Prescribing pharmacists in the ambulatory care setting: Experience at the University of North Carolina Medical Center

PURPOSE

The prescribing authorities, clinical activities, and productivity documentation strategies of ambulatory care clinic-based pharmacists practicing within a large academic health system are described.

SUMMARY

North Carolina law encourages progressive pharmacy practice through acquisition of the clinical pharmacist practitioner (CPP) designation. Qualified CPPs are authorized to provide collaborative drug therapy management services, including medication prescribing and ordering of laboratory tests, according to defined protocols and under physician supervision. The University of North Carolina Medical Center has approximately 30 CPPs deployed across a wide range of ambulatory care clinical practice sites. This article describes (1) the pharmacy department's implementation of an ambulatory care practice model, (2) the credentialing and privileging process leading to granting of prescribing privileges, (3) metrics used to demonstrate the impact of CPP activities, (4) recommended general criteria for ambulatory care practice site identification, and (5) strategies for overcoming barriers to successful implementation of ambulatory care-focused clinical pharmacist services. Aggregated intervention-tracking data compiled by seven of the medical center's CPP ambulatory care practice sites indicate extensive CPP involvement in direct patient care encounters and patient or provider consultations, with large numbers of medication-related interventions to support institutional cost-avoidance and revenue goals.

CONCLUSION

CPPs deployed at the medical center's ambulatory care clinics have had a positive impact on clinical and cost outcomes, improving patient care through interventions, contributing to readmission reduction efforts, generating indirect revenue through cost avoidance, and generating new revenue through billing for patient visits.

Identification of risk factors for inappropriate and suboptimal initiation of direct oral anticoagulants

Direct Oral Anticoagulants (DOACs) require specific dosing and monitoring to ensure safe and appropriate use. The purpose of this evaluation was to identify patient- and process-related factors that correlate with increased risk of inappropriate prescribing of DOACs. A retrospective chart review was conducted in three outpatient clinics within an academic medical center to identify patients started on DOAC therapy and evaluate the appropriateness of DOAC initiation. Data collected included patient demographics, DOAC medication initiated, dose, indication, baseline laboratory values, concomitant medications, type and specialty of prescriber, and initiation setting. Appropriateness of initial dose was assessed and data were analyzed in order to identify factors correlating with inappropriate use. One-hundred sixty-seven patients initiated on a DOAC were identified. Most patients were prescribed anticoagulation for atrial fibrillation (74.9 %) and most commonly prescribed rivaroxaban (62.9 %). An inappropriate dose was prescribed in 24 (14.4 %) patients. Female patients and patients over 75 years were more likely to be prescribed an inappropriate initial dose. Baseline evaluation of blood counts and organ function were often not performed: hemoglobin values had not been drawn within the month prior to initiation in 28.7 % of patients, serum creatinine in 22.8 %, alanine transaminase in 52.1 %, and total bilirubin in 64.1 %. Lack of baseline labs was more pronounced in patients initiated on a DOAC in the outpatient setting. Dosing and baseline lab collection for DOAC initiation were suboptimal in all settings analyzed. Targeted interventions are needed to ensure the safe and appropriate use of DOAC therapy.

Design of a medication therapy management program for Medicare beneficiaries: qualitative findings from patients and physicians

BACKGROUND

The quality of pharmacologic care provided to older adults is less than optimal. Medication therapy management (MTM) programs delivered to older adults in the ambulatory care setting may improve the quality of medication use for these individuals.

OBJECTIVES

We conducted focus groups with older adults and primary care physicians to explore (1) older adults' experiences working with a clinical pharmacist in managing medications, (2) physician perspectives on the role of clinical pharmacists in facilitating medication management, and (3) key attributes of an effective MTM program and potential barriers from patient and provider perspectives.

METHODS

Five focus groups (4 with older adults, 1 with physicians) were conducted by a trained moderator using a semistructured interview guide. Each participant completed a demographic questionnaire. Sessions were recorded, transcribed verbatim, and analyzed using qualitative analysis software for theme identification.

RESULTS

Twenty-eight older adults and 8 physicians participated. Older adults valued the professional, trusting nature of their interactions with the pharmacist. They found the clinical pharmacist to be a useful resource, thorough, personable, and a valuable team member. Physicians believe that the clinical pharmacist fills a unique role as a specialized practitioner, contributing meaningfully to patient care. Physicians emphasized the importance of effective communication, pharmacist access to the medical record, and a mutually trusting relationship as key attributes of a program. Potential barriers to an effective program include poor communication and lack of familiarity with the patient's history. The lack of a sustainable reimbursement model was cited as a barrier to widespread implementation of MTM.

CONCLUSIONS

This study provides information to assist pharmacists in designing MTM programs in the ambulatory setting. Key attributes of an effective program include being comprehensive and addressing all medication-related needs over time. The clinical pharmacist's ability to build trusting relationships with patients and providers is essential.

Development and testing of a tool for assessing and resolving medication-related problems in older adults in an ambulatory care setting: the individualized medication assessment and planning (iMAP) tool

BACKGROUND

Medication is one of the most important interventions for improving the health of older adults, yet it has great potential for causing harm. Clinical pharmacists are well positioned to engage in medication assessment and planning. The Individualized Medication Assessment and Planning (iMAP) tool was developed to aid clinical pharmacists in documenting medication-related problems (MRPs) and associated recommendations.

OBJECTIVE

The purpose of our study was to assess the reliability and usability of the iMAP tool in classifying MRPs and associated recommendations in older adults in the ambulatory care setting.

METHODS

Three cases, representative of older adults seen in an outpatient setting, were developed. Pilot testing was conducted and a "gold standard" key developed. Eight eligible pharmacists consented to participate in the study. They were instructed to read each case, make an assessment of MRPs, formulate a plan, and document the information using the iMAP tool. Inter-rater reliability was assessed for each case, comparing the pharmacists' identified MRPs and recommendations to the gold standard. Consistency of categorization across reviewers was assessed using the κ statistic or percent agreement.

RESULTS

The mean κ across the 8 pharmacists in classifying MRPs compared with the gold standard was 0.74 (range, 0.54-1.00) for case 1 and 0.68 (range, 0.36-1.00) for case 2, indicating substantial agreement. For case 3, percent agreement was 63% (range, 40%-100%). The mean κ across the 8 pharmacists when classifying recommendations compared with the gold standard was 0.87 (range, 0.58-1.00) for case 1 and 0.88 (range, 0.75-1.00) for case 2, indicating almost perfect agreement. For case 3, percent agreement was 68% (range, 40%-100%). Clinical pharmacists found the iMAP tool easy to use.

CONCLUSIONS

The iMAP tool provides a reliable and standardized approach for clinical pharmacists to use in the ambulatory care setting to classify MRPs and associated recommendations. Future studies will explore the predictive validity of the tool on clinical outcomes such as health care utilization.
