Predicting Who Receives Nonpharmacologic Pain Interventions in the Pediatric Intensive Care Unit.

AIMS: The majority of patients in the pediatric intensive care unit (PICU) experience pain daily, while nonpharmacologic interventions are indicated for pain management in children, there is limited information on which nonpharmacologic interventions are provided in the PICU and which patients receive those interventions. The aim of this descriptive correlational secondary data analysis was to determine what nonpharmacologic interventions were recorded in the electronic health record of PICU patients and patterns in use by patient demographics. SETTING/SUBJECTS: All patients hospitalized in 15 participating PICUs are located within 12 unique children's hospitals across the United States were eligible for participation. METHODS: Nonpharmacologic interventions used in the PICU were identified and differences between patients who did and did not receive those interventions were examined using Fisher's exact test. A generalized linear mixed effects model was constructed to determine patient characteristics that predict nonpharmacologic pain intervention application. RESULTS: Of 220 enrolled patients, 97 (44%) had nonpharmacologic pain interventions recorded in their electronic health record. The most frequently recorded interventions included repositioning (65%), decreasing environmental stimuli (55%), caregiver presence (37%), distraction (23%), and music therapy (20%). Children who had moderate to severe pain were most likely to receive nonpharmacologic pain interventions. CONCLUSIONS: Nonpharmacologic pain management is applied inconsistently across PICUs and may be underdocumented or underutilized. Additional research is needed to determine when nurses use nonpharmacologic pain interventions, their rationale for applying these interventions across differing groups, and the effectiveness of these interventions in managing pain in critically ill children.

Implementing Prone Positioning for COVID-19 Patients Outside the Intensive Care Unit.

BACKGROUND: Proning intubated intensive care unit patients for the management of acute respiratory distress syndrome is an accepted standard of practice. We examined the nursing climate in 4 units and its impact on implementing a novel self-proning protocol to treat COVID-19 patients outside the intensive care unit. LOCAL PROBLEM: Nursing units previously designated for medical/surgical populations had to adjust quickly to provide evidence-based care for COVID-19 patients attempting self-proning. METHODS: Nurses from 4 nursing units were surveyed about the implementation process on the self-proning protocol. Their perception of unit implementation was assessed via the Implementation Climate Scale. INTERVENTIONS: A new self-proning nursing protocol was implemented outside the intensive care unit. RESULTS: Consistent education on the protocol, belief in the effectiveness of the intervention, and a strong unit-based climate of evidence-based practice contributed to greater implementation of the protocol. CONCLUSIONS: Implementation of a new nursing protocol is possible with strong unit-based support, even during a pandemic.

The Experience of Pain and Pain Tool Preferences of Hospitalized Youth.

BACKGROUND: An accurate holistic pediatric pain assessment is necessary for quality pain management. Evidence continues to be published indicating inadequacies in pediatric pain management. It is important for clinicians to consider the pain assessment process while caring for youth. AIM: The purpose of this study was to understand the pain experience through focused interviews and to explore how youth use, interpret and understand self-report pain assessment tools including their tool preferences. DESIGN: A qualitative descriptive study using a research developed semi-structured interview guide was conducted with 40 hospitalized youth, 10-17 years (M: 13yr; S.D. 2.4); 21 (52.5%) female on a medical inpatient unit. Interview questions focused on: current pain experience; pain related symptoms; evaluation of pain treatment and preferences for select pain assessment tools: 0-10 Numeric Rating Scale, The Oucher, Faces Pain Scale-Revised, and Adolescent Pediatric Pain Tool (APPT). SETTING: Large tertiary and quaternary care pediatric hospital located in northeastern United States. PARTICIPANTS/SUBJECTS: Hospitalized youth, 10-17 years of age. RESULTS: Analysis of transcribed interviews yielded 3 themes: My Pain Now, Pain Treatment Expectations, and Telling Healthcare Providers about My Pain. Additionally, pain tools preference, assessment frequency, and discussion of how behavior, activity level, and pain expression was different for each youth. APPT was the preferred pain assessment tool. Descriptive words such as sharp, throbbing, and aching were identified most often. Youth identified that activity and pain level often do not match. CONCLUSIONS: Because pain is multi-dimensional, assessing each dimension (quality, location, intensity, and meaning) is key to thorough assessment. Results provide insight into youth preferences influencing clinical practice such as offering options for interventions and having a voice in the pain management process. All nurses caring for children should discuss available pain tools preferably before the child is in pain and assure the child knows how to use the tool.

Pain Assessment in the Patient Unable to Self-Report: Clinical Practice Recommendations in Support of the ASPMN 2019 Position Statement.

Pain is a subjective experience, unfortunately, some patients cannot provide a self-report of pain verbally, in writing, or by other means. In patients who are unable to self-report pain, other strategies must be used to infer pain and evaluate interventions. In support of the ASPMN position statement "Pain Assessment in the Patient Unable to Self-Report", this paper provides clinical practice recommendations for five populations in which difficulty communicating pain often exists: neonates, toddlers and young children, persons with intellectual disabilities, critically ill/unconscious patients, older adults with advanced dementia, and patients at the end of life. Nurses are integral to ensuring assessment and treatment of these vulnerable populations.

ASPMN 2019 Position Statement: Pain Assessment in the Patient Unable to Self-Report.

Managing pain in those vulnerable populations who are unable to self-report or communicate is challenging due to difficulty recognizing pain presence and severity. As no valid and reliable objective measure of pain exists, the ASPMN supports assessment practice recommendations that gather relevant information to infer presence of pain and evaluate response to intervention. Nurses and other healthcare professionals must be advocates for those who are unable to speak for themselves regarding their pain experience.

Nursing Research Priorities in the Pediatric Emergency Care Applied Research Network (PECARN): Reaching Consensus Through the Delphi Method.

INTRODUCTION: Pediatric emergency nurses who are directly involved in clinical care are in key positions to identify the needs and concerns of patients and their families. The 2010 Institute of Medicine report on the future of nursing supports the active participation of nurses in the design and implementation of solutions to improve health outcomes. Although prior efforts have assessed the need for research education within the Pediatric Emergency Care Applied Research Network (PECARN), no systematic efforts have assessed nursing priorities for research in the pediatric ED setting. METHODS: The Delphi technique was used to reach consensus among emergency nurses in the PECARN network regarding research priorities for pediatric emergency care. The Delphi technique uses an iterative process by offering multiple rounds of data collection. Participants had the opportunity to provide feedback during each round of data collection with the goal of reaching consensus about clinical and workforce priorities. RESULTS: A total of 131 nurses participated in all 3 rounds of the survey. The participants represented the majority of the PECARN sites and all 4 regions of the United States. Through consensus 10 clinical and 8 workforce priorities were identified. DISCUSSION: The PECARN network provided an infrastructure to gain expert consensus from nurses on the most current priories that researchers should focus their efforts and resources. The results of the study will help inform further nursing research studies (for PECARN and otherwise) that address patient care and nursing practice issues for pediatric ED patients.

Bedside Placement of the Postpyloric Tube in Infants.

BACKGROUND: Patients in the neonatal intensive care unit are a vulnerable population with specific nutritional requirements, which include increased protein and caloric needs for adequate growth. Some infants cannot tolerate gastric feeds and need to have postpyloric feeds to grow. Placement of a postpyloric tube can be done by gastric insufflation. Gastric insufflation is a technique where air is inserted into the stomach as a nasogastric tube is advanced through the pylorus to the duodenum. There is research to support this technique in pediatrics, but scant evidence exists for placement of postpyloric tubes in the infant population. PURPOSE: The aim of this quality improvement practice project was to determine whether the current practice for postpyloric tube placement by the bedside nurses in the neonatal intensive care unit is safe and effective. METHODS: Data were prospectively collected on 38 infants requiring placement of 60 postpyloric tubes over an 8-week period. RESULTS: The results indicate a success rate of 95.6% for tube placement when a subset of infants diagnosed with congenital diaphragmatic hernia (CDH) (n = 15) was excluded. Six (40%) of the 15 infants with CDH had postpyloric tubes placed successfully. Nursing years of experience did not affect successful postpyloric tube placement. IMPLICATIONS FOR PRACTICE: The postpyloric tube placement policy was modified as a result of findings from this project. Placement of a postpyloric tube with one attempt by the bedside nurse was safe and effective in most preterm infants in our care excluding patients with CDH. The new policy reduced infants' exposure to radiation due to a decrease in the number of x-rays in comparison to interventional radiology placement. IMPLICATIONS FOR RESEARCH: Further research should be done by units that primarily care for low birth-weight premature infants.

Safety of a 1-Day Polyethylene Glycol 3350 Bowel Preparation for Colonoscopy in Children.

OBJECTIVES: Electrolyte-free polyethylene glycol powder (PEG-3350) has been widely used for colonoscopy preparation (prep); however, limited safety data on electrolyte changes exists with 1-day prep regimens. The primary aim of this study was to determine the proportion of patients with significant serum chemistry abnormalities before and at the time of colonoscopy. Secondary aims included evaluation of prep tolerance and bowel cleansing efficacy. METHODS: We performed a prospective descriptive observational study of pediatric patients scheduled for outpatient colonoscopy who received our standard 1-day, weight-based 4 g/kg PEG-3350 prep with a single stimulant laxative dose and had serum chemistry testing within 60 days before and at the time of colonoscopy. A standardized bowel cleanliness tool (Aronchick scale) was completed by the endoscopist. RESULTS: One hundred fifty-five patients had serum electrolytes data pre- and postprep. Comparison of each patient's chemistries demonstrated statistical equivalence with the 1 exception of blood urea nitrogen levels (P = 0.56). Hypokalemia was detected postprep in 37 subjects (24%), but none had a serum level <3.3 mmol/L, which was deemed to be of no clinical significance. Five patients were hypoglycemic post prep; 3 were 7 years or younger (P = 0.02). The colon cleanliness rating was excellent or good in 77% and suboptimal in 23% of patients. CONCLUSIONS: A 1-day, weight-based PEG-3350 bowel prep in children appears safe. Changes in electrolyte levels and renal function were not clinically significant. Children of 7 years or younger seem to be at a higher risk of hypoglycemia compared with older children.

Pain management following major intracranial surgery in pediatric patients: a prospective cohort study in three academic children's hospitals.

INTRODUCTION: Pain management following major intracranial surgery is often limited by a presumed lack of need and a concern that opioids will adversely affect postoperative outcome and interfere with the neurologic examination. Nevertheless, evidence in adults is accumulating that these patients suffer moderate to severe pain, and this pain is often under-treated. The purpose of this prospective, clinical observational cohort study was to assess the incidence of pain, prescribed analgesics, methods of analgesic delivery, and patient/parent satisfaction in pediatric patients undergoing cranial surgery at three major university children's hospitals. METHODS: After obtaining IRB and parental consent (and when applicable, patient assent), children who underwent cranial surgery for cancer, epilepsy, vascular malformations, and craniofacial reconstruction were studied. Neither intraoperative anesthetic management nor postoperative pain management was standardized, but were based on institutional routine. Patients were evaluated daily by a study investigator and by chart review for pain scores using age appropriate, validated tools (FLACC, Faces Pain Scale-Revised, Wong-Baker Faces Scale or Self-Report on a 0-10 scale), for patient/parent satisfaction using a subset of the NRC Picker satisfaction tool and in adolescents a modified QoR-40, and for the frequency, mode of administration, and type of analgesic provided. Finally, the incidence of opioid-induced side effects, specifically nausea, vomiting, pruritus, altered level of consciousness, and need for emergency diagnostic radiologic studies for altered neurologic examination were recorded. Data are provided as mean ± SD. RESULTS: Two hundred children (98:102 M:F), averaging 7.8 ± 5.8 years old (range 2 months-18.5 years) and 32.2 ± 23.0 kg (range 4.5-111.6 kg) undergoing craniectomy (51), craniotomy (96), and craniofacial reconstruction (53) were studied. Despite considerable variation in mode and route of analgesic administration, there were no differences in average pain score, length of hospital stay, or parental satisfaction with care. Interestingly, opioid-induced side effects were not related to total daily opioid consumption, site of surgery, or method of opioid delivery. The most common side effect was vomiting. No patient developed respiratory depression or altered mental status secondary to analgesic therapy. Regardless of age or procedure, once eating, most patients were treated with oral oxycodone and/or acetaminophen. CONCLUSIONS: Despite considerable variation in modality and route of analgesic administration, there were no differences in average pain score, length of stay, or parental satisfaction with care. Pain scores were low, side effects were minimal, and parental satisfaction was high, providing equipoise for future blinded prospective randomized trials in this patient population.

Charting the course of pediatric nursing research: the SPN Delphi study.

In order to inform the care of children at this pivotal time in the history of healthcare, the Society of Pediatric Nurses (SPN) sought to identify priorities for nursing research and key challenges facing pediatric nursing. A three round Delphi study was conducted electronically with SPN members. The top 10 priorities and challenges were identified and will serve as a valuable guide for pediatric nursing practice, education, policy and administration over the coming decade.

Polyethylene glycol powder solution versus senna for bowel preparation for colonoscopy in children.

OBJECTIVES: Safety and effectiveness of large-volume polyethylene glycol-based solution (PEG-ES) have been documented, but the taste and volume can be barriers to successful colonoscopy preparation. Efficacy and safety of small-volume electrolyte-free (PEG-P) preparation (Miralax) for colonoscopy preparation have been rarely studied, although presently used at many pediatric centers. The primary objective of the present study was to determine whether PEG-P results in a more efficacious and safe colonoscopy preparation as compared with senna. METHODS: The study design was prospective, randomized, and single-blinded. Patients ages 6 to 21 years were randomized to a 2-day clean-out regimen of PEG-P at a dose of 1.5 g/kg divided twice per day for 2 days versus senna 15 mL daily (ages 6-12) or 30 mL daily (ages 12-21) for 2 days. Both preparations required 1 day of clear liquids whereas senna preparation required an additional day of full liquid diet. A blinded endoscopist graded the quality of preparation with a standardized cleanliness tool (Aronchick scale). Serum chemistry panels were obtained. Patients or parents rated symptoms and ease of preparation. The anticipated number of subjects was 166; however, the interim analysis demonstrated inferiority of senna preparation. RESULTS: Thirty patients were evaluated in the present study. Of the patients in the PEG-P arm, 88% (14/16) received an excellent/good score compared with 29% (4/14), with the senna preparation (P = 0.0022). Both preparations were well-tolerated by patient-graded ease of preparation. Demographics and laboratory values did not differ significantly across the 2 groups. No serious adverse events were noted. CONCLUSIONS: PEG-P is an effective colonoscopy preparation whereas senna preparation was insufficient. Both were well-tolerated and appear safe in a pediatric population.

Transitioning to Independent Nursing Practice during COVID-19: A Mixed Methods Study.

The COVID-19 pandemic presented challenges to onboard and support new graduate nurses (NGNs). This study sought to explore the perceptions of nurses entering clinical practice during the COVID-19 pandemic. Using mixed methods, we investigated the experiences of NGNs entering the field during the pandemic and how a nurse residency program (NRP) adapted to meet their needs. Newly graduated nurses entering practice in November 2019 described their transition through nurse experience surveys and focus group discussions. Results from the quantitative data reported on compassion satisfaction, burnout, and exposure to secondary traumatic stress. The qualitative data mirrored these findings with the discovery of the following five themes: transitioning through an NRP, impact to nursing care, value of coworkers, coping, and professional growth. These findings illustrate the need to better support future practice transitions in times of disruption and change.

Delivering the National Diabetes Prevention Program: Assessment of Outcomes in In-Person and Virtual Organizations.

The Centers for Disease Control and Prevention's Diabetes Prevention Recognition Program (DPRP) has helped organizations deliver the National Diabetes Prevention Program (National DPP) lifestyle change program for over 10 years. Four delivery modes are now approved: in person, online (self-paced, asynchronous delivery), distance learning (remote, synchronous delivery), and combination (hybrid delivery using more than one delivery mode). We assessed outcomes using data from 333,715 participants who started the 12-month program between January 1, 2012, and December 31, 2018. The average number of sessions attended was highest for in-person participants (15.0), followed by online (12.9), distance learning (12.2), and combination (10.7). The average number of weeks in the program was highest for in-person participants (28.1), followed by distance learning (20.1), online (18.7), and combination (18.6). The average difference between the first and last reported weekly physical activity minutes reflected an increase for in person (42.0), distance learning (27.1), and combination (15.0), but a decrease for online (-19.8). Among participants retained through session 6 or longer, average weekly physical activity minutes exceeded the program goal of 150 for all delivery modes. Average weight loss (percent of body weight) was greater for in person (4.4%) and distance learning (4.7%) than for online (2.6%) or combination (2.9%). Average participant weight loss increased gradually by session for all delivery modes; among participants who remained in the program for 22 sessions, average weight loss exceeded the program goal of 5% for all delivery modes. In summary, if participants stay in the program, most have positive program outcomes regardless of delivery mode; they have some outcome improvement even if they leave early; and their outcomes improve more the longer they stay. This highlights the benefits of better retention and increased enrollment in the National DPP lifestyle change programs, as well as enhancements to online delivery.

Time changes for scheduled nursing assessments: impact on clinical decisions and patient discharge.

Using a shared governance model, a clinical nursing practice change was implemented to increase collaborative decision making among health care providers at morning rounds. The goal of this project was to improve nursing workflow at the beginning of the shift and improve patient flow by discharging patients earlier. By changing the time of morning vital signs and nursing assessments from 0800 to 0600, staff reported increased collaboration among the multidisciplinary team and improved nursing workflow.

Finding the evidence to change practice for assessing pain in children who are cognitively impaired.

We report on a quality improvement project whose purpose was to systematically review behavioral pain assessment tools for children who are cognitively impaired, with the goal of identifying a valid and reliable tool for clinical practice. In addition, we sought to partner with parents and/or caregivers to expand their role in pain assessment. The project team conducted an extensive synthesis of the literature to examine the availability and quality of published pain assessment tools for use with children with cognitive impairment (CI) or developmental disability. Once completed, we identified 2 of the available 10 tools to test in the clinical setting. Data from this quality improvement project provided evidence to support the adoption of the revised Faces, Legs, Activity, Cry, and Consolability pain assessment tool for children with CI into clinical practice.

Optimizing the assessment of pain in children who are cognitively impaired through the quality improvement process.

Pain assessment in children with cognitive impairment (CI) is challenging. A quality improvement (QI) project involving evidence-based review of pain assessment tools, feedback from the Family Advisory Council, trialing of selected tools within clinical settings including obtaining feedback from nurses, and parents caring for nonverbal children with developmental delay was reported. Synthesized evidence supported the adoption of revised Faces, Legs, Activity, Cry, and Consolability pain assessment tool into clinical practice. Results of postimplementation audit and challenges of staff nurse involvement in the QI process were also discussed. The 24-month-long QI process and its impact on changing practice were described in detail.

Delivering the National Diabetes Prevention Program: Assessment of Enrollment in In-Person and Virtual Organizations.

The aim of the US Centers for Disease Control and Prevention's (CDC) National Diabetes Prevention Program (National DPP) is to make an evidence-based lifestyle change program widely available to the more than 88 million American adults at risk for developing type 2 diabetes. The National DPP allows for program delivery using four delivery modes: in person, online, distance learning, and combination. The objective of this study was to analyze cumulative enrollment in the National DPP by delivery mode. We included all participants who enrolled in CDC-recognized organizations delivering the lifestyle change program between January 1, 2012, and December 31, 2019, and whose data were submitted to CDC's Diabetes Prevention Recognition Program. During this time, the number of participants who enrolled was 455,954. Enrollment, by delivery mode, was 166,691 for in-person; 269,004 for online; 4,786 for distance-learning; and 15,473 for combination. In-person organizations enrolled the lowest proportion of men (19.4%) and the highest proportions of non-Hispanic Black/African American (16.1%) and older (65+ years) participants (28.2%). Online organizations enrolled the highest proportions of men (27.1%), younger (18-44 years) participants (41.5%), and non-Hispanic White participants (70.3%). Distance-learning organizations enrolled the lowest proportion of Hispanic/Latino participants (9.0%). Combination organizations enrolled the highest proportions of Hispanic/Latino participants (37.3%) and participants who had obesity (84.1%). Most in-person participants enrolled in organizations classified as community-centered entities (41.4%) or medical providers (31.2%). Online and distance-learning participants were primarily enrolled (93.3% and 70.2%, respectively) in organizations classified as for-profit businesses or insurers. Participants in combination programs were enrolled almost exclusively in organizations classified as medical providers (89%). The National DPP has reached nearly half a million participants since its inception in 2012, but continued expansion is critical to stem the tide of type 2 diabetes among the many Americans at high risk.

The Association of the Nurse Work Environment and Patient Safety in Pediatric Acute Care.

OBJECTIVES: Eighteen years ago, the Institute of Medicine estimated that medical errors in hospital were a major cause of mortality. Since that time, reducing patient harm and improving the culture of patient safety have been national health care priorities. The study objectives were to describe the current state of patient safety in pediatric acute care settings and to assess whether modifiable features of organizations are associated with better safety culture. METHODS: An observational cross-sectional study used 2015-2016 survey data on 177 hospitals in four U.S. states, including pediatric care in general hospitals and freestanding children's hospitals. Pediatric registered nurses providing direct patient care assessed hospital safety and the clinical work environment. Safety was measured by items from the Agency for Healthcare Research and Quality's Culture of Patient Safety survey. Hospital clinical work environment was measured by the National Quality Forum-endorsed Practice Environment Scale. RESULTS: A total of 1875 pediatric nurses provided an assessment of safety in their hospitals. Sixty percent of pediatric nurses gave their hospitals less than an excellent grade on patient safety; significant variation across hospitals was observed. In the average hospital, 46% of nurses report that mistakes are held against them and 28% do not feel safe questioning authority regarding unsafe practices. Hospitals with better clinical work environments received better patient safety grades. CONCLUSIONS: The culture of patient safety varies across U.S. hospital pediatric settings. In better clinical work environments, nurses report more positive safety culture and higher safety grades.

The Pediatric American Pain Society Patient Outcomes Questionnaire (Pediatric APS-POQ): Development and Initial Psychometric Evaluation of a Brief and Comprehensive Measure of Pain and Pain Outcomes in Hospitalized Youth.

Pediatric pain assessment in the hospital traditionally involves the patient's self-report of pain intensity using a numeric rating scale, which does not capture the complexity of the pain experience. No valid, comprehensive measure of pain in hospitalized youth exists. This study was designed to develop and conduct initial psychometric testing of the Pediatric American Pain Society Patient Outcomes Questionnaire (Pediatric APS-POQ), a comprehensive patient-reported measure of pain and pain outcomes in hospitalized youth. A multidisciplinary group of pediatric pain researchers and clinicians collaborated to adapt the adult APS-POQ Revised to pediatrics, including a patient-report and parent proxy version. The adapted measures were administered to 218 pediatric inpatients (age M = 13.4 years, 56% female) and 214 of their parents (80% mothers) at 4 US children's hospitals. The measure was feasible to administer within the inpatient setting and was acceptable and understandable to pediatric patients and their parents. Internal consistency was adequate for both patient-report and parent proxy (α = 0.77). Confirmatory factor analysis supported the following 6 domains, consistent with the adult measure: pain intensity, functional interference, emotional response, side effects, perceptions of care, and usual pain. Additional research is needed to further support the reliability and validity of this measure in diverse clinical populations. PERSPECTIVE: To reduce the impact of pain on hospitalized youth, pediatric pain assessment must move beyond ratings of pain intensity. The Pediatric APS-POQ provides a brief but comprehensive assessment of pain and pain outcomes in hospitalized children and adolescents, which will allow for greater individualization in hospital-based pain management and quality improvement purposes.

Retention Among Participants in the National Diabetes Prevention Program Lifestyle Change Program, 2012-2017.

OBJECTIVE: To assess retention in the National Diabetes Prevention Program (DPP) lifestyle change program, which seeks to prevent type 2 diabetes in adults at high risk. RESEARCH DESIGN AND METHODS: We analyzed retention among 41,203 individuals who enrolled in Centers for Disease Control and Prevention (CDC)-recognized in-person lifestyle change programs at organizations that submitted data to CDC's Diabetes Prevention Recognition Program during January 2012-February 2017. RESULTS: Weekly attrition rates were typically <1-2% but were between 3.5% and 5% at week 2 and at weeks 17 and 18, where session frequency typically transitions from weekly to monthly. The percentage of participants retained through 18 weeks varied by age (45.9% for 18-29 year olds, 53.4% for 30-44 year olds, 60.2% for 45-54 year olds, 66.7% for 55-64 year olds, and 67.6% for ≥65 year olds), race/ethnicity (70.5% for non-Hispanic whites, 60.5% for non-Hispanic blacks, 52.6% for Hispanics, and 50.6% for other), mean weekly percentage of body weight lost (41.0% for ≤0% lost, 66.2% for >0% to <0.25% lost, 72.9% for 0.25% to <0.5% lost, and 73.9% for ≥0.5% lost), and mean weekly physical activity minutes (12.8% for 0 min, 56.1% for >0 to <60 min, 74.8% for 60 to <150 min, and 82.8% for ≥150 min) but not by sex (63.0% for men and 63.1% for women). CONCLUSIONS: Our results demonstrate the need to identify strategies to improve retention, especially among individuals who are younger or are members of racial/ethnic minority populations and among those who report less physical activity or less early weight loss. Strategies that address retention after the first session and during the transition from weekly to monthly sessions offer the greatest opportunity for impact.
