Economic and psychologic costs for maternal caregivers of gastrostomy-dependent children

Quality of life in paediatric gastrointestinal and liver disease: a systematic review

OBJECTIVES

To identify and appraise all studies relating to and instruments developed to measure quality of life (QOL) in children with gastrointestinal or liver diseases.

METHODS

A literature search was undertaken using MEDLINE, EMBASE, CINAHL, and PsycINFO to identify relevant articles published up to the end of 2005. These were reviewed by both authors and data were extracted using a standardised form. Articles were excluded if no attempt was made to measure QOL, they did not relate to children ages <17 years, they did not relate to gastrointestinal or liver diseases, or they were review articles. Quality of life instruments identified were rated according to proposed criteria.

RESULTS

From a total of 2379 articles identified in the initial search, a total of 2309 were excluded, leaving 70 included studies. These were assigned to the following categories: inflammatory bowel disease, n = 17; cystic fibrosis, n = 20; liver disease, n = 11; surgery, n = 15; and miscellaneous, n = 7. These studies describe the impact that these diseases have on the QOL of affected children. A total of 11 disease-specific QOL instruments and 1 generic instrument with a chronic disease module were identified, but only 5 of these fulfilled the proposed quality criteria and can be recommended for future use.

CONCLUSIONS

Chronic gastrointestinal and liver diseases can have an enormous effect on the QOL of affected individuals and their families. A number of disease-specific paediatric QOL instruments have been developed and validated. Quality of life is an important outcome that should be incorporated into clinical practice and measured when treatments are evaluated. Future research should explore how QOL can best be improved in children in whom it is severely impaired.

Caregiving time in sickle cell disease: psychological effects in maternal caregivers

BACKGROUND

Providing home care for a child with a chronic illness can be stressful for the family. The purpose of this paper is to examine patterns of caregiving and the associated psychological impact on maternal caregivers of children with sickle cell disease (SCD).

PROCEDURE

Fourteen maternal caregivers of children with SCD were interviewed as part of a larger study of maternal caregivers of children with chronic illness. Forty-four caregivers of children with HIV and 36 caregivers of healthy children were included as comparison groups. Interviews included questions regarding amount of time spent providing care for the child (technical care, non-technical care, health care management), hospitalization, emergency room visits, illness stigma, and mental health of the caregiver.

RESULTS

Children with SCD had significantly lower functional status and significantly more hospitalizations in the previous 3 months than children with HIV. Caregivers of children with SCD were more likely to work full-time and had higher incomes than caregivers of children with HIV. The three caregiving groups did not differ significantly on amount of total care, although caregivers of children with SCD and caregivers of children with HIV both reported significantly more time spent in technical care than caregivers of healthy children. Despite lower functional status of the children in the SCD group, when group comparisons on caregiving time variables were adjusted for child's functional status, the differences between groups increased. This appeared to be due to the fact that caregivers in the HIV group spent more time in all caregiving categories except skin, crisis, and other care. In terms of caregiver mental health, caregivers of children with HIV and SCD had significantly higher depressive mood scores than caregivers of healthy children but the groups did not differ on caregiving burden.

CONCLUSIONS

The perceived care burden of caregivers of children with SCD may be related to the unpredictable nature of the crisis care they provide. Additional attention is warranted to developing adequate resources for caregivers of children with SCD to mitigate the stress of unexpected crises.

Tube weaning according to the Graz model in two children with Alagille syndrome

Two children were weaned from long-term tube feeding after liver transplant because of Alagille syndrome. The children were successfully weaned, one in seven days and the other in 13 days, using our standard and highly specialized intensive treatment protocol. Normal feeding behavior and stabilization of body weight were established. Children fed by long-term enteral tubes can be weaned from enteral feeding even after a long period of treatment. The return to age-appropriate self-feeding should be introduced as early as possible. Our weaning program time is brief and effective and can be recommended generally to improve quality of life and withhold unintended side-effects of enteral nutrition.

Incorporating carer effects into economic evaluation

BACKGROUND

Despite great interest in the development of methods used in the economic evaluation of health technologies, the effects of carer costs and quality of life (QOL) on the cost effectiveness of treatments has not been widely explored. Yet carer effects are clearly evident in the literature and relevant to the perspective of many published economic evaluations.

OBJECTIVE

To examine whether patient QOL is associated with carer time and carer QOL.

METHODS

We used two datasets to investigate carer effects. Firstly, we used 40,312 cases from the Health Outcomes Data Repository (HODaR) to assess the relationship between patient utility, using the EuroQoL (EQ)-5D, and the number of days care needed from friends and relatives. The stability of the relationship across patient subgroups was assessed by replicating the analysis in ten disease groups. Secondly, we used 64 cases from a study of patients with Alzheimer's disease and their primary carer. These data allowed us to estimate the relationships between patient and carer utility, using the EQ-5D, and patient utility and carer burden using the Community Dementia Quality of Life Profile (CDQLP).

RESULTS

For carer time, a linear model showed that each 0.1-point reduction in patient utility was associated with a 2.5-day increase in carer time over a 6-week period. A more general model, based on EQ-5D domain scores, was better specified and showed that decreased functioning within each domain is associated with increased carer time. Problems with self-care and usual activities have the greatest impact on carer time. These models do not appear to be stable across different disease groups. For carer utility, the relationships between carer and patient utility have low explanatory power and are poorly specified. A clearer relationship is shown between carer burden and utility, such that when sociodemographic covariates are introduced, the relationship reaches conventional levels of statistical significance (p < 0.05).

CONCLUSIONS

The preliminary work described here shows that improving patient QOL may reduce the need for carer time and improve carer QOL. Incorporating such effects into economic evaluations will change cost-per-QALY estimates, with the size of reduction dependent on the domains of health affected by treatment. Clinical studies need to capture carer data so that we can better understand these effects, and how they impact on economic evaluation.
