Background: Advance care planning (ACP) is the process involves planning for future health care
focused on patient’s preference, proxy nomination and treatment decision. However, limited evidence
is available about ACP particularly in the context of patients with heart failure.

Objective: 1) examine the level of intention toward ACP, and 2) examine factors predicting intention
toward ACP among patients with heart failure.

Methods: Predictive correlational study of 80 patients with heart failure classes II-IV in hospitals in the
4th Public Health Region, Thailand. Instruments used for collecting data included 1) a demographic data
form; 2) the Attitude Regarding Advance Care Planning Questionnaire [A- ACPQ]; 3) the Subjective Norm
Questionnaire [SNQ]; 4) the Perceived Control toward Advance Care Planning Questionnaire [PC-ACPQ];
5) the Short Form 12 Item Health Survey [SF-12]; 6) the Intentions for Advance Care Planning Questionnaire
[I-ACPQ]; 7) the Knowledge Regarding Advance Care Planning Questionnaire [K-ACPQ]; and 8) the
Prognosis Awareness Questionnaire [PAQ]. Data were analyzed by descriptive statistics and the enter
method in multiple regression.

Results: The results showed that level of intention toward advance care planning of patients with heart
failure was at moderate ( ̅̅ = 19.09, S.D. = 5.41). Multiple regression analysis showed that attitude about
ACP, subjective norm, perceived control in terms of ACP, knowledge about ACP, prognostic awareness, and
health perception significantly explained 37.3% of the variance in intention toward ACP (R2 = .373, F(6,73)
= 7.23, p <.05). Attitude regarding ACP (= .322, p< .01), knowledge regarding ACP (= .248, p< .05), and
perceived control toward ACP (= .221, p< .05) were significant factors contributing to intention toward ACP
in these patients.

Conclusion: These findings suggest that nurses and healthcare providers should promote knowledge
about ACP, attitudes and perceived control toward ACP through educational interventions to increase
the intention of patients with heart failure to participate in ACP.
