Impact of PCR for respiratory viruses on antibiotic use: theory and practice.

ABSTRACT:

Rationale for the study

Real-time polymerase chain reaction (PCR) for respiratory viruses is more sensitive, yet more expensive, than conventionally used direct immunofluorescence (DIF). We determined the impact of real-time PCR, additional to DIF, on antibiotic prescription in ventilated children with lower respiratory tract infection (LRTI) at admission to the pediatric intensive care unit (PICU).

Methods

First, a multicenter survey study was performed. Subsequently, in a prospective study, children (≤ 5 years) with LRTI were tested at admission by DIF and PCR. Positive DIF results were reported at the end of the first working day. PICU physicians reported antibiotic treatment on the second working day. After informing them of the PCR result antibiotic treatment was reevaluated.

Results

The multicenter survey study (94 respondents) showed that PCR decreased antibiotic use (P < 0.001). In the prospective study 38 children were included, of which 19 (50%) were DIF positive. Of the 19 DIF negative patients 12 (63%) were treated with antibiotics before revealing the PCR result; the PCR test was positive in 9 out of 12. Revealing PCR results did not alter antibiotic treatment. In 7 DIF negative patients antibiotics not given, the PCR test was positive.

Conclusion

In contrast to their responses to the survey study, in real-life PICU physicians did not let their antibiotic prescription be influenced by respiratory real-time PCR in children ventilated for LRTI.

Project description:BackgroundThe main objective of this study was to evaluate the antimicrobial therapy knowledge, attitudes, and practices of primary care physicians in the West Bank and Gaza.MethodsBetween January and April 2021, this cross-sectional survey was conducted. A link to the online survey was sent via confidential email lists to 336 primary care physicians who treated patients in Ministry of Health clinics. The survey questions scoring system was devised in order to evaluate the physicians' practice, knowledge, and attitudes. Our scoring system identified favorable (good) and unfavorable (average and poor) antibiotic practices. In addition to independent t-test, the Chi-square test was used to compare the two groups of physicians' knowledge, attitudes, and practices with their background characteristics. A multivariate analysis was performed to identify potential confounding variables having significant relationships.ResultsOf the 336 distributed questionnaires, 316 were completed, with a response rate of 94%. More than half (54.7%) were males, half (51.6%) were between 30 and 45 years of age, and most were general practitioners (74.1%). The overall good knowledge and attitude scores were 125 (39.6%) and 194 (61.4%), respectively. More than half (58.2%) had good antibiotic prescription practices. Females reported significantly more favorable practices than males, as did family medicine specialists compared with general practitioners. Finally, knowledge about antibiotic prescriptions had a substantial impact on changing their practices. However, physicians' attitudes toward antibiotic prescriptions did not have a significant role in shaping their practices.ConclusionOveruse of antibiotics is a significant health issue in Palestine and worldwide. Most physicians know that improper antibiotic usage can cause antimicrobial resistance. More than two-thirds avoided needless antimicrobial prescriptions. In practicing antimicrobial stewardship, most prescribed fewer antibiotics and did not prescribe because of patient pressure. Family medicine specialists, female doctors, and those with high knowledge scores regardless of caseload were more likely to have good practices.

Project description:BackgroundThe Danish antibiotic use guidelines for companion animal practice were published by the Danish Veterinary Association in 2012. Since then, national surveillance data indicate a 10% reduction in the total use of antibiotics for companion animals, particularly a marked reduction in the use of third generation cephalosporins. The aim of the study was to assess if and how the guidelines have impacted diagnostic and antibiotic prescription habits of the users, and to identify user perceived barriers to implementation.ResultsAn online questionnaire was sent to all 882 members of the Danish Small Animal Veterinary Association in October 2015. The survey was completed by 151 veterinarians. Respondents most frequently consulted the recommendations on skin and urinary tract infections (UTI), and users generally reported a high degree of adherence to the recommendations. Sixty-five per cent indicated that the guidelines had influenced their habits in one or more of the areas being investigated, i.e. perioperative use of antibiotics, use of first line antibiotics for the treatment of pyoderma or UTI, and/or use of microbiological diagnostics. Perioperative use of antibiotics for clean surgeries was uncommon, irrespective of whether respondents had consulted the relevant recommendations or not. On the contrary, significant differences in the prescribing habits between guideline users and non-users were observed for pyoderma and UTI, suggesting an impact of the guidelines towards more prudent antimicrobial use. The diagnostic habits were examined in a subgroup of 63 guideline users. Of those, 19 and 39% reported frequent use of culture and susceptibility (C&S) testing prior to treating pyoderma and UTI respectively, whereas 68-84% reported C&S testing in the event of poor response to treatment or recurrence of infections. The main barriers for implementation of therapeutic recommendations were confidence in old prescribing practices and unavailability of recommended drugs. The main barriers for C&S testing were good experience with empiric treatment, and the owners' financial situation.ConclusionsThe findings suggest a positive influence of the national antibiotic guidelines on prescription patterns among companion animal practitioners in Denmark. Sustained campaign activity is encouraged and should include promotion of bacteriological testing.
