Comorbidity burden of patients with Parkinson's disease and Parkinsonism between 2003 and 2012: A multicentre, nationwide, retrospective study in China.

ABSTRACT: Parkinson's disease (PD) and Parkinsonism are common neurodegenerative disorders with continuously increasing prevalence, causing high global burdens. However, data concerning the comorbidity burden of patients with PD or Parkinsonism in China are lacking. To investigate the health condition and comorbidity burden, a total of 3367 PD and 823 Parkinsonism patients were included from seven tertiary hospitals in seven cities across China from 2003 to 2012. Their comorbidity burden was collected and quantified by the Elixhauser Comorbidity Index (ECI) and Charlson Comorbidity Index (CCI). The comorbidity spectra differed between PD and Parkinsonism patients. Compared with PD patients, Parkinsonism patients were older (69.8 ± 11.5 vs. 67.9 ± 11.4, P < 0.001); had a higher comorbidity burden, including ECI (1.1 ± 1.2 vs. 1.0 ± 1.2, P < 0.001) and CCI (1.3 ± 1.6 vs. 1.1 ± 1.5, P < 0.001); and had higher hospitalization expenses. The ECI (1.1 ± 1.3 vs. 0.9 ± 1.1, P < 0.001) and CCI (1.3 ± 1.6 vs. 0.9 ± 1.2, P < 0.001) were higher in males than in females. The average length of stay and daily hospitalization expenses increased with age, as did ECI and CCI. This is the first study to report the disease burden of Chinese PD and Parkinsonism patients. It provides useful information to better understand their health status, and to raise the awareness of clinicians for providing better health care.

Project description:ObjectivesHyperkalaemia is a potentially life-threatening disorder in patients undergoing haemodialysis (HD). Excess mortality and hospitalisation have been associated with hyperkalaemia (HK) after the long (2-day) interdialytic interval (LIDI) in patients on thrice a week HD compared with the short (1-day) interdialytic interval. Moreover, not much research has been conducted in China on the descriptive epidemiology and management of HK among different HD centres. The aim of this study is to address this evidence gap by investigating the risk factors associated with HK clinical burden at the HD facility level, current HD centres management patterns, serum potassium management patterns, as well as the risk factors associated with crude mortality in China.DesignMulticentre, observational, retrospective cohort study.SettingThis study plans to enrol 300 HD centres across China. Haemodialysis centres having ≥100 patients on maintenance HD within 3 years before study initiation, with participation willingness, routine blood collection post-LIDI and death records will be included.ParticipantsPatients aged ≥18 years and on chronic HD for ≥3 months will be considered eligible. Summary data about serum potassium, characteristics of patients, facility practice patterns will be collected at HD facility level and death records will be at the patient level.Primary and secondary outcome measuresThe primary outcome will be to examine the association between suspected risk factors and HK prevalence at HD facility level. Suspected risk factors include dialysis prescriptions and serum potassium testing frequency, characteristics of patients and related medication usage. The secondary outcome will be to determine the HK prevalence, serum potassium management pattern and risk factors associated with crude mortality. The primary and secondary outcomes will be analysed using regression models. Exploratory outcomes will further investigate the risk factors associated with serum potassium ≥6.0 and ≥6.5 mmol/L.ConclusionThe study is expected to provide insights to improve dialysis practice patterns and understand the clinical burden of HK.Ethics and disseminationThis study protocol was reviewed and approved by the Institutional Review Boards and Ethics Committee of Peking University People's Hospital (Approval number: 2020PHB324-01). The results will be disseminated through national and international presentations and peer-reviewed publications.Trial registration numberNCT05020717.
