Psychiatry Res 2024; 338:115974. [PMID: 38833938 DOI: 10.1016/j.psychres.2024.115974] [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: 02/01/2024] [Revised: 05/13/2024] [Accepted: 05/22/2024] [Indexed: 06/06/2024]
Abstract
An association between psychiatric medications and falls and fractures in people taking them has been demonstrated, but which class or medication leads to the greatest risk of falls or fractures should be further investigated. The aim of this study was to compare and rank the magnitude of risk of falls and fractures due to different psychiatric medications. Eight databases were searched for this meta-analysis and evaluated using a frequency-based network meta-analysis. The results included a total of 28 papers with 14 medications from 5 major classes, involving 3,467,314 patients. The results showed that atypical antipsychotics were the class of medications with the highest risk of falls, and typical antipsychotics were the class of medications with the highest risk of resulting in fractures. Quetiapine ranked first in the category of 13 medications associated with risk of falls, and class Z drugs ranked first in the category of 6 medications associated with risk of fractures. The available evidence suggests that atypical antipsychotics and typical antipsychotics may be the drugs with the highest risk of falls and fractures, respectively. Quetiapine may be the medication with the highest risk of falls, and class Z drugs may be the medication with the highest risk of fractures.

[PMID: 37926010 DOI: 10.1016/j.smrv.2023.101866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 09/25/2023] [Accepted: 10/08/2023] [Indexed: 11/07/2023]
Abstract
We reviewed and meta-analyzed 20 observational studies to examine the relationship between sedative-hypnotic use and osteoporotic fractures. We searched PubMed, Embase, APA PsycINFO, and Web of Science™ for studies that used cohort, case-control, case-crossover, and self-controlled case series designs. We further assessed the quality of each study and performed meta-analyses of association estimates, e.g., odds ratios (ORs). The analysis included 6,084,083 participants and found a slight association between the use of sedative-hypnotics and osteoporotic fractures, with differing strength of associations between different classes of drugs and greater sedative-hypnotics exposure. The pooled estimates ORs for case-control studies were 1.33 (95% CI 0.98-1.80) with benzodiazepines (BZD) and any fractures, 1.32 (95% CI 1.05-1.66) with BZDs and hip fractures, and case-crossover studies were 1.15 (95% CI 0.95-1.41) with BZDs and any fractures, 1.41 (95% CI 1.08-1.85) with Z-drugs and any fractures. The study suggests that more research is needed to aid medical professionals in balancing this potential risk of osteoporotic fractures associated with sedative-hypnotic use against other reported adverse events and anticipated therapy outcomes.

Evaluating the use of methods to mitigate bias from non-transient medications in the case-crossover design: A systematic review. Pharmacoepidemiol Drug Saf 2023; 32:939-950. [PMID: 37283212 DOI: 10.1002/pds.5649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 03/30/2023] [Accepted: 06/02/2023] [Indexed: 06/08/2023]
Abstract
PURPOSE The case-crossover design is a self-controlled study design used to compare exposure immediately preceding an event occurrence with exposure in earlier control periods. The design is most suitable for transient exposures in order to avoid biases that can be problematic when using the case-crossover design for non-transient (i.e., chronic) exposures. Our goal was to conduct a systematic review of case-crossover studies and its variants (case-time-control and case-case-time-control) in order to compare design and analysis choices by medication type. METHODS We conducted a systematic search to identify recent case-crossover, case-time-control, and case-case-time-control studies focused on medication exposures. Articles indexed in MEDLINE and EMBASE using these study designs that were published between January 2015 and December 2021 in the English language were identified. Reviews, methodological studies, commentaries, articles without medications as the exposure of interest, and articles with no available full text were excluded. Study characteristics including study design, outcome, risk window, control window, reporting of discordant pairs, and inclusion of sensitivity analyses were summarized overall and by medication type. We further evaluated the implementation of recommended methods to account for biases introduced by non-transient exposures among articles that used the case-crossover design on a non-transient exposure. RESULTS Of the 2036 articles initially identified, 114 articles were included. The case-crossover was the most common study design (88%), followed by the case-time-control (17%), and case-case-time-control (3%). Fifty-three percent of the articles included only transient medications, 35% included only non-transient medications, and 12% included both. Across years, the proportion of case-crossover articles evaluating a non-transient medication ranged from 30% in 2018 to 69% in 2017. We found that 41% of the articles that evaluated a non-transient medication did not apply any of the recommended methods to account for biases and more than half of which were conducted by authors with no previous publication history of case-crossover studies. CONCLUSION Using the case-crossover design to evaluate a non-transient medication remains common in pharmacoepidemiology. Researchers should apply appropriate design and analysis choices when opting to use a case-crossover design with non-transient medication exposures.

Association between the Use of Suvorexant and Hip Fracture in Older Adults in Japan Using a Nationwide Administrative Claims Database: A Matched Case-Control Study. Drugs Aging 2023; 40:439-447. [PMID: 37121956 DOI: 10.1007/s40266-023-01033-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/11/2023] [Indexed: 05/02/2023]
Abstract
BACKGROUND AND OBJECTIVE The use of benzodiazepines and nonbenzodiazepines increases the risk for hip fracture, but the effect of suvorexant, an orexin receptor antagonist, is not clear. The objective of this study was to investigate the association between suvorexant use and hip fractures in older adults. METHODS A case-control study was conducted using real-world data (RWD) from Medical Data Vision Co., Ltd. with patients hospitalized between January 2019 and December 2020. Patients were aged 65-84 years and had been prescribed suvorexant at least once. Patients with hip fracture (cases) and those without (controls) were identified by matching up to 1:4 for sex, age (± 2 years), and hospital size category. Suvorexant exposure was identified the day before hospitalization. Hip fracture risk associated with suvorexant was presented as adjusted odds ratios (aOR) with 95% confidence intervals (CI) using conditional logistic regression analysis. RESULTS Matching identified 389 cases and 1509 controls. The risk of hip fracture was not increased in patients treated with suvorexant [aOR: 0.86, 95% confidence interval (CI) 0.61-1.20]. Additionally, concomitant use of suvorexant with other hypnotics did not increase the risk. Benzodiazepines (1.01, 0.46-2.22), nonbenzodiazepines (1.16, 0.57-2.34), and melatonin (1.80, 0.82-3.94) were combined with suvorexant. The risk was increased for the use of benzodiazepine without suvorexant (1.88, 1.10-3.21). CONCLUSIONS Using RWD in Japanese older adults, we showed that sleep therapy with suvorexant was not associated with an increased risk of hip fracture. The results provide evidence-based drug safety information for the selection of hypnotics for sleep disorders, which increase with age.

Abstract
BACKGROUND An increased risk of fracture has been reported in older adults taking hypnotics. However, few studies have reported the comparative safety of hypnotics with different mechanisms of action. We examined the risk of fracture in older adults initiating suvorexant compared to those initiating Z-drugs. METHODS We conducted a retrospective cohort study using a claims database within a longevity improvement and fair evidence (LIFE) study in Japan (1.5 million beneficiaries). People aged ≥65 years were included in this study. Exposure was defined as the initiation of either suvorexant or Z-drugs (eszopiclone, zolpidem, or zopiclone). The evaluated outcomes were hip fracture and all-cause fracture requiring hospitalization. We used inverse probability of treatment weights to adjust for confounding and followed the incidence of the outcome for three different periods: 30, 90, and 365 days. Cox proportional hazards models were fitted to the weighted population to estimate hazard ratios (HRs). Sensitivity analyses were performed with narrowed outcome definitions and inverse probability of censoring weights. RESULTS We identified 16,148 suvorexant new users and 54,327 Z-drugs new users. During the 30-day follow-up, 21 (16.6 events per 1000 person-years) and 53 hip fractures (12.2 events per 1000 person-years) were identified among suvorexant and Z-drugs new users, respectively (HR: 1.01, 95% confidence interval [CI]: 0.58-1.76). The analysis for all-cause fracture showed an HR of 1.03 (95% CI: 0.78-1.36). Extended follow-up (90 and 365 days) showed similar results for both outcomes. Sensitivity analyses showed consistent results except for an increased risk of all-cause fracture requiring surgery (HR: 1.41, 95% CI: 0.87-2.29) during the 30-day follow-up. CONCLUSIONS This is the first study to show that suvorexant has a generally comparable risk of fracture as compared to Z-drugs. Further research is needed to investigate the potential short-term increased risk of all-cause fracture requiring surgery among suvorexant initiators.

Prescription of Silexan Is Associated with Less Frequent General Practitioner Repeat Consultations Due to Disturbed Sleep Compared to Benzodiazepine Receptor Agonists: A Retrospective Database Analysis. Healthcare (Basel) 2022; 11:healthcare11010077. [PMID: 36611537 PMCID: PMC9819079 DOI: 10.3390/healthcare11010077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 12/22/2022] [Accepted: 12/23/2022] [Indexed: 12/29/2022] Open
Abstract
The aim of the present study was to analyze the association between the prescription of Silexan and the recurrence of general practitioner (GP) repeat consultations because of disturbed sleep versus benzodiazepine receptor agonists including zolpidem, zopiclone, and zaleplon (Z-drugs). This retrospective cohort study was based on data from the IQVIA Disease Analyzer (DA) database. The study included adult patients treated by 1284 GPs in Germany with a documented sleep disorder and their first prescription of Silexan or Z-drug (prescription between January 2010 and October 2020). The recurrence of seeking medical advice because of sleep disorders in the 15-365 days after the first prescription was evaluated. Multivariate regression models were used, adjusted for age, sex, insurance status, and defined co-diagnoses. Data were available for 95,320 (Silexan: 5204; Z-Drug: 90,526) patients. In total, 15.6% of the Silexan patients and 28.6% of the Z-drug patients had a further documented GP consultation because of a sleep disorder. Silexan prescription was associated with significantly lower odds of recurrent sleep disorder diagnosis in the 15-365 days after the index date (Odds Ratio (OR): 0.56; 95% confidence intervals (CI): 0.51-0.60), although mental burden levels appeared higher in this group. Our study shows that the prescription of Silexan to adult patients consulting GPs for disturbed sleep results in less frequent repeat consultations than Z-drugs. This may support Silexan's role as an efficacious, self-enabling, well-tolerated, and sustained treatment option. Because Silexan is a proven anxiolytic, its impact in improving undiagnosed anxiety disorders may have had a lasting effect for certain patients.

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.

Abstract
BACKGROUND Falls and falls-related injuries are common among older adults. Injuries in older adults lead to poor outcomes and lower quality of life. The objective of our study was to identify factors associated with fall-related injuries among home care clients in New Zealand. METHODS The study cohort consisted of 75,484 community-dwelling people aged 65 years or older who underwent an interRAI home care assessment between June 2012 and June 2018 in New Zealand. The injuries included for analysis were fracture of the distal radius, hip fracture, pelvic fracture, proximal humerus fracture, subarachnoid haemorrhage, traumatic subdural haematoma, and vertebral fracture. Unadjusted and adjusted competing risk regression models were used to identify factors associated with fall-related injuries. RESULTS A total of 7414 (9.8%) people sustained a falls-related injury over the 6-year period, and most injuries sustained were hip fractures (4735 63.9%). The rate of injurious falls was 47 per 1000 person-years. The factors associated with injury were female sex, older age, living alone, Parkinson's disease, stroke/CVA, falls, unsteady gait, tobacco use, and being underweight. Cancer, dyspnoea, high BMI, and a decrease in the amount of food or fluid usually consumed, were associated with a reduced risk of sustaining an injury. After censoring hip fractures the risks associated with other types of injury were sex, age, previous falls, dyspnoea, tobacco use, and BMI. CONCLUSIONS While it is important to reduce the risk of falls, it is especially important to reduce the risk of falls-related injuries. Knowledge of risk factors associated with these types of injuries can help to develop focused intervention programmes and development of a predictive model to identify those who would benefit from intervention programmes.

Effects of anticholinergic and sedative medication use on fractures: A self-controlled design study. J Am Geriatr Soc 2021; 69:3212-3224. [PMID: 34291817 PMCID: PMC8595585 DOI: 10.1111/jgs.17377] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 05/20/2021] [Accepted: 06/15/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND/OBJECTIVES Unintentional falls are a leading cause of injury for older adults, and evidence is needed to understand modifiable risk factors. We evaluated 1-year fall-related fracture risk and whether dispensing of medications with anticholinergic/sedating properties is temporally associated with an increased odds of these fractures. DESIGN A retrospective cohort study with nested self-controlled analyses conducted between January 1, 2014, and December 31, 2016. SETTING Twenty percent nationwide, random sample of US Medicare beneficiaries. PARTICIPANTS New users of medications with anticholinergic/sedating properties who were 66+ years old and had Medicare Parts A, B, and D coverage but no claims for medications with anticholinergic/sedating properties in the year before initiation were eligible. MEASUREMENTS We followed new users of medications with anticholinergic/sedating properties until first non-vertebral, fall-related fracture (primary outcome), Medicare disenrollment, death, or end of study data. We estimated the 1-year risk with corresponding 95% confidence intervals (CIs) of first fracture after new use. We applied the self-controlled case-crossover and case-time-control designs to estimate odds ratios (ORs) and 95% CIs by comparing anticholinergic and/or sedating medication exposure (any vs. none) during a 14-day hazard period preceding the fracture to exposure to these medications during an earlier 14-day control period. RESULTS A total of 1,097,989 Medicare beneficiaries initiated medications with anticholinergic/sedating properties in the study period. The 1-year cumulative incidence of fall-related fracture, accounting for death as a competing risk, was 5.0% (95% CI: 5.0%-5.0%). Using the case-crossover design (n = 41,889), the adjusted OR for the association between anticholinergic/sedating medications and fractures was 1.03 (95% CI: 0.99, 1.08). Accounting for the noted temporal trend using the case-time-control design (n = 209,395), the adjusted OR was 1.60 (95% CI: 1.52, 1.69). CONCLUSION Use of anticholinergic/sedating medication was temporally associated with an increased odds of fall-related fractures. Patients and their healthcare providers should consider pharmacologic and non-pharmacologic treatments for the target condition that are safer.

Abstract
OBJECTIVES We aim to study the effects of the prescription of benzodiazepines and antidepressants on cognitive and functional decline in older adults living with Alzheimer's disease (AD) and Lewy body dementia (LBD) over a 5-year follow-up. METHODS This is a longitudinal analysis of a Norwegian cohort study entitled "The Dementia Study of Western Norway" (DemVest). We included 196 patients newly diagnosed with AD (n = 111) and LBD (n = 85), followed annually for 5 years. Three prescription groups were defined: only benzodiazepines (BZD), only antidepressants (ADep), and the combination of benzodiazepines and antidepressants (BZD-ADep). Linear mixed-effects models were conducted to analyze the effect of the defined groups on the outcomes. The outcomes were functional decline, measured by the Rapid Disability Rating Scale-2, and cognition measured with the Mini-Mental State Examination. RESULTS Prescription of the combination of benzodiazepines and antidepressants in LBD was associated with faster functional decline. In AD, the prescription of BZD and BZD-ADep was associated with greater functional deterioration. ADep alone did not show positive or negative significant associations with the studied outcomes. CONCLUSIONS BZD and especially the combination of BZD and ADep are associated with functional decline in AD and LBD and should be used cautiously.

Risk factors for hip fracture in New Zealand older adults seeking home care services: a national population cross-sectional study. BMC Geriatr 2019; 19:93. [PMID: 30909862 PMCID: PMC6434861 DOI: 10.1186/s12877-019-1107-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2018] [Accepted: 03/18/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Hip fractures are a common injury in older people. Many studies worldwide have identified various risk factors for hip fracture. However, risk factors for hip fracture have not been studied extensively in New Zealand. The interRAI home care assessment consists of 236 health questions and some of these may be related to hip fracture risk. METHODS The cohort consisted of 45,046 home care clients aged 65 years and older, in New Zealand. Assessments ranged from September 2012 to October 2015. Hip fracture diagnosis was identified by linking ICD (International Classification of Diseases) codes from hospital admissions data (September 2012 to December 2015) to the interRAI home care data. Unadjusted and adjusted competing risk regressions, using the Fine and Gray method were used to identify risk factors for hip fracture. Mortality was the competing event. RESULTS The cohort consisted of 61% female with a mean age of 82.7 years. A total of 3010 (6.7%) of the cohort sustained a hip fracture after assessment. After adjusting for sociodemographic and potentially confounding variables falls (SHR (Subhazard Ratio) = 1.17, 95% CI (Confidence interval): 1.05-1.31), previous hip fracture (SHR = 4.16, 95% CI: 2.93-5.89), female gender (SHR = 1.38, 95% CI: 1.22-1.55), underweight (SHR = 1.67, 95% CI = 1.39-2.02), tobacco use (SHR = 1.56, 95% CI = 1.25-1.96), Parkinson's disease (SHR = 1.45, 95% CI: 1.14-1.84), and Wandering (SHR = 1.36, 95% CI: 1.07-1.72) were identified as risk factors for hip fracture. Shortness of breath (SHR = 0.80, 95% CI: 0.71-0.90), was identified as being protective against hip fracture risk. Males and females had different significant risk factors. CONCLUSIONS Risk factors for hip fracture similar to international work on risk factors for hip fracture, can be identified using the New Zealand version of the interRAI home care assessment.
