Update on Diabetes in the Elderly and in Nursing Home Residents

Sliding Scale Insulin Use in Nursing Homes Before and After Onset of the COVID-19 Pandemic

OBJECTIVE

To characterize sliding-scale insulin (SSI) use in US nursing homes (NHs) before and after the COVID-19 pandemic.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

A total of 129,829 US NH residents on SSI (01/2018-06/2022) across 12 NH chains with a common electronic health record system.

METHODS

Among all residents with at least 1 administration of SSI documented in the electronic medication administration record, we described resident demographics, frequency of SSI monotherapy vs combination therapy with another diabetes medication, number of daily capillary blood glucose readings ("fingersticks"), and hypoglycemia (capillary blood glucose <70 mg/dL) and hyperglycemia after first SSI use. We used interrupted time series analysis (ITS) with segmented linear regression models to examine whether the monthly prevalence of SSI use changed at and after the onset of the COVID-19 pandemic (March 2020).

RESULTS

There were 129,829 unique NH residents with SSI use [51% women, average age 71.3 (SD 11.7) years]. Of these, 36% of residents received SSI monotherapy and 64% received SSI combination therapy. Residents on SSI received an average of 3.96 (SD 1.41) fingersticks per day. Overall, 26% of SSI users experienced a hypoglycemic event within 30 days of the first SSI dose. The ITS analysis identified a step decrease in the rate of SSI use following the onset of the COVID-19 pandemic (43 fewer SSI users per 1000 insulin users) but no change in overall trend over time from before the onset of the pandemic.

CONCLUSIONS AND IMPLICATIONS

SSI use and fingerstick burden are high in NH residents. Hypoglycemia occurred commonly among residents on SSI. Future research should compare the safety and effectiveness of SSI monotherapy vs other diabetes medication regimens to guide person-centered prescribing decisions in NHs.

Mediation role of anxiety on social support and depression among diabetic patients in elderly caring social organizations in China during COVID-19 pandemic: a cross-sectional study

BACKGROUND

Diabetes has become a prominent global public health problem, which is an important cause of death, disease burden, and medical and health economic burden. Previous studies have reported that majority of persons diagnosed with diabetes later presented with psychological and mental health diseases. The study aimed to explore the mediation role of anxiety on social support and depression among diabetic patents in elderly caring social organizations (SOs).

METHODS

A multi-stage stratified cluster random sampling method was used in this cross-sectional study, and a questionnaire consisting of demographic questionnaire, MSPSS, GAD-7, and CES-D-10 was utilized to gather data. SPSS 22.0 and MPLUS 7.4 were used for statistical analysis. Spearman correlation analysis was employed to investigate correlations of key variables. A generalized linear model was used to exam factors associated with depression. Finally, the mediation effect among study variables was investigated by structural equation modeling (SEM).

RESULTS

The average scores of social support, anxiety, and depression were 58.41 ± 14.67, 2.95 ± 3.95, and 7.24 ± 5.53, respectively. The factors of gender, social support, and anxiety were identified as significantly influential factors related to depression among diabetic patients in elderly caring SOs. The effect of social support on depression was significantly mediated by anxiety (β = -0.467, 95%CI: -0.813 to -0.251). Furthermore, anxiety partially mediated the relationship between family support and depression (β = -0.112, 95%CI: -0.229 to -0.012), and anxiety functioned as a complete mediator in the effect of significant others' support and depression (β = -0.135, 95%CI: -0.282 to -0.024).

CONCLUSIONS

The indirect effect of social support on depression through anxiety among diabetic patients in elderly caring SOs was elucidated. Social support played a key role in maintaining and regulating their mental health, particularly from family and significant others. Social support provided by both family and significant others exerted an important influence on maintaining and regulating their mental health. In light of this pathway, the elderly caring SOs should enhance the magnitude of social support from these two sources, thereby diminishing the likelihood of experiencing anxiety and depression.

The predictive values of admission characteristics for 28-day all-cause mortality in septic patients with diabetes mellitus: a study from the MIMIC database

Background

Septic patients with diabetes mellitus (DM) are more venerable to subsequent complications and the resultant increase in associated mortality. Therefore, it is important to make tailored clinical decisions for this subpopulation at admission.

Method

Data from large-scale real-world databases named the Medical Information Mart for Intensive Care Database (MIMIC) were reviewed. The least absolute selection and shrinkage operator (LASSO) was performed with 10 times cross-validation methods to select the optimal prognostic factors. Multivariate COX regression analysis was conducted to identify the independent prognostic factors and nomogram construction. The nomogram was internally validated via the bootstrapping method and externally validated by the MIMIC III database with receiver operating characteristic (ROC), calibration curves, decision curve analysis (DCA), and Kaplan-Meier curves for robustness check.

Results

A total of 3,291 septic patients with DM were included in this study, 2,227 in the MIMIC IV database and 1,064 in the MIMIC III database, respectively. In the training cohort, the 28-day all-cause mortality rate is 23.9% septic patients with DM. The multivariate Cox regression analysis reveals age (hazard ratio (HR)=1.023, 95%CI: 1.016-1.031, p<0.001), respiratory failure (HR=1.872, 95%CI: 1.554-2.254, p<0.001), Sequential Organ Failure Assessment score (HR=1.056, 95%CI: 1.018-1.094, p=0.004); base excess (HR=0.980, 95%CI: 0.967-0.992, p=0.002), anion gap (HR=1.100, 95%CI: 1.080-1.120, p<0.001), albumin (HR=0.679, 95%CI: 0.574-0.802, p<0.001), international normalized ratio (HR=1.087, 95%CI: 1.027-1.150, p=0.004), red cell distribution width (HR=1.056, 95%CI: 1.021-1.092, p=0.001), temperature (HR=0.857, 95%CI: 0.789-0.932, p<0.001), and glycosylated hemoglobin (HR=1.358, 95%CI: 1.320-1.401, p<0.001) at admission are independent prognostic factors for 28-day all-cause mortality of septic patients with DM. The established nomogram shows satisfied accuracy and clinical utility with AUCs of 0.870 in the internal validation and 0.830 in the external validation cohort as well as 0.820 in the septic shock subpopulation, which is superior to the predictive value of the single SOFA score.

Conclusion

Our results suggest that admission characteristics show an optimal prediction value for short-term mortality in septic patients with DM. The established model can support intensive care unit physicians in making better initial clinical decisions for this subpopulation.

Update on the management of diabetes in long-term care facilities

The number of patients with diabetes is increasing among older adults in the USA, and it is expected to reach 26.7 million by 2050. In parallel, the percentage of older patients with diabetes in long-term care facilities (LTCFs) will also rise. Currently, the majority of LTCF residents are older adults and one-third of them have diabetes. Management of diabetes in LTCF is challenging due to multiple comorbidities and altered nutrition. Few randomized clinical trials have been conducted to determine optimal treatment for diabetes management in older adults in LTCF. The geriatric populations are at risk of hypoglycemia since the majority are treated with insulin and have different levels of functionality and nutritional needs. Effective approaches to avoid hypoglycemia should be implemented in these settings to improve outcome and reduce the economic burden. Newer medication classes might carry less risk of developing hypoglycemia along with the appropriate use of technology, such as the use of continuous glucose monitoring. Practical clinical guidelines for diabetes management including recommendations for prevention and treatment of hypoglycemia are needed to appropriately implement resources in the transition of care plans in this vulnerable population.

Phase angle and diabetes in community-dwelling older adults: cross-sectional analysis from the Malaysian elders longitudinal research (MELoR) study

OBJECTIVE

To evaluate the role of PhA in diabetes in a large population of older adults with a high prevalence of diabetes in order to gain new insights on the potential diagnostic and prognostic role of PhA in individuals with diabetes.

DESIGN

Cross-sectional study.

SETTING

Teaching Hospital.

PARTICIPANTS

1085 individuals aged 55 years or over.

MEASUREMENTS

Phase Angle was obtained using bioimpedance analysis with the Bodystat QuadScan^® 4000. Diabetes mellitus was considered present with fasting hyperglycaemia (serum fasting glucose >6.66 mmol/l), HbA1c > 42 mmol/mol (6.1%), or self-reported Diabetes or the consumption of glucose-lowering agents.

RESULTS

The mean age of the (standard deviation) of the 1,085 participants was 68.11 (7.12) years and 60.7% were women. Among male participants, individuals with PhA within the lowest quartile (PhA ≤4.9) were significantly more likely to have diabetes mellitus [odds Ratio (95% confidence interval, CI), 2.02 (1.17-3.47)] following adjustments for age, body mass index and other comorbidities. The above relationship was attenuated following further adjustment hypoglycaemic medications. Men on oral hypoglycaemic agents had significantly reduced PhA [mean difference (95% CI), -0.44 (-0.67 to -0.22)]. No significant relationship between PhA and diabetes existed among women.

CONCLUSION

The association between lower PhA (≤4.9) in men aged 55 and over and diabetes which is accounted for by oral hypoglycaemic agents. The mechanisms underlying this relationship remain unclear. This relationship should also be evaluated further to determine the potential of PhA as a prognostic tool for diabetes.

Diabetes Management According to Health Status in Older Adults with Type 2 Diabetes Staying in Geriatric Care Facilities

BACKGROUND

About 25% of adults >70 years suffer from type 2 diabetes. Due to the heterogeneity of the geriatric population, guidelines emphasize the need to individualize glycemic goals and simplify treatment strategies with the main focus of avoiding hypoglycemia. The aim of this study was to assess glycemic control in patients with type 2 diabetes in geriatric care facilities based on their individual health status.

METHODS

170 medical records of older adults with type 2 diabetes in geriatric care facilities were retrospectively assessed (64.7% female, age 80 ± 9 years; glycated hemoglobin 6.8% ± 3.6% [51 ± 16 mmol/mol]; body mass index 27.9 ± 5.8 kg/m2). Based on the individual health status, patients were allocated to three groups (healthy n = 27, complex n = 86, and poor n = 57).

RESULTS

The overall blood glucose (BG) value was highest in the poor health group with 188 ± 47 mg/dL (poor) vs 167 ± 42 mg/dL (complex) vs 150 ± 34 mg/dL (healthy). BG values of 1.6% (poor) vs 2.8% (complex) vs 1.5% (healthy) of patients were below 90 mg/dL. 36.8% (poor) vs 23.4% (complex) vs 18.5% (healthy) of patients received insulin as the main diabetes therapy, but of these only 14.3% (poor) vs 20% (complex) vs 40% (healthy) were treated with basal insulin.

CONCLUSIONS

Overall, BG values were higher in the poor and complex health group. There were a few low BG values in all groups. Although recommended by international guidelines, basal insulin therapy with its low complexity and low hypoglycemic risk is still underused, especially in the poor health group. Therefore, simplification of diabetes therapy should be considered further.

Observational study of compliance with infection control practices among healthcare workers in subsidized and private residential care homes

Background

The elderly population in Hong Kong is rapidly growing, and the need for residential care homes (RCHs) is increasing. The risk of being infected with micro-organisms increases among the frail and the vulnerable elderly population as their immunity system begins to deteriorate. Furthermore, the residents in RCHs are at high risk of healthcare-associated infections (HAIs) due to the confined living environments and individual co-morbidities. In relation to this, infection control practice (ICP) is considered a crucial and effective approach in preventing HAIs. This study aimed to observe the daily ICP of healthcare workers in RCH settings.

Methods

An observational study was conducted to observe daily ICP among healthcare workers in private and subsidized RCHs. Each RCH was separated into different units based on the location (common area and bedroom area) and nature of residents for successive days. The ICP episodes were observed until 200 opportunities in each unit. The ICP episodes were recorded by an electronic tool called “eRub,” which is an ICP checklist based on international guidelines.

Results

The most frequent observed ICP episodes were hand hygiene (n = 1053), the use of gloves (n = 1053) and respiratory protection (n = 1053). The overall compliance of hand hygiene was poor, with only 15% of participants performing this during the “five moments for hand hygiene.” Furthermore, the observations showed that 77.9% improperly performed the use of gloves, and 31.8% failed to wear a mask during the care provision for the elderly. However, the results showed that most healthcare workers can wear the mask in a proper way when they should. Generally, the personal care workers were the worst in terms of hand hygiene and use of gloves compared with the other types of healthcare workers.

Conclusions

Despite the fact that the practice of hand hygiene, the use of gloves, and respiratory protection were the important elements of ICP, overall compliance to these elements was still poor. Personal care workers had the most frequent contact with the residents, but they had the worst compliance rate. Hence, continued monitoring and training among healthcare workers is needed, particularly personal care workers, in this healthcare service setting.

Challenges and Strategies for Managing Diabetes in the Elderly in Long-Term Care Settings

Diabetes affects a large number of patients in the long-term care (LTC) setting, and their care is often complicated because of multimorbidity, diabetes-related complications, disability, dependency on caregivers, and geriatric syndromes, including frailty and cognitive impairment. This population includes patients receiving short-term rehabilitation in skilled nursing facilities, those who are residents in LTC facilities, and those receiving palliative or end-of-life care. An individualized approach to care based on clinical complexity, diabetes trajectory, and patients' preferences and goals is required. Such patients may experience one or more transitions of care and decline in condition. They are also prone to adverse drug events, cardiovascular events, and hypoglycemia. Facility-related challenges include varying staff competencies and practitioner preferences, inconsistent interdisciplinary communication, overly complex medication regimens, and poorly implemented care transitions.

Efficacy and safety of linagliptin to improve glucose control in older people with type 2 diabetes on stable insulin therapy: A randomized trial

AIM

To assess the addition of linagliptin as an alternative to insulin uptitration in older people with type 2 diabetes on stable insulin therapy.

MATERIALS AND METHODS

This phase 4, randomized, multicentre, double-blinded, placebo-controlled, 24-week study recruited individuals on stable insulin, with baseline HbA1c 7.0%-10.0%, aged ≥60 years and body mass index ≤45 kg/m² . HbA1c and fasting plasma glucose were measured at study visits, and participants assessed glycaemic control with a self-monitoring blood glucose device. Adverse events (AEs) were reported during the study.

RESULTS

Three hundred and two participants were randomized 1:1 to linagliptin 5 mg qd and placebo, with one third of patients from Japan. Study population age and HbA1c (baseline mean ± SD) were 72.4 ± 5.4 years and 8.2 ± 0.8%, respectively; ~80% of participants were aged ≥70 years; 80% had macrovascular complications, one third had a baseline estimated glomerular filtration rate <60 mL/min/1.73 m² ; and half had been diagnosed with diabetes for >15 years. Linagliptin significantly improved glucose control at 24 weeks (HbA1c-adjusted mean change vs. placebo: -0.63%; P <0.0001) and the probability of achieving predefined HbA1c targets without hypoglycaemia (HbA1c <8.0%: OR 2.02; P <0.05 and HbA1c <7.0%: OR 2.44; P <0.01). Linagliptin versus placebo was well tolerated, with similar incidences of AEs, including clinically important hypoglycaemia (blood glucose <54 mg/dL) or severe hypoglycaemia.

CONCLUSIONS

Addition of linagliptin improves glucose control without an excess of hypoglycaemia in older patients with type 2 diabetes on stable insulin therapy.

Diabetes and Aging: From Treatment Goals to Pharmacologic Therapy

Diabetes is becoming one of the most widespread health burning problems in the elderly. Worldwide prevalence of diabetes among subjects over 65 years was 123 million in 2017, a number that is expected to double in 2045. Old patients with diabetes have a higher risk of common geriatric syndromes, including frailty, cognitive impairment and dementia, urinary incontinence, traumatic falls and fractures, disability, side effects of polypharmacy, which have an important impact on quality of life and may interfere with anti-diabetic treatment. Because of all these factors, clinical management of type 2 diabetes in elderly patients currently represents a real challenge for the physician. Actually, the optimal glycemic target to achieve for elderly diabetic patients is still a matter of debate. The American Diabetes Association suggests a HbA1c goal <7.5% for older adults with intact cognitive and functional status, whereas, the American Association of Clinical Endocrinologists (AACE) recommends HbA1c levels of 6.5% or lower as long as it can be achieved safely, with a less stringent target (>6.5%) for patients with concurrent serious illness and at high risk of hypoglycemia. By contrast, the American College of Physicians (ACP) suggests more conservative goals (HbA1c levels between 7 and 8%) for most older patients, and a less intense pharmacotherapy, when HbA1C levels are ≤6.5%. Management of glycemic goals and antihyperglycemic treatment has to be individualized in accordance to medical history and comorbidities, giving preference to drugs that are associated with low risk of hypoglycemia. Antihyperglycemic agents considered safe and effective for type 2 diabetic older patients include: metformin (the first-line agent), pioglitazone, dipeptidyl peptidase 4 inhibitors, glucagon-like peptide 1 receptor agonists. Insulin secretagogue agents have to be used with caution because of their significant hypoglycemic risk; if used, short-acting sulfonylureas, as gliclazide, or glinides as repaglinide, should be preferred. When using complex insulin regimen in old people with diabetes, attention should be paid for the risk of hypoglycemia. In this paper we aim to review and discuss the best glycemic targets as well as the best treatment choices for older people with type 2 diabetes based on current international guidelines.

Patient safety culture in nursing homes - a cross-sectional study among nurses and nursing aides caring for residents with diabetes

Background

Due to the high morbidity and disability level among diabetes patients in nursing homes, the conditions for caregivers are exceedingly complex and challenging. The patient safety culture in nursing homes should be evaluated in order to improve patient safety and the quality of care. Thus, the aim of this study was to examine the perceptions of patient safety culture of nursing personnel in nursing homes, and its associations with the participants’ (i) profession, (ii) education, (iii) specific knowledge related to their own residents with diabetes, and (iv) familiarity with clinical diabetes guidelines for older people.

Methods

Cross-sectional survey design. The study included 89 nursing home personnel (38 registered nurses and 51 nurse aides), 25 (28%) with advanced education, at two nursing homes. We collected self-reported questionnaire data on age, profession, education and work experience, diabetes knowledge and familiarity with diabetes guidelines. In addition, we applied the Nursing Home Survey on Patient Safety Culture instrument, with 42 items and 12 dimensions.

Results

In general, those with advanced education scored higher in all patient safety culture dimensions than those without, however statistically significant only for the dimensions “teamwork” (mean score 81.7 and 67.7, p = 0.042) and “overall perceptions of resident safety” (mean score 90.0 and 74.3, p = 0.016). Nursing personnel who were familiar with diabetes guidelines for older people had more positive perceptions in key areas of patient safety culture, than those without familiarity with the guidelines.

Conclusions

The findings from this study show that advanced education and familiarity with current diabetes guidelines was related to adequate evaluations on essential areas of patient safety culture in nursing homes.

[Assessment of hypoglycemic status among hospitalized elderly patients with type 2 diabetes]

OBJECTIVE

To investigate the hypoglycemic characteristics of hospitalized elderly patients with type 2 diabetes mellitus (T2DM).

METHODS

From January, 2014 to December, 2015, the data of 58 565 blood measurements using a standard blood glucose monitoring system (BGMS) were collected from 1187 cases of patients with type 2 diabetes during hospitalization in the Department of Endocrinology, Guangdong General Hospital (Guangzhou, China). Stratified analyses were conducted by dividing the patients into 3 age groups, namely <45 years group (128 cases), 45-64 years group (594 cases), and ≥65 years group (465 cases). The incidence and time distribution of hypoglycemia in these patients were compared among the 3 age groups.

RESULTS

The risk of hypoglycemia increased with age. Compared with those below 45 years of age, the patients beyond or equal to 65 years had a significantly increased hypoglycemic density (0.95% vs 0.40%, P<0.001), a higher proportion of patients with hypoglycemia (28.17% vs 10.94%, P<0.001), and greater patient-days with hypoglycemia (4.48% vs 1.76%, P<0.001). In the elderly patients, hypoglycemia occurred most frequently before dawn, at which time the hypoglycemic density was 2.66% in patients ≥65 years of age, significantly higher than that in patients below 45 years (1.09%, P<0.05) and between 45 and 64 years (1.90%, P<0.05); the proportion of patients with hypoglycemia was also significantly higher in the elderly patients (14.57%) than in those below 45 years (3.77%, P<0.02) and between 45 and 64 years (9.42%, P<0.02). The proportion of patients with recurrent hypoglycemia (≥2 times) was significantly higher in patients ≥65 years (13.33%) than in younger patients (2.34% in <45 years group and 9.43% in 45-64 years group, P<0.05).

CONCLUSION

The hypoglycemic risk in hospitalized elderly patients with T2DM is significantly higher than that in younger patients, especially before dawn and in terms of recurrent hypoglycemia. Clinicians should develop differential blood glucose monitoring and management strategies for these elderly patients to improve the clinical safety.

A Randomized Controlled Study Comparing a DPP4 Inhibitor (Linagliptin) and Basal Insulin (Glargine) in Patients With Type 2 Diabetes in Long-term Care and Skilled Nursing Facilities: Linagliptin-LTC Trial

OBJECTIVES

Safe and easily implemented treatment regimens are needed for the management of patients with type 2 diabetes mellitus (T2DM) in long-term care (LTC) and skilled nursing facilities.

DESIGN

This 6-month open-label randomized controlled trial compared the efficacy and safety of a DPP4 inhibitor (linagliptin) and basal insulin (glargine) in LTC residents with T2DM.

SETTINGS

Three LTC institutions affiliated with a community safety-net hospital, US Department of Veterans Affairs and Emory Healthcare System in Atlanta, Georgia.

PARTICIPANTS

A total of 140 residents with T2DM treated with oral antidiabetic agents or low-dose insulin (≤0.1 U/kg/d), with fasting or premeal blood glucose (BG) > 180 mg/dL and/or HbA1c >7.5%.

INTERVENTION

Baseline antidiabetic therapy, except metformin, was discontinued on trial entry. Residents were treated with linagliptin 5 mg/d (n = 67) or glargine at a starting dose of 0.1 U/kg/d (n = 73). Both groups received supplemental rapid-acting insulin before meals for BG > 200 mg/dL.

MEASUREMENTS

Primary outcome was mean difference in daily BG between groups. Main secondary endpoints included differences in frequency of hypoglycemia, glycosylated hemoglobin (HbA1c), complications, emergency department visits, and hospital transfers.

RESULTS

Treatment with linagliptin resulted in no significant differences in mean daily BG (146 ± 34 mg/dL vs. 157 ± 36 mg/dL, P = .07) compared to glargine. Linagliptin treatment resulted in fewer mild hypoglycemic events <70 mg/dL (3% vs. 37%, P < .001), but there were no differences in BG < 54 mg/dL (P = .06) or <40 mg/dL (P = .05) compared to glargine. There were no significant between-group differences in HbA1c, length of stay, complications, emergency department visits, or hospitalizations.

CONCLUSION

Treatment with linagliptin resulted in noninferior glycemic control and in significantly lower risk of hypoglycemia compared to insulin glargine in long-term care and skilled nursing facility residents with type 2 diabetes.

HYPERGLYCEMIA AND HYPOGLYCEMIA IN PATIENTS WITH DIABETES IN SKILLED NURSING FACILITIES

OBJECTIVE

Endocrinologists are faced with a growing elderly patient population with diabetes mellitus (DM), some of whom are in skilled nursing facilities (SNFs). Efforts at managing their DM is hampered by concerns for hypoglycemia. This study aimed to determine the frequency of hypo- and hyperglycemia in SNFs, and associated factors.

METHODS

We reviewed medical records of 200 consecutive residents admitted to two SNFs in the Cleveland area in 2014 with documented DM, aged ≥65 years. Data collected included blood glucose (BG) levels and DM regimens. Frequency of hyper- and hypoglycemic events was noted. Since patients had different frequencies of BG checks, event-days were calculated.

RESULTS

Mean age, BG, and glycated hemoglobin (±SD) were as follows: 80.2 ± 8.2 years, 172.4 ± 40.3 mg/dL, and 7.5 ± 1.9% (59 mmol/mol), respectively. Seventy-one percent were on insulin alone, 15.5% on insulin and oral diabetes agents, and 13.5% on oral diabetes agent on admission. Patients with at least one event were as follows: 38% hypoglycemia, 3.5% severe hypoglycemia, 90.5% hyperglycemia, and 15% severe hyperglycemia. Event-days were: 3.4% hypoglycemia and 52.4% hyperglycemia. Risk of hypoglycemia was highest with concomitant sulfonylurea and prandial or sliding-scale insulin. Hyperglycemia risk was high in basal insulin-containing regimens.

CONCLUSION

Hypoglycemia was seen in one-third of patients, and hyperglycemia was common despite insulin use. Concomitant use of sulfonylurea and prandial or sliding-scale insulin is best avoided in this fragile population with hypo- and hyperglycemia.

Hospitalization of elderly diabetic patients: characteristics, reasons for admission, and gender differences

Background

Understanding the differences in characteristics, gender, and common causes for admission in hospitalized elderly diabetic patients provides a theoretical basis for their successful management. This study explored the reasons and gender differences in hospitalizations of elderly patients with diabetes mellitus.

Methods

Patients aged ≥60 years who had received a diagnosis of diabetes by the time of discharge, from 1 January 2011 to 1 January 2014, were retrospectively enrolled. Hospitalization data of the patients were collected, and reasons for hospitalization were analyzed based on chief complaints and principle diagnosis.

Results

The most frequent reasons stated for admission were related to the chronic complications of diabetes (42.1 %), seconded by hyperglycemia (26.4 %) and infection (15.7 %). Ketonuria, ketonemia, or diabetic ketoacidosis was more commonly seen in women than men, whereas diabetic nephropathy and neoplasms were more frequently found in men than women. Regarding infection as a cause of hospitalization, the 4 main types were respiratory tract (44.5 %), urinary tract (20.3 %), gastrointestinal (14.8 %), and skin and soft tissue (10.9 %). Respiratory tract infection was significantly more common in men (61.4 %) than women (31 %, P = 0.001), whereas urinary tract infection was more frequent in women (29.6 %) than men (8.8 %, P = 0.004).

Conclusion

The most frequent reasons for hospital admission in elderly diabetic patients were chronic complications of diabetes, hyperglycemia, and infection. Men and women differed in reasons for hospital admission.

Delivery of Care to Nursing Home Residents With Diabetes: Results From the SHELTER Study

OBJECTIVES

To describe health care and preventive service provision to nursing home (NH) residents with diabetes mellitus (DM) and to analyze factors determining use of selected services.

DESIGN

In the period between 2009 and 2011, the Services and Health for Elderly in Long TERm care (SHELTER) project, a 12-month prospective cohort study, was conducted to assess 4037 NH residents aged 60 years and older residing in 59 NHs in 7 European countries and Israel.

METHODS

The InterRAI tool for long-term care facilities was used to assess care needs and provided health care services. Descriptive statistics and multivariate logistic regression were applied to describe differences between NH residents with (DR) and without DM (non-DR), and to find factors determining use of services and care provided to both groups.

RESULTS

DR more often than non-DR were hospitalized (18.2% vs 14.3%) and required rehabilitation (23.8% vs 18.2%) or clinically complex care (15.9% vs 13.7%). They also more frequently received a repositioning program (26.8% vs 22.7%), a wound care (15.1% vs 9.8%), and some preventive services as yearly eye examination (41.0% vs 35.9%), pneumococcal vaccination (33.5% vs 26.6%), mammography in women (12.1% vs 7.4%), and colonoscopy (5.6% vs 3.6%). Yet, rates of some of them (mammography, colonoscopy, hearing and dental examinations) were very low in both study cohorts with exception of annual influenza vaccination (82.1%) and yearly blood pressure checkup (95.0%). Interestingly, DM enhanced odds only for mammography [odds ratio (OR) 1.55, 95% confidence interval [CI] 1.15-2.09, P = .004) and eye examination (OR 1.21, 95% CI 1.03-1.42; P = .018).

CONCLUSIONS

DR more frequently receive care related to DM clinical complexity; nevertheless, the recommended frequency of preventive procedures is not met both in DR and non-DR.

Management of Diabetes in Long-term Care and Skilled Nursing Facilities: A Position Statement of the American Diabetes Association

Diabetes is more common in older adults, has a high prevalence in long-term care (LTC) facilities, and is associated with significant disease burden and higher cost. The heterogeneity of this population with regard to comorbidities and overall health status is critical to establishing personalized goals and treatments for diabetes. The risk of hypoglycemia is the most important factor in determining glycemic goals due to the catastrophic consequences in this population. Simplified treatment regimens are preferred, and the sole use of sliding scale insulin (SSI) should be avoided. This position statement provides a classification system for older adults in LTC settings, describes how diabetes goals and management should be tailored based on comorbidities, delineates key issues to consider when using glucose-lowering agents in this population, and provides recommendations on how to replace SSI in LTC facilities. As these patients transition from one setting to another, or from one provider to another, their risk for adverse events increases. Strategies are presented to reduce these risks and ensure safe transitions. This article addresses diabetes management at end of life and in those receiving palliative and hospice care. The integration of diabetes management into LTC facilities is important and requires an interprofessional team approach. To facilitate this approach, acceptance by administrative personnel is needed, as are protocols and possibly system changes. It is important for clinicians to understand the characteristics, challenges, and barriers related to the older population living in LTC facilities as well as the proper functioning of the facilities themselves. Once these challenges are identified, individualized approaches can be designed to improve diabetes management while lowering the risk of hypoglycemia and ultimately improving quality of life.

Tighter glycemic control is associated with ADL physical dependency losses in older patients using sulfonylureas or mitiglinides: Results from the DIMORA study

BACKGROUND

There is growing evidence that tight glycemic control may be more harmful than beneficial in older persons with Type 2 diabetes (T2DM). It remains controversial if tight glycemic control (lower glycated hemoglobin A1c (A1c)) is associated with functional impairments in older frail patients with T2DM. We explored associations between A1c and losses in Activities of Daily Living (ADLs) in diabetic nursing home (NH) patients and tested for differences according to anti-diabetic treatment: diet, anti-diabetic oral drug (AOD), insulin, combined insulin+AOD.

METHODS

We conducted a cross-sectional study on 1845 older NH patients with T2DM from 150 sites across Italy. Complete evaluations on ADLs, glycemic control, anti-diabetic treatments, comorbidities, and clinical data were recorded. ANOVA was applied to compare clinical characteristics across A1c tertiles. Multivariate regression models evaluated associations between A1c and ADL losses.

RESULTS

Patients had a mean age [SD]=82 [8] years; BMI=25.5 kg/m(2) [4.7]; Fasting Plasma Glucose (FPG)=7.4 [3.0] mmol/l; Post-prandial glucose (PPG)=10.3 [3.6] mmol/l; A1c=7.0% (54 mmol/mol), ADL losses=3.7 [1.8]. Compared to higher A1c tertiles, patients in the lower tertile had greater ADL losses, were more likely to use AODs, while less likely to use insulin or insulin+AOD. After adjusting for multiple confounders, impairments in ADLs were associated with tighter A1c levels (B=-0.014; p=0.002). Regression models according to anti-diabetic treatment showed that tighter A1c levels continued as independent determinants of ADL losses in patients using AODs (B=-0.023; p=0.001), particularly in those using sulfonylureas (B=-0.043; p<0.001) or mitiglinides (B=-0.044; p=0.050).

CONCLUSIONS

Tighter glycemic control was associated with ADL physical dependency losses, especially in those using sulfonylureas and mitiglinides.

Sliding Scale Insulin vs Basal-Bolus Insulin Therapy in Long-Term Care: A 21-Day Randomized Controlled Trial Comparing Efficacy, Safety and Feasibility

INTRODUCTION

Sliding scale insulin (SSI) therapy remains a common means of insulin therapy in long-term care (LTC) for the management of type 2 diabetes mellitus, despite current recommendations not supportive of the form of therapy today. Lack of randomized trial data on the efficacy and safety of basal-bolus insulin (B-BI) therapy in nursing home residents may have precluded this form of insulin administration in the LTC setting. Our study is a comparison of the efficacy of SSI (control) and B-BI (intervention) therapies during a 21-day intervention trial in older nursing home residents.

METHODS

Fourteen LTC facilities in the US participated; 110 residents with type 2 diabetes volunteered to participate; 35 failed inclusion criteria, 75 signed informed written consent, and 11 were discharged to home/hospital or withdrew consent; data from 64 participants are reported. Recent fasting blood glucose (FBG), hemoglobin A1c, and chemistries were obtained. Four glucose readings (prior to breakfast, lunch, dinner, and bedtime), oral antiglycemic drug, and insulin doses and changes, and all adverse events/serious adverse events, both those related to glucose control [hypoglycemic (<70 mg/dL) and hyperglycemic (>200 mg/dL) episodes] and those unrelated, were recorded daily. Patients were randomized to either remain on SSI or be shifted to the B-BI group.

RESULTS

Nursing home residents 80 ± 8 (standard deviation) years, 66% female participated; Control and Intervention participants had similar age, gender, race distributions, comorbidity, and 3-day average pretrial FBG levels (all P > .05). At study end, B-BI volunteers had significantly lower 3-day average FBG levels vs pretrial (P = .0231) while SSI participants had no change in 3-day average FBG (P > .05). During the trial, participants from both groups had similar rates of hypoglycemia, hyperglycemia, other adverse events, and hospitalizations (serious adverse events) unrelated to glucose control (all P > .05).

CONCLUSIONS

B-BI therapy produced significantly lower average FBG levels after 21 days compared with SSI therapy; both groups had similar rates of hypo- and hyperglycemia. Switching to B-BI therapy is feasible, safe, and effective in the LTC setting.

Diabetes self-care and the older adult

The prevalence of diabetes is highest in older adults, a population that is increasing. Diabetes self-care is complex with important recommendations for nutrition, physical activity, checking glucose levels, and taking medication. Older adults with diabetes have unique issues that impact self-care. As people age, their health status, support systems, physical and mental abilities, and nutritional requirements change. Furthermore, comorbidities, complications, and polypharmacy complicate diabetes self-care. Depression is also more common among the elderly and may lead to deterioration in self-care behaviors. Because of concerns about cognitive deficits and multiple comorbidities, adults older than 65 years are often excluded from research trials. Thus, little clinical evidence is available and the most appropriate treatment approaches and how to best support older patients' self-care efforts are unclear. This review summarizes the current literature, research findings, and expert and consensus recommendations with their rationales.

Drug treatment for diabetes in nursing home residents

AIMS

The aim of this study was to describe drug treatment for diabetes in a large sample of nursing home residents and to compare subjects' health outcomes according to the anti-diabetic agents used.

METHODS

The cross-sectional data of 6275 residents [average age 86 years (± 8.2); 73.7% women] from 175 nursing homes in France were analysed. Participants were divided into one of the following four groups: diabetes non-drug treatment, diabetes hypoglycaemic (e.g. insulins, sulphonylurea) treatment, diabetes non-hypoglycaemic (e.g. metformin) treatment and no diabetes. Group comparisons were made on functional ability (activities of daily living score) and on the prevalence of the following variables (yes vs. no): emergency department visits, falls and fractures.

RESULTS

Of the participants, 1076 (17.1%) had diabetes: 222 participants in the non-drug treatment group, 722 in the hypoglycaemic group and 132 in the non-hypoglycaemic group. The remaining 5199 participants made up the group without diabetes. Insulin and metformin were used by 549 and 185 participants, respectively. Activities of daily living scores differed across the four groups, with those in the non-drug treatment group being the most disabled. Adjusted multivariate analyses showed that, compared with the group without diabetes, those in the hypoglycaemic group had a higher probability of emergency department visits (odds ratio 1.26, 95% CI 1.03-1.54) and increased the incidence rate ratios (1.02, 95% CI 1.00-1.04) of disability (activities of daily living score), whereas the non-hypoglycaemic group was not significantly associated with these outcomes.

CONCLUSIONS

The use of hypoglycaemic drugs was associated with poor health outcomes in nursing home residents. Therefore, more attention must be paid to adapting anti-diabetic treatment in this complex population.

Diabetes in long-term care facilities

With the aging of the population and longer life expectancies, the prevalence of population with multiple chronic medical conditions has increased. Difficulty managing these conditions as people age (because of changes in physical, functional, or cognitive abilities and the complexity of many treatment regimens), has led to more individuals with multiple medical conditions admitted to the long-term care facilities. Older adults with diabetes residing in the long-term facilities represent the most vulnerable of this cohort. Studies that specifically target diabetes management in older population are lacking and those that target diabetes management in the long-term care facilities are even fewer. The lack of knowledge regarding the care of the elderly residing in long-term care with diabetes may lead to treatment failure and higher risk of hyperglycemia, as well as hypoglycemia. In aging populations, hypoglycemia has the potential for catastrophic consequences. To avoid this, the management of older population with diabetes and other medical comorbidities residing in long-term care facilities requires a more holistic approach compared with focusing on individual chronic disease goal achievement.

Management of Type 1 Diabetes in Older Adults

Older adults with type 1 diabetes are at high risk for severe hypoglycemia and may have serious comorbid conditions. Problems with cognition, mobility, dexterity, vision, hearing, depression, and chronic pain interfere with the ability to follow complex insulin regimens. With the development of geriatric syndromes, unpredictable eating, and frailty, treatment regimens must be modified with the goal of minimizing hypoglycemia and severe hyperglycemia and maximizing quality of life.

Cognition and nutrition

PURPOSE OF REVIEW

Aging is associated with a decline in cognition. This review examines the available data on the effects of nutrition on cognitive impairment. It also explores the mechanism(s) by which food may enhance memory.

RECENT FINDINGS

An increasing body of evidence has supported the role of the Mediterranean diet and extra-virgin olive oil in protecting cognition. A number of nutritional formulations to improve deteriorating memory are being studied. Undernutrition is associated with cognitive decline. Hyperglycemia and hypertriglyceridemia cause cognitive impairment.

SUMMARY

There are increasing data to support the role of nutrition in maintaining cognition.

Prevalence, quality of care, and complications in long term care residents with diabetes: a multicenter observational study

BACKGROUND

Few studies have reported on the quality of diabetes care and glycemic control adjusted for medication use in long term care (LTC) facilities.

METHODS

This observational study analyzed diabetes prevalence and management and the impact of glycemic control on clinical outcome in elderly subjects admitted to 3 community LTC facilities.

RESULTS

Among 1409 LTC residents (age 79.7 ± 12 years), the prevalence of diabetes was 34.2%. Subjects with diabetes were either on no pharmacological agents (10%) or were treated with sliding scale regular insulin (SSI, 25%), oral antidiabetic drugs (OAD, 5%), insulin (34%), or with combination of OAD and insulin (26%). Patients with diabetes had a mean daily BG of 156 ± 39 mg/dL and a mean admission HbA1c of 6.7% ± 1.1%. Compared with nondiabetes, residents with diabetes had higher number of complications (54% vs 45%, P < .001), infections (26% vs 21%, P = .036), emergency room (ER) and hospital transfers (37% vs 30%, P = .003), but similar mortality (15% vs 14%, P = .56). A total of 43% of residents with diabetes had a BG less than 70 mg/dL, and those with hypoglycemia had longer median length of stay (LOS, 52 vs 29 days, P < .001), more ER or hospital transfers (56% vs 69%, P = .005), and mortality (20% vs 10%, P = .002) compared with residents without hypoglycemia.

CONCLUSION

Diabetes is common in LTC residents and is associated with higher resource utilization and complications. Hypoglycemia is common and is associated with increased need of emergency room visits and hospitalization and higher mortality. Our findings emphasize the need for randomized trials evaluating the impact of different approaches to glycemic management on clinical outcome in LTC residents with diabetes.

Use of telemedicine to improve glycemic management in a skilled nursing facility: a pilot study

The objective of this study was to evaluate the feasibility of using telemedicine to improve glycemic control (reduce episodes of hypoglycemia and severe hyperglycemia) for residents with diabetes in a skilled nursing facility. This randomized pilot study enrolled residents with diabetes (n=23; mean age, 83 years; 91% insulin-treated) and compared usual care (control; n=11) with usual care plus weekly/biweekly teleconsultations with an endocrinologist (n=12) for up to 6 months. A nurse and dietitian from the skilled nursing facility were at all televisits. Residents who were able and willing attended the televisits. Family members were also invited and occasionally were present. The endocrinologist reviewed glucose levels from point-of-care glucose meter downloads, dietary intake, medications, and medical status and recommended changes in glycemic therapy as needed. Measurements included glucose levels from point-of-care glucose meter downloads, hemoglobin A1c (A1c) levels, and a nurse satisfaction survey. Results showed that 7 of 10 insulin-treated intervention subjects had basal doses reduced (18-69%) compared with 2 of 11 control subjects (reduced 10% and 25%, respectively). There was a decrease in percentage of intervention participants with episodes of hypoglycemia (<80 mg/dL) over the previous month from baseline (42%) to end of study (22%) versus a rise in the control group (from 36% to 45%) and less hyperglycemia (>400 mg/dL) (intervention, from 33% to 22%; control, from 22% to 55%). There were no end-of-study A1c values >8.0% in the intervention group versus 44% in controls. Nursing staff at the skilled nursing facility expressed high satisfaction. Results suggest that telemedicine diabetes consultations to skilled nursing facilities can improve glycemic management.

Evaluation of an intra-institutional diabetes disease management program for the glycemic control of elderly long-term care diabetic patients

AIM

Increasing numbers of nursing home elderly patients suffer from diabetes requiring individually optimized glycemic control. This is a complicated challenge because of their high comorbidity level, and heterogeneous and changing eating status varying from independent to dysphagia and enteral feeding. In order to cope with these complex needs, we developed and implemented a diabetes disease management program. The purpose of the present study was to evaluate this program.

METHODS

We used the point prevalence approach by checking for fasting blood glucose, glycated hemoglobin and other routine biochemical tests. Eating status was evaluated by the Functional Outcome Swallowing Scale. Details about the diabetes disease management program are given in the text.

RESULTS

A total of 86 (36%) of the 234 patients on the study day were diabetics. Of these, 80 were eligible for the study. Their mean fasting blood glucose was 143.1 ± 60.6 mg/dL. The mean glycated hemoglobin level was 7.23 ± 1.39%.

CONCLUSION

No case of hypoglycemia was detected on the examination day, or during the preceding 3 weeks. No significant difference was found among the different Functional Outcome Swallowing Scale categories. These results are within satisfactory range for this category of patients suggesting that our diabetes disease management program contributes to a better glycemic control.
