Clinical Trial Summary
Social determinants of health affect patients throughout the life course. They may be
particularly relevant for pediatric emergency department (ED) patients. Computerized
screening for social and behavioral determinants of health has been deemed effective and
acceptable. This pilot study will characterize the cumulative burden of health related social
problems experienced by patients and families in a pediatric ED. It will specifically examine
those patients with a subset of 9 high-risk chief complaints, patients with obesity, patients
with poor asthma control, and patients with a high number of non-urgent visits, who may be at
particularly high risk for health related social problems. Our analysis will compare these
subsets of patients with the general ED population, hypothesizing that these groups will have
a higher number of health related social problems than the general ED population. Parent and
adolescent participants will be approached during ED visits and administered a computerized
screening tool. For patients aged 0-13, a survey administered to parents will test for
thirteen distinct health related social problems. Two surveys will be administered to
adolescent-parent dyads. The adolescent survey will test for thirteen health related social
problems, seven of which overlap with those on the parent survey. The average total number of
health related social problems in patient groups hypothesized to be at high risk will be
compared to the average total number of HRSPs in the general ED population. For adolescent
patients, an intervention group will receive social navigation consisting of rapid referrals
to community resources based on survey responses by a community health liaison. Their ED
recidivism, community resource use and number of unmet social needs at 12-month follow up
will be compared with that of a control group that receives screening and written resources
only.
Description:
Significant advances have been made in pediatrics in the United States in the last 60 years.
Mortality from infectious disease and cancer, for instance, has declined significantly. The
more stubborn issues in pediatrics include poor asthma control, obesity, suicide and
adolescent homicide. To address these, our profession must begin to systematically address
social determinants of health. Scourges such as poverty, unemployment, and domestic violence
are known contributors to pediatric morbidity, adverse childhood experiences, and poor adult
health and achievement. - The emergency department (ED) may be a strategic venue in which to
identify patients at high risk for multiple social issues. We suspect that certain ED patient
characteristics may be indicative of those families at highest risk and that comprehensive
screening for social determinants of health may be the means by which they can be identified
and targeted for intervention.
Social issues in EDs are often addressed individually instead of comprehensively, if done at
all. There have been no studies of comprehensive screening for social determinants of health
in large, urban, full service pediatric EDs. In addition, no study has attempted to identify
those groups of ED patients at highest risk for a large number of social risk factors who
might benefit most from rapid interventions. The immediate objective of this proposal is to
identify groups of patients at high risk for a large number of social risk factors in a
patient-centric manner in a busy pediatric ED, using a single computerized instrument to
administer a comprehensive screen and to provide social navigation services to adolescent
patients. We will sequentially approach caregivers of patients 0-17 years of age and patients
13-21 years of age to complete surveys regarding social risk factors. The outcomes of
interest are 1) the total social risk score and 2) ED recidivism, total social risk score and
community resource use in adolescent patients who receive social navigation services vs.
enhanced usual care.
We hypothesize that patients with the following ED characteristics will have a higher social
risk score than other ED patients: patients with any of nine "high risk" chief complaints
(alleged physical abuse , alleged sexual abuse , peer assault , mammalian bites, adolescent
reproductive and sexual health issues, intoxication/substance abuse , ingestion/poisoning ,
psychiatric/behavioral complaints , any complaint with the lowest estimated severity index );
a body mass index in the obese range; frequent non-urgent visits to the ED; or poor asthma
control. Further, we hypothesize that adolescents who receive social navigation services will
have lower ED recidivism, a lower total social risk score and increased community resource
use at 12-month follow up than adolescents who receive enhanced usual care.
SPECIFIC AIM #1: To characterize the cumulative social risk score for patients and families
in a large, urban pediatric ED Hypothesis #1: Caregivers of pediatric ED patients and
adolescent ED patients will report an increased number of social risks than patients in
primary care settings have reported in prior studies.
SPECIFIC AIM #2: To compare the cumulative social risk score in pediatric ED patients with a
subset of 9 (nine) high-risk chief complaints, frequent non-urgent visits, obesity, or poor
asthma control to the cumulative burden of social risk factors in the general pediatric ED
population Hypothesis #2: Patients who present to the ED with any of a subset of nine
high-risk chief complaints, frequent non-urgent visits, obesity or poor asthma control will
have a higher social risk score than the general pediatric ED population.
SPECIFIC AIM #3: To compare ED recidivism, total social risk score and level of community
resource use at 12-month follow up in adolescents who receive social navigation services
versus those adolescents who receive enhanced usual care.
IMPACT: It is our intent to revolutionize emergency care, cementing its place as not only a
medical safety net, but a social one as well. EDs across the country will benefit from
demonstration of a method to intervene on behalf of pediatric patients whose social problems
are as important as their medical ones, if not more so. These interventions have the
potential to decrease unnecessary ED visits and ED recidivism for chronic problems caused or
exacerbated by unmet social needs. The ultimate goal is expansion of social navigation teams
in the ED and creation of a follow up clinic to address the longer term social risk factors
faced by many of our families.
* Background and Significance: The World Health Organization defines health as "the absence
of physical, psychological and social problems". Health care, as it has traditionally been
practiced in the United States and Western Europe, has focused primarily on disease and
diagnosis. This has proved insufficient, however, at improving disparities in health among
patients of different incomes, geographic origins and ethnicities. These disparities may be
due, in part, to lack of attention to social determinants of health. Addressing social
determinants is a goal of Healthy People 2020 and has now been mandated by the Institute of
Medicine. - The pediatric age group, as studied by the life course model of human health ,
seems especially sensitive to social determinants, and these effects may persist into
adulthood. , Downstream effects of poverty, substance abuse and child maltreatment can be
seen at each stage in the life course. These issues can strongly affect cognitive
functioning, , chronic disease in adulthood - , adult mortality - and adult substance use and
mental health, , which themselves can negatively affect future educational/professional
achievement and earnings.
Children exist not in a vacuum, but in the larger context of their families and communities.
It is difficult to improve their health without addressing the well-being of their adult
caregivers and families. Given its accessibility and positioning as both an entry point to
and last resort for health care, the pediatric ED may be an ideal venue for screening and
brief interventions for social problems.
Relationships between conditions addressed in the ED and social determinants are well
established. - It is well known, for example, that unaddressed mental health issues and poor
literacy in parents of asthmatic children increase their risk of frequent ED visits and
hospitalizations. , These relationships exist for conditions and chief complaints as diverse
as peer and adolescent violence, depression, diabetes, and sexually transmitted infections,
often seen disproportionately in the ED. Prior work by Fleegler et al. has found that over
50% of patients in a primary care clinic reported two or more unaddressed health-related
social problems (HRSPs). The adult population that visits the ED is at even higher risk for
HRSPs than the general population , and it is likely that this will hold true in children as
well. - Building on previous work in our Division in extending the reach of emergency care to
include screening and secondary prevention, we propose the implementation and testing of
screening for HRSPs in the ED. We have demonstrated success using audio-assisted computer
screening with mobile touch pad technology, a screening method preferred by both patients and
providers. Our long-term goal is to identify and intervene to interrupt the deleterious
effects of HRSPs on pediatric health. The immediate objective of this proposal is to
demonstrate the ability to screen for HRSPs in a patient-centric manner in a busy ED and to
provide social navigation services to an intervention group of adolescent patients. We will
use audio-assisted computerized patient/family surveys and an innovative multidisciplinary
social navigation team to accomplish these objectives.
Preliminary Studies:
1. Screening for behavioral risk factors is acceptable to adolescents and their caregivers.
We conducted a computerized survey of 276 adolescent patients and 138 caregivers.
Respondents reported >60% acceptability of screening for risk factors such as depression
and suicidality, substance use, sexual risk behaviors, violence, and housing
instability.
2. Computerized sexual health surveys to guide clinical decision making improves testing
for sexually transmitted infections (STIs) for adolescents in the emergency department
Dr. Goyal's K23 (HD070910) developed a computerized sexual health survey (SHS) to
identify adolescents at high risk for STIs and tested whether implementation of this
tool, with results-based clinical decision support, increased STI testing rates. Through
a multi-step iterative qualitative study using a Delphi panel of key informants for
survey development and content validity, and cognitive interviews with end-users, Dr.
Goyal developed a content-valid audio computer assisted self-interview (ACASI) SHS for
the identification of adolescents at risk for STIs. This tool was understandable,
well-accepted, and rated easy to use by adolescents in the ED. Furthermore, Dr. Goyal
demonstrated that it was feasible for successful implementation into the ED workflow.
6.0 * Research Design and Methods: Include a detailed description of all procedures that will
be conducted, including those performed as part of regular care. When applicable, include the
dates for charts that will be accessed and the system used to access them.
This study will utilize two self-administered, computer-based surveys that test thirteen (13)
social domains on a survey administered to caregivers of children 0-17 and thirteen (13)
social domains on a separate survey administered to adolescents 13-21. The caregiver survey
questions parents regarding the following social domains: housing, employment, income and
benefits, safety practices, access to health care, parental depression, food security,
education, substance abuse, immigration, legal issues, intimate partner violence and
literacy. The adolescent survey questions adolescents regarding the following social domains:
housing, food security, education, safety practices, access to health care, mental health,
substance abuse, sexual practices, dating violence, immigration, legal issues, human
trafficking and literacy. The study will be conducted in the emergency departments at the
Children's National Medical Center Sheikh Zayed main campus and the Children's National
Medical Center satellite campus at United Medical Center.
Survey Instrument
The survey has been developed through adaptation of previously validated questionnaires, as
described below. Once these questionnaires have been collated and adapted for our
comprehensive screening tool, we will then pilot the survey with 5 adolescents and 5
caregivers for understanding. If revisions to the survey are required, we will re-pilot the
survey once revisions are made and repeat this process until no revisions are required.
The basis of the current survey is The Online Advocate, developed and utilized in a previous
study by Eric Fleegler et al and used with permission of the author.
The housing domain includes questions derived from the American Housing Survey. It assesses
household size, current housing status, concerns about impending eviction or foreclosure,
utilities and housing hazards. Housing hazards include leakage, problems with electricity, no
heat for > 24 hours, no toilets functional, any rodent or insect infestation, or no running
water in the home. A patient or family will automatically score positive for a housing
problem if 1) the family is homeless or living with family or friends for financial reasons
("doubled up"), 2) if there are greater than 8 family members at home, 3) if a family is
concerned about an eviction, transfer or foreclosure, 4) if utilities have been shut off for
nonpayment in the last 12 months, or 5) if there are two or more unaddressed housing hazards
in the last 12 months.
The food security domain questions are the two-item screen designed by Hager et al. and
endorsed by the American Academy of Pediatrics in its 2015 guideline Promoting Food Security
for All Children. This screen has 97% sensitivity and 83% specificity for identifying food
insecurity in a family. , A patient or family will score positive for food insecurity if they
answer both questions in the affirmative. An adolescent will also score positive for food
insecurity if they qualify for WIC and don't receive it.
The employment and income security domains use questions from the Philadelphia Survey of Work
and Family and the Behavioral Risk Factor Surveillance System. A parent will score positive
if they are 1) out of work or unable to work and not receiving disability benefits, 2) not
receiving benefits (WIC, SNAP, CSFP, TANF or Medicaid) for which they qualify according to
household income, or 3) earning less than $10,000 per year. A positive score will be reversed
if the parent is out of work because they are 1) in school or a job training program, 2) on
family or maternity leave, or 3) retired.
The safety domain includes questions about car seat use, helmet use, smoke alarms, and guns
in the home. A patient or parent will score positive if 1) they are not using a car
seat/booster seat if appropriate for age and height, 2) their child does not use a helmet
regularly, 3) there are no working smoke alarms in the home, or 4) there are guns at home.
The adolescent survey adds a question about being a witness to shootings/stabbings/murder.
The adolescent will score positive if they 1) sometimes or frequently carry weapons, 2) have
been a witness to shooting/stabbing/murder, 3) do not use helmets, or 4) if there are guns at
home.
The access to health care domain includes questions from the Behavioral Risk Factor
Surveillance System . It assesses health insurance status for both parent and child.
Additionally, it assesses availability and utilization of primary medical care (if
appropriate) for parent and child. A parent or patient will score positive if either she or
her child does not have or has not used their primary medical provider within a 5- or 2-year
time frame, respectively, or does not have medical insurance. Questions regarding asthma
control were adapted from the Asthma Control Questionnaire (ACQ) for adolescents and the
Pediatric Asthma Control and Communication Instrument for the Emergency Department (PACCI-ED)
for children under 13 and will be used to test an association between poor asthma control and
number of HRSPs.
The parental and adolescent depression questions are the PHQ-2 screen, which has been
validated against longer depression screens in adolescents and adults. , A patient or parent
will score positive if they earn a score of ≥ 3. ). If they earn a score of ≥3, the screen
will convert to the PHQ-9 screen (for adults) or the PHQ-A (for adolescents), which includes
questions regarding suicidality. If either the patient or parent has a child under 3 months
old, the depression screen will instead be a 3-question subscale of the Edinburgh Postpartum
Depression Screen (EPDS), shown to have sensitivity for postpartum depression for adults and
adolescents and tested in the pediatric emergency department ; if their score on the
3-question subscale is greater than 3, the survey will automatically branch to a question
regarding suicidality. Additional questions exist about recent deaths in the household and
bullying. They will score positive if they have had a recent death in the household, have
ever lost a parent or guardian, or if they admit to bullying or being bullied frequently (or
the parent is concerned that the child is being bullied or is bullying others).
Questions regarding parental education include highest grade completed and number of adults
in the household with fluency in English. The child's or adolescent's education is assessed
with questions regarding school attendance, failing grades, and truancy. A parent survey will
automatically score positive for education if 1) the parent did not complete high school and
has not earned a GED, 2) there are no adults in the household who can speak English fluently,
3) if their child has had more than 5 unexcused absences or days home due to suspension in
the past month, or 4) if the child has received 3 or more Ds or Fs in the last grading
period. An adolescent will automatically score positive for education if they self-report
either of the last two items in the affirmative.
The CRAFFT questions screen adolescents for problematic drug or alcohol use. The TICS
(two-item conjoint screen) questions screen parents for drug or alcohol abuse or dependence.
It was shown to have nearly 80% sensitivity for detection of problematic drug and alcohol
use. Two positive answers on either survey constitute a positive screen for potential
problematic alcohol or substance use. Parents and adolescents are also questioned regarding
household members that they think may be addicted to drugs or alcohol and will earn a point
if they answer in the affirmative. They will also screen positive if they admit to smoking
cigarettes and the patient has asthma.
Immigration issues are assessed by asking about current immigration status, whether any adult
at home is a U.S. citizen or legal resident and any recent deportations or arrests for
immigration issues. Undocumented status, no adult U.S. citizen or legal resident in the home,
no adult English speakers at home or any deportations in the last 12 months will constitute a
positive screen for immigration.
Screening for intimate partner violence is accomplished via the STaT screen. It was tested in
an urban emergency department population and has a sensitivity of approximately 96% for
intimate partner violence. Any positive response will constitute a positive screen for
intimate partner violence. Questions regarding child witnesses to domestic violence are
included to screen for possible child protection issues.
Legal issues assessed include involvement in the criminal justice system of either
parent/guardian or the child. Involvement of any parent/guardian or the child with the
criminal justice system will constitute a positive screen.
The adolescent survey will include questions regarding sexual health. An adolescent will
score positive if he/she has had 5 or more lifetime partners, has ever been pregnant or
gotten someone pregnant, has had 2 or more partners in the last 3 months, is sexually active
with opposite sex partners and is not using any reliable birth control method, or is sexually
active with any partner and not using any reliable sexually transmitted infection (STI)
prevention method. In addition, an adolescent will score positive if they have had an STI in
the last 12 months or if they have not been tested for an STI in the last 12 months (unless
not sexually active).
Low literacy by patient or parent as assessed on the initial literacy questions will earn an
extra point.
Study Participants
Caregivers of patients ages 0-17 and adolescents ages 13-21 who speak English or Spanish will
be approached for survey completion following physician evaluation. Patients will be excluded
if they are triaged at estimated severity index (ESI) Level 1 or if they are unable to
complete the survey due to developmental level, inability to speak English or Spanish,
inability to read the survey when a private area/interpreter is not available to have the
survey administered verbally, or mental status. Patients will also be excluded if they are
≥22 years of age or if they present in police custody or as wards of the state. Caregivers
will be excluded if they are unable to complete the survey due to developmental level,
inability to speak English or Spanish, inability to read the survey when a private
area/interpreter is not available to have the survey administered verbally, or mental status.
If a child presents with more than one parent or legal guardian, the researcher will ask that
only one parent complete the survey. If an adolescent presents with a parent/legal guardian
but is either unwilling or unable to complete the survey, the survey will be scored as if the
adolescent presented for care alone (i.e., in the "adolescent alone" group, maximum score 12
[twelve]). If a parent/legal guardian presents with an adolescent who is unwilling or unable
to complete the survey but the parent does consent to complete it, the survey will be scored
in the "parent alone" group (maximum score 13 (thirteen)).
Study Procedures
A convenience sample of consecutive ED patients during time blocks structured to reflect the
variability of ED arrival times will be enrolled.
Following consent but prior to survey completion, the research assistant will enter into the
survey the time of day, the patient's chief complaint and chief complaint characteristics,
age, ESI level, number of non-urgent visits to CNMC in the last 12 months, ED campus, height
and weight in a blank electronic survey identified only by the patient's study number. This
information will be accessed from the Cerner FirstNet emergency department tracking software.
The adolescent and parent surveys will be linked only by a common study number without
utilizing any other identifying information.
If not completed at triage, the research assistant will measure the patient's height using
the emergency department stadiometer and standardized technique. Patients who are unable or
unwilling to stand will have their length measured if able to lie flat.
Literacy and computer facility will be assessed with four validated screening questions
administered to the parent and/or adolescent patient prior to initiation of the body of the
survey. If the patient is deemed to have high reading and computer literacy by this
standardized assessment, the research assistant will then provide the laptop, equipped with a
privacy screen and headphones, to the family for completion of the survey. If they are deemed
to have low literacy, the patient or parent will be instructed to use the audio feature of
REDCap for each question and will be offered a touch screen laptop or iPad option, or the
research assistant will read the questions to the patient and enter the answers. If the
research assistant is required to read the questions to the parent, the survey will be
conducted in a private room. If none is available within a reasonable time frame, the patient
will be excluded from the study. If not required to read the questions to the patient, he/she
will conduct a brief tutorial, then exit the room while the survey is completed.
The research assistant will review survey answers immediately following completion. If any of
the following occur in any patient or caregiver on non-social navigation days, the procedures
described below will be carried out.
1. If the study subject indicates that they wish to speak with a social worker, the
emergency department social worker will be notified. Study recruitment will only be
carried out when an emergency department social worker is available in the ED. The
social worker will only be notified of the fact that the patient would like to speak
with them (i.e., not about specific survey answers), unless any of the contingencies
described below exist.
2. If an adult study subject indicates that he/she is suicidal, the clinician in charge of
the medical care for the adult study subject's child will be notified. The DC Mobile
Crisis Services unit of the Comprehensive Psychiatric Emergency Program will be
activated. This service is available between 9 a.m. and 1 a.m. Study recruitment will
not be carried out outside these hours.
3. If a study subject 17 years of age or under indicates that he/she is suicidal, the
clinician in charge of the medical care for that study subject will be notified. An
emergency psychiatric consult in the CNMC emergency department will be obtained.
4. If an adult study subject indicates that he/she is currently experiencing intimate
partner violence, the study subject will be asked face to face by the research assistant
if they 1) would like to speak with a social worker, 2) would like to activate police
services in the appropriate jurisdiction, 3) if they feel safe going home, and 4) if
their child has witnessed or been physically affected by intimate partner violence in
the household. The ED social worker will be notified and will initiate appropriate
procedures, including the following:
1. Police services will be activated at the patient's request.
2. If the patient does not feel safe going home, they will be referred to the nearest
24 hour shelter and a warm handoff will be done.
3. If the study subject's child has witnessed or been physically affected by intimate
partner violence, a Child Protective Services report will be made.
5. If a study subject 17 years or under indicates that they are currently experiencing
intimate partner violence, the study subject will be asked face to face (but away from
their caregiver) by the research assistant if they 1) would like to speak with a social
worker, 2) would like to activate police services in the appropriate jurisdiction, 3) if
they feel safe going home, or 4) if applicable, if their child has witnessed or been
physically affected by intimate partner violence in the household. The ED social worker
will be notified and will initiate appropriate procedures, including the following:
1. Police services will be activated at the patient's request.
2. If the patient does not feel safe going home, they will be referred to the nearest
24 hour shelter and a warm handoff will be done.
3. If the study subject's child has witnessed or been physically affected by intimate
partner violence, a Child Protective Services report will be made.
6. If in the course of conversations about any of the above items a concern for physical,
sexual or emotional abuse or neglect, or human trafficking of a person under the age of
18 is uncovered, the child's clinician and social worker will be notified and a Child
Protective Services report made.
7. If the patient screens positively for human trafficking, the patient will be questioned
privately. If there is continued concern, the National Human Trafficking Hotline will be
called.
Adolescent patients in this study will be randomized into an intervention group, which will
receive social navigation services and an enhanced usual care group, which will receive
screening, the procedures described above, and a packet of community resources. The
intervention group will have access to the services of a social navigation team. The social
navigation team will consist of trained community health liaisons (undergraduates and
graduate students in medicine, public health and social work from neighboring institutions
including George Washington University, University of Maryland, Howard University, Catholic
University, and Georgetown University), a clinician and a social worker.
The social navigation team will function as follows:
1. Once the computerized screening tool has been completed by the enrolled patient, the
results will be printed by the research assistant.
2. The research assistant will then instruct the community health intern to review the
results of the completed computerized survey.
3. The community health intern will review the results, create a plan of action, i.e.
specific referrals to community agencies and next steps needed by the caregiver and or
adolescent (e.g., documents to gather, appointments to make, etc.), following
pre-developed protocols for each risk area. Each plan will be reviewed with the social
worker prior to presentation to the family. Each family will also receive a packet of
community resources relevant to each social domain covered in the screening survey,
similar to that provided to the enhanced usual care group.
4. If emergency social concerns are uncovered, e.g., homelessness, abuse, or intimate
partner violence compromising safety, the social worker will be notified immediately and
she will proceed as per her usual practice, as above.
5. If adolescents report suicidality, abuse or high risk sexual activity, the team
clinician will, as necessary, consult psychiatry, order STI testing and prophylaxis,
order emergency contraception, notify child protective services or complete any required
medicolegal forms.
Patients in the enhanced usual care group will receive risk-tailored printed information
regarding community resources from the research assistant based on responses to the
computerized survey.
Each enrolled adolescent participant will receive phone follow up at 3, 6 and 12 months by
the community health intern. The interviewer conducting the 3-month phone follow up will
assess whether any community resources were accessed. If not accessed, reasons for non-use
will be assessed. If accessed, satisfaction with resources will be assessed. If participants
have not accessed services, the navigator will provide additional resources to the
participant to enable access by addressing identified barriers (e.g. making appointments or
helping with transportation). If the phone number given is out of service, we will attempt
follow up using email or the second phone number provided by the participant. Each
participant will be allowed three unsuccessful phone calls and 1 email before being
considered lost to follow up.
The 6-month phone follow up will be answer any patient or caregiver questions, paying strict
attention to confidentiality, and will confirm contact information for subsequent 12-month
follow up. At 12-month follow-up, the patient's chart will be reviewed to assess for follow
up ED visits. A phone call will obtain contact information to 1) ask about non-Children's
National Health System ED visits, 2) quantify continued community resource use, and 3) to
obtain email or phone contact information through which the patient will complete the same
computerized screening tool. If adolescents report new suicidality, child-witnessed intimate
partner violence, physical or sexual abuse or human trafficking on the follow up survey, we
will proceed as described above.
All emergency intervention(s) the provider uses if a patient or caregiver screens positive
will be documented on an enrollment form. On non-social navigation days, providers will sign
a form acknowledging receipt of positive emergency screens and intervention materials. This
form will also allow the provider to ask research to contact social work on their behalf.
Randomization
Adolescent participants will be randomized to either receive or not receive social navigation
services using a random time and date generator to create social navigation and control
shifts that cover morning and evening shifts at both the Sheikh Zayed campus and UMC. This
study will employ a consecutive enrollment sampling technique during randomly selected blocks
to minimize selection bias. On social navigation shifts, the community health liaison, social
worker and clinician will be available. On non-social navigation shifts (control shifts),
patients will receive screening, a packet of community resources and follow-up phone calls to
confirm contact information and inquire about community resource use, but no social
navigation services.
