Cohabitation in Great Britain: not for long, but here to stay

This paper uses a new source of data to study the dramatic increase in cohabiting unions in Great Britain. It analyses, in turn, entry into first partnership, the stability of cohabiting unions and repartnering after dissolution of cohabitation. In excess of 70% of first partnerships are now cohabitations, and these last a relatively short time before being either turned into marriage or dissolved. The shift to cohabitation as the dominant mode of first partnership plays an important role in the delay of first marriage and motherhood. The paper also investigates the factors that are associated with the outcome of cohabitations.     

From Hospital to Home with NDIS Funded Support: Examining Participant Pathway Timeframes Against Discharge Expectations

ABSTRACT

For patients with disability who require funded supports to leave hospital, the introduction of the National Disability Insurance Scheme (NDIS) represents opportunity and challenges. At a time of major reform, timely and supported discharge is reliant on overcoming interface complexities. The purpose of this study was to examine the NDIS participant pathway timeframes against discharge expectations for hospitalised adults with spinal cord injury (SCI) or acquired brain injury (ABI) and interrogate delays for the two groups. Administrative data on 54 participants (ABI?=?18 and SCI?=?36) were analysed. Both groups experienced delays to discharge and significant variability in timeframes between NDIS pathway processes and extent of delays. Group differences were identified regarding inefficiencies across the continuum, with type of support a factor to investigate further. This study has uncovered critical points in the NDIS pathway that could impact discharge of participants and where collaboration and adaptive strategies could be targeted to improve processes.

IMPLICATIONS

• Ensuring the National Disability Insurance Scheme (NDIS) pathway operates effectively in the hospital setting is critical to the timely discharge of people with complex needs who require funded supports.

• Monitoring implementation of the NDIS in the health setting is important to avert interface problems that impede timely discharge and access.

     

Importance sampling type estimators based on approximate marginal Markov chain Monte Carlo

We consider importance sampling (IS) type weighted estimators based on Markov chain Monte Carlo (MCMC) targeting an approximate marginal of the target distribution. In the context of Bayesian latent variable models, the MCMC typically operates on the hyperparameters, and the subsequent weighting may be based on IS or sequential Monte Carlo (SMC), but allows for multilevel techniques as well. The IS approach provides a natural alternative to delayed acceptance (DA) pseudo-marginal/particle MCMC, and has many advantages over DA, including a straightforward parallelization and additional flexibility in MCMC implementation. We detail minimal conditions which ensure strong consistency of the suggested estimators, and provide central limit theorems with expressions for asymptotic variances. We demonstrate how our method can make use of SMC in the state space models context, using Laplace approximations and time-discretized diffusions. Our experimental results are promising and show that the IS-type approach can provide substantial gains relative to an analogous DA scheme, and is often competitive even without parallelization.

Discharge Planning Process on a General Psychiatry Unit

Abstract

This study investigates the discharge-planning process and short-term outcomes for 100 patients discharged from a general psychiatry unit. The contributions of functional/illness factors, personal factors, and family factors to communication of the plan, length of stay, and satisfaction with discharge-planning process were investigated. Findings indicate that both the process and short-term outcomes of discharge planning are affected by factors that can be addressed in interventions with patients, families and the social environment. This research suggests that discharge planning without attention to psychosocial factors will fail to address issues relevant to patient well-being.     

Response-adaptive randomization for survival trials: the parametric approach

Summary.  Few references deal with response-adaptive randomization procedures for survival outcomes and those that do either dichotomize the outcomes or use a non-parametric approach. In this paper, the optimal allocation approach and a parametric response-adaptive randomization procedure are used under exponential and Weibull distributions. The optimal allocation proportions are derived for both distributions and the doubly adaptive biased coin design is applied to target the optimal allocations. The asymptotic variance of the procedure is obtained for the exponential distribution. The effect of intrinsic delay of survival outcomes is treated. These findings are based on rigorous theory but are also verified by simulation. It is shown that using a doubly adaptive biased coin design to target the optimal allocation proportion results in more patients being randomized to the better performing treatment without loss of power. We illustrate our procedure by redesigning a clinical trial.     

Lotus birth,a holistic approach on physiological cord clamping

Background

The positive effects of delayed cord clamping (DCC) has been extensively researched. DCC means: waiting at least one minute after birth before clamping and cutting the cord or till the pulsation has stopped. With physiological clamping and cutting (PCC) the clamping and cutting can happen at the earliest after the pulsation has stopped. With a Lotus birth, no clamping and cutting of the cord is done. A woman called Clair Lotus Day imitated the holistic approach of PCC from an anthropoid ape in 1974. The chimpanzee did not separate the placenta from the newborn.

How does discharge status impact suicide risk in military veterans?

Little is known about over 125,000 veterans who received non-honorable military discharges since 2001, even though these veterans face substantial barriers to obtaining services and are likely to be at high risk for negative mental and behavioral health outcomes including suicide. Seven-hundred twenty-two veterans living the in the San Francisco Bay Area participated in the study. The sample comprised honorably discharged (n = 508) and non-honorably discharged veterans (n = 214). T-tests were used to compare means on predictors of suicide risk including Posttraumatic Stress Disorder (PTSD), depression, alcohol use, somatic symptoms, and physical disability. A series of regression models tested relationships between predictors, discharge status, and suicide risk. Non-honorably discharged veterans demonstrated higher mean scores than honorably discharged veterans on all predictors. In regression models, somatic symptoms (β = 0.22, p < 0.001), physical disability (β = 0.16, p < 0.05), and discharge status (β = 0.33, p < 0.001) were associated with suicide risk. The final model showed an interaction effect for discharge status on the relationship between somatic symptoms and suicide risk (β = 0.16, p < 0.05). Non-honorably discharged veterans showed higher rates of mental and physical health problems and suicide risk compared to honorably discharged veterans. The magnitude of the relationship between somatic symptoms and suicide risk was significantly greater in non-honorably discharged veterans.
