Organizational characteristics of local health departments and environmental health services and activities
Banerjee SN , Gerding JA , Sarisky J . J Environ Health 2018 80 (8) 20-29 The main objective of this research was to ascertain the association between organizational characteristics of local health departments (LHDs) and environmental health (EH) services rendered in the community. Data used for the analysis were collected from LHDs by the National Association of County and City Health Officials for its 2013 national profile study of LHDs. We analyzed the data during 2016. Apart from understanding basic characteristics of LHDs in the nation, we introduced new measures of these characteristics, including "EH full-time equivalents" per 100,000 population and "other revenue" (revenues from fees and fines) per capita. The association of these and other organizational characteristics with EH services were measured using likelihood ratio §² and t-tests. Out of 34 EH services considered, LHDs directly provided an average of 12 different services. As many as 41% of the 34 EH services were not available in more than 10% of the communities served by LHDs. About 70% of communities received some services from organizations other than LHDs. All the available organizational characteristics of LHDs had association with some of the EH services. Although we might assume an increase in per capita expenditure could result in an increase in LHDs' direct involvement in providing EH services, we found it to be true only for five (15%) of the EH services. The variation of EH services provided in communities could be explained by a combination of factors such as fee generation, community needs, type of governance, and population size. |
Acute gastroenteritis on cruise ships - United States, 2008-2014
Freeland AL , Vaughan GH Jr , Banerjee SN . MMWR Morb Mortal Wkly Rep 2016 65 (1) 1-5 From 1990 to 2004, the reported rates of diarrheal disease (three or more loose stools or a greater than normal frequency in a 24-hour period) on cruise ships decreased 2.4%, from 29.2 cases per 100,000 travel days to 28.5 cases (1,2). Increased rates of acute gastroenteritis illness (diarrhea or vomiting that is associated with loose stools, bloody stools, abdominal cramps, headache, muscle aches, or fever) occurred in years that novel strains of norovirus, the most common etiologic agent in cruise ship outbreaks, emerged (3). To determine recent rates of acute gastroenteritis on cruise ships, CDC analyzed combined data for the period 2008-2014 that were submitted by cruise ships sailing in U.S. jurisdiction (defined as passenger vessels carrying ≥13 passengers and within 15 days of arriving in the United States) (4). CDC also reviewed laboratory data to ascertain the causes of acute gastroenteritis outbreaks and examined trends over time. During the study period, the rates of acute gastroenteritis per 100,000 travel days decreased among passengers from 27.2 cases in 2008 to 22.3 in 2014. Rates for crew members remained essentially unchanged (21.3 cases in 2008 and 21.6 in 2014). However, the rate of acute gastroenteritis was significantly higher in 2012 than in 2011 or 2013 for both passengers and crew members, likely related to the emergence of a novel strain of norovirus, GII.4 Sydney (5). During 2008-2014, a total of 133 cruise ship acute gastroenteritis outbreaks were reported, 95 (71%) of which had specimens available for testing. Among these, 92 (97%) were caused by norovirus, and among 80 norovirus specimens for which a genotype was identified, 59 (73.8%) were GII.4 strains. Cruise ship travelers experiencing diarrhea or vomiting should report to the ship medical center promptly so that symptoms can be assessed, proper treatment provided, and control measures implemented. |
Walking associated with public transit: moving toward increased physical activity in the United States
Freeland AL , Banerjee SN , Dannenberg AL , Wendel AM . Am J Public Health 2013 103 (3) 536-42 OBJECTIVES: We assessed changes in transit-associated walking in the United States from 2001 to 2009 and documented their importance to public health. METHODS: We examined transit walk times using the National Household Travel Survey, a telephone survey administered by the US Department of Transportation to examine travel behavior in the United States. RESULTS: People are more likely to transit walk if they are from lower income households, are non-White, and live in large urban areas with access to rail systems. Transit walkers in large urban areas with a rail system were 72% more likely to transit walk 30 minutes or more per day than were those without a rail system. From 2001 to 2009, the estimated number of transit walkers rose from 7.5 million to 9.6 million (a 28% increase); those whose transit-associated walking time was 30 minutes or more increased from approximately 2.6 million to 3.4 million (a 31% increase). CONCLUSIONS: Transit walking contributes to meeting physical activity recommendations. Study results may contribute to transportation-related health impact assessment studies evaluating the impact of proposed transit systems on physical activity, potentially influencing transportation planning decisions.

Comparison of Etest method with reference broth microdilution method for antimicrobial susceptibility testing of Yersinia pestis
Lonsway DR , Urich SK , Heine HS , McAllister SK , Banerjee SN , Schriefer ME , Patel JB . J Clin Microbiol 2011 49 (5) 1956-60 Utility of Etest for antimicrobial susceptibility testing of Yersinia pestis was evaluated in comparison with broth microdilution and disk diffusion for eight agents. Four laboratories tested 26 diverse strains and found Etest to be reliable for testing antimicrobial agents used to treat Y. pestis, except for chloramphenicol and trimethoprim-sulfamethoxazole. Disk diffusion testing is not recommended. |
Catheter-related polymicrobial bloodstream infections among pediatric bone marrow transplant outpatients-Atlanta, Georgia, 2007
Wiersma P , Schillie S , Keyserling H , Watson JR , De A , Banerjee SN , Drenzek CL , Arnold KE , Shivers C , Kendrick L , Ryan LG , Jensen B , Noble-Wang J , Srinivasan A . Infect Control Hosp Epidemiol 2010 31 (5) 522-7 OBJECTIVE: To identify risk factors for polymicrobial bloodstream infections (BSIs) in pediatric bone marrow transplant (BMT) outpatients attending a newly constructed clinic affiliated with a children's hospital. METHODS: All 30 outpatients treated at a new BMT clinic during September 10-21, 2007, were enrolled in a cohort study. The investigation included interviews, medical records review, observations, and bacterial culture and molecular typing of patient and environmental isolates. Data were analyzed using exact conditional logistic regression. RESULTS: Thirteen patients experienced BSIs caused by 16 different, predominantly gram-negative organisms. Presence of a tunneled catheter (odds ratio [OR], 19.9 [95% confidence interval {CI}, 2.4-infinity), catheter access (OR, 13.7 [95% CI, 1.8-infinity]), and flushing of a catheter with predrawn saline (OR, 12.9 [95% CI, 1.0-766.0]) were independently associated with BSI. The odds of experiencing a BSI increased by a factor of 16.8 with each additional injection of predrawn saline (95% CI, 1.8-827.0). Although no environmental source of pathogens was identified, interviews revealed breaches in recommended infection prevention practice and medication handling. Saline flush solutions were predrawn, and multiple doses were obtained from single-dose preservative-free vials to avoid delays in patient care. CONCLUSION: We speculate that infection prevention challenges in the new clinic, combined with successive needle punctures of vials, facilitated extrinsic contamination and transmission of healthcare-associated pathogens. We recommend that preservative-free single-use vials not be punctured more than once. Use of single-use prefilled saline syringes might prevent multiuse of single-use saline vials. Storage of saline outside a medication supply system might be advisable. Before opening new clinic facilities, hospitals should consider conducting a mock patient flow exercise to identify infection control challenges. |
Administrative coding data and health care-associated infections
Jhung MA , Banerjee SN . Clin Infect Dis 2009 49 (6) 949-55 Surveillance for health care-associated infections (HAIs) using administrative data has received attention from health care epidemiologists searching for efficient means to track infections in their institutions. Several states are also considering electronic surveillance that incorporates administrative data as a means to satisfy an increasing demand for mandatory public reporting of HAIs. International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) discharge diagnosis codes have attributes that make them suitable for detecting HAIs; for example, they may facilitate automated surveillance, freeing up infection control personnel to perform other important tasks, such as staff education and outbreak investigation. However, controversy surrounds the appropriate use of ICD-9-CM data in detecting HAIs, and administrative coding data have been criticized for lacking elements necessary for surveillance. Administrative coding data are inappropriate as the sole means of HAI surveillance but may have value to the health care epidemiologist as a way to augment traditional methods. |
