Abstract
WHAT OTHER GUIDELINES ARE AVAILABLE ON THIS TOPIC Since the publication of the SAMBA Consensus Statement for perioperative blood glucose management in the ambulatory setting in 2010, several recent guidelines have been issued by the American Diabetes Association (ADA), the American Association of Clinical Endocrinologists (AACE), the Endocrine Society, the Centre for Perioperative Care (CPOC), and the Association of Anaesthetists of Great Britain and Ireland (AAGBI) on DM care in hospitalized patients; however, none are specific to ambulatory surgery. HOW DOES THIS GUIDELINE DIFFER FROM THE PREVIOUS GUIDELINES Previously posed clinical questions that were outdated were revised to reflect current clinical practice. Additional questions were developed relating to the perioperative management of patients with DM to include the newer therapeutic interventions.

Impact of Hyperglycemia on Complication and Mortality after Transarterial Chemoembolization for Hepatocellular Carcinoma. Diabetes Metab J 2024; 48:302-311. [PMID: 38171144 PMCID: PMC10995496 DOI: 10.4093/dmj.2022.0255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 02/27/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGRUOUND Current guidelines regarding periprocedural glycemic control to prevent complications after nonsurgical invasive procedures are insufficient. Transarterial chemoembolization (TACE) is a widely used treatment for unresectable hepatocellular carcinoma. We aimed to investigate the association between diabetes mellitus (DM) per se and the degree of hyperglycemia with postprocedural complications after TACE. METHODS A total of 22,159 TACE procedures performed at Seoul National University Hospital from 2005 to 2018 were retrospectively analyzed. The associations between DM, preprocedural glycosylated hemoglobin (HbA1c), and periprocedural average glucose with postprocedural adverse outcomes were evaluated. The primary outcome was occurrence of postprocedural bacteremia. Secondary outcomes were acute kidney injury (AKI), delayed discharge and death within 14 days. Periprocedural glucose was averaged over 3 days: the day of, before, and after the TACE procedures. Propensity score matching was applied for procedures between patients with or without DM. RESULTS Periprocedural average glucose was significantly associated with bacteremia (adjusted odds ratio per 50 mg/dL of glucose, 1.233; 95% confidence interval, 1.071 to 1.420; P=0.004), AKI, delayed discharge, and death within 14 days. DM per se was only associated with bacteremia and AKI. Preprocedural HbA1c was associated with delayed discharge. Average glucose levels above 202 and 181 mg/dL were associated with a significantly higher risk of bacteremia and AKI, respectively, than glucose levels of 126 mg/dL or lower. CONCLUSION Periprocedural average glucose, but not HbA1c, was associated with adverse outcomes after TACE, which is a nonsurgical invasive procedure. This suggests the importance of periprocedural glycemic control to reduce postprocedural complications.

J Oral Maxillofac Surg 2024; 82:364-375. [PMID: 38103577 DOI: 10.1016/j.joms.2023.11.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 11/16/2023] [Accepted: 11/18/2023] [Indexed: 12/19/2023]
Abstract
PURPOSE The preoperative management guidelines of surgical patients are constantly evolving as newer evidence-based research is published. Oral and maxillofacial surgeons need to be current with the increasingly more complex new drug therapies and updated national association(s) guidelines. This narrative review provides a synopsis with important reference tables for updated preoperative optimization guidelines for anticoagulation, antiplatelet therapy, antihypertensive management, and glycemic control in the preoperative period for the oral and maxillofacial surgery patient. It also includes the most current anesthesia guidelines on glucagon-like peptide receptor agonists. METHODS The search strategy utilized pubmed.gov to identify the most recent national society guidelines and review articles pertinent to perioperative anticoagulation, antiplatelet therapy, antihypertensive management, and glycemic control. RESULTS The search identified 75 articles from the American College of Surgeons, American Heart Association, American Society of Anesthesiologists, American College of Cardiologists, in addition to recent reviews discussing the standard of care for optimization of patients in the perioperative period. CONCLUSION Medical optimization prior to surgery is important for safe and efficient surgical practice and has been shown to improve overall mortality. This narrative review provides a summary of the current data with recommendations focusing on four key points.

Preoperative Glycosylated Haemoglobin Screening to Identify Older Adult Patients with Undiagnosed Diabetes Mellitus-A Retrospective Cohort Study. J Pers Med 2024; 14:219. [PMID: 38392652 PMCID: PMC10890067 DOI: 10.3390/jpm14020219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 02/13/2024] [Accepted: 02/16/2024] [Indexed: 02/24/2024] Open
Abstract
More than 25% of older adults in Europe have diabetes mellitus. It is estimated that 45% of patients with diabetes are currently undiagnosed, which is a known risk factor for perioperative morbidity. We investigated whether routine HbA1c screening in older adult patients undergoing surgery would identify patients with undiagnosed diabetes. We included patients aged ≥65 years without a diagnosis of diabetes who visited the preoperative assessment clinic at the Amsterdam University Medical Center and underwent HbA1c screening within three months before surgery. Patients undergoing cardiac surgery were excluded. We assessed the prevalence of undiagnosed diabetes (defined as HbA1c ≥ 48 mmol·mol-1) and prediabetes (HbA1c 39-47 mmol·mol-1). Using a multivariate regression model, we analysed the ability of HbA1c to predict days alive and at home within 30 days after surgery. From January to December 2019, we screened 2015 patients ≥65 years at our clinic. Of these, 697 patients without a diagnosis of diabetes underwent HbA1c screening. The prevalence of undiagnosed diabetes and prediabetes was 3.7% (95%CI 2.5-5.4%) and 42.9% (95%CI 39.2-46.7%), respectively. Preoperative HbA1c was not associated with days alive and at home within 30 days after surgery. In conclusion, we identified a small number of patients with undiagnosed diabetes and a high prevalence of prediabetes based on preoperative HbA1c screening in a cohort of older adults undergoing non-cardiac surgery. The relevance of prediabetes in the perioperative setting is unclear. Screening for HbA1c in older adult patients undergoing non-cardiac surgery does not appear to help predict postoperative outcome.

Abstract
Not meeting recommended A1C targets may be associated with postoperative complications in adults, but there are no studies reporting on the relationship between preoperative A1C and postoperative complications in children with type 1 or type 2 diabetes. The objective of this study was to determine whether elevated A1C levels were associated with an increased incidence of postoperative complications in children with diabetes presenting for elective noncardiac surgery or diagnostic procedures. It found no such association, suggesting no need to delay elective surgery in children with diabetes until A1C is optimized.

Abstract
Background and Aims Increased burden of diabetes in India has resulted in a spurt in the number of patients with diabetes posted for surgeries. The paucity of national guidelines can lead to marked practice variations in the peri-operative management of diabetes. This survey intends to discern current peri-operative practices among anesthesiologists working in medical colleges, tertiary care government, and private health care institutes of the country. Material and Methods An anonymous online survey comprising of 25 closed-ended questions was conducted using Google Forms® and disseminated through social media, emails, and messaging platforms. The questionnaire dealt primarily with the peri-operative management of diabetes in patients scheduled for elective surgery. The survey was conducted over a period of 1 month and targeted anesthesia resident trainees with more than 1-year experience, senior residents, and consultants working in India. Results Statistically significant difference was observed between the three types of health facilities with respect to prior evaluation for diabetes (P = 0.007), prioritizing operative list (P = 0.006), hospital encouragement of day care surgery (P < 0.001), glycated hemoglobin level (HbA1c) level >8.5 for postponement of surgery (P < 0.05), insulin infusion preference (P < 0.001), hourly intra-operatively capillary blood glucose (CBG) assessment (P = 0.021), and avoiding peri-operative use of Ringer's lactate (RL) (P = 0.025). Conclusion This survey primarily highlights the lack of prioritizing the operative list, early discontinuation of metformin, and reduced tendency to consider diabetics for day care surgeries.

Abstract
BACKGROUND Perioperative dysglycemia is associated with adverse surgical outcomes in adults. We sought to determine the association between perioperative dysglycemia and 30-day adverse surgical events in pediatric patients undergoing non-cardiac surgery. METHODS We analyzed records from the American College of Surgeons National Surgical Quality Improvement Program Pediatric (ACS-NSQIP-P) database from 2016 to 2021 at two academic tertiary care hospitals. The primary outcomes were individual 30-day adverse events, composite serious adverse events, composite hospital acquired infections and composite morbidity. RESULTS A total of 5410 records were analyzed: the cohort was 52.6% male and 52.6% non-Hispanic White, and 1472 (27.2%) had dysglycemia. Children undergoing procedures in general surgery (48.4%), neurosurgery (25.4%), and orthopedic surgery (16.0%) had higher rates of dysglycemia compared to other surgical specialties. Patients with dysglycemia were more likely to have surgical site infection (4.3% dysglycemic vs. 3.1% normoglycemic, p = 0.028), cardiac arrest (2.6% vs. 0.1%, p < 0.001), and sepsis (3.7% vs. 1.3%, p < 0.001); more likely to undergo reoperation (11.3% vs. 5.8%, p < 0.001); and more likely to remain hospitalized after 30 days (33.0% vs. 6.1%, p < 0.001). After controlling for patient and case demographics, perioperative dysglycemia was associated with more composite serious adverse events (OR 1.85, 95% CI 1.49-2.29, p = 0.000), composite hospital acquired infections (OR 1.42, 95% CI 1.04-1.93, p = 0.026), and composite morbidity (OR 2.52, 95% CI 2.13-2.97, p = 0.000). CONCLUSIONS Perioperative dysglycemia in children undergoing non-cardiac surgery is associated with increased risk of adverse events and outcomes. Interventions that screen and normalize blood glucose in the perioperative period may mitigate risk and improve quality of care.

Abstract
BACKGROUND Diabetes Mellitus (DM) and its associated immune dysfunction are well-studied risk factors for adverse surgical outcomes. The literature regarding endoscopic sinus surgery (ESS) is less robust and there have been conflicting reports on post-operative complications and surgical results in this patient population. The purpose of this study was to analyze the impact of diabetes mellitus on outcomes after ESS via rates of post-operative medical intervention in the first 6 months after surgery. METHODS This was a retrospective cohort study of 176 subjects who underwent ESS from 2015 to 2019 at a single institution by 2 fellowship-trained rhinologists. Subjects were divided into 2 groups, those with a documented Hemoglobin A1c (HbA1c) >6.5 or diagnosis of DM and those with HbA1C < 6.5. Patient age, demographics, 6-month preoperative HbA1c, surgical status and extent, and 6-monthpostoperative need for steroids and/or antibiotics were collected. RESULTS Out of n = 176 total patients, n = 39 (22.2%) were categorized into the DM group, which were older (46.4 vs 53.8 years, P = .004) and higher proportion of white patients (89.7% vs 68.6%, P = .008). There were no significant differences between the 2 groups in proportion of revision surgery, surgical extent, and post-operative use of antibiotics or steroids. When including all variables in binary logistic regression for use of postoperative antibiotics or steroids, the only significant variable predicting these outcomes was the extent of surgical resection including sphenoid sinus (P = .001, OR [95% CI] = 4.02 [1.73-9.34]) or frontal sinus (P < .001, OR [95% CI = 9.86 [4.00-24.33]). CONCLUSIONS Patients with DM do not appear to have worse post-operative outcomes outside of the initial 6-month postoperative period.

Abstract
PURPOSE Perioperative hyperglycemia is associated with adverse outcomes for patients with and without diabetes. Guidelines and published protocols for intraoperative glycemic management have substantial variation in their recommendations. We sought to characterize the current evidence-guiding intraoperative glycemic management in a scoping review. SOURCES Our search strategy included MEDLINE (Ovid and EBSCO), PubMed, PubMed Central, EMBASE, CINAHL, Cochrane Library, SciVerse Scopus, and Web of Science and a gray literature search of Google, Google Scholar, hand searching of the reference lists of included articles, OAISter, institutional protocols, and ClinicalTrails.gov. PRINCIPAL FINDINGS We identified 41 articles that met our inclusion criteria, 24 of which were original research studies. Outcomes and exposures were defined heterogeneously across studies, which limited comparison and synthesis. Investigators often created arbitrary and differing categories of glucose values rather than analyzing glucose as a continuous variable, which limited our ability to combine results from different studies. In addition, the study populations and surgery types also varied considerably, with few studies performed during day surgeries and specific surgical disciplines. Study populations often included more than one type of surgery, indication, and urgency that were expected to have varying physiologic and inflammatory responses. Combining low- and high-risk patients in the same study population may obscure the harms or benefits of intraoperative glycemic management for high-risk procedures or patients. CONCLUSION Future studies examining intraoperative glycemic management should carefully consider the study population, surgical characteristics, and pre- and postoperative management of hyperglycemia.

Abstract
BACKGROUND The high incidence of intraoperative glucose dysregulations in liver transplantation (LT) is related to the lack of highly orchestrated control of intraoperative blood glucose. Glucose monitoring based on a single arterial blood gas test can only provide a simple glucose profile and is insufficient in monitoring intraoperative glycemic variability (GV), which is not conducive to controlling GV and may have a lag in the management of hyper/hypoglycemia. Continuous glucose monitor (CGM), which has been successfully applied in the management of chronic disease in diabetes, provides more detailed blood glucose records and reflect GV parameters such as coefficient of variation (CV%). However, its effectiveness and accuracy for guiding blood glucose management in major surgeries remains unclear. METHODS This is a single-center, randomized, controlled, superiority trial. One hundred and eighty patients scheduled for orthotopic LT will be recruited and randomized into two groups. All patients are monitored for intraoperative glucose using CGM combined with arterial blood gas (ABG). In the intervention group (group CG), ABG will be performed when CGM value is < 6.1 mmol/L or > 10.0 mmol/L, or the rate of change of CGM value > 1.67 mmol/(L·min). In the control group (group G), intraoperative ABG tests will be performed every 2 h, and the frequency of ABG tests will be adjusted based on the previous arterial glucose result. Patients in both groups will have their blood glucose adjusted according to arterial glucose values and a uniform protocol. Surgical and other anesthetic management is completed according to standard LT practices. DISCUSSION This study intends to investigate the effectiveness of CGM-based intraoperative glucose management and its impact on the prognosis of LT patients by comparing the GV, mean glucose values, and the incidence of hypo/hypoglycemic events guided by the above two glucose monitoring methods. TRIAL REGISTRATION This study is registered at www.chictr.org.cn on January 4, 2022, under the registration number ChiCTR2200055236.

Abstract
OBJECTIVE We evaluated implementation and clinical outcomes of a perioperative glycemic management pathway in gynecologic oncology. METHODS Interrupted time-series analysis was used to compare process, balancing and outcome measures and clinical outcomes from 18 months preimplementation to 18 months postimplementation. RESULTS Compared with in the preimplementation period, the proportion of patients who underwent preoperative screening with glycated hemoglobin in the postimplementation period increased by 11.3% (95% confidence interval [CI], 5.0% to 17.7%; p=0.001). The proportion of patients with diabetes who had at least 1 blood glucose measurement after surgery increased by 15.3% (95% CI, -3.2% to 33.8%; p=0.10). There was no change in the proportion of patients who had any hyperglycemia or moderate or severe hyperglycemia. The median length of stay decreased by 0.42 days (95% CI, -0.91 to 0.07 days; p=0.09). There were major quality gaps in perioperative glycemic management that did not clearly improve after implementation of a multidisciplinary care pathway. CONCLUSION Optimal strategies for improvement of perioperative glycemic management are not yet known.

Preoperative hyperglycemia is associated with elevated risk of perioperative ischemic stroke in type 2 diabetic patients undergoing non-cardiovascular surgery: A retrospective cohort study. Front Aging Neurosci 2022; 14:990567.

Abstract
BACKGROUND Diabetes mellitus (DM) has been reported to be associated with perioperative stroke, but the effects of preoperative hyperglycemia on the risk of perioperative stroke in diabetic patients undergoing non-cardiovascular surgery remain unclear. This study investigated the association between preoperative hyperglycemia and the risk of perioperative ischemic stroke in type 2 diabetic patients undergoing non-cardiovascular surgery. METHODS This retrospective cohort study screened 27,002 patients with type 2 DM undergoing non-cardiovascular surgery with general anesthesia between January 2008 and August 2019 at The First Medical Center of Chinese People's Liberation Army (PLA) General Hospital. The exposure of interest was preoperative hyperglycemia, defined as a fasting plasma glucose (FPG) ≥ 7 mmol/L. The outcome of interest was a new diagnosis of perioperative ischemic stroke within 30 days after surgery. Residual confounding was minimized by controlling for observable patient and intraoperative factors. Logistic regression was conducted in the total and propensity score matched cohorts. In addition, we stratified patients into six subgroups to investigate whether the association between preoperative hyperglycemia and perioperative ischemic stroke differs in these subgroups. RESULTS The overall incidence of perioperative ischemic stroke was 0.53% (n = 144) in the current cohort. The odds of perioperative ischemic stroke were significantly increased for patients with preoperative hyperglycemia after adjusting for patient- related variables (OR: 1.95; 95% CI: 1.39-2.75; p < 0.001), surgery-related variables (OR: 2.1; 95% CI: 1.51-2.94; p < 0.001), and all confounding variables (OR: 1.78; 95% CI: 1.26-2.53; p < 0.001). The risk of perioperative stroke was significantly increased in patients with preoperative hyperglycemia (OR: 2.51; 95% CI: 1.66-3.9; p < 0.001) in the propensity score matched cohort. Preoperative hyperglycemia was associated with the outcome for all the subgroups except for patients undergoing neurosurgery. CONCLUSION Preoperative hyperglycemia is associated with an elevated risk of perioperative stroke in patients with type 2 DM undergoing non-cardiovascular surgery. The effect could be eliminated for patients undergoing neurosurgery, during which specific risk factors should be considered.

Abstract
Background: More than four million people die each year in the month following surgery, and many more experience complications such as acute kidney injury. Some of these outcomes may be prevented through early identification of at-risk patients and through intraoperative risk mitigation. Telemedicine has revolutionized the way at-risk patients are identified in critical care, but intraoperative telemedicine services are not widely used in anesthesiology. Clinicians in telemedicine settings may assist with risk stratification and brainstorm risk mitigation strategies while clinicians in the operating room are busy performing other patient care tasks. Machine learning tools may help clinicians in telemedicine settings leverage the abundant electronic health data available in the perioperative period. The primary hypothesis for this study is that anesthesiology clinicians can predict postoperative complications more accurately with machine learning assistance than without machine learning assistance. Methods: This investigation is a sub-study nested within the TECTONICS randomized clinical trial (NCT03923699). As part of TECTONICS, study team members who are anesthesiology clinicians working in a telemedicine setting are currently reviewing ongoing surgical cases and documenting how likely they feel the patient is to experience 30-day in-hospital death or acute kidney injury. For patients who are included in this sub-study, these case reviews will be randomized to be performed with access to a display showing machine learning predictions for the postoperative complications or without access to the display. The accuracy of the predictions will be compared across these two groups. Conclusion: Successful completion of this study will help define the role of machine learning not only for intraoperative telemedicine, but for other risk assessment tasks before, during, and after surgery. Registration: ORACLE is registered on ClinicalTrials.gov: NCT05042804; registered September 13, 2021.

Elevated hemoglobin A1c level and bariatric surgery complications. Surg Endosc 2022; 36:6915-6923. [PMID: 35075523 DOI: 10.1007/s00464-022-09030-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Accepted: 01/03/2022] [Indexed: 10/19/2022]
Abstract
INTRODUCTION In cardiac and orthopedic surgery, elevated glycosylated hemoglobin (HbA1c) is a modifiable risk factor for postoperative complications. However, in bariatric surgery, there is insufficient evidence to assess the effectiveness of preoperative HbA1c assessment and its association with postoperative complications. The objective of this study was to assess the impact of HbA1c on early postoperative outcomes in bariatric surgery patients. METHODS Patients who underwent laparoscopic sleeve gastrectomy and laparoscopic Roux-En-Y Gastric Bypass between 2017 and 2018 were selected for a retrospective review from the metabolic and bariatric surgery accreditation and quality improvement program (MBSAQIP) database. The study population of 118,742 patients was analyzed for our primary outcome which was defined as a composite of any postoperative complications occurring within 30 days. Two groups were defined by HbA1c cutoff: comparison point A (≤ 8% vs > 8%) and comparison point B (≤ 10% vs > 10%). Procedure-related complications were also examined on subgroup analysis. Propensity score matching (PSM) was used with one-to-one matching. The complication rates before and after PSM were calculated and assessed by Fisher's exact test and conditional logistic regression, respectively. RESULTS After PSM, demographic and clinical characteristics were all balanced and elevated HbA1C was not associated with worse outcomes. After adjusting for underlying comorbidities, there was no statistically significant difference seen in the composite outcome for comparison point A HbA1C ≤ 8 and HbA1C > 8 (p = 0.22). For comparison point B, patients with HbA1C ≤ 10 had more composite complications compared to patients with HbA1C > 10 (p < 0.001). Also, on subgroup analysis after PSM for procedure-specific complications, patients above the cutoff threshold of 8 did not have worsened composite outcomes (p = 0.58 and 0.89 for sleeve and bypass, respectively). Again, at cutoff threshold of 10, patients in HbA1C ≤ 10 had more composite complications (p = 0.001 and 0.007 for sleeve and bypass, respectively). CONCLUSION In this study of bariatric patients, elevated HbA1c > 8% or 10% was not associated with increased postoperative complications. HbA1c lower than 10% was associated with some types of adverse outcomes in this bariatric dataset. More studies are needed to investigate these findings further. A high HbA1c alone may not disqualify a patient from proceeding with bariatric surgery.

Association of Preoperative Glycosylated Hemoglobin Level with 30-Day Outcomes Following Laparoscopic Roux-en-Y Gastric Bypass: an Analysis of the ACS-MBSAQIP Database. Obes Surg 2022; 32:3611-3618. [PMID: 36028650 DOI: 10.1007/s11695-022-06243-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 08/15/2022] [Accepted: 08/17/2022] [Indexed: 11/30/2022]
Abstract
PURPOSE Elevated glycosylated hemoglobin (HbA1c) levels have been associated with increased morbidity and mortality following several cardiac, colorectal, orthopedic, and vascular surgery operations. The purpose of this study was to determine if there is a HgA1c cut-point that can be used in patients undergoing laparoscopic Roux-en-Y gastric bypass to decrease the risk of 30-day wound events and additional 30-day morbidity and mortality. MATERIALS AND METHODS All patients undergoing first-time, elective Roux-en-Y gastric bypass in 2017 and 2018 with a diagnosis of diabetes mellitus (DM) and a preoperative HbA1c level were identified within the American College of Surgeons Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (ACS-MBSAQIP) database. The association of preoperative HbA1c levels with 30-day morbidity and mortality was investigated. RESULTS A total of 13,806 patients met inclusion criteria. Two natural HbA1c inflection points for composite wound events, including superficial, deep, and organ space surgical site infections (SSI) and wound dehiscence, were found. A HbA1c level of ≤ 6.5% was associated with a decreased odds of experiencing the composite 30-day wound event outcome while a HbA1c level of > 8.6% was associated with an increased odds of experiencing the composite 30-day wound event outcome. The differences in the incidence of the 30-day composite wound event outcomes were driven primarily by superficial and organ space SSI, including anastomotic leaks. CONCLUSION Patients with DM being evaluated for RYGB surgery with a HbA1c level > 8.6% are at an increased risk for 30-day wound events, including superficial and organ space SSI.

Abstract
BACKGROUND Prevailing insulin regimens for glycemic control in hospitalized patients have changed over time. We aimed to determine whether the current basal-bolus insulin (BBI) regimen is superior to the previous insulin regimen, mainly comprising split-mixed insulin therapy. METHODS This was a single tertiary center, retrospective observational study that included non-critically ill patients with type 2 diabetes mellitus who were treated with split-mixed insulin regimens from 2004 to 2007 (period 1) and with BBI from 2008 to 2018 (period 2). Patients from each period were analyzed after propensity score matching. The mean difference in glucose levels and the achievement of fasting and preprandial glycemic targets by day 6 of admission were assessed. The total daily insulin dose, incidence of hypoglycemia, and length of hospital stay were also evaluated. RESULTS Among 244 patients from each period, both fasting glucose (estimated mean±standard error, 147.4±3.1 mg/dL vs. 129.4±3.2 mg/dL, P<0.001, day 6) and preprandial glucose (177.7±2.8 mg/dL vs. 152.8±2.8 mg/dL, P<0.001, day 6) were lower in period 2 than in period 1. By day 6 of hospital admission, 42.6% and 67.2% of patients achieved a preprandial glycemic target of <140 mg/dL in periods 1 and 2, respectively (relative risk, 2.00; 95% confidence interval, 1.54 to 2.59), without an increased incidence of hypoglycemia. Length of stay was shorter in period 2 (10.23±0.26 days vs. 8.70±0.26 days, P<0.001). CONCLUSION BBI improved glycemic control in a more efficacious manner than a split-mixed insulin regimen without increasing the risk of hypoglycemia in a hospital setting.

[PMID: 35278194 PMCID: PMC8991233 DOI: 10.1007/s13300-022-01241-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 02/23/2022] [Indexed: 11/14/2022] Open
Abstract
INTRODUCTION In general surgery, it has been shown that poor peri-operative diabetes control, as measured by glycated haemoglobin (HbA1c), is associated with adverse post-operative outcomes. National data for the UK suggest that the post-operative complication rate for cataract surgery is 2.8%. It is unknown whether people with diabetes who undergo cataract surgery are also at increased risk. METHODS This single-centre retrospective study looked at the association of peri-operative HbA1c and estimated glomerular filtration rate (eGFR) with the risk of post-operative complications in people undergoing phacoemulsification and intraocular lens implantation under local anaesthesia during 2016. RESULTS 4401 individuals had cataract surgery. Of these, 34.6% (1525) had diabetes. Of those with diabetes, 114 (7.5%) developed a post-operative ophthalmological complication (as defined by the Royal College of Ophthalmologists) necessitating at least one eye clinic appointment. Mean HbA1c did not differ between those who did and those who did not develop complications (52 vs 50 mmol/mol, p = 0.12). After adjustment, HbA1c was not a significant risk (OR 1.00; 95% CI: 0.99-1.05; p = 0.85). However, eGFR had a small but statistically significant effect on outcome (OR 0.99; 95% CI: 0.98-1.00; p = 0.02). CONCLUSIONS This study has shown that more people who undergo cataract surgery have diabetes than previously reported. Also, people with diabetes are at higher risk of developing complications than previously reported. HbA1c concentration was not a factor in these adverse post-operative outcomes. However, eGFR was a predictor of risk. More focus should be placed on pre-operatively optimising co-morbidities than diabetes control in those undergoing cataract surgery.

Prehabilitation, enhanced recovery after surgery, or both? A narrative review. Br J Anaesth 2022; 128:434-448.

Abstract
This narrative review presents a biological rationale and evidence to describe how the preoperative condition of the patient contributes to postoperative morbidity. Any preoperative condition that prevents a patient from tolerating the physiological stress of surgery (e.g. poor cardiopulmonary reserve, sarcopaenia), impairs the stress response (e.g. malnutrition, frailty), and/or augments the catabolic response to stress (e.g. insulin resistance) is a risk factor for poor surgical outcomes. Prehabilitation interventions that include exercise, nutrition, and psychosocial components can be applied before surgery to strengthen physiological reserve and enhance functional capacity, which, in turn, supports recovery through attaining surgical resilience. Prehabilitation complements Enhanced Recovery After Surgery (ERAS) care to achieve optimal patient outcomes because recovery is not a passive process and it begins preoperatively.

Abstract
PURPOSE OF REVIEW Persons with diabetes are more likely to require orthopedic surgery and are at an increased risk of developing postoperative complications. Recognizing the impact of diabetes on musculoskeletal health provides an opportunity to educate healthcare professionals in standardizing the perioperative approach of persons with diabetes. RECENT FINDINGS Elevated hemoglobin A1C, fructosamine, and blood glucose levels have been associated with increased risk for complications in the orthopedic population. These risks can be mitigated by the early identification and optimization of these patients in the perioperative period. Intraoperative and postoperative glycemic management should support efforts to maintain glucose at safe levels while avoiding hyperglycemia and hypoglycemia. This paper considers factors surrounding diabetes care in the orthopedic surgical patient. Perioperative care discussed includes optimization, hospitalization to discharge, and special considerations such as steroids and diabetes wearable technology. Hospitals should consider these strategies towards enhancing the care of persons with diabetes requiring musculoskeletal care.

Abstract
INTRODUCTION Evidence-based preoperative, intraoperative and postoperative glycemic management may reduce poor surgical outcomes. Previous studies suggest that quality gaps in perioperative glycemic management may be common. RESEARCH DESIGN AND METHODS This retrospective cohort study used administrative health and laboratory data from a single center to estimate quality gaps in perioperative glycemic management in patients with and without diabetes between April 2019 and March 2020. We examined the proportion of patients with preoperative hemoglobin A1c (HbA1c) measurement, postoperative point-of-care testing (POCT) for glucose, hyperglycemia, and basal bolus insulin regimens. We compared the median length of stay (LOS) in patients with and without postoperative hyperglycemia, adjusted for age and sex. RESULTS There were 6576 patients in our cohort; 1165 (17.8%) had diabetes. Most patients with diabetes had an HbA1c measured prior to surgery (n=697, 59.8%). Postoperatively, 16.9% of patients with diabetes had no POCT monitoring (n=197) and 65.7% had hyperglycemia (n=636). Only 35.9% of patients who received insulin had a basal bolus insulin regimen (n=229). Patients with diabetes who had postoperative hyperglycemia had a longer median LOS compared with those who did not have postoperative hyperglycemia (8.4 days (95% CI 7.5 to 9.4) and 6.7 days (95% CI 6.3 to 7.1), respectively). In patients without diabetes, median LOS was 7.4 days (95% CI 4.4 to 10.4) for those with hyperglycemia and 5.2 days (95% CI 5.1 to 5.4) for those with in-target glucose. CONCLUSIONS Quality gaps in perioperative glycemic management include measurement of blood glucose after surgery and treatment of postoperative hyperglycemia. These gaps may contribute to longer LOS.

Abstract
BACKGROUND The hyperglycaemic effect of dexamethasone in diabetic and nondiabetic patients in the peri-operative period is unknown. OBJECTIVE To assess the effect of a single dose of intra-operative dexamethasone on peri-operative blood glucose. DESIGN Multicentre, stratified, randomised trial. SETTING University hospitals in Australia and Hong Kong. PATIENTS A total of 302 adults scheduled for elective, noncardiac and nonobstetric surgical procedures under general anaesthesia, stratified by diabetes mellitus status, were randomised to receive placebo, 4 or 8 mg dexamethasone administered intravenously after induction of anaesthesia. MAIN OUTCOME MEASURES Maximum blood glucose within 24 h of surgery, and the interaction between glycated haemoglobin (HbA1c) and dexamethasone were the primary and secondary outcomes. RESULTS The median [IQR] baseline blood glucose in the nondiabetes stratum in the placebo (n=81), 4 mg (n=81) and 8 mg dexamethasone (n=77) trial arms were respectively 5.3 [4.6 to 5.8], 5.0 [4.7 to 5.4] and 5.0 [4.2 to 5.9] mmol l-1. In the diabetes stratum these values were 6.6 [6.0 to 8.3]; (n=22), 6.1 [5.5 to 10.4]; (n=22) and 6.7 [5.6 to 8.3]; (n=19) mmol l-1. The median [IQR] maximum peri-operative blood glucose values in the nondiabetes stratum were 6.0 [5.3 to 6.8], 6.3 [5.5 to 7.3] and 6.3 [5.8 to 7.4] mmol l-1 in the control, dexamethasone 4 mg and dexamethasone 8 mg arms, respectively. In the diabetes stratum these values were 10.3 [8.1 to 12.4], 12.6 [10.3 to 18.3] and 13.6 [11.2 to 20.1] mmol l-1. There was a significant interaction between pre-operative HbA1c value and 8 mg dexamethasone: every 1% increment in HbA1c produced a 4.0 mmol l-1 elevation in maximal peri-operative glucose concentration. CONCLUSION Dexamethasone 4 mg or 8 mg did not induce greater hyperglycaemia compared with placebo for nondiabetic and well controlled diabetic patients. Maximal peri-operative blood glucose concentrations in patients with diabetes were related to baseline HbA1c values in a concentration-dependent fashion after 8 mg of dexamethasone.

Perioperative challenges in management of diabetic patients undergoing non-cardiac surgery. World J Diabetes 2021; 12:1255-1266.

Abstract
Prediabetes and diabetes are important disease processes which have several perioperative implications. About one third of the United States population is considered to have prediabetes. The prevalence in surgical patients is even higher. This is due to the associated micro and macrovascular complications of diabetes that result in the need for subsequent surgical procedures. A careful preoperative evaluation of diabetic patients and patients at risk for prediabetes is essential to reduce perioperative mortality and morbidity. This preoperative evaluation involves an optimization of preoperative comorbidities. It also includes optimization of antidiabetic medication regimens, as the avoidance of unintentional hypoglycemic and hyperglycemic episodes during the perioperative period is crucial. The focus of the perioperative management is to ensure euglycemia and thus improve postoperative outcomes. Therefore, prolonged preoperative fasting should be avoided and close monitoring of blood glucose should be initiated and continued throughout surgery. This can be accomplished with either analysis in blood gas samples, venous phlebotomy or point-of-care testing. Although capillary and arterial whole blood glucose do not meet standard guidelines for glucose testing, they can still be used to guide insulin dosing in the operating room. Intraoperative glycemic control goals may vary slightly in different protocols but overall the guidelines suggest a glucose range in the operating room should be between 140 mg/dL to 180 mg/dL. When hyperglycemia is detected in the operating room, blood glucose management may be initiated with subcutaneous rapid-acting insulin, with intravenous infusion or boluses of regular insulin. Fluid and electrolyte management are other perioperative challenges. Notably diabetic ketoacidosis and hyperglycemic hyperosmolar nonketotic state are the two most serious acute metabolic complications of diabetes that must be recognized early and treated.

Abstract
INTRODUCTION Pre-operative hemoglobin (Hb) A1c levels ≥ 8% can lead to increased post-operative complications. In bariatric surgery patients, attaining a pre-operative HbA1c < 8% can be a challenge. The purpose of this study was to identify the association of pre-operative HbA1c on post-operative outcomes in bariatric surgery patients. MATERIAL AND METHODS A retrospective chart review was conducted on diabetic patients (HbA1c ≥ 6.5%) who underwent primary bariatric surgery at a single institution between the years 2013 and 2019. Patients were divided into two groups based on their pre-operative HbA1c levels of < 8% and ≥ 8%. Univariate analyses were performed to determine an association between pre-operative HbA1c levels and post-operative outcomes. RESULTS There were 351 primary diabetic bariatric surgery patients, 270 HbA1c <8%, and 81 HbA1c ≥ 8%. Procedure selection was significantly different between the HbA1c < 8% and HbA1c ≥ 8% group (49.3% sleeve, 50.4% bypass and 0.4% band versus 43.2% sleeve, 53.1% bypass and 3.7% band respectively, P < 0.04). There was no statistically significant difference in any 30-day post-operative outcome between the two groups. Post-operative HbA1c was significantly less in the HbA1c < 8% group at 3-6 month (6.0% ± 0.9 versus 7.4% ± 1.4, P <0.001) and 6-12 month (6.0% ± 1.1 versus 7.2% ± 1.4, P <0.001) follow-up. CONCLUSIONS This study demonstrated no difference in post-operative outcomes of primary bariatric surgery patients based on a HbA1c cut-off of 8%. This highlights that bariatric surgery can be considered and safely performed in patients with a pre-operative HbA1c ≥ 8%.

Abstract
Study objective: Assess for a relationship between immediate preoperative glucose concentrations and postoperative complications. Design: Retrospective cohort study. Setting: Single large, tertiary care academic medical center. Patients: A five-year registry of all patients at our hospital who had a glucose concentration (plasma, serum, or venous/capillary/arterial whole blood) measured up to 6 h prior to a non-emergent surgery. Interventions: The glucose registry was cross-referenced with a database from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). We applied an outcomes review to the subset of patients for whom we had data from both registries (n = 1774). Measurements: Preoperative glucose concentration in the full population as well as the subgroups of patients with or without diabetes were correlated with adverse postsurgical outcomes using 1) univariable analysis and 2) full multivariable analysis correcting for 27 clinical factors available from the ACS NSQIP database. Logistic regression analysis was performed using glucose level either as a continuous variable or as a categorical variable according to the following classifications: mild (≥140 mg/dL; ≥7.8 mmol/L), moderate (≥180 mg/dL; ≥10 mmol/L), or severe (≥250 mg/dL; ≥13.9 mmol/L) hyperglycemia. A third analysis was performed correcting for 7 clinically important factors (age, BMI, predicted duration of procedure, sex, CKD stage, hypoalbuminemia, and diabetic status) identified by anesthesiologists and surgeons as immediately available and important for decision making. Main results: Univariable analysis of all patients and the subgroups of patients without diabetes or with diabetes showed that immediate preoperative mild or moderate hyperglycemia correlates with postoperative complications. Statistical significance was lost in most groups using full multivariable analysis, but not when correcting for the 7 factors available immediately preoperatively. However, for all patients with diabetes, moderate hyperglycemia (≥180 mg/dL; ≥10 mmol/L) continued to significantly correlate with complications even in the full multivariable analysis [odds ratio (OR) 1.79; 95% Confidence Intervals (CI) 1.10, 2.92], and with readmission/reoperation within 30 days [OR 1.93; 95% CI 1.18, 3.13]. Conclusions: Preoperative hyperglycemia within 6 h of surgery is a marker of adverse postoperative outcomes. Among patients with diabetes in our study, a preoperative glucose level ≥ 180 mg/dL (≥10 mmol/L) independently correlates with risk of postoperative complications and readmission/reoperation. These results should encourage future work to determine whether addressing immediate preoperative hyperglycemia can improve complication rates, or simply serves as a marker of higher risk.

Abstract
Patients with diabetes who undergo a surgical intervention have an increased risk of metabolic derailment, anesthesiological complications, postoperative infections and cardiovascular events. The treatment of diabetes mellitus is subject to a continuous further development due to pharmaceutical and technical innovations. This article presents the implications of the current concepts of diabetes treatment for perioperative medicine, particularly the changes due to new oral antidiabetic agents and insulin pump treatment. Some of the currently available guidelines are discussed with respect to the care of diabetes patients in childhood and adulthood in connection with an operation. Finally, possible perspectives in the field of monitoring and treatment of diabetes patients are discussed.

Investigating the effect of an education program on diabetes and lipid lowering medication usage following coronary artery bypass graft surgery. Intern Med J 2021; 52:1354-1365. [PMID: 34033208 DOI: 10.1111/imj.15393] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Revised: 04/14/2021] [Accepted: 05/20/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Guidelines advocate multifactorial cardiovascular risk management in patients with diabetes and atherosclerotic cardiovascular disease. In hospitalised patients with diabetes following coronary artery bypass graft (CABG) we evaluated the impacts of decision-support algorithms for optimising glycaemia and lipid-lowering. We also assessed the safety of initiating sodium-glucose cotransporter 2 (SGLT2) inhibitors near time of hospital discharge. METHODS This was a single-site, pre- and post-intervention analysis of glucose and lipid management in consecutive hospitalised patients with diabetes undergoing CABG surgery. The intervention involved education and decision-support algorithms designed by a multidisciplinary committee to guide cardiac surgery unit clinicians. RESULTS A total of 200 patients were included in the study. The pre- and post-intervention groups had similar baseline characteristics (HbA1c 7.9 ± 1.9% versus 8.1 ± 1.8%). Of 4092 blood glucose measurements the incidence of levels between 5 to 10 mmol/L was not different post-intervention (55.5% versus 57.0%, p = 0.441). Fewer endocrinology consultations occurred (59.0% versus 45.0%, p = 0.048) and rates of hypoglycaemia remained low. High-intensity statin was prescribed in >90% pre- and post-intervention although non-statin lipid-lowering agents remained <10% despite patients not achieving LDL-C targets. No 30-day readmissions for diabetic ketoacidosis occurred in patients prescribed SGLT2 inhibitors. CONCLUSION The intervention did not improve inpatient glycaemia or increase non-statin lipid-lowering prescriptions in patients with diabetes following CABG surgery but did reduce reliance on specialty input. Initiation of SGLT2 inhibitor therapy near time of hospital discharge was not associated with safety concerns. Alternative interventions or strategies are required to optimise glycaemia and non-statin lipid-lowering therapy prescribing in this setting. This article is protected by copyright.

Abstract
OBJECTIVES The goal of this quality initiative was to develop consensus standards for glycemic management of patients with diabetes who undergo surgical procedures in Canada. METHODS A modified Delphi method was used to gather broad stakeholder input and arrive at a consensus for perioperative/periprocedure diabetes management. RESULTS Glycemic management standards were developed for the following categories: Organization of Care; Preoperative Assessment; Immediate Preoperative and Intraoperative; Postanesthesia Care Unit or Recovery Room; Postoperative Period; and Transition to Outpatient Care. CONCLUSIONS It is anticipated these standards will serve as a basis to develop clinical tools to support the recommendations.

Diabetes management during cardiac surgery in the UK: A survey. Diabet Med 2021; 38:e14388.

Abstract
AIM To determine current practice regarding the diabetes management of people undergoing cardiac surgery in the UK. METHODS We conducted an online survey of UK cardiothoracic surgeons. All cardiothoracic surgeons listed in the Society of Cardiothoracic Surgery membership directory were invited to participate. The survey, compiled using SurveyMonkey software, comprised 15 closed and open-ended questions about the management of people with diabetes pre- and peri-operatively. RESULTS Sixty-two cardiothoracic surgeons from all 33 UK cardiac centres completed the survey. Of these, 44% responded that they routinely measure HbA1c preoperatively for all patients, 19% had an HbA1c threshold above which they would not operate and 21% currently undertake a point-of-care HbA1c measurement during the cardiothoracic outpatient visit. A total of 74% of respondents reported that it was 'easy' or 'very easy' to obtain a diabetes team review; diabetes nurse specialists were the members of the diabetes team working most closely with cardiac surgeons. Up to a third of the surgeons did not provide physical activity recommendations prior to admission and over 80% did not have a different preoperative or surgical diabetes protocol. Inconsistency in the responses within centres suggests that differences in practice may depend on individual surgeons rather than local policy. CONCLUSIONS The study demonstrates there is only limited peri-operative management of diabetes in people undergoing cardiac surgery in the UK. There is an opportunity for greater involvement of the diabetes specialist team both before and during admission for surgery to improve outcomes. (Trial registration: ISRCTN10170306).

Abstract
OBJECTIVES Poor control of diabetes mellitus is a known predictor of perioperative and postoperative complications. No literature to date has established a hemoglobin A1c (HbA1c) cutoff for risk stratification in the urogynecology population. We sought to identify an HbA1c threshold predictive of increased risk for perioperative and postoperative complications after pelvic reconstructive surgery. METHODS This multicenter retrospective cohort study involving 10 geographically diverse U.S. female pelvic medicine and reconstructive surgery programs identified women with diabetes who underwent prolapse and/or stress urinary incontinence surgery from September 1, 2013, to August 31, 2018. We collected information on demographics, preoperative HbA1c levels, surgery type, complications, and outcomes. Sensitivity analyses identified thresholds of complications stratified by HbA1c. Multivariate logistic regression further evaluated the association between HbA1c and complications after adjustments. RESULTS Eight hundred seven charts were identified. In this diabetic cohort, the rate of overall complications was 44.1%, and severe complications were 14.9%. Patients with an AM HbA1c value of 8% or greater (reference HbA1c, <8%) had an increased rate of both severe (27.1% vs 12.8%, P < 0.001) and overall complications (57.6% vs 41.8%, P = 0.002) that persisted after multivariate logistic regression (odds ratio, 2.618; 95% confidence interval, 1.560-4.393 and odds ratio, 1.931; 95% confidence interval, 1.264-2.949, respectively). Mesh complications occurred in 4.6% of sacrocolpopexies and 1.7% of slings. The average HbA1c in those with mesh exposures was 7.5%. CONCLUSIONS Preoperative HbA1c of 8% or higher was associated with a 2- to 3-fold increased risk of overall and severe complications in diabetic patients undergoing pelvic reconstructive surgery that persisted after adjustments.

Abstract
BACKGROUND Even though observational studies have suggested that poor preoperative diabetes control increases risk after major abdominal surgery, it is unclear whether this effect is seen in metabolic surgery patients. OBJECTIVES To determine whether poor preoperative diabetes control is associated with worse outcomes in patients with obesity and diabetes undergoing metabolic surgery. SETTING Metabolic and Bariatric Surgery Quality Improvement Project (MBSAQIP) database. METHODS Using the MBSAQIP 2017 and 2018 database and preoperative glycated hemoglobin (HbA1C) as a diabetes control surrogate, we examined the association between diabetes control and major outcomes of primary laparoscopic sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) in patients with diabetes and obesity. Multivariate logistic regression modeling examined five 30-day postoperative outcomes: composite serious complications (composite of 10 adverse events), composite infection (composite of 7 infectious complications), length of stay >5 days, reoperation, and readmission. Models were adjusted for multiple covariates. RESULTS In total, 26,674 patients with HbA1C data available within 30 days before metabolic surgery were included in the primary analysis and 35,884 patients with HbA1C data within 90 days before surgery were included in the sensitivity analysis. The mean body mass index (BMI) and preoperative HbA1C were 45.6 ± 8.2 kg/m2 and 8.2 ± 2.7%, respectively. The incidence of 30-day postoperative infections and serious complications were 1.62% and 1.35%, respectively. Neither primary analysis nor sensitivity analysis demonstrated any association between higher HbA1C and worsening of 5 primary outcomes of interest. The odds ratio of an overall effect for SG was 1.01 (95% CI .98-1.03; P = .58) and for RYGB was .99 (95% CI .96-1.02; P = .41). CONCLUSION Suboptimal preoperative diabetes control is not associated with increased adverse events and should not delay metabolic surgery, as metabolic surgery is generally a safe procedure and intrinsically improves diabetes control.

Abstract
STUDY OBJECTIVE To evaluate whether diabetes diagnosis and level of diabetes control as reflected by higher preoperative glycosylated hemoglobin (HbA1c) levels are associated with increased complication rates after hysterectomy and to identify a threshold of preoperative HbA1c level past which we should consider delaying surgery owing to increased risk of complications. DESIGN Retrospective cohort study. SETTING Hospitals in the Michigan Surgical Quality Collaborative between June 4, 2012, and October 17, 2017. PATIENTS Women with and without a diabetes diagnosis. INTERVENTIONS Hysterectomy. MEASUREMENTS AND MAIN RESULTS Data on demographics, preoperative HbA1c values, surgical approach, composite postoperative complications, readmissions, emergency department visits, and reoperations were abstracted. The risk of a postoperative complication when diabetes was stratified by preoperative HbA1c level was evaluated in a sensitivity analysis, and independent associations were identified in a mixed, multivariate logistic regression model. We identified 41 286 hysterectomies performed at 70 hospitals to be included for analysis. The sensitivity analysis identified 4 groups of risk for postoperative complications: group 1: no diabetes diagnosis and no HbA1c value; group 2: no diabetes diagnosis, with HbA1c levels between 4% and 6.5%; group 3: diabetes diagnosis and no HbA1c value or HbA1c levels <9%; and group 4: diabetes diagnosis with HbA1c levels ≥9%. In the adjusted model, there were significant 32% and 34% increased odds of postoperative complications for groups 2 and 3, respectively, compared with group 1. There were more than 2-fold increased odds of complications for women with diabetes and a preoperative HbA1c level ≥9% (group 4) compared with the women in group 1. Diabetes diagnosis with preoperative HbA1c levels ≥9% had increased odds of complications compared with diabetes diagnosis with preoperative HbA1c levels <9%. Patients with well-controlled diabetes seemed to have increased odds of complications with laparoscopic surgery. CONCLUSION Diabetes diagnosis and measurement of preoperative HbA1c levels provide risk stratification for postoperative complications after hysterectomy, with the highest observed effect among patients with diabetes with a preoperative HbA1c level ≥9%.

Motivational Interviewing and Glycemic Control in Adolescents With Poorly Controlled Type 1 Diabetes: A Randomized Controlled Pilot Trial. Front Endocrinol (Lausanne) 2021; 12:639507.

Abstract
A multicenter randomized controlled pilot trial investigated whether motivational interviewing (MI) by diabetes physicians improves glycemic control and variability in the context of follow-up for adolescent patients with poorly controlled type 1 diabetes. Patients (n = 47) aged 12 to 15.9 years who showed poor glycemic control (HbA1c >75 mmol/mol/9.0%) were randomized to standard education (SE) only or MI+SE, with study physicians randomized to employ MI+SE (N = 24 patients) or SE only (N = 23). For one year of follow-up, the main outcome measurements were obtained at three-month visits (HbA1c) or six-monthly: time in range (TIR) and glycemic variability (CV). Mean adjusted 12-month change in HbA1c was similar between the MI+SE and SE-only group (-3.6 vs. -1.0 mmol/mol), and no inter-group differences were visible in the mean adjusted 12-month change in TIR (-0.8 vs. 2.6%; P = 0.53) or CV (-0.5 vs. -6.2; P = 0.26). However, the order of entering the study correlated significantly with the 12-month change in HbA1c in the MI+SE group (r = -0.5; P = 0.006) and not in the SE-only group (r = 0.2; P = 0.4). No link was evident between MI and changes in quality of life. The authors conclude that MI's short-term use by diabetes physicians managing adolescents with poorly controlled type 1 diabetes was not superior to SE alone; however, improved skills in applying the MI method at the outpatient clinic may produce greater benefits in glycemic control.

Abstract
INTRODUCTION The impact of diabetes mellitus (DM) on outcomes of lower extremity revascularization (LER) for peripheral artery disease (PAD) is uncertain. We characterized associations between DM and post-procedural outcomes in PAD patients undergoing LER. METHODS Adults undergoing surgical or endovascular LER were identified from the 2014 Nationwide Readmissions Database. DM was defined by ICD-9 diagnosis codes and sub-classified based on the presence or absence of complications (poor glycemic control or end-organ damage). Major adverse cardiovascular and limb events (MACLE) were defined as the composite of death, myocardial infarction, ischaemic stroke, or major limb amputation during the index hospitalization for LER. For survivors, all-cause 6-month hospital readmission was determined. RESULTS Among 39,441 patients with PAD hospitalized for LER, 50.8% had DM. The composite of MACLE after LER was not different in patients with and without DM after covariate adjustment, but patients with DM were more likely to require major limb amputation (5.5% vs. 3.2%, p < 0.001; adjusted odds ratio [aOR] 1.22, 95% CI 1.03-1.44) and hospital readmission (59.2% vs. 41.3%, p < 0.001; aOR 1.44, 95% CI 1.34-1.55). Of 20,039 patients with DM hospitalized for LER, 55.7% had DM with complications. These patients were more likely to have MACLE after LER (11.1% vs. 5.2%, p < 0.001; aOR 1.56 95% CI 1.28-1.89) and require hospital readmission (61.1% vs. 47.2%, p < 0.001; aOR 1.41 95% CI 1.27-1.57) than patients with uncomplicated DM. CONCLUSIONS DM is present in ≈50% of patients undergoing LER for PAD and is an independent risk factor for major limb amputation and 6-month hospital readmission.

Abstract
Evaluation of endocrine issues is a sometimes overlooked yet important component of the preoperative medical evaluation. Patients with diabetes, thyroid disease, and hypothalamic-pituitary-adrenal axis suppression are commonly encountered in the surgical setting and require unique consideration to optimize perioperative risk. For patients with diabetes, perioperative glycemic control has the strongest association with postsurgical outcomes. The preoperative evaluation should include recommendations for adjustment of insulin and noninsulin diabetic medications before surgery. Recommendations differ based on the type of diabetes, the type of insulin, and the patient's predisposition to hyperglycemia or hypoglycemia. Generally, patients with thyroid dysfunction can safely undergo operations unless they have untreated hyperthyroidism or severe hypothyroidism. Patients with known primary or secondary adrenal insufficiency require supplemental glucocorticoids to prevent adrenal crisis in the perioperative setting. Evidence supporting the use of high-dose supplemental corticosteroids for patients undergoing long-term glucocorticoid therapy is sparse. We discuss an approach to these patients based on the dose and duration of ongoing or recent corticosteroid therapy. As with other components of the preoperative medical evaluation, the primary objective is identification and assessment of the severity of endocrine issues before surgery so that the surgeons, anesthesiologists, and internal medicine professionals can optimize management accordingly.

Abstract
Type 2 Diabetes Mellitus (DM) is a chronic disease with high prevalence worldwide. Using glycated haemoglobin (HbA1c) as a surrogate for potential pre-DM and DM conditions, our primary objective was to determine the HbA1c epidemiology in non-cardiac elective surgical patients in Singapore. Our secondary aim was to identify risk factors associated with elevated HbA1c. We conducted a prospective, observational single-centre study in adult patients. HbA1c screening was performed. Patient demographics and comorbidities were recorded. Patients were divided into those with HbA1C ≤ 6.0% and HbA1C ≥ 6.1%. Regression analyses were performed to identify associated factors. Subgroup analysis was performed comparing patients with HbA1C ≥ 6.1% and HbA1C ≥ 8.0%. Of the 875 patients recruited, 182 (20.8%) had HbA1c ≥ 6.1%, of which 32 (3.7%) had HbA1c ≥ 8%. HbA1C ≥ 6.1% was associated with Indian ethnicity [1.07 (1.01–1.13), p = 0.023], BMI > 27.5 [1.07 (1.02–1.11), p = 0.002], higher preoperative random serum glucose [1.03 (1.02–1.04), p < 0.001], pre-existing diagnosis of DM [1.85 (1.75–1.96), p < 0.001] and prediabetes [1.44 (1.24–1.67), p < 0.001], and peripheral vascular disease [1.30 (1.10–1.54), p = 0.002]. HbA1c ≥ 8% had an additional association with age > 60 years [0.96 (0.93–0.99), p = 0.017]. The prevalence of elevated HbA1c is high among the surgical population. Targeted preoperative HbA1c screening for at-risk elective surgical patients reduces cost, allowing focused use of healthcare resources.

Abstract
OBJECTIVE To examine whether HbA1c, outpatient diabetes treatment regimen, demographics, and clinical characteristics are associated with mortality in hospitalized patients with diabetes and coronavirus disease 2019 (COVID-19). RESEARCH DESIGN AND METHODS This was a retrospective cohort analysis of patients with diabetes hospitalized with confirmed COVID-19 infection from 11 March to 7 May 2020 at a large academic medical center in New York City. Multivariate modeling was used to assess the independent association of HbA1c levels and outpatient diabetes treatment regimen with mortality, in addition to independent effects of demographic and clinical characteristics. RESULTS We included 1,126 hospitalized patients with diabetes and COVID-19 for analysis, among whom mean age was 68 years, 50% were male, 75% were Black, mean BMI was 30 kg/m2, 98% had type 2 diabetes, mean HbA1c was 7.5%, and 33.1% died. HbA1c levels were not associated with mortality in unadjusted or adjusted analyses, but an outpatient regimen with any insulin treatment was strongly predictive. Additionally, age, sex, and BMI interacted such that in all age categories, mortality was higher with increasing BMI in males compared with females. CONCLUSIONS In this large U.S. cohort of hospitalized patients with diabetes and COVID-19, insulin treatment, as a possible proxy for diabetes duration, and obesity rather than long-term glycemic control were predictive of mortality. Further investigation of underlying mechanisms of mortality and inpatient glycemic control is needed.

Abstract
People with diabetes occupy approximately 18% of all acute inpatient hospital beds in the UK, compared with 6.5% of the general population. For those undergoing surgery, having diabetes is known to be associated with increased harms, however harm is defined. For those undergoing elective surgery, there is a defined patient journey, starting with referral from primary care to surgical outpatients, then onto preoperative assessment clinic before being admitted for surgery, and then from recovery through to discharge home. Because of the multiple causes for possible harm, communication between members of the healthcare team at each stage of this journey and with the person with diabetes is essential.Recently, the National Confidential Enquiry into Patient Outcomes and Death has shown that the care of people with diabetes undergoing surgery needs to be improved, and they have made several recommendations that trusts should adopt to minimise the harms in this vulnerable population.
