Study Rationale: High Expenditures?

of the former period grew about 68 percent, 26 percent and 41 percent, respectively,
while during the latter period they were about 224 percent, 43 percent and 127 percent.
Furthermore, when consider growth of expenditure compare year on year; growth rate
of the out-patient expenditure during the second period showed an upward trend and
had very rapid growth in the last two years, 2006 and 2007 (graph 2.5).
With respect to expenditure per patient, this study can merely consider the average in-
patient expenditure, because of data limitations. According to data from the electronic
payment system, the average in-patient expenditure in 2003-2006 increased over time as
shown in graph 2.6.

CSMBS Expenditure in the fiscal years 1996-2007
Out-patient In-patient Total
Ø Common assumptions of what causes increasing healthcare expenditures of CSMBS: • Overuse of NED drug?
• Overuse of brand-named drugs?
• Limited EBM practices?
• Corruption in healthcare sector?
Ø Cross-‐subsidiza,on can be a missing piece!
Study Rationale: Cross-subsidy?
Figure source: www.be2hand.com; www.imdb.com; workwithbrianandfelicia.com
Ø “Do hospitals use payments of a type of health services to subsidize or support financing of other services?”
• If so, how?, at which level?, at what degree?
Literature Review
Ø Concepts of “cross-subsidization” or “cost-shifting” from developed countries such as the U.S. (Morrisey 1994, Cutler 1998, Dranove 1988, Feldman et al. 1998, Frakt 2010 & 2011).
Ø Such theorectical concepts might not be applicable in Thailand’s healthcare systems, especially that Thai public hospitals do not have the “ability to set prices” by themselves.
Ø There was no empirical study of cross-subsidization in the contexts of Thai healthcare systems.
Study Objectives
1. To explore motivations and existing practices of the administrators of Thai public hospitals that potentially can lead to cross-subsidization (“to use payments of a type of health services to support financing of other services”).
2. To demonstrate an empirical evidence related to cross-subsidization at the hospital level, including the cost difference and the difference of excess of revenues over expenses among health schemes.
Methodology: Research Design
Ø No existing empirical studies of cross-subsidization in the contexts of Thai healthcare system.
Ø Theoretical concepts developed in countries like the U.S. might not be applicable in Thailand.
Ø Mixed-‐methods research (MMR) with the concurrent embedded research design (Creswell et al., 2009).
Source: Creswell (2009). Research design: Qualitative, quantitative, and mixed methods approaches. 3rrd ed.
Ø Primarily, the QUAL analysis.
Ø The QUAN analysis is used to compliment the QUAL analysis.
Methodology: Source of Data
Ø Data was based on three selected public hospitals: Ø Two medical centers with 1,000 and 1,134 beds
Ø One teaching hospital with 1,378 beds.
Ø Hospitals were purposefully selected, based on the accessibility to the hospital administrators and the availability of the datasets of unit cost, claims, and reimbursement.
Methodology: Data Collection
Ø Qualitative data: Ø Semi-structure interviews and focus-group interviews.
Ø 30 key informants who are responsible for the administration of the three hospitals.
Ø Verbatim was transcribed and analyzed using ATLAS.ti 7.
Ø Quantitative data: Ø Secondary data of inpatient care, collected at the patient level,
from the two medical centers.
Ø Unit-cost, charge, reimbursement, patient’s health scheme, DRG codes, and basic demographic characteristics.
Ø Analysis was conducted using Stata 12.
Qualitative Analysis
Ø Constructivist grounded theory (Chamaz, 2005; 2006) Ø Coding process (Strauss & Corbin 1990)
Ø Analyze the cost differences across health schemes Ø By using descriptive statistics and a regression analysis.
Ø Compare the differences among charge, cost, reimbursement, particularly ‘reimbursement-cost’ and ‘reimbursement-to-cost ratio’: Ø Across health schemes
Ø Across MDC groups
Ø Across Age groups
Quantitative Analysis
Ø 13 sub-themes, categorized into 4 emerging themes.
Qualitative Findings
Sub-themes Themes
Varied understanding of cross-subsidization, Unclear financing for non-healthcare missions
No mutual understanding or attitudes toward concepts and practices of cross-subsidization
Inadequate reimbursement, Non-performing loan, Unequal negotiation power
Obstacles facing management due to policies of the payers
Conflicting roles between quality & equity-focus and efficiency-focus, Limited information to manage prices and cost
Obstacles facing management due to organizational limitations
To be missions-driven organization, To focus more on efficiency than revenues, To do public funds raising, To control the volume of certain groups of patients when feasible, To advocate changes of the payer’s policies
Organizational responses to policies of the payers

Ø The average costs per visit vary across health schemes, where CSMBS patients have the highest cost.
Ø After controlling for age, gender, disease, LOS, the regression analysis confirms that the patient’s health scheme has a significant impact on the unit cost of health services.

Ø Assume that charge equals reimbursement for foreign, OOP, and ‘others’ groups.
Ø Reimbursement (or charge) is much lower than the cost for UC and foreign patients. Ø Insufficient reimbursement Ø Hospital’s burden to take care of patients without health insurance or rights (e.g. foreign patients)

Ø The hospital receives reimbursement more than the cost for only 5 MDC groups. Ø Some major diagnostic categories create a large deficit for the hospital.
MDC 5 = Diseases & disorders of the circulatory system
MDC 22 = Burns

Ø ‘Reimbursement-Cost’ is generally positive for CSMBS, and the difference is large for elder patients.
Ø This difference is negatives for almost all age groups for UC patients.
• Given our limited datasets, we found no direct evidence that suggests hospitals cost-shift by increasing prices charged to out-of-pocket payment (OPP) patients to compensate for the loss.
• Yet, patterns of decision-making of hospital administrators related to cross-subsidization were found.
• Therefore, financing policies of one health scheme also impact other patients groups within the hospitals.
What Do Findings Tell Us?
Implications for Policy and Practice
Ø To policymakers: • Demonstrates an empirical evidence of
that current healthcare financing of hospitals still inappropriate/inadequate.
• Suggests that payments from particular payers potentially can be used as a “buffer” for hospitals, potentially leading to “passive cross-subsidization” and inequity issues of healthcare access.
• Suggests the needs to “harmonize” healthcare financing in a more efficient and equitable fashion.
