Spanish version of the readiness for interprofessional learning scale (RIPLS) in an undergraduate health sciences student context.

The Readiness for Interprofessional Learning Scale (RIPLS) has been widely used to measure students' and professionals' attitudes toward interprofessional learning. However, inconsistencies have been reported concerning its validity and reliability. This study aimed to translate, adapt, and validate the RIPLS questionnaire to be applied to Spanish-speaking health sciences students in Chile. Content and construct validity evidence of the newly created Spanish version of the RIPLS scale were analyzed. An exploratory (EFA) and confirmatory (CFA) analysis were conducted, determining goodness-of-fit indexes. Reliability was evaluated through Cronbach's Alpha Coefficient. We assessed sensitivity to change of the RIPLS scale by comparing pre- and post-interprofessional education workshop scores. The EFA showed that there were three factors. In the CFA, most of the standardized factor loadings were higher than 0.3. Regarding internal consistency, Cronbach's Alpha was 0.86. The differences between the total RIPLS scores before and after the workshops were statistically significant. The Spanish version of RIPLS showed evidence of validity and reliability for use amongst health sciences students. The construct was adequately measured and was shown that it could be used to assess the impact of interprofessional education workshops.

HIV Testing Among Heterosexual Hispanic Women in South Florida.

PURPOSE: The purpose of this study was to examine the influence of selected facilitators, barriers, beliefs, and knowledge suggested by the literature to be associated with human immunodeficiency virus (HIV) testing among heterosexual Hispanic women. DESIGN: This study utilizes a cross-sectional design to analyze secondary data from SEPA III: The Effectiveness Trial. SEPA stands for Salud, Educacion, Prevencion y Autocuidado, which translates to Health, Education, Prevention, and Self-Care. The Social Cognitive Model (SCM) guided this study. METHODS: Three hundred twenty heterosexual Hispanic women 18 to 50 years of age participated in this study. Data were analyzed using descriptive statistics and logistic regression. FINDINGS: The most common facilitators for HIV testing were receiving recommendations from a healthcare provider (HCP) and the test is offered by an HCP rather than women asking for it. The most common barrier to testing was having no reason to believe they were infected. Most women believed a positive test result would encourage them to take better care of themselves. However, as much as 15% of women reported desires to kill or hurt themselves if they test positive. On the other hand, a negative result would make them assume their partners are negative and thus do not need to be tested. Significantly, explanatory variables related to HIV testing were knowledge and the HIV test is offered by an HCP instead of women asking for it. CONCLUSIONS: Strengthening HIV knowledge and offering HIV tests are significant contributions that nurses make to the health of Hispanic women. The SCM can be used to design programs to increase HIV testing among Hispanic women. CLINICAL RELEVANCE: Nurses are encouraged to offer testing and provide culturally competent HIV prevention education to increase HIV testing among Hispanic women.

Exploring the Masculine Identity in the Context of HIV Prevention in Chile.

PURPOSE: This study aims to describe human immunodeficiency virus (HIV)-related knowledge and beliefs, as well as understanding attitudes towards masculinity in the context of HIV prevention, held among Chilean men. DESIGN: This study reports the qualitative findings of a sequential qualitative-quantitative mixed methodology study: Bringing men into HIV Prevention in Chile, NIH R01 TW007674-03. METHODS: Twenty in-depth interviews using a qualitative, descriptive approach to elicit information for the study were conducted among men residing in two communities of low socio-economic status in Santiago, Chile. FINDINGS: Content analysis of interviews revealed three main themes regarding machismo and how it relates to HIV: sexuality and machismo, the changing nature of machismo, and violence against women. CONCLUSIONS: Addressing HIV and intimate partner violence through developing education programs tailored to meet the needs of Chilean men are needed to include men in HIV prevention efforts. CLINICAL RELEVANCE: Specifically, incorporating ideas of what men consider healthy masculinity and working to destigmatize men who have sex with men are important steps in addressing the negative aspects of machismo.

Predictors of readiness for oral rapid HIV testing by Chilean health care providers.

OBJECTIVE: This study identified the personal characteristics that affect Chilean health care providers' readiness to adopt HIV Oral Rapid Testing (ORT) in Chile as a new clinical evidence-based practice (EBP). METHODS: Using a cross-sectional research design, the study sampled 150 nurses, midwives, and physicians employed at four clinics within the Pontifícia Universidad Católica de Chile Health Network in Santiago. Participants completed a self-administered survey asking about their demographic background, EBP attitudes and experience, personal beliefs related to HIV, the importance of HIV testing, and perceived self-comfort in performing a rapid HIV test. RESULTS: Of the participants, 90% believed that incorporating ORT would make a positive difference in their practice and said that they would be willing to adopt the technology for that reason. Nonetheless, the providers reported a mean "readiness to implement ORT" score of 15.1 out of a possible value of 20, suggesting only moderate self-perceived readiness to adopt the EBP. Education, beliefs about evidence-based practice, perceived comfort in performing ORT, and perceived importance of HIV testing explained 43.6% of the variance in readiness to adopt ORT. CONCLUSION: The findings of this first ORT pre-implementation study in Chile can help guide policy makers and HIV stakeholders to prepare for and increase primary health care providers' readiness to successfully adopt this evidence-based technology. Successful adoption of ORT could increase Chile's capacity to reach HIV-vulnerable Chileans for testing and referral to care if infected, thus helping the country to reduce further transmission of the virus and its medical complications.

Oral rapid test: an alternative to traditional HIV screening in Chile.

OBJECTIVE: To compare the sensitivity and specificity of an Oral Rapid Test (ORT) to that of the Enzyme-Linked Immunosorbent Assay (ELISA) for HIV testing in Santiago, Chile; to track the number of study participants returning for ELISA testing results; and to analyze the participants' perceptions of the ORT compared to the ELISA. METHODS: A total of 497 people were recruited in Santiago, Chile: 153 had previously tested positive for HIV, and 344 were of unknown status. Participants were tested for HIV using both the ELISA and the ORT to examine and compare specificity and sensitivity. Qualitative data were collected from 22 participants to compare perceptions of the testing experience with ORT versus ELISA. RESULTS: The ELISA reported 184 (37%) of the 497 participants as being "positive" for HIV antibodies; the ORT showed 181 (36.4%) as being "reactive" for HIV. The ORT showed a sensitivity of 98.4% (95.7%-99.9%, 95% Confidence Interval) and specificity of 100%. The Kappa test produced K = 0.983 (P < 0.0001). Of the 344 participants whose HIV status was unknown at the start of the study, 55 failed to return for their ELISA results. Participants positively perceived ORT as having reduced both waiting time and anxiety over obtaining their test results. ORT oral swabbing appeared more practical and less invasive than drawing blood for the ELISA. CONCLUSIONS: The ORT and ELISA were statistically equal in specificity and sensitivity. ORT provides quicker results, potentially ensuring that more people receive them, and does not require handling of or exposure to potentially hazardous blood products.

HIV-Related Stigma and Multidimensional Frailty Among Older Latinos With HIV.

Introduction: Frailty is a geriatric syndrome of increased vulnerability to stressors marked by a higher risk for poor health outcomes. HIV-related stigma is a stressor for Latino people with HIV (PWH) and an important barrier to HIV care. This study examines the association between HIV-related stigma and multidimensional frailty among older Latino PWH. Methods: A cross-sectional design with 120 Latino PWH aged 50 and older was used. Self-reported questionnaires were administered to assess multidimensional frailty (Tilburg Frailty Indicator) and HIV-related stigma (HIV stigma scale). Results: Participants were 59.1 ± 7.0 years old, primarily White-Hispanic (85.00%, n = 102), single (48.33%, n = 58), and male (73.30%, n = 88). Nearly half of the participants were frail (45.85%, n = 55). Compared to non-frail, frail individuals had significantly higher scores in the total HIV-related stigma (M = 98.5 ± 24.7 vs. M = 85.3 ± 25.6, p = .020) and all subscales. The odds of multidimensional frailty were 1.021 times higher for people with higher HIV-related stigma scores (p = .007). This association remained significant after adjustment for income and comorbidities (p = .049). Conclusions: HIV-related stigma among older Latino PWH was significantly associated with their odds of being frail. Efforts to prevent multidimensional frailty should consider addressing HIV-related stigma through age-appropriate and culturally tailored resources for this group.

Mano a Mano-Mujer: an effective HIV prevention intervention for Chilean women.

The impact of a professionally facilitated peer group intervention for HIV prevention among 400 low-income Chilean women was examined using a quasiexperimental design. At 3 months postintervention, the intervention group had higher HIV-related knowledge, more positive attitudes toward people living with HIV, fewer perceived condom use barriers, greater self- efficacy, higher HIV reduction behavioral intentions, more communication with partners about safer sex, and decreased depression symptoms. They did not, however, have increased condom use or self-esteem. More attention to gender barriers is needed. This intervention offers a model for reducing HIV for women in Chile and other Latin American countries.

[Effectiveness of an educational program about the Chilean AIDS law in primary care health workers]. / Eficacia de una intervención educativa sobre conocimientos de ley chilena de SIDA en trabajadores de salud primaria.

BACKGROUND: In Chile, members of the civil society and government achieved the passing of the HIV/AIDS Law (19.779). The level of knowledge of the law held by healthcare workers in Chile is not well known. AIM: To analyze the effect of an intervention on knowledge of the existence of the law and its application in clinical practice among primary healthcare workers in southeastern Santiago. MATERIAL AND METHODS: Healthcare workers of primary care centers were invited to participate in the study. One group received an educational intervention lasting a total of 16 hours, about AIDS physiopathology, sexually transmitted diseases, communication with patients and current legislation. A control group did not receive the educational intervention. Both groups answered a self-administered questionnaire about the HIV/AIDS law at baseline and three months after the intervention. RESULTS: The intervention was carried out in 262 workers and 293 participated as controls. The initial evaluation revealed that only 16.3% (n = 89) had heard of the law, without any significant difference between intervention and control groups. The knowledge about the law improved by 65% in the intervention group and did not change in controls. At the end of the education period, the intervention and control groups improved their global knowledge by 29 and 3%, respectively (p < 0.05). CONCLUSIONS: The educational intervention was effective in improving knowledge of the HIV/AIDS Law among Chilean healthcare workers.

Chilean Health Care Providers' Perceived Comfort in Performing Oral Rapid Testing for HIV: A Cross-Sectional Study.

OBJECTIVES: To understand key factors influencing Chilean health care providers' perceived comfort performing oral rapid HIV testing. DESIGN: One hundred and fifty health care providers completed a self-administered questionnaire that included a five-item scale measuring self-perceived comfort in conducting HIV pretest counseling, oral rapid testing, finger-prick testing, and delivering test results. RESULTS: Most participants (60%) envisioned good overall comfort performing oral rapid HIV testing (mean score of 16.21; range 0-20), including doing at least four of the five steps. They perceived least comfort delivering HIV-positive test results during posttest counseling. HIV stigmatizing attitudes reduced self-perceived comfort. CONCLUSIONS: Providing training to counter HIV stigmatization while increasing comfort in performing oral rapid testing would help facilitate its successful implementation.

Observed use of standard precautions in Chilean community clinics.

OBJECTIVES: In Chile, little information about the use of standard precautions (SP) among health care workers (HCWs) exists. As part of a larger study to tailor and test an HIV prevention intervention for community HCWs, this study describes the observed frequency with which appropriate SP were used by HCWs in low-income community clinics of Santiago. Also, the availability of supplies is described. SAMPLE: A total of 52 structured observations with potential contamination with body fluids were done. RESULTS: HCWs used SP inconsistently, especially neglecting hand washing, surface cleaning, and cleaning of shared materials. Lack of materials contributed in some instances of failure to use SPs, especially wiping surfaces and safe disposal of sharp instruments, as shown by a positive correlation between use of SP and availability of materials. Essential materials were usually available. Although more education should relate to a better understanding of the importance of SP, no difference was found between professionals and paraprofessionals in the use of SP. CONCLUSIONS: It is clear that the initial training, continuing education, and ongoing support for practicing SP are not adequate. Training should be offered to HCWs involved in caring for clients at community clinics to stop the spread of HIV or other infectious diseases in health care settings.

Disposición de profesionales de la salud chilenos hacia la consejería breve anti-tabaco en pacientes hospitalizados de una institución privada / Readiness of chilean healthcare professionals towards brief tobacco cessation counseling in hospitalized smoking patients of a private institution

OBJETIVO: Evaluar la disposición pre y post intervención de profesionales de la salud de una consejería breve antitabaco (CBA) para pacientes fumadores hospitalizados. MATERIAL Y MÉTODO: Estudio cuantitativo, descriptivo correlacional de corte transversal, con 65 sujetos participantes. RESULTADOS: El 84,6% de los participantes son mujeres, con edad promedio de 33.8 años (DS±9,1). El 52,3% se desempeñaba como técnico en enfermería, seguidos por los enfermeros(as) (18,5%). El 34,9% de los sujetos eran fumadores, de ellos el 21,6% fumaba entre 1 y 5 cigarrillos diarios. Se observó mayor disposición y aceptabilidad hacia la CBA en los proveedores de salud que no fuman versus los fumadores en la medición basal. Post intervención hay diferencias significativas n el grupo de profesionales fumadores, mejorando su disposición y aceptabilidad hacia la CBA. CONCLUSIONES: A mayor consumo de tabaco en los proveedores de salud, menor es la disposición, la aceptabilidad y la conducta habitual de realizar la CBA a los pacientes adultos hospitalizados. Una intervención de CBA dirigida a personal fumador ha demostrado ser efectiva en mejorar su disposición. Si bien el ser fumador constituye una barrera de implementación, es algo que se puede mejorar con capacitación, por lo que se invita a tomar en considerar el nivel de consumo de tabaco de los funcionarios en futuras intervenciones de CBA en pacientes hospitalizados.

OBJECTIVE: To assess readiness among healthcare providers in pre- and post- brief tobacco cessation counseling (BTCC) intervention for hospitalized smoking patients. MATERIAL AND METHOD: Quantitative, descriptive, cross-sectional correlational study, with 65 participants. RESULTS: 84,6% of the participants are women, with an average age of 33,8 years (DS9,1). 52,3% work as nursing technicians, followed by nurses (18,5%). 34,9% of the participants are smokers, of which 21,6% smoke between 1 and 5 cigarettes a day. Greater readiness and acceptability towards BTCC are observed in non-smoking healthcare providers. Significant differences are found in the post BTCC intervention group of smoking healthcare providers, improving their readiness and acceptability towards BTCC. CONCLUSIONS: The greater the tobacco consumption of healthcare providers, the lower readiness, acceptability, and common practice of performing BTCC on hospitalized adult patients. A BTCC intervention aimed at smoking healthcare providers has been shown to be effective in improving their readiness. Although being a smoking healthcare provider has shown to be a barrier to BTCC implementation, it is something that can be overcome with intervention, which is why it is important to consider the level of tobacco consumption of healthcare providers in future implementation of BTCC in hospitalized patients.

Chilean university students: knowledge and concern about HIV/AIDS.

According to a 2004 report by the Joint United Nations Programme on HIV/AIDS, Chile has an incipient HIV/AIDS epidemic. Regardless of the classification, every year the cumulative incidence of HIV/AIDS increases. Young Chileans have been the most affected group; still, their knowledge, attitudes, and concerns about HIV/AIDS are not known. This study describes Chilean university students' HIV/AIDS-related knowledge, their worry about getting the virus, and the correlation between both variables. A convenience sample of 45 university students responded to an anonymous self-administered questionnaire after orally consenting to participate in this study. Overall, students had good levels of HIV/AIDS-related knowledge, with 77% responding correctly to at least 85% of the questions. Despite this knowledge, almost 56% of students stated that they were not worried about getting HIV/AIDS. The situation was corroborated by a nonsignificant statistical correlation between both variables (p > .05). These results are congruent with literature from other countries and strengthen the need for further research to clarify why university students, the majority of whom are well-educated and engage in behaviors that place them at risk for contracting the virus, do not worry about HIV.

EXPLORING SELF-EFFICACY AND PERCEIVED HIV RISK AMONG SOCIOECONOMICALLY DISADVANTAGED HISPANIC MEN.

The prevalence of HIV in Chile predominately affects the male population with the primary mode of transmission (99%) through sexual contact. In order to engage in safe sexual practices, men must have high sexual self-efficacy and perceived risk of infection, however, little research examines these variables with respect to HIV prevention. The purpose of this article is to review existing literature on self-efficacy and its connection with perceived HIV risk among Hispanic men, in order to direct future HIV prevention interventions among Chilean men. A literature search was conducted to identify studies for this review using three databases. A combination of keywords was used to conduct the search and a total of 34 articles were analyzed. All of the articles reviewed examined the Hispanic male population with respect to either self-efficacy or perceived risk, or a combination of the two. Major themes emerging from the review include: substance use, condom use, cultural norms, relationship communication, negotiation, and homonegativity. The existing studies provide evidence for preventing future HIV infection among low socioeconomic status Chilean males and begin to establish a positive relationship between self-efficacy and perceived HIV risk. While additional studies are needed to provide further support, self-efficacy and perceived risk should be integral aspects of future prevention interventions.

Mujeres que Consumen Sustancias y su Vulnerabilidad frente al VIH en Santiago de Chile (Women Who Consume Substances and Their Vulnerability to HIV in Santiago of Chile).

INTRODUCTION: Women represent 15% of the people living with HIV in Chile. Risk behaviors for HIV are: multiple partners, unsafe sex, and exchange of sex for drugs/money. METHODOLOGY: A correlational design was used. A sample of 203 women who were sexually active and consumed substances within the last 3-months were selected for this study. RESULTS: The average age of the participants was 32.4 years (SD = 9.2) and 68.1% were housewives. The substance most commonly used was alcohol (95.1%) and marijuana (49.8%); 23.7% of the women were drunk or drugged before having sex; 74.4% had multiple sexual partners and 95.6% had unprotected sex. There is a significant correlation (p < 0.05) between substance abuse and HIV risk behaviors. CONCLUSION: It is necessary to develop more research to understand in depth the relationship between substance use and HIV risk among Chilean women. It is important to consider the use of substances to develop and implement HIV prevention programs in the Chilean community.

OBJECTIVE: Contribute the empowerment of female heads of household belonging to a community of an economically vulnerable sector of the city of Santiago, through the delivery of tools and skills in health. Sample: 13 women, between 22 and 55 years old. METHODOLOGY: Educational intervention based on the "Community as a Partner" Model of Anderson and McFarlane of Nursing and the Adult Education Model of Jane Vella. A survey was answered anonymously to collect information. The participatory diagnosis allowed identifications of thetopics concerned including: control of vital signs and its applications and first aid attention demonstrated practically in the sessions. RESULTS: Contributions were made to the knowledge regarding the management of basic care in health (Vital Signs, First Aid and Habits of Healthy Living) applied to self-care of patients and their respective families. In a simulated scenario, participants in the survey demonstrated that they practiced what they had learned. CONCLUSION: Strengths such as motivation for learning and positive response to participative methodologies were identified. Additionally, the intervention contributed to the empowerment of the participants through the learning of contents and development of confidence to confront emergency situations in every day life.

Peer group intervention for HIV prevention among health workers in Chile.

We tested the impacts of a professionally assisted peer-group intervention on Chilean health workers' HIV-related knowledge, attitudes, and behaviors using a quasi-experimental design with a pretest and 3-month posttest. Two Santiago suburbs were randomly assigned to the intervention or delayed intervention control condition. Five community clinics per suburb participated. Interested workers at the intervention (n = 262) and control (n = 293) clinics participated and completed both evaluations. At posttest, intervention clinic workers had higher knowledge and more positive attitudes regarding HIV, condoms, stigmatization, and self-efficacy for prevention. They reported more partner discussion about safer sex, less unprotected sex, and more involvement in HIV prevention activities in the clinic and the community, but they did not report fewer sexual partners or more standard precautions behaviors. Because of these positive impacts, the program will become a regular continuing education unit that can be used to meet health-worker licensing requirements.

Stigma Related to HIV among Community Health Workers in Chile.

PURPOSE: When healthcare workers have stigmatizing attitudes toward people living with HIV it may lead to discriminatory behavior that interferes with prevention, treatment, and care. This research examined the HIV-related stigmatizing attitudes reported by health workers in Santiago, Chile. METHODS: The study used focus group data from the first phase of a larger study to develop and test a HIV prevention intervention for Chilean health workers. Ten focus groups were conducted with Health workers in two communities in Santiago, Chile. Content analysis was used to analyze the data. RESULTS: Two central themes emerged: Societal stigma and discrimination towards people living with HIV and healthcare system's policies related to HIV. Both inaccurate fears of transmission among the general public and Chilean Health workers and societal prejudices against homosexuals contributed to stigmatization and discrimination. CONCLUSIONS: Health workers did not recognize their own stigmatizing attitudes or discriminatory behaviors, but their discussion indicated that these behaviors and attitudes did exist. Healthcare system issues identified included problems with confidentiality due to the desire to inform other health workers about client HIV status. Health workers must be sensitized to the current stigmatization and misinformation associated with HIV and its negative impacts on persons living with HIV and the general community. IMPLICATIONS: All clinical and non-clinical workers at community clinics need mandatory education for HIV prevention that focuses on changing attitudes as well as sharing knowledge. Also, the Chilean law protecting people living with HIV and the confidentiality of their medical care needs to be publicized, along with guidelines for its enactment in clinics and other health facilities.

Predictors of readiness for oral rapid HIV testing by Chilean health care providers / Factores predictivos de la disposición de los prestadores de atención de salud de Chile a realizar la prueba oral rápida de detección del VIH

ABSTRACT Objective This study identified the personal characteristics that affect Chilean health care providers’ readiness to adopt HIV Oral Rapid Testing (ORT) in Chile as a new clinical evidence-based practice (EBP). Methods Using a cross-sectional research design, the study sampled 150 nurses, midwives, and physicians employed at four clinics within the Pontifícia Universidad Católica de Chile Health Network in Santiago. Participants completed a self-administered survey asking about their demographic background, EBP attitudes and experience, personal beliefs related to HIV, the importance of HIV testing, and perceived self-comfort in performing a rapid HIV test. Results Of the participants, 90% believed that incorporating ORT would make a positive difference in their practice and said that they would be willing to adopt the technology for that reason. Nonetheless, the providers reported a mean “readiness to implement ORT” score of 15.1 out of a possible value of 20, suggesting only moderate self-perceived readiness to adopt the EBP. Education, beliefs about evidence-based practice, perceived comfort in performing ORT, and perceived importance of HIV testing explained 43.6% of the variance in readiness to adopt ORT. Conclusion The findings of this first ORT pre-implementation study in Chile can help guide policy makers and HIV stakeholders to prepare for and increase primary health care providers’ readiness to successfully adopt this evidence-based technology. Successful adoption of ORT could increase Chile’s capacity to reach HIV-vulnerable Chileans for testing and referral to care if infected, thus helping the country to reduce further transmission of the virus and its medical complications.

RESUMEN Objetivo En este estudio se determinaron las características personales que influyen sobre la disposición de los prestadores de atención de salud a adoptar la prueba oral rápida de detección del VIH en Chile como una nueva práctica clínica basada en la evidencia. Métodos Con un diseño de investigación transversal, en el estudio se realizó un muestreo de 150 enfermeros, parteras y médicos que trabajaban en cuatro centros de la Red de Salud de la Pontifícia Universidad Católica de Chile, en Santiago. Los participantes llenaron una encuesta autoadministrada en la que se preguntaba sus características demográficas, actitudes y experiencia en relación con la práctica clínica basada en la evidencia, creencias personales respecto del VIH, importancia de las pruebas de detección del VIH y sensación de comodidad respecto de realizar una prueba oral rápida de detección del VIH. Resultados El 90% de los participantes afirmó que creía que la incorporación de la prueba oral rápida significaría un cambio positivo en su práctica y que estaría dispuesto a adoptar la nueva tecnología por ese motivo. No obstante, de acuerdo con las respuestas, la "disposición a utilizar la prueba oral rápida" obtuvo una media de puntuación de 15,1 de un posible valor de 20, lo que sugiere solo una disposición autopercibida moderada a adoptar esta práctica basada en la evidencia. La educación, las creencias acerca de la práctica basada en la evidencia, la sensación de comodidad al realizar la prueba oral rápida y la percepción de la importancia de las pruebas de detección del VIH explican el 43,6% de la varianza de la disposición a adoptar la prueba oral rápida. Conclusiones Los resultados de este estudio previo a la introducción de la prueba oral rápida de detección del VIH en Chile pueden ser útiles para orientar a los responsables de las políticas y a las partes interesadas en cuanto a la preparación de los prestadores de atención primaria de la salud para que aumente su disposición a adoptar con éxito esta tecnología basada en la evidencia. La adopción satisfactoria de la prueba oral rápida podría aumentar la capacidad de Chile para llegar a los chilenos vulnerables a la infección por el VIH para que se realicen la prueba y sean derivados para recibir atención si tienen un resultado positivo y, de este modo, podría contribuir a detener la transmisión del virus y reducir las complicaciones médicas.

OBJETIVO: Comparar la sensibilidad y la especificidad de una prueba oral rápida con las del análisis de inmunoadsorción enzimática (ELISA) para la detección del VIH en Santiago de Chile, Chile; hacer un seguimiento del número de participantes en el estudio que regresan para saber los resultados del ELISA; y analizar las percepciones de los participantes con relación a la prueba oral rápida en comparación con el ELISA. MÉTODOS: Se incluyeron 497 personas en Santiago de Chile: 153 tenían resultados positivos para el VIH, y la situación de las restantes 344 era desconocida. Se sometió a los participantes a pruebas de detección del VIH tanto mediante el ELISA como mediante la prueba oral rápida, con objeto de analizar y comparar la especificidad y la sensibilidad. Se recopilaron datos cualitativos de 22 participantes para comparar sus impresiones con relación a la experiencia de someterse a la prueba oral rápida en comparación con el ELISA. RESULTADOS: Mediante el ELISA se notificó que 184 de los 497 participantes (37%) obtuvieron un resultado "positivo" en las pruebas de detección de anticuerpos contra el VIH; mediante la prueba oral rápida 181 participantes (36,4%) fueron "reactivos" para el VIH. Esta prueba demostró una sensibilidad de 98,4% (intervalo de confianza de 95%: 95,7-99,9%) y una especificidad de 100%. El coeficiente kappa (K) fue de 0,983 (P < 0,0001). De los 344 participantes cuyo estado con respecto a la infección por el VIH era desconocido al comienzo del estudio, 55 no regresaron para conocer los resultados del ELISA. Los participantes percibieron positivamente la prueba oral rápida debido al período de espera más breve y la reducción de la ansiedad por conocer los resultados de la prueba. La obtención de una muestra oral mediante hisopo resultó más práctica y menos invasora que la extracción de sangre necesaria para llevar a cabo un ELISA. CONCLUSIONES: La prueba oral rápida y el ELISA se mostraron estadísticamente equivalentes en cuanto a especificidad y sensibilidad. La primera proporciona resultados más rápidos, garantiza que más personas puedan conocerlos, y no requiere el manejo o la exposición a hemoderivados potencialmente peligrosos. Número de ensayo: Identificador de ClinicalTrials.gov, NCT01733927.
