BackgroundMail order pharmacy (MOP) use has been linked to improved medication adherence and health outcomes among patients with diabetes. However, no large-scale intervention studies have assessed the effect of encouraging MOP use on medication adherence.ObjectiveTo assess an intervention to encourage MOP services to increase its use and medication adherence.DesignRandomized encouragement trial.Patients63,012 diabetes patients from three health care systems: Kaiser Permanente Northern California (KPNC), Kaiser Permanente Hawaii (KPHI), and Harvard Pilgrim Health Care (HPHC) who were poorly adherent to at least one class of cardiometabolic medications and had not used MOP in the prior 12 months.InterventionPatients were randomized to receive either usual care (control arm) or outreach encouraging MOP use consisting of a mailed letter, secure email message, and automated telephone call outlining the potential benefits of MOP use (intervention arm). HPHC intervention patients received the letter only.MeasurementsWe compared the percentages of patients that began using MOP and that became adherent to cardiometabolic medication classes during a 12-month follow-up period. We also conducted a race/ethnicity-stratified analysis.ResultsDuring follow-up, 10.6% of intervention patients began using MOP vs. 9.3% of controls (p

BackgroundMedication non-adherence is a major contributor to poor outcomes in diabetes. Previous research has shown an association between use of mail order pharmacy delivery and better medication adherence, but little is known about the barriers and facilitators to mail order pharmacy use in diabetes patients. This qualitative study examined factors related to mail order pharmacy use versus traditional "brick and mortar" pharmacies to refill prescriptions.MethodsWe conducted four 90-min focus groups in 2016 among 28 diabetes patients in the Hawaii and Northern California regions of Kaiser Permanente, a large integrated health care delivery system. We queried participants on their preferred mode for refilling prescriptions and perceived barriers and facilitators of mail order pharmacy use. One researcher independently coded each focus group transcript, with two of these transcripts double-coded by a second researcher to promote reliability. We employed thematic analysis guided by the Capability, Opportunity, Motivation, and Behavior (COM-B) framework using NVivo 11 software.ResultsA total of 28 diabetes patients participated. Participants' average age was 64.1 years; 57% were female; and racial/ethnic backgrounds included Asian/Native Hawaiian/Pacific Islander (36%), Black/African-American (21%) Hispanic/Latino (7%), and non-Hispanic White (36%). Analysis uncovered 26 themes related to the decision to use mail order pharmacy, with each theme representing a barrier or facilitator mapped to the COM-B framework. Most themes (20/26) fell into the COM-B category of 'Opportunity.' Opportunity barriers to mail order pharmacy use included unpredictability of medication delivery date, concerns about mail security, and difficulty coordinating refill orders for multiple prescriptions. In contrast, facilitators included greater access and convenience (e.g., no need to wait in line or arrange transportation) compared to traditional pharmacies. Motivational facilitators to mail order pharmacy use included receiving a pharmacy benefit plan incentive of a free one-month supply of prescriptions.ConclusionsThis study found that while patients with diabetes may benefit from mail order pharmacy use, they perceive numerous barriers to using the service. These findings will inform the design of interventions and quality improvement initiatives to increase mail order pharmacy use, which in turn may improve medication adherence and outcomes in diabetes patients, across health care systems.

OBJECTIVE: To examine the association between preventive drug lists (PDLs) and changes in medication costs among patients with diabetes insured in commercial health plans over 2 follow-up years. RESEARCH DESIGN AND METHODS: We conducted a quasiexperimental study using the Optum deidentified Clinformatics Data Mart Database (January 2003 to December 2017). The intervention group included 5,582 patients with diabetes age 12–64 years switched by employers to PDL coverage; the control group included 5,582 matched patients whose employers offered no PDL. Outcomes included out-of-pocket costs, standardized costs, and 30-day fills for all medications because PDL-associated savings could be used to pay for medicines in other classes and for five therapeutic classes covered by the PDLs (oral diabetes medications, insulins, test strips, antihypertensive drugs, and lipid-lowering drugs). RESULTS: Pre– to post–out-of-pocket spending for all medications declined by 29.7% in follow-up year 2 (95% CI −36.0, −23.4%) among PDL members relative to control individuals. Higher-income and lower-income PDL members experienced significant reductions in out-of-pocket spending for all medications in year 2 (30%) and for key therapeutic classes (range −23 to −67%). We found significant increases in use of key therapeutic classes in the overall population (range 8–15%) and in higher-income and lower-income PDL members (range 9–50%). CONCLUSIONS: PDLs offer an effective strategy for employers and insurers to lower member cost sharing and encourage increased use of important medications to prevent or manage chronic illnesses. For patients with diabetes, especially those with lower incomes, PDL coverage resulted in substantial and persistent reductions in out-of-pocket medication costs, medication use increases, and some increased use of more expensive products.

PurposeHigher mortality after a breast cancer diagnosis has been observed among women who are obese. We investigated the relationships between body mass index (BMI) and all-cause or breast cancer-specific mortality after a diagnosis of locoregional breast cancer.MethodsWomen diagnosed in 2004 with AJCC Stage I, II, or III breast cancer (n = 5394) were identified from a population-based National Program of Cancer Registries (NPCR) patterns of care study (POC-BP) drawing from registries in seven U.S. states. Differences in overall and breast cancer-specific mortality were investigated using Cox proportional hazards regression models adjusting for demographic and clinical covariates, including age- and stage-based subgroup analyses.ResultsIn women 70 or older, higher BMI was associated with lower overall mortality (HR for a 5 kg/m2 difference in BMI = 0.85, 95% CI 0.75-0.95). There was no significant association between BMI and overall mortality for women under 70. BMI was not associated with breast cancer death in the full sample, but among women with Stage I disease; those in the highest BMI category had significantly higher breast cancer mortality (HR for BMI ≥ 35 kg/m2 vs. 18.5-24.9 kg/m2 = 4.74, 95% CI 1.78-12.59).ConclusionsContrary to our hypothesis, greater BMI was not associated with higher overall mortality. Among older women, BMI was inversely related to overall mortality, with a null association among younger women. Higher BMI was associated with breast cancer mortality among women with Stage I disease, but not among women with more advanced disease.

The effects of the adenine analogue, 4-aminopyrazolopyrimidine, on lipid metabolism in mouse liver have been studied in an attempt to ascertain the mechanism by which this drug causes fatty livers. Injection of I mg of APP caused an increase in the total liver lipid of 3- to 4-fold in 24 hr, which was almost entirely accounted for as neutral lipid. There was a small increase in the cholesterol content of treated livers, but no change in the amount of phospholipid. Treatment with APP inhibited the incorporation of acetate-C14 into lipids of liver slices in vitro, but had little effect on the oxidation of acetate-C14 and palmitate-C14 in vitro. The plasma lipid concentration was decreased by APP treatment, and this was caused by a drop in triglycerides and cholesterol, whereas phospholipids and FFA did not change. Palmitate-C14 was taken up less well by livers of mice treated with APP than by livers of control mice. Although APP caused a profound inhibition of incorporation of orotic acid-C14 into RNA, the incorporation of glycine-C14 Into liver and plasma proteins was not diminished. The hyperlipemia normally elicited by Triton WR-1339 was inhibited by APP, which strongly suggests that this compound inhibits the secretion of triglycerides from the liver.

PURPOSE OF REVIEW:Diabetes incidence is rising among vulnerable population subgroups including minorities and individuals with limited education. Many diabetes-related programs and public policies are unevaluated while others are analyzed with research designs highly susceptible to bias which can result in flawed conclusions. The Natural Experiments for Translation in Diabetes 2.0 (NEXT-D2) Network includes eight research centers and three funding agencies using rigorous methods to evaluate natural experiments in health policy and program delivery. RECENT FINDINGS:NEXT-D2 research studies use quasi-experimental methods to assess three major areas as they relate to diabetes: health insurance expansion; healthcare financing and payment models; and innovations in care coordination. The studies will report on preventive processes, achievement of diabetes care goals, and incidence of complications. Some studies assess healthcare utilization while others focus on patient-reported outcomes. NEXT-D2 examines the effect of public and private policies on diabetes care and prevention at a critical time, given ongoing and rapid shifts in the US health policy landscape.

Objective Study Setting and Design Data Sources and Analytic Sample Principal Findings Conclusions To examine how a novel payer‐provider joint venture (JV) between one payer and multiple competitive delivery systems in New Hampshire (NH), which included value‐based payment, care management, and non‐financial supports, impacted healthcare value and payer and provider group experiences.We conducted a mixed‐methods study. We used a quasi‐experimental longitudinal difference‐in‐differences design to examine the impact of the JV (which started in January 2016 and ended in December 2020) on healthcare utilization, quality, and spending, using members in Maine (ME) as a control group. We also analyzed patient uptake of the JV's care management program using routinely collected administrative data and assessed payer and provider group leaders' perspectives about the JV via semi‐structured interviews.We used administrative and claims data from 2013 to 2019 in a commercially insured population under 65 years in NH and ME. We also used administrative data on care management eligibility and uptake and conducted semi‐structured interviews with payer and provider group leaders affiliated with the JV.The JV was associated with no sustained change in medical utilization, quality, and spending throughout the study period. In the first year of the JV, there was a $142 (95% confidence interval: $41, $243) increase in pharmaceutical spending per member and a 13% (4.4%, 25%) relative increase in days covered for diabetes medications. Only 15% of eligible members engaged in care management, which was a key component of the JV's multi‐pronged approach. In a disconnect from the empirical findings, payer and provider group leaders believed that the JV reduced healthcare costs and improved quality.Our findings provide evidence for future payer‐provider JVs and demonstrate the importance of having a valid control group when evaluating JVs and value‐based payment arrangements.

Background: To develop and validate a novel administration device for holmium-166 transarterial radioembolisation (TARE) with the purpose of facilitating controlled fractional microsphere administration for a more flexible and image-guided TARE procedure. Methods: A Controlled Administration Device (CAD) was developed using MR-conditional materials. The CAD contains a rotating syringe to keep the microspheres in suspension during administration. Different rotational speeds were tested ex vivo to optimise the homogeneity of microsphere fractions administered from the device. The technical performance, accuracy, and safety was validated in three patients in a clinical TARE setting by administering a standard clinical dose in 5 fractions (identifier: NCT05183776). MRI-based dosimetry was used to validate the homogeneity of the given fractions in vivo, and serious adverse device event ((S)A(D)E) reporting was performed to assess safety of the CAD. Results: A rotational speed of 30 rpm resulted in the most homogeneous microsphere fractions with a relative mean deviation of 1.1% (range: -9.1-8.0%). The first and last fraction showed the largest deviation with a mean of -26% (std. 16%) and 7% (std. 13%). respectively. In the three patient cases the homogeneity of the microsphere fractions was confirmed given that MRI-based dosimetry showed near linear increase of mean absorbed target liver dose over the given fractions with R2 values of 0.98, 0.97 and 0.99. No (S)A(D)E's could be contributed to the use of the CAD. Conclusions: The newly developed CAD facilitates safe and accurate fractional microsphere administration during TARE, and can be used for multiple applications in the current and future workflows of TARE.

Inflammatory breast cancer (IBC) is a rare yet aggressive form of breast cancer. We examined differences in patient demographics and outcomes in IBC compared to locally advanced breast cancer (LABC) and all other breast cancer patients from the Breast and Prostate Cancer Data Quality and Patterns of Care Study (POC-BP), containing information from cancer registries in seven states. Out of 7,624 cases of invasive carcinoma, IBC and LABC accounted for 2.2% (N = 170) and 4.9% (N = 375), respectively. IBC patients were more likely to have a higher number (P = 0.03) and severity (P = 0.01) of comorbidities than other breast cancer patients. Among IBC patients, a higher percentage of patients with metastatic disease versus nonmetastatic disease were black, on Medicaid, and from areas of higher poverty and more urban areas. Black and Hispanic IBC patients had worse overall and breast cancer-specific survival than white patients; moreover, IBC patients with Medicaid, patients from urban areas, and patients from areas of higher poverty and lower education had worse outcomes. These data highlight the effects of disparities in race and socioeconomic status on the incidence of IBC as well as IBC outcomes. Further work is needed to reveal the causes behind these disparities and methods to improve IBC outcomes.
