Pediatric Telephone Call Centers: How Do They Affect Health Care Use and Costs?

OBJECTIVES. After-hours call centers have been shown to provide appropriate triage with high levels of parental and provider satisfaction. However, few data are available on the costs and outcomes of call centers from the perspective of the health care system. With this study we sought to determine these outcomes. METHODS. Parents who called the Pediatric After-hours Call Center at the Childrens Hospital of Denver from March 19, 2004, to April 19, 2004, were asked an open-ended question before triage: “We would like to know, what you would have done if you could not have called our call center this evening/today?” RESULTS. The response rate for the survey was 77.8% (N = 8980). Parents reported that they would have (1) gone to an emergency department or urgent care facility (46%), (2) treated the child at home (21%), (3) called a physicians office the next day (12%), (4) asked another person for advice (13%), (5) consulted a written source (2%), or (6) other (7%). Of the 46% of callers who would have sought emergent care, only 13.5% subsequently were given an urgent disposition by the call center. Fifteen percent of cases in which the parents would have stayed at home were given an urgent disposition by nurses. Assuming that all callers followed the advice provided, the estimated savings per call, based on local costs, was

Practice Facilitation to Improve Diabetes Care in Primary Care: A Report From the EPIC Randomized Clinical Trial

56.26 per call. CONCLUSIONS. Two thirds of the cases in which parents reported initial intent to go to an emergency department or urgent care facility were not deemed urgent by the call center, whereas 15% of calls from parents who intended to stay home were deemed urgent. If call-center triage recommendations were followed in even half of all cases, then these results would translate into substantial cost savings for the health care system.

Lack of Impact of Direct-to-Consumer Advertising on the Physician-Patient Encounter in Primary Care: A SNOCAP Report

BACKGROUND Electrocardiographic criteria for the diagnosis of left ventricular hypertrophy in current use were defined using autopsy results or echocardiography; criteria defined using mortality might be more clinically meaningful. METHODS Using data from Third National Health and Nutrition Examination Survey (NHANES III), we selected electrocardiographic measures that best differentiated those surviving at 5 years from those who did not. We identified voltage thresholds using regression techniques and then compared survival for subjects above and below the thresholds. RESULTS Cornell voltage, Cornell product, and Novacode estimate of left ventricular mass index were discriminative for mortality and had identifiable thresholds present in their relationships with mortality. Independent of systolic blood pressure, there were significant associations with 5-year mortality for Novacode index above threshold; hazard ratios were 1.58 for women and 1.27 for men, and for 5-year cardiovascular mortality were 1.78 for women and 2.34 for men. CONCLUSIONS Electrocardiographic criteria for left ventricular hypertrophy validated against mortality might be clinically useful.

Increasing colon cancer testing in rural Colorado: evaluation of the exposure to a community-based awareness campaign

PURPOSE We investigated 3 approaches for implementing the Chronic Care Model to improve diabetes care: (1) practice facilitation over 6 months using a reflective adaptive process (RAP) approach; (2) practice facilitation for up to 18 months using a continuous quality improvement (CQI) approach; and (3) providing self-directed (SD) practices with model information and resources, without facilitation. METHODS We conducted a cluster-randomized trial, called Enhancing Practice, Improving Care (EPIC), that compared these approaches among 40 small to midsized primary care practices. At baseline and 9 months and 18 months after enrollment, we assessed practice diabetes quality measures from chart audits and Practice Culture Assessment scores from clinician and staff surveys. RESULTS Although measures of the quality of diabetes care improved in all 3 groups (all P <.05), improvement was greater in CQI practices compared with both SD practices (P <.0001) and RAP practices (P <.0001); additionally, improvement was greater in SD practices compared with RAP practices (P <.05). In RAP practices, Change Culture scores showed a trend toward improvement at 9 months (P = .07) but decreased below baseline at 18 months (P <.05), while Work Culture scores decreased from 9 to 18 months (P <.05). Both scores were stable over time in SD and CQI practices. CONCLUSIONS Traditional CQI interventions are effective at improving measures of the quality of diabetes care, but may not improve practice change and work culture. Short-term practice facilitation based on RAP principles produced less improvement in quality measures than CQI or SD interventions and also did not produce sustained improvements in practice culture.

Underinsurance in Primary Care: A Report from the State Networks of Colorado Ambulatory Practices and Partners (SNOCAP)

PURPOSE Direct-to-consumer advertising (DTCA) has increased tremendously during the past decade. Recent changes in the DTCA environment may have affected its impact on clinical encounters. Our objective was to determine the rate of patient medication inquiries and their influence on clinical encounters in primary care. METHODS Our methods consisted of a cross-sectional survey in the State Networks of Colorado Ambulatory Practices and Partners, a collaboration of 3 practice-based research networks. Clinicians completed a short patient encounter form after consecutive patient encounter for one-half or 1 full day. The main outcomes were the rate of inquiries, independent predictors of inquiries, and overall impact on clinical encounters. RESULTS One hundred sixty-eight clinicians in 22 practices completed forms after 1,647 patient encounters. In 58 encounters (3.5%), the patient inquired about a specific new prescription medication. Community health center patients made fewer inquiries than private practice patients (1.7% vs 7.2%, P<.001). Predictors of inquiries included taking 3 or more chronic medications and the clinician being female. Most clinicians reported the requested medication was not their first choice for treatment (62%), but it was prescribed in 53% of the cases. Physicians interpreted the overall impact on the visit as positive in 24% of visits, neutral in 66%, and negative in 10%. CONCLUSIONS Patient requests for prescription medication were uncommon overall, and even more so among patients in lower income groups. These requests were rarely perceived by clinicians as having a negative impact on the encounter. Future mixed methods studies should explore specific socioeconomic groups and reasons for clinicians’ willingness to prescribe these medications.

Clinician burden and depression treatment: disentangling patient- and clinician-level effects of medical comorbidity.

BackgroundDespite effective prevention and early detection screening methods, colorectal cancer is the second leading cause of cancer death in the United States. Colorectal cancer screening community-based interventions are rare, and the literature lacks information about community-based intervention processes. Using participatory research methods, the High Plains Research Network developed a community-based awareness and educational intervention to increase colorectal cancer screening rates in rural northeastern Colorado. This study describes the program components and implementation and explores whether the target population was exposed to the intervention, the reach of the individual intervention components, and the effect on screening intentions.MethodsA random digit dial survey was conducted of residents age 40 and older in the first 3 communities to receive the intervention to estimate exposure to the intervention and its effect on colorectal cancer screening intentions.ResultsExposure to at least intervention component was reported by 68% of respondents (n = 460). As the level of exposure increased, intentions to talk to a doctor about colorectal cancer screening increased significantly more in respondents who had not been tested in the past 5 years than those who had (p = .025). Intentions to get tested increased significantly in both groups at the same rate as level of exposure increased (p < .001).ConclusionUsing local community members led to the successful implementation of the intervention. Program materials and messages reached a high percentage of the target population and increased colorectal cancer screening intentions.

Pragmatic Cluster Randomized Trials Using Covariate Constrained Randomization: A Method for Practice-based Research Networks (PBRNs)

Background: There has been considerable focus on the uninsured from national and state levels. There are also many Americans who have health insurance but are unable to afford their recommended care and are considered underinsured. This purpose of this study was to determine the prevalence of underinsurance among patients seen in primary care clinics. Methods: Patients in 37 primary care practices in 3 practice-based research networks completed a survey to elicit the prevalence of underinsurance among those who had insurance for a full 12 months, including private insurance, Medicare, and Medicaid. Being underinsured was based on patients reporting the delay or omission of recommended care because of their inability to afford it. Results: Of those with insurance for a full year, 36.3% were underinsured. Of those who were underinsured, 50.2% felt that their health suffered because they could not afford recommended care, a rate similar among those who were uninsured. Conclusions: When evaluating underinsurance in primary care offices, using an experiential definition based on self-reports of patients about their inability to pay for recommended health care despite having insurance, the prevalence is quite high. It is important for the primary care physician to understand that a substantial percentage of their patients may not follow through with their recommendations because of cost, despite having insurance. This also has significant implications when considering health care reform, particularly considering that these patients reported that their health suffered at a rate equal to that of the uninsured.

Testing to Prevent Colon Cancer: Results From a Rural Community Intervention

BackgroundEfforts to improve primary care depression treatment have assessed strategies across heterogeneous groups of patients, but few have examined clinician-level influences on depression treatment.ObjectiveTo examine clinician characteristics that affect depression treatment in primary care settings, using multilevel ordinal regression modeling to disentangle patient- from clinician-level effects.DesignSecondary analysis from the Quality Improvement in Depression Study dataset.ParticipantsThe participants were 1,023 primary care patients with depression who reported on treatment in the 6-month follow-up and whose clinicians (n = 158) had at least 4 patients in the study.MeasurementsPrimary outcome variable was depression treatment intensity, derived from assessment of concordance with AHCPR depression treatment guidelines based on patient-reported data on their treatment. Primary independent variable was clinical practice burden for treating depression, derived from patient- and clinician-reported composite measures tested for significant association with clinician-reported practice burden.ResultsClinicians who treat patients with more chronic medical comorbidities perceive less burden from treating depressed patients in their practice (Spearman’s rho = −.30, p < .05). Clinicians who treat patients with more chronic medical comorbidities also provide greater intensity of depression treatment (adjusted OR = 1.44, p = .02), even after adjusting for the effects of patient-level chronic medical comorbidities (adjusted OR = 0.95, p = .45).ConclusionsClinicians who provide more chronic care also provide greater depression treatment intensity, suggesting that clinicians who care for complex patients can integrate depression care into their practice. Targeting interventions to these clinicians to enhance their ability to provide guideline-concordant depression care is a worthwhile endeavor and deserves further investigation.

What Peer Mentoring Adds to Already Good Patient Care: Implementing the Carpeta Roja Peer Mentoring Program in a Well-Resourced Health Care System

Background: Cluster randomized trials (CRTs) are useful in practice-based research network translational research. However, simple or stratified randomization often yields study groups that differ on key baseline variables when the number of clusters is small. Unbalanced study arms constitute a potentially serious methodological problem for CRTs. Methods: Covariate constrained randomization with data on relevant variables before randomization was used to achieve balanced study arms in 2 pragmatic CRTs. In study 1, 16 counties in Colorado were randomized to practice-based or population-based reminder recall for vaccinating children ages 19 to 35 months. In study 2, 18 primary care practices were randomized to computer decision support plus practice facilitation versus computer decision support alone to improve care for patients with stage 3 and 4 chronic kidney disease. For each study, a set of optimal randomizations, which minimized differences of key variables between study arms, was identified from the set of all possible randomizations. Results: Differences between study arms were smaller in the optimal versus remaining randomizations. Even for the randomization in the optimal set with the largest difference between groups, study arms did not differ significantly on any variable for either study (P > .05). Conclusions: Covariate constrained randomization, which restricts the full randomization set to a subset in which differences between study arms are minimized, is a useful tool for achieving balanced study arms in CRTs. Because of the increasing recognition of the risk of imbalance in CRTs and implications for interpreting study findings, procedures of this type should be considered in designing practice-based or community-based trials.
