Diagnosis And Referrals For Kidney Disease

Diagnosis And Referrals For Kidney Disease
Results of a national study of 304 U.S. physicians, in which "mock" patients' symptoms were presented for diagnosis, suggest that a sizeable percentage of primary care doctors probably fail to properly diagnose and refer patients with chronic kidney disease (CKD).

Their findings, published in the recent issue of the American Journal of Kidney Diseases, show that of 126 kidney specialists surveyed, 97 percent properly diagnosed CKD and 99 percent would have recommended specialized kidney care for the "patient." But only 59 percent of the 89 family physicians and 78 percent of 89 general internal medicine physicians fully recognized the signs and symptoms of CKD. And referrals to a nephrologist were made by only 76 percent of the family physicians and only 81 percent of general internists.

"We, as physicians, can certainly do better," says L. Ebony Boulware, M.D., Assistant Professor of Medicine at The Johns Hopkins University School of Medicine, and lead author of the study.

"Millions of people have kidney disease, but a substantial number may not have their disease recognized," Boulware added. "Simply put, our study shows that primary care physicians are not recognizing kidney disease in high-risk patients as often as they should".

In the study, the Hopkins group asked the surveyed physicians to evaluate the medical files of a simulated patient being treated by a primary-care doctor and suffering from progressive CKD. CKD is a growing epidemic, affecting an estimated 10 million Americans. The medical "record" contained clues to the condition indicating that, based on guidelines issued in 2000 by the National Kidney Foundation, the patient should be referred to a nephrologist for evaluation of CKD.

Typically ckd is characterized by the progressive loss of renal function over a period of months or years. Signs include an abnormally low glomerular filtration rate, a standard measurement of renal health. The severe form of the disease, known as end-stage renal disease, or ESRD, almost always requires dialysis, or kidney transplantation.

Boulware and her colleagues say early detection of CKD is particularly critical given that prior studies indicate that, for a number of high-risk patients, the progression of kidney disease can be markedly slowed if physicians prescribe appropriate therapies including blood pressure medications such as angiotensin converting enzyme-inhibitors or angiotensin-II receptor blocking agents.

Patients with hypertension, diabetes, or a family history of kidney disease are at increased risk of kidney disease.

The survey was mailed to a randomly generated list of doctors between August 2004 and August 2005. The questionnaire described a hypothetical scenario in which a primary care doctor was evaluating a patient with moderately reduced kidney function progressing to severely reduced kidney function. After reading the scenario, which included detailed medical information about the patient, physicians were asked, "What is your estimate of the patient's kidney function?".

Physicians were also asked which diagnostic tests they would recommend administering to the patient, and whether or not they would refer the patient to a nephrologist "at this time".

The authors cited several potential reasons why family physicians and general internists may not always spot CKD, such as lack of training to estimate kidney function and assess lab tests, lack of time and an "inadequate knowledge of CKD risk factors".

Eventhough clinical evidence suggests that early referral to a nephrologist can result in a better outcome for the patient, it is unclear whether primary care physicians who are providing appropriate care to CKD patients do any better or worse than specialists.

"A number of of these primary care doctors are in absolutely the best position to diagnose and treat chronic kidney disease," said Neil R. Powe, MD, Professor of Medicine at the Johns Hopkins School of Medicine and one of the paper's co-authors. "These health care professionals need to work with nephrologists to begin to eliminate the disagreement over how these patients should be treated and when they should be referred."
