Concurrent Palliative Care for Surgical Patients

A common fallacy prevalent in surgical culture is for surgical intervention and palliation to be regarded as mutually exclusive or sequential strategies in the trajectory of surgical illness. Modern surgeons play a complex role as both providers and gatekeepers in meeting the palliative needs of their patients. Surgical palliative care is ideally delivered by surgical teams as a component of routine surgical care, and includes management of physical and psychosocial symptoms, basic communication about prognosis and treatment options, and identification of patient goals and values. Specialty palliative care services may be accessed through a through a variety of models.

The ageing joint-standard age- and sex-related values of bone erosions and osteophytes in the hand joints of healthy individuals

OBJECTIVE

To analyze the age-related changes of the physiological hand joint architecture.

METHOD

To address this concept, healthy individuals (each 10 women and 10 men in six different age decades spanning from 21 to 80 years) were recruited through a field campaign, investigated for the absence of rheumatic diseases and other comorbidities and received high-resolution quantitative computed tomography (HR-pQCT) examination of the hand joints. Number and extent of erosions and osteophytes were quantified across the ages and different sexes.

RESULTS

Bone erosions [median (Q1-Q3), 1 (0-2)] and osteophytes [2 (1-4)] were found in healthy women and men with no significant sex differences. Structural changes however accumulated with age: the overall incidence rate ratio (IRR) for the number of erosions and osteophytes per age were 1.04 (95% CI: erosions 1.03-1.06; osteophytes: 1.03-1.05). This means a 4% increase in the number of erosions and osteophytes per year. Using third decade as reference, healthy individuals in the age decades from 50 years had higher IRR for erosion numbers (sixth, seventh, eigth decade: 4.87 (2.20-11.75), 6.81 (3.08-16.46) and 6.92 (3.11-16.79)) compared to younger subjects (fourth, fifth decade: 1.80 (0.69-4.87), 1.53 (0.59-4.10)). The IRRs of osteophytes also indicate a gradual increase after the fifth decade, with IRRs of 2.32 (1.32-4.17), 4.17 (2.38-7.49) and 6.86 (3.97-12.20) for the sixth, seventh and eigth decades, respectively.

CONCLUSIONS

Structural changes in the hand joints of healthy individuals are age dependent. While being rare under 50 years of age, erosions and osteophytes accumulate above the age of 50, suggesting that the threshold between "normal" and "pathological" is shifted with the increase of age.

A historical cohort study on glycemic-control and cancer-risk among patients with diabetes

AIMS

This population-based historical cohort study examined whether poor glycemic-control (i.e., high glucose and HbA1c blood levels) in patients with diabetes is associated with cancer-risk.

METHODS

From a large healthcare database, patients aged 21-89 years, diagnosed with diabetes before January 2002 (prevalent) or during 2002-2010 (incident), were followed for cancer during 2004-2012 (excluding cancers diagnosed within the first 2 years since diabetes diagnosis). Risks of selected cancers (all-sites, colon, breast, lung, prostate, pancreas and liver) were estimated according to glycemic-control in a Cox regression model with time-dependent covariates, adjusted for age, sex, ethnic origin, socioeconomic status, smoking and parity. Missing glucose or HbA1c values were imputed.

RESULTS

Among 440,000 patients included in our analysis, cancer was detected more than 2 years after diabetes diagnosis in 26,887 patients (6%) during the follow-up period. Associations of poor glycemic-control with all-sites cancer and most specific cancers were either null or only weak (hazard ratios (HRs) for a 1% HbA1c or a 30 mg/dl glucose increase between 0.94 and 1.09). Exceptions were pancreatic cancer, for which there was a strong positive association (HRs: 1.26-1.51), and prostate cancer, for which there was a moderate negative association (HRs: 0.85-0.96).

CONCLUSION

Overall, poor glycemic-control appears to be only weakly associated with cancer-risk, if at all. A substantial part of the positive association with pancreatic cancer is attributable to reverse causation, with the cancer causing poorer glycemic-control prior to its diagnosis. The negative association with prostate cancer may be related to lower PSA levels in those with poor control.

Establishing Goals of Care for Patients With Stroke and Feeding Problems: An Interdisciplinary Trigger-Based Continuous Quality Improvement Project

BACKGROUND

Few patients with dysphagia because of stroke receive early palliative care (PC) to align treatment goals with their values, as called for by practice guidelines, particularly before enteral access procedures for artificial nutrition.

MEASURES

To increase documented goals of care (GOC) discussions among acute stroke patients before feeding gastrostomy tube placement.

INTERVENTION

We undertook a rapid-cycle continuous quality improvement process with interdisciplinary planning, implementation, and performance review to operationalize an upstream trigger for PC referral prompted by the speech and language pathology evaluation.

OUTCOMES

During a six-month period, 21 patients underwent gastrostomy tube placement; 52% had preprocedure GOC discussions postintervention, with the rate of compliance increasing steadily from 13% (11/87, preintervention) to 100% (2/2) in the final two months.

CONCLUSIONS/LESSONS LEARNED

We effectively increased documented GOC discussions before feeding gastrostomy tube placement among stroke patients. Systems-based tools and education will enhance this upstream trigger model to ensure early PC for stroke patients.

Flipping social determinants on its head: Medical student perspectives on the flipped classroom and simulated patients to teach social determinants of health

BACKGROUND

Inequalities in healthcare are increasing. Engaging medical students to tackle this urgent challenge alongside clinical sciences can be demanding. This study examines medical student perceptions of a flipped approach to health inequalities co-designed by faculty and sixth-year students.

INNOVATION

A flipped learning session was piloted for year 4 medical students combining an online lesson followed by a tutorial with a simulated patient.

METHODS

A mixed-methods approach collected questionnaire data using 4-point Likert scales and free text answers. A semi-structured group interview was conducted with six voluntary participants.

RESULTS

Two hundred and eighty-nine students completed questionnaires. 85% (n = 246) completed the online lesson. Students agreed the session helped their understanding of key concepts (mean 3.2), was improved by having an actor (mean = 3.6), and was enjoyable (mean = 3.2). Thematic analysis of qualitative questionnaire and interview data revealed three themes: engagement; structure; and attitudes towards social determinants of health. The simulation increased clinical relevance and students gained understanding of the impact of health inequalities upon individuals.

CONCLUSIONS

This paper indicates flipped learning can increase clinical relevance and engagement in population health and person-centered care. Further work could assess changes in practice and attitudes of future doctors in tackling such global health challenges.

Outcomes and palliative care utilization in patients with dementia and acute abdominal emergency: opportunities for surgical quality improvement

BACKGROUND

When patients with dementia develop acute surgical abdomen, patients, surrogates, and surgeons need accurate prognostic information to facilitate goal-concordant decision making. Palliative care can assist with communication, symptom management, and family and caregiver support in this population. We aimed to characterize outcomes and patterns of palliative care utilization among patients with dementia, presenting with abdominal surgical emergency.

METHOD

We retrospectively queried the National Inpatient Sample for patients aged >50 years with dementia and acute abdominal emergency who were admitted nonelectively 2009-2013, utilizing ICD-9-CM codes for dementia and surgical indication. We characterized outcomes and identified predictors of palliative care utilization.

RESULTS

Among 15,209 patients, in-hospital mortality was 10.2%, the nonroutine discharge rate was 67.2%, and 7.5% received palliative care. Patients treated operatively were less likely to receive palliative care than those who did not undergo operation (adjusted OR = 0.50; 95% CI 0.41-0.62). Only 6.4% of patients discharged nonroutinely received palliative care.

CONCLUSION

Patients with dementia and acute abdominal emergency have considerable in-hospital mortality, a high frequency of nonroutine discharge, and low palliative care utilization. In this group, we discovered a large gap in palliative care utilization, particularly among those treated operatively and those who are discharged nonroutinely.

Goals of Care and End of Life in the ICU

Despite advances in surgical critical care, critical illness remains traumatic and has long-term adverse sequelae. Unrealistic expectations and erroneous assumptions about outcomes acceptable to patients have been identified as drivers of goal-discordant treatment. Goal setting in the ICU begins with compassionately delivered, accurate, and honest prognostic information. Through skilled communication and shared decision making, clinicians forge a mutual understanding of patient values and priorities and the role of therapeutic options in achieving patient goals. Ensuring that treatment is goal-concordant and meets physical, psychosocial, existential, and spiritual needs is crucial for attaining optimal patient and caregiver outcomes, independent of survival.

Navigating high-risk surgery: protocol for a multisite, stepped wedge, cluster-randomised trial of a question prompt list intervention to empower older adults to ask questions that inform treatment decisions

INTRODUCTION

Older patients frequently undergo operations that carry high risk for postoperative complications and death. Poor preoperative communication between patients and surgeons can lead to uninformed decisions and result in unexpected outcomes, conflict between surgeons and patients, and treatment inconsistent with patient preferences. This article describes the protocol for a multisite, cluster-randomised trial that uses a stepped wedge design to test a patient-driven question prompt list (QPL) intervention aimed to improve preoperative decision making and inform postoperative expectations.

METHODS AND ANALYSIS

This Patient-Centered Outcomes Research Institute-funded trial will be conducted at five academic medical centres in the USA. Study participants include surgeons who routinely perform vascular or oncological surgery, their patients and families. We aim to enrol 40 surgeons and 480 patients over 24 months. Patients age 65 or older who see a study-enrolled surgeon to discuss a vascular or oncological problem that could be treated with high-risk surgery will be enrolled at their clinic visit. Together with stakeholders, we developed a QPL intervention addressing preoperative communication needs of patients considering major surgery. Guided by the theories of self-determination and relational autonomy, this intervention is designed to increase patient activation. Patients will receive the QPL brochure and a letter from their surgeon encouraging its use. Using audio recordings of the outpatient surgical consultation, patient and family member questionnaires administered at three time points and retrospective chart review, we will compare the effectiveness of the QPL intervention to usual care with respect to the following primary outcomes: patient engagement in decision making, psychological well-being and post-treatment regret for patients and families, and interpersonal and intrapersonal conflict relating to treatment decisions and treatments received.

ETHICS AND DISSEMINATION

Approvals have been granted by the Institutional Review Board at the University of Wisconsin and at each participating site, and a Certificate of Confidentiality has been obtained. Results will be reported in peer-reviewed publications and presented at national meetings.

TRIAL REGISTRATION NUMBER

NCT02623335.

Prostate magnetic resonance imaging for brachytherapists: Diagnosis, imaging pitfalls, and post-therapy assessment

Optimal integration of multiparametric MRI (mp MRI) into prostate brachytherapy practice necessitates an understanding of imaging findings pertinent to prostate cancer detection and staging. This review will summarize prostate cancer imaging findings and tumor staging on mp MRI, including an overview of the Prostate Imaging Reporting and Data System (PIRADS)-structured reporting schema, mp MRI findings observed in the post-therapy setting including cases of post-treatment recurrence, and MRI concepts integral to successful salvage brachytherapy.

Perioperative goal-setting consultations by surgical colleagues: a new model for supporting patients, families, and surgeons in shared decision making

Patients with postoperative complications are often subjected to prolonged life-sustaining treatment based on erroneous assumptions about their goals of care. Shared decision making (SDM) is an evidence-based approach that helps ensure patients' wishes and values are honored in their course of treatment. Perioperative palliative care can help create goal-concordant trajectories of care for high risk, seriously ill, or complicated patients, through sophisticated prognostication, higher-level communication, and recommendations based on the best available evidence and patients' stated goals and priorities. Here, we present a surgeon-to-surgeon consultative model that surmounts many barriers to perioperative palliative care consultation and, as illustrated in the cases presented herein, offers profound and unique benefits for patients, families, and surgeons alike. While the support of a surgical colleague with palliative care skills can be helpful postoperatively in the setting of unanticipated outcomes or prolonged recovery, it is particularly beneficial when accessed preoperatively for the purposes of goal-concordant decision making and advance care planning. We encourage both individuals and professional societies to develop and expand the niche for surgeons interested in assisting with goal setting and SDM for patients on a consultative basis, particularly in the preoperative period.

Isolate Specificity and Polygenic Inheritance of Resistance in Barley to the Heterologous Rust Pathogen Puccinia graminis f. sp. avenae

Barley is a near-nonhost to numerous heterologous (nonadapted) rust pathogens because a small proportion of genotypes are somewhat susceptible. We assessed 66 barley accessions and three mapping populations (Vada × SusPtrit, Cebada Capa × SusPtrit, and SusPtrit × Golden Promise) for response to three Swedish oat stem rust (Puccinia graminis f. sp. avenae) fungal isolates and determined that barley is a near-nonhost to P. graminis f. sp. avenae and that resistance was polygenically inherited. The parental genotypes Vada and Golden Promise were immune to all three isolates, whereas Cebada Capa was immune to two isolates and moderately resistant to the third. Phenotypic data from the Vada × SusPtrit mapping population and the barley accessions tested also demonstrated isolate-specific resistance. In particular, the SusPtrit parent and several other accessions allowed sporulation by isolate Ingeberga but were resistant to isolate Evertsholm. Nine chromosomal regions carried quantitative trait loci (QTL) (Rpgaq1 to Rpgaq9) of varying effect, most of which colocated to previously identified QTL for resistance to other heterologous rust pathogens. Rpgaq1 on chromosome 1H (Vada and Golden Promise) was effective toward all isolates tested. Microscopic examination indicated that resistance was prehaustorial in Vada whereas, in SusPtrit, both pre- and posthaustorial mechanisms play a role.

Assessing Emotional Suffering in Palliative Care: Use of a Structured Note Template to Improve Documentation

CONTEXT

Documentation of the emotional or psychological needs of seriously ill patients receiving specialty palliative care is endorsed by the "Measuring What Matters" project as a quality performance metric and recommended for use by hospice and palliative care programs for program improvement.

OBJECTIVES

The aim of this study was to increase the proportion of inpatient palliative care team encounters in which emotional or psychological needs of patients and family members were documented and to qualitatively enrich the nature of this documentation.

METHODS

This is a mixed-methods retrospective study of 200 patient charts reviewed before and after implementation of a structured note template (SmartPhrase) for palliative care encounters. Patterns of documentation of emotional needs pre- and post-implementation were assessed quantitatively and qualitatively using thematic analysis.

RESULTS

A total of 158 of 200 pre-intervention charts and 185 of 200 post-intervention charts included at least one note from the palliative care team. Documentation of emotional assessment increased after SmartPhrase implementation (63.9% [101 of 158] vs. 74.6% [138 of 185]; P < 0.03). Qualitative analysis revealed a post-intervention reduction in the use of generic phrases ("emotional support provided") and an increase in the breadth and depth of emotion-related documentation.

CONCLUSION

A structured note template with a prompt for emotional assessment increases the overall quantity and richness of documentation related to patient and family emotions. However, this documentation remains mostly descriptive. Additional prompting for documentation of recommendations to address identified emotional needs, and the use of screening tools for depression and anxiety, when appropriate, may be necessary for clinically meaningful quality improvements in patient care.

A Heart Set on Living

Quality of life is a highly subjective element on which to base health care decision making. This narrative reflection after the death of a family member uses poetry as a prompt to explore themes related to quality of life-including symptom burden, interpersonal relationships in the face of illness, and the will to live. Through penetrating inquiry and reflection, physicians and other care providers can gain insight into the underlying motivations, loyalties, and abilities that lend meaning to patients' lives and shape attitudes toward death and dying. By better recognizing and appreciating these factors, clinicians can develop patient-centered quality-of-life constructs that empower them to honor patient goals and preferences at the end of life. Physicians are encouraged to explore poetry and other artistic media to help foster the reflective capacity required to deeply understand and faithfully serve patients in this regard.

Palliative Care Interventions for Surgical Patients: A Systematic Review

IMPORTANCE

Inpatient palliative care improves symptom management and patient satisfaction with care and reduces hospital costs in seriously ill patients. However, the role of palliative care in the treatment of patients undergoing surgery (surgical patients) remains poorly defined.

OBJECTIVE

To characterize the content, design, and results of interventions to improve access to palliative care or the quality of palliative care for surgical patients.

EVIDENCE REVIEW

This systematic review was conducted according to PRIMSA guidelines. Articles were identified through searches of PubMed, PsycINFO, EMBASE, and CINAHL as well as manual review of references. Eligible articles included experimental, quasi-experimental, and observational studies published in English from January 1, 1994, through October 31, 2014, in which patient outcomes of palliative care interventions for adult surgical patients were reported. Data on the study setting, design, intervention, participants, and results were extracted from the final study set and analyzed from December 22, 2014, to February 7, 2015.

FINDINGS

A total of 3838 abstracts were identified and screened by 2 reviewers, 77 articles were reviewed in full text, and 25 articles (22 unique interventions involving 8575 unique patients) met the study criteria. Interrater agreement was good (κ = 0.78). Nine single-institution retrospective cohort studies, 7 single-institution prospective cohort studies, 7 single-institution randomized clinical studies, and 2 multicenter randomized clinical studies were included. Nineteen of the 23 single-site studies were performed at academic hospitals. Given the heterogeneity of study methods and measures, meta-analysis was not possible. Preoperative decision-making interventions were associated with decreased mortality in 4 studies. Three studies reported improved quality of communication; 4, improved symptom management; and 7, decreased use of health care resources and decreased cost. However, many studies were small, performed in academic settings, and methodologically flawed and did not measure clinically meaningful outcomes.

CONCLUSIONS AND RELEVANCE

The sparse evidence regarding interventions to introduce or improve palliative care for surgical patients is further limited by methodologic flaws. Rigorous evaluations of standardized palliative care interventions measuring meaningful patient outcomes are needed.

Risk factors for and impact of carbapenem-resistant Acinetobacter baumannii colonization and infection: matched case-control study

The objective of this investigation was to identify risk factors for carbapenem-resistant Acinetobacter baumannii (CRAB) and its association with mortality. A population-based matched case-control study using the computerized database of Clalit Health Services (CHS) in the period between 2007 and 2012 was conducted. Hospitalized patients with CRAB colonization or infection were compared to hospitalized patients without evidence of A. baumannii, matched by age, ward of hospitalization, season, Charlson score, and length of hospitalization. Risk factors for CRAB isolation were searched for using multivariate analysis. Association of CRAB and other risk factors with mortality were assessed in the cohort. A total of 1190 patients with CRAB were matched to 1190 patients without CRAB. Low socioeconomic status was independently associated with CRAB isolation and CRAB bacteremia [odds ratio 2.18, 95% confidence interval (CI) 1.02-5]. Other risk factors were invasive procedures and bacteremia with other pathogens prior to CRAB isolation, and various comorbidities. Among all patients, CRAB isolation was independently associated with increased mortality (hazard ratio 2.33, 95% CI 2.08-2.6). Socioeconomic status is associated with health outcomes. Our population-based study revealed an almost doubled risk for CRAB in patients at lower socioeconomic status and an association with healthcare exposure. CRAB was associated with mortality and might become a risk indicator for complex morbidity and mortality.

Measurement of the charged-pion polarizability

The COMPASS collaboration at CERN has investigated pion Compton scattering, π(-)γ→π(-)γ, at center-of-mass energy below 3.5 pion masses. The process is embedded in the reaction π(-)Ni→π(-)γNi, which is initiated by 190 GeV pions impinging on a nickel target. The exchange of quasireal photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, Q(2)<0.0015  (GeV/c)(2). From a sample of 63,000 events, the pion electric polarizability is determined to be α(π)=(2.0±0.6(stat)±0.7(syst))×10(-4)  fm(3) under the assumption α(π)=-β(π), which relates the electric and magnetic dipole polarizabilities. It is the most precise measurement of this fundamental low-energy parameter of strong interaction that has been addressed since long by various methods with conflicting outcomes. While this result is in tension with previous dedicated measurements, it is found in agreement with the expectation from chiral perturbation theory. An additional measurement replacing pions by muons, for which the cross-section behavior is unambiguously known, was performed for an independent estimate of the systematic uncertainty.

N(1520) 3/2(-) helicity amplitudes from an energy-independent multipole analysis based on new polarization data on photoproduction of neutral pions

New data on the polarization observables T, P, and H for the reaction γp→pπ(0) are reported. The results are extracted from azimuthal asymmetries when a transversely polarized butanol target and a linearly polarized photon beam are used. The data were taken at the Bonn electron stretcher accelerator ELSA using the CBELSA/TAPS detector. These and earlier data are used to perform a truncated energy-independent partial wave analysis in sliced-energy bins. This energy-independent analysis is compared to the results from energy-dependent partial wave analyses.

An arranged marriage for precision medicine: hypoxia and genomic assays in localized prostate cancer radiotherapy

Prostate cancer (CaP) is the most commonly diagnosed malignancy in males in the Western world with one in six males diagnosed in their lifetime. Current clinical prognostication groupings use pathologic Gleason score, pre-treatment prostatic-specific antigen and Union for International Cancer Control-TNM staging to place patients with localized CaP into low-, intermediate- and high-risk categories. These categories represent an increasing risk of biochemical failure and CaP-specific mortality rates, they also reflect the need for increasing treatment intensity and justification for increased side effects. In this article, we point out that 30-50% of patients will still fail image-guided radiotherapy or surgery despite the judicious use of clinical risk categories owing to interpatient heterogeneity in treatment response. To improve treatment individualization, better predictors of prognosis and radiotherapy treatment response are needed to triage patients to bespoke and intensified CaP treatment protocols. These should include the use of pre-treatment genomic tests based on DNA or RNA indices and/or assays that reflect cancer metabolism, such as hypoxia assays, to define patient-specific CaP progression and aggression. More importantly, it is argued that these novel prognostic assays could be even more useful if combined together to drive forward precision cancer medicine for localized CaP.

Rust Fungi Forming Aecia on Berberis spp. in Sweden

Barberry (Berberis spp.) hosts the aecial stage of several rust species, including Puccinia graminis, which causes stem rust on grasses and cereals. The aecial stage of this pathogen has received less attention because it is not as economically important compared with the uredinial and telial stages. The main objective of this study was to identify and describe the rust species that were found on Berberis spp. collected in different parts of Sweden. A morphological study, including spore measurements and aecia descriptions, was conducted, as well as DNA sequence analyses (using the internal transcribed spacer region and the EF1-α gene). Based on spore and aecia morphology as well as the genetic analyses, three different taxa could be distinguished on barberry: P. graminis f. sp. avenae, P. graminis f. sp. tritci/secalis, and P. arrhenatheri. The genetic analysis revealed little or no differentiation between P. graminis f. sp. tritici and P. graminis f. sp. secalis and, thus, this group of samples was denominated P. graminis f. sp. tritici/secalis. Aecial morphology may be used to differentiate between different taxa. In particular, examination of aecial cross-sections may be used to distinguish between P. graminis f. sp. avenae and P. graminis f. sp. tritici/secalis. A clear differentiation in the mode of growth on barberry was also found; P. arrhenatheri always appeared systemic whereas P. graminis always appeared localized.

Alternate monolayers of CdSe nanocrystals and perylene tetracarboxylate: quantum dot hypersensitization for dye-sensitized solar cells

Mono- and multilayers from CdSe nanocrystal dispersion and perylene tetracarboxylate solution are reported for the first time. The layers were investigated by UV-visible spectroscopy, cyclic voltammetry, photoconductivity, and photoelectrochemical techniques. The n-type organic semiconductor gives enhanced photoconductivity to the CdSe-NC multilayer structure. The photoactive perylene monolayer acts also as hypersensitizer of CdSe-NC structures. The perylene-modified CdSe-NC monolayer on indium tin oxide (ITO) electrode in a three-electrode photoelectrochemical cell upon illumination in the presence of oxygen generates an intense steady photocurrent as high as 10-20 times that expected from the individual contributions of perylene and CdSe-NCs. The hypersensitization mechanism is discussed on the basis of the energy level diagram of the components.

AMDIS Case Conference: Implementing Electronic Health Records in a Small Subspecialty Practice

Electronic health record adoption has failed to achieve critical mass in small private practices in no small part due to lack of leadership; the challenge of cultural change; and the difficulty of adapting to new automated workflows. We present one small practice that successfully navigated these obstacles, and examine its accomplishments through the lens of organizational psychology.
