Outpatient parenteral antimicrobial therapy (OPAT) across the world: a comparative analysis-what lessons can we learn?

This paper presents a comparative analysis of Outpatient Parenteral Antimicrobial Therapy (OPAT) structures and delivery options across different countries. OPAT, a cost-effective alternative to inpatient care for patients requiring IV antimicrobial therapy, has demonstrated multiple benefits such as patient satisfaction, economic cost savings, and reduced hospital-acquired infections. Despite these advantages, there is considerable international variation in OPAT use and implementation.

A qualitative study examining young peoples' perceptions and adherence to COVID-19 public health guidelines in Ireland.

Background: Public health measures are the main intervention to stop the spread of COVID-19. They rely on the adherence to everyday health behaviors, and depend on those at high and low personal risk of serious disease to comply. Young people are crucial to stemming community transmission, and are often living in shared housing and at a stage of their lives with more economic uncertainty than older groups.

Translating evidence in a priority setting partnership: knowledge gaps between healthcare providers and oesophageal cancer patients.

Introduction: Despite the fact that health information is now more accessible than ever, knowledge gaps remain between patients and healthcare providers (HCPs). To date, the patients' need for information following a diagnosis of oesophageal cancer has not been adequately met.

Purpose: The purpose of this study was to identify why knowledge gaps exist between oesophageal cancer patients and HCPs and how to address them.

The Effect of the 2009 USPSTF breast cancer screening recommendations on breast cancer in Michigan: A longitudinal study.

In 2009, the revised United States Preventive Services Task Force (USPSTF) guidelines recommended against routine screening mammography for women age 40-49 years and against teaching self-breast examinations (SBE). The aim of this study was to analyze whether breast cancer method of presentation changed following the 2009 USPSTF screening recommendations in a large Michigan cohort. Data were collected on women with newly diagnosed stage 0-III breast cancer participating in the Michigan Breast Oncology Quality Initiative (MiBOQI) registry at 25 statewide institutions from 2006 to 2015.

Variation in the use of advanced imaging at the time of breast cancer diagnosis in a statewide registry.

Background: Although national guidelines do not recommend extent of disease imaging for patients with newly diagnosed early stage breast cancer given that the harm outweighs the benefits, high rates of testing have been documented. The 2012 Choosing Wisely guidelines specifically addressed this issue. We examined the change over time in imaging use across a statewide collaborative, as well as the reasons for performing imaging and the impact on cost of care.

Associations between use of the 21-gene recurrence score assay and chemotherapy regimen selection in a statewide registry.

Background: The 21-gene recurrence score (RS) assay predicts response to adjuvant chemotherapy in patients with early-stage, hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative invasive breast cancer, but to the authors' knowledge, the role of the assay in guiding the selection of chemotherapy regimen has not been established. The current study was conducted to examine patterns of use of the RS assay for selecting chemotherapy regimens across a statewide registry from 2006 through 2013.

Methods: Demographic, pathologic, and treatment data were abstracted from medical records for 16,666 women with breast cancer who were treated at 25 hospital systems across Michigan that were participating in the Michigan Breast Oncology Quality Initiative.

Biological Subtype Predicts Risk of Locoregional Recurrence After Mastectomy and Impact of Postmastectomy Radiation in a Large National Database.

Purpose: To evaluate locoregional recurrence (LRR) after mastectomy and impact of postmastectomy radiation (PMRT) by breast cancer subtype.

Methods And Materials: Between 2000 and 2009, 5673 patients with stage I to III breast carcinoma underwent mastectomy and nodal evaluation; 30% received PMRT. Isolated LRR (iLRR) and LRR were compared across groups defined by biological subtype and receipt of trastuzumab: luminal A (estrogen [ER]/progesterone [PR]+, HER2-, low/intermediate grade), luminal B (ER/PR+, HER2-, high grade), HER2 with trastuzumab, HER2 without trastuzumab, and triple negative (TN; ER-, PR-, HER2-).

University of Michigan Comprehensive Cancer Center opportunities for improvement project.

The University of Michigan Comprehensive Cancer Center (UMCCC) Opportunities for Improvement project involved a detailed patient-level medical record review, feedback to medical providers and clinical leadership, and discussion of potential predictors of discordant or delayed care. The medical record review revealed that reasons for discordant or delayed care were well documented by clinical providers, and medical comorbidity was the most common predisposing factor. Another common theme was the difficulty in obtaining treatment records for patients who received a portion of their care outside UMCCC.

Implementing distress management guidelines in ambulatory oncology: a quality improvement project.

Distress assessment and referral to psychosocial services is an essential component of evidence-based oncologic nursing care. Oncology nurses have an opportunity to address patient distress needs through leadership of implementation programs and support for the positive outcomes that engaging in psychosocial services provides. This quality improvement project was conducted to evaluate the feasibility and utility of the National Comprehensive Cancer Network's distress management clinical practice guidelines in ambulatory oncology.

Time to adjuvant chemotherapy for breast cancer in National Comprehensive Cancer Network institutions.

Background: High-quality care must be not only appropriate but also timely. We assessed time to initiation of adjuvant chemotherapy for breast cancer as well as factors associated with delay to help identify targets for future efforts to reduce unnecessary delays.

Methods: Using data from the National Comprehensive Cancer Network (NCCN) Outcomes Database, we assessed the time from pathological diagnosis to initiation of chemotherapy (TTC) among 6622 women with stage I to stage III breast cancer diagnosed from 2003 through 2009 and treated with adjuvant chemotherapy in nine NCCN centers.

Trends in advanced imaging use for women undergoing breast cancer surgery.

Background: Evidence-based guidelines recommend limited perioperative diagnostic imaging for new breast cancer diagnoses. For patients aged >65 years, conventional imaging use (mammography, plain radiographs, and ultrasound) has remained stable, whereas advanced imaging (computed tomography [CT], nuclear medicine scans [positron emission tomography/bone scans], and magnetic resonance imaging [MRI]) use has increased. In this study, the authors evaluated traditional and advanced imaging use among younger patients (aged ≤ 65 years) undergoing breast cancer surgery.

Intraoperative frozen section analysis of margins in breast conserving surgery significantly decreases reoperative rates: one-year experience at an ambulatory surgical center.

Intraoperative frozen section (FS) margin evaluation is not common practice for patients undergoing breast conservation therapy (BCT), but offers a significant reduction in reoperation. In this study, a technique to allow for more effective freezing of breast tissue was developed to perform FS evaluation of lumpectomy margins (FSM) for all patients undergoing BCT at an ambulatory surgery center. FS evaluation of sentinel lymph node biopsy specimens was performed concurrently.

Is duct excision still necessary for all cases of suspicious nipple discharge?

Despite the low likelihood of malignancy, it is recommended that all women with pathologic nipple discharge undergo duct excision based on the inadequate sensitivity of diagnostic modalities. However, these data originates prior to recent improvements in breast imaging. We performed a retrospective review of patients evaluated in the setting of modern diagnostic breast imaging.

Development of an intraoperative pathology consultation service at a free-standing ambulatory surgical center: clinical and economic impact for patients undergoing breast cancer surgery.

Background: Second surgeries represent a significant detriment to breast cancer patients. We examined the impact an intraoperative pathology consultation service had on multiple facets of breast cancer surgery.

Methods: We compared the 8 months before the establishment of a pathology laboratory, when intraoperative pathology consultation was not available, with the 8 months subsequent, when it was performed routinely.

Improving breast cancer care through a regional quality collaborative.

Background: Regional collaborative organizations provide an effective structure for improving the quality of surgical care. With low complication rates and a long latency between surgical care and outcomes such as survival and local recurrence, quality measurement in breast cancer surgery is ideally suited to process measures. Diagnostic biopsy technique for breast cancer diagnosis is measurable and amenable to change at the provider level.

Hospital factors and racial disparities in mortality after surgery for breast and colon cancer.

Purpose: Black patients have worse prognoses than whites with breast or colorectal cancer. Mechanisms underlying such disparities have not been fully explored. We examined the role of hospital factors in racial differences in late mortality after surgery for breast or colon cancer.

Determinants of breast conservation rates: reasons for mastectomy at a comprehensive cancer center.

Bias in referral patterns and variations in multi-disciplinary management may impact breast conservation therapy (BCT) rates between hospitals. Retrospective studies of BCT rates are limited by their inability to differentiate indicated mastectomies versus those chosen by the patient. Our prospective breast cancer data base was queried for patients with invasive breast cancer who underwent surgical therapy at the University of Michigan over a 3-year period.

Residual disease after re-excision lumpectomy for close margins.

Introduction: While a positive margin after an attempt at breast conservation therapy (BCT) is a reason for concern, there is more controversy regarding close margins. When re-excisions are performed, there is often no residual disease in the new specimen, calling into question the need for the procedure. We sought to examine the incidence of residual disease after re-excision for close margins and to identify predictive factors that may better select patients for re-excision.

Exploring the effect of the referring general surgeon's attitudes on breast reconstruction utilization.

Background: Breast reconstruction rates remain low, at 5%-15% of mastectomy patients, despite the safety and high patient satisfaction of these procedures. Reasons for this are multifactorial, including the attitudes and biases of the referring breast surgeon, as well as patient factors. The purpose of this study was to explore attitudes of general surgeons towards breast reconstruction.

Model based and empirical spectral analysis for the diagnosis of breast cancer.

We explored the use of both empirical (Partial Least Squares, PLS) and Monte Carlo model based approaches for the analysis of fluorescence and diffuse reflectance spectra measured ex vivo from freshly excised breast tissues and for the diagnosis of breast cancer. Features extracted using both approaches, i.e.

Diagnosis of breast cancer using fluorescence and diffuse reflectance spectroscopy: a Monte-Carlo-model-based approach.

We explore the use of Monte-Carlo-model-based approaches for the analysis of fluorescence and diffuse reflectance spectra measured ex vivo from breast tissues. These models are used to extract the absorption, scattering, and fluorescence properties of malignant and nonmalignant tissues and to diagnose breast cancer based on these intrinsic tissue properties. Absorption and scattering properties, including beta-carotene concentration, total hemoglobin concentration, hemoglobin saturation, and the mean reduced scattering coefficient are derived from diffuse reflectance spectra using a previously developed Monte Carlo model of diffuse reflectance.

A large-scale study of the ultrawideband microwave dielectric properties of normal, benign and malignant breast tissues obtained from cancer surgeries.

The development of microwave breast cancer detection and treatment techniques has been driven by reports of substantial contrast in the dielectric properties of malignant and normal breast tissues. However, definitive knowledge of the dielectric properties of normal and diseased breast tissues at microwave frequencies has been limited by gaps and discrepancies across previously published studies. To address these issues, we conducted a large-scale study to experimentally determine the ultrawideband microwave dielectric properties of a variety of normal, malignant and benign breast tissues, measured from 0.

Surgical work output: is there room for increase? An analysis of surgical work effort from 1999 to 2003.

Objective: To analyze physician work production over a 5-year period to discover trends in productivity.

Summary Background Data: Surgical workforce calculations over the past 25 years have projected major oversupply as well as looming shortages. Recent studies indicate that demand for surgical services will increase over the next two decades as the population ages and develops age related chronic diseases.
