BackgroundWorkarounds circumvent or temporarily ‘fix’ perceived workflow hindrances to meet a goal or to achieve it more readily. Behaviours fitting the definition of workarounds often include violations, deviations, problem solving, improvisations, procedural failures and shortcuts. Clinicians implement workarounds in response to the complexity of delivering patient care. One imperative to understand workarounds lies in their influence on patient safety. This paper assesses the peer reviewed empirical evidence available on the use, proliferation, conceptualisation, rationalisation and perceived impact of nurses’ use of workarounds in acute care settings.MethodsA literature assessment was undertaken in 2011–2012. Snowballing technique, reference tracking, and a systematic search of twelve academic databases were conducted to identify peer reviewed published studies in acute care settings examining nurses’ workarounds. Selection criteria were applied across three phases. 58 studies were included in the final analysis and synthesis. Using an analytic frame, these studies were interrogated for: workarounds implemented in acute care settings by nurses; factors contributing to the development and proliferation of workarounds; the perceived impact of workarounds; and empirical evidence of nurses’ conceptualisation and rationalisation of workarounds.ResultsThe majority of studies examining nurses’ workarounds have been published since 2008, predominantly in the United States. Studies conducted across a variety of acute care settings use diverse data collection methods. Nurses’ workarounds, primarily perceived negatively, are both individually and collectively enacted. Organisational, work process, patient-related, individual, social and professional factors contribute to the proliferation of workarounds. Group norms, local and organisational culture, ‘being competent’, and collegiality influence the implementation of workarounds.ConclusionWorkarounds enable, yet potentially compromise, the execution of patient care. In some contexts such improvisations may be deemed necessary to the successful implementation of quality care, in others they are counterproductive. Workarounds have individual and cooperative characteristics. Few studies examine nurses’ individual and collective conceptualisation and rationalisation of workarounds or measure their impact. The importance of displaying competency (image management), collegiality and organisational and cultural norms play a role in nurses’ use of workarounds.
The evaluation of organ weights in toxicology studies is an integral component in the assessment of pharmaceuticals, chemicals, and medical devices. The Society of Toxicologic Pathology (STP) has created recommendations for weighing organs in GLP general toxicology studies lasting from 7 days to 1 year. The STP recommends that liver, heart, kidneys, brain, testes, and adrenal glands be weighed in all multidose general toxicology studies. Thyroid gland and pituitary gland weights are recommended for all species except mice. Spleen and thymus should be weighed in rodent studies and may be weighed in non-rodent studies. Weighing of reproductive organs is most valuable in sexually mature animals. Variability in age, sexual maturity, and stage of cycle in non-rodents and reproductive senescence in female rodents may complicate or limit interpretation of reproductive organ weights. The STP recommends that testes of all species be weighed in multidose general toxicology studies. Epididymides and prostate should be weighed in rat studies and may be weighed on a case-by-case basis in non-rodent and mouse studies. Weighing of other organs including female reproductive organs should be considered on a case-by-case basis. Organ weights are not recommended for any carcinogenicity studies including the alternative mouse bioassays. Regardless of the study type or organs evaluated, organ weight changes must be evaluated within the context of the compound class, mechanism of action, and the entire data set for that study.
The Society of Toxicologic Pathology convened a working group to evaluate current practices regarding organ weights in toxicology studies. A survey was distributed to pharmaceutical, veterinary, chemical, food/nutritional and consumer product companies in Europe, North America, and Japan. Responses were compiled to identify organs routinely weighed for various study types in rodent and non-rodent species, compare methods of organ weighing, provide perspectives on the value of organ weights and identify the scientist(s) responsible for organ weight data interpretation. Data were evaluated as a whole as well as by industry type and geographic location. Regulatory guidance documents describing organ weighing practices are generally available, however, they differ somewhat dependent on industry type and regulatory agency. While questionnaire respondents unanimously stated that organ weights were a good screening tool to identify treatment-related effects, opinions varied as to which organ weights are most valuable. The liver, kidneys, and testes were commonly weighed and most often considered useful by most respondents. Other organs that break were commonly weighed included brain, adrenal glands, ovaries, thyroid glands, uterus, heart, and spleen. Lungs, lymph nodes, and other sex organs were weighed infrequently in routine studies, but were often weighed in specialized studies such as inhalation, immunotoxicity, and reproduction studies. Organ-to-body weight ratios were commonly calculated and were considered more useful when body weights were affected. Organ to brain weight ratios were calculated by most North American companies, but rarely according to respondents representing veterinary product or European companies. Statistical analyses were generally performed by most respondents. Pathologists performed interpretation of organ weight data for the majority of the industries.
Background: Advocates for quality and safety have called for healthcare that is patient-centred and decision-making that involves patients. Objective: The aim of the paper is to explore the barriers and facilitators to patient-centred care in the hospital discharge process. Methods: A qualitative study using purposive sampling of 192 individual interviews and 26 focus group interviews was conducted in five European Union countries with patients and/or family members, hospital physicians and nurses, and community general practitioners and nurses. A modified Grounded Theory approach was used to analyse the data. Results: The barriers and facilitators were classified into 15 categories from which four themes emerged: (1) healthcare providers do not sufficiently prioritise discharge consultations with patients and family members due to time restraints and competing care obligations; (2) discharge communication varied from instructing patients and family members to shared decision-making; (3) patients often feel unprepared for discharge, and postdischarge care is not tailored to individual patient needs and preferences; and (4) pressure on available hospital beds and community resources affect the discharge process. Conclusions: Our findings suggest that involvement of patients and families in the preparations for discharge is determined by the extent to which care providers are willing and able to accommodate patients' and families' capabilities, needs and preferences. Future interventions should be directed at healthcare providers' attitudes and their organisation's leadership, with a focus on improving communication among care providers, patients and families, and between hospital and community care providers.
Purpose: Gastroesophageal adenocarcinoma (GEA) has a poor prognosis and few therapeutic options. Utilizing a 73gene plasma-based next-generation sequencing (NGS) cellfree circulating tumor DNA (ctDNA-NGS) test, we sought to evaluate the role of ctDNA-NGS in guiding clinical decisionmaking in GEA. Experimental Design: We evaluated a large cohort (n ¼ 2,140 tests; 1,630 patients) of ctDNA-NGS results (including 369 clinically annotated patients). Patients were assessed for genomic alteration (GA) distribution and correlation with clinicopathologic characteristics and outcomes. Results: Treatment history, tumor site, and disease burden dictated tumor-DNA shedding and consequent ctDNA-NGS maximum somatic variant allele frequency. Patients with locally advanced disease having detectable ctDNA postoperatively experienced inferior median disease-free survival (P ¼ 0.03). The genomic landscape was similar but not identical to tissue-NGS, reflecting temporospatial molecular heterogeneity, with some targetable GAs identified at higher frequency via ctDNA-NGS compared with previous primary tumor-NGS cohorts. Patients with known microsatellite instabilityhigh (MSI-High) tumors were robustly detected with ctDNA-NGS. Predictive biomarker assessment was optimized by incorporating tissue-NGS and ctDNA-NGS assessment in a complementary manner. HER2 inhibition demonstrated a profound survival benefit in HER2-amplified patients by ctDNA-NGS and/or tissue-NGS (median overall survival, 26.3 vs. 7.4 months; P ¼ 0.002), as did EGFR inhibition in EGFR-amplified patients (median overall survival, 21.1 vs. 14.4 months; P ¼ 0.01). Conclusions: ctDNA-NGS characterized GEA molecular heterogeneity and rendered important prognostic and predictive information, complementary to tissue-NGS.

IMPORTANCE Postoperative complications remain common after surgery, but little is known about the extent of variation in operative technical skill and whether variation is associated with patient outcomes.OBJECTIVES To examine the (1) variation in technical skill scores of practicing surgeons, (2) association between technical skills and patient outcomes, and (3) amount of variation in patient outcomes explained by a surgeon's technical skill. DESIGN, SETTING, AND PARTICIPANTSIn this quality improvement study, 17 practicing surgeons submitted a video of a laparoscopic right hemicolectomy that was then rated by at least 10 blinded peer surgeons and 2 expert raters. The association between surgeon technical skill scores and risk-adjusted outcomes was examined using data from the American College of Surgeons National Surgical Quality Improvement Program. The association between technical skill scores and outcomes was examined for colorectal procedures and noncolorectal procedures (ie, assessed on whether technical skills demonstrated during colectomy were associated with patient outcomes across other cases). In addition, the proportion of patient outcomes explained by technical skill scores was examined using robust regression techniques. The study was conducted from September 23, 2016, to February 10, 2018; data analysis was performed from November 2018 to January 2019. EXPOSURES Colorectal and noncolorectal procedures.MAIN OUTCOMES AND MEASURES Any complication, mortality, unplanned hospital readmission, unplanned reoperation related to principal procedure, surgical site infection, and death or serious morbidity. RESULTSOf the 17 surgeons included in the study, 13 were men (76%). The participants had a range from 1 to 28 years in surgical practice (median, 11 years). Based on 10 or more reviewers per video and with a maximum quality score of 5, overall technical skill scores ranged from 2.8 to 4.6. From 2014 to 2016, study participants performed a total of 3063 procedures (1120 colectomies). Higher technical skill scores were significantly associated with lower rates of any complication (15.5% vs 20.6%, P = .03; Spearman rank-order correlation coefficient r = −0.54, P = .03), unplanned reoperation (4.7% vs 7.2%, P = .02; r = −0.60, P = .01), and a composite measure of death or serious morbidity (15.9% vs 21.4%, P = .02; r = −0.60, P = .01) following colectomy. Similar associations were found between colectomy technical skill scores and patient outcomes for all types of procedures performed by a surgeon. Overall, technical skill scores appeared to account for 25.8% of the variation in postcolectomy complication rates and 27.5% of the variation when including noncolectomy complication rates. CONCLUSIONS AND RELEVANCEThe findings of this study suggest that there is wide variation in technical skill among practicing surgeons, accounting for more than 25% of the variation in patient outcomes. Higher colectomy technical skill scores appear to be associated with lower complication rates for colectomy and for all other pr...
