in a previous issue of critical care , liu and colleagues embark upon a timely and important topic : visitation practices in us icus . because of these benefits , open and unrestricted visitation in icus has been recommended by critical care groups . however , liu and colleagues report that almost all us icus ( 90% ) have restrictive visitation policies , and most ( 62% ) have three or more restrictions . what is disconcerting is that these findings are not all that different from those reported in 2007 , where only 32% of icus had open visitation . even this statistic is misleading , because ' open ' referred only to the hours of visitation , and most icus considered open had restrictions on age and the number of visitors . liu and colleagues ' findings are also consistent with those from other countries where very few , if any , icus have open visitation policies . with all of the evidence guiding practice toward open visitation , open visitation has been studied from the perspective of the family and the healthcare provider , but very few studies have focused on the patient 's perspective . because icu patients are often unable to communicate their preferences about visitation , they are often excluded from research studies . however , olsen and colleagues interviewed 11 icu patients to gain their perspective on visitation . these patients stated that they felt supported when their families were present and were in favor of flexible visitation . yet most patients wanted some limitations , such as having only close family members visit . in addition , these patients felt stressed when trying to communicate with visitors and when thinking about how upsetting this experience was for their families . recently , hardin and colleagues surveyed 122 icu patients on their satisfaction with unrestricted visiting hours . their results support those of olsen and colleagues , since most patients wanted some restrictions and control over visitation . these two studies on the patient 's perspective indicate that the patient 's voice needs to be heard when developing visitation policies . another factor is the potential contributions of visiting icu family members to the well - being of their loved ones . interviews of 25 family members of 24 high risk of dying icu patients showed that families took on certain roles while in the icu and that they were physically and actively present in their loved ones ' care . these families reported that they were physically and actively present in their loved ones ' care . families ' contributions included protecting the patient , facilitating information , providing necessary patient history , comforting and motivating the patient , and performing caregiving activities . as a result , families believed the patient felt safer and more supported if they were present . others have found that families can contribute to patient care by keeping icu diaries for the patient . in families that kept diaries , researchers reported significantly lower post - traumatic stress symptoms in both patients and family members 12 months after the icu stay . investigators assessing this approach reported improved family satisfaction with communication and decision - making , both of which are important needs for families . families have much to offer , and allowing them open visitation could help them fulfill their roles , contribute to patient care , and decrease patient and family symptoms . one more factor is the healthcare provider . in a study comparing healthcare providers ' beliefs and attitudes toward open visitation nurses feared losing control of their icu room and felt that visits did not offer more comfort and support to the family . they also felt that open visitation hindered patient rest , infringed on patient privacy , and was an impediment to the nurses doing their job . in addition , there is a great deal of inconsistency among healthcare providers in the level of comfort they have in communicating with families . for example , those who feel more comfortable working with families may favor open visitation , whereas those who do not may want stricter visitation policies . liu and colleagues found this lack of consistency to be the case , with more restrictions in the northeast and fewer restrictions in the midwest and smaller hospitals . this lack of consistency , along with varying beliefs and attitudes toward visitation , can lead to confusion and resentment to all involved ( patient , family and healthcare provider ) and may be another factor as to why open visitation policies in icus continue to be elusive . first , it should be understood that open visitation is not a one - size - fits - all philosophy . second , it should be clarified that open visitation does not mean a free - for - all , with visitors being on the unit whenever they like . third , it is important to understand that addressing visitation is a complex process that means patient interests are accounted for , clinicians have improved communication skills , and families are supported and prepared for their visits . fourth , changing the terms ' open ' and ' unrestricted ' to ' flexible ' and ' liberal ' could help alleviate some of the barriers that healthcare providers have toward open visitation . finally , perhaps each icu will need to have an individualized approach to open visitation policies that meet the needs of the patient , the family , and the healthcare provider .
open visitation has been highly recommended by critical care groups but is not prevalent in practice . 
 here we discuss the present study on current visitation practices in us icus and discuss several factors affecting open visitation . 
 we conclude with suggestions on achieving more liberal visitation practices .
