Trade-offs in locational choices for care coordination resources in accountable care organizations.

BACKGROUND: Care coordination is central to accountable care organizations (ACOs), especially in Medicaid where many patients have complex medical and social needs. Little is known about how to best organize care coordination resources in this context, particularly whether to centralize them. We examined how care coordinators' location, management, and colocation of both (within ACO headquarters, practice sites, or other organizations) relate to care quality and coordination. METHODS: We conducted a cross-sectional analysis of surveys administered to a sample of practice sites covering all 17 Medicaid ACOs in Massachusetts ( n = 225, response rate = 64%). We applied controlled, cluster-robust regressions, adjusting the significance threshold for the number of ACO clusters, to assess how clinical information sharing across settings, care quality improvement, knowledge of social service referral, and cross-resource coordination (i.e., the ability of multiple resources to work well together) relate to where care coordinators were physically located and/or managed. RESULTS: Centralizing care coordinators at ACO headquarters was associated with greater information sharing. Embedding care coordinators in practices was associated with greater care quality improvement. Embedding coordinators at other organizations was associated with less information sharing and care quality improvement. Managing coordinators at practice sites and other organizations were associated with better care quality improvement and cross-resource coordination, respectively. Colocating the two functions showed no significant differences. PRACTICE IMPLICATIONS: Choosing care coordinators' locations may present trade-offs. ACOs may strategically choose embedding care coordinators at practice sites for enhanced care quality versus centralizing them at the ACO to facilitate information sharing.

Understanding Impacts of Online Dual Practice on Health System Performance: A Qualitative Study in China.

The outbreak of the COVID-19 pandemic has boosted the global development of online healthcare platforms. An increasing number of public hospital doctors are providing online services on private third-party healthcare platforms, creating a new form of dual practice-online dual practice. To explore the impacts of online dual practice on health system performance as well as potential policy responses, we undertook a qualitative approach that uses in-depth interviews and thematic analysis. Following a purposive sampling, we interviewed 57 Chinese respondents involved in online dual practice. We asked respondents for their opinions on the effects of online dual practice on access, efficiency, quality of care, and advice on regulatory policy. The results suggest that online dual practice can generate mixed impacts on health system performance. The benefits include improved accessibility due to increased labor supply of public hospital doctors, better remote access to high-quality services, and lower privacy concerns. It can improve efficiency and quality by optimizing patient flows, reducing repetitive tasks, and improving the continuity of care. However, the potential distraction from designated work at public hospitals, inappropriate use of virtual care, and opportunistic physician behaviors may undermine overall accessibility, efficiency, and quality. Countries should mitigate these adverse consequences via regulations that are appropriate to their healthcare system context, policy priority, and governance capacity.

Mitigating donor interests in the case of COVID-19 vaccine: the implication of COVAX and DAC membership.

INTRODUCTION: The COVID-19 vaccine donation process allegedly prioritised national interests over humanitarian needs. We thus examined how donors allocated vaccines by recipient country needs versus donor national interests and how such decisions varied across donation channels (bilateral vs COVAX with country earmarking) or exposure to foreign aid norms (membership status in the Development Assistance Committee-DAC). METHODS: We used the two-part regression model to examine how the probability of becoming a recipient country and the volume of vaccines received were associated with recipient countries' needs (disease burden and GDP per capita), donor countries' interests (bilateral trade volume and voting distance in the United Nations General Assembly) and recipient countries' population size. The analysis further interacted the determinants with channel and DAC status. RESULTS: Donors preferentially selected countries with higher disease burden, lower GDP per capita, closer trade relations, more different voting preferences, and smaller populations. Compared with bilateral arrangements, COVAX encouraged more needs-based considerations (lower GDP per capita), less interest-based calculus (more distant economic relations and voting preferences) and larger population size. Compared with the DAC counterparts, the non-DAC donors focused more on politically and economically aligned countries but also on less economically developed countries. As for the volume of vaccines donated, countries received more vaccines if they had tighter trade relations with donors, more different voting patterns than donors, and larger populations. COVAX was associated with raising the volumes of vaccines to politically distant countries, and non-DAC donors donated more to countries with stronger trade relations and political alignment. CONCLUSION: Donors consider both recipient needs and national interests when allocating COVID-19 vaccines. COVAX and DAC partially mitigated donors' focus on domestic interests. Future global health aid can similarly draw on multilateral and normative arrangements.

How previous epidemics enable timelier COVID-19 responses: an empirical study using organisational memory theory.

INTRODUCTION: There has been little systematic exploration into what affects timeliness of epidemic response, despite the potential for earlier responses to be more effective. Speculations have circulated that previous exposure to major epidemics helped health systems respond more quickly to COVID-19. This study leverages organisational memory theory to test whether health systems with any, more severe, or more recent exposure to major epidemics enacted timelier COVID-19 policy responses. METHODS: A data set was constructed cataloguing 846 policies across 178 health systems in total, 37 of which had major epidemics within the last 20 years. Hypothesis testing used OLS regressions with World Health Organization region fixed effects, controlling for several health system expenditure and political variables. RESULTS: Results show that exposure to any major epidemics was associated with providing earlier response in the following policy categories: all policies, surveillance/response, distancing, and international travel policies. The effect was about 6-10 days earlier response. The significance of this variable was largely nullified with the addition of the other two independent variables. Neither total cases nor years since previous epidemics showed no statistical significance. CONCLUSION: This study suggests that health systems may learn from past major epidemics. Policymakers ought to institutionalise lessons from COVID-19. Future studies can examine specific generalisable lessons and whether timelier responses correlated with lower health and economic impacts.

Exploring the Construct of Psychological Safety in Medical Education.

PURPOSE: Psychological safety (PS) is recognized as key in health professions education. However, most studies exploring PS in medical education have focused on mistreatment, thus focusing on what PS is not. The authors set out to explicitly explore learners' concept of PS in the context of medical education to better understand and define PS and its educational consequences for medical students. METHOD: This descriptive exploratory study was conducted in the context of a pilot peer-assisted learning (PAL) program. The program brought together residents and medical students for 16 semiformal learning sessions. Eight medical students from a PAL program were recruited for semistructured interviews to explore their experiences of PS. Transcripts were thematically analyzed using an inductive approach, and social ecological theory was integrated in the later stages of analysis. RESULTS: Students described PS as not feeling judged. Having supportive relationships with peers and mentors improved PS. Students' sense of PS appeared to free them to focus on learning in the present moment without considering the consequences for their image in the eyes of others. Feeling safe also seemed to facilitate relationship building with the mentors. CONCLUSIONS: A sense of PS appears to free learners from constantly being self-conscious about projecting an image of competence. This enables learners to be present in the moment and concentrate on engaging with the learning task at hand. The authors propose that the term "educational safety" be used to describe a relational construct that can capture the essence of what constitutes PS for learners.

Decreasing HIV, Syphilis, and Hepatitis C Infection After a Decade of Harm Reduction Implementation Among Drug Users in Southwestern Areas of China.

OBJECTIVE: Since 2003, the Chinese central government has implemented several harm reduction and preventive measures to control HIV. We aim to describe epidemiological trends of HIV, hepatitis C virus (HCV), and syphilis in Guangxi drug users after the policy implementation. METHOD: A total of 12,161-15,870 drug users in Guangxi, China, were recruited annually from 2009 to 2015 through community outreach or snowball sampling. The participants' demographics, behavior, and infection status were used to characterize rates of protective behaviors and disease prevalence (HIV, syphilis, and HCV). Chi-squared trend testing was used. RESULTS: Relative to baseline, the prevalence of HIV, HCV, and syphilis decreased from 13.6% to 6.2%, 68.0% to 50.5%, and 8.5% to 5.2%, respectively, by 2015. Concurrently, the rate of injecting drugs, needle sharing, unprotected last sexual encounter, and regular unprotected intercourse decreased from 82.6% to 64.5%, 24.1% to 5.5%, 66.6% to 39.7%, and 74.0% to 51.2%, respectively. The usage of prevention services, methadone maintenance therapy or needle exchange, peer education programs, HIV testing in the previous year, and knowledge of HIV status increased from 63.4% to 93.6%, 52.0% to 56.6%, 37.4% to 43.1%, 45.3% to 91.3%, and 76.7% to 99.4%, respectively, from 2009 to 2015. CONCLUSIONS: After a decade of HIV control policies, this was the first Chinese study to show a decreasing prevalence of HIV, HCV, and syphilis in the context of increasing uptake of protective services and behaviors.

FACTORS INFLUENCING LAY AND PROFESSIONAL HEALTH WORKERS' SELF-EFFICACY IN IDENTIFICATION AND INTERVENTION FOR ALCOHOL, TOBACCO, AND OTHER SUBSTANCE USE DISORDERS IN KENYA.

The global burden of substance use disorders (SUDs), including alcohol and tobacco, disproportionately affect low- and middle-income countries (LMICs), considering their rising disease burden and low service capacity. Nested within a Kenyan training program, this study explores factors associated with healthcare providers' self-efficacy to treat SUD. Surveys of 206 healthcare workers were used to perform regression and sensitivity analysis assessing various factors association with self-efficacy. Self-efficacy for SUD was lower in those practicing in public facilities and perceiving a need for alcohol use disorder (AUD) training; while higher self-efficacy correlated with a higher proportion of patients with AUD in one's setting, access to mental health worker support, cannabis use at a moderate risk level, and belief that AUD is manageable in outpatient settings. Increasing awareness about SUD prevalence, identification, and treatment skills could improve the self-efficacy of LMICs' health care providers and therefore the willingness to implement more services for patients with SUDs.

Identification of two novel BCKDHA mutations in a Chinese patient with maple syrup urine disease.

Maple syrup urine disease (MSUD) is an autosomal recessive metabolic disorder affecting branched-chain amino acids. Mutations in the BCKDHA, BCKDHB, and DBT gene impair the branched-chain alpha-ketoacid dehydrogenase (BCKD) complex, resulting in the accumulation of branched-chain amino acids and branched-chain alpha-ketoacid in tissues and plasma. This leads to mental and physical retardation, feeding problems, and a maple syrup odor in the urine. In this study, we describe the clinical and biochemical manifestations of a sporadic mutation in a neonate with classic MSUD. Analysis of the BCKDHA gene revealed a compound heterozygous mutation consisting of two novel missense mutations (p.L103P and p.R265P). Viewing the protein with PyMOL indicated that the p.L103P and p.R265P mutations were, respectively, located in the helical region and core domains of the BCKD's Ela component. The p.L103P mutation affected the hydrophobic cores and is predicted to shorten the helix; the p.R265P mutation can predictably affect the cofactor binding site by ligating the associated manganese ion. In conclusion, we identified two novel missense mutations in the BCKDHA gene in a Chinese patient with MSUD.

Molecular characterization of 25 Chinese pedigrees with 21-hydroxylase deficiency.

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders mainly caused by a defect in the steroid 21-hydroxylase gene (CYP21A2). In this study, we investigated the molecular defects of 25 Chinese pedigrees with 21-hydroxylase deficiency (21-OHD). Diagnosis of the probands in the families was based on their typical clinical presentations, such as inborn ambiguous genitalia, or early onset of salt wasting and biochemical metabolite abnormalities. All 10 exons and exon-intron boundaries of the CYP21A2 gene were amplified from the genomic DNA of the probands and then analyzed by direct sequencing. The phenotypes of the 26 patients from 25 pedigrees were classified as the classical form of 21-OHD. One novel mutation (c.1223 G>T) and 13 recurrent mutations of CYP21A2 were identified in the 25 pedigrees by genetic analysis. The novel c.1223 G>T mutation results in the substitution of arginine by leucine at amino acid position 408 (p.Arg408Leu). The most frequent mutation alleles were IVS2-13A/C>G (14/52) and I172N (11/52), followed by chimeric mutations (10/52). Forty six of 52 mutated alleles resulted from pseudogene conversion and 6 of 52 from random mutations. The spectrum of CYP21A2 mutation in our study was slightly different from those previously reported in Chinese and in other ethnic groups of the world. Although microconversion events were the main cause of mutations in the CYP21 gene, random mutations with a common origin can also be the reason for 21-OHD.
