Real-World Effectiveness of Mepolizumab in Patients with Allergic and Non-Allergic Asthma.

Purpose: Real-world data on mepolizumab in patients with severe asthma and allergic and non-allergic phenotypes are limited. This study investigated the effectiveness of mepolizumab treatment in patients with severe asthma with allergic and non-allergic phenotypes. Patients and Methods: This retrospective cohort study (GSK ID: 214148) used administrative claims data from the Optum Research Database. Eligible patients were ≥6 years of age with asthma and had ≥2 mepolizumab claims post-index. Index date was the first mepolizumab claim/administration (January 2016-December 2018). Patients were divided into two cohorts: allergic and non-allergic asthma, based on diagnosis codes, medication use and lab test results. Outcomes included the rate of asthma-related exacerbations and oral corticosteroid (OCS) use during the 12 months before (baseline period) and 12 months after (follow-up period) mepolizumab initiation. Study ended in December 2019. Results: Overall, 240 (44.6%) and 298 (55.4%) patients were included in the allergic and non-allergic asthma cohorts, respectively. Mean (standard deviation [SD]) counts of asthma-related exacerbations were significantly reduced from baseline to follow-up in both the allergic and non-allergic asthma cohorts (3.2 [2.5] to 2.1 [2.1], p < 0.001 and 2.5 [2.2] to 1.7 [1.9], p < 0.001, respectively). The mean number of OCS pharmacy claims was significantly decreased by 33.3% and 41.4% from baseline to follow-up in the allergic and non-allergic cohorts, respectively (p < 0.001); mean daily OCS dose significantly decreased by 30.6% and 45.4%, respectively (p < 0.001) as well as the mean number of OCS bursts, which decreased by 44.9% and 41.8%, respectively (p < 0.001). No significant differences were observed between cohorts in reductions in asthma exacerbations, counts of OCS pharmacy claims or OCS bursts (baseline to follow-up). Conclusion: Mepolizumab significantly reduced asthma exacerbations and OCS use in patients with allergic and non-allergic asthma, suggesting that mepolizumab provides real-world benefit in severe asthma irrespective of whether a patient has an allergic phenotype.

Real-world association between systemic corticosteroid exposure and complications in US patients with severe asthma.

BACKGROUND: Systemic corticosteroid (SCS) use remains widespread among patients with severe asthma, despite associated complications. OBJECTIVE: Evaluate the association between cumulative SCS exposure and SCS-related complications in severe asthma. METHODS: This retrospective, longitudinal study used claims data from the Optum Clinformatics Data Mart database (GSK ID: 214469). Eligible patients (≥ 12 years old) had an asthma diagnosis and were divided into two cohorts: SCS use and non/burst-SCS use. Patients in the SCS use cohort had a claim for a daily prednisone-equivalent dose ≥ 5 mg SCS following ≥ 6 months of continuous SCS use; those in the non/burst-SCS cohort had no evidence of continuous SCS use and had a non-SCS controller/rescue medication initiation claim. For each cohort, the date of the qualifying claim was the index date. SCS users were further stratified by SCS use during each quarter of follow-up: low (≤ 6 mg/day), medium (> 6-12 mg/day), high (> 12 mg/day), and continuous high (≥ 20 mg/day for 90 days). SCS-related complications were evaluated in the quarter following SCS exposure. The adjusted odds ratios (OR) of experiencing SCS-related complications during follow-up in each of the SCS use groups versus the non/burst SCS cohort were calculated using generalized estimating equations models. RESULTS: SCS and non/burst-SCS use cohorts included 7473 and 89,281 patients (mean follow-up: 24.6 and 24.2 months), respectively. Compared with the non/burst-SCS use cohort, medium, high, and continuous high SCS use was associated with greater odds of any SCS-related complication (adjusted OR [95% confidence interval]: 1.30 [1.21, 1.39], 1.49 [1.35, 1.64] and 1.63 [1.40, 1.89], respectively) including increased acute gastrointestinal, cardiovascular, and immune system-related complications, and chronic cardiovascular, metabolic/endocrine, central nervous system, bone-/muscle-related, ophthalmologic, and hematologic/oncologic complications. Low-dose SCS use was also associated with significantly increased odds of acute gastrointestinal and immune system-related complications, and chronic bone-/muscle-related and hematologic/oncologic complications versus the non/burst-SCS use cohort. CONCLUSION: SCS use, even at low doses, is associated with increased risk of SCS-related complications among patients with severe asthma.

Real-world effectiveness of mepolizumab in severe asthma and chronic rhinosinusitis in the United States: Impact of comorbidity and sinus surgery.

BACKGROUND: Trial data demonstrate that mepolizumab, a humanized anti-interleukin 5 monoclonal antibody, is effective for patients with severe asthma and comorbid chronic rhinosinusitis (CRS) with nasal polyps. This real-world, retrospective cohort study investigated mepolizumab for US patients with severe asthma and CRS with/without sinus surgery. METHODS: IQVIA PharMetrics Plus claims data from baseline and follow-up (12 months before and after mepolizumab initiation) were used to analyze three patient cohorts: cohort 1 (severe asthma only); cohort 2 (severe asthma + comorbid CRS without sinus surgery); and cohort 3 (severe asthma+comorbid CRS+sinus surgery), allowing for cross-cohort comparisons. RESULTS: The analysis included 495, 370, and 85 patients in cohort 1, cohort 2, and cohort 3, respectively. Systemic and oral corticosteroid use was lower for all cohorts after mepolizumab initiation. In cohort 3, asthma rescue inhaler and antibiotic use were lower during follow-up than baseline. Asthma exacerbations were reduced by 28% to 44% comparing follow-up versus baseline, with the largest reduction in cohort 3 (ratio of incidence rate ratio [RR] vs cohort 1: 0.76; p = 0.036). Reductions in oral corticosteroid claims were greater following mepolizumab initiation for cohort 3 versus cohort 1 (RR, 0.72; p = 0.011) and cohort 2 (RR, 0.70; p < 0.01). In cohorts 1 through 3, outpatient and emergency department visits were reduced by 1 to 2 and 0.4 to 0.6 visits annually, asthma-related and asthma exacerbation-related total costs were reduced by $387 to $2580 USD, and medical costs were reduced by $383 to $2438 USD during follow-up. CONCLUSIONS: Consistent with trial data, mepolizumab use in real-world practice shows benefits across comorbid patient cohorts with more a pronounced impact in those with severe asthma+comorbid CRS + sinus surgery.

Biologic use and treatment patterns in patients with chronic rhinosinusitis with nasal polyps: a US real-world study.

BACKGROUND: Several biologics are now approved in the US as add-on treatments for chronic rhinosinusitus with nasal polyps (CRSwNP). This cross-sectional, retrospective, real-world study aimed to characterize treatment patterns and identify predictors of biologic use among patients with CRSwNP. METHODS: Adults in the Merative MarketScan Commercial and Medicare Supplemental Databases with medical claims for CRSwNP were identified June 2018-June 2019 (identification period [IP]). Patient characteristics were collated in the IP and treatment pattern data during the IP plus the following year (July 2019-June 2020; observation period [OP]). Data were stratified by sinus surgery and biologic use. RESULTS: Of the 5997 eligible patients identified (58% male, mean age 48.1 years), 10.7% (n = 642) used biologics during the OP. More biologic users had common respiratory conditions than non-users, particularly asthma (89.1% vs 35.0%; P < 0.001). Biologic users had fewer diagnostic services but more drug-related services than non-users. Only 11.6% of patients who had sinus surgery used biologics, with most (56.1%) having their first biologic dose before sinus surgery and 12.5% ≤ 30 days after. Oral corticosteroid (OCS) use was higher in biologic users than non-users (all patients: 68.8% vs 42.5%; P < 0.001) and in those with/without sinus surgery. Comorbidities, prior OCS/doxycycline use, and age (< 65 years) increased the odds of biologic use, with asthma increasing the odds 5.46 times (P < 0.001). CONCLUSIONS: Biologic use was more common before first/next sinus surgery and in patients with high unmet need, elucidating predictors of biologic use that could be used in clinical practice.

Characteristics and Disease Burden of Patients With Eosinophilic Granulomatosis With Polyangiitis Initiating Mepolizumab in the United States.

BACKGROUND/OBJECTIVE: Although the high disease burden associated with eosinophilic granulomatosis with polyangiitis (EGPA) has been established, the disease burden in patients initiating mepolizumab in real-world practice is poorly understood. This study aimed to assess characteristics and burden of real-world patients with EGPA initiating mepolizumab. METHODS: This was a database study (GSK study ID: 214156) of US patients (≥12 years old) with EGPA and ≥1 mepolizumab claim (index date) identified from the Merative MarketScan Commercial and Medicare Supplemental Databases (November 1, 2015, to March 31, 2020). Outcomes assessed in the 12-month baseline period before index (inclusive) included patient characteristics, treatment use, EGPA relapses, asthma exacerbations, health care resource utilization, and costs. RESULTS: In the 103 patients included (mean age, 51.1 years; 63.1% female), the most common manifestations were asthma (89.3%), chronic sinusitis (57.3%), and allergic rhinitis (43.7%). In total, 91.3% of patients had ≥1 oral corticosteroid (OCS) claim (median dose, 7.4 mg/d prednisone-equivalent), 45.6% were chronic OCS users (≥10 mg/d during the 90 days preindex), 99.0% had ≥1 EGPA-related relapse, and 62.1% ≥1 asthma exacerbation. During the baseline period, 26.2% and 97.1% of patients had EGPA-related inpatient admissions and office visits, respectively. Median all-cause total health care costs per patient were $33,298, with total outpatient costs ($16,452) representing the largest driver. CONCLUSIONS: Before initiating mepolizumab, a substantial real-world EGPA disease burden is evident for patients, with resulting impact on health care systems, and indicative of unmet medical needs. Mepolizumab treatment, with a demonstrated positive clinical benefit-risk profile may represent a useful treatment option for reducing EGPA disease burden.

Clinical and economic burden of pneumococcal disease among individuals aged 16 years and older in Germany.

This study assessed the incidence rate of all-cause pneumonia (ACP) and invasive pneumococcal disease (IPD) and associated medical costs among individuals aged ≥16 in the German InGef database from 2016 to 2019. Incidence rate was expressed as the number of episodes per 100 000 person-years (PY). Healthcare resource utilisation was investigated by age group and by risk group (healthy, at-risk, high-risk). Direct medical costs per ACP/IPD episode were estimated as the total costs of all inpatient and outpatient visits. The overall incidence rate of ACP was 1345 (95% CI 1339-1352) and 8.25 (95% CI 7.76-8.77) per 100 000 PY for IPD. For both ACP and IPD, incidence rates increased with age and were higher in the high-risk and at-risk groups, in comparison to the healthy group. ACP inpatient admission rate increased with age but remained steady across age-groups for IPD. The mean direct medical costs per episode were €8075 (95% CI 7121-9028) for IPD and €1454 (95% CI 1426-1482) for ACP. The aggregate direct medical costs for IPD and ACP episodes were estimated to be €8.5 million and €248.9 million respectively. The clinical and economic burden of IPD and ACP among German adults is substantial regardless of age.

Pneumococcal vaccination coverage in individuals (16-59 years) with a newly diagnosed risk condition in Germany.

BACKGROUND: Despite recommendations from the German Standing Committee on Vaccination (STIKO), pneumococcal vaccination coverage remains low in vulnerable populations. This study estimated the pneumococcal vaccination coverage rate (VCR) and timing among individuals aged 16-59 years in Germany who were recommended to receive pneumococcal vaccination, according to STIKO. METHODS: A retrospective cohort analysis was conducted using the German InGef database. Individuals aged 16 to 59 years diagnosed with at least one "at-risk" (chronic disease) or "high-risk" (e.g., immunocompromising) condition considered to be at-risk of pneumococcal infection were identified at the time of first diagnosis, between January 1, 2016 and December 31, 2018, and followed up until December 31, 2019. The percentage of cumulative pneumococcal VCR with 95% confidence interval (CI) was reported for each calendar year of follow-up. RESULTS: There were 334,292 individuals followed for a median of 2.38 (interquartile range (IQR) 1.63-3.13) person years. For individuals aged 16-59 years diagnosed with an incident risk condition in 2016, pneumococcal VCR increased from 0.44% (95% CI 0.41-0.48) in 2016 to 1.24% (95% CI 1.18-1.30) in 2019. In 2019, VCRs were higher in individuals with high-risk conditions compared with at-risk conditions (2.24% (95% CI 2.09-2.40) vs. 0.90% (95% CI 0.85-0.96)). In 2019, VCRs were higher in individuals aged 50 to 59 years compared with individuals aged 16 to 49 years (2.25% (95% CI 2.10-2.41) vs. 0.90% (95% CI 0.84-0.96)). Similar trends were observed in individuals with newly diagnosed risk conditions identified in 2017 and in 2018. Older age, influenza vaccination and increasing number of risk conditions increased the likelihood of pneumococcal vaccination. Median time to vaccination from diagnosis of the risk condition was shorter for high-risk conditions (369.5 days (IQR 155.8-702.0)) compared to at-risk conditions (435.5 days (IQR 196.3-758.8)). CONCLUSION: Despite recommendations from STIKO, pneumococcal vaccination coverage remains very low and with long delays in vulnerable individuals aged 16-59 in Germany. Further efforts are required to increase immunization levels and shorten time to vaccination among individuals 16-59 years of age developing conditions with higher susceptibility to pneumococcal infection.

Cost-effectiveness of the 15-valent pneumococcal conjugate vaccine for high-risk adults in Switzerland.

BACKGROUND: Vaccination against pneumococcal disease (PD) has shown a favorable cost-effectivenessprofile for many national immunization programs. While vaccination efforts have concentrated on children, many adults with underlying illnesses face elevated risks of PD and death. A 15-valent pneumococcal conjugate vaccine (V114) is currently available offering protection against 15 different serotypes and can be used in adults. RESEARCH DESIGN AND METHODS: We examined the cost-effectiveness of V114 vaccination in high-risk adults, aged 18+, in Switzerland. To this end, a Markov model was constructed estimating the lifetime direct medical costs and clinical effectiveness of V114 vaccination on invasive pneumococcal disease (IPD) and non-bacteremic pneumococcal pneumonia (NBPP). RESULTS: Considering 60% vaccine uptake and direct effects of vaccination, in total 760 IPD and 4,396 NBPP in- and outpatient cases could be prevented. Vaccinating high-risk adults with V114 led to CHF 37.4 million additional vaccination costs but saved CHF 14.4 million of medical treatment costs. V114 vaccination produced a gain of 2,095 QALYs and 6,320 LYs compared with no vaccination, leading to incremental cost-effectiveness ratios of CHF 17,866/QALY and CHF 15,616/QALY gained from a health care payer and societal perspective, respectively. CONCLUSIONS: This evidence justifies the implementation of V114 vaccination among high-risk adults in Switzerland.

Estimates of the Health and Economic Burden of Pneumococcal Infections Attributable to the 15-Valent Pneumococcal Conjugate Vaccine Serotypes in the USA.

INTRODUCTION: Despite the availability of vaccines, pneumococcal disease (PD) is associated with high clinical and economic burden, mainly caused by non-vaccine serotypes and certain vaccine-type serotypes. V114 is a 15-valent pneumococcal conjugate vaccine (PCV) that contains two epidemiologically important serotypes, 22F and 33F, in addition to the 13 serotypes in 13-valent PCV (PCV13). This study quantified the epidemiologic and economic burden of PD attributable to V114 serotypes among adults in the USA. METHODS: A Markov model was used to estimate the burden of V114 serotypes in a hypothetical, non-vaccinated cohort of US adults ≥ 19 years of age who were tracked from 2019 until death. The model calculated all the invasive pneumococcal disease (IPD) and non-bacteremic pneumococcal pneumonia (NBPP) cases, deaths, and costs. Economic burden was estimated from a healthcare payer perspective (2019 US dollars) and discounted at 3%. RESULTS: The model estimated 415,229 and 10.3 million lifetime cases of V114-type IPD and NBPP, respectively. Serotypes 22F and 33F caused approximately 33% of IPD cases and 20% of NBPP cases, while serotype 3 accounted for approximately 36% of IPD cases and 13% of NBPP cases. V114 serotypes caused 472,063 total lifetime deaths. Total discounted lifetime costs attributable to V114 serotypes were $44.8 billion US dollars. CONCLUSIONS: In this hypothetical model of a non-vaccinated cohort of US adults, V114 serotypes were associated with a substantial health and economic burden, the majority of which was attributable to serotypes 3, 22F, and 33F. The addition of V114 to the national vaccination recommendations may help to reduce the epidemiologic and economic burden associated with PD in adults ≥ 19 years of age in the USA by providing increased coverage of these serotypes.

Economic Burden of Pneumococcal Disease in Individuals Aged 15 Years and Older in the Liguria Region of Italy.

Despite the availability of vaccines against Streptococcus pneumoniae, the global incidence and economic cost of pneumococcal disease (PD) among adults is still high. This retrospective cohort analysis estimated the cost of emergency department (ED) visits/hospitalizations associated with non-invasive pneumonia and invasive pneumococcal disease among individuals ≥15 years of age in the Liguria region of Italy during 2012-2018. Data from the Liguria Region Administrative Health Databases and the Ligurian Chronic Condition Data Warehouse were used, including hospital admission date, length of stay, discharge date, outpatient visits, and laboratory/imaging procedures. A ≥30-day gap between two events defined a new episode, and patients with ≥1 ED or inpatient claim for PD were identified. The total mean annual number of hospitalizations for PD was 13,450, costing ~€49 million per year. Pneumonia accounted for the majority of hospitalization costs. The median annual cost of hospitalization for all-cause pneumonia was €38,416,440 (per-capita cost: €26.78) and was €30,353,928 (per-capita cost: €20.88) for pneumococcal and unspecified pneumonia. The total number and associated costs of ED visits/hospitalizations generally increased over the study period. PD still incurs high economic costs in adults in the Liguria region of Italy.

Pneumococcal vaccination coverage among adults aged 19 to 64 years with immuno-compromising conditions, cerebrospinal fluid (CSF) leaks, or cochlear implants in the US.

Background: Adults with immuno-compromising conditions, CSF leaks, or cochlear implants are at increased risk for pneumococcal disease (high-risk patients), yet pneumococcal vaccination rates in the US for this group are low.Methods: A retrospective cohort analysis was conducted from 2010 to 2018 using the Truven Health MarketScan database to estimate pneumococcal vaccination coverage among adults aged 19 to 64 years newly diagnosed with high-risk conditions, and to assess factors associated with receiving the recommended pneumococcal vaccines.Results: The study sample included 2,497,799 adults aged 19 to 64 years old with newly diagnosed high-risk conditions. Most of the study cohort had seven or more annual physician office (52%) and pharmacy (56%) visits. The proportion of high-risk adults who received at least one pneumococcal vaccination increased from 5.4% after 1 year of follow-up to 14.2% after 6 years of follow-up. Compared to those who received no pneumococcal vaccination, high-risk adults who received any pneumococcal vaccination were more likely to be older, female, enrolled in an HMO, had more healthcare encounters, and were treated by a primary care provider.Conclusion: Despite numerous healthcare encounters annually, very few high-risk adults received pneumococcal vaccines, highlighting the need for implementing targeted interventions to increase vaccine uptake in this vulnerable population.

Tumor Necrosis Factor Inhibitor Therapy and the Risk for Depression Among Working-Age Adults with Rheumatoid Arthritis.

BACKGROUND: Individuals with rheumatoid arthritis (RA) are at high risk for depression because of the overall burden of systemic inflammation. Although some evidence suggests that treatment with powerful anti-inflammatory drugs, such as tumor necrosis factor (TNF) inhibitors, may be effective in reducing the risk for depression in patients with RA, it is unclear whether such reduction in risk is dependent on the response to TNF inhibitor therapy. OBJECTIVE: To evaluate the association between the response to TNF inhibitor therapy and the risk for depression among working-age adults with RA. METHOD: This retrospective, observational cohort study design was based on data derived from commercial claims data in the QuintilesIMS Real World Data Adjudicated Claims database between October 1, 2009, and September 30, 2015. A total of 4222 working-age adults (18-62 years) with RA who started treatment with TNF inhibitor therapy and were continuously enrolled during the 3 observation periods (ie, 1-year baseline, 1-year treatment, and 1-year follow-up periods) were included in the study. Treatment response to a TNF inhibitor was measured using prescription drug claims based on a published validated algorithm. Multivariable logistic regression was used to examine the association between treatment response to TNF inhibitor therapy and the risk for depression, after controlling for baseline demographic characteristics, clinical characteristics, and RA-related medication use. An inverse probability of treatment weighting technique was used to control for observable differences in TNF inhibitor responders' characteristics versus TNF inhibitor nonresponders. RESULTS: Overall, 359 (8.5%) patients with RA had depression during the follow-up period and 1679 (39.8%) patients responded to TNF inhibitor treatment during the 1-year treatment period. A significantly lower percentage of TNF inhibitor responders (7.1%, N = 119) had depression than TNF inhibitor nonresponders (9.4%, N = 239). After controlling for other risk factors, responders to TNF inhibitors were 20% less likely to have depression during the follow-up period (adjusted odds ratio, 0.80; 95% confidence interval, 0.64-0.98) than nonresponders to TNF inhibitor therapy. CONCLUSION: The risk for depression was significantly reduced among patients with RA who responded to TNF inhibitor therapy compared with those who did not respond to such therapy. To determine whether the lower rate of depression observed with TNF inhibition is a direct effect of treatment with a TNF inhibitor, or whether it could be attributed to improvement in RA disease secondary to treatment, future studies need to also incorporate a control population of patients with RA who receive other antirheumatic regimens, such as disease-modifying antirheumatic drugs.

Burden of Depression among Working-Age Adults with Rheumatoid Arthritis.

OBJECTIVE: This study estimated the excess clinical, humanistic, and economic burden associated with depression among working-age adults with Rheumatoid Arthritis (RA). METHODS: A retrospective cross-sectional study was conducted among working-age (18 to 64 years) RA patients with depression (N = 647) and without depression (N = 2,015) using data from the nationally representative Medical Expenditure Panel Survey for the years 2009, 2011, 2013, and 2015. RESULTS: Overall, 25.8% had depression. In adjusted analyses, adults with RA and depression compared to those without depression were significantly more likely to have pain interference with normal work (severe pain: AOR = 2.22; 95% CI = 1.55, 3.18), functional limitations (AOR = 2.17; 95% CI = 1.61, 2.94), and lower mental health HRQoL scores. Adults with RA and depression had significantly higher annual healthcare expenditures ($14,752 versus 10,541, p < .001) and out-of-pocket spending burden. Adults with RA and depression were more likely to be unemployed and among employed adults, those with depression had a significantly higher number of missed work days annually and higher lost annual wages due to missed work days. CONCLUSIONS: This study highlights the importance of effectively managing depression in routine clinical practice of RA patients to reduce pain and functional limitations, improve quality of life, and lower direct and indirect healthcare costs.

Direct medical expenditures associated with Alzheimer's and related dementias (ADRD) in a nationally representative sample of older adults - an excess cost approach.

OBJECTIVE: To estimate the excess direct annual healthcare expenditures associated with Alzheimer's and related dementias(ADRD) among community-dwelling older adults in the United States. METHODS: This retrospective cross-sectional study compared the annual healthcare expenditures between elderly individuals aged 65 years and older with ADRD (n = 662) and without ADRD (n = 13,398) using data from the Medical Expenditure Panel Survey (MEPS) for the years 2007, 2009, 2011 and 2013. Adjusted total annual medical expenditures was estimated using generalized linear model with gamma distribution and log link in 2013 U.S. dollars. Adjusted inpatient, outpatient, emergency, home healthcare and prescription drug expenditures, were estimated using two-part logit-generalized linear regression models. RESULTS: The adjusted mean total healthcare expenditures were higher for the ADRD group as compared to the no ADRD group($14,508 vs. $10,096). Among those with ADRD, 34.3% of the expenditures were for home healthcare as compared to 4.4% among those without ADRD. Among users, the ADRD group had significantly higher home healthcare ($3,240 vs. $566) and prescription drug expenditures($3,471 vs. $2,471). There were no statistically significant differences in inpatient, emergency room and outpatient expenditures between the ADRD and no ADRD group. CONCLUSION: ADRD in U.S. community-dwelling elders is associated with significant financial burden, primarily driven by increased home healthcare use.

Persistence with rapid-acting insulin and its association with A1C level and severe hypoglycemia among elderly patients with type 2 diabetes.

OBJECTIVE: To examine the persistence with rapid-acting insulin (RAI) and its association with clinical outcomes among elderly patients with type 2 diabetes (T2D). METHODS: This observational, retrospective cohort study analyzed RAI persistence and its association with change in glycated hemoglobin A1c and risk of severe hypoglycemia among elderly (≥65 years) Medicare beneficiaries with T2D who added RAI to their basal insulin regimen. RESULTS: Among T2D patients with >1 RAI prescriptions (n = 3927), only 21% were persistent. Baseline factors positively associated with RAI persistence (adjusted odds ratio [95% CI]) were: age ≥75 vs. 65-74 years: 1.20 (1.01-1.43); use of ≥3 oral antidiabetes drugs: 1.63 (1.16-2.28); cognitive impairment: 1.34 (1.03-1.73); and A1C >9.0%: 1.58 (1.15-2.17). Elderly T2D patients having emergency department visits (0.73 [0.59-0.91]) and higher RAI out-of-pocket costs (≥$75 vs. $0 - <$6.40: 0.56 [0.44-0.70]) were less likely to be persistent. Persistent RAI users had a significantly higher reduction in A1C (beta coefficient [standard error]): -0.24 (0.10) and lower odds of severe hypoglycemia (adjusted odds ratio [95% CI]): 0.73 (0.53-0.99). CONCLUSION: Among elderly T2D patients, persistence with RAI added to basal insulin was associated with improved glycemic control and lower risk of severe hypoglycemia. Despite treatment effectiveness, RAI persistence was poor and might be improved by reducing RAI out-of-pocket costs.

Direct and indirect cost of managing alzheimer's disease and related dementias in the United States.

INTRODUCTION: Care of individuals with Alzheimer's Disease and Related Dementias (ADRD) poses special challenges. As the disease progresses, individuals with ADRD require increasing levels of medical care, caregiver support, and long-term care which can lead to substantial economic burden. Areas covered: In this expert review, we synthesized findings from studies of costs of ADRD in the United States that were published between January 2006 and February 2017, highlighted major sources of variation in costs, identified knowledge gaps and briefly outlined directions for future research and implications for policy and program planning. Expert commentary: A consistent finding of all studies comparing individuals with and without ADRD is that the average medical, non-medical, and indirect costs of individuals with ADRD are higher than those without ADRD, despite the differences in the methods of identifying ADRD, duration of the study, payer type and settings of study population. The economic burden of ADRD may be underestimated because many components such as direct non-medical costs for home safety modifications and adult day care services and indirect costs due to the adverse impact of ADRD on caregivers' health and productivity are not included in cost estimates.

Car Seat Safety: Typologies of Protective Health and Safety Behaviors for Mothers in West Virginia.

Objective Parenting practices differ for a variety of reasons, and three parenting behaviors may be directly influenced by research, policy, and overall parenting trends: car safety seats, vaccination, and breastfeeding. Mothers were categorized in terms of their rear-facing car safety seat utilization and its relationship to other parental health and safety behaviors. Methods A cross-sectional, online survey of mothers of children under 3 years of age (n = 124) was conducted. Items assessed mother's perceived risk and worry about being in an automobile accident, as well as duration of rear-facing car seat utilization. A cluster analysis based on these variables was performed to differentiate the sample into four distinct groups. Outcomes were knowledge of car safety seats, breastfeeding duration, and adherence to vaccination schedules. Results The sample was predominantly White, had an average age of 32 years, had breastfed, and had at least some college education. Two groups of interest had (Group 1) long duration of rear-facing use with low perceived risk and worry and (Group 2) short use with high perceived risk and worry. Fisher's Exact test indicated Group 1 had higher knowledge of airbag use with car seats (p = 0.035), lower intentions to use the recommended vaccinations schedule (p = 0.005), and were more likely to breastfeed (p = 0.044) for longer duration (p = 0.012). Conclusion Propensity for mothers' risk aversion may be the crucial element in both an appropriate duration of rear-facing car safety seat use and refusal of recommended vaccination schedule.

Depression treatment patterns among adults with chronic obstructive pulmonary disease and depression.

OBJECTIVE: To estimate rates and patterns of depression treatment among adults with chronic obstructive pulmonary disease (COPD) and depression. METHODS: We used a retrospective, cross-sectional study design, pooling data from 2010 and 2012 Medical Expenditure Panel Survey (MEPS). The study sample consisted of 527 individuals aged 21 years or older, diagnosed with COPD and depression. Depression treatment was grouped into three categories based on those who received: (1) neither antidepressant nor psychotherapy; (2) antidepressants only; and (3) psychotherapy combined with antidepressants (combination therapy). We conducted chi-squared tests and multinomial logistic regressions to examine factors (demographic, socio-economic characteristics, healthcare access, health status, and personal health practices) associated with depression treatment among adults with COPD and depression. KEY FINDINGS: The mean age of the study sample was 55.96 years (SD = 13.36). Overall, 18.8% of the sample adults did not report any use of antidepressants or psychotherapy, 58.3% reported antidepressants use only and 23% reported using combination therapy. Females (adjusted odds ratio [AOR] = 1.89, 95% CI = 1.02, 3.55), older adults (≥65 years: AOR = 3.69, 95% CI = 1.62, 8.41), adults with fair/poor physical health status (AOR = 3.32, 95% CI = 1.29, 8.56) and those suffering from anxiety (AOR = 1.94, 95% CI = 1.09, 3.46) were more likely to receive antidepressant treatment. Older adults (AOR =2.94, 95% CI = 1.05, 8.22), those who were never married (AOR = 3.17, 95% CI = 1.18, 8.56), suffered from anxiety (AOR =6.01, 95% CI = 3.11, 11.61) and current smokers (AOR = 2.29, 95% CI = 1.05, 4.98) were more likely to receive combination therapy. Whereas, adults who were uninsured (AOR = 0.21, 95% CI = 0.05, 0.86) and did not lacked regular physical activity (AOR = 0.33, 95% CI = 0.16, 0.67) were less likely to receive combination therapy. A key limitation of our study is that we could not control for the severity of depression or COPD which may have influenced depression treatment. CONCLUSION: Efforts to improve depression care among adults with co-occurring COPD and depression may need to be tailored for different subgroups.
