Cost-Effectiveness Rivaroxaban versus Enoxaparin for Prevention of Venous Thromboembolism after Knee Replacement Surgery in Iran.

Background: The highest risk of developing venous thromboembolism (VTE) is seen in patients who have undergone orthopedic surgery. One of the most common methods to reduce the risk of thromboembolism in these patients is anticoagulant prophylaxis. Rivaroxaban is one of the anticoagulants that has a lower cost than other anticoagulants and has a significant effect on people's quality of life as it is edible. The study aimed to determine the cost-effectiveness of rivaroxaban as compared with enoxaparin for venous thromboembolism prophylaxis in knee replacement patients in Iran. Methods: It was a quantitative and economic evaluation study with a cost-effectiveness approach and an applied study because its results could be used directly for policy-making and decision-making in the health system. The study was conducted in 2019 and 2020. This study considered the health system perspective. The study population included all knee replacement patients. The sample included 203 patients referred to Shafa Yahyaeian Hospital and 300 patients referred to Rasoul Hospital in Tehran. The study was conducted in two steps. A systematic review of studies was conducted in the first step. The CHEERS checklist was used to evaluate the quality of the studies in the systematic review. The EQ-5D questionnaire was used in the second step to calculate the QALY, and the cost collection form was used to calculate the direct medical cost. The data were analyzed through a decision tree, and Stata and Tree age pro softwares were the analysis tools. Also, according to the per capita GDP index for Iran in 2018, the incremental cost-effectiveness threshold was considered to be $10,000. Results: The results of this study showed that during the prophylaxis period, rivaroxaban was one and a half times less costly than enoxaparin. Quality of life in uncomplicated conditions were 0.85 QALY for rivaroxaban and 0.69 QALY for enoxaparin. Based on the results of this study, the cost of rivaroxaban during the prophylaxis was $ 160.97 and the quality of life was 0.85 QALY and the cost of enoxaparin was $ 276.07 and the quality of life was 0.69 QALY. The cost difference between the two interventions was $ 115.09 and the outcome difference was 0.16 QALY. The incremental cost-effectiveness ratio was $ 189.40 for rivaroxaban and $ 416.28 for enoxaparin. According to the results of this study, rivaroxaban reduced the duration of hospitalization by an average of 2 days in asymptomatic patients (prophylaxis period) compared to enoxaparin. Conclusion: Rivaroxaban, an oral medication, reduced costs and increased the quality of life in people undergoing knee replacement surgery compared with an enoxaparin injection vial. This drug was less costly for the patient and health systems and its use was cost-effective as a thromboprophylaxis drug following knee replacement surgery.

Economic Evaluation of Palliative Care for Patients with Cancer Disease: A Systematic Review.

Background: With the increase in the population of cancer patients and the importance of reducing the economic burden of disease, it is very important to offer solutions that can provide the services needed by this group of patients in the most appropriate way. In recent years, palliative care services have been provided in a wide range of countries for this purpose, and many studies have been conducted to assess its economic and clinical aspects. The current study aimed to systematically review economic evaluation studies that investigate the costs of end-of-life care for cancer patients. Methods: Electronic search was performed in multiple databases and different resources between 2000-2021 based on inclusion and exclusion criteria. Inclusion criteria were Studies consisting of a complete EE, including CEA, CUA, and CBA regarding the EE of palliative care for patients with cancer disease, EE studies carried out by decision analysis models following the EE approach, full-text articles in the English language, and published during 2000 and 2021 and According to our search strategy, the following articles were removed: studies conducted as a partial EE (like those intended to evaluate the effectiveness, cost evaluation, QoL evaluation), articles with poor methodological quality based on the CHEERS checklist, non-English studies, study protocols, articles presented to a conference, and letters to the editor. The quality of the articles was evaluated using a CHEERS checklist. Results: 29 studies were included based on inclusion criteria. Most articles were published during the past decade. All studies were performed in high-income countries (UK= 6 studies, Canada= 5 studies). Most studies (n=7) focused on the health sector. Results of quality evaluation showed that 10 articles had excellent quality (score higher than 85%). Most studies (27 out of 29 studies) concluded that palliative medicine interventions were cost-effective and yielded positive cost-effectiveness results. 20 studies confidently concluded about the costs and benefits of providing palliative care services on cost-effectiveness and cost savings, and 2 studies made such a conclusion with uncertainty. Therefore, palliative care for cancer patients is cost-effective or cost-saving in 85% of studies. Conclusion: Although there are a wide variety of studies, characteristics, and quality of the final studies included in the present study, there are relatively favorable and stable patterns regarding the results. Palliative care is usually less expensive than comparator groups, and the cost difference is statistically significant in most cases, and this treatment is a relatively cost-effective option. However, making the right relevant decision and applying it as a dominant therapy approach in different countries requires further study in larger populations and over a longer period.

Economic evaluation of ivabradine in treatment of patients with heart failure: a systematic review.

BACKGROUND: Chronic heart failure (CHF) is a clinical status and a progressive health disorder extremely related to increased morbidity and mortality worldwide. Accordingly, this study aimed to assess systematic review of literature on cost-effectiveness done in patients with heart failure receiving Ivabradine plus standard treatment compared with standard treatment alone. AREAS COVERED: This study is a systematic review in which all published articles related to the study topic were assessed in time range of 2014-2020. In order to find articles, internet search in foreign databases of PubMed, Embase, ISI/Web of Science (WoS), SCOPUS, Global Health databases, through keywords related to the objective was performed. Six articles out of 1524 article related to final topic were assessed. In addition, quality of studies was evaluated using CHEERS checklist. In six countries investigated (Iran, Thailand, Australia, United States of America, United Kingdom, and Greece), willingness-to-pay (WTP) thresholds higher cost per QALY, and highest ICER for Ivabradine was in USA (55,600 $/QALY) and the lowest was in Thailand (10,616$/QALY). Most items of CHEERS were estimated in the studies and studies had good quality. EXPERT OPINION: Regarding our investigation, ivabradine combined with standard care was more cost-effective than standard care alone in most of the evaluated studies, although the cost of this intervention was higher than its effectiveness. However, the threshold chosen by each country can have a significant impact on these results. And to have a more accurate result, it is required to pay more attention to the income level in different countries.

The Economic Burden of Cancer in Iran during 1995-2019: A Systematic Review.

BACKGROUND: Cancer is the third cause of death following cardiovascular disease and accidents, in Iran. The purpose of this study was to systematically review the economic burden of cancer studies in Iran. METHODS: This systematic review examined the types of direct medical and non-medical costs and indirect costs in cancer patients and includes studies in English and Persian that were reviewed in Scopus, Web of science, SID, Iranmedex, Magiran and databases of Medline, etc., from 1995-2019. RESULTS: Twenty-one articles were included. Most studies have examined the direct costs of all types of cancers. The articles reviewed different types of cancer, such as prostate cancer (n=2), colorectal cancer (n=2), breast cancer (n=4), gastric cancer (n=2), oral and pharyngeal cancer (n=1), lung cancer (n=3), and blood cancer (n=4). The great number of studies were related to the gastrointestinal, breast and blood cancers. The gastrointestinal (gastric and colorectal) and breast cancer had the major economic burden than others. CONCLUSION: It is necessary that special attention to patients, supportive measures to reduce the share of costs, and more budget allocation for prevention, screening and early detection being at priorities in the health system planning.

Social Determinant of Mental Health in Immigrants and Refugees: A Systematic Review.

Background: Refugees are the most vulnerable to mental health problems of all migrant groups. Epidemiological studies measuring the prevalence of mental health disorders in resettled refugee populations have found high rates of psychiatric disorders, including post-traumatic stress disorder (PTSD), depression, and anxiety. To investigate the evidence of Social Determinant of Mental Health in Immigrants and Refugees Methods: We searched PubMed, Web of Science, Embase, Scopus, Cochrane Library, and ProQuest databases electronically. The interval selected for searching articles was between 2000-2021. After selecting articles based on inclusion and exclusion criteria, data were extracted, and the results were summarized. Results: Among 306 initial studies, 11 studies were the inclusion criteria. In these studies, the target population was people who had immigrated to countries or become refugees for various reasons. In 7 of 11 studies, social factors affecting the mental health of refugees were examined. In four studies, these factors were examined in immigrants. In most studies, social determinants of mental health were common among refugees and migrants. Conclusion: Improving each of the determinants of health plays an important role in increasing the level of mental health of immigrants and refugees.

Economic Evaluation of Rivaroxaban Versus Enoxaparin for Prevention of Venous Thromboembolism After Total Knee Replacement and Total Hip Replacement: A Systematic Review.

BACKGROUND: Deep vein thrombosis (DVT) and pulmonary embolism (PE) together are called venous thromboembolism (VTE) and impose a high economic burden on healthcare systems. Thousands of people are hospitalized annually due to benign and treatable diseases but die due to PE; with the adoption of appropriate prevention, these deaths can be prevented. OBJECTIVE: To investigate the cost-effectiveness of using rivaroxaban versus enoxaparin in published economic analyses for prevention of VTE after total knee (TKR) or hip replacement (THR). METHOD: In a systematic review electronic searches were performed on various online databases, including PubMed, Web of science, Embase, Scopus, Health Economic Evaluations Database (HEED), and ProQuest. The inclusion criteria were: studies that were conducted on the cost-effectiveness of rivaroxaban versus enoxaparin for the prevention of VTE after TKR and THR; cost-effectiveness studies conducted using decision analysis models based on the economic evaluation approach; studies with available full-text papers; and studies written in English and published between 2007 and 2019. The exclusion criteria were: studies with partial cost effectiveness (such as effectiveness assessment, cost assessment, quality-of-life assessment); studies written in languages other than English; and all protocols, conference abstracts, and letters to the editor. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist was used to qualitatively evaluate the studies. RESULTS: Of a total of 537 initial studies, nine papers met the inclusion criteria. The time scope of studies ranged from 3 months to 5 years. Among the selected studies, some studies had included discount rates (n = 4) and the other studies did not utilize discount rates and were set to zero percent by default (n = 5). In all studies, direct medical costs, including costs related to the prevention, diagnosis, and treatment of VTE and PE, and management and monitoring of treatment costs were reviewed. CONCLUSION: The results of this systematic review showed that using rivaroxaban in patients undergoing total knee or hip replacement reduced costs and increased quality of life. However, since most of the studies had been conducted in developed countries, it is not possible to generalize the results to developing countries. Nonetheless, given that rivaroxaban is administered orally and does not require continuous monitoring, it will be less costly for patients and health systems and is more appropriate to administer it as a thromboprophylactic drug following total knee or hip replacement surgery.

Economic burden of osteoporosis in the world: A systematic review.

Background: Osteoporosis is a skeletal disease that is associated with a reduction in bone mass and microstructures and deterioration of bone tissue. It is also associated with an increased risk of fracture that is the most important complication of osteoporosis. The knowledge about costs and economic aspects of osteoporosis plays an important role in making policies and planning measures for the prevention and management of this disease; hence, this study systematically investigated the available evidence on the costs associated with osteoporosis worldwide. Methods: In this systematic review, electronic searches were performed on various online databases, including PubMed, Embase, Scopus, web of science, ProQuest, and Cochrane. The timeframe selected for searching articles was from 1980 to 2018. Results: Of a total of 1989 papers, 28 papers were included in the study on the basis of inclusion criteria. Based on the data extracted from the mentioned studies, the mean age of people with osteoporotic fractures was 50 years, with the highest costs associated with hip fractures. Conclusion: Our review indicated that the cost of osteoporosis carries a significant economic burden on countries in the world. The main cost drivers in this study were Fracture-related costs. The direct annual cost of treating osteoporotic fractures of people on average is reported to be between 5000 and 6500 billion USD in Canada, Europe and the USA alone, not taking into account indirect costs such as disability and loss of productivity. Prevention of this disease can significantly reduce the costs incurred by the health system.

Economic evaluation of the utilization of telemedicine for patients with cardiovascular disease: a systematic review.

Cardiovascular disease is one of the major causes of mortality in the world, with high human and financial burdens on communities. Telemedicine is a tool for providing services for patients that are difficult to access or in need of immediate care. The aim of this study was to systematically review economic evaluation studies that compared telemedicine with usual care for cardiovascular patients. A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and related articles published up to December 2018 were searched in different databases (PubMed, Embase, SCOPUS, Global Health, Google Scholar, Magiran, SID). The articles were selected based on inclusion and exclusion criteria. Consolidated health economic evaluation reporting standards statement checklist was used to qualitatively evaluate the papers. Overall, 20 articles were included in the study. The studies used quality-adjusted life years to measure outcomes. The highest and lowest values of Incremental Cost-effectiveness Ratio were $515,082 and $2099 that had been reported in the UK and New Zealand, respectively. Most of the items of the checklist were reported and the quality of most of the studies was excellent and very good. According to the results, telemedicine improves the clinical outcomes and results in considerable saving in costs. Utilizing telemedicine concurrent with the usual care for service delivery is more cost-effective. The reviewed studies had been conducted in high-income countries, hence, it is essential to be cautious when generalizing the results and applying them in health systems policymaking.
