Background: Community pharmacists play an important role in improving outcome by providing advice and counselling services to patients. Objectives: The aim of this study was to measure the willingness to pay (WTP) for pharmacist counselling services in community pharmacies and identify determinant factors on consumers’ WTP. Methods: A self-administered questionnaire-based survey was conducted in community pharmacies in Tehran (capital of Iran) from January 1, 2020 to February 20, 2021. Contingent valuation method was applied to evaluate respondents’ maximum WTP using three hypothetical scenarios illustrating different levels of counselling services. Logistic regression was used to analyze the association between different variables and WTP for pharmacy services. Results: Total number of participants who completed the questionnaire were 332 and 60% of the participants were male. In the first scenario 70.2% of participants were willing to pay for oral counselling pharmacy services. In the second and third scenario, percentage of people willing to pay increased to 79.5%. and 86.1%, respectively. In the first scenario, monthly income (OR = 0.041, P value = 0.04), the duration of underlying illness (OR = 0.04, P value = 0.04) and the using internet (OR = 2.59, P value = 2.59) had a statistically significant relationship with willingness to pay. In the third scenario, the willingness to pay increased as the age decreased. The possibility of using the internet (OR = 3.32, P value = 0.00) and the need for a community pharmacist (OR = 2.19, P value = 0.03) increased the chance of willingness to pay. Conclusions: More consumers are willing to pay for more pharmacist counselling services. Therefore, improving the quality of counselling services could have positive economic effects on community pharmacies.

Background: Hemophilia A (HA) is an inherited X-linked bleeding disease with costly treatment, especially for high titer inhibitory patients. Emicizumab, a new humanized bispecific antibody, has been approved for use to prevent or reduce the frequency of bleeding episodes in HA patients with inhibitors. This study evaluated the cost-utility of emicizumab prophylaxis (EP) in comparison with recombinant factor VII activated on-demand treatment in HA patients with inhibitors. Methods: A life-time Markov model with payer and societal perspectives was developed in different age groups with different annual bleeding rates (ABR). Efficacy of treatments were extracted from HAVEN trials. Utilities were retrieved from published evidence. Costs were calculated based on Iran food and drug administration official website, national tariff book for medical services and hospital data. One-way deterministic sensitivity analysis was performed. Results: EP was dominant choice in comparison with on-demand administration of recombinant factor VII activated in all age groups with ABR 20 and 25, and it remained dominant in patients with age 2 and age 12 at start point with ABR 16 and 17. The reported incremental cost-effectiveness ratio for the group with ABR 18 at the age 20, was 12,936 United States Dollars which is lower than the acceptable threshold of cost-effectiveness in Iran (1–3 gross domestic product per capita) and EP can be considered as cost-effective choice in this scenario. Conclusion: EP was found to be a dominant and cost-effective choice for Iranian HA patients with factor VIII inhibitors with ABR 18 and above with considerable cost saving.

Objectives: Thalassemia is a hereditary disease, which caused economic burden in developing countries. This study evaluated the cost utility of new formulation of deferasirox (Jadenu) vs deferoxamine (Desferal) among B-Thalassemia-major patients from payer perspective in Iran. Methods: An economic-evaluation through Markov model was performed. A systematic review was conducted in order to evaluate the clinical effectiveness of comparators. Because of chelating therapy is weight-dependent, patients were assumed to be 2 years-old at initiation in first and 18 years-old in second scenario, and model was estimated lifetime costs and utilities. Costs were calculated to the Iran healthcare system through payer perspective and measured effectiveness using quality-adjusted life years (QALYs). One-way sensitivity analysis and budget impact analysis was also employed. Results: The 381 studies were retrieved from systematic searching through databases. After eliminating duplicate and irrelevant studies, 2 studies selected for evaluating the effectiveness. Jadenu was associated with an incremental cost-effectiveness ratio (ICER) of 1470.6 and 2544.7 US$ vs Desferal in first and second scenario respectively. The estimated ICER for Jadenu compared to generic deferoxamine was 2837.0 and 6924.1 US$ for first and second scenario respectively. For all scenarios Jadenu is presumed as cost-effective option based on calculated ICER which was lower than 1 gross domestic product per capita in Iran. Sensitivity analysis showed that different parameters except discount rate and indirect cost did not have impact on results. Based on budget impact analysis the estimated cost for patients using Desferal (based on the market share of brand) was 44,021,478 US$ in 3 years vs 42,452,606 US$ in replacing 33% of brand market share with Jadenu. This replacement corresponded to the cost saving of almost 1,568,872 US$ for the payers in 3 years. The calculated cost of using generic deferoxamine in all patients was 68,948,392 US$. The increase in the cost of using Jadenu for 10% of all patients in this scenario would be 934,427 US$ (1.36%) US$ at the first year. Conclusions: Based on this analysis, film-coated deferasirox appeared to be cost-effective treatment in comparison with Desferal for managing child and adult chronic iron overload in B-thalassemia major patients of Iran.

Benign prostatic hyperplasia is a common chronic disease that is age-dependent. There are two main types of interventional treatment, transurethral resection of prostate as a gold standard (TURP) and open prostatectomy (OP); also, there are two pharmacological groups for managing BPH: alpha-blockers and 5-alpha-reductase inhibitors (5-ARIs). In this economic evaluation study, one 5-ARIs, dutasteride and two main surgical treatments are compared as alternatives for treating moderate BPH in Iran. A cost-utility study with an Iranian health provider perspective was conducted. Markov model in a cohort of 1000 patients with BPH with annual cycle length and ten years’ time horizon was developed by using MS EXCEL 2013. The effectiveness measure was an improvement in the IPSS score and transformed to the utility. The transition probabilities, utilities and adverse events were extracted from published clinical trials. The direct medical costs were measured in the 2017 US Dollar. One way sensitivity analysis and scenario analysis were conducted.For treating moderate BPH, seventy-year-old men, in the base case scenario, the utility of pharmacotherapy is 18 QALY less than surgery, and the cost of pharmacotherapy is 136,301.1 $ less than surgery. ICER for pharmacotherapy was 7,572.3 $ compared to surgery. In the sensitivity analysis, the model is not sensitive to most variables but the unit cost of dutasteride. Based on scenario analysis conducted for different age groups, pharmacotherapy with dutasteride is preferred to surgery in patients over 60 years of age in Iran. However, for younger adult men between 40-60 years old, surgery is a cost-effective alternative.

Background: Migraine is a prevalent, chronic neurovascular disorder that incurs significant indirect costs due to productivity loss. Preventive therapy is an effective way to alleviate the societal and healthcare burden of migraine. Approximately 14% of both the global and Iranian populations are affected by migraine, which has substantial economic implications. Objectives: To determine the cost-effectiveness of Erenumab compared to Topiramate for migraine treatment in Iran. Methods: A three-state Markov model was used to evaluate the cost-effectiveness of Erenumab. The model considered both direct and indirect costs from a societal perspective. The incremental cost-effectiveness ratio (ICER) was calculated by determining the cost per quality-adjusted life year (QALY) gained. Costs and QALYs were discounted annually at 5.8% and 5%, respectively. Deterministic and probabilistic sensitivity analysis (PSA) were performed to assess the robustness of the model. Results: The average cost for patients using the Erenumab strategy was 16,836 USD over five years, whereas the average cost for the Topiramate strategy was estimated to be 2,660 USD. Additionally, the average QALYs for the Erenumab and Topiramate strategies were 3.64 and 3.46, respectively. The ICER for the Erenumab strategy was 78,923 USD/QALY. This ICER is significantly higher than the fixed Iranian willingness-to-pay (WTP) threshold of 2,456 USD. Conclusions: The study concludes that preventive treatment of migraine with Erenumab, compared to Topiramate, is not cost-effective in Iran based on current prices. Therefore, for Erenumab to be considered cost-effective, a significant price reduction is necessary for its entry into the Iranian pharmaceutical market.

Background and purpose: Plaque psoriasis is a chronic inflammatory disease with skin manifestations that affect the patients’ quality of life negatively. The prevalence of psoriasis is approximately 2-3% worldwide and appears to be still on the increase. Due to the stigma problems, psoriasis has a significant effect on one’s life that is often overlooked. The current study aimed to conduct the cost-utility evaluation and budget impact analysis of adding-on apremilast ahead of biologic therapy in the treatment of moderate to severe plaque psoriasis. The psoriatic patients who did not undergo the conventional systemic therapy were eligible to enter the defined sequences. Experimental approach: An excel-based Markov model with 40 cycles of 3 months, each of which was adopted to compare the outcomes of each exclusively administered sequence in the treatment of moderate to severe plaque psoriasis. Two exclusive therapeutic sequences were considered. In the first sequence, apremilast was followed by biologics and in the second one, biologics were administered initially without apremilast. The results were extrapolated up to 10 years. The designed Markov model was also used in budget impact analysis. The cost-saving potential of the new treatment was accounted for the next 5 years. Findings/Results: Incremental cost and incremental effect were reported in the base case scenario. Using the sequence consisting apremilast provided an additional 0.10 quality-adjusted life years and decreased total costs by about 11,100 USD per patient. These results were in line with the findings from sensitivity analysis. The cost-saving over 5 years is estimated to be around 30 million dollars for the Iran market following the use of the new treatment. Conclusion and implications: In the treatment of moderate to severe plaque psoriasis, apremilast supplementation prior to biological treatments is more cost-effective than biological treatment alone.
