Detection of significant vision conditions in children using QuickSee wavefront autorefractor.

PURPOSE: This study evaluated the ability of QuickSee to detect children at risk for significant vision conditions (significant refractive error [RE], amblyopia and strabismus). METHODS: Non-cycloplegic refraction (using QuickSee without and with +2 dioptre (D) fogging lenses) and unaided binocular near visual acuity (VA) were measured in 4- to 12-year-old children. Eye examination findings (VA, cover testing and cycloplegic retinoscopy) were used to determine the presence of vision conditions. QuickSee performance was summarised by area under the receiver operating characteristic curve (AUC), sensitivity and specificity for various levels of RE. QuickSee referral criteria for each vision condition were chosen to maximise sensitivity at a specificity of approximately 85%-90%. Sensitivity and specificity to detect vision conditions were calculated using multiple criteria. Logistic regression was used to evaluate the benefit of adding near VA (6/12 or worse) for detecting hyperopia. A paired t-test compared QuickSee without and with fogging lenses. RESULTS: The mean age was 8.2 (±2.5) years (n = 174). RE ranged up to 9.25 D myopia, 8 D hyperopia, 5.25 D astigmatism and 3.5 D anisometropia. The testability of the QuickSee was 94.3%. AUC was ≥0.92 (excellent) for each level of RE. For the detection of any RE, sensitivity and specificity were 84.2% and 87.3%, respectively, using modified Orinda criteria and 94.5% and 78.2%, respectively, using the American Academy for Pediatric Ophthalmology and Strabismus (AAPOS) guidelines. For the detection of any significant vision condition, the sensitivity and specificity of QuickSee were 81.1% and 87.9%, respectively, using modified Orinda criteria and 93% and 78.6%, respectively, using AAPOS criteria. There was no significant benefit of adding near VA to QuickSee for the detection of hyperopia ≥+2.00 (p = 0.34). There was no significant difference between QuickSee measurements of hyperopic refractive error with and without fogging lenses (difference = -0.09 D; p = 0.51). CONCLUSIONS: QuickSee had high discriminatory power for detecting children with hyperopia, myopia, astigmatism, anisometropia, any significant refractive error or any significant vision condition.

One-year follow-up of clinical convergence measures in children enrolled in the Convergence Insufficiency Treatment Trial-Attention and Reading Trial.

PURPOSE: To assess the long-term stability of clinical measures of convergence (near point of convergence [NPC] and positive fusional vergence [PFV]) in participants enrolled in the Convergence Insufficiency Treatment Trial-Attention and Reading Trial (CITT-ART) who received 16 weeks of office-based vergence/accommodative therapy. METHODS: A total of 310 children, 9-14 years old, with symptomatic convergence insufficiency were enrolled in CITT-ART. Some 270 completed both their 16-week primary outcome visit followed by a 1-year follow-up visit. Of those 270, 181 (67%) were randomised to the vergence/accommodative therapy. Of the 181 in the vergence/accommodative group, 121 (67%) reported not receiving any additional treatment after the 16-week primary outcome visit. The mean change in NPC, PFV and percentages of children classified by the predetermined success criteria of convergence (normal NPC [<6 cm] and/or improved by ≥4 cm; normal PFV [passing Sheard's criterion and base-out break >15Δ] and/or improved by ≥10Δ) were compared at the 16-week primary outcome visit and 1 year later. RESULTS: Of the 121 who returned for their 1-year follow-up visit, there was no significant change in mean adjusted NPC (reduction of -0.2 cm; 95% CI: -1.0 to 0.5 cm) at 1 year. There was a statistically significant decrease in mean-adjusted PFV (-4.7∆; 95% CI: -6.5 to -2.8Δ) at 1 year. There were similar percentages of participants classified as 'normal' (p = 0.30), 'normal and/or improved' (p > 0.50) and 'normal and improved' (p > 0.14) based on NPC and PFV at the 1-year visit compared with the 16-week primary outcome visit. CONCLUSION: The improvements in NPC and PFV following 16 weeks of vergence/accommodative therapy (with no reported additional treatment thereafter) in children with symptomatic convergence insufficiency persisted 1-year post-treatment.

Evaluation of a Pilot Protocol for Detecting Infant Hyperopia.

SIGNIFICANCE: Highly hyperopic children are at greater risk for developing conditions such as strabismus, amblyopia, and early literacy and reading problems. High hyperopia is a common finding in infants in a pediatric medical practice, and early detection can be done effectively in that setting with tropicamide autorefraction. PURPOSE: This study aimed to evaluate the effectiveness of a pilot screening program to detect high hyperopia in 2-month-old infants in a pediatric medical practice in Columbus, Ohio. METHODS: Cycloplegic refractive error (1% tropicamide) was measured by retinoscopy and autorefraction with the Welch Allyn SureSight (Welch Allyn/Hillrom, Skaneateles Falls, NY) in 473 infants (55.4% female) who were undergoing their 2-month well-baby visit at their pediatrician's medical practice. Cycloplegic retinoscopy (1% cyclopentolate) was repeated at a subsequent visit in 35 infants with ≥+5.00 D hyperopia in the most hyperopic meridian during the screening. RESULTS: Twenty-eight infants (5.9%) had high hyperopia (spherical equivalent, ≥+5.00 D), and 61 (12.9%) had high hyperopia (≥+5.00 D in at least one meridian of at least one eye) by retinoscopy with 1% tropicamide. The mean ± standard deviation spherical equivalent tropicamide cycloplegic refractive error measured with retinoscopy was +2.54 ± 1.54 D (range, -3.25 to +7.00 D) and with SureSight was +2.29 ± 1.64 D (range, -2.90 to +7.53 D). Retinoscopy done using 1% cyclopentolate was 0.44 ± 0.54 D more hyperopic in spherical equivalent than with 1% tropicamide ( P < .001). CONCLUSIONS: High hyperopia was a common finding in 2-month-old infants in a pediatric medical setting that could be detected effectively by cycloplegic autorefraction using tropicamide. Greater cooperation between pediatric primary vision and medical care could lead to effective vision screenings designed to detect high hyperopia in infants.

Prescribing patterns for paediatric hyperopia among paediatric eye care providers.

PURPOSE: To survey paediatric eye care providers to identify current patterns of prescribing for hyperopia. METHODS: Paediatric eye care providers were invited, via email, to participate in a survey to evaluate current age-based refractive error prescribing practices. Questions were designed to determine which factors may influence the survey participant's prescribing pattern (e.g., patient's age, magnitude of hyperopia, patient's symptoms, heterophoria and stereopsis) and if the providers were to prescribe, how much hyperopic correction would they prescribe (e.g., full or partial prescription). The response distributions by profession (optometry and ophthalmology) were compared using the Kolmogorov-Smirnov cumulative distribution function test. RESULTS: Responses were submitted by 738 participants regarding how they prescribe for their hyperopic patients. Most providers within each profession considered similar clinical factors when prescribing. The percentages of optometrists and ophthalmologists who reported considering the factor often differed significantly. Factors considered similarly by both optometrists and ophthalmologists were the presence of symptoms (98.0%, p = 0.14), presence of astigmatism and/or anisometropia (97.5%, p = 0.06) and the possibility of teasing (8.3%, p = 0.49). A wide range of prescribing was observed within each profession, with some providers reporting that they would prescribe for low levels of hyperopia while others reported that they would never prescribe. When prescribing for bilateral hyperopia in children with age-normal visual acuity and no manifest deviation or symptoms, the threshold for prescribing decreased with age for both professions, with ophthalmologists typically prescribing 1.5-2 D less than optometrists. The threshold for prescribing also decreased for both optometrists and ophthalmologists when children had associated clinical factors (e.g., esophoria or reduced near visual function). Optometrists and ophthalmologists most commonly prescribed based on cycloplegic refraction, although optometrists most commonly prescribed based on both the manifest and cycloplegic refraction for children ≥7 years. CONCLUSION: Prescribing patterns for paediatric hyperopia vary significantly among eye care providers.

Evaluation and guide for embedding opioid use disorder education in health professions' curricula.

BACKGROUND: Morbidity and mortality from Opioid Use Disorder is a health crisis in the United States. During the COVID-19 pandemic, there was a devastating increase of 38.4% in overdose deaths from the 12-month period leading up to June 2019 compared with the 12-month period leading up to May 2020, primarily driven by synthetic opioids. Buprenorphine is an effective medication for opioid use disorder but uptake is slow due in part to lack of provider knowledge, confidence, and negative attitudes/stigma toward patients with OUD. Addressing these barriers in academic training is a promising approach to building workforce able to effectively treat opioid use disorder. METHODS: Our university developed a training for pre-licensure physicians, physician assistants and psychiatric nurse practitioners that included the DATA Waiver training and a shadowing experience. Expected outcomes included improved knowledge, skills and attitudes about persons with OUD and buprenorphine treatment, plans to provide this treatment post-graduation, for pre-licensure learners to have completed all requirements to prescribe buprenorphine post-graduation, and for the training to be embedded into school's curricula. RESULTS: Results were positive overall including improved knowledge and attitudes toward persons with OUD, better understanding of the benefits of this treatment for patients, increased confidence and motivation to provide this treatment post-graduation. The training is now embedded in each program's graduation requirements. CONCLUSION: Developing a didactic and experiential training on buprenorphine treatment for opioid use disorder and embedding it into medical, physician assistant, and psychiatric nurse practitioner licensure programs can help prepare future providers to treat opioid use disorder in a range of settings. Key to replicating this program in other university settings is to engage faculty members who actively provide treatment to persons with OUD to ensure shadowing opportunities and serve as role models for learners.

Does coexisting accommodative dysfunction impact clinical convergence measures, symptoms and treatment success for symptomatic convergence insufficiency in children?

PURPOSE: To determine whether coexisting accommodative dysfunction in children with symptomatic convergence insufficiency (CI) impacts presenting clinical convergence measures, symptoms and treatment success for CI. METHODS: Secondary data analyses of monocular accommodative amplitude (AA; push-up method), monocular accommodative facility (AF; ±2.00 D lens flippers) and symptoms (CI Symptom Survey [CISS]) in children with symptomatic CI from the Convergence Insufficiency Treatment Trial (N = 218) and CITT-Attention and Reading Trial (N = 302) were conducted. Decreased AA was defined as more than 2D below the minimum expected amplitude for age (15 - » age); those with AA < 5 D were excluded. Decreased AF was defined as <6 cycles per minute. Mean near point of convergence (NPC), near positive fusional vergence (PFV) and symptoms (CISS) were compared between those with and without accommodative dysfunction using analysis of variance and independent samples t-testing. Logistic regression was used to compare the effect of baseline accommodative function on treatment success [defined using a composite of improvements in: (1) clinical convergence measures and symptoms (NPC, PFV and CISS scores) or (2) solely convergence measures (NPC and PFV)]. RESULTS: Accommodative dysfunction was common in children with symptomatic CI (55% had decreased AA; 34% had decreased AF). NPC was significantly worse in those with decreased AA (mean difference = 6.1 cm; p < 0.001). Mean baseline CISS scores were slightly worse in children with coexisting accommodative dysfunction (decreased AA or AF) (30.2 points) than those with normal accommodation (26.9 points) (mean difference = 3.3 points; p < 0.001). Neither baseline accommodative function (p ≥ 0.12 for all) nor interaction of baseline accommodative function and treatment (p ≥ 0.50) were related to treatment success based on the two composite outcomes. CONCLUSIONS: A coexisting accommodative dysfunction in children with symptomatic CI is associated with worse NPC, but it does not impact the severity of symptoms in a clinically meaningful way. Concurrent accommodative dysfunction does not impact treatment response for CI.

Repeatability and Validity of Peripheral Refraction with Two Different Autorefractors.

SIGNIFICANCE: The Welch Allyn SureSight (Welch Allyn, Skaneateles Falls, NY) and Plusoptix PowerRefractor (Plusoptix, Nuremberg, Germany) are often used with infants, but little is known about the repeatability and validity of their peripheral refractive error measurements. Selecting the best instrument will support future refractive error and emmetropization studies. PURPOSE: The purpose of this study was to determine the validity and repeatability of peripheral refractive error measurements and peripheral refraction profiles measured with the Welch Allyn SureSight and Plusoptix PowerRefractor compared with the criterion standard Grand Seiko WR-5100K (Grand Seiko Co., Hiroshima, Japan). METHODS: Cycloplegic (tropicamide 1%) autorefraction was measured in the right eyes of 21 adult subjects (31.4 ± 10.4 years) with the three instruments in randomized order on two separate visits, at least 24 hours apart, centrally, and at 30 and 20° temporal and nasal gaze. RESULTS: The SureSight measurements were within 0.24 D and not significantly different from the Grand Seiko WR-5100K in any gaze (P < .65), whereas the PowerRefractor measurements were more myopic by as much as -0.97 D and significantly different in four of the five gaze directions (P < .04). The 95% limits of agreement between occasions by gaze ranged from ±0.38 to ±0.61 D for the SureSight, similar to or slightly better than the WR-5100K (±0.31 to ±1.51 D) and the PowerRefractor (±0.72 to ±1.71 D). There were no significant differences between visits for any instrument in any gaze (P < .94). The repeatability of the SureSight was also better than that for the Grand Seiko when peripheral refraction was represented by quadratic fits to the data. CONCLUSIONS: These findings suggest that the Welch Allyn SureSight is the most suitable portable autorefractor to use to monitor peripheral autorefraction based on better repeatability between occasions and better validity compared with the criterion standard Grand Seiko WR-5100K.

Effects of Pollution on Marine Organisms.

This review covers selected 2017 articles on the biological effects of pollutants and human physical disturbances on marine and estuarine plants, animals, ecosystems and habitats. The review, based largely on journal articles, covers field and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, marine debris, dredging and disposal etc. Special emphasis is placed on effects of oil spills and marine debris due largely to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and proliferation of data on the assimilation and effects of marine debris microparticulates. Several topical areas reviewed in the past (e.g.mass mortalities ocean acidification) were dropped this year. The focus of this review is on effects, not on pollutant sources, chemistry, fate or transport. There is considerable overlap across subject areas (e.g.some bioaccumulation data may be appear in other topical categories such as effects of wastewater discharges, or biomarker studies appearing in oil toxicity literature). Therefore, we strongly urge readers to use keyword searching of the text and references to locate related but distributed information. Although nearly 400 papers are cited, these now represent a fraction of the literature on these subjects. Use this review mainly as a starting point.

Identification, modeling and ligand affinity of early deuterostome CYP51s, and functional characterization of recombinant zebrafish sterol 14α-demethylase.

BACKGROUND: Sterol 14α-demethylase (cytochrome P450 51, CYP51, P45014DM) is a microsomal enzyme that in eukaryotes catalyzes formation of sterols essential for cell membrane function and as precursors in biosynthesis of steroid hormones. Functional properties of CYP51s are unknown in non-mammalian deuterostomes. METHODS: PCR-cloning and sequencing and computational analyses (homology modeling and docking) addressed CYP51 in zebrafish Danio rerio, the reef fish sergeant major Abudefduf saxatilis, and the sea urchin Strongylocentrotus purpuratus. Following N-terminal amino acid modification, zebrafish CYP51 was expressed in Escherichia coli, and lanosterol 14α-demethylase activity and azole inhibition of CYP51 activity were characterized using GC-MS. RESULTS: Molecular phylogeny positioned S. purpuratus CYP51 at the base of the deuterostome clade. In zebrafish, CYP51 is expressed in all organs examined, most strongly in intestine. The recombinant protein bound lanosterol and catalyzed 14α-demethylase activity, at 3.2nmol/min/nmol CYP51. The binding of azoles to zebrafish CYP51 gave KS (dissociation constant) values of 0.26µM for ketoconazole and 0.64µM for propiconazole. Displacement of carbon monoxide also indicated zebrafish CYP51 has greater affinity for ketoconazole. Docking to homology models showed that lanosterol docks in fish and sea urchin CYP51s with an orientation essentially the same as in mammalian CYP51s. Docking of ketoconazole indicates it would inhibit fish and sea urchin CYP51s. CONCLUSIONS: Biochemical and computational analyses are consistent with lanosterol being a substrate for early deuterostome CYP51s. GENERAL SIGNIFICANCE: The results expand the phylogenetic view of animal CYP51, with evolutionary, environmental and therapeutic implications.

Peripheral Defocus, Pupil Size, and Axial Eye Growth in Children Wearing Soft Multifocal Contact Lenses in the BLINK Study.

Purpose: The purpose of this study was to evaluate the relationship between peripheral defocus and pupil size on axial growth in children randomly assigned to wear either single vision contact lenses, +1.50 diopter (D), or +2.50 D addition multifocal contact lenses (MFCLs). Methods: Children 7 to 11 years old with myopia (-0.75 to -5.00 D; spherical component) and ≤1.00 D astigmatism were enrolled. Autorefraction (horizontal meridian; right eye) was measured annually wearing contact lenses centrally and ±20 degrees, ±30 degrees, and ±40 degrees from the line of sight at near and distance. Photopic and mesopic pupil size were measured. The effects of peripheral defocus, treatment group, and pupil size on the 3-year change in axial length were modeled using multiple variables that evaluated defocus across the retina. Results: Although several peripheral defocus variables were associated with slower axial growth with MFCLs, they were either no longer significant or not meaningfully associated with eye growth after the treatment group was included in the model. The treatment group assignment better explained the slower eye growth with +2.50 MFCLs than peripheral defocus. Photopic and mesopic pupil size did not modify eye growth with the +2.50 MFCL (all P ≥ 0.37). Conclusions: The optical signal causing slower axial elongation with +2.50 MFCLs is better explained by the lens type worn than by peripheral defocus. The signal might be something other than peripheral defocus, or there is not a linear dose-response relationship within treatment groups. We found no evidence to support pupil size as a criterion when deciding which myopic children to treat with MFCLs.

Quality of life of community-residing persons with dementia based on self-rated and caregiver-rated measures.

PURPOSE: To identify correlates of self-rated and caregiver-rated quality of life (QOL) in community-residing persons with dementia (PWD) for intervention development. METHODS: Cross-sectional data of 254 PWD and their caregivers participating in a clinical trial were derived from in-home assessments. Self-rated QOL was measured with the Quality of Life-Alzheimer Disease (QOL-AD) scale, and caregiver-rated QOL was measured using the QOL-AD and Alzheimer Disease-Related Quality of Life (ADRQL) scales. Multivariate modeling identified correlates of the PWD' QOL. RESULTS: Self-rated QOL was related significantly to participant race, unmet needs, depression, and total medications. Caregiver-rated QOL-AD scores were significantly associated with participant function, unmet needs, depression, and health problems and with caregiver burden and self-rated health. Significant correlates of ADRQL scores included neuropsychiatric symptom severity, functional and cognitive impairment, and caregiver burden and depression. CONCLUSIONS: Correlates of QOL in community-residing PWD depend on who rates the PWD's QOL and which measure is used. Addressing health problems, medication use, and dementia-related unmet needs, reducing functional dependency, and treating neuropsychiatric symptoms in PWD, while reducing caregiver burden and depression, may maximize QOL in those with dementia.

Predictors of quality of life ratings for persons with dementia simultaneously reported by patients and their caregivers: the Cache County (Utah) Study.

BACKGROUND: Quality of life (QOL) is frequently assessed in persons with dementia (PWD) through self- and/or proxy-report. Determinants of QOL ratings are multidimensional and may differ between patients and caregiver proxies. This study compared self- and proxy-reported QOL ratings in a population-based study of PWD and their caregivers, and examined the extent to which discrepancies in reports were associated with characteristics of the PWD. METHODS: The sample consisted of 246 patient/caregiver dyads from the initial visit of the Cache County Dementia Progression Study, with both members of the dyad rating PWD QOL. PWD age, gender, cognitive impairment (Mini-Mental State Examination), neuropsychiatric symptoms (Neuropsychiatric Inventory; NPI), dementia severity (Clinical Dementia Rating), medical comorbidities (General Medical Health Rating), and functional impairment (Dementia Severity Rating Scale) were examined as correlates of self- and proxy-reported QOL ratings and the differences between the QOL reports. RESULTS: Self- and proxy-reported PWD QOL ratings were only modestly correlated. Medical comorbidity was associated with self-report whereas NPI was associated with proxy-report. Dementia severity was associated with discrepancies in self- and proxy-report, with worse patient cognition associated with poorer proxy-reported QOL ratings. CONCLUSIONS: PWD self- and proxy-reported QOL ratings are associated with different variables. Discrepancies between PWD and caregiver perceptions of PWD QOL should be recognized, particularly in cases of more severe dementia.

Psychiatry and emergency medicine: medical student and physician attitudes toward homeless persons.

OBJECTIVE: The purpose of the study was to explore changes in medical students' attitudes toward homeless persons during the Psychiatry and Emergency Medicine clerkships. Simultaneously, this study explored attitudes toward homeless persons held by Psychiatry and Emergency Medicine residents and faculty in an attempt to uncover the "hidden curriculum" in medical education, in which values are communicated from teacher to student outside of the formal instruction. METHOD: A group of 79 students on Psychiatry and 66 on Emergency Medicine clerkships were surveyed at the beginning and end of their rotation regarding their attitudes toward homeless persons by use of the Health Professionals' Attitudes Toward the Homeless Inventory (HPATHI). The HPATHI was also administered to 31 Psychiatry residents and faculty and 41 Emergency Medicine residents and faculty one time during the course of this study. RESULTS: For Psychiatry clerks, t-tests showed significant differences pre- and post-clerkship experiences on 2 of the 23 items on the HPATHI. No statistically significant differences were noted for the Emergency Medicine students. An analysis of variance revealed statistically significant differences on 7 out of the 23 survey questions for residents and faculty in Psychiatry, as compared with those in Emergency Medicine. CONCLUSION: Results suggest that medical students showed small differences in their attitudes toward homeless people following clerkships in Psychiatry but not in Emergency Medicine. Regarding resident and faculty results, significant differences between specialties were noted, with Psychiatry residents and faculty exhibiting more favorable attitudes toward homeless persons than residents and faculty in Emergency Medicine. Given that medical student competencies should be addressing the broader social issues of homelessness, medical schools need to first understand the attitudes of medical students to such issues, and then develop curricula to overcome inaccurate or stigmatizing beliefs.

Teaching motivational interviewing skills to third-year psychiatry clerkship students.

BACKGROUND: despite a large percentage of health care costs being related to smoking, obesity, and substance abuse, most physicians are not confident in motivating patients to change health behaviors. Motivational interviewing (MI) is a directive, patient-centered approach for eliciting behavior change. The purpose of this study was to teach students MI skills and assess their confidence and knowledge during the psychiatry clerkship using smoking cessation as the target behavior. METHODS: using a pretest/posttest design, 98 students were given a 10-item questionnaire during the psychiatry clerkship to assess their knowledge and confidence in health behavior change. Students received a 3-hour presentation on the principles of MI and practiced skills through role play. Students were encouraged to utilize these skills with patients. RESULTS: paired t tests results showed significant differences pre- and postclerkship for nine of the 10 items, including the student's confidence in working with patients in the area of smoking cessation. CONCLUSION: students can gain basic knowledge and increased confidence in working with patients for promoting behavioral change, even with a brief session, taught by nonexperts in motivational interviewing theory.

A Descriptive Study of Home Modifications for People with Dementia and Barriers to Implementation.

This study describes home environmental features, safety issues, and health-related modifications in a community dwelling sample of 82 elderly people with dementia. Main barriers to the accessibility of the homes were steps, both inside and outside the house. The majority of the caregivers had made home modifications, which pertained mainly to physical limitations. Home modifications to support cognitive deficits were made to a lesser extent. The main barrier to the implementation of home modifications to accommodate the care recipient's memory loss was skepticism about their usefulness. Regarding the removal of physical barriers, financial constraints were most frequently mentioned.

Effects of pollution on marine organisms.

This review covers selected 2019 articles on the biological effects of pollutants, including human physical disturbances, on marine and estuarine plants, animals, ecosystems, and habitats. The review, based largely on journal articles, covers field, and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing, and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, marine debris, dredging, and disposal.

State mental health policy: statewide implementation of the crisis intervention team program: the Ohio model.

This column discusses ways that states can implement community-based best practices statewide, by using the crisis intervention team (CIT) model as an example. Although state mental health authorities may want to use a top-down approach to ensure uniform, high-quality implementation, programs may be more likely to succeed if they arise as bottom-up, grassroots innovations. Programs like CIT are especially challenging to implement because they involve collaboration between complex systems and affect multiple stakeholders. The column describes lessons learned in Ohio in hopes of assisting other states in implementing this and other innovations.
