Incidence and care-related costs of severe hypoglycaemia requiring emergency treatment in Andalusia (Spain): the PAUEPAD project

Population-Based Study on the Implementation of Flash Glucose Monitoring and Severe Hypoglycemia in Adults With Type 1 Diabetes

Objective: We analyzed the effect of implementing a flash glucose monitoring (FGM) technology in a public health care system with universal coverage on the rate of severe hypoglycemia requiring urgent care in adults with type 1 diabetes mellitus (T1DM). Methods: Using a comprehensive regional dataset, we extracted emergency care codes with hypoglycemia in individuals with T1DM who initiated the use of FGM in Andalucia, Spain, from January 1, 2020, to December 31, 2021. Severe hypoglycemia was defined as a confirmed blood glucose <70 mg/dL, which required the urgent dispatch of an emergency medical service (EMS) for onsite management. We compared hypoglycemic events reported in the 12 months before and after the initiation of FGM to determine the population incidence rates. Results: A total of 13,616 participants with a mean age of 43.7 ± 13.5 years were included. The follow-up periods were 23.4 and 24.8 months before and after FGM. There were 969 and 737 cases of hypoglycemia before and after the initiation of FGM. The baseline incidence rate was 358.58 episodes per 10,000 person-years, which decreased to 260.9 at the end of the follow-up (rate-ratio 0.72 [0.66; 0.80]). The reduction in hypoglycemia was significant in individuals aged ≥60 years (rate-ratio 0.40 [0.28; 0.55]) and males (0.64 [0.56; 0.72]). In addition, there was a reduction in the overall median HbA1c of -0.35% (95% CI [-0.38; -0.33], P < 0.001). Conclusion: The implementation of FGM systems in a public health care system as a provision for adults with T1DM was associated with significant reductions in the rate of severe hypoglycemic events that required urgent EMS care.

Frailty Detection in Older Adults with Diabetes: A Scoping Review of Assessment Tools and Their Link to Key Clinical Outcomes

Objectives: With the increasing prevalence of diabetes and frailty among older adults, there is an urgent need for precision medicine that incorporates comprehensive geriatric assessments, including frailty detection. This scoping review aims to map and synthesize the available evidence on validated tools for detecting pre-frailty and frailty in community-dwelling elderly individuals with diabetes and outpatient diabetes patients. Specifically, it addresses: (1) What validated tools are available for detecting pre-frailty and frailty in this population? (2) How are these tools associated with outcomes such as glycemic control, hypoglycemia, and metabolic phenotypes? (3) What gaps exist in the literature regarding these tools? Methods: The review followed PRISMA-ScR guidelines, conducting a systematic search across PubMed, Cochrane Library, and Web of Science. The inclusion criteria focused on studies involving individuals aged 70 years and older with diabetes, emphasizing tools with predictive capacity for disability and mortality. Results: Eight instruments met the inclusion criteria, including the Frailty Index, Physical Frailty Phenotype, and Clinical Frailty Scale. These tools varied in domains such as physical, psychological, and social aspects of frailty and their association with glycemic control, hypoglycemia, and metabolic phenotypes. The review identified significant gaps in predicting diabetes-related complications and their clinical application. Conclusions: Routine management of older adults with diabetes should incorporate frailty detection, as it is crucial for their overall health. Although widely used, the reviewed tools require refinement to address the unique characteristics of this population. Developing tailored instruments will enhance precision medicine, leading to more effective, individualized interventions for elderly individuals with diabetes.

People With Diabetes and Caregivers Prefer Rescue Glucagon Treatment With a Wider Storage Temperature Range and a Nasal Administration, When Efficacy is Similar: A Discrete Choice Experiment in Spain

BACKGROUND

Conventional injectable glucagon (IG) and nasal glucagon (NG), both having similar efficacy, are two options for the emergency treatment of severe hypoglycemia in Spain. This study elicited the effect of changes in key attributes on preferences for NG and IG medication profiles of people with diabetes and caregivers in Spain.

METHODS

The relative attribute importance (RAI) that participants placed on glucagon preparation, preparation and administration time, delivery method, recovery time, device size, storage temperature, and headache risk was estimated from an online discrete choice experiment. In addition, patients and caregivers were presented with NG and IG profiles that included rates of successful administration; the proportion of participants choosing each profile was summarized.

RESULTS

The analysis included 276 adults with diabetes (65% type 1) and 270 caregivers (49% type 1). Overall mean age was 40 years; 51% were female. The most important attributes were storage temperature (RAI [95% confidence interval] = 27.3% [22.9-32.2]) and delivery method (17.4% [13.1-21.9]). Headache risk (16.2% [11.8-20.7]), time to prepare and administer (14.5% [10.1-18.8]), glucagon preparation (11.4% [6.8-15.8]), recovery time (8.9% [4.3-13.3]), and device size (4.3% [0.3-8.8]) were also relevant. When comparing medication profiles, significantly more participants (78%) preferred NG over IG profiles (P < .001).

CONCLUSION

Adults with diabetes and caregivers prefer a glucagon treatment with a higher rate of successful administration, wider storage temperature, and nasal delivery method, when efficacy is similar. Participants favored NG over conventional IG as a rescue medication for severe hypoglycemia. This information may help decision-making by payers and treatment discussions between health care professionals and patients.

Changes in attitudes to awareness of hypoglycaemia during a hypoglycaemia awareness restoration programme are associated with avoidance of further severe hypoglycaemia episodes within 24 months: the A2A in HypoCOMPaSS study

AIMS/HYPOTHESIS

The aims of this study were to assess cognitions relating to hypoglycaemia in adults with type 1 diabetes and impaired awareness of hypoglycaemia before and after the multimodal HypoCOMPaSS intervention, and to determine cognitive predictors of incomplete response (one or more severe hypoglycaemic episodes over 24 months).

METHODS

This analysis included 91 adults with type 1 diabetes and impaired awareness of hypoglycaemia who completed the Attitudes to Awareness of Hypoglycaemia (A2A) questionnaire before, 24 weeks and 24 months after the intervention, which comprised a short psycho-educational programme with optimisation of insulin therapy and glucose monitoring.

RESULTS

The age and diabetes duration of the participants were 48±12 and 29±12 years, respectively (mean±SD). At baseline, 91% reported one or more severe hypoglycaemic episodes over the preceding 12 months; this decreased to <20% at 24 weeks and after 24 months (p=0.001). The attitudinal barrier 'hyperglycaemia avoidance prioritised' (η²_p=0.250, p=0.001) decreased from baseline to 24 weeks, and this decrease was maintained at 24 months (mean±SD=5.3±0.3 vs 4.3±0.3 vs 4.0±0.3). The decrease in 'asymptomatic hypoglycaemia normalised' from baseline (η²_p=0.113, p=0.045) was significant at 24 weeks (1.5±0.3 vs 0.8±0.2). Predictors of incomplete hypoglycaemia response (one or more further episodes of severe hypoglycaemia) were higher baseline rates of severe hypoglycaemia, higher baseline scores for 'asymptomatic hypoglycaemia normalised', reduced change in 'asymptomatic hypoglycaemia normalised' scores at 24 weeks, and lower baseline 'hypoglycaemia concern minimised' scores (all p<0.05).

CONCLUSIONS/INTERPRETATION

Participation in the HypoCOMPaSS RCT was associated with improvements in hypoglycaemia-associated cognitions, with 'hyperglycaemia avoidance prioritised' most prevalent. Incomplete prevention of subsequent severe hypoglycaemia episodes was associated with persistence of the cognition 'asymptomatic hypoglycaemia normalised'. Understanding and addressing cognitive barriers to hypoglycaemia avoidance is important in individuals prone to severe hypoglycaemia episodes.

Impact on variables of severe hypoglycaemia and healthcare costs of the use of the FreeStyle system in paediatric population with type 1 diabetes mellitus

INTRODUCTION

Analysis of the impact on severe hypoglycaemia and direct costs of the introduction of the FreeStyle Libre sensor in paediatric population with type 1 Diabetes Mellitus.

MATERIAL AND METHODS

Ambispective single-centre study to assess the impact on severe hypoglycaemia and direct costs, focusing on consumption of materials, in paediatric population with type 1 Diabetes Mellitus before and after introduction of the FreeStyle Libre 1 sensor.

RESULTS

A significant decrease was found in episodes of severe hypoglycaemia, with 4.2 episodes of severe hypoglycaemia per 100 patients under follow-up versus 0.25 episodes per 100 patients a year after introduction of the system. This represents a cost difference for severe hypoglycaemia, estimated at €6559.52 before introduction and €409.97 after introduction of the FreeStyle Libre sensor. We found a decrease in the daily consumption of capillary blood glucose strips, which translates as a decrease in the cost of materials and helps mitigate the cost of the sensor. The cost in materials for the patient with FreeStyle Libre was €185.13 per patient and year higher than conventional control with capillary blood glucose strips.

Cost of Severe Hypoglycemia and Budget Impact with Nasal Glucagon in Patients with Diabetes in Spain

INTRODUCTION

Severe hypoglycemic events (SHE) represent a clinical and economic burden in patients with diabetes. Nasal glucagon (NG) is a novel treatment for SHEs with similar efficacy, but with a usability advantage over injectable glucagon (IG) that may translate to improved economic outcomes. The economic implications of this usability advantage on SHE-related spending in Spain were explored in this analysis.

METHODS

A cost-offset and budget impact analysis (BIA) was conducted using a decision tree model, adapted for the Spanish setting. The model calculated average costs per SHE over the SHE treatment pathway following a treatment attempt with IG or NG. Analyses were performed separately in three populations with insulin-treated diabetes: children and adolescents (4-17 years) with type 1 diabetes (T1D), adults with T1D and adults with type 2 diabetes (T2D), with respective population estimates applied in BIA. Treatment probabilities were assumed to be equal for IG and NG, except for treatment success following glucagon administration. Epidemiologic and cost data were obtained from Spanish-specific sources. BIA results were presented at a 3-year time horizon.

RESULTS

On a per SHE level, NG was associated with lower costs compared to IG (children and adolescents with T1D, EUR 820; adults with T1D, EUR 804; adults with T2D, EUR 725). Lower costs were attributed to reduced costs of professional medical assistance in patients treated with NG. After 3 years, BIA showed that relative to IG, the introduction of NG was projected to reduce SHE-related spending by EUR 1,158,969, EUR 142,162,371, and EUR 6,542,585 in children and adolescents with T1D, adults with T1D, and adults with insulin-treated T2D, respectively.

CONCLUSIONS

In Spain, the usability advantage of NG over IG translates to potential cost savings per SHE in three populations with insulin-treated diabetes, and the introduction of NG was associated with a lower budget impact versus IG in each group.

Evaluation of knowledge, barriers, and attitudes in the management of type 2 diabetes in elderly patients: A Delphi study on primary and hospital care

OBJECTIVES

This work aims to explore attitudes regarding the management of elderly or frail patients with type 2 diabetes mellitus in the routine clinical practice of a multidisciplinary group of physicians in Spain.

METHODS

A mixed survey was used that included both Delphi and opinion, attitude, and behaviour (OAB) questions. Perceptions in primary care (n = 211) and hospital care (n = 80) were compared.

RESULTS

Consensus was obtained on all statements. Eighty-seven percent of participants considered that severe psychiatric disorders conditioned antidiabetic treatment and 72% that a psychocognitive assessment is as relevant as the assessment of other comorbidities. Hospital care physicians more frequently considered that comorbidity affects self-care (95.0% vs. 82.9%), that a lack of de-intensification is a form of therapeutic inertia (88.8% vs. 76.3%), that classifying older adults as frail is fundamental to choosing targets (96.3% vs. 87.7%), that de-intensification of antidiabetic treatment and control of cardiovascular risk factors should be considered in those over 80 years of age (90.0% vs. 78.7%), and that type 2 diabetes mellitus predisposes patients to sarcopenia (86.3% vs. 71.6%). The usefulness of clinical guidelines was more highly valued among primary care participants (79.1% vs. 72.5%).

CONCLUSIONS

There is room for improvement on several aspects of managing elderly or frail patients with type 2 diabetes mellitus, including inertia in treatment de-intensification, conducting a psychocognitive assessment, or the identification of frailty and sarcopenia.

Adherence to antidiabetic treatment and impaired hypoglycemia awareness in type 2 diabetes mellitus assessed in Spanish community pharmacies: the ADHIFAC study

INTRODUCTION

Adherence to treatment and hypoglycemia awareness are strongly linked to glycemic control and hypoglycemia risk in people with type 2 diabetes mellitus (T2DM). Community pharmacies are suitable facilities to detect these conditions, and should be involved in the strategies to minimize the associated risks and burden.

RESEARCH DESIGN AND METHODS

This cross-sectional study conducted at community pharmacies across Spain assessed the prevalence of low adherence to antidiabetic treatments, the frequency of impaired hypoglycemia awareness, and their predictive factors. Adherence was measured with the 8-item Morisky Medication Adherence Scale (MMAS-8) and electronic records of dispensed treatments. The Clarke questionnaire was used to assess impaired hypoglycemia awareness. Healthcare counseling provided in the pharmacy was collected.

RESULTS

Seventy-nine pharmacists and 618 subjects with T2DM participated in the study. Mean age in the overall T2DM population was 67 years, being the majority (69%) pensioners. Adherence was high in 41% of participants, medium in 35%, and low in 24% according to the MMAS-8. Impaired hypoglycemia awareness was observed in 25% of participants. Main determinants of low adherence were the level of education, the number of treatments per patient, hypoglycemia awareness, and the type of pharmacy. Predictive factors of impaired hypoglycemia awareness were the level of education, information on diabetes-related complications, adherence levels, and the type of pharmacy. The proportion of participants who had healthcare counseling was 71% in the overall population and 100% in subjects with impaired hypoglycemia awareness and low adherence. Healthcare counseling comprised diabetes education (69%), pharmacotherapeutic assessment (20%), and physician referrals (11%).

CONCLUSION

Lack of adherence to antidiabetic treatments and impaired hypoglycemia awareness are frequent and correlate in T2DM. Community pharmacies can detect these conditions and should have an active role in the design of strategies to minimize them.

Hypoglycemia requiring paramedic assistance among adults in southwestern Ontario, Canada: a population-based retrospective cohort study

BACKGROUND

People with diabetes mellitus commonly experience hypoglycemia, but they may not necessarily present to hospital after severe hypoglycemia requiring paramedic assistance. We sought to describe the incidence and characteristics of calls for hypoglycemia requiring paramedic assistance among adults in southwestern Ontario, Canada, and to determine predictors of hospital transport.

METHODS

This population-based retrospective cohort study used data extracted from ambulance call reports (ACRs) of 8 paramedic services of the Southwest Ontario Regional Base Hospital Program from January 2008 to June 2014. We described calls in which treatment for hypoglycemia was administered, summarized the incidence of hypoglycemia calls and performed logistic regression to determine predictors of hospital transport.

RESULTS

Out of 470 467 ACRs during the study period, 9185 paramedic calls occurred in which hypoglycemia treatment was administered to an adult (mean age 60.2 yr, 56.8% male, 81.1% with documented diabetes). Refusal of hospital transport occurred in 2243 (24.4%) of calls. Documented diabetes diagnosis (adjusted odds ratio [OR] 0.82, 95% confidence interval [CI] 0.69-0.96), higher capillary blood glucose (adjusted OR 0.31, 95% CI 0.22-0.44) and overnight calls (adjusted OR 0.80, 95% CI 0.72-0.91) were associated with lower odds of hospital transport. Higher-acuity calls (adjusted OR 2.05, 95% CI 1.58-2.66) were associated with higher odds of transport. The estimated annual incidence rate of hypoglycemia requiring paramedic assistance was 108 per 10 000 people with diabetes per year.

INTERPRETATION

Hypoglycemia requiring paramedic assistance in southwestern Ontario is common, and close to 25% of calls do not result in hospital transport. Physicians managing diabetes care may be unaware of patients' hypoglycemia requiring paramedic care, suggesting a potential gap in follow-up care; we suggest that paramedics play an important role in identifying those at high recurrence risk and communicating with their care providers.

Conversations and Reactions Around Severe Hypoglycaemia (CRASH): Spanish results of a global survey of people with type 1 diabetes or insulin-treated type 2 diabetes and caregivers

INTRODUCTION

Information on experience/management of severe hypoglycaemic events (SHEs) among people with insulin-treated diabetes (PWD) and caregivers (CGs) providing care to PWD was sought.

MATERIALS AND METHODS

An online cross-sectional survey was conducted in eight countries.

INCLUSION CRITERIA

PWD (aged≥18 years; self-reported type 1 [T1D] or insulin-treated type 2 [T2D] diabetes; experienced ≥1 SHE [hypoglycaemia requiring external assistance] in past 3 years); CGs (layperson aged ≥18 years; caring for PWD meeting all criteria above except age [≥4 years]). This descriptive analysis provides data from Spain. SHE-associated data relate to the most recent SHE.

RESULTS

Across all groups (T1D PWD, n=106; T2D PWD, n=88, T1D CG, n=87; T2D CG, n=96), 76-89% reported that the SHE occurred at home; most common cause was eating less than planned (38-53%). Most usual action during the SHE was to intake carbohydrates (67-84%); glucagon use was low (9-36%). Discussion of the SHE with their healthcare provider (HCP) was reported by 70-75% of PWD. During the SHE, 35-69% of PWD/CGs reported feeling scared, unprepared and/or helpless.

CONCLUSIONS

Most SHEs occurred outside the healthcare setting; treatment therefore depends greatly on CGs. SHEs have a negative emotional impact on PWD/CGs, underscoring the need for HCPs to discuss SHEs with PWD/CGs, and to provide tools and strategies to prevent and effectively manage SHEs.

Cost Analysis of FreeStyle Libre® 2 System in Type 2 Diabetes Mellitus Population

INTRODUCTION

FreeStyle Libre^® 2 system is a sensor-based flash-monitoring system that measures interstitial fluid glucose. The study aimed to compare cost of FreeStyle Libre 2 system and self-monitoring of blood glucose (SMBG) in the type 2 diabetes mellitus (T2DM) population from the Spanish Health System perspective.

METHODS

On the basis of data collected from a literature review, the cost of glucose monitoring was modelled for patients with T2DM on a basal-bolus insulin regimen. The cost estimate included annual consumption for glucose monitoring (strips, lancets and sensors) and severe hypoglycaemic events (SHE) management. A published rate of SHE (2.5 episodes/patient-year) was considered. A reduction of SHE (- 48.8%) associated with FreeStyle Libre 2 system, derived from the REPLACE trial, was applied. Hospital attendance for 20.5% of SHEs (with subsequent hospitalization in 16.0%) was applied. Consumption of strips and lancets was set at 6/day for SMBG (derived from national monitoring recommendations), and 0.2/day for FreeStyle Libre 2 system users, with 26 FreeStyle Libre 2 sensors/year. Unitary costs (€, year 2020 excluding VAT) were derived from literature (€0.28/strip; €0.09/lancet; €3.09/daily FM sensor; €3804/hospitalized SHE; €1794/hospital-attended non-admitted SHE; €389/community-attended SHE).

RESULTS

Costs were €2700 and €2120/year/patient using SMBG or FreeStyle Libre 2 system, respectively. For 1000 patients with T2DM using basal-bolus insulin, 1220 SHEs/year (with 48 hospitalizations) could be prevented and FreeSytle Libre 2 system could generate cost savings of up to €580,953/year versus SMBG (- 21.5%).

CONCLUSION

FreeStyle Libre 2 system is a potential cost-saving strategy in patients with T2DM in Spain on a basal-bolus insulin regimen.

An analysis of frailty and multimorbidity in 20,566 UK Biobank participants with type 2 diabetes

Background

Frailty and multimorbidity are common in type 2 diabetes (T2D), including people <65 years. Guidelines recommend adjustment of treatment targets in people with frailty or multimorbidity. It is unclear how recommendations to adjust treatment targets in people with frailty or multimorbidity should be applied to different ages. We assess implications of frailty/multimorbidity in middle/older-aged people with T2D.

Methods

We analysed UK Biobank participants (n = 20,566) with T2D aged 40–72 years comparing two frailty measures (Fried frailty phenotype and Rockwood frailty index) and two multimorbidity measures (Charlson Comorbidity index and count of long-term conditions (LTCs)). Outcomes were mortality, Major Adverse Cardiovascular Event (MACE), hospitalization with hypoglycaemia or fall/fracture.

Results

Here we show  that choice of measure influences the population identified: 42% of participants are frail or multimorbid by at least one measure; 2.2% by all four measures. Each measure is associated with mortality, MACE, hypoglycaemia, and fall or fracture. The absolute 5-year mortality risk is higher in older versus younger participants with a given level of frailty (e.g. 1.9%, and 9.9% in men aged 45 and 65, respectively, using frailty phenotype) or multimorbidity (e.g. 1.3%, and 7.8% in men with 4 LTCs aged 45 and 65, respectively). Using frailty phenotype, the relationship between higher HbA1c and mortality is stronger in frail compared with pre-frail or robust participants.

Conclusions

Assessment of frailty/multimorbidity should be embedded within routine management of middle-aged and older people with T2D. Method of identification as well as features such as age impact baseline risk and should influence clinical decisions (e.g. glycaemic control).

Is hypoglycemia expensive in China?

BACKGROUND

As a common medical emergency in individuals with diabetes, hypoglycemia events can impose significant demands on hospital resources. Based on diabetes patients with and without hypoglycemia, we assess the cost of hypoglycemic events on China's hospital system.

METHOD

Our study sample comprised 7110 diabetes episodes, including 1417 patients with hypoglycemia (297 patients with severe and 1120 with non-severe hypoglycemia) and 5693 diabetes patients without hypoglycemia. Data on patient social-demographics, length of hospital stay, and hospitalization costs were collected on each patient from Health Information System in Shandong province, China. The additional hospital costs caused by hypoglycemia were assessed by the cost difference between diabetes patients with and without hypoglycemia, including severe and non-severe hypoglycemia. China-wide hospital costs of hypoglycemia were estimated based on adjusted additional hospital costs, comprising inspection, treatment, drugs, materials, nursing, general medical costs, and other costs, caused by hypoglycemia, the prevalence of diabetes and hypoglycemia events, and the rates of hospitalization. Multiple sensitivity analyses were conducted to assess the impact of variations in the key input parameters on the primary estimates.

RESULTS

Total hospital costs for patients with hypoglycemia (US$3020.61) were significantly higher than that of patients without hypoglycemia (US$1642.91). The average additional cost caused by hypoglycemia was US$1377.70, with higher average costs of US$1875.89 for severe hypoglycemia and lower average costs of US$1244.76 for non-severe hypoglycemia. The additional hospital cost caused by severe and non-severe hypoglycemia patients was higher for the 60 to 75 year old group, married patients and patients accessing free medical services. Generally, hypoglycemic patients with Urban and Rural Resident Basic Medical Insurance incurred higher additional hospital costs than patients with Urban Employees Basic Medical Insurance. Based on these estimates, the total annual additional hospital costs arising from hypoglycemia events in China were estimated to be US$67.52 million. Sensitivity analyses suggested that the costs of hypoglycemia events ranged up to US$49.99 million to 67.52 million.

CONCLUSION

: Hypoglycemic events imposed a substantial cost on China's hospital system, with certain subgroups of patients, such as older patients and those with free health insurance, using medical resources more intensively to treat hypoglycemia events. We recommend more effective planning of prevention and treatment regimes for hypoglycemia patients; further reform to China's health insurance schemes; and better hospital cost control for those accessing free hospital services.

Geographical clustering and socioeconomic factors associated with hypoglycemic events requiring emergency assistance in Andalusia (Spain)

INTRODUCTION

The geographical distribution of hypoglycemic events requiring emergency assistance was explored in Andalusia (Spain), and potentially associated societal factors were determined.

RESEARCH DESIGN AND METHODS

This was a database analysis of hypoglycemia requiring prehospital emergency assistance from the Public Company for Health Emergencies (Empresa Pública de Emergencias Sanitarias (EPES)) in Andalusia during 2012, which served 8 393 159 people. Databases of the National Statistics Institute, Basic Spatial Data of Andalusia and System of Multiterritorial Information of Andalusia were used to retrieve spatial data and population characteristics. Geographic Information System software (QGIS and GeoDA) was used for analysis and linkage across databases. Spatial analyses of geographical location influence in hypoglycemic events were assessed using Moran's I statistics, and linear regressions were used to determine their association with population characteristics.

RESULTS

The EPES attended 1 137 738 calls requesting medical assistance, with a mean hypoglycemia incidence of 95.0±61.6 cases per 100 000 inhabitants. There were significant differences in hypoglycemia incidence between basic healthcare zones attributable to their geographical location in the overall population (Moran's I index 0.122, z-score 7.870, p=0.001), women (Moran's I index 0.088, z-score 6.285, p=0.001), men (Moran's I index 0.076, z-score 4.914, p=0.001) and aged >64 years (Moran's I index 0.147, z-score 9.753, p=0.001). Hypoglycemia incidence was higher within unemployed individuals (β=0.003, p=0.001) and unemployed women (β=0.005, p=0.001), while lower within individuals aged <16 years (β=-0.004, p=0.040), higher academic level (secondary studies) (β=-0.003, p=0.004) and women with secondary studies (β=-0.005, p<0.001). In subjects aged >64 years, lower rate of hypoglycemia was associated with more single-person homes (β=-0.008, p=0.022) and sports facilities (β=-0.342, p=0.012).

CONCLUSIONS

This analysis supports the geographical distribution of hypoglycemia in the overall population, both genders and subjects aged >64 years, which was affected by societal factors such as unemployment, literacy/education, housing and sports facilities. These data can be useful to design specific prevention programs.

Optimizing drug therapy in frail patients with type 2 diabetes mellitus

BACKGROUND

Type 2 diabetes mellitus (T2DM) is closely linked with ageing. In frail diabetic patients, the risks of intensive antidiabetic therapy outweigh the potential benefits.

AIMS

To study the prevalence of T2DM in frail elderly patients, to identify inappropriate prescription (IP) of antidiabetic drugs and to study the relationship between patients' frailty index (FI) with polypharmacy and IP.

METHODS

This was a prospective, descriptive, observational study of elderly patients. Each patient's antidiabetic treatment was analysed by applying the patient-centred prescription model (PCP), which centres therapeutic decisions on the patient's global assessment and individual therapeutic goal.

RESULTS

210 patients with T2DM were included (25.15% prevalence). They were characterised by high multimorbidity and frailty. 93.3% presented polypharmacy and 51% excessive polypharmacy. IP was identified in 66.2% of patients. A statistically significant relationship was found between the progression in FI degree and IP prevalence (p < 0.05. During the admission, drug therapy regimens were modified in 97.1% of cases with IP (n = 136).

DISCUSSION

These results suggest that in clinical practice T2DM treatment is not individualised, but rather is based on the same general recommendations for the population as a whole.

CONCLUSIONS

There is a high prevalence of T2DM in the elderly. As the frailty of patients increases, so does the prevalence of IP. The application of PCP model enables drug therapy optimization in frail patients according to their main therapeutic goal, and contributes to provide clinical evidences on the applicability of a set of knowledge areas from the theoretical framework to the daily clinical practice.

Cost analysis of the flash monitoring system (FreeStyle Libre 2) in adults with type 1 diabetes mellitus

INTRODUCTION

Compare cost of the interstitial liquid glucose flash monitoring (FM) system (FreeStyle Libre 2) versus self-monitoring of blood glucose (SMBG) in adults with type 1 diabetes mellitus (T1DM) in Spain.

RESEARCH DESIGN AND METHODS

A model was developed to estimate, with the perspective of the Spanish health system, the annual costs associated with glucose monitoring and hypoglycemic events management in T1DM population, with multiple insulin daily doses (MDI). According to published evidence, rate of severe hypoglycemia (SHE) of 4.90 episodes per patient-year was applied. Reduction of SHE (58.6%) was modeled associated with FM use. Published rates of hospital care (20.2%) and subsequent admission (16%) were assumed for SHE. The daily consumption of strips and lancets was 9 in patients with SMBG (before and after 4 daily intakes and at bedtime) and 0.5 for FM users (according to IMPACT trial findings). Annual consumption of 26 FM sensors was considered (1 every 14 days). Unit costs (in € of 2019, excluding VAT) were obtained from literature and national databases. Sensitivity analyses (SA) were carried out to evaluate the model robustness.

RESULTS

The total annual cost/patient was €4437 for SMBG and €2526 for FM. The use of FM would be associated with an annual savings in the costs of monitoring and managing hypoglycemic events of €1911 per patient-year. In a hypothetical cohort of 1000 patients with T1DM MDI, FM could avoid in 1 year 4900 SHE, 93 hospitalizations for SHE. In addition, the use of FM would generate total savings of up to €1 910 000 per year. In the SA with alternative hypoglycemia events rates and use of strips and lancets, and including non-SHE episodes, savings from €370 000 to €1 760 000 were observed with FM.

CONCLUSIONS

The use of the FM system to monitor glucose in adults with T1DM treated with MDI, would reduce hypoglycemic events and would result in cost savings for the health system.

The Association Between Poor Glycemic Control and Health Care Costs in People With Diabetes: A Population-Based Study

OBJECTIVE

To analyze the differences in health care costs according to glycemic control in people with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Data on health care resource utilization from 100,391 people with type 2 diabetes were extracted from the electronic database used at the Catalan Health Institute. Multivariate regression models were carried out to test the impact of glycemic control (HbA_1c) on total health care, hospital admission, and medication costs; model 1 adjusted for a variety of covariates, and model 2 also included micro- and macrovascular complications. Glycemic control was classified as good for HbA_1c <7%, fair for ≥7% to <8%, poor for ≥8% to <10%, and very poor for ≥10%.

RESULTS

Mean per patient annual direct medical costs were €3,039 ± SD €6,581. Worse glycemic control was associated with higher total health care costs: compared with good glycemic control, health care costs increased by 18% (€509.82) and 23% (€661.35) in patients with very poor and poor glycemic control, respectively, when unadjusted and by €428.3 and €395.1, respectively, in model 2. Medication costs increased by 12% in patients with fair control and by 28% in those with very poor control (model 2). Patients with poor control had a higher probability of hospitalization than those with good control (5% in model 2) and a greater average cost when hospitalization occurred (€811).

CONCLUSIONS

Poor glycemic control was directly related to higher total health care, hospitalization, and medication costs. Preventive strategies and good glycemic control in people with type 2 diabetes could reduce the economic impact associated with this disease.

Clinical guidelines for type 1 diabetes mellitus with an emphasis on older adults: an Executive Summary

We present a summary of a guideline produced by an international group of experts for managing type 1 diabetes in adults with an emphasis on the special needs of older people with this condition. The rationale for delivering high-quality diabetes care for adults with type 1 diabetes, why it is important to include older people in our considerations, and the key underpinning principles of the guideline are included. The structure of the recommendations given is described and consists of 'general' recommendations followed by 'specific' recommendations according to three categories depending on the characteristics of adults addressed, such as functional level or self-management ability. Recommendations are provided in the areas of: clinical diagnosis, establishing management plans and glucose regulation, diabetes self-management education, nutritional therapy, physical activity, exercise and lifestyle modification, insulin treatments and regimens, use of technology in diabetes management, hypoglycaemia, managing cardiovascular risk, management of microvascular risk, and inpatient management of type 1 diabetes and ketoacidosis.

Direct medical costs in the preceding, event and subsequent years of a first severe hypoglycaemia episode requiring hospitalization: A population-based cohort study

AIMS

We aimed to estimate the use of healthcare services and the direct medical costs accrued by patients with diabetes mellitus (DM) during the year of the first severe hypoglycaemia (SH) event, as well as during the years before and after the event year.

MATERIALS AND METHODS

We analysed a population-based, retrospective cohort including all adults with DM managed in the primary care setting from the Hong Kong Hospital Authority between 2006 and 2013. DM patients for whom SH was first recorded during the designated period were identified and matched to a control group of patients who had not experienced an SH event using the propensity score method. Direct medical costs in the years before, during and after the first SH event were determined by totalling the costs of health services utilized within respective years.

RESULTS

After matching, a total of 22 694 DM patients were divided into the first recorded-SH group (n = 11 347) and the non-SH control group (n = 11 347). Patients for whom SH was first recorded, on average, made 7.85 outpatient clinic visits, made 1.89 emergency visits and spent 17.75 nights hospitalized during the event year. Mean direct medical costs during the event year were 11 751 US$, more than 2-fold that during the preceding year (4846 US$; P < 0.001) and subsequent years (4198-4700 US$; P < 0.001) and was 4.5 times that 2 years before the event (2481 US$; P < 0.001). Incremental costs of SH patients vs matched controls during the event year and the preceding year were 10 873 US$ (P < 0.001) and 3974 US$ (P < 0.001), respectively.

CONCLUSIONS

SH is associated with excessive hospital admission rates and direct medical costs during the event year and, in particular, during the year before as compared to patients who had not experienced an SH event.

Epidemiology, Quality of Life, and Costs Associated with Hypoglycemia in Patients with Diabetes in Spain: A Systematic Literature Review

OBJECTIVE

To assess the burden of hypoglycemia in patients with diabetes mellitus (DM) in Spain, including epidemiological data and information relating to healthcare resource utilization (HRU) and costs, and patients' quality of life (QoL).

METHODS

A systematic literature review (SLR) was conducted to identify studies that included original information on epidemiology, HRU and costs, and/or QoL associated with hypoglycemia in patients with DM in Spain, published in either Spanish or English, between January 2007 and April 2017.

RESULTS

Fifteen articles, involving 14 studies, were identified in the SLR and included in the analysis. The estimated rate of severe hypoglycemia (SH) events per patient per year ranged from 0.90 to 1.50 in patients with type 1 DM (T1DM) and from 0.30 to 0.63 in patients with type 2 DM (T2DM). The data on HRU differed extensively between studies, making it difficult to draw a conclusion. Total costs per SH event ranged from €409.97 in patients with T1DM to €713.10 in patients with DM. Work absence was reported in 11.80-18% of the working patients. Further, patients who experienced hypoglycemic events expressed a higher fear and had a poorer QoL than those who did not report these events.

CONCLUSION

Although the data included in the SLR were difficult to synthesize due to heterogeneity of the study designs and patient characteristics in the 14 studies, our search identified a high burden associated with hypoglycemic events in terms of HRU and costs, and patients' QoL. Further research is recommended to reach a consensus on hypoglycemia definition and study design to provide robust evidence on the burden of hypoglycemia and to accurately weigh the impact of this acute complication in Spain.

Profile of semaglutide in the management of type 2 diabetes: design, development, and place in therapy

Type 2 diabetes mellitus (T2DM) has become one of the leading causes of morbidity and mortality in developed countries. Low efficacy, weight gain, and hypoglycemia are the main pitfalls of previous treatments for T2DM. New therapies have been designed with the aim of improving the results in efficacy and quality of life. Glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1 RA) increase glucose-dependent insulin secretion, decrease gastric emptying, and reduce postprandial glucagon secretion. The last GLP-1 RA approved by the US Food and Drug Administration and European Medicines Agency was semaglutide. This review describes its pharmacology, core clinical data coming from the randomized controlled trials included in the development program, proven cardiovascular benefits, safety issues, and precautions for the use of semaglutide in special populations. Additionally, an overview of the positioning of semaglutide in T2DM therapy and practical issues regarding semaglutide initiation are offered.

Analysis of the characteristics of patients with diabetes mellitus who attend a tertiary hospital emergency department for a hypoglycemic event

INTRODUCTION AND OBJECTIVE

Hypoglycemia associated to insulin or other glucose-lowering agents is one of the most common causes of visits to the emergency department for adverse drug reactions. The study objective was to analyze the characteristics of patients with diabetes mellitus (DM) who attend a tertiary hospital emergency department for a hypoglycemic event.

PATIENTS AND METHODS

A 3-year retrospective analysis was conducted of patients with DM who attended the emergency department of Hospital Universitari de Bellvitge for a hypoglycemic event. An analysis was made of epidemiological and diabetes-related characteristics, prevalence of chronic diabetic complications and other comorbidities, the glucose-lowering treatment and the result of the hypoglycemic episode.

RESULTS

Of the 149 hypoglycemic events analyzed, 81.9% occurred in patients with type 2 DM. Mean age of patients with type 2 DM was 75.4 years. DM duration was longer than 10 years in 69.4% of patients. The prevalence rates of chronic kidney disease and cognitive decline were 38.5% and 19.7% respectively in patients with type 2 DM. Insulin with or without other concomitant glucose-lowering agents was associated to 78.7% of episodes in type 2 DM patients. The remaining 21.3% were associated to oral hypoglycemic agents, mainly glibenclamide. After the event, 13.4% of patients required hospital admission, and in 36.8% of these hypoglycemia was associated to use of glibenclamide.

CONCLUSIONS

A majority of hypoglycemic events occurred in elderly patients with type 2 DM, with a high prevalence of associated comorbidities and treated with insulin and sulfonylureas, particularly glibenclamide.

Levels of serum uric acid at admission for hypoglycaemia predict 1-year mortality

AIMS

Hypoglycaemia represents a critical burden with clinical and social consequences in the management of diabetes. Serum uric acid (SUA) has been associated with cardiovascular diseases (CVD), but no conclusive findings are available nowadays in patients suffering from hypoglycaemia. We investigated whether SUA levels at the time of hypoglycaemia could predict all-cause mortality after 1-year follow-up.

METHODS

In total, 219 patients admitted to the Emergency Department (ED) of Ospedale Policlinico S. Martino of Genoa (Italy) have been enrolled between January 2011 and December 2014. The primary endpoint of the study consisted in determining whether SUA levels at the time of ED admission could predict the occurrence of death after 1 year.

RESULTS

The majority of patients were diabetic, especially type 2. CVD and chronic kidney disease were prevalent comorbidities. By a cut-off value obtained by the receiver operating characteristic curve analysis, a Kaplan-Meier analysis demonstrated that patients with SUA levels > 5.43 mg/dL were more prone to death after 1 year compared to those with lower SUA levels. The risk of death increased with high SUA levels both in the univariate and the multivariate models including estimated glomerular filtration rate, C-reactive protein, type of diabetes, and age-adjusted Charlson comorbidity index.

CONCLUSIONS

SUA could be useful as a predictor of 1-year mortality in hypoglycaemic patients, irrespective of severe comorbidities notably increasing the risk of death in these frail patients.

[Treatment of type 2 diabetes mellitus in elderly patients]

The prevalence of type 2 diabetes mellitus (DM2) increases markedly with age. Antidiabetic treatment and the objectives of glycaemic control in elderly patients with DM2 should be individualised according to their biopsychosocial characteristics. In elderly patients for whom the benefits of intensive antidiabetic treatment are limited, the basic objectives should be to improve the quality of life, preserve functionality and avoid adverse effects, especially hypoglycaemia. Treatment of DM2 in the elderly was the subject of a consensus document published in 2012 and endorsed by several Spanish scientific societies. Since then, new therapeutic groups and evidence have emerged that warrant an update to this consensus document. The present document focuses on the therapeutic aspects of DM2 in elderly patients, understood as being older than 75 years or frail.

Derivation and validation model for hospital hypoglycemia

BACKGROUND

An objective and simple prognostic model for hospitalized patients with hypoglycemia could be helpful in guiding initial intensity of treatment.

METHODS

We carried out a derivation rule for hypoglycemia using data from a nationwide retrospective cohort study of patients with diabetes or hyperglycemia carried out in 2014 (n=839 patients). The rule for hypoglycemia was validated using a second data set from a nationwide retrospective cohort study carried out in 2016 (n=561 patients). We derived our prediction rule using logistic regression with hypoglycemia (glucose less than 70mg/dL) as the primary outcome.

RESULTS

The incidence of hypoglycemia in the derivation cohort was 10.3%. Patient's characteristics independently associated with hypoglycemia included episodes of hypoglycemia during the previous three months (odds ratio [OR]: 6.29, 95% confidence interval [95%CI]: 3.37-11.79, p<0.001) estimated glomerular filtration rate lower than 30mL/min/1.73m² (OR: 2.32, 95%CI: 1.23-4.35, p=0.009), daily insulin dose greater than 0.3units per Kg (OR: 1.74, 95%CI: 1.06-2.85, p=0.028), and days of hospitalization (OR: 1.03, 95%CI: 1.01-1.04, p=0.001). The model showed an area under the curve (AUC): 0.72 (95%CI: 0.66-0.78, p<0.001). The AUC in the validation cohort was: 0.71 (95%CI: 0.63-0.79, p<0.001).

CONCLUSIONS

The rule showed fair accuracy to predict hypoglycemia. Implementation of the rule into computer systems could be used in guiding initial insulin therapy.

Estimating the risk of severe hypoglycemic event related to glucose-lowering treatment among Italian patients with diabetes: the HYPOTHESIS database

The primary objective of this study was to estimate 1) the annual risk of undergoing a severe hypoglycemic event in Italian patients with diabetes and 2) the risk of hospitalization following such event. From the HYPOTHESIS database, powered by 46 emergency departments covering a 12-million-odd population, data were extracted of 1,922 hypoglycemic events occurring in patients with diabetes in 2011. The mean age was 71.5 (standard deviation 16.8) years, 50.1% were men, and blood glucose at the time of the event was 44.2 (26.5) mg/dL. Patients were being treated with insulin alone (55%) or in combination with oral hypoglycemic agents (OHA, 15%), or with OHA alone, either in monotherapy (14%) or in multiple therapy (16%). Comorbidities were recorded in 71.8% of the patients. Based on the rates of glucose-lowering drug use in Italian patients with diabetes, the annual risk of undergoing a serious hypoglycemic event was estimated at 1.27% for subjects treated with insulin alone, the highest (p<0.00001) as compared with insulin + OHA (0.41%) or OHA alone, either in monotherapy or in multiple therapy (0.1% and 0.17%, respectively). The risk of being hospitalized following the hypoglycemic event was the least (27.6%) for subjects treated with insulin alone (p<0.0083). Subjects treated with insulin + OHA showed a lower risk (34.2%) as compared with that for subjects treated with OHA (p<0.02). Death occurs in 7% of hospitalized patients. Older age (p<0.0001) and comorbidities (p<0.0001) were risk factors for hypoglycemia-related hospitalization. Treatments with insulin alone (p<0.005) or in combination (p<0.049) were negatively associated with hospital admission. Severe hypoglycemic events associated with the use of oral glucose-lowering agents carry the highest risk of hospital treatment. As such, they are also likely to generate higher tangible and intangible costs.

A new integrated care pathway for ambulance attended severe hypoglycaemia in the East of England: The Eastern Academic Health Science Network (EAHSN) model

AIMS

We developed a new clinical integrated pathway linking a regional Ambulance Trust with a severe hypoglycaemia (SH) prevention team. We present clinical data from the first 2000 emergency calls taken through this new clinical pathway in the East of England.

METHODS

SH patients attended by Ambulance crew receive written information on SH avoidance, and are contacted for further education through a new regional SH prevention team. All patients are contacted unless they actively decline.

RESULTS

Median age (IQR) was 67 (50-80) years, 23.6% of calls were for patients over 80years old, and patients more than 90years old were more common than 20-25year olds in this population. Most calls were for patients (84.9%) who were insulin treated, even those over 80years (75%). One - third of patients attended after a call were unconscious on attendance. 5.6% of patients in this call population had 3 or more ambulance call outs, and they generated 17.6% of all calls. In total, 728 episodes (36.4%) were repeat calls. Insulin related events were clinically more severe than oral hypoglycaemic related events. Patients conveyed to hospitals (13.8%) were significantly older, with poorer recovery in biochemical hypoglycaemia after ambulance crew attendance. Only 19 (1%) opted out of further contact. Patients were contacted by the SH prevention team after a median 3 (0-6) days. The most common patient self - reported cause for their SH episode was related to perceived errors in insulin management (31.4%).

CONCLUSIONS

This new clinical service is simple, acceptable to patients, and a translatable model for prevention of recurrent SH in this largely elderly insulin treated SH population.

Risk factors and outcome differences in hypoglycaemia-related hospital admissions: A case-control study in England

AIMS

To evaluate risk factors for hospital admissions for hypoglycaemia and compare length of hospitalization, inpatient mortality and hospital readmission between hypoglycaemia- and non-hypoglycaemia-related admissions.

MATERIALS AND METHODS

We used all admissions for hypoglycaemia in individuals with diabetes to English NHS hospital trusts between 2005 and 2014 (101 475 case admissions) and 3 random admissions per case in individuals with diabetes without hypoglycaemia (304 425 control admissions). Risk factors and differences in the 3 outcomes were estimated with logistic and negative binomial regressions.

RESULTS

A U-shaped relationship between age and risk of admission for hypoglycaemia was observed until the age of 85 years; compared to the nadir at 60 years, the risk was progressively higher in younger and older patients and steadily declined after 85 years. Social deprivation (positively) and comorbidities (negatively) were associated with the risk of admission for hypoglycaemia. Compared to Caucasians, other ethnic groups had lower (Bangladeshi, Pakistani, Indians) or higher (Caribbean) risk of admission for hypoglycaemia. Length of hospitalization was 26% shorter while risk of rehospitalization was 65% higher in individuals admitted for hypoglycaemia. Compared to admissions for hypoglycaemia, risk of inpatient mortality was 50% lower for unstable angina but higher for acute myocardial infarction (3 times), acute renal failure (5 times) or pneumonia (8 times).

CONCLUSIONS

Among hospital-admitted individuals with diabetes, age, social deprivation, comorbidities and ethnicity are associated with higher frequency of hospitalization for hypoglycaemia. Admission for hypoglycaemia is associated with a greater risk of readmission, a shorter length of hospitalisation and a generally lower inpatient mortality compared to admissions for other medical conditions. These results could help in identifying at-risk groups to reduce the burden of hospitalization for hypoglycaemia.

The Economic Burden of Insulin-Related Hypoglycemia in Spain

INTRODUCTION

An analysis was conducted to estimate the economic burden of insulin-related hypoglycemia in adults in Spain, derived from a novel concept developed for the UK known as the Local Impact of Hypoglycemia Tool.

METHODS

Costs per severe and non-severe hypoglycemic episode were calculated for patients with type 1 diabetes (T1DM) and type 2 diabetes (T2DM). The costs per episode were applied to the population of adults with T1DM and T2DM using insulin in Spain according to the number of severe and non-severe episodes experienced per year. Costs were calculated using Spanish-specific resource costs and published values for resource utilization, including ambulance, accident and emergency (A&E) department, hospitalization, healthcare professional visits, and extra self-monitoring of blood glucose (SMBG) tests used in the week following the episode. A one-way sensitivity analysis on all model inputs was then performed.

RESULTS

The cost of insulin-related hypoglycemia in Spain is estimated as €662.0 m per year, €292.6 m of which is due to severe episodes and €369.4 m to non-severe episodes. The cost per episode varies from €1.25 for patients with T1DM and €1.48 for patients with T2DM for a non-severe episode where extra SMBG testing after the episode is the only action taken, to €4378.22 for T1DM and €3005.74 for T2DM for a severe episode that was treated in hospital and requires an ambulance, A&E visit, hospitalization, and a diabetes specialist visit. A reduction in severe and non-severe hypoglycemia rates of just 20% could lead to considerable cost savings of €284,925 per 100,000 general population.

CONCLUSION

This analysis highlights the substantial economic burden of hypoglycemia in Spain, and gives budget holders the ability to assess the costs of new treatments or patient education programs in relation to the potential cost savings due to lower hypoglycemia rates.

Incidence, recurrence and cost of hyperglycaemic crises requiring emergency treatment in Andalusia, Spain

AIMS

Hyperglycaemic crises (diabetic ketoacidosis and hyperosmolar hyperglycaemic state) are medical emergencies in people with diabetes. We aimed to determine their incidence, recurrence and economic impact.

METHODS

An observational study of hyperglycaemic crises cases using the database maintained by the out-of-hospital emergency service, the Healthcare Emergency Public Service (EPES) during 2012. The EPES provides emergency medical services to the total population of Andalusia, Spain (8.5 million inhabitants) and records data on the incidence, resource utilization and cost of out-of-hospital medical care. Direct costs were estimated using public prices for health services updated to 2012.

RESULTS

Among 1 137 738 emergency calls requesting medical assistance, 3157 were diagnosed with hyperglycaemic crises by an emergency coordinator, representing 2.9 cases per 1000 persons with diabetes [95% confidence intervals (CI) 2.8 to 3.0]. The incidence of diabetic ketoacidosis was 2.5 cases per 1000 persons with diabetes (95% CI 2.4 to 2.6) and the incidence of hyperosmolar hyperglycaemic state was 0.4 cases per 1000 persons with diabetes (95% CI 0.4 to 0.5). In total, 17.7% (n = 440) of people had one or more hyperglycaemic crisis. The estimated total direct cost was €4 662 151, with a mean direct cost per episode of €1476.8 ± 217.8.

CONCLUSIONS

Hyperglycaemic crises require high resource utilization of emergency medical services and have a significant economic impact on the health system.

Healthcare resource use, direct and indirect costs of hypoglycemia in type 1 and type 2 diabetes, and nationwide projections. Results of the HYPOS-1 study

BACKGROUND AND AIMS

To obtain an accurate picture of the total costs of hypoglycemia, including the indirect costs and comparing the differences between type 1 (T1DM) and type 2 diabetes mellitus (T2DM).

METHODS AND RESULTS

HYPOS-1 was a multicenter, retrospective cohort study which analyzed the data of 2229 consecutive patients seen at 18 diabetes clinics. Data on healthcare resource use and indirect costs by diabetes type were collected via a questionnaire. The domains of inpatient admission and hospital stay, work days lost, and third-party assistance were also explored. Resource utilization was reported as estimated incidence rates (IRs) of hypoglycemic episodes per 100 person-years and estimated costs as IRs per person-years. For every 100 patients with T1DM, 9 emergency room (ER) visits and 6 emergency medical service calls for hypoglycemia were required per year; for every 100 patients with T2DM, 3 ER visits and 1 inpatient admission were required, with over 3 nights spent in hospital. Hypoglycemia led to 58 work days per 100 person-years lost by the patient or a family member in T1DM versus 19 in T2DM. The costs in T1DM totaled €90.99 per person-year and €62.04 in T2DM. Direct and indirect costs making up the total differed by type of diabetes (60% indirect costs in T1DM versus 43% in T2DM). The total cost associated with hypoglycemia in Italy is estimated to be €107 million per year.

CONCLUSIONS

Indirect costs meaningfully contribute to the total costs associated with hypoglycemia. As compared with T1DM, T2DM requires fewer ER visits and incurs lower indirect costs but more frequent hospital use.

Costs associated with emergency care and hospitalization for severe hypoglycemia

BACKGROUND AND AIMS

We aimed to determine the direct economic cost of the management of severe hypoglycemia among people with diabetes in Italy.

METHODS AND RESULTS

Data of cases with an acceptance diagnosis of hypoglycemia between January 2011 and June 2012 were collected in 46 Emergency Departments (EDs). Emergency care costs were computed by estimating the average cost per ambulance service, ED visit and short-term (<24 h) observation period. Hospitalization expenditure was estimated using the average cost reimbursed by the Italian healthcare system for hospital admission per patient with diabetes in a specific hospital ward. We retrieved 3516 hypoglycemic episodes occurring in subjects with diabetes. Half the cases (51.8%) required referral to EDs by means of the emergency ambulance services. A total of 1751 cases (49.8%) received an ED visit followed by discharge; 604 cases (17.2%) received a short-term observation period; 1161 (33.1%) were hospitalized. Unit costs for emergency care management were estimated at €205 for an ambulance call, €23 for an ED visit, and €220 for a short-term observation. The mean hospitalization cost was estimated at €5317; the average cost per each severe hypoglycemic event totaled €1911. From a base case assumption, the total direct cost of severe hypoglycemia in patients with diabetes in Italy was estimated to be approximately €23 million per year.

CONCLUSION

Severe hypoglycemia in patients with diabetes constitutes a remarkable economic burden for national healthcare systems. Measures for preventing hypoglycemia are mandatory in diabetes management programs considering the impact on patients and on health spending.

Incidence and care-related costs of severe hypoglycaemia requiring emergency treatment in Andalusia (Spain): the PAUEPAD project

AIMS

Hypoglycaemia is a serious medical emergency. The need for emergency medical service care and the costs of hypoglycaemic emergencies are not completely known.

METHODS

This was a retrospective observational study using Public Company for Health Emergencies (EPES) data for hypoglycaemia in 2012. The EPES provides emergency medical services to the entire population of Andalusia, Spain (8.5 million people). Data on event type, onsite treatments, emergency room visits or hospitalization were collected. Medical costs were estimated using the public rates for healthcare services.

RESULTS

From a total of 1 137 738 emergency calls that requested medical assistance, 8683 had a primary diagnosis of hypoglycaemia (10.34 per 10 000 person-years). The incidence of severe hypoglycaemic episodes requiring emergency treatment in the estimated population with diabetes was 80 episodes per 10 000 person-years. A total of 7479 episodes (86%) required an emergency team to visit the patient's residence. The majority of cases (64%) were addressed in the residence, although 1784 (21%) cases were transferred to hospital. A total of 5564 events (65%) involved patients aged > 65 years. Overall mortality was 0.32% (28 cases). The total annual cost of attending a hypoglycaemic episode was €6 093 507, leading to an estimated mean direct cost per episode of €702 ± 565. Episodes that required hospital treatment accounted for 49% of the total costs.

CONCLUSIONS

Hypoglycaemia is a common medical emergency that is associated with high emergency medical service utilization, resulting in a significant economic impact on the health system.

Trends in Emergency Department Visit Rates for Hypoglycemia and Hyperglycemic Crisis among Adults with Diabetes, United States, 2006-2011

Background

Despite concerns about hypoglycemia events from overly aggressive glycemic reduction, population trends in hypoglycemia and hyperglycemic crisis incidence are unclear. To address this gap, we examined changes in emergency department (ED) visit rates for hypoglycemia and hyperglycemic crisis 2006–2011.

Methods

Using data from the Nationwide Emergency Department Sample, we estimated the number of ED visits for hypoglycemia and hyperglycemic crisis via ICD-9-CM among adults with diabetes. Using data from the National Health Interview Survey, we estimated the population of adults with diabetes and calculated ED visit rates.

Results

From 2006 to 2011, ED visit rates for hypoglycemia declined by 22% from 1.8 to 1.4 per 100 adults (p = 0.003). The rates decreased in all age groups (all P<0.05) except those aged 18 to 44 years (P = 0.31). Hypoglycemia rates displayed a J-shaped curve across age, with the highest rates among adults aged 75 years or older (P <0.001). ED visit rates for hyperglycemic crisis did not change overall but increased 17% for adults aged 65 to 74 years (P = 0.02) and 29% for women (P = 0.01). Hyperglycemic crisis rates were highest among adults aged 18 to 44 years (P <0.001).

Conclusions

Hypoglycemia rates have declined for all adults but persons aged 18–44 years while rates for hyperglycemic crisis remained stable. Future preventive efforts should target on the susceptible population of adults aged 18 to 44 years and those aged 75 years or older.
