Will pediatricians adopt the new rotavirus vaccine?

OBJECTIVES: Our objective was to determine the following among US pediatricians: (1) perceptions regarding burden of rotavirus disease and need for a vaccine; (2) intentions for recommending a newly licensed rotavirus vaccine; (3) perceived barriers to implementation; and (4) factors associated with plans for vaccine adoption. PATIENTS AND METHODS: A network of 431 pediatricians was recruited from a random sample of American Academy of Pediatrics' members. The network was designed to be representative of the American Academy of Pediatrics with respect to region of the country, practice type, and practice setting. During January and February 2006, physicians were surveyed by Internet or mail. The survey contained a paragraph summarizing results of the new rotavirus vaccine trial. Respondents were asked about intentions to use the vaccine and anticipated barriers. RESULTS: The survey response rate was 71%. Of the respondents, 52% strongly agreed and 37% somewhat agreed with the need for a rotavirus vaccine. If recommended for routine use, 50% would strongly recommend and 34% would recommend but not strongly; 52% would begin to use within 6 months and 27% from 6 months to 1 year. The top 3 "definite" barriers to implementation included concerns about uniform coverage of vaccine by insurers, lack of adequate reimbursement, and parental reluctance because of withdrawal of previous rotavirus vaccine. In multivariate analysis, factors associated with very likely adoption of the vaccine included perception of a high burden of rotavirus disease and a high level of confidence in prelicensure studies of vaccine safety. The presence of physician concerns about safety of the new vaccine and the perception of parental concerns about vaccine safety in general were negatively associated with adoption. CONCLUSIONS: The majority of pediatricians reported willingness to implement the new rotavirus vaccine, most within 6 months. Major barriers to optimal implementation included provider concerns about reimbursement issues and parental acceptance of the vaccine.

Symptom distress and quality-of-life assessment at the end of life: the role of proxy response.

This study sought to advance understanding of the relationships among proxy and patient reports of symptom distress and quality of life (QOL). English-speaking adults (n=86), their nurses (n=86), and family caregivers (n=49) from 11 hospice/palliative care organizations completed the Memorial Symptom Assessment Scale (MSAS) and McGill Quality of Life Questionnaire (MQOL) at hospice/palliative care enrollment, at 1 week, 2 weeks, then monthly until death or discharge. Patients and proxies provided similar average reports of symptom distress, both physical and psychological, but MSAS correlations were generally poor. MQOL correlations were higher for nurse-patient than for patient-caregiver dyads. Based on small differences between ratings but only moderate levels of correlation, proxy response appears to be a fair substitute for patient response, suggesting that symptom and QOL reports should be obtained from all available respondents throughout the course of clinical care or research in the hospice/palliative care setting.

Influenza vaccine effectiveness in healthy 6- to 21-month-old children during the 2003-2004 season.

OBJECTIVE: To assess the clinical effectiveness of influenza vaccine in preventing influenza-like illness (ILI) office visits. STUDY DESIGN: We analyzed billing and immunization registry data for healthy 6- to 21-month-olds from 5 Denver, Colorado pediatric practices (n = 5193). ILI and pneumonia/influenza (a subset of ILI) were defined from International Classification of Diseases, Ninth Revision, Clinical Modification codes for office visits occurring during peak influenza season. Partially vaccinated (PV) and fully vaccinated (FV) patients were defined as having 1 shot and 2 shots, respectively, more than 14 days before the first ILI visit. The likelihood of an ILI visit was determined using a Cox proportional hazards model accounting for patient characteristics, practice site, and immunization status. RESULTS: A total of 28% of the patients had an ILI office visit, and 5% had a pneumonia/influenza visit. Hazard ratios (HRs) for FV versus UV were 0.31 (95% confidence interval [CI] = 0.3 to 0.4) for ILI and 0.13 (95% CI = 0.1 to 0.2) for pneumonia/influenza, corresponding to a vaccine effectiveness (1 - HR x 100) of 69% for ILI and 87% for pneumonia/influenza. The corresponding HRs for PV versus UV were 1.0 (95% CI = 0.9 to 1.2) and 1.1 (95% CI = 0.8 to 1.5). CONCLUSIONS: Although 2 doses of vaccine were 69% effective against ILI office visits and 87% effective against pneumonia/influenza office visits, 1 dose did not prevent office visits during the 2003-2004 influenza season.

The influence of patient race and social vulnerability on urologist treatment recommendations in localized prostate carcinoma.

BACKGROUND: In localized prostate carcinoma (PCa), many studies have found that black subjects receive radical prostatectomy (RP) less often than white subjects. Such disparities involve barriers to health care, comorbid illnesses, tumor characteristics, and patient preferences. It is unclear whether differences in urologist treatment recommendations also might play a role. METHODS: Using a randomized, 2 x 2 factorial design, we presented 2000 urologists with a clinical vignette and asked them to recommend treatment of a healthy 70-year-old patient with low-risk, clinically localized PCa. Options included either RP, external beam radiotherapy, brachytherapy, cryotherapy, observation, or hormonal therapy. There were 2 variables within 4 otherwise-identical versions of the vignette: 1) patient race (black vs. white) and 2) social vulnerability (middle-income and married vs. low-income and widowed). We used multivariable logistic regression to model the effects of patient race, social vulnerability, and their interaction on recommendations for RP versus radiotherapy. RESULTS: The response rate was 66.1% (n = 1313). Race and social vulnerability interacted (P = 0.05) such that the highly vulnerable black patient received an RP recommendation 14.4% less often than his less vulnerable counterpart; the difference between the 2 white patients was 4.2%. DISCUSSION: Race interacts with social vulnerability to influence urologist recommendations for RP. Because PCa tends to be more lethal in blacks, urologists may view such patients as good candidates for RP. However, black race may amplify perceptions of social vulnerability, heightening urologists' concerns about poor surgical outcomes and follow-up. These findings affirm the importance of modeling interactions between race/ethnicity and other social variables in health disparities research.

Influenza among healthy young children: changes in parental attitudes and predictors of immunization during the 2003 to 2004 influenza season.

BACKGROUND: In Colorado, the 2003 to 2004 influenza season was unusually early and severe and received substantial media attention. OBJECTIVES: Among parents of healthy young children, to determine how parental knowledge and attitudes regarding influenza infection and immunization changed during the 2003 to 2004 influenza season and to identify factors predictive of influenza immunization. METHODS: The study was conducted in 5 metropolitan Denver pediatric practices. A total of 839 healthy children age 6 to 21 months and their parents were randomly selected for participation. Parents were surveyed by telephone before (August 18 to October 7, 2003) and after (March 31 to June 10, 2004) the influenza season. RESULTS: Among 828 eligible parents, 472 (57%) completed the preseason survey; 316 (67%) of these parents subsequently completed the postseason survey. All analyses were performed for the 316 subjects who completed both preseason and postseason surveys. Compared with their attitudes before the influenza season, 48% of parents interviewed after the season viewed their child as more susceptible to influenza, 58% viewed influenza infections as more severe, and 66% perceived fewer risks associated with influenza vaccine. Ninety-five percent of parents reported hearing in the media about Colorado's influenza outbreak, and having heard about the outbreak in the media was associated with viewing influenza infections as more severe. A total of 258 parents (82%) immunized their child against influenza. In multivariate analyses, positive predictors of immunization included a physician recommendation for immunization and a preseason to postseason increase in the perception that immunization was the social norm. Negative predictors of immunization included high perceived barriers to immunization, less parental education, and preseason intention not to immunize. CONCLUSIONS: Parent attitudes about influenza infection and immunization changed substantially during the 2003 to 2004 influenza season, with changes favoring increased parental acceptance of influenza vaccination for young children. During an intensively publicized influenza outbreak, a physician recommendation of vaccination was an important predictor of influenza immunization.

A national survey of pediatrician knowledge and attitudes regarding human papillomavirus vaccination.

OBJECTIVE: A human papillomavirus vaccine was licensed in June 2006. The vaccine is quadrivalent, protecting against 2 human papillomavirus strains that cause cervical cancer and 2 that cause genital warts. The objective of this study was to determine physician characteristics, knowledge, and attitudes associated with an intention to recommend human papillomavirus vaccination. METHODS: Between August and October 2005, a cross-sectional survey was administered to a national network of 431 pediatricians. The network was developed from a random sample of American Academy of Pediatrics members and was designed to be representative of the organization's membership with respect to urban/rural location, practice type, and region. The survey was conducted before human papillomavirus vaccine licensure and therefore focused on a candidate quadrivalent human papillomavirus vaccine and a range of potential vaccination recommendations. The main outcome measure was intention to recommend a quadrivalent human papillomavirus vaccine to young adolescent (10- to 12-year-old) females. RESULTS: Survey response rate was 68%. If endorsed by national health organizations, 46% of respondents would recommend vaccination for 10- to 12-year-old females, 77% for 13- to 15-year-old females, and 89% for 16- to 18-year-old females. Corresponding rates for males were 37%, 67%, and 82%, respectively. Whereas 60% of respondents thought that parents would be concerned that human papillomavirus vaccination may encourage risky sexual behaviors, 11% reported that they themselves had this concern. Respondents who believed that other new adolescent immunization recommendations (eg, meningococcal, pertussis) would facilitate human papillomavirus vaccine implementation were more likely to intend to recommend vaccination. CONCLUSIONS: Although a national sample of pediatricians expressed a high level of acceptance of human papillomavirus vaccination in older adolescent females, fewer than one half anticipated giving human papillomavirus vaccine to younger female patients. Provider concerns about parental vaccine acceptance will need to be addressed to optimize human papillomavirus vaccination implementation.

An Internet-based patient-provider communication system: randomized controlled trial.

BACKGROUND: Internet-based interactive websites for patient communication (patient portals) may improve communication between patients and their clinics and physicians. OBJECTIVE: The aim of the study was to assess the impact of a patient portal on patients' satisfaction with access to their clinic and clinical care. Another aim was to analyze the content and volume of email messages and telephone calls from patients to their clinic. METHODS: This was a randomized controlled trial with 606 patients from an academic internal medicine practice. The intervention "portal" group used a patient portal to send secure messages directly to their physicians and to request appointments, prescription refills, and referrals. The control group received usual care. We assessed patient satisfaction at the end of the 6-month trial period and compared the content of telephone and portal communications. RESULTS: Portal group patients reported improved communication with the clinic (portal: 77/174 [44%] "a little better" or "a lot better;" control: 18/146 [12%]; chi2 = 38.8, df = 1, P < .001) and higher satisfaction with overall care (portal: 103/174 [59%] "very good" or "excellent;" control: 78/162 [48%]; chi2 = 4.1, df = 1, P = .04). Portal group patients also reported higher satisfaction with each of the portal's services. Physicians received 1 portal message per day for every 250 portal patients. Total telephone call volume was not affected. Patients were more likely to send informational and psychosocial messages by portal than by phone. Of all surveyed patients, 162/341 (48%) were willing to pay for online correspondence with their physician. Of those willing to pay, the median amount cited was 2 USD per message. CONCLUSIONS: Portal group patients demonstrated increased satisfaction with communication and overall care. Patients in the portal group particularly valued the portal's convenience, reduced communication barriers, and direct physician responses. More online messages from patients contained informational and psychosocial content compared to telephone calls, which may enhance the patient-physician relationship.

Expectations of patients and physicians regarding patient-accessible medical records.

BACKGROUND: Middle class populations have supported shared medical records, including Internet-accessible medical records. The attitudes of lower income populations, and of physicians, are less clear. OBJECTIVES: The objective of this study was to compare the attitudes toward shared outpatient medical records among (1) socioeconomically disadvantaged patients in community health centers, (2) insured patients in primary care offices, and (3) a broad range of physicians in outpatient practice. METHODS: Written questionnaires were provided to patients in the waiting rooms of six primary care practices in the metropolitan Denver, Colorado area. Three practices were community health centers, and three practices were primary care clinics of an academic medical center. Questionnaires were also mailed to primary care physicians in the state of Colorado. RESULTS: There was a 79% response rate for patient surveys (601 surveys returned) and a 53% response rate for physician surveys (564 surveys returned). Academic medical center patients and community health center patients were equally likely to endorse shared medical records (94% vs 96%) and Internet-accessible records (54% vs 57%). Community health center patients were more likely than academic medical center patients to anticipate the benefits of shared medical records (mean number of expected benefits = 7.9 vs 7.1, P < .001), and they were also somewhat more likely to anticipate problems with shared records. Significant predictors of patient endorsement of Internet-accessible records were previous use of the Internet (OR = 2.45, CI 1.59-3.79), the number of expected benefits (OR = 1.12 per unit, CI 1.03-1.21), anticipation of asking more questions between visits (OR = 1.73, CI 1.18-2.54), and anticipation of finding the doctors' notes to be confusing (OR = 1.50, CI 1.01-2.22). Physicians were significantly more likely than patients to anticipate that access to records would cause problems. Physicians were significantly less likely than patients to anticipate benefits (mean number of expected benefits = 4.2 vs 7.5, P < .001). CONCLUSIONS: Interest in shared medical records is not confined to a white, middle class population. Shared medical records are almost universally endorsed across a broad range of ethnic and socioeconomic groups. A majority of patients are also interested in Internet-accessible records, but a substantial minority is not. The primary determinants of support of Internet-accessible records are not age, race, or education level; rather, they are previous experience with the Internet and patients' expectations of the benefits and drawbacks of reading their medical records. Physicians have more concerns about shared medical records and see less potential for benefit. The attitudes of patients and physicians may need to be reconciled for widespread adoption of shared medial records to be achieved.

Marriage and ethnicity predict treatment in localized prostate carcinoma.

BACKGROUND: Primary treatment for early-stage prostate carcinoma includes expectant management or, for curative intent, radical prostatectomy or radiotherapy. Treatment recommendations are generally guided by clinical factors such as Gleason grade, prostate-specific antigen level, comorbid illnesses, and patient age. Sociocultural factors may also have influences on patient and urologist treatment choices. METHODS: The authors used bivariate and multinomial logistic regression to identify medical and sociodemographic predictors of prostatectomy (compared with radiotherapy) and curative therapy (compared with expectant management) in a cohort of 27,920 non-Latino white, black, and Latino men without comorbidities in the latest linked Surveillance, Epidemiology and End Results-Medicare dataset (years 1995-1999). Predictors included tumor stage, patient age, marital status, race/ethnicity, and socioeconomic status. RESULTS: Younger age and higher tumor grade were robust predictors of curative treatment compared with expectant management and of prostatectomy compared with radiotherapy. Sociodemographic factors had an additive role in treatment choice. Marriage predicted curative treatment compared with expectant management (adjusted risk ratio [RR] = 1.28 [1.25-1.30]) and prostatectomy compared with radiotherapy (adjusted RR = 1.24 [1.20-1.28]). Although blacks and Latinos were just as likely as whites to receive curative treatment, blacks were significantly less likely, whereas Latinos were more likely, to receive prostatectomy compared with radiotherapy (adjusted RRs = 0.77 [0.72-83]) and 1.24 [1.18-1.30], respectively). CONCLUSIONS: Marriage was positively associated with curative treatment in general, and with prostatectomy specifically. Blacks received prostatectomy less often than whites, although they did not receive less curative treatment overall. Latinos received prostatectomy more often than whites. Clinicians should recognize the importance of cultural and social forces as well as biomedical factors in decisions regarding the treatment of patients with early-stage prostate carcinoma.

Missed opportunities for influenza vaccination in children with chronic medical conditions.

OBJECTIVES: To assess the frequency and characteristics of missed opportunities for influenza immunization in children with chronic medical conditions and, among unimmunized children in that group, to explore parent-reported reasons for not vaccinating their child. DESIGN: Prospective cohort study. Data were obtained from billing and immunization registry databases and telephone interviews of parents. SETTING: Four pediatric practices in metropolitan Denver, Colo, during the 2002-2003 influenza season. PARTICIPANTS: Children aged 6 to 72 months with 1 or more chronic medical conditions. Main Outcome Measure A missed opportunity for influenza immunization, defined as having a billed encounter, being eligible for immunization, and not receiving vaccine. Subjects with asthma were analyzed separately from those with other conditions. RESULTS: We identified 926 children with chronic conditions: 820 (89%) with asthma only and 106 (11%) with other conditions. Missed opportunities occurred at 78% of all vaccine-eligible visits for children with asthma and 74% of all visits for children with other conditions. For children with asthma, 92% of vaccine-eligible visits in December and January resulted in a missed opportunity vs 69% in October and November; for children with other conditions, corresponding frequencies were 86% vs 68%, respectively. For children with asthma, 86% of non-well-child visits resulted in a missed opportunity, compared with 62% of well-child visits; similar frequencies were seen among children with other chronic conditions. Parents of unimmunized children reported lack of a physician recommendation and low perceived susceptibility to influenza as the primary reasons for not immunizing their child. CONCLUSION: Missed opportunities contribute significantly to low influenza immunization rates among children with chronic medical conditions.

Predictors of nonadherence to screening colonoscopy.

BACKGROUND: Colonoscopy has become a preferred colorectal cancer (CRC) screening modality. Little is known about why patients who are referred for colonoscopy do not complete the recommended procedures. Prior adherence studies have evaluated colonoscopy only in combination with flexible sigmoidoscopy, failed to differentiate between screening and diagnostic procedures, and have examined cancellations/no-shows, but not nonscheduling, as mechanisms of nonadherence. METHODS: Sociodemographic predictors of screening completion were assessed in a retrospective cohort of 647 patients referred for colonoscopy at a major university hospital. Then, using a qualitative study design, a convenience sample of patients who never completed screening after referral (n=52) was interviewed by telephone, and comparisons in reported reasons for nonadherence were made by gender. RESULTS: Half of all patients referred for colonoscopy failed to complete the procedure, overwhelmingly because of nonscheduling. In multivariable analysis, female sex, younger age, and insurance type predicted poorer adherence. Patient-reported barriers to screening completion included cognitive-emotional factors (e.g., lack of perceived risk for CRC, fear of pain, and concerns about modesty and the bowel preparation), logistic obstacles (e.g., cost, other health problems, and competing demands), and health system barriers (e.g., scheduling challenges, long waiting times). Women reported more concerns about modesty and other aspects of the procedure than men. Only 40% of patients were aware of alternative screening options. CONCLUSIONS: Adherence to screening colonoscopy referrals is sub-optimal and may be improved by better communication with patients, counseling to help resolve logistic barriers, and improvements in colonoscopy referral and scheduling mechanisms.

Changes in access, utilization, and quality of care after enrollment into a state child health insurance plan.

BACKGROUND: There currently are few published data evaluating the effect of State Children's Health Insurance Programs on health care outcome measures in children. Colorado's Child Health Plan Plus (CHP+) is a non-Medicaid State Children's Health Insurance Program that began enrollment in April 1998. The objectives of this study were to compare reported (1) access to care, (2) utilization of health care, and (3) quality of care during the year before and the first year after enrollment into CHP+. METHODS: We interviewed 480 randomly selected families by telephone 2 months after their first enrollment into CHP+ (September 1999 to January 2000) and, again, 1 year later. We used generalized linear models to examine the effect of enrollment on health care access, utilization, and quality while controlling for type of previous insurance, length of time uninsured before enrollment, race/ethnicity, and age. RESULTS: Regarding access to care, the percentage of families who reported a usual site of preventive care did not change significantly, but families reported more often being able to see providers as soon as desired for routine care (incidence ratio [IR]: 2.03; 95% confidence interval [CI]: 1.37-3.02]), for care when sick or injured (IR: 2.77; 95% CI: 1.85-4.16), for specialty care (IR: 1.96; 95% CI: 1.16-3.32), and for all health care (IR: 2.35; 95% CI: 1.81-3.07). Unmet medical needs decreased after versus before enrollment for prescription medications (IR: 0.38; 95% CI: 0.26-0.55), mental health care (IR: 0.63; 95% CI: 0.40-0.97), prescription glasses (IR: 0.44; 95% CI: 0.29-0.65), and dental care (IR: 0.59; 95% CI: 0.47-0.76). Regarding utilization, the proportion who saw a provider for routine care in the past year increased (IR: 1.39; 95% CI: 1.06-1.83), but reported visits for sick, specialty, and emergency department care and hospitalizations did not increase. Regarding quality of care, the proportion who rated their health care as "best" increased (RI: 1.31; 95% CI: 1.04-1.66) after versus before enrollment. CONCLUSIONS: Families who were newly enrolled into CHP+ perceived dramatic increases in access to all types of care and decreases in unmet medical needs, no increase in utilization of emergency department or hospitalization services, and improved overall quality of care in the year after enrollment into CHP+.

Implementation of universal influenza immunization recommendations for healthy young children: results of a randomized, controlled trial with registry-based recall.

BACKGROUND: An Advisory Committee on Immunization Practices policy of encouraging influenza vaccination for healthy 6- to 23-month-old children was in effect during the 2003-2004 influenza season, which was unusually severe in Colorado. We collaborated with 5 pediatric practices to attempt universal influenza immunization in this age group. OBJECTIVES: The objectives were (1) to assess the maximal influenza immunization rates that could be achieved for healthy young children in private practice settings, (2) to evaluate the efficacy of registry-based reminder/recall for influenza vaccination, and (3) to describe methods used by private practices to implement the recommendations. METHODS: The study was conducted in 5 private pediatric practices in Denver, Colorado, with a common billing system and immunization registry. Although recommendations by the Advisory Committee on Immunization Practices included children who were 6 to 23 months of age at any point during the influenza season, our practices chose not to recall children 22 to 23 months of age, because they would have become >24 months of age during the study period. Therefore, our study population consisted of all healthy children 6 to 21 months of age from the 5 practices (N = 5193), who were randomized to intervention groups (n = 2595) that received up to 3 reminder/recall letters or to control groups (n = 2598) that received usual care. The primary outcome was receipt of >or=1 influenza immunization, as noted either in the immunization registry or in billing data. RESULTS: Immunization rates for >or=1 dose of influenza vaccine for the intervention groups in the 5 practices were 75.9%, 75.4%, 68.1%, 55.6%, and 44.3% at the end of the season. Overall, 62.4% of children in the intervention groups and 58.0% of children in the control groups were immunized (4.4% absolute difference), with absolute differences, compared with control values, ranging from 1.0% to 9.1% according to practice. However, before intensive media coverage of the influenza outbreak began (November 15, 2003), absolute differences, compared with control values, ranged from 5.1% to 15.3% and were 9.6% overall. Before November 15, significant effects of recall were seen for children in the intervention groups, in both the 12- to 21-month age category (10.4% increase over control) and the 6- to 11-month category (8.1% increase over control); at the end of the season, however, significant effects of recall were seen only for the older age group (6.2% increase over control). The rates of receipt of 2 vaccine doses >or=1 month apart for eligible children ranged from 21% to 48% among the practices. Four of the 5 practices held influenza immunization clinics during office hours, evenings, or weekends, and these clinics achieved higher coverage rates. CONCLUSIONS: These results demonstrated that, in an epidemic influenza year, private practices were able to immunize the majority of 6- to 21-month-old children in a timely manner. Although media coverage regarding the epidemic blunted the effect of registry-based recall, recall was effective in increasing rates early in the epidemic, especially for children between 1 and 2 years of age. The practices that achieved the highest immunization rates were proactive in planning influenza clinics to handle the extra volume of immunizations required.

Differences in fat and lean mass proportions in normal and growth-restricted fetuses.

OBJECTIVE: The purpose of this study was to assess fetal subcutaneous fat and lean mass areas as predictors of fetal growth restriction. STUDY DESIGN: Seventeen severe fetal growth-restricted (abdominal circumference, < 2 SD) fetuses and 20 control fetuses underwent ultrasound measurements of subcutaneous fat, lean mass, and standard biometry. Thigh subcutaneous fat and lean mass were measured on enlarged ultrasound axial images (subcutaneous fat area = total cross sectional area - lean mass area [bone + muscle areas]). Subcutaneous fat and lean mass areas were expressed as a percentage of the total cross-sectional area and were normalized to femur length and head circumference. Measurements were modeled as a function of fetal growth-restriction status and week of gestation with multiple linear regression. RESULTS: Fetal growth-restriction fetuses showed reductions in fat and lean mass (in standard biometry) and showed a disproportionate reduction in fat mass compared with lean mass. These were all associated significantly with fetal growth restriction. CONCLUSION: Fetal growth-restricted fetuses have reduced subcutaneous fat and lean mass compared with control fetuses; a further reduction occurs in subcutaneous fat concentration compared with the reduction in lean mass when fat is normalized for body size, with either head circumference or femur length. Fat-to-bone proportions may be useful in distinguishing the small for gestational age fetus who is truly fetal growth restriction from the constitutionally small fetus.

Outcomes and characteristics of patients discharged alive from hospice.

OBJECTIVES: To describe outcomes and characteristics of patients discharged alive from hospice. DESIGN: Prospective cohort study using a telephone survey. SETTING: Hospices (n=18) participating in the Population-Based Palliative Care Research Network during the 1-year study period. PARTICIPANTS: English-speaking adults (n=164) who were discharged alive from participating hospices during the 1-year study period. MEASUREMENTS: Mortality within 6 months of hospice discharge. RESULTS: Thirty-five percent (n=48) of the 139 patients with known outcomes died within 6 months of hospice discharge, 15 of whom (31%) died without hospice readmission. There were no significant associations between sex (P=.77), length of hospice service (P=.99), diagnosis (P=.73), discharge disposition (P=.54), admission evidence of prognosis of less than 6 months to live (P=.22-.95), Karnofsky score at admission or change between admission and discharge (P=.39, P=.38, respectively), or duration of hospice care after stabilization (P=.83) and mortality within 6 months after hospice discharge. Age (P=.11), discharge Karnofsky score (P=.17), and reason for discharge being improved or stabilized condition (P=.13) trended toward statistical significance. The strongest predictor of mortality after hospice discharge was a report that the patient's condition had worsened (hazard ratio=10.2, 95% confidence interval 4.5-23.4). CONCLUSION: One-third of patients who were discharged from hospice died within 6 months of hospice discharge, indicating ongoing eligibility for hospice care even under the strictest interpretation of hospice eligibility criteria. Patients who are discharged from hospice care should be evaluated frequently, especially within the first weeks to months after discharge, for changes in status, unmet needs, and potential hospice readmission.

The cost of giving childhood vaccinations: differences among provider types.

OBJECTIVE: To describe costs to providers of delivering childhood immunizations. METHODS: We collected variable costs--costs that vary with the amount of services rendered--including cost of practitioner and staff time and supplies, using a cost accounting method, from 12 practices (4 pediatric practices, 4 family practices, and 4 public health agencies) in rural and urban areas in Colorado. For private practices, we estimated fixed costs--costs that do not vary with the amount of services, eg, rent and insurance). We also collected reimbursement information for vaccinations for private practices. RESULTS: Variable costs per shot (excluding vaccine cost) were 8.15 dollars for pediatric practices, 5.79 dollars for family practices, and 5.41 dollars for public health agencies. Total costs per shot, including fixed costs, were 10.67 dollars for pediatric practices and 7.57 dollars for family practices. Average reimbursement for pediatricians and private family practices was 8.27 dollars and 6.68 dollars, respectively. For pediatric practices, average variable costs were barely exceeded by average reimbursement, and reimbursement was 22% less than average total costs. This contrasts with an earlier study of the rural practices investigated here, in which there was a comfortable margin between reimbursement and variable costs. CONCLUSION: The decline in the ratio of reimbursement to cost for private practices, particularly for pediatric practices, suggests that referral to public agencies by private providers for vaccinations may increase and that if vaccinations are not as frequently provided in the child's medical home, then the currently high childhood immunization rates may be in jeopardy.

The regional immunization registry as a public health tool for improving clinical practice and guiding immunization delivery policy.

OBJECTIVES: We assessed the distribution of immunization records among 3 health care delivery sectors and the impact of a regional immunization registry on "up to date" rates. METHODS: Immunization registry records in 2 regions were categorized as having originated in private practices, community health centers, or public health clinics. "Up to date" rates were calculated after we sequentially added immunization records from the 3 sectors. RESULTS: The percentage of children with immunizations documented in multiple sectors increased with age from 7 to 24 months, and children who were seen in multiple sectors were more likely to be up to date. There were relative increases in "up to date" rates of 50% for children aged 24 months. CONCLUSIONS: The regional immunization registry is a powerful public health tool for increasing documented "up to date" rates and providing insights into patterns of immunization delivery.

Immunization registry accuracy: improvement with progressive clinical application.

BACKGROUND: Healthcare systems have been challenged to ensure the timely administration of immunizations. Immunization registries have been proposed to improve the accuracy and completeness of immunization information and to promote effective practice. METHODS: Comparison of randomly selected samples from two birth cohorts (1993 and 1998) from Denver Health Medical Center. Chart review and immunization registry information for these groups were compared; a composite immunization was recorded and up-to-date (UTD) status established. Registry data were compared with this composite using a sensitivity measure to assess completeness and accuracy. RESULTS: Among 818 children in the 1993 cohort and 1043 children in the 1998 cohort, there were 6386 and 6886 valid immunizations, respectively. The registry recorded 71.4% and 97.7% of these for the 1993 and 1998 cohorts, respectively (p <0.001). The apparent UTD rate, as measured with registry data alone, improved from 37% to 79% between the two time frames (p <0.001). Composite UTD status was 83.1% and 78.9% (1993 vs 1998, respectively). Accurate registry-defined UTD status improved from 44.4% to 100% between the two intervals. CONCLUSIONS: Immunization registry accuracy improved dramatically for recorded immunizations and UTD status. However, after 3 years of registry use, the overall proportion of children who were UTD had not significantly improved. The mere presence of a registry does not ensure more complete vaccination coverage. Other registry-based strategies, including use of the data for reminder, recall, and audit, may further improve immunization coverage.
