Weight gained during treatment predicts 6-month body mass index in a large sample of patients with anorexia nervosa using ensemble machine learning

OBJECTIVE

This study used machine learning methods to analyze data on treatment outcomes from individuals with anorexia nervosa admitted to a specialized eating disorders treatment program.

METHODS

Of 368 individuals with anorexia nervosa (209 adolescents and 159 adults), 160 individuals had data available for a 6-month follow-up analysis. Participants were treated in a 6-day-per-week partial-hospital program. Participants were assessed for eating disorder-specific and non-specific psychopathology. The analyses used established machine learning procedures combined in an ensemble model from support vector machine learning, random forest prediction, and the elastic net regularized regression with an exploration (training; 75%) and confirmation (test; 25%) split of the data.

RESULTS

The models predicting body mass index (BMI) at 6-month follow-up explained a 28.6% variance in the training set (n = 120). The model had good performance in predicting 6-month BMI in the test dataset (n = 40), with predicted BMI significantly correlating with actual BMI (r = .51, p = 0.01). The change in BMI from admission to discharge was the most important predictor, strongly correlating with reported BMI at 6-month follow-up (r = .55). Behavioral variables were much less predictive of BMI outcome. Results were similar for z-transformed BMI in the adolescent-only group. Length of stay was most predictive of weight gain in treatment (r = .56) but did not predict longer-term BMI.

CONCLUSIONS

This study, using an agnostic ensemble machine learning approach in the largest to-date sample of individuals with anorexia nervosa, suggests that achieving weight gain goals in treatment predicts longer-term weight-related outcomes. Other potential predictors, personality, mood, or eating disorder-specific symptoms were relatively much less predictive.

PUBLIC SIGNIFICANCE

The results from this study indicate that the amount of weight gained during treatment predicts BMI 6 months after discharge from a high level of care. This suggests that patients require sufficient time in a higher level of care treatment to meet their specific weight goals and be able to maintain normal weight.

Urinary Incontinence in Primary Care-The Gap Between Recommendations and Real World

IMPORTANCE

Routine screening for urinary incontinence (UI) by primary care providers (PCPs) is recommended.

OBJECTIVES

We aimed to describe the rate of incident UI diagnosed at annual PCP visits, the prevalence of UI in a large primary care population, and estimate the rate of screening for UI during primary care preventive and annual wellness visits. Secondary aims were to describe PCP knowledge and behavior as they relate to UI screening and diagnosis.

STUDY DESIGN

The electronic health record was used to abstract the number of adult female patients seen by PCPs within a regional health system with a diagnosis of UI before our study period and with a new diagnosis over a 2-year period. Additional new diagnoses and screening practices were found on chart review of an additional 824 representative charts. Primary care providers within the health system were surveyed about their screening practices and knowledge about UI.

RESULTS

There were 192,053 women primary care patients seen over 2 years. A total of 5.7% had a UI diagnosis preceding the study period and 3.4% had a UI diagnosis during the study period. A total of 42% of PCPs reported that they screen for UI at least half the time and none were completely satisfied with their ability to screen for UI. Sixteen percent of annual wellness visits had any documentation of screening for UI.

CONCLUSION

In a large primary care population, screening for and detection of UI in women was low.

Reducing Care Overuse in Older Patients Using Professional Norms and Accountability : A Cluster Randomized Controlled Trial

BACKGROUND

Effective strategies are needed to curtail overuse that may lead to harm.

OBJECTIVE

To evaluate the effects of clinician decision support redirecting attention to harms and engaging social and reputational concerns on overuse in older primary care patients.

DESIGN

18-month, single-blind, pragmatic, cluster randomized trial, constrained randomization. (ClinicalTrials.gov: NCT04289753).

SETTING

60 primary care internal medicine, family medicine and geriatrics practices within a health system from 1 September 2020 to 28 February 2022.

PARTICIPANTS

371 primary care clinicians and their older adult patients from participating practices.

INTERVENTION

Behavioral science-informed, point-of-care, clinical decision support tools plus brief case-based education addressing the 3 primary clinical outcomes (187 clinicians from 30 clinics) were compared with brief case-based education alone (187 clinicians from 30 clinics). Decision support was designed to increase salience of potential harms, convey social norms, and promote accountability.

MEASUREMENTS

Prostate-specific antigen (PSA) testing in men aged 76 years and older without previous prostate cancer, urine testing for nonspecific reasons in women aged 65 years and older, and overtreatment of diabetes with hypoglycemic agents in patients aged 75 years and older and hemoglobin A1c (HbA1c) less than 7%.

RESULTS

At randomization, mean clinic annual PSA testing, unspecified urine testing, and diabetes overtreatment rates were 24.9, 23.9, and 16.8 per 100 patients, respectively. After 18 months of intervention, the intervention group had lower adjusted difference-in-differences in annual rates of PSA testing (-8.7 [95% CI, -10.2 to -7.1]), unspecified urine testing (-5.5 [CI, -7.0 to -3.6]), and diabetes overtreatment (-1.4 [CI, -2.9 to -0.03]) compared with education only. Safety measures did not show increased emergency care related to urinary tract infections or hyperglycemia. An HbA1c greater than 9.0% was more common with the intervention among previously overtreated diabetes patients (adjusted difference-in-differences, 0.47 per 100 patients [95% CI, 0.04 to 1.20]).

LIMITATION

A single health system limits generalizability; electronic health data limit ability to differentiate between overtesting and underdocumentation.

CONCLUSION

Decision support designed to increase clinicians' attention to possible harms, social norms, and reputational concerns reduced unspecified testing compared with offering traditional case-based education alone. Small decreases in diabetes overtreatment may also result in higher rates of uncontrolled diabetes.

Association of primary care visit length with outpatient utilization, continuity, and care processes

BACKGROUND

Little is known about how variation in the scheduled length of primary care visits can impact patients' patterns of health care utilization.

OBJECTIVE

To evaluate how the scheduled length of in-person visits with primary care physicians (PCPs) was associated with PCP and patient characteristics, outpatient utilization, and preventive care receipt.

METHODS

This retrospective cohort study examined data from a large American academic health system. PCP visit length template was defined as either 15- and 30-min scheduled appointments (i.e. 15/30), or 20- and 40-min scheduled appointments (i.e. 20/40).

RESULTS

Of 222 included PCPs, 85 (38.3%) used the 15/30 template and 137 (61.7%) used the 20/40 template. The 15/30 group had higher proportions of male (49.4%, vs. 35.8% in the 20/40 group) and family medicine (37.6% vs. 21.2%) physicians. In adjusted patient-level analysis (N = 238,806), having a 15/30 PCP was associated with 9% more primary care visits (incidence rate ratio [IRR], 1.09; 95% confidence interval [CI], 1.03-1.14), and 8% fewer specialty care visits (IRR, 0.92; 95% CI, 0.86-0.98). PCP visit length template was not associated with significant differences in obstetrics/gynaecology visits, continuity of care, or preventive care receipt. In interaction analyses, having a 15/30 PCP was associated with additional primary care visits among non-Hispanic White patients (IRR, 1.10; 95% CI, 1.04-1.16) but not among non-Hispanic Black patients.

CONCLUSION

PCPs' choices about the scheduled length of in-person visits may impact their patients' specialty care use, and have varying impacts across different racial/ethnic groups.

Design and development of microformulations for rapid release of small molecules and oligonucleotides

A systemic delivery of therapeutics frequently results in sub-optimal exposure of the targeted locus and undesired side effects. To address these challenges, a platform for local delivery of diverse therapeutics by remotely controlled magnetic micro-robots was introduced. The approach involves micro-formulation of active molecules using hydrogels that exhibit wide range of loading capabilities and predictable release kinetics. This work introduces two specific hydrogels based on thiol-maleimide and PEG-PLA-diacrylate chemistries that afford high, reliable and reproducible loading and release of several model molecules including doxorubicin, 25-mer poly-dT oligonucleotide and a 5.4 kBp GFP DNA plasmid. The described formulations are suitable for micro-dosing using both conventional or remote delivery devices.

Prevalence and appropriateness of in-person versus not-in-person ambulatory antibiotic prescribing in an integrated academic health system: A cohort study

OBJECTIVES

Ambulatory antibiotic stewardship generally aims to address the appropriateness of antibiotics prescribed at in-person visits. The prevalence and appropriateness of antibiotics prescribed outside of in-person visits is poorly studied.

DESIGN AND SETTING

Retrospective cohort study of all ambulatory antibiotic prescribing in an integrated health delivery system in the United States.

PARTICIPANTS

Antibiotic prescribers and patients receiving oral antibiotic prescriptions between January 2016 and December 2019.

MAIN OUTCOME MEASURES

Proportion of antibiotics prescribed with in-person visits or not-in-person encounters (e.g., telephone, refills). Proportion of prescriptions in in 5 mutually exclusive appropriateness groups: 1) chronic antibiotic use; 2) antibiotic-appropriate; 3) potentially antibiotic-appropriate; 4) non-antibiotic-appropriate; and 5) not associated with a diagnosis.

RESULTS

Over the 4-year study period, there were 714,057 antibiotic prescriptions ordered for 348,739 unique patients by 2,391 clinicians in 467 clinics. Patients had a mean age of 41 years old, were 61% female, and 78% White. Clinicians were 58% women; 78% physicians; and were 42% primary care, 39% medical specialists, and 12% surgical specialists. Overall, 81% of antibiotics were prescribed with in-person visits and 19% without in-person visits. The most common not-in-person encounter types were telephone (10%), orders only (5%), and refill encounters (3%). Of all antibiotic prescriptions, 16% were for chronic use, 15% were antibiotic-appropriate, 39% were potentially antibiotic-appropriate, 22% were non-antibiotic-appropriate, and 8% were not associated with a diagnosis. Antibiotics prescribed in not-in-person encounters were more likely to be chronic (20% versus 15%); less likely to be associated with appropriate or potentially appropriate diagnoses (30% versus 59%) or non-antibiotic-appropriate diagnoses (8% versus 25%); and more likely to be associated with no diagnosis (42% versus <1%).

CONCLUSIONS

Ambulatory stewardship interventions that focus only on in-person visits may miss a large proportion of antibiotic prescribing, inappropriate prescribing, and antibiotics prescribed in the absence of any diagnosis.

Use of Machine Learning and Lay Care Coaches to Increase Advance Care Planning Conversations for Patients With Metastatic Cancer

PURPOSE

Patients with metastatic cancer benefit from advance care planning (ACP) conversations. We aimed to improve ACP using a computer model to select high-risk patients, with shorter predicted survival, for conversations with providers and lay care coaches. Outcomes included ACP documentation frequency and end-of-life quality measures.

METHODS

In this study of a quality improvement initiative, providers in four medical oncology clinics received Serious Illness Care Program training. Two clinics (thoracic/genitourinary) participated in an intervention, and two (cutaneous/sarcoma) served as controls. ACP conversations were documented in a centralized form in the electronic medical record. In the intervention, providers and care coaches received weekly e-mails highlighting upcoming clinic patients with < 2 year computer-predicted survival and no prior prognosis documentation. Care coaches contacted these patients for an ACP conversation (excluding prognosis). Providers were asked to discuss and document prognosis.

RESULTS

In the four clinics, 4,968 clinic visits by 1,251 patients met inclusion criteria (metastatic cancer with no prognosis previously documented). In their first visit, 28% of patients were high-risk (< 2 year predicted survival). Preintervention, 3% of both intervention and control clinic patients had ACP documentation during a visit. By intervention end (February 2021), 35% of intervention clinic patients had ACP documentation compared with 3% of control clinic patients. Providers' prognosis documentation rate also increased in intervention clinics after the intervention (2%-27% in intervention clinics, P < .0001; 0%-1% in control clinics). End-of-life care intensity was similar in intervention versus control clinics, but patients with ≥ 1 provider ACP edit met fewer high-intensity care measures (P = .04).

CONCLUSION

Combining a computer prognosis model with care coaches increased ACP documentation.

Development and pilot testing of EHR-nudges to reduce overuse in older primary care patients

BACKGROUND

Unnecessary testing and treatment of common conditions in older adults can lead to significant morbidity and mortality. The primary objective of this study was to develop and pilot test a set of clinical decision support (CDS) alerts informed by social psychology to address overuse in three areas related to ambulatory care of older adults.

METHODS

We developed three electronic health record (EHR) CDS alerts to address overuse and pilot tested them from January 17, 2019 to July 17, 2019. We enrolled 14 primary care physicians from three practices within a large health system who cared for adults aged 65 years and older. Three measures of overuse applied to patients meeting the following criteria: ordering of prostate-specific antigen (PSA) for prostate cancer screening in adult men aged 76 years and older, ordering of urinalysis or urine cultures (UA or UC) for non-specific reasons to identify bacteriuria in women aged 65 years and older, and overtreatment of diabetes with insulin or oral hypoglycemic medications in adults aged at 75 years and older (DM). Clinicians received CDS alerts when criteria for any of the three overuse measures were met. We then surveyed clinicians to evaluate their experience with the CDS alerts.

RESULTS

The number of clinical encounters that triggered CDS alerts was 19 for PSA, 48 for UA/UC and 128 for DM. For PSA encounters, 4 (21%) orders were not performed after the alert. In the UA/UC encounters 29 (60%) orders were not performed after the alert. For the DM encounters, 21 (34%) had diabetes therapy reduced following the alert. Survey respondents indicated that the alerts were clinically accurate and sometimes led them to change their clinical action.

CONCLUSIONS

These CDS alerts were feasible to implement and may minimize unnecessary testing and treatment of common conditions in older adults.

Temperature-controlled Laminar Airflow (TLA) in symptomatic severe asthma – a post hoc analysis of severe exacerbations, quality of life and health economics

Purpose

Uncontrolled severe asthma constitutes a major economic burden to society. Add-ons to standard inhaled treatments include inexpensive oral corticosteroids and expensive biologics. Nocturnal treatment with Temperature-controlled Laminar Airflow (TLA; Airsonett®) could be an effective, safe and cheaper alternative. The potential of TLA in reducing severe asthma exacerbations was addressed in a recent randomised placebo-controlled trial (RCT) in patients with severe asthma (Global Initiative for Asthma (GINA) step 4/5), but the results were inconclusive. We re-analysed the RCT with severe exacerbations stratified by the level of baseline asthma symptoms and Quality of Life.

Methods

More uncontrolled patients, defined by Asthma Control Questionnaire 7 (ACQ7) > 3, EuroQoL 5-Dimension Questionnaire Visual Analogue Scale (EQ5D-VAS) ≤ 65 and Asthma Quality of Life Questionnaire (AQLQ) ≤ 4 were selected for re-analysis. The rates of severe asthma exacerbations, changes in QoL and health-economics were analysed and compared between TLA and placebo.

Results

The study population included 226 patients (113 TLA / 113 placebo.) The rates of severe asthma exacerbations were reduced by 33, 31 and 25% (p = 0.083, 0.073, 0.180) for TLA compared to placebo, dependent on selected control measures (ACQ7, EQ5D-VAS, AQLQ, respectively). For patients with less control defined by AQLQ≤4, the difference in mean AQLQ0-12M between TLA and placebo was 0.31, 0.33, 0.26 (p = 0.085, 0.034, 0.150), dependent on selected covariate (AQLQ, EQ5D-VAS, ACQ7, respectively). For patients with poor control defined by ACQ7 > 3, the difference in EQ5D-5 L utility scores between TLA and placebo was significant at 9 and 12 months with a cost-effective ICER. The results from the original study did not demonstrate these differences.

Conclusion

This post hoc analysis demonstrated an effect of TLA over placebo on severe exacerbations, asthma control and health economics in a subgroup of patients with more symptomatic severe allergic asthma. The results are consistent with the present recommendations for TLA. However, these differences were not demonstrated in the full study. Several explanations for the different outcomes have been outlined, which should be addressed in future studies.

Look-Back and Look-Forward Durations and the Apparent Appropriateness of Ambulatory Antibiotic Prescribing

Ambulatory antibiotic stewards, researchers, and performance measurement programs choose different durations to associate diagnoses with antibiotic prescriptions. We assessed how the apparent appropriateness of antibiotic prescribing changes when using different look-back and look-forward periods. Examining durations of 0 days (same-day), -3 days, -7 days, -30 days, ±3 days, ±7 days, and ±30 days, we classified all ambulatory antibiotic prescriptions in the electronic health record of an integrated health care system from 2016 to 2019 (714,057 prescriptions to 348,739 patients by 2391 clinicians) as chronic, appropriate, potentially appropriate, inappropriate, or not associated with any diagnosis. Overall, 16% percent of all prescriptions were classified as chronic infection related. Using only same-day diagnoses, appropriate, potentially appropriate, inappropriate, and not-associated antibiotics, accounted for 14%, 36%, 22%, and 11% of prescriptions, respectively. As the duration of association increased, the proportion of appropriate antibiotics stayed the same (range, 14% to 18%), potentially appropriate antibiotics increased (e.g., 43% for -30 days), inappropriate stayed the same (range, 22% to 24%), and not-associated antibiotics decreased (e.g., 2% for -30 days). Using the longest look-back-and-forward duration (±30 days), appropriate, potentially appropriate, inappropriate, and not-associated antibiotics, accounted for 18%, 44%, 20%, and 2% of prescriptions, respectively. Ambulatory programs and studies focused on appropriate or inappropriate antibiotic prescribing can reasonably use a short duration of association between an antibiotic prescription and diagnosis codes. Programs and studies focused on potentially appropriate antibiotic prescribing might consider examining longer durations.

A Qualitative Description of Clinician Free-Text Rationales Entered within Accountable Justification Interventions

BACKGROUND

Requiring accountable justifications-visible, clinician-recorded explanations for not following a clinical decision support (CDS) alert-has been used to steer clinicians away from potentially guideline-discordant decisions. Understanding themes from justifications across clinical content areas may reveal how clinicians rationalize decisions and could help inform CDS alerts.

METHODS

We conducted a qualitative evaluation of the free-text justifications entered by primary care physicians from three pilot interventions designed to reduce opioid prescribing and, in older adults, high-risk polypharmacy and overtesting. Clinicians encountered alerts when triggering conditions were met within the chart. Clinicians were asked to change their course of action or enter a justification for the action that would be displayed in the chart. We extracted all justifications and grouped justifications with common themes. Two authors independently coded each justification and resolved differences via discussion. Three physicians used a modified Delphi technique to rate the clinical appropriateness of the justifications.

RESULTS

There were 560 justifications from 50 unique clinicians. We grouped these into three main themes used to justify an action: (1) report of a particular diagnosis or symptom (e.g., for "anxiety" or "acute pain"); (2) provision of further contextual details about the clinical case (e.g., tried and failed alternatives, short-term supply, or chronic medication); and (3) noting communication between clinician and patient (e.g., "risks and benefits discussed"). Most accountable justifications (65%) were of uncertain clinical appropriateness.

CONCLUSION

Most justifications clinicians entered across three separate clinical content areas fit within a small number of themes, and these common rationales may aid in the design of effective accountable justification interventions. Justifications varied in terms of level of clinical detail. On their own, most justifications did not clearly represent appropriate clinical decision making.

Development of High-Risk Geriatric Polypharmacy Electronic Clinical Quality Measures and a Pilot Test of EHR Nudges Based on These Measures

BACKGROUND

Inappropriate polypharmacy, prevalent among older patients, is associated with substantial harms.

OBJECTIVE

To develop measures of high-risk polypharmacy and pilot test novel electronic health record (EHR)-based nudges grounded in behavioral science to promote deprescribing.

DESIGN

We developed and validated seven measures, then conducted a three-arm pilot from February to May 2019.

PARTICIPANTS

Validation used data from 78,880 patients from a single large health system. Six physicians were pre-pilot test environment users. Sixty-nine physicians participated in the pilot.

MAIN MEASURES

Rate of high-risk polypharmacy among patients aged 65 years or older. High-risk polypharmacy was defined as being prescribed ≥5 medications and satisfying ≥1 of the following high-risk criteria: drugs that increase fall risk among patients with fall history; drug-drug interactions that increase fall risk; thiazolidinedione, NSAID, or non-dihydropyridine calcium channel blocker in heart failure; and glyburide, glimepiride, or NSAID in chronic kidney disease.

INTERVENTIONS

Physicians received EHR alerts when renewing or prescribing certain high-risk medications when criteria were met. One practice received a "commitment nudge" that offered a chance to commit to addressing high-risk polypharmacy at the next visit. One practice received a "justification nudge" that asked for a reason when high-risk polypharmacy was present. One practice received both.

KEY RESULTS

Among 55,107 patients 65 and older prescribed 5 or more medications, 6256 (7.9%) had one or more high-risk criteria. During the pilot, the mean (SD) number of nudges per physician per week was 1.7 (0.4) for commitment, 0.8 (0.5) for justification, and 1.9 (0.5) for both interventions. Physicians requested to be reminded to address high-risk polypharmacy for 236/833 (28.3%) of the commitment nudges and acknowledged 441 of 460 (95.9%) of justification nudges, providing a text response for 187 (40.7%).

CONCLUSIONS

EHR-based measures and nudges addressing high-risk polypharmacy were feasible to develop and implement, and warrant further testing.

Gay Community Involvement and Condomless Anal Sex Among Sexual Minority Men in the USA

Sexual minority men (SMM) remain disproportionately burdened by sexually transmitted infections. Although gay community involvement has been theorized to be protective against many negative health outcomes, research examining the association between community involvement and condomless anal sex (CAS) has yielded conflicting results. The current study, conducted between 2018-2020, examined whether the importance one places on various aspects of community involvement was associated with CAS among a sample of young adult SMM aged 18-34 years with body image concerns (N = 180). Gay community involvement was measured using the Importance of Gay Community Scale, and the results of an exploratory factor analysis indicated the presence of two factors: "social activism" and "going out/nightlife." A zero-inflated Poisson regression was conducted to examine the association between gay "social activism," "going out/nightlife," and their interaction with the number of CAS partners. Upon examining a significant interaction, "social activism" had a protective effect against CAS at low levels of "going out/nightlife," but this effect was non-significant at higher levels. These results suggest that encouraging gay community involvement through activism could be effective at reducing CAS and addressing the health disparity that exists within this population.

"It closes the gap when the ball is dropped": patient perspectives of a novel smartphone app for regional care coordination after hospital encounters

BACKGROUND

Despite the broad adoption of electronic health records (EHRs) for inpatient and outpatient care, and wide availability of EHR-linked portals, these tools are not always effective in informing primary care teams about patients' emergency department (ED) visits or inpatient admissions, leading to persistent gaps in care coordination. The objective of this study was to understand how patients with limited patient portal use in a safety net setting engaged with a smartphone app that used location tracking to detect and notify care teams about patients' hospital use in order to stimulate care coordination and follow-up care.

METHODS

We recruited English- and Spanish-speaking adults at high risk of hospital use from a Federally Qualified Health Center (FQHC). The app detected when patients visited the hospital and asked them to confirm a hospital visit. When confirmed, the app notified the primary care team about the visit, and the care team followed up with patients according to the FQHC protocols for care coordination. We collected qualitative data on app experience from participants who used the app for four months and used a general inductive approach to identify recurring themes.

RESULTS

Participants generally reported a positive app experience, as it helped solve the problem of poor follow-up care. "I liked the goal of the app…Ultimate goal of it was comforting", recounted one participant when describing her app experience. Participants thought the app push notifications could be refined and the app itself could be modernized. Participants also suggested improvements to the push notifications they received from the app and the visit information they entered into the app for care teams to receive. Some participants also suggested improvements to the FQHC's care coordination workflows facilitated by the app, like an immediate connection to the patient's primary care team.

CONCLUSIONS

The app was well received by low-income patients at high risk of ED/inpatient visits. Future research is needed to determine feasibility of implementation in other settings.

Design of Behavioral Economic Applications to Geriatrics Leveraging Electronic Health Records (BEAGLE): A pragmatic cluster randomized controlled trial

BACKGROUND

Overtesting and treatment of older patients is common and may lead to harms. The Choosing Wisely campaign has provided recommendations to reduce overtesting and overtreatment of older adults. Behavioral economics-informed interventions embedded within the electronic health record (EHR) have been shown to reduce overuse in several areas. Our objective is to conduct a parallel arm, pragmatic cluster-randomized trial to evaluate the effectiveness of behavioral-economics-informed clinical decision support (CDS) interventions previously piloted in primary care clinics and designed to reduce overtesting and overtreatment in older adults.

METHODS/DESIGN

This trial has two parallel arms: clinician education alone vs. clinician education plus behavioral-economics-informed CDS. There are three co-primary outcomes for this trial: (1) prostate-specific antigen (PSA) screening in older men, (2) urine testing for non-specific reasons in older women, and (3) overtreatment of diabetes in older adults. All eligible primary care clinics from a large regional health system were randomized using a modified constrained randomization process and their attributed clinicians were included. Clinicians were recruited to complete a survey and educational module. We randomized 60 primary care clinics with 374 primary care clinicians and achieved adequate balance between the study arms for prespecified constrained variables. Baseline annual overuse rates for the three co-primary outcomes were 25%, 23%, and 17% for the PSA, urine, and diabetes measures, respectively.

DISCUSSION

This trial is evaluating behavioral-economics-informed EHR-embedded interventions to reduce overuse of specific tests and treatments for older adults. The study will evaluate the effectiveness and safety of these interventions.

Temperament-based treatment for young adults with eating disorders: acceptability and initial efficacy of an intensive, multi-family, parent-involved treatment

BACKGROUND

Adult eating disorder treatments are hampered by lack of access and limited efficacy. This open-trial study evaluated the acceptability and preliminary efficacy of a novel intervention for adults with eating disorders delivered to young adults and parent-supports in an intensive, multi-family format (Young Adult Temperament-Based Treatment with Supports; YA-TBT-S).

METHODS

38 YA-TBT-S participants (m age = 19.58; SD 2.13) with anorexia nervosa (AN)-spectrum disorders, bulimia nervosa (BN)-spectrum disorders, and avoidant/restrictive food intake disorder (ARFID) completed self-report assessments at admission, discharge, and 12-month follow-up. Assessments measured program satisfaction, eating disorder psychopathology and impairment, body mass index (BMI), and trait anxiety. Outcomes were analyzed using linear mixed effects models to examine changes in outcome variables over time.

RESULTS

Treatment was rated as highly satisfactory. 53.33% were in partial or full remission at 12-month follow-up. 56% of participants received other treatment within the 12-month follow-up period, suggesting that YA-TBT-S may be an adjunctive treatment. Participants reported reductions in ED symptomatology (AN and BN), increases in BMI (AN and ARFID), and reductions in clinical impairment (AN and ARFID) at 12-month follow-up.

CONCLUSIONS

YA-TBT-S is a feasible and acceptable adjunctive treatment for young adults with a broad range of ED diagnoses and may be a method for involving parents in ED treatment in ways that are acceptable to both parents and YA. Further evaluation of efficacy is needed in larger samples, and to compare YA-TBT-S to other ED treatment approaches. Plain English summary Eating disorders are costly and dangerous psychiatric disorders that affect millions of individuals each year. Despite their risks and societal costs, currently available treatments are limited. This study examined the acceptability and efficacy of Young Adult, Temperament-Based Treatment with Supports (YA-TBT-S), a new treatment program for adults with eating disorders. YA-TBT-S was rated highly, and a significant portion of participants improved based on ratings collected 12 months after program participation. Those with anorexia nervosa (AN) and bulimia nervosa (BN) showed significant reductions in eating disorder pathology, and those with AN and avoidant/restrictive food intake disorder (ARFID) showed increases in BMI over time.

Pathways to Child Abuse Prevention: Seeking and Embedding Public Opinion

Child abuse and neglect is a perplexing public health, human rights, and social justice issue that persists at unacceptable levels. This qualitative survey, involving brief oral conversations (n = 721) about perceptions of child abuse and neglect and its solutions, was drawn from a randomized telephone survey of residents in two U.S. communities. The study focused on two research questions: (a) individual and collective actions that would give child abuse and neglect prevention the best chance for success and (b) what participants would expect to see in a local child abuse prevention effort to have faith in its effectiveness. Participants were mostly female (61%), with the average age of 55.7 years, and had a median income of US$35,000 to US$49,000. Thirty-one percent identified as mandatory reporters and 76% were a primary caregiver for a child at some point in their lives. Thematic analysis identified six themes and one subtheme for the first research question and four themes for the second research question. Participants emphasized the importance of awareness raising, education, broad public support and the value of a locally developed plan, credible leadership, and reliable follow-through. Participants' beliefs and recommendations were mapped to existing and promising child abuse prevention frameworks and implications for prevention planning are outlined.

Examining primary care physician rationale for not following geriatric choosing wisely recommendations

Background

The objective is to understand why physicians order tests or treatments in older adults contrary to published recommendations.

Methods

Participants: Physicians above the median for ≥ 1 measures of overuse representing 3 Choosing Wisely topics. Measurements: Participants evaluated decisions in a semi-structured interview regarding: 1) Screening men aged ≥ 76 with prostate specific antigen 2) Ordering urine studies in women ≥ 65 without symptoms 3) Overtreating adults aged ≥ 75 with insulin or oral hypoglycemic medications. Two investigators independently coded transcripts using qualitative analysis.

Results

Nineteen interviews were conducted across the three topics resulting in four themes. First, physicians were aware and knowledgeable of guidelines. Second, perceived patient preference towards overuse influenced physician action even when physicians felt strongly that testing was not indicated. Third, physicians overestimated benefits of a test and underemphasized potential harms. Fourth, physicians were resistant to change when patients appeared to be doing well.

Conclusions

Though physicians expressed awareness to avoid overuse, deference to patient preferences and the tendency to distort the chance of benefit over harm influenced decisions to order testing. Approaches for decreasing unnecessary testing must account for perceived patient preferences, make the potential harms of overtesting salient, and address clinical inertia among patients who appear to be doing well.

Characteristics of Restart a Heart 2019 event locations in the UK

Introduction

Restart a Heart (RSAH) is an annual CPR mass training initiative delivered predominantly by ambulance services in the UK. The aim of this study was to identify to what extent voluntary participation in the 2019 initiative delivered training to the population with the highest need.

Methods

A cross-sectional observational study of location characteristics for RSAH training events conducted by UK ambulance services. Descriptive statistics were used to analyse event and area characteristics. National cardiac arrest registry data were used to establish proportions of training coverage in “hot spot” areas with above national median incidence of cardiac arrest and below median bystander CPR rates. The significance of observed differences were tested using chi-square for proportions and t-test for means.

Results

Twelve of 14 UK ambulance services participated, training 236,318 people. Most of the events (82%) were held in schools, and schoolchildren comprised most participants (81%). RSAH events were held in areas that were less densely populated (p < 0.001), were more common in affluent areas (p < 0.001), and had a significantly lower proportion of black residents (p < 0.05) and higher proportion of white residents (p < 0.05). Events were held in 28% of known “hot spot” areas in England.

Conclusion

With mandatory CPR training for school children in England, Scotland and Wales there is an opportunity to re-focus RSAH resources to deliver training for all age groups in OHCA “hot spots”, communities with higher proportions of black residents, and areas of deprivation. In Northern Ireland, we recommend targeting schools in areas with similar characteristics.

Appropriateness of Antibiotic Prescribing for Acute Sinusitis in Primary Care: A Cross-sectional Study

The proportion of sinusitis visits that meet antibiotic prescribing criteria is unknown. Of 425 randomly selected sinusitis visits, 50% (214) met antibiotic prescribing criteria. There was no significant difference in antibiotic prescribing at visits that did (205/214 [96%]) and did not (193/211 [92%]; P = .07) meet antibiotic prescribing criteria.

Implementation of Community-Based Resource Referrals for Cardiovascular Disease Self-Management

PURPOSE

Describe primary care practices' implementation of CommunityRx-H3, a community resource referral intervention that utilized practice facilitators to support cardiovascular disease (CVD) prevention quality improvement.

METHODS

Qualitative focus groups were conducted with practice facilitators to elicit perceptions of practices' experiences with CommunityRx-H3, practice-level factors affecting, and practice facilitator strategies to promote implementation. Qualitative data were analyzed using directed content analysis. The Consolidated Framework for Implementation Research was applied deductively to organize and interpret findings.

RESULTS

Fourteen of all 19 practice facilitators participated. Practice facilitators perceived that staff attitudes about connecting patients to community resources for CVD were largely positive. Practices were already using a range of non-systematic strategies to refer to community resources. Practice-level factors that facilitated CommunityRx-H3 implementation included clinician "champions," engaged practice managers, and a practice culture that valued community resources. Implementation barriers included a practice's unwillingness to integrate the intervention into existing workflows, limited staff capacity to complete the resource inventory, and unavailability or cost of materials needed to print the resource referral list ("HealtheRx-H3"). Practice facilitator strategies to promote implementation included supporting ongoing customization of the HealtheRx-H3 and material support. Practice facilitators felt implementation would be improved by integration of CommunityRx-H3 with electronic medical record workflows and alternative methods for engaging practices in the implementation process.

CONCLUSIONS

Practice facilitators are increasingly being utilized by primary care practices to support quality improvement interventions and, as shown here, can also play an important role in implementation science. This study yields insights to improve implementation of community resource referral solutions to support primary care CVD prevention efforts.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Clinician-Level Variation in Three Measures Representing Overuse Based on the American Geriatrics Society Choosing Wisely Statement

IMPORTANCE

The extent of clinician-level variation in the overuse of testing or treatment in older adults is not well understood.

OBJECTIVE

To examine clinician-level variation for three new measures of potentially inappropriate use of medical services in older adults.

DESIGN

Retrospective analysis of overall means and clinician-level variation in performance on three new measures.

SUBJECTS

Adults aged 65 years and older who had office visits with outpatient primary or immediate care clinicians within a single academic medical center health system between July 1, 2016, and June 30, 2017.

MEASURES

Two electronic clinical quality measures representing potentially inappropriate use of medical services in older adults: prostate-specific antigen testing against guidelines (PSA) in men aged 76 and older; urinalysis or urine culture for non-specific reasons in women aged 65 and older; and one intermediate outcome measure: hemoglobin A1c less than 7.0 in adults aged 75 and older with diabetes mellitus treated with insulin or oral hypoglycemic medication.

RESULTS

Sixty-nine clinicians and 2009 patients contributed observations to the PSA measure, 144 clinicians and 5933 patients contributed to the urinalysis/urine culture measure, and 42 clinicians and 665 patients contributed to the diabetes measure. Meaningful clinician-level performance variation was greatest for the PSA measure (intraclass correlation coefficient [ICC] = 0.27), followed by the urinalysis/urine culture measure (ICC = 0.18), and the diabetes measure (ICC = 0.024). The range of possible overuse across clinician quartiles was 8-54% for the PSA measure, 3-35% for the urinalysis/urine culture measure, and 13-49% for the diabetes measure. The odds ratios of overuse in the highest quartile compared with the lowest for the PSA, urinalysis/urine culture, and diabetes measures were 99.3 (95% CI 43 to 228), 15.7 (10 to 24), and 6.0 (3.3 to 11), respectively.

CONCLUSIONS

Within the same health system, rates of potential overuse in elderly patients varied greatly across clinicians, particularly for the process measures examined.

Vancouver's inner-city youth: New approaches for a changing demographic

Introduction

Inner-city youth suffer a high burden of mental illness and seek health care on an episodic basis (McCreary, 2001).

These youth tend to receive limited support services due to a lack of continuity of care as they move from child to adult services. Other barriers include homelessness and substance use.

The Vancouver Inner City Youth Mental Health Program (ICYMHP) is a psychiatry led initiative to provide psychiatric services and further collaboration between inner-city youth agencies providing care to at risk youth.

Aims

To introduce and review a collaborative model of care between psychiatric services and community based organizations.

To review the demographics, presentations and outcomes of youth assessed through the ICYMHP.

Methods

A chart review of all clients assessed through the program from its inception (November 2007) to May 2009 (18 months).

Results

Results from clients seen between November 2007 and June 2008 indicate an incidence of psychosis of 40% in men and 21% in women. Mood disorders were the primary diagnosis in 18% of men and 29% of women. Active substance misuse is high (71% of men, cannabis as drug of choice; 54% of women, methamphetamine as drug of choice). Length of stay at Covenant House nearly tripled for those under the care of the ICYMH versus the general shelter population, a positive outcome (21 days versus 9).

Conclusions

Inner-city homeless youth suffer from a high burden of mental illness. A collaborative model of care exists to improve health care quality and delivery to this population.

Introduction of an enhanced recovery protocol into a laparoscopic living donor nephrectomy programme

INTRODUCTION

Living-donor renal transplantation is the optimal treatment for patients with end-stage renal disease. The rate of living donation in the UK is sub-optimal, and potential donor concerns regarding postoperative recovery may be contributory. Enhanced recovery programmes are well described for a number of surgical procedures, but experience in living-donor surgery is sparse. This study reports the impact of introducing an enhanced recovery protocol into a living-donor renal transplant programme.

MATERIALS AND METHODS

All consecutive patients undergoing laparoscopic living-donor nephrectomy over a 25-month period were included. The principles of enhanced recovery were fluid restriction, morphine sparing and expectation management. Outcome measures were postoperative pain scores and complications for donor and recipients.

RESULTS

Standard care was provided for 24 (30%) patients and 57 (70%) followed an enhanced recovery pathway. The latter group received significantly less preoperative intravenous fluid (0ml vs 841ml p < 000.1) and opiate medication (14.83mg vs 23.85mg p = 0.001). Pain scores, postoperative complications and recipient transplant outcomes were comparable in both groups.

CONCLUSIONS

Enhanced recovery for living-donor nephrectomy is a safe approach for donors and recipients. Application of these techniques and further refinement should be pursued to enhance the experience of living donors.

Associations Between Health Literacy and Medication Self-Management Among Community Health Center Patients with Uncontrolled Hypertension

PURPOSE

Examine associations between health literacy and several medication self-management constructs among a population of adults with uncontrolled hypertension.

PATIENTS AND METHODS

Cross-sectional study of health center patients from the Chicago area with uncontrolled hypertension enrolled between April 2012 and February 2015. Medication self-management constructs-applied to hypertension medications, chronic condition medications and all medications-included: 1) medication reconciliation, 2) knowledge of drug indications, 3) understanding instructions and dosing, and 4) self-reported adherence over 4 days (no missed doses). We determined associations between health literacy and self-management outcomes using multivariable generalized linear regression.

RESULTS

There were 1460 patients who completed screening interviews; 62.9% enrolled and had complete baseline data collected, and were included in the analysis. Of 919 participants, 47.4% had likely limited (low), 33.2% possibly limited, and 19.4% likely adequate health literacy. Compared to participants with likely adequate health literacy, participants with low health literacy were less likely to have chronic medications reconciled (18.0% versus 29.6%, p=0.007), know indications for chronic medications (64.1% versus 83.1%, p<0.001), and demonstrate understanding of instructions and dosing (68.1% versus 82.9%, p=0.001). Self-reported adherence to hypertension medications was higher among the low health literacy group (65.6% versus 56.0%, p=0.010). In multivariable models, health literacy was strongly associated with knowledge of drug indications, and understanding of instructions and dosing.

CONCLUSION

Low health literacy was associated with worse medication self-management in several domains. However, non-adherence was greatest in the most health literate in unadjusted analysis. Among a population of patients with uncontrolled hypertension, the drivers of poor control may vary by health literacy.

Using Electronic Health Records to Measure Quality Improvement Efforts: Findings from a Large Practice Facilitation Initiative

BACKGROUND

Federal incentives for electronic health record (EHR) use typically require quality measure reporting over calendar year or 90-day periods. However, required reporting periods may not align with time frames of real-world quality improvement (QI) efforts. This study described primary care practices' ability to obtain measures with reporting periods aligning with a large QI initiative.

METHODS

Researchers conducted a substudy of a randomized trial testing practice facilitation strategies for preventive cardiovascular care. Three quality measures (aspirin for ischemic vascular disease; blood pressure control for hypertension; smoking screening/cessation) were collected quarterly over one year. The primary outcome was a binary indicator of whether a practice facilitator obtained all three measures with "rolling 12-month" reporting periods (that is, the year preceding each study quarter).

RESULTS

The study included 107 practices, 63 (58.9%) of which met the primary outcome of obtaining all measures with rolling 12-month reporting periods. Smaller practices were less likely to meet the primary outcome (p < 0.001). Practices used 11 different EHRs, 3 of which were unable to consistently produce rolling 12-month measures; at 33 practices (30.8%) using these 3 EHRs, facilitators met a secondary outcome of obtaining prior calendar year and rolling 3-month measures. Facilitators reported barriers to data collection such as practices lacking optional EHR features, and EHRs' inability to produce reporting periods across two calendar years.

CONCLUSION

EHR vendors' compliance with federal reporting requirements is not necessarily sufficient to support real-world QI work. Improvements are needed in the flexibility and usability of EHRs' quality measurement functions, particularly for smaller practices.
