The invoice said 4.2 kg a month. The store cupboard said 1.9 kg. Two tubs of gel powder had been signed for in April and one was still sealed in June. Somewhere between the delivery note and the 3 a.m. round, half the expected doses were not happening, and no incident report had been raised because nothing had gone visibly wrong. The bin smelled, the night staff said the powder made no difference, and the manager assumed the product was weak.
This article sets out how to audit gel dosing on a night shift without turning it into a disciplinary exercise, what the numbers usually reveal, and the four changes that closed a 45 per cent dosing gap in a 60-bed home over eleven weeks.
Observation changes behaviour for a week and then stops. Consumption is harder to fake. Weigh the tub at the start and end of each week on a kitchen scale accurate to 5 g, divide by seven, and divide again by the number of collections recorded in the urine output chart. The result is grams per collection, which you can compare directly with the dose card.
In the home above, the baseline was 11 g per collection against a card figure of 5 g for an average 400 ml. That looked like over-dosing until the number of recorded collections was checked: 214 per week against a nightly average of 41 bedpans and bottles, which is 287. Roughly a quarter of collections were not being recorded, and the ones that were recorded got an inconsistent dose, some 20 g, some nothing at all.
The 3 a.m. round is the one with the least supervision and the most time pressure. In this home, three things conspired. The scoop lived in a locked treatment room, and the night nurse carried one key for the drug trolley, the laundry and the treatment room. The sluice light was on a motion sensor with a 90-second timer, so anyone standing at the sink for a full dose stood in the dark. And the powder tub was a 25 kg sack on the floor, which required two hands, a scoop and a clean dry surface that did not exist at that hour.
None of those is a motivation problem. Each is a design problem, and each has a cheap fix: a 2 kg tub with a hinged lid on the trolley, a battery light clipped above the sink, and pre-portioned sachets that open with one hand.
Put a tally sheet on the trolley for one week. Every collection gets a tick, and every sachet goes in a waste bag that is counted at handover. Compare three numbers: collections, sachets used, and litres in the waste containers. If sachets used is less than collections, dosing is being skipped. If litres collected exceeds the sum of recorded volumes by more than 15 per cent, the recording is the weak point rather than the dosing.
Do the same measurement on a day shift in the same week. In most homes the day figure will be 90 per cent or better, which is useful, because it shows the night gap is about the round and not about the people on it.
First, move the powder to the trolley. A sealed 2 kg tub with a scoop clipped inside the lid removes the key, the walk and the two-handed lift.
Second, replace the scoop with sachets for the night round only. Cost per dose rises by about 3 pence, and the dose becomes repeatable by a tired person at 3 a.m.
Third, add a single line to the handover sheet: gel doses given, sachets remaining. It takes ten seconds and makes the number visible without asking anyone to justify themselves.
Fourth, re-weigh at week three, six and eleven. The gap closed from 45 per cent to 9 per cent by week eleven, and consumption rose from 1.9 kg to 3.6 kg a month, which is still below the original invoice and now matches the work actually being done.
A dosing audit is not a cost-cutting tool. In this case the trust spent more on powder after the audit than before, and saved it several times over on bin liners, linen replacements and one carpet. Report the grams per collection alongside the leak incidents and the odour complaints; three numbers on one page will carry more weight with a finance director than any product brochure.
If your audit shows consumption below the theoretical figure and the product is being blamed, it is worth ruling out the powder before rewriting the procedure. A retained sample tested for absorption in saline will settle that in a day, and the reference figures for our standard and high-absorbency grades are published at the SAP powder product pages.
