Investigating public health emergency response information system initiatives in China

Infectious diseases pose a great danger to public health internationally. The outbreak of SARS has exposed China's fragile public health system and its limited ability to detect and respond to emergencies in a timely and effective manner. In order to strengthen its capability of responding to future public health emergencies, China is developing a public health emergency response information system (PHERIS) to facilitate disease surveillance, detection, reporting, and response. The purpose of this study is to investigate the ongoing development of China's PHERIS. This paper analyzes the problems of China's existing public health system and describes the design and functionalities of PHERIS from both technical and managerial aspects.     

Ethical issues in public health informatics: implications for system design when sharing geographic information

Public health programs today constitute a multi-professional inter-organizational environment, where both health service and other organizations are involved. Developing information systems, including the IT security measures needed to suit this complex context, is a challenge. To ensure that all involved organizations work together towards a common goal, i.e., promotion of health, an intuitive strategy would be to share information freely in these programs. However, in practice it is seldom possible to realize this ideal scenario. One reason may be that ethical issues are often ignored in the system development process. This investigation uses case study methods to explore ethical obstacles originating in the shared use of geographic health information in public health programs and how this affects the design of information systems. Concerns involving confidentiality caused by geographically referenced health information and influences of professional and organizational codes are discussed. The experience presented shows that disregard of ethical issues can result in a prolonged development process for public health information systems. Finally, a theoretical model of design issues based on the case study results is presented.     

Scenario-based design: a method for connecting information system design with public health operations and emergency management

Responding to public health emergencies requires rapid and accurate assessment of workforce availability under adverse and changing circumstances. However, public health information systems to support resource management during both routine and emergency operations are currently lacking. We applied scenario-based design as an approach to engage public health practitioners in the creation and validation of an information design to support routine and emergency public health activities. Methods: Using semi-structured interviews we identified the information needs and activities of senior public health managers of a large municipal health department during routine and emergency operations. Results: Interview analysis identified 25 information needs for public health operations management. The identified information needs were used in conjunction with scenario-based design to create 25 scenarios of use and a public health manager persona. Scenarios of use and persona were validated and modified based on follow-up surveys with study participants. Scenarios were used to test and gain feedback on a pilot information system. Conclusion: The method of scenario-based design was applied to represent the resource management needs of senior-level public health managers under routine and disaster settings. Scenario-based design can be a useful tool for engaging public health practitioners in the design process and to validate an information system design.     

Building the national health information infrastructure for personal health, health care services, public health, and research

Background  

Improving health in our nation requires strengthening four major domains of the health care system: personal health management, health care delivery, public health, and health-related research. Many avoidable shortcomings in the health sector that result in poor quality are due to inaccessible data, information, and knowledge. A national health information infrastructure (NHII) offers the connectivity and knowledge management essential to correct these shortcomings. Better health and a better health system are within our reach.     

National efforts to improve health information system safety in Canada,the United States of America and England

ObjectiveIn this paper we review progress as well as challenges encountered in Canada, the United States and England with regard to ensuring safety of health information technology.MethodA review of major programs and initiatives for ensuring safety of health information technology in the three countries was conducted. Published literature and Web resources from national programs were reviewed for relevant information.ResultsIt was found that in all three countries the issue of technology-induced error has been recognized as being of critical importance. The three countries have developed approaches for dealing with the issue that have some commonalities; however, they are at varying different stages of maturity, with England having the longest standing and most well developed safety programs, while Canada and the United States are at earlier stages. The types of approaches employed have included work on developing standards related to usability and interface design, certifications, directives from regulatory bodies, educational initiatives in health information technology (HIT) safety as well as research into safer HIT design and implementation methods.ConclusionsHIT promises to lead to improved patient safety. However, it has become recognized that if not designed and deployed appropriately, such systems can lead to new types of errors. Based on this recognition, a variety of initiatives are being undertaken in Canada, the United States and England to promote the safe design, procurement and deployment of HIT. It is concluded that improved approaches to system design, testing, regulation, error reporting, safety education and cross-country collaboration will be needed to further promote safer HIT.     

Consumer health information technology in an adult public health primary care clinic: A heart health education feasibility study

Objective

To explore the feasibility and short term outcomes of using an interactive kiosk integrated into office flow to deliver health information in a primary care clinic.

Methods

Fifty-one adults with BMI ≥25 were randomly assigned to use a kiosk with attached devices to receive a six-week healthy eating/weight monitoring (intervention) or general health/BP monitoring (attention-control) program. Outcomes were measured at baseline, 8 weeks (post) and three month follow-up.

Results

Participants completed an average of 2.73 weekly sessions, with transportation and time given as limiting factors. They found the kiosk easy to use (97%), liked the touchscreen (94%), and would use the kiosk again (81%). Although there were no differences between groups, the 27 completing all assessments showed reduced weight (p = .02), and decreased systolic (p = .01) and diastolic BP (p < .001) at follow-up. Although healthy eating behaviors increased, the change was not statistically significant.

Conclusion

Using a kiosk within a clinic setting is a feasible method of providing health information and self-monitoring. Multi-session educational content can provide beneficial short-term outcomes in overweight adults.

Practice implications

A kiosk with attached peripherals in a clinic setting is a viable adjunct to provider education, particularly in medically underserved areas.

Improved HIV-related outcomes associated with implementation of a novel public health information exchange

PurposeThe purpose of this study was to evaluate HIV-related outcomes associated with use of a novel public health information exchange that was designed to identify out of care HIV-infected individuals seen within a large, integrated delivery network (IDN).MethodsA novel, secure, bidirectional health care delivery-public health information exchange, the Louisiana Public Health Information Exchange (LaPHIE) was developed between a multi-geographical IDN and the Louisiana public health authority in response to the high proportion of out of care HIV-infected persons. The system provides real-time provider alerts when any HIV-infected person who has not had CD4 or HIV viral load (VL) monitoring in >1 year receives non-HIV care within the IDN, allowing immediate linkage to HIV specialty care. Persons identified over the first 30 months of the system's implementation were characterized using a case-cohort approach to compare out-of-care individuals with randomly sampled, time-matched in-care controls.ResultsBetween 2/1/09 and 7/31/11, 549 alerts identified 419 unduplicated HIV-infected individuals without a CD4 count or VL in >1 year. Patients were identified at 60 clinics and alerts shown to 223 clinicians in 7 participating facilities. A quarter (24%) of those identified had not had a CD4 count or VL conducted since their initial diagnosis. Of the remaining 76% who had been in care previously, over half (55%) had been out of care for ≥18 months, with a median time of 19.4 months [IQR 15.0–32.5] since their previous visit. Following LaPHIE identification, 42% had CD4 counts < 200 cells/mm³ and 62% had VL > 10,000 RNA copies/mL. Of the 344 patients with at least 6 months of follow up, 85% had at least one CD4 and/or VL test after being identified.ConclusionsThe results of this study demonstrate that an information exchange can effectively facilitate engagement, re-engagement, and retention of out-of care HIV-infected persons in HIV specialty care. Within two years, we were able to observe significant improvements in HIV-related utilization and disease progression indices. Future programs should consider adopting this innovative strategy to improve HIV care at both the individual and population levels.

The key steps of this method are based on semantic interoperability. Relevant data elements and datasets with semantic interoperability are selected. Moreover, an information standard system is constructed, and the information standardization requirements of the PHIS are met.

     

An information system for drug prescription and distribution in a public hospital

With 773 beds and 3696 employees, the Hospital das Clínicas da Faculdade de Medicina de Ribeir?o Preto (HCFMRP)-Universidade de S?o Paulo, is one of the largest medical institutions in Latin America. The complete process of prescribing and distributing medication at HCFMRP involves the following stages: prescribing (physicians); ordering (infirmary); separating and dispensing (main drugstore); verifying and administering (infirmary). This was a manual process, normally taking place in the morning. Bottlenecks were inevitable and the risk of errors was elevated. An information system (IS) was devised and implemented with a view to controlling such problems. This article addresses the construction of this system and reports on a survey in which different groups of users have evaluated the project.     

Description of a method to support public health information management: organizational network analysis

In this case study, we describe a method that has potential to provide systematic support for public health information management. Public health agencies depend on specialized information that travels throughout an organization via communication networks among employees. Interactions that occur within these networks are poorly understood and are generally unmanaged. We applied organizational network analysis, a method for studying communication networks, to assess the method's utility to support decision making for public health managers, and to determine what links existed between information use and agency processes. Data on communication links among a health department's staff was obtained via survey with a 93% response rate, and analyzed using Organizational Risk Analyzer (ORA) software. The findings described the structure of information flow in the department's communication networks. The analysis succeeded in providing insights into organizational processes which informed public health managers' strategies to address problems and to take advantage of network strengths.     

Understanding the information needs of public health practitioners: a literature review to inform design of an interactive digital knowledge management system

The need for rapid access to information to support critical decisions in public health cannot be disputed; however, development of such systems requires an understanding of the actual information needs of public health professionals. This paper reports the results of a literature review focused on the information needs of public health professionals. The authors reviewed the public health literature to answer the following questions: (1) What are the information needs of public health professionals? (2) In what ways are those needs being met? (3) What are the barriers to meeting those needs? (4) What is the role of the Internet in meeting information needs? The review was undertaken in order to develop system requirements to inform the design and development of an interactive digital knowledge management system. The goal of the system is to support the collection, management, and retrieval of public health documents, data, learning objects, and tools.Method:The search method extended beyond traditional information resources, such as bibliographic databases, tables of contents (TOC), and bibliographies, to include information resources public health practitioners routinely use or have need to use—for example, grey literature, government reports, Internet-based publications, and meeting abstracts.Results:Although few formal studies of information needs and information-seeking behaviors of public health professionals have been reported, the literature consistently indicated a critical need for comprehensive, coordinated, and accessible information to meet the needs of the public health workforce. Major barriers to information access include time, resource reliability, trustworthiness/credibility of information, and “information overload”.Conclusions:Utilizing a novel search method that included the diversity of information resources public health practitioners use, has produced a richer and more useful picture of the information needs of the public health workforce than other literature reviews. There is a critical need for public health digital knowledge management systems designed to reflect the diversity of public health activities, to enable human communications, and to provide multiple access points to critical information resources. Public health librarians and other information specialists can serve a significant role in helping public health professionals meet their information needs through the development of evidence-based decision support systems, human-mediated expert searching and training in the use information retrieval systems.     

A four stage approach for ontology-based health information system design

ObjectiveTo describe and illustrate a four stage methodological approach to capture user knowledge in a biomedical domain area, use that knowledge to design an ontology, and then implement and evaluate the ontology as a health information system (HIS).Methods and materialsA hybrid participatory design-grounded theory (GT-PD) method was used to obtain data and code them for ontology development. Prototyping was used to implement the ontology as a computer-based tool. Usability testing evaluated the computer-based tool.ResultsAn empirically derived domain ontology and set of three problem-solving approaches were developed as a formalized model of the concepts and categories from the GT coding. The ontology and problem-solving approaches were used to design and implement a HIS that tested favorably in usability testing.ConclusionsThe four stage approach illustrated in this paper is useful for designing and implementing an ontology as the basis for a HIS. The approach extends existing ontology development methodologies by providing an empirical basis for theory incorporated into ontology design.
