Preoperative Risk Factors for Discharge to Facility After Surgery in Geriatric Patients. Am Surg 2024:31348241256056. [PMID: 38788760 DOI: 10.1177/00031348241256056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/26/2024]
Abstract
BACKGROUND The Geriatric Surgery Verification Program (GSV) was developed to address perioperative care for patients ≥75 years, with a goal of improving outcomes and functional abilities after surgery. We sought to evaluate preoperative factors that place patients at risk for inability to return home (ie, discharge to a facility). METHODS Retrospective review of patients ≥75 years old who underwent inpatient surgery from January 2018 to December 2022 at a referral Veterans Administration Medical Center enrolled in the GSV program. Preoperative factors included fall history, mobility aids, housing status, function, cognition, and nutritional status. Postoperative outcomes were discharge designations as home and home with services compared to a facility (skilled nursing facility and acute rehab). Exclusion criteria included preoperative facility residence, cardiac surgery, hospital transfer, postoperative complications, hospice discharge, or in-hospital mortality. RESULTS 605 patients met inclusion criteria and 173 (29%) excluded as above. Of the remaining 432 patients, mean age was 79 ± 5 and the majority were male, 426 (99%). The majority of patients were discharged home, 388 (90%), compared to a facility, 44 (10%). Patients with a fall history (OR: 2.95, 95% CI: 1.56, 5.57), utilizing a mobility aid (OR: 6.0, 95% CI: 2.8, 12.83), were partial or totally dependent (OR: 4.83, 95% CI: 2.29, 10.17), or who lived alone (OR: 2.57, 95% CI: 1.08, 6.07) had higher rates of discharge to a facility. DISCUSSION Preoperative mobility compromise and functional dependence are associated with higher rates of discharge to a facility. These preoperative factors are possibly modifiable with multidisciplinary care teams to decrease risks of facility placement.

Telehealth for general surgery postoperative care. Am J Surg 2024; 229:156-161. [PMID: 38158263 DOI: 10.1016/j.amjsurg.2023.12.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 12/14/2023] [Accepted: 12/21/2023] [Indexed: 01/03/2024]
Abstract
BACKGROUND Telehealth utilization rapidly increased following the pandemic. However, it is not widely used in the Veteran surgical population. We sought to evaluate postoperative telehealth in patients undergoing general surgery. METHODS Retrospective review of Veterans undergoing general surgery at a level 1A VA Medical Center from June 2019 to September 2021. Exclusions were concomitant procedure(s), discharge with drains or non-absorbable sutures/staples, complication prior to discharge or pathology positive for malignancy. RESULTS 1075 patients underwent qualifying procedures, 124 (12 %) were excluded and 162 (17 %) did not have follow-up. 443 (56 %) patients followed-up in-person (56 %) vs 346 (44 %) via telehealth. Telehealth patients had a lower rate of complications, 6 % vs 12 %, p = 0.013. There were no significant differences in ED visits, 30-day readmission, postoperative procedures or missed adverse events. CONCLUSION Telehealth follow-up after general surgical procedures is safe and effective. Postoperative telehealth care should be considered after low-risk general surgery procedures.

Outpatient surgery postoperative ambulation and emergency department utilization. Surg Endosc 2024; 38:999-1004. [PMID: 38017159 DOI: 10.1007/s00464-023-10575-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Accepted: 10/19/2023] [Indexed: 11/30/2023]
Abstract
BACKGROUND The ability to ambulate is an important indicator for wellness and quality of life. A major health event, such as a surgery, can derail this ability, and return to preoperative walking ability is a marker for recovery. Self-reported walking measurements by patients are subject to bias, thus wearable technology such as activity monitors have risen in popularity. We evaluated postoperative ambulation using an accelerometer in outpatient general surgery procedures with the hypothesis that those patients with less postoperative ambulation were at risk for adverse outcomes. METHODS A retrospective review of patients undergoing outpatient abdominal surgeries from November 2016 to July 2019 at a Veteran Affairs Medical Center. Patients wore an accelerometer preoperatively and postoperatively to measure their ambulation (steps/day). Outcome measures were 30-day readmissions and Emergency Department (ED) utilization. Postoperative ambulation was defined as daily percentages of their preoperative baseline. Patients without preoperative baseline data, > 3 missing days or any missing days prior to reaching baseline were excluded. RESULTS One-hundred-six patients underwent outpatient abdominal surgery. Twenty-two patients were excluded. Patients stratified into adult (18-64 years, 44 patients, 52%) and geriatric (≥ 65 years, 40 patients, 48%) cohorts. Geriatric patients were less likely to meet their preoperative baseline by postoperative day 7, 35% vs 61%, p = 0.016. Adult patients who failed to meet their preoperative baseline in first postoperative week had higher ED utilization; 4 (24%) vs 1 (4%), p = 0.04. Geriatric patients who failed to meet their baseline trended toward increased ED utilization; 5 (19%) vs. 1 (7%), p = 0.31. CONCLUSION Patients aged < 65 who fail to return to their preoperative daily step count within one week of outpatient abdominal surgery are 6× more likely to be seen in the ED. Postoperative ambulation may be able to predict ED utilization and recovery after outpatient surgery.

Clin-STAR corner: Practice-changing advances at the interface of surgery and geriatrics. J Am Geriatr Soc 2024. [PMID: 38280226 DOI: 10.1111/jgs.18783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 12/24/2023] [Indexed: 01/29/2024]
Abstract
Older adults who undergo major operations are at high risk for complications, disability, and death. The physio-social compromises unique to older adults are not routinely assessed and managed in the perioperative setting. Currently, the most practice-changing topic nationally in geriatric surgery is the implementation of comprehensive, multidisciplinary geriatric care pathways to provide age-friendly care for older adults throughout their perioperative course. This review presents three recently published articles focused on defining evidence-based outcomes associated with implementation of a comprehensive geriatric surgery program for older adults undergoing major inpatient operations. These studies serve as the initial evidence evaluating the efficacy and effectiveness of comprehensive perioperative geriatric surgery programs. Each study was chosen due to their high potential for meaningful impact for both clinicians and healthcare systems looking to improve their surgical care of older adults.

Changes in leukocyte telomere length among children with obesity participating in a behavioural weight control program. Pediatr Obes 2023; 18:e13082. [PMID: 37873898 PMCID: PMC10843039 DOI: 10.1111/ijpo.13082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 09/25/2023] [Accepted: 09/28/2023] [Indexed: 10/25/2023]
Abstract
OBJECTIVE To examine changes in leukocyte telomere length (LTL) during and after a behavioural weight control program for children with obesity. METHODS We measured LTL among a cohort of 158 children 8-12 years of age with a body mass index greater than or equal to the 95th percentile for age and sex. Children were 55% female, 29% white, 52% Latinx, 8% Asian and 11% Pacific Islander, other or multiethnic. All children participated in a 6-month, family-based, group behavioural weight control program and were assessed before treatment, after treatment and 1 year after the end of treatment. To test the sample population slope of LTL over the intervention and maintenance time periods, we fit spline mixed-effect regression models. RESULTS LTL increased an average of 0.09 T/S units per year (95% confidence interval [CI] 0.04 to 0.13; p = 0.0001) during the weight control program intervention period, followed by an average decline of -0.05 T/S units per year (95% CI -0.08 to -0.03; p < 0.0001) during the 1 year of follow-up after the completion of the intervention. Among 26 social, psychological, behavioural and physiological factors we examined, we did not find any predictors of these changes. CONCLUSIONS LTL increased in response to a behavioural weight control program among children with obesity, suggesting an impact on biological health and cellular aging from participation in a behavioural weight control intervention. LTL may be a useful biomarker for assessing changes in response to behavioural interventions.

Abstract
The sequencing of information in media can influence processing of content via mechanisms like framing, mood management, and emotion regulation. This study examined three kinds of media sequences on smartphones: (1) balancing positive and negative emotional content; (2) balancing emotional content with informational content; and (3) balancing time spent on and off the media device. Actual media use was measured in natural settings using the Screenomics framework which gathers screenshots from smartphones every 5 s when devices are on. Time-series analyses of 223,531 smartphone sessions recorded from 94 participants showed that emotionally positive content was more likely to follow negative content, and that emotionally negative content was more likely to follow positive content; emotional content was more likely to follow informational content, and informational content was more likely to follow emotional content; and longer smartphone sessions were more likely to follow longer periods of non-use.

Simple dietary substitutions can reduce carbon footprints and improve dietary quality across diverse segments of the US population. NATURE FOOD 2023; 4:966-977. [PMID: 37884673 PMCID: PMC10725296 DOI: 10.1038/s43016-023-00864-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Accepted: 09/19/2023] [Indexed: 10/28/2023]
Abstract
Changing what foods we eat could reduce environmental harms and improve human health, but sweeping dietary change is challenging. We used dietary intake data from a nationally representative sample of 7,753 US children and adults to identify simple, actionable dietary substitutions from higher- to lower-carbon foods (for example, substituting chicken for beef in mixed dishes such as burritos, but making no other changes to the diet). We simulated the potential impact of these substitutions on dietary carbon emissions and dietary quality. If all consumers who ate the high-carbon foods instead consumed a lower-carbon substitute, the total dietary carbon footprint in the United States would be reduced by more than 35%. Moreover, if adopted, these substitutions would improve consumers' overall dietary quality by 4-10%, with benefits projected for all age, gender, and racial and ethnic groups. These results suggest that a 'small changes' approach could be a valuable starting point for addressing diet's impact on climate and health.

Abstract
BACKGROUND Stray energy transfer from monopolar instruments during laparoscopic surgery is a recognized cause of potentially catastrophic complications. There are limited data on stray energy injuries in robotic surgery. We sought to characterize stray energy injury in the form of superficial burns to the skin surrounding laparoscopic and robotic trocar sites. Our hypothesis was that stray energy burns will occur at all laparoscopic and robotic port sites. METHODS We conducted a prospective, randomized controlled trial of patients undergoing elective unilateral inguinal hernia repair at a VAMC over a 4-year period. Surgery was performed via transabdominal preperitoneal approach either laparoscopic-assisted (TAPP) or robotic-assisted (rTAPP). A monopolar scissor was used to deliver energy at 30W coagulation for all cases. At completion of the procedure, skin biopsies were taken from all the port sites. A picro-Sirius red stain was utilized to identify thermal injury by a blinded pathologist. RESULTS Over half (54%, 59/108) of all samples demonstrated thermal injury to the skin. In the laparoscopic group, 49% (25/51) samples showed thermal injury vs. 60% (34/57) in the robotic group (p = 0.548). The camera port was the most frequently involved with 68% (13/19) rTAPP samples showing injury vs. 47% (8/17) in the TAPP group (p = 0.503). There was no difference in the rate of injury at the working port site (rTAPP 53%, 10/19 vs. TAPP 47%, 8/17; p = 0.991) or the assistant port site (rTAPP 58%, 11/19 vs. TAPP 53%, 9/17; p = 0.873). CONCLUSIONS Stray energy causes thermal injury to the skin at port sites in the majority robotic laparoscopic TAPP inguinal hernia repairs. There is no difference in stray energy transfer between the laparoscopic and robotic platform. This is the first study to confirm in-vivo transfer of stray energy during robotic surgical procedures. More study is needed to determine the clinical significance of these thermal injuries.

Abstract
Up to now, there was no way to observe and track the affective impacts of the massive amount of complex visual stimuli that people encounter "in the wild" during their many hours of digital life. In this paper, we propose and illustrate how recent advances in AI-trained ensembles of deep neural networks-can be deployed on new data streams that are long sequences of screenshots of study participants' smartphones obtained unobtrusively during everyday life. We obtained affective valence and arousal ratings of hundreds of images drawn from existing picture repositories often used in psychological studies, and a new screenshot repository chronicling individuals' everyday digital life from both N = 832 adults and an affect computation model (Parry & Vuong, 2021). Results and analysis suggest that (a) our sample rates images similarly to other samples used in psychological studies, (b) the affect computation model is able to assign valence and arousal ratings similarly to humans, and (c) the resulting computational pipeline can be deployed at scale to obtain detailed maps of the affective space individuals travel through on their smartphones. Leveraging innovative methods for tracking the emotional content individuals encounter on their smartphones, we open the possibility for large-scale studies of how the affective dynamics of everyday digital life shape individuals' moment-to-moment experiences and well-being.

Abstract
BACKGROUND The American College of Surgeons (ACS) Coalition for Quality in Geriatric Surgery (CQGS) identified standards of surgical care for the growing, vulnerable population of aging adults in the US. The aims of this study were to determine implementation feasibility for 30 selected standards, identify barriers and best practices in their implementation, and further refine these geriatric standards and verification process. STUDY DESIGN The CQGS requested participation from hospitals involved in the ACS NSQIP Geriatric Surgery Pilot Project, previous CQGS feasibility analyses, and hospitals affiliated with a core development team member. Thirty standards were selected for implementation. After implementation, site visits were conducted, and postvisit surveys were distributed. RESULTS Eight hospitals were chosen to participate. Program management (55%), immediate preoperative and intraoperative clinical care (62.5%), and postoperative clinical care (58%) had the highest mean percentage of "fully compliant" standards. Goals and decision-making (30%), preoperative optimization (28%), and transitions of care (12.5%) had the lowest mean percentage of fully compliant standards. Best practices and barriers to implementation were identified across 13 of the 30 standards. More than 80% of the institutions reported that participation changed the surgical care provided for older adults. CONCLUSIONS This study represents the first national implementation assessment undertaken by the ACS for one of its quality programs. The CQGS pilot testing was able to demonstrate implementation feasibility for 30 standards, identify challenges and best practices, and further inform dissemination of the ACS Geriatric Surgery Verification Program.

Abstract
Advances in ability to comprehensively record individuals' digital lives and in AI modeling of those data facilitate new possibilities for describing, predicting, and generating a wide variety of behavioral processes. In this paper, we consider these advances from a person-specific perspective, including whether the pervasive concerns about generalizability of results might be productively reframed with respect to transferability of models, and how self-supervision and new deep neural network architectures that facilitate transfer learning can be applied in a person-specific way to the super-intensive longitudinal data arriving in the Human Screenome Project. In developing the possibilities, we suggest Molenaar add a statement to the person-specific Manifesto - "In short, the concerns about generalizability commonly leveled at the person-specific paradigm are unfounded and can be fully and completely replaced with discussion and demonstrations of transferability."

Abstract
Although media production is a critical concept in communication theory, we know surprisingly little about the timing, content, and context of individuals' production behavior. Intensive observation and analysis of 94 American adults' smartphone use over 1 week showed that although time spent in producing content was on average only about 6 percent of the amount of time spent on smartphones, the production content was more purposeful, expressive, articulate, condensed, confident, personal, and emotionally charged than consumption content. Analysis of the temporal dynamics of production suggests that the content consumed in the minute before individuals' production began to resemble the subsequently produced content. Other results suggest that content production on smartphones was fragmented, idiosyncratic, and purposeful, highlighting the impact of individuals' quick interactions with media, and the need to develop user-centric theories about how, when, and why individuals produce digital content.

Abstract
INTRODUCTION Telehealth has been increasingly utilized with a renewed interest by surgical specialties given the COIVD-19 pandemic. Limited data exists evaluating the safety of routine postoperative telehealth follow-up in patients undergoing inguinal hernia repair, especially those who present urgent/emergently. Our study sought to evaluate the safety and efficacy of postoperative telehealth follow-up in veterans undergoing inguinal hernia repair. METHODS Retrospective review of all Veterans who underwent inguinal hernia repair at a tertiary Veterans Affairs Medical Center over a 2-year period (9/2019-9/2021). Outcome measures included postoperative complications, emergency department (ED) utilization, 30-day readmission, and missed adverse events (ED utilization or readmission occurring after routine postoperative follow-up). Patients undergoing additional procedure(s) requiring intraoperative drains and/or nonabsorbable sutures were excluded. RESULTS Of 338 patients who underwent qualifying procedures, 156 (50.6%) were followed-up by telehealth and 152 (49.4%) followed-up in-person. There were no differences in age, sex, BMI, race, urgency, laterality nor admission status. Patients with higher American Society of Anesthesiologists (ASA) classification [ASA class III 92 (60.5%) versus class II 48 (31.6%), P = 0.019] and open repair [93 (61.2%) versus 67 (42.9%), P = 0.003] were more likely to follow-up in-person. There was no difference in complications, [telehealth 13 (8.3%) versus 20 (13.2%), P = 0.17], ED visits, [telehealth 15 (10%) versus 18 (12%), P = 0.53], 30-day readmission [telehealth 3 (2%) versus 0 (0%), P = 0.09], nor missed adverse events [telehealth 6 (33.3%) versus 5 (27.8%), P = 0.72]. CONCLUSIONS There were no differences in postoperative complications, ED utilization, 30-day readmission, or missed adverse events for those who followed-up in person versus telehealth after elective or urgent/emergent inguinal hernia repair. Veterans with a higher ASA class and who underwent open repair were more likely to be seen in person. Telehealth follow-up after inguinal hernia repair is safe and effective.

Abstract
This prospective, longitudinal study examined associations between whether and when children first acquire a mobile phone and their adjustment measures, among low-income Latinx children. Children (N = 263; 55% female; baseline Mage = 9.5) and their parents were assessed annually for 5 years from 2012. Children first acquired a mobile phone at a mean (SD) age of 11.62 (1.41) years. Pre-registered multilevel models tested associations linking phone ownership, phone acquisition age, and the interaction between ownership and acquisition age to levels and changing trends of depressive symptoms, school grades, and reported and objectively assessed sleep. Results showed no statistically significant associations, controlling the False Discovery Rate. Findings suggest an absence of meaningful links from mobile phone ownership and acquisition age to child adjustment.

Abstract
INTRODUCTION Stray energy from surgical energy instruments can cause unintended thermal injuries. There are no published data regarding electrosurgical generators and their influence on stray energy transfer during robotic surgery. There are two approved generators for the DaVinci Xi robotic platform: a constant-voltage regulating generator (cVRG) and a constant-power regulating generator (cPRG). The purpose of this study was to quantify and compare stray energy transfer in the robotic Xi platform using a cVRG versus a cPRG. METHODS An ex vivo bovine model was used to simulate a standard multiport robotic surgery. The DaVinci Xi (Intuitive Surgical, Sunnyvale, CA) robotic platform was attached to a trainer box using robotic ports. A 5 s, open-air activation of the monopolar scissors was done with commonly used electrosurgical settings using a cPRG (ForceTriad, Covidien-Medtronic, Boulder, CO) or cVRG (ERBE VIO 300 dV 2.0, ERBE USA, Marietta, GA). Stray energy transfer was quantified as the change in tissue temperature (°C) nearest the tip of the assistance grasper (which was not in direct contact with the active monopolar scissors). RESULTS Stray energy transfer occurred with both generators. Utilizing common, comparable settings for standard coagulation, significantly less stray energy was transferred with the cVRG versus cPRG (4.4 ± 1.6 °C vs. 41.1 ± 13.0 °C, p < 0.001). Similarly, less stray energy was transferred using cut modes with the cVRG compared to the cPRG (5.61 ± 1.79 °C vs. 33.9 ± 18.4 °C, p < 0.001). CONCLUSION Stray energy transfer increases tissue temperatures more than 45C in the DaVinci Xi robotic platform. Low voltage modalities, such as cut or blend; as well as a cVRG generator, significantly reduces stray energy. Robotic surgeons can minimize the risk of stray energy injuries by using these low risk modes and/or generator.

BACKGROUND The Fundamental Use of Surgical Energy (FUSE) program was developed by The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) to promote the safe use of surgical energy. A curriculum that could be used in hospital educational programs was needed to expand access. The goal of this project was to develop a short, inexpensive, online module that emphasizes key FUSE learning objectives. The accompanying survey assessed perceived relevancy. METHODS The SAGES FUSE Committee developed the Hospital Compliance Module. The target audience included all OR personnel. The Module was piloted at Beth Israel Deaconess Medical Center. The data were analyzed using Chi-square with Yates' correction two-tailed test. RESULTS Three-hundred-eighty individuals completed the survey: 198 (52%) surgeons, 139 (37%) nurses, 28 (7%) surgical technicians, and 15 (4%) house staff. For "…the Module taught me valuable information" 155 (41%) responded extremely and 350 (92%) responded at least somewhat. For "As a result of [the Module] how likely are you to change how you set up or use energy devices…?" 103 (27%) responded extremely and 305 (80%) responded at least somewhat. For "How likely are you to recommend this compliance module…?" 143 (38%) responded extremely and 333 (88%) responded at least somewhat. CONCLUSION The FUSE Hospital Compliance Module is effective and efficient. It should be considered for widespread distribution by hospitals to enhance staff education.

A dedicated feeding tube clinic reduces emergency department utilization for gastrostomy tube complications. Surg Endosc 2022; 36:6969-6974. [PMID: 35132448 DOI: 10.1007/s00464-022-09065-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Accepted: 01/17/2022] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Enteral access is required for a variety of reasons from neuromuscular disorders to dysphagia. Gastrostomy tubes (GTs) can be placed endoscopically, surgically, or radiographically and complications include infection, bleeding, leakage and unintentional removal. Routine post-procedural follow-up is limited by inconsistent guidelines and management by different specialty teams. We established a dedicated GT clinic to provide continuity of care and prophylactic GT exchange. We hypothesized that patients followed in the GT clinic would have reduced Emergency Department (ED) utilization. METHODS A retrospective review of patients who underwent GT placement from January 2010 to January 2020 was conducted. Baseline demographics, indications for GT placement, number and reason for ED visits and utilization of a multidisciplinary GT clinic were studied. RESULTS A total of 97 patients were included. The most common indication for placement was dysphagia (88, 91%) and the most common primary diagnosis was head and neck malignancy (51, 51%). The GT clinic is a multidisciplinary clinic staffed by surgeons and residents, dieticians, and wound care specialists and cared for 16 patients in this study. Three patients (19%) in the GT clinic group required ED visits compared to 44 (54%) in the standard of care (SOC) group (p < 0.05). There was an average of 0.9 ED visits per patient (range 0-7) in the GT clinic group vs 1.6 ED visits per patient (range 0-20) in the SOC group (p = 0.34). Feeding tubes were prophylactically exchanged an average of 7 times per patient in the GT clinic group vs 3 times per patient in the SOC group (p < 0.05). CONCLUSION A multidisciplinary clinic dedicated to GT care limits ED visits for associated complications by more than 50%. Follow-up in a dedicated clinic with prophylactic tube exchange decreases ED visits and should be considered at facilities that care for patients with GTs.

Abstract
Several societal issues could be mitigated by reducing global consumption of meat and animal products (MAP). In three randomized, controlled experiments (n=217 to 574), we evaluated the effects of a documentary that presents health, environmental, and animal welfare motivations for reducing MAP consumption. Study 1 assessed the documentary's effectiveness at reducing reported MAP consumption after 12 days. This study used methodological innovations to minimize social desirability bias, a widespread limitation of past research. Study 2 investigated discrepancies between the results of Study 1 and those of previous studies by further examining the role of social desirability bias. Study 3 assessed the documentary's effectiveness in a new population anticipated to be more responsive and upon enhancing the intervention content. We found that the documentary did not decrease reported MAP consumption when potential social desirability bias was minimized (Studies 1 and 3). The documentary also did not affect consumption among participants whose demographics suggested they might be more receptive (Study 3). However, the documentary did substantially increase intentions to reduce consumption, consistent with past studies (Studies 2 and 3). Overall, we conclude that some past studies of similar interventions may have overestimated effects due to methodological biases. Novel intervention strategies to reduce MAP consumption may be needed.

Abstract
Background: Surgeons must evaluate and communicate the risk associated with operative procedures for patients at high risk of poor postoperative outcomes. Multidisciplinary approaches to complex decision making are needed. Objective: To improve physician decision making for high-risk surgical patients. Design: This is a retrospective review of patients presented to a multidisciplinary committee for three years. Setting/Subjects: Evaluation of patients was done in a single-center U.S. veterans affairs (VA) hospital. All patients who were considered for surgery had a VA Surgical Quality Improvement Program (VASQIP) risk calculator 30-day mortality >5%. Measurements: Thirty-day and one-year mortality were measured. Results: Seventy-six patients were reviewed with an average expected 30-day mortality of 14.2%. Forty-two patients (57%) had a recommended change in the care plan before surgery. Fifty-four patients (71%) proceeded with surgery and experienced a 30-day mortality of 7.4%. Conclusions and Relevance: Multidisciplinary discussion of high-risk surgical patients may help surgeons make perioperative recommendations for patients. Implementation of a multidisciplinary high-risk committee should be considered at facilities that manage high-risk surgical patients.

Abstract
BACKGROUND Recovery of preoperative ambulation levels 1 month after surgery represents an important patient-centered outcome. The objective of this study is to identify clinical factors associated with the inability to regain baseline preoperative ambulation levels 28 days postoperatively. METHODS This is a prospective cohort study enrolling patients scheduled for elective inpatient abdominal operations. Daily ambulation (steps/day) was measured with a wristband accelerometer. Preoperative steps were recorded for at least 3 full calendar days before surgery. Postoperatively, daily steps were recorded for at least 28 days. The primary outcome was delayed recovery of ambulation, defined as inability to achieve 50% of preoperative baseline steps at 28 days postoperatively. RESULTS A total of 108 patients were included. Delayed recovery (< 50% of baseline preoperative steps/day) occurred in 32 (30%) patients. Clinical factors associated with delayed recovery after multivariable logistic regression included longer operative time (OR 1.37, 95% CI 1.05-1.79), open operative approach (OR 4.87, 95% CI 1.64-14.48) and percent recovery on POD3 (OR 0.73, 95% CI 0.56-0.96). In addition, patients with delayed ambulation recovery had increased rates of postoperative complications (16% vs 1%, p < 0.01) and readmission (28% vs 5%, p < 0.01). CONCLUSION After elective inpatient abdominal operations, nearly one in three patients do not recover 50% of their baseline preoperative steps 28 days postoperatively. Factors that can be used to identify these patients include longer operations, open operations and low ambulation levels on postoperative day #3. These data can be used to target rehabilitation efforts aimed at patients at greatest risk for poor ambulatory recovery.

Abstract
Different frameworks and models exist for translating and disseminating public health policies, programs, and services. This article describes an approach, grounded in the Integrate, DEsign, Assess, and Share (IDEAS) framework for digital health innovation and the Stanford Byers Center biodesign innovation process, to design a way to make effective behavioral weight control more scalable and cost-effective for low-income children with overweight and obesity, to reduce obesity and associated morbidities. The process considered the relevant stakeholders, the current market landscape, and the potential market. Solutions were designed to address provider training and resources, to have a strong foundation in behavior change methods, be sufficiently intense to produce change, involve both children and caregivers and be delivered in groups, to be less costly to deliver than current family-based behavioral programs, and to have a viable revenue model. An iterative process resulted in a potential solution that combines both technology and human affordances and addresses high fidelity delivery, needs of providers and patients, training and support, likely customers, potential revenue models, intellectual property, and regulatory issues.

Abstract
Efficacious treatments for children with obesity have not been broadly disseminated. The Stanford Pediatric Weight Control Program (SPWCP) is grounded in behavioral theory and prior observations, follows a proven treatment model, and is consistent with the US Preventive Services Task Force (USPSTF) recommendations. It has shown high levels of participation and retention and reductions in BMI and percent of median BMI for age and sex comparable to many studied programs, as well as improvements in physiological risk factors, psychological measures, and diet, activity, and screen time behaviors in children with obesity when delivered as a real-world clinical program with sociodemographically diverse families in multiple clinic and community settings. The Stanford CORD 3.0 Project proposes to use technology, design, behavioral theory, and biomedical business innovation strategies to package and scale the SPWCP to reach low-income children throughout the United States. Efficacy and success of implementation of the new packaged program will be tested in a one-arm pilot implementation study when delivered by community partners.

Abstract
BACKGROUND Surgical readmissions are clinically and financially problematic. Our purpose is to determine if a decrease in postoperative ambulation (steps/day) is associated with hospital readmission. METHODS In this prospective cohort study, patients undergoing elective operations wore an accelerometer activity tracker to measure steps/day for 28 consecutive postoperative days. The primary outcome was hospital readmission. The change in steps/day over two consecutive days prior to the day of the readmission were examined. Predetermined thresholds for decreases of consecutive daily ambulation levels were used to calculate sensitivity and specificity for the outcome of hospital readmission. RESULTS 215 patients (aged 63 ± 12 years) were included. Readmission occurred in 10% (n = 21). For each of the first 28-postoperative days, the entire cohort had an average daily step increase of 136 ± 146 steps/day (Spearman correlation rho = 0.990; p < 0.001). A decrease in steps for two consecutive days of >50% from the prior day had a 79% sensitivity and 90% specificity for hospital readmission. CONCLUSIONS A decrease of >50% daily ambulation (steps/day) over two consecutive post-discharge days accurately forecasts hospital readmission. The implications of these findings are that monitoring daily ambulation could serve as a form of outpatient telemetry aiding to forecast post-surgical readmissions.

Abstract
BACKGROUND There are few long-term studies of interventions to reduce in low socioeconomic status children with overweight or obesity. The Stanford GOALS trial evaluated a 3-year, community-based, multi-level, multi-setting, multi-component (MMM) systems intervention, to reduce weight gain among low socioeconomic status, Latinx children with overweight or obesity. METHODS We did a two-arm, parallel group, randomised, open-label, active placebo-controlled trial with masked assessment over 3 years. Families from low-income, primarily Latinx communities in Northern California, CA, USA, with 7-11-year-old children with overweight or obesity were randomly assigned to a MMM intervention or a Health Education (HE) comparison intervention. The MMM intervention included home environment changes and behavioural counselling, community after school team sports, and reports to primary health-care providers. The primary outcome was child BMI trajectory over three years. Secondary outcomes included one- and two-year changes in BMI. This trial is registered with ClinicalTrials.govNCT01642836. FINDINGS Between July 13, 2012, and Oct 3, 2013, 241 families were recruited and randomly assigned to MMM (n=120) or HE (n=121). Children's mean age was 9·5 (SD 1·4) years, 134 (56%) were female and 107 (44%) were male, and 236 (98%) were Latinx. 238 (99%) children participated in year 1, 233 (97%) in year 2, and 227 (94%) in year 3 of follow-up assessments. In intention-to-treat analysis, over 3 years, the difference between intervention groups in BMI trajectory was not significant (mean adjusted difference -0·25 [95% CI -0·90 to 0·40] kg/m2; Cohen's d=0.10; p=0·45). Children in the MMM intervention group gained less BMI over 1 year than did children in the HE intervention group (-0·73 [-1·07 to -0·39] kg/m2, d=0.55); the same was true over 2 years (-0·63 [-1·13 to -0·14] kg/m2; d =0.33). No differential adverse events were observed. INTERPRETATION The MMM intervention did not reduce BMI gain versus HE over 3 years but the effects over 1 and 2 years in this rigorous trial show the promise of this systems intervention approach for reducing weight gain and cardiometabolic risk factors in low socioeconomic status communities.

Abstract
OBJECTIVES/BACKGROUND The Geriatric Surgery Verification (GSV) Program promotes clinical standards aimed to optimize the quality of surgical care delivered to older adults. The purpose of this study was to determine if preliminary implementation of the GSV Program standards improves surgical outcomes. DESIGN Prospective study with cohort matching. SETTING Data from a single institution compared with a national data set cohort. PARTICIPANTS All patients aged ≥75 years undergoing inpatient operations between January 2018 and December 2019 were included. Cohort matching by age and procedure code was performed using a national data set. MEASUREMENTS Baseline pre- and intraoperative characteristics prospectively recorded using Veterans Affairs Surgical Quality Improvement Program (VASQIP) variable definitions. Postoperative outcomes were recorded including complications as defined by VASQIP, 30-day mortality, and length of stay. RESULTS A total of 162 patients participated in the GSV program, and 308 patients comprised the matched comparison group. There was no difference in postoperative occurrence of one or more complications (p = 0.81) or 30-day mortality (p = 0.61). Patients cared for by the GSV Program had a reduced postoperative length of stay (median 4 days [range 1,31] vs. 5 days [range 1,86]; p < 0.01; and mean 5.4 ± 4.8 vs. 8.8 ± 11.8 days; p < 0.01) compared with the matched cohort. In a multivariable regression model, the GSV Program's reduced length of stay was independent of other associated covariates including age, operative time, and comorbidities (p < 0.01). CONCLUSION Preliminary implementation of the GSV Program standards reduces length of stay in older adults undergoing inpatient operations. This finding demonstrates both the clinical and financial value of the GSV Program.

Abstract
Most methods used to make theory-relevant observations of technology use rely on self-report or application logging data where individuals' digital experiences are purposively summarized into aggregates meant to describe how the average individual engages with broadly defined segments of content. This aggregation and averaging masks heterogeneity in how and when individuals actually engage with their technology. In this study, we use screenshots (N > 6 million) collected every five seconds that were sequenced and processed using text and image extraction tools into content-, context-, and temporally-informative "screenomes" from 132 smartphone users over several weeks to examine individuals' digital experiences. Analyses of screenomes highlight extreme between-person and within-person heterogeneity in how individuals switch among and titrate their engagement with different content. Our simple quantifications of textual and graphical content and flow throughout the day illustrate the value screenomes have for the study of individuals' smartphone use and the cognitive and psychological processes that drive use. We demonstrate how temporal, textual, graphical, and topical features of people's smartphone screens can lay the foundation for expanding the Human Screenome Project with full-scale mining that will inform researchers' knowledge of digital life.

Abstract
Applying the Behavior Change Technique Taxonomy has the potential to facilitate identification of effective childhood obesity intervention components. This article evaluates the feasibility of coding Childhood Obesity Prevention and Treatment Consortium interventions and compares reliability between external taxonomy-familiar coders and internal intervention-familiar coders. After training, coder pairs independently coded prespecified portions of intervention materials. An adjudication process was used to explore coding discrepancies. Reliability between internal and external coders was moderate (prevalence and bias-adjusted kappa .38 to .55). Reliability for specific target behaviors varied with substantial agreement for physical activity (.63 to .76) and moderate for dietary intake (.44 to .63). Applying the taxonomy to these interventions was feasible, but agreement was modest. Coding discrepancies highlight the importance of refining coding to capture the complexities of childhood obesity interventions, which often engage multiple recipients (e.g., parents and/or children) and address multiple behaviors (e.g., diet, physical activity, screen time).

Abstract
Objective: To evaluate the efficacy of childhood obesity interventions and conduct a taxonomy of intervention components that are most effective in changing obesity-related health outcomes in children 2-5 years of age. Methods: Comprehensive searches located 51 studies from 18,335 unique records. Eligible studies: (1) assessed children aged 2-5, living in the United States; (2) evaluated an intervention to improve weight status; (3) identified a same-aged comparison group; (4) measured BMI; and (5) were available between January 2005 and August 2019. Coders extracted study, sample, and intervention characteristics. Effect sizes [ESs; and 95% confidence intervals (CIs)] were calculated by using random-effects models. Meta-regression was used to determine which intervention components explain variability in ESs. Results: Included were 51 studies evaluating 58 interventions (N = 29,085; mean age = 4 years; 50% girls). Relative to controls, children receiving an intervention had a lower BMI at the end of the intervention (g = 0.10, 95% CI = 0.02-0.18; k = 55) and at the last follow-up (g = 0.17, 95% CI = 0.04-0.30; k = 14; range = 18-143 weeks). Three intervention components moderated efficacy: engage caregivers in praise/encouragement for positive health-related behavior; provide education about the importance of screen time reduction to caregivers; and engage pediatricians/health care providers. Conclusions: Early childhood obesity interventions are effective in reducing BMI in preschool children. Our findings suggest that facilitating caregiver education about the importance of screen time reduction may be an important strategy in reducing early childhood obesity.

Abstract
Meta-analysis has been used to examine the effectiveness of childhood obesity prevention efforts, yet traditional conventional meta-analytic methods restrict the kinds of studies included, and either narrowly define mechanisms and agents of change, or examine the effectiveness of whole interventions as opposed to the specific actions that comprise interventions. Taxonomic meta-analytic methods widen the aperture of what can be included in a meta-analysis data set, allowing for inclusion of many types of interventions and study designs. The National Collaborative on Childhood Obesity Research Childhood Obesity Evidence Base (COEB) project focuses on interventions intended to prevent childhood obesity in children 2-5 years old who have an outcome measure of BMI. The COEB created taxonomies, anchored in the Social Ecological Model, which catalog specific outcomes, intervention components, intended recipients, and contexts of policies, initiatives, and interventions conducted at the individual, interpersonal, organizational, community, and societal level. Taxonomies were created by discovery from the literature itself using grounded theory. This article describes the process used for a novel taxonomic meta-analysis of childhood obesity prevention studies between the years 2010 and 2019. This method can be applied to other areas of research, including obesity prevention in additional populations.

Postoperative delirium is associated with decreased recovery of ambulation one-month after surgery. Am J Surg 2020; 221:856-861. [PMID: 32933746 DOI: 10.1016/j.amjsurg.2020.08.031] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 08/21/2020] [Accepted: 08/25/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND We hypothesized that postoperative delirium is associated with diminished recovery toward baseline preoperative ambulation levels one-month postoperatively. METHODS Patients included were ≥60 years old undergoing inpatient operations. Ambulation was measured as steps/day using an accelerometer worn for ≥3-days preoperatively and ≥28-days postoperatively. Primary outcome was the percent recovery of preoperative steps. RESULTS 109 patients were included; 17 (16%) developed postoperative delirium. Recovery of ambulation toward preoperative baseline at postoperative day-28 was decreased in delirium group (34% vs. 69%; p < 0.01). Immediate postoperative ambulation was similar in the delirium vs. no-delirium groups (p = 0.79). Delirium occurred on average on postoperative 3 ± 4 days. Subsequently, ambulation was decreased in the delirium group compared to non-delirium group at postoperative week-1 (p = 0.01), week-2 (p = 0.02), week-3 (p < 0.01) and week-4 (p < 0.01). CONCLUSION Patients undergoing inpatient operations who develop delirium recover only one-third of their baseline steps one-month postoperatively. Postoperative delirium results in a decreased recovery towards baseline ambulation for at least 4-weeks following major operations in comparison to non-delirious patients. The decrease in ambulation in the delirium versus no-delirium groups occurred after the occurrence of postoperative delirium.

Electromagnetic interference on cardiac pacemakers and implantable cardioverter defibrillators during endoscopy as reported to the US Federal Drug Administration. Surg Endosc 2020; 35:3796-3801. [PMID: 32804270 DOI: 10.1007/s00464-020-07872-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Accepted: 08/05/2020] [Indexed: 11/26/2022]
Abstract
INTRODUCTION More than 3 million patients have a cardiac implanted electronic device (CIED) such as a pacemaker or implanted cardioverter-defibrillator in the USA. These devices are susceptible to electromagnetic interference (EMI) leading to malfunction and injury. Radiofrequency energy, the most common modality for obtaining hemostasis during endoscopy, is the most common source of EMI. Few studies have evaluated the effect of endoscopic radiofrequency energy on CIEDs. We aim to characterize CIED dysfunction related to endoscopic procedures. We hypothesize that EMI from endoscopic energy can result in patient injury. METHODS We queried the Manufacturer and User Facility Device Experience (MAUDE) database for CIED dysfunction related to electrosurgical devices over a 10-year period (2009-2019). CIED dysfunction events were identified using seven problem codes (malfunction, electromagnetic interference, ambient noise, pacing problem, over-sensing, inappropriate shock, defibrillation). These were cross-referenced for the terms "cautery, electrocautery, endoscopy, esophagus, colonoscopy, colon, esophagoscopy, and esophagogastroduodenoscopy." Reports were individually reviewed to confirm and characterize CIED malfunction due to an endoscopic procedure. RESULTS A search for CIED dysfunction resulted in 43,759 reports. Three hundred and eleven reports (0.7%) were associated with electrocautery, and of these, 45 reports (14.5%) included endoscopy. Ten reports involving endoscopy (22%) specified upper (3, 7%) or lower (7, 16%) endoscopy while the remainder were non-specific. Twenty-six of reports involving endoscopy (58%) suffered injury because of CIED dysfunction: Of these, 17 (65%) received inappropriate shocks, 5 (19%) had pacing inhibition with bradycardia or asystole, 3 (12%) had CIED damage requiring explant and replacement, and 1 (4%) patient suffered ventricular tachycardia requiring hospital admission. CONCLUSION The use of energy during endoscopy can cause dysfunction of CIEDs. This most commonly results in inappropriate defibrillation, symptomatic bradycardia, and asystole. Patients with CIEDs undergoing endoscopy should undergo pre- and post-procedure device interrogation and re-programming to avoid patient injury.

Stray energy transfer in single-incision robotic surgery. Surg Endosc 2020; 35:2981-2985. [PMID: 32591940 DOI: 10.1007/s00464-020-07742-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Accepted: 06/12/2020] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Stray energy transfer from surgical monopolar radiofrequency energy instruments can cause unintended thermal injuries during laparoscopic surgery. Single-incision laparoscopic surgery transfers more stray energy than traditional laparoscopic surgery. There is paucity of published data concerning stray energy during single-incision robotic surgery. The purpose of this study was to quantify stray energy transfer during traditional, multiport robotic surgery (TRS) compared to single-incision robotic surgery (SIRS). METHODS An in vivo porcine model was used to simulate a multiport or single-incision robotic cholecystectomy (DaVinci Si, Intuitive Surgical, Sunnyvale, CA). A 5 s, open air activation of the monopolar scissors was done on 30 W and 60 W coag mode (ForceTriad, Covidien-Medtronic, Boulder, CO) and Swift Coag effect 3, max power 180 W (VIO 300D, ERBE USA, Marietta, GA). Temperature of the tissue (°C) adjacent to the tip of the assistant grasper or the camera was measured with a thermal camera (E95, FLIR Systems, Wilsonville, OR) to quantify stray energy transfer. RESULTS Stray energy transfer was greater in the SIRS setup compared to TRS setup at the assistant grasper (11.6 ± 3.3 °C vs. 8.4 ± 1.6 °C, p = 0.013). Reducing power from 60 to 30 W significantly reduced stray energy transfer in SIRS (15.3 ± 3.4 °C vs. 11.6 ± 3.3 °C, p = 0.023), but not significantly for TRS (9.4 ± 2.5 °C vs. 8.4 ± 1.6 °C, p = 0.278). The use of a constant voltage regulating generator also minimized stray energy transfer for both SIRS (0.7 ± 0.4 °C, p < 0.001) and TRS (0.7 ± 0.4 °C, p < 0.001). CONCLUSIONS More stray energy transfer occurs during single-incision robotic surgery than multiport robotic surgery. Utilizing a constant voltage regulating generator minimized stray energy transfer for both setups. These data can be used to guide robotic surgeons in their use of safe, surgical energy.

Abstract
INTRODUCTION Stray energy transfer from monopolar radiofrequency energy during laparoscopy can be potentially catastrophic. Robotic surgery is increasing in popularity; however, the risk of stray energy transfer during robotic surgery is unknown. The purpose of this study was to (1) quantify stray energy transfer using robotic instrumentation, (2) determine strategies to minimize the transfer of energy, and (3) compare robotic stray energy transfer to laparoscopy. METHODS In a laparoscopic trainer, a monopolar instrument (L-hook) was activated with DaVinci Si (Intuitive, Sunnyvale, CA) robotic instruments. A camera and assistant grasper were inserted to mimic a minimally invasive cholecystectomy. During activation of the L-hook, the non-electric tips of the camera and grasper were placed adjacent to simulated tissue (saline-soaked sponge). The primary outcome was change in temperature from baseline (°C) measured nearest the tip of the non-electric instrument. RESULTS Simulated tissue nearest the robotic grasper increased an average of 18.3 ± 5.8 °C; p < 0.001 from baseline. Tissue nearest the robotic camera tip increased (9.0 ± 2.1 °C; p < 0.001). Decreasing the power from 30 to 15 W (18.3 ± 5.8 vs. 2.6 ± 2.7 °C, p < 0.001) or using low-voltage cut mode (18.3 ± 5.8 vs. 3.1 ± 2.1 °C, p < 0.001) reduced stray energy transfer to the robotic grasper. Desiccating tissue, in contrast to open air activation, also significantly reduced stray energy transfer for the grasper (18.3 ± 5.8 vs. 0.15 ± 0.21 °C, p < 0.001) and camera (9.0 ± 2.1 vs. 0.24 ± 0.34 °C, p < 0.001). CONCLUSIONS Stray energy transfer occurs during robotic surgery. The assistant grasper carries the highest risk for thermal injury. Similar to laparoscopy, stray energy transfer can be reduced by lowering the power setting, utilizing a low-voltage cut mode instead of coagulation mode and avoiding open air activation. These practical findings can aid surgeons performing robotic surgery to reduce injuries from stray energy.

Abstract
Despite the rising incidence of childhood obesity, international data from Eurostat show that the prevalence of obesity among those aged 15-19 years remains under 5%, which offers an important opportunity for preventing subsequent adult obesity. Young people engage poorly, even obstructively, with conventional health initiatives and are often considered 'hard to reach'. However, when approached in the language of youth, via IT, they express great concern, and unwanted weight gain in young people can be prevented by age-appropriate, independent, online guidance. Additionally, when shown online how 'added value' by industry can generate consumer harms as free market 'externalities', and how obesogenic 'Big Food' production and distribution incur environmental and ethical costs, young people make lasting behavioural changes that attenuate weight gain. This evidence offers a novel approach to obesity prevention, handing the initiative to young people themselves and supporting them with evidence-based methods to develop, propagate and 'own' social movements that can simultaneously address the geopolitical concerns of youth and obesity prevention.

Reducing meat consumption by appealing to animal welfare: protocol for a meta-analysis and theoretical review. Syst Rev 2020; 9:3. [PMID: 31907028 PMCID: PMC6945605 DOI: 10.1186/s13643-019-1264-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Accepted: 12/20/2019] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Reducing meat consumption may improve human health, curb environmental damage and greenhouse gas emissions, and limit the large-scale suffering of animals raised in factory farms. Previous work has begun to develop interventions to reduce individual meat consumption, often by appealing directly to individual health motivations. However, research on nutritional behavior change suggests that interventions additionally linking behavior to ethical values, identity formation, and existing social movements may be particularly effective and longer-lasting. Regarding meat consumption, preliminary evidence and psychological theory suggest that appeals related to animal welfare may have considerable potential to effectively leverage these elements of human psychology. We aim to conduct a systematic review and quantitative meta-analysis evaluating the effectiveness of animal welfare-related appeals on actual or intended meat consumption or purchasing. Our investigation will critically synthesize the current state of knowledge regarding psychological mechanisms of intervening on individual meat consumption and empirically identify the psychological characteristics underlying the most effective animal welfare-based interventions. METHODS We will systematically search eight academic databases and extensively search unpublished grey literature. We will include studies that assess interventions intended to reduce meat consumption or purchase through the mention or portrayal of animal welfare, that measure outcomes related to meat consumption or purchase, and that have a control condition. Eligible studies may recruit from any human population, be written in any language, and be published or released any time. We will meta-analyze the studies, reporting the pooled point estimate and additional metrics that describe the distribution of potentially heterogeneous effects. We will assess studies' risk of bias and conduct sensitivity analyses for publication bias. We describe possible follow-up analyses to investigate hypothesized moderators of intervention effectiveness. DISCUSSION The findings of the proposed systematic review and meta-analysis, including any identified methodological limitations of the existing literature, could inform the design of successful evidence-based interventions with broad potential to improve human, animal, and environmental well-being. SYSTEMATIC REVIEW REGISTRATION The protocol was preregistered via the Open Science Framework (https://osf.io/d3y56/registrations).

Abstract
AIMS This study describes when and how adolescents engage with their fast-moving and dynamic digital environment as they go about their daily lives. We illustrate a new approach - screenomics - for capturing, visualizing, and analyzing screenomes, the record of individuals' day-to-day digital experiences. SAMPLE Over 500,000 smartphone screenshots provided by four Latino/Hispanic youth, age 14-15 years, from low-income, racial/ethnic minority neighborhoods. METHOD Screenomes collected from smartphones for one to three months, as sequences of smartphone screenshots obtained every five seconds that the device is activated, are analyzed using computational machinery for processing images and text, machine learning algorithms, human-labeling, and qualitative inquiry. FINDINGS Adolescents' digital lives differ substantially across persons, days, hours, and minutes. Screenomes highlight the extent of switching among multiple applications, and how each adolescent is exposed to different content at different times for different durations - with apps, food-related content, and sentiment as illustrative examples. IMPLICATIONS We propose that the screenome provides the fine granularity of data needed to study individuals' digital lives, for testing existing theories about media use, and for generation of new theory about the interplay between digital media and development.

Abstract
PURPOSE Our purpose was to create a content domain framework for delirium severity to inform item development for a new instrument to measure delirium severity. METHODS We used an established, multi-stage instrument development process during which expert panelists discussed best approaches to measure delirium severity and identified related content domains. We conducted this work as part of the Better ASsessment of ILlness (BASIL) study, a prospective, observational study aimed at developing and testing measures of delirium severity. Our interdisciplinary expert panel consisted of twelve national delirium experts and four expert members of the core research group. Over a one-month period, experts participated in two rounds of review. RESULTS Experts recommended that the construct of delirium severity should reflect both the phenomena and the impact of delirium to create an accurate, patient-centered instrument useful to interdisciplinary clinicians and family caregivers. Final content domains were Cognitive, Level of consciousness, Inattention, Psychiatric-Behavioral, Emotional dysregulation, Psychomotor features, and Functional. Themes debated by experts included reconciling clinical geriatrics and psychiatric content, mapping symptoms to one specific domain, and accurate capture of unclear clinical presentations. CONCLUSIONS We believe this work represents the first application of instrument development science to delirium. The identified content domains are inclusive of various, wide-ranging domains of delirium severity and are reflective of a consistent framework that relates delirium severity to potential clinical outcomes. Our content domain framework provides a foundation for development of delirium severity instruments that can help improve care and quality of life for patients with delirium.

Recruitment strategies for predominantly low-income, multi-racial/ethnic children and parents to 3-year community-based intervention trials: Childhood Obesity Prevention and Treatment Research (COPTR) Consortium. Trials 2019; 20:296.

Abstract
BACKGROUND The recruitment of participants into community-based randomized controlled trials studying childhood obesity is often challenging, especially from low-income racial/ethnical minorities and when long-term participant commitments are required. This paper describes strategies used to recruit and enroll predominately low-income racial/ethnic minority parents and children into the Childhood Obesity Prevention and Treatment Research (COPTR) consortium. METHODS The COPTR consortium has run four independent 3-year, multi-level (individual, family, school, clinic, and community) community-based randomized controlled trials. Two were prevention trials in preschool children and the other two were treatment trials in pre-adolescents and adolescent youth. All trials reported monthly participant recruitment numbers using a standardized method over the projected 18-24 months of recruitment. After randomization of participants was completed, recruitment staff and investigators from each trial retrospectively completed a survey of recruitment strategies and their perceived top three recruitment strategies and barriers. RESULTS Recruitment was completed in 15-21 months across trials, enrolling a total of 1745 parent-child dyads- out of 6314 screened. The number of children screened per randomized child was 4.6 and 3.5 in the two prevention trials, and 3.1 and 2.5 in the two treatment trials. Recruitment strategies reported included: (1) careful planning, (2) working with trusting community partners, (3) hiring recruitment staff who were culturally sensitive, personality appropriate, and willing to work flexible hours, (4) contacting potential participants actively and repeatedly, (5) recruiting at times and locations convenient for participants, (6) providing incentives to participants to complete baseline measures, (7) using a tracking database, (8) evaluating whether participants understand the activities and expectations of the study, and (9) assessing participants' motivation for participating. Working with community partners, hiring culturally sensitive staff, and contacting potential participants repeatedly were cited by two trials among their top three strategies. The requirement of a 3-year commitment to the trial was cited by two trials to be among the top three recruitment barriers. CONCLUSIONS Comprehensive strategies that include community partnership support, culturally sensitive recruitment staff, and repeated contacts with potential participants can result in successful recruitment of low-income racial/ethnic minority families into obesity prevention and treatment trials.

Abstract
Frailty has long been an important concept in the practice of geriatric medicine and in gerontological research, but integration and implementation of frailty concepts into clinical practice in the United States has been slow. The National Institute on Aging (NIA) Intramural Research Program and the Johns Hopkins Older Americans Independence Center sponsored a symposium to identify potential barriers that impede the movement of frailty into clinical practice and to highlight opportunities to facilitate the further integration of frailty into clinical practice. Primary and subspecialty care providers, and investigators working to integrate and translate new biological aging knowledge into more specific preventive and treatment strategies for frailty provided the meeting content. Recommendations included a call for more specific language that clarifies conceptual differences between frailty definitions and measurement tools; the development of randomized controlled trials to test whether specific intervention strategies for a variety of conditions differently affect frail and non-frail individuals; development of implementation studies and therapeutic trials aimed at tailoring care as a function of pragmatic frailty markers; the use of deep learning and dynamic systems approaches to improve the translatability of findings from epidemiological studies; and the incorporation of advances in aging biology, especially focused on mitochondria, stem cells, and senescent cells, toward the further development of biologically targeted intervention and prevention strategies that can be used to treat or prevent frailty.

Abstract
Importance Autism behavioral therapy is effective but expensive and difficult to access. While mobile technology-based therapy can alleviate wait-lists and scale for increasing demand, few clinical trials exist to support its use for autism spectrum disorder (ASD) care. Objective To evaluate the efficacy of Superpower Glass, an artificial intelligence-driven wearable behavioral intervention for improving social outcomes of children with ASD. Design, Setting, and Participants A randomized clinical trial in which participants received the Superpower Glass intervention plus standard of care applied behavioral analysis therapy and control participants received only applied behavioral analysis therapy. Assessments were completed at the Stanford University Medical School, and enrolled participants used the Superpower Glass intervention in their homes. Children aged 6 to 12 years with a formal ASD diagnosis who were currently receiving applied behavioral analysis therapy were included. Families were recruited between June 2016 and December 2017. The first participant was enrolled on November 1, 2016, and the last appointment was completed on April 11, 2018. Data analysis was conducted between April and October 2018. Interventions The Superpower Glass intervention, deployed via Google Glass (worn by the child) and a smartphone app, promotes facial engagement and emotion recognition by detecting facial expressions and providing reinforcing social cues. Families were asked to conduct 20-minute sessions at home 4 times per week for 6 weeks. Main Outcomes and Measures Four socialization measures were assessed using an intention-to-treat analysis with a Bonferroni test correction. Results Overall, 71 children (63 boys [89%]; mean [SD] age, 8.38 [2.46] years) diagnosed with ASD were enrolled (40 [56.3%] were randomized to treatment, and 31 (43.7%) were randomized to control). Children receiving the intervention showed significant improvements on the Vineland Adaptive Behaviors Scale socialization subscale compared with treatment as usual controls (mean [SD] treatment impact, 4.58 [1.62]; P = .005). Positive mean treatment effects were also found for the other 3 primary measures but not to a significance threshold of P = .0125. Conclusions and Relevance The observed 4.58-point average gain on the Vineland Adaptive Behaviors Scale socialization subscale is comparable with gains observed with standard of care therapy. To our knowledge, this is the first randomized clinical trial to demonstrate efficacy of a wearable digital intervention to improve social behavior of children with ASD. The intervention reinforces facial engagement and emotion recognition, suggesting either or both could be a mechanism of action driving the observed improvement. This study underscores the potential of digital home therapy to augment the standard of care. Trial Registration ClinicalTrials.gov identifier: NCT03569176.

Abstract
Digital experiences capture an increasingly large part of life, making them a preferred, if not required, method to describe and theorize about human behavior. Digital media also shape behavior by enabling people to switch between different content easily, and create unique threads of experiences that pass quickly through numerous information categories. Current methods of recording digital experiences provide only partial reconstructions of digital lives that weave - often within seconds - among multiple applications, locations, functions and media. We describe an end-to-end system for capturing and analyzing the "screenome" of life in media, i.e., the record of individual experiences represented as a sequence of screens that people view and interact with over time. The system includes software that collects screenshots, extracts text and images, and allows searching of a screenshot database. We discuss how the system can be used to elaborate current theories about psychological processing of technology, and suggest new theoretical questions that are enabled by multiple time scale analyses. Capabilities of the system are highlighted with eight research examples that analyze screens from adults who have generated data within the system. We end with a discussion of future uses, limitations, theory and privacy.
