RESUMO

BACKGROUND: This study aimed to estimate the economic impact of replacing the current Peruvian primary immunization scheme for infants under 1 year old with an alternative scheme with similar efficacy, based on a hexavalent vaccine. METHODS: A cost-minimization analysis compared the costs associated with vaccine administration, adverse reactions medical treatment, logistical activities, and indirect social costs associated with time spent by parents in both schemes. A budgetary impact analysis assessed the financial impact of the alternative scheme on healthcare budget. RESULTS: Incorporating the hexavalent vaccine would result in a 15.5% net increase in healthcare budget expenditure ($48,281,706 vs $55,744,653). Vaccination costs would increase by 54.1%, whereas logistical and adverse reaction costs would be reduced by 59.8% and 33.1%, respectively. When including indirect social costs in the analysis, the budgetary impact was reduced to 8.7%. Furthermore, the alternative scheme would enable the liberation of 17.5% of national vaccines storage capacity. CONCLUSIONS: Despite of the significant reduction of logistical and adverse reaction costs, including the hexavalent vaccine into the National Immunization Program of Peru in place of the current vaccination scheme for infants under 1 year of age would increase the public financial budget of the government as it would represent larger vaccine acquisition costs. Incorporating the indirect costs would reduce the budgetary impact demonstrating the social value of the alternative scheme. This merits consideration by government bodies, and future studies investigating such benefits would be informative.

RESUMO

Aims: Cost-minimization analysis (CMA) comparing the teledermatology service of the State of Santa Catarina, Brazil with the provision of conventional care, from the societal perspective. Patients & methods: All costs related to direct patient care were considered in calculation of outpatient costs. The evaluation was performed using the parameters avoided referrals and profile of hospitalizations. The economic analysis was developed through a decision tree. Results: Totally, 40% of 79,411 tests performed could be managed in primary care, avoiding commuting and expanding the patients' access. The CMA showed the teledermatology service had a cost per patient of US$196.04, and the conventional care of US$245.66. Conclusion: In this scenario, teledermatology proved to be a cost-saving alternative to conventional care, reducing commuting costs.

Lay abstract Diagnosis and treatment of skin diseases through teledermatology avoid patient referrals, improves accessibility to specialized care, as well as the skin care provided by physicians. This study compared the costs of the teledermatology service of the State of Santa Catarina, Brazil with the costs of the provision of conventional care, to check which of them was more efficient. All costs related to direct patient care were considered in the calculation of costs. Totally, 40% of 79,411 dermatological tests performed could be locally managed in primary care, avoiding commuting, and expanding the patients' access to care. The teledermatology service had a cost per patient of US$196.04, compared with the cost of conventional care of US$245.66. In this evaluation, teledermatology proved to be cheaper than conventional care, reducing commuting costs.

RESUMO

BACKGROUND: Malignant pleural mesothelioma (MPM) is rare and aggressive neoplasia, with a poor prognosis; furthermore, the monetary cost of its treatment represents a major challenge for many patients. The economic burden this malignancy imposes is underscored by the fact that asbestos exposure, which is the most frequent risk factor, is much more prevalent in the lower socioeconomic population of developing countries. The aims of the present study were to evaluate the efficacy, safety, and cost of continuous infusion of low-dose Gemcitabine plus Cisplatin (CIGC) as a treatment strategy for patients with unresectable MPM. METHODS: We performed a prospective cohort study to determine efficacy and safety of continuous infusion gemcitabine at a dose of 250 mg/m2 in a 6-h continuous infusion plus cisplatin 35 mg/m2 on days 1 and 8 of a 21-day cycle in patients with unresectable MPM. We also performed a cost-minimization analysis to determine if this chemotherapy regimen is less expensive than other currently used regimens. RESULTS: The median number of chemotherapy cycles was six (range 1-11 cycles); objective response rate was documented in 46.2%, and disease control rate was seen in 81.2%. Median PFS was 8.05 months (CI 95% 6.97-9.13); median OS was 16.16 months (CI 95% 12.5-19.9). The cost minimization analysis revealed savings of 66.4, 61.9, and 97.7% comparing CIGC with short-infusion gemcitabine plus cisplatin (SIGC), cisplatin plus pemetrexed (CP), and cisplatin plus pemetrexed and bevacizumab (CPB), respectively. Furthermore, this chemotherapy regimen proved to be safe at the administered dosage. CONCLUSION: CIGC is an effective and safe treatment option for patients with unresectable MPM; besides, this combination is a cost-saving option when compared with other frequently used chemotherapy schemes. Therefore, this treatment scheme should be strongly considered for patients with unresectable MPM and limited economic resources.

RESUMO

BACKGROUND: In 2020 Colombia may expect to have close to 231,700 patients with neovascular age-related macular degeneration (ARMD). Treatment of neovascular ARMD involves the sequential Intra-vitreal injections of anti-vascular endothelial growth factor (anti-VEGF therapy) medications. The efficacy and safety of anti-VEGF therapy on a treat-and-extend (T&E) dosing scheme are similar when ranibizumab or aflibercept are administered. Objective : A cost-minimization analysis from the payer`s perspective in Colombia projects treatment expenses of anti-VEGF therapy using aflibercept or ranibizumab on T&E regimens for the treatment of neovascular ARMD. Methods : A model projects the expenses of the compared treatment regimens for two and five-year periods beginning on February 2020. The model used information from clinical trials, case series and meta-analyses on the compared treatment regimens, demographic, epidemiologic and economic data originated from the Colombian government sources. A 3% discount rate was applied. Results : Projected cost differences in favor of ranibizumab after two and five-year treatment periods beginning February 2020 could be close to U.S. $ 4,861 and U.S $ 7,241 per treated eye, respectively. If all patients with unilateral and bilateral neovascular ARMD in Colombia were to receive appropriate anti-VEGF therapy for two years, the projected expected cost difference in favor of ranibizumab could be close to U.S. $ 462,717,092 dollars. Conclusion : Within the Colombian healthcare setting anti-VEGF therapy on a T&E regimen utilizing ranibizumab for neovascular ARMD may be cost-saving compared with employing aflibercept. Despite cost favorability, ranibizumab should not be the only therapeutic option since in clinical practice alternatives are required.

RESUMO

ABSTRACT Introduction: Cytomegalovirus may cause severe disease in immunocompromised patients. Nowadays, quantitative polymerase chain reaction is the gold-standard for both diagnosis and monitoring of cytomegalovirus infection. Most of these assays use cytomegalovirus automated molecular kits which are expensive and therefore not an option for small laboratories, particularly in the developing world. Objective: This study aimed to optimize and validate an in-house cytomegalovirus quantitative polymerase chain reaction test calibrated using the World Health Organization Standards, and to perform a cost-minimization analysis, in comparison to a commercial cytomegalovirus quantitative polymerase chain reaction test. Study design: The methodology consisted of determining: optimization, analytical sensitivity, analytical specificity, precision, curve variability analysis, and inter-laboratorial reproducibility. Patients (n = 30) with known results for cytomegalovirus tested with m2000 RealTime System (Abbott Laboratories, BR) were tested with the in-house assay, as well as patients infected with other human herpes virus, in addition to BK virus. A cost-minimization analysis was performed, from a perspective of the laboratory, assuming diagnostic equivalence of the methodologies applied in the study. Results: The in-house assay had a limit of detection and quantification of 60.3 IU/mL, with no cross-reactivity with the other viral agents tested. Moreover, the test was precise and had a R 2 of 0.954 when compared with the m2000 equipment. The cost analysis showed that the assay was economically advantageous costing a median value of 37.8% and 82.2% in comparison to the molecular test in use at the hospital and the m2000 equipment, respectively. Conclusions: These results demonstrated that in-house quantitative polymerase chain reaction testing is an attractive alternative in comparison to automated molecular platforms, being considerably less expensive and as efficacious as the commercial methods.
