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

### DEVICE (one letter): the product the report is about (text first, then the brand in the header)
- C: BEDSIDE OR 3-IN-1 COMMODE: a stationary frame with a seat and a bucket or pail, used by the bed or over the toilet (drop-arm and bariatric commodes included).

- B: BATH OR SHOWER SEAT, BENCH OR TRANSFER BENCH (not used over a toilet).
- O: another device (walker, wheelchair, bed, lift, anything else).
- 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.
- L: LEG OR HEIGHT ADJUSTMENT: a leg collapsed, telescoped, slid in, buckled or bent; a push-button or pin did not lock; a leg extension or foot came off.
- A: ATTACHMENT: a seat, raised seat, clamp, bracket, frame or rail came off or shifted on the toilet, came apart from the frame, or was not secured.
- K: BREAK: a frame, weld, seat, backrest, arm or bracket broke, cracked or snapped.
- G: ARM, RAIL OR BACK GAVE WAY: an armrest, drop arm or rail moved, folded, swung or released unexpectedly without breaking.
- W: WHEEL, CASTER OR BRAKE: a caster broke or came off, a brake or caster lock failed, the chair rolled.
- P: BUCKET, PAN, SPLASH GUARD OR LID: leaked, broke, fell or cut.
- S: SKIN OR BODY CONTACT: a pinch, cut, scrape, pressure injury or burn from the device with no failure above.
- F: FALL OR TIP WITHOUT A FAULT: the user fell or the device tipped and no part is said to have failed.
- Q: a device problem is alleged but no part 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, stitches, hospital, death; pain alone counts). y when the event type is Death.
- fall: the user fell or went to the ground.
- user: the report says the user or a third party caused it (misuse, wrong assembly or installation, weight over the limit, a modification, a missing part not fitted), 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.
