A Systemic Review of Economic Evaluation of Interventions for High Risk Young People
Protocol for the economic evaluation of a complex intervention to better the mental health of maltreated infants and children in foster intendance in the U.k. (The Best? services trial)
Abstract
Introduction Children who have experienced abuse and neglect are at increased risk of mental and physical health problems throughout life. This places an enormous burden on individuals, families and society in terms of health services, education, social intendance and judiciary sectors. Evidence suggests that early intervention tin mitigate the negative consequences of child maltreatment, exerting long-term positive effects on the wellness of maltreated children entering foster care. Even so, testify on cost-effectiveness of such complex interventions is limited. This protocol describes the first economic evaluation of its kind in the United kingdom.
Methods and analysis An economic evaluation aslope the Best Services Trial (BeST?) has been prospectively designed to identify, measure and value key resource and outcome impacts arising from the New Orleans intervention model (NIM) (an infant mental health service) compared with case direction (CM) (enhanced social work services equally usual). A inside-trial economic evaluation and long-term model from a National Wellness Service/Personal Social Service and a broader societal perspective volition be undertaken aslope the National Institute for Health Research (NIHR)–Public Health Research Unit (PHRU)-funded randomised multicentre All-time?. BeST? aims to evaluate NIM compared with CM for maltreated children inbound foster care in a UK context. Collection of Paediatric Quality of Life Inventory (PedsQL) and the recent mapping of PedsQL to EuroQol-v-Dimensions (EQ-5D) volition facilitate the estimation of quality-adjusted life years specific to the infant population for a price–utility analysis. Other effectiveness outcomes volition be incorporated into a price-effectiveness analysis (CEA) and cost-consequences analysis (CCA). A long-term economical model and multiple economic evaluation frameworks volition provide decision-makers with a comprehensive, multiperspective guide regarding cost-effectiveness of NIM. The long-term population wellness economical model volition be adult to synthesise trial data with routine linked data and key government sector parameters informed by literature. Methods guidance for population wellness economic evaluation will exist adopted (lifetime horizon, 1.5% discount charge per unit for costs and benefits, CCA framework, multisector perspective).
Ethics and dissemination Ethics approval was obtained by the Westward of Scotland Ethics Committee. Results of the main trial and economic evaluation will be submitted for publication in a peer-reviewed journal every bit well as published in the peer-reviewed NIHR journals library (Public Wellness Research Programme).

Introduction
There is evidence that maltreated children are at greater risk for lifelong health and social issues, including mental illnesses, criminality, chronic diseases, disability1 and poorer quality of life.2 A history of child maltreatment is too associated with lower developed levels of economic well-beingness beyond a wide range of metrics, including higher levels of economical inactivity, lower occupational status, lower earnings and lower expected earnings.iii Existing enquiry suggests a ripple effect acquired by lower educational accomplishment, higher levels of truancy and expulsion reducing pinnacle earning chapters by US$5000 a year4 or an average lifetime toll of US$210 012 per person1 when considering productivity losses and costs from healthcare, child welfare, criminal justice and special didactics.
Early interventions to promote the health and well-being of children accept been shown to help mitigate the negative consequences of child maltreatment and have long-term positive furnishings on the wellness of maltreated children.five Services are required that provide support to families as soon every bit they need it, and provide early on permanency decisions.6 Interventions that exhibit these characteristics are most probable to improve children's mental health and well-being and reduce health and societal costs over the long term through increased likelihood that children will take college educational achievements, successful lives and be less likely to be dependent on the land. In the brusque run, costs will be lowered past reducing social workers' time, fugitive several repeated decisions due to multiple placements.6
Several reports have highlighted the inadequacies of the United kingdom of great britain and northern ireland's care system and the high costs associated with implementing new services6 too as the increasing costs that are associated with cycling placements or returns to intendance.seven Additionally, existing analyses have emphasised the challenges in conducting economic evaluations of interventions aimed at improving outcomes for maltreated children, which include the need for a long-term perspective, accounting for the context-specific nature of interventions,8 and overcoming obstacles of cross-comparison due to variations in methods, samples etc.9
New Orleans intervention model for baby mental health in Glasgow and South London
The New Orleans intervention model (NIM) (box 1) is based on the Tulane Infant Team programme10 and is being implemented in the United kingdom through the collaboration between voluntary services National Society for the Prevention of Cruelty to Children (NSPCC), social (various City Councils including Glasgow and Croydon) and health services (including National Wellness Service (NHS) Greater Glasgow and Clyde and South London and Maudsley Trust) in the UK. A preliminary economic model exploring the likely costs and consequences of implementing the NIM in Glasgow concluded that NIM would be more costly, but the probability of repeated episodes is likely to autumn significantly, every bit it involves both assessment and treatment phases as opposed to the assessment only nature of typical social services case management (CM).11
Box i
The New Orleans intervention model (NIM) intervention
NIM is an intervention which uses an infant mental health approach aiming to improve the quality of permanent placement decisions with the aim of improving outcomes for young children. The Tulane Infant Team, who adult NIM, assesses the mental health of every child under 5 years on reception into foster care and quality of the relationships between the child and their parents. A tailored intervention is and then offered to each family aiming to improve parent–child relationships and child mental health. These assessments and the degree of modify achieved through intervention inform recommendations to the legal organization about the permanent future care of the child. Where change has been achieved which indicates it is safe, children are rehabilitated back to the birth family. If not, the recommendation is adoption or long-term care.
The NIM intervention volition be delivered, in each site, past a multidisciplinary team comprising a kid and boyish psychiatrist, clinical psychologists, social workers therapists and authoritative staff. Each member of clinical staff will receive specific training in assessment techniques and treatment delivery from the New Orleans and/or Glasgow squad.
Participants randomised to NIM will be asked to accept part in a detailed zipper-informed cess involving each actual and potential caregiver. The assessment is manualised, standardised and uses structured interviews, self-report measures and observations.ten An intervention will so be tailored for every family, cartoon on a small range of human relationship-based therapeutic techniques all of which comply with the recommendations of a meta-assay that examined ways of improving parental sensitivity.50 Parents will also be referred as required to other agencies for help with substance misuse, mental health issues or intrafamilial violence. The aim is to have the safest better outcome for the child, be this a recommendation of rehabilitation to birth family unit or adoption.51 Making well-informed permanent placement recommendations within vi–12 months could optimise physical, mental and social development, while as well assuasive parent the opportunity to make changes if possible.
The Best Services Trial
The Best Services Trial (Best?), led by the University of Glasgow, is a continuation and expansion of an internal airplane pilot randomised controlled trial (RCT) that commenced December 2011 in Glasgow. During this preliminary written report, approximately two-thirds of children coming into care in Glasgow were recruited and randomised into receiving the NIM or enhanced CM.i The All-time? volition keep every bit a definitive multicentre RCT expanding on the piece of work currently taking identify in Glasgow including an additional site in South London, England. Including a London site volition increment generalisability of the findings which may have important policy implications for the UK. Details of the main trial study protocol are bachelor elsewhere.12
NIM has demonstrated preliminary bear witness of effectiveness in USA,x 13 but its effectiveness and cost-effectiveness in terms of improving the mental health of children coming into care following maltreatment is unknown in a Great britain setting. The absence of whatever standardised mental health services for maltreated infants in the United kingdom which favours a 'social care'-oriented system, makes this an interesting case to analyse effectiveness and cost-effectiveness of the NIM intervention. Initial US evidence suggests positive consequences of placement stability and improvements in infant mental health, besides as longer-term resulting benefits to academic performance, employability, and reduction in teenage delinquency and crime.11
Aim
The BeST? trial aims to evaluate the effectiveness and price-effectiveness of NIM in improving the mental health of maltreated infants and children in foster care, the relationship betwixt these children and their primary caregivers, and the timeliness of permanent placement decisions, compared with CM. The aim of the economical evaluation alongside the Best? RCT is to found the short-term and long-term toll-effectiveness of NIM compared with CM from both a health and societal perspective.
Methods and analysis
All-time? is a multisite RCT taking place in Glasgow and London, UK. These sites are characterised by a high level of impecuniousness and a large number of children coming to foster care, thus representing an interesting location to analyse effectiveness and price-effectiveness of the NIM intervention.
Families who have a child entering care at either site, aged 0–60 months, will be randomised to receive NIM or CM. Information collection captures data regarding whoever the primary carer is at the time of follow-up (whether that be birth parent(s), grandparents, foster carers or adopted parents) and it will take place at baseline and at follow-upwardly (fifteen months and 2.5 years). The master effect for the trial is the Strengths and Difficulties Questionnaire (SDQ) at two.5 years: a sample size of 462 will have ninety% ability to notice an event size of 0.35, allowing for 25% loss to follow-up in this intention-to-treat analysis.12
The economic evaluation volition involve a within-trial economical analysis and a population health economic model considering the long-term impact of the NIM intervention on several regime sectors where a mental wellness intervention of this kind is probable to take an impact.
Within-trial analysis
The within-trial analysis will investigate the cost-effectiveness of NIM compared with CM through a number of unlike analyses. The primary inside-trial analysis will be a price–utility analysis (CUA) which will guess the incremental cost per quality-adapted life yr (QALY) of NIM compared with CM. QALYs will be generated via measurement of utility values using the Paediatric Quality of Life Inventory (PedsQL)14 kid health-related quality of life (HRQoL) instrument mapped to the EQ-5D (ie, a widely used instrument to assess HRQoL) to generate utility values.15 Furthermore, the aforementioned authors who mapped the PedsQL to the EQ-5D are currently developing a preference-based index for the PedsQL. Every bit this is ongoing enquiry, the inclusion of this preference-based alphabetize will be explored at time of assay, if available. This mapping of the PedsQL to QALY represents a strength of this project, since it will allow the estimation of kid-specific health utilities.15 Additionally, the incremental cost per unit of measurement improvement using the effectiveness effect SDQ16 will be explored. Within such a technical efficiency framework, there is no accepted threshold value for unit of measurement changes in the SDQ, nonetheless, the costs required to reduce full difficulties scores (and remove birthday) volition exist reported.
Increasingly, in complex public wellness evaluation research, there are questions well-nigh whether all relevant benefits can be captured in a single summary outcome measure such every bit QALY or unit of measurement of 'effectiveness' or net benefit approach17 which is why the use of a cost-consequence analysis (CCA) framework is being recommended for such economical evaluations.18 Other outcomes from the trial such as the Parent–Infant Relationship Global Cess Scale (an observational measure that is independently rated blind to group allotment) volition be included in the CCA so that all costs and outcomes from the trial can be displayed transparently for determination-makers to consider trade-offs themselves. This format can be especially useful in capturing broader intervention effects not contained within the psychometric properties of the PedsQL or SDQ.
These analyses volition adhere to practiced practice guidelines for conducting economic evaluations alongside clinical trials, reporting standards and the most contempo National Institute for Wellness and Care Excellence (Nice) public health reference case.18–20 The within-trial assay volition adopt the perspective of the NHS and Personal Social Services (PSS) and examine the costs to these sectors specifically. Additionally, a wider public sector perspective will be explored which volition include societal resources such as contacts with the police, residential or respite care, and costs to the family in terms of additional kid care.
Resource use
Identification of resource utilise
The identification of the resources used within such a complex intervention relates to the identification of multiple components involved in the delivery of NIM and CM interventions, as well as identification of the costs incurred and cost savings arising as a effect of the intervention and the command.
The costs borne by the wellness and social intendance (NHS/PSS) to evangelize the NIM and the CM interventions include the time spent by individuals delivering the NIM and CM services, such as medical professionals and service direction (administrators, team leaders, squad members, area social workers, psychologists and psychiatrists). In addition, the consequential health and social services used past participants (mental health services, admissions to infirmary, addiction/domestic violence services etc) will be likewise taken into account.
The time spent by nascency parents and other primary caregivers' involvement in NIM or CM as well as law contacts, mean solar day intendance, schoolhouse or plant nursery usage will be incorporated into the calculation of scenario analyses to provide a broader societal perspective of the costs of these services.
Measurement of resources use
Data on the time spent by diverse practitioners (eg, social workers, administrators, psychologists etc) in providing each service volition be measured from the services directly. Both NIM and CM collect information virtually each contact the service has with each child. This data includes the purpose, place, length of contacts and all individuals present at the meeting. The services besides collect data about other services that the kid and their nascency parents or other primary caregivers were recommended to nourish (eg, addictions support, women'southward support etc).
New Orleans intervention model
Total costs for NIM will comprise the cost of delivering NIM plus resource used during the trial period. To make up one's mind the cost of the intervention an approximate care pathway was defined with the help of key social care and infant mental health experts. This includes: (i) a standardised cess taking approximately 12 weeks; (ii) treatment which could consist of up to six different types of intervention; (3) post-handling meetings; (4) debriefing and (5) whatever other substantial activeness such as a court hearing or court omnipresence. Data on the use of this service are collected past the NSPCC'southward information collection system. This system routinely collects data on each contact for each child including the practitioner providing the service, all the individuals who were in attendance and the duration of the contact. This arrangement is reliant on the routine input from NSPCC staff members and also collects information about other services that were recommended by practitioners for the nascency parents/other chief caregivers. An example of the data that is extracted is given in online supplementary appendix ane.
Supplementary file one
The NSPCCs information collection system does not collect the key resource use items of training and authoritative staff time for each contact with or for the kid in question. An informal Delphi technique volition be used to guess the likely average, minimum, and maximums of the preparation and authoritative time that goes into each contact, precontact and postcontact. NIM team members in Glasgow and London volition be surveyed individually to provide their estimates, and those estimates will be combined to provide averages with uncertainty estimates on either side. The team will then be consulted once again with these estimates to come up to a final consensus.
Case management
CM provides social piece of work service as usual, enhanced through the standardisation that comes with the RCT. This includes regular multiagency meetings that troubleshoot problems with services and private cases. Data on date, the nature of the contact, elapsing, attendees, and if they were referred to an exterior service are all collected electronically and held on a shared drive equally multiple people may work on existing cases. Duration includes time spent before (preparing and setting up the meeting), during and after (writing up notes, updating case files and report writing) the contact. In Glasgow, in that location are typically viii observed contacts and 6 individual interviews over approximately 4 months and the intensity of contacts remains to exist seen in London. Nonetheless, the case may remain open up for some time after the initial contacts, for example, to attend courtroom dates or other judicial meetings. Therefore, whatever farther contacts for each example will be recorded at their xv-calendar month and 2.5-yr follow-ups. The form used in collecting resource use from contacts is provided in online supplementary appendix 2.
Additional service employ
Additional service use (ASU) data will be nerveless with questionnaires at baseline and at each point of follow-up. The ASU questionnaire (see online supplementary appendix iii) aims to obtain an estimate well-nigh the usage of services beyond those provided directly by NIM and CM.
This questionnaire asks birth parents and other primary caregivers about the number of attendances, contacts and hours for several dissimilar services (eg, hospital admissions, police contacts, day care or nursery usage etc) for both the child and themselves. These additional services are important resource utilize items to capture equally CM and NIM both onetime refer patients out to these boosted services, then the ASU provides a method that attempts to capture these.
The ASU Questionnaires will be compared with service utilize at baseline and used in conjunction with information from the NIM and CM services about recommended service uptake to identify what services were used resulting from involvement in either the CM or NIM services.
Valuation of resource use
Unit costs
Unit of measurement costs for each component of resource use will exist expressed in pounds sterling (£) for a base cost year 2020/2021, unit of measurement costs will be obtained from routine sources (ie, NHS Agenda for Change Pay scales, the Personal Social Services Resource Unit, NHS reference costs) or will be collected from the trial directly where they are not available in routine sources. The Hospital and Community Health Services pay and price index21 will exist used to for any inflation.
Outcomes
A number of different outcomes volition be collected by the trial.12 The primary upshot measures of interest for the economic evaluation are the PedsQL14 and the SDQ16 scores, both of which will be used in the economic evaluation.
The PedsQL questionnaire is used to measure HRQoL in children aged 2–xviii. The PedsQL is a validated measure of child quality of life11 22 23 which has recently been mapped to utility values for apply in health economic evaluations.24 The PedsQL has demonstrated responsiveness, construct validity and predictive validity in paediatric patients. The PedsQL scores can exist mapped to generic EQ-5D utilities, facilitating adding of QALYs,xv thus meeting virtually recent Squeamish guidance for public health interventions.25
The SDQ is a short behavioural screening questionnaire that is completed by parents, guardians or teachers of children aged 2–sixteen which records any emotional and behavioural difficulties and whatsoever impairment26 experienced by the kid or family. Children can cocky-complete from ages xi to 17. The SDQ is one of the most widely used validated mensurate of mental wellness in children and is sensitive to alter; in intervention studies, upshot sizes take been shown to be moderate to large.27–29
Tables 1 and 2 provide a summary list of the economical evaluation measures, their schedule collection and the framework for analysis each volition exist used in. As recruitment is rolling, in that location is no set time for baseline, 15-month and 2.v-twelvemonth data drove.

Analysis of cost and effects
Regression analysis will explore the effect that baseline variables have on the cost and outcome (PedsQL and utility) of each intervention over a ii.5-years' time horizon. The incremental divergence in toll and QALYs between groups at follow-up volition be assessed while adjusting for baseline characteristics such equally site, language, gender, baseline PedsQL and impecuniousness. Appropriate methodologies will be used in order to deal with the potential clustering of costs and outcomes past household and intervention site (eg, multilevel models) and with non-normality and correlation of price and outcome information.
Two incremental cost-effectiveness ratio (ICER) volition be calculated to evaluate the incremental price per QALY (calculated from PedsQL scores) and the incremental cost per improvement in SDQ.
The ICER formula is given beneath:
(1)
A CCA will be presented in tabular format with costs collected from the resource used in the trial presented on one side (tabular array 1) and all outcomes listed along the other side (tabular array 2).
Subgroup analysis will explore heterogeneity of the cost-effectiveness results past age group and intervention site.
To reduce bias and increment statistical power, missing information for the key variables used in the Best? trial volition exist imputed separately for each of the ii arms of the trial using multiple imputation by chained equations.xxx–32
Costs and outcomes will be discounted at 1.5% as recommended for public health economic evaluations.18
Treatment doubtfulness
The incertitude surrounding the gauge of incremental costs, QALYs and ICERs will be investigated by use of a non-parametric bootstrap of the toll and outcome pairs for grand iterations.33 This doubtfulness will then be presented on the cost-effectiveness airplane with a 95% CI of the bootstrapped ICER estimated. Results will be summarised using a toll-effectiveness acceptability curve to reverberate the probability of NIM existence cost-constructive at various willingness-to-pay thresholds, including the £xx 000 to £30 000/QALY threshold.24
Heterogeneity will exist explored and subgroup analyses undertaken, for example, based on study site, age groups and other relevant subgroups which may impact on cost-effectiveness . Scenario analyses volition be conducted to examine the effect of the costs and consequences of the services to the firsthand family unit of the child in intendance. To this finish, ICERs volition be recalculated including the costs and effects to the nascence families and other master caregivers (largely the fourth dimension spent past these individuals during the period over which the service was provided).
Long-term population health economic model
While the within-trial economical evaluation assumes a relevant fourth dimension horizon of 2.5 years, modelling the long-term price-effectiveness of the NIM intervention will consider the wide spectrum of cantankerous-sectoral impacts and costs to society of the intervention34 35 over the lifetime.
While several studies accept evaluated interventions aiming at improving children's' mental health in terms of effectiveness36 and cost-effectiveness,37–39 evidence over a lifetime horizon is limited40 41 and not-wellness costs and consequences are rarely considered.9
Still, improvements in child mental health are likely to have broad societal (health and non-health related) and long-lasting impacts on the child, including reducing the hazard of poor physical health, problems with substance abuse, suicide or other mental health risks, involvement in law-breaking.1 ii 29 39 42 43
Furthermore, in line with the theory of 'Investing in Child Health',44 the social rate of return of more resource-consuming interventions directed to improve child mental health is probable to be potentially high, thus justifying the additional costs sustained by the decision-maker.viii 39
The aforementioned multisector lifetime decision model will exist based on the theory of 'Investing in Child Wellness'44 and will be adapted to model the long-term toll and outcomes from NIM and CM in four key sectors in guild: education system, child welfare system, criminal justice, NHS and PSS as informed by this theory.
Online supplementary appendix 4 illustrates the economic logic model adult for this written report which will inform the basic structure of the model.
Pending within-trial results, a Markov model (a mathematical model used to model randomly changing systems where it is assumed that future states depend just on the electric current land not on the events that occurred before it) will be used to predict the multisector lifetime cost-effectiveness.45 Several studies have used this framework to evaluate interventions directed towards the improvement of mental health in both adult46 47 and infant population.38
The economic evaluation of NIM over a long-term horizon will employ the trial data and consequence measures at 15-calendar month and 2.five-year follow-up as predictors for parameter estimates in the lifetime model, and will be further supported by testify from a systematic literature review and available record routine linkage data.
Considering the broad societal impacts and the multidisciplinary nature of many circuitous public wellness interventions affecting mental health, the model will calculate lifetime price and sector-specific outcomes for each of the iv key sectors (social care, informal care, production losses, crime and education),48 for the NIM intervention in comparison to CM including resource use; patient management and pathways; the cantankerous-sectoral affect and implications of early on intervention; quality of life; mortality and adverse events.
Specifically, routine data and a systematic literature review will inform specific parameters that will link early interventions on infant mental health—and related improvements in quality of life—with better health, educational and occupational outcomes, lower criminal offense rates and price savings for the health sector and the entire society.
Sensitivity analysis
Given that the assumptions about causal links from the trial into the future may not be valid over a long time frame (ie, over a child's lifetime), extensive sensitivity analyses will be conducted to explore the effects of adjusting the underlying model parameter estimates and assumptions. Probabilistic sensitivity analysis effectually the longer-term estimates of costs, effects and cost-effectiveness of the NIM intervention versus CM will be performed using a yard iteration Monte Carlo simulation. Further, an alternative discount rate of 3.5% volition be applied to costs and furnishings in line with Overnice guidelines.24 Scenario analyses will explore altering some of the underlying model assumptions.
Discussion
The economic evaluation aslope the All-time? has been prospectively designed to identify, measure out, and value fundamental resource and consequence impacts arising from the NIM compared with CM. This is the first economical evaluation of its kind in the United kingdom of great britain and northern ireland and the improver of a long-term economic model, multiple economical evaluation frameworks and public health economic evaluation methods guidance, should provide determination-makers with a comprehensive guide as to the probable cost-effectiveness of NIM. Given the complexity of the economical evaluation, primal practical steps assisted the blueprint including the development of a health economics logic model and key stakeholder engagement to identify the total range of ASU impacts arising from the intervention.
The All-time? is comparing circuitous interventions within a circuitous social care environment. NIM is a tailored and resources intense intervention with contextual factors influencing the bespoke nature; this will make the findings less generalisable to contexts outside of the UK. Equally, even though CM ensures adherence to standardised procedure, certain cases may be much more resources intense affecting toll-effectiveness.
The planned economic evaluation does have some limiting factors. In that location is potentially a risk of bias due to measurement challenges. Different services delivered in the intervention and in the control arm required different systems to collect resource use information. Furthermore, while the data nerveless within the airplane pilot report have been carried over to the BeST?, the data collection instruments which have been used differ slightly between the pilot and the principal trial. Additionally, the control intervention is not standardised betwixt the Glasgow and the London site. However, nosotros have planned for this and where possible, steps (eg, preliminary checks of the data collected; breezy contacts with professionals in charge of information collection) will be taken to minimise this gamble.
The base of operations instance CUA relies on a utility measure that will not exist directly measured past the children themselves, rather they will exist mapped from the non-preference-based PedsQL to preference-based EQ-5D for adults. While this has its limitations, at the time of trial design (2011), at that place was not a validated paediatric preference-based quality of life measure.
Additionally, the Child Wellness Utility 9D (CHU9D) was validated for employ in children in 2012 for ages 7–1149 which is older than the targeted population of children. The very young children included in the study volition besides pose difficulties in terms of outcome measurement, because many of the paediatric outcomes included in the trial have non been validated for children under the age of two including the PedsQL although by the final trial assessment point, all children will have reached at least age two.v years. Despite these limitations, the recent mapping of the PedsQL to QALY does besides represent a strength of current piece of work, since information technology has allowed the estimation of children-specific health utilities.15 Further, the challenges mentioned above will exist addressed through use of multiple economical evaluation frameworks, giving determination-makers transparent and comprehensive findings with which to improve resources allocation for this vulnerable population.
Given the broader and long-term consequences that inadequate responses to neglected and abused children has for the wellness sector and the order, investing in child health represents a cardinal priority for the decision-maker. In this regard, the current study will provide evidence on the long-term value for money provided by a mental wellness private-based intervention in the Great britain context.

Results of the primary trial and economical evaluation will be submitted for publication in a peer-reviewed periodical too as published in the peer-reviewed National Found for Wellness Research journals library (Public Health Research Program).
