 2010. MAIN OUTCOMES AND MEASURES: The NSQIP-reported incidence and risk-adjusted ratios of postoperative pneumonia and unplanned intubation, which NSQIP reports as observed-expected (OE) ratios for the 1-year period before implementing I COUGH and as odds ratios (ORs, statistically comparable to OE ratios) for the period after its implementation. RESULTS: Before implementation of I COUGH, our incidence of postoperative pneumonia was 2.6%, falling to 1.6% after its implementation, and risk-adjusted outcomes fell from an OE ratio of 2.13 to an OR of 1.58. The incidence of unplanned intubations was 2.0% before I COUGH and 1.2% after I COUGH, with risk-adjusted outcomes decreasing from an OE ratio of 2.10 to an OR of 1.31. CONCLUSIONS AND RELEVANCE: I COUGH, a standardized postoperative care program emphasizing patient education, early mobilization, and pulmonary interventions, reduced the incidence of postoperative pneumonia and unplanned intubation among our patients.
Optimization of a Spherical Mechanism for a Minimally Invasive Surgical Robot: Theoretical and Experimental ApproachesMitchell J. H. Lum, Jennifer E. Rosen, Mika Sinanan et al.|IEEE Transactions on Biomedical Engineering|2006 With a focus on design methodology for developing a compact and lightweight minimally invasive surgery (MIS) robot manipulator, the goal of this study is progress toward a next-generation surgical robot system that will help surgeons deliver healthcare more effectively. Based on an extensive database of in-vivo surgical measurements, the workspace requirements were clearly defined. The pivot point constraint in MIS makes the spherical manipulator a natural candidate. An experimental evaluation process helped to more clearly understand the application and limitations of the spherical mechanism as an MIS robot manipulator. The best configuration consists of two serial manipulators in order to avoid collision problems. A complete kinematic analysis and optimization incorporating the requirements for MIS was performed to find the optimal link lengths of the manipulator. The results show that for the serial spherical 2-link manipulator used to guide the surgical tool, the optimal link lengths (angles) are (60 degrees, 50 degrees). A prototype 6-DOF surgical robot has been developed and will be the subject of further study.
Prophylactic Central Compartment Neck Dissection in Papillary Thyroid Cancer and Effect on Locoregional RecurrenceUnderstanding the Role of the Professional Practice Environment on Quality of Care in Magnet® and Non-Magnet HospitalsOBJECTIVE: The aim of this study was to explore the relationship between Magnet RecognitionA and nurse-reported quality of care. BACKGROUND: MagnetA hospitals are recognized for nursing excellence and quality patient outcomes; however, few studies have explored contributing factors for these superior outcomes. METHODS: This was a secondary analysis of linked nurse survey data, hospital administrative data, and a listing of American Nurses Credentialing Center Magnet hospitals. Multivariate regressions were modeled before and after propensity score matching to assess the relationship between Magnet status and quality of care. A mediation model assessed the indirect effect of the professional practice environment on quality of care. RESULTS: Nurse-reported quality of care was significantly associated with Magnet Recognition after matching. The professional practice environment mediates the relationship between Magnet status and quality of care. CONCLUSION: A prominent feature of Magnet hospitals, a professional practice environment that is supportive of nursing, plays a role in explaining why Magnet hospitals have better nurse-reported quality of care.
Treatment Options for Graves Disease: A Cost-Effectiveness AnalysisHaejin In, Elizabeth N. Pearce, Arthur K.G. Wong et al.|Journal of the American College of Surgeons|2009 BACKGROUND: First-line treatment for Graves disease is frequently 18 months of antithyroid medication (ATM). Controversy exists concerning the next best line of treatment for patients who have failed to achieve euthyroidism; options include lifelong ATM, radioactive iodine (RAI), or total thyroidectomy (TT). We aim to determine the most cost-effective option. STUDY DESIGN: We performed a cost-effectiveness analysis comparing these different strategies. Treatment efficacy and complication data were derived from a literature review. Costs were examined from a health-care system perspective using actual Medicare reimbursement rates to an urban university hospital. Outcomes were measured in quality-adjusted life-years (QALY). Costs and effectiveness were converted to present values; all key variables were subjected to sensitivity analysis. RESULTS: TT was the most cost-effective strategy, resulting in a gain of 1.32 QALYs compared with RAI (at an additional cost of $9,594) and an incremental cost-effectiveness ratio of $7,240/QALY. RAI was the least costly option at $23,600 but also provided the least QALY (25.08 QALY). Once the cost of TT exceeds $19,300, the incremental cost-effectiveness ratio of lifelong ATM and TT reverse and lifelong ATM becomes the more cost-effective strategy at $15,000/QALY. CONCLUSIONS: This is the first formal cost-effectiveness study in the US of the optimal treatment for patients with Graves disease who fail to achieve euthyroidism after 18 months of ATM. Our findings demonstrate that TT is more cost effective than RAI or lifelong ATM in these patients; this continues until the cost of TT becomes > $19,300.
