A Detailed Cost and Efficiency Analysis of Performing Carpal Tunnel Surgery in the Main Operating Room versus the Ambulatory Setting in Canada

Abstract

Background Our goals were to analyze cost and efficiency of performing carpal tunnel release (CTR) in the main operating room (OR) versus the ambulatory setting, and to document the venue of carpal tunnel surgery practices by plastic surgeons in Canada. Method A detailed analysis of the salaries of nonphysician personnel and materials involved in CTR performed in these settings was tabulated. Hospital statistical records were used to calculate our efficiency analysis. A survey of practicing plastic surgeons in Canada documented the venue of CTR performed by most. Results In a 3-h surgical block, we are able to perform nine CTRs in the ambulatory setting versus four in the main OR. The cost of CTR in the ambulatory setting is $36/case and $137/case in the main OR in the same hospital. Only 18% of Canadian respondents use the main OR exclusively for CTR, whereas 63% use it for some of their cases. The ambulatory setting is used exclusively by 37%, whereas 69% use it for greater than 95% of their cases. The majority of CTR cases (>95%) are done without an anesthesia provider by 73% of surgeons. Forty-three percent use epinephrine routinely with local anesthesia and 43% avoid the use of a tourniquet for at least some cases by using epinephrine for hemostasis. Conclusion The use of the main OR for CTR is almost four times as expensive, and less than half as efficient as in an ambulatory setting. In spite of this, many surgeons in Canada continue to use the more expensive, less efficient venue of the main OR for CTR.

Use of WALLANT technique in hand surgery, safe and advantageous. Personal experience

“…This local anesthesia technique that uses 1% lidocaine with 1:100,000 epinephrine has the advantage of avoiding the risks associated with locoregional anesthesia, avoiding the use of sedation and, in fact, of its toxicity, of which the anesthesiologists say "the best sedation is no sedation". The cost of preoperative preparation decreases substantially as no preanesthetic assessment is required when using locoregional anesthesia (axillary, infraclavicular blocks) (13). The fact that this type of anesthesia avoids the use of tourniquet has several advantages: absence of pain or discomfort associated with tourniquets, a more comfortable position on the operating table and adaptable in case of patients with articular rheumatic diseases who do not tolerate certain positions on the operating table, avoidance of bleeding after tourniquet deflation (14,15).…”

The wide-awake approach to ulnar nerve entrapment: results of an integrated one-stop wide-awake surgical pathway

“…The wide awake hand surgery techniques we utilize enable optimisation of patient pathways. Through the wide awake approach, patients can be safely and effectively treated in one management stop 1 and outside the main operating theatre [5][6][7] .…”

Peripheral Nerve Entrapment and their Surgical Treatment

“…The surgical procedure entails complete transverse carpal ligament section to decompress the MN. Local, regional or general anaesthesia are options, but local is faster and more cost effective [50,51]. Open field (Figures 1F and G) or endoscopy has a similar time out of work, but the latter MN damage is more frequent [52][53][54].…”
