The right amount of care is not a number you should guess from a website. For a parent in Oro Valley, a better starting point is to map the times of day when routines are working, the moments when something is repeatedly missed, and how much unpaid family help is already holding the week together.
Map the week by daypart, not by a guessed number of hours.
Getting up, bathing, dressing, breakfast, medication organization?
Meals, appointments, errands, mobility, companionship?
Dinner, routines, confusion, fatigue, family availability?
Waking, toileting, wandering, falls, caregiver exhaustion?
Map the day before you count hours
Walk through a normal morning, afternoon, evening and night. Note what the older adult does independently, what requires reminders, what family currently handles, and what becomes unsafe or unreliable when no one is present. Patterns are more useful than a general statement that a parent needs more help.
What matters locally
Consolidated page evidence. NIA functional framework, PCOA resources, Dial-a-Ride, Oro Valley Hospital and local community programs support a needs-by-time-of-day worksheet; company minimums/dayparts unapproved.
Pima County aging-services backbone. Pima Council on Aging is the Area Agency on Aging for Pima County and helps older adults and caregivers navigate transportation, caregiver support, meals, in-home help and other aging resources.
Oro Valley Dial-a-Ride. Sun Shuttle's Oro Valley Dial-a-Ride provides local demand-response transportation under eligibility, reservation, fare and service-boundary rules that families must verify directly.
Local hospital anchor. Oro Valley Hospital is a Northwest Healthcare hospital serving the Oro Valley area with emergency, inpatient and rehabilitation-related services.

Separate occasional help from recurring gaps
One difficult grocery trip is different from missed meals every afternoon. A single ride to an appointment is different from a parent who can no longer drive safely. Recurring gaps are usually the best place to begin because they show where a dependable schedule may reduce the most stress.
Count the family care that is already happening
Families often underestimate current care because it is spread across phone calls, errands, meal preparation, medication organization, transportation and check ins. Put that time on paper. It shows whether the present arrangement is sustainable or simply being held together by one exhausted person.
Match needs to the right kind of support
Non medical home care, skilled home health, therapy, transportation programs, adult day services and residential care solve different problems. The goal is not to maximize paid hours. It is to put the right kind of support around the needs that are actually occurring.
Reassess when the pattern changes
Care needs are not fixed. A fall, hospital stay, new diagnosis, caregiver burnout or change in driving can alter the week quickly. Revisit the plan when the family starts adding emergency coverage or when one person is carrying more responsibility than they can sustain.
Local resources to keep on the list
Arizona ALTCS / HCBS boundary. AHCCCS ALTCS materials distinguish attendant care, personal care, homemaker, home health and other long-term-care categories for eligible members; these public-program categories are not a private provider's task list.
Dementia and caregiver support. PCOA provides caregiver and memory-related support resources for Pima County families, including dementia-oriented education and caregiver navigation.
