About 60% of the world population has access to the Internet in 2021, making it the main tool in fostering communication between people. Lately, digital information and communication have especially taken place on platforms known as Social Media (SoMe) or Social Networks. In the last decade the usefulness of these tools in carrying information aimed at updating professionals in Medicine and Nephrology has become evident. There are several examples of SoMe utilization in Nephrology, as demonstrated by the existing accounts or Pages operated by the main international nephrological Scientific Societies, or the most renowned specialized medical journals. Twitter, Facebook and YouTube are the most versatile SoMe for these objectives; however, other platforms such as Tik Tok, Linkedin, Instagram, and WhatsApp may serve the same purpose. This digital revolution in disseminating information has proved very useful during the recent COVID-19 pandemic, even though some inappropriate uses have emerged, such as the diffusion of fake news, which has favored the emergence of "adverse effects" or a surge of antiscientific positions. In this review, we examine how physicians and nephrologists can take advantage of digital information for their continuing education. We quote the main resources in the international scenario and illustrate some specific national examples, such as the Journal Club of the Nephrology post-graduate program of the University of Milan and the Facebook group "Medical and Nephrology Community"., (Copyright by Società Italiana di Nefrologia SIN, Rome, Italy.)

Background and Aim: Over 80% (365/454) of the nation's centers participated in the Italian Society of Nephrology COVID-19 Survey. Out of 60,441 surveyed patients, 1368 were infected as of April 23rd, 2020. However, center-specific proportions showed substantial heterogeneity. We therefore undertook new analyses to identify explanatory factors, contextual effects, and decision rules for infection containment., Methods: We investigated fixed factors and contextual effects by multilevel modeling. Classification and Regression Tree (CART) analysis was used to develop decision rules., Results: Increased positivity among hemodialysis patients was predicted by center location [incidence rate ratio (IRR) 1.34, 95% confidence interval (CI) 1.20-1.51], positive healthcare workers (IRR 1.09, 95% CI 1.02-1.17), test-all policy (IRR 5.94, 95% CI 3.36-10.45), and infected proportion in the general population (IRR 1.002, 95% CI 1.001-1.003) (all p < 0.01). Conversely, lockdown duration exerted a protective effect (IRR 0.95, 95% CI 0.94-0.98) (p < 0.01). The province-contextual effects accounted for 10% of the total variability. Predictive factors for peritoneal dialysis and transplant cases were center location and infected proportion in the general population. Using recursive partitioning, we identified decision thresholds at general population incidence ≥ 229 per 100,000 and at ≥ 3 positive healthcare workers., Conclusions: Beyond fixed risk factors, shared with the general population, the increased and heterogeneous proportion of positive patients is related to the center's testing policy, the number of positive patients and healthcare workers, and to contextual effects at the province level. Nephrology centers may adopt simple decision rules to strengthen containment measures timely.

Background: Given the public health challenge represented by chronic kidney disease, the Italian Society of Nephrology (SIN) promoted a census of the renal and dialysis units to analyze structural and human resources, organizational aspects, activities and workload, referring to the year 2018. Methods: An on-line questionnaire including 60 questions, exploring structural and human resources, organizational aspects, activities and epidemiological data referred to 2018, was sent to the heads of all identified Italian renal or dialysis unit. Results: 567 renal units were identified, 3.3 public and full renal unit pmp. The nephrology beds are about 37.6 pmp. The nurses were 8,130 in HD wards, 1,827 in the nephrology wards, only 432 for outpatient clinics. Conclusions: Data from this census may be used for benchmarking and comparison between centers, regions and groups of regions. These data offer a snapshot of the clinical management of renal disease in Italy., (Copyright by Società Italiana di Nefrologia SIN, Rome, Italy.)

Methods: An on-line questionnaire including 60 questions, exploring structural and human resources, organizational aspects, activities and epidemiological data referred to 2018, was sent to the heads of all identified Italian renal or dialysis unit. Results: Renal and dialysis activity was performed by over 2,718 physicians (41 pmp). The management of the acute renal failure was one of the most relevant activities in the public renal units (3,000 pmp patients in ICU and 183.000 dialysis sessions). Italian Nephrologists performed about 6000 AV fistulas out of a total of 9300. In the survey there are a lot of data regarding organization, workforce and workload of the renal unit in Italy. Conclusions: Data from this census may be used for benchmarking and comparison between centers, regions and groups of regions. These data offer a snapshot of the clinical management of renal disease in Italy., (Copyright by Società Italiana di Nefrologia SIN, Rome, Italy.)

Nephrology continues to be in transition. While rates of kidney diseases and injury continue to rise, changes in the general health care system and the delivery of kidney care make it unclear how increases in need will be translated into demand for nephrologists. The changes in the delivery system also raise questions as to the future roles and career paths for nephrologists. There a major interrelated workforce issues to be watched closely : how many nephrologists are needed ? The supply of nephrologists does not reflect the distribution of patients with kidney diseases or the activity and job description related to end stage renal disease (ESRD) patients. Looking forward, more needs to be done to systematically measure need and access, and to identify clinical areas and activity of high need for nephrologists. This review examines the laws that govern the measure of work and the needs of personnel of the Italian state and in particular in health care. Therefore, once the method is accepted and established, it will be possible communicate those findings to policy makers and fellows and to involve the politicians., (Copyright by Società Italiana di Nefrologia SIN, Rome, Italy.)

The increasing technological effectiveness has undoubtedly produced an improvement in clinical parameters of dialysis patients, but this satisfactory therapeutic result did not follow an adequate improvement in mortality or in the perception of quality of life as per patients. Furthermore, dialysis treatment is often associated with "inapparent charges" that reduce the perception of well-being, independently of clinical changes. Thirty years ago, we carried out a national survey on inapparent charges, which represent frustrating aspects that negatively affect patients' perception of their quality of life. Thirty years later, it seemed important for us to repeat the survey to understand if Italian legislative remodeling have introduced changes in procedures and social aspects of dialysis, as preservation of quality of life is an important aspect of the replacement treatment., (Copyright by Società Italiana di Nefrologia SIN, Rome, Italy.)

Objective: The most recent literature has shown extensively that a low-protein diet in patients with chronic kidney disease (CKD) delays the natural progression of end-stage renal disease and the necessary treatment of chronic dialysis. The aim of this study was to estimate the cost-effectiveness of a very low-protein diet compared with a moderate low-protein diet., Design: Markov model., Setting: The study was conducted from the perspective of the Italian National Health Service., Subjects: Patients with CKD stages 4 and 5. Seven hundred and two patients were considered, and half were treated with a very low-protein diet and the other half with a moderate low-protein diet., Intervention: The Markov model estimates the costs and the quality-adjusted life years (QALYs) associated with a very low-protein diet versus a moderate low-protein diet for patients with CKD Stages 4 and 5. The transition probability was estimated on data from 7 studies, which determined the efficacy of very low-protein diets in delaying the need to start maintenance dialysis. Utilities and cost were estimated from literature review and projected for the lifespan considered in the model. The annual cost of dialysis per patient was approximately €34,072. The cost of a very low-protein diet was €1,440 per patient per year in the Lazio region (conservative assumptions). Probabilistic and deterministic sensitivity analyses were performed., Main Outcome Measure: QALY, cost of treatment, incremental cost-effectiveness ratio., Results: The model estimates that a very low-protein diet should be more effective. Dietary treatment improved 0.09 QALYs after 2 years, 0.16 after 3 years, 0.36 after 5 years, and up to 0.93 incremental QALYs after the first 10 years. After 2 years, the model estimated increment cost in favor of the most restrictive dietary treatment of €826, €2,146, €5,203, and €10,375 for 2, 3, 5, and 10 years of follow-up respectively., Conclusions: The results of these simulations indicate that the treatment of CKD patients with a very low-protein diet is cost-effective relative to a moderate low-protein diet in an Italian setting. Further studies should test this model in other countries with different dialysis costs and dietary support., (Copyright © 2014 National Kidney Foundation, Inc. Published by Elsevier Inc.

Nowadays a large amount of medical data are available, although they are not always homogeneous, they arise from different backgrounds and are used for different purposes. The aggregation of these data could give huge boost to the epidemiology and, in particular, to nephrology. In many parts of Italy there is the aim to reorganize the hospital health care, as well as the territorial setting. In this framework, the role of nephrology is evaluated without data to support the ongoing decisions, therefore the linkage among the data stored in the administrative and clinical databases of the Local Health Unit could contribute to the planning of nephrological (but not only) activities, in order to ensure the best cost-effectiveness possible for each different reality.

New media tools such as web 2.0 are increasingly being used in the medical field. RSS feeds, podcasts, blogs, wikis, online social networks and social media have all been proposed as innovative tools for the education and updating of clinicians, nurses, other health workers and medical students because of their ease of access and widespread use. Nephrology is one of the medical fields where these technologies have been successfully applied. Medical journals such as the American Journal Kidney Diseases and the Journal of the American Society of Nephrology, and medical societies such as the American Society of Nephrology, are all using these new and powerful communication tools. In addition, blogs and social networks have been developed to allow physicians to distribute, share and comment medical material concerning issues related to nephrology and kidney disease, including images, videos, slides, scientific abstracts and clinical trials updates. This review provides background information on the evolution of both web 2.0 and the social media and describes some of the most interesting applications of web 2.0 and its correlated tools in the field of nephrology.

Over the last years in the industrialized countries there have been many changes in the number and characteristics of patients starting renal replacement therapy. This review reports the changes that took place in Italy, analyzing the data from the Italian Registry of Dialysis and Transplantation (RIDT), which collects information from all Italian regions according to common inclusion and coding parameters. The years between 1999 and 2009 were analyzed for the calculation of the average and median age of incident patients, the percent distribution of the different diseases necessitating dialysis, and the mortality after one year. Patients who underwent a kidney transplant as the first event were not included in the analysis. The incidence of uremia in Italy showed a constant increase from 1999 (131 pmp) to 2009 (160 pmp), mainly due to an increase in patients aged over 70 years. In fact, in recent years about 50% of the patients who started renal replacement therapy were aged over 72, 25% were older than 78 years, and only 25% were younger than 60 years. According to the Italian epidemiological data, the percentage of patients with diabetic nephropathy or diabetes as comorbidity has risen steadily (from 19% in 1999 to 27% in 2009). However, in spite of the progressive increase in the two main risk factors for survival (older age and diabetes), the mortality after one year of renal replacement therapy did not show a significant rise from 1999 to 2009.

Background: Relative survival, a methodology previously used in epidemiologic studies of cancer, compares the observed survival of a patient cohort with expected survival derived from general population life tables. We examined relative survival in patients treated by long-term dialysis in the Italian Dialysis and Transplantation Registry in order to determine the prognosis of dialysis patients., Study Design: Cohort study drawn from a registry., Setting & Participants: Patients enrolled in the Italian Dialysis and Transplantation Registry., Factors: Sex, age, primary kidney disease, renal replacement therapy modality, and main comorbid conditions., Outcomes: Death from any cause., Measurements: Relative survival ratio (the ratio of observed survival in the population of interest to the survival expected given the age- and period-specific mortality of the general population) and excess mortality rate (difference between observed and expected mortality rates)., Results: In January 2000 to December 2008, a total of 27,642 patients were included. The 5-year relative survival estimate was 55.6% (95% CI, 54.7%-56.5%). The excess mortality rate showed a peak at 3 months (21 deaths/100 patient-years), then decreased, becoming constant from the end of year 1 to year 8, with leveling off at about 10 deaths/100 patient-years. Older age, systemic diseases, and diabetes showed the strongest association with excess mortality. Peritoneal dialysis was associated with a lower relative excess risk in only the first year of treatment., Limitations: The patient cohort comprises about half the Italian patients beginning dialysis therapy in the period., Conclusions: This study highlights the applicability of relative survival methods in dialysis patients. This measure allows estimation of disease prognosis and severity comparisons among chronic diseases. The excess mortality rate appears to be a more sensitive and informative measure than the simple proportion of survivors., (Copyright © 2012 National Kidney Foundation, Inc.

Background: Albuminuria is a powerful predictor of renal and cardiovascular outcomes in type 2 diabetes and a good indicator of the evolution of renal disease. Our aim was to obtain information concerning the identification of albuminuria as well as the utilization of antihypertensive, lipid-lowering and antiplatelet drugs in patients with diabetes., Methods: Subjects were enrolled from individuals registered with 3 Italian local health units by querying the drugs reimbursable, hospital laboratory investigation and hospital discharge databases. The determination of albumin to creatinine ratio (ACR) throughout 2007 and 2008 was defined as the index date. Patients who received at least 2 prescriptions of hypoglycemic drugs in the 12 months before the index date were classified as diabetics. We looked also for prescriptions of antihypertensive, lipid-lowering and antiplatelet drugs., Results: Among a population of 701,133 subjects, we identified 29,350 patients with diabetes (4.2% of the cohort). ACR had been determined in 5,644 diabetic subjects (19.2% of that cohort). The prevalence of determination of ACR in nontreated subjects was 16.0%, while in treated subjects, it ranged from 13.6% to 34.9% according to different schedules of treatment. Drugs acting on the renin-angiotensin system were prescribed in more then 80% of diabetics. The ratio of angiotensin receptor blockers to angiotensin-converting enzyme inhibitors regimen was 0.64 in subjects without determination of ACR, 0.88 in subjects with normal albuminuria, 1.02 in subjects with microalbuminuria and 1.43 in subjects with macroalbuminuria., Conclusions: Our methodology can easily be applied to obtain an epidemiological view of albuminuria and pharmacological treatments of diabetics in a general population.

This paper reports the analysis of the second part of the data obtained from the second SIN census and illustrates the management model of the Italian dialysis centers, highlighting its strengths but also its limits. The census was carried out between March and December 2008 with a webbased survey using fillable PDF forms. The survey was validated by comparing the data with those sent to the Italian Dialysis and Transplant Register (Registro Italiano di Dialisi e Trapianti, RIDT) and hence it refers to December 31, 2008, the date of the last RIDT report. Forty-two percent of dialysis centers, which altogether take care of 50% of Italian dialysis patients, participated in the census. The participation percentage was very variable among Italian regions (from 5% to 100% of dialysis centers). By excluding the three regions with a participation rate below 10%, the survey reached a participation rate of 68% of all Italian dialysis centers and is therefore sufficient to give an estimate of the Italian dialysis situation. However, because of this variability it was not possible to compare regional situations, and the data were evaluated only by analyzing the ''complex'' and ''simple'' dialysis centers separately. The state of affairs of dialysis in Italy on the whole proved to be complicated. It is striking, for example, that 15% of the ''complex'' dialysis centers do not have their own hospital beds and some of them lack traceability programs. Noteworthy are also the increasing use of central venous catheters and the number of patients that need an ambulance to get to the dialysis center. Despite its limits due to the reduced participation in the census, this work offers a fair description of the state of affairs of dialysis in Italy, where there is certainly space for qualitative improvement. First of all, however, every effort should be made to implement and improve the use of the existing structures and to standardize protocols and behaviors in all Italian dialysis centers.

This paper reports on a first analysis of data of the second survey promoted by the Italian Society of Nephrology (SIN), with particular regard to data referring to the nephrologist's workload. The survey was carried out through a Web-based questionnaire that participants could fill in online between March and December 2010. The data were validated against those of the Italian Dialysis and Transplant Registry (RIDT) and therefore refer to 31 December 2008, the date of the last RIDT report. Accurate completion of the questionnaires and reminders were monitored by the presidents of the regional sections of the SIN and the regional registries' chairpersons under the coordination of four area managers and a census committee. The response to the survey represented 42% of all nephrology centers, treating about 50% of all dialysis patients in Italy. The response percentage varied widely among regions (from 5% to 100% of the centers). After exclusion of the three regions with responses below 10%, it reached 68%, which was sufficient to give an idea of the state of nephrology in Italy. However, due to this wide variability, it was not possible to make an overall comparison of the regional situations, hence data for complex and simple structures were assessed separately. Despite the limits due to the incomplete participation in the survey, this article provides a clear description of the state of nephrology in Italy. The results confirm the hypothesis presented in the work of Bocconi Cergas, namely that the nephrology market is broader than nephrologists are able to control. The work of the nephrologist, which still seems to be focused mainly on dialysis in its various forms, should be directed more towards the development of methods for early detection of kidney disease and close follow-up. The ultimate aim is the early diagnosis of kidney disease and hence prevention of its complications, so that the focus no longer needs to be on ESKD treatment systems.

The care provided by a nephrologist is fundamental because the nephrologist is able to prevent, recognize and treat the many and complex factors of comorbidity inherent in chronic kidney disease at its various stages. The nephrologist also has the important task of delaying the start of dialysis for as long as possible. Delaying dialysis slightly, even just one year for each patient, will have ethical, social and economic advantages that should be duly weighed and carefully evaluated when adopting organizational models of care involving nephrology. The nephrologist bases his work on the clinical competence acquired and maintained through appropriate training programs based on CME courses and, above all, daily clinical practice that, in order to be truly educational, must reach a sufficient volume of activity to guarantee the best possible outcome to the patient.

This is the second part of a document describing a voluntary certification process based on Joint Commission International (JCI) criteria developed by the Italian Society of Nephrology (SIN) and JCI representatives. In the first part we discussed standards for clinical care delivery and performance measurements related to chronic kidney disease care. Herein (Part II), we complete the description of Performace measurements and CKD care by describing issues related the management and clinical information management.

The Italian research institute CENSIS recently estimated that the total monetary cost of dialysis in Italy reached almost 2,700 billion old lira (about 1.4 billion euros), with more than a quarter of that as social costs largely borne by families. The yearly cost in Italy for acetate and bicarbonate dialysis has been estimated at Euro 35,000 per patient and is steadily rising. Delaying renal death and start of dialysis by an average of two years is one of the most relevant ''monetary'' benefits of low-protein diets, even more so when considering that about half of all elderly patients starting dialytic treatment will die within three years. Reduced intake of phosphorus is another benefit of low-protein therapies that is associated with substantial monetary savings, thanks to a reduced need for phosphate-binding agents. Highly palatable preparations of low-protein content are already available, and are probably already self-paying if the savings from reduced prescription of phosphate binders are accounted for.

In the last few years the Italian Society of Nephrology has addressed many technical-scientific and management aspects to better patient satisfaction. Project No. 1 of the 2004-2006 programme on 'Quality and Accreditation of National Renal Units' focuses on four essential points. The first is the questionnaire mailed to all the Presidents and Regional Delegates on the relationship between Nephrology units, Local Government Health-System and the Regional Healthcare Agency. The results evidence that the 'political' decision-making power of nephrologists decreases in the absence of a national strategy. The second point, in collaboration with the National Census Group, includes the quality analysis and the standardization of resources (human and structural) and management of the Renal Units. The third point is based on 'Educational Courses for Quality and Accreditation' held in Rome (3-5 October 2005: L'Accreditamento all'Eccellenza dell'Unita' Operativa di Nefrologia, Dialisi e Trapianto; 17-19 October 2005: Il Manuale di Accreditamento della Specialità di Nefrologia). The courses aim at training members responsible for each region to hold courses in their specific region to create a network including each single Renal Unit to create an acceptable homogenous language on the models of analysis and on the correct use of 'The Guide for Excellence Accreditation'. The fourth point concerns both the on-line Guide for Excellence Accreditation and 'Peer Review Accreditation' and the NEQUASY (Nephrology Quality System) project. The manual must be 'user friendly' allowing each Centre to self-evaluate using national and regional standards.

The Italian Society of Nephrology (SIN) promoted a national survey in order to collect detailed information from all Italian renal and dialysis units. This is the second paper, following the first one which focused on three northwestern regions, aim-ing to present the results of the survey. In this paper, data from the central regions (Abruzzo, Lazio, Marche, Molise and Umbria) are reported. The most relevant findings in the five regions were: A) epidemiology--prevalence of dialysis patients = 742, 781, 731, 814, 768 per million population (pmp); prevalence of transplanted patients = 162, 153, 296, 134, 304 pmp; incidence of dialysis patients = 175, 179, 184, 143, 162; gross mortality of dialysis patients = 12.3, 11.8, 15.9, 13.4, 14.0%; distribution of vascular access in prevalent dialysis patients: arteriovenous fistula = 90, 87, 82, 94, 80%, central venous catheter = 7, 10, 15, 4, 17%; vascular graft = 3, 3 ,3, 2, 3%. B) Structural resources--number of hospital beds = 52, 43, 39, 62, 44; dialysis places = 205, 260, 203, 301, 226. C) Personal resources--renal physicians = 50, 78, 47, 53, 47 pmp; renal nurses = 162, 172, 180, 224, 245 pmp; each renal physician takes care of 15, 10, 16, 15, 17 dialysis patients and each renal nurse cares of 4.6, 4.6, 4.1, 3.6, 3.1 dialysis patients. D) Activity--admission to hospital= 2334, 1689, 2652, 1255, 1377 pmp; renal biopsies = 59, 84, 97, 19, 80 pmp. Despite the differences we find among the regions, most indexes are similar and show a satisfactory level of renal care provided in the central regions examined.

As managed care relevance is growing, several old issues related to personal institutional responsibility are increasing among practitioners. Therefore, as a professional figure a nurse bases his/her job on a mix of personal knowledge and skills along with training, and he/she is responsible for giving advice in line with professional care standards. In addition, he/she is in charge of the treatment pattern agreed with the patient. However, nursing is a much more complex job, which leads professional figures facing the controversial issue of combining institutional responsibility and nursing professional tasks and duties daily. As far as nursing institutional responsibility is concerned, different view points or approaches can be applied to investigate it. The most common one is the legal approach, yet this is not the most appropriate one. Therefore, our professional background is mainly based on a management prospective rather than a legal one; dealing with the issue legally would lead, essentially, to a summary of laws and regulations without any kind of argumentative discussion. Consequently, this study aimed to analyze nurses' institutional responsibility by approaching the issue from an innovative human resources management prospective; therefore, defining the gap between nursing institutional responsibility and its tasks.

The Italian Registry of Dialysis and Transplantation (RIDT) was born in 1996 under the aegis of the Italian Society of Nephrology, and it is organized as a federation of regional registries. This study aimed to completely revise the epidemiological data collected during the first 5 yrs (1996-2001) of RIDT activity to evaluate the trends of the main epidemiological features. During this period, regional registries were not always able to assure complete and exhaustive information according to RIDT requirements, owing to different levels of organization and functioning. To avoid any possible error in data analysis, information inadequately assessed was refused. The incidence of end-stage renal disease (ESRD) patients on renal replacement therapy (RRT) in Italy has increased from 114 pmp in 1996 to 139 pmp in 2001, that means an increase of 3.5%/yr, corresponding to 5718 patients during 1996 and 8000 patients during 2001. Primary renal diseases (according to the EDTA) in incident ESRD patients are vascular and diabetic nephropathy. Main dialysis modality in incident patients was hemodialysis (HD) (85%), while peritoneal dialysis (PD) was only 15%; pre-emptive transplantation was a very unusual modality. The prevalence of ESRD patients at 31 December was 693 pmp in 1996 and 827 pmp in 2001; among dialysis patients, the corresponding rates were 575 pmp and 657 pmp, respectively. Consequently, the number of dialyzed patients increased, respectively, from 28892 to 37919. The prevalent dialysis modality was bicarbonate dialysis in 74% of cases, followed by hemodiafiltration (HDF) in 15%, continuous ambulatory peritoneal dialysis (CAPD) in 7% and APD in 3%. The gross mortality rate in dialyzed patients was stable during this period, at approximately 14%, the main causes of death being cardiovascular diseases and cachexia.

Like many specialized branches of medicine, the future of nephrology will be entrusted to organizational models that are able to withstand the impact of both the new and increasing demand for assistance and the rationalization of resources. Therefore, it is necessary to clearly understand that the model must integrate and unify many aspects that regulate the activities in the health care service. Budget means "who does what and with material and what human resources" with respect to the constraints imposed by the decisions of the controlling entities, and it is mainly a system of planning and control. Management control utilizes a combined and coordinated synthesis of various company techniques including an auditing system, analytical accounting (or per cents of cost), a reporting system able to change the data gathered into measures of syntheses that can be used to carry out sound evaluations. The health system needs a type of organization--typical of professional organizations--that is an absolute prerogative of the technical/professional component which is the only one able to discern, understand and propose new diagnostic and therapeutic trends and approaches. At the end an evaluation of quality system is depicted. ISO 9004 norms, for example, provide principles on which an organization must be based, in order to reach high levels of quality and that must be used by the top management to lead the organization towards improved performance.

The process of institutional accreditation has been initiated in Italy too because it is considered to be the criterion upon which new relations within the National Health Service must be based. These relations include payment for the service as well as choice of quality assessment and revision of the activities carried out and the services provided. This paper describes the regulations in force regarding Institutional accreditation and the specific regulations of Italian regional credit laws on nephrology. The Regions examined are Lazio, Campania, Marche, Basilicata and Lombardy. A synoptic table showing the most important criteria, differentiated according to each region, is also included.

The economic approach of the industrial and commercial sector cannot be transferred to the medical one without proper measures. The final objective of the health service is not to gain profits but rather to achieve results in terms of health. Professional quality and, therefore, appropriateness becomes the foundation for proper management. In turn, appropriateness means to do the right things when they are useful regarding both the organisational, administrative, educational and training aspects and the medical ones. Management control is the right answer to this challenge to know and monitor consumption, strategies and results in relation to preestablished administration health policy objectives. Its purpose is to allow the organisation to carry out its objectives with the highest effectiveness and efficiency possible and it is joined with technical-professional elements which orient and support management in a logic of total quality. The adoption of the process of management control does not mean to turn doctors into managers. It must be hoped that doctors will understand the economic implications of the decisions made at clinical level as well as the technical-organisational ones. A medical action becomes effective if it is part of a system in which each person involved carries out his duties in an integrated logic where relationships are clearly defined. To decide what is appropriate, one refers to what is known and proven. It is clear that the problem of quality must be faced firmly and systematically. The activation of a quality program is not only based on the definition of "good practice", in terms of procedures, protocols, pathways and reference parameters for measuring quality but rather on the introduction of clinical methods that can guarantee a series of highly important opportunities.

The epidemiology of non-A, non-B hepatitis (NANBH) is still incomplete. To define the prevalence of antibodies against the main causative agent of NANBH, the hepatitis C virus (HCV) and the role of some risk factors, we tested sera from 269 patients on chronic dialysis at the hemodialysis units in our region in central Italy. We utilized the recently developed serological assay. Twenty-nine hemodialysis patients (13.3%) and 3 peritoneal dialysis patients (4.8%) were anti-HCV positive. Of these, 13 (40.6%) had antibodies to hepatitis B core antigen (anti-HBc) indicating prior hepatitis B infection. The anti-HCV seropositive patients had been on dialysis longer than the seronegative ones; they had received more transfusions than the others but without a significant difference. The prevalence rate of anti-HCV was statistically significantly higher among hemodialysis patients utilizing the same dialysis equipment for the previous 12 months.
