BackgroundDelay to surgery for patients with hip fracture is associated with higher incidence of post-operative complications, prolonged recovery and length of stay, and increased mortality. Therefore, many health care organisations launch improvement programmes to reduce the wait for surgery. The heterogeneous application of similar methods, and the multifaceted nature of the interventions, constrain the understanding of which method works, when, and how. In complex acute care settings, another concern is how changes for one patient group influence the care for other groups. We therefore set out to analyse how multiple components of hip-fracture improvement efforts aimed to reduce the time to surgery influenced that time both for hip-fracture patients and for other acute surgical orthopaedic inpatients.MethodsThis study is an observational mixed-methods single case study of improvement efforts at a Swedish acute care hospital, which triangulates control chart analysis of process performance data over a five year period with interview, document, and non-participant observation data.ResultsThe improvement efforts led to an increase in the monthly percentage of hip-fracture patients operated within 24 h of admission from an average of 47% to 83%, with performance predictably ranging between 67% and 98% if the process continues unchanged. Meanwhile, no significant changes in lead time to surgery for other acute surgical orthopaedic inpatients were observed. Interview data indicated that multiple intervention components contributed to making the process more reliable. The triangulation of qualitative and quantitative data, however, indicated that key changes that improved performance were the creation of a process improvement team and having an experienced clinician coordinate demand and supply of surgical services daily and enhance pre-operative patient preparation.ConclusionsTimeliness of surgery for patients with hip fracture in a complex hospital setting can be substantially improved without displacing other patient groups, by involving staff in improvement efforts and actively managing acute surgical procedures.
