Relationship of HIV care engagement to emergency department utilization

Measuring Health Equity in Emergency Care Using Routinely Collected Data: A Systematic Review

Introduction: Achieving equity in health care remains a challenge for health care systems worldwide and marked inequities in access and quality of care persist. Identifying health care equity indicators is an important first step in integrating the concept of equity into assessments of health care system performance, particularly in emergency care.

Methods: We conducted a systematic review of administrative data-derived health care equity indicators and their association with socioeconomic determinants of health (SEDH) in emergency care settings. Following PRISMA-Equity reporting guidelines, Ovid MEDLINE, EMBASE, PubMed, and Web of Science were searched for relevant studies. The outcomes of interest were indicators of health care equity and the associated SEDH they examine.

Results: Among 29 studies identified, 14 equity indicators were identified and grouped into four categories that reflect the patient emergency care pathway. Total emergency department (ED) visits and ambulatory care-sensitive condition-related ED visits were the two most frequently used equity indicators. The studies analyzed equity based on seven SEDH: social deprivation, income, education level, social class, insurance coverage, health literacy, and financial and nonfinancial barriers. Despite some conflicting results, all identified SEDH are associated with inequalities in access to and use of emergency care.

Conclusion: The use of administrative data-derived indicators in combination with identified SEDH could improve the measurement of health care equity in emergency care settings across health care systems worldwide. Using a combination of indicators is likely to lead to a more comprehensive, well-rounded measurement of health care equity than using any one indicator in isolation. Although studies analyzed focused on emergency care settings, it seems possible to extrapolate these indicators to measure equity in other areas of the health care system. Further studies elucidating root causes of health inequities in and outside the health care system are needed.

Care of Sexual and Gender Minorities in the Emergency Department: A Scoping Review

STUDY OBJECTIVE

This scoping review was conducted to collate and summarize the published research literature addressing sexual and gender minority care in the emergency department (ED).

METHODS

Using PRISMA-ScR criteria, an electronic search was conducted of CINAHL, Embase, Ovid Medline, and Web of Science for all studies that were published after 1995 involving sexual and gender minorities, throughout all life stages, presenting to an ED. We excluded non-US and Canadian studies and editorials. Titles and abstracts were screened, and full-text review was performed independently with 4 reviewers. Abstraction focused on study design, demographics, and outcomes, and the resulting data were analyzed using an ad hoc iterative thematic analysis.

RESULTS

We found 972 unique articles and excluded 743 after title and abstract screening. The remaining 229 articles underwent full-text review, and 160 articles were included. Themes identified were HIV in sexual and gender minorities (n=61), population health (n=46), provider training (n=29), ED avoidance or barriers (n=23), ED use (n=21), and sexual orientation/gender identity information collection (n=9).

CONCLUSION

The current literature encompassing ED sexual and gender minority care cluster into 6 themes. There are considerable gaps to be addressed in optimizing culturally competent and equitable care in the ED for this population. Future research to address these gaps should include substantial patient stakeholder engagement in all aspects of the research process to ensure patient-focused outcomes congruent with sexual and gender minority values and preferences.

Evaluation of an Emergency Department and Hospital-Based Data Exchange to Improve HIV Care Engagement and Viral Suppression

BACKGROUND

Emergency department (ED) visits and inpatient (IP) admissions may provide an opportunity to reengage poorly engaged people living with HIV and facilitate viral suppression. In 2015, Public Health Seattle and King County partnered with the University of Washington Medicine to implement a real-time data exchange to identify virally unsuppressed people living with HIV seen at the ED/IP hospital and reengage them in HIV care. We evaluated the impact of the data exchange on care engagement and viral suppression.

METHODS

Public Health Seattle and King County received a text alert on weekdays 8 AM to 6 PM for ED/IP patients previously diagnosed with HIV with a most recent viral load ≥200 copies/mL. We compared viral load testing <3 months and viral suppression <6 months after an alert-eligible visit in the 2 years after intervention and the 7 to 30 months before intervention. To account for secular trends, we used difference-in-differences models to compare patients with alert-window visits to patients with visits outside the alert window before and after intervention.

RESULTS

Patients with visits within the alert window in the postintervention period were 1.08 (95% confidence interval [CI], 0.97-1.20) times more likely to have a viral load test within 3 months after an ED visit/IP admission and 1.50 (95% CI, 1.27-1.76) times more likely to achieve viral suppression within 6 months than patients in the preintervention period. However, care engagement (difference-in-differences relative risk, 1.00; 95% CI, 0.84-1.18) and viral suppression (difference-in-differences relative risk, 1.01; 95% CI, 0.84-1.20) trends were similar among patients with visits outside the alert window.

CONCLUSIONS

Real-time data exchange with ED/IP hospitals was associated with improved viral suppression, but not increased care engagement. However, our results may reflect secular trends resulting from diverse interventions, of which ours was only one. More efforts are needed to improve the effectiveness of relinkage interventions guided by real-time data exchange.

Methamphetamine use drives decreases in viral suppression for people living with HIV released from a large municipal jail: Results of the LINK LA clinical trial

BACKGROUND

People living with HIV (PLWH) often experience decreases in HIV viral suppression (VS) after release from jail. The Linking Inmates to Care in LA (LINK LA) peer navigation intervention helped maintain VS 12 months after release from jail compared to standard of care. In this study, we analyzed correlates of substance use and tested whether substance use was an independent correlate of decreased VS in LINK LA participants.

METHODS

We analyzed LINK LA data collected at baseline, 3, and 12 months. We defined high-risk drug use as any reported methamphetamine, cocaine, or opioid use in the 30 days prior to a study visit (or jail entry at baseline). We used generalized linear mixed models to test associations of sociodemographic variables with type of substance used, and we tested correlates of VS while controlling for time, the intervention, and their interaction.

RESULTS

At baseline (n = 356), 71% of participants reported high-risk drug use: 58%, methamphetamine; 17%, cocaine; 7%, heroin; and 4%, prescription opioids. Non-Hispanic Whites and those younger than 35 were most likely to use methamphetamine; Blacks were most likely to use cocaine; people who inject drugs were most likely to use opioids. Participants who used high-risk drugs had 53% lower adjusted odds than non-users of maintaining VS (AOR 0.47, 95% CI 0.31-0.70, p < 0.001).

CONCLUSION

High-risk drug use, dominated by methamphetamine use, independently correlated with decreased VS among recently incarcerated PLWH. Improving HIV care continuum outcomes among populations leaving jail requires attention to efforts to address high-risk drug use.

Association between Federally Qualified Health Center usage and emergency department utilization among California's HIV-infected Medicaid beneficiaries, 2009

Federally Qualified Health Centers (FQHCs) have long been important sources of care for publicly insured people living with HIV. FQHC users have historically used emergency departments (EDs) at a higher-than-average rate. This paper examines whether this greater use relates to access difficulties in FQHCs or to characteristics of FQHC users. Zero-inflated Poisson models were used to estimate how FQHC use related to the odds of being an ED user and annual number of ED visits, using claims data on 6,284 HIV-infected California Medicaid beneficiaries in 2008-2009. FQHC users averaged significantly greater numbers of annual ED visits than non-FQHC users and those with no outpatient usage (1.89, 1.59, and 1.70, respectively; P = 0.043). FQHC users had higher odds of being ED users (OR = 1.14; 95%CI 1.02-1.27). In multivariable analyses, FQHC clients had higher odds of ED usage controlling for demographic and service characteristics (OR = 1.15; 95%CI 1.02-1.30) but not when medical characteristics were included (OR = 1.08; 95%CI 0.95-1.24). Among ED users, FQHC use was not significantly associated with the number of ED visits in our models (rate ratio (RR) = 1.00; 95%CI 0.87-1.15). The overall difference in mean annual ED visits observed between FQHC and non-FQHC groups was reduced to insignificance (1.75; 95% CI 1.59-1.92 vs 1.70; 95%CI 1.54-1.85) after adjusting for demographic, service, and medical characteristics. Overall, FQHC users had higher ED utilization than non-FQHC users, but the disparity was largely driven by differences in underlying medical characteristics.

Emergency department arrival times in Florida heart failure patients utilizing Fisher-Rao curve registration: A descriptive population-based study

BACKGROUND

Emergency room utilization and hospital readmission rates are disproportionately high for heart failure patients (HF). Emergency department (ED) utilization is intimately intertwined with hospital readmissions.

OBJECTIVE

Describe the arrival time distribution of HF patients presenting to the ED.

METHOD

The study analyzed heart failure discharge data from the Florida State Emergency Department Database and the Florida State Inpatient Database from the Healthcare Cost and Utilization Project of the Agency for Healthcare Research and Quality. Data were treated as a Poisson process and analyzed using functional data analysis tools.

RESULTS

HF arrivals are multi-modal with the largest peak arrival time in the middle of the day as well as a smaller peak in the early morning hours, especially in rural areas.

CONCLUSIONS

The arrival pattern has minor differences in rural and urban areas. HF clinic appointments should be established in the early morning hours when these patients utilize the ED.

Hospitalization Rates Among People With HIV/AIDS in New York City, 2013

Background

Hospitalizations are an important indicator of healthcare quality and access for people with human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). This study assesses hospitalization rates among people with HIV/AIDS in New York City.

Methods

We performed a deterministic match between people in the New York City HIV surveillance registry alive as of 1 January 2013 and diagnosed with HIV as of 31 December 2013 and patient-level inpatient hospitalization records during 2013. Event-level data were analyzed to determine characteristics of and reasons for hospitalizations. Primary diagnoses were classified using the International Classification of Diseases, Ninth Revision, Clinical Modification. We estimated hospitalization rates as the number of hospitalizations per 100 person-years for all causes, AIDS-defining illnesses, and non-AIDS-defining infections.

Results

Nearly one-fifth of hospitalizations were attributed to non-AIDS-defining infections, whereas AIDS-defining illness diagnoses were infrequent (3.6% of hospitalizations). Other common causes were cardiovascular (10.9%) and substance use (9.8%). The estimated all-cause hospitalization rate was 36.7 per 100 person-years. Higher all-cause hospitalization rates were observed among females (46.8 per 100 person-years), Black and Latino/Hispanic people (41.8 and 39.5 per 100 person-years, respectively), people living in high-poverty neighborhoods (47.4 per 100 person-years), and people with a history of injection drug use (74.9 per 100 person-years). The estimated AIDS-defining illness and non-AIDS-defining infection hospitalization rates were 1.3 and 7.2 per 100 person-years, respectively.

Conclusions

People with HIV in New York City were frequently hospitalized. While AIDS-defining illnesses were relatively rare, non-AIDS-defining infection hospitalizations were more common. Disparities in hospitalization rates indicate a need for targeted improved primary care and comorbid disease management.

Trends and Comparisons of Utilization of Emergency Departments Due to Traumatic or Non-Traumatic Causes among the HIV-Positive Population in Taiwan, 2006-2011

It is important that the utilization of emergency departments (EDs) among people living with the human immunodeficiency virus (HIV) be epidemiologically evaluated in order to assess and improve the HIV care continuum. All participants newly-diagnosed with HIV in Taiwan registered in the National Health Insurance Database from 2000 to 2005 were enrolled in this study and followed-up from 2006 to 2011. In total, 3500 participants newly-diagnosed with HIV in 2000–2005 were selected as a fixed-cohort population and followed-up from 2006 to 2011. Overall, 704, 645, 591, 573, 578, and 568 cases made 1322, 1275, 1050, 1061, 1136, and 992 ED visits in 2006, 2007, 2008, 2009, 2010 and 2011, respectively, with an average number of ED visits ranging from 1.75 to 1.98 per person, accounting for 20.1–22.6% of the whole HIV-positive population. Fewer ED visits were due to traumatic reasons, accounting for 19.6–24.4% of all cases. The incidence of traumatic and non-traumatic ED visits among the HIV-positive participants ranged from 7.2–9.3 and 27.0–33.9 per 100 people, respectively. The average direct medical cost of traumatic and non-traumatic ED visits ranged from $89.3–112.0 and $96.6–120.0, respectively. In conclusion, a lower incidence of ED visits for all reasons and fewer ED visits owing to traumatic causes were observed in the population living with HIV in comparison with the general population; however, the direct medical cost of each ED visit owing to both traumatic and non-traumatic causes was greater among those living with HIV than in the general population.

Emergency department use by people with HIV in Ontario: a population-based cohort study

BACKGROUND

Emergency department use may reflect poor access to primary care. Our objective was to compare rates and causes of emergency department use between adults living with and without HIV.

METHODS

We conducted a population-based study involving Ontario residents living with and without HIV between Apr. 1, 2011, and Mar. 31, 2012. We frequency matched adults with HIV to 4 HIV-negative people by age, sex and census division, and used random-effects negative binomial regression to compare rates of emergency department use. We classified visits as low urgency or high urgency, and also examined visits for ambulatory care sensitive conditions. Hospital admission following an emergency department visit was a secondary outcome.

RESULTS

We identified 14 534 people with HIV and 58 136 HIV-negative individuals. Rates of emergency department use were higher among people with HIV (67.3 v. 31.2 visits per 100 person-years; adjusted rate ratio 1.58, 95% confidence interval [CI] 1.51-1.65). Similar results were observed for low-urgency visits. With the exception of hypertension, visit rates for ambulatory care sensitive conditions were higher among people with HIV. People with HIV were also more likely than HIV-negative individuals to be admitted to hospital following an emergency department visit (adjusted odds ratio 1.55, 95% CI 1.43-1.69).

INTERPRETATION

Compared with HIV-negative individuals, people with HIV had high rates of emergency department use, including potentially avoidable visits. These findings strongly support the need for comprehensive care for people with HIV.
