The Cindarellas of surgery?

Hip fractures: 10% 30-day mortality

Emergency laparotomy:

15-40% 30 day mortality

in the elderly

Clarke, Eur j anaesth 2011

Traditional care for elderly emergency patients

Delay for surgery – logistics

Prolonged fasting /NPO

Medical optimization – badly defined

Perioperative resuscitation lacking

Opioid pain management – if any

HDU/ICU restricted capacity

Prolonged immobilization

Absence of multidisciplinary care

Challenges in optimizing

perioperative pathway

Triage for surgery – palliative care?

Optimized logistics to minimize surgical delay

Preoperative observation / HDU / ICU

Preoperative optimization – AB / Fluids/flow / analgesia

Specialists in theater

Intra/perioperative flow optimization – Fluids / inotropics

AHA Intervention:Common language: ”AHA” – focus

Continuous education: All staff groups in surgery, anaesthesia, ER and radiology

Optimized diagnostic logistics: CT abdomen

Early antibiotics: Administered on suspicion of pathology

Perioperative perfusion optimization: SV guided fluid and inotropic therapy

preop and 24 hrs postoperatively

Standardized anaesthesia: TIVA + Epidural - epi from preop – 3 days postop

Preventive perioperative intermediary therapy: triage for 24 h obligatory care in PACU

Standardized care plans on surgical wards (physiotherapy)

Interview & questionnaire

52 elderly patients

1 week + 6 months after surgery

Tengberg Dan med J 2017

1 week postoperative interview

”Hvad do you recall from the time before the surgery?”

Pain - 52%

”Did you consider refusing surgery?”

7 %

”Do you recall being asked about your wishes in regards to”:

- Resuscitation in the case of cardiac arrest?

- Intensive care or respirator treatment?

Yes / 14 %

6 months postoperatively questionnaire:

Status at preoperative admission: 91% from own home

No patients from nursing homes alive at 6 months!

”How do you assess your overall quality of life after the surgery”

”Good” / 75%

”Would you agree to have similar surgery again if your life depended on it”

Yes / 73%

6 months postop.; Are you active and about > ½ the day
