Effectiveness of Surgical Prophylaxis Where the Antibiotic Resistance is High

ABSTRACT Objective: We aimed to investigate the risk factors for surgical site infections (SSI) and the effectiveness of prophylactic antibiotic use. Methods: The demographic characteristics, comorbidities, and microbiological examinations of patients diagnosed with SSI who had a cholecystectomy, vaginal hysterectomy, knee prosthesis, hip prosthesis, and gastric surgery between January the 1st, 2014 and December the 31st, 2019 were retrospectively analysed. The diagnosis of healthcare-associated infections and SSI was based on the Centers for Disease Control and Prevention criteria. Results: We detected Gram-negative bacteria in 30% of knee prosthesis infections (60% carbapenem-resistant), 60% of hip prosthesis infections (39% carbapenem-resistant), 36% of vaginal hysterectomy (no carbapenem resistance), 50% of cholecystectomy (no carbapenem resistance), and 20% of gastric surgery (no carbapenem resistance). Staphylococci were the causative agents in 30% of knee prosthesis infections (30% methicillin-resistant) and 20% of hip prosthesis infections (38% methicillin-resistant). Conclusion: We detected multidrug resistance in microorganisms isolated from knee and hip replacement infections. Antibiotic resistance is a big problem, and antibiotic prophylaxis is insufficient to prevent SSI. Doctors should follow up with the patient who underwent surgery closely and take microbiological samples to select appropriate antibiotics when SSI develops

Impact of antimicrobial drug restrictions on doctors' behaviors

Background/aim: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics.Materials and methods: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician.Results: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had 5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05).Conclusion: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did

Which method is best for the induction of labour?: A systematic review, network meta-analysis and cost-effectiveness analysis

Background: More than 150,000 pregnant women in England and Wales have their labour induced each year. Multiple pharmacological, mechanical and complementary methods are available to induce labour. Objective: To assess the relative effectiveness, safety and cost-effectiveness of labour induction methods and, data permitting, effects in different clinical subgroups. Methods: We carried out a systematic review using Cochrane methods. The Cochrane Pregnancy and Childbirth Group’s Trials Register was searched (March 2014). This contains over 22,000 reports of controlled trials (published from 1923 onwards) retrieved from weekly searches of OVID MEDLINE (1966 to current); Cochrane Central Register of Controlled Trials (The Cochrane Library); EMBASE (1982 to current); Cumulative Index to Nursing and Allied Health Literature (1984 to current); ClinicalTrials.gov; the World Health Organization International Clinical Trials Registry Portal; and hand-searching of relevant conference proceedings and journals. We included randomised controlled trials examining interventions to induce labour compared with placebo, no treatment or other interventions in women eligible for third-trimester induction. We included outcomes relating to efficacy, safety and acceptability to women. In addition, for the economic analysis we searched the Database of Abstracts of Reviews of Effects, and Economic Evaluations Databases, NHS Economic Evaluation Database and the Health Technology Assessment database. We carried out a network meta-analysis (NMA) using all of the available evidence, both direct and indirect, to produce estimates of the relative effects of each treatment compared with others in a network. We developed a de novo decision tree model to estimate the cost-effectiveness of various methods. The costs included were the intervention and other hospital costs incurred (price year 2012–13). We reviewed the literature to identify preference-based utilities for the health-related outcomes in the model. We calculated incremental cost-effectiveness ratios, expected costs, utilities and net benefit. We represent uncertainty in the optimal intervention using cost-effectiveness acceptability curves. Results: We identified 1190 studies; 611 were eligible for inclusion. The interventions most likely to achieve vaginal delivery (VD) within 24 hours were intravenous oxytocin with amniotomy [posterior rank 2; 95% credible intervals (CrIs) 1 to 9] and higher-dose (≥ 50 μg) vaginal misoprostol (rank 3; 95% CrI 1 to 6). Compared with placebo, several treatments reduced the odds of caesarean section, but we observed considerable uncertainty in treatment rankings. For uterine hyperstimulation, double-balloon catheter had the highest probability of being among the best three treatments, whereas vaginal misoprostol (≥ 50 μg) was most likely to increase the odds of excessive uterine activity. For other safety outcomes there were insufficient data or there was too much uncertainty to identify which treatments performed ‘best’. Few studies collected information on women’s views. Owing to incomplete reporting of the VD within 24 hours outcome, the cost-effectiveness analysis could compare only 20 interventions. The analysis suggested that most interventions have similar utility and differ mainly in cost. With a caveat of considerable uncertainty, titrated (low-dose) misoprostol solution and buccal/sublingual misoprostol had the highest likelihood of being cost-effective. Limitations: There was considerable uncertainty in findings and there were insufficient data for some planned subgroup analyses. Conclusions: Overall, misoprostol and oxytocin with amniotomy (for women with favourable cervix) is more successful than other agents in achieving VD within 24 hours. The ranking according to safety of different methods was less clear. The cost-effectiveness analysis suggested that titrated (low-dose) oral misoprostol solution resulted in the highest utility, whereas buccal/sublingual misoprostol had the lowest cost. There was a high degree of uncertainty as to the most cost-effective intervention

Anthrax during pregnancy: Case reports and review

We review, in detail, 2 cases of anthrax during pregnancy, its maternal and perinatal complications, and its management. Patient 1 was a 33-year-old woman at 32 weeks of gestation. She had a submandibular eschar; extensive edema on her face, neck, and upper thorax that inhibited respiratory function; and fever. The patient was treated with penicillin G and prednisolone after the diagnosis of anthrax. She recovered within 10 days but delivered a preterm baby. Patient 2 was a 29-year-old woman at 33 weeks of gestation. Her anthrax lesion was on her right elbow, and therapy consisted of procaine penicillin. She also delivered a preterm baby. These 2 cases show that anthrax during pregnancy can be successfully managed, but preterm delivery could be a complication

Maternal carriage and neonatal colonisation of group B streptococcus in eastern Turkey: prevalence, risk factors and antimicrobial resistance

Our object is to determine the prevalence of group B streptococcus (GBS) carriage among pregnant women, the neonatal colonisation rate and the antimicrobial susceptibility to formulate a policy for treatment and prevention regarding perinatal GBS diseases in eastern Turkey. A total of 150 pregnant women were screened for GBS colonisation. Samples were collected from the vagina and the rectum of pregnant women, and the ear canal, throat and umbilicus of the neonates of colonised mothers. Antimicrobial susceptibility of the isolates was also investigated. GBS was isolated in at least one specimen from the 150 women in 48 cases; it was estimated that, overall, about 32% of the pregnant women and 17.3% of overall newborns were colonised with GBS. The overall rate of GBS vertical transmission was 54.2% in this study. Maternal colonisation rate was significantly higher in younger ages (p < 0.01) when maternal age of 20 years was taken as a cut-off point. All isolates were found to be sensitive to penicillin, ampicillin, cefazolin and vancomycin. Resistance to erythromycin and clindamycin were found to be 13.5 and 2.7%, respectively
