Estimating the economic impact of pneumococcal conjugate,Haemophilus influenzae type b and rotavirus vaccines in India: National and state-level analyses

Background: To support vaccine decision-making we estimated from the societal perspective the potential health impact and costs averted through immunization with three vaccines – Haemophilus influenzae type b (Hib), pneumococcal conjugate vaccine (PCV) and rotavirus vaccine (RVV). Methods: Based on variability in disease burden, strength of health system and economic status, we selected four states in India: Bihar, New Delhi, Maharashtra and Tamil Nadu. We used secondary data sources to estimate the number of under-5 deaths averted from Hib, pneumococcus and rotavirus in each state and back-calculated the total cases averted. We synthesized available data to estimate the disease burden, treatment cost, caretaker productivity loss and vaccine coverage in each state. A Delphi Survey and roundtable among Indian experts was conducted to reach consensus on model inputs. Results: By scaling up coverage of Hib, PCV and RVV, India could save over US$1 billion (uncertainty range: US$0.9–US$2.4 billion) in economic benefits and avert more than 90,000 needless child deaths each year. An estimated US$1 billion (US$0.9–US$2 billion) or 88% of the total amount of cost savings would be attributable to lost productivity due to premature pneumococcal death. Another US$112.8 million (US$105–297 million), or 10% of the total cost would be accounted by costs related to loss of productivity due to disability as a result of these diseases. Treatment costs of Hib, pneumococcal disease and rotavirus gastroenteritis, would account for US$8.4 million (US$4–12 million) or <1% of the total costs of these diseases. Finally, caretaker productivity loss from seeking care would represent US$1.5 million (US$ 1–4.9 million). Cost savings varied by vaccine, coverage scenarios and states. Conclusions: Hib, PCV and RVV vaccine introduction in India can result in immediate benefits to the government and households in terms of savings.     

Lifetime costs of invasive meningococcal disease: A Markov model approach

IntroductionInvasive meningococcal disease (IMD) is an uncommon but life-threatening infectious disease associated with high sequelae rates in young children and an increased risk of mortality in adolescents and young adults. Funding decisions to reject inclusion of new meningococcal serogroup B vaccines on national immunisation schedules have been criticised by IMD patients, their families, paediatricians and charity organisations. We aim to estimate the lifetime costs of IMD with the best available evidence to inform cost-effectiveness analyses.MethodsA Markov model was developed taking healthcare system and societal perspectives. A range of data including age-specific mortality rates, and probabilities of IMD-related sequelae were derived from a systematic review and meta-analysis. All currencies were inflated to year 2017 prices by using consumer price indexes in local countries and converted to US dollars by applying purchasing power parities conversion rates. Expert panels were used to inform the model development process including key structural choices and model validations.ResultsThe estimated lifetime societal cost is US$319,896.74 per IMD case including the direct healthcare cost of US$65,035.49. Using a discount rate of 5%, the costs are US$54,278.51 and US$13,968.40 respectively. Chronic renal failure and limb amputation result in the highest direct healthcare costs per patient. Patients aged < 5 years incur the higher healthcare expenditure compared with other age groups. The costing results are sensitive to the discount rate, disease incidence, acute admission costs, and sequelae rates and costs of brain injuries and epilepsy.ConclusionsIMD can result in substantial costs to the healthcare system and society. Understanding the costs of care can assist decision-making bodies in evaluating cost-effectiveness of new vaccine programs.     

The economic burden of childhood pneumococcal diseases in The Gambia

Background

Streptococcus pneumoniae is a common cause of child death. However, the economic burden of pneumococcal disease in low-income countries is poorly described. We aimed to estimate from a societal perspective, the costs incurred by health providers and families of children with pneumococcal diseases.

Methods

We recruited children less than 5 years of age with outpatient pneumonia, inpatient pneumonia, pneumococcal sepsis and bacterial meningitis at facilities in rural and urban Gambia. We collected provider costs, out of pocket costs and productivity loss for the families of children. For each disease diagnostic category, costs were collected before, during, and for 1 week after discharge from hospital or outpatient visit.

Results

A total of 340 children were enrolled; 100 outpatient pneumonia, 175 inpatient pneumonia 36 pneumococcal sepsis, and 29 bacterial meningitis cases. The mean provider costs per patient for treating outpatient pneumonia, inpatient pneumonia, pneumococcal sepsis and meningitis were US$8, US$64, US$87 and US$124 respectively and the mean out of pocket costs per patient were US$6, US$31, US$44 and US$34 respectively. The economic burden of outpatient pneumonia, inpatient pneumonia, pneumococcal sepsis and meningitis increased to US$15, US$109, US$144 and US$170 respectively when family members’ time loss from work was taken into account.

Conclusion

The economic burden of pneumococcal disease in The Gambia is substantial, costs to families was approximately one-third to a half of the provider costs, and accounted for up to 30 % of total societal costs. The introduction of pneumococcal conjugate vaccine has the potential to significantly reduce this economic burden in this society.

     

The total lifetime costs of smoking

BACKGROUND: Net costs of smoking in a lifetime perspective and, hence, the economic interests in antismoking policies have been questioned. It has been proposed that the health-related costs of smoking are balanced by smaller expenditure due to shorter life expectancy. METHOD: A dynamic (life cycle) method taking differences in life expectancy into account. Main outcome measures were direct and indirect lifetime health costs for ever-smokers and never-smokers, and cost ratios (ever-smokers to never-smokers). The estimations were based on annual disease rates of use of the healthcare services, smoking relative risks, smoking prevalences, and costs. RESULTS: Annual direct and indirect costs of ever-smokers were higher than for never-smokers in all age groups of both genders. The direct and indirect cost ratios were highest at age 45 for women, and at age 35 and 40 for men, respectively. Taking life expectancy differences into account, direct and indirect lifetime health costs for men aged 35, discounted by 5% per year were 66% and 83% higher in ever-smokers than in never-smokers. Corresponding results for women were 74% and 79%, respectively. The results are insensitive to a broad range of relative risk-estimates and discount rates including no discounting. Excess costs of ever-smokers disappear if the inclusion of smoking-related diseases is narrowed to that of previous studies. CONCLUSION: Smoking imposes costs to society even when taking life expectancy into consideration--both in direct and indirect costs.     

The societal cost of vaccine refusal: A modelling study using measles vaccination as a case study

BackgroundIncreasing vaccine hesitancy and refusal poses a challenge to public health as even small reductions in vaccine uptake can result in large outbreaks of infectious diseases. Here we estimate the societal costs of vaccine refusal using measles as a case study.MethodsWe developed a compartmental metapopulation model of measles transmission to explore how the changes in the size and level of social mixing between populations that are “pro-vaccination”, and “anti-vaccination” impacts the burden of measles. Using the projected cases and deaths, we calculated the health, healthcare, direct medical costs, and productivity loss associated with vaccine refusal. Using measles in England as a case study, we quantified the societal costs that each vaccine refusal imposes on society.FindingsWhen there is a high level of mixing between the pro- and anti-vaccination populations, those that refuse to be vaccinated benefit from the herd immunity afforded by the pro-vaccination population. At the same time, their refusal to be vaccinated increases the burden in those that are vaccinated due to imperfect vaccines, and in those that are not able to be vaccinated due to other underlying health conditions. Using England as a case study, we estimate that this translates to a societal loss of GBP 292 million and disease burden of 17 630 quality-adjusted-life-years (sensitivity range 10 594–50 379) over a 20-year time horizon. Of these costs, 26 % are attributable to healthcare costs and 74 % to productivity losses for patients and their carers. This translates to a societal loss per vaccine refusal of GBP 162.21 and 0.01 (0.006–0.03) quality-adjusted-life-years.InterpretationOur findings demonstrate that even low levels of vaccine refusal can have a substantial and measurable societal burden on the population. These estimates can support the value of investment in interventions that address vaccine hesitancy and vaccine refusal, providing not only improved public health but also potential economic benefits to society.     

The socioeconomic costs of mental illness in Spain

Mental illness affects a large number of people in the world, seriously impairing their quality of life and resulting in high socioeconomic costs for health care systems and society. Our aim is to estimate the socioeconomic impact of mental illness in Spain for the year 2002, including health care resources, informal care and loss of labour productivity. A prevalence-based approach was used to estimate direct medical costs, direct non-medical costs, and loss of labour productivity. The total costs of mental illness have been estimated at 7,019 million euros. Direct medical costs represented 39.6% of the total costs and 7.3% of total public healthcare expenditure in Spain. Informal care costs represented 17.7% of the total costs. Loss of labour productivity accounted for 42.7% of total costs. In conclusion, the costs of mental illness in Spain make a considerable economic impact from a societal perspective.      

Significant healthcare burden and life cost of spinal muscular atrophy: real-world data

Objectives

The aim of this study is to quantify the mortality rate, direct healthcare costs, and cumulative life costs of pediatric patients with spinal muscular atrophy (SMA) type 1, type 2, and type 3 born in Hong Kong.

Methods

Data were collected from genetically confirmed SMA patients born in or after 2000 from the Hospital Authority medical database. Patients were followed up from birth until they died, left Hong Kong, reached 18 years, or initiated disease-modifying treatment. Study outcomes included incidence risks of mortality, cumulative direct medical costs—attendances of special outpatient clinics, emergency department, allied health services, and mean length of stay in hospitals over time. Total direct medical costs were calculated as unit costs multiplied by utilization frequencies of corresponding healthcare services at each age.

Results

Seventy-one patients with SMA were included. Over a median follow-up period of 6 years, the overall incidence rate of death was 5.422/100 person-years (95%CI 3.542–7.945/100 person-years). 67.7% and 11% of deaths occurred in SMA1 and SMA2 groups, respectively. The median age of death was 0.8 years in SMA1 and 10.9 years in SMA2. The mean cumulative direct medical costs in overall SMA, SMA1, SMA2 and SMA3 groups per patient were US$935,570, US$2,393,250, US$413,165, and US$40,735, respectively.

Interpretation: Our results confirmed a significantly raised mortality and extremely high healthcare burden for patients with SMA especially SMA type 1 and 2 without disease-modifying treatment. Study evaluating health and economic impact of newborn screening and early treatment is needed.

     

Economic burden of seasonal influenza in the United States

BackgroundSeasonal influenza is responsible for a large disease and economic burden. Despite the expanding recommendation of influenza vaccination, influenza has continued to be a major public health concern in the United States (U.S.). To evaluate influenza prevention strategies it is important that policy makers have current estimates of the economic burden of influenza.ObjectiveTo provide an updated estimate of the average annual economic burden of seasonal influenza in the U.S. population in the presence of vaccination efforts.MethodsWe evaluated estimates of age-specific influenza-attributable outcomes (ill-non medically attended, office-based outpatient visit, emergency department visits, hospitalizations and death) and associated productivity loss. Health outcome rates were applied to the 2015 U.S. population and multiplied by the relevant estimated unit costs for each outcome. We evaluated both direct healthcare costs and indirect costs (absenteeism from paid employment) reporting results from both a healthcare system and societal perspective. Results were presented in five age groups (<5 years, 5–17 years, 18–49 years, 50–64 years and ≥65 years of age).ResultsThe estimated average annual total economic burden of influenza to the healthcare system and society was $11.2 billion ($6.3–$25.3 billion). Direct medical costs were estimated to be $3.2 billion ($1.5–$11.7 billion) and indirect costs $8.0 billion ($4.8–$13.6 billion). These total costs were based on the estimated average numbers of (1) ill-non medically attended patients (21.6 million), (2) office-based outpatient visits (3.7 million), (3) emergency department visit (0.65 million) (4) hospitalizations (247.0 thousand), (5) deaths (36.3 thousand) and (6) days of productivity lost (20.1 million).ConclusionsThis study provides an updated estimate of the total economic burden of influenza in the U.S. Although we found a lower total cost than previously estimated, our results confirm that influenza is responsible for a substantial economic burden in the U.S.     

Assessment of Total Economic Burden of Chronic Hepatitis B (CHB)-Related Diseases in Beijing and Guangzhou, China

Objective:  To estimate the total annual cost due to Chronic Hepatitis B (CHB)-related diseases imposed on each patient and his/her family in Beijing and Guangzhou, China.
Methods:  Economic burden of CHB-related diseases (CHB, compensated cirrhosis, decompensated cirrhosis, and hepatocellular carcinoma) were examined. A retrospective cohort of 328 patients in Beijing and 271 in Guangzhou were identified to obtain their socioeconomic status, utilization and costs of treatment, and work loss days due to illness with a structured questionnaire. Costs of hospitalization were extracted from databases of two hospitals in Beijing and Guangzhou Social Insurance Information System, respectively. The outpatient expenditure per patient was measured through the rate of outpatient visits and average cost per visit reported by the patients, while the inpatient cost was calculated through annual rate of hospitalization and average expenditure for different types of hospitals. Self medication and direct nonmedical cost were also reported. The Human Capital Approach was employed to measure the work loss cost.
Results:  The total annual cost per patient for CHB, compensated cirrhosis, decompensated cirrhosis, and hepatocellular carcinoma were US$1636, US$2722, US$4611, and US$6615 in Beijing, and US$1452, US$2065, US$4290 and US$6054 in Guangzhou, respectively.
Conclusion:  This study confirms that CHB-related diseases impose a substantial economic burden on patients, families, and the society in China urban areas. The study demonstrates increasing health-care costs related to disease progression and provides useful information on cost of treatment and work loss for different disease states, which can be further utilized in cost-effectiveness evaluation.     

Medical costs and productivity losses due to interpersonal and self-directed violence in the United States

BACKGROUND: Violence-related injuries, including suicide, adversely affect the health and welfare of all Americans through premature death, disability, medical costs, and lost productivity. Estimating the magnitude of the economic burden of violence is critical for understanding the potential amount of resources that can be saved if cost-effective violence prevention efforts can be broadly applied. From 2003 to 2005, the lifetime medical costs and productivity losses associated with medically treated injuries due to interpersonal and self-directed violence occurring in the United States in 2000 were assessed. METHODS: Several nationally representative data sets were combined to estimate the incidence of fatal and nonfatal injuries due to violence. Unit medical and productivity costs were computed and then multiplied by corresponding incidence estimates to yield total lifetime costs of violence-related injuries occurring in 2000. RESULTS: The total costs associated with nonfatal injuries and deaths due to violence in 2000 were more than $64.8 [corrected] billion. Most of this cost ($64.4 billion or 92%) was due to lost productivity. However, an estimated $5.6 billion was spent on medical care for the more than 2.5 million injuries due to interpersonal and self-directed violence. CONCLUSIONS: The burden estimates reported here provide evidence of the large health and economic burden of violence-related injuries in the U.S. But the true burden is likely far greater and the need for more research on violence surveillance and prevention are discussed.     

Depression: cost-of-illness studies in the international literature, a review

BACKGROUND: Depression is one of the most ancient and common diseases of the human race and its burden on society is really impressive. This stems both from the epidemiological spread (lifetime prevalence rate, up to 30 years of age, was estimated as greater than 14.4% by Angst et al.) and from the economic burden on healthcare systems and society, but also as it pertains to patient well-being. AIMS OF THE STUDY: The scope of this review was to examine studies published in the international literature to describe and compare the social costs of depression in various countries. METHODS: A bibliographic search was performed on international medical literature databases (Medline, Embase), where all studies published after 1970 were selected. Studies were carefully evaluated and only those that provided cost data were included in the comparative analysis; this latter phase was conducted using a newly developed evaluation chart. RESULTS: 10 abstracts were firstly selected; 46 of them underwent a subsequent full paper reading, thus providing seven papers, which were the subject of the in-depth comparative analysis: three studies investigated the cost of depression in the USA, three studies in the UK and one study was related to Italy. All the studies examined highlight the relevant economic burden of depression; in 1990, including both direct and indirect costs, it accounted for US$ 43.7 billion in the US (US$ 65 billion, at 1998 prices) according to Greenberg and colleagues, whilst direct costs accounted for ￡417 million in the UK (or US$ 962.5 million, at 1998 prices), according to Kind and Sorensen. Within direct costs, the major cost driver was indeed hospitalization, which represented something in between 43 and 75% of the average per patient cost; conversely, drug cost accounted for only 2% to 11% in five out of seven studies. DISCUSSION: Indeed, our review suggests that at the direct cost level, in both the United States and the United Kingdom, the burden of depression is remarkable, and this is confirmed by a recent report issued by the Pharmaceutical Research and Manufacturers Association (PhRMA) where prevalence and cost of disease were compared for several major chronic diseases, including Alzheimer, asthma, cancer, depression, osteoporosis, hypertension, schizophrenia and others: in this comparison, depression is one of the most significant diseases, ranked third by prevalence and sixth in terms of economic burden. Moreover, in terms of the average cost per patient, depression imposes a societal burden that is larger than other chronic conditions such as hypertension, rheumatoid arthritis, asthma and osteoporosis. The application of economic methods to the epidemiological and clinical field is a relatively recent development, as evidenced by the finding that, out of the seven studies examined, three refer to the US environment, three to the UK and one to Italy, while nothing was available about the cost of depression for large countries such as France, Germany, Spain, Japan and others. IMPLICATION FOR HEALTH CARE PROVISION AND USE: The high incidence of hospitalization, and the finding that drug cost represents only a minor component of the total direct cost of the disease, suggests that room is still available for disease management strategies that, while effectively managing the patient's clinical profile, could also improve health economic efficiency. IMPLICATION FOR HEALTH POLICIES: Disease management strategies, with particular emphasis on education, should be targeted not only at patients and medical professionals but also at health decision makers in order "to encourage effective prevention and treatment of depressive illness". IMPLICATIONS FOR FURTHER RESEARCH: Cost of illness studies are a very useful tool allowing cost data comparisons across countries and diseases: for this reason, we suggest that further research is needed especially in some western European countries to assess the true economic burden of depression on societies.     

The total lifetime health cost savings of smoking cessation to society

BACKGROUND: Smoking cessation has major immediate and long-term health benefits. However, ex-smokers' total lifetime health costs and continuing smokers' costs remain uncompared, and hence the economic savings of smoking cessation to society have not been determined. METHODS: The economic effects of smoking cessation in a lifetime perspective have been examined by comparing the health costs of continuing smokers and ex-smokers by quantity of daily tobacco consumption, age, gender and disease group, while taking differences in life expectancy and the reductions in relative risks after cessation into account. RESULTS: The total lifetime health cost savings of smoking cessation are highest at the younger ages. Although the economic savings vary with age at quitting, gender and quantity of daily tobacco consumption, all ex-smoking men and women who quit smoking at the age of 35 to 55 years generate sizeable total lifetime cost savings. At older ages, the total lifetime health cost savings of smoking cessation are of little economic consequence to the society. The total, direct and productivity lifetime cost savings of smoking cessation in moderate smokers who quit smoking at the age of 35 years are 24,800 euros, 7600 euros, and 17,200 euros in men, and 34,100 euros, 12,200 euros, and 21,800 euros in women, respectively. CONCLUSIONS: Lifetime health cost savings of smoking cessation to society are substantial at younger ages, in terms of both direct and productivity costs.     

Economic burden and health-related quality-of-life among infants with respiratory syncytial virus infection: A multi-country prospective cohort study in Europe

BackgroundRespiratory syncytial virus (RSV) causes a considerable disease burden in young children globally, but reliable estimates of RSV-related costs and health-related quality-of-life (HRQoL) are scarce. This study aimed to evaluate the RSV-associated costs and HRQoL effects in infants and their caregivers in four European countries.MethodsHealthy term-born infants were recruited at birth and actively followed up in four European countries. Symptomatic infants were systematically tested for RSV. Caregivers recorded the daily HRQoL of their child and themselves, measured by a modified EQ-5D with Visual Analogue Scale, for 14 consecutive days or until symptoms resolved. At the end of each RSV episode, caregivers reported healthcare resource use and work absenteeism. Direct medical costs per RSV episode were estimated from a healthcare payer’s perspective and indirect costs were estimated from a societal perspective. Means and 95% confidence intervals (CI) of direct medical costs, total costs (direct costs + productivity loss) and quality-adjusted life-day (QALD) loss per RSV episode were estimated per RSV episode, as well as per subgroup (medical attendance, country).ResultsOur cohort of 1041 infants experienced 265 RSV episodes with a mean symptom duration of 12.5 days. The mean (95% CI) cost per RSV episode was €399.5 (242.3, 584.2) and €494.3 (317.7, 696.1) from the healthcare payer’s and societal perspective, respectively. The mean QALD loss per RSV episode of 1.9 (1.7, 2.1) was independent of medical attendance (in contrast to costs, which also differed by country). Caregiver and infant HRQoL evolved similarly.ConclusionThis study fills essential gaps for future economic evaluations by prospectively estimating direct and indirect costs and HRQoL effects on healthy term infants and caregivers separately, for both medically attended (MA) and non-MA laboratory-confirmed RSV episodes. We generally observed greater HRQoL losses than in previous studies which used non-community and/or non-prospective designs.     

Cost‐effectiveness of aftercare services for people with severe mental disorders: an analysis parallel to a randomised controlled clinical trial in Iran

Aftercare services are not part of the usual care for people with severe mental disorders in Iran. This study was performed to assess the cost‐effectiveness of aftercare services, including telephone follow‐up or home visit, in addition to caregivers’ education and training of social skills, for all subjects during the 20 months after hospital discharge. An economic evaluation was performed along with a registered randomised controlled trial (IRCT201009052557N2) on two groups of 60 persons recruited between 2010 and 2012. Intervention's effectiveness was measured by psychopathology and quality of life indicators. Cost‐effectiveness and cost‐utility were analysed from the societal and Ministry of Health (MoH) perspectives. All indicators of psychopathology, quality of life and satisfaction with services in the intervention group were significantly different from the control group. Mean intervention costs was US$674 (95% confidence interval [CI]: 572–776) per subject in the intervention group. Average total direct costs were US$1445 (95% CI: 1086–1804) and US$1640 (95% CI: 1087–2093) per subject in the intervention and control groups respectively. From the societal perspective, intervention had more effects with lower costs. The ratios for incremental cost‐effectiveness was US$8399.1 (95% CI: 8178.2–8620.0) per quality‐adjusted life year (QALY) gained from the MoH perspective for 20 months of follow‐up. This study showed that aftercare services can create opportunities to use hospital beds more efficiently for unmet needs of people with psychiatric disorders. Indirect and intangible costs were not considered in this study, if taken into account, they are likely to further increase the efficiency of intervention.     

Cost-effectiveness of Haemophilus influenzae type b vaccine in Vietnam

BackgroundWith GAVI support, Vietnam introduced Haemophilus influenzae type b (Hib) vaccine in 2010 without evidence on cost-effectiveness. We aimed to analyze the cost-effectiveness of Hib vaccine from societal and governmental perspectives.MethodWe constructed a decision-tree cohort model to estimate the costs and effectiveness of Hib vaccine versus no Hib vaccine for the 2011 birth cohort. The disease burden was estimated from local epidemiologic data and literature. Vaccine delivery costs were calculated from governmental reports and 2013 vaccine prices. A prospective cost-of-illness study was conducted to estimate treatment costs. The human capital approach was employed to estimate productivity loss. The incremental costs of Hib vaccine were divided by cases, deaths, and disability-adjusted life years (DALY) averted. We used the WHO recommended cost-effectiveness thresholds of an intervention being highly cost-effective if incremental costs per DALY were below GDP per capita.ResultFrom the societal perspective, incremental costs per discounted case, death and DALY averted were US$ 6252, US$ 26,476 and US$ 1231, respectively; the break-even vaccine price was US$ 0.69/dose. From the governmental perspective, the results were US$ 6954, US$ 29,449, and US$ 1373, respectively; the break-even vaccine price was US$ 0.48/dose. Vietnam's GDP per capita was US$ 1911 in 2013. In deterministic sensitivity analysis, morbidity and mortality parameters were among the most influential factors. In probabilistic sensitivity analysis, Hib vaccine had an 84% and 78% probability to be highly cost-effective from the societal and governmental perspectives, respectively.ConclusionHib vaccine was highly cost-effective from both societal and governmental perspectives. However, with GAVI support ending in 2016, the government will face a six-fold increase in its vaccine budget at the 2013 vaccine price. The variability of vaccine market prices adds an element of uncertainty. Increased government commitment and improved resource allocation decision making will be necessary to retain Hib vaccine.     

The economic and health impact of rare diseases: A meta-analysis

ObjectiveLack of medical and scientific knowledge on rare diseases (RD) often translates into limited research on them and a subsequent lack of understanding of their economic impact. This meta-analysis aims to fill this gap by evaluating the economic impact of RDs and exploring potential factors associated with the societal burden of RD.MethodsStudies published between January 2010 and February 2017 were identified by searches in the PubMed platform. Thirty eligible studies were identified for inclusion, and nineteen studies were included in the meta-analysis and outcomes were explored. The cost categories include direct healthcare costs, direct non-healthcare formal costs, and direct non-healthcare informal costs. The patients’ health-related quality of life (QoL) dimensions examined include EQ-5D scores, VAS scores and Barthel index, and the carers’ utility outcomes include EQ-5d scores, VAS scores and Zarit scale. Random effects meta-regression models were used for modelling the impact of study and societal characteristics on cost.ResultsAcross all RDs, mean direct healthcare (DH) costs ($16,513) account for the majority of direct costs (mainly driven by drug costs), followed by mean direct healthcare informal (€15,557) and mean direct healthcare formal (€4,579) costs. Body system affected by the RD, Gross Domestic Product (GDP) per capita and public health expenditure in country of study were the most significant determinants in predicting cost. In regards to QoL outcomes, patients with musculoskeletal diseases seem to have the lowest quality of life across EQ-5D scores, VAS scores and Barthel index. The burden on caregivers seemed to be associated with Autoimmune, followed by Musculoskeletal and Respiratory conditions.ConclusionsThis meta-analysis highlights the significant burden of RDs on the health care system and explicitly provides evidence for the magnitude of this impact. Such estimates are necessary to further the debate on priority setting around RDs and their comparison with other chronic diseases. Nevertheless, the large degree of cost variability across RDs might suggest that the use of umbrella terms to raise awareness around RDs’ societal impact might not be warranted.     

Enhancing the comparability of costing methods: cross-country variability in the prices of non-traded inputs to health programmes

Background

Given the size of the HIV epidemic in South Africa and other developing countries, scaling up antiretroviral treatment (ART) represents one of the key public health challenges of the next decade. Appropriate priority setting and budgeting can be assisted by economic data on the costs and cost-effectiveness of ART. The objectives of this research were therefore to estimate HIV healthcare utilisation, the unit costs of HIV services and the cost per life year (LY) and quality adjusted life year (QALY) gained of HIV treatment interventions from a provider's perspective.

Methods

Data on service utilisation, outcomes and costs were collected in the Western Cape Province of South Africa. Utilisation of a full range of HIV healthcare services was estimated from 1,729 patients in the Khayelitsha cohort (1,146 No-ART patient-years, 2,229 ART patient-years) using a before and after study design. Full economic costs of HIV-related services were calculated and were complemented by appropriate secondary data. ART effects (deaths, therapy discontinuation and switching to second-line) were from the same 1,729 patients followed for a maximum of 4 years on ART. No-ART outcomes were estimated from a local natural history cohort. Health-related quality of life was assessed on a sub-sample of 95 patients. Markov modelling was used to calculate lifetime costs, LYs and QALYs and uncertainty was assessed through probabilistic sensitivity analysis on all utilisation and outcome variables. An alternative scenario was constructed to enhance generalizability.

Results

Discounted lifetime costs for No-ART and ART were US$2,743 and US$9,435 over 2 and 8 QALYs respectively. The incremental cost-effectiveness ratio through the use of ART versus No-ART was US$1,102 (95% CI 1,043-1,210) per QALY and US$984 (95% CI 913-1,078) per life year gained. In an alternative scenario where adjustments were made across cost, outcome and utilisation parameters, costs and outcomes were lower, but the ICER was similar.

Conclusion

Decisions to scale-up ART across sub-Saharan Africa have been made in the absence of incremental lifetime cost and cost-effectiveness data which seriously limits attempts to secure funds at the global level for HIV treatment or to set priorities at the country level. This article presents baseline cost-effectiveness data from one of the longest running public healthcare antiretroviral treatment programmes in Africa that could assist in enhancing efficient resource allocation and equitable access to HIV treatment.     

The annual impact of seasonal influenza in the US: measuring disease burden and costs

BACKGROUND: Despite preventive efforts, influenza epidemics are responsible for substantial morbidity and mortality every year in the United States (US). Vaccination strategies to reduce disease burden have been implemented. However, no previous studies have systematically estimated the annual economic burden of influenza epidemics, an estimate necessary to guide policy makers effectively. OBJECTIVE: We estimate age- and risk-specific disease burden, and medical and indirect costs attributable to annual influenza epidemics in the United States. METHODS: Using a probabilistic model and publicly available epidemiological data we estimated the number of influenza-attributable cases leading to outpatient visits, hospitalization, and mortality, as well as time lost from work absenteeism or premature death. With data from health insurance claims and projections of either earnings or statistical life values, we then estimated healthcare resource utilization associated with influenza cases as were their medical and productivity (indirect) costs in $2003. RESULTS: Based on 2003 US population, we estimated that annual influenza epidemics resulted in an average of 610,660 life-years lost (undiscounted), 3.1 million hospitalized days, and 31.4 million outpatient visits. Direct medical costs averaged $10.4 billion (95% confidence interval [C.I.], $4.1, $22.2) annually. Projected lost earnings due to illness and loss of life amounted to $16.3 billion (C.I., $8.7, $31.0) annually. The total economic burden of annual influenza epidemics using projected statistical life values amounted to $87.1 billion (C.I., $47.2, $149.5). CONCLUSIONS: These results highlight the enormous annual burden of influenza in the US. While hospitalization costs are important contributors, lost productivity from missed work days and lost lives comprise the bulk of the economic burden of influenza.     

Economic burden of influenza illness among children under 5 years in Suzhou,China: Report from the cost surveys during 2011/12 to 2016/17 influenza seasons

BackgroundData are limited on the economic burden of seasonal influenza in China. We estimated the cost due to influenza illness among children < 5-year-old in Suzhou, China.MethodsThis study adopted a societal perspective to estimate direct medical cost, direct non-medical cost, and indirect cost related to lost productivity. Data to calculate costs and rates of three influenza illness outcomes (non-medically attended, outpatient and hospitalization) were collected from prospective community-based cohort studies and hospital-based enhanced laboratory-confirmed influenza surveillance in Suzhou during the 2011/12 to 2016/17 influenza seasons. We used mean cost-per-episode, annual incidence rates of episodes of each outcome, and annual population size to estimate the total annual economic burden of influenza illnesses among children < 5-year-old for Suzhou. All costs were reported in 2017 U.S. dollars.ResultsThe mean cost-per-episode (standard deviation) was $9.92 (13.26) for non-medically attended influenza, $161.05 (176.98) for influenza outpatient illnesses, and $1425.95 (603.59) for influenza hospitalizations. By applying the annual incidence rates to the population size, we estimated an annual total of 4,919 episodes of non-medically attended influenza, 21,994 influenza outpatient, and 2,633 influenza hospitalization. Total annual economic burden of influenza to society among children < 5-year-old in Suzhou was $7.37 (95% confidence interval, 6.9–7.8) million, with estimated costs for non-medically attended influenza of $49,000 (46,000–52,000), influenza outpatients $3.5 (3.3–3.8) million, and influenza hospitalizations $3.8 (3.6–3.9) million. Among outpatients, the indirect cost was 36.3% ($1.3 million) of total economic burden, accounting for 21,994 days of lost productivity annually. Among inpatients, the indirect cost was 22.1% ($829,000), accounting for 18,431 days of lost productivity annually.ConclusionsOur findings show that influenza in children < 5-year-oldcauses substantial societal economic burden in Suzhou, China. Assessing the potential economic benefit of increasing influenza vaccination coverage in this population is warranted.
