This guide is for a family arranging help for an older adult who lives alone in a home in St. Charles County or west St. Louis County. The adult still manages most of the day but wants steady help at the points where the routine breaks down. The goal is not to cover every hour. It is to match visits to the windows the adult already keeps.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

Start with a plain day on paper. Write down the times the adult usually wakes, eats each meal, goes outside, rests, and goes to sleep. Mark the stretches when the adult is alone, the times a neighbor or relative calls or drops by, and the hours when the house is quiet at night. Use the adult's real routine, not a tidy schedule that looks good on a form.

Next, mark who covers each window now. A window may be covered by the adult alone, a family member, a neighbor, or no one. Only the windows with no one covering them, or with a task the adult can no longer finish comfortably, become candidate visit windows. Keep each of those windows at the same clock time every day so the adult knows when to expect the caregiver.

Give each window a short task list in writing before the first shift. A morning window might cover a breakfast set-out, a kitchen reset, and a check that the front door is locked. A late afternoon window might cover a meal set-out, bringing in the mail, and moving bins to the curb on pickup day. A bedtime window might cover a check of lights and doors and making sure the phone is within reach. Keep each list to what the family and the adult have agreed on. Health questions go to the family's doctor.

Checklist before you talk to any agency: a one-page list of the fixed windows, the clock time for each, the task list for each, the person or people who cover each window now, and which window would be the first to move if plans change. A page that stays unedited can go to an agency and to a neighbor alike.

Questions to ask each agency about the fixed windows. Can the same clock time be held every day, and what happens when a scheduled caregiver is sick or late? Does the agency send the same caregiver to the same window, or does the window rotate? What is the shortest visit it will schedule, and does that shortest visit still fit the task list? How does the office handle a request to move a window, and does it confirm the change in writing? Who tells the family first when a window cannot be covered?

Compare the answers against the written plan, not against each other's brochures. An agency that can hold one window with the same person every day can serve the adult better than an agency that describes many hours spread loosely across the week.

Test the plan against a normal week, not a holiday week. Drive the route to the home at the clock time of each window. Note whether a window falls during school pickup or rush-hour traffic on the main roads. If the family lives across a county line, check the drive from the agency's office to the home at the time each window starts.

Use public help that already exists. The county senior services office and the area agency on aging can explain what local support is available to older adults who live alone. A public library's information desk can point to listings for senior services and caregiver groups. Use these to fill windows no agency will cover and to build a backup for the days a window falls through.

To check whether enough home care businesses operate near the home, the desk's guide How to read a caregiver-supply map for your county explains the figures and what they do not show.

Close the plan by naming one family member who checks it at the same point each month and who receives the call whenever a window moves. A plan with a named keeper holds up far better than one that lives only in the adult's head or in a phone note nobody opens.
