TB Programme Aims • To reduce avoidable morbidity and mortality associated with tuberculosis • To minimise the transmission of infection by early diagnosis and effective treatment • To prevent the emergence and spread of drug resistant TB • To ensure standardisation of TB management across Wales • To facilitate the continuous monitoring of local and regional trends in TB, in order that any identified change in incidence can be identified and addressed as necessary
Programme aims to be achieved by: • Promoting and facilitating best practice in the prevention and control of TB • Promoting a culture of collaborative working amongst health care professionals involved in the management of TB • Strengthening the provision of specialist microbiological TB diagnostic tests available in Wales • Further improving enhanced TB surveillance
Clinical Guidance • JCVI guidance on BCG vaccination in Green Book TB Chapter (updated on-line November 2007) – follow JCVI guidance for BCG vaccination • NICE TB Guideline, published March 2006 • Interdepartmental Working Group on Tuberculosis Guidance on the Prevention and Control of Transmission of HIV-related TB and drug-resistant TB (1998)
TB Services: • • • Clinical Radiology (Specialist) Microbiology Pathology Infection Prevention & Control Public Health – includes co-ordination of surveillance
Services need to be patientfocused • • Treatment for a minimum of 6 months Still a stigma in many communities Co-morbidity and social problems For inpatients in isolation with MDR-TB, maintain balance between need to protect others and the mental wellbeing of the patient, based on RA • Need to ensure that the patient and everyone involved in their care understands and is ‘signedup’ to the care plan
TB control • Early diagnosis especially of pulmonary disease important, so that treatment may be started promptly • Notify cases of TB disease on clinical suspicion by telephone, included those diagnosed PM (follow-up with formal notification on ETS form) • Be vigilant for TB especially in high-risk groups but remember anyone can get TB • TB can be a travel-related disease in people spending long periods of time in high-incidence countries
Effective management of TB requires: • An understanding of own roles and responsibilities, those of team members and other departments / sectors providing TB services • That TB nurse is informed of patients with TB • Knowing who has lead responsibility (cf incidents and clusters in community vs NHS Trust premises) • An appreciation of the risks of transmission in healthcare settings especially IP wards and OP settings • Knowledge & understanding of infection prevention and control measures, infection control policies, and their rationale • Collaborative working by everyone involved in TB control
Management of TB – special arrangements • • Access to TB specialist for advice Children People with HIV co-infection Patients with MDR pulmonary TB to be managed by TB specialists in centres with negative-pressure facilities – transfer arrangements to involve Infection Prevention & Control Team at referring and receiving hospitals • Commissioning services for Welsh residents receiving specialist TB services in England clinical support for contact tracing in Wales
Other issues • Management of human contacts of bovine tuberculosis
How will the NPHS TB Programme Group help? • Facilitate the provision of special TB microbiological services in Wales • Publish guidance and links to national guidance on the NPHS Intranet site: ²Framework document for BCG vaccination of infants and children aged up to under 16 ²Disseminate and promote the Framework for the provision of TB services for people living in Wales in the coming months, in liaison with Welsh Assembly Government • Undertake an audit of the implementation of the NICE TB Guideline in Wales in 2008 -09
In summary • Incidence of TB in Wales relatively stable year-on-year • Diagnose TB early by maintaining vigilance and investigating appropriately • Notify cases on clinical suspicion • Effective clinical management, underpinned by collaborative working essential to keep TB under control and to further reduce incidence
