Ensuring the delivery of appropriate care and treatment is crucial for quality of care; length of stay in hospital may be irrelevant to this process.

The relationship between length of in-hospital stay (LOS) and quality of care is difficult. LOS is determined by a complex interweaving network of multiple supply and demand factors which operate at macro-, meso-, and micro-levels. These factors range from organisational culture and hospital bed availability, through availability of “step down” or intermediate care services, to the customs and cultures of the local populace.1–3 On top of these many factors there is also usually an underlying downward trend in LOS for any one particular condition over time.3

In health policy terms, LOS remains an easily measurable index of “efficiency” and is quoted as such in one of the most recent publications of the UK Department of Health NHS performance indicators.4 In this publication the percentage “improvement” or percentage reduction in LOS compared with the previous year is plotted for each local area.
