title: Physician knowledge and practice patterns relating to diabetic nephropathy.
abstract: OBJECTIVE
  To assess the knowledge and practice patterns of primary care physicians relating to the detection and treatment of diabetic nephropathy and to compare these findings with current standards of care.
  
  
  METHODS
  National survey.
  
  
  METHODS
  1,000 randomly selected physicians.
  
  
  METHODS
  Primary care.
  
  
  METHODS
  Mailed questionnaire consisting of a six-page "Diabetes Survey."
  
  
  RESULTS
  Among the 1,000 primary care physicians, 950 were considered eligible for the survey. Sufficiently completed surveys were returned by 216 physicians, yielding an adjusted response rate of 22%. In general, patients with type 1 diabetes were monitored more intensively than those with type 2 diabetes. Primary care physicians were more likely to monitor patients for overt proteinuria (86%) than microalbuminuria (58%). Of the physicians who claimed to monitor patients for microalbuminuria, 39% chose inappropriate methods for detection, which lowers the percentage of physicians who correctly monitored for microalbuminuria to 37%. More than 95% of the respondents were aware of the benefits of angiotensin-converting enzyme inhibitors (ACEIs) in delaying the progression of diabetic nephropathy. Patients with proteinuria (86%) were more likely to be treated with an ACEI than were patients with microalbuminuria (79%). If a patient presented with proteinuria but without hypertension, the use of ACEIs fell to 75%. Rates of referral to a nephrologist were low at early stages of the disease (3% to 11%) and remained relatively low (28%) at later stages, even when serum creatinine was greater than 3 mg/dL.
  
  
  CONCLUSIONS
  Further efforts directed toward education of primary care physicians about diabetic nephropathy have the potential to improve the care of patients with this disorder. These findings demonstrate a unique opportunity for pharmacists to become educators to physicians in their community.
