Instruments, consumables, and setup required for examination after application of acetic acid Ė Instruments and consumables required
One of the key advantages of VIA or using acetic acid to determine eligibility for treatment is that no specialized instruments are required (other than those that are readily available in primary health-care settings) and the consumables are inexpensive and readily available. Screening programmes that support the screen-and-treat protocol should make treatment facilities with ablative methods (cryotherapy and/or thermal ablation) available at the screening clinics.
The following equipment and instruments are required:
The consumables required for the examination are the following:
In addition to the equipment and the consumables, screening forms and registers are needed for documentation of test findings and future follow-ups. In some clinics a computerized record-keeping system may be used.
Use of magnification devices to assist visual examination:
Several devices are available to visualize the cervix on the screen of a mobile phone or a tablet. Such compact and affordable devices have a built-in battery-powered light source, focusing facilities, and the capacity to view and magnify images on the screen of the mobile phone or tablet. In some countries in Africa, a camera with a zoom lens and an autofocus facility is used to capture the cervical images and transmit them to a television monitor connected through a cable. A few studies have evaluated such devices and reported improved accuracy of VIA or determining eligibility for ablative treatment. The captured images can be used for teleconsultation, quality control, and training. Studies are in progress to evaluate the use of artificial intelligence algorithms to interpret the images Ė a technique called automated visual examination (AVE).
