In the last three decades, Clostridium difficile infection (CDI) has increased in incidence and severity in many countries worldwide. The increase in CDI incidence has been particularly apparent among surgical patients. Therefore, prevention of CDI and optimization of management in the surgical patient are paramount. An international multidisciplinary panel of experts from the World Society of Emergency Surgery (WSES) updated its guidelines for management of CDI in surgical patients according to the most recent available literature. The update includes recent changes introduced in the management of this infection.

In the last two decades there have been dramatic changes in the epidemiology of Clostridium difficile infection (CDI), with increases in incidence and severity of disease in many countries worldwide. The incidence of CDI has also increased in surgical patients. Optimization of management of C difficile, has therefore become increasingly urgent. An international multidisciplinary panel of experts prepared evidenced-based World Society of Emergency Surgery (WSES) guidelines for management of CDI in surgical patients.

Among patients with septic shock who receive appropriate initial antibiotic treatment, acquisition of infection in the intensive care unit and severity of illness appear to be the most important determinants of clinical outcome.

Routine use of prolonged infusion of time-dependent antibiotics for the empiric treatment of gram-negative bacterial infections offers no advantage over intermittent infusion antibiotic therapy with regard to treatment success, mortality, or hospital length of stay. These results were confirmed after controlling for potential confounders in a multivariate analysis.

In 2000, the Society of Critical Care Medicine (SCCM) and the American College of Clinical Pharmacy (ACCP) published a position paper that defined critical care pharmacy services as fundamental, desirable, and optimal. A task force was developed that included individuals who are members of the ACCP Critical Care Practice and Research Network, the SCCM clinical pharmacy and pharmacology section, and the American Society of Health‐System Pharmacists to develop an opinion paper with three primary objectives: to provide recommendations for the level of preparation and training of pharmacists to practice in critical care, to develop recommendations for the credentialing of pharmacists providing critical care services, and to develop mechanisms for documenting and justifying intensive care unit (ICU) pharmacy services. Each objective was addressed to accommodate the levels of services defined as fundamental, desirable, or optimal, and are targeted at all pharmacists providing or wanting to provide pharmacy services to critically ill patients. The training and preparing of the pharmacist caring for critically ill patients is discussed in the context of the knowledge and skills required to provide pharmacy services in the ICU. Credentialing of the critical care pharmacist and the documentation of services take into account the various scopes of practice, and recommendations are based on current and idealistic mechanisms. A detailed outline is provided for the process of services justification. This paper provides a foundation that is focused on delivering direct and proactive patient care services, particularly at the desirable and optimal levels, with the ultimate goal of enhancing the level of pharmacy services provided to the care of critically ill patients. This commentary should be of interest to numerous stakeholders including pharmacists, other pharmacy department staff, other ICU health care professionals, hospital and academic administrators, accrediting agencies, government officials, and payers. The task force encourages the profession of pharmacy in general to incorporate key recommendations provided in this document with respect to specialized training, credentialing, and service justification.

Objective. To examine perceived motivating factors and barriers (MFB) to postgraduate training (PGT) pursuit among pharmacy students. Methods. Third-year pharmacy students at 13 schools of pharmacy provided demographics and their plan and perceived MFBs for pursuing PGT. Responses were characterized using descriptive statistics. Kruskal-Wallis equality-of-proportions rank tests determined if differences in perceived MFBs existed between students based on plan to pursue PGT. Results. Among 1218 (69.5%) respondents, 37.1% planned to pursue PGT (32.9% did not, 30% were undecided). Students introduced to PGT prior to beginning pharmacy school more frequently planned to pursue PGT. More students who planned to pursue PGT had hospital work experience. The primary PGT rationale was, "I desire to gain more knowledge and experience." Student debt was the most commonly cited barrier. Conclusion. Introducing pharmacy students early to PGT options and establishing work experiences in the hospital setting may increase students' desire to pursue PGT.

BackgroundAntibiotics are commonly administered to hospitalized patients with infiltrates for possible bacterial pneumonia, often leading to unnecessary treatment and increasing the risk for resistance emergence. Therefore, we performed a study to determine if an enhanced antibiotic de-escalation practice could improve antibiotic utilization in mechanically ventilated patients with suspected pneumonia cared for in an academic closed intensive care unit (ICU).MethodsThis was a prospective cross-over trial comparing routine antibiotic management (RAM) and enhanced antimicrobial de-escalation (EAD) performed within two medical ICUs (total 34 beds) at Barnes-Jewish Hospital, an academic referral center. Patients in the EAD group had their antibiotic orders and microbiology results reviewed daily by a dedicated team comprised of a second-year critical care fellow, an ICU attending physician and an ICU pharmacist. Antibiotic de-escalation recommendations were made when appropriate based on microbiologic test results and clinical response to therapy.ResultsThere were 283 patients evaluable, with suspected pneumonia requiring mechanical ventilation: 139 (49.1%) patients in the RAM group and 144 (50.9%) in the EAD group. Early treatment failure based on clinical deterioration occurred in 33 (23.7%) and 40 (27.8%) patients, respectively (P = 0.438). In the remaining patients, antimicrobial de-escalation occurred in 70 (66.0%) and 70 (67.3%), respectively (P = 0.845). There was no difference between groups in total antibiotic days ((median (interquartile range)) 7.0 days (4.0, 9.0) versus 7.0 days (4.0, 8.8) (P = 0.616)); hospital mortality (25.2% versus 35.4% (P = 0.061)); or hospital duration (12.0 days (6.0, 20.0) versus 11.0 days (6.0, 22.0) (P = 0.918).ConclusionsThe addition of an EAD program to a high-intensity daytime staffing model already practicing a high-level of antibiotic stewardship in an academic ICU was not associated with greater antibiotic de-escalation or a reduction in the overall duration of antibiotic therapy.Trial registrationClinicalTrials.gov, NCT02685930.
