Pneumonia surveillance in Thailand: current practice and future needs

Area of Science:

• Public Health
• Epidemiology
• Infectious Disease Surveillance

Background:

• Pneumonia surveillance in Thailand has been ongoing since 1975.
• Reported pneumonia cases and deaths have shown an increasing trend since the mid-1980s.
• The effectiveness of the current pneumonia surveillance system requires evaluation.

Purpose of the Study:

• To evaluate the pneumonia surveillance system in Thailand.
• To analyze detailed pneumonia surveillance data from Sa Kaeo Province (1999-2001).
• To compare surveillance data with death certificate data and assess personnel knowledge.

Main Methods:

• Review of reported pneumonia cases and deaths in Thailand since 1975.
• Detailed analysis of electronic surveillance data from Sa Kaeo Province (1999-2001).
• Comparison of surveillance-reported deaths with death certificate data (1999-2000).
• Interviews with surveillance personnel from hospitals and health centers.

Main Results:

• An average of 925 pneumonia cases reported annually in Sa Kaeo, with incidence peaking in children under 5.
• Significant underreporting of pneumonia deaths through surveillance compared to death certificates (7-6 vs. 28-53).
• Inconsistent knowledge of diagnostic criteria among surveillance personnel, despite established guidelines.

Conclusions:

• The pneumonia surveillance system in Thailand demonstrates significant underreporting of deaths.
• Gaps in training and understanding of diagnostic criteria among surveillance personnel impact data accuracy.
• Improvements in training and standardized application of diagnostic criteria are crucial for enhancing pneumonia surveillance effectiveness.
