They were able to show that bracing is effective in decreasing the progression of high-risk [ 5] curves to the threshold for surgery.
In addition, the changes in patient comorbidity profiles (eg, increased proportion of knee arthroplasty patients with diabetes and obesity over time) and indications for surgery (eg, lower threshold for surgery) may in part explain our findings.
In addition, the changes in patient co-morbidity profiles (for example, increased proportion of THA in patients with diabetes and obesity over time) and indications for surgery (e.g. lower threshold for surgery) may in part explain our findings.
The increase in rehospitalization rate following knee replacement surgery seen over the last decade in Denmark could be due to changes in patient comorbidity profiles and threshold for surgery, as discussed above.
The availability of diagnostic modalities such as computed tomography, with 100% sensitivity and 95% specificity, 34 35 combined with the low morbidity associated with laparoscopy, 36 37 has increased the diagnostic accuracy for appendicitis and reduced the threshold for surgery for appendicitis that may have resolved spontaneously.
Furthermore, most of those clinically relevant aneurysms additionally detected were smaller than the threshold for surgery referral; of 1851 men referred to rescreening, 31 and 50 were referred to elective surgery as a consequence of rescreening once or for life, respectively.
Over the four month assessment period, 287 patients were seen in the clinic who had a preliminary diagnosis of carotid stenosis which met the threshold for surgery (greater than 70% blockage), and had a recent ultrasound confirming the degree of stenosis, so were potentially eligible for CARAT.
In a recent study, Weinstein et al. [ 18] confirmed that bracing significantly decreased the progression of high-risk curves to the threshold for surgery and that the success rate was higher in patients that had worn the brace for more hours.
As such, this study seeks to explore visual impairment thresholds for cataract surgery and levels of improvement seen following cataract surgery in Canada.
