AI Article Synopsis

  • OIDs help ensure that identifiers used in cross-system communication are traceable, but there are issues with the current OID registration system.
  • The use of OIDs can create confusion in messages and adds unnecessary redundancy, leading to larger message sizes without providing any new information.
  • Health Level 7's attempt to standardize the use of OIDs outside of network addressing may have inadvertently caused more confusion in cross-system communications.

Article Abstract

An object identifier (OID) has a central utility in providing a traceable source for the meaning of an identifier appearing in a cross-system communication. The views in this paper illustrate the problems with using the present OID registration system as a reliable source for the identifier, the confusion that the use of an OID introduces in messages, and the redundancy that the OID introduces at the expense of increased message size and no new content. In promoting clearly defined cross-system communication identifiers, Health Level 7 developed a standard that required use of OIDs outside of network addressing. This standard and its propagation by others may have paradoxically added more confusion than clarity.

Background: Youth involved in the legal system have disproportionately higher rates of problematic substance use than non-involved youth. Identifying and connecting legal-involved youth to substance use intervention is critical and relies on the connection between legal and behavioral health agencies, which may be facilitated by learning health systems (LHS). We analyzed the impact of an LHS intervention on youth legal and behavioral health personnel ratings of their cross-system collaboration.

Background: Collaboration strategies refer to policies and practices used to align operations and services across organizations or systems. These strategies can influence implementation of cross-system interventions focused on improving integration of care, but remain under-specified and under-examined. This study identifies collaboration strategies and the conditions under which they affected implementation of Sobriety Treatment and Recovery Teams (START), an evidence-based intervention focused on integrating child welfare and behavioral health services for families involved with both systems.

  • The study investigates coordination issues in lung cancer screening (LCS) between Veterans Affairs (VA) and non-VA healthcare settings.
  • Data was gathered through interviews with healthcare providers at six VA medical centers, revealing challenges in managing referrals and tracking patients screened outside of VA.
  • The findings highlight that while non-VA options expand access, poor communication and unclear processes can lead to delays in cancer evaluations, signaling a need for improved coordination strategies to ensure quality care for Veterans.

Background: Leveraging electronic health record (EHR) data for clinical or research purposes heavily depends on data fitness. However, there is a lack of standardized frameworks to evaluate EHR data suitability, leading to inconsistent quality in data use projects (DUPs). This research focuses on the Medical Informatics for Research and Care in University Medicine (MIRACUM) Data Integration Centers (DICs) and examines empirical practices on assessing and automating the fitness-for-purpose of clinical data in German DIC settings.
