Cardiovascular Risk of Concomitant Use of Atypical Antipsychotics and Stimulants Among Commercially Insured Youth in the United States.

ABSTRACT: Objectives: To investigate the risk of cardiovascular events associated with concomitant use of stimulants and atypical antipsychotics (AAPs) among youth and evaluate whether AAP dose and duration of concomitant use modifies the risk. Methods: We used IQVIA PharMetrics® Plus data from 2006 to 2015 to construct a retrospective cohort of commercially-insured youth aged 5-17 years old who initiated a stimulant medication. Time-varying concomitant stimulant/AAP use was defined as current, past and no concomitant use based on person months. The primary time-varying Cox proportional hazard regression analysis evaluated the risk of cardiovascular events comparing current concomitant use with past and no concomitant use, adjusted for baseline cardiovascular risk. A secondary analysis assessed the risk of cardiovascular events comparing AAP daily doses (<1, 1-2, >2 mg) and duration (<3, 3-6, >6 months) of current concomitant use to no concomitant use. Cardiovascular outcomes included severe (i.e., stroke, acute myocardial infarction, ischemic heart disease) and less severe (i.e., angina pectoris, cardiac dysrhythmias, transient cerebral ischemia, hypertensive disease, tachycardia, palpitations, syncope). Results: For this cohort of 61,438 youths, the incidence rate of severe cardiovascular events was 0.18 per 10,000 person-months, and all events occurred in no concomitant use months. The risk of less severe cardiovascular events was significantly higher in current concomitant users compared with no [HR: 2.59 (95%CI: 1.72, 3.90)] and past [HR: 1.89 (95%CI: 1.10, 3.24)] concomitant users. Compared to no concomitant use, the risk of less severe cardiovascular events was significantly higher at all AAP daily doses [HR: <1 mg: 2.82 (95%CI: 1.72, 4.61); 1-2 mg: 2.22 (95%CI: 1.16, 4.25); >2 mg: 2.65 (95%CI: 1.50, 4.71)]. The risk of less severe cardiovascular events significantly elevated for all duration of use and was higher for <3 months of concomitant use [HR: <3 months: 3.45 (95%CI: 2.17, 5.47) relative to 3-6 months: 2.60 (95%CI: 1.29, 5.25) or >6 months: 2.61 (95%CI: 1.59, 4.30)]. Conclusions: Severe cardiovascular events are rare. Concomitant stimulant/AAP use elevates the risk of less severe cardiovascular events. Periodic heart rate or blood pressure monitoring for youth on stimulant/AAP treatment may be warranted.

Project description:ObjectiveTo compare the type, frequency, and timing of health care use among commercially insured postpartum and nonpostpartum women.MethodsThis retrospective cohort study used data from a large national commercial claims database. Women between 18 and 44 years of age who gave birth in 2016 (n=149,563) and women who were neither pregnant nor postpartum between 2015 and 2017 (n=2,048,831) (nonpostpartum) were included. We examined hospitalization, and preventive visits, problem visits, and emergency department (ED) visits among postpartum women during the early postpartum period (less than 21 days after childbirth), the postpartum period (21-60 days postpartum), and extended postpartum period (61-365 days after childbirth). Visits among nonpostpartum women were assessed during time periods of equivalent duration.ResultsAlmost 24% of postpartum women had a problem visit in the early postpartum period, compared with 19.7% of nonpostpartum women (adjusted difference 4.8 percentage points [95% CI 4.6-5.0]). Approximately 3% of postpartum women had an early ED visit, more than double the percentage among nonpostpartum women (adjusted difference 2.3 percentage points [95% CI 2.2-2.4]). Both problem visits and ED visits among postpartum women remained elevated relative to nonpostpartum women during the postpartum and extended postpartum periods. Although postpartum women were more likely than nonpostpartum women to receive preventive care during the early and postpartum periods, only 43% of postpartum women had a preventive visit during the extended postpartum period, a rate 1.8 (95% CI -2.1 to -1.5) percentage points lower than that of nonpostpartum women. Adjusted hospitalization rates among postpartum women in the early (0.8%), postpartum (0.3%), and extended postpartum (1.4%) periods were higher than those of nonpostpartum women (0.1%, 0.2%, and 1.6%, respectively).ConclusionsCommercially insured postpartum women use more health care than nonpostpartum women, including inpatient care. Differences are largest in the early postpartum period and persist beyond 60 days postpartum.

Project description:Objectives: To assess the use of three commonly prescribed psychotropic medications in youth placed in residential care (RC). Methods: Participants were youth aged 0-20 years placed in RC institutions at least once during 2016. Data on filled prescriptions were taken from the Norwegian Prescription Database to compare the use of antidepressants, antipsychotics, and stimulants in RC with the age- and gender-adjusted general child population (GenPop) and how this co-varied with reasons for RC placement, age, and gender. Results: One thousand eight hundred fifty-six children and adolescents were identified in RC, with mean age 14 (range 0-20 years), 46% girls, 81% ≥ 13 years. Among those, 423 or 23% used any of the 3 psychotropics, which was significantly more than the 3.7% in GenPop. The prevalence ratios RC/GenPop were 6.6 for antidepressants, 17.9 for antipsychotics, and 4.4 for stimulants. The median number of days per year for the dispensed defined daily doses varied from 8.3 to 244.0 for the different antipsychotics, indicating short time use for most of the people. Polypharmacy was not frequent in RC, as only 26% used ≥2 classes of medication, but still significantly more frequent than the 10% in GenPop. Youth placed in RC for serious behavior problems had significantly higher use of stimulants than those with other placement reasons. Psychotropics were not used below age 6 years, and although the use of antidepressants and antipsychotics overall increased with age, stimulants were mostly used by 6-16-year olds. The girl/boy ratio for any psychotropic medication use in RC was 1.4 (95% confidence interval [95% CI]: 1.1-1.6), significantly higher than the corresponding ratio in GenPop: 1.0 (95% CI: 0.9-1.0). Conclusion: The present findings do not necessarily suggest an overtreatment with medication in RC. However, the frequent short-term use of antipsychotics, presumably for non-psychotic symptoms, is a concern, as it may reflect that the youth are not provided with the recommended first-line psychological treatments.

Project description:ObjectiveTo estimate the economic burden of systematic lupus erythematous (SLE), stratified by disease severity, in commercially- and Medicaid-insured US populations.MethodsAdults (≥18 years) with SLE treated with antimalarials, selected biologics, immunosuppressants, and systemic glucocorticoids (2010-2014) were identified within the commercial and Medicaid insurance IBM MarketScan® databases (index date = first SLE medication claim). Both cohorts were stratified into mild (receiving antimalarial or glucocorticoid monotherapy ≤5 mg/day) versus moderate/severe SLE (receiving glucocorticoids >5 mg/day, biologic, immunosuppressant, or combination therapy) during a 6-month exposure period. All-cause healthcare utilization and costs were evaluated during the 12 months following the exposure period.ResultsAmong 8231 commercially-insured patients, 32.6% had mild and 67.4% had moderate/severe SLE by our definition. Among 802 Medicaid-insured patients, 25.2% had mild and 74.8% had moderate/severe SLE. Adjusted mean total healthcare costs, excluding pharmacy, for moderate/severe SLE patients were higher than for mild SLE patients in the commercially-insured ($39,021 versus $23,519; p < 0.0001) and Medicaid-insured populations ($56,050 versus $44,932; p = 0.06). In both SLE severity populations total unadjusted costs were significantly higher among Medicaid-insured than commercially-insured patients.ConclusionCommercially-insured patients with treatment suggesting moderate/severe SLE incurred significantly higher adjusted mean healthcare costs, excluding pharmacy, compared with mild SLE patients. While not reaching statistical significance, moderate/severe Medicaid-insured patients had higher costs then mild SLE patients. Total unadjusted healthcare costs were significantly higher among Medicaid-insured than commercially-insured patients. These differential costs are important to consider and monitor when implementing interventions to improve health and reduce healthcare spending for SLE.
