Rates Of Primary Care Visits Research Articles

Health Care Use by Muslim Patients During Ramadan.

Health care utilization during Ramadan has not been examined in the United States. A retrospective review of billing and electronic health record data for Muslims (n = 2,919) and non-Muslims (n = 184,803) in primary care practices in Eastern Massachusetts. Muslim patients were younger, less educated, less often commercially insured, more likely to have Medicare, and less likely to be primary English speakers (p < .0001 for all comparisons). In multivariate models, during Ramadan, Muslims, compared with non-Muslims, had a higher rate of primary care visits (incidence rate ratio [IRR], 1.06; 95% confidence interval [CI], 1.01-1.11), emergency department visits (IRR, 1.60; 95% CI, 1.34-1.91), and hospitalizations (IRR, 1.18; 95% CI, 1.03-1.34). Important demographic differences exist between Muslim and non-Muslim patients. Muslims, compared with non-Muslims, had higher health care utilization during Ramadan.

Healthcare Utilization After a Children's Health Insurance Program Expansion in Oregon.

The future of the Children's Health Insurance Program (CHIP) is uncertain after 2017. Survey-based research shows positive associations between CHIP expansions and children's healthcare utilization. To build on this prior work, we used electronic health record (EHR) data to assess temporal patterns of healthcare utilization after Oregon's 2009-2010 CHIP expansion. We hypothesized increased post-expansion utilization among children who gained public insurance. Using EHR data from 154 Oregon community health centers, we conducted a retrospective cohort study of pediatric patients (2-18 years old) who gained public insurance coverage during the Oregon expansion (n = 3054), compared to those who were continuously publicly insured (n = 10,946) or continuously uninsured (n = 10,307) during the 2-year study period. We compared pre-post rates of primary care visits, well-child visits, and dental visits within- and between-groups. We also conducted longitudinal analysis of monthly visit rates, comparing the three insurance groups. After Oregon's 2009-2010 CHIP expansions, newly insured patients' utilization rates were more than double their pre-expansion rates [adjusted rate ratios (95 % confidence intervals); increases ranged from 2.10 (1.94-2.26) for primary care visits to 2.77 (2.56-2.99) for dental visits]. Utilization among the newly insured spiked shortly after coverage began, then leveled off, but remained higher than the uninsured group. This study used EHR data to confirm that CHIP expansions are associated with increased utilization of essential pediatric primary and preventive care. These findings are timely to pending policy decisions that could impact children's access to public health insurance in the United States.

Sex and age differences in the early identification and treatment of alcohol use: a population-based study of patients with alcoholic cirrhosis.

To estimate sex differences in health-care utilization among harmful/hazardous drinkers in the period before alcoholic cirrhosis diagnosis, and estimate sex differences in the extent to which alcohol use and brief alcohol interventions were documented for these individuals compared with a control cohort. Retrospective study using linked general practice and hospital admissions data in England. Three hundred and fifty-seven general practitioner (GP) practices in England. A total of 2479 individuals with alcoholic cirrhosis (mean age at diagnosis=56 years), of whom 67% were men; and 24,790 controls without the disease. Rates of primary care visits and hospital admissions prior to the diagnosis of alcoholic cirrhosis for men and women, and the proportion of men and women with alcohol consumption and/or alcohol brief intervention documented in their medical record. Compared with the general population, patients with alcoholic cirrhosis used primary and secondary health-care services more frequently in the years leading up to their diagnosis. In the years prior to diagnosis, men used primary and secondary health-care services more than did women (P for sex interaction P<0.0001). Men were more likely than women to have their alcohol use recorded [odds ratio (OR) men=1.96, 95% confidence interval (CI)=1.7-2.3; women=1.63, 95% CI=1.4-1.8, P for sex interaction P<0.0017]. By contrast, alcohol interventions were recorded more commonly among women (OR men=4.3, 95% CI=3.7-4.9; women=5.8, 95% CI=4.7-6.9, P for sex interaction=0.07), although less common with increasing age (P for age interaction=0.009). In the United Kingdom, prior to alcoholic cirrhosis diagnosis, excess health-care utilization is higher in men than women and men are more likely than women to have their alcohol use recorded. However, women appear to be more likely than men to receive alcohol brief interventions.

Community Health Center Use After Oregon's Randomized Medicaid Experiment.

There is debate about whether community health centers (CHCs) will experience increased demand from patients gaining coverage through Affordable Care Act Medicaid expansions. To better understand the effect of new Medicaid coverage on CHC use over time, we studied Oregon's 2008 randomized Medicaid expansion (the "Oregon Experiment"). We probabilistically matched demographic data from adults (aged 19-64 years) participating in the Oregon Experiment to electronic health record data from 108 Oregon CHCs within the OCHIN community health information network (originally the Oregon Community Health Information Network) (N = 34,849). We performed intent-to-treat analyses using zero-inflated Poisson regression models to compare 36-month (2008-2011) usage rates among those selected to apply for Medicaid vs not selected, and instrumental variable analyses to estimate the effect of gaining Medicaid coverage on use. Use outcomes included primary care visits, behavioral/mental health visits, laboratory tests, referrals, immunizations, and imaging. The intent-to-treat analyses revealed statistically significant differences in rates of behavioral/mental health visits, referrals, and imaging between patients randomly selected to apply for Medicaid vs those not selected. In instrumental variable analyses, gaining Medicaid coverage significantly increased the rate of primary care visits, laboratory tests, referrals, and imaging; rate ratios ranged from 1.27 (95% CI, 1.05-1.55) for laboratory tests to 1.58 (95% CI, 1.10-2.28) for referrals. Our results suggest that use of many different types of CHC services will increase as patients gain Medicaid through Affordable Care Act expansions. To maximize access to critical health services, it will be important to ensure that the health care system can support increasing demands by providing more resources to CHCs and other primary care settings.

Effect of Pediatric Behavioral Health Screening and Colocated Services on Ambulatory and Inpatient Utilization.

The study sought to determine the impact of a pediatric behavioral health screening and colocation model on utilization of behavioral health care. In 2003, Cambridge Health Alliance, a Massachusetts public health system, introduced behavioral health screening and colocation of social workers sequentially within its pediatric practices. An interrupted time-series study was conducted to determine the impact on behavioral health care utilization in the 30 months after model implementation compared with the 18 months prior. Specifically, the change in trends of ambulatory, emergency, and inpatient behavioral health utilization was examined. Utilization data for 11,223 children ages ≥4 years 9 months to <18 years 3 months seen from 2003 to 2008 contributed to the study. In the 30 months after implementation of pediatric behavioral health screening and colocation, there was a 20.4% cumulative increase in specialty behavioral health visit rates (trend of .013% per month, p=.049) and a 67.7% cumulative increase in behavioral health primary care visit rates (trend of .019% per month, p<.001) compared with the expected rates predicted by the 18-month preintervention trend. In addition, behavioral health emergency department visit rates increased 245% compared with the expected rate (trend .01% per month, p=.002). After the implementation of a behavioral health screening and colocation model, more children received behavioral health treatment. Contrary to expectations, behavioral health emergency department visits also increased. Further study is needed to determine whether this is an effect of how care was organized for children newly engaged in behavioral health care or a reflection of secular trends in behavioral health utilization or both.

Association of visit-to-visit variability of hemoglobin A1c and medication adherence.

Medication nonadherence is widespread, but there are few efficient means of detecting medication nonadherence at the point of care. Visit-to-visit variability in clinical biomarkers has shown inconsistent efficiency to predict medication adherence. To examine the performance of visit-to-visit variability (VVV) of hemoglobin A1c to predict nonadherence to antidiabetic medications. In this cross-sectional study using a clinical and administrative database, adult members of a managed care plan at a safety-net medical center from 2008 to 2012 were included if they had ≥ 3 noninsulin antidiabetic prescription fills within the same class and ≥ 3 A1c measurements between the first and last prescription fills. The independent variable was VVV of A1c (within-subject standard deviation of A1c), and the dependent variable was medication adherence (defined by medication possession ratio) determined from pharmacy claims. Unadjusted and adjusted multivariate logistic regression models were created to examine the relationship between VVV of A1c and medication nonadherence. Receiver-operating characteristic (ROC) curves assessed the performance of the adjusted model at discriminating adherence from nonadherence. Among 632 eligible subjects, mean A1c was 7.7% ± 1.3%, and 83% of the sample was nonadherent to antidiabetic medications. Increasing quintiles of VVV of A1c and medication nonadherence were both associated with increased within-subject mean A1c and younger subject age. The logistic regression model (adjusted for age, sex, race/ethnicity, within-subject mean A1c, number of A1c measurements, number of days between the first and last antidiabetic medication prescription fills, and rate of primary care visits during the study period) showed a nonsignificant association of VVV of A1c and medication nonadherence (OR = 1.19, 95% CI = 0.42-3.38 for the highest quintile of VVV). Adding VVV of A1c to a model including age, sex, and race only modestly improved the C-statistic of the ROC curve from 0.6786 to 0.7064. VVV of A1c is not a robust predictor of antidiabetic medication nonadherence. Further innovation is needed to develop novel methods of detecting nonadherence.

Use of emergency departments and primary care visits for asthma related conditions in the 3 years following an asthma education program

Background: This study examines changes in Primary Care Visits (PCVs) and Emergency Department Visits (EDVs) among 1918 patients with asthma who attended either two visits, one visit or were no-show referrals at the Dr. Patrick Gill Asthma Education Center (AEC) in Charlottetown Prince Edward Island (PEI) between January 1, 2003 and March 31, 2008 compared to 2799 controls selected from a list of PEI asthma patients developed for the Canadian Chronic Disease Surveillance System (CCDSS). Methods: Hurdle regression was used to model counts of PCVs and negative binomial models were used to model counts of EDVs at 12 months prior to AEC contact and 0–1, >1 to 2 and >2 to 3 years after AEC contact. The PEI Research Board approved the project. Results: No-show referrals had a significant increase in pediatric EDVs and PCVs in the first year after referral. The higher rates of PCVs and EDVs prior to contact with the AEC in patients referred to the AEC were reduced after contact with the AEC, although they remained significantly higher than the CCDSS controls. Conclusions: Compared to patients who attended the AEC, referred patients who did not attend the AEC did not achieve similar reductions in pediatric EDVs and PCVs in the first year after referral.

Low Rates of Influenza Immunization in Young Children Under Ontario’s Universal Influenza Immunization Program

To determine physician-administered influenza vaccine coverage for children aged 6 to 23 months in a jurisdiction with a universal influenza immunization program during 2002-2009 and to describe predictors of vaccination. By using hospital records, we identified all infants born alive in Ontario hospitals from April 2002 through March 2008. Immunization status was ascertained by linkage to physician billing data. Children were categorized as fully, partially, or not immunized depending on the number and timing of vaccines administered. Generalized linear mixed models determined the association between immunization status and infant, physician, and maternal characteristics. Influenza immunization was low for the first influenza season of the study period (1% fully immunized during the 2002-2003 season), increased for the following 3 seasons (7% to 9%), but then declined (4% to 6% fully immunized during the 2006-2007 to 2008-2009 seasons). Children with chronic conditions or low birth weight were more likely to be immunized. Maternal influenza immunization (adjusted odds ratio 4.31; 95% confidence interval 4.21-4.40), having a pediatrician as the primary care practitioner (adjusted odds ratio 1.85; 95% confidence interval 1.68-2.04), high visit rates, and better continuity of care were all significantly associated with full immunization, whereas measures of social disadvantage were associated with nonimmunization. Low birth weight infants discharged from neonatal care in the winter were more likely to be immunized. Influenza vaccine coverage among children aged 6 to 23 months in Ontario is low, despite a universal vaccination program and high primary care visit rates. Interventions to improve coverage should target both physicians and families.

Primary Care Physician Supply and Children's Health Care Use, Access, and Outcomes: Findings From Canada

To describe the relationship of primary care physician (PCP) supply for children and measures of health care access, use, and outcomes. We conducted a population-based, cross-sectional study of all Ontario children from 2003 to 2005. We used health administrative data to calculate county-level supply (full-time equivalents [FTEs]) of PCPs. We modeled the relationship of supply to (1) recommended primary care visits, (2) emergency department (ED) use, and (3) ambulatory care-sensitive condition admissions and adjusted for neighborhood income. We used population-based surveys to describe access. The county-level PCP supply ranged from 1720 to 4720 children per FTE. Of the children, 45.4% live in the highest-supply areas (<2000 children per FTE) and 8% in the lowest-supply areas (>3000 children per FTE). Compared with high-supply counties, the lowest had significantly lower rates of primary care visits (2716 vs 7490 per 1000) and higher proportions of newborns without early follow-care (58.2% vs 14.5%). Low-supply areas had higher rates of ED visits (440 vs 179 per 1000) and admissions. A stepwise gradient existed for every decrease in supply for most measures. Self-reported access barriers were most evident in areas with >3500 children per FTE (32.8% without a physician). Under universal insurance there are differences in access to, and outcomes of, primary care related to local physician supply after controlling for neighborhood income. The most pronounced effect is on primary and ED care use, but there are implications for acute and chronic disease control. Physician distribution is a critical issue to address in policies to improve access to care.

Respiratory disease and climatic seasonality in children under 15 years old in a town in the Brazilian Amazon

To analyze the climatic seasonality of primary care visits for respiratory disease (RD) in children less than 15 years old. This was a descriptive, epidemiological study based on data from the municipal records of primary care events from basic healthcare centers for the period 2004-2005, for the municipality of Tangará da Serra (MT), Brazil. Population estimates were obtained from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística, IGBE), and data on temperature and relative humidity of the air, from the National Meteorology Institute (Instituto Nacional de Meteorologia, INMET). Mean rates of primary care visits for RD were calculated according to sex, age group and anatomic location of complaint. The ratio of dry season to rainy season visits was calculated according to anatomic location of the RD. Data were analyzed using Epi-Info 3.2, testing differences between proportions using the chi-square test to a significance level of 5%. Male children had an almost 50% greater (37.3/25.0) rate of primary care visits for diseases of the lower respiratory tract than did females. The rates of primary care visits due to RD in children under 15 years of age varied as age increased, varying from 457.7 per thousand of children less than 1 year of age to 133.5 per thousand in the 10 to 14 years-of-age group. During the dry season there were an average of 21% (4,148/5,231) fewer visits for RD (p = 0.000). Peaks in numbers of visits were observed during the months of March and August, being more accentuated in March, which is the wet season in the region. Primary care visits for RD, especially those due to upper airway diseases, are related to the rainy season in this municipality.

Doença respiratória e sazonalidade climática em menores de 15 anos em um município da Amazônia brasileira

OBJETIVO: Analisar a sazonalidade climática dos atendimentos ambulatoriais por doença respiratória (DR) em menores de 15 anos. MÉTODOS: Estudo epidemiológico descritivo, realizado com dados dos Registros de Ocorrências Ambulatoriais das unidades básicas de saúde referentes ao período 2004-2005, do município de Tangará da Serra (MT). As estimativas populacionais foram obtidas do Instituto Brasileiro de Geografia e Estatística (IBGE), e os dados de umidade relativa do ar e temperatura, do Instituto Nacional de Meteorologia (INMET). Foram construídas taxas médias de atendimento ambulatorial por DR segundo sexo, faixa etária e localização anatômica. Calculou-se a razão seca/chuva dos atendimentos de acordo com a localização anatômica da DR. Utilizou-se o Epi-Info 3.2 para análise dos dados, com as diferenças de proporção testadas através do teste do qui-quadrado, ao nível de significância de 5%. RESULTADOS: Indivíduos do sexo masculino tiveram taxa quase 50% maior (37,3/25,0) de atendimentos ambulatoriais por doenças das vias aéreas inferiores que os do sexo feminino. As taxas de atendimentos ambulatoriais por DR em menores de 15 anos apresentaram variação com o aumento da idade, passando de 457,7‰ nos menores de 1 ano de idade para 133,5‰ no grupo de 10 a 14 anos. Os atendimentos por DR foram em média 21% menos freqüentes(4.148/5.231) no período seco (p = 0,000). Observou-se picos de atendimento nos meses de março e agosto, mais acentuados em março, período chuvoso na região. CONCLUSÃO: Os atendimentos ambulatoriais por DR, especialmente por doenças das vias aéreas superiores, estão relacionados ao período chuvoso no município.

Two Commentaries: Managed Care for Children: Effect on Access to Care and Utilization of Health Services

The rapid trend toward enrolling children in managed care has occurred largely without conclusive evidence about the effects of these arrangements on two important aspects of care: access and utilization. Although the effect of managed care on these measures has been studied more widely in the adult population, the results may not be applicable to children, who have unique health care needs centering around prevention and early treatment of acute illnesses to avoid long-term health problems. Moreover, several methodological challenges make it difficult to evaluate the impact of managed care on health care access and utilization in general. This article reviews what is known about the effect of managed care on access to health services, as well as utilization of hospital care, emergency department (ED) visits, primary care services, and specialty services for the pediatric population. In each area, findings from privately insured children and Medicaid enrollees are considered separately. There is little conclusive evidence on the effect of managed care on access to and utilization of pediatric health services. A recurring theme is that the effect of managed care is dependent on several factors, including whether providers assume financial risk through capitated reimbursements or retain fee-for-service payments; the comprehensiveness of benefits offered by health plans; and the level of cost sharing required of families. Among privately insured children, for example, managed care usually has been associated with higher primary care visit rates, though the benefit of managed care is reduced when fee-for-service plans cover preventive care and require minimal or no cost sharing for these services. Among Medicaid recipients, studies suggest that managed care is more likely to be associated with a decrease in preventive visits when provider payments are capitated. Attempts to decipher effects by health plan type are made more difficult by the rapid evolution of both managed care and fee-for-service plans, which often blurs the distinction between these two entities. Nonetheless, in some areas, managed care does appear to have an identifiable effect on pediatric health services. For Medicaid recipients, managed care has been associated with decreased emergency department use and decreased access to specialty care for chronically ill children. As enrollment of children in managed care plans increases, the need continues for methodologically sound studies evaluating the effect of these arrangements on the delivery of pediatric health services and on health outcomes.

The Statistics of the Samaritan Free Hospital

<h3>Background:</h3> There were large disruptions to health care services after the onset of the COVID-19 pandemic. We sought to describe the extent to which pandemic-related changes in service delivery and access affected use of primary care for children overall and by equity strata in the 9 months after pandemic onset in Manitoba and Ontario. <h3>Methods:</h3> We performed a population-based study of children aged 17 years or less with provincial health insurance in Ontario or Manitoba before and during the COVID-19 pandemic (Jan. 1, 2017–Nov. 28, 2020). We calculated the weekly rates of in-person and virtual primary care well-child and sick visits, overall and by age group, neighbourhood material deprivation level, rurality and immigrant status, and assessed changes in visit rates after COVID-19 restrictions were imposed compared to expected baseline rates calculated for the 3 years before pandemic onset. <h3>Results:</h3> Among almost 3 million children in Ontario and more than 300 000 children in Manitoba, primary care visit rates declined to 0.80 (95% confidence interval [CI] 0.77–0.82) of expected in Ontario and 0.82 (95% CI 0.79–0.84) of expected in Manitoba in the 9 months after the onset of the pandemic. Virtual visits accounted for 53% and 29% of visits in Ontario and Manitoba, respectively. The largest monthly decreases in visits occurred in April 2020. Although visit rates increased slowly after April 2020, they had not returned to prerestriction levels by November 2020 in either province. Children aged more than 1 year to 12 years experienced the greatest decrease in visits, especially for well-child care. Compared to prepandemic levels, visit rates were lowest among rural Manitobans, urban Ontarians and Ontarians in low-income neighbourhoods. <h3>Interpretation:</h3> During the study period, the pandemic contributed to rapid, immediate and inequitable decreases in primary care use, with some recovery and a substantial shift to virtual care. Postpandemic planning must consider the need for catch-up visits, and the long-term impacts warrant further study.
