Theoretical foundations of TQM and CQI: or, does quality really have its own theory?

Total quality management and continuous quality improvement have been advocated as management salvation and anecdotally have been linked to improvements in operational effectiveness. The Joint Commission on Accreditation of Healthcare Organizations has adopted quality management as the organization improvement measure of the future and has mandated its application. The article explores the theoretical foundations of quality management and presents an integrated model dealing with this industry standard. An operational framework for managers is provided in an attempt to demystify the quality jargon that is so prevalent. The article also provides a prescriptive management overview incorporating quality management techniques into everyday operations.

[Optimizing the antibiotics policy in the Netherlands. IV. SWAB- guidelines for antimicrobial therapy of adults with sepsis in hospitals. Foundation Antibiotics Policy Work Group].

The Stichting Werkgroep Antibioticabeleid (SWAB, Foundation Antibiotic Policy Team) issued guidelines for empirical antimicrobial therapy in the hospital of sepsis in adults. A distinction is made between sepsis in patients with and patients without neutropenia. Patients without neutropenia are subdivided according to the setting where they contracted sepsis: at home, in the hospital or in the intensive-care unit. Because of the diversity in antibiotic spectrum of the different classes of cephalosporins, they can be used in all the categories of sepsis. The use of antibiotics with a very broad spectrum, like carbapenems and piperacillin-tazobactam, or antibiotics which can be applied in infections with microorganisms difficult to treat, like quinolones and glycopeptides, is limited in the empirical treatment of sepsis in order to combat development of resistance. It is crucial to streamline antibiotic therapy as soon as the causative agent of the sepsis is known; this includes choosing an antibiotic with the narrowest possible spectrum.

Lifestyle modifications to prevent and control hypertension. 1. Methods and an overview of the Canadian recommendations. Canadian Hypertension Society, Canadian Coalition for High Blood Pressure Prevention and Control, Laboratory Centre for Disease Control at Health Canada, Heart and Stroke Foundation of Canada.

OBJECTIVE: To provide updated, evidence-based recommendations for health care professionals on lifestyle changes to prevent and control hypertension in otherwise healthy adults (except pregnant women). OPTIONS: For people at risk for hypertension, there are a number of lifestyle options that may avert the condition--maintaining a healthy body weight, moderating consumption of alcohol, exercising, reducing sodium intake, altering intake of calcium, magnesium and potassium, and reducing stress. Following these options will maintain or reduce the risk of hypertension. For people who already have hypertension, the options for controlling the condition are lifestyle modification, antihypertensive medications or a combination of these options; with no treatment, these people remain at risk for the complications of hypertension. OUTCOMES: The health outcomes considered were changes in blood pressure and in morbidity and mortality rates. Because of insufficient evidence, no economic outcomes were considered. EVIDENCE: A MEDLINE search was conducted for the period January 1996 to September 1996 for each of the interventions studied. Reference lists were scanned, experts were polled, and the personal files of the authors were used to identify other studies. All relevant articles were reviewed, classified according to study design and graded according to level of evidence. VALUES: A high value was placed on the avoidance of cardiovascular morbidity and premature death caused by untreated hypertension. BENEFITS, HARMS AND COSTS: Lifestyle modification by means of weight loss (or maintenance of healthy body weight), regular exercise and low alcohol consumption will reduce the blood pressure of appropriately selected normotensive and hypertensive people. Sodium restriction and stress management will reduce the blood pressure of appropriately selected hypertensive patients. The side effects of these therapies are few, and the indirect benefits are well known. There are certainly costs associated with lifestyle modification, but they were not measured in the studies reviewed. Supplementing the diet with potassium, calcium and magnesium has not been associated with a clinically important reduction in blood pressure in people consuming a healthy diet. RECOMMENDATIONS: (1) It is recommended that health care professionals determine the body mass index (weight in kilograms/[height in metres]2) and alcohol consumption of all adult patients and assess sodium consumption and stress levels in all hypertensive patients. (2) To reduce blood pressure in the population at large, it is recommended that Canadians attain and maintain a healthy body mass index. For those who choose to drink alcohol intake should be limited to 2 or fewer standard drinks per day (maximum of 14/week for men and 9/week for women). Adults should exercise regularly. (3) To reduce blood pressure in hypertensive patients, individualized therapy is recommended. This therapy should emphasize weight loss for overweight patients, abstinence from or moderation in alcohol intake, regular exercise, restriction of sodium intake and, in appropriate circumstances, individualized cognitive behaviour modification to reduce the negative effects of stress. VALIDATION: The recommendations were reviewed by all of the sponsoring organizations and by participants in a satellite symposium of the fourth international Conference on Preventive Cardiology. They are similar to those of the World Hypertension League and the Joint National committee, with the exception of the recommendations on stress management, which are based on new information. They have not been clinically tested.

Lifestyle modifications to prevent and control hypertension. 2. Recommendations on obesity and weight loss. Canadian Hypertension Society, Canadian Coalition for High Blood Pressure Prevention and Control, Laboratory Centre for Disease Control at Health Canada, Heart and Stroke Foundation of Canada.

OBJECTIVE: To provide updated, evidence-based recommendations concerning the effects of weight loss and maintenance of healthy weight on the prevention and control of hypertension in otherwise healthy adults (except pregnant women). OPTIONS: The main options are to attain and maintain a healthy body weight (body mass index [BMI] 20-25 kg/m2) or not to do so. For those at risk for hypertension, weight loss and maintenance of healthy weight may prevent the condition. For those who have hypertension, weight loss and maintenance of healthy weight may reduce or obviate the need for antihypertensive medications. OUTCOMES: The health outcome considered was change in blood pressure. Because of insufficient evidence, no economic outcomes were considered. EVIDENCE: A MEDLINE search was conducted for the years 1992-1996 with the terms hypertension and obesity in combination and antihypertensive therapy and obesity in combination. Other relevant evidence was obtained from the reference lists of the articles identified, from the personal files of the authors and through contacts with experts. The articles were reviewed, classified according to study design and graded according to level of evidence. VALUES: A high value was placed on the avoidance of cardiovascular morbidity and premature death caused by untreated hypertension. BENEFITS, HARMS AND COSTS: Weight loss and the maintenance of healthy body weight reduces the blood pressure of both hypertensive and normotensive people. The indirect benefits of a health body weight are well known. The negative effects of weight loss are primarily the frustrations associated with attaining and maintaining a healthy weight. The costs associated with weight loss programs were not measured in the studies reviewed. RECOMMENDATIONS: (1) It is recommended that health care professionals determine weight (in kilograms), height (in metres) and BMI for all adults. (2) To reduce blood pressure in the population at large, it is recommended that Canadians attain and maintain a healthy BMI (20-25). (3) All overweight hypertensive patients (BMI greater than 25) should be advised to reduce their weight. VALIDATION: These recommendations are similar to those of the World Hypertension League, the National High Blood Pressure Education Program Working Group on Primary Prevention of Hypertension, the Canadian Hypertension Society and the Canadian Coalition for High Blood Pressure Prevention and Control. They have not been clinically tested. SPONSORS: The Canadian Hypertension Society, the Canadian Coalition for High Blood Pressure Prevention and Control, the Laboratory Centre for Disease Control at Health Canada, and the Heart and Stroke Foundation of Canada.

Lifestyle modifications to prevent and control hypertension. 4. Recommendations on physical exercise training. Canadian Hypertension Society, Canadian Coalition for High Blood Pressure Prevention and Control, Laboratory Centre for Disease Control at Health Canada, Heart and Stroke Foundation of Canada.

OBJECTIVE: To provide updated, evidence-based recommendations for health care professionals concerning the effects of regular physical activity on the prevention and control of hypertension in otherwise healthy adults. OPTIONS: People may engage in no, sporadic or regular physical activity that may be of low, moderate or vigorous intensity. For sedentary people with hypertension, the options are to undertake or maintain regular physical activity and to avoid or moderate medication use; to use another lifestyle modification technique; to commence or continue antihypertensive medication; or to take no action and remain at increased risk of cardiovascular disease. OUTCOMES: The health outcomes considered were changes in blood pressure and in morbidity and mortality rates. Because of insufficient evidence, no economic outcomes were considered. EVIDENCE: A MEDLINE search was conducted for the period 1966-1997 with the terms exercise, exertion, physical activity, hypertension and blood pressure. Both reports of trials and review articles were obtained. Other relevant evidence was obtained from the reference lists of these articles, from the personal files of the authors and through contacts with experts. The articles were reviewed, classified according to study design and graded according to level of evidence. VALUES: A high value was placed on avoidance of cardiovascular morbidity and premature death caused by untreated hypertension. BENEFITS, HARMS AND COSTS: Physical activity of moderate intensity involving rhythmic movements with the lower limbs for 50-60 minutes, 3 or 4 times per week, reduces blood pressure and appears to be more effective than vigorous exercise. Harm is uncommon and is generally restricted to the musculoskeletal injuries that may occur with any repetitive activity. Injury occurs more often with jogging than with walking, cycling or swimming. The costs include the costs of appropriate shoes, garments and equipment, but these were not specifically measured. RECOMMENDATIONS: (1) People with mild hypertension should engage in 50-60 minutes of moderate rhythmic exercise of the lower limbs, such as brisk walking or cycling, 3 or 4 times per week to reduce blood pressure, (2) Exercise should be prescribed as an adjunctive therapy for people who require pharmacologic therapy for hypertension, especially those who are not receiving beta-blockers. (3) People who do not have hypertension should participate in regular exercise as it will decrease blood pressure and reduce the risk of coronary artery disease, although there is no direct evidence that it will prevent hypertension. VALIDATION: These recommendations agree with those of the World Hypertension League, the American College of Sports Medicine, the report of the US Surgeon General on physical activity and health, and the US National Institutes of Health Consensus Development Panel on Physical Activity and Cardiovascular Health. These guidelines have not been clinically tested. SPONSORS: The Canadian Hypertension Society, the Canadian Coalition for High Blood Pressure Prevention and Control, the Laboratory Centre for Disease Control at Health Canada, and the Heart and Stroke Foundation of Canada.

Lifestyle modifications to prevent and control hypertension. 5. Recommendations on dietary salt. Canadian Hypertension Society, Canadian Coalition for High Blood Pressure Prevention and Control, Laboratory Centre for Disease Control at Health Canada, Heart and Stroke Foundation of Canada.

OBJECTIVE: To provide updated, evidence-based recommendations concerning the effects of dietary salt intake on the prevention and control of hypertension in adults (except pregnant women). The guidelines are intended for use in clinical practice and public education campaigns. OPTIONS: Restriction of dietary salt intake may be an alternative to antihypertensive medications or may supplement such medications. Other options include other nonpharmacologic treatments for hypertension and no treatment. OUTCOMES: The health outcomes considered were changes in blood pressure and in morbidity and mortality rates. Because of insufficient evidence, no economic outcomes were considered. EVIDENCE: A MEDLINE search was conducted for the period 1966-1996 using the terms hypertension, blood pressure, vascular resistance, sodium chloride, sodium, diet, sodium or sodium chloride dietary, sodium restricted/reducing diet, clinical trials, controlled clinical trial, randomized controlled trial and random allocation. Both trials and review articles were obtained, and other relevant evidence was obtained from the reference lists of the articles identified, from the personal files of the authors and through contacts with experts. The articles were reviewed, classified according to study design and graded according to level of evidence. In addition, a systematic review of all published randomized controlled trials relating to dietary salt intake and hypertension was conducted. VALUES: A high value was placed on the avoidance of cardiovascular morbidity and premature death caused by untreated hypertension. BENEFITS, HARMS AND COSTS: For normotensive people, a marked change in sodium intake is required to achieve a modest reduction in blood pressure (there is a decrease of 1 mm Hg in systolic blood pressure for every 100 mmol decrease in daily sodium intake). For hypertensive patients, the effects of dietary salt restriction are most pronounced if age is greater than 44 years. A decrease of 6.3 mm Hg in systolic blood pressure and 2.2 mm Hg in diastolic blood pressure per 100 mmol decrease in daily sodium intake was observed in people of this age group. For hypertensive patients 44 years of age and younger, the decreases were 2.4 mm Hg for systolic blood pressure and negligible for diastolic blood pressure. A diet in which salt is moderately restricted appears not to be associated with health risks. RECOMMENDATIONS: (1) Restriction of salt intake for the normotensive population is not recommended at present, because of insufficient evidence demonstrating that this would lead to a reduced incidence of hypertension. (2) To avoid excessive intake of salt, people should be counselled to choose foods low in salt (e.g., fresh fruits and vegetables), to avoid foods high in salt (e.g., pre-prepared foods), to refrain from adding salt at the table and minimize the amount of salt used in cooking, and to increase awareness of the salt content of food choices in restaurants. (3) For hypertensive patients, particularly those over the age of 44 years, it is recommended that the intake of dietary sodium be moderately restricted, to a target range of 90-130 mmol per day (which corresponds to 3-7 g of salt per day). (4) The salt consumption of hypertensive patients should be determined by interview. VALIDATION: These recommendations were reviewed by all of the sponsoring organizations and by participants in a satellite symposium of the fourth International Conference on Preventive Cardiology. They have not been clinically tested. SPONSORS: The Canadian Hypertension Society, the Canadian Coalition for High Blood Pressure Prevention and Control, the Laboratory Centre for Disease Control at Health Canada, and the Heart and Stroke Foundation of Canada.

Lifestyle modifications to prevent and control hypertension. 6. Recommendations on potassium, magnesium and calcium. Canadian Hypertension Society, Canadian Coalition for High Blood Pressure Prevention and Control, Laboratory Centre for Disease Control at Health Canada, Heart and Stroke Foundation of Canada.

OBJECTIVE: To provide updated, evidence-based recommendations on the consumption, through diet, and supplementation of the cations potassium, magnesium and calcium for the prevention and treatment of hypertension in otherwise healthy adults (except pregnant women). OPTIONS: Dietary supplementation with cations has been suggested as an alternative or adjunctive therapy to antihypertensive medications. Other options include other nonpharmacologic treatments for hypertension. OUTCOMES: The health outcomes considered were changes in blood pressure and in morbidity and mortality rates. Because of insufficient evidence, no economic outcomes were considered. EVIDENCE: A MEDLINE search was conducted for the period 1966-1996 with the terms hypertension and potassium, magnesium and calcium. Reports of trials, meta-analyses and review articles were obtained. Other relevant evidence was obtained from the reference lists of articles identified, from the personal files of the authors and through contacts with experts. The articles were reviewed, classified according to study design, and graded according to the level of evidence. VALUES: A high value was placed on the avoidance of cardiovascular morbidity and premature death caused by untreated hypertension. BENEFITS, HARMS AND COSTS: The weight of the evidence from randomized controlled trials indicates that increasing intake of or supplementing the diet with potassium, magnesium or calcium is not associated with prevention of hypertension, nor is it effective in reducing high blood pressure. Potassium supplementation may be effective in reducing blood pressure in patients with hypokalemia during diuretic therapy. RECOMMENDATIONS: For the prevention of hypertension, the following recommendations are made: (1) The daily dietary intake of potassium should be 60 mmol or more, because this level of intake has been associated with a reduced risk of stroke-related mortality. (2) For normotensive people obtaining on average 60 mmol of potassium daily through dietary intake, potassium supplementation is not recommended as a means of preventing an increase in blood pressure. (3) For normotensive people, magnesium supplementation is not recommended as a means of preventing an increase in blood pressure. (4) For normotensive people, calcium supplementation above the recommended daily intake is not recommended as a means of preventing an increase in blood pressure. For the treatment of hypertension, the following recommendations are made. (5) Potassium supplementation above the recommended daily dietary intake of 60 mmol is not recommended as a treatment for hypertension. (6) Magnesium supplementation is not recommended as a treatment for hypertension. (7) Calcium supplementation above the recommended daily dietary intake is not recommended as a treatment for hypertension. VALIDATION: These guidelines are consistent with the results of meta-analyses and recommendations made by other organizations. They have not been clinically tested.

Lifestyle modifications to prevent and control hypertension. 7. Recommendations on stress management. Canadian Hypertension Society, Canadian Coalition for High Blood Pressure Prevention and Control, Laboratory Centre for Disease Control at Health Canada, Heart and Stroke Foundation of Canada.

OBJECTIVE: To provide updated evidence-based recommendations for health care professionals concerning the effects of stress management on the prevention and control of hypertension in otherwise healthy adults (except pregnant women). OPTIONS: Alternatives to stress management include other nonpharmacologic interventions and medical therapy; these options are not mutually exclusive. OUTCOMES: The health outcome considered was reduction of blood pressure. There is little evidence to date that stress management prevents death or vascular events. Because of insufficient evidence, no economic outcomes were considered. EVIDENCE: A systematic search of the literature (which yielded, among other sources, 3 meta-analyses) was conducted for the period 1966-1997 with the terms essential hypertension, treatment, psychological, behavioural, cognitive, relaxation, mediation, biofeedback and stress management. Other relevant evidence was obtained from the reference lists of the articles identified, from the personal files of the authors and through contacts with experts. The articles were reviewed, classified according to study design and graded according to level of evidence. VALUES: A high value was placed on the avoidance of cardiovascular morbidity and premature death caused by uncontrolled hypertension. BENEFITS, HARMS AND COSTS: The magnitude of the reduction in blood pressure obtained with multicomponent, individualized cognitive behavioural intervention for stress management was comparable in some studies to that obtained with weight loss or drugs; single-component interventions such as biofeedback or relaxation were less effective. The adverse effects of stress-management techniques are minimal, but the cost for effective interventions is substantial, similar initially to drug costs; continuing costs are probably minimal. RECOMMENDATIONS: (1) In patients with hypertension, the contribution of stress should be considered. (2) For hypertensive patients in whom stress appears to be an important issue, stress management should be considered as an intervention. Individualized cognitive behavioural interventions are more likely to be effective than single-component interventions. VALIDATION: These recommendations were reviewed by all of the sponsoring organizations and by participants in a satellite symposium of the fourth International Conference on Preventive Cardiology. They have not been clinically tested.

Educational factors affecting modality selection: a National Kidney Foundation study.

Patient education has been found to have significant positive effects in a multitude of studies. The National Kidney Foundation undertook a study to examine the various factors that impact upon treatment modality selection, with this paper focusing specifically on the study's educational components. The majority of these respondents reported receiving an adequate amount of information, yet routinely they were not offered information on all treatments available to them. While most indicated being educated by one-to-one discussions, other methods were also employed. Those responding were most likely to receive education from nephrologists, however, nursing was involved with 46% of the participants.

Characteristics of insomnia in the United States: results of the 1991 National Sleep Foundation Survey. I.

The National Sleep Foundation in conjunction with the Gallup Organization conducted telephone interviews with a sample of Americans (N = 1000) to examine the prevalence and nature of difficulty with sleep. Consistent with other national studies, about one-third of Americans reported some type of sleep problem. Approximately one in four reported occasional insomnia while 9% reported that their sleep difficulty occurred on a regular nightly basis. The problem most frequently reported by insomniacs was waking up in the morning feeling drowsy or tired, followed by waking up in the middle of the night, difficulty going back to sleep after waking up and difficulty falling asleep initially. Importantly, insomniacs rarely visited a physician to discuss their sleep problem and four out of ten insomniacs self-medicated with either over-the-counter medications or with alcohol. Two-thirds of the insomniacs reported that they did not have an understanding of available treatments for insomnia.

Daytime consequences and correlates of insomnia in the United States: results of the 1991 National Sleep Foundation Survey. II.

The daytime consequences and correlates of insomnia were examined in the National Sleep Foundation and the Gallup Organization survey of 1,000 randomly selected Americans. Respondents were grouped as having occasional insomnia, chronic insomnia or no insomnia. There were dramatic differences in reported waking behaviors and psychosocial measures by insomniacs compared to those who do not report sleep difficulty. These problems include impaired concentration, impaired memory, decreased ability to accomplish daily tasks and decreased enjoyment of interpersonal relationships. Importantly, most of these variables showed an increasing degree of impairment with greater frequency of sleep disturbance. These findings suggest that insomnia negatively impacts aspects of waking function related to quality of life.

[A plea for the foundation of a counseling center for people using artificial respiration and their relatives].

BACKGROUND AND AIMS: Since the 1980s the group of people surviving with the aid of artificial respiration has expanded. So far, however, no information centre for such persons exists in Germany. Likewise, peer counselling is not a widely accepted method of allocating responsibility to afflicted persons. The task of an information centre would be to provide peer counselors who would advise people on artificial respiration. PATIENTS AND METHODS: Interviews with subjects and their relatives regarding the various aspects of artificial respiration. CONCLUSION: The foundation of such a counselling centre is recommended on account of the present need for a national information exchange and contact centre.

[The "Hersbruck Model". Application and integration of the DIN EN ISO 9001 quality norms with criteria of the European Foundation for Quality Management in a clinic].

The german health system has dramatically changed and still continues to do so. Modified aspects concerning economy, customer orientation, competition, quality assurance and quality management seem to be increasingly important. Appropriate response to this challenge demands a relevant adjustment of a quality "philosophy" within a hospital. The "Hersbruck Model" has proven to be a suitable approach: on the basis of a quality management system--established and certified according to DIN EN ISO 9001--it implements all components of the model of the European Foundation for Quality Management. The modern quality tools as Total Quality Management and continuous quality improvement allow a permanent increase of customer/patient satisfaction.

Integrated databases--the foundation for the information linking of the actors in the national health care and health insurance systems.

Among the characteristics of the present time, we meet the ranking of information among the key resources of effective management of business systems. Up to date, integral and accurate information have gained precedence over conventional economic resources. This applies particularly in the case of large and complex business systems, including the national health care and health insurance systems. High quality and unified databases form the foundation for rational and quality procedures ranging from the operative level to the national strategy level. The goal of this paper is to demonstrate, on the example of Slovene experience, the importance of keeping quality databases for the purposes of health care and health insurance system management. The paper reviews the achieved level and the plans of further development of unified databases in this sector in Slovenia. The key emphasis in the development of an integrated system has been laid upon establishing uniform primary databases and providing appropriate integration in the area of data interchange among the actors of the health care and health insurance systems and other national systems.

Resin composites for foundation restorations.

This study focused on the compressive properties of two core buildup materials, Ti-Core, (EDS, Inc.) and FluoroCore, (L.D. Caulk). Specimens were 0.6 x 1.2 cm cylinders, Prior to testing, the specimens were aged in a moist environment for one, seven, or 28 day(s). The properties of interest were compressive strength, modulus of elasticity and toughness. The data set for each of the three compressive properties was subjected to a separate two-way analysis of variance. Scheffé F-tests were used to compare means. Whereas the effect of material on each of the three properties was significant (p < 0.002), the effects of specimen age (p > 0.400) and material x specimen age (p > 0.350) were not significant. FluoroCore was stronger and tougher than Ti-Core. On the other hand, Ti-Core displayed the highest stiffness, but ruptured brittley. The moderately low strength of Ti-Core, and the insufficient elastic modulus of FluoroCore, avert favorable recommendations pertaining to the construction of foundation restorations.
