Predicting ranger attrition

Elite military programs such as the 75th Ranger Regiment's Ranger Assessment and Selection Program (RASP) see rates of attrition often in excess of 50%, and amplify the need to identify and screen candidates based on their probability of successful matriculation. Models were developed (and cross-validated) to predict attrition from RASP using the physical abilities, cognitive abilities, and personality scores collected during candidate admissions screening. We report both regression weights and standardized odds ratios for optimum models of candidate success over three program timeframes to enable an understanding of the relative importance of each predictor. In spite of physical abilities scores being used to select RASP candidates, they were the strongest predictors of RASP attrition. Personality scores accounted for more variance in predicting candidate success than cognitive ability scores. Personality predictors, especially dimensions related to Openness, were better at predicting week one attrition than attrition in later weeks. The use of a single, aggregated candidate probability score for making admissions decisions is discussed, along with additional practical and scientific implications.

Long-term follow-up of web-based and group-based behavioural intervention in NAFLD in a real world clinical setting

BACKGROUND

The long-term results of web-based behavioural intervention in non-alcoholic fatty liver disease (NAFLD) have not been described in patients followed in specialised centres.

AIMS

To analyse the long-term effectiveness of web education compared with the results achieved by a group-based behavioural intervention in the same years 2012-2014.

METHODS

We followed 679 patients with NAFLD (web-based, n = 290; group-based, n = 389) for 5 years. Weight loss ≥10% was the primary outcome; secondary outcomes were attrition, changes in liver enzymes and in biomarkers of steatosis (Fatty liver Index) and fibrosis (Fibrosis-4 index).

RESULTS

The cohorts differed in age, education, working status and presence of diabetes. Attrition was higher in the web-based cohort (hazard ratio: 1.53; 95% CI: 1.24-1.88), but not different after adjustment for confounders. Among patients in active follow-up, 50% lost ≥5% of initial body weight and 19% lost ≥10%, without difference between cohorts. Alanine aminotransferase levels fell to within the normal range in 51% and 45% of web- and group-based cohorts, respectively. Fatty Liver Index declined progressively and, by year 5, it ruled out steatosis in 4.8%, whereas 24.9% were in the indeterminate range. Fibrosis-4 index increased in both cohorts, driven by age, but the prevalence of cases ruling-in advanced fibrosis remained very low (around 1%). Improvements in the class of both surrogate biomarkers were associated with ≥5% weight loss.

CONCLUSIONS

Although burdened by attrition, web-based behavioural intervention is feasible and effective in NAFLD, expanding the cohort involved in behavioural programs and reducing the risk of progressive disease.

Quantifying uptake and completion of pulmonary rehabilitation programs in people with chronic obstructive pulmonary disease known to tertiary care

BACKGROUND

People with symptomatic chronic obstructive pulmonary disease (COPD) benefit from pulmonary rehabilitation programs (PRPs), but program attrition is common.

METHODS

For people with COPD who presented to tertiary care and appeared appropriate for a PRP, we prospectively mapped their PRP journey, explored factors influencing attendance to pre-program assessment and captured program attrition.

RESULTS

Of the 391 participants, 31% (95% CI 27 to 36) were referred to a PRP (n = 123; age 68 ± 10years, 62 males [50%], FEV1 45 ± 19%predicted). Of those referred, 94 (76% [69 to 84]) attended a pre-program assessment. Ex-smokers and those who had a healthcare professional (HCP) explain they would be referred were more likely to attend a pre-program assessment (odds ratio [95%CI]; 2.6 [1.1 to 6.1]; and 4.7 [1.9 to 11.7], respectively). Of the 94 who attended, 63 (67% [58 to 77]) commenced; and of those who commenced, 35 (56% [43 to 68]) completed a PRP. All who completed (n = 35, 100%) were provided at least one strategy to maintain training-related gains.

CONCLUSION

Attrition occurs throughout the PRP journey. Interactions with HCPs about PRPs positively influenced attendance. Understanding how HCPs can best contextualise PRPs to encourage referral acceptance and uptake is an important area for further work.

Full Mouth Rehabilitation for a Patient With Generalized Attrition: The Hobo Technique in Action

This case report addresses the critical issue of severe tooth wear and its impact on the vertical dimension of occlusion in a 75-year-old patient. The patient presented with worn-down teeth, chewing difficulties, and aesthetic concerns, prompting a comprehensive treatment plan utilizing the Hobo twin-stage technique. The approach involved careful diagnosis, root canal therapy, and the creation of provisional restorations, monitored through an occlusal splint. The prosthetic phase incorporated strategically designed porcelain-fused-to-metal crowns, aiming for optimal tooth alignment and balanced movement. The successful outcome not only restored function and aesthetics but also enhanced the patient's confidence. This case underscores the effectiveness of a systematic approach in managing severe tooth wear, emphasizing the importance of regular follow-ups and good oral hygiene for long-term success.

Protocol optimization and reducing dropout in online research

Online research has advantages over in-person research; it's cost-efficient, scalable, and may increase diversity. Researchers collecting data online can assess protocol performance with classification models like a decision tree. However, challenges include attrition, lack of testing environment controls, technical limitations, and lack of face-to-face rapport and real time feedback. It is necessary to consider human factors of the teleresearch process from recruitment to data collection. Here we document the impact of protocol optimizations on social media engagement and retention between a pilot sample of Veterans (n = 26) and a post-optimization sample of both Veterans and civilians (n = 220) recruited from Facebook advertisements. Two-sided tests for equality of proportions were statistically significant: advertisement views leading to clicks increased by 23.8% [X2(1) = 130.3, p < 0.001] and completion of behavioral tasks increased by 31.2% [X2(1) = 20.74, p < 0.001]. However, a proportion of participants dropped out of the study before completion for both samples. To explore why, a C5.0 decision tree was used to find features that classify participant dropout. The features chosen by the algorithm were nicotine use (100%) and cannabis use (25.6%). However, for those completing the study, data quality of cognitive performance was similar for users and nonusers. Rather than determining eligibility, participants who endorse using nicotine, or both nicotine and cannabis, may have individual differences that require support in online protocols to reduce drop out, such as extra breaks. An introduction page that humanizes participants' lifestyle habits as a naturalistic benefit of remote research may also be helpful. Strategies are discussed to increase engagement and improve data quality. The findings have implications for the feasibility of conducting remote research, an increasingly popular approach that has distinct challenges compared to in-person studies.

Combined ventricular dysfunction and atrioventricular valve regurgitation after the Norwood procedure are associated with attrition prior to superior cavopulmonary connection

Background

Infants with hypoplastic left heart syndrome (HLHS) or a variant are at risk of ventricular dysfunction (VD) and atrioventricular valve regurgitation (AVVR) prior to superior cavopulmonary connection (SCPC). Although the impact of these complications in isolation has been described, their effect in combination on attrition is poorly defined.

Methods

A retrospective observational study of patients with HLHS or variants undergoing a Norwood procedure between 2008 and 2020 at a single center was performed. VD and AVVR were defined as moderate or severe when seen on 2 sequential echocardiograms outside the perioperative period. Attrition was defined as death, listing for heart transplant, or unsuitability for SCPC or transplant. Descriptive statistics and regression models were used for analysis.

Results

A total of 397 patients were included, of whom 75% had HLHS and 57% had received a Blalock-Thomas-Taussig shunt. Isolated VD occurred in 9% of patients, AVVR occurred in 13%, and both occurred in 6%. Attrition prior to SCPC occurred in 19% of the overall cohort, in 52% of patients with combined VD and AVVR (odds ratio [OR], 5.2; 95% confidence interval [CI], 2.3-12.0; P < .01), 26% of those with VD (OR, 1.5; 95% CI, 0.7-3.3; P = .32), 25% of those with AVVR (OR, 1.5; 95% CI, 0.7-2.9; P = .27), and 15% in those with neither (OR, 0.3; 95% CI, 0.2-0.6; P < .01). Other factors associated with attrition included prematurity, total bypass time at Norwood, and extracorporeal membrane oxygenation after Norwood, whereas later year of Norwood was protective (P < .01 for all).

Conclusions

The presence of combined VD and AVVR markedly increases the likelihood of attrition prior to SCPC, identifying a high-risk group.

Evaluating a Remote Monitoring Program for Respiratory Diseases: Prospective Observational Study

BACKGROUND

Patients with chronic respiratory diseases and those in the postdischarge period following hospitalization because of COVID-19 are particularly vulnerable, and little is known about the changes in their symptoms and physiological parameters. Continuous remote monitoring of physiological parameters and symptom changes offers the potential for timely intervention, improved patient outcomes, and reduced health care costs.

OBJECTIVE

This study investigated whether a real-time multimodal program using commercially available wearable technology, home-based Bluetooth-enabled spirometers, finger pulse oximeters, and smartphone apps is feasible and acceptable for patients with chronic respiratory diseases, as well as the value of low-burden, long-term passive data collection.

METHODS

In a 3-arm prospective observational cohort feasibility study, we recruited 60 patients from the Royal Free Hospital and University College Hospital. These patients had been diagnosed with interstitial lung disease, chronic obstructive pulmonary disease, or post-COVID-19 condition (n=20 per group) and were followed for 180 days. This study used a comprehensive remote monitoring system designed to provide real-time and relevant data for both patients and clinicians. Data were collected using REDCap (Research Electronic Data Capture; Vanderbilt University) periodic surveys, Remote Assessment of Disease and Relapses-base active app questionnaires, wearables, finger pulse oximeters, smartphone apps, and Bluetooth home-based spirometry. The feasibility of remote monitoring was measured through adherence to the protocol, engagement during the follow-up period, retention rate, acceptability, and data integrity.

RESULTS

Lowest-burden passive data collection methods, via wearables, demonstrated superior adherence, engagement, and retention compared with active data collection methods, with an average wearable use of 18.66 (SD 4.69) hours daily (77.8% of the day), 123.91 (SD 33.73) hours weekly (72.6% of the week), and 463.82 (SD 156.70) hours monthly (64.4% of the month). Highest-burden spirometry tasks and high-burden active app tasks had the lowest adherence, engagement, and retention, followed by low-burden questionnaires. Spirometry and active questionnaires had the lowest retention at 0.5 survival probability, indicating that they were the most burdensome. Adherence to and quality of home spirometry were analyzed; of the 7200 sessions requested, 4248 (59%) were performed. Of these, 90.3% (3836/4248) were of acceptable quality according to American Thoracic Society grading. Inclusion of protocol holidays improved retention measures. The technologies used were generally well received.

CONCLUSIONS

Our findings provide evidence supporting the feasibility and acceptability of remote monitoring for capturing both subjective and objective data from various sources for respiratory diseases. The high engagement level observed with passively collected data suggests the potential of wearables for long-term, user-friendly remote monitoring in respiratory disease management. The unique piloting of certain features such as protocol holidays, alert notifications for missing data, and flexible support from the study team provides a reference for future studies in this field.

The Effectiveness of the StaySafe Intervention Using a Paradigm for Predicting Missing Outcome Data

Sample attrition is a confounding issue in the analysis of data collected in follow-up studies. The present study uses a regression procedure that includes a propensity score as a predictor in estimating imputed data. The utility of the procedure was addressed by comparing results from this augmented data with those from the original data. Data were from a randomized controlled study testing the utility of a tablet-based intervention designed to improve decision-making with respect to health risk behaviors. Outcomes included self-reported testing for HIV, STD, and hepatitis. Two samples were used (163 in community facilities and 348 in residential facilities). Seventy-eight in the community sample and 238 in the residential sample completed follow-up surveys. Propensity scores based on a stepwise logistic regression were used to make the calibration sample and the missing data sample as close as possible. Multilevel analysis was performed for each outcome and multiple imputation compared estimated mean differences for the augmented and original analyses. The model imputing missing data was effective for the three outcomes and increased power. Least square mean differences between augmented and original data appeared to be essentially the same for most of the outcomes. This protocol has been registered with https://www.clinicaltrials.gov/(NCT02777086).

Cognitive behavioral therapy for insomnia treatment attrition in patients with weekly nightmares

STUDY OBJECTIVES

This study's objective was to evaluate the effect of nightmares (NMs) on attrition and symptom change following cognitive behavioral therapy for insomnia (CBT-I) treatment using data from a successful CBT-I randomized controlled trial delivered to participants with recent interpersonal violence exposure.

METHODS

The study randomized 110 participants (107 women; mean age: 35.5 years) to CBT-I or to an attention-control group. Participants were assessed at 3 time periods: baseline, post-CBT-I (or attention control), and at time 3 (T3) post-cognitive processing therapy received by all participants. NM reports were extracted from the Fear of Sleep Inventory. Participants with weekly NMs were compared with those with fewer than weekly NMs on outcomes including attrition, insomnia, posttraumatic stress disorder, and depression. Change in NM frequency was examined.

RESULTS

Participants with weekly NMs (55%) were significantly more likely to be lost to follow-up post-CBT-I (37%) compared with participants with infrequent NMs (15.6%) and were less likely to complete T3 (43%) than patients with less frequent NMs (62.5%). NMs were unrelated to differential treatment response in insomnia, depression, or posttraumatic stress disorder. Treatment with CBT-I was not associated with reduced NM frequency; however, change in sleep-onset latency from post-CBT-I to T3 predicted fewer NMs at T3.

CONCLUSIONS

Weekly NMs were associated with attrition but not a reduced change in insomnia symptoms following CBT-I. NM symptoms did not change as a function of CBT-I, but change in sleep-onset latency predicted lower NM frequency. CBT-I trials should screen for NMs and consider augmenting CBT-I to specifically address NMs.

Emergency medicine physician workforce attrition differences by age and gender

BACKGROUND

Emergency care workforce concerns have gained national prominence given recent data suggesting higher than previously estimated attrition. With little known regarding characteristics of physicians leaving the workforce, we sought to investigate the age and number of years since residency graduation at which male and female emergency physicians (EPs) exhibited workforce attrition.

METHODS

We performed a repeated cross-sectional analysis of EPs reimbursed by Medicare linked to date of birth and residency graduation date data from the American Board of Emergency Medicine for the years 2013-2020. Stratified by gender, our primary outcomes were the median age and number of years since residency graduation at the time of attrition, defined as the last year during the study time frame that an EP provided clinical services. We constructed a multivariate logistic regression model to examine the association between gender and EP workforce attrition.

RESULTS

A total of 25,839 (70.2%) male and 10,954 (29.8%) female EPs were included. During the study years, 5905 male EPs exhibited attrition at a median (interquartile range [IQR]) age of 56.4 (44.5-65.4) years, and 2463 female EPs exhibited attrition at a median (IQR) age of 44.0 (38.0-53.9) years. Female gender (adjusted odds ratio 2.30, 95% confidence interval 1.82-2.91) was significantly associated with attrition from the workforce. Male and female EPs had respective median (IQR) post-residency graduation times in the workforce of 17.5 (9.5-25.5) years and 10.5 (5.5-18.5) years among those who exhibited attrition and one in 13 males and one in 10 females exited clinical practice within 5 years of residency graduation.

CONCLUSIONS

Female physicians exhibited attrition from the EM workforce at an age approximately 12 years younger than male physicians. These data identify widespread disparities regarding EM workforce attrition that are critical to address to ensure stability, longevity, and diversity in the EP workforce.

Attrition rate and predictors of a monitoring mHealth application in adolescents with obesity

BACKGROUND

Integrating mobile health (mHealth) into paediatric obesity treatment can provide opportunities for more personalized and lifetime treatment. However, high attrition rates pose a significant challenge. The current study attempts to better understand attrition by exploring (1) attrition rates of a monitoring mHealth application for usage over 14 days and (2) testing predictors of attrition in adolescents with obesity.

METHODS

Participants were 69 adolescents between 12 and 16 years old who engaged in a multidisciplinary obesity treatment centre (either outpatient or inpatient) in two countries (Belgium and France). To assess the attrition rates, frequency distributions were used. To test the predictors of attrition, zero-inflated negative binomial regression was performed.

RESULTS

Attrition rates were high, in the outpatient group, more than half of the participants (53.3%) used the app for only 0-7 days. In the inpatient group, this percentage was 24.1%. Only deficits in initiating (a component of executive functions) were a negative predictor of attrition, indicating that deficits in initiating lead to lower attrition rates.

CONCLUSIONS

This study provides evidence for high attrition rates in mHealth interventions for adolescents with obesity and was the first to investigate psychological predictors of attrition to an mHealth monitoring tool in adolescents with obesity in treatment. Findings regarding predictors of attrition should be approached with caution due to the small sample size.

Heart Rate Variability Assessment of Land Navigation and Load Carriage Activities in Specialist Police Selection

Police tactical group (PTG) personnel are exposed to physical, mental, and emotional stressors. Consequently, PTG selection courses (SCs) impart similar challenges, often resulting in candidate attrition. Holistic assessment may provide additional support to stakeholders given these risks. Heart Rate Variability (HRV) is an objective holistic stress measure that may be applicable in PTG SCs but has not been thoroughly researched. Therefore, this study aimed to report HRV data in an end-user accessible format and determine the relationship between HRV and attrition. A total of 18 qualified Australian State law enforcement officers completed a 1-day physical readiness assessment. Of those, six males progressed to an additional two-day course, on which this study is focused. This two-day selection consisted of additional physical challenges and occupational assessments. HRV was obtained from 2-lead ECGs and defined as the percentage of R-R intervals that varied by ≥50 ms (pRR50). Data were summarized in a heat map of consecutive short-term analyses. Three candidates withdrew. A logistic regression based on heat map data found high HRV was significant for predicting attrition, χ2 (6) = 8.318, p = 0.004. HRV may provide insight for PTG stakeholders monitoring attrition. While the sample size was limited and replication is needed, this study tentatively establishes value for HRV monitoring in PTG SCs.

Mobile and Web-Based Partnered Intervention to Improve Remote Access to Pain and Posttraumatic Stress Disorder Symptom Management: Recruitment and Attrition in a Randomized Controlled Trial

BACKGROUND

Increasing access to nonpharmacological interventions to manage pain and posttraumatic stress disorder (PTSD) is essential for veterans. Complementary and integrative health (CIH) interventions can help individuals manage symptom burden with enhanced accessibility via remotely delivered health care. Mission Reconnect (MR) is a partnered, self-directed intervention that remotely teaches CIH skills.

OBJECTIVE

The purpose of this paper is to describe the recruitment, onboarding phase, and attrition of a fully remote randomized controlled trial (RCT) assessing the efficacy of a self-directed mobile and web-based intervention for veterans with comorbid chronic pain and PTSD and their partners.

METHODS

A total of 364 veteran-partner dyads were recruited to participate in a mixed methods multisite waitlist control RCT. Qualitative attrition interviews were conducted with 10 veterans with chronic pain and PTSD, and their self-elected partners (eg, spouse) who consented but did not begin the program.

RESULTS

At the point of completing onboarding and being randomized to the 2 treatment arms, of the 364 recruited dyads, 97 (26.6%) failed to complete onboarding activities. Reported reasons for failure to complete onboarding include loss of self-elected partner buy-in (n=8, 8%), difficulties with using remote data collection methods and interventions (n=30, 31%), and adverse health experiences unrelated to study activities (n=23, 24%). Enrolled veterans presented at baseline with significant PTSD symptom burden and moderate-to-severe pain severity, and represented a geographically and demographically diverse population. Attrition interviews (n=10) indicated that misunderstanding MR including the intent of the intervention or mistaking the surveys as the actual intervention was a reason for not completing the MR registration process. Another barrier to MR registration was that interviewees described the mailed study information and registration packets as too confusing and excessive. Competing personal circumstances including health concerns that required attention interfered with MR registration. Common reasons for attrition following successful MR registration included partner withdrawal, adverse health issues, and technological challenges relating to the MR and electronic data collection platform (Qualtrics). Participant recommendations for reducing attrition included switching to digital forms to reduce participant burden and increasing human interaction throughout the registration and baseline data collection processes.

CONCLUSIONS

Challenges, solutions, and lessons learned for study recruitment and intervention delivery inform best practices of delivering remote self-directed CIH interventions when addressing the unique needs of this medically complex population. Successful recruitment and enrollment of veterans with chronic pain and PTSD, and their partners, to remote CIH programs and research studies requires future examination of demographic and symptom-associated access barriers. Accommodating the unique needs of this medically complex population is essential for improving the effectiveness of CIH programs. Disseminating lessons learned and improving access to remotely delivered research studies and CIH programs is paramount in the post-COVID-19 climate.

Risk factors of tooth wear in permanent dentition: A scoping review

BACKGROUND

Tooth wear (TW) prevalence is high and increasing and has important consequences on the patient's quality of life. Knowledge of risk factors is crucial to promote diagnosis, prevention strategies and timely interceptive treatment. Many studies have identified TW risk factors.

OBJECTIVE

This scoping review aims to map and describe suspected available factors associated with TW in permanent dentition based on quantitative measurement.

METHODS

The scoping review was conducted using the PRISMA extension of the Scoping Reviews checklist. The search was conducted in October 2022 from the Medline® (PubMed® interface) and Scopus® databases. Two independent reviewers selected and characterised the studies.

RESULTS

2702 articles were identified for assessment of titles and abstracts, and 273 articles were included in the review. The results show a need to standardise TW measurement indices and the study design. The included studies highlighted various factors, classified into nine domains: sociodemographic factors, medical history, drinking habits, eating habits, oral hygiene habits, dental factors, bruxism and temporomandibular disorders, behavioural factors, and stress. Results related to chemical TW (erosion) risk factors underline the importance of eating disorders, gastroesophageal reflux and lifestyle, particularly drinking and eating behaviours, which supports developing public health information campaigns and interventions. Besides chemical, this review identifies evidence of several mechanical TW risk factors, such as toothbrushing and bruxism; the influence of this last factor needs to be further explored.

CONCLUSIONS

TW management and prevention require a multidisciplinary approach. Dentists are in the first line to detect associated diseases such as reflux or eating disorders. Consequently, practitioners' information and guideline diffusion should be promoted, and a TW risk factors checklist (the ToWeR checklist) is proposed to help diagnostic approaches.

Predictors of treatment attrition of cognitive health interventions in first episode psychosis

AIM

Dropping out of psychological interventions is estimated to occur in up to a third of individuals with psychosis. Given the high degree of attrition in this population, identifying predictors of attrition is important to develop strategies to retain individuals in treatment. We observed a particularly high degree of attrition (48%) in a recent randomized controlled study assessing cognitive health interventions for first-episode psychosis participants with comorbid social anxiety. Due to the importance of developing interventions for social anxiety in first episode psychosis, the aim of the present study was to identify putative predictors of attrition through a secondary analysis of data.

METHODS

Participants (n = 96) with first episode psychosis and comorbid social anxiety were randomized to receive cognitive behavioural therapy for social anxiety or cognitive remediation. Differences between completers and non-completers (<50% intervention completed) were compared using t-tests or chi-square analyses; statistically significant variables were entered into a multivariate logistic regression model.

RESULTS

Non-completers tended to be younger, had fewer years of education and had lower levels of social anxiety compared to completers. Lower baseline social anxiety and younger age were statistically significant predictors of non-completion in the logistic regression model.

CONCLUSIONS

Age and social anxiety were predictors of attrition in cognitive health interventions in first episode psychosis populations with comorbid social anxiety. In the ongoing development of social anxiety interventions for this population, future studies should investigate specific engagement strategies, intervention formats and outcome monitoring to improve participant retention in treatment.

Attrition from paediatric weight management impacts anthropometric outcomes at 2 years, but not health-related quality of life

The study objective is to evaluate the influence of attrition from a paediatric weight management program (PWM) on health indicators over a 2-year period. In this observational study, children and youth with obesity were recruited at entry into a family-based behaviour modification PWM and had four research study visits, independent of clinic visits, over 2 years. Participants were divided into attrition groups based on length of clinic enrolment. Body composition, cardiometabolic health and health-related quality of life (HRQoL) were assessed. Among 269 children enrolled, 19% had no clinic treatment visit, 16% had treatment visits only up to 6 months, 23% up to 1 year and 42% had at least one clinic visit after 1 year (No Attrition). Greater declines in BMI z-score and body fat were seen at 2 years in children with No Attrition, while improvements in HRQoL were similar for all attrition groups. Children who attended at least one treatment visit reported improved HRQoL up to 2 years, regardless of duration in clinic. In contrast, declines in body fat and BMI z-score were greater at 2 years for those with at least one visit after 1 year. Continued efforts to reduce attrition are likely to improve anthropometric health outcomes during PWM.

Determinants of completion and early dropout in an adult weight management service: a prospective observational study

BACKGROUND

High attrition rates in weight management interventions (WMIs) undermine their effectiveness but are poorly understood. This study aimed to identify determinants of completion and early dropout in National Health Service (NHS) WMIs.

METHODS

In this prospective observational study, 329 patients recruited at initial consultation appointments satisfied the eligibility criteria: age ≥18 years and body mass index (BMI) ≥30 kg/m2 . Multivariate logistic regression analyses were performed to identify the odds ratios (OR, given with 95% confidence interval) of completion and early dropout.

RESULTS

Intervention completion rate was 39.8% (131 of 329). Variables that increased the likelihood of completion included engagement in support sessions, OR10.6 (4.7-23.6, p < 0.001); male sex, OR2.5 (1.4-4.5, p = 0.002); osteoarthritis, OR1.9 (1.1-3.3, p = 0.014); and one or more missed intervention appointments marked as 'could not attend' (notified nonattendance), OR1.8 (1.1-2.9, p = 0.032). Odds of early dropout were higher for participants with anxiety and depression OR2.0 (1.0-4.0, p = 0.039). Dietetic 1:1 participants were less likely to drop out early compared with group programme participants, OR0.3 (0.2-0.7, p = 0.002), but were less likely to complete the full intervention, OR0.5 (0.3-0.9, p = 0.02). Age, BMI, social deprivation and travel distance were among the variables not associated with completion or early dropout.

CONCLUSIONS

This study provides further evidence of the importance of support for participants of WMIs and the need for services to consider how support networks can be incorporated. Patients with poorer mental health may be more likely to drop out early and consequently benefit less from WMIs. Future research should qualitatively explore why these factors contribute to attrition to improve WMI effectiveness.

Recruitment and Retention Strategies Used in Dietary Randomized Controlled Interventions with Cancer Survivors: A Systematic Review

BACKGROUND

The purpose of this review was to systematically evaluate the quality of reporting of recruitment and retention methods in diet-related intervention trials among cancer survivors.

METHODS

A systematic search of five databases in Spring 2023 identified dietary intervention randomized controlled trials with a minimum of 50 cancer survivors, an intervention of at least eight weeks, and at least six months of study duration. Outcomes investigated include methodologic description and reporting of recruitment and retention rates.

RESULTS

Seventeen trials met inclusion criteria. Recruitment methods included cancer registry and clinician referral, hospital records, flyers, and media campaigns, and were reported in 88.2% of studies. Eleven of 17 studies (64.7%) met a priori recruitment goals. Eleven studies identified an a priori retention goal and seven met the goal. Retention goals were met more often for studies of less than one year (71.4%) versus greater than one year (50%), and for studies with remote or hybrid delivery (66.7%) versus only in-person delivery (50%).

CONCLUSIONS

Recruitment goals and methods are frequently reported; reporting of retention methods and goals is limited. Efforts are needed to improve reporting of retention methods and rates to inform best practices and enhance the rigor of future dietary intervention trials.

Understanding Attrition in Text-Based Health Promotion for Fathers: Survival Analysis

BACKGROUND

Web-based interventions targeting parents with health and parenting support frequently report high rates of attrition. The SMS4dads text messaging program, developed in Australia, has delivered texts to over 10,000 fathers. The brief text messages, which are sent 3 times per week from 16 weeks of gestation to 48 weeks after birth, include regular reminders that participants can leave the program by texting back "STOP" to any message. Although acceptance of the program is high, almost 1 in 5 ask it to be removed. Analyzing the factors influencing attrition from digital parenting programs such as SMS4dads may assist in developing more effective interventions.

OBJECTIVE

This study aimed to examine factors associated with attrition in a text-based intervention targeting fathers.

METHODS

Demographic characteristics, requests to complete a psychological scale, individual message content, participant feedback, and automatically collected data registering clicks on links embedded in the texts were examined to identify attrition factors among 3261 participants enrolled in SMS4dads from 4 local health districts in New South Wales, Australia, between September 2020 and December 2021.

RESULTS

Participants who were smokers, recorded risky alcohol consumption, had a lower education level, or signed up prenatally had 30% to 47% higher hazard of dropout from the program, whereas participant age, Aboriginal or Torres Strait Islander status, rurality, and psychological distress score (as Kessler Psychological Distress Scale [K10] category) were not associated with dropout. Primary reasons for dropping out reported by 202 of 605 respondents included "other reasons" (83/202, 41.1%), followed by "not helpful" (47/202, 23.3%) and "too busy" (44/202, 21.8%). Program features such as repeated requests to complete a psychological scale (K10) and the content of individual messages were not linked to increased dropout rates. Analysis of a sample (216/2612) of inactive participants who had not engaged (clicked on any embedded links) for at least 10 weeks but who had not opted out identified a further 1.5% of participants who would opt to leave the program if asked.

CONCLUSIONS

Identifying which features of the participant population and of the program are linked to dropout rates can provide guidance for improving program adherence. However, with limited information from feedback surveys of those exiting early, knowing which features to target does not, by itself, suggest ways to increase engagement. Planning ahead to include robust measures of attrition, including more detailed feedback from participants, could provide more effective guidance. A novel element in this study was seeking feedback from inactive participants to estimate dropout from this group and thereby provide an overall dropout rate of 20%. The retention rate of 80%, relatively high compared with other web-based parenting programs for fathers, suggests that tailoring the content to specifically address fathers' role may be an important consideration in reducing fathers' disengagement.

Proportion of Attrition and Associated Factors Among Children Receiving Antiretroviral Therapy in Public Health Facilities, Southern Ethiopia

Purpose

Acquired immunodeficiency syndrome (AIDS) is a major global public health concern. Despite the improved access and utilization of antiretroviral therapy (ART), attrition from care among children continues to be a major obstacle to the effectiveness of ART programs. Hence, this study aimed to assess the proportion of attrition and associated factors among children receiving ART in public health facilities of Gamo and South Omo Zones, Southern Ethiopia.

Patients and Methods

A retrospective follow-up study was conducted in public health facilities of Gamo and South Omo Zones in Southern Ethiopia from April 12, 2022, to May 10, 2022. The proportion of attrition was determined by dividing the number of attrition by the total number of participants. Descriptive statistics were calculated. A binary logistic regression model was used to identify factors associated with attrition. Statistical significance was set at p-value <0.05.

Results

The median age of the participants was 5.5 (IQR: 2-9) years. The proportion of attrition from ART care was 32.4% (95% confidence interval (CI): 27.57% to 37.69%). Death of either of the parents (adjusted odds ratio (AOR) = 2.19; 95% CI:1.14, 4.18), or both parents (AOR = 3.19; 95% CI: 1.20, 8.52), hemoglobin level <10mg/dL (AOR = 2.39, 95% CI: 1.21, 4.70), a cluster of differentiation (CD)4 count ≤200 cells/mm3 (AOR = 6.78, 95% CI: 3.16, 14.53), CD4 count 200-350 cells/mm3 (AOR = 2.65, 95% CI: 1.16, 6.03), suboptimal adherence (AOR = 6.38; 95% CI: 3.36, 12.19), and unchanged initial regimen (AOR = 6.88; 95% CI: 3.58, 13.19) were factors associated with attrition.

Conclusion

Attrition from care is identified to be a substantial public health problem. Therefore, designing interventions to improve the timely tracing of missed follow-up schedules and adherence support is needed, especially for children with either/both parents died, unchanged initial regimen, low CD4, and/or low hemoglobin level.

Undertreatment in patients with advanced urothelial cancer: systematic literature review and meta-analysis

Aim: To assess rates of no systemic treatment (NST), attrition across lines of therapy, and factors influencing treatment selection in patients with locally advanced or metastatic urothelial cancer (la/mUC). Methods: Systematic literature review to identify real-world studies reporting NST or attrition rates in la/mUC from 2017-2022 (including data reported since 2015). Results: Of 2439 publications screened, 29 reported NST rates, ranging from 40-74% in eight European-based studies, 14-60% in 12 US-based studies, and 9-63% in nine studies in other locations (meta-analysis estimate, 39%). Factors associated with NST or no second-line therapy included older age, female sex, poor performance status, poor renal function and distant metastases. Conclusion: A substantial proportion of patients with la/mUC do not receive guideline-recommended treatment.

Examining the Effect of a Parent-to-Parent Intervention for Low-Income Youth with Serious Emotional and Behavioral Challenges

BACKGROUND

Numerous barriers to mental health utilization exist for families of children who present with serious emotional and behavioral challenges. Evidence-based practices that facilitate equitable outcomes across diverse populations are essential to identify. This study examined possible differential service outcomes in a Medicaid-funded, parent-to-parent intervention called Parent Support Partner (PSP).

METHOD

Data from four hundred and sixty-four parents who received PSP services were evaluated for possible demographic differences in service completion. Within-group analyses were utilized for an analysis of outcomes (parent change, child functioning; treatment acceptability) within a subset (N = 153) of those who completed services.

RESULTS

No racial disparities were found in those who completed PSP (43%) when compared to those who did not (57%). Regression analyses uncovered significant improvements in parent competence and confidence, as well as overall child functioning (global functioning across domains such as school, home, behaviors). Consistent with identifying evidence-based practices, findings were seen consistently across the diverse sample of those who completed PSP services. Improvements in parents' sense of competence and confidence were correlated with perceptions of treatment acceptability.

DISCUSSION

PSP is an innovative and promising intervention with demonstrated high levels of acceptability found to increase parent confidence and self-competence to advocate for treatments that can improve the mental health functioning of their child. Future investigations of factors associated with increasing PSP service completion and outcomes in larger and more diverse populations are necessary. Implications for considering and possibly adopting this evidence-informed practice within the nursing profession are provided.

Identifying factors associated with UK veterinary nurse resignations through examination of veterinary practice data

BACKGROUND

This study aimed to identify demographic, practice and job-specific factors that are associated with veterinary nurses resigning from UK companion animal veterinary practices.

METHODS

Employment data from nurses working across a group of practices at the end of 2020 were included. Nurses were categorised into those who remained at, or resigned from, their practice in 2021. Proposed risk factors for future resignations were analysed using multivariable binary logistic regression modelling.

RESULTS

In total, 278 of 1642 (16.9%) nurses across 418 practices resigned in 2021. The most frequently recorded reasons for nurses resigning included 'career progression' (n = 102; 36.7%), 'personal reasons' (n = 36; 12.9%) and 'better pay or benefits' (n = 33; 11.9%). Factors associated with lower odds of future nurse resignations included longer tenure (p < 0.001), higher practice property and facilities rating (p = 0.049) and being a head or student nurse (p = 0.008).

LIMITATIONS

Data were collected retrospectively and were not recorded for research purposes.

CONCLUSIONS

This study highlights key factors that are predictive of veterinary nurse resignations. With known difficulties in staff retention within veterinary practices, analysis of these data is an important addition to the evidence base surrounding the complex issue of nurse retention and could help steer future retention strategies.

Retention and Predictors of Attrition Among People Living With HIV on Antiretroviral Therapy in Guinea: A 13-Year Historical Cohort Study in Nine Large-Volume Sites

Objectives: The objective of this study was to estimate the retention rate of patients in an ART program and identify the predictors of attrition. Methods: This was a historical cohort study of HIV patients who started ART between September 2007 and April 2020, and were followed up on for at least 6 months in nine large-volume sites. Kaplan Meier techniques were used to estimate cumulative retention and attrition probabilities. Cox proportional hazards models were used to identify predictors of attrition. Results: The cumulative probability of retention at 12 and 24 months was 76.2% and 70.2%, respectively. The attrition rate after a median follow-up time of 3.1 years was 35.2%, or an incidence of 11.4 per 100 person-years. Having initiated ART between 2012 and 2015; unmarried status; having initiated ART with CD4 count <100 cells/μL; and having initiated ART at an advanced clinical stage were factors significantly associated with attrition. Conclusion: The retention rate in our study is much lower than the proposed national target (90%). Studies to understand the reasons for loss to follow-up are needed.

Advanced HIV disease and associated attrition after re-engagement in HIV care in Myanmar from 2003 to 2019: a retrospective cohort study

BACKGROUND

The burden of advanced HIV disease (AHD) and predictors of outcomes among people living with HIV (PLHIV) re-engaging in care are not well known.

METHODS

We conducted a retrospective cohort study of PLHIV who re-engaged in care after being lost to follow-up (LFU), from 2003 to 2019, in Myanmar. We calculated the incidence rates of attrition after re-engagement and performed Cox regression to identify risk factors for attrition.

RESULTS

Of 44 131 PLHIV who started antiretroviral treatment, 12 338 (28.0%) were LFU at least once: 7608 (61.6%) re-engaged in care, 4672 (61.4%) with AHD at re-engagement. The death and LFU rates were 2.21-fold (95% CI 1.82 to 2.67) and 1.46-fold (95% CI 1.33 to 1.61) higher among patients who re-engaged with AHD (p>0.001). Death in patients who re-engaged with AHD was associated with male sex (adjusted HR [aHR] 2.63; 95% CI 1.31 to 5.26; p=0.006), TB coinfection (aHR 2.26; 95% CI 1.23 to 4.14; p=0.008) and sex work (aHR 7.49, 95% CI 2.29 to 22.52; p<0.001). History of intravenous drug use was identified as a predictor of being LFU.

CONCLUSIONS

Re-engagement in HIV care in Myanmar is frequent and those who re-engage carry a high burden of AHD. As AHD at re-engagement is associated with higher attrition rates, implementation of differentiated interventions that enable earlier linkage to care and prompt identification and management of AHD in this population is necessary.
