Healthcare Utilization (healthcare + utilization)
Selected AbstractsHealthcare Utilization of Elderly Persons Hospitalized After a Noninjurious Fall in a Swiss Academic Medical CenterJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 6 2006Laurence Seematter-Bagnoud MD OBJECTIVES: To determine the risk of hospital readmission, nursing home admission, and death, as well as health services utilization over a 6-month follow-up, in community-dwelling elderly persons hospitalized after a noninjurious fall. DESIGN: Prospective cohort study with 6-month follow-up. SETTING: Swiss academic medical center. PARTICIPANTS: Six hundred ninety persons aged 75 and older hospitalized through the emergency department. MEASUREMENTS: Data on demographics and medical, physical, social, and mental status were collected upon admission. Follow-up data were collected from the state centralized billing system (hospital and nursing home admission) and proxies (death). RESULTS: Seventy patients (10%) were hospitalized after a noninjurious fall. Fallers had shorter hospital stays (median 4 vs 8 days, P<.001) and were more frequently discharged to rehabilitation or respite care than nonfallers. During follow-up, fallers were more likely to be institutionalized (adjusted hazard ratio=1.82, 95% confidence interval=1.03,3.19, P=.04) independent of comorbidity and functional and mental status. Overall institutional costs (averaged per day of follow-up) were similar for both groups ($138.5 vs $148.7, P=.66), but fallers had lower hospital costs and significantly higher rehabilitation and long-term care costs ($55.5 vs $24.1, P<.001), even after adjustment for comorbidity, living situation, and functional and cognitive status. CONCLUSION: Elderly patients hospitalized after a noninjurious fall were twice as likely to be institutionalized as those admitted for other medical conditions and had higher intermediate and long-term care services utilization during follow-up, independent of functional and health status. These results provide direction for interventions needed to delay or prevent institutionalization and reduce subsequent costs. [source] Health, Healthcare Utilization, and Satisfaction with Service: Barriers and Facilitators for Older Korean AmericansJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 9 2005Yuri Jang PhD The present study assessed predictive models of subjective perception of health, healthcare utilization (hospital visits), and satisfaction with healthcare service using a sample of 230 older Korean Americans. Predisposing characteristics (age, sex, and education), health needs (chronic conditions, functional disability, and number of sick days), and a variety of enabling factors (health insurance, English speaking ability, transportation, living arrangement, trust in Western medicine, and reported experience of disrespect in medical settings) were considered. After controlling for predisposing and need factors, health insurance coverage was found to be a significant enabling factor for hospital visits. Subjective perception of health was found to be significant not only for healthcare utilization, but also for satisfaction with service. A greater likelihood of satisfaction was also observed in individuals with health insurance, better English-speaking ability, and greater trust in Western medical care. The reported experience of disrespect or discrimination in medical settings significantly reduced the odds of satisfaction with service. [source] PROCEED: Prospective Obesity Cohort of Economic Evaluation and Determinants: baseline health and healthcare utilization of the US sample,DIABETES OBESITY & METABOLISM, Issue 12 2008A. M. Wolf Aim:, To summarize baseline characteristics, health conditions, resource utilization and resource cost for the US population for the 90-day period preceding enrolment, stratified by body mass index (BMI) and the presence of abdominal obesity (AO). Methods:, PROCEED (Prospective Obesity Cohort of Economic Evaluation and Determinants) is a multinational, prospective cohort of control (BMI 20,24.0 kg/m2), overweight (BMI 25,29.9 kg/m2) and obese (BMI , 30 kg/m2) subjects with AO and without AO [non-abdominal obesity (NAO)], defined by waist circumference (WC) >102 and 88 cm for males and females, respectively. Subjects were recruited from an Internet consumer panel. Outcomes were self-reported online. Self-reported anthropometric data were validated. Prevalence of conditions and utilization is presented by BMI class and AO within BMI class. Differences in prevalence and means were evaluated. Results:, A total of 1067 overweight [n = 474 (NAO: n = 254 and AO: n = 220)] and obese [n = 493 (NAO: n = 39 and AO: n = 454)] subjects and 100 controls were recruited. Self-reported weight (r = 0.92) and WC (r = 0.87) were correlated with measured assessments. Prevalence of symptoms was significantly higher in groups with higher BMI, as were hypertension (p < 0.0001), diabetes (p < 0.0001) and sleep apnoea (p < 0.0001). Metabolic risk factors increased with the BMI class. Among the overweight class, subjects with AO had significantly more reported respiratory, heart, nervous, skin and reproductive system symptoms. Overweight subjects with AO reported a significantly higher prevalence of diabetes (13%) compared with overweight subjects with NAO (7%, p = 0.04). Mean healthcare cost was significantly higher in the higher BMI classes [control ($456 ± 937) vs. overweight ($1084 ± 3531) and obese ($1186 ± 2808) (p < 0.0001)]. Conclusion:, An increasing gradient of symptoms, medical conditions, metabolic risk factors and healthcare utilization among those with a greater degree of obesity was observed. The independent effect of AO on health and healthcare utilization deserves further study with a larger sample size. [source] Lifetime depression and diabetes self-management in women with Type 2 diabetes: a case,control studyDIABETIC MEDICINE, Issue 6 2010J. A. Wagner Diabet. Med. 27, 713,717 (2010) Abstract Aims, Little is known about the association between lifetime history of major depressive disorder (L-MDD) and diabetes self-management, particularly when depression is remitted. We examined the association between L-MDD and diabetes self-management in women with Type 2 diabetes who were not depressed at the time of assessment. Methods, L-MDD was assessed with structured psychiatric interview. Participants completed paper-and-pencil measures of demographics, diabetes-related distress, self-care behaviours, healthcare utilization and diabetes self-efficacy. Results, One-hundred and fifty-three women participated; 41% had L-MDD. Compared with their never-depressed counterparts, women with L-MDD had more diabetes distress, reported lower overall rates of self-monitoring of blood glucose (SMBG) and greater tendency to skip SMBG, had lower diet adherence and were less likely to have seen a primary care provider in the past year. Diabetes self-efficacy mediated the relationship between L-MDD and self-management. Conclusions, Interventions to promote self-management for patients with L-MDD may be warranted. [source] Healthcare charges and utilization associated with diabetic neuropathy: impact of Type 1 diabetes and presence of other diabetes-related complications and comorbiditiesDIABETIC MEDICINE, Issue 1 2009Y. Zhao Abstract Aims The aim was to examine the impact of Type 1 diabetes and having any other diabetes-related complication or comorbidity on healthcare charges and utilization in patients with diabetic neuropathy (DN). Methods We selected individuals aged < 65 years who continuously enrolled in a large US commercial plan from July 2004 to June 2006 and who received at least one diagnosis of DN at any time from July 2004 to June 2005. We compared the prevalence of other diabetes-related complications or comorbidities between patients with Type 1 and with Type 2 diabetes. In patients with DN with or without any other diabetes-related complication or comorbidity, we used multivariate regression to assess the marginal contribution of Type 1 diabetes on healthcare charges and utilization from July 2005 until June 2006. Results The majority of DN patients had at least one other diabetes-related complication or comorbidity. Most of the DN patients had Type 2 diabetes. DN patients with Type 1 diabetes had more comorbid medical conditions than those with Type 2 diabetes. Compared with Type 2, Type 1 patients had a higher prevalence of each individual non-DN diabetes-related complication or comorbidity, except heart disease. Controlling for comorbidities, Type 1 and Type 2 patients with DN but no other diabetes-related complication or comorbidity had similar healthcare utilization. However, Type 1 patients had significantly higher charges than those with any other diabetes-related complication or comorbidity. Conclusions Many patients with DN have Type 1 diabetes and other common diabetes-related complications or comorbidities, which can have a significant impact on healthcare charges and utilization. [source] Physical inactivity and its impact on healthcare utilizationHEALTH ECONOMICS, Issue 8 2009Nazmi Sari Abstract Physically inactive people are expected to use more healthcare services than active people. This inactivity imposes costs on the collectively funded health insurance programs. In this paper, excess utilization of healthcare services due to physical inactivity is examined using count data models and the Canadian Community Health Survey. The aim of the paper is to estimate utilization of healthcare services associated with inactivity and to estimate its impact on the Canadian healthcare system. The results suggest that physical inactivity increases hospital stays, and use of physician and nurse services. On average, an inactive person spends 38% more days in hospital than an active person. S/he also uses 5.5% more family physician visits, 13% more specialist services, and 12% more nurse visits than an active individual. The subsequent social cost of inactivity for the healthcare system is substantial. Copyright © 2008 John Wiley & Sons, Ltd. [source] Psychological treatment may reduce the need for healthcare in patients with Crohn's disease,INFLAMMATORY BOWEL DISEASES, Issue 6 2007Hans-Christian Deter MD Abstract Background: Few published studies examine the influence of psychological treatment on health care utilization in Crohn's disease. Methods: The present substudy of a prospective, randomized, multicenter trial conducted in 69 of 488 consecutive Crohn's disease (CD) patients was designed to investigate the way in which healthcare utilization is influenced by psychotherapy and relaxation in addition to standardized glucocorticoid therapy. Before and after a 1-year period of standardized somatic treatment the psychotherapy and control groups were compared with regard to hospital and sick-leave days. Predictors of healthcare utilization were analyzed. Results: The comparison between groups before and after psychological treatment showed a significantly higher decrease of mean hospital days (P < 0.03) and sick-leave days in the treatment group compared with the controls. When a covariate analysis was applied to compare the data at randomization, the difference in hospital days remained statistically a trend (P < 0.1). Multivariate regression analysis detected a significant gender and depression effect for hospital days (cor r2 = 0.114) and a significant gender and age effect for sick-leave days (cor r2 = 0.112). Conclusion: A significant drop in healthcare utilization after psychological treatment demonstrates a clear benefit of this additional therapy. This is important, since the study failed to demonstrate significant changes in the psychosocial status or somatic course of study patients. Clinical and psychological factors influencing these outcomes are discussed. (Inflamm Bowel Dis 2007) [source] Patients presenting with somatic complaints: epidemiology, psychiatric co-morbidity and managementINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 1 2003Kurt Kroenke MD Abstract Somatic symptoms are the leading cause of outpatient medical visits and also the predominant reason why patients with common mental disorders such as depression and anxiety initially present in primary care. At least 33% of somatic symptoms are medically unexplained, and these symptoms are chronic or recurrent in 20% to 25% of patients. Unexplained or multiple somatic symptoms are strongly associated with coexisting depressive and anxiety disorders. Other predictors of psychiatric co-morbidity include recent stress, lower self-rated health and higher somatic symptom severity, as well as high healthcare utilization, difficult patient encounters as perceived by the physician, and chronic medical disorders. Antidepressants and cognitive-behavioural therapy are both effective for treatment of somatic symptoms, as well as for functional somatic syndromes such as irritable bowel syndrome, fibromyalgia, pain disorders, and chronic headache. A stepped care approach is described, which consists of three phases that may be useful in the care of patients with somatic symptoms. Copyright © 2003 Whurr Publishers Ltd.

(2009) Personal and social determinants of health services utilization by Mexican older people. International Journal of Older People Nursing 5, 193,201 doi: 10.1111/j.1748-3743.2009.00193.x Background., Increased healthcare needs among older individuals around the world demands a better understanding of factors influencing healthcare service utilization patterns. Objective., To examine personal and social correlates to health services utilization among Mexican older persons. Design and methods., This was a cross-sectional study conducted between 2004 and 2006 with 2030 Mexican adults 60 years and older and based on a health services utilization framework. A two-stage cluster sampling with probability proportionate to size was used. Participants were randomly selected and recruited in four metropolitan areas in Northeastern Mexico. Chi-square and Pearson's chi-squared tests and logistic regression were used for data analyses. Results., Significantly more women than men had lost a spouse and were illiterate. Also, females reported significantly poorer health, higher nutritional risk and lower ability to perform activities of daily and instrumental living than males. Predictors of healthcare utilization were: Having a caregiver during an illness; perceiving to have a health problem; being able to afford food, and having children. Conclusions., Predisposing, enabling and need factors are strong predictors of health services utilization among Mexican older persons. In addition, gender differences exist among this population in relation to health status, but not to health services demands. [source] Healthcare Cost Differences with Participation in a Community-Based Group Physical Activity Benefit for Medicare Managed Care Health Plan MembersJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 8 2008Ronald T. Ackermann MD OBJECTIVES: To determine whether participation in a physical activity benefit by Medicare managed care enrollees is associated with lower healthcare utilization and costs. DESIGN: Retrospective cohort study. SETTING: Medicare managed care. PARTICIPANTS: A cohort of 1,188 older adult health maintenance organization enrollees who participated at least once in the EnhanceFitness (EF) physical activity benefit and a matched group of enrollees who never used the program. MEASUREMENTS: Healthcare costs and utilization were estimated. Ordinary least squares regression was used, adjusting for demographics, comorbidity, indicators of preventive service use, and baseline utilization or cost. Robustness of findings was tested in sensitivity analyses involving continuous propensity score adjustment and generalized linear models with nonconstant variance assumptions. RESULTS: EF participants had similar total healthcare costs during Year 1 of the program, but during Year 2, adjusted total costs were $1,186 lower (P=.005) than for non-EF users. Differences were partially attributable to lower inpatient costs (,$3,384; P=.02), which did not result from high-cost outliers. Enrollees who attended EF an average of one visit or more per week had lower adjusted total healthcare costs in Year 1 (,$1,929; P<.001) and Year 2 (,$1,784; P<.001) than nonusers. CONCLUSION: Health plan coverage of a preventive physical activity benefit for seniors is a promising strategy to avoid significant healthcare costs in the short term. [source] Healthcare Costs and Utilization of Vulnerable Elderly People Reported to Adult Protective Services for Self-NeglectJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2008(See editorial comments by Dr. Mark Lachs, pp 757) OBJECTIVES: To assess differences between diagnoses, healthcare utilization, and healthcare costs of vulnerable elderly people reported to Adult Protective Services for self-neglect and those of matched controls. DESIGN: A case-control study of 131 self-neglect cases and 131 matched controls. SETTING: All participants were patients in a public hospital geriatrics program. PARTICIPANTS: Adult Protection Services referred the self-neglect cases to an interdisciplinary geriatric medicine team. The controls were patients who used the same source of geriatric medical services and were matched on race or ethnicity, sex, and age. MEASUREMENTS: Diagnoses, healthcare utilization, and Medicare reimbursable costs were compared in cases and controls for 1 year before and 1 year after the case medical referral. RESULTS: Mental disorders were diagnosed more frequently in the self-neglect group than in the control group. Self-neglecters had lower healthcare utilization and medical costs than controls in the year before the medical referral, but utilization and costs were similar in the two groups in the year after the referral. CONCLUSION: This study provides evidence that, once self-neglecters are brought into the healthcare system, they are no more expensive than other similar patients. This result has important public policy implications and fills an important gap, because there is no published literature describing the financial effect of self-neglect on the healthcare system.

[source] Hospice Usage by Minorities in the Last Year of Life: Results from the National Mortality Followback SurveyJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 7 2003K. Allen Greiner MD OBJECTIVES: To examine racial/ethnic variations in rates of hospice use in a national cohort and to identify individual characteristics associated with hospice use. DESIGN: Secondary analysis of the 1993 National Mortality Followback Survey (NMFS), a nationally obtained sample using death certificates and interviews with relatives (proxy respondents) to provide mortality, social, and economic data and information about healthcare utilization in the last year of life for 23,000 deceased individuals. SETTING: Hospice care. PARTICIPANTS: Individuals aged 15 and older who died in 1993. Subjects were included in this analysis if they died of nontraumatic causes (N = 11,291). MEASUREMENTS: Hospice use was dichotomized by proxy responses indicating use or nonuse of home or inpatient hospice services. The percentage of individuals using hospice services in the last year of life was calculated. RESULTS: Unadjusted bivariate results found that African Americans were less likely to use hospice than whites (odds ratio (OR) = 0.59; P < .001) and that those without a living will (LW) (OR = 0.23; P < .001) and without a cancer diagnosis (OR = 0.28; P < .001) were less likely to use hospice. The negative relationship between African Americans and hospice use was unaffected when controlled for sex, education, marital status, existence of a LW, income, and access to health care. Logistic models revealed that presence of a LW diminished the negative relationship between African Americans and hospice use, but the latter remained significant (OR = 0.83; P = .033). A subanalysis of subjects aged 55 and older showed a significant interaction between access to care and race/ethnicity with respect to hospice use (P = .044). Inclusion of income in this multivariable logistic model attenuated the relationship between African-American race/ethnicity and hospice use (OR = 0.77), and the difference between whites and African Americans became only marginally statistically significant (P = .060). CONCLUSION: In the 1993 NMFS, hospice use was negatively associated with African-American race/ethnicity independent of income and access to healthcare. The relationship is not independent of age, insurance type, or history of stroke. For subjects aged 55 and older, access to healthcare may be an important confounder of the negative relationship between African-American race/ethnicity and hospice use. Consistent with previous studies, this analysis found that African Americans were less likely to use LWs than whites. The reduced importance of African-American race/ethnicity on hospice use with the inclusion of presence of a LW in logistic models suggests that similar cultural processes may shape differences between African Americans and whites in advance care planning and hospice use. [source] Diagnosis and management of geriatric insomnia: A guide for nurse practitionersJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 12 2008MN (Nurse Practitioner), Preetha Krishnan RN Abstract Purpose: To discuss the assessment, diagnosis, and management of geriatric insomnia, a challenging clinical condition of older adults frequently seen by primary care providers. Data sources: Extensive literature review of the published research articles and textbooks. Conclusions: Complaints of insomnia among older adults are frequently ignored, considered a part of the normal aging process or viewed as a difficult to treat condition. Geriatric insomnia remains a challenge for primary care providers because of the lack of evidence-based clinical guidelines and limited treatment options available. Effective management of this condition is necessary for improved quality of life, which is a primary issue for the elderly and their families. Therefore, geriatric insomnia warrants thorough attention from the nurse practitioners (NPs) who provide care for older adults. Implications for practice: Undiagnosed or under treated insomnia can cause increased risk for falls, motor vehicle accidents, depression, and shorter survival. Insomniacs double their risk for cardiovascular disease, stroke, cancer, and suicide compared to their counterparts. Insomnia is also associated with increased healthcare utilization and institutionalization. NPs could play a central role in reducing the negative consequences of insomnia through a systematic approach for diagnosis, evaluation, and management. [source] Increased health costs from mandated Therapeutic Substitution of proton pump inhibitors in British ColumbiaALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 8 2009B. J. SKINNER Summary Background, In 2003, British Columbia's PharmaCare programme implemented a drug reimbursement policy called Therapeutic Substitution, which required patients with acid-related diseases, primarily gastro-oesophageal reflux disease (GERD), to make a medically unnecessary switch from their prescribed proton pump inhibitor (PPI) to the cheapest available brand name PPI (Pariet, rabeprazole sodium), comprising a different (nongeneric) chemical. Aim, To evaluate the independent effects of PPI Therapeutic Substitution on individual healthcare utilization among those complying with the policy. Methods, We used the BC Ministry of Health Services' individual-level linked data, allowing isolation of healthcare utilization for the entire population of PPI consumers from 2002 to 2005. Results, After controlling for individual case variation in age, gender and a proxy for pre-existing health status, regression analysis revealed statistically significant greater overall use of PPIs, physician services and hospital services independently associated with patients who complied with Therapeutic Substitution. Over the 3-year period 2003,2005, this represented net healthcare expenditures totalling approximately C$43.51 million (C$9.11 million in total PPI drug expenditures, C$24.65 million for physician services and C$9.75 million for hospital services). Conclusion, Medically unnecessary drug switching caused by compliance with Therapeutic Substitution policy appears to be independently associated with higher overall healthcare utilization. [source] Relation between inflammation and symptoms in asthmaALLERGY, Issue 3 2009I. Tillie-Leblond Asthma symptoms are the main reason for healthcare utilization and are a fundamental parameter for the evaluation of asthma control. Currently, asthma is defined as a chronic inflammatory disease. A French expert group studied the association between inflammation and asthma symptoms by carrying out a critical review of the international literature. Uncontrolled asthmatics have an increased number of polynuclear eosinophils in the induced sputum and an increased production of exhaled NO. Control by anti-inflammatory treatment is accompanied by a reduction in bronchial eosinophilia and exhaled NO. Asthma symptoms are the result of complex mechanisms and many factors modify their perception. Experimental data suggest that there is a relationship between the perception of symptoms and eosinophilic inflammation and that inhaled corticoid therapy improves this perception. Although they are still not applicable in routine practice, follow-up strategies based on the evaluation of inflammation are thought to be more effective in reducing exacerbations than those usually recommended based on symptoms and sequential analysis of respiratory function. Inhaled corticosteroid therapy is the reference disease-modifying therapy for persistent asthma. Recent studies demonstrated that adjustment of anti-inflammatory treatment based on symptoms is an effective strategy to prevent exacerbations and reduce the total number of doses of inhaled corticosteroids. [source] Prevalence and cost of medication nonadherence in Parkinson's disease: Evidence from administrative claims data,MOVEMENT DISORDERS, Issue 4 2010Keith L. Davis MA Abstract We estimated the prevalence of medication nonadherence in Parkinson's disease (PD) and the association between treatment nonadherence and healthcare costs. Insurance claims from over 30 US health plans were analyzed. Inclusion criteria were as follows: PD diagnosis, ,1 PD-related prescription between 1/1/1997 and 12/31/2004, continuous health plan enrollment for ,6 months before and ,12 months after first PD prescription. Adherence, all-cause healthcare utilization, and all-cause costs were evaluated over 12 months post-treatment initiation. Adherence was measured using the medication possession ratio (MPR), with MPR < 0.8 defining nonadherence. Among patients identified for inclusion (N = 3,119), 58% were male and mean age was 69 years. Mean MPR was 0.58 and 61% of patients were nonadherent. Unadjusted mean medical costs were significantly higher (P < 0.01) among nonadherers ($15,826) compared with adherers ($9,228), although nonadherers had lower prescription drug costs ($2,684 vs. $3,854; P < 0.05). After controlling for confounders in multivariable analyses, a large positive relationship between nonadherence and both medical and total healthcare costs remained (+$3,451, P < 0.0001 and +$2,383, P = 0.0053, respectively). Medication adherence in PD is suboptimal and nonadherence may be associated with increased healthcare costs despite offsets from reduced drug intake. Efforts to promote medication adherence in PD may lead to cost savings for managed care systems. © 2010 Movement Disorder Society [source] The challenge of cross-cultural, multi-national research: potential benefits in the functional gastrointestinal disordersNEUROGASTROENTEROLOGY & MOTILITY, Issue 4 2009A. D. Sperber Abstract, The increasing interest in research in irritable bowel syndrome (IBS) and other functional gastrointestinal disorders (FGIDs), taken together with the growing sophistication of communication technology, makes cross-cultural, multi-national research a feasible endeavour. The aim of this study is to encourage collaborative cross-cultural studies in FGIDs by discussing relevant methodological issues, and by suggesting potential areas in which cross-cultural research can make a significant contribution to the understanding of FGIDs and to patient care. To this end, methodological issues related to cross-cultural research and competences required for its conduct are presented together with a critique of published studies and recommendations for future research in the area. The term ,cross-cultural' research in FGIDs is usually applied to the results of prevalence studies, for example comparative studies of IBS prevalence in different countries and ethnic groups. The validity of these comparisons is impacted negatively by the lack of uniformity in research methods. In addition to prevalence studies, cross-cultural research can make a significant contribution in areas such as molecular biology, genetics, psychosocial factors, symptom presentation, extra-intestinal comorbidity, diagnosis and treatment, determinants of disease severity, healthcare utilization, and health-related quality of life, all issues that can be affected by culture, ethnicity and race. Well-designed and implemented cross-cultural studies can advance our knowledge in many FGID-related areas ranging from epidemiology through psychosocial factors, pathophysiological mechanisms and therapeutics. These studies, conducted by investigators with competence in cross-cultural research methodology, can advance our understanding of the FGIDs and contribute to improved patient care. [source] A systematic review of psychological interventions for children with asthmaPEDIATRIC PULMONOLOGY, Issue 2 2007Grad., Janelle Yorke MSc Abstract Aim: Psychological factors may influence the symptoms and management of asthma in children in many ways. It is, therefore, suggested that psychological interventions may be appropriate for this population. This paper reports a systematic review assessing the efficacy of psychological interventions in improving health outcomes for children with asthma. Methodology: A review of Randomized Controlled Trials (RCT) was designed. RCTs assessing the effects of a psychological intervention in child participants were included in the review. Outcome measures included healthcare utilization, lung function, asthma symptoms, and psychological health status. The search was conducted until April 2005. Results: Twelve studies, involving 588 children, were included in the review; however, study quality was poor and sample sizes were frequently small. A meta-analysis was performed on two studies, examining the effects of relaxation therapy on PEFR which favored the treatment group (SD 0.82, CI 0.41,1.24). No other meta-analysis could be performed due to the diversity of interventions and the outcomes assessed. In addition, many studies reported insufficient data. Conclusions: This review was unable to draw firm conclusions for the role of psychological interventions for children with asthma. We recommend that valid outcome measures for evaluating the effectiveness of psychological interventions for children with asthma need to address adjustment to and coping with asthma, as well as other psychological indicators. The absence of an adequate evidence base is demonstrated, highlighting the need for well-conducted RCTs in this area. Pediatr Pulmonol. 2007; 42:114,124. © 2006 Wiley-Liss, Inc.

VarniJ. W., LimbersC. A. & BurwinkleT. M. ( 2007 ) Health and Quality of Life Outcomes , 5 , 2 . DOI:10.1186/1477-7525-5-2. Background, Health-related quality of life (HRQOL) measurement has emerged as an important health outcome in clinical trials, clinical practice improvement strategies, and healthcare services research and evaluation. While paediatric patient self-report should be considered the standard for measuring perceived HRQOL, there are circumstances when children are too young, too cognitively impaired, too ill or fatigued to complete an HRQOL instrument, and reliable and valid parent-proxy report instruments are needed in such cases. Further, it is typically parents' perceptions of their children's HRQOL that influences healthcare utilization. Data from the PedsQL DatabaseSM were utilized to test the reliability and validity of parent-proxy report at the individual age subgroup level for ages 2,16 years as recommended by recent Food and Drug Administration (FDA) guidelines. Methods, The sample analysed represents parent-proxy report age data on 13 878 children ages 2,16 years from the PedsQL 4.0 Generic Core Scales DatabaseSM. Parents were recruited from general paediatric clinics, sub-specialty clinics and hospitals in which their children were being seen for well-child checks, mild acute illness or chronic illness care (n = 3,718, 26.8%), and from a State Children's Health Insurance Program in California (n = 10 160, 73.2%). Results, The percentage of missing item responses for the parent-proxy report sample as a whole was 2.1%, supporting feasibility. The majority of the parent-proxy report scales across the age subgroups exceeded the minimum internal consistency reliability standard of 0.70 required for group comparisons, while the total scale scores across the age subgroups approached or exceeded the reliability criterion of 0.90 recommended for analysing individual patient scale scores. Construct validity was demonstrated utilizing the known groups approach. For each PedsQL scale and summary score, across age subgroups, healthy children demonstrated a statistically significant difference in HRQOL (better HRQOL) than children with a known chronic health condition, with most effect sizes in the medium-to-large effect size range. Conclusion, The results demonstrate the feasibility, reliability and validity of parent-proxy report at the individual age subgroup for ages 2,16 years. These analyses are consistent with recent FDA guidelines which require instrument development and validation testing for children and adolescents within fairly narrow age groupings and which determine the lower age limit at which reliable and valid responses across age categories are achievable. Even as paediatric patient self-report is advocated, there remains a fundamental role for parent-proxy report in paediatric clinical trials and health services research.
