Assessment Of Insulin Adherence And 1Insulin-related Knowledge Among DiabeticPatients In Hospital Sultan Ismail,Johor Bahru Volume 10Teoh L.R1, Lee C.Y2, Wasli M.3 20121,2,3 Hospital Sultan Ismail, Johor Bahru.BACKGROUND Insulin is one of the most commonly prescribedDiabetes mellitus is an important public health concern medications in the hospital as it can be the most effectiveboth nationally and internationally, due to the increase in drug to achieve glycemic control and prevent long-termits prevalence and its social and economic results, such as comorbidities. The invention of insulin pen devices (ieimpairment in productivity, quality of life and survival of HumaPen) offers safety, convenience and flexibility, withindividuals, early retirement, high treatment costs and higher acceptability by the patients especially among thecomplications.1,2 The World Health Organization elderly. The Joint Commission on Accreditation of(WHO) reported that 171 million people were living with Healthcare Organizations identified insulin as one of fivediabetes mellitus in the year 2000, and that amount is “high alert” medications that have the greatest risk ofestimated to double by the year 2030.3 In Malaysia, the causing injury to patients because of medication errors.13prevalence of type 2 diabetes for those aged above 30 Insufficient knowledge of insulin and diabetesyears was 14.9% in the year 2006. The overall prevalence management on the part of health care providersof diabetes increased by 80% over a decade (8.3% in contributes to errors in insulin use. Consequently, it mayNHMS II year 1996 vs 14.9% in NHMS III year 2006) lead to dangerous but preventable adverse patientrepresenting an average 8% rise per year.4 outcomes such as hyperglycemia and hypoglycemia.14 The present study focuses on patients' medicationAccording to World Health Organization Adherence adherence level and insulin-related knowledge; with the(2003) and Koneru et al. (2008), medication adherence ultimate goal of promoting effective and safe use ofcan be defined as the situation to which a person's insulin therapy by improving patients' insulin-relatedbehavior corresponds exactly with medical or health knowledge, minimizing insulin-related adverse effects,advice as directed.

A Study Of Obesity Among 7 Health Staff At Kulaijaya District Volume 10 Health Department (2012) 2012 Dr. Mohd Shaiful Ehsan B Shalihin Poh Lin Chin, Misringaton Kulaijaya Health District JohorOBJECTIVE: To study and report prevalence of the environment which include education background, occupation, household income, culture and lifestyleoverweight and obesity among health staff at Kulaijaya (Azmi, et al., 2009; Moy & Atiya, 2003-2005; Richard, Andrew, & Rodolfo, 2012; Shashikiran, Sudha, &District Health Department and describe their association Jayaprakash, 2004; Speakman, 2004). Globally, around 12% of adults aged 20 and above were obese in 2008with gender, marital status, respective job scope and (World Health Organization (WHO), 2004). This figure is increasing in developing countries including Malaysiaworking environment, using standardized international (Caballero, 2001; Moy & Atiya, 2003-2005; Nor, et al., 2008; Shashikiran, Sudha, & Jayaprakash, 2004). Baseddefinitions. METHODS: This cross on the National Health Morbidity Survey (NHMS) III (2006), the national prevalence of obesity (BMI 18.5-sectional study studied body mass index of all the health 24.9 kg/m2) was 14% compared to 4.4% in NHMS II in 1996 (Nor, et al., 2008). Rapid pace of industrializationstaff of Kulaijaya Health Department except expectant and urbanization in recent decades in Malaysia had brought in changes in the lifestyles of Malaysians (Moymothers and females in their first three months FM, 2003-2005). These include reduction of physical activities, changes in dietary habits and food preferences.postpartum period. Body mass index (BMI:kg/m2) was Generally, Malaysians acquired a taste for high in fat, processed fast food and high calorie diets. Furthermore,calculated from measured weight and height, using housewives showed the highest prevalence of obesity at 20.3% (CI 0.19–0.21), compared to working mums whocalibrated weighing scales and body meters. Body weight engage in regular physical activity (Nor, et al., 2008). Obesity has also reached an alarming level at the southernclassifications were defined as follows: According to region of Peninsular Malaysia, specifically Johor, as the prevalence is highest in this state compared to otherWHO Expert Consultation 2004 for Asian BMI: states. According to the findings of the Malaysian Adult Nutrition Survey in 2009, prevalence of obesity in Johorunderweight (BMI < 18.5), normal weight (18.5 to 24.9), is at 13.81% (CI: 0.12-0.16) (Azmi, et al., 2009). The mean body weight was also significantly higher in thepre-obese/overweight (BMI 25.0-29.9), obese (BMI > or southern region (64.42 kg) (CI: 63.46), compared to those in Sarawak (60.66 kg) (CI: 59.43, 61.88)] and Sabah= 30.0). Otherwise, 100% respondent's rate was achieved. (58.93kg) (CI: 57.86, 60.01) (Azmi, et al., 2009). Even though obesity is higher in females 17.4% (CI 0.17-0.18),Descriptive and correlation analysis were performed it is unequally distributed by comparing regional factors and ethnic groups. This finding was attributed tousing SPSS version 15. A significance level of p-value underlying individual socioeconomic role (Nor, et al., 2008)(Richard,Andrew, & Rodolfo, 2012).less than or equal to 0.05 was considered statistically Currently, obesity and overweight are serious emerging global issues among healthcare personnel. A study of 760significant (p < 0.05). nurses across 6 different states of United States found 54% to be overweight or obese (Miller, Alpert, & Cross,RESULTS: The prevalence were found to be 5.8% for 2008). In addition, there were hospitals which implement policies barring the employment of obese candidatesunderweight (CI 0.03-0.10), 40.2% for normal BMI (CI (Miller J. R., 2012). In Johor, the prevalence of overweight and obesity among health staff was even0.33-0.47), 33.9% for overweight (CI 0.27-0.41) and higher than national prevalence of 60% (Harian Metro, 2009).20.1% for obese (CI 0.14-0.26). Higher prevalence ofobesity was found in males (20.1%) (CI 0.13-0.32), thoseconfined in office settings (23.3%) (CI 0.14-0.35) and inmarried employees (20.6%) (CI 0.15-0.27). There was asignificant association between marital status andoverweight (P 0.023). Among all job scopes, medicaldoctors had the highest prevalence of obesity (38.5%)(0.18-0.64). Prevalence of normal weight andunderweight are higher in those working in clinicalsetting (46.5%)(CI 0.38-0.55) compared to office staff(45.0%) (CI 0.33-0.58).CONCLUSION: There was higher prevalence of obesityand overweight amongst male staff, office andinspectorate personnel and medical officers at KulaijayaDistrict Health Department in relation to national andstate figures. Regular weight management programshould be implemented to all staff regardless of gender,marital status, job scope and working environment.KEYWORDS: Obesity, health staff.INTRODUCTION:Obesity is a complex chronic disease that results frommulti factors such as interaction between genotype and 28

There are many ways to measure body fat content in answer. It was mandatory that all staff partook in thiswhich the body mass index (BMI) (defined as study and respondents' rate was set and achieved at 100%.weight/height² [kg/m²]) is the most widely used This study is used to measure the prevalence of body masscompared to other weight-for-height indices.

These figures can be attributed to the location of CONCLUSION :Kulaijaya itself which is just next to Johor Bahru, a fast There was higher prevalence of obesity andgrowing urbanized and developed capital city inMalaysia (Noorsidi, 2009). Urban food environment, overweight amongst male staff, office and inspectoratebuilt environment and technology advancements can lead personnel and medical officers. Nevertheless, theseto poorer diets and less physical activity (Harvard School findings were found to be insignificant.

This is probably due tohigher physical activity required to run clinics rather than ACKNOWLEDGEMENTSoffices. Furthermore,office work is mostly related with In The Name of Allah, The Most Gracious and Merciful.paper work and entails prolonged sitting rather than We are so blessed with all the courage and strength thatstanding (Ariënsa, et al., 2001).

Wefindings are similar with previous studies (Jeffery & pray that Allah will reward your benevolence andRick, 2002; Lipowicz, Gronkiewicz, & Malina, 2002; cooperation in this world or the hereafter.Sobal, 2008). This might be due to significant changes inlifestyle as a couple automatically cease to monitor orcontrol their weight gain or body shape after marriage.Married couple spend more time eating together andoften order takeaway ready meals while exercising less(Hough, 2010). Surprisingly, medical doctors have the highestprevalence of obesity among all categories in this study.This might be due to their job scope in clinical settingwhich were most likely related with counseling patient,establishing long term relationship with patient andfamily members, emphasizing disease prevention andhealth promotion (American Academy of FamilyPhysicians, Wikipedia) rather than attendance orinvolvement in acute or emergency cases as in a hospital 31

Appendix 2Rosendaal Method for % INR in range - method which INR-specific person-time is calculated by incorporating thefrequency of INR measurements and their actual values, and assuming that changes between consecutive INRmeasurements are linear over timeExample: Patient has INR reading of 2.4 on October 1st, then reading of 3.2 on October 17th. Assuming the patientgradually moves towards a reading of 3.2 throughout the 16-day period between Oct 1st and Oct 17th, then we canestimate that the patient was within their INR therapeutic range [2 - 3] for a majority of that time period. To calculate thevalue1. calculate amount of the total shift (2.4 to 3.2 = 0.8 increase) that is within the therapeutic range (0.6 of shift is withinrange, [3.0 - 2.4 = 0.6])2. calculate percent of total shift within therapeutic range (0.6/0.8 = 75%)3. estimate number of days since last visit that were within range (75% x 16 days since last visit = 0.75 x 16 = 12 dayswithin range, 4 days out of range). Percentage for that time period is 75% in range, and 12 total days in range.To calculate overall % in range, add total days in range for each time period, and divide by total therapeutic days Sample Patient Visit Date Type INR Days INR Pred% In Since Diff Range 12/20/2005 8:29:19 AM Prior Visit 3.3 50% 100% 1/17/2006 8:32:38 AM Onsite Training 2.7 28 -0.60 100% 100% 2/7/2006 8:32:38 AM Prior Visit 2.3 21 -0.40 67% 3/7/2006 8:32:38 AM Prior Visit 2.4 28 0.10 0% 0% 4/4/2006 3:54:57 PM Scheduled Visit 2.2 28 -0.20 48% 0% 4/12/2006 10:48:08 AM Telephone Contact 1.9 8 -0.30 0% 56% 4/25/2006 4:31:10 PM Scheduled Visit 1.2 13 -0.70 57% 100% 5/2/2006 3:18:50 PM Scheduled Visit 1.8 7 0.60 71% 71% 5/15/2006 3:51:58 PM Scheduled Visit 3.9 13 2.10 100% 5/22/2006 3:39:23 PM Scheduled Visit 3.7 7 -0.20 5/30/2006 3:42:20 PM Scheduled Visit 3.5 8 -0.20 6/14/2006 2:42:54 PM Scheduled Visit 1.7 15 -1.80 6/23/2006 3:09:33 PM Scheduled Visit 2.4 9 0.70 7/25/2006 2:50:16 PM Scheduled Visit 2.5 32 0.10 8/22/2006 2:49:09 PM Scheduled Visit 3.2 28 0.70 8/29/2006 3:07:13 PM Scheduled Visit 2.5 7 -0.70 9/19/2006 3:03:26 PM Scheduled Visit 2.3 21 -0.20 INR In Range % (Traditional) = 47.06% [8 visits within range out of 17 total visits] INR In Range % (Rosendaal) = 71.05% [194 days in therapeutic range out of 273 total therapeutic days] 41
