Surgical suite personnel
The management of a surgical suite must take into account all cooperating team members. The operating environment consists of interaction between surgeons, anesthesiologists, nurses, technicians, patients and visionary, committed hospital leadership.The necessity of management
Overhead costs include, but are not limited to, the space, technology and devices, pharmaceuticals and staffing. Hospital administrators have consequently focused their attention towards maximizing OR profitability, and thereby hospital profitability, through contribution margins. This focus, in addition to the boom in demand for elective surgery, has led to a rapid growth of OR facilities. Historically, nurses have been chiefly responsible for the daily functioning of the surgical suite. Increasingly, facilities are hiring a physician medical director for the OR, as represented by a surgeon, anesthesiologist, or both. In some instances, all three branches of surgery, anesthesia, and nursing will be represented in the daily OR management infrastructure. By working collegially, these three fields can mobilize all resources necessary to maximize ORPrinciples of operating room management
The decisions made by OR management should have a clear and definitive purpose in order to maintain consistency. In order of priority, governing principles of OR managers are to: (1) ensure patient safety and the highest quality of care; (2) provide surgeons with appropriate access to the OR; (3) maximize the efficiency of operating room utilization, staff, and materials to reduce costs; (4) decrease patient delays; and (5) enhance satisfaction among patients, staff, and physicians.Dexter, F. et al. An operating room scheduling strategy to maximize the use of operating room block time: computer simulation of patient scheduling and survey of patients’ preferences for surgical waiting time. Anesth Analg. 1999; 89:7–20. If OR management is properly performed ahead of time, all that doctors and nurses have to think about on the day of surgery is the patient. If management is poor, then the medical and nursing staff may waste efforts and resources to rush cases or juggle schedules, thus compromising attention toOperating room utilization
OR utilization is a measure of the use of anOperating room efficiency
Operating room (OR) efficiency is a measure of how well time and resources are used for their intended purposes. One way to analyze efficiency is to chart ''under-utilized'' and ''over-utilized'' time spent on a given day in thePerformance dashboard for a surgical suite
An operating room manager must select criteria, key performance indicators, or a dashboard of measurements, to assess overall functioning of a surgical suite. An example of an analytic tool used to rate surgical suites is reflected below. This scoring system was created in order to quantify the efficiency levels of surgical suites. Its economical efficacy has yet to be validated by formal studies. In addition, it was developed in the US and contains scoring elements that are applicable for an American surgical suite. It is therefore unlikely to be useful for operating room managers outside the US. OR efficiency measurements The above objective criteria can be computed from data commonly available in hospital administrative data systems.Excess staffing costs
Nothing is more important than to first allocate the right amount of OR time to each service on each day of the week for their case scheduling. This is not the same as the block time! To illustrate this imagine that two cases each lasting two hours are scheduled into OR #1 with OR nurses and an anesthesiologist scheduled to work an eight-hour day. The matching of workload to staffing has been so poor that little can be done the day of surgery to increase the efficiency of use of the staff. Neither awakening patients more quickly nor reducing the turnover time, for example, will compensate for the poor initial choice of staffing for OR #1 and/or how the cases were scheduled into OR #1. Optimal allocation of OR time should be based on historical use by a particular service (i.e., unit of OR allocation such as surgeon, group, department, or specialty) and then using computerStart-time tardiness
Start-time tardiness is the mean tardiness of start times for elective cases per OR per day. Reducing the time patients have to wait for their surgery once they arrive to the hospital (especially if the preceding case runs late) is another important goal for the OR manager. If a case is supposed to start at 10:00 am (patient enters OR), but the case starts at 10:30 am instead, then there are 30 minutes of tardiness. In computing this metric, no credit is given if the 10:00 am case starts early (for example at 9:45 am). The tardiness of start of scheduled cases should total less than 45 mins per eight-hour OR day in well functioning OR suites. Facilities with long work days will have greater tardiness because the longer the day, the more uncertainty about case start times. Having patients’ medical records ready to go with all needed documents is essential for on time starts.Case cancellation rate on day of surgery
Cancellation rates vary among facilities, depending partly on the types of patients receiving care, ranging from 4.6% for outpatients, to 13% -18% at VA medical centers. Recently published data from the UK estimate that 1 in 10 patients presenting for inpatient surgery have experienced a previous cancellation for their procedure, and that 1 in 7 patients being operated on had their procedure cancelled during a 1-week period in March 2017 in the UK National Health Service (NHS). Many cancellations are due to non-medical problems such as a full ICU, surgeon unavailability, or bad weather. OR cancellation rates can be monitored statistically. Well functioning OR suites should have cancellation rates less than 5%. Monitoring the cancellations correctly is calculated by taking the ratio of the number of cancellations to the number of scheduled cases.PACU admission delays
PACU admission delays can be expressed as a % of workdays with at least one delay of 10 mins or greater in PACU admission because PACU is full. It is important to adjust PACU nurse staffing around the times of OR admissions. Algorithms exist that use the number of available nursing hours to find the staffing solution with the fewest understaffed days.Contribution margin per OR hour
An OR suite that puts up with excessive surgical times can schedule itself efficiently but still lose its financial shirt if many surgeons are slow, use too many instruments, or expensive implants, etc. These are all measured by the contribution margin per OR hr. The contribution margin per hour of OR time is the hospital revenue generated by a surgical case, less all the hospitalization variable labor and supply costs. Variable costs, such as implants, vary directly with the volume of cases performed. This is because fee-for-service hospitals have a positive contribution margin for almost all elective cases mostly due to a large percentage of OR costs being fixed. For USA hospitals not on a fixed annual budget, contribution margin per OR hour averages one to two thousand USD per OR hour.Turnover times
Turnover time is the time from when one patient exits an OR until the next patient enters the same OR. Turnover times include cleanup times and setup times, but not delays between cases. Based on data collected at 31 USA hospitals, turnover times at the best performing OR suites average less than 25 mins. Cost reduction from reducing turnover times (because OR workload is less) can only be achieved if OR allocations and staffing are reduced. Despite this, turnover time receives much attention from OR managers because it is a key satisfier for surgeons. Sometimes the OR suite reduces turnover times (by providing more staff to clean the room for example) but new problems arise (not enough time for sterilizing instruments for the new case, can't bring patient to PACU because no beds) that were “hidden” by long turnover times. Times between cases that are longer than a defined interval (e.g., 1 hr because to follow surgeon is unavailable) should be considered delays, not turnovers.Prediction bias
Prediction bias in case duration are expressed as estimates per 8 hr of OR time. Prediction error equals the actual duration of the new case minus the estimated duration of the new case. Bias indicates whether the estimate is consistently too high or consistently too low, and precision reflects the magnitudes of the errors of the estimates. Efficient OR suites should aim to have bias in case duration estimates per 8 hr of OR time that is less than 15 minutes. A reason for bias can be surgeons’ consistently shortening their case duration estimates because they have too little OR time allocated and need to “fit” their list of cases into the OR time they do have. In contrast, other OR suites may have surgeons that purposely overestimate case durations to keep control/access of their allocated OR time so that if a new case appears their OR time was not given away. Remember that lack of historical case duration data for scheduled procedures is an important cause of inaccuracy in predicting case duration. In general, half of the cases scheduled in your OR suite tomorrow will have less than five previous cases of the same procedure type and same surgeon during the preceding year. It would be nice to have no uncertainty in case duration prediction. But, it is present. The problem is looking for a single number that is correct most of the time. You won't get accurate estimates by using historical case duration data. Rather, from the historical data you'll get an assessment of the uncertainty.Prolonged turnovers
Times between cases that are longer than a defined interval. (note: late arrival of a surgeon should be considered delays, not turnovers.)Operating room productivity
''Operating room productivity'' is the quantity and quality of output (typically surgical cases) from the surgical suite in contrast to the amount of input required (such as physicians and nurses and equipment for example). Many institutions believe that productivity (output/input) can be accomplished without sacrificing convenience (rapid access to open OR time such that a surgeon can book a case without having to wait) but these two aspects are not separable. Typically, the greater the ''operating room utilization'', the less the convenience (able to book cases when desired) as defined by surgeons and patients. This is because as utilization goes up there is less available open staffed OR time available on short notice. In other words, the greater the access and convenience, the lower is ''operating room utilization'' (because of the need for extra capacity), at least as perceived by hospitals and anesthesiologists. This high level of customer service of being able to book cases on short notice is one reason ambulatory surgery centers typically have lower OR utilization than big city hospitals. The outpatient surgery center usually has reduced overhead when compared to a big city hospital, and therefore can financially get away with lower OR use.Sociopolitical factors in management of the surgery suite: ''"OR Equilibrium"''
Management of the operating room suite must acknowledge that people are the primary resource. Although management science theory may tend to hold constant the preferences and bias of the individuals working in and utilizing the surgery suite, management of the surgical suite with regards to case scheduling is strongly influenced by personal, political, and economic relationships within an institution.Who is the main customer of your surgical suite?
To best align management goals with institutional objectives the OR director needs to identify the primary customer of the surgical suite. An OR can be completely balanced or it can be biased to one or more its constituents. The main people to consider are surgeons, anesthesiologists, nurses, the hospital (upper management), and of course the patient. A first step is to determine whose preferences or workload dominates the surgical suite. If surgeons are in large demand with small supply, then that may outweigh other interests. For example, a private facility may have surgeons who can pull their patients to another hospital if made to wait. As another example, in a private surgeon-owned surgery center, management may be directed as maintaining a particular partner's workload and the incentives are to schedule his/her cases with priority. The same supply/demand balance applies to anesthesia. The situation may exist where a specific surgery group will only work with its contracted anesthesia group. In this case, a manager may have to wait until the contracted anesthesiologist is ready for the case, even if this means idle OR time. This can be avoided in institutions where one group has exclusive rights and controls anesthesia privilege over all the ORs. This arrangement is seen commonly because it eliminates factions and streamlines anesthesia placement for cases, either elective or emergency. Hospital (Upper Management) run ORs are identified by those facilities where the hospital executives acting as agents for government authorities determine staffing and workload. Examples include hospitals in public health care systems like in European countries or the VAWhat are the preferences of the main customer in the surgical suite?
Once the manager has identified the critical few customers and the necessary many customers, then the next step is to determine their preferences and incentives. Surgeons will favor early block surgery times, rapid turnover, low cancellation rates, and on time starts. The hospital (upper management) will want the most surgical output with the least associated cost. Patients will likely favor reduced waiting times for surgery start. Finally, nurse managers and anesthesiologists will be inclined to highTheory and applications of operating room management
This discussion addresses capitalistic healthcare markets. A discussion ofPreoperative management issues
''Waiting time'' and ''operating room scheduling'' are the two key preoperative determinates. Waiting time prior to operation The time from surgical scheduling to check-in for the procedure is defined, for these purposes, as “preoperative wait time.” Use of a surgical suite depends greatly on, and increases as, the average length of time patients wait for surgery increases. As waiting time increases, more surgical dates (blocks) can be evaluated for a good match between a case's duration and the open times in the blocks. In some communities, competition among surgeons and hospitals may not allow the average length of time that patients have to wait for surgery to be as long as 2 weeks. An OR suite then cannot expect block time utilization from elective cases to exceed 90%, assuming that enough block time is allocated for a surgeon to complete all of the elective cases in the block time. For these purposes, wait time can be equated to the price of an object. The price for an object increases if demand increases and/or supply reduces for that object. Hence, “preoperative wait time” will increase as demand for surgery increases and/or surgical supply (operating room availability) reduces or fails to grow proportionally to surgical demand. By accurately gauging a patient population and an operative facility's capacity, an effective manager can minimize the wait for elective and imminent procedures while covering all emergency cases and without overextending the operative team.Scheduling operating room calendars
Case scheduling or correctly selecting the day on which to do each elective case so as to best fill the allocated hours is most important, much more so than, for example, correcting errors in predicting how long elective or add-on cases would last, reducing variability in turnover or delays between cases, or day-to-day variation in hours of add-on cases. Poor scheduling is often the cause of lost OR time. To more efficiently operate a surgical setting, managers may consider centralizing all scheduling to the operating room suite itself. Ideally, holding patient and surgeon preferences constant, an operating facility can identify cases and appropriately place them into predetermined time slots, or blocks. To examine scheduling challenges, consider three possible surgical scenarios: elective (e.g. cosmetic procedures, stable situations not increasing in severity), imminent (e.g. inflamed gall bladder removal, potential for worsening harm if situations not surgically corrected,) and emergency surgeries (e.g. burst appendix, situations in which death or disability is possible or likely). The majority of operative time is a combination of elective and imminent surgeries. Albeit a smaller percentage, emergency surgical cases must always be handled promptly in order to ensure patient safety. Emergency surgeries are often unforeseeable and present a scheduling challenge as a result. Therefore, from a management perspective, one must use the elective and imminent surgical cases as a guideline for pre-determining operative schedules, while allowing flexibility for the emergency situations that indubitably arise. The historical approach for scheduling operating room time is via analysis of previous surgical information. For example, to estimate how much time aIntraoperative management issues
Managers need to evaluate: 1) operating room leadership; 2) departmental leadership within the operating room; 3) interpersonal conflicts amongst the operating team; 4) physical layout and location of the operating room in relation to other integral departments; 5) operating room communication systems; and 6) patient turnover. Only then can options such as providing rewards and incentives for improved operating room efficiency, assessing logistical and system design, delegating responsibility, and implementing teamwork initiatives be instituted to produce more favorable outcomes for both the provider and the patient.Surgical suite leadership
Generally, an institution or private surgery center will have an agreed upon leader, generally dubbed the “Operating Room Manager.” The reporting structure is typically to a VP of surgical services. A manager may have the business and academic ability to operate a facility, but without the cooperation of staff and practitioners, most reform efforts will be futile. An OR manager must be in compliance with several internal and external governing bodies. Depending on the institution, a given manager may have to work closely with committees ranging from patient safety and medical staff safety boards to an auxiliary OR committee. TheDepartmental leadership within the surgical suite
This topic compartmentalizes each member of a surgical suite team to his/her department (e.g. surgery, anesthesiology, environmental services, housekeeping, etc.). The principle behind departmental leadership is the delegation of responsibility. An operating room manager must rely upon departments to uphold their respective regulations in addition to acting in the best interest of the overall institution. This interest directly relates toInterpersonal conflicts amongst the surgical suite team
The majority of accidents in technical professions have human error as causal elements. More critically, these errors tend to involve interpersonal issues: communications, leadership, conflict, flawed decision making, etc. A questionnaire circulated to operating room staff and professionals identified communication problems as an overwhelming barrier to operating room performance. This problem is a constant theme within healthcare and can disrupt an operating room and detract from operating room efficiency. It is imperative that a manager optimize personal issues and act quickly to correct them.Physical layout and location of the surgical suite in relation to other integral departments (i.e. radiology, pathology, etc.)
An effective manager must analyze the layout of each operating room individually and as a whole. The mass of new technologies and equipment, such as Endoscopic surgical procedures, in today's operating room is increasing. Crowding may adversely affect the abilities of the surgical team. Managers must act to appropriately modify pre-existing operating room space or by identifying key design issues during the conception and building of new facilities. Larger cases where more materials and instruments are used should be appropriately scheduled into rooms that can accommodate them. Likewise, the surgical suite ideally is placed in close proximity to support functions such as radiology, pathology, and intensive care. Creating unnecessary distance between these entities compromises both operating room efficiency andPostoperative operating room management
Notes
1. One possible solution to intrapersonal conflict within the operating theatre is medical simulation training. Large institutions are adapting simulator practices to teach everything from communication skills to proper clinical management of crises situations. By identifying interpersonal barriers in a closed environment, a manager can work with all parties involved to address and resolve these problems. Such interventions will reduce intraoperative error as a result of personal conflicts and serve to increase efficiency. 2. Ultimately, a manager may improve hospital functioning by providing rewards and incentives for improved efficiency, assessing logistical and system design, delegating responsibility, and implementing teamwork initiatives. These topics are beyond the scope of this article. 3. Those seeking to learn more about operating room management may find Dr. Franklin Dexter's website of helpReferences
