Mobile Health Apps, Family Caregivers, and Care Planning: Scoping Review.

BACKGROUND: People living with multiple chronic conditions (MCCs) face substantial challenges in planning and coordinating increasingly complex care. Family caregivers provide important assistance for people with MCCs but lack sufficient support. Caregiver apps have the potential to help by enhancing care coordination and planning among the health care team, including patients, caregivers, and clinicians. OBJECTIVE: We aim to conduct a scoping review to assess the evidence on the development and use of caregiver apps that support care planning and coordination, as well as to identify key factors (ie, needs, barriers, and facilitators) related to their use and desired caregiver app functionalities. METHODS: Papers intersecting 2 major domains, mobile health (mHealth) apps and caregivers, that were in English and published from 2015 to 2021 were included in the initial search from 6 databases and gray literature and ancestry searches. As per JBI (Joanna Briggs Institute) Scoping Review guidelines and PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews), 2 authors independently screened full texts with disagreements resolved by a third author. Working in pairs, the authors extracted data using a pilot-tested JBI extraction table and compared results for consensus. RESULTS: We identified 34 papers representing 25 individual studies, including 18 (53%) pilot and feasibility studies, 13 (38%) qualitative studies, and 2 experimental or quasi-experimental studies. None of the identified studies assessed an intervention of a caregiver app for care planning and coordination for people with MCCs. We identified important caregiver needs in terms of information, support, and care coordination related to both caregiving and self-care. We compiled desired functionalities and features enabling apps to meet the care planning and care coordination needs of caregivers, in particular, the integration of caregiver roles into the electronic health record. CONCLUSIONS: Caregiver needs identified through this study can inform developers and researchers in the design and implementation of mHealth apps that integrate with the electronic health record to link caregivers, patients, and clinicians to support coordinated care for people with MCCs. In addition, this study highlights the need for more rigorous research on the use of mHealth apps to support caregivers in care planning and coordination.

Age- and Race-Specific Changes in ESKD Incidence over Four Decades.

SIGNIFICANCE STATEMENT: ESKD incidence has changed substantially in the past four decades, but differences by age and race have been unexplored. Using data from the United States Renal Data System, we found that ESKD incidence rose for Black and White teenagers, adults, and older adults for two decades beginning in 1980. Growth in incidence slowed for most groups by 1993, and by 2006, the annual percent change (APC) in ESKD incidence had declined for all groups, except White adults, for whom rates continued to rise. By 2019, ESKD incidence among Black and White adolescents nearly returned to 1980 levels, but no other group achieved that degree of improvement. Nonetheless, the ESKD incidence rate among Black American patients exceeds that of White patients in every age group. Distinct patterns in ESKD incidence among patients of different age, sex, and racial groups are shown. These findings could reflect changes in dialysis acceptance rates, access to preventive health care, incidence of diabetes mellitus, implementation of evidence-based guidelines for treatment of CKD, or other unrecognized factors. There may be population-specific opportunities to change the growth of the US ESKD population and address current racial disparities. BACKGROUND: Substantial changes in ESKD incidence over four decades among Black and White Americans of different ages have been incompletely explored. METHODS: We analyzed United States Renal Data System data from 1980 to 2019 to determine ESKD incidence trends among Black and White adolescent (13-17 years), adult (18-64 years), and older adult (≥65) populations. We used the National Cancer Institute Joinpoint Regression Program to estimate annual percent change (APC) in ESKD incidence and to define points in time where a statistically significant change in APC slope occurred for each group. RESULTS: ESKD incidence rose after 1980 for all groups, although the trends differed ( P < 0.001). Growth in incidence slowed for most by 1993, and by 2006, the APC in ESKD incidence had declined for all groups, except White adults, for whom rates continued to rise ( P < 0.05). By 2019, ESKD incidence among Black and White adolescents nearly returned to 1980 levels, but no other group achieved that degree of improvement. Nonetheless, the ESKD incidence among Black American patients exceeds that of White patients in every age group. CONCLUSIONS: Distinct patterns in ESKD incidence among patients of different age, sex, and racial groups are shown. These findings could reflect changes in dialysis acceptance rates, access to preventive health care, incidence of diabetes mellitus, implementation of evidence-based guidelines for treatment of CKD, or other unrecognized factors.

Epidemiology of Infantile Ureteropelvic Junction Obstruction in the US.

OBJECTIVE: To describe sex- and diagnosis-specific comorbidities, outcomes, and secular trends associated with ureteropelvic junction obstruction (UPJO) in a large, real-world population diagnosed with hydronephrosis in infancy. MATERIALS AND METHODS: We identified all infants ≤1 year old with ≥1 claim in the Optum Clinformatics 2007-2020 nationwide population database and used univariable and multivariable Cox regression analyses to estimate associations of demographic and clinical characteristics of infants with a UPJO diagnosis with surgical status. RESULTS: Of 22,349 infants with hydronephrosis (1.1% of infants; males-1.4%, females-0.7%), 1722 (7.7%; 7.9%-males, 7.2%-females) had UPJO. Follow-up was ≥1 year in 1198 (70%) and ≥3 years in 555 (32%) cases, and UPJO repair was performed in 542 children (31.5%; 32.3%-males, 29.5%-females); 77.7% within 1 year and 97.3% within 3 years. UPJO repair was associated with prior urinary tract infection (UTI) (hazard ratio (HR) 1.41, 95% confidence interval (CI) 1.12-1.76) and South (HR 1.42, 95% CI 1.14-1.78) or Midwest (HR 1.60, 95% CI 1.26-2.04) geographic region but did not change over time. CONCLUSION: This population-based study provides a real-world view of postnatally diagnosed hydronephrosis, focusing on UPJO, for which 522 cases (∼1/3) had ≥3 years continuous coverage. UPJO-associated comorbidities were more common in females, and the frequencies of UPJO-associated surgery and comorbidities were higher than in other studies. Other than UTI, no other associated kidney or urinary tract diagnoses were associated with UPJO repair. We identified unique sex- and diagnosis-specific differences in associated comorbidities and interventions in children diagnosed with UPJO in the first year of life.

Assessing Progress Toward the Vision of a Comprehensive, Shared Electronic Care Plan: Scoping Review.

BACKGROUND: Care plans are central to effective care delivery for people with multiple chronic conditions. But existing care plans-which typically are difficult to share across care settings and care team members-poorly serve people with multiple chronic conditions, who often receive care from numerous clinicians in multiple care settings. Comprehensive, shared electronic care (e-care) plans are dynamic electronic tools that facilitate care coordination and address the totality of health and social needs across care contexts. They have emerged as a potential way to improve care for individuals with multiple chronic conditions. OBJECTIVE: To review the landscape of e-care plans and care plan-related initiatives that could allow the creation of a comprehensive, shared e-care plan and inform a joint initiative by the National Institutes of Health and the Agency for Healthcare Research and Quality to develop e-care planning tools for people with multiple chronic conditions. METHODS: We conducted a scoping review, searching literature from 2015 to June 2020 using Scopus, Clinical Key, and PubMed; we also searched the gray literature. To identify initiatives potentially missing from this search, we interviewed expert informants. Relevant data were then identified and extracted in a structured format for data synthesis and analysis using an expanded typology of care plans adapted to our study context. The extracted data included (1) the perspective of the initiatives; (2) their scope, (3) network, and (4) context; (5) their use of open syntax standards; and (6) their use of open semantic standards. RESULTS: We identified 7 projects for e-care plans and 3 projects for health care data standards. Each project provided critical infrastructure that could be leveraged to promote the vision of a comprehensive, shared e-care plan. All the e-care plan projects supported both broad goals and specific behaviors; 1 project supported a network of professionals across clinical, community, and home-based networks; 4 projects included social determinants of health. Most projects specified an open syntax standard, but only 3 specified open semantic standards. CONCLUSIONS: A comprehensive, shared, interoperable e-care plan has the potential to greatly improve the coordination of care for individuals with multiple chronic conditions across multiple care settings. The need for such a plan is heightened in the wake of the ongoing COVID-19 pandemic. While none of the existing care plan projects meet all the criteria for an optimal e-care plan, they all provide critical infrastructure that can be leveraged as we advance toward the vision of a comprehensive, shared e-care plan. However, critical gaps must be addressed in order to achieve this vision.

Racial and Socioeconomic Disparities in CKD in the Context of Universal Health Care Provided by the Military Health System.

RATIONALE & OBJECTIVE: Health-impeding social determinants of health-including reduced access to care-contribute to racial and socioeconomic disparities in chronic kidney disease (CKD). The Military Health System (MHS) provides an opportunity to assess a large, diverse population for CKD disparities in the context of universal health care. STUDY DESIGN: Cross-sectional study. SETTING & PARTICIPANTS: MHS beneficiaries aged 18 to 64 years receiving care between October 1, 2015, and September 30, 2018. PREDICTORS: Race, sponsor's rank (a proxy for socioeconomic status and social class), median household income by sponsor's zip code, and marital status. OUTCOME: CKD prevalence, defined by International Classification of Diseases, Tenth Revision codes and/or a validated, laboratory value-based electronic phenotype. ANALYTICAL APPROACH: Multivariable logistic regression compared CKD prevalence by predictors, controlling separately for confounders (age, sex, active-duty status, sponsor's service branch, and depression) and mediators (hypertension, diabetes, HIV, and body mass index). RESULTS: Of 3,330,893 beneficiaries, 105,504 (3.2%) had CKD. In confounder-adjusted models, the CKD prevalence was higher in Black versus White beneficiaries (OR, 1.67; 95% CI, 1.64-1.70), but lower in single versus married beneficiaries (OR, 0.77; 95% CI, 0.76-0.79). The prevalence of CKD was increased among those with a lower military rank and among those with a lower median household income in a nearly dose-response fashion (P < 0.0001). Associations were attenuated when further adjusting for suspected mediators. LIMITATIONS: The cross-sectional design prevents causal inferences. We may have underestimated the CKD prevalence, given a lack of data for laboratory tests conducted outside the MHS and the use of a specific CKD definition. The transient nature of the MHS population may limit the accuracy of zip code-level median household income data. CONCLUSIONS: Racial and socioeconomic CKD disparities exist in the MHS despite universal health care coverage. The existence of CKD disparities by rank and median household income suggests that social risks may contribute to both racial and socioeconomic disparities despite access to universal health care coverage.

A Scoping Review of the Economic Burden of Non-Cancerous Genitourinary Conditions.

OBJECTIVE: To provide a scoping review of the economic burden of non-cancerous genitourinary conditions (NCGUC). METHODS: A scoping review of the economic costs associated with NCGUC was conducted for literature published between 1990-2020. The articles were screened and relevant articles were selected for review. These articles were abstracted with information pertaining to the costs surrounding NCGUC. A descriptive analysis of the data was conducted. RESULTS: We found 3,298 articles in our scoping review. Of these, we found 39 relevant articles related to pelvic floor dysfunction and pelvic organ prolapse, interstitial cystitis, neurogenic bladder, nocturia, urinary tract infections, urolithiasis, urinary incontinence, benign prostatic hyperplasia, overactive bladder, and erectile dysfunction of which the data was reviewed. CONCLUSION: Although the data in estimating the economic burden is limited, existing evidence demonstrates a significant component of health care spending on NCGUC. Much of the spending is out-of-pocket and indirect costs that are difficult to measure which may increase the magnitude of the costs. There is a need for future research that takes a holistic look at the economic impact of NCGUC.

Noncancerous Genitourinary Conditions as a Public Health Priority: Conceptualizing the Hidden Burden.

OBJECTIVE: To provide a conceptual framework to guide investigations into burdens of noncancerous genitourinary conditions (NCGUCs), which are extensive and poorly understood. METHODS: The National Institute of Diabetes and Digestive and Kidney Diseases convened a workshop of diverse, interdisciplinary researchers and health professionals to identify known and hidden burdens of NCGUCs that must be measured to estimate the comprehensive burden. Following the meeting, a subgroup of attendees (authors of this article) continued to meet to conceptualize burden. RESULTS: The Hidden Burden of Noncancerous Genitourinary Conditions Framework includes impacts across multiple levels of well-being and social ecology, including individual (ie, biologic factors, lived experience, behaviors), interpersonal (eg, romantic partners, family members), organizational/institutional (eg, schools, workplaces), community (eg, public restroom infrastructure), societal (eg, health care and insurance systems, national workforce/economic output), and ecosystem (eg, landfill waste) effects. The framework acknowledges that NCGUCs can be a manifestation of underlying biological dysfunction, while also leading to biological impacts (generation and exacerbation of health conditions, treatment side effects). CONCLUSION: NCGUCs confer a large, poorly understood burden to individuals and society. An evidence-base to describe the comprehensive burden is needed. Measurement of NCGUC burdens should incorporate multiple levels of well-being and social ecology, a life course perspective, and potential interactions between NCGUCs and genetics, sex, race, and gender. This approach would elucidate accumulated impacts and potential health inequities in experienced burdens. Uncovering the hidden burden of NCGUCs may draw attention and resources (eg, new research and improved treatments) to this important domain of health.

The Inflection Point Model: A Model to Explore the Hidden Burdens of Non-Cancerous Genitourinary Conditions.

OBJECTIVE: To propose a conceptual model to identify points along the condition course where actions or inaction affect downstream burdens of non-cancerous genitourinary conditions (NCGUC). MATERIALS AND METHODS: The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) convened an interdisciplinary meeting to comprehensively consider the burdens of NCGUCs. Subsequently, the authors met monthly to conceptualize the model. RESULTS: Inflection points (IP) describe time points during a condition course that are sensitive to change. Our proposed Inflection Point Model (IPM) helps conceptualize burden/benefit trade-offs in any related decision and provides a platform to identify the downstream aggregate burden of a NCGUC across multiple socio-ecological levels at a single time point, which may be summed across the condition course to measure cumulative burden. Two personae demonstrate the utility of this model to better understand impacts of 2 common NCGUCs. CONCLUSION: The IPM may be applied in multiple contexts: narrowly to explore burden of a single NCGUC at a single IP; or more broadly, to address multiple conditions, multiple IPs, or multiple domains/levels of social ecology. Applying the IPM may entail combining population data describing prevalence of NCGUCs, associated behaviors, and resulting outcome patterns that can be combined with suitable mathematical models to quantify aggregate and cumulative burden. The IPM challenges stakeholders to expand from the individual to include broader levels of social ecology. Application of the IPM will undoubtedly identify data gaps and research needs that must be fulfilled to delineate and address the burden of NCGUCs.

CKD Prevalence in the Military Health System: Coded Versus Uncoded CKD.

RATIONALE & OBJECTIVE: Chronic kidney disease (CKD) is common but often goes unrecorded. STUDY DESIGN: Cross-sectional. SETTING & PARTICIPANTS: Military Health System (MHS) beneficiaries aged 18 to 64 years who received care during fiscal years 2016 to 2018. PREDICTORS: Age, sex, active duty status, race, diabetes, hypertension, and numbers of kidney test results. OUTCOMES: We defined CKD by International Classification of Diseases, Tenth Revision (ICD-10) code and/or a positive result on a validated electronic phenotype that uses estimated glomerular filtration rate and measures of proteinuria with evidence of chronicity. We defined coded CKD by the presence of an ICD-10 code. We defined uncoded CKD by a positive e-phenotype result without an ICD-10 code. ANALYTICAL APPROACH: We compared coded and uncoded populations using 2-tailed t tests (continuous variables) and Pearson χ2 test for independence (categorical variables). RESULTS: The MHS population included 3,330,893 beneficiaries. Prevalence of CKD was 3.2%, based on ICD code and/or positive e-phenotype result. Of those identified with CKD, 63% were uncoded. Compared with beneficiaries with coded CKD, those with uncoded CKD were younger (aged 45 ± 13 vs 52 ± 11 years), more often women (54.4% vs 37.6%) and active duty (20.2% vs 12.5%), and less often of Black race (18.5% vs 31.5%) or with diabetes (23.5% vs 43.5%) or hypertension (46.6% vs 77.1%; P < 0.001). Beneficiaries with coded (vs uncoded) CKD had greater numbers of kidney test results (P < 0.001). LIMITATIONS: Use of cross-sectional administrative data prevents inferences about causality. The CKD e-phenotype may fail to capture CKD in individuals without laboratory data and may underestimate CKD. CONCLUSIONS: The prevalence of CKD in the MHS is ~3.2%. Beneficiaries with well-known CKD risk factors, such as older age, male sex, Black race, diabetes, and hypertension, were more likely to be coded, suggesting that clinicians may be missing CKD in groups traditionally considered lower risk, potentially resulting in suboptimal care.

Disparities in Mental Health and Well-Being Among Black and Latinx Patients With Kidney Disease.

Black and Latinx individuals in the United States are afflicted disproportionately with kidney disease. Because of structural racism, social risk factors drive disparities in disease prevalence and result in worse outcomes among these patient groups. The impact of social and economic oppression is pervasive in physical and emotional aspects of health. In this review, we describe the history of race and ethnicity among black and Latinx individuals in the United States and discuss how these politicosocial constructs impact disparities in well-being and mental health. Lastly, we outline future research, clinical considerations, and policy considerations to eliminate racial and ethnic disparities in well-being among black and Latinx individuals with kidney disease.

Meeting report on the NIDDK/AUA Workshop on Congenital Anomalies of External Genitalia: challenges and opportunities for translational research.

Congenital anomalies of the external genitalia (CAEG) are a prevalent and serious public health concern with lifelong impacts on the urinary function, sexual health, fertility, tumor development, and psychosocial wellbeing of affected individuals. Complications of treatment are frequent, and data reflecting long-term outcomes in adulthood are limited. To identify a path forward to improve treatments and realize the possibility of preventing CAEG, the National Institute of Diabetes and Digestive and Kidney Diseases and the American Urological Association convened researchers from a range of disciplines to coordinate research efforts to fully understand the different etiologies of these common conditions, subsequent variation in clinical phenotypes, and best practices for long term surgical success. Meeting participants concluded that a central data hub for clinical evaluations, including collection of DNA samples from patients and their parents, and short interviews to determine familial penetrance (small pedigrees), would accelerate research in this field. Such a centralized datahub will advance efforts to develop detailed multi-dimensional phenotyping and will enable access to genome sequence analyses and associated metadata to define the genetic bases for these conditions. Inclusion of tissue samples and integration of clinical studies with basic research using human cells and animal models will advance efforts to identify the developmental mechanisms that are disrupted during development and will add cellular and molecular granularity to phenotyping CAEG. While the discussion focuses heavily on hypospadias, this can be seen as a potential template for other conditions in the realm of CAEG, including cryptorchidism or the exstrophy-epispadias complex. Taken together with long-term clinical follow-up, these data could inform surgical choices and improve likelihood for long-term success.

Racial/Ethnic Disparities in Atrial Fibrillation Treatment and Outcomes among Dialysis Patients in the United States.

BACKGROUND: Because stroke prevention is a major goal in the management of ESKD hemodialysis patients with atrial fibrillation, investigating racial/ethnic disparities in stroke among such patients is important to those who could benefit from strategies to maximize preventive measures. METHODS: We used the United States Renal Data System to identify ESKD patients who initiated hemodialysis from 2006 to 2013 and then identified those with a subsequent atrial fibrillation diagnosis and Medicare Part A/B/D. Patients were followed for 1 year for all-cause stroke, mortality, prescription medications, and cardiovascular disease procedures. The survival mediational g-formula quantified the percentage of excess strokes attributable to lower use of atrial fibrillation treatments by race/ethnicity. RESULTS: The study included 56,587 ESKD hemodialysis patients with atrial fibrillation. Black, white, Hispanic, and Asian patients accounted for 19%, 69%, 8%, and 3% of the population, respectively. Compared with white patients, black, Hispanic, or Asian patients were more likely to experience stroke (13%, 15%, and 16%, respectively) but less likely to fill a warfarin prescription (10%, 17%, and 28%, respectively). Warfarin prescription was associated with decreased stroke rates. Analyses suggested that equalizing the warfarin distribution to that in the white population would prevent 7%, 10%, and 12% of excess strokes among black, Hispanic, and Asian patients, respectively. We found no racial/ethnic disparities in all-cause mortality or use of cardiovascular disease procedures. CONCLUSIONS: Racial/ethnic disparities in all-cause stroke among hemodialysis patients with atrial fibrillation are partially mediated by lower use of anticoagulants among black, Hispanic, and Asian patients. The reasons for these disparities are unknown, but strategies to maximize stroke prevention in minority hemodialysis populations should be further investigated.

Development and Validation of a Pragmatic Electronic Phenotype for CKD.

BACKGROUND AND OBJECTIVES: Poor identification of individuals with CKD is a major barrier to research and appropriate clinical management of the disease. We aimed to develop and validate a pragmatic electronic (e-) phenotype to identify patients likely to have CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The e-phenotype was developed by an expert working group and implemented among adults receiving in- or outpatient care at five healthcare organizations. To determine urine albumin (UA) dipstick cutoffs for CKD to enable use in the e-phenotype when lacking urine albumin-to-creatinine ratio (UACR), we compared same day UACR and UA results at four sites. A sample of patients, spanning no CKD to ESKD, was randomly selected at four sites for validation via blinded chart review. RESULTS: The CKD e-phenotype was defined as most recent eGFR <60 ml/min per 1.73 m2 with at least one value <60 ml/min per 1.73 m2 >90 days prior and/or a UACR of ≥30 mg/g in the most recent test with at least one positive value >90 days prior. Dialysis and transplant were identified using diagnosis codes. In absence of UACR, a sensitive CKD definition would consider negative UA results as normal to mildly increased (KDIGO A1), trace to 1+ as moderately increased (KDIGO A2), and ≥2+ as severely increased (KDIGO A3). Sensitivity, specificity, and diagnostic accuracy of the CKD e-phenotype were 99%, 99%, and 98%, respectively. For dialysis sensitivity was 94% and specificity was 89%. For transplant, sensitivity was 97% and specificity was 91%. CONCLUSIONS: The CKD e-phenotype provides a pragmatic and accurate method for EHR-based identification of patients likely to have CKD.

Psychiatric Illness and Mortality in Hospitalized ESKD Dialysis Patients.

BACKGROUND AND OBJECTIVES: Limited existing data on psychiatric illness in ESKD patients suggest these diseases are common and burdensome, but under-recognized in clinical practice. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We examined hospitalizations with psychiatric diagnoses using inpatient claims from the first year of ESKD in adult and pediatric Medicare recipients who initiated treatment from 1996 to 2013. We assessed associations between hospitalizations with psychiatric diagnoses and all-cause death after discharge in adult dialysis patients using multivariable-adjusted Cox proportional hazards regression models. RESULTS: In the first ESKD year, 72% of elderly adults, 66% of adults and 64% of children had at least one hospitalization. Approximately 2% of adults and 1% of children were hospitalized with a primary psychiatric diagnosis. The most common primary psychiatric diagnoses were depression/affective disorder in adults and children, and organic disorders/dementias in elderly adults. Prevalence of hospitalizations with psychiatric diagnoses increased over time across groups, primarily from secondary diagnoses. 19% of elderly adults, 25% of adults and 15% of children were hospitalized with a secondary psychiatric diagnosis. Hazards ratios of all-cause death were higher in all dialysis adults hospitalized with either primary (1.29; 1.26 to 1.32) or secondary (1.11; 1.10 to 1.12) psychiatric diagnoses than in those hospitalized without psychiatric diagnoses. CONCLUSIONS: Hospitalizations with psychiatric diagnoses are common in pediatric and adult ESKD patients, and are associated with subsequent higher mortality, compared with hospitalizations without psychiatric diagnoses. The prevalence of hospitalizations with psychiatric diagnoses likely underestimates the burden of mental illness in the population.

Need for a Judicious Use of Nonsteroidal Anti-inflammatory Drugs to Avoid Community-Acquired Acute Kidney Injury.

Millions of Americans use over-the-counter analgesics on a daily basis, and nearly 100 million nonsteroidal anti-inflammatory drug (NSAID) prescriptions are filled per year. In high-risk patients, these medications can disrupt kidney hemodynamics and precipitate community-acquired acute kidney injury (CA-AKI). The risk of NSAID-associated CA-AKI increases 3- to 5-fold in patients taking renin-angiotensin system inhibitors and diuretics concurrently. CA-AKI increases the risk of developing chronic kidney disease (CKD) or accelerating progression of pre-existing CKD. Importantly, many cases of NSAID-induced CA-AKI may be avoided by identifying high-risk patients and providing patient and provider education on when to avoid these medications and minimize risk.

NIH research opportunities for the prevention and treatment for chronic conditions.

Chronic conditions constitute the leading cause of death and disability in the USA and constitute 86 per cent of the nation's annual healthcare expenses. Approximately half of all American adults have at least one chronic condition; 25 per cent of these Americans have two or more chronic conditions. The National Institutes of Health have funded many projects that explain epidemiology, risk factors, and prevention and treatment of chronic conditions, though research questions remain. This commentary discusses some past projects, current areas of interest, and funding opportunities from many NIH Institutes, Centers, and Offices.
