Experiences in global mental health.

Participating in Global Mental Health program development and education and training efforts is rewarding and exciting work. The author describes several global experiences he has engaged in over the past 30 years, which has focused on teaching and encouraging family therapy and mental health care that support human rights and promote human development as innovated and promoted by the Global Alliance for Behavioral Health, formerly the American Orthopsychiatric Association. The author learned through participation that merely presenting mental health information and treatment approaches through lecture presentation was not adequate to help professionals and advocates in low- and middle-income countries to build sustainable mental health care systems in their home regions. The author engaged in several collaborative program development efforts with local professionals at their invitation. These programs, consisting of multiyear partnerships based on the needs and culture of the home region, will be described in the article. The programs, based on relationships between local professionals and a U.S. team of experts in child mental health care, had long-term positive effects and were highly rewarding. The basis for these programs was an invitation by local professionals, followed by collaboration in setting the agenda for the U.S. professionals' visits, an on-going relationship in which local professionals trusted that the visitors want and need to understand the local cultural environment, and improvements that will be most helpful and sustainable. In this process, the author learned about the cultures he worked in and was a part of extremely meaningful and enlightening relationships and experiences.

Dialog Across Cultures: Therapy for Diverse Families.

Child and adolescent psychiatrists (CAPs) work at the intersections of families, cultures, and systems, which affect engagement in care, assessment, and treatment planning. There are several practical strategies that CAPs can apply to practice cultural humility, to join with families, to facilitate difficult conversations and to work through misalignment. Culturally inclusive family-based care can promote greater understanding and lead to stronger outcomes with families as well as help mitigate mental health impact of structural racism and social inequities.

Understanding Families as Essential in Psychiatric Practice.

Family work is a critical component of psychiatric practice. It is important for psychiatrists to be able to understand the role of family relationships and family systems in individual development across the lifespan. Assessing family factors is an important part of developing a biopsychosocial formulation. Understanding family relationships provides a context for an individual's values and beliefs, which are important components of assessing the patient's mental health challenges. Dysfunctional family relationships can be precipitating or perpetuating factors for mental illness. On the other hand, positive family relationships can offer support, be protective, alleviate emotional and behavioral problems, and lead to improved outcomes. It is important for psychiatrists to be able to work effectively with families by providing support, understanding families' needs, assessing families' strengths and limitations, identifying issues requiring family-based intervention, and facilitating referral to a family therapist when necessary. By engaging families as resources and essential partners in treatment planning, the psychiatrist is able to enhance the quality and success of patient care. This article discusses the role of the psychiatrist in assessing family factors implicated in psychiatric illness; offers general context for understanding the response required by families for improving various emotional and behavioral challenges; and provides an overview of family-based interventions, including family psychoeducation and support, parent management training, and family therapy.

Hemodialysis using a low bicarbonate dialysis bath: Implications for acid-base homeostasis.

The low bath bicarbonate concentration ([ HCO3- ]) used by a nephrology group in Japan (25.5 mEq/L), coupled with a bath [acetate] of 8 mEq/L, provided an opportunity to study the acid-base events occurring during hemodialysis when HCO3- flux is from the patient to the bath. We used an analytic tool that allows calculation of HCO3- delivery during hemodialysis and the physiological response to it in 17 Japanese outpatients with an average pre-dialysis blood [ HCO3- ] of 25 mEq/L. Our analysis demonstrates that HCO3- addition is markedly reduced and that all of it comes from acetate metabolism. The HCO3- added to the extracellular fluid during treatment (19.5 mEq) was completely consumed by H+ mobilization from body buffers. In contrast to patients dialyzing with higher bath [ HCO3- ] values in the US and Europe, organic acid production was suppressed rather than stimulated. Dietary analysis indicates that these patients are in acid balance due to the alkaline nature of their diet. In a larger group of patients using the same bath solution, pre-dialysis blood [ HCO3- ] was lower, 22.2 mEq/L, but still in an acceptable range. Our studies indicate that a low bath [ HCO3- ] is well tolerated and can prevent stimulation of organic acid production.

Assessing Residents' Skills in Psychiatric Reasoning: the Tufts Test of Formulation and Treatment Planning.

OBJECTIVE: The authors aimed to develop an easily administered and scored written test of clinical reasoning for psychiatry residents and to explore its internal reliability and correlation with parameters of training. METHODS: The authors developed a case-based, multiple-choice test comprising 83 questions related to data gathering and interpretation, diagnosis, hypothesis generation and testing, and treatment planning. Postgraduate years 1-4 residents at 18 diverse residency programs, along with their Program Directors and/or Associate Program Directors, took the test. Outcome measures included internal reliability statistics, performance across levels of training, performance in different test categories, performance in programs with high vs. low emphasis on integrative case formulation, and performance in native English speakers vs. others. RESULTS: A total of 359 residents and 23 faculty members participated. The KR-20 statistic of 0.78 indicated that the test was internally reliable. Faculty performed better than residents, who began to approach faculty level only in their fourth year. Residents in programs with high emphasis on formulation and treatment planning tended to score better than those from low emphasis programs on hypothesis generation and testing, but not other categories of question. There was no evidence that non-native English speakers were at a disadvantage on the test. CONCLUSIONS: A novel test of formulation and treatment planning has met criteria for internal reliability and provided preliminary data about development of reasoning skills in residents. The authors hope that taking and discussing it will also be useful as a training exercise in integrative case formulation.

Changing dialysate composition to optimize acid-base therapy.

In response to rapid alkali delivery during hemodialysis, hydrogen ions (H+ ) are mobilized from body buffers and from stimulation of organic acid production in amounts sufficient to convert most of the delivered bicarbonate to CO2 and water. Release of H+ from nonbicarbonate buffers serves to back-titrate them to a more alkaline state, readying them to buffer acids that accumulate in the interval between treatments. By contrast, stimulation of organic acid production only serves to remove added bicarbonate (HCO3 - ) from the body; the organic anions produced by this process are lost into the dialysate, irreversibly acidifying the patient as well as diverting metabolic activity from normal homeostasis. We have developed an analytic tool to quantify these acid-base events, which has shown that almost two-thirds of the H+ mobilized during hemodialysis comes from organic acid production when bath bicarbonate concentration ([HCO3 - ]) is 32 mEq/L or higher. Using data from the hemodialysis patients we studied with our analytical model, we have simulated the effect of changing bath solute on estimated organic acid production. Our simulations demonstrate that reducing bath [HCO3 - ] should decrease organic acid production, a change we propose as beneficial to the patient. They also highlight the differential effects of variations in bath acetate concentration, as compared to [HCO3 - ], on the amount and rate of alkali delivery. Our results suggest that transferring HCO3 - delivery from direct influx to acetate influx and metabolism provides a more stable and predictable rate of HCO3 - addition to the patient receiving bicarbonate-based hemodialysis. Our simulations provide the groundwork for the clinical studies needed to verify these conclusions.

Acid-base homeostasis during hemodialysis: New insights into the mystery of bicarbonate disappearance during treatment.

In patients receiving hemodialysis, it has long been recognized that much more bicarbonate is delivered during treatment than ultimately appears in the blood. To gain insight into this mystery, we developed a model that allows a quantitative analysis of the patient's response to rapid alkalinization during hemodialysis. Our model is unique in that it is based on the distribution of bicarbonate in the extracellular fluid and assesses its removal from this compartment by mobilization of protons (H+ ) from buffers and other sources. The model was used to analyze the pattern of rise in blood bicarbonate concentration ([HCO3- ]), calculated from measurements of pH and PCO2 , in patients receiving standard bicarbonate hemodialysis. Model analysis demonstrated two striking findings: (1) 35% of the bicarbonate added during hemodialysis was due to influx and metabolism of acetate, despite its low concentration in the bath solution, because of the rapidly collapsing gradient for bicarbonate influx. (2) Almost 90% of the bicarbonate delivered to the patients was neutralized by H+ generation. Virtually all the new H+ came from intracellular sources and included both buffering and organic acid production. The small amount of added bicarbonate retained in the extracellular fluid increased blood [HCO3- ], on average, by 6 mEq/L in our patients. Almost all this rise occurred during the first 2 hours. Thereafter, blood [HCO3- ] changed minimally and always remained less than bath [HCO3- ]. This lack of equilibrium was due to the continued production of organic acid. Release of H+ from buffers is a reversible physiological response, restoring body alkali stores. By contrast, organic acid production is an irreversible process during hemodialysis and is metabolically inefficient and potentially catabolic. Our analysis underscores the need to develop new approaches for alkali repletion during hemodialysis that minimize organic acid production.

Conservation of Mass: An Important Tool in Renal Research.

The dialytic treatment of end-stage renal disease (ESRD) patients is based on control of solute concentrations and management of fluid volume. The application of the principal of conservation of mass, or mass balance, is fundamental to the study of such treatment and can be extended to chronic kidney disease (CKD) in general. This review discusses the development and use of mass conservation and transport concepts, incorporated into mathematical models. These concepts, which can be applied to a wide range of solutes of interest, represent a powerful tool for quantitatively guided studies of dialysis issues currently and into the future. Incorporating these quantitative concepts in future investigations is key to achieving positive control of known solutes, and in the analysis of such studies; to relate future research to known results of prior studies; and to help in the understanding of the obligatory physiological perturbations that result from dialysis therapy.

Examining Trends and Coexisting Conditions Among Children Qualifying for SSI Under ADHD, ASD, and ID.

OBJECTIVE: To examine the prevalence trends and coexisting conditions in attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and intellectual disability (ID) in the pediatric Supplemental Security Income (SSI) population and general population. METHODS: The Social Security Administration (SSA) provided data on primary and secondary diagnoses of children qualifying for SSI for years 2000 to 2011. We compared SSA data with 2000-2011 National Health Interview Survey data on the prevalence of mental health diagnoses among children in the general population living between 0 and 199% of the federal poverty line. We utilized linear regression analysis to test the statistical significance of differences in the trends of the conditions' prevalence. RESULTS: Over this time period, the SSI population experienced increases in ADHD (5.8%) and ASD (7.2%) and a decrease in ID (-10.3%). Comparison with change in the general population indicated no significant difference in ADHD but significant differences in ASD and ID. Relative percentage changes reflect similar changes. The SSI population qualifying for SSI with ADHD (70.8%) had higher rates of coexisting conditions than the general population (66.1%), but lower rates of coexisting conditions for ASD and ID. CONCLUSIONS: ADHD is on the rise among children receiving SSI and in the general population. This suggests that the rise of ADHD in the SSI population is expected and does not represent a misallocation of resources. Changes described among the SSI population in ASD and ID may allude to diagnostic/coding trends and/or true changes in prevalence. Limitations arise from the comparability of the 2 data sets.

Overview of the Evidence Base for Family Interventions in Child Psychiatry.

This article provides updated information about evidence-based family interventions for child and adolescent mental health issues. The article reviews randomized controlled trials for family-based interventions carried out over the last 15 years. The studies were selected from an evidence-based clearinghouse search for family therapy, and specific child and adolescent psychiatric disorders. It is hoped this review guides clinical treatment and encourages clinicians to consider family involvement in treatment. This is specifically necessary when there is a limited response to psychopharmacologic and individual or group psychotherapy treatment.

A South African public-private partnership HIV treatment model: viability and success factors.

INTRODUCTION: The increasing number of people requiring HIV treatment in South Africa calls for efficient use of its human resources for health in order to ensure optimum treatment coverage and outcomes. This paper describes an innovative public-private partnership model which uses private sector doctors to treat public sector patients and ascertains the model's ability to maintain treatment outcomes over time. METHODS: The study used a retrospective design based on the electronic records of patients who were down-referred from government hospitals to selected private general medical practitioners (GPs) between November 2005 and October 2012. In total, 2535 unique patient records from 40 GPs were reviewed. The survival functions for mortality and attrition were calculated. Cumulative incidence of mortality for different time cohorts (defined by year of treatment initiation) was also established. RESULTS: The median number of patients per GP was 143 (IQR: 66-246). At the time of down-referral to private GPs, 13.8% of the patients had CD4 count <200 cell/mm(3), this proportion reduced to 6.6% at 12 months and 4.1% at 48 months. Similarly, 88.4% of the patients had suppressed viral load (defined as HIV-1 RNA <400 copies/ml) at 48 months. The patients' probability of survival at 12 and 48 months was 99.0% (95% CI: 98.4%-99.3%) and 89.0% (95% CI: 87.1%-90.0%) respectively. Patient retention at 48 months remained high at 94.3% (95% CI: 93.0%-95.7%). CONCLUSIONS: The study findings demonstrate the ability of the GPs to effectively maintain patient treatment outcomes and potentially contribute to HIV treatment scale-up with the relevant support mechanism. The model demonstrates how an assisted private sector based programme can be effectively and efficiently used to either target specific health concerns, key populations or serve as a stop-gap measure to meet urgent health needs.

A novel Markov model projecting costs and outcomes of providing antiretroviral therapy to public patients in private practices versus public clinics in South Africa.

INTRODUCTION: Providing private antiretroviral therapy (ART) care for public sector patients could increase access to ART in low- and middle-income countries. We compared the costs and outcomes of a private-care and a public-care ART program in South Africa. METHODS: A novel Markov model was developed from the public-care program. Patients were first tunneled for 6 months in their baseline CD4 category before being distributed into a dynamic CD4 and viral load model. Patients were allowed to return to ART care from loss to follow up (LTFU). We then populated this modeling framework with estimates derived from the private-care program to externally validate the model. RESULTS: Baseline characteristics were similar in the two programs. Clinic visit utilization was higher and death rates were lower in the first few years on ART in the public-care program. After 10 years on ART we estimated the following outcomes in the public-care and private-care programs respectively: viral load <1000 copies/ml 89% and 84%, CD4 >500 cells/µl 33% and 37%, LTFU 14% and 14%, and death 27% and 32%. Lifetime undiscounted survival estimates were 14.1 (95%CI 13.2-14.9) and (95%CI 12.7-14.5) years with costs of 18,734 (95%CI 12,588-14,022) and 13,062 (95%CI 12,077-14,047) USD in the private-care and public-care programs respectively. When clinic visit utilization in the public-care program was reduced by two thirds after the initial 6 months on ART, which is similar to their current practice, the costs were comparable between the programs. CONCLUSIONS: Using a novel Markov model, we determined that the private-care program had similar outcomes but lower costs than the public-care program, largely due to lower visit frequencies. These findings have important implications for increasing and sustaining coverage of patients in need of ART care in resource-limited settings.

Trauma and diverse child populations.

It has been estimated that as many as two-thirds of American youth experience a potentially life-threatening event before 18 years of age and that half have experienced multiple potentially traumatic events. Race, ethnicity, and culture influence the frequency and nature of these traumas and also the ways in which children react to traumatic events. The authors discuss the varied influences of cultural background on these reactions to trauma, the varying presentations of diverse children experiencing troubling reactions, and the need to provide treatment to children and their families in a fashion that is culturally sensitive and acceptable to diverse families.
