RESUMO
INTRODUCTION AND OBJECTIVES: The aim of this analysis was to evaluate the burden and cost of complications due to poor anticoagulation control in patients with nonvalvular atrial fibrillation (NVAF) treated with vitamin K antagonists (VKA) in Spain. METHODS: An analytical model was used to estimate annual differences in ischemic stroke, major bleeding, deaths, costs, and potential years of life lost between patients with poor anticoagulation control (time in therapeutic range <65%) and adequate control (time in therapeutic range ≥ 65%) with a 1-year time horizon. Information on the target population (patients ≥ 65 years), event rates, and costs were obtained from national sources. Direct costs in euros (2018) were included from the perspective of the national health system (NHS) and direct and indirect costs from the societal perspective. A sensitivity analysis was performed with post-hoc data from the SPORTIF III/V trials. RESULTS: We analyzed a hypothetical cohort of 594 855 patients, 48.3% with poor anticoagulation control, with an increase of 2321 ischemic strokes, 2236 major bleeding events and 14 463 deaths, and an annual incremental cost between 29 578 306 from the NHS perspective and 75 737 451 from the societal perspective. The annual impact of mortality was 170 502 potential years of life lost. The results of the sensitivity analysis showed that the annual cost would reach 97 787 873 from the societal perspective. CONCLUSIONS: Poor anticoagulation control with AVK has a strong impact on loss of health and on increased spending for the NHS.

INTRODUCTION: Etanercept (ETN), a highly effective biological agent for the treatment of psoriasis (PSO) and psoriatic arthritis (PsA), is widely used in Spain. However, evidence of its economic impact is limited, indicating the need for a systematic review of the economic assessments conducted on the use of ETN in the treatment of both PSO and PsA in Spain. METHODS: A systematic review was carried out in PubMed, Embase, Cochrane Library, Health Technology Assessment reports and not indexed sources up to November 2018. The inclusion criteria were economic evaluations (total and partial) and dose optimization studies published in English or Spanish on the use of ETN to treat PSO and PsA for ETN in Spain. RESULTS: A total of 402 publications were identified, of which 32 were selected for inclusion in the review; of these 32 publications, 81.3% analyzed PSO (14 full economic evaluations, 5 partial economic evaluations and 7 dose optimization studies) and 18.8% analyzed PsA (1 economic analysis and 5 dose optimization studies). The perspective of the Spanish National Health Service (NHS) was used in 90.0% (n = 18) of the full and partial economic evaluations. The time horizons ranged from 12 weeks to 2 years. Reductions in the Psoriasis Area and Severity Index (PASI) of 50, 75 and 90% (PASI 50, 75 and 90, respectively) were most commonly used as efficacy outcomes in the complete evaluations. The economic impact of ETN ranged from 9110-14,337/PASI 75 at 12 weeks (50 mg/week) to 82,279/PASI 90 at 2 years, depending on the health outcome, time horizon and ETN dose used. Only one study determined the cost of using ETN for the treatment of PSO (29,430-52,367/QALY for dose 2 × 25 mg/week or 50 mg/week, respectively). Only one partial economic evaluation on PSA was identified (NHS perspective), resulting in an ETN annual cost of 8585/patient-year. CONCLUSION: Consistent evidence on the economic impact of ETN for the treatment of PSO and PSA in Spain is lacking, mainly due to the highly heterogeneous methodology used and the broad range of outcomes found in the economic evaluations published to date.

RESUMO
BACKGROUND: Inadequate preoperative patient preparation causes organizational, economic, and emotional problems to patients and professionals. In Spain, no current evidence is available on either the rate of compliance or the impact of good compliance with preoperative recommendations by patients in the ambulatory setting. However, it is known that around 25% of surgical cancellations in the major ambulatory surgery (MAS) are due to poor compliance with these recommendations and, therefore, avoidable. Introducing innovative tools based on mobile health (mHealth) apps may help patients meet the preoperative recommendations and, consequently, reduce the rate of cancellations in the ambulatory setting. OBJECTIVE: The objective of this study was to evaluate the effectiveness of the Listeo+ mHealth app as a tool for improving compliance with preoperative recommendations in MAS versus standard of care (SOC). METHODS: A multicenter, randomized, open-label clinical trial that compares SOC with the additional use of Listeo+, a specific mHealth app for MAS preoperative patient monitoring, is being conducted. The study will include patients aged ≥18 years with surgical indication for MAS who meet the necessary technological and connectivity requirements. Patients in the control group will receive written preoperative recommendations, while those in the intervention group will additionally use the Listeo+ mHealth app. There will be a competitive recruitment of 790 patients during 6 months in 4 hospitals in Andalusia (Spain) that belong to the National Health System. The primary efficacy outcome is the level of compliance with preoperative recommendations. Secondary outcomes include the rate of cancellations, associated resource consumption, and perceived usability and utility with Listeo+ by participants of the intervention group. Simple randomization 1:1 procedure will be used to allocate patients to each study group. RESULTS: The technological development of Listeo+ and the integration and interoperability of information systems was completed in September 2017. Subsequently, simulation tests were performed with Listeo+, and a pilot study was initiated with real patients that concluded successfully in October 2017. Patient recruitment began in December 2017 in the 4 participating centers. After an intermediate analysis performed 10 months after the start of the recruitment phase, the data collection and cleaning phases are estimated to be completed in April 2019, and the analysis with the final results will be conducted in July 2019. CONCLUSIONS: Progress in the integration and interoperability of information systems represents a major step forward in the field of mHealth. The app will allow health professionals to monitor in real-time patients' preparation and critical preoperative recommendations fulfillment. We expect a reduction in avoidable preoperative cancellations due to a lack of or a poor patient preparation. Self-assessed Web-based questionnaires and focus group will provide important information about the perceived usability and utility of Listeo+ app among patients and health care professionals.
