    Summary   Although nurses realise the importance of the family in holistic care of the patient, often they are reluctant to integrate family into the ICU environment.The family role in patient healing has been minimised. There is incongruence innurses’ assessments and families’ perceptions of what constitutes caring behaviours.Traditionally ICUs have been primarily patient focused; changing to family-centredwill require attitude changes and a multidisciplinary team approach to care. Studieshave shown families to be stressed and at significant risk for maladaptation whenacute illness or trauma strikes. Nurses potentially may alter family stress responsesthrough caring behaviours, and a family-centred approach to care.© 2004 Elsevier Ltd. All rights reserved.

    Family integration into intensive care units (ICUs)and creation of a family-centred approach to careare important in providing holistic care to patientsand in helping families decrease their stress lev-els. Family members of critically ill or injured pa-tients become the representatives for the patientwhen self-representation is not feasible due to thenature of the illness or injury. Families confrontlife and death issues, role reversals, financial con-cerns, and added family responsibilities, all poten-tially major sources of stress, anxiety, and barriersto adaptation (Leske, 2003). Anxiety and depres-sion are commonplace. In Pochard et al. (2001) sur-vey that incorporated 43 ICUs, the results revealedthat greater than 60% of the family members ex-

    hibited anxiety and stress symptoms. Encompassingthe family into the care of the patient and the in-tensive care environment may represent a pivotalpoint for successful family adaptation and well be-ing of its members.

    Nurses may be reluctant, inconsistent or evenfail to consider the implications of excluding thefamily (Tracy and Ceronsky, 2001). ICU nurses arepositioned where caring is focused on the patient;to provide holistic care however, caring cannot ex-clusively be directed to the patient, especially inthe context of critical illness. Care of the patientand care of the family become intertwined. Whataffects one member potentially impacts the entirefamily. ‘Caring for the family is a component of car-ing for the patient and is achieved by supportingand involving the family in caring’ (Beeby, 2000,p. 159). Not only is the well being of the patient

    at stake, but also the family members are at sig-nificant risk for maladaptation. Achieving holismand family-centredness depends on the nurses’ re-sponses to family care and their willingness to finda fit for the family in the ICU environment.

    The purpose of this inquiry was to examine,through literature review, the effects of nurse car-ing behaviours and a family-centred approach tocare on family stress responses related to acute ill-ness or trauma. The assumptions supporting this re-view included the following:

    •  Families play a vital role in patient healing; in-clusion is necessary in providing holistic care.

    •   Families coax, support and encourage the ill fam-ily member enhancing earlier recovery potential.

    •  Families are at significant risk for health conse-quences. Illness or injury does not occur in isola-tion but involves the entire family.

    •   Nurses are positioned to support families in deal-ing with stress. Nurse attributes and nurse caringbehaviours set the stage to make it happen.

    The current relevant nursing literature from1999 through 2004 was searched using the elec-tronic databases CINAHL, MEDLINE, PubMed andOVID Online in order to locate studies relevant tothe selected topic. Key words and combinations of the key words were used relating to adult ICU, nursecaring behaviours, family stress and stress percep-tion, and family responses to members’ hospitali-sation. The focus of the search was narrowed and

    the selected studies were critiqued. Research withevidenced-based outcomes on how nursing, throughnurse caring behaviours and a family-centred ap-proach to care, without exclusion of any impor-tant members, conceptually and holistically metfamily demands and decreased family stress re-sponses in adult critical care were included. In ad-dition, abstracts were reviewed in the  Journal of Holistic Nursing, Dimensions of Critical Care, andCritical Care Nurse   in search of pertinent studies.Studies that primarily examined family needs wereexcluded.

    Definition of terms

    Nurse caring behaviours are a function of nursingattitudes, skills, and knowledge employed in thecare of patients and families that serve to positivelyinfluence, support, or enhance nursing care. Per-ception of what constitutes nurse caring however isdependent on the recipient of care. Family-centredcare is inclusive of those persons significant tothe patient regardless of biological relationship.Stress response is based on family stress theory

    (Patterson, 2002). Consistent with Patterson’s the-ory, families work to balance demands with capabil-ities in order to achieve adaptation. When demandsexceed capabilities, crisis results. In the event of critical illness or injury, family function and thehealth of family members are at risk.

    Literature review

    Nurses recognize the importance of nurse/familyinteractions to the welfare of both the patientand family. More than 90% of emergency room (ER)nurses, in an Icelandic study, acknowledged fam-ily care taking as comprising a significant part of the nursing role (Hallgrimsdottir, 2000). In a Finnishstudy of 165 hospital staff, two thirds of the respon-

    dents felt nurse/family interactions to be vital inprovision of holistic care for the patient and an im-portant determinant of family health and successfulcare of the patient post-hospital discharge (Astedt-Kurki et al., 2001).

    A correlation was also discovered between theexperience of the nurse and the perception of theimportance of the family to the well being of thepatient. Nurses with less work experience tendedto place less emphasis on nurse/family interactions(Astedt-Kurki et al., 2001; Beeby, 2000). Experi-ence also seemed a determinant in the ability of the nurse to provide emotional support. Beeby’s

    (2000) investigation revealed that the less experi-enced nurses needed to develop expertise in phys-ical caring for the patient prior to readiness foremotional care of the family.

    Through nurses’ experiences of caring for familymembers, nurses gain knowledge of the patient andcome to know the patient through the insight pro-vided by family members. Nurse caring behavioursbecome less mechanistic as nurses grow to knowthe patient as a person instead of an object of care (Hardicre, 2003).  Benner’s reflection on car-ing (2003) offers insight into the ontology of caring

    and caring behaviours, what it means to care, andthe possibilities inherent in the concept. Caring isconcern outside of oneself about what matters, asense of connection that leads to development of trust.

    ‘Because caring sets up what matters to the person,it sets up what counts as stressful, and what optionsare available to the person for coping. This is thefirst way in which caring is primary. It determinesboth what will be stressful and what will count ascoping.’ (Benner, 2003, p. 166)

    Family stress response

    Nursing research has sought to illuminate family re-sponses and functioning following critical illness of a family member (Astedk-Kurki et al., 1999; Butteryet al., 1999; Hupcey and Penrod, 2000; Van Hornand Tesh, 2000a,b). When acute illness or traumastrikes, families are caught off guard; life becomesdisorganized and disrupted as demands exceed ca-pabilities. The entire family is deeply impacted andmust find ways of dealing with the associated stress.

    Following Newman’s (1999) concept of rhythmi-cally relating to another, families are in a sense‘dysrhythmic’ following admission of a family mem-ber to ICU, often erratically thinking and out of syn-chronisation. Perceived life-altering changes andthe potential of death are issues the family mustconfront. The chaos of seemingly endless decisionsfrom moment to moment while family members at-

    tempt to make sense of events increases familystress and may overwhelm to the point of hinderingdecision-making and ultimately, family function.Increased demands, an unfamiliar and seeminglythreatening and hostile technological environment,in addition to an array of prior life stressors, chal-lenge the family attempt to expand capabilities tomeet demands.

    Interventions become paramount in facilitatingfamily efforts in reaching a state of equilibriumand in regaining a sense of synchrony in their livesthat has been swept away by the acute illness

    or traumatic event. Instead families wait and arekept ‘waiting to know’ and may be treated as out-siders rather than included as partners in care.Families struggle to find meaning and balance inlife and ways of dealing with stress and upheaval(Patterson, 2002).

    In the process, families experience a range of feelings including aloneness, anticipation, sorrow,worry, anxiety, and depression, each suffering in away unique to that individual (Astedk-Kurki et al.,1999). In the investigation of Astedt-Kurki et al. intothe experiences of the family when a member ishospitalised, the immediate family members (87%)

    who interacted on a daily basis and depended on thefamily member for their contribution in daily livingwere more greatly impacted by critical illness thanthose who spent less time in interactions. The like-lihood exists that a spouse more than other familymembers will suffer symptoms of anxiety, depres-sion, and stress (Leske, 2003).

    Family response to stress and eventual cop-ing is dependent on family perception of stress,strengths, and perceived lifestyle changes associ-ated with critical illness (Patterson, 2002). Patter-son, using the Family Adjustment and Adaptation

    Response (FAAR) Model, defined family core func-tions and the adaptation process family employ inreaching a level of adaptation. Four concepts of family functions were designated as the core func-tions: membership, economic support, socializationand protection. Families derive situational mean-ings from the way they view their world. When de-mands of daily living balance with capabilities, theresult is adaptation; during times of crisis the capa-bilities are outweighed by demands. At this criticaljuncture, core family functions are significantly atrisk for disruption. The predominant family questsare to restore balance and gain resilience.

    Families engage in tactics to ‘work through’ theissues in order to balance demands, put the puz-zle pieces together and clarify the issues that con-front them (Buttery et al., 1999). They experiencea sense of aloneness; they must ‘endure’ and shoul-der all the responsibilities (Hupcey and Penrod,

    2000). Physical and emotional health is impactedas eating and sleeping patterns become sporadic(Van Horn and Tesh, 2000a,b).  Van Horn and Tesh(2000a), utilizing the Iowa ICU Family Scale (IIFS),explored variations in health habits, role changes,and support systems during family members’ hos-pitalisation. The IIFS instrument uses a Likert scaleto compare pre-hospitalisation behaviours with cur-rent behaviours. In this study of a non-probabilitysample of 50 family members of ICU patients, 56%experienced changes in family roles. More than 80%were at significant risk for illness based on sleep

    deprivation and impaired nutrition without consid-eration of the stress component of illness.Van Horn and Tesh (2000a) also established a cor-

    relation between the frequency of visitation andstress scores. Those who visited the patient morefrequently had higher initial stress scores, levellingoff after about 20 days length of stay. Highest stressscores and more health habit changes came fromwomen in the 19 to 29 and 30 to 39 age groups.Young families who have the added responsibilitiesof children may feel changes in roles and respon-sibilities more severely, accounting for the higherstress scores.

    Pre-existing family stress may influence the abil-ity of the family to cope with current stressors. Ina comparison study of family stress and strengthsfollowing surgery and trauma, Leske (2000)  foundmechanism of injury had an insignificant bearingon strengths and adaptation. However, prior stresswas found to be more a determinant of copingability than the current illness event. When fam-ily stress and strengths after various modes of trauma, surgery and gunshot wounds (GSW) werecompared, families of GSW victims were likely tohave more prior stress and fewer coping skills.

    experience (Wolf et al., 2003). The CBI, also basedon Watson’s theory of caring, categorizes nurse car-ing into five main areas. Nurse caring responses in-clude those that demonstrate respect of the client,provide assurance, offer a positive sense of connec-tion to others, pay attention to the needs of others,and use skills and knowledge in caring behaviours.

    Other studies have suggested the perceived im-portance of individuality on the patient concept of what constitutes caring. A British study by Attree(2001) on nurse caring behaviours from the familyand patient prospective described ‘good’ and ‘notso good’ quality care. Patient focused care relatingto the patients’ needs and described by the patientsas ‘made you feel like you were the one that counts’ranked highly on the list. The interpersonal aspectsof caring were defined as the most significant topatients and relatives in this qualitative study.

    Supportive of this research is the study of 

    Dingman et al. (1999) concerning patient satisfac-tion with care after implementing a caring modelbased on Watson’s caring attributes. As nursesshowed more concern for individual patient identi-fied needs, overall satisfaction with care improved.The exploration of  Hegedus (1999) into caring be-haviours also revealed agreement between nursesand patients on the importance of the concept of in-dividuality. While both groups’ perceptions differedon what constitutes the most caring behaviours,both ranked ‘treatment as an individual’ as themost important caring behaviour.

    Showing individual concern does not need to en-compass a vast quantity of time. Addressing thetime factor needed to care, in   Dingman et al.(1999) survey of patient satisfaction with hospital-isation, the importance of a caring moment wasdemonstrated. The quality of communication farexceeded the importance of length of time spentin the endeavour. Five minutes spent with the pa-tient or family explaining the plan of care for theday brought satisfaction and an expressed sense of feeling cared for.

    For caring to be meaningful, both the carerand the one being cared for must share common

    perceptions. In comparison studies of nurse car-ing examined from patient and staff perspectives,incongruence was evident (Hegedus, 1999; vonEssen and Sjoden, 2003). Eighty-one patients and105 staff from six hospitals participated in von Es-sen’s project. Using a CARE-Q instrument, whichidentified 50 nurse caring behaviours, divided intosix categories, behaviours are chosen in rank or-der according to specific sets of instructions. Fromnursing’s perspective, affective behaviours such aslistening, touch, assurance, allowing for individual-ity and spending time with the patient were con-

    sidered the most important caring behaviours. Incomparison, patients rated the technical aspectsof care more highly. Perception of patient and staff differed on greater than 50% of the items on theCare-Q scale. Consistently, in both studies, nursesrated affective behaviours more highly than did pa-tients.

    Meeting family needs

    The categorical needs of family members of criticalcare patients have been well established throughprior research. These include the need for infor-mation, proximity to the family member, assurancethat the best possible care is given to the familymember, support, and comfort (Leske, 2002). Leskerefined the previous work of Molter, which identi-fied 45 family needs into a quantitative measure,

    the Critical Care Family Needs Inventory (CCFNI).Now an evaluation of nursing in meeting identifiedneeds, examining the progress that has been made,is being addressed in nursing research. Unmet needsmultiply family stress responses.   Kosco and War-ren’s (2000) evaluation of 45 family members in aLevel 3 trauma centre discovered that families andnurses do not always agree on the perception of needs as met. Only 4 of the 10 family needs identi-fied on the CCFNI were ranked as being met.

    Nurse caring behaviours in family care, ideallywould be directed toward fulfilling families’ identi-

    fied needs. The studies by   Hallgrimsdottir (2000)and Astedk-Kurki et al. (2001) confirmed nurses’acknowledgement of the importance of family inprovision of holistic care. However, nurses are in-consistent in meeting family needs mainly becauseof differing beliefs in obligations to family care(Hallgrimsdottir, 2000; Hupcey, 1999; Tracy andCeronsky, 2001).

    Other examples of disparity exist between whatthe family and patient consider the most importantand what the nurse considers important (Kosco andWarren, 2000; Mi-kuen et al., 1999). In a study of neurosurgical patients in Hong Kong, nurses tended

    to underestimate those items that the family con-sidered most significant (Mi-kuen et al., 1999).Nurses rated support and comfort needs decidedlyhigher while the family valued information, espe-cially from the same nurse, proximity to the pa-tient, and assurance through offering hope.

    A commonality and a frequent utterance of fam-ilies, as they deal with the crisis brought on bycritical illness, was the need to know (Bond et al.,2003; Hunsucker et al., 1999; Yin King Lee and Lau,2003). Bond et al. (2003) found this especially appli-cable to families of severe traumatic brain injured

    patients. The need for consistent, accurate infor-mation was important initially and remained impor-tant to the family over time and throughout theICU experience. The findings of the survey of   YinKing Lee and Lau (2003)  of 40 family members of ICU patients concurred with Bond et al. findings.Families ‘need to know’ held top priority. The needfor information is a common thread as well in car-ing for rural families.  Hunsucker et al. (1999)  es-tablished that communication with the healthcareteam ranked one of the top ten priorities of thesefamilies. The need for daily information resoundedwith utmost importance. Updates given to them bythe family member’s physician was especially val-ued.

    Waters (1999)   compared differences in familymembers expectations across cultures of antici-pated professional nursing support expected dur-ing critical illness. Whites, Hispanics, and African

    Americans, 30 from each cultural group, partic-ipated in the quantitative comparison study. Re-sults confirmed that critical illness produced familystress responses across cultures. However, expec-tations of nurse caring behaviours were culturallyvaried. Hispanics and African Americans held higherexpectations of critical care nurses than did Whites.Providing information and keeping the family up-dated on physical changes were the expected be-haviours noted most frequently in all three culturalgroups.

    Family integration into ICU

    Families, as a rule, being secondary to patients, donot always find easy entry into ICUs. Hupcey (1999)explored integration of the family into the ICU. Inthis process, while the intention of the nurse andfamily is to support the patient through the illnessexperience, there is competition exhibited by theiractions as nurses look out for themselves and seekto maintain control over the family. For the fami-lies, looking out for themselves entailed ‘enduring’and trying to ‘find a niche’ in the ICU while being

    ‘on guard’ to protect the family member who couldnot fend for himself. Some families never movedbeyond ‘staying on guard.’

    In order to overcome objection and fit the fam-ily into the ICU, creation of a family-centred criti-cal care environment is paramount. Henneman andCardin (2002),  speaking for the American Associa-tion of Critical-Care Nurses (AACN), explained thatfamily-focused care is more than theoretical andmust entail commitment to the philosophy as wellas a thorough understanding of a family-centred ap-proach to care. In addition, the domain of nursing

    need not go it alone but rather in a spirit of co-operation and collaboration with other disciplinesfor successful implementation of an approach tocare that is not yet widely accepted. Henneman andCardin acknowledged that the patient is always thepriority; family-centred care just goes a step be-yond by including those persons significant to thepatient.

    Nursing interventions to ease the transition

    Interventions that go a step beyond to ease familystress, assist the integration process of the fam-ily into the critical care environment, and modifythe nursing focus to include the family offer a be-ginning point in establishing optimal family func-tioning. Leske (2002) examined practice protocolsbased on identified family needs to decrease anxi-

    ety. The research-based protocols of the AmericanAssociation of Critical-Care Nurses address familyneeds and anticipated outcomes as a result of spe-cific actions and behaviours on the part of nursing.

    In addition to practice protocols, instituting for-mal staff education programs have had positive ef-fects on both patients and nurses. Implementinga caring model designed to highlight caring be-haviours enhanced not only patient perception of caring behaviours but also satisfaction with care(Dingman et al., 1999; Yeakel et al., 2003). Partici-pation in a program designed to develop emotional

    self-control and improve communication skills en-hanced nurses’ competence and perceived commu-nication abilities (Garcia de Lucio et al., 2000).Nurses simultaneously felt less anxiety in deal-ing with families of critically ill patients whileexperiencing the perceived ability to empathizeand listen. The patients benefited by having amore relaxed nurse, and one more confidant innurse/family interactions.

    A further intervention, a supervised focus-groupprogram utilizing patient narratives, helped nursesthrough reflection on patient needs and the conse-quences of their actions toward the family. Nurse

    sensitivity and self-insight increased as a resultof reflection. Nurses increased their awareness of family needs and became more in touch with whatthe family was feeling. Nurses listened to how theytalked to families and in doing so, became moretherapeutic. Enhanced self-image, pride in the pro-fession, self-assurance and increased readiness forthe professional role stemmed from the group re-flection intervention (Lantz and Severinsson, 2001).

    Along with reflection and formal education pro-grams that increase therapeutic use of self, nursescan create an environment of care for families

    that involves other consults on the healthcare team(Henneman and Cardin, 2002). Nursing’s role is lim-ited; meeting family needs requires a multidisci-plinary team approach. Referrals including socialworkers, volunteers, and family advocates supportnursings’ efforts in gathering resources for the pa-tient and family.

    Appleyard et al. (2002) explored a nurse-coachedintervention through which family found comfort asthey sat in the waiting room when their need forinformation was met. In this intervention, nursesacted as preceptors to volunteers who manned thecritical care waiting room and acted as liaisons be-tween staff nurse and patient. Volunteers provideda human connection to their family member. Fam-ilies reported feeling less anxious and better in-formed as a result.

    An alternative program designed especially forfamilies of critical care patients in helping to bridge

    the communication gap, utilised a family advocate,one who is trained in crisis interventions, to meetfamily psychosocial needs and improve customersatisfaction (Washington, 2001). Because communi-cation is so vital, keeping the family informed andimproving communication with the family and theother professional team members are essential el-ements of the family advocate role.

    Exclusion of family during critical care hos-pitalisation intensifies their anxiety, stress andaffects family functioning. Family inclusion andparticipation in daily rounds in a Level 1 trauma

    centre successfully addressed family need for in-volvement, information, and communication withthe healthcare team (Schiller and Anderson, 2003).Since 2000, families have been included in dailytrauma rounds at Southern Illinois Trauma Centerin the USA. Families are allotted time to ask ques-tions, and are updated on the plan of care. Surveyfeedback thus far has been positive, documentingimproved communication, better understanding of the family member’s medical condition, and an in-creased sense of satisfaction with care.

    Conclusion

    Evidence obtained through reviews of both quan-titative and qualitative nursing research suggestthat nurse caring behaviours influence patient andfamily satisfaction with care and the family stressresponses associated with hospitalisation of a fam-ily member. Incongruence and lack of consensuson the part of the family and the nurse relevantto caring behaviours are also evident throughoutthe nursing research. ICU nurses are positioned to

    positively influence family stress responses throughinterventions geared specifically toward meetingfamily needs.

    This review of nursing literature has sought tobring to the forefront, the stress of the family andthe potential of the nurse, to assist families throughthe stress associated with critical illness or trauma.The initial step involves inclusion of the family intothe circle of care. Treatment of the family as part-ners in care, and a family-centred approach to careadditionally serve to alter stress responses. Nursecaring behaviours, employing an appropriate mixof skills, knowledge, and caring attitudes influencefamily stress responses associated with critical ill-ness or injury of a family member.
