Trends of self-reported non-adherence among type 2 diabetes medication users in the United States across three years using the self-reported Medication Adherence Reasons Scale

Background & aimsTo determine the trends of self-reported non-adherence rates among adults taking Type 2 medicines (T2D) medicines between 2017 and 2019 and to identify the patterns for the frequently reported reasons for non-adherence in the United States.Methods & resultsData from the National Health and Wellness Survey, a self-administered, internet-based cross-sectional survey of US adults from 2017 to 2019 was used. Non-adherence was measured using the self-reported Medication Adherence Reasons Scale (MAR-Scale). Frequencies were used to identify the reasons for non-adherence for insulin and non-insulin therapies for T2D.Data were obtained from 2983 respondents in 2017, 5416 in 2018, and 5268 in 2019. Based on the MAR-Scale, the self-reported medication non-adherence rate was 25% in 2017, 21% in 2018, and 27% in 2019. The most common reason for non-adherence across all the three years was simple forgetfulness, yet patients reported the lowest mean number of days missing medication for that reason. Though less frequently reported, non-adherence lasted longer when patient did not know how to take their medicines, cost was a reason, or had concerns about the long term effects of the medicines.ConclusionsWith no significant improvement in adherence with T2D medicines over time, regardless of better awareness and extensive diabetes education, focus should be on individualized non-adherence reasons-based interventions.

Racial disparities in outcomes for extracorporeal membrane oxygenation in the United States

BackgroundRacial disparities in extracorporeal membrane oxygenation (ECMO) outcomes in patients with a broad set of indications are not well documented.MethodsAdults requiring ECMO were identified in the 2016–2019 National Inpatient Sample. Patient and hospital characteristics, including mortality, clinical outcomes, and resource utilization were analyzed using multivariable regressions.ResultsOf 43,190 adult ECMO patients, 67.8% were classified as White, 18.1% Black, and 10.4% Hispanic. Although mortality for Whites declined from 47.5 to 41.0% (P = 0.002), it remained steady for others. Compared to White, Asian/Pacific Islander (PI) race was linked to increased odds of mortalty (AOR = 1.4, 95% CI = 1.1–2.0). Black race was associated with increased odds of acute kidney injury (AOR = 1.4, 95%-CI: 1.2–1.7), while Hispanic race was linked to neurologic complications (AOR 21.6; 95% CI 1.2–2.3). Black and Hispanic race were also associated with increased incremental costs.ConclusionsRace-based disparities in ECMO outcomes persist in the United States. Further work should aim to understand and mitigate the underlying reasons for such findings.     

Understanding Hispanic Patient Satisfaction with Telehealth During COVID-19

BackgroundRecent studies have described the use of telehealth for pediatric surgical care during the COVID-19 pandemic. We aimed to evaluate equity in telehealth use by comparing rates of utilization and satisfaction with pediatric surgical telemedicine among Hispanic patients.MethodsWe conducted a retrospective cohort study of patients seen by a surgical subspecialty provider in the outpatient setting at a quaternary pediatric hospital between April 1 and June 30, 2020. Patients evaluated in the same three-month period in 2019 were analyzed as a historic control. Differences in Family Experience Survey (FES) responses based on race and ethnicity and preferred language of care were assessed using univariable and multivariable generalized linear modeling.ResultsThe pandemic cohort included fewer patients of Hispanic ethnicity and fewer Spanish-speakers. After controlling for visit type, comparison of Spanish-speaking and English-speaking patients revealed that Spanish-speaking families had significantly lower scores for FES items that evaluated healthcare provider explaining (IRR 0.74, 95% CI: 0.61–0.90), listening (IRR 0.76, 95% CI: 0.63–0.92), and time spent with the family (IRR 0.73, 95% CI: 0.60–0.89). There were no differences in FES responses based on insurance status or degree of medical complexity.ConclusionsTelehealth services were less commonly used among Hispanic and Spanish-speaking patients. Language may differentially affect family satisfaction with healthcare and telehealth solutions. Strategies to mitigate these inequities are needed and may include strengthening interpreter services and providing language-concordant care.Level of evidenceLevel IV.     

Study to assess existing knowledge of headache disorders among registered osteopaths practising in the UK: A cross-sectional survey

BackgroundHeadache disorders are highly prevalent worldwide. Many headache sufferers search for answers outside medical and pharmaceutical models. Complementary and alternative medicine (CAM) including osteopathy are widely used by headache patients. Indeed 9% of patients consulting osteopaths do so for headaches. There is no existing assessment of headache knowledge among practising Osteopaths in the UK.MethodsThis study was a cross-sectional survey employing an anonymous online questionnaire. An original questionnaire was developed. The scope was based on established guidelines in the primary care setting. Multiple choice and closed-ended questions assessed knowledge of the diagnostic criteria, potential red flags and appropriate investigations. The answers were informed by the International Classification Headache Disorder (ICHD-3) and the British Association for the Study of Headaches (BASH) guidelines. Three case vignettes relevant to osteopathic practice were included. Participants were invited to give optional free text feedback. The questionnaire was open to be self-completed by participants for 30 days.ResultsThere were 398 responders of which 383 were included and all of whom completed the questionnaire. The study found areas where knowledge was good, areas where it was limited and areas of uncertainty. The mean knowledge score was 6.93 out of 10 (range 2.18–9.42). There was a significantly lower mean knowledge score in those who had no prior headache education of −0.716 with a difference in means (−1.075 to −0.353, 95% C.I.) compared to those with prior education. Gender and years qualified had no significant effect on mean knowledge score. Optional free text feedback was given by 81 (21.2%) of the respondents and analyzed. The main themes were acknowledgment of knowledge gaps and a desire for more headache education.ConclusionThe findings suggest there are gaps in the existing knowledge on headache among UK osteopaths and the extent of this is dependent on prior headache education. We propose that ongoing headache education among osteopaths is needed in the field.     

Identifying developmental disability in national surveys: Addressing the knowledge gap with special education histories

BackgroundIn the United States nearly 20% of children ages 12–17 have developmental disorders. Some attain population-based developmental milestones after a delay, or increase functioning through special education, medication, technology, or therapy. Others have severe lasting impairments. An indicator identifying those groups in surveys of adults could help shape policies to improve lives.HypothesesWe hypothesized that survey histories of special education could indicate functional status levels.MethodsData were from the nationally representative Panel Study of Income Dynamics (1997–2017, n = 2745). With measures of diagnoses, behaviors, functional status, service use, and adult outcomes, we tested three special education groups as indicators of: (1) no impairment (no special education), (2) disorders, developmental diagnoses that adversely affect educational performance, but with development after a period of delay or only moderate disability, indicated by transfer from special education; and (3) severe lasting disability, the diagnoses combined with life-long needs for supports or services, with limitations in areas including self-care, mobility, and capacity for independent living, indicated by special education in the individual's final year of school.ResultsAcross the special education groups, from no impairment to severe lasting disability, there were trends of: increasing severe and lasting disability (respectively 4.8%, 35.6%, 76.4%); increasing special services use (13.5%, 43.1%, 83.7%); increasing severe emotional disorders (2.3%, 11.3%, 17.9%); lower percentages attaining at least an associate's degree by age 25 (42.1%, 20.7%, and 8.9%); and more chronic diseases.ConclusionsSpecial education histories provide a useful indicator of developmental disability impairment levels in adults.     

Compliance to Advisory Committee on Immunization Practices recommendations for pneumococcal vaccination

We evaluated compliance to the ACIP pneumococcal vaccination recommendations issued in 2014 for adults aged ≥ 65 years and in 2012 for adults with high-risk (HR) conditions. The MarketScan® Commercial and Medicare Supplemental databases (January 2007-June 2019) were used to identify the cohorts of interest. Analyses for adults aged ≥ 65 years were adjusted to account for missing vaccination history. Two HR cohorts were identified. The HR1 cohort included patients with immunocompromising conditions, functional or anatomic asplenia, cerebrospinal fluid leak, or cochlear implant. The HR2 cohort included patients with chronic heart, lung, or liver disease; diabetes mellitus; alcoholism; cirrhosis; or cigarette smoking. Full compliance for those aged ≥ 65 years or in the HR1 cohort was defined as receipt of PCV13 and PPSV23, and partial compliance was defined as receipt of PCV13 or PPSV23. For those in the HR2 cohort, full compliance was defined as receipt of PPSV23. Annual compliance rates were estimated using the Kaplan–Meier method.Among those aged ≥ 65 years, partial compliance at 4 years post index was 53% and full compliance was 17% in adjusted analyses. In subjects ≥ 65 years receiving the first vaccination, 42% received the second vaccination by year 4. For the HR1 cohort, partial compliance was 19% and full compliance was 5% at 6 years post index date. For the HR2 cohort, full compliance was 20% at 6 years, with the highest rate in patients with diabetes (27%) and the lowest rate in patients with alcoholism (8%).Additional efforts are needed to maximize compliance to the ACIP pneumococcal vaccine recommendations among adults ≥ 65 years of age and adults with HR conditions including streamlined recommendations and single-dose vaccines. These efforts may subsequently reduce the incidence and burden of pneumococcal disease.
