3 Medical Facility Design and Ambulatory Surgery
Vanderbilt Bill Wilkerson Center for Otolaryngology and Communications Sciences, Nashville, Tennessee
Location: Nashville, Tennessee.
Purpose: Serves as a first-impression, gateway building for the Vanderbilt University medical campus.
Design Firm: ESa.
Size: A distinctive -sq.-ft. curving medical facility.
Site: Located on a tight, urban site.
Consolidated Services: The new facility consolidates services previously housed in four separate locations. These include:
Speech-language pathology clinic.
Scottish Rite Masons Research Institute for Communication Disorders.
New center for childhood deafness and family communication.
Voice center.
Clinic for otolaryngology and head and neck surgery.
Audiology clinic.
New administrative offices.
Faculty offices.
Classrooms.
Research treatment rooms.
Laboratories.
Architectural Design:
Materials: Utilizes concrete, masonry, and curtain walls, creating an eclectic blend that matches the hospital campus vocabulary.
Curved Curtain Wall: ESa used program components to create an elegant curved curtain wall with the smallest components on the top floors. This design avoids the typical "stepped box" effect seen in many similar designs.
Low Roofs: Incorporates low roofs for outdoor therapy spaces for children's programs and rehab.
Construction Over Existing Garage: Required building over an existing parking garage, necessitating a blended structure:
Concrete on the lower two floors.
Steel above to achieve lighter weight benefits.
Connector Design: ESa's design staggered, rather than stacked, connectors across the street from the existing hospital.
Highly Specialized Spaces: The center includes:
A two-story anechoic chamber, noted as the first in the country.
A reverberation chamber.
Acoustically isolated sound testing booths.
A therapy tank.
An indoor track.
Teaching Spaces: Designed to be flexible for lectures or interactive training programs, including:
An -seat lecture hall.
A computer training suite.
Multipurpose classrooms.
Eisenhower George and Julia Argyros Health Center, La Quinta, California
Location: La Quinta, California.
Architectural Firm: Boulder Associates.
Interior Designer: Jain Malkin.
Size: -sq.-ft.
Aesthetic Goal: To celebrate the healing power and natural beauty of the desert air and hot springs in the surrounding Coachella Valley, aligning with a green building aesthetic.
Exterior Design Features:
Fountain: A fountain with three granite stones pays tribute to the San Bernardino, San Jacinto, and Santa Rosa mountain ranges.
Entry: Features a dramatic sweeping tensile structure suspended over a broad arc, expressed in cobblestone paving that unifies and curves through the interior space.
Façade Materials: Includes traditional stucco common to desert architecture, complemented by unique terra cotta and aluminum panel rain screen.
Building Orientation: Positioned to take advantage of dramatic views of the foothills and mountains.
Glare and Overheating Minimization: Achieved by design features like fins, louvers, and screens that shade the building and enhance its desert appearance.
Interior Design Features:
Lobby:
Main lobby features a "rain" sculpture above a lush garden oasis, with water cascading over granite boulders.
An oculus at the end of the lobby provides a dramatic focal point against the desert sky.
Includes two reception desks flanked by stone-clad walls, several computer stations, an entertainment center, a children's play area, and a television with a digital aquarium.
Desert Theme: References to the light, color, and texture of the desert are woven into finishes and design features throughout.
Ceiling Design: Designers aimed to express the desert wind through textures and sinuous curves flowing through the ceiling.
Illuminated Sculpture: An illuminated sculpture of orange silk anemones above circular seating serves as a visual reminder of the bride of the desert sun.
First Floor: Contains a lab and suites for express care radiation, oncology, and imaging, each with interior design elements reflecting the overall concept. A healing suite provides a medical library and computers for patients.
Mezzanine: The design of the first floor flows upward to the second through an open mezzanine.
Second Floor: Includes a conference and education center for wellness and community services/events. Suites for women's wellness, primary care, and orthopedic medicine are on this level, each with unique identities and entrances.
Third Floor: Physicians' offices occupy most of the space on this floor, continuing the desert aesthetic.
Executive Health Center: An upscale center that continues the building's design theme, offering spa-like amenities such as walk-in rain showers and adjacent private dressing areas.
Executive Health Reception Area: Opens to sweeping mountain views with club chairs beneath a ceiling dome enhanced by LED lighting that sequences through rainbow colors.
Treatment and Waiting Areas: Television monitors display nature images and music from the Continuous Ambient Relaxation Environment (C.A.R.E.) channel, developed specifically for healthcare environments.
Ambulatory Surgery
Historical Context and Evolution
Traditional Practice (Pre-WWII): Physicians traditionally performed minor surgical procedures in their offices.
Post-WWII Shift: A significant number of minor procedures began to be performed in hospitals.
Major Procedures: Hospitals had been the primary location for major procedures since at least the late century.
Prevailing Philosophy: Traditional treatment emphasized extended postoperative recuperation.
Example: Dr. William Halsted prescribed a -day period of bed rest for hernia repair.
Recuperation Location: While long recuperation was anticipated, much of it was expected to occur at home, not in the hospital.
Century Changes:
Recuperative times shortened.
Patients were still expected to recuperate in a hospital bed.
Even minor procedures often mandated at least an overnight hospital stay, regardless of strict medical necessity, leading to several days of uneventful bed rest.
First Modern Ambulatory Surgery Programs:
: Butterworth Hospital in Grand Rapids, Michigan, initiated the first modern ambulatory surgery program.
: Followed by a program at the University of California at Los Angeles.
Surgicenter and Freestanding Units:
A Decade Later (c. ): Drs. Wallace Reed and John Ford opened Surgicenter in Phoenix, Arizona.
Nature of Surgicenter: It was a freestanding, totally self-sufficient unit, planned, built, and run by these two anesthesiologists.
Impact: Surgicenter sparked the nationwide development of additional such units.
Commonplace Practice (Late s): Ambulatory surgery became commonplace due to cost containment and the advent of Diagnosis-Related Groups (DRGs) influencing medical reimbursement. This included procedures in hospital outpatient departments, freestanding independent units, or hospital-affiliated settings.
Current Trend: Even for procedures requiring in-hospital recovery, the trend is towards short-stay surgery and early discharge.
Advantages of Ambulatory Surgery
Cost Reduction: Substantially reduces costs for medical care.
Enhanced Patient Care: Contrary to consumer expectations, cost savings do not necessarily come at the expense of quality or convenience; patient care may actually be enhanced.
Minimal Inconvenience:
Ambulatory surgery patients experience minimal disruption to their routines.
Families are also minimally inconvenienced, especially for procedures on children and infants.
Postoperative Care:
Largely handled by family members, saving money and benefiting the patient.
Children and infants avoid anxiety-provoking separation from parents, as family members often provide loving care that professional nursing staff find difficult to compete with.
Increased Individual Attention: Patients receive more individual attention from both family members/caregivers and staff specifically set up to treat ambulatory surgery patients.
Reduced Anxiety and Stress: The stress and anxiety associated with a hospital stay are eliminated.
Less Risk of Nosocomial Infection: Hospitalization exposes patients to hospital-borne infections. This risk is significantly reduced in same-day surgery settings.
Decreased Perception of Disability: Patients tend to feel less disabled or helpless and return to their normal lives more quickly.
Disadvantages of Ambulatory Surgery (and Solutions)
Patient Non-Compliance with Preoperative Instructions:
Problem: Patients may fail to follow instructions, most seriously regarding ingesting nothing the night before a procedure (NPO).
Risk: Under general anesthesia, this could lead to vomiting and aspiration of vomitus, potentially resulting in asphyxiation or pneumonia.
Solution: Meticulous preoperative education is required.
Transportation Requirements: Patients must arrange their own transportation to and from the facility.
Need for At-Home Assistance:
Assumption: Ambulatory surgery assumes competent at-home assistance is available.
Alternative: If direct family care is unavailable, professional home care is usually still less costly than an overnight hospital stay.
Requirement: Requires advanced planning.
Patient Anxiety Regarding Resuscitative Support:
Concern: Some individuals may worry that ambulatory units, especially freestanding ones, lack the advanced resuscitative support found in major hospitals.
Solution: Careful patient education is necessary to address these understandable concerns.
Common Settings for Ambulatory Surgery
Hospital-based Integrated Units:
Description: These are in-hospital units that share facilities with inpatient surgery.
Economic Viability: For smaller hospitals, this may be the only economically viable ambulatory surgery option due to capital costs.
(Other types mentioned but not detailed in the transcript: Hospital-based separated units, freestanding independent units, office-based units.)
