High Prevalence Of Polypharmacy Research Articles

Medication use among the oldest old in the Faroe Islands-A national cross-sectional study.

Aging is often associated with an increasing number of comorbidities that warrant use of multiple drugs which increases the use of potentially inappropriate medications (PIMs), drug-drug interactions (DDIs) and drug-related problems (DRPs). The aim is to assess the prevalence of polypharmacy, PIMs, DDIs and DRPs among Faroese residents aged ≥90 years. In this population-based cross-sectional study, 494 individuals ≥90 years were invited and 298 (60%) participated. A pharmacist-led medication review was performed based on self-information, electronic patient journal and the Faroese Prescription Registry. The prevalence of polypharmacy was 74% with no sex-difference. Approximately 60% of participants used PIMs, primarily benzodiazepines and proton pump inhibitors, the latter being a frequently implicated medication in DRPs. Opioid use was low compared with other Nordic studies. DRPs were observed for 79% with discrepancies in the medication lists as the most common cause, and DDIs were identified for 47% of participants, mostly moderately clinically relevant DDIs. In conclusion, the medication use among the oldest old Faroese resembled that in other Nordic countries with a high prevalence of polypharmacy and use of PIMs, especially PPIs and benzodiazepines. However, no sex-difference was noted in medication use and the use of opioids was low.

Definition of Polypharmacy in Heart Failure: A Scoping Review of the Literature.

Patients with heart failure (HF) have a high prevalence of polypharmacy, which can lead to drug interactions, cognitive impairment, and medication non-compliance. However, the definition of polypharmacy in these patients is still inconsistent. The aim of this scoping review was to find the most common definition of polypharmacy in HF patients. We conducted a scoping review searching Medline, Embase, CINAHL, and Cochrane using terms including polypharmacy, HF and deprescribing, which resulted in 7,949 articles. Articles without a definition of polypharmacy in HF patients and articles which included patients < 18 years of age were excluded; only 59 articles were included. Of the 59 articles, 49% (n = 29) were retrospective, 20% (n = 12) were prospective, 10% (n = 6) were cross-sectional, and 27% (n = 16) were review articles. Twenty percent (n = 12) of the articles focused on HF with reduced ejection fraction, 10% (n = 6) focused on HF with preserved ejection fraction and 69% (n = 41) articles either focused on both diagnoses or did not clarify the specific type of HF. The most common cutoff for polypharmacy in HF was five medications (59%, n = 35). There was no consensus regarding the inclusion or exclusion of over-the-counter medications, supplements, or vitamins. Some newer studies used a cutoff of 10 medications (14%, n = 8), and this may be a more practical and meaningful definition for HF patients.

The comorbidity profiles and medication issues of patients with multiple system atrophy: a systematic cross-sectional analysis

BackgroundMultiple system atrophy (MSA) is a complex and fatal neurodegenerative movement disorder. Understanding the comorbidities and drug therapy is crucial for MSA patients’ safety and management.ObjectivesTo investigate the pattern of comorbidities and aspects of drug therapy in MSA patients.MethodsCross-sectional data of MSA patients according to Gilman et al. (2008) diagnostic criteria and control patients without neurodegenerative diseases (non-ND) were collected from German, multicenter cohorts. The prevalence of comorbidities according to WHO ICD-10 classification and drugs administered according to WHO ATC system were analyzed. Potential drug-drug interactions were identified using AiDKlinik®.ResultsThe analysis included 254 MSA and 363 age- and sex-matched non-ND control patients. MSA patients exhibited a significantly higher burden of comorbidities, in particular diseases of the genitourinary system. Also, more medications were prescribed MSA patients, resulting in a higher prevalence of polypharmacy. Importantly, the risk of potential drug-drug interactions, including severe interactions and contraindicated combinations, was elevated in MSA patients. When comparing MSA-P and MSA-C subtypes, MSA-P patients suffered more frequently from diseases of the genitourinary system and diseases of the musculoskeletal system and connective tissue.ConclusionsMSA patients face a substantial burden of comorbidities, notably in the genitourinary system. This, coupled with increased polypharmacy and potential drug interactions, highlights the complexity of managing MSA patients. Clinicians should carefully consider these factors when devising treatment strategies for MSA patients.

A Naturalistic, Non-interventional Investigation of the Clinical and Sociodemographic Characteristics and Prescription Patterns in Patients With Psychotic Disorders at a Tertiary Care Facility in South Asia.

This study aimed to evaluate the trends in the sociodemographic, clinical, and prescription characteristics of patients with psychotic illnesses seen in the outpatient psychiatry department of a tertiary care facility. Between March 2021 and April 2022, a cross-sectional, prospective, observational, naturalistic, non-interventional study was conducted. A total of two hundred prescriptions were analyzed. To assess the rationality of prescriptions, World Health Organization (WHO) indicators were also computed. With a range of 18 to 75 years, the cohort's mean age was 40.26 years, and its average disease duration was 10.75 years. Sixty-seven patients (68.5%) were diagnosed with schizophrenia. Of the 200 prescriptions that were analyzed, 13 antipsychotic prescriptions were written 343 times. Olanzapine was prescribed as an antipsychotic the most frequently (132, 66%), followed by clozapine (75, 37.5%). Haloperidol (41, 20.5%), trifluoperazine (3, 1.5%), loxapine (1, 0.5%), and flupenthixoldepot (1, 0.5%) were the most commonly prescribed typical antipsychotics. 91% (181/200) of patients received prescriptions for other drugs in addition to antipsychotics.Trihexyphenidyl (45%), escitalopram (30%), clonazepam (26.5%), sodium valproate (10%), propranolol (10.5%), and modafinil (9.5%) were the most frequently prescribed concurrent medicines.Forty-eight percent (95/200) of prescriptions demonstrated polypharmacy. Among patients, the frequency of antipsychotic prescriptions was 1 in 44% (88/200), 2 in 36.50% (73/200), 3 in 17% (34/200), 4 in 0.5% (1/200), and 5 again in 0.5% (1/200). Conclusions:On average, the cohort of the current study was young. The commonest diagnosis was mainly schizophrenia. Atypical antipsychotics accounted for the majority of antipsychotic prescriptions in the current study. In this study, a high prevalence of polypharmacy was noted.

Psychotropic medicines' prevalence, patterns and effects on cognitive and physical function in older adults with intellectual disability in Ireland: longitudinal cohort study, 2009-2020.

The frequent prescribing of psychotropics and high prevalence of polypharmacy among older adults with intellectual disabilities require close monitoring. To describe change in prevalence, predictors and health outcomes of psychotropic use during the four waves (2009/2010, 2013/2014, 2016/2017, 2019/2020) of the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS-TILDA). Eligible participants were adults (≥40 years) with intellectual disabilities who participated in all four waves of IDS-TILDA and who reported medication use for the entire period. Differences between groups were tested using Cochran's Q test for binary variables and the McNemar-Bowker test for variables with more than two categories. Generalised estimating equation models were used to assess associations between psychotropic use, participants' characteristics and health outcomes. Across waves (433 participants) there were no significant differences in prevalence of psychotropic use (61.2-64.2%) and psychotropic polypharmacy (42.7-38.3%). Antipsychotics were the most used subgroup, without significant change in prevalence between waves (47.6-44.6%). A significant decrease was observed for anxiolytics (26.8-17.6%; P < 0.001) and hypnotics/sedatives (14.1-9.0%; P < 0.05). A significant increase was recorded for antidepressants (28.6-35.8%; P < 0.001) and mood-stabilising agents (11.5-14.6%; P < 0.05). Psychotropic polypharmacy (≥2 psychotropics) was significantly associated with moderate to total dependence in performing activities of daily living over the 10-year period (OR = 1.80, 95% CI 1.21-2.69; P < 0.05). The study indicates an increase in usage of some classes of psychotropic, a reduction in others and no change in the relatively high rate of antipsychotic use over 10 years in a cohort of older adults with intellectual disabilities and consequent risk of psychotropic polypharmacy and medication-related harm.

Patients' Characterization, Pattern of Medication Use, and Factors Associated with Polypharmacy: A Cross-Sectional Study Focused on Eight Units of the Portuguese National Network for Long-Term Integrated Care.

The Portuguese National Network for Long-term Integrated Care (RNCCI) comprises several Units for Integrated Continuous Care (UCCIs) that provide medical, nursing, and rehabilitation care. This study aimed to evaluate the demographic and medical characteristics of patients admitted to the RNCCI, their patterns of medication use, and factors associated with polypharmacy. An observational, retrospective, cross-sectional, multicenter study was performed. This study population consisted of 180 patients. Polypharmacy status was divided into two groups: non-polypharmacy (taking ≤ 4 drugs) and polypharmacy (taking ≥ 5 drugs). Bivariate analysis and multivariate logistic regression analysis were used to determine the influence of predictor factors such as demographic and medical characteristics on the polypharmacy status during the UCCI stays. This study population (mean age of 78.4 ± 12.3 years, range 23-102 years, 59% female) was prescribed a median of 8 medications. Approximately 89.4% of the patients were taking ≥ 5 drugs, demonstrating that polypharmacy is highly prevalent in Portuguese RNCCI residents of the eight UCCIs studied. A subsequent analysis with multivariate logistic regression found that polypharmacy status was significantly associated with the unit of internment (facility) when compared to facility E with H and with the Charlson Comorbidity Index (CCI). The high prevalence of polypharmacy and the associated factors show that it is urgent to improve pharmacotherapy regimens through periodic monitoring and review of patients' therapeutic lists, an area in which pharmacists play a very important role.

Polypharmacy and pattern of medication use among patients with gastroesophageal reflux disease: results from Pars Cohort study

BackgroundGastroesophageal Reflux Disease (GERD) is a common chronic condition. Its chronic nature may affect the pattern of medication use. This study aimed to investigate the prevalence, associated factors, and patterns of polypharmacy and medication use among GERD patients in southwestern Iran.MethodsWe used data from the Pars Cohort Study. We classified drugs using the Anatomical Therapeutic Chemical classification system. The Lexicomp® database was used to assess potential drug-drug interactions. Multivariable Poisson regression was applied. Adjusted prevalence ratio (PR) and its 95% confidence interval (CI) were estimated.ResultsA total of 9262 participants were included. Among 2,325 patients with GERD, age-standardized prevalence of polypharmacy was 9.5% (95% CI: 7.5%, 11.6%) in males, and 19.3% (95% CI: 17.2%, 21.4%) in females. The PR of experiencing Polypharmacy by GERD patients compared to non-GERD patients was 1.82 (95% CI: 1.61, 2.05%). Multimorbidity (PR: 3.33; CI: 2.66, 4.15), gender (PR: 1.68; CI: 1.30, 2.18), and metabolic syndrome (PR: 1.77; CI: 1.45, 2.15) were associated with polypharmacy among GERD patients. Drugs for acid-related disorders were the most common used drugs among men, women and elders. We found that 13.9%, 4.2%, and 1.1% of GERD patients had type C, D and X drug interactions, respectively.ConclusionGERD is correlated with a higher prevalence of polypharmacy. Among GERD patients, females, those with multi-morbidities, and those with metabolic syndrome may be affected more by polypharmacy. Considering the fairly high rate of interactions identified, a review of the medication list is essential when approaching GERD patients, and physicians must check for medications that may worsen GERD.

Frailty and spatialization of older adults in the city of Uberlândia with IVCF-20.

To describe the functional clinical profile of elderly people linked to primary health care, using the Functional Clinical Vulnerability Index (IVCF-20) and to spatialize those with the greatest functional decline by primary health care units in the municipality of Uberlândia, in the state of Minas Gerais (MG), in the year 2022. A cross-sectional study with secondary data from the Municipal Health Department of Uberlândia-MG. The variables were compared using Student's t-test, Mann Whitney test, Pearson's chi-square, and multinomial logistic regression to obtain the independent effect of each variable. The significance level adopted was 5% (p < 0.05). The georeferenced database in ArcGIS® was used. 47,182 older adults were evaluated with a mean age of 70.3 years (60 to 113 years), 27,138 of whom were women (57.52%), with a clear predominance of low-risk or robust older adults (69.40%). However, 11.09% are high-risk older adults and 19.52% are at risk of frailty. Older men had independently lower odds of moderate and high risk compared to older women (OR = 0.53; p < 0.001). A high prevalence of polypharmacy was observed, 21.40% of the older adult population, particularly in frail older adults, with a prevalence of 63.08%. There was a greater distribution of frail older adults around the central region of the municipality and in health units with a larger coverage area. The IVCF-20 made it possible to screen frailty in primary health care. The instrument is capable of stratifying the risk of older adults in health care networks through primary health care, enabling the application of individualized preventive, promotional, palliative, or rehabilitative interventions, according to the clinical functional stratum of the older adult and the compromised functional domains. Risk stratification and spatial distribution of the frailest older adults can be a good strategy for qualifying health professionals with the aim of maximizing the autonomy and independence of the older adults.

The need for standardised outcomes in pharmacist interventions in chronic kidney disease: a systematic review of randomised controlled trials

Abstract Introduction People living with chronic kidney disease (CKD) have a high prevalence of polypharmacy. Polypharmacy presents a significant burden and the risk of inappropriate prescribing in people with CKD is a cause for concern due to age-related changes associated with pharmacodynamics (e.g., increased sensitivity towards adverse drug events) and pharmacokinetics (e.g., reduced renal excretion)1. Strategies for the successful management of CKD include controlling cardiovascular risk factors, lifestyle modifications, and treating comorbidities. There is an ever-increasing role of pharmacists in managing CKD, from medication reviews to optimising risk factors2. However, currently, there is a lack of quality data on the impact of pharmacists in CKD management; this is partly due to the wide range of variable outcomes used in studies and a lack of standardised outcome reporting. Aim We aimed to explore the range of outcomes and measures used in pharmacist-led research in CKD that could be recommended for standardised use. Methods A systematic review of randomised controlled trials (RCTs) of interventions in a CKD population with significant pharmacist input was conducted. Searches were conducted in the following databases: MEDLINE, Scopus, and Web of Science. Databases were searched until January 2022; searches were re-run in February 2023. Data was extracted pertaining to clinical (e.g., mortality), economic (e.g., healthcare-associated costs), and humanistic (e.g., quality of life (QoL)) outcomes. Ethical approval was not required because this review is based exclusively on published literature. Results 38 reports of 32 RCTs were identified, with sample sizes of RCTs ranging from 24 to 32,917 participants. Most studies were conducted in the United States (16/32), whilst one was conducted in the United Kingdom. Of these, 12/32 (37.5%) were exclusively conducted in people on dialysis, six in kidney transplant recipients, 13 in those with non-dialysis dependent CKD, and one study in a mixed cohort. The interventions delivered by pharmacists were heterogenous and included medicine reconciliation, patient counselling, and dose adjustment. A wide range of outcomes were reported including blood pressure, CKD progression, and QoL. The most frequently reported outcome was blood pressure, which was used as an endpoint in 12/32 (37.5%) studies. There was significant heterogeneity in the measures and methods used for reported outcomes. For example, in 11/32 studies (34.4%) where medication adherence was assessed, five separate outcome measures were used: variations of the Morisky Medication Scale (6/11), pharmacy refill records (2/11), Basel Assessment of Adherence to Immunosuppressive Medication Scale (1/11), a comparison of the quantity of medications prescribed with those present in containers (1/11), and the endstage renal disease adherence questionnaire (1/11). Discussion/Conclusion Nephrology is well adept in the use of standardised core outcome sets (COS) (e.g., the Standardised Outcomes in Nephrology initiative)3, yet such COS may not be appropriate to more specialist interventions where different or more relevant outcomes may be needed. The plethora of outcome measures identified in our review suggests a better standardisation of reporting is needed to facilitate consolidation of pharmacy research in the area and further support for the role of the pharmacist in CKD management.

Worldwide Prevalence of Polypharmacy: A Systematic Review.

The present study has compiled the prevalence of polypharmacy worldwide and assessed the prevalence of polypharmacy in different populations, including community-dwelling individuals, hospitalized patients, and institutionalized patients. This systematic review was conducted and reported according to the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. A systematic search of electronic databases, including PubMed, Web of Science, and Scielo, was performed in March 2021 without any date and language restrictions. Combinations of the following keywords were used for the search strategy: polypharmacy OR multiple medications OR multiple medicines OR multiple drug AND prevalence. Based on the search and inclusion criteria, two hundred and eight studies (73,076,167 individuals) were selected for inclusion in the systematic review. It was observed that there is a wide variation in the prevalence of polypharmacy between studies. The prevalence of polypharmacy was found to be 30.2%, 61.7%, and 56.9% for community-dwelling individuals, hospitalized patients, and institutionalized patients, respectively. Based on the analyses, this systematic review has demonstrated a wide variation in the prevalence of polypharmacy between studies and countries and a high prevalence of polypharmacy in institutionalized and hospitalized patients.

Prescribed Versus Taken Polypharmacy and Drug-Drug Interactions in Older Cardiovascular Patients during the COVID-19 Pandemic: Observational Cross-Sectional Analytical Study.

The study aimed to assess clinical pharmacology patterns of prescribed and taken medications in older cardiovascular patients using electronic health records (EHRs) (n = 704) (2019-2022). Medscape Drug Interaction Checker was used to identify pairwise drug-drug interactions (DDIs). Prevalence rates of DDIs were 73.5% and 68.5% among taken and prescribed drugs, respectively. However, the total number of DDIs was significantly higher among the prescribed medications (p < 0.05). Serious DDIs comprised 16% and 7% of all DDIs among the prescribed and taken medications, respectively (p < 0.05). Median numbers of DDIs between the prescribed vs. taken medications were Me = 2, IQR 0-7 vs. Me = 3, IQR 0-7 per record, respectively. Prevalence of polypharmacy was significantly higher among the prescribed medications compared with that among the taken drugs (p < 0.05). Women were taking significantly more drugs and had higher prevalence of polypharmacy and DDIs (p < 0.05). No sex-related differences were observed in the list of prescribed medications. ICD code U07.1 (COVID-19, virus identified) was associated with the highest median DDI number per record. Further research is warranted to improve EHR structure, implement patient engagement in reporting adverse drug reactions, and provide genetic profiling of patients to avoid potentially serious DDIs.

Relationship Between Medical Therapy, Long-Term Care Insurance, and Comorbidity in Elderly Patients With Heart Failure With Systolic Dysfunction.

Although guideline-directed medical therapy (GDMT), including β-blockers, angiotensin-converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARBs), and mineralocorticoid receptor antagonists (MRAs), improves survival and quality of life, most patients with heart failure with reduced (HFrEF) and mildly reduced (HFmrEF) ejection fraction are treated with inadequate medications. We investigated the prescription patterns of GDMT in elderly patients with HFrEF and HFmrEF and their characteristics, including the certification of long-term care insurance (LTCI), which represents frailty and disability.Methods and Results: This retrospective cross-sectional study analyzed 1,296 elderly patients with symptomatic HFrEF and HFmrEF with diuretic use (median age 78 years; 63.8% male; median left ventricular ejection fraction 40%). Prescription rates of GDMT were inadequate (ACEi, ARBs, β-blockers, and MRAs: 27.0%, 30.1%, 54.1%, and 41.9%, respectively). LTCI certification was independently associated with reduced prescription of all medications (ACEi/ARB: odds ratio [OR] 0.591, 95% confidence interval [CI] 0.449-0.778, P=0.001; β-blockers: OR 0.698, 95% CI 0.529-0.920, P<0.001; MRAs: OR 0.743, 95% CI 0.560-0.985, P=0.052). Patients with LTCI certification also had a high prevalence of polypharmacy and prescription of diuretics. Vulnerable patients with LTCI may be an explanation for the challenges in implementing GDMT, and communicating is required for favorable heart failure care in this population.

Management of Polypharmacy and Potential Drug-Drug Interactions in Patients with Mycobacterial Infection: A 1-Year Experience of a Multidisciplinary Outpatient Clinic.

In 2022, we opened an outpatient clinic for the management of polypharmacy and potential drug-drug interactions (pDDIs) in patients with mycobacterial infection (called GAP-MyTB). All patients who underwent a GAP-MyTB visit from March 2022 to March 2023 were included in this retrospective analysis. Fifty-two patients were included in the GAP-MyTB database. They were given 10.4 ± 3.7 drugs (2.8 ± 1.0 and 7.8 ± 3.9 were, respectively, antimycobacterial agents and co-medications). Overall, 262 pDDIs were identified and classified as red-flag (2%), orange-flag (72%), or yellow-flag (26%) types. The most frequent actions suggested after the GAP-MyTB assessment were to perform ECG (52%), therapeutic drug monitoring (TDM, 40%), and electrolyte monitoring (33%) among the diagnostic interventions and to reduce/stop proton pump inhibitors (37%), reduce/change statins (14%), and reduce anticholinergic burden (8%) among the pharmacologic interventions. The TDM of rifampicin revealed suboptimal exposure in 39% of patients that resulted in a TDM-guided dose increment (from 645 ± 101 to 793 ± 189 mg/day, p < 0.001). The high prevalence of polypharmacy and risk of pDDIs in patients with mycobacterial infection highlights the need for ongoing education on prescribing principles and the optimal management of individual patients. A multidisciplinary approach involving physicians and clinical pharmacologists could help achieve this goal.

Medication Use Status and Its Related Factors among Older Adults in Kerman, Iran

Introduction: Older adults are the largest group of medication users in each society. Since medications act differently in seniors compared with younger patients, great considerations are required regarding the effects and side effects of medications in the older adults. The present study aimed to determine the status of medication use and its related factors among older adults in Kerman city, Iran.&#x0D; &#x0D; Methods: In the cross-sectional study, 388 seniors were selected using multistage cluster sampling from the population covered by comprehensive health centers in Kerman in 2021. Demographic information questions (age, gender, education level, marital status, life status, substance abuse, income, and health insurance status), a question regarding medication usage status and a question regarding disease that the elderly are currently suffering from, Montreal Cognitive Assessment Questionnaire, Geriatric Depression Scale, and Sleep Disorder Questionnaire were used for data collection. The data were analyzed using SPSS software by running Chi-square and multiple logistic regression tests.&#x0D; &#x0D; Results: The average number of medications used per day was 4.59 and 53.5% of the participants used five or more medications concomitantly. Antihypertensive medications had the highest prevalence (64.3%) followed by anti-hyperlipidemic (43.6%) and Supplements (41.3%). A significant correlation was found between the participants' frequency of medication use and their gender, income, primary insomnia, and cognitive impairment (p &lt; 0.001). However, medication use had no significant association with the senior's age, marital status, education level, living status, substance abuse, and health insurance (p &lt; 0.05). The risk of polypharmacy was 2.15 times higher in the elderly women than men (p = 0.001) and 0.45 times higher in participants with depression than non-depressed seniors (p = 0.011).&#x0D; &#x0D; Conclusion: The high prevalence of polypharmacy indicates an unfavorable status of medication use among older adults in Kerman. So, authorities are required to provide educational information about polypharmacy to aged groups.

Polypharmacy and Aging in People Living with HIV: 6 Years of Experience in a Multidisciplinary Outpatient Clinic.

Despite the availability of potent antiretroviral drugs, the management of human immunodeficiency virus (HIV) infection still presents some important challenges, especially in older patients who often experience age-related comorbidities and complex polypharmacy. To describe the results of our 6 year experience with the outpatient clinic [Gestione Ambulatoriale Politerapie (GAP)] for the management of polypharmacy in people living with HIV (PLWH). Demographic characteristics, antiretroviral regimens, and number and type of comedications were collected in all PLWH included in the database of GAP from September 2016 to September 2022. Therapies were stratified based on the number of anti-HIV drugs (dual versus triple regimens) and on the presence of pharmacokinetic boosters (ritonavir or cobicistat). A total of 556 PLWH were included in the GAP database. Overall, the enrolled patients were administered 4.2 ± 2.7 drugs (range 1-17) in addition to antiretroviral therapies. The number of comedications greatly increased with age (3.0 ± 2.2 versus 4.1 ± 2.5 versus 6.3 ± 3.2 in PLWH aged < 50 versus 50-64 versus > 65 years; p < 0.001 for all comparisons). PLWH on dual antiretroviral therapies were significantly older (58 ± 9 versus 54 ± 11 years; p < 0.001) and were concomitantly treated with more drugs (5.1 ± 3.2 versus 3.8 ± 2.5; p < 0.001) compared with those on triple therapies. A significant reduction of boosted antiretroviral regimens (53% versus 23%; p < 0.001) and in the number of comedications (4.0 ± 2.9 versus 3.1 ± 2.2 drugs; p < 0.001) was observed in the subgroup of patients (n = 198) with two GAP visits. The high prevalence of polypharmacy in PLWH, especially among older adults, place these patients at high risk for clinically relevant drug-drug interactions (DDIs). A multidisciplinary approach involving physicians and clinical pharmacologists could help to optimize medication regimens associated with reduced risk.

Clozapine in first episode psychosis – the experience of a Portuguese center

IntroductionAntipsychotics are the standard in the treatment of first psychotic episodes. Although the majority of patients respond to the established treatment, it is currently known that there is a subgroup of patients whose response is not satisfactory. In this group, the subsequent response to a new antipsychotic is generally poor. Clozapine is an antipsychotic with a unique profile, with demonstrated efficacy and approval in the treatment of treatment-resistant schizophrenia. Its role in the first psychotic episodes remains unclear and its use is, to say the least, controversial.ObjectivesThis work aims to analyze and evaluate the use of clozapine in patients with a first psychotic episode, taking into account the experience of a Portuguese Hospital Center.MethodsWe carried out a retrospective study, including all patients admitted to the inpatient clinic of adults with a first psychotic episode, in the Department of Psychiatry of Centro Hospitalar Universitário of São João, in Oporto, between 2007 and 2020. Clinical and socio-demographic data were collected.We performed a retrospective analysis of patients who, at discharge, were medicated with clozapine, proceeding to a descriptive analysis.ResultsIn this case series, we intended to describe the cases of patients in whom the use of clozapine in the first psychotic episode was initiated. All patients were discharged with the diagnosis of Schizophrenia. Prior to the introduction of clozapine, patients were treated with other antipsychotics, normally two. Patients taking clozapine were younger and had a longer duration of untreated psychosis. They had also longer length of hospital stay. The pattern of prescribing antipsychotics in the first and subsequent episodes has generally been extensively studied. However, the use of clozapine in the first episodes remains unclear.In the literature, and despite clozapine being considered one of the most effective antipsychotics, there is a high prevalence of polypharmacy and a significant delay in its use in the first episodes.Notwithstanding the unfavorable metabolic and hematological profile of clozapine, compared to other antipsychotics, in terms of hospitalization, mortality and discontinuation rates for all causes, it demonstrates a pattern of superiority.ConclusionsThe superiority in effectiveness of clozapine is well established, despite its underutilization and frequent delay in its introduction.The clinicians attitude remains a significant barrier to the commencement of clozapine, although it is important to define and characterize better potential groups of eligible patients. Education resources for clinicians as well as services specifically dedicated to early identification and management of eligible patients would be beneficial.Disclosure of InterestNone Declared

Sarcopenia is associated with a greater risk of polypharmacy and number of medications: a systematic review and meta-analysis.

Polypharmacy in older adults is associated with multiple negative consequences that may affect muscular function, independently from the presence of medical conditions. The aim of this systematic review and meta-analysis was to investigate the association of sarcopenia with polypharmacy and higher number of medications. A systematic literature search of observational studies using PubMed, Web of Science, Scopus and Cochrane Library databases was conducted from inception until June 2022. To determine if sarcopenia is associated with a higher risk of polypharmacy and increased number of medications, a meta-analysis using a random-effects model was used to calculate the pooled effects (CRD42022337539). Twenty-nine studies were included in the systematic review and meta-analysis. Sarcopenia was associated with a higher prevalence of polypharmacy (odds ratio [OR]: 1.65, 95% confidence interval [CI] [1.23, 2.20], I2 =84%, P<0.01) and higher number of medications (mean difference: 1.39, 95% CI [0.59, 2.19], I2 =95%, P<0.01) compared with individuals without sarcopenia. Using meta-regression, a high variance was observed due to different populations (i.e., community-dwelling, nursing home residents, inpatients, outpatients) for both outcomes of polypharmacy (r=-0.338, SE=0.1669, 95% CI [-0.67, -0.01], z=-2.03, P=0.04) and number of medications (r=0.589, SE=0.2615, 95% CI [0.08, 1.10], z=2.25, P=0.02). This systematic review and meta-analysis reported a significantly increased risk of polypharmacy and higher number of medications in people with sarcopenia compared with individuals without this condition. Future research should clarify whether the specificity and number of medications is a direct contributor in accelerating the progression of muscle wasting and dysfunction contributing to sarcopenia in older adults.

Polypharmacy in patients with chronic-degenerative diseases in a remote community, Puebla- México.

Objective: To determine if patients with chronic degenerative diseases between 50-90 years of age have polypharmacy and drug interactions, at the Huajoyuca Health Center of Palacios, between June 2018-June 2019. Methodology: A descriptive, observational, non-experimental, statistical, retrospective, cross-sectional, unicentric research was carried out. The sample consisted of 56 files according to the inclusion criteria. Data were analyzed according to descriptive statistics and frequency histograms. Results: The mean age is 67.11 ± 9.6 years. There was a higher prevalence of polypharmacy in the 60-69 age range. Due to excessive medication consumption, women make up 82 percent of those affected. Patients with chronic-degenerative disorders are the most likely to have polypharmacy, and those with comorbid conditions even more, it was observed that the consumption and frequency of medications per patient is 4.08 ± 1.56 medications. The top drugs consumed daily are metformin (17.41%), hydrochlorothiazide (12.05%), B vitamin, acetylsalicylic acid glibenclamide with (11.16%), losartan (8.03%), enalapril (6.69%), captopril (4.91 %). 38 patients with (68%) had minor polypharmacy, 17 patients with (30%) had major polypharmacy, and 1 patient with (2%), had excess polypharmacy. Conclusion: In order from highest to lowest, patients with type 2 diabetes mellitus have minor polypharmacy, unlike hypertensive and dyslipidemic patients. The gender most affected by polypharmacy is the female with 82% vs. 18% the male gender of the population studied.

Polypharmacy Patterns in Multimorbid Older People with Cardiovascular Disease: Longitudinal Study.

(1) Introduction: Cardiovascular disease is associated with high mortality, especially in older people. This study aimed to characterize the evolution of combined multimorbidity and polypharmacy patterns in older people with different cardiovascular disease profiles. (2) Material and methods: This longitudinal study drew data from the Information System for Research in Primary Care in people aged 65 to 99 years with profiles of cardiovascular multimorbidity. Combined patterns of multimorbidity and polypharmacy were analysed using fuzzy c-means clustering techniques and hidden Markov models. The prevalence, observed/expected ratio, and exclusivity of chronic diseases and/or groups of these with the corresponding medication were described. (3) Results: The study included 114,516 people, mostly men (59.6%) with a mean age of 78.8 years and a high prevalence of polypharmacy (83.5%). The following patterns were identified: Mental, behavioural, digestive and cerebrovascular; Neuropathy, autoimmune and musculoskeletal; Musculoskeletal, mental, behavioural, genitourinary, digestive and dermatological; Non-specific; Multisystemic; Respiratory, cardiovascular, behavioural and genitourinary; Diabetes and ischemic cardiopathy; and Cardiac. The prevalence of overrepresented health problems and drugs remained stable over the years, although by study end, cohort survivors had more polypharmacy and multimorbidity. Most people followed the same pattern over time; the most frequent transitions were from Non-specific to Mental, behavioural, digestive and cerebrovascular and from Musculoskeletal, mental, behavioural, genitourinary, digestive and dermatological to Non-specific. (4) Conclusions: Eight combined multimorbidity and polypharmacy patterns, differentiated by sex, remained stable over follow-up. Understanding the behaviour of different diseases and drugs can help design individualised interventions in populations with clinical complexity.

Characterisation of institutionalised Portuguese older adult fallers: is there a place for pharmacist intervention? A preliminary study.

Falls are a major public health issue, given their prevalence and social impact. Older adults living in long-term care facilities (LTCF) are at greater risk of injury resulting from a fall due to multiple factors, such as nutritional, functional/cognitive impairment, postural instability, polypharmacy, and the presence of potentially inappropriate medications (PIMs). Medication management in LTCF is complex and often sub-optimal and might be crucial for falls. Pharmacist intervention is important, since they have a unique knowledge of medication. However, studies mapping the impact of pharmaceutical activities in Portuguese LTC settings are scarce. This study aims to assess the characteristics of older adult fallers living in LTFCs and examine the relationship between falling and several factors in this population. We also intend to explore the prevalence of PIMs and their relationship with the occurrence of falls. The study was conducted in two long-term care facilities for elderly people, in the central region of Portugal. We included patients aged 65 and older with no reduced mobility or physical weakness and with the ability to understand spoken and written Portuguese. The following information was assessed: sociodemographic characteristics, comorbidities, polypharmacy, fear of falling, functional, nutritional and cognitive status. PIMs were evaluated according to the Beers criteria (2019). A total of 69 institutionalised older adults, 45 women and 24 men, with a mean age of 83.14 ± 8.87 years were included. The prevalence of falls was 21.74% Out of these, 46.67% (n=7) fell once, 13.33% (n=2) fell twice, and 40% (n=6) fell 3 or more times. Fallers were mainly women, had lower levels of education, were well nourished, had moderate to severe levels of dependence, and displayed moderate cognitive impairment. All adult fallers had a fear of falling. The main comorbidities of this population were related to the cardiovascular system. Polypharmacy was present in every patient, and at least one PIM was identified in 88.41% of the subjects. Fear of falling (FOF) and cognitive impairment (in subjects with 1 to 11 years of education) showed statistically significant associations with the occurrence of falls (p=0.005 and p=0.05, respectively). No significant differences were found between fallers and non-fallers for any other factors. This present study is a preliminary contribution to characterise a group of older adult fallers living in Portuguese LTCFs and demonstrated that fear of falling and cognitive impairment are associated with the occurrence of falls in this population. The high prevalence of polypharmacy and PIMs emphasises the need for tailored interventions featuring the collaboration of a pharmacist to optimise medication management in this population.
