[Necessity and Ways to Develop Care Goals for the Health System in Germany - a Position Paper of the DNVF].

Goals for health and health care are an indispensable basic requirement for a functioning health care system. The dilemma of the German health care system is that it has not been designed in a planned way, but that it has grown historically. In recent years, it has developed through the free play of forces into what it is today.

[Benchmarking of public hospitals using the example of "4QD-Qualitätskliniken.de"].

Patients and their relatives can use to the portal Qualitätskliniken.de to individually search for hospitals in their neighbourhood. The search criteria include: diagnosis, types of treatment or specialised departments.

DIABCARE Quality Network in Europe--a model for quality management in chronic diseases.

The DIABCARE Q-Net project developed a complete and integrated information technology system to monitor diabetes care, according to the gold standards of the St Vincent Declaration Action Program. This is the first Telematic platform for standardized documentation on medical quality and evaluation across Europe, which will serve as a model for other chronic diseases. Quality development starts from the comparison of diabetes services, based on the key data on diabetes care in the basic information sheet.

Quality management in psychiatry.

Over the past 50 years, treatment possibilities in psychiatry have drastically improved, but the results we actually achieve under everyday treatment conditions fall far short of what could be accomplished. Quality management represents a suitable method of reducing this gap. Although it has been successfully practiced in other medical disciplines for a long time, its implementation in psychiatry has previously been restricted to pilot projects.

The implementation of a quality-net as a part of the European project DIABCARE Q-Net.

DIABCARE Q-Net is a European project with a consortium of partners in healthcare, industry, and research, which has the overall target of improvement in diabetes care by aggregation, evaluation, and feedback of anonymized patient data with the tools of modern telematics, resulting from the initiative of the St. Vincent-Declaration, St. Vincent, Italy.

Screening of diabetic patients for microalbuminuria in primary care--The PROSIT-Project. Proteinuria Screening and Intervention.

The PROSIT (Proteinuria Screening and Intervention) Project started in 1993 in order to obtain data on the prevalence of micro- and macroalbuminuria in diabetic patients treated in primary care, to establish an easy screening programme for microalbuminuria, in which also diabetic patients can participate in self-responsibility, and to implement a specific intervention programme for incipient nephropathy. In 58 representative doctor's offices 647 diabetic patients were included, who performed at home self-tests for microalbuminuria on three days within one week using the early morning urine and a newly developed qualitative immunologic test-strip for microalbuminuria. After storage they returned the same urine samples to their doctors' offices for semiquantitative retesting with the immunologic test-strip Micral-Test II.

Postprandial blood glucose and its relation to diabetic gastroparesis--a comparison of two methods.

Delayed gastric emptying is known as an important organic cause for brittle diabetes. We proposed the interval from the start of a meal to the rise in blood glucose, defined as blood glucose latency (T BG) as an index for gastric emptying and a non-invasive test for diabetic gastropathy. In order to validate this test we compared it in 22 type 1 diabetic patients with an established scintigraphic method for the measurement of gastric half-emptying time (T1/2) and found the following correlation: T BG = 4.

Monitoring the targets of the St Vincent Declaration and the implementation of quality management in diabetes care: the DIABCARE initiative. The DIABCARE Monitoring Group of the St Vincent Declaration Steering Committee.

The St Vincent Declaration, a joint initiative on diabetes care and research of the World Health Organization (Europe) and the International Diabetes Federation (Europe), includes 5-year targets for improvement in diabetes outcomes as a central tenet. Accordingly, the establishment of state of the art monitoring and control systems is urged as a basis for the implementation of quality management. As a prerequisite for both targets, a diabetes dataset (fields and definitions) has been agreed to allow common monitoring of diabetes throughout Europe.

The feedback between monitoring and improvement of quality of diabetes care.

The need for permanent, population-wide, improvement in metabolic care of diabetic patients is generally accepted. This paper highlights some related aspects which must be considered by any health care provider: (1) Monitoring metabolic or other variables in diabetic patients is an essential tool in routine metabolic care, where a "short feedback" between monitored data and medical or behavioral measures is permanently established by the patients themselves, the physicians, the nurses etc. (2) Quality insurance requires the closure of a "long feedback" between informations and interventions, such as conditions, tools, methods, used at the different levels of the care system, from the individual patient to a population scale.

Advanced health care initiatives in Europe on quality development, epidemiology and medical documentation.

Since the St. Vincent Declaration was published in 1989, several different but logically linked activities have been initiated. In addition, there are projects in adjacent fields supporting each other by exchange of information and partial co-operation.

Is resistance to ischaemia of motor axons in diabetic subjects due to membrane depolarization?

The reasons for the resistance to ischaemia of peripheral nerves in diabetics are not well understood. We have now explored whether axonal depolarization underlies this phenomenon, as has previously been proposed. Resistance to ischaemia was determined by the new method of "threshold tracking".

Analysis and processing of data in a hospital-based diabetes management system.

Both short-term care (blood glucose monitoring) and long-term care (clinical examinations) of diabetes generate an ample amount of data for each patient. Health care in hospitals has to provide services with respect to both demands. The quality of control depends on obtaining the right finding at the right time and taking the individually adequate measures.

[The early breakfast--an unknown pitfall in the treatment of type-I diabetes mellitus].

In 15 type I diabetics the mean postprandial rise in blood glucose levels, 90 min after breakfast at about 8 a.m. (the customary time for this meal in hospitals), was 62.

Glucose control in mobile type 1 (insulin-dependent) diabetic patients by means of a semi-automatic feedback controlled insulin infusion system.

A portable insulin dosing device (Siemens) was used together with a programmable pocket calculator and a glucose analyzer for short-term adaptation of continuous intravenous insulin infusion to blood glucose alterations. A special algorithm was developed which utilizes a given blood glucose value and the glucose rate of change obtained from two to four consecutive samples as input variables. In contrast to current techniques of feedback-regulation, which require continuous glucose monitoring, intermittent blood sampling allows greater mobility of patients.

Control of insulin-dependent diabetes with portable miniaturized infusion systems.

A method of insulin therapy that appears to achieve better control of diabetes than present conventional methods is the use of insulin infusion devices--either glucose-controlled feedback (closed-loop) systems or the preprogrammed (open-loop) infusion pump. In view of the problems with implantable glucose sensors, we have worked to develop a miniaturized, programmable infusion system. Its use in insulin-dependent diabetic patients to provide either intravenous doses or a continuous subcutaneous insulin infusion resulted in significant reductions in blood glucose levels, glycemic excursions and 24-h glucose excretion.
