Abstract
BACKGROUND AND AIM The coronavirus disease 2019 (COVID-19) outbreak deeply affected intensive care units (ICUs). We aimed to explore the main changes in the distribution and characteristics of Swiss ICU patients during the first two COVID-19 waves and to relate these figures with those of the preceding two years. METHODS Using the national ICU registry, we conducted an exploratory study to assess the number of ICU admissions in Switzerland and their changes over time, characteristics of the admissions, the length of stay (LOS) and its trend over time, ICU mortality and changes in therapeutic nursing workload and hospital resources in 2020 and compare them with the average figures in 2018 and 2019. RESULTS After analysing 242,935 patient records from all 84 certified Swiss ICUs, we found a significant decrease in admissions (-9.6%, corresponding to -8005 patients) in 2020 compared to 2018/2019, with an increase in the proportion of men admitted (61.3% vs 59.6%; p <0.001). This reduction occurred in all Swiss regions except Ticino. Planned admissions decreased from 25,020 to 22,021 in 2020 and mainly affected the neurological/neurosurgical (-14.9%), gastrointestinal (-13.9%) and cardiovascular (-9.3%) pathologies. Unplanned admissions due to respiratory diagnoses increased by 1971 (+25.2%), and those of patients with acute respiratory distress syndrome (ARDS) requiring isolation reached 9973 (+109.9%). The LOS increased by 20.8% from 2.55 ± 4.92 days (median 1.05) in 2018/2019 to 3.08 ± 5.87 days (median 1.11 days; p <0.001), resulting in an additional 19,753 inpatient days. The nine equivalents of nursing manpower use score (NEMS) of the first nursing shift (21.6 ± 9.0 vs 20.8 ± 9.4; p <0.001), the total NEMS per patient (251.0 ± 526.8 vs 198.9 ± 413.8; p <0.01) and mortality (5.7% vs 4.7%; p <0.001) increased in 2020. The number of ICU beds increased from 979 to 1012 (+3.4%), as did the number of beds equipped with mechanical ventilators (from 773 to 821; +6.2%). CONCLUSIONS Based on a comprehensive national data set, our report describes the profound changes triggered by COVID-19 over one year in Swiss ICUs. We observed an overall decrease in admissions and a shift in admission types, with fewer planned hospitalisations, suggesting the loss of approximately 3000 elective interventions. We found a substantial increase in unplanned admissions due to respiratory diagnoses, a doubling of ARDS cases requiring isolation, an increase in ICU LOS associated with substantial nationwide growth in ICU days, an augmented need for life-sustaining therapies and specific therapeutic resources and worse outcomes.

Switching from robotic-assisted extended transabdominal preperitoneal (eTAPP) to totally extraperitoneal (eTEP) hernia repair for umbilical and epigastric hernias. Sci Rep 2024; 14:1800. [PMID: 38245577 PMCID: PMC10799892 DOI: 10.1038/s41598-024-52165-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Accepted: 01/15/2024] [Indexed: 01/22/2024] Open
Abstract
Our study aimed to assess the safety and effectiveness of the robotic-assisted extended totally extraperitoneal (eTEP) repair compared to transabdominal preperitoneal (eTAPP) repair with a suprapubic trocar insertion to treat umbilical and epigastric hernias. On a prospectively maintained database, we identified patients who underwent either eTEP or eTAPP for treating umbilical and epigastric hernias. During the study period, 53 patients were included, 32 in the eTEP group and 21 in the eTAPP group. The mean age was 59.0 ± 13.9 years, 45 patients (84.9%) were male, and the mean BMI was 28.0 ± 5.9 kg/m2. Most hernias were umbilical (81.1%) and primary (83.0%). The operative time for eTEP was slightly shorter than for eTAPP (106 ± 43 min vs. 126 ± 74 min, p = 0.232). Postoperatively, only one case of bleeding and one seroma were recorded. No complication occurred during a mean follow-up of 11.3 ± 6.4 months in the eTEP group and 20.5 ± 9.7 months in the eTAPP group. In conclusion, our study showed that the eTEP with suprapubic approach was safe and feasible in the treatment of epigastric and umbilical hernias. According to our experience, shorter operative time, integrity of the posterior layers and increased overlap size are the main surgical reasons of switching from eTAPP to eTEP.

Long-Term Evolution of Activities of Daily Life (ADLs) in Critically Ill COVID-19 Patients, a Case Series. Healthcare (Basel) 2023; 11:healthcare11050650. [PMID: 36900655 PMCID: PMC10001119 DOI: 10.3390/healthcare11050650] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 02/16/2023] [Accepted: 02/19/2023] [Indexed: 02/25/2023] Open
Abstract
BACKGROUND The most common long-term symptoms of critically ill COVID-19 patients are fatigue, dyspnea and mental confusion. Adequate monitoring of long-term morbidity, mainly analyzing the activities of daily life (ADLs), allows better patient management after hospital discharge. The aim was to report long-term ADL evolution in critically ill COVID-19 patients admitted to a COVID-19 center in Lugano (Switzerland). METHODS A retrospective analysis on consecutive patients discharged alive from ICU with COVID-19 ARDS was performed based on a follow-up one year after hospital discharge; ADLs were assessed through the Barthel index (BI) and the Karnofsky Performance Status (KPS) scale. The primary objective was to assess differences in ADLs at hospital discharge (acute ADLs) and one-year follow-up (chronic ADLs). The secondary objective was to explore any correlations between ADLs and multiple measures at admission and during the ICU stay. RESULTS A total of 38 consecutive patients were admitted to the ICU; a t-test analysis between acute and chronic ADLs through BI showed a significant improvement at one year post discharge (t = -5.211, p < 0.0001); similarly, every single task of BI showed the same results (p < 0.0001 for each task of BI). The mean KPS was 86.47 (SD 20.9) at hospital discharge and 99.6 at 1 year post discharge (p = 0.02). Thirteen (34%) patients deceased during the first 28 days in the ICU; no patient died after hospital discharge. CONCLUSIONS Based on BI and KPS, patients reached complete functional recovery of ADLs one year after critical COVID-19.

Abstract
Background There is a paucity of data about the occurrence and risk factors of herpes simplex virus (HSV) reactivation among patients with severe COVID-19 presenting with acute respiratory distress syndrome (ARDS). Methods We performed a nested case-control study among a cohort of SARS-CoV-2 infected patients with ARDS. Between March and April 2020, all consecutive mechanically ventilated patients ≥18 years old with a positive PCR for SARS-CoV-2 on mucocutaneous samples were included in the study. We collected data on demographics, medical history, laboratory variables, administration of antivirals and other agents, respiratory and organ support procedures, microbiological results, and management of ARDS with prone positioning and the use of steroids. Univariate and multivariable Cox regression models were performed in order to identify predictors of HSV reactivation. Results Eighty-three patients with laboratory-confirmed SARS-CoV-2 infection were admitted to the ICU for mechanical ventilation. 18/83 (21.7%) patients developed mucocutaneous herpes simplex virus reactivation after a median of 17 days (IQR, 14–20). Prone positioning was the only independent risk factor for HSV reactivation (adj. hazard ratios, 1.60; 95% CI, 1.11–2.30; P = 0.009). All patients with mucocutaneous HSV reactivation were treated with antivirals. The outcome in terms of ventilator-associated pneumonia, catheter-related bloodstream infections, and in-hospital mortality was similar for patients with and without HSV reactivation. Conclusions HSV reactivation is frequent in COVID-19 patients with ARDS, especially if prolonged invasive mechanical ventilation with prone positioning is needed. Prompt testing for HSV and initiation of antiviral therapy should be performed in case of mucocutaneous lesions in this population.

Abstract
BACKGROUND The majority of prevalence studies on deep vein thrombosis (DVT) in severe COVID-19 patients are retrospective with DVT assessment based on clinical suspicion. Our aim was to prospectively and systematically estimate the occurrence of DVT in critically-ill mechanically-ventilated patients, and to identify potential risk factors for DVT occurrence and mortality. METHODS All patients with COVID-19 admitted to our 45 beds in the Intensive Care Unit (ICU) between March 6, 2020, and April 18, 2020, requiring invasive ventilatory support were daily screened for DVT with lower extremities and jugular veins ultrasonography. Univariate and multivariable logistic regression models were performed in order to identify predictors of DVT and mortality. RESULTS Seventy-six patients were included in the final analysis (56 men, mean age 67 years, median SOFA=7 points, median SAPS II=41 points, median PaO<inf>2</inf>/Fi0<inf>2</inf>=10.8 kPa). The period prevalence of DVT was 40.8%. Thirty-one DVTs were diagnosed. Twenty-five DVTs (80.6% of total DVTs) were catheter-related, mainly in the jugular veins. Twenty-six DVTs (83.9%) occurred in patients receiving enhanced antithrombotic prophylaxis. No independent variable was predictive of DVT occurrence. Twenty-eight patients (36.8%) died during the ICU stay. Age and SOFA score were independently associated with mortality. CONCLUSIONS A high number of critically-ill mechanically-ventilated COVID-19 patients developed a DVT. The majority of DVTs were catheter-related and occurred under intensive prophylactic anticoagulation. Routine ultrasound of the jugular veins should be suggested in this patient population, and in particular in presence of a central venous catheter.

Effect of postoperative haemoglobin variation on major cardiopulmonary complications in high cardiac risk patients undergoing anatomical lung resections. Interact Cardiovasc Thorac Surg 2019; 29:883-889. [PMID: 31408170 DOI: 10.1093/icvts/ivz199] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2019] [Revised: 06/28/2019] [Accepted: 07/10/2019] [Indexed: 11/12/2022] Open
Abstract
OBJECTIVES Recent evidence shows that permissive anaemia strategies are safe in different surgical settings. However, effects of variations in haemoglobin (Hb) levels could have a negative impact in high-risk patients. We investigated the combined effect of postoperative Hb concentration and cardiac risk status on major cardiopulmonary complications after anatomical lung resections. METHODS We retrospectively analysed the records, collected in a prospective clinical database, of 154 consecutive patients undergoing anatomical lung resections at our institution (February 2017-February 2019). Hb levels were displayed as preoperative concentration, nadir Hb level before onset of complications and delta Hb (ΔHb). Cardiac risk was stratified according to the Thoracic Revised Cardiac Risk Index (ThRCRI). Univariable and multivariable logistic regression analyses were used to test the associations between patients, surgical variables and cardiopulmonary complications according to the European Society of Thoracic Surgeons definitions. RESULTS Cardiopulmonary complications occurred in 63 patients (17%). In the fully adjusted multivariable model, higher values of ΔHb were associated with increased risk of complications [odds ratio (OR) 1.07; P < 0.001], along with higher ThRCRI classes (classes A-B versus C-D: OR 0.09; P < 0.001). Interaction terms with transfusion were not statistically significant, indicating that the harmful effect of ΔHb was independent. According to receiver operating characteristic curve analysis, a ΔHb of 29 g/l was found to be the best cut-off value for predicting complications. CONCLUSIONS In our series, ΔHb, rather than nadir Hb, was associated with an increased risk of complications, particularly in patients with higher cardiac risk. Restrictive transfusion strategies should be carefully applied in patients undergoing lung resections and balanced according to individual clinical status.

Abstract
BACKGROUND Family satisfaction of critically ill patients has gained increased interest as important indicator to evaluate the quality of care in the intensive care unit (ICU). The family satisfaction in the ICU questionnaire (FS-ICU 24) is a well-established tool to assess satisfaction in such settings. We tested the hypothesis that an intervention, aiming at improved communication between health professionals and patients' next of kin in the ICU improves family satisfaction, as assessed by FS-ICU 24. METHODS Using a multicenter before-and-after study design, we evaluated medium-term effectiveness of VALUE, a recently proposed strategy aiming at improved communication. Satisfaction was assessed using the FS-ICU 24 questionnaire. Performance-importance plots were generated in order to identify items highly correlated with overall satisfaction but with low individual score. RESULTS A total of 163 completed family questionnaires in the pre-intervention and 118 in the post-intervention period were analyzed. Following the intervention, we observed: (1) a non-significant increase in family satisfaction summary score and sub-scores; (2) no decline in any individual family satisfaction item, and (3) improvement in items with high overall impact on satisfaction but quoted with low degree of satisfaction. CONCLUSION No significant improvement in family satisfaction of critically ill adult patients could be found after implementing the VALUE strategy. Whether these results are due to insufficient training of the new strategy or a missing effect of the strategy in our socio-economic environment remains to be shown.

Abstract
OBJECTIVE The first description of the simplified acute physiology score (SAPS) II dates back to 1993, but little is known about its accuracy in daily practice. Our purpose was to evaluate the accuracy of scoring and the factors that affect it in a nationwide survey. METHODS Twenty clinical scenarios, covering a broad range of illness severities, were randomly assigned to a convenience sample of physicians or nurses in Swiss adult intensive care units (ICUs), who were asked to assess the SAPS II score for a single scenario. These data were compared to a reference that was defined by five experienced researchers. The results were cross-matched with demographic characteristics and data on the training and quality control for the scoring, structural and organisational properties of each participating ICU. RESULTS A total of 345 caregivers from 53 adult ICU providers completed the SAPS II evaluation of one clinical scenario. The mean SAPS II scoring was 42.6 ± 23.4, with a bias of +5.74 (95%CI 2.0-9.5) compared to the reference score. There was no evidence of bias variation according to the case severity, ICU size, linguistic area, profession (physician vs. nurse), experience, initial SAPS II training, or presence of a quality control system. CONCLUSION This nationwide survey revealed substantial variability in the SAPS II scoring results. On average, SAPS II scoring was overestimated by more than 13%, irrespective of the profession or experience of the scorer or of the structural characteristics of the ICUs.

Abstract
Aim To identify predictors of bacteremia in critically ill patients, to evaluate the impact of blood cultures on the outcome, and to define conditions for breakthrough bacteremia despite concurrent antibiotic treatment. Methods A descriptive retrospective study was performed over a two-year period (2007-2008) in the medico-surgical Intensive Care Unit (ICU) of the San Giovanni Hospital in Bellinzona, Switzerland. Results Forty-five out of 231 patients (19.5%) had positive blood cultures. Predictors of positive blood cultures were elevated procalcitonin levels (>2 µg/L, P < 0.001), higher severity scores (Simplified Acute Physiology Score II>43, P = 0.014; Sequential Organ Failure Assessment >4.0, P < 0.001), and liver failure (P = 0.028). Patients with bacteremia had longer hospital stays (31 vs 21 days, P = 0.058), but their mortality was not different from patients without bacteremia. Fever (t > 38.5°C) only showed a trend toward a higher rate of blood culture positivity (P = 0.053). The rate of positive blood cultures was not affected by concurrent antibiotic therapy. Conclusions The prediction of positive blood culture results still remains a very difficult task. In our analysis, blood cultures were positive in 20% of ICU patients whose blood was cultured, and positive findings increased with elevated procalcitonin levels, liver failure, and higher severity scores. Blood cultures drawn >4 days after the start of antibiotic therapy and >5 days after surgery could detect pathogens responsible for a new infection complication.

Abstract
PRINCIPLES The nine equivalents of nursing manpower use score (NEMS) is frequently used to quantify, evaluate and allocate nursing workload at intensive care unit level. In Switzerland it has also become a key component in defining the degree of ICU hospital reimbursement. The accuracy of nurse registered NEMS scores in real life was assessed and error-prone variables were identified. METHODS In this retrospective multicentre audit three reviewers (1 nurse, 2 intensivists) independently reassessed a total of 529 NEMS scores. Correlation and agreement of the sum-scores and of the different variables among reviewers, as well as between nurses and the reviewers' reference value, were assessed (ICC, % agreement and kappa). Bland & Altman (reference value - nurses) of sum-scores and regression of the difference were determined and a logistic regression model identifying risk factors for erroneous assessments was calculated. RESULTS Agreement for sum-scores among reviewers was almost perfect (mean ICC = 0.99 / significant correlation p <0.0001). The nurse registered NEMS score (mean ± SD) was 24.8 ± 8.6 points versus 24.0 ± 8.6 points (p <0.13 for difference) of the reference value, with a slightly lower ICC (0.83). The lowest agreement was found in intravenous medication (0.85). Bland & Altman was 0.84 ± 10, with a significant regression between the difference and the reference value, indicating overall an overestimation of lower scores (≤29 points) and underestimation of higher scores. Accuracy of scores or variables was not associated with nurses' characteristics. CONCLUSIONS In real life, nurse registered NEMS scores are highly accurate. Lower (≤29 points) NEMS sum-scores are overestimated and higher underestimated. Accuracy of scores or variables was not associated with nurses' characteristics.

Abstract
BACKGROUND Secondary prevention of coronary artery disease is highly effective and implemented on a large scale. However, studies testing adherence to recommended secondary prevention of other vascular diseases are rare. Our goal was to evaluate whether the kind of vascular disease influences prescription practice of secondary drug prophylaxis at hospital discharge and to which extent secondary prevention is actually complete. METHODS A 3-month prospective observational review of the hospital discharge information of all patients hospitalized because of a vascular disease diagnosis: coronary artery disease (i.e. acute myocardial infarction [AMI] and chronic stable angina [CSA]); peripheral artery disease [PAD] and cerebrovascular disease [CVD]. The analysis was done by board registered internists with a structured form that founded on internationally accepted recommendations. RESULTS From 271 patients 191 had coronary artery disease (105 AMI and 86 CSA), 88 PAD and 72 CVD. Global prescription rate (mean; 95% CI) of indicated secondary prophylaxis drugs was 74.1% (69.9-78.2) for AMI, 72.4% (67.2-77.5) for CSA, 74.7% (68.8-80.7) for PAD and 72.1% (66.9-77.3) for CVD. The proportion of patients who were prescribed a complete bundle of recommended medications was globally 29.5% (24.1-35.0). CONCLUSIONS We found similar global prescription rates of secondary prevention for the different vascular diseases. However, only one third of the studied collective gets a complete set of required prophylactic drugs.

Abstract
BACKGROUND Limited information exists in regard to drug omissions and unjustified medications in the hospital discharge summary (DS). OBJECTIVE To evaluate the incidence and types of drug omissions and unjustified medications in the DS, and to assess their potential impact on patient health. METHODS A prospective observational review of the DSs of all patients discharged from our Internal Medicine Department over a 3-month period. Data assessment was made by internists using a structured form. RESULTS Of the 577 evaluated DSs, 66% contained at least one inconsistency accounting for a total of 1012 irregularities. There were 393 drug omissions affecting 251 patients, 32% of which were potentially harmful. Seventeen per cent of all medications (619/3691) were unjustified, affecting 318 patients. The unjustified medication was potentially harmful in 16% of cases, occurred significantly more frequent in women than in men (61% vs 50%; p = 0.008) and increased linearly with the number of drugs prescribed (p<0.001). Drug omission had a twofold higher potential to cause harm than unjustified medication. CONCLUSIONS Drug omissions and unjustified medications are frequent, and systemic changes are required to substantially reduce these inconsistencies.

Abstract
Tumour lysis syndrome (TLS) is a constellation of meta- bolic complications due to the rapid destruction of malignant cells, causing renal, cardiac or cerebral dysfunction. Electrolyte abnormalities include hyperuricaemia, hyperphosphataemia, hyperkalaemia and hypocalcaemia. TLS-induced renal failure is mainly caused by uric acid and calcium phosphate crystal deposition and usually develops following cytotoxic chemotherapy. Here, we present a case of spontaneous TLS in a patient with chronic myelomonocytic leukaemia (CMML) with massive uric acid stone and crystal formation and rapidly worsening renal failure. Autopsy revealed underlying tumourous kidney infiltration. Risk factors for occurrence of TLS and current therapeutic management are discussed.

Abstract
Critically ill patients commonly show a decrease in hemoglobin concentration during their stay in the intensive care unit. The purpose of the present study was to evaluate whether nonbleeding patients with acute coronary syndrome (ACS) show a similar decrease of hemoglobin, and thereby furnish reference values and analyze possible mechanisms. In this retrospective, descriptive study, the charts of all patients with ACS hospitalized between January 2004 and September 2005 were screened with regard to patient characteristics, time course of hemoglobin, as well as clinical parameters, concomitant drug therapy, and fluid balances. One hundred three nonbleeding patients with ACS were analyzed. They showed an average hemoglobin decrease of 1.27 +/- 1.00 g/dl (p <0.001). The decrease in hemoglobin level was observed during the first 12 to 24 hours; thereafter the hemoglobin concentration remained stable. We found a correlation among decrease of hemoglobin, parameters of stress, such as hypertension (p = 0.019), tachycardia (p = 0.004), pain (p = 0.043), and white blood cells (p = 0.021), as well as the intravenous administration of nitroglycerin (p = 0.004). In conclusion, during the first 24 hours in the intensive care unit the hemoglobin concentration of nonbleeding patients with ACS regularly decreases at 1.27 +/- 1.00 g/dl. Any further decrease in hemoglobin level beyond these values should entail early active search of the bleeding source. We hypothesize that this decrease is due to normalization of the previous stress-induced hemoconcentration and "internal hemodilution" by nitroglycerin.

Abstract
We present the case of a 74-years old man with subtotal gastrectomy for adenocarcinoma, whose postoperative course is complicated by a prolonged fever. Despite extensive diagnostics, the origin of the postoperative fever remains unexplained for 47 days, when the patient is transferred to the ICU because of lethargy, hemodynamic instability, lung edema and abdominal symptoms. The diagnosis of Addison crisis is established and under substitution with hydrocortisone all the symptoms rapidly resolve. Postoperative fever is relatively frequent and infectious causes account for about half of the cases only. An infectious origin has imperatively to be excluded when the fever arises later than 48 hrs after surgery. In case of prolonged fever we suggest to extend the differential diagnosis to other than infectious causes by means of special lists (e.g fever of unknown origin).
