Evaluation of environmental contamination of Clostridium difficile associated diarrhea in hospital rooms at St. Luke's Episcopal Hospital (SLEH) and review of literature on environmental sampling

The study was carried out at St. Luke's Episcopal Hospital to evaluate environmental contamination of Clostridium difficile in the infected patient rooms. Samples were collected from the high risk areas and were immediately cultured for the presence of Clostridium difficile . Lack of microbial typing prevented the study of molecular characterization of the Clostridium difficile isolates obtained led to a change in the study hypothesis. The study found a positivity of 10% among 50 Hospital rooms sampled for the presence of Clostridium difficile. The study provided data that led to recommendations that routine environmental sampling be carried in the hospital rooms in which patients with CDAD are housed and that effective environmental disinfection methods are used. The study also recommended molecular typing methods to allow characterization of the CD strains isolated from patients and environmental sampling to determine their type, similarity and origin.^

A descriptive study on Hurricanes Katrina and Rita evacuees participating in the Harris County Housing Authority Disaster Housing Assistance Program

Natural disasters occur in various forms such as hurricanes, tsunamis, earthquakes, outbreaks, etc. The most unsettling aspect of a natural disaster is that it can strike at any moment. Over the past decade, our society has experienced an alarming increase of natural disasters. How to expeditiously respond and recover from natural disasters has become a precedent question for public health officials. To date, the most recent natural disaster was the January 12, 2010 earthquake in Haiti; however the most memorable was that of Hurricane Katrina (“Haiti Earthquake”, 2010). ^ This study provides insight on the need to develop a National Disaster Response and Recovery Program which effectively responds to natural disasters. The specific aims of this paper were to (1) observe the government’s role on federal, state and local levels in assisting Hurricanes Katrina and Rita evacuees, (2) assess the prevalence of needs among Hurricanes Katrina and Rita families participating in the Disaster Housing Assistance Program (DHAP) and (3) describe the level of progress towards “self sufficiency” for the DHAP families receiving case management social services. ^ Secondary data from a cross-sectional “Needs Assessment” questionnaire were analyzed. The questionnaire was administered initially and again six months later (follow-up) by H.A.U.L. case managers. The “Needs Assessment” questionnaire collected data regarding participants’ education, employment, transportation, child care, health resources, income, permanent housing and disability needs. Case managers determined the appropriate level of social services required for each family based on the data collected from the “Needs Assessment” questionnaire. ^ Secondary data provided by the H.A.U.L. were analyzed to determine the prevalence of needs among the DHAP families. In addition, differences measured between the initial and follow-up (at six months) questionnaires were analyzed to determine statistical significance between case management services provided and prevalence of needs among the DHAP families from initial to 6 months later at follow-up. The data analyzed describe the level of progress made by these families to achieve program “self sufficiency” (see Appendix A). Disaster assistance programs which first address basic human needs; then socioeconomic needs may offer an essential tool in aiding disaster affected communities quickly recover from natural disasters. ^

Epidemiological trends of influenza A positive patients hospitalized at St. Luke's Episcopal Hospital, Houston, Texas September, 2009--January, 2010

This study was a descriptive analysis of 437 influenza A positive inpatients and outpatients during the five month period between September, 2009 and January, 2010. The objective of the study was to describe the epidemiological trends of the total influenza A positive population and more specifically the clinical features of patients hospitalized with influenza A at St. Luke's Episcopal Hospital in Houston, Texas from September 2009 through January 2010. Eligible cases were included if they tested positive for influenza A test using the rapid antigen test and/or rRT-PCR. Hospitalized cases were included based on the laboratory confirmation of influenza A as well as hospital admission for at least 24 hours. Data was collected from medical record abstraction and included patient demographics, clinical history and history of chronic disease. Clinical findings in the differential diagnosis that led to laboratory-confirmation of influenza A as well as course of treatment during the hospital admission were summarized. Finally, co-morbid conditions charted during the hospital visit were reviewed and evaluated for associations with influenza A complications. During the study period, forty-eight patients were included in the study of which 27 tested positive for the H1N1 subtype. Females were more likely to be hospitalized than men. The median age of all patients admitted to St. Luke's Episcopal Hospital with influenza A was 42. The distribution for admitted cases was 15 White, 15 Black, and 18 Hispanic. Patients with co-morbid disease constituted 81% of the admissions for Influenza A. The presence of an underlying medical condition remains a risk factor for both seasonal and H1N1 influenza. Although respiratory conditions such as asthma and COPD are commonly associated with complications of seasonal influenza, patients with metabolic disorders such as kidney disease and/or diabetes were admitted more frequently (58%) during the study period. The patients in the study also of a much younger age than the age that is usually associated with complications of influenza infection, i.e. no patients greater than 65 years of age were admitted with a diagnosis of influenza A. Lower infection rates among elderly populations were similarly reported in other studies of influenza during the same time period. Older patient populations may benefit from antibodies to previous H1N1 strains that have circulated during the twentieth century, whereas younger age groups lack these exposures.^
