Objective: To estimate the incidence of in-hospital admissions of Parkinson´s disease (PD) in Spain during the last decade (2010-2019) and describe the epidemiology of these hospitalizations.
Background: Parkinson´s disease (PD) is the second most common neurodegenerative disease worldwide and its prevalence will double by 2030 (1). PD also increases hospital admission rates and healthcare costs (2).
Method: This is a retrospective observational study using the Spanish National Hospital Discharge Database (SNHDD) that analyses the trends of PD hospitalizations in Spain during the last decade (2010-2019). PD diagnosis was classified as a primary/secondary diagnosis in relation to hospital admission. Data such as age, sex, comorbidities (Charlson Comorbidity Index, CCI) and in-hospital mortality (IHM) were collected.
Results: The total number of hospitalizations during 2010-2019 was approximately 410000. The proportion of women was 46.88% (SD =8.77). The proportion of male sex increased progressively over time (52.29% in 2010-2011 compared to 54.12% in 2018-2019). There was also a slight increase in age (79.14 years in 2010-2011 vs. 80.05 in 2018-2019; p<0.001) and in comorbidities (mean CCI 1.55 in 2010-2011 vs. 1.79 in 2018-2019, p<0.001). The overall IHM for PD patients in Spain in the last decade was 10.48% (42,897 in-hospital deaths), showing a slight increase over time (10.4% in 2010-2011 vs 10.87% in 2018-2019, p<0.001). Most patients had PD as a secondary diagnosis (95.84%) in relation to hospitalization, with increasing trends in age, male sex, comorbidities and IHM. Among hospitalizations of PD as a primary diagnosis (4.16%), comorbidity and age remained unchanged for both sexes, but IHM also increased (2.34% in 2010-2011 vs 3.59% in 2018-2019, p=0.031). Figures 1 and 2 shows the jointpoint analysis of hospitalizations regarding sex and primary/secondary diagnosis over the study period (2010-2019).
Conclusion: PD has increased as a primary and secondary diagnosis among hospitalizations in Spain during the last decade (2010-2019). There has been an increase in mean age, male sex, comorbidities and IHM among patients hospitalized with PD.
