Challenging issues for processing queries specified over large-scale information spaces (for example, Digital Libraries or the World Wide Web) include the diversity of the information sources in terms of their structures, query interfaces and search capabilities, as well as the dynamics of sources continuously being added, removed or upgraded. In this paper, we give an innovative solution for query planning in such environments. The foundation of our solution is the Dynamic Information Integration Model (DIIM) which supports the specification of not only content but also capabilities of resources without requiring the establishment of a uniform integration schema. Besides the development of the DIIM model, contributions of this paper include: (1) the introduction of the notion of fully specified queries that are semantically equivalent to a loosely-specified query; (2) a translation algorithm of a loosely-specified query into a set of semantically equivalent feasible query plans that are consistent with the binding patterns of query templates of the individual sources (capability descriptions in DIIM) and with interrelationships between information sources (expressed as join constraints in DIIM); and (3) a search restriction algorithm for optimizing query processing by pruning the search space into the relevant subspace of a query. The plans obtained by the proposed query planning process which is composed of the search restriction and translation algorithms can be shown to correspond to query plans semantically equivalent to the initial loosely-specified input query.

Abstract Objective Hospital engagement in electronic health information exchange (HIE) has increased over recent years. We aimed to 1) determine the change in adoption of 3 types of information exchange: secure messaging, provider portals, and use of an HIE; and 2) to assess if growth in each approach corresponded to increased ability to access and integrate patient information from outside providers. Methods Panel analysis of all nonfederal, acute care hospitals in the United States using hospital- and year-fixed effects. The sample consisted of 1917 hospitals that responded to the American Hospital Association Information Technology Supplement every year from 2014 to 2016. Results Adoption of each approach increased by 9–15 percentage points over the study period. The average number of HIE approaches used by each hospital increased from 1.0 to 1.4. Adoption of each approach was associated with increased likelihood that providers routinely had necessary outside information of 4.2–12.7 percentage points and 4.5–13.3 percentage points increase in information integration. Secure messaging was associated with the largest increase in both. Adoption of 1 approach increased the likelihood of having outside information by 10.3 percentage points, while adopting a second approach further increased the likelihood by 9.5 percentage points. Trends in number of approaches and integration were similar. Discussion/Conclusion No single HIE tool provided high levels of usable, integrated health information. Instead, hospitals benefited from adopting multiple tools. Policy initiatives that reduce the complexity of enabling high value HIE could result in broader adoption of HIE and use of information to inform care.

Objective: The self-care ability of puerpera is poor, and their health knowledge of maternal and infant and care skills is relatively poor. The aim of our study was to investigate the effect of health information integration based on network platform in the postpartum maternal and infant health care. Methods: A total of 80 maternal women admitted to our hospital from September 2018 to March 2019 were randomly divided into a control group and a study group, with 40 patients in each group. The puerpera in control group received regular telephone visits after discharge. The puerpera in study group received health information integration based on network platform. The uterus recovery of puerpera in two groups at 42 days postpartum, as well as the lochia, bloating, nipple splitting and breastfeeding behaviors were compared. The time of jaundice regression and umbilical cord detachment of neonates in t two groups, as well as the incidence of facial eczema and umbilical inflammation were compared. Results: The uterus recovery rate and exclusive breastfeeding rate of puerpera in study group were higher than those in the control group at 42 days postpartum, and the incidences of abnormal lochia, swollen breasts, and nipple splitting were lower than those in the control group. The difference between the two groups was statistically significant (P < 0.05). The neonates in study group were lower than the observation group in terms of the days of jaundice regression, facial eczema, and umbilical inflammation. The difference between the two groups was statistically significant (P < 0.05). However, there was no significant difference in the days of umbilical cord shedding (P > 0.05). Conclusions: The health information integration based on network platform in postpartum maternal and infant health care can effectively improve maternal breastfeeding compliance and reduce the adverse symptoms of maternal and neonatal discharge.
