Long-term evolution of renal function in patients with type 2 diabetes mellitus: a registry-based retrospective cohort study

Objectives To picture the 10-year evolution of renal function in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) and to describe the risk factors for severe decline. Setting Primary registration network with 97 general practitioners working in 55 practices sending routinely collected patient data. Participants From the database, we selected all patients aged 40 years or older with T2DM and at least two creatinine measurements in two different years with an interval of at least 3 months. Based on the last available value of estimated glomerular filtration rate calculated by the modification of diet in renal disease (MDRD) equation, patients were divided into grades of CKD. Severe decline (decline of >4 mL/min/year) and ‘certain drop’ (CD, year-to-year decline >10 mL/min) were determined in patients with CKD. Determinants of severe decline and CD were investigated with logistic regression and longitudinal logistic regression analysis, respectively. Primary outcome measure Kidney function (MDRD). Results 4041 patients, 1980 women, were included. The mean age was 71 years, mean diabetes duration was 7.7 years; 1514 (38%) suffered from CKD, 231 (15%) presented with severe decline and 18% of the patients with CKD presented with two or more CDs. Younger age, male gender, mean glycated haemoglobin and a higher number of CDs were significantly associated with the presence of severe decline (p<0.05); statins and higher diastolic blood pressure were significantly associated with the absence of severe decline (p<0.001). ACE inhibitors, other antihypertensive drugs and antidiabetic drugs including insulin therapy were specific determinants of CD. Conclusions CKD is highly prevalent in patients with T2DM; a minority of patients evolve into severe decline that is associated with younger age, male gender, ‘CD’ and manageable factors such as blood pressure, blood glucose, associated drugs prescriptions and statin therapy. Further prospective observational and experimental research is needed to clarify the nature of those associations.

Setting up a common architecture for EPR in primary care: the Belgian experience.

A couple of years ago, the Belgian Federal Ministry of Health decided to back the development of a basic conceptual model for Electronic Patient Record (EPR) in primary care. Using consensus and modeling relational techniques, a working group of experts and experienced practitioners identified 7 key structuring concepts: Health Care Element, Health Approach, Contact, Subcontact, Service, Health Agent, Period. This model could roughly be seen as a restrictive sub-model of the current CEN proposal (prENV 13940) or as a first step to assess this CEN pre-Norm in Belgium. The conceptual model is already used in teaching activities and in a Belgian software labeling process.

Purposes of health identification cards and role of a secure access platform (Be-Health) in Belgium

Although other alternatives may exist, identification cards have been chosen as an acceptable and adequate tool to be used to identify patients and health professionals. It is planned to use these for digital signature and for access to electronic health records: for searching various databases as well as for health information exchange. Local applications might exist independently, but the Belgian federal state has now developed Be-Health, a platform for health professionals, social security personnel and the general public, designed to facilitate a secure common uniform access to certain health data.

The use of a compliant EHR when providing clinical pathway driven care to a subset of diabetic patients: recommendation from a Working Group.

The Belgian National Health Insurance Institute (NHII) and other Healthcare Authorities intend to improve the quality of care through promoting clinical pathway driven care and by optimising cooperation between the responsible primary care physician and the diabetologist. Patients and healthcare professionals are granted some (financial) benefits when meeting the conditions defined in a mutual agreement.This article describes the conditions and the functional requirements to be met by an EHR to enable and to maximise the benefits of a clinical pathway driven patient care to a specific group of diabetic type 2 patients, based on a mandate issued by the NHII.The generic and specific functional requirements are then translated in test criteria for certification and prioritised in an implementation plan.

What determines inclusion in the early phase of the type 2 diabetes care trajectory in Belgium

BackgroundIn 2009, the Belgian National Institute of Health and Disability Insurance established a care trajectory (CT) for a subgroup of type 2 diabetes mellitus patients (T2DM) based on Wagner’s chronic care model. The goal of this CT is to optimise the quality of care using an integrated multidisciplinary approach. This study aims to identify patient-related factors associated with inclusion in a CT and to determine the most frequent reasons for non-inclusion.MethodsIn 2010, the Belgian Sentinel Network of General Practices conducted a prevalence study of type 2 diabetes. The surveillance study carried out by this nationwide, representative network collected unique information about eligibility for the CT, inclusion in the CT and reasons for non-inclusion.Based on the official inclusion and exclusion criteria, we first identified a group of eligible patients. Within this group, we then calculated the proportion of patients included in a CT as well as the prevalence of reasons for non-inclusion as reported by GPs. Furthermore, bivariate associations between patient-level parameters and inclusion were analysed. Finally, any patient-level parameters found to be statistically significant were included in a multivariate logistic regression model.ResultsThe 2010 study recorded 4600 Belgian type 2 diabetes patients. According to the official criteria, 589 patients were eligible for inclusion in a CT T2DM. By the end of August 2011, 95 patients had been included in a CT T2DM.Our findings reveal that the younger the eligible patient was, the more likely he or she was to be included in a CT. Patients living in Flanders were more likely to be included in the CT than were patients living in Wallonia. Motivated patients with specific plans to change their diets were also more likely to be included in a CT.The two most frequently reported reasons for non-inclusion were participation in another diabetes care programme and the timing of this surveillance study (inclusion will take place in the near future).ConclusionsEligible diabetes patients who were admitted to a CT T2DM during the early phases of CT implementation were mainly found to be those who are able to make progress in their disease trajectories. In the future, more attention could be paid to also include more high-risk patients.
