Evaluation of a universal early intervention for parents and children from birth to age five

Background

This study aimed to investigate the health and economic outcomes of a universal early intervention for parents and children, the Salut Programme, from birth to when the child completed five years of age.

Methods

This study adopted a retrospective observational design using routinely collected register data with respect to both exposures and outcomes from a county in northern Sweden. Areas that received care-as-usual (non-Salut area) were compared to areas where the Programme was implemented after 2006 (Salut area) in terms of: i) health outcomes, healthcare resource use and related costs around pregnancy, delivery and birth, and ii) healthcare resource use and related costs, as well as costs related to care of sick child. Costs were estimated for inpatient care and specialised outpatient care for mothers and children. Two analyses were conducted: a matched difference-in difference analysis using the total sample and an analysis including a longitudinal subsample.

Results

The longitudinal analysis on mothers who had given birth in both the pre- and post-measure periods showed that those that had been exposed to the Salut Programme, had on average 6% (95% CI 3-9%) more full-term pregnancies and 2% (95% CI 0.03-3%) more babies born within normal weight range, compared to mothers who had only care-as-usual. Savings were incurred in terms of outpatient care related costs for children of mothers in the Salut area ($826). The difference-in-difference analysis using the total sample did not result in any significant differences in health outcomes or cumulative resource use over time.

Conclusions

The Salut Programme achieved health gains at a reasonable cost for children and parents, and may lead to lower usage of outpatient care. Other indicators point towards positive effects but the small sample size may have led to underestimation of true differences. The current findings support the continuous investment in this early childhood programme.

Key messages

• The Salut Programme improves the health of children and parents at a low cost.

• The Salut Programme as a health promotion early intervention is value for money and should be included in the local policy investment agenda.

The long-term mental health outcome of adolescent with depression and alcohol abuse comorbidity

Background

Alcohol abuse often co-occurs with adolescent depression and about 1-2% suffer from the dual diagnosis in adolescence. This group is often undertreated or receive inadequate treatment for either of the conditions. Both conditions affect the developing brain and poor long-term outcome might be a potential risk. Yet, long-term follow-up studies are scarce. The aim of this study was to analyse if adolescent depression and alcohol abuse predict poorer mental health in adulthood compared to individuals without either or both conditions.

Methods

A community-based sample of individuals with adolescent depression in 1991-93 and matched non-depressed peers were followed up using a structured diagnostic interview after 15 years. The participation rate was 65% (depressed n = 227; non-depressed controls n = 155). Information on alcohol abuse in adolescence was collected at baseline with a structured interview. The outcome was mental disorders between the ages 19-31 years; information on depression and alcohol abuse was collected at the follow-up with a structured diagnostic interview. The statistical method used was binary logistic regression.

Results

Adolescents with depression and alcohol abuse had an excess risk of recurrence of depression (OR 2.12, p < 0.05) and alcohol abuse (OR 6.72, p < 0.01) in adulthood, compared with adolescents with depression only, even when adjusted for confounders. Adolescents with alcohol abuse only had not significantly worse long-term outcome compared with their healthy peers.

Conclusions

The co-occurrence of depression and alcohol abuse in adolescence is associated with long-lasting health consequences compared to either condition alone. This finding indicates that there is a need to prioritize this group of patients that is at risk of suboptimal treatment, and to further develop effective treatment adjusted to the co-occurring condition.

Key messages

The co-occurrence of adolescent depression and alcohol abuse has long lasting mental health consequences compared to either condition alone. Improved treatment methods are important for this group of adolescents.

Economic evaluations of public health interventions for physical activity and diet: systematic review

Background

Physical inactivity and unhealthy dietary habits are associated with an increased disease and economic burden. Despite the prevalence of different public health programs, decision-makers encounter a multitude of challenges in prioritizing interventions for optimal resource allocation. The aim of this systematic review, therefore, was to identify economic evaluations of public health interventions targeting physical activity and healthy diet, and assess the quality and transferability of the findings to the Swedish context.

Methods

A search of published economic evaluations was conducted through electronic databases including PubMed, Web of Science, PsycINFO, National Health Service Economic Evaluation Databases (NHS EED) and the Health Technology Assessment Database (HTA). An additional search was done using references of relevant systematic reviews and, websites of relevant organizations were checked to find grey literature. Quality and transferability of the economic evaluations were appraised using a quality assessment tool developed by the Swedish Agency for Health Technology Assessment.

Preliminary Results

Thirty-two economic evaluations of 178 interventions were included; thirteen studies targeting physical activity, thirteen targeting healthy diet and six targeting both. The interventions varied in terms of their content, setting, mode of delivery and target populations. A majority of the economic evaluations reported that the interventions were likely to be cost-effective; however, considerable variations in the methodological and reporting qualities were observed. Only half of the economic evaluations were rated to have a high probability of transferring to the Swedish context.

Conclusions

Most of the interventions were reported to be cost-effective. However, a variation in quality and transferability of the available evidence to the Swedish context were observed.

Key messages

Public health interventions targeting physical activity and dietary habits have a high potential to be cost-effective. Decision makers should consider transferability and suitability of findings of economic evaluation from a different context to a decision problem at hand.

Economic evaluations of public health interventions for mental health: A systematic literature review

Background

To review the literature on economic evaluations of public health interventions targeting prevention of mental health problems and suicide, to support evidence based societal resource allocation.

Methods

A systematic review of economic evaluations within mental health and suicide prevention was conducted including studies published between 2000 and 2018. The studies were identified through Medline, PsychINFO, Web of Science. The quality of relevant studies and the transferability of their results were assessed using a criterion set out by the Swedish Agency for Health Technology Assessment.

Results

Nineteen studies of moderate to high quality were included in this review, which evaluated 18 interventions in mental health and 4 interventions in suicide prevention. Fourteen (63%) of all interventions were cost-effective. None of the studies that evaluated suicide prevention was of high quality. The interventions largely focused on psychological interventions at school, the workplace and within elderly care as well as screening and brief interventions in primary care. Nine studies (around 50% of included articles) had a high potential for transferability to the Swedish context.

Conclusions

Public health interventions aiming to improve mental health have a high potential to be economically beneficial to society, but high-quality evidence on the cost-effectiveness of suicide prevention is limited.

Key messages

Public health interventions aiming to improve mental health have a high potential to be economically beneficial to society. Evidence on the cost-effectiveness of suicide prevention is limited.

Cost-effectiveness of an indicated preventive intervention for depression in adolescents

Background

Adolescent depression has negative health and economic outcomes in the short- and long-term. Indicated preventive interventions, in particular group based cognitive behavioural therapy (GB-CBT), are effective in preventing depression in adolescents with subsyndromal depression. However, little is known about the cost-effectiveness of these interventions.

Methods

A Markov cohort model was used to conduct cost-effectiveness analyses comparing a GB-CBT indicated preventive intervention for depression, to a no-intervention option. Taking a time horizon of 5- and 10 years, incremental differences in societal costs and health benefits expressed as cases of depression prevented, and as quality adjusted life years (QALYs) gained were estimated. Through univariate and probabilistic sensitivity analyses, the robustness of the results was explored. Costs, presented in 2018 USD, and effects were discounted at a yearly rate of 3%.

Results

The base-case analysis showed that GB-CBT indicated preventive intervention incurred lower costs, prevented more cases of depression and generated higher QALYs compared to the no-intervention option for both time horizons. Offering the intervention was even a cost saving strategy and demonstrated a probability of being cost-effective of over 95%. In the sensitivity analyses, these results were robust to the modelling assumptions. Limitations: The study considered a homogeneous cohort and assumed a constant annual decay rate of the relative treatment effect.

Conclusions

GB-CBT indicated preventive interventions for depression in adolescence can generate good value for money compared to leaving adolescents with subsyndromal depression untreated.

Key messages

Indicated preventive interventions for depression are cost-saving and can generate substantial health benefits. Indicated preventive interventions can be adopted as cost-effective preventive strategies for depression.
