| description |
With the increasing burden of metabolic syndrome, the prevalence of coronary artery
disease (CAD) is rising in Malaysia. Percutaneous coronary intervention (PCI) is a
common treatment modality for CAD. Cost of PCI and other cardiac procedures are
escalating with the advancement in medical technology. Scarcity of local cost evidence
impedes the planning for sustainable cardiology service. Cost analysis is vital for
healthcare resource allocation. Limitations in the quality and availability of patient and
financial data from low- and middle-income countries (LMIC) often constrain the
implementation of cost analysis. This research aimed to estimate the cost of PCI in
Malaysia via a modified costing method. By evaluating the cost variation between
cardiac centres, we outlined the cost-saving strategies for cardiology service in
Malaysia. This cost analysis was conducted from the perspective of healthcare providers
at 5 cardiac centres from January to June 2014. Clinical data was extracted from a
national cardiac registry. Cost data collection was conducted using mixed method of
top-down and bottom-up approaches. The primary outcome of interest was the cost of
PCI hospitalization. Using a clinical event pathway, cost items under each unit of
analysis are identified, valuated and calculated to produce unit cost estimates. Unit costs
of interest were costs of hospital general overheads, cardiac ward admission, cardiac
catheterization laboratory utilization and PCI consumable; which made up total
hospitalization cost. Average cost by centre were derived with top-down approach and
compared between centre. Individual-level costs were generated via mixed method to
enable patient-level comparison and determination of cost predictors. Analyses included
descriptive statistics, logistic regression to determine the predictors of long
hospitalization and linear regression to predict increased hospitalization cost. The
average total hospitalization cost for an elective PCI patient ranged from RM 11,519 to
RM 14,356 at the 5 centres. The dominant cost driver was PCI consumable. Day-care
iv
facility resulted in 80.5% cost reduction. With a sample of 2260 patients, individual
patient-level mean hospitalization cost showed a wide distribution of RM 16,999 +
7,337. Regression analysis showed number of stents as a strong cost predictor. Patients
with acute coronary syndrome, presence of bifurcated lesion, involvement of left main
stem artery and failed revascularization during PCI were also expected to incur higher
hospitalization cost. Using the findings from this study, similar cost studies can be
conducted for other healthcare services. The modified costing methods will be useful
for like-minded researchers in LMIC who intend to conduct health economic evaluation
in the setting of limited data availability. In conclusion, the PCI cost burden on
Malaysian public cardiac centres was considerably high. PCI consumable especially

practice such as collaborative purchasing arrangement may deliver cost reduction.
Establishment of day-care facility is another viable cost-saving strategy. The study
recommendations will be vital for policy makers during decision-making on resource
