YEARS LOST Years Lost due to Disability (YLD) represents the non-
DUE TO fatal health outcomes of diseases and injuries. Prevalence

DISABILITY estimates for each disease and injury, including breakdown
of the severity proportion and percentage contributing to
(YLD) its sequelae, was calculated and estimated. This prevalence,
together with a set of disability weights for each condition,
was used to calculate the YLD.

2.3.1 There was no single and comprehensive source of prevalence
Data source data for all non-fatal disease and injury. The prevalence of
for YLD diseases and injuries were drawn from a wide variety of
sources. Where possible, national data sources and local
studies were used to obtain the most reliable Malaysian
estimates.

Administrative data sources, including disease surveillance
data, diseases registries and hospitalization data, were
evaluated for their representativeness and adjusted as
necessary to estimate prevalence of certain diseases. Surveys,
epidemiological studies, and local studies were evaluated
for their representativeness and quality before being used
to estimate the prevalence. Regional and international
studies were used to produce estimates where local data
was not available or deemed unreliable. Regional studies
were preferred compared to studies and estimates from
other regions based on the assumption that this reflected
a more accurate local representation. Meta-analysis and
systematic reviews, where available, were used to obtain the
most accurate estimates in the absence of local and regional
data.

Where disease prevalence or other parameters for estimates
were not available from any reliable source, the incidence
or prevalence estimates were obtained from Global Health
Data Exchange GBD Results Tool from the Institute for Health
Metrics and Evaluation (IHME). DISMOD-II was used to
produce prevalence estimates from incidence, case fatality,
remission or duration data that was available. DISMOD-II is
a freely available software commonly used for burden of
disease analysis. The Malaysian population structure and
background mortality rates for each corresponding year is
entered into DISMOD-II to produce these estimates. Details
of the disease models and sequelae used in this study is
included in Appendix III.
