Medical practitioners' knowledge of dysentery treatment in Bangladesh

Prevalence of inappropriate antibiotic doses among pediatric patients of inpatient, outpatient, and emergency care units in Bangladesh: A cross-sectional study

The heterogeneous pediatric populations, their physiological differences, along with the necessity of performing additional dose calculation, make the pediatric population more vulnerable to the incidences of inappropriate antibiotic doses. This study was conducted to examine and evaluate the appropriateness of antibiotic doses. A cross-sectional study with a quantitative approach was conducted in three hospitals located in Savar from January 06, 2021 to October 17, 2022. This study had used a convenient sampling method to collect 405 filled prescription orders from heterogeneous pediatric patients prescribed by physicians from emergency, inpatient, and outpatient care units of various clinical settings. The Harriet Lane Handbook was used as reference to investigate inappropriate doses of antibiotics. Subsequently, all analyses were conducted using the RStudio 1.3.959 software. Binary logistic regression was used to assess the risk of inappropriate antibiotic prescription in pediatrics. The overall prevalence of inappropriate antibiotic dosing in pediatrics was 335 out of 545 (61.5%). Overdosing (36.3%) and oral antibiotic prescriptions (64%) were more common than underdosing (20.4%) and parenteral antibiotics (36%). The majority (230 out of 405, 56.8%) of pediatric patients had prescriptions with inappropriate antibiotic doses, with prevalence rates of 33.8% for inpatients, 86.7% for outpatients, and 50% for emergency pediatrics. The results also indicated that pediatric patients in outdoor and emergency care units, infants, toddlers, and early childhood, those prescribed two antibiotics simultaneously, and those receiving parenteral antibiotics, were less likely to have inappropriate antibiotic dosages in their prescriptions. This study demonstrated that about one out of every two prescriptions had inappropriate antibiotic doses; in particular, prescriptions containing only one antibiotic exhibited a substantial proportion of inappropriate antibiotic doses. Inappropriate antibiotic doses may result in therapeutic failure, patient harm, and antibiotic resistance. Good clinical pharmacy practice and careful adherence to pediatric dosing standards may minimize inappropriate antibiotic doses.

Knowledge, Attitude and Practice of Rural People on Antibiotic Usage: Bangladesh Perspective

Antibiotic resistance is a serious global health problem. This study endeavours to assess the current knowledge, attitude, and practice (KAP) regarding antibiotic usage among the rural people of Meherpur district, Bangladesh. This study followed quantitative approach and used social survey method to collect data from 399 respondents of Meherpur district. Results reveal that the respondents had a moderate knowledge of antibiotic usage but a negative attitude towards following the guideline and poor practice in using antibiotics made the situation worse for them. The findings of this study will help for the policymakers to develop the current awareness level of the rural people regarding antibiotic use and will provide a guideline for the improvement of current community clinics health-care providers’ efficiency on their service provision.

Intern doctors' views on the current and future antibiotic resistance situation of Chattagram Maa O Shishu Hospital Medical College, Bangladesh

BACKGROUND

Bacterial resistance due to antibiotic misuse is reported every day. Such threat calls for a consensus to develop new strategies to prevent the development of antibiotic resistance of bacteria. Medical doctors must play a pivotal role to control and prevent the misuse of antibiotics. There were complaints that prescribers are lacking behind in updates and advancement in the field. To address such knowledge gap, a study was conducted to know the views of interns on the current antibiotic resistance situation in a teaching hospital in Bangladesh.

METHODS

This study was a cross-sectional, randomized, and questionnaire-based survey. Interns of the medicine, gynecology, and surgery departments of Chattagram Maa O Shishu Hospital Medical College were the study population.

RESULTS

Out of 50 respondents, 98% would like more education on antibiotic selection. All respondents believed that prescribing inappropriate or unnecessary antibiotics was professionally unethical. Ninety percent of the participants were confident in making an accurate diagnosis of infection. Eighty-four percent of them were confident about dosage schedule. In all, 98% participants thought that antibiotic resistance is a national problem and 64% of the respondents thought that same problem also existed in their hospital. Study participants were of the view that 41%-60% of antibiotic usages are irrational in Bangladesh. Fifty-eight percent of the study population thought that antimicrobial resistance (AR) would be a greater problem in the future.

CONCLUSION

The interns believe that there is a knowledge gap on AR. More emphasis should be given to AR and its implications in the undergraduate curriculum. Latest national and international guidelines for antimicrobial therapy and resistance should be made available to the interns.

Frequently used healthcare services in urban slums of Dhaka and adjacent rural areas and their determinants

BACKGROUND

To compare patterns of healthcare service user preference between urban slums in Dhaka and adjacent rural areas and to identify key determinants of those preferences.

METHODS

The data were collected through baseline surveys conducted in 2008 and 2009. A total of 3207 subjects aged 10-90 years were systematically selected from 12 big slums in Dhaka and 3 rural villages outside Dhaka.

RESULTS

Two frequently used healthcare sources utilized in 1 month preceding the baseline survey were pharmacies (slum, 42.6%; rural, 30.1%) and government hospitals/clinics (GVHC; slum, 13.5%; rural, 8.9%). According to the multilevel logistic regression analysis adjusted for age, sex and marital status, the likelihood of using pharmacies and GVHC were higher for those subjects who used non-hygienic toilets, who reported food deficiency at a family level, who expressed dissatisfaction about family income and who stated poor health status. Some more factors namely overweight, living in permanently structured house, smoking bidis and less frequency of watching TV were associated with higher likelihood of using GVHC.

CONCLUSIONS

Pharmacy was the most dominant healthcare service in both areas. As persons running pharmacies often provide poor quality of healthcare services, they need continuous training and back-up supports to improve their quality of services and to strengthen the overall healthcare system in Bangladesh.

Informal sector providers in Bangladesh: how equipped are they to provide rational health care?

In Bangladesh, there is a lack of knowledge about the large body of informal sector practitioners, who are the major providers of health care to the poor, especially in rural areas, knowledge which is essential for designing a need-based, pro-poor health system. This paper addresses this gap by presenting descriptive data on their professional background including knowledge and practices on common illnesses and conditions from a nationwide, population-based health-care provider survey undertaken in 2007. The traditional healers (43%), traditional birth attendants (TBAs, 22%), and unqualified allopathic providers (village doctors and drug sellers, 16%) emerged as major providers in the health care scenario of Bangladesh. Community health workers (CHWs) comprised about 7% of the providers. The TBAs/traditional healers had <5 years of schooling on average compared with 10 years for the others. The TBAs/traditional healers were professionally more experienced (average 18 years) than the unqualified allopaths (average 12 years) and CHWs (average 8 years). Their main routes of entry into the profession were apprenticeship and inheritance (traditional healers, TBAs, drug sellers), and short training (village doctors) of few weeks to a few months from semi-formal, unregulated private institutions. Their professional knowledge base was not at a level necessary for providing basic curative services with minimum acceptable quality of care. The CHWs trained by the NGOs (46%) were relatively better in the rational use of drugs (e.g. use of antibiotics) than the unqualified allopathic providers. It is essential that the public sector, instead of ignoring, recognize the importance of the informal providers for the health care of the poor. Consequently, their capacity should be developed through training, supportive supervision and regulatory measures so as to accommodate them in the mainstream health system until constraints on the supply of qualified and motivated health care providers into the system can be alleviated.

Knowledge and practice of unqualified and semi-qualified allopathic providers in rural Bangladesh: implications for the HRH problem

OBJECTIVES

To explore current knowledge and practice of the unqualified/semi-qualified allopathic providers in the informal sector in rural Bangladesh to develop informed and need-based intervention for them.

METHODS

A cross-sectional descriptive survey was conducted in three conveniently selected sub-districts in the northern part of Bangladesh where a targeted poverty alleviation programme for the ultra poor was initiated in 2002. Semi-structured, pre-tested questionnaires were used to elicit information on socio-demographic, training and professional characteristics, and knowledge and practices on some common illnesses and conditions. Two-way and three-way cross-tabulations were done to compare and contrast the different groups, using SPSS PC+ ver.12.

RESULTS

The different groups of providers were found to possess superficial knowledge on the conditions they commonly provide services for. Differences were noted between the unqualified and semi-qualified providers with respect to knowledge and practice on common illnesses and conditions, and especially rational use of drugs and management of pregnancy and its complications.

CONCLUSION

Given the shortage of qualified healthcare professionals in rural Bangladesh, the importance of these informal providers should be recognized by the public sector, and their capacity developed in a planned way to improve their effectiveness and reduce irrational use of drugs.

Efficacy of pefloxacin in the treatment of patients with acute infectious diarrhoea

OBJECTIVE

To investigate the clinical and bacteriological efficacy of 5- and 7-day pefloxacin therapy in patients with acute infectious diarrhoea.

PATIENTS AND STUDY DESIGN

Eighty-two adult patients with acute infectious diarrhoea were randomly divided into three groups: group 1 (n = 20) received 5 days of treatment with pefloxacin, group 2 (n = 27) was assigned to a 7-day pefloxacin protocol, and group 3 (n = 35) was treated symptomatically. The daily dose of pefloxacin was 400mg orally. Clinical and bacteriological response was analysed on the third, fifth and seventh days of treatment as well as 1 and 4 weeks after the end of treatment. The study was an open-labelled, prospective clinical trial.

RESULTS

In the 47 patients (100%) of both pefloxacin groups a clinical improvement was noted on the third day compared with the control group, where this occurred on day 7. Bacteriological eradication was verified on the fifth day in 18 patients (90%) from group 1 and in 25 patients (93%) from group 2; they all had negative stool cultures 1 and 4 weeks after therapy was completed. Only 22 patients (63%) in the control group had negative stool cultures on the seventh day of treatment, but 4 weeks later all of them were negative.

CONCLUSION

There was no difference in clinical (p = 0.232) and bacteriological (p = 0.972) efficacy between the 5- and 7-day pefloxacin treatment protocols. However, both protocols differed significantly in clinical improvement (p < 0.001) and bacteriological eradication (p = 0.017) from the control group.

Community pharmacists' knowledge and dispensing recommendations for treatment of acute diarrhoea in Trinidad, West Indies

Using a hypothetical case presentation of a patient with acute diarrhoea, community pharmacists in Trinidad were asked about their knowledge and dispensing recommendations to manage acute diarrhoea. Oral rehydration salts (ORS) were recommended by 86% (79), but more pharmacists would recommend ORS as the first choice therapy alone, for children (70%) than adults (33%) (p < 0.01). Antimotility agents as a first choice therapy alone or with ORS would be given to more adults (60%) than children (10%) (p < 0.01), and more adults (59%) than children (33%) would receive cotrimoxazole. Pharmacists (93%) would counsel on preparation, storage and treatment schedule for ORS, but not on discontinuing (32%) or continuing ORS (4%). Despite 51 pharmacists knowing the WHO guidelines to treat acute diarrhoea, only 23 dispensed in accordance. Educational re-enforcement to manage acute diarrhoea and dispensing practices of medications are necessary for pharmacists who are the first patient contact in Trinidad.

Multicenter, randomized, double blind clinical trial of short course versus standard course oral ciprofloxacin for Shigella dysenteriae type 1 dysentery in children

BACKGROUND

Shigella dysenteriae type 1 (Sd1) dysentery is associated with serious morbidity and mortality. Treatment is either costly or complicated by the emergence of bacterial resistance. This study compared the efficacy and safety of short course (3 days) and standard course (5 days) oral ciprofloxacin in children with Sd1 dysentery.

METHODS

A multicenter, randomized, double blind, controlled clinical trial. Children between 1 and 12 years of age with Sd1 dysentery were randomized to receive oral ciprofloxacin suspension 15 mg/kg every 12 h for 3 days followed by placebo for 2 days or ciprofloxacin suspension for 5 days. Treatment success was defined as either resolution of illness or marked improvement on Day 6 of study. Bacteriologic cure was defined as failure to grow Sd1 on a stool sample collected on Day 6. Clinical assessments and joint examinations were performed at baseline, at discharge and 2 weeks later.

RESULTS

Of 253 patients enrolled 128 were assigned to short course ciprofloxacin and 125 to standard course ciprofloxacin. The success rates were 65 and 69% for short and standard course ciprofloxacin, respectively. All patients had bacteriologic cure, and all Sd1 isolates were susceptible to ciprofloxacin. No bacteriologic relapses occurred during the study period. Eight patients reported arthralgia. All patients had normal joint function including at follow-up.

CONCLUSION

In this study twice daily ciprofloxacin for 3 days achieved clinical cure rates similar to those for the same dosage given for 5 days in children with Sd1 dysentery.

Antibiotic medication and bacterial resistance to antibiotics: a survey of children in a Vietnamese community

OBJECTIVE

To investigate antibiotic use and antibiotic susceptibility of respiratory tract pathogens in children aged 1-5 years in Bavi, Vietnam.

METHOD

Nasopharynx and throat specimens were collected from 200 children from randomly selected households in a demographically defined population. Respiratory isolates were tested for antibiotic susceptibility according to the standard disk diffusion method. A questionnaire survey of carers elicited information on type of antibiotic used, duration of treatment, where the antibiotics had been purchased, type of treatment information retained by carers and episodes of illness preceding the study.

RESULTS

82% of the children had at least one symptom of acute respiratory tract infection (ARI) in the 4 weeks prior to the study, and of these 91% were treated with antibiotics. The most commonly used antibiotics were ampicillin (74%), penicillin (12%), amoxicillin (11%), erythromycin (5%), tetracycline (4%) and streptomycin (2%). Ampicillin was used for 3.3 days on average (SD:1.8) and penicillin for 2.6 days (SD:0.7). When deciding which antibiotic to use, 67% of the carers consulted the pharmacy seller, 11% decided themselves and 22% followed the doctor's prescription. The carrier rate of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis was 50%, 39% and 17%, respectively. Isolates from 145 children were susceptibility tested, and 74% were found to carry resistant pathogens. Of the tested isolates, 90% of S. pneumoniae, 68% of H. influenzae and 74% of M. catarrhalis were resistant to at least one antibiotic. The mean number of antibiotics (susceptible strains excluded) to which resistance was found was 2.0 (SD:1.2), 2.5 (SD:1.8) and 2.1 (SD:0.9), respectively. S. pneumoniae and H. influenzae showed high resistance to tetracycline (88% and 32%, respectively), trimethoprim/sulphonamide (32% and 44%), and chloramphenicol (25% and 24%). 23% of S. pneumoniae were erythromycin-resistant and 18% of H. influenzae isolates were resistant to ampicillin. There was a significant difference in ampicillin and penicillin resistance between the group of children previously treated with beta lactam antibiotics and the group of children who did not receive antibiotics.

CONCLUSION

As reported by the carers, children in Bavi are treated with antibiotics frequently. Most antibiotics were obtained without consulting a doctor. High levels of antibiotic resistance and high prevalence of multidrug-resistant strains were found among respiratory pathogens. The existence of a large reservoir of resistance genes among children in low-income countries represents a threat to the success of antibiotic therapy throughout the world. Multi-faceted programmes to improve rational use of antibiotics in Vietnam are urgently needed.

Are postal questionnaire surveys of reported activity valid? An exploration using general practitioner management of hypertension in older people

BACKGROUND

Postal questionnaire surveys are commonly used in general practice and often ask about self-reported activity. The validity of this approach is unknown.

AIM

To explore the criterion validity of questions asking about self-reported activity in a self-completion questionnaire.

METHOD

A comparison was made between (a) the self-reported actions of all general practitioner (GP) principals in 51 general practices randomly selected within the nine family health services authorities of the former northern regional health authority, and (b) the contents of the medical records (case notes and computerized records) of patients classified as hypertensive from a 1 in 7 random sample of all patients registered in these practices and aged between 65 and 80. Data were gathered from the GPs by self-completion postal questionnaires. Six comparisons were made for two groups of items: first, target and achieved blood pressure; secondly, patient's weight, smoking status, alcohol consumption, exercise and salt intake. The frequency with which the data items were recorded in patient records was compared with the GPs' self-reported frequency of performing the actions.

RESULTS

No relationship was found between achieved blood pressure and stated target levels. For each of the other actions, more than half of the responders reported that they usually or always performed the activity. For four of these (smoking, weight, alcohol and exercise), a significant association was noted, but the size of this varied considerably.

CONCLUSIONS

There is a variable relationship between what responders report that they do in self-completion questionnaires, and what they actually do as judged by the contents of their patients' medical records. In the absence of prior, knowledge of the validity of questions on reported activity, or of concurrent attempts to establish their validity, the questions should not be asked.

Socioeconomic and behavioral factors leading to acquired bacterial resistance to antibiotics in developing countries

In developing countries, acquired bacterial resistance to antimicrobial agents is common in isolates from healthy persons and from persons with community-acquired infections. Complex socioeconomic and behavioral factors associated with antibiotic resistance, particularly regarding diarrheal and respiratory pathogens, in developing tropical countries, include misuse of antibiotics by health professionals, unskilled practitioners, and laypersons; poor drug quality; unhygienic conditions accounting for spread of resistant bacteria; and inadequate surveillance.

Patterns of antimicrobial use and antimicrobial resistance among healthy children in Bolivia

OBJECTIVE

To determine the incidence of antimicrobial-resistant, nonpathogenic Escherichia coli among healthy children aged 6-72 months in Camiri town and a rural village, Javillo, in south-eastern Bolivia.

METHOD

A community-based survey: stool samples were obtained from 296 healthy children selected by modified cluster sampling in Camiri and all 25 eligible children in Javillo. E. coli isolates were tested for antimicrobial susceptibility according to the standard disc diffusion method. By a questionnaire survey of 12 pharmacies and by using simulated patients, we investigated the antimicrobial availability and the usage patterns in Camiri town.

RESULTS

In Camiri, over 90%, and in Javillo over 70% of children carried E. coli resistant to ampicillin, trimethoprim-sulphamethoxazole (TMP/SMX) or tetracycline. Overall, 63% of children carried E. coli with multiple resistance to ampicillin, TMP/SMX, tetracycline and chloramphenicol. In the simulated patients study, antimicrobials were dispensed inappropriately for 92% of adults and 40% of children with watery diarrhoea, and were under-prescribed for males with urethral discharge (67%) or females with fever and dysuria (58%). The dose and/or duration of antimicrobials dispensed was almost always too low.

CONCLUSION

Our study showed a disturbingly high prevalence of carriage of nonpathogenic E. coli resistant to antimicrobials. The prevalence of resistance to ampicillin and TMP/SMX was higher than that previously reported in developing countries. The existence of a large reservoir of resistance genes in healthy individuals in developing countries represents a threat to the success of antimicrobial therapy throughout the world. Programmes to improve rational and effective drug use in developing countries are urgently needed.
