Insulin Bolus Calculator: Lessons Learned from Institutional Experience

Insulin bolus calculators have proven effective in improving glycemia and patient safety. Insulin calculators are increasingly being implemented for inpatient hospital care. Multidisciplinary teams are often involved in the design and review of the efficacy and utilization for these calculators. At times, unintended consequences and benefits of utilization are found on review. Integration of our insulin calculator into our electronic health record system was a multidisciplinary effort. During implementation, several obstacles to effective care were identified and are discussed in the following manuscript. We describe the barriers to utilization and potential pitfalls in clinical integration. We further describe benefits in patient education, time of insulin administration versus meal delivery, variations in insulin bolus for ketone correction, variation in care, and maximum bolus administration. Sharing lessons learned from experiences using electronic insulin calculator order sets will further our goals of improved patient care in the hospital setting.

Characterization of Admission Medication Reconciliations Performed by Pharmacists in a Pediatric Institution: Resource Allocation

BACKGROUND

Compared with adults, children may be at greater risk of medication errors and potential adverse effects. The American Academy of Pediatrics recommends developing mechanisms for proactively identifying patients at risk for medication-related adverse events and failed reconciliation. This study's primary purpose was to evaluate pediatric patients admitted to identify risk factors requiring pharmacist intervention during medication reconciliation (MedRec).

METHODS

This prospective study included pediatric patients admitted during the study time frame until the target population of 500 patient encounters was achieved. During each admission, pharmacy staff completed a medication history, after which a pediatric pharmacist completed a MedRec, as is standard hospital practice. The primary outcome was identification of factors for high-risk transitions of care during pediatric admissions based on the need for pharmacist interventions during the MedRec process.

RESULTS

In total, 331 interventions were made for 127 patients (median 2; range, 1–12). Of the 331 interventions, 196 (59.2%) were classified as being of moderate or significant severity. Although patients with at least 2 home medications were significantly more likely to require any intervention (p < 0.0001), patients with 5 or more home medications were more likely to have a significant intervention.

CONCLUSION

Identifying patients with home medications could allow for focused efforts to intervene. Also, patients admitted to the PICU or those with cardiology- or endocrinology-related diagnoses should be prioritized for MedRec process, because of the likelihood of requiring multiple home medications. This strategy should be tailored to individual pediatric institutions based on internal quality control assessments and available resources.

Perceptions of the two-phase pharmacy residency match process

Purpose

To evaluate residency applicant (RA) and residency program director (RPD) perceptions of Phase II of the Match process since its inception in 2016.

Methods

An online survey was issued to all Match-registered RAs and RPDs for the 2016, 2017, and 2018 Match periods. Study participant demographics, participant designation (RA or RPD), the year(s) and Phase(s) of the Match participated in were measured using categorical ranges, and overall perceptions of the Match process since Phase II of the Match was implemented were captured with 5-point Likert scales.

Results

A total of 2,599 individuals (RA and RPD) completed the survey for an overall survey response rate of 12.6%. The majority of RAs were female (73.2%), under the age of 30 (87.4%), Caucasian (67.4%), and recently graduated (90.9% graduated between 2016 and 2018). Most RAs participated in the 2018 Match period (61%), and overall 82% successfully matched to a residency position. RA perceptions relating to process cost-effectiveness and perceived fairness to all applicants differed significantly from RPD perceptions (2.23 versus 3.71 and 2.80 versus 3.67, respectively; p < 0.001 for each). There were no differences between RA and RPD perceptions related to the submission/review process.

Conclusion

The Phase II of the Match process has demonstrated improved organization and satisfaction from the RPD perspective compared to the previous process. RAs have identified several areas for improvement in the process. It is imperative that efforts are made to continue expanding program and position offerings as much as possible.

Amikacin target achievement in adult cystic fibrosis patients utilizing Monte Carlo simulation

AIM

Pseudomonas aeruginosa (PsA) is a common pathogen in cystic fibrosis (CF). Management of an acute pulmonary exacerbation (APE) caused by PsA is dual anti-pseudomonal antibiotics, a beta-lactam plus aminoglycoside. Aminoglycoside dosing in CF differs from the general population due to altered pharmacokinetics. The primary objective of this study was to utilize pharmacokinetic data from adult CF patients that received amikacin to determine the probability of target attainment for APEs caused by PsA.

METHODS

This was a single-center, non-randomized, retrospective cohort study of patients >18 years with CF that received intravenous amikacin between January 2010 and July 2016. Amikacin dose, frequency, and serum concentrations were used to calculate pharmacokinetic parameters assuming a one-compartment model. Monte Carlo simulation was conducted with MIC values from CF patients with a PsA positive sputum culture between January 2014 and September 2016 to predict concentration-time profiles for different doses of amikacin.

RESULTS

This study included pharmacokinetic parameters for 14 amikacin courses administered to six unique patients. The average empiric dose of amikacin was 24.3 ± 14.6 mg/kg, achieving a peak:MIC ratio ≥8 at a rate of 37% (median 5.87; IQR 3.05-10.96). A dose of 45 mg/kg/day was needed to achieve target peak:MIC ratios 90% of the time for a PsA MIC of 8 mg/L.

CONCLUSION

Our data suggests it may not be clinically feasible to utilize amikacin for PsA isolates with a MIC of 16 mg/L. Current guideline dosing recommendations of amikacin 30-35 mg/kg/day are only adequate for PsA with a MIC ≤4 mg/L.

Second-Generation Antipsychotic Utilization and Metabolic Parameter Monitoring in an Inpatient Pediatric Population: A Retrospective Analysis

BACKGROUND

Second-generation antipsychotics (SGAs) are prescribed for a variety of indications and are strongly associated with adverse metabolic effects. Studies of pediatric outpatients have revealed several deficiencies in monitoring practices for adverse effects associated with SGAs.

OBJECTIVE

Our objective was to characterize SGA prescribing and metabolic parameter monitoring (MPM) in an inpatient pediatric population.

METHODS

Patients aged <18 years and discharged on SGA treatment between 1 November 2013 and 30 April 2014 from an inpatient psychiatric institution in Pittsburgh, PA, USA were included. Electronic medical records (EMRs) were reviewed for patient age and weight and for parameters used by the International Diabetes Federation (IDF) to define metabolic syndrome: waist circumference, fasting blood glucose, triglycerides, high-density lipoprotein, and blood pressure. The primary outcome was the percent of patients with completed MPM, defined as all parameters being available within the patient's EMR in any form, except estimates. Secondary outcomes included percent of patients with existing metabolic syndrome or obesity according to IDF criteria, average total daily dose of individual SGAs, and frequency of individual SGA utilization. Data were analyzed utilizing univariate descriptive statistics.

RESULTS

A total of 243 patients met inclusion criteria and were included in the analysis. For the primary outcome, 13.2% (n = 32) of patients had completed MPM for all parameters. Blood pressure was the most frequently documented parameter (n = 241; 99.2%), whereas waist circumference was the least (n = 67; 28%). Risperidone was the most commonly prescribed SGA (n = 99; 41%; average daily dose 1.92 mg).

CONCLUSIONS

Compared with outpatient studies, rates of documented MPM for certain parameters (i.e., fasting blood glucose, lipids) is higher for pediatric inpatients treated with SGAs. However, several monitoring deficiencies are still noted.
