    Examining facilitators for men during nursing education: development and psychometric testing of the survey of facilitators for men (SFM)
    (2015) Clark-Ott, Dorothy G.; Bakas, Tamilyn; Ellett, Marsha; Horton-Deutsch, Sara L.; Pesut, Daniel J.
    Despite outstanding employment opportunities and high demand to address the global nursing shortage, men who consider becoming nurses are less likely to enroll in and to graduate from nursing programs. Many barriers that men commonly encounter during nursing education have been found in the literature; however, there is a lack of theoretically based research that examines factors that help men succeed as they study nursing. Based on a conceptual model derived from O’Lynn’s construct of male friendliness in nursing education and Frankl’s theory of will to meaning and purpose in life, this study examined facilitators for men during nursing education. This was accomplished through the development and psychometric testing of the Survey of Facilitators for Men (SFM) in a sample of 145 men in nursing. Strong evidence of reliability and validity was provided for the SFM consisting of three subscales (Internal facilitators, External Connections facilitators, and Institutional facilitators). Internal facilitators consist of intrapersonal strengths, experiences, and motivators. External Connections facilitators are interpersonal connections that emerge from relationships that men develop. Institutional facilitators involve structural or organizational aspects of institutions that ease barriers. Testing provided satisfactory evidence of internal consistency (α = .85) and test-retest reliability (intraclass coefficient = .72; confidence interval = 0.57–0.83). Dimensionality of three facilitator subscales was supported by Principle Axis Factoring with Varimax rotation and satisfactory factor loadings (.49–.72). Support for the conceptual model was provided using multiple regressions explaining 17% of the variance in purpose in life [F(4, 140) = 6.99, p < .001], 13% of the variance in GPA [F(6, 114) = 2.88, p < .01], and 49% of the variance in perception of nursing success [F(9, 128) = 13.42, p < .001]. Purpose in life was associated with Internal facilitators and comfortable income, GPA was associated with External Connections facilitators and age at BSN, while perception of nursing success was associated with purpose in life, holding an MSN, having a comfortable income, and having children. Future research is warranted to determine the usefulness of the SFM in designing strategies to recruit and retain men in nursing programs.

    In vitro comparison of gastric aspirate methods and feeding tube properties on the quantity and reliability of obtained aspirate volume
    (2013-11-20) Bartlett Ellis, Rebecca J.; Ellett, Marsha; Bakas, Tamilyn; Beckstrand, Janis; Fuehne, Joseph; Lu, Yvonne
    Gastric residual volume (GRV) is a clinical assessment to evaluate gastric emptying and enteral feeding tolerance. Factors such as the tube size, tube material, tube port configuration, placement of the tube in the gastric fluid, the amount of fluid and person completing the assessment may influence the accuracy of residual volume assessment. Little attention has been paid to assessing the accuracy of GRV measurement when the actual volume being aspirated is known, and no studies have compared the accuracy in obtaining RV using the three different techniques reported in the literature that are used to obtain aspirate in practice (syringe, suction, and gravity drainage). This in vitro study evaluated three different methods for aspirating feeding formula through two different tube sizes (10 Fr [small] and 18 Fr [large]), tube materials (polyvinyl chloride and polyurethane), using four levels of nursing experience (student, novice, experienced and expert) blinded to the five fixed fluid volumes of feeding formula in a simulated stomach, to determine if the RV can be accurately obtained. The study design consisted of a 3x2x2x4x5 completely randomized factorial ANOVA (with a total of 240 cells) and 479 RV assessments were made by the four nurse participants. All three methods (syringe, suction and gravity) used to aspirate RV did not perform substantially well in aspirating fluid, and on average, the methods were able to aspirate about 50% of the volume available. The syringe and suction techniques were comparable and produced higher proportions of RVs, although the interrater reliability of RV assessment was better with the syringe method. The gravity technique generally performed poorly. Overall, the polyvinyl chloride material and smaller tubes were associated with higher RV assessments. RV assessment is a variable assessment and the three methods did not perform well in this in vitro study. These findings should be further explored and confirmed using larger samples. This knowledge will be important in establishing the best technique for assessing RV to maximize EN delivery in practice and will contribute to future research to test strategies to optimize EN intake in critically ill patients.

    OSTOMY COMPLICATIONS AND ASSOCIATED RISK FACTORS: DEVELOPMENT AND TESTING OF TWO INSTRUMENTS
    (2011-08-23) Pittman, Joyce A.; Rawl, Susan M.; Bakas, Tamilyn; Ellett, Marsha; Sloan, Rebecca S.
    Complications following intestinal ostomy surgery can diminish quality of life for individuals living with an ostomy, resulting in physical and psychosocial limitations. Risk factors contributing to ostomy complications are not well established in the literature. The purposes of this study were to: 1) identify risk factors contributing to the development of fecal ostomy complications; 2) describe the incidence and severity of early fecal ostomy complications; and 3) estimate the reliability and validity of two newly developed instruments, Ostomy Risk Factor Index (ORFI) and Ostomy Complication Severity Index (OCSI). Using a prospective longitudinal design, 71 adult patients who had undergone ostomy surgery were recruited from three acute care settings. Data were collected through self-administered surveys, medical record review, and direct observation prior to discharge and at 30 to 60 days post-operatively. Data were analyzed using descriptive statistics, analysis of variance, chi-square tests, correlation, and multiple regression. Psychometric properties of the Ostomy Risk Factor Index and the Ostomy Complication Severity Index were examined using content validity indices, Cohen coefficient kappa, Pearson correlation coefficient, and intra-class correlation. Two risk factors were found to be predictive of ostomy complications scores, stoma/abdomen characteristics (p= .007) and BMI (p= .002). Ostomy complications and ostomy adjustment were significantly inversely correlated (r= - 0.27, p=.04) and stoma care self-efficacy and ostomy adjustment were significantly correlated (r= .599, p= .01). The ORFI and OCSI demonstrated acceptable content validity (CVI= 0.9). ORFI demonstrated acceptable inter-rater reliability for 10 of the 14 items (k= 1.0) and excellent intraclass correlation of total scores between raters (r= .998, p= .001). The OCSI demonstrated acceptable inter-rater reliability for all of the items (k= .71- 1.0) and excellent intra-class vii correlation of total scores between raters (r= .991, p= .000). The OCSI demonstrated acceptable internal consistency (Cronbach's alpha .68). In conclusion, this study provides new knowledge regarding risk factors, incidence and severity of ostomy complications, and provided support for the validity and reliability of two new instruments for the researcher and practitioner to reliably identify and describe important contributors (risk factors) and outcomes (complications) that affect care of the patient with an ostomy.

    Psychometric evaluation of the ostomy complication severity index
    (Journal of Wound, Ostomy and Continence Nursing, 2014-03) Pittman, Joyce; Bakas, Tamilyn; Ellett, Marsha; Sloan, Rebecca; Rawl, Susan M.
    PURPOSE: The purpose of this study was to evaluate the psychometric properties of a new instrument to measure incidence and severity of ostomy complications early in the postoperative period. SUBJECTS AND SETTINGS: 71 participants were enrolled, most were men (52%), white (96%), and married or partnered (55%). The mean age of participants was 57 ± 15.09 years (mean ± SD). Fifty-two participants (84%) experienced at least 1 ostomy complication in the 60-day postoperative period. The research setting was 3 acute care settings within a large healthcare system in the Midwestern United States. INSTRUMENT: We developed an evidence-based conceptual model to guide development and evaluation of a new instrument, the Pittman Ostomy Complication Severity Index (OCSI). The OCSI format includes Likert-like scale with 9 individual items scored 0 to 3 and a total score computed by summing the individual items. Higher scores indicate more severe ostomy complications. METHOD: This study consisted of 2 phases: (1) an expert review, conducted to establish content validity; and (2) a prospective, longitudinal study design, to examine psychometric properties of the instrument. A convenience sample of 71 adult patients who underwent surgery to create a new fecal ostomy was recruited from 3 hospitals. Descriptive analyses, content validity indices, interrater reliability testing, and construct validity testing were employed. RESULTS: Common complications included leakage (60%), peristomal moisture-associated dermatitis (50%), stomal pain (42%), retraction (39%), and bleeding (32%). The OCSI demonstrated acceptable evidence of content validity index (CVI = 0.9) and interrater reliability for individual items (k = 0.71-1.0), as well as almost perfect agreement for total scores among raters (ICC = 0.991, P = .001). Construct validity of the OCSI was supported by significant correlations among variables in the conceptual model (complications, risk factors, stoma care self-efficacy, and ostomy adjustment). CONCLUSION: OCSI demonstrated acceptable validity and reliability and can be used to assess incidence and severity of ostomy complications in the early postoperative period. We found the OCSI to be brief, easy-to-use, and clinically practical. It can be used to (a) identify priority areas for nursing intervention related to the ostomy, (b) determine appropriate interventions to prevent or treat complications, and (c) evaluate the effects of nursing interventions designed to improve outcomes for patients with ostomies.
