To investigate the experience and emotional impact of prosthetic joint infection (PJI) on orthopaedic surgeons and identify holistic strategies to improve the management of PJI and protect surgeons’ wellbeing. In total, 18 prosthetic joint surgeons in Sweden were recruited using a purposive sampling strategy. Content analysis was performed on transcripts of individual in-person interviews conducted between December 2017 and February 2018.Aims
Methods
The aims of this study were to determine the indications and
frequency of ordering a CT pulmonary angiography (CTPA) following
primary arthroplasty of the hip and knee, and to determine the number
of positive scans in these patients, the location of emboli and
the outcome for patients undergoing CTPA. We analyzed the use of CTPA, as an inpatient and up to 90 days
as an outpatient, in a cohort of patients and reviewed the medical
records and imaging for each patient undergoing CTPA.Aims
Patients and Methods
To investigate whether elective joint arthroplasty performed
at the weekend is associated with a different 30-day mortality We examined the 30-day cumulative mortality rate (Kaplan-Meier)
for all elective hip and knee arthroplasties performed in England
and Wales between 1st April 2003 and 31st December 2014, comprising
118 096 episodes undertaken at the weekend and 1 233 882 episodes
performed on a weekday. We used Cox proportional-hazards regression
models to assess for time-dependent variation and adjusted for identified
risk factors for mortality.Aims
Patients and Methods
In our department we use an enhanced recovery
protocol for joint replacement of the lower limb. This incorporates the
use of intravenous tranexamic acid (IVTA; 15 mg/kg) at the induction
of anaesthesia. Recently there was a national shortage of IVTA for
18 weeks; during this period all patients received an oral preparation
of tranexamic acid (OTA; 25 mg/kg). This retrospective study compares
the safety (surgical and medical complications) and efficacy (reduction
of transfusion requirements) of OTA and IVTA. During the study period
a total of 2698 patients received IVTA and 302 received OTA. After
adjusting for a range of patient and surgical factors, the odds
ratio (OR) of receiving a blood transfusion was significantly higher
with IVTA than with OTA (OR 0.48 (95% confidence interval 0.26 to
0.89), p = 0.019), whereas the safety profile was similar, based
on length of stay, rate of readmission, return to theatre, deep
infection, stroke, gastrointestinal bleeding, myocardial infarction,
pneumonia, deep-vein thrombosis and pulmonary embolism. The financial
benefit of OTA is £2.04 for a 70 kg patient; this is amplified when
the cost saving associated with significantly fewer blood transfusions
is considered. Although the number of patients in the study is modest, this
work supports the use of OTA, and we recommend that a randomised
trial be undertaken to compare the different methods of administering
tranexamic acid. Cite this article:
We examined the risk of thrombotic and major
bleeding events in patients undergoing total hip and knee replacement
(THR and TKR) treated with thromboprophylaxis, using nationwide
population-based databases. We identified 83 756 primary procedures
performed between 1997 and 2011. The outcomes were symptomatic venous thromboembolism
(VTE), myocardial infarction (MI), stroke, death and major bleeding
requiring hospitalisation within 90 days of surgery. A total of 1114 (1.3%) and 483 (0.6%) patients experienced VTE
and bleeding, respectively. The annual risk of VTE varied between
0.9% and 1.6%, and of bleeding between 0.4% and 0.8%. The risk of
VTE and bleeding was unchanged over a 15-year period. A total of
0.7% of patients died within 90 days, with a decrease from 1% in
1997 to 0.6% in 2011 (p <
0.001). A high level of comorbidity
and general anaesthesia were strong risk factors for both VTE and
bleeding, with no difference between THR and TKR patients. The risk
of both MI and stroke was 0.5%, which remained unchanged during
the study period. In this cohort study of patients undergoing THR and TKR patients
in routine clinical practice, approximately 3% experienced VTE,
MI, stroke or bleeding. These risks did not decline during the 15-year
study period, but the risk of dying fell substantially. Cite this article:
Using the General Practice Research Database, we examined the temporal changes in the rates of primary total hip (THR) and total knee (TKR) replacement, the age at operation and the female-to-male ratio between 1991 and 2006 in the United Kingdom. We identified 27 113 patients with THR and 23 843 with TKR. The rate of performance of THR and TKR had increased significantly (p <
0.0001 for both) during the 16-year period and was greater for TKR, especially in the last five years. The mean age at operation was greater for women than for men and had remained stable throughout the period of study. The female-to-male ratio was higher for THR and TKR and had remained stable. The data support the notion that the rate of joint replacement is increasing in the United Kingdom with the rate of TKR rising at the highest rate. The perception that the mean age for TKR has decreased over time is not supported.
