Household Catastrophic Health Expenditure From Oral Potentially Malignant Disorders And Oral Cancer In Public Healthcare Of Malaysia
1. Household Catastrophic Health Expenditure
amongst OPMD and Oral Cancer Patients
in Public Healthcare of Malaysia
Sivaraj Raman
2. BACKGROUND
● Oral cancer and Oral Potentially Malignant Disorders (OPMD)
causes significant disease burden and financial distress1
● Catastrophic healthcare expenditures (CHE) from unforeseen
payments, debilitating disease and treatment traps
households in economic crises2
● ASEAN Costs In Oncology (ACTION) initiative reported 48% of
the households with cancer patients experienced CHE3

3. SIGNIFICANCE
● While Malaysian public healthcare is
highly subsidized, Out-Of-Pocket (OOP)
expenditure for treatment is expected to
be multifold higher1
● Prevalent among the underprivileged,
female and indigenous communities2,3
● More than 70% of cases are still
diagnosed at later stages2

5. MATERIALS & METHODS
3. Cost Estimation Simulation Model
1. Prospective Patient Survey
2. Retrospective Record Abstraction
• Sociodemographic data, income,
healthcare OOP expenditures
• Healthcare utilization,
hospitalization and visit details
• To generate hospital fees,
travel and transport cost
Healthcare
OOP expenditure* X 100%
Household income
CHE = 10%*
* ALL cost estimated for the first 1 year after diagnosis
● Association of sociodemographic factors with CHE was
analyzed via multivariate binary logistic regression
● Patients with oral cancer and OPMD were recruited from oral maxillofacial specialist clinics in
Hospital Tengku Ampuan Rahimah and Hospital Umum Sarawak.

a Sociodemographic variables were explored in univariate binary logistic regression by holding diagnosis
(OPMD or oral cancer) constant
b Multivariate binary logistic regression indicated that there was a significant collective effect between age
group, race, income group, education, and diagnosis with CHE, χ2(7) = 68.95, p< 0.001
12. DISCUSSION:
● Pattern of larger OOP share for travelling consistent in
countries with universal health coverage 1
● Larger travel cost in late stage cancer was contributed
by frequent visits for multidisciplinary care and longer
distance travelled by patients in rural areas
[MYR 896 (urban) vs MYR 1,870 (rural)]
● Traveling cost to access health services can become a
barrier, even if treatments are subsidized 2

13. DISCUSSION:
● Indian ethnicity was not associated with late-stage
diagnosis and lower income. It may be interlinked with
CHE through other socio-economic factors
● B40 households spent larger percentages of their
income on healthcare than M40/T20 groups1
● However, OOP expenditures were similar across income
groups due to high subsidization and cost capping.
Thus, income was the determinant of CHE2

14. DISCUSSION:
● Despite the high subsidization, oral cancer in
Malaysia echoed similar financial burden with
other ASEAN countries 1,2
● Fixed-subsidization policies may not
necessarily cater to the poorer community
● PeKa B40 to incentivise patients is timely, but
none of the current respondents benefitted
from the initiative3

15. CONCLUSION:
CLINICIANS
Current provision of subsidies
and financial supports may
still be inadequate and
inaccessible to shield the
more vulnerable group from
