Economic impact of improving patient safety using Sugammadex for routine reversal of neuromuscular blockade in Spain.

BACKGROUND: Neuromuscular blocking (NMB) agents are often administered to facilitate tracheal intubation and prevent patient movement during surgical procedures requiring the use of general anesthetics. Incomplete reversal of NMB, can lead to residual NMB, which can increase the risk of post-operative pulmonary complications. Sugammadex is indicated to reverse neuromuscular blockade induced by rocuronium or vecuronium in adults. The aim of this study is to estimate the clinical and economic impact of introducing sugammadex to routine reversal of neuromuscular blockade (NMB) with rocuronium in Spain. METHODS: A decision analytic model was constructed reflecting a set of procedures using rocuronium that resulted in moderate or deep NMB at the end of the procedure. Two scenarios were considered for 537,931 procedures using NMB agents in Spain in 2015: a scenario without sugammadex versus a scenario with sugammadex. Comparators included neostigmine (plus glycopyrrolate) and no reversal agent. The total costs for the healthcare system were estimated from the net of costs of reversal agents and overall cost offsets via reduction in postoperative pneumonias and atelectasis for which incidence rates were based on a Spanish real-world evidence (RWE) study. The model time horizon was assumed to be one year. Costs were expressed in 2019 euros (€) and estimated from the perspective of a healthcare system. One-way sensitivity analysis was carried out by varying each parameter included in the model within a range of +/- 50%. RESULTS: The estimated budget impact of the introduction of sugammadex to the routine reversal of neuromuscular blockade in Spanish hospitals was a net saving of €57.1 million annually. An increase in drug acquisition costs was offset by savings in post-operative pulmonary events, including 4806 post-operative pneumonias and 13,996 cases of atelectasis. The total cost of complications avoided was €70.4 million. All parameters included in the model were tested in sensitivity analysis and were favorable to the scenario with sugammadex. CONCLUSIONS: This economic analysis shows that sugammadex can potentially lead to cost savings for the reversal of rocuronium-induced moderate or profound NMB compared to no reversal and reversal with neostigmine in the Spanish health care setting. The economic model was based on data obtained from Spain and from assumptions from clinical practice and may not be valid for other countries.

Mortality of septic old and adult male mice correlates with individual differences in premorbid behavioral phenotype and acute-phase sickness behavior.

Individual differences in premorbid behaviors and in those exhibited in the course of an infection disease may be useful to explain the individual susceptibility to infections, the underlying neuroimmunological mechanisms and be helpful to design patient oriented treatments with better prediction of pharmacological reactivity/outcome. Age (old) and gender (male) are also considered vulnerability factors. In the present study, the motor, emotional, anxious-like and social phenotypes of adult (6-month-old) and old (18-month-old) male C57BL/6 × 129Sv mice were determined using both a transversal and longitudinal designs prior to the analysis of LPS (150 mg/kg, i.p.)-induced sickness behavior and mortality. The results show: i) Individual premorbid behavioral phenotype had short- and long-term predictive value of hours of survival; ii) Persistence of behavioral traits from adulthood to old age and predictive value on hours of survival; iii) First signs of sickness behavior were also predicting mortality, mostly in old animals; iv) LPS-sickness behavior was the same at both ages but adult animals were able to show attempts of motor recovery; v) The mortality rate over 96 h was 100% in both ages, but old animals showed shorter survival times. In summary, these results confirm the relevance of age/aging but also individual behavioral differences in the premorbid phenotype and the morbidity response to the LPS-induced-sepsis that correlate with the individual's mortality. Thus, this work supports the translational scenarios to study personalized evaluation of risks factors and psycho-neuro-immunological mechanisms relevant for better interventions and prognosis in the critically ill young but specially aged patient population.
