Feasibility and Effectiveness of Provider Initiated HIV Testing and Counseling of TB Suspects in Vizianagaram District, South India

BackgroundThough internationally recommended, provider initiated HIV testing and counseling (PITC) of persons suspected of tuberculosis (TB) is not a policy in India; HIV seroprevalence among TB suspects has never been reported. The current policy of PITC for diagnosed TB cases may limit opportunities of early HIV diagnosis and treatment. We determined HIV seroprevalence among persons suspected of TB and assessed feasibility and effectiveness of PITC implementation at this earlier stage in the TB diagnostic pathway.MethodsAll adults examined for diagnostic sputum microscopy (TB suspects) in Vizianagaram district (population 2.5 million), in November-December 2010, were offered voluntary HIV counseling and testing (VCT) and assessed for TB diagnosis.ResultsOf 2918 eligible TB suspects, 2465(85%) consented to VCT. Among these, 246(10%) were HIV-positive. Of the 246, 84(34%) were newly diagnosed as HIV (HIV status not known previously). To detect a new case of HIV infection, the number needed to screen (NNS) was 26 among ‘TB suspects’, comparable to that among ‘TB patients’. Among suspects aged 25–54 years, not diagnosed as TB, the NNS was 17.ConclusionThe seroprevalence of HIV among ‘TB suspects’ was as high as that among ‘TB patients’. Implementation of PITC among TB suspects was feasible and effective, detecting a large number of new HIV cases with minimal additional workload on staff of HIV testing centre. HIV testing of TB suspects aged 25–54 years demonstrated higher yield for a given effort, and should be considered by policy makers at least in settings with high HIV prevalence.

Provider-Initiated HIV Testing and Counseling in Low- and Middle-Income Countries: A Systematic Review

Provider-initiated HIV testing and counseling (PITC) has expanded since 2007 WHO guidelines were established. We conducted a systematic review of PITC in low- and middle-income countries. Peer-reviewed studies were included if they measured pre-post or multi-arm outcomes. Two coders abstracted data using standardized forms. Nineteen studies were included, all from sub-Saharan Africa (N = 15) or Asia (N = 4). Studies were conducted in clinics for antenatal/family planning/child health (N = 12), tuberculosis (N = 4), outpatient (N = 1), sexually transmitted diseases (N = 1), and methadone maintenance (N = 1). HIV testing uptake increased after PITC. Condom use also increased following PITC in most studies; nevirapine uptake and other outcomes were mixed. Few negative outcomes were identified. Findings support PITC as an important intervention to increase HIV testing. PITC's impact on other outcomes is mixed, but does not appear to be worse than voluntary counseling and testing. PITC should continue to be expanded and rigorously evaluated across settings and outcomes.

An analysis on PITC pilot in maternal and child care service centre

Objective To evaluate the feasibility of the provider initiated HIV testing and counseling (PITC) pilot in maternal and child care service centre and to find out problems and solutions in implementing PITC, so as to provide evidence for making strategies and policies for acquired immune deficiency syndrome (AIDS) control and prevention.Methods The Maternal and Children Health Care Service Centre of Panyu District in Guangzhou was selected as a clinical trial of medical institution,3 outpatient departments for the pilot were chosen,pilot work report and interview results and other information were collected for analysis.Results During the project cycle, 57,309 provider-initiated HIV tests were recommended, and 19,809 (34.57％) were accepted.The number of HIV testing rates in premarital check-up,obstetrics and gynecology clients were 9,817(100.00％),6,157(35.63％) and 3,569(12.37％)respectively.The HIV testing rates of obstetric were higher than those of gynecological,there were significant differences (x2 =3514.723,P＜ 0.01).19,809 people accepted test,3 persons confirmed HIV-positive (0.15％).The main cause of rejecting HIV testing of the patients in obstetrical and gynecological was think they have no possibility of HIV infection, with proportion of 41％ and 59％ respectively.Obstetrics and gynecology HIV testing rates were compared to those 15 months before,there were significant differences (P ＜ 0.01).ConcIusions It is feasible to implement PITC in maternal and child care service centre,policy support and testing fee are key factors that influence the implementation of PITC.

HIV/STD pattern and its associated risk factors among male STD clinic attendees in China: a foci for HIV intervention

BackgroundPrevious studies suggested a high prevalence of STDs including HIV among female sex workers and men who have sex with men in China, but little was known about the prevalence in male patients attending public STD clinics. The aim of this study was to investigate STD patterns and HIV prevalence among male STD clinic attendees in different areas in China and the associated risk factors. The feasibility of Provider-initiated HIV testing and counseling (PITC) was evaluated as well.MethodsA cross-sectional study was conducted at 46 public STD clinics in 4 provinces in China. Between July 2009 and September 2009, a total of 3243 eligible subjects were invited to participate in an interview with a structured-questionnaire for collecting socio-demographic characteristics and sexual behavioral information. They also were asked to provide venous blood samples for serological determinations of HIV and syphilis infection, and first void urine specimens for detecting Chlamydia trachomatis and Neisseria gonorrhoeae infections,ResultsOut of the 3243 eligible patients, 2951(91%) men agreed to take part in the HIV and syphilis testing. The overall prevalence rate of HIV infection was 0.7% while the rates of syphilis, N. gonorrhoeae, C. trachomatis infections were 10.7%, 4.3% and 6.9%, respectively, with the highest syphilis and N. gonorrhoeae rates in Jiangsu Province. Patients from Guangxi province, homosexual/bisexual practices and intravenous drug use were significantly associated with HIV infection in multivariate logistic regression analyses. Provider-initiated HIV testing and counseling (PITC) was well accepted by attendees, with 91% of eligible attendees agreeing to undergo HIV testing and counseling. All HIV positive patients were properly managed accordingly.ConclusionsA modest prevalence of HIV infection and substantial prevalence of other STD infections were found among male patients attending public STD clinics in China. The findings further support the introduction of HIV and syphilis PITC strategy into this important setting.

Provider-Initiated HIV Testing and Counseling: Increased Uptake in Two Public Community Health Centers in South Africa and Implications for Scale-Up

BackgroundInternational guidance recommends the scale up of routinely recommended, offered, and delivered health care provider-initiated HIV testing and counseling (PITC) to increase the proportion of persons who know their HIV status. We compared HIV test uptake under PITC to provider-referral to voluntary counseling and testing (VCT referral) in two primary health centers in South Africa.MethodsPrior to introducing PITC, clinical providers were instructed to refer systematically selected study participants to VCT. After PITC and HIV rapid test training, providers were asked to recommend, offer and provide HIV testing to study participants during the clinical consultation. Participants were interviewed before and after their consultation to assess their HIV testing experiences.ResultsHIV test uptake increased under PITC (OR 2.85, 95% CI 1.71, 4.76), and more patients felt providers answered their questions on HIV (104/141 [74%] versus 73/118 [62%] for VCT referral; p 0.04). After three months, only 4/106 (3.8%) HIV-positive patients had registered for onsite HIV treatment. Providers found PITC useful, but tested very few patients (range 0–15).ConclusionPITC increased the uptake of HIV testing compared with referral to onsite VCT, and patients reported a positive response to PITC. However, providing universal PITC will require strong leadership to train and motivate providers, and interventions to link HIV-positive persons to HIV treatment centers.

Perception of Risk of Vertically Acquired HIV Infection and Acceptability of Provider-Initiated Testing and Counseling Among Adolescents in Zimbabwe

We investigated attitudes toward provider-initiated HIV testing and counseling (PITC) in the suburbs of Harare, Zimbabwe, where late presentation after mother-to-child HIV transmission (MTCT) is a major cause of adolescent mortality. Adolescents (10-18 years) attending 2 primary clinics were offered PITC. Participants completed a questionnaire investigating acceptability of PITC, and in-depth interviews with 41 adolescents and 30 guardians explored understanding of long-term survival after MTCT. Of 506 participants, 16 were known to be HIV-positive; of the remaining 490, only 5 (1%) declined HIV testing. Infected adolescents and their guardians often anticipated a positive result and reported being advised by relatives (but not health workers) to be tested because of chronic illness, especially if parents or siblings had died or were HIV-infected. However, HIV-negative participants were not aware that long-term survival following MTCT could occur. All adolescents felt that HIV diagnosed at their age would be assumed to have been sexually acquired regardless of the true mode of transmission. Including late diagnosis of MTCT in pretest counseling and health educational messages may facilitate PITC for older children and adolescents, especially for those who have not had their sexual debut.

A Comparison of HIV Detection Rates Using Routine Opt-out Provider-Initiated HIV Testing and Counseling Versus a Standard of Care Approach in a Rural African Setting

Routine opt-out provider-initiated HIV testing and counseling (PITC) remains underutilized in sub-Saharan Africa. By selectively targeting clients who either volunteer or have clinical indications of HIV disease, standard approaches to HIV counseling and testing are presumed more cost-efficient than PITC. One thousand two hundred twenty-one patients aged 15– 49 years were seen by 22 practitioners in a mobile clinic in southern Zambia. A random sample of physicians was assigned to administer PITC, whereas the remaining practitioners offered standard non- PITC (ie, voluntary or diagnostic). Questionnaires assessed patient demographics and attitudes toward HIV. HIV detection rates were stratified by referral type, demographics, and HIV-related knowledge and attitudes. HIV prevalence was 10.6%. Infection rates detected using PITC [11.1%; 95% confidence interval (CI): 8.8% to 13.5%] and standard non-PITC (10.0%; 95% CI: 7.5% to 12.5%) did not significantly differ (odds ratio = 1.01; 95% CI: 0.67 to 1.52; P = 0.95). Patients who did not request testing or demonstrate clinical indicators of HIV did not have significantly higher HIV prevalence than those who did (odds ratio = 0.83; 95% CI: 0.55 to 1.24; P = 0.36). Implementation of PITC was highly acceptable and produced a 3-fold increase in patients tested per practitioner compared with standard non-PITC (114 vs. 34 patients per practitioner, respectively). PITC detected a comparable HIV infection rate as a standard non-PITC approach among rural adults seeking primary care services. Widespread implementation of PITC may therefore lead to significantly more cases of HIV detected.

Prevalence and clinical pattern of paediatric HIV infection at the University College Hospital, Ibadan, Nigeria: a prospective cross-sectional study

BackgroundThe prevalence of Paediatric HIV infection is largely unknown in many countries in sub-Saharan Africa. This study was aimed at determining the prevalence, clinical pattern of HIV infection and outcome among new patients aged <15 years using age-specific diagnostic methods.MethodsA prospective cross sectional study was carried out using the provider initiated HIV testing and counselling (PITC) model. HIV rapid test in parallel was used for screening and confirmation was with HIV DNA PCR in children <18 months and Western Blot in children ≥ 18 months.ResultsA total of 600 children were enrolled with ages ranging between one day and 179 months. Male: female ratio was 1.2:1. HIV seroprevalence was 12.3% and after confirmatory tests, the prevalence was 10%. Fourteen (37.8%) of the children aged less 18 months were exposed but not infected. Mother-to-child transmission accounted for 93.3% of cases. Features predictive of HIV infection were diarrhoea, cough, weight loss, ear discharge generalized lymphadenopathy, presence of skin lesions, parotid swelling and oral thrush. About 75% presented in advanced or severe clinical stages of the disease, 56.8% had severe immunodeficiency while 50% had viral loads more than 100,000 copies/ml. Mortality rate was 14.3% among HIV positive compared with 11.3% in HIV negative children but was not significant. Among the HIV positive children, 26.7% were orphans.ConclusionsThe prevalence rate of HIV infection among new patients screened using the PITC model was high, majority resulting from mother-to-child transmission. Most children presented in advanced stages of the disease and mortality rate among them was high. Though, the study site being a referral centre might have contributed to the high prevalence observed in this study, there is a need to expand access to PMTCT services, ensure implementation of PITC in paediatric settings and expand support services for HIV infected children.

Prevalence and barriers to HIV testing among mothers at a tertiary care hospital in Phnom Penh, Cambodia. Barriers to HIV testing in Phnom Penh, Cambodia.

BackgroundOne-third of all new HIV infections in Cambodia are estimated to be due to mother-to-child transmission. Although the Ministry of Health adopted a policy of provider-initiated HIV testing and counseling (PITC), nearly a quarter of pregnant mothers were not tested in 2007. Greater acceptance of HIV testing is a challenge despite Cambodia's adoption of the PITC policy.MethodsA hospital-based quantitative and cross-sectional survey was conducted to assess the prevalence of and barriers to HIV testing among mothers after delivery at the National Maternal and Child Health Center in Phnom Penh. The Center is one of the largest maternal and child care hospitals in the country to offer PITC services. All 600 eligible mothers who were admitted to the hospital after delivery from October to December 2007 were approached and recruited. Data were collected via a semi-structured questionnaire.ResultsThe prevalence of HIV testing among women who delivered at the hospital was 76%. In multivariate logistic regression, factors such as the perceived need to obtain a partner's permission to be tested (OR=0.27, 95% CI=0.14-0.51, p<0.01), the lack of knowledge about HIV prevention and treatment (OR=0.38, CI=0.22-0.66, p<0.01), and the lack of access to ANC services (OR=0.35, 95% CI=0.21-0.58, p<0.01) were found to be the main barriers to HIV testing.ConclusionTo achieve greater acceptance of HIV testing, counseling on HIV prevention and treatment must be provided not only to mothers but also to their partners. In addition, utilization of non-laboratory staff such as midwives to provide HIV testing services in rural health facilities could lead to the greater acceptance of HIV testing.

Uptake of provider-initiated HIV testing and counseling among women attending an urban sexually transmitted disease clinic in South Africa – missed opportunities for early diagnosis of HIV infection

This study assessed the uptake of provider-initiated HIV testing and counseling (PITC) among women attending an urban sexually transmitted diseases (STD) clinic in South Africa. From July 2005 to June 2006, women were offered HIV testing following group information and education on HIV and STDs in the clinic waiting area. Of those who were provided with education, information, and offered HIV testing, uptake was 43.5% (2439/5612). The overall HIV prevalence among those tested was 56.5% and the prevalence of acute HIV infection was 1.2%. Of the 56.5% (3173/5612) refusing to test, the reasons for not testing were having already been tested for HIV (61.8%), being afraid to test or felt unready to test (32.5%), the need to consult with partner (0.9%), and refusing with no explanation (4.8%). In settings where high-risk patients await health care services, such as an STD clinic, failure to implement PITC is a missed opportunity for patients to benefit from counseling, prevention, early diagnosis, and referral into care and treatment for HIV infection.

Provider Challenges in Implementing Antenatal Provider-Initiated HIV Testing and Counseling Programs in Uganda

While provider-initiated HIV testing and counseling (PITC) programs are being increasingly implemented in antenatal care settings, there is scant information about the specific challenges providers face when offering these services. Through qualitative interviews with 30 HIV antenatal care providers from 10 clinics in central Uganda, we sought to understand specific challenges Ugandan providers face in implementing antenatal PITC programs, including how these challenges impact prevention of mother-to-child HIV transmission programs. Counseling-specific challenges included counseling discordant couples, incomplete follow-up of HIV-infected clients, low rates of both male involvement and HIV serostatus discourse, and inadequate training and support to carry out counseling duties. Health system challenges included lack of adequate space for counseling, frequent "stock-outs" of supplies, shortages of both counselors and lab personnel, and inadequate referral services. These challenges must be addressed in order to optimize the success of PITC programs at providing universal access to HIV testing and counseling services.

The impact of provider-initiated (opt-out) HIV testing and counseling of patients with sexually transmitted infection in Cape Town, South Africa: a controlled trial.

BackgroundThe effectiveness of provider-initiated HIV testing and counseling (PITC) for patients with sexually transmitted infection (STI) in resource-constrained settings are of particular concern for high HIV prevalence countries like South Africa. This study evaluated whether the PITC approach increased HIV testing amongst patients with a new episode of sexually transmitted infection, as compared to standard voluntary counseling and testing (VCT) at the primary care level in South Africa, a high prevalence and low resource setting.MethodsThe design was a pragmatic cluster-controlled trial with seven intervention and 14 control clinics in Cape Town. Nurses in intervention clinics integrated PITC into standard HIV care with few additional resources, whilst lay counselors continued with the VCT approach in control clinics. Routine data were collected for a six-month period following the intervention in 2007, on new STI patients who were offered and who accepted HIV testing. The main outcome measure was the proportion of new STI patients tested for HIV, with secondary outcomes being the proportions who were offered and who declined the HIV test.ResultsA significantly higher proportion of new STI patients in the intervention group tested for HIV as compared to the control group with (56.4% intervention versus 42.6% control, p = 0.037). This increase was achieved despite a significantly higher proportion intervention group declining testing when offered (26.7% intervention versus 13.5% control, p = 0.0086). Patients were more likely to be offered HIV testing in intervention clinics, where providers offered the HIV test to 76.8% of new STI patients versus 50.9% in the control group (p = 0.0029). There was significantly less variation in the main outcomes across the intervention clinics, suggesting that the intervention also facilitated more consistent performance.ConclusionsPITC was successful in three ways: it increased the proportion of new STI patients tested for HIV; it increased the proportion of new STI patients offered HIV testing; and it delivered more consistent performance across clinics. Recommendations are made for increasing the impact and feasibility of PITC in high HIV prevalence and resource-constrained settings. These include more flexible use of clinical and lay staff, and combining PITC with VCT and other community-based approaches to HIV testing.Trial registrationControlled trial ISRCTN93692532

Perceptions of Tuberculosis Patients on Provider-Initiated HIV Testing and Counseling - A Study from South India

BackgroundThe acceptability and feasibility of provider-initiated HIV testing and counseling (PITC) in many settings across Asia with concentrated HIV epidemics is not known. A pilot study of the PITC policy undertaken within the public health care systems in two districts in India offered the opportunity to understand patient's perspectives on the process of referral for HIV testing and linking to HIV treatment and care.MethodsWe conducted a cross-sectional study of randomly selected TB patients registered by the TB control program between July and November 2007 in two districts in south India. Trained interviewers met patients shortly after TB diagnosis and administered a structured questionnaire. Patients were assessed regarding their experience with HIV status assessment, referral for counseling and testing, and for HIV-infected patients the counseling itself and subsequent referral for HIV treatment and care.ResultsOf the 568 interviewed TB patients, 455 (80%) reported being referred for HIV testing after they presented to the health facility for investigations or treatment for TB. Over half the respondents reported having to travel long distances and incurred financial difficulties in reaching the Integrated Counselling and Testing Centre (ICTC) and two-thirds had to make more than two visits. Only 48% reported having been counseled before the test. Of the 110 HIV-infected patients interviewed, (including 43 with previously-known positive HIV status and 67 detected by PITC), 89 (81%) reported being referred for anti-retroviral treatment (ART); 82 patients reached the ART centre but only 44 had been initiated on ART.ConclusionsThis study provides the first evidence from India that routine, provider-initiated voluntary HIV testing of TB patients is acceptable, feasible and can be achieved with very high efficiency under programmatic conditions. While PITC is useful in identifying new HIV-infected patients so that they can be successfully linked to ART, the convenience and proximity of testing centres, quality of HIV counseling, and efficiency of ART services need attention.

Effect of provider-initiated testing and counselling and integration of ART services on access to HIV diagnosis and treatment for children in Lilongwe, Malawi: a pre- post comparison

BackgroundThe HIV prevalence in Malawi is 12% and Kamuzu Central Hospital (KCH), in the capital Lilongwe, is the main provider of adult and paediatric HIV services in the central region. The Lighthouse at KCH offers opt-in HIV testing and counselling (HTC) for adults and children. In June 2004, Lighthouse was the first clinic to provide free antiretroviral treatment (ART) in the public sector, but few children accessed the services. In response, provider-initiated HIV testing and counselling (PITC) and an ART clinic were introduced at the paediatric department at KCH in Quarter 4 (Q4) 2004.MethodsWe analysed prospectively collected, aggregated data of quarterly reports from Q1 2003 to Q4 2006 from HTC centre registers, ART registers and clinic registrations at the ART clinics of both Lighthouse and the paediatric department. By comparing data of both facilities before (Q1 2003 to Q3 2004), and after the introduction of the services at the paediatric department (Q4 2004 to Q4 2006), we assessed the effect of this intervention on the uptake of HIV services for children at KCH.ResultsOverall, 3971 children were tested for HIV, 2428 HIV-infected children were registered for care and 1218 started ART. Between the two periods, the median (IQR) number of children being tested, registered and starting ART per quarter rose from 101 (53-109) to 358 (318-440), 56 (50-82) to 226 (192-234) and 18 (8-23) to 139 (115-150), respectively. The median proportion of tested clients per quarter that were children rose from 3.8% (2.7-4.3) to 9.6% (8.8 to 10.0) (p = 0.0009) and the proportion of ART starters that were children rose from 6.9% (4.9-9.3) to 21.1% (19.2-24.2) (p = 0.0036). The proportion of registered children and adults starting ART each quarter increased similarly, from 26% to 53%, and 20% to 52%, respectively.ConclusionsImplementation of PITC and integration of ART services within the paediatric ward are likely to be the main reasons for improved access to HTC and ART for children at KCH, and can be recommended to other hospitals with paediatric inpatients in resource limited settings with high HIV prevalence.

Feasibility of Provider-Initiated HIV Testing and Counselling of Tuberculosis Patients Under the TB Control Programme in Two Districts of South India

BackgroundProvider-initiated HIV testing and counselling (PITC) is internationally recommended for tuberculosis (TB) patients, but the feasibility, effectiveness, and impact of this policy on the TB programme in India are unknown. We evaluated PITC of TB patients across two districts in India considered to have generalized HIV epidemics, Tiruchirappalli (population 2.5 million) and Mysore (population 2.8 million).Methodology/Principal FindingsStarting June 2007, healthcare providers in both districts were instructed to ascertain HIV status for all TB patients, and refer those with unknown HIV status to the nearest Integrated Counselling and Testing Centre (ICTC)—often in the same facility—for counselling and voluntary HIV testing. All TB patients registered from June 2007 to March 2008 were followed prospectively. Field investigators assessed PITC practices and abstracted data from routine TB programme records and HIV counselling registers to determine the proportion of TB patients appropriately evaluated for HIV infection. Patient records were traced to determine the efficiency of referral links to HIV care and antiretroviral treatment (ART). Between July 2007 and March 2008, 5299 TB patients were registered in both study districts. Of the 4701 with unknown HIV status at the time of TB treatment initiation, 3368 (72%) were referred to an ICTC, and 3111 (66%) were newly tested for HIV. PITC implementation resulted in the ascertainment of HIV status for 3709/5299 (70%) of TB patients, and detected 200 cases with previously undiagnosed HIV infection. Overall, 468 (8.8%) of all registered TB patients were HIV-infected; 177 (37%) were documented to have also received any ART.ConclusionsWith implementation of PITC in India, HIV status was successfully ascertained for 70% of TB patients. Previously undiagnosed HIV-infection was detected in 6.4% of those TB patients newly tested, enabling referral for life-saving anti-retroviral treatment. ART uptake, however, was poor, suggesting that PITC implementation should include measures to strengthen and support ART referral, evaluation, and initiation.

Barriers to HIV testing among mothers at a maternity ward in Phnom Penh, Cambodia

Introduction As a response to the shift in epidemic transmission, prevention of mother to child transmission (PMTCT) services have been expanded in Cambodia. However, the improvement of the acceptance for HIV testing and counselling is still challenging even after the ministry of health in Cambodia adopted provider-initiated HIV testing and counselling (PITC) policy. The objective of this study was to investigate the accessibility of HIV testing and its barriers among mothers at maternity ward in Phnom Penh where the PITC approach had been widely offered.

PROVIDER‐INITIATED HIV TESTING AND COUNSELING IN HEALTH FACILITIES – WHAT DOES THIS MEAN FOR THE HEALTH AND HUMAN RIGHTS OF PREGNANT WOMEN?

Since the introduction of drugs to prevent vertical transmission of HIV, the purpose of and approach to HIV testing of pregnant women has increasingly become an area of major controversy. In recent years, many strategies to increase the uptake of HIV testing have focused on offering HIV tests to women in pregnancy-related services. New global guidance issued by the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) specifically notes these services as an entry point for provider-initiated HIV testing and counseling (PITC). The guidance constitutes a useful first step towards a framework within which PITC sensitive to health, human rights and ethical concerns can be provided to pregnant women in health facilities. However, a number of issues will require further attention as implementation moves forward. It is incumbent on all those involved in the scale up of PITC to ensure that it promotes long-term connection with relevant health services and does not result simply in increased testing with no concrete benefits being accrued by the women being tested. Within health services, this will require significant attention to informed consent, pre- and post-test counseling, patient confidentiality, referrals and access to appropriate services, as well as reduction of stigma and discrimination. Beyond health services, efforts will be needed to address larger societal, legal, policy and contextual issues. The health and human rights of pregnant women must be a primary consideration in how HIV testing is implemented; they can benefit greatly from PITC but only if it is carried out appropriately.

Response to opt-out approach to prevent mother-to-child transmission of HIV

I read with great interest the paper on routine HIV testing for pregnant women in Zimbabwe by Winfreda Chandisarewa et al.1 The paper reported a significant increase in the acceptance of PMTCT (preventing mother-to-child transmission) services such as HIV testing, counselling and follow-up after the introduction of routine HIV testing (“opt-out” approach). However, the conclusion that the opt-out approach for HIV testing was operationally feasible and acceptable to all women, and that HIV-infected women reported relatively low levels of spousal abuse and other adverse social consequences, seems to be overstated. Results from a survey of the tested mothers indicated that approximately 10% of those women who disclosed their test results still experienced negative effects. These findings hardly indicate “low levels of spousal abuse and other adverse social consequences” in consideration of these women’s personal safety. It is necessary to evaluate the opt-out approach for HIV testing by comparing the incidence of adverse effects with mothers who opted-in to HIV testing to conclude whether the benefit of the opt-out approach outweighs the risk. More importantly, more attention must be paid to the issue of domestic violence by partners after disclosure, since many cases have been reported in African countries.2–4 In addition, the authors should show the percentage of those mothers who had been tested and counselled before the study period. As the majority of mothers in the study were reportedly multiparae, they might have been tested for HIV in previous pregnancies. Mothers re-tested during the study are likely to have experienced fewer negative effects. Moreover, I would like to suggest that the authors provide more information on the role of the community mobilization activities conducted before the introduction of the opt-out approach. Barriers and predictors to HIV testing have been investigated to improve the acceptance of HIV testing in PMTCT services.5,6 This research shows that community activities play an important role in clearing some of the barriers to testing and counselling services, therefore providing an entry point to prevention and care services including PMTCT. These activities, together with high-quality counsellors, might have contributed to increasing the acceptance of HIV testing and counselling and to reducing its adverse effects. The contents of the community mobilization activities, including male involvement, could be analysed more and shared with readers, so as to provide a good model to commencing provider-initiated HIV testing and counselling (PITC) in other areas. There have been a lot of arguments about human rights and HIV testing. However, I would like to stress that we need more good practices with successful increased uptake of PMTCT services and minimal negative impact, so as to provide practical ideas for the adaptation of the WHO guidelines on PITC at country level.7 The activities outlined in this study, especially those conducted in the community, could help to provide such ideas. ■
