Perceptions of Palliative Care: Demographics and Health Status Among the General Population in Florida and the United States.

BACKGROUND: Palliative care (PC) helps maintain quality of life for seriously ill patients, yet, many Americans lack knowledge of PC. AIM: To explore the relationships between knowledge of PC of individuals living in north-central Florida and throughout the United States. DESIGN: This cross-sectional survey with three sampling approaches, one was a community-engaged sample and two were panel respondent samples. Respondents and setting: Respondents of the Florida sample (n1 = 329) and the community-engaged sample (n2 = 100), were representative of the 23 Florida county general population. Respondents of the national sample (n = 1800) were adult members of a panel owned by a cloud-based survey platform. RESULTS: Young adults compared with adults (OR 1.62, 95% CI 1.14-2.28, P .007), middle-adults (OR 2.47, 95% CI 1.58-3.92, P < .001) and older-adults (OR 3.75, 95% CI 2.50-5.67, P < .001) were less likely to agree that the goal of PC is to help friends and family cope with a patient's illness, and that the goal of PC is to manage pain and other physical symptoms compared with adults (OR 1.67, 95% CI 1.20-2.30, P .002) middle-adults (OR 2.58, 95% CI 1.71-3.95, P < .001) and older-adults (OR 7.19, 95% CI 4.68-11.2, P < .001). Participants with greater rural identity (OR 1.39, 95% CI 1.31-1.48, P < .001) were more likely to agree that accepting PC means giving up. CONCLUSIONS: Increased knowledge of PC might be influenced through targeting educational interventions and educating the general population through social media use.

Personalized Tacrolimus Dosing After Liver Transplantation: A Randomized Clinical Trial.

Background: Inter- and intra-individual variability in tacrolimus dose requirements mandates empirical clinician-titrated dosing that frequently results in deviation from a narrow target range. Improved methods to individually dose tacrolimus are needed. Our objective was to determine whether a quantitative, dynamically-customized, phenotypic-outcome-guided dosing method termed Phenotypic Personalized Medicine (PPM) would improve target drug trough maintenance. Methods: In a single-center, randomized, pragmatic clinical trial ( NCT03527238 ), 62 adults were screened, enrolled, and randomized prior to liver transplantation 1:1 to standard-of-care (SOC) clinician-determined or PPM-guided dosing of tacrolimus. The primary outcome measure was percent days with large (>2 ng/mL) deviation from target range from transplant to discharge. Secondary outcomes included percent days outside-of-target-range and mean area-under-the-curve (AUC) outside-of-target-range per day. Safety measures included rejection, graft failure, death, infection, nephrotoxicity, or neurotoxicity. Results: 56 (29 SOC, 27 PPM) patients completed the study. The primary outcome measure was found to be significantly different between the two groups. Patients in the SOC group had a mean of 38.4% of post-transplant days with large deviations from target range; the PPM group had 24.3% of post-transplant days with large deviations; (difference -14.1%, 95% CI: -26.7 to -1.5 %, P=0.029). No significant differences were found in the secondary outcomes. In post-hoc analysis, the SOC group had a 50% longer median length-of-stay than the PPM group [15 days (Q1-Q3: 11-20) versus 10 days (Q1-Q3: 8.5-12); difference 5 days, 95% CI: 2-8 days, P=0.0026]. Conclusions: PPM guided tacrolimus dosing leads to better drug level maintenance than SOC. The PPM approach leads to actionable dosing recommendations on a day-to-day basis. Lay Summary: In a study on 62 adults who underwent liver transplantation, researchers investigated whether a new dosing method called Phenotypic Personalized Medicine (PPM) would improve daily dosing of the immunosuppression drug tacrolimus. They found that PPM guided tacrolimus dosing leads to better drug level maintenance than the standard-of-care clinician-determined dosing. This means that the PPM approach leads to actionable dosing recommendations on a day-to-day basis and can help improve patient outcomes.
