Five types of home-visit nursing agencies in Japan based on characteristics of service delivery: cluster analysis of three nationwide surveys

Background

The number of home-visit nursing agencies in Japan has greatly increased over the past 20 years since the Japanese government first introduced it in 1992 to meet the increased needs of home-bound elderly. Since then, home-visit nursing has come to serve for a variety of populations such as those with terminal-stage cancer, neurological diseases, psychiatric conditions, or children with chronic conditions; currently the number of agencies has reached 6,801 (as of April 2013). Yet little has been known about the details of their characteristics in terms of patient types or differences/similarities across regions. In this study, we developed a method to categorize home-visit nursing agencies throughout Japan based on their actual service delivery, in order to help improve healthcare policies allowing better services by those agencies.

Methods

We performed a cluster analysis on data from two national databases (Survey of Institutions and Establishments for Long-term Care which is annually administered by the Ministry of Health, Labour and Welfare [dataset 1; n?=?5,161] and Information Publication System for Long-term Care which is annually reported by home-visit nursing agencies to their respective prefectural governments [dataset 2; n?=?4,400, matching rate to data set 1: 84.4%]), in addition to the results from our original nationwide Fax survey of the service delivery system of home-visit nursing agencies (dataset 3; n?=?2,049 matching rate to data set 1: 39.3%).

Results

The cluster analysis suggested five categories for home-visit nursing agencies based on the type of service delivery system. For deciding of these categories, we held 13 panel discussions with specialists to confirm that the categorization of the home-visit nursing agencies appropriately reflected their actual delivery systems. The five categories were: nurse-centered (560, 10.9%), rehabilitation-centered (211, 4.1%), psychiatric-centered (360, 7.0%), urban-centered (1,784, 34.5%), and rural-centered (2246, 43.5%).

Conclusions

This five categorization system of home-visit nursing agencies could ensure appropriate healthcare policies that will allow agencies to provide better home-visit nursing services based on their patient and staff characteristics and regional needs. The findings would be valuable both in Japan as well as in other countries with rapidly growing aging populations.
