Nurses screening for skin cancer: an observation study.

Skin cancer rates in Australia are the highest in the world and it is an important cause of mortality and morbidity. Screening is a method of control for skin cancer/melanoma through early diagnosis and prompt referral and treatment. To date, there have been no controlled trials evaluating the impact of screening on morbidity and mortality, and hence insufficient evidence to recommend for or against routine screening for skin cancer/melanoma by primary care providers. Australian health authorities have called for studies that investigate the viability of using trained observers apart from medical practitioners--such as nurses, pharmacists and physiotherapists--in opportunistic screening for skin cancer in populations that have a high prevalence of these skin cancers, largely on the basis of cost arguments. We conducted a double blind observation screening study comparing the performance of nurses to those plastic surgeons participating in a skin cancer screening program. The role of the nurse in this program was not to diagnose skin cancer, but to not miss lesions that required further specialist examination. Measurements were recorded for 256 screenees. Plastic surgeons issued 77 (30%) individual referrals for lesions suspicious of being skin cancer. Nurse observations noted 73 (95%) of these 77 cases. The case for the pre-screening of large populations for skin/cancer by trained nurses warrants further attention.
