Comparative Study
A Retrospective Study on the Protective Effects of Topical Vancomycin in Patients Undergoing Multilevel Spinal Fusion.
Topical vancomycin may be an effective intervention to decrease the risk of postoperative surgical site infections (SSIs). The primary objective of this study was to evaluate the impact of topical vancomycin with intravenous (IV) cefazolin compared with IV cefazolin alone on the incidence of SSI in instrumented multilevel spinal fusion (MLSF) surgery. ⋯ Topical vancomycin administered in addition to IV cefazolin was associated with a decreased risk of SSI in high-risk MLSF patients. Female patients and those with diabetes mellitus were at higher risk of developing postsurgical infection. Further prospective studies are needed to confirm these results and to define the most clinically effective dose of topical vancomycin in this patient population.

Inhaled long-acting bronchodilators are commonly used as maintenance therapy in chronic obstructive pulmonary disease (COPD). We compared the risk of cardiovascular and cerebrovascular events among patients with COPD treated with inhaled long-acting bronchodilator monotherapy and combination therapy. ⋯ Our results suggest similar cardiovascular and cerebrovascular safety of LABA and LAMA when agents are used alone. Additional studies are needed to rule out potential risk associated with inhaled long-acting bronchodilator combination therapy.

Transgender and transsexual individuals have unique health care needs and risks compared with the population at large. It is estimated that 1 in 100,000 individuals in the United States is a transgender woman and 1 in 400,000 is a transgender man, although these estimates of prevalence are likely conservative. Transgender individuals are at an increased risk of tobacco, alcohol, and substance abuse; they have an increased lifetime suicide attempt risk; and they are more likely to experience significant stressors in their lives. ⋯ It is also essential to be able to identify transgender and transsexual patients correctly within electronic health records to ensure that appropriate care and monitoring are provided. For pharmacists, this means they should know the biologic sex for performing calculations such as creatinine clearance and to prevent teratogenic agents from reaching a transgender or transsexual man who could be pregnant or is capable of becoming pregnant. Promoting knowledge of transgender health issues will enable pharmacists to provide better, more holistic care to their transgender patients.

Although antimicrobials are commonly used in children, it is important to remember that they can have a profound impact on this unique patient population. Inadvertent consequences of antiinfective use in children include antimicrobial resistance, infection caused by Clostridium difficile, increased risk of obesity, and adverse drug events. In addition, compared with adults, children have different dosing requirements, antimicrobial formulation needs, pharmacokinetics, and antimicrobial susceptibility profiles. ⋯ In general, the interventions resulted in decreased antimicrobial use, reduced antimicrobial costs, and fewer prescribing errors. Children have unique medical needs related to antimicrobials and deserve focused ASP efforts. The literature regarding pediatric antimicrobial stewardship interventions is limited, but published interventions may serve as paradigms for developing pediatric ASPs as demonstrated by the general success of these interventions.

Augmented renal clearance (ARC) has been reported in approximately 30-65% of patients in the intensive care unit (ICU) despite the presence of a normal serum creatinine concentration. In certain ICU patient populations (e.g., patients with sepsis or trauma), the incidence increases to roughly 50-85%. Risk factors for ARC include the following: age younger than 50-55 years, male sex, higher diastolic blood pressure, fewer comorbidities, and a lower Acute Physiology and Chronic Health Evaluation II (APACHE II) or modified Sequential Organ Failure Assessment (SOFA) score at ICU admission. ⋯ In addition, an 8-hour continuous urine collection should be considered to assess a measured creatinine clearance for evaluating the necessity of medication dosage adjustments. There is a clear association between ARC and subtherapeutic antibiotic concentrations as well as literature suggesting worse clinical outcomes; thus, the risk of underdosing antibiotics in a patient with ARC could increase the risk of treatment failure. This review examines strategies to overcome ARC and summarizes current pharmacokinetic and pharmacodynamic literature in patients with ARC in an effort to provide dosing guidance for this patient population.
