RESUMO

INTRODUCTION: Some for-profit businesses act like non-profit anchor institutions in contributing to community development, particularly health-related initiatives. Their motives are not well understood. We aimed to 1) identify and describe potential anchor businesses, 2) determine their motivations to contribute to community development, and 3) highlight motivations behind health-related initiatives. MATERIALS AND METHODS: We identified a national sample of potential anchor businesses, grouped by those that contributed to 1) both health-related and non-health initiatives, 2) non-health initiatives only, and 3) those without substantial contributions. We conducted an environmental scan, semi-structured qualitative interviews and directed content analysis through rapid review methodology. RESULTS: We identified 4,512 potential anchor businesses nationally. Among the 108 of these included in the environmental scan, 48% substantially contributed to community development (12% in health). Interviewees' company philosophies ranged from the idea that economic well-being of the company and community were intertwined, to the idea that commercial success of the company would benefit the community. Motivations for contributions included improving the hiring pool, improved recruitment and retention, and goodwill. Other common sentiments included strategies to focus on core business strengths to address community needs and a desire that companies should not compete in their giving activities. Further, some participants believed health care companies should be investing in health-related initiatives. CONCLUSIONS: The generosity of potential anchor businesses' local contributions may be determined by company philosophy about its relationship with the community. Stakeholders interested in spurring contributions to local communities might consider messaging to leverage businesses' core strengths and encourage cooperation.

RESUMO

Three denitrifying bacteria, Paracoccus spp., Thauera spp., Pseudomonas-like spp., and two functional genes, nitrate reductase (narG and napA), were studied as potential biomarkers for total nitrogen removal. These bacterial genera and the functional genes showed significant negative correlations with total nitrogen in the effluent (TNeff). Thauera spp. had the highest correlation (r = -0.793, p < 0.001) with TNeff, and narG-like and napA genes also showed significant correlations (r = -0.663 and -0.643, respectively), suggesting functional genes have equal validity to 16S rRNA genes in monitoring denitrification performance. The most explanatory variables were a combination of constituents, with temperature emerging as the most important in Pearson's correlation and redundancy analysis. Thauera spp. had the highest correlation with temperature (r = 0.739) followed closely by Paracoccus spp. (r = 0.705). Denitrification was also significantly affected by pH (r = 0.369), solids retention time (r = -0.377), total nitrogenin (r = 0.635), and organic matter in the influent (biochemical oxygen demand and chemical oxygen demand; r = 0.320 and 0.522, respectively). Our data verified that major denitrifiers' 16S rRNA genes and nitrate reductase genes were better biomarkers than the biomass concentration, and any of the biomarkers could track denitrification in real time.

RESUMO

BACKGROUND: Given the widespread electronic health record adoption, there is increasing interest to leverage patient portals to improve care. OBJECTIVE: To determine characteristics of patient portal users and the activities they accessed in the patient portal. METHODS: We performed a retrospective analysis of patient portal usage at University of California, Los Angeles, Health from July 2014 to May 2015. A total dataset of 505,503 patients was compiled with 396,303 patients who did not register for the patient portal and 109,200 patients who registered for a patient portal account. We compared patients who did not register for the online portal to the top 75th percentile of users based on number of logins, which was done to exclude those who only logged in to register. Finally, to avoid doing statistical analysis on too large of a sample and overpower the analysis, we performed statistical tests on a random sample of 300 patients in each of the two groups. RESULTS: Patient portal users tended to be older (49.45 vs. 46.22 years in the entire sample, p = 0.008 in the random sample) and more likely female (62.59 vs. 54.91% in the entire sample, p = 0.035 in the random sample). Nonusers had more monthly emergency room (ER) visits on average (0.047 vs. 0.014, p < 0.001). The most frequently accessed activity on the portal was viewing laboratory results (79.7% of users looked at laboratory results). CONCLUSION: There are differences between patient portal users and nonusers, and further understanding of these differences can serve as foundation for further investigation and possible interventions to drive patient engagement and health outcomes.

RESUMO

BACKGROUND: Clinic no shows (NS) create a lost opportunity for provider-patient interaction and impose a financial burden to the healthcare system and on society. We aimed to: (1) to determine the clinical and demographic factors associated with increased NS rates at a children's hospital's subsubspecialty clinics and (2) to estimate the direct institutional financial costs associated with NS events. METHODS: A comprehensive database was generated from all clinic encounters for 15 subspecialty outpatient clinics (five surgical and 10 medical) between September 12, 2005 and December 30, 2010. Multivariate logistic regressions were performed to identify the variables associated with NS events. Direct costs of NS events were estimated using annual revenue for each clinic. RESULTS: A total of 284,275 encounters and 17,024 NS events were available for analysis. Public insurance coverage (Medicaid and Title V), compared to private insurance or self-pay status, was associated with an increased likelihood NS (OR 2.19, 95% CI 2.10-2.28, p < 0.0005 for Medicaid; OR 1.56, 95% CI 1.50-1.62, p < 0.0005 for Title V). Compared to patients 21-30 years of age, patients <12 years (OR 2.08, 95% CI 1.77-2.45, p < 0.0005) had increased likelihood of NS. Scheduled visits with medical subspecialists were more likely than surgical subspecialty visits to result in a NS (OR 1.69, 95% CI 1.63-1.75, p < 0.0005). The predicted annualized lost revenue associated with NS visits was estimated at $730,000 from the 15 clinics analyzed, approximately $210 per NS event. CONCLUSION: Pediatric subspecialty NS events are common, costly, and potentially preventable.

RESUMO

BACKGROUND & AIMS: Patients with asymptomatic or poorly managed celiac disease can experience bone loss, placing them at risk for hip and vertebral fractures. We analyzed the cost-effectiveness of universal serologic screening (USS) vs symptomatic at-risk screening (SAS) strategies for celiac disease because of the risk of nontraumatic hip and vertebral fractures if untreated or undiagnosed. METHODS: We developed a lifetime Markov model of the screening strategies, each with male or female cohorts of 1000 patients who were 12 years old when screening began. We screened serum samples for levels of immunoglobulin A, compared with tissue transglutaminase and total immunoglobulin A, and findings were confirmed by mucosal biopsy. Transition probabilities and quality of life estimates were obtained from the literature. We used generalizable cost estimates and Medicare reimbursement rates and ran deterministic and probabilistic sensitivity analyses. RESULTS: For men, the average lifetime costs were $8532 and $8472 for USS and SAS strategies, respectively, corresponding to average quality-adjusted life year gains of 25.511 and 25.515. Similarly for women, costs were $11,383 and $11,328 for USS and SAS strategies, respectively, corresponding to quality-adjusted life year gains of 25.74 and 25.75. Compared with the current standard of care (SAS), USS produced higher average lifetime costs and lower quality of life for each sex. Deterministic and probabilistic sensitivity analyses showed that the model was robust to realistic changes in all the variables, making USS cost-ineffective on the basis of these outcomes. CONCLUSIONS: USS and SAS are similar in lifetime costs and quality of life, although the current SAS strategy was overall more cost-effective in preventing bone loss and fractures among patients with undiagnosed or subclinical disease. On the basis of best available supportive evidence, it is more cost-effective to maintain the standard celiac screening practices, although future robust population-based evidence in other health outcomes could be leveraged to reevaluate current screening guidelines.

RESUMO

BACKGROUND: Inflammatory bowel diseases are costly chronic gastrointestinal diseases. We aimed to determine whether immediate colectomy with ileal pouch-anal anastamosis (IPAA) after diagnosis of severe ulcerative colitis (UC) was cost-effective compared to the standard medical therapy. METHODS: We created a Markov model simulating 2 cohorts of 21-year-old patients with severe UC, following them until 100 years of age or death, comparing early colectomy with IPAA strategy to the standard medical therapy strategy. Deterministic and probabilistic analyses were performed. RESULTS: Standard medical care accrued a discounted lifetime cost of $236,370 per patient. In contrast, early colectomy with IPAA accrued a discounted lifetime cost of $147,763 per patient. Lifetime quality-adjusted life-years gained (QALY-gained) for standard medical therapy was 20.78, while QALY-gained for early colectomy with IPAA was 20.72. The resulting incremental cost-effectiveness ratio (Δcosts/ΔQALY) was approximately $1.5 million per QALY-gained. Results were robust to one-way sensitivity analyses for all variables in the model. Quality-of-life after colectomy with IPAA was the most sensitive variable impacting cost-effectiveness. A low utility value of less than 0.7 after colectomy with IPAA was necessary for the colectomy with IPAA strategy to be cost-ineffective. CONCLUSIONS: Under the appropriate clinical settings, early colectomy with IPAA after diagnosis of severe UC reduces health care expenditures and provides comparable quality of life compared to exhaustive standard medical therapy.

RESUMO

BACKGROUND: Inflammatory bowel diseases (IBDs) are costly chronic gastrointestinal diseases, with pediatric IBD representing increased costs per patient compared to adult disease. Health care expenditures for ulcerative colitis (UC) are >$2 billion annually. It is not clear whether the addition of VSL#3 to standard medical therapy in UC induction and maintenance of remission is a cost-effective strategy. PATIENTS AND METHODS: We performed a systematic review of the literature and created a Markov model simulating a cohort of 10-year-old patients with severe UC, studying them until 100 years of age or death. We compared 2 strategies: standard medical therapy versus medical therapy + VSL#3. For both strategies, we assumed that patients progressed through escalating therapies--mesalamine, azathioprine, and infliximab--before receiving a colectomy + ileal pouch anal anastamosis (IPAA) if the 3 medical therapy options were exhausted. The primary outcome measure was the incremental cost-effectiveness ratio (ICER), defined as the difference of costs between strategies for each quality-adjusted life-year (QALY) gained. One-way sensitivity analyses were performed on variables to determine the key variables affecting cost-effectiveness. RESULTS: Standard medical care accrued a lifetime cost of $203,317 per patient, compared to $212,582 per patient for medical therapy + VSL#3. Lifetime QALYs gained was comparable for standard medical therapy and medical therapy + VSL#3 at 24.93 versus 25.05, respectively. Using the definition of ICER <50,000/QALY as a cost-effective intervention, medical therapy + VSL#3 produced an ICER of $79,910 per QALY gained, making this strategy cost-ineffective. Sensitivity analyses showed that 4 key parameters could affect the cost-effectiveness of the 2 strategies: cost of colectomy + IPAA, maintenance cost after surgery, probability of developing pouchitis after surgery, and the quality of life after a colectomy + IPAA. High surgical and postsurgical costs, a high probability of developing pouchitis, and a low quality of life after a colectomy + IPAA could make adjunct VSL#3 use a cost-effective strategy. CONCLUSIONS: Given present data, adjunct VSL#3 use for pediatric UC induction and maintenance of remission is not cost-effective, although several key parameters could make this strategy cost-effective. The quality of life after an IPAA is the single most important variable predicting whether this procedure benefits patients over escalating standard medical therapy.

RESUMO

We report on a novel optical thin film material, erbium-doped deuterated amorphous carbon, fabricated directly on silicon substrate at room-temperature via controlled thermal evaporation of a Metal-Organic compound in a Plasma-Enhanced Chemical Vapour Deposition (MO-PECVD) system. High erbium concentrations (up to 2.3 at.%) and room-temperature photoluminescence at 1.54 microm are successfully demonstrated. Concentration quenching due to erbium clustering is reduced by adopting an appropriate MO precursor-Er(tmhd)(3). Another quenching mechanism, caused by non-radiative C-H and O-H vibrational transitions, is shown for the first time to be significantly reduced by deuteration instead of hydrogenation of amorphous carbon. Our results suggest that erbium-doped deuterated amorphous carbon is a promising new class of photonic material for silicon-compatible optoelectronics applications in the technologically important 1.5microm wavelength region.
