A Journey to Improved Inpatient Glycemic Control by Redesigning Meal Delivery and Insulin Administration

Queensland Inpatient Diabetes Survey (QuIDS): patient experience survey evaluation

BACKGROUND

Measurement of inpatient experience can allow for treatment tailored to patient preferences and needs. The patient experience of diabetes care has not been explored in Queensland hospitals.

AIMS

To investigate the experiences of patients with diabetes when hospitalised using the Queensland Inpatient Diabetes Survey (QuIDS).

METHODS

In 2019 and 2021, patient experience surveys were collected as part of the statewide QuIDS, a cross-sectional study assessing the quality of inpatient care received by people with diabetes in Queensland, Australia. Patient responses were categorised and frequencies reported as percentages. Free text comments were analysed using thematic analysis methods. Pooled descriptive data were presented.

RESULTS

Responses were collected from 27 hospitals in 2019 (n = 526, 52.4% of all patients with diabetes) and 35 hospitals in 2021 (n = 709, 55.5%). Overall, patients were satisfied with their inpatient diabetes care. Areas for improvement identified by surveyed patients include the choice and timing of meals, staff knowledge about diabetes and increased diabetes self-management. Access to a specialist diabetes team was also identified as being potentially underutilised. Patient comments fell into four major themes: communication, food choices, patient autonomy and education.

CONCLUSION

Many patients reported positive inpatient experiences; however, patients also expressed dissatisfaction with their inpatient diabetes care. Our data provide unique insight and an opportunity to improve standards of care and service provision for inpatients with diabetes.

Addressing Hospital-Acquired Hypoglycemia

BACKGROUND

Hospitalized patients who have diabetes often experience hospital-acquired hypoglycemia, a potentially serious adverse event; as a result, management of this condition has become an important quality of care indicator in the inpatient environment. A growing body of research and evidence-based clinical guidelines support proper timing of point of care (POC) blood glucose (BG) measurements, mealtime insulin administration, and meal delivery to reduce the incidence of both hypoglycemic and hyperglycemic events. Monitoring and improving the timing of these three patient care interventions are recognized as a crucial step in the safe and effective care of patients with diabetes.

PURPOSE

The objective of the QI project was to improve the timing of mealtime insulin administration related to bedside BG monitoring and meal delivery for patients with diabetes who receive mealtime insulin; a secondary goal was to decrease the number of episodes of recurrent hypoglycemia. The overall strategy was to change staff members' approach to mealtime insulin management from a series of individual tasks to a process-oriented collaborative approach.

METHODS

Nurses on the medical-surgical unit at one hospital within a large health system formed a QI team with staff members in information technology and food and nutrition services. The team implemented an eight-week QI pilot project (July 3 to August 26, 2017) using a multidisciplinary approach to coordinate between POC BG measurement, mealtime insulin administration, and meal delivery.

RESULTS

More than two years after the hospital-wide rollout of the practice change, follow-up analysis has shown that, on both noncritical and critical care units, recurrent hypoglycemia has decreased. For example, comparing data obtained in a six-month period before the pilot project (November 2016 through April 2017) with the same six-month period in 2018 and 2019, more than a year after the pilot project, the percentage of patient stays (admissions) on noncritical care units in which there was a recurrence of hypoglycemia fell from 41.8% (of 1,162 total hospital admissions) to 35.1% (of 792 total hospital admissions); similarly, the percentage of patient stays on critical care units in which recurrent hypoglycemia occurred decreased from 36.8% to 22.8%.

CONCLUSIONS

Findings suggest that ensuring a consistent 30-minute window between POC BG measurement and meal delivery enabled nursing staff to perform timely POC BG measurements and administer a more optimal mealtime insulin dose. Increasing interdisciplinary communication, collaboration, and awareness of best practice guidelines relating to proper mealtime insulin administration resulted in a sustained improvement in timing between POC BG measurements and mealtime insulin administration and between mealtime insulin administration and meal delivery.

Timing of Insulin with Meals in the Hospital: a Systems Improvement Approach

PURPOSE OF REVIEW

Coordination of glucose monitoring, mealtimes, and insulin delivery in the hospital is complex, involving interactions between multiple key agents and overlapping workflows. The purpose of this review is to evaluate the scope of the problem as well as to assess evidence for interventions.

RECENT FINDINGS

In recent years, there has been an emphasis on systems-based approaches which address multiple contributing components of the problem at once in an effort to more seamlessly integrate workflows. Technological advances, such as decision support systems and advances in automated insulin delivery, and strategies that minimize the need for complex insulin regimens hold promise for future study. Evaluation of the coordination of insulin delivery is limited by a lack of standardized metrics and systematically collected mealtimes. Nevertheless, successful efforts include system-wide multicomponent interventions, though advances in therapeutic approaches may be of value.

Factors Associated With Timely Blood Glucose Testing and Insulin Administration in Patients Receiving Mealtime Insulin Coverage in Medical Surgical Units

Purpose The purpose of the study was to identify the rate and factors associated with timely mealtime capillary blood glucose (CBG) testing and insulin coverage in hospitalized patients with diabetes. Methods A descriptive-correlational design was used with a random sample of patients (n = 77) and nurses (n = 36) on a medicine and a neuroscience unit of a large Magnet hospital. After written consent was obtained, post-meal patient and nurse interviews were conducted to collect information about patient, nurse, and situational factors known to influence timely mealtime diabetes care. Results Timely CBG testing occurred on 85.7% of the patient participants, and 71.4% received timely insulin coverage. Timely CBG testing was associated (unadjusted) with telling the patient care associate to obtain a finger stick (FS) prior to meals and patient off the unit during mealtime. The odds of having insulin administered on time was significantly and independently associated with the nurse caring for fewer patients, patients waiting for insulin prior to eating, and patients knowing pre-meal FS was high. Conclusions One situational factor and 2 patient factors were independently associated with timely insulin coverage prior to meals. Interventions aimed at raising staff awareness of these factors and providing tailored education to patients may improve the odds of having insulin administered on time.

A Systematic Approach for the Prevention and Reduction of Hypoglycemia in Hospitalized Patients

PURPOSE OF REVIEW

Hypoglycemia and severe hypoglycemia (SH) in the inpatient setting are associated with poor outcomes. This review is designed to highlight approaches to predict and prevent inpatient hypoglycemia that has been successfully implemented focusing on developing overlapping policies and procedures that allow safe glycemic management to occur at all levels of the institution.

RECENT FINDINGS

Standardizing point-of-care (POC) testing, nursing protocols, meal delivery, and formulary restriction are useful tools to prevent hypoglycemia. Informatics and real-time alert processes are highly effective tools to reduce hypoglycemia but require a significant investment in time and infrastructure as well as clear policies on how alerts are acted upon. Computerized dosing support technology and continuous glucose monitoring (CGM) technology are an emerging area of investigation showing promising results. Inpatient hypoglycemia is often predictable and preventable and requires institutional support to deliver targeted and safe diabetes care. This requires each institution to do periodic reassessment of policies and technologies. Future research needs to focus on the cost/benefits of interventions including studies of automated dosing algorithms as well as CGM in higher-risk patient populations.

How Low Can You Go? Reducing Rates of Hypoglycemia in the Non-critical Care Hospital Setting

PURPOSE OF REVIEW

The purpose of this review is to discuss strategies to reduce rates of hypoglycemia in the non-critical care setting.

RECENT FINDINGS

Strategies to reduce hypoglycemia rates should focus on the most common causes of iatrogenic hypoglycemia. Creating a standardized insulin order set with built-in clinical decision support can help reduce rates of hypoglycemia. Coordination of blood glucose monitoring, meal tray delivery, and insulin administration is an important and challenging task. Protocols and processes should be in place to deal with interruptions in nutrition to minimize risk of hypoglycemia. A glucose management page that has all the pertinent information summarized in one page allows for active surveillance and quick identification of patients who may be at risk of hypoglycemia. Finally, education of prescribers, nurses, food and nutrition services, and patients is important so that every member of the healthcare team can work together to prevent hypoglycemia. By implementing strategies to reduce hypoglycemia, we hope to lower rates of adverse events and improve quality of care while also reducing hospital costs. Future research should focus on the impact of an overall reduction in hypoglycemia to determine whether the expected benefits are achieved.

The Case for Diabetes Population Health Improvement: Evidence-Based Programming for Population Outcomes in Diabetes

PURPOSE OF REVIEW

The goal of this review is to describe diabetes within a population health improvement framework and to review the evidence for a diabetes population health continuum of intervention approaches, including diabetes prevention and chronic and acute diabetes management, to improve clinical and economic outcomes.

RECENT FINDINGS

Recent studies have shown that compared to usual care, lifestyle interventions in prediabetes lower diabetes risk at the population-level and that group-based programs have low incremental medial cost effectiveness ratio for health systems. Effective outpatient interventions that improve diabetes control and process outcomes are multi-level, targeting the patient, provider, and healthcare system simultaneously and integrate community health workers as a liaison between the patient and community-based healthcare resources. A multi-faceted approach to diabetes management is also effective in the inpatient setting. Interventions shown to promote safe and effective glycemic control and use of evidence-based glucose management practices include provider reminder and clinical decision support systems, automated computer order entry, provider education, and organizational change. Future studies should examine the cost-effectiveness of multi-faceted outpatient and inpatient diabetes management programs to determine the best financial models for incorporating them into diabetes population health strategies.
