Setbacks in diet adherence and emotional distress: a study of older patients with type 2 diabetes and their spouses.

OBJECTIVES: We investigated patients' difficulties in managing their diet (i.e. diet setbacks) and associations with change in disease-specific and general emotional distress (diabetes distress and depressive symptoms) among patients with type 2 diabetes and their spouses. METHOD: Data for this study were collected in couples' homes (N=115 couples) using structured interviews and self-administered questionnaires at three time points: baseline (T1), six months after baseline (T2) and 12 months after baseline (T3). RESULTS: Patients' diet setbacks were associated with an increase in their diabetes distress in the shorter-term (over six months). Patients' diet setbacks were not associated with longer-term change in diabetes distress or with change in depressive symptoms at either time point (six months or one year). In contrast, spouses' perceptions of patients' diet setbacks were associated with increases in their own diabetes distress at both time points (over six months and one year), and also with an increase in their depressive symptoms in the longer-term (over one year). CONCLUSION: Findings reveal detrimental consequences of patients' diet nonadherence for emotional well-being that extend to the well-being of their spouses.

An innovative role for nurse practitioners in managing chronic disease.

Under the current care delivery model, persons with chronic illnesses, such as diabetes, are not receiving all recommended interventions and failing to meet targeted outcomes. The Chronic Care Model provides a framework for new approaches and roles for many members of the multidisciplinary team. Using the Chronic Care Model as a guide, a group of hospital-based clinics in an academic system incorporated nurse practitioners into the care model for patients with diabetes. Through use of planned visits, a patient registry, drug intensification protocols, and collaboration with other members of the team, the pilot sample improved processes of care and clinical outcomes. Use of nurse practitioners in this model of care for chronically ill patient populations has economic implications, as the payers begin to pay for performance.

Older adults' beliefs about the timeline of type 2 diabetes and adherence to dietary regimens.

The common-sense model posits that behavioural coping with illness is shaped by a complex combination of individuals' abstract and concrete beliefs about their illness. We investigated this theoretical assumption in a study of 116 older adults diagnosed with type 2 diabetes who completed in-person interviews at baseline and six and 12 months later. Specifically, we examined (1) the interaction of patients' abstract and concrete beliefs about the timeline of their diabetes as a predictor of change in adherence to a healthy diet and (2) whether these interactive effects differ among male and female patients. Abstract timeline beliefs were conceptualised as those pertaining to disease duration; concrete timeline beliefs were conceptualised as those pertaining to variability of disease symptoms (i.e. symptoms are stable versus fluctuating). As predicted, duration beliefs were positively associated with improvement in adherence among patients who viewed disease symptoms as stable, but not among those who viewed symptoms as variable. When gender was considered, these interactive effects were observed among male (but not female) patients. Findings revealed that the behavioural effects of men's abstract knowledge about their diabetes were conditioned by their concrete representations of the disease, suggesting a bottom-up process of influence with implications for intervention.

Spouses' attempts to regulate day-to-day dietary adherence among patients with type 2 diabetes.

OBJECTIVE: To investigate daily dietary adherence and diabetes-specific distress among older adults with type 2 diabetes mellitus (T2DM) as a function of spouses' diet-related support and diet-related control (persuasion and pressure) and whether these daily processes differ among couples who do and do not appraise responsibility for managing T2DM as shared. METHODS: End-of-day diaries were completed by 126 couples in which one partner had T2DM (patient) and the other did not (spouse). Using electronic diary methods, each partner independently recorded data for 24 consecutive days (patients recorded their day's dietary adherence and diabetes-specific distress; spouses recorded their day's involvement in patients' dietary management). To assess dietary adherence, patients reported the extent to which they followed dietary recommendations that day with items from the Summary of Diabetes Self-Care Activities Measure. To assess diabetes-specific distress, patients reported the extent to which they worried about diabetes that day using items from the Problem Areas in Diabetes (PAID) scale. RESULTS: Multilevel modeling revealed that, relative to the prior day, spouses' diet-related support was associated with increases in patients' adherence whereas diet-related persuasion and pressure were associated with decreases in adherence; spouses' pressure was associated with increases in patients' diabetes-specific distress. When partners appraised responsibility for managing T2DM as shared, support was associated with decreases in diabetes-specific distress; pressure was associated with decreases in adherence. CONCLUSIONS: Our findings offer insight into partners' day-to-day disease-related interactions and identify those that are likely to be beneficial versus detrimental for patients' physical and psychological health.

Influences of spousal support and control on diabetes management through physical activity.

OBJECTIVES: Spouses may be involved in their partner's diabetes management by providing social support to affirm healthy behaviors and social control to modify health behaviors. Yet, investigations of the influence of spousal involvement on daily patient health behaviors are limited. In daily diaries, we investigated how spousal support and control independently and jointly influence patient physical activity and efficacy to engage in physical exercise on a daily basis. METHODS: Older adults (age 55 and older) with Type 2 diabetes and their spouses (N = 70 couples) completed electronic diaries for seven consecutive days that assessed spouse-reported involvement and patient-reported minutes of physical exercise and efficacy to engage in future physical exercise. A subset of patients (N = 53) also wore an activity monitoring device on the wrist that provided a measure of energy expenditure. RESULTS: Multilevel analyses indicated that on a daily basis, spousal support was positively associated with physical activity, whereas spousal control was either unrelated or linked to less physical activity. On days in which spouses provided high levels of both support and control, however, patients felt more efficacious that day about exercising tomorrow and exhibited an increase in energy expenditure on the next day. CONCLUSIONS: Findings suggest that spousal exercise support on its own or in conjunction with spousal exercise control may facilitate daily diabetes management through physical activity.

Improving care in a resident practice for patients with diabetes.

BACKGROUND: Curricular redesign and introduction of the Chronic Care Model in our residency clinic during 2005-2007 achieved limited success in glycemic (glycated hemoglobin level [A(1c)]), lipid (low-density lipoprotein fraction [LDL]), and blood pressure (BP) control for patients with diabetes. INTERVENTION: Beginning in January 2008, ancillary staff performed previsit, protocol-driven reviews of medical records of patients with diabetes to identify those not at A(1c), LDL, and BP goals; inserted electronic prompts into the records regarding deficiencies; and obtained samples for A(1c) or lipid panel when needed. Faculty feedback regarding resident-specific panel reviews was added in May 2008, and point-of-care A(1c) testing was implemented in February 2009. METHODS: We conducted a 2-year retrospective study of all patients at our facility with diabetes mellitus, who had at least 1 visit during January to June 2008 (baseline) and 1 visit during July to December 2009 (follow-up). Measures included the most current A(1c), LDL, and BP results. Paired outcome results were compared using the McNemar χ(2) test. RESULTS: A total of 522 patients with diabetes mellitus were seen during the baseline and follow-up periods, and 456 patients (87.4%) had paired A(1c) results, with A(1c) < 7.0% for 138 of 456 patients (30.3%) at baseline and 166 of 456 patients (36.4%) at follow-up (P  =  .011). For LDL, 460 patients (88.1%) had paired results, with LDL < 100 mg/dL for 225 of 460 patients (48.9%) at baseline and 262 of 460 patients (57.0%) at follow-up (P  =  .004). A total of 513 patients (98.3%) had paired BP results in which the BP < 130/80 mm Hg for 124 of 513 patients (24.2%) at baseline and for 188 of 513 patients (36.6%) at follow-up (P < .001). There were 421 patients (80.7%) with paired results for all 3 measures, with 17 of 421 patients (4.0%) at goal at baseline and 41 of 421 patients (9.7%) at goal at follow-up (P  =  .001). CONCLUSION: The interventions resulted in statistically significant improvements in the proportion of patients with diabetes who attained goal for A(1c), LDL, and BP levels. Our redesign elements may be useful in enhancing resident education and in improving patient care.

When the going gets tough, does support get going? Determinants of spousal support provision to type 2 diabetic patients.

Although spousal support has been linked to positive outcomes in various health-related contexts, some research has found that the amount of social support provided to those who are chronically ill deteriorates over time. The current study refines the literature by considering multiple factors associated with spouses' provision of emotional support to partners with Type 2 diabetes. This diary study (N = 126 couples) examined the roles that stressor (disease severity and diabetes-specific anxiety), recipient (negative and positive affect), provider (negative and positive affect), and relationship (tension and enjoyment) factors play in spouses' provision of emotional support. Daily disease severity, patients' and spouses' daily negative affect, and spouses' daily relationship enjoyment were predictors of support provision. Wives, but not husbands, provided more support on days when patients experienced diabetes-specific anxiety. Results advance understanding of support provision in the context of a chronic stressor.
