Objectives: To determine the total annual screening and further-investigation costs of investigating false-positive and true-positive mammograms in the Australian population breast-screening program. Methods: This economic analysis used aggregate-level retrospective cohort data of women screened at a breast-screening clinic. Counts and frequencies of each diagnostic workup-sequence recorded were scaled up to national figures and costed by estimating per-patient costs of procedures using screening clinic cost data. Main outcomes and measures estimated were percentage share of total annual screening and further-investigation costs for the Australian population breast-screening program of investigating false-positive and true-positive mammograms. Secondary outcomes determined were average costs of investigating each false-positive and true-positive mammogram. Sensitivity analyses involved recalculating results excluding subgroups of patients below and above the screening age range of 50–74 years. Results: Of 8235 patients, the median age was 60.35 years with interquartile range of 54.17–67.17 years. A total of 15.4% (ranging from 13.4 to 15.4% under different scenarios) of total annual screening and further-investigation costs were from investigating false-positive mammograms. This exceeded the share of costs from investigating true-positives (13%). Conclusions: We have developed a transparent and non-onerous approach for estimating the costs of false-positive and true-positive mammograms associated with the national breast-screening program. While determining an optimal balance between false-positives and true-positive rates must rely primarily on health outcomes, costs are an important consideration. We recommend that future research adopts and refines similar approaches to facilitate better monitoring of these costs, benchmark against estimates from other screening programs, and support optimal policy development. What is known about the topic? Screening mammogram results suggesting cancer later found to be wrong by follow-up testing (false-positive mammograms) consume healthcare resources unnecessarily and increases anxiety among screened women. What does this paper add? This paper estimates the share of total annual costs of Australia's national breast screening program caused by follow up testing of false-positive mammograms at approximately 15%. What are the implications for practitioners? The share of annual breast cancer screening costs from follow-up testing of false-positive mammograms can be monitored over time using the transparent and non-onerous method developed in this paper.

Objective 'Nudges' are subtle cognitive cues thought to influence behaviour. We investigated whether embedding nudges in a general practitioner (GP) clinical decision support display can reduce low-value management decisions. Methods Australian GPs completed four clinical vignettes of patients with low back pain. Participants chose from three guideline-concordant and three guideline-discordant (low-value) management options for each vignette, on a computer screen. A 2x2 factorial design randomised participants to two possible nudge interventions: 'partition display' nudge (low-value options presented horizontally, high-value options listed vertically) or 'default option' nudge (high-value options presented as the default, low-value options presented only after clicking for more). The primary outcome was the proportion of scenarios where practitioners chose at least one of the low-value care options. Results 120 GPs (72% male, 28% female) completed the trial (n=480 vignettes). Participants using a conventional menu display without nudges chose at least one low-value care option in 42% of scenarios. Participants exposed to the default option nudge were 44% less likely to choose at least one low-value care option (OR 0.56, 95% CI 0.37 to 0.85; p=0.006) compared with those not exposed. The partition display nudge had no effect on choice of low-value care (OR 1.08, 95% CI 0.72 to 1.64; p=0.7). There was no interaction between the nudges (OR 0.94, 95% CI 0.41 to 2.15; p=0.89). Interpretation A default option nudge reduced the odds of choosing low-value options for low back pain in clinical vignettes. Embedding high value options as defaults in clinical decision support tools could improve quality of care. More research is needed into how nudges impact clinical decision-making in different contexts. [ABSTRACT FROM AUTHOR]

Introduction Nudge-interventions aimed at health professionals are proposed to reduce the overuse and underuse of health services. However, little is known about their effectiveness at changing health professionals' behaviours in relation to overuse or underuse of tests or treatments. Objective The aim of this study is to systematically identify and synthesise the studies that have assessed the effect of nudge-interventions aimed at health professionals on the overuse or underuse of health services. Methods and analysis We will perform a systematic review. All study designs that include a control comparison will be included. Any qualified health professional, across any specialty or setting, will be included. Only nudgeinterventions aimed at altering the behaviour of health professionals will be included. We will examine the effect of choice architecture nudges (default options, active choice, framing effects, order effects) and social nudges (accountable justification and pre-commitment or publicly declared pledge/contract). Studies with outcomes relevant to overuse or underuse of health services will be included. Relevant studies will be identified by a computer-aided search of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, CINAHL, Embase and PsycINFO databases. Two independent reviewers will screen studies for eligibility, extract data and perform the risk of bias assessment using the criteria recommended by the Cochrane Effective Practice and Organisation of Care (EPOC) group. We will report our results in a structured synthesis format, as recommended by the Cochrane EPOC group. Ethics and dissemination No ethical approval is required for this study. Results will be presented at relevant scientific conferences and in peer-reviewed literature. [ABSTRACT FROM AUTHOR]

The aim of this study is to expound the influences of the five dimensions of hotel hospitality or HotHos as proposed by Ariffin & Maghzi (2012) on guest satisfaction in the context of luxury hotel experiences. This preliminary study involved the participation of 101 hotel guests from Malaysia and overseas and covered the five dimensions of hospitality, which are personalization, warm welcoming, special relationship, straight from the heart and comfort. The findings indicate that out of the five dimensions, only three dimensions, namely personalization, comfort and straight from the heart; predict guest satisfaction in a luxury hotel setting. The findings help luxury hotel managers to better understand how to increase their guest satisfaction within the context of hospitality. [ABSTRACT FROM AUTHOR]

The article surveys the theoretical arguments that explain why privatization can induce changes which promote efficiency and productivity in privatized firms and more generally across the industry in which privatization takes place. It discusses empirical evidence on the effects of privatization in a range of economies. The implications of this body of research are summarized and put in perspective.
