Implementation of a medication therapy management collaborative within a pediatric health system

A coordinated approach for managing polypharmacy among children with medical complexity: rationale and design of the Pediatric Medication Therapy Management (pMTM) randomized controlled trial

BACKGROUND

Children with medical complexity (CMC) often rely upon the use of multiple medications to sustain quality of life and control substantial symptom burden. Pediatric polypharmacy (≥ 5 concurrent medications) is prevalent and increases the risk of medication-related problems (MRPs). Although MRPs are associated with pediatric morbidity and healthcare utilization, polypharmacy is infrequently assessed during routine clinical care for CMC. The aim of this randomized controlled trial is to determine if a structured pharmacist-led Pediatric Medication Therapy Management (pMTM) intervention reduces MRP counts, as well as the secondary outcomes of symptom burden and acute healthcare utilization.

METHODS

This is a hybrid type 2 randomized controlled trial assessing the effectiveness of pMTM compared to usual care in a large, patient-centered medical home for CMC. Eligible patients include all children ages 2-18 years old, with ≥ 1 complex chronic condition, and with ≥ 5 active medications, as well as their English-speaking primary caregivers. Child participants and their primary parental caregivers will be randomized to pMTM or usual care before a non-acute primary care visit and followed for 90 days. Using generalized linear models, the overall effectiveness of the intervention will be evaluated using total MRP counts at 90 days following pMTM intervention or usual care visit. Following attrition, a total of 296 CMC will contribute measurements at 90 days, which provides > 90% power to detect a clinically significant 1.0 reduction in total MRPs with an alpha level of 0.05. Secondary outcomes include Parent-Reported Outcomes of Symptoms (PRO-Sx) symptom burden scores and acute healthcare visit counts. Program replication costs will be assessed using time-driven activity-based scoring.

DISCUSSION

This pMTM trial aims to test hypotheses that a patient-centered medication optimization intervention delivered by pediatric pharmacists will result in lower MRP counts, stable or improved symptom burdens, and fewer cumulative acute healthcare encounters at 90 days following pMTM compared to usual care. The results of this trial will be used to quantify medication-related outcomes, safety, and value for a high-utilization group of CMC, and outcomes may elucidate the role of integrated pharmacist services as a key component of outpatient complex care programs for this priority pediatric population.

TRIAL REGISTRATION

This trial was prospectively registered at clinicaltrials.gov (NCT05761847) on Feb 25, 2023.

Identifying opportunities for pediatric medication therapy management in children with medical complexity

BACKGROUND

Despite potential benefits of medication therapy management (MTM) for complex pediatric patients, implementation of pediatric MTM services is rare.

OBJECTIVES

To describe how a standardized pediatric MTM model identifies potential interventions and their impact on medication regimen complexity index (MRCI) scores in children with medical complexity (CMC) and polypharmacy.

METHODS

This retrospective proof-of-concept study included pediatric patients receiving primary care in a large outpatient primary care medical home for CMC within a tertiary freestanding children's hospital from August 2020 to July 2021. Medication profiles of established patients aged 0-18 years with at least 5 active medications at the time of the index visit were assessed for medication-related concerns, potential interventions, and potential impact of proposed interventions on MRCI scores.

RESULTS

Among 100 patients, an average of 3.4 ± 2.6 medication-related concerns was identified using the pediatric MTM model. Common medication-related concerns (>25% of patients) included inappropriate or unnecessary therapy, suboptimal therapy, undertreated symptom, adverse effect, clinically impactful drug-drug interaction, or duplication of therapy. A total of 97% had opportunities for 5.0 ± 2.9 potential interventions. Most common proposed interventions included drug discontinuation trial (69%), patient or caregiver education (55%), dosage form modification (51%), dose modification (49%), and frequency modification (46%). The mean baseline MRCI score was 32.6 (95% CI 29.3-35.8) among all patients. MRCI scores decreased by a mean of 4.9 (95% CI 3.8-5.9) after application of the theoretical interventions (P < 0.001). Mean potential score reduction was not significantly affected by patient age or number of complex chronic conditions. Potential impact of the proposed interventions on MRCI score was significantly greater in patients with higher baseline medication counts (P < 0.001).

CONCLUSION

Most CMC would likely benefit from a pharmacist-guided pediatric MTM service. A standardized review of active medication regimens identified multiple medication-related concerns and potential interventions for nearly all patients. Proposed medication interventions would significantly reduce medication regimen complexity as measured by MRCI. Further prospective evaluation of a pharmacist-guided pediatric MTM service is warranted.

Incorporating medication therapy management into community pharmacy workflows

Medication Therapy Management (MTM) is a group of pharmacist-provided services that optimize individual patients' drug therapy outcomes. Since community pharmacies' primary business platform is the dispensing of medications, and providing MTM services is a secondary source of revenue, pharmacies with limited resources are operationally challenged when trying to efficiently deliver both types of services. To address this problem, we follow a queueing network approach to develop an operational model of a community pharmacy workflow. Through our model, we derive structural results to determine conditions for a pharmacy to achieve economies of scope when providing both prescription and MTM services. We also develop a process simulation to compare different scenarios according to our economies of scope model, varying in provided services, personnel, service demand, and other operational variables. Outcomes examined include profitability, service rate, and sensitivity of some operation variables to profitability. Based on our results, we provide practical insights to help community pharmacy administrators and healthcare policy makers in their decision process.

Access to clinical pharmacy services in a pharmacist-physician covisit model

BACKGROUND

A pharmacist-physician covisit model in which patients see both a pharmacist and physician on the same day was established in a primary care practice. Previously, patients were seen in a referrals-based model in which providers referred patients for clinical pharmacy services on a different day.

OBJECTIVE

To assess access to clinical pharmacy services in a pharmacist-physician covisit model compared to a referrals-based model.

METHODS

A retrospective chart review was completed for patients who were seen by physicians on pre-specified half-days of clinic before and after implementation of the covisit model. Covisit model half-days between June 29, 2018 and September 30, 2018 and matched half-days from 2015 were included. Charts were reviewed to determine if patients scheduled to see the physician would benefit from clinical pharmacy services, including being seen for chronic disease management, eligible for a Medicare Annual Wellness Visit (AWV), prescribed medications that required counseling, had an adverse medication-related event, or had adherence concerns. Those eligible for clinical pharmacy services were further reviewed to determine if the patient interacted with a pharmacist within three months of their visit.

RESULTS

Prior to implementation of the covisit model, 123 patient visits were completed on the pre-specified half-days. Of these, 61 patients (49.6%) were deemed eligible for clinical pharmacy services. In the covisit model, 149 patients were seen by the physician, of which 69 patients (46%) were eligible for clinical pharmacy services. More patients in the covisit cohort went on to interact with a pharmacist (56 patients, 81% vs. 10 patients, 16%, adjusted OR = 32.98, 95% CI [8.89-122.39]). The most common reasons patients were identified for clinical pharmacy services were eligibility for AWV, hypertension, and diabetes.

CONCLUSIONS

A pharmacist-physician covisit model significantly increased accessibility to clinical pharmacy services compared to a referrals-based model.

The clinical impact of pharmacist services on mental health collaborative teams: A systematic review

OBJECTIVE

To evaluate the clinical impact of mental health collaborative teams that include pharmacists.

DATA SOURCES

PubMed, PsychInfo, Clinialtrials.gov, International Pharmaceutical Abstracts.

STUDY SELECTIONS

Studies in which pharmacists were part of a mental health collaborative team (defined as 2 or more health care providers working together to provide enhanced mental health care services to patients), mental health clinical outcomes were measured with a validated tool, and the articles were written in English were included. Articles were searched from database inception to July 2019 and were excluded if a quantifiable comparison of mental health clinical outcomes was not included or collaboration was not described.

DATA EXTRACTION

Two authors independently screened titles and abstracts for relevance. Full-text articles that potentially met inclusion criteria were retrieved, read, and evaluated for inclusion using the eligibility criteria.

RESULTS

All 9 included studies reported improvements in mental health clinical outcomes when using collaborative teams that included pharmacists. Depression (n = 8) and post-traumatic stress disorder (PTSD) (n = 1) were the mental health conditions included in the studies. Overall, 5 of 7 of the randomized controlled trials (RCTs) had statistically significant improvement in mental health clinical outcomes between the intervention groups, which included the collaborative teams and a "usual care" groups, which did not. Four of the 5 studies were set in Veterans Affairs (VA) clinics. The 2 non-RCT pre-post studies showed improvements in clinical outcomes but did not achieve statistical significance.

CONCLUSION

Evidence shows that collaborative teams that include pharmacists are effective at improving mental health outcomes in patients with depression and PTSD. Future studies should include non-VA settings and other mental health conditions to understand pharmacists' impact more broadly in mental health collaborative teams. Clarifying and understanding the overlapping roles and responsibilities of members of the team may be the next step to continue improving mental health clinical outcomes.

Creating a Pharmacotherapy Collaborative Practice Network to Manage Medications for Children and Youth: A Population Health Perspective

Children with special health care needs (CSHCN) use relatively high quantities of healthcare resources and have overall higher morbidity than the general pediatric population. Embedding clinical pharmacists into the Patient-Centered Medical Home (PCMH) to provide comprehensive medication management (CMM) through collaborative practice agreements (CPAs) for children, especially for CSHCN, can improve outcomes, enhance the experience of care for families, and reduce the cost of care. Potential network infrastructures for collaborative practice focused on CSHCN populations, common language and terminology for CMM, and clinical pharmacist workforce estimates are provided. Applying the results from the CMM in Primary Care grant, this paper outlines the following: (1) setting up collaborative practices for CMM between clinical pharmacists and pediatricians (primary care pediatricians and sub-specialties, such as pediatric clinical pharmacology); (2) proposing various models, organizational structures, design requirements, and shared electronic health record (EHR) needs; and (3) outlining consistent documentation of CMM by clinical pharmacists in CSHCN populations.

Standardized documentation workflow within an electronic health record to track pharmacists' interventions in pediatric ambulatory care clinics

OBJECTIVES

To describe the implementation of a standardized documentation workflow within an electronic health record (EHR) and to track pharmacists' interventions in pediatric ambulatory care clinics.

SETTING

Ambulatory care clinics and a transitions-of-care (TOC) service within a pediatric health care system in central Ohio.

PRACTICE DESCRIPTION

Ambulatory clinical pharmacists work as integrated members of the health care team in 7 pediatric ambulatory care clinics and a TOC service to achieve the best medication-related outcomes for patients.

PRACTICE INNOVATION

A standardized documentation workflow was established among ambulatory clinical pharmacists to document the interventions made in their practice settings with the use of a tool in the EHR. A weekly report from the EHR was run by a technician to gather intervention data, identify reimbursable opportunities, and document and bill via a separate Internet-based medication therapy management platform.

EVALUATION

The success of the new documentation workflow was evaluated, and continuous feedback was gathered from the pharmacists and the billing technician. Updates were provided to the ambulatory clinical pharmacist at monthly staff meetings and workflow changes implemented as needed.

RESULTS

A total of 5210 interventions were documented by the pharmacists in various intervention categories. The 3 most common intervention categories included patient and medication education (1765), medication reconciliations (1170), and compliance assessments (795).

CONCLUSION

A standardized documentation workflow allowed for consistent tracking of interventions across ambulatory care clinics and a TOC service. Key elements to the successful implementation of this new documentation workflow included proper training and continuous feedback to the ambulatory clinical pharmacists, assistance from a billing technician, and consistent documentation by the ambulatory clinical pharmacists.
