Spectrum of Microorganisms, Antibiotic Resistance Pattern, and Treatment Outcomes Among Patients With Empyema Thoracis: A Descriptive Cross-Sectional Study From the Bahawal Victoria Hospital Bahawalpur, Punjab, Pakistan.

ABSTRACT: Background: This study involves the analysis of spectrum of microorganisms, antibiotic resistance pattern, and treatment outcomes among empyema thoracis patients. This study also analyzes the factors associated with unsuccessful treatment outcome and duration of hospital stay among the patients. Methods: This was a descriptive, cross-sectional study carried out in the Pulmonology Ward of the Bahawal Victoria hospital, Bahawalpur, Pakistan. All patients with empyema thoracis registered at the study site during the period of 1 year were included in the study. Multivariate regression analysis was used to analyze the factors associated with duration of hospital stay and unsuccessful treatment outcome among the patients. Results: A total 110 patients were included in the study. Most of the patients (n = 73, 66.4%) were treated with piperacillin/tazobactam alone and in combination with either one or more than one antibiotics as an empiric therapy. Culture was positive in 58 (52.7%) patients and the most commonly identified organisms included, gram-negative Pseudomonas aeruginosa (n = 20; 18.8%) and Klebsiella sp. (n = 11, 10%) followed by same proportion of E. coli. The most commonly identified bacterial isolates showed high level of resistance against antibiotics used as an empiric therapy, while these showed low level of resistance against amoxicillin, clarithromycin, ertapenem, colistin, tigecycline, fosfomycin, rifampicin, and vancomycin. In this study, 82 (74.5%) patients successfully completed the treatment, while 12 (11%) showed no clinical improvement, 5 (4.5%) lost to follow up and 11 (10%) died. In multivariate binary logistic regression analysis, none of the patient attributes were significantly associated with unsuccessful treatment outcome, while in multivariate linear regression analysis, the factors which were significantly associated with duration of hospital stay included; duration of symptoms <2 weeks prior to admission (p = 0.008, beta = -0.247) and resistance to five antibiotic classes (p = 0.02, beta = 0.280). Conclusion: Close to 25% of the patients did not complete the treatment successfully. Most of the common bacterial isolates showed high level of resistance against the broad-spectrum antibiotics used as an empiric therapy. This is alarming. However, better sensitivity of common bacterial isolates against standardized first line treatment for empyema thoracis is promising.

Project description:BackgroundSepsis is one of the major causes of neonatal mortality in Pakistan. This study aimed to investigate the treatment outcomes, antibiotic use and its resistance pattern among neonatal sepsis patients attending a tertiary care hospital in Pakistan. We also aimed to identify the factors affecting mortality in neonatal sepsis patients.MethodsA descriptive, cross-sectional study was conducted in the pediatric wards of the Bahawal Victoria Hospital, Bahawalpur, Pakistan. All eligible neonatal sepsis patients who were registered at the study site from January 1, 2019 to June 30, 2019 were included in the study. The data collection form included information on patient's characteristics, antibiotic use and its sensitivity pattern, laboratory and microbiological data, and final treatment outcomes. Treatment outcomes included, discharged (with treatment success), leave against medical advice (LAMA), discharged on request (DOR) and death. Multivariable binary logistic regression analysis was used to find the independent factors associated with death. A p-value of less than 0.05 was considered statistically significant.ResultsAmong the total 586 patients, 398 (67.9%) were male, 328 (56%) were preterm, 415 (70.8%) were diagnosed with early onset sepsis, 299 (51%) were born with low birth weight. Most of the patients (n = 484, 82.6%) were treated with amikacin+cefotaxime at the start of treatment. Culture was positive in 52 (8.9%) patients and the most commonly identified bacteria included, Klebsiella species (n = 19, 36.5%) followed by E. coli (n = 15, 28.5%) and Staphylococcus aureus (n = 8, 15.4%). The identified bacterial isolates showed high level of resistance against the antibiotics initiated at the start of the treatment, while resistance against piperacillin+tazobactam, imipenem, vancomycin and linezolid was very low. Just under half of the patients (n = 280, 47.8%) successfully completed the treatment (i.e., discharged with treatment success), while 123 (21%) patients died during treatment. In multivariable binary logistic regression, the factors which still remained significantly associated with neonatal death included, preterm delivery (AOR 9.59; 95% CI 4.41, 20.84), sub-optimal birth weight (AOR 5.13; 95% CI 2.19, 12.04), early onset sepsis (AOR 2.99; 95% CI 1.39, 6.41) and length of hospital stay (AOR 0.76; 95% CI 0.67, 0.88).ConclusionThe mortality rate associated with sepsis was high in our study cohort. The bacterial isolates showed high level of resistance against the antibiotics started as the empiric therapy. Rational use of antibiotics can decrease the adverse outcomes in neonatal sepsis patients.

Project description:PurposeThis study investigates the knowledge, attitudes and practices of the general public regarding the use of antibiotics in community pharmacy, in Pakistan.MethodsThis 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.ResultsOver 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.ConclusionLevel 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.
