Insights
Pyogenic arthritis (PA) affects hospitalized patients, with higher prevalence in older adults. Chronic liver disease and infections predict poorer outcomes in PA patients.
Area of Science:
- Epidemiology
- Rheumatology
- Public Health
Background:
- Pyogenic arthritis (PA) remains a significant cause of hospitalization.
- Understanding its epidemiological patterns and treatment outcomes is crucial for effective management.
Purpose of the Study:
- To investigate the epidemiological characteristics of hospitalized pyogenic arthritis patients in Thailand.
- To identify predictors of treatment outcomes for these patients.
Main Methods:
- Analysis of a nationwide hospital database from the 2010 fiscal year.
- Inclusion of patients aged 18 and above with a primary diagnosis of pyogenic arthritis.
Main Results:
- 6242 PA admissions were recorded in 2010, ranking third among musculoskeletal conditions.
- Prevalence was 13.5 per 100,000 adults, increasing with age and concentrated in northern/northeastern Thailand.
- Diabetes was the most common comorbidity; chronic liver disease and existing infections were associated with poorer outcomes.
Conclusions:
- Hospitalized pyogenic arthritis prevalence in Thailand is moderate, peaking in older age groups.
- Diabetes is a frequent comorbidity, but chronic liver disease and multiple infections indicate worse prognosis.
Background:
Pyogenic arthritis (PA) is still a problematic arthritic disease that requires hospitalization.
Objective:
To study the epidemiological characteristics and predictors of treatment outcomes for Thai patients hospitalized with PA.
Materials And Methods:
The nationwide hospital database from the 2010 fiscal year was analyzed. Patients 18 years of age onward, who had primary diagnosis of pyogenic arthritis, were included in this study.
Results:
There were a total of 6242 PA admissions during 2010. It was ranked third among hospitalized musculoskeletal patients after osteoarthritis (OA) and gouty arthritis. The estimated prevalence of PA was 13.5 per 100 000 adult population. Geographic distributions of PA was related to the population density of each region; however it seemed more frequent in the northern and northeastern regions of Thailand. The prevalence increased with age, 3.6 and 43.6 per 100 000 in young adults and the elderly, respectively. Among the 2877 co-morbidities coded, diabetes was the most common, followed by crystal-induced arthritis, existing other foci of infections (urinary tract infection, skin and soft tissue infections and pneumonia) and pre-existing chronic joint diseases (OA,rheumatoid arthritis), respectively. Overall hospital mortality rate was 2.6%. Poorer outcomes were found among patients with chronic liver disease and other existing foci of infections.
Conclusions:
The prevalence of hospitalized PA is still modest in Thailand, showing the highest prevalence in the advanced age group. Diabetes was the most commonly co-morbidity found; however, poorer outcomes were noted among patients with chronic liver disease and existing multiple sites of infections.
