Even after plans to reduce staff and close units, Miami-based Jackson Health System is getting close to its bare minimum for cash-on-hand. As of Oct. 31, Miami-Dade's public hospital system had 20.8 days of cash to pay its bills, including payroll. Even accounting for planned cost-cutting measures, Jackson estimates it will have 16.5 days of cash in May and will drop dangerously low to 2.4 days of cash in August 2010, the Miami Herald reports.
