Completion of recommended tests and referrals in telehealth vs in-person visits.
The purpose of this retrospective cohort study was to explore the prevalence of diagnostic loop closure for tests and referrals ordered at telehealth visits when compared to in-person visits and characterize related factors. The study included test and referral orders for 4,133 patients A total 27.8% of the orders were placed during a telehealth visit. The study found that of the telehealth orders, 42.6% were completed within the designated time frame vs 58.4% of those ordered during in-person visits and 57.4% of those ordered without a visit. In an adjusted analysis, when compared with patients with in persons visits, patients with telehealth visits were less likely to close the loop for all test types.

Telephone-based social health screening by pharmacists in the nonadherent Medicare population.
The study examined social health needs among Medicare patients and pharmacist-led screening's impact on medication adherence and healthcare use. Using a predictive algorithm, higher-risk patients were identified. Patients accepting referrals had better statin adherence, while those declining had more hospital stays and fewer primary care visits. The findings suggest pharmacist interventions can improve medication adherence without worsening healthcare use or plan membership.

County-level barriers in the COVID-19 vaccine coverage index and their associations with willingness to receive the COVID-19 vaccine across racial/ethnic groups in the U.S.
This study examined whether county-level vaccination barriers varied across racial/ethnic groups in the U.S., if they were associated with willingness to receive the COVID-19 vaccine, and if they differed across racial/ethnic groups. Data was taken from the REACH-US study. County-level vaccination barriers were measured using the COVID-19 Vaccine Coverage Index. Results showed that American Indian/Alaska Native, African American, Hispanic/Latino, and Multiracial adults were more likely than White adults to live in counties with higher overall county-level vaccination barriers. Higher sociodemographic barriers were associated with less willingness to receive the COVID-19 vaccine. History of low vaccination was associated with less willingness to receive the COVID-19 vaccine among African American adults. The researchers concluded that future vaccination programs should include efforts accounting for structural barriers to preventive healthcare and their intersection with sociodemographic factors.

Comparative adherence trajectories of oral disease-modifying agents in multiple sclerosis.
This study’s objective was to compare the adherence trajectories of fingolimod (FIN), teriflunomide (TER), and dimethyl fumarate (DMF) users with multiple sclerosis (MS) as there is limited evidence regarding the comparative adherence patterns of different oral disease-modifying agents (DMAs). The authors used data from the IBM MarketScan Commercial Claims Database from 2015 to 2019. The study cohort included adults (≥18 years) with MS (International Classification of Diseases [ICD]-9/10-Clinical Modification [CM]:340/G35) diagnosis and ≥1 DMA prescription. 1913 patients with MS who were initiated with FIN (24.2%, n = 462), TER (24.0%, n = 458), and DMF (51.9%, n = 993) during 2016-2018 were included. The adherence rate among FIN, TER, and DMF users was found to be 70.8% (n = 327), 59.6% (n = 273), and 61.0% (n = 606), respectively. The Group-Based Trajectory Modeling (GBTM) grouped patients into three adherence trajectories: Complete Adherers-59.1%, Slow Decliners-22.6%, and Rapid Discontinuers-18.3%. DMF and TER users had higher odds to be rapid discontinuers than FIN users. In addition, TER users were more likely to be slow decliners compared with FIN users.

Pharmacist-led, checklist intervention did not improve adherence in ambulatory patients starting/resuming DOACs.
This study’s aim was to determine whether checklist-driven care from a clinical pharmacist improved adherence in ambulatory patients starting a direct-acting anticoagulant (DOAC) or resuming it after a setback (thromboembolic event or bleeding) in an ambulatory setting. Clinical pharmacists using the DOAC checklist verified DOAC appropriateness, instructed dose de-escalation, educated through 3 tele-visits, fielded hotline calls, and handed off to a continuity provider after 3 months. Coupons and help with completing manufacturer-based medication assistance applicants were made available to intervention and control patients. Using pharmacy dispense records, the authors measured medication possession ratio (MPR) at 90 days (primary outcome) and proportion of days covered (PDC) at 90 days and MPR and PDC at 180 and 365 days (secondary outcomes). Of the 561 patients randomized, only 427 had sufficient records to analyze. Adherence was high with only 41 patients having MPR less than 80% at 90 days. There was no difference in adherence between intervention and control patients for primary outcome (odds ratio 0.94)) or secondary outcomes. The authors felt that given the already high levels of adherence in both study groups, reassessing the DOAC checklist outside of a traditional trial may be more fruitful.

Adherence patterns to oral hypoglycemic agents among primary care patients with type 2 diabetes.
This study’s objective was to examine patterns of adherence to oral hypoglycemic agents among primary care patients with type 2 diabetes mellitus and to assess whether these patterns were associated with baseline intervention allocation, sociodemographic characteristics, and clinical indicators. Adherence patterns for 72 participants were examined by Medication Event Monitoring System (MEMS) caps at baseline and 12 weeks. Participants were randomly allocated to a Patient Prioritized Planning (PPP) intervention or a control group. A card-sort task was used in the PPP intervention to identify health-related priorities that included social determinants of health to address medication nonadherence. Afterward, a problem-solving process was used to address unmet needs involving referral to resources. Patients were found to be either adherent, increasingly adherent, or non-adherent. Participants assigned to the PPP intervention were significantly more likely to have a pattern of improving adherence and adherence than participants assigned to the control group.

Association between hospital-physician vertical integration and medication adherence rates.
This study’s goal was to test the association between vertical integration of primary care providers (PCPs) and adherence rates for anti-diabetics, renin angiotensin system antagonists (RASA), and statins. Data was extracted from Medicare Part B outpatient fee-for-service claims and Medicare Part D event data from 2014 to 2017. There was a 23% increase in the proportion of patients who had a vertically integrated PCP during the study period. Changes in adherence did not differ significantly between patients based on whether their PCP became integrated. However, among patients with PCPs who become integrated, there were significant decreases in patients who were above 80 years old, were Black, Asian, Hispanic, or Native America, and had greater comorbidities for all three classes.

Impact of mail-based continuous positive airway pressure initiation on treatment usage and effectiveness.
Traditional care for patients starting continuous positive airway pressure (CPAP) therapy has involved face-to-face visits with a trained professional for hands-on guidance and mask fitting assessment. However, in an effort to increase accessibility, numerous healthcare systems are transitioning to remote CPAP initiation by mailing equipment to patients. Although this method offers potential advantages, the impact on patient outcomes remains uncertain. Specifically, concerns have been raised about the potential decrease in CPAP adherence due to the absence of in-person training. The purpose of this study was to evaluate treatment usage following either in-person or mailed CPAP initiation. In response to the COVID-19 pandemic, the researcher’s medical center transitioned from in-person to mailed CPAP distribution in March 2020. A cohort of newly diagnosed obstructive sleep apnea (OSA) patients who began CPAP therapy in the months preceding (n = 433) and following (n = 186) this shift was form. The researchers then compared 90-day adherence between the two groups. The study found the average nightly PAP usage was moderate in both cohorts. No significant differences were observed in unadjusted or adjusted analyses.

Adjuvant endocrine therapy non-initiation and non-persistence in young women with early-stage breast cancer.
The purpose of this study was to describe oral adjuvant endocrine therapy (ET) non-initiation and non-persistence in young women with breast cancer to inform strategies to improve adherence. The researchers identified 693 women with hormone receptor-positive, stage I to III breast cancer enrolled in a cohort of women diagnosed with breast cancer at 40 years or less, assessed ET decision-making and identified variables related with non-initiation/non-persistence and to assess the relationship between non-persistence and recurrence. The study found that by 18 months, 9% had not initiated ET. Black women had a greater chances and women with a college degree had lower chances of non-initiation. Of the 607 women who initiated, 20% were non-persistent. The researchers specified that younger age, being married or partnered, and indicating greater weight issues were related with higher chances of non-persistence. Having received chemotherapy and higher burdens of hot flashes and vaginal symptoms were related with lower odds of non-persistence. Women who initiated therapy had an increased likelihood of reporting shared decision-making than non-initiators (57% vs. 38%), and women who were non-persistent were less likely to report high confidence with the decision than women who were persistent (40% vs. 63%).

Implementation of an evidence-based intervention with safety net clinics to improve mammography appointment adherence among underserved women.
This study evaluated the implementation of an evidence-based intervention in safety-net clinics to improve mammography appointment adherence in underserved women called the Peace of Mind Program. The intervention was implemented in 19 Federally Qualified Health centers and charity care clinics within the Greater Houston area. Surveys were given prior to adoption and at eight weeks post implementation to assess Consolidated Framework for Implementation Research constructs. A total of 4402 women were surveyed (baseline period 2078, intervention period 2324). Women in the intervention period or who completed the intervention were more likely to attend or reschedule their mammography appointment than those who did not complete the intervention. A total of 15 clinics prior to adoption and eight clinics completed the survey post implementation.

Virtual voices: examining social support exchanged through participant-generated and unmoderated content in a mobile intervention to improve HIV antiretroviral therapy adherence among GBMSM.
The goal of this study was to investigate how social support was provided and sought by gay, bisexual, and other men who have sex with men (GBMSM) within a technology-based antiretroviral therapy (ART) adherence intervention. Participants used the messaging feature in to discuss and exchange support around HIV treatment and care. The most salient HIV treatment and care issues were lab results, upcoming tests, ART adherence and side effects, regimen changes, and relationships with healthcare providers. The authors concluded that this analysis provided an opportunity to understand how participants informally interact with one another, how they seek and provide social support online, and their relevant personal issues.
