Relationships among HMO hospital utilization, physician visits, and years operational.
Statistical tests are performed on the membership of HMOs for which data are available (N = 124) to determine if (1) hospital utilization by HMO members is correlated with physician visits, (2) hospital utilization is correlated with the number of years a HMO is operational, and (3) physician visits is correlated with the number of years a HMO is operational. Statistical tests indicate that there is no correlation among the three pairs of variables.
