CHAPTER-III

RESEARCH METHODOLOGY

Research methodology includes Research approach, Research design, Variables, Description of settings, Criteria for sample selection. It further deals with Description of tool, Content validity, Reliability, Pilot study and Method of data collection.

RESEARCH APPROACH

An evaluate approach will be considered as an appropriate research approach to evaluate the effectiveness of garlic cloves on Blood pressure among patients with Hypertension.

RESEARCH DESIGN

The research design used in this study was quasi experimental design.

E O1 X O2

C O1 O2

E Experimental group

C Control group

O1 Pre test

O2 Post test

X Administration of garlic cloves

Variables

Independent variable: Garlic Cloves

Dependent variable: Blood pressure

Description of Setting

The study was conducted in primary health centre Rural area Alangium community which is 20km away from Sara Nursing College. In the primary health centre general ward facilities are available the population Alangium community 22,097 among them 12,054 are female, 10,043 are male.it consist of north street, and Muslim street. The people get medical aid from the primary health centre one primary school, and secondary school are there for educational purpose. Water and electricity facilities are available. The common occupation in the village in agriculture most of the people are coolie workers, going for construction work and other include and shop.

Study population

The population of the study was patients with Hypertension.

Sample

The Sample for this study was patients with Hypertension attending OPD at PHC, Alangium during the study period and those who meet the inclusive criteria.

Sample size

The total Sample size was 50.Among them 25 were assigned to experimental group and 25 were assigned to control group as per the convenience of the Researcher.

Sampling technique

Convenience sampling technique was used for this study.

Criteria for sample selection

The Sample was selected on the basis of following inclusion and exclusion criteria.

Inclusion criteria

  • Patient who are between 40 – 60 years of age.
  • Patient who are willing to participate in this study.
  • Both males and Females.
  • Patient with Blood pressure level between 140/90mmHg and 160/100mmHg.
  • Patient who are in anti-hypertensive drugs.

Exclusion Criteria

  • Patients with hypertension with other systemic illness.

DESCRIPTION OF TOOL

Section- A

Structured interview schedule for demographic profile

Structured interview schedule was used in this tool .It comprised of demographic data such as age, gender, educational status, religion, occupation. No score is given to this demographic profile. The data will be used for descriptive statistics.

Section- B

Structured interview schedule for Life style Questionnaire

A structured interview schedule was used to collect information regarding life style questionnaire such as, duration of illness, history of hospitalization, treatment, dietary pattern, food habits, exercise, recreational activities, family history of hypertension. No score was given in this section and it was used for descriptive analysis.

Section- C

Observational method to find out blood pressure by using Digital blood pressure monitor.

Digital blood pressure monitor was used to assess the blood pressure among patient with hypertension. According to the readings of Digital blood pressure monitor were classified in to normal, pre hypertension, stage I hypertension, stage II hypertension. Based on the category were given.

Table 3.1: According to joint national commission VII of early detection and treatment of hypertension, 2003

Blood pressure category

Systolic blood pressure

mmHg

Diastolic blood pressure

mmHg

Normal

<120

And <80

Pre hypertension

120-139

or 80-89

Stage I Hypertension

140-159

or 90-99

Stage II Hypertension

≥160

≥100

Content validity

Content validity of the tool was obtained on the basis of opinion of medical surgical experts [5 medical surgical nursing specialist,1 medical officer1,1 dietician]. The tool was found valid suggestions were incorporated.

Reliability

To ensure the reliability of the instrument, blood pressure was checked to 6 patients with hypertension. The reliability of the instrument was established by Inter-rater reliability method and the Karl Pearson coefficient formula was used to find the consistency of the tool.The obtained reliability co-efficient of systolic blood pressure (r=0.8), and diastolic blood pressure (r=0.9) Hence the tool was reliable.

Pilot study

In order to find out the feasibility and practicably a pilot study was conducted at Sanjay hospital, Palani for a period of 1 week (26.6.2013 to 1.7.2013) 6 patients with hypertension were selected (3 experimental group and 3 control group). Pretest was done for experimental and control group and intervention given for 5 days for experimental group and posttest was done for both groups. The study was found feasible to conduct.

METHOD OF DATA COLLECTION

  1. Ethical consideration;

Formal written permission was obtained from the medical officer of primary health centre Alangium. Oral consent of each individual was obtained before the data collection.

  1. Period of data collection

Data collection was done over a period of 4 weeks from 5.8.2013 to 31.8.2013

DATA COLLECTION PROCEDURE

The written permission was obtained from the medical officer (Dr.Bharathi) prior data collection. The samples were selected by convenience sampling technique oral permission was obtained from them after explaining the objective of the study. The 50 samples were selected know case of hypertension detected at PHC on the basis of convenience sampling technique. Approximately 8 samples was selected daily and 4 samples was allotted to control group and 4 samples was allotted to experimental group pretest was done for both groups. The researcher checked the blood pressure using Digital blood pressure monitor for both experimental and control group then the researcher daily visited the experimental group in home under the supervision of the researcher 10 grams of garlic cloves was given with after breakfast. For the control group the investigator assessed the blood pressure level and advised to continue the prescribed treatment. Posttest was done on 22 th day for both experimental and control group by using Digital blood pressure monitor.

PLAN FOR DATA ANALYSIS

The data was analyzed by using descriptive and inferential statistics. The following plans for data analysis were developed.

OBJECTIVES

STATISTICAL ANALYSIS

To assess the pre and post test systolic level of blood pressure among patients with hypertension in experimental group and control group.

Descriptive Analysis: frequency distribution , percentage.

To assess the pre and post test diastolic level of blood pressure among patients with hypertension in experimental group and control group.

Descriptive Analysis: frequency distribution , percentage

To compare the pre and post test systolic level of blood pressure among patients with hypertension in experimental group and control group.

Descriptive Analysis Inferential statistics: Mean ,Standard deviation ,paired ‘t’test

To compare the pre and post test diastolic level of blood pressure among patients with hypertension in experimental group and control group

Descriptive Analysis Inferential statistics:Mean,Standard deviation ,paired ‘t’test
