Patient-Focused Care: A Healthy, Healing Environment for Recovery

Critical Care Unit (CCU) design is evolving to meet the demands of modern healthcare, focusing on flexibility, patient-centered care, clinical efficiency, and technological integration. Through the lens of our client, this article explores key considerations and design influencers, non-negotiables, clinicians and administrative stakeholder involvement, and metrics used to evaluate performance against the original project charter.

In designing the new Critical Care Unit (CCU) for a midwestern healthcare client, decisions were made with thoughtfulness toward patient well-being and staff satisfaction. From the layout of the rooms to the size and shape of windows, this unit was designed to enhance patient care and healing as well as staff efficiency and safety.

Safety & Infection Control

As part of the patient care experience, minimizing stress and elements that negatively impact the healing process are vital. Patient falls, HAIs, disruptions to sleep/rest patterns and exposure to noise remain top concerns for patients and healthcare organizations. The following design solutions were implemented to reduce and mitigate these barriers to healing.

Within the design, we included “Nurse Servers” in every room, reflecting one of the most recent inpatient care innovations. Built-in, through-wall storage cabinets enable the restocking of linens, medical supplies, and medications directly from the hallway without entering the room. When you eliminate room ingress/egress, you minimize disruption and reduce potential external airborne pathogen exposure to the primary patient, while protecting other patients and visitors within the unit.

Flexibility

In-Room Dialysis: To enhance care, convenience, and efficiency, and eliminate patient transport, every patient room is equipped with fixed in-wall Dialysis Boxes.

Bariatric Capacity: These rooms are specifically prepared to accommodate and ensure accessibility and care for patients within this category, and likewise the clinicians responsible for their care.

Lighting: Soft nightlights positioned just above floor level create a gentle glow across the floor, allowing staff to navigate at night without waking patients. By reducing disruptions to sleep, these lights contribute to the healing process and promote a restful environment.

Patient Lifts: Furthermore, built-in patient lifts are installed in every patient room to help prevent falls and facilitate safe movement and repositioning of patients in their beds. This feature not only enhances patient comfort but also reduces the risk of bed sores and infection, ultimately improving patient outcomes and safety.

Less Stress, More Healing

Unit/Room: Every design element was carefully considered to ensure that the built environment and daily hospital operations contribute to patient rest and safety while promoting healing. By minimizing disruptions and creating a calming space, patients are more likely to experience restful recovery, reducing agitation and stress. Consequently, a well-rested patient positively contributes to a less stressful work environment for the care team.

Sound: Glass panels enclose the staff care team areas, reducing sound transfer into the corridors and patient rooms while still allowing staff to maintain clear sight lines to patients. Additionally, nourishment stations are available in each of the three CCU pods, providing convenient access to snacks and drinks for family members who are actively participating in their loved one’s care.

Lighting: Patient rooms feature large windows that can fill the space with natural light, offering scenic views of the waterfront or the city hillside. Evidence-Based Design asserts that exposure to natural light and calming views helps reduce patient stress and anxiety, accelerate healing, and enhance overall well-being.

Room Amenities for Family Members: Family presence is invaluable for healing, whether providing comfort to a patient or making critical healthcare decisions. Each patient room includes a dedicated visitor space with a sleeper sofa, allowing family to stay overnight or rest. Additional privacy is achieved with the addition of a curtain, giving patients and visitors a sense of personal space.

Wayfinding, Nourishment & Waiting: Unique ceiling treatments, wayfinding enhancements, and strategic lighting features are incorporated throughout the unit to improve orientation and navigation within the unit, further reducing stress for families during their visit.

A nourishment station within the waiting area ensures that visitors can access refreshments and snacks without having to leave the CCU floor.

Recognizing the emotional toll of CCU visits, a three-sided glass waiting room is located just off the elevator, offering breathtaking lake views and the city’s residential hillside. This peaceful retreat provides a space for reflection, reading, or simply taking a moment to breathe.

Staff Safety & Satisfaction:

Taking Care of the People Who Take Care of Others

Evaluating staff turnover rates, job satisfaction surveys, and feedback on the work environment helps measure the CCU design success in support of the healthcare professional. Additionally, for a healthcare organization, staff turnover, fatigue, and work-related illnesses or injuries can significantly impact the bottom line. ERDMAN’s design transcends patient and family comfort by enhancing staff efficiency, safety, and job satisfaction. Through user-group and stakeholder engagement, the design responds to and helps to mitigate the physical and emotional demands of critical care by streamlining workflows and accessibility to create a more sustainable and supportive work environment.

Workflow Optimization

“Nurse Servers,” as previously mentioned, are built into every patient room, providing staff with direct access to linens, medical supplies, and medications while treating their patients. By reducing the need for frequent trips to the supply room, this design helps minimize staff fatigue and improves efficiency in patient care.

Securely locked medication shelves, accessible from both sides of the cabinet, allow staff to quickly retrieve prescriptions and patient-specific medications without having to walk back to the Meds Room in the care team area. Similarly, soiled linen hampers and trash bins are accessible from the corridor, enabling housekeeping and Environmental Services staff to perform their duties efficiently without the need to enter each patient room.

Natural light is thoughtfully incorporated throughout the unit to create a warm and comforting environment. Large glass ICU doors, expansive exterior windows in patient rooms, and strategically placed windows at the ends of corridors allow sunlight to flow into both patient and care team areas, enhancing the overall atmosphere.

To further support efficiency, a pneumatic tube system is installed in each staff care team area, allowing for the rapid transport of pharmacy medications and lab materials without requiring long walks by care team members or couriers. Additionally, cameras in each patient room provide continuous monitoring, offering an extra layer of security and visibility to ensure patient safety.

Improving Patient Care & Staff Well-being

Metrics such as infection rates, patient recovery times, and incidence of medical errors are critical indicators of a CCU’s effectiveness. Prioritizing patient-centered and staff-friendly design elements, healthcare organizations can improve efficiency, clinical effectiveness, while reducing staff fatigue, injuries, and absence. A well-designed healing environment fosters patient relaxation and family member comfort, consequently contributing to a more positive workplace for caregivers. Ultimately, these thoughtful measures can help reduce staff turnover, ensuring a stable and engaged care team. Here are some examples:

Care Pods: The CCU layout is thoughtfully organized into “Care Pods,” minimizing travel distances between patients and care team, ensuring rapid response times and more efficient care.

Touch-Down Stations: To further enhance accessibility, hoteling “Touch-Down” Stations are strategically placed between pods, providing staff with convenient workspaces without requiring a return to the central care team area. This design saves steps and keeps caregivers closer to patients who require frequent attention.

Learning Spaces: Dedicated areas within the unit enable clinical teams to train on new procedures and medical advancements without leaving the floor. Our client’s culture promotes ongoing learning and ensures that high standards and clinical best practices are consistently upheld.

Respite & Collaboration: A staff lounge and conference room provide a space for brief respites and team huddles, supporting both mental recharge and collaborative discussions. To enhance convenience and security, a staff locker room was also incorporated, offering a secure space for personal belongings without requiring staff to leave the unit.

The driving force behind these improvements was direct staff engagement throughout the design process, ensuring the unit meets the real-world needs of those who provide care every day.

Designing An “Engaging” Experience

Evidence has proven that a design process that results in the most optimal outcomes for both patients and clinicians, involves end-users—the critical care team—in that process.

From project kick-off, through mockup rooms, in the early schematic and design development phases, critical care team leaders actively participated in each meeting. For our client, we invited their participation, which influenced design and provided invaluable input. Their involvement enabled them to share design plans with colleagues, gathering more feedback, compiling detailed notes to relay to the design team.

Additionally, the leadership arranged two tours of recently completed, CCUs at other hospitals, to include design team and staff. Hearing firsthand experiences from staff at these facilities sparked meaningful discussions on what worked well or could be improved, shaping our clients’ design.

With collective input, the facility management team constructed full-scale physical mock-ups of patient rooms and nurse servers using plywood, which were stocked with medical equipment and supplies. This permitted staff to the layout firsthand; this hands-on approach helped refine and optimize the final design. This approach sparked strong user buy-in, enthusiasm, and built pride in the new space.

Future Considerations

Looking ahead, ERDMAN will initiate post-occupancy evaluations at one-, three-, and five-year intervals, crucial to benchmarking project success against the original charter metrics. We anticipate improved patient outcomes, reduced staff injuries, and enhanced family experiences. Future data will provide insights that can inform future CCU planning and improvements.

In conclusion, the future of CCU design is centered on evidence-based design and creating adaptable, patient-focused environments that integrate advanced technologies and sustainable practices. By involving both clinicians and administrators in the design process and utilizing comprehensive performance metrics, healthcare facilities can develop CCUs that meet the evolving needs of patients and staff.
