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.

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.

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.

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.

METHODOLOGY

Research design: Pre – experimental; one group pretest and post test.

Setting: Medical and surgical wards of Chettinad hospital and

research institute. Kelambakkam.

Population: All the patients who were confined to bed during the

period of data collection in the Chettinad Hospital and Research Institute.

Sample: The patients who were confined to bed more than

48 hours ,who fulfill the inclusion criteria. 5

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.

Description of the toolSECTION 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 .

DATA ANALYSIS 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

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)

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.

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.

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.

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.
