A typology of service patterns in end-stage AIDS care: relationships to the transprofessional model.
OBJECTIVE
To determine the relationship among 11 types of home health care services for patients with HIV/AIDS and to develop a terminal-care, service-usage profile of persons receiving such services. Services include the number of psychiatric nurse visits, Medical Social Work (MSW) visits, evaluation visits, physical therapy visits, occupational therapy visits, homemaker visits, home health aide visits, public health nurse visits, registered nurse (RN) visits, Licensed Vocational Nurse (LVN) visits, and Intravenous (i.v.) nurse visits.


METHODS
Data were collected on 549 AIDS patients admitted for medical/surgical home-care services to the Visiting Nurse Association of Los Angeles (VNA-LA). The service utilization data were collected from the VNA-LA's computerized data system.


METHODS
The relationship among the service types was evaluated with principal component analysis. A service-usage profile was developed for patients using cluster analysis. To control for the variability in the amount of time that patients were on service, the number of days that patients were in the VNA-LA program and were actually receiving services was included as a factor that yielded a variable reflecting the number of each type of service that a patient received per day.


RESULTS
Five components were found to best describe the relationships among the service-type variables. These were identified as being: the Number of Evaluation Visits, the Number of Intensive Nursing Visits, the Number of Physical Therapy Visits, the Number of Psychosocial Visits, and the Number of Attendant Visits. Patients were found to cluster into 1 of 5 groups based on the type of service utilization profile that they received. The variables that appeared to have the most influence on this profile were the number of home health aide visits per day that the patient received, the number of RN visits that were made, the number of i.v. nurse visits that were provided, and the number of LVN visits that were made.


CONCLUSIONS
Terminally ill AIDS patients receiving home health care services can be identified as having a service utilization profile. This profile can be used to evaluate more precisely the service areas in which costs for patient services differ. Individually assigned to an experimental Transprofessional Model of care had a different service utilization profile than those assigned to a Traditional Model of care.
