Intravenous Levothyroxine for Unstable Brain-Dead Heart Donors.

BACKGROUND: Hemodynamic instability and myocardial dysfunction are major factors preventing the transplantation of hearts from organ donors after brain death. Intravenous levothyroxine is widely used in donor care, on the basis of observational data suggesting that more organs may be transplanted from donors who receive hormonal supplementation. METHODS: In this trial involving 15 organ-procurement organizations in the United States, we randomly assigned hemodynamically unstable potential heart donors within 24 hours after declaration of death according to neurologic criteria to open-label infusion of intravenous levothyroxine (30 µg per hour for a minimum of 12 hours) or saline placebo. The primary outcome was transplantation of the donor heart; graft survival at 30 days after transplantation was a prespecified recipient safety outcome. Secondary outcomes included weaning from vasopressor therapy, donor ejection fraction, and number of organs transplanted per donor. RESULTS: Of the 852 brain-dead donors who underwent randomization, 838 were included in the primary analysis: 419 in the levothyroxine group and 419 in the saline group. Hearts were transplanted from 230 donors (54.9%) in the levothyroxine group and 223 (53.2%) in the saline group (adjusted risk ratio, 1.01; 95% confidence interval [CI], 0.97 to 1.07; P = 0.57). Graft survival at 30 days occurred in 224 hearts (97.4%) transplanted from donors assigned to receive levothyroxine and 213 hearts (95.5%) transplanted from donors assigned to receive saline (difference, 1.9 percentage points; 95% CI, -2.3 to 6.0; P<0.001 for noninferiority at a margin of 6 percentage points). There were no substantial between-group differences in weaning from vasopressor therapy, ejection fraction on echocardiography, or organs transplanted per donor, but more cases of severe hypertension and tachycardia occurred in the levothyroxine group than in the saline group. CONCLUSIONS: In hemodynamically unstable brain-dead potential heart donors, intravenous levothyroxine infusion did not result in significantly more hearts being transplanted than saline infusion.

The benefits of initiating continuous renal replacement therapy after brain death in organ donors with oligoanuric acute kidney injury.

Acute kidney injury (AKI) in deceased organ donors is increasing due to the escalation in anoxic brain-deaths. The management of an organ donor with oligoanuric AKI is frequently curtailed due to hemodynamic and electrolyte instability. Although continuous renal replacement therapy (CRRT) corrects the effects of AKI, it is rarely started after the diagnosis of brain-death (BD). Since 2017, we have initiated CRRT in organ donors with oligoanuric AKI to allow more time to stabilize the donor and improve the function of the thoracic organs. We now report our experience with the first 27 donors with oligoanuric AKI that received CRRT after the diagnosis of BD, with organs transplanted as the primary outcome. The average duration of CRRT was 30.1 ± 14.4 h and the mean ultrafiltration volume was 5141 ± 4272 ml. The time from BD declaration to cross clamp was significantly longer in the CRRT group versus a historical cohort with oligoanuric AKI that was not dialyzed (62.8 ± 18.3 vs. 37.1 ± 14.9 h; P < .01). The mean number of total organs transplanted per donor in the CRRT group was greater than the historical cohort, 2.9 ± 1.7 vs. 1.4 ± .6 (P = .< 01), respectively. The mean number of thoracic organs transplanted per donor also increased between the two groups, 1.4 ± 1.2 versus .6 ± .9 (P = .02). Thirty-seven percent of the kidneys were successfully transplanted with a mean serum creatinine of 1.4 mg/dl at 6 months. We suggest that OPOs consider starting CRRT in organ donors with oligoanuric AKI to possibly increase the number of organs transplanted.

Validity of the Johns Hopkins Fall Risk Assessment Tool for Predicting Falls on Inpatient Medicine Services.

The Johns Hopkins Fall Risk Assessment Tool (JHFRAT) is widely used but few studies have examined its psychometric properties. We examined the predictive validity of the JHFRAT for 13 574 patient admissions to medicine units at a large academic medical center in 2014. There were 204 patient falls reported. While patients who fell had higher JHFRAT total scores, a majority of patients who fell were classified by the JHFRAT as moderate or low risk.

The benefits of integrating a statistician into a nursing research department.

In today's competitive healthcare market, more hospitals are seeking Magnet® designation. To meet the expectations for evidence-based practice and research, many organizations are considering the addition of statistical expertise to their team. The authors discuss the benefits of analytical support and integration of a statistician on the team.

Patient satisfaction and organizational impact: a hierarchical linear modeling approach.

This article presents the rationale for using multilevel analysis to address the broad environmental contexts in patient satisfaction research. This study utilized patient satisfaction data and the American Hospital Association Hospital Guide Book (2004). This study found significant contributions of individual patient attribute reactions (nursing care, physician care, etc.), and also clearly demonstrated hospital-level effects and cross-level interactions on patient satisfaction. Thus, it is clear that patient satisfaction is not solely explained by patients' attribute reactions and their demographic variables, but is also explained by patients' hospital levels. This approach would offer additional understanding in patient satisfaction research.

Inpatients' willingness to recommend: a multilevel analysis.

BACKGROUND: Satisfaction with health care is one of the most widely assessed measures of hospital care quality, yet studies that account for clustering effects are uncommon. We constructed a multilevel model to identify predictors of willingness to recommend while controlling for clustering effects due to hospital and care unit. We also examined differences in predictors by care unit. PURPOSE: The aim of this study was to identify factors that both influence patient perceptions of care and are potentially modifiable by the hospital delivering care. METHODOLOGY: Our sample includes Hospital Consumer Assessment of Healthcare Providers and Systems survey data collected between July 1, 2007, and June 30, 2008, for 131 hospitals and 33,445 patients. The primary outcome was willingness to recommend the hospital to family and friends. Variables were collected at three levels: patient (Hospital Consumer Assessment of Healthcare Providers and Systems survey item responses and demographics), care unit, and hospital. Data were analyzed using multilevel modeling. We also ran a series of two-level models to explore differences in predictors by care type. FINDINGS: The strongest predictors of willingness to recommend, controlling for clustering effects, were items that generally reflected interpersonal aspects of care such as nursing and physician behaviors. In the two-level models, predictors of willingness to recommend overlapped across care units, but important differences were noted. PRACTICE IMPLICATIONS: Our results suggest that hospitals that wish to improve their performance would benefit most from focusing on interpersonal aspects of care. Hospitals that focus resources on improving in these areas, that assess care units separately, and that investigate the meaning and context of survey responses will be most likely to see improvements in satisfaction scores.

Who's in and who's out: use of primary medical care among people living with HIV.

OBJECTIVES: We sought to achieve a more comprehensive picture of access to medical care for the treatment of HIV (HIV primary care) by combining evidence of medical services used (health utilization) and epidemiological client-level data. METHODS: This study integrated health information from several data sources to measure utilization of HIV primary care in the St Louis, Mo, area between 1998 and 2002. Data from disparate HIV health utilization databases were combined with data from the Missouri HIV and AIDS Reporting System database and then deidentified to measure client-level utilization of HIV primary care over time. RESULTS: About half of those with HIV showed evidence of having utilized HIV primary care in a given year. Although most of this group utilized HIV primary care in the first year after they received their HIV diagnosis, evidence of subsequent utilization was inconsistent. Utilization of primary care was most strongly associated with an AIDS diagnosis. About one quarter of people diagnosed with HIV after 1997 had an AIDS diagnosis when they first tested positive for HIV. CONCLUSIONS: This study was the first of its kind to integrate several databases to understand HIV primary health care utilization over a period of years. Our findings reinforce the importance of CD4 and viral load values as indicators of utilization of HIV primary health care, particularly in the absence of other health data sets. The lack of available data and the way in which source data were available limited the study.

Client outcomes and the working alliance in the client-case manager relationship: a causal analysis.

This study investigated the causal relationship between the working alliance and client outcomes in the client-case manager relationship. All 162 study participants received services fiom a case manager who worked as a member of an assertive community treatment team. All participants had both a substance use disorder and a diagnosis of severe mental illness and were homeless at baseline. A brief form of the Working Alliance Inventory (WAI) was used to measure the working alliance after 3 and 15 months of treatment. The Brief Psychiatric Rating Scale was used to measure psychiatric symptoms at baseline, 9, and 18 months. Days per month that clients used alcohol or illegal drugs was also assessed at baseline, 9, and 18 months. The data were analyzed using structural equation modeling (SEM). The correlations between the working alliance and the outcome measures were lower than similar correlations obtained in studies investigating the psychotherapy relationship. The SEM analyses revealed little or no causal relationship between the working alliance and client outcome in this sample.

Retrospective review of postoperative glycemic control in patients after distal pancreatectomy.

BACKGROUND: Distal pancreatectomy (DP) is carried out for resection of lesions in the body and tail of the pancreas. DP may lead to both insulin and glucagon deficiency, which may worsen diabetes mellitus and render patients more vulnerable to severe hypoglycemia. Maintaining glycemic control can be challenging after DP, and no guidelines have been established for clinicians. The objective of this study was to investigate postoperative glycemic control and insulin dose among patients after DP. METHODS: The medical records from 82 eligible adult patients after DP between 2013 and 2014 were reviewed retrospectively. RESULTS: Twenty-one (25.6%) patients had pre-existing diabetes. The average length of stay was 5.8 ± 2.6 days. The average resected volume was 193 ± 313 cm3. Of 2124 blood glucose (BG) values, only 0.3% were <70 mg/dL (3.9 mmol/L); 45% were 140-180 mg/dL (7.8-10.0 mmol/L); and 14% were >180 mg/dL. Postoperatively, insulin was the most common agent prescribed for glycemic control. Among those who received insulin, 86.8% used rapid-acting correction insulin, 4.4% prandial insulin, and 8.8% long-acting insulin. On postoperative day 1 through 6 and on the day before hospital discharge, <30% of patients received insulin, and a total daily dose (TDD) of <0.10 units/kg was frequently needed for glycemic control. At discharge, 35.3% of patients with pre-existing diabetes improved; 23.2% required diabetic medications, of whom 50% took insulin. Only 2 patients without pre-existing diabetes required medications. CONCLUSION: Postoperative BG levels were relatively well controlled. The majority of BG levels were in the optimal range, and the incidence of hypoglycemia or clinically significant hypoglycemia was minimal with our current regimen. Postoperative patients required small TDD of insulin for glycemic control. Our data suggested that 0.05-0.20 units/kg was an appropriate dose range for postoperative glycemic control among the vulnerable population. Our findings provide guidance for clinicians to dose insulin safely for postoperative patients with DP in a hospital setting.

Detecting and Managing Diabetes Mellitus and Prediabetes in Patients With Acute Stroke.

PURPOSE: The purpose of the study was to determine the prevalence of undiagnosed diabetes mellitus (DM) and prediabetes (pre-DM) in acute stroke patients, to evaluate recommendations of diabetes treatment and follow-up care in a hospital setting, and to examine 1-year readmission rates based on admission A1C measure. METHODS: This retrospective study comprised 200 patients randomly selected from 1095 patients admitted with an acute stroke and an A1C measurement during admission. DM and pre-DM prevalence levels were determined per A1C level. Recommendations for diabetes treatment during and after hospitalization were assessed; charts were reviewed for readmission. RESULTS: Among 200 patients, 43% had known DM, and 0.5% had pre-DM. Among 113 patients without history of DM or pre-DM, 61.9% had A1C 5.7% to 6.4% (39-46 mmol/mol), and 8.8% had A1C ≥6.5% (48 mmol/mol). None of the newly diagnosed pre-DM and 60% of newly diagnosed DM were documented. Only 7 of newly diagnosed DM or pre-DM patients received diabetes education. For patients with known DM and A1C ≥7.0% (53 mmol/mol), 40.5% registered no change of diabetic regimen. Few patients were recommended for diabetes follow-up care. Patients with A1C ≥6.5% or <5.7% were more likely to be readmitted for any reason within 1 year (33.3% and 31.6%, respectively) than patients with A1C levels of 5.7% to 6.4% (16.5%). CONCLUSIONS: The majority of acutely admitted stroke patients without known DM or pre-DM had A1C ≥5.7%. Newly diagnosed DM or pre-DM patients received inadequate diabetes education and follow-up care. These findings provide significant opportunities for improving acute stroke management.

Mental health case management as a locus for HIV prevention: results from case-manager focus groups.

HIV infection among people with severe mental illness (SMI) is a growing concern, and interventions have been designed to address HIV prevention among these individuals. However, little is known about the preparedness of mental health providers to support these interventions. This study concentrated on mental health case management as a locus for HIV-prevention services. Focus groups of case managers were conducted to learn participants' motivation to adopt HIV-prevention services and barriers/facilitators to such adoption. Participants reported they would be motivated to offer HIV prevention if services were to be presented in the context of existing client relationships and case-management tasks. Barriers and facilitators were discussed at client, provider, and community levels, and recommendations for training were offered. Findings have implications for diffusion of HIV-prevention services in case management, and the line of questioning in focus groups provides a basis for learning about other behavioral health service contexts as loci for disease prevention.

Evaluation of treatment programs for persons with severe mental illness: moderator and mediator effects.

This study evaluated several statistical models for estimating treatment effects in a randomized, longitudinal experiment comparing assertive community treatment (ACT) versus brokered case management (BCM). In addition, mediator and moderator analyses were conducted. The ACT clients had improved outcomes in terms of housing and psychiatric symptoms than BCM clients. Case management housing assistance and financial assistance partially mediated housing outcomes. No reliable mediators were found for psychiatric symptoms, and no reliable moderators were found for either housing or psychiatric symptoms. The study also made several important methodological advances in the analysis of longitudinal data in randomized experiments.

The case manager's view of the helping alliance.

Although the helping alliance has been a topic of investigation in psychotherapy research for decades, few studies have examined the role of the helping alliance in assertive community treatment programs serving people with severe mental illness. In this article, we describe a series of analyses focused on the case manager's view of the helping alliance. The study addressed two primary questions: What factors facilitate a positive helping alliance in case management? What is the relationship of the helping alliance to client outcomes? Results indicated that few client variables predicted the helping alliance. Providing a wider range of services was associated with a stronger alliance at months but not at 18 months. A strong alliance at 18 months was associated with a strong alliance at 6 months. In addition, the alliance at 18 months was rated more positively for clients who were African-American and who did not have a substance use disorder. The helping alliance predicted client satisfaction, anxiety-depression, and hostility-suspicion outcomes at 6 months. However, the helping alliance did not predict any of the client outcome variables at 18 months.

Client outcomes and the working alliance in assertive community treatment programs.

This study examined the relationship between outcomes and the working alliance in clients who were receiving assertive community treatment only or integrated assertive community treatment (assertive community treatment plus substance abuse treatment). All 98 participants had a severe mental illness and a substance use disorder. The Working Alliance Inventory assessed the alliance from the perspective of both the client and the case manager at 3 and 15 months into treatment. The six outcome measures were stable housing, client rating of psychiatric distress, interviewer rating of psychiatric symptoms, self-report of days used alcohol or drugs, and interviewer rating of substance use. Only 4 of 24 correlations were significant, indicating little relationship between the strength of the working alliance and client outcome.

Evaluation of treatment programs for dual disorder individuals: modeling longitudinal and mediation effects.

This study evaluated the effectiveness of the three approaches for treating dual disorder clients who were homeless at intake: integrated assertive community treatment (IACT), assertive community treatment only (ACTO), and standard care (SC). Multilevel Random Coefficient Modeling (MRCM) was used to analyze longitudinal effects and to identify mediators of significant treatment effects. The outcome variables were consumer satisfaction, stable housing, psychiatric symptoms, and substance abuse. The eight mediators were service utilization variables: program contacts, phone contacts, substance abuse contacts, assistance with activities of daily living, transportation assistance, help finding permanent housing, help with emotional problems, and medication assistance. The 191 eligible participants were randomly assigned to one of the three conditions and followed for a period of 30 months. Both ACTO and IACT produced better outcomes than SC on consumer satisfaction and stable housing. There were no differences on any of the outcome variables between ACTO versus IACT when comparing main effects. However, there were several treatment by time interactions. In addition, there were many mediation effects.

Impact of assertive community treatment and client characteristics on criminal justice outcomes in dual disorder homeless individuals.

BACKGROUND: People with severe mental illness and substance use disorders (dual disorder) often have considerable contact with the criminal justice system. AIMS: To test the effects of client characteristics on six criminal justice outcomes among homeless (at intake) people with mental illness and substance misuse disorders. METHODS: The sample was of participants in a randomized controlled trial comparing standard treatment, assertive community treatment (ACT) and integrated treatment (IT). Data were analysed using hierarchical logistic regression. RESULTS: Half the sample was arrested and a quarter incarcerated during the two-year follow-up period. The regression models explained between 22% and 35% of the variance of the following criminal justice measures: (1) major offences, (2) minor offences, (3) substance-use-related offences, (4) incarcerations, (5) arrests, and (6) summons. Prior criminal behaviour was the strongest predictor of all of the dependent variables; in general, demographic and diagnostic variables were not. Similarly, neither the type nor the amount of mental health treatment received predicted subsequent criminal behaviour. CONCLUSION: Elsewhere the authors have shown that ACT and IT had advantages for health and stability of accommodation but these analyses suggest that more specialized interventions are needed to reduce criminal behaviour in dual disorder individuals.

Moderators and mediators of client satisfaction in case management programs for clients with severe mental illness.

This randomized experiment first determined that clients with severe mental illness who received Assertive Community Treatment (ACT) were more satisfied with their treatment program than were clients in a brokered case management program (BCM). Eight demographic and diagnostic variables were examined as potential moderators of the treatment effect. Only one of the eight varables, diagnosis of depression, interacted with treatment condition to effect client satisfaction. However, there were several important mediators of client satisfaction: intensity of program contacts, continuity of program contacts, supportive services (i.e, assistance with activities of daily living), and the strength of the helping alliance as perceived by the client.

Prevalence of human immunodeficiency virus, hepatitis B, and hepatitis C among homeless persons with co-occurring severe mental illness and substance use disorders.

This study was undertaken to determine the prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) among homeless persons with co-occurring severe mental illness (SMI) and substance use disorders and to determine associated risk factors. As part of a longitudinal study of the effectiveness of integrated treatment for homeless persons with SMI and substance abuse or dependence, serological testing was performed to ascertain the prevalence of HIV, HBV, and HCV. At baseline, 6.2% of participants (11/172) were HIV-positive. Nearly one third of participants (37/114) had evidence of prior exposure to HBV, and 30% (34/114) were antibody positive for HCV. About 44% of participants (50/114) had a reactive test for either HBV or HCV. Having a reactive test was strongly associated with substance use, especially with a history of injection drug use. A significant threat exists to the health and well-being of homeless person with SMI due to high prevalence of blood-borne pathogens. Mental health providers need to play a proactive role in the identification of health-related needs and to assist with access to general health services for persons with SMI.
