Prevalence and severity of abscesses and cellulitis, and their associations with other health outcomes, in a community-based study of people who inject drugs in London, UK
Open accessAbstract
BACKGROUND: Skin and soft tissue infections (SSTI) are a common but preventable cause of morbidity and mortality among people who inject drugs (PWID). They can be severe, and hospitalisations of PWID with SSTI are rising. The most common SSTI presentations are abscesses and cellulitis. METHODS: We used data from Care & Prevent, a cross-sectional community survey of PWID in London. We reported the lifetime prevalence of SSTI, severity of infections, key risk factors, and associated sequelae. Pictorial questions were used to assess SSTI severity. RESULTS: We recruited 455 PWID. SSTI lifetime prevalence was high: 64% reported an abscess and/or cellulitis. Over one-third (37%) reported a severe infection, 137 (47%) reported hospitalisation. SSTIrisk factors were: aged 35+ years, injecting once or more times a day, subcutaneous or intra-muscular injections, and making four or more attempts to achieve an injection. Those who reported having other health conditions were at higher odds of having an abscess or cellulitis, with risk tending to increase with number of reported conditions. Half (46%) employed self-care for their worst SSTI, and 43% waited for ten or more days before seeking medical care or not seeking medical care at all. CONCLUSIONS: Abscess and cellulitis are very common among PWID in London. We corroborate findings indicating SSTIs are associated with risks, e.g. venous access problems, as well as other co-morbid conditions: septicaemia, endocarditis, DVT, and kidney disease. These co-morbidities may impact SSTIs severity and outcomes. Delayed healthcare seeking potentially exacerbates infection severity, which in turn increases poorer health outcomes and complications.

TL;DR
In a cross-sectional community survey of 455 people who inject drugs in London, lifetime prevalence of abscess and/or cellulitis was 64%, with 37% reporting a severe infection and 47% of those with bacterial SSTI reporting SSTI-related hospitalisation. SSTI was associated with older age, frequent injecting, non-venous injecting, repeated injection attempts, equipment reuse, more comorbidities, and delayed healthcare seeking.
Key findings
- Lifetime abscess and/or cellulitis prevalence was 64% (95% CI 60–68); 37% reported a severe infection, and among those with bacterial SSTI, 137/291 (47%) reported SSTI-related hospitalisation, rising to 79/107 (74%) among those with severe infection.
- Adjusted odds of lifetime bacterial SSTI were higher for age 35–44 (AOR 2.03, 95% CI 1.11–3.71) and 45+ (AOR 3.68, 2.09–6.50) versus <35; injecting once a day or more (AOR 1.61, 1.05–2.45); subcutaneous injecting (AOR 2.55, 1.49–4.35); intramuscular injecting (AOR 3.10, 1.74–5.52); and four or more attempts to achieve injection (AOR 5.01, 2.75–9.14).
- Comorbidity showed a graded association: compared with no diagnosed conditions, AORs rose from 2.01 (1.16–3.49) for one condition to 10.02 (2.67–37.57) for five or more; 48% (n=220) reported at least two diagnoses.
- Care delay was common: 60% (121) waited more than five days to seek medical advice, and 43% of those with severe infections waited 10 or more days or did not seek care; severe bacterial infection was associated with waiting 10+ days (AOR 2.29, 95% CI 1.25–4.20).
Methods
- Cross-sectional community survey (Care & Prevent) of PWID in London, recruited October 2017–March 2019 through six drug treatment services and a homeless outreach team; 455 participants completed the questionnaire.
- Eligibility: aged 18+ with a history of injecting psychoactive drugs; data came from a researcher-administered questionnaire using Open Data Kit, with pictorial questions showing mild/moderate/severe abscess and cellulitis to assess SSTI severity.
- Analysis used descriptive statistics, chi-square tests, and logistic regression adjusted for sex, age, and lifetime street homelessness; all variables were reported across participants’ injecting career unless stated otherwise.
Limitations
- Stated: the cross-sectional design cannot establish temporal relationships between SSTIs and injecting risk factors or report incidence; self-reported health conditions are susceptible to recall and awareness problems, such as misconstruing urinary tract infection as kidney disease.
- Stated: the validity of still images for self-reported SSTI severity is unknown; images were chosen with skin infection specialists but were not validated against a gold standard such as clinician evaluation, and clinical diagnosis was not possible.
- Evident: recruitment was opportunistic through treatment and outreach settings, and although the authors note comparability with the national UAM survey, the sample may not represent PWID outside these service-contact populations.

The paper relies on this without support.
Participants' self-reported lifetime history of SSTI and other health conditions is accurate enough to estimate prevalence and associations.
“Self-reported health conditions reported are susceptible to problems with recall and awareness of diseases, such as kidney disease, where participants may have been informed of a urinary tract infection but misconstrued this as kidney disease, and/or may not be aware if the disease is acute or chronic, particularly if they are not currently engaging with healthcare services.”
The paper relies on this without support.
The pictorial severity ratings correspond to clinically meaningful severity.
“The validity of the approach of still based images for self-report of SSTI severity is not known.”
“The images were chosen in consultation with skin infection specialists, but have not been validated or compared to a gold standard (such as clinician evaluation).”
The paper relies on this without support.
The temporal direction of the association between delayed care seeking and severe SSTI is that delay precedes and contributes to severity.
“The cross-sectional design meant that we were not able to establish a temporal relationship between bacterial SSTIs and these injecting risk factors, or report incidence.”
“Given these findings we posit that duration of time in seeking healthcare impacts severity of bacterial SSTI.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
