Trends in Medicare home health care use: 1997-2001.

The Balanced Budget Act of 1997 mandated a major overhaul in Medicare payment for home health care with an interim payment system (IPS) preceding a prospective payment system (PPS). This study extends an earlier analysis of the impact of the IPS to determine whether home health use and spendingtrends changed after the introduction of the PPS. The rapid decline in the incidence of use and visits per user under the IPS slowed in its final year and then picked up again in the first year of the PPS. In addition, average payment per visit increased sharply under the PPS. Little is known about the impact of continued large reductions in home health services since 1999.
