UNASSIGNED: Recent court cases in England and Wales have refocused attention on @entity1 ' decision-making capacity to consent. Little is known about the prevalence of incapacity across specialities but decision-making capacity is likely to be overestimated by clinicians. The aim of this systematic review is to estimate the prevalence of incapacity to consent to treatment or admission in different medical and @entity146 settings, and compare the two. We conducted an electronic search following PRISMA principles and included 35 studies in @entity146 and 23 studies in medical settings. The 58 included studies revealed 70 data sets across all settings. For @entity146 settings the weighted average proportion of @entity1 with incapacity was 45% (95% confidence interval (CI) 39-51%). For medical settings, the weighted average proportion of @entity1 with incapacity was 34% (95% CI 25-44%). The two groups are not significantly different from each other in terms of the proportion of incapacity (p=0.92). A considerable number of medical and @entity146 @entity1 lack capacity to make treatment and assessment decisions. Clinicians should be more alert to the possibility that their @entity1 may lack decision-making capacity. Assessment of capacity should be frequent using the appropriate legal frameworks to act in the best interest of @entity1 .
