Patterns of preventive practice in New Brunswick

Abstract

A survey of active general practitioners was conducted in New Brunswick to ascertain their patterns of preventive practice with respect to cancer of four anatomic sites: the breast, the cervix, the colon and rectum, and the lung. Ninety-two percent of the physicians reported that they taught breast self-examination to their female patients, 98% that they performed breast examinations, 98% that they did Papanicolaou smears routinely, and 97% that they provided counselling against smoking. Few of the physicians reported that they submitted women aged 50 to 59 years to annual mammography (3%) or examined stool samples from asymptomatic patients over 44 years of age for occult blood (20%). Many (77%) said they still routinely performed chest roentgenography for early detection of lung cancer; an estimated 49% of the physicians said they performed cytologic screening of sputum samples for the same purpose. Preventive practices, when used, were usually carried out during major encounters with patients, such as general check-ups. The potential for prevention through this clinically based approach is still largely unrealized.
