Quality Metrics and Health Care Utilization for Adult Patients with Sickle Cell Disease

Use of Epic Electronic Health Record System for Health Care Research: Scoping Review

BACKGROUND

Electronic health records (EHRs) enable health data exchange across interconnected systems from varied settings. Epic is among the 5 leading EHR providers and is the most adopted EHR system across the globe. Despite its global reach, there is a gap in the literature detailing how EHR systems such as Epic have been used for health care research.

OBJECTIVE

The objective of this scoping review is to synthesize the available literature on use cases of the Epic EHR for research in various areas of clinical and health sciences.

METHODS

We used established scoping review methods and searched 9 major information repositories, including databases and gray literature sources. To categorize the research data, we developed detailed criteria for 5 major research domains to present the results.

RESULTS

We present a comprehensive picture of the method types in 5 research domains. A total of 4669 articles were screened by 2 independent reviewers at each stage, while 206 articles were abstracted. Most studies were from the United States, with a sharp increase in volume from the year 2015 onwards. Most articles focused on clinical care, health services research and clinical decision support. Among research designs, most studies used longitudinal designs, followed by interventional studies implemented at single sites in adult populations. Important facilitators and barriers to the use of Epic and EHRs in general were identified. Important lessons to the use of Epic and other EHRs for research purposes were also synthesized.

CONCLUSIONS

The Epic EHR provides a wide variety of functions that are helpful toward research in several domains, including clinical and population health, quality improvement, and the development of clinical decision support tools. As Epic is reported to be the most globally adopted EHR, researchers can take advantage of its various system features, including pooled data, integration of modules and developing decision support tools. Such research opportunities afforded by the system can contribute to improving quality of care, building health system efficiencies, and conducting population-level studies. Although this review is limited to the Epic EHR system, the larger lessons are generalizable to other EHRs.

Assessing barriers and facilitators to transition in sickle cell disease care prior to implementation of a formalized program

Over 95% of children with sickle cell disease (SCD) survive into adulthood in the United States. However, early mortality remains a problem, especially in persons between the ages of 18 and 35. One possible explanation for the increased mortality rate in young adults is difficulties in engaging in care during the transition from a heavily contiguous pediatric healthcare model to a more self-reliant adult healthcare model. The goal of this study was to identify potential facilitators and barriers to a successful transfer in care from the pediatric to adult SCD program before the formation of a formal transition program. This is a retrospective cohort study of transition outcomes for 472 individuals with SCD (all genotypes) treated at the University of Alabama at Birmingham (UAB) sickle cell clinic (aged 18-24). The primary outcome was whether the patient continued care in (any) adult SCD program (defined as being seen at least once in an adult hematology/SCD clinic). One hundred eighty-eight (45%) transition age patients successfully transferred to adult care. Facilitators to successful transfer in care included being treated at the same hospital for both pediatric and adult programs, having the genotype HbSS, and/or receiving an SCD-modifying therapy at the time of transition (hydroxyurea and/or red cell transfusion therapy). Of primary interest, many of the patients who failed to transition to an adult clinic were lost to follow-up prior to 15 years of age. Importantly, these patients who had previously been labeled as "transition failures," were lost to follow-up long before the transition age. Early engagement is needed for this population.

Building access to care in adult sickle cell disease: defining models of care, essential components, and economic aspects

Sickle cell disease (SCD) is the most common inherited blood disorder in the United States. It is a medically and socially complex, multisystem illness that affects individuals throughout the lifespan. Given improvements in care, most children with SCD survive into adulthood. However, access to adult sickle cell care is poor in many parts of the United States, resulting in increased acute care utilization, disjointed care delivery, and early mortality for patients. A dearth of nonmalignant hematology providers, the lack of a national SCD registry, and the absence of a centralized infrastructure to facilitate comparative quality assessment compounds these issues. As part of a workshop designed to train health care professionals in the skills necessary to establish clinical centers focused on the management of adults living with SCD, we defined an SCD center, elucidated required elements of a comprehensive adult SCD center, and discussed different models of care. There are also important economic impacts of these centers at an institutional and health system level. As more clinicians are trained in providing adult-focused SCD care, center designation will enhance the ability to undertake quality improvement and compare outcomes between SCD centers. Activities will include an assessment of the clinical effectiveness of expanded access to care, the implementation of SCD guidelines, and the efficacy of newly approved targeted medications. Details of this effort are provided.

Patient Perspectives of Sickle Cell Management in the Emergency Department

Sickle cell disease (SCD) is a common genetic blood disorder predominantly affecting African Americans in the United States. The objective of this study was to use a multimethods approach to describe how patients with SCD in North Carolina perceive the care they receive in emergency departments (EDs). Fourteen participants completed an interview (n = 10) or 2 focus groups (n = 2 per focus group) and 51 completed surveys. Sixty percent of participants with pain attack "very much" or "quite a bit" avoided going to the ED for care because of prior bad experiences and 50% of participants reported waiting 120 minutes or more in the ED for treatment of their sickle cell pain. Participants reported that stigma associated with provider perception of drug-seeking behavior is a persistent problem in the ED. Participant recommendations warrant further investigation to address persistent SCD quality-of-care concerns in the ED.

Patient-Reported Outcomes and Economic Burden of Adults with Sickle Cell Disease in the United States: A Systematic Review

Purpose

To systematically estimate the patient-reported outcomes (PROs) and economic burden of sickle cell disease (SCD) among adults in the United States (US).

Patients and Methods

Two systematic literature reviews (SLRs), one each for the PROs and economic topics, were performed using MEDLINE and Embase to identify observational studies of adults with SCD. Included studies were published between 2007 and 2018 and evaluated health-related quality of life (HRQL), function, healthcare resource utilization (HCRU), or costs. Given the high degree of clinical and methodological heterogeneity, findings were summarized qualitatively.

Results

The SLRs identified 7 studies evaluating the PROs and 15 studies evaluating the economic burden meeting the pre-specified selection criteria. The PRO evidence showed the prevalence of depression and anxiety to be 21–33% and 7–36%, respectively, in adults with SCD. The mean SF-36 physical summary scores ranged from 33.6 to 59.0 and from 46.3 to 61.5 for the mental summary scores. Overall HRQL for adults with SCD was poor and significantly worse in those with opioid use. Adult SCD patients were found to have varying rates of emergency department (ED) utilization (0.3–3.5 annual ED visits), hospitalizations (0.5–27.9 per patient per year), and/or readmission (12–41%). Key factors associated with significant HCRU were age, dental infection, and SCD-related complications. SCD specialized care settings and SCD intensive management strategy were reported to significantly decrease the number of hospitalizations.

Conclusion

This systematic evidence synthesis found that disease burden measured by PROs and economic burden of SCD on adults in the US are substantial despite the availability of approved SCD treatments during 2007–2018. The use of hydroxyurea, optimal management with opioids, and employing intensive treatment strategies may help decrease the overall burden to patients and healthcare systems. Published data on costs associated with SCD are limited and highlight the need for more economic studies to characterize the full burden of the disease.

Sickle-Cell Disease Co-Management, Health Care Utilization, and Hydroxyurea Use

BACKGROUND

Sickle-cell disease (SCD) causes significant morbidity, premature mortality, and high disease burden, resulting in frequent health care use. Comanagement may improve utilization and patient adherence with treatments such as Hydroxyurea. The purpose of this study was to describe acute-care utilization in Medicaid-enrolled patients with SCD, patient factors associated with comanagement, and adherence to Hydroxyurea.

METHODS

Data from 2790 patients diagnosed with SCD, age 1 to 65+ years, enrolled at least 1 month in North Carolina Medicaid between March 2016 and February 2017, were analyzed. Outpatient visits were categorized as primary care, hematologist, and nonhematologist specialist. Nurse practitioners or physician assistants with unidentified specialty type or family practice were categorized separately. Comanagement was defined as a minimum of 1 primary care and 1 hematologist visit/patient during the study period.

RESULTS

There were notable age-related differences in utilization of health care services. Only 34.82% of the sample was comanaged. Comanagement was higher in the 1-to-9-year-old (44.88%) and 10-to-17-year-old groups (39.22%) versus the 31-to-45-year-old (30.26%) and 65+-year-old (18.75%) age groups. Age had the greatest influence (AUC = 0.599) on whether or not a patient was comanaged. Only a third of the sample (32.24%) had at least 1 Hydroxyurea (HU) prescription. Age was the most predictive factor of good HUadherence (AUC = 0.6503). Prediction by comanagement was minimal with an AUC = 0.5615.

CONCLUSION

Comanagement was a factor in predicting HUadherence, but further studies are needed to identify the frequency and components of comanagement needed to increase adherence and reduce acute care utilization.
