Quality of counselling and support provided by the South African National AIDS Helpline: Content analysis of mystery client interviews.

BACKGROUND: Telephone helplines can facilitate referral, education and support for patients living with HIV or those concerned about the infection. The anonymity of helplines facilitates discussion of sensitive issues that are difficult to raise face to face. These services could support the expansion of HIV self-testing. However, maintaining quality and standardising messages in rapidly evolving fields such as HIV is challenging. OBJECTIVES: To evaluate the quality of the South African (SA) National AIDS Helpline. METHODS: Mystery clients posing as members of the public made 200 calls to the service in 2014. They presented several scenarios, including having received HIV-positive results from a doctor's secretary or through self-testing. Following the call, 'clients' completed a semistructured questionnaire on the information received and the caller-counsellor interaction. RESULTS: Calls were answered within a median of 5 seconds (interquartile range 2 - 14). Conversations took place in 8 of the 11 SA official languages, though mainly in English. Overall, 75% of callers felt that with the information they received they could locate a nearby clinic for further services. Counsellors expressed appropriate levels of concern about inadequate counselling that callers had received and confidentiality breaches in some scenarios. Eight counsellors incorrectly mentioned the need for a waiting period to confirm a positive result. Consistent with policy, almost all said that being foreign would not affect HIV treatment access. About 90% explained the need for CD4+ testing and antiretroviral therapy, but only 78% discussed HIV prevention. Counsellors were mostly empathetic (83%), though some adopted a neutral tone (10%) or were brusque (6%) or unhelpful (2%). CONCLUSIONS: Overall, helpline counsellors were proficient at providing information about local clinics, HIV testing and steps needed for initiating ART. Dissatisfaction with the caller-counsellor interactions, instances of incorrect information and the relatively low attention accorded to HIV prevention are worrying, however. Training for both refreshing and updating knowledge, and supervision and monitoring of calls, could target these areas.

Age-associated changes in obstacle negotiation strategies: Does size and timing matter?

INTRODUCTION: Tripping over an obstacle is one of the most common causes of falls among older adults. However, the effects of aging, obstacle height and anticipation time on negotiation strategies have not been systematically evaluated. METHODS: Twenty older adults (ages: 77.7±3.4years; 50% women) and twenty young adults (age: 29.3±3.8years; 50% women) walked through an obstacle course while negotiating anticipated and unanticipated obstacles at heights of 25mm and 75mm. Kinect cameras captured the: (1) distance of the subject's trailing foot before the obstacles, (2) distance of the leading foot after the obstacles, (3) clearance of the leading foot above the obstacles, and (4) clearance of the trailing foot above the obstacles. Linear-mix models assessed changes between groups and conditions. RESULTS: Older adults placed their leading foot closer to the obstacle after landing, compared to young adults (p<0.001). This pattern was enhanced in high obstacles (group*height interaction, p=0.033). Older adults had lower clearance over the obstacles, compared to young adults (p=0.007). This was more pronounced during unanticipated obstacles (group*ART interaction, p=0.003). The distance of the leading foot and clearance of the trailing foot after the obstacles were correlated with motor, cognitive, and functional abilities. CONCLUSIONS: These findings suggest that there are age-related changes in obstacle crossing strategies that are dependent on the specific characteristics of the obstacle. The results have important implications for clinical practice, suggesting that functional exercise should include obstacle negotiation training with variable practice of height and available response times. Further studies are needed to better understand the effects of motor and cognitive abilities.

Community perspective on the INSIGHT Strategic Timing of AntiRetroviral Treatment (START) trial.

Determining when to start antiretroviral treatment (ART) is vitally important for people living with HIV. Yet the optimal point at which to start to maximize clinical benefit remains unknown. In the absence of randomized studies, current guidelines rely on conflicting observational data and expert opinion, and consequently diverge on this point. In the USA, ART is recommended irrespective of CD4 cell count. The World Health Organization now recommends starting ART at a CD4 cell count of 500 cells/µL, while the threshold for the UK and South Africa remains at 350 cells/µL. The Strategic Timing of AntiRetroviral Treatment (START) study, one of the largest clinical trials on the treatment of HIV infection, will answer this question. START compares two treatment strategies: immediate treatment at a CD4 cell count of 500 cells/µL or higher versus deferring treatment until the CD4 cell count decreases to 350 cells/µL or until AIDS develops. START includes seven substudies, five of which will clarify the relative contributions of HIV and ART in common comorbidities. START is fully enrolled and expected to be completed in 2016. HIV advocates support the study's design and have been involved from inception to enrolment. The trial will produce rigorous data on the benefits and risks of earlier treatment. It will inform policy and treatment advocacy globally, benefitting the health of HIV-positive people.
