Susceptibility to quinoline antimalarial intoxication may reflect individual genetic and drug-induced variation in neuropharmacokinetics. In this report, we describe a case of chloroquine intoxication that appeared to be prolonged by subsequent use of multiple psychotropic medications. This case highlights important new considerations for the management of quinoline antimalarial intoxication. ...[more]

Project description:AimsTo describe psychotropic polypharmacy in Australia between 2006 and 2015.MethodsWe used pharmaceutical claims from a national 10% sample of people with complete dispensing histories to estimate the annual prevalence of the combined use (overlap of >60 days exposure) of ≥2 psychotropics overall and within the same class or subclass (class and subclass polypharmacy). We also estimated the proportion of polypharmacy episodes involving one, two, three and four or more unique prescribers.ResultsThe prevalence of class polypharmacy between 2006 and 2015 in people dispensed specific psychotropic classes was 5.9-7.3% for antipsychotics, 2.1-3.7% for antidepressants and 4.3-2.9% for benzodiazepines. The prevalence of antipsychotic polypharmacy was higher than expected given the prevalence of antipsychotic exposure and combinations of sedating agents were notably common. Overall, 26.7% of polypharmacy episodes involved multiple prescribers but having multiple prescribers occurred more frequently for class and subclass polypharmacy and people with four or more concomitant psychotropics.DiscussionPsychotropic polypharmacy is common, despite limited evidence of risks and benefits. Increases in polypharmacy with multiple prescribers may be due to poor communication with patients and between health care professionals.

Project description:ObjectiveThe objectives of this study were to examine rates and predictors of psychotropic use and multiclass polypharmacy among commercially insured children with autism spectrum disorders (ASD).MethodsThis retrospective observational study used administrative medical and pharmacy claims data linked with health plan enrollment and sociodemographic information from 2001 to 2009. Children with ASD were identified by using a validated ASD case algorithm. Psychotropic polypharmacy was defined as concurrent medication fills across ≥ 2 classes for at least 30 days. Multinomial logistic regression was used to model 5 categories of psychotropic use and multiclass polypharmacy.ResultsAmong 33,565 children with ASD, 64% had a filled prescription for at least 1 psychotropic medication, 35% had evidence of psychotropic polypharmacy (≥ 2 classes), and 15% used medications from ≥ 3 classes concurrently. Among children with polypharmacy, the median length of polypharmacy was 346 days. Older children, those who had a psychiatrist visit, and those with evidence of co-occurring conditions (seizures, attention-deficit disorders, anxiety, bipolar disorder, or depression) had higher odds of psychotropic use and/or polypharmacy.ConclusionsDespite minimal evidence of the effectiveness or appropriateness of multidrug treatment of ASD, psychotropic medications are commonly used, singly and in combination, for ASD and its co-occurring conditions. Our results indicate the need to develop standards of care around the prescription of psychotropic medications to children with ASD.

Project description:PurposeAccording to the revised Japanese medical service fees aimed at reducing irrational psychotropic polypharmacy, medical service fees are reduced if the number of simultaneously prescribed psychotropic drugs exceeds the standard. This study primarily aims to examine the effect of the 2018 revision.MethodsUsing a large Japanese administrative claims database, we retrospectively identified five groups (April 2013-September 2018) prescribed at least one drug from the following drug groups: anxiolytics, hypnotics, sum of anxiolytics and hypnotics, antipsychotics, and antidepressants (study population in each group: 547,511, 406,524, 759,137, 112,929, and 201,046, respectively). We used an interrupted time-series design to evaluate changes in the proportion of patients prescribed more than the standard number of drugs.ResultsAfter the 2018 revision, the proportion of patients prescribed more than the standard number of drugs significantly decreased only for the sum of anxiolytics and hypnotics; estimated changes in level and trend were - 0.60% [- 0.69%, - 0.52%] and - 0.04% [- 0.06%, - 0.02%] per month, respectively. The proportion of patients exhibiting a decrease in the number of prescribed drugs from more than the standard to within the standard increased when the revision was enforced (April 2018); this proportion in April 2018 was 36.3%, while all other proportions were in the range of 12.1-22.3%.ConclusionThe 2018 revision promoted a reduction in the number of prescribed drugs, which served as an important factor in the decrease in the proportion of patients prescribed more than the standard number of drugs for the sum of anxiolytics and hypnotics.

Project description:ObjectiveThis study examined polypharmacy patterns and rates over time among Medicaid-enrolled youths by comparing three enrollment groups (youths in foster care, with a disability, or from a family with low income).MethodsSerial cross-sectional trend analyses of Medicaid claims data were conducted for youths age 17 and younger who were continuously enrolled in Ohio Medicaid for a one-year period and prescribed one or more psychotropic medications during fiscal years 2002 (N=26,252) through 2008 (N=50,311). Outcome measures were any polypharmacy (three or more psychotropic medications from any drug class) and multiclass polypharmacy (three or more psychotropic medications from different drug classes).ResultsBoth types of polypharmacy increased across all three eligibility groups. Any polypharmacy increased from 8.8% to 11.5% for low-income youths (adjusted odds ratio [AOR]=1.12, 99% confidence interval [CI]=1.10-1.13), from 18.0% to 24.9% for youths with a disability (AOR=1.11, CI=1.09-1.13), and from 19.8% to 27.3% for youths in foster care (AOR=1.09, CI=1.07-1.11). Combinations associated with positive increases were two or more antipsychotics, two or more stimulants, and antipsychotics with stimulants.ConclusionsPolypharmacy increased across all enrollment groups, with the highest absolute rates for youths in foster care. Both the overall prevalence and increases in prescriptions for drug combinations with limited evidence of safety and efficacy, such as the prescription of two or more antipsychotics, underscore the need for targeted quality improvement efforts. System oversight and monitoring of psychotropic medication use appears to be warranted, especially for higher-risk groups, such as youths in foster care and those from low-income households who were prescribed multiple antipsychotics.

Project description:Background/objectivesThere are growing concerns about the safety and efficacy of psychotropic medications in Alzheimer's disease (AD). We sought to examine associations between psychotropic medication exposure and longitudinal change in cognitive, functional, and neuropsychiatric outcomes in a large clinical AD cohort.DesignLongitudinal observational study.SettingNational Alzheimer's Disease Coordinating Center combining data from 39 Alzheimer's disease centers.Participants8,034 participants with AD dementia.MeasurementsMini-Mental State Exam (MMSE), Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB), and Neuropsychiatric Inventory Questionnaire (NPI-Q) Total. Probability of exposure to medication (the propensity score, PS) calculated via logistic regression. Medication classes included all antipsychotics (atypical vs conventional), antidepressants (Selective Serotonin Reuptake Inhibitor [SSRI] vs non-SSRI), and benzodiazepines. Participants treated with a medication class were matched with participants not treated with that class with the closest-matched PS. The effect of medication treatment was assessed using linear mixed-effects models.ResultsParticipants had a mean (SD) age of 75.5 (9.8) years, and mean (SD) scores of MMSE 21.3 (5.7), CDR-SB 5.5 (3.4), and NPI-Q Total 4.5 (4.4). Mean duration of follow-up was 2.9-3.3 years depending on medication class. Non-SSRI antidepressant use was associated with better CDR-SB (2-year difference in change-DIC: -0.38 [-0.61, -0.15], P = .001). Atypical antipsychotic use was associated with greater decline on MMSE (DIC: -0.91 [-1.54, -0.28] P = .005) and CDR-SB scores (DIC: 0.50 [0.14, 0.86], P = .006). Notably, no drug class was associated with better NPI-Q scores.ConclusionsUse of atypical antipsychotics was associated with poorer cognition and function, and no drug class was associated with improvement in neuropsychiatric symptoms.

Project description:BackgroundPolypharmacy is common in people with dementia. The use of psychotropic drugs (PDs) and other, potentially inappropriate medications is high. The aims of this cross-sectional study were 1) to investigate the use of drugs in people with advanced dementia (PWAD), living at home or in long term care (LTC); 2) to focus on PD use; and 3) to identify determinants of PD use.MethodsThe study was performed in the context of EPYLOGE (IssuEs in Palliative care for people in advanced and terminal stages of YOD and LOD in Germany). 191 PWAD were included. All drugs that were administered at the date of the examination were recorded. Multiple logistic regression analysis identified determinants of PD use.Results96% of PWAD received medication with a median number of four drugs. 49.7% received five or more drugs. According to the Beers Criteria 39% of PWAD ≥ 65 years received at least one potentially inappropriate medication. 79% of PWAD were treated with PDs. Older PWAD and PWAD living in LTC facilities received significantly more drugs than younger PWAD, and PWAD living at home, respectively. Dementia etiology was significantly associated with the use of antipsychotics, antidepressants and sedative substances. Place of living was associated with the use of pain medication. Behavioral disturbances were associated with the use of antipsychotics and sedative substances.ConclusionsTo mitigate the dangers of polypharmacy and medication related harm, critical examination is required, whether a drug is indicated or not. Also, the deprescribing of drugs should be considered on a regular basis.Trial registrationClinicaltrial.gov, NCT03364179 . Registered 6 December 2017.

Project description:To determine the national prevalence of psychotropic use and association with neuropsychiatric symptoms among patients with dementia.Participants diagnosed with dementia (n?=?414) in the Aging, Demographics, and Memory Study, a nationally representative survey of US adults >70?years old. Diagnosis was based on in-person clinical assessment and informant interview. Information collected included demographics, place of residence, 10-item Neuropsychiatric Inventory (NPI), and prescribed medications (antipsychotic, sedative-hypnotic, antidepressant, mood stabilizer).Of 414 participants with dementia, 41.4% were prescribed a psychotropic medication, including 84.0% of nursing home residents and 28.6% of community-dwellers. Of participants, 23.5% were prescribed an antidepressant. Compared with the total NPI score of those on no medication (4.5), those on antipsychotics and those on sedative-hypnotics had much higher scores (respectively: 12.6, p?<?0.001; 11.8, p?=?0.03), although those antidepressants did not (6.9, p?=?0.15). A larger proportion of patients on antipsychotics exhibited psychosis and agitation compared with those on no medication, while those on antidepressants exhibited more depressive symptoms. In multivariable logistic regression that included dementia severity and nursing home residence, nursing home residence was the characteristic most strongly associated with psychotropic use (odds ratio ranging from 8.96 [p?<?0.001] for antipsychotics to 15.59 [p?<?0.001] for sedative-hypnotics). More intense psychotic symptoms and agitation were associated with antipsychotic use; more intense anxiety and agitation were associated with sedative-hypnotic use. More intense depression and apathy were not associated with antidepressant use.In this nationally representative sample, 41.4% of patients were taking psychotropic medication. While associated with neuropsychiatric symptoms, nursing home residence was most strongly tied to use. Copyright © 2016 John Wiley & Sons, Ltd.

Project description:Objective: Little research has evaluated trends in psychotropic prescribing and polypharmacy in primary care patients, especially those with dementia. We sought to examine this in Australia from 2011 to 2020 using the primary care dataset, MedicineInsight. Methods: Ten consecutive serial cross-sectional analyses were performed to evaluate the proportion of patients aged 65 years or more, with a recorded diagnosis of dementia, who were prescribed psychotropic medications within the first six months of each year from 2011 to 2020. This proportion was compared with propensity score-matched control patients without dementia. Results: Before matching, 24,701 patients (59.2% females) with, and 72,105 patients (59.2% females) without, a recorded diagnosis of dementia were included. In 2011, 42% (95% confidence interval [CI] 40.5–43.5%) of patients in the dementia group had at least one recorded prescription of a psychotropic medication, which declined to 34.2% (95% CI 33.3–35.1%; p for trend < 0.001) by 2020. However, it remained unchanged for matched controls (36% [95% CI 34.6–37.5%] in 2011 and 36.7% [95% CI 35.7–37.6%] in 2020). The greatest decline in the dementia groups by medication class was for antipsychotics (from 15.9% [95% CI 14.8–17.0%] to 8.8% [95% CI 8.2–9.4%]; p for trend < 0.001). During this period, the prevalence of psychotropic polypharmacy (use of two or more individual psychotropics) also decreased from 21.7% (95% CI 20.5–22.9%) to 18.1% (95% CI 17.4–18.9%) in the dementia groups, and slightly increased from 15.2% (95% CI 14.1–16.3%) to 16.6% (95% CI 15.9–17.3%) in the matched controls. Conclusions: The decline in psychotropic prescribing, particularly antipsychotics, in Australian primary care patients with dementia is encouraging. However, psychotropic polypharmacy still occurred in almost one in five patients with dementia at the end of the study period. Programs focused on encouraging further reductions in the use of multiple psychotropic drugs in patients with dementia are recommended, particularly in rural and remote regions.
