The Development of Operational on Prevention and Control Surveillance tuberculosis Model, Nong Bua Lamphu Province Network
Keywords:
Tuberculosis, Action research, Proactive screening, Surveillance model, Health networkAbstract
This action research aimed to investigate operational problems, develop a model, and evaluate the implementation outcome of the tuberculosis (TB) surveillance, prevention, and control model within the Nong Bua Lamphu Health Network. Key informants comprised 120 healthcare providers, 7 experts who validated the research instruments, and 24,739 individuals in risk groups. The study was conducted from November 2025 to August 2026. Data were collected using recording forms, questionnaires, and focus group discussion guides, all exhibiting content validity (IOC ranging from 0.80 to 1.00). Data were analyzed using frequencies and percentages.
The research findings revealed the following: (1) Previous operations revealed major challenges across three key dimensions: (1) Screening: proactive screening systems remained incomplete, frequently missing hidden populations, mobile workers, and hard-to-reach target groups; (2) Diagnosis: primary care units (Sub-district Health Promoting Hospitals) faced a shortage of rapid diagnostic tools, resulting in delayed case detection; and (3) Patient Care: inconsistent medication adherence among a subset of patients elevated the risk of treatment failure and the emergence of drug resistance. (2) The developed operational model encompasses six key components: strategy formulation and resource allocation, proactive screening and community referral, technology-driven precise diagnosis, treatment supervision and complex case management, real-time data management, and quality review alongside supportive supervision. (3) Model evaluation demonstrated that proactive TB screening coverage among high-risk populations using chest X-rays (CXR) reached 95.78% (34,493 out of the target 36,014 individuals). The registration coverage rate for new and relapse TB cases reached 66.61% (465 out of an estimated target of 698 cases), and the treatment success rate among new pulmonary TB cases reached 96.25% (77 out of 80 patients).
