Living with the mentally ill: Effects on the health and functioning of other household members

Based on data from the National Health Interview Survey Mental Health Supplement, 1989 (NCHS, 1991), this article compares health outcomes for respondents living with someone who is mentally ill (N = 776) with a randomly selected subsample of respondents not living with someone identified as mentally ill (N = 716). When other predictors of health are controlled, sharing a household with a mentally ill person is associated with poorer self-reported physical health, increased risk of reporting some activity limitation, and increased service utilization—both greater risk of hospitalization or visiting a physician, and a greater number of days hospitalized and number of physician visits among those utilizing these services. The severity and duration of mental illness have little effect across health outcome measures. Impaired health and increased utilization of medical care among persons living with someone who is mentally ill suggest hidden costs to individuals, to families of the mentally ill, and to the service system.     

Changes in Ambulatory Health Care Use During the Transition to Young Adulthood

PurposeTo identify changes in ambulatory health care use during the transition from adolescence to young adulthood.MethodsWe analyzed data from health care encounters for adolescents (13–18 year olds) and young adults (19–24 year olds) in the National Ambulatory Medical Care Surveys or National Hospital Ambulatory Medical Care Surveys from 1997 through 2004. We present bivariate analysis of visit characteristics (including clinician specialty and health care setting, primary reason for the visit, and expected source of payment) for young adults as compared with those for adolescents, using weights provided by the National Center for Health Statistics to make national estimates.ResultsAdolescents and young adults used similar number of health care visits annually; however, a greater proportion of ambulatory care for young adults was delivered in emergency departments as compared with adolescents (20% vs. 14%; p < .001), a smaller proportion was delivered to males (27% vs. 46%; p < .001), and a smaller proportion was covered by private health insurance (58% vs. 67%, respectively; p < .001). Among young adults, preventive care was listed as the reason for 40% of non–emergency department visits for females, whereas it accounted for only 10% of visits for males.ConclusionsSignificant changes in ambulatory health care use occur during young adulthood. Improving health care during the transition to adulthood will necessitate attention to health care research and delivery agendas that are relevant to the young adult population.     

Measuring the adequacy of antenatal health care: a national cross-sectional study in Mexico

ObjectiveTo propose an antenatal care classification for measuring the continuum of health care based on the concept of adequacy: timeliness of entry into antenatal care, number of antenatal care visits and key processes of care.MethodsIn a cross-sectional, retrospective study we used data from the Mexican National Health and Nutrition Survey (ENSANUT) in 2012. This contained self-reported information about antenatal care use by 6494 women during their last pregnancy ending in live birth. Antenatal care was considered to be adequate if a woman attended her first visit during the first trimester of pregnancy, made a minimum of four antenatal care visits and underwent at least seven of the eight recommended procedures during visits. We used multivariate ordinal logistic regression to identify correlates of adequate antenatal care and predicted coverage.FindingsBased on a population-weighted sample of 9 052 044, 98.4% of women received antenatal care during their last pregnancy, but only 71.5% (95% confidence interval, CI: 69.7 to 73.2) received maternal health care classified as adequate. Significant geographic differences in coverage of care were identified among states. The probability of receiving adequate antenatal care was higher among women of higher socioeconomic status, with more years of schooling and with health insurance.ConclusionWhile basic antenatal care coverage is high in Mexico, adequate care remains low. Efforts by health systems, governments and researchers to measure and improve antenatal care should adopt a more rigorous definition of care to include important elements of quality such as continuity and processes of care.     

Factors affecting the utilization of prenatal health care services in Jerusalem

Health service utilization patterns during pregnancy were studied among 780 women from selected neighborhoods of Jerusalem who delivered between December 1, 1985 and June 30, 1986. Factors affecting the choice of care-provider, the timing of the first contact with the prenatal care service and the frequency of visits to prenatal care centers were studied with respect to several demographic, socio-economic and needs variables. About one half of the women visited the Family Health Centers, the traditional site for delivery of prenatal care. Forty percent visited their regular doctor during pregnancy while about 30% sought private care. In all, fifty two percent of women consulted more than one source of medical care service during pregnancy. Logistic regression analysis showed that the choice of care was determined by the type of insurance, need factors and education. The timing of the first visit depended on origin, level of education and parity. The frequency of visits was related to the type of insurance and to perceived health.Avi Y.

Mothers' health beliefs and children's clinic visits

This paper reports results from a prospective study of the relationship between mothers' health attitudes and beliefs and their utilization of pediatric clinic services for their children. Attitudinal data were obtained in interviews with a random sample of mothers attending the Children and Youth clinic of a large teaching hospital; data about children's clinic visits during a period of 3 1/2 years subsequent to the interview were abstracted from their medical records. Four aspects of clinic utilization were examined: visits for well-child care; acute-illness visits; accident-related visits; and appointment keeping. Health attitudes were found to be associated with both preventive and illness/accident visits, but in opposite directions. Mothers with an active, interventionist orientation towards health care and mothers who attributed good health and low illness-susceptibility to their children were high users of preventive services and generated few illness/accident visits. Conversely, more passive mothers, and mothers who perceived their children to be in poor health and susceptible to illness, were responsible for fewer well-child and more illness/accident visits. Mothers' agreement with the physician's diagnosis at the index visit was an additional strong predictor of use of well-child services, while disagreement was associated with more visits for illness and accidents. The convenience of appointment times and general satisfaction with the clinic were the best predictors of appointment keeping.These results indicate the importance of distinguishing between different dimensions of health care utilization in studies that attempt to account for this behavior; they also suggest that modification of health attitudes may prove to be an effective way to bring about positive changes in patterns of health services use.Drs.

Paradoxical health care utilization patterns among children in Korea who did not receive mandatory pneumococcal vaccination

BackgroundUnvaccinated children in the National Immunization Program (NIP) are a public health concern. We used Korean national population data to analyze health care utilization patterns of NIP-eligible children and identify the unvaccinated group.MethodsPneumococcal vaccination (PCV) records were reviewed to determine the vaccination status of children born between 2013 and 2015. Children who received three doses or more from a 3 + 1 schedule were defined as vaccinated, while those who had not received any pneumococcal vaccinations were defined as unvaccinated. Corresponding health care utilization records were retrieved from the National Health Insurance Review and Assessment Service. The incidence of combined pneumococcal infections and health care utilization rates were estimated and the proportion of complementary and alternative medicine (CAM) utilization among the total health care utilization records was measured.ResultsIn total, 26,893 (2.1%) of 1,272,685 children remained unvaccinated. The incidence of pneumococcal infection was lower in unvaccinated children, at 10.1 cases (9.8–10.3) per 1000 person-months. However, their health care utilization was significantly lower than that noted for vaccinated children (hospital visit rate: 26.6 (95% confidence interval [CI] 26.5–26.7) vs. 3.2 (3.2–3.3) visits annually), indicating underdetection. CAM treatment was sought at least three times often more in unvaccinated children than in vaccinated children (3.5% vs. 1.1%).ConclusionUnvaccinated children showed significantly lower utilization of overall health care than the vaccinated children; however, a higher preference for CAM was noted among unvaccinated children than among vaccinated children. These differences in care-seeking patterns should be considered when identifying unvaccinated children and providing protection through vaccination programs.     

Family structure, socioeconomic status, and access to health care for children

OBJECTIVE: To test the hypothesis that among children of lower socioeconomic status (SES), children of single mothers would have relatively worse access to care than children in two-parent families, but there would be no access difference by family structure among children in higher SES families. DATA SOURCES: The National Health Interview Surveys of 1993-95, including 63,054 children. STUDY DESIGN: Logistic regression was used to examine the relationship between the child's family structure (single-mother or two-parent family) and three measures of health care access and utilization: having no physician visits in the past year, having no usual source of health care, and having unmet health care needs. To examine how these relationships varied at different levels of SES, the models were stratified on maternal education level as the SES variable. The stratified models adjusted for maternal employment, child's health status, race and ethnicity, and child's age. Models were fit to examine the additional effects of health insurance coverage on the relationships between family structure, access to care, and SES. PRINCIPAL FINDINGS: Children of single mothers, compared with children living with two parents, were as likely to have had no physician visit in the past year; were slightly more likely to have no usual source of health care; and were more likely to have an unmet health care need. These relationships differed by mother's education. As expected, children of single mothers had similar access to care as children in two-parent families at high levels of maternal education, for the access measures of no physician visits in the past year and no usual source of care. However, at low levels of maternal education, children of single mothers appeared to have better access to care than children in two-parent families. Once health insurance was added to adjusted models, there was no significant socioeconomic variation in the relationships between family structure and physician visits or usual source of care, and there were no significant disparities by family structure at the highest levels of maternal education. There were no family structure differences in unmet needs at low maternal education, whereas children of single mothers had more unmet needs at high levels of maternal education, even after adjustment for insurance coverage. CONCLUSIONS: At high levels of maternal education, family structure did not influence physician visits or having a usual source of care, as expected. However, at low levels of maternal education, single mothers appeared to be better at accessing care for their children. Health insurance coverage explained some of the access differences by family structure. Medicaid is important for children of single mothers, but children in two-parent families whose mothers are less educated do not always have access to that resource. Public health insurance coverage is critical to ensure adequate health care access and utilization among children of less educated mothers, regardless of family structure.     

Frailty Predicts Increased Health Care Utilization Among Community-Dwelling Older Adults: A Longitudinal Study in China

ObjectivesFrailty, a multidimensional syndrome characterized by vulnerability to stressors, is an emerging public health priority with high prevalence in older adults. Frailty has been identified to predictive negative health outcomes, yet quantified evidence regarding its effect on health care systems is scarce. This study examines how frailty affects health care utilization, and explores whether these associations varied by gender.DesignCohort study with a 2-year follow-up.Settingand Participants: Data were derived from 2 waves (2011 and 2013) of the China Health and Retirement Longitudinal Study, and 3119 community-dwelling participants aged ≥60 years were analyzed.MethodsFrailty was assessed by a validated frailty phenotype scale, and measures for health care utilization were self-reported. Panel data approach of mixed-effects regression models was used to examine the associations.ResultsLongitudinal results demonstrated that compared with robustness, prefrailty and frailty were both significantly associated with increased likelihood of outpatient visit, inpatient visit, and inpatient length of stay, even after adjusting for multimorbidity in multivariate analyses (all P < .05). Every 1-component increase in frailty was also found to significantly increase the risk for health care utilization [any outpatient visit: adjusted odds ratio (OR) 1.30, 95% confidence interval (CI) 1.14–1.48; number of outpatient visits: adjusted incident rate ratio (IRR) 1.34, 95% CI 1.18–1.53; any inpatient visit: adjusted OR 1.44, 95% CI 1.22–1.71; number of inpatient visits: adjusted IRR 1.40, 95% CI 1.20–1.62; inpatient length of stay: adjusted IRR 1.50, 95% CI 1.18–1.92]. The preceding associations were similarly observed irrespective of gender.Conclusions and ImplicationsFrailty is a significant predictor for increased health care utilization among community-dwelling older adults. These findings have important implications for routine clinical practice and public health investment. Early screening and intervention for potentially modifiable frailty could translate into considerable savings for households and health care systems.

Adolescents’ and Young Adults’ Routine Care Use: The Role of Their Mothers’ Care Use Behaviors

Purpose

Little is known whether mothers' own care use is differentially associated with their adolescents’ routine care use by gender. The main purpose of this study is to examine whether mothers’ healthcare use prospectively predicts their adolescents’ routine care use stratified by gender, after controlling for predisposing (child's age, race/ethnicity, region of residence, urbanicity, and mother's age at child's birth), enabling (mother's education, adolescent and mother health insurance), and need (child health status) factors.

A comparison of the information obtained in a health survey by interview with primary care registries]

To estimate the levels of underreporting of medical visits and to compare the reporting of chronic restrictive diseases, 203 individuals who had been visited in a Primary Health Center were interviewed in the period of two weeks following the medical visit. Underreporting of a medical visit was identified in 31 (15.3%) of the users. The level of underreporting was not related with age, sex, education or socioeconomic status. Reporting of chronic restrictive illness was compared with the information recorded in the user's medical record. The highest global agreement (91.6%) was observed for hypertensive disease (kappa index = 0.71), while the lowest agreement was found for chronic back pain (global agreement = 77.8% and kappa index = 0.14). Since underreporting of medical visits was moderate, the results suggest that this question can be used for the analysis of social differences in the access to health services. Nevertheless, estimation of the prevalence of chronic limiting conditions in a health interview survey should be done with great caution.     

The impact of preventive health behaviour and social factors on visits to the doctor

Background

The aim of this study is to examine the joint impact of preventive health behavior (PHB) and social and demographic factors on the utilization of primary and secondary medical care under a universal health care system, as measured by visits to the doctor, who were categorized as either a General Practitioner (GP) or Specialist Doctor (SD).

Methods

An ordered probit model was utilized to analyze data obtained from the 2009 Israeli National Health Survey. The problem of endogeneity between PHB factors and visits to GP was approached using the two-stage residuals inclusion and instrumental variables method.

Results

We found a positive effect of PHB on visits to the doctor while the addition of the PHB factors to the independent variables resulted in important changes in explaining visits to GP (in values of the estimates, in their sign, and in their statistical significance), and only in slight changes for visits to SD. A 1% increase in PHB factors results in increasing the probability to visit General Practitioner in the last year in 0.6%. The following variables were identified as significant in explaining frequency of visits to the doctor: PHB, socio-economic status (pro-poor for visits to GP, pro-rich for visits to SD), location (for visits to SD), gender, age (age 60 or greater being a negative factor for visits to GP and a positive factor for visits to SD), chronic diseases, and marital status (being married was a negative factor for visits to GP and a positive factor for visits to SD).

Conclusions

There is a need for allowing for endogeneity in examining the impact of PHB, social and demographic factors on visits to GP in a population under universal health insurance.For disadvantaged populations with low SES and those living in peripheral districts, the value of IndPrev is lower than for populations with high SES and living in the center of the country. Examining the impact of these factors, significant differences in the importance and sometimes even in the sign of their influence on visits to different categories of doctors - GP and SD, are found.

     

Peer Reviewed: Social Disparities in Dental Insurance and Annual Dental Visits Among Medically Insured Patients With Diabetes: the Diabetes Study of Northern California (DISTANCE) Survey

Introduction

People with diabetes are at increased risk of periodontal disease and tooth loss. Healthy People 2010 set a goal that 71% or more of people with diabetes should have an annual dental exam.

Methods

We assessed dental insurance and annual dental visits among dentate respondents from the Diabetes Study of Northern California (DISTANCE) Survey cohort (N = 20,188), an ethnically stratified, random sample of patients with diabetes aged 30 to 75 years receiving medical care from Kaiser Permanente Northern California. We calculated predicted probabilities for an annual dental visit (PPADV) by using regression models that incorporated age, sex, education level, annual household income, and self-reported race/ethnicity, stratified by whether the respondent had dental insurance.

Results

Among 12,405 dentate patients, 9,257 (75%) had dental insurance. Annual dental visits were reported by 7,557 (82%) patients with dental insurance and 1,935 (61%) patients without dental insurance. The age-sex adjusted odds ratio for an annual dental visit was 2.66 (95% confidence interval, 2.33-3.03) for patients with dental insurance compared to those without dental insurance. For patients with dental insurance, the PPADV was 71% or more for all except those with the lowest household income. In contrast, for those without dental insurance, the PPADV was less than 71% for all except those with the most education or the highest income. We found some racial/ethnic subgroups were more likely than others to take advantage of dental insurance to have an annual dental visit.

Conclusions

Patients with diabetes in this managed care population who lacked dental insurance failed to meet the Healthy People 2010 goal for an annual dental visit. An increased effort should be made to promote oral health among people with diabetes.     

Factors associated with use of preventive dental and health services among U.S. adolescents

Purpose: To examine adolescents’ use of preventive medical and dental services and its relationship to demographic characteristics and other variables reflecting access to and need for care.

Methods: Self- and parent-reported data from a sample of 5644 adolescents aged 11 to 21 years from the National Longitudinal Study of Adolescent Health (Add Health). Variables studied include the influence of both the adolescents’ demographic and socioeconomic characteristics (age, race/ethnicity, place of birth, acculturation, insurance status, and perception of health), as well as those of their parents (race/ethnicity, income, level of education, place of birth) on their lifetime use and use within the past year of medical and dental services. Bivariate and logistic regression analyses were conducted using SAS and SUDAAN.

Results: Approximately 32% of respondents had not had a physical examination in the year before the survey, and the same percentage had not had a dental examination. Approximately 2% reported never having had either a physical or a dental examination. Logistic regression reveals that lack of insurance, low family income, and low parental education level are significantly associated with the lack of preventive medical care. Lack of an annual dental visit was associated with male gender; black, Hispanic, or mixed race/ethnicity; and lack of insurance. Never having had a dental visit was the only dependent variable found to be associated with place of birth.

Conclusions: Health insurance and family income are most consistently related to adolescents’ use of preventive medical and dental care. However, the relationship between lack of dental care and place of birth emphasizes the need to improve access to dental services for immigrant teens. These findings are particularly relevant as states design systems of care for adolescents under the State Children’s Health Insurance Program.     

The importance of health insurance as a determinant of cancer screening: evidence from the Women's Health Initiative

BACKGROUND: Amid current changes in health care access across the United States, the importance of health insurance status and insurance type relative to demographic, actual, and perceived health variables as determinants of screening for breast, colorectal, and cervical cancer is uncertain. This analysis evaluates the hypothesis that health insurance independently predicts cancer screening in the Women's Health Initia tive Observational Study cohort. METHODS: Questionnaire data from 55,278 women en rolled in the Women's Health Initiative Observational Study between September 1994 and February 1997 were analyzed by multiple logistic regression to identify predictors of self-reported mammography within 2 years, Pap smear within 3 years, and stool guaiac or flexible sigmoidoscopy within 5 years. RESULTS: Positive determinants of reporting cancer screening were age, ethnic origin, household income, educational level, family history of cancer, having a usual care provider, time since last provider visit, and insurance status and type. Smoking, diabetes, and, among older women, prior cardiovascular events were negative determinants of cancer screening. Among women younger than 65, lacking health insurance or having fee-for-service insurance was strongly associated with failure to report cancer screening, independently of having or using a usual care provider and of demographics, self-perceived health, and health characteristics. Among women 65 and older, those with Medicare alone were less likely, whereas those with Medicare + prepaid insurance were more likely, to report cancer screening. CONCLUSIONS: In the Women's Health Initiative Obser vational Study, a large, diverse group of older women, health insurance type and status were among the most important determinants of cancer screening indepen dent of demographics, chronic health conditions, and self-perceived health characteristics.     

Modeling the effect of insurance on health expenditures in the People''s Republic of China.

A pilot study was undertaken in two rural counties in Sichuan Province to determine the feasibility of offering health insurance to peasant families. Models of per capital inpatient and outpatient health care expenditures were developed using self-reported utilization from a survey of 880 households, supplemented by cost and utilization data from the providers in the counties. Expenditures at a facility were modeled as a function of level of insurance in three parts: (1) as the product of the probability of any use, (2) the expected number of visits given any use, and (3) the cost per visit at the facility. Output from the model for representative insurance plans is presented.     

Impacts of Medicaid Expansion on Health Insurance and Coverage Transitions among Women with or at Risk for HIV in the United States

BackgroundAs employment, financial status, and residential location change, people can gain, lose, or switch health insurance coverage, which may affect care access and health. Among Women's Interagency HIV Study participants with HIV and participants at risk for HIV attending semiannual visits at 10 U.S. sites, we examined whether the prevalence of coverage types and rates of coverage changes differed by HIV status and Medicaid expansion in their states of residence.MethodsGeocoded addresses were merged with dates of Medicaid expansion to indicate, at each visit, whether women lived in Medicaid expansion states. Age-adjusted rate ratios (RRs) and rate differences of self-reported insurance changes were estimated by Poisson regression.ResultsFrom 2008 to 2018, 3,341 women (67% Black, 71% with HIV) contributed 43,329 visits at aged less than 65 years (27% under Medicaid expansion). Women with and women without HIV differed in their proportions of visits at which no coverage (14% vs. 19%; p < .001) and Medicaid enrollment (61% vs. 51%; p < .001) were reported. Women in Medicaid expansion states reported no coverage and Medicaid enrollment at 4% and 69% of visits, respectively, compared with 20% and 53% of visits for those in nonexpansion states. Women with HIV had a lower rate of losing coverage than those without HIV (RR, 0.81; 95% confidence interval [CI], 0.70 to 0.95). Compared with nonexpansion, Medicaid expansion was associated with lower coverage loss (RR, 0.62; 95% CI, 0.53 to 0.72) and greater coverage gain (RR, 2.32; 95% CI, 2.02 to 2.67), with no differences by HIV status.ConclusionsBoth women with HIV and women at high risk for HIV in Medicaid expansion states had lower coverage loss and greater coverage gain; therefore, Medicaid expansion throughout the United States should be expected to stabilize insurance for women and improve downstream health outcomes.
