How many physician referrals is too many?

Most clinical review articles about health conditions that may require co-management of specialist physicians contain a short section or Table titled "Indications for Referral." For example, a recent article on prevention and care of outpatient burns includes a list of criteria from the American Burn Association for considering the transfer of a patient to a burn center. This and other lists generally represent expert consensus on appropriate reasons to refer a patient in a typical primary care setting; obviously, availability and accessibility of specialists has a large influence on a family physician's practice with regard to management of "referable" conditions. Clinicians' training and expertise also affect their comfort levels in caring for patients with complex problems and, as previous studies have shown, these factors lead to variations in referral rates.

Despite variations in referral rates among individual physicians, there is a clear trend in the U.S. toward more referrals. An analysis of ambulatory care survey data from 1999 to 2009 recently published in the Archives of Internal Medicine found that the probability that an office visit resulted in a referral nearly doubled during this time period, from 4.8% to 9.3%. It isn't clear why this is happening, or what percentage of those referrals are appropriate. Medicine may be becoming more complex, or patients may be presenting with more problems that cannot be effectively dealt with in an office visit that is the same length as it was 10 years ago.

What is clear is that at a time when a coalition of national primary and specialty care organizations is leading a campaign to reduce overuse of health care resources, the impact of this dramatic increase in referrals cannot be ignored. But in the absence of evidence-based standards for when to refer, how many referrals is too many? Is this even an answerable question? And if it is, what can be done about it?

  1. When primary care physicians have less time per patient to spend with each patient, I suspect, their referral rates rise. According to the Group Health study when the physicians spend more time per patient for the standard office visit, the referral rates, patient use of the ER, hospital admission rates all drop. These rates drop significantly. The more efficiency in a primary care office visit is stressed, the less the opportunity for human encounters. The quality and quantity of the human encounter in primary care is the core ingredient.
