Abstract

OBJECTIVES

To evaluate the efficacy of a psychoeducational intervention in improving palliative care knowledge and attitudes among caregivers, patients' close friends and families.

METHODS

A total of 150 adult cancer caregivers participated in an online U.S.-based randomized clinical trial (RCT) between December 2021 and March 2022. Participants self-reported their baseline knowledge of palliative care, then viewed a psychoeducational video on palliative care (intervention condition) or nutrition (control condition). Participants then completed outcome measures of palliative care knowledge (aim 1; Palliative Care Knowledge Scale, PaCKS) and attitudes (aim 2; Palliative Care Attitudes Scale-9-Caregiver, PCAS-9C). Regression analyses examined whether group assignment significantly predicted palliative care knowledge and attitudes while controlling for self-reported baseline knowledge and key demographic and clinical characteristics.

RESULTS

The PaCKS and PCAS-9C demonstrated excellent evidence of reliability, factor structure, and validity in this caregiver sample. The RCT succeeded on the primary outcome of increasing caregivers' palliative care knowledge (p < .001). Attitudes were favorable and did not differ between groups.

CONCLUSIONS

This study demonstrates that a single-session, psychoeducational video can improve understanding of palliative care among close friends and families of those with cancer.

PRACTICE IMPLICATIONS

This work suggests future pathways for helping families make informed decisions about initiating palliative care.

The nursing process provides a clinical decision-making framework for patients and families to establish and implement a personalized care plan. Since part of the nurse's duties is to teach patients, the steps of the nursing process are the most effective way to approach instruction. The nursing process and the teaching-learning process are inextricably linked.
It is critical to determine the patient's learning needs during the assessment. Determination of learning needs compounds data...

Cancer Survival Analysis 01:21

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Planning for learning involves the development of a teaching plan. Teaching plans are similar to nursing care plans—both follow the steps of the nursing process. Planning in the teaching process involves setting goals and outcomes. Here, goals identify what a patient needs to achieve to understand a healthcare topic better, whereas the outcomes are the action to be performed by the patient to achieve the goal within a timeframe. For example, if the goal is to educate the patient about...

Continuing Care 01:25

Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning,...
