Human resource assignment and role representation mechanism with the "cascading staff-group authoring" and "relation/situation" model.
We have previously reported the access control mechanism and audit strategy of the "patient-doctor relation and clinical situation at the point-of-care" model with multi-axial access control matrix (ACM). This mechanism overcomes the deficit of ACM in the aspect of data accessibility but does not resolve the representation of the staff's affiliate and/or plural membership in the complex real world. Care groups inside a department or inter-department clinical team plays significant clinical role but also spend great amount of time and money in the hospital. Therefore the impact of human resource assignment and cost of such stakeholders to the hospital management is huge, so that they should be accurately treated in the hospital information system. However multi-axial ACM has problems with the representation of staff groups due to static parameters such as department/license because staffs belong to a group rather temporarily and/or a medical staff may belong to plural groups. As a solution, we have designed and implemented "cascading staff-group authoring" method with "relation and situation" model and multi-axial ACM. In this mechanism, (i) a system administrator certifies "group chief certifying person" according to the request and authorization by the department director, (ii) the "group chief certifying person" certifies "group chief(s)", (iii) the "group chief" recruits its members from the medical staffs, and at the same time the "group chief" decides the profit distribution policy of this group. This will enable medical staff to access EMR according to the role he/she plays whether it is as a department staff or as a group member. This solution has worked successfully over the past few years. It provides end-users with a flexible and time-to-time staff-group authoring environment using a simple human-interfaced tool without security breach and without system administration cost. In addition, profit and cost distribution is clarified among departments and inter-departments groups.
