A study to assess the effectiveness of structured
teaching programme on knowledge regarding
prophylactic measures in prevention of Deep Vein
Thrombosis among patients confined to bed in Tertiary
hospital, Chennai, Tamilnadu, India.

2. NEED FOR THE STUDY
• A world wide survey conducted by WHO showed that
Deep vein thrombosis is a common disease with an
average incidence rate of more than one per thousand
populations,25% of those are having recurrence and
many patients in hospital are at increased risk of DVT,
where immobility predisposes a person to thrombosis.
• Prevention is better than cure –Having identified patients
at high risk of DVT, the researcher found that it is
relevant to conduct a study to evaluate the effectiveness
structured teaching programme on the prophylactic
measures in the prevention of deep vein thrombosis.

3. OBJECTIVES
• To assess the pretest knowledge on the prophylactic
measures in prevention of deep vein thrombosis among
patients confined to bed .
• To determine the effectiveness of structured teaching
programme on the prophylactic measures in prevention
of deep vein thrombosis among patients confined to bed.
• To find out the association between the post test levels
of knowledge regarding the prophylactic measures in the
prevention of deep vein thrombosis among patients
confined to bed with the selected demographic variables.

4. HYPOTHESIS
H1
There is a significant difference between the
mean pre test knowledge and post test knowledge
scores regarding the prophylactic measures in the
prevention of DVT among patients confined to bed,
after the structured teaching program.
H2
There is a significant association between the mean
post test knowledge and the selected demographic
variables.

6. METHODOLOGY
CONT….
Sampling technique
Purposive sampling technique.
Criteria for sample selection:
Inclusion criteria:
• Patients who were confined to bed more than 48
hours.
• Patients who were willing to participate.
• Patients who were able to communicate in English
and Tamil.
Exclusion criteria:
• Patients who had altered sensorium.

7. Description of the tool
SECTION A:
Structured questionnaire consists of open ended and closed ended questions
to elicit the demographic data. It includes age, sex, gender, occupation, monthly
income, and any underlying risk factors of deep vein thrombosis.
SECTION B:
This consists of questions which consists of 20 multiple choice questions
regarding the definition, causes, the signs and symptoms and the prophylactic
measure in the prevention of deep vein thrombosis, each consists of three choices
and one which is the correct answer.
SECTION C :
This consists of the structured teaching programme given to the patients
confined to bed regarding the prophylactic measures in the prevention of deep vein
thrombosis such as passive exercises, banding, foot elevation, leg exercises, and
avoidance of high vitamin k foods, and life style changes like reducing weight,
avoiding smoking and control of blood pressure .

8. DATAANALYSIS AND INTERPRETATION
ORGANISATION OF THE FINDING
The data collected from the subjects were organized and
presented under the following sections
Section I: Distribution of sample characteristics
Section II: level of knowledge of patients confined to bed about
the prophylactic measures the in prevention of deep vein
thrombosis
Section III: Effectiveness of the structured teaching programme
regarding prophylactic measure in the prevention of deep
vein thrombosis.
Section IV: Comparison of the pretest and the post test
knowledge of the of patients confined to bed about the
prophylactic measure in prevention of deep vein thrombosis
Section V: Association between post test knowledge score with
the selected demographic variables

14. SECTION 5: ASSOCIATION BETWEEN THE POST TEST
KNOWLEDGE WITH SELECTED DEMOGRAPHIC
VARIABLES
• The post test score was not associated with the
above demographic variables except for
occupation and history of blood clotting
disorders.
(P<0.05)

15. DISCUSSION
• There was a significant difference in the knowledge on
prophylactic measure in the prevention of deep vein
thrombosis in the patients confined to bed after teaching.
• There was no significant association of post test
knowledge on prophylactic measure in the prevention of
deep vein thrombosis in the patients confined to bed
score with the selected demographic variables except for
occupation and history of blood clotting disorders.
• The above results indicate that the structured teaching
programme have a significant effect in improving the
knowledge on the prophylactic measure in the
prevention of deep vein thrombosis in the patients
confined to bed.

16. RECOMMENDATIONS
Based on the findings of the study, following
recommendations are put forth.
•A similar study can be conducted in a community
setting.
•An experimental study can be done to assess
the other new prophylactic measures in the
prevention of the deep vein thrombosis.

17. LIMITATIONS
There were few limitations in the study. They are
as follows:
• Only selected aspect regarding prevention of
deep vein thrombosis were selected for the
study.
• The researcher could not get a standardized
tool to assess the knowledge on the
prophylactic measure in the prevention of the
deep vein thrombosis.

18. CONCLUSION
Data depicts that the mean post test
knowledge score was higher than the mean pre
test knowledge score.
This indicates that structured teaching
is effective in increasing the knowledge score
of the patients confined to bed on the
prophylactic measure in the prevention of deep
vein thrombosis.
