An experimental electronic patient record for stroke patients. Part 1: situation analysis

Problem-oriented patient record model as a conceptual foundation for a multi-professional electronic patient record

OBJECTIVE

It is widely accepted that the development of electronic patient records, or even of a common electronic patient record, is one possible way to improve cooperation and data communication between nurses and physicians. Yet, little has been done so far to develop a common conceptual model for both medical and nursing patient records, which is a first challenge that should be met to set up a common electronic patient record. In this paper, we describe a problem-oriented conceptual model and we show how it may suit both nursing and medical perspectives in a hospital setting.

METHODS

We started from existing nursing theory and from an initial model previously set up for primary care. In a hospital pilot site, a multi-disciplinary team refined this model using one large and complex clinical case (retrospective study) and nine ongoing cases (prospective study). An internal validation was performed through hospital-wide multi-professional interviews and through discussions around a graphical user interface prototype. To assess the consistency of the model, a computer engineer specified it. Finally, a Belgian expert working group performed an external assessment of the model.

RESULTS

As a basis for a common patient record we propose a simple problem-oriented conceptual model with two levels of meta-information. The model is mapped with current nursing theories and it includes the following concepts: "health care element", "health approach", "health agent", "contact", "subcontact" and "service". These concepts, their interrelationships and some practical rules for using the model are illustrated in this paper. Our results are compatible with ongoing standardization work at the Belgian and European levels.

CONCLUSIONS

Our conceptual model is potentially a foundation for a multi-professional electronic patient record that is problem-oriented and therefore patient-centred.

Information access at the point of care: what can we learn for designing a mobile CPR system?

OBJECTIVES

Hospitals have started to migrate their paper-based records to computerized patient records (CPR). The majority of today's CPR systems are stationary, which means that physicians use a clinical workstation to access CPR information. But health care professionals need to request and enter information at different locations, for example, on their daily ward round. This suggests the use of mobile computers, enabling an ubiquitous access to needed data. Different studies show that health care professionals are reluctant to use poorly designed mobile CPR systems, as the work at the point of care is very time-pressured and hectic. To design a system with high acceptance, it is essential to obtain empirical insight into the work practices and context in which the mobile CPR system will be used.

METHOD

We investigated the physicians' work with the patient record during their daily round. With the help of a compact notation method, the physicians' interaction with the information system was recorded in real time. Fourteen physicians from three different departments (internal medicine, surgery, and geriatrics) of a middle-sized Swiss hospital participated in our study.

RESULTS

Physicians have clear access preferences when they interact with the patient record during their daily round. There exists a clear profile of access frequencies and patterns, respectively. As an example, approximately 50% of all patient record accesses concern information about medications, vital signs and lab test results.

DISCUSSION/CONCLUSION

A CPR system which is designed to reflect the access frequencies and patterns should improve the efficiency of data entry and retrieval and thus result in a system with high acceptance among physicians in the demanding environment during hospital rounds.

Development and implementation of an EPR: how to encourage the user

This paper reports on the role users played in the design and development of an electronic patient record. Two key users participated in the project team. All future users received questionnaires and a selection of them was interviewed. Before starting the development of the EPR, the attitude of users towards electronic record keeping, their satisfaction with the paper clinical records, their knowledge of computers, and their needs and expectations of computer applications in health care were measured by means of a questionnaire. The results of the questionnaire were supplemented with in-depth interviews. Users had a neutral attitude towards electronic record keeping. They were more positive about data entry of the paper records than data retrieval. During the development phase, but prior to the implementation of the EPR, a second questionnaire measured satisfaction with the paper records. Satisfaction appeared to be related to self-rated computer experience. Inexperienced computer users tended to be more positive about the paper records. In general, respondents did not have many expectations about electronic record keeping. A second series of interviews zoomed in on the expectations users had. Except for more concise reporting no beneficial effects of electronic record keeping were expected.

An experimental electronic patient record for stroke patients. Part 2: system description

This article presents an electronic patient record (EPR) for stroke patients. At the neurology department of the Maastricht University Hospital, coordination and communication of the multidisciplinary team for stroke patients is intended to be supported by an EPR. Existing, structured, paper nursing and medical records served as a starting point for the development of the EPR. In close cooperation with future users, the database structure, and data entry and data retrieval aspects of the user interface were adapted to the domain of stroke. The result is a combined electronic medical and nursing record that has potential to improve record keeping and to truly support daily routines. The challenges encountered in the development process were maintaining continuous user involvement and conflicting points of view regarding the relevance of clinical data. Conclusively, we state that intensive user participation improved the EPR, coupling with the existing hospital information system and other systems will be advantageous and the fact that the paper records were structured in advance will smooth the unavoidable changes in work patterns.
