Safety Netting

BackgroundChildren’s use of urgent care services continues to increase. If families are to access the right services at the right time they need access to information to inform their decision making. Providing a safety net of information has the potential to reduce morbidity and avoidable mortality and has been shown to reduce re-consultation safely.AimOur research programme aims to provide parents with information they can use to help them determine when to seek help for an acutely ill child.MethodOur programme includes: ASK SARA, a systematic review of existing interventions; ASK PIP, qualitative exploration of safety netting information used by parents and professionals; ASK SID, development of the content and delivery modes for the intervention; ASK ViC, video capture of children with acute illness; and ASK Petra, safety netting tool development using consensus methodology.ResultsThe ASK SNIFF programme findings demonstrate the need for professionally endorsed and co-produced safety netting resources focussing on symptoms of acute childhood illness. We now have consensus on the scripted content for a safety netting tool supported by video materials to enable parents to see symptoms for real.ConclusionSafety netting tools are a valuable aid to general practice enabling GPs to show parents what to look out for when their child is sick so that they know when to (re)consult. Recent reports of failure to recognise and appropriately safety net children with sepsis highlights the importance of such tools.

Abstract Background Most existing research on rural–urban health inequalities focuses on disparities in service access and health outcomes based on region. This paper examines rural–urban disparities in maternal healthcare utilization and delivery modes based on household registration (hukou) status to understand the role of state institutions in producing healthcare disparities in China. Methods Utilizing administrative data from the Public Maternal Health Insurance scheme, we analyzed 54,733 live births in City A (2015–2019) and 25,849 live births in City B (2018–2019) in Guangdong Province in China. We constructed regression models using hukou status (rural versus urban) as the explanatory variable. Results While there is no statistically significant difference in rural and urban mothers’ probability of obtaining the minimum recommended number of prenatal care checkups in City A (OR = 0.990 [0.950, 1.032]), mothers with rural hukou status have a lower probability of obtaining the minimum recommended number of visits in City B than their counterparts with urban hukou (OR = 0.781 [0.740, 0.825]). The probability of delivering in tertiary hospital is lower among mothers with rural hukou than among those with urban hukou in both cities (City A: OR = 0.734 [0.701, 0.769]; City B: OR = 0.336 [0.319, 0.354]). Mothers with rural hukou are more likely to have a Cesarean section than those with urban hukou in both cities (City A: OR = 1.065 [1.027, 1.104]; City B: OR = 1.127 [1.069, 1.189]). Compared with mothers with urban hukou, mothers with rural hukou incurred 4 % (95 % CI [-0.046, -0.033]) and 9.4 % (95 % CI [-0.120, -0.068]) less in total medical costs for those who delivered via Cesarean section and 7.8 % (95 % CI [-0.085, -0.071]) and 19.9 % (95 % CI [-0.221, -0.177]) less for those who delivered via natural delivery in City A and City B, respectively. Conclusions Rural hukou status is associated with younger age, no difference or lower probability of having a minimum number of prenatal checkups, higher likelihood of delivering in nontertiary hospitals, increased Cesarean delivery rates, and lower medical cost for delivery in these two Chinese cities. Evaluating how hukou status influences maternal healthcare in Chinese cities is important for devising targeted public policies to promote more equitable maternal health services.

Index Policies

Nash (1980) demonstrated that index policies are optimal for a class of generalised bandit problem. A transform of the index concerned has many of the attributes of the Gittins index. The transformed index is positive-valued, with maximal values yielding optimal actions. It may be characterised as the value of a restart problem and is hence computable via dynamic programming methodologies. The transformed index can also be used in procedures for policy evaluation.

The Impact

We investigate the impact of switching penalties on the nature of optimal scheduling policies for systems of parallel queues without arrivals. We study two types of switching penalties incurred when switching between queues: lump sum costs and time delays. Under the assumption that the service periods of jobs in a given queue possess the same distribution, we derive an index rule that defines an optimal policy. For switching penalties that depend on the particular nodes involved in a switch, we show that although an index rule is not optimal in general, there is an exhaustive service policy that is optimal.

How do we ReTool school to make it engaging, empowering and success making for all? At the same time how do we guarantee equity and access so that what our government calls “priority learners”, have the same opportunities for 3rd millennium citizenship as everybody else?   When vast tracts of what is now the Developed World, were opened up by the provision of roads, bridges and railroads, people moved from subsistence and achieved effective citizenship, locally, nationally and globally. The infrastructure that enables access to the new platform for citizenship, the internet, is analogous to the roads, bridges and railroads of yesteryear. The business of retooling requires this infrastructure as a baseline, but real efficacy and agency will only be achieved when environments are enriched by innovation on top of the essential infrastructure.   Retooling School requires a Change Pedagogy Imperative: When essential aspects of learning are amalgamated and new media are used for the reception and delivery modes, the learner experience is completely different. It is more than possible to develop new learner agency, efficacy and leadership in learning. This journey to genuine citizenship will have three major hallmarks: ubiquity anywhere, anytime, any pace, any people learning agency the power to act -informed/empowered/enabled learners connectedness edgeless education, connected minds   We need to: Provide the essential infrastructure and enrich the environment for: local, national and international citizenship of all learners.
