One example is recognition of concurrent activities in hospital operating rooms based on multiple wearable and embedded sensors. This problem differs from standard time series classification in that there is no natural single target dimension, as multiple activities are performed at the same time. Hence, most existing approaches fail. The key innovations that allow us to tackle this problem is (1) learning to recognize base activities from raw sensor data, (2) creating artificial joint activities from base activities using frequent pattern mining and (3) handling temporal dependency using virtual evidence boosting.

Com este estudo pretende-se traçar uma recente perspectivação dos sistemas de informação arquivística hospitalares, essenciais para a preservação da documentação e a futura investigação histórica em matéria de saúde pública, sem esquecer a sua extrema importância para a gestão das instituições e no auxílio à prática clínica baseada na evidência. A metodologia a ser utilizada, para além da revisão bibliográfica, baseia-se na análise crítica aos resultados de um questionário enviado a uma amostra representativa de instituições hospitalares portuguesas, após devido tratamento estatístico.

This study is a diagnosis of current situation of healthcare information systems, with special attention to the archival information systems in Portugal. It is a recent perspectivation of archival information systems in hospitals, essential to the preservation of documentation and to improve future historical research in public health, not to mention its importance to the management of institutions and aid in clinical practice based on evidence. The methodology to be used, in addition to the literature review, is based on critical analysis of the results of a questionnaire sent to a representative sample of Portuguese hospitals, after due statistical treatment.

The evaluation was performed by means of an in-depth case study with patients and
staff of a public health care organization, using qualitative and quantitative data. On the one hand, the system had consequences perceived as positive such as improved convenience and democratization of specialized treatment for patients and improvements in work organization. On the other hand, negative outcomes were reported, like difficulties faced by
employees due to little familiarity with IT and an increase in the time needed to schedule appointments. Results show
the ambiguity of the implications of HIS in developing countries, emphasizing the need for a more nuanced view of the
evaluation of failures and successes and the importance of social contextual factors.

Recommendation for Electronic Health Records in Haiti

After the 2010 earthquake, much of the infrastructure in the capital area was destroyed, including many hospitals and clincics. The paper-based records stored within were destroyed. Many tent-hospitals staffed by international volunteers had to treat trauma patients without any sort of medical record. An electronics health record (EHR) system could have maintained records for use in this crisis. This paper analyzes several EHR systems that have been implemented in the past in countries with HDI similar to Haiti, develops a typology for analyzing these systems, and proposes a path toward implementing a new EHR system.

A Framework for Evaluating the Appropriateness of Clinical Decision Support Alerts and Responses

by Allison McCoy

McCoy AB, Waitman LR, Lewis JB, Wright JA, Choma DP, Miller RA, Peterson JF. “A Framework for Evaluating the Clinical Impact of Computerized Medication Safety Alerts.” Journal of the American Medical Informatics Association. 2011 Aug 17. [Epub]

Recent reports of suboptimal alert system design and implementation highlight the need for better evaluation to inform future designs. The authors present a comprehensive framework for evaluating the clinical appropriateness of synchronous, interruptive medication safety alerts.
Methods: Through literature review and iterative testing, we developed metrics that describe successes, justifiable overrides, provider non-adherence, and unintended adverse consequences of CDS alerts. We validated the framework by applying it to a medication alerting system for patients with acute kidney injury (AKI).
Results: Through expert review, the framework assesses each alert episode for appropriateness of the alert display and the necessity and urgency of a clinical response. Primary outcomes of the framework include the false positive alert rate, alert override rate, provider non-adherence rate, and rate of provider response appropriateness. Application of the framework to evaluate an existing AKI medication alerting system provided a more complete understanding of the process outcomes measured in the AKI medication alerting system. We confirmed that previous alerts and provider responses were most often appropriate.
Conclusion: The new evaluation model offers a potentially effective method to assess the clinical appropriateness of synchronous interruptive medication alerts prior to evaluating patient outcomes in a comparative trial. More work can determine the generalizability of the framework for use in other settings and other alert types.

Computerization of workflows, guidelines and care pathways: a review of implementation challenges for process-oriented health information systems

by Phil Gooch

In this review, we analyze the challenges in developing process-oriented HIS that formally model guidelines, workflows, and care pathways.

Methods: A qualitative meta-synthesis was performed on studies published in English between 1995 and 2010 that addressed the modeling process and reported the exposition of a new methodology, model, system implementation, or system architecture. Thematic analysis, principal component analysis (PCA) and data visualisation techniques were used to identify and cluster the underlying implementation ‘challenge’ themes.

Results: One hundred and eight relevant studies were selected for review. Twenty-five underlying ‘challenge’ themes were identified. These were clustered into 10 distinct groups, from which a conceptual model of the implementation process was developed.

Discussion and conclusion: We found that the development of systems supporting individual clinical decisions is evolving toward the implementation of adaptable care pathways on the semantic web, incorporating formal, clinical, and organizational ontologies, and the use of workflow management systems. These architectures now need to be implemented and evaluated on a wider scale within clinical settings.
