Item Characteristics of ‘lost to follow up’ patients on antiretroviral treatment (ART) defaulting at Tshwane District Hospital(2011-11-23) Ubogu, Olufunmilayo ItunuAfter 25 years of existence, the Human Immuno-deficiency Virus (HIV) has become a global challenge. Yearly, about 3 million people in the sub Saharan region become infected with the disease each year, while 2 million die of the disease. The young, sexually active and those in the economically active group are mostly affected although other categories are also affected. Over the years efforts have been made to turn HIV infection from a death sentence to a manageable chronic disease through the use of antiretro viral treatment (ART). Despite the fact that this treatment is a life-long commitment with adherence being crucial to its effectiveness, some patients still default. This research study sought to identify the characteristics of HIV positive patients who are lost to follow up after the initiation of antiretroviral treatment over a 2-year period (2007-2008). A tick sheet was used to collect data from all the files of patients lost to follow up and 20 variables were tested. The conclusion reached is that age, sex, distance of residence to the ART site and economic capability contribute to ‘lost to follow-up’.Item An exploration of the experiences of clients on antiretroviral therapy and their health care providers in KwaZulu Natal(2011-04-07) Mhlongo, Euphemia MbaliThe aim of the study was to explore the practice of antiretroviral (ARV) therapy services, specifically regarding the patients’ issues and experiences, as well as the experiences of the health care providers rendering these services. Qualitative research methods were used, including a metasynthesis of qualitative research articles on human immunodeficiency virus (HIV) positive patients on ARV therapy, and phenomenological methods of inquiry. The study objectives were to conduct a metasynthesis of qualitative research on HIV-positive people on ARV therapy; to investigate the experiences of HIV-positive people who are on ARV therapy; to identify the constraints faced by HIV-positive people receiving ARV therapy; and to explore adherence to ARV therapy. The study was conducted in eThekwini district in KwaZulu Natal (KZN) province. The district was chosen considering the number of clinics rolling out ARV therapy. Three institutions initiating ARV therapy participated in the study; one urban, one semi-urban and one rural clinic, to ensure representation of each type. Participants were recruited from two initiating hospitals and one Community Health Centre providing ARV therapy. The metasynthesis revealed a shared set of four themes viz.: 1. Acceptance of, and coping with, HIV positive status 2. Social support and disclosure 3. Experiences and beliefs about HIV medication and health care 4. Provider relationships and health system factors Qualitative analyses of interviews with clients indicated their experiences and concerns, and were summarized in these themes: 1. Life before and after knowing HIV status 2. Initiating and continuing ARV therapy 3. Adherence to, and side effects of, the ARV therapy treatment 4. Social support for people on ARV treatment vi 5. Positive outcomes of being on ARV treatment 6. Improving access to ARV treatment services Analyses of in-depth interviews with health care providers specified their experiences, and were categorized into three themes viz.: 1. Establishing and maintaining a good client-provider relationship 2. Facilitators of and adherence to ARV treatment 3. Barriers to access to treatmentItem The stress levels of parents whose children are on antiretroviral therapy(2010-06-25T11:51:24Z) Verster, Linley JoanHIV is having devastating effects on Africa as a whole and more specifically on Sub-Saharan Africa. Children are vulnerable to the disease and in most cases being hit the hardest. Parenting at the best of times involves some form of stress, and caring for a chronically ill child increases the parenting stress levels. Antiretroviral treatment has a positive effect on children with HIV, however it is not well understood what effect antiretroviral treatment has on the parenting stress levels of the caregivers of children with HIV. The aim of the study was to establish whether caregivers of children diagnosed with HIV show a change in stress levels after commencement of anti-retroviral treatment for their children. The objectives of the study were: to determine if any of the subsections of the PSI-SF were affected by the commencement of antiretroviral treatment in the children; to determine if a correlation existed between the CD4 count of the child and the parenting stress level of the caregiver and to determine whether the age of the child impacted on the scores of the PSI-SF. The demographic data of the participants were also analysed. This study involved secondary analysis of existing data for the study "A longitudinal study of neurodevelopmental delay in HIV positive children" conducted by Joanne Potterton utilising a longitudinal pre-post test study design where participants were compared to their own baseline scores. The Parenting Stress Index Short Form (PSI-SF) was used to establish the parenting stress levels within its three different subsections. The PSI-SF was completed by the caregivers at visit one, two and three. These visits were to the Harriet Shezi Clinic at Chris Hani Baragwanath Hospital, Soweto, Johannesburg. The children were antiretroviral naïve at visit one, and at visit two which was six months later, they commenced antiretroviral treatment with a six months follow-up which was visit three. iv Forty-five participants were included in the study. The paired ‘t’ test showed a significant change (‘p’ = 0.02) in the subsections Parent Child Dysfunctional Interaction and Difficult Child(change in mean -3.31 and -2.78 respectively), while the subsection of Parenting Distress had no significant change between visit one and visit two (change in mean -2.09). The change in mean between visit two and three was -1.84 for the Parental Distress subsection, 0.6 for the Parenting Child Dysfunctional Interaction subsection and 0.8 for the Difficult Child subsection. The paired ‘t’ test was applied to visit one and three and the subsection Parenting Distress showed the greatest positive change of 'p' = 0.00 with a change in mean of -3.93. There was no correlation between the CD4 count of the child and the PSI of the caregiver at any of the visits (r=-0.2, 0.11,0.3, p=0.15, 0.5, 0.06 respectively). There was no correlation between the age of the child and the parenting stress of the caregiver at any of the visits (r=0.13,0.08,0.5 p=0.39,0.6 and 0.1 respectively). The stress levels of the caregivers decreased over the study period however there was no significant decrease with the commencement of antiretroviral treatment.Item Self reported factors influencing adult patients' adherence to antiretroviral therapy at St Rita's Hospital(2009-11-12T13:00:21Z) Onwukkwe, Victor NnannaThe cornerstone in the fight against HIV/AIDS is prevention followed by the access to and use of highly active antiretroviral treatment (HAART). Adherence is the greatest patient- enabled predictor of treatment outcome for the patients on HAART, as good adherence leads to a decrease in disease progression and death. There is no ‘gold standard’ in the measurement of adherence. Also, factors that influence adherence and hence the prevalence of adherence differ across different settings making it necessary to determine local adherence prevalence as well as factors that might impact on it. This was a cross sectional study which assessed the prevalence of one- week adherence to antiretroviral therapy at St Rita’s hospital through an abridged version of the questionnaire developed by the Adult Aids Clinical Trials Group in the United States. Results from the questionnaires were compared to the results from a decrease in plasma viral load to undetectable limits within six months. The study found out that the prevalence of one- week adherence by self-report was 96.8% (95% CI: 93.2 – 98.9%). Using a decrease in viral load to undetectable limits within six months of initiating treatment as a tool to assess adherence, the prevalence in this study was 96%. A combined prevalence of 94% was found for this study. These results were identical to a few results locally but it was much higher than most local studies. The explanation for this apparent higher adherence rate might be that the study site has not reached its maximum capacity for the delivery of service as it is still operating at just below the staff/patient ratio recommended by the Department of health. The study also found out that being a member of an AIDS support group was a facilitator to adherence while lack of adherence counselling and monitoring is a barrier. Based on these findings it is therefore recommended that measures should be put in place to ensure improving existing adherence counselling and monitoring, encouraging patients to belong to at least one AIDS support group, more decentralization of antiretroviral therapy roll out to the districts that are yet to roll out and providing financial assistance through improved access to disability grants for those who qualify and income generating activities for the unemployed that do not qualify for disability grant.Item Organisational capacity of public sector ART provision in Gauteng Province and its impact on patient adherence : Case studies of two facilities(2008-10-23T09:41:52Z) Naidoo, Nicolette PreaIn November 2003, the Department of Health launched the Operational Plan for Comprehensive Care, Management and Treatment (CCMT) for South Africa. This policy has as its central goal universal access to antiretroviral therapy to 1 million people living with HIV by the end of 2007. National implementation of the operational plan began in April 2004 and as at the end of October 2006, South Africa had initiated 213 828 people onto ART through the Plan, making it the biggest programme in the world. Of these, 55 580 people had been placed on treatment in Gauteng Province. Despite these early achievements, there are concerns as to whether the South African public health sector can rise to the challenge of universal access while achieving good clinical outcomes and programme performance. As Venter (2006: 298) states, “the health sector is buckling under the current load, and currently does not have the capacity to do anymore than dent the numbers needed to treat, unless a radical restructuring of health services occurs.” A crucial factor in providing a comprehensive approach to HIV/AIDS is the reorientation of service delivery from acute to chronic disease care. In addition to the shift in focus to chronic disease management of HIV/AIDS, health system constraints need to be addressed. These include inadequate health system infrastructure and human resources. This study aimed to comprehensively assess organisational capacity to provide antiretroviral therapy (ART) in two public sector CCMT sites in Gauteng Province and the influence of these organisational factors on follow-up and adherence to ART, with the view to understanding whether public sector CCMT sites are able to deal with new challenges posed by the Plan. The objectives were to assess: (1) levels of follow-up and adherence in patients registered at the CCMT site, (2) dimensions of organisational capacity, drawing on internationally recognised chronic disease care frameworks, namely the Wagner Chronic Care Model (CCM) and Innovative Care for Chronic Conditions (ICCC). These dimensions were: presence of motivated and adequately staffed teams; delivery systems design; the quality of support systems; and facility information systems. 3) the similarities and differences between the two sites with respect to organisational capacity, follow-up and adherence. The two sites were selected through a stratified (CHC and hospital) random sample of CCMT sites in Region A of the province, excluding the long–standing and well-established academic hospital CCMT sites in the sampling frame. The two sites, located in a District Hospital in the West Rand and a Community Health Centre (CHC) in Central Witwatersrand, were visited between May and July 2006. They had initiated 540 and 1001 patients on ART respectively since October 2004. A multi-method health service evaluation of capacity in the HIV related services (ART/Wellness, VCT, PMTCT, and TB) was conducted. This consisted of 11 semi-structured interviews with facility and programme managers; review of registers and routine facility data; an observation checklist and mapping to assess the physical infrastructure of the facility, presence of management and health information systems; 35 self administered questionnaires to assess the levels of motivation of nursing staff at each site. Data on self-reported adherence and viral loads were obtained from a separate study involving exit interviews with 356 patients who had been attending the services for at least four months in the two sites.1 Of the 540 and 1001 patients enrolled in the two services, 69.8% and 69.3% were still in the service after 18 months at the hospital and CHC, respectively. The monthly drop-out rate at the hospital had risen fairly sharply towards the end of the 18 month period, attributed by the staff to growing difficulties in access to the site by new enrolments. Nevertheless, based on self-reports (3- day recall period), viral load measures, and loss to follow-up, adherence levels at both sites appeared to be in line with national and international best practice. The percentage of patients with undetectable virus was 76.2% and 74.4% at the hospital and CHC, respectively. Staffing of the CCMT sites matched the pre-requisites outlined by the National Department of Health for a ‘core’ health care team treating 500 patients. The CHC CCMT site, however, had more than 500 patients on ART and moreover was providing two services within one unit, i.e. ART/Wellness and VCT thus increasing the patient load. Sites were reaching saturation and this was due to the lack of sufficient space coupled with the high volumes of patients, shortage of certain scarce skills (in particular pharmacy staff), and the multiple responsibilities of nursing staff. In general, the staffing situation at the hospital appeared better. More staff had joined than left the hospital over the year prior to March 2006, and clinical workloads both in the ambulatory services and the CCMT site were less than at the CHC. Vacancy rates were low, at 13.8% and 4.8% for the hospital and CHC, respectively. Strong leadership of CCMT sites by motivated ART programme managers was displayed; site managers were highly respected and revered by staff. Based on ratings in a self-administered questionnaire, overall levels of motivation and organisational commitment at both sites appeared good, although, worryingly, a sizeable proportion of respondents in both sites agreed with statement “I intend to leave this hospital/clinic.” Lack of external support (from the HIV/AIDS, STI, TB Programme) and debriefing systems for programme managers and nursing staff was identified as weaknesses. With some exceptions, both sites showed evidence of strong ‘horizontal’ mechanisms of referral and coordination between HIV and AIDS related services within sites; however the PMTCT programme at the hospital was less co-ordinated and networked with other services. In addition, ART and PMTCT programme managers at the hospital indicated that the relationship between hospital services and surrounding clinics was poor. Apart from the lack of space at the CHC CCMT site, support systems were adequate. There were no reported drug stock outs and supply of drugs and general supplies was good at both sites. Both sites were able to offer a range of routine and HIV specific tests. A combination of paper and electronic based information systems were used at both sites, however, the hospital CCMT site used a mixture of standard and locally designed data collection forms compared to the CHC which mainly used standard Department of Health forms. The information systems were adequate in monitoring and evaluating patients and programme performance; however, the study highlighted the absence of a clear patient register for individual and programme monitoring and only cross sectional patient data was reported. There was also considerable duplication at the hospital in collecting and compiling patient information. The findings of the study suggest that the two sites, located in the ‘routine’ public sector environment of Gauteng Province have demonstrated ability to build organisational capacity for ART provision, through a degree of systems integration and design, decision support systems, generation and local use of information and motivated local champions. Through these elements of organisational capacity, both sites have achieved good adherence rates. The key factors to achieving this good programme performance were motivated local champions who drove programmes forward and good working relationships between the CCMT and other players. In light of the weaknesses identified, the following key recommendations are proposed: Review sites to identify the reasons for the high-drop out rate and address these issues Due to evidence of early saturation at the CHC, it is suggested that additional roll-out sites be established, or alternatively increase staffing and space at the CHC to meet the needs of the high patient load. In addition, well patients should be decanted to lower level services e.g. community based care organisations, thus reducing the burden on the site Pay attention to the physical infrastructure needs of clinic based sites, especially as they become saturated Foremost, the current Employee Assistance Programme (EAP) implemented in Gauteng Province should be strengthened and marketed so that staff members are more aware of the service and make use of it accordingly. Alternatively, a culture of “caring for the caregivers” should be cultivated, through for example, specialist assistance, debriefing sessions, and better external programme support from HIV/AIDS, STI, TB (HAST) managers Improve support and supervision of ART programmes by facilitating greater communication and feedback between sites and district, national and provincial levels of government. Adopt a strategy of “task shifting”, through better use of lay workers, counsellors, and mid level workers such as pharmacy assistants. Facilitate greater integration and coordination between the PMTCT programmes and other services, including the provision of VCT and training of staff. In addition, it is imperative that there is good integration between services provided by local and provincial Departments of Health Simplify and standardise information systems, particularly the development of clear patient registers to allow for cohort analysis.Item Client factors determining ARV adherence in Natalspruit hospital and Impilisweni CHC in Gauteng Province in 2006(2008-10-14T08:25:01Z) Kigozi, Lubwama JohnIntroduction: South Africa has embarked on a massive roll out of ARVs to more than 1.4 million people living with HIV/AIDS. Provision of ARVs to people living with HIV/AIDS encounters many challenges associated with adherence. Properly taken ARVs have been shown to reduce viral loads to undetectable levels and increase the CD4 count. This in turn leads to a drop in opportunistic infections and better health outcomes but the requirements for adherence are high. Several patient-related factors have been reported to affect adherence rates. Nonadherence on the other hand has been reported to lead to the development of drug resistant strains of HIV. It recognised that the resistance to ARVs can quickly lead to build up of highly resistant strains in the blood due to one week of missed medication. Aims and objectives: This study set out to identify factors which affect adherence to HAART among adults on HAART in two health facilities in Gauteng province in 2006.The main objectives were to assess the patient adherence using viral load response and self-report data. Secondly, the study was to determine factors that facilitate adherence and finally barriers to adherence at the two sites. Materials and methods: A cross sectional study was done at the two ARV facilities in Gauteng from July to November 2006. Two physiological methods -CD4 counts and plasma viral load, and one subjective-3 day recall self- report methods were used to asses adherence. Exit interviews and record reviews were done to collect data. Virologic outcome was the preferred surrogate marker for adherence. Univariate and bivariate analyses were done to determine measures of association. Measures of association (Chi square) at a 95% significance level for factors affecting adherence were then determined and results obtained. Results: The mean age was 36.9 years (range 18-70 years) and 73.5% were women. Self-report data (n=343) indicated 98.4% in the higher adherence category (taken 100% of their doses). Viral load data (n=343) showed that 88.8% were in the adherence lower category (<400 RNA copies). Viral load outcome (“adherence”) was significantly associated with the length on treatment (p<0.05) and patients who had been on treatment for 12-24 months had lower viral load than those who had been treatment for a shorter time (<12 months) or longer (>24months). However, gender (p=1.000), age (p=0.223), level of education (p=0.697) and access to social grants (p=0.057) were not associated with “adherence”. Socio-economic status was significantly associated with viral load outcome (p<0.01) as well as cost (n=185; p<0.05). Individuals who incurred the highest costs (>R25) were the least likely to adhere followed by those facing average costs (R15-25) compared to the reference group (< R15). Conclusion: Adherence rates of 88.8% suggest that respondents from both facilities can optimally adhere to their medication when they have been on ARVs for longer than a year. These are minimum adherence rates. There were factors that still hinder adherence at both the individual patient level. There is still a need for more targeted interventions especially towards men who were noted to have a relatively low uptake of HAART within the two sites.
