Antimicrobial stewardship program to reduce antiretroviral medication errors in hospitalized patients with human immunodeficiency virus infection

Antiretroviral Stewardship: Top 10 Questions Encountered by Stewardship Teams and Solutions to Optimize Therapy

PURPOSE

Infectious disease pharmacists and physicians overseeing antimicrobial stewardship programs possess expertise and often advanced certification in management of antiretrovirals to treat HIV. Stewardship programs are responsible for managing facility formularies and must stay up to date with the latest antiretrovirals, including once daily formulations and depot injectables. Furthermore, stewardship program members need to understand drug-interactions, short-, and long-term toxicities of these regimens, including dyslipidemia and cardiovascular effects. Patients receiving chronic antiretroviral therapy may present to the acute care, ambulatory care, and long-term care settings. Like other antimicrobials, audit-and-feedback, drug monitoring, and dose-optimization are often required to prevent antiretroviral associated medication errors and minimize resistance.

METHODS

A narrative review was conducted on antiretroviral stewardship, addressing common clinical questions encountered by stewardship teams and best practices to optimize antiretroviral therapy and reduce the risk for treatment interruptions, resistance, drug interactions, long term toxicities, and other adverse effects.

FINDINGS

People living with HIV are often hospitalized and treated by medical teams without formal HIV training. For this reason, these patients are at greater risk for medication errors during hospitalization and between transitions of care. Many opportunities are present for antiretroviral stewardship to mitigate these errors. Frequent updates to simplify HIV regimen, maintain select patients on fixed-dose combination tablets, and strategies to minimize drug interactions make it difficult for even the seasoned clinician to keep up regularly.

IMPLICATIONS

Despite the availability of free online HIV resources and progress made in HIV management, significant opportunities for antiretroviral stewardship remain. Implementing electronic order entry updates, formulary upgrades, and formal pharmacy renal dose adjustments to optimize antiretroviral therapy will help clinicians harness these opportunities. Dedicated time and expertise for antiretroviral stewardship as part of local antimicrobial stewardship programs are needed.

ART-related medication errors in hospitalized people with HIV in the INSTI-era: analysis from 2 health systems in South Georgia, U.S

ABSTRACTART-related medication errors occur at high rates in hospitalized people with HIV (PWH), but few studies included modern regimens. As such, we evaluated ART-related medication errors in hospitalized PWH in an era where use of INSTI-based regimens dominate. This multi-center, retrospective cohort included PWH at least 18 years hospitalized in South Georgia, U.S. between March 2016 and March 2018. Of those eligible for inclusion, 400 were randomly selected and included. Three hundred sixty-three inpatient ART-related medication errors occurred in 203 patients during the study period due to incorrect scheduling (44%), an incorrect or incomplete regimen (27%), and drug-drug interactions (27%). Approximately 25% of errors persisted to discharge. Medication errors were more likely to occur in patients receiving NNRTI- or PI-containing multi-tablet regimens, whereas those receiving INSTI-containing multi-tablet regimens were less likely to experience a medication error. ART-related medication errors are less likely in patients receiving INSTI-containing multi-tablet regimens. Ensuring appropriate transition of ART throughout hospitalization remains an area in need of significant improvement.

Decreasing Prescribing Errors in Antimicrobial Stewardship Program-Restricted Medications

OBJECTIVES

Antimicrobial stewardship programs (ASPs) restrict prescribing practices to regulate antimicrobial use, increasing the risk of prescribing errors. This quality improvement project aimed to decrease the proportion of prescribing errors in ASP-restricted medications by standardizing workflow.

METHODS

The study took place on all inpatient units at a tertiary care children's hospital between January 2020 and February 2022. Patients <22 years old with an order for an ASP-restricted medication course were included. An interprofessional team used the Model for Improvement to design interventions targeted at reducing ASP-restricted medication prescribing errors. Plan-Do-Study-Act cycles included standardizing communication and medication review, implementing protocols, and developing electronic health record safety nets. The primary outcome was the proportion of ASP-restricted medication orders with a prescribing error. The secondary outcome was time between prescribing errors. Outcomes were plotted on control charts and analyzed for special cause variation. Outcomes were monitored for a 3-month sustainability period.

RESULTS

Nine-hundred ASP-restricted medication orders were included in the baseline period (January 2020-December 2020) and 1035 orders were included in the intervention period (January 2021-February 2022). The proportion of prescribing errors decreased from 10.9% to 4.6%, and special cause variation was observed in Feb 2021. Mean time between prescribing errors increased from 2.9 days to 8.5 days. These outcomes were sustained.

CONCLUSIONS

Quality improvement methods can be used to achieve a sustained reduction in the proportion of ASP-restricted medication orders with a prescribing error throughout an entire children's hospital.

Pharmacist-Involved Antiretroviral Stewardship Programs in People Living with HIV/AIDS: A Systematic Review

People living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS; PLWHA) frequently encounter antiretroviral (ARV) therapy-related problems. Clinical pharmacists with specialized training in ARV stewardship play an important role in managing these problems. However, there is a paucity of evidence to clarify the impact of clinical pharmacists' interventions on managing ARV therapy-related problems in PLWHA. Therefore, we aim to systematically review the literature to determine the nature and impact of pharmacists' interventions on managing medication-related problems in PLWHA. The review protocol was registered on International Prospective Register of Systematic Reviews (PROSPERO; CRD42020173078). Relevant records were identified from six electronic bibliographic databases (PubMed, Embase, EBSCOhost, ProQuest, Scopus, and the Cochrane Central Register) from their inception until September 2022. We included all randomized and nonrandomized interventional studies that were published in English. After the abstract and full-text screening, data were extracted from the selected studies, and the quality of the studies was assessed. The electronic database search and citation tracking identified two thousand and three citations. The review included 21 of these studies, involving 2998 PLWHA, published between 2014 and 2022. Pharmacists' interventions, working alone or in a multi-disciplinary team, comprised ARV medication review, management of adverse drug reactions (ADRs), therapeutic drug monitoring, prevention of drug interactions, and provision of drug information to PLWHA or the health care team. The pharmacist-involved interventions significantly reduced incorrect/incomplete ARV regimens, drug interactions, incorrect dosages, duplicate therapy, polypharmacy, administration errors, missing medication, wrong formulation, ADRs, and prescribing errors. Most studies reported that physicians usually accept more than 90% of the pharmacists' recommendations. ARV medication-related problems remain highly prevalent in PLWHA. Pharmacist-led interventions and stewardship significantly reduce ARV therapy-related problems in PLWHA and are widely accepted by physicians. Dedicated pharmacists with specialized training and credentialing in infectious diseases or HIV/AIDS have a great potential to improve health outcomes in PLWHA.

Interventions to reduce medication errors in adult medical and surgical settings: a systematic review

Background and Aims:

Medication errors occur at any point of the medication management process, and are a major cause of death and harm globally. The objective of this review was to compare the effectiveness of different interventions in reducing prescribing, dispensing and administration medication errors in acute medical and surgical settings.

Methods:

The protocol for this systematic review was registered in PROSPERO (CRD42019124587). The library databases, MEDLINE, CINAHL, EMBASE, PsycINFO, Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials were searched from inception to February 2019. Studies were included if they involved testing of an intervention aimed at reducing medication errors in adult, acute medical or surgical settings. Meta-analyses were performed to examine the effectiveness of intervention types.

Results:

A total of 34 articles were included with 12 intervention types identified. Meta-analysis showed that prescribing errors were reduced by pharmacist-led medication reconciliation, computerised medication reconciliation, pharmacist partnership, prescriber education, medication reconciliation by trained mentors and computerised physician order entry (CPOE) as single interventions. Medication administration errors were reduced by CPOE and the use of an automated drug distribution system as single interventions. Combined interventions were also found to be effective in reducing prescribing or administration medication errors. No interventions were found to reduce dispensing error rates. Most studies were conducted at single-site hospitals, with chart review being the most common method for collecting medication error data. Clinical significance of interventions was examined in 21 studies. Since many studies were conducted in a pre–post format, future studies should include a concurrent control group.

Conclusion:

The systematic review identified a number of single and combined intervention types that were effective in reducing medication errors, which clinicians and policymakers could consider for implementation in medical and surgical settings. New directions for future research should examine interdisciplinary collaborative approaches comprising physicians, pharmacists and nurses.

Lay summary

Activities to reduce medication errors in adult medical and surgical hospital areas

Introduction:

Medication errors or mistakes may happen at any time in hospital, and they are a major reason for death and harm around the world.

Objective:

To compare the effectiveness of different activities in reducing medication errors occurring with prescribing, giving and supplying medications in adult medical and surgical settings in hospital.

Methods:

Six library databases were examined from the time they were developed to February 2019. Studies were included if they involved testing of an activity aimed at reducing medication errors in adult medical and surgical settings in hospital. Statistical analysis was used to look at the success of different types of activities.

Results:

A total of 34 studies were included with 12 activity types identified. Statistical analysis showed that prescribing errors were reduced by pharmacists matching medications, computers matching medications, partnerships with pharmacists, prescriber education, medication matching by trained physicians, and computerised physician order entry (CPOE). Medication-giving errors were reduced by the use of CPOE and an automated medication distribution system. The combination of different activity types were also shown to be successful in reducing prescribing or medication-giving errors. No activities were found to be successful in reducing errors relating to supplying medications. Most studies were conducted at one hospital with reviewing patient charts being the most common way for collecting information about medication errors. In 21 out of 34 articles, researchers examined the effect of activity types on patient harm caused by medication errors. Many studies did not involve the use of a control group that does not receive the activity.

Conclusion:

A number of activity types were shown to be successful in reducing prescribing and medication-giving errors. New directions for future research should examine activities comprising health professionals working together.

Impact of Pharmacist-Driven Antiretroviral Stewardship and Transitions of Care Interventions on Persons With Human Immunodeficiency Virus

Background

Persons with human immunodeficiency virus (HIV) experience high rates of medication-related errors when admitted to the inpatient setting. Data are lacking on the impact of a combined antiretroviral (ARV) stewardship and transitions of care (TOC) program. We investigated the impact of a pharmacist-driven ARV stewardship and TOC program in persons with HIV.

Methods

This was a retrospective, quasi-experimental analysis evaluating the impact of an HIV-trained clinical pharmacist on hospitalized persons with HIV. Patients included in the study were adults following up, or planning to follow up, at the University of Illinois (UI) outpatient clinics for HIV care and admitted to the University of Illinois Hospital. Data were collected between July 1, 2017 and December 31, 2017 for the preimplementation phase and between July 1, 2018 and December 31, 2018 for the postimplementation phase. Primary and secondary endpoints included medication error rates related to antiretroviral therapy (ART) and opportunistic infection (OI) medications, all-cause readmission rates, medication access at time of hospital discharge, and linkage to care rates.

Results

A total of 128 patients were included in the study: 60 in the preimplementation phase and 68 in the postimplementation phase. After the implementation of this program, medication error rates associated with ART and OI medications decreased from 17% (10 of 60) to 6% (4 of 68) (P = .051), 30-day all-cause readmission rates decreased significantly from 27% (16 of 60) to 12% (8 of 68) (P = .03), and linkage to care rates increased significantly from 78% (46 of 59) to 92% (61 of 66) (P = .02).

Conclusions

A pharmacist-led ARV stewardship and TOC program improved overall care of persons with HIV through reduction in medication error rates, all-cause readmission rates, and an improvement in linkage to care rates.

A Call to Action: The Role of Antiretroviral Stewardship in Inpatient Practice, a Joint Policy Paper of the Infectious Diseases Society of America, HIV Medicine Association, and American Academy of HIV Medicine

Persons living with human immunodeficiency virus (HIV) and others receiving antiretrovirals are at risk for medication errors during hospitalization and at transitions of care. These errors may result in adverse effects or viral resistance, limiting future treatment options. A range of interventions is described in the literature to decrease the occurrence or duration of medication errors, including review of electronic health records, clinical checklists at care transitions, and daily review of medication lists. To reduce the risk of medication-related errors, antiretroviral stewardship programs (ARVSPs) are needed to enhance patient safety. This call to action, endorsed by the Infectious Diseases Society of America, the HIV Medicine Association, and the American Academy of HIV Medicine, is modeled upon the success of antimicrobial stewardship programs now mandated by the Joint Commission. Herein, we propose definitions of ARVSPs, suggest resources for ARVSP leadership, and provide a summary of published, successful strategies for ARVSP that healthcare facilities may use to develop locally appropriate programs.

Antiretroviral Stewardship: A Review of Published Outcomes with Recommendations for Program Implementation

Persons living with HIV (PLWHs) are at high risk for medication errors when hospitalized, but antiretroviral medications are not often evaluated by antimicrobial stewardship programs (ASPs) because they are not specifically discussed in the standards of practice. However, antiretroviral (ARV) stewardship programs (ARVSPs) have been shown to decrease medication error rates and improve other outcomes. The goal of this article is to review published literature on ARVSPs and provide guidance on key aspects of ARVSPs. A MEDLINE search using the term "antiretroviral stewardship" was conducted. Original research articles evaluating ARVSPs in hospitalized, adult PLWHs were included. Six original research articles evaluating unique inpatient ARVSPs met inclusion criteria. All 6 studies evaluating medication errors as the primary outcome found a significant reduction in errors in the postimplementation phase. Based on current standards for ASPs, we propose core elements for ARVSPs. Future organizational guidelines for antimicrobial stewardship should include official recommendations for ARV medications.

An Evaluation of Pharmacist-Led Interventions for Inpatient HIV-Related Medication Errors

Background: Inpatient HIV-related medication errors occur in up to 86% of patients. Objective: To evaluate the number of antiretroviral therapy (ART)- and opportunistic infection (OI)-related medication errors following the implementation of pharmacist-directed interventions. Methods: This quasi-experiment assessed adult patients with HIV who received ART, OI prophylaxis, or both from December 1, 2014, to February 28, 2017 (pre-intervention) or December 1, 2017, to February 28, 2018 (post-intervention). Pre-intervention patients were assessed retrospectively; verbal and written education were provided (intervention); prospective audit and feedback was conducted for post-intervention patients. The primary outcome was rate of ART errors between groups. Secondary outcomes included rate of OI errors, time to resolution of ART and OI errors, types of errors, and rate of recommendation acceptance. Results: Sixty-seven patients were included in each group. ART errors occurred in 44.8% and 32.8% (P = .156), respectively. OI prophylaxis errors occurred in 11.9% versus 9% (P = .572), respectively. Medication omission decreased significantly in the post-intervention group (31.3% vs 11.9%; P = .006). Pharmacist-based interventions increased in the post-intervention group (6.3% vs 52.9%; P = .001). No statistical difference was found in time to error resolution (72 vs 48 hours; P = .123), but errors resolved during admission significantly increased (50% vs 86.8%; P < .001). No difference was found in rate of intervention acceptance (100% vs 97%). Conclusion and Relevance: ART and OI prophylaxis errors resolved a day faster in the pharmacist-led, post-intervention period, and there was a trend toward error reduction. Future interventions should target prescribing errors on admission using follow-up education and evaluation of medication reconciliation practices in HIV-infected patients.

Impact of an Antiretroviral Stewardship Team on the Care of Patients With Human Immunodeficiency Virus Infection Admitted to an Academic Medical Center

BACKGROUND

Interdisciplinary antiretroviral stewardship teams, comprising a human immunodeficiency virus pharmacist specialist, an infectious diseases physician, and associated learners, have the ability to assist in identification and correction of inpatient antiretroviral-related errors.

METHODS

Electronic medical records of patients with antiretroviral orders admitted to our hospital were evaluated for the number of interventions made by the stewardship team, number of admissions with errors identified, risk factors for occurrence of errors, and cost savings. Risk factors were analyzed by means of multivariable logistic regression. Cost savings were estimated by the documentation system Clinical Measures.

RESULTS

A total of 567 admissions were included for analysis in a 1-year study period. Forty-three percent of admissions (245 of 567) had ≥1 intervention, with 336 interventions in total. The following were identified as risk factors for error: multitablet inpatient regimen (odds ratio, 1.834; 95% confidence interval, 1.160-2.899; P = .009), admission to the intensive care unit (2.803; 1.280-6.136; P = .01), care provided by a surgery service (1.762; 1.082-2.868; P = .02), increased number of days reviewed (1.061; 1.008-1.117; P = .02), and noninstitutional outpatient provider (1.375; .972-1.946; P = .07). The 1-year cost savings were estimated to be $263 428.

CONCLUSIONS

Antiretroviral stewardship teams optimize patient care through identification and correction of antiretroviral-related errors. Errors may be more common in patients with multitablet inpatient regimens, admission to the intensive care unit, care provided by a surgery service, and increased number of hospital days reviewed. Once antiretroviral-related errors are identified, the ability to correct them provides cost savings.

Reducing medication errors involving antiretroviral therapy with targeted electronic medical record modifications

Medication errors are common among HIV-infected patients on anti-retroviral therapy (ART), especially when transitioning to the inpatient setting. In previous studies, medication error rates among hospitalized patients on ART have been reported to exceed 50%. When patients receiving ART are admitted to the hospital, medication errors can be prevented through optimization of administration instructions and dosing defaults in order-entry screens in the electronic medical record (EMR). We sought to evaluate the impact of EMR modifications (defaulted doses, frequencies, and administration instructions) implemented to improve the order-entry process and reduce errors. All adult patients admitted between 10/1/2010-3/31/2012 (pre-EMR modification) and 10/1/2013-3/31/2014 (post-EMR modification) that continued on ART upon admission were included. The primary outcome was the overall rate of medication errors identified through review by the antimicrobial stewardship program (ASP). We also characterized the types of medication errors identified during the two time periods. Following EMR modifications, the medication error rate identified through ASP review was reduced from 50.2% to 28.2% (P < 0.01). The number of medication related errors relating to dosage (regimens requiring dose optimization, renal dose adjustment, and dose timing) were reduced by 22% (P < 0.01). Modifications at the anti-retroviral medication order-entry screens in the EMR significantly reduced medication errors, particularly with respect to dosing and dose timing.

All aboard!: Involvement of medical and pharmacy trainees in antimicrobial stewardship

Antimicrobial stewardship (AS) involves the appropriate selection of antimicrobials. Antimicrobial stewardship programs are mandated in hospitals and are expanding to involve outpatient arenas. Multiple articles have been published describing the need for AS education for medical and pharmacy students, beginning early in the students’ career to develop into competent AS practitioners. Additionally, publications have described the role and impact of medical and pharmacy trainees on AS programs. Here, we review the published evidence describing medical and pharmacy trainees’ involvement in AS and call for future research in this area.

To Assess the Success of Computerized Order Sets and Pharmacy Education Modules in Improving Antiretroviral Prescribing

PURPOSE

To assess the success of order set and pharmacist training improvement (OSPTI) in improving prescription of antiretroviral therapy (ART) in a tertiary care, public, teaching hospital.

METHODS

In this pre-OSPTI (January 2012 through June 2013) and post-OSPTI study (July 2013 through September 2014), an infectious disease pharmacist reviewed all patients on ART. A review of intervention data in July 2013 led to order-set changes in the hospital's computerized order entry system for frequently intervened on antiretrovirals: ritonavir, tenofovir, emtricitabine/tenofovir disoproxil fumarate (FTC/TDF), and lamivudine. Concurrently, case-based education modules were conducted to help pharmacists identify ART errors. The number of patients on ART, number of interventions, and types of ritonavir interventions were compared between pre- and post-OSPTI periods.

RESULTS

In the pre-OSPTI period, an average of 239 patients were reviewed per quarter compared to an average of 216 per quarter in the post-OSPTI period. After implementing enhanced order sets, the number of interventions decreased by approximately 34% ( P < .0001). The number of ritonavir interventions decreased on average by 45% ( P < .0001), although the types of ritonavir interventions were similar.

CONCLUSION

Enhanced antiretroviral order sets and pharmacy education modules improved ART prescription by reducing the overall number of antiretroviral interventions required per quarter. This modality was effective in improving prescribing of ART and reducing the need for pharmacist interventions.

Antiretroviral Stewardship in a Pediatric HIV Clinic: Development, Implementation and Improved Clinical Outcomes

BACKGROUND

Antiretroviral (ARV) management in pediatrics is a challenging process in which multiple barriers to optimal therapy can lead to poor clinical outcomes. In a pediatric HIV clinic, we implemented a systematic ARV stewardship program to evaluate ARV regimens and make recommendations for optimization when indicated.

METHODS

A comprehensive assessment tool was used to screen for issues related to genotypic resistance, virologic/immunologic response, drug-drug interactions, side effects and potential for regimen simplification. The ARV stewardship team (AST) made recommendations to the HIV clinic provider, and followed patients prospectively to assess clinical outcomes at 6 and 12 months.

RESULTS

The most common interventions made by the AST included regimen optimization in patients on suboptimal regimens based on resistance mutations (35.4%), switching to safer ARVs (33.3%) and averting significant drug-drug interactions (10.4%). In patients anticipated to have a change in viral load (VL) as a result of the AST recommendations, we identified a significant benefit in virologic outcomes at 6 and 12 months when recommendations were implemented within 6 months of ARV review. Patients who had recommendations implemented within 6 months had a 7-fold higher probability of achieving a 0.7 log10 reduction in VL by 6 months, and this benefit remained significant after controlling for adherence [adjusted odds ratio: 6.8 (95% confidence interval: 1.03-44.9; P <0.05)].

CONCLUSIONS

A systematic ARV stewardship program implemented at a pediatric HIV clinic significantly improved clinical outcomes. ARV stewardship programs can be considered a core strategy for continuous quality improvement in the management of HIV-infected children and adolescents.

Impact of Stewardship Interventions on Antiretroviral Medication Errors in an Urban Medical Center: A 3-Year, Multiphase Study

BACKGROUND

There is a high prevalence of HIV infection in Newark, New Jersey, with University Hospital admitting approximately 600 HIV-infected patients per year. Medication errors involving antiretroviral therapy (ART) could significantly affect treatment outcomes. The goal of this study was to evaluate the effectiveness of various stewardship interventions in reducing the prevalence of prescribing errors involving ART.

METHODS

This was a retrospective review of all inpatients receiving ART for HIV treatment during three distinct 6-month intervals over a 3-year period. During the first year, the baseline prevalence of medication errors was determined. During the second year, physician and pharmacist education was provided, and a computerized order entry system with drug information resources and prescribing recommendations was implemented. Prospective audit of ART orders with feedback was conducted in the third year. Analyses and comparisons were made across the three phases of this study.

RESULTS

Of the 334 patients with HIV admitted in the first year, 45% had at least one antiretroviral medication error and 38% had uncorrected errors at the time of discharge. After education and computerized order entry, significant reductions in medication error rates were observed compared to baseline rates; 36% of 315 admissions had at least one error and 31% had uncorrected errors at discharge. While the prevalence of antiretroviral errors in year 3 was similar to that of year 2 (37% of 276 admissions), there was a significant decrease in the prevalence of uncorrected errors at discharge (12%) with the use of prospective review and intervention.

CONCLUSIONS

Interventions, such as education and guideline development, can aid in reducing ART medication errors, but a committed stewardship program is necessary to elicit the greatest impact.

Evaluation of the occurrence and type of antiretroviral and opportunistic infection medication errors within the inpatient setting

Background:

Previous data reports inpatient antiretroviral (ARV) and opportunistic infection (OI) medication errors in as many as 86% of patients, with averages ranging from 1.16-2.7 errors/patient.

Objective:

To determine the occurrence and type of inpatient ARV and OI medication errors at our institution.

Methods:

A retrospective, observational, electronic medical chart review of patients with HIV/AIDS admitted between February 15, 2011- May 22, 2012 was conducted to assess the occurrence and type of ARV and OI medication errors. Secondary outcomes included assessing each medication with an error and evaluating its potential for a medication error, calculating a medication error rate per patient, evaluating whether a non-formulary (NF) medication impacted the error potential, determining whether a clinical pharmacist on service decreased the medication error rate, and assessing whether patients who experienced an error were more likely to have a longer length of stay (LOS). Analysis included descriptive statistics, averages, and Spearmen rank correlation.

Results:

There were 344 patients included in this analysis, 132 (38%) experienced 190 medication errors (1.44 errors/patient). An omitted order was the most frequent ARV error and accounted for 30% (n=57) of total errors. There were 166 patients requiring OI medications, 37 patients experienced 39 medication errors. Omitting OI prophylaxis accounted for 31 errors. Only 45 of 190 (24%) errors were corrected prior to discharge. Being prescribed at least 1 NF medication was correlated with increased errors (n=193 patients “on NF medication”, p<0.025, r=0.12). Coverage of a service by a clinical pharmacist did not affect the number of errors. Patients experiencing an error had a longer LOS (p=0.02).

Conclusions:

Errors relating to ARV and OI medications are frequent in HIV-infected inpatients. More errors occurred in patients receiving NF medications. Suggested interventions include formulary revision, education, and training. Dedicated HIV clinicians with adequate training and credentialing may improve the management of this specialized disease state.
