RESUMO

OBJECTIVES: Many survivors of sepsis suffer long-term cognitive impairment, but the mechanisms of this association remain unknown. The objective of this study was to determine whether sepsis is associated with cerebral microinfarcts on brain autopsy. DESIGN: Retrospective cohort study. SETTING AND SUBJECTS: Five-hundred twenty-nine participants of the Adult Changes in Thought, a population-based prospective cohort study of older adults carried out in Kaiser Permanente Washington greater than or equal to 65 years old without dementia at study entry and who underwent brain autopsy. MEASUREMENTS AND MAIN RESULTS: Late-life sepsis hospitalization was identified using administrative data. We identified 89 individuals with greater than or equal to 1 sepsis hospitalization during study participation, 80 of whom survived hospitalization and died a median of 169 days after discharge. Thirty percent of participants with one or more sepsis hospitalization had greater than two microinfarcts, compared with 19% participants without (χ p = 0.02); 20% of those with sepsis hospitalization had greater than two microinfarcts in the cerebral cortex, compared with 10% of those without (χ p = 0.01). The adjusted relative risk of greater than two microinfarcts was 1.61 (95% CI, 1.01-2.57; p = 0.04); the relative risk for having greater than two microinfarcts in the cerebral cortex was 2.12 (95% CI, 1.12-4.02; p = 0.02). There was no difference in Braak stage for neurofibrillary tangles or consortium to establish a registry for Alzheimer's disease score for neuritic plaques between, but Lewy bodies were less significantly common in those with sepsis. CONCLUSIONS: Sepsis was specifically associated with moderate to severe vascular brain injury as assessed by microvascular infarcts. This association was stronger for microinfarcts within the cerebral cortex, with those who experienced severe sepsis hospitalization being more than twice as likely to have evidence of moderate to severe cerebral cortical injury in adjusted analyses. Further study to identify mechanisms for the association of sepsis and microinfarcts is needed.

RESUMO

Swallowing evaluations are often delayed at least 24 h following extubation with the assumption that swallow function improves over time. The purpose of this prospective cohort study was to determine if dysphagia, as measured by aspiration and need for diet modification, declines over the first 24-h post-extubation, whereby providing evidence-based evaluation guidelines for this population. Forty-nine patients completed FEES at 2-4 h post-extubation and 24-26 h post-extubation. We compared Penetration-Aspiration Scale scores and diet recommendation between time points. Multivariable logistic regression models were created to investigate associations between age, reason for admission, reason for intubation, and a history of COPD and outcomes of aspiration or silent aspiration at either FEES exam. Sixty-nine percent of participants safely swallowed at least one texture without aspiration at 2-4 h post-extubation. Within participants, there was a significant decrease in penetration/aspiration at 24 h and 79% showed improvement in airway protection on at least one bolus type, suggesting an improvement in swallow function over the first day following extubation. These findings suggest that although patients may be safe to begin a modified diet soon after extubation, delaying evaluation until 24-h post-extubation may allow for a less restricted diet.

RESUMO

OBJECTIVE: Severe sepsis survivors frequently experience cognitive and physical functional impairment. The degree of impairment and its association with mortality is understudied, particularly among those discharged to a skilled nursing facility. Our objective was to quantify the cognitive and physical impairment among severe sepsis survivors discharged to a skilled nursing facility and to investigate the relationship between impairment and long-term mortality. DESIGN: Retrospective cohort study. SETTING: United States. SUBJECTS: Random 5% sample of Medicare patients discharged following severe sepsis hospitalization, 2005-2009 (n = 135,370). MEASUREMENT AND MAIN RESULTS: Medicare data were linked with the Minimum Data Set; Minimum Data Set-Cognition Scale was used to assess cognitive function, and the Minimum Data Set activities of daily living hierarchical scale was used to assess functional dependence. Associations were evaluated using multivariable logistic regression, Kaplan-Meier curves, and Cox proportional hazards regression. Of 66,540 beneficiaries admitted to a skilled nursing facility following severe sepsis, 34% had severe or very severe cognitive impairment, and 72.5% had maximal, dependence, or total dependence in activities of daily living. Median survival was 19.4 months for those discharged to a skilled nursing facility without having been in a skilled nursing facility in the preceding 1 year and 10.4 months for those discharged to a skilled nursing facility who had spent time in a skilled nursing facility in the prior year. The adjusted hazard ratio for death was 3.1 for those with very severe cognitive impairment relative to those who were cognitively intact (95% CI, 2.9-3.2; p < 0.001) and 4.3 for those with "total dependence" in activities of daily livings relative to those who were independent (95% CI, 3.8-5.0; p < 0.001). CONCLUSIONS: Discharge to a skilled nursing facility following severe sepsis hospitalization among Medicare beneficiaries was associated with shorter survival, and cognitive impairment and activities of daily living dependence were each strongly associated with shortened survival. These findings can inform decision-making by patients and physicians and underscores high palliative care needs among sepsis survivors discharged to skilled nursing facility.

RESUMO

OBJECTIVES: Surgical patients often receive routine postoperative mechanical ventilation with excellent outcomes. However, older patients who receive prolonged mechanical ventilation may have a significantly different long-term trajectory not fully captured in 30-day postoperative metrics. The objective of this study is to describe patterns of mortality and hospitalization for Medicare beneficiaries 66 years old and older who have major surgery with and without prolonged mechanical ventilation. DESIGN: Retrospective cohort study. SETTING: Hospitals throughout the United States. PATIENTS: Five percent random national sample of elderly Medicare beneficiaries (age ≥ 66 yr) who underwent 1 of 227 operations previously defined as high risk during an inpatient stay at an acute care hospital between January 1, 2005, and November 30, 2009. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We identified 117,917 episodes for older patients who had high-risk surgery; 4% received prolonged mechanical ventilation during the hospitalization. Patients who received prolonged mechanical ventilation had higher 1-year mortality rate than patients who did not have prolonged ventilation (64% [95% CI, 62-65%] vs 17% [95% CI, 16.4-16.9%]). Thirty-day survivors who received prolonged mechanical ventilation had a 1-year mortality rate of 47% (95% CI, 45-48%). Thirty-day survivors who did not receive prolonged ventilation were more likely to be discharged home than patients who received prolonged ventilation 71% versus 10%. Patients who received prolonged ventilation and were not discharged by postoperative day 30 had a substantially increased 1-year mortality (adjusted hazard ratio, 4.39 [95% CI, 3.29-5.85]) compared with patients discharged home by day 30. Hospitalized 30-day survivors who received prolonged mechanical ventilation and died within 6 months of their index procedure spent the majority of their remaining days hospitalized. CONCLUSIONS: Older patients who require prolonged mechanical ventilation after high-risk surgery and survive 30 days have a significant 1-year risk of mortality and high burdens of treatment. This difficult trajectory should be considered in surgical decision making and has important implications for surgeons, intensivists, and patients.

RESUMO

PURPOSE: To perform a systematic review and meta-analysis of all published studies since 2005 that evaluate the accuracy of magnetic resonance imaging (MRI) for the diagnosis of acute appendicitis in the general population presenting to emergency departments. MATERIALS AND METHODS: All retrospective and prospective studies evaluating the accuracy of MRI to diagnose appendicitis published in English and listed in PubMed, Web of Science, Cinahl Plus, and the Cochrane Library since 2005 were included. Excluded studies were those without an explicitly stated reference standard, with insufficient data to calculate the study outcomes, or if the population enrolled was limited to pregnant women or children. Data were abstracted by one investigator and confirmed by another. Data included the number of true positives, true negatives, false positives, false negatives, number of equivocal cases, type of MRI scanner, type of MRI sequence, and demographic data including study setting and gender distribution. Summary test characteristics were calculated. Forest plots and a summary receiver operator characteristic plot were generated. RESULTS: Ten studies met eligibility criteria, representing patients from seven countries. Nine were prospective and two were multicenter studies. A total of 838 subjects were enrolled; 406 (48%) were women. All studies routinely used unenhanced MR images, although two used intravenous contrast-enhancement and three used diffusion-weighted imaging. Using a bivariate random-effects model the summary sensitivity was 96.6% (95% confidence interval [CI]: 92.3%-98.5%) and summary specificity was 95.9% (95% CI: 89.4%-98.4%). CONCLUSION: MRI has a high sensitivity and specificity for the diagnosis of appendicitis, similar to that reported previously for computed tomography. J. Magn. Reson. Imaging 2016;43:1346-1354.

RESUMO

OBJECTIVE: To determine whether clinical scoring systems or physician gestalt can obviate the need for computed tomography (CT) in patients with possible appendicitis. METHODS: Prospective, observational study of patients with abdominal pain at an academic emergency department (ED) from February 2012 to February 2014. Patients over 11 years old who had a CT ordered for possible appendicitis were eligible. All parameters needed to calculate the scores were recorded on standardised forms prior to CT. Physicians also estimated the likelihood of appendicitis. Test characteristics were calculated using clinical follow-up as the reference standard. Receiver operating characteristic curves were drawn. RESULTS: Of the 287 patients (mean age (range), 31 (12-88) years; 60% women), the prevalence of appendicitis was 33%. The Alvarado score had a positive likelihood ratio (LR(+)) (95% CI) of 2.2 (1.7 to 3) and a negative likelihood ratio (LR(-)) of 0.6 (0.4 to 0.7). The modified Alvarado score (MAS) had LR(+) 2.4 (1.6 to 3.4) and LR(-) 0.7 (0.6 to 0.8). The Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) score had LR(+) 1.3 (1.1 to 1.5) and LR(-) 0.5 (0.4 to 0.8). Physician-determined likelihood of appendicitis had LR(+) 1.3 (1.2 to 1.5) and LR(-) 0.3 (0.2 to 0.6). When combined with physician likelihoods, LR(+) and LR(-) was 3.67 and 0.48 (Alvarado), 2.33 and 0.45 (RIPASA), and 3.87 and 0.47 (MAS). The area under the curve was highest for physician-determined likelihood (0.72), but was not statistically significantly different from the clinical scores (RIPASA 0.67, Alvarado 0.72, MAS 0.7). CONCLUSIONS: Clinical scoring systems performed equally well as physician gestalt in predicting appendicitis. These scores do not obviate the need for imaging for possible appendicitis when a physician deems it necessary.

RESUMO

OBJECTIVE: To evaluate emergency department patients' knowledge of radiation exposure and subsequent risks from computed tomography (CT) and magnetic resonance imaging (MRI) scans. METHODS: This is a cross-sectional survey study of adult, English-speaking patients from June to August 2011 at 2 emergency departments--1 academic and 1 community-based--in the upper Midwest. The survey consisted of 2 sets of 3 questions evaluating patients' knowledge of radiation exposure from medical imaging and subsequent radiation-induced malignancies and was based on a previously published survey. The question sets paralleled each other, but one pertained to CT and the other to MRI. Questions in the survey ascertained patients' understanding of (1) the relative amount of radiation exposed from CT/MRI compared with a single chest x-ray; (2) the relative amount of radiation exposed from CT/MRI compared with a nuclear power plant accident; and (3) the possibility of radiation-induced malignancies from CT/MRl. Sociodemographic data also were gathered. The primary outcome measure was the proportion of correct answers to each survey question. Multiple logistic regression then was used to examine the relationship between the percentage correct for each question and sociodemographic variables, using odds ratios with 95% confidence intervals. P-values less than 0.05 were considered statistically significant. RESULTS: There were 500 participants in this study, 315 from the academic center and 185 from the community hospital. Overall, 14.1% (95% CI, 11.0%-17.2%) of participants understood the relative radiation exposure of a CT scan compared with a chest x-ray, while 22.8% (95% CI, 18.9%-26.7%) of respondents understood the lack of ionizing radiation use with MRI. At the same time, 25.6% (95% CI, 21.8%- 29.4%) believed that there was an increased risk of developing cancer from repeated abdominal CTs, while 55.6% (95% CI, 51.1%-60.1%) believed this to be true of abdominal MRI. Higher educational level and identification as a health care professional were associated with correct responses. However, even within these groups, a significant majority gave incorrect responses to all questions. CONCLUSION: Patients did not demonstrate understanding of the degree of radiation exposure from CT scans and the subsequent risks associated with this exposure, namely radiation-induced malignancies. Moreover, they did not understand that MRI scans do not expose them to ionizing radiation and therefore lack this downstream effect. While patient preference is integral to patient-centered care, physicians should be aware of the significant lack of knowledge as it pertains to the selection of medical imaging tests.

RESUMO

OBJECTIVES: The objective of this study was to determine the characteristics and survival rates of patients receiving cardiopulmonary resuscitation more than once during a single hospitalization. DESIGN: We analyzed inpatient Medicare data from 1992 to 2005 identifying beneficiaries 65 years old and older who underwent cardiopulmonary resuscitation more than once during the same hospitalization. MEASUREMENTS: We examined patient and hospital characteristics, survival to hospital discharge, factors associated with survival to discharge, median survival, and discharge disposition. RESULTS: We analyzed data from 421,394 patients who underwent cardiopulmonary resuscitation during the study period. Four lakh thirteen thousand four hundred three patients received cardiopulmonary resuscitation once during a hospitalization and survival was 17.7% with median survival after discharge being 20.6 months. There were 7,991 patients who received cardiopulmonary resuscitation more than once during the same hospitalization; 8.8% survived the efforts, and median survival after leaving the hospital was 10.5 months. Patients who received more than one episode of cardiopulmonary resuscitation during a hospitalization were significantly less likely to go home after discharge. Greater age, black race, higher burden of chronic illness, and receiving cardiopulmonary resuscitation in a larger or metropolitan hospital were associated with lower survival among patients receiving cardiopulmonary resuscitation more than once. CONCLUSIONS: Undergoing multiple cardiopulmonary resuscitation events during a hospitalization is associated with substantially reduced short- and long-term survival compared with patients who undergo cardiopulmonary resuscitation once. This information may be useful to clinicians when discussing end-of-life care with patients and families of patients who have experienced return of spontaneous circulation following in-hospital cardiopulmonary resuscitation but remain at risk for recurrent cardiac arrest.

RESUMO

There are a number of studies providing evidence that age is associated with treatment decisions for critically ill adults, although most of these studies have been unable to fully account for both prehospital health status and severity of acute illness. In the previous issue of Critical Care, Turnbull and colleagues present a well-executed study analyzing data from a prospective cohort study of critically ill patients with acute respiratory distress syndrome to investigate the association between age and new limitations in life-sustaining therapy. They report a strong association between age and new limitations in life support in this cohort, even after adjusting for comorbidities, prehospital functional status, and severity of illness including daily organ dysfunction scores. Their results demonstrate that decisions about the goals of care and the ongoing use of life-sustaining treatments should be viewed as dynamic and responsive to events occurring during critical illness. This study raises the important question about the contributors to this association, and the authors raise the possibility that physician or surrogate bias may be contributing to decisions for older patients. While this is unlikely to be the only contributor to the association between age and end-of-life decisions, the mere possibility should prompt reflection on the part of clinicians caring for critically ill patients.

RESUMO

BACKGROUND: It is unknown whether the rate of survival after in-hospital cardiopulmonary resuscitation (CPR) is improving and which characteristics of patients and hospitals predict survival. METHODS: We examined fee-for-service Medicare data from 1992 through 2005 to identify beneficiaries 65 years of age or older who underwent CPR in U.S. hospitals. We examined temporal trends in the incidence of CPR and the rate of survival after CPR, as well as patient- and hospital-level predictors of survival to discharge. RESULTS: We identified 433,985 patients who underwent in-hospital CPR; 18.3% of these patients (95% confidence interval [CI], 18.2 to 18.5) survived to discharge. The rate of survival did not change substantially during the period from 1992 through 2005. The overall incidence of CPR was 2.73 events per 1000 admissions; the incidence was higher among black and other nonwhite patients. The proportion of patients undergoing in-hospital CPR before death increased over time and was higher for nonwhite patients. The survival rate was lower among patients who were men, were older, had more coexisting illnesses, or were admitted from a skilled-nursing facility. The adjusted odds of survival for black patients were 23.6% lower than those for similar white patients (95% CI, 21.2 to 25.9). The association between race and survival was partially explained by hospital effects: black patients were more likely to undergo CPR in hospitals that have lower rates of post-CPR survival. Among patients surviving in-hospital CPR, the proportion of patients discharged home rather than to a health care facility decreased over time. CONCLUSIONS: Survival after in-hospital CPR did not improve from 1992 through 2005. The proportion of in-hospital deaths preceded by CPR increased, whereas the proportion of survivors discharged home after undergoing CPR decreased. Black race was associated with higher rates of CPR but lower rates of survival after CPR.

RESUMO

RATIONALE: The proportion of low and very low birth weight births is increasing. Infants and children with a history of low and very low birth weight have an increased risk of respiratory illnesses, but it is unknown if clinically significant disease persists into adulthood. OBJECTIVES: To determine if a history of low birth weight is associated with hospitalization for respiratory illness in adulthood. METHODS: This study was a population-based, case-control study. Cases were adults 18 to 27 years of age who were hospitalized for a respiratory illness from 1998 to 2007 within Washington State who could be linked to a Washington State birth certificate for the years 1980 to 1988. Four control subjects, frequency matched by birth year, were randomly selected from Washington State birth certificates for each case patient. Control subjects who died before age 18 were excluded. MEASUREMENTS AND MAIN RESULTS: Two levels of exposure were identified: (1) very low birth weight (birth weight <1,500 g) and (2) moderately low birth weight (birth weight, 1,500-2,499 g). Normal birth weight individuals (2,500-4,000 g) were considered unexposed. Respiratory hospitalizations were defined using discharge diagnosis codes. Logistic regression was used to calculate the odds ratio for hospitalization comparing exposed and unexposed individuals. A total of 4,674 case patients and 18,445 control subjects were identified. The odds ratio for hospitalization for respiratory illness was 1.83 for very low birth weight (95% confidence interval, 1.28-2.62; P = 0.001) and 1.34 for moderately low birth weight (95% confidence interval, 1.17-1.53; P < 0.0005). This association remained after adjustment for birth year, sex, maternal age, race, residence, and marital status. CONCLUSIONS: Adults with a history of very low birth weight or moderately low birth weight were at increased risk of hospitalization for respiratory illness.

RESUMO

CONTEXT: Studies suggest that many survivors of critical illness experience long-term cognitive impairment but have not included premorbid measures of cognitive functioning and have not evaluated risk for dementia associated with critical illness. OBJECTIVES: To determine whether decline in cognitive function was greater among older individuals who experienced acute care or critical illness hospitalizations relative to those not hospitalized and to determine whether the risk for incident dementia differed by these exposures. DESIGN, SETTING, AND PARTICIPANTS: Analysis of data from a prospective cohort study from 1994 through 2007 comprising 2929 individuals 65 years old and older without dementia at baseline residing in the community in the Seattle area and belonging to the Group Health Cooperative. Participants with 2 or more study visits were included, and those who had a hospitalization for a diagnosis of primary brain injury were censored at the time of hospitalization. Individuals were screened with the Cognitive Abilities Screening Instrument (CASI) (score range, 0-100) every 2 years at follow-up visits, and those with a score less than 86 underwent a clinical examination for dementia. MAIN OUTCOME MEASURES: Score on the CASI at follow-up study visits and incident dementia diagnosed in study participants, adjusted for baseline cognitive scores, age, and other risk factors. RESULTS: During a mean (SD) follow-up of 6.1 (3.2) years, 1601 participants had no hospitalization, 1287 had 1 or more noncritical illness hospitalizations, and 41 had 1 or more critical illness hospitalizations. The CASI score was assessed more than 45 days after discharge for 94.3% of participants. Adjusted CASI scores averaged 1.01 points lower for visits following acute care illness hospitalization compared with follow-up visits not following any hospitalization (95% confidence interval [CI], -1.33 to -0.70; P < .001) and 2.14 points lower on average for visits following critical illness hospitalization (95% CI, -4.24 to -0.03; P = .047). There were 146 cases of dementia among those not hospitalized, 228 cases of dementia among those with 1 or more noncritical illness hospitalizations, and 5 cases of dementia among those with 1 or more critical illness hospitalizations. The adjusted hazard ratio for incident dementia was 1.4 following a noncritical illness hospitalization (95% CI, 1.1 to 1.7; P = .001) and 2.3 following a critical illness hospitalization (95% CI, 0.9 to 5.7; P = .09). CONCLUSIONS: Among a cohort of older adults without dementia at baseline, those who experienced acute care hospitalization and critical illness hospitalization had a greater likelihood of cognitive decline compared with those who had no hospitalization. Noncritical illness hospitalization was significantly associated with the development of dementia.

RESUMO

Twenty percent of Americans die in an intensive care unit (ICU), often incapacitated or requiring assisted decision making. Surrogates are often required to make urgent, complex, high-stakes decisions. Communication among patients, families, and clinicians is often delayed and inefficient with frequent missed opportunities to support the emotional and psychological needs of surrogates, particularly at the end of life. The Critical Care Nurse Communicator program is a nurse-led, primary palliative care intervention designed to improve the quality and consistency of communication in the ICU and address the informational, psychological, and emotional needs of surrogate decision-makers through the shared decision-making process.

RESUMO

BACKGROUND: Dysphagia following extubation is common in intensive care unit (ICU) patients. Diagnosing postextubation dysphagia allows identification of patients who are at highest risk for aspiration and its associated adverse outcomes. Older adults are at an increased risk of postextubation dysphagia and its complications due to multiple comorbidities, a higher baseline risk of dysphagia, and increased risk of pneumonia. OBJECTIVES: We aimed to investigate the association between postextubation dysphagia and 1-year mortality in older patients. Secondary outcomes included ICU and hospital lengths of stay, ICU readmission, and place of discharge. METHODS: We performed a retrospective cohort study from January 1 to December 31, 2013. ICU patients, aged 65 years and older, who were successfully extubated and underwent a formal swallow evaluation by a speech and language pathologist (SLP) were included. Dysphagia was graded using a seven-point scale, and those with at least mild-moderate dysphagia were labeled as having clinically significant dysphagia. RESULTS: Of 1075 patients who were screened, 359 were survivors, aged 65 years and older; and of these survivors, 111 had a swallow evaluation performed by an SLP after liberation from mechanical ventilation. Mean age was 73.8 years (SD = 7.0 years), and 41.4% had clinically significant dysphagia. In a multivariable regression model, there was no significant association between dysphagia and 1-year mortality. Furthermore, there was no statistically significant difference in ICU or hospital length of stay, ICU readmission, or place of discharge of those with clinically significant dysphagia compared to those without. CONCLUSIONS: Among mechanically ventilated ICU patients, aged 65 years and older, who underwent a swallow evaluation following extubation, dysphagia was not associated with mortality, ICU and hospital lengths of stay, ICU readmission, and place of discharge. Given conflicting evidence in the literature, larger prospective studies are needed to clarify whether postextubation dysphagia is associated with worse outcomes in older patients admitted to the ICU.

RESUMO

BACKGROUND: Early mobility interventions in the intensive care unit can improve patients' outcomes, yet they are not routinely implemented in many intensive care units. In an effort to identify opportunities to implement and sustain evidence-based practice, prior work has demonstrated that understanding the decision-making process of health professionals is critical for identifying opportunities to improve program implementation. Nurses are often responsible for mobilizing patients, but how they overcome barriers and make decisions to mobilize patients in the intensive care unit is not understood. OBJECTIVE: To describe processes that nurses in intensive care units use to make decisions and barriers that influence their decision-making about patient mobility. METHODS: An exploratory descriptive approach using semi-structured interviews of a purposive sample of registered nurses in 2 intensive care units at 2 hospitals was used. Interviews were transcribed and analyzed by using directed content analysis to identify categories that describe nurses' decision-making about patient mobility. RESULTS: Semistructured interviews were conducted with 20 nurses in a 1-on-1 setting. Four main categories that influenced nurses' decision-making about mobility were identified in the directed content analysis: purpose of mobility, gathering information, establishing and activating the plan, and barriers to progressing the plan. CONCLUSIONS: Deciding to mobilize patients in the intensive care unit is a multifaceted, individualized decision made by nurses, and numerous patient-, nurse-, and unit-related factors influence that decision. Future studies that target unit culture and interprofessional perspectives are needed.

RESUMO

BACKGROUND: While most people living with HIV who are incarcerated in United States receive appropriate HIV care while they are in prison, interruptions in antiretroviral therapy and virologic failure are extremely common after they are released. The purpose of this study was to describe whether and how HIV stigma influences continuity of care for people living with HIV while they transition from prison to community settings. METHODS: We conducted semi-structured, telephone-based interviews with 32 adults who received HIV care while residing in a Wisconsin state prison, followed by a second interview 6 months after they returned to their home community. Interview transcripts were analyzed by an interdisciplinary research team using conventional content analysis. We identified themes based on commonly-reported experiences that were characterized as internalized stigma, perceived stigma, vicarious stigma, or enacted stigma. RESULTS: All four forms of HIV stigma appeared to negatively influence participants' engagement in community-based HIV care. Mechanisms described by participants included care avoidance due to concerns about HIV status disclosure and symptoms of depression and anxiety caused by internalized stigma. Supportive social relationships with clinic staff, professional case managers and supportive peers appeared to mitigate the impact of HIV stigma by increasing motivation for treatment adherence. CONCLUSIONS: HIV stigma is manifest in several different forms by people living with HIV who were recently incarcerated, and are perceived by patients to negatively influence their desire and ability to engage in HIV care. By being cognizant of the pervasive influence of HIV stigma on the lives of criminal justice involved adults, HIV care providers and clinical support staff can ameliorate important barriers to optimal HIV care for a vulnerable group of patients.
