Tailored Support for Type 2 Diabetes Patients With an Acute Coronary Event After Discharge From Hospital (Diacourse)

Background: In type 2 diabetes mellitus patients, an acute coronary event (ACE) may result in a decreased quality of life and increased distress. According to the American Diabetes Association, transition from the acute care setting is a high-risk time for all patients, but tailored support specific to diabetes is scarce in that period. The investigators developed an intervention by a diabetes nurse to help diabetic patients reduce distress after their first ACE. The intervention is based on Bandura's Social Cognitive Theory, Leventhal's Common Sense Model, and on results of focus groups which were conducted to define the needs and wishes of type 2 diabetes patients and their partners regarding professional support after an ACE. The aim of this study is to evaluate the effectiveness of the intervention to reduce distress. The hypothesis is that patients who receive the intervention will have less diabetes related distress compared to the control group.

Methods/Design: Randomized controlled trial. Patients will be recruited directly after discharge from hospital. A diabetes nurse will visit the patients in the intervention group (n = 100) within three weeks after discharge from hospital, two weeks later and two months later. The control group (n = 100) will receive a telephone consultation. The primary outcome is diabetes related distress, measured with the Problem Areas in Diabetes questionnaire (PAID). Secondary outcomes are quality of life, anxiety, depression, HbA1c, blood pressure and lipids. Mediating variables are self-management, self-efficacy and illness representations. Variables will be measured with questionnaires directly after discharge from hospital and five months later. Biomedical variables will be obtained from the records from the primary care physician and the hospital. Differences between groups in change over time will be analyzed according to the intention-to-treat principle.

Discussion: Type 2 diabetes patients who experience a first ACE need tailored support after discharge from the hospital. This trial will provide evidence of the effectiveness of a supportive intervention to reduce distress in these patients.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Home visits; In addition to usual care the patients will receive three home visits from a trained diabetes nurse. The first visit (65 minutes) is within three weeks after discharge from the hospital; the second visit (45 minutes) is two weeks later and the third visit (45 minutes) is two months after the second home visit.	Other: Home visits; In addition to usual care the patients will receive three home visits from a trained diabetes nurse. The first visit (65 minutes) is within three weeks after discharge from the hospital; the second visit (45 minutes) is two weeks later and the third visit (45 minutes) is two months after the second home visit.
Other: Consultation by telephone; In addition to usual care patients will receive a consultation by telephone within three weeks after discharge to offer them personal attention. In this consultation they will get the opportunity to discuss in ten to fifteen minutes how they feel in the period after discharge.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Diabetes related distress	Diabetes related distress measure with the Problem Areas in Diabetes (PAID) questionnaire. The PAID is a Self-reported questionnaire consisting of twenty statements identified as common negative emotions related to living with diabetes. Each item is rated on a 5-point Likert scale, ranging from 0 ("not a problem") to 4 ("a serious problem"). The total score is transformed to a 0-100 scale, with higher score representing higher distress.	At 2 weeks and 5 months after discharge from hospital

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Well-being	Measured with the WHO-Five Well-being Index (WHO-5). The five items covering positive mood (good spirits, relaxation), vitality (being active and waking up fresh and rested), and general interests (being interested in things) in the past two weeks	At 2 weeks and 5 months after discharge from hospital
Change in Quality of life	Euroqol 5 Dimensions (EQ-5D) and the Euroqol Visual Scale (EQ-VAS). The EQ-5D measures general health status on five dimensions: Mobility; Self-care; Usual activities; Pain/discomfort; Anxiety/depression The EQ-VAS measures the overall health state on a graded, vertical line.	At 2 weeks and 5 months after discharge from hospital
Change in Anxiety and depression	Measured with the Hospital Anxiety and Depression Scale (HADS). A questionnaire measuring anxiety (7 items) and depression (7 items).	At 2 weeks and 5 months after discharge from hospital
Change in Physical activity	Measured with the International Physical Activity Questionnaire (IPAQ). 29 Items measure how many days' physical activities are performed during the past seven days in four domains (work, transportation, housework and leisure-time).	At 2 weeks and 5 months after discharge from hospital
Change in Self care	Measured with the Summary of the Diabetes Self-Care Activities Measure (SDSCA). Eleven items assessing several aspects of the diabetes regimen: general diet, specific diet, exercise, blood glucose testing, foot care, and smoking. Items measure how many days a patient has performed self-care activities in the last seven days.	At 2 weeks and 5 months after discharge from hospital
Change in Diabetes coping	Measured with the Diabetes Coping Measure (DCM) consisting of four scales measuring diabetes coping: tackling spirit, avoidance, passive resignation and diabetes integration.	At 2 weeks and 5 months after discharge from hospital
Change in Biomedical variables	Blood pressure, blood lipids (total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides) and body mass index	At 2 weeks and 5 months after discharge from hospital

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Self-efficacy	Measured with the Confidence in Diabetes Self-care questionnaire consisting of 20 items measuring diabetes specific self-efficacy.	At 2 weeks and 5 months after discharge from hospital
Change in Illness perceptions	Measured with the Illness Perception Questionnaire (IPQ) - short version. Questionnaire assessing the cognitive representation of illness, focuses on seven scales, assessing (1) Timeline acute/chronic and (2) Timeline cyclical (3) Consequences (4) Personal control (5) Treatment control (6) Illness coherence (7) Emotional representation	At 2 weeks and 5 months after discharge from hospital
Change in Spousal support	Measured with the Active Engagement, Protective Buffering and Overprotection (ABO) questionnaire. Five items measure active engagement, eight items measure protective buffering and six items measure overprotection	At 2 weeks and 5 months after discharge from hospital
