Determinants of adherence to tuberculosis therapy among patients receiving Directly Observed Treatment from a district hospital in Pretoria, South Africa

Aiyegoro, 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 Ethiopia

Henock 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)

A transferência da política do tratamento diretamente observado em diferentes níveis de gestão para o controle da tuberculose / Policy Transfer of the Directly Observed Treatment at Different Levels of Management for Tuberculosis Control

Assis, Elisangela Gisele de 15 January 2016 (has links)
Trata-se de estudo qualitativo desenvolvido por meio de análise de discurso cujo objetivo foi analisar a discursividade dos gestores em diferentes níveis de gestão sobre transferência da política do tratamento diretamente observado (TDO) no controle da tuberculose. Para isto, esta análise parte do contexto de decisão macropolítico para o contexto micropolítico tendo como cenário local o município de Ribeirão Preto-SP, considerado prioritário para o controle da doença. Foram entrevistados quatro sujeitos-gestores envolvidos com a política do TDO nas instâncias estadual, regional, municipal e no nível intermediário entre a regional e o município, mediante aceite de termo de compromisso. Os dados foram coletados no período de agosto a dezembro de 2013, as entrevistas foram audiogravadas, transcritas, respeitando-a na sua íntegra. O corpus da pesquisa foi composto por recortes, formação discursiva e marcas linguísticas, quais foram selecionados dos discursos dos sujeitos. A análise ocorreu mediante a fundamentação teórico-metodológica da Análise de Discurso (AD) de matriz francesa, que se sustenta sobre três vertentes teóricas: o Materialismo Histórico, a Linguística e a Psicanálise. Este tipo de análise não visa uma análise exaustiva horizontal ou de toda extensão do objeto de pesquisa, por entender que este não se esgota e que um discurso institui-se sempre em relação aos outros. Busca-se apoiar na exaustividade vertical com o intuito de contemplar o objetivo do trabalho e da temática abordada. Os dados foram organizados sob o eixo da temática da transferência de políticas e da temática da TB os quais apontaram para diferentes efeitos de sentido durante a transferência da política do TDO como o silenciamento, apagamento, polifonia, polissemia e contradição durante o processo de transferência desta política nos diferentes níveis de gestão, que passou gradativamente pelo processo de transferência autoritária para a transferência voluntária da maior instancia política para a menor. Destaca-se que no município este processo ocorreu de forma incompleta visto que não houve a superação do paradigma da desconcentração das ações de TB para a Atenção Primária em Saúde (APS) / This qualitative study was conducted using discourse analysis, the objective of which was analyzed the reports of different level managers regarding policy transfer of Directly Observed Treatment (DOT) in the control of tuberculosis. This analysis starts with the context of macro-political decisions in the micro-political context and the local setting was the city of Ribeirão Preto, SP, Brazil, considered a priority in the control of the disease. Four managers involved with the DOT policy at the state, regional, and city levels and another manager in the intermediate level between region and city were interviewed after signing consent forms. Data were collected from August to December 2013. The interviews were recorded, transcribed, respecting it in its entirety. The study\'s corpus was composed of excerpts, discursive formations and linguistics marks, which were selected from the participants\' reports according to the guiding question. Analysis was based on the French theoretical-methodological framework of Discourse Analysis, which in turn is grounded on three theoretical aspects: the Historical Materialism, Linguistics and Psychoanalysis. An exhaustive horizontal analysis, or an analysis that encompasses the entire extent of the research\'s object, is not intended in this type of analysis because the topic is not exhausted and discourses are always instituted in relation to others. The objective is to be supported in vertical exhaustiveness to contemplate the objective of the study and the topic under study. Data were organized under policy transfer\' and tuberculosis\' thematic axis, which indicate different effects of meanings during DOT policy transfer, such as muting, blanking, polyphony, polysemy, and contradictions during this policy transfer process at the different levels of management, which gradually moved from an authoritative transfer to a voluntary transfer, from a higher political instance to a lower one. Nonetheless, this process was not completed in the city because the paradigm decentralizing TB actions from Primary Health Care (PHC) was not overcome

Factors affecting the uptake of community TB care in Lobatse district of Botswana as experienced by patients

Rankosha, Omphemetse 03 June 2015 (has links)
The study aimed to assess factors affecting the uptake of community-based Tuberculosis care (CTBC) as experienced by patients in Lobatse in order to make recommendations to enhance the uptake of CBTC in this area. A cross-sectional study was conducted, using structured interviews amongst 101 TB patients in Lobatse who registered for directly observed treatment (DOT) for TB in the GOB’s health facilities from January 2011 to August 2013. The SPSS (version 21) was used to analyse the data. Univariate logistic regression models were used. Participation in CTBC was an outcome. The main predictors for participation in CBTC included, knowledge and attitudes towards CTBC (p=0.0003), perceived barriers and enablers towards this programme (p=0.0279), and patient satisfaction with this programme (p=0.0315). The research findings pertain to TB services in Lobatse, because the study was conducted in government health facilities implementing the Botswana National Tuberculosis Programme (BNTP) CTBC guidelines only in Lobatse / Health Studies / M.A. (Public Health)

Διαχείριση της φυματίωσης στην πρωτοβάθμια περίθαλψη

Τσίρος, Γεώργιος 07 April 2011 (has links)
Η φυματίωση είναι λοιμώδης νόσος μεταδιδόμενη αερογενώς και προκαλούμενη από βακτήρια τα οποία ανήκουν στην ομάδα των Μυκοβακτηριδίων και ιδιαίτερα στο σύμπλοκο της φυματιώσεως (Mycobacterium tuberculosis complex). Τα τελευταία χρόνια αποτελεί ένα επιδεινούμενο πρόβλημα δημόσιας υγείας ανά την υφήλιο, με επίπτωση παγκοσμίως για το 2007 139/100.000 πληθυσμό, ενώ για την Ευρώπη 54/100.000 και για την Ελλάδα 5,9/100.000 πληθυσμό. Η σωστή καταγραφή των κρουσμάτων, συμβάλλει στην πραγματική αποτύπωση του μεγέθους του προβλήματος και των χαρακτηριστικών της νόσου και θα οδηγήσει σε αποτελεσματικές θεραπευτικές παρεμβάσεις, ώστε να επιτευχθούν και στη χώρα μας οι στόχοι που έχει θέσει η ΠΟΥ, δηλαδή ο περιορισμός κατά το ήμισυ της νοσηρότητας και των θανάτων από φυματίωση έως το 1015, συγκριτικά με το 1990 και η εκρίζωση της νόσου έως το 2050. Στην παρούσα μελέτη έγιναν αρχικά δύο επιδημιολογικές έρευνες που αφορούσαν: α) την επιδημιολογία της φυματίωσης στη Δυτική Ελλάδα και την αξιολόγηση της πληρότητας των υποχρεωτικών δηλώσεων (2000-2003) καθώς και β) την εκτίμηση του δείκτη διαμόλυνσης σε μαθητικό πληθυσμό του Νομού Ηλείας (1994-2000). Σκοπός μας ήταν να περιγραφεί και να αναλυθεί η επιδημιολογία της φυματίωσης στη Δυτική Ελλάδα (Νομοί Ηλείας, Αχαΐας, Αιτωλοακαρνανίας), ώστε να εξετασθεί η επάρκεια ολόκληρου του συστήματος επιτήρησης και ελέγχου για τη δηλωτέα αυτή νόσο στο ΚΕΕΛΠΝΟ, καθώς και να αξιολογηθεί η εξέλιξη του δείκτη διαμόλυνσης της φυματίωσης στο νομό Ηλείας, στα πλαίσια πρόληψης της νόσου. Για τον λόγο αυτό, χρησιμοποιήθηκαν επίσημα στοιχεία από την ΠΟΥ, το ΚΕΕΛΠΝΟ, τις Νομαρχιακές αυτοδιοικήσεις, αλλά και αρχεία των νοσοκομείων ENΝΘΔΕ, του ΠΓΝ Πατρών, καθώς και του Κέντρου Υγείας Γαστούνης. Εν συνεχεία, μελετήθηκε η εφαρμογή της Άμεσα Επιτηρούμενης Θεραπείας (DOTS) σε 13 νεοδιαγνωσθέντες ασθενείς με φυματίωση, συγκριτικά με την έκβαση 41 πρώην διαγνωσθέντων ασθενών (μάρτυρες) χωρίς ΑΕΘ, αλλά με την έως τώρα συντηρητική αντιμετώπιση, όλοι κάτοικοι του Νομού Ηλείας. Για την ολοκλήρωση της μελέτης υπήρξε συνεργασία του Πνευμονολογικού Ιατρείου του Γ.Ν. Πύργου με τον ειδικά εκπαιδευμένο Γενικό/Οικογενειακό Ιατρό, ο οποίος πραγματοποιούσε τις κατ΄ οίκον επισκέψεις και προσωπικές συνεντεύξεις στους νέους ασθενείς, στους μάρτυρες αλλά και στα μέλη των οικογένειών τους. Για την στατιστική ανάλυση των αποτελεσμάτων μας, χρησιμοποιήθηκε το πρόγραμμα SPSS (11,0 – 15,0). Από επιδημιολογικές μελέτες προκύπτει ότι οι χώρες της Ευρωπαϊκής Ένωσης παρουσιάζουν μια σταθερή μείωση του μέσου όρου επίπτωσης της φυματίωσης το διάστημα 1986-2006, με την Ελλάδα να έχει τις μικρότερες τιμές (4,7/100.000 το 2001 και 6/100.000 το 2007). Με βάση όμως «ενδεικτικές» επιδημιολογικές μελέτες-έρευνες της φυματίωσης στον Ελλαδικό χώρο σε αντίστοιχα διαστήματα, προκύπτει διακύμανση της επίπτωσης από 16 – 73/100.000. Αναφορικά με την έρευνά μας στη Δυτική Ελλάδα, η μέση ετήσια επίπτωση βρέθηκε να είναι 5,4 ανά 100.000 άτομα (4 Αχαΐα, 6 Αιτωλοακαρνανία, 7,2 Ηλεία), ενώ τα επίσημα στοιχεία από το ΚΕΕΛΠΝΟ παρουσιάζουν μόνο 3,8 κρούσματα ανά 100.000 πληθυσμό. Στην μελέτη μυκοβακτηριδιακής διαμόλυνσης για τον μαθητικό πληθυσμό του νομού Ηλείας, συγκρίνοντας τις δύο τριετίες 1994-1996 και 1998-2000, ο Μ.Ο. εξάπλωσης του ΔΜΔ για τους μαθητές του Δημοτικού μειώθηκε από 0,7% σε 0,16%, ενώ στους μαθητές του Γυμνασίου παρατηρήθηκε μια μικρή πτώση, από 2,51% σε 2,41%. Σε επίπεδο γειτονικών νομών (αλλά και αναπτυγμένων χωρών), ο μέσος φυματινικός δείκτης είναι <1%, ενώ ως εκρίζωση κατά την Π.Ο.Υ. νοείται ο περιορισμός του Δ.Δ.<0,1%. Με βάση τις διεθνείς οδηγίες, η θεραπευτική αντιφυματική αγωγή αποτελείται από INH, RIF, PZA και EMB για 2 μήνες και για τους επόμενους 4 μήνες χορηγούνται μόνο INH και RIF. Κατόπιν αξιολόγησης των αποτελεσμάτων της προοπτικής μας μελέτης υπό το πρόγραμμα DOTS, προκύπτει ότι τα ποσοστά επιτυχούς θεραπείας ήταν 84,6% (προσεγγίζοντας το κατώτερο 85% που έχει θέσει ο WHO), εκ των οποίων 69,2% είχαν αρνητικά πτύελα στο τέλος της θεραπείας και 15,4% ολοκλήρωσαν την θεραπεία χωρίς μικροβιολογική εξέταση πτυέλων (2 αθίγγανοι που δε συνεργάστηκαν). Αξίζει να σημειωθεί, ότι ένας ασθενής απεβίωσε και ένας εξαφανίστηκε, λόγω αλλαγής πόλης στην οποία εργαζόταν. Αντίθετα, για τους μάρτυρες μόνο το 75,6% επιβεβαιώνουν αποτελεσματικότητα της θεραπείας, το 49% έλαβε 9μηνη αντιφυματική αγωγή και το 36% 12μηνη. Η σημαντικότητα της κατ’ οίκον επιτηρούμενης θεραπείας, πέραν της επιτυχούς θεραπείας των ασθενών, παρουσιάζει οφέλη και για τα μέλη. Πριν την κατ’ οίκον επίσκεψη δεν είχε γίνει η διενέργεια Mantoux στο 43,3%, από τα μέλη των ασθενών, στους οποίους και έγινε κατά την επίσκεψη στις οικίες τους από το Γενικό Ιατρό. Αντίθετα, το ήμισυ από τα μέλη των οικογενειών των μαρτύρων, κατά την διάγνωση του ασθενούς τους, δεν προσήλθαν στο νοσοκομείο για διενέργεια Mantoux. Μετά τις επισκέψεις στις οικίες από τον Γενικό Ιατρό, τηρήθηκε απόλυτα η εφαρμογή των μέτρων πρόληψης και συνθηκών διαβίωσης (αερισμός, φωτεινότητα, καθαριότητα, συγχρωτισμός, κ.τ.λ.) στα μέλη των ασθενών. Στα δε μέλη των μαρτύρων ούτε εκεί εφαρμόζονταν σωστά (92,3%) μέτρα πρόληψης – προφύλαξης και αυτό συνέβη καθ’ όλη την διάρκεια θεραπείας του ασθενούς. Σχετικά με τη νοσηρότητα των μελών, από τους 30 συγγενείς – μέλη των ασθενών, οι 4 (13,3%) χρειάστηκαν χημειοπροφύλαξη, ενώ από τους 111 συγγενείς – μέλη των μαρτύρων, οι 14 (12,6%) χρειάστηκαν χημειοπροφύλαξη και οι 7 (6,3%) νόσησαν και έλαβαν θεραπεία. Συμπερασματικά, η σωστή αντιμετώπιση του προβλήματος δεν έγκειται μόνο στην έγκαιρη διάγνωση και θεραπεία, αλλά και στην αξιόπιστη καταγραφή των κρουσμάτων που θα μας ευαισθητοποιήσουν στο να αντιληφθούμε την πραγματικά ανησυχητική διάσταση του προβλήματος και να χρησιμοποιήσουμε αποτελεσματικότερους τρόπους πρόληψης και αντιμετώπισης. Για την πληρέστερη δήλωση των κρουσμάτων, θα πρέπει να υπάρχει ευαισθητοποίηση και ένα εύκολο και προσιτό δίκτυο επικοινωνίας μεταξύ του ΚΕΕΛΠΝΟ, των Νοσοκομειακών αλλά και των ιδιωτών ιατρών, των Κ.Υ. αλλά και των Νομαρχιακών Αυτοδιοικήσεων, προκειμένου να κατανοηθεί επακριβώς ο τρόπος καταγραφής και αποστολής των στοιχείων, κατόπιν διάγνωσης των κρουσμάτων. Η άμεσα επιτηρούμενη θεραπεία, στοχεύει όχι μόνο στη σωστή παρακολούθηση και ίαση των ασθενών με φυματίωση, αλλά και στην εκπαίδευση των μελών των οικογενειών τους σε θέματα πρόληψης και βελτίωσης των επιβαρυντικών παραγόντων διαβίωσης, μειώνοντας σημαντικά τη νοσηρότητα του πληθυσμού. / Tuberculosis is an infectious disease transmitted aerogen and caused by bacteria which belong to the Mycobacterium tuberculosis complex. In the past few years it constitutes an increasing problem of public health with a worldwide incidence rate of 139/100 000 population in the year 2007, while in Europe the incidence was 54 and in Greece 5.9, respectively. The accurate recording of cases contributes to the actual mapping of the burden of the disease leading thus to focused therapeutic interventions, which can be also achieved in our country, according to the goals set by WHO, i.e. the decrease of morbidity and mortality from tuberculosis at least the half until 2015, in comparison to 1990 and the eradication of the disease until 2050. In the present research two epidemiologic studies were carried out, concerning a) the epidemiology of tuberculosis in Western Greece and the evaluation of completeness of TB notifications (2000-2003), b) the estimation of tuberculin status in school population in the Prefecture of Ilia (1994-2000). The aim of the studies was to described and analyze the epidemiological characteristics of tuberculosis in Europe in comparison to Greece, to describe and analyze the epidemiology of tuberculosis in Western Greece (Prefectures Ilia, Achaia, Etoloakarnania) and to evaluate the completeness of TB notifications in order to examine the effectiveness of the surveillance system and the effectiveness of disease control and prevention, as well as to evaluate the tuberculin status in the prefecture of Ilia, in order to examine if satisfactory progress has been achieved in the control and prevention of tuberculosis. For these purposes, official data of WHO, KEELPNO (Hellenic Centre of Disease Control), the local and prefectoral self-administrations were used, as well as records of the hospitals in the examined area and of the Health Centre of Gastouni. Furthermore, a study was carried out, implementing a Directly Observed Treatment Short Course (DOTS) programme in the prefecture of Ilia (Western Greece) and assessing the efficacy of the WHO-recommended strategy in 13 newly detected pulmonary tuberculosis cases in comparison to 41 TB cases managed conventionally. In collaboration with the clinic of pulmonology of the general hospital of Pyrgos a general practitioner who was educated in DOTS strategy carried out home visits and completed a questionnaire in a face-to-face interview with the newly diagnosed patients, the past treated patients as well as the household members of the patients. All statistical analyses were performed using SPSS for Windows (v.11.0 – v.15.0). According to the results of the epidemiological studies, the countries of the European Union present a steady decline of the average incidence of tuberculosis (<20/100 000), with Greece presenting the lowest rates (4.7/100 000, 2001). Based on other “indicative” epidemiological studies carried out in Greece, the incidence of tuberculosis varies from 16 – 73, respectively. In regard to the study performed in Western Greece, the mean annual incidence was found to be 5.4 (4 in Achaia, 6 in Etoloakarnania and 7.2 in Ilia), respectively, while the official data from KEELPNO for Western Greece revealed only 3.8 cases per 100 000 population. Finally, for the school population in the prefecture of Ilia, comparing the two three-year periods from 1994-1996 and 1998-2000, the mean prevalence of positive tuberculin status in the primary schoolchildren declined from 0.7% to 0.16%, while in the secondary schoolchildren we observed a very small decline, from 2.51% to 2.41%. In the neighboring prefectures (but also in developed countries), the mean prevalence of positive tuberculin status is <1%, while as indicator for eradication WHO determine a positive tuberculin status<0.1%. Based on the international guidelines, the antituberculosis therapy comprises INH, RIF, PZA and EMB for 2 months and for the following next 4 months only INH and RIF are taking. The evaluation of the results of the prospective DOTS study shows treatment success in 84.6% (approximating the lower limit of 85% set by the WHO), out of them 69.2% had negative saliva swab test at the end of treatment and 15.4% completed the treatment without microbiological examination of the saliva (2 gypsies who showed non compliance). One case under DOTS programme died during the study and one was lost to follow-up, because of change of residence. On the contrary, among the past treated cases 75.6% confirmed treatment effectiveness, in 49% after 9 month therapy duration and in the 36% after 12, respectively. The importance of the Directly Observed Treatment Short Course, beyond the successful treatment of patients, presents benefits also for the household members. Before the 1st home visit, Mantoux test was not carried out in 43.3% of the household members, but performed in all members during the 1st home visit by the general practitioner. On the contrary, 50% of the household members of the past treated patients had not carried out Mantoux test after diagnosis confirmation in the past treated patients, since they did not visit the hospital/health center for vaccination. After the doctor’s home visits, the family members adhered to the preventive measures and adequate living conditions (airing, brightness, cleanness, etc.). In the members of past treated patients the preventive measures were not met in 92.3% during the whole treatment period. With regard to the morbidity of the members of DOTS patients, from the 30 household members 4 (13.3%) needed chemoprophylaxis, while from the 111 members of past treated patients, 14 (12.6%) needed chemoprophylaxis and 7 (6.3%) antituberculosis treatment. In conclusion, the adequate confrontation of the problem does not lie only in the early diagnosis and treatment of TB, but also in the reliable notification of cases, in order to create public awareness of the burden and to implement more effective control and prevention measures. For optimal monitoring a more accurate and to all accessible communication network with proper and sincere co-operation between all actors (KEELPNO, hospitals, doctors in private praxis, health centers and prefectoral self-governments) is needed, in order to improve the accuracy of the notification system. The Directly Observed Treatment Short Course aims not only in the appropriate control and cure of the TB patients, but also in the education of the household members, in regard to prevention and improvement of aggravating risk factors, decreasing thus considerably the burden of the disease.

Teixeira, Carolina Dulce Songo 11 1900 (has links)
The purpose of this study is to explore and describe the knowledge, attitudes and experiences of health care workers who care for patients receiving treatment under DOTS strategy at public health facilities in the Windhoek District of the Khomas Region. A qualitative explorative, descriptive and contextual research design was used in this study. A purposive sampling was used to select participants who met the inclusion criteria for the study. The inclusion criteria was to be a health care worker who at the time of the study was working with patients who are on DOT for at least 6 months. A semi-structured interview guide was used to collect data. The study was conducted in the Windhoek district of the Khomas region, with a sample of 14 health care workers. Data was analysed by means of content analysis, a process of organizing and integrating narrative, qualitative data according to emerging themes and concepts. The three themes, which emerged from data analysis, were the knowledge of health care workers regarding the implementation of DOTS, the attitudes of health care workers towards patients on DOT which may affect the success of their treatments, and the experiences of health care workers when attending to patients on DOTS. The findings from the study may be used to engage stakeholders to address the shortcomings that exist in the implementation of the DOTS strategy in the district. / Health Studies / M.A. (Nursing Science)

Evaluation of directly observed tuberculosis treatment strategy in Ethiopia : patient centeredness and satisfaction

Woldeyes, Belete Getahun 06 1900 (has links)
Text in English with questionnaire in Amharic / Purpose: The purpose of the study was to evaluate the effectiveness of the tuberculosis directly observed treatment, short-course (DOTS) strategy with respect to patient centeredness and satisfaction, and propose a model in support of the DOTS strategy in Addis Ababa, Ethiopia. Method: The study was conducted in Addis Ababa, Ethiopia using a mixed-method approach. An interviewer-administered questionnaire was used to collect quantitative data from 601 randomly selected TB patients who were on TB treatment followup in 30 health facilities.Three focus group discussions were conducted with 23 TB experts purposefully selected from 10 sub-city health offices and health bureau. Moreover, telephonic interviews were conducted with 25 defaulted TB patients who had been attending TB treatment in the health facilities. The quantitative data were described using mean, median, percentage and frequencies. Logistic regression and exploratory factor analysis were used to extract associated factors using SPSS version 21 software. Thematic analysis was used for qualitative data analysis. Deductive and inductive reasoning was used to propose a descriptive model with substantiating literatures. Findings: Of the 601 TB patients included, 40% of them perceived they had not received a patient-centred TB care (PC-TB care) with DOTS strategy. Gender (AOR=0.45, 95%CI 0.3, 0.7), good communication (AOR=3.2, 95%CI 1.6, 6.1), treatment supporter (AOR=3.4, 95%CI 2.1, 5.5) were associated with the perceived PC-TB care. Thirty-seven percent of TB patients were following their TB treatment with feeling of dissatisfaction with DOTS strategy. Gender (AOR=2.2; 95%CI 1.3, 3.57), place of residence (AOR=3.4; 95%CI 1.6, 7.6), presence of symptoms (AOR=0.6, 95%CI 0.40, 0.94) and treatment-supporter (AOR=4.3, 95%CI 2.7, 6.8) were associated with satisfaction of TB patients. TB experts and defaulted TB patients pointed out that DOTS strategy is not providing comprehensive PC-TB care except the provision of facility choice where to follow during initiation of the treatment. DOTS delivery system inflexibility, loose integration, HCPs’ characteristic, communication skill and motivation and the community awareness were explored factor with patient centeredness of DOTS. DOTS delivery system, incompatible of diagnosis and patient beliefs were the identified categories to default. The proposed PC-TB care model core constructs are patient, community, health care providers, health care organisation and TB care delivery system. The core constructs are directed by policy and monitoring and evaluation components. Conclusion: DOTS strategy is limited to provide fully integrated PC-TB care and did not provide full satisfaction to TB patients. Therefore, a support that makes the TB care patient-centred are important and the proposed PC-TB care model needs to be tested, practiced and evaluated for its performance toward increments of patient centeredness of TB care. / Health Studies / D.Litt. et Phil.
