RESUMO

OBJECTIVE: To examine the effects of insulin-adjunctive therapy with a sodium-glucose cotransporter 2 (SGLT2) inhibitor and a glucagon receptor antagonist (GRA) on glycemia, insulin use, and ketogenesis during insulinopenia in type 1 diabetes. RESEARCH DESIGN AND METHODS: In a randomized, double-blind, placebo-controlled, crossover trial we assessed the effects of adjunctive SGLT2 inhibitor therapy (dapagliflozin 10 mg daily) alone and in combination with the GRA volagidemab (70 mg weekly) in 12 adults with type 1 diabetes. Continuous glucose monitoring, insulin dosing, and insulin withdrawal tests (IWT) for measurement of glucose and ketogenesis during insulinopenia were completed during insulin-only (Baseline), SGLT2 inhibitor, and combination (SGLT2 inhibitor + GRA) therapy periods. RESULTS: Average glucose and percent time with glucose in range (70-180 mg/dL) improved with combination therapy versus Baseline and SGLT2 inhibitor (131 vs. 150 and 138 mg/dL [P < 0.001 and P = 0.01] and 86% vs. 70% and 78% [P < 0.001 and P = 0.03], respectively) without increased hypoglycemia. Total daily insulin use decreased with combination therapy versus Baseline and SGLT2 inhibitor (0.41 vs. 0.56 and 0.52 units/kg/day [P < 0.001 and P = 0.002]). Peak ß-hydroxybutyrate levels during IWT were lower with combination therapy than with SGLT2 inhibitor (2.0 vs. 2.4 mmol/L; P = 0.048) and similar to levels reached during the Baseline testing period (2.1 mmol/L). Participants reported enhanced treatment acceptability and satisfaction with combination therapy. CONCLUSIONS: Glucagon antagonism enhances the therapeutic effects of SGLT2 inhibition in type 1 diabetes. Combination therapy improves glycemic control, reduces insulin dosing, and suggests a strategy to unlock the benefits of SGLT2 inhibitors while mitigating the risk of diabetic ketoacidosis.

RESUMO

OBJECTIVE: Little is known about effective strategies to improve advance care planning (ACP) for persons with cognitive impairment in primary care, the most common setting of care. We describe a randomized controlled trial to test the efficacy of a multicomponent communication intervention, "Sharing Healthcare Wishes in Primary Care" (SHARE). PARTICIPANTS: Planned enrollment of 248 dyads of adults 80 years and older with possible cognitive impairment and their care partner, from primary care clinics at 2 Mid-Atlantic health systems. METHODS: The treatment protocol encompasses an introductory letter from the clinic; access to a designated facilitator trained in ACP; person-family agenda-setting to align perspectives about the family's role; and print education. The control protocol encompasses minimally enhanced usual care, which includes print education and a blank advance directive. Randomization occurs at the individual dyad-level. Patient and care partner surveys are fielded at baseline, 6-, 12-, and 24- months. Fidelity of interventionist delivery of the protocol is measured through audio-recordings of ACP conversations and post-meeting reports, and by ongoing monitoring and support of interventionists. OUTCOMES: The primary outcome is quality of end-of-life care communication at 6 months; secondary outcomes include ACP process measures. An exploratory aim examines end-of-life care quality and bereaved care partner experiences for patients who die by 24 months. CONCLUSIONS: Caregiver burden, clinician barriers, and impaired decisional capacity amplify the difficulty and importance of ACP discussions in the context of cognitive impairment: this intervention will comprehensively examine communication processes for this special subpopulation in a key setting of primary care. REGISTRATION: ClinicalTrials.gov: NCT04593472.

RESUMO

AIM: To determine the effects of astaxanthin treatment on lipids, cardiovascular disease (CVD) markers, glucose tolerance, insulin action and inflammation in individuals with prediabetes and dyslipidaemia. MATERIALS AND METHODS: Adult participants with dyslipidaemia and prediabetes (n = 34) underwent baseline blood draw, an oral glucose tolerance test and a one-step hyperinsulinaemic-euglycaemic clamp. They were then randomized (n = 22 treated, 12 placebo) to receive astaxanthin 12 mg daily or placebo for 24 weeks. Baseline studies were repeated after 12 and 24 weeks of therapy. RESULTS: After 24 weeks, astaxanthin treatment significantly decreased low-density lipoprotein (-0.33 ± 0.11 mM) and total cholesterol (-0.30 ± 0.14 mM) (both P < .05). Astaxanthin also reduced levels of the CVD risk markers fibrinogen (-473 ± 210 ng/mL), L-selectin (-0.08 ± 0.03 ng/mL) and fetuin-A (-10.3 ± 3.6 ng/mL) (all P < .05). While the effects of astaxanthin treatment did not reach statistical significance, there were trends toward improvements in the primary outcome measure, insulin-stimulated, whole-body glucose disposal (+0.52 ± 0.37 mg/m2 /min, P = .078), as well as fasting [insulin] (-5.6 ± 8.4 pM, P = .097) and HOMA2-IR (-0.31 ± 0.16, P = .060), suggesting improved insulin action. No consistent significant differences from baseline were observed for any of these outcomes in the placebo group. Astaxanthin was safe and well tolerated with no clinically significant adverse events. CONCLUSIONS: Although the primary endpoint did not meet the prespecified significance level, these data suggest that astaxanthin is a safe over-the-counter supplement that improves lipid profiles and markers of CVD risk in individuals with prediabetes and dyslipidaemia.

RESUMO

AIMS: To determine the effect of TTP399, a hepatoselective glucokinase activator, on the risk of ketoacidosis during insulin withdrawal in individuals with type 1 diabetes (T1D). MATERIALS AND METHODS: Twenty-three participants with T1D using insulin pump therapy were randomized to 800 mg TTP399 (n = 12) or placebo (n = 11) for 7 to 10 days. After the treatment period, an insulin withdrawal test (IWT) was performed, during which insulin pumps were removed to induce ketogenesis. The IWT was stopped after 10 hours or if blood glucose reached >399 mg/dL [22.1 mmol/L], if beta-hydroxybutyrate (BHB) was >3.0 mmol/L, or for patient discomfort. The primary endpoint was the proportion of participants who reached BHB concentrations of 1 mmol/L or greater. RESULTS: During the 7- to 10-day treatment period, mean fasting plasma glucose was significantly reduced ( -27.6 vs. -4.4 mg/dL [-1.5 vs. -0.2 mmol/L]; P = 0.03) and there were fewer adverse events, including hypoglycaemia, in the TTP399-treated arm. During the IWT, no differences were observed between TTP399 and placebo in mean serum BHB concentration, mean duration of IWT, or BHB at termination of IWT. However, serum bicarbonate was numerically higher and urine acetoacetate was quantitatively lower in the TTP399-treated participants. As a result of higher bicarbonate values, none of the TTP399-treated participants met the prespecified criteria for diabetic ketoacidosis (DKA), defined as BHB >3 mmol/L and serum bicarbonate <18 mEq/L, compared to 42% of placebo-treated participants. CONCLUSIONS: When used as an adjunctive therapy to insulin, TTP399 improves glycaemia without increasing hypoglycaemia in individuals with T1D. During acute insulin withdrawal, TTP399 did not increase BHB concentrations and decreased the incidence of DKA.

RESUMO

BACKGROUND: Assess the feasibility of using goal attainment scaling (GAS) in care planning for older adults with complex needs. GAS is an individualized approach to goal setting and follow up using a quantified scale. To date, little is known about the feasibility of GAS among this population. METHODS: We conducted a qualitative study with a sample of 28 older adults and 23 providers from diverse settings to evaluate the value and challenges of this approach. We conducted semi-structured interviews and iteratively coded and analyzed interview transcripts for themes related to value, challenges, and implementation. RESULTS: Most older adults and providers reported that the GAS approach added value to the care encounter. GAS supported collaboration and patient accountability for their goals, though it could be demotivating to some patients. Some older adults and providers noted that GAS could be confusing and that it was uncomfortable to talk about negative outcomes (i.e., the - 2 and - 1 boxes of the scale). Factors that facilitated implementation included using visual copies of the GAS forms, having an established patient-provider relationship, practicing the approach, and having previous goal-related clinical training. CONCLUSIONS: GAS was feasible to implement across diverse settings, and, despite challenges, both older adults and providers reported that it added value to care planning encounters with the potential to improve delivery of person-centered care. Further efforts to demonstrate the applicability and benefit of this method for older adults are warranted, particularly to address implementation of the approach.

RESUMO

Individuals with type 1 diabetes have an impaired glucagon counterregulatory response to hypoglycemia. Sodium-glucose cotransporter (SGLT) inhibitors increase glucagon concentrations. We evaluated whether SGLT inhibition restores the glucagon counterregulatory hormone response to hypoglycemia. Adults with type 1 diabetes (n = 22) were treated with the SGLT2 inhibitor dapagliflozin (5 mg daily) or placebo for 4 weeks in a randomized, double-blind, crossover study. After each treatment phase, participants underwent a hyperinsulinemic-hypoglycemic clamp. Basal glucagon concentrations were 32% higher following dapagliflozin versus placebo, with a median within-participant difference of 2.75 pg/mL (95% CI 1.38-12.6). However, increased basal glucagon levels did not correlate with decreased rates of hypoglycemia and thus do not appear to be protective in avoiding hypoglycemia. During hypoglycemic clamp, SGLT2 inhibition did not change counterregulatory hormone concentrations, time to recovery from hypoglycemia, hypoglycemia symptoms, or cognitive function. Thus, despite raising basal glucagon concentrations, SGLT inhibitor treatment did not restore the impaired glucagon response to hypoglycemia. We propose that clinical reduction in hypoglycemia associated with these agents is a result of changes in diabetes care (e.g., lower insulin doses or improved glycemic variability) as opposed to a direct, physiologic effect of these medications on α-cell function.

RESUMO

Purpose: The purpose of the study is to capture goals expressed by older adults with functional limitations and their caregivers. Methods: Through focus groups and interviews, 76 older adults with ≥1 activity of daily living limitation and 28 family/friend caregivers were asked about what mattered most to them and their goals for care. Transcripts were coded using an existing taxonomy. Goals that did not fit the taxonomy were assigned new codes. Results: We identified more than 50 goals in eight domains. Domains included (a) Medical Care; (b) Quality of Life: Physical; (c) Quality of Life: Social and Emotional; (d) Access to Services and Supports; (e) Caregiver Needs and Concerns; (f) End of Life; (g) Independence; and (h) Acceptable Housing. Conclusion: While there is overlap between identified goals and the existing taxonomy, new goals emerged. The goal domains identified could serve as a framework to improve and measure the quality of goal-oriented care for older adults with complex needs.

RESUMO

OBJECTIVE: To quantify and contextualize the risk for coronavirus disease 2019 (COVID-19)-related hospitalization and illness severity in type 1 diabetes. RESEARCH DESIGN AND METHODS: We conducted a prospective cohort study to identify case subjects with COVID-19 across a regional health care network of 137 service locations. Using an electronic health record query, chart review, and patient contact, we identified clinical factors influencing illness severity. RESULTS: We identified COVID-19 in 6,138, 40, and 273 patients without diabetes and with type 1 and type 2 diabetes, respectively. Compared with not having diabetes, people with type 1 diabetes had adjusted odds ratios of 3.90 (95% CI 1.75-8.69) for hospitalization and 3.35 (95% CI 1.53-7.33) for greater illness severity, which was similar to risk in type 2 diabetes. Among patients with type 1 diabetes, glycosylated hemoglobin (HbA1c), hypertension, race, recent diabetic ketoacidosis, health insurance status, and less diabetes technology use were significantly associated with illness severity. CONCLUSIONS: Diabetes status, both type 1 and type 2, independently increases the adverse impacts of COVID-19. Potentially modifiable factors (e.g., HbA1c) had significant but modest impact compared with comparatively static factors (e.g., race and insurance) in type 1 diabetes, indicating an urgent and continued need to mitigate severe acute respiratory syndrome coronavirus 2 infection risk in this community.

RESUMO

BACKGROUND: Older adults with complex care needs face trade-offs in determining the right course of treatment. The Centers for Medicare and Medicaid Services identified 'Care is personalized and aligned with patient's goals' as a key meaningful measures category, yet existing quality measures typically assess disease-specific care and may not effectively evaluate what is most important to older adults and family members. Measures based on individualised goals and goal-based outcomes have been proposed as an alternative but are not routinely assessed or implemented. OBJECTIVES: We tested two approaches to assessing goal-based outcomes that allow individuals to set goals based on their own priorities and measure progress-(1) goal attainment scaling and (2) existing, validated patient-reported outcome measures (PROM). METHODS: A prospective cohort study of feasibility in seven sites (33 clinicians) of the two approaches with 229 individuals. We calculated performance on a measure of achievement of individually identified goals. RESULTS: Both approaches were successfully implemented in a non-randomly selected population, and a goal-based outcome could be calculated for 189 (82%) of participants. Most individuals met their goal-based outcome (73%) with no statistical difference between the goal attainment scaling approach (74%) and the patient-reported outcomes approach (70%). Goals were heterogeneous ranging from participating in activities, health management, independence and physical health. Clinicians chose to use goal attainment scaling (n=184, 80%) more often than PROMs (n=49, 20%) and rated the goal attainment scaling approach as useful for providing patient care. CONCLUSION: Goal-based outcomes have the potential to both improve the way healthcare is provided and fill a critical gap in value-based payment.

RESUMO

BACKGROUND: Improving quality of care for people with multiple chronic conditions (MCCs) requires performance measures reflecting the heterogeneity and scope of their care. Since most existing measures are disease specific, performance measures must be refined and new measures must be developed to address the complexity of care for those with MCCs. OBJECTIVES: To describe development of the Performance Measurement for People with Multiple Chronic Conditions (PM-MCC) conceptual model. STUDY DESIGN: Framework development and a national stakeholder panel. METHODS: We used reviews of existing conceptual frameworks of performance measurement, review of the literature on MCCs, input from experts in the multistakeholder Steering Committee, and public comment. RESULTS: The resulting model centers on the patient and family goals and preferences for care in the context of multiple care sites and providers, the type of care they are receiving, and the national priority domains for healthcare quality measurement. CONCLUSIONS: This model organizes measures into a comprehensive framework and identifies areas where measures are lacking. In this context, performance measures can be prioritized and implemented at different levels, in the context of patients' overall healthcare needs.

RESUMO

The primary study objective is to assess how three major health reform care coordination initiatives (Accountable Care Organizations, Independence at Home, and Community-Based Care Transitions) measure concepts critical to care coordination for people with multiple chronic conditions. We find that there are major differences in quality measurement across these three large and politically important programs. Quality measures currently used or proposed for these new health reform-related programs addressing care coordination primarily capture continuity of care. Other key areas of care coordination, such as care transitions, patient-centeredness, and cross-cutting care across multiple conditions are infrequently addressed. The lack of a comprehensive and consistent measure set for care coordination will pose challenges for healthcare providers and policy makers who seek, respectively, to provide and reward well-coordinated care. In addition, this heterogeneity in measuring care coordination quality will generate new information, but will inhibit comparisons between these care coordination programs.

RESUMO

OBJECTIVE: Family caregivers often accompany patients to medical visits; however, it is unclear whether caregivers rate the quality of patients' care similarly to patients. This study aimed to (1) quantify the level of agreement between patients' and caregivers' reports on the quality of patients' care and (2) determine how the level of agreement varies by caregiver and patient characteristics. DESIGN: Cross-sectional analysis. PARTICIPANTS: Multimorbid older (aged 65 and above) adults and their family caregivers (n = 247). METHODS: Quality of care was rated separately by patients and their caregivers using the Patient Assessment of Chronic Illness Care (PACIC) instrument. The level of agreement was examined using a weighted kappa statistic (Kw). RESULTS: Agreement of caregivers' and patients' PACIC scores was low (Kw = 0.15). Patients taking ten or more medications per day showed less agreement with their caregivers about the quality of care than patients taking five or fewer medications (Kw = 0.03 and 0.34, respectively, P < 0.05). Caregivers who reported greater difficulty assisting patients with health care tasks had less agreement with patients about the quality of care being provided when compared with caregivers who reported no difficulty (Kw = -0.05 and 0.31, respectively, P < .05). Patient-caregiver dyads had greater agreement on objective questions than on subjective questions (Kw = 0.25 and 0.15, respectively, P > 0.05). CONCLUSION: Patient-caregiver dyads following a more complex treatment plan (i.e. taking many medications) or having more difficulty following a treatment plan (i.e. having difficulty with health care tasks) had less agreement. Future qualitative research is needed to elucidate the underlying reasons patients and caregivers rate the quality of care differently.

RESUMO

BACKGROUND: Self-care management is recognized as a key component of care for multimorbid older adults; however, the characteristics of those most likely to participate in Chronic Disease Self-Management (CDSM) programs and strategies to maximize participation in such programs are unknown. OBJECTIVES: To identify individual factors associated with attending CDSM programs in a sample of multimorbid older adults. RESEARCH DESIGN: Participants in the intervention arm of a matched-pair cluster-randomized controlled trial of the Guided Care model were invited to attend a 6-session CDSM course. Logistic regression was used to identify factors independently associated with attendance. SUBJECTS: All subjects (N = 241) were aged 65 years or older, were at high risk for health care utilization, and were not homebound. MEASURES: Baseline information on demographics, health status, health activities, and quality of care was available for CDSM participants and nonparticipants. Participation was defined as attendance at 5 or more CDSM sessions. RESULTS: A total of 22.8% of multimorbid older adults who were invited to CDSM courses participated in 5 or more sessions. Having better physical health (odds ratio [95% confidence interval] = 2.3 [1.1-4.8]) and rating one's physician poorly on support for patient activation (odds ratio [95% confidence interval] = 2.8 [1.3-6.0]) were independently associated with attendance. CONCLUSIONS: Multimorbid older adults who are in better physical health and who are dissatisfied with their physicians' support for patient activation are more likely to participate in CDSM courses.

RESUMO

DYNHA SF-36 is a computerized adaptive test version of the SF-36 Health Survey. The feasibility of administering a modified DYNHA SF-36 to adults with HIV was evaluated with Johns Hopkins University Moore (HIV) Clinic patients (N=100) and Internet consumer health panel members (N=101). Participants completed the DYNHA SF-36, modified to capture seven health domains [(physical function (PF), role function (RF, without physical or emotional attribution), bodily pain (BP), general health, vitality (VT), social function (SF), mental health (MH)], and scored to produce two summary components [Physical Component Summary (PCS), Mental Component Summary (MCS)]. Item-response theory-based response consistency, precision, mean scores, and discriminant validity were examined. A higher percentage of Internet participants responded consistently to the DYNHA SF-36. For each domain, three standard deviations were covered with five items (90% reliability); however, RF and SF scores were less precise at the upper end of measurement (better functioning). Mean scores were slightly higher for the Internet sample, with the exception of VT and MCS. Clinic and Internet participants reporting an AIDS diagnosis had significantly lower mean PCS and PF scores than those without a diagnosis. Additionally, significantly lower RF and BP scores were found for Internet participants reporting an AIDS diagnosis. The measure was well accepted by the majority of participants, although Internet respondents provided lower ratings for the tool's usefulness. The DYNHA SF-36 has promise for measuring the impact of HIV and its treatment in both the clinic setting and through telemonitoring.

RESUMO

BACKGROUND: Family caregivers provide assistance with health care tasks for many older adults with chronic illnesses. The difficulty they experience in providing this assistance, and related implications for their well-being, have not been well described. OBJECTIVE: The objectives of this study are: (1) to describe caregiver's health care task difficulty (HCTD), (2) determine the characteristics associated with HCTD, and (3) explore the association between HCTD and caregiver well-being. DESIGN: This is a cross-sectional study. PARTICIPANTS: Baseline sample of caregivers to older (aged 65+ years) multimorbid adults enrolled in an ongoing cluster-randomized controlled trial (N = 308). MAIN MEASURES: The HCTD scale (0-16) is comprised of questions measuring self-reported difficulty in assisting older adults with eight health care tasks, including taking medication, visiting health care providers, and managing medical bills. Caregivers were categorized using this scale into no, low, medium, and high HCTD groups. We used ordinal logistic regression and multivariate linear regression analyses to examine the relationships between HCTD, caregiver self-efficacy, caregiver strain (Caregiver Strain Index), and depression (Center for Epidemiological Studies Depression Scale), controlling for patient and caregiver socio-demographic and health factors. KEY RESULTS: Caregiver age and number of health care tasks performed were positively associated with increased HCTD. The quality of the caregiver's relationship with the patient, and self-efficacy were inversely associated with increased HCTD. A one-point increase in self-efficacy was associated with a significant lower odds of reporting high HCTD (OR, 0.64; 95% CI, 0.54, 0.77).Adjusted linear regression models indicated that high HCTD was independently associated with significantly greater caregiver strain (B, 2.7; 95% CI, 1.12, 4.29) and depression (B, 3.01; 95% CI, 1.06, 4.96). CONCLUSIONS: This study demonstrates that greater HCTD is associated with increased strain and depression among caregivers of multimorbid older adults. That caregiver self-efficacy was strongly associated with HCTD suggests health-system-based educational and empowering interventions might improve caregiver well-being.

RESUMO

CONTEXT: Public policy regarding family caregiving for disabled older adults is affected by their estimated number, their attributes, and the services provided. The available national surveys, however, do not have a uniform approach to ascertaining the number of family caregivers, so their estimated number varies widely. METHODS: This article looks at nationally representative, population-based surveys of family caregivers conducted between 1985 and 2010 to find methods pertinent to ascertaining the number of caregivers. The surveys' design, definition of disability, and approach to identifying and defining caregivers of disabled adults aged sixty-five and older were identified, and cross-survey estimates were compared. FINDINGS: Published estimates of the numbers of caregivers of older disabled adults ranged from 2.7 million to 36.1 million in eight national surveys conducted between 1992 and 2009. The surveys were evenly divided between caregivers identified by disabled older adults (n= 4, "disability surveys") and self-identified (n= 4, "caregiver self-identification surveys"). The estimated number of family caregivers of disabled adults aged sixty-five and older was, on average, 4.8 million in disability surveys and 24.4 million in caregiver self-identification surveys. CONCLUSIONS: The number of family caregivers of disabled older adults estimated by national surveys varied substantially. Greater consistency in defining caregivers could yield more informative estimates and also advance policy efforts to more effectively monitor and support family caregivers.

PURPOSE: Guided Care (GC) is a model of health care for multimorbid older adults that is provided by a registered nurse who works with the patients' primary care physician (PCP). The purpose of this study was to determine whether GC improves patients' primary caregivers' depressive symptoms, strain, productivity, and perceptions of the quality of care recipients' chronic illness care. DESIGN AND METHODS: A cluster-randomized controlled trial of GC was conducted within 14 PCP teams. The study sample included 196 primary caregivers who completed baseline and 18-month surveys and whose care recipients remained alive and enrolled in the GC study for 18 months. Caregiver outcomes included the following: depressive symptoms (Center for Epidemiological Studies-Depression scale), strain (Modified Caregiver Strain Index), the quality of care recipients' chronic illness care [Patient Assessment of Chronic Illness Care (PACIC)], and personal productivity (Work Productivity and Activity Impairment questionnaire, adapted for caregiving). RESULTS: In multivariate regression models, between-group differences in depression, strain, work productivity, and regular activity productivity were not statistically significant after 18 months, but GC caregivers reported the overall quality of their recipients' chronic illness care to be significantly higher (adjusted beta = 0.40, 95% confidence interval : 0.14-0.67). Quality was significantly higher in 4 of 5 PACIC subscales, reflecting the dimensions of goal setting, coordination of care, decision support, and patient activation. IMPLICATIONS: GC improved the quality of chronic illness care received by multimorbid care recipients but did not improve caregivers' depressive symptoms, affect, or productivity.
