PD in humans is therefore thought to be a function of genetic predisposition, potentially associated with how efficiently an individual is able to metabolize dopamine-related neurotoxins.
This model suggests that people's use of health services, or NHA, is a function of their predisposition to use services, factors which enable or impede use, and their need for care.
These outcomes are a function of the predisposition (to utilise the healthcare service) and enabling or impeding factors (to utilise the healthcare service) and perceived and objective need (to utilise the healthcare service).
Specifically, Andersen's model assumes that individuals' use of services is a function of their predisposition to use services (predisposing factors), factors that support or impede use (enabling factors), as well as their need for health care (illness level).
We developed the telephone interview survey on the basis of a conceptual framework derived from Andersen's Behavioral Theory of HealthCare Utilization (8), which suggests that a patient's use of health services is a function of their predisposition to use services, factors that enable or impede use, and their need for care.
In the model which has been discussed and continuously refined over the years [ 8- 10], it is assumed that individuals' use of services is a function of their predisposition to use services (predisposing factors), factors that support or impede use (enabling factors), as well as their need for health care (illness level).
All these types of problems are developmental and are more a function of hereditary predispositions (genetics) then your foot mysteriously getting bigger or waking up one morning with a bony prominence you never had before.
According to the model a person's utilization of health services is a function of his/her need for such services, a predisposition to use them and factors that enable them to be used.
Each individual is characterized by a PMRN that describes it genetic predisposition to mature as a function of its age and length.
We speculate that the significant differences in enrollment rates by clinic site were a function of the recruitment skills of the RSs and the predisposition of the potential participants.
