“Trauma work load of surgical intensive care unit

(SICU) at a university hospital in Pakistan - A six

month retrospective study”

TITLE OF THE STUDY

I N T R O D U C T I O N

Trauma is a worldwide public health problem.

It is the fourth leading cause of death in the western worldespecially in young population up to the age of forty.

Severe trauma, although small in number may need urgentlifesaving interventions.

Damage control surgical interventions & life sustainingorgan support in the intensive care unit consumesignificant resources and cause a huge economic burden tothe patient, healthcare system & society.

Introduction Continue

The 48 bedded state-of-the-art Emergency Department at Aga

Khan University hospital is a WHO Collaborating Center for

Trauma that handles around 60,000 patients annually.

The surgical ICU at the Aga Khan University has a capacity of

7 beds & major trauma victims requiring close monitoring or

organ support, with or without surgical interventions

constitute 30% of the admissions.

R A T I O N A L E

• Impact of trauma on our constraint resources in terms of

time, critical therapeutic interventions, advanced radiological

interventions, laboratory work load & blood product

utilization has not been previously documented in Pakistan.

• The results of this study will highlight the resources that are

required to safely & efficiently manage critically ill trauma

patients that can be utilized to plan future trauma

management facilities & improve the care of major trauma

patients in our country.

O B J E C T I V E

1. To identify trauma work load of SICU and to demonstrate

the resources utilized by the trauma admissions.

2. To compare the characteristics & outcome of trauma & non-

trauma patients.

M A T E R I A L & M E T H O D S

Settings:

SICU of Aga Khan University Hospital Karachi, Pakistan

Duration of the study: 6 months

Study Design: Retrospective study

S A M P L E S E L E C T I O N

Inclusion Criteria:

All adult admissions to SICU from 1st Jan 2014 till 30thJune 2014

Exclusion Criteria:

Age < 16 years

D A T A C O L L E C T I O N

• After Ethical Review Committee (ERC) approval, patientswere enrolled according to the inclusion & exclusion criteriadescribed above.

• Medical record numbers (MRN) of patients admitted duringthe study period were taken from the “admission recordregister” kept in the custody of the ICU head nurse.

• The variables collected from this register were age, gender,type of trauma, source of admission, length of stay in SICUand outcome.

Data Collection

Continue

Radiological investigations and interventions, laboratory

investigations, were collected from the Health information

management system (HIMS).

Blood and blood products utilized by patient were retrieved

from the blood-bank record.

D A T A A N A L Y S I S P R O C E D U R E

Statistical analyses performed using statistical software SPSS

version -16 (SPSS, Chicago, III).

Frequency & percentages were computed for qualitative

observations & analyzed by chi-square test. Mean & SD were

estimated for quantitative observations & analyzed by t-test. For

data which was not normally distributed Mann-Whitney U test

was used.

A ‘P’ value ≤ 0.05 was considered significant.

R E S U L T S

141 SICU admissions were reviewed. 22.7% (32/141) trauma

patients were identified during the 6 month study period.

Average age of the trauma cases was 35.81±13.11 years.

Male to female ratio was 7:1 in trauma cases.

Results cont…

Overall mortality of SICU was 39.7% and of the trauma

patients it was 31.3%.

Median length of stay was 5 (8) days [Median (IQR)].
