RESUMO

BACKGROUND: Rural Australians typically encounter disparities in healthcare access leading to adverse health outcomes, delayed diagnosis and reduced quality of life (QoL) parameters. These disparities may be exacerbated in advanced malignancies, where treatment is only available at highly specialised centres with appropriate multidisciplinary expertise. Thus, this study aims to determine the association between patient residence on oncological, surgical and QoL outcomes following cytoreductive surgery (CRS) and hyperthermic intra-peritoneal chemotherapy (HIPEC). METHODS: A retrospective analysis was conducted on consecutive patients undergoing CRS and HIPEC at Royal Prince Alfred Hospital from January 2017 to March 2022. On the basis of their postcode of residence, patients were stratified into metropolitan and regional groups. Data encompassing demographics, oncological, surgical and QoL outcomes were compared. Statistical analysis included chi-square test, t-tests and Kaplan-Meier survival curves. RESULTS: Among the 317 patients, 228 (72%) were categorised as metropolitan and 89 (28%) as regional. Metropolitan patients presented higher rates of recurrence (61.8% versus 40.0%, p = 0.014) and shorter overall mean survival [3.8 years (95% CI: 3.44-4.09) versus 4.2 years (95% CI: 3.76-4.63), p = 0.019] compared with regional patients. No other statistically significant differences were observed in oncological, surgical and QoL outcomes. CONCLUSIONS: Most oncological, surgical and QoL parameters did not differ by geographical location of patients undergoing CRS and HIPEC for peritoneal malignancies at a high-volume quaternary referral centre. Observed differences in recurrence and survival may be attributed to the selective nature of surgical referrals and variable follow-up patterns. Future research should focus on characterising referral pathways and its influence on post-operative outcomes.

RESUMO

This study aims to compare surgical outcomes and in-hospital cost between robotic-assisted surgery (RAS), laparoscopic and open approaches for benign gynaecology, colorectal and urological patients and to explore the association between cost and surgical complexity. This retrospective cohort study included consecutive patients undergoing RAS, laparoscopic or open surgery for benign gynaecology, colorectal or urological conditions between July 2018 and June 2021 at a major public hospital in Sydney. Patients' characteristics, surgical outcomes and in-hospital cost variables were extracted from the hospital medical records using routinely collected diagnosis-related groups (DRG) codes. Comparison of the outcomes within each surgical discipline and according to surgical complexity were performed using non-parametric statistics. Of the 1,271 patients included, 756 underwent benign gynaecology (54 robotic, 652 laparoscopic, 50 open), 233 colorectal (49 robotic, 123 laparoscopic, 61 open) and 282 urological surgeries (184 robotic, 12 laparoscopic, 86 open). Patients undergoing minimally invasive surgery (robotic or laparoscopic) presented with a significantly shorter length of hospital stay when compared to open surgical approach (P < 0.001). Rates of postoperative morbidity were significantly lower in robotic colorectal and urological procedures when compared to laparoscopic and open approaches. The total in-hospital cost of robotic benign gynaecology, colorectal and urological surgeries were significantly higher than other surgical approaches, independent of the surgical complexity. RAS resulted in better surgical outcomes, especially when compared to open surgery in patients presenting with benign gynaecology, colorectal and urological diseases. However, the total cost of RAS was higher than laparoscopic and open surgical approaches.

RESUMO

INTRODUCTION: National and international clinical practice guidelines have stratified the value of osteoarthritis (OA) interventions. Interventions with strong evidence supporting effectiveness and benefit are 'high value care'. Appointment attendance, audits and practitioner surveys are widely used to determine frequency of recommendations and adherence to high value care. Greater patient reported data is needed in this evidence base. OBJECTIVE: To describe the frequency of high and low value care being recommended and undertaken by individuals awaiting OA-related lower limb arthroplasty. To examine sociodemographic or disease-related variables associated with being recommended different levels of care. METHODS: A cross-sectional survey of 339 individuals was conducted in metropolitan and regional hospitals and surgeon consultation rooms across New South Wales (NSW), Australia. Individuals attending pre-arthroplasty clinics/appointments for primary arthroplasty of the hip and/or knee were invited to participate. Respondents were asked what intervention(s) they were recommended by healthcare practitioners, or other sources of information, and what they had undertaken within two years prior to hip or knee arthroplasty. Interventions were classified as core, recommended, and low value care aligned with the Osteoarthritis Research Society International (OARSI) guidelines. We considered core and recommended interventions high value. The proportion of recommended and undertaken interventions were calculated. We used backwards stepwise multivariate multinomial regression to address aim three. RESULTS: Simple analgesics were most frequently recommended (68% [95% CI 62.9 to 73.1]). 24.8% [20.2 to 29.7] of respondents were recommended high value care only. 75.2% [70.2 to 79.7] of respondents were recommended at least one low value intervention. More than 75% of recommended interventions were undertaken. Respondents awaiting hip arthroplasty, living outside a major city and without private health insurance had greater odds of recommended rather than core interventions being advised. CONCLUSION: While high value interventions are being recommended to individuals living with OA, in most cases they are combined with recommendations for low value care. This is concerning given the high rates of uptake for recommended interventions. Based on patient reported data, disease-related and sociodemographic variables influence the level of care recommended.

RESUMO

AIMS: Contemporary cardiac intensive care unit (CICU) outcomes remain highly heterogeneous. As such, a risk-stratification tool using readily available lab data at time of CICU admission may help inform clinical decision-making. METHODS AND RESULTS: The primary derivation cohort included 4352 consecutive CICU admissions across 25 tertiary care CICUs included in the Critical Care Cardiology Trials Network (CCCTN) Registry. Candidate lab indicators were assessed using multivariable logistic regression. An integer risk score incorporating the top independent lab indicators associated with in-hospital mortality was developed. External validation was performed in a separate CICU cohort of 9716 patients from the Mayo Clinic (Rochester, MN, USA). On multivariable analysis, lower pH [odds ratio (OR) 1.96, 95% confidence interval (CI) 1.72-2.24], higher lactate (OR 1.40, 95% CI 1.22-1.62), lower estimated glomerular filtration rate (OR 1.26, 95% CI 1.10-1.45), and lower platelets (OR 1.18, 95% CI 1.05-1.32) were the top four independent lab indicators associated with higher in-hospital mortality. Incorporated into the CCCTN Lab-Based Risk Score, these four lab indicators identified a 20-fold gradient in mortality risk with very good discrimination (C-index 0.82, 95% CI 0.80-0.84) in the derivation cohort. Validation of the risk score in a separate cohort of 3888 patients from the Registry demonstrated good performance (C-index of 0.82; 95% CI 0.80-0.84). Performance remained consistent in the external validation cohort (C-index 0.79, 95% CI 0.77-0.80). Calibration was very good in both validation cohorts (r = 0.99). CONCLUSION: A simple integer risk score utilizing readily available lab indicators at time of CICU admission may accurately stratify in-hospital mortality risk.

RESUMO

Structural color─optical response due to light diffraction or scattering from submicrometer-scale structures─is a promising means for sustainable coloration. To expand the functionality of structural color, we introduce discoidal shape anisotropy into colloidal particles and characterize how structural color reflection can be engineered. Uniaxial compression of spheres is used to prepare discoids with varying shape anisotropy and particle size. Discoids are assembled into thin films by evaporation. We find that structural color of assembled films displays components due to diffuse backscattering and multilayer reflection. As discoids become more anisotropic, the assembled structure is more disordered. The multilayer reflection is suppressed─peak height becomes smaller and peak width broader; thus, the color is predominantly from diffuse backscattering. Finally, the discoid structural color can be tuned by varying particle size and has low dependence on viewing angle. We corroborate our results by comparing experimental microstructures and measured reflection spectra with Monte Carlo simulations and calculated spectra by finite-difference time-domain simulation. Our findings demonstrate that the two tunable geometries of discoids─size and aspect ratio─generate different effects on spectral response and therefore can function as independent design parameters that expand possibilities for producing noniridescent structural color.

RESUMO

BACKGROUND: Laparoscopic-assisted surgery for rectal cancer is widely used, however the healthcare costs are thought to be higher than for open resection. This secondary endpoint analysis of a randomized controlled trial aimed to evaluate total healthcare costs of laparoscopic-assisted surgery compared with open resection for rectal cancer over a 12-month period. METHODS: Patients in the Australasian Laparoscopic Cancer of the Rectum Trial (ALaCaRT) were included in a prospective costing analysis. All healthcare use for the index surgery and hospital admission, readmissions, and follow-up care over 12 months were included. Unit costs were valued in Australian dollars (AUD$) using scheduled Medicare fees and hospital cost weights. The primary outcome was mean per patient cost. Non-parametric bootstrapping with 10,000 replications was undertaken for robustness checks. RESULTS: Data from 468 patients indicated that the laparoscopic-assisted surgical procedure incurred a mean cost of AUD$4542 (standard deviation [SD] AUD$1050)-AUD$521 higher than the open procedure mean cost of AUD$4021 (SD AUD$804) due to longer operative time and involvement of more costly equipment (95% confidence interval [CI] AUD$354-AUD$692). At 12 months, the average cost for the laparoscopic-assisted and open groups was AUD$43,288 (SD AUD$40,883) and AUD$45,384 (SD AUD$38,659), respectively, due to the shorter subsequent hospital stays. No overall significant cost difference between groups was found (95% CI -AUD$9358 to AUD$5003). One-way sensitivity analyses confirmed the robustness of the results. CONCLUSION: While initially higher, the costs of laparoscopic-assisted surgery for rectal cancer were similar to open resection at 12 months. Clinicians may choose a surgical approach based on clinical need. TRIAL REGISTRATION: The Australasian Gastro-Intestinal Trials Group (AGITG) was the legal sponsor and trial coordination was performed by the NHMRC Clinical Trials Centre. The trial was registered with the Australian and New Zealand Clinical Trial Registry (ACTRN12609000663257).

RESUMO

Regional soft tissue mechanical strain offers crucial insights into tissue's mechanical function and vital indicators for different related disorders. Tagging magnetic resonance imaging (tMRI) has been the standard method for assessing the mechanical characteristics of organs such as the heart, the liver, and the brain. However, constructing accurate artifact-free pixelwise strain maps at the native resolution of the tagged images has for decades been a challenging unsolved task. In this work, we developed an end-to-end deep-learning framework for pixel-to-pixel mapping of the two-dimensional Eulerian principal strains [Formula: see text] and [Formula: see text] directly from 1-1 spatial modulation of magnetization (SPAMM) tMRI at native image resolution using convolutional neural network (CNN). Four different deep learning conditional generative adversarial network (cGAN) approaches were examined. Validations were performed using Monte Carlo computational model simulations, and in-vivo datasets, and compared to the harmonic phase (HARP) method, a conventional and validated method for tMRI analysis, with six different filter settings. Principal strain maps of Monte Carlo tMRI simulations with various anatomical, functional, and imaging parameters demonstrate artifact-free solid agreements with the corresponding ground-truth maps. Correlations with the ground-truth strain maps were R = 0.90 and 0.92 for the best-proposed cGAN approach compared to R = 0.12 and 0.73 for the best HARP method for [Formula: see text] and [Formula: see text], respectively. The proposed cGAN approach's error was substantially lower than the error in the best HARP method at all strain ranges. In-vivo results are presented for both healthy subjects and patients with cardiac conditions (Pulmonary Hypertension). Strain maps, obtained directly from their corresponding tagged MR images, depict for the first time anatomical, functional, and temporal details at pixelwise native high resolution with unprecedented clarity. This work demonstrates the feasibility of using the deep learning cGAN for direct myocardial and liver Eulerian strain mapping from tMRI at native image resolution with minimal artifacts.

RESUMO

BACKGROUND: A barrier to the uptake of robotic-assisted surgery (RAS) continues to be the perceived high costs. A lack of detailed costing information has made it difficult for public hospitals in particular to determine whether use of the technology is justified. This study aims to provide a detailed description of the patient episode costs and the contribution of RAS specific costs for multiple specialties in the public sector. METHODS: A retrospective descriptive costing review of all RAS cases undertaken at a large public tertiary referral hospital in Sydney, Australia from August 2016 to December 2018 was completed. This included RAS cases within benign gynaecology, cardiothoracic, colorectal and urology, with the total costs described utilizing various inpatient costing data, and RAS specific implementation, maintenance and consumable costs. RESULTS: Of 211 RAS patients, substantial variation was found between specialties with the overall median cost per patient being $19,269 (Interquartile range (IQR): $15,445 to $32,199). The RAS specific costs were $8828 (46%) made up of fixed costs including $4691 (24%) implementation and $2290 (12%) maintenance, both of which are volume dependent; and $1848 (10%) RAS consumable costs. This was in the context of 37% robotic theatre utilisation. CONCLUSIONS: There is considerable variation across surgical specialties for the cost of RAS. It is important to highlight the different cost components and drivers associated with a RAS program including its dependence on volume and how it fits within funding systems in the public sector.

RESUMO

BACKGROUND: Cost-effective cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for treatment of patients with peritoneal malignancy remains an ongoing financial challenge for healthcare systems, hospitals and patients. This study aims to describe the detailed in-hospital costs of CRS and HIPEC compared with an Australian Activity Based Funding (ABF) system, and to evaluate how the learning curve, disease entities and surgical outcomes influence in-hospital costs. METHODS: A retrospective descriptive costing review of all CRS and HIPEC cases undertaken at a large public tertiary referral hospital in Sydney, Australia from April 2017 to June 2019. In-hospital cost variables included staff, critical care, diagnosis, operating theatre, and other costs. Univariate and multivariate analyses were conducted to investigate the differences between actual cost and the provision of funding, and potential factors associated with these costs. RESULTS: Of the 118 CRS and HIPEC procedures included in the analyses, the median total cost was AU$130,804 (IQR: 105,744 to 153,972). Provision of funding via the ABF system was approximately one-third of the total CRS and HIPEC costs (p < 0.001). Surgical staff proficiency seems to reduce the total CRS and HIPEC costs. Surgical time, length of intensive care unit and hospital stay are the main predictors of total CRS and HIPEC costs. CONCLUSION: Delivery of CRS and HIPEC is expensive with high variability. A standard ABF system grossly underestimates the specific CRS and HIPEC funding required with supplementation essential to sustaining this complex highly specialised service.

RESUMO

The COVID-19 pandemic has presented a major unanticipated stress on the workforce, organizational structure, systems of care, and critical resource supplies. To ensure provider safety, to maximize efficiency, and to optimize patient outcomes, health systems need to be agile. Critical care cardiologists may be uniquely positioned to treat the numerous respiratory and cardiovascular complications of the SARS-CoV-2 and support clinicians without critical care training who may be suddenly asked to care for critically ill patients. This review draws upon the experiences of colleagues from heavily impacted regions of the United States and Europe, as well as lessons learned from military mass casualty medicine. This review offers pragmatic suggestions on how to implement scalable models for critical care delivery, cultivate educational tools for team training, and embrace technologies (e.g., telemedicine) to enable effective collaboration despite social distancing imperatives.

RESUMO

BACKGROUND: Pelvic exenterations are extensive surgical procedures for locally advanced or recurrent malignancies of the pelvis. However, this is often at the cost of significant morbidity due to perioperative pain, which has been poorly studied. OBJECTIVE: This study aims to review perioperative pain management in patients undergoing pelvic exenteration. DESIGN: This is a retrospective review of patients undergoing pelvic exenteration between January 2013 and December 2014. Data were gathered from medical records and a prospectively maintained database. SETTING: This study was conducted at a single quaternary referral center for pelvic exenteration. PATIENTS: Consecutive patients underwent pelvic exenteration at a single center. INTERVENTIONS: Pelvic exenteration was performed in consecutive patients. MAIN OUTCOMES MEASURES: Primary outcomes were the prevalence of preoperative pain, preoperative opiate use (type, dosage), and postoperative pain (verbal numerical rating scale). Secondary outcomes included the number of pain consultations and correlations between preoperative opiate use, length of stay, and extent of resection (en bloc sacrectomy and nerve excision). RESULTS: Ninety-nine patients underwent pelvic exenteration. Sixty-one patients (61.6%) underwent major nerve resection and/or sacrectomy. Thirty patients (30%) required opiates preoperatively, with a mean daily morphine equivalent of 72.9 mg (SD 65.0 mg). Patients on preoperative opiates were more likely to have worse pain postoperatively and to require higher opiate doses and more pain consultations (9.3 vs 4.8; p < 0.001). Major nerve excision and sacrectomy were not associated with worse postoperative pain. By discharge, 60% still required opiate analgesia. LIMITATIONS: Retrospective study design, the subjective nature of pain assessment because of a lack of valid methods to objectively quantify pain, and the lack of long-term follow-up were limitations of this study. CONCLUSIONS: Perioperative pain is a significant issue among patients undergoing pelvic exenteration. One in three patients require high-dose opiates preoperatively that is associated with worse pain outcomes. Potential areas to improve pain outcomes in these complex patients could include increased use of regional anesthesia, antineuropathic agents, and opiate-sparing techniques.

RESUMO

The male factor contributes approximately 50% to infertility-related cases in couples with an estimated 12%-35% of these cases attributable to male genital tract infections. Depending on the nature of the infection, testicular sperm production, sperm transport, and sperm function can be compromised. Yet, infections are potentially treatable causes of infertility. Male genital tract infections are increasingly difficult to detect. Moreover, they often remain asymptomatic ("silent") with the result that they are then passed on to the relevant sexual partner leading to fertilization and pregnancy failure as well as illness of the offspring. With the worldwide increasing problem of antibiotic resistance of pathogens, proper diagnosis and therapy of the patient is important. This testing, however, should include not only aerobic microbes but also anaerobic as these can be found in almost all ejaculates with about 71% being potentially pathogenic. Therefore, in cases of any indication of a male genital tract infection, a semen culture should be carried out, particularly in patients with questionable semen quality. Globally, an estimate of 340 million new infections with sexually transmitted pathogens is recorded annually. Among these, the most prevalent pathogens including Chlamydia trachomatis, Ureaplasma urealyticum, Neisseria gonorrhoeae, and Mycoplasma hominis. Escherichia coli are considered the most common nonsexually transmitted urogenital tract microbes. These pathogens cause epididymitis, epididymo-orchitis, or prostatitis and contribute to increased seminal leukocyte concentrations.

RESUMO

Practicing orthopaedic surgeons must assess the effects of the learning curve on patient safety and surgical outcomes if a new implant, technique, or approach is being considered; however, it remains unclear how learning curves reported in the literature should be interpreted and to what extent their results can be generalized. Learning curve reports from other surgical specialties and from orthopaedic surgery can be analyzed to identify the strengths and weaknesses of learning curve reporting. Single-surgeon series and registry data can be analyzed to understand learning challenges and to develop a personalized learning plan. Learning curve reports from single-surgeon series have several limitations that result from the limited dataset reported and inconsistencies in the way data are reported. Conversely, learning curve reports from registry data are likely to have greater generalizability, but are largely beneficial retrospectively, after data from a sufficient number of surgeons are assessed. There is a pressing need for surgeons to develop improved and consistent standards for learning curve reporting. Although registry data may provide better prospective measures in the future, the implementation of such registries faces several challenges. Despite substantial limitations, single-surgeon series remain the most effective way for practicing surgeons to assess their learning challenge and develop an appropriate learning plan.

RESUMO

PURPOSE: The aim of this systematic review and meta-analysis was to compare the role of FDG-positron emission tomography (PET) or PET/computed tomography (CT) with conventional imaging in the detection of primary and nodal disease in anal cancer, and to assess the impact of PET or PET/CT on the management of anal cancer. METHODS: A systematic review of the literature was performed. Eligible studies included those comparing PET or PET/CT with conventional imaging in the staging of histologically confirmed anal squamous cell carcinoma (SCC), or studies that performed PET or PET/CT imaging to assess response following treatment. RESULTS: Twelve studies met the inclusion criteria. For the detection of primary disease, CT and PET had a sensitivity of 60 % (95 % confidence interval [CI] 45.5-75.2) and 99 % (95 % CI 96-100), respectively. Compared with conventional imaging, PET upstaged 15 % (95 % CI 10-21) and downstaged 15 % (95 % CI 10-20) of nodal disease. This led to a change in nodal staging in 28 % of patients (95 % CI 18-38). When only studies performing contemporary PET/CT were considered, the rate of nodal upstaging was 21 % (95 % CI 13-30) and the TNM stage was altered in 41 % of patients. Following chemoradiotherapy, 78 % (95 % CI 65-88) of patients had a complete response on PET. CONCLUSION: Compared with conventional imaging, PET or PET/CT alters the nodal status in a sufficient number of cases to justify its routine use in the staging of patients with anal SCC.

RESUMO

PURPOSE: To investigate the effectiveness of a centralized, nurse-delivered telephone-based service to improve care coordination and patient-reported outcomes after surgery for colorectal cancer. PATIENTS AND METHODS: Patients with a newly diagnosed colorectal cancer were randomly assigned to the CONNECT intervention or usual care. Intervention-group patients received standardized calls from the centrally based nurse 3 and 10 days and 1, 3, and 6 months after discharge from hospital. Unmet supportive care needs, experience of care coordination, unplanned readmissions, emergency department presentations, distress, and quality of life (QOL) were assessed by questionnaire at 1, 3, and 6 months. RESULTS: Of 775 patients treated at 23 public and private hospitals in Australia, 387 were randomly assigned to the intervention group and 369 to the control group. There were no significant differences between groups in unmet supportive care needs, but these were consistently low in both groups at both follow-up time points. There were no differences between the groups in emergency department presentations (10.8% v 13.8%; P = .2) or unplanned hospital readmissions (8.6% v 10.5%; P = .4) at 1 month. By 6 months, 25.6% of intervention-group patients had reported an unplanned readmission compared with 27.9% of controls (P = .5). There were no significant differences in experience of care coordination, distress, or QOL between groups at any follow-up time point. CONCLUSION: This trial failed to demonstrate substantial benefit of a centralized system to provide standardized, telephone follow-up for postoperative patients with colorectal cancer. Future interventions could investigate a more tailored approach.

RESUMO

Need is a pivotal concept within health systems internationally given its driving force in health care policy, development, and delivery at population and individual levels. Needs assessments are critical activities undertaken to ensure that health services continue to be needed and to identify new target populations that demonstrate unmet need. The concept of need is underpinned by varied theoretical definitions originating from various disciplines. However, when needs are assessed, or health interventions developed based on need, little, if any, detail of the theoretical or conceptual basis of what is being measured is ever articulated. This is potentially problematic and may lead to measurement being invalid and planned health services being ineffective in meeting needs. Seldom are theoretical definitions of need ever compared and contrasted. This critical review is intended to fill this gap in the literature. Interpretations of the concept of need drawing from areas such as psychology, social policy, and health are introduced. The concept and relevance of unmet need for health services are discussed. It is intended that these definitions can be used to operationalize the term "need" in practice, theoretically drive needs assessment, and help guide health care decisions that are based upon need.

RESUMO

OBJECTIVES: Telephone-based supportive care presents a potentially highly accessible means of addressing unmet supportive care needs for people with cancer. Identification of behaviours that facilitate communication is essential for development of training for telephone-based supportive care. The aim of this study was to describe communication behaviours within supportive care telephone calls in two contexts (1) a telephone outreach intervention and (2) cancer helpline calls, to identify potential areas for further training. METHODS: 50 recorded calls were analysed using two standardised coding systems: the RIAS and Verona-CoDES-C. RESULTS: Mean call length was 21 min (304 utterances) for nurse-outreach calls and 23 min (355 utterances) for helpline calls. Closed questioning, verbal attentiveness and giving information/counselling were the most common communication behaviours identified. Emotional cues were most commonly responded to through non-explicit back-channelling, exploration of content or provision of reassurance or advice. CONCLUSIONS: This study confirmed the need to address the manner in which questions are framed to maximise patient disclosure. Responding to patent emotional cues was highlighted as an area for future training focus. PRACTICE IMPLICATIONS: Communication skills training that addresses each of these tasks is likely to improve the effectiveness of telephone-based delivery of supportive care.
