Trends in discharges from the HIV/AIDS ward at a tertiary Canadian Hospital from 2005 to 2014

Infectious diseases, comorbidities and outcomes in hospitalized people who inject drugs (PWID)

Injection drug use poses a public health challenge. Clinical experience indicates that people who inject drugs (PWID) are hospitalized frequently for infectious diseases, but little is known about outcomes when admitted. Charts were identified from local hospitals between 2013-2018 using consultation lists and hospital record searches. Included individuals injected drugs in the past six months and presented with infection. Charts were accessed using the hospital information system, undergoing primary and secondary reviews using Research Electronic Data Capture (REDCap). The Wilcoxon rank-sum test was used for comparisons between outcome categories. Categorical data were summarized as count and frequency, and compared using Fisher's exact test. Of 240 individuals, 33% were admitted to the intensive care unit, 36% underwent surgery, 12% left against medical advice (AMA), and 9% died. Infectious diagnoses included bacteremia (31%), abscess (29%), endocarditis (29%), cellulitis (20%), sepsis (10%), osteomyelitis (9%), septic arthritis (8%), pneumonia (7%), discitis (2%), meningitis/encephalitis (2%), or other (7%). Sixty-six percent had stable housing and 60% had a family physician. Fifty-four percent of patient-initiated discharges were seen in the emergency department within 30 days and 29% were readmitted. PWID are at risk for infections. Understanding their healthcare trajectory is essential to improve their care.

"With a PICC line, you never miss": The role of peripherally inserted central catheters in hospital care for people living with HIV/HCV who use drugs

BACKGROUND

People who use drugs (PWUD), and especially those who inject drugs, are at increased risk of acquiring bloodborne infections (e.g., HIV and HCV), experiencing drug-related harms (e.g., abscesses and overdose), and being hospitalized and requiring inpatient parenteral antibiotic therapy delivered through a peripherally inserted central catheter (PICC). The use of PICC lines with PWUD is understood to be a source of tension in hospital settings but has not been well researched. Drawing on theoretical and analytic insights from "new materialism," we consider the assemblage of sociomaterial elements that inform the use of PICCs.

METHODS

This paper draws on n = 50 interviews conducted across two related qualitative research projects within a program of research about the impact of substance use on hospital admissions from the perspective of healthcare providers (HCPs) and people living with HIV/HCV who use drugs. This paper focuses on data about PICC lines collected in both studies.

RESULTS

The decision to provide, maintain, or remove a PICC is based on a complex assemblage of factors (e.g., infections, bodies, drugs, memories, relations, spaces, temporalities, and contingencies) beyond whether parenteral intravenous antibiotic therapy is clinically indicated. HCPs expressed concerns about the risk posed by past, current, and future drug use, and contact with non-clinical spaces (e.g., patient's homes and the surrounding community), with some opting for second-line treatments and removing PICCs. The majority of PWUD described being subjected to threats of discharge and increased monitoring despite being too ill to use their PICC lines during past hospital admissions. A subset of PWUD reported using their PICC lines to inject drugs as a harm reduction strategy, and a subset of HCPs reported providing harm reduction-centred care.

CONCLUSION

Our analysis has implications for theorizing the role of PICC lines in the care of PWUD and identifies practical guidance for engaging them in productive and non-judgemental discussions about the risks of injecting into a PICC line, how to do it safely, and about medically supported alternatives.

Health programmes and services addressing the prevention and management of infectious diseases in people who inject drugs in Canada: a systematic integrative review

OBJECTIVES

People who inject drugs (PWID) experience a high burden of injection drug use-related infectious disease and challenges in accessing adequate care. This study sought to identify programmes and services in Canada addressing the prevention and management of infectious disease in PWID.

DESIGN

This study employed a systematic integrative review methodology. Electronic databases (PubMed, CINAHL and Web of Science Core Collection) and relevant websites were searched for literature published between 2008 and 2019 (last search date was 6 June 2019). Eligible articles and documents were required to address injection or intravenous drug use and health programmes or services relating to the prevention or management of infectious diseases in Canada.

RESULTS

This study identified 1607 unique articles and 97 were included in this study. The health programmes and services identified included testing and management of HIV and hepatitis C virus (n=27), supervised injection facilities (n=19), medication treatment for opioid use disorder (n=12), integrated infectious disease and addiction programmes (n=10), needle exchange programmes (n=9), harm reduction strategies broadly (n=6), mobile care initiatives (n=5), peer-delivered services (n=3), management of IDU-related bacterial infections (n=2) and others (n=4). Key implications for policy, practice and future research were identified based on the results of the included studies, which include addressing individual and systemic factors that impede care, furthering evaluation of programmes and the need to provide comprehensive care to PWID, involving medical care, social support and harm reduction.

CONCLUSIONS

These results demonstrate the need for expanded services across a variety of settings and populations. Our study emphasises the importance of addressing social and structural factors that impede infectious disease care for PWID. Further research is needed to improve evaluation of health programmes and services and contextual factors surrounding accessing services or returning to care.

Outcomes and complications of hospitalised patients with HIV-TB co-infection

BACKGROUND

Tuberculosis is one of the most common causes of hospitalisation in patients with HIV. Despite this, hospital outcomes of patients with this co-infection have rarely been described since antiretroviral therapy became widely available.

METHODS

Prospective cohort study of HIV-infected adult patients hospitalised with TB in six referral hospitals in Medellin, Colombia, from August 2014 to July 2015.

RESULTS

Among 128 HIV-infected patients hospitalised with tuberculosis, the mean age was 38.4 years; 79.7% were men. HIV was diagnosed on admission in 28.9% of patients. The median CD4 + T-cell count was 125 (±158 SD) cells/µL. Only 47.3% of patients with a known diagnosis of HIV upon admission were on antiretroviral therapy, and only 11.1% had a tuberculin skin test in the previous year. Drug toxicity due to tuberculosis medications occurred in 11.7% of patients. Mean length of stay was 23.2 days, and 10.7% of patients were readmitted. Mortality was 5.5%.

CONCLUSIONS

Hospital mortality attributable to tuberculosis in patients with HIV is low in reference hospitals in Colombia. Cases of tuberculosis in HIV-infected patients occur mainly in patients with advanced HIV, or not on antiretroviral therapy, despite a known diagnosis of HIV. Only one of every 10 patients in this cohort had active screening for latent tuberculosis, possibly reflecting missed treatment opportunities.

Hospitalization Rates and Causes Among Persons With HIV in the United States and Canada, 2005-2015

BACKGROUND

To assess the possible impact of antiretroviral therapy improvements, aging, and comorbidities, we examined trends in all-cause and cause-specific hospitalization rates among persons with HIV (PWH) from 2005 to 2015.

METHODS

In 6 clinical cohorts, we followed PWH in care (≥1 outpatient CD4 count or HIV load [VL] every 12 months) and categorized ICD codes of primary discharge diagnoses using modified Clinical Classifications Software. Poisson regression estimated hospitalization rate ratios for calendar time trends, adjusted for demographics, HIV risk factor, and annually updated age, CD4, and VL.

RESULTS

Among 28 057 patients (125 724 person-years), from 2005 to 2015, the median CD4 increased from 389 to 580 cells/µL and virologic suppression from 55% to 85% of patients. Unadjusted all-cause hospitalization rates decreased from 22.3 per 100 person-years in 2005 (95% confidence interval [CI], 20.6-24.1) to 13.0 in 2015 (95% CI, 12.2-14.0). Unadjusted rates decreased for almost all diagnostic categories. Adjusted rates decreased for all-cause, cardiovascular, and AIDS-defining conditions, increased for non-AIDS-defining infection, and were stable for most other categories.

CONCLUSIONS

Among PWH with increasing CD4 counts and viral suppression, unadjusted hospitalization rates decreased for all-cause and most cause-specific hospitalizations, despite the potential effects of aging, comorbidities, and cumulative exposure to HIV and antiretrovirals.
