1. Development of a Manually Operated Communication System (MOCS) for Patients in Intensive Care Units

Author

Goldberg, Miriam A., Hochberg, Leigh R., Carpenter, Dawn, and Walz, J. Matthias

Abstract

Nonvocal alert patients in the intensive care unit (ICU) setting often struggle to communicate due to inaccessible or unavailable tools for augmentative and alternative communication. Innovation of a hand-operated non-touchscreen communication system for nonvocal ICU patients was guided by design concepts including speech output, simplicity, and flexibility. A novel communication tool, the Manually Operated Communication System (MOCS), was developed for use in intensive care settings with patients unable to speak. MOCS is a speech-output technology designed for patients with manual dexterity impairments preventing legible writing. MOCS may have the potential to improve communication for nonvocal patients with limited manual dexterity.

18. Testing a Novel Manual Communication System for Mechanically Ventilated ICU Patients

Author

Goldberg, Miriam A., Hochberg, Leigh R., Carpenter, Dawn, Isenberger, Johnny L., Heard, Stephen O., and Walz, J. Matthias

Abstract

Introduction: Available communication methods for intubated patients in the ICU are insufficient to meet patient needs. Both ICU patients and their care providers report broadly unsuccessful communication attempts, resulting in less effective medical care and undue stress1,2. Use of existing methods - including letter boards, writing, and mouthing words - for mechanically ventilated (MV) patients has led to a consensus that new methods are required3. We report on the testing of a new system designed to address the communication needs of MV patients that is currently being tested in a low- to medium- acuity surgical ICU4. Methods: We have developed several generations of prototypes designed to address patient communication needs. Design of this device has focused on ICU-specific communication needs, including ICU-specific content, infection control, simple design, and capitalizing on motor movements that can be easily performed by most ICU patients. Initial testing, starting with non-MV patients able to give more detailed feedback, has begun in a low- to medium- acuity surgical ICU. Recently developed prototypes combine custom-built tablet software, focusing on the needs that nurses believe patients wish to express in the ICU setting, with a newly designed manually operated access device. The system produces visual and auditory output to allow patients to answer basic questions and effectively convey information. Results: Initial patient impressions are encouraging, particularly among patients who have recently experienced mechanical ventilation. Many patients are unfamiliar with tablet software or struggle with manual dexterity required to access the tablet screen directly, further indicating the need for an external access method as part of the system. The content suggested by nurses via a previously conducted survey has been confirmed by patients as relevant to their experience. Conclusions: A novel manually operated communication system has elicited both positive reviews and helpful feedback from patients.

Abstract

Introduction: CLABSI remains a significant problem in the intensive care unit. Hypothesis: A multimodal approach for the insertion and care of CVC will prevent CLABSI. Methods: A Critical Care Operations Committee was formed to transform care in 8 intensive care units (ICU) in an academic medical center in 9/2004. One goal was to reduce CLABSI. Using evidence based medicine, a clinical practice guideline was developed that incorporated the use of maximum barrier precautions, chlorhexidine skin preparation, avoidance of the femoral insertion site, dedicated catheter cart, a check list, the tracking of high risk CVC, anti-septic or antimicrobial impregnated catheters, a recommendation to use ultrasound guidance when inserting CVC in the internal jugular vein, daily determination of the need for the CVC and treatment of CLABSI as a critical event.CLABSI were adjudicated by the hospital epidemiologist and CVC days were tracked. Rates of CLABSI were followed from 9/2004 through 7/2011. The Spearman correlation coefficient was used for statistical evaluation. A p Results: CLABSI rates (per 1000 catheter-days) declined dramatically from 2004 to 2011 (p Conclusions: A multimodal approach to CVC insertion and care reduces CLABSI by over 90%. Our ultimate goal is the complete eradication of CRBSI in our institution.

Abstract

The article focuses on an analysis of endotracheal intubation (EEI) significance in an intensive care unit (ICU) services along with risks over its usage. Topics discussed include assessment of different issues related to an intubation usage such as hypoxemia; consideration of ramped position for patient while usage of EEI services in an operating room (OR); and analysis of arterial oxygen saturation conditions with performance of EEI through direct laryngoscopy (DL).
