What should you ask when touring The Residence at Watertown Square?

Ask The Residence at Watertown Square for its latest compliance review outcome first, then cover overnight staffing, the full fee schedule, and which care needs would force a move.

• Can we visit at mealtime and in the evening without an appointment?
• Do you accept MassHealth Group Adult Foster Care (GAFC) or Senior Care Options (SCO) for care services?
• How do you handle a hospital discharge back to the residence?
• What is the full monthly fee for my parent's care level, and what triggers an increase?
• Which care needs would require a move to a nursing home?
• How long have the executive director and resident care director been in their roles?
• Is a nurse on site every day, and who covers nights and weekends?
• What happens if a resident runs out of private funds?

Visit twice — once at a meal — and read the residency agreement before paying a deposit. Massachusetts gives ALR residents specific resident rights, and the Long-Term Care Ombudsman Program can help if problems come up later.

How does moving into The Residence at Watertown Square work?

Before anyone moves into The Residence at Watertown Square, Massachusetts rules require the residence to screen and assess the prospective resident and agree a written service plan with the family.

• Residency agreement and disclosures. The residence must give you its residency agreement and a disclosure of fees, services and discharge terms; take them home and compare them before paying a deposit.
• Special Care Residence admission. Admission to The Residence at Watertown Square's 25-unit Special Care Residence is based on a dementia diagnosis and an assessment that the secured setting is appropriate; ask what criteria would move a resident between its traditional and Special Care units.
• Medication plan. Decide whether your parent will self-administer, receive Self-Administered Medication Management (SAMM) help from aides, or need Limited Medication Administration (LMA) by a nurse — it affects both care and fees.
• Payment. Rent and care are almost always private pay in an ALR; long-term care insurance and VA Aid & Attendance can offset them.

Most moves take two to four weeks once a unit is available; a hospital discharge can compress that to days, which is when a second set of eyes on the agreement helps most.
