Transcranial direct current stimulation alleviates the pain severity in people suffering from knee osteoarthritis: a systematic review and meta-analysis

Considerable research has shown the benefits of transcranial direct current stimulation (tDCS) for the alleviation of pain associated with knee osteoarthritis (KOA). Still, a large variance in study protocols and observations across publications exists. We here thus completed a systematic review and meta-analysis to comprehensively and quantitatively characterize the effects of tDCS on KOA-related pain. A search strategy based on the Population, Intervention, Comparison, Outcome, and Study design (PICOS) principle was used to obtain the publications in 7 databases. Studies exploring the effects of tDCS on KOA-related pain were screened, and eligible studies were included. Ten studies of 518 participants using Visual Analogue Scale or Numeric Rating Scale to assess pain were included in the systematic review, and 9 of them were included in meta-analysis. The quality of these studies was good. Compared to control, tDCS induced significant short-term improvements in KOA-related pain with medium heterogeneity (standardized mean difference [SMD] = -0.91, 95% confidence interval [-1.24, -0.58], P < 0.001, I2 = 61%). Subgroup analyses showed that both home-based (SMD = -1.32, 95% CI [-1.65, -0.99], P < 0.001, I 2 = 0%) and laboratory-based intervention (SMD = -0.66, 95% CI [-0.99, -0.33], P < 0.001, I 2 = 40%) with at least 5 sessions per week (SMD = -1.02, 95% CI [-1.41, -0.64], P < 0.001, I 2 = 65%) and/or with a total number of at least 10 sessions (SMD = -1.12, 95% CI [-1.51, -0.74], P < 0.001, I 2 = 59%) can induce maximum benefits for the alleviation of KOA-related pain. The results here showed that tDCS is of great promise to alleviate KOA-related pain. Still, future studies with more rigorous design are needed to confirm the observations from this work, which can ultimately help the determination of appropriate intervention protocol that can maximize such benefits.

Identification of potentially causative drugs associated with hypotension: A scoping review

Drug-induced hypotension can be harmful and may lead to hospital admissions. The occurrence of hypotension during drug therapy is preventable through increased awareness. This scoping review aimed to provide a comprehensive overview of antihypertensive and nonantihypertensive drugs associated with hypotension in adults. A systematic literature search was conducted using MEDLINE, Embase and Cochrane Library, focusing on studies from January 2013 to May 2023. Search terms were developed to capture key concepts related to hypotension and adverse drug events in adults while excluding terms related to allergic reactions, phytotherapy and studies involving paediatric, pregnant or animal populations. The eligibility criteria included a wide range of study types evaluating hypotension as an adverse drug event across all healthcare settings. Relevant information was extracted from the included studies, while identified drugs associated with hypotension were categorised into drug classes. The review was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews checklist. In 97 eligible studies, we identified 26 antihypertensive drugs grouped into nine different antihypertensive classes and 158 other drugs grouped into 22 other drug classes. Common antihypertensive classes were angiotensin-converting enzyme inhibitors, beta blockers and diuretics. Frequently reported nonantihypertensive classes were neuroleptics, alpha-1 blockers for benign prostatic hyperplasia, benzodiazepines, opioids and antidepressants. The results highlight the importance of healthcare professionals being aware of nonantihypertensive drugs that can cause hypotension. This review provides a basis for future systematic reviews to explore dose-dependence, drug-drug interactions and confounding factors.

Multilevel factors influencing falls of older patients in hospital: The risk of hospital-induced delirium and the impact of nurse staffing

OBJECTIVE

This study aimed to explore the individual and organizational factors influencing falls among older inpatients, with a particular focus on the risk posed by hospital-induced delirium and the effect of nurse staffing levels.

METHODS

This retrospective cohort study utilized data from a national healthcare database to examine falls in hospitalized older adults, applying a mixed-effect logistic regression model RESULTS: Data from 391,902 patients across 580 hospitals revealed that 1.2 % of older inpatients experienced falls. Influential factors for falls included advanced age, the use of multiple medications and treatments, impaired mobility, and hospital-induced delirium. Nurse staffing levels markedly influenced the reduction of fall risks among older patients.

CONCLUSION

Falls among hospitalized older adults are a frequent consequence of multifaceted risk components, highlighting the need for comprehensive fall prevention strategies and adequate.

"It frees your body from that pain thought": A mixed-methods exploration of patterns, contexts, and experiences of cannabis use for pain in rural communities

U.S. adults increasingly report using cannabis to manage chronic pain and rural areas have inadequate comprehensive pain management. Using mixed methods, we aimed to understand how and why some rural adults use cannabis for pain, including within the context of co-use with opioids. Participants (N = 14, Oklahoma) were rural-dwelling adults who used tobacco and ≥1 other substance, including cannabis and opioids, ≥3 days per week. Participants completed 14 days of ecological momentary assessment (EMA) regarding substance use and subsequent in-depth interviews discussing maps of their substance use reports. Half (7/14) described cannabis use for chronic pain, and most of these (85%) reported use on ≥75% of EMA days. The most frequently reported cannabis use motive was therapeutic/medicinal (90% of use reports). Most reports were of combusted cannabis (88% of use reports) at home (99% of use reports). Same-day use of cannabis and opioids was relatively common (45% of daily surveys), but seemingly not within close temporal proximity. Interview narratives characterized cannabis as modifying pain-adjacent factors (eg, thoughts), not eliminating pain itself. They recounted using a repertoire of substances to manage different pain dimensions (eg, intensity, quality) and balance perceived trade-offs of different substances. Participants described high medical cannabis access, low pain specialist access, and most physicians as unwilling to discuss cannabis for pain. The findings suggest that rural-dwelling patients could benefit from increased access to comprehensive pain management, having cannabis addressed within pain management provider discussions, and that risks and benefits of cannabis use for pain must be better established. PERSPECTIVE: This study used a geographically explicit EMA mixed method to gather rich, intensive pilot data on cannabis use and co-use for chronic pain in rural Oklahoma. It provides unique insights to inform future research on cannabis use among a vulnerable and understudied subgroup of adults with pain-rural residents.

Prevalence of medication overload among older people with HIV: a MedSafer study

BACKGROUND

Older people with HIV (PWH) are at risk of polypharmacy (taking multiple medications). Most medications may be necessary and indicated to manage HIV (e.g., antiretroviral therapy [ART]) and HIV-associated comorbidities. However, some are potentially inappropriate medications (PIMs), defined as causing greater harm than benefit, which leads to medication overload. The objective of this study was to characterize polypharmacy (taking multiple medications) and medication overload (prescription of ≥ 1 PIMs) among older PWH.

METHODS

This retrospective study included older PWH (aged ≥ 50 years old) attending the tertiary care HIV clinic at the McGill University Health Centre (Montreal, Canada), from June 2022-June 2023. Patient characteristics, medications, and select laboratory values (e.g., CD4 count, hemoglobin A1C) were entered into the MedSafer software identifying PIMs and classifying them according to risk of adverse drug event. We measured the prevalence of polypharmacy (≥ 5 medications prescribed, both including and excluding ART) and medication overload (≥ 1 PIMs). Multivariable logistic regression identified factors associated with medication overload.

RESULTS

The study included 100 patients, with a median age of 59 years (IQR = 54-63; range 50-82); 42% female. Polypharmacy affected 89% of patients when including antiretroviral therapy (ART) and 60% when excluding ART. Medication overload was present in 58% of patients, and 37.4% of identified PIMs were classified as high-risk. Polypharmacy was the sole predictor of medication overload.

CONCLUSION

Older PWH are at significant risk of medication overload and receiving higher risk PIMs. Deprescribing PIMs in this population could improve medication appropriateness while reducing the risk of ADEs.

Exogenous Opioids and the Human Endocrine System: An Endocrine Society Scientific Statement

The use and misuse of opioids are a growing global problem. Although the effects of these drugs on the human endocrine system have been studied for decades, attention on their related clinical consequences, particularly on the hypothalamic-pituitary system and bone health, has intensified over recent years. This Statement appraises research data related to the impact of opioids on the gonadal and adrenal function. Whereas hypogonadism is well recognized as a side effect of opioids, the significance of their inhibitory actions on the hypothalamic-pituitary-adrenal system and the occurrence of clinically relevant adrenal insufficiency is not fully elucidated. The often-inconsistent results of studies investigating how opioids affect the secretion of GH, prolactin, arginine vasopressin, and oxytocin are assessed. The accumulating evidence of opioid actions on bone metabolism and their negative sequelae on bone mineral density and risk of fracture are also reviewed. In each section, available data on diagnostic and management approaches for opioid endocrine sequelae are described. This Statement highlights a plethora of gaps in research associated with the effects and clinical consequences of opioids on the endocrine system. It is anticipated that addressing these gaps will improve the care of people using or misusing opioids worldwide. The Statement is not intended to serve as a guideline or dictate treatment decisions.

Factors associated with fall risk increasing drug use in older black and white men and women: the Health ABC Study

BACKGROUND

Most older adults use medications that may increase falls, often defined as fall risk increasing drugs or "FRIDs". Two definitions for FRIDs, the Centers for Disease Control and Prevention's (CDC) Stopping Elderly Accidents, Deaths & Injuries (STEADI-Rx) and Swedish National Board of Health and Welfare (SNBHW) definitions, are widely accepted, though include different FRIDs in their definitions. Whether factors associated with FRID use in older adults differ by definition is unknown.

METHODS

We hypothesized that factors for FRID use will vary by FRID definition in 1,352 community-dwelling older Black and White adults with medication information in the Health, Aging and Body Composition Study (Health ABC; 2007-08 clinic visit; 83.4 ± 2.8 years; 54.1% women; 65.1% White). Multivariable logistic regression and multivariable negative binomial regression, progressively entering groups of covariates (demographics, lifestyle/behavior factors, and multimorbidity), modeled FRID use (yes/no) and count.

RESULTS

Of 87.0% participants using SNBHW FRIDs, 82.9% used cardiac medications, with lower use of all other FRIDs (range:1.1-12.4%). Of 86.6% participants using STEADI-Rx FRIDs, 80.5% used cardiac medications, with lower use of all other FRIDs (range:1.1-16.1%). Participants with FRID use by either definition were more likely to have chronic health conditions, a hospitalization in the prior year, higher non-FRIDs medication counts, higher Center for Epidemiologic Studies Depression Scale (CES-D) scores, and less physical activity (all p < 0.05). Participants with STEADI-Rx FRID use had poorer vision and higher Modified Mini-Mental State (3MS) scores. In multivariable logistic regression for SNBHW use, hypertension, body mass index (BMI), 3MS scores, and non-FRID count were positively associated with FRID use and poorer vision and Digit Symbol Substitution Test (DSST) scores were negatively associated. In addition to SNBHW factors, higher CES-D scores were associated with STEADI-Rx FRID use. In multivariable negative binomial regression, hypertension, higher BMI, CES-D scores, and non-FRID count were associated with higher FRID count and sleep problems with lower FRID count for both definitions. Higher 3MS and lower DSST scores were associated with higher STEADI-Rx FRID count. Women had lower SNBHW FRID count after adjustments.

CONCLUSIONS

Risk factors for FRID use in older adults differ slightly by STEADI-Rx and SNBHW FRIDs definition, but are largely similar.

Meteorological parameters and hospital-acquired falls-A multicenter retrospective study based on 10 years of adverse events reporting system data

Objective and rationale

Hospital-acquired falls are common and serious adverse events in medical institutions, with high incidence and injury rates. Studying the occurrence patterns of hospital-acquired falls is important for preventing falls in hospitalized patients. However, the effect of meteorological factors on hospital-acquired falls has not been elucidated. Therefore, this study explored the impact of meteorological parameters on hospital-acquired falls in Chongqing, China, and provided new ideas for the clinical prevention of falls in patients.

Methods

Correlation analysis and distributed lag nonlinear models were employed to analyze the relationship between 3890 cases of hospital-acquired falls and meteorological data in 13 hospitals in 11 districts and counties in Chongqing from January 2013 to April 2023.

Results

The number of hospital-acquired falls demonstrated a nonlinear correlation with the daily average relative humidity and negatively correlated with sunshine duration; however, temperature, air pressure, and wind speed were not correlated. Compared to the reference humidity (87 %), the immediate effects of daily average relative humidity (65-68 % and 90-97 %) increased the risk of hospital-acquired falls on the same day (relative risk [RR]:1.027-1.243). When the daily average relative humidity was 95-97 %, lags of 0-1 d and 8-12 d had greater effects on falls (RR:1.073-1.243). The daily average relative humidities of 62-74 % and 91-97 % were statistically significant at cumulative relative risk (CRR)of 4, 7, 10, and 14 d with a cumulative lag (CRR: 1.111-4.277). On sex and age stratification, the lag and cumulative effects of relative humidity more significantly impacted falls in women and patients aged ≥65 years.

Conclusion

Daily average relative humidity had a nonlinear correlation and lag effect on hospital-acquired falls; therefore, medical institutions should pay attention to the effect of relative humidity on hospital-acquired falls in patients, especially old and female patients.

Overdose Risk and Brain Injury (Traumatic Brain Injury/Acquired Brain Injury), A Commentary

OBJECTIVE

This commentary seeks to evaluate existing knowledge about the relationship between brain injury (BI) and overdose (OD), to unify distant bodies of literature, and to enhance prevention and treatment for opioid OD among individuals with BI.

BACKGROUND

There is a hidden epidemic of undiagnosed BI in the United States. Due to lack of screening, the vast majority of BI sufferers do not know they have a BI. Not only are those with BI at elevated risk for opioid use, misuse, and opioid use disorder, but also they are at elevated risk for OD. Conversely, those with OUD and those who experienced an OD, are more likely to sustain BI. Key Findings/Conclusions: The existing literature suggests that primary strategies to reduce ABI (Acquired Brain Injury)/TBI (Traumatic Brain Injury) harms involve addressing: screening, stigma, racial disparities, and popular misconceptions about OD. The association between TBI and OD is an underexamined public health issue, exacerbated by the bidirectional nature of the relationship. Not only is TBI a risk factor for opioid OD; opioid OD was also found to be a major cause of ABI, which can have lifelong effects similar to Alzheimer's disease. Screening tools for BI were underutilized and inconsistently implemented across reviewed studies. Enhanced screening population wide is a promising intervention, complemented with expanded treatment and research. Black individuals face worse outcomes in BI and treatment outcomes. Anti-racist strategies must fight inequity while addressing social and structural drivers of overdose and BI within the opioid and opioid overdose crises.

Beyond breathing: Systematic review of global chronic obstructive pulmonary disease guidelines for pain management

CONTEXT

Patients with chronic obstructive pulmonary disease (COPD) experience pain as both symptom and comorbidity. There has been no evaluation of the recommendations for pain management in updated clinical practice guidelines (CPGs).

OBJECTIVES

Update the evidence on pain management, determine alignment of pain management recommendations with best-practice, and advocate for optimal pain management in patients with COPD.

METHODS

PubMed, Guideline International Network, Guideline Portal, Agency for Healthcare Research and Quality, National Institute for Healthcare Excellence, Scottish International Guidelines Network, Institute of Medicine, grey literature, national websites, and bibliographies were searched. CPGs available online for stable COPD produced by organizations representing reputable knowledge of COPD management were included. CPGs unavailable online, not translatable into English, or not including techniques within the defined scope were excluded. Researchers performed frequency counts for the verbatim terms "pain," "physical activity," "exercise," "rehabilitation," "physical therap(ist)/(y), "physiotherap(ist)/(y)," recorded context, and collected recommendations for pain management/treatment when present.

RESULTS

Of 32 CPGs, 24 included "pain" verbatim. Of these, 13 included recommendations for pain treatment/management. Common recommendations included opioids, pharmacological management, further medical assessment, and surgical intervention. Two CPGs referred to palliative care, one CPG discussed treating cough, and one discussed massage, relaxation, and breathing.

CONCLUSIONS

Pain management recommendations vary and are not aligned with evidence. Pain should be addressed in patients with COPD, whether directly or indirectly related to the disease. Reduction of variability in pain management and the disease burden is necessary. Pain management should include referrals to providers who can maximize benefit of their services.

Experiences and Outcomes of Using e-Prescribing for Opioids: Rapid Scoping Review

BACKGROUND

e-Prescribing is designed to assist in facilitating safe and appropriate prescriptions for patients. Currently, it is unknown to what extent e-prescribing for opioids influences experiences and outcomes. To address this gap, a rapid scoping review was conducted.

OBJECTIVE

This rapid scoping review aims to (1) explore how e-prescribing has been used clinically; (2) examine the effects of e-prescribing on clinical outcomes, the patient or clinician experience, service delivery, and policy; and (3) identify current gaps in the present literature to inform future studies and recommendations.

METHODS

A rapid scoping review was conducted following the guidance of the JBI 2020 scoping review methodology and the World Health Organization guide to rapid reviews. A comprehensive literature search was completed by an expert librarian from inception until November 16, 2022. Three databases were electronically searched: MEDLINE (Ovid), Embase (Ovid), and Scopus (Elsevier). The search criteria were as follows: (1) e-prescribing programs targeted to the use or misuse of opioids, including those that were complemented or accompanied by clinically focused initiatives, and (2) a primary research study of experimental, quasi-experimental, observational, qualitative, or mixed methods design. An additional criterion of an ambulatory component of e-prescribing (eg, e-prescribing occurred upon discharge from acute care) was added at the full-text stage. No language limitations or filters were applied. All articles were double screened by trained reviewers. Gray literature was manually searched by a single reviewer. Data were synthesized using a descriptive approach.

RESULTS

Upon completing screening, 34 articles met the inclusion criteria: 32 (94%) peer-reviewed studies and 2 (6%) gray literature documents (1 thesis study and 1 report). All 33 studies had a quantitative component, with most highlighting e-prescribing from acute care settings to community settings (n=12, 36%). Only 1 (3%) of the 34 articles provided evidence on e-prescribing in a primary care setting. Minimal prescriber, pharmacist, and clinical population characteristics were reported. The main outcomes identified were related to opioid prescribing rates, alerts (eg, adverse drug events and drug-drug interactions), the quantity and duration of opioid prescriptions, the adoption of e-prescribing technology, attitudes toward e-prescribing, and potential challenges with the implementation of e-prescribing into clinical practice. e-Prescribing, including key features such as alerts and dose order sets, may reduce prescribing errors.

CONCLUSIONS

This rapid scoping review highlights initial promising results with e-prescribing and opioid therapy management. It is important that future work explores the experience of prescribers, pharmacists, and patients using e-prescribing for opioid therapy management with an emphasis on prescribers in the community and primary care. Developing a common set of quality indicators for e-prescribing of opioids will help build a stronger evidence base. Understanding implementation considerations will be of importance as the technology is integrated into clinical practice and health systems.

Neurocognitive Effect of Biased µ-Opioid Receptor Agonist Oliceridine, a Utility Function Analysis and Comparison with Morphine

BACKGROUND

Oliceridine (Olinvyk) is a μ-opioid receptor agonist that in contrast to conventional opioids preferentially engages the G-protein-coupled signaling pathway. This study was designed to determine the utility function of oliceridine versus morphine based on neurocognitive tests and cold pressor test.

METHODS

The study had a randomized, double-blind, placebo-controlled, partial block three-way crossover design. Experiments were performed in 20 male and female volunteers. The subjects received intravenous oliceridine (1 or 3 mg; cohorts of 10 subjects/dose), morphine (5 or 10 mg; cohorts of 10 subjects/dose), or placebo on three separate occasions. Before and after dosing, neurocognitive tests, cold pressor test, and plasma drug concentrations were obtained at regular intervals. Population pharmacokinetic-pharmacodynamic analyses served as the basis for construction of a utility function, which is an objective function of probability of benefit minus probability of harm. Antinociception served as the measure of benefit, and slowing of saccadic peak velocity and increased body sway as the measures of neurocognitive harm.

RESULTS

The oliceridine and morphine C50 values, i.e., the effect-site concentrations causing 50% effect, were as follows: antinociception, 13 ± 2 and 23 ± 7 ng/ml; saccadic peak velocity, 90 ± 14 and 54 ± 15 ng/ml; and body sway, 10 ± 2 and 5.6 ± 0.8 ng/ml, respectively. The ratio oliceridine/morphine of the therapeutic indices, C50(benefit)/C50(harm), were 0.34 (95% CI, 0.17 to 0.7; P < 0.01) for saccadic peak velocity and 0.33 (0.16 to 0.50; P < 0.01) for body sway. The oliceridine utility was positive across the effect-site concentration 5 to 77 ng/ml, indicative of a greater probability of benefit than harm. The morphine utility was not significantly different from 0 from 0 to 100 ng/ml. Over the concentration range 15 to 50 ng/ml, the oliceridine utility was superior to that of morphine (P < 0.01). Similar observations were made for body sway.

CONCLUSIONS

These data indicate that over the clinical concentration range, oliceridine is an analgesic with a favorable safety profile over morphine when considering analgesia and neurocognitive function.

EDITOR’S PERSPECTIVE

Emergency Department Pain Management in the Older Adult

Pain assessment and management in older adults is complex and requires evaluation and consideration of the type of pain, the acuity of the condition, comorbidities, and medications. Many older adults do not receive appropriate therapy for painful conditions in the emergency department (ED). This brief review article is focused on pharmacologic agents, drug-drug interactions, drug-disease interactions, and approaches in the management of painful conditions seen in older adults in the emergency department. Recommendations for specific painful conditions such as fragility fractures are discussed.

Perioperative Pain Management for Distal Radius Fractures

Distal radius fractures have a high incidence among both young and elderly patients, and in many instances require operative intervention. When operative intervention is employed, adequate pain management is essential to decrease postoperative complications, such as chronic pain and disability, while minimizing the risk of prolonged opioid use and dependence. Strategies to optimize pain management include regional anesthesia, preoperative dosing of medication, multimodal regimens, long-acting selective opioids at the time of surgery, corticosteroids, and non-pharmacologic therapies.

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.

European position paper on polypharmacy and fall-risk-increasing drugs recommendations in the World Guidelines for Falls Prevention and Management: implications and implementation

Falls prevention and management in older adults is a critical global challenge. One of the key risk factors for falls is the use of certain medications. Therefore, to prevent medication-related falls, the following is recommended in the recent World Guidelines for Falls Prevention and Management: (1) assess for fall history and the risk of falls before prescribing potential fall-risk-increasing drugs (FRIDs), (2) use a validated, structured screening and assessment tool to identify FRIDs when performing a medication review, (3) include medication review and appropriate deprescribing of FRIDs as a part of the multifactorial falls prevention intervention, and (4) in long-term care residents, if multifactorial intervention cannot be conducted due to limited resources, the falls prevention strategy should still always include deprescribing of FRIDs.In the present statement paper, the working group on medication-related falls of the World Guidelines for Falls Prevention and Management, in collaboration with the European Geriatric Medicine Society (EuGMS) Task and Finish group on FRIDs, outlines its position on how to implement and execute these recommendations in clinical practice.Preferably, the medication review should be conducted as part of a comprehensive geriatric assessment to produce a personalized and patient-centered assessment. Furthermore, the major pitfall of the published intervention studies so far is the suboptimal implementation of medication review and deprescribing. For the future, it is important to focus on gaining which elements determine successful implementation and apply the concepts of implementation science to decrease the gap between research and practice.

TANGO: Development of Consumer Information Leaflets to Support TAperiNG of Opioids in Older Adults with Low Back Pain and Hip and Knee Osteoarthritis

INTRODUCTION

Globally, the rate of opioid prescription is high for chronic musculoskeletal conditions despite guidelines recommending against their use as their adverse effects outweigh their modest benefit. Deprescribing opioids is a complex process that can be hindered by multiple prescriber- and patient-related barriers. These include fear of the process of, or outcomes from, weaning medications, or a lack of ongoing support. Thus, involving patients, their carers, and healthcare professionals (HCPs) in the development of consumer materials that can educate and provide support for patients and HCPs over the deprescribing process is critical to ensure that the resources have high readability, usability, and acceptability to the population of interest.

OBJECTIVE

This study aimed to (1) develop two educational consumer leaflets to support opioid tapering in older people with low back pain (LBP) and hip or knee osteoarthritis (HoKOA), and (2) evaluate the perceived usability, acceptability, and credibility of the consumer leaflets from the perspective of consumers and HCPs.

DESIGN

This was an observational survey involving a consumer review panel and an HCP review panel.

PARTICIPANTS

30 consumers (and/or their carers) and 20 HCPs were included in the study. Consumers were people older than 65 years of age who were currently experiencing LBP or HoKOA, and with no HCP background. Carers were people who provided unpaid care, support, or assistance to an individual meeting the inclusion criteria for consumers. HCPs included physiotherapists (n = 9), pharmacists (n = 7), an orthopaedic surgeon (n = 1), a rheumatologist (n = 1), nurse practitioner (n = 1) and a general practitioner (n = 1), all with at least three years of clinical experience and who reported working closely with this target patient population within the last 12 months.

METHODS

Prototypes of two educational consumer leaflets (a brochure and a personal plan) were developed by a team of LBP, OA, and geriatric pharmacotherapy researchers and clinicians. The leaflet prototypes were evaluated by two separate chronological review panels involving (1) consumers and/or their carers, and (2) HCPs. Data collection for both panels occurred via an online survey. Outcomes were the perceived usability, acceptability, and credibility of the consumer leaflets. Feedback received from the consumer panel was used to refine the leaflets, before circulating the leaflets for further review by the HCP panel. Additional feedback from the HCP review panel was then used to refine the final versions of the consumer leaflets.

RESULTS

Both consumers and HCPs perceived the leaflets and personal plan to be usable, acceptable, and credible. Consumers rated the brochure against several categories, which scored between 53 and 97% positive responses. Similarly, the overall feedback provided by HCPs was 85-100% positive. The modified System Usability Scale scores obtained from HCPs was 55-95% positive, indicating excellent usability. Feedback for the personal plan from both HCPs and consumers was largely positive, with consumers providing the highest positive ratings (80-93%). While feedback for HCPs was also high, we did identify that prescribers were hesitant to provide the plan to patients frequently (no positive responses).

CONCLUSIONS

This study led to the development of a leaflet and personal plan to support the reduction of opioid use in older people with LBP or HoKOA. The development of the consumer leaflets incorporated feedback provided by HCPs and consumers to maximise clinical effectiveness and future intervention implementation.

The cost of opioid use disorder-related conditions in Medicare

BACKGROUND

Medicare coverage excludes some levels of substance use disorder (SUD) care, such as intensive outpatient and residential treatment. Expanding access to SUD treatment could increase Medicare spending. However, these costs could be offset if SUD treatment resulted in cost savings from reducing SUD-related medical events and SUD-related medical comorbidities.

METHODS

This study estimated cost savings from expanding access to SUD treatment for persons with opioid use disorders (OUD) using three methods. First, we compared total Medicare fee-for-service spending on individuals with OUD and no treatment with OUD medications (MOUD) to Medicare spending on individuals without OUD after matching on age/sex/Medicare-Medicaid eligibility status. Second, we compared Medicare spending on individuals with OUD who received MOUD to spending individuals with OUD who did not receive MOUD. Third, we determined OUD-attributable Medicare spending for comorbid physical and mental conditions with a strong association with OUD.

RESULTS

Beneficiaries with OUD but no MOUD totaled $15.8 billion more than beneficiaries without OUD. Beneficiaries with OUD but no MOUD totaled $12.1 billion more than individuals with OUD and MOUD. Lastly, Medicare spending on OUD-attributable comorbidities was $4.7 billion if all medical and mental health comorbidities were included and $3.0 billion with only medical comorbidities. The totals could be 1.7 times higher if Medicare Advantage enrollees were included.

CONCLUSION

Expanding Medicare coverage of appropriate levels of care could improve access to effective treatment and reduce the costs associated with untreated OUD. This will likely result in substantial Medicare cost savings.

Paracetamol versus paracetamol/tramadol in postoperative intertrochanteric fracture: A noninferiority, randomized, controlled, double-blind study

BACKGROUND

One of the most common osteoporotic fractures among the elderly is hip fracture with tramadol frequently being prescribed for these patients. To decrease the risk of falling from tramadol, this study aimed to ascertain the effectiveness of paracetamol compared to paracetamol/tramadol for pain control following hip fixation surgery.

METHOD

This was a noninferiority, double-blind, randomized, controlled trial at a tertiary care hospital. All patients were recruited between February 2020 and March 2022. Patients were randomly assigned to paracetamol alone (Group A) or paracetamol/tramadol (Group B). All patients in both groups followed the same protocol for the first two days after surgery. To ascertain differences in pain control between the two groups, different regimens were followed from postoperative days 3-5. Pain scores were assessed by a visual analog scale (VAS). All patients were asked to complete a satisfaction questionnaire on day 5.

RESULT

A total of 30 patients were randomly allocated into Group A (paracetamol alone) and 30 into Group B (paracetamol + tramadol). The mean pain score for Group A was 5.85 ± 0.52 and 5.35 ± 0.74 for Group B. Mean cumulative doses in Group A were 4.50 ± 1.33 and 4.06 ± 1.18 in Group B. Although the mean satisfaction with pain management was higher in Group B, this was not statistically significant.

CONCLUSION

VAS scores from Group A were slightly higher than Group B. Based on a 2.0-point noninferiority margin of pain, paracetamol alone was not inferior to paracetamol/tramadol in postoperative intertrochanteric fracture.

Cohort Description: Preventing an Opioid Epidemic in Norway - Focusing on Treatment of Chronic Pain (POINT) - A National Registry-Based Study

AIM

The POINT project aims to provide evidence to optimise chronic pain management, prevent adverse consequences of opioids, and improve chronic pain patients' pain relief, functional capacity, and quality of life. We describe the outline of the project and its work packages. More specifically, we describe a cohort of persons with chronic pain and a cohort of long-term opioid users identified from a national registry linkage.

DATA SOURCES

The project utilises data from nationwide healthcare and population registers in Norway. Using the Norwegian Prescription Database, we identified a cohort of persons who have been dispensed drugs reimbursed for chronic pain and a cohort of persons who used opioids long term from 2010 to 2019. Data from the Norwegian Registry for Primary Health Care and the Norwegian Patient Registry (2008-2019), Cancer Registry (1990-2018) Cause of Death Registry (2010-2019) and demographic and socioeconomic registers from Statistics Norway (2010-2019) were linked to the cohorts.

STUDY POPULATION

There were 568,869 participants with chronic pain. Sixty-three percent of the cohort was women, and the mean age was 57.1 years. There were 336,712 long-term opioid users (58.6% women; 60.9 years). In chronic pain and long-term opioid user cohorts, the most frequent musculoskeletal diagnosis was back pain diagnosed in primary care (27.6% and 30.7%). Psychiatric diagnoses were also common.

MAIN VARIABLES

Upcoming studies will utilise psychiatric and somatic diagnoses from the patient registers, drug use from the prescription register, causes of death, demographics, and socioeconomic status (eg, education, income, workability, immigrant status) as exposures or outcomes.

CONCLUSION AND FUTURE PLANS

The two cohorts have numerous pain-related diagnoses, especially in the musculoskeletal system, and noticeably frequent somatic and psychiatric morbidity. The POINT project also includes later work packages that explore prescriber and patient perspectives around safe and effective treatment of chronic pain.

Prevalence and predictors of medication-related emergency department visit in older adults: A multicenter study linking national claim database and hospital medical records

Objectives: Older adults are more likely to experience drug-related problems (DRP), which could lead to medication-related emergency department visits (MRED). To properly evaluate MRED, the entire history of drug use should be evaluated in a structured manner. However, limited studies have identified MRED with complete prescription records. We aimed to evaluate the prevalence and risk factors of MRED among community-dwelling older patients by linking national claims data and electronic medical records using a standardized medication related admission identification method. Methods: We included older patients who visited the emergency departments of four participating hospitals in 2019. Among the 54,034 emergency department (ED) visitors, we randomly selected 6,000 patients and structurally reviewed their medical records using a standardized MRED identification method after linking national claims data and electronic medical records. We defined and categorized MRED as ED visits associated with adverse drug events and those caused by the underuse of medication, including treatment omission and noncompliance and assessed as having probable or higher causality. We assessed preventability using Schumock and Thornton criteria. Results: MRED was observed in 14.3% of ED visits, of which 76% were preventable. In addition, 32.5% of MRED cases were related to underuse or noncompliance, and the rest were related to adverse drug events. Use of antipsychotics, benzodiazepines, anticoagulants, traditional nonsteroidal anti-inflammatory drugs without the use of proton pump inhibitors, P2Y12 inhibitors, insulin, diuretics, and multiple strong anticholinergic drugs were identified as predictors of MRED. Conclusion: One in seven cases of ED visits by older adults were medication related and over three-quarters of them were preventable. These findings suggest that DRPs need to be systemically screened and intervened in older adults who visit ED.

World guidelines for falls prevention and management for older adults: a global initiative

BACKGROUND

falls and fall-related injuries are common in older adults, have negative effects on functional independence and quality of life and are associated with increased morbidity, mortality and health related costs. Current guidelines are inconsistent, with no up-to-date, globally applicable ones present.

OBJECTIVES

to create a set of evidence- and expert consensus-based falls prevention and management recommendations applicable to older adults for use by healthcare and other professionals that consider: (i) a person-centred approach that includes the perspectives of older adults with lived experience, caregivers and other stakeholders; (ii) gaps in previous guidelines; (iii) recent developments in e-health and (iv) implementation across locations with limited access to resources such as low- and middle-income countries.

METHODS

a steering committee and a worldwide multidisciplinary group of experts and stakeholders, including older adults, were assembled. Geriatrics and gerontological societies were represented. Using a modified Delphi process, recommendations from 11 topic-specific working groups (WGs), 10 ad-hoc WGs and a WG dealing with the perspectives of older adults were reviewed and refined. The final recommendations were determined by voting.

RECOMMENDATIONS

all older adults should be advised on falls prevention and physical activity. Opportunistic case finding for falls risk is recommended for community-dwelling older adults. Those considered at high risk should be offered a comprehensive multifactorial falls risk assessment with a view to co-design and implement personalised multidomain interventions. Other recommendations cover details of assessment and intervention components and combinations, and recommendations for specific settings and populations.

CONCLUSIONS

the core set of recommendations provided will require flexible implementation strategies that consider both local context and resources.
