| Outline of Annual Research Achievements |
The objective of this project has been to introduce the concept of Personalized Triage to reduce Healthcare Data Errors in Human Assisted Remote Healthcare Systems. At the first step, we investigated anthropometric growth patterns of adults (> 20 years of age). Over forty thousands health records were randomly collected by using our portable health clinic system. Incomplete records, uninterested records (young patients, age <20 years) were removed. Finally N=25,447 (male: N=13,069 and female: N=12,378) records were considered. The resulting plots comprise a series of percentile (5th, 10th, 25th, 50th, 75th, 90th, and 95th) curves that illustrate the distribution by height, weight, BMI, waist, and hip. The obtained curves were smoothened by Local Polynomial Regression (LPR). For height, there is no sharp change until the age of 49, but after the age of 50, we observe a slight decline of height and a sharp decline after the age of 80. Weight grows until the age of 49 and decline after that. Waist and Hip show similar growth characteristics with weight. A very small samples were available from old people (>80 years old). The obtained growth patterns at this age level are not representative. The study will continue to collect more samples, find growth pattern for females and compare with those of males. Once the range for age based anthropometric data is known, it will be much easier to predict measurement errors of the patients for remote healthcare systems. significant clinical growth patterns over age.

| Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
As per the plan, we designed the concept of personalized triage. There are three steps for the final implementation of the concept: (1) Human Acceptance Range (2) Group Acceptance Range (3) Personal Acceptance Range. At the first step, we completed the previously recorded data analysis to find the human acceptance range and also part of the group acceptance range.
We have already published 1 journal articles and two conference articles are accepted for presentation.
The progress is according to the plan.
|
| Strategy for Future Research Activity |
At the next step, we will test our personalized acceptance range.
We have completed two rounds of field trial to check whether the group acceptance range can detect inlier errors. The human input error was almost 13% before. After applying the group acceptance range, error rate was reduced to 2%, however some human intervention was applied. For healthcare systems, 2% is still high. We checked only anthropometric data. The challenge remains how to determine acceptance ranges for other healthcare parameters (blood pressure, blood glucose etc.)

| Causes of Carryover |
The total expenditure was executed almost according to the initial plan. Only 48,281 yen left for next year. We will use this amount for students remuneration (shakin).
