Using a pharmacist-community health worker collaboration to address medication adherence barriers

The impact of interprofessional collaboration between pharmacists and community health workers on medication adherence: a systematic review

BACKGROUND

There is increasing evidence to support the effectiveness of interventions involving community health workers (CHWs) in improving patient health outcomes, which reinforces their growing integration in healthcare teams. However, little is known about the interprofessional collaboration between pharmacists and CHWs. This systematic review aimed to explore the impact of interprofessional interventions involving pharmacists and CHWs on patient medication adherence.

METHODS

The English language scientific literature published in Embase, MEDLINE, Web of Science, CINAHL, Scopus, plus the grey literature were searched in October 2024. Using the software Covidence, two authors screened article titles and abstracts and assessed full-text articles for eligibility. Studies were included if (i) the intervention was delivered by pharmacists and CHWs and (ii) reported on medication adherence outcomes. Data were extracted using a customized template using Excel and synthetized narratively. The Effective Public Health Practice Project quality assessment tool was used to assess the studies' methodological quality.

RESULTS

Eight studies met the inclusion criteria, including a total of 1577 participants. Seven studies were conducted in the United States, and six were published since 2020. The interventions consisted of medication therapy management, medication reconciliation, and repeated education sessions. The CHW shared clinical and non-clinical patient information and ensured a culturally safe environment while the pharmacist delivered the clinical intervention. In five studies, medication adherence was evaluated solely through patient self-reported measures. One study used an objective measure (i.e., pharmacy refill records) to evaluate medication adherence. Only two studies assessed medication adherence using both self-reported and objective measures (i.e., pill count and proportion of days covered). A significant improvement in medication adherence was observed in three of the eight studies. Half of the studies were of weak quality and half of moderate quality.

CONCLUSIONS

There was a small number of studies identified which focused on the impact of interprofessional collaboration between pharmacists and CHWs on medication adherence. The impact of the interprofessional interventions on medication adherence was limited. Further studies of higher quality are needed to better evaluate the impact of such collaboration on patient health outcomes.

Interprofessional collaboration between pharmacists and community health workers: a scoping review

INTRODUCTION

Community health workers (CHWs) help bridge the cultural gap between health services and the communities they serve. CHWs work with physicians, nurses and social workers, but little is known about their collaboration with pharmacists. This scoping review aims to describe the interprofessional collaboration between CHWs and pharmacists, the types of interventions they deliver and CHWs' and pharmacists' specific roles within these interventions.

METHOD

The scientific literature published in PubMed, Embase, MEDLINE, Scopus, Web of Science, PsycInfo, CINAHL and the grey literature were searched. Inclusion criteria were that the research (i) involved pharmacists and CHWs working collaboratively and (ii) included an intervention, service or program. One researcher screened all articles, and two reviewers screened 6% of articles (20/340) assessed for eligibility, using the software Covidence. After the discrepancies were resolved, data from the included articles were extracted using a customized template for data extraction and synthesized narratively.

RESULTS

Eighteen studies met the inclusion criteria. Most were conducted in the USA (14/18) and were published since 2020 (12/18). Most interventions involved medication reviews, support for medication adherence, disease prevention or addressing the social determinants of health. Pharmacists had primarily clinical roles (i.e., medication reconciliation and patient education), while the CHWs' roles consisted of collecting patient information, supporting patient self-management, bridging the cultural gap by translating information in the patient's language and ensuring patient follow-up. The collaborative practice occurred via interprofessional referral, ranging from the CHW facilitating the link between the patient and the pharmacist, and information sharing between the CHW and the pharmacist, to an interprofessional collaborative practice where CHWs and pharmacists delivered the intervention together.

CONCLUSION

While CHWs and pharmacists had independent roles as part of the interventions, they also collaborated at various levels to deliver services to patients. CHWs have an important role to play in bridging the cultural gap between the patient and the pharmacist, in improving patient referral so that more patients can benefit from pharmaceutical services, and in identifying patients' social determinants of health. CHWs and pharmacists can work synergistically and collaboratively to tailor an intervention to the patient's needs, which can improve and optimize pharmaceutical services, and may ultimately positively impact health outcomes.

Impact of Interventions on Medication Adherence in Patients With Coexisting Diabetes and Hypertension

BACKGROUND

The coexistence of diabetes and hypertension is prevalent due to shared risk factors. Pharmacological treatment has been reported to be effective in managing both conditions. However, treatment effectiveness depends on the extent to which a patient adheres to their treatment. Poor adherence to long-term treatment for chronic diseases is a growing global problem of significant magnitude. Several interventions have been developed to help improve medication adherence in patients with coexisting diabetes and hypertension. This review aimed to determine the characteristics of these interventions and their impact on medication adherence.

METHODS

A systematic review of the literature was conducted using the PRISMA guidelines and registered in the PROSPERO International Registry of Systematic Reviews. Studies were searched in the databases CINAHL, Embase and Medline to identify relevant articles published during 2012-2023. The search concepts included 'medication adherence', 'hypertension', 'diabetes' and 'intervention'. Studies were included if they were in English and evaluated the impact of an intervention aimed at promoting adherence to medications for both diabetes and hypertension.

RESULTS

Seven studies met the inclusion criteria, with five demonstrating a statistically significant improvement in medication adherence. Of the five studies that improved medication adherence, four were multifaceted and one was a single-component intervention. All successful interventions addressed at least two factors influencing non-adherence. Patient education was the foundation of most of the successful interventions, supported by other strategies, such as follow-ups and reminders.

CONCLUSION

Multifaceted interventions that also included patient education had a positive impact on medication adherence in patients with coexisting diabetes and hypertension. Improving adherence in patients with coexisting diabetes and hypertension requires a multipronged approach that considers the range of factors impacting medication-taking.

PATIENT OR PUBLIC CONTRIBUTION

This systematic review provides comprehensive insights into the benefits of patient-centred approaches in intervention development and strengthening. Such patient involvement ensures that medication adherence interventions are more relevant, acceptable and effective, ultimately leading to better health outcomes and more meaningful patient engagement in healthcare research.

Informing an Intervention to Improve Access to Community Pharmacist-Provided Injectable Naltrexone for Formerly Incarcerated Individuals in Wisconsin

In Wisconsin, opioid use disorder (OUD) is highly prevalent among individuals impacted by the criminal justice system. Medications for opioid use disorder (MOUD), including injectable naltrexone, are crucial for treating OUD and especially important for individuals transitioning out of correctional facilities and back into the community. Unfortunately, few formerly incarcerated individuals are able to access MOUD upon community reentry, remaining at high risk of overdose and rearrest. Community pharmacists are a promising resource for providing injectable naltrexone to formerly incarcerated individuals using this treatment option, but are underutilized during reentry planning and by formerly incarcerated individuals upon release. This is due, in large part, to several barriers that exist across the socioecological scale. Accordingly, this study utilized a participatory design process to inform an intervention that address these barriers and improves access to community pharmacist-provided injectable naltrexone for formerly incarcerated individuals upon community reentry. Three iterative focus groups were conducted with five community pharmacists who have experience providing injectable naltrexone and treating formerly incarcerated patients. The goals of each focus group were to: 1) discuss perceptions of existing barriers and prioritize barriers to be addressed, 2) discuss and rank potential interventions to address the prioritized barriers, and 3) discuss components and anticipated challenges related to the prioritized intervention. Focus groups were analyzed via deductive content analysis using a priori categories. Based on discussions of perceived impact and feasibility, the participants prioritized two barriers to be addressed: lack of awareness of community pharmacist-provided injectable naltrexone services and lack of interagency collaboration among primary care clinics, community pharmacies, and correctional facilities. The final intervention included pharmacist-led educational meetings with correctional providers and reentry staff. Several intervention components and anticipated challenges were also identified. Next steps include developing, implementing, and evaluating the efficacy of the intervention on improving access to community pharmacist-provided injectable naltrexone for formerly incarcerated individuals.

Development and Validation of a Tool to Explore Attitudes Towards meDication adHErence Using a Novel Self-Reported QuestionnairE (ADHERE-7)

Despite the availability of various tools for measuring medication adherence, efficiently identifying non-adherence levels and reasons at the point of care remains challenging. Existing tools often lack the ease of use needed for practical clinical application. This study aimed to develop and validate a user-friendly tool to provide healthcare professionals with a concise yet comprehensive means of identifying adherence behaviors. The methodology consisted of two phases: tool items were first developed using the nominal group technique with healthcare professionals, followed by a cross-sectional pilot study involving community-dwelling adults in Croatia. Validation analysis indicated acceptable face and content validity and satisfactory criterion validity, with Attitudes towards meDication adHErence self-Reported questionnairE (ADHERE-7) scores correlating with both the self-reported five-item Medication Adherence Report Scale (MARS-5 tool) (ρ = 0.765; p < 0.001) and an objective measure of the proportion of days covered (PDC) from pharmacy prescription claims data (G = 0.586; p = 0.015). Construct validity revealed three factors: Aversion, Comfort, and Practical Non-Adherence, with Cronbach's alpha values of 0.617 for Aversion and 0.714 for Comfort Non-Adherence. The mean total score for ADHERE-7 was 26.27 ± 2.41 (range 17 to 28). This robust validation process confirms the ADHERE-7 tool as a reliable instrument for assessing medication adherence, addressing aversion, comfort, practical issues, and both intentional and unintentional nonadherence.

Evaluating Greek pharmacists' attitudes and barriers regarding medicines adherence

Adherence constitutes an integral aspect of achieving consistently good clinical results. Understanding pharmacists' perceptions and attitudes, along with existing barriers is essential on the roadmap of enhancing patient adherence. This constitutes the goal of this study.

Methodology

A validated questionnaire was sent to a sample of 280 community pharmacists. Pharmacists were notified both by email and telephone. A response rate of 55% was achieved.

Results

Most pharmacists agree that the identification of patients' suboptimal adherence falls under their professional responsibility and they engage in activities to promote it. There is evidence to support that the most popular interventions were self-management and indirect methods. Specific tools were used to a lesser degree. Finally, the current study illustrated that the most commonly identified barriers were the preference of patients for physicians regarding adherence, lack of information from patients and lack of time.

Conclusion

Although the important role of pharmacists in adherence is ascertained, significant discrepancies in the tools used to control and promote adherence among pharmacists were identified, and also in obstacles faced by themselves and their patients. The interventions should be more consistent and the notion of cooperation among health care professionals should be nurtured.

Assessing Confidence and Competence of Student Pharmacists in a Virtual Medication Adherence Training Program

OBJECTIVE

To assess the impact of a virtual medication adherence training (VMAT) program on students' perceived confidence and perceived competency in delivering medication adherence services via telehealth.

METHODS

This pilot pre-/post-observational study consisted of 2 subsequent sections: (1) 4 asynchronous self-study modules via Canvas (Instructure, Inc.) learning management system, and (2) 2 live application-based sessions involving virtual and telephonic standardized patients. A pre-/post-survey was given to first-, second-, and third-year Doctor of Pharmacy students to assess perceived confidence and perceived competence. Participants completed a 5-question multiple-choice quiz before and after each module to assess knowledge.

RESULTS

Students' overall perceived confidence and perceived competency significantly increased upon completing VMAT. Knowledge in each module assessment also significantly improved. During the assessment of performance throughout the live sessions, most participants lost points when resolving issues within the interaction, addressing the need for patient follow-up, and assessing patient knowledge of medication adherence.

CONCLUSION

This novel VMAT suggests that this or similar programs would be beneficial to improve pharmacy students' perceived confidence, perceived competence, and knowledge in delivering virtual medication adherence services in the telehealth setting. The incorporation of such training within the didactic curriculum of doctoral pharmacy programs should be considered to improve patient care skills for future medication experts.

Patient and Community Health Worker (CHW) Perspectives on a CHW-delivered Nutrition Intervention for Low-Income Adults with Hypertension: A Qualitative Study

INTRODUCTION/OBJECTIVES

Adults with food insecurity (FI) face barriers to hypertension management, including difficulty adhering to diet recommendations. Few community health worker (CHW) interventions focus on diet to improve blood pressure. This qualitative study elicited patient and CHW perspectives on healthy eating and a future CHW nutrition intervention for patients with hypertension.

METHODS

Twenty-five patients with hypertension and FI and 5 CHWs participating in a hypertension health coaching program from 5 Boston-area health centers participated in semi-structured interviews from July to September 2023. Interviews were audio recorded, transcribed, and analyzed using the Framework Method.

RESULTS

Themes included: 1) Variable patient knowledge about dietary patterns for hypertension management and low confidence in interpreting nutrition labels; 2) Culture influenced healthy food perception; and 3) Barriers to healthy eating included cost, limited cooking abilities/supplies, and competing demands. Patients and CHWs favored simple nutrition education materials (e.g., traffic light nutrition ranking, healthy meals on a budget). Patients had mixed opinions about CHW-accompanied supermarket visits.

CONCLUSIONS

This study identified culture, knowledge gaps, and budget constraints as factors influencing diet among patients with hypertension and FI. A CHW-delivered intervention could include simplified nutrition education, strategies for healthy eating on a budget, and linkage to community-based food programs.

Cross-training pharmacy personnel as community health workers

Community health workers (CHWs) are frontline public health professionals who assist in bridging patients with resources and other health care team members. There is an increase in demand for CHWs, and cross-training pharmacy personnel (technicians, pharmacists) as CHWs can help with this demand. With the vital role that pharmacy team members already play in their communities, cross-training provides greater potential to help address patients' medication barriers, such as improving medication adherence. Several factors, such as the best implementation model, willingness of pharmacy personnel to take on additional roles, and service reimbursement and sustainability, should be taken into consideration for implementation. Given the potential benefits, CHW training can become another asset for pharmacy personnel to elevate patient care and reduce health care barriers faced by many patients.

Racial and Ethnic Disparities in Community-Based Pharmacies: A Scoping Review

As pharmacy practice shifts its focus toward population health care needs that serve public health, there is a need to understand community-based pharmacies' contributions to the reduction in health disparities. A scoping review was conducted to identify what community-based pharmacies in the United States are doing to target racial and ethnic disparities in community-based pharmacies. Forty-two articles revealed that community-based pharmacy services addressed racial and ethnic inequities in a variety of ways, including the types of interventions employed, as well as the ethnicities and conditions of the sample populations. Future work should focus on ensuring interventions are carried out throughout pharmacy practice and accessible to all racial and ethnic minoritized populations.

Barriers to Lactulose Adherence in Patients with Cirrhosis and Hepatic Encephalopathy

BACKGROUND

Hepatic encephalopathy (HE) is a major cause of mortality and morbidity in patients with cirrhosis. Lactulose non-adherence is one of the most frequently reported precipitants of hospital admission for HE.

AIMS

We aimed to identify which factors contribute most to lactulose non-adherence and propose strategies to promote greater adherence and utilization of lactulose.

METHODS

Participants in this study consisted of patients with cirrhosis who were taking lactulose for prevention of HE. Subjects were administered the Morisky Adherence Scale 8 (MAS-8) and a customized 16-question survey that assessed barriers to lactulose adherence. Results from the MAS-8 were used to stratify subjects into "adherent" and "non-adherent" groups. Survey responses were compared between groups.

RESULTS

We enrolled 129 patients in our study, of whom 45 were categorized as "adherent and 72 were categorized as "non-adherent." Barriers to adherence included large volumes of lactulose, high frequency of dosing, difficulty remembering to take the medication, unpleasant taste, and medication side-effects. Most patients (97%) expressed understanding of the importance of lactulose, and 71% of patients felt that lactulose was working to manage their HE. Hospital admission rates for HE was higher in non-adherent patients, although this difference was not statistically significant.

CONCLUSION

We identified several factors that contribute to lactulose non-adherence among patients treated for HE. Many of these factors are potentially modifiable. Patient and care-giver education are critical to assure adherence. Pharmacists and nurses are an essential but underutilized aspect of education regarding proper medication use.

A Motivational Interviewing Intervention to Improve Adherence to ACEIs/ARBs among Nonadherent Older Adults with Comorbid Hypertension and Diabetes

BACKGROUND

Hypertension and diabetes mellitus are independent risk factors for cardiovascular diseases. Due to the cardioprotective nature of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs), they are recommended for patients with comorbid hypertension and diabetes. However, poor adherence to ACEIs/ARBs among older adults is a major public health concern. This study aimed to assess the effectiveness of a telephonic motivational interviewing (MI) intervention conducted by pharmacy students among a nonadherent older population (≥ 65 years old) with diabetes and hypertension.

METHODS

Patients continuously enrolled in a Medicare Advantage Plan who received an ACEI/ARB prescription between July 2017 and December 2017 were identified. Group-based trajectory modeling (GBTM) was used to identify distinct patterns of ACEI/ARB adherence during the 1-year baseline period: adherent, gaps in adherence, gradual decline, and rapid decline in adherence. Patients from the three nonadherent trajectories were randomized into MI intervention or control group. The intervention consisted of an initial call and five follow-up calls administered by MI-trained pharmacy students and tailored to the baseline ACEI/ARB adherence trajectories. The primary outcome was adherence to ACEI/ARB during the 6- and 12-month periods post-MI implementation. The secondary outcome was discontinuation, defined as no refills for ACEI/ARB during the 6- and 12-month periods post-MI implementation. Multivariable regression analyses examined the impact of MI intervention on ACEI/ARB adherence and discontinuation while adjusting for baseline covariates.

RESULTS

A total of 240 patients in the intervention group and 480 patients as randomly selected controls were included in this study. At 6 months, patients receiving the MI intervention had significantly better adherence (β = 0.06; p = 0.03) compared with the controls. Linear and logistic regression models also showed patients in the intervention group were more likely to be adherent than controls within 12 months of intervention implementation (β = 0.06; p = 0.02 and OR: 1.46; 95% CI 1.05-2.04, respectively). MI intervention did not have any significant impact on the ACEI/ARB discontinuation.

CONCLUSION

Patients who received the MI intervention were more likely to be adherent at 6 and 12 months following the intervention initiation, despite gaps in the follow-up calls due to COVID-19. Pharmacist-led MI intervention is an effective behavioral strategy to improve medication adherence among older adults and tailoring the intervention to past adherence patterns may enhance the intervention effectiveness. This study was registered with the United States National Institutes of Health (ClinicalTrials.gov identifier NCT03985098).

Strategies to Improve Medication Adherence and Blood Pressure Among Racial/Ethnic Minority Populations: A Scoping Review of the Literature from 2017 to 2021

PURPOSE OF REVIEW

To identify intervention strategies that were effective in promoting medication adherence and HTN control among racial/ethnic minority groups in the US.

RECENT FINDINGS

Twelve articles were included in this review and 4 categories of intervention strategies were identified as counseling by trained personnel, mHealth tools, mHealth tools in combination with counseling by trained personnel, and quality improvement. The findings show that interventions delivered by trained personnel are effective in lowering BP and improving medication adherence, particularly for those delivered by health educators, CHWs, medical assistants, and pharmacists. Additionally, the combination of mHealth tools with counseling by trained personnel has the potential to be more effective than either mHealth or counseling alone and report beneficial effects on medication adherence and BP control. This review provides potential next steps for future research to examine the effectiveness of mHealth interventions in combination with support from trained health personnel and its effects on racial disparities in HTN outcomes.

Medication Adherence and Cardiometabolic Control Indicators Among American Indian Adults Receiving Tribal Health Services: Protocol for a Longitudinal Electronic Health Records Study

BACKGROUND

American Indian adults have the highest prevalence of type 2 diabetes (T2D) in any racial or ethnic group and experience high rates of comorbidities. Uncontrolled cardiometabolic risk factors-insulin resistance, resulting in impaired glucose tolerance, dyslipidemia, and hypertension-increase the risk of mortality. Mortality is significantly reduced by glucose- and lipid-lowering and antihypertensive medication adherence. Medication adherence is low among American Indian adults living in non-Indian Health Service health care settings. Virtually nothing is known about the nature and extent of medication adherence among reservation-dwelling American Indian adults who primarily receive their medications without cost from Indian Health Service or tribal facilities. Electronic health records (EHRs) offer a rich but underused data source regarding medication adherence and its potential to predict cardiometabolic control indicators (C-MCIs). With the support of the Choctaw Nation of Oklahoma (CNO), we address this oversight by using EHR data generated by this large, state-of-the-art tribal health care system to investigate C-MCIs.

OBJECTIVE

Our specific aims are to determine, using 2018 EHR data, the bivariate relationships between medication adherence and C-MCIs, demographics, and comorbidities and each C-MCI and demographics and comorbidities; develop machine learning models for predicting future C-MCIs from the previous year's medication adherence, demographics, comorbidities, and common laboratory tests; and identify facilitators of and barriers to medication adherence within the context of social determinants of health (SDOH), EHR-derived medication adherence, and C-MCIs.

METHODS

Drawing on the tribe's EHR (2018-2021) data for CNO patients with T2D, we will characterize the relationships among medication adherence (to glucose- and lipid-lowering and antihypertensive drugs) and C-MCIs (hemoglobin A1c ≤7%, low-density lipoprotein cholesterol <100 mg/dL, and systolic blood pressure <130 mm Hg); patient demographics (eg, age, sex, SDOH, and residence location); and comorbidities (eg, BMI ≥30, cardiovascular disease, and chronic kidney disease). We will also characterize the association of each C-MCI with demographics and comorbidities. Prescription and pharmacy refill data will be used to calculate the proportion of days covered with medications, a typical measure of medication adherence. Using machine learning techniques, we will develop prediction models for future (2019-2021) C-MCIs based on medication adherence, patient demographics, comorbidities, and common laboratory tests (eg, lipid panel) from the previous year. Finally, key informant interviews (N=90) will explore facilitators of and barriers to medication adherence within the context of local SDOH.

RESULTS

Funding was obtained in early 2022. The University of Florida and CNO approved the institutional review board protocols and executed the data use agreements. Data extraction is in process. We expect to obtain results from aims 1 and 2 in 2024.

CONCLUSIONS

Our findings will yield insights into improving medication adherence and C-MCIs among American Indian adults, consistent with CNO's State of the Nation's Health Report 2017 goal of reducing T2D and its complications.

Improving medication adherence in patients with hypertension through pharmacist-led telehealth services

BACKGROUND

Pharmacist-led telehealth services have resulted in improvements in several disease states, including diabetes and conditions requiring anticoagulation. Pharmacists who used telehealth methods to follow up with their patient have noticed an increase in medication adherence.

METHODS

Using PubMed and EBSCO secondary databases, inclusion criteria were any peer-reviewed study design such as randomized controlled trials, literature reviews, systematic reviews, and cohort studies published within the last 10 years. Search terms included pharmacist, telemedicine, telehealth, cardiovascular disease, and medication adherence.

RESULTS

Seventeen articles were reviewed. Most pharmacist interventions for patients with hypertension involving telemedicine, E-Health, or remote monitoring were performed in the outpatient setting. The primary target of most studies consisted of improving medication adherence.

CONCLUSION

Pharmacist services play an integral role in maintaining medication adherence among the hypertensive population. Telehealth is an effective method of communication with patients to ensure their health is maintained, minimizing barriers of access to care.

Risk factors for drug therapy problems among Cambodian Americans with complex needs: a cross-sectional, observational study

Background

Pharmaceutical drug therapy problems (DTPs) are a major public health problem. We examined patient-level risk factors for DTPs among Cambodian Americans.

Methods

Community health workers (CHWs) verbally administered surveys and completed a detailed medication review form with participants. A doctoral-level pharmacist reviewed the form with the patient and CHW to determine DTP number and type (appropriateness, effectiveness, safety, and adherence).

Results

Participants (n = 63) averaged 55 years old, 6 years of education, 52% were married, 87% spoke Khmer at home, with modal household income <$20,000 (41%). The percentage of participants with DTPs was: 45% appropriateness, 25% effectiveness, 64% safety, and 30% adherence, averaging 3.7 DTPs per patient. In multiple regressions, patient characteristics uniquely predicted each type of DTP. In a multiple regression controlling for number of medications, being married reduced total DTPs (IRR = 0.70) and being depressed increased total DTPs (IRR = 1.26).

Conclusions

Vulnerable patients should be prioritized for pharmacist/CHW teams to identify DTPs.

A randomized trial to decrease risk for diabetes among Cambodian Americans with depression: Intervention development, baseline characteristics and process outcomes

Background:

Depression and antidepressant medications are associated with increased risk for type 2 diabetes. It is not known if diabetes can be prevented in the setting of depression. Cambodian Americans have high rates of both depression and diabetes. This paper reports intervention development, experimental design, baseline characteristics, and process outcomes of diabetes prevention interventions for Cambodian Americans with depression, “Diabetes Risk Reduction through Eat, Walk, Sleep and Medication Therapy Management” (DREAM).

Methods:

Participants were aged 35–75, Khmer speaking, at high risk for developing diabetes, and met criteria for likely depression by either a) antidepressant medication and/or b) elevated depressive symptoms at two time-points during a study eligibility period. Treatment arms were: 1) community health educator (CHE) delivered lifestyle intervention called Eat, Walk, Sleep (EWS), 2) EWS plus pharmacist/CHE-delivered medication therapy management (EWS + MTM), and, 3) social services (SS; control).

Results:

188 participants were randomized. Treatment fidelity was high (98% checklist adherence) and on a scale from 0 to 3, participants reported high EWS treatment satisfaction (M = 2.9, SD = 0.2), group cohesion (M = 2.9, SD = 0.3), and therapeutic alliance to CHEs (M = 2.9, SD = 0.2) and to pharmacists (2.9, SD = 0.3). Attendance was challenging but highly successful; in EWS, 99% attended ≥ one session and 86% completed ≥ 24 sessions, M = 27.3 (SD = 3.7) sessions. Of those randomized to EWS + MTM, 98% attended at least one MTM session and 77%) completed ≥ 4 sessions. Retention was high, 95% at 12-month and 96% at 15-month assessments.

Conclusions:

The interventions were successfully implemented. Lessons learned and suggestions for future trials are offered.

A New Case Manager for Diabetic Patients: A Pilot Observational Study of the Role of Community Pharmacists and Pharmacy Services in the Case Management of Diabetic Patients

The adherence of type 2 diabetes mellitus (DM2) patients with an individual care plan (ICP) is often not satisfactory, nor does it allow for a significant improvement in outcome, because of poor accessibility to services, poor integration of pathway articulations, poor reconciliation with the patient’s life, or the lack of a constant reference person. The purpose of this study was to evaluate the contribution of community pharmacists and pharmacy services in improving adherence with periodic controls in DM2. The study was conducted at a rural pharmacy. A sample of 40 patients was calculated with respect to a historical cohort and subsequently enrolled. Clinical and personal data were collected in an electronic case report form. Pharmacists acting as a case manager followed patients carrying out their ICP developed by an attending physician. Some of the activities foreseen by the ICP, such as electrocardiogram, fundus examination, and self-analysis of blood and urine, were carried out directly in the pharmacy by the pharmacist through the use of telemedicine services and point of care units. Activities that could not be performed in the pharmacy were booked by the pharmacist at the accredited units. Examination results were electronically reported by the pharmacist to the attending physician. The primary endpoint was the variation in patient adherence with the ICP compared to a historical cohort. Secondary endpoints were variation in waiting time for the examinations, mean percentage change in glycated hemoglobin (HbA1c) and low-density lipoprotein (LDL) cholesterol levels and blood pressure, impact on healthcare-related costs, and perceived quality of care. Adherence to the ICP significantly increased. Waiting times were reduced and clinical outcomes improved with conceivable effects on costs. Patients appreciated the easier access to services. Community pharmacists and pharmacy services represent ideal actors and context that, integrated in the care network, can really favor ICP adherence and obtain daily morbidity reduction and cost savings through proper disease control and an early diagnosis of complications.
