Perspectives on Fracture Liaison Service in Austria: clinical and economic considerations.

Osteoporosis is a widespread disease and affects over 500,000 people in Austria. Fragility fractures are associated with it and represent not only an individual problem for the patients, but also an enormous burden for the healthcare system. While trauma surgery care is well provided in Vienna, there is an enormous treatment gap in secondary prevention after osteoporotic fracture. Systematic approaches such as the Fracture Liaison Service (FLS) aim to identify patients with osteoporosis after fracture, to clarify diagnostically, to initiate specific therapy, and to check therapy adherence. The aim of this article is to describe the practical implementation and operational flow of an already established FLS in Vienna. This includes the identification of potential FLS inpatients, the diagnostic workup, and recommendations for an IT solution for baseline assessment and follow-up of FLS patients. We summarize the concept, benefits, and limitations of FLS and provide prospective as well as clinical and economic considerations for a city-wide FLS, managed from a central location. Future concepts of FLS should include artificial intelligence for vertebral fracture detection and simple IT tools for the implementation of FLS in the outpatient sector.

The Use of Precision Epigenetic Methods for the Diagnosis and Care of Stable Coronary Heart Disease Reduces Healthcare Costs.

INTRODUCTION: The cost of secondary prevention of coronary heart disease (CHD) is continuing to increase, with a substantial portion of this acceleration being driven by the expense of confirmatory diagnostic testing. Conceivably, newly developed precision epigenetic technologies could drive down these costs. However, at the current time, their impact on overall expense for CHD care is poorly understood. We hypothesized that the use of a newly developed, highly sensitive, and specific epigenetic test, PrecisionCHD, could decrease the costs of secondary prevention. METHODS: To test this hypothesis, we constructed a budget impact analysis using a cost calculation model that examined the effects of substituting PrecisionCHD for conventional CHD diagnostic tests on the expenses of the initial evaluation and first year of care of stable CHD using a 1-year time horizon with no discounting. RESULTS: The model projected that for a commercial insurer with one million members, full adoption of PrecisionCHD as the primary method of initial CHD assessment would save approximately $113.6 million dollars in the initial year. CONCLUSION: These analyses support the use of precision epigenetic methods as part of the initial diagnosis and care of stable CHD and can meaningfully reduce cost. Real-world pilots to test the reliability of these analyses are indicated.

Cost-effectiveness of temperature monitoring to help prevent foot ulcer recurrence in people with diabetes: A multicenter randomized controlled trial.

AIMS: Diabetes-related foot ulcers are common, costly, and frequently recur. Multiple interventions help prevent these ulcers. However, none of these have been prospectively investigated for cost-effectiveness. Our aim was to evaluate the cost-effectiveness of at-home skin temperature monitoring to help prevent diabetes-related foot ulcer recurrence. MATERIALS AND METHODS: Multicenter randomized controlled trial. We randomized 304 persons at high diabetes-related foot ulcer risk to either usual foot care plus daily at-home foot skin temperature monitoring (intervention) or usual care alone (control). Primary outcome was cost-effectiveness based on foot care costs and quality-adjusted life years (QALY) during 18 months follow-up. Foot care costs included costs for ulcer prevention (e.g., footwear, podiatry) and for ulcer treatment when required (e.g., consultation, hospitalisation, amputation). Incremental cost-effectiveness ratios were calculated for intervention versus usual care using probabilistic sensitivity analysis for willingness-to-pay/accept levels up to €100,000. RESULTS: The intervention had a 45% probability of being cost-effective at a willingness-to-accept of €50,000 per QALY lost. This resulted from (non-significantly) lower foot care costs in the intervention group (€6067 vs. €7376; p = 0.45) because of (significantly) fewer participants with ulcer recurrence(s) in 18 months (36% vs. 47%; p = 0.045); however, QALYs were (non-significantly) lower in the intervention group (1.09 vs. 1.12; p = 0.35), especially in those without foot ulcer recurrence (1.09 vs. 1.17; p = 0.10). CONCLUSIONS: At-home skin temperature monitoring for diabetes-related foot ulcer prevention compared with usual care is at best equally cost-effective. The intervention resulted in cost-savings due to preventing foot ulcer recurrence and related costs, but this came at the expense of QALY loss, potentially from self-monitoring burdens.

Return on investment of fracture liaison services: a systematic review and analysis.

Fracture liaison services (FLS) have been proven clinically effective and cost-effective in preventing subsequent fractures among patients with an existing fragility fracture. Little is known about their monetary benefits such as their return on investment (ROI). This systematic review aimed to investigate the ROI of FLS and identify the FLS characteristics with better ROI. Studies on the cost-effectiveness of FLS published between January 2000 and December 2022 were searched from MEDLINE, EMBASE, PubMed, and Cochrane Central. Two independent reviewers conducted study selection and data extraction. ROI was calculated based on the difference between monetary benefits and FLS costs divided by the FLS costs. Subgroup analysis of ROI was performed across FLS types and FLS design details. A total of 23 FLS were included in this review. The majority of them were targeting patients aged over 50 years having fractures without identified sites. The mean ROI of these FLS was 10.49 (with a median ROI of 7.57), and 86.96% of FLS had positive ROI. FLS making treatment recommendations yielded the highest ROI (with a mean ROI of 18.39 and a median of 13.60). Incorporating primary care providers (with a mean ROI of 16.04 and a median of 13.20) or having them as program leaders (with a mean ROI of 12.07 and a median of 12.07) has demonstrated a high ROI. FLS for specific fracture sites had great monetary return. Intensive FLS such as type A and B FLS programs had higher ROI than non-intensive type C and D FLS. This review revealed a 10.49-fold monetary return of FLS. Identified characteristics contributing to greater economic return informed value-for-money FLS designs. Findings highlight the importance of FLS and the feasibility of expanding their contribution in mitigating the economic burden of osteoporotic fracture and are conducive to the promotion of FLS internationally.

Aspirin for Secondary Prevention of Cardiovascular Disease in 51 Low-, Middle-, and High-Income Countries.

Importance: Aspirin is an effective and low-cost option for reducing atherosclerotic cardiovascular disease (CVD) events and improving mortality rates among individuals with established CVD. To guide efforts to mitigate the global CVD burden, there is a need to understand current levels of aspirin use for secondary prevention of CVD. Objective: To report and evaluate aspirin use for secondary prevention of CVD across low-, middle-, and high-income countries. Design, Setting, and Participants: Cross-sectional analysis using pooled, individual participant data from nationally representative health surveys conducted between 2013 and 2020 in 51 low-, middle-, and high-income countries. Included surveys contained data on self-reported history of CVD and aspirin use. The sample of participants included nonpregnant adults aged 40 to 69 years. Exposures: Countries' per capita income levels and world region; individuals' socioeconomic demographics. Main Outcomes and Measures: Self-reported use of aspirin for secondary prevention of CVD. Results: The overall pooled sample included 124 505 individuals. The median age was 52 (IQR, 45-59) years, and 50.5% (95% CI, 49.9%-51.1%) were women. A total of 10 589 individuals had a self-reported history of CVD (8.1% [95% CI, 7.6%-8.6%]). Among individuals with a history of CVD, aspirin use for secondary prevention in the overall pooled sample was 40.3% (95% CI, 37.6%-43.0%). By income group, estimates were 16.6% (95% CI, 12.4%-21.9%) in low-income countries, 24.5% (95% CI, 20.8%-28.6%) in lower-middle-income countries, 51.1% (95% CI, 48.2%-54.0%) in upper-middle-income countries, and 65.0% (95% CI, 59.1%-70.4%) in high-income countries. Conclusion and Relevance: Worldwide, aspirin is underused in secondary prevention, particularly in low-income countries. National health policies and health systems must develop, implement, and evaluate strategies to promote aspirin therapy.

Cost-effectiveness of Cardiac Telerehabilitation With Relapse Prevention for the Treatment of Patients With Coronary Artery Disease in the Netherlands.

Importance: Cardiac telerehabilitation (CTR) has been found to be a safe and beneficial alternative to traditional center-based cardiac rehabilitation (CR) and might be associated with higher participation rates by reducing barriers to CR use. However, implementation of CTR interventions remains low, which may be owing to a lack of cost-effectiveness analyses of data from large-scale randomized clinical trials. Objective: To assess the cost-effectiveness of CTR with relapse prevention compared with center-based CR among patients with coronary artery disease. Design, Setting, and Participants: This economic evaluation performed a cost-utility analysis of data from the SmartCare-CAD (Effects of Cardiac Telerehabilitation in Patients With Coronary Artery Disease Using a Personalized Patient-Centred ICT Platform) randomized clinical trial. The cost-effectiveness and utility of 3 months of cardiac telerehabilitation followed by 9 months of relapse prevention were compared with the cost-effectiveness of traditional center-based cardiac rehabilitation. The analysis included 300 patients with stable coronary artery disease who received care at a CR center serving 2 general hospitals in the Netherlands between May 23, 2016, and July 26, 2018. All patients were entering phase 2 of outpatient CR and were followed up for 1 year (until August 14, 2019). Data were analyzed from September 21, 2020, to September 24, 2021. Intervention: After baseline measurements were obtained, participants were randomly assigned on a 1:1 ratio to receive CTR (intervention group) or center-based CR (control group) using computerized block randomization. After 6 supervised center-based training sessions, patients in the intervention group continued training at home using a heart rate monitor and accelerometer. Patients uploaded heart rate and physical activity data and discussed their progress during a weekly video consultation with their physical therapist. After 3 months, weekly coaching was concluded, and on-demand coaching was initiated for relapse prevention; patients were instructed to continue using their wearable sensors and were contacted in cases of nonadherence to the intervention or reduced exercise or physical activity volumes. Main Outcomes and Measures: Quality-adjusted life-years were assessed using the EuroQol 5-Dimension 5-Level survey (EQ-5D-5L) and the EuroQol Visual Analogue Scale (EQ-VAS), and cardiac-associated health care costs and non-health care costs were measured by health care consumption, productivity, and informal care questionnaires (the Medical Consumption Questionnaire, the Productivity Cost Questionnaire, and the Valuation of Informal Care Questionnaire) designed by the Institute for Medical Technology Assessment. Costs were converted to 2020 price levels (in euros) using the Dutch consumer price index (to convert to US dollars, euro values were multiplied by 1.142, which was the mean exchange rate in 2020). Results: Among 300 patients (266 men [88.7%]), the mean (SD) age was 60.7 (9.5) years. The quality of life among patients receiving CTR vs center-based CR was comparable during the study according to the results of both utility measures (mean difference on EQ-5D-5L: -0.004; P = .82; mean difference on EQ-VAS: -0.001; P = .92). Intervention costs were significantly higher for CTR (mean [SE], €224 [€4] [$256 ($4)]) compared with center-based CR (mean [SE], €156 [€5] [$178 ($6)]; P < .001); however, no difference in overall cardiac health care costs was observed between CTR (mean [SE], €4787 [€503] [$5467 ($574)] and center-based CR (mean [SE], €5507 [€659] [$6289 ($753)]; P = .36). From a societal perspective, CTR was associated with lower costs compared with center-based CR (mean [SE], €20 495 [€ 2751] [$23 405 ($3142)] vs €24 381 [€3613] [$27 843 ($4126)], respectively), although this difference was not statistically significant (-€3887 [-$4439]; P = .34). Conclusions and Relevance: In this economic evaluation, a CTR intervention with relapse prevention was likely to be cost-effective compared with center-based CR, suggesting that CTR maybe used as an alternative intervention for the treatment of patients with coronary artery disease. These results add to the evidence base in favor of CTR and may increase the implementation of CTR interventions in clinical practice.

Cost-effectiveness of secondary fracture prevention intervention for Medicare beneficiaries.

BACKGROUND: Secondary fracture prevention intervention such as fracture liaison services are effective for increasing osteoporosis treatment rates, but are not currently widely used in the United States. We evaluated the cost-effectiveness of secondary fracture prevention intervention after osteoporotic fracture for Medicare beneficiaries. METHODS: An individual-level state-transition microsimulation model was developed to evaluate the cost-effectiveness of secondary fracture prevention intervention compared with usual care for U.S. Medicare patients aged 65 and older who experience a new osteoporotic fracture. Patients who initiated pharmacotherapy and remained adherent were assumed to be treated for 5 years. Outcome measures included subsequent fractures, average lifetime costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios in 2020 U.S. dollars per QALY gained. The model time horizon was lifetime, and analysis perspective was payer. RESULTS: Base-case analysis results showed that the secondary fracture prevention intervention strategy was both more effective and less expensive than usual care-thus, it was cost-saving. Model findings indicated that the intervention would reduce the number of expected fractures by approximately 5% over a 5-year period, preventing approximately 30,000 fractures for 1 million patients. Secondary fracture prevention intervention resulted in an average cost savings of $418 and an increase in QALYs of 0.0299 per patient over the lifetime; for 1 million patients who receive the intervention instead of usual care, expected cost savings for Medicare would be $418 million dollars. One-way and probabilistic sensitivity analyses supported base-case findings of cost savings. CONCLUSION: Secondary fracture prevention intervention for Medicare beneficiaries after a new osteoporotic fracture is very likely to both improve health outcomes and reduce healthcare costs compared with usual care. Expansion of its use for this population is strongly recommended.

Long-Term Effects of an Intensive Prevention Program After Acute Myocardial Infarction.

Effective long-term prevention after myocardial infarction (MI) is crucial to reduce recurrent events. In this study the effects of a 12-months intensive prevention program (IPP), based on repetitive contacts between non-physician "prevention assistants" and patients, were evaluated. Patients after MI were randomly assigned to the IPP versus usual care (UC). Effects of IPP on risk factor control, clinical events and costs were investigated after 24 months. In a substudy efficacy of short reinterventions after more than 24 months ("Prevention Boosts") was analyzed. IPP was associated with a significantly better risk factor control compared to UC after 24 months and a trend towards less serious clinical events (12.5% vs 20.9%, log-rank p = 0.06). Economic analyses revealed that already after 24 months cost savings due to event reduction outweighted the costs of the prevention program (costs per patient 1,070 € in IPP vs 1,170 € in UC). Short reinterventions ("Prevention Boosts") more than 24 months after MI further improved risk factor control, such as LDL cholesterol and blood pressure lowering. In conclusion, IPP was associated with numerous beneficial effects on risk factor control, clinical events and costs. The study thereby demonstrates the efficacy of preventive long-term concepts after MI, based on repetitive contacts between non-physician coworkers and patients.

Single Visit Evaluation and Tympanostomy Tube Placement for the Treatment of Acute Otitis Media in Children.

OBJECTIVE: To review our experiences with development of a single visit surgery (SVS) program for children with recurrent acute otitis media (AOM) undergoing tympanostomy tube (TT) placement the same day as their otolaryngology surgical consultation. STUDY DESIGN: Retrospective cohort analysis. METHODS: Retrospective series of patients participating in SVS from inception March 1, 2014 to April 30, 2020 were analyzed, with attention to factors associated with increasing interest and participation in SVS and parent experiences/satisfaction. RESULTS: A total of 224 children had TT placed through SVS for AOM management. The average age of patients was 18.1 months (standard deviation 7.8 months), and 130 (58.0%) were male. The median interval between initial contact to schedule SVS, and the SVS date was 15 days (interquartile range 9-23 days). When analyzing year-over-year volumes from inception of SVS, notable increases were seen in 2016 and 2017 after a radio advertisement was played locally. A marked increase in volume was noted after implementation of a Decision Tree Scheduling (DTS) algorithm for children with recurrent AOM. Sixty-six (28.8%) procedures were performed after institution of DTS. A parent survey demonstrated high levels of satisfaction with the SVS experience. Estimations of savings to families in terms of time away from work demonstrated potential for indirect healthcare benefits. CONCLUSIONS: SVS for TT placement was a successful, alternative model of care for management of children with AOM. Marketing strategies regarding SVS, and the inclusion of SVS pathway in DTS platforms increased rates of interest and choice of this option. Parents of children undergoing TT through SVS were satisfied with the overall experience. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2823-2829, 2021.

Burden of oral anticoagulation in embolic stroke of undetermined source without atrial fibrillation.

OBJECTIVE: Prevention of recurrent stroke in patients with embolic stroke of undetermined source (ESUS) is challenging. The advent of safer anticoagulation in the form of direct oral anticoagulants (DOACs) has prompted exploration of prophylactic anticoagulation for all ESUS patients, rather than anticoagulating just those with documented atrial fibrillation (AF). However, recent trials have failed to demonstrate a clinical benefit, while observing increased bleeding. We modeled the economic impact of anticoagulating ESUS patients without documented AF across multiple geographies. METHODS: CRYSTAL-AF trial data were used to assess ischaemic stroke event rates in ESUS patients confirmed AF-free after long-term monitoring. Anticipated bleeding event rates (including both minor and major bleeds) with aspirin, dabigatran 150 mg, and rivaroxaban 20 mg were sourced from published meta-analyses, whilst a 30% ischaemic stroke reduction for both DOACs was assumed. Cost data for clinical events and pharmaceuticals were collected from the local payer perspective. RESULTS: Compared with aspirin, dabigatran and rivaroxaban resulted in 17.9 and 29.9 additional bleeding events per 100 patients over a patient's lifetime, respectively. Despite incorporating into our model the proposed 30% reduction in ischaemic stroke risk, both DOACs were cost-additive over patient lifetime, as the costs of bleeding events and pharmaceuticals outweighed cost savings associated with the reduction in ischaemic strokes. DOACs added £5953-£7018 per patient (UK), €6683-€7368 (Netherlands), €4933-€9378 (Spain), AUD$5353-6539 (Australia) and $26,768-$32,259 (US) of payer cost depending on the agent prescribed. Additionally, in the U.S. patient pharmacy co-payments ranged from $2468-$12,844 depending on agent and patient plan. In all settings, cost-savings could not be demonstrated even when the modelling assumed 100% protection from recurrent ischaemic strokes, due to the very low underlying risk of recurrent ischaemic stroke in this population (1.27 per 100 patient-years). CONCLUSIONS: Anticoagulation of non-AF patients may cause excess bleeds and add substantial costs for uncertain benefits, suggesting a personalised approach to anticoagulation in ESUS patients.

Cost-Utility Analysis of the Ontario Fracture Screening and Prevention Program.

BACKGROUND: The Fracture Screening and Prevention Program (FSPP), a fracture liaison service (FLS), was implemented in the province of Ontario, Canada, in 2007 to prevent recurrent fragility fractures and to improve post-fracture care. The objective of this analysis was to determine the cost-effectiveness of the current model of the FSPP compared with usual care (no program) from the perspective of the universal public health-care payer (Ontario Ministry of Health and Long-Term Care [MOHLTC]), over the lifetime of older adults who presented with a fragility fracture of the proximal part of the femur, the proximal part of the humerus, or the distal part of the radius and were not taking medications to prevent or slow bone loss and reduce the risk of fracture (bone active medications). METHODS: We developed a state-transition (Markov) model to conduct a cost-effectiveness analysis of the FSPP in comparison with usual care. The model simulated a cohort of patients with a fragility fracture starting at 71 years of age. Model parameters were obtained from published literature and from the FSPP. Quality-adjusted life-years (QALYs) and costs in 2018 Canadian dollars were predicted over a lifetime horizon using a 1.5% annual discount rate. Health outcomes included subsequent proximal femoral, vertebral, proximal humeral, and distal radial fractures. Scenario and subgroup analyses were reported. RESULTS: The FSPP had lower expected costs ($277 less) and higher expected effectiveness (by 0.018 QALY) than usual care over the lifetime horizon. Ninety-four percent of the 10,000 Monte Carlo simulated incremental cost-effectiveness ratios (ICERs) demonstrated lower costs and higher effectiveness of the FSPP. CONCLUSIONS: The FSPP appears to be cost-effective compared with usual care over a lifetime for patients with fragility fracture. This information may help to quantify the value of the FSPP and to assist policy-makers in deciding whether to expand the FSPP to additional hospitals or to initiate similar programs where none exist.

Icosapent Ethyl for Primary Versus Secondary Prevention of Major Adverse Cardiovascular Events in Hypertriglyceridemia: Value for Money Analysis.

BACKGROUND: Icosapent ethyl (IPE) is approved for the prevention of major adverse cardiovascular events (MACE) in patients with hypertriglyceridemia. However, due to budget constraints, access to IPE will inevitably be limited to a fraction of eligible patients. To help maximize value for money spent, we estimated the number of preventable MACE when providing IPE for primary versus secondary prevention. METHODS: The number of preventable MACE was estimated by dividing the available budget by the cost needed to treat (CNT) to prevent one MACE. CNT was calculated as the product of the number needed to treat (NNT) to prevent 1 MACE by therapy cost. NNT values were determined according to the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT) results. The budget limit was set as the United States' threshold suggested by the Institute for Clinical and Economic Review. Sensitivity analysis was performed regarding the cost of IPE in the United States. RESULTS: The NNT to prevent 1 MACE over 4.9 years in the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial primary prevention cohort was 59 (95% confidence interval [CI]: 24-∞) versus 14 (11-21) for secondary prevention. At an annual IPE cost of $2915, the CNT to prevent 1 MACE was $842,726 (95% CI: $342,804-∞) and $199,969 ($157,118-$299,953) accordingly. A total of $819 million worth of IPE can avoid 4762 MACE (95% CI: 0-11,707) versus 20,069 (13,379-25,541), when provided as primary versus secondary prevention therapy; P < .001. The number of avoided MACE is sensitive to IPE price. CONCLUSIONS: Prioritizing IPE therapy for patients with an established cardiovascular disease may provide significantly more value for money than primary prevention.

A fast and effective solution for ingrown toenail: Creation of a 2-mm space between tissue and nail by sutureless lateral longitudinal excision.

Nails have both functional and aesthetic importance. Undertreatments cause frequent recurrences affecting its functionality, while over-treatment spoils the aesthetic view. To describe the most practical and aesthetic method to treat ingrown toenail. All patients with ingrown toenail who applied to outpatient clinics of General Surgery Department between 2013 and 2019 were enrolled. A 2-mm space between tissue and nail by lateral longitudinal excision was created with only minimal matricectomy, under local anaesthesia. A total of 2334 surgical procedures were performed in 2118 patients. Recurrence rate was 1.7% during 36-month follow-up, most (70.7%) in younger men (22 years). The location of the lesions (right/left, medial/lateral or bilateral) did not show difference (p > 0.05 for each). Predisposing factors were tight-fitting footwear (4.5%), incorrect nail-trimming (3%), genetic tendency (2.8%), obesity (2.1%) and trauma (0.75%); but each was p > 0.05. Mean operation time was 3 min. There was no important complication, except hematoma (0.89%) and infection (0.68%). Mean healing time was 10 days and patients returned to daily activities in 3 days. Longitudinal excision with minimal matricectomy technique provides all dead tissue and diseased parts of nail and soft tissue to be removed. It is simple, cost-effective, satisfactory and aesthetic.

Cost-effectiveness analysis of rivaroxaban plus aspirin versus aspirin alone in secondary prevention among patients with chronic cardiovascular diseases.

PURPOSE: This study aimed to investigate the cost-effectiveness of low-dose rivaroxaban plus aspirin versus aspirin alone for patients with stable cardiovascular diseases in the Taiwan setting. METHODS: We constructed a Markov model to project the lifetime direct medical costs and quality-adjusted life-years of both therapies. Transitional probabilities were derived from the COMPASS trial, and the costs and utilities were obtained from the Taiwan National Health Insurance Database and published studies. One-way, scenario, subgroup, and probabilistic sensitivity analyses were performed to assess the uncertainty. Incremental cost-effectiveness ratio was presented as the outcome. The threshold of willingness-to-pay was set at US$76,368 (3 times the gross domestic product per capita of Taiwan). All analyses were operated by TreeAge 2019 and Microsoft Excel. RESULTS: The incremental cost-effectiveness ratios of rivaroxaban plus aspirin versus aspirin alone in the patients with stable cardiovascular diseases, coronary artery diseases, and peripheral artery diseases were US$83,459, US$69,852 and -US$13,823 per quality-adjusted life-year gained, respectively. The probabilistic sensitivity analyses showed that the probabilities of cost-effectiveness for the regimen with rivaroxaban among those with cardiovascular diseases and coronary artery diseases were 44.1% and 65.3% at US$76,368. CONCLUSION: Low-dose rivaroxaban plus aspirin is less likely to be a cost-effective alternative to aspirin in secondary prevention for the patients with stable cardiovascular diseases; however, among these patients, the regimen may have pharmacoeconomic incentives for the group merely having chronic coronary artery diseases from the Taiwan national payer's perspective. The pharmacoeconomic incentives are influenced by the drug price, event treatment fees, and willingness-to-pay threshold.

Cost-effectiveness of post-treatment follow-up examinations and secondary prevention of tuberculosis in a high-incidence setting: a model-based analysis.

BACKGROUND: In settings of high tuberculosis incidence, previously treated individuals remain at high risk of recurrent tuberculosis and contribute substantially to overall disease burden. Whether tuberculosis case finding and preventive interventions among previously treated people are cost-effective has not been established. We aimed to estimate costs and health benefits of annual post-treatment follow-up examinations and secondary preventive therapy for tuberculosis in a tuberculosis-endemic setting. METHODS: We developed a transmission-dynamic mathematical model and calibrated it to data from two high-incidence communities of approximately 40 000 people in suburban Cape Town, South Africa. We used the model to estimate overall cost and disability-adjusted life-years (DALYs) associated with annual follow-up examinations and secondary isoniazid preventive therapy (IPT), alone and in combination, among individuals completing tuberculosis treatment. We investigated scenarios under which these interventions were restricted to the first year after treatment completion, or extended indefinitely. For each intervention scenario, we projected health system costs and DALYs averted with respect to the current status quo of tuberculosis control. All estimates represent mean values derived from 1000 epidemic trajectories simulated over a 10-year period (2019-28), with 95% uncertainty intervals (UIs) calculated as the 2·5th and 97·5th percentile values. FINDINGS: We estimated that a single follow-up examination at the end of the first year after treatment completion combined with 12 months of secondary IPT would avert 2472 DALYs (95% UI -888 to 7801) over a 10-year period and is expected to be cost-saving compared with current control efforts. Sustained annual follow-up and continuous secondary IPT beyond the first year after treatment would avert an additional 1179 DALYs (-1769 to 4377) over 10 years at an expected additional cost of US$18·2 per DALY averted. Strategies of follow-up without secondary IPT were dominated (ie, expected to result in lower health impact at higher costs) by strategies that included secondary IPT. INTERPRETATION: In this high-incidence setting, post-treatment follow-up and secondary preventive therapy can accelerate declines in tuberculosis incidence and potentially save resources for tuberculosis control. Empirical trials to assess the feasibility of these interventions in settings most severely affected by tuberculosis are needed.

A computer-guided quality improvement tool for primary health care: cost-effectiveness analysis based on TORPEDO trial data.

OBJECTIVE: To assess the cost-effectiveness of a computer-guided quality improvement intervention for primary health care management of cardiovascular disease (CVD) in people at high risk. DESIGN: Modelled cost-effectiveness analysis of the HealthTracker intervention and usual care for people with high CVD risk, based on TORPEDO trial data on prescribing patterns, changes in intermediate risk factors (low-density lipoprotein cholesterol, systolic blood pressure), and Framingham risk scores. PARTICIPANTS: Hypothetical population of people with high CVD risk attending primary health care services in a New South Wales primary health network (PHN) of mean size. INTERVENTION: HealthTracker, integrated into health care provider electronic health record systems, provides real time decision support, risk communication, a clinical audit tool, and a web portal for performance feedback. MAIN OUTCOME MEASURES: Incremental cost-effectiveness ratios (ICERs): difference in costs of the intervention and usual care divided by number of CVD events averted with HealthTracker. RESULTS: The estimated numbers of major CVD events over five years per 1000 patients at high CVD risk were lower in PHNs using HealthTracker, both for patients with prior CVD events (secondary prevention; 259 v 267 with usual care) and for those without prior events (primary prevention; 168 v 176). Medication costs were higher and hospitalisation costs lower with HealthTracker than with usual care for both primary and secondary prevention. The estimated ICER for one averted CVD event was $7406 for primary prevention and $17 988 for secondary prevention. CONCLUSION: Modelled cost-effectiveness analyses provide information that can assist decisions about investing in health care quality improvement interventions. We estimate that HealthTracker could prevent major CVD events for less than $20 000 per event averted.

Cost-Effectiveness of Rifaximin Treatment in Patients with Hepatic Encephalopathy.

BACKGROUND: Hepatic encephalopathy (HE) is a complication of cirrhosis of the liver causing neuropsychiatric abnormalities. Clinical manifestations of overt HE result in increased health care resource utilization and effects on patient quality of life. While lactulose has historically been the mainstay of treatment for acute HE and maintenance of remission, there is an unmet need for additional therapeutic options with a favorable adverse event profile. Compared with lactulose alone, rifaximin has demonstrated proven efficacy in complete reversal of HE and reduction in the incidence of HE recurrence, mortality, and hospitalizations. Evidence suggests the benefit of long-term prophylactic therapy with rifaximin; however, there is a need to assess the economic impact of rifaximin treatment in patients with HE. OBJECTIVE: To assess the incremental cost-effectiveness of rifaximin ± lactulose versus lactulose monotherapy in patients with overt HE. METHODS: A Markov model was developed in Excel with 4 health states (remission, overt HE, liver transplantation, and death) to predict costs and outcomes of patients with HE after initiation of maintenance therapy with rifaximin ± lactulose to avoid recurrent HE episodes. Cost-effectiveness of rifaximin was evaluated through estimation of incremental cost per quality-adjusted life-year (QALY) or life-year (LY) gained. Analyses were conducted over a lifetime horizon. One-way deterministic and probabilistic sensitivity analyses were conducted to assess uncertainty in results. RESULTS: The rifaximin ± lactulose regimen provided added health benefits despite an additional cost versus lactulose monotherapy. Model results showed an incremental benefit of $29,161 per QALY gained and $27,762 per LY gained with rifaximin ± lactulose versus lactulose monotherapy. Probabilistic sensitivity analyses demonstrated that the rifaximin ± lactulose regimen was cost-effective ~99% of the time at a threshold of $50,000 per QALY/LY gained, which falls within the commonly accepted threshold for incremental cost-effectiveness. CONCLUSIONS: The clinical benefit of rifaximin, combined with an acceptable economic profile, demonstrates the advantages of rifaximin maintenance therapy as an important option to consider for patients at risk of recurrent HE.

Continual Long-Term Physiotherapy After Stroke: A Health Technology Assessment.

BACKGROUND: Stroke is a serious health issue in which an interruption in blood flow to any part of the brain damages brain cells. About 83% of people survive with substantial morbidity after their first stroke. We conducted a health technology assessment of continual long-term physiotherapy for people with a diagnosis of stroke, which included an evaluation of effectiveness, safety, cost-effectiveness, the budget impact of publicly funding continual long-term physiotherapy for people with a diagnosis of stroke, and patient preferences and values. METHODS: We performed a systematic literature search of the clinical evidence. We also performed a systematic literature search of the economic evidence. We did not conduct a primary economic evaluation because there was insufficient clinical evidence. We also analyzed the budget impact of publicly funding continual long-term physiotherapy after stroke in Ontario. To contextualize the potential value of continual long-term physiotherapy after stroke, we spoke with people who had been diagnosed with stroke, as well as their caregivers. RESULTS: We did not find any published studies that met the specific clinical inclusion criteria. We did not identify any studies that compared the cost-effectiveness of continual long-term versus short-term physiotherapy after stroke. The budget impact of publicly funding continual long-term physiotherapy after stroke in Ontario over the next 5 years ranges from $445,000 in year 1 at an uptake rate of 8% to $888,000 in year 5 at an uptake rate of 16%. The people who had been diagnosed with stroke with whom we spoke reported that they had benefitted from continual long-term physiotherapy. CONCLUSIONS: We did not identify studies that addressed the specific research question. Based on the clinical evidence review, we are unable to determine the benefits of continual long-term compared with short-term physiotherapy after stroke. The cost-effectiveness of continual long-term physiotherapy after stroke in Ontario is unknown. We estimate that publicly funding continual long-term physiotherapy after stroke in Ontario would result in additional costs of between $445,000 and $888,000 annually over the next 5 years. Patients and caregivers who we spoke with felt that patients who have experienced a stroke should be able to continue with physiotherapy.

Successful implementation of a Fracture Liaison Service through effective change management: a qualitative study.

We assessed the context in which a hip Fracture Liaison Service was implemented. We conducted semi-structured interviews with 21 key informants at two time points to understand organizational readiness, facilitators, and barriers to change. We identified strategies important to successful implementation, particularly in the context of change fatigue. PURPOSE: Fracture Liaison Service (FLS) is effective for secondary fracture prevention. Two hospital sites implemented FLS for hip fracture patients, 50 + years, in Alberta, Canada. We assessed organizational readiness, facilitators, and barriers to change to better understand the context in which the FLS was implemented to inform its potential spread provincially. METHODS: We recruited individuals involved in FLS implementation at provincial and site levels to participate in telephone interviews at baseline and 16 months post-implementation. Interviews were transcribed and analyzed using thematic content analysis. In addition, site-level participants were invited to complete the Organizational Readiness to Implement Change tool at baseline. RESULTS: We conducted 33 semi-structured interviews (20 at baseline; 13 at post-implementation) with 21 key informants. Participants included managers (24%), FLS physicians/clinical nurses (19%), operational/leadership roles (19%), physicians/surgeons (14%), pharmacists (10%), nurse practitioners (10%), and social work (5%). Seventeen site-level participants completed the ORIC tool at baseline; all participants scored high (71%) or neutral (29%). We found that the use of several strategies, including demonstrating value, providing resources, and selecting appropriate sites, were important to implementation, particularly in the context of change fatigue. Participants perceived the FLS as acceptable and there was evidence of facilitated learning rather than simply monitoring implementation as intended. CONCLUSIONS: An effective change management approach neutralized change fatigue. This approach, if maintained, bodes well for the potential spread of the FLS provincially if proven effective and cost effective. Change readiness assessment tools could be used strategically to inform the spread of the FLS to early adopter sites.

Cost-effectiveness of statin therapy for secondary prevention among patients with coronary artery disease and baseline LDL-C 70-100 mg/dL in Taiwan.

BACKGROUND: The recommended target low-density lipoprotein cholesterol (LDL-C) level for coronary artery disease (CAD) patients has been lowered from 100 to 70 mg/dL in several clinical guidelines for secondary prevention. We aimed to assess whether initiating statin treatment in CAD patients with baseline LDL-C 70-100 mg/dL in Taiwan could be cost-effective. METHODS: A Markov model was developed to simulate a hypothetical cohort of CAD patients with a baseline LDL-C level of 90 mg/dL. The incidence and recurrence of MI and stroke related to specific LDL-C levels as well as the statin effect, mortality rate, and health state utilities were obtained from the literature. The direct medical costs and rate of fatal events were derived from the national claims database. The incremental cost-effectiveness ratio (ICER) per quality-adjusted life years (QALYs) was calculated, and sensitivity analyses were performed. RESULTS: Moderate-intensity statin use, a treatment regimen expected to achieve LDL <70 mg/dL in the base case, resulted in a net gain of 562 QALYs but with an additional expenditure of $11.4 million per 10,000 patients over ten years. The ICER was $20,288 per QALY gained. The probabilities of being cost-effective at willingness-to-pay thresholds of one and three gross domestic product per capita ($24,329 in 2017) per QALY were 51.1% and 94.2%, respectively. Annual drug cost was the most influential factor on the ICER. CONCLUSION: Lowering the target LDL-C level from 100 to 70 mg/dL among treatment-naïve CAD patients could be cost-effective given the health benefits of preventing cardiovascular events and deaths.
