Abstract

In the face of increasing financial pressure on our health care system, one way to reduce costs while maintaining or even improving outcome quality is to improve work flow efficiency. Network Planning Technique (NPT) is a tool for mapping and analyzing work flows. Designing a network plan requires four steps. Step 1 is concerned with the determination of the work flow structure. Step 2 deals with data acquisition. Based on the data retrieved a network plan is created in Step 3. Step 4 includes the calculation of the critical path and slack times under optimistic, realistic and pessimistic conditions. Applied to the ultrasound division in our department a total examination time of 34:14 minutes was calculated with 23:09 minutes total slack time for the technician under realistic conditions. Using NPT creates transparency in work flows and allows us to estimate resource demands. A comparison between two different divisions with a similar work flow structure but different resource allocation demonstrates this method's potential for improving work flows. Limitations of the NPT can be noted when considering cycle overlap in repetitive work flows and modeling non-regular activities.

Medicare program; changes to the hospital inpatient prospective payment systems and fiscal year 2004 rates. Final rule.

We are revising the Medicare hospital inpatient prospective payment systems (IPPS) for operating and capital costs to implement changes arising from our continuing experience with these systems. In addition, in the Addendum to this final rule, we are describing changes to the amounts and factors used to determine the rates for Medicare hospital inpatient services for operating costs and capital-related costs. These changes are applicable to discharges occurring on or after October 1, 2003. We also are setting forth rate-of-increase limits as well as policy changes for hospitals and hospital units excluded from the IPPS that are paid on a cost basis subject to these limits. Among other changes that we are making are: changes to the classification of cases to the diagnosis-related groups (DRGS); changes to the long-term care (LTC)-DRGs and relative weights; the introduction of updated wage data used to compute the wage index; the approval of new technologies for add-on payments; changes to the policies governing postacute care transfers; payments to hospitals for the direct and indirect costs of graduate medical education; pass-through payments for nursing and allied health education programs; determination of hospital beds and patient days for payment adjustment purposes; and payments to critical access hospitals (CAHs).

Medicare program; changes to the inpatient rehabilitation facility prospective payment system and fiscal year 2004 rates. Final rule.

In this final rule, we are establishing the prospective payment rates for inpatient hospital services furnished under Medicare by inpatient rehabilitation facilities (IRFs) for Federal fiscal year (FY) 2004, as required under section 1886(j)(3)(C) of the Social Security Act (the Act). As required by law and regulations, we are specifying the classification and weighting factors for the IRF case- mix groups and providing a description of the methodology and data used in computing the prospective payment rates for FY 2004. These rates are applicable to discharges occurring on or after October 1, 2003 and before October 1, 2004. In addition, we are revising and clarifying policies governing the payment for inpatient hospital services furnished by IRFs under the IRF PPS.

Medicare program; prospective payment system for long-term care hospitals: annual payment rate updates and policy changes. Final rule.

This final rule establishes the annual update of the payment rates for the Medicare prospective payment system (PPS) for inpatient hospital services provided by long-term care hospitals (LTCHs). It also changes the annual period for which the rates are effective. The rates will be effective from July 1 to June 30 instead of from October 1 through September 30, establishing a "long-term care hospital rate year" (LTCH PPS rate year). We also change the publication schedule for these updates to allow for an effective date of July 1. The payment amounts and factors used to determine the updated Federal rates that are described in this final rule have been determined based on this revised LTCH PPS rate year. The annual update of the long-term care diagnosis-related groups (LTC-DRG) classifications and relative weights remains linked to the annual adjustments of the acute care hospital inpatient diagnosis-related group system, and will continue to be effective each October 1. The outlier threshold for July 1, 2003, through June 30, 2004, is also derived from the LTCH PPS rate year calculations. In addition, we are making an adjustment to the short-stay outlier policy for certain LTCHs and a policy change eliminating bed-number restrictions for pre-1997 LTCHs that have established satellite facilities and elect to be paid 100 percent of the Federal rate or when the LTCH is fully phased-in to 100 percent of the Federal prospective rate after the transition period.
