Echocardiography is commonly used in hip fracture patients to evaluate perioperative cardiac risk. However, echocardiography that delays surgical repair may be harmful. The objective of this study was to compare surgical wait times, mortality, length of stay (LOS), and healthcare costs for similar hip fracture patients evaluated with and without preoperative echocardiograms. A population-based, matched cohort study of all hip fracture patients (aged over 45 years) in Ontario, Canada between 2009 and 2014 was conducted. The primary exposure was preoperative echocardiography (occurring between hospital admission and surgery). Mortality rates, surgical wait times, postoperative LOS, and medical costs (expressed as 2013$ CAN) up to one year postoperatively were assessed after propensity-score matching.Aims
Methods
In this study we evaluated whether pre-operative
Western Ontario and McMaster Universities (WOMAC) osteoarthritis
scores can predict satisfaction following total hip arthroplasty
(THA). Prospective data for a cohort of patients undergoing THA
from two large academic centres were collected, and pre-operative
and one-year post-operative WOMAC scores and a 25-point satisfaction
questionnaire were obtained for 446 patients. Satisfaction scores
were dichotomised into either improvement or deterioration. Scatter
plots and Spearman’s rank correlation coefficient were used to describe
the association between pre-operative WOMAC and one-year post-operative WOMAC
scores and patient satisfaction. Satisfaction was compared using
receiver operating characteristic (ROC) analysis against pre-operative,
post-operative and δ WOMAC scores. We found no relationship between pre-operative WOMAC scores and
one-year post-operative WOMAC or satisfaction scores, with Spearman’s
rank correlation coefficients of 0.16 and –0.05, respectively. The
ROC analysis showed areas under the curve (AUC) of 0.54 (pre-operative
WOMAC), 0.67 (post-operative WOMAC) and 0.43 (δ WOMAC), respectively,
for an improvement in satisfaction. We conclude that the pre-operative WOMAC score does not predict
the post-operative WOMAC score or patient satisfaction after THA,
and that WOMAC scores can therefore not be used to prioritise patient
care. Cite this article:
This study explores the relationship between
delay to surgical debridement and deep infection in a series of
364 consecutive patients with 459 open fractures treated at an academic
level one trauma hospital in North America. The mean delay to debridement for all fractures was 10.6 hours
(0.6 to 111.5). There were 46 deep infections (10%). There were
no infections among the 55 Gustilo-Anderson grade I open fractures.
Among the grade II and III injuries, a statistically significant
increase in the rate of deep infection was found for each hour of
delay (OR = 1.033: 95% CI 1.01 to 1.057). This relationship shows
a linear increase of 3% per hour of delay. No distinct time cut-off
points were identified. Deep infection was also associated with
tibial fractures (OR = 2.44: 95% CI 1.26 to 4.73), a higher Gustilo-Anderson
grade (OR = 1.99: 95% CI 1.004 to 3.954), and contamination of the
fracture (OR = 3.12: 95% CI 1.36 to 7.36). These individual effects
are additive, which suggests that delayed debridement will have
a clinically significant detrimental effect on more severe open
fractures. Delayed treatment appeared safe for grade 1 open fractures. However,
when the negative prognostic factors of tibial site, high grade
of fracture and/or contamination are present we recommend more urgent
operative debridement. Cite this article:
