Declining Use of Primary Care Among Commercially Insured Adults in the United States, 2008-2016

BACKGROUND

Primary care is known to improve outcomes and lower health care costs, prompting recent U.S. policy efforts to expand its role. Nonetheless, there is early evidence of a decline in per capita primary care visit rates, and little is understood about what is contributing to the decline.

OBJECTIVE

To describe primary care provider (PCP) visit trends among adults enrolled with a large, national, commercial insurer and assess factors underlying a potential decline in PCP visits.

DESIGN

Descriptive repeated cross-sectional study using 100% deidentified claims data from the insurer, 2008-2016. A 5% claims sample was used for Poisson regression models to quantify visit trends.

SETTING

National, population-based.

PARTICIPANTS

Adult health plan members aged 18 to 64 years.

MEASUREMENTS

PCP visit rates per 100 member-years.

RESULTS

In total, 142 million primary care visits among 94 million member-years were examined. Visits to PCPs declined by 24.2%, from 169.5 to 134.3 visits per 100 member-years, while the proportion of adults with no PCP visits in a given year rose from 38.1% to 46.4%. Rates of visits addressing low-acuity conditions decreased by 47.7% (95% CI, -48.1% to -47.3%). The decline was largest among the youngest adults (-27.6% [CI, -28.2% to -27.1%]), those without chronic conditions (-26.4% [CI, -26.7% to -26.1%]), and those living in the lowest-income areas (-31.4% [CI, -31.8% to -30.9%]). Out-of-pocket cost per problem-based visit rose by $9.4 (31.5%). Visit rates to specialists remained stable (-0.08% [CI, -0.56% to 0.40%]), and visits to alternative venues, such as urgent care clinics, increased by 46.9% (CI, 45.8% to 48.1%).

LIMITATION

Data were limited to a single commercial insurer and did not capture nonbilled clinician-patient interactions.

CONCLUSION

Commercially insured adults have been visiting PCPs less often, and nearly one half had no PCP visits in a given year by 2016. Our results suggest that this decline may be explained by decreased real or perceived visit needs, financial deterrents, and use of alternative sources of care.

Validation of use of billing codes for identifying telemedicine encounters in administrative data

Background

Telemedicine is the use of telecommunication technology to remotely provide healthcare services. Evaluation of telemedicine use often relies on administrative data, but the validity of identifying telemedicine encounters in administrative data is not known. The objective of this study was to assess the accuracy of billing codes for identifying telemedicine use.

Methods

In this retrospective study of encounters within a large integrated health system from January 2016 to December 2017, we examined the accuracy of billing codes for identifying live-interactive and store-and-forward telemedicine encounters compared to manual chart review. To further examine external validity, we applied these codes and assessed patient and visit characteristics for identified live-interactive telemedicine encounters and store-and-forward telemedicine encounters in a second data set.

Results

In manual review of 390 encounters, 75 encounters were live-interactive telemedicine and 158 were store-and-forward telemedicine. In weighted analysis, the presence of the GT modifier in the absence of the GQ modifier or CPT code 99444 yielded 100% sensitivity and 99.99% specificity for identification of live-interactive telemedicine encounters. The presence of either the GQ modifier or the CPT code 99444 had 100% sensitivity and 100% specificity for identification of store-and-forward telemedicine encounters. Applying these algorithms to a second data set (n = 5,917,555) identified telemedicine encounters with expected patient and visit characteristics.

Conclusions

These findings provide support for use of CPT codes to perform telemedicine research in administrative data, aiding ongoing work to understand the role of non-face-to-face care in optimizing health care delivery.

Unscheduled Referrals and Unattended Appointments After Pediatric Subspecialty Referral

OBJECTIVES

Incomplete subspecialty referrals, whether unscheduled or unattended, represent unmet patient needs and an opportunity to improve patient safety and experiences. Our objectives were to describe the rates of appointment scheduling and visit attendance after pediatric subspecialty referral and to examine patient and systems factors associated with scheduled referrals and attended appointments.

METHODS

We conducted a retrospective review of referrals within a network of 52 primary and urgent care sites from November 2016 to October 2017. We included referrals for children ≤17 years old referred to medical or surgical subspecialists. We examined patient and health systems factors associated with (1) appointment scheduling and (2) visit attendance.

RESULTS

Of 20 466 referrals, 13 261 (65%) resulted in an appointment scheduled within 90 days and 10 514 (51%) resulted in a visit attended within 90 days. In adjusted analyses, referral to surgical subspecialists was associated with an increased likelihood of appointment scheduling but a decreased likelihood of visit attendance. Compared with appointments scheduled within 7 days, appointments with intervals from referral to scheduled appointment exceeding 7 days were associated with decreasing likelihood of visit attendance (adjusted odds ratio 8-14 days 0.48; 95% confidence interval 0.37-0.61). Patient factors associated with decreased likelihood of both appointment scheduling and visit attendance included African American race, public insurance, and lower zip code median income.

CONCLUSIONS

Patient and system factors were associated with variation in appointment scheduling and visit attendance. Decreased interval to appointment was significantly associated with visit attendance. These factors represent targets for interventions to improve referral completion.

National Trends in Primary Care Visit Use and Practice Capabilities, 2008-2015

PURPOSE

Recent evidence shows a national decline in primary care visit rates over the last decade. It is unclear how changes in practice-including the use and content of primary care visits-may have contributed.

METHODS

We analyzed nationally representative data of adult visits to primary care physicians (PCPs) and physician practice characteristics from 2007-2016 (National Ambulatory Medical Care Survey). United States census estimates were used to calculate visits per capita. Measures included visit rates per person year; visit duration; number of medications, diagnoses, and preventive services per visit; percentage of visits with scheduled follow-up; and percentage of physicians with practice capabilities including an electronic medical record (EMR).

RESULTS

Our weighted sample represented 3.2 billion visits (83,368 visits, unweighted). Visits per capita declined by 20% (-0.25 visits per person, 95% CI, -0.32 to -0.19) during this time, while visit duration increased by 2.4 minutes per visit (95% CI, 1.1-3.8). Per visit, PCPs addressed 0.30 more diagnoses (95% CI, 0.16-0.43) and 0.82 more medications (95% CI, 0.59-1.1), and provided 0.24 more preventive services (95% CI, 0.12-0.36). Visits with scheduled PCP followup declined by 6.0% (95% CI, -12.4 to 0.46), while PCPs reporting use of EMR increased by 44.3% (95% CI, 39.1-49.5) and those reporting use of secure messaging increased by 60.9% (95% CI, 27.5-94.3).

CONCLUSION

From 2008 to 2015, primary care visits were longer, addressed more issues per visit, and were less likely to have scheduled follow-up for certain patients and conditions. Meanwhile, more PCPs offered non-face-to-face care. The decline in primary care visit rates may be explained in part by PCPs offering more comprehensive in-person visits and using more non-face-to-face care.

Use of Commercial Direct-to-Consumer Telemedicine by Children

OBJECTIVE

In commercial direct-to-consumer (DTC) telemedicine, physicians outside of the medical home treat common, acute complaints through real-time, audio-visual conferencing using telephones and personal computers. There has been little examination of the use of DTC telemedicine by children. We describe trends in DTC telemedicine use and DTC telemedicine visit characteristics.

METHODS

Using 2011-2016 claims from a large national health plan, we identified pediatric acute visits to DTC telemedicine and to primary care providers (PCPs). We examined DTC telemedicine visit trends and compared DTC telemedicine and acute PCP visit diagnoses and patient characteristics.

RESULTS

From 2011 through 2016, pediatric DTC telemedicine visits increased from 38 to 24,409 visits annually. In 2015 and 2016, the most common primary diagnoses for DTC telemedicine visits (n = 42,072) were infections of the nose/sinuses (24%), mouth/throat (16%), and ear (9%), which were also the most common diagnoses for acute PCP visits (n = 6,917,976). Odds of DTC telemedicine use were higher for children in non-metropolitan communities (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.40-1.51) and children without preventive visits (OR, 1.08; 95% CI, 1.06-1.11). Compared to children receiving acute PCP care, children with DTC telemedicine visits were also more likely to have had urgent care (17% vs 10%; P < .001) and emergency department visits (21% vs 19%; P < .001) during the study period.

CONCLUSIONS

The use of commercial DTC telemedicine visits for children is growing rapidly, primarily for acute respiratory infections. Compared to children who did not use DTC telemedicine for acute care, children using DTC telemedicine were also more likely to use other venues for acute care outside of the medical home.

Quality Of Care For Acute Respiratory Infections During Direct-To-Consumer Telemedicine Visits For Adults

In direct-to-consumer telemedicine, physicians treat patients through real-time audiovisual conferencing for common conditions such as acute respiratory infections. Early studies had mixed findings on the quality of care provided during direct-to-consumer telemedicine and were limited by small sample sizes and narrow geographic scopes. Using claims data for 2015-16 from a large national commercial insurer, we examined the quality of antibiotic management in adults with acute respiratory infection diagnoses at 38,839 direct-to-consumer telemedicine visits, compared to the quality at 942,613 matched primary care visits and 186,016 matched urgent care visits. In the matched analyses, we found clinically similar rates of antibiotic use, broad-spectrum antibiotic use, and guideline-concordant antibiotic management. However, direct-to-consumer telemedicine visits had less appropriate streptococcal testing and a higher frequency of follow-up visits. These results suggest specific opportunities for improvement in direct-to-consumer telemedicine quality.

Antibiotic Prescribing During Pediatric Direct-to-Consumer Telemedicine Visits

BACKGROUND AND OBJECTIVES

Use of commercial direct-to-consumer (DTC) telemedicine outside of the pediatric medical home is increasing among children, and acute respiratory infections (ARIs) are the most commonly diagnosed condition at DTC telemedicine visits. Our objective was to compare the quality of antibiotic prescribing for ARIs among children across 3 settings: DTC telemedicine, urgent care, and the primary care provider (PCP) office.

METHODS

In a retrospective cohort study using 2015-2016 claims data from a large national commercial health plan, we identified ARI visits by children (0-17 years old), excluding visits with comorbidities that could affect antibiotic decisions. Visits were matched on age, sex, chronic medical complexity, state, rurality, health plan type, and ARI diagnosis category. Within the matched sample, we compared the percentage of ARI visits with any antibiotic prescribing and the percentage of ARI visits with guideline-concordant antibiotic management.

RESULTS

There were 4604 DTC telemedicine, 38 408 urgent care, and 485 201 PCP visits for ARIs in the matched sample. Antibiotic prescribing was higher for DTC telemedicine visits than for other settings (52% of DTC telemedicine visits versus 42% urgent care and 31% PCP visits; P < .001 for both comparisons). Guideline-concordant antibiotic management was lower at DTC telemedicine visits than at other settings (59% of DTC telemedicine visits versus 67% urgent care and 78% PCP visits; P < .001 for both comparisons).

CONCLUSIONS

At DTC telemedicine visits, children with ARIs were more likely to receive antibiotics and less likely to receive guideline-concordant antibiotic management compared to children at PCP visits and urgent care visits.

Parent Empowerment in Pediatric Healthcare Settings: A Systematic Review of Observational Studies

BACKGROUND

Parent empowerment is often an expressed goal in clinical pediatrics and in pediatric research, but the antecedents and consequences of parent empowerment are not well established.

OBJECTIVE

The objective of this systematic review was to synthesize potential antecedents and consequences of parent empowerment in healthcare settings.

ELIGIBILITY CRITERIA

The inclusion criteria were (1) studies with results about parent empowerment in the context of children's healthcare or healthcare providers; and (2) qualitative studies, observational studies, and systematic reviews of such studies.

INFORMATION SOURCES

We searched the databases of PubMed, Web of Science, and Google Scholar (2006-2017) and reference lists.

INCLUDED STUDIES

Forty-four articles met the inclusion criteria.

SYNTHESIS OF RESULTS

We identified six themes within consequences of empowerment: increased parent involvement in daily care, improved symptom management, enhanced informational needs and tools, increased involvement in care decisions, increased advocacy for child, and engagement in empowering others. Six themes summarizing antecedents of empowerment also emerged: parent-provider relationships, processes of care, experiences with medical care, experiences with community services, receiving informational/emotional support, and building personal capacity and narrative. We synthesized these findings into a conceptual model to guide future intervention development and evaluation.

STRENGTHS AND LIMITATIONS OF EVIDENCE

Non-English articles were excluded.

INTERPRETATION

Parent empowerment may enhance parent involvement in daily care and care decisions, improve child symptoms, enhance informational needs and skills, and increase advocacy and altruistic behaviors. Parent empowerment may be promoted by the parent-provider relationship and care processes, finding the right fit of medical and community services, and attention to the cognitive and emotional needs of parents.

Geographic Access to International Board-Certified Lactation Consultants in Pennsylvania

BACKGROUND:

Availability of professional lactation support has been associated with increased breastfeeding rates; however, data about access to international board-certified lactation consultants are limited.

RESEARCH AIMS:

The aims were (a) to assess geographic access to international board-certified lactation consultants in Pennsylvania, (b) to compare access in rural/urban counties, and (c) to compare access by county-level breastfeeding initiation rates.

METHODS:

Using geographic information systems methodology and a cross-sectional observational design, we calculated the proportion of young children living within 15, 30, and 60 miles of international board-certified lactation consultants in Pennsylvania. We calculated these proportions for all children in Pennsylvania, for children in urban and rural counties, and for children in counties with low, medium, and high breastfeeding initiation rates. Comparisons were done to answer the research aims.

RESULTS:

Over 90% of young children live within 30 miles of an international board-certified lactation consultant. Compared to children in urban counties, fewer children in rural counties live within 15 and 30 miles of these providers. In counties with high breastfeeding initiation rates, a larger percentage of children live within 15 miles of an international board-certified lactation consultant than in counties with low breastfeeding initiation rates.

CONCLUSION:

While most Pennsylvania children live in proximity of an international board-certified lactation consultant, this was true for a lower percentage of children in rural counties and in counties with lower breastfeeding rates.

Referring Hospital Characteristics Associated With Potentially Avoidable Emergency Department Transfers

OBJECTIVE

Many emergency department (ED) transfers of children may be avoidable. Identifying hospital-level variables associated with avoidable transfers may guide system-level interventions to improve pediatric emergency care. We sought to examine hospital characteristics associated with ED transfers deemed "probably avoidable" in a large state Medicaid program.

METHODS

We performed a retrospective cohort study using 2009 to 2013 claims data for Pennsylvania Medicaid beneficiaries. We categorized all ED transfers of children < 17 years old as "probably avoidable," "possibly avoidable", or "unavoidable" based on ultimate disposition and procedures (including subspecialty consultations) at the receiving ED. Using descriptive statistics and multivariable regression, we examined hospital characteristics associated with probably avoidable transfers.

RESULTS

Among 2,839,379 pediatric visits to EDs across 158 Pennsylvania hospitals, 20,304 resulted in transfer. Among these, 3,764 (18.5%) were categorized as probably avoidable and 6,091 (30.0%) as possibly avoidable transfers. In adjusted analysis, compared to hospitals with no pediatric-specific capabilities, probably avoidable transfers were less likely from referring hospitals with pediatric-specific EDs and no other pediatric-specific capabilities (adjusted odds ratio [aOR] = 0.38, 95% confidence interval [CI] = 0.21-0.71) and from referring hospitals with pediatric-specific EDs and inpatient capabilities (aOR = 0.36, 95% CI = 0.20-0.64). Probably avoidable transfers were more likely from referring hospitals in large metropolitan areas (aOR = 2.64, 95% CI = 1.46-4.80) compared to those in rural areas.

CONCLUSIONS

Among pediatric emergency transfers in a large state Medicaid program with a nearly 20% probably avoidable transfer rate, there was significant hospital-level variation in the proportion of probably avoidable transfers. Transfers from hospitals in large metropolitan areas and transfers from hospitals without pediatric-specific capabilities had increased odds of being probably avoidable transfers, such that these hospitals may represent targets for interventions to reduce these transfers.

System-Level Factors Associated With Use of Outpatient Specialty Palliative Care Among Patients With Advanced Cancer

PURPOSE

The proportion of patients with advanced cancer who receive outpatient specialty palliative care (OSPC) is as low as 2.0%. Improved understanding of the system-level factors influencing use of OSPC could inform adaptations to the delivery of palliative care to maximize access. We examined associations between OSPC use among patients with advanced solid tumors and oncology-OSPC clinic colocation and patient travel time to an OSPC clinic.

PATIENTS AND METHODS

We conducted a retrospective cohort study of patients with advanced solid tumors receiving oncologic treatment between January 1 and December 31, 2016, within a comprehensive cancer center network with well-established, oncology-specific OSPC clinics. Multivariable logistic regression analysis was used to evaluate the associations of clinic colocation and geographic access with OSPC use.

RESULTS

Of 9,485 patients with advanced solid tumors, 478 (5.0%) received OSPC services in 2016. After controlling for age, sex, marital status, cancer type, insurance, treatment intent, and illness severity, patients whose oncologist practices were colocated with OSPC clinics were more likely to use OSPC (odds ratio [OR], 19.2; 95% CI, 14.1 to 26.2). Compared with patients who lived > 90 minutes from an OSPC clinic, patients with travel times of < 30 minutes (OR, 3.2; 95% CI, 2.2 to 4.6) and 31 to 60 minutes (OR, 2.4; 95% CI, 1.6 to 3.6) were also more likely to use OSPC.

CONCLUSION

Among patients with advanced solid tumors, colocation of oncology and OSPC clinics and shorter patient travel time were associated with greater odds of using OSPC. Future efforts to increase OSPC use in this population should consider clinic colocation and travel burden.

Telelactation via Mobile App: Perspectives of Rural Mothers, Their Care Providers, and Lactation Consultants

Background: Rural-urban disparities exist in breastfeeding rates and availability of lactation support. Direct-to-consumer (DTC) telelactation that uses two-way video through personal devices has the potential to increase access to international board-certified lactation consultants (IBCLCs) in rural settings that lack them. This study describes the feasibility and acceptability of DTC telelactation for rural mothers. Methods: We conducted semi-structured interviews among various stakeholders involved in a study exploring the impact of telelactation through mobile phone app in rural Pennsylvania. Interviewees included mother participants assigned to receive telelactation (n = 17), IBCLCs employed by the telelactation vendor (n = 7), and nurses (n = 2) and physicians (n = 1) caring for mother participants at the recruitment hospital. Thematic content analysis was used to analyze qualitative data. Results: Interviewees reported that telelactation was convenient and efficient, provided a needed service in rural areas lacking breastfeeding support services, and increased maternal breastfeeding confidence. Telelactation was noted to have several advantages over in-person and telephone-based support. Barriers to use included maternal reluctance to conduct video calls with an unknown provider, preference for community-based breastfeeding resources, and technical issues including limited WiFi in rural areas. Conclusions: Among rural women who experience inequitable access to qualified breastfeeding support resources, DTC telelactation appears to be an acceptable delivery model for lactation assistance.

Primary Care Practitioners' Perceptions of Electronic Consult Systems: A Qualitative Analysis

IMPORTANCE

Safety-net health systems across the country are implementing electronic consult (eConsult) systems in which primary care practitioners (PCPs) submit all requests for specialty assistance electronically to be reviewed and discussed with specialists. Evidence suggests that eConsult systems can make significant improvements in specialty access, but the outcomes of these systems for frontline PCPs is poorly understood.

OBJECTIVE

To understand PCP perceptions of the results of eConsult initiation on PCP workflow, specialist access, and patient care.

DESIGN, SETTING, AND PARTICIPANTS

Qualitative interviews were conducted from December 1, 2016, to April 15, 2017, with 40 safety-net PCPs in Los Angeles County who use the Los Angeles County Department of Health Services (DHS) eConsult system. Interviewees were recruited to include diversity in PCP type, practice setting, and employer (DHS employed vs DHS affiliated). Participants were interviewed about their perceptions of clinical workflow, access to specialists, relationships with specialists, and referral decision making.

MAIN OUTCOMES AND MEASURES

Perceptions of the results of eConsult, including positive and negative themes and remaining perceived gaps in specialty care.

RESULTS

Of the 40 participants, 27 (68%) were women; 24 (60%) PCPs performed 5 or more eConsults per week. Primary care practitioners' perceptions of eConsult clustered around 4 main themes: access and timeliness of specialty care, shift of work to PCPs, relationships with specialists, and eConsult interface issues. Many PCPs praised the improved timeliness of specialist input with eConsult, as well as the added clinical and educational value of dialogue with specialists, particularly compared with the limitations of the prior referral process. However, PCPs also consistently perceived that eConsult shifted some of the work of specialty care to them. Many PCPs believed that this extra burden was worth the effort given the benefits of eConsult, such as improved timeliness of care and ability to manage specialty conditions. In contrast, others were frustrated by the increased administrative burden, broadened clinical responsibility, and restructuring of specialty care delivery.

CONCLUSIONS AND RELEVANCE

While associated with improved specialty care access, eConsult systems simultaneously created new challenges for PCPs, such as an increased burden of work in providing specialty care. Primary care practitioners varied in their enthusiasm for these workflow changes with diverging perceptions of the same processes. Our findings provide insights on challenges future primary care transformation efforts may face.

Transportation characteristics associated with non-arrivals to paediatric clinic appointments: a retrospective analysis of 51 580 scheduled visits

BACKGROUND

Prior work has not studied the effects of transportation accessibility and patient factors on clinic non-arrival.

OBJECTIVES

Our objectives were: (1) to evaluate transportation characteristics and patient factors associated with clinic non-arrival, (2) to evaluate the comparability of bus and car drive time estimates, and (3) to evaluate the combined effects of transportation accessibility and income on scheduled appointment non-arrival.

METHODS

We queried electronic administrative records at an urban general pediatrics clinic. We compared patient and transportation characteristics between arrivals and non-arrivals for scheduled appointments using multivariable modeling.

RESULTS

There were 15 346 (29.8%) clinic non-arrivals. In separate car and bus multivariable models that controlled for patient and transit characteristics, we identified significant interactions between income and drive time, and clinic non-arrival. Patients in the lowest quartile of income who were also in the longest quartile of travel time by bus had an increased OR of clinic non-arrival compared with patients in the lowest quartile of income and shortest quartile of travel time by bus (1.55; P<0.01). Similarly, patients in the lowest quartile of income who were also in the longest quartile of travel time by car had an increased OR of clinic non-arrival compared with patients in the lowest quartile of income and shortest quartile of travel time by car (1.21, respectively; P<0.01).

CONCLUSIONS

Clinic non-arrival is associated with the interaction of longer travel time and lower income.

Access to High Pediatric-Readiness Emergency Care in the United States

OBJECTIVE

To determine the geographic accessibility of emergency departments (EDs) with high pediatric readiness by assessing the percentage of US children living within a 30-minute drive time of an ED with high pediatric readiness, as defined by collaboratively developed published guidelines.

STUDY DESIGN

In this cross-sectional analysis, we examined geographic access to an ED with high pediatric readiness among US children. Pediatric readiness was assessed using the weighted pediatric readiness score (WPRS) of US hospitals based on the 2013 National Pediatric Readiness Project (NPRP) survey. A WPRS of 100 indicates that the ED meets the essential guidelines for pediatric readiness. Using estimated drive time from ZIP code centroids, we determined the proportions of US children living within a 30-minute drive time of an ED with a WPRS of 100 (maximum), 94.3 (90th percentile), and 83.6 (75th percentile).

RESULTS

Although 93.7% of children could travel to any ED within 30 minutes, only 33.7% of children could travel to an ED with a WPRS of 100, 55.3% could travel to an ED with a WPRS at or above the 90th percentile, and 70.2% could travel to an ED with a WPRS at or above the 75th percentile. Among children within a 30-minute drive of an ED with the maximum WPRS, 90.9% lived closer to at least 1 alternative ED with a WPRS below the maximum. Access varied across census divisions, ranging from 14.9% of children in the East South Center to 56.2% in the Mid-Atlantic for EDs scoring a maximum WPRS.

CONCLUSION

A significant proportion of US children do not have timely access to EDs with high pediatric readiness.

Impact of Implementation of Electronically Transmitted Referrals on Pediatric Subspecialty Visit Attendance

OBJECTIVE

One barrier to timely access to outpatient pediatric subspecialty care is the complexity of scheduling processes. We evaluated the impact of implementing electronically transmitted referrals on subspecialty visit attendance.

METHODS

Through collaboration with stakeholders, an electronically transmitted referral order system was designed, piloted, and implemented in 15 general pediatrics practices, with 24 additional practices serving as controls. We used statistical process control methods and difference-in-differences analysis to examine visits attended, appointments scheduled, appointment nonattendance, and referral volume. Electronically transmitted referrals then were expanded to all 39 practices. We surveyed referring pediatricians at all practices before and after implementation.

RESULTS

From April 2015 through September 2016 there were 33,485 referral orders across all practices (7770 before the pilot, 11,776 during the pilot, 13,939 after full implementation). At pilot practices, there was a significant and sustained improvement in subspecialty visits attended within 4 weeks of referral (10.9% to 20.0%; P < .001). Relative to control practices, pilot practices experienced an 8.6% improvement (P = .001). After implementation at control practices, rates of visits attended also improved but to a smaller degree: 11.8% to 14.7% (P < .001). In survey responses, referring pediatricians noted improved scheduling processes but had continued concerns with appointment availability and referral tracking.

CONCLUSIONS

While electronically transmitted referrals improved visit attendance after pediatric subspecialty referral, the sizable percentage of children without attended visits, the muted effect at control practices, and pediatrician survey responses indicate that additional work is needed to address barriers to pediatric subspecialty care.

Trends in Visits to Specialist Physicians Involving Nurse Practitioners and Physician Assistants, 2001 to 2013

This study describes the roles of nurse practitioners and physician assistants in providing care to specialist physicians’ patients.

Strengthening stakeholder-engaged research and research on stakeholder engagement

Stakeholder engagement is an emerging field with little evidence to inform best practices. Guidelines are needed to improve the quality of research on stakeholder engagement through more intentional planning, evaluation and reporting. We developed a preliminary framework for planning, evaluating and reporting stakeholder engagement, informed by published conceptual models and recommendations and then refined through our own stakeholder engagement experience. Our proposed exploratory framework highlights contexts and processes to be addressed in planning stakeholder engagement, and potential immediate, intermediate and long-term outcomes that warrant evaluation. We use this framework to illustrate both the minimum information needed for reporting stakeholder-engaged research and the comprehensive detail needed for reporting research on stakeholder engagement.

Family Perspectives on Telemedicine for Pediatric Subspecialty Care

BACKGROUND

Children often have difficulty accessing subspecialty care, and telemedicine may improve access to subspecialty care, but information is lacking on how best to implement telemedicine programs to maximize acceptance and, ultimately, maximize impact for patients and their families.

METHODS AND MATERIALS

To understand how subspecialty telemedicine is perceived and to identify design elements with the potential to improve telemedicine uptake and impact, we conducted and analyzed semi-structured interviews with 21 informants, including parents and caregivers of children with subspecialty care needs and adolescent and young adult patients with subspecialty care needs.

RESULTS

Although informants saw the potential value of using telemedicine to replace in-person subspecialty visits, they were more enthusiastic about using telemedicine to complement rather than replace in-person visits. For example, they described the potential to use telemedicine to facilitate previsit triage encounters to assess whether the patient was being scheduled with the correct subspecialist and with the appropriate level of urgency. They also felt that telemedicine would be useful for communication with subspecialists after scheduled in-person visits for follow-up questions, care coordination, and to discuss changes in health status. Informants felt that it was important for telemedicine programs to have transparent and reliable scheduling, same-day scheduling options, continuity of care with trusted providers, clear guidelines on when to use telemedicine, and preservation of parent choice regarding method of care delivery.

CONCLUSIONS

Parents and patients articulated preferences regarding pediatric subspecialty telemedicine in this qualitative, hypothesis-generating study. Understanding and responding to patient and caregiver perceptions and preferences will be crucial to ensure that telemedicine drives true innovation in care delivery rather than simply recapitulating prior models of care.

Use of Adult-Trained Medical Subspecialists by Children Seeking Medical Subspecialty Care

OBJECTIVES

To quantify the use of adult-trained medical subspecialists by children and to determine the association between geographic access to pediatric subspecialty care and the use of adult-trained subspecialists. Children with limited access to pediatric subspecialty care may seek care from adult-trained subspecialists, but data on this practice are limited.

STUDY DESIGN

We identified children aged <16 years in 2007-2012 Pennsylvania Medicaid claims. We categorized outpatient visits to 9 selected medical subspecialties as either pediatric or adult-trained subspecialty visits. We used multinomial logistic regression to examine the adjusted association between travel times to pediatric referral centers and use of pediatric vs adult-trained medical subspecialists for children with and without complex chronic conditions (CCCs).

RESULTS

Among 1.1 million children, 8% visited the examined medical subspecialists, with 10% of these children using adult-trained medical subspecialists. Compared with children with a ≤30-minute travel time to a pediatric referral center, children with a >90-minute travel time were more likely to use adult-trained subspecialists (without CCCs: relative risk ratio [RRR], 1.94, 95% CI, 1.79-2.11; with CCCs: RRR, 2.33; 95% CI, 2.10-2.59) and less likely to use pediatric subspecialists (without CCCs: RRR, 0.66; 95% CI, 0.63-0.68; with CCCs: RRR, 0.76, 95% CI, 0.73-0.79).

CONCLUSION

Among medical subspecialty fields with pediatric and adult-trained subspecialists, adult-trained subspecialists provided 10% of care to children overall and 18% of care to children living >90 minutes from pediatric referral centers. Future studies should examine consequences of adult-trained medical subspecialist use on pediatric health outcomes and identify strategies to increase access to pediatric subspecialists.

Family Perspectives on High-Quality Pediatric Subspecialty Referrals

OBJECTIVE

Although children are frequently referred to subspecialist physicians, many inadequacies in referral processes have been identified from physician and system perspectives. Little is known, however, about how to comprehensively measure or improve the quality of the referral systems from a family-centered perspective. To foster family-centered improvements to pediatric subspecialty referrals, we sought to develop a framework for high-quality, patient-centered referrals from the perspectives of patients and their families.

METHODS

We used stakeholder-informed qualitative analysis of parent, caregiver, and patient interviews to identify outcomes, processes, and structures of high-quality pediatric subspecialty referrals as perceived by patients and their family members.

RESULTS

We interviewed 21 informants. Informants identified 5 desired outcomes of subspecialty referrals: improved functional status or symptoms; improved long-term outcomes; improved knowledge of their disease; informed expectations; and reduced anxiety about the child's health status. Processes that informants identified as supporting these outcomes centered around 6 key steps in subspecialty referrals, including the referral decision, previsit information transfer, appointment scheduling, subspecialist visit, postvisit information transfer, and ongoing care integration and communication. Health care delivery structures identified by informants as supporting these processes included physical infrastructure, human resources, and information technology systems.

CONCLUSIONS

We identified family-centered outcomes, processes, and structures of high-quality pediatric subspecialty referrals. These domains can be used not only to improve measurement of the quality of existing referral systems but also to inform future interventions to improve patient-centered outcomes for children in need of specialty care.

Opportunity costs of ambulatory medical care in the United States

OBJECTIVES

The typical focus in discussions of healthcare spending is on direct medical costs such as physician reimbursement. The indirect costs of healthcare-patient opportunity costs associated with seeking care, for example-have not been adequately quantified. We aimed to quantify the opportunity costs for adults seeking medical care for themselves or others.

STUDY DESIGN

Secondary analysis of the 2003-2010 American Time Use Survey (ATUS).

METHODS

We used the nationally representative 2003-2010 ATUS to estimate opportunity costs associated with ambulatory medical visits. We estimated opportunity costs for employed adults using self-reported hourly wages and for unemployed adults using a Heckman selection model. We used the Medical Expenditure Panel Survey to compare opportunity costs with direct costs (ie, patient out-of-pocket, provider reimbursement) in 2010.

RESULTS

Average total time per visit was 121 minutes (95% CI, 118-124), with 37 minutes (95% CI, 36-39) of travel time and 84 minutes (95% CI, 81-86) of clinic time. The average opportunity cost per visit was $43, which exceeds the average patient's out-of-pocket payment. Total opportunity costs per year for all physician visits in the United States were $52 billion in 2010. For every dollar spent in visit reimbursement, an additional 15 cents were spent in opportunity costs.

CONCLUSIONS

In the United States, opportunity costs associated with ambulatory medical care are substantial. Accounting for patient opportunity costs is important for examining US healthcare system efficiency and for evaluating methods to improve the efficient delivery of patient-centered care.

Optimizing Telehealth Strategies for Subspecialty Care: Recommendations from Rural Pediatricians

BACKGROUND

Telehealth offers strategies to improve access to subspecialty care for children in rural communities. Rural pediatrician experiences and preferences regarding the use of these telehealth strategies for children's subspecialty care needs are not known. We elicited rural pediatrician experiences and preferences regarding different pediatric subspecialty telehealth strategies.

MATERIALS AND METHODS

Seventeen semistructured telephone interviews were conducted with rural pediatricians from 17 states within the United States. Interviewees were recruited by e-mails to a pediatric rural health listserv and to rural pediatricians identified through snowball sampling. Themes were identified through thematic analysis of interview transcripts. Institutional Review Board approval was obtained.

RESULTS

Rural pediatricians identified several telehealth strategies to improve access to subspecialty care, including physician access hotlines, remote electronic medical record access, electronic messaging systems, live video telemedicine, and telehealth triage systems. Rural pediatricians provided recommendations for optimizing the utility of each of these strategies based on their experiences with different systems. Rural pediatricians preferred specific telehealth strategies for specific clinical contexts, resulting in a proposed framework describing the complementary role of different telehealth strategies for pediatric subspecialty care. Finally, rural pediatricians identified additional benefits associated with the use of telehealth strategies and described a desire for telehealth systems that enhanced (rather than replaced) personal relationships between rural pediatricians and subspecialists.

CONCLUSIONS

Rural pediatricians described complementary roles for different subspecialty care telehealth strategies. Additionally, rural pediatricians provided recommendations for optimizing individual telehealth strategies. Input from rural pediatricians will be crucial for optimizing specific telehealth strategies and designing effective telehealth systems.

The opportunity costs of informal elder-care in the United States: new estimates from the American Time Use Survey

OBJECTIVES

To provide nationally representative estimates of the opportunity costs of informal elder-care in the United States.

DATA SOURCES

Data from the 2011 and 2012 American Time Use Survey.

STUDY DESIGN

Wage is used as the measure of an individual's value of time (opportunity cost), with wages being imputed for nonworking individuals using a selection-corrected regression methodology.

PRINCIPAL FINDINGS

The total opportunity costs of informal elder-care amount to $522 billion annually, while the costs of replacing this care by unskilled and skilled paid care are $221 billion and $642 billion, respectively.

CONCLUSIONS

Informal caregiving remains a significant phenomenon in the United States with a high opportunity cost, although it remains more economical (in the aggregate) than skilled paid care.

Supply and utilization of pediatric subspecialists in the United States

OBJECTIVE

The wide geographic variation in pediatric subspecialty supply in the United States has been a source of concern. Whether children in areas with decreased supply receive less subspecialty care or have worse outcomes has not been adequately evaluated. Among children with special health care needs, we examined the association between pediatric subspecialty supply and subspecialty utilization, need, child disease burden, and family disease burden.

METHODS

We measured pediatric subspecialist supply as pediatric subspecialists per capita in each residential county. By using the 2009-2010 National Survey of Children With Special Health Care Needs and controlling for many potential confounders, we examined the association between quintile of pediatric subspecialty supply and parent-reported subspecialty utilization, perceived subspecialty need, and child and family disease burden.

RESULTS

County-level pediatric subspecialty supply ranged from a median of 0 (lowest quintile) to 59 (highest quintile) per 100 000 children. In adjusted results, compared with children in the highest quintile, children in the lowest quintile of supply were 4.8% less likely to report ambulatory subspecialty visits (P < .001), 5.3% less likely to perceive subspecialty care needs (P < .001), and 2.3% more likely to report emergency department visits (P = .018). There were no meaningful differences between pediatric subspecialty supply quintiles for other measures of child or family disease burden.

CONCLUSIONS

Children living in counties with the lowest supply of pediatric subspecialists had both decreased perceived need for subspecialty care and decreased utilization of subspecialists. However, the differences in supply were not associated with meaningful differences in child or family disease burden.

Hospitalization of early preterm, late preterm, and term infants during the first year of life by gestational age

OBJECTIVES

The goal of this study was to describe hospitalizations of infants during the first year of life according to week of gestational age (GA). We hypothesized that odds of any hospitalization would generally decrease with increasing GA, with late preterm infants experiencing additional increased risk of specific hospitalizations, such as hyperbilirubinemia.

METHODS

Birth certificates for > 6.6 million infants born in California hospitals between 1993 and 2005 and surviving to discharge were linked to hospital discharge records during the first year of life. Odds of any hospitalization and any hospitalization for specific diagnoses during the first year of life were determined for infants 23 to 44 weeks' GA. Further analysis determined odds of any hospitalization within 14, 30, and 90 days of birth discharge, and observed odds were compared with expected odds obtained through quadratic modeling.

RESULTS

Odds of any hospitalization within the first year of life decreased with advancing GA, but observed odds of any hospitalization exceeded expected odds for 35-, 36-, and 37-week GA infants for all time periods after discharge. Odds of any hospitalization for hyperbilirubinemia were greatest for infants 33 to 38 weeks' GA (peak odds ratio at 36 weeks' GA: 2.86 [95% confidence interval: 2.73-3.00]), and a relative peak in odds of any hospitalization for specific infections was observed among infants 33 to 36 weeks' GA.

CONCLUSIONS

Odds of any hospitalization during the first year of life exceeded expected odds of hospitalization for 35-, 36-, and 37-week GA infants. GAs at risk overlapped with, but were not identical to, GAs identified as late preterm infants.

Hospitalization of rural and urban infants during the first year of life

OBJECTIVES

To examine hospitalizations and length of stay (LOS) for infants aged <1 year in rural and urban counties, hypothesizing that infants living in rural counties experience significantly different hospital use compared with urban infants.

METHODS

Birth certificates for infants born in California hospitals between 1993 and 2005 and surviving to discharge were linked to hospital discharge records and death certificates during the first year of life, resulting in a study population of >6.4 million. Hospitalizations, cumulative LOS, readmission rates, and mortality were compared by using univariate and multivariable analysis for infants living in small rural, large rural, small urban, and large urban counties. Odds of hospitalization and cumulative LOS were also examined for common infant diagnoses.

RESULTS

Infants living in increasingly rural counties experienced decreasing rates of hospitalization and decreasing number of hospitalized days during the first year of life. Infants living in small rural counties experienced 370 hospital days per 1000 infants compared with 474 hospital days per 1000 infants living in large urban counties. In multivariable analysis, infants in large urban counties experienced increased odds of hospitalization (odds ratio: 1.20 [95% confidence interval: 1.06-1.36]) and increased hospitalized days (incidence risk ratio: 1.17 [95% confidence interval: 1.06-1.29]) compared with infants in small rural counties. For most common diagnoses, urban residence was associated with either increased odds of hospitalization or increased cumulative LOS.

CONCLUSIONS

Infants living in rural California counties experienced decreased hospital utilization, including decreased hospitalization and decreased LOS, compared with infants living in urban counties.

Premature infants born to adolescent mothers: health care utilization after initial discharge

OBJECTIVE

Premature infants have increased health care utilization after initial discharge compared with term infants. Young maternal age has been shown to impact health care utilization among term infants, but little is known about the impact of maternal age on health care utilization among premature infants. We compared health care utilization among premature infants of adolescent (aged < or = 19 years) and young adult (aged 20-29 years) mothers, hypothesizing that premature infants of adolescent mothers would have increased acute care utilization, while having decreased preventive care utilization.

METHODS

In this retrospective cohort study, we analyzed health care utilization of premature infants born to adolescent mothers (n = 76) compared with premature infants born to young adult mothers (n = 587) within a cohort of premature infants born between 1998 and 2001 in an integrated health care delivery system.

RESULTS

After controlling for illness severity, premature infants born to adolescent mothers had significantly increased odds of medical rehospitalizations (odds ratio 3.57, 95% confidence interval, 1.81-7.05) and emergency department visits (odds ratio 3.67, 95% confidence interval, 2.11-6.39) during the first year after initial discharge compared with premature infants born to young adult mothers. Differences in rehospitalization rates were significant within the first 3 months after discharge (P < .001). Frequency of preventive care visits was not significantly different between the two groups.

CONCLUSIONS

Despite similar severity of chronic illness and similar preventive care utilization, premature infants born to adolescent mothers had significantly increased rates of rehospitalizations and emergency department visits compared with premature infants born to young adult mothers.
