A Cost Projection of Scheduled Physician Home-Visit Services in Japan: 2014 to 2064.

This study predicts the volume and spending on scheduled physician home-visit (SPHV) services over five decades. This model-based evaluation study considered the following scenarios in Japan: (1) change in services-delivery; (2) technology-assisted services; (3) a combination of (1) and (2). The model predicted that the volume and spending on SPHV will increase as the population and working-age population decline. Scenario analysis indicated that a combined strategy could reduce the relative rate of spending to less than 2.00 in 2064, indicating that home health-care service reforms through changes in services-delivery and cost-reduction through technology-assisted services are promising in countries facing aging population.

Impact of dynamic parameter of trends in vital signs on the prediction of serious events in hospitalized patients -a retrospective observational study.

Aim: Although early detection of patients' deterioration may improve outcomes, most of the detection criteria use on-the-spot values of vital signs. We investigated whether adding trend values over time enhanced the ability to predict adverse events among hospitalized patients. Methods: Patients who experienced adverse events, such as unexpected cardiac arrest or unplanned ICU admission were enrolled in this retrospective study. The association between the events and the combination of vital signs was evaluated at the time of the worst vital signs 0-8 hours before events (near the event) and at 24-48 hours before events (baseline). Multivariable logistic analysis was performed, and the area under the receiver operating characteristic curve (AUC) was used to assess the prediction power for adverse events among various combinations of vital sign parameters. Results: Among 24,509 in-patients, 54 patients experienced adverse events(cases) and 3,116 control patients eligible for data analysis were included. At the timepoint near the event, systolic blood pressure (SBP) was lower, heart rate (HR) and respiratory rate (RR) were higher in the case group, and this tendency was also observed at baseline. The AUC for event occurrence with reference to SBP, HR, and RR was lower when evaluated at baseline than at the timepoint near the event (0.85 [95%CI: 0.79-0.92] vs. 0.93 [0.88-0.97]). When the trend in RR was added to the formula constructed of baseline values of SBP, HR, and RR, the AUC increased to 0.92 [0.87-0.97]. Conclusion: Trends in RR may enhance the accuracy of predicting adverse events in hospitalized patients.
