An investigation into the knowledge levels of clients on long term tuberculosis treatment at Kwekwe general hospitalSamkange, Porai Mary 30 November 2005 (has links)
The study investigated the knowledge levels of clients on long-term tuberculosis (TB) treatment at Kwekwe General Hospital, Zimbabwe. A quantitative, descriptive research design was chosen and data was collected using a structured questionnaire with a convenience sample of 60 clients on TB treatment and 10 professional nurses.
The major findings of the study were that although clients had some knowledge about their condition, there was a lack of knowledge regarding critical aspects such as information on drug-resistant TB and the Directly Observed Therapy Short Course. The professional nurses experienced constraints such as insufficient time for appropriate health education and home visits.
Based on the study findings and conclusions, several recommendations were made. / Health Studies / Thesis(M.A(Health Studies))

Adherence by health care providers' National Tuberculosis guidelinesAragaw, Getahun Sisay 11 1900 (has links)
This study examined healthcare providers’ adherence to the national Tuberculosis
guidelines (NTG) during the diagnosis and treatment of TB in Addis Ababa, Ethiopia
using a descriptive, cross-sectional study design. Data were collected from 233
medical records using checklists.
Adherence of healthcare providers to the NTG during the diagnosis of TB was 60.9%
(n=67) for female and 56.1% (n=69) for male TB patients. However, 91.8% (n=101)
female and 90.2% (n=111) male TB patients had been prescribed the correct
numbers of anti-TB pills, complying with the NTG recommendations. There was an
over-diagnosis of smear negative pulmonary Tuberculosis (PTB) as only 2.6% (n=2)
of the 76 smear negative PTB patients were diagnosed correctly.
Healthcare providers’ compliance with the NTG could be enhanced by providing
appropriate in-service education, maintaining accurate records of all TB patients and
providing supportive supervision to identify and address shortcomings.

Treatment interruption in tuberculosis patients in a district of NamibiaZaranyika, Trust 02 1900 (has links)
The purpose of the study was to investigate the factors associated with the interruption of tuberculosis treatment in the Swakopmund district of Namibia. A descriptive cross-sectional survey was conducted. Data was collected using a structured questionnaire administered by interviewers. The population consisted of both treatment interrupters and non-interrupters. The total sample was 143 respondents. The findings revealed that three factors were significantly associated with TB treatment interruption, namely a lack of formal education (p = 0.032), lack of access to media (p = 0.017), and clinic opening times (p = 0.000). Recommendations made include improving the support given to TB patients, increasing their understanding of TB and adopting new research and technology. / Health Studies / M.A. (Public Health)

An investigation into the lung function, health-related quality-of-life and functional capacity of a cured pulmonary tuberculosis population in the Breede Valley, South Africa : a pilot studyDaniels, Kurt John 04 1900 (has links)
Thesis (MScPhysio)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Background: Pulmonary tuberculosis (PTB) remains a major concern worldwide. Although PTB is curable, both the disease and its treatment may have considerable medical, social and psychological consequences which may result in a decreased quality of life and functioning. Characterization of the functional capabilities of PTB patients post-treatment and the impact of PTB on their quality of life may identify a need for more holistic management of PTB treatment that extends beyond microbiological cure.
Methods:
Firstly, an in-depth scoping review was conducted using the following key words: Pulmonary tuberculosis (MESH term) and Health related quality of life (HRQoL), Pulmonary tuberculosis (MESH term) and Spirometry and Pulmonary tuberculosis (MESH term) and Six minute walk test or 6MWT to review the current literature reporting on the HRQoL, lung function measurements and exercise capacity of a PTB population (Chapter 2).
Secondly, a cross-sectional, quantitative, descriptive study was conducted. The study setting included five primary health care facilities (PHCF) in the Breede Valley sub-district of the Cape Winelands East District, Western Cape, South Africa. Adult patients diagnosed with PTB, 18 years and older and who were successfully managed through the Cape Winelands District Health Care system were considered for the study if they had least two negative sputum sample results and had completed at least five months of anti-tuberculosis treatment. Post treatment bronchodilator lung function tests, health related quality of life using the BOLD core questionnaire and six minute walk test distance (6MWD) was measured.
Findings:
The comprehensive broad search of the literature yielded a total of 2446 articles. A total of 2422 articles were excluded since the title; abstract or full text article did not conform to the review question or were eliminated as duplicates across databases. Twenty-seven articles divided amongst the three subsections i.e. PTB and HRQoL (n=13), PTB and Spirometry (n=9) and PTB and exercise capacity (n=6), were included in the review.
In the cross-sectional study, 328 names were obtained from the TB registers of the five included PHCF of which 45 patients were included in the study (56% male; mean age, 39.88±10.20 years). The majority of patients (n= 206; 63%) were not contactable, and could not be recruited. Approximately half the total sample, (n=23; 52%) presented with normal lung function while n=11 (25%) presented with a restrictive pattern, n=9 (21%) presented with an obstructive pattern and only n=1 (2%) presented with a mixed pattern (defined as FEV1<80% predicted, FVC<80% predicted and FEV1/FVC<0.7). The mean six minute walk distance (6MWD) was 294.5m±122.7m. Respondents scored poorly on all sub-domains of the SF-12v2 except vitality. Role emotional and role physical scored lowest with mean scores of 28.1 and 35.27 respectively, while vitality scored the highest with 52.78. Stellenbosch University https://scholar.sun.ac.za

Conclusion
The findings of this thesis suggest that even after microbiological cure, PTB patients may suffer from a decreased quality of life, impaired lung function and a decreased exercise capacity. Specific challenges to data collection in a rural region were identified; which included patient recruitment, field testing of exercise capacity (6MWD), and the generalizabilty of standardized questionnaires in rural regions. The findings of this pilot study serves to inform the planning of a larger observational study, in the rural Cape Winelands of the Western Cape, South Africa. / AFRIKAANSE OPSOMMING: Agtergrond
Pulmonêre tuberkulose (PTB) wek wêreldwyd steeds groot kommer. Hoewel dit geneeslik is, kan die siekte sowel as die behandeling daarvan beduidende mediese, maatskaplike en sielkundige gevolge hê, wat lewensgehalte en funksionering kan knou. Die tipering van PTB-pasiënte se funksionele vermoëns ná behandeling sowel as die impak van PTB op hul lewensgehalte kan dalk dui op ’n behoefte aan die meer holistiese bestuur van PTB-behandeling, wat méér as blote mikrobiologiese genesing insluit.
Metodes
Eerstens is ’n diepgaande bestekstudie aan die hand van die volgende trefwoorde onderneem: pulmonêre tuberkulose (MeSH-term) en gesondheidsverwante lewensgehalte (HRQoL), pulmonêre tuberkulose (MeSH-term) en spirometrie, en pulmonêre tuberkulose (MeSH-term) en die ses minute lange stapafstandtoets (6MWT). Na aanleiding daarvan is die huidige literatuur oor die HRQoL, longfunksiemetings en oefenvermoë van ’n PTB-populasie bestudeer (hoofstuk 2).
Tweedens is ’n kwantitatiewe, beskrywende deursneestudie onderneem. Die studie-omgewing het bestaan uit vyf fasiliteite vir primêre gesondheidsorg in die Breedevallei-subdistrik van die streek Kaapse Wynland-Oos, Wes-Kaap, Suid-Afrika. Volwasse pasiënte van 18 jaar en ouer wat met PTB gediagnoseer is en suksesvol deur die distriksgesondheidsorgstelsel van die Kaapse Wynland-streek bestuur word, is vir die studie oorweeg indien minstens twee van die pasiënt se sputummonsters TB-negatiewe resultate opgelewer het en die persoon reeds minstens vyf maande vir tuberkulose behandel is. Studiemetings het ingesluit brongodilator-longfunksietoetse ná behandeling, gesondheidsverwante beoordelings van lewensgehalte met behulp van die BOLD-vraelys, en die aflegging van ’n ses minute lange stapafstandtoets (6MWT).
Bevindinge
Die omvattende breë soektog van die literatuur het 'n totaal van 2446 artikels opgelewer. 'n Totaal van 2422 artikels is uitgesluit, aangesien die titel; abstrakte of volledige teks artikel het nie voldoen aan die navorsings vraag, of is uitgeskakel as duplikate oor databasisse. Sewe en twintig artikels verdeel tussen die drie onderafdelings, naamlik PTB en HRQoL (n = 13), PTB en Spirometrie (n = 9) en PTB en oefening kapasiteit (n = 6), is ingesluit in die oorsig.
In die deursneestudie is 328 name uit die TB-registers van die vyf ondersoekpersele bekom. Altesaam 45 pasiënte (56% mans; gemiddelde ouderdom 39.88±10.20 jaar) is by die studie ingesluit. Die oorgrote meerderheid pasiënte (n = 206; 63%) kon nie bereik word nie, en dus ook nie gewerf word nie. Ongeveer die helfte van die algehele steekproef (n = 23; 52%) se longfunksie was normaal; n = 11 (25%) het ’n restriktiewe patroon getoon; n = 9 (21%) ’n obstruktiewe patroon, en slegs n = 1 (2%) ’n gemengde patroon (wat omskryf word as ’n FEV1-voorspellingswaarde van <80%, ’n FVC-voorspellingswaarde van <80%, en FEV1/FVC van <0.7). Die gemiddelde afstand wat in die ses minute lange staptoets afgelê is (6MWD), was 294,5 m±122,7 m. Respondente behaal swak Stellenbosch University https://scholar.sun.ac.za

op al die sub-domein van die SF-12v2 behalwe vitaliteit. Rol emosionele en rol fisiese behaal laagste met die gemiddelde tellings van 28.1 en 35,27 onderskeidelik, terwyl vitaliteit behaal die hoogste met 52,78.
Gevolgtrekking
Die bevindinge van hierdie tesis gee te kenne dat PTB-pasiënte selfs ná mikrobiologiese genesing dalk swakker lewensgehalte, verswakte longfunksie en ’n afname in oefenvermoë ondervind. Bepaalde uitdagings vir data-insameling in ’n landelike omgewing is uitgewys, onder meer pasiëntewerwing, veldtoetsing van oefenvermoë (6MWD) en die veralgemeenbaarheid van gestandaardiseerde vraelyste in landelike gebiede. Die bevindinge van hierdie proefstudie kan gebruik word om die beplanning van ’n groter waarnemingstudie in die landelike Kaapse Wynland-streek in die Wes-Kaap, Suid-Afrika, te rig.

Economic support to improve TB treatment outcomes in South Africa : a pragmatic cluster randomized controlled trialLutge, Elizabeth Eleanor 12 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: This thesis focused on the provision of economic support to improve the outcomes of patients on TB treatment. Although the association between poverty and tuberculosis is generally acknowledged, there is little evidence to guide the use of economic interventions to improve tuberculosis control. In South Africa, a high burden country with extensive poverty, such evidence is particularly important.
The first part of this thesis is a Cochrane systematic review of evidence from randomized controlled trials regarding the effectiveness of economic support among patients with tuberculosis. Eleven trials were included: ten conducted among marginalised groups in the United States on economic support for people on prophylactic treatment for latent TB; and one from Timor-Leste on economic support for patients with active TB. The review found that the use of economic interventions in patients with latent TB may increase the return rate for reading tuberculin skin test results, probably improves clinic re-attendance for initiation or continuation of prophylaxis and may improve completion of prophylaxis, compared to normal care. However, it is uncertain if economic support improves treatment completion in patients with active TB (low quality evidence).
The second part of the thesis reports the findings of a pragmatic, cluster randomized controlled trial to evaluate the feasibility and effectiveness of delivering economic support to patients on treatment for active TB in South Africa. Patients with drug sensitive pulmonary TB were offered a monthly voucher valued at ZAR120 until completion of treatment or a maximum of eight months. Patients in control clinics received usual TB care. A parallel process evaluation provided contextual information to explain the trial findings. The qualitative component of this evaluation consisted of in-depth interviews with a sample of trial participants, including patients, nurses and health managers, to assess responses to the voucher and its administration. The quantitative component included a survey of patients’ household expenditure to assess patients’ levels of poverty and the effects of the voucher on these, and an analysis of the goods on which patients spent their vouchers.
4091 patients were included in the trial: 1984 in the control arm (10 clinics) and 2107 in the intervention arm (10 clinics). Intention to treat analysis showed a small but non-significant improvement in treatment success rates in intervention clinics (intervention 76.2%; control 70.7%; risk difference 5.6% (-1.2; 12.3%), p = 0.107). Fidelity to the intervention was low, partly because nurses preferred to issue vouchers based on perceived financial need, rather than on eligibility. Logistical difficulties in delivering vouchers to clinics also undermined fidelity. The vouchers did not significantly increase patients’ household expenditure, but were experienced by patients as helpful, especially in providing more food with which to take their tablets.
Factors related to the administration of economic support may undermine its effectiveness in improving TB treatment outcomes. Further research is needed to explore how best to deliver such economic support to those eligible to receive it, particularly in low and middle income countries where the burden of tuberculosis is highest. / AFRIKAANSE OPSOMMING: Hierdie tesis was toegespits op die verlening van ekonomiese steun om die uitkomste van pasiënte op tuberkulose- (TB-) behandeling te verbeter. Hoewel die verband tussen armoede en TB in die algemeen erken word, is daar nie veel bewyse om die gebruik van ekonomiese intervensies ter verbetering van TB-beheer te staaf nie. In Suid-Afrika – ’n land met ’n hoë TB-las en wydverspreide armoede – is sulke bewyse veral belangrik.
Die eerste deel van hierdie tesis behels ’n sistematiese Cochrane-oorweging van bewysmateriaal afkomstig van verewekansigde, gekontroleerde proewe oor die doeltreffendheid van ekonomiese steun aan pasiënte met tuberkulose.
Altesame 11 proewe is ingesluit: Tien is gedoen onder gemarginaliseerde groepe in die Verenigde State met die fokus op ekonomiese ondersteuning aan mense wat profilaktiese behandeling vir latente TB ontvang het. Een, van Timor-Leste, was gefokus op ekonomiese ondersteuning aan pasiënte met aktiewe tuberkulose. Die ondersoek het aan die lig gebring dat, vergeleke met normale sorg, die gebruik van ekonomiese intervensies by pasiënte met latente tuberkulose tog die omdraaikoers vir die lees van tuberkulien-veltoetsresultate kan verhoog, waarskynlik hertoelating tot klinieke vir die inisiëring of voortsetting van profilakse verbeter, en die voltooiing van profilakse kan verbeter.
Die tweede gedeelte van die tesis behels ’n verslag oor die bevindings van ’n pragmatiese, trosverewekansigde gekontroleerde proef, om te bepaal hoe doenlik en doeltreffend dit sou wees om ekonomiese steun te verleen aan pasiënte wat in Suid-Afrika vir aktiewe tuberkulose behandel word. Pasiënte met middelsensitiewe pulmonêre tuberkulose het tot en met die voltooiing van hul behandeling, of tot ’n maksimum van agt maande, ’n maandelikse koopbewys ter waarde van ZAR120 ontvang. Pasiënte in kontroleklinieke het die gewone TB-sorg ontvang. ’n Parallelle prosesevaluering het kontekstuele inligting voorsien ter verklaring van die bevindinge van die proef. Die kwalitatiewe komponent van hierdie evaluering het bestaan uit diepte-onderhoude met ’n steekproef van alle deelnemers aan die proefneming, insluitend pasiënte, verpleegpersoneel en gesondheidsbestuurders, om hul reaksies te bepaal op die koopbewys self sowel as op die administrasie daarvan. Die kwantitatiewe komponent het ’n opname oor pasiënte se huishoudelike besteding ingesluit, ter vasstelling van hul armoedevlak en die moontlike uitwerking van die koopbewys daarop, asook ’n ontleding van die goedere waarop pasiënte hul koopbewyse bestee het.
Altesame 4 091 pasiënte is by die proef ingesluit – 1 984 in die kontrole-afdeling (10 klinieke) en 2 107 in die intervensie-afdeling (10 klinieke). ’n Voorneme-om-te-behandel- (ITT-) ontleding toon ’n klein dog nie-betekenisvolle verbetering in behandelingsuksessyfers in intervensieklinieke (intervensie 76,2%; kontrole 70,7%; risikoverskil 5,6% (-1,2; 12,3%), p = 0.107). Getrouheid aan die intervensie was laag – deels omdat verpleegkundiges verkies het om die koopbewyse op grond van veronderstelde finansiële behoeftigheid eerder as volgens die studiekriteria uit te deel. Die koopbewyse het nie pasiënte se huishoudelike besteding beduidend verhoog nie, maar pasiënte het dit wél as nuttig ervaar, veral omdat hulle daarmee meer kos kon koop om saam met hul pille in te neem.
Faktore wat verband hou met die administrasie van ekonomiese ondersteuning kan die doeltreffendheid van sodanige steun in die verbetering van TB-behandelingsuitkomste ondermyn. Verdere navorsing word vereis om te verken wat die beste manier sou wees om sodanige ekonomiese steun te bied aan diegene wat daarvoor in aanmerking kom, veral in lae- en middel-inkomstelande, waar die TB-las die hoogste is.

Treatment outcomes of patients with MDR-TB and its determinants at referral hospitals in EthiopiaMengistu, Kenea Wakjira 01 1900 (has links)
Text in English / Aim: The aims of this study were to investigate the treatment outcomes of patients with MDRTB
and its determinants at referral hospitals in Ethiopia. The study also aims to develop a
conceptual model for enhancing treatment of patients with MDR-TB in Ethiopia.
Design and methods: A concurrent mixed methods design with quantitative dominance was
used to investigate treatment outcomes of patients with MDR-TB and its determinants.
Results: A total of 136 (n=136) patients with MDR-TB participated in the study, 74 (54%)
were male and 62 (46%) were female. Forty-one (31%) of the patients had some co-morbidity
with MDR-TB at baseline, and 64% had body mass index less than 18.5kg/m2. Eight (6%) of
the patients were diagnosed among household contacts. At 24 months, 76/110 (69%) of the
patients had successfully completed treatment, but 30/110 (27%) were died of MDR-TB. Multivariable
logistic regression revealed that the odds of unfavourable treatment outcomes were
significantly higher among patients with low body mass index (BMI <18.5kg/m2) (AOR=2.734,
95% CI: 1.01-7.395; P<0.048); and those with some co-morbidity with MDR-TB at the
baseline (AOR=4.260, 95%CI: 1.607-11.29; p<0.004).
The majority of the patients were satisfied with the clinical care they received at hospitals.
But as no doctor was exclusively dedicated for the MDR-TB centre, patients could not receive
timely medical attention and this was especially the case with those with emergency medical
conditions. The caring practice of caregivers at the hospitals was supportive and empathic
but it was desperate and alienating at treatment follow up centres. Patients were dissatisfied
with the quality and adequacy of the socio-economic support they got from the programme.
Despite the high MDR-TB and HIV/AIDS co-infection rate, services for both diseases was not
available under one roof.
Conclusions: Low body mass index and the presence of any co-morbidity with MDR-TB at
the baseline are independent predictors of death among patients with MDR-TB. Poor
communication between patients and their caregivers and inadequate socio-economic
support were found to determine patients’ perceived quality of care and patients’ satisfaction
with care given for MDR-TB. / Health Studies / D. Litt et Phil. (Health Studies)

Determinants of adherence to tuberculosis therapy among patients receiving Directly Observed Treatment from a district hospital in Pretoria, South AfricaAiyegoro, Olayinka Ayobami January 2016 (has links)
Magister Public Health - MPH / Background: The incidence of tuberculosis in South Africa last measured at 834 in 2015 as reported by the World Bank. Out of these cases, only 54% cured and 13% of patients stop taking treatment. In Pretoria, Gauteng, comprehensive TB services are available in 87% of clinics and all these clinics offer the Directly Observed Treatment Short-course (DOTS) programme and help to diagnose TB and trace contacts. However, the average Pretoria district DOTS coverage has decreased from 88.8% to 84.7% in the last few years. The health district's cure rate as at 2012 is 61%, and its average rate of successful treatment of all new smear positive cases is 66% since 2005. Certain factors that determine patients' adherence towards TB treatment have been identified to include demographic, psychosocial and health system related factors. However, the WHO identified factors responsible for or predisposing patients to discontinue the DOTS programme have not been investigated in the study setting. Aim: The aim of this study was to assess the determinants of adherence to DOTS therapy amongst TB patients who commenced TB treatment at the TB clinic of a district hospital during April – June 2014. Methodology: A quantitative study was conducted using a descriptive cross-sectional design. An inclusive sample was drawn from adults in the DOTS programme receiving first line treatment during the 6-month period prior to commencement of the research. The calculated sample size was 234 individuals. The data collection tools included a questionnaire, 2-day recall and 30-day recall instruments and pill counts. Data were analysed using EPI info version 7 which included descriptive statistics to measure level of adherence. Associations between identified factors and adherence to TB treatment were also determined. Results: The final sample size was 80 participants of which 76% were male. The mean composite adherence rate was found to be 94% while the proportion of the patients who achieved adherence of 95% and above was 75%. Identified barriers to adherence include forgetfulness, lack of transport fare on clinic appointment days, patients not feeling well and so were not strong enough to attend clinic appointments. On the other hand, the role of treatment supporters and counseling were found to have a positive impact on adherence to DOT in this setting. The use of reminders such as cell phones and alarm-radios were also identified as facilitators to adherence. Patients' knowledge of consequences for not taking medications as prescribed, which is closely linked with counseling, was found to be significantly associated with adherence in this study. Education status of participants was found to be significantly associated with adherence to DOTS (p = 0.01), when considering the pharmacy refill pill count as the adherence measure. Significant association was found between DOTS treatment regimens and 30-day recall adherence measures (p = 0.002). Significant association was also found for medication side effects and the adherence measures of 2-day recall, 30-day recall and pill count with p = 0.04; p = 0.03; p = 0.05 respectively There were significant associations between age and adherence with two of the adherence measures (30-day recall and pill count) at p = 0.002 and p = 0.003 level of significance respectively. Significant association was observed between duration of DOTS treatment when dichotomised using the mean treatment period (17 weeks) as the cut-off point and any of the adherence measures. Conclusion: The factors identified in this study can be classified into patient related factors, economic factors, social factors and health care workers and health system related factors. Furthermore, the factors at these different levels impact on one another and their improvements need to be made at all these levels to address the challenges facing TB patients to achieve optimal treatment adherence. This study is the first study of its kind in the study location and the findings have provided useful baseline data on the adherence rates and some insights into the major factors that affect adherence among patients on DOTS at a Pretoria West District Hospital. However further qualitative and quantitative studies are required to explore the factors influencing adherence further.

Factors associated with the development of drug resistant tuberculosis in EthiopiaHenock Bekele Keto 01 1900 (has links)
PURPOSE: The purpose of this study was to assess factors associated with the development of drug resistant tuberculosis in Ethiopia.
DESIGN: A quantitative case-control study was conducted to determine if there were any significant differences in prevalence of pre-defined factors between cases and controls.
METHODS: Cases were patients with drug resistant tuberculosis who had a confirmed diagnosis by culture drug-susceptibility or gene expert tests. Successfully treated, tuberculosis symptom free patients who had been on first-line tuberculosis treatment and who were registered as cured or treatment completed were taken as controls. An equal number of cases (N=181) and controls (N=181) was selected using a systematic random sampling method and was used in the study. A structured questionnaire developed by the researcher was used to collect data. Odds ratio and multiple logistic regression were used to quantify the strength of association between dependent and independent variables.
RESULTS: The development of drug resistant tuberculosis was significantly associated with two or more previous episodes of tuberculosis illness (adjusted odds ratio (AOR): 14.84; 95% CI 8.90 –24.75), previous first-line tuberculosis treatment not directly observed by a health worker for 7 to 8 weeks (AOR: 13.41; 95% CI 8.06 – 22.29) and previous first-line tuberculosis treatment outcome of failure (AOR: 39.19; 95% CI 12.05 -127.46). Interruption of first-line tuberculosis treatment for one day or more (AOR = 4.28; 95% CI 2.76 – 6.64) and history of treatment in the first-line tuberculosis treatment category for previously treated patients (AOR: 3.70; 95% CI 2.40 – 5.72) were also significantly associated with the development of drug resistant tuberculosis in the current study.
CONCLUSION: Patients with a history of previous first-line tuberculosis treatment, patients who interrupted previous first-line tuberculosis treatment and patients with previous first-line tuberculosis treatment outcome of failure were at high risk of developing drug resistant tuberculosis. Therefore, the full course of first-line tuberculosis treatment should be given, following the Directly Observed Treatment (DOT) guide. Patients with recurrent tuberculosis and unfavourable first-line tuberculosis treatment outcome should be tested for drug susceptibility. / Health Studies / D. Litt. et Phil. (Health Studies)
