Polypharmacy and Deprescribing in Older Adults.

Older adults commonly end up on many medications. Deprescribing is an important part of individualizing care for older adults. It is an opportunity to discuss treatment options and revisit medications that may not have been reassessed in many years. A large evidence base exists in the field, suggesting that deprescribing is feasible and safe, though questions remain about the potential clinical benefits. Deprescribing research faces a myriad of challenges, such as identifying and employing the optimal outcome measures. Further, there is uncertainty about which deprescribing approaches are likely to be most effective and in what contexts. Evidence on barriers and facilitators to deprescribing has underscored how deprescribing in routine clinical practice can be complex and challenging. Thus, finding practical, sustainable ways to implement deprescribing is a priority for future research in the field.

Implementation considerations of deprescribing interventions: A scoping review.

Over half of older adults experience polypharmacy, including medications that may be inappropriate or unnecessary. Deprescribing, which is the process of discontinuing or reducing inappropriate and/or unnecessary medications, is an effective way to reduce polypharmacy. This review summarizes (1) the process of deprescribing and conceptual models and tools that have been developed to facilitate deprescribing, (2) barriers, enablers, and factors associated with deprescribing, and (3) characteristics of deprescribing interventions in completed trials, as well as (4) implementation considerations for deprescribing in routine practice. In conceptual models of deprescribing, multilevel factors of the patient, clinician, and health-care system are all related to the efficacy of deprescribing. Numerous tools have been developed for clinicians to facilitate deprescribing, yet most require substantial time and, thus, may be difficult to implement during routine health-care encounters. Multiple deprescribing interventions have been evaluated, which mostly include one or more of the following components: patient education, medication review, identification of deprescribing targets, and patient and/or provider communication about high-risk medications. Yet, there has been limited consideration of implementation factors in prior deprescribing interventions, especially with regard to the personnel and resources in existing health-care systems and the feasibility of incorporating components of deprescribing interventions into the routine care processes of clinicians. Future trials require a more balanced consideration of both effectiveness and implementation when designing deprescribing interventions.

Fast polypharmacy side effect prediction using tensor factorization.

MOTIVATION: Adverse reactions from drug combinations are increasingly common, making their accurate prediction a crucial challenge in modern medicine. Laboratory-based identification of these reactions is insufficient due to the combinatorial nature of the problem. While many computational approaches have been proposed, tensor factorization (TF) models have shown mixed results, necessitating a thorough investigation of their capabilities when properly optimized. RESULTS: We demonstrate that TF models can achieve state-of-the-art performance on polypharmacy side effect prediction, with our best model (SimplE) achieving median scores of 0.978 area under receiver-operating characteristic curve, 0.971 area under precision-recall curve, and 1.000 AP@50 across 963 side effects. Notably, this model reaches 98.3% of its maximum performance after just two epochs of training (approximately 4 min), making it substantially faster than existing approaches while maintaining comparable accuracy. We also find that incorporating monopharmacy data as self-looping edges in the graph performs marginally better than using it to initialize embeddings. AVAILABILITY AND IMPLEMENTATION: All code used in the experiments is available in our GitHub repository (https://doi.org/10.5281/zenodo.10684402). The implementation was carried out using Python 3.8.12 with PyTorch 1.7.1, accelerated with CUDA 11.4 on NVIDIA GeForce RTX 2080 Ti GPUs.

Association of polypharmacy scores with the long-term survival of patients with intact aortoiliac aneurysms and indication for repair.

OBJECTIVE/BACKGROUND: Our study analyzed the relationship between two polypharmacy scores (addition of chronic prescribed drugs [ACPDs] and Rx-Risk Comorbidity Index) and survival in patients with an intact abdominal aortic and/or common iliac aneurysm (AAA). METHODS: Consecutive retrospective, single-center cohort of patients attended for an intact AAA with indication for repair from 2008 to 2021. Demographic data, Charlson Comorbidity Index, AAA treatment, ACPD, and Rx-Risk polypharmacy scores were recorded at baseline. Main outcomes were the 5-year and long-term survival rates. The statistical analysis included Cox regression, area under the curve, and continuous net reclassification index. RESULTS: A total of 424 patients with AAA were evaluated (median age: 76 years; 92.2% male, median Charlson index 2), of whom 314 (74.1%) underwent intervention (80% endovascular and 20% open) and 110 (25.9%) did not. During follow-up (mean 4.6 years), 245 patients (57.8%) died, with 1-month, 1-year, and 5-year survival rates of 98.1%, 86.3%, and 52.7%, respectively. ACPD and Rx-Risk indices (median [interquartile range]: 6 [4-9] and 3 [0-5], respectively) were significantly and linearly associated (P < .001) with survival, with the best cutoff points at 5 and 0, respectively. An ACPD >5 (patients with >5 chronically prescribed drugs at baseline) and an Rx-Risk >0 were associated with a 45.2% (P = .038) and 102% (P = .002) increase in 5-year mortality, respectively, after adjustment for age, sex, Charlson index, and type of AAA treatment. Both polypharmacy indices improved significantly the discriminative power of the Charlson Comorbidity Index in predicting survival. CONCLUSIONS: Both ACPD and Rx-Risk polypharmacy scores are independently related to survival among patients with an intact AAA and indication for repair. Their behavior is similar, so the simple ACPD >5 appears to be sufficient to identify patients with lower survival rates.

Rethinking atherosclerotic cardiovascular disease prevention in the era of expanding therapies: could plaque stabilization reduce the need for lifelong treatments and polypharmacy?

PURPOSE OF REVIEW: This review examines current evidence on pharmacologically induced plaque stabilization in the context of a growing range of new therapies. It explores the potential for a paradigm shift in atherosclerotic cardiovascular disease (ASCVD) prevention, where treatments may not need to be lifelong to achieve lasting benefits. RECENT FINDINGS: Since 2015, over 14 novel therapies have been introduced, each shown to reduce ASCVD risk when added to standard care with statins and aspirin. More than 80% of ischemic heart disease patients are now eligible for one or more of these treatments, increasing the risk of polypharmacy, treatment burden, and adverse side effects. As more therapies become available, this challenge is expected to grow. Many of these treatments have demonstrated plaque regression and stabilization, as evidenced by both intravascular ultrasound and computed tomography angiography, which likely explains much of their efficacy. SUMMARY: The increasing number of novel therapies presents challenges in preventing ASCVD without leading to lifelong polypharmacy and increased patient burden. Since many of these drugs act through plaque stabilization, a new approach may be feasible - using these treatments for shorter durations to induce plaque regression, followed by less intensive maintenance therapies to preserve stability. This approach warrants further investigation in future studies.

Older adults' adherence to medications and willingness to deprescribe: A substudy of a randomized clinical trial.

Our study investigated the association between patients' willingness to have medications deprescribed and medication adherence. This longitudinal substudy of the 'Optimizing PharmacoTherapy In the Multimorbid Elderly in Primary CAre' (OPTICA) trial, a cluster randomized controlled trial, took place in Swiss primary care settings. Participants were aged ≥65 years and over, with ≥3 chronic conditions and ≥5 regular medications. At baseline, the 'revised Patient Attitudes Towards Deprescribing' (rPATD) questionnaire was measured. The A14-scale measured adherence (self-report) at the 12-month follow-up. Multilevel linear regression analyses adjusted for baseline variables were performed. Of the 298 participants, 45% were women, and the median age was 78. Participants reported a high level of adherence and willingness to have medications deprescribed. We did not find evidence for an association between patients' willingness to deprescribe and medication adherence. Further research is needed to explore the relationship between these concepts and to inform collaborative decisions about medicines in the context of polypharmacy.

Mobile applications on app stores for deprescribing: A scoping review.

Deprescribing is an evidence-based intervention to reduce potentially inappropriate medication use. Yet its implementation faces barriers including inadequate resources, training and time. Mobile applications (apps) on app stores could address some barriers by offering educational content and interactive features for medication assessment and deprescribing guidance. A scoping review was undertaken to examine existing deprescribing apps, identifying features including interactive and artificial intelligence (AI) elements. A comprehensive search was conducted in August 2023 to identify mobile apps with deprescribing content within the Apple and Google Play Stores. The apps found were screened for inclusion, and data on their features were extracted. Quality assessment was undertaken using the Mobile App Rating Scale. Six deprescribing-related apps were identified: the American Geriatrics Society Beers Criteria 2023, Dementia Training Australia Medications, Evidence-Based Medicine Guide, Information Assessment Method Medical Guidelines, MedGPT-Medical AI App, and Polypharmacy: Manage Medicines. These apps focused primarily on educating both patients/carers and healthcare professionals about deprescribing. Amongst them, two apps included interactive features, with one incorporating AI technology. While these features allowed for search queries and input of patient-level details, the apps provided limited personalised deprescribing advice. In terms of quality, the apps scored highly on functionality and information, and poorly on engagement and aesthetics. This review found deprescribing apps, despite being educational, have limitations in personalization and user engagement. Future research should prioritize evaluating their feasibility and user experience in clinical settings, and further explore how AI and interactivity could enhance the usefulness of these apps for deprescribing practices.

Medicine burden experiences of people living with HIV and association with stigma.

The medicine burden of people living with HIV (PLWH) is unknown. Between 2018 and 2020, participants completed a survey comprising outcome measures for medicine burden (LMQ-3) and stigma experiences (SSCI-8). Participants were HIV+ adults (≥18 years), using antiretrovirals (ARV) with or without non-ARV medicines, recruited via two outpatient clinics in southeast England and online via HIV charities across the UK. Spearman's correlations between medicine burden levels and stigma scores were calculated. Participants were mostly males (72%, 101/141) of mean (SD) age 48.6 (±12.31) years. Total number of medicines ranged from 1-20. High medicine burden was self-reported by 21.3% (30) and was associated with polypharmacy (≥ 5 medicines) (101.52 Vs 85.08, p = 0.006); multiple doses versus once daily regimes (109.31 Vs 85.65, p = 0.001); unemployment (98.23 Vs 84.46, p = 0.004); and ethnicity (97 Vs 86.85, p = 0.041 for non-White versus White participants). A correlation between medicine burden and stigma was observed (r = 0.576, p < 0.001). The LMQ-3 demonstrated adequate construct validity and reliability (domain loadings ranging 0.617-0.933 and Cronbach's α of 0.714-0.932). Assessment of medicine burden and psychosocial stigma in PLWH could enable identification of those needing additional support in future research and practice.

Polypharmacy and Bleeding Outcomes After Percutaneous Coronary Intervention.

BACKGROUND: Polypharmacy was reported to be associated with major bleeding in various populations. However, there are no data on polypharmacy and its association with bleeding in patients undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS: Among 12,291 patients in the CREDO-Kyoto PCI Registry Cohort-3, we evaluated the number of medications at discharge and compared major bleeding, defined as Bleeding Academic Research Consortium Type 3 or 5 bleeding, across tertiles (T1-3) of the number of medications. The median number of medications was 6, and 88.0% of patients were on ≥5 medications. The cumulative 5-year incidence of major bleeding increased incrementally with increasing number of medications (T1 [≤5 medications] 12.5%, T2 [6-7] 16.5%, and T3 [≥8] 20.4%; log-rank P<0.001). After adjusting for confounders, the risks for major bleeding of T2 (hazard ratio [HR] 1.21; 95% confidence interval [CI] 1.08-1.36; P=0.001) and T3 (HR 1.27; 95% CI 1.12-1.45; P<0.001) relative to T1 remained significant. The adjusted risks of T2 and T3 relative to T1 were not significant for a composite of myocardial infarction or ischemic stroke (HR 0.95 [95% CI 0.83-1.09; P=0.47] and HR 1.06 [95% CI 0.91-1.23; P=0.48], respectively). CONCLUSIONS: In a real-world population of patients undergoing PCI, approximately 90% were on ≥5 medications. Increasing number of medications was associated with a higher adjusted risk for major bleeding, but not ischemic events.

Trends in polypharmacy among U.S. adults with asthma, 2001-2020.

OBJECTIVE: This study aimed to evaluate trends in polypharmacy prevalence among adults with asthma in the United States. METHODS: Data from the 2001-2020 National Health and Nutrition Examination Survey were used to estimate the weighted prevalence of polypharmacy. Joinpoint regression analysis was conducted to evaluate trends in polypharmacy. Trends were first evaluated overall and then stratified by asthma severity and asthma control. A multivariable logistic regression model was used to identify factors associated with polypharmacy. RESULTS: From 2001 to 2020, a stable trend in polypharmacy among U.S. adults with asthma was observed (average annual percent change [AAPC]=1.02, p=0.71). Trends across different asthma severity were stable (mild asthma: AAPC=2.93, p=0.20; moderate asthma: AAPC=-2.22, p=0.35; severe asthma: AAPC=0.45, p=0.82). Trends in adults with good asthma control and those with poor control stayed constant (good control: AAPC=0.82, p=0.68; poor control: AAPC=-1.22, p=0.82). Several factors, including older age, females, Non-Hispanic Black, health insurance coverage, family income, number of healthcare visits, former smokers, multi-morbidities, asthma severity, and asthma control, were associated with polypharmacy. CONCLUSIONS: Polypharmacy prevalence has remained constant among U.S. adults with asthma over the past two decades. Despite a stable overall trend, disparities in polypharmacy prevalence persist across different asthma severity and control status, underscoring the need for tailored medication management to improve asthma care.

The Comorbidity-Polypharmacy Score as a Predictive Tool of Survival and Limb Salvage in Patients Undergoing Lower Limb Revascularization Procedures for Chronic Limb-Threatening Ischemia.

BACKGROUND: The comorbidity-polypharmacy score (CPPS) was created to evaluate the clinical burden of comorbidities in geriatric patients. It represents an objective tool to stratify patients' risk in different settings. The study aimed to evaluate CPPS in predicting mortality and amputation in patients undergoing elective revascularization procedures in chronic limb-threatening ischemia (CLTI) patients. METHODS: This is a 2-year retrospective single-center study. We included all patients undergoing elective lower-limb revascularization procedures admitted with CLTI diagnosis. Four CPPS groups were defined: mild, moderate, severe, and morbid. The primary early and long-term outcomes were 30-day overall mortality, 30-day amputation rate, and overall survival and limb salvage, respectively. RESULTS: A total of 442 patients were enrolled in the study. Mean age was 76.5 ± 9.9 years, and 61.5% (272/442) were male. CPPS was calculated: 22.6% (100/442) have mild CPPS, 54.3% (240/442) moderate, 21.9% (97/442) severe, and 1.2% (5/442) morbid. Kaplan-Meier curves for overall survival stratified by CPPS grade highlighted a strong statistically significant difference (P < 0.0001) among the 4 CPPS classes. Mild CPPS has a significantly higher limb salvage rate among moderate, severe, and morbid CPPS groups (P < 0.0001). Limb salvage for mild and severe CPPS, at 36 months was 95% vs. 85.1%, respectively. Stepwise multivariable Cox-analysis revealed that mortality was independently associated with dialysis, Rutherford Classification V, age, and CPPS. Male sex, multilevel arterial disease, and hybrid surgical repair were independently associated with amputations. CONCLUSIONS: CPPS is a straightforward tool to evaluate the patient's complexity and could be used as an adjuvant tool to stratify early- and long-term outcomes in CLTI patients undergoing elective revascularization procedures.

Medication-related problems among patients with cervical cancers at oncology centers of University of Gondar comprehensive specialized hospital: A hospital-based retrospective study.

INTRODUCTION: Though drugs play indispensable role in the treatment of cervical cancer, they are associated with medication-related problems (MRPs). Hence, the present study was aimed to investigate MRPs among patients with cervical cancer. METHODS: A hospital-based retrospective study was employed at the oncology center of University of Gondar Comprehensive Specialized Hospital. All patients with cervical cancer diagnosis from January 1, 2016 to December 31, 2020, were included. Stata version 16/MP for Windows was used for description and analysis. Logistic regression analysis was employed. RESULTS: A total of 124 patients with cervical cancer were included. Paclitaxel and cisplatin (69.4%) combination were the most widely used treatment regimen. MRPs were found in 59.7% patients, with a mean of 2.22 ± 1.13. Subtherapeutic dose (24.4%), the need for additional drug therapy (22.6%), and adverse drug reactions (22%) were the most prevalent MRPs. Being >50 years (adjusted odds ratio (AOR) = 15.37, 95% confidence interval (CI) = 2.25-105.09, p = 0.005), treated with ≥5 medications (AOR = 7.00, 95% CI = 2.65-18.49, p < 0.001), and being stage III (AOR = 15.43, 95% CI = 2.92-81.47, p = 0.001) and stage IV (AOR = 8.41, 95% CI = 1.35-52.44, p = 0.023) were independent predictors of MRPs. CONCLUSION: More than half of patients with cervical cancer had one or more MRPs. Being older, patients taking polypharmacy, stage III and IV patients were significantly associated with the development of MRPs. As most of the cervical patients experienced one or more MRPs, clinical pharmacy service should be strengthened to optimize drug therapy to reduce unwanted adverse events.

Factors associated with potentially inappropriate medications in elderly with multiple myeloma.

INTRODUCTION: Elderly with cancer often have multimorbidity, which determines a higher risk of polypharmacy. This is related to negative clinical results such as adverse drug reaction and emergence service visits. Furthermore, polypharmacy increases the risk of using potentially inappropriate medications. OBJECTIVE: To evaluate the use of potentially inappropriate medication in elderly with multiple myeloma and associated factors. METHODS: The study was conducted with older adults with multiple myeloma treated at outpatient oncology and hematology services in a southeastern Brazilian capital. Potentially inappropriate medications were classified using the American Geriatric Society/Beers 2019 Criteria. Variables were described using frequency and proportions, performing multiple logistic regression to identify factors associated with the use of potentially inappropriate medications. RESULTS: One hundred fifty-three older adults with multiple myeloma were included, with a median age of 70.9 years. The median number of medications was 8, and 63% of patients used polypharmacy. More than half (54%) of the patients used potentially inappropriate medications, and proton pump inhibitors (46%) and benzodiazepines (8%) were the most employed therapeutic classes. Older adults who used potentially inappropriate medications differed from those who did not use them in the following characteristics: income up to three minimum wages, higher schooling level, private service, multimorbidity, hypertension, cardiovascular disease, chronic kidney disease, depression, adverse event, and polypharmacy. Higher schooling levels and polypharmacy were independently associated with the use of potentially inappropriate medications in the multivariate analysis. CONCLUSION: Potentially inappropriate medication use was high in patients with multiple myeloma studied. The use of polypharmacy and higher schooling levels were independently and positively associated with the use of potentially inappropriate medications.

Multimorbidity as chronic crisis: 'Living on' with multiple long-term health conditions in a socially disadvantaged London borough.

Contemporary health services are primarily designed around single diseases. People with multimorbidity (multiple long-term health conditions) often become burdened by accumulated treatments. Through multimodal fieldwork in a socially disadvantaged London borough, we explore how people living with multimorbidity navigate conditions of 'chronic crisis', encompassing ill-health, overmedicalisation, polypharmacy and social exclusion. Participants in our study frequently experience 'existential stuckness', exacerbated by processes of social exclusion. We argue that diagnoses and treatments should account for people's unique aetiologies, and prioritise the notion of 'flourishing' over 'cure' as the absence of disease is not always achievable. To foster this emphasis on flourishing, we advocate for a dialogical turn in diagnostic processes that better support patients' existential needs in the context of long-term illness.

The relationship between hyperpolypharmacy and one-year outcomes in patients with critical limb ischemia undergoing below-knee endovascular therapy.

BACKGROUND: Critical limb ischemia (CLI) patients take too many medications because they are elderly and frail patients with multiple comorbidities. Polypharmacy is associated with frailty, although its prognostic significance in CLI patients is unknown. In this study, we aimed to determine the prevalence of hyperpolypharmacy among adults with CLI and its effect on 1-year amputation and mortality. METHODS: A total of 200 patients with CLI who underwent endovascular therapy (EVT) for below-knee (CTC) lesions were included in this study. Hyperpolypharmacy was defined as using ≥10 drugs. Patients were divided into two groups according to the presence of hyperpolypharmacy. RESULTS: We detected hyperpolypharmacy in 66 patients. The incidence of 1-year amputation [24 (36.4) versus 12 (9), p<.001] and mortality [28 (42.4) versus 12 (9), p<.001] were higher in patients with hyperpolypharmacy. Univariate and multivariate cox regression analyses were used to determine the independent predictors of amputation and mortality. In the receiver operating characteristic curve analysis, the cut-off value was defined as 10 or more drug use was able to detect the presence of 1-year mortality with 67.5% sensitivity and 79.4% specificity. The Kaplan-Meier method showed a significant difference (rank p <.001 between log groups), and hyperpolypharmacy was associated with 1-year amputation and mortality. CONCLUSION: Hyperpolypharmacy was significantly associated with 1-year mortality and major amputation in CLI patients. Hyperpolypharmacy can be a valuable aid in patient risk assessment in the CLI.

When cardiovascular medicines should be discontinued.

An integral component of the practice of medicine is focused on the initiation of medications, based on clinical practice guidelines and underlying trial evidence, which usually test the addition of novel medications intended for life-long use in short-term clinical trials. Much less attention is given to the question of medication discontinuation, especially after a lengthy period of treatment, during which patients age gets older and diseases may either progress or new diseases may emerge. Given the paucity of data, clinical practice guidelines offer little to no guidance on when and how to deprescribe cardiovascular medications. Such decisions are often left to the discretion of clinicians, who, together with their patients, express concern of potential adverse effects of medication discontinuation. Even in the absence of adverse effects, the continuation of medications without any proven effect may cause harm due to drug-drug interactions, the emergence of polypharmacy, and additional preventable spending to already strained health systems. Herein, several cardiovascular medications or medication classes are discussed that in the opinion of this author group should generally be discontinued, either for the prevention of potential harm, for a lack of benefit, or for the availability of better alternatives.

Pharmacist-driven deprescribing initiative in primary care.

BACKGROUND: Polypharmacy, a broad term to describe the use of numerous and often unnecessary medications, has been connected to frailty, hospital admissions, falls, and even mortality. The Veterans Health Administration (VHA) developed the VIONE (vital, important, optional, not indicated, and every medication has an indication) dashboard to identify patients with polypharmacy and serve as a framework for deprescribing of medications across VHA facilities where it is used in a variety of practice settings by different disciplines. OBJECTIVE: This study aimed to describe the implementation of a pharmacist-led, system-wide, deprescribing initiative in the primary care setting. PRACTICE DESCRIPTION: Interdisciplinary education was provided through academic detailing. Subsequently, patients were identified for inclusion in the project using the VIONE dashboard focusing on those at highest risk of polypharmacy and moving down to the lowest risk. Interested patients underwent a medication reconciliation. A clinical pharmacist practitioner (CPP) then contacted the patient to discuss potential deprescribing options. Recommendations were relayed to the primary care provider (PCP) for final approval and communicated to the patient by the pharmacy team. PRACTICE INNOVATION: Primary care CPPs (n = 3) integrated deprescribing into their standard workload. This service was implemented in the primary care setting across an entire health care system consisting of 16 different primary care teams. EVALUATION METHODS: The initiative's impact was measured by the number of discontinued medications, the acceptance rate of recommendations by the PCP, the potential annualized cost avoidance, and the number of patients referred to CPP medication management clinics. RESULTS: Among 63 patients, a total of 352 medications were deprescribed resulting in a potential annualized cost avoidance of $184,221. The acceptance rate of discontinuation recommendations was 96.7%. Subsequently, 25.4% of patients were referred to pharmacist-led clinics for disease state management. CONCLUSION: Embedding deprescribing into standard CPP workflow within the primary care setting facilitated a way for polypharmacy reduction and allowed the expansion of pharmacy-led services at VA Butler Healthcare System.

Patterns of psychotropic medication prescribing and potential drug-hormone interactions among transgender and gender-diverse adults within 2 years of hormone therapy.

BACKGROUND: Transgender and gender-diverse (TGD) people have a high prevalence of psychotropic medication use, yet knowledge about the patient-level psychotropic medication burden is limited. TGD patients may take hormone therapy to meet their gender expression goals. Potential drug-hormone interactions exist between psychotropic medications and hormone therapy, requiring increased knowledge about psychotropic medication use for TGD adults undergoing hormone therapy. OBJECTIVES: The objective of this study was to examine the extent of psychotropic medication polypharmacy in a cohort of TGD adults within 2 years of starting hormone therapy. We also characterized potential drug-hormone interactions and the association with psychotropic polypharmacy. METHODS: Retrospective cross-sectional analysis of patients with ≥1 transgender health-related visit (2007-2017) in the University of Washington Medical System (Seattle, WA). Eligible patients had ≥1 psychotropic medication including antidepressants, antipsychotics, mood stabilizers, and sedative-hypnotics ordered within 2 years of starting hormone therapy (testosterone or estradiol with or without spironolactone, progesterone, finasteride, or dutasteride). We defined psychotropic polypharmacy as ≥2 psychotropic medication orders with overlapping treatment durations for at least 90 days and characterized potential drug-hormone interactions (Lexicomp, Hudson, OH). We descriptively summarized patients with and without polypharmacy (frequencies and percentages) and compared drug-hormone interactions using chi-square or Fishers exact tests (P < 0.05 considered significant). RESULTS: A total of 184 patients had ≥1 psychotropic medication order within 2 years of hormone therapy; 68 patients (37.0%) had psychotropic polypharmacy. The most frequent type of psychotropic polypharmacy was antidepressant+sedative-hypnotic (18 of 68, 26.5%). More patients had a potential drug-hormone interaction among those with psychotropic polypharmacy (23 of 68, 33.8%) versus those without (8 of 116, 6.9%, P < 0.001). CONCLUSION: Among TGD patients on psychotropic medications within 2 years of hormone therapy, one-third had psychotropic polypharmacy. Most polypharmacy types appeared to align with mental health treatment guidelines. The number of patients with a potential drug-hormone interaction was significantly higher among those with polypharmacy. Prospective studies are needed to characterize drug-hormone interactions.

Characteristics of clinical-pharmacological recommendations in psychiatry in Germany.

OBJECTIVE: Psychiatric patients in general, and elderly psychiatric patients in particular, are at risk of adverse drug reactions due to comorbidities and inappropriate polypharmacy. Interdisciplinary and clinical-pharmacologist-led medication reviews may contribute to medication safety in the field of psychiatry. In this study, we reported the frequency and characteristics of clinical-pharmacological recommendations in psychiatry, with a particular focus on geriatric psychiatry. METHOD: A clinical pharmacologist, in collaboration with the attending psychiatrists and a consulting neurologist, conducted interdisciplinary medication reviews in a general psychiatric ward with a geropsychiatric focus at a university hospital over a 25-week period. All clinical and pharmacological recommendations were recorded and evaluated. RESULTS: A total of 316 recommendations were made during 374 medication reviews. Indications/contraindications of drugs were the most frequently discussed topics (59/316; 18.7 %), followed by dose reductions (37/316; 11.7 %), and temporary or permanent discontinuation of medications (36/316; 11.4 %). The most frequent recommendations for dose reduction involvedbenzodiazepines (9/37; 24.3 %). An unclear or absent indication was the most common reason for recommending temporary or permanent discontinuation of the medication (6/36; 16.7 %). CONCLUSION: Interdisciplinary clinical pharmacologist-led medication reviews represented a valuable contribution to medication management in psychiatric patients, particularly the elderly ones.
