Respiratory syncytial virus (RSV) is associated with considerable morbidity and mortality among older adults (aged ≥60 years) and adults with certain chronic conditions in the United States (US). ...Despite this burden, no previous studies have assessed the knowledge, attitudes, and perceptions (KAP) of RSV among these populations. This study evaluates RSV-related KAP among US adults at increased risk of severe RSV infection. A cross-sectional, web-based survey was administered from May to June 2022 to better understand respiratory infection- and RSV-related KAP among US adults who are at risk of severe RSV infection. The survey included ≥200 adults in each of 4 subgroups: adults aged 60-89 years, and adults aged 18-59 years with ≥1 chronic cardiovascular condition, chronic pulmonary condition, or diabetes mellitus. Survey responses were analyzed descriptively overall and by subgroup, with exploratory logistic regression modeling used to evaluate characteristics associated with RSV awareness and concern. Among the 827 survey respondents, only 43.3% had ever heard of RSV (
= 358/827). The study identified key knowledge gaps (e.g. bacterial vs. viral nature of respiratory infections, RSV seasonality, common RSV symptoms, extent to which RSV causes respiratory infections in specific patient populations). Although 33.7% of RSV-aware adults (
= 120/356) reported being worried/very worried about RSV, 67.3% (
= 241/358) rarely consider RSV as a potential cause of their cold/flu-like symptoms. Results from this study highlight important knowledge gaps related to RSV, perceived risk, and severity of RSV. Findings can be used to support the development of tailored education efforts to support RSV prevention.
Abstract Purpose Although the efficacy of canagliflozin has been well established in clinical trials, research regarding its use and impact on outcomes in clinical practice has been limited by the ...availability of data on observations up to and beyond 6 months after the initial use of canagliflozin. The purpose of this study was to evaluate changes in glycemic control after the initiation of canagliflozin use in a managed care population. Methods A retrospective cohort analysis in adults with type 2 diabetes mellitus was conducted using medical and pharmacy claims data and laboratory results from the Humana Research Database. The differences between hemoglobin (Hb) A1c levels pre- and postindex were assessed. Changes from pre- to postindex in the percentages of patients achieving glycemic control (eg, HbA1c <7% or <8%) were evaluated. HbA1c levels were also observed during days 31 to 90, 91 to 180, 181 to 270, and 271 to 360 postindex relative to preindex to assess the durability of HbA1c change over time. Analyses were conducted in the full cohort and in 3 subgroups: (1) HbA1c ≥7% at baseline; (2) age ≥65 years; (3) and Medicare members age ≥65 years and HbA1c ≥7% at baseline. Findings Among the 1562 patients meeting the study criteria, the mean HbA1c values pre- and postindex were 8.6% and 7.9%, respectively ( P < 0.0001); in the subgroup with HbA1c ≥7% at baseline, these values were 8.9% and 8.0%; in the subgroup aged ≥65 years, 8.5% and 7.9%; and in the subgroup aged ≥65 years with HbA1c ≥7% at baseline, 8.8% and 8.1% (all subgroups, P < 0.001). The percentages of patients meeting glycemic-control thresholds (HbA1c <7%, <8%) were significantly greater at postindex in the full study cohort and in all 3 subgroups (all, P < 0.001). Based on longitudinal HbA1c results in the postindex periods, HbA1c reduction appeared durable across 12 months. Implications The findings from this study suggest that treatment with canagliflozin is associated with improved glycemic control, as evidenced by HbA1c reduction and glycemic goal attainment. Even though not all patients had valid HbA1c measurements available in each quarter during the follow-up period, the reductions in mean HbA1c appeared durable across the postindex intervals. The observations from this majority Medicare Advantage with Prescription Drug sample and, more specifically, in the subgroups limited to patients aged ≥65 years are particularly informative for payers and providers managing or caring for patients of this age with diabetes.
BACKGROUND:
Patients with rheumatoid arthritis, psoriasis, psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, or ulcerative colitis may require treatment with a biologic or targeted ...synthetic disease-modifying antirheumatic drug (b/tsDMARD). Often, a tumor necrosis factor inhibitor (TNFi) is the initial b/tsDMARD. The TNFi may not be effective or may not be well tolerated, so patients will opt for a different TNFi or switch to a non-TNFi b/tsDMARD. No preference for a TNFi or non-TNFi has been established and guidelines are unclear.
OBJECTIVE:
To evaluate effectiveness by comparing patients using a second TNFi vs a non-TNFi after initial use of TNFi based on treatment patterns and health care utilization.
METHODS:
This retrospective analysis used Medicare Advantage prescription drug (MAPD) plan, Medicaid, and commercial plan claims data from Humana’s Research Database (Louisville, KY). The first claim for TNFi or non-TNFi (July 1, 2016, to June 30, 2018) following earlier TNFi was the index date. Patients were required to have pre-index enrollment of 6 months and 12 months post-index along with diagnosis of rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis, or psoriasis. During the 12-month follow-up, persistence to the index TNFi or non-TNFi was measured as continued therapy without a gap exceeding 45 days (81 days for intravenous infusions). Adherence was proportion of days covered at least 0.8. Addition of a nonbiologic DMARD or corticosteroid was also identified. Inpatient admissions and emergency department visits were observed. Inverse probability of treatment weights was used to balance cohorts. Logistic regression models were fit to TNFi vs non-TNFI on treatment and utilization measures.
RESULTS:
Of identified patients, 1,022 were indexed to a second TNFi and 1,024 were indexed to non-TNFi. Weighted cohorts were balanced, with mean age 56.5 vs 56.4 years, 70.5% vs 70.7% female sex, and 68.0% vs 67.9% MAPD plan. No differences were observed on persistence or adherence, with adjusted odds ratios (OR) of 1.05 (95% CI = 0.91-1.20) and 1.04 (0.91-1.20), respectively. No differences were observed for changes in therapy via switching to another TNFi/non-TNFi (OR = 0.93; 95% CI = 0.54-1.62), via nonbiologic DMARD addition (OR = 0.95; 95% CI = 0.83-1.11), or corticosteroid addition (OR = 1.09; 95% CI = 0.92-1.88). No differences were observed for hospitalization (OR = 1.16; 95% CI = 0.99-1.37) or emergency department visits (OR = 1.02; 95% CI = 0.89-1.18).
CONCLUSIONS:
No differences were found between a second TNFi vs a non-TNFi. As a result, choice of TNFi or non-TNFi following an initial TNFi may be driven by relevant patient-specific considerations. At the population level, policies that prefer either TNFi or non-TNFi appear reasonable.

We researched whether a second tumor necrosis factor inhibitor (TNFi) or non-TNFi was a more effective treatment. The data source was health care claims from 2016 to 2019. We identified 1,022 TNFi and 1,024 non-TNFi patients. We balanced study cohorts using statistical weighting. Patients were measured for 1 year. We found no differences in treatment patterns or health care utilization. These results suggest that neither TNFi nor non-TNFi is more effective after an initial TNFi. This suggests that either therapy could be reasonably preferred.
Our real-world findings demonstrate that among patients with chronic inflammatory conditions using a second-line TNFi or non-TNFi agent following a first-line TNFi, there were no differences in medication treatment patterns or health care utilization measures. With no differences in effectiveness of second-line TNFi or non-TNFi therapies expected at the population level, managed care policies could prefer either option but should allow for patient-specific considerations.
Medication therapy management (MTM) programs are designed to improve clinical outcomes and enhance appropriate medication use. Comprehensive medication reviews (CMRs) and targeted medication reviews ...(TMRs) are 2 broad interventions defined within MTM services. While MTM services have been extensively researched, there are few comparisons of CMR versus non-CMR interventions. Given the variability in MTM interventions and lack of a consistent TMR definition in the literature, this study sought to compare CMRs and TMRs that were clearly defined based on Centers for Medicare & Medicaid Services (CMS) criteria.
To (a) compare acute inpatient admissions and emergency department (ED) visits between patients participating in MTM services (CMR, TMR, or both) and eligible nonparticipating patients and (b) examine the effect of receiving TMR services on medication adherence.
This was a retrospective cohort study of patients with Medicare Part D coverage who received MTM services and a 1:1 propensity score-matched control group. Participants had to be eligible for MTM services in 2014 or 2015 based on CMS requirements. CMRs were offered to all MTM-eligible patients, while TMRs were completed based on clinical rules that helped identify medication-related problems (MRPs). The date of MTM intervention, or eligibility for the control group, was considered the index date. Participants had to be continuously enrolled in a Medicare Advantage plan that included prescription drug coverage during the study period and have at least 6 months of data before and after the index date. Medical and pharmacy claims were assessed to examine trend-adjusted inpatient admissions and ED visits from pre-index to post-index date for participants and matched controls.
In 2014 and 2015, receipt of TMR interventions was associated with statistically significant reductions in acute inpatient admissions. In 2014, there were 55.2 fewer admits per 1,000 individuals (95% CI = 29-81) and 30.8 fewer admits per 1,000 individuals in 2015 (95% CI = 20-42). Receipt of CMR-only interventions was associated with fewer acute inpatient admissions only when coupled with preidentification of MRPs (36.8 95% CI = 25-49 fewer admits per 1,000 individuals). In 2015, there were significant reductions in ED visits for participants receiving TMR-only interventions or TMR/CMR interventions (26.1 95% CI = 11-41 and 12.0 95% CI = 1-23 fewer ED visits per 1,000 individuals, respectively). In both years, a larger percentage (0.4% for oral diabetes medications; 7.7% for antihypertensives; 3.0% for statins) of MTM participants had greater improvements in medication adherence in the post-index period compared with controls.
Receiving MTM services targeted at resolution of MRPs (TMR or CMR/TMR) resulted in positive reductions in health care utilization and increases in medication adherence. Given the importance of optimal medication utilization, this study highlights the need for additional focus on resolution of MRPs through TMRs and CMRs that can support improved clinical outcomes.

This retrospective cohort study compared sodium-glucose co-transporter-2 (SGLT2) inhibitor and glucagon-like peptide-1 (GLP-1) agonist therapeutic drug classes on cardiovascular (CV) outcomes, ...treatment persistence/discontinuation, healthcare utilization and costs. Using medical and pharmacy claims data from the Humana Research Database, new users of SGLT2 inhibitors or GLP-1 agonists from January 2015 to June 2017 were identified. Eligible patients were 19-89 years, enrolled in a Medicare Advantage Prescription Drug or fully-insured commercial health plan, with at least 12 months of continuous enrollment pre- and post-index date (i.e., date of first new prescription). Propensity score matching (1:1) was used to balance baseline characteristics. Cox proportional hazards models were used to compare CV outcomes and treatment discontinuation. Healthcare resource utilization and costs were compared using Wilcoxon signed rank test. A total of 5,507 patients were included in each treatment group. Patients indexed to use GLP-1 agonists were more likely to discontinue treatment (hazard ratio 1.15, 95% confidence interval 1.10-1.21) and more likely to encounter an inpatient hospitalization (14.4% vs. 11.9%, P<0.001) or emergency department visit (27.4% vs. 23.5%, P <0.001) compared to patients indexed on SGLT2 inhibitors. The risk of primary composite CV outcome (myocardial infarction or stroke or mortality) and secondary CV outcome (heart failure or death) was similar across cohorts. The average per-person per-month total cost ($1,796 vs. $1,617, P<0.001), medical ($904 vs. $834, P<0.001) and pharmacy costs ($891 vs. $783, P<0.001) were higher for the GLP-1 agonist cohort compared to the SGLT2 inhibitor cohort. Although differences in extra-glycemic CV benefits were not established, these findings may be useful to providers and payers, as this real-world data showed SGLT2 inhibitors were associated with longer treatment persistence and reduced healthcare utilization and costs relative to GLP-1 agonists.

While emerging evidence shows cardiovascular (CV) benefits associated with use of specific glucagon-like peptide-1 (GLP-1) agonists, there is limited data on how outcomes compare between agents in ...the same drug class. This retrospective cohort study compared once-weekly dulaglutide and once-daily liraglutide on CV outcomes, treatment persistence/discontinuation, healthcare utilization and costs. Using administrative claims data from a large commercial and Medicare Advantage Prescription Drug health plan, new users of liraglutide or dulaglutide from January 2015 to June 2017 were identified. Eligible patients were 19-89 years, with at least 12 months of continuous enrollment pre- and post-index date (i.e., date of first new prescription). Patients who had prescription claims for other GLP-1 agonists were excluded. Propensity score matching (1:1) resulted in 2,245 patients in each treatment arm. The risk of primary composite CV outcome (myocardial infarction MI or stroke or mortality) and secondary CV outcome (heart failure HF or mortality) was similar across treatment groups, but patients indexed to dulaglutide were less likely to encounter a MI (relative risk RR 0.80, P=0.028) or HF (RR 0.81, P=0.001) event. Treatment discontinuation was lower in patients who used dulaglutide vs. liraglutide (57.8% vs. 63.2%, P<0.0001; hazard ratio 0.85, 95% confidence interval 0.79-0.92). The average per-person per-month pharmacy cost was higher for dulaglutide compared to the liraglutide cohort ($1,027 vs. 954, P=0.047). Total and medical costs, inpatient hospitalization stays, emergency department visits and outpatient service visits were similar across cohorts. Despite a lack of significant effect on the study’s composite CV outcomes, this real-world study showed longer treatment persistence with the use of dulaglutide that may be associated with lower MI and HF events. Findings may be useful to providers, especially in the treatment of patients who prefer once-weekly versus once-daily subcutaneous injection.

Since 2016, empagliflozin (EFZ) has been known to reduce cardiovascular (CV) events in patients with type 2 diabetes; however, similar label expansions for dapagliflozin (DFZ) and canagliflozin (CFZ) ...are quite recent. To date, limited evidence has been published comparing these drugs in real-world practice. This retrospective cohort study address that gap, and used administrative claims data from a nationwide Medicare Advantage Prescription Drug and commercial health plan to compare CFZ, EFZ and DFZ on CV outcomes, treatment persistence, healthcare utilization and costs. Eligible patients naïve to the SGLT2 inhibitor drug class for 6 months from January 2015 to June 2017 were identified. Patients had at least 12 months of continuous enrollment pre- and post-index date (i.e., date of first new prescription). Propensity score method using inverse probability of treatment weighting was used to adjust outcomes. A total of 5,503, 2,052 and 587 patients used CFZ, EFZ and DFZ, respectively. Weighted comparisons showed no difference in the risk of primary composite CV outcome (myocardial infarction, stroke, or mortality) between treatments, but a lower risk of secondary CV outcome (heart failure or death) in the DFZ cohort (hazard ratio 0.82, 95% CI 0.75-0.88) compared to CFZ. Patients indexed to use EFZ were more likely to remain persistent to treatment (odds ratio OR 1.09, 95% CI 1.03-1.16), and patients who used DFZ had lower odds of an emergency department visit encounter (OR 0.85, 95% CI 0.79-0.92), relative to the use of CFZ. There were no differences in inpatient hospitalization stays and outpatient services between treatment groups. This population-based study showed minor differences in clinical and cost outcomes between CFZ, EFZ and DFZ, including a post-hoc analysis showing slight variations in use of adjuvant glucose lowering therapies across the SGLT2 inhibitor cohorts. With the ever-evolving landscape of treatment in the care of patients with diabetes, these findings may be helpful to providers.

To compare SGLT2 inhibitors and GLP-1 agonists on cardiovascular (CV) outcomes, treatment persistence/discontinuation, healthcare utilization and costs.
This retrospective cohort study utilized ...medical and pharmacy claims to identify new SGLT2 inhibitor or GLP-1 agonist users from January 2015 to June 2017. A total of 5,507 patients were included in each treatment group after 1:1 propensity score matching. Cox proportional hazards models were used to compare CV outcomes and treatment discontinuation. Healthcare utilization and costs were compared using Wilcoxon signed rank test.
No differences in the primary composite CV outcome or secondary CV outcome were observed. Patients using GLP-1 agonists were more likely to discontinue treatment (hazard ratio 1.15, 95% confidence interval 1.10–1.21) and more likely to have an inpatient hospitalization (14.4% vs. 11.9%, P < 0.001) or emergency department visit (27.4% vs. 23.5%, P < 0.001) compared to patients on SGLT2 inhibitors. The average per-person per-month cost difference was +$179 for total cost (P < 0.001), +$70 for medical cost (P < 0.001) and +$108 for pharmacy cost (P < 0.001) for GLP-1 agonists compared to SGLT2 inhibitors.
Differences in composite CV outcomes were not established. However, other findings that favored SGLT2 inhibitors should be weighed against the known risks associated with this therapeutic class.
Adherence to oral antihyperglycemic agents (AHAs) is important for managing blood glucose levels and avoiding hospitalizations or diabetes complications. Previous studies have found that use of ...mail-order pharmacy dispensing channels results in greater adherence than use of community pharmacies, but the link between use of mail-order pharmacies and improved clinical outcomes has not been established.
To compare the effect of mail-order and community pharmacy use on adherence to oral AHAs, hemoglobin A1c (A1c) level, and glycemic control, as well as emergency department (ED) and inpatient hospital use.
This retrospective cohort study of administrative claims data from January 1, 2008, to December 31, 2016, included patients with Medicare Advantage Prescription Drug plan coverage with ≥ 2 claims for the same oral AHA and a diagnosis of type 2 diabetes mellitus (T2DM). Patients were indexed to the start of the most advanced oral AHA identified to begin study observations at the start of a new treatment and assigned to mail-order or community pharmacy cohorts based on which channel dispensed ≥ 80% of their oral AHA claims; all others were excluded. Mail-order and community pharmacy patients were 1:1 propensity score matched. Matched cohorts were compared on proportion of days covered (PDC), adherence (PDC ≥ 0.8), A1c level, glycemic control, and ED and inpatient use for measurement periods of 12, 24, 36, and 48 months post-index.
19,307 mail-order and 19,307 community pharmacy users were matched. PDC was higher for mail-order pharmacy users at 12 months (0.93 vs. 0.82, P < 0.001) and sustainable through 48 months (0.87 vs. 0.77, P < 0.001). Adherence was also greater for mail-order pharmacy patients through 12 months (86% vs. 68%, P < 0.001) and sustainable through 48 months (78% vs. 62%, P < 0.001). Glycemic control as A1c < 7% was not significantly different, but control as A1c < 8% was greater for mail-order pharmacy users at 12 months (91% vs. 89%, P = 0.006) and was greater through 36 months (93% vs. 89%, P = 0.043). Effects on A1c level were not evident. Mail-order pharmacy users were less likely to have an ED visit within 12 months (26% vs. 28%, P < 0.0001), and the difference was observed through 36 months (50% vs. 54%, P < 0.0001). Similarly, fewer mail-order pharmacy users had an inpatient hospitalization within 12 months (17% vs. 19%, P < 0.0001), and the difference was observed through 48 months (43% vs. 47%, P = 0.009).
The results of the study demonstrate a benefit to patients who use mail-order pharmacies for chronic medications to treat T2DM. The study identified greater glycemic control, lower ED use, and lower hospitalization among individuals using mail-order pharmacies. These positive outcomes were evident in the near term and sustained over time.
This study received no outside funding but was sponsored by Humana through regular employment activities by Schwab, Racsa, and Worley, who are employed by Humana Healthcare Research (formerly Comprehensive Health Insights). This study found benefits related to using mail-order versus community pharmacies for dispensing antihyperglycemic agents in the treatment of type 2 diabetes.

Medication nonadherence diminishes the benefits of preexposure prophylaxis (PrEP) for the 1.2 million Americans at risk for HIV exposure.
To describe HIV PrEP treatment patterns among Medicare ...Advantage Prescription Drug (MAPD) plan and commercially insured beneficiaries.
This retrospective cohort study identified patients aged 16 to 89 years with at least 1 dispensing of emtricitabine-tenofovir disoproxil fumarate from July 2012, through December 2020, or emtricitabine-tenofovir alafenamide from October 2019 through December 2020, and who were continuously enrolled at least 12 months prior to and following the earliest PrEP claim. Outcomes were HIV PrEP adherence measured by proportion of days covered (PDC) using 2 binary thresholds of 0.60 (4 doses/week) and 0.80 (5-6 doses/week) and duration of index treatment episode, total time on treatment, and total number of prescription fills.
The study cohort of 707 (292 MAPD plan, 415 commercial) was predominantly made up of male patients (90.0%) and resided in the South (78.9%) with a mean age of 46.2 years (MAPD plan: 54.5, commercial: 40.4). Both populations engaged in high-risk sexual behavior (All: 18.7%, MAPD plan: 16.8%, commercial: 20.0%) and experienced sexually transmitted infections (All: 3.3%, MAPD plan: 2.1%, commercial: 4.1%). The mean index treatment episode length was 297.0 days (MAPD plan: 283.6, commercial: 306.5). Total time on treatment was 477.3 days (MAPD plan: 450.7, commercial 496.0). At 3 months, 84.9% (MAPD plan: 83.6%, commercial: 85.8%) and at 12 months, 58.7% (MAPD plan: 57.2, commercial: 59.8) of patients achieved a PDC of at least 0.80. At 3 months, 100.0% (MAPD plan: 100.0%, commercial: 100.0%), and at 12 months, 74.3% (MAPD plan: 70.2%, commercial: 76.9%) of patients achieved a PDC of at least 0.60. The cohort had a mean of 16.4 fills of 30 days (MAPD plan: 16.4, commercial: 16.3) supply.
There is an opportunity for clinical programs to focus on improving longer-term PrEP adherence among individuals at risk for HIV exposure.
