RESUMEN

BACKGROUND: The Centers for Medicare and Medicaid Services (CMS) implemented the Medicare durable medical equipment (DME) Competitive Bidding Program (CBP) in 2011. Since then, concerns have been raised regarding access to equipment and adverse health outcomes. OBJECTIVES: The aim was to evaluate whether the CBP was associated with changes in spending, utilization, and adverse health events (emergency department visits, hospitalizations, and falls). RESEARCH DESIGN: A comparative interrupted time series over 8 years was used to compare Round1 and Round2 bidding to nonbidding areas. Medicare fee for services claims were aggregated at the quarterly Metropolitan Statistical Area (MSA) level from 2009 to 2016. RESULTS: For the 3 evaluated DME (continuous positive airway pressure machines, oxygen supplies, and walkers), we found that implementation of the Medicare CBP was associated with reductions in per capita spending without changes in DME utilization or adverse health outcomes in CBP areas compared with nonbidding areas. For example, the slope change in the proportion of oxygen supplies purchasers in Round1 areas after implementation of Round1 was similar to the slope change in nonbidding areas (-0.0002; 95% CI: -0.0004, 0.0001; P=0.189). The difference in slope changes of emergency department visits and hospitalization in Round1 areas for oxygen supplies were (-0.0004; 95% CI: -0.0016, 0.0008; P=0.514) and (0.0002; 95% CI: -0.0010, 0.0014; P=0.757), respectively. Findings in Round2 areas after implementation of Round2 were similar to findings in Round1 areas. CONCLUSIONS: The Medicare DME CBP lowered Medicare expenditures while not reducing beneficiary access or increasing adverse outcomes.

RESUMEN

S100B, a biomarker of malignant melanoma, interacts with the p53 protein and diminishes its tumor suppressor function, which makes this S100 family member a promising therapeutic target for treating malignant melanoma. However, it is a challenge to design inhibitors that are specific for S100B in melanoma versus other S100-family members that are important for normal cellular activities. For example, S100A1 is most similar in sequence and structure to S100B, and this S100 protein is important for normal skeletal and cardiac muscle function. Therefore, a combination of NMR and computer aided drug design (CADD) was used to initiate the design of specific S100B inhibitors. Fragment-based screening by NMR, also termed "SAR by NMR," is a well-established method, and was used to examine spectral perturbations in 2D [1H, 15N]-HSQC spectra of Ca2+-bound S100B and Ca2+-bound S100A1, side-by-side, and under identical conditions for comparison. Of the 1000 compounds screened, two were found to be specific for binding Ca2+-bound S100A1 and four were found to be specific for Ca2+-bound S100B, respectively. The NMR spectral perturbations observed in these six data sets were then used to model how each of these small molecule fragments showed specificity for one S100 versus the other using a CADD approach termed Site Identification by Ligand Competitive Saturation (SILCS). In summary, the combination of NMR and computational approaches provided insight into how S100A1 versus S100B bind small molecules specifically, which will enable improved drug design efforts to inhibit elevated S100B in melanoma. Such a fragment-based approach can be used generally to initiate the design of specific inhibitors for other highly homologous drug targets.

RESUMEN

OBJECTIVES: Procurement's important role in healthcare decision making has encouraged criticism and calls for greater collaboration with health technology assessment (HTA), and necessitates detailed analysis of how procurement approaches the decision task. METHODS: We reviewed tender documents that solicit medical technologies for patient care in Canada, focusing on request for proposal (RFP) tenders that assess quality and cost, supplemented by a census of all tender types. We extracted data to assess (i) use of group purchasing organizations (GPOs) as buyers, (ii) evaluation criteria and rubrics, and (iii) contract terms, as indicators of supplier type and market conditions. RESULTS: GPOs were dominant buyers for RFPs (54/97) and all tender types (120/226), and RFPs were the most common tender (92/226), with few price-only tenders (11/226). Evaluation criteria for quality were technical, including clinical or material specifications, as well as vendor experience and qualifications; "total cost" was frequently referenced (83/97), but inconsistently used. The most common (47/97) evaluative rubric was summed scores, or summed scores after excluding those below a mandatory minimum (22/97), with majority weight (64.1 percent, 62.9 percent) assigned to quality criteria. Where specified, expected contract lengths with successful suppliers were high (mean, 3.93 years; average renewal, 2.14 years), and most buyers (37/42) expected to award to a single supplier. CONCLUSIONS: Procurement's evaluative approach is distinctive. While aiming to go beyond price in the acquisition of most medical technologies, it adopts a narrow approach to assessing quality and costs, but also attends to factors little considered by HTA, suggesting opportunities for mutual lesson learning.

RESUMEN

Treatment of hemophilia consists of replacement of the missing coagulation factor, either prophylactically or at the time of injury or bleeding. Because of the high cost of these products, which can present a barrier to care, different procurement strategies have been developed at national and regional levels. The emergence of novel therapeutic agents adds complexity to these strategies. This paper examines the benefits and challenges of these strategies, with primary reference to the Canadian context and a consideration of the concepts of value-based care.

RESUMEN

BACKGROUND: The long-term effect of an antimicrobial stewardship program (ASP) and its integrated impact with competitive biddings have been seldom reported. AIM: To evaluate the long-term effect of an ASP on antimicrobial consumption, expenditure, antimicrobial resistance and hospital mortality. To estimate the contribution of competitive biddings on cost-savings. MATERIAL AND METHODS: A comparison of periods prior (2005-2008) and posterior to ASP initiation (2009 and 2015) was done. An estimation of cost savings attributable to ASP and to competitive biddings was also performed. RESULTS: Basal median antimicrobial consumption decreased from 221.3 to 170 daily defined doses/100 beds after the start of the ASP. At the last year, global antimicrobial consumption declined by 28%. Median antimicrobial expenditure per bed (initially US$ 13) declined to US$ 10 at the first year (-28%) and to US$ 6 the last year (-57%). As the reduction in consumption was lower than the reduction in expenditure during the last year, we assumed that only 48.4% of savings were attributable to the ASP. According to antimicrobial charges per bed from prior and after ASP implementation, we estimated global savings of US$ 393072 and US$ 190000 directly attributable to the ASP, difference explained by parallel competitive biddings. Drug resistance among nosocomial bacterial isolates did not show significant changes. Global and infectious disease-associated mortality per 1000 discharges significantly decreased during the study period (p < 0.05). CONCLUSIONS: The ASP had a favorable impact on antimicrobial consumption, savings and mortality rates but did not have effect on antimicrobial resistance in selected bacterial strains.

RESUMEN

BACKGROUND: Fenestrated endovascular aneurysm repair (FEVAR) allows endovascular treatment of thoracoabdominal and juxtarenal aneurysms previously outside the indications of use for standard devices. However, because of considerable device costs and increased procedure time, FEVAR is thought to result in financial losses for medical centers and physicians. We hypothesized that surgeon leadership in the coding, billing, and contractual negotiations for FEVAR procedures will increase medical center contribution margin (CM) and physician reimbursement. METHODS: At the UMass Memorial Center for Complex Aortic Disease, a vascular surgeon with experience in medical finances is supported to manage the billing and coding of FEVAR procedures for medical center and physician reimbursement. A comprehensive financial analysis was performed for all FEVAR procedures (2011-2015), independent of insurance status, patient presentation, or type of device used. Medical center CM (actual reimbursement minus direct costs) was determined for each index FEVAR procedure and for all related subsequent procedures, inpatient or outpatient, 3 months before and 1 year subsequent to the index FEVAR procedure. Medical center CM for outpatient clinic visits, radiology examinations, vascular laboratory studies, and cardiology and pulmonary evaluations related to FEVAR were also determined. Surgeon reimbursement for index FEVAR procedure, related adjunct procedures, and assistant surgeon reimbursement were also calculated. All financial analyses were performed and adjudicated by the UMass Department of Finance. RESULTS: The index hospitalization for 63 FEVAR procedures incurred $2,776,726 of direct costs and generated $3,027,887 in reimbursement, resulting in a positive CM of $251,160. Subsequent related hospital procedures (n = 26) generated a CM of $144,473. Outpatient clinic visits, radiologic examinations, and vascular laboratory studies generated an additional CM of $96,888. Direct cost analysis revealed that grafts accounted for the largest proportion of costs (55%), followed by supplies (12%), bed (12%), and operating room (10%). Total medical center CM for all FEVAR services was $492,521. Average surgeon reimbursements per FEVAR from 2011 to 2015 increased from $1601 to $2480 while the surgeon payment denial rate declined from 50% to 0%. Surgeon-led negotiations with the Centers for Medicare & Medicaid Services during 2015 resulted in a 27% increase in physician reimbursement for the remainder of 2015 ($2480 vs $3068/case) and a 91% increase in reimbursement from 2011 ($1601 vs $3068). Assistant surgeon reimbursement also increased ($266 vs $764). Concomitant FEVAR-related procedures generated an additional $27,347 in surgeon reimbursement. CONCLUSIONS: Physician leadership in the coding, billing, and contractual negotiations for FEVAR results in a positive medical center CM and increased physician reimbursement.

RESUMEN

This rule updates and makes revisions to the End-Stage Renal Disease (ESRD) Prospective Payment System (PPS) for calendar year 2017. It also finalizes policies for coverage and payment for renal dialysis services furnished by an ESRD facility to individuals with acute kidney injury. This rule also sets forth requirements for the ESRD Quality Incentive Program, including the inclusion of new quality measures beginning with payment year (PY) 2020 and provides updates to programmatic policies for the PY 2018 and PY 2019 ESRD QIP. This rule also implements statutory requirements for bid surety bonds and state licensure for the Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS) Competitive Bidding Program (CBP). This rule also expands suppliers' appeal rights in the event of a breach of contract action taken by CMS, by revising the appeals regulation to extend the appeals process to all types of actions taken by CMS for a supplier's breach of contract, rather than limit an appeal for the termination of a competitive bidding contract. The rule also finalizes changes to the methodologies for adjusting fee schedule amounts for DMEPOS using information from CBPs and for submitting bids and establishing single payment amounts under the CBPs for certain groupings of similar items with different features to address price inversions. Final changes also are made to the method for establishing bid limits for items under the DMEPOS CBPs. In addition, this rule summarizes comments on the impacts of coordinating Medicare and Medicaid Durable Medical Equipment for dually eligible beneficiaries. Finally, this rule also summarizes comments received in response to a request for information related to the Comprehensive ESRD Care Model and future payment models affecting renal care.

RESUMEN

The v114* cyclic peptide has been identified as a tight vascular endothelial growth factor (VEGF) ligand. Here we report on the use of isothermal titration calorimetry (ITC), 96-well plate competition assay, and circular dichroism (CD) to explore the binding determinants of a new set of related peptides. Anti-VEGF antibodies are currently used in the clinic for regulating angiogenesis in cancer and age-related macular degeneration treatment. In this context, our aim is to develop smaller molecular entities with high affinity for the growth factor by a structure activity relationship approach. The cyclic disulfide peptide v114* was modified in several ways, including truncation, substitution, and variation of the size and nature of the cycle. The results indicated that truncation or substitution of the four N-terminal amino acids did not cause severe loss in affinity, allowing potential peptide labeling. Increase of the cycle size or substitution of the disulfide bridge with a thioether linkage drastically decreased the affinity, due to an enthalpy penalty. The leucine C-terminal residue positively contributed to affinity. Cysteine N-terminal acetylation induced favorable ΔΔG° and ΔΔH° of binding, which correlated with free peptide CD spectra changes. We also propose a biochemical model to extrapolate Ki from IC50 values measured in the displacement assay. These calculated Ki correlate well with the Kd values determined by extensive direct and reverse ITC measurements.

RESUMEN

Based on bioinformatics interrogation of the genome, >500 mammalian protein kinases can be clustered within seven different groups. Of these kinases, the mitogen-activated protein kinase (MAPK) family forms part of the CMGC group of serine/threonine kinases that includes extracellular signal regulated kinases (ERKs), cJun N-terminal kinases (JNKs), and p38 MAPKs. With the JNKs considered attractive targets in the treatment of pathologies including diabetes and stroke, efforts have been directed to the discovery of new JNK inhibitory molecules that can be further developed as new therapeutics. Capitalizing on our biochemical understanding of JNK, we performed in silico screens of commercially available chemical databases to identify JNK1-interacting compounds and tested their in vitro JNK inhibitory activity. With in vitro and cell culture studies, we showed that the compound, 4'-methyl-N(2)-3-pyridinyl-4,5'-bi-1,3-thiazole-2,2'-diamine (JNK Docking (JD) compound 123, but not the related compound (4'-methyl-N~2~-(6-methyl-2-pyridinyl)-4,5'-bi-1,3-thiazole-2,2'-diamine (JD124), inhibited JNK1 activity towards a range of substrates. Molecular docking, saturation transfer difference NMR experiments and enzyme kinetic analyses revealed both ATP- and substrate-competitive inhibition of JNK by JD123. In characterizing JD123 further, we noted its ATP-competitive inhibition of the related p38-γ MAPK, but not ERK1, ERK2, or p38-α, p38-ß or p38-δ. Further screening of a broad panel of kinases using 10µM JD123, identified inhibition of kinases including protein kinase Bß (PKBß/Aktß). Appropriately modified thiazole diamines, as typified by JD123, thus provide a new chemical scaffold for development of inhibitors for the JNK and p38-γ MAPKs as well as other kinases that are also potential therapeutic targets such as PKBß/Aktß.

RESUMEN

INTRODUCTION: Epidemiological and toxicological evidence suggests lower risk of smokeless tobacco (ST) products compared to cigarettes. Less is known, however, about consumer perceptions and use of novel forms of ST, including snus and dissolvable tobacco. METHODS: In this study, we conducted in-person experimental auctions in Buffalo, NY, Columbia, SC, and Selinsgrove, PA with 571 smokers to test the impact of information and product trials on smokers' preferences. Auctions were conducted between November 2010-November 2011. RESULTS: We found no evidence of an impact of product trials on demand in our auctions. Anti-ST information increased demand for cigarettes when presented alone, but when presented with pro-ST information it decreased demand for cigarettes. It did not decrease demand for ST products. Anti-smoking information increased demand for ST products, but did not affect cigarette demand. CONCLUSIONS: These findings suggest that credible and effective communications about tobacco harm reduction should reinforce the negative effects of smoking.

RESUMEN

The traditional Medicare fee-for-service program may be able to purchase clinical laboratory test services at a lower cost through competitive bidding. Demonstrations of competitive bidding for clinical laboratory tests have been twice mandated or authorized by Congress but never implemented. This article provides a summary and review of the final design of the laboratory competitive bidding demonstration mandated by the Medicare Modernization Act of 2003. The design was analogous to a sealed bid (first price), clearing price auction. Design elements presented include covered laboratory tests and beneficiaries, laboratory bidding and payment status under the demonstration, composite bids, determining bidding winners and the demonstration fee schedule, and quality under the demonstration. Expanded use of competitive bidding in Medicare, including specifically for clinical laboratory tests, has been recommended in some proposals for Medicare reform. The presented design may be a useful point of departure if Medicare clinical laboratory competitive bidding is revived in the future.

RESUMEN

Many reports and studies have noted that a significant portion of problem-oriented coastal science does not actually link to decisions. Here, three competitively funded project case studies are studied to determine what funders can and should do to better link science with decisions. The qualitative analysis used for this study indicates that the studied program was seen as being unusually attentive to the issue of linking science to decisions, as opposed to simply generating new knowledge. Nevertheless, much of the data indicate that funders can and should do more. Three ideas figured most prominently in the qualitative data: (1) funders should do more to ensure that the problem itself is defined more thoroughly with people who are envisioned as potential users of the science; (2) funders need to allocate more resources and attention to communicating effectively (with users) throughout the project; and (3) funders need to demand more engagement of users throughout the project. These findings have important implications for how funders review and support science, especially when competitive processes are used. Most importantly, funders should adjust what kind of science they ask for. Secondly, funders need to change who is involved in the review process. Currently, review processes focus on knowledge generation, which means that the reviewers themselves have expertise in that area. Instead, review panels should be balanced between those who focus on knowledge generation and those who focus on linking knowledge to decisions; this is a separate but critical discipline currently left out of the review process.

RESUMEN

The increasing intensity of treatment, the widespread adoption of factor VIII and IX prophylaxis and increasing usage over the past decade have led to haemophilia becoming an almost uniquely expensive condition to treat. The average adult with severe haemophilia A in the UK used 250,000 IU of factor VIII in 2011/2012, at a cost in excess of £ 100,000 p.a. The cost to the end-user may be considerably higher than this for some US patients supplied by home care companies with high on-costs. This has led to a high level of administrative scrutiny of treatment and an imperative to procure clotting factor concentrates more efficiently and collectively. National procurement schemes have run successfully in various countries and will become commoner. The UK system of procurement is described. This system, following EU procurement rules, evaluated products technically and by price. The price of bioequivalent products was determined by reverse e-auction. Considerable cost reductions were achieved whilst retaining all suppliers and maintaining a degree of prescribing freedom. Elements of this system could be more widely applied.

Non-coding (nc) RNAs are increasingly recognized to play important regulatory roles in eukaryotic gene expression. The highly abundant and essential 7SK ncRNA has been shown to negatively regulate RNA Polymerase II transcription by inactivating the positive transcription elongation factor b (P-TEFb) in cellular and Tat-dependent HIV transcription. Here, we identify a more general, P-TEFb-independent role of 7SK RNA in directly affecting the function of the architectural transcription factor and chromatin regulator HMGA1. An important regulatory role of 7SK RNA in HMGA1-dependent cell differentiation and proliferation regulation is uncovered with the identification of over 1500 7SK-responsive HMGA1 target genes. Elevated HMGA1 expression is observed in nearly every type of cancer making the use of a 7SK substructure in the inhibition of HMGA1 activity, as pioneered here, potentially useful in therapy. The 7SK-HMGA1 interaction not only adds an essential facet to the comprehension of transcriptional plasticity at the coupling of initiation and elongation, but also might provide a molecular link between HIV reprogramming of cellular gene expression-associated oncogenesis.
