AbstractBackgroundCompare the cost-effectiveness of 2 recombinant hepatitis B virus (HBV) vaccines in patients with inflammatory bowel disease (IBD).MethodsMarkov models were developed for 2 IBD cohorts: (1) 40-year-old patients prior to starting IBD treatment and (2) 40-year-old patients already receiving therapy. Cohort A received full vaccination series, cohort B had primary vaccine failure and received a vaccine booster. Two vaccines were compared: adjuvanted HEPLISAV-B and nonadjuvanted Engerix-B. Clinical probabilities of acute hepatitis, chronic hepatitis, cirrhosis, fulminant hepatic failure and death, treatment costs, and effectiveness estimates were obtained from published literature. A lifetime analysis and a US payer perspective were used. Probabilistic sensitivity analyses were performed for different hypothetical scenarios.ResultsAnalysis of cohort A showed moderate cost-effectiveness of HEPLISAV-B ($88,114 per quality-adjusted life year). Analysis of cohort B showed increased cost-effectiveness ($35,563 per quality-adjusted life year). Changing Engerix-B to HEPLISAV-B in a hypothetical group of 100,000 patients prevented 6 and 30 cases of acute hepatitis; and 4 and 5 cases of chronic hepatitis annually for cohorts A and B, respectively. It also prevented 1 and 2 cases of cirrhosis, and 1 and 2 deaths over 20 years for each cohort. Cost-effectiveness was determined by vaccination costs, patient age, and progression rate from chronic hepatitis to cirrhosis.ConclusionsHEPLISAV-B is cost-effective over Engerix-B in patients receiving immunosuppressive therapy for IBD. Benefits increase with population aging and lower costs of vaccines. We advocate measuring levels of HBV antibodies in patients with IBD and favor adjuvanted vaccines when vaccination is needed.

AbstractBackgroundAmelanotic melanoma is an extremely rare subtype of cutaneous melanoma. The tumor characteristics are still not well understood, especially for those located in the head and neck.MethodsTumor characteristics of patients diagnosed with amelanotic melanoma of the head and neck (AMHN) from January 1, 2004, to December 31, 2015, were analyzed by querying the National Cancer Database. Characteristics of AMHN were subsequently compared with common malignant melanoma of the head and neck (CMMHN).ResultsThree hundred and sixty‐eight patients were diagnosed with AMHN, and 69,267 were diagnosed with CMMHN. Of those with AMHN, 128 (34.8%) had melanoma located on the scalp and neck, and 172 (46.7%) were diagnosed with an early disease stage (i.e., 0, I, or II). When compared with CMMHN, patients with AMHN were more likely to be diagnosed after 80 years of age (25.3% vs. 18.2%; odds ratio [OR], 3.28; 95% CI, 1.09–9.84; P = 0.03), when Breslow depth was between 2.01 and 4.00 mm (28.5% vs. 6.5%; OR, 1.92; 95% CI, 1.15–3.19; P = 0.01), when ulceration was present (36.7% vs. 9.0%; OR, 1.99; 95% CI, 1.34–2.97; P = 0.001), and when mitotic count was 1 or more/mm2 (40.5% vs. 12.8%; OR; 2.53; 95% CI, 1.09–5.89; P = 0.03). No statistical difference was found for sex, specific location, stage, or lymph node involvement.ConclusionOur study determined that AMHN is associated with older age, increased Breslow depth, presence of ulceration, and greater mitotic count when compared with CMMHN.

Background: US hospitals are penalized for excess 30-day readmissions and mortality for select conditions. Under the Centers for Medicare and Medicaid Services policy, readmission prevention is incentivized to a greater extent than mortality reduction. A strategy to potentially improve hospital performance on either measure is by improving nursing care, as nurses provide the largest amount of direct patient care. However, little is known as to whether achieving nursing excellence, such as Magnet status, is associated with improved hospital performance on readmissions and mortality. Objective: The purpose of this study was to examine the relationship between hospitals’ Magnet status and performance on readmission and mortality rates for Medicare beneficiaries. Research Design: This is a cross-sectional analysis of Medicare readmissions and mortality reduction programs from 2013 to 2016. A propensity score–matching approach was used to take into account differences in baseline characteristics when comparing Magnet and non-Magnet hospitals. Subjects: The sample was comprised of 3877 hospitals. Measures: The outcome measures were 30-day risk-standardized readmission and mortality rates. Results: Following propensity score matching on hospital characteristics, we found that Magnet hospitals outperformed non-Magnet hospitals in reducing mortality; however, Magnet hospitals performed worse in reducing readmissions for acute myocardial infarction, coronary artery bypass grafting, and stroke. Conclusions: Magnet hospitals performed better on the Hospital Value-Based Purchasing Mortality Program than the Hospital Readmissions Reduction Program. The results of this study suggest the need for The Magnet Recognition Program to examine the role of nurses in postdischarge activities as a component of its evaluation criteria.

BACKGROUND: Paget’s disease of the breast is rare. The National Cancer Database (NCDB) is one of the largest tumor databases in the United States. METHODS: We queried the NCDB to identify male and female patients with Paget’s disease of the breast who were treated from January 1, 2004, through December 31, 2015. No age limitations were applied. Descriptive statistical analysis and survival analysis were performed. RESULTS: We analyzed the demographic, disease, and treatment characteristics of 7,191 patients with Paget’s disease of the breast. The median (range) age was 64 (20–90) years. Only 2.1% of patients were men, and 85.4% were white. The most common treatment was complete mastectomy (65.3%), followed by partial mastectomy (30.3%). Tumor destruction was performed in 0.1% of patients, and 4.3% of patients did not undergo any surgery. We examined survival in the subset of 6,864 patients who were treated surgically with complete mastectomy or partial mastectomy. The 5-year survival rate after surgery was 82.5% (95% CI, 81.1%–83.9%). Factors associated with shorter survival were older age, black race/ethnicity, higher tumor grade, regional lymph node metastasis, higher cancer stage, metastatic cancer, and larger tumor size. CONCLUSIONS: Paget’s disease of the breast usually affects patients older than 60 years, and the most common treatment is complete mastectomy. The 5-year overall survival rate of patients with Paget’s disease of the breast is greater than 80% but is lower among older and black people.

Background Artificial Intelligent Virtual Assistants (AIVA) is a segment of artificial intelligence that is rapidly developing. However, its utilization to address patients' frequently asked questions remains unexplored. Methods We developed an AIVA to answer questions related to 10 frequent topics asked by plastic surgery patients in our institution. Between July 27, 2018, and August 10 of 2018, we recruited subjects with administrative positions at our health care institution to chat with the virtual assistant. They asked, with their own words, 1 question for each topic and filled out a satisfaction questionnaire. Postsurvey analysis of questions and answers allowed assessment of the virtual assistant's accuracy. Results Thirty participants completed the survey. The majority was female (70%), and the mean age was 27.76 years (SD, 8.68 [19–51] years). The overall accuracy of the plastic surgery AIVA was 92.3% (277/294 questions), and participants considered the answer correct in 83.3% of the time (250/294 answers). Most of the participants considered the AIVA easy to use, answered adequately, and could be helpful for patients. However, when asked if this technology could replace a human assistant, they stayed neutral.

Background Microsurgery is one of the most complex operative skills. Recent restrictions on residents’ working hours challenge residency program directors to ensure skill acquisition with scant time dedicated to microsurgery practice. We aimed to summarize the contribution of plastic surgery journals in microsurgical education. Methods A comprehensive literature search was performed. Results We observed an increasing number of publications on microsurgery education over the years. This could be due to the adoption of new technologies developed in the last 2 decades, the concerns about quality of resident training in the context of reduced work hours, the well-described benefit of medical simulations in other specialties, and the pressure on trainees to be proficient before operating on patients. The variety of aspects addressed in plastic surgery publications is broad: simulators, courses, skills assessment, national surveys, and technology trends. Conclusion There is an upward trend in the number of publications and plastic surgery journals, demonstrating a remarkable contribution to microsurgery training.

Hospitals are expected to fulfill a role in the communities they serve by improving the health of the population in the community as mandated in the Affordable Care Act. One way hospitals achieve this is to create partnerships with diverse organizations, such as local public health departments, state/federal agencies, and other health care organizations. The aim of this study is to examine characteristics of hospitals that developed partnerships based on improving population health. This study utilized the 2015 Population Health Survey, American Hospital Association Database, and Dartmouth Atlas of Health Care. Hospital characteristics included size, ownership status, part of a system, teaching status location, Medicare percentage, Medicaid percentage, average stay length, and inpatient days per 1000 persons. Level of partnership was measured by the hospital's current working relationship with other hospitals/health care systems or local/state/other agencies. Univariate, bivariate, and multivariate regression analyses were used to analyze the relationship between hospital partnerships and organizational characteristics. Hospitals with strong relationships tend to be larger and not-for-profit hospitals, hospitals with system members and located in urban areas, and teaching-affiliated hospitals. This study also found hospital characteristics were related to hospitals' partnerships. Hospitals within health care systems and with high inpatient volume were more likely to report relationships that were stronger. This study provides a systematic and updated look at hospitals' partnership when looking at commitment to population health improvement and contributes to the literature by informing about the greater need to support rural and smaller hospitals with population health outreach activities.

ABSTRACT Background and purpose: Daily chest radiographs (CXRs) have long been a routine part of care. However, evidence as well as changing technology has promoted on-demand CXRs as beneficial to patient care. We found that a substantial number of routine daily CXRs were being ordered, with some of the orders staying active even after extubation. Methods: Within a 19-bed adult medical ICU, we prospectively utilized 3 intervention phases from October 1, 2014, to February 28, 2018, to reduce routine CXRs. Nurse Practitioners (NP) initiated this quality improvement (QI) project, aiming to reduce the number of unnecessary of CXRs. Interventions included staff survey, routine CXR order removal, duplicate alerts, visual reminders, and an electronic clinical decision support tool. Monthly education of appropriate CXRs and bedside ultrasound were facilitated by NPs. The outcome measures of interest include: the number of CXRs per patient-day, the number of routine and on-demand CXRs, mortality rate, ICU length of stay, and ventilator days, radiation and cost. Conclusions: Total number of CXRs per patient-day decreased by 36.1%. The proportion of routine CXRs decreased from 55.37% to 13.18%; on-demand orders increased, from 44.63% to 86.82%; and calculated radiation-exposure per census decreased, from 0.011 to 0.008 mSv. In addition, charges to patients for CXRs decreased by $7,750/month. ICU mortality and ventilator days per census remained stable. Implications for practice: By an orchestrated process that included creating awareness and desire to change CXR ordering practices, we were able to decrease routine CXRs and increase on-demand utilization while maintaining counterbalance measures.

Abstract Background: Laparoscopy and more recently robotics are increasingly used for colorectal cancer surgery in the United States. We examined the current trends of minimally invasive surgical resections for colorectal cancer in Florida. Methods: The Florida Inpatient Discharge Dataset was used to examine the clinical data of patients who underwent elective surgery for colorectal cancer during 2013–2015. Multivariate analyses were performed to compare patient characteristics associated with the use of open and minimally invasive surgeries. Results: A total of 10,513 patients were analyzed; 5451 (52%) had open surgery, 4403 (42%) laparoscopy, and 659 (6%) robotic surgery. The rates of minimally invasive surgery (MIS) increased from 46.95% in 2013 to 48.72% in 2015. Among minimally invasive surgical procedures, the use of robotics increased from 9.82% in 2013 to 15.48% in 2015. Metastatic cancer (odds ratio [OR] 0.61, confidence interval [CI] 0.55–0.67), Elixhauser score of 3–5 (OR 0.85, CI 0.76–0.95) or more than 5 (OR 0.78, CI 0.63–0.97), Medicaid insurance (OR 0.73, CI 0.6–0.89), Black race (OR 0.88, CI 0.77–0.99), and rural residence (OR 0.83, CI 0.69–0.99) were associated with lower odds of MIS than open surgery. Conclusions: This study demonstrates that the overall rates of MIS for colorectal cancer in Florida increased from 2013 to 2015. Socially deprived and very sick patient populations with colorectal cancer are less likely to undergo MIS.
