Comprehensiveness of primary services in the care of infectious tuberculosis patients in Rawalpindi, Pakistan

How do private practitioners in Pakistan manage children suspected having tuberculosis? A cross sectional study

Background

In Pakistan, private providers provide a large portion of health care, including for tuberculosis (TB). All TB patients are supposed to be reported to the National Tuberculosis Program (NTP), which provides drugs free of charge in addition to monitoring, supervision, and support. However, diagnosis of TB in children is difficult. We aimed to assess the private health care providers’ investigation practices and management of childhood TB.

Methods

We used a cross-sectional study, which was based on a national survey measuring under-reporting of children with TB in 12 selected districts in Pakistan from April–June, 2016. We explored the practices of the private health care providers, including the health care workers i.e. general practitioners, pediatricians, pulmonologists and chest specialists, who were involved in the diagnosis of TB in children under 15 years for investigating and managing children suspected having TB.

Results

Among 6519 presumptive child TB cases, a total of 5193(79.7%) children under 15 years were diagnosed as TB by private health care providers during second quarter, 2016. Only 187(2.9%) were notified to NTP. The majority of presumptive child TB cases reported cough, fever, and failure to thrive; few had TB contacts with pulmonary TB patients. Failure to thrive, loss of body weight and absence of BCG (Bacillus Calmette–Guérin) scar was more common in female children. Private providers relied on chest X-ray in 46.1%, while tuberculin skin test and Gene-Xpert MTB/RIF testing was little utilized. Bacteriological confirmation was present in 7.6%, and clinical assessment was the only basis for diagnosis in 39.3%. Of children with presumptive TB, only 955(14.6%) children were treated by private provider, while 3121(47.9%) cases were referred for diagnosis and 2443(37.5%) were referred after diagnosis for treatment; among all the referred, 3812(68.5%) were sent for investigations to District TB Centre (NTP).

Conclusion

This study showed that many private providers referred children suspected having TB to laboratories for further diagnosis, but the cases identified in these investigations were often not notified to the NTP. This problem could be resolved by strengthening the referral linkages between private health providers, NTP laboratories and treatment centres through capacity building and training of their staff.

Building sustainable operational research capacity in Pakistan: starting with tuberculosis and expanding to other public health problems

Background: For many years, operational research capacity has been a challenge and has remained a low priority for the health sector in Pakistan. Building research capacity for developing a critical mass of researchers in Pakistan was done through Structured Operational Research and Training Initiative (SORT IT) courses in Paris and Asia between 2010 and 2016.

Objective: The aim of this paper is to describe the journey of SORT-IT in Pakistan from its inception to progressive expansion and discuss the challenges and ways forward.

Methods: The journey began with the training of the Pakistan NTP research team lead in 2010 in an international SORT IT course at Paris. This was followed by training of two team members in Asia SORT IT courses in 2014 and 2015. These three then worked together to conceive and implement the first national Pakistan SORT IT course supported by WHO/TDR and the Global Fund in 2016. This was facilitated by international facilitators and local trained SORT-IT participants from Paris and Asia. This was followed by two further national SORT IT courses in 2017 and 2018.

Results: Between 2010 and 2017, a total of 34 participants from Pakistan had been enrolled in national and international SORT IT courses. Of the 23 participants from completed courses, 18(78%) successfully completed the course. In total 18 papers were submitted and up until June 2018, 15(83%) have been published and 21 institutions in Pakistan involved with operational research as a result of the SORT IT initiative.

Conclusions: The SORT IT course has been an effective way to build operational research capacity at national level and this has resulted in a large number of published papers providing local evidence for decision making on TB and other disease control programmes. The experience from Pakistan should stimulate other countries to adopt the SORT-IT model.

Analysis of tuberculosis treatment outcomes among pulmonary tuberculosis patients in Bahawalpur, Pakistan

OBJECTIVE

Monitoring tuberculosis treatment outcomes and understanding the reasons for unsuccessful treatment are important indicators for evaluating the performance of the national tuberculosis control program. The aim of this study was to evaluate the treatment outcomes among pulmonary TB (PTB) patients and identify the predictors of unsuccessful treatment outcome.

RESULTS

Treatment success rate of 67.8% among new and retreatment PTB patients and 69% in new smear positive PTB patients was observed. Close to 21% (20.9%) and 15.7% PTB and new smear positive PTB patients had loss to follow-up during treatment. Overall, older patients (AOR 1.02; 95% CI 1.01-1.0), smokers (AOR 1.65; 95% CI 1.02-2.67) and retreatment cases of TB (AOR 2.34; 95% CI 1.43-3.84) were at greater risk of having unsuccessful treatment outcomes. Moreover, sputum positivity at 2 months (AOR 13.78; 95% CI 5.09-37.26) was a significant predictor of poor treatment outcomes in new smear positive PTB patients. The treatment success rate among PTB patients was lower than the recommended 85% success rate. TB patients at higher risk of unsuccessful treatment outcomes should be provided with enhanced supervision and treatment monitoring to improve the success rate of TB management in Pakistan.

Loss-to-follow-up and delay to treatment initiation in Pakistan's national tuberculosis control programme

BACKGROUND

Researchers and policy-makers have identified loss to follow-up as a major programmatic problem. Therefore, the objective of this study is to quantify TB related pre-treatment loss to follow up and treatment delay in private sector health care facilities in Pakistan.

METHODS

This was a retrospective, descriptive cohort study using routinely collected programmatic data from TB referral, diagnosis and treatment registers. Data from 48 private healthcare facilities were collected using an online questionnaire prepared in ODK Collect, for the period October 2015 to March 2016. Data were analysed using SPSS. We calculated the: (1) number and proportion of patients who were lost to follow-up during the diagnostic period, (2) number and proportion of patients with pre-treatment loss to follow-up, and (3) the number of days between diagnosis and initiation of treatment.

RESULTS

One thousand five hundred ninety-six persons with presumptive TB were referred to the laboratory. Of these, 96% (n = 1538) submitted an on-the-spot sputum sample. Of the 1538 people, 1462 (95%) people subsequently visited the laboratory to submit the early morning (i.e. the second) sample. Hence, loss to follow-up during the diagnostic process was 8% overall (n = 134). Of the 1462 people who submitted both sputum samples, 243 (17%) were diagnosed with sputum smear-positive pulmonary TB and 231 were registered for anti-TB treatment, hence, loss in the pre-treatment phase was 4.9% (n = 12). 152 persons with TB (66%) initiated TB treatment either on the day of TB diagnosis or the next day. A further 79 persons with TB (34%) commenced TB treatment within a mean time of 7 days (range 2 to 64 days).

CONCLUSION

Concentrated efforts should be made by the National TB Control Programme to retain TB patients and innovative methods such as text reminders and behavior change communication may need to be used and tested.

Alarming rates of attrition among tuberculosis patients in public-private facilities in Lahore, Pakistan

Setting: All public-private mix (PPM) facilities caring for tuberculosis (TB) patients in Lahore city, Pakistan, under four models: PPM1 (general practitioners), PPM2 (non-governmental organisations), PPM3 (private hospitals) and PPM4 (others). Objective: To assess the pre-treatment loss to follow-up (LTFU), defined as patients documented in the laboratory registers but not in the treatment registers of any PPM facility, among sputum smear-positive TB patients diagnosed during January-March 2015, and unfavourable treatment outcomes among patients registered for treatment and associated factors. Design: This was a retrospective cohort study reviewing existing programme records. Poisson regression was used to identify factors associated with outcomes. Results: Of 2473 patients diagnosed, 1590 (64%) were lost to follow-up before treatment. This was higher among males (68%) and the elderly (79%), and lower among 'high positives' (smear grading 2+ or 3+, 53%) and in the PPM1 model (34%). Of 883 patients started on treatment, 165 (19%) had unfavourable outcomes: 8% LTFU, 5% treatment failure, 3% died and 3% not evaluated. Previously treated patients (34%) and children (44%) had the worst outcomes. Conclusion: Pre-treatment LTFU was alarmingly high and requires urgent attention, including the development and institution of mechanisms for patient tracking using information and mobile phone technology, and making TB notification mandatory in the private sector.

Pre-treatment loss to follow-up among smear-positive TB patients in tertiary hospitals, Quetta, Pakistan

Setting: Three public sector tertiary care hospitals in Quetta, Balochistan, Pakistan, with anecdotal evidence of gaps between the diagnosis and treatment of patients with tuberculosis (TB). Objectives: To assess the proportion of pre-treatment loss to follow-up (LTFU), defined as no documented evidence of treatment initiation or referral in TB registers, among smear-positive pulmonary TB patients diagnosed in 2015, and the associated sociodemographic factors. Design: A retrospective cohort study involving the review of laboratory and TB registers. Results: Of 1110 smear-positive TB patients diagnosed (58% female, median age 40 years, 5% from outside the province or the country), 235 (21.2%) were lost to follow-up before starting treatment. Pre-treatment LTFU was higher among males; in patients residing far away, in rural areas, outside the province or the country; and in those without a mobile phone number. Conclusion: About one fifth of the smear-positive TB patients were lost to follow-up before starting treatment. Strengthening the referral and feedback mechanisms and using information technology to improve the tracing of patients is urgently required. Further qualitative research is needed to understand the reasons for pre-treatment LTFU from the patient's perspective.

Validation of sputum smear results in the Electronic TB Register for the management of tuberculosis, South Africa

BACKGROUND

The accuracy of tuberculosis (TB) surveillance systems is paramount in TB control. In South Africa, information from the laboratory is not directly linked to the Electronic TB Register (ETR).

OBJECTIVE

To validate smear results recorded in the ETR with those recorded in the laboratory.

METHODS

A retrospective evaluation was conducted among all sputum smear-positive TB patients recorded in the ETR during the fourth quarter of 2009 in KwaZulu-Natal Province.

RESULTS

Of 1036 smear-positive patients recorded in the ETR, 683 (65.9%) had positive results recorded in the laboratory register. Only 364 (53.2%) had their smear results recorded in the ETR at the end of the intensive phase of treatment; of 326 (89.6%) recorded as converted to smear-negative, 224 (61.5%) were confirmed as smear-negative in the laboratory. Of 331 patients with end-of-treatment results in the ETR, 302 (91.2%) were recorded as cured, but only 105 (34.8%) were confirmed in the laboratory.

CONCLUSIONS

Over a third of TB patients registered as smear-positive in the ETR could not be confirmed based on laboratory results. Many patients did not have a laboratory record, lending to uncertainty as to the validity of the smear results and treatment outcomes recorded in the ETR.
