Pediatric length of stay guidelines and routine practice: the case of Milliman and Robertson.

BACKGROUND: Guidelines for inpatient length of stay (LOS) have been developed by Milliman and Robertson (M&R) and are widely applied by health plans. This study was designed to compare LOS for several pediatric conditions with the M&R LOS criteria using recent data and to determine if concordance of actual practice with M&R LOS criteria varied between children and adults. DESIGN: Administrative data from Pennsylvania hospitals from 1996 through 1998 were used to examine LOS for hospital discharges for 12 selected diagnoses for which M&R published guidelines for children and adults. PATIENTS: Discharge data for all patients discharged from public and private hospitals in Pennsylvania for which 1 of 12 selected diagnoses were examined. MAIN OUTCOME MEASURE: Length of stay. RESULTS: In Pennsylvania hospitals from 1996 through 1998, pediatric LOS was divergent for all conditions examined, although not to the extent found in a previous study examining data from New York State. Of note, median LOS for some conditions was shorter than M&R LOS criteria. The percentage of pediatric hospital discharges that exceeded the M&R LOS criteria ranged from 25% for pneumonia to 84% for meningitis. Adult hospital discharges exceeded M&R LOS criteria to a greater extent than did pediatric discharges for all conditions except for sickle cell crisis and meningitis. CONCLUSIONS: The M&R LOS criteria were divergent from routine practice for both children and adults. Greater divergence of adult discharges illustrates the need to consider comorbid conditions when implementing these guidelines. Thus, patient care may suffer if guidelines are implemented in an uninformed way. These findings emphasize the importance of using the best possible science when producing guidelines such as these.

Primary care patients' personal illness models for depression: a preliminary investigation.

BACKGROUND: Despite the fact that more than half of depressed persons are treated for this disorder by primary care physicians, depression is often under-recognized or treated inadequately. There is continued emphasis on effective treatment of depression in primary care patients, but little attention has been paid to the role of the depressed person's illness cognitions in coping with this disorder. Given the often recurring and chronic nature of depression, the individual's self-management strategies may be critical to effective treatment, recovery and remaining well. OBJECTIVES: The purpose of this pilot study was to determine whether primary care patients' personal illness cognitions for depression are associated with depression coping strategies and treatment-related behaviour. METHODS: Forty-one primary care patients with depressive symptoms or disorder completed interviews and questionnaires assessing illness cognitions for depression, depression coping strategies and other treatment-related behaviour. Descriptive statistics are used to present patients' illness cognitions for depression. t-tests and correlational analyses were completed to assess the relationship between illness cognitions, depression coping strategies and treatment-related behaviour. RESULTS: Preliminary data describing illness cognitions for depression are presented. Participants' illness cognitions for depression were significantly associated with current and past treatment-seeking behaviour, medication adherence and coping strategies. CONCLUSIONS: Although preliminary, these findings indicate that patients' understanding of depression and its consequences are associated with how they manage this illness. Future research is needed to examine the mediating and moderating effects of illness cognitions for depression on medication adherence and other self-management behaviours of depressed primary care patients. Knowledge about primary care patients' personal illness models will aid in the development of adherence interventions, self-management training and support services appropriate to patients' needs in the primary care setting.

Does the family APGAR effectively measure family functioning?

BACKGROUND: The Family APGAR has been widely used to study the relationship of family function and health problems in family practice offices. METHODS: Data were collected from 401 pediatricians and family physicians from the Pediatric Research in Office Settings network and the Ambulatory Sentinel Practice Network. The physicians enrolled 22,059 consecutive office visits by children aged 4 to 15 years. Parents completed a survey that included the Family APGAR and the Pediatric Symptom Checklist. Clinicians completed a survey that described child psychosocial problems, treatments initiated or continued, and specialty care referrals. RESULTS: Family dysfunction on the index visit often differed from dysfunction at follow-up (kappa=0.24). Only 31% of the families with positive Family APGAR scores at baseline were positive at follow-up, and only 43% of those with positive scores at follow-up had a positive score at the initial visit. There were many disagreements between the Family APGAR and the clinician. The Family APGAR was negative for 73% of clinician-identified dysfunctional families, and clinicians did not identify dysfunction for 83% of Family APGAR-identified dysfunctions (kappa=0.06). CONCLUSIONS: Our data do not support the use of the Family APGAR as a measure of family dysfunction in the primary care setting. Future research should clarify what it does measure.

Mental health care utilization and expenditures by children in foster care.

OBJECTIVE: To determine the percentage of children with mental health diagnoses and utilization and expenditures of mental health services among children in foster care compared with other children receiving Medicaid, including those with disabilities. DESIGN: Analysis of Medicaid claim and eligibility records in southwestern Pennsylvania for fiscal year 1995. POPULATION: A total of 39,500 children between ages 5 and 17 years continuously eligible for Medicaid in southwestern Pennsylvania were included in the analysis. MAIN OUTCOME MEASURES: Percentage of children with mental health diagnoses and mental and general health care utilization and expenditures classified by participation in foster care and Medicaid eligibility. RESULTS: Children in foster care were 3 to 10 times more likely to receive a mental health diagnosis, had 6.5 times more mental health claims, were 7.5 times more likely to be hospitalized for a mental health condition, and had mental health expenditures that were 11.5 times greater ($2082 vs $181) than children in the Aid to Families With Dependent Children (AFDC) program. Overall, utilization rates, expenditures, and prevalence of psychiatric conditions for children in foster care were comparable with those of children with disabilities. CONCLUSIONS: Children in foster care are significantly more likely to suffer from mental health conditions and use more mental health and general health services than AFDC children. Service use and expenditures are comparable with those of disabled children, suggesting that reimbursement rates and care management for children in foster care need to be reexamined.

Effect of different recruitment sources on the composition of a bipolar disorder case registry.

BACKGROUND: Conducting research on low-prevalence conditions presents an ongoing challenge for clinical and services researchers. Recruitment through health professionals versus other forms of self-referral may affect study group composition. METHODS: We compared members of a voluntary case registry for bipolar disorder who were recruited through a variety of sources including health professionals, support groups, an Internet website, and mailings, brochures, and other general public relations activities. We also compared the cost of recruitment methods. We hypothesized that self-referred registry members would be of higher socioeconomic status and less likely to be in treatment compared to members recruited through health professionals. RESULTS: Registrants referred through the Internet and patient support groups were better educated and more likely to be married than other registrants. However, Internet registrants were younger, had fewer lifetime hospitalizations and were more likely to be working. Nearly all registrants were in treatment with a psychiatrist. Local registrants were predominantly recruited through health professionals and public presentations. Registrants outside of the local region most often learned about the registry from patient support groups and the Internet. Local registrants were less likely to be using non-lithium mood stabilizers. Recruitment through public relations efforts was the most expensive method of recruitment, and the Internet website was the cheapest. CONCLUSIONS: Diverse recruitment methods can expand the population available for clinical trials. For services research, the Internet and patient support groups are less expensive ways to identify persons served in diverse settings and health plans, but these recruitment methods yield a sample that is better educated than the remainder of the population. It remains a difficult task to identify minorities and persons not in treatment.

Treatment services for children with ADHD: a national perspective.

OBJECTIVE: To summarize knowledge on treatment services for children and adolescents with attention-deficit hyperactivity disorder (ADHD), trends in services from 1989 to 1996, types of services provided, service mix, and barriers to care. METHOD: A review of the literature and analyses from 2 national surveys of physician practices are presented. RESULTS: Major shifts have occurred in stimulant prescriptions since 1989, with prescriptions now comprising three fourths of all visits to physicians by children with ADHD. Between 1989 and 1996, related services, such as health counseling, for children with ADHD increased 10-fold, and diagnostic services increased 3-fold. Provision of psychotherapy, however, decreased from 40% of pediatric visits to only 25% in the same time frame. Follow-up care also decreased from more than 90% of visits to only 75%. Family practitioners were more likely than either pediatricians or psychiatrists to prescribe stimulants and less likely to use diagnostic services, provide mental health counseling, or recommend follow-up care. About 50% of children with identified ADHD seen in real-world practice settings receive care that corresponds to guidelines of the American Academy of Child and Adolescent Psychiatry. Physicians reported significant barriers to service provision for these children, including lack of pediatric specialists, insurance obstacles, and lengthy waiting lists. CONCLUSIONS: The trends in treatment services and physician variations in service delivery point to major gaps between the research base and clinical practice. Clinical variations may reflect training differences, unevenness in the availability of specialists and location of services, and changes in health care incentives.

Cerebrospinal fluid findings in aseptic versus bacterial meningitis.

BACKGROUND: Aseptic meningitis is often reported to be characterized by a mononuclear cell predominance in the cerebrospinal fluid (CSF), whereas bacterial meningitis is characterized by a polymorphonuclear (PMN) cell predominance. In contrast, other studies suggest that PMNs can be the most prevalent cell in early aseptic meningitis followed by a shift to mononuclear cells within 24 hours. These contradictory reports may lead to uncertainty in the diagnosis and treatment of meningitis. OBJECTIVES: To assess 1) the characteristics of the CSF differential in aseptic versus bacterial meningitis, 2) the influence of duration of illness on the CSF differential, and 3) the role of the CSF differential in discriminating between aseptic versus bacterial meningitis. METHODS: A retrospective chart review was conducted of all cases of meningitis in children >30 days of age hospitalized during the peak months for enteroviral meningitis (April to October) between 1992 to 1997. Cases of aseptic meningitis were defined as having at least 20 white blood cells/mm(3) and the absence of bacterial growth on culture. Patients were excluded if they received antibiotic therapy within the previous 5 days. Cases of bacterial meningitis were defined as having a positive culture of the CSF or the presence of a CSF pleocytosis with positive cultures of the blood. CSF variables including white blood cell differential and time from the onset of symptoms to the performance of a lumbar puncture were analyzed. PMNs were considered to be predominant when the percentage of neutrophils added to juvenile forms was >50% of cells. RESULTS: One hundred fifty-eight cases of meningitis were reviewed: 138 were aseptic and 20 were bacterial. The patients ranged in age from 30 days to 18 years; 61% were male. Fifty-seven percent of cases of aseptic meningitis had a PMN predominance. The percentage of PMNs in the CSF in patients with aseptic meningitis was not statistically different for patients who had a lumbar puncture performed either within or beyond 24 hours of the onset of symptoms. Fifty-one percent of the 53 patients with aseptic meningitis and duration of illness >24 hours had a PMN predominance. The ability of a PMN predominance to differentiate between aseptic and bacterial meningitis was assessed. The sensitivity of a PMN predominance for aseptic meningitis is 57% whereas the specificity is 10%. The positive predictive value of a PMN predominance for aseptic disease is 81% but the negative predictive value is 3%. Alternative definitions of PMN predominance from 60% to 90% were not useful as a clinical indicator of bacterial disease. CONCLUSIONS: The majority of children with aseptic meningitis have a PMN predominance in the CSF. The PMN predominance is not limited to the first 24 hours of illness. Because the majority of children with a PMN predominance during enteroviral season will have aseptic disease, a PMN predominance as a sole criterion does not discriminate between aseptic and bacterial meningitis.

Increasing identification of psychosocial problems: 1979-1996.

OBJECTIVE: To examine the changes in identification of pediatric psychosocial problems from 1979 to 1996. RESEARCH DESIGN: Comparison of clinician-identified psychosocial problems and related risk factors among large primary care pediatric cohorts from 1979 (Monroe County Study) and 1996 (Child Behavior Study). Data were collected from clinician visit questionnaires developed originally for the 1979 study. SETTING: Private practice offices of 425 community-based pediatricians and family practitioners across both studies. PATIENTS: We enrolled all children from 4 to 15 years of age who presented for nonemergent services in primary care offices. The 1979 study included 9612 children seen by 30 clinicians and the 1996 study included 21 065 children seen by 395 clinicians. SELECTION PROCEDURE: Each clinician enrolled consecutive eligible patients for both studies. MEASUREMENTS AND RESULTS: From 1979 to 1996, clinician-identified psychosocial problems increased from 6.8% to 18. 7% of all pediatric visits among 4- to 15-year-olds. We found increases in all categories of psychosocial problems, except for mental retardation. Attentional problems showed the greatest absolute increase (1.4%-9.2%) and emotional problems showed the greatest relative increase (.2%-3.6%). The use of psychotropic medications, counseling, and referral also increased substantially. In particular, the percentage of children with Attention deficit/hyperactivity problems receiving medications increased from 32% to 78%. These increases in psychosocial problems were associated with increases in the proportions of single-parent families and Medicaid enrollment from 1979 to 1996. Changes in clinician characteristics did not appear to be the source of increases in clinician diagnoses of psychosocial problems. CONCLUSIONS: Substantial increases in the identification of psychosocial problems in primary care paralleled demographic changes in children presenting to primary care offices and in the larger population.

Primary care treatment of pediatric psychosocial problems: A study from pediatric research in office settings and ambulatory sentinel practice network.

OBJECTIVE: Psychosocial problems cause much of the morbidity among children, and their frequency of presentation in primary care is growing. How is primary care treatment of children's psychosocial problems affected by child symptoms, physician training, practice structure, insurance, physician/patient relationship, and family demographics? DESIGN: Questionnaire study of treatment of psychosocial problems during office visits by children. SETTINGS: At total of 401 primary care offices from 44 US states, Puerto Rico, and Canada. PATIENTS: From 21 150 children seen in office visits, we selected children with an identified psychosocial problem but who were not already receiving specialty mental health services (n = 2618 children). OUTCOME MEASURES: Clinicians' decisions to counsel families, to refer children to mental health specialists, or to prescribe medication. RESULTS: The treatment choices of primary care clinicians (PCCs) were generally independent of patients' demographics or insurance status. Clinicians' training, beliefs about mental health, and practice structure had no effect on treatment choices. However, clinicians seeing their own patients were more likely to prescribe medications for attention problems. The clinician's perception about whether the parent agreed with the treatment choice was important for every treatment modality. Counseling and referral were more common and medication was less common when a problem was newly recognized at the visit. CONCLUSIONS: Structural factors such as practice type, insurance coverage, and physician training were less important for treatment than were process factors, such as whether the visit was a psychosocial problem visit, whether the problem was newly or previously recognized, and whether the family and clinician were familiar with each other and in accord about treatment.

Uninsured children with psychosocial problems: primary care management.

OBJECTIVE: Nearly 14% of children in the United States are uninsured. We compared the prevalence of psychosocial problems and mental health services received by insured and uninsured children in primary care practices. METHODS: The Child Behavior Study was a cohort study conducted by Pediatric Research in Office Settings and the Ambulatory Sentinel Practice Network. Four hundred one primary care clinicians enrolled an average sample of 55 consecutive children (4-15 years old) per clinician. RESULTS: Of the 13 401 visits to clinicians with 3 or more uninsured patients, 12 518 were by insured children (93.4%) and 883 were by uninsured children (6. 6%). A higher percentage of adolescents, Hispanic children, those with unmarried parents, and those with less educated parents were uninsured. According to clinicians, uninsured children and insured children had similar rates of psychosocial problems (19%) and severe psychosocial problems (2%). For children with a clinician-identified psychosocial problem, we found no differences in clinician-reported counseling, medication use, or referral to mental health professionals. CONCLUSIONS: Among children served in primary care practices, uninsured children have similar prevalence of clinician-identified psychosocial and mental health problems compared with insured children. Within their practices, clinicians managed uninsured children much the same way as insured children. psychosocial problems, uninsured children, pediatrics, family medicine, primary care.

Use of the Pediatric Symptom Checklist to screen for psychosocial problems in pediatric primary care: a national feasibility study.

BACKGROUND: Routine use of a brief psychosocial screening instrument has been proposed as a means of improving recognition, management, and referral of children's psychosocial morbidity in primary care. OBJECTIVE: To assess the feasibility of routine psychosocial screening using the Pediatric Symptom Checklist (PSC) in pediatrics by using a brief version of the checklist in a large sample representative of the full range of pediatric practice settings in the United States and Canada. We evaluated large-scale screening and the performance of the PSC in detecting psychosocial problems by (1) determining whether the prevalence of psychosocial dysfunction identified by the PSC was consistent with findings in previous, smaller samples; (2) assessing whether the prevalence of positive PSC screening scores varied by population subgroups; and (3) determining whether the PSC was completed by a significant proportion of parents from all subgroups and settings. PATIENTS AND METHODS: Twenty-one thousand sixty-five children between the ages of 4 and 15 years were seen in 2 large primary care networks: the Ambulatory Sentinel Practice Network and the Pediatric Research in Office Settings network, involving 395 pediatric and family practice clinicians in 44 states, Puerto Rico, and 4 Canadian provinces. Parents were asked to complete a brief questionnaire that included demographic information, history of mental health services, the 35-item PSC, and the number of pediatric visits within the past 6 months. RESULTS: The overall prevalence rates of psychosocial dysfunction as measured by the PSC in school-aged and preschool-aged pediatric outpatients (13% and 10%, respectively) were nearly identical to the rates that had been reported in several smaller samples (12%-14% among school-aged children and 7%-14% among preschoolers). Consistent with previous findings, children from low-income families were twice as likely to be scored as dysfunctional on the PSC than were children from higher-income families. Similarly, children from single-parent as opposed to those from 2-parent families and children with a past history of mental health services showed an elevated risk of psychosocial impairment. The current study was the first to demonstrate a 50% increase in risk of impairment for male children. The overall rate of completed forms was 97%, well within an acceptable range, and at least 94% of the parents in each sociodemographic subgroup completed the PSC form. CONCLUSIONS: Use of the PSC offers an approach to the recognition of psychosocial dysfunction that is sufficiently consistent across groups and locales to become part of comprehensive pediatric care in virtually all outpatient settings. In addition to its clinical utility, the consistency and widespread acceptability of the PSC make it well suited for the next generation of pediatric mental health services research, which can address whether earlier recognition of and intervention for psychosocial problems in pediatrics will lead to cost-effective outcomes.

Somatization in pediatric primary care: association with psychopathology, functional impairment, and use of services.

OBJECTIVE: To determine whether classification as pediatric "somatizers" identifies a group of children and adolescents at high risk for psychopathology, functional impairment, and frequent use of health services in a large, multisite study of pediatric primary care. METHOD: Parental reports of frequent aches and pains and visits to the doctor for medically unexplained symptoms in children aged 4 to 15 years were used to construct a classification of somatization in pediatric primary care. Affected and unaffected children and adolescents were compared on measures of demographics, family functioning, psychopathology, functional status, and service use. RESULTS: Classification as a somatizer was more common in adolescents, females, minority subjects, urban practices, nonintact families, and families with lower levels of parental education and was associated with heightened risk of clinician- and parent-identified psychopathology, family dysfunction, poor school performance and attendance, perceived health impairment, and more frequent use of health and mental health services. CONCLUSIONS: Children classified as pediatric somatizers are at heightened risk for psychiatric disorder, family dysfunction, functional impairment, and frequent use of health services. Additional research is warranted, and clinicians should recognize the need for careful assessment and potential behavioral health referral in this population.

The Physician Belief Scale and psychosocial problems in children: a report from the Pediatric Research in Office Settings and the Ambulatory Sentinel Practice Network.

Clinicians' management of children with psychosocial problems may vary with their attitudes and beliefs. However, we lack sound instruments to assess these factors. This study examined the psychometric properties of the Physician Belief Scale (PBS). A modified version of the PBS was sent to clinicians who participated in two primary care research networks. Using factor analysis, we reduced the PBS to 14 items and 2 subscales. Cronbach's alpha values were high. Female clinicians, those using DSM-IV, and those having completed training earlier rated themselves as more psychosocially oriented. Identification and treatment of psychosocial problems were significantly related to scores on the Belief and Feeling subscale. The PBS provided only a modest amount of information regarding primary care practices. It is not clear if these limitations are attributable to the instrument or the many other barriers to effective psychosocial care.

A fork in the road: decision time for behavioral pediatrics.

The rapid growth of managed care, and especially that of managed behavioral healthcare organizations (MBHOs), is likely to diminish the role of developmental-behavioral pediatrics and separate care for medical and behavioral problems. Thus, a rethinking of the practice of developmental-behavioral pediatrics is required. This study reviews the structure of MBHOs, identifies barriers to the provision of services by developmental-behavioral pediatricians, describes alternative practice models for consideration, and makes recommendations. The aims of the recommendations are to stimulate an active discussion about these issues, spark an advocacy effort, and ensure the continued participation of developmental-behavioral pediatricians in the care of children with special needs. The study concludes that managed care will push developmental-behavioral pediatricians into integration with primary care group practices or into specialty mental health networks. Immediate discussion, action, and advocacy will be required to ensure a presence in these decisions for developmental-behavioral pediatricians.

Patient race and ethnicity in primary care management of child behavior problems: a report from PROS and ASPN. Pediatric Research in Office Settings. Ambulatory Sentinel Practice Network.

BACKGROUND: Minority persons have less access to many specialty treatments and services, possibly because of clinician biases. It is not clear whether any such biases exist in primary care settings, especially for children with psychosocial problems. OBJECTIVES: The objective was to compare primary care recognition and treatment of pediatric psychosocial problems among African American, Hispanic American and European American patients. DESIGN: A survey was made of parents and respective clinicians in primary care offices in two large practice-based research networks (PROS and ASPN) from 44 states, Canada, and Puerto Rico. Mixed regression analyses were employed to control for patient, clinician, and practice effects. SUBJECTS: The subjects were 14,910 children aged 4 to 15 years seen consecutively for non-emergent care by 286 primary care clinicians in office-based practice. MEASURES: Measures were parents' report for sociodemographics and behavioral symptoms using the Pediatric Symptom Checklist, and clinicians' report of psychosocial problems, type, management, and severity. RESULTS: Of the sample, 8.0% were African American youth, 9.5% were Hispanic American youth, and 82.5% were European American youth. After controlling for other factors, race and ethnicity were not associated with any differences in psychotropic drug prescribing, counseling, referral, or recognition of psychosocial problems. Clinicians reported spending slightly more time with minority patients. CONCLUSION: Race and ethnic status were not related to receipt of mental health services for children in primary care offices, suggesting that clinician biases may not be the primary cause of the racial differences in services noted earlier research. Improving services for minority youth may require increasing access to office-based primary care.

Identification of attentional and hyperactivity problems in primary care: a report from pediatric research in office settings and the ambulatory sentinel practice network.

OBJECTIVES: To 1) determine the frequency of identification of attentional and hyperactivity problems (AHPs) by clinicians, and 2) examine whether minority children or children from less well-educated, lower-income, or lower-functioning families would be more likely to be identified as having AHPs. DESIGN: Prospective cohort study of 22 059 consecutive children 4 to 15 years of age being seen for acute, chronic, and health supervision visits. SETTING: Practices of 401 pediatric and family practice clinicians in 44 states, Puerto Rico, and 4 Canadian provinces. METHODS: Parent questionnaires included demographic information and the Pediatric Symptom Checklist. Clinician questionnaires categorized psychosocial problems and addressed how assessment of problems was made. Analyses compared children with newly identified AHPs with those with other newly identified psychosocial problems. RESULTS: Clinicians identified behavior problems in 18.7% of children, with 9.2% of the entire sample identified as having AHPs. Among those with newly assessed AHPs, clinicians identified minority children and those from low-income or poorly functioning families as having AHPs at the same rate as other children. However, even after controlling for symptoms, males were more likely than females (odds ratio, 2.81) to be identified as having AHPs. Older clinicians were significantly more likely to identify children as having AHPs (odds ratio, 2.09). In assessing AHPs, clinicians used standardized tools such as behavioral questionnaires for only 36.9% of children, and Diagnostic and Statistical Manual criteria for 38.3% of children. CONCLUSIONS: AHPs are highly prevalent in primary care practice. Clinicians do not appear predisposed to label children from disadvantaged backgrounds as having AHPs. Primary care assessment of AHPs lacks standardization.
