Reduced utilization and cost of primary care clinic visits resulting from self-care education for patients with osteoarthritis of the knee.
To determine the extent to which the cost of an effective self-care intervention for primary care patients with knee osteoarthritis (OA) was offset by savings resulting from reduced utilization of ambulatory medical services.
In an attention-controlled clinical trial, 211 patients with knee OA from the general medicine clinic of a municipal hospital were assigned arbitrarily to conditions of self-care education (group E) or attention control (group AC).
Group E (n=105) received individualized instruction and followup emphasizing nonpharmacologic management of joint pain.
Group AC (n=106) received a standard public education presentation and attention-controlling followup.
A comprehensive clinical database provided data concerning utilization and cost of health services during the following year.
Only 25 subjects (12%) were lost to followup.
The 94 subjects remaining in group E made 528 primary care visits during the year following intervention, compared with 616 visits by the 92 patients remaining in group AC (median visits 5 versus 6, respectively ; P<0.05).
Fewer visits translated directly into reduced clinic costs in group E, relative to controls (median costs [1996 dollars] $229 versus $305, respectively ; P<0.05).
However, self-care education had no significant effects on utilization and costs of outpatient pharmacy, laboratory, or radiology services over the ensuing year. (...)
