Is inadequate human immunodeficiency virus care associated with increased ED and hospital utilization? A prospective study in human immunodeficiency virus-positive ED patients

All-cause hospitalization according to demographic group in people living with HIV in the current antiretroviral therapy era

OBJECTIVE

We investigated differences in all-cause hospitalization between key demographic groups among people with HIV in the UK in the current antiretroviral therapy (ART) era.

DESIGN/METHODS

We used data from the Royal Free HIV Cohort study between 2007 and 2018. Individuals were classified into five groups: MSM, Black African men who have sex with women (MSW), MSW of other ethnicity, Black African women and women of other ethnicity. We studied hospitalizations during the first year after HIV diagnosis (Analysis-A) separately from those more than one year after diagnosis (Analysis-B). In Analysis-A, time to first hospitalization was assessed using Cox regression adjusted for age and diagnosis date. In Analysis-B, subsequent hospitalization rate was assessed using Poisson regression, accounting for repeated hospitalization within individuals, adjusted for age, calendar year, time since diagnosis.

RESULTS

The hospitalization rate was 30.7/100 person-years in the first year after diagnosis and 2.7/100 person-years subsequently; 52% and 13% hospitalizations, respectively, were AIDS-related. Compared with MSM, MSW and women were at much higher risk of hospitalization during the first year [aHR (95% confidence interval, 95% CI): 2.7 (1.7-4.3), 3.0 (2.0-4.4), 2.0 (1.3-2.9), 3.0 (2.0-4.5) for Black African MSW; other ethnicity MSW; Black African women; other ethnicity women respectively, Analysis-A] and remained at increased risk subsequently [corresponding aIRR (95% CI): 1.7 (1.2-2.4), 2.1 (1.5-2.8), 1.5 (1.1-1.9), 1.7 (1.2-2.3), Analysis-B].

CONCLUSION

In this setting with universal healthcare, substantial variation exists in hospitalization risk across demographic groups, both in early and subsequent periods after HIV diagnosis, highlighting the need for targeted interventions.

Prospective association of social circumstance, socioeconomic, lifestyle and mental health factors with subsequent hospitalisation over 6-7 year follow up in people living with HIV

BACKGROUND

Predictors of hospitalisation in people with HIV (PLHIV) in the contemporary treatment era are not well understood.

METHODS

This ASTRA sub-study used clinic data linkage and record review to determine occurrence of hospitalisations among 798 PLHIV from baseline questionnaire (February to December 2011) until 1 June 2018. Associations of baseline social circumstance, socioeconomic, lifestyle, mental health, demographic and clinical factors with repeated all-cause hospitalisation from longitudinal data were investigated using Prentice-Williams-Peterson models. Associations were also assessed in 461 individuals on antiretroviral therapy (ART) with viral load ≤50 copies/ml and CD4 count ≥500 cells/ µl.

FINDINGS

Rate of hospitalisation was 5.8/100 person-years (95% CI: 5.1-6.5). Adjusted for age, demographic group and time with diagnosed HIV, the following social circumstance, socioeconomic, lifestyle and mental health factors predicted hospitalisation: no stable partner (adjusted hazard ratio (aHR)=1.59; 95% CI=1.16-2.20 vs living with partner); having children (aHR=1.50; 1.08-2.10); non-employment (aHR=1.56; 1.07-2.27 for unemployment; aHR=2.39; 1.70-3.37 for sick/disabled vs employed); rented housing (aHR=1.72; 1.26-2.37 vs homeowner); not enough money for basic needs (aHR=1.82; 1.19-2.78 vs enough); current smoking (aHR=1.39; 1.02-1.91 vs never); recent injection-drug use (aHR=2.11; 1.30-3.43); anxiety symptoms (aHRs=1.39; 1.01-1.91, 2.06; 1.43-2.95 for mild and moderate vs none/minimal); depressive symptoms (aHRs=1.67; 1.17-2.38, 1.91; 1.30-2.78 for moderate and severe vs none/minimal); treated/untreated depression (aHRs=1.65; 1.03-2.64 for treated depression only, 1.87; 1.39-2.52 for depressive symptoms only; 1.53; 1.05-2.24; for treated depression and depressive symptoms, versus neither). Associations were broadly similar in those with controlled HIV and high CD4.

INTERPRETATION

Social circumstance, socioeconomic disadvantage, adverse lifestyle factors and poorer mental health are strong predictors of hospitalisation in PLHIV, highlighting the need for targeted interventions and care.

Resource utilization across the continuum of HIV care: An emergency department-based cohort study

BACKGROUND

The objective of this study was to determine the healthcare resource utilization for people living with HIV (PLWH) presenting to the emergency department (ED) across the HIV Care Continuum.

METHODS

This prospective study enrolled PLWH presenting to an urban ED between June 2016 and March 2017. Subjects were categorized as being linked to care, retained in care, on antiretroviral therapy (ART), and virally suppressed (<200 copies/ml). Data on ED visit rates, duration of stay, and hospital admission rates were compared to local metrics.

RESULTS

Overall, 94.3% of 159 enrollees had been linked to care, 75.5% retained in care, 81.1% on ART, and 62.8% virally suppressed. Compared to the general population of the city and of the ED, participants had a higher ED visit rate (3.0 v. 1.2 visits per person-per year) in the past two years, a higher median duration of ED stay (12.6 v. 7.6 h), and a higher hospital admission rate (36.5% v. 24.9%) during their index ED visit. Viral suppression was negatively associated with admission (OR = 0.35, 95% CI: 0.17, 0.72). Forty-eight (30.2%) participants who had at least eight ED visits in the past two years were more likely to have a diagnosed mental health disorder (79.2% v. 62.2%, p=0.036).

CONCLUSIONS

Our results showed that PLWH use more ED resources than the general population and a better engagement in HIV care is linked to lesser ED resource utilization for PLWH, indicating the importance of improved HIV care engagement in healthcare utilization 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.

HIV Care Continuum for HIV-Infected Emergency Department Patients in an Inner-City Academic Emergency Department

STUDY OBJECTIVE

The recently released HIV Care Continuum Initiative is a cornerstone of the National AIDS Strategy and a model for improving care for those living with HIV. To our knowledge, there are no studies exploring the entirety of the HIV Care Continuum for patients in the emergency department (ED). We determine gaps in the HIV Care Continuum to identify potential opportunities for improved care for HIV-infected ED patients.

METHODS

A mixed-methods approach was used in 1 inner-city ED in 2007. Data elements were derived from an identity-unlinked HIV seroprevalence study, an ongoing nontargeted HIV screening program, and a structured survey of known HIV-positive ED patients.

RESULTS

Identity-unlinked testing of 3,417 unique ED patients found that 265 (7.8%) were HIV positive. Of patients testing HIV positive, 73% had received a previous diagnosis (based on self-report, chart review, or presence of antiretrovirals in serum), but only 61% were recognized by the clinician as being HIV infected (based on self-report or chart review). Of patients testing positive, 43% were linked to care, 39% were retained in care, 27% were receiving antiretrovirals, 26% were aware of their receiving antiretroviral treatment, 22% were virally suppressed, and only 9% were self-aware of their viral suppression.

CONCLUSION

To our knowledge, this study is the first to quantify gaps in HIV care for an ED patient population, with the HIV Care Continuum as a framework. Our findings identified distinct phases (ie, testing, provider awareness of HIV diagnosis, and linkage to care) in which the greatest opportunities for intervention exist, if appropriate resources were allocated. This schema could serve as a model for other indolent treatable diseases frequently observed in EDs, where continuity of care is critical.

Changes in the etiology, incidence and prognosis of acute lower respiratory track infections in human immunodeficiency virus patients

AIM

To describe the incidence, the changes in the etiology and the prognosis of lower respiratory tract infection (LRTI) in HIV infected patients, presenting by the first time to the Emergency Department (ED), during years 2000-2010.

STUDY DESIGN

Prospective collection of data.

METHODS

Data were collected on the first visit of HIV-infected patients at our ED due to a LRTI, (defined according to the criteria of the European Respiratory Society), between 1/1/2000 and 31/12/2010. A series of epidemiological and laboratory variables as well as the need for admission to the intensive care unit (ICU). LRTI etiology were also collected. The influence ofthe mentioned variables on 30-day mortality were analyzed.

RESULTS

One hundred thirty one patients were included. LRTI represented 27% of visits to the ED by HIV-infected patients. Mean age was 39±9 years. 72% of patients were males. 18% required admission to the ICU. The most frequent LRTI was pneumonia by P. jiroveci in 35 cases, bacterial penumonia in 27 and pulmonary tuberculosis in 20. LRTI incidence gradually reduced significantly over time from 6.13 × 1000 patients/year in year 2000 to 0.23 × 1000 patients/year in 2010 (p<0.05). Overall mortality was 14%. Logistic regression analysis showed that admission to ICU (p<0.004) and viral load (p<0.029) were independent variables predicting mortality.

CONCLUSION

LRTI is a pathology with a decreasing incidence, probably related to the widespread utilization increased of HAART regimens. lts etiology has also been changing, but with a non negligible mortality, mostly when ICU admission was required.
