Shared help seeking behaviour within families: a retrospective cohort study

Individual Life-Course Socioeconomic Position and Hearing Aid Use in the Atherosclerosis Risk in Communities Study

BACKGROUND

To measure the association between individual life-course socioeconomic position (SEP) and hearing aid use, we examined childhood and adulthood socioeconomic variables collected at the Atherosclerosis Risk in Communities (ARIC) study baseline visit (1987-1989)/Life Course Socioeconomic Status study (2001-2002) and hearing aid use data collected at visit 6 (2016-2017).

METHODS

ARIC is a prospective cohort study of older adults (45-64 years) recruited from 4 U.S. communities. This analysis included a subset of 2 470 participants with hearing loss at visit 6 (≥25 decibels hearing level [dB HL] better-ear) with complete hearing aid use data. Childhood SEP variables included parental education, parental occupation, and parental home ownership. Young and older adulthood SEP variables included income, education, occupation, and home ownership. Each life epoch was assigned a score ranging from 0 to 5 and then summed to calculate the individual cumulative SEP score. Multivariable-adjusted logistic regression was used to estimate the association between individual cumulative SEP and hearing aid use. Missing SEP scores were imputed for participants with incomplete socioeconomic data.

RESULTS

Of the 2 470 participants in the analytic cohort (median [interquartile interval] age 79.9 [76.7-84.0], 1 330 [53.8%] women, 450 [18.2%] Black), 685 (27.7%) participants reported hearing aid use. Higher cumulative SEP was positively associated with hearing aid use (odds ratio [OR] = 1.09, 95% confidence interval [CI]: 1.04-1.14), and slightly stronger for childhood (OR = 1.09, 95% CI: 1.00-1.20) than older adulthood SEP score (OR = 1.06, 95% CI: 0.95-1.18).

CONCLUSIONS

In this community-based cohort of older adults with hearing loss, higher individual life-course SEP was positively associated with hearing aid use.

Exploring Medical Expenditure Clustering and the Determinants of High-Cost Populations from the Family Perspective: A Population-Based Retrospective Study from Rural China

The costliest 5% of the population (identified as the “high-cost” population) accounts for 50% of healthcare spending. Understanding the high-cost population in rural China from the family perspective is essential for health insurers, governments, and families. Using the health insurance database, we tallied 202,482 families that generated medical expenditure in 2014. The Lorentz curve and the Gini coefficient were adopted to describe the medical expenditure clustering, and a logistic regression model was used to identify the determinants of high-cost families. Household medical expenditure showed an extremely uneven distribution, with a Gini coefficient of 0.76. High-cost families spent 54.0% of the total expenditure. The values for family size, average age, and distance from and arrival time to the county hospital of high-cost families were 4.05, 43.18 years, 29.67 km, and 45.09 min, respectively, which differed from the values of the remaining families (3.68, 42.46 years, 30.47 km, and 46.29 min, respectively). More high-cost families live in towns with low-capacity township hospitals and better traffic conditions than the remaining families (28.98% vs. 12.99%, and 71.19% vs. 69.6%, respectively). The logistic regression model indicated that family size, average age, children, time to county hospital, capacity of township hospital, traffic conditions, economic status, healthcare utilizations, and the utilization level were associated with high household medical expenditure. Primary care and health insurance policy should be improved to guide the behaviors of rural residents, reduce their economic burden, and minimize healthcare spending.

Sexual orientation differences in outpatient psychiatric treatment and antidepressant usage: evidence from a population-based study of siblings

In the past two decades, population-based health surveys have begun including measures of sexual orientation, permitting estimates of sexual orientation disparities in psychiatric morbidity and differences in treatment utilization. The present study takes advantage of the high-quality, comprehensive nationwide health registry data available in Sweden to examine whether psychiatric outpatient treatment for various diagnoses and antidepressant medication usage are greater in sexual minority individuals compared to their siblings. A longitudinal cohort study design was used with a representative random population-based sample in Stockholm, Sweden. Registry-based health record data on all specialized outpatient health care visits and prescription drug use was linked to a sample of 1154 sexual minority individuals from the Stockholm Public Health Cohort and their siblings. The main outcomes were treatment due to psychiatric diagnoses retrieved from nationwide registry-based health records. In analyses accounting for dependency between siblings, gay men/lesbians had a greater likelihood of being treated for mood disorder [adjusted odds ratio (AOR) 1.77; 99% confidence intervals (CI) 1.00, 3.16] and being prescribed antidepressants (AOR 1.51; 99% CI 1.10, 2.07) compared to their siblings. Further, bisexual individuals had a greater likelihood of any outpatient psychiatric treatment (AOR 1.69; 99% CI 1.17, 2.45) and being prescribed antidepressants (AOR 1.48; 99% CI 1.07, 2.05) as well as a greater likelihood of being treated for a mood disorder (AOR 1.98; 99% CI 1.33, 2.95) compared to their siblings. No difference in anxiety or substance use disorder treatment was found between any sexual minority subgroup and their siblings. The potential role of familial confounding in psychiatric disorder treatment was not supported for more than half of the outcomes that were examined. Results suggest that sexual minority individuals are significantly more likely to be treated for certain psychiatric disorders compared to their siblings. Future research is needed to understand mechanisms other than familial factors that might cause the substantial treatment differences based on sexual orientation reported here.

Mistrust in Physicians does not Explain Black-white Disparities in Primary Care and Emergency Department Utilization: The Importance of Socialization During the Jim Crow era

PURPOSE

Compared to whites, blacks under-utilize primary care (PC) and over-utilize emergency department (ED) services. The aim of this study is to determine whether mistrust in physicians explains these black-white disparities, and the potentially modifying influence of socialization under racially segregated health care (i.e., raised in the U.S. South during the Jim Crow era).

METHODS

Data come from the nationally representative Americans' Changing Lives Study (n=1,578). Poisson regression techniques are utilized to respectively model PC and ED utilization among a sample of non-Hispanic black and white adults aged forty-years and older.

CONCLUSION

Mistrust in physicians does not explain black-white disparities in PC or ED utilization. Blacks under-utilize PC services compared to whites, net of predisposing, need, and enabling factors, but this is especially apparent among blacks who were raised in the U.S. south during the Jim Crow era and continue to reside in the South. Blacks greatly over-utilize ED services compared to whites, but this is greatest among those raised in the south during the Jim Crow era and/or those currently residing in the South.

Chronic pain in families: a cross-sectional study of shared social, behavioural, and environmental influences

Chronic pain is common and creates a significant burden to the individual and society. Emerging research has shown the influence of the family environment on pain outcomes. However, it is not clear what shared factors between family members associate with chronic pain. This study aimed to investigate the family-level contribution to an individual's chronic pain status. This was a cross-sectional study using the Generation Scotland: Scottish Family Health Study data set. This study focused on a nested cohort of dyads (only 2 relatives per family, n = 2714). Multi-level modelling was first performed to estimate the extent of variance in chronic pain at the family level. Then each member of the dyad was randomly assigned as either the exposure or outcome family member, and logistic regression was used to identify shared factors associated with the outcome of chronic pain status. Multi-level modelling showed just under 10% of variation in chronic pain status was at a family level. There was an increase in odds of chronic pain if exposure family member had chronic pain (odds ratio [OR]: 1.30, 95% confidence interval [CI]: 1.02-1.65), if both were women (OR: 1.39, 95% CI: 0.99-1.94), if both were older in age (OR: 1.80, 95% CI: 1.31-2.48), and if both had low household income (OR: 3.27, 95% CI: 1.72-6.21). These findings show that most explanation for chronic pain is still at the individual level. However, some significant shared effects between family members associate with chronic pain, and this highlights the influence of the family context.

Examining the structure and behavior of Afghanistan’s routine childhood immunization system using system dynamics modeling

Purpose

The purpose of this paper is to demonstrate how public health and systems science methods can be combined to examine the structure and behavior of Afghanistan’s routine childhood immunization system to identify the pathways through which health system readiness to deliver vaccination services may extend beyond immunization outcomes.

Design/methodology/approach

Using findings from an ecological study of Afghanistan’s immunization system and a literature review on immunization program delivery, the routine immunization system was mapped using causal loop diagrams. Next, a stock-and-flow diagram was developed and translated to a system dynamics (SD) model for a system-confirmatory exercise. Data are from annual health facility assessments and two cross-sectional household surveys. SD model results were compared with measured readiness and service outcomes to confirm system structure.

Findings

Readiness and demand-side components were associated with improved immunization coverage. The routine immunization system was mapped using four interlinking readiness subsystems. In the SD model, health worker capacity and demand-side factors significantly affected maternal health service coverage. System readiness components affected their future measures mostly negatively, which may indicate that the reinforcing feedback drives current system-structured behavior.

Originality/value

The models developed herein are useful to explore the potential impact of candidate interventions on service outcomes. This paper documents the process through which public health and systems investigators can collaboratively develop models that represent the feedback-driven behavior of health systems. Such models allow for more realistically addressing health policy and systems-level research questions.

Healthcare seeking behaviour of students living on their own compared to those living in the parental home: a cross-sectional study

Objective This study aimed to investigate differences in healthcare seeking behaviour and barriers between students living in the parental home and those living on their own. Participants Five hundred and six second year students of the University of Amsterdam (UvA), interviewed in March and April 2015. Methods In a paper-and-pencil survey, questions were asked about the students' healthcare seeking behaviour and barriers. Differences according to residency were analysed with χ2-tests and regression models. Results The frequency of healthcare seeking behaviour varied according to residency, but none of the differences were statistically significant. Yet, a proportion of students living on their own visited primary healthcare providers less often after they changed residency (23.7% for general practitioner and 41.8% for dentist). Travel distance and lack of time were most often mentioned as barriers to students living on their own. Conclusion The barriers implicate the importance of encouraging students living on their own to switch to a new general practitioner or dentist.

Characteristics and respiratory risk profile of children aged less than 5 years presenting to an urban, Aboriginal-friendly, comprehensive primary health practice in Australia

AIM

There are no published data on factors impacting on acute respiratory illness (ARI) among urban Indigenous children. We describe the characteristics and respiratory risk profile of young urban Indigenous children attending an Aboriginal-friendly primary health-care practice.

METHODS

We conducted a cross-sectional analysis of data collected at baseline in a cohort study investigating ARI in urban Indigenous children aged less than 5 years registered with an Aboriginal primary health-care service. Descriptive analyses of epidemiological, clinical, environmental and cultural factors were performed. Logistic regression was undertaken to examine associations between child characteristics and the presence of ARI at baseline.

RESULTS

Between February 2013 and October 2015, 180 Indigenous children were enrolled; the median age was 18.4 months (7.7-35), 51% were male. A total of 40 (22%) children presented for a cough-related illness; however, ARI was identified in 33% of all children at the time of enrolment. A total of 72% of children were exposed to environmental tobacco smoke. ARI at baseline was associated with low birthweight (adjusted odds ratio (aOR) 2.54, 95% confidence interval (CI) 1.08-5.94), a history of eczema (aOR 2.67, 95% CI 1.00-7.15) and either having a family member from the Stolen Generation (aOR 3.47, 95% CI 1.33-9.03) or not knowing this family history (aOR 3.35, 95% CI 1.21-9.26).

CONCLUSIONS

We identified an urban community of children of high socio-economic disadvantage and who have excessive exposure to environmental tobacco smoke. Connection to the Stolen Generation or not knowing the family history may be directly impacting on child health in this community. Further research is needed to understand the relationship between cultural factors and ARI.

The impact of continuity of care on emergency room use in a health care system without referral management: an instrumental variable approach

PURPOSE

The purpose of the study was to determine whether continuity of care (COC) is beneficial in national health care systems without referral management by controlling for endogeneity of COC.

METHODS

We used National Health Insurance (Taiwan) claims data from 2008, encompassing approximately 23 million people, to determine whether COC is associated with reduced emergency room (ER) use by hypertension and diabetic patients in 2009. We used an instrumental variable approach to account for endogeneity associated with patients' COC levels.

RESULTS

After controlling for endogeneity, the marginal effect of COC on ER use probability when the COC score increased from 0 to 1 was 7.6% (P < .001) and 14.8% (P < .001) for hypertension and diabetic patients, respectively.

CONCLUSIONS

We determined that COC is more effective for reducing ER use than are models that assume that COC is exogenous. It has been argued that in many countries, health care systems without referral management encourage physician shopping and hinder physician-patient communication. However, there are benefits to disease-specific COC. Because current estimations have failed to take endogeneity biases into account, COC is more effective than is currently assumed.

In sickness and in health: A cross-sectional analysis of concordance for musculoskeletal pain in 13,507 couples

Background

Musculoskeletal pain conditions are common and create substantial burden for the individual and society. While research has shown concordance between couples for risk of some diseases, e.g. heart disease or diabetes, little information is available on such effects for musculoskeletal pain conditions. Our aims were to investigate the presence of concordance between couples for consultations about pain, and to examine theoretical influences on such concordance.

Methods

This was a 1‐year cross‐sectional study of musculoskeletal pain consultations in a UK primary care database. In total 27,014 patients (13,507 couples) aged between 30 and 74 years were included. The main outcome measure was the presence of a musculoskeletal morbidity read code indicating a consultation for musculoskeletal conditions (any, back, neck, knee, shoulder, foot, osteoarthritis). Logistic regression was used to test associations with odds ratios (OR) and 95% confidence intervals (95% CI).

Results

Patients whose partner had a musculoskeletal pain consultation were also more likely to consult for a musculoskeletal condition (OR 1.22, 95% CI 1.12–1.32). This association was found to be strongest for shoulder disorders (OR 1.91, 95% CI 1.06–3.47). No significant associations were found for other pain conditions.

Conclusion

Results show that partner concordance is present for consultations for some musculoskeletal conditions but not others. Possible explanations for concordance include the shared health behaviours between couples leading to potential heightened awareness of symptoms. Given the high prevalence of musculoskeletal pain within populations, it may be worth considering further the mechanisms that explain partner concordance.

A cross-national comparative study on the influence of individual life course factors on mammography screening

OBJECTIVES

Drawing on insights from the life course perspective, the aim of this paper is to gain a better understanding of persistent socioeconomic inequalities related to the uptake of mammography screening in 13 European countries. We examine whether these inequalities originate in childhood and relate them to the history and progression of each country's screening programs.

METHODS

Retrospective data from the third wave of the Survey of Health, Ageing and Retirement (SHARELIFE) is analyzed by means of event-history analyses to examine the role of childhood preventive health behavior on mammography screening initiation. The results are framed within the context of policy developments concerning mammography screening in each of the separate European countries.

RESULTS

Childhood preventive health care behavior predicts mammography screening in 9 of the 13 countries after conventional measurements of socioeconomic position in childhood and adulthood are accounted for. Net effects of education and income are still found for respectively 6 and 7 countries, but in about half of these countries national screening programs are able to reduce the social gradient. Very strong cohort and period effects are found for every country.

CONCLUSIONS

In a substantial number of the European countries, socioeconomic inequalities in preventive health behavior originate in childhood, which point to the deeply rooted nature of these inequalities. A long-term perspective is essential to further unravel how health policies can reduce or eliminate these persistent inequalities.

Increased use of recommended maternal health care as a determinant of immunization and appropriate care for fever and diarrhoea in Ghana: an analysis pooling three demographic and health surveys

OBJECTIVE

Enhancing maternal and child health are key Millennium Development Goals (MDGs). This study examined whether increased utilization of recommended maternal health care (MHC), is associated with factors that improve children's health; specifically, complete immunization and appropriate care for fever and diarrhoea in Ghana.

DESIGN

Data from the 1998, 2003, and 2008 Ghana Demographic and Health Surveys were pooled for a nationally representative sample of 6786 women aged 15-49 years who had a child in the previous 5 years. Children aged 12-23 months were considered fully immunized if they received all eight basic immunizations. Appropriate care for children under-five was receipt of medical treatment for fever or oral rehydration therapy for diarrhoea. The effect of recommended MHC utilization (characterized as poor, intermediate or best use) on immunization and appropriate care for fever and diarrhoea was determined through logistic regression with Andersen's Behavioural Model guiding co-variate selection.

RESULTS

Increased MHC utilization (reference: intermediate MHC use) increased the odds of immunization [poor use: odds ratio (OR) = 0.54, 95% confidence interval (CI): 0.42-0.69; best use: OR = 1.29, 95% CI: 1.01-1.67], as well as appropriate care for fever (poor use: OR = 0.55, 95% CI: 0.35-0.88; best use: OR = 1.72, 95% CI: 1.17-2.52) and diarrhoea (poor use: OR = 0.63, 95% CI: 0.43-0.93). Survey year and region also predicted each outcome. Other determinants of immunization were maternal education, ethnicity, religion, media exposure, wealth and birth weight. Determinants of appropriate care for fever included paternal education, media exposure and wealth, and for diarrhoea, child's age and birth weight.

CONCLUSION

This study proposes a linkage between MDGs; initiatives to improve maternal health through promoting increased use of recommended MHC may enhance children's health-related care. This could be useful for countries with limited resources in achieving MDGs, especially in sub-Saharan Africa where under-five mortality is the highest.

Asthma in children born after infertility treatment: findings from the UK Millennium Cohort Study

STUDY QUESTION

Is asthma more common in children born after subfertility and assisted reproduction technologies (ART)?

SUMMARY ANSWER

Yes. Asthma, wheezing in the last year and anti-asthmatic medication were all more common in children born after a prolonged time to conception (TTC). This was driven specifically by an increase in children born after ART.

WHAT IS KNOWN ALREADY

Few studies have investigated any association between ART and asthma in subsequent children, and findings to date have been mixed. A large registry-based study found an increase in asthma medication in ART children but suggests underlying infertility is the putative risk factor. Little is known about asthma in children after unplanned or mistimed conceptions.

STUDY DESIGN, SIZE, DURATION

The Millennium Cohort Study is a UK-wide, prospective study of 18 818 children recruited at 9 months of age. Follow-up is ongoing. This study analyses data from follow-up surveys at 5 and 7 years of age (response rates of 79 and 70%, respectively).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Singleton children whose natural mothers provided follow-up data were included. Mothers reported whether their pregnancy was planned; planners provided TTC and details of any ART. The population was divided into 'unplanned' (unplanned and unhappy), 'mistimed' (unplanned but happy), 'planned' (planned, TTC < 12 months), 'untreated subfertile' (planned, TTC >12 months), 'ovulation induced' (received clomiphene citrate) and 'ART' (IVF or ICSI). The primary analysis used the planned children as the comparison group; secondary analysis compared the treatment groups to the children born to untreated subfertile parents. Outcomes were parent report of asthma and wheezing at 5 and 7 years, derived from validated questions in the International Study of Asthma and Allergies in Childhood, plus use of anti-asthmatic medications. A total of 13 041 (72%) children with full data on asthma and confounders were included at 5 years of age, and 11 585 (64%) at 7 years.

MAIN RESULTS AND THE ROLE OF CHANCE

Compared with planned children, those born to subfertile parents were significantly more likely to experience asthma, wheezing and to be taking anti-asthmatics at 5 years of age [adjusted odds ratio (OR): 1.39 (95% confidence interval (CI): 1.07, 1.80), OR: 1.27 (1.00, 1.63) and OR: 1.90 (1.32,2.74), respectively]. This association was mainly related to an increase among children born after ART (adjusted OR: 2.65 (1.48, 4.76), OR: 1.97, (1.10, 3.53) and OR: 4.67 (2.20, 9.94) for asthma, wheezing and taking anti-asthmatics, respectively). The association was also present, though reduced, at the age of 7 years.

LIMITATIONS, REASONS FOR CAUTION

The number of singletons born after ART was relatively small (n = 104), and as such the findings should be interpreted with caution. However, data on a wide range of possible confounding and mediating factors were available and analysed. The data were weighted for non-response to minimize selection bias.

WIDER IMPLICATIONS OF THE FINDINGS

The findings add to the growing body of evidence suggesting an association between subfertility, ART and asthma in children. Further work is needed to establish causality and elucidate the underlying mechanism. These findings are generalizable to singletons only, and further work on multiples is needed.

Families’ visits to practitioners of complementary and alternative medicine in a total population (the HUNT studies)

Aims: To investigate characteristics of families with adolescent children who have visited practitioners of complementary and alternative medicine (CAM). Methods: The Nord-Trøndelag Health Studies (HUNT) invited all inhabitants aged 13 years and older to a population-based study. The data of parents and adolescents were merged through the Norwegian family register. A family CAM visitor was a family where either the adolescent or the mother or father had visited a CAM practitioner in the previous year. The data were analyzed using multivariable logistic regression. Results: A total of 7,888 adolescents with mother and/or fathers were included. The prevalence of families visiting CAM practitioners was 19.8%. The odds of a family visiting a CAM practitioner was significantly associated (p < 0.01) with a father with poor self-reported global health (adjusted odds ratio (adjOR) 3.0, 95% confidence interval (95% CI) 1.7—5.3), who exercised (adjOR 1.3, 1.1—1.5) or smoked daily (adjOR 0.7, 0.6—0.8). Family CAM visits were also associated with the mother having a recent health complaint (adjOR 1.4, 1.1—1.7) or having fair global health (adjOR 1.6, 1.2—2.0), or with the adolescent, mother or father having visited a general practitioner during the past year (adolescent adjOR 1.3, 1.2—1.5; mother 1.7, 1.5—2.0; father 1.4, 1.2—1.6). For family visits to a homeopath, the strongest association was the mother having visited a general practitioner (adjOR 1.9, 1.4—2.5). For visits to chiropractors the strongest association was whether the father was currently working (adjOR 2.1, 1.2—3.8). Conclusions: The factor most strongly associated with families’ visits to CAM practitioners was a father who had poor self-reported health.

Individuals receiving addiction treatment: are medical costs of their family members reduced?

AIMS

To examine whether alcohol and other drug (AOD) treatment is related to reduced medical costs of family members.

DESIGN

Using the administrative databases of a private, integrated health plan, we matched AOD treatment patients with health plan members without AOD disorders on age, gender and utilization, identifying family members of each group.

SETTING

Kaiser Permanente Northern California.

PARTICIPANTS

Family members of abstinent and non-abstinent AOD treatment patients and control family members.

MEASUREMENTS

We measured abstinence at 1 year post-intake and examined health care costs per member-month of family members of AOD patients and of controls through 5 years. We used generalized estimating equation methods to examine differences in average medical cost per member-month for each year, between family members of abstinent and non-abstinent AOD patients and controls. We used multilevel models to examine 4-year cost trajectories, controlling for pre-intake cost, age, gender and family size.

RESULTS

AOD patients' family members had significantly higher costs and more psychiatric and medical conditions than controls in the pre-treatment year. At 2-5 years, each year family members of AOD patients abstinent at 1 year had similar average per member-month medical costs to controls (e.g. difference at year 5 = $2.63; P > 0.82), whereas costs for family members of non-abstinent patients were higher (e.g. difference at year 5 = $35.59; P = 0.06). Family members of AOD patients not abstinent at 1 year, had a trajectory of increasing medical cost (slope = $10.32; P = 0.03) relative to controls.

CONCLUSIONS

Successful AOD treatment is related to medical cost reductions for family members, which may be considered a proxy for their improved health.

Registration for public drug benefits across areas of differing ethnic composition in British Columbia, Canada

Background

In 2003, the government of British Columbia, Canada introduced a universal drug benefit plan to cover drug costs that are high relative to household income. Residents were required to register in order to be eligible for the income-based benefits. Given past research suggesting that registration processes may pose an access barrier to certain subpopulations, we aimed to determine whether registration rates varied across small geographic areas that differed in ethnic composition.

Methods

Using linked population-based administrative databases and census data, we conducted multivariate logistic regression analyses to determine whether the probability of registration for the public drug plan varied across areas of differing ethnic composition, controlling for household-level predisposing, enabling and needs factors.

Results

The adjusted odds of registration did not differ across regions characterized by high concentrations (greater than 30%) of residents identifying as North American, British, French or other European. Households located in areas with concentrations of residents identifying as an Asian ethnicity had the highest odds of program registration: Chinese (OR = 1.21, CI: 1.19-1.23) and South Asian (OR = 1.19, CI: 1.16-1.22). Despite this positive finding, households residing in areas with relatively high concentrations of recent immigrants had slightly lower adjusted odds of registering for the program (OR = 0.97, CI: 0.95-0.98).

Conclusions

This study identified ethnic variation in registration for a new public drug benefit program in British Columbia. However, unlike previous studies, the variation observed did not indicate that areas with high concentrations of certain ethnicities experienced disadvantages. Potential explanations are discussed.

'Containment' as an analytical framework for understanding patient delay: a qualitative study of cancer patients' symptom interpretation processes

Recent decades have seen much variation in survival and mortality among European cancer patients, with rather small increases in survival, especially among patients in UK and Denmark. This poor outcome has been ascribed tentatively to patient delay since an estimated 20-25% of all cancer patients report having experienced cancer-related symptoms for more than three months before seeking care. In this article we analyse semi-structured interviews with 30 adult Danish cancer patients and their families. Special focus is given to symptom interpretation processes, and how these processes potentially delay care-seeking decisions. The paper adopts a contextual approach inspired mainly by the sociologist Alonzo's (1979, 1984) concept of containment. Alonzo's theory is supplemented with recent anthropological and sociological literature on how people establish the relation between bodily sensations and symptoms and decide how to respond adequately to these. We present an analysis illustrating that bodily sensations and symptoms are potentially contained in a dynamic interplay of factors related to specific social situations, life biographies and life expectations and their accordance with culturally acceptable values and explanations. Finally, we discuss the implications of the analysis for future studies on patient delay.

Health effects of life transitions for women and children: a research model for public and community health nursing

Because maternal-child populations have traditionally been a major practice target for public and community health nursing (P/CHN), understanding the health effects of life transition experiences for women and their children is key to the advancement of P/CHN practice and research. To date there are no integrated conceptual models available that examine transition and its health effects in women, and ultimately their children, to single or multiple transitions. In order to help women and those with dependent children transition successfully, strong transition frameworks for nursing are needed. The purpose of this paper is to describe a conceptual model, Health Effects of Life Transition for Women and Children. Major components include the transition experience (developmental, situational, health illness), transition assets/risks (personal, environmental), cognitive-behavioral health indicators of transition (perception of situation, personal efficacy, change readiness, engagement, help-seeking, health behaviors, services use), transition adaptive outcomes of health (health status, intensity of need for nursing care) and competence (transition specific skill acquisition, health management, resourcefulness) and long-term preventive health outcomes (risk reduction, disability prevention, cost savings, mastery, injury prevention). The authors propose that cognitive-behavioral health indicators are foundational to a successful transition experience, are why some people have better transition outcomes than others, and when influenced by P/CHN intervention lead to improved long-term outcomes.

Is new drug prescribing in primary care specialist induced?

BACKGROUND

Medical specialists are often seen as the first prescribers of new drugs. However, the extent to which specialists influence new drug prescribing in primary care is largely unknown.

METHODS

This study estimates the influence of medical specialists on new drug prescribing in primary care shortly after market introduction. The influence of medical specialists on prescribing of five new drugs was measured in a cohort of 103 GPs, working in 59 practices, over the period 1999 until 2003. The influence of medical specialists on new drug prescribing in primary care was assessed using three outcome measures. Firstly, the proportion of patients receiving their first prescription for a new or reference drug from a specialist. Secondly, the proportion of GPs prescribing new drugs before any specialist prescribes to their patients. Thirdly, we compared the time until the GP's first own prescribing between GPs who waited for prescriptions from specialists and those who did not.

RESULTS

The influence of specialists showed considerable differences among the new drugs studied. The proportion of patients receiving their first prescription from a specialist was greatest for the combination salmeterol/fluticasone (60.2%), and lowest for rofecoxib (23.0%). The proportion of GPs prescribing new drugs before waiting for prescriptions from medical specialists ranged from 21.1% in the case of esomeprazole to 32.9% for rofecoxib. Prescribing new drugs by specialists did not shorten the GP's own time to prescribing.

CONCLUSION

This study shows that the influence of medical specialists is clearly visible for all new drugs and often greater than for the existing older drugs, but the rapid uptake of new drugs in primary care does not seem specialist induced in all cases. GPs are responsible for a substantial amount of all early prescriptions for new drugs and for a subpopulation specialist endorsement is not a requisite to initiate in new drug prescribing. This contradicts with the idea that the diffusion of newly marketed drugs always follows a two-step model, with medical specialists as the innovators and GPs as the followers.

What drives prescribing of asthma medication to children? A multilevel population-based study

PURPOSE

Diagnosing asthma in children with asthmatic symptoms remains a challenge, particularly in preschool children. This challenge creates an opportunity for variability in prescribing. The aim of our study was to investigate how and to what degree patient, family, and physician characteristics influence prescribing of asthma medication in children.

METHODS

We undertook a multilevel population-based study using the second Dutch national survey of general practice (DNSGP-2), 2001. Participants were 46,371 children aged 1 to 17 years belonging to 25,537 families registered with 109 general practitioners. Using a multilevel multivariate logistic regression analysis with 3 levels, our main outcome measure was the prescribing of asthma medication, defined as at least 1 prescription for beta(2)-adrenergic agonists, inhaled corticosteroids, cromones, or montelukast during the 1-year study period.

RESULTS

We identified characteristics significantly associated with prescribing asthma medication on all 3 levels (child, family, and physician). The variance in prescribing among physicians was significantly higher with children who were younger than 6 years than with children aged 6 years and older (95% CI, 3.5%-25.2% vs 2.4%-13.4%). Several diagnoses other than asthma and asthmatic complaints were strongly associated with prescribing asthma medication, including bronchitis/bronchiolitis (OR = 9.04; 95% CI, 7.57-10.8) and cough (OR = 6.51; 95% CI, 5.68-7.47).

CONCLUSIONS

Our study shows a much higher variance in prescribing patterns among general practitioners for children younger than 6 years compared with older children, which could be a direct result of the diagnostic complexities found in young children with asthmatic symptoms. Thus diagnostic gaps may lead to more physician-driven prescribing irrespective of the clinical context.

Is social support from family associated with PSA testing? An exploratory analysis using the Health Information National Trends Survey (HINTS) 2005

African American and White men have the highest rates of prostate cancer in the United States. Families represent important social contexts within which illness occurs.The purpose of this study is to explore whether prostate-specific antigen (PSA) testing is associated with instrumental and informational social support from family members among a sample of Black and White men aged 45 and older. Data from the 2005 Health Information National Trends Survey were analyzed using logistic regression. The dependent variable was having a PSA test within the past year or less. The independent variables consisted of selected demographic and family informational and instrumental social support variables. The statistically significant variables included age and having a family member with cancer. Additional studies to elucidate the mechanisms of social support from family for prostate cancer are needed.

Taking account of context: how important are household characteristics in explaining adult health-seeking behaviour? The case of Vietnam

Understanding the factors affecting the utilization of health services is essential for health planners, especially in low income countries where increasing access to and use of health services is one of the main policy goals of government. While much has been written on adult health-seeking behaviour, there is comparatively little known about the influence of the broader context such as the effects of family and community on individual use of health care services in low income countries. Using Vietnam's latest National Household Survey data, this paper empirically assesses the influence of individual- and household-level factors on the use of health care services, while controlling for the unobserved household-level effects. The estimates obtained from a multilevel logistic regression model suggest that the individual's likelihood of seeking treatment is jointly determined by the observed individual- and household-level characteristics as well as unobserved household-level effects. The chance of seeking medical treatment when ill varies strongly with the observed individual- and household-level covariates, including health insurance status, income, the type and severity of illness, the number of other household members with an ailment and the presence of young children in the household. However, the variability implied by the unobservable household-level effects outweighs the variability implied by the observed covariates, indicating a high degree of homogeneity in health-seeking behaviour among the household members. Failure to take account of homogeneity in health-seeking behaviour among the household members leads not only to biased results but also to inefficient policy targeting. Policies aimed at increasing access to and the use of medical services need to be sympathetic to both individuals and households.

Parental use of the Internet to seek health information and primary care utilisation for their child: a cross-sectional study

BACKGROUND

Using the Internet to seek health information is becoming more common. Its consequences on health care utilisation are hardly known in the general population, in particular among children whose parents seek health information on the Internet. Our objective was to investigate the relationship between parental use of the Internet to seek health information and primary care utilisation for their child.

METHODS

This cross-sectional survey has been carried out in a population of parents of pre-school children in France. The main outcome measure was the self-reported number of primary care consultations for the child, according to parental use of the Internet to seek health information, adjusted for the characteristics of the parents and their child respectively, and parental use of other health information sources.

RESULTS

A total of 1,068 out of 2,197 questionnaires were returned (response rate of 49%). No association was found between parental use of the Internet to seek health information and the number of consultations within the last 12 months for their child. Variables related to the number of primary care consultations were characteristics of the child (age, medical conditions, homeopathic treatment), parental characteristics (occupation, income, stress level) and consultation of other health information sources (advice from pharmacist, relatives).

CONCLUSION

We did not find any relationship between parental use of the Internet to seek health information and primary care utilisation for children. The Internet seems to be used as a supplement to health services rather than as a replacement.

Characteristics of children consulting for cough, sore throat, or earache

BACKGROUND

GPs are often consulted for respiratory tract symptoms in children.

AIM

To explore characteristics of children, their parents, and their GPs that are correlated with consulting a GP for cough, sore throat, or earache.

DESIGN OF STUDY

Second Dutch National Survey of General Practice (DNSGP-2) with a health interview and an additional questionnaire.

SETTING

Children aged 0-17 years registered with 122 GPs in Dutch general practice.

METHOD

Characteristics of patients and their GPs were derived from the DNSGP-2 health interview and a questionnaire, respectively. Characteristics of the illness symptoms and GP consultation were acquired by means of an additional questionnaire. Data were analysed using multivariate logistic regression.

RESULTS

Of all children who completed the questionnaire, 550 reported cough, sore throat, or earache in the 2 weeks preceding the interview with 147 of them consulting their GP. Young children more frequently consulted the GP for respiratory symptoms, as did children with fever, longer duration of symptoms, those reporting their health to be 'poor to good', and living in an urban area. When parents were worried, and when a child or their parents were cued by someone else, the GP was also consulted more often. GP-related determinants were not associated with GP consultation by children.

CONCLUSION

This study emphasises the importance of establishing the reasons behind children with respiratory tract symptoms consulting their GP. When GPs are aware of possible determinants of the decision to consult a GP, more appropriate advice and reassurance can be given regarding these respiratory symptoms, which are generally self-limiting.

Determinants of health care utilization for respiratory symptoms in the first year of life

OBJECTIVE

Health care utilization for respiratory symptoms is very common in infancy. Little is known about the determinants of visiting a physician for such complaints in infants. We investigated which factors determine the likelihood of visiting a physician for respiratory symptoms in the first year of life of their offspring.

PATIENTS AND METHODS

Infants were participants of the ongoing Wheezing Illnesses Study Leidsche Rijn (WHISTLER), a prospective birth cohort study on respiratory illnesses. Parental reports on respiratory symptoms and possible risk factors were assessed by daily questionnaires. Physician diagnosed respiratory symptoms were classified in medical records using the International Classification of Primary Care. Outcome was defined as a having a child visit a general practitioner for respiratory symptoms in the first year of life. Logistic regression was used to study the likelihood of outcome (yes/no) as a function of putative predictors.

RESULTS

Forty-seven percent of the infants visited a physician for respiratory symptoms in the first year of life. Every extra week of respiratory symptoms was associated with a 4.3% higher chance (odds ratio [OR], 1.043; 95% confidence interval [CI], 1.022-1.065) of visiting a physician. Furthermore, the chance was higher in boys (OR, 1.5; 95% CI, 1.1-2.1), children attending day care (OR, 1.9; 95% CI, 1.2-3.0), children with nonwhite mothers (OR, 1.9; 95% CI, 1.1-3.2), and children whose mother had supplementary health care insurance (OR, 1.7; 95% CI, 1.1-2.7). Findings were similar within the subgroup of children with serious respiratory symptoms (>median: 46 d/yr), but in that group parental age over 30 also determined physician visits (OR, 3.8; 95% CI, 1.6-8.9).

CONCLUSIONS

Child and parent characteristics, besides complaints per se, play an important role in health care utilization for respiratory illnesses in infancy.

Prospective cohort study into post-disaster benzodiazepine use demonstrated only short-term increase

OBJECTIVES

Benzodiazepines are typically prescribed for anxiety and insomnia, two complaints often reported after disasters. Benzodiazepines can cause mental or physical dependence, especially when taken for a long time. This study aims at evaluating benzodiazepine use in a disaster-stricken community with the help of computer-based records.

STUDY DESIGN AND SETTING

This prospective cohort study covers a period of 4 years. For every patient, predisaster baseline data are available. Multilevel regression is applied to study differences in benzodiazepine use in 496 patients whose children were involved in the Volendam café fire on January 1, 2001 compared with 1,709 community controls, and 4,530 patients from an unaffected cohort.

RESULTS

In community controls and patients from the unaffected cohort, benzodiazepine use remained stable in the course of the years. In the first year postfire, parents of disaster victims were 1.58 times more likely to use benzodiazepines than community controls (95% confidence interval 1.13-2.23). With regard to long-term use, differences between community controls and parents were statistically nonsignificant.

CONCLUSIONS

In the studied community, benzodiazepines were predominantly prescribed as a short-term intervention. Clinical guidelines that advocate a conservative prescription policy were well adhered to.

The excess medical cost and health problems of family members of persons diagnosed with alcohol or drug problems

BACKGROUND

Having a family member with substance use problems affects family functioning, which may lead to increased medical problems and increased health care utilization and costs in the other family members.

AIM

We sought to estimate the excess medical costs and prevalence of diagnosed health conditions of family members of persons with an alcohol or drug diagnosis (AOD) compared with the family members of similar persons without an AOD.

METHODS

Using a large health plan's administrative databases, we identified persons who received an AOD between 2001 and 2004 and a similar group of persons with no AOD during that time. Using a hierarchical linear mixed model, we compared the cost and utilization of the family members of the AOD and non-AOD patients in the 2 years prior to the AOD patient's first AOD. Using logistic regression, we determined whether the family members of patients with AODs were more likely than comparison family members to be diagnosed with medical conditions.

RESULTS

Family members of patients with AODs had greater health care costs than comparison family members in the second year before the index date (490 dollars) and in the year before the index date (433 dollars). This was the case for both adult and child family members. They also were more likely to be diagnosed with many medical conditions, especially substance abuse and depression.

CONCLUSIONS

Family members of patients with AODs have greater health care costs and are more likely to be diagnosed with a number of medical conditions than family members of similar persons without an AOD.

Striking variations in consultation rates with general practice reveal family influence

Background

The reasons why patients decide to consult a general practitioner vary enormously. While there may be individual reasons for this variation, the family context has a significant and unique influence upon the frequency of individuals' visits. The objective of this study was to explore which family factors can explain the differences between strikingly high, and correspondingly low, family consultation rates in families with children aged up to 21.

Methods

Data were used from the second Dutch national survey of general practice. This survey extracted from the medical records of 96 practices in the Netherlands, information on all consultations with patients during 2001. We defined, through multilevel analysis, two groups of families. These had respectively, predominantly high, and low, contact frequencies due to a significant family influence upon the frequency of the individual's first contacts. Binomial logistic regression analyses were used to analyse which of the family factors, related to shared circumstances and socialisation conditions, can explain the differences in consultation rates between the two groups of families.

Results

In almost 3% of all families, individual consultation rates decrease significantly due to family influence. In 11% of the families, individual consultation rates significantly increase due to family influence. While taking into account the health status of family members, family factors can explain family consultation rates. These factors include circumstances such as their economic status and number of children, as well as socialisation conditions such as specific health knowledge and family beliefs. The chance of significant low frequencies of contact due to family influences increases significantly with factors such as, paid employment of parents in the health care sector, low expectations of general practitioners' care for minor ailments and a western cultural background.

Conclusion

Family circumstances can easily be identified and will add to the understanding of the health complaints of the individual patient in the consulting room. Family circumstances related to health risks often cannot be changed but they can illuminate the reasons for a visit, and mould strategies for prevention, treatment or recovery. Health beliefs, on the other hand, may be influenced by providing specific knowledge.

All in the family: headaches and abdominal pain as indicators for consultation patterns in families

PURPOSE

Headaches and abdominal pain are examples of minor ailments that are generally self-limiting. We examined the extent to which patterns of visits to family physicians for minor ailments, such as headaches or abdominal pain, cluster within families.

METHODS

Using information from the Second Dutch National Survey of General Practice for 96 family practices, we analyzed the visits of families with at least 1 child aged 12 years or younger during a period of 12 months.

RESULTS

Family patterns were clearest in the visits of mothers and children. A large part of the similarity in the frequencies of contact by mothers and daughters could be attributed to shared family factors. This finding was especially true for families with a child who had a headache or abdominal pain as the presenting symptom, rather than physical trauma or chronic disease. Within families, we did not find any specific patterns of diagnoses. Diagnoses were recorded by family physicians. In the case of young children, family similarity may have been overestimated because parents initiated the visits and put their child's health problem into words.

CONCLUSIONS

Visits to family physicians for headaches or abdominal pain can be seen as indicators of consultation patterns in families. Family patterns related to minor ailments are likely to be a result of socialization. Family consultation patterns might point toward specific needs of families and consequently at a different approach to treatment.

Why does it run in families? Explaining family similarity in help-seeking behaviour by shared circumstances, socialisation and selection

Why do contact frequencies with general practice of family members resemble each other? Many aspects related to the clustering of health-care utilisation within families have been studied, but the underlying mechanisms have not been addressed. This article considers whether family similarity in contact frequency with general practice can be explained as (a) a result of shared circumstances, (b) through socialisation, and (c) through homogeneity of background characteristics. Data from the second Dutch national survey of general practice were used to test these mechanisms empirically. This survey recorded all consultations in 2001 for 104 general practices in the Netherlands, serving 385,461 patients. Information about socio-demographic characteristics was collected by means of a patient survey. In a random sample, an extended health interview took place (n=12,699). Overall, we were able to show that having determinants in common through socialisation and shared circumstances can explain similarity in contact frequencies within families, but not all hypotheses could be confirmed. In specific terms, this study shows that resemblances in contact frequencies within families can be best explained by spending more time together (socialisation) and parents and children consulting a general practitioner simultaneously (circumstances of the moment). For general practitioners, the mechanisms identified can serve as a framework for a family case history. The importance of the mechanism of socialisation in explaining similarities in help-seeking behaviour between family members points to the significance of knowledge and health beliefs underlying consultation behaviour. An integrated framework including these aspects can help to better explain health behaviour.
