Diabetes mellitus has been recognized as a demanding disease that requires urgent attention from all health care providers to address its prevalence and related complications. It is considered as a top 10 cause of death globally. ( Oguntibeju, (2019).) Poor control and hyperglycemia lead to many complications resulting in increased mortality, morbidity, increased utilization of the health care system, reduced quality of life, and life expectancy. (American diabetes, 2017) (American diabetes association, 2020 )
The prevalence of diabetes mellitus (DM), in Saudi Arabia, is growing. One-fourth of adult is affected by diabetes, which is further predicted to rise to more than double by the year 2030. ( Alzaheb, 2018 ). Also nearly half of diabetes exhibited a low level of functional health literacy had low diabetes self-management. (Almigbal, 2019). The American Diabetes Association (ADA) recommended an HBAC goal of less than 7% for most adults with diabetes. ( ( Skyler, J.,2009 )
Despite the availability of diabetes care clinical practice guidelines, diabetes is poorly managed resultto resulting in complications and unnecessary costs (Nazir, M., 2018). A hospital-based cross-sectional study among randomly selected 258 type 2 diabetic adults concluded that 70.8% had a poor status of glycaemic control, educational level and longer duration of diabetes were significantly associated with increased odds of poor glycaemic control. (Abera, 2022 ). In the UK Prospective Diabetes Study (UKPDS), newly diagnosed with type 2 diabetes followed for 10 years, with intensive control (median HBAC 7.0%) was found to reduce the overall microvascular complication rate by 25%, uncontrolled glucose levels were associated with substantial mortality and cardiovascular disease. ( Navarro-Pérez,2018) (Manley, S. 2003). Uncontrolled diabetes is associated with cardiovascular disease (CVD). Which leads to significant morbidity and premature mortality, the greatest cause of death in people with diabetes is CVD, good glycaemic control decreases the cardiovascular risk by 42%, 60 % with an intensive reduction of HbAC. ( American Diabetes Association, 1999 ) ( Genuth, S., 2006 ) ( Skyler, J.,2009 )
Our findings showed that more than 20 % of our patients are illiterate, the mean duration of diabetes is more than 13 years and the mean HbAC is more than 9 . with a mean HBAC of more than 9 most of our cardiac patients had uncontrolled diabetic, about 37 % of our intervention group have impaired renal function - Creatinine clearance less than 60 ml\min, all of uncontrolled diabetic and impaired renal function increase the cardiovascular risk and complication. More than 60 % of our diabetic, cardiac patients had poor adherence to their medications. (Table 5 ) With more duration of diabetic disease cardiovascular risk increases and that is clear with more than 12 years of diabetic duration in our cardiac patients.Our intervention group showed that about 21 % need adding another drug, 18 % need Insulin to be added, 40.5% of our patients needed a change in doses, more than 60 % had poor medication adherence and more than 21 % were illiterate. ( Figure 4 ) These results highlight the need for a multidisciplinary approach to the management of patients focusing on associated factors identified for poor glycemic control to maintain good glycemic control and improve outcomes, our findings from our study and previous studies showed that the clinical Pharmacist as a member of a multidisciplinary team has important roles in diabetes management to achieve the goal of treatment, decrease mortality and morbidity, improve quality of life, and delay complication by education, counseling on drug, disease, diet, exercise, smoking cessation and lifestyle modification, self-management, an assessment and adjustment of anti-diabetic medications, identifying and solving drug-related problems in co-operation with physician and other diabetes health care team. (Figure 5 ) All of these interventions helped in improving glycemic control, provided the more advanced diabetes services as pharmacists reviewed the patient’s drug re-fill history and identified poor adherence, and helped in identifying the barriers to medication taking in diabetic patients
In this study and all other studies, it was proven that the intervention was successful in achieving the goals of HbAC in diabetes patients and reducing the complications, improving diabetes self-management and adherence to diabetic medication. Therefore, integrating the clinical pharmacists into a health care team had shown to be effective in improving the outcomes in diabetic patients. (Demoz, 2018) (Van Dril, 2019)( Kharjul,2018) (Powers,2020) ( Willens , 2011) . The American Diabetes Association Standards and the International Diabetes Federation (IDF) recognize pharmacists as one responsible for teaching self-management practices, reviewing the treatment plan, optimizing medication therapy, promoting adherence to medication and blood glucose monitors, referring diabetic patients to other healthcare services when needed which help in decrease health care cost and utilization. (Dickinson, ,2019) (El Hajj,,2018 ). A study by Presley, 2019 concluded that clinical pharmacists have a role in diabetes care to enhance medication adherence. ( Presley,2019) In this study about 63 % of our patients had bad medication adherence, involving of clinical pharmacist in patients care can improve adherence by patients counseling and explain the importance of medication and the importance of good glycemic control to the patients
In the hospital, both hyperglycemia and hypoglycemia are associated with adverse outcomes, inpatient goals should include the shortest safe stay, prevention of both hyperglycemia and hypoglycemia, promote and preventing complications. Implementation of a clinical pharmacist in glycemic control of hospitalized, postoperative patients led to safer practice and better quality of glycemic care, and lower hypoglycemic episodes. According to the standards of medical care in Diabetes—2021, Collaborative, multidisciplinary teams are the best practice to provide care for people with chronic conditions such as diabetes to facilitate adherence and patients’ self-management ( American Diabetes Association, 2019) ( Mularski, 2012 ) ( American Diabetes Association,2021) (Butt,2016) ( Warrington,2012). The results of our study are most similar to a study by Abuloha S. (2016); and Katherine Fukunaga, 2020 which showed that a clinical pharmacist has a role in monitoring diabetic patients and decreasing HbAC however their study focused on the role of clinical pharmacist in Insulin management in an out-patient setting. (Abuloha,2016) ( Fukunaga, 2020) (Hughes ,2017) (Alsuwayni,2020)
In our study, HbAC , and FBG were significantly reduced with pharmacists’ interventions compared with usual care. In our study the patients did not get the therapeutic target of HbAC and FBG, patients were followed for six months but with time clinical pharmacists' interventions would help patients meet the target of their treatment.
Limitation of the study :
Our study is open study design (not blinded). Performance bias in both groups was likely in this study.
