Abstract
OBJECTIVE Several studies evaluated inpatient diabetes teaching and treatment programmes (DTTP) in diabetes type 1 (DM1) many years ago, but in these studies insulin treatment was not yet intensified before the DTTP. Today, most patients are already on intensified insulin treatment before entering a DTTP. The aim of this trial was to evaluate the outcome one year after participation in an inpatient intervention including a DTTP in a longitudinal study. METHODS 109 patients participated in an inpatient intervention in 2014. All individuals were invited to participate in an outpatient follow-up visit after one year. RESULTS Ninety participants (52.2% female, age 48.0 y, diabetes duration 19.1 y, 31.1% CSII, HbA1c 7.9% / 63.3 mmol/mol) were followed-up after 1.2±0.3 y [1 died, 18 declined / were not available]. 83 / 90 individuals participated to optimise diabetes therapy, 7 / 90 had newly-diagnosed DM1. In the optimisation group, HbA1c decreased by 0.4% (p=0.009) without change of insulin dose (54 IU/day before and after) or BMI (26 kg/m2 before and after). In people with baseline HbA1c ≥7.5% (n=26 / 83), HbA1c decreased by 0.9%. The frequency of severe hypoglycaemia decreased from 0.22 to 0.05 events / year (p=0.045). In people with frequent non severe hypoglycaemia (n=8), events decreased from 4.5±2.0 to 2.8±0.9 / week (p=0.358). Systolic (-6.5 mmHg, p=0.035) and diastolic (-3.4 mmHg, p=0.003) blood pressure improved without change of number of antihypertensive medication (1.9±2.1 vs. 1.8±2.0, p=0.288). CONCLUSIONS In people with DM1, metabolic control improved after the inpatient intervention without increasing insulin dosage or BMI. The inpatient intervention remains effective to substantially improve metabolic control under the present circumstances of care.

Abstract
PURPOSE The cardiovascular diseases (CVD) are the leading cause of mortality in type 1 diabetes (DM1). Carotid intima-media thickness (IMT) has been approved as a marker of subclinical atherosclerosis. The aim of this prospective study was to evaluate the relationship between baseline diabetic knowledge after five-day teaching program and IMT in patients with (DM1) treated with intensive functional insulin therapy (IFIT) from the onset of the disease. MATERIAL/METHODS The analysis included 79 subjects aged 23.4 ± 5.1 years with newly diagnosed DM1, participating in Poznan Prospective Study (PoProStu). The patients attended a five-day structured training program in IFIT at diagnosis, followed by a test consisting of 20 questions. After follow-up period of 11 years we evaluated the presence of microangiopathy and subclinical macroangiopathy. IMT of the right common carotid artery was determined using high resolution ultrasonography and calculated automatically with the Carotid Analyzer for Research program. RESULTS After 11-year follow-up median intima-media thickness was 560 (IQR: 520-630) μm. We found a negative correlation between diabetes knowledge at baseline and IMT at the end of follow-up (r=-0.27, p=0.017). In multivariate linear regression model baseline diabetic knowledge test result was associated with IMT at follow-up, independently from sex, age, smoking status, presence of hypertension and diabetic kidney disease (all at follow-up) and from mean follow-up LDL-cholesterol concentrations and HbA1c results (β=-8, 95% CI -16, -1, p=0.037). CONCLUSIONS Baseline diabetic knowledge after 5-day teaching program is an independent predictor of subclinical macroangiopathy in patients with DM1.

Abstract
OBJECTIVE Evaluation of an ambulatory diabetes teaching and treatment refresher programme (DTTP) for the optimization of intensified insulin therapy in patients with type 1 diabetes (refresher course). METHODS 85 outpatients took part in this prospective multicentre trial. Metabolic and psychosocial data were analyzed at baseline (V1), 6 weeks (V2) and 12 months after DTTP (V3). RESULTS In patients with baseline HbA1c>7% (88%), HbA1c decreased by 0.36% (p=0.004). The percentage of patients with HbA1c≤7% increased from 21.3 to 34.9% and with HbA1c above 10% decreased from 6.6 to 1.6% at V3. The incidence of hypoglycaemia decreased significantly: non severe hypoglycaemia from 3.31 to 1.39 episodes/pat/week (p=0.001) and severe hypoglycaemia from 0.16 to 0.03 episodes/pat/year (p=0.02). The treatment satisfaction increased by +10 of maximal ±18 points. The negative influence of diabetes on quality of life decreased from -1.93 to -1.69 points (p=0.031). CONCLUSION In a group of patients with moderately controlled diabetes type 1 who were already treated with intensified insulin therapy, metabolic control, treatment satisfaction and quality of life were improved after participation in an ambulatory DTTP without increasing insulin dosage, number of injections or insulin species. PRACTICE IMPLICATIONS This DTTP is effective for the optimization of intensified insulin therapy.

Abstract
Dose adjustment for normal eating (DAFNE) is a well-established structured education programme for patients with type 1 diabetes. We conducted a retrospective analysis of insulin dose changes associated with DAFNE training. Our results show significant reductions in total, quick acting and basal insulin doses in patients undergoing DAFNE training.

Abstract
BACKGROUND To investigate the characteristics of people with insulin-treated diabetes, who have experienced severe hypoglycaemic events (SHEs), in Germany, Spain or UK. METHODS Patients with type 1 (n=319) or insulin-treated type 2 diabetes (n=320) who had experienced ≥ 1 SHE in the preceding year were enrolled. Their median age was 53 years (range, 16-94 years). Data were collected using a questionnaire administered by an experienced interviewer. RESULTS The median number of reported SHEs was 2-3 in 12 months. Most events (69%) occurred at home, usually during the day or evening (74%) and most commonly due to insufficient food consumption (45%). In patients whose hypoglycaemia awareness was tested, 68% had normal awareness. Patients requiring emergency healthcare treatment frequently had impaired hypoglycaemia awareness, and developed hypoglycaemic coma more often. Hospital treatment was usually provided in an emergency department (72-94%). The duration of stay was longest in Germany. Following a SHE, patients receiving professional treatment were more likely to: consult their physician, test their blood glucose more often, adjust insulin dose and receive self-management training. CONCLUSIONS This survey of diabetes patients aged 16-94 years showed that SHEs represent a substantial burden on national healthcare systems in Germany, UK and Spain. The pattern of occurrence and treatment was similar in all three countries, despite differences in cultures and healthcare systems.

Abstract
AIMS To assess the outcome of a Diabetes Treatment and Teaching Programme (DTTP) on glycated haemoglobin (HbA1c), severe hypoglycaemia (SH) and severe ketoacidosis (SKA) in adolescents and young adults with Type 1 diabetes. METHODS Quality-assurance project with assessment of participants 1 year after participation in a DTTP (5-day inpatient course, groups < or = 10 patients, fixed curriculum of education/training, introduction of dietary freedom). Before-after analyses of participants aged 12-15, 15-18, 18-21 and 21-24 years. Main outcome measures were HbA1c, SH and SKA. RESULTS For the 1592 participants, aged 12 to 24 years, mean age at enrolment was 19 +/- 3 years, mean duration of diabetes was 7.3 +/- 5.4 (range 0.3-24) years, mean baseline HbA1c declined from 8.8 +/- 2.3% to 8.1 +/- 2.0%. The incidence of SH was 0.31 vs. 0.11 events/patient/year; the incidence of SKA 0.17 vs. 0.07 events/patient/year. In mixed effects models taking into account effects of centres, age and diabetes duration, the mean difference was -0.64%[P < 0.001, 95% confidence interval (CI) -0.79 to -0.5] for HbA1c, -0.2 events/patient/year (P < 0.0001, 95% CI -0.28 to -0.12) for SH and -0.1 events/patient/year (P < 0.0001, 95% CI -0.14 to -0.06) for SKA. CONCLUSIONS Adolescents and young adults with Type 1 diabetes benefit from participation in a standard DTTP for flexible, intensive insulin therapy and dietary freedom.

Abstract
Common methodologies used in systematic reviews do not allow adequate appraisal of complex interventions. The aim of the present study was to describe and critically appraise current methods of systematic reviews on complex interventions, using diabetes and hypertension patient education as examples. PubMed, the Cumulative Index to Nursing and Allied Health (CINAHL), the Cochrane Library and Health Technology Assessment databases were searched. Systematic reviews focusing on diabetes or hypertension patient education were included. Authors were contacted. Two investigators independently evaluated the reviews. The available evidence of three patient education programmes of diabetes and hypertension self-management implemented in Germany was used as a reference. We included 14 reviews; 12 reviews mentioned that the included education programmes were multidimensional. Reviews on comparable topics identified different publications of the same programme. Identical programmes were classified differently within and between reviews. Education programmes were dissected to analyse effects of single components. Different components of identical programmes were used. Interdependencies between components were not explored. Six reviews performed meta-analysis across programmes with heterogeneous educational or organisational approaches. The complexity of efficacy measures was disregarded: e.g. HbA(1c) was used as an isolated outcome variable without considering treatment goals, effects on hypoglycaemia, body weight or quality of life. Our results indicate that methods of current systematic reviews are not fully equipped to appraise patient education and self-management programmes. Since these are complex and heterogeneous interventions, consideration of aggregated evidence is necessary.

Abstract
OBJECTIVE Diabetes treatment and teaching programs (DTTPs) for type 1 diabetes, which teach flexible intensive insulin therapy to enable dietary freedom, have proven to be safe and effective in routine care. This study evaluates DTTP outcomes in patients at high risk for severe hypoglycemia and severe ketoacidosis. RESEARCH DESIGN AND METHODS There were 96 diabetes centers that participated between 1992 and 2004. A total of 9,583 routine-care patients with type 1 diabetes were examined before and 1 year after a DTTP. History of repeated severe hypoglycemia/severe ketoacidosis was an indication for DTTP participation. Before-after analyses were performed for subgroups of patients with three or more episodes of severe hypoglycemia or two or more episodes of severe ketoacidosis during the year before a DTTP. Main outcome measures were GHb, severe hypoglycemia, severe ketoacidosis, and hospitalization. RESULTS A total of 341 participants had three or more episodes of severe hypoglycemia the year before a DTTP. Mean baseline GHb was 7.4 vs. 7.2% after the DTTP, incidence of severe hypoglycemia was 6.1 vs. 1.4 events x patient(-1) x year(-1), and hospitalization was 8.6 vs. 3.9 days x patient(-1) x year(-1). In mixed-effects models taking effects of centers and diabetes duration into account, mean difference was -0.3% (95% CI -0.5 to -0.1%; P = 0.0006) for GHb and -4.7 events x patient(-1) x year(-1) (-5.4 to -4; P < 0.0001) for severe hypoglycemia. A total of 95 patients had two or more episodes of severe ketoacidosis. GHb was 9.4% at baseline versus 8.7% after DTTP; incidence of severe ketoacidosis was 3.3 vs. 0.6 events x patient(-1) x year(-1), and hospitalization was 19.4 vs. 10.2 days x patient(-1) x year(-1). In linear models with diabetes duration as the fixed effect, the adjusted mean difference was -2.7 events x patient(-1) x year(-1) (95% CI -3.3 to -2.1; P < 0.0001) for severe ketoacidosis and -8.1 days (-12.9 to -3.2; P = 0.0014) for hospitalization. CONCLUSIONS Patients at high risk for severe hypoglycemia or severe ketoacidosis may benefit from participation in a standard DTTP for intensive insulin therapy and dietary freedom.

Abstract
OBJECTIVES We examined time trends of hospitalization, a main outcome measure in health care, in the diabetic and nondiabetic populations in Germany and their associations with sociodemographic variables. METHODS Using data from 2 national health surveys, we estimated hospital days per person-year in the diabetic and nondiabetic populations in 1998 (n=5422) and 1990-1992 (n=7363) in Germany. We used Poisson regression to estimate relative risks and interaction of secular time with age, gender, and educational level, considering the cluster sample design of the study. RESULTS Hospital days per person-year decreased between 1990-1992 and 1998--from 3.59 (95% confidence interval [CI]=2.59, 4.97) to 3.14 (95% CI=2.16, 4.56) for the diabetic population and from 1.38 (95% CI=1.23, 1.55) to 1.33 (95% CI=1.17, 1.51) for the nondiabetic population--but the decrease was not statistically significant. In the diabetic population, the decrease tended to be more pronounced (interaction year x time not significant; P=.756). Also, there was a notable decrease in men and in the group aged 25 to 39 years, and a decrease in both high- and low-educational-level subjects. CONCLUSIONS There seems to have been a larger decrease in hospitalization in the diabetic population than in the nondiabetic population in Germany. An increase in social disparity in this health outcome measure in the diabetic population could not be confirmed.

Abstract
Intensive insulin treatment is defined by basal-prandial insulin therapy which tries to reproduce physiological insulin secretion. This requires 3 to 5 injections and self-monitoring of blood glucose 4 to 5 times a day. Patients who accept their disease and the demanding treatment regimen most often achieve HbA1(c) < 7.5%. Severe complications of diabetes can be avoided without increasing the risk of severe hypoglycemia. However, 50% of type 1 diabetic patients do not reach this objective. The reasons are: the disease itself, the diabetic patient, or the physician. Brittle diabetes with severe, repeated episodes of hypoglycemia and inversely persistent postprandial hyperglycemia prevents patients from reaching the ideal glycemic target. More often, the main obstacle is related to psychological problems: difficulties in self-regulation, denial of the disease, or phobia of hypoglycemia with avoidance behavior. Frequently, young women present eating disorders which can explain the poor diabetes control. The physician himself may be implicated in these poor glycemic results by not prescribing the right tools to obtain optimal glycemic control (staying with just two daily injections with premixed insulin) or by assigning glycemic targets inaccessible for the patient, or when an empathic relationship cannot be established between the patient and the physician. Patient empowerment is the key to the success of functional insulin treatment.

Abstract
AIMS/HYPOTHESIS The aim of this study was to evaluate the implementation of a course teaching flexible, intensive insulin therapy on glycaemic control and severe hypoglycaemia in routine care. METHODS This is a continuous quality-assurance project involving hospital diabetes centres. Every third year each centre re-examines 50 consecutive patients (evaluation sample) 1 year after participation in the course. Ninety-six diabetes centres in Germany participated and 9,583 patients with type 1 diabetes (190 evaluation samples) were re-examined between 1992 and 2004. The intervention was a 5-day inpatient course for groups of up to ten patients with a fixed curriculum of education and training for dietary flexibility and insulin adjustment. The main outcome measures were HbA1c and severe hypoglycaemia. RESULTS Mean baseline HbA1c was 8.1%, and had decreased to 7.3% at follow-up; incidence of severe hypoglycaemia was 0.37 events per patient per year prior to intervention and 0.14 after intervention. In mixed-effects models adjusted for effects of centres, age and diabetes duration, the mean difference was -0.7% (95% CI -0.9 to -0.6%, p<0.0001) for HbA1c and -0.21 events per patient per year (95% CI -0.32 to -0.11, p=0.0001) for severe hypoglycaemia, with similar results for evaluation samples, with a maximum of 10% of patients lost to follow-up. Before intervention, the incidence of severe hypoglycaemia was three-fold higher in the lowest quartile than in the highest quartile of HbA1c, whereas the risk was comparable across the range of HbA1c values after intervention. CONCLUSIONS/INTERPRETATION Implemented as part of a continuous quality-assurance programme the self-management programme is effective and safe in routine care. Improvement of glycaemic control can be achieved without increasing the risk of severe hypoglycaemia.

Abstract
During the last quarter of a century continuous subcutaneous insulin infusion (CSII) with external portable insulin pumps has been increasingly used in selected type 1 diabetic subjects and also in some patients with type 2 diabetes mellitus. The treatment of diabetes mellitus with insulin pumps has become more and more popular and accepted by diabetic patients as well as by medical professionals worldwide. Published trials have shown that, in most patients, mean blood glucose concentration and glycated hemoglobin (HbA1c) percentages are either slightly lower or similar on CSII versus an optimized therapy with multiple daily insulin injections. Hypoglycemic episodes seem to be less frequent and ketoacidoses occur at a comparable rate to that during intensive injection therapy. Moreover, nocturnal glycemic control can be improved with insulin pumps, and automatic basal rate changes help to minimize a prebreakfast blood glucose increase (often called 'the dawn phenomenon'). For many patients, CSII provides greater flexibility in timing of meals with the result of better quality of life and higher treatment satisfaction. However, despite these promising data, and although many patients with diabetes mellitus with well-defined clinical problems are likely to benefit substantially from CSII, either in respect to glycemic control, acute complications or quality of life and treatment satisfaction, we are still far away from reaching'dream diabetes management', the fully automatic closed-loop system. Presently, the most difficult problem concerns not the design of an 'optimal' insulin pump, but rather the development of a system which is able to provide continuous and reliable blood glucose monitoring. Hence, because this problem has not been solved with maximum satisfaction, the development of a feedback-controlled 'artificial pancreas' is one of the main goals in diabetes management in the new millennium.

OBJECTIVES To assess the effect of a particular insulin regimen called "functional insulin therapy" using a short-acting insulin analog on the risk of severe hypoglycemia and the HbA(1c) level among patients already under intensive insulin therapy. DESIGN A cohort of 110 patients with type 1 diabetes receiving intensive insulin therapy with regular insulin for several years was followed during one year after initiation of functional insulin therapy (FIT) with a short-acting insulin analog. The glycemic control was assessed by the mean value of the last three HbA(1c) assays before the initiation of FIT and then by the mean of the following three. The number of severe hypoglycemic episodes/patient/year during the year preceding and the year following the initiation of FIT was recorded. RESULTS The mean HbA(1c) level decreased on average by 0.7 percent during the 12-month study (p=0.0001) and the number of episodes of severe hypoglycemia fell to 75% of its previous level (p<0.05). CONCLUSION Substitution of intensive insulin therapy using regular insulin for functional insulin therapy using short-acting insulin analog may improve glycemic control and reduce the risk of severe hypoglycemia.

Abstract
Hypoglycemia is the most feared side effect of diabetes therapy with blood glucose-lowering agents. The fear of hypoglycemia often contributes to poor metabolic control of patients with diabetes. Therefore, integration of a hypoglycemia warning signal into continuous glucose monitoring systems represents an important additional help for patients with diabetes. The warning signal can be triggered at a preset level based on the current glucose values (as provided with the presently available glucose monitoring systems) or on prospective trend analysis offering the possibility to predict the risk of a hypoglycemic event in an anticipatory manner. Using the approach of a "Finite State Machine," such a more advanced warning system can completely be described as a finite collection of four states and possible transitions in-between. Most of the currently available glucose monitoring systems measure glucose in the interstitial fluid (ISF) of the dermal or subcutaneous tissue but are calibrated to blood glucose levels. This requires a number of factors to be taken into account: precision and accuracy of the glucose measurements, physiological and physical lag time, and calibration of the glucose monitoring system. From our point of view, the analytical performance of the system should be such that the majority of all hypoglycemic episodes are correctly diagnosed (>75%). Inconsistent findings regarding physiological discrepancies between blood and ISF glucose, which usually are described as a physiological lag time, range from some seconds up to 15 min. They can be observed especially during dynamic blood glucose changes (>3 mg/dL/min) and may represent major challenges for the development of a reliable hypoglycemia warning signal. In addition to possible physiological time lags, device-inherent physical lag times must be considered when selecting the threshold for the warning signal. Despite these problems, most probably all patients with diabetes who are treated with blood glucose-lowering agents will benefit from such a system since their safety and quality of life can be greatly improved, including an optimized metabolic control and lowered diabetes-related mortality. The benefit will be greatest for patients with hypoglycemia unawareness or impaired perception of hypoglycemic symptoms. The risks related to the use of a hypoglycemia warning signal seem to be low if certain precautionary measures are taken. In any case, additional clinical-experimental studies in healthy subjects as well as long-term clinical studies in diabetic patients are necessary to further evaluate the efficacy, benefits, and risks of different hypoglycemia warning concepts implemented in the different continuous glucose monitoring systems.

Abstract
AIMS Data concerning the relative risk of amputations in diabetic patients compared with the general population are scarce. Therefore, we carried out a case control study to quantify the relationship between diabetes and amputations. METHODS In 20 hospitals in seven German cities and counties we obtained complete lists of non-traumatic lower limb amputations performed in 1990 and 1991. CONTROLS were selected from patients of the same surgical departments operated on in the same years. We drew a random sample of patients with procedures not likely to be associated with diabetes. Diabetic status was determined from patients' records in both cases and controls. We calculated age- and sex-specific and, using logistic regression, adjusted odds ratios (OR) and attributable risks. RESULTS N = 2400, mean age 61.7 (SD 16.3) years. CASES n = 729; 486 (66.7%) of them had diabetes. CONTROLS n = 1671; 127 (7.6%) of them had diabetes. Adjusted OR: 18.2 (confidence interval (CI) 14.2-23.6). Adjusted attributable risk among exposed (ARE): 0.95 (CI 0.93-0.96). Adjusted population attributable risk (PAR): 0.62 (CI 0.57-0.66). CONCLUSIONS This study has demonstrated a strong association between the risk of amputation and diabetes. The odds ratios and attributable risks for diabetic individuals are higher in the younger than in the older age groups. Population attributable risks are great. We conclude that the reduction of amputations in the general population will be achieved by improving foot care in people with diabetes.

Abstract
AIM To investigate whether modular out-patient group education for flexible, Functional Insulin Treatment (FIT) adapted for pregnancy can eliminate diabetes-associated neonatal complications in pregestational diabetes. RESEARCH DESIGN AND METHODS Outcome analysis of the modular out-patient group education and FIT based on separate insulin dosages for fasting, eating or correcting hyperglycaemia in 76 consecutive pregnancies (in 20 cases first after conception) of 59 patients with pregestational diabetes (Type 1 diabetes, n = 54). CONTROLS (a) diabetic pregnancies: historical controls; (b) non-diabetic pregnancies: retrospective case-controlled study; (c) population-based data of all Austrian newborns registered within the respective time period. RESULTS HbA1c of 113 +/- 18% of mean value (= 100%) of non-diabetic, non-pregnant population (103 +/- 14% during the last pregnancy trimester), and self-monitored blood glucose of 5.6 +/- 0.7 mmol/l (5.3 +/- 0.7 mmol/l during the last trimester) was achieved throughout all FIT pregnancies. Severe hypoglycaemia occurred in 14 pregnancies. The gestational age at delivery was 39.2 +/- 1.5 weeks (four cases (5.4%) < 37 weeks) with a birth weight of 3305 +/- 496 g. Four newborns (5.3%) were above the 90th, and nine (11.8%) below the 10th percentile for weight of reference population-based data. Hypoglycaemia was recorded in six newborns (8%). Malformations were found in two infants whose mothers booked for diabetes FIT education only after conception. The caesarean delivery rate was 25%. In comparison with historical diabetic pregnancy controls we demonstrated a reduction in major complications, and compared with non-diabetic women, a lowering of diabetes-related neonatal complication rates to general population levels. CONCLUSIONS Structured, comprehensive, modular out-patient group education promoting self-choice of insulin dose for flexible, normal eating prior to conception normalizes pregnancy outcome in diabetes.

Abstract
PURPOSE The study was performed to test the effect of a structured intervention in diabetic patients with poor glycaemic control in an ophthalmological department. PATIENTS AND METHODS All the patients attending the ophthalmological out-patient department with the need for laser therapy due to diabetic retinopathy were investigated from January to March 1998 (Type 1: n=20, Type 2: n=144). If an HbA(1c)-level higher than 9.0% was found the patient was informed within 1 week and a standardised letter was sent to the primary care physician and the local ophthalmologist. Over the first 3 months of 1999 the effect was evaluated. RESULTS HbA(1c) values higher than 9.0% were found in eight/20 of the patients (40%) with Type 1 diabetes and in 61/144 of the patients (54%) with Type 2 diabetes. In 55% this new information in the context of the need for laser therapy resulted in the acceptance of a structured intervention by the patient. This led to an improvement of the HbA(1c) in the people with Type 1 diabetes. CONCLUSION Patients with poor blood glucose control can be identified in an ophthalmological department. The need for laser therapy can be used to motivate the patients for a significant improvement of the quality of blood glucose control.

Abstract
Several changes in health politics and legal settings in recent years have affected the structure and practice of health promotion and patient education in Germany. The current legal background and its implications for patient education are discussed. Based on examples from four selected areas (cardiovascular diseases, diabetes mellitus, chronic pain, and asthma) the current practice of patient education in Germany is summarized. While many well-structured programs exist that are based on state-of-the-art guidelines, there is a lack of high quality research that documents the long-term effectiveness and cost-effectiveness of such approaches. Structural problems and an insufficient number of highly trained personnel result in the fact that many patients do not have access to standardized programs. Persisting compliance problems indicate that there is still room for improvement of patient education interventions. As important for the future, necessary changes in the legal settings and possible implications for the education of the educators are discussed.

Abstract
OBJECTIVE To study the prognosis of persons with type 1 diabetes in relation to the degree of nephropathy at initiation of intensified insulin therapy. DESIGN Ten years follow-up of a cohort of 3674 patients who had participated in a 5-day group treatment and teaching programme for intensification of insulin therapy between September 1978 and December 1994. SETTING Ten diabetes centres in Germany. SUBJECTS A total of 3674 patients (insulin treatment before age 31), age at baseline 27 +/- 10 years, with a diabetes duration of 11 +/- 9 years. Patients were divided into three groups according to baseline renal parameters (group I, normal proteinuria, n = 1829; group II, microproteinuria, n = 1257; group III, at least macroproteinuria, n = 367). MAIN OUTCOME MEASURES End-stage diabetic complications (blindness, amputations, renal replacement therapy, standardized mortality ratios (SMR) and causes of death. RESULTS Outcome measures were documented for 97% of patients; 251 (7%) had died. During follow-up, 1% of patients in group I, 4% in group II and 47% in group III had at least one end-stage diabetic complication. SMR for men: nephropathy group I, 2.2 (95% CI = 1.5-3); group II, 3.2 (2.3-4.3); group III, 11.5 (8.8-14.7). SMR for women: group I, 2.5 (1.5-3.8); group II, 3.5 (2.2-5.3); group III, 27 (19.8-35.9). Causes of death for men and women combined: group I (total 58 deaths)--cardiovascular, 21 (36%); hypoglycaemia, 1; ketoacidosis, 3; violent deaths, 17 (29%); others, 16; group II (66 deaths)--cardiovascular, 25 (38%); hypoglycaemia, 2; ketoacidosis, 2; violent deaths, 14 (21%); others, 23; group III (114 deaths)--cardiovascular, 68 (60%); hypoglycaemia, 2; ketoacidosis, 5; infections, 15 (13%); violent deaths, 5 (4%); others, 19. CONCLUSIONS Patients with microproteinuria have only a slightly worse prognosis than patients with normal proteinuria during the first 10 years after initiation of intensified insulin therapy. Excess mortality amongst patients who started intensified insulin therapy is mainly due to those with manifest clinical nephropathy.

Abstract
AIMS To assess predictors of mortality and end-stage diabetic complications in patients with Type 1 diabetes mellitus on intensified insulin therapy. METHODS A cohort of 3,674 patients (insulin treatment before age 31) who had participated in a 5-day in-patient group treatment and teaching programme for intensification of insulin therapy between 9/1978 and 12/1994 were reassessed after 10 +/- 3 (mean +/- SD) years. RESULTS Vital status and data on blindness, amputations, and renal replacement therapy were documented for 97% patients; 7% patients had died, 1.3% had become blind, 2% had amputations and 4.6% started renal replacement therapy. Using the Cox proportional hazards model, the following risk factors of mortality as assessed at baseline were identified: nephropathy (at least macroproteinuria), hazard ratio 3.8 (95% confidence interval 2.6-5.6); smoking, 1.9 (1.4-2.6); diabetes duration, 1.5 (1.2-1.8) for a difference of 10 years; serum cholesterol, 1.1 (1.0-1.2) for a difference of 1 mmol/l; lower social status, 1.4 (1.1-1.8) for a difference of 1 out of 3 levels; age, 1.3 (1.1-1.6) for a difference of 10 years; male sex, 1.4 (1.1-1.9); systolic blood pressure, 1.1 (1-1.2) for a difference of 10 mmHg. For the combined endpoint - blindness or amputations or renal replacement therapy - predictors were: nephropathy, foot complications, HbA1c, smoking, cholesterol, systolic blood pressure, retinopathy, hypertension, and social status. CONCLUSION In Type 1 diabetic patients who start intensified insulin therapy, nephropathy remains the strongest predictor of mortality and end-stage complications. Glycosylated haemoglobin is a risk factor of end-stage complications but not of mortality. Conventional risk factors comparable to the general population, particularly smoking become operative as predictors of both mortality and end-stage complications.

Abstract
AIMS To evaluate a treatment and teaching programme including psychosocial modules for patients with Type 1 diabetes mellitus on intensified insulin therapy who failed to achieve their treatment goals despite participation in standard programmes. METHODS The 5-day inpatient programme comprises small groups of 4-6 patients, focusing on individual needs and problems. Beyond the teaching lessons (most topics are deliberately chosen by the patients), the programme provides intensive group discussions and offers individual counselling concerning motivational aspects, psychosocial problems and coping strategies. Of the first consecutive 83 participants, 76 were re-examined after 17.5 +/- 5.5 months (range 9-31 months). RESULTS At follow-up, HbA1c was not improved compared to baseline (8.0 +/- 1.3% vs. 8.1 +/- 1.5%). However, the incidence of severe hypoglycaemia per patient/year (glucose i.v., glucagon injection) was substantially decreased: 0.62 +/- 1.5 episodes at baseline compared to 0.16 +/- 0.9 at follow-up (P < 0.001). Twenty-six per cent of the patients at baseline, and 4% at re-examination had experienced at least one episode of severe hypoglycaemia during the preceding year (P < 0.001). Sick leave days per patient/year decreased from 17.0 +/- 38.5-7.7 +/- 13.6 days (P < 0.05). Patients improved their perceptions of self-efficacy, their relationship to doctors and felt less externally controlled (P < 0.001). The majority of patients perceived an improved competence regarding diet (80.6%) and adaptation of insulin dosage (82.4%), an improved knowledge (82.2%), and a renewed motivation for the treatment (84.5%). Treatment success was significantly associated with baseline HbA1c, stability of motivation, frequency of blood glucose self-monitoring, control beliefs and change in subsequent outpatient care. CONCLUSIONS The programme improved glycaemic control mainly as a result of a substantial reduction in the incidence of severe hypoglycaemia. Patients with persistent poor glycaemic control may benefit from structured follow-up care focusing on motivational aspects of self-management and psychosocial support.

Abstract
OBJECTIVE To describe the long-term simultaneous impacts of blood pressure and glycosylated haemoglobin values on the risk of progression of diabetic nephropathy. DESIGN Prospective, multicentre, 6-year follow-up study. SETTING One reference centre (university department of internal medicine) and nine general hospitals. SUBJECTS A total of 601 type 1 diabetic patients on intensive insulin therapy with and without diabetic nephropathy. MAIN OUTCOME MEASURES Progression of nephropathy was defined as change for the worse within five stages of nephropathy by at least one of these stages during the study period. By the use of logistic regression, the relationship between metabolic and blood pressure control and the risk of nephropathy progression was quantified. RESULTS The main determinants of nephropathy progression were glycosylated haemoglobin and blood pressure, which were both non-linearly associated with the risk of progression. No significant threshold levels for any of the predictors of progression were identified. CONCLUSIONS The results of this study underline the importance of optimizing metabolic and blood pressure control to arrest the progression of diabetic nephropathy without the evidence for a clinically relevant threshold effect.

Abstract
Structured diabetes teaching and treatment programmes (STTP) are increasingly offered for patients with diabetes to improve metabolic control. We prospectively studied the long term-effect of STTP on metabolic control and knowledge of diabetes in patients with type 2 diabetes. In addition, differences in the mode of follow-up by a university diabetes centre (UDC) versus general practitioner (GP) were assessed. Of the 64 patients with type 2 diabetes (61 +/- 10 years old, diabetes duration 11 +/- 7 years) included in the study 52 could be reevaluated after 2 years. Of those, 31 were followed up by the UDC and 21 by their GPs who received detailed follow-up instructions from the UDC. In all patients, HbA1c decreased from 9.1 +/- 0.3% before the programme to 8.3 +/- 0.3% 2 years after the programme (P = 0.004), whereas body mass index increased from 28.8 +/- 0.8 to 30.3 +/- 0.9 kg/m2 (P < 0.001). Patients had a significantly better knowledge of diabetes and diet 2 years after the programme. For all parameters tested, none of the changes differed between patients managed by the UDC versus those managed by their GP. However, patients who chose follow-up by the UDC were more obese and had a better knowledge of diabetes. In conclusion, the STTP for patients with type 2 diabetes was effective in improving the long-term glycaemic control and knowledge of diabetes. Moreover, with precise therapeutic goals and follow-up instructions given to patient and GP this improvement was independent of the mode of outpatient follow-up.

Abstract
Exercise is frequently recommended in the management of type 1 and 2 diabetes mellitus and can improve glucose uptake by increasing insulin sensitivity and lowering body adiposity. Both alone and when combined with diet and drug therapy, physical activity can result in improvements in glycaemic control in type 2 diabetes. In addition, exercise can also help to prevent the onset of type 2 diabetes, in particular in those at higher risk, and has an important role in reducing the significant worldwide burden of this type of diabetes. Recent studies have improved our understanding of the acute and long term physiological benefits of physical activity, although the precise duration, intensity, and type of exercise have yet to be fully elucidated. However, in type 1 diabetes, the expected improvements in glycaemic control with exercise have not been clearly established. Instead significant physical and psychological benefits of exercise can be achieved while careful education, screening, and planning allow the metabolic, microvascular, and macrovascular risks to be predicted and diminished.

Abstract
PATIENTS AND METHOD In a population based study the quality of diabetes care of insulin-treated diabetic patients aged 16 to 60 years and living in a rural area was studied. The parameters of metabolic control as well as the incidence of acute complications (severe hypoglycemia with the need of glucose or glucagon injection, ketoacidosis with hospital admission) were assessed by examination and with a standardized questionnaire in 81% of the target population (type-1/type-2-diabetic patients: n = 25/33). Also, in all the patients diabetic long-term complications (retinopathy, nephropathy, amputations of the lower extremities) were examined. 76% of the patients with type-1-diabetes and 91% of the patients with type-2-diabetes mellitus completed standardized questionnaires to assess quality of life and treatment satisfaction. RESULTS In type-1-diabetic patients HbA1c was 9.38 +/- 1.6%. In type-2-diabetic patients it was 9.53 +/- 1.91%. None of the patients examined was regularly treated by a specialized physician/diabetologist. The goal of metabolic control, a HbA1c value below 7.2%, was reached only by 4% of the patients with type-1-and 12% of the patients with type-2-diabetes mellitus. In multivariate analysis the most important factor associated with HbA1c was in type-1-diabetic patients female sex (R-squared = 0.17, c = 0.38, p = 0.059); in patients with type-2-diabetes mellitus it was the number of insulin injections per day (R-squared = 0.37, c = 0.19, p = 0.0096). All other factors investigated in the model (diabetes duration, insulin dosage/kg body weight, frequency of blood- or urine-glucose self-monitoring/week, body mass index, educational level) showed no significant associations. Quality of life and treatment satisfaction of the patients were good and comparable to other trials. CONCLUSION Out of other studies there is evidence for better metabolic control in patients regularly treated by specialized physicians/diabetologists and in patients who participated in structured treatment and teaching programs. These features must be the main goals of treatment for all patients with diabetes mellitus.

Abstract
Rapid-acting insulin analogues were developed in answer to the need for a more appropriate time-action profile for prandial insulin substitution therapy. Improvements in at least one of three important endpoints needs to be demonstrated-metabolic control, hypoglycemic events, and/or quality of life-if there is to be a case for use of a new insulin preparation. This paper considers the data available on hypoglycemic events in the 24 controlled clinical trials (19 open, unblinded, and 5 double-blind) reported to date with rapid-acting insulin analogues (22 studies with insulin lispro). A significant reduction in the incidence of mild hypoglycemia was observed in 5 of 22 studies (22%). No change in frequency of severe hypoglycemic episodes was observed 10 of 12 studies (83%) reporting such events. A decrease in the frequency of nocturnal hypoglycemia has been reported in six studies; however, in the other 18 studies, no similar decrease in numbers were reported. There is no evidence for a reduction in patient awareness of hypoglycemia with rapid-acting insulin analogues. Even a slight reduction in hypoglycemic events would be welcomed by diabetic patients. However, rapid-acting insulins are only appropriate for use in patients using an intensive insulin regimen. Such patients are well motivated and well educated and will be able to adapt their insulin therapy to take account of the changes in the time-action profile of the rapid-acting insulin analogues. Thus, rapid-acting insulin analogues do not appear to have revolutionized insulin therapy, but appropriate use should result in benefits such as improved metabolic control for diabetic patients.

Abstract
The proportional odds model (POM) is the most popular logistic regression model for analyzing ordinal response variables. However, violation of the main model assumption can lead to invalid results. This is demonstrated by application of this method to data of a study investigating the effect of smoking on diabetic retinopathy. Since the proportional odds assumption is not fulfilled, separate binary logistic regression models are used for dichotomized response variables based upon cumulative probabilities. This approach is compared with polytomous logistic regression and the partial proportional odds model. The separate binary logistic regression approach is slightly less efficient than a joint model for the ordinal response. However, model building, investigating goodness-of-fit, and interpretation of the results is much easier for binary responses. The careful application of separate binary logistic regressions represents a simple and adequate tool to analyze ordinal data with non-proportional odds.

Abstract
Since 1990 in most Eastern European countries health care systems have been decentralized or are undergoing the processes of decentralization. Increasingly, diabetic patients are no longer treated by diabetologists but by non-specialized physicians. During the same period structured treatment and teaching programmes have been introduced and health care is increasingly influenced by the St. Vincent declaration. To show the effect of these changes on the quality of diabetes care 90% (n = 244) of all insulin-treated diabetic patients aged 16 to 60 years and living in the city of Jena (100247 inhabitants) were studied in 1994/1995. The results were compared with the baseline examination of 1989/1990 (n = 190). HbA1c (HbA1c/mean normal) in IDDM patients under specialized care was similar in 1994/1995 (1.54 +/- 0.27, n = 47) to 1989/1990 (1.52 +/- 0.31, n = 131, p = 0.0018), but higher under non-specialized care (1.71 +/- 0.38, n = 80, p = 0.0087). In the total group of NIDDM patients there was no significant change in HbA1c (1994/1995: 1.75 +/- 0.4, n = 117, vs 1989/1990: 1.78 +/- 0.4, n = 59, p = 0.67), but with a tendency to higher HbA1c under non-specialized (1.81 +/- 0.4, n = 79) compared to specialized care (1.66 +/- 0.39, n = 38, p = 0.06). Incidence of severe hypoglycaemia (IDDM 0.13; NIDDM 0.04), ketoacidosis (0.02; 0.01) and the prevalence of nephropathy (21%; 35%) and neuropathy (24%; 38%) remained unchanged in comparison to 1989/1990, whereas there was an increase in the prevalence of diabetic retinopathy. Specialized care is mandatory for patients with IDDM.

Abstract
The purpose of the study was to assess quality of life in patients with IDDM in relation to the type of insulin therapy. Two patient cohorts were studied. In cohort A, 77 patients deliberately intensified their traditional insulin injection therapy from up to two daily injections with syringe to multiple daily injections with insulin-pen; in cohort B, 55 patients changed from intensive therapy with pen to insulin pump-treatment (CSII). The therapeutic regimens were changed during a 5-day in-patient treatment and teaching course. The DCCT questionnaire was applied before and up to 6 months after changing of therapy. Treatment satisfaction increased after intensification of insulin therapy in both groups, mainly due to greater flexibility with leisure-time activities, and with the diet. Pump-users reported reduced problems with hypoglycemia (P < 0.02). HbA1c indicating acceptable metabolic control already before the study, remained unchanged. Therapy-associated inconvenience, mainly in association with lifestyle, improved in IDDM patients deliberately intensifying their insulin therapy by pens or pumps (CSII). Pump-treatment, rather than pen-therapy, conferred particular protection from hypoglycaemia.

Abstract
In the DCCT, intensification of insulin therapy led to a threefold increase in the risk of severe hypoglycemia (defined as the need for third party assistance). The reasons for this strong exponential relationship appears to be unclear to date. The present trial, a long-term evaluation of a 5-day structured teaching and treatment programme (5-DTTP) for intensified conventional insulin therapy (ICT), was performed to elucidate factors determining HbA1c and the incidence of severe hypoglycemia. A total of 71 patients were examined at baseline and 45.5 +/- 4.2 months following participation in a 5-DTTP. Comparing the data at follow-up examination with baseline measurements. HbA1c improved (8.52 +/- 2.29% vs. 8.0 +/- 1.43%, P = 0.04), the frequency of daily insulin injections (3.1 +/- 1.6 vs. 4.8 +/- 0.8, P < 0.001) and weekly blood-glucose self-tests (5.2 +/- 8.9 vs. 25.5 +/- 9.6, P < 0.001) increased, and the incidence of severe hypoglycemia (glucose i.v., glucagon injection) remained stable (0.18 vs. 0.17, P = 0.99). But, comparing the 21 patients who suffered from severe hypoglycemia during the follow-up period with the 50 patients without hypoglycemia, no differences between the two groups were found with respect to metabolic control (7.70 +/- 1.48% vs. 8.21 +/- 1.43%, P = 0.17), quality of life or treatment satisfaction. However differences arose with respect to diabetes knowledge. In the group of 21 patients with severe hypoglycemia we identified certain crucial gaps in diabetes knowledge: insulin self-adjustment; dietary aspects; hypo- and hyperglycemia. Performing multiple regression analysis, strong correlations were found between HbA1c and diabetes knowledge (r = -0.58. P = 0.002 for 50 patients without hypoglycemia and r = -0.63, P = 0.05 for 21 patients with hypoglycemia). In the total group, the most important factors determining HbA1c, were diabetes knowledge (r = -0.055, P = 0.007) and daily insulin dosage/kg body weight (r = 2.13, P = 0.0008, R2 = 0.26). Intervention like education of patients on a continuous basis and modifications of the DTTP's with more information and training in the recognition and treatment of hypoglycemic episodes seems to be essential to prevent hypoglycemia and to improve the efficacy of DTTP's over longer periods of time.

Abstract
The objectives of the study were to assess the effects of moderate sodium restriction on blood pressure in insulin-dependent diabetic (IDDM) patients with nephropathy and high normal or mildly hypertensive blood pressure (primary objective), and to document possible associated changes of exchangeable body sodium, body volumes, components of the renin-angiotensin-aldosterone system, atrial natriuretic peptide, and catecholamines (secondary objective). Sixteen patients with untreated systolic blood pressure > or = 140 < 160 mmHg and/or diastolic blood pressure > or = 85 < 100 mmHg were included in a double-blind, randomized, placebo-controlled trial. After a 4-week run-in period on their usual diet and a 2-week dietary training period to reduce sodium intake to about 90 mmol/day, eight patients received 100 mmol/day sodium supplement (group 2) and eight patients a matching placebo (group 1) for 4 weeks while continuing on the reduced-sodium diet. Patients were examined at weekly intervals. Main response variables were mean values of supine and sitting systolic and diastolic blood pressure as measured in the clinic and by the patients at home. The differences in blood pressure between the beginning and the end of the blinded 4-week study period were calculated and the differences in changes between the two patient groups were regarded as the main outcome parameters. During the blinded 4-week study period, average urinary sodium excretion was 92 +/- 33 (mean +/- SD) mmol/day in group 1 and 199 +/- 52 mmol/day in group 2 (p = 0.0002). The differences in blood pressure changes between the two patient groups were 3.9(-1.2 to 9) mmHg [mean (95% confidence intervals)] for systolic home blood pressure, 0.9(-3.7 to 5.5) mmHg for diastolic home blood pressure, 4.9(-3.3 to 13.1) mmHg for clinic systolic blood pressure and 5.3(1 to 9.7 mmHg, p = 0.02) for clinic diastolic blood pressure. Combining all patients, there were relevant associations between changes of urinary sodium excretion and blood volume (Spearman correlation coefficient r = 0.57), blood pressure and angiotensin II (diastolic: r = -0.7; systolic: r = -0.48), and exchangeable body sodium and renin activity (r = -0.5). In conclusion, in this study of IDDM patients with nephropathy and high normal or mildly hypertensive blood pressure, a difference in sodium intake of about 100 mmol/day for a period of 4 weeks led to a slight reduction of clinic diastolic blood pressure. Studies including larger numbers of patients with various stages of nephropathy and hypertension are needed to definitely clarify the effects of sodium restriction in IDDM.

Abstract
OBJECTIVE To document that strict dietary regimen are not necessary in the context of intensified insulin therapy. DESIGN German multicentre, prospective cohort study; 6 years follow-up. SETTING Ambulatory examination using a mobile ambulance. SUBJECTS A total of 636 type 1 diabetic patients (age 33 +/- 7 years, diabetes duration 15 +/- 7 years; mean +/- SD), who had participated in a structured, 5-day, in-patient, group treatment and teaching programme for intensification of insulin therapy and liberalization of the diabetes diet 6 years prior to follow-up. MAIN OUTCOME MEASURES Relations between the extent to which patients practise a liberalized diet, the degree of metabolic control (HbA1c, severe hypoglycaemia, body mass index, cholesterol), and the patients' perceived burden through dietary treatment. RESULTS In the total patient group, HbA1c was 7.9 +/- 1.6%, and the incidence of severe hypoglycaemia was 0.17 cases per patient during the preceding year; 31% patients injected insulin < or = 3 times per day, 58% 4-7 times per day, and 11% used insulin pump therapy. Only 11% patients reported following a meal plan, whereas 89% continually changed timing and amount of carbohydrate intake; only 5% had the same number of meals every day, whereas as many as 20% varied the number of meals per day by four or more; 53% skipped main meals; 85% habitually consumed sugar or sugar containing foods. Patients with a higher degree of diet liberalization injected insulin or used an insulin pump therapy more frequently, and perceived their dietary treatment to be less burdensome. No clinically significant associations were found between the extent of diet liberalization and metabolic control. CONCLUSIONS Under the conditions where type 1 diabetic patients have the opportunity to participate in an intensified insulin treatment and teaching programme, liberalization of the diabetes diet is not associated with adverse effects on glycaemic control, but is associated with less perceived burden through dietary treatment.

Abstract
The Diabetes Education Study Group (DESG) of the European Association for the Study of Diabetes (EASD) was founded in 1979 with its major goal to make effective patient training an integral part of any diabetes therapy. Within the DESG, a number of models for structured diabetes treatment and teaching programmes were developed. Concerning the care of persons with Type 1 diabetes, substantial emphasis was placed upon the 5-day in-patient treatment and teaching programme for groups of 6 to 10 patients as originally introduced at the University of Geneva and further developed for general use at the University of Düsseldorf. During the early 1980s, this programme was based upon intensified insulin therapy including a stepwise liberalization of previously rigid rules for nutrition and life schedules. In several European centres the programme was continuously evaluated and shown to be effective as documented by significant reductions of glycated haemoglobin values, episodes of ketoacidosis, hospitalizations, and sick-day leaves. In contrast to the Diabetes Control and Complications Trial (DCCT) the improvement of glycated haemoglobin values was not associated with an increased risk of severe hypoglycaemia. Possible reasons for this favourable outcome are discussed. During recent years the 5-day treatment and teaching programme for Type 1 diabetes has been translated into the general health care system of Germany without any loss of its efficacy. In addition, in various other European countries, model centres of diabetes care have implemented the 5-day programme, and for a number of these centres, its efficacy to improve the overall quality of diabetes care has been published or presented at meetings.

Abstract
The aim of the study was to identify predictors of long-term glycaemic control in Type 1 diabetic patients after participation in an intensified insulin treatment and teaching programme. The study population consisted of 697 Type 1 diabetic patients (mean age 26 +/- 7 (SD) years, duration of diabetes 8 +/- 7 years) who participated in the same structured intensified insulin treatment and teaching programme in 10 hospitals and who were re-examined after 1, 2, and 3 years. Multiple and logistic regression analyses were performed including a set of demographic, disease-related, social, and psychosocial variables as potential predictors. As dependent variables the average HbA1 values during the 3-year follow-up period and a composite variable (average HbA1 values/frequency of severe hypoglycaemia)--dividing patients into three groups with good, moderate or poor metabolic control--were considered. Regression analysis of average HbA1 values revealed significance (p < 0.05) for seven independent predictors in descending order: smoking, age at onset of diabetes, frequency of home blood glucose monitoring, socioeconomic status, diabetes-related knowledge, perceived coping abilities, and sex (R2 (percentage of variation explained by the model) = 17%). In a second regression model, HbA1 values before the intervention programme were added to the model and achieved the highest standardized regression coefficient (0.38), increasing R2 to 29%. In the logistic regression models considering both HbA1 and severe hypoglycaemia as a composite dependent variable, diabetes-related knowledge, HbA1 values before the intervention, smoking, perceived coping abilities, age at onset of diabetes, and C-peptide levels were the strongest predictors of glycaemic control. In conclusion, the relationship between demographic, disease-related, psychosocial, and social variables and metabolic control is complex. Therefore, simplistic concepts of linear causality should be abandoned. In addition to HbA1 values before the intervention, smoking, diabetes-related knowledge, home blood glucose monitoring, age at onset of diabetes, perceived coping abilities and C-peptide levels were the most significant and consistent predictors of glycaemic control.

Abstract
In a prospective controlled trial the effects of a 5-day in-patient treatment and teaching programme for Type 1 (insulin-dependent) diabetes mellitus on metabolic control and health care costs were studied in Moscow. Two different intervention programmes were compared, one based upon urine glucose self-monitoring (UGSM, n = 61) and one using blood glucose self-monitoring (BGSM, n = 60). Follow-up was 2 years. A control group (n = 60) continued the standard treatment of the Moscow diabetes centre and was followed-up for 1 year. Costs and benefits with respect to hospitalizations and lost productivity (according to average wage) were measured in November 1992 rubles (Rb.), with respect to imported drugs and test strips in 1992 German marks (DM). In the intervention groups there were significant decreases of HbA1 values [UGSM: 12.5% before, 9.4% after 1 year, 9.2% after 2 years (p < 0.0001); BGSM: 12.6% before, 9.3% after 1 year, 9.2% after 2 years (p < 0.0001) compared to no change in the control group (12.2% before, 12.3% after 1 year)], and of the frequency of ketoacidosis. The frequency of severe hypoglycaemia was comparable between the UGSM (10 cases during 2 years), BGSM (10 cases during 2 years), and the control group (8 cases during 1 year).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The Diabetes Education Study Group of the European Diabetes Association was founded in 1979 with its major goal to make effective patient training an integral part of any diabetes therapy. However, even today, in many places diabetes education is not an obligatory part of treatment, but is regarded as an optional service to the patient which is frequently fragmentary and haphazard. On the other hand, many physicians still subject their patients to rigid dietary instructions and obedience training, an approach which is mistaken for diabetes education. Several misconceptions about diabetes education keep counteracting the spread and hence the availability of effective treatment and teaching programmes for all Type 1 diabetic patients. One such misconception is that diabetes education could compensate for deficiencies of inappropriate insulin treatment regimens. Studies failing to demonstrate the impact of diabetes education on metabolic control, typically used an insulin treatment regimen with only one or two insulin injections per day, the predominant use of intermediate acting insulin preparations, and without (day-to-day) adjustment of insulin dosages by the patients themselves. A further reason for a lack of success of diabetes education is an unstructured approach which is frequently mistaken for individualized care. The deleterious effects of putting patients on intensified insulin therapy without offering them sufficient and systematic training have manifested themselves at various places by an excessive increase in the risk of severe hypoglycaemia, and of ketoacidosis during therapy with continuous subcutaneous insulin infusion. The effective and safe performance of insulin therapy requires both a rational system of insulin substitution and intensive training of the patients to carry it out. The injection of regular insulin before main meals and the use of intermediate or long-acting insulin preparations for the substitution of basal insulin requirements combined with daily metabolic self-monitoring and (day-to-day) adaptation of insulin dosages by the patients themselves allow a substantial improvement of glycaemic control without an increase in the risk of severe hypoglycaemia and the adoption of a more flexible life style largely freed from forcing and directive dietary and other impositions. Each diabetes centre should continuously evaluate the quality of care offered to their patients as a basis for a specific and systematic improvement of its treatment and education programmes. Such quality control measures must include a recording of the patients' degree of metabolic control and the frequencies of severe hypoglycaemia and ketoacidosis.(ABSTRACT TRUNCATED AT 400 WORDS)
