Practice standards: the need for a personal element

With rare exceptions, guidelines for clinical practice lack a personal element that allows for physicians' varying goals and patients' differing preferences. The importance of this element is illustrated by means of four examples: 1, hormone replacement therapy for the menopause; 2, early detection of breast cancer; 3, the treatment of acute streptococcal pharyngitis and 4, the diagnosis of symptoms that do not implicate any specific organ system. The advantages and disadvantages of guidelines are pointed out. Among the advantages are their usefulness as standards for audit and the fact that, in the process of reaching consensus, personal experience is taken into consideration. Chief among the disadvantages is their possible misuse by people outside of the profession. It is concluded that guidelines can be improved if their recommendations consider individual goals and preferences. They can become more influential if attention is paid to their proper dissemination.
