Impact of a chronic care model based on patient empowerment on the management of Type 2 diabetes: effects of the SINERGIA programme.

AIMS: Several chronic care models for diabetes have been implemented in Italy, although conclusive data on their effectiveness are lacking. In the Cusano-Milanino diabetes clinic, patients with Type 2 diabetes with a stable disease/therapy (i.e. a steady level of HbA(1c) without need for therapy changes) are included in the SINERGIA programme: diabetologists, nurses and dietitians empower patients and telemedicine resources are utilized efficiently. METHODS: Clinical outcomes measured in the year before and after the initiation of SINERGIA were compared. A generalized hierarchical linear regression model for repeated measures was used. RESULTS: Altogether, 1004 patients were included; baseline characteristics were (mean ± sd): age 66.6 ± 6.2 years, 54.1% male, diabetes duration 10.8 ± 7.7 years, BMI 29.5 ± 4.8 kg/m(2) , HbA(1c) 6.9 ± 0.9% (52 ± 14 mmol/mol); 72.9% of patients were treated with anti-hypertensive drugs; 32.7% were treated with lipid-lowering drugs. After a median follow-up of 12 months (range 6-24 months), the proportion of patients with HbA(1c) ≤ 7.0% (≤ 53 mmol/mol) increased from 32.7 to 45.8% (P<0.0001), while those with HbA(1c) ≥9% (≥75 mmol/mol) decreased from 10.5 to 4.3% (P<0.0001). Patients with LDL cholesterol <100 mg/dl (<2.59 mmol/l) increased from 40 to 47% (P <0.0001), while those with LDL cholesterol ≥130 mg/dl (≥3.36 mmol/l) decreased from 26.6 to 19.7%; blood pressure levels were slightly improved. The mean number of face-to-face encounters decreased from (median and range) 2.8 (2.3-3.4) to 2.3 (1.9-2.7) (P<0.0001) visits per patient/year. CONCLUSIONS: The SINERGIA model is effective in improving metabolic control and major cardiovascular risk factors, while allowing diabetologists to dedicate more time to patients with more acute disease.

Clinical and socio-economic correlates of quality of life and treatment satisfaction in patients with type 2 diabetes.

BACKGROUND AND AIM: The aim of the present study was to assess health-related quality of life (HRQOL) and treatment satisfaction in a large, ambulatory based sample of patients with type 2 diabetes. In particular, we evaluated a large array of socio-economic, clinical, and management-related factors, to investigate the extent to which they correlate with physical and psychological well-being, and with treatment satisfaction. METHODS AND RESULTS: Patients were requested to fill in a questionnaire including the SF-36 Health Survey (SF-36), the WHO-Well Being Questionnaire (WBQ), and the WHO-Diabetes Treatment Satisfaction Questionnaire (DTSQ). The analyses were based on multivariate analyses, adjusted for patient clinical and socio-demographic characteristics. The study involved 2499 patients, enrolled in 203 diabetes outpatient clinics. Female gender and diabetes complications were associated with worse physical and psychological well-being, while socioeconomic variables were mainly related to general well-being. The perceived frequency of hyperglycemic episodes was negatively associated with all the dimensions explored. Treatment satisfaction was inversely related to female gender, insulin treatment, perceived frequency of hyperglycemic episodes and diabetes complications. Blood glucose self-monitoring, and among patients treated with insulin, self-management of insulin doses and the use of pen for insulin injections, were associated with higher levels of satisfaction. Finally, higher levels of satisfaction were associated with a better perception of physical and psychological well-being. CONCLUSIONS: Health related quality of life and treatment satisfaction are associated with each other and are both affected by a complex interplay between clinical and socio-economic variables. Some negative aspects, mainly associated with insulin treatment and poor perceived metabolic control, can be attenuated by a deeper involvement of the patients in the management of the disease.

[Early therapeutic education in chronic renal disease: a new approach]. / La presa in carico precoce nell'insufficienza renale cronica: un nuovo approccio.

Chronic renal failure (CRF) remains a significant problem. Early referral of patients reduces cardiovascular risk and allows better quality of life and life expectancy. Uremic patients represent a typical example of chronic disease, which requires multidisciplinary team involvement and stratification of treatment processes. During the evolution of the disease to chronicity, the patient requires different clinical approaches that form part of a unique treatment process, involving day-to-day management, carried out by the general practitioner, as well as the handling of acute events requiring specialized clinical management. Early referral essentially requires three steps. The first step is therapeutic education, which includes information, sensitiveness, training and acceptance of the disease. The second step is the assembling of a multidisciplinary team in which the members are able to work together, coordinating and managing treatment protocols. These two steps allow the design of the third step, disease management, which consists of a methodology based on an integrated approach to the dis-ease allowing continuous improvement in medical care, in the patient's quality of life and a better use of economic resources.

Abnormal response to exercise in middle-aged NIDDM patients with and without autonomic neuropathy.

The cardiovascular response to exercise in middle-aged non-insulin-dependent diabetes mellitus (NIDDM) patients and the potential role of clinical characteristics and autonomic function were evaluated. One hundred and eight NIDDM patients, aged 40-65 years, were compared with a control group of 112 subjects, matched by age, sex, physical fitness, and presence of hypertension. All subjects performed a maximal exercise test. The diabetic patients completed cardiovascular autonomic neuropathy (CAN) tests: deep breathing, postural hypotension and lying to standing. There were no significant differences in total work capacity, heart rate, and blood pressure, either at rest or at peak exercise between the two groups. Diabetic patients showed significantly lower values of systolic and diastolic blood pressure during exercise, significantly slower recovery of heart rate (at 5th minute the average values were 102.7 +/- 14.1 beats min-1 vs 91.9 +/- 11.1, p < 0.001); and significantly higher proportion of blunted increase of heart rate (9.2% vs 0.9%, p < 0.001) and systolic blood pressure (9.2% vs 0.7%, p < 0.001) during exercise. No correlation between the exercise results and the main clinical characteristic (presence of hypertension, BMI, duration of diabetes, treatment, microalbuminuria, total score of CAN) was observed. These findings suggest that the cardiovascular response to exercise could be impaired also in the absence of signs of CAN. This impairment was higher in patients showing a dysfunction of orthosympathetic activity.
