Although survival is clearly an important and crucial outcome, the clinical condition after survival is also fundamental. Post Intensive Care Syndrome (PICS) is a multidimensional problem experienced after an Intensive Care Unit (ICU) stay, which can persist for several years.<a class="elsevierStyleCrossRef" href="#bib0130"><span class="elsevierStyleSup">1</span></a> PICS is described both for the patient (PICS-P) and their family (PICS-F).<a class="elsevierStyleCrossRefs" href="#bib0130"><span class="elsevierStyleSup">1–4,6,7</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">PICS-P includes non-physical components like anxiety, depression, post-traumatic stress disorder and cognitive impairment and physical problems like ICU acquired weakness, mobility impairment, glottis dysfunction, pain or pulmonary function impairment.<a class="elsevierStyleCrossRef" href="#bib0135"><span class="elsevierStyleSup">2</span></a> The real prevalence of PICS among ICU survivors is still unknown, with some studies reporting an incidence as high as 73% at hospital discharge and 46% one year after ICU.<a class="elsevierStyleCrossRefs" href="#bib0140"><span class="elsevierStyleSup">3,4</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">The National Institute for Health and Care Excellence published guidelines for managing rehabilitation after critical care and have proposed a care pathway for these patients.<a class="elsevierStyleCrossRef" href="#bib0150"><span class="elsevierStyleSup">5</span></a> In a first stage, at ICU admission patients at risk should be identified. Risk factors for PICS-P are based both on patient background and acute illness features. Previous mobility, respiratory or cognitive impairments, long expected ICU stay, physical or neurological injury, acute physical impairment and severe respiratory failure are risk factors for physical PICS components. On the other hand, risk factors for psychological PICS are previous psychiatric disorder, dementia or story at ICU of nightmares, intrusive memories, anxiety, recurrent panic attacks and refusing to talk about the disease. On a second stage, PICS components should be identified before ICU discharge and rehabilitation should be started as soon as possible. After discharge, a follow-up team should accompany the patient during ward based-care focused on rehabilitation goals and a revaluation should be made before discharge to home or community. In a fourth stage, the patient should be revaluated 2 to 3 months after critical care.<a class="elsevierStyleCrossRef" href="#bib0150"><span class="elsevierStyleSup">5</span></a></p><p id="par0020" class="elsevierStylePara elsevierViewall">Although most of the studies done after ICU care are focused in the patient despite the recognition that they are not the only ones affected by ICU stay. Caregivers play a crucial role in patients’ recovery and they face themselves many stressors like fearfulness, disruption of family dynamics, financial pressure and work overload, all of which can contribute to caregiver burden.
