Impact of Acute Surgical Assessment Unit Dedicated Ultrasound Access at a Tertiary Care Hospital.

Cureus 2021 Aug 18;13(8):e17294. Epub 2021 Aug 18.

General Surgery, University Hospital Limerick, Limerick, IRL.

Background Delayed diagnosis, unnecessary hospital admissions and extended length of stay are the problems associated with inappropriate access to radiological investigations. The acute surgical assessment unit (ASAU) in Limerick has two dedicated ultrasound scan (USS) slots daily to overcome this problem. The aim of the current study was to investigate the clinical impact on patient care and the cost-effectiveness of such an ASAU USS access. Methods A retrospective review of all patients who underwent USS investigation in the ASAU between May and September 2017 was conducted. Demographic, referral source, presenting complaint, and clinical outcome data were obtained from the ASAU Log. USS data was obtained from the National Integrated Medical System (NIMIS). The Integrated Patient Management System (IPMS) and Therefore Case Manager, Therefore 2014(12.0.2) was utilized to check for any discharged ASAU patient re-presenting to the emergency department (ED) within 30 days.  Results A total of 102 patients underwent USS investigation during the study period. The most common presenting complaint was epigastric or right upper quadrant pain (55.8%). Eighty-six patients underwent USS on the same day and the majority (51%) were discharged home with appropriate outpatient follow-up. Approximately 26,000 Euros were saved over four months. Post-discharge ED visits in the ASAU discharged group was zero in the 30 days.  Conclusion The ASAU USS dedicated slots in University Hospital Limerick has had a significant positive impact on patient diagnostics, surgical admissions rates and streamlining resource allocation. Having dedicated slots for radiological investigations in the ASAU should become standard of care across all healthcare jurisdictions.

A Systematic Review and Meta-analysis of Thrombotic Events Following Endovenous Thermal Ablation of the Great Saphenous Vein.

Eur J Vasc Endovasc Surg 2018 09 9;56(3):410-424. Epub 2018 Jun 9.

Department of Vascular Surgery, University Hospital Limerick, St Nessan's Road, Limerick, Ireland; Munster Vascular, Cork, Limerick & Waterford, Ireland.

Objectives: A systematic review and meta-analysis was performed to determine the incidence of thrombotic events following great saphenous vein (GSV) endovenous thermal ablation (EVTA).

Methods: MEDLINE, Embase and conference abstracts were searched. Eligible studies were randomised controlled trials and case series that included at least 100 patients who underwent GSV EVTA (laser ablation or radiofrequency ablation [RFA]) with duplex ultrasound (DUS) within 30 days. The systematic review focused on the complications of endovenous heat induced thrombosis (EHIT), deep venous thrombosis (DVT), and pulmonary embolism (PE). The primary outcome for the meta-analysis was deep venous thrombotic events which were defined as DVT or EHIT Type 2, 3, or 4. Secondary outcomes for the meta-analysis were EHIT Type 2, 3, or 4, DVT and PE. Subgroup analyses were performed for both the RFA and EVLA groups. Pooled proportions were calculated using random effects modelling.

Results: Fifty-two studies (16,398 patients) were included. Thrombotic complications occurred infrequently. Deep venous thrombotic events occurred in 1.7% of cases (95% CI 0.9-2.7%) (25 studies; 10,012 patients; 274 events). EHIT Type 2, 3, or 4 occurred in 1.4% of cases (95% CI 0.8-2.3%) (26 studies; 10,225 patients; 249 events). DVT occurred in 0.3% of cases (95% CI = 0.2%-0.5%) (49 studies; 15,676 patients; 48 events). PE occurred in 0.1% of cases (95% CI = 0.1-0.2%) (29 studies; 8223 patients; 3 events). Similar results were found when the RFA and EVLA groups were analysed separately.

Conclusion: Thrombotic events occur infrequently following GSV EVTA. Given the large numbers of procedures worldwide and the potential for serious consequences, further research is needed on the burden of these complications and their management.

Use of Smart Toe(©) implant for small toe arthrodesis: A smart concept?

Foot Ankle Surg 2015 Jun 4;21(2):108-12. Epub 2014 Nov 4.

Regional Orthopaedic Hospital, Croom, Limerick, Ireland.

Background: Arthrodesis of small joints for hammer and claw toe deformities is a common forefoot operative procedure. Our objective was to review patients who underwent small toe arthrodesis with Smart Toe(©) intramedullary monobloc implant. Our aim was to assess patient's surgical outcome and to ascertain implant suitability.

Methods: This procedure was undertaken in 90 patients from February 2011 to December 2012. We present our review of 82 (91.1%) patients who attended the final six 6-month follow up. Mean age was 56.5 years. There were 7 (8.5%) males and 75 (8.5%) males and 75 (91.5%) females. Clinical and radiological evaluation was undertaken. A questionnaire was used to assess general symptoms, clinical outlook, deformity and patient's perceptions and acceptance. Foot and Ankle Outcome Score and Foot and Ankle Disability Index were used to judge outcome.

Results: There were 71 (86.6%) proximal and 11 (13.4%) distal interphalangeal joints with 69 (84.1%) second, 7 (8.5%) third, 6 (84.1%) second, 7 (8.5%) third, 6 (7.3%) fourth toes. There was persistent swelling in 7 (8.5%) and tenderness in 1 (1.2%). Appearance of toes was symmetrical in 71 (86.6%) and 11 (13.4%) were asymmetrical but asymptomatic. The mean range of movement of the adjacent joint was 53.9°. Control of toes was good in 72 (87.8%) patients. Mean percentage of improvement was 76.1% with 100% in 17 (20.7%) and over 80% in 47 (57.3%). Seventy (85.3%) would recommend and undergo repeat surgery. There were 2 (2.4%) cases of metal cut out. There was one (1.2%) implant failure. Union was achieved in 79 (96.3%) patients.

Conclusion: We feel that Smart Toe(©) small toe arthrodesis is a safe and reliable technique with good patient outcome and acceptance.

[Survey of patients at the preoperative evaluation clinic (PAC)].

Masui 2014 Feb;63(2):208-14

Department of Anesthesiology, Kyoto Prefectural University of Medicine, Kyoto 602-8566.

Anesthesia requires informed consent because it is an invasive procedure with high risks. We carried out a questionnaire study in 1,050 patients who were seen at the preoperative evaluation clinic (PAC). Patients who heard about PAC for the first time accounted for 77.9% in spite of having experienced anesthesia. Many patients were provided with the information about anesthesia the day before surgery and medication control and additional checking were difficult to carry out. Some patients (34.2%) were told about anesthesia with no attendant. In particular, about complications of anesthesia, many patients did not remember what the specific explanation had been offered in the past. We thought that it is necessary to explain the complications of anesthesia even if it is the second anesthesia for patients.
