Objectives • Describe features by which parents in the NICU experiencing acute or post-traumatic stress may be recognized. • Describe effective and supportive communication strategies when encountering NICU families in crisis. • Identify resources available to NICU parents suffering from emotional trauma. • All slides are available on our website (www.newbornmed.com)
Disclosures • I will not be discussing any experimental or off-label uses for any therapies during this presentation. • I have no relevant financial relationships to disclose.
One last disclaimer… • I am by no means an expert on mental health or psychological trauma. • I am a neonatologist who bears witness to the stress the NICU environment exerts on babies, their parents, and families.
Trauma? Yes! (For some.)
Trauma • “Experience of a threatening situation that goes beyond the bounds of the individual coping strategies and is accompanied by a sense of helplessness and defenseless abandonment.” (Yehuda, 2002).
Post-traumatic Stress Disorder (PTSD)(DSM-IV-TR) • A: Exposure to a traumatic event • (a) loss of "physical integrity", or risk of serious injury or death, to self or others, and • (b) an intense negative emotional response. • B: Persistent re-experiencing • One or more of these must be present in the victim: • Flashback memories, recurring distressing dreams, subjective re-experiencing of the traumatic event(s), or intense negative psychological or physiological response to any objective or subjective reminder of the traumatic event(s). • C: Persistent avoidance and emotional numbing • This involves a sufficient level of: • avoidance of stimuli associated with the trauma (thoughts, feelings, or talking about the event(s); • avoidance of behaviors, places, or people that could lead to distressing memories; • inability to recall major parts of the trauma(s), or decreased involvement in significant life activities; • decreased capacity to feel certain feelings; • an expectation that one's future will be somehow constrained in ways not normal to other people. • D: Persistent symptoms of increased arousal not present before • These are all physiological response issues, such as difficulty falling or staying asleep, or problems with anger, concentration, or hypervigilence. • E: Duration of symptoms for more than 1 month • If all other criteria are present, but 30 days have not elapsed, the individual is diagnosed with Acute Stress Disorder. • F. Significant impairment • The symptoms reported must lead to "clinically significant distress or impairment" of major domains of life activity, such as social relations, occupational activities, or other "important areas of functioning”
Fundamental question #1 • Are all the diagnostic criteria necessary for the traumatic event(s) to be important to a parent’s ability to cope and function?
Fundamental question #2 • How commonly are features of post-traumatic stress experienced by NICU parents?
Impact of NICU experience on parents • Sense of loss of personal control over events • Especially related to infant survival • Loss of role as decision maker and care giver • When is this regained? • discharge or beyond? • Appearance of fragile or sickly infant • Elevated distress leading to • Depression and anxiety • ASD and PTSD • Emotional distress correlated with • Infant maturity and complications (DeMeier, RL et al. (1996))
Literature review • Search criteria: • Primary research papers • English • Published in peer-reviewed journals • Participants: parents/caregivers of premature infants • Related to • Post-traumatic symptomatology following preterm birth • Traumatic experiences of parents with premature infants and/or • Effectiveness of interventions/treatment of post-traumatic symptomatology in parents following preterm birth
Wereszczak et al. (1997) • Objective: • Study vividness of memories recalled by primary caregivers after 3 years post preterm birth • Method: • Qualitative: Semi-structured interviews of 44 mothers or grandmothers • Findings: • At 3 years post-birth, caregivers report vivid memories related to infant appearance and behavior, pain, procedures, illness severity, and uncertainty of outcomes
Pierrhumbert et al. (2003) • Objective: • Examine effects of PTSD reactions of parents on sleeping and eating problems of former preterm infants. • Methods: • Perinatal PTSD questionnaire (PPQ, by DeMeir and Hynan et al, 1996) administered to 50 families (mothers and fathers) of former preterm infants and 25 families of full term infants at 18 months post-birth • Findings: • 67% of mothers of preemies vs. 6% controls exhibited clinical post-traumatic reactions at 18 mos. • Intensity of those reactions correlated with eating/sleeping problems of infants
Holditch-Davis et al. (2003) • Objective: • Investigate post-traumatic stress responses of mothers with premature infants • Methods: • Mixed qualitative-quantitative design w/ semi-structured interview screening for PTS features at enrollment and at 6 months corrected age • 30 mothers of high-risk preterm infants • Findings: • All mothers had at least one PTS symptom • 12 had two symptoms • 16 had three symptoms • Infant illness severity was significantly correlated with PTS symptoms
Kersting et al. (2004) • Objective: • Investigate PTS responses of mothers of premature infants • Methods: • Prospective longitudinal • 50 mothers of premature infants assessed with Impact of Events Scale (IES) (Horowitz et al. 1979) at 1-3 days, 14 days, 6 mos. and 14 mos. post-birth vs. 30 mothers of uncomplicated term infant births • Findings: • Higher rates of traumatic symptoms in mothers of preemies at all time points persisting without reduction at 14 mos. (p < .05)
Jotzo and Poets (2005) • Objective: • Investigate effectiveness of a trauma-preventative psychological intervention for parents of premature infants during hospitalization • Methods: • Sequential control-group design • 50 mothers of preemies enrolled: 25 in intervention group/25 in control group • Single session crisis intervention w/ psychologist w/ additional support throughout hospitalization when needed • Assessment at discharge w/ Impact of Event Scale (IES) • Findings: • 19 mothers in control group showed symptoms of clinical trauma post-birth compared to 9 in the intervention group
Shaw et al. (2009) • “The Relationship Between Acute Stress Disorder and Posttraumatic Stress Disorder in the Neonatal Care Unit”
“For Parents in NICU, Trauma May Last” By Laurie Tarkan August 25, 2009
Shaw et al. (2009) • Objective: • Examine the prevalence of PTSD in parents 4 months after the birth of preterm or sick infants • Examine the relationship between ASD symptoms immediately following birth and PTSD later on • Methods: • 18 parents completed completed a self-report assessment of ASD at baseline • Self-report assessment for PTSD and depression completed at 4 months.
Shaw et al. (2009) • Findings: • 33% of fathers and 9% of mothers met criteria for PTSD • ASD symptoms highly correlated with development of PTSD and depression • Fathers showed a more delayed onset in PTSD symptoms, but were at greater risk by 4 months than mothers
Feeley et al. (2011) • Objective: • examine how mothers’ PTSD symptoms affect mother-infant interaction • Methods: • self-report of 21 mothers of very low birthweight (<1500g) infants with (Perinatal PTSD Questionnaire (PPQ)) and Emotional Availability Scales at 6 months post discharge • Results: • 24% mothers attained scores c/w PTSD and these higher scores correlated with impaired effectiveness in structuring play with infant
Lefkowitz, et al. (2010) • Objective: • assess the prevalence and correlates of ASD and PTSD in mothers and fathers of NICU infants • Methods: • 86 mothers, 41 fathers self-reported ASD symptoms at enrollment and at PTSD +/- PPD via questionnaire at 30 days • Findings: • 35% of mothers and 24% of fathers met ASD criteria and 15% of mothers and 8% of fathers met PTSD criteria at 30 days. 39% of mothers met PPD criteria
Systematic review - findings • Research on the perspectives of NICU parents is limited • Studies had methodological limitations • Small size, high attrition rates • Single site • Little diversity • Time of assessment • Mothers vs. fathers • Lack of control for illness severity, length of stay, etc. • No clinician-administered assessment tool for PTSD • Intervention studies are particularly lacking • Limited information on effective strategies of support
Mackely, et al. (2010) • Objective: • evaluate presence of perceived stress in fathers of preterm infants over time • Methods: • self-report questionnaires (Parent Stressor Scale Infant Hospitalization (PSS:IH)) on DOL 7, 21, and 35 given to 35 fathers of preemies (less than 30 wks) • Results: • elevated stress scores persist over time without diminishing and do not correlate with demographic characteristics (marriage, education, insurance)
Future research • Standardized clinical scales along with open-ended interview schedules to obtain pre-post birth data • More long-term follow-up data needed • MORE FATHERS!!! in sampling; more racial diversity • Infant illness severity should be recorded • Attempt to correlate PTS symptoms with depression • Enhances recall bias of events?
Fundamental question #3 • Given a lack of evidence, what strategies of support/intervention should be offered in the NICU and after discharge?
Step one: Recognize the feelings • Terror • Grief • Impotence • Depression • Jealousy • Anger • “Even the most well-adapted appearing couple with an infant in the NICU is undergoing the most stressful crisis of their lives” • Rachael, Social Worker
POST- NATAL STRESS INVENTORYDeMeier et al. (1996) PLEASE CIRCLE "Y" IF YOU HAVE HAD ANY OF THESE EXPERIENCES SINCE THE BIRTH OF YOUR HIGH- RISK BABY. CIRCLE "Y" ONLY IF THE PARTICULAR EXPERIENCE LASTED FOR MORE THAN 1 MONTH DURING THIS TIME. • Y N 1. Did you have several bad dreams of giving birth or of your baby's hospital stay? • Y N 2. Did you have several upsetting memories of giving birth or of your baby's hospital stay? • Y N 3. Did you have any sudden feelings as though your baby's birth was happening again? • Y N 4. Did you try to avoid thinking about childbirth or your baby's hospital stay? • Y N 5. Did you avoid doing things which might bring up feelings you had about childbirth or your baby's hospital stay (for example, not watching a TV show about babies)? • Y N 6. Were you unable to remember parts of your baby's hospital stay? • Y N 7. Did you lose interest in doing things you usually do? (For example, did you lose interest in your work or in your family?) • Y N 8. Did you feel alone and removed from other people? (For example, did you feel like no one understood you?) • Y N 9. Did it become more difficult for you to feel tenderness or love with others? • Y N 10. Did you have unusual difficulty falling asleep or staying asleep? • Y N 11. Were you more irritable or angry with others than usual? • Y N 12. Did you have greater difficulties concentrating than before you gave birth? • Y N 13. Did you feel more jumpy? (For example, did you feel more sensitive to noise, or more easily startled?) • Y N 14. Did you feel more guilt about the childbirth than you felt you should have? Mothers of babies hospitalized in a NICU answer between 6 and 7 of the 14 items "Yes"; mothers of full-term, healthy infants answer 2.5 of the 14 items, "Yes"
Step two: Validate • Reassure parents that their emotions are a NORMAL response to severe stress • Mothers and fathers are more alike than different • Be wary of stereotyping • Use communication that focuses on the individual parent’s experience and emotions • Empathy • Encourage verbalization
A unique parent perspective • “You are going to be disorganized and upset for months—some of us for years. We feel crazy, and we want to return to normal quickly. But that is the worst thing that we can try to do, because we can’t stop or reverse the natural, healing process of our emotional reactions without doing damage to ourselves. The only things that are normal for high-risk parents are terror, grief, impotence, and anger… And experiencing these lousy emotions are signs that we parents are doing well, not poorly.”
A unique perspective • “… the medical staff can do wonderful things to help angry parents, even though I know that angry parents are one of the most troublesome things for you. It is natural for you to want to avoid angry parents, but please stay with us. When we erupt and explode, don’t go away, even though you have pressing obligations. Stay there, nod your heads, and let our anger blow past you like the desert winds. Then, in the next day or two, when you sense that we might be more rational, come back to us and re-establish communications. Go over what we were mad about, and show us that you believe that our feelings are important to you. This is crucial. Many times, trust is the only good feeling a parent has. If that trust ever disappears, then that is the worst crash on the roller coaster for parents.” • Michael Hynan, Ph.D. and parent of ex-preemie
Creating a supportive environment • Continuity of care • i.e. primary nurses • Family-centered care practices • Bedside rounding with families • On-site social workers • Parent-to-parent group • Advisor/leader (paid vs. volunteer) • Seamless transition at discharge to home • Engage parents in developmental care early • Encourage parenting competencies • Home nurse visits • Medical Home model • NICU Follow-up clinic
Supporting a family: where to refer? • Hospital social worker • Other resources • Pregnancy and Postpartum Support Minnesota (PPSM) • http://www.pregnancypostpartumsupportmn.com • mental health & perinatal practitioners, service organizations, and mother volunteers offering emotional support and treatment to Minnesota families through the perinatal years • Perinatal Mental Health Resource List, 4th Ed.
Conclusion • NICU hospitalizations generate stressful experiences for most, if not all, parents • Many will exert signs of acute and post-traumatic stress • Manifestations and likely effects vary among individuals • Future research needed to better understand the nature of ASD and PTSD in NICU parents and how we can best support these families
