Emergency transfers of home care patients in Fukui Prefecture, Japan: A retrospective observational study

Prognostic Biomarkers of Mortality in Older Patients Without Cancer in Home Healthcare

Introduction The number of patients without cancer who receive home healthcare is increasing; however, prognostic prediction is challenging among them. This study aimed to investigate the prognostic value of generic biomarkers for mortality in patients without cancer who receive home healthcare. Materials and methods The multicenter retrospective cohort study included 114 older patients without cancer, of which 12 (10.5%) died during the study period. The median (interquartile range (IQR)) of the study observation period was 181 (49-293) days. Generic biomarkers included hemoglobin (Hb), albumin (Alb), C-reactive protein (CRP), estimated glomerular filtration rate (eGFR), aspartate aminotransferase (AST), and alanine aminotransferase (ALT). A multivariate-adjusted Cox proportional hazard model on all-cause mortality was used to calculate hazard ratio (HR) and 95% confidence interval (95% CI) for each biomarker. The cut-off values of each biomarker were calculated by receiver operating characteristic curve analysis. The performance of cut-off values was evaluated by time-dependent area under the curves (AUCs). Results The median (IQR) of AST was 13 (10-21) U/L. The biomarkers significantly predictive of mortality were Hb (fully adjusted HR: 0.41; 95% Cl: 0.25 - 0.70), Alb (HR: 0.41; 95% Cl: 0.02 - 0.69), and AST (HR: 1.09; 95% Cl: 1.00 - 1.18), along with male sex (HR: 4.07; 95% Cl: 1.15 - 14.35). The AUC of a cut-off value of AST (> 31 U/L) at 360 days was 0.72 (95% CI 0.71 - 0.72; p < 0.01), which outperformed the AUCs for Hb and Alb. Conclusion AST, in addition to Hb and Alb, may be useful for predicting the prognosis of older patients without cancer, who had a normal-to-mild increased level of AST, in home healthcare settings. Larger-sample and longer follow-up studies will be warranted.

Cross-Sectional Study on Risk of Flooding and Landslides and Their Associated Perceptions Among Home Health-Care Patients Living in Fukui Prefecture, Japan

OBJECTIVE

This study aimed to evaluate a risk of flooding and landslides among home-care patients, to reveal an extent to which patients require support for evacuation, and to determine whether risk was accurately perceived among the patients.

METHODS

This is a cross-sectional study targeting the patients who were actively treated at the home-care clinic in Fukui Prefecture, Japan. We collected data on the patients' sociodemographic and clinical characteristics. Additionally, we collected data on their risk of flooding and landslides through hazard maps and distributed a questionnaire to these patients regarding their risk awareness of flooding and landslides.

RESULTS

Of the 199 eligible home-care patients, 84.9% (169 of 199) were at risk of flooding and/or landslides, and 58.6% (99 of 169) of them needs support during evacuation. Furthermore, of those who were at risk of flooding and/or landslides, 46.0% (45 of 99) had accurate risk assessments. Factors that resulted in inadequate risk awareness of flooding and landslides included: not placing importance on evacuation, not using medical equipment, and living on the first floor.

CONCLUSIONS

There was limited risk awareness of flooding and/or landslides among the home-care patients. The information of the risk factors regarding inadequate risk awareness of flooding and landslides should be used to sophisticate flooding and landslides evacuation strategy.
