Polypharmacy is a risk factor for hospital admission due to a fall: evidence from the English Longitudinal Study of Ageing

Medication Profiles at Hospital Discharge Predict Poor Outcomes After Acute Ischemic Stroke

Objectives: To examine the relationship between medications prescribed during the first 6-months post-stroke and functional outcome. Materials and Methods: A retrospective analysis of ischemic stroke survivors enrolled in an observational stroke recovery study from June-2017 to July-2019 was performed. Survivors with favorable outcomes (modified rankin scale (mRS) score 0-2) were compared to those with unfavorable outcomes (mRS ≥3) 6-months after stroke on the following: discharge medication classes prescribed, achievement of recommended targets for blood pressure control, glycemic control, and LDL ≤70 mg/dL, medication changes, medication interactions, and medication list discrepancies. Results: Unfavorable 6-month outcomes occurred in 36/78 (46.2%) of survivors. Survivors with unfavorable outcomes were more likely to be prescribed a central nervous system-acting agent (97.2% vs 71.4%; P = .0022) and/or an anti-hyperglycemic agent (25.0% vs 9.5%; P = .009) at discharge. After adjustment of baseline covariates, total number of medications prescribed was associated with unfavorable 6-month outcomes (OR 1.13, 95% CI 1.0-1.28). Secondary stroke prevention measures were not achieved in a high proportion of survivors. Medication changes during 6-month follow up were common and survivors with unfavorable outcomes were more likely to have clinically significant drug-drug interactions. Discussion: At 6-months, survivors with unfavorable outcomes were found to be prescribed more medications, particularly central nervous system-acting and anti-hyperglycemic agents. There were also more drug-drug interactions in the medications prescribed compared to those with favorable outcomes. Together, these data suggest the need for enhanced screening of high-risk stroke survivors focused on close monitoring of polypharmacy, drug-drug interactions, and adverse events with pharmacotherapy.

CVD incidence and mortality among people with diabetes and/or hypertension: Results from the English longitudinal study of ageing

BACKGROUND AND AIMS

Diabetes and/or hypertension are the most common conditions in older people, and also related to higher cardiovascular disease (CVD) incidence and mortality. This study aims to explore the risk of CVD incidence and mortality among older people with diabetes and/or hypertension over a 16 years follow-up period and investigates the role of depression and obesity in these relationships.

METHODS

6,855 participants aged 50+ from the English Longitudinal Study of Ageing (ELSA). The main exposure is having diabetes and/or hypertension at baseline (2002/2003) compared to not having, but excluded those with coronary heart disease (CHD) and/or stroke (CVD). Survival models are used for CVD incidence and mortality up to 2018, adjusted for socio-demographic, health, health behaviours, cognitive function, and physical function characteristics.

RESULTS

39.3% of people at baseline had diabetes and/or hypertension. The risk of CVD incidence was 1.7 (95%CI: 1.5; 1.9) higher among people with diabetes and/or hypertension compared to those without and was independent of covariates adjustment. People with diabetes and/or hypertension were also 1.3 (95%CI: 1.1; 1.8) times more likely to die from CVD than those without. We did not find evidence for an elevated risk of CVD incidence and mortality among people with obesity nor among those with depression.

CONCLUSIONS

In order to effectively reduce the risk of CVD incidence and mortality among older people, treatment as well as management of hypertension and diabetes should be routinely considered for older people with diabetes and/or hypertension.

Long-term trends in mortality from adverse effects of medical treatment in older populations in the United States from 1990 to 2019

BACKGROUND

Adverse Effects of Medical Treatment (AEMT) refer to unintended harm caused by medical care and are a significant public health concern.

OBJECTIVE

This study utilizes the Global Burden of Disease database to investigate AEMT mortality trends among older adults in the United States from 1990 to 2019, focusing on crude mortality rates and age-standardized mortality rate trends by age group and sex.

METHODS

The study employs cause-of-death ensemble modeling and statistical analysis to examine crude and age-standardized mortality rates (ASRs) for AEMT in older age groups and identify trends in mortality due to AEMTs in those over 65 years of age in the United States. Trends in the ASR of AEMT were analyzed using the Joinpoint regression model.

RESULTS

AEMT mortality rates increased among older adults from 2012 to 2019, with the highest increase observed in the 95 years or older age group. Significant differences were noted in AEMT mortality rates between older men and women, with older men having higher rates and showing an upward trend, while rates among older women decreased from 1990 to 2019.

CONCLUSION

The study highlights an overall increase in ASR related to AEMT among older adults in the United States, with men shown to have a greater susceptibility to death from AEMT. Increased attention toward the detrimental impact of AEMT on our aging population, particularly for men, in conjunction with reinforcement of health policies and education, is warranted.

Involvement of Older Adults, the Golden Resources, as a Primary Measure for Fall Prevention

Falls remain the second leading cause of injury-related deaths worldwide; therefore, longstanding practical fall-prevention efforts are needed. Falls can also lead to a reduction in independence and quality of life among older adults. Fall-prevention research has found that early prevention promotes a prolonged independence. However, it remains unknown which intervention is most beneficial for early prevention and how these interventions should be implemented for long-term effects. In addition, the present and future burden on social and healthcare services contributes to a gap in needs and requires an evidence-based fall prevention. Research suggests that strength, balance, and functional training are effective in reducing falls and fall-related injuries. Such training could greatly impacting independence. Fear of falling and strategies for managing falls are the suggested components to be included when evaluating fall-prevention programs. Thus, the preservation of physical functions is highly relevant for both independence and quality of life. It also contributes to psychological and social well-being, which are important factors for enabling individuals to stay at home for as long as possible. To meet future challenges associated with the expected increase in the older population, older adults should be viewed as a golden resource. With assistance from professionals and researchers, they can learn and gain the ability to institute fall-prevention programs in their own environments. These environments are primarily beyond the responsibilities of the healthcare sector. Therefore, programs comprising current knowledge about fall prevention should be developed, evaluated, and implemented with older adults by using a "train-The-trainer" approach, where a natural collaboration is established between civil society and/or volunteers, healthcare professionals, and researchers. For sustainable and effective fall-prevention programs, a co-design and early collaborative approach should be used in the natural environment, before social and healthcare services are required.

Drug-Related Problems in Elderly Patients Attended to by Emergency Services

The progressive aging and comorbidities of the population have led to an increase in the number of patients with polypharmacy attended to in the emergency department. Drug-related problems (DRPs) have become a major cause of admission to these units, as well as a high rate of short-term readmissions. Anticoagulants, antibiotics, antidiabetics, and opioids have been shown to be the most common drugs involved in this issue. Inappropriate polypharmacy has been pointed out as one of the major causes of these emergency visits. Different ways of conducting chronic medication reviews at discharge, primary care coordination, and phone contact with patients at discharge have been shown to reduce new hospitalizations and new emergency room visits due to DRPs, and they are key elements for improving the quality of care provided by emergency services.

Effect of polypharmacy and Fall-Risk-Increasing Drugs (FRIDs) on falls among Brazilian older adults: The SABE cohort study

Polypharmacy, considered as the use of multiple medications, has been one of the factors associated with a higher risk of falls among older adults. However, the association of this factor regardless of the use of Fall-Risk-Increasing Drugs (FRIDs) has not been extensively explored.

OBJECTIVES

This study aimed to evaluate the longitudinal association of polypharmacy with falls and verify whether this association is independent of FRID use.

METHODS

A longitudinal study was conducted with a representative sample of the urban population aged 60 years and over in the city of São Paulo, Brazil, from 2000 to 2006. The analysis of the association among polypharmacy, the use of FRIDs, and the occurrence of falls over the years was performed using Generalized Estimating Equation (GEE) models adjusted for covariates.

RESULTS

The association between polypharmacy and falls was significantly attenuated after the adjustment for covariates and FRIDs. Users of two or more FRIDs had higher odds of falls (OR = 1.51; CI [1.16; 1.96]).

CONCLUSION

FRID use was associated with the occurrence of falls among older adults. The number of medications must be kept to the minimum necessary, and FRIDs should be avoided in approaches to preventing falls among older adults.

Control Level of Type 2 Diabetes Mellitus in the Elderly Is Associated with Polypharmacy, Accompanied Comorbidities, and Various Increased Risks According to the Beers Criteria

Comorbidity rates in the geriatric population have increased because of rising life expectancy; thus, patients have had to use more medications. Type 2 diabetes mellitus, one of the most common diseases, may influence the number of drugs used in geriatric patients. The present study was designed to investigate the association between the level of type 2 DM and polypharmacy. Fifty patients with type 2 diabetes over the age of 65 were included according to the inclusion criteria; 23 were well-controlled and 27 had poorly controlled diabetes. The groups were similar in terms of age, sex, WBC, Hb, Plt, AST, ALT, serum creatinine, fasting glucose, and eGFR levels. Patients with HbA1c values above 7.5 were classified as poorly controlled diabetes patients, and those below were considered well-controlled diabetes patients and were evaluated for inappropriate medication use. The number of medications used daily by the cases (p < 0.001), the number of concomitant diseases (p = 0.001), and the number of increased risks according to the Beers Criteria (p = 0.02) were observed to be high in poorly controlled type 2 diabetes mellitus subjects. HbA1c levels were related to the number of medications (r = 0.4, p = 0.004), comorbidities (r = 0.28, p = 0.04), and the number of increased risks according to the Beers Criteria (r = 0.31, p = 0.014). In conclusion, the number of medications used in patients with poorly controlled type 2 diabetes mellitus was found to be more elevated than in individuals with well-controlled type 2 diabetes mellitus. The HbA1c values varied among patients regarding polypharmacy, comorbidities, and increased risks according to the Beers Criteria.

Assessing medication-related burden of community-dwelling individuals with chronic conditions in a small island state

OBJECTIVES

Medication taking in the management of chronic conditions causes a significant burden on individuals. The aim of this study was to explore the medication-related burden in ambulatory adult patients with chronic conditions in Malta.

METHODS

A cross-sectional survey utilising the living with medicines questionnaire V3 (LMQ V3) was conducted in Maltese residents over the age of 18 years, taking at least 1 medication for a chronic condition and recruited through community events. The overall LMQ score, the domain scores and the visual analog scale data were analysed to determine relationships with the demographic factors.

RESULTS

A total of 337 responses were analysed revealing a moderate (42.4%) to high medication (36.8%) related burden. The drivers of medication-related burden were primarily: 'side-effects of prescribed medication' (r = -0.843, p < 0.001), 'attitudes/concerns about medicine use' (r = -0.830, p < 0.001) and 'impact/interferences to day-to-day life' (r = -0.820, p < 0.001). Lack of autonomy to vary the dosage regimen resulted in a higher burden (r = -0.260, p < 0.001). Males experienced an overall higher burden (p = 0.046) especially related to practical difficulties (p = 0.04), cost-related burden (p = 0.04) and side-effects of prescribed medication (p = 0.01).

CONCLUSION

Medication-related burden is complex and multi-faceted as demonstrated by the findings of this study. Healthcare professionals should seek to identify and address factors causing this burden to improve patient outcomes.

Impact of deprescribing intervention on potentially inappropriate medications and clinical outcomes among hospitalized older adults in Malaysia: a randomized controlled trial (REVMED RCT) protocol

BACKGROUND

Polypharmacy and the use of potentially inappropriate medications (PIMs) are prevalent among older patients admitted to hospitals, posing a heightened risk of adverse drug events. This trial aims to evaluate the effectiveness of a pharmacist-led deprescribing intervention in reducing medications, PIM and improving clinical outcomes, using the locally developed Malaysian Potentially Inappropriate Prescribing Screening tool in Older Adults (MALPIP).

METHODS

This is an 18-month cluster-randomized, open-label, parallel-arm controlled trial conducted at 14 public hospitals in the Perak state of Malaysia. Patients aged 60 and above, who have at least one medication and one comorbidity are eligible. A stratified-cluster randomization design is employed, with 7 hospitals assigned to the control arm and 7 hospitals assigned to the intervention arm. The MALPIP screening tool will be used in the intervention group to review the medications. If PIM is detected, the pharmacists will discuss with doctors and decide whether to stop or reduce the dose. The primary outcomes of this trial are the total number of medications and number of PIM. The secondary outcomes include fall, emergency department visits, readmissions, quality of life and mortality. Outcomes will be measured during enrolment, discharge, 6, 12, and 18 months.

DISCUSSION

This REVMED trial aims to test the hypothesis that a pharmacist-led deprescribing intervention initiated in the hospital will reduce the total number of medications and PIM 18 months after hospital discharge, reducing fall, emergency department visits, readmissions, mortality and lead to improvement in quality of life. Trial findings will quantify the clinical outcomes associated with reducing medications and PIM for hospitalized older adults with polypharmacy.

TRIAL REGISTRATION NUMBER

This trial was prospectively registered at clinicaltrials.gov (NCT05875623) on the 25th of May 2023. NCT05875623 Clinicaltrials.gov URL: NCT05875623 registered on 25th July 2023.

Association of Primary Care Risk Mitigation Visits and Nonelective Emergency Department Visits in Patients Using Long-term Opioid Therapy

Objective

To determine risk factors for nonelective emergency department visits (NEDVs) and whether primary care visits incorporating risk mitigation tools prevented NEDVs among patients using long-term opioid therapy (LOT).

Patients and Methods

We retrospectively searched the electronic health records at Mayo Clinic primary care outpatient practices in Arizona and Florida in all of 2018 and 2019 for the records of individual adult patients using LOT. Patient and clinician demographic characteristics and patient risk factors were compared between patients with and without risk mitigation visits. Univariate and multivariable logistic regression was used to determine risk factors for NEDVs.

Results

Among 457 patients using LOT identified during the study period, most were women (n=266, 58.2%), and the median age was 69 years. Long-term opioid therapy risk mitigation visits were performed equally by family medicine and internal medicine clinicians and by a significantly higher proportion of Florida clinicians than Arizona clinicians (87.0% vs 70.5%; P<.001). Older age, falls, and mental health care utilization all increased the risk of NEDVs. Risk mitigation visits were protective against NEDVs (odds ratio, 0.56; 95% CI, 0.35-0.89; P=.01) after adjustment for older age, falls, and mental health care utilization.

Conclusion

Risk mitigation visits are effective in preventing NEDVs, and all patients using LOT should have such visits when possible.

Fall-related Injuries and Opioid Administration Among Veterans With Dementia in US Department of Veterans Affairs Community Living Centers

OBJECTIVES

Opioid use is associated with fall-related injuries (FRI) among older adults, especially those with dementia. We examined FRI following changes in national opioid safety initiatives over 3 regulatory periods [preinitiatives baseline (period 1): October 2012 to June 2013; post-Veteran Affairs (VA) opioid safety initiative (period 2): January 2014 to November 2015; post-VA and CDC opioid prescribing guidelines (period 3): March 2017 to September 2018] among Department of VA Community Living Center (CLC) long-stay residents with dementia.

DATA

VA provided and purchased care records, Medicare claims, CLC Minimum Data Set (MDS) assessments. VA bar-code medication administration data, VA outpatient prescription refill data, and Medicare Part D data were used to capture medication from inpatient, outpatient, and Medicare sources.

SETTINGS AND PARTICIPANTS

A total of 12,229 long-stay CLC residents with dementia between October 2012 and September 2018.

METHODS

We applied Veteran-regulatory period level (1) generalized linear model to examine the unadjusted and adjusted trends of FRI, and (2) difference-in-difference model with propensity score weighting to examine the relationship between opioid safety initiatives and FRI in 3 regulatory periods. We applied propensity score weighting to enable the cohorts in periods 2 and 3 had similar indications for opioid administration as in period 1.

RESULTS

FRI prevalence per month among CLC residents with Alzheimer disease and related dementias decreased from 3.1% in period 1 to 1.6% and 1.2% in periods 2 and 3, and the adjusted probability of FRI was 17% and 40% lower in periods 2 and 3 compared with period 1. The any, incident, and continued opioid administration were significantly associated with higher FRI, whereas the differences in FRI probabilities between opioid and nonopioid users had no significant changes over the 3 regulatory periods.

CONCLUSIONS

FRI was reduced among CLC residents with Alzheimer disease and related dementias receiving care in VA CLCs over the 3 regulatory periods, but the FRI reduction was not significantly associated with opioid safety initiatives. Other interventions that potentially targeted falls are likely to have helped reduce these fall events. Future studies could examine whether opioid use reduction ultimately benefitted nursing home residents by focusing on other possible outcomes or whether such reduction only resulted in more untreated pain.

Management of Older Adults with Sickle Cell Disease: Considerations for Current and Emerging Therapies

People with sickle cell disease (SCD) are living longer than ever before, with the median survival increasing from age 14 years in 1973, beyond age 40 years in the 1990s, and as high as 61 years in recent cohorts from academic centers. Improvements in survival have been attributed to initiatives, such as newborn screening, penicillin prophylaxis, vaccination against encapsulated organisms, better detection and treatment of splenic sequestration, and improved transfusion support. There are an estimated 100,000 people living with SCD in the United States and millions of people with SCD globally. Given that the number of older adults with SCD will likely continue to increase as survival improves, better evidence on how to manage this population is needed. When managing older adults with SCD (defined herein as age ≥ 40 years), healthcare providers should consider the potential pitfalls of extrapolating evidence from existing studies on current and emerging therapies that have typically been conducted with participants at mean ages far below 40 years. Older adults with SCD have historically had little to no representation in clinical trials; therefore, more guidance is needed on how to use current and emerging therapies in this population. This article summarizes the available evidence for managing older adults with SCD and discusses potential challenges to using approved and emerging drugs in this population.

Development of a project for interprofessional collaboration between medical and pharmacy students to improve medication safety in polypharmacy (PILLE)

AIM

Interprofessional collaboration is particularly relevant to patient safety in outpatient care with polypharmacy. The educational project "PILLE" is meant to give medical and pharmacy students an understanding of the roles and competencies needed for cooperation in the provision of healthcare and to enable interprofessional learning.

METHOD

The curriculum is aimed at pharmacy and medical students and was developed in six steps according to the Kern cycle. It is comprised of an interprofessional seminar, a joint practical training in a simulated pharmacy, and a tandem job shadowing at a primary care practice. The project was implemented in three stages due to the pandemic: The interprofessional online seminar based on the ICAP model and the digital inverted classroom was held in the 2020 winter semester; the interprofessional practical training was added in the 2021 summer semester; and the interprofessional tandem job shadowing at a primary care practice in the 2021 winter semester. Attitudes toward interprofessional learning, among other things, was measured in the evaluation using the SPICE-2D questionnaire (Student Perceptions of Physician-Pharmacist Interprofessional Clinical Education).

RESULTS

In the first three semesters, a total of 105 students (46 pharmacy, 59 medicine) participated in the project, of which 78 participated in the evaluation (74% response rate). The students stated, in particular, that they had learned about the competencies and roles of the other profession and desired additional and more specific preparatory materials for the course sessions. The SPICE-2D questionnaire showed high values for both groups of students already in the pre-survey and these increased further as a result of the project.

CONCLUSION

Joint case-based learning could be implemented under the conditions imposed by the pandemic. Online teaching is a low-threshold means to enable interprofessional exchange.

Psychiatric and non-psychiatric polypharmacy among older adults with schizophrenia: Trends from a population-based study between 2000 and 2016

Background: Schizophrenia is a severe psychiatric disorder associated with multiple psychiatric and non-psychiatric comorbidities. As adults with schizophrenia age, they may use many medications, i.e., have polypharmacy. While psychiatric polypharmacy is well documented, little is known about trends and patterns of global polypharmacy. This study aimed to draw a portrait of polypharmacy among older adults with schizophrenia from 2000 to 2016. Methods: This population-based cohort study was conducted using the data of the Quebec Integrated Chronic Disease Surveillance System of the National Institute of Public Health of Quebec to characterize recent trends and patterns of medication use according to age and sex. We identified all Quebec residents over 65 years with an ICD-9 or ICD-10 diagnosis of schizophrenia between 2000 and 2016. We calculated the total number of medications used by every individual each year and the age-standardized proportion of individuals with polypharmacy, as defined by the usage of 5+, 10+, 15+, and 20+ different medications yearly. We identified the clinical and socio-demographic factors associated with polypharmacy using robust Poisson regression models considering the correlation of the responses between subjects and analyzed trends in the prevalence of different degrees of polypharmacy. Results: From 2000 to 2016, the median number of medications consumed yearly rose from 8 in 2000 to 11 in 2016. The age-standardized proportion of people exposed to different degrees of polypharmacy also increased from 2000 to 2016: 5+ drugs: 76.6%-89.3%; 10+ drugs: 36.9%-62.2%; 15+: 13.3%-34.4%; 20+: 3.9%-14.4%. Non-antipsychotic drugs essentially drove the rise in polypharmacy since the number of antipsychotics remained stable (mean number of antipsychotics consumed: 1.51 in 2000 vs. 1.67 in 2016). In the multivariate regression, one of the main clinically significant factor associated with polypharmacy was the number of comorbidities (e.g., Polypharmacy-10+: RR_{[2 VS. 0-1]} = 1.4; 99% IC:1.3-1.4, RR_[3-4] = 1.7 (1.7-1.8); RR_[5+] = 2.1 (2.1-2.2); Polypharmacy-15+: RR_{[2 VS 0-1]} = 1.6; 99% IC:1.5-1.7, RR_[3-4] = 2.5 (2.3-2.7); RR_[5+] = 4.1 (3.8-4.5). Conclusion: There was a noticeable increase in polypharmacy exposure among older adults with schizophrenia in recent years, mainly driven by non-antipsychotic medications. This raises concerns about the growing risks for adverse effects and drug-drug interactions in this vulnerable population.

Factors related to polypharmacy and hyper-polypharmacy for the elderly: A nationwide cohort study using National Health Insurance data in South Korea

Polypharmacy may cause adverse health outcomes in the elderly. This study examined the prevalence of continuous polypharmacy and hyper-polypharmacy, factors associated with polypharmacy, and the most frequently prescribed medications among older adults in South Korea. This was a retrospective observational study using National Health Insurance claims data. In total, 7,358,953 Korean elderly patients aged 65 years and older were included. Continuous polypharmacy and hyper-polypharmacy were defined as the use of ≥5 and ≥10 medications, respectively, for both ≥90 days and ≥180 days within 1 year. A multivariate logistic regression analysis was conducted with adjustment for general characteristics (sex, age, insurance type), comorbidities (12 diseases, number of comorbidities, and Elixhauser Comorbidity Index [ECI] classification), and healthcare service utilization. Among 7.36 million elderly patients, 47.8% and 36.9% had polypharmacy for ≥90 and ≥180 days, and 11.9% and 7.1% of patients exhibited hyper-polypharmacy for ≥90 and ≥180 days, respectively. Male sex, older age, insurance, comorbidities (cardio-cerebrovascular disease, diabetes mellitus, depressive disorder, dementia, an ECI score of ≥3), and healthcare service utilization were associated with an increased probability of polypharmacy. The therapeutic class with the most prescriptions was drugs for acid-related disorders (ATC A02). The number of outpatient visit days more strongly influenced polypharmacy than hospitalizations and ED visits. This study provides health policymakers with important evidence about the critical need to reduce polypharmacy among older adults.

Cross-sectional study on prevalence and risk factors for falls among the elderly in communities of Guangdong province, China

OBJECTIVE

This study aims to investigate the prevalence and risk factors of falls among the elderly in Guangdong, China.

METHODS

A cross-sectional study was conducted in six communities of Guangdong province. People over 60 years old were selected with multistage random-cluster sampling. Data on falls within the previous 12 months and fall-related risk factors were collected through a face-to-face interview.

RESULTS

The prevalence of falls among older adults was 11.9% (95% CI: 11.0% to 12.8%) among 5374 interviewees. The common injuries caused by falls were bruises/scrapes (40.0%) and fractures (15.5%), and most people fall while doing housework (35.0%). Univariate analysis showed that 14 factors were associated with falls among older adults, including gender, age, residence, occupation, education level, balance ability, situation of cognition, disease, depression, living arrangement, marital status, the behaviour of exercise, drinking and drug use (p&lt;0.05). Multivariate analysis showed that the associated factors of falls among older adults included woman (OR=1.68, 95% CI: 1.40 to 2.02), age from 70 to 79 years (OR=1.31, 95% CI: 1.09 to 1.58), age over 80 (OR=1.63, 95% CI: 1.25 to 2.13), impaired balance ability (OR=1.45, 95% CI: 1.20 to 1.75), exercise several times per month (OR=1.69, 95% CI: 1.13 to 2.53), polypharmacy (OR=1.54, 95% CI: 1.19 to 2.00), cognition impairment (OR=1.35, 95% CI: 1.08 to 1.69), mild depression (OR=1.89, 95% CI: 1.47 to 2.45) and moderate depression (OR=3.07, 95% CI: 1.99 to 4.73).

CONCLUSIONS

The hazards caused by falls to the elderly in China cannot be ignored. A multidimensional customised fall prevention programme should be considered to reduce the risk of falls among the elderly based on the results above.

Orthostatic hypotension in elderly: Do you measure orthostatic and clinostatic blood pressure?

In this article we highlighted the blood pressure management in elderly patients with orthostatic hypotension.

A model for predicting fall risks of hospitalized elderly in Taiwan-A machine learning approach based on both electronic health records and comprehensive geriatric assessment

Backgrounds

Falls are currently one of the important safety issues of elderly inpatients. Falls can lead to their injury, reduced mobility and comorbidity. In hospitals, it may cause medical disputes and staff guilty feelings and anxiety. We aimed to predict fall risks among hospitalized elderly patients using an approach of artificial intelligence.

Materials and methods

Our working hypothesis was that if hospitalized elderly patients have multiple risk factors, their incidence of falls is higher. Artificial intelligence was then used to predict the incidence of falls of these patients. We enrolled those elderly patients aged >65 years old and were admitted to the geriatric ward during 2018 and 2019, at a single medical center in central Taiwan. We collected 21 physiological and clinical data of these patients from their electronic health records (EHR) with their comprehensive geriatric assessment (CGA). Data included demographic information, vital signs, visual ability, hearing ability, previous medication, and activity of daily living. We separated data from a total of 1,101 patients into 3 datasets: (a) training dataset, (b) testing dataset and (c) validation dataset. To predict incidence of falls, we applied 6 models: (a) Deep neural network (DNN), (b) machine learning algorithm extreme Gradient Boosting (XGBoost), (c) Light Gradient Boosting Machine (LightGBM), (d) Random Forest, (e) Stochastic Gradient Descent (SGD) and (f) logistic regression.

Results

From modeling data of 1,101 elderly patients, we found that machine learning algorithm XGBoost, LightGBM, Random forest, SGD and logistic regression were successfully trained. Finally, machine learning algorithm XGBoost achieved 73.2% accuracy.

Conclusion

This is the first machine-learning based study using both EHR and CGA to predict fall risks of elderly. Multiple risk factors of falls in hospitalized elderly patients can be put into a machine learning model to predict future falls for early planned actions. Future studies should be focused on the model fitting and accuracy of data analysis.

Using conditional inference forests to examine predictive ability for future falls and syncope in older adults: Results from The Irish Longitudinal Study on Ageing

BACKGROUND

The extent to which gait and mobility measures predict falls relative to other risk factors is unclear. This study examined predictive accuracy of over 70 baseline risk factors, including gait and mobility, for future falls and syncope using conditional inference forest models.

METHODS

Data from three waves of The Irish Longitudinal Study on Ageing (TILDA), a population-based study of community-dwelling adults aged ≥50 years were used (n=4,706). Outcome variables were recurrent falls, injurious falls, unexplained falls and syncope occurring over four year follow-up. Predictive accuracy was calculated using 5 fold cross-validation; as there was class imbalance, the algorithm was trained using undersampling of the larger class. Classification rate, area under the receiver operating characteristic curve (AUROC) and area under the precision recall curve (PRAUC) assessed predictive accuracy.

RESULTS

Highest overall accuracy was 69.7% for recurrent falls in 50-64 year olds. AUROC and PRAUC were ≤0.69 and ≤0.39 respectively for all outcomes indicating low predictive accuracy. History of falls, unsteadiness while walking, fear of falling, mobility, medications , mental health and cardiovascular health and function were the most important predictors for most outcomes.

CONCLUSIONS

Conditional inference forest models using over 70 risk factors resulted in low predictive accuracy for future recurrent, injurious and unexplained falls and syncope in community-dwelling adults. Gait and mobility impairments were important predictors of most outcomes but did not discriminate well between fallers and non-fallers. Results highlight the importance of multifactorial risk assessment and intervention and validate key modifiable risk factors for future falls and syncope.

Low health literacy and multiple medications in community-dwelling older adults: a population-based cohort study

OBJECTIVES

Adequate health literacy is important for patients to manage chronic diseases and medications. We examined the association between health literacy and multiple medications in community-dwelling adults aged 50 years and older in England.

DESIGN, SETTINGS AND PARTICIPANTS

We included 6368 community-dwelling people of median age 66 years from the English Longitudinal Study of Ageing. Health literacy was assessed at wave 5 (2010/11) with 4 questions concerning a medication label. Four correct answers were categorised as adequate health literacy, otherwise low. Data on medications were collected at wave 6 (2012/13). To examine the difference in the number of medications between low and adequate health literacy, we used zero-inflated negative binomial regression, estimating odds ratio (OR) for zero medication and incidence rate ratios (IRR) for the number of medications, with 95% CIs. Associations were adjusted for demographic, socioeconomic and health characteristics, smoking and cognitive function. We also stratified the analysis by sex, and age (50-64 and ≥65 years). To be comparable with preceding studies, multinomial regression was fitted using commonly used thresholds of polypharmacy (0 vs 1-4, 5-9, ≥10 medications).

RESULTS

Although low health literacy was associated with a lower likelihood of being medication-free (OR=0.64, 95% CI: 0.45 to 0.91), health literacy was not associated with the number of medications among those at risk for medication (IRR=1.01, 95% CI: 0.96 to 1.05), and this finding did not differ among younger and older age groups or women. Among men, low health literacy showed a weak association (IRR=1.06, 95% CI: 0.99 to 1.14). Multinomial regression models showed graded risks of polypharmacy for low health literacy.

CONCLUSIONS

Although there was no overall association between health literacy and the number of medications, this study does not support the assertion that low health literacy is associated with a notably higher number of medications in men.

The understanding and experience of falls among community-dwelling adults aged 50 and over living with mental illness: A qualitative study

OBJECTIVES

Compared to the general older population, older adults living with mental illness are at greater risk of falling and these risks can be present from middle age. This study aimed to explore the understanding of falls and the experiences community-dwelling adults aged 50 years and over living with mental illness who have had a fall, and to identify any falls prevention strategies valued by them.

METHODS

A qualitative descriptive approach was adopted. Ten adults with past experience of falls were recruited at a community mental health service in Sydney, Australia. Semi-structured interviews were conducted between July and September 2018. Interviews were transcribed verbatim and data were thematically analysed.

RESULTS

Three major themes emerged: (1) making sense of falls, (2) being self-reliant and enduring the consequences of falls, and (3) preventing future falls - perceptions and strategies. Most participants in this study were uncertain about the cause of their falls and seemed to have limited understanding of falls risk factors. They were also less likely to seek help after a fall, despite an injury. Consequences of falls included physical injuries and negative emotional impacts experienced following a fall. Most participants expressed a certain degree of concern regarding future falls, however, their strategy to prevent falls was to simply "be careful."

CONCLUSION

Adults aged over 50 years and living with mental illness in the community need support to identify and manage their falls risk. Fall prevention interventions tailored to the needs of this population are needed.

CRIDECO Anticholinergic Load Scale: An Updated Anticholinergic Burden Scale. Comparison with the ACB Scale in Spanish Individuals with Subjective Memory Complaints

The increase in life expectancy has also been accompanied by an increase in the use of medication to treat chronic diseases. Polypharmacy is associated with medication-related problems such as the increase in the anticholinergic burden. Older people are more susceptible to anticholinergic effects on the central nervous system and this, in turn, may be related to cognitive impairment. In this paper, we develop an updated anticholinergic burden scale, the CRIDECO Anticholinergic Load Scale (CALS) via a systematic review of the literature and compare it with the currently most used Anticholinergic Burden Scale (ACB). Our new scale includes 217 different drugs with anticholinergic properties, 129 more than the ACB. Given the effect that anticholinergic medications have on cognitive performance, we then used both scales to investigate the relationship between anticholinergic burden and cognitive impairment in adult Spanish subjects with subjective memory complaint. In our population, we observed an association between cognitive impairment and the anticholinergic burden when measured by the new CALS, but not when the ACB was applied. The use of a more comprehensive and upgraded scale will allow better discrimination of the risk associated with the use of anticholinergic medications on cognitive impairment. CALS can help raise awareness among clinicians of the problems associated with the use of medications, or combinations of them, with large anticholinergic effect, and promote a better personalized pharmacological approach for each patient.

Persistent polypharmacy and fall injury risk: the Health, Aging and Body Composition Study

BACKGROUND

Older adults receive treatment for fall injuries in both inpatient and outpatient settings. The effect of persistent polypharmacy (i.e. using multiple medications over a long period) on fall injuries is understudied, particularly for outpatient injuries. We examined the association between persistent polypharmacy and treated fall injury risk from inpatient and outpatient settings in community-dwelling older adults.

METHODS

The Health, Aging and Body Composition Study included 1764 community-dwelling adults (age 73.6 ± 2.9 years; 52% women; 38% black) with Medicare Fee-For-Service (FFS) claims at or within 6 months after 1998/99 clinic visit. Incident fall injuries (N = 545 in 4.6 ± 2.9 years) were defined as the initial claim with an ICD-9 fall E-code and non-fracture injury, or fracture code with/without a fall code from 1998/99 clinic visit to 12/31/08. Those without fall injury (N = 1219) were followed for 8.1 ± 2.6 years. Stepwise Cox models of fall injury risk with a time-varying variable for persistent polypharmacy (defined as ≥6 prescription medications at the two most recent consecutive clinic visits) were adjusted for demographics, lifestyle characteristics, chronic conditions, and functional ability. Sensitivity analyses explored if persistent polypharmacy both with and without fall risk increasing drugs (FRID) use were similarly associated with fall injury risk.

RESULTS

Among 1764 participants, 636 (36%) had persistent polypharmacy over the follow-up period, and 1128 (64%) did not. Fall injury incidence was 38 per 1000 person-years. Persistent polypharmacy increased fall injury risk (hazard ratio [HR]: 1.31 [1.06, 1.63]) after adjusting for covariates. Persistent polypharmacy with FRID use was associated with a 48% increase in fall injury risk (95%CI: 1.10, 2.00) vs. those who had non-persistent polypharmacy without FRID use. Risks for persistent polypharmacy without FRID use (HR: 1.22 [0.93, 1.60]) and non-persistent polypharmacy with FRID use (HR: 1.08 [0.77, 1.51]) did not significantly increase compared to non-persistent polypharmacy without FRID use.

CONCLUSIONS

Persistent polypharmacy, particularly combined with FRID use, was associated with increased risk for treated fall injuries from inpatient and outpatient settings. Clinicians may need to consider medication management for FRID and other fall prevention strategies in community-dwelling older adults with persistent polypharmacy to reduce fall injury risk.

Factors associated with falls in hemodialysis patients: a case-control study

OBJECTIVE

to identify possible associations between a higher probability of falls among hemodialysis patients and laboratory values, comorbidities, pharmacological treatment, hemodynamic changes, dialysis results and stabilometric alterations.

METHOD

this was a retrospective case-control study with hemodialysis patients. Patients in a hemodialysis unit who had suffered one or more falls were included in the case group. Patients from the same unit who had not suffered falls were the controls. Data were gathered from the patients' clinical history and also from the results of a balance test conducted six months before the study.

RESULTS

thirty-one patients were included (10 cases and 21 controls). Intradialytic body weight change was significantly greater among cases (p <0.05). Patients in the case group also presented greater lateral instability after dialysis (p <0.05). Other factors such as high blood pressure, antihypertensives, beta-blockers, and lower heart rates were also associated with falls.

CONCLUSION

a greater intradialytic weight change was associated with an increase in risk of falls. Nursing staff can control these factors to prevent the incidence of falls in dialysis patients.

Functional Status among Polymedicated Geriatric Inpatients at Discharge: A Population-Based Hospital Register Analysis

This study explored and compared the functional status of polymedicated and non-polymedicated geriatric inpatients at hospital discharge. We used a cross-sectional registry of geriatric patients' hospital records from a multi-site public hospital center in Switzerland. The analysis included all inpatients aged 65 years old or more admitted between 1 January 2015 and 31 December 2017 (n = 53,690), of whom 67.5% were polymedicated at hospital discharge, 52.1% were women (n = 18,909), and 42.7% were 75-84 years old (n = 15,485). On average, the polymedicated patients' hospital lengths of stay were six days longer, they presented with more than three comorbidities, and they were prescribed more than nine medications at hospital discharge (p < 0.001). They showed more frequent general mobility decline (43.2% vs. 41.9%), gait disorders (46.2% vs. 43%), fatigue (48.6% vs. 43.4%) and dependence on lower-body care (49.7% vs. 47.6%), and presented a higher malnutrition risk (OR = 1.411; 95%CI 1.263-1.577; p < 0.001). However, the non-polymedicated inpatients had proportionally more physical and cognitive impairments. The comparison of the functional status of polymedicated and non-polymedicated geriatric inpatients at hospital discharge is important for clinicians trying to identify and monitor those who are most vulnerable to functional decline, and to design targeted strategies for the prevention of functional impairment and related adverse health outcomes.

Association of polypharmacy with falls among older Chinese inpatients: A nationwide cohort study

AIM

Polypharmacy is prevalent among older adults and has been mainly reported to be associated with falls among community-dwelling or nursing home residents. Our study aimed to investigate the relationship between polypharmacy and falls among older Chinese hospitalized patients.

METHODS

A nationwide prospective cohort study included 9062 participants in six hospitals from China aged ≥65 years, with a 1-year follow-up period. Baseline polypharmacy and other health-related variables were collected when older inpatients were recruited on hospital admission. Polypharmacy was defined as patients who have taken five medications or more. Well-trained nurses assessed falls by telephone at follow up. We used multivariate logistic regression analysis to examine the association between polypharmacy and the risk of falls based on cross-sectional analyses and longitudinal analyses.

RESULTS

Of 9062 participants, the mean age was 72.42 years (SD= 5.69), and 5228 (57.69%) were men. After fully adjusted for age, sex, education, depression, cognitive impairment, low handgrip strength, frailty, various hospitals, and nutritional status, the cross-sectional and longitudinal analyses showed that inpatients with polypharmacy had an increased risk of falls (OR 1.37, 95%CI 1.17-1.56 for the cross-sectional association; OR 1.43, 95% CI 1.01-2.03 for the longitudinal association, respectively), compared with those without polypharmacy. In addition, subgroup analyses of the association between polypharmacy and 1-year falls, or history of falls was unchanged.

CONCLUSIONS

Polypharmacy was prevalent among older Chinese hospitalized patients and was an independent risk factor of 1-year falls, suggesting that clinicians should make a comprehensive assessment of medications, and deprescribing strategies should be implemented to reduce unnecessary medications for decreasing the rate of falls.

Anticholinergic burden measures and older people's falls risk: a systematic prognostic review

Introduction

Several adverse outcomes have been associated with anticholinergic burden (ACB), and these risks increase with age. Several approaches to measuring this burden are available but, to date, no comparison of their prognostic abilities has been conducted. This PROSPERO-registered systematic review (CRD42019115918) compared the evidence behind ACB measures in relation to their ability to predict risk of falling in older people.

Methods

Medline (OVID), EMBASE (OVID), CINAHL (EMBSCO) and PsycINFO (OVID) were searched using comprehensive search terms and a validated search filter for prognostic studies. Inclusion criteria included: participants aged 65 years and older, use of one or more ACB measure(s) as a prognostic factor, cohort or case-control in design, and reporting falls as an outcome. Risk of bias was assessed using the Quality in Prognosis Studies (QUIPS) tool.

Results

Eight studies reporting temporal associations between ACB and falls were included. All studies were rated high risk of bias in ⩾1 QUIPS tool categories, with five rated high risk ⩾3 categories. All studies (274,647 participants) showed some degree of association between anticholinergic score and increased risk of falls. Findings were most significant with moderate to high levels of ACB. Most studies (6/8) utilised the anticholinergic cognitive burden scale. No studies directly compared two or more ACB measures and there was variation in how falls were measured for analysis.

Conclusion

The evidence supports an association between moderate to high ACB and risk of falling in older people, but no conclusion can be made regarding which ACB scale offers best prognostic value in older people.

Plain language summary

A review of published studies to explore which anticholinergic burden scale is best at predicting the risk of falls in older people Introduction: One third of older people will experience a fall. Falls have many consequences including fractures, a loss of independence and being unable to enjoy life. Many things can increase the chances of having a fall. This includes some medications. One type of medication, known as anticholinergic medication, may increase the risk of falls. These medications are used to treat common health issues including depression and bladder problems. Anticholinergic burden is the term used to describe the total effects from taking these medications. Some people may use more than one of these medications. This would increase their anticholinergic burden. It is possible that reducing the use of these medications could reduce the risk of falls. We need to carry out studies to see if this is possible. To do this, we need to be able to measure anticholinergic burden. There are several scales available, but we do not know which is best.Methods: We wanted to answer: 'Which anticholinergic scale is best at predicting the risk of falling in older people?'. We reviewed studies that could answer this. We did this in a systematic way to capture all published studies. We restricted the search in several ways. We only included studies relevant to our question.Results: We found eight studies. We learned that people who are moderate to high users of these medications (often people who will use more than one of these medications) had a higher risk of falling. It was less clear if people who have a lower burden (often people who only use one of these medications) had an increased risk of falling. The low number of studies prevented us from determining if one scale was better than another.Conclusion: These findings suggest that we should reduce use of these medications. This could reduce the number falls and improve the well-being of older people.
