Background: The objective of this review is to provide a comprehensive overview of the different types of economic evaluations that can be utilized by Infection Prevention and Control practitioners with a particular focus on the use of the quality adjusted life year, and its associated challenges. We also highlight existing economic evaluations published within Infection Prevention and Control, research gaps and future directions., Design: Narrative Review., Conclusions: To date the majority of economic evaluations within Infection Prevention and Control are considered partial economic evaluations. Acknowledging the challenges, which include variable utilities within infection prevention and control, a lack of randomized controlled trials, and difficulty in modelling infectious diseases in general, future economic evaluation studies should strive to be consistent with published guidelines for economic evaluations. This includes the use of quality adjusted life years. Further research is required to estimate utility scores of relevance within Infection Prevention and Control., Competing Interests: Not applicable.Has been obtained by all authors.The authors declare that they have no competing interests.Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Objectives: Antimicrobial stewardship programs (ASPs) promote the judicious use of antimicrobials by limiting inappropriate use. This article evaluates the impact of a prospective-audit-and-feedback ASP implementation on the appropriate utilization of carbapenems in a tertiary pediatrics and obstetrics/gynecology hospital in Singapore (KKH) after the establishment of an ASP in July 2011., Methods: This was a prospective, single-center, pre-post intervention study designed to analyze the appropriate prescribing of carbapenems pre-ASP (October 2009 to June 2011) and post-ASP (July 2011 to December 2013). Utilization of carbapenems was evaluated by daily defined doses (DDDs), days of therapy (DOTs), prescriptions, as well as cost per 100 patient-days pre-ASP and post-ASP using a segmented regression of interrupted time series analysis., Results: Of 404 prescriptions for carbapenems reviewed post-ASP, 70.3% were appropriate compared with those prescribed pre-ASP (55.9%; p=0.027). Reasons for inappropriate prescribing included inappropriate choice (36.1%) and duration (31.3%). A total of 61.2% of the interventions (213 of 348) were accepted. For pediatrics, there was a significant decrease in DDDs per 100 patient-days by 55.6% from a baseline of 0.9-0.4 (p=0.013) post-ASP and a reduction in DOTs per 100 patient-days by 46.7% from a baseline of 1.5-0.8 (p=0.06) post-ASP without significant changes in prescription rates. Pediatrics utilization cost increased from a pre-ASP mean of $175 per 100 patient-days to a peak of $238 (p<0.001) and decreased significantly post-ASP to a mean of $149 (p=0.01). For obstetrics/gynecology, there were no significant changes in DDDs (0.3 vs 0.3, p=0.99), DOTs (0.2 vs 0.3, p=0.36), prescriptions (0.03 vs 0.04, p=0.38), or cost ($45 vs $52, p=0.63) per 100 patient-days pre- versus post-ASP., Conclusions: ASPs improved the appropriateness of carbapenems prescribing overall and reduced utilization in pediatrics. Identification of areas of inappropriate prescribing will be valuable in guiding future ASP efforts., (© 2014 Pharmacotherapy Publications, Inc.)

Background: Various blood safety initiatives have ensured a historically low risk of infection transmission through blood transfusion. Although further prevention of infection transmission is possible through, for example, nucleic acid testing and future introduction of pathogen inactivation, such initiatives are very costly in relation to the benefit they offer. Although estimation of the cost-effectiveness requires detailed information about the survival of transfusion recipients, previous cost-effectiveness analyses have relied on incorrect survival assumptions., Study Design and Methods: Based on empirical data of more than 1 million Scandinavian transfusion recipients followed for up to 20 years, we present two new survival functions. In a fictitious example we assessed the impact of survival assumptions on the estimated costs per quality-adjusted life-year (QALY) gained, by using the survival functions of three previous cost-effectiveness analyses along with the two new survival functions., Conclusions: We conclude that despite considerable costs, previous cost-effectiveness studies may have underestimated the costs per QALY gained by as much as 44%.

Prescribing antibiotics for perioperative prophylaxis in common surgical procedures presents an ideal target for educational intervention. In this situation, antibiotics are often used inappropriately, with consequent excess expense and risk of morbidity. We developed an educational intervention aimed at the choice and appropriate dosing of antibiotics for the prophylaxis of cesarean sections. Person-to-person educational messages targeted at authoritative senior department members were supplemented by brief reminders on a structured antibiotic order form. Time-series analyses were conducted on 34 months of antibiotic use data for 2,783 cesarean sections to estimate the trend of magnitude and significance of discontinuities associated with the start of the program. Prior to the intervention, 95% of sections receiving prophylaxis were given cefoxitin and 3% were given cefazolin. After the intervention, these proportions were reversed, with the shift in use occurring immediately after the intervention (p less than .001). Two years after the intervention, virtually all patients undergoing cesarean sections who receive antibiotic prophylaxis are given cefazolin. Savings from this change alone accounted for over $26,000 each year, or $47.36 per patient-day of prophylaxis. Substantial changes in prescribing practices for routine procedures can be accomplished through the implementation of a coordinated educational program that enlists influential senior staff members in a department in which policy-making is highly centralized, coupled with a structured educational ordering system. Lasting improvements in clinical practices may be brought about by means that are noncoercive, inexpensive and well-accepted by medical staff.

We surveyed 1824 physicians to determine current newborn nursery (NBN) and neonatal intensive care unit (NICU) gowning procedures and the gowning preferences of NBN and NICU physicians. A total of 712 questionnaires (39.0%) were returned from 453 hospitals. Of the 712 questionnaire respondents, 251 (35.3%) thought that gowns should be worn at all times. However, 319 (72.8%) of the 438 NBNs and 317 (71.6%) of the 443 NICUs surveyed continue to require gowns at all times. The difference between gown preference and practice was statistically significant. Gowns were worn only for handling infants in 96 NBNs (21.9%) and 109 NICUs (24.6%), while 344 physicians (48.3%) preferred this regimen. Gowns were worn in 16 NBNs (3.7%) and 15 NICUs (3.4%) only for isolated infants, but 67 respondents (9.4%) believed this to be the procedure of choice. At our institution, 100 and 300 gowns are worn daily in the NBN and NICU, respectively, at a cost of +0.28 per gown use, generating an estimated yearly expense of +40 880. In addition, the current literature does not support gowning as a means of infection control in this setting.
