Use of Big Medical Data

 For planning and evaluating medical policies, it is important to more accurately grasp the actual medical situation in Motoichi. However, the published existing materials are tabulated in a wide area such as city units, and the actual situation of each area is often unknown. For this reason, Yokohama City is independently working on the analysis of medical big data as an initiative to formulate policies based on evidence (EBPM, Evidence Based Policy Making). 

Final update date February 16, 2021

YoMDB Analysis

 YoMDB (Yokohama Agricultural Data Base) aggregates medical, nursing and health data held by the city for use in medical policies, deletes personal information as much as possible, and converts it into a database (operation from March 2018) ).

Results of analysis using YoMDB NEW!

 We analyzed the use of home healthcare using YoMDB and multiplied the future population estimation of Yokohama City to estimate the future of home healthcare demand. As a result, it has been found that demand will double in the next 20 years.

 An academic paper summarizing the results was published in an international magazine in November 2018.

 

 We analyzed cancer patients who received terminal care at home. This has shown the actual situation of home terminal care patients, such as the number of emergency home visits. In addition, the survival period after the transition to home has been clarified.

 The results were presented at the 2nd Japan Clinical Epidemiological Society held in September 2018 and the 61st Japanese Society of Gynecological Oncology held in July 2019.

 

 2 The percentage of diabetic nephropathy in patients with type 2 diabetes of insurers (National Health Insurance / Late) was clarified in Real World Data. The results were announced at the 78th Japan Society of Public Health in October 2019.


Analysis of NDB

 Using NDB (information database such as receipt information and specific physical checkup of medical big data, was used to compile a report on the results of analyzing the actual conditions of cancer treatment performed at city medical institutions. The analysis was conducted jointly with Yokohama City University.

A summary of the analysis results report is as follows.


Overview of Analysis

 Using NDB data, we analyzed patients who received cancer treatment (drug therapy, surgical therapy, radiation therapy) at medical institutions in the city from April 2014 to March 2016.

 

Major Analysis Results

  • Approximately 52,000 people were receiving cancer treatment at a city medical institution annually.
  • In the working generation, women were treated twice as many as men. In the elderly, men were treated 1.5 times more than women.
  • In cancer treatment, nearly 70% of patients received pharmacotherapy.
  • Nearly 70% of patients over the age of 80 were undergoing chemotherapy.
  • The average period of outpatient chemotherapy was about 4.5 months, and the frequency of administration was 85% or less twice a month.
  • Of the working generations, an average of 13.8 visits were required per year for cancer patients undergoing outpatient chemotherapy.
    In addition, 74% of patients went to the hospital more than 10 times a year, and 18% of patients went to the hospital more than 20 times a year.

  

Consideration of Analysis Results

  • The comprehensive analysis focusing on patients who have been treated for cancer has a new perspective, and for the first time revealed the actual situation of patients being handled by medical institutions in the city.
  • The proportion of patients undergoing chemotherapy is higher than that of surgical and radiation therapy, and it has been found that chemotherapy plays a major role in cancer treatment.
  • It can be an important basic data for flexible system design to balance work and treatment.
  • Regarding palliative care, general wards and home-based data were not included, and the actual situation was not grasped.
