Project description:BackgroundWith rising worldwide population aging, the number of homebound individuals with multimorbidity is increasing. Improvement in the quality of home medical care (HMC), including medications, contributes to meeting older adults' preference for "aging in place" and securing healthcare resources.ObjectiveTo evaluate the changes in drug prescriptions, particularly potentially inappropriate medications (PIMs), among older adults receiving HMC in recent years, during which measures addressing inappropriate polypharmacy were implemented, including the introduction of clinical practice guidelines and medical fees for deprescribing.DesignA cross-sectional study.ParticipantsUsing data from the national claims database in Japan, this study included older adults aged ≥ 75 years who received HMC in October 2015 (N = 499,850) and October 2019 (N = 657,051).Main measuresNumber of drugs, prevalence of polypharmacy (≥ 5 regular drugs), major drug categories/classes, and PIMs according to Japanese guidelines were analyzed. Random effects logistic regression models were used to evaluate the differences in medications between 2015 and 2019, considering the correlation within individuals who contributed to the analysis in both years.Key resultsThe number of drugs remained unchanged from 2015 to 2019 (median: 6; interquartile range: 4, 9). The prevalence of polypharmacy also remained unchanged at 70.0% in both years (P = 0.93). However, the prescription of some drugs (e.g., direct oral anticoagulants, new types of hypnotics, acetaminophen, proton pump inhibitors, and β-blockers) increased, whereas others (e.g., warfarin, vasodilators, H2 blockers, acetylcholinesterase inhibitors, and benzodiazepines) decreased. Among the frequently prescribed PIMs, benzodiazepines/Z-drugs (25.6% in 2015 to 21.1% in 2019; adjusted odds ratio: 0.52) and H2 blockers (11.2 to 7.3%; 0.45) decreased, whereas diuretics (23.8 to 23.6%; 0.90) and antipsychotics (9.7 to 10.5%; 1.11) remained unchanged.ConclusionsWe observed some favorable changes but identified some continuous and new challenges. This study suggests that continued attention to medication optimization is required to achieve safe and effective HMC.

Project description:BackgroundLittle is known about the impact of cumulative attention-deficit/hyperactivity disorder (ADHD) medication use on the risk of type 2 diabetes (T2D).ObjectiveThe objective is to examine the association between cumulative use of ADHD medication and risk of incident T2D.MethodsA nested case-control study was conducted in a national cohort of individuals aged 18-70 years with incident ADHD (n=138 778) between 2007 and 2020 through Swedish registers. Individuals with incident T2D after ADHD were selected as cases (n=2355) and matched with up to five controls (n=11 681) on age at baseline, sex and birth year. Conditional logistic regression models examined the association between cumulative duration of ADHD medication use and T2D.FindingsCompared with no use, a decreased risk of T2D was observed for those on cumulative use of ADHD medications up to 3 years (ORs: 0<duration≤1 year, 0.79 (95% CI, 0.69 to 0.91); 1<duration≤3 years, 0.80 (95% CI, 0.69 to 0.92); duration>3 years, 0.97 (95% CI, 0.84 to 1.12)). When investigating medication types separately, methylphenidate showed results similar to main analyses, lisdexamfetamine showed no association with T2D, whereas long-term (>3 years) use of atomoxetine was associated with an increased risk of T2D (OR: 1.44 (95% CI, 1.01 to 2.04)).ConclusionCumulative use of ADHD medication does not increase the risk for T2D, with the exception of long-term use of atomoxetine.Clinical implicationsFindings suggest that clinicians should be aware of the potential risk of T2D associated with the cumulative use of atomoxetine among patients with ADHD; however, further replication is strongly needed.

Project description:BackgroundOlder adults requiring care often have multiple morbidities that lead to polypharmacy, including the use of potentially inappropriate medications (PIMs), leading to increased medical costs and adverse drug effects. We conducted a cross-sectional study to clarify the actual state of drug prescriptions and the background of polypharmacy and PIMs.MethodsUsing long-term care (LTC) and medical insurance claims data in the Ibaraki Prefecture from April 2018 to March 2019, we included individuals aged ≥ 65 who used LTC services. The number of drugs prescribed for ≥ 14 days and the number of PIMs were counted. A generalized linear model was used to analyze the association between the backgrounds of individuals and the number of drugs; logistic regression analysis was used for the presence of PIMs. PIMs were defined by STOPP-J and Beers Criteria.ResultsHerein, 67,531 older adults who received LTC services were included. The median number of total prescribed medications and PIMs was 7(IQR 5-9) and 1(IQR 0-1), respectively. The main PIMs were loop diuretics/aldosterone antagonists (STOPP-J), long-term use of proton pump inhibitors (Beers Criteria), benzodiazepines/similar hypnotics (STOPP-J and Beers Criteria), and nonsteroidal anti-inflammatory drugs (STOPP-J and Beers Criteria). Multivariate analysis revealed that the number of medications and presence of PIMs were significantly higher in patients with comorbidities and in those visiting multiple medical institutions. However, patients requiring care level ≥1, nursing home residents, users of short-stay service, and senior daycare were negatively associated with polypharmacy and PIMs.ConclusionsPolypharmacy and PIMs are frequently observed in older adults who require LTC. This was prominent among individuals with comorbidities and at multiple consulting institutions. Utilization of nursing care facilities may contribute to reducing polypharmacy and PIMs.

Project description:BackgroundThe use of medication for Attention-Deficit/Hyperactivity Disorder (ADHD) increased globally throughout the early 2000s. This study examine trends in prevalences and incidences of medication use in Norway from 2006 to 2022.MethodsData from the Norwegian Prescription Database were used to present one-year-prevalence and incidence rates of ADHD medication (ATC-group N06BA and C02AC02) for the overall population (ages 6-64) and within sex and age subgroups of children (ages 6-17) and adults (ages 18-64). Incident use was defined as the dispensing of medication, with no recorded use in the previous two calendar years.ResultsThe overall prevalence of ADHD medication use in 6- to 64-year-olds increased from 5.2 to 19.4 per 1000 in the period, most pronounced from 2020 and onwards. While males experienced a nearly threefold increase in use (from 7.3 to 20.6 per 1000), the use among females increased almost sixfold during the study period (from 3.0 to 18.1 per 1000). Consequently, the male-to-female prevalence-ratio decreased from 2.4 to 1. Children exhibited a higher prevalence of use compared to adults throughout the period, although the largest relative increase was observed in adults, particularly in female adults. In children the male-to-female ratio decreased from 3.2 to 2.0, primarily due to an increasing use in 13-17-year-old females. Among adults, prevalences were similar across most age groups, with the highest rates observed among those aged 18-24, where female use exceeded male use by the end of the period. The male-to-female prevalence-ratio in adults decreased from 1.6 to 0.9 during the period. Parallel to prevalent use, overall incident use increased from 1.4 to 5.0 per 1000 during the period, with the most pronounced increase occurring from 2020 and onwards. From this point, incident use among females aged 13-17, 18-24, and 25-34, exceeded that of males. The male-to-female incidence-ratio decreased from 1.8 to 0.9. The overall incidence to prevalence ratio remained similar throughout the period, being 0.27 in 2006 and 0.25 in 2022.ConclusionA sustained increase in the prevalence of ADHD medication use was observed, with the most pronounced rise occurring among females and adults from 2020 and onwards. By 2022, the overall gender disparity in ADHD medication use had diminished, which should be considered in the context of a steep increase in incident use among adolescent and young adult females starting from 2020.

Project description:Polypharmacy is a growing and major public health issue, particularly in the geriatric population. This study aimed to examine the association between polypharmacy and the risk of hospitalization and mortality. We included 3,007,620 elderly individuals aged ≥ 65 years who had at least one routinely-prescribed medication but had no prior hospitalization within a year. The primary exposures of interest were number of daily prescribed medications (1-2, 3-4, 5-6, 7-8, 9-10, and ≥ 11) and presence of polypharmacy (≥ 5 prescription drugs per day). The corresponding comparators were the lowest number of medications (1-2) and absence of polypharmacy. The study outcomes were hospitalization and all-cause death. The median age of participants was 72 years and 39.5% were men. Approximately, 46.6% of participants experienced polypharmacy. Over a median follow-up of 5.0 years, 2,028,062 (67.4%) hospitalizations and 459,076 (15.3%) all-cause deaths were observed. An incrementally higher number of daily prescribed medications was found to be associated with increasingly higher risk for hospitalization and mortality. These associations were consistent across subgroups of age, sex, residential area, and comorbidities. Furthermore, polypharmacy was associated with greater risk of hospitalization and death: adjusted HRs (95% CIs) were 1.18 (1.18-1.19) and 1.25 (1.24-1.25) in the overall and 1.16 (1.16-1.17) and 1.25 (1.24-1.25) in the matched cohorts, respectively. Hence, polypharmacy was associated with a higher risk of hospitalization and all-cause death among elderly individuals.

Project description:BackgroundPolypharmacy and potentially inappropriate medications (PIMs) are common among older adults with blood cancers, but their association with frailty and how to manage them optimally remain unclear.Patients and methodsFrom 2015 to 2019, patients aged ≥75 years presenting for initial oncology consult underwent screening geriatric assessment. Patients were determined to be robust, prefrail, or frail via deficit accumulation and phenotypic approaches. We quantified each patient's total number of medications and PIMs using the Anticholinergic Risk Scale (ARS) and a scale we generated using the NCCN Medications of Concern called the Geriatric Oncology Potentially Inappropriate Medications (GO-PIM) scale. We assessed cross-sectional associations of PIMs with frailty in multivariable regression models adjusting for age, gender, and comorbidity.ResultsOf 785 patients assessed, 603 (77%) were taking ≥5 medications and 421 (54%) were taking ≥8 medications; 201 (25%) were taking at least 1 PIM based on the ARS and 343 (44%) at least 1 PIM based on the GO-PIM scale. Among the 468 (60%) patients on active cancer treatment, taking ≥8 medications was associated with frailty (adjusted odds ratio [aOR], 2.82; 95% CI, 1.92-4.17). With each additional medication, the odds of being prefrail or frail increased 8% (aOR, 1.08; 95% CI, 1.04-1.12). With each 1-point increase on the ARS, the odds of being prefrail or frail increased 19% (aOR, 1.19; 95% CI, 1.03-1.39); with each additional PIM based on the GO-PIM scale, the odds increased 65% (aOR, 1.65; 95% CI, 1.34-2.04).ConclusionsPolypharmacy and PIMs are prevalent among older patients with blood cancers; taking ≥8 medications is strongly associated with frailty. These data suggest careful medication reconciliation for this population may be helpful, and deprescribing when possible is high-yield, especially for PIMs on the GO-PIM scale.

Project description:BackgroundAdhering to multiple medications as prescribed is challenging for older patients (aged ≥ 65 years) and a difficult behaviour to improve. Previous interventions designed to address this have been largely complex in nature but have shown limited effectiveness and have rarely used theory in their design. It has been recognised that theory ('a systematic way of understanding events or situations') can guide intervention development and help researchers better understand how complex adherence interventions work. This pilot study aims to test a novel community pharmacy-based intervention that has been systematically developed using the Theoretical Domains Framework (12-domain version) of behaviour change.MethodsAs part of a non-randomised pilot study, pharmacists in 12 community pharmacies across Northern Ireland (n = 6) and London, England (n = 6), will be trained to deliver the intervention to older patients who are prescribed ≥ 4 regular medicines and are non-adherent (self-reported). Ten patients will be recruited per pharmacy (n = 120) and offered up to four tailored one-to-one sessions, in the pharmacy or via telephone depending on their adherence, over a 3-4-month period. Guided by an electronic application (app) on iPads, the intervention content will be tailored to each patient's underlying reasons for non-adherence and mapped to the most appropriate solutions using established behaviour change techniques. This study will assess the feasibility of collecting data on the primary outcome of medication adherence (self-report and dispensing data) and secondary outcomes (health-related quality of life and unplanned hospitalisations). An embedded process evaluation will assess training fidelity for pharmacy staff, intervention fidelity, acceptability to patients and pharmacists and the intervention's mechanism of action. Process evaluation data will include audio-recordings of training workshops, intervention sessions, feedback interviews and patient surveys. Analysis will be largely descriptive.DiscussionUsing pre-defined progression criteria, the findings from this pilot study will guide the decision whether to proceed to a cluster randomised controlled trial to test the effectiveness of the S-MAP intervention in comparison to usual care in community pharmacies. The study will also explore how the intervention components may work to bring about change in older patients' adherence behaviour and guide further refinement of the intervention and study procedures.Trial registrationThis study is registered at ISRCTN: 10.1186/ISRCTN73831533.

Project description:IntroductionOlder adults are among the most vulnerable groups during the COVID-19 epidemic, contributing to a large proportion of COVID-19-related death. Medication review and reconciliation by pharmacist can help reduce the number of potentially inappropriate medications but these services were halted during COVID-19.AimTo assess the prevalence and factors associated with inappropriate medicine use among older populations with COVID-19.MethodsThis was a cross-sectional, retrospective analysis of medications among hospitalized older adults with COVID-19. Potentially inappropriate medication use was categorized using the Beer's and STOPP criteria.ResultsCombining both criteria, 181 (32.7%) of the 553 patients were identified to have used at least one or more potentially inappropriate medication. A marginally higher number of inappropriate medications was documented using the Beers 2019 criteria (151 PIM in 124 patients) compared to STOPP criteria (133 PIMS in 104 patients). The long-term use of proton pump inhibitors (n = 68; 12.3%) and drugs which increases the risk of postural hypotension were the most commonly reported PIM (n = 41; 7.4%). Potentially inappropriate medication use was associated with previous history of hospital admission in the past 12 months (Odds ratio [OR]: 2.27; 95% CI 1.29-3.99) and higher number of discharge medications.ConclusionsNearly, one in three older adults with COVID-19 had been prescribed a PIM, and the proportion of older adults with polypharmacy increased after discharge. This highlights the importance of having clinical pharmacist conducting medication reviews to identify PIMs and ensure medication appropriateness.

Project description:BackgroundPolypharmacy and potentially inappropriate medications (PIMs) are prevalent in older adults with cancer, but their associations with physical function are not often studied. This study examined the associations of polypharmacy and PIMs with physical function in older adults with cancer, and determined the optimal cutoff value for the number of medications most strongly associated with physical functional impairment.MethodsThis cross-sectional analysis used baseline data from a randomized study enrolling patients aged ≥70 years with advanced cancer starting a new systemic cancer treatment. We categorized PIM using 2015 American Geriatrics Society Beers Criteria. Three validated physical function measures were used to assess patient-reported impairments: activities of daily living (ADL) scale, instrumental activities of daily living (IADL) scale, and the Older Americans Resources and Services Physical Health (OARS PH) survey. Optimal cutoff value for number of medications was determined by the Youden index. Separate multivariate logistic regressions were then performed to examine associations of polypharmacy and PIMs with physical function measures.ResultsAmong 439 patients (mean age, 76.9 years), the Youden index identified ≥8 medications as the optimal cutoff value for polypharmacy; 43% were taking ≥8 medications and 62% were taking ≥1 PIMs. On multivariate analysis, taking ≥8 medications was associated with impairment in ADL (adjusted odds ratio [aOR], 1.64; 95% CI, 1.01-2.58) and OARS PH (aOR, 1.73; 95% CI, 1.01-2.98). PIMs were associated with impairments in IADL (aOR, 1.72; 95% CI, 1.09-2.73) and OARS PH (aOR, 1.97; 95% CI, 1.15-3.37). A cutoff of 5 medications was not associated with any of the physical function measures.ConclusionsPhysical function, an important component of outcomes for older adults with cancer, is cross-sectionally associated with polypharmacy (defined as ≥8 medications) and with PIMs. Future studies should evaluate the association of polypharmacy with functional outcomes in this population in a longitudinal fashion.

Project description:More than 1.5 million US adults use stimulants and other medications labeled for treatment of attention-deficit/hyperactivity disorder (ADHD). These agents can increase heart rate and blood pressure, raising concerns about their cardiovascular safety.To examine whether current use of medications prescribed primarily to treat ADHD is associated with increased risk of serious cardiovascular events in young and middle-aged adults.Retrospective, population-based cohort study using electronic health care records from 4 study sites (OptumInsight Epidemiology, Tennessee Medicaid, Kaiser Permanente California, and the HMO Research Network), starting in 1986 at 1 site and ending in 2005 at all sites, with additional covariate assessment using 2007 survey data. Participants were adults aged 25 through 64 years with dispensed prescriptions for methylphenidate, amphetamine, or atomoxetine at baseline. Each medication user (n = 150,359) was matched to 2 nonusers on study site, birth year, sex, and calendar year (443,198 total users and nonusers).Serious cardiovascular events, including myocardial infarction (MI), sudden cardiac death (SCD), or stroke, with comparison between current or new users and remote users to account for potential healthy-user bias.During 806,182 person-years of follow-up (median, 1.3 years per person), 1357 cases of MI, 296 cases of SCD, and 575 cases of stroke occurred. There were 107,322 person-years of current use (median, 0.33 years), with a crude incidence per 1000 person-years of 1.34 (95% CI, 1.14-1.57) for MI, 0.30 (95% CI, 0.20-0.42) for SCD, and 0.56 (95% CI, 0.43-0.72) for stroke. The multivariable-adjusted rate ratio (RR) of serious cardiovascular events for current use vs nonuse of ADHD medications was 0.83 (95% CI, 0.72-0.96). Among new users of ADHD medications, the adjusted RR was 0.77 (95% CI, 0.63-0.94). The adjusted RR for current use vs remote use was 1.03 (95% CI, 0.86-1.24); for new use vs remote use, the adjusted RR was 1.02 (95% CI, 0.82-1.28); the upper limit of 1.28 corresponds to an additional 0.19 events per 1000 person-years at ages 25-44 years and 0.77 events per 1000 person-years at ages 45-64 years.Among young and middle-aged adults, current or new use of ADHD medications, compared with nonuse or remote use, was not associated with an increased risk of serious cardiovascular events. Apparent protective associations likely represent healthy-user bias.
