Latent TB screening and management in accordance with the Heath surveillance protection centre (HSPC) guidelines is imperative for patient safety and public health. A clinical audit was performed in the TB services of a large teaching hospital in Dublin. The audit measured wait times from referral to diagnosis and compliance with the components of the HSPC guidelines; The results revealed variance in
compliance with the HSPC guideline for the screening process and the management process of Latent TB. The variation in the screening process led to delays in the
diagnosis and treatment of patients. In addition to the non-standardised screening and management, various specialties were following different guidelines for the
screening of Latent TB. This resulted in poor compliance with the HSPC guideline.There is evidence in the literature which demonstrates the negative impact of unscreened patients, untreated patients and nonadherence to the clinical guidelines in the healthcare organisation. The focus of this Quality Improvement (QI) project is to Improve the adherence with the HSPC guideline in order to reduce variation in the screening and management of Latent TB patients. The lean Six Sigma DMAIC approach was applied in the QI to identify the root causes and improvement measures required for change. Based on the data collected and the literature, a QI plan was devised to target the root causes of the problem. The interventions aim to increase staff awareness on Latent TB and the HSPC guidelines by providing staff education and materials.
