Stopping Tuberculosis in EnglandAn Action Plan from the Chief Medical Officer

Action 1: Increased awareness

Aim: Maintain high awareness of TB, particularly among health professionals , highrisk groups and people who work with them, teachers, and the public

Five point plan > Produce multilingual and culturally appropriate public information and education materials for national and local use and make them widely available > Ensure that general practitioners and other primary and community care staff are aware of: the symptoms and signs of the disease; local TB services; and local arrangements for referring patients with suspected TB > Use World TB Day in March each year to increase awareness, particularly among healthcare professionals and high risk communities, and encourage relevant national organisations to do the same Maintain awareness, including through the media and community groups, and develop initiatives to support local awarenessraising among high risk groups Seek greater professional awareness through undergraduate, postgraduate and continuing professional education

Stopping Tuberculosis in EnglandAn Action Plan from the Chief Medical Officer

Action 2: Strong commitment and leadership

Aim: Create a strongly led, well coordinated and adequately resourced national TB programme, with all those working to deliver the programme having a clear focus on what needs to be achieved and best practice for doing this

Stopping Tuberculosis in EnglandAn Action Plan from the Chief Medical Officer

Action 3: High quality surveillance

Aim: Provide the information required at local, national and international levels to

• identify outbreaks

• monitor trends

• inform policy

• inform development of services, and monitor the success of the TB programme

Stopping Tuberculosis in EnglandAn Action Plan from the Chief Medical Officer

Action 4: Excellence in clinical care

Aim: Provide uniformly high quality, evidence based treatment and care for patients with suspected and diagnosed TB, with all patients having their outcome of treatment recorded and at least 85 per cent successfully completing treatment

Stopping Tuberculosis in EnglandAn Action Plan from the Chief Medical Officer

Action 5: Well organised and coordinated patient services

Aim: Provide high quality coordinated services for TB diagnosis, treatment and continuing care, which also meet the needs of individual patients

Action 6: First class laboratory services

Aim: Provide laboratory services of consistent high quality which support clinical and public health needs, in keeping with the overall pathology modernisation programme

Stopping Tuberculosis in EnglandAn Action Plan from the Chief Medical Officer

Action 7: Highly effective disease control at population level

Aim: Increase the evidence base for, and the consistency of application of public health interventions for TB

Action 8: An expert workforce

Aim: Ensure TB control has an appropriately skilled workforce and that physicians and nurses with expertise in TB continue to be recruited, trained and retained

Realizari pina in prezent

• 41 milloane de patienti vindecati, 1995-2009

• 6 milioane de decese prevenite comparativ cu standardele din 1995

• Mortalitatea reducsa cu 35% din 1990

• Vindecari >85%, ingijirea/HIV imbunatatita

• But…. TB incidence declining too slowly, case detection stagnating, and MDR-TB care only now starting scale-up

Imbunatatirea controlului TB

1. Remove financial barriers (UHC)2. Ensure well trained and sufficient human resources3. Establish a network of labs where rapid tests are also

available4. Ensure availability of quality drugs5. Regulate the use of all anti-TB drugs6. Introduce infection control7. Establish proper surveillance8. Promote R&D9. Mobilize resources domestically and internationally

Document WHA 62.15, 2009

•Public and private medical colleges (yellow) diagnose a huge number of cases, but many of them are from outside the city and need to be refereed for treatment elsewhere.

•The increase in diagnosed cases represents increased notification after medical colleges and other providers started to report to NTP in a standardised way

Bangalore, 1999-2005

Cresterea numarului de notif icari

Limitari ale diagnosticului, medicamentelor, vaccinului

Diagnostics - More than 100 years old • Detects only half of the cases in patients tested• Ineffective for diagnosing TB in PLHIV• Rapid tests for MDR strains available, but not yet in the field

Drugs – Last drug 40 years old • Four drugs, taken for at least 6 months• Not compatible with some HIV/AIDS antiretrovirals• MDR-TB treatment lengthy, with low cure rates, expensive, toxic

Vaccine – Nearly 90 years old• Unreliable protection against pulmonary TB• No apparent impact on the TB epidemic
