Access, use and perceptions regarding Internet, cell phones and PDAs as a means for health promotion for people living with HIV in Peru

Abstract

Background

Internet tools, cell phones, and other information and communication technologies are being used by HIV-positive people on their own initiative. Little is known about the perceptions of HIV-positive people towards these technologies in Peru. The purpose of this paper is to report on perceptions towards use of information and communication technologies as a means to support antiretroviral medication adherence and HIV transmission risk reduction.

Methods

We conducted a qualitative study (in-depth interviews) among adult people living with HIV in two community-based clinics in Peru.

Results

31 HIV-positive individuals in Lima were interviewed (n = 28 men, 3 women). People living with HIV in Peru are using tools such as cell phones, and the Internet (via E-mail, chat, list-serves) to support their HIV care and to make social and sexual connections. In general, they have positive perceptions about using the Internet, cell phones and PDAs for HIV health promotion interventions.

Conclusion

Health promotion interventions using information and communication technology tools among people living with HIV in resource-constrained settings may be acceptable and feasible, and can build on existing patterns of use.

Background

The Peruvian HIV epidemic has largely has been concentrated among men who have sex with men (MSM) and female sex workers (FSW) [1,2]. The seroprevalence rate for MSM is 10–22% [2-4], compared to 0.1–0.4% for the general population [5]. The seroprevalence rate for FSW is 1% [6]. Innovative approaches are needed to enhance adherence to highly active antiretroviral treatment (ART) and to support HIV transmission risk reduction for people with HIV/AIDS. High (ideally > 95%) and sustained adherence to ART is necessary to avoid development of viral resistance. However, average ART adherence among initial cohorts of HIV-positive individuals in some resource constrained settings is only 77% [95% CI 68–85%], as noted in a recent meta-analysis of 27 African studies, and is even lower in resource-rich settings such as the US [7]. In many individuals ART adherence declines over time, and ongoing support is needed. Secondary HIV transmission prevention (i.e., from HIV-positive to HIV-negative individuals) has been under-utilized [8], and evidence-based 'prevention with positives' counseling models [9] have not yet been published in many resource-constrained settings [10,11].

World Wide Web tools [12], personal digital assistants (PDAs) [13], and cell phones [14] have been or are currently being investigated to promote HIV disease self-management. Persons in Peru who are living with, and at risk for, HIV infection also are using these technologies on their own initiative [15]. In Peru, sales of cell phones has jumped from 2.9 million in mid-2003 to 9.8 million by May 2007 [16]. Peru has one of the highest number of Internet users in public places. By January 2006, there were an estimated 10 million Internet users in Peru [15].

Boberg et al [17] suggested that people living with HIV/AIDS have specific needs including contact with other people living with HIV/AIDS, access to social supports to aid decisions around treatment, and access to information about various social services available. Reeves [18] found that the impact of Internet use on coping ability involved three themes: the Internet promotes empowerment, augments social support, and facilitates helping others.

We found no previous published reports on the perceptions among people living with HIV towards information and communication technologies in Peru. The objective of this paper is to report on information and communication technology access, use, and perceptions as a means for health promotion to support treatment adherence and HIV transmission risk reduction among people living with HIV in Peru.

Methods

We conducted formative research to assess perceptions towards information and communication technologies to support ART adherence and safer sex behaviors. This was done using in-depth interviews with adult HIV-positive people receiving ART and clinical services at two community-based clinics (Impacta, and Via Libre) in Lima, Peru. Both of these clinics primarily serve male clients (100% at Impacta, approximately 80% at Via Libre).

A qualitative interview topic guide was developed based on a published article by Flicker et al. [19], and an instrument previously used among HIV-positive individuals [20]. HIV consultants in Lima reviewed the guide in order to determine its face validity and cultural relevance. Topics covered in the guide pertaining specifically to information and communication technologies are described as follow:

Computers

How do adult HIV-positive people use computers?

• Do you ever use computers? What for? Frequency?

Internet

How do adult HIV-positive people use the Internet?

• Do you ever use the Internet? What for?

• Do you know about any sites out there for people living with HIV? Do you use them? For what?

• Where do you access these?

• Do you ever use E-mail? Chat? E-groups? Online support groups? Forums? Blogs? Advantages/Disadvantages? Which ones do you prefer?

Cell phones

How do adult HIV-positive people use cell phones?

• Do you ever use cell phones? What for? Frequency?

• Do you ever text messaging (Send/receive)?

• Do you ever use the alarm function of your cell phone? Are you currently? For what?

• If we were going to develop an application for people living with HIV in Peru using cell phones – what sort of things do you would like to see? e.g., automatic reminders, prevention messages. Any preference of using your own cell phone? or a new one?

PDAs

• If we were going to develop an application for people living with HIV in Peru using PDAs (handhelds/minicomputers, what sort of things should we be sure to include? (What content/information would you like to see on the PDA? e.g., info on medications.

• Which type of technology device do you want to use to discuss your HIV health needs? Why? How about confidentiality?

• What sort of things should we include? e.g., counselors, chat with peers.

Inclusion criteria were HIV-positive persons, older than 18 years and receiving ART. Sampling was performed by convenience in two clinics. Participants were demographically similar to those receiving care in both clinics.

Respondents spent approximately one hour for the in-depth interview conducted by an experienced and trained psychologist in each of the clinics (Impacta and Via Libre). After giving consent, all interviews were conducted in Spanish in a private room, and were tape-recorded. Audio files were transcribed and transcripts were reviewed by a Spanish-speaking investigator (WC) for initial text element and key word coding; these codes and categorizations were then reviewed by a second investigator (AK) for final consensus. Data were entered into Atlas.ti qualitative software for theme identification using a content analysis approach [21]. This analysis was intended to understand the information needs, motivations, and behaviors of people living with HIV on ART in Lima [22].

This project and the topic guide used in this study had ethical approval from the University of Washington Human Subjects Division and the institutional review boards of Via Libre and Impacta. All participants signed an informed consent prior to enter to the study. Participants were compensated with 30 soles (about 10 dollars) for travel expenses.

Results

During March–August 2006, 31 people living with HIV were interviewed, 16 at Via Libre Clinic and 15 at Impacta Clinic. Table Table11 provides representative demographic characteristics of HIV positive persons.

Findings regarding specific information and communication technologies are reviewed below.

Internet

Table Table22 provides representative verbatim quotes from individuals regarding the perceived advantages and disadvantages of Internet use, for HIV information seeking. For some people, information from the Internet can be overwhelming and may need to be discussed with knowledgeable providers; nonetheless many participants said it was a very important information source for them. A few people 3/31 (10%) reported that they found discussion groups to be useful, as a way to connect with others.

Table 2
Representative quotes from people living with HIV regarding the Internet

Two participants (6%), both of them MSM, indicated that they use or have used the Internet to see sexual partners. As one 35-year-old man said, "I use the Internet, look, to contact friends. If I wanna meet somebody I go to [name of gay chat rooms]. I contacted people for having sex." Another 43-year-old said, "I heard about people that enter to chatrooms to have sex, a lot. I think 99% of people that do that is to look for sexual contacts. I used to do that, before I was diagnosed with HIV".

In general, participants had positive experiences with the Internet regarding finding HIV treatment information. Some people had negative experiences regarding the Internet being overwhelming, being a potential source of misinformation and thus being a waste of time and money.

Cell phones

Table Table33 provides representative verbatim quotes from individuals regarding the perceived advantages and disadvantages of cell phones. Of 31 people interviewed and currently taking ART, 24 (77%) were using cell phones at the time of the interview. Some of these, 7/31 (23%), already were using the alarms on their cell phones to remind themselves to take their HIV medication. Two participants (6%) reported using their cell phones to send and receive text messages for connecting with others for social and for sexual purposes.

Table 3
Representative quotes from people living with HIV regarding cell phones

Most of those interviewed, 23/31 (74%), reported their willingness to use cell phones to receive reminder messages for their HIV medication, either by a pre-recorded voice 17/23 (74% of those willing) or by use of short-text messaging, 17/23 (74% of those willing). Not everyone felt the sustained need for using alarm reminders, after learning how to integrate medication-taking into their lives, but saw that this might be useful for ART-naïve patients particularly.

The majority, 25/31 (81%), expressed their interest in receiving messages about their sexual health over the phone, including information about sexually transmitted infections (STIs). Of those, 22/25 (88%) would prefer sexual health messages via text-messaging and 17/25 (68%) via calls with a pre-recorded voice. Furthermore, many said they would like to receive general HIV information via cell phones, including advances in HIV treatment and recent research ("Everything on STDs and HIV/AIDS"). Participants underscored the need for up-to-date information.

In general, people perceived that cell phones were confidential, though some voiced concerns about privacy. Most people said they would prefer to use their own cell phones rather than a new one that might be provided by a research study or a health agency.

Personal Digital Assistants (PDA)

None of the participants have used a PDA before. The majority, 22/31 (71%), reported that using a PDA might be very good and 8/31 (26%) people reported that using a PDA might be good as a mean for health promotion. The majority, 27/31 (87%) are willing to use a PDA.

Perceptions of advantages were: to provide information (18/31), as a reminder (10/31), to communicate with a doctor (3/31), being confidential (1/31), as a counseling tool (1/31) and to interact with other people (1/31).

Perceptions of disadvantages were: being lost/stolen (5/31), lack of privacy/confidentiality ("somebody might find the PDA in your purse, so it might identify you as HIV positive") (5/31), cost issues (4/31), lack of training or getting familiar with the PDA (3/31), battery issues (2/31), access issues ("you need to come to the clinic to interact with the PDA (2/31) and size issues ("it's big compared with cell phones") (1/31).

Discussion

Many individuals living with HIV in Peru already use or are open to using the Internet, cell phones, and personal digital assistants that might support intervention delivery for HIV treatment adherence and prevention of secondary HIV transmission (i.e., from HIV positive to HIV-negative partners). Clear advantages were seen to using these devices, among them greater confidentiality as compared to face-to-face interactions (which was mentioned as a plus by 7 out of 30 participants, as opposed to 3/30 who raised concerns about privacy related to use of these tools). In a similar resource-constrained setting, Simoes et al., reported that audio computer-assisted self-interview (ACASI) was perceived as providing the best protection of privacy of participants as compared with interviewer-administered questionnaires [23,24].

Our study population perceived that HIV information is important to their health. Similar results were found in HIV-positive African American and Puerto Rican men who felt that HIV information is vital to their health yet is not readily available in minority communities [25]. In Peru, Internet access is widely available through public centers such as Internet cafes (cabinas publicas) – small-scale storefront operations that offer low-cost and reliable connections [15]. We identified one Internet user among the 31 interviewed who didn't want to look for information on the Internet. He found the Internet to be cumbersome with too much, and potentially harmful, information (the patient reported feeling "psycho" when reading the adverse events of the medicine). This characteristic was previously reported by Hogan et al [26]. They surveyed 662 HIV people and found that 31% of people living with HIV agreed that at times it was better not to seek information. In the same survey, Hogan et al. reported that 71% of respondents agreed or strongly agreed that it was easy to feel overwhelmed by HIV information [26].

In general though, our study found that people found useful information on the Internet. Other researchers have reported that people living with HIV who use the Internet for health care indicated that they experienced improved knowledge about the illness, increased skills in coping, and support from others [27]. For example, the anonymity provided by online groups allows discussion of potentially embarrassing topics or otherwise taboo; thus use of online groups increases the possibilities for self-disclosure and encourages honesty and intimacy.

There is great potential to improve health through the use of information and communication technologies in developing countries. The problems of low Internet diffusion and the digital divide are obstacles that resource-constrained countries face in using the Internet for health and development purposes. For those having access the Internet, searching for health information on the Internet can be a difficult experience. Literacy issues might be a problem, as many web pages are written in (often, English-language) text. People may find searching to be time consuming and difficult, and, most frustrating, information may not be in their language. For these reasons, use of scarce resources for information and communication technologies may not necessarily be seen as relevant or appropriate in all settings.

There are some organizations in Peru that offer sexual information via the Internet, suggesting that a user audience is present for information technology-delivered sexual health information. For example, the Peruvian Institute for Responsible Parenthood (INPPARES) has incorporated the Internet into its national sexuality information and counseling service. INPPARES provides information on contraceptive methods, STIs, HIV/AIDS, pregnancy, etc [28]. Academic institutions such as the Universidad Peruana Cayetano Heredia (UPCH) have developed several websites. For example, the RED PREVEN website [29] offers prevention information on HIV/STIs as well as a forum for frequent asked questions. Impulsa SIDA is a project of the Tropical Medicine Institute "Alexander von Humboldt" – UPCH [30] that offers prevention information on HIV/STIs as well as information for people with HIV and their families. Unfortunately, those links did not come up during the interviews. Expansion of Internet and other technologies for partner notification [31], HIV/STI risk reduction, and related sexual health approaches seems opportune. For example, in the recent years, technologies such as cell phones, Internet, email and text messaging have been adopted for partner notification [32]. In the first study addressing the use of the Internet for online partner notification, participants of an Internet chat room were notified via e-mail messages about a syphilis cluster and encouraged to seek medical evaluation. As a result 42% of named partners were notified and tested [33].

There are some limitations of the study. The current study was limited by its use of a convenience sample of people living with HIV/AIDS in an urban population of Lima. The participants in this study cannot be considered representative of people living with HIV/AIDS in Peru. We also assessed Internet use, cell-phone use and PDA use by self-report.

Finally, this is the first study to our knowledge that examined perceptions regarding Internet, cell phones and PDAs as a means for health promotion for people living with HIV in Peru. Therefore all of the study findings require replication.

Conclusion

This qualitative study suggested that cell phones in particular may be useful and culturally-relevant as a way to support medication adherence and HIV transmission risk reduction among persons living with HIV in Lima. Participants showed enthusiasm for the potential impact of cell phones interventions using voice-recorded reminders and SMS texting as a way to deliver behavioral messages, and most participants expressed interest in participating in such an intervention. Other advantages of cell-phone delivered behavioral support include the fact that in many resource-constrained settings, cell phone communication infrastructure already is in place at a population-level scale, and thus would not need to be built separately to support persons with HIV (or potentially, other chronic diseases). Based on these pilot data, our team is now developing the framework for a cell-phone and a PDA delivered HIV intervention in Lima. The qualitative data we report here can help researchers decide which user-centered information and communication technology devices may be useful to people living with HIV/AIDS in resource-constrained settings.
