Retrospective Quality Improvement Study of Insulin-Induced Hypoglycemia and Implementation of Hospital-Wide Initiatives

Effects of preprandial versus postprandial nutritional insulin administration in the inpatient setting

AIMS

Hospitalized patients can have inconsistent nutritional intake due to acute illness, changing diet, or unpredictable meal delivery. The aim of this study was to evaluate whether implementation of a hospital-wide policy shifting nutritional insulin administration from pre-meal to post-meal was associated with changes in glycemic control or length of stay (LOS).

METHODS

This retrospective study performed at a community hospital evaluated adult inpatients receiving nutritional insulin across three time periods. pre-intervention, immediate post-intervention, and distant post-intervention. Outcomes included rates of hypoglycemia (glucose ≤ 70 mg/dL), moderate hypoglycemia (< 54 mg/dL), severe hypoglycemia (≤ 40 mg/dL), severe hyperglycemia (≥ 300 mg/dL), daily mean glucose level, and LOS.

RESULTS

The number of patient-days analyzed across the cohorts were 1948, 1751, and 3244, respectively. After multivariate adjustment, risk of developing any hypoglycemia and severe hypoglycemia significantly decreased over time (p = 0.001 and p = 0.009, respectively). Daily mean glucose increased over time (194.6 ± 62.5 vs 196.8 ± 65.5 vs 199.3 ± 61.5 mg/dL; p = 0.003), but there were no significant differences among rates of severe hyperglycemia (p = 0.10) or LOS (p = 0.74).

CONCLUSIONS

Implementing a hospital-wide shift to postprandial nutritional insulin administration significantly reduced hypoglycemia rates without increasing severe hyperglycemia. This suggests a promising strategy for improving patient safety, but further prospective randomized controlled trials are warranted to confirm these findings.

Inpatient diabetes management

Diabetes mellitus is currently approaching epidemic proportions and disproportionately affects patients in the hospital setting. In the United States, individuals living with diabetes represent over 17 million emergency department visits and 8 million admissions annually. The management of these patients in the hospital setting is complex and differs considerably from the outpatient setting. All patients with hyperglycemia should be screened for diabetes, as in-hospital hyperglycemia portends a greater risk for morbidity, mortality, admission to an intensive care unit, and increased hospital length of stay. However, the definition of hyperglycemia, glycemic targets, and strategies to manage hyperglycemia in the inpatient setting can vary greatly depending on the population considered. Moreover, the presenting illness, changing nutritional status, and concurrent hospital medications often necessitate thoughtful consideration to adjustments of home diabetes regimens and/or the initiation of new insulin doses. This review article will examine core concepts and emerging new literature surrounding inpatient diabetes management, including glycemic targets, insulin dosing strategies, noninsulin medications, new diabetes technologies, inpatient diabetes management teams, and discharge planning strategies, to optimize patient safety and satisfaction, clinical outcomes, and even hospital financial health.

Centers for Medicare & Medicaid Services' Hospital Harm Measures for Severe Hypoglycemia and Hyperglycemia: Is Your Hospital Ready?

Poor inpatient glycemic management is associated with increased lengths of stay and in-hospital morbidity and mortality. Improving inpatient glycemic outcomes can be difficult because there are no standardized benchmarks, and many hospitals lack the capacity to electronically extract and analyze glucose data. The Centers for Medicare & Medicaid Services recently proposed new electronic clinical quality measures to be incorporated into its mandatory Hospital Inpatient Quality Reporting Program. Among these measures is an assessment of hospital harm from severe hypoglycemia and severe hyperglycemia. Hospitals must be ready to collect the necessary data for these new measures by January 2023. The new measures could bring welcome attention to the need to implement guideline-based inpatient glycemic management. However, some hospitals that serve high-risk populations may be at risk for losing funding if they are unable to comply.

Instituting a Successful Discharge Plan for Patients With Type 2 Diabetes: Challenges and Solutions

Achieving target inpatient glycemic management outcomes has been shown to influence important clinical outcomes such as hospital length of stay and readmission rates. However, arguably the most profound, lasting impact of inpatient diabetes management is achieved at the time of discharge-namely reconciling and prescribing the right medications and making referrals for follow-up. Discharge planning offers a unique opportunity to break through therapeutic inertia, offer diabetes self-management education, and institute an individualized treatment plan that prepares the patient for discharge and promotes self-care and engagement. However, the path to a successful discharge plan can be fraught with potential pitfalls for clinicians, including lack of knowledge and experience with newer diabetes medications, costs, concerns over insurance coverage, and lack of time and resources. This article presents an algorithm to assist clinicians in selecting discharge regimens that maximize benefits and reduce barriers to self-care for patients and a framework for creating an interdisciplinary hospital diabetes discharge program.

American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update

OBJECTIVE

The objective of this clinical practice guideline is to provide updated and new evidence-based recommendations for the comprehensive care of persons with diabetes mellitus to clinicians, diabetes-care teams, other health care professionals and stakeholders, and individuals with diabetes and their caregivers.

METHODS

The American Association of Clinical Endocrinology selected a task force of medical experts and staff who updated and assessed clinical questions and recommendations from the prior 2015 version of this guideline and conducted literature searches for relevant scientific papers published from January 1, 2015, through May 15, 2022. Selected studies from results of literature searches composed the evidence base to update 2015 recommendations as well as to develop new recommendations based on review of clinical evidence, current practice, expertise, and consensus, according to established American Association of Clinical Endocrinology protocol for guideline development.

RESULTS

This guideline includes 170 updated and new evidence-based clinical practice recommendations for the comprehensive care of persons with diabetes. Recommendations are divided into four sections: (1) screening, diagnosis, glycemic targets, and glycemic monitoring; (2) comorbidities and complications, including obesity and management with lifestyle, nutrition, and bariatric surgery, hypertension, dyslipidemia, retinopathy, neuropathy, diabetic kidney disease, and cardiovascular disease; (3) management of prediabetes, type 2 diabetes with antihyperglycemic pharmacotherapy and glycemic targets, type 1 diabetes with insulin therapy, hypoglycemia, hospitalized persons, and women with diabetes in pregnancy; (4) education and new topics regarding diabetes and infertility, nutritional supplements, secondary diabetes, social determinants of health, and virtual care, as well as updated recommendations on cancer risk, nonpharmacologic components of pediatric care plans, depression, education and team approach, occupational risk, role of sleep medicine, and vaccinations in persons with diabetes.

CONCLUSIONS

This updated clinical practice guideline provides evidence-based recommendations to assist with person-centered, team-based clinical decision-making to improve the care of persons with diabetes mellitus.

Meeting topics included (1) digital health and the hospital, (2) blood glucose targets, (3) software for inpatient diabetes, (4) surgery, (5) transitions, (6) coronavirus disease and diabetes in the hospital, (7) drugs for diabetes, (8) continuous glucose monitoring, (9) quality improvement, (10) diabetes care and educatinon, and (11) uniting people, process, and technology to achieve optimal glycemic management. This meeting covered new technology that will enable better care of people with diabetes if they are hospitalized.

The Endocrine Hospitalist: Enhancing the Quality of Diabetes Care

The endocrine hospitalist and inpatient diabetes management team increases access to endocrinology consultations and improves glycemic control and quality metrics such as length of stay and hospital readmission. Enhanced glycemic care is needed in both academic and community hospital settings. Endocrine fellowship programs should implement endocrine hospitalist rotations with emphasis on training endocrine fellows to deliver fast-paced inpatient endocrine care. Entrepreneurship, innovation, and a "start-up" culture within the field of Endocrinology should be encouraged and supported by healthcare systems.
