SAN MARCOS, Calif. >> Two mornings a week, a van arrives at the Escondido home of Mario Perez and takes him to a new senior center in this northern San Diego County town, where he eats a hot lunch, plays cards and gets physical therapy to help restore the balance he lost after breaking both legs in a fall.

If he wants, he can shower, get his hair cut or have his teeth cleaned. Those twice-weekly visits are the highlights of the week for Perez, a 65-year-old retired mechanic who has diabetes and is legally blind.

“The people here are very human, very nice,” he said. “I’m gonna ask for three days a week.”

The nonprofit Gary and Mary West PACE center, which opened in September, is California’s newest addition to a system of care for frail and infirm seniors known as the Program of All-Inclusive Care for the Elderly.

The services provided by PACE, a national program primarily funded by Medicaid and Medicare, are intended to keep people 55 and older who need nursing home levels of care at home as long as possible and out of the hospital.

The program is more important than ever as baby boomers age, its proponents say.

“The rapidly growing senior population in California and across the country will put enormous strain on our current fragmented, and often inefficient, health care delivery system,” said Tim Lash, president of Gary and Mary West PACE. California officials consider PACE an integral part of the state’s strategy to upgrade care for aging residents.

The National PACE Association said data it collected for 2019 shows seniors enrolled in PACE cost states 13% less on average than the cost of caring for them through other Medicaid-funded services, including nursing homes.

Perez, like 90% of PACE enrollees nationwide, is a recipient of both Medicaid and Medicare. He’s part of a population that typically has low income and multiple chronic conditions.

PACE participants who do not receive government medical benefits can pay out of their own pockets. At Gary and Mary West, the tab ranges from $7,000 to $10,000 a month, depending on the level of care.

Nationally, 50,000 enrollees participate in PACE programs at over 260 centers in 31 states. In California, PACE serves nearly 9,000 vulnerable seniors at 47 locations.

PACE programs nationally offer all services covered by Medicare and Medicaid, and staff members include nurses, primary care doctors, social workers, dietitians, drivers and personal care attendants as well as physical, occupational and recreational therapists. PACE enrollees commonly have conditions such as vascular disease, diabetes, congestive heart failure, depression and bipolar disorder.

About two-thirds of PACE participants have some degree of cognitive impairment. The Gary and Mary West center is no exception, which is why it has alarms on all the doors. If participants become agitated, they are led to the “tranquility room,” a softly lit space with an ocean soundtrack and a recliner.

On weekdays, participants can arrive at the center as early as 8 a.m. and stay until 4:30 p.m. A PACE driver provides transportation to and from the center as well as to appointments with outside specialists.

The center opened with money donated by San Diego billionaires Gary and Mary West, telemarketing and telecommunications entrepreneurs. They’ve donated about $11 million to establish PACE centers around the country.

The center in San Marcos is spacious and cheery, with sofas and chairs scattered about and plenty of natural light. It’s meant to feel “like a friendly, inviting living room,” said Dr. Ross Colt, a retired Army colonel who joined Gary and Mary West PACE a year ago as the primary care physician on staff.

Center participants can get physical and occupational therapy in a rehabilitation gym, and the facility has a spa where they can shower or get their hair done.

The executive director, Renata Smith, recalled a woman whose husband had been bathing her with a garden hose before she joined PACE. “We’re talking about basic human dignity here,” Smith said. “The spa makes participants feel good about themselves.”

PACE programs also send personal health care aides to participants’ homes.
