Abstract Introduction: The control and evaluation of glycemic levels in critically ill patients is a challenge and a responsibility of the nursing team; therefore, determining the consequences of this during hospitalization is key to demonstrate the importance of timely management. Objective: To determine the relationship between unstable glycemia (hyperglycemia and hypoglycemia), hospital length of stay, and the hospitalization outcome of patients in an Intensive Care Unit (ICU). Methods: A prospective cohort study conducted with 62 critically ill patients by convenience sampling between March and July 2017. Daily blood samples were collected to measure glycemia. The correlation of unstable glycemia with the hospital length of stay and the hospitalization outcome was assessed using Pearson's chi-square. A p-value <0.05 was considered significant. Results: Among the 62 patients, 50% were male and 50% were female. The mean age was 63.3 years (±21.4 years). The incidence of unstable glycemia was 45.2% and was associated with a longer ICU stay (p<0.001) and a progression to death as a hospitalization outcome (p=0.03). Conclusion: Among critically ill patients, unstable glycemia was associated with an extended hospital length of stay and a progression to death, emphasizing the importance of nursing intervention to prevent its occurrence.

Nurse-managed basal-bolus versus sliding-scale insulin regimen in subjects with hyperglycemia at admission for orthopedic surgery: a propensity score approach.

AIMS: A sliding-scale (SS) regimen is discouraged to correct hyperglycemia in hospital patients, but there is resistance to adoption of basal-bolus (BB) treatment in surgical units. We tested the feasibility and the effects of a nurse-based BB regimen in orthopedic surgery. METHODS: Following an intense training to implement a protocol amenable by nurses, a group of patients admitted with hyperglycemia in an orthopedic institute were prospectively followed according to a basal-bolus insulin regimen (BB, n = 80). They were compared with a hyperglycemic group eventually treated by sliding-scale insulin on demand (SS, n = 122). Diabetes was present in 196 cases. Metabolic control was assessed during the first 3 days of surgery; outcome data were tested by logistic regression, after adjusting for propensity score. RESULT: Average blood glucose and glucose variability were lower in BB versus SS (P < 0.001), in the presence of similar 3-day insulin doses. Complications were recorded in 68 cases (16.2% vs. 45.1% in BB and SS, respectively). BB regimen was associated with propensity-adjusted reduction in all adverse events [odds ratio (OR) 0.36; 95% confidence interval (CI) 0.17-0.76] and of systemic infections (OR 0.18; 95% CI 0.07-0.50) and with shorter hospital stay (8.8 ± SD 5.2 days vs. 12.5 ± 7.4; P < 0.01). The superiority of BB regimen was confirmed in the pair-matched analysis. CONCLUSIONS: The study proves the feasibility and the superiority of nurse-based BB versus SS treatment in metabolic control and on the risk of adverse events in orthopedic surgery patients with hyperglycemia.

Strict versus liberal insulin therapy in the cardiac surgery patient: An evidence-based practice development, implementation and evaluation project.

BACKGROUND: Hyperglycemia post-cardiac surgery is associated with poor clinical outcomes. Recent studies suggest maintaining liberal glycemic control (<180mg/dL) using a continuous insulin infusion (CII) versus strict control achieves optimal outcomes and prevents hypoglycemia. PURPOSE: To develop, implement and evaluate a nurse managed liberal CII protocol. METHODS: Retrospective review of 144 strict CII patient records and 147 liberal CII patient records. RESULTS: Mean blood glucose was 159.8mg/dL (liberal CII) compared to 143.3mg/dL (strict CII) (p≤0.001). No surgical site infections occurred in either group. Mean ICU length of stay was 4.5days (liberal) versus 4.4days (strict) (p=0.74). Two 30-day mortalities occurred for the liberal cohort compared to no deaths in the strict group (p=0.49). Hypoglycemia incidence within 24h after surgery was 0.1% (liberal) compared to 0.3% (strict) compared to (p=0.16). CONCLUSION: Use of a nurse managed liberal CII resulted in similar outcomes with fewer incidents of hypoglycemia.

The Importance of Glycemic Control in the Hospital and the Role of the Infusion Nurse.

Diabetes is reaching epidemic proportions. Patients undergoing surgery, regardless of diabetes history, are at high risk for complications of poor glycemic control, including infection, mortality, and longer lengths of stay. This article provides an overview of the evidence about glycemic control in the hospital, risk factors for hyperglycemia and hypoglycemia, and the role of infusion nurses in improving outcomes for hospitalized patients with diabetes.

Controlling Malglycemia in Patients Undergoing Treatment for Cancer.

Patients with or without preexisting diabetes undergoing treatment for cancer may be at risk for malglycemic events. Malglycemia, particularly hyperglycemia and diabetes in patients with cancer, may lead to adverse outcomes. Prevention, prompt recognition, and early intervention to regulate malglycemia can optimize the effects of cancer treatment, minimize the harmful consequences, and improve quality of life for patients with cancer. The development of evidence-based standards of care and protocols are needed to guide clinical practice when caring for patients with cancer.

Evaluation of a Nurse-Managed Insulin Infusion Protocol.

BACKGROUND: The purpose of this study was to evaluate the performance of an insulin infusion protocol targeting a blood glucose (BG) level of 140-180 mg/dL and to characterize protocol adherence. MATERIALS AND METHODS: This was a retrospective observational cohort study including patients for whom the protocol was ordered from January 2012 to May 2013. Performance metrics were assessed in all patients and in patients with an initial BG level of ≥200 mg/dL. Protocol adherence was assessed in a random subset of 50 patients without hypoglycemia and in all hypoglycemic patients. RESULTS: In patients with an initial BG level of ≥200 mg/dL, the mean time to goal was 7.1 h. The rate of decline of BG level in the first 6 h was 16.4 mg/dL/h. Mean BG level was 167 mg/dL, with 43.9% of BG values within goal and 80.3% between 80 and 199 mg/dL. The rate of hypoglycemic events was 0.14 per 100 h. The mean protocol violation rate was higher in patients with hypoglycemia compared with those without (39.8 vs. 23.5 per 100 h, P = 0.002), and 60.7% of hypoglycemic events were attributable to protocol violations. The protocol violation rate (42.8 vs. 17.6 per 100 h; P < 0.001) and the odds of hypoglycemia (odds ratio = 5.2; 95% confidence interval, 1.6, 16.5) were higher in the cardiac surgery patients compared with other patients. CONCLUSIONS: This protocol provides adequate BG control within the clinically acceptable range of 80-199 mg/dL but not within the narrower range of 140-180 mg/dL, with a low incidence of hypoglycemia. Risk factors for hypoglycemia and barriers to protocol adherence in the cardiac surgery population should be elucidated.

The anaesthetic practitioner and type 1 diabetes mellitus.

Type 1 diabetes mellitus (T1DM) is a serious lifelong condition affecting many people in the UK. With the increasing prevalence of T1DM, it is inevitable that more patients will present for anaesthesia and surgery. This article will inform anaesthetic practitioners about the condition, the challenges involved with glycaemic control, complications such as hyperglycaemia and hypoglycaemia, and the importance of maintaining good glycaemic control. It will offer advice about what anaesthetic practitioners can do to help manage and care for their patients.

The impact of hyperglycemia on hematopoietic cell transplantation outcomes: an integrative review.

PROBLEM IDENTIFICATION: Many patients undergoing hematopoietic cell transplantation (HCT) for hematologic malignancies experience hyperglycemic events during treatment, leading to adverse outcomes. Understanding how hyperglycemia during the acute HCT treatment phase impacts outcomes is vital for preventing and mitigating adverse events. This integrative review evaluates the impact of hyperglycemia on adult patients undergoing HCT. LITERATURE SEARCH: PubMed, MEDLINE®, and CINAHL® electronic databases were used to identify relevant articles.Data Evaluation: The final sample for this integrative review included 12 empirical quantitative reports of clinical patient outcomes. Of the 12, 10 are retrospective, 1 is case-control, and 1 is prospective. DATA ANALYSIS: Content analysis was used to synthesize and summarize findings.Presentation of Findings: A review of published literature found associations between hyperglycemia and infection, time to engraftment, development of acute graft-versus-host disease, length of stay, and overall survival. Patient-related risk factors for hyperglycemia included older age, preexisting diabetes, and insulin resistance (i.e., prediabetes). Patients of normal weight experiencing hyperglycemia had worse outcomes than patients who were overweight or obese. Treatment-related risk factors for hyperglycemia include dose and duration of immunosuppressants, specifically corticosteroids, treatment with antihyperglycemic medications, and use of total parenteral nutrition. IMPLICATIONS FOR NURSING PRACTICE: HCT is one of the most complex treatments for hematologic disorders. The transplantation nurse, as part of an interdisciplinary team, plays an essential role in glycemic control during the acute phase of HCT. Understanding the effects of hyperglycemia, as well as factors that place the patient at risk for hyperglycemia, allows the nurse to make well-informed, proactive interventions aimed at glycemic control.

Impact of malglycemia on clinical outcomes in hospitalized patients with cancer: a review of the literature.

PURPOSE/OBJECTIVES: To examine empirical research regarding the role of malglycemia (hyperglycemia, hypoglycemia, or glycemic variability) on clinical outcomes among hospitalized patients with cancer. DATA SOURCES: Research articles were obtained from the Ovid, PubMed, and CINAHL® databases. Key words used in the search included hyperglycemia or malglycemia and neoplasm combined with venous thromboembolism, infection, or mortality. DATA SYNTHESIS: Eleven research articles were examined reporting the impact of malglycemia on various outcomes, including infection, mortality or survival, length of hospital stay, and toxicity. CONCLUSIONS: Findings suggest that malglycemia may have a negative impact on outcomes for hospitalized patients with cancer. Increased rates of infection, mortality, length of stay, and toxicities, as well as decreased survival, were reported. IMPLICATIONS FOR NURSING: Oncology nurses play an important role in the identification of patients with malglycemia. Early assessment and intervention for those patients can improve outcomes and quality of life.

Malglycemia and cancer: introduction to a conceptual model.

PURPOSE/OBJECTIVES: To introduce a conceptual model detailing the physiologic contributions of malglycemia to cancer formation and increased morbidity and mortality. DATA SOURCES: A literature search was conducted using the PubMed, CINAHL®, and Cochrane databases, as well as Surveillance, Epidemiology and End Results (SEER) cancer statistics. DATA SYNTHESIS: Multiple complex factors are associated with malignancy formation, proliferation, and outcomes for each individual. The authors present a model, termed the Malglycemia Orbit Model, that is analogous to an atom, centered on a core of individual factors, and surrounded by "orbits" containing cancer and related factors. Highlighted in this model is the role of malglycemia. CONCLUSIONS: Cancer formation and sequelae involve numerous multifaceted factors. One factor not well described or understood within the context of malignancies is glycemic status, most notably how malglycemia impacts cancer formation and risks for adverse outcomes. The atomic-structured malglycemia model describes this process. IMPLICATIONS FOR NURSING: Among the many uncontrollable factors that contribute to cancer formation and adverse outcomes, malglycemia is one that is modifiable. Nurses are in a prime position to conduct research to enhance understanding and ultimately improve protocols for better glycemic control and, in effect, better outcomes for individuals with cancer.

One institution's experience in implementing protocols for glycemic management.

The objective for monitoring blood glucose is to determine the need for intervention. This article describes an institution's comprehensive program of protocols and education initiated to manage inpatient hyperglycemia.

Perioperative blood glucose control during adult coronary artery bypass surgery.

Coronary artery bypass graft (CABG) procedures are among the most frequently performed surgical procedures in the United States. People with cardiovascular disease who also have diabetes have a greater risk of poor outcomes after CABG procedures than patients who do not have diabetes. This literature review examines current information regarding perioperative blood glucose (BG) control. It emphasizes BG control in adults during the hypothermic period of cardiopulmonary bypass. Hyperglycemia, not the diagnosis of diabetes, significantly increases the risk of adverse clinical outcomes, longer hospitalizations, and increased health care costs.

[Changes in the blood glucose of revascularized patients in the immediate postoperative period]. / Alteraciones de la glucemia en los pacientes revascularizados en el posoperatorio inmediato.

Variability in glycaemia in revascularized patients in the immediate postoperative period was studied in order to determine the presence of hyperosmolar hyperglycaemia coma, ketogenic and non-ketogenic, and the relation with hemodynamic changes. It was found that 15 patients (9.2%) from the Arteriology Service and two patients (7.1%) from the Diabetes Angiopathy Service had a non-ketogenic hyperglycaemic hyperosmolar coma and there was no ketogenic hyperglycaemic hyperosmolar coma. There were 32 patients (16.8%) with hemodynamic changes who had mild and moderate hyperglycaemia in the immediate postoperative period.
