Abstract: Introduction. insulin is a valuable drug for, those who are in need of it. Insulin will have tremendous impact, when used properly. Intensive insulin therapy was essential in the maintennce of strict glycemic control among insulin requiring patients with diabetes. However this presents challenges in the face of the complexities associated with insulin use and also taking in the consideration the potential danger associated with inappropriate use. Insufficient knowledge and attitude of insulin self administration can result in preventable complication, adverse patient outcome, poor adherence to therapy and invariably poor glycemic control. Objectives. to assess knowledge and attitude on insulin self administration among type 1 DM patients in Mekele hospital 2015. Methodology. Institution based descriptive cross sectional study was conducted. The study subject where type 1 DM patients in Mekele hospital (attending chronic follow up).Data was collected by interview using pre - tested structured questionnaires. The data was entered and analyzed using SPSS version 16. All type one DM patients were included in the study. Result. among 141 respondents, more than half 78 (55.3%) of them had average knowledge and majority 96 (68.0%) of the participants had favorable attitude. Conclusion and recommendation. the finding of this showed that type 1 diabetic patient had average knowledge and favorable attitude towards self administration of insulin injection. It is suggested that more should be done on areas like medias, health professionals on health education towards insulin self administration for type 1 DM patients.

Keywords: Knowledge, Attitude, Insulin Self Administration


1. Introduction

Diabetes is a public health problem which is a chronic disease and is now as an epidemic in both developed and developing counties. DM is recognize d as one of the leading cause of death and disability worldwide The physical social and economic factors involved in the management of diabetes are a continuous strain for health sector as well as to government agencies While there has been a great improvement in the knowledge, epidemiology and management of this condition in the developed world, there has been little or no improvement in sub - Saharan Africa including Ethiopia.[1]

Insulin is one of the harm full medications if used inappropriately. For this reason, it is identified as one of the five "high alert" medications that have the greatest risk of causing injury to Patients because of medication errors. [2,3]

Intensive insulin therapy is essential in maintenance of strict glycemic control among insulin requiring patients with diabetes. However this presents a challenge In the face of the complexities associated with insulin use and also taking in to consideration the potential dangers associated with inappropriate use. Insufficient knowledge of insulin self injection can result in preventable complication, adverse patient out came full adherence to therapy and invariably poor glycemic control [4]. Many insulin requiring diabetes patient possess poor knowledge of insulin use are conversant with some important terms such as keto - acidosis, insulin reaction hypoglycemia. [5]

It is a growing concern worldwide; while there has been a great improvement, in the knowledge, epidemiology and management of this condition in the developed worlds, there has been little or no improvement in sub Sara Africa including Ethiopia [1]

Knowledge about insulin self administration is a fully requests for individuals and communities to take action for control of diabetes the treatment for type 1 diabetes (IDDM) is inject able insulin therapy which requires coordination and understanding of both the individuals with diabetes and those responsible for diabetic care. The diabetes patients who are on insulin need to be knowledgeable regarding the disease and insulin therapy and also they must have a competency and positive attitude towards self administration of insulin injection to overcome the barriers of insulin injection and to have good glycemic control. Patients need knowledge to improve the competency level of self administration of insulin which in turn will help in better glycemic control and avoid complications. Glycemic control and prevention of complication will reduce the cost of treatment and diabetes related mortality [6]

The long term prognosis of type 1DM is said to improve with a complex demanding and often intensive regimen and maintenance of lower blood glucose level is said to reduce the risk of long term complication by as much as 60% [7].

Many studies conducted elsewhere in the world on insulin therapy have showed that the knowledge and awareness about the disease can have positive influence on knowledge and attitude of patients regarding Insulin Self - administered that could lead to better management of diabetes and eventually good quality of life. However, knowledge and attitude gap exists in type 1 diabetes mellitus management that does not allow patients and healthcare professionals to implement life style changes could reduce the morbidity and mortality associated with diabetes.

Diabetes is one of the major causes of premature illness and death worldwide. More than 80% of diabetes death occurs in low and middle - income countries. In our study area, Mekele hospital health professionals alone can’t provide high quality care.

Diabetes being a chronic illness requires sound knowledge and attitude of self insulin administration by patients, so that they can contribute meaningfully in the management of their lives. However there was no enough study conducted on knowledge and attitude of insulin self administration among type 1 DM patients.

The study has been conducted to assess the knowledge and attitude of insulin self administration with type 1 DM patients in Mekele hospitals. The findings of this study will help in identifying population knowledge gap and their attitude towards insulin self administration which might help in designing effective educational program for safe insulin self administration and also will be used as a base line in the future for further study.

ITEM AGREE NOT SURE DISAGREE
Frequency (%) Frequency (%) Frequency (%)
Insulin cause other health problem 31 (22) 25 (17.7) 85 (60.2)
Insulin self - administration correctly Decrease glucose in the blood 66 (46.8) 52 (36.8) 23 (15.6)

Out of 141 type 1 diabetic patients included in this study, 95 (67.4%) had favorable attitude and 46 (32.5%) had un favorable attitude. The mean attitude score of the participants was 3.07 with maximum score of 15. This result showed that most type 1 participant had favorable attitude on insulin self administration.

5. Discussion

The study was carried out to assess the knowledge and attitude of type 1 diabetic patients on insulin self administration in Mekele hospital. The study showed that the mean knowledge score of study subjects were 7.27. Study participants had average knowledge regarding insulin self administration. This study had demonstrated average level of knowledge regarding insulin self administration. The prevalence of knowledge was lower compared to studies done in India and Bangalore which were 68% and 86.7% [6,8].This difference from the previous studies might be due to high illiteracy rate of study participants, lack of self insulin injection education facilities and low access of media and NGOs in awareness creation about insulin self administration..

Of the study participants thought that diabetes mellitus mean high blood sugar. This was better than a similar study done in Bahir Dar, Fellegehiwot hospital which was 33.4% [9]. This difference may be related with patient health profile difference

Majority of type 1 diabetic patients (82%) awarded that the action of insulin is to lower glucose in the blood. This study was supported by similar study conducted in Bangalore (80%) [8].

Another important finding of this study was a limited knowledge about the complication of insulin therapy (10%), which was much lower compared to studies done in Bangalore (86.67%) and Nigeria (66.4%) [8,10]. this difference might be due to high illiteracy rate, environmental factor and socio economic status of the study participant of the present study. This level of inadequate knowledge regarding complication of insulin therapy may lead to decrease awareness of patients for complication and these are high economic burden of the country in the management of complications which comes due to inadequate awareness of the complications and lack of adequate organized heath education about diabetes.

Participant aware the sites of insulin injection are abdomen, thigh, glutei and deltoid. This finding was different from a study conducted in Bangalore, which was 53.3%. [8] This could be lack of organized health education and negligence of health care workers on insulin self administration. Inadequate knowledge regarding site of insulin injection may lead to develop complication of insulin therapy. These findings high light the need of emphasizing insulin injection during diabetes education.

Among respondent, 68.6% knew an open vial could be preserved in refrigerator or cold place. This study had slight different from study conducted in Indian and Bangalore 72.4% and 78.33% respectively. [6,8] This difference from the previous studies could be low economics status of study subjects and health patient negligence to educate about insulin vial preservation.

The mean attitude score of the study subjects was. Participants had favorable attitude and study participants had favorable attitude and study participants had unfavorable attitude. It was lower compared to study done in Bangalore, which was 81.7% had favorable attitude. 18.3% had most favorable attitude and none of them had unfavorable attitude. [8] The difference from Bangalore finding might be lack of trained man power to create adequate awareness toward insulin therapy. The present finding was better than another study conducted in India which was only 32% had favorable attitude and others had unfavorable attitude towards insulin self administration. [6] This difference might be due to environmental and socio - cultural factors of participants

Limitation of the study

This study was also limited to diabetic patients who were on subcutaneous insulin therapy and only site was included in Mekele hospital (chronic follow up).it assessed only their knowledge and attitude practice was not included. We did not observe what actually do while they insert insulin

6. Conclusion

The finding of this study showed that type 1 diabetes patients had average knowledge and less favorable attitude among type 1 diabetes toward insulin self administration but there is still there is a gap on knowledge and attitude of type 1 diabetes patients on insulin therapy.

Recommendation

To Medias; most of the patients get the information from health workers, there is still knowledge gap so that it is better to deliver updated information from the media.

To health science professionals: at the time of follow up strict education has to give for each patient in order to increase their knowledge, attitude and practice.
