Strengthen Cancer Surveillance in Sri Lanka by Implementing Cancer Registry Informatics to Enhance Cancer Registry Data Accuracy, Completeness, and Timeliness

Cancer surveillance is a process of systematic, continuous collection, storage, analysis, interpretation and dissemination of epidemiological information on cancer cases occurring in a particular geographic area. The process of cancer surveillance is also called 'cancer registration'. A system to conduct cancer registration is called 'cancer registry'. The purpose of the project is to implement cancer registry informatics to enhance electronic cancer registry reporting activities that take advantage of emerging health information technology. The expected function of the application is to strengthen the cancer registry data accuracy, completeness, and timeliness. The goals to be achieved are: determine the incidence of cancers with respect to geographic, demographic characteristics; monitor trends and patterns of cancer incidences over time; identify high-risk populations; provide data for epidemiological studies and prioritize health resource allocations.

Managing User Needs During the EHR Implementation in Buenos Aires City: The HelpDesk Role

Enablement, guidance, and proactive preparation for a new IT system implementation has proven to be a smart way to prepare people to embrace change. These activities are closely related to change management approaches which seek to help people understand and adopt specific behaviors. That being said, investing in such activities becomes the cornerstone of the success of the project. Leading IT companies around the world include in their strategy for new services and offering deployments, a proactive HelpDesk service. This not only helps build long lasting/trusted relationships between end users and IT sectors but also helps reduce cost and maximizes the Return of Investment. A streamlined process and easy to use/fluent communication channel between parties are powerful risk management/Quality Assurance and Continuous Improvement tools. In this paper, we address the example of a HelpDesk support team implementation of a city-scaled Electronic Health Records implementation.

Factors Influencing the Implementation and Distribution of Clinical Decision Support Systems (CDSS)

Clinical Decision Support Systems (CDSS) can have positive effects on quality of care measures, yet have not gained widespread traction in healthcare. This study sought to determine and evaluate barriers and facilitators to CDSS implementation and distribution. Based on 768 systems identified in a literature review we conducted semi-structured telephone interviews with 54 system developers in 16 countries. Qualitative analysis led to the identification of 66 key factors influencing implementation. Central issues evolved around CDSS properties, quality and integration, as well as usability, user related factors, internal marketing, resource issues and collaborations with emphasis partly on topics differing from existing research. Additionally, evidence pointed to regional differences regarding implementation hurdles. Recent regulatory requirements were deemed less of a barrier to system adoption than expected, even though lacking expertise in this area was surprisingly common among interview partners.

Evaluation of an Integrated Health Information System (HIS) in a Public Hospital in Cyprus: A Pilot Study

Health information systems can improve the quality of services in healthcare. Evaluation of health information systems in hospitals is a very complex process, and it is more effective when different aspects are considered. The present work aims to develop an evaluation framework of an integrated HIS in order to improve the quality of healthcare services provided in Cyprus. Qualitative and quantitative methods were used, that measured three aspects of the system: technology, human factor and organization. Preliminary results showed that while participants seem to agree with the potential benefits of the integrated HIS, safety of data within the HIS is seen as a problem. Qualitatively, the study pointed to 3 factors that might improve the current integrated HIS: increasing interdisciplinary cooperation, training of staff, and upgrading the infrastructure. Further studies will provide a comprehensive picture for Cyprus, so that appropriate measures can be proposed and put in action.

Towards a Usability and Error "Safety Net": A Multi-Phased Multi-Method Approach to Ensuring System Usability and Safety

The usability and safety of health information systems have become major issues in the design and implementation of useful healthcare IT. In this paper we describe a multi-phased multi-method approach to integrating usability engineering methods into system testing to ensure both usability and safety of healthcare IT upon widespread deployment. The approach involves usability testing followed by clinical simulation (conducted in-situ) and "near-live" recording of user interactions with systems. At key stages in this process, usability problems are identified and rectified forming a usability and technology-induced error "safety net" that catches different types of usability and safety problems prior to releasing systems widely in healthcare settings.

Using Semantic Technologies to Extract Highlights from Care Notes

We propose a cognitive system for patient-centric care that leverages and combines natural language processing, semantics, and learning from users over time to support care professionals working with large volumes of patient notes. The proposed methods highlight the entities embedded in the unstructured data to provide a holistic semantic view of an individual. A user-based evaluation is presented, showing consensus between the users and the system.

The Future of Mobile Usability, Workflow and Safety Testing

In this paper, the authors outline a vision for the future of mobile usability, workflow and safety testing. The authors argue for the use of glasses that can audio and video record usability, workflow and safety data. Here, citizens, patients and health professionals would become collectors of study data as they use mobile devices and software to support healthcare in the real world. This has become quite feasible with the introduction of low-cost glasses and software applications that allow for the uploading of data for additional analysis by researchers and evaluators of mobile technologies.

Comparative Performance Analysis of Different Fingerprint Biometric Scanners for Patient Matching

Unique patient identification within health services is an operational challenge in healthcare settings. Use of key identifiers, such as patient names, hospital identification numbers, national ID, and birth date are often inadequate for ensuring unique patient identification. In addition approximate string comparator algorithms, such as distance-based algorithms, have proven suboptimal for improving patient matching, especially in low-resource settings. Biometric approaches may improve unique patient identification. However, before implementing the technology in a given setting, such as health care, the right scanners should be rigorously tested to identify an optimal package for the implementation. This study aimed to investigate the effects of factors such as resolution, template size, and scan capture area on the matching performance of different fingerprint scanners for use within health care settings. Performance analysis of eight different scanners was tested using the demo application distributed as part of the Neurotech Verifinger SDK 6.0.

Effective Usability Engineering in Healthcare: A Vision of Usable and Safer Healthcare IT

Persistent problems with healthcare IT that is unusable and unsafe have been reported worldwide. In this paper we present our vision for deploying usability engineering in healthcare in a more substantive way in order to improve the current situation. The argument will be made that stronger and more substantial efforts need to be made to bring multiple usability engineering methods to bear on points in both system design and deployment (and not just as a one-time effort restricted to software product development). In addition, improved processes for ensuring the usability of commercial vendor-based systems being implemented in healthcare organizations need to be addressed. A discussion will also be provided on challenges and barriers that will need to be overcome to ensure that the heatlhcare IT that is released is both usable and safe.

Automated Transformation of CDISC ODM to OpenClinica

Due to the increasing use of electronic data capture systems for clinical research, the interest in saving resources by automatically generating and reusing case report forms in clinical studies is growing. OpenClinica, an open-source electronic data capture system enables the reuse of metadata in its own Excel import template, hampering the reuse of metadata defined in other standard formats. One of these standard formats is the Operational Data Model for metadata, administrative and clinical data in clinical studies. This work suggests a mapping from Operational Data Model to OpenClinica and describes the implementation of a converter to automatically generate OpenClinica conform case report forms based upon metadata in the Operational Data Model.

An Incremental Adoption Pathway for Developing Precision Medicine Based Healthcare Infrastructure for Underserved Settings

Recent focus on Precision medicine (PM) has led to a flurry of research activities across the developed world. But how can understaffed and underfunded health care systems in the US and elsewhere evolve to adapt PM to address pressing healthcare needs? We offer guidance on a wide range of sources of healthcare data / knowledge as well as other infrastructure / tools that could inform PM initiatives, and may serve as low hanging fruit easily adapted on the incremental pathway towards a PM based healthcare system. Using these resources and tools, we propose an incremental adoption pathway to inform implementers working in underserved communities around the world on how they should position themselves to gradually embrace the concepts of PM with minimal interruption to existing care delivery.

Multivariate and Longitudinal Health System Indicators

Within population health information systems, indicators are commonly presented as independent, cross-sectional measures, neglecting the multivariate, longitudinal nature of disease progression, health care use, and profiles of performance. We use administrative claims data of Montreal, Canada to identify patterns across indicators and over time in chronic obstructive pulmonary disease patients. We first cluster regions based on four health service indicators. Our second approach discovers individual-level trajectories based on a hidden Markov model using the same four indicators. Both approaches offer additional insights by facilitating the discovery and interpretation of indicators, such as a dual interpretation of low use of general practitioner services. These approaches to the analysis and visualization of health indicators can provide a foundation for information displays that will help decision makers identify areas of concern, predict future disease burden, and implement appropriate policies.

The quality of morbidity data in multiple routine inpatient records in a sample of South African hospitals is being assessed in terms of data accuracy and completeness. Extensive modification of available data collection tools was required to make it possible to collect the required data for the study.

Prevalence of Childhood Obesity by Sex and Regions in Peru, 2015

OBJECTIVE

Childhood obesity is a global problem, sociodemographic and cultural factors influence its presence. An analysis of disparities in the prevalence of childhood obesity in Peru was made by sex and region in 2015.

METHODS

Analysis of the information reported by the Sistema de Información del Estado Nutricional of the number of obesity cases in 2,336,791 children under five years, evaluated in public health facilities during 2015. The distribution of obesity cases was analyzed by sex and region of residence, also a spatial projection of the regional prevalence of obesity and the prevalence differences between men and women was performed.

RESULTS

Data from 2,336,791 children under five was analyzed. An obesity prevalence of 1.52% (girls: 1.3% and boys: 1.7%) was found; the highest prevalence were observed in urban areas (girls: 1.5% and boys: 1.9%) and on the Costa (girls: 1.9% and boys: 2.5%). Highest prevalence of obesity were in Tacna (girls: 3.2% y boys: 3.9%), Moquegua (girls: 2.4% y boys: 3.1%) and Callao (girls: 2.3% y boys: 2.8%).

CONCLUSIONS

Childhood obesity predominates on the coast and in urban areas of Peru particularly among boys. The regions of higher prevalence of obesity were Tacna Moquegua and Callao.

Commentary: A lack of a comparator group makes it hard to be sure whether computerised medical record system implementation achieved a better or worse outcome

Convergence of Health Level Seven Version 2 Messages to Semantic Web Technologies for Software-Intensive Systems in Telemedicine Trauma Care

Objectives

To present the technical background and the development of a procedure that enriches the semantics of Health Level Seven version 2 (HL7v2) messages for software-intensive systems in telemedicine trauma care.

Methods

This study followed a multilevel model-driven approach for the development of semantically interoperable health information systems. The Pre-Hospital Trauma Life Support (PHTLS) ABCDE protocol was adopted as the use case. A prototype application embedded the semantics into an HL7v2 message as an eXtensible Markup Language (XML) file, which was validated against an XML schema that defines constraints on a common reference model. This message was exchanged with a second prototype application, developed on the Mirth middleware, which was also used to parse and validate both the original and the hybrid messages.

Results

Both versions of the data instance (one pure XML, one embedded in the HL7v2 message) were equally validated and the RDF-based semantics recovered by the receiving side of the prototype from the shared XML schema.

Conclusions

This study demonstrated the semantic enrichment of HL7v2 messages for intensive-software telemedicine systems for trauma care, by validating components of extracts generated in various computing environments. The adoption of the method proposed in this study ensures the compliance of the HL7v2 standard in Semantic Web technologies.

Chronic Heart Failure Follow-up Management Based on Agent Technology

Objectives

Monitoring heart failure patients through continues assessment of sign and symptoms by information technology tools lead to large reduction in re-hospitalization. Agent technology is one of the strongest artificial intelligence areas; therefore, it can be expected to facilitate, accelerate, and improve health services especially in home care and telemedicine. The aim of this article is to provide an agent-based model for chronic heart failure (CHF) follow-up management.

Methods

This research was performed in 2013-2014 to determine appropriate scenarios and the data required to monitor and follow-up CHF patients, and then an agent-based model was designed.

Results

Agents in the proposed model perform the following tasks: medical data access, communication with other agents of the framework and intelligent data analysis, including medical data processing, reasoning, negotiation for decision-making, and learning capabilities.

Conclusions

The proposed multi-agent system has ability to learn and thus improve itself. Implementation of this model with more and various interval times at a broader level could achieve better results. The proposed multi-agent system is no substitute for cardiologists, but it could assist them in decision-making.

Impact of and Satisfaction with a New eConsult Service: A Mixed Methods Study of Primary Care Providers

OBJECTIVES

We have improved access to specialist care and decreased wait times in our region through the development and implementation of the Champlain BASE (Building Access to Specialists through eConsultation) service. This secure, web-based tool allows primary care providers (PCPs) quick access to specialist advice for their patients and often helps to avoid the need for a face-to-face referral. Our successful implementation of eConsult in our region provides a unique opportunity to examine PCPs' satisfaction and overall perspective on using the service.

METHODS

Following the closure of each case, PCPs completed a short survey with multiple-choice and open-ended questions regarding the eConsult. All eConsults submitted between April 15, 2011, and December 31, 2013, were analyzed. We calculated satisfaction scores from the survey and conducted a constant-comparison thematic analysis on those cases where the PCP elected to leave a text response.

RESULTS

We analyzed 2,052 eConsults completed during the study period. In 91% and 93% of eConsults, PCPs reported a high value for their patients and themselves, respectively. In 554 eConsults, PCPs elected to leave a written response. Three major themes emerged: PCP appreciation of the eConsult service, perceived benefits for the quality of patient care, and attitudes towards using a new health technology. High satisfaction was expressed with quick response times, helpfulness of responses, and reassurance reported. Most PCPs felt eConsult had a positive impact on patient care by also providing reassurance to patients, reducing burden of time and travel, and offering educational opportunities to PCPs applicable to future cases.

CONCLUSION

PCPs showed a high level of satisfaction with eConsult's quick turnaround time and quality of specialist advice. Our results illustrate the advantages of using asynchronous virtual platforms to increase access to specialty care from a PCP perspective.

Effects of health information technology on malpractice insurance premiums

OBJECTIVES

The widespread adoption of health information technology (IT) will help contain health care costs by decreasing inefficiencies in healthcare delivery. Theoretically, health IT could lower hospitals' malpractice insurance premiums (MIPs) and improve the quality of care by reducing the number and size of malpractice. This study examines the relationship between health IT investment and MIP using California hospital data from 2006 to 2007.

METHODS

To examine the effect of hospital IT on malpractice insurance expense, a generalized estimating equation (GEE) was employed.

RESULTS

It was found that health IT investment was not negatively associated with MIP. Health IT was reported to reduce medical error and improve efficiency. Thus, it may reduce malpractice claims from patients, which will reduce malpractice insurance expenses for hospitals. However, health IT adoption could lead to increases in MIPs. For example, we expect increases in MIPs of about 1.2% and 1.5%, respectively, when health IT and labor increase by 10%.

CONCLUSIONS

This study examined the effect of health IT investment on MIPs controlling other hospital and market, and volume characteristics. Against our expectation, we found that health IT investment was not negatively associated with MIP. There may be some possible reasons that the real effect of health IT on MIPs was not observed; barriers including communication problems among health ITs, shorter sample period, lower IT investment, and lack of a quality of care measure as a moderating variable.

A case study evaluation of a Critical Care Information System adoption using the socio-technical and fit approach

BACKGROUND

Clinical information systems have long been used in intensive care units but reports on their adoption and benefits are limited. This study evaluated a Critical Care Information System implementation.

METHODS

A case study summative evaluation was conducted, employing observation, interview, and document analysis in operating theatres and 16-bed adult intensive care units in a 400-bed Malaysian tertiary referral centre from the perspectives of users (nurses and physicians), management, and information technology staff. System implementation, factors influencing adoption, fit between these factors, and the impact of the Critical Care Information System were evaluated after eight months of operation.

RESULTS

Positive influences on system adoption were associated with technical factors, including system ease of use, usefulness, and information relevancy; human factors, particularly user attitude; and organisational factors, namely clinical process-technology alignment and champions. Organisational factors such as planning, project management, training, technology support, turnover rate, clinical workload, and communication were barriers to system implementation and use. Recommendations to improve the current system problems were discussed. Most nursing staff positively perceived the system's reduction of documentation and data access time, giving them more time with patients. System acceptance varied among doctors. System use also had positive impacts on timesaving, data quality, and clinical workflow.

CONCLUSIONS

Critical Care Information Systems is crucial and has great potentials in enhancing and delivering critical care. However, the case study findings showed that the system faced complex challenges and was underutilised despite its potential. The role of socio-technical factors and their fit in realizing the potential of Critical Care Information Systems requires continuous, in-depth evaluation and stakeholder understanding and acknowledgement. The comprehensive and specific evaluation measures of the Human-Organisation-Technology Fit framework can flexibly evaluate Critical Care Information Systems.

Development of a master health facility list in Nigeria

Abstract.

INTRODUCTION

Routine Health Information Systems (RHIS) are increasingly transitioning to electronic platforms in several developing countries. Establishment of a Master Facility List (MFL) to standardize the allocation of unique identifiers for health facilities can overcome identification issues and support health facility management. The Nigerian Federal Ministry of Health (FMOH) recently developed a MFL, and we present the process and outcome.

METHODS

The MFL was developed from the ground up, and includes a state code, a local government area (LGA) code, health facility ownership (public or private), the level of care, and an exclusive LGA level health facility serial number, as part of the unique identifier system in Nigeria. To develop the MFL, the LGAs sent the list of all health facilities in their jurisdiction to the state, which in turn collated for all LGAs under them before sending to the FMOH. At the FMOH, a group of RHIS experts verified the list and identifiers for each state.

RESULTS

The national MFL consists of 34,423 health facilities uniquely identified. The list has been published and is available for worldwide access; it is currently used for planning and management of health services in Nigeria.

DISCUSSION

Unique identifiers are a basic component of any information system. However, poor planning and execution of implementing this key standard can diminish the success of the RHIS.

CONCLUSION

Development and adherence to standards is the hallmark for a national health information infrastructure. Explicit processes and multi-level stakeholder engagement is necessary to ensuring the success of the effort.

Seeking health information online: does limited healthcare access matter?

Consumers facing barriers to healthcare access may use online health information seeking and online communication with physicians, but the empirical relationship has not been sufficiently analyzed. Our study examines the association of barriers to healthcare access with consumers' health-related information searching on the internet, use of health chat groups, and email communication with physicians, using data from 27,210 adults from the 2009 National Health Interview Survey. Individuals with financial barriers to healthcare access, difficulty getting timely appointments with doctors, and conflicts in scheduling during clinic hours are more likely to search for general health information online than those without these access barriers. Those unable to get timely appointments with physicians are more likely to participate in health chat groups and email physicians. The internet may offer a low-cost source of health information and could help meet the heightened demand for health-related information among those facing access barriers to care.

Determining of factors influencing the success and failure of hospital information system and their evaluation methods: a systematic review

BACKGROUND

Nowadays, using new information technology (IT) has provided remarkable opportunities to decrease medical errors, support health care specialist, increase the efficiency and even the quality of patient's care and safety.

OBJECTIVES

The purpose of this study was the identification of Hospital Information System (HIS) success and failure factors and the evaluation methods of these factors. This research emphasizes the need to a comprehensive evaluation of HISs which considers a wide range of success and failure factors in these systems.

MATERIALS AND METHODS

We searched for relevant English language studies based on keywords in title and abstract, using PubMed, Ovid Medline (by applying MeSH terms), Scopus, ScienceDirect and Embase (earliest entry to march 17, 2012). Studies which considered success models and success or failure factors, or studied the evaluation models of HISs and the related ones were chosen. Since the studies used in this systematic review were heterogeneous, the combination of extracted data was carried out by using narrative synthesis method.

RESULTS

We found 16 articles which required detailed analysis. Finally, the suggested framework includes 12 main factors (functional, organizational, behavioral, cultural, management, technical, strategy, economy, education, legal, ethical and political factors), 67 sub factors, and 33 suggested methods for the evaluation of these sub factors.

CONCLUSIONS

The results of the present research indicates that the emphasis of the HIS evaluation moves from technical subjects to human and organizational subjects, and from objective to subjective issues. Therefore, this issue entails more familiarity with more qualitative evaluation methods. In most of the reviewed studies, the main focus has been laid on the necessity of using multi-method approaches and combining methods to obtain more comprehensive and useful results.

Nursing informatics: decades of contribution to health informatics

OBJECTIVES

In this paper we present a contemporary understanding of "nursing informatics" and relate it to applications in three specific contexts, hospitals, community health, and home dwelling, to illustrate achievements that contribute to the overall schema of health informatics.

METHODS

We identified literature through database searches in MEDLINE, EMBASE, CINAHL, and the Cochrane Library. Database searching was complemented by one author search and hand searches in six relevant journals. The literature review helped in conceptual clarification and elaborate on use that are supported by applications in different settings.

RESULTS

Conceptual clarification of nursing data, information and knowledge has been expanded to include wisdom. Information systems and support for nursing practice benefits from conceptual clarification of nursing data, information, knowledge, and wisdom. We introduce three examples of information systems and point out core issues for information integration and practice development.

CONCLUSIONS

Exploring interplays of data, information, knowledge, and wisdom, nursing informatics takes a practice turn, accommodating to processes of application design and deployment for purposeful use by nurses in different settings. Collaborative efforts will be key to further achievements that support task shifting, mobility, and ubiquitous health care.

Trends in health information technology safety: from technology-induced errors to current approaches for ensuring technology safety

OBJECTIVES

Health information technology (HIT) research findings suggested that new healthcare technologies could reduce some types of medical errors while at the same time introducing classes of medical errors (i.e., technology-induced errors). Technology-induced errors have their origins in HIT, and/or HIT contribute to their occurrence. The objective of this paper is to review current trends in the published literature on HIT safety.

METHODS

A review and synthesis of the medical and life sciences literature focusing on the area of technology-induced error was conducted.

RESULTS

There were four main trends in the literature on technology-induced error. The following areas were addressed in the literature: definitions of technology-induced errors; models, frameworks and evidence for understanding how technology-induced errors occur; a discussion of monitoring; and methods for preventing and learning about technology-induced errors.

CONCLUSIONS

The literature focusing on technology-induced errors continues to grow. Research has focused on the defining what an error is, models and frameworks used to understand these new types of errors, monitoring of such errors and methods that can be used to prevent these errors. More research will be needed to better understand and mitigate these types of errors.
