## Pool

## What you record for each report
One line per report: `report_key,device,problem,injury,fall,standing,user,finding,note`

### DEVICE (one letter): what the report is about (text first, then the brand in the header)
- W: a STANDING WHEELCHAIR: a manual or power wheelchair that can raise the user to standing (Permobil Corpus VS, LifeStand, Levo, Redman, Superstand and similar).
- F: a STANDER OR STANDING FRAME: a frame that holds a person upright and does not move them around as a wheelchair (EasyStand, prone, supine or sit-to-stand stander, mobile stander, standing frame used at home, school or therapy).
- O: another device (a patient lift, including a sit-to-stand lift; an ordinary wheelchair; anything else); a stander or standing wheelchair is only mentioned.
- N: no event.

### PROBLEM (one letter): what the report says went wrong FIRST (code the allegation even if the maker found no fault). If several apply, use the first in this list.
- P: PINCHED, CAUGHT OR TRAPPED: a body part caught, pinched or crushed by the moving mechanism, a strap or the frame.
- M: STAND MECHANISM: the stand or lift mechanism, actuator, gas spring, pump, lever or lock failed; would not raise or lower; moved by itself, too fast or unevenly; stuck standing or part way.
- K: SUPPORTS AND STRAPS: knee block or knee pad, chest or trunk pad, hip pad, foot plate or foot strap, belt or harness broke, slipped, loosened or released.
- S: STRUCTURE: frame, weld, bracket, bolt, tray, back or seat broke, cracked, bent or came loose.
- E: ELECTRICAL OR CONTROLS: joystick, controller, switch, battery, charger, wiring, error code; smoke, fire, sparks or melting.
- D: DRIVING, WHEELS OR BRAKES: the chair drove, veered or did not stop as expected; wheel, caster, tire, brake or drive motor problem.
- T: FALL OR TIP WITHOUT A FAULT: the user fell or the device tipped and no part is said to have failed.
- U: BODY EVENT WITHOUT A FAULT that is not a fall: a fracture, skin or pressure injury, fainting or blood-pressure drop, pain or swelling from standing, with no part said to have failed.
- Q: a device problem is alleged but no part or behaviour is named.
- X: an event is described but nothing failed and nothing above fits.
- N: no event.

### FLAGS (y or n)
- injury: harm to the body or medical care is stated (bruise, cut, fracture, burn, stitches, hospital, death; pain alone counts). y when the event type is Death.
- fall: the user fell, went to the ground or the device tipped over with the user.
- standing: the event happened while the user was standing, being raised or being lowered (or the stand function was in use).
- user: the report says the user or a third party caused it (misuse, wrong setup or adjustment, straps not fastened, a modification, use against the instructions), as the cause or the maker's conclusion.

### FINDING (one letter): what the maker found
- D: a fault was found or confirmed, or a part was replaced because it was faulty.
- N: no fault found, worked as designed, or the cause was outside the device.
- X: not evaluated, not returned, or nothing stated.

### note
At most 15 words: device, problem, what made it hard. No quotes longer than 6 words. No personal details.
