18563 Background: Cancer care providers frequently discuss AD with their patients. The providers’ own attitudes toward end-of-life planning likely influence the choices and actions of their patients. We investigated the prevalence of written AD among the care providers at our community-based cancer center. Methods: All cancer center employees who have face-to-face contacts with patients (N=170) were sent an email survey in October 2005. This included medical (physicians, 15), associate (physician assistants and nurse practitioners, 7), and support (nurses, radiation therapists, medical or nurse assistants, and patient liaisons; 148) staffs. We collected data on demographics, work history, and AD. Results: A reply was obtained from 136 (80%) individuals. There were more females (90.2%) and the median age was 43 years (range, 20–63). While 82.8% reported to have discussed their wishes regarding future life-sustaining medical care with those closest to them, only 35.1% had a written AD: medical (58.3%), associate (50%), and support staffs (32.2%). Among those with AD, only 66% had made their own care providers aware of this. The top 5 factors that influenced providers whether to have or not to have AD were: experience at work (36.6%), spouse/domestic partner (25.4%), time to complete written AD (23.9%), family members/friends (21.6%) and children (19.4%). Interestingly, no one considered medical condition or illness as a factor. Increased age was significantly associated with having AD (odds ratio: 1.068; 95% CI:1.029–1.108), while the sex, number of years working with cancer patients, provider role, and marital/living status were not. Among the medical and associate staffs, 55.6% reported routinely discussing AD with their patients. Although all medical/associate staffs rated themselves as knowledgeable about and comfortable with discussing AD, the group who had AD was more apt to rate themselves as very knowledgeable and very comfortable. Conclusions: Only about a third of all cancer care providers and about half of cancer physicians at our institution have a written AD. Despite work experience with a patient population having a high mortality rate, cancer care providers do not adequately communicate end-of-life planning to their own health care providers. No significant financial relationships to disclose.
