From Competition to Collaboration: How a Multi-Firm Research Coalition Is Realizing Rigorous Facility Evaluation at Parkland Hospital.

This case study presents the process of developing a multi-entity Research Coalition to evaluate the new Parkland Hospital. The field of evidence-based design has made progress in systematically investigating relationships between healthcare facility design and a range of human outcomes. Yet healthcare facility evaluation is not typically included in the scope of building contracts. Lack of clear responsibility for evaluation and limited funding have been long-term barriers that the industry has yet to overcome. Firms engaged in design research at Parkland Hospital agreed with hospital representatives to collaborate on an integrated facility evaluation. Each participating entity contributed resources toward the effort. To formalize shared goals and priorities, the group developed a Research Coalition Charter. Goals included streamlining evaluation efforts to minimize burden on the hospital, leveraging multiple expertise areas to vet research aims and approaches, contributing knowledge to inform healthcare design, and innovating a model for multi-firm collaboration. The Coalition also developed guidelines for sharing data and disseminating research findings. To date, the Research Coalition has achieved key milestones including institutional review board exemption, data use and research collaboration agreements, and data collection. The research aims encompass patient and staff outcomes hypothesized to improve in the new facility. Both primary and secondary data are being analyzed to test the hypotheses. Publications of findings are forthcoming. Collaborative research among competitors may be a viable approach to realizing evaluation that is critical to learning for healthcare facility decision makers and design practitioners.

Safer chairs for elderly patients: design evaluation using electromyography and force measurement.

A vast majority of patient fall events in hospitals involve the elderly. In inpatient care settings, despite the risk of fall, patients are encouraged to leave their bed, move around their room, and sit on their chair to progress in their healing. Despite the vital role of patient chair design in improving recovery, few studies have examined the ergonomic requirements of safe patient chairs. This study examined the impact of manipulating horizontal and vertical positions of armrests in a test chair on required physical effort during Stand-to-Sit-to-Stand (St-Si-St) transitions among 15 elderly women. Physical effort was measured using: (1) surface electromyography (sEMG); (2) force measurement by load cells; (3) video recording. Findings showed non-linear patterns of change in required physical effort due to changes in armrests' height and distance. It was also found that minimum effort is associated with armrests higher and farther apart than those in typical patient chairs. Practitioner Summary: Safe chairs are essential for inpatient recovery, yet their ergonomic features are not investigated. Impact of changes in chair armrests on required physical effort was examined using electromyography, force measurement and video recording. Armrests higher and farther apart than those in typical patient chairs may be safer for elderly patients.

If I were a band-aid, where would I be? Researching the use and location of supplies on two patient units.

OBJECTIVE: The purpose of this study was to gain insight into the use and storage of supplies in the neonatal intensive care and women's health units of Parkland Hospital in Dallas, Texas. BACKGROUND: Construction of a new Parkland Hospital is underway, with completion of the 862-bed, 2.5-million square feet hospital in 2014. Leaders from the hospital and representatives from one of its major vendors collaborated on a research study to evaluate the hospital's current supply management system and develop criteria to create an improved system to be implemented at the new hospital. METHOD: Approach includes qualitative and quantitative methods, that is, written survey, researcher observations, focus groups, and evaluation of hospital supply reports. RESULTS: Approaching the ideal location of supplies can be best approached by defining a nurse's activity at the point of care. Determining an optimal supply management system must be approached by understanding the "what" of caregivers' activities and then determining the "where" of the supplies that support those activities. CONCLUSIONS: An ideal supply management system locates supplies as close as possible to the point of use, is organized by activity, and is standardized within and across units.

Factors impeding flexible inpatient unit design.

OBJECTIVE: To identify and examine factors extraneous to the design decision-making process that could impede the optimization of flexibility on inpatient units. BACKGROUND: A 2006 empirical study to identify domains of design decisions that affect flexibility on inpatient units found some indication in the context of the acuity-adaptable operational model that factors extraneous to the design process could have negatively influenced the successful implementation of the model. This raised questions regarding extraneous factors that might influence the successful optimization of flexibility. METHOD: An exploratory, qualitative method was adopted to examine the question. Stakeholders from five recently built acute care inpatient units participated in the study, which involved three types of data collection: (1) verbal protocol data from a gaming session; (2) in-depth semi-structured interviews; and (3) shadowing frontline personnel. Data collection was conducted between June 2009 and November 2010. RESULTS: The study revealed at least nine factors extraneous to the design process that have the potential to hinder the optimization of flexibility in four domains: (1) systemic; (2) cultural; (3) human; and (4) financial. CONCLUSIONS: Flexibility is critical to hospital operations in the new healthcare climate, where cost reduction constitutes a vital target. From this perspective, flexibility and efficiency strategies can be influenced by (1) return on investment, (2) communication, (3) culture change, and (4) problem definition. Extraneous factors identified in this study could also affect flexibility in other care settings; therefore, these findings may be viewed from the overall context of hospital design.

Creating healing intensive care unit environments: physical and psychological considerations in designing critical care areas.

A number of elements contribute to a healing ICU environment. The layout of a critical care unit helps create an environment that supports caregiving, which helps alleviate a host of work-related stresses. A quieter environment, one that includes family and friends, dotted with windows and natural light, creates a space that makes people feel balanced and reassured. A healing environment responds to the needs of all the people within a critical care unit-those who receive or give care and those who support patients and staff. Critical care units should be designed to focus on healing the body, the mind, and the senses. The design and policies of that department can be created in such a way to provide a sense of calm and balance. The physical environment has an impact on patient outcomes; the psychological environment can, too. A healing ICU environment will balance both. The authors discuss the ways in which architecture, interior design, and behavior contribute to a healing ICU environment.

Effects of age, step direction, and reaction condition on the ability to step quickly.

BACKGROUND: The ability to take a step quickly is important for balance maintenance during activities of daily living. The purpose of this study was to investigate the effects of age, reaction condition, and step direction on the ability to take a volitional step as fast as possible. METHODS: The performance of a voluntary step task was measured in young adult (mean age 20, SD 0.9 years), young-old adult (mean age 67, SD 3.7 years), and old adult (mean age 78, SD 2.3 years) healthy female participants. Each participant stepped as fast as possible in eight directions in response to a visual cue in a simple or choice reaction time condition. The effects of age, reaction condition, and step direction and their interactions on the primary outcome variables of response time, step liftoff, and step landing time were examined. RESULTS: The normal aging process progressively increased the response, liftoff, and landing times. The choice reaction time condition, compared to the simple, had significantly increased response, liftoff, and landing times. Step direction significantly affected the liftoff and landing times, with lateral, diagonal, and anterior and posterioir (A-P) times increasing, respectively. CONCLUSIONS: We found substantial declines in the ability to step rapidly in healthy adults as age increased. When a decision was required regarding the step direction, the step performance also declined. Step direction also significantly affected step performance. The assessment of voluntary step performance, which may be an indicator of balance ability, should include dimensions of both direction and the choice condition.
