Toward ensuring care quality and safety across settings: examining time pressure in a nursing home with observational time motion study metrics based on the Omaha system.

BACKGROUND: Meaningful data to determine safe and efficient nursing workload are needed. Reasoning a nurse can accomplish a finite number of interventions and location changes per hour, examination of time pressure using time motion study (TMS) methods will provide a comparable indication of safe and efficient workload for an individual nurse. METHODS: An observer shadowed 11 nurses at a 250-bed nursing home in the Southeastern United States and recorded 160 h of observations using TimeCaT, web-based TMS data recording software. Predefined Omaha System nursing interventions (N = 57) and locations (N = 8) were embedded within TimeCaT. The time-stamped data were downloaded from TimeCaT and analyzed using descriptive and inferential statistics. Five time pressure metrics were derived from previous TMS findings in acute care settings. RESULTS: Overall, nurses spent 66 s for each intervention, performed 65 interventions per hour, stayed 130 s at each location, changed locations 28 times per hour, and multitasked for 29% of working time. Computed hourly time pressure metrics enabled visualization of variability in time pressure metrics over time, with differences in multitasking by licensure, unit/role, and observation session time. CONCLUSIONS: Nursing home nurses consistently experienced a high degree of time pressure, especially multitasking for one-third of their working time. To inform staffing decision making and improve the quality of care, resident outcomes, and nurse satisfaction, it is critical to identify ways to mitigate time pressure. Additional research is needed to refine and extend the use of the time pressure metrics.

Modeling Psychological Functioning in Refugees.

BACKGROUND: Refugee trauma survivors often experience posttraumatic stress disorder, other anxiety disorders, depression, and somatization. As a result, many suffer a disproportionate vulnerability to a variety of interpersonal, health, and social problems. OBJECTIVE: The study purpose was to develop a preliminary predictive model identifying high-risk refugee trauma survivors based on levels of trauma and psychological functioning. METHOD: A subset of 449 Somali and Oromo refugee trauma survivors was randomly selected from a larger study for secondary data analysis. Data from the PTSD Checklist-Civilian version, the Revised Hopkins Symptom Checklist, and the Sheehan Disability Inventory contributed to a psychological functioning score. A researcher-developed survey contributed to a composite trauma score. RESULTS: Predictors associated with functioning level differed by gender. Of interest, caring for children and increasing coping strategies were related to lower functioning in women. The regression relationship between trauma and functioning was linear in men but quadratic in women. CONCLUSION: Understanding the mechanisms linking trauma and function is implicated in the assessment of risk among trauma survivors. Predictive models inform the effective psychosocial interventions targeting those at greatest risk.
