Perioperative Care of Elderly Patients with Hip Fracture J Rush Pierce Jr, MD, MPH Hospitalist Best Practices Conference May 5, 2009
A 78 year old woman fell at church. She complained of left hip pain and was unable to arise. EMS was activated and transported her to the ED where x-rays disclose a hip fracture. She has a history of hypertension, hyperlipidemia, and coronary artery disease. She suffered a myocardial infraction seven years ago. She has not had any chest pain or symptoms of CHF. Her medicines are lisinopril, atenolol, aspirin, and atorvastatin. She lives with her husband who reports that she is active, does housework and walks everyday. She has had some memory difficulty and has poor vision. On examination she complains of pain, The left leg is external rotated. Heart and lung exam is normal. She has no edema. Her Folstein MMSE is 23 and Mini COG is 2. Her laboratory reveals a normal CBC and electrolytes. BUN is 25 and creatinine is 1.0. CXR is normal. EKG shows Q waves in limb leads 2, 3, and AVF.
Hip fracture in the elderly How will this likely affect her life? What evaluation does she need before surgery? What is the best evidence based care? Preoperative Operative Postoperative What can we do to prevent another hip fracture in the future?
Hip Fracture – epidemiology & natural history 350,000 hip fxs yearly in USA Lifetime risk for hip fx = 17.5% ♀, 6.0% ♂ Mortality: 5% during index hospitalization 3 mos one year 50% require assistance one year 25% in one year
What type of pre-operative evaluation does she need?
Assessing the cause of the fall Did she have syncope? Most falling in the elderly not due to syncope Syncope suggest possibility of cardiac arrhythmias Has she fallen before (6 months)? Suggest frailty and poorer prognosis Medication review especially important
Causes of syncope in the elderly Ungar A, et al. J Amer Geriatrics Soc 2006;54: “In contrast with previous reports, prodromic symptoms were remarkably frequent in this older population but proved to be poorly specific and, hence, of limited utility in orienting the diagnosis toward neurally mediated syncope.”
“She needs Clearance”
“We need clearance!”
Preoperative Risk Assessment
Preoperative management Traction – no benefit with regard to pain or ease of fracture reduction Pressure sore prevention Foam mattress (RR = 0.34) Alternating pressure mattress (RR=0.20) Beta blockers – recent meta-analysis showed no benefit for non-cardiac surgery (Lancet Dec 6;372: )
Meta-analysis of peri-operative beta blockers 33 trials included 12,306 patients. β blockers were not associated with any significant reduction in the risk of all-cause mortality, cardiovascular mortality, or heart failure, but were associated with a decrease (odds ratio [OR] 0·65, 95% CI 0·54–0·79) in non-fatal myocardial infarction (number needed to treat [NNT] 63) and decrease (OR 0·36, 0·26–0·50) in myocardial ischaemia (NNT 16) at the expense of an increase (OR 2·01, 1·27–3·68) in non-fatal strokes (number needed to harm [NNH] 293). The beneficial effects were driven mainly by trials with high risk of bias. For the safety outcomes, β blockers were associated with a high risk of perioperative bradycardia requiring treatment (NNH 22), and perioperative hypotension requiring treatment (NNH 17). We recorded no increased risk of bronchospasm. (Lancet Dec 6;372: )
Her children are coming from out of state and ask that surgery be delayed for two days until they arrive. What is the best timing of surgery in this woman?
Timing of Surgery Early repair (24 – 48 hrs) [Evidence based, mostly level 2] ↓ one-year mortality ↓ pressure sores (RR= 0.46) ↓ major medical complication (RR=0.26) Reduced LOS by 1.94 days Reasons to delay surgery [Opinion] Acute coronary syndrome Acute CVA Sepsis Severe hypoxemia
Hip fracture in the elderly - anatomy Femoral neck (1/3) Non displaced– usually internal fixation with nail/pin Displaced - hemiarthroplasty Intertrochanteric (2/3) Open reduction with internal fixation (ORIF) Zuckerman. N Engl J Med 1996;23:

Parker and Gurusamy. Disability and Rehab 2005; 27:1045 – 1051.
Operative management Type of surgery - arthroplasty for displaced femoral neck fxs Pre-operative antibiotics (1 or 2 doses of long-acting cephalosporin) Decreased post-op wound infection (RR=0.36) Decreased post-op UTI (RR=0.66) Regional anesthesia Decreased 30 day mortality (RR=0.69) Decreased proximal DVT (RR=0.64) Decreased post-op pneumonia (RR=0.61)
Post-operative management Pain management Decreased cardiac complications with epidural (1 study); better pain management with epidural Expert opinion: avoid meperidine & propoxyphene Urinary catheter UTI occurs in 25% Little evidence about catheter type and UTI Post-op urinary retention – normal voiding returns 4.3 days sooner with intermittent vs. indwelling catheter (1 study)
Thromboembolic prophylaxis Prevalence: DVT = 48%; fatal PTE = 4 -14% Benefit to all modalities (RR~0.6); no one clearly preferred, most use an anticoagulant Heparin, LMWH, low dose coumadin, ASA + SCD Begin preoperatively Heparin, coumadin - day before LMWH – not before 12 hrs preoperatively Duration – not well studied; suggest need for 6 weeks
Post-operative management (cont) Nutrition Oral supplements reduced LOS (one study) Multidisciplinary team No level 1 benefit shown but difficult to study
Rehab and Recovery Early mobilization important – 24 hours [evidence based] Earlier discharge ↓ costs ↑ functional status Gait training and occupational therapy decrease risk of recurrence [evidence based] Organized rehab assoc with 10% ↓ in death and institutionalization - pts with mild dementia most likely to benefit [evidence- based]
Is post-operative delerium likely in this woman?
Postoperative delerium Pre-existing dementia very common, but often not diagnosed Pre-operative Mini-Cog (0-2 + abnormal Clock drawing test) five times as likely to develop
Postoperative delerium – assessment and treatment Look for treatable causes Hypoxemia Electrolyte abnormalities Hypotension Avoid sedative/hypnotics, drugs with anticholinergic properties, narcotics Reassurance, reorientation, geriatric nursing care Huddleston & Whitford: Mayo Clin Proc 2001; 76:
How do we prevent this from happening again?
Hip fracture – prevention of recurrence Almost all accompanied by osteopenia or osteoporosis Calcium and Vit D in hospital Consider bisphosphonates Hold estrogens (thromboembolic potential) Fall prevention
Falls in the Elderly - Epidemiology 30% community dwelling adults over 65 years old fall at least once each year Over 50% nursing home residents fall yearly Over 10% of falls result in serious injury About 5 – 6 % of Medicare expenditures result of falls
Medications associated with hip fractures in epidemiologic studies Benzodiazepines Antidepressants Antipsychotics
Fall prevention – evidence of benefit Education – not helpful Exercise programs (balance training > strength or endurance) – benefit only for targeted community dwelling adults Environmental assessment – benefit outside home as well as in home Withdrawal of psychotropic drugs – but studies show that most patients resume withdrawn medications within one year
Fall prevention – extent of benefit Most studies show modest (10 -15% reduction in falls) Best multi-component intervention programs show 35% reduction (30% - 20%) Repeated falling in the elderly often predicts general physical and cognitive decline – review living situation and driving
Clinical Bottom Line Telemetry for syncope [opinion] “Clear” almost all patients Push for early surgery (24-48 hrs) and regional anesthesia Pre-operatively order a mattress, peri- operative antibiotics, DVT prophylaxis Post-operatively get Foley out; ambulate early; order PT/OT; avoid meperidine & propoxyphene; anticipate delerium; order Ca and Vit D; consider bisphosphonates; rehab
