Background and Objectives: Metabolic monitoring is important for children taking antipsychotic medication, given the risk for increased BMI, impaired glucose metabolism, and hyperlipidemia. The purpose was to examine the influence of provider specialty on the receipt of metabolic monitoring. Specifically, differences in the receipt of recommended care when a child receives outpatient care from a primary care provider (PCP), a mental health provider with prescribing privileges, or both was examined., Methods: Medicaid enrollment and health care and pharmacy claims data from 2 states were used in the analyses. Providers were assigned to specialties by using a crosswalk of the National Provider Identifier numbers to specialty type. A total of 41 078 children were included., Results: For both states, 61% of children saw ≥1 provider type and had adjusted odds ratios for receiving metabolic monitoring that were significantly higher than those of children seeing PCPs only. For example, children seeing a PCP and a mental health provider with prescribing privileges during the year had adjusted odds of receiving metabolic monitoring that were 42% higher than those seeing a PCP alone ( P < .001)., Conclusions: Shared care arrangements significantly increased the chances that metabolic monitoring would be done. For states, health plans, and clinicians to develop meaningful quality improvement strategies, identifying the multiple providers caring for the children and potentially responsible for ordering tests consistent with evidence-based care is essential. Provider attribution in the context of shared care arrangements plays a critical role in driving quality improvement efforts., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2021 by the American Academy of Pediatrics.)

Objective: Evidence suggests that spatial accessibility to primary care is a contributing factor to appropriate health care utilization, with limited primary care access resulting in avoidable hospitalizations and emergency department visits which are burdensome on individuals and our health care system. Limited research, however, has examined the effects on children., Methods: We evaluated associations of spatial accessibility to primary care on health care utilization among a sample of 16,709 children aged 0 to 3 years in Philadelphia who were primarily non-White and publicly insured. Log-Poisson models with generalized estimating equations were used to estimate incidence rate ratios (RR) and 95% confidence intervals (CI), while accounting for 3 levels of clustering (within individual, within primary care practice, within neighborhood)., Results: In age-adjusted models, the lowest level of spatial accessibility was associated with 7% fewer primary care visits (RR 0.93, 95% CI 0.91, 0.95), 15% more emergency department visits (RR 1.15, 95% CI 1.09, 1.22), and 18% more avoidable hospitalizations (RR 1.18, 95% CI 1.01, 1.37). After adjustment for individual- (race/ethnicity, sex, number of chronic conditions, insurance status) and neighborhood-level (racial composition and proportion of housing units with no vehicle), spatial accessibility was not significantly associated with rate of health care utilization., Conclusions: Individual-level predisposing factors, such as age, race, and need, attenuate the association between accessibility to primary care and use of primary care, emergency department visits, and avoidable hospitalization. Given the possibility of modifying access to primary care unlike immutable individual factors, a focus on spatial accessibility to primary care may promote appropriate health care utilization., (Copyright © 2020 Academic Pediatric Association.

Background: Pediatric primary care visits are a foundational element in the health maintenance of children. Differential access may be a driver of racial inequities in health. We hypothesized that pediatric primary care accessibility would be lowest in neighborhoods with higher proportion of non-Hispanic Black residents., Methods: Annual ratios (2008-2016) of providers to pediatric population were calculated by census tract in Philadelphia, Pennsylvania. Marginal logistic regression was used to estimate the independent association between neighborhood racial composition and access to pediatric primary care controlling for confounders., Results: In general, low access to care was associated with greater neighborhood disadvantage (e.g., SES, % poverty, % public insurance). After controlling for neighborhood indicators of disadvantage, risk of being in the lowest quintile of access significantly increased as the percent of non-Hispanic Black residents increased., Conclusion: A new measure of pediatric primary care accessibility demonstrates a persistent disparity in primary care access for predominantly non-Hispanic Black neighborhoods.

Background: In children, community-acquired pneumonia is a frequent cause of emergency department (ED) presentation and hospital admission. Quality primary care may prevent some of these hospital visits., Aims: The aim of this study was to identify primary care factors associated with ED presentation and hospital admission of preschool-aged children with community-acquired pneumonia., Methods: A case-control study was conducted by enrolling three groups: children presenting to the ED with pneumonia and admitted (n = 326), or discharged home (n = 179), and well-neighbourhood controls (n = 351). Interviews with parents and primary care staff were conducted and health record review was performed. The association of primary care factors with ED presentation and hospital admission, controlling for available confounding factors, was determined using logistic regression., Results: Children were more likely to present to the ED with pneumonia if they did not have a usual general practitioner (GP) (odds ratio (OR) = 2.50, 95% confidence interval (CI) = 1.67-3.70), their GP worked ⩽ 20 h/week (OR = 1.86, 95% CI = 1.10-3.13) or their GP practice lacked an immunisation recall system (OR = 5.44, 95% CI = 2.26-13.09). Lower parent ratings for continuity (OR=1.63, 95% CI = 1.01-2.62), communication (OR = 2.01, 95% CI = 1.29-3.14) and overall satisfaction (OR = 2.16, 95% CI = 1.34-3.47) increased the likelihood of ED presentation. Children were more likely to be admitted when antibiotics were prescribed in primary care (OR = 2.50, 95% CI = 1.43-4.55). Hospital admission was less likely if children did not have a usual GP (OR = 0.22, 95% CI = 0.11-0.40) or self-referred to the ED (OR = 0.48, 95% CI = 0.26-0.89)., Conclusions: Accessible and continuous primary care is associated with a decreased likelihood of preschool-aged children with pneumonia presenting to the ED and an increased likelihood of hospital admission, implying more appropriate referral. Lower parental satisfaction is associated with an increased likelihood of ED presentation.

Objective: To assess the effects of electronic health record-based clinical decision support (CDS) and physician performance feedback on adherence to guidelines for acute otitis media (AOM) and otitis media with effusion (OME)., Methods: We conducted a factorial-design cluster randomized trial with primary care practices (n = 24) as the unit of randomization and visits as the unit of analysis. Between December 2007 and September 2010, data were collected from 139,305 otitis media visits made by 55,779 children aged 2 months to 12 years. When activated, the CDS system provided guideline-based recommendations individualized to the patient's history and presentation. Monthly physician feedback reported adherence to guideline-based care, changes over time, and comparisons to others in the practice and network., Results: Comprehensive care (all recommended guidelines were adhered to) was accomplished for 15% of AOM and 5% of OME visits during the baseline period. The increase from baseline to intervention periods in adherence to guidelines was larger for CDS compared with non-CDS visits for comprehensive care, pain treatment, adequate diagnostic evaluation for OME, and amoxicillin as first-line therapy for AOM. Although performance feedback was associated with improved antibiotic prescribing for AOM and pain treatment, the joint effects of CDS and feedback on guideline adherence were not additive. There was marked variation in use of the CDS system, ranging from 5% to 45% visits across practices., Conclusions: Clinical decision support and performance feedback are both effective strategies for improving adherence to otitis media guidelines. However, combining the 2 interventions is no better than either delivered alone.

Objective: To examine the effects of an intervention comprising (1) a practice-based care coordination program, (2) augmented by pay for performance (P4P) for meeting quality targets, and (3) complemented by a third-party disease management on quality of care and resource use for older adults with diabetes., Data Sources/study Setting: Claims files of a managed care organization (MCO) for 20,943 adults aged 65 and older with diabetes receiving care in Alabama, Tennessee, or Texas, from January 2004 to March 2007., Study Design: A quasi-experimental, longitudinal study in which pre- and postdata from 1,587 patients in nine intervention primary care practices were evaluated against 19,356 patients in MCO comparison practices (>900). Five incentivized quality measures, two nonincentivized measures, and two resource-use measures were investigated. We examined trends and changes in trends from baseline to follow-up, contrasting intervention and comparison group member results., Principal Findings: Quality of care generally improved for both groups during the study period. Only slight differences were seen between the intervention and comparison group trends and changes in trends over time., Conclusions: This study did not generate evidence supporting a beneficial effect of an on-site care coordination intervention augmented by P4P and complemented by third-party disease management on diabetes quality or resource use., (© Health Research and Educational Trust.)

Purpose: Increasing use of specialist services in the United States is leading to a perception of a specialist shortage. Little is known, however, about the nature of care provided by this secondary level of services. The aim of this study was to examine the content of care provided by specialists in community settings, including visits for which the patient had been referred by another physician., Methods: Nationally representative visit data were obtained from the National Ambulatory Medical Care Survey (NAMCS) for the years 2002 through 2004. To describe the nature of care, we developed a taxonomy of office-based visit types and constructed logistic regression models allowing for adjusted comparisons of specialty types., Results: Overall, 46.3% of visits were for routine follow-up and preventive care of patients already known to the specialist. Referrals accounted for only 30.4% of all visits. Specialists were more likely to report sharing care with other physicians for referred, compared with not referred, patients (odds ratio [OR] = 2.99; 95% confidence interval [CI], 2.52-3.55). Overall, 73.6% of all visits resulted in a return appointment with the same physician, in more than one-half of all cases as a result of a routine or preventive care visit., Conclusions: Ambulatory office-based activity of specialists includes a large share of routine and preventive care for patients already known, not referred, to the physician. It is likely that many of these services could be managed in primary care settings, lessening demand for specialists and improving coordination of care.

Purpose: This study describes referral completion from the perspectives of patients and primary care physicians and identifies predictors of adherence to the referral recommendation., Methods: We observed a cohort of 776 referred patients from the offices of 133 physicians in 81 practices and 30 states. Referring physicians and patients completed self-administered questionnaires at the time of the referral decision and 3 months later., Results: Physicians reported that 79.2% of patients referred had a specialist visit, and 83.0% of patients indicated they completed the referral. The most common reasons for not completing the referral were "lack of time" and patient belief that the "health problem had resolved." The kappa statistic for patient-physician agreement on referral completion was 0.34, indicating only fair concordance. Patients in Medicaid plans were less likely than others to complete the referral, and more likely to experience a health plan denial. A longer duration of the patient relationship with the primary care physician and physician/staff scheduling of the specialty appointment were both positive predictors of referral completion., Conclusions: About 8 in 10 patients referred from primary care complete a specialty referral within 3 months. Findings from this study suggest that referral completion rates may be increased by assisting patients with scheduling their specialty appointments and promoting continuity of care.

Objectives: To compare mix of patients, scope of practice, and duration of visit in primary care physicians in Australia, New Zealand, and the United States., Design: Comparison of three comparable cross sectional surveys performed in 2001-2. Physicians completed a questionnaire on patients' demographics, diagnoses, and duration of visit., Setting: Primary care practice., Participants: 79,790 office visits in Australia, 10,064 in New Zealand, and 25,838 in the US., Main Outcome Measures: Diagnostic codes were mapped to the Johns Hopkins expanded diagnostic clusters. Scope of practice was defined as the number of expanded diagnostic clusters accounting for 75% of all managed problems related to morbidity. Exposure to primary care was calculated from duration of visits recorded by the physician, and reports on rates of visits to primary care for each country., Results: In each country, primary care physicians managed an average of 1.4 morbidity related problems per visit. In the US, 46 expanded diagnostic clusters accounted for 75% of problems managed compared with 52 in Australia, and 57 in New Zealand. Correlations in the frequencies of managed health problems between countries were high (0.87-0.97 for pairwise comparisons). Though primary care visits were longer in the US than in New Zealand and Australia, the per capita annual exposure to primary care physicians in the US (29.7 minutes) was about half of that in New Zealand (55.5 minutes) and about a third of that in Australia (83.4 minutes) because of higher rates of visits to primary care in these countries., Conclusions: Despite differences in the supply and financing of primary care across countries, many aspects of the clinical practice of primary care physicians are remarkably similar in Australia, New Zealand, and the US.

Objective: To identify correlates of behavioral management strategies and to test whether children with more severe behavioral problems have care transferred to mental health specialists., Methods: Secondary analysis of the Child Behavior Study. Children aged 4 to 15 years were identified with new behavioral problems at nonurgent visits to primary care clinicians. Treatment strategies were categorized into mutually exclusive groups: primary care (psychotropic prescription and/or office-based counseling), mental health care (referral for or ongoing specialist mental health care), joint care (primary care and mental health care), or observation. Child-, family-, clinician-, and practice-level characteristics were assessed for association with management strategies by use of multivariate methods., Results: A total of 1377 children from 201 practices in 44 states and Puerto Rico were newly identified with behavioral problems. Behavioral/conduct (41 per cent), attentional/hyperactivity (37 per cent), adjustment (32 per cent), and emotional (22 per cent) problems were most commonly identified. Children with comorbid behavioral problems were more likely to be managed with joint care than other treatment strategies. In addition, clinicians who were male or who had greater mental health orientation were more likely to provide joint care than mental health care only., Conclusions: Clinicians were more likely to manage new behavioral problems jointly with mental health providers than use other strategies if children had coexisting mental health problems or if providers had stronger beliefs about psychosocial aspects of care. These results do not support the hypothesis that children with more severe behavioral problems are transferred to specialists but suggest that primary care and mental health care clinicians may benefit from collaborating on treatment plans.

Purpose: To examine the effects of patient, physician, and health care system characteristics on primary care physicians' (PCPs') specialty referral decision making., Methods: Physicians (n=142) and their practices (n=83) located in 30 states completed background questionnaires and collected survey data for all patient visits (n=34,069) made during 15 consecutive workdays. The authors modeled the occurrence of any specialty referral, which occurred during 5.2% of visits, as a function of patient, physician, and health care system structural characteristics. A subanalysis was done to examine determinants of referrals made for discretionary indications (17% of referrals), operationalized as problems commonly managed by PCPs, high level of diagnostic and therapeutic certainty, low urgency for specialist involvement, and cognitive assistance only requested from the specialist., Results: Patient characteristics had the largest effects in the any-referral model. Other variables associated with an increased risk of referral included PCPs with less tolerance of uncertainty, larger practice size, health plans with gate-keeping arrangements, and practices with high levels of managed care. The risk of a referral being made for discretionary reasons was increased by capitated primary care payment, internal medicine specialty of the PCP, high concentration of specialists in the community, and higher levels of managed care in the practice., Conclusions: PCPs' referral decisions are influenced by a complex mix of patient, physician, and health care system structural characteristics. Factors associated with more discretionary referrals may lower PCPs' thresholds for referring problems that could have been managed in their entirety within primary care settings.

This study compared community-governed nonprofit and for-profit primary care practices in New Zealand to test two hypotheses: (1) nonprofits reduce financial and cultural barriers to access; and (2) nonprofits do not differ from for-profits in equipment, services, service planning, and quality management. Data were obtained from a nationally representative cross-sectional survey of GPs. Practices were categorized by ownership status: private community-governed nonprofit or private for-profit. Community-governed nonprofits charged lower patient fees per visit and employed more Maori and Pacific Island staff, thus reducing financial and cultural barriers to access compared with for-profits. Nonprofits provided a different range of services and were less likely to have specific items of equipment; they were more likely to have written policies on quality management, complaints, and critical events, and to carry out locality service planning and community needs assessments. The findings support the shift to nonprofit community governance occurring in New Zealand and elsewhere.

Objective: To examine reasons for the adoption of liquid-based cervical cancer screening tests., Data Sources/study Setting: A mailed survey of 250 family physicians and 250 gynecologists in Maryland in 2000. Additional data were obtained from the AMA Master File of Physicians., Study Design: Key outcome variables in this cross-sectional survey were early adoption of a liquid-based test by the end of 1997 and overall adoption by the time of the survey. Adoption was viewed in terms of a supply and demand theoretical framework with marketing influencing physician and patient demand as well as supply by insurance companies and laboratories., Data Collection: Random samples of family physicians and gynecologists were selected from the AMA Master File of Physicians. The overall response rate was 61.9 percent., Principal Findings: By 2000, 96 percent of gynecologists and 75 percent of family physicians in Maryland were using liquid-based cervical cancer screening tests, most commonly the ThinPrep Pap Test. Gynecologists were more likely than family physicians to have been early adopters (34 percent versus 5 percent, p<.01). Part of this variation in adoption was due to aggressive marketing to gynecologists, who were more likely than family physicians to receive information in the mail from the test manufacturer (89 percent versus 56 percent, p<.01) and to have been informed by the manufacturer that a patient had inquired about physicians' use of the test (22 percent versus 8 percent, p<.01)., Conclusions: The rapid diffusion of liquid-based cervical cancer screening tests occurred despite general agreement that the Pap smear has been one of the most successful cancer prevention interventions ever. Commercial marketing campaigns appear to contribute to the more rapid rate of diffusion of technology among specialists compared with generalists.

Objectives: We examined the association between attributes of primary care providers and care for depression, from a patients' perspective, among a sample of predominantly low-income African American women., Methods: Computer-assisted telephone interviews were conducted among a population-based sample of 1202 women residing in Washington, DC., Results: Respondents whose primary care physicians provided more comprehensive medical services were more likely to be asked about and treated for depressive symptoms than women whose providers were less medically comprehensive. Women who rated their providers as having more respect for them also were more likely to be asked about and treated for depression., Conclusions: More comprehensive primary care delivery and a physician-patient relationship focused on mutual respect are associated with greater rates of physician inquiry about and treatment for depression among vulnerable women.

Background: Although comorbidity is very common in the population, little is known about the types of health service that are used by people with comorbid conditions., Methods: Data from claims on the nonelderly were classified by diagnosis and extent of comorbidity, using a case-mix measure known as the Johns Hopkins Adjusted Clinical Groups, to study variation in extent of comorbidity and resource utilization. Visits of patients (adults and children) with 11 conditions were classified as to whether they were to primary care physicians or to other specialists, and whether they involved the chosen condition or other conditions., Results: Comorbidity varied within each diagnosis; resource use depended on the degree of comorbidity rather than the diagnosis. When stratified by degree of comorbidity, the number of visits for comorbid conditions exceeded the number of visits for the index condition in almost all comorbidity groups and for visits to both primary care physicians and to specialists. The number of visits to primary care physicians for both the index condition and for comorbid conditions almost invariably exceeded the number of visits to specialists. These patterns differed only for uncommon conditions in which specialists played a greater role in the care of the condition, but not for comorbid conditions., Conclusions: In view of the high degree of comorbidity, even in a nonelderly population, single-disease management does not appear promising as a strategy to care for patients. In contrast, the burden is on primary care physicians to provide the majority of care, not only for the target condition but for other conditions. Thus, management in the context of ongoing primary care and oriented more toward patients' overall health care needs appears to be a more promising strategy than care oriented to individual diseases. New paradigms of care that acknowledge actual patterns of comorbidities as well as the need for close coordination between generalists and specialists require support.

Objectives: We examined whether patients' perceptions of their relationships with primary care practitioners (PCPs) vary by vulnerability status and assessed the extent to which gatekeeping arrangements and primary care performance moderate potential disparities., Methods: We used the nationally representative 1996-1997 Community Tracking Study Household Survey as our data source., Results: Whites reported better patient-practitioner relationships than minorities. Requirements that patients select a PCP and obtain referral authorization neither reduced nor exacerbated racial disparities in the patient-practitioner relationship. On the other hand, access to and continuity with a PCP substantively reduced disparities, especially for the most vulnerable group., Conclusions: Enhancing primary care performance may reduce some of the barriers to care experienced by vulnerable populations, thereby improving patients' relationships with their PCPs.

Socioeconomic disparities in women's primary care experiences have been described previously. To better understand whether these disparities reflect personal preferences for primary care, rather than insurance or other access barriers, we conducted a telephone survey of a community-based sample of 1,205 women in Washington, DC. The study found that women of lower socioeconomic status had poorer primary care experiences compared with higher income counterparts, despite similarly high preferences for primary care. The poorer primary care experiences of lower socioeconomic status women were attenuated by better access to primary care. Differences in primary care attainment are not solely a matter of personal preferences; rather, they appear to be more strongly related to barriers to obtaining care.

Objectives: This study examines how specific attributes of managed health plans influence patients' relationships with their primary care practitioners (PCPs) and determines whether these effects are mediated by access to, continuity with, or perceived choice of PCPs., Design, Setting, Patients: The data source was the nationally representative 1996/97 Community Tracking Study Household Survey (cumulative response rate 65%). The study population (N = 19,415) was composed of 18- to 64-year-old adults whose most recent visit in the past 12 months was made to their primary care delivery site., Main Outcome Measure: Patients' ratings of their interpersonal relationships with their PCPs as measured by a 7-item scale., Results: Gatekeeping arrangements that require patients to select a primary care physician or obtain authorization for specialty referrals were associated with lower ratings of the patient-PCP relationship. Health plan use of a provider network had no effect on the patient-PCP scale score. Although there were no significant differences across any insurance payer categories, uninsured adults rated their relationships with PCPs as significantly poorer than did their insured counterparts. Shorter office waits, having a specific clinician at the primary care site, better perceived choice of PCPs, and a longer duration of relationship with the primary care practitioner were associated with higher ratings of the patient-PCP relationship. Perceived choice of primary care practitioners, but not access to or continuity with PCPs, attenuated some of the negative effects of gatekeeping arrangements on patients' relationships with their primary care practitioners., Conclusions: Managed health plans that loosen restrictions on provider choice, relax gatekeeping arrangements, or promote access to and continuity with PCPs, are likely to experience higher patient satisfaction with their primary care practitioner relationships. Lack of health insurance impedes the development of patients' relationships with their primary care practitioners.

Objective: To examine family physicians' referral decisions, which we conceptualized as having 2 phases: whether to refer followed by to whom to refer., Study Design: Prospective cohort study., Population: All visits (N = 34,519) and new referrals (N = 2534) occurring during 15 consecutive business days in the offices of 141 family physicians in 87 practices located in 31 states., Outcomes Measured: Rates of referral, reasons for referral, practitioners referred to, health problems prompting referral, and reasons for selecting particular specialists., Results: Approximately 1 in 20 (5.1%) office visits led to referral. Although 68% of referrals were made by physicians during office visits, 18% were made by physicians during telephone conversations with patients, 11% by office staff with input from the physician, and 3% by staff without physician input. Physicians endorsed a mean of 1.8 reasons for making a referral. They sought specialists' advice on either diagnosis or treatment for 52.1% of referrals and asked the specialist to direct medical management for 25.9% and surgical management for 37.8%. Patient request was one reason for 13.6% of referrals. Fifty conditions accounted for 76% of all referrals. Surgical specialists were sent the largest share of referrals (45.4%), followed by medical specialists (31.0%), nonphysician clinicians (12.1%), obstetrician-gynecologists (4.6%), mental health professionals (4.2%), other practitioners (2.0%), and generalists (0.8%). Physicians recommended a specific practitioner to the patient for most (86.2%) referrals. Personal knowledge of the specialist was the most important reason for selecting a specific specialist., Conclusions: Referrals are commonly made during encounters other than office visits, such as telephone conversations or staff-patient interactions, in primary care practice. Training in the referral process should ensure that family physicians obtain the skills necessary to expand their scope of practice, when appropriate; determine when and why a patient should be referred; and identify the type of practitioner to whom the patient should be sent.

Objective: To assess whether primary care performance of low-income women's primary care delivery sites is associated with the strength of their relationships with their physicians., Design: Random-digit-dial and targeted household telephone survey of a population-based sample., Setting: Washington, D.C. census tracts with > or =30% of households below 200% of federal poverty threshold., Participants: Women over age 40 (N=1,205), 82% of whom were African American., Measurements and Main Results: The response rate was 85%. Primary care performance was assessed using women's ratings of their systems' accessibility (organizational, geographic, and financial), continuity, comprehensiveness, and coordination. Respondents' ratings of trust in their physicians, communication with their physicians, and compassion shown by their physicians were used to operationalize the patient-physician relationship. Controlling for population and insurance characteristics, 4 primary care features were positively associated with women's trust in and communication with their physicians: continuity with a single clinician, organizational accessibility of the practice, comprehensive care, and coordination of specialty care services. Better organizational access, but not geographic or financial access, was associated with greater levels of trust, compassion, and communication (odds ratios [ORs], 3.2, 7.4, and 6.9, respectively; P < or =.01). Women who rated highest their doctor's ability to take care of all of their health care needs (highest level of comprehensiveness) had 11 times the odds of trusting their physician (P < or =.01) and 6 times the odds of finding their physicians compassionate and communicative (P < or =.01), compared to those with the lowest level of comprehensiveness., Conclusions: Primary care delivery sites organized to be more accessible, to link patients with the same clinician for their visits, to provide for all of a woman's health care needs, and to coordinate specialty care services are associated with stronger relationships between low-income women and their physicians. Primary care systems that fail to emphasize these features of primary care may jeopardize the clinician-patient relationship and indirectly the quality of care and health outcomes.

Our objectives were to 1) quantify the frequency of wheezing episodes and asthma diagnosis in young children in a large pediatric primary care network and 2) assess the variability in practice-level asthma diagnosis, accounting for common asthma risk factors and comorbidities. We hypothesized that significant variability in practice-level asthma diagnosis rates would remain after adjusting for associated predictors. We generated a retrospective longitudinal birth cohort of children who visited 1 of 31 pediatric primary care practices within the first 6 months of life from 1/2005 to 12/2016. Children were observed for up to 8 years or until the end of the observation window. We used multivariable discrete time survival models to evaluate predictors of asthma diagnosis by 3-month age intervals. We compared unadjusted and adjusted proportions of children diagnosed with asthma by practice. Of the 161,502 children in the cohort, 34,578 children (21%) received at least 1 asthma diagnosis. In multivariable modeling, male gender, minority race/ethnicity, gestational age <34 weeks, allergic rhinitis, food allergy, and prior wheezing episodes were associated with asthma diagnosis. After adjusting for variation in these predictors across practices, the cumulative incidence of asthma diagnosis by practice by age 6 years ranged from 11% to 47% (interquartile range: 24%–29%). Across pediatric primary care practices, adjusted incidence of asthma diagnosis by age 6 years ranged widely, though variation gauged by the interquartile range was more modest. Potential sources of practice-level variation, such as differing diagnosis thresholds and labeling of different wheezing phenotypes as "asthma," should be further investigated.

Social, psychological, and behavioral factors are recognized as key contributors to health, but they are rarely measured in a systematic way in health care settings. Electronic health records (EHRs) can be used in these settings to routinely collect a standardized set of social, psychological, and behavioral determinants of health. The expanded use of EHRs provides opportunities to improve individual and population health, and offers new ways for the psychological community to engage in health promotion and disease prevention efforts. This article addresses 3 issues. First, it discusses what led to current efforts to include measures of psychosocial and behavioral determinants of health in EHRs. Second, it presents recommendations of an Institute of Medicine committee regarding inclusion in EHRS of a panel of measures that meet a priori criteria. Third, it identifies new opportunities and challenges these recommendations present for psychologists in practice and research. [ABSTRACT FROM AUTHOR]

Context: The US primary care safety net is composed of a loose network of community health centers, hospital outpatient departments, and physicians' offices. National data on how the mix of patients and services differ across sites are needed.Objective: To develop and contrast national profiles of patient and service mix for primary care.Design, Setting, and Patients: Comparative analyses of 3 national surveys of primary care visits occurring in 1994: for data on physician's office visits, the National Ambulatory Medical Care Survey (NAMCS); for hospital outpatient department data, the National Hospital Ambulatory Medical Care Survey (NHAMCS); and for data on community health centers, the Bureau of Primary Health Care's 1994 Survey of Visits to Community Health Centers. A time trend analysis also was conducted using the 1998 NAMCS and NHAMCS.Main Outcome Measures: National estimates of primary care visit rates, types of patient presentation, patient case-mix, disposition of patients, and management interventions in 1994, and compared with 1998 data.Results: The US population made 1.3 primary care visits per person in 1994, which accounted for 43.5% of all ambulatory visits to physicians' offices, community health centers, and hospital outpatient departments. Primary care visits per person were 20% lower for Hispanics and 33% lower for black, non-Hispanic persons compared with white, non-Hispanic persons. Visits to community health centers were more likely to be made by ethnic minorities, patients with Medicaid or no insurance, and rural dwellers than visits made to the other delivery sites. Visits at hospital outpatient departments were made by sicker populations and were characterized by less continuity than the other delivery sites. Controlling for patient mix, visits made to hospital outpatient departments were more commonly associated with imaging studies, minor surgery, and specialty referrals than those made to physicians' offices. In 1998, the US population made an estimated 3. 4 visits per person, 45.6% of which were primary care visits. National estimates of primary care visit rates and patient mix and practice pattern comparisons between hospital outpatient departments and physicians' offices were similar in 1998 and 1994.Conclusions: Expanding community health centers will likely improve access to primary care for vulnerable US populations. However, enhancing access to of physicians' offices is also needed to bolster the safety net. The greater service intensity and poorer continuity for primary care visits in hospital outpatient departments that we observed raises concern about the suitability of these clinics as primary care delivery sites.

BACKGROUND • Because of their challenging social and economic environments, low-income women may find particular features of primary care uniquely important. For this qualitative study we explored which features are priorities to women from low-income settings and whether those priorities fit into an established primary care framework. METHODS • We performed a qualitative analysis of 4 focus groups of women aged 40 to 65 years from 4 community health clinics in Washington, DC. Prompted by semistructured open-ended questions, the focus groups discussed their experiences with ambulatory care and the attributes of primary care that they found important. The focus groups were audiotaped, and the tapes were transcribed verbatim and coded independently by 3 readers. RESULTS • The comments were independently organized into 5 content areas of primary care service delivery plus the construct of patient-provider relationship in the following order of frequency: accessibility (37.4%), the physician-patient relationship (37.4%)), comprehensive scope of services (11.5%) coordination between providers (6.8%), continuity with a single clinician (3.7%), and accountability (3.2%). Commonly reported specific priorities included a sense of concern and respect from the clinicians and staff toward the patient, a physician who was willing to talk and spend time with them (attributes of the physician-patient relationship), weekend or evening hours, waiting times (attributes of organizational accessibility), location in the inner city and on public transport routes (an attribute of geographic accessibility), availability of coordinated social and clinical services on-site: and availability of mental health services on-site (attributes of comprehensiveness and of coordination). CONCLUSIONS • All attributes of care that were priorities for low-income women fit into 1 of 6 content areas. Specific features within the content areas of accessibility, physician-patient relationship and comprehensiveness were particularly important for these women. [ABSTRACT FROM AUTHOR]

Background. A study was undertaken to examine the relationship between first-contact care, an essential feature of primary care, and expenditures for frequent ambulatory episodes of care in a nationally representative sample. Methods. A nonconcurrent cohort study was conducted using data from the 1987 National Medical Expenditure Survey. Ambulatory claims data of respondents with an identified primary care source were used to develop 20,282 episodes of care for 24 preventive and acute illness conditions. The study examined the relationship of first-contact care, defined as the use of an identified primary care source for the first visit in an episode, and ambulatory episode-of-care expenditures. Results. Episodes that began with visits to an individual's primary care clinician, as opposed to other sources of care, were associated with reductions in expenditures of 53% overall ($63 vs $134, P<.001), 62% for acute illnesses ($62 vs $164, P<.001), and 20% for preventive care ($64 vs $80, P<.001). For 23 of the 24 health problems studied, first-contact care was associated with reductions in expenditures. Multivariate regression analyses that controlled for sociodemographic characteristics, health status, case-mix, length of the episode, and number of visits to the emergency room did not substantively alter these results. Conclusions. First-contact care was associated with reductions in ambulatory episode-of-care expenditures of over 50% in a nationally representative sample. These findings suggest that systems of care that promote the first-contact aspect of primary care may reduce ambulatory expenditures. [ABSTRACT FROM AUTHOR]

Introduction: Clinicians require tools to rapidly identify individuals with significant childhood adversity as part of routine primary care. The goal of this study was to shorten the 11-item Behavioral Risk Factor Surveillance System Adverse Childhood Experiences (ACEs) measure and evaluate the feasibility and validity of this shortened measure as a screener to identify adults who have experienced significant childhood adversity.Methods: Statistical analysis was conducted in 2015. ACE item responses obtained from 2011-2012 Behavioral Risk Factor Surveillance System data were combined to form a sample of 71,413 adults aged ≥18 years. The 11-item Behavioral Risk Factor Surveillance System ACE measure was subsequently reduced to a two-item screener by maintaining the two dimensions of abuse and household stressors and selecting the most prevalent item within each dimension.Results: The screener included household alcohol and childhood emotional abuse items. Overall, 42% of respondents and at least 75% of the individuals with four or more ACEs endorsed one or both of these experiences. Using the 11-item ACE measure as the standard, a cut off of one or more ACEs yielded a sensitivity of 99%, but specificity was low (66%). Specificity improved to 94% when using a cut off of two ACEs, but sensitivity diminished (70%). There was no substantive difference between the 11-and two-item ACE measures in their strength of association with an array of health outcomes.Conclusions: A two-item ACE screener appropriate for rapid identification of adults who have experienced significant childhood adversity was developed.

BACKGROUND. The purpose of this study was to determine the extent to which consumer and provider reports of primary care differ according to particular characteristics of the primary care setting. METHODS. A random sample of consumers was surveyed by telephone in a defined geographic area of Washington, DC, to determine their experiences with care provided to a randomly chosen child. The primary care provider of each respondent was sent a parallel survey. Scores were obtained for each of two subdomains in the four cardinal primary care domains (first contact, longitudinality, comprehensiveness, and coordination) and for three related domains (family centeredness, community orientation, and cultural competence). Differences between settings that did or did not impose limitations on autonomy for referrals and between fee-for-service and capitated settings were ascertained. RESULTS. Both consumers and their providers in settings characterized by high degrees of limitation on physician autonomy or by capitation reported better first-contact accessibility and a greater range of services available than did consumers in settings with low degrees of limitation, or by fee-for-service reimbursements to physicians. Consumers but not providers reported better family centeredness in these settings. Most other differences favored these settings as well, but these were not consistently statistically significant for both providers and consumers in both types of settings. CONCLUSIONS. The quality of primary care services in different settings can be ascertained by using an instrument with demonstrated reliability and convergent validity. Although certain types of settings, in the particular geographic area studied, appear to perform better in several key aspects of primary care, replication of the study in other areas would be useful before judging the performance of the newer types of settings to be superior to more conventional care for general populations.
