(CNN) Frail older adults are finding it harder than ever to get paid help amid acute staff shortages at home health agencies.

Several trends are fueling the shortages: Hospitals and other employers are hiring away home health workers with better pay and benefits. Many aides have fallen ill or been exposed to Covid-19 during the recent surge of omicron cases and must quarantine for a time. And staffers are burned out after working during the pandemic in difficult, anxiety-provoking circumstances.

The implications for older adults are dire. Some seniors who are ready for discharge are waiting in hospitals or rehabilitation centers for several days before home care services can be arranged. Some are returning home with less help than would be optimal. Some are experiencing cutbacks in services. And some simply can't find care.

Janine Hunt-Jackson, 68, of Lockport, New York, falls into this last category. She has post-polio syndrome, which causes severe fatigue, muscle weakness and, often, cognitive difficulties. Through New York's Medicaid program, she's authorized to receive 35 hours of care each week. But when an aide left in June, Hunt-Jackson contacted agencies, asked friends for referrals, and posted job notices on social media, with little response.

"A couple of people showed up and then disappeared. One man was more than willing to work, but he didn't have transportation. I couldn't find anybody reliable," she said. Desperate, Hunt-Jackson arranged for her 24-year-old grandson, who has autism and oppositional defiant disorder, to move into her double-wide trailer and serve as her caregiver.
