Soc Psychiatry Psychiatr Epidemiol 2024; 59:799-811. [PMID: 37847256 DOI: 10.1007/s00127-023-02574-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 09/28/2023] [Indexed: 10/18/2023]
Abstract
PURPOSE This longitudinal study aimed to examine the trends in antipsychotics, antidepressants, anxiolytics, and hypnotics/sedatives consumption in Croatia over a 10-year period (2012-2021). The study also assessed whether the COVID-19 pandemic had an impact on the yearly consumption of psychotropic drugs. METHODS Data were collected from Croatian Agency for Medicinal Products and Medical Devices (HALMED) and presented as defined daily doses per 1000 inhabitants per day (DDD/TID). The consumption before (2012-2019) and during the COVID-19 pandemic (2020-2021) was compared with interrupted time series analysis. RESULTS There was an increase in total consumption of analyzed psychotropic drugs in Croatia between the years 2012 and 2021, from 115.47 DDD/TID in 2012 to 155.50 DDD/TID in 2021. An increasing trend was observed in the consumption of all 4 analyzed groups of medicines (antipsychotics, anxiolytics, hypnotics and sedatives, and antidepressants). Anxiolytics accounted for 59% (68.29/115.47 DDD/TID), and hypnotics and sedatives for 8.5% (9.76/115.47 DDD/TID) of total consumption in 2012. At the end of a 10-year period, hypnotics and sedatives represented 12% (19.05/155.50 DDD/TID) and anxiolytics 54% (83.53/155.50 DDD/TID) of psychotropic drugs consumption. The total consumption of psychotropic drugs was not significantly different before and during COVID-19 pandemic (estimate ± standard error = 5.029 ± 6.899, t = 0.729, P = 0.490). CONCLUSION Croatia had a high, continuously increasing consumption of psychotropic drugs. National anxiolytics consumption was one of the highest globally, while consumption of antidepressants was rather low compared to other high-income countries. The COVID-19 pandemic did not seem to influence the yearly utilization of psychotropic drugs in Croatia.

Abstract
BACKGROUND Psychotropic medicine utilisation in older adults continues to be of interest because of overuse and concerns surrounding its safety and efficacy. OBJECTIVE This study aimed to characterise the utilisation of psychotropic medicines in older people in New Zealand. METHODS We conducted a repeated cross-sectional analysis of national dispensing data from 1 January, 2005 to 31 December, 2019. We defined utilisation using the Anatomical Therapeutic Chemical classification defined daily dose system. Utilisation was measured in terms of the defined daily dose (DDD) per 1000 older people per day (TOPD). RESULTS Overall, the utilisation of psychotropic medicines increased marginally by 0.42% between 2005 and 2019. The utilisation increased for antidepressants (72.42 to 75.21 DDD/TOPD) and antipsychotics (6.06-19.04 DDD/TOPD). In contrast, the utilisation of hypnotics and sedatives (53.74-38.90 DDD/TOPD) and anxiolytics decreased (10.20-9.87 DDD/TOPD). The utilisation of atypical antipsychotics increased (4.06-18.72 DDD/TOPD), with the highest percentage change in DDD/TOPD contributed by olanzapine (520.6 %). In comparison, utilisation of typical antipsychotics was relatively stable (2.00-2.06 DDD/TOPD). The utilisation of venlafaxine increased remarkably by 5.7 times between 2005 and 2019. The utilisation of zopiclone was far greater than that of other hypnotics in 2019. CONCLUSIONS There was only a marginal increase in psychotropic medicines utilisation from 2005 to 2019 in older adults in New Zealand. There was a five-fold increase in the utilisation of antipsychotic medicines. Continued monitoring of psychotropic medicine utilisation will be of interest to understand the utilisation of antidepressants and antipsychotic medicines during the coronavirus disease 2019 pandemic year.

Pharmacoepidemiol Drug Saf 2020; 29:692-700. [PMID: 32301237 DOI: 10.1002/pds.5007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 03/09/2020] [Accepted: 03/29/2020] [Indexed: 01/31/2023]
Abstract
PURPOSE The purpose of this study was to examine the incidence of Parkinsonism in new users of second-generation antipsychotics (SGAs) in older adults (≥65 years). In the secondary analyses, we examined the risk of Parkinsonism by type and dose of SGA and conducted age-sex interactions. METHOD This population-based study included older adults who had a new-onset diagnosis of Parkinsonism and who started taking olanzapine, risperidone or quetiapine between 1 January 2005, and 30 December 2016. The Cox proportional hazard (COXPH) model with inverse probability treatment weighted (IPTW) covariates was used to evaluate the risk of new-onset Parkinsonism associated with SGAs, using quetiapine as the reference. We used the Generalized Propensity Score method to evaluate the dose-response risk of Parkinsonism associated with SGAs. RESULTS After IPTW adjustment for covariates, the COXPH model showed that compared to quetiapine, the use of olanzapine and risperidone were associated with an increased risk of Parkinsonism. The IPTW-hazard ratios are 1.76 (95% confidence interval 1.57-1.97) and 1.31 (95%CI 1.16-1.49), respectively. The dose-response risk of Parkinsonism was highest for olanzapine with a hazard ratio of 1.69 (95%CI 1.40-2.05) and the least for quetiapine with a hazard ratio of 1.22 (95%CI 1.14-1.31). The risk of Parkinsonism in the 65 to 74-year age group was higher for both sexes with risperidone compared to olanzapine, but the risk increased with olanzapine for both sexes in the 85+ age group. CONCLUSION The study found that the risk of new-onset Parkinsonism in older adults is 31% and 76% higher with risperidone and olanzapine respectively compared to quetiapine.

Abstract
Despite growing concerns for the mental health of the older generation most studies focus on mental health care for younger people and there is a lack of knowledge about helpful treatment approaches and models of care for older people. Therefore, the purpose of this review was to answer the question what health care approaches are most helpful for older people experiencing mental health problems. Databases from 2000 to July 2017 were searched with focus on outcome studies, experts' opinions and treatment descriptions. Critical interpretive synthesis was used to analyse and interpret the findings. Four main models of care were found: the medical-psychiatric model which mostly focuses on antipsychotic medication for the treatment of symptoms. Psychotherapeutic and social interventions take into consideration the psychosocial perspectives of mental health problems, but little research has been done on their lasting effect. Research indicates that psychotherapy needs to be adapted to the special needs of older people. Few old people have access to psychotherapy which limits its usefulness. Holistic or integrated models of health care have emerged in recent years. These models focus on both physical and psychosocial well-being and have shown promising outcomes. To reduce antipsychotic medication older people need to be given better access to psychotherapy and social interventions. This presupposes training health care professionals in such treatment methods. The holistic models need to be developed and studied further and given high priority in health care policy.

Associations between the use of specific psychotropic drugs and all-cause mortality among older adults in Germany: Results of the mortality follow-up of the German National Health Interview and Examination Survey 1998. PLoS One 2019; 14:e0210695. [PMID: 30640945 PMCID: PMC6331145 DOI: 10.1371/journal.pone.0210695] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2018] [Accepted: 01/01/2019] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Use of psychotropic drugs is common among older adults. Population-based studies on the associations of psychotropic drug use with mortality are sparse. OBJECTIVES To investigate the associations between the use of specific psychotropic drug groups (opioids, antipsychotics, antidepressants and benzodiazepines) and all-cause mortality among community-dwelling older adults in Germany. METHODS Participants of the German National Health Interview and Examination Survey 1998 were followed up for mortality from 1997 to 2011. Persons aged 60-79 years with complete data on psychotropic drug use at baseline and on mortality follow-up were considered as study population (N = 1,563). Associations between the use of opioids, antipsychotics, antidepressants and benzodiazepines and all-cause mortality were examined by Cox proportional hazards models adjusted for sociodemographics (sex, age, community size, region, socioeconomic status), life style (smoking, sports, risky alcohol drinking) and health conditions (obesity, disability, history of cardiovascular diseases, diabetes, hyperlipidemia, hypertension, any cancers, any mental disorders) at baseline. RESULTS After a median follow-up of 11.4 years, 21, 18, 23 and 26 deaths were documented among those who used at baseline opioids (n = 39), antipsychotics (n = 30), antidepressants (n = 53) and benzodiazepines (n = 54) with an unadjusted mortality rate (MR) of 57.7, 59.1, 44.6 and 53.7 per 1000 person-years, respectively. Meanwhile, 400 deaths were documented among 1,406 nonusers of any of the above mentioned psychotropic drugs with a MR of 26.7 per 1000 person-years. The age and sex adjusted mortality rate ratios in comparison with nonusers were 2.20 (95% confidence intervals 1.42-3.41), 1.66(1.03-2.70), 1.56(1.06-2.28), and 1.57(1.07-2.31) for the use of opioids, antipsychotics, antidepressants and benzodiazepines, respectively. In the fully adjusted Cox models, use of opioids (hazardous ratio 2.04, 95% confidence intervals 1.07-3.89), antipsychotics (2.15, 1.11-4.15) and benzodiazepines (1.76, 1.09-2.82), but not antidepressants, were significantly associated with an increased risk of mortality. CONCLUSIONS Use of opioids, antipsychotics, benzodiazepines is significantly associated with an increased risk of all-cause mortality among community-dwelling older adults in Germany. Clinicians should be careful in prescribing these psychotropic drugs to older adults while patients already under psychotropic therapy should well balance the risks and benefits of drug use. Further studies with a larger sample size and information on specific indications for psychotropic drug use and mental comorbidities are required to confirm the findings of the present study.

Abstract
IMPORTANCE Medication review has been proposed to achieve improved use of psychotropic drugs, but benefits have not been confirmed. OBJECTIVE To synthesize evidence for focused psychotropic medication review in medication optimization. DATA SOURCES Medline, PsycINFO, EMBASE, and CINAHL Plus were searched from inception to February 2018 using the index terms "drug utilization review" and "psychotropic drugs" and synonyms. Additional articles were retrieved using citation tracking and reference checking. STUDY SELECTION Full-length, peer-reviewed articles that reported focused psychotropic medication review were included. Inclusion was determined against prespecified criteria and assessed independently. DATA EXTRACTION AND SYNTHESIS Study quality was assessed using National Institutes for Health appraisal tools and informed a structured synthesis of results. Meta-analysis using a random effects model was conducted. MAIN OUTCOMES AND MEASURES Change in the number or dosage of psychotropic medications, change in clinical parameters, change in patient-reported outcomes, and economic data were collected. RESULTS A total of 26 studies met the inclusion criteria. Four studies were randomized clinical trials (n = 712 participants), while the remainder were before-after studies (n = 7844 participants). Most studies were conducted in elderly individuals, people with dementia, and adults with intellectual disability. Focused psychotropic medication review is a complex intervention; the professional(s) involved, target drug, degree of integration with usual care, and participant involvement varied greatly among the studies. Meta-analysis included 3 studies (n = 652 participants). Psychotropic medication review was associated with a reduction in prescribing of psychotropic drugs compared with control (pooled odds ratio, 0.24; 95% CI, 0.14-0.39) in elderly participants with cognitive impairment living in nursing homes. Before-after studies consistently reported a change in psychotropic drug prescribing after medication review, regardless of the population. Studies that reported the effects of psychotropic medication review on clinical outcomes failed to demonstrate benefit. Economic implications of focused psychotropic medication review were not adequately assessed. The quality of evidence is poor and studies are at risk of bias. CONCLUSIONS AND RELEVANCE Focused psychotropic medication review was associated with a reduction in prescribing of psychotropic drugs, but has not been shown to improve clinical outcomes or to provide economic benefit. More robust evidence is needed before programs of focused psychotropic medication review can be recommended as part of routine care for any patient group.

International trends in antipsychotic use: A study in 16 countries, 2005-2014. Eur Neuropsychopharmacol 2017; 27:1064-1076. [PMID: 28755801 DOI: 10.1016/j.euroneuro.2017.07.001] [Citation(s) in RCA: 168] [Impact Index Per Article: 24.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2017] [Accepted: 07/05/2017] [Indexed: 11/23/2022]
Abstract
The objective of this study was to assess international trends in antipsychotic use, using a standardised methodology. A repeated cross-sectional design was applied to data extracts from the years 2005 to 2014 from 16 countries worldwide. During the study period, the overall prevalence of antipsychotic use increased in 10 of the 16 studied countries. In 2014, the overall prevalence of antipsychotic use was highest in Taiwan (78.2/1000 persons), and lowest in Colombia (3.2/1000). In children and adolescents (0-19 years), antipsychotic use ranged from 0.5/1000 (Lithuania) to 30.8/1000 (Taiwan). In adults (20-64 years), the range was 2.8/1000 (Colombia) to 78.9/1000 (publicly insured US population), and in older adults (65+ years), antipsychotic use ranged from 19.0/1000 (Colombia) to 149.0/1000 (Taiwan). Atypical antipsychotic use increased in all populations (range of atypical/typical ratio: 0.7 (Taiwan) to 6.1 (New Zealand, Australia)). Quetiapine, risperidone, and olanzapine were most frequently prescribed. Prevalence and patterns of antipsychotic use varied markedly between countries. In the majority of populations, antipsychotic utilisation and especially the use of atypical antipsychotics increased over time. The high rates of antipsychotic prescriptions in older adults and in youths in some countries merit further investigation and systematic pharmacoepidemiologic monitoring.

Abstract
OBJECTIVE There is some evidence that clozapine is significantly underutilised. Also, clozapine use is thought to vary by country, but so far no international study has assessed trends in clozapine prescribing. Therefore, this study aimed to assess clozapine use trends on an international scale, using standardised criteria for data analysis. METHOD A repeated cross-sectional design was applied to data extracts (2005-2014) from 17 countries worldwide. RESULTS In 2014, overall clozapine use prevalence was greatest in Finland (189.2/100 000 persons) and in New Zealand (116.3/100 000), and lowest in the Japanese cohort (0.6/100 000), and in the privately insured US cohort (14.0/100 000). From 2005 to 2014, clozapine use increased in almost all studied countries (relative increase: 7.8-197.2%). In most countries, clozapine use was highest in 40-59-year-olds (range: 0.6/100 000 (Japan) to 344.8/100 000 (Finland)). In youths (10-19 years), clozapine use was highest in Finland (24.7/100 000) and in the publicly insured US cohort (15.5/100 000). CONCLUSION While clozapine use has increased in most studied countries over recent years, clozapine is still underutilised in many countries, with clozapine utilisation patterns differing significantly between countries. Future research should address the implementation of interventions designed to facilitate increased clozapine utilisation.

Abstract
OBJECTIVE Treatment guidelines published world-wide have highlighted concerns of increased metabolic risks associated with second-generation antipsychotics (SGAs). The aim of the study was to evaluate blood glucose monitoring rates for SGA new users in older people aged 65 years and above during the study period 2006-2012, and investigate the pre-post 2007 Best Practice Advocacy Centre's (bpacnz) glucose monitoring recommendation in New Zealand. METHODS The study was a population-based retrospective cohort of SGA new users (365days without pre-exposure to antipsychotics). Pharmaceutical collections data were extracted and used to identify older people dispensed SGAs and linked to the National Minimum Dataset and Laboratory Claims collection. WHO Methodology's Anatomical Therapeutic Chemical method's classification was used to characterise the SGAs dispensed. RESULTS Of the 25,603 new users dispensed SGAs, 63.5% received glycaemic control monitoring at least once during the study period. Of these, only 20.1% were monitored at baseline, 38.7% were monitored for glycaemic control within the first 90 days. Glycaemic control monitoring within the first 180days increased to more than half (57.5%) of the SGA new users. Proportion of individuals monitored were independent (χ2=6.1; P=0.4) of pre-post bpacnz recommendation. CONCLUSIONS Blood glucose monitoring was underutilized in new SGA users. No significant improvement in glycaemic control monitoring was observed after the 2007 bpacnz consensus statement release at baseline, 90days and at 180 days. Prescribers must be cautioned about the metabolic risks posed by SGAs and recommend glycaemic control monitoring.

Abstract
AIM To examine psychotropic drug utilisation in older people in New Zealand by age, sex, health board domicile and deprivation status. METHODS A repeated cross-sectional analysis of population-based drug utilisation data stratified by age, sex, ethnicity, health board and deprivation status was conducted from 2005 to 2013. RESULTS Psychotropic utilisation increased between 2005 and 2013 (ranging from 7.0 to 74.0%) across all the health boards. In people aged 85 years and above, the hypnotic and sedative prevalence ratio compared to the 65- to 69-year age group was 1.45 (95% CI 1.44, 1.46). Between 2005 and 2013, the antidepressants prevalence ratio increased (1.27 (95% CI 1.22, 1.33)) relative to anxiolytics. CONCLUSIONS Overall psychotropic drug utilisation increased over time. Despite safety concerns, hypnotic and sedative utilisation increased in the oldest vulnerable group. Shifts from anxiolytics to antidepressants in some health boards were consistent with guidelines for extended indications of antidepressant drug use.

Abstract
INTRODUCTION Antipsychotic medicines are used regularly or when required in residential aged care facilities to treat symptoms of dementia, but have been associated with several adverse effects. AIM The aim of this study was to examine 'quality use' of antipsychotic medicines in residential aged care facilities in New Zealand, by surveying nurse managers. METHODS A cross-sectional survey was mailed to 318 nurse managers working in a nationally representative sample of aged care facilities. A purpose-developed, pre-tested, 22-item structured questionnaire was used to explore practice related to the quality use of antipsychotic medicines. RESULTS Overall, 31.4% of nurse managers responded to the survey. They mostly (88%) had ≥ 1 year's relevant work experience and 83% of facilities provided care for those within the range of 21 to 100 residents. Respondents reported that staff education on dementia management occurred early in employment. Two-thirds of participants reported non-pharmacological interventions were commonly used for managing challenging behaviours, while less than half (45%) cited administering antipsychotic medicine. Respondents reported 'managing behavioural symptoms' (81%) as one of the main indications for antipsychotic use. Frequently identified adverse effects of antipsychotic medicines were drowsiness or sedation (64%) and falls (61%). Over 90% reported general practitioners reviewed antipsychotic use with respect to residents' target behaviour 3-monthly, and two-thirds used an assessment tool to appraise residents' behaviour. DISCUSSION Staff education on dementia management soon after employment and resident 3-monthly antipsychotic medicine reviews were positive findings. However, a wider use of behavioural assessment tools might improve the care of residents with dementia and the quality use of antipsychotic medicines.

Abstract
To examine and characterize overall donepezil and concomitant utilization with β-blockers, yearly, in older New Zealanders. Deidentified data from the Pharmaceutical claims database and the National Minimum Dataset were obtained for 2011 to 2013 from the Ministry of Health. Population-level data were extracted for donepezil and β-blockers utilization, measured by defined daily dose (DDD) per thousand older people per day (TOPD). Donepezil utilization increased from 5.2 to 8.2 DDD/TOPD between 2011 and 2013. In 2011, the number of prevalent users was 4634, the mean age was 79.4±6.6 years and 57.5% were women. Highest use by age for donepezil was in those aged 85 years or older (2.3 DDD/TOPD), followed by those aged 80-84 years (2.2 DDD/TOPD). The mean utilization volumes were significantly lower for donepezil 5 mg (Student t-test=9.86; P<0.05) and 10 mg (10.90; P<0.05) in the 65- to 69-year age group compared with the 80- to 84-year age group, whereas the proportion of concomitant utilization of donepezil with β-blockers decreased (17.9% to 5.1%). Donepezil utilization in DDD/TOPD increased by three-fifths between 2011 and 2013. Prescribers appear to be aware of the potential risk of bradycardia with the concomitant use of donepezil and β-blockers.

Abstract
Background Donepezil is indicated for the management of mild to moderate dementia, particularly in Alzheimer's disease. Several studies have described low adherence rates with donepezil. Aim To examine and measure donepezil adherence, persistence and time to first discontinuation in older New Zealanders. Methods An inception cohort of 1,999 new users of donepezil, aged 65 years or older, were identified from the Pharmaceutical Collections and National Minimum Dataset from 1 November 2010 to 31 December 2013. Kaplan-Meier curves and Cox regression analysis were used to estimate the cumulative probability and risk of time to first discontinuation of donepezil therapy. Results The mean age of the cohort was 79.5 ± 6.4 years and included 42.7% females. Adherence was high (89.0%), while the proportion of donepezil dispensings (81.0-32.5%) declined between 6 and 36 months. Persistence between the 1st and 6th dispensing visit decreased by 19.0%, and 11.0% of the total cohort had a gap of 31 days or more. The adjusted risk of time to first discontinuation in the non-adherent group was 2.2 times (95% CI 1.9-2.6) that of the adherent group. Conclusions The non-adherent new donepezil users, on average, discontinued faster than the adherent group. Time to first discontinuation in this study was higher compared to discontinuation rates observed in clinical trials.

Abstract
Background Identifying potentially inappropriate medicines (PIMs) leading to adverse drug events may reduce the risk of morbidity and mortality in older people. Objective The aim of this study was to examine the relationship between exposure to PIMs and risk of Fall-related hospitalisations (FRH) and frequency of primary care visits in older New Zealanders. Methods Pharmaceutical collections (2011), diagnostic (2007–2011) and events (2012) information derived from the National Minimum Datasets were used to extract demographics, medication and diagnostic information for 537,387 individuals aged ≥65 years. Prescription and diagnostic information were matched through unique National Health Index numbers. The updated Beers 2012 criteria were used to identify PIMs. Polypharmacy was defined as five or more medicines dispensed concurrently for ≥90 days. Results Individuals exposed to one or more PIMs had an increased risk of FRH with an incidence rate ratio (IRR) of 1.45 (95 % confidence interval [CI] 1.37–1.52) and a greater number of primary care visits (IRR 1.15; 95 % CI 1.15–1.16). Individuals exposed to polypharmacy had an IRR of 1.41 (95 % CI 1.33–1.50) for FRH and an IRR of 1.14 (95 % CI 1.13–1.15) for primary care visits. Conclusion PIMs identified by the 2012 Beers criteria showed an increased risk of FRH and a greater number of primary care visits. Age ≥85 years and female sex were identified as significant predictors of FRH and primary care visits.
