About this library

A clinical outcome assessment is any standardised way of recording how a patient feels, functions or survives. This library holds 319 of them: patient reported measures such as the Oswestry Disability Index, clinician rated scales such as the Berg Balance Scale, and performance tests such as the Timed Up and Go.

Each entry describes what the instrument measures, who completes it, how it is scored and what the scores mean, and links the publication it comes from. Most entries also carry a preview of the assessment form itself, so you can see the wording of the items before you commit to using it.

The library is organised by clinical domain rather than by profession, because most instruments cross professional boundaries. The Berg Balance Scale is used by physiotherapists, occupational therapists, nurses and geriatricians alike. Browse the 20 clinical areas listed alongside these results, or search by name or abbreviation if you already know what you are looking for.

Choosing between two instruments usually comes down to three questions. Has it been validated in the population you are working with? Is the change you expect to see larger than the instrument's own measurement error? And can your patients or participants complete it without help? Every entry cites its source publication so you can answer the first two yourself.
