Societal costs of subclinical depressive symptoms in Dutch adolescents: a cost-of-illness study.

ABSTRACT:

Background

Subclinical depressive symptoms are highly prevalent among adolescents and are associated with negative consequences, which may pose an economic burden for society. We conducted a prevalence-based cost-of-illness study using a societal perspective to investigate the cost-of-illness of subclinical depressive symptoms among adolescents.

Methods

Using a bottom-up approach, cost questionnaires were assessed to measure costs from 237 Dutch families with an adolescent aged 11-18 with subclinical depressive symptoms (of which 34 met the criteria of a depressive disorder). The study is registered in the Dutch Trial Register (Trial NL5584/NTR6176; www.trialregister.nl/trial/5584).

Results

Our calculations show that adolescents with subclinical depressive symptoms cost the Dutch society more than €42 million annually, expressed in costs related to depressive symptoms. Secondary analyses were performed to test the reliability and stability of the costs. When costs related to psychological problems were considered, the annual costs amounted to €67 million. The total societal costs related to physical problems amounted to approximately €126 million. All costs combined (depressive, psychological, behavioural and physical problems and other reasons) amounted to a €243 million. Total costs were highest for physical-related problems of the adolescent (52% of the total costs), followed by psychological (28%), depressive (17%) and behavioural problems (1%). Using an international prevalence rate, societal costs related to depressive symptoms resulted in €54 million a year.

Conclusions

Cost-effective prevention programmes seem warranted given the high societal costs and risk of future costs as subclinical depressive symptoms could be a precursor of clinical depression later in life.

Project description:AimTo estimate annual societal costs associated with chemotherapy for early breast cancer in the UK.DesignMixed methods: (a) an incidence-based cost-of-illness model was developed of indirect costs in patients with breast cancer and carers, and estimated from diagnosis through active treatment until death; (b) interviews with stakeholders were also undertaken to understand actual experiences and impacts of these costs.Data sourcesModel data were collated from relevant national data sources covering general population statistics, UK cancer registries, clinical guidelines and published literature, and patient survey data. Patient and staff views were collected through semistructured interviews.ParticipantsModel: patients with early breast cancer receiving systemic anticancer therapy in the UK. Interviews were undertaken with women who had chemotherapy and medical practitioners involved in breast cancer care.ResultsTotal costs of chemotherapy in the UK economy are over £248 million. Societal productivity losses amount to £141.4 million, which includes £3.2 million associated with premature mortality, short-term and long-term work absence (£28.6 million and £105 million, respectively). £3.4 million is associated with mortality losses from secondary malignancies due to adjuvant chemotherapy. A further £1.1 million in lost productivity arises from informal care provision. Out-of-pocket costs per round of chemotherapy account for £4.2 million, or an annual average of almost £1100 per patient. Interview findings support the cost burden modelled and also highlight the impact on cognitive function of patients and how this could increase the cost burden to patients, their families and wider society. In addition, estimated costs for carer emotional well-being are £82 million in lost quality of life.ConclusionChemotherapy use carries significant indirect costs for society, as well as patients and their carers. These wider costs and societal perspective should be considered by commissioners to ensure chemotherapy is better targeted at those who most need it and to avoid placing unnecessary costs on patients, their caregivers and wider society.

Project description:ObjectiveTo assess whether the relationship between hearing and depressive symptoms is present among older adults classified as normal hearing (≤25 dB).DesignCross-sectional epidemiologic study (Hispanic Community Health Study).SettingUS multicentered.ParticipantsAdults ≥50 years old (n = 5,499) with normal hearing or hearing loss (HL).MeasurementsThe primary exposure was hearing, defined continuously by the 4-frequency pure-tone average threshold (dB) on audiometry. Hearing was additionally categorized into normal hearing (≤25 dB) and HL (>25 dB). The main outcome was depressive symptoms, measured with the Center for Epidemiologic Studies Depression Scale-10 (CESD-10). Depressive symptoms were defined both continuously and binarily (where CESD-10 ≥10 was categorized as clinically significant depressive symptoms). Multivariable linear, logistic, and generalized additive modeling (GAM) regressions were performed.ResultsAmong those with normal hearing, the CESD-10 score increased by 1.04 points (95% confidence interval [CI]: 0.70, 1.37) for every 10 dB decrease in hearing, adjusting for age, gender, education, cardiovascular disease, and hearing aid use. Among those with HL, the CESD-10 score increased by 0.62 points (95% CI: 0.23, 1.01) for every 10 dB decrease in hearing, adjusting for the same confounders. Similar findings were noted when the outcome was clinically significant depressive symptoms (adjusted odds ratio: 1.28 [1.14, 1.44] in normal hearing versus 1.26 [1.11, 1.44] in HL). In certain sensitivity analyses, the relationship between hearing and depressive symptoms was significantly stronger among those with normal hearing than in those with HL.ConclusionThe relationship between hearing and clinically significant depressive symptoms is present among older adults with normal hearing (<25 dB). We introduce the term subclinical HL as imperfect hearing that is classically defined as normal (1-25 dB). The relationship between hearing and late life depressive symptoms may be more sensitive than previously recognized.

Project description:ObjectiveTo estimate the effect of antenatal treatment of subclinical hypothyroidism on maternal depressive symptoms.MethodsWe conducted an ancillary study to a multicenter trial in women with singleton pregnancies diagnosed with subclinical hypothyroidism randomized to antenatal thyroxine therapy or placebo. Treatment was discontinued at the end of pregnancy. Women with overt thyroid disease, diabetes, autoimmune disease, and those diagnosed with depression were excluded. Participants were assessed for depressive symptoms using the Center for Epidemiological Studies-Depression scale (CES-D) before starting the study drug (between 11 and 20 weeks of gestation), between 32 and 38 weeks of gestation, and at 1 year postpartum. The primary outcome was maternal depressive symptoms score as assessed using the CES-D. Secondary outcome was the percentage of women who scored 16 or higher on the CES-D, as such a score is considered screen-positive for depression.ResultsTwo hundred forty-five (36.2% of parent trial) women with subclinical hypothyroidism were allocated to thyroxine (n=124) or placebo (n=121). Median CES-D scores and the proportion of participants with positive scores were similar at baseline between the two groups. Treatment with thyroxine was not associated with differences in CES-D scores (10 [5-15] vs 10 [5-17]; P=.46) or in odds of screening positive in the third trimester compared with placebo, even after adjusting for baseline scores (24.3% vs 30.1%, adjusted odds ratio 0.63, 95% CI 0.31-1.28, P=.20). At 1 year postpartum, CES-D scores were not different (6 [3-11] vs 6 [3-12]; P=.79), nor was the frequency of screen-positive CES-D scores in the treated compared with the placebo group (9.7% vs 15.8%; P=.19). Treatment with thyroxine during pregnancy was also not associated with differences in odds of screening positive at the postpartum visit compared with placebo even after adjusting for baseline scores. Sensitivity analysis including women who were diagnosed with depression by the postpartum visit did not change the results.ConclusionsThis study did not achieve its planned sample size, thus our conclusions may be limited, but in this cohort of pregnant women with subclinical hypothyroidism, antenatal thyroxine replacement did not improve maternal depressive symptoms.
