Summary

Most existing health-related quality of life research con-

cerns the impact of disease on patients. However, in several

medical specialties including dermatology, oncology, and

physical and mental disability, studies have been carried

out investigating the impact of disease on the lives of

families of patients. The aim of this paper is to review the

literature which relates to the impact of disease on family

members of patients. The OVIDSP Medline was selected as

the primary database, Searches were limited to sources

published in English. 158 papers were identified for

review. The definition of ‘‘family’’ varied across the litera-

ture, and a broad definition was accepted in this review.

This review shows that a wide variety of aspects of family

members’ lives can be affected, including emotional, finan-

cial, family relationships, education and work, leisure time,

and social activities. Many of these themes are linked to

one another, with themes including financial impact and

social impact being linked to emotional impact. Some posi-

tive aspects were also identified from the literature,

including family relationships growing stronger. Several

instruments exist to measure the impact of illness

on the family, and most are disease or specialty-

specific. The impact of disease on families of patients is

often unrecognised and underestimated. Taking into

account the quality of life of families as well as patients

can offer the clinician a unique insight into issues such

as family relationships and the effect of treatment

decisions on the patient’s close social group of partner

and family.

Introduction

Quality of life (QoL) of individuals is closely related to the QoL of those around them, includingpartners or parents1. Therefore, any chronic illness carries the potential to impact on the life of the family Compared to parents of healthy children, parents of children with chronic diseasereport lower self- development, restrictions on their well-being and emotional stability and lower levels of daily

functioning.2 Most studies on quality of life focus on assessing the quality of life of patients. Family quality of life has been explored in dermatology,3–9

oncology,10–21 and in the field of physical and mental disability,22–28 but little is known about the impact of disease on families of patients in many other specialties. Several key review articles have been writ- ten concerning the impact of illness on the quality of life of the partner,1 the impact of cancer on the family,14,19 the carer burden in mental health illness,22 the impact of chronic childhood illness on siblings,29 and the impact of chronic disease in the elderly on the patient’s family.30 Family members of patients are sometimes also carers, but those who do not act as carers are often still impacted. The aim of this paper is to review the literature relating to the impact of disease on all family members of patients, not just carers, and identify common themes. Instruments used to assess the quality of life of family members are also reviewed.

Methods

The OVIDSP Medline was selected as the primary database. This included the following resources: Cardiff University Books and Journals, PsycArticles, AMED (Allied and Complementary Medicine), British Nursing Index 1985-present, Embase 1947-present, HMIC (Health Management Information Consortium), ICONDA 1976 to June 2011, Medline In Process, Medline 1947-present, and PsycINFO 1806 to July Week 1 2011. A search of the Compendium of Quality of Life Instruments was also carried out.31,32 Searches were limited to sources published in English.

The main search term ‘‘family quality of life’’ was also substituted with ‘‘impact/effect on family’’, and ‘‘secondary impact’’, and these were combined with ‘‘disease’’ (Table 1). The term ‘‘partner’’ was also

used. ‘‘Impact on family’’ was combined with several common medical specialties. Each abstract identified was read to determine the type of study and its rele- vance. Where appropriate, the full paper was read in detail. To be included, a source had to be an original paper concerned with the impact of any illness or disability on the family of patients. Two measures of possible relevance to the impact of disease on family members of patients were identified.

Results

Search results

In total, 1517 abstracts were screened, and 158 were identified for review of the full paper. Of these, 63 articles highlighted at least one aspect which was not covered in other articles. Articles were rejected if, after fully reading them, their content was already covered by other articles. No sources were identified when combining the search term ‘‘impact on family’’ with several major medical specialties and only 13 sources were identified using the term ‘‘impact of dis- ease on family’’ (Table 1). Several sources were rejected for use of the term ‘‘family’’ in an irrelevant context, for example articles about genetics.

The majority of articles reviewed concerned family members of patients of one medical specialty or spe- cific disease, and were often limited to one particular family member, for example partners. No informa- tion was found regarding the more general impact of disease on families of patients over more than one specialty. However, many of the studies revealed similar ways that family members of patients were impacted by disease. In this review, only original art- icles were included.Table 2 summarises the studies which included a control group.

Definition of Family

The term ‘‘family’’ is difficult to define. The mid 20th century concept of family, with heterosexual parents and offspring living under the same roof is now seldom used, and many authors now consciously use a wider definition of family. The dynamics between family members are constantly evolving and there is evidence of many diverse family types in modern western European society33. Poston et al.34 define family as ‘‘people who think of them- selves as part of the family, whether by blood or mar- riage or not, and who support and care for each other on a regular basis’’, and this definition is thought to acknowledge the diverse social arrangements that may constitute a family.35 In other studies, the terms ‘‘family’’, ‘‘informal carer’’, and ‘‘carer’’ are used interchangeably.20,36 For this review, we have taken a broad view of the term family and accepted each authors interpretation as valid. Where studies refer to carers, it was ensured that this related to family carers.

Key impact areas

Most chronic diseases have similar effects on family members including psychological and emotional functioning, disruption of leisure activities, effect on

interpersonal relationships, and financial resources (Figure 1). However there may be some aspects which attain dominance in one particular disease as compared to other diseases. Several common themes were identified from the studies reviewed. Leisure and social impact were reported separately in much of the literature, and hence are reported as separate themes. Further examples of less common themes mentioned are summarised in Table 3.

Emotional impact

Family members suffer greatly from the emotional effects of living with, and caring for, a relative with a disease, with the impact of some diseases being felt by every member of the family.37 Emotional impact was the most common topic discussed in the litera- ture. The psychological distress felt by family mem- bers often results from their feelings of helplessness and lack of control.3,38 Many different emotions are mentioned by family members; guilt, anger, worry, upset, frustration, embarrassment, despair, loss, relief. Each emotion affects family members in differ- ent ways and to different extents, often depending on the disease severity of the patient,39,40 and the period of time that has passed since the diagnosis.13

Female partners of cancer patients had higher psy- chological distress than male partners.12 However, no significant difference was seen between genders when measuring overall quality of life of relatives.

There may be gender differences in responses to care- giving,16,19,41,42 although there was no difference in the well-being of partners of rheumatoid arthritis patients, based on the gender of the patient.43 It is not just the parents and partners who are affected emotionally by a relative’s disease.29 For example, siblings of children with pervasive developmental dis- order suffered from ‘‘significant adjustment prob- lems’’ compared to a control group.24

Financial impact

One of the greatest burdens on family members of patients is the financial cost to the family.44 This can include treatment costs, transport to appoint- ments, the cost of hiring a carer, and adapting their home environment. In a Canadian study,45 families spent on average C$624 per month on care or support for the patient with an intellectual disability; many described not having any money left at the end of the month. In a similar USA study, the financial impact on families caring for patients with dementia varied from US$3630 to US$17700 depending on the severity of the patient’s dementia.46

The financial strains felt by family members of patients often lead to stress and worry. Family mem- bers of dermatology patients increase their working hours in order to support their family financially, and many need state benefits to cover the extra costs which may lead to compromises for other family

members.3 When caring for a child with cerebral palsy, providing even the basic necessities put finan- cial pressure on the parents,47 and accessing funding was also challenging, which again increased stress and emotional effects. The difficulties involved in

accessing funding are greater in low income families, who often receive minimal support and face greater problems with social functioning and relationships.48

Impact on family relationships

Family members of patients experience a negative effect on their family relationships, both between the relative and the patient, and between other mem- bers of the family as a result of the patient’s illness. Poor family relationships do not bode well for chronic disease management regardless of the disease and often family members find relationships difficult as they do not know how to emotionally support each other.49 Family members of patients with multiple sclerosis reported negative effects on their relation- ships with each other, resulting in arguments, tension, and a lack of understanding of each other’s feelings.37

In particular, relatives struggle to deal with patients whose beliefs, outlook, and behaviour have altered as a consequence of their disease. There was little time for relationships between other members of the family. For example, Golics et al.50 found that 38% of adolescents with dermatological conditions felt that their family relationships had been affected as a result of their condition.

Partners of patients experience a negative effect on their sex lives as a result of the patient’s disease,often as a result of the patient’s symptoms51 or not having time to spend together as a couple due to another family member’s illness.3 It can lead to friction between couples, and in some cases can lead to the breakdown of relationships, or partners seeking sexual encounters outside the relationship.3,6

However, in some families relationships can grow stronger,52 as the family members work together to help each other and become more closely knit. In families with a child with an intellectual disability, the majority were taking the initiative to maintain good family relations, and engaging in family activ- ities to encourage this.45 An increase in family close- ness was also found in families of cancer survivors; one husband of a survivor said ‘‘I look at life differ- ently after that. I feel much closer to her.’’15

Education and work

Living with, or caring for, a relative with a disease can have a large impact on the education and careers of family members. This could include disruption of school work in siblings or children of the patients, or the employment of adults being affected and the burden of care placed upon them. Some families of children with disabilities45 felt that some of their family members would not be able to attend work or school in the near future. One family member is quoted: ‘‘The unpredictable natures of our children’s health and lives does not often fit with a typical, pro- gressive work profile’’.45 In eight of the 34 families studied, one or both parents had given up an educa- tion or career to care for their child with a disability. 40% of family members of dermatology patients felt that their employment was affected by their family member’s skin condition.3 Reasons included needing to look after the patient, attendinghospital appoint- ments, and emotional effects affecting work. Looking after a patient with cancer can also have a huge impact on a family member’s work on a day-to-day basis.20 Family member carers were reporting late for work, missing work, spending time at work talking on the telephone to their relative and some left work due to their carer responsibilities.

Leisure time

An important part of family QoL is family members being able to participate in the hobbies they enjoy.34

The barriers that prevent families from taking advan- tage of leisure opportunities45 link into other domains of family quality of life, including lack of time due to the responsibilities of care, limited finance, and lack

of support available. However, encouragingly, it has been shown that when family members do take the initiative to plan leisure activities, they usually work out positively, despite the restrictions due to the rela- tive’s illness, and families show high satisfaction with this achievement.45

Family members also find difficulty in taking family holidays, often depending on the disease state of their relative. Problems with finding suitable accommodation can make holiday planning ‘‘awk- ward’’.47 Relatives of patients with skin diseases described limitations of holiday planning, for exam- ple not wanting to swim together at the beach or their relative having to wear certain types of clothes.4

Social impact

The burden on family members caring for a person with a disease has a drastic effect on their social lives.3,4,34,47 Mothers caring for disabled children felt that their lives were so different from their friends and felt that they could only contribute to depressing conversations, and therefore lost friends as a result.47

Other family members described friends ‘‘drifting away’’, as they do not understand the family situation.37

A large number of individuals with a relative suf- fering from a skin disease complained of social dis- ruption.4 Conditions which result in visible signs of disease (for example basal cell carcinoma on the face or chronic obstructive pulmonary disease requiring oxygen therapy) may have a greater effect on the social lives of patients and their relatives, for fear of strangers’ reactions to their visible condition. Mothers of adolescent patients suffering from severe chronic pain reported more restrictions in their social life than mothers of children with less severe chronic pain and the authors suggest that this could be dir- ectly related to the illness.53

Instruments to measure family quality of life

Several studies have lead to the development of instruments designed to measure the impact of dis- ease on families of patients.3,26,54,55 However, these instruments are mostly disease or specialty specific, and can therefore only be used to assess the quality of life of the family of a particular group of patients.

The Family Dermatology Life Quality Index(FDLQI) is a ten-item questionnaire designed to measure the quality of life of family members of dermatology patients.56 This validated instrument contains items such as ‘‘Over the last month how much emotional distress have you experienced due to your relative/partner’s skin disease (e.g. worry,
