7 Hospital adverse events often result in a longer length of stay (see references on next slide) We developed a new indicator that uses the unexpectedly long length of stay (UL-LOS) as a potential risk factor for unsafe care.

Indicator: Percentage of patients with an unexpectedly long length of stay (UL-LOS) Methods: Based on a prolonged length of stay of more than 50% Standardisation for patients’ age, primary diagnosis and main procedure Three strata of hospitals: 31 general hospitals 24 tertiary teaching hospitals 8 university medical centres 9
Why based on a prolonged length of stay of more than 50%? to include patients that stayed longer because of complications and adverse events and not patients that just stayed a little bit longer because of variations in the treatment, such as in logistics 10
Example - patient of 18 years old - appendicitis - appendectomy Expected LOS 3,4 dagen 3,4 + 1,7 = 5,1 days Actual LOS 6 days or more: UL-LOS 11
13 How does the Inspectorate use this indicator? Most important problem: hospitals without UL-LOS percentage Other hospitals: High percentage is an important signal Inspectors ask to inspect detailed information per specialism Patients with UL-LOS: record reviewing to learn what went wrong
15 PRO’s and CON’s of working with one key indicator Pro: Les administrative burden for caregivers Much easier for the inspector Contra: High demands regarding to this specific indicator: validity reliability comparability Outcomes are not compensated by other indicators!
