A Retrospective Study of Clinical Encounters for Pelvic Inflammatory Disease: Missed Opportunities to Screen for Syphilis and HIV?

OBJECTIVE: Missed screening opportunities may contribute to the rising rates of sexually transmitted and blood borne infections (STBBIs) in Manitoba. This study sought to determine the proportion of women who are screened for syphilis and human immunodeficiency virus (HIV) when admitted with pelvic inflammatory disease (PID). METHODS: We performed a retrospective analysis of all inpatient admissions for PID over 3 discrete years (fiscal years 2007, 2012, 2017) at a single tertiary care centre. Data extracted from medical records included STBBI screening performed, clinical signs at presentation, and history of PID or STBBI. To improve the accuracy of our estimates, we complemented the records data with population data from Manitoba. We evaluated predictive factors influencing any or concurrent STBBI screening using bivariate analysis for significance (P < 0.05). RESULTS: One hundred and five admissions met inclusion criteria. Syphilis and HIV screening was ordered concurrently with chlamydia and gonorrhoea screening in 6 (6%) of encounters and was ordered at any point during admission for PID in 28 (27%). A history of substance abuse (odds ratio [OR] 4.94 [95% CI 1.62-15.05] for syphilis screening and OR 6.94 [95% CI 2.38-20.23] for HIV screening) and a positive gonorrhea result while admitted (OR 3.40 [95% CI 1.06-10.88] for syphilis screening) were strongly associated with receiving any screening. Reporting multiple sexual partners was also strongly associated with receiving any STBBI screening while admitted (OR 19.44 [95% CI 2.01-187.92] and OR 15.00 [95% CI 1.58-142.70] for syphilis and HIV screening, respectively). CONCLUSION: A minority of patients were screened for syphilis and HIV while admitted for PID. This study highlights a missed opportunity to screen for STBBI among sexually active women.

Pandemic (H1N1) 2009 influenza in hospitalized children in Manitoba: nosocomial transmission and lessons learned from the first wave.

OBJECTIVE: To review the experiences at Winnipeg Children's Hospital (WCH) during the 2009 influenza season, with an emphasis on nosocomial transmission and infection prevention and control responses. DESIGN: A case series of patients admitted to WCH who had laboratory-confirmed cases of influenza between January 1 and July 31, 2009, with a comparison of patients with seasonal influenza and those with pandemic (H1N1) 2009 influenza; a review of the impact of infection prevention and control modifications on nosocomial transmission. PATIENTS AND SETTING: A total of 104 inpatients with influenza, 81 of whom had pandemic (H1N1) 2009 influenza, were reviewed at a large Canadian pediatric tertiary care center. RESULTS: There were no differences in risk factors, presentation, or outcome between patients with seasonal influenza and those with pandemic (H1N1) 2009 influenza. There were 8 nosocomial cases of pandemic (H1N1) 2009 influenza. Excluding patients with nosocomial cases, mean length of hospital stay was significantly shortened to 3.7 days for individuals who had pandemic (H1N1) 2009 influenza and who received empiric oseltamivir on admission to the hospital, compared with 12.0 days for patients for whom treatment was delayed (P = .02). Treatment with oseltamivir of all patients with suspected cases of influenza and prompt modifications to infection control practices, including playroom closures and enhanced education of visitors and staff, terminated nosocomial transmission. CONCLUSIONS: Infection with pandemic (H1N1) 2009 influenza virus resulted in a substantial number of hospitalizations of pediatric patients in Manitoba, including those with nosocomial cases, thereby stressing the capacity of WCH. Immediate therapy with oseltamivir on admission to the hospital resulted in a significantly reduced length of hospitalization. This, coupled with intensified infection prevention and control practices, halted nosocomial transmission. These strategies should be considered in future pandemic influenza or other respiratory viral outbreaks.
