“…All studies conducted transitional care interventions for patients with HF. Regarding research design, there were 10 RCTs [16,21,22,24,28,29,32,33,36,38], two quasi-experiments [23,40], two pre-and post-tests [17,26], six cohort studies [18,19,27,34,35,37], and five prospective studies [20,25,30,31,39]. Although it was necessary to establish controls to verify the effects of transitional care interventions, in six of the 25 studies [17][18][19][20]26,39], there was no comparative control group set up to verify the effectiveness of transitional care interventions.…”
