Insights
Comorbid conditions significantly increase healthcare utilization and medical costs for patients with systemic lupus erythematosus (SLE). Identifying these comorbidities is crucial for managing SLE patient care and reducing healthcare expenses.
Area of Science:
- Rheumatology
- Health Services Research
- Public Health
Background:
- Comorbidities increase mortality and healthcare costs in systemic lupus erythematosus (SLE).
- Understanding comorbidities linked to healthcare utilization is vital for SLE patient management.
- Emergency department visits and hospitalizations significantly impact medical costs for SLE patients.
Purpose of the Study:
- To investigate the association between comorbidities and healthcare utilization in SLE patients.
- To examine the relationship between comorbidities and medical charges for SLE patients.
Main Methods:
- Utilized Nebraska statewide emergency department and hospital discharge data from 2007-2012.
- Defined SLE using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code 710.0.
- Analyzed comorbid conditions in SLE patients compared to a non-SLE cohort.
Main Results:
- Patients with SLE exhibited more comorbid conditions than those without SLE.
- Common comorbidities for emergency department visits included pain, infections, and digestive symptoms.
- Frequent comorbidities for hospitalizations involved infections, cardiovascular diseases, COPD, and mood disorders.
- The number of comorbidities correlated significantly with longer hospital stays and increased hospital charges for SLE patients.
Conclusions:
- Comorbid conditions are demonstrably linked to increased healthcare utilization among SLE patients.
- Findings highlight the substantial impact of comorbidities on medical charges for SLE patients.
- This study underscores the importance of managing comorbidities to mitigate healthcare utilization and costs in SLE.
Background/Objectives:
In addition to increase mortality, comorbidities can increase medical costs for systemic lupus erythematosus (SLE). Healthcare utilization can dramatically increase medical costs. It is essential to better understand the comorbidities that can lead to healthcare utilization, such as emergency department visit and/or hospitalization, for SLE patients. Therefore, the objective of this study was to examine the associations between comorbidities and healthcare utilization and medical charges of patients with SLE.
Methods:
Nebraska statewide emergency departments (ED) discharge and hospitals discharge data from 2007 to 2012 were used to study the comorbid conditions of patients with SLE. SLE was defined using the standard International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosis codes (710.0).
Results:
There were more comorbid conditions in patients with SLE than patients without SLE. Comorbid conditions were majorly related to ED visits and hospitalizations of patients with SLE. Chest pain, abdominal pain, injury, acute respiratory infections, symptoms of digestive systems, headache, myalgia and myositis, noninfectious gastroenteritis and colitis, and symptoms of skin and other integumentary systems are common comorbid conditions for ED visits. Infections, cardiovascular diseases, fractures, chronic obstructive pulmonary disease (COPD) and allied conditions, cerebrovascular diseases, and episodic mood disorder are common comorbid conditions for hospitalizations of patients with SLE. In addition, the numbers of comorbid conditions were significantly associated with the length of hospital stay and hospital charges for SLE patients.
Conclusion:
The findings in this study indicated that comorbid conditions are associated with healthcare utilization and medical charges of patients with SLE.
