Substance dependency in Iranian patients with hemophilia

AIMS

The prevalence and predisposing factors of substance dependency in 100 Iranian hemophilic patients were investigated.

MEASUREMENTS

A confidential questionnaire and DSM-IV criteria were used. Data were gathered from 100 randomly selected hemophilic patients.

RESULTS

The mean age of studied patients was 23.42+/-9.67 years, ranging from 12 to 74 years. The rate of substance dependency was high in hemophilic patients (39%), particularly while comparing with normal population. Prevalence of substance dependency was significantly related to age, marital status, number of family members, and being another substance-dependent in the family. Intensity of disease and its associated physical problems were not the main factors moving the patients toward substance dependency. Release of tension and enjoyment were the leading reasons for substance dependency. The nicotine was the most prevalent form of used substance.

CONCLUSIONS

The high rate of substance dependency among Iranian hemophilic patients is expected due to the characteristics of disease, loss of psychiatric supports and treatment facilities and the geographic locality of the country.

How well does the Canadian Haemophilia Outcomes-Kids' Life Assessment Tool (CHO-KLAT) measure the quality of life of boys with haemophilia?

BACKGROUND

It is important to measure the quality of life (QoL) of boys with haemophilia, because the diagnosis has a significant impact on their lives and this impact fluctuates over time. A disease-specific measure of QoL is required because the aspects of life that are affected by haemophilia may differ from those assessed by generic QoL measures. This paper describes the final phase of development of a disease-specific measure of QoL for boys with haemophilia: the Canadian Haemophilia Outcomes-Kids Life Assessment Tool (CHO-KLAT).

PROCEDURE

A 79-item version of the CHO-KLAT was administered to 52 children. A detailed item analysis was conducted to shorten the CHO-KLAT. The reliability of the revised version was assessed using intraclass correlation coefficients. Validity was assessed by comparing it to the PedsQL and the HaemoQoL.

RESULTS

The item analysis resulted in the retention of 35 strongly performing items (CHO-KLAT(35)). These items were aggregated into the CHO-KLAT(35) summary score. Repeated measures reliability of the CHO-KLAT(35) was 0.74 for children and 0.83 for parents, and the child-parent concordance was 0.75. The validity of the CHO-KLAT(35) was confirmed by a correlation of 0.78 with the Haemo-QoL and of 0.59 with the PedsQL.

CONCLUSIONS

The CHO-KLAT(35) is a reliable and valid measure of QoL for boys with haemophilia.

The Haemo-QoL Index: developing a short measure for health-related quality of life assessment in children and adolescents with haemophilia

As quality of life (QoL) research is increasingly focusing on children and adolescents with haemophilia, the need for both age-appropriate and disease-specific assessment tools becomes apparent. Therefore, a set of questionnaires measuring QoL in children and adolescents with haemophilia was simultaneously developed in six languages within the European Haemo-QoL project (Haemophilia, 8, 2002, 47; Haemophilia, 10, 2004, 17). For implementation in larger studies and for use in daily clinical routine, a both short and psychometrically robust version of the questionnaire is needed. Using from the Haemo-QoL field study complete data sets of 306 children and adolescents (4-16 years) and their parents, a multivariate approach of item selection was applied to construct an eight-item instrument, the Haemo-QoL Index. The instrument is applicable to different age groups and represents the core content as well as the multidimensional structure of the original long versions. According to preliminary analyses, the index's psychometric performance concerning reliability and convergent validity is good. Further validation of the instrument's performance on a new and independent sample is needed.

[Effects of a self-help group program for young adults with hemophilia]

PURPOSE

The purpose of this study was to identify the effects of Self-help program for Young adults with hemophilia.

METHOD

A quasi-experimental design was used. The subjects were 40 young adults with hemophilia, 21 in the experimental group and 19 in the control group. The subjects of the experimental group participated in a self-help group program for five sessions for 5 weeks. The program consisted of health education about hemophilia, exercise, and therapeutic recreation. Its outcomes were evaluated on self-efficacy, ADL, depression, and quality of life. The obtained data was analyzed using the Mann-Whitney U test of SPSS.

RESULT

1) The scores of self-efficacy, ADL and quality of life increased significantly in the experimental group as compared to the control group. 2) The score of depression decreased significantly in the experimental group as compared to the control group.

CONCLUSION

Considering these research results, the program is effective in improving self-management ability and quality of life. Therefore this program could be implemented as a self-help group program for hemophilia clients.

Experiences of college-age youths in families with a recessive genetic condition

Growing up in a family with a recessive genetic condition can trigger questions about progeny effect. This study explored perceptions of family hardiness and information sharing by 18- to 21-year-olds about genetic risk. Semistructured interviews, the Family Hardiness Index (FHI), and a Family Information Sharing Analog Scale (FISAS) were used. Participants included 11 youths who had relatives with hemophilia and 4 with sickle cell anemia. Findings revealed seven themes: assimilating premature knowledge; caring for others, denying self; cautioning during development; experiencing continual sickness; feeling less than; magnifying transition experiences; and sustaining by faith. There was no significant correlation between total FHI and FISAS. However, there was a statistically significant difference in FISAS between genetic condition variance. Specifically, higher hardiness was found and information sharing correlated among college youths in families with hemophilia. Additional research can lead to nursing interventions to provide genetic information to youths in families for illness variance.

The best experts: the narratives of those who have a genetic condition

In recent years, there have been growing expectations about the future benefits deriving from the uptake of genetics knowledge in healthcare. At the same time, there have been increasing calls to make greater use of patient expertise in treatment. However, relatively little is known about the experiences, needs and expertise of those who currently have a genetic condition. Drawing on the findings from an Australian study involving 21 semi-structured interviews with members of support groups which represent those with various genetic conditions (cystic fibrosis, haemochromatosis, haemophilia, and thalassaemia) this article discusses how individuals learn about, live with and manage their condition, and assesses the extent to which their experiences differ from those with other chronic illness conditions. It argues that while the experiences of individuals who have a genetic condition would appear to be similar in many respects to those with other chronic illnesses, they tend to encounter particular challenges in managing their condition due to its inheritable nature.

Compliance with treatment and understanding of own disease in patients with severe and moderate haemophilia

It is well known that teenagers with chronic diseases have problems complying with their treatment. The aim of this study was to evaluate the patient's knowledge of haemophilia and his compliance to prophylactic treatment, and the age at which the patient took over the responsibility for his disease and to create educational material for teenagers and adolescents. This was a prospective multicentre study performed in Hemophilia Treatment Centres in Scandinavia. A total of 108 of 134 patients, between 13 and 25 years completed the questionnaire, a response rate of 80%. Eighty-three patients had a severe form of haemophilia, 24 patients in moderate form and one patient did not know the severity of his disease. Seventy-eight patients were on prophylactic treatment. The median age for starting prophylactic treatment was 3.0 years and the median age for the patient performing venepuncture was 11.6 years. Sixty-seven of 78 patients knew that the best time to give prophylactic treatment was in the morning. Even though the patients were on prophylactic treatment, 47 of 78 patients took additional treatment before sports activities. At a mean age of 14.1 years the patient himself had the responsibility for his disease and treatment. In the cohort of 108 patients, 73 were aware of their haemophilia heredity. This study shows a rather high degree of knowledge of haemophilia and compliance with treatment among the patients but it is of great importance for the nurse to continuously improve the patient's compliance and keep him aware of the benefit of regular treatment for his future well being.

Funcionamiento social en niños hemofílicos: Análisis de encuesta para determinar factores psicopatológicos de riesgo

BACKGROUND

Children with hemophilia can experience problems with their mental health status and social functioning.

AIM

To assess the mental health status of hemophilic children.

MATERIAL AND METHODS

Thirty four hemophilic children aged 5 to 13 years were studied. A translation of the special survey to assess mental health in children, denominated "Domingo" Mental Health Survey was applied. It consisted in animated cartoon questions related to the family, social and school life. According to the score obtained, children were classified as normal, doubtful or pathologic. The social functioning areas studied were family, school, relationship and emotional. Aggressiveness, depression/anxiety and rejection were the psychopathologic factors analyzed.

RESULTS

Forty four percent of hemophilic children were considered normal, 20% doubtful and 35% pathologic. According to the severity of the disease, 67% of children with severe, 57% with moderate and 45% with mild hemophilia, were considered abnormal. Aggressiveness was the main risk factor in the emotional and family area, depression/anxiety in the family and emotional area and rejection in the family area. Fifty six percent of children had abnormalities in their social functioning and the severity of the disease was a predisposing factor.

CONCLUSIONS

Psychopathologic factors in children with hemophilia appear mainly in the family environment.

Differences between patients', physicians' and pharmacists' preferences for treatment products in haemophilia: a discrete choice experiment

The provision of health care to patients with haemophilia through replacement of the deficient coagulation factor is the result of a complex interaction between patients, physicians and policy makers, each carrying their individual sets of preferences. Preferences of patients, physicians and pharmacists towards perceived viral safety, risk of inhibitor development, infusion frequency during prophylaxis, pharmaceutical dosage form, distribution modes and price were evaluated by conjoint analysis, using a discrete choice experiment. Overall 178 patients', 69 physicians and 58 pharmacists completed the study. Patients, physicians and pharmacists displayed preferences: (i) similar in direction and strength for risk of inhibitors and frequency of prophylaxis, (ii) similar in direction, but not in strength for perceived viral safety and price, with patients showing lower strength compared with physicians and pharmacists, and (iii) dissimilar in direction and/or strength for: (i) dosage form, which tested important only for pharmacists and (ii) distribution mode, which tested important for patients and physicians only. Our study provides evidence of the differences between different stakeholders in the preferences towards haemophilia replacement therapy, indicating that different opinions should be taken into account when planning optimal care.

Handheld computers and paper diaries for documenting the use of factor concentrates used in haemophilia home therapy: a qualitative study

A recently published randomized controlled trial (RCT) showed that adherence to infusion diary record keeping was improved by the use of handheld computers. In this study, attitudes to record keeping were explored and patient preferences regarding the method of recording determined for the patients who participated in the trial. Qualitative study consisting of individual semi-structured interviews with 20 severely affected patients with haemophilia who participated in an RCT. Individuals were purposefully sampled based on their recent method of record keeping and whether child or adult. Analysis employed a constant comparative method to identify key themes from the data. Most individuals (19 of 20, 95%) considered record keeping to be important. They readily identified reasons to keep records: to benefit themselves, their families, clinical staff, product distributors and manufacturers. Keeping records helps them: feel a part of the health care team; have confidence they would be notified of product recalls; review their past history; improve their ability to advocate for themselves and improve communication among all parties. Record keeping, particularly when using paper diaries, can be burdensome and a challenge to maintain consistently. All 10 individuals (100%) who had used both paper diaries and handheld computers preferred the latter. Most patients understand that record keeping can be of benefit to them. Clinics can use this knowledge to inspire other patients by developing educational programmes that de-emphasize authority. In addition, given the evidence of both patients' preference for handheld computers, and the effectiveness of this approach documented in an RCT, switching to handheld computers is likely to improve record keeping.

An exploration of health-related quality of life in adults with haemophilia--a qualitative perspective

Musculoskeletal dysfunction is a common feature of haemophilia and along with other manifestations of this condition, there is a general perception that health-related quality of life (QoL) will be affected. Previous research using standardized questionnaires has demonstrated that QoL is lower in haemophilia groups compared with normal populations. However, disability studies and interviews with disabled people suggest that many disabled people experience positive life changes as a result of their illness and an affirmative model of disability has been proposed. A qualitative study involving focus groups and interviews was undertaken to explore these issues in a group of 19 severely affected adults with haemophilia. The focus groups and interviews were tape recorded and fully transcribed and the results subjected to thematic analysis. This paper focuses specifically on key issues that impacted on perceptions of QoL. The findings suggest that the participants' perceptions of their QoL were very positive. Possible reasons for this are proposed including the benefits of factor replacement, participants' recollections of their lifestyle before factor replacement, that having haemophilia was integral to the 'self' and finding a niche where they could be successful. A more positive affirmation of haemophilia may need to be considered when developing QoL measures.

Hepatitis C and health-related quality of life among patients with hemophilia

Hepatitis C has a negative effect on health-related quality of life (HRQoL). It is not clear whether hepatitis C affects HRQoL of patients with hemophilia. The objective of this study was to assess the effect of hepatitis C virus (HCV) infection on HRQoL in patients with hemophilia. A cross-sectional study was performed among all registered hemophilia patients in the Netherlands. HRQoL was determined by using the self-administered SF-36 questionnaire. Patients were eligible for the study if they completed the SF-36, had been treated with clotting factor products before 1992, and had reported their hepatitis C status. Data on the severity of hemophilia were obtained from the hemophilia treatment centers. The validity of the self-reported data on hepatitis C status was verified in a random sample of 92 (15%) patients; 92% reported their hepatitis C status correctly. Fifty-five percent (333/602) of the study population had a current HCV infection. All eight domains of the SF-36 were lower in patients with a current HCV infection than they were in patients who had never been infected with HCV. After adjustment for age, severity of hemophilia, human immunodeficiency virus (HIV) status, employment status, and joint limitations, hepatitis C infection was associated with a decrease of HRQoL on the domains of general health (difference 6.9 [95% confidence interval (C.I.) 2.7 to 11.2]) and vitality (3.8 [95% C.I. 0.1 to 7.7]). Hemophilia patients infected with HCV scored lower on the HRQoL domains of general health and vitality than hemophilia patients who had never been infected with HCV.

Measuring health state preferences for hemophilia: development of a disease-specific utility instrument

Generic and disease-specific instruments have been used to assess health-related quality of life (HRQoL) in hemophilia. However, HRQoL measures also need to reflect patient preferences for various hemophilia health states. The goal of this project was to develop a disease-specific utility instrument that measures patient preferences for various health states unique to hemophilia. The visual analog scale (VAS) and the standard gamble (SG) methods were used. Study participants (n = 128) were tested and stratified into paediatric and adult groups. Test-retest reliability was demonstrated for both instruments, with r = 0.91 for the VAS and r = 0.79 for the SG. When comparing results by age group, statistically significant differences were observed between paediatric and adult participants with the SG instrument (P = 0.045), with older participants taking more risk overall. However, no significant differences based on age were seen when using the VAS (P = 0.636). Statistically significant differences were observed between the VAS and SG instruments within both the paediatric and adult groups (P < 0.0001). In general, the SG yielded higher preference scores than the VAS for the majority of health states. Results derived from the SG instrument indicate that age can influence patients' preferences regarding their state of health. This can have implications for considering treatment options based on the mean age of the population under consideration. Both instruments demonstrated reliability and validity indicating that they could be used to assess patient preferences in hemophilia. However, preference score differences indicate that the two measures may not be interchangeable.

Effects of haemophilic arthropathy on health-related quality of life and socio-economic parameters

Although prophylactic treatment is advised for all children with severe haemophilia, the optimal regimen is still under discussion. Should all joint bleeds be prevented, or can a limited amount of arthropathy be tolerated in adulthood without loss of quality of life? To answer this question, the effect of haemophilic arthropathy on health-related quality of life (HRQoL) needs to be quantified. In a retrospective study, the effect of arthropathy on HRQoL and socio-economic parameters was assessed in a single-centre cohort of 96 patients with severe and moderate haemophilia with a minimum age of 13 years. Arthropathy was measured by the radiological Pettersson score of the elbows, knees and ankles (maximum: 78 points). HRQoL was assessed by the Short Form 36 (SF36), measuring eight domains of health. Labourforce participation and medical consumption were assessed using a separate questionnaire. Patients were studied at a mean age of 28.6 years (range: 13-54), the mean time between evaluation and the last Pettersson score was 0.4 years (SD: 1.1). The overall median Pettersson score was 13 (range: 0-78). There was a trend towards lower quality of life with increasing Pettersson scores and age, especially in the physical domains of the SF36. An age-adjusted analysis showed that arthropathy had a small but significant effect on HRQoL in the domain of 'physical function' of the SF36, but not on its other domains, or on labourforce participation and medical consumption. Thus suggesting that the SF36 can be used to assess the effects of haemophilic arthropathy, especially in the domain of 'physical function'.

Health-related quality of life (HRQL) scores reported from parents and their children with chronic illness differed depending on utility elicitation method

OBJECTIVE

To describe the relationship between health-related quality of life (HRQL) as measured by utility when elicited from parents and their children with chronic illness.

STUDY DESIGN AND SETTING

We enrolled families of children admitted for cancer chemotherapy and those attending outpatient rheumatology, hemophilia and bone marrow transplantation clinics. Children in grade 6 or higher were included. The child's HRQL was rated by parent and child using the Standard Gamble (SG), Visual Analogue Scale (VAS), Time Trade-Off (TTO), and Health Utilities Index Mark 2/3 (HUI2 and HUI3).

RESULTS

22 families were included. The mean parent SG was 0.92 +/- 0.09, which was similar to the mean SG elicited from their children of 0.92 +/- 0.10. The parent and child SG were moderately concordant (ICC=0.64, 95% CI=0.30, 0.83; P=.0005). In contrast, TTO scores were not concordant (ICC=0.14, 95% CI=-0.29, 0.53; P=.3), with parents (mean TTO=0.77 +/- 0.31) rating HRQL worse than children (mean TTO=0.92 +/- 0.11; P=.04). Similarly, the mean parent HUI2 of 0.82 +/- 0.22 was lower than the child HUI2 of 0.95 +/- 0.07; P=.02 and HUI2 were not concordant (ICC=0.11, 95% CI=-0.35, 0.53; P=.3) between parents and children.

CONCLUSION

Parents and children rate HRQL similarly according to SG, but parents rate HRQL significantly worse using TTO and HUI2.

Comparison of attitudes towards prenatal diagnosis and termination of pregnancy for haemophilia in Iran and Italy

Prenatal diagnosis (PND) is an important issue in the comprehensive care of haemophiliacs. As a consequence of technological progress made in the field of PND, the early detection of an affected fetus provides the expectant couple with a chance to terminate pregnancy. This study was undertaken to assess the attitudes of two different haemophilic populations in Iran and Italy towards PND and termination of pregnancy. This study series included 59 Iranians (38 haemophilia A patients and 21 mothers) and 50 Italians (27 haemophilia A patients, 16 mothers and seven fathers). All the 109 participants received a questionnaire including demographic characteristics and evaluating the psychological effects stemming from PND and termination of pregnancy. Approximately 84.7% of the Iranians and 35.4% of the Italians were not familiar with the possibilities afforded by PND for haemophilia (P < 0.001). Termination of pregnancy appeared to be accepted by 58.2% of the Iranian and 16.7% of the Italian participants (P < 0.001). The greater rate of acceptability of abortion in Iranians may be due to differences in the quality of patient care in the two countries.

Asking fathers: a study of psychosocial adaptation

Although few contemporary studies specifically address paternal adaptation, the theme of paternal estrangement from medical care and from family relationships is pervasive in the psychosocial literature on haemophilia. This estrangement has been shown to have a negative effect on fathers' psychological well-being, marital relationships and the adaptive outcome of their sons who have haemophilia. The goals of this study were to provide contemporary data on the psychosocial adaptation of fathers of boys with haemophilia and to examine specific variables that might influence their adjustment. Eighty-three eligible fathers returned a survey instrument that collected demographic and medical information, as well as scores on self-measures of adaptation in marital and parenting roles. Statistically significant direct correlations (P < 0.01) were found between fathers' scores on the Marital Adjustment Test and the Parenting Sense of Competence subscales (parenting efficacy and satisfaction). Variables specific to rearing a son with haemophilia that negatively affected fathers' marital adjustment scores included: feeling left out of medical decision making by their wives or partners, worry about their sons' having limited activity, and the presence of a secondary diagnosis in the affected child. Scores on the parenting efficacy subscale of the PSOC were statistically significantly reduced (i.e. fathers felt less effective in the parenting role) in men who 'rarely' or 'never' infused their sons (42/80, 53%). Variables that negatively affected scores on the parenting satisfaction subscale included frustrating interactions with medical staff and concern about their sons' potential to contract an infection or secondary diagnosis. This paper presents a model to examine the interrelationships among the data and discusses the clinical implications.
