Nuts and bolts of preoperative clinics: The view from three institutions
ABSTRACT
Three directors of dedicated preoperative assessment clinics share their experience in setting up and running their programs. Standardizing and centralizing all or part of the preoperative evaluation process—obtaining patient records; the history and physical examination; the surgical, anesthesiology, and nursing assessments; ordering tests; and documentation and billing—increases efficiency. The savings achieved from minimizing redundancy, avoiding surgery delays and cancellations, and improved reimbursement coding offset the increased costs of setting up and running the clinic.
KEY POINTS
- Standardizing the preoperative assessment process helps ensure that regulatory, accreditation, and payer requirements and guidelines are met.
- Careful triage based on a patient’s history can help avoid unnecessary assessment of low-risk patients and ensure that necessary assessments for higher-risk patients are completed before the day of surgery.
- Perioperative assessment and management guidelines for various types of surgery and patient risk factors should be developed, continuously updated, and made available online to all providers within the institution.
- Electronic medical records allow standardization of patient information, avoid redundancy, and provide a database for research.
Anesthesia Perioperative Medicine Clinic at University of Chicago
By BobbieJean Sweitzer, MD
Detsky and Naglie have argued that the costs and clinical outcomes associated with any intervention must be compared with those of alternate strategies for treating the same patients,1 and I believe their point applies well to preoperative clinics. Although certain requirements of the Joint Commission and CMS must be met, as noted by Dr. Bader, they can be met in various ways. I will preface my comments by emphasizing that one size does not fit all: every institution must decide the best approach to preoperative assessment based on its patient population, the types of procedures it performs, and the volume it handles.
TRIAGE STREAMLINES THE PROCESS
Our preoperative clinic at the University of Chicago emphasizes triage. Not every patient should have to go to the trouble of coming in to see a provider. In the future, we will likely see more “virtual” preoperative assessments using devices in development, such as handheld ultrasonography machines. Just as patients can have their pacemakers and implantable cardiac defibrillators remotely checked via phone contact, more tools will one day be available for remote assessment.
Although not every surgical patient needs to come in to the preoperative clinic, every patient must have a physical examination. All patients will be seen on the day of surgery, so in some cases the physical exam may be able to wait until then. For example, an airway assessment need not be done ahead of time. Most anesthesiologists are prepared to manage airways on very short notice, so extensive advance planning is not always necessary.
Obtain basic info by questionnaire to save staff time
Information about the patient is key to triage, and it may be either paper- or computer-based. An initial priority should be to develop some mechanism for getting information from patients before the day of their procedure without a visit to the hospital or ambulatory surgery center.
We use a two-page paper questionnaire to obtain basic information from patients, including (among other pertinent questions) age, planned operation, names of the surgeon and primary doctor, past operations and medical history, allergies, a list of medications, social history (drug, alcohol, tobacco use), whether they have ever taken steroids, whether they have high blood pressure, and whether they can comfortably walk up a flight of stairs. We provide the primary care physicians and surgeons with blank questionnaires, which their patients can fill out in their waiting rooms or take home and fax to us (or drop off) later. The questionnaire gives us a good deal of essential information without using staff time.
Various computer-based and Web-based systems are also available for collecting basic patient information. Smaller institutions need not purchase an entire electronic medical record system, which can be very expensive. Some Web-based tools operate on a pay-per-use basis and can be very helpful.
Review the information to guide triage
We then review the patient information to determine the extent of preoperative evaluation required. Some patients, especially those scheduled at an ambulatory surgery center, are healthy enough that they can just come in on the day of surgery for an examination and an update of their information. Others will need an appointment at the clinic before the day of surgery for more extensive preoperative evaluation. For other patients, review of their questionnaire responses may prompt a phone call or e-mail from the clinic for more information to determine whether a day-of-surgery exam will suffice or whether evaluation in advance is needed. When in doubt, concerns raised by the questionnaire should be explored before the day of surgery to avoid surprises and allow sufficient time for a consultation, if needed.
STANDARDIZED GUIDELINES KEEP CARE CONSISTENT
We encourage our staff to minimize preoperative testing and ECGs. A majority of diagnoses are made based on the history and physical exam.2 Generally, a test should confirm what is already suspected and merely provide objective evidence when needed. Testing in this setting should not be done to “find out what is wrong” with a patient.
It is helpful to develop standardized guidelines for preoperative assessment and make them available to everyone in the institution via the Web. The guidelines should address recommended preoperative tests and management practices according to specific patient conditions or surgical procedures. The clear objective is to avoid disagreement about what a patient needs between the provider who evaluated the patient in advance and the surgeon or anesthesiologist who evaluates the patient on the day of surgery.
Our guidelines at the University of Chicago include recommendations for patients on long-term anticoagulant therapy, for patients with coronary stents, for medications that should be discontinued (and those that may be continued) on the day of surgery, and for numerous other conditions and issues. Our testing guidelines list indicated tests for various medical problems, which in turn link to other guidelines. Other links are based on the medications a patient is using or the type of operation that is planned.
We collaborated with our electrophysiology department to create guidelines for managing patients with pacemakers and defibrillators. Almost every patient with one of these devices has a little card associated with the device, and we ask the surgeons to copy the card and send it to the clinic if we will not be directly seeing the patient. Using a national database, the electrophysiology department can determine from the card the type of pacemaker or defibrillator a patient has, and they fax or e-mail us back a page of instructions to let us know whether the device requires special consideration during surgery, whether it should be checked preoperatively, and whether its battery needs replacing. With this system, we have markedly reduced problems on the day of surgery.
