OBJECTIVE
Palivizumab is a prophylactic therapy shown to reduce the number of respiratory syncytial virus (RSV)-related hospitalizations but has a high acquisition cost. The objective was to systematically examine the cost effectiveness of palivizumab in defined infant groups and identify important cost and outcome determinants.
METHODS
Literature searches of MedLine, the Cost-Effectiveness Analysis registry and the UK NHS Economic Evaluation Database (NHS EED) were conducted to identify economic evaluations of palivizumab compared to no prophylactic treatment for RSV prevention in any infant population. Study quality was evaluated using Quality of Health Economic Studies (QHES) criteria and results converted to 2009 CAN$ for comparison.
RESULTS
A total of 23 articles meeting inclusion criteria were identified, including 11 cost-utility analyses (CUAs) and 12 cost-effectiveness analyses (CEAs). Quality of individual analyses was fairly high (range 60-100, median 86). Results ranged from cost dominance for prophylaxis to $3,365,769/QALY depending on population, outcome measures, and input parameters. Base-case and sensitivity-analysis mortality rates varied between studies and influenced results.
CONCLUSIONS
RSV prophylaxis with palivizumab is cost effective in specific groups of high-risk infants, especially those with multiple environmental risk factors. Cost-effectiveness estimates vary between populations and settings and are more positive in those at highest risk for RSV hospitalization.
LIMITATIONS
Direct comparison of the published reports was limited by restriction to English language articles and the varied methodologies, input measures, and populations across the studies reviewed. Although reported currencies were converted to a common unit for comparison, this does not completely account for monetary and inflation differences.

Review
BACKGROUND
Respiratory syncytial virus (RSV) infection causes acute lung infection in infants and young children worldwide, resulting in considerable morbidity and mortality. Children with cystic fibrosis (CF) are prone to recurrent lung inflammation, bacterial colonisation and subsequent chronic airway disease, putting them at risk for severe RSV infections requiring intensive care and respiratory support. No treatment currently exists, hence prevention is important. Palivizumab is effective in reducing RSV hospitalisation rates and is recommended for prophylaxis in high-risk children with other conditions. It is unclear if palivizumab can prevent RSV hospitalisations and intensive care unit admissions in children with CF.
OBJECTIVES
To determine the efficacy and safety of palivizumab (Synagis((R))) compared with placebo, no prophylaxis or other prophylaxis, in preventing hospitalisation and mortality from RSV infection in children with CF.
SEARCH STRATEGY
We searched the Cochrane CF and Genetic Disorders Group Trials Register and scanned references of the eligible study and related reviews.Last search: 20 January 2010.
SELECTION CRITERIA
Randomised and quasi-randomised studies.
DATA COLLECTION AND ANALYSIS
The authors independently extracted data and assessed risk of bias.
MAIN RESULTS
One study (186 infants up to two years old) comparing five monthly doses of palivizumab (N=92) to placebo (N=94) over one RSV season was identified and met our inclusion criteria. At six months follow-up, one participant in each group was hospitalised due to RSV; there were no deaths in either group. In the palivizumab and placebo groups, 86 and 90 children experienced any adverse event, while 5 and 4 children had related adverse events respectively. Nineteeen children receiving palivizumab and 16 receiving placebo suffered serious adverse events; one participant receiving palivizumab discontinued due to this. At 12 months follow-up, there were no significant differences between groups in number of Pseudomonas bacterial colonisations or change in weight-to-height ratio.
AUTHORS' CONCLUSIONS
We identified one randomised controlled trial comparing five monthly doses of palivizumab to placebo in infants up to two years old with CF. While the overall incidence of adverse events was similar in both groups, it is not possible to draw conclusions on the safety and tolerability of RSV prophylaxis with palivizumab in infants with CF because the trial did not specify how adverse events were classified. Six months after treatment, the authors reported no clinically meaningful differences in outcomes; however no data were provided. Additional randomised studies are needed to establish the safety and efficacy of palivizumab in children with CF.

Review
Respiratory syncytial virus (RSV) is the leading cause of infant hospitalization in the US. The economic burden of severe disease is substantial, including hospitalization costs and out-of-pocket expenses. RSV prophylaxis with either RSV immune globulin intravenous (RSV-IGIV) or palivizumab has been shown to be effective in reducing RSV-related hospitalizations. Motavizumab, a new enhanced-potency humanized RSV monoclonal antibody, is presently in clinical trials. RSV-IGIV and palivizumab are associated with high acquisition costs. Cost-effectiveness analyses are therefore of great importance in helping to determine who should receive RSV prophylaxis. Six studies have analysed the cost effectiveness of RSV-IGIV, 14 have analysed the cost effectiveness of palivizumab and five have analysed the cost effectiveness of both agents, two of which directly compared palivizumab with RSV-IGIV. The cost effectiveness of motavizumab has not been studied. Significant variation exists in the modelling used in these analyses. Many studies have examined short-term benefits such as reducing hospitalizations and associated costs, while fewer studies have examined long-term benefits such as QALYs or life-years gained. The payer and society have been the most common perspectives used. The endpoints examined varied and generally did not account for the potential impact of RSV prophylaxis on RSV-related complications such as asthma. While some studies have reported acceptable cost-effectiveness ratios for RSV prophylaxis, the majority failed to show cost savings or cost-effectiveness ratios below commonly accepted thresholds for either RSV-IGIV or palivizumab. Cost effectiveness of RSV prophylaxis tended to be more favourable in populations with specific risk factors, including premature infants < or =32 weeks' gestational age, and infants or children aged < 2 years with chronic lung disease or congenital heart disease. Comparing the results of economic analyses of the two agents suggests palivizumab may be the more cost-effective option in the population for which RSV prophylaxis is recommended. Over time, the acquisition cost of RSV prophylaxis agents, a major cost driver, may decrease, and more acceptable outcomes of economic analyses may result. Albeit important, the results of economic analyses are not the only tool that decision makers rely on, as population-specific risk factors, and efficacy and safety data must be considered when developing treatment guidelines and making clinical decisions.

Review
BACKGROUND
Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infection (LRTI) in infants and young children, accounting for approximately 75,000-125,000 hospitalizations per year. It is estimated that in 2000, RSV infection accounted for 1.7 million office visits, 402,000 emergency room visits, and 236,000 hospital outpatient visits per year for children younger than 5 years of age. Palivizumab, a humanized monoclonal antibody directed against RSV, is the only immunoprophylaxis therapy approved by the FDA for prevention of serious lower respiratory tract disease caused by RSV in infants (up to 2 years of age) who meet 1 or more of the following criteria for high risk: (a) gestational age up to 35 weeks;(b) diagnosis of chronic lung disease (CLD, formerly bronchopulmonary dysplasia [BPD]); or (c) diagnosis of cyanotic or complex congenital heart disease. The RSV season typically occurs between November and March but may vary by region. During the period of our review, depending on local duration of the RSV season, infants usually required 5 monthly (every 28-30 days) intramuscular injections of palivizumab. Infants born in the middle of the season received their palivizumab doses from the time of birth to the end of the season and, therefore, may have required less than 5 doses.It is unclear if compliance with monthly doses is a problem and whether noncompliance increases the risk of RSV hospitalizations in routine clinical practice.
OBJECTIVES
To (a) identify and describe compliance rates and the factors that influence parental compliance with immunoprophylaxis regimens, (b)review intervention programs and describe those that have been associated with increased compliance, and (c) summarize the association of compliance with RSV hospitalization rates.
METHODS
An electronic literature search was conducted using journal databases, including Ovid, Current Contents, Embase, Medline In-Process & Other Non-Indexed Citations; Ovid Medline, PubMed, and Web of Science;and an abstract database, Medical Intelligence Solution, for citations through April 2008. Specific search terms used were palivizumab with patient compliance, patient adherence, or patient persistence.
RESULTS
Twenty-five articles and abstracts met the inclusion criteria. Available studies were mostly retrospective or observational prospective.Compliance, defined in various ways across the studies, varied between 25% and 100%, and 12 studies identified some of the factors related to noncompliance. Compliance generally was lower among Medicaid patients,African American patients, and other minorities. Ten studies (3 manuscripts and 7 abstracts) investigated the association of administration of prophylaxis through monthly home visits by a health professional with parental compliance with therapy. Most of the home-based programs were associated with higher compliance rates compared with clinic or office programs.Rates as high as 94% and 64% were achieved when Medicaid infants and infants of minority descent, respectively, received their doses through a home health program. When these infants received their doses at a clinic or office, depending on the definition of compliance, rates were 61%-100% for Medicaid infants and 44% for infants of minority descent. Reminder telephone calls to parents or caregivers, comprehensive multidisciplinary programs that included extensive counseling of parents, calendars with sticker reminders, and education in the language native to parents also were associated with increased compliance, although statistical significance was reported in only 1 study. Several studies recommended educating parents on the benefits of RSV prophylaxis, alleviating transportation and language difficulties, recognizing cultural differences and biases, and clarifying misperception of RSV illness severity. Home health programs had lower rates of RSV hospitalizations than office-based programs in 3 analyses conducted in 2 studies. In 4 other abstracts, the rates of RSV hospitalization for home health programs and office-based administration did not significantly differ. In a large, 4-season, prospective outcome study, compliant infants had lower RSV hospitalization rates than those who were not compliant under one definition of compliance (doses within 35-day intervals). RSV hospitalization rates were not significantly different using another definition of compliance (receipt of anticipated doses, expected vs. observed rates).In a large survey of 10,390 infants identified from pharmacy dispensing records, RSV hospitalization rates were 1.4% in the compliant group versus 3.1% in the noncompliant group (OR = 2.2, 95% CI = 1.4-3.5, P < 0.001).Adjustment for confounding was not reported in these studies.
CONCLUSION
Medicaid and minority infants were less likely to receive scheduled palivizumab doses. Home-based programs for the administration of palivizumab have been investigated more than other interventions and are associated with improved compliance compared with office-based administration. Compliance with dosing, in general, was associated with lower RSV hospitalization rates. However, these strategies should be further investigated using well-designed studies.

Review
OBJECTIVES
To systematically review the effectiveness and cost-effectiveness of palivizumab for the prevention of respiratory syncytial virus (RSV) in children and examine prognostic factors to determine whether subgroups can be identified with important differences in cost-effectiveness.
DATA SOURCES
Bibliographic databases were searched from inception to March 2007 for literature on the effectiveness and cost-effectiveness of prophylaxis with palivizumab.
REVIEW METHODS
The literature was systematically reviewed and current economic evaluations were analysed to identify which parameters were driving the different cost-effectiveness estimates. A probabilistic decision-analytical model was built to assess the cost-effectiveness of prophylaxis with palivizumab for children at risk of RSV infection and the parameters populated with the best estimates thought most applicable to the UK. We also constructed a new model, the Birmingham Economic Evaluation (BrumEE). Cost-effectiveness analyses were undertaken from both NHS and societal perspectives.
RESULTS
Two randomised controlled trials (RCTs) were identified. Prophylaxis with palivizumab for preterm infants without chronic lung disease (CLD) or children with CLD resulted in a 55% reduction in RSV hospital admission: 4.8% (48/1002) in the palivizumab group and 10.6% (53/500) in the no prophylaxis group (p = 0.0004). Prophylaxis with palivizumab was associated with a 45% reduction in hospitalisation rate RSV among children with coronary heart disease (CHD). Hospitalisation rates for RSV were 5.3% (34/639) in the palivizumab group and 9.7% (63/648) in the no prophylaxis group (p = 0.003). Of existing economic evaluations, 3 systematic reviews and 18 primary studies were identified. All the systematic reviews concluded that the potential costs of palivizumab were far in excess of any potential savings achieved by decreasing hospital admission rates, and that the use of palivizumab was unlikely to be cost-effective in all children for whom it is recommended, but that its continued use for particularly high-risk children may be justified. The incremental cost-effectiveness ratios (ICERs) of the primary studies varied 17-fold for life-years gained (LYG), from 25,800 pounds/LYG to 404,900 pounds/LYG, and several hundred-fold for quality-adjusted life-years (QALYs), from 3200 pounds/QALY to 1,489,700 pounds/QALY for preterm infants without CLD or children with CLD. For children with CHD, the ICER varied from 5300 pounds/LYG to 7900 pounds/LYG and from 7500 pounds/QALY to 68,700 pounds/QALY. An analysis of what led to the discrepant ICERs showed that the assumed mortality rate for RSV infection was the most important driver. The results of the BrumEE confirm that palivizumab does not reach conventional levels of cost-effectiveness in any of the licensed indications if used for all eligible children.
CONCLUSIONS
Prophylaxis with palivizumab is clinically effective for the reducing the risk of serious lower respiratory tract infection caused by RSV infection and requiring hospitalisation in high-risk children, but if used unselectively in the licensed population, the ICER is double that considered to represent good value for money in the UK. The BrumEE shows that prophylaxis with palivizumab may be cost-effective (based on a threshold of 30,000 pounds/QALY) for children with CLD when the children have two or more additional risk factors. Future research should initially focus on reviewing systematically the major uncertainties for patient subgroups with CLD and CHD and then on primary research to address the important uncertainties that remain.

Review
INTRODUCTION
Bronchiolitis is the most common lower respiratory tract infection in infants, occurring in a seasonal pattern, with highest incidence in the winter in temperate climates, and in the rainy season in warmer countries. Bronchiolitis is a common reason for attendance at and admission to hospital.
METHODS AND OBJECTIVES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of prophylactic interventions for bronchiolitis in high-risk children? What are the effects of measures to prevent transmission of bronchiolitis in hospital? What are the effects of treatments for children with bronchiolitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to October 2006 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 40 systematic reviews, RCTs, or observational studies that met our inclusion criteria.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: bronchodilators (oral, inhaled salbutamol, inhaled adrenaline [epinephrine]), chest physiotherapy, corticosteroids, montelukast, nursing interventions (cohort segregation, hand washing, gowns, masks, gloves, and goggles), respiratory syncytial virus immunoglobulins, pooled immunoglobulins, or palivizumab (monoclonal antibody), ribavirin, or surfactants.

Review
BACKGROUND
Respiratory syncytial virus (RSV) bronchiolitis and pneumonia hospitalize hundreds of thousands of infants every year. Treatment is largely supportive therapy, (for example, oxygen, fluids and occasionally mechanical ventilation). Ribavirin, an antiviral agent, is licensed for severe RSV infection, although systematic reviews find it of no benefit. Passive protection against RSV can be achieved through monthly intramuscular injection of the humanized monoclonal anti-RSV antibody palivizumab (Synagis), and yields a 55% reduction in RSV hospitalisation in susceptible infants. This review assesses immunoglobulin treatment of RSV infection rather than its role as a prophylactic measure.
OBJECTIVES
To assess the efficacy of adding human or humanized immunoglobulin therapy to supportive therapy in infants hospitalized with laboratory-determined RSV infection.
SEARCH STRATEGY
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 2006), MEDLINE (1966 to Week 4, January 2006) and EMBASE (1980 to September 2005). We also ran searches of reference lists of relevant trials and review articles and searches of personal files. We did not impose any language restrictions.
SELECTION CRITERIA
We selected randomised controlled trials (RCTs) that compared immunoglobulin treatment with a placebo control in children hospitalized for RSV infection with bronchiolitis or pneumonia or other lower respiratory tract infection (LRTI) with laboratory-documented RSV infection. The primary outcomes of interest were mortality, length of hospitalisation, length of ventilation and oxygen dependence. Secondary outcome measures were pulmonary function and re-hospitalisations for recurrent breathing difficulties in subsequent years. Any adverse effects of the treatments were also noted, for example, hypersensitivity reactions.
DATA COLLECTION AND ANALYSIS
Data were extracted but cross-comparison was not possible due to the shortage of studies and lack comparative measurements.
MAIN RESULTS
Four papers fitted the search criteria. None demonstrated statistically significant benefit of intravenous immunoglobulin (IVIG) treatment added to supportive care compared with supportive care alone. The evidence does not support a role for RSVIG in such a setting, with the doses used in the studies.
AUTHORS' CONCLUSIONS
The evidence on the role of respiratory syncytial virus immunoglobulin (RSVIG) in treating RSV severe infections is limited. Future research might consider using stronger titres of neutralising antibodies; and further analyse severely ill children (who might respond differentially compared to those less ill, but yet hospitalised).

Meta-Analysis Review
Respiratory syncytial virus infection is an important cause of morbidity. Although palivizumab prophylaxis is widely used, it is uncertain whether the cost is justified. A systematic review was therefore performed of the safety, efficacy, and the likely cost effectiveness of prophylaxis for preterm infants in the United Kingdom using a standard search strategy. The only randomised controlled trial identified showed a reduction in hospital admission but no benefit on more serious outcomes. None of the United Kingdom cost studies showed economic benefit for palivizumab prophylaxis. New treatments are rarely cost effective, and, in the absence of a comprehensive economic assessment, continued use for high risk infants may appear justified.

Review
Respiratory syncytial virus, the leading cause of serious upper and lower respiratory tract infection in infants and children, accounts for 125,000 hospitalizations and 450 deaths annually in the United States. It also may predispose to development of asthma later in life. Annual epidemics occur from November to April, and virtually all infants are infected by age 2. Immunity is not durable; hence, reinfection occurs throughout life, although subsequent infections are nearly always mild. Certain populations (eg, premature infants, infants with chronic lung disease, and immunocompromised individuals) are at risk for severe morbidity and have higher risk of mortality. Infection is spread to the nose and eyes by large droplets and direct contact with secretions, and fomites may remain infectious for up to 12 hours. Nosocomial infection is common. The virus infects airway ciliated epithelial cells, spreading by the formation of syncytia. Cellular debris and inflammation cause airway obstruction, hyperinflation, localized atelectasis, wheezing, and impaired gas exchange. Both humoral and cellular immune response are critical to ending the acute infection, but wheezing and reactive airways may persist for as long as 5-10 years after acute infection. No cure exists for respiratory syncytial virus infection, but commonly employed palliative treatments include oxygen, inhaled beta(2) agonists, racemic epinephrine, dornase alfa, systemic and inhaled corticosteroids, inhaled ribavirin, and nasopharyngeal suctioning. Infants suffering severe lower airways disease may require mechanical ventilation. Prophylactic measures include rigorous infection control and administration of polyclonal (RSV-IGIV [respiratory syncytial virus - immunoglobulin intravenous]) and monoclonal (palivizumab) antibodies. The cost of the prophylactic antibody treatment is high; it is cost-effective for only the highest risk patients. Development of a vaccine remains far in the future. Application of evidence-based clinical practice guidelines is making both out-patient and in-patient therapy as effective and economical as possible.

Review
OBJECTIVE
To systematically review all published economic analyses of the only 2 available agents for respiratory syncytial virus immunoprophylaxis in high-risk infants: respiratory syncytial virus immunoglobulin intravenous and palivizumab.
DATA SOURCES
Economic evaluations of respiratory syncytial virus immunoprophylactic agents were identified from the MEDLINE and HealthSTAR databases using various combinations of the following search terms: respiratory syncytial virus immunoglobulin intravenous, palivizumab, cost, and cost-effectiveness. The search was limited to articles published in English between January 1, 1990, and August 31, 2001. Additional studies were obtained by searching bibliographies of all relevant identified articles.
STUDY SELECTION
Only studies that performed an economic analysis of either or both of these agents in an infant population were included. Letters to the editor and commentaries that included informal economic analyses were excluded. Twelve of the 21 identified studies met the selection criteria.
DATA EXTRACTION
Two of us (S.K.-B. and J.D.) independently reviewed the articles and extracted summary information using a standardized abstraction form, with differences resolved by consensus.
DATA SYNTHESIS
Estimates ranging from cost savings to considerable incremental costs per hospitalization avoided with use of either agent were observed across studies. Studies comparing the 2 agents reported mixed results about their relative cost-effectiveness in different infant subgroups. The divergent results may be explained by differences in the study methods and assumptions, but they also reflect the poor quality of some of the economic analyses.
CONCLUSION
In light of the issues identified in this review, providers, payers, and health policymakers need to critically appraise and judiciously interpret cost-effectiveness research on these agents.
