Overview of the NHI payment system and Case-Payment Initiatives

Overview of NHI payment system Unit of Payment: Fee for Services: major unit of payment Case Payment :54 cases ( until 2009) Per diem payment: chronic mental beds, day care Capitation: ventilator-dependent patients (1998-), Family Physician Initiatives(2004-),capitation Initiatives (2011-) Pay-for-performance(2001-) Global Budget: Expenditure cap: dental care(1998-), traditional medicine(2000-), clinics(2001), hospitals (outpatient ESRD) (2002-) Expenditure target: all others (home care, mental community rehab. center, payment initiatives) (2002-)

Payment system reform strategies Macro Strategies (Σ PiQi) Global budget Control cost Motivation for reform Level of payment Unit of payment Micro strategies Reform unit/level of payment (e.g. DRGs) efficiency/quality

Why DRGs? not comparable comparable It s difficult to make meaningful comparison on resources consumption among hospital patients with different levels of severity under fee-for- services (FFS). DRGs enable making meaningful comparison, thus will facilitate better hospital management by improving the effectiveness/efficiency of health care 6

Case Payment Initiatives(CPI) - First-stage stage (1995( 1995-2009) 1995-1998 :22 cases defined by procedures of DRGs without CC (FFS if with CC*) 1999: 28 new cases defined by APDRGs(ALL-Patient DRGs) Total 54 inpatient DRGs, 5 outpatient DRGs by 2009 *CC: co-morbidity and complication

Diagnosis-related Groups, DRGs Define hospital products based on patients rather than hospitals characteristics Patients with similar clinical conditions and resource use were classified into the same DRGs based on their diagnoses, procedures, age, gender, co-morbidity, complication, discharge status, etc. In 1983, DRGs were adopted by US Medicare program as basis of Prospective Payment System (DRGs-based PPS).

First-stage stage Case Payment Initiatives payment rule,1995-2009 1. Case definition: by procedures or AP-DRGs 2. Payment: lump-sum payment per admission, including physician fees. 3. Payment price set based on historical costs with appropriate adjustment 4 Outlier payment(ffs) : threshold varied by cases 5. Quality assurance : should meet minimal required services guideline 6. Readmission within 2 weeks: providers responsibility

Cost: First-stage stage CPI yielded promising results* roughly the same or slightly increase due to the payment adjustment (for under-paid surgical procedures Resource consumption significantly decreased Length of stay reduced 10% (max 40%) Cost of pharmaceutical products decrease 15% Cost of elective ancillary services decreased *Lee, YC & Yang, MC, Li, CC. Health Care Financing System in : Before and After Introduction of Case-Mix. Malaysian J. Public Health 5 (supp 2), 19-32, 2005

First-stage stage CPI yielded promising results Quality Comparable or even better than before % admissions follow guideline sig. increased ( provide standard care) Access: shifting and dumping: Code creep to FFS cases ( paid by FFS) Incentive to claim outliers (on FFS bases) Patient transfer sig reduce 40%,according to analysis of claim data. *Lee, YC & Yang, MC, Li, CC.

Development and application of DRGs and DRGs-based payment system

Why still need DRGsbased payment system under GB Global budget (GB) system do control costs yet may or may not change providers behavior, low conversion factors (of Fee Schedules) trigger providers to ask for more budgets. Incentive of FFS is against the objective of GB. The development of a national DRGs system will facilitate faster implementation of case payment system and improve the efficiency of health care provision.

Development and application of DRG (Tw-DRGs) Case definition: Tw-DRGs (modified from CMS DRG) Data: based on NHI claim data Weight: calculated based on historical claim data Weight adjustment: adjust for fee schedule change within 3 years

Development of Tw-DRGs First version :based on CMS DRGs (499 groups),2001 Second version, 2002-2004 modify DRGs structure based on local clinical practice Modify DRGs based on statistic principle Cost/LOS of at least 75% pts exceed 1 day Third version: 2005-2010 Modify DRG based on providers recommendation

Implication Grouper: DRG system is never perfect, may adopt any existing system (MS-DRG, IRDRG, ARDRGs ) as starting point and modify it according to analysis of existing data as well as local practice. Separate DRGs with payment system Application of DRGs is not limited to payment, its development should rely more on scientific research than interference of interest groups Design of DRGs-based payment system usually reflect local practice/health care system and need more political consideration.

Implication Special consideration for Payment system Outlier payment Standard threshold or case by case Variation between different levels of hospitals (negotiation) Application of new technology or devices. Phased-in strategies Gradually increase percent of cost paid by DRGs is preferred (vs. select MDCs)

Conclusions Although global budget payment system (GB) has controlled costs, it is still necessary to reform the unit of payment system (such as DRGs) to provide incentive for hospitals to improve efficiency/effectiveness (or reduce waste) Preliminary results indicate reduction on the LOS, yet readmission rate also slightly increase. DRGs-based payment system has triggered hospitals to enhance management thru establishment of clinical pathway. Quality and effectiveness of care, though lacking of evidence now, can be improved in the long-run. BNHI need to monitor the quality of care and modify payment to reflect the use of new technology Bundle-payment may be necessary in the long-run.
