RESUMO
Background: The use of smart pump technology has shown to be profitable in the intensive care unit (ICU) because it avoids costs from prevented medication errors and allows for savings on disposables and medications by establishing standardized concentrations and dosing units. Objective: The objective of the study is to evaluate the economic impact of the implementation of smart infusion pumps in the consumption of intravenous (IV) solutions in an ICU. Methods: A retrospective observational study was conducted with a pre-post design. The study occurred in the adult ICU of the Hospital Juárez de México. The pattern of consumption of IV solutions (sodium chloride 9%, Hartmann's solution, dextrose 5% and 10%, sodium chloride 0.9% with dextrose 5%) was analyzed preimplementation and postimplementation of 50 Plum A+™ pumps with Hospira MedNet™ security software. Using the TreeAge Pro 2016 software, deterministic and probabilistic analyses were carried out (10 000 Monte Carlo simulations) to confirm the robustness of the annual consumption comparison and the associated expenses before and after implementing smart technology. Results: The implementation of the smart pumps reduced the annual consumption of IV solutions to 8994 units (18%) and 3649 liters (22.3%). In the first year, MXN$55 850.97 were saved. From an institutional perspective and with a probability of 0.63, the use of MedNet™ technology proved to be a lower cost alternative (17.1% saved) with respect to the conventional infusion systems. Conclusion: The implementation of smart infusion pumps allows savings, specifically for the IV solutions used in ICU.
RESUMO
Limited data exist on the costs of care of patients with multiple sclerosis (MS) in low- to middle-income nations. The purpose of this study was to describe the economic burden associated with care of Mexican patients with relapsing-remitting MS in a representative sample of the largest institution of the Mexican public healthcare system. We analysed individual data of 492 patients (67% women) with relapsing-remitting MS registered from January 2009 to February 2011 at the Mexican Social Security Institute. Direct costs were measured about the use of diagnostic tests, disease-modifying therapies (DMTs), symptoms control, medical consultations, relapses, intensive care and rehabilitation. Four groups were defined according to DMT alternatives: (1) interferon beta (IFNß)-1a, 6 million units (MU); (2) IFNß-1a, 12MU; (3) IFNß-1b, 8MU; and (4) glatiramer acetate. All patients received DMTs for at least 1 year. The most frequently used DMT was glatiramer acetate (45.5%), followed by IFNß-1a 12MU (22.6%), IFNß-1b 8MU (20.7%), and IFNß-1a 6MU (11.2%). The mean cost of a specialised medical consultation was 74.90 (US $107.00). A single relapse had a mean total cost of 2,505.97 (US $3,579.96). No differences were found in annualised relapse rates and costs of relapses according to DMT. However, a significant difference was observed in total annual costs according to treatment groups (glatiramer acetate being the most expensive), mainly due to differences in unitary costs of alternatives. From the public institutional perspective, when equipotent DMTs are used in patients with comparable characteristics, the costs of DMTs largely determine the total expenses associated with care of patients with relapsing-remitting MS in a middle-income country.
