REPORT SUMMARY
This is the report on all intensive care admissions to the 31 participating centres from 1
January to 31 December 2009.
The following are the main findings:
1.

The total number of ICU beds in the 31 participating units was 330 with a bed
occupancy rate of 87%.

2.

The number of cases analysed was 21226, an increase of 12% over the previous
year.

3.


The overall reporting rate had been fairly constant at 89%.

4.

The percentage of patients denied admission due to the unavailability of ICU
beds had declined from 56.5% to 40.0% in the last four years.

5.

The average age of the patients, excluding those below 18 years, was 50.3 years.

6.

The average lengths of ICU and hospital stay were 4.4 and 14.4 days
respectively.

7.

In MOH hospitals, 62% of ICU admissions were non-operative patients.


8.

Direct admissions to ICU from the emergency department had increased from
9% in 2004 to 21% in 2009.

9.

62% of ICU admissions had one or more organ failure within 24 hours of
admission.

10.

Head injury, sepsis and community-acquired pneumonia were the three most
common diagnoses leading to ICU admission in MOH hospitals. This trend
had remained the same over the past 7 years. The in-hospital mortality rates for
this group of patients were 27.0%, 62.2% and 46.3% respectively.

11.


The average SAPS II score was 35.8, which carries a predicted risk of inhospital mortality of 28.0%.

12.

In MOH hospitals, 79.3% of patients received invasive ventilation with an
average duration of 4.3 days.

13.

The percentage of patients who received non-invasive ventilation increased
from 6.5% in 2003 to 13.3% in 2009.

14.

The incidence of VAP decreased by more than half, from 28.0 to 11.6 per 1000
ventilator days, in the last seven years.

15.

The crude in-ICU and in-hospital mortality rates were 21.2% and 29.7%

respectively.

16.

The mean standardised mortality ratio was 0.89, (95% C.I. 0.86 – 0.91).

FOREWORD
This is the 7th report of the intensive care database started in 2002, under the ambit of
National Audit of Adult Intensive Care Units (NAICU). Although there has been a restructuring of the organisation and even a name change (now called Malaysian
Registry of Intensive Care, MRIC), the activity of auditing the intensive care practice in
Ministry of Health hospitals has continued to grow and this report is the culmination
of that effort.
In the last two years, MRIC had faced uncertainties in funding and technical support.
Thankfully the problem has been resolved. The Malaysian Society of Intensive Care
(MSIC) is now the main sponsor of the activity while the Clinical Research Centre
(CRC) provides the backend server support and the Quality Unit, Medical
Development Division, the administrative assistance. This arrangement will
undoubtedly provide a conducive environment for future development.
I would like to express my utmost appreciation to my colleagues in the National
Technical Committee under the leadership of Dr. Jenny Tong, for their commitment
and hard work during this trying period. Not only has the MRIC persevered, it has
achieved remarkable success in migrating the electronic records from stand-alone
units to a web-based programme. In these seven years, the number of centres recruited
had grown from 14 to 31; the number of intensive care beds studied from 100 to 330
and the number of patients analysed from 7,000 to 22,000. This two to three-fold
increase is testament of the strength and success of MRIC.
Clinicians’ support has been, and will remain, essential to the future of the registry.
Ultimately, the purpose of the registry is to improve quality of care. The Anaesthetic
and Intensive Care Service in Ministry of Health, with the support of the
administrators and health managers has achieved improvement in access and patient
outcome. The percentage of patients denied ICU admission and the incidence of
ventilator-associated pneumonia have declined over the years. In the coming year, the
focus will be on other quality improvement activities such as central venous catheter
care bundle and skin care bundle. I am confident that similar trends in improving
patient safety will continue.

INTRODUCTION
The National Audit on Adult Intensive Care Units (NAICU) was established in 2002
as a quality improvement initiative to systematically review the intensive care
practices in Malaysia and where possible, to introduce remedial measures to
improve outcome. To date, this audit had published six reports and introduced
several quality measures such as ventilator care bundle, central venous care bundle
and ICU networking.
In 2009, the NAICU underwent a major re-organisation and was renamed the
Malaysian Registry of Intensive Care. This report is thus the second for MRIC, but
seventh in the series. Following the change, MRIC has now become a member of the
national registry under the purview of Clinical Research Centre, Ministry of Health.
The objectives of the MRIC are to:
1. Establish a database of patients admitted to the adult ICUs
2. Review the clinical practices of intensive care
3. Determine clinical outcome
4. Determine the resources and delivery of intensive care service
5. Evaluate the impact of quality improvement measures on patient care
6. Provide comparisons of performance of participating centres against national
and international standards
7. Conduct healthcare research related to intensive care
This report describes the intensive care practices and outcomes in an ICU in a private
hospital and 30 ICUs in MOH.
Data Collection and Verification
Data were collected prospectively in all 31 ICUs by trained nurses (source data
providers) and specialists (site investigators) based on a written protocol. Data
initially collected on a case report form for each patient was subsequently transferred
to a customised software called SyNapse.. At three monthly intervals, the data was
‘burned’ into compact discs and sent to the coordinating centre in Hospital Kuala
Lumpur for ‘data merging’.
All participating centres were to ensure “accuracy and completeness” of their
individual databases before being uploaded and sent to the coordinating centre.
Merged data were ‘cleaned’ and verified before being analysed using SPSS version
10.0.1.

17

This report is based on all admissions into the 31 participating ICUs from 1 January
to 31 December 2009. Those admitted during this period but were still in hospital on
31 January 2010, were excluded from the analysis. The total number of admissions in
2009 was 22,234, out of which 968 (4.4%) were readmissions. For patients with
multiple ICU admissions, only the first admission was included in the analysis.
Due to missing and inconsistent data, the sum total of some variables shown in the
tables may not add up to the actual number of admissions.
Data Limitations
Limitations to the registry data were mainly related to the data entry and collection
process. Some of the participating ICUs experienced rapid turnover of their site
investigators and source data providers resulting in data inconsistencies. Some
centres encountered problems in accessing their local electronic database due to
hardware problems. Due to logistical problems, the technical committee of the MRIC
was unable to verify missing and inconsistent data with the specific participating
centres and to perform site visits.
Format of Report
The format of this report follows the patient journey in four sections: demographics,
interventions, complications and outcomes. Information is reported on a total of
21,266 ICU admissions.
In this report, information was provided for individual centres. Wherever
appropriate, comparisons were made between categories of hospitals based on the
number of ICU beds. In MOH hospitals the categories were centres with 12 beds or
more and those with less than 12 beds. Where relevant, trends of certain variables
over the years were reported.
The Future
The year 2009 was the last, when electronic records were collected on respective
computers before being sent to the coordinating centre in Hospital Kuala Lumpur
for data merging. From 1 January 2010 onwards, data entry will be performed webbased using a standard e-case report form. Another 6 six new centres (Hospitals
Sungai Buloh, Ampang, Sultan Ismail Pandan, Sibu, Duchess of Kent Sandakan and
Hospital Wanita & Kanak-Kanak Sabah) will be added to the list of participating
hospitals in the MRIC.

The number of admissions has increased over the years. The increase from 2008 to
2009 was about 12%. There was an increase in number of admissions in most centres.
Hospital AS and Hospital TPG had increases of more than 100% in admissions
compared to the previous year. This was attributed to expansion of their ICUs in 2009.

The reporting rate is calculated by comparing the number of ICU admissions
reported to the MRIC and to the national census (collected by Anaesthetic program
head). The total number reported to the MRIC was slightly less than that to the
national census, as patients who were still in hospital on 31 January 2010 were
excluded in the analysis.
Overall, there was an improvement in the reporting rates from 82.4% in 2007 to 89%
in 2009. However, Hospitals KK. SP and MRI had poor reporting rates.

postoperative ventilation) as an indication for admission in MOH hospitals
compared to 1.3% in the private hospital. Non-operative intervention and

The definition of organ failure is based on the Sequential Organ Failure Assessment (SOFA) [1]

Figure 10:

Main organ failure on ICU admission, by hospitals 2009

In 2009, about a third of admissions to MOH ICUs did not have any organ failure in
comparison to the private hospital where two-thirds of admissions were without any organ
failure. In MOH ICUs, cardiovascular failure (39%) was the most common organ failure
during the first 24 hours of ICU admission, followed by respiratory (26%) and neurological
(20%). This is in contrast to 2003, where respiratory failure (57%) was the most common
organ failure followed by cardiovascular failure (19%).

Number of organ failure(s) on ICU admission 2009

In 2009, 38% of patients admitted to ICUs were without any organ failure, while 29%
had single organ failure. Many of the ICUs function as combined ICU/HDW and
this could be one of the reasons for the high proportion of patients admitted without
any organ failure.
