Economic impact of the taxus coronary stent: implications for the Spanish healthcare system

INTRODUCTION AND OBJECTIVES: This article examines the cost impact associated with the utilization of the Taxus drug eluting stent versus a conventional bare-metal stent for percutaneous coronary interventions in a Spanish hospital setting. METHODS: A decision analysis model has been developed to compare the intervention and re-hospitalization costs at 12 and 24 months post-intervention. The analysis considers the general patient population and a high-risk subpopulation (diabetes, small vessel, long lesion). The analysis simulates the results of the TAXUS-IV clinical trial, in a population with similar risks, with appropriate costs, and including budget impact analyses with alternative utilization scenarios. RESULTS: The expected average per patient hospital cost at 12 months was 6934 euros with Taxus and 6756 euros with bare-metal stent (and increase of 2.6%). At 24 months, per patient hospital cost was 6,991 euros for Taxus and 6887 euros for bare-metal stent (an increase of 1.5%). In the high-risk subpopulation, Taxus was overall cost saving as compared to bare-metal stent both at 12 months (decrease of 3.0%) and 24 months (decrease of 4.7%). CONCLUSIONS: Use of Taxus in the overall population slightly raises treatment costs, while in patients with greater risk of restenosis the treatment cost is reduced. Given the decrease in the number of repeat revascularizations with this stent, the cost-effectiveness relationship could be acceptable in the general patient population and is dominant in the high-risk subpopulation.     

Successful treatment with topical mesalazine for a patient with intractable crohn’s colitis

A 32‐year‐old woman was admitted to our hospital for intractable Crohn’s disease. Crohn’s colitis was diagnosed at another hospital in August 1999. She had been successfully treated with oral mesalazine and an elemental diet. In March 2000, she had been admitted to the previous hospital for her third flare up of symptoms. She responded to oral mesalazine administration and total parenteral nutrition, but bowel symptoms were exacerbated and C‐reactive protein level was elevated after a polymeric diet was started. Prednisolone 30 mg/day was started in addition to total parenteral nutrition, but hematochezia and elevated serum C‐reactive protein level persisted, and she was referred to our hospital. She had about four bowel movements per day with fresh bleeding at the time of admission. Total parenteral nutrition and oral mesalazine were continued. The dose of oral prednisolone was increased from 15 mg/day to 40 mg/day. However, the frequency of bowel movements did not decrease and C‐reactive protein level continued to exceed 1.5 mg/day. Mesalazine enemas were begun on 23 January 2001, and were effective in improving hematochezia and serum C‐reactive protein. Both radiologic and endoscopic examinations revealed remarkable improvement.     

Cost analysis from two randomized trials of sirolimus-eluting stents versus paclitaxel-eluting stents in high-risk patients with coronary artery disease.

OBJECTIVES: This study sought to analyze the cost of percutaneous coronary interventions with use of sirolimus-eluting stents (SES) or paclitaxel-eluting stents (PES) in patients at high risk of restenosis. BACKGROUND: Recent studies have shown different clinical efficacy with these drug-eluting stents. Whether this difference extends on cost estimates between the 2 stents is not known. METHODS: We included 450 patients with diabetes mellitus and in-stent restenosis from 2 randomized studies comparing SES with PES. Assigned costs for the economic evaluation were the initial hospitalization and all subsequent cardiac-related inpatient/outpatient health resources during 9 to 12 months of clinical follow-up. The economic evaluation was performed from the health insurance system's perspective. RESULTS: There were no differences between the 2 study groups regarding mortality (p = 0.78) and myocardial infarction rates (p = 0.76). Target lesion revascularization was performed in 16 patients (7.1%) in the SES group and in 34 patients (15.1%) in the PES group (p = 0.01). Initial hospital costs were not significantly different between the 2 stents (p = 0.53). The follow-up costs were, however, different: 2,684 +/- 2,072 euros per patient treated with SES and 4,527 +/- 6,466 euros per patient treated with PES (p < 0.001). Total costs also differed at the end of the follow-up: 8,924 +/- 3,077 euros per patient treated with SES and 10,903 +/- 7,205 euros per patient treated with PES (p < 0.001). CONCLUSIONS: In patients at high risk of restenosis, use of SES is associated with lower costs compared with PES. The cost savings are mainly due to the reduced need of repeat revascularization procedures with SES.     

Direct and indirect costs attributable to osteoarthritis in active subjects

OBJECTIVE: To estimate the direct and indirect costs of osteoarthritis (OA) in an active population, and to identify factors significantly influencing these expenditures. METHODS: A cohort of 3,440 subjects employed by the Liège City Council was followed prospectively for 6 months. Subjects were asked to report monthly OA related health resource utilization (contacts with health professionals, medical examinations, drug consumption, etc.) and absence from work. Health related quality of life (HRQOL) was evaluated at baseline using the Medical Outcomes Study Short-form 36 (SF-36). Logistic regression analysis identified factors associated with the probability that the individual incurred costs, and multiple regression identified factors influencing the magnitude of these costs. RESULTS: A total of 1,811 subjects filled in at least one questionnaire (response rate 52%). The mean duration of followup was 3.46 months. Self-reported prevalence of OA was 34.1%. The mean total direct costs were 44.5 euros per OA patient-month. Contacts with health professionals, medical examinations, drugs, and hospital stays accounted for 23.7 euros, 8.7 euros, 6.7 euros, and 4.9 euros, respectively, per OA patient-month. The average number of sick-leave days was 0.8 per OA patient-month. From a payer's perspective, this loss of productivity represented a mean cost of 64.5 euros per OA patient-month. We also recorded 0.02 mean days off work per active subject-month due to informal care by relatives, yielding a mean cost of 1.8 euro per active subject-month for the employer. Poorer scores for most of the dimensions of the SF-36 at baseline were significantly associated with greater likelihood of incurring direct and indirect costs and with higher costs among subjects who reported costs. If we consider the overall cohort of active subjects, the burden of OA related to the direct and indirect costs was 15.2 euros and 23.8 euros, respectively, per active subject-month. CONCLUSION: Direct and indirect costs attributable to OA are substantial, with productivity related costs being predominant. Poorer HRQOL was a major determinant of these expenditures.     

Home Parenteral Nutrition: a direct costs study in the approved centres of Montpellier and Strasbourg

AIM: Home Parenteral Nutrition (HPN) is an expensive but relatively cost effective therapy. In France, HPN has been organized around regionally located approved major centers. Few French studies have focused on the economic costs of HPN. The objective of this study was to assess the direct costs of HPN in two approved centers. PATIENTS AND METHODS: Included patients and their nurses filled in a questionnaire in a prospective analysis. The questionnaires were complemented by data from the dispensary, the head of the institution's financial administration and different organizations. Cost were calculated according to the national health insurance fund and hospitalisation prices for 2003. RESULTS: The direct cost was on average 83 euro per patient per day: 58% for drugs and material, 16% for hospital personnel, 16% for non-institutional caregivers, 4% for patient transportation, 4% for material transportation, and 2% for laboratory tests. The costs reimbursed by the national health insurance fund for laboratory tests, non-institutional caregivers and patient transportation were on average 18 euro per patient per day. Hospital funds provided 78% of the total costs. Daily costs were lower in Strasbourg as compared with Montpellier (62.1 vs 103.3 euro). CONCLUSION: The cost of the products administered accounts for the majority of daily costs of home parenteral nutrition which is essentially funded by hospital resources. The lower daily costs per patient in Strasbourg may be related to greater patient independence.     

Financial costs of alcoholism treatment programs: a longitudinal and comparative evaluation among four specialized centers

BACKGROUND: Alcoholism is a worldwide problem. Many strategies for alcohol detoxification and relapse prevention exist, but each alcohol treatment center has its own program. The objective of this study was to analyze and compare the financial cost and effectiveness of alcohol treatment programs from inpatient stay to follow-up 1 year later. This was a prospective, open, nonrandomized study of 4 specialized alcohol treatment centers and 267 patients admitted for alcohol detoxification. METHODS: We recorded all medical and nonmedical interventions related to the program during patient stay in the hospital and every 3 months after discharge for 1 year and recorded the occurrence of alcohol relapse. Financial evaluation was based on the prices of refund from the French national health insurance service. RESULTS: The mean cost of hospitalization ranged from 1326 euros to 1917 euros(p = 0.001), a variation mainly due to the difference in the length of hospital stay but also to the cost of the inpatient program, routine medical checkups, and drugs administered. The mean cost of 1 year of follow-up per patient ranged from 419 euros to 1704 euros (p = 0.001). The efficiency, corresponding to the money spent to prevent the relapse of one patient during 1 month, was approximately 500 euros/month in three centers and 658 euros in the fourth. However, for a similar efficiency, the effectiveness, assessed by the mean time without relapse, was significantly (p = 0.001) different; center 1, which had the highest total cost, had an effectiveness 1.56 times higher than center 3, which had the lowest cost. CONCLUSIONS: This work emphasizes the heterogeneity of the costs and effectiveness of alcoholism treatment programs and suggests that research should be conducted to determine which program is the most rational, cost-efficient, and beneficial for patients and the public health office economy.     

An economic evaluation of Losartan therapy in type 2 diabetic patients with nephropathy: an analysis of the RENAAL study adapted to France

BACKGROUND: The RENAAL study enrolled 1,513 patients with type 2 diabetes mellitus and nephropathy defined by the presence of proteinuria (urinary albumin: creatinine ratio 300 mg/g or proteinuria > 500 mg per day). Compared to placebo, losartan therapy reduced by 16% (p=0.02) the risk of a composite endpoint (doubling of baseline serum creatinine level, end stage renal disease, or death) and by 28% (p=0.002) the risk of progression to end stage renal disease (ESRD). METHODS: The objective of this study was to compare, using French economic data, the additional cost of losartan therapy with the savings in cost generated by a decrease in the number of end stage renal disease days. Prospectively collected health care resource utilization were used (N(losartan)=751, N(placebo)=762). The follow-up period was 4 years. RESULTS: The mean cumulative cost of losartan over 4 years was 1,603 euros per patient. The reduction in the number of ESRD days over 4 years in patients treated with losartan significantly decreased costs associated with ESRD by 7,438 euros per patient (CI 95%: 3,029 euros - 11,847 euros, p=0.001). Compared to the placebo group, the average cost per patient over 4 years in the losartan group was lower by 5,834 euros (CI 95%: 1,407 euros - 10,301 euros, p=0.01). CONCLUSION: In addition to the medical benefit, this analysis demonstrated the economic relevance of treatment with losartan in type 2 diabetic patients with nephropathy.     

Costs of chronic dialysis in a public hospital: myths and realities

In this study regular dialysis treatment costs during 1998 and 1999 in a public hospital, which is responsible for a population of 178,000, has been analysed. Hemodialysis (HD) and peritoneal dialysis (PD) costs have been differentiated and compared with those of external providers. The best technical and productive efficiency of both treatments have been estimated by analyzing the "treatment cost/human resources of the community utilized" relationship. The HD treatment costs per patient per year were 20,343 and 18,871 euros in 1988 and 1,999, respectively, lower than the costs reported in other studies. In 1999 these costs were similar to those of external providers and lower than the PD treatment costs (23,295 euros). HD retains its advantage even after costs of erythropoietin, hospital admissions and transport are included. In the hospital studied, the best technical efficiency in HD would be reached with 64 patients on treatment (17,851 euros per patient per year) and in PD with 48 patients (21,167 euros per patient per year). If we take into account our population characteristics and consider a patient distribution of 70% on HD and 30% on PD, the best productive efficiency would be reached with 56 patients on HD (17,916 euros per patient per year) and 24 patients on PD (21,813 euros per patient per year). HD confers the greatest economic and social benefits on the population supplied by the hospital since it provides the community with more jobs than PD in relation to treatment costs while the two yield the same clinical results. In conclusion, HD in a public hospital, at least in our environment, may be efficient and competitive with HD from external providers and it may be more efficient and provide a bigger economic and social profit for the population serviced by the hospital than PD, at least while the current supply systems for this treatment in our country are maintained.     

Essential fatty acid deficiency in human adults during total parenteral nutrition.

Three patients undergoing prolonged total parenteral nutrition at home developed skin lesions, characterized by dryness and scaly appearance, initially confined to the folds but becoming subsequently generalized. Fatty acid measurements in plasma of these patients showed a markedly abnormal lipid pattern: accumulation of 5,8,11-eicosatrienoic acid (20:3omega9) and a high 20:3omega9-to-20:4omega6 ratio. When parenteral fat (Intralipid) was administered, 500 ml/day, serial measurements of fatty acids showed a progressive normalization of the abnormal pattern and a dramatic improvement in the skin lesions. It appears that the daily requirement for linoleic acid in the adult, particularly during the period of rapid anabolism, has not been clearly established. Because more and more patients are becoming partly or totally dependent on parenteral nutrition for prolonged periods of time, the availability of parenteral fat preparations is urgently needed.     

Cost-effectiveness of a multidisciplinary intervention model for community-dwelling frail older people

BACKGROUND: There is growing interest in geriatric care for community-dwelling older people. There are, however, relatively few reports on the economics of this type of care. This article reports about the cost-effectiveness of the Dutch Geriatric Intervention Program (DGIP) compared to usual care in frail older people at 6-month follow-up from a health care system's point of view. METHODS: We conducted this economic evaluation in an observer-blind randomized controlled trial (Dutch EASYcare Study: ClinicalTrials.gov Identifier NCT00105378). Difference in treatment effect was calculated as the difference in proportions of successfully treated patients (prevented functional decline accompanied by improved well-being). Incremental treatment costs were calculated as the difference in mean total care costs. The incremental cost-effectiveness ratio (ICER) was expressed as total cost per successful treatment. Bootstrap methods were used to determine confidence intervals (CI) for these measures. RESULTS: The average cost of the intervention under study (DGIP) was 998 euros (95% CI, 888-1108). The increment in total cost resulting from DGIP was a little over 761 euros (-3336 to 4687). Hospitalization and institutionalization costs were less; home care, adult day care, and meals-on-wheels costs were higher. There was a significant difference in proportions of successful treatments of 22.3% (4.3-41.4). The number needed to treat was approximately 4.7 (2.3-18.0). The ICER is 3418 euros per successful treatment (-21,458 to 45,362). The new treatment is cost-effective at a willingness-to-pay of 34,000 euros. CONCLUSION: The results of this economic evaluation suggest that DGIP is an effective addition to primary care for frail older people at a reasonable cost.     

Reduction in hospitalization rates following cardiac resynchronisation therapy in cardiac failure: experience from a single centre.

AIMS: Frequent, lengthy hospital admissions for congestive cardiac failure (CCF) result in excessive health care costs. Cardiac resynchronisation therapy (CRT) is a novel treatment option for patients with CCF and associated cardiac conduction defects. We investigated whether CRT resulted in significant improvements in New York Heart Association (NYHA) symptom class, exercise tolerance, and hospitalization rates in such patients. METHODS: Twenty-seven patients who underwent CRT in a single centre were studied, with NYHA symptom class, exercise tolerance and hospitalization rates noted in the 12 months prior to and following CRT. RESULTS: Following 12 months of CRT, NYHA symptom class improved from 3.3 +/- 0.5 to 2.1 +/- 0.4 (P < 0.05). Exercise tolerance, assessed by 6 min hall walk test increased by 64% from 195 +/- 114 m to 320 +/- 85 m (P = 0.007). Days in hospital for stabilisation of cardiac failure decreased by 98% from 472 to 9 days (P < 0.001). Significant hospitalization cost savings of 201,684 euros were calculated, with an overall saving of 12,420 euros. CONCLUSIONS: These data demonstrate that CRT results in significant improvement in clinical parameters, and considerable reductions in hospital admissions, and costs in patients with CCF.     

Clinical and metabolic efficacy of glutamine-supplemented parenteral nutrition after bone marrow transplantation. A randomized, double-blind, controlled study.

OBJECTIVE: To determine whether glutamine-supplemented parenteral nutrition improves nitrogen retention and reduces hospital morbidity compared with standard parenteral nutrition after bone marrow transplantation. DESIGN: Double-blind, randomized, controlled clinical trial. SETTING: University teaching hospital. PATIENTS: Forty-five adults receiving allogeneic bone marrow transplants for hematologic malignancies. INTERVENTION: Parenteral nutrition was initiated the day after bone marrow transplantation (day 1). The experimental solution was supplemented with L-glutamine (0.57 g/kg body weight per day) and provided estimated requirements for energy and protein. The control solution was a standard, glutamine-free, isonitrogenous, isocaloric formula. MEASUREMENTS: Nitrogen balance was determined between days 4 and 11 in the initial 23 patients. The incidence of clinical infection and microbial colonization, time until bone marrow engraftment, indices of clinical care, and other data related to hospital morbidity were recorded for all patients. RESULTS: The glutamine-supplemented patients (n = 24) were clinically similar to the controls (n = 21) at entry. Nutrient intake was similar in both groups; however, nitrogen balance was improved in the glutamine-supplemented patients relative to the controls (-1.4 +/- 0.5 g/d compared with -4.2 +/- 1.2; P = 0.002). Fewer experimental patients developed clinical infection (three compared with nine in the control group; P = 0.041), and the incidence of microbial colonization was also significantly reduced. Hospital stay was shortened in patients receiving glutamine supplementation (29 +/- 1 d compared with 36 +/- 2 d; P = 0.017). CONCLUSION: Patients receiving glutamine-supplemented parenteral nutrition after bone marrow transplantation had improved nitrogen balance, a diminished incidence of clinical infection, lower rates of microbial colonization, and shortened hospital stay compared with patients receiving standard parenteral nutrition. These effects occurred despite no differences between groups in the incidence of fever, antibiotic requirements, or time to neutrophil engraftment.     

Mortality and economics in short bowel syndrome

The incidence of patients with short-bowel syndrome (SBS) has increased over the years due to progress of intensive care medicine and parenteral nutrition techniques. These techniques have significantly improved the prognosis of neonates, children and adults who have lost major parts of their intestinal tract. Long-term survival is possible and does not depend primarily on the length of the remaining bowel but on complications such as parenteral nutrition-associated cholestasis, recurrent septicaemia, central venous catheter infections, and the motility of the remaining intestine. Thus, the overall related mortality in infants with SBS ranges from 15 to 25%, and in adults from 15 to 47%, depending on the age of the patients, the underlying disease, and the duration on total parenteral nutrition. Home parenteral nutrition (HPN) significantly decreases the complication rate and improves the psychological situation of the patient. Additionally, HPN reduces in-hospital cost significantly. Nevertheless, the annual costs/patient are between $100000 and $150000. The mortality rate of SBS patients on HPN is about 30% after 5 years, which is still lower than the 5-year survival rate of intestinal grafts, and it is about equal to patients' survival after intestinal transplantation. However, the overall costs of a successful intestinal transplantation are already lower after 2 years when compared with the cost of a prolonged HPN programme.     

The societal burden of HIV/AIDS in Northern Italy: an analysis of costs and quality of life

This study aims to measure the direct and indirect costs of HIV/AIDS care and quality of life (QoL) of HIV-infected patients in Northern Italy. We conducted a prospective cohort study over 12 months, enrolling a sample of 121 patients with HIV infection from two cities in Northern Italy. Patients were surveyed at baseline and were followed-up at 6 and 12 months. To assess the relationship between costs and stage of disease, patients were categorized into three groups at baseline: "No HAART" (asymptomatic and never before on highly active antiretroviral therapy (HAART)), "Stable HAART" (HAART with mild HIV infection and no prior opportunistic infections) and "HAART failure" (primary HAART regimen was altered because of severe side effects or immunological failure). Direct medical costs were based on utilization of (day) hospital admissions, diagnostic procedures, laboratory tests, clinic visits, consultations and antiretroviral drug use. Indirect costs included production losses due to absence from work, reduced productivity at work and reduced unpaid labour participation. QoL was assessed by visual analogue scale. Parametric regression was used to estimate the expected value and the standard deviation of annual costs per patient. The expected value of total annual costs was 1818 euros and 9820 euros and 12,332 euros, for groups "No HAART", "Stable HAART" and "HAART failure" respectively. We estimated annual expected earnings as 14,994 euros and 10,811 euros and 9820 euros for the same respective groups. The expected value of QoL on a scale of 0-1 in these same patient groups was 0.80, 0.78 and 0.64. We conclude that indirect costs contribute substantially to total costs and are comparable in magnitude to the direct costs excluding antiretroviral drugs. The costs of inpatient care in our cohort were almost negligible compared to total costs. Despite being in treatment, many patients were still gainfully employed and generated substantial expected annual earnings.     

Cost of illness in rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and systemic lupus erythematosus in Germany

OBJECTIVE: To estimate and compare the direct and indirect costs of illness in rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis (PsA) and systemic lupus erythematosus (SLE), and to evaluate the effect of sex, disease duration and functional status on the various cost domains. METHODS: Data of outpatients, aged 18-65, with rheumatoid arthritis (n = 4351), ankylosing spondylitis (n = 827), PsA (n = 908) or SLE (n = 844), who were enrolled in the national database of the German collaborative arthritis centres in 2002, were analysed. Data on healthcare consumption, out-of-pocket expenses and productivity losses were derived from doctors and patients. For the calculation of indirect costs, the human capital approach (HCA) and the friction cost approach (FCA) were applied. RESULTS: Mean direct costs amounted to 4737 euros a year in rheumatoid arthritis, 3676 euros in ankylosing spondylitis, 3156 euros in PsA and 3191 euros in SLE. By using the HCA, total costs were calculated at 15,637 euros in rheumatoid arthritis, 13,513 euros in ankylosing spondylitis, 11,075 euros in PsA and 14,411 euros in SLE, whereas with the FCA the numbers were 7899 euros, 7204 euros, 5570 euros and 6518 euros, respectively. Costs increased with disease duration and were strongly dependent on functional status. In patients with the highest disability (<50% of full function), the total costs on applying the HCA were 34,915 euros in rheumatoid arthritis, 29,647 euros in alkylosing spondylitis, 37,440 euros in PsA and 32,296 euros in SLE. CONCLUSION: The costs of illness are high in all four diseases, with a strong effect of functional status on total costs. Indirect costs differ by the factor 3, based on whether the HCA or the FCA is used.     

ABC (Atrial fibrillation Better Care) Pathway and Healthcare Costs in Atrial Fibrillation: The ATHERO-AF Study

BACKGROUNDThe Atrial fibrillation Better Care (ABC) pathway has been proposed to streamline patient management in an integrated, holistic manner. Compliance to ABC resulted in lower incidence of cardiovascular events, but its impact on health-related costs has not been evaluated.METHODSExploratory analysis of costs related to cardiovascular events in the ATHERO-AF prospective cohort study including atrial fibrillation patients on vitamin K antagonists. A Diagnosis-Related Group code provided by the Italian Ministry of Health was assigned to each event to estimate the relative cost. The analysis was performed by dividing patients according to ABC pathway components.RESULTSOverall, 118 cardiovascular events incurred a cost of 1,017,354 euros (1,149,610 USD). The mean total costs were 13,050 (14,747 USD) and 11,218 euros (12,676 USD) for a non-fatal cardiac event or ischaemic stroke, respectively. The cost-saving was 719 euros (813 USD) per patient-year for patients in group A vs non-A, 703 euros (794 USD) for B vs non-B, 480 euros (542 USD) for C vs non-C and 2776 euros (3,137 USD) for ABC vs non-ABC. The cost per event increased with the number of uncontrolled ABC components: 507 euros (573 USD) for 1, 965 euros (1,091 USD) for 2 and 3,431 euros (3,877 USD) for patients not having any of the three components of the ABC.CONCLUSIONSManagement of atrial fibrillation patients according to the ABC pathway was associated with significantly lower health-related costs. Application of the ABC pathway may help reduce healthcare costs related to cardiovascular events in this high-risk patient population.     

Estimated annual costs of prophylaxis and treatment of venous thromboembolic events associated with major orthopedic surgery in France.

Venous Thromboembolism (VTE) remains a major complication following orthopedic surgery despite heparin prophylaxis. Clinical consequences associated with this complication are deep vein thrombosis (DVT), pulmonary embolism, and long-term consequences of DVT, especially Postthrombotic syndrome (PTS). The purpose of the present study was to estimate the annual direct costs of VTE following major orthopedic surgery of the lower limb in France. This cost of illness study was performed by using available information from health system databases (1999) and literature and specific surveys (2002). Direct costs were calculated by using estimates of the number of patients with major orthopedic surgery in France during one year. Patients presenting with VTE were identified from the national disease-related group inpatient database. Additional resource consumption was identified by comparison with disease-related groups without the VTE complications. Ambulatory care costs after hospitalization, for recurrences and PTS, were estimated from specific surveys of general practitioners and venous disease specialists. Total annual costs of VTE associated with major orthopedic surgery for the French Sickness Fund were estimated to be approximately 60 million euros over 1 year with 28 million euros for inpatient care and 30 million euros for recurrences and PTS.     

Antibiotic use and cost indicators at a rural hospital: a pilot project

BACKGROUND: Recently, simple antibiotic use and cost indicators were developed for use in long-term care facilities. It was hypothesized that these indicators also may be applicable to the acute hospital setting. METHODS: For a 24-month period, data were collected quarterly on antibiotic use and cost indicators for 11 primary care physicians in a 40-bed rural hospital. Indicators included antimicrobial use ratio (AUR, ratio of the number of antibiotic days to the number of patient care days), cost per antibiotic day, and cost of antibiotics per patient care day. One-way analysis of variance and simple linear regression were used to analyze data. RESULTS: Quinolones (oral plus parenteral) accounted for 26% of the total antibiotic days (N = 6020) followed by ceftriaxone (19%) and cefuroxime (11.8%; oral plus parenteral). Overall trends in antibiotic use and cost included a significant increase in quarterly AUR (R(2) = 0.78, P =.004) and cost per patient care day (R(2) = 0. 82, P =.002) but no significant change in quarterly total antibiotic costs or cost per antibiotic day. Among physicians there was a significant difference in mean quarterly AUR (P <.001) and mean quarterly cost per patient care day (P <.001) but no significant difference in mean quarterly cost per antibiotic day. Variation in physician-specific cost per patient care day was best explained by variation in AUR (R(2) = 0.75, P <.001). CONCLUSIONS: Significant variation in simple antibiotic use and cost indicators was identified at a rural hospital from both the facility and physician perspective. Standardized methods for antibiotic use and cost monitoring, like the one described in this article, are required before the relationship between antibiotic use and resistance can be fully understood.     

Effect of early enteral combined with parenteral nutrition in patients undergoing pancreaticoduodenectomy

AIM:To investigate the effect of early enteral nutrition(EEN)combined with parenteral nutritional support in patients undergoing pancreaticoduodenectomy(PD).METHODS:From January 2006,all patients were given EEN combined with parenteral nutrition(PN)(EEN/PN group,n=107),while patients prior to this date were given total parenteral nutrition(TPN)(TPN group,n=67).Venous blood samples were obtained for a nutrition-associated assessment and liver function tests on the day before surgery and 6 d after surgery.The assessment of clinical outcome was based on postoperative complications.Follow-up for infectious and noninfectious complications was carried out for 30 d after hospital discharge.Readmission within 30 d afterdischarge was also recorded.RESULTS:Compared with the TPN group,a significant decrease in prealbumin(PAB)(P=0.023)was seen in the EEN/PN group.Total bilirubin(TB),direct bilirubin(DB)and lactate dehydrogenase(LDH)were significantly decreased on day 6 in the EEN/PN group(P=0.006,0.004 and 0.032,respectively).The rate of gradeⅠcomplications,gradeⅡcomplications and the length of postoperative hospital stay in the EEN/PN group were significantly decreased(P=0.036,0.028and 0.021,respectively),and no hospital mortality was observed in our study.Compared with the TPN group(58.2%),the rate of infectious complications in the EEN/PN group(39.3%)was significantly decreased(P=0.042).Eleven cases of delayed gastric emptying were noted in the TPN group,and 6 cases in the EEN/PN group.The rate of delayed gastric emptying and hyperglycemia was significantly reduced in the EEN/PN group(P=0.031 and P=0.040,respectively).CONCLUSION:Early enteral combined with PN can greatly improve liver function,reduce infectious complications and delayed gastric emptying,and shorten postoperative hospital stay in patients undergoing PD.     

Cost effectiveness of etanercept (Enbrel) in combination with methotrexate in the treatment of active rheumatoid arthritis based on the TEMPO trial

OBJECTIVE: To estimate the cost effectiveness of combination treatment with etanercept plus methotrexate in comparison with monotherapies in patients with active rheumatoid arthritis (RA) using a new model that incorporates both functional status and disease activity. METHODS: Effectiveness data were based on a 2 year trial in 682 patients with active RA (TEMPO). Data on resource consumption and utility related to function and disease activity were obtained from a survey of 616 patients in Sweden. A Markov model was constructed with five states according to functional status (Health Assessment Questionnaire (HAQ)) subdivided into high and low disease activity. The cost for each quality adjusted life year (QALY) gained was estimated by Monte Carlo simulation. RESULTS: Disease activity had a highly significant effect on utilities, independently of HAQ. For resource consumption, only HAQ was a significant predictor, with the exception of sick leave. Compared with methotrexate alone, etanercept plus methotrexate over 2 years increased total costs by 14,221 euros and led to a QALY gain of 0.38. When treatment was continued for 10 years, incremental costs were 42,148 euros for a QALY gain of 0.91. The cost per QALY gained was 37,331 euros and 46,494 euros, respectively. The probability that the cost effectiveness ratio is below a threshold of 50,000 euros/QALY is 88%. CONCLUSION: Incorporating the influence of disease activity into this new model allows better assessment of the effects of anti-tumour necrosis factor treatment on patients' general wellbeing. In this analysis, the cost per QALY gained with combination treatment with etanercept plus methotrexate compared with methotrexate alone falls within the acceptable range.
