Objectives: Despite the increasing utilization of in-home services, the
assessment of in-home services used by those that have certified levels of care needs has
been limited to the actual changes in individual outcomes. The purpose of the present
study was to determine factors affecting how the utilization of in-home services could
have sustained and/or improved or deteriorated the care needs levels of frail persons. We
also examined the effect of in-home services used in the lower level of care needs
subgroup and the higher level of care needs subgroup during a two-year period.Subjects and Methods: We used longitudinal data from Izumo City of those
individuals with certified levels of care needs to analyze the changes in care need levels
in Izumo City between 2002 to 2004. In 2002, 2,651 persons had certified levels of care
needs. All permanent residents of care facilities, at care needs level 5 in 2002, those
who died since 2002 and people who could not be traced during the two-year follow-up
period were excluded. The remaining data from 1,788 frail persons were ultimately
analyzed. We arbitrarily divided the changes in care needs levels into two categories:
sustained/improved and deteriorated. The care needs levels were also stratified into a
lower level of care needs subgroup and a higher level of care needs subgroup at the
baseline. Simple statistical analysis and binary logistic regression analysis were used to
analyze factors that were thought to be related to in-home service utilization data to
predict changes in care needs levels.Results: Approximately 63.3% of the respondents had a sustained or improved
care needs level, and 36.7% of the respondents showed deteriorated of care needs levels.
In the lower level of care needs subgroup, utilization of home help/bathing (OR=2.59) was
associated with significant sustained/improved care needs levels. In the higher level of
care needs subgroup, day care service (OR=0.90) and short stay services (OR=0.87) were
significantly related to deteriorated care needs levels, respectively.Conclusions: This study shows that home help/bathing care in the lower level
of care needs subgroup was a significant predictor of sustained/improved levels of care
needs for frail persons but that short stay services and day care services in the higher
level of care needs subgroup have a negative impact on sustained/improved levels of care
needs. Our results suggest that utilization of home help services can prevent
deterioration of these levels of care needs in frail persons.
