RESUMEN

AIMS: Irrational medicine use is a global crisis, but incidences are proportionately higher in low- and middle-income countries such as Sierra Leone. This study explores the structure, functions and challenges of drug and therapeutics committees (DTCs), an intervention towards irrational medicine use recently piloted in Sierra Leone. METHODS: A 2-phase mixed-method study design was used in this study. Firstly, a cross-sectional survey was conducted on all pharmacists who have worked for at least 1 year in DTC-piloted hospitals, using an online questionnaire to assess DTCs' structure, indicators and challenges. In phase 2, all eligible pharmacists were invited for a semistructured online interview using the WhatsApp messaging application to get deeper insights into the key issues that emerged from the survey; however, only 5 of the 7 consented to participate. MS Excel 2019 and NVivo version 12 were respectively used for data management and analysis. RESULTS: A total of 6 survey responses and 5 interviews were included in the analysis. Participants are pharmacists from the 7 hospitals in Sierra Leone where DTC was piloted. Most DTCs are comprised of a minimum of 10 members consisting of both medical and hospital administrative staff. The main functions of DTCs are ensuring rational medicines use, monitoring and reporting adverse drug reactions. All 7 hospitals with established pilot DTCs have different subcommittees operating at varying functionality levels, ranging from effective to nonfunctional. The main challenges in DTC functions and maintenance are funding (n = 6), DTC decision implementation (n = 4), and unmotivated members (n = 4). Strategies suggested to improve DTCs at public hospitals and nationwide include resource allocation, monitoring and evaluating DTC functions and its members' capacity building. CONCLUSION: DTCs present a compelling opportunity towards achieving rational medicines use at the hospital level in Sierra Leone. Nonetheless, the lack of funding and operational resources are significant limitations that must be noted by policymakers before expanding DTC programmes to other hospitals in Sierra Leone.

RESUMEN

The spread of drug-resistant tuberculosis (DR TB) poses significant challenges to the control and successful eradication of TB globally. The current retrospective study was designed to evaluate the treatment outcomes and identify the risk factors associated with unsuccessful outcomes among DR TB patients. A total of 277/308 eligible DR TB patients were enrolled for treatment at the programmatic management unit of DR TB at the Pakistan Institute of Medical Sciences, Islamabad between January 2014 and July 2019. Treatment outcomes were defined according to the WHO recommendations. Death, treatment failure, and lost to follow-up (LTFU) were collectively grouped as unsuccessful treatment outcomes, whereas cured and treatment completed were summed up together as successful treatment outcomes. Out of the total 277 patients, 265 (95.67%) were multidrug/rifampicin-resistant TB (MDR/RR-TB) cases, 8 (2.89%) were isoniazid resistant cases, and 4 (1.44%) were extensively drug-resistant ones. In the current cohort, a total of 177 (63.9%) achieved successful treatment outcomes. Among them, 153 (55.2%) were declared cured and 24 (8.7%) completed their treatment. Of the remaining 100 (36.1%) patients with unsuccessful outcomes, 60 (21.7%) died, 32 (11.5%) were LTFU, and 8 (2.9%) had failed treatment. The proportion of male patients was relatively higher (55.2%), within the age group of 21-40 years (47.3%) and lived in rural areas (66.8%). The multivariate analysis revealed that unsuccessful outcomes had a statistically significant association with being male (adjusted odds ratio, AOR: 1.92, 95% confidence interval (CI): 1.10-3.36), being in an age group above 60 years (AOR: 3.34, 95% CI: 1.09-10.1), suffering from any comorbidity (AOR: 2.69, 95% CI: 1.35-5.38), and the history of use of second-line drugs (AOR; 3.51, 95% CI 1.35-9.12). In conclusion, treatment outcomes among DR TB patients at the study site were poor and did not achieve the treatment success target (≥75%) set by the World Health Organization.

RESUMEN

Background: Antibiotic resistance (ABR) is one of the major issues around the globe. Timely education and awareness of pharmacy students regarding the appropriate use of antibiotics, ABR, and antimicrobial stewardships are required. Methods: The present study was first conducted in 12 (public and private sector) universities among undergraduate pharmacy students (UGPS) (n = 414) irrespective of their study year through a validated questionnaire, and the insights of pharmacy teachers were taken through in-depth semi-structured interviews in the second phase. For the quantitative data, different statistical methods were used, and data were presented in tabulated form, whereas inductive thematic interpretation was used to categorize themes and derive conclusions from qualitative evidence. Results: The majority of the students were males (n = 223, 54%) with the mean age group 19-23 years, and 20 faculty members were interviewed with a mean duration of 15 min. Students have good knowledge about antibiotics use and the majority purchased antibiotics through prescription (n = 277, 66.9%) during the last month and strongly agreed to stop unnecessary household storage (n = 183 44.2%). Most of the students have heard the terminologies related to antimicrobial resistance through social media while unaware (n = 104, 25.1%) of a Pakistan national action plan against AMR (antimicrobial resistance). Overall, respondents have a somewhat good understanding of the ABR. Regular use of antibiotics without consultation of a physician can lead to ABR and some wrong answers were observed (162, 39.1%; p > 0.05). The majority of the students (n = 198, 47.8%) and teachers believe that the current pharmacy syllabus must be swiftly updated with the new subjects related to ABR and AMS (antimicrobial stewardship) in Pakistan. The UGPS have emphasized (n = 220, 53.1%; Median = 1, IQR = 2) establishing a link between academia and hospitals. The ABR issue has been highlighted by pharmacy faculty members, who have urged students to take practical efforts toward ABR and AMS knowledge. Conclusion: The UGPS knowledge related to ABR and AMS must be updated. Students at the undergraduate level must get training in order to encourage the sensible use of antibiotics. Courses on ABR and AMS should be included in present pharmacy curricula.

RESUMEN

Human displacement is on the rise globally, and the increase in the burden of tuberculosis (TB) is also attributed to migrations worldwide. A significant number of such displacements occur in regions with considerably higher areas of TB burden. Displacements may delay TB diagnosis and treatment, which will possibly lead to TB transmission among healthy individuals. In this study, we assessed the association of existing determinants after a protracted internal displacement of people with delay in TB diagnosis and treatment outcomes. A cross-sectional study was conducted on internally displaced TB patients (IDPs), registered at selected health facilities in three urban districts of Pakistan from March 2019 to February 2020. The univariate and multivariate logistic regression model was used to assess the delay in diagnosis and treatment outcomes. IDPs with delay in initiation of treatment beyond 30 days were at high possibility of unsuccessful TB treatment outcomes (adjusted odds ratio AOR, 2.60; 95% CI 1.06-6.40). Furthermore, the multivariate regression analysis showed a statistically significant association (p > 0.05) between TB patients who were aged 55 to 65 years (AOR, 2.66; 95% CI 1.00-7.07), female patients (AOR, 2.42; 95% CI 1.21-4.81), visited non-formal health provider (AOR, 8.81; 95% CI 3.99-19.46), self-medication (AOR, 2.72; 95 % CI 1.37-5.37), poor knowledge of TB (AOR, 11.39; 95% CI 3.31-39.1), and perceived stigma (AOR, 8.81; 95% CI 3.99-19.4). Prolonged delay in treatment was associated with unfavorable treatment outcomes among IDPs. Migrants and IDPs are more likely to experience an interruption in care due to overall exclusion from social and health care services. Therefore, it is imperative to understand the barriers to providing public health care services, particularly in preventing and treating TB.

RESUMEN

INTRODUCTION: The excessive consumption of antibiotics is a significant contributor to antimicrobial resistance, especially in children. Children are often advised antibiotics for viral infections. In developing countries, drugstores are a prime source of easy access to nonprescription antibiotics. Moreover, in Pakistan, their irrational use is an "everyday routine". The study, therefore, aimed to evaluate the dispensing of nonprescription antibiotics to children. METHODS: Using pediatric acute diarrhea and acute upper respiratory infection as disease scenarios, a simulated client, cross-sectional study was conducted in Lahore, Pakistan, to explore the antibiotics' ease of availability at both categories of drugstores (pharmacies and medical stores) from November 1st, 2019 to January 31st, 2020. Chi-square (χ 2) test was used to compare the differences in practices of different categorical variables. Multivariable logistic regression was applied to analyze the association of various factors with antibiotics dispensing. RESULTS: Antibiotics were dispensed without prescription in 456 (59%) of 773 simulated visits out of which 425 (93.2%) were dispensed on the advice of the drugstore staff. A qualified pharmacist was available in only 164 (21.2%) cases. Of the 386 visits for acute diarrhea and 387 for acute upper respiratory infection, nonprescription antibiotic dispensing occurred in 259 (67.1%) and 197 (50.9%) visits, respectively. There were considerable differences (p-value <0.05) in the practices and antibiotics dispensing between each disease scenario presented. Moreover, antibiotics were less commonly dispensed at pharmacist-supervised drugstores compared to unsupervised ones. CONCLUSION: Overall, inappropriate dispensing practices were prevalent to a large extent at the drugstores, and antibiotics were effortlessly obtainable without prescription. The quality of the services provided, especially by the non-pharmacist staff, was also not satisfactory. Therefore, the Drug Regulating Authority of Pakistan must enforce strict implementation of drug laws at the drugstores without delay, especially in major cities to help curb the felonious use of antibiotics.

RESUMEN

Antibiotic resistance (ABR) is an emerging global threat to public health. Substantial evidence has indicated that community pharmacists (CPs) can play a critical role in managing the ever-increasing threat of antibiotic resistance. This study aimed to determine the knowledge, attitude, and practices of CPs (n = 180) towards antibiotics and antibiotic resistance as well as to improve the rational use of antibiotics. A two-phase mixed-methods (quantitative and qualitative) online study was conducted in Pakistan from August 2019 to March 2020 by using validated questionnaires and semi-structured interview data. Different statistical methods were used to tabulate the quantitative data, whereas inductive thematic analysis was conducted to categorize themes from the qualitative data and to draw conclusions. Approximately 64.4% of the CPs were male (mean: 29-33 years old). Overall, CPs had good knowledge of and were familiar with multidrug-resistant organisms and their roles in ABR (65.6%, median = 1, and IQR = 1), although their knowledge was poor in differentiating some antibiotic groups with their respective ABR patterns (31.1%, median = 1, and IQR = 1). Most CPs have a positive attitude towards antibiotics, with most (90.0%) identifying ABR as a critical issue in public health (median = 1 and IQR = 0). Overall, CPs' practices towards antibiotics were somewhat acceptable, where they leaned towards educating patients about the rational use of antibiotics (52.8%, median = 1, and IQR = 1). The two main themes discovered (antibiotics and counseling of patients) were related to self-medication, while educational intervention is the main subtheme. ABR is multifactorial, with subthemes related to budget, time constraints, incompetent staff, the absence of CPs, the lack of training, and the enforcement of laws and regulations being the needs of the hour in Pakistan. Effective antibiotic stewardship programs, patient education, and awareness campaigns about antibiotics and ABR along with training of the CPs are important factors that have to be addressed in a timely manner.

RESUMEN

Background Community pharmacists' role in the primary health care, patient-centered services, beyond traditional dispensing services is well established in the developed world. However, this role is not fully established in low-middle-income countries including Pakistan. Objective To explore community pharmacists' perspectives and preparedness about practice change and associated facilitators and barriers to extended services. Setting A study was conducted involving community pharmacists of Lahore, Pakistan. Method Two phased studies were conducted using mixed-method sequential design. The first phase involved qualitative semi-structured face-to-face interviews with the community pharmacists, while the second phase constituted a questionnaire-based cross-sectional study. Main outcome measure Pharmacists' perspectives about extended pharmacy services, facilitators, barriers and preparedness for the practice change. Results For the first phase, pharmacists were purposively sampled and the saturation yielded a final sample size of fifteen pharmacists (N = 15). The thematic content analysis yielded four distinct themes; (1) current practices and familiarity with extended pharmacy services (2) practice gap between Pakistan and the developed countries (3) facilitators and the preparedness, and (4) barriers towards its implementation and provision. The second part was a questionnaire-based cross-sectional phase, where a total of 348 community pharmacists were approached, while only 242 responded, yielding a response rate of 69.5%. The triangulation of qualitative and quantitative data identified several barriers such as; shortage of pharmacists, lack of knowledge and skills, poor collaboration with general practitioners, failure of customers to pay for extended services. Facilitators and preparedness for the provision of extended pharmacy services were; access to patient notes, follow-up, separate counselling areas, accreditation of specific services and sufficient resources. Conclusion This study's findings call for the implementation and enforcement of Punjab Drug Sale Rules 2007 to facilitate the practice change and provision of comprehensive pharmacy services in Punjab, Pakistan. There is a need for additional laws to define community pharmacists' roles, uniform job description, training, new funding model, separate area, and accreditation of extended pharmacy services in Pakistan.

RESUMEN

Antibiotic resistance (ABR) is a significant issue for public health globally. An adequate understanding of ABR and the approaches used to tackle ABR, including antibiotic stewardship programs, are vital. This study aimed to get an insight into antibiotic use, ABR, and antibiotic stewardship programs among pharmacy students of Punjab, Pakistan. This multicenter study was undertaken among final (fifth) year undergraduate pharmacy students of 7 universities of Punjab, Pakistan. A paper-based self-administered questionnaire comprising 48-items was utilized for data collection. Descriptive and inferential statistics were employed for data analysis. This study included a total of 296 respondents with a response rate of 85.8%. Most of the students had an average understanding of antibiotic use (59.8%), ABR (42.6%), ABR mechanisms (48.0%), and factors of ABR (51.7%). Only 21.6% of students have heard about antibiotic stewardship programs. More than half of the students believed that educating and training healthcare professionals (53.4%) and medical students (57.8%) about the prescribing and judicial usage of antibiotics could reduce the ABR burden. The awareness of most of the pharmacy students about certain aspects of antibiotic use, ABR, and stewardship programs was suboptimal.

RESUMEN

In the current outbreak of novel coronavirus (COVID-19), healthcare professionals (HCPs) have a primary role in combating the epidemic threat. HCPs are at high risk of not only contracting the infection but also spreading it unknowingly. It is of utmost importance to evaluate their knowledge, attitudes, and practices (KAP) and the ability to assess the risks associated with the outbreak. A cross-sectional online survey involving physicians, pharmacists, and nurses was conducted. A 39-itemed questionnaire based on the World Health Organization (WHO)COVID-19 risk assessment tool was shared with healthcare professionals in three purposively selected key divisions of Punjab province. Out of 500 healthcare professionals, 385 responded to the survey. The majority (70%) were aged 22-29 years; 144 (37.4%) physicians, 113 (29.4%) nurses, and 128 (33.2%) pharmacists completed the survey. Overall, 94.8% of healthcare professionals scored adequately (>14) for COVID-19-related knowledge; 97.9% displayed an optimistic attitude (>42) and 94.5% had an adequate practice score (>28). Kruskal-Wallis and Jonckheere-Terpstra tests showed significant differences (p < 0.05) in KAP and risk assessment scores among groups; physicians and nurses scored higher as compared to pharmacists. Further research and follow-up investigations on disaster management and risk assessment can help policy-makers better tackle future epidemics.

RESUMEN

The aim of this work was to develop, optimize and characterize a silymarin-laden polyvinylpyrrolidone (PVP)-polyethylene glycol (PEG) polymeric composite to resolve low aqueous solubility and dissolution rate problem of the drug. A number of silymarin-laden polymeric formulations were fabricated with different quantities of PVP K-30 and PEG 6000 by the solvent-evaporation method. The effect of PVP K-30 and PEG 6000 on the aqueous solubility and dissolution rate was investigated. The optimized formulation and its constituents were characterized using powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques. Both the PEG 6000 and PVP K-30 positively affected the aqueous solubility and dissolution rate of the drug. In particular, a formulation consisting of silymarin, PVP K-30 and PEG 6000 (0.25/1.5/1.5, w/w/w) furnished the highest solubility (24.39±2.95 mg/mL) and an excellent dissolution profile (~100% in 40 min). The solubility enhancement with this formulation was ~1150-fold as compared to plain silymarin powder. Moreover, all the constituents existed in the amorphous state in this silymarin-laden PVP-PEG polymeric composite. Accordingly, this formulation might be a promising tool to administer silymarin with an enhanced effect via the oral route.

RESUMEN

Abstract The aim of the present research was to develop a silymarin-laden PVP-nanocontainer providing ameliorated aqueous solubility and dissolution of the drug. Several silymarin-laden formulations were formed with varying quantities of PVP and SDS via the solvent evaporation method using the electrospraying technique. The influence of the hydrophilic carriers on solubility and dissolution was explored. The solid-state characterization was carried out by particle-size analysis, PXRD, DSC, FTIR and SEM. All of the formulations demonstrated better solubility and dissolution than did silymarin plain powder. Both the SDS and PVP had positive effects on solubility and dissolution of silymarin in the aqueous media. An increased solubility was attained as the drug/PVP ratio was 1/4; however, further increase in PVP did not provide significant improvement. In particular, a nanocontainer formulation prepared with silymarin, PVP and SDS (1/4/0.5, w/w/w) exhibited the best solubility (26432.76 ± 1749.00 μg/mL) and an excellent dissolution (~92 % in 20 min) than did silymarin plain powder. Also, it demonstrated similar dissolution profiles compared to a commercial product; therefore, might be bioequivalent to the commercial product (f 1 = 3 and f 2 = 69). Moreover, cumulative undersize distribution values as represented by X10, X50 and X90 were 201 ± 21.01 nm, 488 ± 36.05 nm and 392 ± 48.10 nm, respectively. The drug existed in the amorphous state in the PVP-nanocontainers with no strong chemical bonding with other excipients. Thus, this formulation might be used for more effective administration of silymarin via the oral route.
