- ItemDevelopment of a prototype personal digital assistant-decision support system for the management of adult obesity.(2007-09-03) Lee, Nam-Ju; Bakken, SuzanneOBJECTIVE The purpose of this study was to develop a prototype personal digital assistant decision support system PDA DSS based on a clinical practice guideline CPG for the management of obesity DESIGN The study was composed of four phases 1 analysis of advanced practice nurse APN students documentation related to the management of obesity using the Clinical Log APN CL APN 2 identification of functional requirements and data modeling through use case analysis and unified modeling language UML 3 evaluation of representation of obesity related concepts with standardized terminologies and 4 design of a web based prototype user interface RESULTS The analysis revealed the documentation rate of obesity as an assessment diagnosis and adherence to the CPG for obesity was low Through use case analysis and UML modeling the functional requirements screening assessment and documentation of CPG based obesity treatment plan were identified and a data model was built Overall the standardized terminologies that are used in the database for the CL APN could represent about 80 of the obesity related concepts However the terms of these standardized terminologies were not specific enough to represent all the concepts The systematized nomenclature of medicine clinical terms SNOMED CT could represent 83 of the concepts and was used to extend the knowledge base Based on the functional requirements specification four prototype screens were designed CONCLUSION The PDA DSS for the management of obesity has potential uses for education nursing practice and research As an educational tool it can be used to improve APN students adherence to the CPG s recommendations and to enhance informatics competencies The PDA DSS has the potential to improve APN students clinical decision making at the point of care and delivery of CPG based care thereby improving patients outcomes related to the management of obesity A randomized trial is underway to investigate the PDA DSS s impact on APN students screening rates and adherence to obesity CPG recommendations and users acceptance of the system

- ItemThe effect of a mobile clinical decision support system on the diagnosis of obesity and overweight in acute and primary care encounters.(2009-08-26) Lee, Nam-Ju; Chen, Elizabeth S; Currie, Leanne M; Donovan, Mary; Hall, Elizabeth K; Jia, Haomiao; John, Rita Marie; Bakken, SuzanneThe purpose of the study was to compare the proportion of obesity related diagnoses in clinical encounters N 1874 documented by nurses using a personal digital assistant based log with and without obesity decision support features The experimental group encounters in the randomized controlled trial had significantly more P 000 obesity related diagnoses 11 3 than did the control group encounters 1 and a significantly lower false negative rate 24 5 vs 66 5 P 000 The study findings provide evidence that integration of a decision support feature that automatically calculates an obesity related diagnosis increases diagnoses and decreases missed diagnoses and suggest that such systems have the potential to improve the quality of obesity related care
- ItemFunctional requirements specification and data modeling for a PDA-based decision support system for the screening and management of obesity.(2007-01-22) Lee, Nam-Ju; John, Ritamarie; Bakken, SuzanneThe purposes of this study were to identify the functional requirements of and to build the data model for a PDA DSS Through Use Case Analysis and UML modeling seven Use Cases were documented and Use Case Diagrams Activity Diagrams and Sequence Diagrams related to the management of were developed
- ItemMobile decision support for advanced practice nurses.(2006-11-14) Bakken, Suzanne; Chen, Elizabeth; Choi, Jeeyae; Currie, Leanne M; Lee, Nam-Ju; Roberts, Wm Dan; Soupios, MichaelMobile Decision Support for Advanced Practice Nurses MODS APN is a PDA based decision support tool designed to assist APNs in the diagnosis and management of smoking cessation obesity and depression It is currently being tested in a randomized controlled trial RCT in a sample of APN students to determine the effect on adherence to clinical practice guideline CPG recommendations Tools such as MODS APN have the potential to increase CPG adherence enhance evidence based practice promote patient safety and in the long term improve patient outcomes
- ItemPDA-based informatics strategies for tobacco use screening and smoking cessation management: a case study.(2007-10-03) Bakken, Suzanne; Roberts, W Dan; Chen, Elizabeth; Dilone, Joann; Lee, Nam-Ju; Mendonca, Eneida; Markatou, MarianthiThe purpose of this case study is to describe three incremental personal digital PDA based informatics strategies aimed at improving screening for tobacco use and guideline based tobacco cessation management 1 PDA clinical log with tobacco cessation diagnoses and plan of care options 2 PDA decision support system and 3 PDA decision support system with infobuttons context specific links to the National Cancer Institute s Cancer Information Services tobacco cessation information These strategies were implemented within the context of an evidence based advanced practice nurse curriculum at the Columbia University School of Nursing
- ItemPredictors of depression screening rates of nurses receiving a personal digital assistant-based reminder to screen.(2010-07-09) Schnall, Rebecca; Currie, Leanne M; Jia, Haomiao; John, Rita Marie; Lee, Nam-Ju; Velez, Olivia; Bakken, SuzanneThe purpose of this study was to determine if race ethnicity payer type or nursing specialty affected depression screening rates in primary care settings in which nurses received a reminder to screen The sample comprised 4 160 encounters in which nurses enrolled in advanced practice training were prompted to screen for depression using the Patient Health Questionnaire PHQ 2 PHQ 9 integrated into a personal digital assistant based clinical decision support system for depression screening and management Nurses chose to screen in response to 52 5 of reminders Adjusted odds ratios showed that payer type and nurse specialty but not race ethnicity significantly predicted proportion of patients screened
- ItemPreliminary analysis for the development of a PDA-based decision support system for the screening and management of obesity.(2006-11-14) Lee, Nam-Ju; Bakken, SuzanneThis preliminary study toward the development of a Mobile Decision Support System for Advanced Practice Nursing MODS APN for the management of obesity compared APN students current electronic clinical log CL APN documentation to an obesity clinical practice guideline CPG and examined the extent to which concepts related to the screening and management of obesity could be represented with standardized terminologies The data that were documented by APN students with the CL APN were retrieved using the Structured Query Language SQL and were compared to the CPG using a scoring tool developed for this study Only 1 4 of the encounters had obesity as an assessment diagnosis and about 40 of those encounters did not have any plans of care related to the CPG s main treatment recommendations Fifty six concepts related to the screening and management of obesity were extracted from the CPG and were mapped to 36 terms using standardized terminologies
