Measuring Frailty Using Patient-Reported Outcomes (PRO) Data: A Feasibility Study in Patients with Multiple Myeloma.

PURPOSE: The objective of this retrospective study was to determine the feasibility of measuring frailty using patient responses to relevant EORTC QLQ-C30 items as proxy criteria for the Fried Frailty Phenotype, in a cohort of patients with Relapsed/Refractory Multiple Myeloma (RRMM). METHODS: Data were pooled from nine Phase III randomized clinical trials submitted to the FDA for regulatory review between 2010 and 2021, for the treatment of RRMM. Baseline EORTC QLQ-C30 responses were used to derive a patient-reported frailty phenotype (PRFP), based on the Fried definition of frailty. PRFP was assessed for internal consistency reliability, structural validity, and known groups validity. RESULTS: This study demonstrated the feasibility of adapting patient responses to relevant EORTC QLQ-C30 items to serve as proxy Fried frailty criteria. Selected items were well correlated with one another and PRFP as a whole demonstrated adequate internal consistency reliability and structural validity. Known groups analysis demonstrated that PRFP could be used to detect distinct comorbidity levels and distinguish between different functional profiles, with frail patients reporting more difficulty in walking about, washing/dressing, and doing usual activities, as compared to their pre-frail and fit counterparts. Among the 4928 patients included in this study, PRFP classified 2729 (55.4%) patients as fit, 1209 (24.5%) as pre-frail, and 990 (20.1%) as frail. CONCLUSION: Constructing a frailty scale from existing PRO items commonly collected in cancer trials may be a patient-centric and practical approach to measuring frailty. Additional psychometric evaluation and research is warranted to further explore the utility of such an approach.

Implementation outcomes associated with a value-based care model of comprehensive medication management in community pharmacies.

OBJECTIVE: Although the delivery of comprehensive medication management (CMM) in community pharmacies has been shown to improve health outcomes, inconsistent adoption hinders the benefit patients receive. Our objective was to examine the implementation of a novel value-based care model and the impact of educational and coaching support for pharmacists on patient access to CMM. The underlying care model provides a payment for CMM services combined with incentives to document and improve clinical outcomes and patient engagement. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: In addition to fee-for-service payments, performance-based incentives were provided to 12 participating pharmacy organizations to promote pharmacist documentation of clinical values (blood pressure and tobacco status for patients with vascular disease and additionally hemoglobin A1c [HbA1C] for patients with diabetes). To promote patient engagement, pharmacies that engaged a higher proportion of attributed patients received additional incentives. OUTCOME MEASURES: Implementation outcomes included penetration (the proportion of eligible patients who received CMM), adoption (variation in penetration across organizations), and fidelity (documentation of all required clinical values). Comparisons were made using t-tests and chi-square testing. RESULTS: Among 1240 eligible patients, 478 (35.8%) had documentation of any service by a participating pharmacist during a one-year implementation period. Using diabetes as an example, documentation was consistently highest for tobacco status (38.1%), followed by blood pressure (29.7%), and HbA1C (38.1%). CMM recipients on average were older, used more medication, and were more likely to have at least one comorbid condition than non-recipients. 41.8% of patients with vascular disease had documentation of both blood pressure and tobacco status while 24.4% of patients with diabetes had blood pressure, tobacco, and HbA1C documentation. CONCLUSIONS: Improving pharmacist access to a patient's medical records could help improve access to CMM services for patients under value-based care models that rely on patient targeting and clinical measurements.

Disparities in Medicare beneficiaries' receiving medication synchronization.

BACKGROUND: Medication synchronization (med-sync) aligns patients' monthly or quarterly chronic medications to a predetermined single pickup date at a community pharmacy. The study objective was to examine med-sync enrollment disparities based on Medicare beneficiaries' predisposing, enabling, and need characteristics. METHODS: This was a retrospective cohort study using a Medicare dataset of beneficiaries receiving medications from pharmacies that self-identified as providing med-sync. Medicare beneficiaries who were continuously enrolled in fee-for-service medical and pharmacy benefits during the study period (2014-2016) were included. Study cohorts (med-sync and non-med-sync patients) were defined, and bivariate and multivariable logistic regression analyses were performed. Andersen's Health Services Utilization Model guided our inclusion of predisposing, enabling, and need characteristics to examine for association with med-sync enrollment. RESULTS: A total of 170,180 beneficiaries were included, of which 13,193 comprised the med-sync cohort and 156,987 comprised the non-med-sync cohort. Bivariate logistic regression analysis revealed statistically significant differences (P < 0.05) in cohorts based on age, geographic region, type of residence, number of unique chronic medications, comorbidities, outpatient visits, and inpatient hospitalizations. Beneficiaries had higher odds of being enrolled in med-sync with increasing age (adjusted odds ratio [AOR] 1.003 [95% CI 1.001-1.005]) and if they resided in the Northeast (AOR 1.094 [95% CI 1.018-1.175]), South (AOR 1.109 [95% CI 1.035-1.188]), and West (AOR 1.113 [95% CI 1.020-1.215]) than those in the Midwest. Beneficiaries residing in nonmetro areas had lower odds of enrollment (AOR 0.914 [95% CI 0.863-0.969]) than those in metro areas. Beneficiaries with previous fewer inpatient hospitalizations (AOR 0.945 [95% CI 0.914-0.977]) were more likely to be enrolled, and those with more outpatient visits (AOR 1.003 [95% CI 1.001-1.004]) were more likely to be enrolled. Those taking a higher number of oral chronic medications (AOR 1.005 [95% CI 1.002-1.008]) had greater odds of enrollment in med-sync. CONCLUSIONS: Med-sync program expansion opportunities exist to address potential enrollment disparities based on age, geographic region, metropolitan area, and prior health utilization. Further studies are needed to develop and examine strategies among pharmacies to improve med-sync enrollment outreach to these subgroups of patients.

Opportunities for personalizing colorectal cancer care: an analysis of SEER-medicare data.

United States clinical practice guidelines for metastatic colorectal cancer recommend use of medications impacted by genetic variants but do not recommend testing. We analyzed real-world treatment using a cancer registry and claims dataset to explore pharmacogenomic (PGx) medication treatment patterns and characterize exposure. In a cohort of 6957 patients, most (86.9%) were exposed to at least one chemotherapy medication with PGx guidelines. In a cohort of 2223 patients with retail pharmacy claims available, most (79.2%) were treated with at least one non-chemotherapy (79.2%) medication with PGx guidelines. PGx-associated chemotherapy exposure was associated with age, race/ethnicity, educational attainment, and rurality. PGx-associated non-chemotherapy exposure was associated with medication use and comorbidities. The potential impact of PGx testing is large and policies aimed at increasing PGx testing at diagnosis may impact treatment decisions for patients with metastatic colorectal cancer as most patients are exposed to medications with pharmacogenomics implications during treatment.

An Examination of Prescribing Responsibilities between Psychiatrists and Primary Care Providers.

Patients with comorbid mental health and chronic conditions often receive care from both psychiatrists and primary care physicians (PCPs). The introduction of multiple providers into the care process introduces opportunities for disruptions in care continuity. The purpose of this study was to explore psychiatrists' and PCPs' comfort prescribing, along with their comfort having other physician specialties prescribe medications for cardiometabolic, psychiatric, and neurological/behavioral conditions. This cross-sectional study utilized an online, validated, pilot-tested, anonymous survey to examine prescribing practices of psychiatrists and PCPs. Eligible participants included physicians with medical degrees, U.S. prescribing authority, and active patient care for ≥2 days/week. Outcomes of interest were physicians' self-comfort and cross-specialty comfort (other specialists prescribing mutual patients' medications) prescribing cardiometabolic, psychiatric, and neurological/behavioral medications. Comfort prescribing was measured using 7-point Likert scales. Discrepancies in comfort were analyzed using student's, one-sample, and paired t-tests. Multiple linear regressions examined associations between physician practice characteristics and physicians' comfort-level prescribing cardiometabolic and psychiatric medication categories. Among 50 psychiatrists and 50 PCPs, psychiatrists reported significantly lower self-comfort prescribing cardiometabolic medications (mean ± SD = 2.99 ± 1.63 vs. 6.77 ± 0.39, p < 0.001), but significantly higher self-comfort prescribing psychiatric medications (mean ± SD = 6.79 ± 0.41 vs. 6.00 ± 0.88, p < 0.001) and neurological/behavioral medications (mean ± SD = 6.48 ± 0.74 vs. 5.56 ± 1.68, p < 0.001) than PCPs. After adjusting for covariates, physician specialty was strongly associated with self-comfort prescribing cardiometabolic and psychiatric medication categories (both p < 0.001). Differences between self-comfort and cross-specialty comfort were identified. Because comfort prescribing medications differed by physician type, incorporating psychiatrists through collaborative methods with PCPs could potentially ensure comfort among physicians when initiating medications.

Changes in chronic medication adherence, costs, and health care use after a cancer diagnosis among low-income patients and the role of patient-centered medical homes.

BACKGROUND: Approximately 40% of patients with cancer also have another chronic medical condition. Patient-centered medical homes (PCMHs) have improved outcomes among patients with multiple chronic comorbidities. The authors first evaluated the impact of a cancer diagnosis on chronic medication adherence among patients with Medicaid coverage and, second, whether PCMHs influenced outcomes among patients with cancer. METHODS: Using linked 2004 to 2010 North Carolina cancer registry and claims data, the authors included Medicaid enrollees who were diagnosed with breast, colorectal, or lung cancer who had hyperlipidemia, hypertension, and/or diabetes mellitus. Using difference-in-difference methods, the authors examined adherence to chronic disease medications as measured by the change in the percentage of days covered over time among patients with and without cancer. The authors then further evaluated whether PCMH enrollment modified the observed differences between those patients with and without cancer using a differences-in-differences-in-differences approach. The authors examined changes in health care expenditures and use as secondary outcomes. RESULTS: Patients newly diagnosed with cancer who had hyperlipidemia experienced a 7-percentage point to 11-percentage point decrease in the percentage of days covered compared with patients without cancer. Patients with cancer also experienced significant increases in medical expenditures and hospitalizations compared with noncancer controls. Changes in medication adherence over time between patients with and without cancer were not determined to be statistically significantly different by PCMH status. Some PCMH patients with cancer experienced smaller increases in expenditures (diabetes) and emergency department use (hyperlipidemia) but larger increases in their inpatient hospitalization rates (hypertension) compared with non-PCMH patients with cancer relative to patients without cancer. CONCLUSIONS: PCMHs were not found to be associated with improvements in chronic disease medication adherence, but were associated with lower costs and emergency department visits among some low-income patients with cancer.

Using the Drug Burden Index to identify older adults at highest risk for medication-related falls.

BACKGROUND: The Drug Burden Index (DBI) was developed to assess patient exposure to medications associated with an increased risk of falling. The objective of this study was to examine the association between the DBI and medication-related fall risk. METHODS: The study used a retrospective cohort design, with a 1-year observation period. Participants (n = 1562) were identified from 31 community pharmacies. We examined the association between DBI scores and four outcomes. Our primary outcome, which was limited to participants who received a medication review, indexed whether the review resulted in at least one medication-related recommendation (e.g., discontinue medication) being communicated to the participant's health care provider. Secondary outcomes indexed whether participants in the full sample: (1) screened positive for fall risk, (2) reported 1+ falls in the past year, and (3) reported 1+ injurious falls in the past year. All outcome variables were dichotomous (yes/no). RESULTS: Among those who received a medication review (n = 387), the percentage of patients receiving at least one medication-related recommendation ranged from 10.2% among those with DBI scores of 0 compared to 60.2% among those with DBI scores ≥1.0 (Chi-square (4)=42.4, p < 0.0001). Among those screened for fall risk (n = 1058), DBI scores were higher among those who screened positive compared to those who did not (Means = 0.98 (SD = 1.00) versus 0.59 (SD = 0.74), respectively, p < 0.0001). CONCLUSION: Our findings suggest that the DBI is a useful tool that could be used to improve future research and practice by focusing limited resources on those individuals at greatest risk of medication-related falls.

Reprint of: Examining Medicare Part D Medication Therapy Management program in the context of mental health.

OBJECTIVES: To describe and compare the delivery of medication therapy management (MTM) between Medicare beneficiaries with and without mental health conditions. DESIGN: Nationally representative cross-sectional study that used a 20% random sample of 2014 Medicare Parts A, B, and D data merged with a 100% sample of 2014 MTM data. SETTING AND PARTICIPANTS: Medicare beneficiaries continuously enrolled in Parts A, B, and D in 2014 were included in this study. Comprehensive medication review (CMR) use and MTM delivery were examined among a subset of 825,003 MTM-enrolled beneficiaries. OUTCOME MEASURES: Predisposing, enabling, and need characteristics were selected on the basis of the Andersen Behavioral Model of Health Services Use. Descriptive, bivariable, and multivariable logistic regression statistics were used to determine associations between beneficiary characteristics and MTM delivery. RESULTS: A total of 3,016,620 (43%) and 3,997,105 beneficiaries (57%) were categorized into mental health and nonmental health cohorts, respectively. MTM enrollment in the mental health cohort was significantly higher than that in the nonmental health cohort (17.4% vs. 7.5%, P < 0.001). However, once enrolled, a greater proportion of beneficiaries in the nonmental health cohort received CMRs (19.3% vs. 17.7%, P < 0.001). Patients in the mental health cohort were more likely to have hospitalization (22% vs. 9.2%, P < 0.001) or emergency department visit (25.2% vs. 11.5%, P < 0.001) and used more medications in 2014 (16 % vs. 12%, P < 0.001). The proportion of patients in the mental health cohort receiving a CMR in 2014 that had at least 1 medication-related problem (MRP) identified and resolved was higher than that of patients in the nonmental health cohort (24.8% vs. 20.6%, P < 0.001). CONCLUSION: Although patients with mental health conditions are more often enrolled into MTM, they are less likely to receive a CMR once enrolled. Given that this population has higher medical complexity and a higher MRP burden following a CMR, opportunities exist for pharmacists to enhance MTM delivery in this population.

Patient outcomes from implementing an enhanced services pharmacy network.

OBJECTIVE: To evaluate the effect of implementing a network of community pharmacies on medication adherence, health service utilization, and health care spending. DESIGN: Quasi-experimental difference-in-difference analysis with a nonequivalent control group. SETTING AND PARTICIPANTS: Eligible Medicaid-enrolled patients in North Carolina were attributed to intervention pharmacies between March 2015 and December 2016. A control group was propensity score-matched. Interventions consisted of enhanced services and a more intensive, comprehensive initial pharmacy assessment (CIPA). OUTCOME MEASURES: Outcomes included hospitalizations; emergency department (ED) visits; health care spending for total medical, inpatient, outpatient, and ED services; and adherence to renin-angiotensin system antagonists (RASA), statins, noninsulin diabetes medications (NIDM), and multiple medications for chronic conditions (MMCC). RESULTS: There were 31,509 patients who met eligibility criteria and were attributed to a participating pharmacy. Of these, 3897 received a CIPA. Before matching, patients attributed to participating pharmacies had greater Medicaid enrollment through aged, blind, or disabled status (49.2% vs. 31.5%, P < 0.001); greater case management (10.3% vs. 7%, P < 0.001); and worse rates of chronic disease (P < 0.001). Successful matching removed these differences. Adherence to RASA medications and MMCC increased by 9.5% and 10.3% (P < 0.05), respectively. Adherence did not change for statins and NIDM. The analysis also revealed a slower decline in average total medical spending of 5.7% (P < 0.01) relative to the control group over the same period, owed to a 9.6% (P < 0.001) slower decline in outpatient spending. ED utilization also decreased more slowly relative to controls by 4.8% (P < 0.05) following the intervention. CONCLUSION: The pharmacy intervention resulted in a statistically significant improvement in medication adherence to RASA and multiple chronic medications, but did not change or may have worsened utilization and spending outcomes. More research is needed to explore patient selection and variation in implementation and heterogeneity of treatment effects when evaluating pharmacy interventions.

Examining Medicare Part D Medication Therapy Management program in the context of mental health.

OBJECTIVES: To describe and compare the delivery of medication therapy management (MTM) between Medicare beneficiaries with and without mental health conditions. DESIGN: Nationally representative cross-sectional study that used a 20% random sample of 2014 Medicare Parts A, B, and D data merged with a 100% sample of 2014 MTM data. SETTING AND PARTICIPANTS: Medicare beneficiaries continuously enrolled in Parts A, B, and D in 2014 were included in this study. Comprehensive medication review (CMR) use and MTM delivery were examined among a subset of 825,003 MTM-enrolled beneficiaries. OUTCOME MEASURES: Predisposing, enabling, and need characteristics were selected on the basis of the Andersen Behavioral Model of Health Services Use. Descriptive, bivariable, and multivariable logistic regression statistics were used to determine associations between beneficiary characteristics and MTM delivery. RESULTS: A total of 3,016,620 (43%) and 3,997,105 beneficiaries (57%) were categorized into mental health and nonmental health cohorts, respectively. MTM enrollment in the mental health cohort was significantly higher than that in the nonmental health cohort (17.4% vs. 7.5%, P < 0.001). However, once enrolled, a greater proportion of beneficiaries in the nonmental health cohort received CMRs (19.3% vs. 17.7%, P < 0.001). Patients in the mental health cohort were more likely to have hospitalization (22% vs. 9.2%, P < 0.001) or emergency department visit (25.2% vs. 11.5%, P < 0.001) and used more medications in 2014 (16 % vs. 12%, P < 0.001). The proportion of patients in the mental health cohort receiving a CMR in 2014 that had at least 1 medication-related problem (MRP) identified and resolved was higher than that of patients in the nonmental health cohort (24.8% vs. 20.6%, P < 0.001). CONCLUSION: Although patients with mental health conditions are more often enrolled into MTM, they are less likely to receive a CMR once enrolled. Given that this population has higher medical complexity and a higher MRP burden following a CMR, opportunities exist for pharmacists to enhance MTM delivery in this population.

Nationwide estimates of medication therapy management delivery under the Medicare prescription drug benefit.

OBJECTIVE: To describe the national delivery of medication therapy management (MTM) to Medicare beneficiaries in 2013 and 2014. METHODS: Descriptive cross-sectional study using the 100% sample of 2013 and 2014 Part D MTM data files. We quantified descriptive statistics (counts and percentages, in addition to means and standard deviations) to summarize the delivery of these services and compare delivery between 2013 and 2014. RESULTS: Medicare beneficiaries eligible for MTM increased from 4,281,733 in 2013 to 4,552,547 in 2014. Among eligible beneficiaries, the number and percentage who were offered a comprehensive medication review (CMR) increased from 3,473,004 (81.1%) to 4,394,822 (96.5%), and beneficiaries receiving a CMR increased from 526,203 (12.3%) to 767,286 (16.9%). In 2014, CMRs were most frequently delivered by telephone (83.2%) and provided by either a plan sponsor (29.0%) or an MTM vendor in-house pharmacist (35.0%). In 2014, pharmacists provided 93.5% of all CMRs, and other providers (e.g., nurses and physicians) provided 6.5% of CMRs. Few patients who received a CMR received more than 1 within the same year (2.2% in 2014). Medication therapy problem (MTP) resolution among patients receiving a CMR stayed roughly the same between 2013 and 2014 (19.2% vs. 18.7%, respectively; P < 0.001). Finally, most beneficiaries (96.9% in 2014) received a targeted medication review, regardless of whether a CMR was offered or provided. CONCLUSION: More than 4 million Medicare beneficiaries were enrolled in Part D MTM in both 2013 and 2014. However, less than 20% of eligible beneficiaries received a CMR during those years, and rates of MTP resolution were low. Future evaluation of Part D MTM delivery should examine changes in eligibility criteria and delivery over time to inform MTM policy and changes in practice.

Characterizing and assessing antiemetic underuse in patients initiating highly emetogenic chemotherapy.

BACKGROUND: Patients initiating highly emetic chemotherapy (HEC) are at a 90% risk of chemotherapy-induced nausea and vomiting (CINV). Despite guideline-concordant antiemetic prescribing preventing CINV in up to 80% of patients, studies suggest that guideline-concordant antiemetic regimen use by patients initiating HEC is sub-optimal. However, these studies have been limited to single-site or single-cancer type with limited generalizability. The objective of this study was to describe antiemetic fill regimens and to assess predictors of underuse in the USA. METHODS: Our study population was adult patients under the age of 65 with cancer initiating intravenous HEC between 2013 and 2015 with employer-sponsored insurance in the IBM Watson/Truven MarketScan Commercial Claims database (N = 31,923). Descriptive statistics were used to explain antiemetic prescribing patterns, including antiemetic underuse. Modified Poisson regression was used to identify factors associated with antiemetic underuse. RESULTS: Among individuals initiating HEC, 49% underused guideline-concordant antiemetics. Most classified as under-using lacked an NK1 fill. While dexamethasone and 5HT3A uptake was over 80%, olanzapine use was minimal. Having lower generosity for prescription and medical benefits (paying more versus less than 20% out-of-pocket) increased the underuse risk by 3% and 4% (RR,1.03; 95% CI,1.01-1.05; P = 0.01 and RR,1.04; CI, 1.00-1.09; P = 0.03), respectively. Additionally, compared to receiving chemotherapy in the physician office setting, patients were at a 28% (RR, 1.28; 95% CI, 1.25-1.30; P < 0.0001) higher underuse risk in the outpatient hospital setting. CONCLUSION: Antiemetic underuse is high in patients initiating HEC, potentially leading to avoidable CINV events. We found that insurance generosity has a minimal effect on antiemetic guideline concordance in this population, suggesting discordance may be the result of site of care as well as gaps in provider knowledge or accountability.

Do enhanced services pharmacies serve sicker patients?

OBJECTIVES: The objective of this study was to evaluate the relationship between patients' demographics, health status, and health resource use and attribution to a pharmacy participating in an enhanced services network. METHODS: Enhanced services pharmacies were defined by participation in a North Carolina enhanced services network and an associated grant-funded payment model for enhanced services. Pharmacy enrollment in the payment model began in March of 2015. Adult, non-elderly, long-term medication users who were enrolled in Medicaid were attributed to either an enhanced services pharmacy or control pharmacy based on prescription filling patterns. Time series models were used to compare spending and resource use during the year before payment model inception. Statistical tests and standardized mean differences (SMDs) were used to compare demographics during the first 2 years of the program. RESULTS: The enhanced services cohort consisted of 250 pharmacies and 61,094 patients, and 2022 pharmacies and 414,860 patients served as controls. Compared with control patients, enhanced services patients used more medications and had worse health status at baseline. They were also older; more likely to be eligible for Medicaid via aged, blind, or disabled status and more likely to reside in a rural area (SMD > 0.2). In addition, enhanced services patients had greater mean baseline health care spending, hospital admissions, and emergency department visits (P < 0.001), but trends only differed for prescription drug spending (P < 0.05). CONCLUSION: Enhanced services pharmacies, as defined by this study, appear to serve a sicker population than control pharmacies. If validated in other studies, this phenomenon can, ironically, result in lower performance scores for pharmacies offering more extensive services. To correct for this, payers and measure developers should consider risk adjustment methods and quality improvement scores that account for variation in patient case mix and pharmacists' impact on patient health over time.

Pharmacy characteristics associated with the provision of medication management services within an integrated care management program.

OBJECTIVES: To examine pharmacy operational and personnel characteristics that influence engagement in providing a community pharmacy medication management service within a statewide integrated care management program. METHODS: Before the program launch, all of the pharmacies were surveyed to collect demographic, operational, and personnel characteristics such as weekly prescription volume and number of staff, respectively. Those data were then compared with engagement in the program. Engagement was defined as providing initial comprehensive medication review as part of the medication management service. Three months after program launch, pharmacies were dichotomized as consistently engaged or inconsistently engaged. Data were analyzed with the use of descriptive statistics and chi-square and t tests to test for statistical significance between consistent and inconsistent engagement groups. RESULTS: A baseline survey was collected for all 123 pharmacies who joined the integrated care management program. After the first 3 months, 50 pharmacies were consistently engaged in the program. Compared with inconsistently engaged pharmacies, consistently engaged pharmacies employed more full-time pharmacists (mean 2.1 vs. 1.8; P = 0.05) and more full-time technicians (mean 4.0 vs. 3.0; P <0.01), allocated more nondispensing hours for pharmacists (88% vs 60%; P <0.01), were more likely to employ a dedicated clinical pharmacist (20% vs 5%; P = 0.013), and hosted more pharmacy residents (78% vs 22%; P = 0.02). Years of pharmacy operation (P = 0.05) and pharmacy store type (P = 0.05) also were significantly associated with level of engagement. Neither prescription volume dispensed per week, number of hours of pharmacist overlap, nor hosting pharmacy students was statistically different between consistent and inconsistent pharmacies. CONCLUSION: Engagement in clinical activities in community pharmacy appears to improve with adequate staffing, availability of time for nondispensing activities, and having 1 or more pharmacists dedicated to clinical activities.

The North Carolina Experiment: Active Research in the Development and Assessment of New Practice Models.

Improving the quality of health care requires innovative approaches to addressing the misuse, overuse, and underuse of medication in the United States. Strategies must be patient-centered, collaborative, and aligned with the move toward value-based care. We highlight research in North Carolina aimed at achieving these goals.

Do medical homes increase medication adherence for persons with multiple chronic conditions?

BACKGROUND: Medications are an integral component of management for many chronic conditions, and suboptimal adherence limits medication effectiveness among persons with multiple chronic conditions (MCC). Medical homes may provide a mechanism for increasing adherence among persons with MCC, thereby enhancing management of chronic conditions. OBJECTIVE: To examine the association between medical home enrollment and adherence to newly initiated medications among Medicaid enrollees with MCC. RESEARCH DESIGN: Retrospective cohort study comparing Community Care of North Carolina medical home enrollees to nonenrollees using merged North Carolina Medicaid claims data (fiscal years 2008-2010). SUBJECTS: Among North Carolina Medicaid-enrolled adults with MCC, we created separate longitudinal cohorts of new users of antidepressants (N=9303), antihypertensive agents (N=12,595), oral diabetic agents (N=6409), and statins (N=9263). MEASURES: Outcomes were the proportion of days covered (PDC) on treatment medication each month for 12 months and a dichotomous measure of adherence (PDC>0.80). Our primary analysis utilized person-level fixed effects models. Sensitivity analyses included propensity score and person-level random-effect models. RESULTS: Compared with nonenrollees, medical home enrollees exhibited higher PDC by 4.7, 6.0, 4.8, and 5.1 percentage points for depression, hypertension, diabetes, and hyperlipidemia, respectively (P's<0.001). The dichotomous adherence measure showed similar increases, with absolute differences of 4.1, 4.5, 3.5, and 4.6 percentage points, respectively (P's<0.001). CONCLUSIONS: Among Medicaid enrollees with MCC, adherence to new medications is greater for those enrolled in medical homes.

Patterns of Pharmacological Treatment for Osteoporosis Among Patients Qualified for Pharmacotherapy According to the National Osteoporosis Foundation Guidelines.

BACKGROUND: Whereas the National Osteoporosis Foundation (NOF) guidelines suggest pharmacological treatment for patients at high risk of fractures, little is known about the prevalence of osteoporosis treatment among those who met the NOF criteria for pharmacotherapy. OBJECTIVE: To evaluate the prevalence of osteoporosis treatment among patients who met the NOF criteria and to assess factors associated with pharmacological treatment. METHODS: The 2005-2010 National Health and Nutrition Examination Survey served as the data source. Using the Fracture Risk Assessment Tool, the study included postmenopausal women and men 50 years or older who met the NOF treatment criteria. Andersen's Behavioral Model was used to select predisposing, enabling, and need factors that might predict osteoporosis treatment. A logistic regression was used to assess factors associated with osteoporosis treatment. RESULTS: An estimated 16 million individuals qualified for osteoporosis treatment according to the NOF guidelines. Only 24% of them received pharmacological treatment, and 89% of the patients receiving treatment were women. Only 6% to 12% of men who were at high risk of osteoporosis or fracture received pharmacotherapy. Older age, long-term corticosteroid use, history of fractures, and T-score ≤-2.5 were associated with increased odds of osteoporosis treatment, whereas male gender and lack of a usual source of health care were associated with decreased odds of osteoporosis treatment. CONCLUSIONS: Less than one-fourth of the population who should be considered for pharmacotherapy received osteoporosis treatment. Clinicians should be more aware of the unmet need for medication treatment for osteoporosis.

Prescriber continuity and medication adherence for complex patients.

BACKGROUND: Medication adherence is a critical aspect of managing cardiometabolic conditions, including diabetes, hypertension, dyslipidemia, and heart failure. Patients who have multiple cardiometabolic conditions and multiple prescribers may be at increased risk for nonadherence. OBJECTIVE: The purpose of this study was to examine the relationship between number of prescribers, number of conditions, and refill adherence to oral medications to treat cardiometabolic conditions. METHODS: In this retrospective cohort study, 7933 veterans were identified with 1 to 4 cardiometabolic conditions. Refill adherence to oral medications for diabetes, hypertension, and dyslipidemia was measured using an administrative claims-based continuous multiple-interval gap (CMG) that estimates the percentage of days a patient did not possess medication. We dichotomized refill adherence for each condition as a CMG ≤20% for each year of analysis. Condition-specific logistic regression models estimated the relationship between refill adherence and number of cardiometabolic conditions and number of prescribers, controlling for demographic characteristics, other comorbidities, and a count of cardiometabolic drug classes used. RESULTS: Compared with patients with 1 prescriber, antihypertensive refill adherence was lower in patients seeing ≥4 prescribers (odds ratio [OR] = 0.69; 95% CI = 0.59-0.80), but the number of cardiometabolic conditions was not a significant predictor. Antidyslipidemia refill adherence was lower in patients seeing 3 prescribers (OR = 0.80; 95% CI = 0.70-0.92) or ≥4 prescribers (OR = 0.77; 95% CI = 0.64-0.91). Conversely, antidyslipidemia refill adherence improved with the number of cardiometabolic conditions, but differences were only statistically significant for ≥3 conditions (OR = 1.31; 95% CI = 1.09-1.57). In multivariate regression models, the number of conditions and number of prescribers were not significant predictors of refill adherence in the group of patients with diabetes. CONCLUSIONS: Effective management of care and medication regimens for complex patients remains an unresolved challenge, but these results suggest that medication refill adherence might be improved by minimizing the number of prescribers involved in a patient's care, at least for hypertension and dyslipidemia.

DXA Utilization Between 2006 and 2012 in Commercially Insured Younger Postmenopausal Women.

Reimbursement for dual-energy X-ray absorptiometry (DXA) scans in the outpatient setting has declined significantly since 2006. Research through 2011 has suggested reimbursement reductions for DXA scans have corresponded with an overall decreased utilization of DXA. This study updates utilization estimates for DXAs through 2012 in patients with commercial insurance and compares DXA rates before and after reimbursement changes. We evaluated DXA utilization for women aged 50-64 yr from Marketscan Commercial Claims and Encounter database between January 2006 and December 2012 based on CPT codes. We estimated utilization rates per 1000 person years (PY). We also used segmented regression analysis of monthly rates to evaluate the change in utilization rates after a proposed reimbursement reduction in July 2009. In women aged 50-64 yr, 451,656 DXAs were performed in 2006, a rate of 144 DXAs per 1000 PY. This rate increased to 149 DXAs per 1000 PY in 2009 before decreasing to 110 DXAs per 1000 PY or 667,982 scans in 2012. DXA utilization increased by 2.24 per 1000 PY until July 2009 then declined by 12.98 DXAs per 1000 persons, resulting in 37.5 DXAs per PY fewer performed in 2012 compared with 2006. Since July 2009 a significant decline in DXA utilization occurred in a younger postmenopausal commercially insured population. This decline corresponds with a time period of reductions in Medicare DXA reimbursement.

Heterogeneity in the quality of care for patients with multiple chronic conditions by psychiatric comorbidity.

BACKGROUND: Little is known about the quality of care received by Medicaid enrollees with multiple chronic conditions (MCCs) and whether quality is different for those with mental illness. OBJECTIVES: To examine cancer screening and single-disease quality of care measures in a Medicaid population with MCC and to compare quality measures among persons with MCC with varying medical comorbidities with and without depression or schizophrenia. RESEARCH DESIGN: Secondary data analysis using a unique data source combining Medicaid claims with other administrative datasets from North Carolina's mental health system. SUBJECTS: Medicaid-enrolled adults aged 18 and older with ≥2 of 8 chronic conditions (asthma, chronic obstructive pulmonary disease, diabetes, hypertension, hyperlipidemia, seizure disorder, depression, or schizophrenia). Medicare/Medicaid dual enrollees were excluded due to incomplete data on their medical care utilization. MEASURES: We examined a number of quality measures, including cancer screening, disease-specific metrics, such as receipt of hemoglobin A1C tests for persons with diabetes, and receipt of psychosocial therapies for persons with depression or schizophrenia, and medication adherence. RESULTS: Quality of care metrics was generally lower among those with depression or schizophrenia, and often higher among those with increasing levels of medical comorbidities. A number of exceptions to these trends were noted. CONCLUSIONS: Cancer screening and single-disease quality measures may provide a benchmark for overall quality of care for persons with MCC; these measures were generally lower among persons with MCC and mental illness. Further research on quality measures that better reflect the complex care received by persons with MCC is essential.
