Use radiography rarely, not routinely, for hip hemiarthroplasty.

PURPOSE: Hip hemiarthroplasty (HA) is a commonly performed operation. A post-operative radiograph forms part of the routine hip fracture pathway, although patients are often mobilised prior to this investigation. This study seeks to provide evidence for a pragmatic clinical change to optimise patient safety and allocate limited resources within the National Health Service (NHS). METHODS: We undertook a retrospective database review of 1563 HA procedures to assess whether the routine ordering of check radiographs played an important role in a patient's post-operative care. RESULTS: 18 (1.2%) mechanical complications led to a return to theatre within 6 weeks of the index procedure. All were dislocations. Ten had a normal post-operative radiograph and five had documented suspicion of dislocation prior to radiography. The post-operative check radiograph was the sole identifier of dislocation in only three patients (0.2%). All three of these patients were pre-morbidly bed bound and non-communicative due to cognitive impairment (AMTS 0/10). CONCLUSION: Unless a patient is pre-morbidly bed bound and cognitively impaired, routine post-operative radiography following HA surgery is of little clinical benefit, yet may carry considerable risk to the patient and cost to the NHS. A pragmatic compromise is to perform intra-operative fluoroscopic imaging.

Early and ultra-early surgery in hip fracture patients improves survival.

BACKGROUND: Hip fracture is a common injury with associated high mortality. Recent drives by the Department of Health have sought to prioritise these patients' care. In April 2010, the Best Practice Tariff was introduced in England and Wales. This offers financial incentives to institutions that provide holistic care and surgery within 36h for hip fracture patients. The England and Wales National Institute for Health and Clinical Excellence (NICE) published its first guidance on hip fracture management in June 2011, and emphasised the need for surgery on the day or day after admission. In spite of the emphasis placed on this injury, the predictors of in-hospital mortality remain ill-defined. In particular the effect of the timing of surgery remains contentious. OBJECTIVE: To address the issues raised by NICE around surgical timing and examine whether surgery before a 36h watershed improves survival. In addition, to examine survival outcomes for each 12h watershed following admission. MATERIALS AND METHODS: Prospectively collected data on 2056 patients presenting to our unit with hip fractures between February 2008 and May 2011 were retrospectively reviewed. Multivariate regression analysis was used to correct for confounders, and so determine the effect of various parameters on in-patient mortality. RESULTS: Age (p<0.0001), male-gender (p<0.0001), source of admission (p<0.05), ASA-grade (p<0.0001) and delay of surgery (p<0.01) were associated with an increased risk of in-hospital mortality. The adjusted odds of in-hospital mortality were 1.58 (p<0.05) times higher in those undergoing surgery after 36h compared to surgery before this time. Early surgery (within 24h) resulted in reduced in-hospital mortality when compared to the 36h watershed. Similarly ultra-early surgery (within 12h) was even better still (adjusted odds ratio 3.9 p<0.05). CONCLUSIONS: Expeditious surgery is associated with improved patient survival. Other predictors of in-hospital mortality include age, gender, in-hospital fracture and ASA-grade. Ultra-early surgery (within 12h) reduces risk of in-hospital mortality.
