Abstract
The American Diabetes Association (ADA), European Association for the Study of Diabetes (EASD), Joint British Diabetes Societies for Inpatient Care (JBDS), American Association of Clinical Endocrinology (AACE), and Diabetes Technology Society (DTS) convened a panel of internists and diabetologists to update the ADA consensus statement on hyperglycemic crises in adults with diabetes, published in 2001 and last updated in 2009. The objective of this consensus report is to provide up-to-date knowledge about the epidemiology, pathophysiology, clinical presentation, and recommendations for the diagnosis, treatment, and prevention of diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) in adults. A systematic examination of publications since 2009 informed new recommendations. The target audience is the full spectrum of diabetes health care professionals and individuals with diabetes.

Abstract
Background Diabetes mellitus remains a pressing global health issue, characterized by chronic metabolic dysfunction and the potential for life-threatening acute hyperglycemic emergencies. These emergencies, known as diabetic ketoacidosis and hyperosmolar hyperglycemic states, trigger a series of physiological disruptions. This article delves deeply into how the type and duration of diabetes mellitus affect the occurrence of hyperglycemic emergencies and mortality rates. Methods The study was conducted at the Institute of Internal Medicine, Rajiv Gandhi General Hospital, affiliated with Madras Medical College, spanning from July 2021 to December 2021. It encompassed both individuals newly diagnosed with diabetic ketoacidosis and patients already undergoing diabetic treatment who developed diabetic ketoacidosis and hyperosmolar hyperglycemic states. Results Within the study cohort of 110 patients, 37.27% were diagnosed with Type 1 diabetes mellitus, while 62.73% were classified as Type 2 diabetes mellitus patients. Among these individuals, 23.60% were newly diagnosed with diabetes, 22.70% had been diabetic for less than one year, 47.30% had a diabetic history of two to five years, and 6.40% had been diabetic for over six years. However, upon investigating the relationship between diabetes duration and mortality rate, no statistically significant findings were observed. Conclusion Hyperglycemic emergencies represent multifaceted clinical challenges influenced by the interplay of various factors, including the type and duration of the disease. By maintaining effective management of hyperglycemia from the outset and sustaining it throughout their lives, people with diabetes can improve their physical and mental health and reduce the likelihood of developing long-term complications that may negatively impact their overall well-being.

Abstract
OBJECTIVES To determine the incidence of bacteremia in patients with DKA. METHODS We conducted a cross-sectional study of patients aged 18 years and older with a principal diagnosis of DKA or hyperglycemic hyperosmotic syndrome (HHS) who presented to our community hospital between 2008 and 2020. Using medical records from initial visits, we retrospectively calculated the incidence of bacteremia. This was defined as the percentage of subjects with positive blood cultures except for those with contamination. RESULTS Among 114 patients with hyperglycemic emergency, two sets of blood cultures were collected in 45 of 83 patients with DKA (54%), and 22 of 31 patients with HHS (71%). The mean age of patients with DKA was 53.7 years (19.1) and 47% were male, while the mean age of patients with HHS was 71.9 years (14.9) and 65% were male. The incidences of bacteremia and blood culture positivity were not significantly different between patients with DKA and those with HHS (4.8% vs. 12.9%, P = 0.21 and 8.9% vs. 18.2%, P = 0.42, respectively). Urinary tract infection was the most common concomitant infection of bacteria, with E. coli as the main causative organism. CONCLUSION Blood cultures were collected in approximately half of the patients with DKA, despite a nonnegligible number of them testing positive in blood culture. Promoting awareness of the need for taking blood culture is imperative for the early detection and management of bacteremia in patients with DKA.

Int J Med Inform 2023; 174:105049.

Abstract
AIM To establish a prediction model and assess the risk factors for severe diabetic ketoacidosis (DKA) in adult patients during the ICU. INTRODUCTION With DKA hospitalization rates consistently increasing, in-hospital mortality has become a growing concern. METHODS DKA patients aged >18 years old in the US-based critical care database (Medical Information Mart for Intensive Care (MIMIC-IV)) were considered. Independent risk factors for in-hospital mortality were screened using extreme gradient boosting (XGBoost) and the Bayesian information criterion (BIC) optimal subset regression. One predictive model was developed using machine learning extreme gradient boosting (XGBoost), and the other one was a nomogram based on logistic regression to estimate risks of in-hospital mortality with severe DKA. Established models were assessed by using internal validation and external validation. The MIMIC-IV was split into training and testing samples in a 7:3 ratio. The eICU Collaborative Research Database and admissions data from the department of critical care medicine of the first affiliated hospital of Harbin medical university were used for independent validation. The discriminatory ability of the model was determined by illustrating a receiver operating curve (ROC) and calculating the C-index. Meanwhile, the calibration plot and Hosmer-Lemeshow goodness-of-fit test (HL test) was conducted to evaluate the performance of our new build model. Decision curve analysis (DCA) was performed to assess the clinical net benefit. Net Reclassification Improvement (NRI) was used to compare the predictive power of the two models. RESULTS A multivariable model that included acute physiology score III (APS III), the highest levels of blood plasma osmolality (osmolarity_max), minimum osmolarity (osmolarity_min)/osmolarity _max, vasopressor, and the highest levels of blood lactate was represented as the nomogram. The C- index of the nomogram model was 0.915 (95% CI: 0.966-0.864) in the training dataset and 0.971 (95% CI: 0.992-0.950) in the internal validation. The nomogram's sensitivity was well according to all data's HL test (P > 0.05). DCA showed that our model was clinically valuable. The XGB (extreme gradient boosting) model achieved an AUC (area under the curve) of 0.950 (95% CI, 0.920-0.980); however, the nomogram model made was more effective than XGB based on NRI. CONCLUSION The predictive XGB and nomogram models for predicting in-hospital patient deaths with DKA were effective. The forecast models can help clinical physicians promptly identify patients at high risk of DKA, prevent in-hospital deaths, and promptly intervene.

Abstract
BACKGROUND AND OBJECTIVES CKD imposes a significant burden on patients and health care providers, particularly upon reaching kidney failure when patients may require KRT. The Dapagliflozin and Prevention of Adverse Outcomes in CKD (DAPA-CKD) trial demonstrated that dapagliflozin, with standard therapy, reduced CKD progression and KRT requirement. The study objective was to estimate the cost-effectiveness of dapagliflozin for the treatment of CKD from payer perspectives in the United Kingdom, Germany, and Spain. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We constructed a lifetime Markov model to characterize outcomes in patients with CKD on the basis of the DAPA-CKD trial. Health states were defined by eGFR level and KRT type. Direct health care costs and utility values were sourced from published literature and the DAPA-CKD trial, respectively. Costs and benefits were discounted at 3.5% per annum in the United Kingdom and 3% in Germany and Spain. RESULTS In patients eligible for the DAPA-CKD trial, treatment with dapagliflozin was predicted to reduce rates of CKD progression, with patients predicted to spend 1.7 (95% credibility interval, 0.8 to 2.4) more years in the eGFR range 15-89 ml/min per 1.73 m2 versus standard therapy alone (12.1; 95% credibility interval, 8.9 to 14.1 versus 10.4; 95% credibility interval, 7.7 to 12.4 years). Life expectancy (undiscounted) was correspondingly predicted to increase by 1.7 (95% credibility interval, 0.7 to 2.5) years (15.5; 95% credibility interval, 11.1 to 18.2 versus 13.8; 95% credibility interval, 9.9 to 16.5 years). This in addition to reduced incidence of adverse clinical outcomes, including hospitalization for heart failure, resulted in modeled quality-adjusted life year (discounted) gains between 0.82 (95% credibility interval, 0.38 to 1.18) and 1.00 (95% credibility interval, 0.46 to 1.41). These gains translated to incremental cost-effectiveness ratios of $8280, $17,623, and $11,687 in the United Kingdom, Germany, and Spain, respectively, indicating cost-effectiveness at willingness-to-pay thresholds (United Kingdom: $27,510 per quality-adjusted life year; Germany and Spain: $35,503 per quality-adjusted life year). CONCLUSIONS In patients meeting the eligibility requirements for the DAPA-CKD trial, dapagliflozin is likely to be a cost-effective treatment within the UK, German, and Spanish health care systems. CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER Dapagliflozin and Prevention of Adverse Outcomes in CKD (DAPA-CKD), NCT03036150.

Abstract
INTRODUCTION Real-time continuous glucose monitoring (rt-CGM) involves the measurement and display of glucose concentrations, potentially improving glucose control among insulin-treated patients with type 2 diabetes (T2D). The present analysis aimed to conduct a cost-effectiveness analysis of rt-CGM versus self-monitoring of blood glucose (SMBG) based on a USA retrospective cohort study in insulin-treated people with T2D adapted to the UK. METHODS Long-term costs and clinical outcomes were estimated using the CORE Diabetes Model, with clinical input data sourced from a retrospective cohort study. Patients were assumed to have a baseline glycated hemoglobin (HbA1c) of 8.3%. Patients using rt-CGM were assumed to have a 0.56% reduction in HbA1c based on the mean difference between groups after 12 months of follow-up. Reduced fingerstick testing when using rt-CGM was associated with a quality of life (QoL) benefit. The analysis was performed over a lifetime time horizon from a National Health Service (NHS) perspective, including only direct costs from published data. Future costs and clinical outcomes were discounted at 3.5% per annum. Extensive sensitivity analyses were performed. RESULTS Projections showed that rt-CGM was associated with increased quality-adjusted life expectancy of 0.731 quality-adjusted life years (QALYs) and increased mean total lifetime costs of Great British pounds (GBP) 2694, and an incremental cost-effectiveness ratio of GBP 3684 per QALY compared with SMBG. Key drivers of outcomes included HbA1c reduction and reduced fingerstick testing QoL benefit. CONCLUSIONS Over patient lifetimes, rt-CGM was associated with improved clinical outcomes and is highly likely to be cost effective versus SMBG in people with T2D on insulin therapy in the UK.

Abstract
AIMS To assess the clinical characteristics and outcomes of patients hospitalized with DKA. METHODS We examined the hospital database for patients admitted with DKA to all government hospitals in Qatar over 6 years. RESULTS We evaluated a total of 1330 patients [(37.3 % with type 1 diabetes (T1DM) and 62.7 % with type 2 diabetes (T2DM)] with 1613 episodes of DKA. Patients with T2DM were older than those with T1DM [48.0 (38.0-60.0), 26.0 (21.0-31.0) years] while there was no difference in DKA severity and laboratory values on admission or time to resolution of DKA. Admission to the intensive care unit was higher (38.9 % vs. 26.6 %; P < 0.001) with a longer hospital stay [5 (2.0-9.0) vs. 2 (2.0-4.0) days, P < 0.001] and markedly higher mortality (7.4 % vs. 1 %; P < 0.001) in patients with T2DM compared to T1DM. On multivariable logistic regression analysis, significant predictors of mortality were older age (odds ratio, 1.11; 95 % CI, 1.07-1.15; P = 0.0001), and admission to the intensive care unit (odds ratio, 3.61; 95 % CI, 1.69-7.72;P = 0.001). CONCLUSION In this national cohort of patients hospitalized with DKA, those with T2DM had a 7-fold increase in inpatient mortality associated with older age and admission to the intensive care unit.

Materials and methods Individuals with type 1 diabetes hospitalized for DKA from January 2005 to March 2010 (first period [P1], n = 75) and from April 2010 to January 2017 (second period [P2], n = 97) were identified through a query of electronic medical records. Data were collected by reviewing medical records. Only the first hospitalization of each participant in each period was included. Results In P2, 44 patients (45.4%) were women, mean age was 26.2 ± 14.5 years, and 74 patients (76.3%) had a previous diagnosis of type 1 diabetes. Only 1 patient had glycated haemoglobin (HbA1c) below 64 mmol/mol (8.0%). Most patients (62.2%) had had a previous episode of DKA. In P1, non-adherence was the main cause of DKA (38.7%), followed by infection (24.0%). In P2, these rates were 34.0% and 24.7%, respectively; no statistical difference was observed between the two study periods (p = 0.790). Conclusion Over time, non-adherence remained the main precipitating factor of DKA, followed by infection, and no significant difference was observed between the two study periods. Elevated HbA1c, outside the therapeutic range, indicates suboptimal diabetes care and may explain, at least in part, poor adherence as a precipitating factor of decompensation. Health strategies, such as improved self-management of type 1 diabetes, may contribute to a future reduction in DKA episodes.

Abstract
This article summarises the Joint British Diabetes Societies for Inpatient Care guidelines on the management of ketoacidosis; available at https://abcd.care/resource/management-diabetic-ketoacidosis-dka-adults. The document explicitly states that when a person aged 16-18 is under the care of the paediatric team, then the paediatric guideline should be used, and if they are cared for by an adult team, then this guideline should be used. The guideline takes into account new evidence on the use of the previous version of this document, particularly the high prevalence of hypoglycaemia and hypokalaemia, and recommends that when the glucose concentration drops below 14 mmol/L, that de-escalating the insulin infusion rate from 0.1 to 0.05 units/kg/h should be considered. Furthermore, a section has been added to address the recognition that use of sodium glucose co-transporter 2 inhibitors is associated with an increased risk of euglycaemic ketoacidosis. The management of ketoacidosis in people with end-stage renal failure or on dialysis is also mentioned. Finally, the algorithms to illustrate the guideline have been updated.

Abstract
IMPORTANCE Standard diabetic ketoacidosis care in the US includes intravenous insulin treatment in the intensive care unit. Subcutaneous (SQ) insulin could decrease intensive care unit need, but the data are limited. OBJECTIVE To assess outcomes after implementation of an SQ insulin protocol for treating diabetic ketoacidosis. DESIGN, SETTING, AND PARTICIPANTS This cohort study is a retrospective evaluation of a prospectively implemented SQ insulin protocol. The study was conducted at an integrated health care system in Northern California. Participants included hospitalized patients with diabetic ketoacidosis at 21 hospitals between January 1, 2010, and December 31, 2019. The preimplementation phase was 2010 to 2015, and the postimplementation phase was 2017 to 2019. Data analysis was performed from October 2020 to January 2022. EXPOSURE An SQ insulin treatment protocol for diabetic ketoacidosis. MAIN OUTCOMES AND MEASURES Difference-in-differences evaluation of the need for intensive care, mortality, readmission, and length of stay at a single intervention site using an SQ insulin protocol from 2017 onward compared with 20 control hospitals using standard care. RESULTS A total of 7989 hospitalizations for diabetic ketoacidosis occurred, with 4739 (59.3%) occurring before and 3250 (40.7%) occurring after implementation. The overall mean (SD) age was 42.3 (17.7) years, with 4137 hospitalizations (51.8%) occurring among female patients. Before implementation, SQ insulin was the first insulin used in 40 intervention (13.4%) and 651 control (14.7%) hospitalizations. After implementation, 98 hospitalizations (80.3%) received SQ insulin first at the intervention site compared with 402 hospitalizations (12.8%) at control sites. The adjusted rate ratio for intensive care unit admission was 0.43 (95% CI, 0.33-0.56) at the intervention sites, a 57% reduction compared with control sites, and was 0.50 (95% CI, 0.25-0.99) for 30-day hospital readmission, a 50% reduction. There were no significant changes in hospital length of stay and rates of death. CONCLUSIONS AND RELEVANCE These findings suggest that a protocol based on SQ insulin for diabetic ketoacidosis treatment was associated with significant decreases in intensive care unit need and readmission, with no evidence of increases in adverse events.

Base excess measured at hospital admission is useful for predicting diabetic ketoacidosis severity and resolution time in adult patients. Diabetes Metab Syndr 2022; 16:102385. [PMID: 35026666 DOI: 10.1016/j.dsx.2021.102385] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Revised: 12/28/2021] [Accepted: 12/29/2021] [Indexed: 11/19/2022]
Abstract
BACKGROUND AND AIMS This study aimed to identify the biochemical factors measured at hospital admission that could predict diabetes ketoacidosis (DKA) resolution time in adult patients. MATERIALS AND METHODS This retrospective study included 79 patients >18 years of age. Multivariate analyses were performed to determine which variables might predict DKA resolution time. Biochemical parameters between the two DKA resolution time groups were compared. RESULTS Using multiple linear regression models, acidosis time was found to decrease by 29 h if the pH value increased by one unit, 0.64 h if the base excess (BE) value increased by 1 mmol, and 1.09 h if the bicarbonate (HCO3-) value increased by 1 mmol. The biochemical parameters that differed between the two groups were pH, HCO3-, and BE. Patients with delayed resolution of DKA had a blood pH of 7.1 (±0.18), HCO3- of 5.1 mmol (2.9-11.6 mmol), and BE of -21.5 mmol (-28.2 to -14.4 mmol) at hospital admission. CONCLUSIONS Lower pH, HCO3-, and BE values at hospital admission may predict longer DKA resolution times in adult patients. In addition, BE may predict DKA severity.

Abstract
AIM To systematically review the literature concerning the psychosocial factors associated with repeat diabetic ketoacidosis for people living with type 1 diabetes. METHODS PsycInfo, Web of Science, CINAHL, PubMed and ASSIA were searched according to a registered study protocol (PROSPERO CRD42020167381). Data were extracted into a coding spreadsheet, and findings were synthesised narratively. Included papers were also subject to a quality assessment. RESULTS The search yielded 548 unique articles, of which 22 met inclusion criteria for this review. There was considerable variance across studies with regard to design, quality and outcome measured. Nevertheless, there was relatively consistent evidence to suggest that repeat diabetic ketoacidosis in type 1 diabetes is associated with female gender, adolescent to young adult age range, lower socio-economic status and poor mental health. Some evidence was also observed for the role of ethnicity and, for children and young people at least, family, social and behavioural issues. However, this was limited by issues of methodological rigour and scant investigation. CONCLUSIONS The review identified four psychosocial factors that appear to play a key role in the cycle of repeat diabetic ketoacidosis. Individuals with these factors present may benefit from targeted support and interventions by specialist healthcare professionals. Knowledge and understanding in this area would be considerably enhanced via increased use of prospective study designs and greater consistency in the operationalisation of variables across studies.

Abstract
OBJECTIVE Diabetic ketoacidosis (DKA) is a life-threatening complication of both type 1 and type 2 diabetes. We aimed to assess population-based rates, trends and outcomes of patients with DKA. DESIGN AND METHODS This is a nationwide cohort study using hospital discharge claims data from 2010 to 2018 in Switzerland. Incidence rates and in-hospital outcomes of DKA were analyzed throughout lifetime for children (0-9 years), adolescents (10-19 years), and adults (20-29, 30-59, and 60-90 years). Analyses were stratified for type of diabetes mellitus and sex. RESULTS In total, 5,544 hospitalizations with DKA were identified, of whom 3,847 were seen in patients with type 1 diabetes and 1,697 in type 2 diabetes. Incidence rates of DKA among patients with type 1 diabetes were highest during adolescence with 17.67 (girls) and 13.87 (boys) events per 100,000 person-years (incidence rate difference [IRD]: -3.80 [95% CI, -5.59 to -2.02]) and decreased with age in both sexes thereafter. Incidence rates of DKA in patients with type 2 diabetes were low up to an age of 40 years and rose to 5.26 (females) and 6.82 (males) per 100,000 person-years in adults aged 60-90 years. Diabetic ketoacidosis was associated with relevant health-care burden independent of age, sex, or type of diabetes. The population-based incidence rate of DKA increased over time from 7.22 per 100,000 person-years in 2010 to 9.49 per 100,000 person-years in 2018. CONCLUSIONS In type 1 diabetes highest incidence rates of DKA hospitalizations were observed among adolescent females. In comparison, in patients with type 2 diabetes the risk for DKA steadily increased with age with higher rates in adult males. Over the 9 year study period, incidence rates of DKA were increasing irrespective of type of diabetes. DKA was associated with a high burden of disease reflected by high rates of intensive care unit admission, prolonged hospital stay and high mortality rates, especially in elderly.

Abstract
BACKGROUND For people with diabetes mellitus to achieve optimal glycaemic control, motivation to perform self-management is important. The research team wanted to determine whether or not psychological interventions are clinically effective and cost-effective in increasing self-management and improving glycaemic control. OBJECTIVES The first objective was to determine the clinical effectiveness of psychological interventions for people with type 1 diabetes mellitus and people with type 2 diabetes mellitus so that they have improved (1) glycated haemoglobin levels, (2) diabetes self-management and (3) quality of life, and fewer depressive symptoms. The second objective was to determine the cost-effectiveness of psychological interventions. DATA SOURCES The following databases were accessed (searches took place between 2003 and 2016): MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, PsycINFO, EMBASE, Cochrane Controlled Trials Register, Web of Science, and Dissertation Abstracts International. Diabetes conference abstracts, reference lists of included studies and Clinicaltrials.gov trial registry were also searched. REVIEW METHODS Systematic review, aggregate meta-analysis, network meta-analysis, individual patient data meta-analysis and cost-effectiveness modelling were all used. Risk of bias of randomised and non-randomised controlled trials was assessed using the Cochrane Handbook (Higgins JP, Altman DG, Gøtzsche PC, Jüni P, Moher D, Oxman AD, et al. The Cochrane Collaboration's tool for assessing risk of bias in randomised trials. BMJ 2011;343:d5928). DESIGN Systematic review, meta-analysis, cost-effectiveness analysis and patient and public consultation were all used. SETTING Settings in primary or secondary care were included. PARTICIPANTS Adolescents and children with type 1 diabetes mellitus and adults with types 1 and 2 diabetes mellitus were included. INTERVENTIONS The interventions used were psychological treatments, including and not restricted to cognitive-behavioural therapy, counselling, family therapy and psychotherapy. MAIN OUTCOME MEASURES Glycated haemoglobin levels, self-management behaviours, body mass index, blood pressure levels, depressive symptoms and quality of life were all used as outcome measures. RESULTS A total of 96 studies were included in the systematic review (n = 18,659 participants). In random-effects meta-analysis, data on glycated haemoglobin levels were available for seven studies conducted in adults with type 1 diabetes mellitus (n = 851 participants) that demonstrated a pooled mean difference of -0.13 (95% confidence interval -0.33 to 0.07), a non-significant decrease in favour of psychological treatment; 18 studies conducted in adolescents/children with type 1 diabetes mellitus (n = 2583 participants) that demonstrated a pooled mean difference of 0.00 (95% confidence interval -0.18 to 0.18), indicating no change; and 49 studies conducted in adults with type 2 diabetes mellitus (n = 12,009 participants) that demonstrated a pooled mean difference of -0.21 (95% confidence interval -0.31 to -0.10), equivalent to reduction in glycated haemoglobin levels of -0.33% or ≈3.5 mmol/mol. For type 2 diabetes mellitus, there was evidence that psychological interventions improved dietary behaviour and quality of life but not blood pressure, body mass index or depressive symptoms. The results of the network meta-analysis, which considers direct and indirect effects of multiple treatment comparisons, suggest that, for adults with type 1 diabetes mellitus (7 studies; 968 participants), attention control and cognitive-behavioural therapy are clinically effective and cognitive-behavioural therapy is cost-effective. For adults with type 2 diabetes mellitus (49 studies; 12,409 participants), cognitive-behavioural therapy and counselling are effective and cognitive-behavioural therapy is potentially cost-effective. The results of the individual patient data meta-analysis for adolescents/children with type 1 diabetes mellitus (9 studies; 1392 participants) suggest that there were main effects for age and diabetes duration. For adults with type 2 diabetes mellitus (19 studies; 3639 participants), baseline glycated haemoglobin levels moderated treatment outcome. LIMITATIONS Aggregate meta-analysis was limited to glycaemic control for type 1 diabetes mellitus. It was not possible to model cost-effectiveness for adolescents/children with type 1 diabetes mellitus and modelling for type 2 diabetes mellitus involved substantial uncertainty. The individual patient data meta-analysis included only 40-50% of studies. CONCLUSIONS This review suggests that psychological treatments offer minimal clinical benefit in improving glycated haemoglobin levels for adults with type 2 diabetes mellitus. However, there was no evidence of benefit compared with control interventions in improving glycated haemoglobin levels for people with type 1 diabetes mellitus. FUTURE WORK Future work should consider the competency of the interventionists delivering a therapy and psychological approaches that are matched to a person and their life course.

Abstract
IMPORTANCE Hyperglycemic crises (ie, diabetic ketoacidosis [DKA] and hyperglycemic hyperosmolar state [HHS]) are life-threatening acute complications of diabetes. Efforts to prevent these events at the population level have been hindered by scarce granular data and difficulty in identifying individuals at highest risk. OBJECTIVE To assess sociodemographic, clinical, and treatment-related factors associated with hyperglycemic crises in adults with type 1 or type 2 diabetes in the US from 2014 to 2020. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study analyzed administrative claims and laboratory results for adults (aged ≥18 years) with type 1 or type 2 diabetes from the OptumLabs Data Warehouse from January 1, 2014, through December 31, 2020. MAIN OUTCOMES AND MEASURES Rates of emergency department or hospital visits with a primary diagnosis of DKA or HHS (adjusted for age, sex, race/ethnicity, and region, and for year when calculating annualized rates) were calculated separately for patients with type 1 diabetes and type 2 diabetes. The associations of sociodemographic factors (age, sex, race/ethnicity, region, and income), clinical factors (comorbidities), and treatment factors (glucose-lowering medications, hemoglobin A1c) with DKA or HHS in patients with type 1 or type 2 diabetes were assessed using negative binomial regression. RESULTS Among 20 156 adults with type 1 diabetes (mean [SD] age, 46.6 [16.5] years; 51.2% male; 72.6% White race/ethnicity) and 796 382 with type 2 diabetes (mean [SD] age, 65.6 [11.8] years; 50.3% female; 54.4% White race/ethnicity), adjusted rates of hyperglycemic crises were 52.69 per 1000 person-years (95% CI, 48.26-57.12 per 1000 person-years) for type 1 diabetes and 4.04 per 1000 person-years (95% CI, 3.88-4.21 per 1000 person-years) for type 2 diabetes. In both groups, factors associated with the greatest hyperglycemic crisis risk were low income (≥$200 000 vs <$40 000: type 1 diabetes incidence risk ratio [IRR], 0.61 [95% CI, 0.46-0.81]; type 2 diabetes IRR, 0.69 [95% CI, 0.56-0.86]), Black race/ethnicity (vs White race/ethnicity: type 1 diabetes IRR, 1.33 [95% CI, 1.01-1.74]; type 2 diabetes IRR, 1.18 [95% CI, 1.09-1.27]), high hemoglobin A1c level (≥10% vs 6.5%-6.9%: type 1 diabetes IRR, 7.81 [95% CI, 5.78-10.54]; type 2 diabetes IRR, 7.06 [95% CI, 6.26-7.96]), history of hyperglycemic crises (type 1 diabetes IRR, 7.88 [95% CI, 6.06-9.99]; type 2 diabetes IRR, 17.51 [95% CI, 15.07-20.34]), severe hypoglycemia (type 1 diabetes IRR, 2.77 [95% CI, 2.15-3.56]; type 2 diabetes IRR, 4.18 [95% CI, 3.58-4.87]), depression (type 1 diabetes IRR, 1.62 [95% CI, 1.37-1.92]; type 2 diabetes IRR, 1.46 [95% CI, 1.34-1.59]), neuropathy (type 1 diabetes IRR, 1.64 [95% CI, 1.39-1.93]; type 2 diabetes IRR, 1.25 [95% CI, 1.17-1.34]), and nephropathy (type 1 diabetes IRR, 1.22 [95% CI, 1.01-1.48]; type 2 diabetes IRR, 1.23 [95% CI, 1.14-1.33]). Age had a U-shaped association with hyperglycemic crisis risk in patients with type 1 diabetes (compared with patients aged 18-44 years: 45-64 years IRR, 0.72 [95% CI, 0.59-0.87]; 65-74 years IRR, 0.62 [95% CI, 0.47-0.80]; ≥75 years IRR, 0.96 [95% CI, 0.66-1.38]). In type 2 diabetes, risk of hyperglycemic crises decreased progressively with age (45-64 years IRR, 0.57 [95% CI, 0.51-0.63]; 65-74 years IRR, 0.44 [95% CI, .39-0.49]; ≥75 years IRR, 0.41 [95% CI, 0.36-0.47]). In patients with type 2 diabetes, higher risk was associated with sodium-glucose cotransporter 2 inhibitor therapy (IRR, 1.30; 95% CI, 1.14-1.49) and insulin dependency (compared with regimens with bolus insulin: regimens with basal insulin only, IRR, 0.69 [95% CI, 0.63-0.75]; and without any insulin, IRR, 0.36 [95% CI, 0.33-0.40]). CONCLUSIONS AND RELEVANCE In this cohort study, younger age, Black race/ethnicity, low income, and poor glycemic control were associated with an increased risk of hyperglycemic crises. The findings suggest that multidisciplinary interventions focusing on groups at high risk for hyperglycemic crises are needed to prevent these dangerous events.

BMC Health Serv Res 2021; 21:682. [PMID: 34246266 PMCID: PMC8272902 DOI: 10.1186/s12913-021-06715-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 06/29/2021] [Indexed: 11/10/2022] Open
Abstract
Background Diabetic ketoacidosis causes a significant number of hospitalisations worldwide, with rates tending to increase with remoteness and socioeconomic disadvantage. Our study aimed to explore healthcare professionals’ perceptions of factors affecting presentation of people with type 1 diabetes in a low socioeconomic area of Queensland, Australia. Methods This was a qualitative study. Individual semi-structured face-to-face or telephone interviews were completed with patients with type 1 diabetes who had presented in diabetic ketoacidosis, and healthcare professionals who have experience in related care. Data were analysed using Gibbs’s framework of thematic analysis. Results Four patients with type 1 diabetes and 18 healthcare professionals were interviewed. Restricted access was identified as a factor contributing to diabetic ketoacidosis and delayed presentation, with ketone testing supplies, continuous glucose monitoring technology and transport considered barriers. Many of these factors were arguably preventable. Opportunities to improve the care available to patients with type 1 diabetes were detailed, with particularly strong support for dedicated out of hours telephone help lines for adults with type 1 diabetes. Conclusions Gaps in support for patient self-care to avoid diabetic ketoacidosis presentations and prevent late presentation of diabetic ketoacidosis revealed by this study require service reconfiguration to support care delivery. Until change is made, people with type 1 diabetes will continue to make both avoidable and delayed, acutely unwell, presentations to Emergency Departments.

Important Drop in Rate of Acute Diabetes Complications in People With Type 1 or Type 2 Diabetes After Initiation of Flash Glucose Monitoring in France: The RELIEF Study. Diabetes Care 2021; 44:1368-1376. [PMID: 33879536 PMCID: PMC8247513 DOI: 10.2337/dc20-1690] [Citation(s) in RCA: 62] [Impact Index Per Article: 20.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Accepted: 03/02/2021] [Indexed: 02/03/2023]
Abstract
OBJECTIVE The RELIEF study assessed rates of hospitalization for acute diabetes complications in France before and after initiation of the FreeStyle Libre system. RESEARCH DESIGN AND METHODS A total of 74,011 patients with type 1 diabetes or type 2 diabetes who initiated the FreeStyle Libre system were identified from the French national claims database with use of ICD-10 codes, from hospitalizations with diabetes as a contributing diagnosis, or the prescription of insulin. Patients were subclassified based on self-monitoring of blood glucose (SMBG) strip acquisition prior to starting FreeStyle Libre. Hospitalizations for diabetic ketoacidosis (DKA), severe hypoglycemia, diabetes-related coma, and hyperglycemia were recorded for the 12 months before and after initiation. RESULTS Hospitalizations for acute diabetes complications fell in type 1 diabetes (-49.0%) and in type 2 diabetes (-39.4%) following FreeStyle Libre initiation. DKA fell in type 1 diabetes (-56.2%) and in type 2 diabetes (-52.1%), as did diabetes-related comas in type 1 diabetes (-39.6%) and in type 2 diabetes (-31.9%). Hospitalizations for hypoglycemia and hyperglycemia decreased in type 2 diabetes (-10.8% and -26.5%, respectively). Before initiation, hospitalizations were most marked for people noncompliant with SMBG and for those with highest acquisition of SMBG, which fell by 54.0% and 51.2%, respectively, following FreeStyle Libre initiation. Persistence with FreeStyle Libre at 12 months was at 98.1%. CONCLUSIONS This large retrospective study on hospitalizations for acute diabetes complications shows that a significantly lower incidence of admissions for DKA and for diabetes-related coma is associated with use of flash glucose monitoring. This study has significant implications for patient-centered diabetes care and potentially for long-term health economic outcomes.

Abstract
Diabetic ketoacidosis (DKA) is an acute complication of diabetes mellitus that can be associated with increased morbidity and mortality, particularly if it is diagnosed late and not treated appropriately. The management of DKA includes careful clinical evaluation, correction of metabolic abnormalities with intravenous fluids, insulin and electrolyte replacement with frequent monitoring of the patients' clinical and laboratory findings and also identification and treatment of the precipitating condition. There are special populations where features, management and outcome may differ from the usual patient with diabetes. Data on management of DKA in such special populations such as chronic kidney disease and pregnancy are sparse and recommendations are based mainly on small case series and expert opinion. Clinicians need to recognize and manage euglycaemic DKA in patients prescribed sodium-glucose cotransporter inhibitors. DKA is particularly a major health concern due to high rates of hospital admissions and mortality in resource-limited settings due to financial constraints, limiting the adequate provision of insulin and access to health care systems, and dysfunctional health systems. We review the challenges of diagnosis and management of DKA in these specific groups and provide recommendations on optimal patient care.

Abstract
BACKGROUND AND AIMS Diabetic ketoacidosis (DKA) treatment guidelines recommend to initiate potassium-replacement when serum potassium (SK) drops within normal range, and to withhold insulin if SK is below normal. Despite strict recommendations, hypokalemia is frequently observed in DKA. METHODS Scientific literature was thoroughly searched to find 1) DKA treatment guidelines, 2) studies reporting hypokalemia in DKA, 3) and literature elaborating mechanisms involved in hypokalemia. RESULTS Acidosis affects SK and its regulators including insulin, catecholamines and aldosterone. Current conceptual framework is an argument to gauge the degree of hypokalemia before it strikes DKA patients utilizing SK level after adjusting it with pH. Suggested approach will reduce hypokalemia risk and its associated complications. The nomogram calculates pH-adjusted potassium and expected potassium loss. It also ranks hypokalemia associated risk, and proposes the potassium-replacement rate over given time period. The differences between current DKA treatment guidelines and proposed strategy are also discussed. Moreover, reasons and risk of hyperkalemia due to early initiation of potassium replacement and remedial actions are debated. CONCLUSION In light of proposed strategy, utilizing the nomogram ensures reduced incidence of hypokalemia in DKA resulting in improved clinical and patient outcomes. Pharmacoeconomic benefits can also be expected when avoiding hypokalemia ensures early discharge.

Abstract
Diabetes is the fourth cause of death globally. To date, there is not a practical, as well as an accurate sample for reflecting chronic glucose levels. We measured earwax glucose in 37 controls. Participants provided standard serum, glycated hemoglobin (HbA1c) and earwax samples at two time-points, one month apart. The specimens measured baseline fasting glucose, a follow-up postprandial glucose level and a between sample chronic glucose, calculated using the average level on the two occasions. The baseline earwax sample was obtained using a clinical method and the follow-up using a novel self-sampling earwax device. The earwax analytic time was significantly faster using the novel device, in comparison to the clinical use of the syringe. Earwax accurately reflected glucose at both assessments with stronger correlations than HbA1c. Follow-up postprandial concentrations were more significant than their respective fasting baseline concentrations, reflecting differences in fasting and postprandial glycemia and more efficient standardization at follow up. Earwax demonstrated to be more predictable than HbA1c in reflecting systemic fasting, postprandial and long-term glucose levels, and to be less influenced by confounders. Earwax glucose measurements were approximately 60% more predictable than HbA1c in reflecting glycemia over a month. The self-sampling device provided a sample that might accurately reflect chronic glycemia.

Abstract
Diabetic ketoacidosis (DKA) is the most common hyperglycemic emergency and causes the greatest risk for death in patients with diabetes mellitus. DKA more commonly occurs among those with type 1 diabetes, yet almost a third of the cases occur among those with type 2 diabetes. Although mortality rates from DKA have declined to low levels in general, it continues to be high in many developing countries. DKA is characterized by hyperglycemia, metabolic acidosis and ketosis. Proper management of DKA requires hospitalization for aggressive intravenous fluids, insulin therapy, electrolyte replacement as well as identification and treatment of the underlying precipitating event along with frequent monitoring of patient's clinical and laboratory states. The most common precipitating causes for DKA include infections, new diagnosis of diabetes and nonadherence to insulin therapy. Clinicians should be aware of the occurrence of DKA in patients prescribed sodium-glucose co-transporter 2 inhibitors. Discharge plans should include appropriate choice and dosing of insulin regimens and interventions to prevent recurrence of DKA. Future episodes of DKA can be reduced through patient education programs focusing on adherence to insulin and self-care guidelines during illness and improved access to medical providers. New approaches such as extended availability of phone services, use of telemedicine and utilization of public campaigns can provide further support for the prevention of DKA.

Abstract
BACKGROUND Diabetes is a chronic condition that can lead to devastating complications if not managed effectively. Individuals with elevated HbA1c are at higher risk of developing complications resulting in diabetes-related hospital admissions, an additional pressure and expense for healthcare systems. AIM To systematically review evidence of the effectiveness of psychosocial interventions among individuals with elevated HbA1c , as indicated by hospital admissions. METHODS Electronic databases (MEDLINE, PsychINFO, CINAHL, AMED, Embase and Scopus) were used to identify studies systematically. Studies were screened against eligibility criteria and included if they evaluated the effectiveness of a psychosocial intervention on diabetes-related hospital admissions in individuals with elevated HbA1c . Risk of bias was assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies, and a narrative synthesis was conducted. RESULTS Of 15 362 studies, five were included in the review. Psychosocial interventions were found to significantly reduce diabetes-related hospital admissions in four of these studies and interventions involving psychotherapy in particular were found to reduce admissions. The methodological quality of studies ranged from weak to moderate, due to lack of blinding, weak study design and issues with withdrawals and drop-outs. CONCLUSIONS Psychosocial interventions may reduce diabetes-related hospital admissions in individuals with elevated HbA1c ; however, due to variability in methodological rigour, the conclusion remains tentative. Further research targeting this group, particularly within the adult population, is recommended. (PROSPERO registration number: CRD42019133456).

Abstract
Diabetic ketoacidosis (DKA) is the most common acute hyperglycaemic emergency in people with diabetes mellitus. A diagnosis of DKA is confirmed when all of the three criteria are present - 'D', either elevated blood glucose levels or a family history of diabetes mellitus; 'K', the presence of high urinary or blood ketoacids; and 'A', a high anion gap metabolic acidosis. Early diagnosis and management are paramount to improve patient outcomes. The mainstays of treatment include restoration of circulating volume, insulin therapy, electrolyte replacement and treatment of any underlying precipitating event. Without optimal treatment, DKA remains a condition with appreciable, although largely preventable, morbidity and mortality. In this Primer, we discuss the epidemiology, pathogenesis, risk factors and diagnosis of DKA and provide practical recommendations for the management of DKA in adults and children.

Abstract
Diabetic ketoacidosis (DKA) is a serious acute complication of type 1 diabetes, which is receiving more attention given the increased DKA risk associated with SGLT inhibitors. Sociodemographic and modifiable risk factors were identified with strong evidence for an increased risk of DKA, including socioeconomic disadvantage, adolescent age (13-25 years), female sex, high HbA1c, previous DKA, and psychiatric comorbidities (eg, eating disorders and depression). Possible prevention strategies, which include the identification of people at risk based on non-modifiable sociodemographic risk factors, are proposed. As a second risk mitigation strategy, structured diabetes self-management education that addresses modifiable risk factors can be used. Evidence has found that structured education leads to reduced DKA rates. Knowledge of these risk factors and potent risk mitigation strategies are important to identify subgroups of people with an elevated DKA risk. This knowledge should also be used when adjunct therapy options with an increased DKA risk are considered. Prevention of DKA in people with type 1 diabetes is an important clinical task, which should also be addressed when SGLT inhibitors are part of therapy.

Abstract
AIMS Diabetic ketoacidosis (DKA) remains one of the most frequently encountered diabetes related emergencies, and despite updates in management and increasing standardisation of care, still has an appreciable morbidity and mortality. This review focusses on the pathophysiology and epidemiology of DKA, but also on the importance of having a standardised definition. METHODS Relevant data were reviewed where there was available basic science or clinical papers published in peer-reviewed international journals on DKA. These included consensus documents and national or international guidelines. RESULTS The prevalence of DKA varies around the world, but part of this could be down to the way the condition is defined. Examples of this difference include the recent studies on sodium glucose co-transporter inhibitors in people with type 1 and type 2 diabetes which have all been associated with increased rates of DKA, but have highlighted how differences in definitions can make comparisons between agents very difficult. CONCLUSIONS DKA should only be diagnosed when all three components are present - the 'D', the 'K' and the 'A'. In addition, the definitions used to diagnose DKA should be standardised - in particular for clinical trials.

Abstract
AIMS Adolescents with Type 1 diabetes commonly experience episodes of ketoacidosis. In 2014, we conducted a nationwide survey on the management of diabetic ketoacidosis in young people. The survey reported how individual adolescents with diabetes were managed. However, the costs of treating diabetic ketoacidosis were not reported. METHODS Using this mixed population sample of adolescents, we took a 'bottom-up' approach to cost analysis aiming to determine the total expense associated with treating diabetic ketoacidosis. The data were derived using the information from the national UK survey of 71 individuals, collected via questionnaires sent to specialist paediatric diabetes services in England and Wales. RESULTS Several assumptions had to be made when analysing the data because the initial survey collection tool was not designed with a health economic model in mind. The mean time to resolution of diabetic ketoacidosis was 15.0 h [95% confidence interval (CI) 13.2, 16.8] and the mean total length of stay was 2.4 days (95% CI 1.9, 3.0). Based on data for individuals and using the British Society of Paediatric Endocrinology and Diabetes (BSPED) guidelines, the cost analysis shows that for this cohort, the average cost for an episode of diabetic ketoacidosis was £1387 (95% CI 1120, 1653). Regression analysis showed a significant cost saving of £762 (95% CI 140, 1574; P = 0.04) among those treated using BSPED guidelines. CONCLUSION We have used a bottom-up approach to calculate the costs of an episode of diabetic ketoacidosis in adolescents. These data suggest that following treatment guidelines can significantly lower the costs for managing episodes of diabetic ketoacidosis.

Abstract
Diabetic ketoacidosis and hyperosmolar hyperglycemic syndrome (HHS) are life threatening complications that occur in patients with diabetes. In addition to timely identification of the precipitating cause, the first step in acute management of these disorders includes aggressive administration of intravenous fluids with appropriate replacement of electrolytes (primarily potassium). In patients with diabetic ketoacidosis, this is always followed by administration of insulin, usually via an intravenous insulin infusion that is continued until resolution of ketonemia, but potentially via the subcutaneous route in mild cases. Careful monitoring by experienced physicians is needed during treatment for diabetic ketoacidosis and HHS. Common pitfalls in management include premature termination of intravenous insulin therapy and insufficient timing or dosing of subcutaneous insulin before discontinuation of intravenous insulin. This review covers recommendations for acute management of diabetic ketoacidosis and HHS, the complications associated with these disorders, and methods for preventing recurrence. It also discusses why many patients who present with these disorders are at high risk for hospital readmissions, early morbidity, and mortality well beyond the acute presentation.

Thalange N, Gundgaard J, Parekh W, Tutkunkardas D. Cost analysis of insulin degludec in comparison with insulin detemir in treatment of children and adolescents with type 1 diabetes in the UK. BMJ Open Diabetes Res Care 2019; 7:e000664. [PMID: 31543973 PMCID: PMC6731813 DOI: 10.1136/bmjdrc-2019-000664] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2019] [Revised: 07/03/2019] [Accepted: 07/25/2019] [Indexed: 12/23/2022] Open
Abstract
OBJECTIVE With healthcare systems under increasing financial pressure from costs associated with diabetes care, it is important to assess which treatments provide clinical benefits and represent best value. This study evaluated the annual costs of insulin degludec (degludec) versus insulin detemir (IDet) in children and adolescents with type 1 diabetes (T1D) in the UK. RESEARCH DESIGN AND METHODS Using data from a randomized, treat-to-target, non-inferiority trial-BEGIN YOUNG 1-annual costs with degludec versus IDet in children and adolescents aged 1-17 years with T1D were estimated, as costs of these insulins and hyperglycemia with ketosis events. Analyses by age group (1-5, 6-11 and 12-17 years) and scenario (no ketosis benefit, no dose benefit, hyperglycemia with ketones >0.6 and >3.0 mmol/L and the additional costs of twice-daily IDet in 64% of patients) were also performed. RESULTS The mean annual cost per patient was estimated as £235.16 for degludec vs £382.91 for IDet, resulting in an annual saving of £147.75 per patient. These substantial cost savings were driven by relative reductions in the frequency of hyperglycemia with ketosis and basal insulin dose with degludec versus IDet. Annual savings in favor of degludec were observed across each age group (£122.63, £140.59 and £172.50 for 1-5, 6-11 and 12-17 years age groups, respectively). Five scenario analyses further demonstrated the robustness of the results, which included no ketosis or dose benefits in favor of degludec. CONCLUSIONS Degludec provides appreciable annual cost savings compared with IDet in children and adolescents with T1D in a UK setting. While a cost-effectiveness analysis could incorporate the health impact of treatment complications better than the present cost analysis, the strong generalizability of the data from this study suggests that degludec can help healthcare providers to maximize health outcomes despite increasingly stringent budgets.

Abstract
Diabetic ketoacidosis (DKA) is a complication seen in patients with both type 1 and type 2 diabetes. Due to its large, growing economic impact with associated morbidity, closer look at proper management is important. Factors involved in appropriate management involves fluid resuscitation, insulin regimen, and electrolyte replacement including types of fluid and insulin treatment. The caveat with generalized protocol is application to special populations such as renal or heart failure patients the sequelae of complications due to pathophysiology of the disease processes. This leads to complications and longer length of stay in the hospital, therefore, possibly increased cost and resource utilization during the hospitalization. This review takes a closer look at current guidelines of DKA management and resource utilization, the drawbacks of current management protocols and the cost associated with it. Therefore, a need for amendment to existing protocol or initiation of a newer guideline that properly manages DKA should incorporate special populations and appropriate regimen of fluid resuscitation, insulin therapy and electrolyte management.

Diabetes Care 2018; 41:1870-1877. [PMID: 29386248 DOI: 10.2337/dc17-1583] [Citation(s) in RCA: 88] [Impact Index Per Article: 14.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2017] [Accepted: 12/30/2017] [Indexed: 02/03/2023]
Abstract
OBJECTIVE This study determined trends in hospital admission for diabetic ketoacidosis (DKA) in adults with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) from 1998 to 2013 in England. RESEARCH DESIGN AND METHODS The study population included 23,246 adults with T1DM and 241,441 adults with T2DM from the Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES). All hospital admissions for DKA as the primary diagnosis from 1998 to 2013 were identified. Trends in hospital admission for DKA in incidence, length of hospital stay, 30-day all-cause readmission rate, and 30-day and 1-year all-cause mortality rates were determined using joinpoint regression, negative binomial regression, and logistic regression models. RESULTS For T1DM, the incidence of hospital admission for DKA increased between 1998 and 2007 and remained static until 2013. The incidence in 2013 was higher than that in 1998 (incidence rate ratio 1.53 [95% CI 1.09-2.16]). For T2DM, the incidence increased 4.24% (2.82-5.69) annually between 1998 and 2013. The length of hospital stay decreased over time for both diabetes types (P ≤ 0.0004). Adults with T1DM were more likely to be discharged within 2 days compared with adults with T2DM (odds ratio [OR] 1.28 [1.07-1.53]). The 30-day readmission rate was higher in T1DM than in T2DM (OR 1.61 [1.04-2.50]) but remained unchanged for both diabetes types over time. Trends in 30-day and 1-year all-cause mortality rates were also stable, with no difference by diabetes type. CONCLUSIONS In the previous two decades in England, hospitalization for DKA increased in adults with T1DM and in those with T2DM, and associated health care performance did not improve except decreased length of hospital stay.
