Do Insurers With Greater Market Power Negotiate Consistently Lower Prices for Hospital Care? Evidence From Hospital Price Transparency Data. Med Care Res Rev 2024; 81:78-84. [PMID: 37594219 DOI: 10.1177/10775587231193475] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 08/19/2023]
Abstract
This study examined if greater insurer market power was associated with consistently lower negotiated prices within each hospital for 44 shoppable and emergency procedures, using price transparency data disclosed by 1,506 hospitals in metropolitan areas. We used multi-level fixed effects models to estimate the within-hospital variation in plan-level insurer-negotiated prices (from the largest insurer, the second largest insurer, other major insurers, and nonmajor insurers) and cash-pay prices as a function of insurer market power. For shoppable services, relative to nonmajor insurers, the largest, second largest, and other major insurers negotiated 23%, 16%, and 3% lower prices, respectively, while cash prices were 17% higher. For emergency room visits, while the largest insurers paid 5% less than nonmajor insurers, the second largest and other major insurers did not pay lower prices. Stratified analyses by type of shoppable services found varying magnitudes and patterns of price discounts associated with insurer market power.

Characteristics of Prescription Drug Fills Using Pharmacy-Pharmacy Benefit Manager Discount Programs: The "GoodRx" Model. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2024; 27:35-42. [PMID: 37879400 DOI: 10.1016/j.jval.2023.10.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 09/27/2023] [Accepted: 10/16/2023] [Indexed: 10/27/2023]
Abstract
OBJECTIVES This study aimed to characterize products using pharmacy-pharmacy benefit manager (PBM) discounts and to estimate the association among such discounts, prescription utilization, and out-of-pocket costs. METHODS This is a retrospective cohort study using IQVIA's Formulary Impact Analyzer, which contains anonymized, individual-level pharmacy claims representing US retail pharmacy transactions. We focused on 20 products with the greatest number of transactions using a pharmacy-PBM discount. Our unit of analysis was a treatment episode, defined as the length of time from an incident fill to no continuous use for 60 consecutive days after allowing for indefinite stockpiling. Outcome measures included products with greatest pharmacy-PBM discount use, characteristics of treatment episodes, and out-of-pocket costs with and without pharmacy-PBM discount. RESULTS Across all products, 3.82% of transactions and 7.69% of treatment episodes were accompanied by a pharmacy-PBM discount. Commonly discounted products included generic treatments for chronic disease (lisinopril, levothyroxine, metformin) and neuropsychiatric conditions (alprazolam, amphetamine, buprenorphine, hydrocodone). The median postdiscount out-of-pocket cost was >2.5-fold higher during treatment episodes with a discount than those without ($15.15, interquartile range [IQR] $8.53-32.00, vs $5.88, IQR $1.40-15.00). Median treatment episode duration was 249 days (IQR 132-418) with discount use compared with 236 days (IQR 121-396) without discount use, although treatment episodes that began with a discount had fewer transactions per treatment episode and were shorter (median 212 days, IQR 114-360) than those that did not (313 days, IQR 178-500). CONCLUSIONS Pharmacy-PBM discounts may foster market competition and improve access for under- and uninsured individuals; however, these programs may not generate savings for many insured individuals.

Filgrastim and infliximab biosimilar uptake in Medicare Advantage compared with Traditional Medicare, 2016-2019. J Manag Care Spec Pharm 2024; 30:15-21. [PMID: 38153867 PMCID: PMC10775772 DOI: 10.18553/jmcp.2024.30.1.15] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/30/2023]
Abstract
BACKGROUND Medicare Advantage (MA) and Traditional Medicare face different financing structures and incentives and may implement different strategies to encourage biosimilar uptake. Strategies used by health insurers can influence biosimilar uptake, which can in turn promote savings to insurers and patients. OBJECTIVE To compare filgrastim and infliximab biosimilar uptake between MA and Traditional Medicare from 2016 to 2019 and examine biosimilar uptake by different MA carriers and plan types (Health Maintenance Organization [HMO] or Preferred Provider Organization). METHODS We use a 2016-2019 nationally representative random 20% sample of the carrier (physician) and outpatient paid claims for Traditional Medicare data and final-action carrier and outpatient records for MA data. We compare quarterly biosimilar uptake from 2016 to 2019 for the first 2 drugs with biosimilar competition: (1) filgrastim, (Neupogen, originator), and biosimilars tbo-filgrastim (GRANIX) and filgrastim-sndz (ZARXIO), and (2) infliximab (Remicade, originator), and biosimilars infliximab-dyyb (Inflectra) and infliximab-abda (Renflexis). RESULTS From their introduction, there was consistently greater uptake of filgrastim and infliximab biosimilars in MA compared with Traditional Medicare. By Q4 2019, filgrastim biosimilar uptake was 7.6 percentage points higher in MA (80.3%) than Traditional Medicare (72.7%). By Q4 2019, infliximab biosimilar uptake was 28.7% and 15.4% in MA and Traditional Medicare, respectively. Kaiser HMO plans were primarily responsible for the higher uptake of biosimilars in MA; in Q4 2019, filgrastim and infliximab biosimilar uptake was 98.8% and 78.8%, respectively. CONCLUSIONS Our findings suggest that filgrastim and infliximab biosimilar uptake is greater in MA compared with Traditional Medicare, which is driven in part by particularly high uptake of biosimilars in MA Kaiser HMO plans. This highlights the need for future work to examine specific strategies and levers employed by MA Kaiser HMO plans and other insurers to increase biosimilar uptake, which can lead to cost savings for physician-administered drugs.

U.S. Hospitals' Administrative Expenses Increased Sharply During COVID-19. J Gen Intern Med 2023; 38:1887-1893. [PMID: 36952083 PMCID: PMC10035469 DOI: 10.1007/s11606-023-08158-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2022] [Accepted: 03/10/2023] [Indexed: 03/24/2023]
Abstract
BACKGROUND In response to the declining utilization and patient revenue due to the COVID-19 pandemic, the U.S. hospital industry furloughed at least 1.4 million health care workers to contain their clinical-related expenses. However, it remains unclear how hospitals responded by adjusting their administrative expenses, which account for more than a quarter of U.S. hospitals' spending, a proportion substantially higher than that of other industrialized countries. Examining changes in hospitals' administrative expenses during the COVID-19 pandemic is important for understanding hospitals' cost-containment behaviors under operational shocks during a pandemic. OBJECTIVE To assess changes in hospitals' administrative expenses and clinical expenses during the COVID-19 pandemic in 2020. DESIGN Time-series observational study. PARTICIPANTS 1420 Medicare-certified general acute-care hospitals with fiscal years starting in January and continuously operating during 2016-2020. MAIN MEASURES Hospitals' annual administrative expenses and clinical expenses. KEY RESULTS Hospitals' median administrative and clinical expenses both increased consistently around 4% each year from 2016 to 2019. From 2019 to 2020, the median administrative expenses grew by 6.2% while the median clinical expenses grew by 0.6%. The interrupted time-series regression estimated an additional 6.4% (95% CI, 4.5 to 8.2%) increase in administrative expenses in 2020, relative to the pre-COVID annual increase of 3.9% (95% CI, 3.3 to 4.4%), while an additional increase in clinical expenses in 2020 (0.5%; 95% CI, -0.3 to 1.4%) did not differ from the pre-COVID annual increase of 3.7% (95% CI, 3.5 to 4%). Stratified analysis showed hospitals with larger utilization volume, located in states with lower COVID-19 burden, or situated in counties with higher median household income experienced larger increase in administrative expenses in 2020. CONCLUSIONS In 2020, administrative expenses grew much faster than clinical expenses, resulting in a larger share of hospital financial resources allocated to administrative activities. Higher administrative expenses might reflect hospitals' operational effort in response to the pandemic or inefficient cost management.

Abstract
Importance Although manufacturer-sponsored coupons are commonly used, little is known about how patients use them within a treatment episode. Objectives To examine when and how frequently patients use manufacturer coupons during a treatment episode for a chronic condition, and to characterize factors associated with more frequent use. Design, Setting, and Participants This is a retrospective cohort study of a 5% nationally representative sample of anonymized longitudinal retail pharmacy claims data from October 1, 2017, to September 30, 2019, obtained from IQVIA's Formulary Impact Analyzer. The data were analyzed from September to December 2022. Patients with new treatment episodes using at least 1 manufacturer coupon over a 12-month period were identified. This study focused on patients with 3 or more fills for a given drug and characterized the association of the outcomes of interest with patient, drug, and drug class characteristics. Main Outcomes and Measures The primary outcomes were (1) the frequency of coupon use, measured as the proportion of prescription fills accompanied by manufacturer coupon within the treatment episode, and (2) the timing of first coupon use relative to the first prescription fill within the treatment episode. Results A total of 36 951 treatment episodes accounted for 238 474 drug claims and 35 352 unique patients (mean [SD] age, 48.1 [18.2] years; 17 676 women [50.0%]). Among these episodes, nearly all instances (35 103 episodes [95.0%]) of first coupon use occurred within the first 4 prescription fills. Approximately two-thirds of treatment episodes (24 351 episodes [65.9%]) used a coupon for the incident fill. Coupons were used for a median (IQR) of 3 (2-6) fills. The median (IQR) proportion of fills with a coupon was 70.0% (33.3%-100.0%), and many patients discontinued the drug after the last coupon. After adjustment for covariates, there was no significant association between an individual's out-of-pocket costs or neighborhood-level income and the frequency of coupon use. The estimated proportion of fills with a coupon was greater for products in competitive (19.5% increase; 95% CI, 2.1%-36.9%) or oligopolistic (14.5% increase; 95% CI, 3.5%-25.6%) markets than monopoly markets when there is only 1 drug in the therapeutic class. Conclusions and Relevance In this retrospective cohort analysis of individuals receiving pharmaceutical treatment for chronic diseases, the frequency of manufacturer-sponsored drug coupon use was associated with the degree of market competition, rather than patients' out-of-pocket costs.

Accelerated approval drug labels often lack information for clinical decision-making. Pharmacotherapy 2023; 43:300-304. [PMID: 36872463 DOI: 10.1002/phar.2789] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/20/2023] [Accepted: 02/22/2023] [Indexed: 03/07/2023]
Abstract
STUDY OBJECTIVE We evaluated US Food and Drug Administration labels for drugs approved under the accelerated approval pathway and whether these labels contained in sufficient information regarding their accelerated approval. DESIGN Retrospective, observational, cohort study. DATA SOURCE Label information for drugs with an accelerated approved indication were ascertained from two online platforms: Drugs@FDA and FDA Drug Label Repository. INTERVENTION Drugs with indications receiving accelerated approval after January 1, 1992, but had not received full approval by December 31, 2020. MEASUREMENTS Outcomes include whether the drug label indicated the use of the accelerated approval pathway, identified the specific surrogate marker(s) that supported it, or described the clinical outcomes being evaluated in post-approval commitment trials. RESULTS 253 clinical indications corresponding to 146 drugs received accelerated approval. We identified a total of 110 accelerated approval indications across 62 drugs that had not received full approval by December 31, 2020. A total of 13% of labels for accelerated approved indications lacked sufficient information that approval was via the accelerated approval or based on surrogate outcome measures: 7% did not mention accelerated approval but described surrogate markers, 4% did not mention accelerated approval nor describe surrogate markers, and 2% mentioned accelerated approval but did not describe surrogate markers. No label described the clinical outcomes being evaluated in post-approval commitment trials. CONCLUSION Labels for accelerated approved clinical indications that do not yet have full approval should be revised to include the information required in the FDA guidance to help guide clinical decision-making.

Abstract
OBJECTIVE To determine if greater non-profit hospital spending for community benefits is associated with better health outcomes in the county where they are located. DATA SOURCES AND STUDY SETTING Community benefit data from IRS Form 990/Schedule H was linked to health outcome data from Area Health Resource Files, Map the Meal Gap, and Medicare claims from the Center for Medicare and Medicaid Services at the county level. Counties with at least one non-profit hospital in the United States from 2015 to 2019 (N = 5469 across the 5 years) were included. STUDY DESIGN We ran multiple regressions on community benefit expenditures linked with the number of health professionals, food insecurity, and adherence to diabetes and hypertension medication for each county. DATA COLLECTION The three outcomes were chosen based on prior studies of community benefit and a recent survey sent to 12 health care executives across four regions of the U.S. Data on community benefit expenditures and health outcomes were aggregated at the county level. PRINCIPAL FINDINGS Average hospital community benefit spending in 2019 was $63.6 million per county ($255 per capita). Multivariable regression results did not demonstrate significant associations of total community benefit spending with food insecurity or medication adherence for diabetes. Statistically significant associations with the number of health professionals per 1000 (coefficient, 12.10; SE, 0.32; p < 0.001) and medication adherence for hypertension (marginal effect, 0.27; SE, 0.09; p = 0.003) were identified, but both would require very large increases in community benefit spending to meaningfully improve outcomes. CONCLUSIONS Despite varying levels of non-profit hospital community benefit investment across counties, higher community benefit expenditures are not associated with an improvement in the selected health outcomes at the county level. Hospitals can use this information to reassess community benefit strategies, while federal, state, and local governments can use these findings to redefine the measures of community benefit they use to monitor and grant tax exemption.

Abstract
OBJECTIVES To measure the association between patient activation and hospitalization or emergency department (ED) visits among adults with chronic diseases. STUDY DESIGN Systematic review and meta-analysis. METHODS A systematic review of English articles was performed using the following databases: PubMed, Cochrane Library, Web of Science, PsycINFO, and Embase. Articles were searched from 2005 until July 2021. Observational studies that measured the association between patient activation, measured by the Patient Activation Measure (PAM), and hospitalization or ED visits among adults with chronic or multichronic diseases were included. Pairs of reviewers independently screened the studies and extracted data for qualitative and quantitative synthesis. The methodological quality was assessed using the Quality in Prognostic Studies (QUIPS) tool. RESULTS A total of nine observational studies (153,121 participants) were included in the qualitative synthesis, whereas six were pooled in the quantitative synthesis (151,359 participants). High levels of patient activation were significantly associated with a reduced risk for both hospitalizations (RR [95% CI] = 0.69 [0.61; 0.77], I2 = 78%) and ED visits (RR [95% CI] = 0.76 [0.70; 0.84], I2 = 72%). CONCLUSIONS Our findings suggest the existence of an inverse association between patient activation and healthcare resources utilization. Further observational studies are needed to fully comprehend the magnitude of this association.

Association Between Open Payments-Reported Industry Transfers of Value and Prostaglandin Analog Prescribing in the US. JAMA Ophthalmol 2022; 140:855-862.

Abstract
Importance Reported transfers of value (TOV) from pharmaceutical companies have been associated with greater use of branded anti-vascular endothelial growth factor agents by ophthalmologists, but payment under the Medicare Part B buy-and-bill model includes a financial incentive to choose costlier agents, potentially confounding analyses of pharmaceutical TOV and prescribing patterns. How these reported TOV are associated with prescribing patterns for prescription eye drops, not subject to the incentives created by Part B payments, should be considered. Objective To assess the association between prostaglandin analog (PGA) eye drop prescribing and reported nonresearch TOV by makers of branded PGAs to US vision care professionals. Design, Setting, and Participants This retrospective cohort analysis used a 20% nationally representative sample of 2018 Medicare Part D claims and industry TOV reported to the Open Payments program. Optometrists and ophthalmologists who had more than 10 claims for PGA drops in the 20% sample were analyzed. Analysis took place from June 2021 to February 2022. Main Outcomes and Measures Multivariable logistic regression assessing the association between membership in strata of reported TOV and branded PGA prescribing rate, controlling for prescriber demographic factors, local area practices, total PGA prescribing volume, and plan formularies involved. Results A total of 20 612 ophthalmologists and 5426 optometrists (7449 [29%] female and 18 589 [71%] male) prescribed PGA eye drops. Of these, 9685 (37%) were reported to have received TOV from manufacturers of branded PGAs in 2018, totaling $5 060 346. The median (IQR) reported TOV was $65 ($24-$147). Multivariable logistic regression showed that the predicted probability of primarily prescribing branded PGAs among prescribers who reported receiving no TOV was 12.9% (95% CI, 12.4%-13.4%). This figure increased to 19.6% (95% CI, 18.8%-20.4%) among prescribers receiving TOV, a 50% increase. There was a dose-response association, such that the top 10% of TOV recipients had a 29.2% probability (95% CI, 26.4%-31.9%) of preferential branded use. Conclusions and Relevance While the median reported TOV to a PGA prescriber was relatively low in this study, there was a positive association between amount of reported nonresearch TOV received from PGA makers and the frequency of branded PGA use. This shows that small reported TOV were associated with differences in prescribing. High rates of branded PGA prescribing may pose a cost burden to patients that affects adherence. Clinicians and policy makers should be aware of these associations.

Trajectories of prices in generic drug markets: what can we infer from looking at trajectories rather than average prices? HEALTH ECONOMICS REVIEW 2022; 12:37. [PMID: 35819735 PMCID: PMC9278003 DOI: 10.1186/s13561-022-00384-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Accepted: 06/15/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Well-functioning competitive markets are key to controlling generic drug prices. This is important since over 90% of all drugs sold in the US are generics. Recently, there have been examples of large price increases in the generic market. METHODS This paper examines price trajectories for generic drugs using a group-based trajectory modelling approach (GBTM). We fit the model using quarterly price information in the IBM MarketScan claims database for the past decade. RESULTS We identify three dominant price trajectories for this period: rapid increase trajectories, slow decline and rapid decline. Most generic drugs show a slow or a rapid decline in price trajectories. However, around 17% of all generic drugs show rapid price increase trajectories. CONCLUSIONS As Congress is exploring an excise tax on drugs whose list price increases faster than the rate of inflation, we discuss what drugs would be most likely to be affected by this law.

Abstract
BACKGROUND The U.S. Food and Drug Administration provides accelerated approval to drugs on the basis of surrogate end points deemed to be "reasonably likely" to predict clinical benefit. To receive full approval, drugs must complete a confirmatory trial. Although most accelerated approved drugs ultimately receive full approval, others remain on the market without full approval for many years, and some are withdrawn before full approval is granted. Until confirmatory trials are completed and full approval is granted, there is uncertainty surrounding each drug's clinical benefits. OBJECTIVE To estimate fee-for-service Medicare payments on accelerated approved drugs without full approvals. DESIGN Cross-sectional analysis. SETTING Fee-for-service Medicare Part B and Part D drug claims in 2019. PARTICIPANTS Beneficiaries enrolled in Medicare Part B and Part D plans. MEASUREMENTS Medicare spending for drugs treating accelerated approved indications without full approval, beneficiary spending, and drug characteristics. RESULTS In 2019, 45 drugs associated with 69 accelerated approved indications lacked full approval. Of those, the fee-for-service Medicare program spent $1.2 billion on 36 drugs across 55 indications. Medicare beneficiaries had $209 million in out-of-pocket spending on these drugs. Oncology drugs represented 82% of these indications and 72% of the Medicare spending. Extrapolating to Medicare Advantage, total Medicare spending on these drugs in 2019 was $1.8 billion. LIMITATIONS The study drugs may have clinical benefit and may come to receive full approval after this analysis. The algorithm used to identify accelerated approved indications is novel. Generalizability to other years is unclear. CONCLUSION In 2019, fee-for-service Medicare spent $1.2 billion on accelerated approved drugs without full approval. Medicare should adjust incentives to encourage sponsors to complete confirmatory trials as soon as possible. PRIMARY FUNDING SOURCE Laura and John Arnold Foundation.

COVID-19 and Hospital Financial Viability in the US. JAMA HEALTH FORUM 2022; 3:e221018. [PMID: 35977260 PMCID: PMC9107033 DOI: 10.1001/jamahealthforum.2022.1018] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 03/24/2022] [Indexed: 11/18/2022] Open
Abstract
Question How did the financial viability of US hospitals change during the COVID-19 pandemic? Findings In this cross-sectional study of 2163 US hospitals, a sizeable reduction in the operating margins of US hospitals was found in 2020. However, their overall profit margins remained similar to those in prior years, and government, rural, and smaller hospitals generated higher overall profit margins during 2020 than in prior years. Meaning The study results suggest that the COVID-19 relief fund effectively offset the operational financial losses of hospitals during the COVID-19 era, particularly for government, rural, and smaller hospitals, which are typically more financially vulnerable and have been supported by some targeted fund allocation. Importance The COVID-19 pandemic has had a negative association with hospital operations. To help health care facilities and clinicians stay financially viable during the COVID-19 pandemic, Congress provided $175 billion in subsidies. It remains unclear how much financial losses hospitals incurred owing to operational disruptions during the COVID-19 pandemic and whether subsidies were sufficient to offset the financial losses. Objective To assess changes in the operational financial performance and overall financial viability of hospitals during the COVID-19 pandemic. Design, Setting, and Participants This cross-sectional study included 1378 US hospitals whose fiscal years began in January and 785 hospitals whose fiscal years began in July (all with continuous observations from 2016 through 2020). RAND Hospital Data, a compiled and processed version of Medicare Cost Reports, were used. The data were analyzed on March 12, 2022. Exposures The operational disruptions experienced and relief funds received by US hospitals during the COVID-19 pandemic. Main Outcomes and Measures A hospital’s annual operating margin, overall profit margin, and other nonoperating income as a share of total revenue from January 2016 to December 2020. Results Among the 1378 hospitals with fiscal years beginning in January, the mean operating margin declined from –1.0% (95% CI,–1.9% to –0.1%) in 2019 to –7.4% (95% CI, –8.5% to –6.3%) in 2020. The mean share of other nonoperating income grew from 4.4% (95% CI, 4% to 4.7%) in 2019 to 10.3% (95% CI, 9.9% to 10.8%) in 2020. The mean overall profit in 2020 (6.7%; 95% CI, 5.4% to 8.1%) remained as stable as prior years. Government, rural, and smaller hospitals showed higher mean overall profit margins in 2020 than in 2019 (7.2% vs 3.7%, 7.5% vs 1.9%, and 6.7% vs 3.5%, respectively). These results remained consistent when hospitals whose fiscal years began in July were examined. Conclusions and Relevance The results of this cross-sectional study suggest that although hospitals experienced a sizeable reduction in operating margins in 2020, their overall profit margins remained similar to those in prior years, suggesting that the COVID-19 relief fund effectively offset the financial losses for hospitals during the COVID-19 pandemic. Government, rural, and smaller hospitals, which were supported by some targeted fund allocations, generated higher overall profit margins during 2020 than in prior years.

Abstract
BACKGROUND: Genetic therapies are a promising treatment for children born with spinal muscular atrophy (SMA); however, their high price tags can evoke coverage restrictions. OBJECTIVE: To assess variation in coverage guidelines across fee-for-service state Medicaid programs for 2 novel genetic therapies, nusinersen and onasemnogene abeparvovec, that treat SMA. We also assessed the association of these coverage guidelines with use of the 2 genetic therapies. METHODS: We evaluated fee-for-service Medicaid coverage policies for nusinersen and onasemnogene abeparvovec from publicly available websites for the period February 2020-March 2020. We then documented areas of agreement and disagreement across 4 key coverage domains. We used 2018 and 2019 state Medicaid drug utilization data to calculate the use of nusinersen across Medicaid programs and assessed that use against the restrictiveness of the coverage guidelines. RESULTS: We identified 19 state Medicaid coverage guidelines for nusinersen. Most states agreed on diagnostics requirements; however, there were disagreements based on ventilator status. We identified 17 state Medicaid coverage guidelines for onasemnogene abeparvovec. There was more discordance in these coverage guidelines compared with nusinersen, notably in domains of SMN2 gene count and ventilator status. When comparing utilization of nusinersen with coverage restrictions, we found that the more restrictive states had considerably lower utilization of nusinersen. CONCLUSIONS: There was significant variation across fee-for-service Medicaid coverage policies for nusinersen and onasemnogene abeparvovec. Although states can impose individual coverage guidelines for each drug, we presented policy options that could reduce variation and potentially decrease the cost burden of these drugs. DISCLOSURES: This study was funded by Arnold Ventures. The authors have no conflicts of interest to disclose.

Hospital resource allocation decisions when market prices exceed Medicare prices. Health Serv Res 2021; 57:237-247. [PMID: 34806174 DOI: 10.1111/1475-6773.13914] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 10/27/2021] [Accepted: 11/13/2021] [Indexed: 11/28/2022] Open
Abstract
OBJECTIVE To examine nonprofit hospitals' financial and spending allocations when the private sector payment rate is higher than the Medicare's payment rate. DATA SOURCES Hospital financial data for 2014-2018 from Center for Medicare and Medicaid Services Hospital Cost Reports, hospital characteristics from the American Hospital Association (AHA) Annual Survey. STUDY DESIGN Hospital and year level fixed effects regressions modeling each hospital's (1) operating net income per discharge equivalent (DE); (2) administrative cost per DE; (3) patient care cost per DE; (4) registered nurse per bed; charity care cost per DE; and (5) provision of unprofitable services as a function of the private sector to Medicare payment ratio (PMR). DATA COLLECTION/EXTRACTION METHODS Hospital/year-level data from hospital cost reports merged with AHA data. Samples included general short-term hospitals with nonprofit ownership, excluding critical access hospitals. PRINCIPAL FINDINGS The final sample included a total of 8862 hospital-year observations, with a mean PMR of 1.62. Nonprofit hospitals having a 0.1 higher PMR were associated with $257 (95% CI: $181-$334) increase in operating net income per DE; $66 (95% CI: $32-$99) increase in administrative cost per DE; $170 (95% CI: $120-$220) increase in patient care cost per DE; and $18 (95% CI: $10-$25) increase in charity care cost per DE. We found hospitals hired 0.86 (95% CI: -0.08 to 1.81) more registered nurses per 100 beds, but no evidence on providing more beds for unprofitable services, such as obstetric care, burn care, alcohol/drug abuse treatment, or psychiatric care. CONCLUSIONS Higher private sector prices led primarily to greater surplus and administrative cost for nonprofit hospitals and smaller increases in spending on services that will directly benefit patients.

Abstract
OBJECTIVES Self-insured employers cover more people than Medicare, Medicaid, or direct purchasers of private insurance.This study examined the ability of self-insured employers to negotiate hospital prices and the relationship between hospital prices and employer market power in the United States. STUDY DESIGN Repeated cross-section analysis of commercial claims. METHODS We used the US Census Bureau County Business Patterns data to estimate employer market power at the metropolitan statistical area (MSA)-year level and used the Truven Health MarketScan commercial claims to estimate mean hospital prices and price ratios at the MSA-year level (2010-2016). We calculated descriptive statistics for employer market power, mean hospitalization prices, and a case mix-adjusted price ratio measure during the study period and analyzed the 10 most concentrated labor markets. We estimated MSA-year-level ordinary least squares regressions of hospitalization price and the price ratio measure on employer market power. RESULTS Large self-insured employers had concentrated market power in very few MSAs in 2016. The mean value of our employer market power measure was 62 for 2016, compared with the mean value of 5410 for hospital market power in the United States. Regression analyses find a slight relationship: A 1-point increase in employer market power was associated with a $6.61 decrease in the hospitalization price (mean = $20,813), but this result becomes statistically insignificant once the models control for hospital wages. CONCLUSIONS Employer market power is low in most MSAs. Self-insured employers may consider building purchase alliances with state and local government employee groups to enhance their market power and lower negotiated prices for hospital services.

Abstract
IMPORTANCE Despite ongoing debate regarding the high prices that patients pay for prescription drugs, to our knowledge, little is known regarding the use of coupons, vouchers, and other types of copayment "offsets" that reduce patients' out-of-pocket drug spending. Although offsets reduce patients' immediate cost burden, they may encourage the use of higher-cost products and diminish health insurers' ability to optimize pharmaceutical value. OBJECTIVE To examine the drugs most commonly covered by offsets, the percentage of out-of-pocket costs covered by offsets, and the characteristics of patients using offsets for retail pharmacy transactions in the United States in 2017 through 2019. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort analysis was conducted of a 5% nationally random sample of anonymized pharmacy claims from IQVIA's Formulary Impact Analyzer, which captures more than 60% of all US pharmacy transactions. This analysis focused on 631 249 individuals who used at least 1 offset between October 1, 2017, and September 30, 2019. MAIN OUTCOMES AND MEASURES Offset source, types of drugs covered by offsets, offset dollar value and percentage of out-of-pocket payment covered, and county characteristics of offset recipients. RESULTS The 631 249 individuals in the study (361 855 female participants [57.3%]; mean [SD] age, 45.7 [18.6] years) had approximately 33 million prescription fills, of which 12.8% had an offset used. Of these, 50.2% originated from a pharmaceutical manufacturer, 47.2% originated from a pharmacy or pharmacy benefit manager (PBM), and 2.6% originated from a state assistance program. A total of 80.0% of manufacturer-sponsored offsets were concentrated among 6.2% of unique products, and 79.9% of pharmacy-PBM offsets were concentrated among 4.9% of unique products. Most manufacturer offsets (88.2%) were for branded products, while most pharmacy-PBM offsets were for generic products (90.5%). The median manufacturer offset was $51.00, covering 87.1% of out-of-pocket costs; the median pharmacy-PBM offset was $16.30, covering 39.3% of out-of-pocket costs. There was no meaningful association between offset magnitude and county-level income, health insurance coverage, or race/ethnicity. CONCLUSIONS AND RELEVANCE In this analysis of patient-level pharmacy claims from 2017 to 2019, approximately half of all offsets involved pharmacy-PBM contractual arrangements, and half were offered by manufacturers. All offsets were associated with a significant reduction in patients' out-of-pocket costs, were highly concentrated among a few drugs, and were generally not more generous among individuals in counties with lower income or larger Black or uninsured populations.

Abstract
OBJECTIVES Stand-alone prescription drug plans (S-PDPs) and Medicare Advantage prescription drug (MA-PD) plans are incentivized to cover outpatient medications differently. This could affect the coverage of inhalers that prevent costly exacerbations of chronic obstructive pulmonary disease (COPD), with impacts for the Medicare program and its beneficiaries. This study compared the coverage of guideline-recommended COPD inhalers between S-PDPs and MA-PD plans. STUDY DESIGN A cross-sectional analysis of the formularies for all 689 S-PDPs and 2578 MA-PD plans offered in 2017. METHODS We assessed each prescription drug plan's coverage of inhalers in 6 therapeutic categories recommended by the 2017 Global Initiative for Chronic Obstructive Lung Disease (GOLD) report and compared the use of prior authorization, step therapy, and coinsurance between S-PDPs and MA-PD plans. RESULTS In 2017, all S-PDPs and MA-PD plans covered at least 1 inhaler from each GOLD therapeutic category, except for long-acting β agonist/long-acting muscarinic antagonist combination inhalers. S-PDPs were more likely to require coinsurance for inhalers across all therapeutic categories, whereas MA-PD plans required prior authorization more frequently for 3 of the 6 therapeutic categories. S-PDPs required coinsurance more frequently than MA-PD plans for inhalers that treat mild (20.8% vs 11.4%; P < .001), moderate (40.0 vs 13.2%; P < .001), and severe (45.4% vs 11.0%; P < .001) disease. CONCLUSIONS Medicare Part D S-PDPs are more likely than MA-PD plans to require coinsurance for outpatient COPD inhalers, especially for severe disease. This likely reflects their different financial incentives and is an important consideration for providers and policy makers aiming to improve outpatient COPD management.

Comparing the value of community benefit and Tax-Exemption in non-profit hospitals. Health Serv Res 2021; 57:270-284. [PMID: 33966271 PMCID: PMC8928013 DOI: 10.1111/1475-6773.13668] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 03/30/2021] [Accepted: 04/14/2021] [Indexed: 11/28/2022] Open
Abstract
Objective We examined the characteristics of non‐profit hospitals providing more community benefits and charity care than value of their tax exemptions and how this relationship changed between 2011 and 2018. Data sources Primary dataset was schedule H Form IRS 990 data. This data was merged with the American Hospital Association, Medicare Hospital Cost Report, and the America Community Survey. Study design We measured six categories of tax benefits and 17 types of community benefits. Subtracting the average value of community benefits provided by for‐profit hospitals, we computed incremental community benefit and charity care provided by each non‐profit hospital. Extraction methods A nationally representative sample was created of 11 776 non‐profit hospital‐year observations from 1472 unique hospitals over the 2011 to 2018 period was created. Descriptive analyses and random effect logistic regression were used to show associations between hospital characteristics and difference between incremental net community benefits and the value of tax‐exemption. Principal findings After adjusting for community benefits provided by for‐profits hospitals, on average, non‐profit hospitals spent 5.9% (CI: 5.8%‐6.0%) of their total expenses on community benefits; 1.3% (CI: 1.2%‐1.3%) on charity care; and received 4.3% (CI: 4.2%‐4.4%) of total expenses in tax exemptions. A total of 38.5% of non‐profit hospitals did not provide more community benefit and 86% did not provide more charity care than the value of their tax exemption. Hospitals with fewer beds, providing residency education and located in high poverty communities were more likely to provide more incremental community benefits and charity care than the value of their tax exemption, while system affiliation had a negative association. Conclusion The amount of community benefits and charity care provided by non‐profits varied substantially across non‐profit hospitals. Establishing minimum requirements for non‐profit hospitals or publicly ranking hospitals based on their community benefit or charity care contributions, could encourage greater community benefits and charity care.

Charity Care and Community Benefit in Non-Profit Hospitals: Definition and Requirements. INQUIRY : A JOURNAL OF MEDICAL CARE ORGANIZATION, PROVISION AND FINANCING 2021; 58:469580211028180. [PMID: 34167375 PMCID: PMC8246580 DOI: 10.1177/00469580211028180] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Revised: 05/17/2021] [Accepted: 06/07/2021] [Indexed: 11/16/2022]
Abstract
Policymakers are using different ways to measure the community benefit provided by non-profit hospitals because different policy makers have different policy objectives. We compare 3 commonly used measures of community benefit; examine the correlation across the 3 measures; examine how the distribution of community benefits varies across non-profit hospitals; and compare the factors associated with the level of community benefit for each definition. The main dataset for this study is the Schedule H of IRS Form 990 data for 2017. We merged this data with the 2017 American Hospital Association (AHA), the 2017 CMS Hospital Cost Report, and the 2018 American Community Survey data. The final sample consists of 1904 non-profit hospitals. We define 3 measures of community benefit: (1) Total community benefits: combining all 17 possible measures in the 990 data; (2) Total community benefits less unreimbursed Medicaid care because it reflects a policy choice made by the state; and (3) only charity care. We also subdivided the community benefits into individual and service-based benefit. Gini Coefficients and descriptive analysis show the distribution of 3 types of community benefit measures. On average, hospitals spent 8.1% of their expenses on all community benefits; 4.3% on community benefits less unreimbursed Medicaid; and 1.7% on charity care. The provision of charity care showed more variation (Gini coefficient) than the other 2 measures. Different hospital and geographic characteristics were associated with each definition, suggesting that different types of hospitals place emphasis on different community benefits. When policy makers choose among different definitions of community benefit, they should consider what incentives they want to instill.

Abstract
It is widely accepted that the pathophysiology and treatment of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) could be considerably improved. The heterogeneity of ME/CFS and the confusion over its classification have undoubtedly contributed to this, although this would seem a consequence of the complexity of the array of ME/CFS presentations and high levels of diverse comorbidities. This article reviews the biological underpinnings of ME/CFS presentations, including the interacting roles of the gut microbiome/permeability, endogenous opioidergic system, immune cell mitochondria, autonomic nervous system, microRNA-155, viral infection/re-awakening and leptin as well as melatonin and the circadian rhythm. This details not only relevant pathophysiological processes and treatment options, but also highlights future research directions. Due to the complexity of interacting systems in ME/CFS pathophysiology, clarification as to its biological underpinnings is likely to considerably contribute to the understanding and treatment of other complex and poorly managed conditions, including fibromyalgia, depression, migraine, and dementia. The gut and immune cell mitochondria are proposed to be two important hubs that interact with the circadian rhythm in driving ME/CFS pathophysiology.

Abstract
OBJECTIVES Medicare Part B payment methods incentivize the use of more expensive injectable and infused drugs. We examined prescribing patterns in the context of intravenous (IV) iron, for which multiple similarly safe and efficacious formulations exist, with wide variations in price. STUDY DESIGN We conducted a retrospective cohort analysis of IV iron utilization and payment in the Medicare population between 2015 and 2017. METHODS This analysis used a national, random 20% sample of Medicare fee-for-service beneficiaries with Part B claims for IV iron between January 2015 and December 2017-a period before, during, and after a national shortage of iron dextran. This sample included 66,710 Medicare fee-for-service beneficiaries with at least 1 Part B claim for IV iron. RESULTS The greatest increase in utilization occurred in the most expensive iron formulation, ferric carboxymaltose; its market share rose from 27.4% of use in 2015 to 47.7% in 2017. The use of a less expensive formulation, iron dextran, decreased from 26.7% to 18.7% over the same period. An alternative payment model in Maryland hospitals was associated with markedly less utilization of ferric carboxymaltose, accounting for 4.7% of IV iron utilization in Maryland hospitals. CONCLUSIONS There was an increase in the dispensing of a higher-priced IV iron formulation associated with a shortage of a less expensive drug that persisted once the shortage ended. These findings in IV iron have broader implications for Part B drug payment policy because the price of the drug determines the physician and health system payment.

Abstract
OBJECTIVES Little is routinely disclosed about the costs of the pivotal clinical trials that provide the key scientific evidence of the treatment benefits of new therapeutic agents. We expand our earlier research to examine why the estimated costs may vary 100-fold. DESIGN A cross-sectional study of the estimated costs of the pivotal clinical trials supporting the approval of 101 new therapeutic agents approved by the US Food and Drug Administration from 2015 to 2017. METHODS We licensed a software tool used by the pharmaceutical industry to estimate the likely costs of clinical trials to be conducted by contract research organisations. For each trial we collected 52 study characteristics. Linear regression was used to assess the most important factors affecting costs. PRIMARY AND SECONDARY OUTCOME MEASURES The mean and 95% CI of 225 pivotal clinical trials using varying assumptions. We also assessed median estimated costs per patient, per clinic visit and per drug. RESULTS Measured as pivotal trials cost per approved drug, the 101 new molecular entities had an estimated median cost of US$48 million (IQR US$20 million-US$102 million). The 225 individual clinical trials had a median estimate of US$19 million (IQR US$12 million-US$33 million) per trial and US$41 413 (IQR, US$29 894-US$75 047) per patient. The largest single factor driving cost was the number of patients required to establish the treatment effects and varied from 4 patients to 8442. Next was the number of trial clinic visits, which ranged from 2 to 166. Our statistical model showed trial costs rose exponentially with these two variables (R2=0.696, F=257.9, p<0.01). CONCLUSIONS The estimated costs are modest for measuring the benefits of new therapeutic agents but rise exponentially as more patients and clinic visits are required to establish a drug effect.

Mutations in LAMB2 Are Associated With Albuminuria and Optic Nerve Hypoplasia With Hypopituitarism. J Clin Endocrinol Metab 2020; 105:5643661.

Abstract
CONTEXT Mutations in LAMB2, encoding the basement membrane protein, laminin β2, are associated with an autosomal recessive disorder characterized by congenital nephrotic syndrome, ocular abnormalities, and neurodevelopmental delay (Pierson syndrome). CASE DESCRIPTION This report describes a 12-year-old boy with short stature, visual impairment, and developmental delay who presented with macroscopic hematuria and albuminuria. He had isolated growth hormone deficiency, optic nerve hypoplasia, and a small anterior pituitary with corpus callosum dysgenesis on his cranial magnetic resonance imaging, thereby supporting a diagnosis of optic nerve hypoplasia syndrome. Renal histopathology revealed focal segmental glomerulosclerosis. Using next-generation sequencing on a targeted gene panel for steroid-resistant nephrotic syndrome, compound heterozygous missense mutations were identified in LAMB2 (c.737G>A p.Arg246Gln, c.3982G>C p.Gly1328Arg). Immunohistochemical analysis revealed reduced glomerular laminin β2 expression compared to control kidney and a thin basement membrane on electron microscopy. Laminin β2 is expressed during pituitary development and Lamb2-/- mice exhibit stunted growth, abnormal neural retinae, and here we show, abnormal parenchyma of the anterior pituitary gland. CONCLUSION We propose that patients with genetically undefined optic nerve hypoplasia syndrome should be screened for albuminuria and, if present, screened for mutations in LAMB2.

Abstract
Abstract
Introduction
Guidelines on falls prevention recommend case ascertainment based on opportunistic case ascertainment and referral in those who have fallen. In October 2009 we implemented a novel multidisciplinary, multifactorial falls, syncope and dizziness service with enhanced case-ascertainment through proactive, primary care-based screening for associated risk factors. In addition to comprehensive geriatric assessment, 25% of 4032 service participants underwent strength and balance training. The baseline outcomes have been previously reported.1 Funding was withdrawn, and the service closed on 31/01/2014. We examined the effect of service-closure on fractures presenting to secondary care with and without the service running.
Methods
An interrupted time series method was used. ICD-10 coded fracture numbers attending secondary care were determined (Hospital Episode Statistics from 01/02/2012-31/05/2017) for all North Tyneside residents ≥60 years at the time of service closure, including 25-months with, and 40-months without, service provision.
Results
There was a 0.9% (p=0.018) monthly reduction in falls over 25-months of service provision which increased during the winter months of a 9.8% (p=0.015) increase. In the month following the service closure there was an initial increase in fractures of 8.5% (p=0.231), followed by an increase in the monthly time trend of 1% (p=0.018). This resulted in a post-service monthly increase in fractures of 0.1%, an estimated extra 625 fractures over the 40-month post-service cessation period. At an average £8600 per fracture, the estimated cost may have been £5,375,000.
Conclusions
In this naturalistic experiment, following an initial drop in fractures, disinvestment in this service resulted in a rise in elders’ fractures presenting to secondary care. The closure of the service may have had a large unintended cost, averaging £1.5 million annually, versus annual running costs of £220,000. Further research is needed to control for patient-level characteristics and to establish the cost-effectiveness of the service.

Abstract
Abstract
Background
In 2009 we implemented a novel multidisciplinary, multifactorial falls, syncope and dizziness service model utilising proactive, primary care-based screening (≥60 years). Participants underwent comprehensive geriatric assessment, while 25% of the 4032 service participants had exercise training. All had additional lifestyle advice on exercise, alcohol intake, weight loss and smoking cessation. The preliminary outcomes of this approach have been previously reported, with occult atrial fibrillation, murmurs, ECG-evident ischaemic heart disease (IHD) etc reported to GPs for further action.1 Funding was withdrawn and the service closed on 31/01/2014. We examined IHD secondary care attendances with and without service provision.
Methods
Patients: North Tyneside residents ≥60 years at time of closure of the service in January 2014, who were presented acutely to secondary care with IHD using an interrupted time series method. ICD-10 coded IHD numbers were determined (Hospital Episode Statistics from 01/02/2012[date of a change in coding compared to service commencement in 2009] until 31/05/2017) including 25-months with, and 40-months without, service provision.
Results
The Table summarises the change in IHD +/- service provision; there was a significant reduction in IHD non-elective admissions during both time series’, but the reduction was significantly lower without service provision.
In addition, immediately following the service closure there was an initial increase in IHD complications of 18.4% (p=0.059) followed by an increase in the time trend of 2.7% (p=0.029), resulting in a 0.6% post-service monthly reduction in IHD complications.
Conclusions
Disinvestment in this service resulted in a slowdown in the underlying reduction of IHD diagnoses in secondary care. However, further research is needed to control for patient-level characteristics, the economic impact and to look at the effect of the service on other cardiovascular diseases.

Abstract
Abstract
Eleven laboratories collaboratively studied a liquid chromatographic (LC) method for determination of D-malic acid in apple juice. The mobile phase consisted of 16 mM L-valine and 8 mM copper acetate adjusted to pH 5.5 with NaOH. The UV detector was set at 330 nm, and a single reversed-phase LC column was used. Seven paired samples containing various amounts of D-malic acid ranging from 0 to 188 mg/100 mL of 12 Brix pasteurized apple juice were tested by each collaborator. Repeatability and reproducibility coefficients of variation ranged from 1.0 to 3.5% and 7.7 to 11.7%, respectively, within the range of 26 to 188 mg D-malic acid/100 mL of 12 Brix apple juice. The collabora tive study results demonstrated that the method could quantitate the economic adulteration of ap ple juice with DL-malic acid at lower levels than those reported with previous methods. The LC method for determination of D-malic acid in apple juice has been adopted first action by AOAC INTERNATIONAL.

Abstract
Abstract
A multilaboratory study was conducted to determine the limit of detection (LOD) of Staphylococcal enterotoxins (SET) in 5 foods. Cooked chicken, ham, potato salad, pasteurized liquid whole milk, and canned mushrooms were each spiked with a different enterotoxin (A, B, C1, D, or E), and tested at 0.25 and 0.5 ng/g SET levels to determine the LOD of the assay for those foods in a collaborative study. Unspiked controls were also included. A total of 19 laboratories representing government and industry participated. In this study, 1674 test portions were analyzed, of which 1638 were used in the statistical analysis. Of the 1638 test portions used in the statistical analysis, 1104 were spiked test portions, of which 1073 were positive by the VIDAS Staph enterotoxin II (SET 2) method. The detection rates at the 0.25 ng/mL level were cooked chicken, 98.2; ham, 99.0; potato salad, 99.1; liquid whole milk, 85.2; and canned mushrooms, 100. The detection rates at the 0.5 ng/mL level were cooked chicken, 97.4; ham, 98.1; potato salad, 100; liquid whole milk, 99.0; and canned mushrooms, 100. The data indicate that the SET 2 method is capable of detecting SET at 0.25 ng/g in cooked chicken, ham, potato salad, and canned mushrooms and at 0.5 ng/g in pasteurized liquid whole milk.

Abstract
AOAC Official Method 996.09, Visual Immunoprecipitate Assay (VIP®) for Escherichia coli O157:H7, was modified to incorporate a new enrichment protocol using BioControl EHEC8™ medium for testing raw and cooked beef. Foods were tested by VIP assay and the U.S. Department of Agriculture/Food Safety and Inspection Service (USDA/FSIS) enrichment procedure and the FDA Bacteriological Analytical Manual (BAM) isolation and confirmation techniques. A total of 15 collaborators participated. Raw and cooked ground beef were inoculated with E. coli O157:H7 at 2 different levels: a high level, where predominantly positive results were expect d, and a low level where fractional recovery was anticipated. Collaborators tested 396 test portions and controls by both methods, for a total of 792 test portions. Of the 396 paired test portions, 75 were positive and 230 were negative by both the VIP and culture methods. Eleven test portions were presumptively positive by VIP and could not be confirmed culturally; 32 were negative by VIP, but confirmed positive by culture; and 65 were negative by the culture method, but confirmed positive by the VIP method. There was no statistical difference between results obtained with the VIP for EHEC 8 h method and the culture method except for cooked beef, where the VIP had significantly higher recovery for one inoculation level.

Abstract
A multilaboratory study was conducted to compare the automated BAX® System to the standard cultural methods for detection of Salmonella in selected foods. Five food types—frankfurters, raw ground beef, mozzarella cheese, raw frozen tilapia fish, and orange juice—at 3 inoculation levels, were analyzed by each method. A sixth food type, raw ground chicken, was tested using 3 naturally contaminated lots. A total of 16 laboratories representing government and industry participated. In this study, 1386 samples were analyzed, of which 1188 were paired samples and 198 were unpaired samples. Of the 1188 paired samples, 461 were positive by both methods and 404 were negative by both methods. Thirty-seven samples were positive by the BAX System but negative by the standard reference method, and 11 samples were positive by standard cultural method and negative by the BAX System. Of the 198 unpaired samples, 106 were positive by the BAX System and 60 were positive by the standard cultural method. A Chi square analysis of each of the 6 food types, at the 3 inoculation levels tested, was performed. For all foods, the BAX System demonstrated results comparable to those of the standard reference methods based on the Chi square results.

Abstract
Abstract
A collaborative study was conducted to validate new enrichment methods for the TECRA Listeria Visual Immunoassay (TLVIA). These new methods incorporate a newly formulated medium, TECRA Listeria Enrichment Broth, which does not contain the highly toxic antifungal agent, cycloheximide. The new procedures will provide an alternative to the enrichment procedures described in AOAC Method 995.22. Three food types (raw ground beef, lettuce, and ice cream) were analyzed in the United States, and 2 food types (cooked turkey and cooked fish fillets) were analyzed in Australasia. Thirty collaborators participated in the study, 16 in Australasia and 14 in the United States. With the exception of one batch of ground beef, comparison of the proportion of positive test portions (p ≥ 0.05) showed no significant difference between the TLVIA and the reference method for the 5 foods at 3 inoculation levels. For the one batch of naturally contaminated raw ground beef, the TLVIA gave significantly more confirmed positive results than the reference method.

Abstract
Five different food types were analyzed by the Reveal for E. coli O157:H7 8-Hour Test System (Reveal 8) and either the U.S. Food and Drug Administration's Bacteriological Analytical Manual (BAM) culture method or the U.S. Department of Agriculture Food Safety Inspection Service (FSIS) culture method for the presence of E. coli O157:H7. A total of 27 laboratories representing academia and private industry in the United States and Canada participated. Food types were inoculated with E. coli O157:H7 at 2 different levels: a high level where predominantly positive results were expected, and a low level where fractional recovery was anticipated. During this study, 1110 samples and controls were analyzed by both the Reveal 8 and by BAM or FSIS by each of the collaborators (2220 samples in total). For each set of samples, 740 were artificially inoculated with E. coli O157:H7, and 370 were uninoculated controls. The Reveal 8 detected 528 presumptive positives of which 487 were confirmed positive by the BAM culture method. In comparison, BAM and FSIS detected 489 of the 740 artificially contaminated samples as positive. In an additional in-house study performed only on chilled and frozen raw ground beef, 240 artificially inoculated samples were analyzed by both the Reveal 8 and by FSIS. The Reveal 8 detected and confirmed 104 samples as positive compared to 79 confirmed positive by FSIS.

Abstract
OBJECTIVES New federal policies aim to focus Medicare Advantage (MA) plans on the needs of individuals with complex health conditions. Our objective was to examine enrollment patterns of MA beneficiaries with complex needs and the association of enrollment patterns with MA plan performance. DESIGN Cross-sectional study. SETTING The 2015 Medicare Health Outcome Survey baseline survey. PARTICIPANTS A total of 273 336 MA beneficiaries enrolled in 467 MA plans who lived in the community. MEASUREMENTS Complex patients included individuals 65 years and older with multiple self-reported chronic conditions and functional limitations and all patients with disabilities younger than 65 years. Outcomes included 27 performance measures reported under the 5-Star Part C Star Rating. Linear probability regression was used to examine the association of concentration of complex patients and performance measures. RESULTS Most complex patients were enrolled in general MA plans. Concentration of complex patients ranged from 25.9% in MA contracts in the lowest quintile to 68.9% in the top quintile. MA contract performance scores generally decreased as the concentration of complex patients increased. After adjusting for contract and enrollee characteristics, MA contracts with more complex patients performed less well on half of the Part C performance measures including patient experience, preventive care, and chronic care measures. CONCLUSION MA contracts with a high concentration of complex patients have lower performance scores on more than half of Part C measures. Further study is needed to understand whether these performance measures are capturing the delivery of poor care, deficiencies in the health plan's care systems, or whether some measures may not be appropriate for complex patients.

Abstract
Abstract
Background
Few studies report educational interventions for pediatric patients with asthma or diabetes type 1 as a fundamental instrument to engage them and improve their health. The aim of this systematic review and meta-analysis was to synthesize evidence about behavioral changes in life style, disease management and clinical outcome in pediatric patients after a structured educational intervention delivered by nurses.
Methods
A systematic review of the literature was carried out in MEDLINE, Scopus and CINHAL including only RCTs. Methodological quality of the studies was assessed using Cochrane tool. Meta-analyses on HbA1c reduction for diabetes and hospitalization, emergency department (ED) visits and medication for asthma were carried-out.
Results
Of the 3559 papers initially retrieved, 5 regarding diabetes and 19 asthma met the inclusion criteria for the systematic review and 14 for the meta-analyses. Included studies were highly heterogeneous in terms of type of intervention and follow-up duration. Almost all the studies showed an improvement but only few were statistically significant. All studies regarding diabetes showed a low risk of bias (only one RCTs had a high risk of bias in one domain), while almost all RCTs on asthma showed a high risk of bias. The pooled mean differences in favor of the experimental groups were: HBA1c -0.02 (IC95%: -0.26 - 0.22), Hospitalization 0.58 (IC95%: 0.19 - 1.78), Medication -0.10 (IC95%: -0.43 - 0.23), ED Visits 0.82 (IC95%: 0.44 - 1.54).
Conclusions
There is a general agreement about the central role of educational intervention delivered by nurses to pediatric patients and the assessment of the behavioral changes after educational interventions is strongly recommended in pediatric population. However, more efforts are requested in designing studies on patients with asthma and to program more appropriate follow-up and periodic recall in order to engage pediatric patients in the management of their own chronic disease.
Key messages

Comparing the Value of Nonprofit Hospitals' Tax Exemption to Their Community Benefits. INQUIRY: The Journal of Health Care Organization, Provision, and Financing 2019; 55:46958017751970.

Abstract
The tax-exempt status of nonprofit hospitals has received increased attention from policymakers interested in examining the value they provide instead of paying taxes. We use 2012 data from the Internal Revenue Service (IRS) Form 990, Centers for Medicare and Medicaid Services (CMS) Hospital Cost Reports, and American Hospital Association’s (AHA) Annual Survey to compare the value of community benefits with the tax exemption. We contrast nonprofit’s total community benefits to what for-profits provide and distinguish between charity and other community benefits. We find that the value of the tax exemption averages 5.9% of total expenses, while total community benefits average 7.6% of expenses, incremental nonprofit community benefits beyond those provided by for-profits average 5.7% of expenses, and incremental charity alone average 1.7% of expenses. The incremental community benefit exceeds the tax exemption for only 62% of nonprofits. Policymakers should be aware that the tax exemption is a rather blunt instrument, with many nonprofits benefiting greatly from it while providing relatively few community benefits.

Abstract
Abstract
Background: Triple negative breast cancer (TNBC) remains a heterogeneous clinical phenotype with few, known therapeutic targets. PARP inhibitors (PARPi) are the first approved, targeted therapy in TNBC, limited to germline BRCA mutant (BRCAm) cancers that lack homologous recombination repair capacity. Even in this context, resistance quickly emerges via secondary mutations that restore DNA repair ability. While DNA damage repair is an intriguing target in BRCA wild type (BRCAwt) TNBC due to inherent, genomic instability, PARPi alone have been ineffective in unselected populations. Systematic approaches to define novel drugs that sensitize BRCAwt and BRCAm TNBC to PARPi would greatly improve therapeutic efficacy and durability.
Methods: BRCAwt (HCC1806) and BRCAm (SUM149PT) cell lines were screened in duplicate using a 2,100-compound small molecule library. Cell lines were plated in media containing DMSO or sub-lethal doses of the PARPi, olaparib, onto Selleck Bioactive drug plates. Cell viability was assessed after 72 hours, then normalized to vehicle control. Hit cut-offs were predefined as log2 drug/DMSO of ≤ -0.7 with a viability difference greater than 20% -where stringent scoring thresholds were chosen to exceed the full range of scores observed in 816 empty control wells. Hits were sorted by target and pathway to provide mechanistic insight into the synergy of combinations. Drug combinations with the highest potential for near term translation were validated using GI50 viability assays in 9 BRCAwt and BRCAm TNBC cell lines. The most promising combination was further validated via immunoblotting, colony formation, and apoptosis assays.
Results: Several drug classes affecting well-known oncogenic signaling pathways conferred sensitivity to PARPi, with more hits in the BRCAm cell line. Relevant druggable targets sensitizing cells to olaparib in BRCAm TNBC that met the predefined cut-point were inhibitors of PI3K (pan-PI3K, PI3Kα and PI3Kβ specific), VEGFR, MEK, EGFR, NF-kB, aurora kinase and several DNA damaging agents. Aurora kinase, EGFR, and NF-kB inhibition sensitized cells to olaparib, yet upon further validation, synergy was mild. The screen identified ATM inhibitors, KU-55933 and KU-60019, as sensitizers of BRCAm cells to olaparib. The potent ATM inhibitor, AZD0156, and olaparib were a highly synergistic combination validated in all 9 BRCAm and BRCAwt TNBC cell lines via cell viability, annexin V, and colony formation assays. Immunoblotting of relevant DNA damage repair proteins showed that olaparib caused upregulation of p-ATM in BRCAm and BRCAwt cells. p-ATM expression decreased in response to combination ATM and PARP inhibition. Attenuated levels of p-ATM resulted in increased levels of p- and T-γH2AX, indicating an accumulation of double stranded DNA breaks.
Conclusion: In vitro, inhibition of several relevant, oncogenic pathways yielded sensitivity to PARPi in TNBC. We identified the ATM inhibitor, AZD0156, and olaparib as a potent combination regardless of BRCA status, a finding currently being evaluated in patient-derived in vivo models. Combination ATM plus PARP inhibitor therapy is a promising and feasible approach for near term translation in metastatic TNBC.

Abstract
IMPORTANCE A critical question in health care is the extent of scientific evidence that should be required to establish that a new therapeutic agent has benefits that outweigh its risks. Estimating the costs of this evidence of efficacy provides an important perspective. OBJECTIVE To estimate costs and assess scientific characteristics of pivotal efficacy trials that supported the approval of new therapeutic agents by the US Food and Drug Administration (FDA) from 2015 to 2016. DESIGN AND SETTING This study identified 59 novel therapeutic drugs using the annual summary reports from the FDA Center for Drug Evaluation and Research. ClinicalTrials.gov, FDA reviews, and peer-reviewed publications that were publicly available in 2017 were used to identify 52 characteristics of each efficacy trial. Costs were calculated with a global clinical trial cost assessment tool available to contract research organizations and pharmaceutical sponsors. MAIN OUTCOMES AND MEASURES Estimated mean cost and 95% CIs based on industry benchmark data from 60 countries. Measures of trials' scientific characteristics included trial design (no control group, placebo, and active drug), end point (surrogate outcome, clinical scale, and clinical outcome), patient enrollment, and treatment duration. RESULTS A total of 138 pivotal clinical trials provided the basis for approval of 59 new therapeutic agents by the FDA from 2015 to 2016, with a median estimated cost of $19.0 million (interquartile range, $12.2 million-$33.1 million). Estimated costs ranged from less than $5 million for trials without a control group for 3 orphan drugs with fewer than 15 patients each to $346.8 million (95% CI, $252.0 million-$441.5 million) for a noninferiority trial with end points assessing clinical benefit. Twenty-six of 138 trials (18.8%) were uncontrolled, with a mean estimated cost of $13.5 million (95% CI, $10.1 million-$16.9 million). Trials designed with placebo or active drug comparators had an estimated mean cost of $35.1 million (95% CI, $25.4 million-$44.8 million). Costs also varied by trial end point, treatment duration, patient enrollment, and therapeutic area. CONCLUSIONS AND RELEVANCE The highest-cost trials were those in which the new agent had to be proved to be noninferior with clinical benefit end points compared with an agent already available or those that required larger patient populations to achieve statistical power to document smaller treatment effects or accrue infrequently occurring end points.

Abstract
A feasibility study is described involving the use of a computer program in an antenatal clinic whose decisions were based on the observed policies of the group of obstetricians running that clinic. In 200 test cases the programme successfully detected all »at risk« cases at the first visit. Abnormalities appearing at later visits were all detected and appropriate investigations ordered by the programme. The programme ordered rather more investigations than the obstetrician and this difference has been investigated, in some detail with reference to the full blood count, glucose tolerance test and the ultrasonogram.Since all of the basic data in the proposed clinic would be collected by the clerical staff or midwives, a comparison was made between two midwives and an obstetrician in estimating fundal height. The small number of discrepancies found was not regarded as serious from the viewpoint of the proposed clinic.This preliminary study suggests that the technique described might play a useful part in some areas of ante-natal care by relieving the obstetricians of much of the workload associated with routine cases and enabling the midwife to play a larger role in ante-natal care.
