BACKGROUND/OBJECTIVES: Guideline-based management of cardiovascular disease often involves prescribing multiple medications, which contributes to polypharmacy and risk for adverse drug events in older adults. Deprescribing is a potential strategy to mitigate these risks. We sought to characterize and compare clinician perspectives regarding deprescribing cardiovascular medications across three specialties.

DESIGN: National cross-sectional survey.

SETTING: Ambulatory.

PARTICIPANTS: Random sample of geriatricians, general internists, and cardiologists from the American College of Physicians.

MEASUREMENTS: Electronic survey assessing clinical practice of deprescribing cardiovascular medications, reasons and barriers to deprescribing, and choice of medications to deprescribe in hypothetical clinical cases.

RESULTS: In each specialty, 750 physicians were surveyed, with a response rate of 26% for geriatricians, 26% for general internists, and 12% for cardiologists. Over 80% of respondents within each specialty reported that they had recently considered deprescribing a cardiovascular medication. Adverse drug reactions were the most common reason for deprescribing for all specialties. Geriatricians also commonly reported deprescribing in the setting of limited life expectancy. Barriers to deprescribing were shared across specialties and included concerns about interfering with other physicians' treatment plans and patient reluctance. In hypothetical cases, over 90% of physicians in each specialty chose to deprescribe when patients experienced adverse drug reactions. Geriatricians were most likely and cardiologists were least likely to consider deprescribing cardiovascular medications in cases of limited life expectancy (all P < .001), such as recurrent metastatic cancer (84% of geriatricians, 68% of general internists, and 45% of cardiologists), Alzheimer dementia (92% of geriatricians, 81% of general internists, and 59% of cardiologists), or significant functional impairment (83% of geriatricians, 68% of general internists, and 45% of cardiologists).

CONCLUSIONS: While barriers to deprescribing cardiovascular medications are shared across specialties, reasons for deprescribing, especially in the setting of limited life expectancy, varied. Implementing deprescribing will require improved processes for both physician-physician and physician-patient communication. J Am Geriatr Soc 68:78-86, 2019.

(2020) 2020. “Prevalence of Diabetes Medication Intensifications in Older Adults Discharged From US Veterans Health Administration Hospitals.”. JAMA Network Open 3 (3): e201511. https://doi.org/10.1001/jamanetworkopen.2020.1511.

IMPORTANCE: Elevated blood glucose levels are common in hospitalized older adults and may lead clinicians to intensify outpatient diabetes medications at discharge, risking potential overtreatment when patients return home.

OBJECTIVE: To assess how often hospitalized older adults are discharged with intensified diabetes medications and the likelihood of benefit associated with these intensifications.

DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study examined patients aged 65 years and older with diabetes not previously requiring insulin. The study included patients who were hospitalized in a Veterans Health Administration hospital for common medical conditions between 2011 and 2013.

MAIN OUTCOMES AND MEASURES: Intensification of outpatient diabetes medications, defined as receiving a new or higher-dose medication at discharge than was being taken prior to hospitalization. Mixed-effect logistic regression models were used to control for patient and hospitalization characteristics.

RESULTS: Of 16 178 patients (mean [SD] age, 73 [8] years; 15 895 [98%] men), 8535 (53%) had a preadmission hemoglobin A1c (HbA1c) level less than 7.0%, and 1044 (6%) had an HbA1c level greater than 9.0%. Overall, 1626 patients (10%) were discharged with intensified diabetes medications including 781 (5%) with new insulins and 557 (3%) with intensified sulfonylureas. Nearly half of patients receiving intensifications (49% [791 of 1626]) were classified as being unlikely to benefit owing to limited life expectancy or already being at goal HbA1c, while 20% (329 of 1626) were classified as having potential to benefit. Both preadmission HbA1c level and inpatient blood glucose recordings were associated with discharge with intensified diabetes medications. Among patients with a preadmission HbA1c level less than 7.0%, the predicted probability of receiving an intensification was 4% (95% CI, 3%-4%) for patients without elevated inpatient blood glucose levels and 21% (95% CI, 15%-26%) for patients with severely elevated inpatient blood glucose levels.

CONCLUSIONS AND RELEVANCE: In this study, 1 in 10 older adults with diabetes hospitalized for common medical conditions was discharged with intensified diabetes medications. Nearly half of these individuals were unlikely to benefit owing to limited life expectancy or already being at their HbA1c goal.

BACKGROUND: Limited English proficiency is associated with decreased access to ambulatory care, however, it is unclear if this disparity leads to increased use of emergency departments (EDs) for low severity ambulatory care sensitive conditions (ACSCs).

OBJECTIVE: We sought to determine the association between the patient's preferred language and hospital utilization for ACSCs.

RESEARCH DESIGN: We conducted a retrospective cohort study of all ED visits in New Jersey in 2013 and 2014. The primary outcome was hospital admission for acute ACSCs, chronic ACSCs, and fractures (a nonambulatory care sensitive control condition). Secondary outcomes included intensive care unit (ICU) utilization and length of stay. Mixed-effect regression models estimated the association between preferred language (English vs. non-English) and study outcomes, controlling for demographics, comorbidities, and hospital characteristics.

RESULTS: We examined 201,351 ED visits for acute ACSCs, 251,193 visits for chronic ACSCs, and 148,428 visits for fractures, of which 13.5%, 11.1%, and 9.9%, respectively, were by non-English speakers. In adjusted analyses, non-English speakers were less likely to be admitted for acute ACSCs [-3.1%; 95% confidence interval (CI), -3.6% to -2.5%] and chronic ACSCs (-2.3%; 95% CI, -2.8% to -1.7%) but not fractures (0.4%; 95% CI, -0.2% to 1.0%). Among hospitalized patients, non-English speakers were less likely to receive ICU services but had no difference in length of stay.

CONCLUSIONS: These findings suggest non-English-speaking patients may seek ED care for lower acuity ACSCs than English-speaking patients. Efforts to decrease preventable ED and increase access to ambulatory care use should consider the needs of non-English-speaking patients.

(2020) 2020. “Adolescent Reproductive and Sexual Coercion: Measurement Invariance in a Population-Based Sample of Male and Female High School Students.”. Journal of Family Violence 35 (6): 619-32. https://doi.org/10.1007/s10896-019-00092-w.

PURPOSE: Though researchers have documented that adolescents are vulnerable to coercion focused on reproductive and sexual autonomy, measures to assess this type of coercion for both adolescent females and males have not been validated in a population-based sample.

METHOD: The present study used secondary data collected from high school students across Kentucky (n=16,137 from two independent samples in 2010 and 2014) to 1) determine if five items measuring adolescent reproductive and sexual coercion (ARSC) are appropriate for use among both females and males; and 2) estimate prevalence of identified ARSC factors by sex.

RESULTS: For both male and females, given measurement items, the results supported a two-factor model of ARSC comprised of 1) verbal relationship manipulation and 2) contraceptive interference. Measurement invariance by sex was also supported. Additional findings indicated the high prevalence of ARSC and its associated subscales. Approximately 4 in 10 females and 3 in 10 males reported experiencing ARSC in the previous year, with almost all of those reporting contraceptive interference also reporting verbal relationship manipulation.

CONCLUSIONS: Findings suggest verbal relationship manipulation and contraceptive interference (together forming ARSC) may restrict the autonomous sexual and reproductive decision-making of both female and male adolescents.
