我使用基於the one found in this answer的PHP類來解析5個RSS提要。五項工作中的四項沒有任何問題，但one of them給了我一些錯誤。它是XML格式錯誤還是其他一些問題？我無法控制RSS源的來源，但希望在問題是他們的時候通知主人。PHP錯誤解析XML（RSS提要）
在此先感謝。

<description>Mobile devices have pervaded the everyday work environment in healthcare. An organization may use mobile devices to improve clinician workflow, bedside information gathering and reporting, or a host of other care delivery applications. In some cases, individuals may use their own mobile devices to meet their personal workflow requirements.
Whatever purpose the device serves, healthcare organizations must be prepared to understand all the issues related to mobile device use.
This practice brief reviews the legal and regulatory requirements that affect mobile device use in healthcare. It also provides best practices for ensuring appropriate safeguards are in place to protect all electronic protected health information (ePHI) used and processed within mobile devices.</description>

<title>Workflow and EHRs in Small Medical Practices </title>
<pubDate>4/13/2012 2:45:16 PM</pubDate>
<link>http://perspectives.ahima.org/index.php?option=com_content&view=article&id=247:workflow-and-electronic-health-records-in-small-medical-practices&catid=42:electronic-records&Itemid=88</link>

<description>This paper analyzes the workflow and implementation of electronic health record (EHR) systems across different functions in small physician offices. We characterize the differences in the offices based on the levels of computerization in terms of workflow, sources of time delay, and barriers to using EHR systems to support the entire workflow.
The study was based on a combination of questionnaires, interviews, in situ observations, and data collection efforts. This study was not intended to be a full-scale time-and-motion study with precise measurements but was intended to provide an overview of the potential sources of delays while performing office tasks. The study follows an interpretive model of case studies rather than a large-sample statistical survey of practices. To identify time-consuming tasks, workflow maps were created based on the aggregated data from the offices. The results from the study show that specialty physicians are more favorable toward adopting EHR systems than primary care physicians are. The barriers to adoption of EHR systems by primary care physicians can be attributed to the complex workflows that exist in primary care physician offices, leading to nonstandardized workflow structures and practices. Also, primary care physicians would benefit more from EHR systems if the systems could interact with external entities.

<description>For the HIM profession to remain relevant and influential we must have a dynamic and expanding knowledge base and defined set of desired skills and expertise.
To remain relevant we need to expand our knowledge base and stakeout our content area of expertise through mission and discipline critical research. This research must meet standards of scientific rigor and set the foundation for knowledge creation, innovative concept development, and thought leadership.
To increase influence we need to disseminate knowledge through scholarly processes and publications that inform best practices and influence policy makers. Scholarship must demonstrate our unique expertise and content knowledge base within the healthcare industry. Furthermore, knowledge transfer or dissemination will increase AHIMA brand recognition and enhance brand prestige and prominence.
To sustain a systematic research initiative AHIMA has established a centralized, high performing Research Innovation and Leadership Institute (RILI) as an enduring mission critical component of the AHIMA Foundation.
