1 Progress in the Implementation of Collaborative TB/HIV Activities Contribution of TB Infection Control Subgroup 3 November 2009

2 Key contributions Ensure that health care facilities providing services for people living with HIV have infection control practices that include TB infection control Ensure prevention of TB transmission to health care workers, employed in facilities providing care for people living with HIV IC indicators from A guide to monitoring and evaluation for collaborative TB/HIV activities

3 2009 WHO TB infection control policy Online version found as follows: _eng.pdg Printed versions available and being distributed Policy being translated into different languages Aide memoires being prepared

4 2009 WHO TB infection control policy Addresses health facilities, congregate settings and households Adds a managerial component at the national and facility level Promotes the role of the civil society in designing, implementing and evaluating TB IC Promotes synergies between TB infection control and general infection control, and with the health system Emphasizes community involvement in raising awareness, promoting behavior change, reducing stigma Recommends a combination of controls based on facility assessments

5 Managerial activities Identify or strengthen a coordinating body Develop a comprehensive and budgeted plan Ensure health facility design, construction or renovation Conduct surveillance for TB disease among HCWs Address advocacy, communication and social mobilization Conduct monitoring and evaluation Enable operational research

6 Health care facilities Health facility level managerial activities Administrative controls Environmental controls Personal protective equipment

7 Administrative controls Strategies to promptly identify potentially infectious cases (triage), separate them, control the spread of pathogens (cough etiquette) and minimize time in health care settings 1) Triage 2) Separation 3) Cough etiquette 4) Minimize time in health care settings

8 TB triage for patients needing hospitalization, Haiti Partners in Health General ward Smear HIV + or TB Pavilion Smear + HIV 6 isolation rooms Smear + and HIV +

9 Separation of respiratory patients

10 Cough hygiene

11 Protection of HCWs Encourage TB diagnostic investigation when signs and symptoms suggestive of TB occur or when exposed to smearpositive and culture-positive TB patients Encourage HIV testing If HIV-positive, make available a package of care, including IPT, ART, if needed, job relocation, and screening for TB

12 Environmental controls Use of ventilation systems Use of ultraviolet germicidal irradiation (UVGI) fixtures, at least when adequate ventilation cannot be achieved

13 Natural ventilation Plan of Respiratory wards, Santa Rosa 3 Office Nurses Balcony Unoccupied ward General respiratory ward Balcony Balcony Drug-sensitive TB MDR-TB Isolation room

14 Use of open air spaces

15 Personal protective equipment Use of particulate respirators is recommended for health workers when caring for patients or suspects with infectious TB In particular, health workers should use respirators: during high-risk aerosol-generating procedures associated with high risk of TB transmission (e.g. bronchoscopy, intubation, sputum induction procedures, aspiration of respiratory secretions, and autopsy or lung surgery with high-speed devices) when providing care to infectious MDR-TB and XDR- TB patients or people suspected of having infectious MDR-TB and XDR-TB.

16 Prioritization of TB IC measures Choice of controls or a combination of controls should be based on a comprehensive TB IC facility assessment Consider epidemiological, climatic, socioeconomic conditions, and estimated costs Specific recommendations for high HIV prevalent settings and for MDR-TB and XDR-TB.

17 Congregate settings Prisons, jails, military barracks, homeless shelters, refugee camps, dormitories and nursing homes. Each facility differs in type of population and duration of stay of the dwellers.

18 Congregate settings Avoid overcrowding Focus on DOT in prisons. Be part of the national planning and assessment of facilities. Recommendations are less specific than those for HCF. Recommendations on medical services as per HCF. Long-term stay (prisons) and short term stay (jails)

19 Households Importance of early case detection and TB contact investigation Emphasis on behaviour-change campaigns for patients and families of smear/culture positive patients Focus on cough etiquette and respiratory hygiene and to spend as much time as possible outside Use of respirators by HWs in specific situations Renovation of houses for MDR and XDR TB

20 From policy to implementation Additional tools and guidance documents: work of the TB IC Subgroup Implementation framework Advocacy strategy Costing of the TB IC policy recommendations Standards and specifications of TB IC equipment Case design book

21 Framework How to implement the recommendations of the TB IC policy Best practice examples Example of roles and responsibilities Tools Checklists Sample IEC materials

22 Advocacy Draft document with recommendations to support policy adoption and dissemination Contains detailed information on priority target groups Key messages for each audience Specific actions to be taken Opportunities to reach the target groups

23 Costing Estimates cover the period from Different scenarios for MDR-TB and TB in the 27 high burden MDR countries, plus an additional 9 TB HBCs, not already in the model Promotion of community care approaches Budget estimates vary from 758 to 4,546 million USD

24 Costing cont. Assumptions underlying the model being validated by countries implementing TB IC activities Costing estimates to guide refinement of the WHO planning and budgeting tool Costing model to be made available for country adaptation and use Cost estimates to be included in the Global plan revision

25 Standards and specifications WHO prequalification does not apply to commodities Demand from countries for guidance on purchase of TB IC equipment (respirators, UVGI, fans) Document will enable countries to make informed choice on purchases

26 Case design book Being prepared by graduates from the Harvard course on engineering methods for the control of airborne infection..class of 2008 Examples of facility designs with adequate ventilation, in different climatic conditions Use of outdoor spaces, when feasible Simple examples of the use of prevailing winds, cross ventilation, and space.
