Electrolyte Analysis and Replacement: Challenging a Paradigm in Surgical Patients.

Postoperative patients are susceptible to alterations in electrolyte homeostasis. Although electrolytes are replaced in critically ill patients, stable asymptomatic non-intensive care unit (ICU) patients often receive treatment of abnormal electrolytes. We hypothesize there is no proven benefit in asymptomatic patients. In 2016, using the electronic medical records and pharmacy database at a university academic medical center, we conducted a retrospective cost analysis of the frequency and cost of electrolyte analysis (basic metabolic panel [BMP], ionized calcium [Ca], magnesium [Mg], and phosphorus [P]) and replacement (potassium chloride [KCl], Mg, oral/iv Ca, oral/iv P) in perioperative patients. Patients without an oral diet order, with creatinine more than 1.4, age less than 16 years, admitted to the ICU, or with length of stay of more than 1 week were excluded. Nursing costs were calculated as a fraction of hourly wages per laboratory order or electrolyte replacement. One hundred thirteen patients met our criteria over 11 months. Mean length of stay was 4 days; mean age was 54 years; and creatinine was 0.67 ± 0.3. Electrolyte analysis laboratory orders (n = 1,045) totaled $6,978, and BMP was most frequently ordered accounting for 36% of laboratory costs. In total, 683 doses of electrolytes cost the pharmacy $1,780. Magnesium was most frequently replaced, followed by KCl, P, and Ca. Nursing cost associated with electrolyte analysis/replacement was $7,782. There is little evidence to support electrolyte analysis and replacement in stable asymptomatic noncritically ill patients, but their prevalence and cost ($146/case) in this study were substantial. Basic metabolic panels, pharmacy charges for potassium, and nursing staff costs accounted for the most significant portion of the total cost. Considering these data, further research should determine whether these practices are warranted.

Development of a Coprecepting Model for a Preceptor-in-Training Program for New Practitioners.

Background: Preceptor development is a focus of pharmacy residency programs across the country. Graduation from residency into the role of preceptor can be a challenge, as it is one of many transitions junior practitioners make in their early careers. Literature in recent years has brought attention to the need to establish preceptor development programs that adequately allow newer preceptors to develop their skills in experiential education, for both pharmacy residents and students. Furthermore, many preceptor development programs as implemented are often didactic in nature, and include readings, webinars, and other passive learning regarding the art of precepting. Objective: Given the need to develop a preceptor development program in our service line that met the needs of preceptors-in-training and full preceptors, we offer a description of our preceptor development program in the intensive care unit. Methods: We focused on active development of preceptor skills for multiple layers of resident and student learners. In addition, this model incorporated instructing, modeling, coaching, and facilitating, as the relationship between full preceptor and preceptor-in-training evolved. It also offered the opportunity for real-time feedback and discussion on precepting performance. Conclusions: We describe our coprecepting model as an opportunity that succeeded for us in helping to transition our preceptors-in-training to full preceptors. It met the needs of our department, staff, and patients, and we believe it has the potential to be valuable as a tool extrapolated to the preceptor development programs of other institutions.

The role of nonsteroidal anti-inflammatory drugs in pediatric patients.

Like in the adult population, nonsteroidal anti-inflammatory drugs (NSAIDS) are commonly used agents for their anti-inflammatory, anti-pyretic and analgesic effects in pediatrics. They are also used for some distinct indications in pediatrics such as Kawasaki disease, patent ductus arteriosus (PDA) closure, and Juvenile Idiopathic Arthritis (JIA). The primary mechanism thought to cause their therapeutic effects is the inhibition of prostaglandin synthesis. NSAIDs inhibit cyclooxygenase (COX) which is an enzyme that is necessary for the formation of prostaglandins. Unfortunately, this same mechanism, the inhibition of prostaglandins, is thought to be the most likely cause of gastrointestinal (GI) mucosal damage, because prostaglandins through multiple mechanisms assist in the preparation and maintenance of the protective barrier of the mucosal lining of the stomach. Similarly, prostaglandins in the kidney promote intrarenal plasma flow and electrolyte balance. The efficacy and safety of NSAIDs must be considered in prescribing these agents. The real conundrum of these therapies is determining the role of newer agents such as intravenous ibuprofen compared to existing alternatives. Available data for intravenous ibuprofen in adults is promising, but further studies are needed in pediatric patients to determine efficacy, place in therapy, and safety.

Efficacy and safety of ibuprofen and acetaminophen in children and adults: a meta-analysis and qualitative review.

OBJECTIVE: To evaluate the analgesic and antipyretic efficacy and safety of ibuprofen compared to acetaminophen in children and adults. DATA SOURCES: Literature searches were performed using PubMed/MEDLINE (through August 2009) and EMBASE (through January 2008) and were restricted to the English language. In PubMed/MEDLINE, search terms used were ibuprofen, acetaminophen, paracetamol, clinical trials, and randomized controlled trials. EMBASE search terms included ibuprofen and acetaminophen, restricted to human and clinical trials. STUDY SELECTION AND DATA EXTRACTION: All English-language articles identified from the data sources were reviewed. Multiple review articles were studied for any pertinent references and this yielded additional articles. Only articles that directly compared ibuprofen and acetaminophen were eligible for this review. DATA SYNTHESIS: Eighty-five studies that directly compared ibuprofen to acetaminophen were identified; 54 contained analgesic efficacy data, 35 contained antipyretic/temperature reduction data, and 66 contained safety data (some articles contained more than 1 type of data). Qualitative review of the literature revealed that, for the most part, ibuprofen was more efficacious than acetaminophen for the treatment of pain and fever in both pediatric and adult populations, and that these 2 drugs were equally safe. Meta-analyses on the subset of randomized clinical trial articles that reported sufficient quantitative information to calculate either an odds ratio (adverse event [AE]) or standardized mean difference (pain and fever) confirmed the qualitative results for adult (standardized mean difference [SMD] 0.69; 95% CI 0.57 to 0.81) and pediatric (SMD 0.28; 95% CI 0.10 to 0.46) pain at 2 hours postdose and pediatric fever (SMD 0.26; 95% CI 0.10 to 0.41) at 4 hours postdose. Conclusions regarding adult fever/temperature reduction could not be made due to a lack of evaluable data. The combined odds ratio for the proportion of adult subjects experiencing at least 1 AE slightly favored ibuprofen; however, the difference was not statistically significant (1.12; 95% CI 1.00 to 1.25). No significant difference between drugs in AE incidence was found for pediatric patients (0.82; 95% CI 0.60 to 1.12). CONCLUSIONS: Ibuprofen is as or more efficacious than acetaminophen for the treatment of pain and fever in adult and pediatric populations and is equally safe.
