Abstract
Introduction: Multiple Sclerosis (MS) is a chronic neurodegenerative and inflammatory disease that affects the Central Nervous System. Despite significant therapeutic
advances in recent decades, the population with MS exhibits higher hospitalization rates compared to the general population, resulting in a relevant socioeconomic impact.
Objectives: This study aims to evaluate the use of Key Performance Indicators (KPI) in
patients with MS, aiming at improvements in the care and clinical management of this
population. Materials and methods: This is an observational, retrospective study with an
epidemiological and clinical aspects. The variables analyzed included age, gender, ethnicity, disease duration, occurrence of relapses within one year, Expanded Disability Status
Scale (EDSS) scores, treatments, and presence of comorbidities. As for the KPI, the
number of hospitalizations and admitted patients (measuring production), average length
of stay (measuring efficiency), as well as readmission and mortality rates (measuring the
quality of medical care) were evaluated. Results: A total of 332 hospitalizations in 153
patients were analyzed, resulting in an average of 2.16 hospitalizations per patient, with
a maximum value of 18 and a minimum of 1. The majority of hospitalizations occurred in
women (75%). The mean age was 36 ± 7.8 years, with 26.5% of the patients aged between 18 and 39 years. The majority of patients were female (75%) and self-declared as
white (94.8%). The hospital mortality rate was 2.4%, and the average length of stay was
6.5 days. The main reason for hospitalization was related to disease exacerbation, with
the majority of patients admitted for pulse therapy. Most patients had comorbidities associate with MS. Conclusion: The high number of hospitalizations in this population was
confirmed, with the majority of cases having an EDSS score below 3.5. Hospitalizations
of patients with MS can be reassessed in order to increase the quality of life for these
cases, considering the performance of ambulatory procedures for treating relapses.
