Background: The purpose of this study was to provide a comprehensive assessment of the impact of the COVID-19 pandemic on the epidemiology of primary and revision arthroplasties of the hip and knee joint. Methods: This study compared the data on knee and hip arthroplasty procedures from 2 hospitals (primary and revision) conducted in two periods: the period of the COVID-19 pandemic in Poland (from 4 March 2020 to 15 October 2020) and the corresponding period prior to the pandemic (from 4 March 2019 to 15 October 2019). We compared the epidemiological data, demographic data, and hospital stay duration data from these two periods. Results: Our analysis demonstrated that the total number of hip arthroplasties conducted in 2020 decreased by 26% in comparison with 2019. In the case of knee arthroplasties, the total number of procedures in the evaluated period in 2020 decreased by 44%. Our study also showed that the mean time of hospital stay for orthopedic patients following hip or knee arthroplasty was 22.87% shorter. The female-to-male patient ratio decreased between the analyzed periods, and this was 22.96% lower during the pandemic. Conclusion: The COVID-19 pandemic in these two hospitals in Poland led to reduced numbers of hip and knee replacement procedures, shorter hospital stays, and a decreased female-to-male patient ratio. The mean age of patients undergoing hip or knee arthroplasty remained unchanged during the national lockdown with respect to the pre-pandemic figure.

The purpose of our study was to comprehensively assess the effect of the COVID-19 pandemic on knee and shoulder arthroscopy performed in an orthopedic department of a university hospital in Poland. This study compared the data on all shoulder and knee arthroscopy procedures performed in two different periods: The period of the COVID-19 pandemic in Poland (from March 4, 2020, to October 15, 2020) and the corresponding period prior to the pandemic (March 4, 2019, to October 15, 2019). The study evaluated epidemiological data, demographic data, and hospital stay duration. The total number of arthroscopy procedures conducted in the evaluated period in 2020 was approximately 8.6% higher than that in the corresponding 2019 period. The mean duration of hospital stay for orthopedic patients after their knee or shoulder arthroscopy was 3.1 days in 2020 and 2.8 days in 2019. Our study revealed the mean age of arthroscopy patients during the pandemic to be lower at 48.4 years than the 51.2 years recorded in 2019. The male-to-female ratio was shown to be lower at .85 during the pandemic, having decreased from 1.5 in 2019. The COVID-19 pandemic did not reduce the number of arthroscopy performed at our center, and the mean age of the patients did not change. However, the pandemic had a marked effect on the mean duration of hospital stay and male-to-female ratio.

Aims Elective orthopaedic services have had to adapt to significant system-wide pressures since the emergence of COVID-19 in December 2019. Length of stay is often recognized as a key marker of quality of care in patients undergoing arthroplasty. Expeditious discharge is key in establishing early rehabilitation and in reducing infection risk, both procedure-related and from COVID-19. The primary aim was to determine the effects of the COVID-19 pandemic length of stay following hip and knee arthroplasty at a high-volume, elective orthopaedic centre. Methods A retrospective cohort study was performed. Patients undergoing primary or revision hip or knee arthroplasty over a six-month period, from 1 July to 31 December 2020, were compared to the same period in 2019 before the COVID-19 pandemic. Demographic data, American Society of Anesthesiologists (ASA) grade, wait to surgery, COVID-19 status, and length of hospital stay were recorded. Results A total of 1,311 patients underwent hip or knee arthroplasty in the six-month period following recommencement of elective services in 2020 compared to 1,527 patients the year before. Waiting time to surgery increased in post-COVID-19 group (137 days vs 78; p < 0.001). Length of stay also significantly increased (0.49 days; p < 0.001) despite no difference in age or ASA grade. There were no cases of postoperative COVID-19 infection. Conclusion Time to surgery and length of hospital stay were significantly higher following recommencement of elective orthopaedic services in the latter part of 2020 in comparison to a similar patient cohort from the year before. Longer waiting times may have contributed to the clinical and radiological deterioration of arthritis and general musculoskeletal conditioning, which may in turn have affected immediate postoperative rehabilitation and mobilization, as well as increasing hospital stay.

Background/objective: Arthroscopic surgery in knee osteoarthritis is controversial with many studies refuting its efficacy in recent literature. This study aims to evaluate the mean duration to knee arthroplasty, and the effect of microfracture on the need for subsequent knee arthroplasty in patients above the age of 55 undergoing arthroscopic procedures for osteoarthritis. Methods: One hundred and nine consecutive patients with diagnosed osteoarthritis who underwent arthroscopic surgery performed from January 2000 to December 2012 on patients aged 55 years and above by a single surgeon were reviewed retrospectively. Demographic data, age at operation, comorbidities, perioperative details and information of subsequent total knee arthroplasty were collected and analysed. Results: There were 38 males and 71 females in our study group. The group was predominantly Chinese (51.38%), with hypertension and hyperlipidaemia being the most common comorbidities, each affecting 57.8% of our study cohort. All patients had a preoperative radiograph and a magnetic resonance imaging confirming the diagnosis of osteoarthritis associated with meniscal tears. Fifty-eight knees underwent microfracture along with arthroscopic meniscectomy. The mean follow-up duration was 127.5 months (10.5 years, range: 67–212 months). Twenty three patients (20.91%) underwent knee arthroplasties subsequently, with the mean duration to arthroplasty being 65.0 months (5.5 years, range: 7–166 months). The odds ratio of avoiding knee arthroplasty with microfracture was 1.03 (95% CI = 0.410–2.581). Conclusion: Arthroscopic procedures could possibly delay the need for subsequent knee arthroplasty for approximately 65 months in older patients with osteoarthritis. However, microfracture does not affect the duration between therapeutic arthroscopy and subsequent arthroplasty. Our long-term retrospective study provides an additional step in the understanding of the impact of arthroscopic procedures and a prospective case–control study would be an ideal follow-up to fully justify the application of arthroscopic procedures to delay knee arthroplasty.

Background Critically ill patients are at high risk for pressure ulcers. Successful prevention of pressure ulcers requires that caregivers have adequate knowledge of this complication. Objective To assess intensive care nurses’ knowledge of pressure ulcers and the impact of an educational program on knowledge levels. Methods A knowledge assessment test was developed. A cohort of registered nurses in a tertiary referral hospital in New Zealand had knowledge assessed 3 times: before an educational program, within 2 weeks after the program, and 20 weeks later. Multivariate analysis was performed to determine if attributes such as length of time since qualifying or level of intensive care unit experience were associated with test scores. The content and results of the assessment test were evaluated. Results Completion of the educational program resulted in improved levels of knowledge. Mean scores on the assessment test were 84% at baseline and 89% following the educational program. The mean baseline score did not differ significantly from the mean 20-week follow-up score of 85%. No association was detected between demographic data and test scores. Content validity and standard setting were verified by using a variety of methods. Conclusion Levels of knowledge to prevent and manage pressure ulcers were good initially and improved with an educational program, but soon returned to baseline.

This paper describes techniques to characterize the number of singletons in the setting of the generalized birthday problem, that is, the birthday problem in which the birthdays are non-uniformly distributed over the year. Approximations for the mean and variance presented which explicitly indicate the impact of the heterogeneity (expressed in terms of the Kullback–Leibler distance with respect to the homogeneous distribution). Then an iterative scheme is presented for determining the distribution of the number of singletons. The approximations are validated by experiments with demographic data.

787 Background: In most recent years, robotic assisted laparoscopic surgery (RALS) has proven to be a viable alternative to laparoscopic and traditional open surgery for colorectal cancer. Obtaining the adequate number of lymph nodes is not only essential for accurate staging, but also impacts both prognosis and the need for adjuvant chemotherapy. To date, the efficacy of lymph node harvest for RALS is not well studied or established. The aim of our study is to analyze the impact of RALS on lymphadenectomy for colorectal cancer. Methods: We performed a retrospective review of patients who underwent curative resections for colorectal cancer over a five-year period at a single institution by a single surgeon. Resections were classified as right-sided, sigmoid, or rectal, and subdivided into robotic and non-robotic surgery groups. The demographic data and histopathology were obtained, with an emphasis on the number lymph nodes harvested (LNH) during resections. Emergencies and non-curative resections were excluded. Results: Between January 2010 and December 2015, 136 patients with colorectal cancer underwent curative resections. Sixty-four underwent right-sided resections (28 laparoscopic, 36 robotic). Twenty-five underwent sigmoid resections (11 laparoscopic, 14 robotic), and 47 underwent rectal resections (15 open, 32 robotic). There was no significant difference in age, sex, BMI and ASA scores between the cohorts examined. The mean number of LNH with RALS was significantly higher in all three groups (right-sided—24 vs. 15 ( p= .0001), sigmoid—16 vs. 12 ( p= .046), rectal—19 vs. 4 ( p= .0016)). There was no difference in the rate of adequate lymph node extraction for staging purpose, i.e., 12 lymph nodes in all three groups. Conclusions: Robotic-assisted laparoscopic surgery is associated with a statistically significant increase in lymph node harvest for right-sided, sigmoid and rectal resections for malignancy. Future studies with larger sample sizes are necessary to validate these findings.

Purpose. To compare the operating time, amount of blood transfused, length of hospital stay, and early complications (within 6 months) between 2-week staged bilateral arthroplasties and matched randomised controls undergoing unilateral arthroplasties. Methods. From October 1992 to October 2000, 90 patients who underwent bilateral hip or knee arthroplasties with a 2-week interval were compared with matched randomised controls undergoing unilateral arthroplasties. A single surgeon performed all procedures. Results. After the match-up process, 30 pairs of patients were included in the analysis. There were no significant differences in the operating times, amount of blood transfused, and early complication rates. The mean difference in length of hospital stay was significant ( t= −3.552, df=29, p<0.001). Conclusion. Compared to staged procedures with an interval months apart, staged sequential arthroplasty with a 7- to 10-day interval during one hospital admission is more efficient, as it facilitates earlier rehabilitation without higher complication rates, and entails shorter hospital stays.

Aim. To assess the degree of satisfaction among hemodialysis patients and the factors influencing this satisfaction.Methods. Patients were recruited from 3 Saudi dialysis centers. Demographic data was collected. Using 1 to 10 Likert scale, the patients were asked to rate theoverall satisfactionwith, andthe overall impactof, their dialysis therapy on their lives and to rate the effect of the dialysis therapy on 15 qualities of life domains.Results. 322 patients were recruited (72.6% of the total eligible patients). The mean age was 51.7 years (15.4); 58% have been on dialysis for 3 years. The mean Charlson Comorbidity Index was 3.2 (2), and Kt/V was 1.3 (0.44). The mean satisfaction score was (7.41 2.75) and the mean score of the impact of the dialysis on the patients' lives was 5.32 2.55. Male patients reported worse effect of dialysis on family life, social life, energy, and appetite. Longer period since the commencement of dialysis was associated with adverse effect on finances and energy. Lower level of education was associated with worse dialysis effect on stress, overall health, sexual life, hobbies, and exercise ability.Conclusion. The level of satisfaction is affected by gender, duration on dialysis, educational level, and standard of care given.

AbstractThis study investigated the impact of bronchiectasis on patients admitted to the intensive care unit (ICU) at a hospital in Korea. Patients with bronchiectasis were diagnosed using results of chest computed tomography performed before ICU admission. The severity of bronchiectasis was based on the number of affected lobes, and patients with ≥ 3 bronchiectatic lobes were classified into the severe bronchiectasis group. Overall, 823 patients were enrolled. The mean age was 66.0 ± 13.9 years, and 63.4% were men. Bronchiectasis and severe bronchiectasis were present in 148 (18.0%) and 108 (13.1%) patients, respectively. The increase in the number of bronchiectatic lobes was related to the rise in ICU mortality (P for trend = 0.012) and in-hospital mortality (P for trend = 0.004). Patients with severe bronchiectasis had higher odds for 28-day mortality [odds ratio (OR) 1.122, 95% confidence interval (CI) 1.024–1.230], ICU mortality (OR 1.119, 95% CI 1.023–1.223), and in-hospital mortality (OR 1.208, 95% CI 1.092–1.337). The severe bronchiectasis group showed lower overall survival (log-rank P < 0.001), and the adjusted hazard ratio was 1.535 (95% CI 1.178–2.001). Severe bronchiectasis had a negative impact on all-cause mortality during ICU and hospital stays, resulting in a lower survival rate.
