ABSTRACT The objective of the study was to describe the frequency of self monitoring blood glucose (SMBG) in non insulin type II diabetes mellitus, assesses the patients' behavior and responses, and to evaluate self reported medication adherence and investigate the patients' perception about the continuation of medication while diseases under control to improve the diabetes management. KEYWORDS: SMBG, Medication adherence Type- II diabetic mellitus a prospective study. 1. INTRODUCTION SMBG helps the patients to identify high and low blood sugar and react to the abnormal blood glucose values. The purpose of the SMBG is to collect the blood glucose levels at different time intervals and enable the maintenance of a more constant glucose level by more precise regimens. Frequency of SMBG varies from patient to patients.idf guideline for SMBG for type II diabetes recommend SMBG should be used only when individuals with diabetes (and /or their caregivers) and /or their health care providers have the knowledge, skills and willingness to incorporate SMBG monitoring and therapy adjustment in to their diabetes care plan in order to attain agreed treatment goals'' 1.IDF all so recommended SMBG should also be considered as part of ongoing diabetes self management education to assist people with diabetes to better understand their disease and provide a means to actively and effectively participate in its control and treatment, modifying behavioural and [1] pharmacological interventions as needed in consultant with healthcare provider. The first glucometer was patented in the year of Since then it was possible to monitor blood Vol 4, Issue 11, glucose more frequently, even in the domestic condition. Subsequently glucose self monitoring became an integral part of treatment. Self monitoring of blood glucose is essential for insulin treated patients with type1 diabetic (DM1) to adjust the insulin dosages. It helps to reach and maintain normoglycemia. Such treatments provide continuous control of blood glucose levels. [2] Type2 diabetes (DM2) has the complex pathogenesis and more progressive course than DM1.The gradual increase of glycosylated hemoglobin(hba1c) over time is observed. [3] However, evidence supporting the use of SMBG for patients with DM2. Not requiring insulin or treated with fixed dose. One of the first studies which documented beneficial role of SMBG was trial published by Devencianaet al. on gestational diabetes. The author compared the efficacy of postprandial vs preprandial monitoring in achieving glycemic control in women with insulin treated gestational diabetes. They proved that adjustment of insulin therapy, according to the result of postprandial, rather than preprandial blood glucose values, improves prognosis of pregnancy [4] however, the results obtained for gestational diabetes does not relate to the whole population of diabetic patients. Adherence with medication usage is defined as the proportion of prescribed doses of medication actually taken by a patient over a specified period of time. [5] Compliance, a synonymous term which was commonly used in the past, implies a passive role and simply following the demands of a prescriber and non-compliance has been regarded as associated with deviant or irrational behaviour. [6] Non-adherence or non-compliance, poverty, lack of knowledge and poor follow ups are the main factors observed in poor glycemic control. [7] Individuals with poor management of diabetes are at a greater risk of developing long-term micro and macro-vascular complications that lead to the damage of end organs such as kidneys, heart, brain and eyes, affects the direct and indirect health care costs and overall quality of life [8] Optimal glucose control can be achieved through strict adherence to medications, diet and lifestyle Adherence with medication usage is defined as the proportion of prescribed doses of medication actually taken by a patient over a specified period of time [9]. The aim of the study was to health care providers in RMMCH advice to Type II diabetic patients who are in stable glycemic control,regarding the frequency and timing of SMBG and evaluated self reported medication adherence and to identify the factors linked with poor adherence.

MATERIAL AND METHODS The institutional Human Ethical Committee of Annamalai University has been approved the study of being carried out at the Raja Muthiah Medical College and Hospital RMMCH. 12 Type 2 diabetic patients, which include 69 males and 51 females, were recruited as per the inclusion and exclusion criteria Patients who are regularly visiting hospital for the treatment from March 212 to May 213 have been taken as subjects for the study. Patients were recruited as per the inclusion and exclusion criteria Inclusion criteria Those patients are having the following categories only were recruited for the study a. Patients who diagnosed with Type-2 diabetes complications b. Patients with age of 3 years and above c. Fasting glucose 14mg/dl d. Postprandial blood glucose level (at 2hr) 2mg /dl e. Patients with associated diseases of Hypertension, Coronary artery diseases, Bronchial Pneumonia, Asthma, 2.2. Exclusion criteria a. Patients who diagnosed with outtype-2 diabetes complications b. Patients below the age group of 3 years. c. Patients who are not willing to participate in the study. d. Nursing or pregnant women. e. Hepatic or renal disease patients f. Patients with History of Ketoacidosis Patients were divided into three groups of 4 patients in each named as 1, 2 and 3. The 1 patients were treated with Metformin 5 mg whereas 2 was treated with Glimepiride 2mg and group 3 treated with combination therapy of Glimepiride 2mg with Metformin5mg 2.3 Data collection The data collection and documentation of patient profile form was designed which includes information on patient's demographic details (e.g. Patient s Name, Age, Sex, employment and date of admission for in patients and out patients review dates presenting complaints, provisional/confirmed diagnosis, social history, current medications, laboratory test reports Vol 4, Issue 11, 2.4 Measures The SMBG assessment and frequency has been assessed during pre designed questionary a framework of (sonupoulse.,et al 211) were measures using 95% confidence interval.adherence to treatment has been assessed during a personal interview with each patient using a questionnaire. (Each patient takes 1 minutes to complete) medication adherence to diabetes medicines was determined using a modified version of the four items,self reported Morisky medication adherence scale (11) Each item is in Yes/no format with a maximum possible score of four equating very poor adherence and consider as good adherence Table 1: Socio demographic characteristics of patients.

Diabetes and associated complication a major health care burden worldwide. Males predominate in the study population, which is an agreement which results of various other studies in India [1] and United states educational status The higher prevalence in younger age group may be due to the lifestyle of the younger population and also the stress factor which unmasks diabetes causing blood sugar to rise. [16] The level of education and place of residence are important determinants of how quickly a diagnosis will be made. Level of education and economic status can have a positive and negative impact on the quality of life of diabetes patients, as a result, on the level of metabolic control. Satisfaction with treatment and quality of life are positively associated with employment and a higher income. People with lower education levels and unemployment persons, have, in general, a lower satisfaction with life and are less satisfied with diabetes treatment, as well as having worse metabolic control. [17] In the study was found more in secondary education with higher prevalence rate 36.66% in the employment status unemployed patients had more prevalence to 56.6% than employed 29.16% The duration of diabetes plays an important role in the management of diabetes.the study showed that most of the patients of years patients with a long duration of diabetes mellitus developed complications [12] In the present study, only 36 (78.26%) of the subjects had better glycemic control.a total 54 patients suffered from Co-morbid conditions, the most common which were Hypertension (27.5%) peripheral neuropathy (17.5%). This study finding consists with similar study hypertension is a more complication affecting 2-6% of people with diabetes. [13] A four item modified Morsiky adherence predictor scale used to assess medication adherence. It is a self report method. The assessment of patients' response to the 4 items modified Morsiky adherence predictor scale [15] showed that 39.65% (N=46) of the patients had good adherence with prescribed medications whereas 36.2% had medium adherence,and 24.13% had low adherence. Medication adherence is a key component for patients with diabetes. The present study has found a high rate of good adherence in male (46.37%) than female. This result consists with similar study, conducted among Americans in which men scored higher than women on self care adherence [14] Vol 4, Issue 11, The side effect of drugs which is considered as a factor for non- adherence appeared with 6.3%. In the present study, 53.44% patient with Inadequate knowledge regarding therapy was found. The identified cause of non-adherence to take antidiabetic medications as prescribed forgetfulness, when felt better, when felt worse others Hypoglycemia were found to be 12.93%, 33.62%, 31.89% and 1.34% A study identified busy work schedule, especially for patients in the working population as one of the reasons for not taking their anti diabetic medication as prescribed was found to be 12.93% and forgetfulness is a widely reported factor that cause non-adherence with medication. Which are lower than the study conducted in Nigeria. [15] 4. COLUSION Diabetes mellitus is one of the disorder, we cannot cure the diseases.but it can be controlled with the help of oral hypoglycemic drugs, Physician and pharmacist improve the areas of patient education and medication counselling. Encouraging the patients to monitor the blood glucose in house using (SMBG), instructed to note in the diary every review visit checks the blood glucose status to adjust the dosage, diet, and modulation of exercise and all so to educate the importance of SMBG in management of diabetes mellitus.the habit of doing SMBG reduced the symptoms related diabetes complications.
