Rights and Responsibilities of Tuberculosis Patients, and the Global Fund: A Qualitative Study

Patient adherence to tuberculosis treatment in the Indian subcontinent: systematic review and meta-synthesis of qualitative research

OBJECTIVES

How well patients adhere to their tuberculosis (TB) treatment influences their recovery and development of drug resistance, but influences on adherence are multiple and often competing. We synthesised qualitative studies from our setting in the Indian subcontinent to understand the dimensions and dynamics involved to help inform service provision.

DESIGN

Qualitative synthesis comprising inductive coding, thematic analysis and forming a conceptual framework.

DATA SOURCES

Medline (OVID), Embase (OVID), CINAHL (EBSCOHost), PsycINFO (EBSCOHost), Web of Science Core Collection, Cochrane Library and Epistemonikos were databases searched on 26 March 2020 for studies published since 1 January 2000.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included reports in English from the Indian subcontinent that used qualitative or mixed-methodology designs and reported findings around adherence to TB treatment. Full texts meeting eligibility were sampled based on 'thickness' (the richness of the qualitative data reported).

DATA EXTRACTION AND SYNTHESIS

Two reviewers used standardised methods to screen abstracts and code. Included studies were assessed for reliability and quality using a standard tool. Qualitative synthesis was performed by inductive coding, thematic analysis and developing conceptual framework.

RESULTS

Of 1729 abstracts screened from initial search, 59 were shortlisted for full-text review. Twenty-four studies that qualified as 'thick' were included in the synthesis. Studies were set in India (12), Pakistan (6), Nepal (3), Bangladesh (1) or in two or more of these countries (2). Of the 24 studies, all but one included people who were taking TB treatment (1 study included only healthcare providers), and 17 included healthcare workers, community members or both.We identified three themes: (1) personal influences on the people with TB include interconnections between their social role in the family unit, their own priorities in day-to-day living and their experience to date with the disease; (2) adherence is profoundly influenced by how individual healthcare providers interact with patients on treatment and address their needs; (3) adherence is influenced across communities by structural, social, economic and cultural factors related to treatment.

CONCLUSION

Staff in TB programmes require an understanding of the various competing influences on individuals undergoing treatment. Programmes need to have more flexible and people-centred approaches to service provision in order to achieve adherence, and thus improve treatment outcomes.

Perceptions of healthcare professionals and patients on the role of the pharmacist in TB management in Pakistan: A qualitative study

Background: Globally, tuberculosis (TB) is the second major cause of death from infectious diseases, particularly in developing countries. A multidisciplinary approach to the management of TB may help to curb the disease burden. Objective: The objective of this study was to outline the perceptions of healthcare professionals and patients regarding the potential role of pharmacists in TB management in Pakistan. Method: This was a large-scale qualitative study conducted at the Chest Disease Unit (CDU) of the Bahawal Victoria Hospital (BVH), Punjab, Pakistan. Data were collected through semi-structured interviews with physicians, pharmacists, and patients recruited using a mix of convenient and snowball sampling. The sample size was decided through standard saturation point criteria. All interviews were audio recorded and transcribed verbatim. The data were analyzed to draw conclusions using a thematic analysis approach. Results: Analysis of the data yielded 19 categories and seven themes. Physicians considered pharmacists qualified healthcare professionals, whereas patients considered them merely dispensers. Inventory management and dispensing of medicines were considered as major responsibilities of pharmacists. Physicians were extremely overburdened and wanted to delegate certain duties to pharmacists, subject to their prior extensive trainings. However, most of the physicians were unaware of the legal scope of pharmacy practice in Pakistan. With regard to the potential duties of pharmacists, physicians, pharmacists, and patients (patients-upon explaining the potential roles during the interview) endorsed monitoring, counseling, medicine brand selection, dose adjustment, inventory management, dispensing, and polypharmacy assessment as their potential roles. In view of all stakeholders, the rationale for integrating pharmacists in TB management included overburdened physicians, sub-standard patient care, medication safety issues, and patient dissatisfaction. The healthcare professionals highlighted that the major barriers to integrating pharmacists within the TB management system were limited interest of regulatory authorities and policy makers, followed by inadequate training and experience-driven questionable competency of pharmacists. Conclusion: The study participants acknowledged the potential role of pharmacists in TB management. However, it was emphasized that healthcare policy makers should devise strategies to overcome the underlying barriers before assigning medicine-related clinical roles to pharmacists.

Frequency and Management of Adverse Drug Reactions Among Drug-Resistant Tuberculosis Patients: Analysis From a Prospective Study

Drug-resistant tuberculosis (DR-TB) management is often linked with a higher rate of adverse drug reactions (ADRs) needing effective and timely management of these ADRs, which, if left untreated, may result in a higher rate of loss to follow-up of drug-resistant patients.

Study objective: The study was aimed at prospectively identifying the nature, frequency, suspected drugs, and management approaches for ADRs along with risk factors of ADRs occurrence among DR-TB patients at Nishtar Medical University, Hospital, Multan, Pakistan.

Materials and Methods: The prospective study included all the DR-TB patients enrolled for treatment from January 2016 to May 2017 at the study site. Patients were evaluated for the treatment-induced ADRs as per standard criteria of the National Tuberculosis Program, Pakistan. Multivariate logistic regression was used to assess the independent variables associated with the occurrence of ADRs.

Results: Out of 271 DR-TB patients included in the final analysis, it was observed that 55 patients (20.3%) experienced at least three ADRs. A total of 50 (18.5%) patients experienced zero adverse effects, while 15 (5.5%), 33 (12.2%), and 53 (19.6%) patients experienced one, two, and four ADRs, respectively. Gastrointestinal disturbances (66.7%), nervous system disorders (59.4%), and electrolyte disturbances (55.7%) remained the highest reported ADRs during therapy, followed by arthralgia (49.1%), ototoxicity (24%), pruritic reactions/rash (12.9%), dyspnoea (12.5%), and tinnitus (8.8%). Pulmonary cavitation at the baseline visit (p-value 0.001, OR 3.419; 95% CI (1.694–6.902) was significantly associated with the occurrence of ADRs among DR-TB patients.

Conclusion: The frequency of ADRs was high among the study cohort; however, these were managed effectively. Patients with recognized risk factors for ADRs occurrence need continuous clinical management efforts.

Frequency and Factors Associated With Adverse Events Among Multi-Drug Resistant Tuberculosis Patients in Pakistan: A Retrospective Study

Background

Treatment of multi-drug resistant tuberculosis (MDR-TB) for a prolonged period with comparatively less effective and more toxic second-line anti-TB drugs is associated with greater incidence of adverse events.

Study aim

This study aimed to evaluate the frequency and factors associated with occurrence of adverse events among patients with MDR-TB attending the Bahawal Victoria Hospital, Bahawalpur, Pakistan.

Study design

This retrospective study included all patients with MDR-TB who were registered and treated at the study site between June 2014 and December 2016 and had their treatment outcomes available at the time of data collection (i.e., November 2018).

Measures and outcomes

The Electronic Nominal Record System (ERNS) records, medical charts of patients, and laboratory reports were reviewed to obtain the data. Adverse events were reported as per the standard criteria recommended by the WHO. Multivariate binary logistic regression was used to find the independent factors associated with the occurrence of adverse events.

Results

A total of 179 patients with MDR-TB were included in the final analysis. Out of these, 114 (63.7%) patients experienced at least one adverse event during the course of their treatment. Depression was the most common adverse events (33%), followed by nausea and vomiting (27.4%) and arthralgia (27.4%). The factors associated with the occurrence of adverse events included presence of comorbidity (adjusted odds ratio [AOR] 2.951; 95% CI 1.423, 6.118) and being employed (AOR 3.445; 95% CI 1.188, 9.993).

Conclusion

Adverse events were prevalent in this cohort, however, resolved with the effective management approaches. Patients with identified factors for occurrence of adverse events need special attention and enhanced clinical management.

Treatment outcomes among multidrug-resistant TB patients in Bahawal Victoria Hospital, Bahawalpur, Pakistan: a retrospective record review

BACKGROUND

This study aims to evaluate the treatment outcomes and factors associated with unsuccessful treatment outcomes among multidrug-resistant TB (MDR-TB) patients.

METHOD

This was a retrospective observational study conducted at the Bahawal Victoria Hospital, Bahawalpur, Pakistan. The sociodemographic, clinical and treatment-related data of MDR-TB patients registered at the study site between June 2014 and December 2016 were retrospectively collected. Patients' treatment outcomes were categorized on the basis of WHO-recommended criteria. Multivariate binary logistic regression analysis was used to find the independent factors associated with unsuccessful treatment outcomes.

RESULTS

Out of 179 MDR-TB patients, 106 (59.2%) completed their treatment successfully. The remaining 73 patients (40.8%) had unsuccessful treatment outcomes, among whom 45 (25.1%) died, while 18 (10.1%) were lost to follow-up. Factors associated with unsuccessful treatment outcomes included age ≥40 y (AOR 4.310; p = 0.006), unsuccessful interim treatment outcomes (AOR 5.810; p = 0.032), occurrence of adverse events (AOR 0.290; p = 0.029) and ofloxacin resistance (AOR 2.952; p = 0.042).

CONCLUSION

The treatment success rate among the selected cohort of MDR-TB patients was less than the target of ≥75% set by the WHO in the End TB Strategy. The lower treatment success rate at the study site requires urgent attention from clinicians and program managers.

Molecular Epidemiological Information System to Support Management of Multidrug-Resistant Tuberculosis in Thailand: Abstract

OBJECTIVE

To support the End TB strategy with an informatics system that integrates genomic data and the geographic information system (GIS) of Mycobacterium tuberculosis (MTB) clinical isolates. We aim to develop a system prototype for implementing genomic data to support multiple drug-resistant tuberculosis (MDR-TB) control.

METHODS

A 12-step data value chain was applied to describe the information flow within the system. A prototyping-oriented system development method was utilized to test the feasibility of certain technical aspects of a system, and as specification tools to determine user requirements. A simulated dataset was entered as input for initial system testing.

RESULTS

System prototype, namely Integrated MOL Outbreak detection and Joint investigation (iMoji), was established. The data entry modules consisted of (1) patient registration, (2) sample registration, (3) laboratory data entry and data analysis, and (4) verification and approval of the analyzed data. The initial system test demonstrated connectivity among modules without error. The system was able to report integrated genomic data and GIS information of MDR-TB for clustering analysis.

CONCLUSION

iMoji provides an interactive model for determining molecular epidemiological links of MDR-TB and corresponding spatial information to guide public health interventions for tuberculosis control.

Treatment outcomes of extrapulmonary tuberculosis in Bahawalpur, Pakistan; a record review

Background

There is limited published data form Pakistan on treatment success rate among extrapulmonary tuberculosis (EPTB) patients. The aim of this study was to assess clinical form, treatment outcomes, and identify the factors associated with unfavorable treatment outcome among EPTB patients.

Methods

A retrospective study was conducted at the Chest Disease Unit of the Bahawal Victoria Hospital, Pakistan. Medical records of EPTB patients, registered at the study site from January 1, 2015 to September 30, 2017, were reviewed to obtain the data. Final treatment outcomes among EPTB patients were evaluated in accordance with the standard Word Health Organization (WHO) criteria. Multivariate binary logistic regression analysis was used to identify the factors associated with unfavorable treatment outcome.

Results

A total of 651 EPTB patients were included in the study. Highest proportion of patients had pleural TB (n = 217, 33.3%). Out of the total 651 patients, 463 (71.1%) successfully completed the treatment. Among 177 (27.2%) patients with unfavorable treatment outcome, 10 (1.5%) died, while 165 (25.4%) lost to follow-up the treatment. Lymph node TB (AOR 0.65, 95% CI 0.422, 0.989) and meningeal TB (AOR 2.1, 95% CI 1.065, 4.144) were significantly associated with unfavorable treatment outcome.

Conclusion

The treatment success (favorable outcome) rate among EPTB patients was less than the target (i.e., ≥ 90%) set by the WHO. Highest proportion of patients lost to follow-up during the treatment.

A qualitative study to explore the role of pharmacists in healthy weight management in adults in Pakistan: current scenario and future perspectives

Background

Pharmacists possess significant potential for providing health services to the public when it comes to issues of weight management. However, this practice has not been observed in most parts of the world including low- and middle-income countries (LMICs) such as Pakistan. The aim of this study was to explore the potential role of pharmacists in providing healthy weight management (HWM) services to adults in Pakistan, and the barriers associated with the implementation of this type of role.

Methods

This descriptive qualitative study was set in seven hospitals (public and private) and three chain pharmacies in Lahore, Punjab – a province of Pakistan. Data was collected from in-depth individual interviews with pharmacists (n = 19) and medical doctors (n = 15). Purposive sampling techniques were applied to recruit both types of study participants. Telephone contact was made by the trained data collectors with the pharmacists to set the date and time of the interview after explaining to them the purpose of the study and obtaining their willingness and verbal recorded consent to participate. Registered medical doctors were recruited through snowball sampling techniques. The sample size was determined by applying the point at which thematic saturation occurred. All interviews were audio-recorded and transcribed verbatim. The data were analyzed to draw conclusions using inductive thematic content analysis.

Results

Through inductive qualitative analysis eight themes emerged; potential role for community pharmacists, collaborative approaches, barriers, ideal pharmacist-based weight management program, professional requirements and need for training, potential for implementation, current scenario in pharmacies and level of trust of pharmacists. The first six themes were common to both pharmacists and medical professionals. The unique theme for doctors was the ‘level of trust of pharmacists’, and for the pharmacists was the ‘current scenario in pharmacies’.

Conclusion

The majority of participants in our study had strong convictions that Pakistani pharmacists have the potential for provide effective HWM services to their communities. Of concern, none of the participating pharmacies were offering any sort of weight management program and none of the medical professionals interviewed were aware of HWM programs taking place. Medical doctors were of the opinion that pharmacists alone cannot run these programs. Doctor participants were firm that after being adequately trained, pharmacists should only carry out non-pharmacological interventions. To implement a HWM pharmacy model in Pakistan, it is necessary to overcome barriers outlined in this study.

What quality of care means to tuberculosis survivors

Quality of care for patients of TB suffers in India as well as in other countries, because the commonly accepted definitions of high quality care, rarely goes beyond correct diagnosis, treatment and adherence. The problem with the existing definitions and metrics of quality careis that they leave out patients, and when high quality care is defined without patients' perspectives, their needs and expectations are not addressed. Thispaper, based on a workshop held by TB survivors, attempts to examine the current state of quality of care extended to patients of TB, and to improve the scope of this care for the affected individuals, by the government, the healthcare system, and the society. The aim of the workshop and this paperis to arrive at a comprehensive, inclusive, and most importantly, a patient-centric definition of what quality of care looks like - to them.

Improving the design of studies evaluating the impact of diagnostic tests for tuberculosis on health outcomes: a qualitative study of perspectives of diverse stakeholders

Background: Studies evaluating the impact of Xpert MTB/RIF testing for tuberculosis (TB) have demonstrated varied effects on health outcomes with many studies showing inconclusive results. We explored perceptions among diverse stakeholders about studies evaluating the impact of TB diagnostic tests, and identified suggestions for improving these studies. Methods: We used purposive sampling with consideration for differing expertise and geographical balance and conducted in depth semi-structured interviews. We interviewed English-speaking participants, including TB patients, and others involved in research, care or decision-making about TB diagnostics. We used the thematic approach to code and analyse the interview transcripts. Results: We interviewed 31 participants. Our study showed that stakeholders had different expectations with regard to test impact and how it is measured. TB test impact studies were perceived to be important for supporting implementation of tests but there were concerns about the unrealistic expectations placed on tests to improve outcomes in health systems with many influencing factors. To improve TB test impact studies, respondents suggested conducting health system assessments prior to the study; developing clear guidance on the study methodology and interpretation; improving study design by describing questions and interventions that consider the influences of the health-care ecosystem on the diagnostic test; selecting the target population at the health-care level most likely to benefit from the test; setting realistic targets for effect sizes in the sample size calculations; and interpreting study results carefully and avoiding categorisation and interpretation of results based on statistical significance alone. Researchers should involve multiple stakeholders in the design of studies. Advocating for more funding to support robust studies is essential. Conclusion: TB test impact studies were perceived to be important to support implementation of tests but there were concerns about their complexity. Process evaluations of their health system context and guidance for their design and interpretation are recommended.

What drives inappropriate use of antibiotics? A mixed methods study from Bahawalpur, Pakistan

Purpose

This study investigates the knowledge, attitudes and practices of the general public regarding the use of antibiotics in community pharmacy, in Pakistan.

Methods

This is a mixed method study where data were collected through a validated questionnaire and semi-structured interviews. Convenience sampling techniques were used to recruit participants from the general public of Bahawalpur, Pakistan who visited pharmacies to purchase antibiotics between 1 June 2018 and 31 July 2018. Descriptive statistics and regression analyses were used to tabulate the results of quantitative data while inductive thematic analysis was used to identify themes and draw conclusions from the qualitative data.

Results

Over 60% of the 400 survey participants (n=246; 61.5%) had a moderate level of antibiotic knowledge; however, attitudes regarding antibiotics use were poor in half the sample (n=201; 50.3%). More than half (n=226; 56.6%) of the respondents stated that antibiotics could cure all types of infections. Just under one third (n=129; 32.3%) of respondents obtained the appropriate dosage regimen while the majority did not complete the course (n=369; 92.3%); stopping when they felt better. Inductive thematic analysis yielded four themes, 10 subthemes and 27 categories. Two subthemes were related to knowledge, one to attitude, three to practices and four subthemes were related to suggestions to improve the healthcare system. Inappropriate antibiotic practices included: lack of consultation with healthcare professionals, purchase of antibiotics without prescription or refilling of previous prescription, use of home supply of antibiotics, sharing of antibiotics with others, improper dosage regimens and early cessation of antibiotic therapy.

Conclusion

Level of education, low health literacy, high consultation fees of private practitioners, inadequate health facilities in government hospitals and patient overload, busy schedules of people, poor healthcare infrastructure in rural areas and unrestricted supply of antibiotics were key factors associated with inappropriate use of antibiotics in Pakistan.

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.

Factors affecting patients' knowledge about dispensed medicines: A Qualitative study of healthcare professionals and patients in Pakistan

BACKGROUND

Patients' knowledge about their prescribed medicines is one of the most important antecedents of successful therapy. Poor knowledge about medicines can lead to serious consequences such as non-adherence and misunderstanding of the significance of adverse events. The objective of this study is to understand the factors that are responsible for a patients' lack of knowledge regarding their medicines, by taking the perspective of the patient as well as that of healthcare professionals. Much of the work in this area has been undertaken in the setting of developed or semi-developed countries, and there is a scarcity of information from developing nations such as Pakistan.

METHODS

This was a large qualitative study set in the hospital outpatient environment in a teaching hospital in the Punjab province of Pakistan. Data were collected from dialogue with patients (n = 19) and healthcare providers (n = 16) i.e., doctors and dispensers (where a dispenser is a person who merely dispenses medicines; i.e. is not a pharmacist) through in-depth semi-structured interviews. Patients having limited knowledge about their dispensed medicines were assessed using a checklist. The healthcare providers were recruited through a convenience sampling strategy, based on their availability and willingness to participate in the study. Based on the objectives of the study, a pilot tested interview protocol was developed, and used to conduct the interviews. The sample size was controlled by using saturation point criteria. All interviews were audio recorded and transcribed verbatim. The data were analyzed to draw conclusions using inductive thematic content analysis.

RESULTS

The analysis of data yielded 31 categories (patients = 19, healthcare professionals = 12), 10 subthemes and three themes. The major themes were healthcare professional-related factors, patient-related factors and system-related factors. The health professional related subthemes included: behaviour and attitude and professional liabilities and liaison. The patient related subthemes included: eagerness of the patients and lack of understanding and misconception. The system-related factors included: patients with special needs, perceived role of the pharmacist, prescription and medicines, and staff workload.

CONCLUSION

Healthcare professional related, patient related and system related factors have a significant influence on patients' knowledge about dispensed medicines. The non-professional behaviour of doctors, increased staff workload, inadequate time and attention provided by healthcare professionals to patients, illiteracy of patients, lack of specialized labelling on medicines for illiterate patients and absence of pharmacists at the hospital, were the major concerns identified in this study. The study points to a need for appropriate patient education and counselling with regards medicines, improved coordination between hospital staff, and provision of some basic system-related facilities which are pivotal for enhancing patients' knowledge and adherence to their treatment regimens.

Identification of risk factors for enteral feeding intolerance screening in critically ill patients

Objectives:

To identify risk factors for enteral feeding intolerance screening in critically ill patients, thereby, provide some reference for healthcare staff to assess the risk of feeding intolerance, and lay the foundation for future scale development.

Methods:

This study used a mixed methodology, including a literature review, semi-structured interviews, the Delphi technique, and the analytic hierarchy process. We used the literature review and semi-structured interviews (n=22) to draft a preliminarily item pool for feeding intolerance, Delphi technique (n=30) to screen and determine the items, and the analytic hierarchy process to calculate the weight of each item. The study was conducted between June 2014 and September 2015 in Daping Hospital, Third Military Medical University, Chongqing, China.

Results:

Twenty-three risk factors were selected for the scale, including 5 dimensions. We assigned a weight to each item according to their impact on the feeding intolerance, with a higher score indicating a greater impact. The weight of each dimension was decreasing as follows: patient conditions, weight score equals 42; general conditions, weight score equals 23; gastrointestinal functions, weight score equals 15; biochemical indexes, weight score equals 14; and treatment measures, weight score equals 6.

Conclusion:

Developed list of risk factors based on literature review, survey among health care professionals and expert consensus should provide a basis for future studies assessing the risk of feeding intolerance in critically ill patients.

A rating instrument for fear of hospitalisation

AIMS AND OBJECTIVES

To develop and validate a reliable instrument that can measure fear of hospitalisation experienced by outpatients.

BACKGROUND

After having a diagnosis established, some patients experience sense of fear, unpleasantness and embarrassment due to the possibility to be admitted to a hospital. Currently, there is no available instrument for measuring fear of hospitalisation.

DESIGN

Cross-sectional study for assessing reliability and validity of a questionnaire.

METHOD

The questionnaire with 17 items and answers according to the Likert scale was developed during two brainstorming sessions of the research team. Its reliability, validity and temporal stability were tested on the sample of 330 outpatients. The study was multicentric, involving patients from seven cities and three countries.

RESULTS

Fear of hospitalisation scale showed satisfactory reliability, when rated both by the investigators (Cronbach's alpha .799) and by the patients themselves (Cronbach's alpha .760). It is temporally stable, and both divergent and convergent validity tests had good results. Factorial analysis revealed three domains: fear of being injured, trust to medical staff and fear of losing privacy or autonomy.

CONCLUSIONS

This study developed new reliable and valid instrument for measuring fear of hospitalisation.

RELEVANCE TO CLINICAL PRACTICE

Identification of patients with high level of fear of hospitalisation by this instrument should help clinicians to administer measures which may decrease fear and prevent avoidance of healthcare utilisation.

Predictors of unsuccessful interim treatment outcomes of multidrug resistant tuberculosis patients

Background

Interim treatment outcomes at 6-months for multidrug-resistant tuberculosis (MDR-TB) treatment are among the most basic performance monitoring and key evaluation indicators in the Stop and End TB strategy of the World Health Organization (WHO). Therefore, this study was conducted to evaluate the interim treatment outcomes of MDR-TB patients in Pakistan.

Methods

This study was conducted at the Programmatic Management Unit for Drug-resistance TB (PMDT) site of the National Tuberculosis Program (NTP), Pakistan. It is located in the Chest Disease Unit (CDU) of the Bahawal Victoria Hospital (BVH), Bahawalpur, Punjab, Pakistan. Data was collected between April 1, 2014 and December 31, 2015. The medical records, Electronic Nominal Recording Reporting System (ENRS) data and MRD-TB notification forms of the MDR-TB patients registered at the PMDT site were reviewed to obtain data. For reporting and calculation of interim treatment outcomes, standardized WHO methodology was adopted. Simple logistic regression analysis was used to examine the possible association between the dependent variable (i.e. unsuccessful interim treatment outcome) and selected socio-demographic and clinical variables.

Results

A total of 100 drug-resistant TB (DR-TB) patients (all types) were registered during the study period. Out of these, 80 were MDR-TB patients for whom interim results were available. Out of the 80 MDR-TB cases, 48 (60%) were classified under the successful interim treatment outcome category. The remaining 40% had unsuccessful 6-month treatment outcomes and 12 (15%) patients died, while nine (11.3%) were lost to follow-up by six months. The final predictors of unsuccessful interim treatment outcomes were; being resistant to ofloxacin (AOR 3.23, 95% CI 0.96–10.89; p-value = 0.04), having above normal baseline serum creatinine levels (AOR 6.49, 95% CI 1.39–30.27; p-value = 0.02), and being culture positive at the second month of treatment (AOR 6.94, 95% CI 2–24.12; p-value = 0.01).

Conclusions

Despite free treatment and programmatic efforts to ensure patient adherence, the high rate of unsuccessful interim treatment outcomes is concerning. The identified risk factors for unsuccessful interim treatment outcomes in the current study provides clinicians an opportunity to identify high-risk patients and ensure enhanced clinical management and greater treatment success rates.

Drug utilization patterns among elderly hospitalized patients on poly-pharmacy in Punjab, Pakistan

BACKGROUND

Reports from drug utilization reviews are important tools employed in the assessment of healthcare practices. The objective of this study was to evaluate drug utilization patterns among elderly hospitalized patients on poly-pharmacy regimens in Pakistan.

METHODS

A descriptive, non-experimental, cross-sectional study was carried out from December 2015 to March 2016 in six tertiary-care hospitals in the Punjab province of Pakistan. The population under study were patients aged ≥60 years, taking ≥5 medicines per day (i.e., patients on poly-pharmacy) and who were hospitalized in the selected tertiary-care hospitals. In this study, data was collected from 600 hospitalized elderly patients (100 patients per hospital). All medicines prescribed on each in-patient chart were noted on a pre-designed pro-forma sheet and were classified under the Anatomical Therapeutic Chemical (ATC) classification system. Multiple linear regression analysis was used to determine the independent factors associated with poly-pharmacy in this cohort. Statistical Package for Social Sciences (SPSS) was used to analyze the data. P-value < .05 indicated statistical significance.

RESULTS

In 600 hospitalized in-patient (male 52.7% and female 47.3%) medication charts, 3179 medicines were prescribed. The most commonly prescribed drug classes were: A: alimentary tract and metabolism 80% (A02: drugs for acid related disorders 64.5%, A03: drugs for functional gastrointestinal disorders 21.5%), N: nervous system 66.3% (N02: analgesics 67.2%, N03: antiepileptic's 11.2%), J: anti-infectives for systemic use 62.2% (J01: antibacterial for systemic use 82.5%, J04: antimycobacterials 15.3%) and C: cardiovascular system 48.3% (C07: beta blocking agents 19.8%, C10: lipid modifying agents 16.5%), respectively. The most commonly prescribed active substances were: A02BC01 (omeprazole 51.3%), N02BE01 (paracetamol 50.8%) and J01DD04 (ceftriaxone 40.2%), respectively. In multiple linear regression analysis, male gender (95% CI -.205, -.006, p = .039, B = -.091), being divorced (95% CI -.604, -.136, p = .002, B = -.130) and presence of comorbidity (95% CI .068, .267, p = .001, B = .144) were the independent factors associated with increased drug use among elderly hospitalized patients on poly-pharmacy.

CONCLUSIONS

The rational use of medicines is of utmost importance, most particularly in the elderly population. More consideration should be given to rationalizing pharmacotherapy in elderly hospitalized patients who are on poly-pharmacy regimens in Pakistan.
