Project description:BackgroundInterest in outpatient total hip arthroplasty (THA) and total knee arthroplasty (TKA) has increased recently as part of value-based care and early recovery protocols. Outpatient pathways require significant paradigm shifts, are not used widely, and are mostly implemented at outpatient surgery centers or orthopedic specialty hospitals. In this article, we report on the outcomes of implementation of an outpatient arthroplasty protocol at a tertiary care academic medical center.MethodsWe performed a retrospective review on a series of 105 consecutive patients who underwent THA or TKA following our newly implemented outpatient arthroplasty protocol. We compared these patients to a group of inpatient arthroplasty patients from the same time period.ResultsEighty-three of 105 (79%) patients were successfully discharged home on the day of surgery. Successful same-day discharge was predicted by early ambulation (P = .01), TKA over THA (P = .04), and shorter duration of surgery (P = .01). General anesthesia correlated with better early ambulation distances (P = .03) and a lower incidence of urinary retention (P = .049). The outpatient readmission and complication rates were 0.95% and 1.9%, respectively, whereas the matched inpatient rates were 3.7% and 2.9%, respectively.ConclusionsOutpatient THA and TKA in a well-selected patient is feasible in an academic multidisciplinary tertiary care hospital, with complication rates approximating inpatient surgery. The findings reported here can be used to further optimize outpatient arthroplasty protocols.

Project description:Real world effectiveness, toxicity and costs analyses from chimeric antigen receptor (CAR)-T cell therapy are of utmost relevance to determine whether and how to offer patients highly personalized immunotherapy. In this study, we aimed at describing CAR T-cells effectiveness, safety and costs in a Portuguese Comprehensive Cancer Center. We performed a retrospective descriptive study of adult patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL), primary mediastinal B-cell lymphoma and transformed follicular lymphoma referred to CAR T-cell therapy, between May 2019 and February 2021. Rates of treatment response, toxicity and survival (Kaplan-Meier method) were analyzed by intention-to-treat. Direct medical costs stratified by inpatient-care, outpatient-care, and diagnostic-therapeutic procedures (DTP) were derived based on resources used and their respective unit costs. In twenty patients (median age 49.5y; 55%male; 70%DLBCL; 50% with primary refractory disease), best overall and complete response rates were 65.0% and 45.0%, respectively. Median overall (OS) and progression-free survivals were 9.2 and 7.3 months; 12-month OS rate was 42.6% (95%CI:23.2-78.3). Grade≥3 cytokine release syndrome and neurotoxicity occurred in 5.6% and 11.1% of patients, respectively. CAR T-cell therapy expenditure, including adverse events costs, was 7 176 196€, or 286 238€ when excluding drug cost. Median cost for treated patient was 355 165€ with CAR T-cell drug cost accounting for 97.0% of the overall expense. Excluding CAR T-cell acquisition cost, inpatient-care and DTP accounted for 57% and 38% of total cost/patient, respectively. Our findings highlight the heavy economic burden of CAR T-cell therapy driven by drug acquisition costs.

Project description:IntroductionWhipple procedure is one of the major surgeries performed in tertiary care centers. Once considered a high mortality procedure is now being practicing with mortality declining to less than 5%. This study describes our five-year experience of the Whipple procedure in terms of preoperative, operative, and postoperative parameters of patients undergoing surgery in a local tertiary care setting.Material and methodsThis was a non-randomized interventional study that was conducted at the Surgical Department of Services Hospital Lahore from January 2014 to December 2018. A total of 57 Whipple procedures were performed during this period. Demographic data, presenting symptoms, physical signs, past medical history, preoperative stenting details, intra-operative duration of surgery, postoperative course and complications, pathology, and causes of postoperative death were collected on a pre-designed questionnaire. Data were entered and analyzed by using SPSS 22 (IBM Corp., Armonk, USA).ResultsOut of 57 patients, 19 were females and 38 were males. The mean age of patients was 53±05 years. The most common presenting symptom was jaundice 39 (68.4%), followed by abdominal pain 32 (56.1%). The mean size of the tumor on CT-scan was 2.8±1.4 cm, the mean operation time was 315±38.3 min, mean blood loss during surgery was 500±130 ml, and mean hospital stay was 10±6 days. The major postoperative complication was the pancreatic fistula (12%). Twenty-one out of 39 patients presented with jaundice had undergone preoperative biliary stenting by endoscopic retrograde biliary stenting. The most common histological diagnosis was adenocarcinoma of pancreas 19 (33.3%). Out of 57 patients, nine (15.8%) patients expired in the first 30 days and the most frequent cause of mortality was septic shock.ConclusionIn this study, the most common presentation of patients undergoing Whipple procedure was obstructive jaundice, the most frequent operative complication was pancreatic fistula, and the most prevalent histopathology was carcinoma of the pancreas. Perioperative parameters such as mean operative time, mean blood loss during surgery, and mean length of hospital stay were comparable with other studies. However, mortality in this study was slightly higher. It can be concluded that with meticulous surgical technique, securing hemostasis strictly and standard critical care postoperatively can decrease morbidity and mortality after the Whipple procedure.

Project description:Chimeric antigen receptors (CAR) are genetically engineered receptors that can recognise specific antigens and subsequently activate downstream signalling. Human T cells engineered to express a CAR, also known as CAR-T cells, can target a specific tumour antigen on the cell surface to mediate a cytotoxic response against the tumour. CAR-T cell therapy has achieved remarkable success in treating hematologic malignancies, but not in solid tumours. Currently, extensive research is being carried out to make CAR-T cells a therapy for solid tumours. To date, most of the research interest in the field has focused on cytotoxic T lymphocytes as the carrier of CAR products. However, in addition to T cells, the CAR design can be introduced in other immune cells, such as natural killer (NK)/NKT cells, γδ T cells, mucosal-associated invariant T (MAIT) cells, dendritic cells (DC), macrophages, regulatory T cells (Treg), B cells, etc. Some of the CAR-engineered immune cells, such as CAR- γδ T and CAR-NK/NK-T cells, are directly involved in the anti-tumour response, demonstrated in preclinical studies and/or clinical trials. CAR-Tregs showed promising therapeutic potential in treating autoimmune diseases. In particular, B cells engineered with chimeric receptors can be used as a platform for long-term delivery of therapeutic proteins, such as recombinant antibodies or protein replacement, in an antigen-specific manner. CAR technology is one of the most powerful engineering platforms in immunotherapy, especially for the treatment of cancers. In this review, we will discuss the recent application of the CAR design in non-CAR-T cells and future opportunities in immunotherapy.

Project description:ObjectiveThe COVID-19 pandemic has forced healthcare providers worldwide to bring in changes in the way cancer patients are cared for. Many cancer departments globally have brought in changes to their daily practice. This article is about our experience of evolving "COVID 19 PROTOCOL" devised in our department and taking a shape to suit a health care system with limited budget.Materials and methodsAll the patient census & details of department of surgical oncology, Royapettah cancer hospital, from month of March 2020 to July 2020, who were subjected to COVID protocol were compared to patient census of similar duration in immediate past five months of October 2019 to February 2020. The data from out-patient department, ward in-patient census and healthcare personnel data was analyzed.ResultsThere was a drop to 63.5% in OP census and 61.6% in IP census. There was a drop to 64.5% in number of major cases operated during initial phases of COVID pandemic. Health care workers were also infected with the COVID but cross infectivity can be checked if proper steps to adhere to an institutional protocol based on general measures of cleanliness are taken.ConclusionAdherence to an institutional protocol based on compliance to general measures of masking, hand washing and social distancing plays a major role in minimizing disease spread. The Royapettah COVID protocol, though in process of evolution, can be recommended for any health care center with limited resources.

Project description:BackgroundThe value of early integration of palliative care has been demonstrated increasingly for the past years in both oncological and nononcological diseases. Outpatient palliative care services might represent a feasible approach to implement supportive care in early disease. In this study, we aimed at evaluating which patients use and benefit from outpatient palliative care services, which symptoms are addressed most, and which support services are installed in this early phase of disease.MethodsWe retrospectively analyzed the entire patient collective of a recently developed palliative care outpatient clinic within the leading university hospital in Switzerland for a period of five years. Sociodemographics, symptoms, and information on disease as well as patient-reported outcomes were retrieved from the electronic patient files. Demographic and clinical data were analyzed by descriptive statistics between groups and survival was analyzed by means of Kaplan-Meier estimates and log-rank test.ResultsWe report on 642 consultations of 363 patients between 2016 and 2020. Patients had a mean of 1.8 visits (range 1-10), with n = 340 patients (93.7%) of patients suffering from an oncological disease. Overall symptom load was high, with n = 401 (73.7%) of patient-reported outcomes reporting two or more symptoms. Distress levels of 5 or higher were reported in n = 78 (30.4%) of available patient-reported outcomes. Independent of the origin of primary disease and the length of the disease trajectory, patients were referred to the palliative care service in median only four months before death.ConclusionWe identify high symptom load and distress in the outpatient palliative patient population. Patients benefitted from supportive medication, improvement of ambulatory support systems and advance care planning, and more than one-third of patients remained in follow-up, indicating a good acceptance of the service. Overcoming the overall late referral could, however, further increase the quality of life at earlier stages of disease.

Project description:BackgroundTransvenous Lead Extraction (TLE) is a standard treatment for some late Cardiac Implantable Electronics Device (CIED) complications. The outcome of transvenous lead extraction procedure in Thailand is not robust.MethodsA Single-center retrospective cohort of TLE procedures performed at Ramathibodi hospital between January 2008 and December 2020 was studied.ResultsThere were 157 leads from 105 patients who underwent lead removal procedure during the specified period. Data analysis was performed from 79 TLE patients due to incomplete data and lead explant procedure of the excluded subjects. Mean patients' age was 57.7 ± 18.7 years, with 70.9% male. There were 82 pacemaker leads, 35 ICD leads, and 5 CS leads (mean number of leads were 1.54 ± 0.66 per patient), with mean implanted duration of 87.8 ± 68.2 months. Main indication for TLE was infection-related, which accounted for 67.1% of the cases. Overall clinical success rate was 97.5%. Mean operative time was 163.8 ± 69.5 min. Major complications occurred in 4 patients (5.1%) with one in-hospital mortality from severe sepsis.ConclusionTLE using laser sheath and rotating mechanical sheath for transvenous lead extraction is effective and safe, even outside high-volume center.

Project description:ICU is a multifaceted organization where multiple teams care for critically ill patients. In the current era, collaboration between teams and efficient workflows form the backbone of value-based care. Geographical cohorting is a widespread model for hospitalist rounding, but its role in ICUs is unclear. This study evaluates the outcomes of geographical cohorting in a large ICU of an Academic Health Center.DesignThis is a retrospective analysis of quality metrics collected 12 months pre- and post-implementation of geographical cohorting.SettingA total of 130 bedded ICU at tertiary academic health center in Midwest.PatientsAll patients admitted to the ICU.InterventionsOur institution piloted the geographical cohorting model for critical care physician rounding on September 1, 2018.MeasurementsThe quality metrics were categorized as ICU harm events and ICU hospital metrics. Team of critical care providers were surveyed 12 months after implementation.Main resultsThe critical care utilization in the pre- and post-implementation numbers were similar for patient days (pre = 34,839, post = 35,155), central-line days (pre = 17,648, post = 19,224), and Foley catheter days (pre = 18,292, post = 17,364). The ICU length of stay was similar (4.9 d) in both pre- and post-intervention periods. Significant reduction in the incidence of Clostridium difficile infection (relative risk, -0.50; 95% CI, 0.25-0.96; p = 0.039), hospital-acquired pressure injury (relative risk, -0.60; 95% CI, 0.39-0.92; p = 0.020), central line-associated bloodstream infection incidence (relative risk, -0.19; 95% CI, 0.05-0.52; p = 0.008), and catheter-associated urinary tract infection (relative risk, -0.52; 95% CI, 0.29-0.93; p = 0.027). Healthcare providers perceived optimal utilization of their time, reduced interruptions, and improved coordination of care with geographical rounding.ConclusionsGeographical cohorting improves coordination of care, physician workflow, and critical care quality metrics in very large ICUs.
