Omaha System • Used in public health information systems and clinical documentation in the US and internationally. – Omaha System data fill a void in existing population data sources – Activities of public health clinicians: • Problems assessed • Interventions delivered • Outcomes observed
Omaha System Partership • Invited by Dean Delaney – Center of Nursing Informatics, University of Minnesota School of Nursing • Practice-based Research Network – Building scientific inquiry methods – Generating new knowledge • Over 50 studies in progress or completed
Omaha System Partnership • multidisciplinary scientific teams of researchers with experience in advanced data analysis and data mining techniques – University of Minnesota – University of Pennsylvania – Istanbul University
Omaha System Partnership • affiliate members from many countries who contribute clinical Omaha System data, suggest important clinical questions, and work together with the scientific team on research and evaluation projects
Omaha System Partnership • a warehouse of de-identified clinical Omaha System data including client problems, signs/symptoms, interventions, and knowledge, behavior, and status outcomes
Three Recent Studies • descriptive study of problems experienced by community dwelling adults with schizophrenia • comparative study of public health nursing services and outcomes for adult and adolescent Latina mothers • analysis of hearing assessments for firefighters
Community Dwelling Adults with Schizophrenia PI Elaine Darst Team: Students and Community Partners Data source: Interview Purpose: To evaluate the use of the Omaha System for assessment of community dwelling older adults with schizophrenia Method: Case Study
Results Description of complex client problems was facilitated by use of the Omaha System Comprehensive Holistic Standardized
Problems identified Income Neighborhood/workplace safety Abuse Physical activity Mental health Cognition Nutrition Substance use
Areas of Greatest Concern Mental health Cognition Nutrition Substance use
Mental health assessment K 2 Some knowledge of symptoms of his mental illness; poor knowledge of impact of illness symptoms on life; minimal understanding of positive coping skills. B 4 Med-compliant due to supportive environment. Regularly accesses mental health care under supervision of staff. S 2 Symptoms of mental illness severe enough to warrant a 24 -hour care setting; vacillating levels of anxiety, depression, agitation and psychosis.
Structured Living Situation Contributes to Patient Stability KBS ratings show differences in dimensions of functioning Differences may indicate level of probable patient functioning without support Future research: develop algorithm to assess risk of decompensation using KBS ratings
Comparison of PHN outcomes for adolescent and adult mothers with and without the Mental health problem • PI: Carolyn Garcia • Team: U of M, Rush University • Data source: Large metropolitan public health nursing agency • Purpose: to determine effectiveness of PHN visits for improving outcomes in Latina adolescents with mental health problems
Background • Health Literacy study – Knowledge scores across problems by race/ethnicity – Optimal response to PHN interventions among Latinas – Mental health is a concern for all Benchmark = 3
Method • Design: Nested-block, pre-test and post-test. • Blocking factors include age of the client and mental health problem. • General linear mixed models adjusted for number of problems, length of service and the number of visits. • Outcomes were expressed as a change in Knowledge, Behavior and Status scores.
Knowledge • KBS scores improved after PHN services (p < 0. 001). • Knowledge improved equally for all groups.
Behavior • Behavior improved most for adult clients with mental health problems (p = 0. 013).
Status • Status showed the greatest statistical improvement for adolescents with mental health problems (p = 0. 012).
Status • An increase in the number of PHN visits was related to an increased status change in adolescents with mental health problems (p = 0. 011). • Status change was attenuated for clients with increasing number of problems (p < 0. 001).
Firefighter Hearing PI: Oi. Saeng Hong Team: UCSF, Uof. M Data source: Large research data set Purpose: to model hearing health outcomes of a health promotion intervention using Knowledge, Behavior, and Status scores o Method: correlation following data transformation o o
Background o Occupational noise-induced hearing loss is one of the most prevalent occupational injuries in the U. S. yet there are limited data on hearing ability of workers. Data are needed to describe the extent of NIHL and to measure outcomes of hearing loss prevention programs. o New data standards and electronic health record (EHR) systems offer technology solutions to inform the information gap.
Knowledge o Knowledge: the ability of the client to remember and interpret information. (1=no knowledge - 5=superior knowledge) o Knowledge algorithm n responses to four noise-induced hearing loss questions n 1=0 correct; 2=1 correct; 3=2 correct; 4=3 correct; and 5=4 correct responses o The mean score was close to adequate for knowledge (3. 72). n About 75% of participants correctly answered all four items of knowledge.
Behavior o Behavior: observable responses, actions, or activities of the client fitting the occasion or purpose. (1=not appropriate 5=consistently appropriate) o Behavior algorithm n frequency of self-reported percentage of time of HPD use during loud noise exposure n 1= 0 -20%; 2=21 -40%; 3=41 -60%; 4=61 -80%; and 5=81 -100% o The mean score was close to minimally acceptable for behavior (2. 22) n Only 12% consistently used appropriate hearing protection devices more than 80% of the time that they were needed.
Status o Status: the Condition of the client in relation to objective and subjective defining characteristics (1=extreme signs & symptoms 5=no signs & symptoms) o Status algorithm n grading system proposed by the World Health Organization (1986) n 1>80 d. B; 2=61 -80 d. B; 3=41 -60 d. B; 4=25 -40 d. B; and 5<25 d. B o The mean score for status was minimal signs and symptoms (4. 39)
Bivariate correlations among three KBS variables o Significant positive relationship between knowledge and behavior (Spearman’s rho=. 13, p=. 01), and Behavior and status (Spearman’s rho=. 12, p=. 02). o There was no significant relationship between knowledge and status.
Realizing the Goal • Use of a shared interface terminology enables large-scale population health research across settings, populations, practices, languages, and countries
Working Together in Partnership • Practice-based research partnerships are an optimal environment in which to enhance practice, evaluate programs, measure outcomes, and improve population health.
