Kathleen P. Donohue and Susan M. Andrews
OBJECTIVES
At the conclusion of this chapter, the reader will be able to:
1. List three options available for conducting preoperative assessments and interviews.
2. Identify essential components of preadmission assessment.
3. Explain how the psychological and emotional assessment of a patient will help reduce anxiety on day of surgery.
4. Analyze the learning needs of ambulatory surgery patients.
I. TIMING OF PREOPERATIVE ASSESSMENT
A. Far enough in advance to ensure time for an appropriate evaluation
1. Obtain diagnostic testing and consultative services if needed.
2. Alter current medical regimen if necessary (e.g., anticoagulant therapy, glycemic control, hypertension).
3. Obtain equipment, supplies, and other items necessary for postoperative care.
4. Make arrangements in family schedule (home care, day care, transportation, etc.).
5. Prepare patient physically and emotionally for surgery.
B. Not too far in advance
1. Patient forgets preoperative instructions.
2. Diagnostic test results are outdated.
II. PURPOSE OF PREOPERATIVE ASSESSMENT AND PROGRAMS
A. Decrease potential delays and cancellations on day of surgery.
1. Provide for comprehensive assessments (nursing and anesthesia).
a. Potential problems identified and addressed before surgery
b. Nursing discharge plan
c. Complete systems review
d. Prior surgery, medical, and anesthesia history

(b) Major multi-system or cerebral trauma
(6) ASA 6 or (P6): patients declared brain dead whose organs are being harvested
(7) E: the E suffix denotes an emergency surgical procedure.

(i) Caregiver
(ii) Practice techniques (e.g., emptying drains, dressing changes, crutch walking, injections, etc.)

4. Reduce patient anxiety.
a. Provide clear and concise explanations.
b. Inaccuracies or misinformation may cause fear.
(1) Induction of anesthesia smoother in calm persons
(2) Recovery enhanced when patient less stressed
c. Promote the wellness concept.
III. BENEFITS OF A PREOPERATIVE ASSESSMENT PROGRAM
A. Identify issues needing further work-up before admission to avoid costly delays and cancellations.
1. History and physical
a. Performed within 30 days of the scheduled surgery
b. Completed
c. Updated within 24 hours of surgery
2. Advance directive
a. Need to bring a copy on the day of surgery
b. Opportunity to convey patient’s decision about end of life care, if so desires
3. Identify needed laboratory, diagnostic testing, and/or additional work-ups.
4. Identify any postoperative care needs.
a. Supplies, prescriptions, medication teaching and demonstration (e.g., enoxaparin sodium [Lovenox])
b. Equipment for home use (crutches, walker, continuous passive motion, continuous positive airway pressure, etc.)
c. Arrange for home care services (visiting nurse, home care aide, etc.).
d. Transportation home if outpatient surgery
(1) Avoid unnecessary postoperative stays.
(2) Potential unsafe transportation plans
e. Responsible adult (18 years or older), especially for first 24 hours
B. Allows for preoperative diagnostic screening
1. Based on specific individualized clinical indicators or risk factors (Figure 15-1)
a. Age
b. Preexisting disease or illness
c. Surgical procedure being performed

C. Allows for identification of potential safety issues
1. Patient and family history
a. Malignant hyperthermia
b. Pseudocholinesterase deficiency
c. Allergies including latex allergy/sensitivity
(1) Notify operating room (OR) before of day of surgery.
d. Use of narcotics for chronic pain
e. Use of street drugs/herbals
f. History of postoperative/postdischarge nausea and vomiting (PONV/PDNV)
2. Mobility issues
3. Ability to care for self if lives alone
4. Quality and amount of caregiver assistance
5. Ability and willingness to comply with preoperative instructions
a. Fasting and nothing by mouth (NPO) requirements
b. Smoking cessation
c. Necessary preoperative preparations
D. Allows for medication review and education
1. Current medications reviewed
a. Medication reconciliation starts preoperatively.
b. Name, dose, frequency
c. Herbals, supplements and over-the-counter medications
(1) Ask about specific supplements used. Patients often do not consider these “medications.”

a. Some medications may be stopped before surgery as determined by surgeon and/or anesthesia provider.
