Evaluation of Validity and Reliability of a Revised Incontinence-Associated Skin Damage Severity Instrument (IASD.D.2) by 3 Groups of Nursing Staff.

PURPOSE: The purpose of this study was to evaluate a revised version of the Incontinence-Associated Skin Damage Severity instrument (IASD.D.2) using 3 different groups of nursing staff. Revisions to the instrument included renumbering 1 body area where incontinence-associated dermatitis (IAD) occurs into 2 areas (right and left), which raised the total possible score from 52 to 56, and defining the borders of the body areas. DESIGN: Observational, evaluative design. SAMPLE AND SETTING: Five clinical experts certified in wound, ostomy, and/or continence (WOC) nursing evaluated content validity. Evaluators were attendees at the WOC Nurses (WOCN) Society 2014 conference, hospital nurses, and nursing staff at a nursing home. Evaluators were attendees at the WOCN Society's 2014 National Conference, hospital nurses at a community hospital with Magnet designation, and nursing staff at a skilled nursing home in the Midwestern United States. The evaluator group comprised 198 conference attendees (all nurses; age 53 ± 8.2 years, mean ± SD), 67 hospital nurses (age 37 ± 11 years), and 34 nursing home nursing staff (age 45 ±13.8 years). The majority of evaluators (>75%) in each of the groups were female. METHODS: Clinical experts evaluated the content validity of the revised instrument. Evaluators scored 5 to 9 photographic cases using the revised instrument. Four of the cases were scored by all evaluators. The agreement of case scores among all evaluators was analyzed to assess interrater reliability. The scores of evaluators grouped by evaluators' self-identified skin color or nursing experience (<10 years vs ≥10 years) were also tested for differences. To provide evidence for criterion validity, the agreement of evaluators' scores with experts' scores (considered a "gold standard" in this study) was analyzed. RESULTS: The agreement of the IASD.D.2 scores among all evaluators within each group ranged from 0.74 to 0.79, suggesting good interrater reliability. The agreement of each group of evaluators with the experts for all case scores ranged from 0.82 to 0.85, suggesting good criterion validity. There was no significant difference in scores by evaluators' skin color or nursing experience. CONCLUSION: The revised IASD.D.2 has good content and criterion validity and interrater reliability. The instrument has potential to standardize reporting of IAD severity in research and clinical practice and assist communication about IAD among nursing staff.

Medical Device-Related Pressure Injuries in Long-term Acute Care Hospital Setting.

PURPOSE: The purpose of this study was to examine the epidemiology of medical device-related pressure injuries (MDRPIs) in 3 long-term acute care hospitals (LTACHs). DESIGN: Retrospective descriptive study. SUBJECTS AND SETTING: The sample comprised 304 adult inpatients at 3 geographically diverse LTACHs: Spaulding Hospital for Continued Medical Care, Drake Center, and Bethesda Hospital. The facilities are located in the Northeastern, Southeastern, and Midwestern United States. METHODS: Hospital-acquired pressure injury (HAPI) data and MDRPI data were collected and reported for the 3 LTACHs from July 1, 2009, to June 30, 2010. Data were collected by the wound nurses at 2 of the facilities on a daily or weekly basis and quarterly at the remaining site. RESULTS: One hundred forty-two MDRPIs occurred during data collection, representing an occurrence rate of (47%). The proportion of MDRPIs and HAPIs at each of the LTACHs was 38%, 50%, and 47%, respectively. The most commonly reported medical devices causing pressure injury were respiratory devices, splints and braces, and tubing. CONCLUSIONS: The MDRPI rate identified in the LTACH setting was higher than rates reported in the literature. This study's findings confirm the importance of monitoring MDRPIs in order to implement appropriate prevention strategies.

Refinement of an instrument for assessing incontinent-associated dermatitis and its severity for use with darker-toned skin.

PURPOSE: The purpose of this study was to refine an instrument for assessing incontinence-associated dermatitis (IAD) and its severity for use on lighter- and darker-toned skin, the Incontinence-Associated Dermatitis and its Severity Instrument-D (IADS-D), and to test its validity and reliability among WOC nurses. METHODS: Revisions to the existing instrument included examples of colors of normal and IAD-damaged skin that would be observed on light-, medium-, and dark-toned skin using pixels from patient photographs, additional photographs of IAD manifestations on different skin tones, and training materials. Four certified WOC nurse consultants and 2 WOC nurse clinical experts assessed the face and content validity of the IADS-D instrument. The IADS-D instrument was tested for criterion validity and interrater reliability using photo cases by attendees at the Wound, Ostomy, and Continence Nurses Society 2012 conference. RESULTS: The IADS-D instrument had good face and content validity. The overall average intraclass correlation coefficient (ICC) of IADS-D scores for all photo cases of testers (n = 266, 95% female, age 53.0 ± 7.9 years, mean ± SD) and those of investigators, experts, and consultants serving as the criterion was 0.90. The overall ICC for interrater reliability between all nurse testers was 0.99 and the ICC for tester skin tone was 0.99. CONCLUSION: The IADS-D instrument has excellent validity and interrater reliability among WOC nurses. Its refinement for use with lighter- and darker-toned skin addresses the lack of a much-needed instrument in nursing practice and research. Results support continued development and evaluation of the instrument's use in clinical and research settings.

The incontinence-associated dermatitis and its severity instrument: development and validation.

PURPOSE: To develop and test the validity and interrater reliability of the Incontinence-Associated Dermatitis and its Severity Instrument, a novel tool describing incontinence-associated dermatitis and its severity. METHODS: Investigators consulted 2 certified WOC nurse experts to determine face validity of the instrument. Seven additional certified WOC nurses evaluated the tool for content validity. The instrument was tested for interrater reliability by attendees at the 2007 WOCN Society National Conference and employees at a health care system in Minnesota. Criterion validity was determined by comparing IAD severity scores of testers with those of the 2 WOC experts and PI. RESULTS: Consultants determined that the instrument had face and content validity. Two hundred forty-seven attendees at the WOCN Society's National Conference (mean nursing experience 25±9 years [mean±SD]), 100 nursing staff in Minnesota: 84 staff nurses (mean nursing experience 17±12 years), and 16 nursing assistants (mean nursing experience 7±7 years) determined that the instrument has content validity. There were no significant differences in scores of IAD severity for the 4 cases among the 3 types of testers (P>.05). Overall agreement between the 347 raters and the experts using intraclass correlation was 0.98 (P=.006). CONCLUSION: The Incontinence-Associated Dermatitis and its Severity Instrument demonstrated good validity and interrater reliability and its development fulfills an unmet need in both research and clinical practice settings.
