Actual vs Documented Advance Care Planning in a Primary Care Clinic.

Introduction: Advance care planning (ACP) is a complex and multifaceted entity that has significant impact on patient care. ACP takes many forms, may be underbilled, and can have significant ramifications on quality care metrics. We performed a retrospective chart review for patients over 70 years in age in our family medicine resident clinic to evaluate the ways in which ACP is charted and the gap between billed and nonbilled ACP. Methods: The first 50 patients over 70 years in age seen between August 25, 2020 and September 25, 2020 were selected for standardized chart review. Billing for ACP was defined as Current Procedural Terminology codes=-10 codes 99497 or 99498. Primary outcomes were the percentage of patients with ACP and incidence of ACP documents. Secondary outcome was the proportion of documented ACP conversations in office visits which had billing for ACP. Results: Forty-eight patients over 70 years in age were identified with an average age of 80.9 years old. Forty-one of 48 patients (85.4%) had some form of ACP and 12 (25%) had formal ACP documents. Of 25 patients with documented ACP conversations in office visits, eleven patients (44%) had ACP which had been formally billed. Conclusion: The majority of our patients had some form of ACP ranging from inpatient discussions of code status to outpatient visits regarding end-of-life care. However, ACP was underbilled in our practice. Physicians are often evaluated based on quality care metrics such as billed ACP which may not accurately reflect the work physicians are doing.

A Student Telephone Intervention for Primary Care Patient Safety During the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVES: During the COVID-19 pandemic, medical students were unable to participate in clinical learning for several weeks. Many primary care patients no-showed to appointments and did not receive care. We implemented a telephone outreach program using medical students to call primary care patients who no-showed to appointments and did not receive care. METHODS: A brief plan-do-study-act cycle was used to establish protocols and supervision for the phone calls. RESULTS: In the first 5 weeks, of 3,274 scheduled patients there were 426 no-shows; 309 received outreach from students. We developed protocols for supervision, routing, and triage. CONCLUSION: It is feasible and educationally valuable to collaborate with students to reach patients who are at home due to the pandemic. Other practices could adapt this tool in similar situations.

Palliative Care Consultation Reduces Heart Failure Transitions: A Matched Analysis.

Background Palliative care supports quality of life, symptom control, and goal setting in heart failure (HF) patients. Unlike hospice, palliative care does not restrict life-prolonging therapy. This study examined the association between palliative care during hospitalization for HF on the subsequent transitions and procedures. Methods and Results Veterans admitted to hospitals with HF from 2010 to 2015 were randomly selected for the Veterans Administration External Peer Review Program. Variables pertaining to demographic, clinical, laboratory, and usage were captured from Veterans Administration electronic records. Patients receiving hospice services before admission were excluded. Patients who received palliative care were propensity matched to those who did not. The primary outcomes were whether the patient experienced transitions or procedures in the 6 months after admission. Transitions included multiple readmissions (≥2) or intensive care admissions and procedures included mechanical ventilation, pacemaker implantation, or defibrillator implantation. Among 57 182 hospitalized HF patients, 1431 received palliative care, and were well matched to 1431 without (standardized mean differences ≤ ±0.05 on all matched variables). Palliative care was associated with significantly fewer multiple rehospitalizations (30.9% versus 40.3%, P<0.001), mechanical ventilation (2.8% versus 5.4%, P=0.004), and defibrillator implantation (2.1% versus 3.6%, P=0.01). After adjustment for facility fixed effects, palliative care consultation was associated with a significantly reduced hazard of multiple readmissions (adjusted hazard ratio=0.73, 95% CI, 0.64-0.84) and mechanical ventilation (adjusted hazard ratio=0.76, 95% CI, 0.67-0.87). Conclusions Palliative care during HF admissions was associated with fewer readmissions and less mechanical ventilation. When available, engagement of HF patients and caregivers in palliative care for symptom control, quality of life, and goals of care discussions may be associated with reduced rehospitalizations and mechanical ventilation.

Do young female dancers improve symptoms and return to dancing after periacetabular osteotomy for the treatment of symptomatic hip dysplasia?

Although preservation of high activity level has been reported in active young patients after periacetabular osteotomy (PAO) for the treatment of symptomatic hip dysplasia, there is limited evidence whether a dancer may be able to resume dancing after PAO. We asked whether female dancers experience improvement in pain and sports-related activities and return to dance following PAO. Between 1997 and 2014 we performed a total of 44 PAOs in 33 female dancers with symptomatic hip dysplasia. The mean age was 20.3 years (SD 5.6 years) and the median follow-up was 2.7 years (IQR 1.7-5.9 years). The Hip Disability and Osteoarthritis Outcome Score (HOOS), the modified Harris hip score (MHHS) and hip motion were collected preoperatively and at most recent follow-up. Return to dance was recorded from self-reported questionnaires and medical record review. Female dancers reported an improvement in HOOS total scores of nearly 20 points (P = 0.007) and MHHS improved over 17 points (P = 0.01) from preoperative to most-recent follow-up. Out of the 30 patients for whom information about return to dance was available, 19 (63%; 95% CI = 43.9-79.5%) had returned to dance at an average of 8.8 months (±3.6 months) after PAO. With the numbers available we did not identify any factors associated with returning to dance in this cohort. Improvement in hip pain, sports-related activities and hip function may be expected following PAO in young female dancers. Most female dancers can expect to return to dance during the first year after surgery.

A Multivariable Prediction Model for Mortality in Individuals Admitted for Heart Failure.

OBJECTIVES: To derive and validate a 30-day mortality clinical prediction rule for heart failure based on admission data and prior healthcare usage. A secondary objective was to determine the discriminatory function for mortality at 1 and 2 years. DESIGN: Observational cohort. SETTING: Veterans Affairs inpatient medical centers (n=124). PARTICIPANTS: The derivation (2010-12; n=36,021) and validation (2013-15; n=30,364) cohorts included randomly selected veterans admitted for HF exacerbation (mean age 71±11; 98% male). MEASUREMENTS: The primary outcome was 30-day mortality. Secondary outcomes were 1- and 2-year mortality. Candidate variables were drawn from electronic medical records. Discriminatory function was measured as the area under the receiver operating characteristic curve. RESULTS: Thirteen risk factors were identified: age, ejection fraction, mean arterial pressure, pulse, brain natriuretic peptide, blood urea nitrogen, sodium, potassium, more than 7 inpatient days in the past year, metastatic disease, and prior palliative care. The model stratified participants into low- (1%), intermediate- (2%), high- (5%), and very high- (15%) mortality risk groups (C-statistic=0.72, 95% confidence interval (CI)=0.71-0.74). These findings were confirmed in the validation cohort (C-statistic=0.70, 95% CI=0.68-0.71). Subgroup analysis of age strata confirmed model discrimination. CONCLUSION: This simple prediction rule allows clinicians to risk-stratify individuals on admission for HF using characteristics captured in electronic medical record systems. The identification of high-risk groups allows individuals to be targeted for discussion of goals and treatment.

Body Mass Index Affects Proximal Femoral but Not Acetabular Morphology in Adolescents Without Hip Pathology.

BACKGROUND: Increased mechanical load secondary to a large body mass index (BMI) may influence bone remodeling. The purpose of this study was to investigate whether BMI is associated with the morphology of the proximal part of the femur and the acetabulum in a cohort of adolescents without a history of hip disorders. METHODS: We evaluated pelvic computed tomographic (CT) images in 128 adolescents with abdominal pain without a history of hip pathology. There were 44 male patients (34%) and the mean patient age (and standard deviation) was 15 ± 1.95 years. The alpha angle, head-neck offset, epiphysis tilt, epiphyseal angle, and epiphyseal extension were measured to assess femoral morphology. Measurements of acetabular morphology included lateral center-edge angle, acetabular Tönnis angle, and acetabular depth. BMI percentile, specific to age and sex according to Centers for Disease Control and Prevention growth charts, was recorded. RESULTS: BMI percentile was associated with all measurements of femoral morphology. Each 1-unit increase in BMI percentile was associated with a mean 0.15° increase in alpha angle (p < 0.001) and with a mean 0.03-mm decrease in femoral head-neck offset (p < 0.001). On average, a 1-unit increase in BMI percentile was associated with a 0.0006-unit decrease in epiphyseal extension (p = 0.03), a 0.10° increase in epiphyseal angle (p < 0.001), and a 0.06° decrease in tilt angle (p = 0.02; more posteriorly tilted epiphysis). There was no detected effect of BMI percentile on acetabular morphology including lateral center-edge angle (p = 0.33), Tönnis angle (p = 0.35), and acetabular depth (p = 0.88). CONCLUSIONS: Higher BMI percentile was associated with increased alpha angle, reduced head-neck offset and epiphyseal extension, and a more posteriorly tilted epiphysis with decreased tilt angle and increased epiphyseal angle. This morphology resembles a mild slipped capital femoral epiphysis deformity and may increase the shear stress across the growth plate, increasing the risk of slipped capital femoral epiphysis development in obese adolescents. BMI percentiles had no association with measurements of acetabular morphology. Further studies will help to clarify whether obese asymptomatic adolescents have higher prevalence of a subclinical slip deformity and whether this morphology increases the risk of slipped capital femoral epiphysis and femoroacetabular impingement development.

Acetabular Retroversion, but Not Increased Acetabular Depth or Coverage, in Slipped Capital Femoral Epiphysis: A Matched-Cohort Study.

BACKGROUND: Femoral head overcoverage by a deep and retroverted acetabulum has been postulated as a mechanical factor in slipped capital femoral epiphysis (SCFE). We assessed acetabular depth, coverage, and version in the hips of patients with unilateral SCFE; in the contralateral, uninvolved hips; and in healthy control hips. METHODS: Thirty-six patients affected by unilateral SCFE were matched to 36 controls on the basis of sex and age. The acetabular depth-width ratio (ADR), the lateral center-edge angle (LCEA), the anterior and posterior acetabular sector angle (ASA), and version (10 mm distal to the highest point of the acetabular dome and at the level of the femoral head center) were assessed on computed tomography (CT). A repeated-measures analysis of variance was used to assess differences among the SCFE, contralateral, and matched-control hips. Pairwise comparisons were conducted using Bonferroni correction for multiple comparisons. RESULTS: The mean coronal ADR was significantly lower in the hips affected by SCFE (311.6) compared with the contralateral hips (336.1) (p = 0.001) but did not differ from that of controls (331.9) (p = 0.08). The mean LCEA was significantly lower in the SCFE hips (29.8°) compared with the contralateral hips (33.7°) (p < 0.001) but did not differ from that of controls (32.2°) (p = 0.25). The mean anterior ASA did not differ between the SCFE hips (65.0°) and the contralateral hips (66.0°) (p = 0.68) or the control hips (64.5°) (p = 1.00). The mean posterior ASA in the SCFE hips (92.5°) was significantly lower than that in the contralateral hips (96.5°) (p = 0.002), but no difference was observed between the SCFE hips and controls (96.0°) (p = 0.83). The acetabulum was retroverted cranially in the SCFE hips compared with the contralateral hips (2.7° versus 6.6°; p = 0.01) and compared with controls (2.7° versus 9.6°; p = 0.005). A lower mean value for acetabular version at the level of the femoral head center was also observed in the SCFE hips compared with the contralateral hips (13.9° versus 15.5°; p = 0.04) and compared with controls (13.9° versus 16.0°; p = 0.045). No significant difference (p > 0.05) in acetabular measurements was observed between the contralateral and control hips. CONCLUSIONS: In SCFE, the acetabulum has reduced version but is not deeper, nor is there acetabular overcoverage. Additional longitudinal studies will clarify whether acetabular retroversion is a primary abnormality influencing the mechanics of SCFE development or an adaptive response to the slip. Our data suggest that the contralateral, uninvolved hip in patients with unilateral SCFE has normal acetabular morphology. LEVEL OF EVIDENCE: Prognostic Level III.

Predictors and trajectories of chronic postoperative pain following hip preservation surgery.

Factors contributing to chronic postoperative pain (CPOP) are poorly defined in young people and developmental considerations are poorly understood. With over 5 million children undergoing surgery yearly and 25% of adults referred to chronic pain clinics identifying surgery as the antecedent, there is a need to elucidate factors that contribute to CPOP in surgical patients. The present study includes patients undergoing hip preservation surgery at a children's hospital. The HOOS and SF-12 Health Survey were administered to 614 pre-surgical patients with 421 patients completing follow-up (6-months, 1-year and 2-years post-surgery). Pain, quality of life, and functioning across time were examined for each group within the population. A three trajectory model (low pain, pain improvement and high pain) emerged indicating three categories of treatment responders. Pain trajectory groups did not differ significantly on gender, pre-surgical age, BMI, prior hip surgery, surgical type, joint congruence or Tönnis grade. The groups differed significantly from each other on pre-surgical pain, pain chronicity, quality of life and functioning. Those in the high pain and pain improvement groups endorsed having pre-surgical depression at significantly higher rates and lower pre-surgical quality of life compared to those in the low pain group (P < 0.01). Those in the high pain group reported significantly worse pre-surgical functioning compared to those in the pain improvement (P < 0.0001) and low pain groups (P < 0.0001).The results demonstrate the need for preoperative screening prior to hip preservation surgery, as there may be a subset of patients who are predisposed to chronic pain independent of hip health.

Both 3-T dGEMRIC and Acetabular-Femoral T2 Difference May Detect Cartilage Damage at the Chondrolabral Junction.

BACKGROUND: In addition to case reports of gadolinium-related toxicities, there are increasing theoretical concerns about the use of gadolinium for MR imaging. As a result, there is increasing interest in noncontrast imaging techniques for biochemical cartilage assessment. Among them, T2 mapping holds promise because of its simplicity, but its biophysical interpretation has been controversial. QUESTIONS/PURPOSES: We sought to determine whether (1) 3-T delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) and T2 mapping are both capable of detecting cartilage damage at the chondrolabral junction in patients with femoroacetabular impingement (FAI); and (2) whether there is a correlation between these two techniques for acetabular and femoral head cartilage assessment. METHODS: Thirty-one patients with hip-related symptoms resulting from FAI underwent a preoperative 3-T MRI of their hip that included dGEMRIC and T2 mapping (symptomatic group, 16 women, 15 men; mean age, 27 ± 8 years). Ten volunteers with no symptoms according to the WOMAC served as a control (asymptomatic group, seven women, three men; mean age, 28 ± 3 years). After morphologic cartilage assessment, acetabular and femoral head cartilages were graded according to the modified Outerbridge grading criteria. In the midsagittal plane, single-observer analyses of precontrast T1 values (volunteers), the dGEMRIC index (T1Gd, patients), and T2 mapping values (everyone) were compared in acetabular and corresponding femoral head cartilage at the chondrolabral junction of each hip by region-of-interest analysis. RESULTS: In the symptomatic group, T1Gd and T2 values were lower in the acetabular cartilage compared with corresponding femoral head cartilage (T1Gd: 515 ± 165 ms versus 650 ± 191 ms, p < 0.001; T2: 39 ± 8 ms versus 46 ± 10 ms, p < 0.001). In contrast, the asymptomatic group demonstrated no differences in T1 and T2 values for the acetabular and femoral cartilages with the numbers available (T1: 861 ± 130 ms versus 860 ± 182 ms, p = 0.98; T2: 43 ± 7 ms versus 42 ± 6 ms, p = 0.73). No correlation with the numbers available was noted between the modified Outerbridge grade and T1, T1Gd, or T2 as well as between T2 and either T1 or T1Gd. CONCLUSIONS: Without the need for contrast media application, T2 mapping may be a viable alternative to dGEMRIC when assessing hip cartilage at the chondrolabral junction. However, acquisition-related phenomena as well as regional variations in the microstructure of hip cartilage necessitate an internal femoral head cartilage control when interpreting these results.

A phase Ib multiple ascending dose study of the safety, tolerability, and central nervous system availability of AZD0530 (saracatinib) in Alzheimer's disease.

INTRODUCTION: Despite significant progress, a disease-modifying therapy for Alzheimer's disease (AD) has not yet been developed. Recent findings implicate soluble oligomeric amyloid beta as the most relevant protein conformation in AD pathogenesis. We recently described a signaling cascade whereby oligomeric amyloid beta binds to cellular prion protein on the neuronal cell surface, activating intracellular Fyn kinase to mediate synaptotoxicity. Fyn kinase has been implicated in AD pathophysiology both in in vitro models and in human subjects, and is a promising new therapeutic target for AD. Herein, we present a Phase Ib trial of the repurposed investigational drug AZD0530, a Src family kinase inhibitor specific for Fyn and Src kinase, for the treatment of patients with mild-to-moderate AD. METHODS: The study was a 4-week Phase Ib multiple ascending dose, randomized, double-blind, placebo-controlled trial of AZD0530 in AD patients with Mini-Mental State Examination (MMSE) scores ranging from 16 to 26. A total of 24 subjects were recruited in three sequential groups, with each randomized to receive oral AZD0530 at doses of 50 mg, 100 mg, 125 mg, or placebo daily for 4 weeks. The drug:placebo ratio was 3:1. Primary endpoints were safety, tolerability, and cerebrospinal fluid (CSF) penetration of AZD0530. Secondary endpoints included changes in clinical efficacy measures (Alzheimer's Disease Assessment Scale - cognitive subscale, MMSE, Alzheimer's Disease Cooperative Study - Activities of Daily Living Inventory, Neuropsychiatric Inventory, and Clinical Dementia Rating Scale - Sum of Boxes) and regional cerebral glucose metabolism measured by fluorodeoxyglucose positron emission tomography. RESULTS: AZD0530 was generally safe and well tolerated across doses. One subject receiving 125 mg of AZD0530 was discontinued from the study due to the development of congestive heart failure and atypical pneumonia, which were considered possibly related to the study drug. Plasma/CSF ratio of AZD0530 was 0.4. The 100 mg and 125 mg doses achieved CSF drug levels corresponding to brain levels that rescued memory deficits in transgenic mouse models. One-month treatment with AZD0530 had no significant effect on clinical efficacy measures or regional cerebral glucose metabolism. CONCLUSIONS: AZD0530 is reasonably safe and well tolerated in patients with mild-to-moderate AD, achieving substantial central nervous system penetration with oral dosing at 100-125 mg. Targeting Fyn kinase may be a promising therapeutic approach in AD, and a larger Phase IIa clinical trial of AZD0530 for the treatment of patients with AD has recently launched. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01864655. Registered 12 June 2014.

Child outpatient mental health service use: why doesn't insurance matter?

BACKGROUND: Several recent studies of child outpatient mental health service use in the US have shown that having private insurance has no effect on the propensity to use services. Some studies also find that public coverage has no beneficial effect relative to no insurance. AIMS: This study explores several potential explanations, including inadequate measurement of mental health status, bandwagon effects, unobservable heterogeneity and public sector substitution for private services, for the lack of an effect of private insurance on service use. METHODS: We use secondary analysis of data from the three mainland US sites of NIMH's 1992 field trial of the Cooperative Agreement for Methodological Research for Multi-Site Surveys of Mental Disorders in Child and Adolescent Populations (MECA) Study. We examine whether or not a subject used any mental health service, school-based mental health services or outpatient mental health services, and the number of outpatient visits among users. We also examine use of general medical services as a check on our results. We conduct regression analysis; instrumental variables analysis, using instruments based on employment and parental history of mental health problems to identify insurance choice, and bivariate probit analysis to examine multiservice use. RESULTS: We find evidence that children with private health insurance have fewer observable (measured) mental health problems. They also appear to have a lower unobservable (latent) propensity to use mental health services than do children without coverage and those with Medicaid coverage. Unobserved differences in mental health status that relate to insurance choice are found to contribute to the absence of a positive effect for private insurance relative to no coverage in service use regressions. We find no evidence to suggest that differences in attitudes or differences in service availability in children's census tracts of residence explain the non-effect of insurance. Finally, we find that the lack of a difference is not a consequence of substitution of school-based for office-based services. School-based and office-based specialty mental health services are complements rather than substitutes. School-based services are used by the same children who use office-based services, even after controlling for mental health status. DISCUSSION: Our results are consistent with at least two explanations. First, limits on coverage under private insurance may discourage families who anticipate a need for child mental health services from purchasing such insurance. Second, publicly funded services may be readily available substitutes for private services, so that lack of insurance is not a barrier to adequate care. Despite the richness of data in the MECA dataset, cross-sectional data based on epidemiological surveys do not appear to be sufficient to fully understand the surprising result that insurance does not enable access to care. IMPLICATIONS FOR POLICY AND RESEARCH: Limits on coverage under private mental health insurance combined with a relatively extensive system of public mental health coverage have apparently generated a situation where there is no observed advantage to the marginal family of obtaining private mental health insurance coverage. Further research using longitudinal data is needed to better understand the nature of selection in the child mental health insurance market. Further research using better measures of the nature of treatment provided in different settings is needed to better understand how the private and public mental health systems operate.
