Association of Very Low Birth Weight Infants With Parental and Sibling Mental Health Care Usage.

BACKGROUND AND OBJECTIVES: Parents and siblings of very low birth weight, premature infants are at risk for poor mental health outcomes with increased mental health care usage. Knowledge regarding mental health care use patterns could guide interventions. METHODS: This retrospective cohort study included US families with commercial insurance coverage from a single carrier. Neonates born at ≤30 weeks' gestational age or with a birth weight <1500 g were identified by insurance claim data between July 1, 2015, and June 30, 2016. Each case neonate family was matched with up to 4 control families. RESULTS: The study included 1209 case and 1884 control neonates (with 134 deaths among only the case neonates [11.1% of cases]); 2003 case and 3336 control parents (mean [SD] age, 34.6 [5.4] years; 2858 [53.5%] female); and 884 case and 1878 control siblings (mean [SD] age, 6.8 [5.5] years; 1375 [49.8%] female). Compared with controls, more case parents used mental health care over the first year after birth hospitalization discharge. Higher usage was observed for bereaved case parents soon after their child's death. A smaller proportion of bereaved case siblings received mental health care compared with controls. Although nonbereaved case parents returned toward the proportion of use observed in controls, nonbereaved case female siblings, bereaved case female and male siblings, and bereaved male parents experienced continued differences. CONCLUSIONS: Understanding and meeting the mental health care needs of parents and siblings of very low birth weight premature neonates can be guided by these findings, including elevated and prolonged needs of bereaved parents and siblings.

Goals of Care Among Parents of Children Receiving Palliative Care.

Importance: While knowing the goals of care (GOCs) for children receiving pediatric palliative care (PPC) are crucial for guiding the care they receive, how parents prioritize these goals and how their priorities may change over time is not known. Objective: To determine parental prioritization of GOCs and patterns of change over time for parents of children receiving palliative care. Design, Setting, and Participants: A Pediatric Palliative Care Research Network's Shared Data and Research cohort study with data collected at 0, 2, 6, 12, 18, and 24 months in hospital, outpatient, or home settings from April 10, 2017, to February 15, 2022, at 7 PPC programs based at children's hospitals across the US. Participants included parents of patients, birth to 30 years of age, who received PPC services. Exposures: Analyses were adjusted for demographic characteristics, number of complex chronic conditions, and time enrolled in PPC. Main Outcomes: Parents' importance scores, as measured using a discrete choice experiment, of 5 preselected GOCs: seeking quality of life (QOL), health, comfort, disease modification, or life extension. Importance scores for the 5 GOCs summed to 100. Results: A total of 680 parents of 603 patients reported on GOCs. Median patient age was 4.4 (IQR, 0.8-13.2) years and 320 patients were male (53.1%). At baseline, parents scored QOL as the most important goal (mean score, 31.5 [SD, 8.4]), followed by health (26.3 [SD, 7.5]), comfort (22.4 [SD, 11.7]), disease modification (10.9 [SD, 9.2]), and life extension (8.9 [SD, 9.9]). Importantly, parents varied substantially in their baseline scores for each goal (IQRs more than 9.4), but across patients in different complex chronic conditions categories, the mean scores varied only slightly (means differ 8.7 or less). For each additional study month since PPC initiation, QOL was scored higher by 0.06 (95% CI, 0.04-0.08) and comfort scored higher by 0.3 (95% CI, 0-0.06), while the importance score for life extension decreased by 0.07 (95% CI, 0.04-0.09) and disease modification by 0.02 (95% CI, 0-0.04); health scores did not significantly differ from PPC initiation. Conclusions and Relevance: Parents of children receiving PPC placed the highest value on QOL, but with considerable individual-level variation and substantial change over time. These findings emphasize the importance of reassessing GOCs with parents to guide appropriate clinical intervention.

Surgical Intervention in Patients Receiving Pediatric Palliative Care Services.

BACKGROUND AND OBJECTIVES: Many patients receiving pediatric palliative care (PPC) present with surgically treatable problems. The role of surgery in the care of these patients, however, has not yet been defined. We conducted a cohort study of children receiving PPC to assess the incidence, type, and likely purpose of surgical interventions performed after the initiation of PPC. METHODS: We performed a cohort analysis of surgical interventions performed on children enrolled in an ongoing, multicenter, prospective cohort study. Patients aged <30 years receiving PPC services were eligible for inclusion in the study. Analyses included descriptive and comparative statistics, as well as logistic regression models. RESULTS: After initiation of PPC, 81.1% (n = 488) of patients had undergone at least 1 surgical intervention (range, 1-71) with a median of 4 interventions (interquartile range, 1-9). The most frequent surgical interventions were feeding tubes, endoscopic biopsy, tracheostomy, bone marrow biopsy, tunneled catheters, bronchoscopy, and chest tube placement, followed by sternum closure, abdominal closure, atrial and ventricular septal defect repairs, and heart transplantation. Children who underwent surgical interventions were statistically less likely to die while receiving PPC (29% vs 40%, P < .03). CONCLUSIONS: Most children receiving PPC services undergo at least 1 surgical intervention, and many undergo numerous interventions. Undergoing intervention is not futile because surgical intervention is associated with longer survival. Various patient populations that are more likely, as well as less likely, to undergo surgical intervention warrant specific focus.

Hospital-level variation in genetic testing in children's hospitals' neonatal intensive care units from 2016 to 2021.

PURPOSE: This study aimed to examine variation in genetic testing between neonatal intensive care units (NICUs) across hospitals over time. METHODS: We performed a multicenter large-scale retrospective cohort study using NICU discharge data from the Pediatric Hospital Information System database between 2016 and 2021. We analyzed the variation in the percentage of NICU patients who had any genetic testing across hospitals and over time. We used a multivariable multilevel logistic regression model to investigate the potential association between patient characteristics and genetic testing. RESULTS: The final analysis included 207,228 neonates from 38 hospitals. Overall, 13% of patients had at least 1 genetic test sent, although this varied from 4% to 50% across hospitals. Over the study period, the proportion of patients tested increased, with the increase disproportionately borne by hospitals already testing high proportions of patients. On average, patients who received genetic testing had higher illness severity. Controlling for severity, however, only minimally reduced the degree of hospital-level variation in genetic testing. CONCLUSION: The percentage of NICU patients who undergo genetic testing varies among hospitals and increasingly so over time. Variation is largely unexplained by differences in severity between hospitals. The degree of variation suggests that clearer guidelines for NICU genetic testing are warranted.

The Design of a Data Management System for a Multicenter Palliative Care Cohort Study.

CONTEXT: Prospective cohort studies of individuals with serious illness and their family members, such as children receiving palliative care and their parents, pose challenges regarding data management. OBJECTIVE: To describe the design and lessons learned regarding the data management system for the Pediatric Palliative Care Research Network's Shared Data and Research (SHARE) project, a multicenter prospective cohort study of children receiving pediatric palliative care (PPC) and their parents, and to describe important attributes of this system, with specific considerations for the design of future studies. METHODS: The SHARE study consists of 643 PPC patients and up to two of their parents who enrolled from April 2017 to December 2020 at seven children's hospitals across the United States. Data regarding demographics, patient symptoms, goals of care, and other characteristics were collected directly from parents or patients at 6 timepoints over a 24-month follow-up period and stored electronically in a centralized location. Using medical record numbers, primary collected data was linked to administrative hospitalization data containing diagnostic and procedure codes and other data elements. Important attributes of the data infrastructure include linkage of primary and administrative data; centralized availability of multilingual questionnaires; electronic data collection and storage system; time-stamping of instrument completion; and a separate but connected study administrative database used to track enrollment. CONCLUSIONS: Investigators planning future multicenter prospective cohort studies can consider attributes of the data infrastructure we describe when designing their data management system.

Pediatric Palliative Care Parents' Distress, Financial Difficulty, and Child Symptoms.

CONTEXT: Parents of patients with a serious illness experience psychological distress, which impacts parents' wellbeing and, potentially, their ability to care for their children. Parent psychological distress may be influenced by children's symptom burden and by families' financial difficulty. OBJECTIVES: This study examined the associations among parent psychological distress, parent-reported patient symptoms, and financial difficulty, seeking to determine the relative association of financial difficulty and of patient symptoms to parent psychological distress. METHODS: Cross-sectional study of baseline data for 601 parents of 532 pediatric palliative care patients enrolled in a prospective cohort study conducted at seven US children's hospitals. Data included self-reported parent psychological distress and parent report of child's symptoms and family financial difficulty. We used ordinary least squares multiple regressions to examine the association between psychological distress and symptom score, between psychological distress and financial difficulty, and whether the degree of financial difficulty modified the relationship between psychological distress and symptom score. RESULTS: The majority of parents were moderately to severely distressed (69%) or severely distressed (17%) and experienced some degree of financial difficulty (65%). While children's symptom scores and family financial difficulty together explained more of the variance in parental psychological distress than either variable alone, parental distress was associated more strongly, and to a larger degree, with financial difficulty than with symptom scores alone. CONCLUSIONS: Parent psychological distress was associated with parent-reported patient symptoms and financial difficulty. Future work should examine these relationships longitudinally, and whether interventions to improve symptom management and ameliorate financial difficulties improve parental outcomes.

Association Between Children With Life-Threatening Conditions and Their Parents' and Siblings' Mental and Physical Health.

Importance: Despite concerns regarding the potential deleterious physical and mental health outcomes among family members of a child with a life-threatening condition (LTC), few studies have examined empirical measures of health outcomes among these family members. Objectives: To examine whether mothers, fathers, sisters, and brothers of children with 1 of 4 types of pediatric LTCs have higher rates of health care encounters, diagnoses, and prescriptions compared with families of children without these conditions. Design, Setting, and Participants: This retrospective cohort study included US families with commercial insurance coverage from a single carrier. Children who had 1 of 4 LTCs (substantial prematurity, critical congenital heart disease, cancer, or a condition resulting in severe neurologic impairment) were identified by a diagnosis in their insurance claim data between July 1, 2015, and June 30, 2016. Each case child and their family was matched with up to 4 control children and their families based on the age of the case and control children. Data were analyzed between August 2020 and March 2021. Exposures: Having a child or sibling with substantial prematurity, critical congenital heart disease, cancer, or a condition resulting in severe and progressive neurologic impairment. Main Outcomes: Rates of occurrence of health care encounters, physical and mental health diagnoses, and physical and mental health medication prescriptions, identified from insurance claims data, were compared between case and control families using a multivariable negative binomial regression model. The statistical analysis adjusted for observed differences between case and control families and accounted for clustering at the family level. Results: The study included 25 528 children (6909 case children [27.1%] and 18 619 control children [72.9%]; median age, 6.0 years [IQR, 1-13 years]; 13 294 [52.1%] male), 43 357 parents (11 586 case parents [26.7%] and 31 771 control parents [73.3%]; mean [SD] age, 40.4 [8.1] years; 22 318 [51.5%] female), and 25 706 siblings (7664 case siblings [29.8%] and 18 042 control siblings [70.2%]; mean [SD] age, 12.1 [6.5] years; 13 114 [51.0%] male). Overall, case mothers had higher rates of the composite outcome of health care encounters, diagnoses, and prescriptions compared with control mothers (incident rate ratio [IRR], 1.61; 95% CI, 1.54-1.68), as did case fathers compared with control fathers (IRR, 1.55; 95% CI, 1.46-1.64). Sisters of children with LTCs had higher rates of the composite outcome compared with sisters of children without LTCs (IRR, 1.68; 95% CI, 1.55-1.82), as did brothers of children with LTCs compared with brothers of children without LTCs (IRR, 1.70; 95% CI, 1.56-1.85). Conclusions and Relevance: In this cohort study, mothers, fathers, sisters, and brothers who had a child or sibling with 1 of 4 types of LTCs had higher rates of health care encounters, diagnoses, and medication prescriptions compared with families who did not have a child with that condition. The findings suggest that family members of children with LTCs may experience poorer mental and physical health outcomes. Interventions for parents and siblings of children with LTCs that aim to safeguard their mental and physical well-being appear to be warranted.

An Interprofessional Team-Based Intervention to Address Barriers to Initiating Palliative Care in Pediatric Oncology: A Multiple-Method Evaluation of Feasibility, Acceptability, and Impact.

CONTEXT: Many children with advanced cancer are not referred to palliative care despite both professional recommendations to do so and bereaved parental preference for earlier support from sub-specialty palliative care. OBJECTIVES: To assess the feasibility, acceptability, and impact of an adaptive intervention to address individual and team-level barriers to specialty palliative care referrals. METHODS: A multiple-method approach assessed feasibility and acceptability among clinicians from pediatric oncology teams at a single institution. Quantitative measures of comfort with palliative care consultations, team cohesion, and team collaboration were conducted before and after the intervention. Number of palliative care consults were examined before, during, and after sessions. Intervention satisfaction surveys and qualitative interviews were conducted after the intervention. RESULTS: Twenty-six team members (90% of consented) attended at least one intervention session with 20 (69%) participants completing 75% or more sessions. The intervention was modified in response to participant feedback. After the intervention, participants reported greater team cohesion, comfort discussing palliative care consultation, team collaboration, process satisfaction, and decision satisfaction. Participants agreed that the training was useful, effective, helpful, and worthwhile, that they would use the skills, and that they would recommend the training to other providers. The numbers of palliative care consults increased before intervention sessions were conducted, but did not significantly change during or after the sessions. In the interviews, participants reported overall favorably regarding the intervention with some participants reporting changes in practice. CONCLUSION: An adaptive intervention to reduce barriers to initiating palliative care for pediatric oncology teams is feasible and acceptable.

Pharmacokinetic Profile of Spectrum Reduced Nicotine Cigarettes.

INTRODUCTION: Spectrum research cigarettes have been developed with varying nicotine content for use in studies evaluating the effects of a regulatory policy reducing the permissible nicotine content in cigarettes. This study aimed to characterize the nicotine pharmacokinetic profile of Spectrum cigarettes. METHODS: Twelve daily smokers attended four sessions and had blood nicotine, exhaled carbon monoxide, and subjective effects measured before and after smoking either a single cigarette of their preferred brand or high (10.9 mg/cigarette), medium (3.2 mg/cigarette), or low (0.2 mg/cigarette) nicotine content Spectrum research cigarettes, in a double-blind design with order counterbalanced. RESULTS: The boost in blood nicotine concentration was dose-dependent, with a boost of 0.3, 3.9, and 17.3 ng/mL for low-, medium-, and high-nicotine content Spectrum cigarettes. The high dose Spectrum had a similar nicotine boost to the "preferred brand" cigarettes (19 ng/mL). Subjects took longer puffs on the low nicotine cigarettes, but smoked these cigarettes faster than other cigarette types. High nicotine Spectrum cigarettes reduced the urge to smoke more than other cigarette types. CONCLUSIONS: This study shows that Spectrum research cigarettes produce blood nicotine absorption in a dose-dependent manner, and therefore, are appropriate for use in studies of nicotine reduction in cigarettes. IMPLICATIONS: This is the first study to determine the pharmacokinetic profile of Spectrum reduced nicotine content research cigarettes following an overnight abstinence. These data could provide evidence to regulatory agencies about the effects of reduced nicotine cigarettes when considering regulations on tobacco reduction.

Time to first cigarette of the day and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) in adult regular and non-daily smokers: (NHANES) 2007-10.

As the number of regular smokers has decreased over the last decade, the prevalence of light (<10 cigarettes per day) and non-daily smokers has increased. As the FDA continues to develop regulations for tobacco products, understanding factors related to toxin exposure in all smokers is essential. The present study evaluated the relation between the tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), as measured by its metabolite, and patterns of heavy smoking (>10 cigarettes per day), light smoking and non-daily smoking and the time to the first cigarette of the day (TTFC), a robust predictor of nicotine addiction, cessation failure, sleep disruption and other health indicators. Findings from a sample of 352 smokers suggest that among intermittent, non-daily and light daily smokers, TTFC of the day was associated with higher levels of NNK metabolite, an effect which was mediated by urinary cotinine levels, but not by the number of cigarettes smoked per day. This suggests these groups of smokers may be puffing each cigarette more intensely, thus increasing nicotine and toxin exposure, despite fewer overall cigarettes. These findings provide further information regarding toxicant exposure associated with lower-frequency smoking and has implications for future regulatory research approaches with lowered nicotine cigarettes and other tobacco products.

Bidirectional, Daily Temporal Associations between Sleep and Physical Activity in Adolescents.

This study evaluated the daily, temporal associations between sleep and daytime physical activity and sedentary behavior among adolescents from the Fragile Families & Child Wellbeing Study. A sub-sample of the cohort at age 15 (N = 417) wore actigraphy monitors for one week during the school year from which we derived daily minutes in sedentary and moderate-to-vigorous physical activity (MVPA) and nighttime sleep measures. Multilevel models tested temporal associations of nightly sleep onset, offset, duration, and sleep maintenance efficiency, with daily MVPA and sedentary behavior. More MVPA than an individual's average was associated with earlier sleep onset (p < 0.0001), longer duration (p = 0.03), and higher sleep maintenance efficiency (p < 0.0001). On days with more sedentary behavior than an individual's average, sleep onset and offset were delayed (p < 0.0001), duration was shorter (p < 0.0001), and sleep maintenance efficiency was higher (p = 0.0005). Conversely, nights with earlier sleep onset predicted more next-day sedentary behavior (p < 0.0001), and nights with later sleep offset and longer sleep duration were associated with less MVPA (p < 0.0001) and less sedentary time (p < 0.0001, p = 0.004) the next day. These bidirectional associations between sleep and physical activity suggest that promoting MVPA may help to elicit earlier bedtimes, lengthen sleep duration, and increase sleep efficiency, critical for healthy adolescent development.

Time to First Cigarette, Physical Activity, and Pulmonary Function in Middle-aged to Older Adult Smokers.

BACKGROUND: How addiction severity relates to physical activity (PA), and if PA moderates the relation between PA and lung function among smokers, is unknown. This study explored the independent and interactive associations of nicotine addiction severity and PA with lung function. METHODS: The study used cross-sectional data from 343 adult smokers aged 40 to 79 participating in the 2009-10 and 2011-12 National Health and Nutrition Examination Survey. Assessed were the independent relations of nicotine addiction severity, as measured by the time to first cigarette (TTFC), and average daily minutes of moderate and vigorous PA with lung function ratio (FEV1/FVC). Additional analysis examined whether PA moderated the relationship between addiction severity and lung function. RESULTS: Greater lung function was independently associated with moderate PA and later TTFC, but not vigorous PA, when controlling for cigarettes per day (CPD), past month smoking, ethnicity, years smoked, and gender (P-values < .05). PA did not moderate the association between addiction severity (TTFC) and lung function (P = .441). CONCLUSION: Among middle-aged to older smokers, increased PA and lower addiction severity were associated with greater lung function, independent of CPD. This may inform research into the protective role of PA and identification of risk factors for interventions.
