Creation of a gold standard for validation of a computer-interpretable depression screening guideline.

Clinical practice guidelines (CPGs) are common tools for clinicians in daily practice. In order to use CPGs effectively at the point of care, representing CPGs into computer-interpretable format is essential. Since computer-interpretable guidelines (CIGs) have been reported to increase clinicians' usage of guidelines and improve patient's outcomes, it is critical to validate health care knowledge translated from CPGs into CIGs. A comprehensive method of developing and evaluating a gold standard for a depression screening CIG was performed and analyzed in this study. GLIF encoding was conducted for a depression screening CPG and 21 clinical scenarios were created based on the encoded depression screening CIG. Two nurse practitioners were recruited to generate initial management for each scenario. Proficiency and efficiency scores were calculated for each scenario. In 13 of 21 scenarios, both experts had proficiency scores of 100%. Proficiency scores were lowest for scenarios that included bipolar disease. Implications of our findings for development of a gold standard are discussed.

Usefulness of a personal digital assistant-based advanced practice nursing student clinical log: Faculty stakeholder exemplars.

The number of health sciences educational programs that are integrating personal digital assistants (PDAs) into their curricula is on the rise. In this paper, we report an evaluation of the usefulness of a PDA-based advanced practice nursing (APN) student clinical log through faculty stakeholder exemplars in three areas: pediatric asthma care; procedures of Acute Care Nurse Practitioner (NP) students; and diagnostic and screening procedures of Women's Health NP students. We generated descriptive data through routine queries and through custom SQL queries at the request of a specific faculty member who wished to examine a particular aspect of an educational program. In addition, we discussed the potential implications of the data with the respective faculty members. The exemplars provide evidence that faculty stakeholders found the APN student clinical log to be useful for a variety of purposes including monitoring of student performance, benchmarking, and quality of care assessments.

Encoding a depression screening guideline using GLIF.

Computer-interpretable guidelines (CIGs) have been reported to increase clinicians' usage of guidelines and to improve patient outcomes. The Guideline Interchange Format (GLIF) represents a guideline as a flowchart of clinical decision and action steps. We encoded a depression screening guideline using GLIF to transform it into a CIG. After identifying all guideline steps from the text format guideline, a flowchart was drawn using the encoded steps in GLIF. The flowchart was validated by an experienced psychiatric nurse clinician.

Mobile decision support for advanced practice nurses.

Mobile 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.

Adapting current Arden Syntax knowledge for an object oriented event monitor.

Arden Syntax for Medical Logic Module (MLM)1 was designed for writing and sharing task-specific health knowledge in 1989. Several researchers have developed frameworks to improve the sharability and adaptability of Arden Syntax MLMs, an issue known as "curly braces" problem. Karadimas et al proposed an Arden Syntax MLM-based decision support system that uses an object oriented model and the dynamic linking features of the Java platform.2 Peleg et al proposed creating a Guideline Expression Language (GEL) based on Arden Syntax's logic grammar.3 The New York Presbyterian Hospital (NYPH) has a collection of about 200 MLMs. In a process of adapting the current MLMs for an object-oriented event monitor, we identified two problems that may influence the "curly braces" one: (1) the query expressions within the curly braces of Arden Syntax used in our institution are cryptic to the physicians, institutional dependent and written ineffectively (unpublished results), and (2) the events are coded individually within a curly braces, resulting sometimes in a large number of events - up to 200.

Effect of aromatherapy on symptoms of dysmenorrhea in college students: A randomized placebo-controlled clinical trial.

OBJECTIVE: The purpose of this study was to explore the effect of aromatherapy on menstrual cramps and symptoms of dysmenorrhea. DESIGN: The study was a randomized placebo-controlled trial. SUBJECTS: The subjects were 67 female college students who rated their menstrual cramps to be greater than 6 on a 10-point visual analogue scale, who had no systemic or reproductive diseases, and who did not use contraceptive drugs. INTERVENTION: Subjects were randomized into three groups: (1) an experimental group (n = 25) who received aromatherapy, (2) a placebo group (n = 20), and (3) a control group (n = 22). Aromatherapy was applied topically to the experimental group in the form of an abdominal massage using two drops of lavender (Lavandula officinalis), one drop of clary sage (Salvia sclarea), and one drop of rose (Rosa centifolia) in 5 cc of almond oil. The placebo group received the same treatment but with almond oil only, and the control group received no treatment. OUTCOME MEASURES: The menstrual cramps levels was assessed using a visual analogue scale and severity of dysmenorrhea was measured with a verbal multidimensional scoring system. RESULTS: The menstrual cramps were significantly lowered in the aromatherapy group than in the other two groups at both post-test time points (first and second day of menstruation after treatment). From the multiple regression aromatherapy was found to be associated with the changes in menstrual cramp levels (first day: Beta = -2.48, 95% CI: -3.68 to -1.29, p < 0.001; second day: Beta = -1.97, 95% CI: -3.66 to -0.29, p = 0.02 and the severity of dysmenorrhea (first day: Beta = 0.31, 95% CI: 0.05 to 0.57, p = 0.02; second day: Beta = 0.33, 95% CI: 0.10 to 0.56, p = 0.006) than that found in the other two groups. CONCLUSIONS: These findings suggest that aromatherapy using topically applied lavender, clary sage, and rose is effective in decreasing the severity of menstrual cramps. Aromatherapy can be offered as part of the nursing care to women experiencing menstrual cramps or dysmenorrhea.

Improving the human readability of Arden Syntax medical logic modules using a concept-oriented terminology and object-oriented programming expressions.

Medical logic modules are a procedural representation for sharing task-specific knowledge for decision support systems. Based on the premise that clinicians may perceive object-oriented expressions as easier to read than procedural rules in Arden Syntax-based medical logic modules, we developed a method for improving the readability of medical logic modules. Two approaches were applied: exploiting the concept-oriented features of the Medical Entities Dictionary and building an executable Java program to replace Arden Syntax procedural expressions. The usability evaluation showed that 66% of participants successfully mapped all Arden Syntax rules to Java methods. These findings suggest that these approaches can play an essential role in the creation of human readable medical logic modules and can potentially increase the number of clinical experts who are able to participate in the creation of medical logic modules. Although our approaches are broadly applicable, we specifically discuss the relevance to concept-oriented nursing terminologies and automated processing of task-specific nursing knowledge.
