Most of the cost of getting care to a home in west St. Louis County is not on any invoice. It is in the gas, the time, the tolls and parking, and the hours someone spends in a waiting room or a line at the counter. Those costs repeat, which is why they add up. Start by writing them down.

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.

Count one week of trips

For one week, list every trip: the trips to the hospice office, the pharmacy, medical appointments, the grocery, and any errand a hired helper runs if they drive. Note where each trip started, where it stopped, the miles, and the minutes. Use your own calendar and your own odometer, not an average you found somewhere else. If a hired helper picks up a prescription as an errand, put that on the list too, and keep the medicine routine with the family.

What makes a trip expensive

Distance is the first driver, but it is not the only one. Each separate stop repeats the drive out and back, so three short trips can cost more than one longer one. Waiting rooms and pharmacy lines add time that nobody charges for and everybody pays. Tolls and parking add to the figure, and so does the wear on a car that is driven every day.

What to ask before the trips repeat

Ask the pharmacy whether it delivers, and what the fee is if it does. Ask the grocer the same. Ask the clinic whether a visit can be booked on the same day as another appointment you already have. Ask the hospice whether a visit time can be moved to a day you are already out. If you hire a helper, ask whether errands are billed by the hour or by the trip, and whether driving time and mileage are included in the rate.

Keep the log in one place

Keep the log where everyone who drives can write in it. If you plan to claim any of these trips on your taxes, ask a tax preparer what records they accept, and check the current instructions for the year you file. Rules change, so do not rely on a number you read earlier. The log is still useful even if nothing is claimed, because it shows you which trip is worth combining first.
