Continuity of care and delivery of ambulatory services to children in community health clinics.

This study assesses how continuity of care influences receipt of preventive care and overall levels of ambulatory care among children and adolescents in community health clinics (CHCs). It is a secondary data analysis of the 1988 Child Health Supplement to the National Health Interview Survey. Of 17,110 children in the sample population, the 1465 who identified CHCs as their routine source of care formed the study population. Continuity of site was defined as identification of a CHC as a source of both routine and sick care, and continuity with a clinician was defined as identification of a specific clinician for sick visits. In bivariate analyses both continuity with the CHC and with a specific clinician were associated with increased levels of preventive care and overall ambulatory care. In logistic regression models, continuity of care was associated with nearly a two-fold increase in the odds of receiving age-appropriate preventive care. Alternatively, insurance status was a better predictor of receipt of overall levels of ambulatory care. We conclude that expanding financial access alone is unlikely to sufficiently improve low-income children's access to Community Health Clinics. Additional emphasis on localizing the delivery of both routine and sick care services in a single site or with a specific clinician may be needed to achieve higher levels of both preventive care and overall ambulatory care.

Single parent mothers and mental health care service use.

BACKGROUND: This paper examines the use of mental health care services by single mothers and married mothers in Canada. METHOD: We employ a secondary data analysis of the 1994-95 National Population Health Survey. RESULTS: Single mothers are significantly more likely to have seen a professional regarding their mental health in the previous 12 months and to use such services more frequently than married mothers. Multivariate analyses show that higher use among single mothers is independent of depression and sociodemographic factors. Further analysis revealed that single mothers have a higher rate of contact with professionals than married mothers and that the relationship between single parent status and frequency of contact is moderated by depression. CONCLUSION: Single mothers are more likely to seek professional help for mental health issues. While qualifying for a diagnosis has some important conditional effects on the frequency of use among single mothers, neither major depression nor controlling for sociodemographic factors accounts for their higher use of services.

Stress, social support and depression in single and married mothers.

BACKGROUND: This study examined the effect of stress and social support on the relationship between single-parent status and depression. METHOD: A secondary data analysis of the 1994-95 National Population Health Survey was conducted. Single and married mothers who participated in the survey were derived from the general sample (N = 2,921). Logistic regression techniques were used to assess the mediating and moderating effects of stress and social support on the relationship between family structure and depression. RESULTS: Bivariate analyses showed that, compared to married mothers, single mothers were more likely to have suffered an episode of depression (12-month prevalence), to report higher levels of chronic stress, more recent life events and a greater number of childhood adversities. Single mothers also reported lower levels of perceived social support, social involvement and frequency of contact with friends and family than married mothers. The results of the multivariate analyses showed that, together, stress and social support account for almost 40% of the relationship between single- parent status and depression. We also found a conditional effect of stress on depression by family structure. Life events were more strongly related to depression in married than in single mothers. CONCLUSIONS: A substantial part of the association between single-parent status and depression can be accounted for by differences in exposure to stress and social support. Our results suggest that it is important to examine multiple sources of stress, as exposure to both distal and proximal stressors were higher among single mothers. Limitations and directions for future research are discussed.

Impact of pain severity and location on health-related quality of life.

Despite evidence that persistent pain affects well-being, little is known about the relationship of the location of pain to psychological and functional well-being. To determine whether patients with musculoskeletal disorders (MSD) are more likely to be depressed and functionally disabled compared to patients with pain at other sites, we conducted a secondary data analysis of the Medical Outcome Study--an observational study of adult outpatients with chronic medical conditions. Of the 3,360 patients who completed the baseline assessment, 1,237 (36.8%) had MSD and 2,123 (63.2%) had no MSD. Among patients in the MSD group, 84.5% reported > or = mild pain as compared to 70% in the no MSD. In multivariate analyses, MSD patients were more likely than non-MSD patients to be depressed (beta coefficient=-1.9, p=0.008) and functionally disabled (beta coefficient=-4.4, p<0.0001). However, the impact of MSD was eliminated after controlling for pain severity. Regardless of the location of pain, pain severity appears to be an important correlate of functional status, both mental and physical.

Correlates of depression in the Korean American elderly: focusing on personal resources of social support.

Today's Korean American elderly are predominantly first-generation immigrants who face stern challenges of acculturation, which is often associated with depression. Social support has been identified as an effective personal resource for alleviating acculturative stress and achieving better mental health outcomes. The purposes of this study were to describe available sources of social support utilized by Korean elders and to examine the relationships among acculturative stress, social support, and depression. In particular, social support was operationalized as an integrative concept encompassing the size of the social network, satisfaction with the support received, and appraisals of the level of social support. This study was a secondary data analysis of an existing survey of 205 elderly Korean immigrants (>or=60 years) in a major metropolitan city on the East coast. Adult children were found to be the main source of support utilized by elders, even when the elder had a living spouse. Hierarchical multiple regression analysis revealed that higher acculturative stress and lower social support were associated with higher depression scores after demographics and health status were controlled for, whereas network size and satisfaction with support were not. Future interventions should address the cultural/social needs of these immigrants, not only by reinforcing their existing social network but also by providing additional support for their family members to prevent social isolation and depression in the population.

Workers' beliefs and expectations affect return to work over 12 months.

BACKGROUND: Successful management of workers on sick leave due to low back pain depends on the identification by the occupational physician of modifiable prognostic factors in the early phase of sick-leave. The prognostic value of factors which influence the course of low back pain and return to work in occupational health care is unclear. METHODS: Secondary data analysis in a cohort of 299 workers on sick leave between 3 and 6 weeks due to low back pain was applied. We investigated the association of a broad set of prognostic indicators related to characteristics of worker, job, low back pain and psychosocial issues on return to work lasting at least 4 weeks (lasting-RTW) and minimally 1 day of first return to work (first-RTW). Relationships were studied using Cox regression analysis and covered a follow-up period of 12 months. The explained variation of the models was also calculated. RESULTS: The median time to return to work using lasting-RTW and first-RTW was 76 and 71 days respectively. In addition to individual analysis of potential predictive factors a backward selection procedure resulted in the following multivariable model: self-predicted timing of return to work, pain intensity, job satisfaction, social support, pain radiation, expectations of treatment succes of the occupational physician. Similar results were found for first-RTW. The explained variance of the multivariate model of lasting-RTW was 18%. CONCLUSIONS: Factors concerning the expectations and beliefs of the worker affected the RTW process. Knowledge of these factors by the occupational physician in the early phase of low back pain and sick-leave may contribute to solutions to promote return to work.

Behavioral problems and the effects of early intervention on eight-year-old children with learning disabilities.

OBJECTIVES: 1) To investigate the comorbidity of verbal and nonverbal learning disability subtypes with several domains of behavior problems among 8-year-old children. 2) To determine whether receipt of an early intervention modified the association between childhood behavior problems and learning disabilities (LD). METHODS: This is a secondary data analysis of the Infant Health and Development Program (IHDP), a randomized clinical trial of an early intervention provided between ages 0 and 3 involving 985 children born low birthweight and premature. The findings are based on a prospective follow-up of these children at 8 years of age. RESULTS: Compared to children without verbal LD (VLD), those with VLD were twice as likely to exhibit clinical levels of total behavior problems and 89% more likely to exhibit externalizing behavior problems. Analysis of specific subscales of behavior revealed significant associations with anxious/depressed and withdrawn behaviors, as well as an increased likelihood of attention problems among children with VLD. No significant association was found between nonverbal LD (NVLD) and any type of behavior problem. Furthermore, there was a significant interaction between VLD and the intervention, in which the odds of internalizing behavior problems were greater among children with VLD. No interaction effect of the intervention occurred for any type of behavior problem among children with NVLD. CONCLUSIONS: These findings provide evidence that distinct differences exist for different learning disability subtypes with regards to behavioral outcomes and the effects of early intervention services among 8-year-old children.

Profile of abused and neglected American Indian children in the Southwest.

From both knowledge gained working in Indian communities and a major data collection program, this article examines child abuse and neglect among the Indian tribes in a southwestern state. The period of study covers 1982 through 1985. The study sample consists of 53 children targeted by the local Indian Health Service Hospital Child Protection Team as being abused and/or neglected. In addition, information on the parents, grandparents and, in a number of cases, great-grandparents are examined. The study is a secondary data analysis of clinic and hospital records and interviews with local community health care providers and tribal officials. The results indicate that alcohol abuse was present in 85% of the neglect cases and in 63% of the abuse cases. In addition, child abuse and neglect occurred simultaneously in 65% of the sample. Child abuse and neglect are found to be part of a larger phenomenon of multiproblem families which raises the issue of intergenerational perpetuation of these problems. The results underscore the importance of interagency cooperation in surveillance, treatment, and prevention, as well as more careful and thorough documentation of record maintenance.

Hot and cold in women's ethnotherapeutics: the American-Mexican West.

The purpose of this paper is to report the current status of hot/cold principles in the ethnotherapeutics of women of southwestern U.S.A., northwestern Mexico. The paper presents a secondary data analysis from three studies, including a data bank of Women's Ethnotherapeutic Agents derived from literature searches, interviews of women in research of Mexican American Grandmothers as Health Care Advisors, and research in the historical roots of the ethnotherapeutic agents used in contemporary domestic medicine. This report presents women's home remedies, what these remedies are believed to do, and the sources of this domestic therapy knowledge. It concentrates on persistence and change in one aspect of the theoretical base of these remedies, their humoral complexional classification. In the analysis of data from these studies, continuation of aspects of the hot/cold theory is demonstrated. It is suggested that the persistence is tacit, with the lack of articulated knowledge of humoral theory today stemming from the content of contemporary remedy books. Instead of arguing either diffusion or independent invention, commonly held ethnophysiological concepts are offered as a possible explanation for the persistence of hot and cold therapy practices.

Bringing social structure back into clinical decision making.

Although research in the past twenty years has resulted in an increasingly sophisticated understanding of clinical decision making processes, the dominant approach in this area of inquiry remains limited. Most studies emphasize normative models of how decisions ought to be made, others attempt to describe physicians' thinking, but few take the social context of decision making systematically into account. Research models typically assume that physicians are autonomous professionals practicing in socially insular clinical settings--an approach that is consistent with classic formulations of the social structure of medical practice, but they ignore 30 years of sociological research on research on patient-physician relationships and major historical changes in the structure of medical practice. Eisenberg's still timely advice to students of clinical decision making--that they need to describe decision making in the context of 'sociologic influences' (including patient, physician and practice setting characteristics)--is expanded in the present discussion. Recent studies are reviewed, highlighting important dimensions of social structure impinging on physicians' decision making. Findings indicate that the process of clinical decision making is likely influenced by patients' age, gender, socioeconomic status, and race, physicians' professional training and experience, as well as by larger structural features of organized clinical settings. Our review of these studies on the social context of clinical decision making, however, reveals major methodological limitations including those inherently imposed by secondary data analysis, normative approaches, written case vignettes, small, non-random samples and the inadequate control of confounding influences. We present a feasible, alternative research strategy, built on a factorial experimental design. Illustrative findings indicate how complex social structural influence on clinical decision making may be disentangled in an unconfounded manner.

The consumption of alcohol by Australian adolescents: a comparison of revenue and expenditure.

AIMS: To estimate (i) Australian government taxation revenue collected from the consumption of alcohol by adolescents and (ii) the amount spent by the government on interventions aimed at educating adolescents about the potential dangers of alcohol use. DESIGN: Secondary data analysis. SETTING: Australia. FINDINGS: Australian adolescents (aged between 12 and 17 years, inclusive) spent approximately US dollars 217 million on alcoholic beverages in 2002, netting the Australian government approximately US dollars 112 million in tax revenue. This resulted in an average of US dollars 195 earned in tax per adolescent drinker. It is estimated that the Government spent approximately US dollars 17 million on adolescent drinking interventions in 2002, equating to an expenditure of about US dollars 10.51 per adolescent on the delivery of alcohol interventions. For every dollar spent on alcohol interventions aimed at adolescents, it is estimated that the government receives around US dollars 7 in alcohol tax revenue. CONCLUSIONS: A substantial disparity exists between the amount of tax revenue received by the Australian government from adolescent drinkers and the overall amount spent in attempting to prevent and relieve some of the problems associated with adolescent problem drinking.

ED visits by older adults for ambulatory care-sensitive and supply-sensitive conditions.

OBJECTIVES: The aim of this study was to examine the effect of advanced age on ED outcomes, including hospitalization for any reason, ambulatory care-sensitive hospitalizations (ACSHs), and supply-sensitive hospitalizations. METHODS: A secondary data analysis of the National Hospital Ambulatory Care Survey was conducted. National estimates of patient visits were obtained using available sampling weights from National Hospital Ambulatory Care Survey, and population estimates were calculated using estimates published by the US Census Bureau. RESULTS: Older adults made 48 million patient visits to ED between 2000 and 2002. Overall, 20.3% was for an ambulatory care-sensitive condition, yielding 5 million ACSH, whereas 62% was for a supply-sensitive condition, yielding 9.5 million supply-sensitive hospitalizations. Residents from nursing homes and patients aged 85 years or older were more likely to be hospitalized for any reason, for ACSH, and for supply-sensitive conditions. CONCLUSIONS: Further research is needed to understand how comorbidity contributes to increasing ED and hospital use among older adults.

Clinical features of head injury patients presenting with a Glasgow Coma Scale score of 15 and who require neurosurgical intervention.

STUDY OBJECTIVE: Emergency physicians are concerned about minor head injury patients who present with a Glasgow Coma Scale (GCS) score of 15 yet require neurosurgical intervention. Our objectives are to determine the accuracy of the Canadian CT Head Rule (CCHR) in this important subset, the prevalence of patients requiring urgent intervention, and their clinical course and possible warning signs. METHODS: We conducted a secondary data analysis of the CCHR study cohorts from 10 hospital emergency departments (EDs). We included head trauma patients with witnessed loss of consciousness, disorientation, or definite amnesia and who presented with an initial GCS score of 15. Records were reviewed and specific variables added to the database. The primary outcome was need for urgent neurosurgical intervention. RESULTS: Among the 4,551 study patients, only 26 (0.6%; 95% confidence interval [CI] 0 to 1.0%) required neurosurgical intervention, and the CCHR identified all 26 cases with 100% sensitivity. Eleven patients required "urgent" craniotomy within 7 days, and of those, 2 patients deteriorated precipitously. These 11 (0.2%; 95% CI 0.1% to 0.3%) cases had additional signs: GCS score decrease within 6 hours (82%), GCS score decrease within 3 hours (73%), confusion (64%), any vomiting (36%), focal temporal blow (36%), restlessness (36%), and severe headache (45%). CONCLUSION: For patients with minor head injury and GCS score of 15, urgent neurosurgical intervention and precipitous deterioration are rare. The CCHR accurately identified all patients requiring neurosurgical intervention. Warning signs that may portend need for urgent intervention include any vomiting, restlessness, any GCS score decrease, severe headache, confusion, and focal temporal blow.

Obesity prevalence among a group of Chicago residents with disabilities.

OBJECTIVE: To examine the prevalence of overweight, obesity, and extreme obesity in a predominantly minority group of adults with disabilities. DESIGN: Cross-sectional study using secondary data analysis. SETTING: Major university medical center. PARTICIPANTS: Adults with physical and cognitive disabilities (N = 306). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Direct measures of height and weight to classify subjects into 3 obesity categories: overweight (body mass index [BMI] range, 25-29.9 kg/m2), obese (BMI range, 30-39.9 kg/m2), and extreme obesity (BMI, > or = 40 kg/m2). RESULTS: People with disabilities, regardless of sex, race and ethnicity, or age, had significantly higher rates of overweight, obesity, and extreme obesity compared with people without disabilities. Extreme obesity (BMI, > or = 40 kg/m2) was approximately 4 times higher among people with disabilities than in the general population (odds ratio = 4.08; 95% confidence interval, 3.50-4.66). There were also substantial differences in obesity prevalence among people with disabilities, using actual measurement data, compared with self-reported data from previously published data sets. CONCLUSIONS: The disparity in excess body weight between people with and without disabilities, particularly in the category of extreme obesity, along with substantial differences in obesity prevalence between actual and self-reported data, show a critical need to better understand why these differences exist.

The relationship between sexual abuse during childhood and parenting outcomes: modeling direct and indirect pathways.

OBJECTIVE: This study examined the association between childhood sexual abuse (CSA) and parenting outcomes including parenting stress, feelings of competence and discipline strategies. Maternal depression and current partner violence were hypothesized to be mediators of the association between CSA and parenting. METHOD: This study is based on secondary data analysis of archived data. The participants were 263 primiparous mothers (107 with a history of CSA and 156 comparison mothers recruited from a prenatal clinic prior to the birth of their first child. Mothers were interviewed twice: once when they were between 28 and 32 weeks gestation and again when their child was between 2 and 4 years of age. During the first interview, women were asked about childhood experiences of sexual abuse. During their second interview, they were asked about current symptoms of pathology and experiences with partner violence and parenting beliefs and practices. RESULTS: Structural Equation Modeling indicated that the relationship between CSA and punitive discipline was mediated by maternal depression and current partner violence. CSA was associated with higher maternal depression and higher partner violence. CSA, maternal depression, and current partner violence were associated with more negative parental perceptions and higher punitive discipline. Once maternal depression and current partner violence were in the model, the relationship between CSA and parenting outcomes was no different from zero. CONCLUSION: These results highlight the risks associated with CSA for parenting outcomes and suggest two potential pathways for this increased risk.

Validation of the timeline follow-back in the assessment of adolescent smoking.

The timeline follow-back instrument (TLFB) is a valid and reliable method of quantifying alcohol use patterns. The use of this instrument has been expanded to assess other behaviors, such as drug use, sexual behavior, binge eating, and panic attacks. Some evidence for the validity and reliability of this assessment instrument has emerged in the area of adult smoking. However, to date, there is no published evidence of its reliability and validity in the assessment of adolescent smoking. The purpose of this study is to present early evidence of the utility of the TLFB to collect information on adolescent smoking behavior. Through secondary data analysis of four studies on adolescent smokers, we examined the associations between the TLFB and measures of dependence, smoking history, respiratory symptoms, and saliva cotinine. Moreover, we examined the stability of the TLFB data across two 15-day time periods. Results provide preliminary evidence of the validity and reliability of the TLFB in the assessment of adolescent smoking. In particular, the TLFB instrument offered important data on the heterogeneity of adolescent smoking patterns beyond a global measure of cigarettes per day, and the reduction of digit bias. Implications of these findings for the assessment of adolescent smoking are discussed.

Effect of pethidine administered during the first stage of labor on the acid-base status at birth.

OBJECTIVE: To evaluate the association between the use of pethidine during the first stage of labor and the presence, type and timing of acidosis in the newborn at birth. STUDY DESIGN: Secondary data analysis of a randomized controlled trial, which included term singleton pregnancies diagnosed with dystocia and requiring active management of labor. Women were randomized to receive either 100 mg of pethidine or placebo. Statistical analyses were performed using chi(2) or Fisher's exact tests for proportions and multiple linear regression for continuous outcomes. RESULTS: Three hundred and eighty-three pregnant women with a valid arterial blood cord sample were included in the final analysis. Lower pH and bicarbonate levels, as well as higher pCO(2) levels were found in the pethidide group. A higher incidence of acidosis was found in the pethidine group (pH<7.12 OR: 8.59 95% C.I. 3.29, 22.46). The highest frequency of acidosis was encountered when pethidine-delivery interval was 5 h. CONCLUSION: Pethidine use during the first stage of labor was associated with an increased risk of acidosis at birth.

Asian ethnicity is associated with reduced pregnancy outcomes after assisted reproductive technology.

OBJECTIVE: To determine whether success rates were similar in Asian and Caucasian women undergoing infertility treatment. DESIGN: Secondary data analysis and multivariate modeling. SETTING: Clinics reporting to the national Society for Assisted Reproductive Technology registry and a university-based clinic. PATIENT(S): Caucasian and self-identified Asian infertile women undergoing IVF. The study included 25,843 Caucasian and 1,429 Asian patients from the national registry; 370 Caucasian and 197 Asian patients were included from the site-specific clinic. INTERVENTION(S): In vitro fertilization. MAIN OUTCOME MEASURE(S): Pregnancy rate and live-birth rate. RESULT(S): Infertile Asian women differed only minimally from their Caucasian counterparts in baseline characteristics and treatment response. Yet Asian women had a decreased clinical pregnancy rate (odds ratio, 0.71; 95% confidence interval 0.64-0.80) and a decreased live-birth rate (odds ratio, 0.69; 95% confidence interval 0.61-0.77). Subsequent multivariate analysis demonstrated that Asian ethnicity was an independent predictor of poor outcome. CONCLUSION(S): After treatment, infertile Asian women have significantly fewer pregnancies than do Caucasian women. Multivariate analysis indicates that this discrepancy cannot be accounted for by differences in baseline characteristics or by response to current therapeutic interventions.
