Advanced care planning (ACP) is central to patients' dignity and autonomy; however, in many countries it is underutilized. Studies that tested the effects of palliative care (PC) often included the rate of documented ACP as a secondary end point. We aimed to assess the contribution of PC to the rate of ACP among terminally ill patients by systematically reviewing relevant clinical trials.

PUBMED and “Cochrane trials” databases were screened for clinical trials published until October 2017 that compared the addition of PC to standard treatment and that had ACP as a primary or a secondary end point. Studies were assessed for validity by three investigators using the Cochrane Collaboration tool and the ROBINS-I tool for randomized controlled trials (RCTs) and for cohort studies, respectively.

Twenty-six trials with 37,924 patients were included. Four were RCTs, nine were cohort studies, and 12 were cross-sectional studies. Randomized trials had the lowest risk of bias. There was a positive correlation between the addition of PC and ACP in 25 studies, among them four randomized trials.

In this systematic review, PC was associated with improvement in the rate of ACP. Understanding the significant effect of PC on the completion of ACP is an additional emphasis on the importance of this treatment among terminally ill patients.

The aims of this systematic review were to examine the effects of the overall and the different types of the interventions on the do-not-resuscitate (DNR) designation and the time between DNR and death among cancer patients.

Data were searched from the databases of PubMed, CINAHL, EMbase, Medline, and Cochrane Library through 2 November 2017. Studies were eligible for inclusion if they were (1) randomized control trails, quasi-experimental study, and retrospective observational studies and (2) used outcome indicators of DNR designation rates. The Effective Public Health Practice Project tool was used to assess the overall quality of the included studies.

The 14 studies with a total of 7,180 participants were included in this review. There were 78.6% (11 of 14) studies that indicated that the interventions could improve the DNR designation rates. Three types of DNR interventions were identified in this review: palliative care unit service, palliative consultation services, and patient-physician communication program. The significant increases of the time between DNR designation and death only occurred in a patient-physician communication program.

The palliative care unit service provided a continuing care model to reduce unnecessary utilization of healthcare service. The palliative consultation service is a new care model to meet the needs of cancer patients in non-palliative care unit. The share decision-making communication program and physician's compassion attitudes facilitate to make DNR decision early. The individualized DNR program needs to be developed according to the needs of cancer patients.

Although race and ethnic background are known to be important factors in the completion of advance directives, there is a dearth of literature specifically investigating the effect of race and ethnicity on advance directive completion rate after palliative care consultation (PCC).

A chart review of all patients seen by the PCC service in an academic hospital over a 9-month period was performed. Data were compiled using gender, race, ethnicity, religion, and primary diagnosis. For this study, advance directives were defined as: “Do Not Resuscitate” (DNR) and/or “Do Not Intubate” (DNI).

Of the 400 medical records reviewed, 57% of patients were female and 71.3% documented their religion as Christian. The most common documented diagnosis was cancer (39.5%). Forty-seven percent reported their race as white. White patients completed more advance directives than did nonwhite patients both before (25.67% vs. 12.68%) and after (59.36% vs. 40.84%) PCC. There was a significantly higher proportion of whites who signed an advance directive after a PCC than of nonwhites (p = 0.021); of the 139 whites who did not have an advance directive at admission, 63 signed an advance directive after a PCC compared with 186/60 nonwhites (45% vs. 32%, respectively, p = 0.021). Further analysis revealed that African Americans differed from whites in the likelihood of advance directive execution rates pre-PCC, but not post-PCC.

This study demonstrates the impact of a PCC on the completion of advance directives, on both whites and nonwhites. The PCC Intervention significantly reduced differences between whites and African Americans in completing advance directives, which have been consistently documented in the end-of-life literature.
