Psychotropic Medication Use among Medicare Beneficiaries Following Traumatic Brain Injury.

ABSTRACT: To characterize psychotropic medication use before and after traumatic brain injury (TBI) hospitalization among older adults. A secondary objective is to determine how receipt of indicated pharmacologic treatment for anxiety and post-traumatic stress disorder (PTSD) differs following TBI.Retrospective cohort.United States.Medicare beneficiaries aged ?65 years hospitalized with TBI between 2006 and 2010 with continuous drug coverage for 12 months before and after TBI (N?=?60,276).We obtained monthly psychotropic medication use by drug class and specific drugs from Medicare Part D drug event files.ICD-9 codes were used to define anxiety (300.0x) and PTSD (309.81).Average monthly prevalence of psychotropic medication use among all patients hospitalized for TBI was 44.8%; antidepressants constituted 73%. Prevalence of psychotropic medication use increased from 2006 to 2010. Following TBI, psychotropic medication use increased slightly (OR: 1.05; 95% CI: 1.03, 1.06.) Tricyclic antidepressant use decreased post-TBI (OR: 0.76; 95% CI: 0.73, 0.79) whereas use of the sedating antidepressants mirtazapine (OR: 1.31; 95% CI: 1.25, 1.37) and trazadone (OR: 1.11; 95% CI: 1.06, 1.17) increased. Antipsychotic (OR: 1.15; 95% CI: 1.12, 1.19) use also increased post-TBI. Beneficiaries newly diagnosed with anxiety (OR: 0.42; 95% CI: 0.36, 0.48) and/or PTSD (OR: 0.39; 95% CI: 0.18, 0.84) post-TBI were less likely to receive indicated pharmacologic treatment.Older adults hospitalized with TBI have a high prevalence of psychotropic medication use yet are less likely to receive indicated pharmacological treatment for newly diagnosed anxiety and PTSD following TBI.

Project description:ObjectiveTo describe psychotropic medication administration patterns during inpatient rehabilitation for traumatic brain injury (TBI) and their relation to patient preinjury and injury characteristics.DesignProspective observational cohort.SettingMultiple acute inpatient rehabilitation units or hospitals.ParticipantsIndividuals with TBI (N=2130; complicated mild, moderate, or severe) admitted for inpatient rehabilitation.InterventionsNot applicable.Main outcome measuresNot applicable.ResultsMost frequently administered were narcotic analgesics (72% of sample), followed by antidepressants (67%), anticonvulsants (47%), anxiolytics (33%), hypnotics (30%), stimulants (28%), antipsychotics (25%), antiparkinson agents (25%), and miscellaneous psychotropics (18%). The psychotropic agents studied were administered to 95% of the sample, with 8.5% receiving only 1 and 31.8% receiving ≥6. Degree of psychotropic medication administration varied widely between sites. Univariate analyses indicated younger patients were more likely to receive anxiolytics, antidepressants, antiparkinson agents, stimulants, antipsychotics, and narcotic analgesics, whereas those older were more likely to receive anticonvulsants and miscellaneous psychotropics. Men were more likely to receive antipsychotics. All medication classes were less likely administered to Asians and more likely administered to those with more severe functional impairment. Use of anticonvulsants was associated with having seizures at some point during acute care or rehabilitation stays. Narcotic analgesics were more likely for those with history of drug abuse, history of anxiety and depression (premorbid or during acute care), and severe pain during rehabilitation. Psychotropic medication administration increased rather than decreased during the course of inpatient rehabilitation in each of the medication categories except for narcotics. This observation was also true for medication administration within admission functional levels (defined by cognitive FIM scores), except for those with higher admission FIM cognitive scores.ConclusionsMany psychotropic medications are used during inpatient rehabilitation. In general, lower admission FIM cognitive score groups were administered more of the medications under investigation compared with those with higher cognitive function at admission. Considerable site variation existed regarding medications administered. The current investigation provides baseline data for future studies of effectiveness.

Project description:Diabetes mellitus, heart failure (HF), and chronic kidney disease are common comorbidities, but overall use and safety of antihyperglycemic medications (AHMs) among patients with these comorbidities are poorly understood.Using Get With the Guidelines-Heart Failure and linked Medicare Part D data, we assessed AHM use within 90 days of hospital discharge among HF patients with diabetes mellitus discharged from Get With the Guidelines-Heart Failure hospitals between January 1, 2006, and October 1, 2011. We further summarized use by renal function and assessed renal contraindicated AHM use for patients with estimated glomerular filtration rate <30 mL/min/1.73m(2). Among 8791 patients meeting inclusion criteria, the median age was 77 (interquartile range 71-83), 62.3% were female, median body mass index was 29.7 (interquartile range 25.5-35.3), median hemoglobin A1c was 6.8 (interquartile range 6.2-7.8), and 34% had ejection fraction <40%. 74.9% of patients filled a prescription for an AHM, with insulin (39.5%), sulfonylureas (32.4%), and metformin (17%) being the most commonly used AHMs. Insulin use was higher and sulfonylurea/metformin use was lower among patients with lower renal function classes. Among 1512 patients with estimated glomerular filtration rate <30 mL/min/1.73m(2), 35.4% filled prescriptions for renal contraindicated AHMs per prescribing information, though there was a trend toward lower renal contraindicated AHM use over time (Cochran-Mantel-Haenszel row-mean score test P=0.048). Although use of other AHMs was low overall, thiazolidinediones were used in 6.6% of HF patients, and dipeptidyl peptidase-4 inhibitors were used in 5.1%, with trends for decreasing thiazolidinedione use and increased dipeptidyl peptidase-4 inhibitor use over time (P<0.001).Treatment of diabetes mellitus in patients with HF and chronic kidney disease is complex, and these patients are commonly treated with renal contraindicated AHMs, including over 6% receiving a thiazolidinedione, despite known concerns regarding HF. More research regarding safety and efficacy of various AHMs among HF patients is needed.

Project description:BackgroundInformation regarding the use of glucose-lowering medications in patients with chronic kidney disease (CKD) is limited.Study designRetrospective cohort study.Setting & participantsMedicare 5% random sample of patients with CKD with type 2 diabetes, 2007 to 2016.PredictorsStudy year, CKD stage, low-income subsidy status, and demographic characteristics (age, sex, and race/ethnicity).OutcomesTrends in use of glucose-lowering medications.Analytical approachYearly cohorts of patients with CKD and type 2 diabetes were created. Descriptive statistics were used to report proportions of patients using glucose-lowering medications. To test overall trends in glucose-lowering medication classes, linear probability models with adjustment for age, sex, race/ethnicity, CKD stage, and low-income subsidy status were used.ResultsMetformin use increased significantly from 32.7% in 2007 to 48.7% in 2016. Use of newer classes of glucose-lowering medications increased significantly, including dipeptidyl peptidase 4 inhibitors (5.6%, 2007; 21.7%, 2016), glucagon-like peptide 1 receptor agonists (2.3%, 2007; 6.1%, 2016), and sodium-glucose cotransporter 2 inhibitors (0.2%, 2013; 3.3%, 2016). Newer insulin analogue use increased from 37.2% in 2007 to 46.3% in 2013 and then remained steady. Use of sulfonylureas, thiazolidinediones, older insulins (human regular and neutral protamine Hagedorn), α-glucosidase inhibitors, amylin mimetics, and meglitinides decreased significantly. Insulin was the most highly used single medication class. Insulin use was higher among low-income subsidy than among non-low-income subsidy patients. Combination therapy was less common as CKD stage increased.LimitationsPatients with CKD and type 2 diabetes and the CKD stages were identified with diagnosis codes and could not be verified through medical record review. Our results may not be generalizable to younger patients with CKD with type 2 diabetes.ConclusionsUse of metformin and newer glucose-lowering medication classes is increasing in patients with CKD with type 2 diabetes. We anticipate that percentages of patients with CKD using these newer agents will increase.

Project description:The cerebral correlates of altruistic decisions have increasingly attracted the interest of neuroscientists. To date, investigations on the neural underpinnings of altruistic decisions have primarily been conducted in healthy adults undergoing functional neuroimaging as they engaged in decisions to punish third parties. The chief purpose of the present study was to investigate altruistic decisions following focal brain damage with a novel altruistic decision task. In contrast to studies that have focused either on altruistic punishment or donation, the Altruistic Decision Task allows players to anonymously punish or donate to 30 charitable organizations involved with salient societal issues such as abortion, nuclear energy and civil rights. Ninety-four Vietnam War veterans with variable patterns of penetrating traumatic brain injury and 28 healthy veterans who also served in combat participated in the study as normal controls. Participants were asked to invest $1 to punish or reward real societal organizations, or keep the money for themselves. Associations between lesion distribution and performance on the task were analysed with multivariate support vector regression, which enables the assessment of the joint contribution of multiple regions in the determination of a given behaviour of interest. Our main findings were: (i) bilateral dorsomedial prefrontal lesions increased altruistic punishment, whereas lesions of the right perisylvian region and left temporo-insular cortex decreased punishment; (ii) altruistic donations were increased by bilateral lesions of the dorsomedial parietal cortex, whereas lesions of the right posterior superior temporal sulcus and middle temporal gyri decreased donations; (iii) altruistic punishment and donation were only weakly correlated, emphasizing their dissociable neuroanatomical associations; and (iv) altruistic decisions were not related to post-traumatic personality changes. These findings indicate that altruistic punishment and donation are determined by largely non-overlapping cerebral regions, which have previously been implicated in social cognition and moral experience such as evaluations of intentionality and intuitions of justice and morality.10.1093/brain/awy064_video1awy064media15758316955001.

Project description:ImportanceOne traumatic brain injury (TBI) increases the risk of subsequent TBIs. Research on longitudinal outcomes of civilian repetitive TBIs is limited.ObjectiveTo investigate associations between sustaining 1 or more TBIs (ie, postindex TBIs) after study enrollment (ie, index TBIs) and multidimensional outcomes at 1 year and 3 to 7 years.Design, setting, and participantsThis cohort study included participants presenting to emergency departments enrolled within 24 hours of TBI in the prospective, 18-center Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) study (enrollment years, February 2014 to July 2020). Participants who completed outcome assessments at 1 year and 3 to 7 years were included. Data were analyzed from September 2022 to August 2023.ExposuresPostindex TBI(s).Main outcomes and measuresDemographic and clinical factors, prior TBI (ie, preindex TBI), and functional (Glasgow Outcome Scale-Extended [GOSE]), postconcussive (Rivermead Post-Concussion Symptoms Questionnaire [RPQ]), psychological distress (Brief Symptom Inventory-18 [BSI-18]), depressive (Patient Health Questionnaire-9 [PHQ-9]), posttraumatic stress disorder (PTSD; PTSD Checklist for DSM-5 [PCL-5]), and health-related quality-of-life (Quality of Life After Brain Injury-Overall Scale [QOLIBRI-OS]) outcomes were assessed. Adjusted mean differences (aMDs) and adjusted relative risks are reported with 95% CIs.ResultsOf 2417 TRACK-TBI participants, 1572 completed the outcomes assessment at 1 year (1049 [66.7%] male; mean [SD] age, 41.6 [17.5] years) and 1084 completed the outcomes assessment at 3 to 7 years (714 [65.9%] male; mean [SD] age, 40.6 [17.0] years). At 1 year, a total of 60 participants (4%) were Asian, 255 (16%) were Black, 1213 (77%) were White, 39 (2%) were another race, and 5 (0.3%) had unknown race. At 3 to 7 years, 39 (4%) were Asian, 149 (14%) were Black, 868 (80%) were White, 26 (2%) had another race, and 2 (0.2%) had unknown race. A total of 50 (3.2%) and 132 (12.2%) reported 1 or more postindex TBIs at 1 year and 3 to 7 years, respectively. Risk factors for postindex TBI were psychiatric history, preindex TBI, and extracranial injury severity. At 1 year, compared with those without postindex TBI, participants with postindex TBI had worse functional recovery (GOSE score of 8: adjusted relative risk, 0.57; 95% CI, 0.34-0.96) and health-related quality of life (QOLIBRI-OS: aMD, -15.9; 95% CI, -22.6 to -9.1), and greater postconcussive symptoms (RPQ: aMD, 8.1; 95% CI, 4.2-11.9), psychological distress symptoms (BSI-18: aMD, 5.3; 95% CI, 2.1-8.6), depression symptoms (PHQ-9: aMD, 3.0; 95% CI, 1.5-4.4), and PTSD symptoms (PCL-5: aMD, 7.8; 95% CI, 3.2-12.4). At 3 to 7 years, these associations remained statistically significant. Multiple (2 or more) postindex TBIs were associated with poorer outcomes across all domains.Conclusions and relevanceIn this cohort study of patients with acute TBI, postindex TBI was associated with worse symptomatology across outcome domains at 1 year and 3 to 7 years postinjury, and there was a dose-dependent response with multiple postindex TBIs. These results underscore the critical need to provide TBI prevention, education, counseling, and follow-up care to at-risk patients.
