The Impact of Reimbursement for Non-Face-to-Face Chronic Care Management on Health Utilization Among Patients With Type 2 Diabetes in Louisiana

Telehealth Use and Healthcare Utilization Among Individuals with Type 2 Diabetes During the COVID-19 Pandemic: Evidence From Louisiana Medicaid Claims

INTRODUCTION

The impact of telehealth use on healthcare utilization is limited, especially among Medicaid beneficiaries with type 2 diabetes. Considering the rapid adoption of telehealth during the COVID-19 pandemic, this study examined associations between telehealth use and healthcare utilization among Medicaid beneficiaries with type 2 diabetes.

METHODS

Using Louisiana Medicaid claims data from March 2019 to August 2021, the associations were examined using a difference-in-difference model with propensity score weighting. Demographic characteristics, baseline comorbidities and healthcare utilization, and zip code level environmental factors were included in the analysis. The monthly frequency of healthcare services, including in-person outpatient visits, inpatient visits, emergency department (ED) visits and hemoglobin A1C (HbA1C) tests, were measured as outcomes. Several sensitivity analyses were conducted across different subgroups.

RESULTS

We included 48,992 beneficiaries with type 2 diabetes in the study of 27,340 beneficiaries in the telehealth group and 21,652 beneficiaries in the non-telehealth group. Of 1000 beneficiaries per month, the telehealth group had significantly more utilization compared to the non-telehealth group, with an increase of 195.049 in-person outpatient visits (95% CI: 166.169 to 223.929, p < 0.001), 3.816 inpatient visits (95% CI: 2.539 to 5.093, p < 0.001), 10.499 ED visits (95% CI: 7.287 to 13.712, p < 0.001) and 14.153 HbA1c tests (95% CI: 11.431 to 16.875, p < 0.001, respectively. Excluding beneficiaries who had ED or inpatient visits in the 30 days prior to receiving telehealth visits, overall ED visits significantly decreased for the telehealth group versus the non-telehealth group over time, by 9.456 visits (95% CI: - 12.356 to - 6.557, p < 0.001) per 1000 beneficiaries per month on average.

CONCLUSION

The study found that telehealth was associated with a significant increase in healthcare utilization in general but has the potential to decrease ED and inpatient utilization for some groups among low-income populations with diabetes.

Telehealth use and its impact on clinical outcomes in patients with type 2 diabetes during the COVID-19 pandemic

AIM

To evaluate the impact of telehealth use during the COVID-19 pandemic on glycaemic control and other clinical outcomes among patients with type 2 diabetes.

METHODS

We used electronic health records from the Research Action for Health Network (REACHnet) database for patients with type 2 diabetes who had telehealth visits and those who only received in-person care during the pandemic. A quasi-experimental method of difference-in-difference with propensity-score weighting was implemented to mitigate selection bias and to control for observed factors related to telehealth use. Outcomes included glycated haemoglobin (HbA1c) and other clinical measures (low-density lipoprotein [LDL] cholesterol, blood pressure [BP], and body mass index [BMI]).

RESULTS

Patients using telehealth had better HbA1c control compared to those receiving in-person care only during the pandemic. The telehealth group saw a significant average decrease of 0.146% (95% confidence interval [CI] -0.178% to -0.1145%; P < 0.001) in HbA1c levels over time. The proportion of patients with average HbA1c levels >7% decreased by 0.023 (95% CI -0.034, -0.011; P < 0.001) in the treatment group relative to the comparison group. Modest benefits in the control of LDL cholesterol levels, diastolic BP, and BMI were found in association with telehealth use.

CONCLUSIONS

Our findings suggest that telehealth services contributed to better glycaemic control and management of other clinical outcomes in patients with type 2 diabetes during the pandemic. Factors unmeasured in this study would need to be further explored to better understand the impact of telehealth.

Ambulatory Care Coordination Data Gathering and Use

Care coordination is a crucial component of healthcare systems. However, little is known about data needs and uses in ambulatory care coordination practice. Therefore, the purpose of this study was to identify information gathered and used to support care coordination in ambulatory settings. Survey respondents (33) provided their demographics and practice patterns, including use of electronic health records, as well as data gathered and used. Most of the respondents were nurses, and they described varying practice settings and patterns. Although most described at least partial use of electronic health records, two respondents described paper documentation systems. More than 25% of respondents gathered and used most of the 72 data elements, with collection and use often occurring in multiple locations and contexts. This early study demonstrates significant heterogeneity in ambulatory care coordination data usage. Additional research is necessary to identify common data elements to support knowledge development in the context of a learning health system.

Avenues for Strengthening PCORnet's Capacity to Advance Patient-Centered Economic Outcomes in Patient-Centered Outcomes Research (PCOR)

PCORnet, the National Patient-Centered Clinical Research Network, provides the ability to conduct prospective and observational pragmatic research by leveraging standardized, curated electronic health records data together with patient and stakeholder engagement. PCORnet is funded by the Patient-Centered Outcomes Research Institute (PCORI) and is composed of 8 Clinical Research Networks that incorporate at total of 79 health system "sites." As the network developed, linkage to commercial health plans, federal insurance claims, disease registries, and other data resources demonstrated the value in extending the networks infrastructure to provide a more complete representation of patient's health and lived experiences. Initially, PCORnet studies avoided direct economic comparative effectiveness as a topic. However, PCORI's authorizing law was amended in 2019 to allow studies to incorporate patient-centered economic outcomes in primary research aims. With PCORI's expanded scope and PCORnet's phase 3 beginning in January 2022, there are opportunities to strengthen the network's ability to support economic patient-centered outcomes research. This commentary will discuss approaches that have been incorporated to date by the network and point to opportunities for the network to incorporate economic variables for analysis, informed by patient and stakeholder perspectives. Topics addressed include: (1) data linkage infrastructure; (2) commercial health plan partnerships; (3) Medicare and Medicaid linkage; (4) health system billing-based benchmarking; (5) area-level measures; (6) individual-level measures; (7) pharmacy benefits and retail pharmacy data; and (8) the importance of transparency and engagement while addressing the biases inherent in linking real-world data sources.

The Impact of Reimbursement for Non-Face-to-Face Chronic Care Management on Comprehensive Metabolic Biomarkers Among Multimorbid Patients With Type 2 Diabetes

AIMS

We evaluated the impact of reimbursement for non-face-to-face chronic care management (NFFCCM) on comprehensive metabolic risk factors among multimorbid Medicare beneficiaries with type 2 diabetes in Louisiana.

MATERIALS AND METHODS

We implemented a propensity score method to obtain comparable treatment (n=1501 with NFFCCM) and control (n=17,524 without NFFCCM) groups. Patients with type 2 diabetes were extracted from the electronic health records stored in REACHnet. The study period was from 2013 to February 2020. The comprehensive metabolic risk factors included the primary outcome of glycated hemoglobin (HbA1c) (as the primary outcome) and the secondary outcomes of body mass index (BMI), systolic blood pressure (BP), and low-density lipoprotein cholesterol.

RESULTS

Receiving any NFFCCM was associated with improvement in all outcomes measures: a reduction in HbA1c of 0.063% (95% CI: 0.031%-0.094%; P <0.001), a reduction in BMI of 0.155 kg/m 2 (95% CI: 0.029-0.282 kg/m 2 ; P =0.016), a reduction in systolic BP of 0.816 mm Hg (95% CI: 0.469-1.163 mm Hg; P <0.001), and a reduction in low-density lipoprotein cholesterol of 1.779 mg/dL (95% CI: 0.988 2.570 mg/dL; P <0.001). Compared with the control group, the treatment group had 1.6% more patients with HbA1c <7% (95% CI: 0.3%-2.9%; P =0.013).

CONCLUSIONS

Patients with diabetes in Louisiana receiving NFFCCM experienced better control of HbA1c, BMI, BP, and low-density lipoprotein outcomes.
