METHODS
Introduction
The NMDS is designed, broadly speaking, to estimate the quantity and pattern of use of medical devices in Malaysia, as well as to estimate our expenditure on devices. This is an ambitious project,
which requires multiple surveys targeting the various levels of the medical device supply chain and utilization in healthcare facilities in the country in order to capture all the required data to meet its
purpose. For this irst effort, we had therefore realistically targeted data sources that are absolutely critical and accessible.
Hence, the statistics on the availability of medical device in this report are estimated based on data from only a limited number of surveys. In particular, the scope of the survey was limited to:
• Hospitals only, though for certain therapy areas Nephrology, Cardiology, we were able to
supplement the data from more specialized surveys conducted by the National Renal Registry NRR and National Cardiovascular Disease Database NCVD
• Asset device only. Data on disposable devices will have to await future survey.
Survey Population, Sampling And Response Coverage Rate
The survey conducted by NMDS and supplemented by those by NRR and NCVD, its survey population, its sampling unit and sample size, and the survey response or coverage rates are summarized in the
table below.

Private sector 79

Note: 1. Public sector consists
of 132 MOH, 3 University and 2 Armed Forces hospitals. 2. Response rates vary between specialties.
The survey conducted by NMDS and supplemental surveys by NRR and NCVD were entirely by primary data collection. For MOH data, available database on device asset was also used to cross-
check the data.
Data Management
The collected data, whether in databases, on paper or electronic data collection form, is compiled into a single database, appropriately processed and coded prior to statistical analysis.
The database server is running on a Windows 2000 Server. The server environment is Intel Xeon 2.4 Mhz, with a total of 2GB RAM memory and 67.8GP Raid5 Hard disk. The NMDS database was
created in Ms SQL Server 2000. The application has 3 modules: Contact Management, Data Entry and Data Processing.
xviii
The data processing steps for this initial version of NMDS data are presented as follows, in 2 phases:
Phase 1 SurveyDatabase Development and Data Collection
1. On the basis of the NMDS project’s Terms of Reference ToR, some initial discussions were
held within CRC, supplemented with research on literature to develop the irst drafts of NMDS survey forms.
2. Various existing databases were obtained and studied to extract learnings for application on the
NMDS. Where relevant, these learnings were used to enhanceedit the structure and content of survey forms.
3. On the basis of the said information in 1 2, the irst draft of the survey forms were produced
and presented for challenge of adequacy in the required data ields variables for each specialty. 4.
Draft survey forms were shared with internal and external referees and the feedback was collated for the inalization of the survey forms.
In most cases, the project team had to consult with the experts in various disciplines to get a better understanding of the variables of signiicance.
5. The survey forms were then inalized for approval, with the inal versions being made up of 28
medical specialties and 5 supportive specialties.
The variables required were divided into 3 sections: Section 1: Establishment Details.
Section 2: Diagnostic and Therapeutic Facility. Section 3: Associated Equipment of Interest.
6. Approval of the NMDS survey was granted by the Chairperson of the NMDS, allowing the team
to proceed with actualizing the survey activities. 7.
The approved survey forms were shared with the IT department for them to use as the basis for creating the NMDS Database. The intention was for the Database to be ready for populating by
the time the completed survey forms had been returned by the SDPs.
8. Upon approval, survey forms were sent out to the Directors of relevant identiied SDPs to seek
voluntary participation into the survey. SDPs were identiied from the Malaysian Medical Health Directory MMHD and counter-checked by staff making the calls.
9. The project team was dependent on the SDP sites to ensure the survey forms were appropriately
distributed within their institutions. The project team then followed up with each individual specialty. The follow up was dependent on the availability of the specialty at the site with the
MMHD used as reference. Where there are uncertainties, the NMDS project team contacts the SDP directly to ascertain the availability of specialties.
A “service provider” of a particular specialty was deined as any participating site that provides specialists services respective to the discipline and includes sites that only provide visiting
specialist services. It does not require a resident specialist to be available at the site.
10. SDPs are meant to respond within a set deadline. Feedback is received either by fax or post prior
to Data processing. The NMDS project team also takes the initiative to pursue timely feedback from the respondents.
xix
Data Processing of Survey Data
1. Survey data was entered into the NMDS Database that had been created by the IT department based
on the inalized survey forms refer to Phase 1: 7 above. Drop down options similar to that in the survey form of each specialty was part of the database design to minimize data entry errors.
Prior to data entry, personnel were fully briefed on how to use the database and enter the data via a training event which included a demonstration.
Personnel were supervised whilst doing the irst few entries to make sure suficient competency had been developed to minimize if not eliminate errors.
A standard document on steps and precautions on Data entry was mailed to each personnel. Those who were unable to decipher the feedback were advised to enquire from senior staff.
Each entry is recorded for quality assurance purposes. 2.
Visual review and manual assessment of entries are performed to capture erroneous, inconsistent or inaccurate entries in the survey forms. These typically occur when information is entered under the
“Others” or “Shared Equipment” section. Follow-up with the SDP is performed where required.
Where data was provided using brand names, online searches or follow-up with the SDP was conducted to guide any required editing of the survey form data.
3. The populated Database then underwent Edit Checks, with the database entries being meticulously
crosschecked against the original survey forms.
4. It was then decided to exclude further data processing of a subset of devices reported by the SDPs
due to limitations in resources. The criteria for selection of devices to be reported per specialty were outlined by priority for treatment and quality of survey data available. Selection was done by the
NMDS project team with support from the Chairperson.
Only data on functioning medical devices were processed and reported. Functioning medical devices were deined as medical equipment that were used in daily procedures at the participating site and
excludes: • equipment deemed as in Beyond Economic Repair as well as
• equipment which, although were still in working condition, were non-operational not used at the site.
5. Data is then exported to Datamed Bio-Statistics for further data processing.
This included a speciic focus on estimation of missing data from poorly populated survey forms or non-responsiveness.
Datamed personnel were tasked with grouping and collating the NMDS data into forms and reports that would allow further study by the project team. These forms and reports were used by the team to
assess the quality of the NMDS data internally as well as with assistance from the expert panel.

Statistical Methods
In this report, the quantity of the availability of a device is expressed as in absolute count as well as in number per million inhabitants. The latter statistics are calculated as follows:
Where T is an estimate of the total quantity of the device available in the country in the year under consideration
P is the mid-year population of Malaysia or the relevant geographic region where the survey was conducted
T the total is estimated from the sample of relevant health care facilities as follows: The total is estimated by T =

Ь Where B is total number of beds in the population, b is number of beds of the responding hospitals
sample, b
i
is number of beds in the i
th
facility, and Ь the mean number of beds in the population. The sampling weight for each sampling unit or unit of analysis therefore has the following
components:
1. Probability of selection. The basic weight is obtained by multiplying the reciprocals of the probability of selection at each step
of sampling design.
