The impact of intensified supervisory activities on tuberculosis treatment

Explaining the successes and failures of tuberculosis treatment programs; a tale of two regions in rural eastern Uganda

Background

Optimally performing tuberculosis (TB) programs are characterized by treatment success rate (TSR) of at least 90%. In rural eastern Uganda, and elsewhere in sub Saharan Africa, TSR varies considerably across district TB programs and the reasons for the differences are unclear. This study explored factors associated with the low and high TSR across four districts in rural eastern Uganda.

Methods

We interviewed District TB and Leprosy Supervisors, Laboratory focal persons, and health facility TB focal persons from four districts in eastern Uganda as key informants. Interviews were audio recorded, transcribed verbatim, and imported into ATLAs.ti where thematic content analysis was performed and results were summarized into themes.

Results

The emerging themes were categorized as either facilitators of or barriers to treatment success. The emerging facilitators prevailing in the districts with high rates of treatment success were using data to make decisions and design interventions, continuous quality improvement, capacity building, and prioritization of better management of people with TB. The barriers common in districts with low rates of treatment success included lack of motivated and dedicated TB focal persons, scarce or no funding for implementing TB activities, and a poor implementation of community-based directly observed therapy short course.

Conclusion

This study shows that several factors are associated with the differing rates of treatment success in rural eastern Uganda. These factors should be the focus for TB control programs in Uganda and similar settings in order to improve rates of treatment success.

A systematic review of non-pharmacological interventions to improve therapeutic adherence in tuberculosis

BACKGROUND

Reviews examining non-pharmacological interventions to improve therapeutic adherence in tuberculosis have several limitations (design, quality assessment…). Consequently, for clinical practice, it is important to generate a review containing all the information to improve patient adherence, solving the previous issues.

OBJECTIVES

To examine non-pharmacological interventions to improve therapeutic adherence in tuberculosis through clinical trials.

METHODS

A systematic review in MEDLINE/EMBASE was performed.

RESULTS

Thirty seven papers were analysed. The disease treatment interventions were disparate, grouped into: education, psychological interventions, new technologies, directly observed treatment, incentives and improved access to health services. In the treatment of latent infection, the majority of studies were conducted in the marginal population (drug addicts, homeless individuals and prisoners) and were based mainly on the provision of incentives. Study quality was generally low.

CONCLUSIONS

Great variability exists in the studies comparing strategies for identifying interventions, objectives and effects. The designs carried out generally have methodological deficits.

Reminder systems to improve patient adherence to tuberculosis clinic appointments for diagnosis and treatment

BACKGROUND

People with active tuberculosis (TB) require six months of treatment. Some people find it difficult to complete treatment, and there are several approaches to help ensure completion. One such system relies on reminders, where the health system prompts patients to attend for appointments on time, or re-engages people who have missed or defaulted on a scheduled appointment.

OBJECTIVES

To assess the effects of reminder systems on improving attendance at TB diagnosis, prophylaxis, and treatment clinic appointments, and their effects on TB treatment outcomes.

SEARCH METHODS

We searched the Cochrane Infectious Diseases Group Specialized Register, Cochrane Effective Practice and Organization of Care Group Specialized Register, CENTRAL, MEDLINE, EMBASE, LILACS, CINAHL, SCI-EXPANDED, SSCI, mRCT, and the Indian Journal of Tuberculosis without language restriction up to 29 August 2014. We also checked reference lists and contacted researchers working in the field.

SELECTION CRITERIA

Randomized controlled trials (RCTs), including cluster RCTs and quasi-RCTs, and controlled before-and-after studies comparing reminder systems with no reminders or an alternative reminder system for people with scheduled appointments for TB diagnosis, prophylaxis, or treatment.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risk of bias in the included trials. We compared the effects of interventions by using risk ratios (RR) and presented RRs with 95% confidence intervals (CIs). Also we assessed the quality of evidence using the GRADE approach.

MAIN RESULTS

Nine trials, including 4654 participants, met our inclusion criteria. Five trials evaluated appointment reminders for people on treatment for active TB, two for people on prophylaxis for latent TB, and four for people undergoing TB screening using skin tests. We classified the interventions into 'pre-appointment' reminders (telephone calls or letters prior to a scheduled appointment) or 'default' reminders (telephone calls, letters, or home visits to people who had missed an appointment).For people being treated for active TB, clinic attendance and TB treatment completion were higher in people receiving pre-appointment reminder phone-calls (clinic attendance: 66% versus 50%; RR 1.32, 95% CI 1.10 to 1.59, one trial (USA), 615 participants, low quality evidence; TB treatment completion: 100% versus 88%; RR 1.14, 95% CI 1.02 to 1.27, one trial (Thailand), 92 participants, low quality evidence). Clinic attendance and TB treatment completion were also higher with default reminders (letters or home visits) (clinic attendance: 52% versus 10%; RR 5.04, 95% CI 1.61 to 15.78, one trial (India), 52 participants, low quality evidence; treatment completion: RR 1.17, 95% CI 1.11 to 1.24, two trials (Iraq and India), 680 participants, moderate quality evidence).For people on TB prophylaxis, clinic attendance was higher with a policy of pre-appointment phone-calls (63% versus 48%; RR 1.30, 95% CI 1.07 to 1.59, one trial (USA), 536 participants); and attendance at the final clinic was higher with regular three-monthly phone-calls or nurse visits (93% versus 65%, one trial (Spain), 318 participants).For people undergoing screening for TB, three trials of pre-appointment phone-calls found little or no effect on the proportion of people returning to clinic for the result of their skin test (three trials, 1189 participants, low quality evidence), and two trials found little or no effect with take home reminder cards (two trials, 711 participants). All four trials were conducted among healthy volunteers in the USA.

AUTHORS' CONCLUSIONS

Policies of sending reminders to people pre-appointment, and contacting people who miss appointments, seem sensible additions to any TB programme, and the limited evidence available suggests they have small but potentially important benefits. Future studies of modern technologies such as short message service (SMS) reminders would be useful, particularly in low-resource settings.

Strategies to Promote Adherence to Treatment by Pulmonary Tuberculosis Patients: A systematic review

BACKGROUND

Successful tuberculosis control depends upon effective treatment of patients which requires adherence throughout the full course of medical treatment. Poor adherence to treatment is a major obstacle in the global fight against tuberculosis. Therefore, interventions that promote adherence to the tuberculosis treatment regimen should be implemented.

OBJECTIVE

To review and synthesise the best available research evidence that investigates the effectiveness of strategies to promote adherence to treatment by patients with pulmonary tuberculosis.

INCLUSION CRITERIA

This review considered all studies that included adults aged ≥ 15 years diagnosed with smear positive and smear negative pulmonary tuberculosis (regardless of HIV infection) in community settings who had never received anti-tuberculosis drugs, or had taken them for less than one month.Intervention included strategies to promote adherence to tuberculosis treatment by patients with pulmonary tuberculosis.Outcomes included measures for treatment completion rate, cure rate, and success rate.The review primarily considered any randomised controlled trials that explored different strategies to promote adherence to tuberculosis treatment of patients with pulmonary tuberculosis but also included quasi-experimental studies.

SEARCH STRATEGY

The search sought to find published and unpublished studies. The time period of the search covered articles published from 1990 to 2010 in English and Thai language. The database searches included: CINAHL, EMBASE, Cochrane Library, PubMed, Science Direct, Current Content Connect, Thai Nursing Research Database, Thai thesis database, Digital Library of Thailand Research Fund, Research of National Research Council of Thailand, and Database of Office of Higher Education Commission. Studies were additionally identified from reference lists of all studies retrieved.

METHODOLOGICAL QUALITY

Studies selected for retrieval were assessed by two independent reviewers for methodological quality using a standardised critical appraisal tool from the Joanna Briggs Institute.

DATA COLLECTION

Data extraction was performed using a standardised data extraction form from the Joanna Briggs Institute.

DATA SYNTHESIS

The quantitative study results were pooled in statistical meta-analysis using the Review Manager software (RevMan 5.0) and summarised in narrative form where statistical pooling was not appropriate or possible.

RESULTS

This systematic review included ten randomised controlled trials and eight quasi-experimental studies that report on the effectiveness of a number of specific interventions to improve adherence to tuberculosis treatment among newly diagnosed pulmonary tuberculosis patients. These interventions included Directly Observed Treatment coupled with alternative patient supervision options, case management with Directly Observed Treatment, Short-course, the intensive triad-model program, and an intervention package consisting of improving patients' counselling and communication, decentralisation of treatment, patient choice of Directly Observed Treatment supporter, and reinforcement of supervision activities.

CONCLUSION

The interventions that had the best outcomes for treatment adherence among newly diagnosed pulmonary tuberculosis patients were Directly Observed Treatment and Directly Observed Treatment, Short-course combined with case management, improving counselling and communication and decentralisation of treatment. These interventions should be implemented by health care providers and tailored to local contexts and circumstances, where appropriate.It would be beneficial to shift the treatment of all pulmonary tuberculosis patients to facilities within the primary health care structure. Directly Observed Treatment coupled with alternative patient supervision options, formalised educational programs and a tuberculosis case management team should be used to improve adherence to tuberculosis treatment among newly diagnosed pulmonary tuberculosis patients.Our review shows the need for further large-scale on adherence to treatment by newly diagnosed pulmonary tuberculosis patients. Factors that determine the usefulness of Directly Observed Treatment in various settings require further study. Further strategies, especially those that are feasible in developing countries or countries with limited resources, should be evaluated in randomised controlled trials before being introduced into routine practice.

Managerial supervision to improve primary health care in low- and middle-income countries

BACKGROUND

Primary healthcare (PHC) workers often work alone or in isolation. Healthcare managerial supervision is recommended to help assure quality; but this requires skilled supervisors and takes time and resources. It is therefore important to assess to what extent supervision is beneficial and the ways in which it can be implemented.

OBJECTIVES

To review the effects of managerial supervision of health workers to improve the quality of PHC (such as adherence to guidance or coverage of services) in low- and middle-income countries.

SEARCH STRATEGY

We searched The Cochrane Central Register of Controlled Trials (CENTRAL) 2011, Issue 1, part of The Cochrane Library. www.thecochranelibrary.com, including the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register (searched 10 March 2011); MEDLINE, Ovid 1950 to March Week 1 2011 (searched 08 March 2011); EMBASE, Ovid 1980 to 2011 Week 12 (searched 08 March 2011); CINAHL, Ebsco 1981 - present (searched 10 March 2011); LILACS, VHL (searched 10 March 2011).

SELECTION CRITERIA

Randomised controlled trials, controlled before-and-after studies, and interrupted time series studies, conducted in PHC in low- and middle-income countries. Supervision includes site visits from a central level of the health system, plus at least one supervisory activity. We excluded studies aimed solely at improving the clinical skills of PHC workers.

DATA COLLECTION AND ANALYSIS

We extracted data using a predefined form and assessed for risk of bias using the EPOC risk of bias criteria. Data are presented in a narrative way without pooling the effects on the outcomes as studies and outcomes were diverse.

MAIN RESULTS

Nine studies met the inclusion criteria: three compared supervision with no supervision, five compared enhanced supervision with routine supervision, and one study compared less intensive supervision with routine supervision. Most outcomes were scores relating to providers' practice, knowledge and provider or user satisfaction. The majority of the outcomes were measured within nine months after the interventions were introduced. In two studies comparing supervision with no supervision, small benefits on provider practice and knowledge were found. For methods of enhancing supervision, we identified five studies, and two studies of frequent supportive supervision demonstrated small benefits on workers performance. The one study examining the impact of less intensive supervision found no evidence that reducing the frequency of visits had any effect on the utilisation of services. The GRADE evidence quality for all comparisons and outcomes was "low" or "very low".

AUTHORS' CONCLUSIONS

It is uncertain whether supervision has a substantive, positive effect on the quality of primary health care in low- and middle-income countries. The long term effectiveness of supervision is unknown.

Treatment outcome of tuberculosis patients at Gondar University Teaching Hospital, Northwest Ethiopia. A five--year retrospective study

Background

In Gondar University Teaching Hospital standardized tuberculosis prevention and control programme, incorporating Directly Observed Treatment, Short Course (DOTS) started in 2000. According to the proposal of World Health Organization (WHO), treatment outcome is an important indicator of tuberculosis control programs. This study investigated the outcome of tuberculosis treatment at Gondar University Teaching Hospital in Northwest Ethiopia.

Methods

We analyzed the records of 4000 tuberculosis patients registered at Gondar University Teaching Hospital from September 2003 to May 2008. Treatment outcome and tuberculosis type were categorized according to the national tuberculosis control program guideline. Multivariate analysis using logistic regression model was used to analyse the association between treatment outcome and potential predictor variables.

Results

From the total of 4000 patients, tuberculosis type was categorized as extrapulmonary in 1133 (28.3%), smear negative pulmonary tuberculosis in 2196 (54.9%) and smear positive pulmonary tuberculosis in 671 (16.8%) cases. Of all patients, treatment outcome was classified as successfully treated in 1181(29.5%), defaulted in 730 (18.3%), died in 403 (10.1%), treatment failed in six (0.2%) and transferred out in 1680 (42.0%) patients. Males had the trend to be more likely to experience death or default than females, and the elderly were more likely to die than younger. The proportion of default rate was increased across the years from 97(9.2%) to 228(42.9%). Being female, age group 15-24 years, smear positive pulmonary tuberculosis and being urban resident were associated with higher treatment success rate.

Conclusion

The treatment success rate of tuberculosis patients was unsatisfactorily low (29.5%). A high proportion of patients died (10.1%) or defaulted (18.3%), which is a serious public health concern that needs to be addressed urgently.

Quality of tuberculosis care and its association with patient adherence to treatment in eight Ethiopian districts

BACKGROUND

Little is known about the quality of tuberculosis (TB) service delivery in public health facilities in Ethiopia and its association with patients' non-adherence to TB treatment. This study assessed the organization, management and processes of TB care delivery, and their effects on patients' adherence to TB treatment.

METHODS

The quality of TB care was investigated in 44 public health facilities from three perspectives: structure, processes of TB care delivery and patient treatment outcome. Quality of care was determined by adherence to national TB guidelines. On-site observations of TB service delivery and interviews with health providers were conducted to evaluate structural factors. Patients (n = 237) in the health facilities were interviewed prospectively at completion of their treatment to determine the quality of tuberculosis care delivered. Three measures of treatment adherence [treatment interruption (>or=2 weeks), availability of unused TB drugs and treatment default] were quantified from a review of patient treatment registers and an audit of unused TB drugs at patients' homes. Effects were identified of poor quality structures and processes of service delivery on these three measures of adherence.

RESULTS

TB care providers were untrained in 18 (44%) of 44 facilities and daily outpatient TB care was not given in 13 of 44 (25%). Among the 237 patients, 43% interrupted treatment for >or=15 days and 30% had at least 1 day's dose of TB drugs unused. Patients tended to interrupt and default from treatment when their care provider had been inadequately supervised by district TB control experts and was incapable of dealing with patients' minor illnesses. Unavailability of daily TB care in health facilities was associated with missing daily doses.

CONCLUSION

Better training of TB care providers and district supervisory support could be important interventions to improve the quality of care delivery and patient adherence to treatment.

Reminder systems and late patient tracers in the diagnosis and management of tuberculosis

BACKGROUND

Reminder systems and late patient tracers as strategies to improve patients' adherence to tuberculosis screening, diagnosis, and treatment are used in some countries, but their effectiveness has not previously been systematically reviewed.

OBJECTIVES

To assess the effects of reminder systems and late patient tracers on completion of diagnostics, commencement of treatment in people referred for curative or prophylactic treatment of tuberculosis, completion of treatment in people starting curative or prophylactic treatment for tuberculosis, and cure in people being treated for active tuberculosis.

SEARCH STRATEGY

We searched the Cochrane Infectious Diseases Group Specialized Register (June 2008), Cochrane Effective Practice and Organization of Care Group Specialized Register (April 2007), CENTRAL (The Cochrane Library 2008, Issue 2), MEDLINE (1966 to June 2008), EMBASE (1974 to June 2008), LILACS (1982 to June 2008), CINAHL (1982 to June 2008), SCI-EXPANDED (1945 to June 2008), SSCI (1956 to June 2008), mRCT (June 2008), Indian Journal of Tuberculosis (1983 to June 2008), and reference lists. We also contacted researchers working in the field.

SELECTION CRITERIA

Randomized controlled trials (RCTs), including cluster RCTs and quasi-RCTs, and controlled before-and-after studies comparing any reminders or late patient tracers with no or other kinds of reminders or late patient tracers. We included people in any setting who require treatment for tuberculosis or require prophylaxis against tuberculosis and are referred to tuberculosis diagnostic or screening services.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial risk of bias and extracted data. No meta-analysis could be undertaken due to the heterogeneity of interventions across trials.

MAIN RESULTS

Nine trials involving 5257 participants met the inclusion criteria. Three assessed the use of late patient tracers, and six assessed reminder systems. Late patient tracers (home visit and letter) were shown to be beneficial in increasing adherence to tuberculosis treatment compared with no late patient tracer. The results from almost all the reminder trials, except one, show benefits of different types of reminders compared to no reminder on adherence to tuberculosis clinic appointments.

AUTHORS' CONCLUSIONS

The included trials show significantly better outcomes among those tuberculosis patients for which late patient tracers and reminders are used. Studies of good quality (large and with rigorous study design) are needed to decide the most effective late patient tracer actions and reminders in different settings. Future studies of reminders in chemoprophylaxis and treatment settings would be useful.

Tuberculosis therapy and telemedicine

Directly observed therapy (DOT) ensures patient adherence through the administration of medications by trained health department personnel. This approach has been widely adopted in tuberculosis care. Unfortunately, DOT programs require a substantial commitment of scarce public health funds and personnel time. The application of telemedicine to DOT promises considerable cost and time savings.

The application of telemedicine technology to a directly observed therapy program for tuberculosis: a pilot project

We evaluated the use of videophone technology to provide directly observed therapy (DOT) to patients with active tuberculosis. During 304 treatment doses, adherence on videophone DOT was 95%, and patient acceptance of the technology was excellent. In selected cases, the use of videophone technology can maintain a high level of adherence to DOT in a cost-effective manner.

Antecedents of adherence to antituberculosis therapy

This correlational study identified antecedents of adherence to antituberculosis (anti-TB) therapy in a convenience sample of 62 English-speaking adults. From a demographic perspective, the study sample was similar to the referent population of TB patients in Georgia. A variety of parametric analyses revealed the following: The mean self-reported adherence score was 92.6% (SD = 3.3). Higher levels of self-reported adherence were associated with an annual income of $11,000 or more, education beyond high school, no current alcohol use, perceived support and absence of barriers to medication taking, strong intentions to adhere, and a high capacity for self-care. Those six variables accounted for 28% of adherence variance, F(6, 44) of 4.3, p = 0.0017. Additionally, belief in the usefulness and benefit of the medications was strongly correlated with intentions to adhere (r = 0.83, p < 0.001), and interpersonal aspects of care was significantly correlated with perceptions of medication utility (r = 0.65, p < 0.001), supports/barriers (r = 0.44, p < 0.001), intentions (r = 0.69, p < 0.001), and self-care (r = -0.42, p < 0.01). Persons who were diagnosed with both TB and human immunodeficiency virus (HIV) reported significantly lower adherence.

Interventions for promoting adherence to tuberculosis management

BACKGROUND

Up to half the people with tuberculosis do not complete their treatment. Strategies to improve adherence to treatment can be targeted at the person with the disease or at health workers.

OBJECTIVES

The objective of this review was to assess the effects of promoting adherence to anti-tuberculosis treatment and completion of diagnostic protocols for TB.

SEARCH STRATEGY

We searched the Cochrane Collaboration Trials, the Cochrane Effective Professional Practice Group trials register, the Cochrane Infectious Diseases Group trials register, Medline, Embase, Lilacs and reference lists of articles. We contacted experts in the field.

SELECTION CRITERIA

Randomised and quasi-randomised trials of interventions to promote adherence with curative or preventive chemotherapy and diagnostic protocols for tuberculosis.

DATA COLLECTION AND ANALYSIS

Two reviewers independently assessed trial quality and extracted data.

MAIN RESULTS

Eleven trials were included. Reminder cards sent to defaulters, a combination package of a monetary incentive and health education and more supervision of tuberculosis clinic staff increased the number of people completing their tuberculosis treatment. Direct observation by clinic nurses of people swallowing their tuberculosis drugs did not increase the likelihood of treatment success. Return to the clinic for reading of a tuberculin skin test was enhanced by monetary incentives, assistance by lay health workers, contracts and telephone prompts but not by health education.

REVIEWER'S CONCLUSIONS

We have found evidence of benefit for a number of specific interventions to improve adherence to anti-tuberculous therapy and completion of diagnostic protocols. These should be implemented by health care providers where appropriate to local circumstances. Future studies in low income countries are a priority and should measure adherence as well as clinical outcomes.

Changing doctor prescribing behaviour

The aim of this overview was to identify interventions that change doctor prescribing behaviour and to derive conclusions for practice and further research. Relevant studies (indicating prescribing as a behaviour change) were located from a database of studies maintained by the Cochrane Collaboration on Effective Professional Practice. This register is kept up to date by searching the following databases for reports of relevant research: DHSS-DATA; EMBASE; MEDLINE; SIGLE; Resource Database in Continuing Medical Education (1975-1994), along with bibliographies of related topics, hand searching of key journals and personal contact with content area experts. Randomised controlled trials and non-equivalent group designs with pre- and post-intervention measures were included. Outcome measures were those used by the study authors. For each study we determined whether these were positive, negative or inconclusive. Positive studies (+) were those that demonstrated a statistically significant change in the majority of outcomes measured at level of p < or = 0.05 between the intervention and control groups. Negative studies (-) showed a significant change in the opposite direction and inconclusive studies (approximately) showed no significant change compared to control or no overall positive findings. We identified 79 eligible studies which described 96 separate interventions to change prescribing behaviour. Of these interventions, 49 (51%, 41%-61%) showed a positive significant change compared to the control group but interpretation of specific interventions is limited due to wide and overlapping confidence intervals.

Effects of multidisciplinary case management in patients with chronic renal insufficiency

PURPOSE

Though case management has been recommended to improve the outcomes of patients with costly or morbid conditions, it has seldom been studied in controlled trials. We performed a randomized, controlled clinical trial of an intensive, multidisciplinary case management program for patients with chronic renal insufficiency and followed patients for 5 years.

PATIENTS AND METHODS

We enrolled 437 primary-care patients (73% of those eligible) with chronic renal insufficiency (estimated creatinine clearance consistently < 50 mL/min with the last serum creatinine level > 1.4 mg/dL) who were attending an urban academic general internal medicine practice. The intensive case management, administered during the first 2 years after enrollment, consisted of mandatory repeated consultations in a nephrology case management clinic staffed by two nephrologists, a renal nurse, a renal dietitian, and a social worker. Control patients received usual care. Primary outcome measurements included serum creatinine level, estimated creatinine clearance, health services use, and mortality in the 5 years after enrollment. Secondary measures included use of renal sparing and potentially nephrotoxic drugs.

RESULTS

There were no differences in renal function, health services use, or mortality in the first, second, or third through fifth years after enrollment. There were significantly more outpatient visits among intervention patients, mainly because of the added visits to the nephrology case management clinic. There were also no significant differences in the use of renal sparing or selected potentially nephrotoxic drugs. The annual direct costs of the intervention were $89,355 ($484 per intervention patient).

CONCLUSION

This intensive, multidisciplinary case-management intervention had no effect on the outcomes of care among primary-care patients with established chronic renal insufficiency. Such expensive and intrusive interventions, despite representing state-of-the-art care, should be tested prospectively before being widely introduced into practice.

Tuberculosis in the community: 2. The perceptions of members of a tuberculosis health team towards a voluntary health worker programme

SETTING

A voluntary community health worker programme, in the Western Cape, South Africa, utilizing volunteers to administer directly observed therapy to tuberculosis (TB) patients.

OBJECTIVE

This study describes the perceptions of health team members regarding the voluntary community health worker project.

DESIGN

A qualitative, participatory research study utilizing focus groups.

RESULTS

TB was perceived by the health team to be a stigmatized disease causing some patients to be reluctant to be associated with the TB control programme. Despite the project's dedicated approach to case-holding, volunteers expressed the need to develop skills in providing more comprehensive care. The volunteers appear to administer a more personalized service to TB patients and can bridge the gap between TB patients and the health agency.

CONCLUSION

Sustained evaluation and support seem to be a vital tool in integrating a volunteer project into a health team approach. Its effectiveness appears to depend to a large degree on the people involved.

Perception and social consequences of tuberculosis: a focus group study of tuberculosis patients in Sialkot, Pakistan

Treatment defaulting is one of the major causes of the failure of TB control programs. In Bethania Hospital, Sialkot, defaulting rates are high: 72% for the standard 12 months course and 56% for the 8 months course. Attrition is especially important in the first weeks of treatment: < 70% of the patients start the 10th week of treatment. A focus group discussion study has been carried out to gain a better understanding of the impact of social stigmatization, treatment cost and pregnancy on defaulting. The study population consisted of 3 male and 3 female groups each with 8 hospitalized TB patients. The study shows that TB is perceived as a very dangerous, infectious and incurable disease. This perception has many social consequences: stigmatization and social isolation of TB patients and their families: diminished marriage prospects for young TB patients, and even for their family members: TB in one of the partners may lead to divorce. Due to fear patients often deny the diagnosis and reject the treatment. While both male and female TB patients face many social and economical problems, female patients are more affected. Divorce and broken engagements seem to occur more often in female patients. Females are usually economically dependent on their husbands and family in law, and need their cooperation to avail of treatment. The belief that pregnancy enhances the risk for relapse decreases their marriage prospects. Pregnancy is also a reason for stopping TB treatment as both are considered as incompatible. The findings of this study reveal the urgent need for a health education campaign to convince the general population that tuberculosis is curable. All health care providers should act as destigmatizers.
