[Radiology in managed care environment: opportunities for cost savings in an HMO]

PURPOSE

A large regional health plan in the Northeastern United States noted that its radiology costs were increasing more than it anticipated in its pricing, and noted further that other similar health plans in markets with high managed care penetration had significantly lower expenses for radiology services. This study describes the potential areas of improvement and managed care techniques that were implemented to reduce costs and reform processes.

MATERIALS AND METHODS

We performed an in-depth analysis of financial data, claims logic, contracting with provider units and conducted interviews with employees, to identify potential areas of improvement and cost reduction. A detailed market analysis of the environment, competitors and vendors was accompanied by extensive literature, Internet and Medline search for comparable projects. All data were docu-mented in Microsoft Excel(R) and analyzed by non-parametric tests using SPSS(R) 8.0 (Statistical Package for the Social Sciences) for Windows(R).

RESULTS

The main factors driving the cost increases in radiology were divided into those internal or external to the HMO. Among the internal factors, the claims logic was allowing overpayment due to limitations of the IT system. Risk arrangements between insurer and provider units (PU) as well as the extent of provider unit management and administration showed a significant correlation with financial performance in terms of variance from budget. Among the external factors, shared risk arrangements between HMO and provider unit were associated with more efficient radiology utilization and overall improvement in financial performance. PU with full-time management had significantly less variance from their budget than those without. Finally, physicians with imaging equipment in their offices ordered up to 4 to 5 times more imaging procedures than physicians who did not perform imaging studies themselves.

CONCLUSION

We identified initiatives with estimated potential savings of approximately $ 5.5 million. Some of these initiatives are similar to the reforms to reduce cost and improve quality that are already implemented or proposed within the German healthcare system.

[Audits across state borders for medical consulting agencies within the German healthcare insurance system]

The Medizinischer Dienst der Krankenversicherung (MDK) is a non-profit medical consulting organisation serving the German Healthcare Insurance System. Despite its uniform commission throughout Germany, organisation and structure differ considerably between Provincial States which is reflected by differing results. A common nationwide system of key figures and indicators aims at analysing results and learning from one another.

AIM

Development of an audit concept for analysing key figures and indicators within the MDK aiming at quality improvement.

METHODS

Development of a system of key figures and indicators covering five spheres (products, staff, costs, data analysis, structure). Analysis by means of audits carried out across provincial state borders in five steps (audit manual, training of auditors, visitation, audit report, repetition audit).

RESULTS

The system of key figures and indicators assures relevant and comparable data. Audit manual, training of auditors, visitation, and audit report meet the needs of all people and institutions involved. Preparation of auditors as well as openness, and flow of information within audited organisations offer areas for improvement. There is as yet no assessment of the cost-benefit ratio of audits.

CONCLUSION

The concept presented in this article consists of two parts: A system of key figures and indicators as well as a concept for audits. The concept is suitable for a) generating and analysing relevant key figures and indicators for each MDK, and b) providing information for benchmarking between different MDK. Further development of the concept to a comprehensive management concept is necessary.

[Quality management in surgery--an overview of methods and possibilities]

Numerous methods of assessing quality in health care have been presented over the last years. Since the German health care reform of 2000 introduced a legal obligation to quality assurance, hospitals have to meet that condition. However, no specific system of quality assurance was implicated. Therefore, many potential users search for systems suiting their own needs. However, German hospitals can benefit from international experience in quality management. Accreditation, visitation, excellence schemes, and certification seem to be the dominant methods. Every method is worthy of hospital evaluation. Certifications illustrate the quality system view without regard to profession, while excellence schemes evaluate the development of quality management in hospitals. Accreditation portrays a specific hospital as a whole, while visitations follow the professional perspective of quality assurance. Depending on the perspective and aims, there are advantages and disadvantages in each method. Finally, a combination of two may also be helpful. Indeed, no "role model" exists yet for assessing quality in health care. These methods of quality management are applicable especially in surgery, because a variety of standard outcome parameters such as length of stay, duration of procedure, and complication and relapse rates are already available.

[Structural development of ambulatory surgical care in the United States of America. What can we learn or apply?]

Expansion of ambulatory surgical care is a major focus in United States health politics. In 1996 a total of 31.5 million ambulatory operations were performed, currently accounting for 45% of yearly procedures. Operations in ophthalmology and gastroenterology are predominant. Ambulatory surgery is organized in different forms: "office-based surgery," "hospital outpatient departments," and "ambulatory surgery centers" (ASC). The numbers of ASCs are rapidly increasing. The current proportion of ASCs is 16% of all operations. The type of ambulatory surgery is primarily defined by payors. Medicare standards are the benchmark for private organizations. Recovery care centers now offer postoperative care beyond the former 23-h threshold. This may lead to a further expanded ASC access. Revenues for ambulatory surgery were so far mostly based on fees for service. The implementation of an outpatient prospective payment system ("OPPS") is planned by Medicare, using fixed package prices within a newly defined ambulatory payment classification ("APC"). The dimension of structural changes could be enormous and possibly be compared with the implementation of DRGs in 1983.

Inhibition of granulocyte activation by surfactant in a 2-yr-old female with meningococcus-induced ARDS

Activated polymorphonuclear neutrophils (PMNs) play a crucial role in acute respiratory distress syndrome (ARDS) via extracellular release of reactive cell products such as elastase. Surfactant has proved valuable in restoring lung function in ARDS. The significance of its immunomodulatory properties with respect to this effect has not yet been clarified. The aim of the present study was to determine the anti-inflammatory effects of surfactant administration in an infant with ARDS. During the acute phase of ARDS in a 2-yr-old female, levels of PMN-derived elastase complexed with alpha1-protease inhibitor (E-alpha1PI) were measured in both arterial and central venous blood samples obtained simultaneously. The results were correlated with oxygen demand and plasma concentrations of tumour necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) after endotracheal administration of surfactant (Alveofact 60 mg x kg x body weight(-1)). In the present case, for the first time, a higher E-alpha1PI concentration was detected in arterial blood (4.51 mg x L(-1)) than in central venous blood (2.28 mg x L(-1)). After administration of surfactant, these concentrations and the arteriovenous difference decreased, indicating that during ARDS, most PMN degranulation takes place in the pulmonary vascular bed and is inhibited by surfactant administration. Simultaneously, TNF-alpha and IL-6 plasma concentrations decreased within hours and lung function was restored. This local inhibition of polymorphonuclear neutrophil activation by exogenous surfactant may play a key role in the early improvement in lung function after surfactant administration.

Selection pressure for the factor-V-Leiden mutation and embryo implantation

The factor-V-Leiden mutation is seen in high frequencies in white people, despite its contribution to second-trimester abortion, preterm birth, and deep-vein thrombosis. The reason for its high frequency is not known. We investigated 102 mother-child pairs who had had successful in-vitro fertilisation by intracytoplasmic sperm injection as a model for human implantation. In 90% (9 of 10) of mother-child pairs who carried factor-V-Leiden mutation, the first embryo transfer was successful, compared with 49% (45 of 92) in factor-V-Leiden negative pairs (p=0.018, Fisher's exact test). Furthermore, the median number of unsuccessful transfers was lower in pairs who were positive for the mutation (0, range 0-2) than those who were negative (1, 0-8) (p=0.02, Mann Whitney U test) suggesting that improved implantation rate is an important genetic advantage of the factor-V-Leiden mutation.

Sexual activity as a trigger of myocardial infarction. A case-crossover analysis in the Stockholm Heart Epidemiology Programme (SHEEP)

OBJECTIVE

To investigate sexual activity as a trigger of myocardial infarction and the potential effect modification of physical fitness.

DESIGN

A case-crossover study nested in the Stockholm Heart Epidemiology Programme (SHEEP).

SETTING

Stockholm County from April 1993 to December 1994.

PATIENTS

All patients with a first episode of non-fatal acute myocardial infarction admitted to coronary care units were eligible, and 699 patients participated in an interview.

MAIN OUTCOME MEASURES

Relative risks with 95% confidence intervals.

RESULTS

Only 1.3% of the patients without premonitory symptoms had sexual activity during two hours before the onset of myocardial infarction. The relative risk of myocardial infarction was 2.1 (95% confidence interval (CI) 0.7 to 6.5) during one hour after sexual activity, and the risk among patients with a sedentary life was 4.4 (95% CI 1.5 to 12.9).

CONCLUSIONS

The increased risk of myocardial infarction after sexual activity and the further increase in risk among the less physically fit support the hypothesis of causal triggering by sexual activity. However, the absolute risk per hour is very low, and exposure is relatively infrequent. Thus having sex once a week only increases the annual risk of myocardial infarction slightly. Counselling should focus on encouraging patients to live a physically active life and not on abstaining from sexual activity.

Low prevalence of large intraventricular haemorrhage in very low birthweight infants carrying the factor V Leiden or prothrombin G20210A mutation

The influence of genetic factors that increase coagulation on the extension of intraventricular haemorrhage (IVH) in very low birthweight infants has not been studied previously. This study investigated the frequency and effect of the factor V Leiden and prothrombin G20210A mutations in a population-based cohort of 305 preterm infants with a birthweight below 1500 g. The overall prevalence of IVH was similar in infants with (n = 43) and without (n = 262) prothrombotic mutations (18.6% vs 16.4%, respectively). However, infants with prothrombotic mutations had a significantly reduced risk of developing extension to IVH grade II or more [p = 0.023, odds ratio (OR) 0.11, 95% confidence interval (CI) 0.02-0.5]. The carrier state of a factor V Leiden or prothrombin G20210A mutation was still predictive for a low rate of IVH grade II-IV if possible confounding variables were included in a multivariate regression model (OR 0.12; 95%CI: 0.017-0.86).

CONCLUSION

The data suggest that the factor V Leiden and prothrombin G20210A mutations lead to improved control of intraventricular bleeding in very low birthweight infants.

Diagnostic and therapeutic problems in a case of prenatally detected fetal hydrocolpos

We report on a female fetus with prenatally suspected hydrometrocolpos. Postnatal evaluation additionally revealed ambiguous genitalia, anorectal atresia, vertebral segmentation anomalies and congenital intestinal aganglionosis. Colostomy was performed, but postoperative recovery was complicated by pulmonary hypertension and renal failure, resulting in death at day 18. Postmortem examination furthermore revealed a small ventricular septal defect, as well as rectovaginal and urethrovaginal fistulae, causing massive dilatation of the septated vagina (hydrocolpos). The possibility of an overlapping VACTERL and MURCS association is discussed.

[Effects of dimensional and social comparisons on ability assessment and satisfaction with performance]

The study deals with the question whether internal dimensional comparisons (comparisons of one's own achievement in a task with one's own achievement in another task) contribute to the development of task-specific self-evaluations. In an experimental study, N = 135 student subjects who had worked on two different types of tasks received manipulated achievement feedback with reference to dimensional and social comparisons. Results indicated the relevance of dimensional comparison information. Subjects scored their own ability and contentment with their result in the first type of task more positively (negatively) when they had received a better (worse) result than in the second task.

Does heavy physical exertion trigger myocardial infarction? A case-crossover analysis nested in a population-based case-referent study

To study possible triggering of first events of acute myocardial infarction by heavy physical exertion, the authors conducted a case-crossover analysis (1993-1994) within a population-based case-referent study in Stockholm County, Sweden (the Stockholm Heart Epidemiology Program). Interviews were carried out with 699 myocardial infarction patients after onset of the disease. These cases represented 47 percent of all cases in the study base, and 70 percent of all nonfatal cases. The relative risk from vigorous exertion was 6.1 (95% confidence interval: 4.2, 9.0). The rate difference was 1.5 per million person-hours, and the attributable proportion was 5.7 percent. The risk was modified by physical fitness, with an increased risk being seen among sedentary subjects as in earlier studies, but the data also suggested a U-shaped association. In addition, the trigger effect was modified by socioeconomic status. Premonitory symptoms were common, and this implies risks of reverse causation bias and misclassification of case exposure information that require methodological consideration. Different techniques (the use of the usual-frequency type of control information, a pair-matched analysis, and a standard case-referent analysis) were applied to overcome the threat of misclassification of control exposure information. A case-crossover analysis in a random sample of healthy subjects resulted in a relative risk close to unity, as expected.

Do episodes of anger trigger myocardial infarction? A case-crossover analysis in the Stockholm Heart Epidemiology Program (SHEEP)

OBJECTIVE

Our objectives were to study anger as a trigger of acute myocardial infarction (MI) and to explore potential effect modification by usual behavioral patterns related to hostility.

METHODS

This study was a case-crossover study within the Stockholm Heart Epidemiology Program. Exposure in the period immediately preceding MI was compared with exposure during a control period for each case. From April 1993 to December 1994, 699 patients admitted to coronary care units in Stockholm County were interviewed.

RESULTS

During a period of 1 hour after an episode of anger, with an intensity of at least "very angry," the relative risk of MI was 9.0 (95% CI, 4.4-18.2). In patients with premonitory symptoms, the time of disease initiation may be misclassified. When restricting the analyses to those without such symptoms, the trigger risk was 15.7 (95% CI, 7.6-32.4). The possibility of examining effect modification was limited by a lack of statistical power (eight exposed cases). Results of the analyses suggested, however, an increased trigger effect among subjects reporting nonhostile usual behavior patterns, nonovert strategies of coping with aggressive situations (not protesting when being treated unfairly), and nonuse of beta-blockers.

CONCLUSIONS

The hypothesis that anger may trigger MI is further supported, with an increased risk lasting for approximately 1 hour after an outburst of anger. It is suggested that the trigger risk may be modified by personal behavior patterns.

Intussusception in preterm infants: case report and literature review

Intussusception is an extremely rare disorder in preterm infants. An infant of 29 weeks gestational age with this condition is reported and a retrospective analysis of 17 previously reported cases presented. In the reviewed preterm infants, risk factors for intussusception seemed to be multifactorial. Clinical features included severe abdominal distension (17/17), gastric aspirates (13/17), commonly bilious, bloody stools (10/17) and rarely a palpable abdominal mass (5/17). Diagnostic features were signs of small bowel obstruction on the abdominal radiographs. Signs and symptoms were similar to those seen in necrotizing enterocolitis, therefore difficulties in establishing a correct diagnosis led to an average delay of 7 days between the onset of symptoms and abdominal surgery, increasing the risk of developing a compromised bowel.

CONCLUSION

The differential diagnosis of an intussusception should be considered in preterm infants with acute abdominal distension and tenderness.

Systematic analysis and controlling of health care organisations lead to numerical health care improvements

The EFQM model for organisational excellence is used in the health care sector as a tool to diagnose and assess the starting position for the effective QM programme. Feedback reports cover the fields of acute medical care, rehabilitation and ambulant care and contain strengths areas for improvement. Building on the EFQM feedback reports, the Modular Concept for Quality in Health Care ("Heidelberg Model") improves QM both holistically and specifically by implementing so-called "Modules for Excellence". The implementation process follows principles of project management covering medical, nursing and managing issues and the performance is periodically evaluated against targets. QM projects that are designed in the dichotomic way follow three goals. Organisational diagnosis and therapy lead to numerical health care improvements in "Prevention of nosocomial infections" and "Optimising out-patient treatment". Different assessment approaches lead to a diagnosing feedback report for QM in health care. The Modular Concept for Quality in Health Care ("Heidelberg Model") clusters, priorities, implements and evaluates the organisation's key areas for improvement.

Longitudinal, population-based study of self reported alcohol habits, high levels of sickness absence, and disability pensions

STUDY OBJECTIVE

To analyse the relation between self reported hazardous drinking on the one hand and high sickness absence and/or disability pensions in both sexes on the other hand.

DESIGN

The study is based on data from a health survey, Stockholm Health of the Population Study, conducted in 1984. The mailed questionnaire covered alcohol consumption. Three different measures of alcohol habits were used: usual alcohol consumption, consumption during the previous week, and answers to the four CAGE questions on problem drinking. Information from the health survey and data from a subsequent health examination were related to information from the National Swedish Social Insurance Board for the year 1984 and the years 1986 to 1991 concerning sick leave and disability pensioning.

SETTING

Four primary health care districts in Stockholm County.

PARTICIPANTS

The study group included persons who were aged 20 to 52 years in 1984, who answered the questionnaire (by mail or by telephone), and who participated in the health examination. The study group comprised 985 women and 870 men fulfilling the criteria for inclusion out of 6217 subjects aged 18 years and over randomly drawn.

MAIN RESULTS

In both sexes, a consistent pattern of increased sickness absence was seen for high consumers and for those with indications of problem drinking. In most comparisons, a clearly increased relative risk, although not always statistically significant, for an average of at least 60 sick days per year or for a disability pension during follow up was found. In multivariate analysis, controlling for age, socioeconomic group, smoking habits, and self reported health, a small reduction in the relative risks was found, suggesting that these factors could explain only a small part of the relative risks. The risks for abstainers were higher than for low and moderate consumers.

CONCLUSIONS

The effects of alcohol on subsequent high levels of sickness absence five to seven years after baseline as well as on the occurrence of disability pensions suggested that there is an effect on working incapacity independent of baseline health status, smoking, and socioeconomic group.

[Incidence of nosocomial infections as an element of cost-conscious quality management of inpatient care]

The prevention of nosocomial infections is a result of many variables in a wide range of architectural, personal and organisational decisions taken into account in modern hospital plannings. The frequency of nosocomial infections in a given period can be used as one possible indicator of outcome quality of our hospitals. Contrary to the frequently uttered claims of many experts, who demand for a continuous hygienic monitoring in hospitals [1;2;3;4], routine procedures have not been unanimously established until now. Assessment and evaluation of nosocomial infections seem to be anything but trivial. Purpose of the described pilot study at the University of Lubeck was the development and test of a set of practicable routines to early discover and assess nosocomial infections. Methods of epidemiologic evaluation have been implemented to grant a perpetuos hygienic monitoring even on a limited base of personal, structural and financial resources. In a next step, further adaptations and improvements are planned, thus making assessment and evaluation independent of central institutions.

[Persistent pulmonary hypertension in premature and newborn infants: selective pulmonary vasodilation with inhaled nitric oxide (iNO)]

Severe respiratory failure of the newborn often results in persistent pulmonary hypertension, which is characterized by increased pulmonary vascular resistance, decreased pulmonary blood flow and severe hypoxaemia. Since 3 years inhaled nitric oxide (iNO) has been used as a selective pulmonary vasodilator with variable success in the treatment of persistent pulmonary hypertension. In the present clinical pilot study 10 patients (4 newborns and 6 preterm infants) suffering from severe respiratory failure were treated with iNO. The aim of this study was to evaluate the effectiveness of inhaled NO and to discuss whether or not extracorporeal membrane oxygenation (ECMO) could be delayed or avoided. In all patients oxygenation improved without a decrease in systemic blood pressure. The median OI decreased from 41 to 16.5 during the first 4 hours of treatment and to 12 during the first 12 hours. One patient with congenital diaphragmatic hernia required ECMO therapy and died post operative. One preterm infant with primary pulmonary hypertension died during prolongated hypotension and hypoxemia. iNO may have reduced the need for ECMO which however should be available as an ultimate therapeutic option.
