Abstract
OBJECTIVE To assess the efficiency of Dyevert™ Power XT compared to the standard clinical practice when used for percutaneous coronary interventions (PCI). METHODS A Markov model was developed to estimate, over 3-month cycles and a lifetime time horizon, the cumulative costs and health outcomes (life years gained [LYG] and quality-adjusted life years [QALY]) in a hypothetical cohort of 1,000 patients with chronic kidney disease (CKD) 3b-4 and an average age of 72 years. The incidence of contrast-induced acute kidney injury for these patients is 18.89% in routine practice and 7.78% with Dyevert. QALYs were estimated by applying utilities by health state. Transitions between states and utilities were obtained from the literature. Overall all-cause and state-specific mortality were considered. The total cost (€2,022) estimated with the National Health System perspective included cost of the procedure and of CKD management. The parameters were validated by a panel of experts. A discount rate (3% per year) was applied to costs and outcomes. RESULTS The use of Dyevert yielded more health benefits (34.60 LYG and 5.69 QALYs) compared to the current standard practice (33.11 LYG and 5.38 QALYs). Lifetime cost accumulated at the end of the simulation resulted €30,211/patient with Dyevert and €33,895/patient with current standard clinical practice. CONCLUSIONS The use of Dyevert™ Power XT resulted dominant option, due to its higher effectiveness and lower cost as compared to standard clinical practice and, therefore, a preferred option in patients with CKD stages 3b-4 undergoing PCI in Spain.

Abstract
BACKGROUND Transarterial radioembolization with yttrium-90 (Y-90 TARE) microspheres therapy has demonstrated positive clinical benefits for the treatment of liver metastases from colorectal cancer (lmCRC). This study aims to conduct a systematic review of the available economic evaluations of Y-90 TARE for lmCRC. METHODS English and Spanish publications were identified from PubMed, Embase, Cochrane, MEDES health technology assessment agencies, and scientific congress databases published up to May 2021. The inclusion criteria considered only economic evaluations; thus, other types of studies were excluded. Purchasing-power-parity exchange rates for the year 2020 ($US PPP) were applied for cost harmonisation. RESULTS From 423 records screened, seven economic evaluations (2 cost-analyses [CA] and 5 cost-utility-analyses [CUA]) were included (6 European and 1 USA). All included studies (n = 7) were evaluated from a payer and the social perspective (n = 1). Included studies evaluated patients with unresectable liver-predominant metastases of CRC, refractory to chemotherapy (n = 6), or chemotherapy-naïve (n = 1). Y-90 TARE was compared to best supportive care (BSC) (n = 4), an association of folinic acid, fluorouracil and oxaliplatin (FOLFOX) (n = 1), and hepatic artery infusion (HAI) (n = 2). Y-90 TARE increased life-years gained (LYG) versus BSC (1.12 and 1.35 LYG) and versus HAI (0.37 LYG). Y-90 TARE increased the quality-adjusted-life-year (QALY) versus BSC (0.81 and 0.83 QALY) and versus HAI (0.35 QALY). When considering a lifetime horizon, Y-90 TARE reported incremental cost compared to BSC (range 19,225 to 25,320 $US PPP) and versus HAI (14,307 $US PPP). Y-90 TARE reported incremental cost-utility ratios (ICURs) between 23,875 $US PPP/QALY to 31,185 $US PPP/QALY. The probability of Y-90 TARE being cost-effective at £ 30,000/QALY threshold was between 56% and 57%. CONCLUSIONS Our review highlights that Y-90 TARE could be a cost-effective therapy either as a monotherapy or when combined with systemic therapy for treating ImCRC. However, despite the current clinical evidence on Y-90 TARE in the treatment of ImCRC, the global economic evaluation reported for Y-90 TARE in ImCRC is limited (n = 7), therefore, we recommend future economic evaluations on Y-90 TARE versus alternative options in treating ImCRC from the societal perspective.

Abstract
INTRODUCTION A subcutaneous (SC) formulation of natalizumab has been recently authorised for multiple sclerosis patients. This study aimed to assess the implications of the new SC formulation, and to compare the annual treatment costs of SC versus intravenous (IV) natalizumab therapy from both the Spanish healthcare system (direct health cost) and the patient (indirect cost) perspectives. METHODS A patient care pathway map and a cost-minimisation analysis were developed to estimate SC and IV natalizumab annual costs over a 2-year time horizon. Considering the patient care pathway and according to natalizumab experience (IV) or estimation (SC), a national expert panel involving neurologists, pharmacists, and nurses provided information/data regarding resource consumption for drug and patient preparation, administration, and documentation. One hour of observation was applied to the first six (SC) or 12 (IV) doses, and 5 min for successive doses. The Day hospital (infusion suite) facilities at a reference hospital were considered for IV administrations and the first six SC injections. For successive SC injections, either a reference hospital or regional hospital in a consulting room was considered. Productivity time associated with travel (56 min to reference hospital, 24 min to regional hospital) and waiting time pre- and post-treatment (SC 15 min, IV 25 min) were assessed for patients and caregivers (accompanying 20% of SC and 35% of IV administrations). National salaries for healthcare professionals were used for cost estimation (€, year 2021). RESULTS At years 1 and 2, total time and cost savings (excluding drug acquisition cost) per patient, driven by saving on administration and patient and caregiver productivity for SC at a reference hospital versus IV at a reference hospital, were 116 h (a reduction of 54.6%) and €3682.82 (a reduction of 66.2%). In the case of natalizumab SC at a regional hospital, the total time and cost saving were 129 h (a reduction of 60.6%) and €3883.47 (a reduction of 69.8%). CONCLUSIONS Besides the potential benefits of convenient administration and improving work-life balance, as suggested by the expert panel, natalizumab SC was associated with cost savings for the healthcare system by avoiding drug preparation, reducing administration time, and freeing up infusion suite capacity. Additional cost savings could be derived with regional hospital administration of natalizumab SC by reducing productivity loss.

Abstract
OBJECTIVE To assess the cost-effectiveness of benralizumab (benra) vs. mepolizumab (mepo) and dupilumab (dupi) for the treatment of patients with severe uncontrolled asthma from the Spanish Health System perspective. METHODS Exacerbations avoided, quality-adjusted life years (QALYs) gained and costs in a 5-year period were estimated with a Markov model for a cohort of 1,000 patients in which, based on published evidence, 31% of the patients received biologics + oral corticosteroids (OCS) and 69% received only biologics. Efficacy data (exacerbation reduction and OCS elimination) were derived from a matching-adjusted indirect comparison. Published EQ-5D utilities per health state (biologic alone, biologic + OCS, standard of care + OCS, exacerbations, and post-exacerbations) were used for QALY estimation. Utility decrements associated with exacerbation management [-0.1 (OCS or emergency visits), -0.2 (hospitalization)] derived from the literature were applied. Costs (€, 2022) included drug acquisition (ex-factory price), administration and disease management. An expert panel (2 pneumologists and 1 pharmacist) validated all inputs. RESULTS Benra was more effective (52.21 QALYs) than mepo (51.39 QALYs) and dupi (51.30 QALYs). Benra avoided more exacerbations (2.87 exacerbations) compared to mepo (4.70 exacerbations) and dupi (5.11 exacerbations) for the 5-year horizon. Total costs/patient were €56,093.77 (benra), €59,280.45 (mepo) and €62,991.76 (dupi), resulting in benra dominating (more QALYs with lower costs) vs. mepo and dupi. CONCLUSIONS Benralizumab can be considered as a dominant treatment alternative vs. other biologic drugs for the treatment of uncontrolled severe eosinophilic asthma patients in Spain.

Abstract
INTRODUCTION AND OBJECTIVE Penile prosthesis (PP) implantation is an effective option for erectile dysfunction. Although initially PP surgery was carried out in an inpatient setting, there is a growing trend to implant PP as a major ambulatory surgery (MAS). This study aimed to perform a systematic review of the literature to identify available evidence of the implantation of PP under MAS setting and go carry out a comparison between MAS and inpatient procedures. MATERIAL AND METHODS PubMed, EMBASE, Cochrane Library and MEDES electronic databases and non-indexed supplements for scientific congresses were searched to identify articles related to the surgical implantation of PP in MAS up to February 2021. Key search terms included penile prosthesis, erectile dysfunction, ambulatory surgery, ambulatory care, and surgery. RESULTS Among 171 publications retrieved (51 PubMed, 73 EMBASE, 3 Cochrane, 2 using MEDES and 42 manual searching), 5 studies were finally selected. There were no significant differences between MAS or inpatient setting in terms of the type of device, surgical approach, or location of reservoir. Complication rates observed in both groups were similar. Implantation of PP in MAS was less expensive than inpatient surgery and was associated with acceptable patient satisfaction rates and adequate pain control. CONCLUSIONS Studies demonstrated that outpatient PP surgery can achieve similar outcomes in terms of safety and satisfaction to implantation of PP in the inpatient setting, while it could reduce costs and improve the efficiency. This research could support decision makers to extend PP surgery into the ambulatory setting.

Abstract
Background Transarterial radioembolization (TARE) with yttrium-90 microspheres is a clinically effective therapy for hepatocellular carcinoma (HCC) treatment. This study aimed to perform a systematic review of the available economic evaluations of TARE for the treatment of HCC. Methods The Preferred Reported Items for Systematic reviews and Meta-Analyses guidelines was followed by applying a search strategy across six databases. All studies identified as economic evaluations with TARE for HCC treatment in English or Spanish language were considered. Costs were adjusted using the 2020 US dollars based on purchasing-power-parity ($US PPP). Results Among 423 records screened, 20 studies (6 cost-analyses, 3 budget-impact-analyses, 2 cost-effectiveness-analyses, 8 cost-utility-analyses, and 1 cost-minimization analysis) met the pre-defined criteria for inclusion. Thirteen studies were published from the European perspective, six from the United States, and one from the Canadian perspectives. The assessed populations included early- (n = 4), and intermediate-advanced-stages patients (n = 15). Included studies were evaluated from a payer perspective (n = 20) and included both payer and social perspective (n = 2). TARE was compared with transarterial chemoembolization (TACE) in nine studies or sorafenib (n = 11). The life-years gained (LYG) differed by comparator: TARE versus TACE (range: 1.3 to 3.1), and TARE versus sorafenib (range: 1.1 to 2.53). Of the 20 studies, TARE was associated with lower treatment costs in ten studies. The cost of TARE treatment varied widely according to Barcelona Clinic Liver Cancer (BCLC) staging system and ranged from 1311 $US PPP/month (BCLC-A) to 71,890 $US PPP/5-years time horizon (BCLC-C). The incremental cost-utility ratio for TARE versus TACE resulted in a 17,397 $US PPP/Quality-adjusted-Life-Years (QALY), and for TARE versus sorafenib ranged from dominant (more effectiveness and lower cost) to 3363 $US PPP/QALY. Conclusions Economic evaluations of TARE for HCC treatment are heterogeneous. Overall, TARE is a cost-effective short- and long-term therapy for the treatment of intermediate-advanced HCC.

Abstract
Background HPV cervical cancer screening (CCS) must use validated HPV tests based on the molecular detection of either viral mRNA (Aptima HPV Assay—AHPV) or DNA. AHPV has demonstrated the same cross-sectional and longitudinal sensitivity for the detection of HSIL/CIN2+ lesions but with greater specificity than HPV-DNA tests. The study aimed to estimate the total costs of a CCS with a primary HPV test based on the detection of mRNA compared to DNA in women aged 35–65 years for the National Health System. Methods A decision-tree-based model to estimate the cost of the CCS until the first colposcopy was designed based on Spanish CCS guidelines. The total cost (€, 2019) for CCS with AHPV or DNA tests (HC2 and Cobas) was calculated, including HPV test, liquid-based cytology (LBC) and colposcopy, for a population of 7,263,529 women aged 35–65 years (assuming 70% coverage). Clinical inputs derived from a literature review were validated by a multidisciplinary expert panel. Data from head-to-head studies between different HPV tests were selected. Results The use of AHPV showed reduction of 290,541 (− 35%) and 355,913 (− 40%) LBC compared to HC2 or Cobas, respectively. Furthermore, AHPV avoided 151,699 (− 47%) colposcopies versus HC2 and 151,165 (− 47%) versus Cobas. The total cost of CCS was € 282,747,877 with AHPV, € 322,587,588 with HC2 and € 324,614,490 with Cobas. Therefore, AHPV savings € − 39,839,711 versus HC2 and € − 41,866,613 versus Cobas. Conclusions Assuming that 70% of women from 35 to 65 years attend the CCS programme, the cost of screening up to the first colposcopy using AHPV would provide cost savings of up to € 41.9 million versus DNA tests in Spain.

Abstract
BACKGROUND The DRCR.net Protocol T clinical trial assessed the comparative efficacy and safety of anti-VEGF treatments including aflibercept, ranibizumab and bevacizumab in diabetic macular edema (DME). Post -hoc analyses showed that after a 12-week induction period, there was still DME resolution in an increasing number of patients through week 24. PURPOSE To assess clinical and cost consequences of extending the anti-VEGF loading dose from 3 to 6 monthly injections in patients with persistent DME in Spain. METHODS From a hospital pharmacy perspective, a cost-consequence analysis model was developed to estimate the incremental cost needed to obtain an additional response at month 6. To estimate drug treatment costs, ex-factory prices (€, 2019) were considered for aflibercept, ranibizumab and bevacizumab. Response/nonresponse rates at 3/6 months were obtained from the Protocol T 24-week post hoc analysis (n = 546). Persistent DME was present in 50.8 and 31.6% of the 190 aflibercept-treated patients at month 3 and month 6, respectively. Of the 176 ranibizumab- and 180 bevacizumab-treated patients, 53.2 and 72.9%, respectively, had persistent DME at month 3, and 41.5 and 65.6%, respectively, had persistent DME at month 6. Sensitivity analysis considered the split of bevacizumab vials. RESULTS Extending the loading dose in nonresponder patients would cost €214,862.57, €208,488.98 and €134,483.16 to obtain 37, 21 and 13 additional aflibercept, ranibizumab and bevacizumab responder patients, respectively. The total number of extended injections (months 3-6) used in patients with persistent DME at month 6 was 180, 219 and 354 for aflibercept, ranibizumab and bevacizumab, respectively. CONCLUSIONS To extend the anti-VEGF loading dose from 3 to 6 injections necessitates investing €5882.77 (8 injections), €10,091.03 (14 injections) and €10,198.59 (30 injections) per additional responder patient (3-month nonresponders and 6-month responders) to aflibercept, ranibizumab and bevacizumab, respectively. For the total of patients treated, on average €7927.02 (14 injections) per additional responder patient would be needed.

Abstract
OBJECTIVES Herpes zoster (HZ) is an important cause of morbidity around the world, especially among the adult population aged >50 years. STUDY DESIGN A systematic review of the literature (up to October 31, 2016) was performed to identify available evidence on incidence of HZ in the general population and in a specific subpopulation in Spain. METHODS PubMed and Embase databases were searched, combining the following search terms: 'herpes zoster', 'diabetes mellitus (DM)', 'chronic obstructive pulmonary disease (COPD)', 'chronic heart failure', 'mental disorders' and 'immunocompromised'. Supplements for local scientific congresses, non-indexed Spanish journals and official epidemiological reports, potentially HZ related, were also manually searched. The inclusion criteria were the following: English or Spanish publications reporting incidence of HZ in the Spanish general population and/or specific subpopulations. No restrictions were applied on the study design or population age. RESULTS Among 269 references retrieved (48 PubMed, 148 Embase and 73 manual searching), 34 were finally included. Incidence of HZ in the general population ranged from 2.1 to 5.5/1000 person-years. HZ incidence ranged from 9.4 to 15.3/1000 patients with DM and from 11.0 to 11.4/1000 population with COPD or cardiovascular disease. In asthmatic patients, 6.9 HZ cases/1000 subjects were reported. The highest HZ incidence (1.3-400.0/1000 person-years) was in immunocompromised persons (10.0/1000 patients with cancer, 12.5/1000 patients with AIDS, from 5.0 to 240.0/1000 transplanted patients and from 6.6 to 27.0/1000 population with rheumatic diseases). Three studies estimated an increased risk of HZ in comparison with general population, for patients with DM (24%), COPD (39%) and COPD receiving inhaled corticosteroids (61%). CONCLUSIONS The results suggest a high risk of HZ in certain age groups and specific subpopulations. This study could contribute to identify target age populations and at-risk groups if implementation of HZ vaccination programmes in Spain would be considered.

Abstract
Background This study aimed at estimating the efficiency of palivizumab in the prevention of Respiratory Syncytial Virus (RSV) infection and its sequelae in preterm infants (32day 1-35day 0weeks of gestational age –wGA-) in Spain. Methods A decision-tree model was developed to compare health benefits (Quality Adjusted Life Years-QALYs) and costs of palivizumab versus a non-prophylaxis strategy over 6 years. A hypothetical cohort of 1,000 preterm infants, 32day 1-35day 0 wGA (4.356 kg average weight) at the beginning of the prophylaxis (15 mg/kg of palivizumab; 3.88 average number of injections per RSV season) was analysed. The model considered the most recent evidence from Spanish observational and epidemiological studies on RSV infection: the FLIP II study provided hospital admission and Intensive Care Unit (ICU) admission rates; in-hospital mortality rate was drawn from an epidemiological study from 2004 to 2012; recurrent wheezing rates associated to RSV infection from SPRING study were adjusted by the evidence on the palivizumab effect from clinical trials. Quality of life baseline value, number of hospitalized infants and the presence of recurrent wheezing over time were granted to estimate QALYs. National Health Service and societal perspective (included also recurrent wheezing indirect cost) were analysed. Total costs (€, 2016) included pharmaceutical and administration costs, hospitalization costs and recurrent wheezing management annual costs. A discount rate of 3.0% was applied annually for both costs and health outcomes. Results Over 6 years, the base case analysis showed that palivizumab was associated to an increase of 0.0731 QALYs compared to non-prophylaxis. Total costs were estimated in €2,110.71 (palivizumab) and €671.68 (non-prophylaxis) from the National Health System (NHS) perspective, resulting in an incremental cost utility ratio (ICUR) of €19,697.69/QALYs gained (prophylaxis vs non-prophylaxis). Results derived from the risk-factors population subgroups analysed were in line with the total population results. From the societal perspective, the incremental cost associated to palivizumab decreased to an €1,253.14 (ICUR = €17,153.16€/QALYs gained for palivizumab vs non-prophylaxis). One-way and probabilistic sensitivity analyses confirmed the robustness of the model. Conclusions The prophylaxis with palivizumab is efficient for preventing from RSV infections in preterm infants 32day 1-35day 0 wGA in Spain.

Abstract
To evaluate the cost-effectiveness of ledipasvir/sofosbuvir (LDV/SOF) in treatment-naïve patients with chronic hepatitis C (CHC) genotype 1 (GT1) in the absence or mild fibrosis (F0-F1) versus advanced fibrosis (F2-F4), from the perspective of the Spanish Health System. A Markov model was developed to simulate disease progression, estimating costs and outcomes [life years gained (LYG) and quality-adjusted life years (QALY)] derived from starting with LDV/SOF in patients with F0-F1 compared with F2-F4. Therapy duration was 8 weeks in noncirrhotic patients with viral load <6 million IU/mL and 12 weeks in the remaining patients. Sustained virologic response rates were obtained from real-world cohort studies. Transition probabilities, utilities and direct costs were obtained from the literature. A 3% annual discount rate was applied to costs and outcomes. Sensitivity analyses were performed. LDV/SOF in F0-F1 patients was a dominant strategy, being more effective (19.85 LYG and 19.80 QALY) than beginning treatment in F2-F4 patients (18.63 LYG and 16.25 QALY), generating savings of €9228 per patient (€3661 due to disease management and monitoring). In a cohort of 1000 patients, LDV/SOF in F0-F1 patients decreased the number of cases of decompensated cirrhosis (93%), hepatocellular carcinoma (97%) and liver-related deaths (95%) and prevented 6 liver transplants compared to initiating LDV/SOF in F2-F4 patients. In CHC treatment-naïve GT1 patients, starting treatment with LDV/SOF in patients with F0-F1 compared to those with F2-F4 increases effectiveness by 1.22 LYG and 3.55 QALY gained and reduces disease burden and it is associated with cost savings.

Abstract
OBJECTIVE To assess the cost-effectiveness of celecoxib and non-selective non-steroidal anti-inflammatory drugs for the treatment of osteoarthritis in clinical practice in Spain. METHODS A decision-tree model using distribution, doses, treatment duration and incidence of GI and CV events observed in the pragmatic PROBE-designed «GI-Reasons» trial was used for cost-effectiveness. Effectiveness was expressed in terms of event averted and quality-adjusted life-years (QALY) gained. QALY were calculated based on utility decrement in case of any adverse events reported in GI-Reasons trial. The National Health System perspective in Spain was applied; cost calculations included current prices of drugs plus cost of adverse events occurred. The analysis was expressed as an incremental cost-effectiveness ratio per QALY gained and per event averted. One-way and probabilistic analyses were performed. RESULTS Compared with non-selective non-steroidal anti-inflammatory drugs, at current prices, celecoxib treatment had higher overall treatment costs €201 and €157, respectively. However, celecoxib was associated with a slight increase in QALY gain and significantly lower incidence of gastrointestinal events (p<.001), with mean incremental cost-effectiveness ratio of €13,286 per QALY gained and €4,471 per event averted. Sensitivity analyses were robust, and confirmed the results of the base case. CONCLUSION Celecoxib at current price may be considered as a cost-effective alternative vs. non-selective non-steroidal anti-inflammatory drugs in the treatment of osteoarthritis in daily practice in the Spanish NHS.

Abstract
OBJECTIVE To compare the cost of treating rheumatoid arthritis patients that have failed an initial treatment with methotrexate, with subcutaneous abatacept versus other first-line biologic disease-modifying antirheumatic drugs. METHOD Subcutaneous abatacept was considered comparable to intravenous abatacept, adalimumab, certolizumab pegol, etanercept, golimumab, infliximab and tocilizumab, based on indirect comparison using mixed treatment analysis. A cost-minimization analysis was therefore considered appropriate. The Spanish Health System perspective and a 3 year time horizon were selected. Pharmaceutical and administration costs (Euros 2013) of all available first-line biological disease-modifying antirheumatic drugs were considered. Administration costs were obtained from a local costs database. Patients were considered to have a weight of 70 kg. A 3% annual discount rate was applied. Deterministic and probabilistic sensitivity analyses were performed. RESULTS Subcutaneous abatacept proved in the base case to be less costly than all other biologic antirrheumatic drugs (ranging from Euros -831.42 to Euros -9,741.69 versus infliximab and tocilizumab, respectively). Subcutaneous abatacept was associated with a cost of Euros 10,760.41 per patient during the first year of treatment and Euros 10,261.29 in subsequent years. The total 3-year cost of subcutaneous abatacept was Euros 29,953.89 per patient. Sensitivity analyses proved the model to be robust. Subcutaneous abatacept remained cost-saving in 100% of probabilistic sensitivity analysis simulations versus adalimumab, certolizumab, etanercept and golimumab, in more than 99.6% versus intravenous abatacept and tocilizumab and in 62.3% versus infliximab. CONCLUSIONS Treatment with subcutaneous abatacept is cost-saving versus intravenous abatacept, adalimumab, certolizumab, etanercept, golimumab, infliximab and tocilizumab in the management of rheumatoid arthritis patients initiating treatment with biological antirheumatic drugs.

Abstract
OBJECTIVES To estimate the incremental cost per life-year gained (LYG) of aflibercept in combination with FOLFIRI as second-line treatment in metastatic colorectal cancer (mCRC) patients previously treated with oxaliplatin. METHODS Based on clinical trial VELOUR results, a three-state Markov model (stable disease, progression and death) with 2-week cycle duration was designed. Transition to health state «progression» implied the interruption of second-line treatment and administration of a third-line treatment (post-second line chemotherapy). Cost estimation included disease management cost (pharmaceutical, adverse event management, administration costs, etc.). Both cost and outcomes were discounted (3% annually). Sensitivity analyses (SA) were performed to test model robustness. RESULTS Administration of aflibercept + FOLFIRI as second-line treatment provided 1.78 LYG (21 life-months gained). With FOLFIRI 1.43 LYG (17 months) were obtained. The cost of the clinical management of aflibercept + FOLFIRI implied an additional investment of Euros 13,564 compared with FOLFIRI for a lifetime horizon, being total costs for aflibercept + FOLFIRI of Euros 38,346, compared to Euros 24,782 with FOLFIRI. In the cost-effectiveness analysis Euros 38,931/LYG was obtained with aflibercept in combination with FOLFIRI versus FOLFIRI. CONCLUSION Aflibercept in combination with FOLFIRI increased overall survival versus FOLFIRI, so it is an effective strategy in the treatment of patients with mCRC. Aflibercept in combination with FOLFIRI is an efficient strategy for second-line mCRC treatment from the National Health System perspective.

Abstract
OBJECTIVE To estimate treatment costs of blepharospasm, cervical dystonia(CD), upper limb spasticity (ULS) and spasticity in children with cerebral palsy (SCCP) with botulinum neurotoxin type A (BoNT-A) in Spain. METHOD Annual BoNT-A treatment costs were calculated (2013 ex-factory price () applying RDL 8/2010 and RDL 9/2011 deductions), based on initial dose (id), average dose (ad) and maximum dose (md) according to Summary of Product Characteristics of Botox® (100U/50U), Dysport®(500U) and Xeomin® (100U) and considering the use of complete vials.In addition, annual treatment costs were calculated considering the useof vials in more than one patient and also patient population annual treatment costs based on diseases' prevalence. RESULTS Annual BoNT-A treatment costs per patient were estimated at between 265 and 2,120 with savings from 10% to 55% accordingto the selected BoNT-A. CD and ULS treatment provided the greatest cost per patient. Botox® provided greater savings in ULS (id/ad), CD(id), and in blepharospasm and SCCP (id/ad/md). Dysport® treatment was less costly in CD (md) and ULS (md), while Xeomin® was in CD(ad). Based on the estimated treated population in Spain, the annual treatment costs ranged from 368,392 to 13,958,836 depending on indication, dose and BoNT-A considered. CONCLUSIONS The appropriate BoNT-A choice would lead to considerable savings for the National Health System. Botox® would generate lower costs per patient than other BoNT-A products in 9 out of 12 scenarios considered.

Abstract
OBJECTIVE To provide estimates of the efficiency for chemotherapy strategies used in Spain. METHODS Published reports of the phase-III clinical trials for chemotherapies used for the most prevalent solid tumours in Spain were retrieved. The incremental cost-effectiveness ratio (ICER) was calculated for each strategy compared to the control group in the clinical trial, with the National Health System perspective. The total cost (?, 2012) including only drug cost (exfactory price) was estimated based on the total units of each drug required for administration (no vial wastage), with the dosification and number of cycles specified in the publication for each treatment arm. Effectiveness was measured as month of overall survival (OS) and/or month of progression free survival (PFS). RESULTS A total of 40 chemotherapies for 13 different advanced or metastatic tumours were assessed. OS ranged from 5.3 to 33.3 months for the 34 therapies that included the information with hazard ratios (HR) values from 0.49 to 1.15 when compared with its control group. PFS ranged, from 39 therapies with these data, between 1.5 to 12.4 months, with HR from 0.33 to 1.52. ICERs were between ?2,142.57 and ?60,996.37 per each OS month gained, and from ?2,102.54 to ?661,845.27 per PFS month gained. CONCLUSION The variety and heterogenicity of survival and ICERs results, suggest disparity of criteria in the price and reimbursement process of drugs in Spain. The continuous advances in oncology seem to require economic revaluations of drugs.

Abstract
The aim of this study is to provide estimates on the incidence of rotavirus infection requiring hospitalization in children <or=5 years of age during the 1999-2000 period in Spain and the associated direct cost of these hospitalizations. Hospital admissions attributable to rotavirus were estimated by using data on confirmed laboratory reports of rotavirus and hospital admissions due to acute gastroenteritis. During the study period a total of 32541 cases of pathogens responsible for acute gastroenteritis were reported to the microbiological information national system (SIM) and 14.0% were rotavirus. The proportion of laboratory-confirmed rotavirus cases was extrapolated to the total number of hospitalizations for acute gastroenteritis in children <or=5 years of age. An annual incidence of 1.0 hospital admissions attributable to rotavirus per 1000 persons <or=5 years of age was found, although during the winter season it reached 2.5 hospitalizations per 1000. Overall, the estimated annual number of days of hospitalization attributable to rotavirus was 8742 days that results in a cost of 3.6 million per year.

Abstract
BACKGROUND Streptococcus pneumoniae is a significant cause of meningitis and septicemia in early infancy, being associated to a high case-fatality rates and serious sequelae. OBJECTIVE To investigate the burden of invasive disease caused by S. pneumoniae in Valencia, Spain, during a three-year period (1996-1998). METHODS Hospital-based prospective active surveillance program for invasive bacterial diseases in children < or = 15 years of age in Valencia, from December 1, 1995 to January 1999. RESULTS A total of 94 cases of invasive pneumococcal disease were detected in patients < or = 15 years of age. The overall annual incidence of invasive pneumococcal disease was 4.6/100,000 persons, < or = 15 years of age. The incidence of invasive disease and meningitis was higher among children younger than 2 years of age (16.8 and 3.8, respectively). Serotypes 19, 14 and 6 accounted for 83% of the isolates. CONCLUSIONS The age distribution of invasive pneumococcal disease and meningitis shows a peak in the first two years of life and a decline thereafter. Serotypes 19, 14 and 6 are those primarily responsible for invasive pneumococcal disease in children of this region of Spain.

Abstract
In order to assess the effectiveness of sildenafil under routine conditions of use in primary care settings and to evaluate its impact on patient's life satisfaction and partner's satisfaction with treatment for erectile dysfunction (ED), an open, multicentre, observational, prospective study was designed in which 2816 patients were treated with sildenafil for at least 10 weeks. Effectiveness was assessed using the International Index of Erectile Dysfunction (IIEF), life satisfaction was measured with 'Life-satisfaction Check List' (LISAT 8), and EDITS was optionally used to assess the partner's satisfaction with ED therapy. Sildenafil was effective in 86.6% of patients. All dimensions of IIEF significantly increased with sildenafil, particularly erectile domain which overall sample mean score improved was 13.2 points (P < 0.001). The greatest increases in satisfaction with all aspects of life were seen in sex life and relationship with partner dimensions. The patients' partners, answered by a minority of partners, were highly satisfied with the treatment and its rapid action, therefore they were in favour of continuing with same. The adverse events occurring were similar to those seen in clinical research on sildenafil in the premarketing phase. No control group was included in this study.

Abstract
An approach to the burden of varicella can be obtained from information on the hospitalizations. Data were obtained from the national surveillance system for hospital data. All hospital discharges for varicella were analyzed for the 1995-1998 period. A total of 3632 primary varicella-related discharges were identified, representing an annual incidence of 2.8 per 100,000 population. A total of 58% of cases were <10 years of age and 33% were 21-50 years old. Each year primary varicella will be responsible for 6174 days of hospitalization, representing an annual cost of 1.6 million euros. There is substantial severe morbidity each year from varicella that, to reduce, would require vaccination of infants and susceptible adults.

Abstract
This epidemiological survey was undertaken to estimate the annual burden of hospitalizations for pertussis in Spain during a four-year period 1995-1998. Data were obtained from the national surveillance system for hospital data. All hospital discharges for pertussis (ICD-9- CM 033) were analyzed. The annual incidence of hospitalization for pertussis was 1.7 per 100,000 population. Eighty-nine percent of the cases were < 1 year of age (incidence of 78 per 100,000) and 95% were < or =5 years of age (incidence of 28 per 100,000). During the study period, 14 deaths were reported among patients hospitalized by pertussis. Despite of the high immunization rates, many pertussis cases occur each year, mostly of them among very young children.
