Blended collaborative care in the secondary prevention of coronary heart disease improves risk factor control: Results of a randomised feasibility study.

BACKGROUND: Risk factor control is essential in limiting the progression of coronary heart disease, but the necessary active patient involvement is often difficult to realise, especially in patients suffering psychosocial risk factors (e.g. distress). Blended collaborative care has been shown as an effective treatment addition, in which a (non-physician) care manager supports patients in implementing and sustaining lifestyle changes, follows-up on patients, and integrates care across providers, targeting both, somatic and psychosocial risk factors. AIMS: The aim of this study was to test the feasibility, acceptance and effect of a six-month blended collaborative care intervention in Germany. METHODS: For our randomised controlled pilot study with a crossover design we recruited coronary heart disease patients with ⩾1 insufficiently controlled cardiac risk factors and randomised them to either immediate blended collaborative care intervention (immediate intervention group, n=20) or waiting control (waiting control group, n=20). RESULTS: Participation rate in the intervention phase was 67% (n=40), and participants reported high satisfaction (M=1.63, standard deviation=0.69; scale 1 (very high) to 5 (very low)). The number of risk factors decreased significantly from baseline to six months in the immediate intervention group (t(60)=3.07, p=0.003), but not in the waiting control group t(60)=-0.29, p=0.77). Similarly, at the end of their intervention following the six-month waiting period, the waiting control group also showed a significant reduction of risk factors (t(60)=3.88, p<0.001). CONCLUSION: This study shows that blended collaborative care can be a feasible, accepted and effective addition to standard medical care in the secondary prevention of coronary heart disease in the German healthcare system.

Motivational interviewing can support physical activity in elderly patients with diastolic heart failure: results from a pilot study.

AIMS: Patients suffering from heart failure with preserved ejection fraction (HFpEF) report similar symptoms and reduction in quality of life to those with reduced ejection fraction but remain largely untreated. We conducted a preliminary evaluation of the acceptance, feasibility, and efficacy of a motivational interviewing (MI) intervention to support elderly patients suffering from HFpEF in maintaining or starting physical activity. METHODS AND RESULTS: At the conclusion of the exercise training in diastolic heart failure parent trial that examined the effects of supervised exercise, patients with HFpEF were offered participation in a two-group pilot study. Based on their preference, consenting patients were assigned to either a 6 month MI intervention group (n = 19) or their physicians' usual care (n = 20). To support participants in increasing and/or maintaining their physical activity, counsellors delivered a mean of 6.5 MI sessions (face to face and via telephone) and also provided a physical activity diary as self-management tool. At baseline and 6 months, we assessed participants' physical activity motivation (Sportbezogene Selbstkonkordanz Scale) and their physical improvements with the 6 min walk test and a cardiopulmonary exercise test. Of the entire sample (N = 39), 46% were female, their mean age was 73, 90% were in New York Heart Association Class II, and the mean ejection fraction was 61.4%. The majority of MI participants rated the intervention as acceptable, 90% perceived MI as helpful in setting specific exercise goals and overcoming barriers concerning physical activity, and 58% considered the physical activity diary as very helpful. Three-quarters of MI participants (79%) reported an increase in their physical activity compared with the previous year. Intervention participants showed a greater increase in median peak VO2 from baseline to 6 months (baseline: 18.4 mL/kg/min; 6 months: 20.4 mL/kg/min) compared with the control group (baseline: 20.0 mL/kg/min; 6 months: 19.2 mL/kg/min; P = 0.015). There was no significant change in motivation on the Sportbezogene Selbstkonkordanz Scale for either group (MI: 1.7 vs. 3, P = 0.55; control: 4.7 vs. 4, P = 0.26) nor did patients show any significant improvements in the 6 min walk test (MI: 549 vs. 540 m, P = 0.80; control: 572 vs. 580 m, P = 0.37). Counsellors rated the implementation of the MI intervention as feasible. CONCLUSIONS: The results from this pilot study suggest that our MI intervention was well accepted by participants and deemed feasible. It also appears to be an effective treatment to increase and maintain physical activity and exercise capacity in patients suffering from HFpEF. Our findings need to be confirmed in a randomized clinical trial with larger and unselected patient cohorts.
