Hospitalized Medical Patients with Posttraumatic Stress Disorder (PTSD): Review of the Literature and a Roadmap for Improved Care

Abstract

Posttraumatic Stress Disorder (PTSD) is common in the United States, with a prevalence of nearly 8% in the general population and between 10%-30% in veterans. Despite how common PTSD is, inpatient providers may not be familiar with its manifestations or feel comfortable taking care of patients who may exhibit symptoms related to it. In our combined experience as VA-based hospital medicine care providers, we have cared for thousands of patients hospitalized for a primary medical condition who also have PTSD as a comorbidity. We have noticed in our practices that we only focus our attention on PTSD if a related problem arises during a patient’s hospitalization (eg, confrontations with the care team or high levels of anxiety). We contend that a more proactive approach could lead to better care, but little evidence about best practices exists to inform the interdisciplinary team how to optimally care for hospitalized medical patients with PTSD. In this narrative review, we present a synthesis of existing literature, describe how trauma-informed care could be used to guide the approach to patients with PTSD, and generate ideas for changes that inpatient providers could implement now, such as engaging patients to prevent PTSD exacerbations and promoting better sleep in the hospital.

Posttraumatic Stress Disorder (PTSD) is a syndrome that occurs after exposure to a significant traumatic event and is characterized by persistent, debilitating symptoms that fall into four “diagnostic clusters” as outlined in the Diagnostic and Statistical Manual of Mental Disorders-Version V (DSM-V). Patients may experience intrusive thoughts, avoidance of distressing stimuli, persistent negative mood, and hypervigilance, all of which last longer than 1 month.1

A national survey of United States households conducted during 2001-2003 estimated the 12-month prevalence of PTSD among adults to be 3.5%.2 Lifetime prevalence has been found to be between 6.8%3 and 7.8%.4 PTSD is more common in veterans. The prevalence of PTSD in veterans differs depending on the conflict in which the veteran participated. Vietnam veterans have an estimated lifetime prevalence of approximately 30%,5,6 Gulf War veterans approximately 15%,7 and veterans of more recent conflicts in Afghanistan and Iraq of approximately 21%.8 With the MISSION Act moving more veteran care into the private sector, non-VA inpatient providers will need to become better versed in PTSD.9

Patients with PTSD have more contact with the healthcare system, even for non–mental health problems,8,10-13 and a significantly higher burden of medical comorbities,14 such as diabetes mellitus, liver disease, gastritis and gastric ulcers, HIV, arthritis,15 and coronary heart disease.16 Veterans with PTSD are hospitalized three times more often than are those with no mental health diagnoses,8 and patients with psychiatric comorbidities have higher lengths of stay.17 More than 1.4 million hospitalizations occurring during 2002-2011 had either a primary or secondary associated diagnosis of PTSD, with total inflation-­adjusted charges of 34.9 billion dollars.18 In the inpatient sample from this study, greater than half were admitted for a primary diagnosis of mental diseases and disorders (Major Diagnostic Category [MDC] 19). Following mental illness, the most common primary diagnoses for men were MDC 5 (Circulatory System, 12.1%), MDC 20 (Alcohol/Drug Use or Induced Mental Disorder, 9.2%), and MDC 4 (Respiratory System, 7.4%), while the most common categories for women were MDC 20 (Alcohol/Drug Use or Induced Mental Disorder, 5.8%), MDC 21 (Injuries, Poison, and Toxic Effect of Drugs, 4.9%), and MDC 6 (Digestive System, 4.5%).18

In both the inpatient and outpatient settings, a fundamental challenge to comprehensive PTSD management is correctly diagnosing this condition.19 Confounding the difficulties in diagnosis are numerous comorbidities. In addition to the physical comorbidities described above, more than 70% of patients with PTSD have another psychological comorbidity such as affective disorders, anxiety disorders, or substance use disorder/dependency.20

Given that PTSD may be an underrecognized burden on the healthcare system, we sought to better understand how PTSD could affect hospitalized patients admitted for medical problems by conducting this narrative review. Additionally, three of the authors collaborated with the VA Employee Education Service to conduct a needs assessment of VA hospitalists in 2013. Respondents identified managing and educating patients and families about PTSD as a major educational need (unpublished data available upon request from the corresponding author). Therefore, our aims were to present a synthesis of existing literature, familiarize readers with the tenets of trauma-­informed care as a framework to guide care for these patients, and generate ideas for changes that inpatient providers could implement now. We began by consulting a research librarian at the Clement J. Zablocki VA Medical Center in Milwaukee, Wisconsin, who searched the following databases: PsycInfo, CINAHL, MEDLINE, and PILOTS (a PTSD/trauma specific database). Search terms included hospital, hospitalized, and hospitalization, as well as traumatic stress, posttraumatic stress, and PTSD. Pertinent guidelines and the reference lists from included papers were examined. We focused on papers that described patients admitted for medical problems other than PTSD because those patients who are admitted for PTSD-­related problems should be primarily ma­naged by psychiatry (not hospitalists) with the primary focus of their hospitalization being their PTSD. We also excluded papers about patients developing PTSD secondary to hospitalization, which already has a well-developed literature.21-23

THE LITERATURE ABOUT PTSD IN HOSPITALIZED PATIENTS

The literature is sparse describing frequency or type of problems encountered by hospitalized medical patients with PTSD. A recent small survey study reported that 40% of patients anticipated triggers for their PTSD symptoms in the hospital; such triggers included loud noises and being shaken awake.24 Two papers describe case vignettes of patients who had exacerbations of their PTSD while in the Intensive Care Unit (ICU), although neither contain frequency or severity data.25,26 Approximately 8% of patients in VA ICUs have PTSD,27 and a published abstract suggests that they appear to require more sedation than do patients without PTSD.28 Another published case report describes a patient with recurrent PTSD symptoms (nightmares) after moving into a nursing home.29 These papers suggest other providers have recognized and are concerned about hospitalized patients with PTSD. At present, there are no data to quantify how often hospitalized patients have PTSD exacerbations or how troublesome such exacerbations are to these patients.

Given that there is little empiric literature to guide inpatient management of PTSD as a comorbidity in hospitalized medical patients, we extrapolate some information from the outpatient setting. PTSD is often underdiagnosed and underreported by individual patients in the outpatient setting.30 Failure to have an associated diagnosis of PTSD may lead to underrecognition and undertreatment of these patients by inpatient providers in the hospital setting. Additionally, the numerous psychological and physical comorbidities in PTSD can create unique challenges in properly managing any single problem in these patients.20 Armed with this knowledge, providers should be vigilant in the recognition, assessment, and treatment of PTSD.

INPATIENT MANAGEMENT OF PTSD

Trauma-Informed Care: A Conceptual Model

Trauma-informed care is a mindful and sensitive approach to caring for patients who have suffered trauma.31 It requires understanding that many people have suffered trauma in their lives and that the trauma continues to impact many aspects of their lives.32 Trauma-informed care has many advocates and has been implemented across myriad health and social services settings.33 Its principles can be applied in both the inpatient and outpatient hospital settings. While it is an appropriate approach to patients with PTSD, it is not specific to PTSD. People who have suffered sexual trauma, intimate partner violence, child abuse, or other exposures would also be included in the group of people for whom trauma-informed care is a suitable approach. There are four key assumptions to a trauma-­informed approach to care (the 4 R’s): (1) realization that trauma affects an individual’s coping strategies, relationships, and health; (2) recognition of the signs of trauma; (3) having an appropriate, planned response to patients identified as having suffered a trauma; and (4) resisting retraumatization in the care setting.31,32

General Approach to Treating Medical Patients With PTSD in the Inpatient Setting

Recognition

Consistent with a trauma-informed care approach, inpatient providers should be able to recognize patients who may have PTSD. First, careful review of the past medical history may show some patients already carry this diagnosis. Second, patients with PTSD often have other comorbidities that could offer a clue that PTSD could be present as well; for example, risk for PTSD is increased when mood, anxiety, or substance use disorders are present.20 When PTSD is suspected, screening is a reasonable next step.

The Primary Care-PTSD-5 (PC-PTSD-5) is a validated screening tool used in the outpatient setting.34 It is easily administered and has good predictive validity (positive likelihood ratio [LR+] of 6.33 and LR– of 0.06). It begins with a question of whether the patient has ever experienced a trauma. A positive initial response triggers a series of five yes/no questions. Answering “yes” to three or more questions is a positive screen. A positive screen should result in consultation to psychiatry to conduct more formal evaluation and guide longer-term management.

Collaboration

Individual trauma-focused psychotherapy is the primary treatment of choice for PTSD with strong evidence supporting its practice.35 This treatment is administered by a psychiatrist or psychologist and will be limited in the inpatient medical setting. Current recommendations suggest pharmacotherapy only when individualized trauma-focused psychotherapy is not available, the patient declines it, or as an adjunct when psychotherapy alone is not effective.36 Therefore, inpatient providers may see patients who are prescribed selective serotonin reuptake inhibitors (eg, paroxetine, fluoxetine) or serotonin and norepinephrine reuptake inhibitors (eg, venlafaxine).36 In the past, PTSD-related nightmares were often treated with prazosin.37 However, a recent randomized controlled trial of prazosin in veterans with PTSD failed to show significant improvement in nightmares.38 Hence, current guidelines do not recommend prazosin as a first-line therapy.39 For hospitalized patients with PTSD symptoms refractory to the interventions outlined herein, particularly those patients with possible borderline personality traits (as suggested by severe anger and impulsivity), we strongly recommend partnering with psychiatry. Finally, given the high prevalence of substance use disorders (SUDs) in PTSD patients, awareness and treatment of comorbidities such as opioid and alcohol dependence must be concurrently addressed.

Individualizing Care

It is essential for the healthcare team to identify ways to meet each patient’s immediate needs. Many of the ideas proposed below are not specific to PTSD; many require an interprofessional approach to care.40 From a trauma-informed care standpoint, this is akin to having a planned response for patients who have suffered trauma. Assessing the individual’s needs and incorporating therapeutic modalities such as reflective listening, broadening safe opportunities for control, and providing complementary and integrative medicine (IM) therapies may help manage symptoms and establish rapport.41 Through reflective listening, a collaborative approach can be established to identify background, triggers, and a safe approach for managing PTSD and its comorbid conditions. Ensuring frequent communication and allowing the patient to be at the center of decision-making establishes a safe environment and promotes positive rapport between the patient and healthcare team.36 Providing a sense of control by involving the patients in their healthcare decisions and in the structure of care delivery may benefit the patients’ well-being. Furthermore, incorporating IM encourages rest and relaxation in the chaotic hospital environment. Suggested IM interventions include deep breathing, aromatherapy, guided imagery, muscle relaxation, and music therapy.42,43

Key Inpatient Issues Affecting PTSD

In the following sections, we outline common clinical situations that may exacerbate PTSD symptoms and propose some evidence-based responses (Table). In general, nonpharmacologic approaches are favored over pharmacologic approaches for patients with PTSD.

Possible Strategies for Preventing/Treating PTSD Exacerbations in Hospitalized Patients
Sleep Hygiene

Sleep problems are very common in patients with PTSD, with nightmares occurring in more than 70% of patients and insomnia in 80%.44 In PTSD, sleep problems are linked to poor physical health and other health outcomes45,46 and may exacerbate other PTSD symptoms.4

Treating the sleep problems that occur with PTSD is an important aspect of PTSD care. Usually administered in the outpatient setting, the treatment of choice is cognitive-behavioral therapy (CBT).48 Sleep-specific CBT focuses, among other things, on strategies that encourage good sleep hygiene,49 which includes promoting regular sleep/wake-up times and specific bedtime routines, avoiding stimulation (eg, light, noise, TV) or excessive liquids before bed, refraining from daytime naps, and using relaxation techniques. Many of these recommendations seem at odds with hospital routines, which may contribute to decompensation of hospitalized patients with PTSD.

While starting sleep-specific CBT in the hospital may not be realistic, we suggest the following goals and strategies as a starting place for promoting healthy sleep for hospitalized patients with PTSD. To begin, factors affecting sleep hygiene should be addressed. Inpatient providers could pay more attention to intravenous (IV) fluid orders, perhaps adjusting them to run only during the daytime hours. Medications can be scheduled at times conducive to maintaining home routines. Avoiding the administration of diuretics close to bedtime may decrease the likelihood of frequent nighttime wakening. Grouping patient care activities, such as bathing or wound care, during daytime hours may allow more opportunities for rest at night. Incorporating uninterrupted sleep protocols, such as quiet hours between 10pm and 6am, may enhance sleep quality in the appropriately selected patient.50 Although pharmacological interventions to improve sleep in the hospital may be initially beneficial, nonpharmacological interventions as described above should be incorporated for long-term maintenance of enhanced sleep quality.

Second, providers need to ask about established home bedtime routines and facilitate implementation in the hospital. Through collaboration with patients, providers can incorporate an individualized plan of care for sleep early in hospitalization.50 Partnering with nurses is also essential to creating a sleep-friendly environment that can improve patient experiences.51 Breathing exercises, meditating, listening to music and praying are all examples of “bedtime wind down” strategies recommended in sleep-specific CBT.49 Many of these could be successfully implemented in the hospital and may benefit other hospitalized patients too.52 In patients with PTSD and obstructive sleep apnea, continuous positive airway pressure (CPAP) reduces nightmares, and if inpatients are on CPAP at home, it should be continued in the hospital.53

Pain

If sleep disturbance is the hallmark of PTSD,47 chronic pain is its coconspirator.15 Uncontrolled pain can make it much more difficult to treat patients with PTSD, which in turn may lead to further decompensation from a mental health standpoint.54 SUDs such as alcohol or opioid dependencies are highly comorbid with PTSD45 and introduce a layer of complexity when managing painin these patients. Providers should be thoughtful when electing to treat acute or chronic pain with opioids and take particular care to establish realistic therapeutic goals if doing so. While patients with PTSD have a greater likelihood of having an SUD, undertreating pain risks exacerbating underlying PTSD symptoms.

Nonpharmacologic therapies, which include communicating, listening, and expressing compassion and understanding, should be utilized by inpatient providers as a first-line treatment in patients with PTSD who suffer from pain. Additionally, relaxation techniques, physical therapy, and physical activity55 can be offered. Pharmacologically, nonopioid medications such as acetaminophen or NSAIDs should always be considered first. Should the use of opioids be deemed necessary, inpatient providers should preferentially use oral over intravenous medications and consider establishing a fixed timeframe for short-term opioids, which should be limited to a few days. Providers should communicate clear expectations with their patients to maximize the desired effect of any specific treatment while minimizing the risk of medication side effects with the goal of agreeing on a short yet effective treatment course.

Anxiety and Anger

One of the most challenging situations for the inpatient provider is encountering a patient who is anxious, angry, or hypervigilant. Mismatch between actual and expected communication between the provider and the patient can lead to frustration and anxiety. A trauma-informed care approach would suggest that frequent and thorough communication with patients may prevent or ameliorate the stresses and anxieties of hospitalization that may manifest as anger because of retraumatization. Hospitalizations usually lead to disruption of normal routine (eg, unpredictable meal times or medication administration), interrupted sleep (eg, woken up for blood draws or provider evaluation), and lack of control of schedule (eg, unsure of exact time when a procedure may be occurring), any of which may trigger symptoms of anxiety and anger in patients with PTSD and lead to hypervigilance.

If situations involving patient anxiety do arise, employ compassion and communication. Extra time spent with the patient, while challenging in the hectic hospital environment, is critical, and nonpharmacological treatments should be the priority. Engaging patients by asking about their PTSD triggers24 may help prevent exacerbations. For example, some patients may specify how they prefer to be woken up to prevent startle reactions. PTSD triggers can be reduced via effective communication with the entire healthcare team. Some immediate yet effective strategies are listening, validation, and negotiation. Benzodiazepine or antipsychotic usage should be avoided.36 Inpatient social work and comanagement with psychiatry involvement may be helpful in more severe exacerbations. A small observational study of patients hospitalized for severe PTSD found an association between walking more during hospitalization and fewer PTSD symptoms,56 suggesting that staying active could be helpful for inpatients with PTSD who are able to safely ambulate.

SUMMARY

PTSD is a common comorbidity among hospitalized patients in the United States. Typical hospital routines may exacerbate symptoms of PTSD such as anxiety and anger. Inpatient providers can play an important role in making hospitalizations go more smoothly for these patients by using principles consistent with trauma-informed care. Specifically, partnering with patients to construct a plan that preserves their sleep routines and accounts for potential triggers for decompensation can improve the hospital experience for patients with PTSD. Some PTSD interventions require additional investment from the healthcare system to deploy, such as staff training in trauma-­informed care and reflective listening techniques. Electronic health record–based protocols and order sets for patients with PTSD can leverage available resources. Further research should evaluate hospital outcomes that result from a more tailored approach to the care of patients with PTSD. More effective, patient-centered PTSD care could lower rates of leaving against medical advice and improve the inpatient experience for patients and providers alike.
