Objectives: Physiotherapy in an adult intensive care unit (ICU) affects health outcome. To justify the investment in ICU physical therapy, the cost savings associated with its benefits need to be established. The main objective of this study is to evaluate the potential cost savings of implementing 24-hour, 7-days-per-week physiotherapist (24/7-PT) in a Chilean public high-complex specialized ICU., Methods: Using clinical data from a literature review and a micro-costing technique, we conducted a cost-benefit analysis in the National Institute of Thorax in Chile. Our example scenario involves 697 theoretical admissions of adult patients with cardiovascular or respiratory diseases, and the costs and benefits by reduction of length of stay in ICU, days of mechanical ventilation, and days with respiratory infections during the first year and 5 years of admissions. A sensitivity analysis was considered according to the variability in total costs, production income, and clinical benefits., Results: Net cost savings generated in our example scenario demonstrate that the implementation of 24/7-PT produces a minimum saving for the institution of $16 242 during the first year and $69 351 over a 5-year interval considering individual income production. Out of the 30 scenarios included in the sensitivity analyses, 26 (87%) demonstrated net savings., Conclusions: A financial model, based on literature review and actual cost data, projects that 24/7-PT intervention is a cost-benefit alternative in adult ICU patients with cardiovascular or respiratory diseases in Chile. It is necessary a scenario of at least 3 sessions per day with insurance payment for individual treatments to support the long-term implementation of a 24/7-PT program., (Copyright © 2020.

Background: Copper mining installations in Chile use a large number of workers who do their jobs at high altitudes, exposing them to the conditions of chronic intermittent hypobaric hypoxia. The Chilean Safety Association implements the surveillance program., Objective: This organization, under the sponsorship of the Chilean Superintendency of Social Security, was interested in determining the costs involved in this program to support its decision-making processes and to improve its performance., Methods: Direct operating costs of the Hypoxia Medical Surveillance Program were determined through on-site surveys applied to the organization's local agencies in charge. The microcosting method was used, quantifying personnel costs, consumables, and equipment and overhead costs. Time-driven activity-based costing was partially adapted for the allocation of personnel and equipment costs. Costs concerning activities, groups of activities and items, and average cost per exposed worker were determined., Results: The annual costs of the program were $127 299.58. The highest costs corresponded to the assessment activities, which were $89 192.13, representing 60.06% of the total. The labor factor costs were $77 568.50, which represents 60.93% of the total. The average cost per worker in the program is $21.17., Conclusions: The partial adaptation of the time-driven activity-based costing method in combination with the microcosting method provides a suitable solution to determine the total costs of running a healthcare program of this kind. The information generated by this study will aid in the decision-making and management processes of the Hypoxia Medical Surveillance Program., (Copyright © 2019 ISPOR--The professional society for health economics and outcomes research.

Purpose: To assess the cost-effectiveness of 3 models of exercise-based cardiac rehabilitation (CR) compared with standard care in survivors of acute coronary syndrome (ACS) within the public health system in Chile., Methods: A Markov model was designed using 5 health states: ACS survivor, second ACS, complications, general mortality, and cardiovascular mortality. The transition probabilities between health states for standard care and corresponding relative risk for CR were calculated from a systematic review. Health benefits were measured with the EuroQol 5-dimensional 3-level (EQ-5D-3L) survey. Costs for each health state were quantified using the national cost verification study. The CR cost was estimated with a microcosting methodology. The time horizon was a lifetime and the discount rate was 3% per year for costs and benefits. Deterministic and probabilistic analyses were performed. Structural uncertainty was managed by designing 3 scenarios: CR as currently delivered in a specific Chilean public health center, CR as recommended by South American guidelines, and CR as proposed for low-resource settings., Results: Cardiac rehabilitation versus standard care showed an incremental cost-effectiveness ratio for the standard model of $722, for the South American model of $1247, and for the low-resource model of $666. The tornado diagram showed higher uncertainty in relative risk for the complications state and for the second ACS state., Conclusion: Considering a cost-effectiveness threshold of 1 unit of gross domestic product per capita (∼$19 000), CR is highly cost-effective for the public health system in Chile.

This article reviews the most relevant methodological aspects involved in Health Technology Assessment (HTA). Firstly, it addresses the process of defining the research problem (or scoping). Then it explains some specific aspects of systematic reviews of evidence, as well as indirect and mixed comparisons of the effectiveness of interventions. It covers also the methods for economic evaluation in healthcare and the budget impact analysis of interventions. Finally, the paper provides an empirical insight on the methodological emphasis used by HTA agencies around the world, and reflects on the available capacities in our country in the topics discussed.
