QuickDASH score calculator

Eleven questions, one per concept

The QuickDASH is not a random third of the long form. Beaton and the Upper Extremity Collaborative Group built three candidate 11-item scales from field-test data on 407 patients — one by concept retention, one by item-total correlation, one by Rasch modelling — and tested them in a 200-patient longitudinal cohort. The concept-retention version tracked the full instrument most closely and became the QuickDASH. That is why the items read like a tour of daily life: a jar, chores, a bag, washing, a knife, forceful recreation, social life, work, pain, tingling and sleep.

Each answer is a number from 1 (no problem) to 5 (the worst the item allows). Six items rate difficulty; the others rate interference, limitation, symptom severity and lost sleep. The score is the mean of what was answered, shifted and stretched onto a 0–100 ruler.

Scoring the example by hand

The blank is not scored as zero, and not as the patient’s average: it simply drops out of the divisor. That is what the IWH formula, (sum of n responses ÷ n − 1) × 25, does.

The two optional modules

The core eleven stop at everyday function. A violinist, a roofer or a club tennis player can score near the floor and still be unable to do the one thing they came in about. For them IWH adds a work module and a sports / performing arts module, each of 4 items on the same 1–5 scale: technique, pain, performing as well as they would like, and time spent.

• Each module gets its own 0–100 score by the same formula. It is never added to, or averaged with, the core score.
• A module tolerates no blanks: all four answered or no module score.
• Offer a module at the evaluation only when the patient’s goal lives there, then keep it at every re-check. A module that appears at week six has no baseline to compare with.

When the module is the goal, write it into the plan of care as its own outcome line, next to the core score, so the payer sees why therapy continues after the daily-life number has settled.

Reading a change: two yardsticks

The single number matters less than its movement between the evaluation and the re-examination. Two published figures frame that movement, and they disagree on purpose — one answers “would the patient notice?”, the other “could this be noise?”.

Because the MCID sits below the MDC95, IWH suggests treating the MDC95 as the interim threshold for a single patient. The calculator reads your change against both: past 8 but short of 16 is “probably better, not yet proven”. That band is exactly where the default example lands.

A nine-point drop can be a real recovery or a good day at the desk. One form cannot tell you which; the next one usually can.

A 2013 systematic review by Kennedy and colleagues found strong evidence for the QuickDASH’s reliability and validity, but strong negative evidence on responsiveness, because its change scores correlated less well with patients’ own global ratings of change. Pair it with a numeric pain rating and a measured range, logged on a range of motion chart, rather than letting it carry the re-evaluation alone.

Why there are no severity bands here

Some score sheets print “mild”, “moderate” or “severe” under the number. The instrument’s developer does not: the IWH FAQ states that there are, at present, no such divisions for the DASH or the QuickDASH. It also warns that the scores are points on a ruler — a DASH of 65 is not 65 per cent disability — and the short form reads the same way.

What IWH does publish are the mean scores of known groups from its validation data, which the bar under the readout marks as reference ticks:

QuickDASH or the full DASH?

IWH rates both forms valid, reliable and responsive, and says the long form’s extra precision may make it the better choice for following one patient. The numbers behind that advice are close, though, and the short form takes about 5 minutes to complete and 2 to score.

• Pick the QuickDASH for a busy outpatient caseload, for a patient who stalls on long forms, or when the visit already carries a pain rating, a neck disability index or other paperwork.
• Pick the full form with the DASH score calculator when one patient’s trajectory is the whole point — a surgical case, a disputed work claim, a slow plateau you need to see clearly.
• For the leg, the equivalent short self-report is the LEFS, which runs the other way: higher is better.

Giving the form well

• Ability, not habit. If the patient has not done a task this week, IWH asks them to rate how hard it would have been. “I didn’t, because I couldn’t” is a 5.
• Either arm. The items are not tied to the affected side; a patient who opens the jar with the good hand rates that.
• Adults, on paper. IWH gives 18–65 as a general guideline and does not endorse reading it out over the telephone.
• Same schedule every time. IWH’s minimum for the DASH family is the evaluation and discharge; add the re-examination your documentation routine already sets.

Paste the copied line into the objective section of your SOAP note; it carries the score, the items answered, any module and the change verdict. Put the shoulder and elbow ranges beside it, read against the upper-extremity norms, so the function score and the impairment travel together.
