Developing a Bed Expansion Plan When There is a Deficit of Private Rooms

BACKGROUND

Prudent Hospital (PH) was originally designed to accommodate 250 licensed beds of which only 60 percent are in private patient rooms (150 beds). The remaining 100 beds are located in semiprivate rooms resulting is a total of 200 actual rooms (150 privates and 50 semiprivates). The current average daily census is 205 inpatients resulting in an average occupancy of 82 percent. The occupancy rate, however, is misleading because PH rarely places more than one patient per room in the two oldest nursing units ― each with 30 semiprivate rooms. Because of concerns with patient privacy, infection control and medical errors, along with undersized semiprivate patient rooms, PH leadership wanted to develop a bed expansion and replacement plan to address inpatient demand through the year 2020.

PH has experienced fluctuation in demand for inpatient beds over the past several decades. Beginning in 1980, with pressures from payers, both the rate of admission and length of stay dropped resulting in a rapid decline in inpatient utilization over the subsequent decade. The downward trend in inpatient workloads began moderating in the mid-1990s as a backlash to managed care. In a complete reversal of the trends of the early 1990s, PH experienced increased demand for inpatient care over the past few years. However, with the recent downturn in the economy, PH leadership is unsure of how to proceed.

Although some bed replacement and expansion was deemed necessary by all members of the planning team, the CFO was concerned about spending significant capital dollars given current economic conditions. PH executives were also not in agreement regarding the extent of the required expansion ― some wanted to plan for 100 percent private rooms while others were concerned that significant expansion would require additional staff at a time when budgets were tight and recruiting was difficult. Others were concerned about losing admissions to competitor hospitals who had more contemporary patient accommodations. Declining length of stay was also a concern. However, everyone agreed that the current use rate (admissions per 1,000 population) would most likely remain constant. They also agreed that the county’s updated population forecast for 2020 was reasonable given that it was much lower than previous estimates.

PLANNING APPROACH

The PH executive team was not interested in projecting the need for an absolute number of beds at some future date. Instead, PH wanted to identify the range of beds required based on the most optimistic versus pessimistic view of future market conditions ― particularly since decisions to expand or replace their inpatient facilities would start a chain reaction of events and involve a long-range commitment of dollars, staff time, and operational disruption.

All members of the planning team agreed that a sensitivity analysis was needed to model the impact of different planning assumptions on future bed need and to evaluate the magnitude of renovation or construction. They also wanted to look at the relationship between high-bed need and low-bed need scenarios and the resulting number of private patient rooms that could be available.

As shown in the table on the following page, different scenarios were modeled based on varying market share, length of stay, and occupancy rate assumptions with the use rate and projected service area population held constant as follows:

  • Population. A population increase of nine percent was projected in all scenarios. The medium bed need scenario reflects the status quo relative to all other variables.

  • Use rate. The use rate was projected to remain constant in all scenarios at 110.5 admissions per 1,000 population in PH’s service area.

  • Hospital market share. PH’s market share was projected to decrease by five percent in the low-bed need scenario and increase by 10 percent in the high-bed need scenario.

  • Hospital admissions. PH’s admissions were calculated by applying the use rate to the projected service area population and multiplying by PH’s expected market share.

  • Average length of stay. PH’s current average length of stay (LOS) was reduced by one-half day in the low-bed need scenario and maintained in the high-bed need scenario.

  • Average daily census. The expected average daily patient census for PH was calculated by multiplying the projected admissions by the length of stay and dividing by 365 days.

  • Bed need. PH’s projected bed need for 2020 was calculated based on varying occupancy levels.

The target occupancy rate was also an issue for PH. The hospital typically used 80 percent occupancy as a target. However, PH realized that organizations with all private patient rooms are re-evaluating this target. Given the high cost of construction and planning uncertainties, PH’s CFO was willing to accept the risk of not accommodating all demand during peak periods to avoid having vacant patient rooms during average census periods. The Director of Planning noted that, statistically, a hospital with all private patient rooms should be able to maintain a higher occupancy level than one with a large number of semiprivate or multiple-bed rooms. On the other hand, targeting a higher occupancy level would not be practical for PH if it maintained its current high percentage of semiprivate patient rooms. PH decided to use a target of 85 percent occupancy assuming that it needed to increase the number of private patient rooms regardless.

The PH leadership team had the following observations regarding the 2020 bed need projections:

  • The nine percent increase in population alone (all scenarios) results in the need for an additional 12 beds (total of 262 beds at 85 percent occupancy).

  • In the high-bed need scenario, a 10 percent increase in market share results in the need for an additional 39 beds (total of 289 beds at 85 percent occupancy).

  • In the low-bed need scenario, with both the market share and length of stay reduced, 24 less beds would be needed (total of 226 beds at 85 percent occupancy).

  • Assuming a lower occupancy target of 80 percent versus 85 percent results in the need for 14 to 18 more beds depending on the scenario; assuming a higher occupancy rate of 90 percent versus 85 percent results in the need for 12 to 16 fewer beds.

ANALYSIS

The graph below displays the high-bed need and low-bed need scenarios projected through 2020 with varying occupancy assumptions. The hospital’s existing licensed capacity of 250 beds is also shown along with the existing number of patient rooms ― regardless of whether some were originally designed to accommodate two patients.

Low-bed need scenario. Since this facility was originally designed with a total of 200 patient rooms (150 privates and 50 semiprivates), in the low-bed need scenario PH could essentially use all the patient rooms as privates during the average daily census (192 patients) while retaining a limited number of semiprivate rooms to accommodate peak census periods and maintain its current licensure. No expansion would be necessary through 2020 unless PH desired to upgrade or replace some of the existing patient rooms ― enlarge the patient rooms and provide wheelchair accessible toilet/shower rooms and additional amenities.

High-bed scenario. Bed expansion would definitely be required in the high-bed scenario to accommodate the 2020 bed need. If the high-bed need scenario comes to fruition, PH considered the following possible bed expansion strategies:

  • Conservative approach ― construct 40 additional private patient rooms thus increasing the proportion of private patient rooms to 66 percent.

  • Aggressive approach ― construct 90 additional private patient rooms resulting in 100 percent of the projected beds for 2020 in private rooms.

CONCLUSION

The PH executive team recognized that even though the low-bed need scenario resulted in less beds than were currently licensed, PH was effectively only using 220 beds rather than 250. All of the 60 semiprivate patient rooms in the two oldest nursing units were too small to accommodate two patients given the amount of equipment and technology used today to deliver inpatient care. They decided that even in the low-bed need scenario, they still needed to replace at least 30 beds. This would result in a total of 230 patient rooms that could all be used as privates if the low-bed need scenario occurs ― assuming that the resulting number of beds per nursing unit did not compromise efficient staffing patterns.

The PH executive team agreed on the goal of having enough patient rooms to accommodate the 2020 projected average daily census of 245 patients (high-bed scenario). The existing semiprivate patient rooms would be maintained and deployed during high census periods if the high bed need scenario evolves.

Ultimately, PH developed a plan to construct 72 new beds, all in private rooms. The remaining 20 semiprivate patient rooms would be maintained to accommodate peak census periods. Depending on the future bed scenario that evolves, the two oldest nursing units could be redeployed for same-day/observation patients, although the beds could still be used as overflow inpatient beds at some point if necessary. With the existing 150 private patient rooms, 30 converted private rooms (existing semiprivates), 72 new private patient rooms, and 20 remaining semiprivate patient rooms, PH could expand it licensure to 292 beds to accommodate the high bed need scenario for 2020 if needed. If this scenario does not come to fruition, the oldest nursing units could be permanently decommissioned for an alternative use and all the remaining semiprivate patient rooms could be converted for single-patient use. This would result in a total of 242 private patient rooms.

Like many hospitals, PH was challenged with planning a staged conversion of semiprivate patient rooms to privates over time. However, they hoped to plan for additional flexibility that could offset forecasting inaccuracies. If the low-bed need scenario plays out, then some of the existing semiprivate patient rooms could be used for single occupancy. On the other hand, if the high-bed need scenario comes to fruition, then PH would need to deploy some of the rooms as semiprivates during peak census periods. back to top

Hospitals Are Adding Complementary and Alternative Services

OVERVIEW

In response to patient demand, hospitals are integrating complementary and alternative medicine services with the conventional services they typically provide according to a survey released last fall by Health Forum, the American Hospital Association subsidiary that publishes Hospitals and Health Networks. According to the survey, 37 percent of responding hospitals indicated they offer one or more complementary and alternative medicine (CAM) therapies, up from 26.5 percent in 2005.

CAM is not based solely on traditional Western allopathic medical teachings and may include acupuncture, homeopathy, herbal medicine, and massage therapy, along with diet and lifestyle changes. The focus is to treat the whole person ― body, mind, and spirit.

SURVEY FINDINGS

Other survey findings include:

  • 84 percent of hospitals indicated patient demand as the primary rationale in offering CAM services and 67 percent stated clinical effectiveness as their top reason

  • The majority of hospitals that offered CAM were urban (72 percent) and most were medium-sized (100 to 299 beds)

  • Massage therapy is one of the top two services provided in both outpatient and inpatient settings

  • Most CAM services are not reimbursed by insurance and are paid for out-of-pocket by patients

Planning a More "Virtual" Center of Excellence

BACKGROUND

For several decades, healthcare organizations have been developing Centers of Excellence (CoE) to better compete for market share, research dollars, philanthropy, and scarce subspecialists in specific programs. Promoting a specific program within the healthcare organization’s broader portfolio of services helps to attract the critical mass and resources required to make it successful. Centers of Excellence are commonly developed for cardiac care, cancer treatment, neurosciences, orthopedics, pediatrics, and women's health. Various other clinical programs and specialties may also be candidates for a Center of Excellence.

From a facility planning perspective, decisions to develop specific Centers of Excellence are complicated. Historically, these centers were envisioned as freestanding facilities with the name prominently displayed on the building’s facade. Before high-speed Internet/Intranet connections, this concept was promoted to improve collaboration and communication among the healthcare providers as well as to enhance customer service.

CURRENT TREND

Healthcare organizations are increasingly looking for more cost-effective ways to achieve a similar result while spending fewer capital dollars. To accomplish this, they are focusing on the specific elements that give customers the perception of a “center” to identify which functional components and services will need to be physically adjacent versus virtual and connected electronically.

Unless the center is being constructed as a freestanding facility on a new site, some services could be located within existing space while others are in a new addition. The trade-offs between the cost (initial capital cost and ongoing operational costs) of achieving physical adjacency versus settling for less-then-perfect convenience for the customer need to be reviewed and weighed carefully. The potential for increased revenue, reimbursement, and the demands of donors, partners, or investors may also impact the requirements of the physical design. Unfortunately, physicians often have difficulty imagining a “center” that is not an imposing edifice or at least a freestanding building.

For example, a Heart Center may be developed on an existing hospital campus by creating a dedicated patient entrance that leads directly to the Heart Center reception desk and intake area. An adjacent cardiac resource center for patients and family members may provide educational materials on heart disease and private carrels for viewing videos or accessing computer resources. A contiguous conference room may also be provided for group education on various aspects of heart disease and the lobby may be used for periodic health promotion and assessment activities as well as for fund raising.

However, all other Heart Center components may be located within an existing outpatient facility or within the hospital and accessed via an elevator or a short walk down an adjacent corridor ― including cardiologist and cardiac surgeon offices, non-invasive cardiac diagnostics, cardiac catheterization lab, cardiac rehabilitation, and other related services.

CONCLUSION

From the patients’ perspective, once they arrive at a well-identified entrance and are greeted by a friendly and competent receptionist, they are generally oblivious to where they are treated as long as signage is effective and they are not asked to walk a great distance. An elevator ride with a short walk to space in an existing building is not considered a hardship even though the physician leaders may feel that new construction is mandatory. back to top

Technology

 

The Future of Surgery is Here Now

OVERVIEW

The past two decades have witnessed a revolutionary transition in surgical technique and technology. Traditionally, surgeries had been performed in the open manner, in which large incisions were required for the surgeon to plainly observe and manipulate the surgical field. These incisions inevitably created significant patient trauma ― substantial pain and suffering, extended recovery time, prolonged pain management, and elevated costs.

Approximately 20 years ago, surgeons began practicing a new approach to performing surgery, an approach that came to be known as minimally invasive surgery, or MIS. During this era, tiny cameras in instruments called endoscopes or laparoscopes were introduced. These visual and surgical aids could be inserted in the patient's body through small ports. Although revolutionary in its positive effect on patient trauma and recovery times, MIS encountered significant technical drawbacks. The surgeon operated using a standard 2-D monitor instead of looking at his or her hands. The resulting image flattened the natural depth of field, and the fixed-wrist instruments limited his/her dexterity. The lack of 3-D visualization of the operative field, the poor ergonomic design and reduced control were major roadblocks to further progress. As a result, this type of MIS turned out to be suitable for a narrow range of surgical procedures.

In the late 1990s, another evolutionary stage in the development of surgical technique was achieved with the application of robotics to surgical technology. At the forefront of this new era, Intuitive Surgical introduced the da Vinci Surgical System® which is now used at medical centers throughout the U.S. to perform complex surgical procedures including general, cardiac, thoracic, gynecologic, and urologic procedures. It is the only commercially available technology that can provide the surgeon with the intuitive control, range of motion, fine tissue manipulation capability and 3-D visualization characteristic of open surgery, while simultaneously allowing the surgeon to work through tiny incisions typical of minimally invasive surgery.

HOW IT WORKS

With the Da Vinci Surgical System, the surgeon performs surgery with a surgical arm unit that positions and maneuvers detachable surgical EndoWrist instruments. These pencil-sized instruments (with tiny, computer-enhanced mechanical wrists) are designed to provide the dexterity of the surgeon's forearm and wrist at the operative site through entry ports less than one centimeter. This enables the surgeon to enter the body through keyhole incisions to perform surgery. One port allows access for the endoscope, a tiny camera that is attached to a fiber-optic cable. The other ports provide access for surgical tools. Instead of the surgeon holding the tools, the robots wrists do ―  bending back and forth, side to side, and rotating in a full circle ― thereby providing greater range of motion than humanly possible. The wrists of the robot mimic the motions made by the surgeon, who sits at a console remote from the patient. The surgeon peers through an eyepiece that provides high-definition, full-color, magnified, 3-D images of the surgical site provided by the endoscope. The physician moves his or her hands, which are attached to manipulation controls and the robot follows along. An important element of this technology is that the built in computer enhances the surgeon's hand movement and renders it more precise with less tremors ― an important element in delicate surgery.

KEY OPERATING ROOM COMPONENTS

The da Vinci Surgical System consists of an ergonomically designed surgeon’s console, a patient-side cart with four interactive robotic arms, the high-performance InSite Vision System and proprietary EndoWrist instruments. The four components can be accommodated in a standard operating room that is designed for major surgical procedures (e.g., 600 net square feet). 

  • Surgeon Console. The surgeon operates while seated at a console viewing a 3-D image of the surgical field. The surgeon's fingers grasp the master controls below the display, with hands and wrists naturally positioned relative to his or her eyes. The system seamlessly translates the surgeon's hand, wrist and finger movements into precise, real-time movements of surgical instruments inside the patient.

  • Patient Side Cart. The patient side cart provides either three or four robotic arms — two or three instrument arms and one endoscope arm — that execute the surgeon's commands. Supporting surgical team members assist in installing the proper instruments, prepare the ports in the patient’ body and supervise the laparoscopic arms and tools being utilized.

  • EndoWrist Instruments. A full range of proprietary EndoWrist instruments is available to support the surgeon while operating. The instruments are designed with seven degrees of motion that mimic the dexterity of the human hand and wrist. Each instrument has a specific surgical mission such as clamping, suturing and tissue manipulation. Quick-release levers speed instrument changes during surgical procedures.

  • Vision System. The Vision System, with high-resolution 3-D endoscope and image processing equipment, provides the true-to-life 3-D images of the operative field. Operating images are enhanced, refined and optimized using image synchronizers, high-intensity illuminators and camera control units.

TELEMEDICINE WILL BE NEXT

The da Vinci Surgical System ― with patient on the operating room table and the surgeon console physically separated ― can theoretically be used to operate over long distances. Although this capability is not currently the primary focus of Intuit Surgical it will certainly be the next evolution of this exciting technology. back to top
