A comparison of clinical pharmacist management of type 2 diabetes versus usual care in a federally qualified health center

Outcomes of an Asynchronous Care Model for Chronic Conditions in a Diverse Population: 12-Month Retrospective Chart Review Study

BACKGROUND

Diabetes and hypertension are some of the most prevalent and costly chronic conditions in the United States. However, outcomes continue to lag behind targets, creating further risk of long-term complications, morbidity, and mortality for people living with these conditions. Furthermore, racial and ethnic disparities in glycemic and hypertension control persist. Flexible telehealth programs leveraging asynchronous care allow for increased provider access and more convenient follow-up, ultimately improving critical health outcomes across demographic groups.

OBJECTIVE

We aim to evaluate the 12-month clinical outcomes of participants in the 9amHealth web-based clinic for diabetes and hypertension. We hypothesized that participation in the 9amHealth program would be associated with significant improvements in glycemic and blood pressure (BP) control across a diverse group of individuals.

METHODS

We enrolled 95 patients in a completely web-based care clinic for diabetes and hypertension who received nutrition counseling, health coaching, and asynchronous physician consultations for medication prescribing. Patients received standard or cellular-connected glucose meters and BP cuffs in order to share data. Laboratory tests were completed either with at-home phlebotomy draws or a self-administered test kit. Patients' first and last hemoglobin A1c (HbA1c) and BP results over the 12-month period were compared, and analyses were repeated across race and ethnicity groups.

RESULTS

Among all 95 patients, the average HbA1c decreased by -1.0 (from 8.2% to 7.2%; P<.001) over 12 months of program participation. In those with a baseline HbA1c >8%, the average HbA1c decreased by -2.1 (from 10.2% to 8.1%; P<.001), and in those with a baseline HbA1c >9%, the average HbA1c decreased by -2.8 (from 11% to 8.2%; P<.001). Among participants who identified as a race or ethnicity other than White, the HbA1c decreased by -1.2 (from 8.6% to 7.4%, P=.001). Further examination of subgroups confirmed HbA1c lowering within each race or ethnicity group. In the overall population, the average systolic BP decreased by 17.7 mm Hg (P=.006) and the average diastolic BP decreased by 14.3 mm Hg (P=.002). Among participants self-identifying as a race or ethnicity other than White, the results similarly showed a decrease in BP (average reduction in systolic BP of 10 mm Hg and in diastolic BP of 9 mm Hg).

CONCLUSIONS

A fully web-based model leveraging all-asynchronous physician review and prescribing, combined with synchronous and asynchronous coaching and nutrition support, was associated with clinically meaningful improvement in HbA1c and BP control over a 12-month period among a diverse group of individuals. Further studies should prospectively evaluate the effectiveness of such models among larger populations, assess the longer-term sustainability of these outcomes, and explore financial models to make these types of programs broadly accessible.

Pharmacist impact on evidence-based prescribing of diabetes medications in patients with clinical atherosclerotic cardiovascular disease

BACKGROUND

Including pharmacists on care teams of patients with type 2 diabetes (T2D) has been shown to promote guideline-based prescribing and improve glycemic control, lowering risks of adverse cardiovascular outcomes. Evidence is lacking regarding whether including pharmacists on the care team is associated with the prescribing of GLP-1 receptor agonists (GLP-1 RA) and SGLT-2 inhibitors (SGLT-2i) recommended for use in patients with T2D and atherosclerotic cardiovascular disease (ASCVD).

OBJECTIVE

To assess the association between having a pharmacist on the primary care team of patients with T2D and ASCVD and being prescribed a guideline-recommended GLP-1 RA or SGLT-2i.

METHODS

A cross-sectional analysis of patients with T2D and ASCVD seen by primary care providers at an academic medical center between June 2019 and May 2020 was completed. Patients with prescriptions for GLP-1 RA or SGLT-2i with evidence of cardiovascular benefit were identified and compared between those with pharmacist care vs usual care using multivariable log-binominal regression analyses.

RESULTS

Of 1,497 included patients, 1,283 (85.7%) were in the usual care group (mean age 68.9 years, hemoglobin A1c 7.6%) and 214 (14.3%) in the pharmacist care group (mean age 64.5 years, A1c 9.0%). Of the pharmacist care group, 50.5% were prescribed a GLP-1 RA or SGLT-2i with cardiovascular benefit vs 17.9% in the usual care group (P < 0.001). In multivariable analyses controlling for A1c and other potential confounders, those in the pharmacist care group were 2.15 times as likely to have been prescribed a GLP-1 RA or SGLT-2i than those in the usual care group (adjusted risk ratio 2.15, 95% CI = 1.83-2.52; P < 0.001).

CONCLUSIONS

These data provide preliminary evidence that integrating pharmacists into patient care teams is associated with increased prescribing of guideline-recommended treatment with GLP-1 RA and SGLT-2i in patients with T2D and ASCVD, yet there is room for improvement in prescribing these agents to patients with T2D and ASCVD.

Impact of Ambulatory Care Pharmacist-Led Management on Hemoglobin A1c Values among Patients with Uncontrolled Diabetes in a Primary Care Clinic vs Usual Care over Two Years

Background: Literature has shown the positive impact of ambulatory care pharmacists on diabetes management, yet additional research on clinical outcomes compared to traditional care models is warranted. Objective: The objective of this study is to evaluate the impact of an ambulatory care pharmacist on glycemic control over two years compared to patients who received usual care. Methods: This retrospective cohort study matched patients with a baseline hemoglobin A1c (HgbA1c) ≥8% managed by the ambulatory care pharmacist to patients who received usual care. The primary outcome was the mean change in HgbA1c over two years. The secondary outcomes were to evaluate the difference in (1) the proportion of patients achieving HgbA1c <8%, (2) the proportion of patients achieving blood pressure <130/80 mmHg, (3) mean LDL, (4) the proportion of patients prescribed SGLT2 inhibitors, GLP-1RA, and sulfonylureas, and (5) severe hypoglycemia after two years. Results: Data for 180 patients was analyzed over two years. The mean HgbA1c was 10% at baseline vs 8.2% after two years (adjusted mean change -1.92) among pharmacist-managed patients, compared to 9.9% vs 9% respectively for usual care patients (adjusted mean change -0.98) (p=0.004). Among pharmacist-managed patients, 53.5% achieved HgbA1c <8% compared with 34.2% of usual care patients (p=0.014). There were no statistically significant differences in proportion of patients at goal blood pressure, mean LDL, or hypoglycemia between the two groups. After two years, 18.3% of pharmacist-managed and 5.8% of usual care patients were on an SGLT2 inhibitor (p=0.008), and 46.7% of pharmacist-managed and 9.2% of usual care patients were on a GLP-1RA (p<0.001). No difference was found in sulfonylurea utilization. Conclusion: Patients with HgbA1c >8% managed by an ambulatory care pharmacist had twice the HgbA1c reduction and significantly more utilization of GLP-1RA and SGLT2 inhibitors as compared to controls provided usual care.

Impact of Pharmacist-Led Clinics on Health Outcomes of Patients With Diabetes at a Ministry of Health Diabetes & Endocrinology Center, Saudi Arabia: A Retrospective Study

Objectives: Saudi Arabia is one of the most diabetes-prone countries in the world. The physician‐centered model of care constitutes the standard of care around the country. The study aimed to evaluate the impact of clinical pharmacist care on diabetes management in comparison to standard physician-based care.

Materials and methods: a retrospective chart review was conducted of patients with type 2 diabetes mellitus (T2DM) seen by the clinical pharmacist at the Diabetes & Endocrinology Center, King Fahad Specialist Hospital located in Buraydah, Saudi Arabia between September 2019 to June 2020.

Results: Thirty-two diabetic patients were included. The mean age is 55.75±10.72 years with 65.6% of patients being females. Hemoglobin A1c (HbA1c) was significantly decreased within nine months compared to baseline (9.33±1.80 vs.10.30±1.66), p=0.017.

Conclusions: The multidisciplinary collaborative care involving pharmacists achieved superior diabetes outcomes for patients with diabetes. Involving pharmacists resulted in a significant HbA1c reduction within nine months. Moreover, pharmacists’ care helped optimize medication therapy and decreased the frequency of hypoglycemia.

Optimization of Medication Regimens in Patients with Type 2 Diabetes and Clinical Atherosclerotic Cardiovascular Disease

The American Diabetes Association recommends that patients with type II diabetes and atherosclerotic cardiovascular disease be prescribed an SGLT-2 inhibitor or GLP-1 agonist for cardioprotective benefit. This project assessed the use of these medications in this patient population in a rural clinic by measuring prescribing rates of SGLT-2/GLP-1 therapy before and after pharmacist interventions. Of the 60 patients identified at baseline, 39.39% (13/33) managed by a pharmacist were prescribed SGLT-2/GLP-1 therapy compared to the 14.81% (4/27) who had not seen a pharmacist (p = 0.025). Of the 43 patients that were not on SGLT-2/GLP-1 therapy at baseline, 13 were lost to follow-up and 13 had contraindications. For the 17 remaining patients, pharmacists recommended initiating SGLT-2/GLP-1 therapy and were able to successfully initiate therapy for 9 patients (52.94%). Pharmacist interventions improved the prescription rates from a baseline of 36.17% (17/47) to 55.3% (26/47) (p = 0.002), with SGLT-2/GLP-1 therapy contraindicated in 27.66% (13/47) of patients. This suggests that patients managed by a pharmacist have medication regimens that were optimized at a greater rate and pharmacists can have a positive impact on the appropriate medication usage in this population.

Evaluation of home medication review for patients with type 2 diabetes mellitus by community pharmacists: a randomised controlled trial

BACKGROUND

Successful diabetes treatment requires commitment and understanding of disease management by the patients.

OBJECTIVE

This trial aimed to evaluate the programme effectiveness of home medication review by community pharmacists (HMR-CP) in optimising diabetes care and reducing medication wastage.

METHODS

A randomised controlled trial was conducted on 166 patients with Type 2 Diabetes Mellitus (T2DM) who were randomly assigned to the intervention or control groups. The intervention group received HMR-CP at 0-month, 3-month, and 6-month. The primary outcome was haemoglobin A1c (HbA1c) while clinical outcomes, anthropometric data, and humanistic outcomes were the secondary outcomes. For the intervention group, drug-related problems (DRP) were classified according to the Pharmaceutical Care Network Europe Foundation (PCNE). Medication adherence was determined based on the Pill Counting Adherence Ratio (PCAR). The cost of medication wastage was calculated based on the total missed dose by the T2DM patients multiplied by the cost of medication. General linear model and generalised estimating equations were used to compare data across the different time-points within and between the groups, respectively.

RESULTS

No significant difference was observed in the demographic and anthropometric data at baseline between the two groups except for fasting blood glucose (FBG). There was a significant reduction in the HbA1c (-0.91%) and FBG (-1.62mmol/L) over the study period (p<0.05). A similar observation was noted in diastolic blood pressure (DBP) and total cholesterol (TC) but not in high-density lipoprotein (HDL), and anthropometric parameters. Both utility value and Michigan Diabetes Knowledge Test (MDKT) scores increased significantly over time. As for the intervention group, significant changes in PCAR (p<0.001) and the number of DRP (p<0.001) were noted.

CONCLUSIONS

HMR-CP significantly improved the glycaemic control, QoL, medication adherence, and knowledge of T2DM patients as well as reduced the number of DRP and cost of medication wastage. However, the impact of HMR-CP on certain clinical and anthropometric parameters remains inconclusive and further investigation is warranted.

Perceptions of collaborative care team members on facilitators and barriers to care and glycosylated hemoglobin level as a diabetes quality metric at a federally qualified health center in Texas

OBJECTIVES

Facilitators and barriers to collaborative patient care have been explored in previous studies. Few studies provide information about collaborative care team (CCT) members' roles in treating patients with diabetes and how CCT members should be evaluated for their contributions to diabetes care. To describe the roles and responsibilities of CCT members at CommUnityCare (CUC), a federally qualified health center in Central Texas; identify the facilitators and barriers affecting referrals to other CCT members within CUC; explore the facilitators and barriers to collaborative patient care at CUC; and assess CCT members' perceptions of quality metrics for diabetes care.

METHODS

A cross-sectional design was used. Data was collected by a survey and semistructured interviews of CCT members. The survey (32 questions) assessed roles and responsibilities, including the percentage of time spent on clinic activities, referral criteria, perceptions of quality diabetes care, and facilitators and barriers to care. The interview (32 questions) gathered a description of the CCT member's role, referral process, and ideas for diabetes quality metrics. Descriptive statistics and content analysis were used for data analysis.

RESULTS

Twenty-two CCT members (4 diagnosticians, 4 clinical pharmacists, 4 behavioral health professionals, 4 registered dietitians, 2 community health workers, and 4 care managers) participated in this study. Co-location (54%) and professional relationships with coworkers (32%) facilitated referrals to other CCT members. Appointment availability (32%) and lack of referral criteria knowledge (27%) were barriers to other CCT member referrals. Seventy-five percent of the dietitians and care managers thought that the glycosylated hemoglobin (A1C) level was a good quality metric for diabetes care, followed by 50% of the clinical pharmacists, 25% of the behavioral health counselors, and 0% of the community health workers and diagnosticians.

CONCLUSION

Co-location and professional relationships facilitated referrals to CCT members, whereas lack of CCT member availability and lack of referral criteria knowledge were barriers to CCT referrals. Metrics other than the lowering of the A1C level should be further explored to assess the quality of diabetes care.

Diabetes-Related Patient Outcomes through Comprehensive Medication Management Delivered by Clinical Pharmacists in a Rural Family Medicine Clinic

Two clinical pharmacy faculty members from a college of pharmacy provide comprehensive medication management in a rural family medicine clinic. The data was assessed for patients with diabetes managed by the pharmacists from 1 January 2017 through to 31 December 2019 to determine the service’s impact on patient outcomes. The primary outcome of this study is the change in the goal attainment rates of the three clinical goals of hemoglobin A1c, blood pressure, and appropriate statin therapy after pharmacist intervention. A total of 207 patients were included. At baseline, the patients had an average of 1.13 of the three goals met, improving to an average of 2.02 goals met after pharmacist intervention (p < 0.001). At baseline, 4.8% of the patients had met all three clinical goals, improving to 30.9% after pharmacist intervention (p < 0.001). There were significant improvements for the individual goal attainment rates of hemoglobin A1c (24.15% vs. 51.21%, p < 0.001), blood pressure (42.51% vs. 85.51%, p < 0.001), and appropriate statin therapy (45.89% vs. 65.70%, p < 0.001). This data adds to the evidence supporting the integration of clinical pharmacists into primary care clinics to improve patient outcomes related to diabetes.
