RESUMEN

OBJETIVO:

Se busca establecer la Sensibilidad Especificidad Valor Predictivo Positivo VPP y Valor Predictivo Negativo VPP de la prueba IVAA Inspección visual con ácido acético, en pacientes del Área rural de Bolivia, comparados con el PAP, Papanicolaou, durante las gestiones 2012 a 2014. MATERIAL Y

MÉTODOS:

Previa capacitación a los operadores. Estudiantes de quinto año de medicina, En base a un diseño de ensayo comunitario, Se procedió a la toma de muestras siguiendo el siguiente protocolo 1 Toma de muestra de PAP, mediante espátula de Ayre 2 Aplicación del test IVAA 3 Caso IVAA positivo----Colposcopia inmediatamente, por especialista 4 Si COLPOSCOPIA positiva ----BIOPSIA ( Prueba de oro) 4 Caso Negativo---Espera resultado PAP 5 Recopilación de datos Análisis de la información en base de datos Excel 7 Presentación de resultados.

RESULTADOS:

551 pacientes entre 15 y 65 años que residen en área rural de Bolivia fueron estudiadas. La prevalencia de casos verdaderamente positivos fue de 4.11%. La Sensibilidad del IVAA o sea su capacidad para diagnosticar fue de 100% y su Especificidad de 84% Sus valores VPP y VPN para IVAA fueron 25% y 87% respectivamente. En cambio el PAP presenta una Sensibilidad de apenas 16% y una Especificidad de 96% Sus valores VPP y VPN son 13% y 93%.

DISCUSION:

Una alta prevalencia de casos verdaderamente positivos se encuentra en este estudio Se ratifica la alta sensibilidad para el diagnóstico de verdaderamente enfermos por la prueba IVAA en una sola sesión, factible en áreas rurales.
ABSTRACT
OBJETIVE It seeks to establish Sensitivity Specificity positive predictive value VPP and negative predictive value PPV of VIA test visual inspection with acetic acid in patients from rural areas of Bolivia, in the highlands Copacabana, semi plains Coripata, Chulumani and plains, San Borja and Riberalta in the Plurinational State of Bolivia, compared with PAP smear during the steps 2012 to 2014. MATERIAL AND

METHODS:

After training to operators. Students fifth year of medicine escole, both the PAP sampling, technique and visual inspection with acetic acid and collecting epidemiological information. EMCN design community trial, we proceeded to the sampling in rural areas, in a single session using the following protocol 1 Sampling of PAP, by Ayre spatula 2 Application of the test VIA (acid application acetic 5% vinegar on a cotton swab for 1 minute and then observing with lighting 100 watt bulb 3 Case VIA positive Colposcopy immediately, Specialist 4 If COLPOSCOPY positive BIOPSY ( Gold standart) 4 If not Wait --- PAP result 5 Collecting data 6 Information analysis in Excel database. 7 Presentation of results.

RESULTS:

551 patients between 15 and 65 who live in rural area of Bolivia were student the prevalence of cases truly positives was 4.11%. The sensitivity of VIA or their capacity to diagnose was 100% and specificity of 84% Their PPV and NPV for VIA values were 25% and 87% respectively. In contrast, the PAP has a sensitivity just 16% and a specificity of 96% Their PPV and NPV values are 13% and 93%.

DISCUSION:

A truly high prevalence of positive cases found in this study in the rural area. High sensitivity for the diagnosis of truly sick is ratified by the VIA test in one session, feasible in rural areas, because the PAP did not match the VIA in most cases, it remains to follow up the second level, colposcopy positive chaos diagnosed by PAP 3.26%, which could increase the prevalence of truly positive cases in the rural area. This study suggests pursue new strategies for the detection, diagnosis and treatment particularly in women living in rural area and do not have easy access to care centers II or III level.
