The residents as people first. Introduce each resident's preferences: things they like, how they like to communicate, what a successful interaction might look like, what they don't like and why, etc. This section does the most work per sentence, since most damage to residents occurs from workers treating them generically. Detail about the diagnosis helps only insofar as it changes what the worker does.
The support essentials. Each resident's support needs for the relevant shifts, medication arrangements (where permitted by the worker's role and training); the essentials of behaviour support: the strategies in plain language, early warning signs, what to do and what not to do. If a formal behaviour support plan is in place, the profile will summarise the content for the worker, and will refer to the full plan, but will not replace the training that the plan calls for.
The household's unwritten rules. The unspoken codes that keep the house functioning: about sharing space, about living in the house with visitors, about phones, about the flow of the evening. This part only your experienced staff can write, and it's the one most often missing.
The practical layer. Access, keys and codes, parking, where things are stored, equipment idiosyncrasies, emergency procedures and an escalation ladder with names and numbers that answer at the hour the shift calls.
A profile is only as good as the last update, and a stale profile is worse than no profile, since it is trusted. What works is the maintenance pattern of ownership plus rhythm: there's a named person for each house who owns it, there's a standing monthly prompt to the house team about what has changed, and when something significant happens, such as a new resident, a plan review, or an incident with lessons to be learned, the document is updated immediately. Version-date the front page so every reader knows how current their brief is.
This turns the profile from a one-off onboarding step into a living document. It's the introduction pack for bench and independent workers, it's the continuity insurance when veterans leave, it's the evidence of systematic practice when auditors ask, it's the document that lets you say yes to a 6pm coverage call, because a safe yes is only a quarter of an hour of reading away.
Imagine two houses in the same service on the same night where 3 staff are taken out by a gastro outbreak. In the first house, the cover workers arrive to a profile; they read it in the car, they greet the residents the way the profile says, they run the evening routine and the night goes like a night. In the second, there's no profile, the senior worker knows everything, and she is one of the three off sick. The covering workers improvise, the routine slips, one resident amplifies the disruption, and two incident reports come out of the night. Same service, same crisis, one document apart.
For the rest of the fortnight, choose the house which relies most greatly on one staff member, and write its profile with that person, because their next leave or resignation is your deadline.
With a current house profile, any Support Network worker is productive from the first hour, not the fifth shift.
