problem in which time is allowed to pass before medical intervention or therapy is used. During this time, repeated testing may be performed. Related terms include ''expectant management'', ''active surveillance'' (especially active surveillance of prostate cancer), and ''masterly inactivity''. The term ''masterly inactivity'' is also used in nonmedical contexts. A distinction can be drawn between ''watchful waiting'' and ''medical observation'', but some sources equate the terms. Usually, watchful waiting is an outpatient process and may have a duration of months or years. In contrast, medical observation is usually an

Medical uses

Often watchful waiting is recommended in situations with a high likelihood of self-resolution if there is high uncertainty concerning the diagnosis, and the risks of intervention or therapy may outweigh the benefits. Watchful waiting is often recommended for many common illnesses such as

or other protocol to ensure a timely transition from watchful waiting to another form of management, as needed. This is particularly common in the post-surgical management of cancer survivors, in whom cancer recurrence is a significant concern.

Medical observation

Usually, patients in observation, according to hospital policy, are kept in observation for only 24 or 48 hours before they will be discharged or admitted as an inpatient. Insurance can play a role in how "observation" is defined (for example, US Medicare does not support observation services for over 48 hours).
