Resource utilization and direct costs of pediatric HIV in Italy

This multicenter, prospective, observational study assessed the global economic impact of HIV care in a large cohort of HIV-infected children and adolescents in Italy. Three pediatric departments of reference participated on a voluntary basis. Centers were asked to enroll all their children during the period April 2010-March 2011. At enrollment, a pediatrician completed a questionnaire for each patient, including the type of service at access (outpatient consultation or day hospital), laboratory tests, instrumental examinations, specialists' consultations, antiretroviral therapy and opportunistic illness prophylaxis. Eligible patients had a confirmed diagnosis of HIV infection caused by direct vertical maternal-fetal transmission, their age ranging from 0 to 24 years. Since patients routinely have quarterly check-ups in all three centers, we adopted a three-month time horizon. Health-care services were priced using outpatient and inpatient tariffs. Drug costs were calculated by multiplying the daily dose by the public price for each active ingredient. A total of 142 patients were enrolled. More than half the patients were female and the mean age was 14 years, with no significant differences by center. There were substantial differences in health-care management among the three centers, particularly as regards the type of access. One center enrolled the majority of its patients in day-hospital and prescribed a large number of clinical tests, while children accessed another center almost exclusively through outpatient consultation. Drug therapy was the main cost component and was very similar in all three centers. The day-hospital was the second highest cost component, much higher than outpatient consultation (including examinations), leading to significant differences between total costs per center. These findings suggest that a recommendation to the Italian National Health Service would be to use more outpatient consultation for patients' access in order to increase their efficiency in treating pediatric HIV infection.

The burden of moderate to severe psoriasis: an overview

Psoriasis is a chronic, immune-mediated skin disorder that affects 1-3% of the general population worldwide. While considered a non-life-threatening disease, psoriasis represents a social and financial burden for patients and the healthcare system. Individuals suffer from disfigurement and from social stigmatization. Because the disease is usually persistent, patients with a diagnosis of psoriasis usually need lifelong care, which also means a lifetime of expenses. We aimed to conduct a comprehensive review of the evidence available concerning the social burden and costs of psoriasis. A search for the keywords 'quality of life' (QOL) or 'burden' or 'stigmatization' or 'psychological factors' in PubMed up to January 2010 yielded a total of 817 studies. QOL was affected by psoriasis to a degree comparable with diabetes or cancer. A search for 'cost-of-illness analyses', in the same period, yielded only seven papers satisfying entry criteria. All the studies but one were performed before biologics became available for psoriasis treatment. Direct costs were higher than indirect costs, with hospitalization representing the most significant item. Treatment costs showed wide variations between different studies. Reasons for these discrepancies are manifold including differences in the selection of the sample, as well as in the methods for calculating costs. There is a need to harmonize methodologies. For a final conclusive judgement of the cost effectiveness of innovative therapies such as biological agents, long-term economic consequences have to be evaluated and long-term remission rates and complications considered.

Health status, resource consumption, and costs of dysthymic patients in Italian primary care

Aims – To describe the health status, resource consumption and costs of patients with dysthymic disorder in the Italian primary care setting. Methods – A total of 79 general practitioners (GPs) participated the study. Diagnosis was based on each GP's clinical assessment. At entry the Mini-International Neuropsychiatric Interview (MINI) was used as a supporting diag- nostic aid. Health status was measured with the SF-36 questionnaire. Resource consumption and costs regarded the six months before enrolment. Results – Out of 598 patients enrolled by GPs according to their clinical assessment, 503 fulfilled the MINI cri- teria and 95 did not. The latter had a better perception of their health than the former. Resource consumption was similar in the two groups; and the total per patient six-month costs did not differ significantly. Conclusions – The study confirms there may be a gap between standardised criteria for defining dysthymia and everyday clinical practice. All dysthymic patients diagnosed by GPs might be considered together from a health policy perspective.

Declaration of Interest: this research was partly supported by a contribution from Sanofi-Synthelabo Italy.

Healthcare costs of multiple myeloma: an Italian study

Few economic evaluations are currently available on multiple myeloma (MM) and they address treatment-related rather than disease-related costs. We estimated resource utilisation and costs associated with MM in an Italian haematology department. This was a single-centre observational study which followed retrospectively for 2 years 90 patients with MM stages II-III. To investigate the association between costs and age as a prognostic factor for treatment eligibility, patients were classified in two age groups (under 65 or >65). The annual average cost per patient was very similar in the two subgroups. Drugs and hospitalisations were the largest cost components. Differences between the two age groups were significant only for drugs, hospital admissions and day hospital (DH) days. Autologous stem-cell transplantation (ASCT) accounted for more than 80% of the non-pharmacological therapy costs, being nearly double in the younger patients. Cost of elderly patients is comparable with that of younger ones who generally receive expensive procedures such as ASCT. The higher hospital costs of younger patients were counterbalanced by supportive pharmaceutical care and DH days for older patients, mainly in the group treated with new immunomodulatory agents. Further multi-centre studies on larger samples of patients are needed.

Economic evaluation of human papilloma virus vaccination in the European Union: a critical review

The human papilloma virus (HPV) vaccine is a new and expensive vaccine potentially effective in the prevention of a cancer. We reviewed the economic evaluations (EEs) on the vaccine in the EU to assess their potential contribution to public decision-making in a fairly homogeneous setting where HPV vaccination has been widely adopted. A literature search on PubMed selected EEs on HPV vaccines in the EU for the period 2007-2010 using the terms "HPV vaccines" and "Costs and cost analysis." Fifteen articles were eventually selected. All studies were based on modelling techniques, either "cohort" or "dynamic transmission": three were cost utility, three cost-effectiveness, and the remainder included both. The ten studies explicitly assessing one of the two vaccines were all sponsored by their manufacturer, while the five studies unrelated to the vaccine type were funded by public agencies. Apart from two studies, utility estimates were always obtained from three US sources. Direct costs were always vaccination, diagnosis and treatment of related pathologies. Incremental cost-effectiveness ratio (ICER) results were less favourable when life years gained were valued rather than quality-adjusted life years, genital warts were excluded, and booster doses and extension of vaccination to men were included in the base-case analysis. All but one of the sponsored EEs recommend in favour of the vaccination strategy, which is dominant in one English study. The ICER results were very sensitive to discount rates, followed by duration of protection and vaccine price. At such an early stage, when the vaccines' efficacy have been demonstrated by well-designed studies, it is not possible (and not even reasonable) to wait for several years to measure their effectiveness; public decision-makers might benefit more from EEs designed to indicate sustainable prices using realistic estimates of crucial variables like coverage rates, rather than referring to a large number of assumptions in order to show acceptable cost-effectiveness.

Management of vaccinations in Italy: a national survey after healthcare regionalization

OBJECTIVES

The main aim of this study was to describe the effects of regional organization and performance in managing vaccinations, in the light of the institutional devolution recently introduced in Italy.

METHODS

We analysed (1) the general organization of regions for vaccination programmes, (2) the management of four vaccination programmes (combined measles-rubella-parotitis, varicella for children, influenza, and pneumococcal 23-valent for adults). First, we conducted preliminary face-to-face interviews with 16 regional managers of the infective disease prevention departments. Subsequently, we sent them a standardized questionnaire to obtain comparable information on general organization and on the four specific vaccination programmes considered. In all, 14 regions were eventually included.

RESULTS

The survey showed a widespread lack of regional staff involved in the management of vaccinations and a geographical variation in the availability of computerized data collection. We recorded poor coverage for varicella and pneumococcal 23-valent vaccinations compared to MRP and influenza. Prices of the four vaccines varied widely among regions, with only a weak correlation between prices and volumes.

LIMITATIONS AND CONCLUSIONS

The major limitation of the survey was the lack of information available at regional level. The piecemeal diffusion of computerized systems and the widespread lack of sufficient staff should mainly explain this. Economic incentives could be offered to regions that achieve national targets. Such incentives should encourage collaboration between central and regional authorities consistent with institutional trends in regional devolution.

Influenza vaccine for healthy adult workers: an issue for health authorities or employers?

OBJECTIVE

To contribute to the debate whether extending public coverage of influenza vaccination to healthy workers is cost-effective, particularly in the perspective of EU countries.

METHODS

First, we reviewed the recent international literature on the extension of vaccination to subjects aged 50-64 years in highly developed countries. Second, we estimated the broad economic impact of influenza vaccination on the Italian healthy adult working population. Finally, we ran a pilot observational study to assess the healthcare and labour outcomes of influenza vaccination on the employees of our organization.

RESULTS

The methodological weaknesses of the studies reviewed, all built on models, undermine the credibility of their optimistic results. The more cautious the model design, the less favourable the final results, as our conservative analysis on the Italian setting confirmed. The only common result was a steady relationship between potential vaccination benefits and indirect costs of absenteeism from work. This "modelling-based evidence" was confirmed by our internal survey: vaccinated workers showed less tendency to stay at home during influenza-like illness episodes and their relapses.

CONCLUSIONS

The economic advantage of extending public influenza vaccination to healthy adult workers is still uncertain and mainly relates to the indirect costs of productivity losses, making the extension strategy more a labour than a health issue.

Continuing Medical Education in six European countries: a comparative analysis

OBJECTIVE

We examined Continuing Medical Education (CME) systems in a sample of six EU countries: Austria, Belgium, France, Italy, Norway, and the UK. The aim of this comparative study was to assess the main country-specific institutional settings applied by governments.

METHODS

A common scheme of analysis was applied to investigate the following variables: (i) CME institutional framework; (ii) benefits and/or penalties to participants; (iii) types of CME activities and system of credits; (iv) accreditation of CME providers and events; (v) CME funding and sponsorship. The analysis involved reviewing the literature on CME policy and interviewing a selected panel of local experts in each country (at least one public manager, one representative of medical associations and one pharmaceutical manager).

RESULTS

CME is formally compulsory in Austria, France, Italy and the UK, although no sanctions are enforced against non-compliant physicians in practice. The only two countries that offer financial incentives to enhance CME participation are Belgium and Norway, although limited to specific categories of physicians. Formal accreditation of CME providers is required in Austria, France and Italy, while in the other three countries accreditation is focused on activities. Private sponsorship is allowed in all countries but Norway, although within certain limits.

CONCLUSIONS

This comparative exercise provides an overview of the CME policies adopted by six EU countries to regulate both demand and supply. The substantial variability in the organization and accreditation of schemes indicates that much could be done to improve effectiveness. Although further analysis is needed to assess the results of these policies in practice, lessons drawn from this study may help clarify the weaknesses and strengths of single domestic policies in the perspective of pan-European CME harmonization.

Utilization and costs of antiepileptic drugs in the elderly: still an unsolved issue

The aging of the general population in industrialized countries has brought to public attention the increasing incidence of age- and aging-related clinical conditions. Management of multiple and chronic disorders has become a more important issue for healthcare authorities because of increasing requests for medical assistance, the greater numbers of drugs required and drug interactions reported, and the increase in treatment-related costs. Epilepsy is a chronic clinical condition affecting both sexes and all ages with a worldwide distribution. The incidence of epilepsy, after childhood, increases with age and the cumulative risk of epilepsy by 80 years of age ranges from 1.3% to 4% in different study populations. Although the issues for people with epilepsy are similar for older and younger adults, the elderly may require more attention with regard to selection of antiepileptic drugs (AEDs) than younger patients. Elderly patients with newly diagnosed epilepsy are more likely to remain seizure-free on AED therapy than younger populations; however, the toxicity of AEDs in elderly patients is ill-defined because seizures may be difficult to recognize in this group and the symptoms and signs of toxicity can be attributed to other causes. Moreover, elderly people have chronic clinical conditions and are more likely to be taking medications that could possibly interfere with AEDs.Some older AEDs such as phenobarbital and phenytoin should not be used in the elderly because of their pharmacokinetic and pharmacodynamic profiles. There is no evidence that new AEDs, despite their better tolerability profiles, are advantageous in terms of attaining freedom from seizures compared with older agents.Older AEDs are much less expensive than the new compounds and, with some exceptions, appear to be more cost effective. New AEDs may be cost effective only in patients who are not able to tolerate or who are resistant to older compounds or when the use of an older drug is contraindicated. However, there are no cost-effectiveness studies in the elderly and further evidence is needed to confirm these assumptions.

Economic analysis of newer antiepileptic drugs

In the last 20 years, several second-generation antiepileptic drugs (AEDs) have been marketed. These newer drugs are expensive and have no established superiority over the first-generation compounds in terms of efficacy when used as monotherapy. A systematic review of economic studies dealing with the newer AEDs has been performed to put these drugs in a wider perspective. A number of economic analysis studies of second-generation AEDs have examined these compounds as monotherapy or adjunctive therapy. Almost all monotherapy studies showed newer AEDs as having similar effectiveness but significantly higher acquisition costs than first-generation drugs. The evidence from adjunctive therapy studies was more conflicting. Lamotrigine appeared to be a cost-effective drug when higher thresholds were used, or when savings were defined by the cost of surgery. Levetiracetam also appeared to be cost effective when the costs of surgical investigation were discounted.In a decision model that included quantification of the uncertainty associated with the decision regarding the cost effectiveness of AEDs, second-generation drugs used as monotherapy for newly diagnosed partial epilepsy produced similar benefits but were more expensive than older drugs. The newer AEDs were more effective but more expensive than existing monotherapies in patients with refractory partial epilepsy, but may be cost effective at higher thresholds, and continue to be cost effective in patients responding to the assigned drug. In patients with newly diagnosed generalized epilepsy, valproate was more cost effective than lamotrigine.The results of current economic studies are difficult to assess and compare because of a number of methodological drawbacks. Future studies should be implemented using a standardized approach to define the costs and outcomes of representative cohorts of patients with newly diagnosed epilepsy recruited from different countries and followed prospectively.

A critical review of the full economic evaluations of pharmacological treatments for glaucoma

OBJECTIVE

This literature review aimed to critically assess the 'state of the art' of the full economic evaluations (FEEs) on glaucoma pharmacological treatments. This is the first review that tries to thoroughly assess both costs and consequences of pharmacoeconomic evaluations on glaucoma.

METHODS

A literature search was done on the international databases PubMed and EMBASE, to find all the studies published in English on pharmacological treatments for glaucoma in the period 1997-2006. An economic and a clinical checklist were adopted to analyse FEEs and their clinical sources (CS). Finally, the reliability of the 33 FEEs included in the 15 articles selected was assessed from the health authorities' perspective by applying a critical appraisal checklist of 16 items derived from the economic and clinical variables previously analysed.

RESULTS

The major weakness of the articles reviewed seemed to be the extensive recourse to expert panel opinions and assumptions at each phase of the economic analysis. About one-third of the FEEs even based their clinical efficacy on non-evidence-based sources. The critical appraisal of the CS methodological characteristics showed that their quality was not high either.

CONCLUSION

This review showed that most FEEs on glaucoma suffer substantial methodological limits, mainly due to the scarce quality of available CSs, so public authorities should consider their results very cautiously for healthcare decision making.

A critical review of the full economic evaluations of pharmacological treatments for colorectal cancer

OBJECTIVE

This literature review makes a critical assessment of the methodology of the full economic evaluations (FEEs) conducted on colorectal cancer (CRC) pharmacological treatments.

METHOD

A literature search of the international databases PubMed and EMBASE was carried out to find all the studies published in the English language on pharmacological treatments for CRC in the period 2001-2005. A checklist was adopted to analyse the 13 FEEs selected. Fourteen clinical trials were extracted from the references as sources of efficacy data and were reviewed separately according to a clinical checklist. Finally, the reliability of the 13 FEEs was assessed from the health authorities' perspective by applying a critical appraisal checklist of 16 items derived from the economic and clinical variables previously analysed.

RESULTS

This review found that pharmacoeconomic studies on CRC showed important methodological weaknesses mainly regarding economic evaluation, whilst the sources of clinical evidence were of higher technical quality, although the clinical effectiveness of therapies was not fully sustained by their results.

Cost minimisation analysis of 12 or 24 weeks of peginterferon alfa-2b + ribavirin for hepatitis C virus

BACKGROUND

Pegylated interferon and ribavirin are at present the standard treatment for chronic hepatitis C virus (HCV) patients.

OBJECTIVE

The present economic evaluation compared 12 vs. 24 weeks of peginterferon alfa-2b + ribavirin treatments for HCV genotypes 2 or 3. Shortening the period of antiviral therapy is important in terms of adverse events and costs.

METHODS

Clinical evidence was based on the results of a multicentre, randomised controlled clinical trial (RCCT) conducted in Italy, which found that the shorter course of therapy was as effective as the 24-week course for patients with HCV genotypes 2 or 3 responding to treatment at 4 weeks. A cost minimisation analysis was performed. The analysis took the Italian National Health Service (INHS) point of view, thus only healthcare costs (drugs, medical consultations, diagnostic tests, hospital admissions) were considered. Healthcare activities were estimated by the RCCT principal investigators and were priced by applying the INHS tariffs and prices.

RESULTS

The total mean cost per patient was estimated at euro9,785 for the standard group and euro7,508 for the variable-duration group. Sensitivity analysis confirmed the robustness of the baseline results.

CONCLUSIONS

This study showed that the variable-duration regimen can be recommended as an efficient use of resources for patients from the INHS perspective.

Medical costs of glaucoma and ocular hypertension in Italian referral centres: a prospective study

AIM

This study analyzes the resource utilization and costs of ocular hypertension and glaucoma (staged by severity) in Italian ophthalmology departments.

METHODS

The project was a multi-centre observational study conducted in 17 Italian ophthalmology departments throughout the country. A total of 659 patients were recruited and followed prospectively for 1 year. For the purpose of analysis, the patients were divided into 3 groups according to the severity at onset: ocular hypertension, glaucoma and advanced glaucoma.

RESULTS

The subgroups differed significantly in the main demographic and clinical variables. As expected, greater severity was associated with older mean age and worse visual acuity, and with higher resource consumption and costs. The annual average cost per patient was EUR 788.7 and rose significantly with disease severity (EUR 572.0 for ocular hypertension, EUR 734.3 for glaucoma and EUR 1,054.9 for advanced glaucoma). Drugs and specialist consultations were by far the largest cost components.

CONCLUSIONS

This study offers some information on the medical costs of glaucoma in Italy potentially useful for decision-making in the health care services. Health care resources and costs increased with disease severity.

Healthcare costs of COPD in Italian referral centres: A prospective study

BACKGROUND

This study estimated the healthcare resource utilisation and costs of chronic obstructive pulmonary disease (COPD) patients, staged by severity, in the Italian pneumology departments (PDs).

METHODS

The project was a multi-centre observational study conducted in 11 Italian PDs throughout the country. A total of 268 patients were recruited and followed prospectively for 1 year. For the purpose of analysis, patients were divided into four groups according to the severity at onset: mild COPD (stage I)-postbronchodilator FEV1/FVC <70% and FEV1 >or=80% of predicted; moderate COPD (stage II)-postbronchodilator FEV1/FVC <70% and 50% <or=FEV1< 80% of predicted; severe COPD (stage III)-postbronchodilator FEV1/FVC <70% and 30% <or=FEV1 <50% of predicted; very severe COPD (stage IV)-postbronchodilator FEV1/FVC <70% and FEV1 <30% of predicted, or clinical signs of either respiratory or cardiac failure.

RESULTS

Subgroups differed significantly in the main demographic and clinical variables. Broadly, higher severity was associated with older age, longer disease duration, and more frequent exacerbations. Patients with severe COPD used more resources for almost all services than those with mild and moderate forms. The annual average cost per patient was 3040.2 euros (1046.7 euros for mild, 2319.0 euros for moderate, 3572.1 euros for severe and 5033.3 euros for very severe forms).

CONCLUSIONS

This study offers some information on the healthcare costs of COPD induced by PDs in Italy, potentially useful for decision-making in the health care services. Resources and costs rose significantly with disease severity.

Pharmacoeconomic studies in Italy: a critical review of the literature

To assess the state of pharmacoeconomics in Italy we reviewed all the original studies published by Italian authors in national and international journals from January 1994 to December 2003. We selected 70 articles and broadly assessed 92 economic evaluations (EEs) since some articles contained multiple analyses. We adopted common analysis criteria to allow methodological comparison of the studies. The variables investigated can be grouped into three categories: general methods, costs, and consequences. To further assess the quality of the EEs, we decided to rank them according to criteria of both clinical and economic good practice. Then, to complete our critical evaluation, we analysed whether sponsorship might have somehow affected the results. Our analysis seems to support the widespread scepticism of the Italian NHS decision-makers towards pharmacoeconomic studies, whose results seem to be biased by flawed methods and sponsors' interference with results.

Medical costs of chronic musculoskeletal pain in Italy

BACKGROUND AND OBJECTIVES

Musculoskeletal system problems are responsible for more than two-thirds of painful conditions in primary care. However, only one published study, conducted in Finland, has analysed the costs of managing musculoskeletal pain as a whole in primary care. This study analysed the costs of diagnosing and treating chronic musculoskeletal pain in primary care in Italy. A secondary aim of the study was to assess the impact of different drug treatment patterns on medical costs associated with musculoskeletal pain.

METHODS

Chronic pain of musculoskeletal origin was defined as continuous or recurrent pain persisting over 3 months with involvement of the musculoskeletal system, i.e. arising from primary musculoskeletal disorders or from the late consequences of external events (injuries, medical care or surgery). A total of 52 general practitioners (GPs) recruited 581 patients. We focussed on the differences between patients treated (410) and not treated (171) with drugs. Within the treated group, we also analysed subgroups given non-selective NSAID-based therapy (subgroup A, 169 patients) or cyclo-oxygenase-2 (COX-2) inhibitor-based therapy (subgroup B, 52 patients).

RESULTS

The annual average cost of treating a patient with chronic musculoskeletal pain was euro 212.60. Hospital admissions and GP consultations were the largest cost components, both accounting for around a quarter of the total cost. Not surprisingly, the treated group included older patients, who had more co-morbidities and more severe pain. This was associated with annual costs more than four times those of untreated patients (euro 274.50 vs euro 63.90, respectively). Subgroups A and B did not differ with respect to major demographic and clinical variables except in relation to mean age (63 vs 70 years, respectively; p=0.037). They had similar per-patient costs (euro 186.20 vs euro 172.90), although these totals comprised a different mix of components.

CONCLUSION

The analysis showed that the annual average cost of treatment of chronic musculoskeletal pain in Italy varied considerably depending on whether drug treatment was used. COX-2 inhibitors and traditional NSAIDs had similar per-patient costs, although this similarity stemmed from a different mix of components.

Quality of vision: A consensus building initiative for a new ophthalmologic concept

PURPOSE

Many studies have addressed the quantification of visual acuity, and the conventional method of measuring it has so far demonstrated serious limitations. Vision testing requires new methods that can more precisely express the quality of vision as perceived by the patient.

METHODS

This study employed the Delphi method of consensus building. Concepts associated with quality of vision (QoV) were identified by a board of experts and proposed to participating specialists in two subsequent questionnaires. Upon receipt of the completed questionnaires, the replies were classified to determine the building blocks of a consensus.

RESULTS

By analyzing the replies to the two questionnaires, the authors determined the key elements of QoV on which a consensus was found among the respondents.

CONCLUSIONS

A consensus was reached on the opinion that the quantification of visual acuity by traditional means is inadequate for investigating QoV. Although visual acuity is still a basic element for testing, the experts believe that contrast sensitivity, reading speed, and microperimetry are additional parameters necessary for quantifying QoV. The use of a psychometric questionnaire on visual function could allow a better interpretation of visual impairment.

Pricing and reimbursement of in-patent drugs in seven European countries: a comparative analysis

The main objective of this comparative analysis was to assess regulations applied by EU governments to reward potentially innovative drugs. We focused on the pharmaceutical policy for in-patent drugs in seven EU countries: Belgium, France, Germany, Italy, the Netherlands, Spain, and the UK. A common scheme was applied to all seven countries: first, pricing and reimbursement procedures for new and innovative drugs were investigated; secondly, we focused on the use in the regulatory process of economic evaluations. The analysis involved reviewing the literature and interviewing a selected panel of local experts in each country. According to our comparative analysis, a first sensible step might be to classify active ingredients as those addressing neglected pathologies and those for diseases that are already successfully treated, thus offering more limited therapeutic gains by definition. A reasonable solution to reward real innovation could be to admit a premium price for very innovative drugs according to their estimated cost-effectiveness. New drugs with modest improvement could be grouped in therapeutic clusters and submitted to a common reference price, despite patent expiration. Such a "dual approach" could be a sensible compromise to restrict pharmaceutical expenditure while at the same time rewarding companies that invest in high-risk basic research.

Off-patent drugs in Italy. A short-sighted view?

The new Italian policy to off-patent products, although similar to recent reforms in other European countries, seems to use some interesting instruments and has achieved significant results in the past 2 years. In particular, the prices of branded products have been reduced for all active ingredients where a generic version is available. However, this strategy may raise some problems in the longer term. Our analysis identified two open issues that might limit the long-term sustainability of the present scheme: the limited diffusion of generics and the reallocation of demand. The first stems from the new regulatory schemes which equate generics to branded off-patent products and exploit their presence only to cut prices. The second is favored by tough price competition that induces large companies to divert demand towards more profitable "me-too drugs." Solutions exist, but they are not easy to apply because so many difficulties arise when certain aspects of a long-standing equilibrium are modified.

Health status, resource consumption, and costs of dysthymia. A multi-center two-year longitudinal study

BACKGROUND

In this study we estimated the health status, resource consumption and costs of a large cohort of patients with early and late-onset dysthymia.

METHODS

The DYSCO (DYSthymia COsts) project is a multi-center observational study which prospectively followed for two years a randomly chosen sample of patients with dysthymia in the Italian primary health care system.

RESULTS

A total of 501 patients were followed for two years; 81% had early-onset dysthymic disorder. During the study, improvement was seen in most domains of the 36-Item Short Form Health Survey (SF-36) questionnaire. Comparison of the SF-36 scores for the two groups showed that only the physical health index significantly differed during the two years. The use of outpatient consultations, laboratory tests and diagnostic procedures was similar in the two groups, but patients with early-onset dysthymia were admitted significantly more than late-onset cases. Hospital admissions were almost entirely responsible for the higher total cost per patient per year of early-onset dysthymia.

LIMITATIONS

A first limitation of this study is that general practitioners were selected on the basis of their willingness to participate, not at random; secondly, no information was collected on concomitant psychiatric comorbidities.

CONCLUSIONS

The present study provides the first prospective, long-term data on service use and costs in patients with dysthymia. Differently from patients with early-onset dysthymia, patients with late-onset dysthymia were admitted less and cost less.

Pain in primary care: an Italian survey

BACKGROUND

Pain is a universal symptom of various pathologies and largely affects human well-being. Pain is therefore commonly observed by general practitioners (GPs) and its management is a useful indicator of quality. In our study we investigated the epidemiology and management of pain in Italian general practice.

METHODS

Participating GPs were asked to record the first out of every two contacts with pain during two working weeks between November 2000 and February 2001. They entered information on type of pain, pain-related diagnosis, certainty of diagnosis and types of prescription.

RESULTS

89 GPs participated in the study. About one third of all reported contacts were with pain. The number of contacts analysed was 1432. Nearly half the cases were diagnosed as acute. The main complaints were of musculoskeletal and abdominal origin. Pain was 1.5 times more frequent in women than men and the female to male ratios for acute and chronic pain were 1.2:1 and 1.8:1 respectively. The most frequent site of pain was the limbs. 'Arthropathies and related disorders', 'dorsopathies' and 'rheumatism excluding the back' were the commonest groups of diagnoses. Approximately two thirds of contacts with pain led to a drug prescription.

CONCLUSIONS

The study identified a high proportion of contacts with pain in Italian general practice, with widespread use of drugs. The distribution of chronic and acute pain was rather similar and musculoskeletal pain was the most frequent form. Most types of prescriptions were closely related to certainty of diagnosis.

Pharmaceutical policy in Italy: towards a structural change?

Italian pharmaceutical policy has recently moved towards a "two lanes" approach, with regulation differing according to a drug's patent status. This study analyses the Italian regulatory framework, focusing on policies related to "off-patent" drugs. Three main regulatory innovations have been examined: (i) generics, introduced in Italy for the first time in 1996; (ii) the reference pricing (RP) scheme, under which consumers pay part of the cost of high-priced products; (iii) pharmacists' right of substitution, supported by a regressive margins system. The recent reforms are already producing some worthwhile results, at least in terms of competitive pressure on the (few) substances that run out of patent protection. However, further intervention could be required to achieve long-term sustainability.

Direct medical costs of mycosis fungoides in specialized Italian hospital departments

The objective was to analyze direct medical costs of managing mycosis fungoides (MF). We conducted a retrospective observational study in five Italian specialized departments. The 58 patients enrolled had a confirmed diagnosis of MF stage IIB or worse in 1999. The mean cost per patient was 9,231.40 euro.

A review of the costs of managing childhood epilepsy

Epilepsy is a chronic treatable condition for which new diagnostic tools and several new drugs and non-pharmacological treatments are now available. The cost profile of these options is assessed here through an overview of the available literature focusing on studies of childhood epilepsy. Several methodological problems arise when interpreting the results of economic studies in epilepsy, including the variability of the study population and costs items, the reliability of the sources of cost, the limitations of the methods of data collection and the deficiencies of the study designs, with reference to the measures of treatment benefits. International comparisons are then difficult because economic results cannot be compared on account of differences in monetary issues, clinical practice patterns and healthcare system frameworks. The economic aspects of epilepsy are different in children and adults. Differences are detectable in the incidence and expression of epileptic syndromes, social and emotional impact, availability of antiepileptic drugs, hospital admissions, diagnostic tests and referral to specialists, social assistants and other healthcare professionals. In addition, children have access to medical services only with the help of a caregiver, for whom there may be lost work days or under-employment. The mean annual cost per child with epilepsy was USD 1853 for controlled epilepsy and USD 4950 for uncontrolled epilepsy in a Spanish study performed in 1998 and the annual direct costs per child with epilepsy ranged from euro 844 for patients in remission to euro 3268 for patients with drug-resistant epilepsy in an Italian study done between 1996 and 1998. The Spanish study showed that direct costs are the major source of expenditure for children with epilepsy. These studies along with a number of other cost-of-illness studies in combined populations of adults and children showed that service use and costs increase with more severe forms of illness and seizure frequency, this being more marked in adults than in children. Moderate cost differences may be expected between children (higher) and adults (lower), particularly with reference to initial investigations. Costs of epilepsy are mostly explained by hospital admissions and drugs; in particular, drug costs tend to dominate in more well controlled epilepsy, while both hospital admissions and drugs are significant costs in less well controlled epilepsy. Newly diagnosed patients can incur significant hospital and diagnostic costs. Costs for epilepsy tend to be lower for patients cared for in general practice or outpatient settings than in hospital settings. Seizure control by drugs, ketogenic diet or surgery is associated with a significant reduction in the costs of epilepsy.

Direct medical costs of monitoring and treating patients with Takayasu arteritis in Italy

The study provides the first overall estimate of the costs of Takayasu arteritis (TA) monitoring and treatment in Italy and highlights the differences in cost components across defined subgroups of patients. We estimated resource consumption and direct costs from the Italian National Health Service perspective. We conducted a multicenter, prospective study in 12 medical departments. All the 67 patients recruited met the American College of Rheumatology 1990 criteria for the classification of TA and were followed up for 1 year. For the purpose of analysis they were divided into two groups: "active TA" (patients who had taken at least one drug specific for TA treatment, i.e., corticosteroids and/or cytotoxics), and "inactive TA" (all the remaining patients). The average cost per year was Euro 4,079. Patients with active TA (Euro 5,055) had a significantly higher mean cost per year than those with inactive TA (Euro 1,328). In particular, significant differences were found for costs in general practitioner consultations, laboratory tests, and hospital admissions. These findings suggest that patients not only experience more complications requiring hospital admissions but also see general practitioners more often during the active stage of the disease, presumably in order to obtain a prescription for laboratory tests.

Direct costs of schizophrenia and related disorders in Italian community mental health services: a multicenter, prospective 1-year followup study

The behavior that accompanies schizophrenia and related disorders interferes with professional and social activities. As a result, schizophrenia is one of the most costly psychiatric illnesses. Direct medical costs associated with schizophrenia were estimated from the Italian National Health Service perspective. This was a multicenter observational 1-year study conducted in 14 Italian community mental health centers (CMHCs). Eligible patients were those with a diagnosis of schizophrenia or schizoaffective or schizophreniform disorder who had been followed by the CMHCs for at least 2 years at study entry. Exactly 643 patients were enrolled in the study. The mean direct cost per year was 6,964 (27,025 for schizophrenia and 6,587 for patients with related psychotic disorders) (1998 exchange rate U.S.$1 = 1.121). The present study provides further estimates of the cost of schizophrenia treatment in Italian mental health services and highlights the variability in the single cost components across clinically defined subgroups of patients.

ECONOMIC EVALUATIONS IN ITALY: A REVIEW OF THE LITERATURE

Objectives: To review the economic evaluations (EEs) done in Italy by Italian authors, following a common scheme to allow some comparisons of the studies selected and with the international reviews.

Methods: We selected all the original studies published by Italian authors (in Italian or English) in national and international journals. The period considered was January 1994 to December 2001. Both full and partial economic evaluations were included. Three international databases were interrogated: MEDLINE, Embase, and HealthStar; further articles were added from the internal database of our center (CESAV), which also classifies Italian local publications and journals specialized in health economics.

Results: A total of ninety-nine studies were reviewed. More than half of the fifty-seven full EEs focused on drugs as type of intervention (n=38), followed by diagnostic screening (n=7). The NHS viewpoint was the most used (n=55 studies), followed by that of society (n=27) and hospitals (n=12). Sixty-eight studies only analyzed direct costs and twenty-nine included both direct and indirect costs. Twenty-five of the thirty-eight pharmacoeconomic full EEs were sponsored by companies. In sixteen of the twenty-five sponsored studies, the sponsor's products were the dominant alternative.

Conclusions: The review showed that, in Italy, like elsewhere, there is a gap between theory and practice in EEs, and sponsors can considerably affect the results of EEs.

Direct medical costs of age-related macular degeneration in Italian hospital ophthalmology departments. A multicenter, prospective 1-year study

This study calculated the resource utilization and direct medical costs related to age-related macular degeneration (AMD). We conducted a multicenter observational study in 1999 in seven hospital ophthalmology departments in northern and central Italy. A total of 476 patients aged over 50 years with the diagnoses were classified into three prognostic groups: (a) drusen (23.7%), (b) geographic atrophy (16.4%), and (c) retinal changes associated with choroidal neovascularization (CNV) (59.9%). In addition to the costs reimbursed by the Italian National Health Service, we estimated also patients' out of pocket expenses. The mean cost per patient per year was 383.2 euro; patients with CNV were by far the most costly (540.1 euro, vs. 158.1 euro for drusen and 147.9 euro for geographic atrophy). Hospital costs and diagnostics were the main cost determinants. Services directly paid for by patients (private consultations and OTCs) amounted to 46.5 euro for patients with CNV, 50.3 euro for drusen, and 68.8 euro for geographic atrophy. The major finding of the study was that the presence of CNV involved higher expenditure than drusen or geographic atrophy. This suggests that the costs of AMD rise significantly with the severity of the illness.

Direct medical costs unequivocally related to diabetes in Italian specialized centers

This study estimated the resource utilization and direct medical costs in Italian diabetes centers (DCs). Hospital admissions for major chronic complications were not considered since DCs deliver primary care and follow up only complications unequivocally related to diabetes-acute complications and diabetic foot. The multicenter, prospective, observational study involving 31 Italian DCs included a total of 1,910 patients classified into eight prognostic groups by type of diabetes (types 1 and 2), metabolic control (HbA1c >7.5%, HbA1c < or =7.5%) and age (< or =60, >60). The average total cost of type 1 diabetes per patient per year ranged from 762 euro in group 2 (age < or =60, HbA1c >7.5%) to 1,060 euro in group 4 (age >60, HbA1c >7.5%), and that the cost of type 2 diabetes from 423 euro in group 5 (age < or =60, HbA1c < or =7.5%) to 613 euro in group 8 (age >60, HbA1c >7.5%). The study brought to light the wide variability in the single cost components across clinically defined groups of patients. The cost of diabetes management in the strict sense was significantly affected by the type of diabetes and metabolic control.

Direct Cost of Medical Management of Epilepsy among Adults in Italy: A Prospective Cost-of-Illness Study (EPICOS)

PURPOSE

To investigate the costs of epilepsy from a nationwide survey comparing adult patients included in different prognostic categories.

METHODS

A 12-month prospective observational study was conducted in 15 epilepsy centers from Northern, Central, and Southern Italy. The study population included a random sample of individuals aged 18 years and older with newly diagnosed (ND) epilepsy, seizure remission (R), occasional seizures (OS), active non-drug-resistant (NDR) seizures, drug-resistant (DR) seizures, or surgical candidates (SC). Estimates of the direct costs of care of epilepsy were based on the use of diagnostic examinations, laboratory tests, specialist consultations, hospital admissions, day-hospital days, and drugs, taking the Italian National Health Service perspective.

RESULTS

The sample included 631 patients (ND 62, R 158, OS 155, NDR 114, DR 128, and SC 14). The SC group had the highest total cost per patient (3,619 euros) followed by DR (2,190 euros), ND (976 euros), NDR (894 euros), OS (830 euros), and R (561 euros). For each epilepsy group, the main components of the total cost were drugs and hospital admissions. Drug costs increased from the R group to the DR group. The new antiepileptic drugs (AEDs) were the largest part of the cost of treatment.

CONCLUSIONS

The costs of epilepsy in referral patients vary significantly according to the time course of the disease and the response to treatment. Hospital admissions and drugs are the major sources of expenditure.
