RESUMO

BACKGROUND: Digital Mental Health Interventions (DMHIs) that meet the definition of a medical device are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. The MHRA uses procedures that were originally developed for pharmaceuticals to assess the safety of DMHIs. There is recognition that this may not be ideal, as is evident by an ongoing consultation for reform led by the MHRA and the National Institute for Health and Care Excellence. AIMS: The aim of this study was to generate an experts' consensus on how the medical regulatory method used for assessing safety could best be adapted for DMHIs. METHOD: An online Delphi study containing three rounds was conducted with an international panel of 20 experts with experience/knowledge in the field of UK digital mental health. RESULTS: Sixty-four items were generated, of which 41 achieved consensus (64%). Consensus emerged around ten recommendations, falling into five main themes: Enhancing the quality of adverse events data in DMHIs; Re-defining serious adverse events for DMHIs; Reassessing short-term symptom deterioration in psychological interventions as a therapeutic risk; Maximising the benefit of the Yellow Card Scheme; and Developing a harmonised approach for assessing the safety of psychological interventions in general. CONCLUSION: The implementation of the recommendations provided by this consensus could improve the assessment of safety of DMHIs, making them more effective in detecting and mitigating risk.

RESUMO

BACKGROUND: Persecutory delusions are strong threat beliefs about others' negative intentions. They can have a major impact on patients' day-to-day life. The Feeling Safe Programme is a new translational cognitive-behaviour therapy that helps patients modify threat beliefs and relearn safety by targeting key psychological causal factors. A different intervention approach, with growing international interest, is peer counselling to facilitate personal recovery. Combining these two approaches is a potential avenue to maximize patient outcomes. This combination of two different treatments will be tested as the Feeling Safe-NL Programme, which aims to promote psychological wellbeing. We will test whether Feeling Safe-NL is more effective and more cost-effective in improving mental wellbeing and reducing persecutory delusions than the current guideline intervention of formulation-based CBT for psychosis (CBTp). METHODS: A single-blind parallel-group randomized controlled trial for 190 out-patients who experience persecutory delusions and low mental wellbeing. Patients will be randomized (1:1) to Feeling Safe-NL (Feeling Safe and peer counselling) or to formulation-based CBTp, both provided over a period of 6 months. Participants in both conditions are offered the possibility to self-monitor their recovery process. Blinded assessments will be conducted at 0, 6 (post-treatment), 12, and 18 months. The primary outcome is mental wellbeing. The overall effect over time (baseline to 18-month follow-up) and the effects at each timepoint will be determined. Secondary outcomes include the severity of the persecutory delusion, general paranoid ideation, patient-chosen therapy outcomes, and activity. Service use data and quality of life data will be collected for the health-economic evaluation. DISCUSSION: The Feeling Safe-NL Trial is the first to evaluate a treatment for people with persecutory delusions, while using mental wellbeing as the primary outcome. It will also provide the first evaluation of the combination of a peer counselling intervention and a CBT-based program for recovery from persecutory delusions. TRIAL REGISTRATION: Current Controlled Trials ISRCTN25766661 (retrospectively registered 7 July 2022).

RESUMO

AIM: Traumatic events are involved in the development and maintenance of psychotic symptoms. There are few trials exploring trauma-focused treatments as interventions for psychotic symptoms, especially in individuals with early psychosis. This trial will evaluate the feasibility and acceptability of conducting a definitive trial of Eye Movement Desensitization and Reprocessing for psychosis (EMDRp) in people with early psychosis. METHODS: Sixty participants with first episode psychosis and a history of a traumatic/adverse life event(s)will be recruited from early intervention services in the North West of England and randomized to receive16 sessions of EMDRp + Treatment as Usual (TAU) or TAU alone. Participants will be assessed at baseline, 6 and 12 months post-randomization using several measures of psychotic symptoms, trauma symptoms, anxiety, depression, functioning, service-user defined recovery, health economics indicators and quality of life. Two nested qualitative studies to assess participant feedback of therapy and views of professional stakeholders on the implementation of EMDRp into services will also be conducted. The feasibility of a future definitive efficacy and cost-effectiveness evaluation of EMDRp will be tested against several outcomes, including ability to recruit and randomize participants, trial retention at 6- and 12-month follow-up assessments, treatment engagement and treatment fidelity. CONCLUSIONS: If it is feasible to deliver a multi-site trial of this intervention, it will be possible to evaluate whether EMDRp represents a beneficial treatment to augment existing evidence-based care of individuals with early psychosis supported by early intervention services.

RESUMO

Background: Co-occurrence of posttraumatic stress disorder (PTSD) in psychosis (estimated as 12%) raises personal suffering and societal costs. Health-economic studies on PTSD treatments in patients with a diagnosis of a psychotic disorder have not yet been conducted, but are needed for guideline development and implementation. This study aims to analyse the cost-effectiveness of guideline PTSD therapies in patients with a psychotic disorder. Methods: This health-economic evaluation alongside a randomized controlled trial included 155 patients with a psychotic disorder in care as usual (CAU), with comorbid PTSD. Participants received eye movement desensitization and reprocessing (EMDR) (n = 55), prolonged exposure (PE) (n = 53) or waiting list (WL) (n = 47) with masked assessments at baseline (T0) and at the two-month (post-treatment, T2) and six-month follow-up (T6). Costs were calculated using the TiC-P interview for assessing healthcare consumption and productivity losses. Incremental cost-effectiveness ratios and economic acceptability were calculated for quality-adjusted life years (EQ-5D-3L-based QALYs) and PTSD 'Loss of diagnosis' (LoD, CAPS). Results: Compared to WL, costs were lower in EMDR (-€1410) and PE (-€501) per patient per six months. In addition, EMDR (robust SE 0.024, t = 2.14, p = .035) and PE (robust SE 0.024, t = 2.14, p = .035) yielded a 0.052 and 0.051 incremental QALY gain, respectively, as well as 26% greater probability for LoD following EMDR (robust SE = 0.096, z = 2.66, p = .008) and 22% following PE (robust SE 0.098, z = 2.28, p = .023). Acceptability curves indicate high probabilities of PTSD treatments being the better economic choice. Sensitivity analyses corroborated these outcomes. Conclusion: Adding PTSD treatment to CAU for individuals with psychosis and PTSD seem to yield better health and less PTSD at lower costs, which argues for implementation.


Antecedentes: La comorbilidad de TEPT en la psicosis (estimada en 12%) aumenta el sufrimiento personal y los costos para la sociedad. No se han realizado aún estudios de economía de la salud de los tratamientos de TEPT en pacientes con diagnóstico de un trastorno psicótico, pero son necesarios para el desarrollo e implementación de guías. Este estudio apunta a analizar la costo-efectividad de las terapias para TEPT con guías clínicas en pacientes con un trastorno psicótico.Métodos: Esta evaluación de economía de la salud asociada a un estudio randomizado controlado incluyó a 155 pacientes con un trastorno psicótico en cuidado habitual (CAU), con TEPT comórbido.Los pacientes recibieron terapia de reprocesamiento por movimientos oculares (EMDR, n=55), exposición prolongada (PE, n=53) o lista de espera (WL, n=47) con evaluaciones ciegas basal (T0), a los 2 meses (post-tratamiento, T2) y a los 6 meses de seguimiento (T6). Los costos fueron calculados usando la entrevista TiC-P para evaluar el consumo en los sistemas de salud y pérdidas de productividad. Las tasas incrementales de costo-efectividad y acepabilidad económica fueron calculadas por Años de Vida ajustados por calidad (QALY basado en EQ-5D-3L) y pérdida de diagnóstico de TEPT (LoD, CAPS)Resultados: En comparación a lista de espera, los costos fueron menores en EMDR (-€1410) y PE (-€501) por paciente por cada 6 meses. Además, EMDR (SE robusta 0.024, t=2.14, p=0.035) y PE (SE robusta 0.024, t=2.14, p=0.035) produjeron una ganancia incremental en QALY de 0.05 y una probabilidad 26% mayor de LoD luego de EMDR (SE robusta 0.096, z=2.66, p=0.008) y 22% luego de PE (SE robusta 0.098, z=2.28, p=0.023). Las curvas de aceptabilidad indican altas probabilidades de que los tratamientos para TEPT sean la mejor alternativa económica. Los análisis de sensibilidad corroboraron estos resultados.Conclusion: El agregar tratamiento para TEPT a los cuidados habituales en pacientes con psicosis y TEPT parece producir mejor salud y menos TEPT a menor costo, lo que aboga por su implementación.

RESUMO

The field of digital mental health is rapidly expanding with digital tools being used in assessment, intervention, and supporting self-help. The application of digital mental health to hallucinations is, however, at a very early stage. This report from a working group of the International Consortium on Hallucinations Research considers particular synergies between the phenomenon of hallucinations and digital tools that are being developed. Highlighted uses include monitoring and managing intermittently occurring hallucinations in daily life; therapeutic applications of audio and video media including virtual and augmented reality; targeting verbal aspects of hallucinations; and using avatars to represent hallucinatory voices. Although there is a well-established Internet-based peer support network, digital resources for hallucinations have yet to be implemented in routine practice. Implementation may benefit from identifying how to market resources to the broad range of populations who experience hallucinations and identifying sustainable funding models. It is envisaged that digital tools will contribute to improved self-management and service provision for people experiencing hallucinations.

RESUMO

Background: This study aims to evaluate the long-term cost-effectiveness of add-on cognitive behavior therapy (CBT) for the prevention of psychosis for individuals at ultrahigh risk (UHR) of psychosis. Method: The Dutch Early Detection and Intervention randomized controlled trial was used, comparing routine care (RC; n = 101) with routine care plus CBT for UHR (here called CBTuhr; n = 95). A cost-effectiveness analysis was conducted with treatment response (defined as proportion of averted transitions to psychosis) as an outcome and a cost-utility analysis with quality-adjusted life years (QALYs) gained as a secondary outcome. Results: The proportion of averted transitions to psychosis was significantly higher in the CBTuhr condition (with a risk difference of 0.122; b = 1.324, SEb = 0.017, z = 7.99, P < 0.001). CBTuhr showed an 83% probability of being more effective and less costly than RC by -US$ 5777 (savings) per participant. In addition, over the 4-year follow-up period, cumulative QALY health gains were marginally (but not significantly) higher in CBTuhr than for RC (2.63 vs. 2.46) and the CBTuhr intervention had a 75% probability of being the superior treatment (more QALY gains at lower costs) and a 92% probability of being cost-effective compared with RC at the Dutch threshold value (US$ 24 560; €20 000 per QALY). Conclusions: Add-on preventive CBTuhr had a high likelihood (83%) of resulting in more averted transitions to psychosis and lower costs as compared with RC. In addition, the intervention had a high likelihood (75%) of resulting in more QALY gains and lower costs as compared to RC.

RESUMO

Childhood adversity is associated with a range of mental disorders, functional impairment and higher health care costs in adulthood. In this study we evaluated if childhood adversity was predictive of adverse clinical and functional outcomes and health care costs in a sample of patients at ultra-high risk (UHR) for developing a psychosis. Structural Equation Modeling was used to examine the effect of childhood adversity on depression, anxiety, transition to psychosis and overall functioning at 4-year follow-up. In addition, we evaluated economic costs of childhood adversity in terms of health care use and productivity loss. Data pertain to 105 UHR participants of the Dutch Early Detection and Intervention Evaluation (EDIE-NL). Physical abuse was associated with higher depression rates (b=0.381, p=0.012) and lower social functional outcome (b=-0.219, p=0.017) at 4-year follow-up. In addition, emotional neglect was negatively associated with social functioning (b=-0.313, p=0.018). We did not find evidence that childhood adversity was associated with transition to psychosis, but the experience of childhood adversity was associated with excess health care costs at follow-up. The data indicate long-term negative effects of childhood adversity on depression, social functioning and health care costs at follow-up in a sample of UHR patients.

RESUMO

BACKGROUND: Many epithelial ovarian cancer (EOC) risk factors relate to hormone exposure and elevated estrogen levels are associated with obesity in postmenopausal women. Therefore, we hypothesized that gene-environment interactions related to hormone-related risk factors could differ between obese and non-obese women. METHODS: We considered interactions between 11,441 SNPs within 80 candidate genes related to hormone biosynthesis and metabolism and insulin-like growth factors with six hormone-related factors (oral contraceptive use, parity, endometriosis, tubal ligation, hormone replacement therapy, and estrogen use) and assessed whether these interactions differed between obese and non-obese women. Interactions were assessed using logistic regression models and data from 14 case-control studies (6,247 cases; 10,379 controls). Histotype-specific analyses were also completed. RESULTS: SNPs in the following candidate genes showed notable interaction: IGF1R (rs41497346, estrogen plus progesterone hormone therapy, histology = all, P = 4.9 × 10(-6)) and ESR1 (rs12661437, endometriosis, histology = all, P = 1.5 × 10(-5)). The most notable obesity-gene-hormone risk factor interaction was within INSR (rs113759408, parity, histology = endometrioid, P = 8.8 × 10(-6)). CONCLUSIONS: We have demonstrated the feasibility of assessing multifactor interactions in large genetic epidemiology studies. Follow-up studies are necessary to assess the robustness of our findings for ESR1, CYP11A1, IGF1R, CYP11B1, INSR, and IGFBP2 Future work is needed to develop powerful statistical methods able to detect these complex interactions. IMPACT: Assessment of multifactor interaction is feasible, and, here, suggests that the relationship between genetic variants within candidate genes and hormone-related risk factors may vary EOC susceptibility.

RESUMO

In all, 80% of antenatal karyotypes are generated by Down's syndrome screening programmes (DSSP). After a positive screening, women are offered prenatal foetus karyotyping, the gold standard. Reliable molecular methods for rapid aneuploidy diagnosis (RAD: fluorescence in situ hybridization (FISH) and quantitative fluorescence PCR (QF-PCR)) can detect common aneuploidies, and are faster and less expensive than karyotyping.In the UK, RAD is recommended as a standalone approach in DSSP, whereas the US guidelines recommend that RAD be followed up by karyotyping. A cost-effectiveness (CE) analysis of RAD in various DSSP is lacking. There is a debate over the significance of chromosome abnormalities (CA) detected with karyotyping but not using RAD. Our objectives were to compare the CE of RAD versus karyotyping, to evaluate the clinically significant missed CA and to determine the impact of detecting the missed CA. We performed computer simulations to compare six screening options followed by FISH, PCR or karyotyping using a population of 110948 pregnancies. Among the safer screening strategies, the most cost-effective strategy was contingent screening with QF-PCR (CE ratio of $24084 per Down's syndrome (DS) detected). Using karyotyping, the CE ratio increased to $27898. QF-PCR missed only six clinically significant CA of which only one was expected to confer a high risk of an abnormal outcome. The incremental CE ratio (ICER) to find the CA missed by RAD was $66608 per CA. These costs are much higher than those involved for detecting DS cases. As the DSSP are mainly designed for DS detection, it may be relevant to question the additional costs of karyotyping.

RESUMO

CYP11A catalyzes the rate-limiting step in the biosynthesis of sex-steroid hormones. In this study, we employed a systematic approach that involved gene resequencing and a haplotype-based analysis to investigate the relationship between common variation in CYP11A and breast cancer risk among African-Americans, Latinas, Japanese-Americans, Native Hawaiians, and Whites in the Multiethnic Cohort Study. Resequencing in a multiethnic panel of 95 advanced breast cancer cases revealed no common missense variant (> or =5% frequency). Common haplotype patterns were assessed by genotyping 36 densely spaced single nucleotide polymorphisms (SNPs) spanning 67 kb of the CYP11A locus in a multiethnic panel of subjects (n = 349; 1 SNP/1.86 kb on average). We identified one to two regions of strong linkage disequilibrium in these populations. Twelve tagging SNPs were selected to predict the common haplotypes (> or =5% frequency) in these regions with high probability (average R(h)(2) = 0.94) and were examined in a breast cancer case-control study in the Multiethnic Cohort Study (1,615 cases and 1,962 controls). A global test for differences in risk according to common haplotypes over the locus was statistically significant (P = 0.006), as were associations with haplotypes in each block (block 1 global test, P = 0.008; haplotype 1D, effect per haplotype copy, odds ratios, 1.23; 95% confidence interval, 1.03-1.48) and block 2 (global test, P = 0.016; haplotype 2F odds ratios, 1.52; 95% confidence interval, 1.15-2.01). These haplotypes were most common in Japanese-Americans and Native Hawaiians, followed by Whites then Latinas, and were rare in African-Americans (<5% frequency); the haplotype effects on risk across each group were homogeneous. Based on these findings, CYP11A deserves further consideration as a candidate breast cancer susceptibility gene.
