Cost of health care for paediatric patients with sickle cell disease: An analysis of resource use and costs in a European country.

BACKGROUND: While multiple studies have examined the cost of health care for one aspect of sickle cell disease care, few have focussed on the overall cost of comprehensive care for sickle cell disease. METHODS: We conducted a retrospective cohort study of children with sickle cell disease treated in a comprehensive care centre from 1 January 2015 to 31 December 2016. Health care utilisation of included patients was based upon data from two main sources. The clinical practice guideline was used to determine the expected resource use of routine comprehensive care (planned elective care), and the financial claims database was used to estimate real-world resource use associated with acute and inpatient care (additional care). RESULTS: A total of 125 children with sickle cell disease were analysed. Expenditures for these patients averaged €5049 [standard deviation (SD) €1634] per child per year. Total yearly costs per patient varied considerably, ranging from €669 to €84 010, and less than 15% of patients were responsible for 50% of the health care costs. The majority (37%) of costs was associated with inpatient hospital care, which increased by age group, 27% with diagnostics, 19% with treatment, 11% with outpatients' visits and 6% with emergency care. CONCLUSION: We have described real-world resource use and expenditures for children with sickle cell disease in a European comprehensive care centre. It seems that costs of a comprehensive approach with effective management in the outpatient setting is favourable when compared to episodic health care.

Impacto de un programa de optimización de uso de antimicrobianos en un hospital pediátrico de tercer nivel en Panamá / Impact of an antimicrobial stewardship program in a pediatric third level hospital in Panama

Resumen Introducción: Los programas de optimización de uso de antimicrobianos (PROA) se enfocan en el uso apropiado de antimicrobianos para ofrecer mejores resultados clínicos y menores riesgos de eventos adversos. Objetivos: Comparar consumo y costos de antimicrobianos antes y después de instauración de un programa de regulación de antimicrobianos y describir la proporción de resistencia de bacterias prioritarias. Métodos: Estudio cuasi-experimental, retrospectivo y prospectivo, descriptivo y analítico, que comparó el consumo y costo de antimicrobianos en un período pre- intervención (2007-2010) y un período post-intervención (2011-2017). Se realizó análisis descriptivo de resistencias bacterianas prioritarias. Resultados: El consumo de gentamicina, vancomicina, meropenem, cefotaxima, ceftazidima e imipenem disminuyó significativamente en el período post-intervención comparado con el período pre-intervención (p < 0,05), mientras que el consumo de amikacina, piperacilina/tazobactam, cefepime y levofloxacina en el período post-intervención mostró un aumento significativo. La reducción de costos no fue significativa para gentamicina, vancomicina, meropenem, cefotaxima, ceftazidima e imipenem. Para amikacina, cefepime, piperacilina/tazobactam y levofloxacina el aumento de costos no fue significativo. Los aislamientos de Acinetobacter baumannii, Klebsiella pneumoniae, Staphylococcus aureus y Enterococcus faecalis disminuyeron durante el período post-intervención. Conclusión: el PROA demostró disminución en consumo y costos de algunos antimicrobianos.

Abstract Background: Antimicrobial Stewardship Programs (ASP) focus in the appropriate use of antimicrobials to improve clinical results and minimize risk of adverse events. Aims: To compare consumption and costs of antimicrobials before and after the establishment of an antimicrobial stewardship program and to describe the resistance proportion of priority bacteria. Methods: Quasi-experimental, retrospective and prospective, descriptive and analytical study, to compare consumption and costs of antimicrobials in a pre- intervention period (2007-2010) and a post- intervention period (2011-2017). Additionally, a descriptive analysis of bacterial resistance from 2010 was performed. Results: Gentamicin, vancomycin, meropenem, cefotaxime, ceftazidime and imipenem consumption decreased significantly in the post-intervention period compared to the pre-intervention period (p < 0.05) while consumption of amikacin, piperacillin/tazobactam, cefepime and levofloxacin increased significantly in the post-intervention period. The reduction in costs was not significant for gentamicin, vancomycin, meropenem, cefotaxime, ceftazidime and imipenem, meanwhile, costs increased for amikacin, piperacillin/tazobactam, cefepime and levofloxacin, but this was not significant. The isolation of Acinetobacter baumannii, Klebsiella pneumoniae, Staphylococcus aureus and Enterococcus faecalis decreased during the post-intervention period. Conclusion: The ASP showed a decrease in consumption and costs of some antimicrobials.

The effects of integrating behavioral health into primary care for low-income children.

OBJECTIVE: To evaluate the impact of TEAM UP-an initiative that fully integrates behavioral health services into pediatric primary care in three Boston-area Community Health Centers (CHCs)-on health care utilization and costs. DATA SOURCES: 2014-2017 claims data on continuously enrolled children from a Massachusetts Medicaid managed care plan. STUDY DESIGN: We used a difference-in-difference approach with inverse probability of treatment weights to compare outcomes in children receiving primary care at TEAM UP CHCs versus comparison site CHCs, in the pre (2014-2016q2)- versus post (2016q3-2017)-intervention periods. Utilization outcomes included emergency department visits, inpatient admissions, primary care visits, and outpatient/professional visits (all cause and those with mental health (MH) diagnoses). Cost outcomes included total cost of care (inpatient, outpatient, professional, pharmacy). We further assessed differential effects by baseline MH diagnosis. PRINCIPAL FINDINGS: After 1.5 years, TEAM UP was associated with a relative increase in the rate of primary care visits (IRR = 1.15, 95% CI 1.04-1.27, or 115 additional visits/1000 patients/quarter), driven by children with a MH diagnosis at baseline. There was no significant change in avoidable health care utilization or cost. CONCLUSIONS: Expanding the TEAM UP behavioral health integration model to other sites has the potential to improve primary care engagement in low-income children with MH needs.

Pediatric Specialty Care Model for Management of Chronic Respiratory Failure: Cost and Savings Implications and Misalignment With Payment Models.

OBJECTIVE: To describe program design, costs, and savings implications of a critical care-based care coordination model for medically complex children with chronic respiratory failure. DESIGN: All program activities and resultant clinical outcomes were tracked over 4 years using an adapted version of the Care Coordination Measurement Tool. Patient characteristics, program activity, and acute care resource utilization were prospectively documented in the adapted version of the Care Coordination Measurement Tool and retrospectively cross-validated with hospital billing data. Impact on total costs of care was then estimated based on program outcomes and nationally representative administrative data. SETTING: Tertiary children's hospital. SUBJECTS: Critical Care, Anesthesia, Perioperative Extension and Home Ventilation Program enrollees. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The program provided care for 346 patients and families over the study period. Median age at enrollment was 6 years with more than half deriving secondary respiratory failure from a primary neuromuscular disease. There were 11,960 encounters over the study period, including 1,202 home visits, 673 clinic visits, and 4,970 telephone or telemedicine encounters. Half (n = 5,853) of all encounters involved a physician and 45% included at least one care coordination activity. Overall, we estimated that program interventions were responsible for averting 556 emergency department visits and 107 hospitalizations. Conservative monetization of these alone accounted for annual savings of $1.2-2 million or $407/pt/mo net of program costs. CONCLUSIONS: Innovative models, such as extension of critical care services, for high-risk, high-cost patients can result in immediate cost savings. Evaluation of financial implications of comprehensive care for high-risk patients is necessary to complement clinical and patient-centered outcomes for alternative care models. When year-to-year cost variability is high and cost persistence is low, these savings can be estimated from documentation within care coordination management tools. Means of financial sustainability, scalability, and equal access of such care models need to be established.

Neonatal Jaundice: Improved Quality and Cost Savings After Implementation of a Standard Pathway.

OBJECTIVES: Seattle Children's Hospital sought to optimize the value equation for neonatal jaundice patients by creating a standard care pathway. METHODS: An evidence-based pathway for management of neonatal jaundice was created. This included multidisciplinary team assembly, comprehensive literature review, creation of a treatment algorithm and computer order sets, formulation of goals and metrics, roll-out of an education program for end users, and ongoing pathway improvement. The pathway was implemented on May 31, 2012. Quality metrics before and after implementation were compared. External data were used to analyze cost impacts. RESULTS: Significant improvements were achieved across multiple quality dimensions. Time to recovery decreased: mean length of stay was 1.30 days for 117 prepathway patients compared with 0.87 days for 69 postpathway patients (P < .001). Efficiency was enhanced: mean time to phototherapy initiation was 101.26 minutes for 14 prepathway patients compared with 54.67 minutes for 67 postpathway patients (P = .03). Care was less invasive: intravenous fluid orders were reduced from 80% to 44% (P < .001). Inpatient use was reduced: 66% of prepathway patients were admitted from the emergency department to inpatient care, compared with 50% of postpathway patients (P = .01). There was no increase in the readmission rate. These achievements translated to statistically significant cost reductions in total charges, as well as in the following categories: intravenous fluids, laboratory, room cost, and emergency department charges. CONCLUSIONS: An evidence-based standard care pathway for neonatal jaundice can significantly improve multiple dimensions of value, including reductions in cost and length of stay.

A chief of service rotation as an alternative approach to pediatric otolaryngology inpatient care.

IMPORTANCE: Maintaining an outpatient practice and providing high-quality inpatient care pose significant challenges to the traditional call team approach. OBJECTIVE: To introduce a unique rotating hospitalist inpatient program and assess its clinical, educational, and financial impact. The chief of service (COS) program requires 1 attending physician to rotate weekly as chief of the inpatient service with no conflicting elective duties. DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective internal billing data review performed at a tertiary pediatric hospital. A total of 1241 patients were evaluated by the COS from October 2012 through October 2013. INTERVENTIONS: All patients were treated by the inpatient service under the supervision of the COS. MAIN OUTCOMES AND MEASURES: A retrospective analysis of patient encounters and procedures, including International Classification of Diseases, Ninth Revision (ICD-9) and Current Procedural Terminology (CPT) codes, locations of service, clinicians, service dates, and average weekly relative value units (RVUs). RESULTS: Over the study period, the COS was involved in the care of 1241 patients, generating 2786 billable patient encounters. The COS averaged 11.2 patient encounters per day. The most common reasons for consultation were respiratory distress, dysphagia, and stridor. Of patient encounters, 63.0% resulted in a procedure; 82.8% of those procedures were performed in the operating room with the most common being lower airway endoscopy (340 [19.4%]). The average weekly RVUs for the COS (232) were comparable with those of the average weekly outpatient clinic and procedural RVUs of the other otolaryngology faculty in the group (240). CONCLUSIONS AND RELEVANCE: The COS program was created to meet the clinical, educational, and organizational demands of a high-volume and high-acuity inpatient service. It is a financially sustainable model with unique advantages, particularly for the staff who maintain their outpatient practices without disruption and for the trainees who have the opportunity to work closely with the entire faculty. Patients are provided supervised evaluations and continuity of care. This rotating hospitalist program is a viable alternative to the full-time hospitalist staff model.

Variation in practice patterns and resource utilization surrounding management of intussusception at freestanding Children's Hospitals.

PURPOSE: To characterize variation in practice patterns and resource utilization associated with the management of intussusception at Children's Hospitals. METHODS: A retrospective cohort study (1/1/09-6/30/11) of 27 Children's Hospitals participating in the Pediatric Health Information System database was performed. Hospitals were compared with regard to their rates of operative management following attempted enema reduction, prophylactic antibiotic utilization, same-day discharge for those successfully managed non-operatively, 48-h readmission rates, and case-related cost and charges. RESULTS: 2544 patients were identified (median: 93 cases/center) with a median age of 17 months. The rate of operation following attempted enema reduction varied significantly across hospitals (overall rate: 21.1%: range: 11%-62.8%; p<0.0001). For patients managed non-operatively, significant variability was found for prophylactic antibiotic utilization (overall rate: 23.3%; range: 1.4%-93.2%; p<0.0001), same-day discharge (overall rate: 15.2%; range: 0%-83.8%; p<0.0001), readmission rates (overall rate: 17.5%; range: 5.3%-32.1%; p<0.0001), treatment-related costs (overall median: $2490; range: $829-$5905; p<0.0001), and charges (overall median: $6350; range: $2497-$10,306; p<0.0001). Variability in costs and charges was even greater when analyzing all patients (operative and non-operative) with intussusception (overall cost median: $2865; range: $1574-$6763; p<0.0001; overall charge median: $7110; range: $3544-$22,097; p<0.0001). CONCLUSION: Significant variation in practice patterns and resource utilization exists between Children's Hospitals in the management of intussusception. Prospective analysis of practice variation and appropriately risk-adjusted outcomes through a collaborative quality-improvement platform could accelerate the dissemination of best-practice guidelines for optimizing cost-effective care.

High resource hospitalizations among children with vaso-occlusive crises in sickle cell disease.

BACKGROUND: Vaso-occlusive crises (VOCs) contribute to frequent hospitalizations among children with sickle cell disease (SCD). The objective of this study was to identify factors associated with high resource utilization during hospitalizations for VOC. PROCEDURE: We analyzed pediatric discharges 0-18 years of age with a primary diagnosis of SCD with crisis from the 2006 Kids' Inpatient Database, a nationally representative sample of pediatric hospital discharges. High resource hospitalizations were defined as those in the highest decile for total charges. We conducted sample-weighted regression analyses to determine associations between independent variables (patient demographics, hospital characteristics, illness severity) and high resource use. RESULTS: There were 9,893 (0.371%) discharges for children with VOCs. Median total hospitalization charges were $10,691. In multivariate analysis, children 15-18 years of age (odds ratio [OR] 3.39, 95% confidence interval [CI] 2.54-4.53), 10-14 years of age (OR 2.72, 95% CI 2.07-3.59), and 5-9 years of age (OR 1.74, 95% CI 1.30-2.34) had higher odds of high resource hospitalizations compared to children 0-4 years of age. Care in a children's hospital had three times the odds of high resource use compared to care in a general hospital. Discharges with secondary diagnoses including pneumonia (OR 2.46, 95% CI 1.96-3.09) and constipation (OR 1.78, 95% CI 1.31-2.40) were also associated with high resource use. CONCLUSIONS: Older age and secondary diagnoses were associated with high resource use during VOC hospitalizations. These findings suggest the need to improve adherence to comprehensive care among older children to prevent VOCs and standardize protocols to manage VOC complications.

Pediatric hospitalist systems versus traditional models of care: effect on quality and cost outcomes.

BACKGROUND: Pediatric hospitalist systems are increasing in popularity, but data regarding the effects of hospitalist systems on the quality of care has been sparse, in part because rigorous metrics for analysis have not yet been established. We conducted a literature review of studies comparing the performance of pediatric hospitalists and traditional attendings. OBJECTIVE: To determine the effect of pediatric hospitalists on quality and outcome metrics such as length of stay, cost, patient satisfaction, mortality, readmission rates, and use of evidence-based medicine during care. RESULTS: A Medline literature search identified 11 studies that met criteria for inclusion. Five previously reviewed studies reported lengths of stay between 6% and 14% shorter for hospitalists. Five of the new studies evaluated lengths of stay, with 1 showing significantly lower length of stay and cost for a faculty model, 1 showing lower length of stay for hospitalists for all conditions, 1 for certain conditions only, and 2 showing no statistical difference. Six studies reported on readmission rate, with 4 showing no difference, 1 showing decreased readmissions for hospitalists, and 1 showing decreased readmissions for a traditional faculty service. Hospitalists self-report higher use of evidence-based guidelines. Few differences in patient satisfaction were reported. Mortality on the pediatrics wards is rare, and no studies were adequately powered to evaluate mortality rate. CONCLUSION: Hospitalists can improve the quality and efficiency of inpatient care in the pediatric population, but the effect is not universal, and mechanisms underlying demonstrated improvements are poorly understood. We propose 4 components to improve quality and value in hospital medicine systems: investment in comparative effectiveness research involving delivery system interventions, development and implementation of pediatric quality measures, better understanding of improvement mechanisms for hospital medicine systems, and increased focus on quality and value delivered by hospital medicine groups and individuals.

Pediatric short-bowel syndrome: the cost of comprehensive care.

BACKGROUND: Little information is available about the financial charges incurred by patients with short-bowel syndrome (SBS). This is particularly true for pediatric SBS patients who receive some of the most complex medical care. OBJECTIVES: The aims of this study were to determine the total cost of care for these patients and to analyze their utilization of home and hospital-based health care services. DESIGN: This was a retrospective review of the total charges incurred by 41 children with SBS over the past decade, encompassing both inpatient and home-care charges. RESULTS: The mean (+/- SD) total cost of care for pediatric SBS was US$505 250 +/- US$248 398 (corrected for inflation to the year 2005) for the first year of care alone. Inpatient hospitalization accounted for most of these expenses (US$416 818 +/- US$242 689, or 82% of the total), and this was attributable to prolonged requirements for intensive care resources, numerous surgical procedures, and multiple readmissions during the first year of diagnosis. Hospital-based costs steadily declined in subsequent years, but home-care services, in stark contrast, unexpectedly increased every year for the first 5 y of diagnosis-a trend that was highly significant (P < 0.005), reaching US$184 520 +/- US$111 075 for the fifth year of home care. This increasing cost was attributable to increasing complications of parenteral nutrition, especially infectious complications. Although per-patient charges varied widely, the mean total cost of care per child over a 5-y period was US$1 619 851 +/- US$1 028 985. A strong correlation was found between higher charges and infants with <10% of predicted small-bowel length. CONCLUSIONS: This study was the first to calculate the total costs for pediatric SBS patients and to provide an in-depth analysis of these patients' actual utilization of health care services. This information may help guide health care providers and families who have children with SBS. The comprehensive care of pediatric SBS patients costs significantly more than has previously been estimated. Contrary to previous views, home care significantly increases each year after diagnosis.

Modelling the resource implications and budget impact of new reimbursement guidelines for the management of cow milk allergy in Finland.

OBJECTIVE: To assess the impact of the decision by Kela (The Social Insurance Institution) to adopt guidelines for the management of food allergies in children, developed by the Finnish Medical Society Duodecim, as the basis for reimbursing clinical nutrition preparations for the treatment of cow milk allergy (CMA) in Finland. METHODS: A decision model was constructed using published clinical outcomes and clinician-derived resource utilisation estimates. The model was used to estimate the net resource implications and associated costs of Kela's new policy for the annual cohort of 1443 new CMA sufferers over the first 6 months following referral to a specialist. The analysis was conducted from the perspective of Kela, patients and Finnish society. RESULTS: Kela's new policy for reimbursing clinical nutrition preparations for the treatment of CMA is expected to increase healthcare resource use, including a 10% increase in the number of specialist visits over the first 6 months following referral. Consequently, Kela's 6-monthly expenditure on 1443 new CMA sufferers following referral is expected to increase by 12% from 889,389 euros to 992,761 euros. Additionally, parents' costs are expected to increase by 10% and fathers' absenteeism from work to increase by 11% within the first 6 months following referral. CONCLUSION: It is important to validate guidelines in clinical practice before their implementation. Within the limitations of our model, Kela's new criteria for reimbursing clinical nutrition preparations for the treatment of CMA is expected to increase healthcare resource use in paediatric departments in public hospitals in Finland and increase costs to Kela, patients and Finnish society.

Costs of meals and parking for parents of hospitalised children in Australia.

BACKGROUND: The aim of this investigation was to examine the cost of parents' food and parking during a child's admission to two paediatric health facilities in a capital city in Australia and to make recommendations to alleviate the cost of admission. METHODS: A survey was undertaken of hospital facilities and food outlets, recording the type and cost of food available, opening times of the facilities and parking costs. RESULTS: Costs for food and parking for one accompanying parent can exceed A$200 per week. At one hospital no full meals were available. For parents of children admitted for long periods or those on low incomes and/or social security benefits, this would be a large proportion of their weekly income. RECOMMENDATIONS: Funding to paediatric hospitals should include meals for parents, especially breastfeeding mothers. Access to staff canteens would afford parents the opportunity to eat proper meals. Parking for parents should be free.

Children in need of Pharmacare: medication funding requests at the Toronto Hospital for Sick Children.

OBJECTIVES: Although a national Pharmacare program ensuring access to and affordability of needed medications has repeatedly been cited as a priority to policymakers, 20% of families remain either uninsured or under-insured. The Hospital for Sick Children's Patient Amenities Fund (PAF) covers out-of-pocket medication expenses for inpatient and outpatient children. The research objectives were to 1) examine family demographics and socio-economic status (SES), the types of medications requested and government program process issues of PAF applicants in 1998 and 1999, and 2) describe trends in PAF requests from 1998 to 2000. METHODS: Data were extracted retrospectively from fund requests, charts and social work and discharge planning reports. Descriptive statistics were used to summarize the data and to examine time trends. RESULTS: Eighty-six applicants submitted 112 requests from 1998-1999. Most were for children with cancer, neurological disorders and transplant patients. Medication expenditures were 22,408 dollars in 1999, a 39% increase over 1998. Most requests came from two-parent nuclear families where one or both parents were employed. High deductibles, waiting time, application form complexity and request denials were cited as problems encountered with government drug plans. DISCUSSION: The findings suggest that for provinces that do not provide universal drug insurance programs, relying on a patchwork of government plans and community agencies may not be effective in ensuring easy and timely access to necessary medications for children.

Cost-utility analysis of patient care in children with meningeal signs.

OBJECTIVES: We designed a model of diagnostic and therapeutic interventions applied in children with meningeal signs. Using this model, we determined in a cost-utility analysis the consequences for society of different diagnostic strategies in terms of quality-adjusted life-years (QALYs) and costs. METHODS: Data were used from 360 children (0.1-15 years) visiting the pediatric emergency department of the Sophia Children's Hospital Rotterdam, The Netherlands (1988-98) with meningeal signs. Model inputs included probabilities of meningitis and adverse outcome, QALYs for years lived with long-term sequelae, and costs of tests and treatments. Mean outcome measures were costs and effects of diagnostic and therapeutic interventions in children suspected of bacterial meningitis, key determinants of the model outcomes, and evaluation of alternative diagnostic strategies and two vaccination programs in an analysis. RESULTS: The population comprised 99 children with bacterial meningitis (adverse outcome in 10), 36 with serious other bacterial infections, and 225 with self-limiting diseases. Key determinants were the risk of bacterial meningitis or sequelae, costs of treatment, and long-term morbidity. Minimizing lumbar punctures and empirical treatments using a diagnostic decision rule, without missing a single case of meningitis, was a dominant strategy to actual practice. Vaccination strategies of Streptococcus pneumoniae and Neisseria meningitidis resulted in our model in incremental cost-utility ratios of 401,965 Euro dollar ([symbol: see text])/QALY and [symbol: see text]22,635/QALY, respectively. CONCLUSIONS: Costs of long-term morbidity of bacterial meningitis largely outweigh diagnostic and treatment costs. Modeling interventions in children at risk of bacterial meningitis should include long-term consequences in terms of costs and QALYs.

A new economic benchmark for surgical treatment of appendicitis.

Cost reduction in the management of common surgical diseases such as appendicitis has become paramount for the survival of children's hospitals. We designed a clinical pathway to treat appendicitis with the goal of reducing cost and hospital length of stay (LOS) while maintaining quality of care. From September 1995 through December 1996, patients with nonperforated appendicitis (NPApp) and perforated appendicitis with peritonitis (PApp) were enrolled into a clinical pathway. NPApp patients were discharged when tolerating a regular diet. PApp patients were discharged if the following criteria were met: temperature < 38.5 degrees C for 24 hours, WBC < 14,000 on postoperative day 3, tolerating diet, and transition to oral analgesics accomplished. Hospital LOS and actual hospital costs in pathway patients were compared with those of historic controls. Patients with appendicitis from the Pediatric Health Information Systems (PHIS) database, a consortium of 20 children's hospitals in the United States, served as concurrent controls. Hospital LOS and hospital charges in PHIS NPApp and PApp patients from our institution were compared with national PHIS database patients. Mean LOS and hospital costs for both NPApp and PApp pathway patients were significantly decreased compared with historic controls (P < 0.05). Mean LOS and hospital charges in our institution's PHIS NPApp and PApp patients were also significantly decreased compared with the national PHIS database (P < 0.05). Innovative approaches such as these are necessary for the survival of children's hospitals in an increasingly cost competitive healthcare market.

Physician outcome measurement: review and proposed model.

As health care moves from a free-for-service environment to a capitated arena, outcome measurements must change. ABC Children's Medical Center is challenged with developing comprehensive outcome measures for an employed physician group. An extensive literature review validates that physician outcomes must move beyond revenue production and measure all aspects of care delivery. The proposed measurement model for this physician group is a trilogy model. It includes measures of cost, quality, and service. While these measures can be examined separately, it is imperative to understand their integration in determining an organization's competitive advantage. The recommended measurements for the physician group must be consistent with the overall organizational goals. The long-term impact will be better utilization of resources. This will result in the most cost effective, quality care for the health care consumer.
