"Surviving critical illness is just the beginning of a long road to recovery, with lingering physical, cognitive, and psychological challenges known as post-intensive care syndrome."
The near-fatal cardiac arrest that befell Joseph Masterson, a Pittsburgh lawyer on the cusp of retirement, serves as a poignant illustration of a growing medical concern: post-intensive care syndrome (PICS). While Masterson’s story has a hopeful trajectory, his ongoing struggles with memory and cognitive function underscore the profound and often underestimated impact of prolonged intensive care unit (ICU) stays. This syndrome, affecting millions annually, highlights a critical gap in understanding and managing the long-term consequences of critical illness, even after a patient’s life has been saved.
The harrowing incident unfolded on November 16th when Masterson, then 63, experienced cardiac arrest while driving in Pittsburgh. His vehicle veered off course, striking a guardrail, before he lost consciousness. Fortunately, the quick actions of fellow motorists who broke his car window and extricated him, coupled with the intervention of a volunteer firefighter who administered CPR, provided a crucial lifeline. Masterson was then transported to UPMC Mercy hospital, marking the beginning of an arduous journey through the critical care system.
His 18-day stay in the medical intensive care unit was fraught with peril. Fourteen of those days were spent on a ventilator, a life-saving intervention that nonetheless carries significant risks. During this period, Masterson developed delirium, a common yet debilitating condition in ICUs characterized by a sudden disturbance in consciousness and cognitive function. This necessitated the use of antipsychotic medications, and despite the support of a feeding tube, he experienced significant weight loss. His brother-in-law, Ron Dedes, candidly admitted, "We honestly weren’t confident that he would pull through."
Against considerable odds, Masterson did recover sufficiently to be discharged on February 1st, returning home to a supportive family environment. The subsequent months have been dedicated to a rigorous rehabilitation regimen, involving various therapeutic interventions. He has made substantial progress, regaining his ability to walk, albeit with residual weakness, and managing his personal care needs. His speech, which had become garbled, has shown marked improvement, enabling him to perform simple tasks like making a sandwich.
However, the specter of PICS looms large, with memory impairment emerging as the most significant ongoing concern. "Our biggest concern is his memory," Dedes stated. Masterson, a man who once navigated complex legal matters, now struggles to recall recent conversations and events. His sister, Patti Dedes, noted his inability to operate a microwave or make a phone call, stark reminders of the cognitive toll. In a recent interview, Masterson acknowledged being "much, much better than I was," yet he misstated his age, a subtle yet telling indicator of cognitive deficits. Post-discharge screening tests confirmed cognitive impairment and depression, common components of PICS.
Post-intensive care syndrome, or PICS, is a term increasingly recognized among critical-care physicians to describe the constellation of new or worsening health problems that emerge after a patient has survived a critical illness and been discharged from the ICU. These aftereffects can manifest physically, psychologically, and cognitively, and their persistence can range from months to years, significantly impacting a patient’s quality of life and their ability to return to their pre-illness functional status. The risk of developing PICS is amplified by factors such as older age, longer ICU stays, and the severity of the initial critical illness.
The sheer volume of individuals experiencing ICU care underscores the widespread implications of PICS. Across approximately 5,000 American hospitals, more than 5 million people are admitted to intensive care annually. Disturbingly, research indicates that over half of these individuals will experience lingering aftereffects. This growing population of survivors grappling with PICS often finds themselves unprepared for the prolonged recovery period.
"The belief is that they’ll be discharged from the hospital and in two or three weeks, they’ll be back to normal," explained Dr. Brad Butcher, Masterson’s physician and a recent contributor to the medical journal JAMA on the topic of PICS. "That doesn’t comport with reality." The increasing survival rates in ICUs, attributed to advancements in medical technology and treatment protocols – with the Society of Critical Care Medicine estimating that 70% to 90% of adult ICU patients now survive their stays – paradoxically mean a larger population is susceptible to PICS.
Dr. Lauren Ferrante, a pulmonary critical-care physician and researcher at the Yale School of Medicine, emphasized this transition. "Everyone is grateful that the patient has survived," she noted. "But that’s just the start of a long road to recovery." Her research on patients aged 70 and older revealed that within six months of discharge, only about half had regained their pre-ICU functional ability, highlighting the significant and lasting impact of critical care.
The challenges faced by ICU survivors are multifaceted and extensive. PICS symptoms encompass a broad spectrum, from the purely physical, such as profound weakness, persistent pain, and neuropathy (nerve damage causing tingling or numbness), to the more insidious psychological impacts, primarily anxiety and depression. Cognitive difficulties, as exemplified by Masterson’s memory lapses, are also commonplace, including challenges with attention, concentration, and language processing.
"For many people, surviving a critical illness is a life-altering experience," Dr. Butcher stated. The impact extends beyond the initial recovery period, with studies showing that patients undergoing intensive care following emergency or elective surgery often experience new physical, mental, and cognitive problems a year later.
The very treatments that are instrumental in saving lives in the ICU can also contribute to the development of PICS. The aggressive interventions necessary to manage critical conditions, such as severe organ failure, often involve prolonged mechanical ventilation, requiring the use of sedating medications. "Sedation can precipitate delirium, and delirium is the key factor in cognitive symptoms," Dr. Butcher explained. Furthermore, the constant barrage of beeping monitors, round-the-clock lighting, and restricted family visiting hours can disrupt sleep, exacerbate anxiety, and deprive patients of crucial emotional support.
The disorienting and sometimes terrifying experiences within the ICU are not confined to the patient. Gregory Matthews, an 80-year-old retired accountant from St. Petersburg, Florida, recounted vivid hallucinations during his month-long ICU stay following a lung transplant in 2014, including seeing mice on the walls and believing he was being framed for drug running. At one point, he mistook a doctor for an assassin, leading him to jump out of bed and pull out his IVs, resulting in his arms being placed in restraints for days.
Physical immobility, a consequence of prolonged bed rest and necessary medical interventions, also exacts a significant toll. "Our bodies were not meant to lie in bed all day," Dr. Ferrante pointed out, referring to the rapid loss of muscle mass and strength that occurs. The psychological aftermath can be equally severe, with Dr. Carla Sevin, director of the ICU Recovery Center at Vanderbilt University Medical Center, noting that post-traumatic stress disorder (PTSD) is a common diagnosis, comparable to that experienced by combat veterans or sexual assault survivors. Families, too, can experience significant anxiety and depression as they navigate the challenging recovery process alongside their loved ones.
In response to these alarming outcomes, a growing number of U.S. hospitals are establishing dedicated post-ICU clinics. Approximately 35 such clinics are now operational, offering multidisciplinary teams—comprising physicians, nurses, pharmacists, and a range of therapists (physical, occupational, cognitive, and speech)—to screen for PICS-related conditions and guide patients through their recovery. Vanderbilt’s clinic, founded in 2012, was an early adopter, followed by the Critical Illness Recovery Center at the University of Pittsburgh Medical Center, established by Dr. Butcher in 2018 and which now serves approximately 100 patients annually, including Masterson. Yale launched its clinic in 2022, reflecting a broader recognition of the syndrome’s prevalence and impact.
These clinics often implement six key practices recommended by the Society of Critical Care Medicine, which have demonstrated significant reductions in post-ICU symptoms. These evidence-based strategies include employing lighter sedation, promoting earlier patient mobilization, daily breathing assessments to facilitate earlier liberation from ventilators, and removing restrictions on family visitation. Support groups for patients and families are also a vital component, fostering a sense of community and shared experience. Emerging evidence suggests that interventions such as maintaining an ICU diary, documenting experiences with patients and caregivers, and engaging in regular exercise and physical rehabilitation can positively impact mental health post-discharge.
A critical aspect of post-ICU care involves facilitating conversations about patient preferences for future critical illnesses. Given the potential for permanent impairment, some patients may opt for palliative care, focusing on comfort rather than aggressive life-sustaining treatments, should they face another life-threatening event. Dr. Butcher, while advocating for wider adoption of these new practices, remains optimistic about the future of critical care. "We’re going to find better diagnostic tools, better preventive strategies, and better therapies," he asserted.
However, the reality for many ICU survivors remains one of profound disorientation and trauma. When Dr. Butcher surveyed patients in his post-ICU clinic about their preferences for future medical interventions, a significant portion expressed a desire to limit aggressive care. Approximately one-third indicated they would opt for a lower level of intervention, with about a quarter of those considering "do not resuscitate" and "do not intubate" orders. Almost 7% stated they would never want to return to an ICU.
Joseph Masterson continues his diligent work toward recovery, acknowledging his current limitations. "I haven’t been out and about much," he admitted, describing himself as "homebound." His aspiration is to regain enough strength to resume running, a pastime he previously enjoyed several times a week. His pre-ICU physical fitness and his cognitively demanding career as a lawyer offer a positive outlook for his continued progress, according to Dr. Butcher.
Yet, for Masterson and his family, the future remains a landscape of both hope and uncertainty. "Down the road, what’s it going to be like?" his brother-in-law, Ron Dedes, mused, echoing the sentiment of many grappling with the long-term consequences of critical illness. For now, their approach is pragmatic: "We just take it day by day."
