Annex 9. Checklist for the review of programmatic implementation of tuberculosis infection prevention and control

This checklist was prepared for the express purpose of national tuberculosis (TB) programme reviews for TB infection prevention and control (IPC) (1,2). Such reviews typically consider multiple programmatic components; thus, a checklist helps the reviewer to focus on the critical areas of any particular component.

Objectives

Annex 8. Choosing a radiometer for measurement of ultraviolet C irradiation

The manufacturer’s specifications should be checked to determine whether the radiometer has the appropriate characteristics for wavelength, irradiance measurement and accuracy, based on the ultraviolet C (UVC) source being used (1)

Wavelength range

The radiometer chosen should be able to measure wavelengths of 220–280 nm with a peak response at 254 nm for standard UVC254 low-pressure mercury lamps.

Annex 7. How to choose upper-room germicidal ultraviolet light fixtures

The scenarios in this annex are designed to aid in choosing the most appropriate and cost-effective germicidal ultraviolet light features; that is, features using ultraviolet C (UVC) to create an effective upper-room UVC254 system. The effectiveness of the system depends on room shape and dimensions, type of fixtures available and how occupants will use the space. The three examples given demonstrate how these factors can influence final fixture choices for upper-room UVC (1).

Annex 2. Facility tuberculosis risk assessment tool

This annex is based on a tool produced by Médecins Sans Frontières (MSF) (1).

Instructions: This tool helps to give an idea of the risk of transmission of Mycobacterium tuberculosis in health care facility or congregate settings. The results should be completed by the infection prevention and control (IPC) focal person and interpreted by the IPC committee. For the Yes/No questions, a Yes answer indicates good tuberculosis (TB) IPC practices. Any pertinent information on No answers is noted in the Comments section below each table.
