Arterial Biology for the Investigation of the Treatment Effects of Reducing Cholesterol (ARBITER) 2 A Double-Blind, Placebo-Controlled Study of Extended-Release Niacin on Atherosclerosis Progression in Secondary Prevention Patients Treated With Statins

Background—Niacin reduces coronary heart disease morbidity and mortality when taken either alone or in combination with statins; however, the incremental impact of adding niacin to background statin therapy is unknown. Methods and Results—This was a double-blind randomized placebo-controlled study of once-daily extended-release niacin (1000 mg) added to background statin therapy in 167 patients (mean age 67 years) with known coronary heart disease and low levels of high-density lipoprotein cholesterol (HDL-C; <45 mg/dL). The primary end point was the change in common carotid intima-media thickness (CIMT) after 1 year. Baseline CIMT (0.884±0.234 mm), low-density lipoprotein cholesterol (89±20 mg/dL), and HDL-C (40±7 mg/dL) were comparable in the placebo and niacin groups. Adherence to niacin exceeded 90%, and 149 patients (89.2%) completed the study. HDL-C increased 21% (39 to 47 mg/dL) in the niacin group. After 12 months, mean CIMT increased significantly in the placebo group (0.044±0.100 mm; P<0.001) and was unchanged in the niacin group (0.014±0.104 mm; P=0.23). Although the overall difference in IMT progression between the niacin and placebo groups was not statistically significant (P=0.08), niacin significantly reduced the rate of IMT progression in subjects without insulin resistance (P=0.026). Clinical cardiovascular events occurred in 3 patients treated with niacin (3.8%) and 7 patients treated with placebo (9.6%; P=0.20). Conclusions—The addition of extended-release niacin to statin therapy slowed the progression of atherosclerosis among individuals with known coronary heart disease and moderately low HDL-C.

Prazosin Versus Quetiapine for Nighttime Posttraumatic Stress Disorder Symptoms in Veterans An Assessment of Long-Term Comparative Effectiveness and Safety

Posttraumatic stress disorder (PTSD) is an anxiety disorder experienced by combat veterans. Nighttime symptoms are often unrelieved by selective serotonin reuptake inhibitor therapy, and increased use of prazosin or quetiapine for treatment is seen. The purpose of this study was to determine the short- and long-term effectiveness and safety of prazosin versus quetiapine for treating nighttime symptoms in veteran PTSD patients. This is a historical prospective cohort study using retrospective chart review. Three hundred twenty-four patients with a diagnosis of PTSD, based on International Classification of Diseases, Ninth Revision coding, who were initially prescribed prazosin or quetiapine for nighttime symptoms were screened for inclusion. Short-term effectiveness was determined by documentation of symptomatic improvement within 6 months, and long-term effectiveness if patients continued therapy to study end date. Safety was assessed by comparing incidence of adverse drug effects causing discontinuation of either study drug. This study included 237 patients: 62 received prazosin, and 175 received quetiapine. Short-term effectiveness was similar for prazosin (61.3%) and quetiapine (61.7%; P = 0.54). However, patients prescribed prazosin were significantly more likely to continue their therapy to study end date compared with quetiapine (48.4% vs 24%; P < 0.001; odds ratio, 3.0; 95% confidence interval, 1.62-5.45), thus achieving long-term effectiveness. Alternatively, patients in the quetiapine group were more likely to discontinue therapy because of adverse effects compared with the prazosin group (34.9% vs 17.7%; P = 0.008). Because of similar rate of short-term effectiveness, superior long-term effectiveness, and lower incidence of events leading to discontinuation, compared with quetiapine, prazosin should be used first-line for treating nighttime PTSD symptoms in a veteran population.

Improving outcomes of renal transplant recipients with behavioral adherence contracts: a randomized controlled trial.

The objective of this randomized controlled trial was to assess the effects of a 1‐year behavioral contract intervention on immunosuppressant therapy (IST) adherence and healthcare utilizations and costs among adult renal transplant recipients (RTRs). The sample included adult RTRs who were at least 1 year posttransplant, taking tacrolimus or cyclosporine and served by a specialty pharmacy. Pharmacy refill records were used to measure adherence and monthly questionnaires were used to measure healthcare utilizations. Direct medical costs were estimated using the 2009 Medicare Expenditure Panel Survey. Adherence was analyzed using the GLM procedure and the MIXED procedure of SAS. Rate ratios and 95% confidence intervals were estimated to quantify the rate of utilizing healthcare services relative to treatment assignment. One hundred fifty RTRs were enrolled in the study. Intervention group RTRs (n = 76) had higher adherence than control group RTRs (n = 74) over the study period (p < 0.01). And 76.1% of the intervention group compared with 42.7% of the control group was not hospitalized during the 1‐year study period (RR = 1.785; 95% CI: 1.314, 2.425), resulting in cost savings. Thus, evidence supports using behavioral contracts as an effective adherence intervention that may improve healthcare outcomes and lower costs.

A Systematic Review of Economic Studies on Biological Agents Used to Treat Crohn’s Disease

Background:Identifying clinical scenarios that maximize the cost-effectiveness of biological treatments can lead to optimized health care cost-saving and clinical effectiveness from a society’s perspective. Methods:Published articles between January 1995 and June 2012 were searched in PubMed, EMBASE, ABI/INFORM, Tuft’s Cost-Effectiveness Analysis Registry Database, Cochrane National Health Service Economic Evaluation Database, International Pharmaceutical Abstracts, Web of Science, and Google Scholar. Studies of interest included the following: (1) cost studies, (2) economic evaluations, or (3) narrative or systematic reviews related to economic evaluations of biological treatments for moderate-to-severe Crohn’s disease (CD). The primary outcomes of interest included costs associated with biological treatments and cost-effectiveness measures, including incremental cost-effectiveness ratios. A threshold of

Cost‐Utility Analysis of Biologic Treatments for Moderate‐to‐Severe Crohn's Disease

100,000/quality-adjusted life year (£60,000/quality-adjusted life year) gained was used for treatment cost-effectiveness. Results:Thirty-eight studies were identified, including 15 economic evaluations and 23 cost studies or reviews of economic evaluations. Economic evaluations found that infliximab and adalimumab were more cost-effective than standard therapy for luminal CD when provided as an induction therapy followed by episodic therapy over 5 or more years. The cost-effectiveness of infliximab and adalimumab versus standard therapy for luminal CD was less certain when used as 1-year maintenance treatment with or without previous induction therapy. Cost studies revealed that infliximab therapy reduced health care resource utilization and cost. Older reviews were inconclusive about the cost-effectiveness of biological treatments used for CD. Conclusions:Current evidence suggests that biological treatments may be cost-effective for CD under certain clinical scenarios. Future studies evaluating all biological treatments are needed to compare their respective benefits and costs.

Interprofessional Competencies in Integrative Primary Healthcare

PURPOSE The findings from the observational studies comparing the effectiveness and safety of non-vitamin K antagonist oral anticoagulants (NOACs) versus vitamin K antagonists (VKAs) for atrial fibrillation (AF) and venous thromboembolism (VTE) are inconsistent. We conducted separate meta-analyses examining the efficacy/effectiveness and safety of NOACs versus VKAs by disease (AF vs VTE), study design (randomized controlled trials [RCTs] vs observational studies), and NOAC (dabigatran, rivaroxaban, apixaban, and edoxaban). METHODS The main data sources included PubMed/MEDLINE, EMBASE, Web of Science, CINAHL, and Scopus from January 1, 2005, to February 15, 2016. We searched for Phase III RCTs and observational studies comparing NOACs versus VKAs. The primary outcomes were stroke/systemic embolism (SE) for AF; recurrent VTE/fatal pulmonary embolism (PE) for VTE; and major bleeding for both conditions. Secondary outcomes included stroke and myocardial infarction (MI) for AF, recurrent deep vein thrombosis (DVT)/PE for VTE, and mortality, intracranial hemorrhage (ICH), and gastrointestinal bleeding for both conditions. Pooled hazard ratios (HRs) were reported by using inverse variance-weighted random effects models. FINDINGS A total of 13 RCTs and 27 observational studies (AF, n = 32; VTE, n = 8) were included. For AF, dabigatran and VKAs were comparable for stroke/SE risk in 1 RCT (HR, 0.77 [95% CI, 0.57-1.03]) and 6 observational studies (HR, 1.03 [95% CI, 0.83-1.27]). Rivaroxaban had a 20% decreased risk of stroke/SE in 3 RCTs (HR, 0.80 [95% CI, 0.67-0.95]) compared with VKA, but the effect was nonsignificant in 3 observational studies (HR, 0.78 [95% CI, 0.59-1.04]). Apixaban decreased stroke/systemic embolism risk (HR, 0.79 [95% CI, 0.66-0.95]) compared with VKA in 1 RCT, but edoxaban was comparable to VKA (HR, 0.99 [95% CI, 0.77-1.28]) in 1 RCT (no observational studies available for apixaban/edoxaban). Dabigatran, apixaban, and edoxaban decreased the risk of hemorrhagic stroke, mortality, major bleeding, and ICH by 10% to 71% compared with VKAs but not rivaroxaban. For VTE, NOACs and VKAs were comparable for recurrent VTE/fatal PE/DVT/PE risk in 7 RCTs and 1 observational study. The 7 RCTs demonstrated a 32% to 69% decreased risk of major bleeding for dabigatran, rivaroxaban, and apixaban compared with VKAs. No difference was shown in 1 rivaroxaban observational study (HR, 0.77 [95% CI, 0.40-1.49]) and 1 edoxaban RCT (HR, 0.84 [95% CI, 0.59-1.20]). Except for dabigatran, the NOACs had a 61% to 86% decreased risk of ICH and gastrointestinal bleeding. IMPLICATIONS Overall, NOACs were comparable or superior to VKAs. Although no observational studies are currently available for apixaban/edoxaban, a few notable inconsistencies exist for dabigatran (ischemic stroke, MI) and rivaroxaban (stroke/SE, major bleeding in VTE) between RCTs and observational studies. Individualizing NOAC/VKA therapy based on benefit/safety profiles and patient characteristics is suggested.

Cost-effectiveness of biological agents used in ulcerative colitis

In October 2014, the National Center for Integrative Primary Healthcare (NCIPH) was launched as a collaboration between the University of Arizona Center for Integrative Medicine and the Academic Consortium for Integrative Health and Medicine and supported by a grant from the Health Resources and Services Administration. A primary goal of the NCIPH is to develop a core set of integrative healthcare (IH) competencies and educational programs that will span the interprofessional primary care training and practice spectra and ultimately become a required part of primary care education. This article reports on the first phase of the NCIPH effort, which focused on the development of a shared set of competencies in IH for primary care disciplines. The process of development, refinement, and adoption of 10 “meta-competencies” through a collaborative process involving a diverse interprofessional team is described. Team members represent nursing, the primary care medicine professions, pharmacy, public health, acupuncture, naturopathy, chiropractic, nutrition, and behavioral medicine. Examples of the discipline-specific sub-competencies being developed within each of the participating professions are provided, along with initial results of an assessment of potential barriers and facilitators of adoption within each discipline. The competencies presented here will form the basis of a 45-hour online curriculum produced by the NCIPH for use in primary care training programs that will be piloted in a wide range of programs in early 2016 and then revised for wider use over the following year.

Impact of Diabetes Care by Pharmacists as Part of Health Care Team in Ambulatory Settings: A Systematic Review and Meta-analysis:

Ulcerative colitis (UC) produces bloody diarrhoea, severe abdominal pain, and need for clinic visits, hospitalizations, and surgeries. UC results in reduced health-related quality of life for patients and large direct medical and indirect costs for health systems and employers. Patients with the most severe disease require the most medical services, and these patients have larger costs than patients with mild or moderate disease. Despite biological therapies being quite expensive, they are indicated for patients unresponsive to initial standard therapies. Future hospitalizations may be reduced by starting a biological treatment. Cost-effectiveness results vary between countries, health systems, and model designs. Since restorative proctocolectomy can be curative, this surgery dominates biological therapy by being both less costly and more effective when measuring health system costs and patient quality-adjusted life years for 20 years. However the dose, duration, and effectiveness of biological treatments significantly impact estimates of their cost-effectiveness.

Optimizing pharmacotherapy in elderly patients: the role of pharmacists

Objective: To conduct a comprehensive systematic review and meta-analyses examining the impact of pharmacist interventions as part of health care teams on diabetes therapeutic outcomes in ambulatory care settings. Data Sources: PubMed/MEDLINE, EMBASE, Cochrane Library, International Pharmaceutical Abstracts, Web of Science, Scopus, WHO’s Global Health Library, ClinicalTrials.gov, and Google Scholar were searched (1995 to February 2017). Search terms included pharmacist, team, and diabetes. Study Selection: Full-text articles published in English with comparative designs, including randomized controlled trials, nonrandomized controlled trials, and pretest-posttest studies evaluating hemoglobin A1C (A1C), were assessed. Data Extraction and Synthesis: Two reviewers independently screened for study inclusion and extracted data. Quality of the studies was assessed using tools developed based on the framework of the Cochrane Collaboration’s recommendations. Data Synthesis: A total of 1908 studies were identified from the literature and reference searches; 42 studies were included in the systematic review (n = 10 860) and 35 in the meta-analyses (n = 7417). Mean age ranged from 42 to 73 years, and 8% to 100% were male. The overall standardized mean difference (SMD) for A1C for pharmacist care versus comparison was 0.57 (P < 0.01), a moderate effect representing a mean difference of 1.1% (95% CI = 0.88-1.27). The effects for systolic blood pressure and low-density lipoprotein cholesterol were between small and moderate (SMD = 0.31 and 0.32; P < 0.01). The heterogeneity was high for all outcomes (>83%), indicating functional differences among the studies. No publication bias was detected. Conclusion: Pharmacists’ interventions as part of the patient’s health care team improved diabetes therapeutic outcomes, substantiating the important role of pharmacists in team-based diabetes management.
