Adherence to Antiretroviral Therapy for Pediatric HIV Infection: Review of the Literature and Recommendations for Research

This review described and compared empirical investigations of adherence to pediatric antiretroviral therapy (ART) and predictors/correlates of adherence with regard to methodology and outcome. Thirteen empirical studies of childrens adherence to ART, conducted between the years 1981 and 2002 were identified. Investigations varied by age of participant, drug therapy regimen, method of adherence assessment, and by the reporting of predictors/correlates of adherence. Conclusions from the literature are limited by the lack of common sample characteristics and adherence assessment methodologies. Nevertheless, consistent with much of the pediatric adherence literature, adherence to antiretroviral medications among children and adolescents appears to be frequently suboptimal. Few investigations identified predictors/correlates of adherence, but these appear generally similar to those found in adult samples. Recommendations for future investigations are proposed.

Nationwide Antibiogram Analysis Using NCCLS M39-A Guidelines

ABSTRACT Lack of standardization in antibiogram (ABGM) preparation (the overall profile of antimicrobial susceptibility results of a microbial species to a battery of antimicrobial agents) has not been addressed until recently. The objective of this study was to analyze current antibiograms using the recently published NCCLS M39-A guidelines for preparation of antibiograms to identify areas for improvement in the reporting of antibiogram susceptibility data. Antibiograms from across the United States were obtained by various methods, including direct mailings, Internet searches, and professional contacts. Each ABGM collected was analyzed using prospectively defined elements from the M39-A guidelines. Additionally, seven quality indicators were also evaluated to look for the reporting of any atypical or inappropriate susceptibility data. The 209 antibiograms collected from 149 institutions showed at least 85% compliance to 5 of the 10 M39-A elements analyzed. Clinically relevant elements not met included annual analysis, duplicate isolate notation, and the exclusion of organisms with fewer than 10 isolates. As for the quality indicators evaluated, unexpected results included the 7% of antibiograms that reported <100% vancomycin susceptibility for Staphylococcus aureus, 24% that had inconsistent beta-lactam susceptibility for Staphylococcus aureus, 20% that reported <100% imipenem susceptibility for Escherichia coli, and 37% that reported >0% ampicillin susceptibility for Klebsiella pneumoniae. These findings suggest that antibiograms should be reviewed thoroughly by infectious disease specialists (physicians and pharmacists), clinical microbiologists, and infection control personnel for identification of abnormal findings prior to distribution.

Effect of Duplicate Isolates of Methicillin-Susceptible and Methicillin-Resistant Staphylococcus aureus on Antibiogram Data

ABSTRACT Duplicate Staphylococcus aureus isolates were analyzed to determine the impact of multiple isolates from the same patient on annual antibiogram data. During a 6-year period (1996 to 2001), 3,227 patients with 4,844 S. aureus isolates were evaluated. A total of 39% of patients with methicillin-resistant S. aureus (MRSA) (n = 860) and 23% of patients with methicillin-susceptible S. aureus (MSSA) (n = 2,367) infections had duplicate isolates. Cumulative data show that 91% of the patients during this 6-year period with duplicate isolates (2 to 13 duplicates/year) did not switch between MSSA and MRSA but retained the original S. aureus strain whether it was MSSA or MRSA. Rates of MRSA were calculated for each year by using all isolates and then eliminating duplicates. The impact of duplicate MRSA and MSSA isolates was evaluated by using the ratio of isolates per patient such that ratios of >1.0 indicate >1 isolate per patient. The 6-year ratio for MRSA was 1.90 isolates/patient, and the ratio for MSSA was 1.35. A significant difference (P < 0.05) was noted in the MRSA rates in 4 of 6 years when duplicate isolates were removed. Common phenotypic antibiogram patterns were compared for all MRSA isolates during the 6-year period, and 64% were of a single antibiogram phenotype. Eighty-eight percent of patients with duplicate MRSA isolates had phenotypically identical multiple isolates. The rate of MRSA differs when duplicate isolates are removed from the antibiogram data.

Effects of a hospitalwide pharmacy practice model change on readmission and return to emergency department rates

PURPOSE The impact of an innovative medication reconciliation and discharge education program on 30-day readmissions and emergency department (ED) visits was evaluated. METHODS An observational pre-post analysis was conducted at an academic medical center to compare rates of hospital readmissions and return to ED visits during three-month periods before and after implementation of a restructured pharmacy practice model including (1) medication reconciliation at transitions of care for every patient and discharge education for a high-risk subgroup, (2) new or expanded services in the preanesthesia testing clinic and ED, (3) a medication reconciliation technician team, and (4) pharmacist-to-patient ratios of 1:30 on acute care floors and 1:18 on critical care units. The primary outcome was the composite of rates of readmissions and return to ED visits within 30 days of discharge. RESULTS A total of 3,316 patients were included in the study. Pharmacy teams completed medication reconciliation in 95.8% of cases at admission and 69.7% of cases at discharge. Discharge education was provided to 73.5% of high-risk patients (defined as those receiving anticoagulation therapy or treatment for acute myocardial infarction, chronic obstructive pulmonary disease, congestive heart failure, or pneumonia). No significant difference was observed between the preimplementation and postimplementation groups with regard to the primary outcome. In the high-risk subgroup, there was a significant reduction in the 30-day rate of hospital readmissions, which declined from 17.8% to 12.3% (p=0.042); cost projections indicated that this reduction in readmissions could yield annual direct cost savings of more than

Tolerability and outcome of once weekly liposomal amphotericin B for the prevention of invasive fungal infections in hematopoietic stem cell transplant patients with graft-versus-host disease

BackgroundMedication Reconciliation and Medication Safety are two themes emphasized in a variety of healthcare organizations. As a result, health care facilities have established methods for obtaining a patients medication history. However, these methods may vary among institutions or even among the health care professionals in a single institution, and studies have shown that patients are reluctant to disclose their complementary and alternative medicine use to any health care professional. This lack of disclosure is important in surgical patients because of potential herbal interactions with medications and drugs used during the surgical procedure; and the potential for adverse reactions including effects on coagulation, blood pressure, sedation, electrolytes or diuresis. Therefore, the objectives of this study are to identify patterns of natural product use, to identify potential complications among patients scheduled for surgery, to improve existing medication reconciliation efforts, and to develop discontinuation guidelines for the use of these products prior to surgery.MethodsA retrospective review of surgery patients presenting to the Anesthesia Preoperative Evaluation Clinic (APEC) at the University of Kansas Hospital was conducted to identify the prevalence of natural product use. The following data was collected: patient age; gender; allergy information; date of medication history; number of days prior to surgery; source of medication history; credentials of person obtaining the history; number and name of prescription medications, over-the-counter medications and natural products; and natural product dosage. Following the collection of data and analysis of the most common natural products used, possible complications and interactions were identified, and a protocol regarding the pre-operative use of natural products was developed and implemented.ResultsApproximately one-fourth of patients seen in the APEC indicated the use of natural products. Patients taking natural products were significantly older, were more likely to undergo cardiac or chest surgery, and were more likely to be taking more prescription and non-prescription medications (all p < 0.001).ConclusionBased on the results of this study, it is concluded that there is a need for established guidelines regarding discontinuation of selected natural products prior to surgery and further education is needed concerning the perioperative implications of natural products.

Effectiveness of Exogenous Albumin Administration for the Prevention of Ifosfamide-Induced Encephalopathy

Background Invasive fungal infections remain problematic in immunosuppressed allogeneic stem cell transplant recipients and the use of corticosteroids for the treatment of graft-versus-host-disease can increase the risk threefold. Although antifungal prophylaxis has been shown to decrease the incidence of infection, the optimal antifungal prophylactic regimen in this patient population has yet to be identified. Since early diagnosis of fungal infections might not be possible and the treatment of established fungal infections might be difficult and associated with high infection-related mortality, prevention has become an important strategy in reducing overall morbidity and mortality. While triazoles are the preferred agents, some patients are unable to tolerate them and an alternative drug is warranted. Objectives To assess the tolerability of once weekly liposomal amphotericin B as a prophylactic strategy in patients undergoing stem cell transplantation by evaluating any adverse events leading to its discontinuation. In terms of efficacy, to also compare the outcome and incidence of invasive fungal infections in patients who received amphotericin B, triazoles, and echinocandins. Results A total of 101 allogeneic transplant recipients receiving corticosteroids for the treatment of graft-versus-host-disease and antifungal prophylaxis were evaluated from August 2009 to September 2012. Liposomal amphotericin B 3 mg/kg intravenous once weekly was found to be well tolerated. The incidence of invasive fungal infections was 19%, 17%, and 7% in the liposomal amphotericin B, echinocandin, and triazole groups, respectively. Two deaths occurred in the liposomal amphotericin B group and one death occurred in the echinocandin group. None of the deaths were fungal infection related. Conclusion Antifungal prophylaxis with liposomal amphotericin B was well tolerated, but the incidence of invasive fungal infections in patients receiving liposomal amphotericin B was higher than other antifungal agents in this study. The optimal dose and schedule of liposomal amphotericin B for antifungal prophylaxis in this patient population are still not known and considering its broad spectrum activity, prospective trials in comparison to triazoles are warranted.

Implementation of standardized dosing units for i.v. medications

The Use of Individualized Pharmacist Performance Reports to Reduce Pharmacist-Related Medication Order Entry Errors Following Electronic Medical Record Implementation

PURPOSE The implementation of standardized dosing units for six i.v. medications at an academic medical center is described. SUMMARY During the implementation of an electronic health record system at an academic medical center, it was noticed that providers could order some i.v. medications in multiple dosing units, including epinephrine, isoproterenol, midazolam, nitroglycerin, norepinephrine, and phenylephrine. Possible options to standardize i.v. medications along with their pros and cons were presented for discussion to key providers in all of the intensive care units. Once the providers agreed on a solution, the information was presented to the pharmacy and therapeutics committee for final approval. A nursing education plan was created and administered before the standardization of dosing units was implemented. A nursing survey was conducted before and after implementation of dosing-unit standardization to determine the effectiveness of nursing education on compliance with the standardization of the dosing units for the listed medications. The survey was designed to evaluate, when given a choice, what dosing units nurses would use to administer epinephrine, isoproterenol, midazolam, nitroglycerin, norepinephrine, and phenylephrine. The decision was made by the key providers to use weight-based dosing-micrograms per kilograms per minute-to allow for consistency of use of these medications for pediatric and adult patients. Nursing education was completed to ensure that nurses were aware of how to safely administer these medications using the new dosing units. CONCLUSION Dosing-unit standardization for dose-adjustable i.v. infusions can provide improved consistency and decrease the potential for dosing errors when administering epinephrine, isoproterenol, midazolam, nitroglycerin, norepinephrine, and phenylephrine.

Corticosteroids for the management of immune-related adverse events in patients receiving checkpoint inhibitors:

Purpose To measure the impact of an individual pharmacist performance report (IPPR) program on pharmacist-related medication order entry errors (MOEEs) at an academic medical center. Methods The number and type of pharmacist-related MOEEs were collected at 2 different times: immediately following implementation of an electronic medical record (baseline) and following completion of the IPPR program. Three different collection methods were utilized to identify and categorize pharmacist-related MOEEs: 1) Patient Safety Net (PSN) incident reporting system, 2) manual event reporting, and 3) a nursing to pharmacy electronic messaging system. The IPPR program consisted of mandatory educational sessions for pharmacist staff. The program content focused on strategies to reduce pharmacist-related MOEEs identified in the baseline data collection period as well as an individualized report generated for each pharmacist having caused an MOEE that showed their performance compared to the departments performance. Results The percentage of event reports containing a pharmacist-related MOEE decreased from baseline to post IPPR program (13.7% and 6.3%, respectively; P < .001). In addition, the total number of pharmacist-related MOEEs was halved after the IPPR program (321 vs 148; P < .001). Significant reductions were noted in the following MOEE categories: duplicate orders, missed orders, wrong frequency, wrong dose, and other. Nonsignificant reductions were noted in errors related to no order and wrong drug. Conclusion Based on the observations and results of this study, it is proposed that individualized performance feedback can be a successful method to improve MOEE performance by pharmacists.
