For decades, doctors in picturesque Boise, Idaho, were part of a tight-knit community, freely referring patients to the specialists or hospitals of their choice and exchanging information about the latest medical treatments.

But that began to change a few years ago, when the city’s largest hospital, St. Luke’s Health System, began rapidly buying physician practices all over town, from general practitioners to cardiologists to orthopedic surgeons.

Today, Boise is a medical battleground.

A little over half of the 1,400 doctors in southwestern Idaho are employed by St. Luke’s or its smaller competitor, St. Alphonsus Regional Medical Center.

Many of the independent doctors complain that both hospitals, but especially St. Luke’s, have too much power over every aspect of the medical pipeline, dictating which tests and procedures to perform, how much to charge and which patients to admit.

In interviews, they said their referrals from doctors now employed by St. Luke’s had dropped sharply, while patients, in many cases, were paying more there for the same level of treatment.

Boise’s experience reflects a growing national trend toward consolidation. Across the country, doctors who sold their practices and signed on as employees have similar criticisms. In lawsuits and interviews, they describe growing pressure to meet the financial goals of their new employers — often by performing unnecessary tests and procedures or by admitting patients who do not need a hospital stay."

"Regulators expressed some skepticism about the results, for patients, of rapid consolidation, although the trend is still too new to know for sure. “We’re seeing a lot more consolidation than we did 10 years ago,” said Jeffrey Perry, an assistant director in the F.T.C.’s Bureau of Competition. “Historically, what we’ve seen with the consolidation in the health care industry is that prices go up, but quality does not improve.”

"But the consolidation of health care may be coming at a hefty price. By one estimate, under its current reimbursement system, Medicare is paying in excess of a billion dollars a year more for the same services because hospitals, citing higher overall costs, can charge more when the doctors work for them. Laser eye surgery, for example, can cost $738 when performed by a hospital-employed doctor, compared with $389 when done by an unaffiliated doctor, according to national estimates by the independent Congressional panel that oversees Medicare. An echocardiogram can cost about twice as much in a hospital: $319, versus $143 in a doctor’s office."
