The effect of gender and age on the association between weight status and health-related quality of life in Australian adolescents

Evidence suggests an inverse relationship between excess weight and health-related quality of life (HRQoL) in children and adolescents, however little is known about whether this association is moderated by variables such as gender and age. This study aimed to investigate these relationships.

Suzhi development: Indigenous approaches to enhancing the quality of human resources

Purpose- This paper aims to examine the Chinese indigenous concept of suzhi ((ProQuest: Non US-ASCII text omitted)) by analyzing its historical evolution and its contemporary implications for human resource management (HRM) research and practice at the national and organizational levels.Design/methodology/approach- An integrated review of literatures in sinology, political science, anthropology and sociology concerned with suzhi-related research, combined with recent incidents associated with suzhi.Findings-Suzhi is an indigenous concept embedded in the centuries-long historical context of China.Suzhi development has been focused on three key dimensions, moral, physical and mental, as a way of building quality employees and citizens. Yet developing and quantifying the moral aspects ofsuzhi is more challenging than measuring its physical and mental dimensions. Linkingsuzhi development to human capital theory enriches the understanding of this indigenous concept at both organizational and national levels.Research limitations/implications- By analyzing a three-dimensionalsuzhi composite, the article offers an example of howsuzhi may be linked to human capital theory and identifies directions for future research.Originality/value- By analyzingsuzhi at organizational and national levels for HRM purposes, this article broadens thesuzhi literature from its place in the political sciences and social anthropology to encompass a theoretical analysis in HRM and development for the benefit of organizations and the society.

The National Safety and Quality Health Service Standards requirements for orientation and induction within Australian healthcare: a review of the literature

Introduction: A workplace orientation program is a core requirement of the National Safety and Quality Health Service (NSQHS) Standards in Australia. This is particularly important within healthcare as patient safety and the patient experience are at risk if the healthcare workforce is not supported with an effective orientation and induction program. Aim: This study aimed to review the literature and map the requirements of the NSQHS Standards in relation to orientation and induction. Method: This study utilised online databases to search for literature pertaining to orientation and induction within healthcare. Inclusion criteria included relevance to research questions, and originating in a country with a comparative health system to Australia. Results: The search identified a total of 202 articles of potential relevance with 42 articles meeting the inclusion criteria. Articles were ranked according to hierarchy of evidence criteria for both qualitative and quantitative studies. The importance of using orientation to detail safety and quality roles, the organisations' risk management system, governance structure, operational processes and procedures was highlighted. Patient-centred care, antimicrobial stewardship, clinical handover and mechanisms for escalation of care and emergency assistance should also be covered within the orientation process. Conclusion: There is a dearth of studies in relation to orientation and induction in the healthcare literature. Orientation content is now clearly prescribed, what is lacking within healthcare is a standardised framework. Concept mapping, educational theory and adult learning methods have been shown to enhance workforce problem solving and engagement with orientation, however further research is needed to enhance practice

Self-reported access to and quality of healthcare for diabetes : Do the severely obese experience equal access?

Background: Given reported pejorative views that health professionals have about patients who are severely obese, we examined the self-reported views of the quality and availability of diabetes care from the perspective of adults with type 2 diabetes (T2DM), stratified by body mass index (BMI). Methods: 1795 respondents to the Diabetes MILES - Australia national survey had T2DM. Of these, 530 (30%) were severely obese (BMI ≥35 kg/m2) and these participants were matched with 530 controls (BMI <35 kg/m2). Data regarding participants' self-reported interactions with health practitioners and services were compared. Results: Over 70% of participants reported that their general practitioner was the professional they relied on most for diabetes care. There were no betweengroup differences in patient-reported availability of health services, quality of interaction with health practitioners, resources and support for selfmanagement, or access to almost all diabetes services. Discussion: Participants who were severely obese did not generally report greater difficulty in accessing diabetes care.

Changes in quality of life associated with fragility fractures: Australian arm of the International Cost and Utility Related to Osteoporotic Fractures Study (AusICUROS).

We investigated change in health-related quality of life due to fracture in Australian adults aged over 50 years. Fractures reduce quality of life with the loss sustained at least over 12 months. At a population level, the loss was equivalent to 65 days in full health per fracture.

A new computerized adaptive test advancing the measurement of health-related quality of life (HRQoL) in children: the Kids-CAT

Purpose: Assessing health-related quality of life (HRQoL) via Computerized Adaptive Tests (CAT) provides greater measurement precision coupled with a lower test burden compared to conventional tests. Currently, there are no European pediatric HRQoL CATs available. This manuscript aims at describing the development of a HRQoL CAT for children and adolescents: the Kids-CAT, which was developed based on the established KIDSCREEN-27 HRQoL domain structure. Methods: The Kids-CAT was developed combining classical test theory and item response theory methods and using large archival data of European KIDSCREEN norm studies (n = 10,577–19,580). Methods were applied in line with the US PROMIS project. Item bank development included the investigation of unidimensionality, local independence, exploration of Differential Item Functioning (DIF), evaluation of Item Response Curves (IRCs), estimation and norming of item parameters as well as first CAT simulations. Results: The Kids-CAT was successfully built covering five item banks (with 26–46 items each) to measure physical well-being, psychological well-being, parent relations, social support and peers, and school well-being. The Kids-CAT item banks proved excellent psychometric properties: high content validity, unidimensionality, local independence, low DIF, and model conform IRCs. In CAT simulations, seven items were needed to achieve a measurement precision between.8 and.9 (reliability). It has a child-friendly design, is easy accessible online and gives immediate feedback reports of scores. Conclusions: The Kids-CAT has the potential to advance pediatric HRQoL measurement by making it less burdensome and enhancing the patient–doctor communication.

The ProCaSP study: quality of life outcomes of prostate cancer patients after radiotherapy or radical prostatectomy in a cohort study urological oncology

Background: This study describes and compares health-related quality of life (HRQOL) of prostate cancer patients who received either radical prostatectomy (nerve-sparing, nsRP, or non-nerve-sparing, nnsRP) or radiotherapy (external RT, brachytherapy, or both combined) for treatment of localised prostate cancer. Methods: The prospective, multicenter cohort study included 529 patients. Questionnaires included the IIEF, QLQ-C30, and PORPUS-P. Data were collected before (baseline), three, six, twelve, and twenty-four months after treatment. Differences between groups' baseline characteristics were assessed; changes over time were analysed with generalised estimating equations (GEE). Missing values were treated with multiple imputation. Further, scores at baseline and end of follow-up were compared to German reference data. Results: The typical time trend was a decrease of average HRQOL three months after treatment followed by (partial) recovery. RP patients experienced considerable impairment in sexual functioning. The covariate-adjusted GEE identified a significant - but not clinically relevant - treatment effect for diarrhoea (b∈=∈7.0 for RT, p∈=∈0.006) and PORPUS-P (b∈=∈2.3 for nsRP, b∈=∈2.2 for RT, p∈=∈0.045) compared to the reference nnsRP. Most of the HRQOL scores were comparable to German norm values. Conclusions: Findings from previous research were reproduced in a specific setting of a patient cohort in the German health care system. According to the principle of evidence-based medicine, this strengthens the messages regarding treatment in prostate cancer and its impacts on patients' health-related quality of life. After adjustment for baseline HRQOL and other covariates, RT patients reported increased symptoms of diarrhoea, and nnsRP patients decreased prostate-specific HRQOL. RP patients experienced considerable impairment in sexual functioning. These differences should be taken into account by physicians when choosing the best therapy for a patient.

Improving the quality of prediction intervals through optimal aggregation

Neural networks (NNs) are an effective tool to model nonlinear systems. However, their forecasting performance significantly drops in the presence of process uncertainties and disturbances. NN-based prediction intervals (PIs) offer an alternative solution to appropriately quantify uncertainties and disturbances associated with point forecasts. In this paper, an NN ensemble procedure is proposed to construct quality PIs. A recently developed lower-upper bound estimation method is applied to develop NN-based PIs. Then, constructed PIs from the NN ensemble members are combined using a weighted averaging mechanism. Simulated annealing and a genetic algorithm are used to optimally adjust the weights for the aggregation mechanism. The proposed method is examined for three different case studies. Simulation results reveal that the proposed method improves the average PI quality of individual NNs by 22%, 18%, and 78% for the first, second, and third case studies, respectively. The simulation study also demonstrates that a 3%-4% improvement in the quality of PIs can be achieved using the proposed method compared to the simple averaging aggregation method.

The distribution of quality of life in Australia

 Australians enjoy a relatively high degree of life quality as judged by comparative international statistics. This chapter reviews the distribution of Quality of Life in Australia by considering both the objective and subjective wellbeing (SWB) of the Australian population. The review begins with an overview of objective circumstances, including income, social support, and life expectancy. It also considers the distribution of trust. Two extant measures of the subjective wellbeing of Australians are then reviewed, and it is revealed that SWB has demonstrated remarkably stable properties over the last 12 years. This chapter provides some insight into the properties of the measures and the theoretical construct of Subjective Wellbeing to explain fluctuations that occur for different components of SWB. Further, this chapter considers the demographic characteristics that are common to Australians with higher and lower SWB and offers a basis of research upon which future measures of population wellbeing can be founded
