Effectiveness of initiating advance care planning among older outpatients through intervention by physicians trained in a model discussion video: A randomized controlled trial.

AIM: This study aimed to assess the impact of a physician-led intervention on advance care planning (ACP) introduction among older outpatients using a model discussion video. METHODS: This prospective interventional study included Japanese general practice outpatients aged ≥65 years. All participants received an ACP leaflet. Co-researchers were trained using a model discussion video based on the "Serious Illness Conversation Guide," and provided ACP introduction explanations to the intervention group to ensure intervention content consistency. The control group received the ACP leaflet only, with no standardized explanations. The primary outcome was ACP discussion occurrence. Secondary outcomes included ACP engagement (assessed through the 4-item ACP Engagement Survey), engagement score for advance directives acquisition and score for surrogate decision-maker identification, and anxiety incidence (assessed through Generalized Anxiety Disorder-7). RESULTS: This study included 48 participants: 25 (52.1%) in the intervention group and 23 (47.9%) in the control group. Regarding primary outcome, the intervention group had significantly more ACP discussions compared with the control group (92.0% vs 26.1%, adjusted odds ratio 50.2, P = 0.0012). Regarding secondary outcomes, the intervention group showed greater readiness (mean scores for the 4-item Engagement Survey [P = 0.0001], engagement score for advance directives acquisition [P = 0.01] and score for surrogate decision-maker determination [P = 0.03]) than the control group, without increasing anxiety. CONCLUSIONS: This physician-led ACP introduction for older patients in a Japanese general practice setting enhanced ACP readiness and stimulated discussions, without increasing anxiety. The model discussion video for ACP introduction might effectively train physicians in general practice settings. Geriatr Gerontol Int 2024; ••: ••-••.

Validation study of EuroSCORE II for dialysis patients: A single-center study in Japan.

BACKGROUND: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II is a predictive model for in-hospital mortality after cardiac surgery. Although it has good performance among the general population undergoing cardiac surgery, it has not been validated among dialysis patients, who have a higher rate of mortality after cardiac surgery. This study aimed to evaluate the performance of the model in predicting in-hospital mortality in maintenance dialysis patients undergoing cardiac surgery. METHODS: This retrospective, single-center study included adult patients on maintenance dialysis who underwent open cardiac surgery at our institution. Calibration performance of EuroSCORE II for in-hospital death was determined based on the comparison between expected and observed mortalities for low- (EuroSCORE II <4 %), intermediate- (4-8 %), and high-risk (>8 %) groups. The area under receiver operating characteristic curve (AUROC) was investigated to determine the model's discrimination performance. RESULTS: A total of 163 patients (male, 73.6 %; median age, 70 years; median dialysis vintage, 9 years; median EuroSCORE II, 3.3 %) were included. The mortality rate was 9.2 %. The observed mortality rates (vs. mean expected mortality) rates were 2.1 % (vs. 2.4 %), 7.5 % (vs. 5.5 %), and 34.5 % (vs. 21.1 %) in the low-, intermediate-, and high-risk groups, respectively. Its AUROC was 0.825 (95 % confidence interval, 0.711-0.940). CONCLUSIONS: Although EuroSCORE II model adequately estimated in-hospital mortality in the low-and intermediate-risk groups (EuroSCORE II <8 %), it underestimated in-hospital mortality in the high-risk group (EuroSCORE II >8 %) among maintenance dialysis patients. The discrimination performance of the model for in-hospital death was good among maintenance dialysis patients.

Impact of antibiotic timing relative to percutaneous aspiration on culture positivity rate and clinical outcomes: A retrospective study of patients with pyogenic liver abscess.

The optimal timing of antibiotic administration relative to liver abscess aspiration is debatable. This retrospective cohort study investigated whether the timing affects the abscess culture positivity rate and clinical outcomes. Twenty-nine patients with 30 percutaneously drained liver abscess cases were analyzed. Antibiotics were administered before aspiration (pre-aspiration antibiotics) in 22 cases and following aspiration (post-aspiration antibiotics) in 8 cases (i.e., 1 patient underwent aspiration twice, both before and following antibiotics). Both groups demonstrated similar patient characteristics, short time to aspiration, and high antibiotic appropriateness. Most patients were immunocompetent and non-septic. Pre-aspiration antibiotics did not reduce the culture yield (95% with pre-aspiration antibiotics vs. 100% with post-aspiration antibiotics; p = 1). Post-aspiration antibiotics were not associated with higher mortality, longer length of hospitalization, or an increased rate of clinical deterioration following aspiration. With appropriate antibiotic and aspiration, antibiotics timing can be either before or after aspiration without compromising the culture positivity rate and clinical outcomes.
