The study analysed and compared data from patients' medical and pharmacy refill records to identify correlations between CD4 cell counts and adherence to antiretroviral drugs at Katutura Intermediate Hospital (KIH) in Windhoek, Namibia. The study investigated whether the pharmacy refill adherence measurement methodology could predict immunological recovery through increased CD4 cell counts. There was a positive but weak relationship between adherence and CD4 cell counts. Although the pharmacy refill records could predict immunological response it was not sensitive enough and should be used in combination with other adherence measurement tools. / Public Health / M.A. (Public Health)

This study attempted to identify personal (patient-related) factors influencing anti-retroviral therapy (ART) adherence in Addis Ababa, Ethiopia. A quantitative, descriptive, cross-sectional and analytical design was used. Structured interviews were conducted with 355 ART patients. The findings revealed that stigma, discrimination, depression and alcohol use negatively affected patients’ ART adherence levels. However, patients’ knowledge levels had no influence on their ART adherence levels, contrary to other researchers’ reports. Addressing stigma and discrimination at community levels might enhance patients’ abilities to take their medications in the presence of others. Healthcare professionals should be enabled to diagnose and treat depression among ART patients during the early stages. Non-adherent ART patients should be counseled about possible alcohol abuse. / Health Studies / M.A. (Public Health with specialisation in Medical Informatics)

The objectives of the study were (1) to quantify adherence rate among the study participants in the ART unit and (2) to identify factors that contribute to non-adherence. This cross sectional study was carried out at Nekemete referral clinic. Data was collected using a self-developed structured questionnaire where a total of 338 participants grouped into adherent and non-adherent based on a score derived from an adherence assessment were interviewed. Data was analysed using the Statistical Package for Social Sciences (SPSS) version 17.0. By using multivariate analysis of variables identified as correlates of adherence, non-adherence was common among those; with age between 18-30 yrs, with no education, who were not married, who had no pipe water supply, those with no electricity in the house, who perceived had no access to assistance from providers, who perceived the health care providers (HCPs) did not keep information confidentially, who had a language barrier with providers, and who were treated with a psychiatric illness. The study concludes that adherence is multi-factorial and varies significantly by individual and care setting. Psychosocial factors were found to impact adherence and should be analysed in more detail by further studies. Three psychosocial factors were independently associated with poor adherence: the study found that patients perceiving poor access; those perceiving problems in information confidentiality (and possibly experiencing stigmatisation); and having psychiatric morbidity (and possibly with less social support) are more likely to be non-adherent. Furthermore, individuals without electricity and those without piped water supply, implying low income, are at risk for non-adherence / Health Studies / M.A. (Public Health)

The earlier optimism generated by the efficacy of antiretroviral drugs in human immuno-deficiency virus (HIV) patients has been dissipated in the face of the enormous chal-lenge of maintaining a nearly perfect adherence indefinitely. This study set to determine the influence of HIV adherence self-efficacy and beliefs about medicines on antiretrovi-ral therapy adherence, with the aim of developing a framework for enhancing antiretrovi-ral therapy (ART) adherence through focused intervention on modifiable factors from study variables that are strongly associated with ART adherence. A descriptive correlational design was used to assess the predictive relationships of HIV adherence Self-Efficacy, Beliefs about Medicines and ART adherence among 232 HIV-infected patients in a large public health facility in Pretoria. Participants' medication be-liefs were assessed using the Beliefs about Medicines Questionnaire, HIV adherence self-efficacy was assessed with HIV adherence self-efficacy scale (HIV-ASES) and ART adherence was assessed using the AIDS Clinical Trial Group questionnaire. Pearson correlation analysis was used to assess bivariate associations among the variables, and multiple regression analysis was used to examine the relationships among the inde-pendent variables and ART adherence. Mean adherence for the 232 participants was 95% (SD=13.2). Correlation analysis re-vealed positive bivariate associations between perceived general harm and overuse of medications, and ART adherence (p<0.05); between specific necessity and concerns about ARVs, and perceived general harm and overuse of medications (p<0.05); be-tween HIV adherence self efficacy and ART non-adherence (p<0.05). Multiple regres-sion analysis showed significance for perceived general harm and overuse of medica-tions on ART adherence (F(1;231)=11,583;p<0,001) with perceived general harmful ef-fects and overuse of medications explaining 4.8% of the variance. There was signifi-cance for HIV adherence self-efficacy on ART non-adherence (F(1;41)=4.440; p<0.041), with HIV-ASES explaining 9,8% of the variance. Based on the results, a framework for enhancing ART adherence was developed. Activities in the framework consist of baseline screening for adherence facilitators and barriers using the beliefs about medicine questionnaire and HIV ASES, this is followed by focused interventions on identified barriers of ART adherence / Health Studies / D.Litt. et Phil.

The purpose of the study was to describe factors contributing to mortality among HIVinfected people on Isoniazid Preventive Therapy (IPT) in Botswana. A quantitative, explorative, descriptive study was used and 80 records of deceased IPT respondents were reviewed through the use of a checklist. The demographic factors, baseline physical examination, hospitalisation and drug history were taken into consideration. Out of the deceased patients, 75% were female. The major findings showed that 100% (N=80), the most highly indicated causes of death were gastroenteritis (18.75%), cryptococcal meningitis (17.5%) andpneumonia (16.25%). Of the patients (28.75%) who died before completing the six months of IPT. The causes of death were gastroenteritis (21.7%), symptoms and signs of bacterial pneumonia (17.4%), cryptococcal meningitis (13%), Pulmonary Tuberculosis (PTB) (13%), septicaemia (13%), and murder (13%). It has been recommended that there should be reorganisation of services of care for HIV-infected persons, such as provision of Cotrimoxazole Prophylaxis Therapy (CPT) and Antiretroviral Therapy (ART) to ensure holistic approach care. The future study should include HIV-infected children on IPT using the same or modified objectives. The conclusion drawn was that disintegrated interventions of IPT, CPT and ART and lack of holistic care for PLHIV lead to opportunistic infections that caused mortality on patients on IPT. / Department of Health Studies / M.A. (Public Health)

Adherence to long-term medications has remained a problem among adolescents worldwide. Antiretroviral therapy adherence is a wide-reaching challenge among HIV positive adolescents. The aim of this study is to explore and describe poor ART adherence among HIV positive adolescents in Maseru: influential factors and the need of social work support. Qualitative approach was used, following an explorative, descriptive and contextual research design. The research was conducted at BCMCOE Lesotho. Data was collected by using semi-structured in-depth interviews and purposive sampling was applied to select a sample of adolescents who are HIV positive and who have poor adherence to ART. Data was analysed according to the framework provided by Tesch (in Creswell 2003). Guba’s model (in Krefting 1991) was employed for data verification. Conclusions were drawn and recommendations were made about factors influencing adherence of adolescents to ART and support needed from social workers. / Social Work / M.A.(S.S.)

The purpose of this study was to determine factors affecting non-adherence to Anti-retroviral therapy among AIDS patients. A cross sectional quantitative survey, was used. Structured interviews were conducted with 300 ART patients. Data were analysed using SPSS version 13 and presented in charts, graphs and frequency tables. Motivators of good adherence were identified as disclosure of HIV positive status to more than one person, frequent adherence counselling, self-efficacy to adhere to ART, positive interactions between patients and healthcare providers; and using an adherence partner. Barriers to adherence were forgetfulness, transportation costs to and from the clinic, time away from work and side effects. There was a strong positive correlation between adherence, CD4 counts and viral load. Adherence was closely tied to immunologic and virologic improvements. Respondents with poor adherence were likely to have unsuppressed viral loads (OR 12.98, 95%, CI 4.9-34). / Health Studies / Masters of Public Health

This study assessed healthcare providers’ knowledge, attitudes and practices towards IPT provision for people living with HIV (PLHIV) in Addis Ababa, the capital city of Ethiopia. A quantitative, descriptive, cross-sectional study design was used for the study and data was collected using a self-administered questionnaire from 104 clinicians working in ART clinics. The findings show that healthcare providers who participated in this study had a mean value of high knowledge, positive attitude and good practice towards IPT provision for PLHIV. Significant association was found between knowledge and attitude (P=0.000) but no significant associations were found between knowledge and practice, attitude and practice as well as between the type of facility (public/private) and level of practice. This implied that, the low level of IPT implementation in Addis Ababa doesn’t seem due to health care providers’ lack of knowledge and resistance to provide IPT for people living with HIV. As a result, the researcher recommends for further researches of other possible factors like; the reliability of IPT information/data management, drug supply and the leadership and governance of the health system that IPT program is a direct concern. / Health Studies / M.A. (Public Health (with specialisation in Medical Informatics))

The effects of HIV/AIDS and subsequent opportunistic infections and/or associated conditions on the development of infected children are substantial. Considerable delays and/or disorders in communication development have been noted in the HIV/AIDS infected child, as well as the need for Early Communication Intervention (ECI) services for this population. A dearth of locally relevant data regarding the speech, language and hearing development of HIV/AIDS infected children within the South African context currently exists. The objective of this study was to describe the characteristics of a group of HIV/AIDS infected children being managed at an outreach clinic of regional hospital in Gauteng. A cross-sectional, retrospective, non-experimental, descriptive, quantitative research design was used in this study. The main objective was achieved by analysing the clinic records of 203 children infected with HIV/AIDS between the ages of 0 – 5 years 11months through the use of a pre-designed checklist. A questionnaire completed by four medical doctors practicing at the HIV/AIDS clinic within the hospital was also used. This allowed for the perceptions and practices of the medical doctors to be described. Results revealed that the majority HIV/AIDS infected children being managed at the outreach clinic were significantly immunocompromised and diagnosed with Stage III or Stage IV HIV/AIDS infection. Furthermore, results indicated the presence of several opportunistic infections and HIV/AIDS associated conditions (such as Tuberculosis, Candidiasis and Encephalopathy). A positive finding was that 76% of the HIV/AIDS infected children (n=153) were receiving Highly Active Antiretroviral Therapy (HAART) at the time of data collection. The most outstanding finding was that very few of the children with HIV/AIDS being managed at the outreach clinic were recorded as having speech, language and/or hearing delays and/or disorders. Similarly, referrals to other professionals as recorded in the children’s hospital records seemed to be limited to Social Workers and Dietitians, with only one child recorded as being referred to a Speech-Language Therapist and Audiologist for further management. It was unclear whether more children were in fact referred for additional intervention by other professionals and this was simply not recorded in the children’s records, or whether these referrals were in fact not made. Results from the questionnaires completed by the medical doctors working with the pediatric HIV/AIDS population within the outreach clinic were significant. Findings indicated that the majority of the respondents believed that HIV/AIDS infected infants were more at risk for developmental and communicative delays and/or disorders than the general population, and that this population would likely benefit from Speech-Language Therapy and/or Audiology intervention services. Respondents indicated that medical doctors working with the pediatric HIV/AIDS population were often not adequately informed regarding the effects of HIV/AIDS on communication development and that they would benefit from further training in this regard. The need for further research regarding the characteristics of the pediatric HIV/AIDS population, particularly on a larger sample, was described. This would assist in the development of a guideline for ECI service delivery for children infected with HIV/AIDS. The need for further training of other professionals regarding the effects that HIV/AIDS has on the communication development of the infected child, to assist with necessary referrals and teamwork, was also highlighted. AFRIKAANS : Suid-Afrika is een van die lande ter wêreld, wat die hoogste voorkoms van Menslike Immuniteitsgebrekvirus/ Verworwe Immuniteitsgebreksindroom (MIV/VIGS), toon - met die pediatriese populasie op die voorfront van hierdie epidemie. Die effek wat MIV/VIGS en opeenvolgende opportunistiese infeksies en/of ander geassosieerde toestande op die ontwikkeling van kinders het, is verreikend. Internasionale literatuur beskryf agterstande en/of akwykings in die kommunikasie ontwikkeling van kinders wat met MIV/VIGS geinfekteer is. Die behoefte vir Vroeë Kommunikasie Intervensie (VKI) vir hierdie populasie word ook gemeld. Daar bestaan egter slegs ‘n beperkte hoeveelheid relevante, plaaslike literatuur met betrekking tot die spraak-, taal- en gehoorontwikkeling van kinders met MIV/VIGS binne die Suid-Afrikaanse konteks. Die doelwit van hierdie studie was om die kenmerke van ‘n groep kinders, wat met MIV/VIGS besmet is en by ‘n streekshospitaal in Gauteng behandel word, te beskryf. ‘n Kwantitatiewe, nie-eksperimentele, terugwerkende, dwarsdeurige, beskrywende navorsingsontwerp is gebruik. Die hoofdoelwit was bereik deur die kliniekrekords van kinders wat met MIV/VIGS besmet is, te analiseer deur van ‘n vooraf-ontwerpte merklys gebruik te maak. Data is ook ingesamel deur middel van vraelyste wat deur mediese dokters, wat by MIV/VIGS klinieke binne die hospitale werk, voltooi is. Dit het toegelaat dat die persepsies en praktyke van die mediese dokters ook beskryf kon word. Resultate het getoon dat die meerderheid kinders met MIV/VIGS, wat by klinieke behandel word, se immuunsisteme ernstig onderdruk was en dat hulle met stadium III of stadium IV van MIV/VIGS gediagnoseer was. Die resultate het verder ook die voorkoms van verskeie opportunistiese infeksies en MIV/VIGS geassosieerde toestande aangedui. ‘n Positiewe bevinding was dat 76% van die kinders (n=153), wat met MIV/VIGS geinfekteer was, tydens die proses van data-insameling reeds Hoogsaktiewe Antiretrovirale Terapie (HAART) ontvang het. Die mees uitstaande bevinding was dat slegs ‘n geringe hoeveelheid kinders met MIV/VIGS by die kliniek, as met ‘n agterstand en/of afwyking in spraak, taal en/of gehoor, aangeteken is. Beperkte verwysings na ander professionele persone is ook in die kliniekrekords opgemerk. Verwysings was beperk tot Maatskaplike Werkers en Dieëtkundiges. Daar was slegs een aantekening van ‘n kind wat vir behandeling na ‘n Spraak- en Taalterapeut en Oudioloog verwys is. Dit is egter onduidelik of daar werklik meer verwysings na ander professionele persone gemaak is, maar net nie in die kinders se kliniekrekords aangedui is nie, of dat daar werklik min verwysings na ander professionele dissiplines gemaak is. Bykomend, was die resultate van voltooide vraelyste deur mediese dokters, wat met die pediatriese MIV/VIGS populasie in die kliniek werk, insiggewend. Bevindings dui aan dat die meerderheid proefpersone, wat aan die studie deelgeneem het, van mening is dat kinders wat met MIV/VIGS besmet is wel ‘n hoër risiko toon vir ontwikkelings- en kommunikasie agterstande en/of afwykings in vergeleke met die algemene populasie. Die proefpersone is verder ook van mening dat hierdie populasie wel van spraak- en taalterapie en/of oudiologiese intervensie sal baatvind. Proefpersone het verder aangedui dat mediese dokters, wat met die pediatriese MIV/VIGS populasie werk, nie ten volle ingelig is omtrent die effek van MIV/VIGS op kommunikasie ontwikkeling en dat hulle van verdere opleiding sal baatvind. Die behoefte vir verdere navorsing in die veld van pediatriese MIV/VIGS en kommunikasie ontwikkeling, binne die Suid-Afrikaanse konteks, word in hierdie studie beskryf. Dit sal as riglyn vir VKI dienslewering aan hierdie populasie dien. Daar is ook ‘n groot behoefte vir verdere opleiding van ander mediese professionele persone met betrekking tot pediatriese MIV/VIGS en die effek wat die op die kind se kommunikasie ontwikkeling het. / Dissertation (MCommunication Pathology)--University of Pretoria, 2010. / Speech-Language Pathology and Audiology / unrestricted
