Adherence to adhesive patch electrocardiographic monitoring among adults with disabilities.

BACKGROUND: Individuals with developmental and/or intellectual disabilities (I/DD) are at a greater risk for atrial fibrillation (AF), the most common type of cardiac arrhythmia. AF is associated with heart failure, stroke, poor mental health, and reduced quality of life. Management and treatment decisions are based on the ability to detect AF; however, noninvasive, remote cardiac monitoring may not be tolerated by individuals with I/DD. OBJECTIVE: To examine adherence to the placement of an ambulatory cardiac rhythm monitoring patch device by adult patients with I/DD. METHODS: Investigators extracted chart data from a consecutive series of adult patients (18 years+) who received the patch device as part of standard treatment at an adult health center between November 1, 2015 and October 31, 2019. RESULTS: A total of 95 patients were included in data analysis. Average age of subjects was 53.8 ± 13.9 years (range: 20.2-88.5); 66.7% were male. All subjects had intellectual disabilities as follows: mild, 37.9%; moderate, 29.5%; severe, 21.0%; and, profound, 11.6%. With a prescribed duration of 14 days, subjects wore the device a median (interquartile range [IQR]) of 12.2 days (4.1-14.0); total analysis time was a median of 9.5 days (3.4-13.5). A total of 29 subjects (30.5%) received cardiac diagnoses not previously identified (median = 1 new diagnosis; range: 1-5). CONCLUSIONS: This pilot study suggests the possible utility of an ambulatory monitoring patch device in an adult population with I/DD. Investigators recommend larger studies to confirm such preliminary findings to ultimately improve clinical management and patient quality of life.

Challenges to Professional Success for Women Plastic Surgeons: An International Survey.

BACKGROUND: Female plastic surgeons face specific challenges in their careers that impact lifestyle and professional choices. OBJECTIVE: The authors sought to delineate these specific issues further through means of an anonymous survey and to suggest areas for improvement. METHODS: In August 2017, a link to an online email questionnaire via SurveyMonkey.com was sent to 398 women members of the International Society of Aesthetic Plastic Surgery, which included questions on demographics, surgical training, practice characteristics and preferences, leadership and professional activities, marriage and childcare, financial status, workplace sexism and sexual harassment and surgeon attitudes. RESULTS: A total of 138 female plastic surgeons responded to the survey for a response rate of 34.7%. Critical issues most cited by respondents included work-life balance and childcare responsibilities, sexual harassment and the lack of gender parity at meetings. CONCLUSIONS: Plastic surgery training programs, institutions and societies should acknowledge the additional challenges that female surgeons face. The greatest areas for improvement include the balance of work and family responsibilities, addressing the prevalence of sexual harassment and improved representation at scientific meetings.

Implementing a Hospital-Based Safe Sleep Program for Newborns and Infants.

BACKGROUND: An unsafe sleep environment remains the leading contributor to unexpected infant death. PURPOSE: To determine the effectiveness of a quality improvement initiative developed to create a hospital-based safe sleep environment for all newborns and infants. METHODS: A multidisciplinary team from the well-baby nursery (WBN) and neonatal intensive care unit (NICU) of a 149-bed academic, quaternary care, regional referral center developed and implemented safe sleep environments within the hospital for all prior to discharge. To monitor compliance, the following were tracked monthly: documentation of parent education, caregiver surveys, and hospital crib check audits. On the inpatient general pediatric units, only hospital crib check audits were tracked. Investigators used Plan-Do-Study-Act (PDSA) cycles to evaluate the impact of the initiative from October 2015 through February 2018. RESULTS: Safe sleep education was documented for all randomly checked records (n = 440). A survey (n = 348) revealed that almost all caregivers (95.4%) reported receiving information on safe infant sleep. Initial compliance with all criteria in WBN (n = 281), NICU (n = 285), and general pediatric inpatient units (n = 121) was 0%, 0%, and 8.3%, respectively. At 29 months, WBN and NICU compliance with all criteria was 90% and 100%, respectively. At 7 months, general pediatric inpatient units' compliance with all criteria was 20%. IMPLICATIONS FOR PRACTICE: WBN, NICU and general pediatric inpatient unit collaboration with content experts led to unit-specific strategies that improved safe sleep practices. IMPLICATIONS FOR RESEARCH: Future studies on the impact of such an initiative at other hospitals are needed.

Is Earlier Better? The Relationship between Age When Starting Early Intervention and Outcomes for Children with Autism Spectrum Disorder: A Selective Review.

Although the conventional wisdom is that "earlier is better" when it comes to intervention for children with ASD, it is not clear what evidence exists to support this notion. This review examined a group of studies that addressed outcomes for young children with ASD who started early intervention at a range of ages. The review was selective by including only papers that examined the age of initiation of treatment as well as baseline cognitive, language, or adaptive level and, in addition, employed a method to control for the covariance between early ability level and age of beginning intervention. Fourteen studies were identified and then compared on methods and outcomes. The support for "earlier is better" was mixed, but it was clear that complex relationships among predictor variables need to be explored in order to understand the role of age of starting early intervention for later outcomes.

Technology and social media use by adult patients with intellectual and/or developmental disabilities.

BACKGROUND: Technology and social media offer individuals with intellectual and/or developmental disabilities (I/DD) unique and innovative ways to facilitate active participation in their own healthcare process. What remains unclear is the extent to which devices are currently used by this growing patient population. OBJECTIVE: To explore the prevalence of technology and social media use, as well as the possible barriers, among adult patients with I/DD. METHODS: A cross-sectional study utilizing an anonymous, accessible survey was used to obtain data from all adult patients (18 + years of age) with I/DD presenting for primary care services at a healthcare facility in New York between September and December of 2016. RESULTS: A total of 370 individuals completed the survey (529 approached, 69.9% response rate). Less than half (44.6%) of respondents used devices such as a tablet, smartphone or desktop; most (86.8%) did not use social media. Only 21.6% of respondents indicated that they use some type of assistive technology. While some respondents (46.0%) were identified by their caregivers as having a disability that would prevent them from learning/using technology, other respondents reported having no challenges (18.0%), needing training and/or ongoing support (7.4%), or being uncertain as to whether they would experience any challenges (15.5%). CONCLUSIONS: Many adult patients with I/DD do not use technology and social media that could promote self-determination and participation in their healthcare. Continued efforts must be made to promote technology use among adults with I/DD and to ensure that appropriate training is available for both the individual and his/her caregivers to achieve adoption and utilization.

Intensity of Vasopressor Therapy for Septic Shock and the Risk of In-Hospital Death.

CONTEXT: Given the high mortality of 30%-60% associated with septic shock, distinguishing which patients do or do not have a reasonable chance of surviving with aggressive treatment could help clinicians and families make informed decisions. OBJECTIVES: To determine if intensity of vasopressor therapy accurately predicts in-hospital death. METHODS: This observational cohort study analyzed in-hospital mortality as a function of intensity of vasopressor therapy in a consecutive series of adults with septic shock treated over a four-year period. Receiver operating characteristic curve analysis assessed the overall strength of the intensity-mortality relationship. RESULTS: A total of 808 patients with septic shock experienced an in-hospital death rate of 41.0% (331/808; 95% CI, 38.5%-44.5%). The greater the peak number of vasopressors required, the higher the death rate, which reached 92.3% (12/13; 95% CI, 79.4%-100.0%) when three different pressors were being infused at full dose. The receiver operating characteristic curve analysis revealed that number of simultaneous vasopressors and vasopressor dose load performed equally well in predicting death or survival. CONCLUSION: When a standard full dose of a vasopressor fails to normalize blood pressure in a patient with septic shock, escalation begins to yield diminishing returns as the dose and multiplicity of agents approach practical upper limits. Although it is not possible to specify a precise cutoff for limiting vs. intensifying therapy, a mortality of 80% or higher-characterized by two or more concurrent vasopressors at full dose-should prompt shared decision making with the patient's family.

Organ Distribution of 13N Following Intravenous Injection of [13N]Ammonia into Portacaval-Shunted Rats.

Ammonia is neurotoxic, and chronic hyperammonemia is thought to be a major contributing factor to hepatic encephalopathy in patients with liver disease. Portacaval shunting of rats is used as an animal model to study the detrimental metabolic effects of elevated ammonia levels on body tissues, particularly brain and testes that are deleteriously targeted by high blood ammonia. In normal adult rats, the initial uptake of label (expressed as relative concentration) in these organs was relatively low following a bolus intravenous injection of [13N]ammonia compared with lungs, kidneys, liver, and some other organs. The objective of the present study was to determine the distribution of label following intravenous administration of [13N]ammonia among 14 organs in portacaval-shunted rats at 12 weeks after shunt construction. At an early time point (12 s) following administration of [13N]ammonia the relative concentration of label was highest in lung with lower, but still appreciable relative concentrations in kidney and heart. Clearance of 13N from blood and kidney tended to be slower in portacaval-shunted rats versus normal rats during the 2-10 min interval after the injection. At later times post injection, brain and testes tended to have higher-than-normal 13N levels, whereas many other tissues had similar levels in both groups. Thus, reduced removal of ammonia from circulating blood by the liver diverts more ammonia to extrahepatic tissues, including brain and testes, and alters the nitrogen homeostasis in these tissues. These results emphasize the importance of treatment paradigms designed to reduce blood ammonia levels in patients with liver disease.

Autism Spectrum Disorder Screening Instruments for Very Young Children: A Systematic Review.

Research on ASD in infancy has provided a rationale for developing screening instruments for children from the first year of life to age of 18 months. A comprehensive literature search identified candidate screening tools. Using methodological probe questions adapted from the Quality Assessment of Diagnostic Accuracy Studies (QUADAS), two Level 1 and three Level 2 screening instruments were reviewed in detail. Research evidence conclusions were that instrument development was in beginning phases, is not yet strong, and requires further development. Clinical recommendations were to continue vigilant developmental and autism surveillance from the first year on but to use the screening instruments per se only for high-risk children rather than for population screening, with considerations regarding feasibility for individual settings, informing caregivers about strengths and weaknesses of the tool, and monitoring new research.

The impact of a hospital-based educational video on maternal perceptions and planned practices of infant safe sleep.

PURPOSE: To evaluate whether an educational video would impact infant sleep practices among new mothers. DESIGN AND METHODS: Survey responses of new mothers who did (n = 43) versus did not (n = 49) watch the educational video were compared to identify differences in observed and planned infant sleep practices. RESULTS: Mothers who watched the video were more likely to observe safe sleep practices while in the hospital (67.4% vs. 46.9%, p < .05). They were also less likely to plan for (unsafe) side positioning (23.9% vs. 7.1%, p < .05). PRACTICE IMPLICATIONS: Given the potentially fatal consequence of unsafe sleep, a brief video provided by nursing staff can be a prudent component of new parent education.

Is fluorescence under an alternate light source sufficient to accurately diagnose subclinical bruising?

This single-blinded, randomized validation study was conducted to evaluate whether fluorescence under alternate light sources (ALS) is sufficient to diagnose subclinical bruising (bruising not visible under white light). Standardized trauma was induced on randomly selected ventral forearms. On days 1, 7, and 14 investigators independently examined case forearms under white light for perceived bruising and under ALS for fluorescence and compared body maps. 56 case and 62 control forearms (n = 118) were examined. Sensitivity of ALS on days 1, 7, and 14 was 76.8%, 69.6%, and 60.7%, respectively, compared to 69.6%, 60.0%, and 32.1% for white light. The specificity of ALS on days 1, 7, and 14 was 51.6%, 59.7%, and 53.2%, respectively, compared to 71.0%, 81.4%, and 86.9% for white light. ALS has increased sensitivity yet low specificity compared to white light in accurately detecting bruises. Fluorescence under ALS is not sufficient to accurately or responsibly diagnose subclinical bruising.

Timely pain management in the emergency department.

BACKGROUND: Delivering timely pain relief remains a challenge for most emergency departments. OBJECTIVE: To evaluate the effectiveness of a policy aimed at delivering analgesics within 30 min to patients presenting to an emergency department with severe pain. METHODS: Subjects were aged ≥19 years, had a principal diagnosis of renal colic, hip fracture, or sickle cell disease, reported a pain score ≥8 on a scale of 0 to 10 at triage, and continued to report a score in this range until receiving analgesia. The study compared proportions of patients receiving analgesics within the 30-min target, median time to analgesic administration, and median time to relief of severe pain (decline in pain level to score <8) during 6 months before vs. 6 months after implementation of the new pain management policy. RESULTS: Paradoxically, the median total waiting time to analgesic administration increased from 64 min (n = 75) to 80 min (n = 70) after policy implementation (p = 0.01), and the proportion of patients receiving analgesics within 30 min declined from 17% (13/75) to 7% (5/70) (p = 0.08). Median time to relief of severe pain did not differ significantly between periods (130.5 vs. 153 min; p = 0.31). CONCLUSIONS: After implementation of the new pain management policy, the proportion of patients with severe pain receiving analgesics within 30 min actually declined. Although a 30-min target may be unrealistic, it seems reasonable to conclude that something is wrong when patients with notoriously painful conditions must typically wait 1-2 h to obtain relief. Given the millions of individuals who receive care in emergency departments nationwide each year, the suffering caused by delays occurs on a large scale, so creative approaches are clearly needed to overcome the obstacles.

Vitamin D and retinopathy in adults with diabetes mellitus.

OBJECTIVE To explore a hypothesized association between vitamin D inadequacy and diabetic retinopathy. METHODS This cross-sectional study analyzed data from individuals aged 40 years and older with diabetes mellitus who participated in the interview and medical examination components of the Third National Health and Nutrition Examination Survey conducted from October 1, 1988, through September 30, 1994. The relationship between diabetic retinopathy and serum 25-hydroxyvitamin D concentration was evaluated using regression analysis in the presence of demographic and clinical covariates, such as age, race, obesity, and persistent hyperglycemia. RESULTS On the basis of the 1790 adults with diabetes who met the study's inclusion criteria, the percentage of individuals with vitamin D deficiency increased with severity of retinopathy: no retinopathy, 27.9%; mild, 28.2%; moderate to severe, 43.2%; and proliferative, 64.6% (P = .01). Regression analysis of retinopathy severity vs serum 25-hydroxyvitamin D concentration did not demonstrate a statistically significant relationship between the two variables (P = .07). CONCLUSIONS This study found an association between severity of diabetic retinopathy and prevalence of vitamin D deficiency, but the findings were inconclusive about the existence of a relationship between retinopathy severity and serum 25-hydroxyvitamin D concentration. Given previous research indicating possible anti-inflammatory and antiangiogenic properties of vitamin D, the connection between vitamin D and diabetic retinopathy warrants further study.

The influence of career stage, practice type and location, and physician's sex on surgical practices among board-certified plastic surgeons performing breast augmentation.

BACKGROUND: Breast augmentation is the most commonly performed cosmetic surgical procedure in the United States, but surgeon preferences in terms of technique and postoperative care regimen vary widely. OBJECTIVES: The authors investigated the influence of career stage, practice type and location, and physician's sex on surgical technique preferences among board-certified plastic surgeons performing breast augmentation. METHODS: In October 2009, an online survey was e-mailed to all active members of the American Society of Plastic Surgeons practicing within the United States. Response frequencies were calculated and correlated with surgeon demographics. RESULTS: From the pool of 4737 respondents, 898 responses were received (18.9%). Surgeons performing breast augmentation were more frequently male, between 46 and 65 years old, and had practiced for at least 20 years in solo private practice in a suburban setting. Surgical volume most frequently consisted of 10% to 25% cosmetic surgery, with 10 to 50 breast augmentations performed per year. Surgeons in practice for five years or less were more likely to use smooth, round silicone gel-filled implants, to select implants smaller than 300 cc, to use the dual-plane pocket, and to recommend yearly follow-up. Surgeons in practice for more than 20 years were more likely to select saline implants, utilize the subglandular plane, perform closed capsulotomy, and place drains. Surgeons at academic centers performed fewer breast augmentation surgeries and placed smaller implants than those in private practice, while surgeons in suburban locations performed more breast augmentations than those in urban or rural locations. Surgeons in the West performed the greatest number of augmentations, although the largest-sized implants were placed in the Southwest. Compared with men, women surgeons appeared significantly less likely to use saline implants, were less likely to perform more than 100 breast augmentations per year, and were significantly more likely to place implants less than 300 cc. CONCLUSIONS: Surgical preferences were associated with years in practice and included differences in technique and postoperative care. Practice location was associated with differences in procedural volume, implant size, incision location, and recommended follow-up time, while practice type was related to surgical volume, implant size, implant location, and percentage of cosmetic surgery performed.

Parent education by maternity nurses and prevention of abusive head trauma.

OBJECTIVE: A consortium of the 19 community hospitals and 1 tertiary care children's hospital that provide maternity care in the New York State Hudson Valley region implemented a program to teach parents about the dangers of shaking infants and how to cope safely with an infant's crying. This study evaluated the effectiveness of the program in reducing the frequency of shaking injuries. METHODS: The educational program, which was delivered by maternity nurses, included a leaflet explaining abusive head trauma ("shaken baby syndrome") and how to prevent it, an 8-minute video on the subject, and a statement signed by parents acknowledging receipt of the information and agreeing to share it with others who will care for the infant. Poisson regression analysis was used to compare the frequency of shaking injuries during the 3 years after program implementation with the frequency during a 5-year historical control period. RESULTS: Sixteen infants who were born in the region during the 8-year study period were treated at the children's hospital for shaking injuries sustained during their first year of life. Of those infants, 14 were born during the 5-year control period and 2 during the 3-year postimplementation period. The decrease from 2.8 injuries per year (14 cases in 5 years) to 0.7 injuries per year (2 cases in 3 years) represents a 75.0% reduction (P = .03). CONCLUSIONS: Parent education delivered in the hospital by maternity nurses reduces newborns' risks of sustaining an abusive head injury resulting from shaking during the first year of life.

Impact of AOA status and perceived lifestyle on career choices of medical school graduates.

BACKGROUND: Based upon student ratings of such factors as predictable work hours and personal time, medical specialties have been identified as lifestyle friendly, intermediate, or unfriendly. Lifestyle friendly programs may be more desirable, more competitive, and for students elected to the Alpha Omega Alpha (AOA) Honor Medical Society, more attainable. OBJECTIVE: The objective of this study was to evaluate whether AOA students increasingly entered lifestyle friendly residency programs and whether trends in program selection differed between AOA and non-AOA graduates. DESIGN: This retrospective cohort study examined PGY-2 data from the Association of American Medical Colleges and the 12 allopathic schools in the Associated Medical Schools of New York. PARTICIPANTS: Data on 1987-2006 graduates from participating schools were evaluated. MAIN MEASURES: Residency program selection over the 20-year period served as the main outcome measure. KEY RESULTS: AOA graduates increasingly entered lifestyle-friendly residencies--from 12.9% in 1987 to 32.6% in 2006 (p < 0.01). There was also a significant decrease in AOA graduates entering lifestyle unfriendly residencies, from 31.6% in 1987 to 12.6% in 2006 (p < 0.01). Selection of lifestyle intermediate residencies among AOA graduates remained fairly stable at an average of 53%. Similar trends were found among non-AOA students. However, within these categories, AOA graduates increasingly selected radiology, dermatology, plastic surgery and orthopedics while non-AOA graduates increasingly selected anesthesiology and neurology. CONCLUSIONS: While lifestyle factors appear to influence residency program selection, AOA graduates differentially were more likely to either choose or attain certain competitive, lifestyle-friendly specialties. Health care reform should be targeted to improve lifestyle and decrease income disparities for specialties needed to meet health manpower needs.

Breastfeeding education and support services offered to pediatric residents in the US.

OBJECTIVE: The American Academy of Pediatrics (AAP) encourages pediatricians to support the practice of breastfeeding and residency educators to develop formal curricula in breastfeeding education. Few studies, however, describe breastfeeding education or support services currently provided to pediatric residents in the United States. The goals of this study were to investigate breastfeeding training offered during 3-year pediatric residency programs and to describe residency programs' policies and services for residents who breastfeed. METHODS: We conducted a cross-sectional study using a Web-based survey of pediatric program directors regarding breastfeeding education and support services for residents. RESULTS: Seventy percent of program directors (132 of 189) completed the survey, with 77.3% of respondents (n = 102) estimating the amount of breastfeeding education offered to their pediatric residents. Residents are provided with a median total of 9.0 hours of breastfeeding training over 3 years, primarily in continuity clinic and in lectures and rounds with attendings. At the programs' primary teaching hospitals, breastfeeding residents are provided breastfeeding rooms (67.0%), breast pumps (75.3%), and breast milk storage facilities (87.6%). Only 10 programs reported having an official policy to accommodate breastfeeding residents. CONCLUSIONS: Pediatric residents receive approximately 3 hours of breastfeeding training per year. In addition, there is less than universal implementation by residency programs of AAP recommendations for supporting breastfeeding in the workplace. Pediatric residency programs should find ways to improve and assess the quality of breastfeeding education and workplace support to better role model this advocacy standard.

Evaluation of housestaff knowledge and perception of competence in palliative symptom management.

PURPOSE: The Accreditation Council for Graduate Medical Education requires that internal medicine (IM) core curricula include end-of-life care and pain management concepts and that fellows in hematology/oncology, pulmonary/critical care, and geriatrics should receive formal instruction and clinical experience in palliative and end-of-life care. We aimed to assess the effectiveness of current teaching methods for housestaff in these fields. METHOD: All of the IM residents, geriatric medicine fellows, hematology/oncology fellows, and pulmonary/critical care fellows from four regional graduate medical education sites were asked to participate in an online survey at the beginning and end of the 2008-2009 academic year. We evaluated seven domains of knowledge of palliative care and pain management with a self-assessment of competence in these areas. We also asked participants to describe their current curriculum and training in palliative medicine. RESULTS: There were 326 e-mailed survey invitations. There were 180 responses for the start-year survey and 102 responses for the end-year survey. All sites were represented in the responses. The only learners to significantly improve their palliative knowledge during a year of training were PGY-1s and PGY-4s. The majority of housestaff surveyed report that their current palliative medicine training is inadequate. The vast majority (84.6%) said a dedicated palliative medicine rotation would be "useful" or "very useful." CONCLUSIONS: Housestaff recognize their lack of experience and training in palliative medicine and are interested in many teaching venues to improve their skills. A more focused curriculum in palliative and end-of-life care is required at both resident and subspecialty fellowship levels.

Dosing of unfractionated heparin in obese patients with venous thromboembolism.

BACKGROUND: Aggressive weight-based dosing guidelines help achieve prompt therapeutic anticoagulation in patients with venous thromboembolism (VTE). While obese patients with VTE face an increased risk of recurrence, physicians typically resist prescribing doses two to three times the usual dose because of concern about bleeding complications. OBJECTIVE: To examine the use of unfractionated heparin in obese patients with VTE at an academic teaching hospital in order to document the extent and pattern of underprescribing in this high-risk patient population. DESIGN: Three-year, cross-sectional consecutive case series. PATIENTS: Adult inpatients with VTE and a body mass index ≥30 kg/m(2) who were treated with unfractionated heparin. MEASUREMENTS: Time to achievement of therapeutic anticoagulation (activated partial thromboplastin time >60 s) and gap between recommended and prescribed heparin doses. RESULTS: Time to attainment of therapeutic anticoagulation exceeded 24 h in 29% of study patients (n = 84) and exceeded 48 h in 14% of patients. In 75 patients (89%), the prescribed bolus dose fell below the recommended dose of 80 units/kg, and in 64 patients (76%) the initial continuous infusion fell more than 100 units/h below--in some cases more than 1000 units/h below--the recommended dose of 18 units/kg/h. There was a significant correlation between time to therapeutic anticoagulation and initial infusion dose (Spearman r = -0.27; p < 0.02). Each decrease of 1 unit/kg/h translated to a delay ranging from about 0.75 h to 1.5 h over the range of prescribed doses (6 to 22 units/kg/h). CONCLUSIONS: A substantial proportion of obese patients treated with unfractionated heparin experienced a delay >24 h in achieving adequate anticoagulation, and the vast majority received an inadequate heparin bolus or initial continuous infusion (or both) according to current dosing guidelines.

Children's drinking water: parental preferences and implications for fluoride exposure.

PURPOSE: The purposes of this study were to: describe children's drinking water sources; determine if any demographic factors are associated with water choice; describe parents' reasons for selecting bottled water; and determine parents' ability to provide enough information about their drinking water for providers to assess children's fluoride exposure. METHODS: Subjects were parents of children 6 months to 15-years-old. A questionnaire was verbally administered in English or Spanish. Chi-square analyses were used to evaluate associations among study variables. RESULTS: Of 194 parents, 134 (69%) gave their children bottled water either exclusively or with tap water. Bottled water use was not significantly associated with the primary source of tap water, parent's education level, or household income. Reasons for giving children bottled water included: fear of contaminants in tap water; taste and/or smell of tap water; and convenience of bottled water. For parents using bottled water, over 65% did not know the brand's fluoride content. CONCLUSIONS: Barriers to an accurate fluoride assessment include frequent bottled water use and parental uncertainty about its fluoride content. By initiating communication with parents and educating them about fluoride sources, health care and dental providers may be able to better evaluate the adequacy of children's fluoride exposure and decide whether fluoride supplementation is necessary.
