"Screening for Cancer:
Screening strategies are often used to find cancer before there are symptoms. Many d ifferen t strategies are available. Screening strategies require balancing tradeoffs am ong benefit, harms, and costs. Some cancer screening strategies are sim ple and effective and cause few harms. However, o the r screening strategies may not be needed, are ineffective, or offer to o few benefits fo r the associated harms and costs. It is im p orta nt fo r patients to understand the benefits and harms o f screening strategies and discuss these with th e ir doctor.
Advice for High-Value Care From the American College of Physicians." It is in the 19 May 2015 issue of Annals o f Internal Medicine (volume 162, pages 718-725). The authors are T.J. Wilt, R.P. Harris, and A. Qaseem, for the High Value Care Task Force of the American College of Physicians.
H ow d id th e ACP d evelop th is advice? The Am erican C ollege o f Physicians (ACP) reviewed clinical guidelines and research from d ifferen t organizations. The authors looked at data about deaths and illnesses from cancer and harms related to screening strategies. Using this inform ation, they gave advice about which strategies should be used to screen fo r com m on types of cancer in adults.
H ow do w e k n o w w h eth er can cer scr een in g is o f h igh v a lu e to a p erson ? • High-value screening strategy: a strategy th a t offers benefits that make the harms and costs w orthw hile. For a strategy to be high-value, it must also lead to better outcomes, such as reducing cancer deaths. For some patients, fin d in g cancer early with screening does not necessarily mean th a t th e ir lives w ill be extended or cancer death will be prevented. • Low-value screening strategy: a strategy in which benefits do not outw eigh the harms and costs. Value is not the same as cost. For example, a screening strategy with a high cost may be high-value because it provides large benefits and few harms. Some low-cost strategies are lower-value because they do not provide enough benefits and may even be harmful. Personal values or preferences may also influence the value o f a screening strategy to th a t person. acp
