Introduction

Despite improvements in health and medical sciences, the number of people suffering from renal failure has been steadily increasing worldwide, and accordingly the number of haemodialysis (HD) patients undergoing medical treatment has increased. For example, in Germany approximately 156 per million people develop end-stage renal disease each year, with prevalence slightly more than 700 per million [1].

Chronic illness affects not only the lives of those suffering from the disease, but also those family members who care for them [2]. Caregivers of patients with chronic disease are affected differently depending on the characteristics of the caregiver and the patient [3,4]. Family caregivers report missing work, taking personal days and quitting work or retiring early to provide care [5]. Caregiving is also an independent risk factor for higher levels of depression [6], anxiety and stress [7], mental disease, changes in family functioning [8] and mortality [9].

Studies of HD emphasize patient adaptation to dialysis, yet few studies deal directly with the spouse of the dialysis patient, who is intimately involved with the patient’s treatment [10]. Caregivers of HD patients may feel a heavy burden because they are obliged to play an important role in supporting patients on dialysis [11]. Depression in the caregivers of persons with multiple sclerosis was related to the physical, emotional and health status of the patients at baseline and/or at 12-months follow-up [12]. Caregivers of HD patients may experience a significant burden and an adverse effect on the emotional dimension of their quality of life (QOL). Therefore, social support and psychological interventions should be considered to improve caregivers’ lives and patients’ outcomes [13].

Ahmadi has developed a continuous care model for patients with coronary artery disease in the Islamic Republic of Iran (Figure 1) [14]. The aim was to establish and maintain a dynamic and continuous care relationship so as to raise awareness about the caring performance and to improve and promote the QOL of the clients. A continuous and effective care relationship isa dynamic, interactive and mutual relationship between the nurse and the patient and his/her family. In the development of such a relationship, both the quality of care and the content, method and nature of the services offered come to the fore. The continuous care model aims to be dynamic/flexible, client/family-oriented, empowering/self-enabling, holistic and collaborative.

In view of the importance of QOL for HD patients, this research aimed to study the effects of applying a continuous care model on the QOL of the spouses of HD patients.

Methods

Study design and sample

We carried out a quasi-experimental study from February to September 2005 of 36 spouses of HD patients in a referral dialysis centre in Hamadan, Islamic Republic of Iran. The participants were selected using simple randomized sampling; the inclusion criteria were the spouses of patients who had undergone HD for more than 6 months and who agreed to enter the study. The study was approved by the ethics committee of Hamedan University of Medical Sciences.

Data collection

Two questionnaires were used. The first collected the spouses’ characteristics, such as age, sex, number of family members, education, job, insurance cover and family income level (self-defined). The second was the Perceived Quality of Life (PQOL) questionnaire of Patrick et al. which was aimed at evaluating the QOL of the spouses. PQOL is a 20-item tool, with 19 items in 3 subscales (physical, social and cognitive health satisfaction), plus 1 item for rating happiness, a self-report measure that assesses satisfaction with the major categories of fundamental life needs and categories of functioning [15]. All items used a 0–10 scale (very dissatisfied/unhappy to very satisfied/happy). To measure the validity and reliability of the questionnaire, content validity and Cronbach alpha coefficient (α = 0.9) were assessed.

Before the intervention participants were familiarized with and briefed on the research goals and how to complete the questionnaires. They repeated the questionnaires 3 months after the intervention.

The intervention was carried out with 36 participants divided into 3 groups. The process proceeded in 4 phases: familiarization, sensitization, control and evaluation.

  • The familiarization phase aimed at an accurate diagnosis of problems with HD care, motivating the clients and determining their needs for the care process. The researchers coordinated a meeting which lasted 15–30 minutes during which the patient and his/her family were familiarized with the process, briefed on mutual expectations and advised about the continuation of the care–treatment relationship.
  • The sensitization process aimed to engage the patient and the family in the application of the continuous care approach. Negotiating this phase is critical to the success of the plan. The participants tok part in counselling sessions, group discussions, presentations and question-and-answer sessions (in 3 groups) about the nature and diversity of needs and problems facing the HD patient and his/her family to diagnose new problems, and to sensitize and motivate the clients to persevere with the process. There were 4–6 sessions lasting 1–2 hours. When the problem was not within the scope of the researchers’ knowledge and expertise, the patient and the family were referred to a specialist.
  • The remaining time was devoted to the continuation of the caring process (control phase), and weekly sessions were held with the participants. Problem checklists were completed regularly with the aim of reviewing and dealing with new care problems, considering the dynamic nature of health and disease, and starting the sensitization phase for new problems.
  • The fourth step was the evaluation, which continued throughout all stages of the model.

Analysis

The PQOL score was from 0–100 and categorized as: weak (score 0–33.3, average (score 33.4–66.6) and good (66.7–100). Descriptive, multiple regression and paired t-test statistical tests were used to analyse the collected data.

Results

There were 36 research participants: 50% were men; 41.7% were in the age range 40–59 years; 72.2% were illiterate or had only primary education; 44.4% were housewives and 66.7% reported their family income level as poor (Table 1).

Before the intervention, spouses’ scores in the PQOL were weak in the physical [mean 33.9; standard deviation (SD) 16.3] and cognitive (mean 12.7; SD 6.3) dimensions, but less so for social relations (mean 57.6; SD 26.7).

After the intervention there was a significant improvement in the mean scores for spouses’ QOL in all dimensions of the PQOL: physical (P = 0.0001), social (P = 0.0001) and cognitive (P = 0.0001) (Table 2). There was also a significant increase in the self-reported level of happiness experienced by spouses, from a mean score of 4.7 (SD 2.8) to 5.3 (SD 2.5) (P = 0.001) (Table 2). The mean total PQOL score increased significantly from 54.9 (SD 23.4) before to 64.8 (SD 21.9) after the intervention (P = 0.001) (Table 2).

Multiple regression analysis showed no significant difference (P < 0.05) in the QOL level (total and by dimension) perceived by the participants in relation to their individual characteristics (e.g. age, sex, income level, education level and job) (P < 0.05) (Table 3).

Discussion

Attending to the impact of chronic illness on family members is important because the physical and emotional health of family caregivers has the potential to influence the health, welfare and successful rehabilitation of persons with such illness [2].

Uncontrollable variables in this research were the clients’ knowledge, background, prior experience and interest in accepting the model and its details, and the mental and emotional status and cultural roots of the patients’ and their families’. Another limitation of the research was that the long-term effects of the process were not assessed.

Our findings show that before the intervention the QOL scores of spouses of HD patients were weak (except in social relations). However, the participants’ mean score of different dimensions of QOL and their total score of QOL increased significantly after the intervention. Therefore, it can be concluded that the application of the individual, group and family training in the continuous care model promoted improvements in the 3 dimensions of spouses’ QOL. Previous studies in the Islamic Republic of Iran showed that applying this caring model had significant effects on QOL of diabetic [15] and schizophrenic [16] patients.

Previous studies have documented how caring for chronically ill family members or significant others at home influences multiple aspects of caregivers’ lives. These effects may include worsened physical health, impaired social and family life, and increased stress, anxiety and depression. A study by Belasco and Sesso on the problems and QOL of the caregivers of HD patients showed that spouses caring for patients suffering from end-stage renal disease had a lower QOL than the general population and were adversely affected in physical dimensions, mental health and joviality [13]. Research by Campbell et al. on patients with prostrate cancer revealed that disorders in physical and psychosocial performance are an adverse side-effect of prostrate cancer treatment. Spouses/partners of patients often face multiple demands, including helping the patient cope with side-effects of treatment, such as erectile dysfunction and urinary incontinence, and providing support [17].

It is important to understand and distinguish between the attitudes, attributes and psychosocial characteristics of both patients and caregivers to plan and provide effective treatment interventions with the aim of improving the QOL for both groups [18].

In conclusion, applying a continuous care model to the care of patients undergoing HD makes a significant improvement to all areas of the spouses’ QOL.
