Comparative Effectiveness Study

Abstract Objective To examine the associations between neuraxial anaesthesia or general anaesthesia and clinical outcomes, length of hospital stay, and readmission in adults undergoing lower limb revascularisation surgery. Design Comparative effectiveness study using linked, validated, population based databases. Setting Ontario, Canada, 1 April 2002 to 31 March 2015. Participants 20 988 patients Ontario residents aged 18 years or older who underwent their first lower limb revascularisation surgery in hospitals performing 50 or more of these surgeries annually. Main outcome measures Primary outcome was 30 day all cause mortality. Secondary outcomes were in-hospital cardiopulmonary and renal complications, length of hospital stay, and 30 day readmissions. Multivariable, mixed effects regression models, adjusting for patient, procedural, and hospital characteristics, were used to estimate associations between anaesthetic technique and outcomes. Robustness of analyses were evaluated by conducting instrumental variable, propensity score matched, and survival sensitivity analyses. Results Of 20 988 patients who underwent lower limb revascularisation surgery, 6453 (30.7%) received neuraxial anaesthesia and 14 535 (69.3%) received general anaesthesia. The percentage of neuraxial anaesthesia use ranged from 0.6% to 90.6% across included hospitals. Furthermore, use of neuraxial anaesthesia declined by 17% over the study period. Death within 30 days occurred in 204 (3.2%) patients who received neuraxial anaesthesia and 646 (4.4%) patients who received general anaesthesia. After multivariable, multilevel adjustment, use of neuraxial anaesthesia compared with use of general anaesthesia was associated with decreased 30 day mortality (absolute risk reduction 0.72%, 95% confidence interval 0.65% to 0.79%; odds ratio 0.68, 95% confidence interval 0.57 to 0.83; number needed to treat to prevent one death=139). A similar direction and magnitude of association was found in instrumental variable, propensity score matched, and survival analyses. Use of neuraxial anaesthesia compared with use of general anaesthesia was also associated with decreased in-hospital cardiopulmonary and renal complications (odds ratio 0.73, 0.63 to 0.85) and a reduced length of hospital stay (−0.5 days, −0.3 to−0.6 days). Conclusions Use of neuraxial anaesthesia compared with general anaesthesia for lower limb revascularisation surgery was associated with decreased 30 day mortality and hospital length of stay. These findings might have been related to reduced cardiopulmonary and renal complications after neuraxial anaesthesia and support the increased use of neuraxial anaesthesia in patients undergoing these surgeries until the results of a large, confirmatory randomised trial become available.

Statin Use

BACKGROUND Basic studies suggest that statins as add-on therapy may benefit patients with COVID-19; however, real-world evidence of such a beneficial association is lacking. OBJECTIVE We investigated differences in SARS-CoV-2 test positivity and clinical outcomes of COVID-19 (composite endpoint: admission to intensive care unit, invasive ventilation, or death) between statin users and nonusers. METHODS Two independent population-based cohorts were analyzed, and we investigated the differences in SARS-CoV-2 test positivity and severe clinical outcomes of COVID-19, such as admission to the intensive care unit, invasive ventilation, or death, between statin users and nonusers. One group comprised an unmatched cohort of 214,207 patients who underwent SARS-CoV-2 testing from the Global Research Collaboration Project (GRCP)-COVID cohort, and the other group comprised an unmatched cohort of 74,866 patients who underwent SARS-CoV-2 testing from the National Health Insurance Service (NHIS)-COVID cohort. RESULTS The GRCP-COVID cohort with propensity score matching had 29,701 statin users and 29,701 matched nonusers. The SARS-CoV-2 test positivity rate was not associated with statin use (statin users, 2.82% [837/29,701]; nonusers, 2.65% [787/29,701]; adjusted relative risk [aRR] 0.97; 95% CI 0.88-1.07). Among patients with confirmed COVID-19 in the GRCP-COVID cohort, 804 were statin users and 1573 were matched nonusers. Statin users were associated with a decreased likelihood of severe clinical outcomes (statin users, 3.98% [32/804]; nonusers, 5.40% [85/1573]; aRR 0.62; 95% CI 0.41-0.91) and length of hospital stay (statin users, 23.8 days; nonusers, 26.3 days; adjusted mean difference –2.87; 95% CI –5.68 to –0.93) than nonusers. The results of the NHIS-COVID cohort were similar to the primary results of the GRCP-COVID cohort. CONCLUSIONS Our findings indicate that prior statin use is related to a decreased risk of worsening clinical outcomes of COVID-19 and length of hospital stay but not to that of SARS-CoV-2 infection.

Although corticosteroids can serve as an effective anti-inflammatory adjuvant therapy, the role of adjunctive steroid therapy in pediatric bacterial meningitis in Taiwan remains under-investigated. Cases of acute bacterial meningitis, aged between 1 month and 20 years, were divided into a steroid group (empirical antibiotics with adjunctive steroid therapy) and a non-steroid group (empirical antibiotics only). Data were identified from the annual hospitalization discharge claims of the National Health Insurance Research Database using the International Classification of Diseases, Ninth Revision codes. Of the 8083 episodes enrolled in this study, 26% (2122/8083) and 74% (5961/8083) were divided into the steroid and non-steroid groups, respectively. The fatality rates were 7.9% in the steroid group and 1.7% in the non-steroid group during hospitalization (p < 0.0001). In the steroid and non-steroid groups, the median length of hospital stay was 13 and 6 days, respectively (p < 0.0001). Medical costs (median (interquartile range)) of hospitalization were 77,941 (26,647–237,540) and 26,653 (14,287–53,421) New Taiwan dollars in the steroid and non-steroid groups, respectively (p < 0.0001). The steroid group had a more fulminant course at baseline, a higher fatality rate, length of hospital stay, and medical cost of hospitalization. Therefore, the beneficial effects of the adjunctive use of corticosteroids in pediatric bacterial meningitis are inconclusive, and additional prospective multicenter investigations are required to clarify this issue.

Objective: To compare the, post op analgesia, vomiting, shivering, length of hospital stay, peri-operative haemodynamicchanges and recovery time in patient under going open cholecystectomy under general anaesthesia versus those receiving epiduralanaesthesia. Study design: Quasi experimental study. Place and duration of study: Combined Military Hospital Rawalpindi from 15 October2007 to 15 April 2008. Methodology: American Society of Anaesthesiology (ASA) physical status (PS) I and II patient of either genderundergoing un-complicated open cholecystectomy were randomly divided into two groups, group A (n=30) received general anaesthesia (GA)and group B (n=29) received thoracic epidural anaesthesia (EA). Patients of both the groups were assessed for peri-operative haemodynamicchanges, recovery time, post op analgesia, vomiting and length of hospital stay. Chi-square test was applied to compare the two groups andobtain P-value. P-value of less than 0.05 was considered significant. Results: 9 out of 30 patients (30%) of group “A” (general anaesthesia) and4 out of 29 patients (13.79%) in group “B” (epidural anaesthesia) had vomiting. Shivering was seen in 3 out of 30 (10%) in group “A” (generalanaesthesia) and 1 out of 29 (3.44%) patient in group “B” (epidural anaesthesia). Urinary retention was seen in 1 out of 30 (3.33%) in group “A”(general anaesthesia) and 8 out of 29 (27.5%) in group “B” (epidural anaesthesia). Urinary retention was relieved by psychotherapy. None ofthe patient required catheterization. Post operative recovery from surgery was determined by gastrointestinal motility (passage of flatus andstart of oral sips). In group “A” (general anaesthesia) 6 patients (20%) started oral sips in first post operative day, 16 patients (53.33%) onsecond post operative day, 8 patients (26.66%) in third post operative day. In the group “B” (epidural anaesthesia) 13 patients (44.8%) startedoral sips on first post operative day, 15 (51.72%) on second post operative day and one patient (3.44%) on third post operative day. Regardingthe length of hospital stay 17 patient (56.66%) of group “A” (general anaesthesia) were discharge by third post operative day and 22 patient(75.77) were discharge by third post operative day in group “B” (epidural anaesthesia). Conclusions: The use of intra-operative epiduralanaesthesia combined with postoperative epidural analgesia was found to be associated with reduction in the post operative pain and vomitingin patients under going open cholecystectomy.
