ACO AND NON-ACO AFFILIATED HOSPITALS DISCHARGE PATTERN TO SNFS BASED ON SNFS STAR RATING

Hospitals Collaborate with SNFs,Home Care, Hospice, to Reduce Readmissions

_ These penalties are due to the Hospital Readmissions Reduction Program, part of the Affordable Care Act. They are based on high readmission rates for patients discharged for three conditions: chronic heart failure, heart attack, and pneumonia. (These readmissions may or may not be related to the previous hospitalization.) Data on each hospital’s readmission rate will soon be posted on CMS’s H...

Optimal Parameterization of SNFS

The Special Number Field Sieve factoring algorithm has a large number of parametric choices, each of which can affect its run time. We give guidelines for these choices along with a discussion of useful coding optimizations. We also give a theoretical argument which shows that the choice of sieving region that has been used so far in successful factorizations is not optimal. §

ACO-Affiliated Hospitals Reduced Rehospitalizations From Skilled Nursing Facilities Faster Than Other Hospitals.

Medicare's more than 420 accountable care organizations (ACOs) provide care for a considerable percentage of the elderly in the United States. One goal of ACOs is to improve care coordination and thereby decrease rates of rehospitalization. We examined whether ACO-affiliated hospitals were more effective than other hospitals in reducing rehospitalizations from skilled nursing facilities. We fou...

A Kilobit Hidden SNFS Discrete Logarithm Computation

We perform a special number field sieve discrete logarithm computation in a 1024-bit prime field. To our knowledge, this is the first kilobit-sized discrete logarithm computation ever reported for prime fields. This computation took a little over two months of calendar time on an academic cluster using the open-source CADO-NFS software. Our chosen prime p looks random, and p−1 has a 160-bit pri...
