Fat Modulates the Relationship between Sarcopenia and Physical Function in Nonobese Older Adults
It is intuitive to think that sarcopenia should be associated with declines in physical function though recent evidence questions this assertion. This study investigated the relationship between absolute and relative sarcopenia, with physical performance in 202 nonobese (mean BMI = 26.6 kg/ht2) community-dwelling older (mean age = 73.8 ± 5.9
years) adults. While absolute sarcopenia (appendicular skeletal mass (ASM)/ht2) was either not associated, or weakly associated with physical performance, relative sarcopenia (ASM/kg) demonstrated moderate (r = 0.31 to r = 0.51, P < 0.01) relationships with performance outcomes in both males and females. Knee extension strength (r = 0.27) and leg extension power (r = 0.41) were both related to absolute sarcopenia (P < 0.001) in females and not in males. Strength and power were associated with relative sarcopenia in both sexes (from r = 0.47 to r = 0.67, P < 0.001). The ratio of lean mass to total body mass, that is, relative sarcopenia, is an important consideration relative to physical function in older adults even in the absence of obesity. Stratifying these individuals into equal tertiles of total body fat revealed a trend of diminished regression coefficients across each incrementally higher fat grouping for performance measures, providing further evidence that total body fat modulates the relationship between sarcopenia and physical function
Chapter Value-Based Evaluation of Chinese Provincial Health Insurance Policy Schemes
Since 2011, an international group of health policy experts has been working on a value-framework to be used for pharmaceutical policy decisions based on multicriteria decision analysis (MCDA). This tool can be easily adapted to a local decision-making context through a facilitated workshop format. Several workshops have been conducted in emerging markets to test the acceptance and feasibility of using MCDA in local decision-making. In China, national policy goals for expanding health-care coverage pressure the provincial governments to implement more comprehensive coverage schemes. This chapter demonstrates the adaptation of a global value-framework to the local policy environment. In September 2018, nine leaders from provincial health insurance bureaus responsible for the urban employee basic medical insurance (UEBMI) participated in a 1-day workshop to build a consensus on the most important objectives for the health-care reform and to translate these into measurable criteria. The participants ranked the criteria by importance and MCDA methodology was used for weighing the importance of each criterion in the final decision. The model driving this process will be presented and discussed by comparing two policy options for health-care reform

Assessment of COPD-related outcomes via a national electronic medical record database
Carl Asche, Qayyim Said, Vijay Joish, Charles Oaxaca Hall, Diana BrixnerPharmacotherapy Outcomes Research Center, Department of Pharmacotherapy, University of Utah College of Pharmacy, Salt Lake City, UT, USAPurpose: The technology and sophistication of healthcare utilization databases have expanded over the last decade to include results of lab tests, vital signs, and other clinical information. This review provides an assessment of the methodological and analytical challenges of conducting chronic obstructive pulmonary disease (COPD) outcomes research in a national electronic medical records (EMR) dataset and its potential application towards the assessment of national health policy issues, as well as a description of the challenges or limitations.Methods: An EMR database and its application to measuring outcomes for COPD are described. The ability to measure adherence to the COPD evidence-based practice guidelines, generated by the NIH and HEDIS quality indicators, in this database was examined. Case studies, before and after their publication, were used to assess the adherence to guidelines and gauge the conformity to quality indicators.Results: EMR was the only source of information for pulmonary function tests, but low frequency in ordering by primary care was an issue. The EMR data can be used to explore impact of variation in healthcare provision on clinical outcomes. The EMR database permits access to specific lab data and biometric information.Conclusions: The richness and depth of information on &ldquo;real world&rdquo; use of health services for large population-based analytical studies at relatively low cost render such databases an attractive resource for outcomes research. Various sources of information exist to perform outcomes research. It is important to understand the desired endpoints of such research and choose the appropriate database source.

Considering Multicriteria Decision Analysis (MCDA) Simple Scoring as an Evidence-Based HTA Methodology for Evaluating Off-Patent Pharmaceuticals (OPPs) in Emerging Markets
Off-patent pharmaceuticals (OPPs) represent more than 60% of the pharmaceutical market in many emerging countries, where they are frequently evaluated primarily on cost rather than with health technology assessment. OPPs are assumed to be identical to the originators. Branded and unbranded generic versions can, however, vary from the originator in active pharmaceutical ingredients, dosage, consistency formulation, excipients, manufacturing processes, and distribution, for example. These variables can alter the efficacy and safety of the product, negatively impacting both the anticipated cost savings and the population?s health. In addition, many health care systems lack the resources or expertise to evaluate such products, and current assessment methods can be complex and difficult to adapt to a health system?s needs. Multicriteria decision analysis (MCDA) simple scoring is an evidence-based health technology assessment methodology for evaluating OPPs, especially in emerging countries in which resources are limited but decision makers still must balance affordability with factors such as drug safety, level interchangeability, manufacturing site and active pharmaceutical ingredient quality, supply track record, and real-life outcomes. MCDA simple scoring can be applied to pharmaceutical pricing, reimbursement, formulary listing, and drug procurement. In November 2015, a workshop was held at the International Society for Pharmacoeconomics and Outcomes Research Annual Meeting in Milan to refine and prioritize criteria that can be used in MCDA simple scoring for OPPs, resulting in an example MCDA process and 22 prioritized criteria that health care systems in emerging countries can easily adapt to their own decision-making processes
Nine years of comparative effectiveness research education and training: initiative supported by the PhRMA Foundation
The term comparative effectiveness research (CER) took center stage with passage of the American Recovery and Reinvestment Act (2009). The companion US$1.1 billion in funding prompted the launch of initiatives to train the scientific workforce capable of conducting and using CER. Passage of the Patient Protection and Affordable Care Act (2010) focused these initiatives on patients, coining the term ‘patient-centered outcomes research’ (PCOR). Educational and training initiatives were soon launched. This report describes the initiative of the Pharmaceutical Research and Manufacturers Association of America (PhRMA) Foundation. Through provision of grant funding to six academic Centers of Excellence, to spearheading and sponsoring three national conferences, the PhRMA Foundation has made significant contributions to creation of the scientific workforce that conducts and uses CER/PCOR
Implication of alternative minimal clinically important difference threshold estimation on technology assessment
Participation in an innovative patient support program reduces prescription abandonment for adalimumab-treated patients in a commercial population.
Purpose: Nonadherence to indicated therapy reduces treatment effectiveness and may increase cost of care. HUMIRA Complete, a Patient Support Program (PSP), aims to reduce nonadherence in patients prescribed adalimumab (ADA). The objective of this study was to assess the relationship between participation in the PSP and prescription abandonment rates among ADA-treated patients.
Patients and methods: This longitudinal study using patient-level data from AbbVie\u27s PSP linked with medical and pharmacy claims data included patients ≥18 years with an ADA-approved indication, ≥1 pharmacy claim for ADA, and available data ≥3 months before and ≥6 months after the index date (defined as the initial ADA claim [01/2015 to 02/2017]). Abandonment was defined as reversal of initial ADA prescription with no paid claim during 3-month follow-up. Abandonment rates were compared between PSP and non-PSP cohorts using multivariable logistic regression controlling for potentially confounding baseline characteristics.
Results: In 17,371 patients (9,851 PSP; 7,520 non-PSP), the overall abandonment rate was 10.8-16.8% across indications. The odds of ADA abandonment were 70% less for PSP vs non-PSP patients (5.6% vs 20.4%, odds ratio [OR]=0.30, [95% confidence interval (CI)=0.27-0.33]
Conclusion: Participation in the PSP, higher income, and using a specialty pharmacy were associated with lower odds of abandoning ADA therapy, whereas increased copayments were associated with greater abandonment. PSPs should be considered to improve initiation of ADA therapy
Algorithms to identify COPD in health systems with and without access to ICD coding: a systematic review
Background
Chronic obstructive pulmonary disease (COPD) causes significant morbidity and mortality worldwide. Estimation of incidence, prevalence and disease burden through routine insurance data is challenging because of under-diagnosis and under-treatment, particularly for early stage disease in health care systems where outpatient International Classification of Diseases (ICD) diagnoses are not collected. This poses the question of which criteria are commonly applied to identify COPD patients in claims datasets in the absence of ICD diagnoses, and which information can be used as a substitute. The aim of this systematic review is to summarize previously reported methodological approaches for the identification of COPD patients through routine data and to compile potential criteria for the identification of COPD patients if ICD codes are not available.
Methods
A systematic literature review was performed in Medline via PubMed and Google Scholar from January 2000 through October 2018, followed by a manual review of the included studies by at least two independent raters. Study characteristics and all identifying criteria used in the studies were systematically extracted from the publications, categorized, and compiled in evidence tables.
Results
In total, the systematic search yielded 151 publications. After title and abstract screening, 38 publications were included into the systematic assessment. In these studies, the most frequently used (22/38) criteria set to identify COPD patients included ICD codes, hospitalization, and ambulatory visits. Only four out of 38 studies used methods other than ICD coding. In a significant proportion of studies, the age range of the target population (33/38) and hospitalization (30/38) were provided. Ambulatory data were included in 24, physician claims in 22, and pharmaceutical data in 18 studies. Only five studies used spirometry, two used surgery and one used oxygen therapy.
Conclusions
A variety of different criteria is used for the identification of COPD from routine data. The most promising criteria set in data environments where ambulatory diagnosis codes are lacking is the consideration of additional illness-related information with special attention to pharmacotherapy data. Further health services research should focus on the application of more systematic internal and/or external validation approaches
