Conceptualising social media addiction: a longitudinal network analysis of social media addiction symptoms and their relationships with psychological distress in a community sample of adults.

BACKGROUND: Problematic social media use has been identified as negatively impacting psychological and everyday functioning and has been identified as a possible behavioural addiction (social media addiction; SMA). Whether SMA can be classified as a distinct behavioural addiction has been debated within the literature, with some regarding SMA as a premature pathologisation of ordinary social media use behaviour and suggesting there is little evidence for its use as a category of clinical concern. This study aimed to understand the relationship between proposed symptoms of SMA and psychological distress and examine these over time in a longitudinal network analysis, in order better understand whether SMA warrants classification as a unique pathology unique from general distress. METHOD: N = 462 adults (Mage = 30.8, SDage = 9.23, 69.3% males, 29% females, 1.9% other sex or gender) completed measures of social media addiction (Bergen Social Media Addiction Scale), and psychological distress (DASS-21) at two time points, twelve months apart. Data were analysed using network analysis (NA) to explore SMA symptoms and psychological distress. Specifically, NA allows to assess the 'influence' and pathways of influence of each symptom in the network both cross-sectionally at each time point, as well as over time. RESULTS: SMA symptoms were found to be stable cross-sectionally over time, and were associated with, yet distinct, from, depression, anxiety and stress. The most central symptoms within the network were tolerance and mood-modification in terms of expected influence and closeness respectively. Depression symptoms appeared to have less of a formative effect on SMA symptoms than anxiety and stress. CONCLUSIONS: Our findings support the conceptualisation of SMA as a distinct construct occurring based on an underpinning network cluster of behaviours and a distinct association between SMA symptoms and distress. Further replications of these findings, however, are needed to strengthen the evidence for SMA as a unique behavioural addiction.

Unbundling Bundles: Evaluating the Association of Individual Colorectal Surgical Site Infection Reduction Bundle Elements on Infection Rates in a Statewide Collaborative.

BACKGROUND: Surgical site infection reduction bundles are effective but can be complex and resource intensive. Understanding which bundle elements are associated with reduced surgical site infections may guide concise bundle implementation. OBJECTIVE: The purpose of this study was to evaluate the association of individual surgical site infection reduction bundle elements with infection rates. DESIGN: This was a post-hoc analysis of a prospective cohort study. SETTING: This study took place at Illinois Surgical Quality Improvement Collaborative hospitals. PATIENTS: Patients who had elective colorectal resections at participating hospitals from 2016 to 2017. INTERVENTIONS: The intervention was a 16-element colorectal surgical site infection reduction bundle. MAIN OUTCOME MEASURES: Surgical site infection rates were compared among patients by adherence with each bundle element using χ 2 tests and multivariable logistic regression. Principal component analysis identified composites of correlated bundle elements. Coincidence analysis identified combinations of bundle elements or principal component composites associated with the absence of surgical site infection. RESULTS: Among 2722 patients, 192 (7.1%) developed a surgical site infection. Infections were less likely when oral antibiotics (OR 0.63 [95% CI 0.41-0.97]), wound protectors (OR 0.55 [95% CI 0.37-0.81]), and occlusive dressings (OR 0.71 [95% CI 0.51-1.00]) were used. Bundle elements were reduced into 5 principal component composites. Adherence with the combination of oral antibiotics, wound protector, or redosing intravenous antibiotic prophylaxis plus chlorhexidine-alcohol intraoperative skin preparation was associated with the absence of infection (consistency = 0.94, coverage = 0.96). Four of the 5 principal component composites in various combinations were associated with the absence of surgical site infection, whereas the composite consisting of occlusive dressing placement, postoperative dressing removal, and daily postoperative chlorhexidine incisional cleansing had no association with the outcome. LIMITATIONS: The inclusion of hospitals engaged in quality improvement initiatives may limit the generalizability of these data. CONCLUSION: Bundle elements had varying association with infection reduction. Implementation of colorectal surgical site infection reduction bundles should focus on the specific elements associated with low surgical site infections.

A National Survey of Motor Vehicle Crashes Among General Surgery Residents.

OBJECTIVES: Evaluate the frequency of self-reported, post-call hazardous driving events in a national cohort of general surgery residents and determine the associations between duty hour policy violations, psychiatric well-being, and hazardous driving events. SUMMARY OF BACKGROUND DATA: MVCs are a leading cause of resident mortality. Extended work shifts and poor psychiatric well-being are risk factors for MVCs, placing general surgery residents at risk. METHODS: General surgery residents from US programs were surveyed after the 2017 American Board of Surgery In-Training Examination. Outcomes included self-reported nodding off while driving, near-miss MVCs, and MVCs. Group-adjusted cluster Chi-square and hierarchical regression models with program-level intercepts measured associations between resident- and program-level factors and outcomes. RESULTS: Among 7391 general surgery residents from 260 programs (response rate 99.3%), 34.7% reported nodding off while driving, 26.6% a near-miss MVC, and 5.0% an MVC over the preceding 6 months. More frequent 80-hour rule violations were associated with all hazardous driving events: nodding off while driving {59.8% with ≥5 months with violations vs 27.2% with 0, adjusted odds ratio (AOR) 2.86 [95% confidence interval (CI) 2.21-3.69]}, near-miss MVCs, [53.6% vs 19.2%, AOR 3.28 (95% CI 2.53-4.24)], and MVCs [14.0% vs 3.5%, AOR 2.46 (95% CI 1.65-3.67)]. Similarly, poor psychiatric well-being was associated with all 3 outcomes [eg, 8.0% with poor psychiatric well-being reported MVCs vs 2.6% without, odds ratio 2.55 (95% CI 2.00-3.24)]. CONCLUSIONS: Hazardous driving events are prevalent among general surgery residents and associated with frequent duty hour violations and poor psychiatric well-being. Greater adherence to duty hour standards and efforts to improve well-being may improve driving safety.

Children overclaim more knowledge than adults do, but for different reasons.

Overclaiming is the phenomenon whereby people claim more knowledge of a topic than they actually have. In adults, this behavior is related to the extent to which they consider themselves an expert on that topic and may be related to impression management. We investigated the emergence of this phenomenon by developing a child-friendly overclaiming questionnaire (OCQ)-the Child-OCQ. We measured the tendency of children (5-10 years of age old; N = 94) to claim knowledge of items that did not exist for a variety of topics (places, characters, animals, food, and musical instruments). We also examined the relationship between children's overclaiming of knowledge and their self-perceived liking of, and expertise in, the topics. To validate our scale, an adult sample (N = 51) completed both the Child-OCQ and a standardized adult OCQ, the OCQ-150, showing similar overclaiming patterns on both measures. Although overclaiming behaviors decreased throughout childhood, even children as old as 10 years were not adult-like and were more likely to overclaim knowledge than adults. In addition, we did not find strong evidence that children's perceived expertise on a topic influenced their tendency to overclaim knowledge, suggesting that the mechanisms behind the overclaiming phenomenon are different in children and do not reflect impression management until later during adolescence or adulthood.

Development and validation of a risk calculator for post-discharge venous thromboembolism following hepatectomy for malignancy.

BACKGROUND: Post-discharge venous thromboembolism (VTE) chemoprophylaxis decreases VTEs following cancer surgery, however identifying high-risk patients remains difficult. Our objectives were to (1) identify factors available at hospital discharge associated with post-discharge VTE following hepatectomy for malignancy and (2) develop and validate a post-discharge VTE risk calculator to evaluate patient-specific risk. METHODS: Patients who underwent hepatectomy for malignancy from 2014 to 2017 were identified from the ACS NSQIP hepatectomy procedure targeted module. Multivariable logistic regression identified factors associated with post-discharge VTE. A post-discharge VTE risk calculator was constructed, and predicted probabilities of post-discharge VTE were calculated. RESULTS: Among 11 172 patients, 95 (0.9%) developed post-discharge VTE. Post-discharge VTE was associated with obese BMI (OR 2.29 vs. normal BMI [95%CI 1.31-3.99]), right hepatectomy/trisegmentectomy (OR 1.63 vs. partial/wedge [95%CI 1.04-2.57]), and several inpatient postoperative complications: renal insufficiency (OR 5.29 [95%CI 1.99-14.07]), transfusion (OR 1.77 [95%CI 1.12-2.80]), non-operative procedural intervention (OR 2.97 [95%CI 1.81-4.86]), and post-hepatectomy liver failure (OR 2.22 [95%CI 1.21-4.08]). Post-discharge VTE risk ranged from 0.3% to 30.2%. Twenty iterations of 10-fold cross validation identified internal validity. CONCLUSIONS: Risk factors from all phases of care, including inpatient complications, are associated with post-discharge VTE following hepatectomy. Identifying high-risk patients may allow for personalized risk-based post-discharge chemoprophylaxis prescribing.

Margin Positivity in Resectable Esophageal Cancer: Are there Modifiable Risk Factors?

BACKGROUND: Patients with esophageal cancer have poor overall survival, with positive resection margins worsening survival. Margin positivity rates are used as quality measures in other malignancies, but modifiable risk factors are necessary to develop actionable targets for improvement. Our objectives were to (1) evaluate trends in esophageal cancer margin positivity, and (2) identify modifiable patient/hospital factors associated with margin positivity. METHODS: Patients who underwent esophagectomy from 2004 to 2015 were identified from the National Cancer Database. Trends in margin positivity by time and hospital volume were evaluated using Cochrane-Armitage tests. Associations between patient/hospital factors and margin positivity were assessed by multivariable logistic regression. RESULTS: Among 29,706 patients who underwent esophagectomy for cancer, 9.37% had positive margins. Margin positivity rates decreased over time (10.62% in 2004 to 8.61% in 2015; p < 0.001). Older patients (≥ 75 years) were more likely to have positive margins [odds ratio (OR) 2.04, 95% confidence interval (CI) 1.42-2.92], as were patients with a Charlson-Deyo Index ≥ 3 (OR 1.84, 95% CI 1.08-3.12). Patients who received neoadjuvant therapy were less likely to have positive margins (OR 0.37, 95% CI 0.29-0.47), while laparoscopic surgical approach was associated with increased margin positivity (OR 1.70, 95% CI 1.40-2.06). As the hospital annual esophagectomy volume increased, margin positivity rates decreased (7.76% in the fourth quartile vs. 11.39% in the first quartile; OR 0.70, 95% CI 0.49-0.99). CONCLUSIONS: Use of neoadjuvant therapy, surgical approach, and hospital volume are modifiable risk factors for margin positivity in esophageal cancer. These factors should be considered in treatment planning, and margin positivity rates could be considered as a quality measure in esophageal cancer.

Adequate Lymphadenectomy as a Quality Measure in Esophageal Cancer: Is there an Association with Treatment Approach?

BACKGROUND: The national comprehensive cancer network defines adequate lymphadenectomy as evaluation of ≥ 15 lymph nodes in esophageal cancer. However, varying thresholds have been suggested following neoadjuvant therapy. OBJECTIVES: Our objectives were to (1) explore trends in adequate lymphadenectomy rates over time; (2) evaluate unadjusted lymphadenectomy yield by treatment characteristics; and (3) identify independent factors associated with adequate lymphadenectomy. METHODS: The National Cancer Data Base was used to identify patients who underwent esophagectomy for cancer from 2004 to 2015. Adequate lymphadenectomy trends over time were evaluated using the Cochrane-Armitage test, and lymph node yield by treatment approach was compared using the Mann-Whitney U and Kruskal-Wallis tests. Associations with treatment factors were assessed by multivariable logistic regression. RESULTS: Among 24,413 patients, 9919 (40.6%) had adequate lymphadenectomy. Meeting the nodal threshold increased over time (52.6% in 2015 vs. 26.0% in 2004; p < 0.01). Lymph node yield did not differ based on neoadjuvant therapy (median 12 [interquartile range 7-19] with and without neoadjuvant therapy; p = 0.44). Adequate lymphadenectomy was not associated with neoadjuvant therapy (40.5% vs. 40.8%, odds ratio [OR] 0.94, 95% confidence interval [CI] 0.82-1.07), but was associated with surgical approach (52.7% of laparoscopic cases, OR 1.28, 95% CI 1.06-1.56; 61.2% of robotic cases, OR 1.71, 95% CI 1.34-2.19, vs. 43.5% of open cases), and increasing annual esophagectomy volume (55.6% in the fourth quartile vs. 32.6% in the first quartile; OR 3.57, 95% CI 2.35-5.43). CONCLUSIONS: Despite increases over time, only 50% of patients undergo adequate lymphadenectomy during esophageal cancer resection. Adequate lymphadenectomy was not associated with neoadjuvant therapy. Focusing on surgical approach and esophagectomy volume may further improve adequate lymphadenectomy rates.

National Use of Chemotherapy in Initial Management of Stage I Pancreatic Cancer and Failure to Perform Subsequent Resection.

INTRODUCTION: Chemotherapy is increasingly administered prior to resection in patients with early-stage pancreatic adenocarcinoma, but the national prevalence of this practice is poorly understood. Our objectives were to (1) describe the utilization of upfront chemotherapy management of stage I pancreatic cancer; (2) define factors associated with the use of upfront chemotherapy and subsequent resection; and (3) assess hospital-level variability in upfront chemotherapy and subsequent resection. METHODS: The National Cancer Database was used to identify patients treated for clinical stage I pancreatic adenocarcinoma. Outcomes were receipt of upfront chemotherapy and surgical resection after upfront chemotherapy. Associations between patient/hospital factors and both initial management and subsequent resection were assessed by multivariable logistic regression. RESULTS: A total of 17,495 patients were included, with 26.6% receiving upfront chemotherapy. Upfront chemotherapy was more likely in patients who were ≥ 80 years of age (odds ratio [OR] 1.64, 95% confidence interval [CI] 1.39-1.93), had T2 tumors (OR 2.56, 95% CI 2.36-2.78), or were treated at a low-volume center (OR 2.10, 95% CI 1.63-2.71). Among patients receiving upfront chemotherapy, only 33.5% underwent subsequent resection. Resection was more likely in patients with T1 tumors (OR 1.22, 95% CI 1.04-1.43) and in those treated at high-volume centers (OR 4.03, 95% CI 2.90-5.60). Only 20.4% of hospitals performed resection in > 50% of patients after upfront chemotherapy. CONCLUSION: Rates of surgical resection after upfront chemotherapy are relatively low, and the proportion of patients who eventually undergo resection varies considerably between hospitals. The use of surgery after upfront chemotherapy in resectable pancreatic cancer should be considered as an internal quality-of-cancer-care measure.

Utilization and Treatment Patterns of Cytoreduction Surgery and Intraperitoneal Chemotherapy in the United States.

INTRODUCTION: Cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) is an effective treatment option for selected patients with peritoneal metastases (PM), but national utilization patterns are poorly understood. The objectives of this study were to (1) describe population-based trends in national utilization of CRS/IPC; (2) define the most common indications for the procedure; and (3) characterize the types of hospitals performing the procedure. METHODS: The National Inpatient Sample (NIS) was used to identify patients from 2006 to 2015 who underwent CRS/IPC, and to calculate national estimates of procedural frequency and oncologic indication. Hospitals performing CRS/IPC were classified based on size and teaching status. RESULTS: The estimated annual number of CRS/IPC cases increased significantly from 189 to 1540 (p < 0.001). Overall, appendiceal cancer was the most common indication (25.7%), followed by ovarian cancer (23.3%), colorectal cancer (22.5%), and unspecified PM (15.0%). Remaining cases (13.5%) were performed for other indications. Most cases were performed in large teaching hospitals (65.9%), compared with smaller teaching hospitals (25.1%), large non-teaching hospitals (5.3%), or small non-teaching hospitals (3.2%). Patients were more likely to undergo CRS/IPC without a diagnosis based on level I evidence (appendiceal, ovarian, or colorectal) at large non-academic hospitals (odds ratio 2.00, 95% confidence interval 1.18-3.38, p = 0.010) compared with large academic hospitals. CONCLUSIONS: Utilization of CRS/IPC is increasing steadily in the US, is performed at many types of facilities, and often for a variety of indications that are not supported by high-level evidence. Given associated morbidity of CRS/IPC, a national registry dedicated to cases of IPC is necessary to further evaluate use and outcomes.

Post-discharge venous thromboembolism after pancreatectomy for malignancy: Predicting risk based on preoperative, intraoperative, and postoperative factors.

BACKGROUND AND OBJECTIVES: Extended chemoprophylaxis is recommended for high-risk patients following pancreatectomy for malignancy. However, quantifying risk remains difficult. We sought to (a) identify factors associated with post-discharge venous thromboembolism (VTE) following pancreatectomy for malignancy and (b) develop a post-discharge VTE risk calculator to identify high-risk patients. METHODS: Patients who underwent pancreatectomy for malignant histology from 2014 to 2018 were identified from the ACS NSQIP pancreatectomy procedure targeted dataset. Preoperative, intraoperative, and postoperative factors known at hospital discharge were evaluated for association with post-discharge VTE via multivariable logistic regression. A post-discharge VTE risk calculator was developed and validated. RESULTS: Of 19 340 analyzed patients, 280 (1.5%) developed post-discharge VTE. Post-discharge VTE was associated with increasing body mass index (BMI; eg, morbidly obese BMI odds ratio [OR]: 1.99 [95% confidence interval {CI}: 1.30-3.02] vs normal BMI), procedure type (distal pancreatectomy OR: 1.47 [95% CI: 1.02-2.12] vs pancreaticoduodenectomy), pancreatic fistula (OR: 1.59 [95% CI: 1.19-2.13]) and delayed gastric emptying (OR: 1.81 [95% CI: 1.29-2.52]). Patients' predicted probability of post-discharge VTE ranged from 0.7% to 9.0%. Twenty iterations of 10-fold cross-validation demonstrated internal validity. CONCLUSIONS: Preoperative, intraoperative, and postoperative factors were associated with post-discharge VTE following pancreatectomy for malignancy. This post-discharge VTE risk calculator allows for quantification of individual post-discharge VTE risk, which ranged from 0.7% to 9.0%.

Timing of palliative care: When to call for a palliative care consult.

Palliative care, unlike hospice, can be utilized concurrently with disease-modifying or curative therapies. Some of the benefits of palliative care include improved quality of life, less end-of-life treatment, and decreased medical costs. Furthermore, palliative care can help guide treatment decisions to be in line with patients' physical, psychological, and spiritual needs. On the basis of these benefits, we advocate for palliative care involvement early in the course of advanced malignancy and other terminal diagnoses.

Nonresectional regional therapies for metastatic colorectal cancer to the liver.

The liver is the second leading site of colorectal cancer metastases, following the lymph nodes. Although metastatic resection for colorectal cancer liver metastases has been shown to improve survival, many patients cannot undergo surgery. Several nonsurgical therapies are available in these situations, however high-quality evidence comparing the effectiveness of these therapies is sparse. Here, we review the currently available evidence in support of nonresectional regional therapies for colorectal metastases to the liver.

Effect of Restriction of the Number of Concurrently Open Records in an Electronic Health Record on Wrong-Patient Order Errors: A Randomized Clinical Trial.

Importance: Recommendations in the United States suggest limiting the number of patient records displayed in an electronic health record (EHR) to 1 at a time, although little evidence supports this recommendation. Objective: To assess the risk of wrong-patient orders in an EHR configuration limiting clinicians to 1 record vs allowing up to 4 records opened concurrently. Design, Setting, and Participants: This randomized clinical trial included 3356 clinicians at a large health system in New York and was conducted from October 2015 to April 2017 in emergency department, inpatient, and outpatient settings. Interventions: Clinicians were randomly assigned in a 1:1 ratio to an EHR configuration limiting to 1 patient record open at a time (restricted; n = 1669) or allowing up to 4 records open concurrently (unrestricted; n = 1687). Main Outcomes and Measures: The unit of analysis was the order session, a series of orders placed by a clinician for a single patient. The primary outcome was order sessions that included 1 or more wrong-patient orders identified by the Wrong-Patient Retract-and-Reorder measure (an electronic query that identifies orders placed for a patient, retracted, and then reordered shortly thereafter by the same clinician for a different patient). Results: Among the 3356 clinicians who were randomized (mean [SD] age, 43.1 [12.5] years; mean [SD] experience at study site, 6.5 [6.0] years; 1894 females [56.4%]), all provided order data and were included in the analysis. The study included 12 140 298 orders, in 4 486 631 order sessions, placed for 543 490 patients. There was no significant difference in wrong-patient order sessions per 100 000 in the restricted vs unrestricted group, respectively, overall (90.7 vs 88.0; odds ratio [OR], 1.03 [95% CI, 0.90-1.20]; P = .60) or in any setting (ED: 157.8 vs 161.3, OR, 1.00 [95% CI, 0.83-1.20], P = .96; inpatient: 185.6 vs 185.1, OR, 0.99 [95% CI, 0.89-1.11]; P = .86; or outpatient: 7.9 vs 8.2, OR, 0.94 [95% CI, 0.70-1.28], P = .71). The effect did not differ among settings (P for interaction = .99). In the unrestricted group overall, 66.2% of the order sessions were completed with 1 record open, including 34.5% of ED, 53.7% of inpatient, and 83.4% of outpatient order sessions. Conclusions and Relevance: A strategy that limited clinicians to 1 EHR patient record open compared with a strategy that allowed up to 4 records open concurrently did not reduce the proportion of wrong-patient order errors. However, clinicians in the unrestricted group placed most orders with a single record open, limiting the power of the study to determine whether reducing the number of records open when placing orders reduces the risk of wrong-patient order errors.

Making the Most of Five Minutes: The Clinical Teaching Moment.

Clinical educators face the challenge of simultaneously caring for patients and teaching learners, often with an unpredictable caseload and learners of varied abilities. They also often have little control over the organization of their time. Effective clinical teaching must encourage student participation, problem solving, integration of basic and clinical knowledge, and deliberate practice. Close supervision and timely feedback are also essential. Just as one develops an effective lecture through training and practice, clinical teaching effectiveness may also be improved by using specific skills to teach in small increments. The purpose of this paper is to identify potential teachable moments and to describe efficient instructional methods to use in the clinical setting under time constraints. These techniques include asking better questions, performing focused observations, thinking aloud, and modeling reflection. Different frameworks for teaching encounters during case presentations can be selected according to learner ability and available time. These methods include modeling and deconstructing the concrete experience; guiding the thinking and reflecting process; and providing the setting and opportunity for active practice. Use of these educational strategies encourages the learner to acquire knowledge, clinical reasoning, and technical skills, and also values, attitudes, and professional judgment.
