Safer medicines To reduce falls and refractures for OsteoPorosis (#STOP): a study protocol for a randomised controlled trial of medical specialist-initiated pharmacist-led medication management reviews in primary care.

INTRODUCTION: Minimal trauma fractures (MTFs) often occur in older patients with osteoporosis and may be precipitated by falls risk-increasing drugs. One category of falls risk-increasing drugs of concern are those with sedative/anticholinergic properties. Collaborative medication management services such as Australia's Home Medicine Review (HMR) can reduce patients' intake of sedative/anticholinergics and improve continuity of care. This paper describes a protocol for an randomised controlled trial to determine the efficacy of an HMR service for patients who have sustained MTF. METHOD AND ANALYSIS: Eligible participants are as follows: ≥65 years of age, using ≥5 medicines including at least one falls risk-increasing drug, who have sustained an MTF and under treatment in one of eight Osteoporosis Refracture Prevention clinics in Australia. Consenting participants will be randomised to control (standard care) or intervention groups. For the intervention group, medical specialists will refer to a pharmacist for HMR focused on reducing falls risk predominately through making recommendations to reduce falls risk medicines, and adherence to antiosteoporosis medicines. Twelve months from treatment allocation, comparisons between groups will be made. The main outcome measure is participants' cumulative exposure to sedative and anticholinergics, using the Drug Burden Index. Secondary outcomes include medication adherence, emergency department visits, hospitalisations, falls and mortality. Economic evaluation will compare the intervention strategy with standard care. ETHICS AND DISSEMINATION: Approval was obtained via the New South Wales Research Ethics and Governance Information System (approval number: 2021/ETH12003) with site-specific approvals granted through Human Research Ethics Committees for each research site. Study outcomes will be published in peer-reviewed journals. It will provide robust insight into effectiveness of a pharmacist-based intervention on medicine-related falls risk for patients with osteoporosis. We anticipate that this study will take 2 years to fully accrue including follow-up. TRIAL REGISTRATION NUMBER: ACTRN12622000261718.

Epidemiology, clinical features and management of patients presenting to European emergency departments with acute cocaine toxicity: comparison between powder cocaine and crack cocaine cases.

Objective: To analyse the epidemiology, clinical picture and emergency department (ED) management of a large series of patients who presented to European EDs after cocaine consumption, comparing data from powder (C1 group) and crack (C2 group) consumers. Methods: Between October 2013 and December 2016, the Euro-DEN Plus Registry recorded 17,371 consecutive acute recreational drug toxicity presentations to 22 EDs in 14 European countries. Epidemiological and demographic data, co-ingestion of alcohol and other drugs, clinical features, ED management and outcome (death) were analysed for cocaine cases, and comparison of clinical picture in C1 and C2 patients were performed adjusting for alcohol and other drug co-ingestion. Results: We included 3002 cases (C1: 2600; C2: 376; mixed consumption: 26): mean age 32(9) years, 23% female. The proportion of presentations involving cocaine varied significantly between countries (>30% in Malta, Spain, France, Denmark) and only centres in France, United Kingdom, Poland, Ireland and Malta recorded crack-related cases. Cocaine was frequently used with ethanol (74.3%, C1>C2) and other drugs (56.8%, C2>C1), the most frequent amphetamine (19.4%, C1>C2) and opioids (18.9%, C2>C1). C2 patients were more likely to have clinically significant episodes of hypotension (adjusted OR = 2.35; 95%CI = 1.42-3.89), and bradypnea (1.81; 1.03-3.16) and systolic blood pressure >180 mmHg on ED arrival (2.59; 1.28-5.25); while less likely anxiety (0.51; 0.38-0.70), chest pain (0.47; 0.31-0.70), palpitations (0.57; 0.38-0.84), vomiting (0.54; 0.32-0.90), and tachycardia on ED arrival (0.52; 0.39-0.67). Sedative drugs were given in 29.3%. The median length of hospital stay was 4:02 h, 22.1% patients were hospitalized, and 0.4% (n = 12) died. Conclusion: Cocaine is commonly involved in European ED presentations with acute recreational drug toxicity, but there is variation across Europe not just in the involvement of cocaine but in the proportion related to powder versus crack. Some differences in clinical picture and ED management exist between powder cocaine and crack consumers.

Value-based insurance designs in the treatment of mental health disorders.

OBJECTIVES: To explore the feasibility of applying value-based insurance designs (V-BIDs) to the treatment of mental health disorders and address any additional challenges posed. STUDY DESIGN: Literature review. METHODS: This study consisted of 3 steps. First, we reviewed the historical literature on V-BIDs and challenges revealed by various programs. Second, we reviewed the literature on the cost, scope, and various treatment options for mental health disorders. Third, we analyzed potential challenges in applying V-BIDs to mental health disorders. RESULTS: Many challenges exist in applying V-BID to the management and treatment of physical and mental health disorders, such as getting buy-in from insurance companies and from large employers, and adherence issues for those with diminished capabilities to comprehend program benefits and those lacking family support. Additional challenges specific to mental health disorders include: a) privacy (ie, sensitivity issues) in implementing the program in certain settings; and b) sociodemographic variables, along with perceptions of mental disorder severity and need that currently affect the take-up of mental health services. CONCLUSIONS: Research projects focused on applying V-BID to mental health disorders that address these challenges and demonstrate cost savings will be needed (ie, comparative effectiveness research studies), along with additional information on changes in disability-adjusted life-years, and on-demand responses across different mental health services, populations, and care settings.

Bridging the osteoporosis treatment gap: performance and cost-effectiveness of a fracture liaison service.

Individuals who sustain fragility fractures are at high risk of refracture. However, osteoporosis treatment rates remain low for these patients. Therefore, we aimed to assess the performance and cost-effectiveness of introducing a fracture liaison service (FLS) into a tertiary hospital. In "nonhospitalized" ambulatory patients who had sustained fragility fractures, we assessed baseline osteoporosis investigation and treatment rates, and subsequently, the impact of introducing an orthopedic osteoporosis policy and an FLS. Outcomes measured were uptake of osteoporosis intervention, patient satisfaction, and quality-adjusted life years (QALYs) gained. QALYs were calculated over 5 years using predicted fracture risks without intervention and estimated fracture risk reduction with intervention. At baseline (n = 49), 2% of ambulatory patients who had sustained fragility fractures underwent dual-energy X-ray absorptiometry (DXA) and 6% received osteoporosis-specific medication. After introduction of an osteoporosis policy (n = 58), 28% were investigated with DXA (p < 0.0001). However, treatment rates were unchanged. An FLS was introduced, reviewing 203 new patients over the inaugural 2 years (mean age [standard deviation], 67 (11) years; 77% female). All underwent DXA, and criteria for osteoporosis and osteopenia were identified in 44% and 40%, respectively. Osteoporosis medications were prescribed to 61% patients (risedronate: 22%, alendronate: 16%, strontium ranelate: 13%, zoledronic acid: 8%, other: 2%). Eighty-five of 90 questionnaire respondents were very satisfied or satisfied with the FLS. With the treatment prescribed over 5 years, we conservatively estimated that this FLS would reduce nonvertebral refractures from 59 to 50, improving QALYs by 0.054 and costing $1716 per patient (incremental cost-effectiveness ratio: $31749). This FLS model improves uptake of osteoporosis intervention guidelines, is popular among patients, and improves cost-effectiveness. Thus, it has the capacity to substantially improve health in a cost-effective way.
