PurposePatient safety indicators (PSIs) were developed as a tool for hospitals to identify potentially preventable complications and improve patient safety performance. The study aimed at measuring the incidence of the Agency for Healthcare Research and Quality (AHRQ) PSI03 (pressure ulcer [PU] rate) and to identify the association between PSI03 and clinical outcomes including death, readmission within 30 days and length of stay (LOS) at the cardiothoracic surgery hospital at Ain Shams University, Cairo, Egypt.Design/methodology/approachAn exploratory prospective cohort study was conducted to follow up patients, who fulfilled the inclusion criteria, from admission until one month after discharge at the cardiothoracic surgery hospital. Data were collected through basic information and follow-up sheets. The total number of included participants in the study was 330.FindingsPSI03 incidence rate was 67.7 per 1,000 discharges. Patients aged 60 years and above had the highest risk among all age groups. In patients who developed PSI03, the risk ratio (RR) of death was 8.8 [95% CI (3.79–20.24)], RR of staying more than 30 days at the hospital was 1.5 [95% CI (1.249–1.872)] and of readmission within 30 days in patients who developed PSI03 was 1.5 [95% CI (0.38–6.15)]. In the study’s hospital, the patients who developed PSI03 were at higher risk of death and stayed longer at the hospital than patients without PSI03. This study demonstrated a clear association between PSI03 and patient outcomes such as LOS and mortality. Early detection, prevention and proper management of PSI03 are recommended to decrease unfavorable clinical outcomes.Originality/valueThe importance of PSIs lies in the fact that they facilitate the recognition of the adverse events and complications which occurred during hospitalization and give the hospitals a chance to improve the possible clinical outcomes. Therefore, the current study aimed at measuring the association between AHRQ PSI03 ( PU rate) and the clinical outcomes including death, readmission within 30 days and the LOS at the cardiothoracic surgery hospital at Ain Shams University. This study will provide the hospital management with baseline data for this type of adverse event and guide them to develop a system for identifying the high-risk group of patients and to upgrade relevant hospital policies and guidelines that lead to improved patient outcomes.
Background: Tetralogy of Fallot is the most common cyanotic congenital heart defect. Borderline pulmonary anatomy has been associated with a higher risk of mortality and morbidity. Strategies to manage this condition—namely, single- or multistage repair—have long been debated. Objective: The overall outcomes of patients with tetralogy of Fallot with borderline pulmonary arteries (McGoon ratio 1.3 to 1.7) with regard to the need for a single-stage or multistage repair and the outcome of each surgical management were evaluated. Patients and methods: A retrospective, nonrandomized comparative study designed to evaluate patient outcomes comprised 60 patients with tetralogy of Fallot with borderline pulmonary arteries who underwent surgery at the Cardiothoracic Surgery Academy, Ain Shams University, Cairo, Egypt, between January 2016 and December 2017. After gaining approval from the affiliated ethical and research committee, and informed consent of the guardians, the patients were assigned into one of two groups. Shunt group included 30 patients managed surgically by a modified Blalock-Taussig (MBT) shunt as a part of a multistage repair, and repair group included 30 patients managed surgically by single-stage complete repair. The medical records of the patients were reviewed, and data relating to age, sex, weight, and preoperative oxygen saturation were collected. All patients underwent preoperative echocardiography and multislice computed tomography (CT) with angiography. The follow-up was performed by echocardiography at discharge and at one month and six months after surgery. Multislice CT with angiography was performed in patients who received a shunt once the echocardiography showed acceptable pulmonary arteries. Results: The patients’ age ranged from 5 to 50 months with a mean age of 18.63 ± 9.15 (19.84 ± 12.34 for the shunt group and 17.43 ± 8.54 for the repair group). The weight ranged from 5 kg to 18 kg with a mean of 9.6 ± 2.53 (8.82 ± 2.79 for the shunt group and 10.41 ± 2.63 for the repair group). The mean preoperative O2 saturation was 68.95% ± 7.8% for the shunt group and 87.93% ± 6.18% for the repair group. The median McGoon ratio was 1.4 for the shunt group and 1.6 for the repair group, the difference of which was highly significant (P < .0001). The mortality rate in our study was 10% (10% for the shunt group and 10% for the repair group). The morbidity incidence rate was 26.6% for the shunt and repair groups. The ICU stay ranged from 2 to 31 days, with a median of three days for the shunt group (mean 3.61 ± 1.91) and four days for the repair group (mean 6.07 ± 6.63 days). The calculated P value showed a significant difference between the two groups concerning ICU stay. The postoperative SO2 significantly increased to a mean of 85.58 ± 7.05 in the shunt group and 98.14 ± 3.36 in the repair group (P < .0001). Conclusion: There was no statistically significant difference between multistage repair and single-stage complete repair regarding morbidity and mortality. Regarding ICU stay, patients in the single-stage had a better outcome. A McGoon ratio of 1.5 can be used as a guideline in the decision-making process.
Background Large-volume therapeutic thoracocentesis may be associated with pulmonary congestion or a more serious complication; re-expansion pulmonary edema (RPE). We investigated whether monitoring pleural pressure with manometry during thoracocentesis would prevent these pulmonary symptoms/RPE and allow larger volume drainage. Methods We did a randomized controlled trial involving 110 patients with large malignant pleural effusions. Patients were randomly allocated to obtain thoracocentesis with or without pleural manometry. We measured the incidence of pulmonary congestion symptoms, total fluid aspirated, and pleural pressures in both groups. This trial is listed on ClinicalTrials.gov as NCT04420663. Results The mean amount of total thoracocentesis fluid withdrawn from the control group was 945.4±78.9 (mL) and 1690.9±681.0 (mL) from the intervention group (P<0.001). Clinical symptoms of pulmonary congestion appeared in (n=20) (36.3%) of patients in the intervention group while no symptoms appeared in controls (P<0.001). The difference between opening and closing pressures between the non-symptomatic cluster and the symptomatic cluster was (32.8±15.6 versus 42.2±13) respectively (P=0.02). Total fluid withdrawn from the non-symptomatic cluster was 1828.5±505 mL in comparison to 1,450±875 mL in the symptomatic cluster (P=0.04). Conclusion Pleural manometry can be used to increase the volume of fluid removed on each occasion in patients with malignant pleural effusion. In our study, pleural manometry was associated with a larger number of pulmonary congestion symptoms/RPE. We believe that manometry may be a useful tool to not exceed a 17 cm H 2 O gradient in pleural pressure which should be avoided to prevent pulmonary congestion symptoms or RPE. Pulmonary congestion symptoms/RPE are not related to the amount of volume withdrawn but to the gradient of pleural pressure drop. Our conclusion does support the adoption of pleural manometry whenever large-volume thoracocentesis is intended.
Background Patient-prosthesis mismatch after mitral valve replacement has an unfavorable postoperative hemodynamic outcome, which underlines the importance of identifying and preventing prosthesis- and patient-related risk factors. This study was conducted to determine the incidence and identify possible predictors of patient-prosthesis mismatch. Methods A prospective study was conducted on 715 patients with a mean age of 42 ± 11 years who underwent mechanical mitral valve replacement between 2013 and 2017. The effective orifice area of the prostheses was estimated by the continuity equation, and a mismatch was defined as an effective orifice area index ≤1.2 cm2·m−2. The mean clinical and echocardiographic follow-up was 26.74 ± 11.58 months. Multivariate regression analysis was performed to identify predictors of patient-prosthesis mismatch. Results Patient-prosthesis mismatch was detected in 382 (53.4%) patients. A small mechanical prosthesis (<27 mm) was inserted in 54.3%. Mortality during follow-up was 9% (65 patients). Patient-prosthesis mismatch was identified in patients with preoperative rheumatic mitral valve pathology, associated tricuspid regurgitation, higher New York Heart Association class, preoperative atrial fibrillation, mitral stenosis, and small preoperative left ventricular dimensions. Multivariate analysis identified mitral stenosis, preoperative atrial fibrillation, and small postoperative left ventricular end-diastolic dimension as risk factors for patient-prosthesis mismatch. Conclusion Patient-prosthesis mismatch is a common sequela after mechanical mitral valve replacement. Identification of predictors of patient-prosthesis mismatch can help so that a preoperative strategy can be implemented to avoid its occurrence.
Background Major adverse cardiovascular events (MACE) are useful endpoints to evaluate cardiovascular outcomes. The aim of this study was to report our results in concordance with the expected improvement of records after using the online Research Electronic Data Capture (RedCap) software. Methods: We included patients who benefited from first time elective isolated coronary bypass grafting (CABG) at Ain-Shams university main hospital, in the period between April 2014 and April 2016; providing a minimum 2 years follow-up . Incidences, risk factors and independent predictors for MACE were calculated including; mortality, the occurrence or re-hospitalization for: heart failure, recurrence of angina or myocardial infarction (MI), cerebrovascular stroke (CVS), need of coronary angiography (CA), repeat percutaneous intervention (PTCA) or CABG. Results: 607 cases met our inclusion criteria and 105 patients (18.7%) developed 184 MACE, including 45 hospital mortalities (7.4%), 13 late mortalities (2.1%) and 126 non-fatal events recorded in 47 patients (7.7%); a majority (40 patients; 6.6%) had suffered from at least 3 non-fatal events. Two-years follow-up was complete for the 562 hospital survivors with a total of 1113 patient-years. The annualized incidence rates of ICU admission, repeated angina or MI, need for CA, PTCA, or CABG, development of CVS, heart failure, and late mortality were: 3.6%, 2.8%, 1.8%, 0.5%, 0.09%, 0.35%, 2% and 1.2% per patient-year; respectively. Independent predictors of hospital mortality were: advanced age at surgery (OR 1.06: 1-1.12; P = 0.049), female sex (OR 3.4: 1.3-8.9; P = 0.01), prolonged durations of: cardiopulmonary bypass CPB (OR 1.02: 1.01- 1.04; P < 0.001), mechanical ventilation (OR 1.07: 1.04- 1.09; P < 0.001) positive inotropic support (OR 1.03: 1.02- 1.05; P < 0.001) and ICU stay (OR 1.09: 1.07- 1.11; P < 0.001). Independent predictors of overall MACE were advanced age at surgery (OR 1.04: 1.01-1.07; P = 0.011), prolonged durations of: aortic cross clamp (OR 1.09: 1.04-1.11; P = 0.003), CPB (OR 1.06: 1.04-1.08; P < 0.001) and mechanical ventilation (OR 1.02: 1.01-1.03; P < 0.001). Conclusion: Our results suggested that more care should be given to females, elderly and to shorten and improve the quality of our operative times. The repetition of non-fatal MACE could be modified by closer observation of the patient, once developing his first event.
Background:The lateral thoracotomy approach for mitral valve surgery was used extensively in the early history of open-heart surgery. Postoperative sternal wound complications are the major problem with sternotomy incision, other disadvantages of median sternotomy is the bad cosmetic appearance of the scar, which is more prone to keloid formation. Aim of the Work:To compare the procedure and early postoperative outcome of the standard sternotomy approach for mitral valve repair surgery versus the video assisted minimally invasive approach through right anterolateral minithoracotomy. Patients and Methods:This study is a randomized, controlled and prospective study. It was conducted on 66 patients suffering from MVD selected randomly (purposive non probability sample) to compare procedure and early outcome of traditional sternotomy versus video assisted minimal invasive technique. Patients were divided into two groups of 33 cases, Group "A" underwent mitral valve surgery through video assisted minimally invasive right anterolateral video-assisted minithoracotomy, while group 'B" underwent mitral valve repair surgery through a conventional median sternotomy from 2020 to August 2021.Results: There was no statistically significant difference as regards the age, sex, NYHA, preoperative echocardiographic findings. Regarding intraoperative comparison, there was highly statistically significant difference in the cross-clamp time, total bypass time and total operative time, this difference may be due to the new experiences in MIMVS. The length of the incision was highly significantly lesser in group "A" than in group "B", There was significant difference in the intensive care parameters. The mechanical ventilation time was shorter in group "A", the blood loss and the blood transfusion required was lesser in group "A". The ICU stay was shorter in group "A". There was significantly less postoperative pain in group (A) than in group (B). Total hospital stay was less in group (A) than in group (B). The complications of group "A" were less serious than those in group "B" but there was no statistical significance. MIMVS was more cost effective than sternotomy group. Conclusion:In patients with mitral valve disease, minimally invasive surgery may be an alternative to conventional mitral valve surgery. Right anterolateral minithoracotomy provides excellent exposure of the mitral valve and offers a better cosmetic lateral scare comparable short-term mortality. Comparable in-hospital morbidity (renal, pulmonary, cardiac complications, and readmissions), Reduced pain perception, transfusions, postoperative blood loss,
Background: Obesity has a great impact on overall mortality and morbidity in cardiac surgery. The magnitude of obesity is defined by means of body mass index (BMI). At this study we aim to correlate between grade of BMI and postoperative complications in patients undergoing coronary revascularization. Methods: A prospective observational study was conducted in Ain Shams University hospitals and the National Heart Institute of Egypt. 98 patients with multi-vessel CAD and candidate for CABG were included in the study and divided into two groups Group I: 53 patients with BMI over 30. Group II: 45 patients with a BMI under 30. The primary endpoint was wound infection and mediastinitis. Secondary endpoints included mortality, prolonged ICU and hospital stay, stroke, renal and hepatic impairment. Results: As regard primary ending point, eight patients of Group I had their wounds infected which is significantly higher than the other group (p-value 0.034). The total ward stay in days was significantly higher in Group I (p-value 0.027). Conclusion: BMI more than 30 is associated with increased rates of wound complications either superficial or deep wound infections. Robust measures should be taken to prevent such grave complications.
