School nurse perception of asthma care in school-based telehealth.

OBJECTIVE: School-based telehealth (SBTH) offers an opportunity to overcome traditional barriers to providing comprehensive asthma care for children. Guided by an implementation science framework considering factors internal and external to the school setting, we characterized barriers and facilitators to asthma care within an existing SBTH program available in over 50 under-resourced South Carolina schools. METHODS: This cross-sectional study assessed barriers and facilitators to SBTH asthma care delivery using web-based surveys of school nurses, specifically addressing school implementation of telehealth methods. Surveys evaluated practices and nurse and school-specific factors related to telehealth implementation including perceived barriers, organizational readiness and self-efficacy. Utilizers were schools who completed 1-10 average visits per month while non-utilizers completed less than 1 average visit per month. Descriptive statistics were performed to characterize perceptions in utilizers versus non-utilizers. RESULTS: Of 53 surveys distributed, 36 were completed (68% response rate). Commonly cited barriers included inadequate time due to competing tasks in both utilizers (65%) and non-utilizers (74%) as well as lack of caregiver involvement in care planning (94% of utilizers and 84% of non-utilizers). Of those utilizing specific, relevant telehealth services, schools scored high in perceptions of organizational readiness (n = 24, mean: 24.5/30), self-efficacy (n = 26, mean: 3.6/5) and comfort with identifying students eligible for SBTH (n = 26, mean: 3.5/5). CONCLUSIONS: We identified inadequate nurse time and challenges engaging caregivers as key barriers to implementation of a school-based telehealth asthma program providing care to an under-resourced population. Addressing these barriers when expanding telehealth services may promote utilization of telehealth.

Management of Pediatric Isolated Skull Fractures: A Decision Tree and Cost Analysis on Emergency Department Disposition Strategies.

OBJECTIVE: Pediatric isolated skull fractures (ISFs) are common injuries that represent challenging disposition decisions for clinicians. The purpose of this study is to use a decision analysis to compare the clinical and cost-effectiveness of 3 emergency department (ED)-based disposition scenarios for a pediatric patient presenting with ISF. METHODS: We conducted a cost-effectiveness analysis comparing ED disposition scenarios that included current practice, increased at-home surveillance, and observation unit utilization. Current rates of admission, deterioration after initial diagnosis, and ED return after discharge, as well as cost of observation-only status, were obtained through literature review. Cost calculations using Healthcare Cost and Utilization Project data included total ED cost, admission without complication, and admission with deterioration. RESULTS: In current practice, 76% of subjects with ISF are admitted and 2.5% of those develop persistent or new symptoms. No patient diagnosed with ISF required neurosurgical intervention. Of those discharged home from the ED, 2.8% return with a new concern with 7.4% having new findings on imaging leading to admission. Total cost per 100 patients by current practice was US $583,587. Increasing at-home surveillance by 20% resulted in a total cost saving of US $113,176 per 100 patients while increasing returns to the ED from less than 1% to 1.1%. Admitting at the current rate to an observation unit resulted in a US $205,395 cost saving per 100 patients. CONCLUSIONS: Decreased inpatient utilization through home surveillance or observation unit use reduced cost associated with pediatric ISF management without increasing clinical risk owing to the low probability of clinical deterioration after initial diagnosis.

Demographic predictors of leukotriene antagonist monotherapy among children with persistent asthma.

OBJECTIVE: To describe the children with persistent asthma receiving non-preferred controller therapy in the form of leukotriene receptor antagonist monotherapy (LTRAM). STUDY DESIGN: In this cross-sectional study, we analyzed 2007-2009 South Carolina Medicaid data of children aged 2- to 18 years with persistent asthma, defined by Healthcare Effectiveness Data and Information Set (HEDIS). Those without either LTRAM or inhaled corticosteroids (ICS) were excluded. With multivariable logistic regression modeling, we compared the outcome of LTRAM with the primary predictor of age and adjusted for covariates of race, sex, HEDIS class, rurality, and disease severity. We also used negative binomial regression to compare outcomes of albuterol and oral steroid claims, outpatient and emergency department visits, and hospitalizations with predictors of LTRAM vs ICS therapy. RESULTS: A total of 19,512 patients with asthma aged 2- to 18-years were studied: 2658 (13.6%) without controllers were excluded, 2508 (12.9%) received LTRAM, and 14 346 (73.5%) received ICS. Age, race, rurality, and HEDIS classification were all significantly associated with LTRAM (all P < .01): 5- to 13-year-olds relative to children <5 years old (OR 1.46, 95% CI 1.30-1.64), Caucasians relative to African Americans (OR 1.40, 95% CI 1.27-1.53), and rural children relative to urban (OR 1.18, 95% CI 1.08-1.3) were all more likely to receive LTRAM. Albuterol, oral steroid, and outpatient visits were lower in LTRAM (P < .01). No difference was detected in emergency department visits or admissions. CONCLUSIONS: Children 5- to 13-years of age, rural children, and Caucasian children were more likely to receive LTRAM. Uncovering provider rationale and practices as well as patient influences on this prescribing pattern may be helpful in optimizing asthma controller therapy.

Persistent Opioid Use Following Pediatric Nonfatal Firearm Injury.

OBJECTIVE: Firearms are a major cause of pediatric injury. An analysis of opioid use following pediatric firearm injury has not previously been reported. Our objective was to determine the prevalence and factors associated with persistent opioid use among pediatric nonfatal firearm injury victims. METHODS: We performed a retrospective cohort study using 2015-18 claims data from the Merative MarketScan Multi-State Medicaid and Commercial Databases, utilizing International Classification of Diseases, Tenth Revision codes for firearm injury and National Drug Codes for opioids. Dispensed opioid claims were used as a proxy for opioid use. Opioid exposure was defined both dichotomously and continuously (by the total number of opioid days prescribed) in the 30 days following discharge from firearm injury index encounter. Persistent opioid use was defined as ≥1 opioid claim(s) in the 90 to 270 days following index encounter. Multivariable logistic regression analysis was performed to determine whether covariates of interest were associated with greater odds of persistent opioid use. RESULTS: Our cohort consisted of 2110 children who experienced nonfatal firearm injury (mean age 13.5, 80.9% male, 79.5% Medicaid) with 608 children (28.8%) exposed to opioids. Of patients exposed to opioids, 10.4% developed persistent opioid use. In adjusted analyses, each opioid day dispensed during the exposure period represented 5% greater odds of experiencing persistent opioid use. CONCLUSIONS: Clinicians caring for children injured by firearms should be aware of the risk of developing persistent opioid use and balance that risk with the need to sufficiently control pain.

Health Care Utilization After Nonfatal Firearm Injuries.

OBJECTIVES: Despite the high incidence of firearm injuries, little is known about health care utilization after nonfatal childhood firearm injuries. This study aimed to describe health care utilization and costs after a nonfatal firearm injury among Medicaid and commercially insured youth using a propensity score matched analysis. METHODS: We conducted a propensity score matched cohort analysis using 2015 to 2018 Medicaid and Commercial Marketscan data comparing utilization in the 12-months post firearm injury for youth aged 0 to 17. We matched youth with a nonfatal firearm injury 1:1 to comparison noninjured youth on demographic and preindex variables. Outcomes included inpatient hospitalizations, emergency department (ED) visits, and outpatient visits as well as health care costs. Following propensity score matching, regression models estimated relative risks of the health care utilization outcomes, adjusting for demographic and clinical covariates. RESULTS: We identified 2110 youth with nonfatal firearm injury. Compared with matched noninjured youth, firearm injured youth had a 5.31-fold increased risk of inpatient hospitalization (95% confidence interval [CI] 3.93-7.20), 1.49-fold increased risk of ED visit (95% CI 1.37-1.62), and 1.06-fold increased risk of outpatient visit (95% CI 1.03-1.10) 12-months postinjury. Adjusted 12-month postindex costs were $7581 (95% CI $7581-$8092) for injured youth compared with $1990 (95% CI $1862-2127) for comparison noninjured youth. CONCLUSIONS: Youth who suffer nonfatal firearm injury have a significantly increased risk of hospitalizations, ED visits, outpatient visits, and costs in the 12 months after injury when compared with matched youth. Applied to the 11 258 US youth with nonfatal firearm injuries in 2020, estimates represent potential population health care savings of $62.9 million.

Firearm Safety Screening in the Pediatric Hospital Setting: A Quality Improvement Initiative.

Background: Firearm injuries are a leading cause of morbidity and mortality for US youth. Secure storage is protective against firearm injuries in children. Despite this evidence and national recommendations, rates of firearm safety screening among pediatric providers are low, particularly in the inpatient setting. Therefore, we aimed to increase the frequency of firearm safety screening among patients admitted to the Pediatric Hospital Medicine service. Methods: This project occurred in a tertiary pediatric hospital with a medium-sized pediatric residency program. The initial intervention was a firearm safety screening tool embedded into the electronic health record history and physical note template. Subsequent interventions included nursing education, monthly reminder emails, and gun violence discussions during intern orientation. Patients who screened positive were provided with educational materials and a free gun lock. Data collection occurred by chart review to determine the frequency of screening documentation in the H&P. A survey was also conducted among pediatric residents to identify persistent barriers to screening. Results: The percentage of inpatient firearm safety screening increased from 0.01% to 39% over 25 months, with a centerline shift noted after 2 months. Residents cited a lack of time with the patient and a belief that it was not the appropriate time to screen as persistent barriers to screening. Conclusions: This study identified an effective approach to improving firearm safety screening in an academic pediatric hospital. Hospitalization represents a unique opportunity for firearm safety screening and counseling, and inpatient providers should feel empowered to intervene in this setting.

Access to Firearms: Initiation of Firearm Screening Among Psychiatric Patients in a Pediatric Emergency Department.

OBJECTIVE: Increase provider screening rates for firearm access among patients presenting to the pediatric emergency department (PED) for a psychiatric chief complaint. METHODS: In this resident-driven quality improvement project, a retrospective chart review examined firearm access screening rates among patients presenting to the PED with the chief complaint of "psychiatric evaluation." After establishing our baseline screening rate, the first phase of our plan, do, study, act (PDSA) cycle included implementing Be SMART education for pediatric residents. We made Be SMART handouts available in the PED, created electronic medical record (EMR) templates to facilitate documentation, and emailed routine reminders to residents during their PED block. In the second PDSA cycle, the pediatric emergency medicine (PEM) fellows expanded our efforts to increase project awareness from a supervisory role. RESULTS: The baseline screening rate was 14.7% (50 of 340). After PDSA 1, a center line shift occurred, and screening rates increased to 34.3% (297 of 867). After PDSA 2, screening rates increased to 35.7% (226 of 632). In the intervention phase, providers who received training screened 39.5% (238 of 603) of encounters versus providers who did not receive training screened 30.8% (276 of 896) of encounters. Of all encounters screened, 39.2% (205 of 523) screened positive for in-home firearms. CONCLUSIONS: We improved firearm access screening rates in the PED using provider education, EMR prompts, and PEM fellow participation. Opportunities remain to promote firearm access screening and secure storage counseling in the PED.

Mental Health Care Utilization Among Children and Adolescents With a Firearm Injury.

Importance: Firearm injuries are a leading cause of morbidity and mortality among US children and adolescents. Despite evidence demonstrating mental health sequelae for children and adolescents who have experienced a firearm injury, little is known about mental health care utilization after a firearm injury. Objective: To evaluate mental health care utilization in the 12 months after a firearm injury among Medicaid-insured and commercially insured children and adolescents compared with propensity score-matched controls. Design, Setting, and Participants: This propensity score-matched retrospective cohort analysis assessed 2127 children and adolescents, aged 0 to 17 years, with a firearm injury that occurred between January 1, 2016, and December 31, 2017, compared with 2127 matched controls using MarketScan Medicaid and commercial claims data. Claims data were analyzed 12 months before and after injury, with the total study period spanning from January 1, 2015, to December 31, 2018. Exposure: Nonfatal firearm injury. Main Outcomes and Measures: The primary outcome of interest was a dichotomous variable representing any mental health care utilization in the 12 months after injury. Secondary outcomes included psychotherapy utilization, substance use-related utilization, and a psychotropic medication prescription. Logistic regression modeling was used to estimate relative risks with adjusted analyses of dichotomous outcomes. Results: The overall cohort consisted of 4254 children and adolescents, of whom 2127 (mean [SD] age, 13.5 [4.1] years; 1722 [81.0%] male) had an initial encounter for a firearm injury and an equal number of matched controls (mean [SD] age, 13.5 [4.1] years; 1720 [80.9%] male). Children and adolescents with a firearm injury had a 1.40 times greater risk (95% CI, 1.25-1.56; P < .001) of utilizing mental health services in the 12 months after their injury compared with children and adolescents without a firearm injury, after controlling for potential confounders. Children and adolescents with a firearm injury had a 1.23 times greater risk (95% CI, 1.06-1.43; P = .007) of utilizing psychotherapy and a 1.40 times greater risk (95% CI, 1.19-1.64; P < .001) of substance use-related utilization. Among those who experienced a firearm injury, Black children and adolescents were 1.64 times more likely (95% CI, 1.23-2.19; P < .001) to utilize mental health care compared with White children and adolescents. Conclusions and Relevance: This propensity score-matched cohort study found that children and adolescents with a firearm injury had a greater risk of utilizing mental health services in the 12 months after their injury compared with those without an injury, and significant racial disparities were associated with use of mental health services. The findings suggest that health care practitioners should be aware of this increased risk and ensure adequate mental health follow-up for these patients.

The cost of Medicaid savings: the potential detrimental public health impact of neonatal circumcision defunding.

OBJECTIVE: To project the increased incidence of HIV and subsequent costs resulting from the expected decreased rate of circumcision due to Medicaid defunding in one southeastern state. METHODS: Using 2009 South Carolina (SC) Medicaid birth cohort (n = 29, 316), we calculated expected heterosexually acquired HIV cases at current circumcision rates. To calculate age/race/gender specific HIV incidence rates, we used 2009 South Carolina Department of Health and Environmental Control reported gender and race specific HIV cases, CDC reported age distribution of HIV cases, and 2009 S.C. population data. Accounting for current circumcision rates, we calculated the change in incidence of heterosexually acquired HIV assuming circumcision provides 60% protection against HIV transmission to males and 46% protection against male to female transmission. Published lifetime cost of HIV was used to calculate the cost of additional HIV cases. RESULTS: Assuming Medicaid circumcision rates decrease from current nationally reported levels to zero secondary to defunding, we project an additional 55 male cases of HIV and 47 female cases of HIV among this birth cohort. The total cost discounted to time of infection of these additional HIV cases is $20,924,400 for male cases and $17,711,400 for female cases. The cost to circumcise males in this birth cohort at currently reported rates is $4,856,000. CONCLUSIONS: For every year of decreased circumcision rates due to Medicaid defunding, we project over 100 additional HIV cases and $30,000,000 in net medical costs.

Pediatric Firearm Injury Mortality Epidemiology.

Firearm injury is a leading and preventable cause of death for youth in the United States. The Centers for Disease Control and Prevention web-based injury statistics query and reporting system was queried to examine changes in firearm injury mortality among youth aged 0 to 19 from 2001 to 2019. This includes assessment of overall mortality rates, mortality rates based on intent and race/ethnicity, and the proportion of deaths due to homicide, suicide, and unintentional shootings among different age groups. Regression analysis was used to identify significant differences in mortality rate over time between Black and White youth. Deaths due to firearm injury were compared with deaths due to motor vehicle traffic collisions. In 2019, firearm injuries surpassed motor vehicle collisions to become the leading cause of death for youth aged 0 to 19 years in the United States. Homicide is the most common intent across all age groups, but suicide represents a large proportion of firearm deaths in 10- to 19-year-old youth. In 2019, Black youth had a firearm mortality rate 4.3 times higher than that of White youth and a firearm homicide rate over 14 times higher than that of White youth. For each additional year after 2013, the mortality rate for Black youth increased by 0.55 deaths per 100 000 compared with White youth (time by race interaction effect P < .0001). These data indicate the growing burden of firearm injuries on child mortality and widening racial inequities with Black youth disproportionately affected by firearm violence. This public health crisis demands physician advocacy to reduce these preventable deaths among youth.

Increase in Mental Health Diagnoses Among Youth With Nonfatal Firearm Injuries.

BACKGROUND AND OBJECTIVES: Firearm injury is a leading cause of mortality for US youth. For every youth who dies from a firearm injury, at least 4 more survive. Little is known about the mental health consequences of non-fatal firearm injury in youth. Our objective was to quantify new mental health diagnoses after nonfatal firearm injury. METHODS: MarketScan Medicaid and commercial data were used to identify youth age 0 to 17 years with an initial encounter for a nonfatal firearm injury in 2016 to 2017. The International Classification of Diseases, Tenth Revision codes determined the presence of mental health conditions in the 12 months preinjury, during the index encounter, and in the 12 months postinjury. Logistic regression analysis was performed to determine factors associated with new mental health diagnoses during the 12 months postinjury. RESULTS: About 2178 patients (1769 Medicaid, 409 commercial) were identified for inclusion. 844 (38.8%) patients had a mental health diagnosis identified during the 12-month preinjury period. During the index encounter, 184 (8.5%) patients had a newly diagnosed mental health disorder. In the 12 months postinjury, 559 (25.7%) patients had a newly diagnosed mental health disorder. The most common new diagnosis categories were trauma disorders, substance abuse, and disruptive disorders. Medicaid insurance and a prior complex chronic condition were predictors of new mental health diagnosis. CONCLUSION: Over a quarter of youth with nonfatal firearm injury were diagnosed with a new mental health condition in the 12 months after their injury. Health care providers should be vigilant about mental health screening and ensuring access to mental health care services in this population.

Facilitators and Barriers to Implementation of School-Based Telehealth Asthma Care: Program Champion Perspectives.

OBJECTIVE: Asthma is one of the most common chronic conditions of childhood, conferring an immense burden on children and their caregivers. School-based telehealth approaches for asthma care provide the opportunity to deliver convenient, cost-effective care to more children in the school setting. Our study objective was to characterize school-based telehealth asthma program delivery experiences and examine barriers and facilitators to telehealth program implementation. METHODS: Interviews were conducted with telehealth program staff and school stakeholders in nine schools engaged in a school-based telehealth asthma program. A structured interview guide was designed using the Exploration, Adoption/Preparation, Implementation, Sustainment (EPIS) framework. A template analysis qualitative approach was used to identify themes related to implementation processes. RESULTS: Interviews identified key telehealth implementation strategies including building relationships, marketing and provision of technical assistance, education and support to aid program delivery. Key facilitators to successful program implementation included strong partnerships between the telehealth and school teams, a shared commitment to enhancing access to asthma care for children, and strong nurse leadership. Primary barriers to implementation included lack of family/caregiver involvement and competing demands for nurses. CONCLUSIONS: This study identified barriers and facilitators to implementing a school-based telehealth asthma program that can be used to guide education, training and support strategies to enhance program delivery. Recommended implementation strategies include building strong program-school partnerships, creating a shared vision to improve access to care, and building engagement in families and communities while supporting nurse leaders and family involvement with training and resources. These results can help guide future telehealth interventions.

Engagement and Leadership in Firearm-Related Violence Prevention: The Role of the Pediatric Hospitalist.

Gun violence is a US public health crisis. Approximately 7000 children are hospitalized each year because of firearm-related injuries. As pediatric hospitalists, we are poised to address this crisis, whether we care directly for patients who are victims of gun violence. In this article, we aim to provide practical tools and opportunities for pediatric hospitalists to address the epidemic of gun safety and gun violence prevention, including specifics related to the inpatient setting. We provide a framework to act within 4 domains: clinical care, advocacy, education and research.

Physician Use of Electronic Health Records: Survey Study Assessing Factors Associated With Provider Reported Satisfaction and Perceived Patient Impact.

BACKGROUND: The effect electronic health record (EHR) implementation has on physician satisfaction and patient care remains unclear. A better understanding of physician perceptions of EHRs and factors that influence those perceptions is needed to improve the physician and patient experience when using EHRs. OBJECTIVE: The objective of this study was to determine provider and clinical practice factors associated with physician EHR satisfaction and perception of patient impact. METHODS: We surveyed a random sample of physicians, including residents and fellows, at a US quaternary care academic hospital from February to March 2016. The survey assessed provider demographics, clinical practice factors (ie, attending, fellow, or resident), and overall EHR experience. The primary outcomes assessed were provider satisfaction and provider perceptions of impact to patient care. Responses on the satisfaction and patient impact questions were recorded on a continuous scale initially anchored at neutral (scale range 0 to 100: 0 defined as "extremely negatively" and 100 as "extremely positively"). Independent variables assessed included demographic and clinical practice factors, including perceived efficiency in using the EHR. One-way analysis of variance or the Kruskal-Wallis test was used for bivariate comparisons, and linear regression was used for multivariable modeling. RESULTS: Of 157 physicians, 111 (70.7%) completed the survey; 51.4% (57/111) of the respondents were attending physicians, and of those, 71.9% (41/57) reported a >50% clinical full-time-equivalency and half reported supervising residents >50% of the time. A total of 50.5% (56/111) of the respondents were primary care practitioners, previous EHR experience was evenly distributed, and 12.6% (14/111) of the total sample were EHR super-users. Responses to how our current EHR affects satisfaction were rated above the neutral survey anchor point (mean 58 [SD 22]), as were their perceptions as to how the EHR impacts the patient (mean 61 [SD 18]). In bivariate comparisons, only physician age, clinical role (resident, fellow, or attending), and perceived efficiency were associated with EHR satisfaction. In the linear regression models, physicians with higher reported perceived efficiency reported higher overall satisfaction and patient impact after controlling for other variables in the model. CONCLUSIONS: Physician satisfaction with EHRs and their perception of its impact on clinical care were generally positive, but physician characteristics, greater age, and attending level were associated with worse EHR satisfaction. Perceived efficiency is the factor most associated with physician satisfaction with EHRs when controlling for other factors. Understanding physician perceptions of EHRs may allow targeting of technology resources to ensure efficiency and satisfaction with EHR system use during clinical care.

Enhancing Postdischarge Asthma Care by Using Pharmacy Claims and Telephone Follow-up.

BACKGROUND AND OBJECTIVES: Asthma is a common reason for hospital readmission. The majority of children are not receiving adequate preventive care after discharge. Our objective is to decrease return visits to the emergency department (ED) or hospital for asthma through a series of interventions (eg, access to real-time claims data and structured follow-up phone calls) designed to increase preventive care. METHODS: We performed a single-site quality improvement project for children 2 to 17 years old discharged with asthma from January 2010 to March 2014. We compared a baseline period and a stepwise intervention period including the following: brief follow-up phone calls to families, access to medication claims data, and structured phone calls. The primary outcome of return visits to the ED or hospital and preventive care outcomes (controller refills and ambulatory visits) up to 90 days were assessed using state all-payer and Medicaid data sets. Interrupted time series analysis was used to investigate secular trends. RESULTS: Six hundred and seventy-seven asthma discharges were analyzed. The majority of children were 2 to 7 years old, African American, and insured by Medicaid. Successful phone contact occurred in 57% of encounters. Ninety-day revisits to the ED or hospital demonstrated a significant decline (15% to 8%; P < .05), but preventive care measures did not improve. CONCLUSIONS: A process to improve transitions for children who are hospitalized with an asthma exacerbation that includes follow-up phone calls was associated with a decrease in ED or hospital revisits. The lack of a detectable increase in preventive care warrants further exploration.

The Pipeline From Abstract Presentation to Publication in Pediatric Hospital Medicine.

BACKGROUND: The annual Pediatric Hospital Medicine (PHM) conference serves as a venue for the dissemination of research in this rapidly growing discipline. A measure of research validity is subsequent publication in peer-reviewed journals. OBJECTIVE: To identify the publication rate of abstracts submitted to the 2014 PHM conference and determine whether presentation format was associated with subsequent journal publication or time to publication. METHODS: We identified abstracts submitted to the 2014 PHM conference. Presentation formats included rejected abstracts and poster and oral presentations. Abstracts subsequently published in journals were identified by searching the author and abstract title in PubMed, MedEdPORTAL, and Google Scholar. We used logistic regression and Cox proportional hazards models to determine if presentation format was associated with publication, time to publication, and publishing journal impact factor. RESULTS: Of 226 submitted abstracts, 19.0% were rejected, 68.0% were selected for posters, and 12.8% were selected for oral presentations; 36.3% were subsequently published within 30 months after the conference. Abstracts accepted for oral presentation had more than 7-fold greater odds of publication (adjusted odds ratio 7.8; 95% confidence interval [CI], 2.6-23.5) and a 4-fold greater likelihood of publication at each month (adjusted hazard ratio 4.5; 95% CI, 2.1-9.7) compared with rejected abstracts. Median journal impact factor was significantly higher for oral presentations than other presentation formats (P < 0.01). CONCLUSIONS: Abstract reviewers may be able to identify methodologically sound studies for presentation; however, the low overall publication rate may indicate that presented results are preliminary or signify a need for increased mentorship and resources for research development in PHM.
