Modern Psychedelic Microdosing Research on Mental Health: A Systematic Review.

Objective: To investigate the relationship between psychedelic microdosing and its effects on mental health, aiming to understand if microdosing can improve mental well-being.Data Sources: PubMed and Scopus were searched on December 25, 2022, using search terms related to psychedelics, microdosing, and mental health. The inclusion criteria focused on studies published between January 1, 2012, and November 30, 2022. There were no language restrictions for the initial search; however, for the study selection, only articles in English were considered.Study Selection: A total of 45 articles were initially identified. After removing duplicates, 27 unique articles were screened based on their titles and abstracts, resulting in 19 articles included in the final review. The studies were selected based on their relevance to the relationship between mental health and psychedelic microdosing.Data Extraction: The extracted data from the selected studies included sample sizes, demographics, survey designs, and qualitative and quantitative analyses related to the outcomes of individuals with mental health issues who also engaged in psychedelic microdosing. The QualSyst Quality Assessment Checklist was used to assess the methodological rigor and quality of each study. The data extraction process involved systematically reviewing each article and summarizing key findings related to the impact of microdosing on mental health.Results: The review revealed that microdosing psychedelics, such as lysergic acid diethylamide and psilocybin, showed potential benefits on mental health. Users reported positive effects, including improved mood, increased focus, and better daily function. However, there were also challenges reported, such as physiologic discomfort and increased anxiety. Some studies observed that positive expectations about microdosing led to positive outcomes. The studies varied in design, with some being observational, others placebo-controlled, and some relying on self-reported data.Conclusions: There is a growing body of evidence suggesting a positive correlation between psychedelic microdosing and improved mental well-being. However, due to the limited number of controlled studies and the small sample sizes in some of the studies, the causal relationship between microdosing and mental health improvement remains uncertain. The review calls for further research with double-blind experiments, control groups, and larger sample sizes that represent the general population to better understand the potential benefits and risks of psychedelic microdosing on mental health.Prim Care Companion CNS Disord 2024;26(1):23r03581.Author affiliations are listed at the end of this article.

Improving Short Course Treatment of Pediatric Infections: A Randomized Quality Improvement Trial.

BACKGROUND AND OBJECTIVES: Short courses of antibiotic treatment are effective for pediatric community-acquired pneumonia (CAP) and skin and soft tissue infections (SSTI). We compared the effectiveness of education with performance feedback, clinical decision support (CDS), and the combination in encouraging appropriately short treatment courses by primary care clinicians. METHODS: We designed a site-randomized, quality improvement trial within a large pediatric primary care network. Each practice was randomly assigned to 1 of 4 groups: education and feedback; CDS; both interventions ("combined group"); and control. We performed difference-in-differences analysis to compare the proportion of cases with short course treatment before and after intervention among the 4 groups. RESULTS: For all cases of CAP and SSTI, the proportion in the control group treated with the recommended duration did not change from the baseline period (26.1% [679 of 2603]) to the intervention period (25.8% [196 of 761]; P = .9). For the education and feedback group, the proportion rose from 22.3% (428 of 1925) to 45.0% (239 of 532; P < .001); for the CDS group, from 26.6% (485 of 1824) to 52.3% (228 of 436; P < .001); and for the combined group, from 26.2% (491 of 1875) to 67.8% (314 of 463; P < .001). A difference-in-differences analysis showed that all 3 intervention groups improved performance compared with the control group (P < .001); the combined group had greater improvement than the education and feedback group or the CDS group (P < .001). CONCLUSIONS: In this quality improvement project to encourage shorter duration treatment of CAP and SSTI, both education with performance feedback and CDS were effective in modifying clinician behavior; however, the combination of the two was substantially more effective than either strategy alone.

Trends in Telehealth Antibiotic Prescribing for Children Through the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVES: Telehealth visits increased significantly during the coronavirus disease 2019 pandemic without consensus on the appropriate scope of telehealth antibiotic prescribing within pediatric primary care. We describe telehealth antibiotic prescribing patterns within our statewide pediatric primary care network during the coronavirus disease 2019 pandemic. METHODS: In a retrospective observational study of a large statewide pediatric primary care network, we identified and analyzed telehealth and in-person encounters with oral antibiotics prescribed from March 2020 to July 2021. We focused on the top 5 general diagnosis groupings using International Classification of Disease 10 codes. RESULTS: Of the 55 926 encounters with an oral antibiotic prescribed, 12.5% were conducted via telehealth and 87.5% in person. The proportion of telehealth antibiotic encounters varied significantly according to diagnosis category (P <.001): ear (30.8%), skin and subcutaneous (21.8%), respiratory (18.8%), genitourinary (6.3%), and Lyme disease infections (3.8%). The proportion of telehealth antibiotic encounters for all diagnosis categories peaked in spring of 2020. The greatest proportion of telehealth antibiotic prescribing during the most recent 4weeks of the analysis were Lyme disease infections (11.7%) and for skin and subcutaneous tissue infections (3.1%). CONCLUSIONS: Telehealth continues to be used to prescribe antibiotics even after the initial stage of the pandemic. Clinicians and patients would benefit from clearer guidelines about the appropriate use of antibiotics prescribed during telehealth encounters.

Patient-delivered partner therapy: One option for management of sexual partner(s) of a patient diagnosed with a chlamydia infection.

BACKGROUND: Chlamydia is the most commonly diagnosed bacterial sexually transmissible infection (STI) in Australia. Partner management is key to reducing transmission and a cornerstone of best practice chlamydia management. While most patients will opt for telling their partner(s) themselves, patient-delivered partner therapy (PDPT) offers an alternative way to inform and treat partners where usual management is inappropriate or unlikely to be undertaken. Guidelines for PDPT vary across Australia. Recent research found that general practitioners (GP)s want practical guidance for using PDPT in appropriate situations. OBJECTIVE: The aim of this article is to provide an overview of the process of offering PDPT and note the challenges GPs may face in its provision. DISCUSSION: PDPT is one option for partner management when sexual partner(s) are unlikely or unable to seek timely care themselves. However, there are challenges to the use of PDPT in general practice. The provision of clear guidelines is an essential step to promote its appropriate use.

Patient delivered partner therapy for chlamydia infection is used by some general practitioners, but more support is needed to increase uptake: findings from a mixed-methods study.

OBJECTIVES: Patient-delivered partner therapy (PDPT) describes the giving of a prescription or antibiotics by an index case with chlamydia to their sexual partners. PDPT has been associated with higher numbers of partners receiving treatment. In Australia, general practitioners (GPs) previously expressed negative views about PDPT. Health authority guidance for PDPT has since been provided in some areas. We investigated recent use and perceptions of PDPT for chlamydia among GPs in Australia. METHODS: In 2019, we conducted an online survey comprising multiple-choice and open-ended questions to investigate GPs' chlamydia management practices, including PDPT. Logistic regression identified factors associated with ever offering PDPT. A directed content analysis of free-text data explored GPs' perceptions towards PDPT. RESULTS: The survey received responses from 323 GPs; 85.8% (n=277) answered PDPT-focused questions, providing 628 free-text comments. Over half (53.4%) reported never offering PDPT, while 36.5% sometimes and 10.1% often offered PDPT. GPs more likely to offer PDPT were aged ≥55 years (adjusted OR (AOR) 2.9, 95% CI 1.4 to 5.8), worked in non-metropolitan areas (AOR 2.5, 95% CI 1.5 to 4.4) and jurisdictions with health authority PDPT guidance (AOR 2.3, 95% CI 1.4 to 3.9). Qualitative data demonstrated that many GPs recognised PDPT's potential to treat harder to engage partners but expressed hesitancy to offer PDPT because they considered partners attending for care as best practice. GPs emphasised a case-by-case approach that considered patient and partner circumstances to determine PDPT suitability. To alleviate medicolegal concerns, many GPs indicated a need for professional and health authority guidance that PDPT is permissible. They also desired practical resources to support its use. CONCLUSION: GPs appear to accept the place of PDPT as targeted to those who may otherwise not access testing or treatment. Availability of health authority guidance appears to have supported some GPs to incorporate PDPT into their practice.

Patient-delivered partner therapy for chlamydia in Australia: can it become part of routine care?

Background Patient-delivered partner therapy (PDPT) is a method for an index patient to give treatment for genital chlamydia to their sexual partner(s) directly. In Australia, PDPT is considered suitable for heterosexual partners of men and women, but is not uniformly endorsed. We explored the policy environment for PDPT in Australia and considered how PDPT might become a routine option. METHODS: Structured interviews were conducted with 10 key informants (KIs) representing six of eight Australian jurisdictions and documents relevant to PDPT were appraised. Interview transcripts and documents were analysed together, drawing on KIs' understanding of their jurisdiction to explore our research topics, namely the current context for PDPT, challenges, and actions needed for PDPT to become routine. RESULTS: PDPT was allowable in three jurisdictions (Victoria, New South Wales, Northern Territory) where State governments have formally supported PDPT. In three jurisdictions (Western Australia, Australian Capital Territory, Tasmania), KIs viewed PDPT as potentially allowable under relevant prescribing regulations; however, no guidance was available. Concern about antimicrobial stewardship precluded PDPT inclusion in the South Australian strategy. For Queensland, KIs viewed PDPT as not allowable under current prescribing regulations and, although a Medicine and Poisons Act was passed in 2019, it is unclear if PDPT will be possible under new regulations. Clarifying the doctor-partner treating relationship and clinical guidance within a care standard were viewed as crucial for PDPT uptake, irrespective of regulatory contexts. CONCLUSION: Endorsement and guidance are essential so doctors can confidently and routinely offer PDPT in respect to professional standards and regulatory requirements.

Electronic Documentation in Pediatrics: The Rationale and Functionality Requirements.

Clinical documentation has dramatically changed since the implementation and use of electronic health records and electronic provider documentation. The purpose of this report is to review these changes and promote the development of standards and best practices for electronic documentation for pediatric patients. In this report, we evaluate the unique aspects of clinical documentation for pediatric care, including specialized information needs and stakeholders specific to the care of children. Additionally, we explore new models of documentation, such as shared documentation, in which patients may be both authors and consumers, and among care teams while still maintaining the ability to clearly define care and services provided to patients in a given day or encounter. Finally, we describe alternative documentation techniques and newer technologies that could improve provider efficiency and the reuse of clinical data.

Electronic Documentation in Pediatrics: The Rationale and Functionality Requirements.

Clinical documentation is a fundamental component of the practice of medicine. It has significantly evolved over the past decade, largely because of the growth of health information technology and electronic health records. Although government agencies and other professional organizations have published position statements on the structure and use of electronic documentation, few have specifically addressed the documentation needs for the care of children. A policy statement on electronic documentation of clinical care by general pediatric and subspecialist providers by the American Academy of Pediatrics is needed. This statement provides insight on the unmet needs of key stakeholders to direct future research and development of the electronic media necessary to enhance the wellness of children and improve health care delivery. It also addresses the challenges and opportunities for efficient and effective clinical documentation in pediatrics.

Risk factors associated with severity of dry eye syndrome in ocular graft-versus-host disease.

OBJECTIVE: The aim of this study was to identify risk factors for the development of severe dry eye syndrome (DES) in patients with ocular graft-versus-host disease (oGVHD). DESIGN: Retrospective Chart Review. PARTICIPANTS: Patients undergoing allogeneic hematopoietic stem cell transplantation at the British Columbia Cancer Agency between 2011 and 2013. METHODS: A retrospective chart review of post-transplant patients with oGVHD DES followed at the British Columbia Cancer Agency Bone Marrow Transplant Unit was performed. Patient and donor data were collected. Descriptive and inferential statistics were carried out. Linear, logistic, and ordered logistic regression analyses were carried out. DES severity was graded using the National Institutes of Health criteria. RESULTS: Of the 78 patients studied, 39 (50%) were male. The median age and Schirmer score were 56 years (range 24-71 years) and 14 mm (range 0-25 mm), respectively. A lower Schirmer score (p = 0.0001), severe overall chronic graft-versus-host disease (GVHD) (p < 0.0001), and lung involvement (p = 0.04) were associated with worsening oGVHD DES. Ordered logistic regression analysis revealed characteristics predictive of oGVHD severity. Fourteen patients (17.95%) had severe DES. Compared with those with nonsevere DES, this group was more likely to be male (p = 0.02) and have a lower Schirmer score (p = 0.01), significantly worse overall chronic GVHD (p = 0.002), as well as lung (p = 0.02) and gastrointestinal tract (p = 0.02) involvement. Logistic regression analysis revealed characteristics predictive of severe oGVHD DES. CONCLUSION: This study identified potential risk factors associated with the development of severe DES in patients with oGVHD.

Effect of an Electronic Health Record Transition on the Provision of Recommended Well Child Services in Pediatric Primary Care Practices.

We sought to determine the effect of transitioning between electronic health record (EHR) systems on the quality of preventive care in a large pediatric primary care network. To study this, we performed a retrospective chart analysis of 42 primary care practices from the Pediatric Physicians' Organization at Children's who transitioned EHRs. We reviewed 24 random encounters per week distributed evenly across 6 age categories before, during, and after a transition period. We reviewed encounter documentation for age-appropriate well child services, per American Academy of Pediatrics/Bright Futures guidelines. Logistic regression and statistical process control analysis were used. In the pretransition period, 84.5% of all recommended elements were documented versus 86.4% posttransition (P = .04). Documentation of age-appropriate anticipatory guidance showed significant positive change (69.0% to 80.2%, P = .005), but it was the only subdomain with a statistically significant increase. These increases suggest that EHR transitions have the opportunity to affect the delivery of preventive care.

Increasing Recognition and Diagnosis of Adolescent Depression: Project RedDE: A Cluster Randomized Trial.

Adolescent depression causes appreciable morbidity and is underdiagnosed in primary care. This study investigated whether a quality improvement collaborative (QIC) increases the frequency of adolescent depression diagnoses, thus reducing missed diagnoses. METHODS: During a cluster-randomized clinical trial, a national cohort of primary care pediatric practices worked in different orders based on randomization to improve performance on each of three different diagnoses; one was increasing adolescent depression diagnoses. While improving their first diagnosis during an 8-month action period, practices collected control data for a different diagnosis. In two subsequent 8-month periods, practices worked to improve two additional diagnoses and continued to provide data on the ability to sustain and maintain improvements. The QIC intervention included day-long video conferences, transparent data sharing, analysis of failures, QI coaching, and tools to help improve diagnostic performance, including the Patient Health Questionnaire-9 Modified. The primary outcome was the measured frequency of depression diagnoses in adolescent health supervision visits compared via generalized mixed-effects regression models. RESULTS: Forty-three practices were randomized with 31 in the final analysis. We included 3,394 patient visits in the control and 4,114 in the intervention phases. The adjusted percentage of patients with depression diagnoses increased from 6.6% in the control to 10.5% in intervention phase (Risk Difference (RD) 3.9%; 95% CI 2.4%, 5.3%). Practices sustained these increases while working on different diagnoses during the second (RD -0.4%; 95% CI -2.3, 1.4%), and third action periods (RD -0.1%; 95% CI -2.7%, 2.4%). CONCLUSIONS: A QIC intervention can sustainably increase adolescent depression diagnoses.

The design and conduct of Project RedDE: A cluster-randomized trial to reduce diagnostic errors in pediatric primary care.

BACKGROUND: Diagnostic errors contribute to the large burden of healthcare-associated harm experienced by children. Primary care settings involve high diagnostic uncertainty and limited time and information, creating ideal conditions for diagnostic errors. We report on the design and conduct of Project RedDE, a stepped-wedge, cluster-randomized controlled trial of a virtual quality improvement collaborative aimed at reducing diagnostic errors in pediatric primary care. METHODS: Project RedDE cluster-randomized pediatric primary care practices into one of three groups. Each group participated in a quality improvement collaborative targeting the same three diagnostic errors (missed diagnoses of elevated blood pressure and adolescent depression and delayed diagnoses of abnormal laboratory studies), but in a different sequence. During the quality improvement collaborative, practices worked both independently and collaboratively, leveraging general quality improvement strategies (e.g. process mapping) in addition to error-specific content (e.g. pocket guides for blood pressure norms) delivered during the intervention phase for each error. The quality improvement collaborative intervention included interactive learning sessions and webinars, quality improvement coaching at the team level, and repeated evaluation of failures via root cause analyses. Pragmatic data were collected monthly, submitted to a centralized data aggregator, and returned to the practices in the form of run charts comparing each practice's progress over time to that of the group. The primary analysis used patients as the unit of analysis and compared diagnostic error proportions between the intervention and baseline periods, while secondary analyses evaluated the sustainability of observed reductions in diagnostic errors after the intervention period ended. RESULTS: A total of 43 practices were recruited and randomized into Project RedDE. Eleven practices withdrew before submitting any data, and one practice merged with another participating practice, leaving 31 practices that began work on Project RedDE. All but one of the diverse, national pediatric primary care practices that participated ultimately submitted complete data. Quality improvement collaborative participation was robust, with an average of 63% of practices present on quality improvement collaborative webinars and 85% of practices present for quality improvement collaborative learning sessions. Complete data included 30 months of outcome data for the first diagnostic error worked on, 24 months of outcome data for the second, and 16 months of data for the third. LESSONS LEARNED AND LIMITATIONS: Contamination across study groups was a recurring concern; concerted efforts were made to mitigate this risk. Electronic health records played a large role in teams' success. CONCLUSION: Project RedDE, a virtual quality improvement collaborative aimed at reducing diagnostic errors in pediatric primary care, successfully recruited and retained a diverse, national group of pediatric primary care practices. The stepped-wedge, cluster-randomized controlled trial design allowed for enhanced scientific efficiency.

Diagnostic Errors in Primary Care Pediatrics: Project RedDE.

OBJECTIVE: Diagnostic errors (DEs), which encompass failures of accuracy, timeliness, or patient communication, cause appreciable morbidity but are understudied in pediatrics. Pediatricians have expressed interest in reducing high-frequency/subacute DEs, but their epidemiology remains unknown. The objective of this study was to investigate the frequency of two high-frequency/subacute DEs and one missed opportunity for diagnosis (MOD) in primary care pediatrics. METHODS: As part of a national quality improvement collaborative, 25 primary care pediatric practices were randomized to collect 5 months of retrospective data on one DE or MOD: elevated blood pressure (BP) and abnormal laboratory values (DEs), or adolescent depression evaluation (MOD). Relationships between DE or MOD proportions and patient age, gender, and insurance status were explored with mixed-effects logistic regression models. RESULTS: DE or MOD rates in pediatric primary care were found to be 54% for patients with elevated BP (n = 389), 11% for patients with abnormal laboratory values (n = 381), and 62% for adolescents with an opportunity to evaluate for depression (n = 400). When examining the number of times a pediatrician may have recognized an abnormal condition but either knowingly or unknowingly did not act according to recommended guidelines, providers did not document recognition of an elevated BP in 51% of patients with elevated BP, and they did not document recognition of an abnormal laboratory value without a delay in 9% of patients with abnormal laboratory values. CONCLUSIONS: DEs and MODs occur at an appreciable frequency in pediatric primary care. These errors may contribute to care delays and patient harm.

Primary care pediatricians' interest in diagnostic error reduction.

BACKGROUND: Diagnostic errors causing harm in children are understudied, resulting in a knowledge gap regarding pediatricians' interest in reducing their incidence. METHODS: Electronic survey of general pediatricians focusing on diagnostic error incidence, errors they were interested in trying to improve, and errors reduced by their electronic health record (EHR). RESULTS: Of 300 contacted pediatricians, 77 (26%) responded, 58 (19%) served ambulatory patients, and 48 (16%) completed the entire questionnaire. Of these 48, 17 (35%) reported making a diagnostic error at least monthly, and 16 (33%) reported making a diagnostic error resulting in an adverse event at least annually. Pediatricians were "most" interested in "trying to improve" missed diagnosis of hypertension (17%), delayed diagnosis due to missed subspecialty referral (15%), and errors associated with delayed follow-up of abnormal laboratory values (13%). Among the 44 pediatricians with an EHR, 16 (36%) said it reduced the likelihood of missing obesity and 14 (32%) said it reduced the likelihood of missing hypertension. Also, 15 (34%) said it helped avoid delays in follow-up of abnormal laboratory values. A third (36%) reported no help in diagnostic error reduction from their EHR. CONCLUSIONS: Pediatricians self-report an appreciable number of diagnostic errors and were most interested in preventing high frequency, non-life-threatening errors. There exists a need to leverage EHRs to support error reduction efforts.

Risk factors for the development of ocular graft-versus-host disease (GVHD) dry eye syndrome in patients with chronic GVHD.

BACKGROUND: To investigate the factors associated with the development of ocular graft-versus-host disease (oGVHD) dry eye syndrome (DES) in patients with chronic GVHD (cGVHD) after receiving allogenic haematopoietic stem cell transplantation (AHSCT) METHODS: A retrospective chart review of patients receiving AHSCT between 1998 and 2013 at the Bone Marrow Transplant Unit of the British Columbia Cancer Agency was carried out. Demographic and clinical data from both donors and recipients were obtained. The diagnostic criteria for the development of oGVHD DES from the National Institutes of Health were used to identify patients with the disease. Descriptive and inferential statistics were carried out. RESULTS: A total of 146 patients with a median follow-up time of 24.0 months (range 11.3-249.7 months) were included in this study. Sixty-six (45.2%) patients were women. Seventy-seven (52.7%) patients had oGVHD DES. The median age of patients was 57 years (range 25-71 years). Compared with other ethnicities, Caucasian patients were less likely to develop oGVHD DES, with an OR of 0.29 (p=0.01). Patients who received a transplant from Epstein-Barr-positive donors had a higher prevalence of oGVHD DES (OR=4.39, p=0.01). This was also found in patients with the following systemic involvement of cGVHD: grade 1-3 cGVHD skin involvement (OR=1.57, p=0.01), oral involvement (OR=2.51, p=0.01) and liver involvement (p=0.04). Patients with grade 2-3 overall cGVHD were also more susceptible to oGVHD DES (OR=2.72, p<0.001). CONCLUSIONS: This study identified risk factors associated with a higher prevalence of oGVHD DES in post-AHSCT patients with cGVHD.

Impact of newborn follow-up visit timing on subsequent ED visits and hospital readmissions: an instrumental variable analysis.

OBJECTIVE: To determine whether newborn first outpatient visit (FOV) within 3 days of discharge is associated with reduced rates of emergency department (ED) visits and hospital readmissions. METHODS: Retrospective cohort analysis was performed of all newborns who were born and had outpatient follow-up within a large academic medical center to determine whether they had ED visits or hospital readmission within 2 weeks after hospital discharge. Multivariable regression using an instrumental variable for timing of FOV was conducted to estimate the relationship between FOV within 3 days of discharge and ED visits and hospital readmissions within 2 weeks of discharge, adjusting for potential confounders. Stratified analyses assessed this relationship in subpopulations with medical or social risk factors. RESULTS: Of 3282 newborns, 178 (5%) had 1 or more ED visits or hospital readmissions within 2 weeks of hospital discharge. FOV within 3 days was not significantly associated with ED visits and readmissions in the instrumental variable analysis (IVA) (-0.035, P = .11) or the ordinary least squares analysis (OLS) (0.006, P = .52). The difference in coefficients between these analyses, however, suggests that IVA successfully adjusted for some unmeasured bias. In stratified analyses, only newborns born to African American mothers or discharged by family medicine providers demonstrated a significant relationship between FOV within 3 days and reduced odds of ED visits and readmissions. CONCLUSIONS: No significant relationship between outpatient visit timing and ED visits and hospital readmissions was found. Further study is needed to assess the impact of early outpatient visits on other newborn outcomes.

Factors associated with timing of first outpatient visit after newborn hospital discharge.

OBJECTIVE: To determine factors associated with newborns having their first outpatient visit (FOV) beyond 3 days after postpartum hospital discharge. METHODS: Retrospective cohort analysis of all newborns born at a large urban university hospital during a 1-year period, discharged home within 96 hours of birth, and with an outpatient visit with an affiliated provider within 60 days after discharge. RESULTS: Of 3282 newborns, 1440 (44%) had their FOV beyond 3 days after discharge. Newborns born to first-time mothers, breast-feeding, at high risk for hyperbilirubinemia, or with a pathological diagnosis were significantly (P < .05) less likely to have FOV beyond 3 days in adjusted multivariable analysis, while newborns born via Caesarian section, of older gestational age, with Medicaid insurance, or discharged on a Thursday or Friday were more likely to have FOV beyond 3 days. Discharging provider characteristics independently associated with FOV beyond 3 days included family medicine providers, providers out of residency longer, and providers practicing at the institution longer. In addition, practice of outpatient follow-up had an independent impact on timing of FOV. Having an appointment date and time recorded on the nursery record or first appointment with a home nurse decreased the odds that time to FOV was beyond 3 days of discharge. CONCLUSIONS: Physician decisions regarding timing of outpatient visit after newborn discharge may take into account newborn medical and social characteristics, but certain patient, provider, and practice features associated with this timing may represent unrecognized barriers to care.
