The COVID-19 pandemic has led to an unprecedented surgical backlog

Orthopaedic surgery had one of the highest rates of cancellation2

As at the end of December 2021, 94,807 patients​ were on the waiting list for elective surgery in​ the NSW public health system alone.1

"Although essential, cancellations place a heavy burden on patients and society. Patients' conditions may deteriorate, worsening their quality of life as they wait for rescheduled surgery."

-RAC, press release4

42% of Australians believe that there is still a risk of contracting COVID-19 in a healthcare setting with close to half (49.1%) delaying or cancelling healthcare appointments as a result of this risk.3

Can we ease the burden on hospitals through optimising length of stay?

Clearing the elective surgery backlog is a key priority as health systems enter the recovery phase from COVID-19.

Optimising length of hospital stay is one approach to help address and manage the backlog of orthopaedic surgeries.

Reduced length of hospital stay following joint replacement surgery is associated with improved outcomes

Improved Patient-reported outcomes
Improved Mobility and reduced pain
​​​​​​​Reduced risk of complications

Substantial body of evidence21 shows reduced length of hospital stay is associated with:

Improved patient 
Barker et al. 2006  41 Patients Comparative study of UKR: ERAS (n = 21) vs standard care (n = 20).
Husted et al. 2008 712 Patients Comparative study of THR (n = 370) compared with TKR (n = 342). ERAS only.
Husted et al. 2011 421 Patients Comparative study of bilateral TKR (n = 150) compared with unilateral TKR (n = 271). ERAS only.
Larsen et al. 2012 157 Patients Comparative study of TKR and UKR compared with normative population data. ERAS only.
Husted et al. 2010 563 Patients National survey of THR and TKR; outcomes data compared between hospitals with shorter and longer LOS. 
Husted et al. 2011 29 Patients Case series of revision knee replacement. ERAS only. 
Improved quality of life Larsen et al. 2012 211 Patients Comparative study of TKR and UKR compared with normative population data. ERAS only.
Larsen et al. 2010 196 Patients Comparative study of THR compared with normative population data. ERAS only.
Greater patient acceptance Hunt et al. 2009 35 Patients Qualitative interviews of primary THR ERAS vs standard care.

ERAS: Enhanced Recovery After Surgery; LOS: Length of Stay; THR: Total Hip Replacement; TKR: Total Knee Replacement; UKR: Uni-compartmental Knee Replacement.
