Controlling disease transmission in injection drug users

HIV seropositivity predicts longer duration of stay and rehospitalization among nonbacteremic febrile injection drug users with skin and soft tissue infections

BACKGROUND

Skin/soft tissue infections (SSTIs) are the leading cause of hospital admissions among injection drug users (IDUs).

METHODS

We performed a retrospective investigation to determine the epidemiology of SSTIs (ie, cellulitis and/or abscesses) in febrile IDUs, with a focus on bacteriology and potential predictors of increased health care utilization measured by longer length of stay and rehospitalization. Subjects were drawn from a cohort of febrile IDUs presenting to an inner-city emergency department from 1998 to 2004.

RESULTS

Of the 295 febrile IDUs with SSTIs, specific discharge diagnoses were cellulitis only (n = 143, 48.5%), abscesses only (n = 113, 38.3%), and both (n = 39, 13.2%). Documented HIV infection rate was 28%. Of note, 10 subjects were newly diagnosed with HIV infection during their visits. Staphylococcus aureus was the leading pathogen, and increasing rates of methicillin-resistant S. aureus emerged over time (before 2001: 4%, 2001-2004: 56%, P < 0.01). HIV seropositivity predicted rehospitalization within 90 days [adjusted hazard ratios and 95% confidence intervals: 2.90 (1.20 to 7.02)]. HIV seropositivity also predicted increased length of stay in those who were nonbacteremic [adjusted hazard ratios and 95% confidence intervals: 1.49 (1.11 to 2.01)].

CONCLUSIONS

Among febrile IDUs with SSTIs, a strong association between HIV seropositivity and health care resource utilization was found. Accordingly, attention to HIV serostatus should be considered in clinical disposition decisions for this vulnerable high-risk population.

Pharmacist support for selling syringes without a prescription to injection drug users in Rhode Island

OBJECTIVE

To examine pharmacists' attitudes and obstacles to syringe sales to IDUs without prescriptions in Rhode Island, around the time that such sales became legal in the state.

DESIGN

Self-administered written survey.

SETTING

Rhode Island.

PARTICIPANTS

400 randomly selected pharmacist members of the Rhode Island Pharmacists Association.

MAIN OUTCOME MEASURES

Responses to survey items.

RESULTS

Of the 400 pharmacists contacted, 131 (33%) completed and returned the survey; of these, 101 (77%) were pharmacists who worked in stores that provided direct nonprescription syringe sales to the public. The majority of these 101 pharmacists were willing to sell syringes to a suspected IDU without a prescription (65%), favored providing free sharps containers for disposal (68%), and supported providing pamphlets on safer injection practices (88%). Willingness to sell syringes to IDUs without a prescription was significantly correlated with various beliefs about possible consequences of sales.

CONCLUSION

The high level of support for nonprescription syringe sales to IDUs is promising. The correlation between the willingness to sell syringes to IDUs without a prescription and various beliefs suggests that future educational interventions might encourage pharmacists to sell syringes to this population without a prescription to decrease HIV and hepatitis transmission.
