Patterns and predictors of inpatient falls and fall-related injuries in a large academic hospital.

OBJECTIVES: Most research on hospital falls has focused on predictors of falling, whereas less is known about predictors of serious fall-related injury. Our objectives were to characterize inpatients who fall and to determine predictors of serious fall-related injury. METHODS: We performed a retrospective observational study of 1,082 patients who fell (1,235 falls) during January 2001 to June 2002 at an urban academic hospital. Multivariate analysis of potential risk factors for serious fall-related injury (vs no or minor injury) included in the hospital's adverse event reporting database was conducted with logistic regression to calculate adjusted odds ratios (aORs) with 95% confidence intervals (CI95) RESULTS: The median age of patients who fell was 62 years (interquartile range, 49-77 years), 50% were women, and 20% were confused. The hospital fall rate was 3.1 falls per 1,000 patient-days, which varied by service from 0.86 (women and infants) to 6.36 (oncology). Some (6.1%) of the falls resulted in serious injury, ranging by service from 3.1% (women and infants) to 10.9% (psychiatry). The most common serious fall-related injuries were bleeding or laceration (53.6%), fracture or dislocation (15.9%), and hematoma or contusion (13%). Patients 75 years or older (aOR, 3.2; CI95, 1.3-8.1) and those on the geriatric psychiatry floor (aOR, 2.8; CI95, 1.3-6.0) were more likely to sustain serious fall-related injuries. CONCLUSIONS: There is considerable variation in fall rates and fall-related injury percentages by service. More detailed studies should be conducted by floor or service to identify predictors of serious fall-related injury so that targeted interventions can be developed to reduce them.     

Epidemiology of methicillin-resistant Staphylococcus aureus colonization in a surgical intensive care unit.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is a cause of healthcare-associated infections among surgical intensive care unit (ICU) patients, though transmission dynamics are unclear. OBJECTIVE: To determine the prevalence of MRSA nasal colonization at ICU admission, to identify associated independent risk factors, to determine the value of these factors in active surveillance, and to determine the incidence of and risk factors associated with MRSA acquisition. DESIGN: Prospective cohort study. SETTING: Surgical ICU at a teaching hospital. PATIENTS: All patients admitted to the surgical ICU. RESULTS: Active surveillance for MRSA by nasal culture was performed at ICU admission during a 15-month period. Patients who stayed in the ICU for more than 48 hours had nasal cultures performed weekly and at discharge from the ICU, and clinical data were collected prospectively. Of 1,469 patients, 122 (8%) were colonized with MRSA at admission; 75 (61%) were identified by surveillance alone. Among 775 patients who stayed in the ICU for more than 48 hours, risk factors for MRSA colonization at admission included the following: hospital admission in the past year (1-2 admissions: adjusted odds ratio [aOR], 2.60 [95% confidence interval {CI}, 1.47-4.60]; more than 2 admissions: aOR, 3.56 [95% CI, 1.72-7.40]), a hospital stay of 5 days or more prior to ICU admission (aOR, 2.54 [95% CI, 1.49-4.32]), chronic obstructive pulmonary disease (aOR, 2.16 [95% CI, 1.17-3.96]), diabetes mellitus (aOR, 1.87 [95% CI, 1.10-3.19]), and isolation of MRSA in the past 6 months (aOR, 8.18 [95% CI, 3.38-19.79]). Sixty-nine (10%) of 670 initially MRSA-negative patients acquired MRSA in the ICU (corresponding to 10.7 cases per 1,000 ICU-days at risk). Risk factors for MRSA acquisition included tracheostomy in the ICU (aOR, 2.18 [95% CI, 1.13-4.20]); decubitus ulcer (aOR, 1.72 [95% CI, 0.97-3.06]), and receipt of enteral nutrition via nasoenteric tube (aOR, 3.73 [95% CI, 1.86-7.51]), percutaneous tube (aOR, 2.35 [95% CI, 0.74-7.49]), or both (aOR, 3.33 [95% CI, 1.13-9.77]). CONCLUSIONS: Active surveillance detected a sizable proportion of MRSA-colonized patients not identified by clinical culture. MRSA colonization on admission was associated with recent healthcare contact and underlying disease. Acquisition was associated with potentially modifiable processes of care.     

Pain, medication, and injury in older farmers

BACKGROUND: Agricultural work continues to be a dangerous occupation. Older farmers experience high risks for work-related injury. The purpose of this research was to determine if there is a relationship between medication use and injury among older male farmers in Alberta. METHODS: Using probabilistic linkage between an Alberta Agriculture government registry of farm operators and the Alberta Health Plan registry file, older farmers (aged 66 and older) were identified. Farm related injuries were identified using an E-code search of both hospitalization and emergency department separations for a 3-year period. Cases were matched to controls on age, geographic health region, and index injury date at a ratio of 1:5. Co-morbidity and medication use for each of the cases and controls were derived from population based health system utilization files. Conditional logistic regression was used to determine which medications were related to injury. RESULTS: Overall, a total of 282 farm related injuries were suffered by the linked group. Controlling for co-morbidity, farmers who had stopped taking narcotic pain killers (OR = 9.37 [95% CI:4.95, 17.72]) and non-steroidal anti-inflammatories (OR = 2.40 [95% CI:1.43, 4.03]) 30 days prior to the date of injury were at risk of injury. Those farmers taking sedatives up until the date of injury were also at risk (OR = 3.01 [95 CI:1.39, 6.52]). In addition, those suffering from incontinence/urinary tract disorders (OR = 2.95 [95% CI:1.30, 6.71]), and prior injury (OR = 1.42 [95% CI:1.04, 1.95]) were also at greater risk of injury. CONCLUSIONS: The relationship of medication use and injury in this population is different from those observed in studies of falls in older persons. We hypothesize that distraction from either pain or co-morbidity may play an important role in the etiology of injuries suffered in this active older working population. Further investigations in this area are required to confirm these findings.     

Risk factors for falls among Iowa farmers: a case-control study nested in the Agricultural Health Study

BACKGROUND: Farmers are at increased risk for fall-related injury compared with other occupations. Little is known about risk factors for non-fatal falls on the farm. This case-control study, nested within the Agricultural Health Study, aimed to assess risk factors for work-related falls among Iowa farmers. METHODS: A screener questionnaire sent to 6,999 farmers in 1998 identified 79 farmers who reported a fall-related farm injury that required medical advice or treatment in the previous year. Multivariable logistic regression analysis was used to assess several possible risk factors for injury among these farmers compared with 473 farmers with no injury in the previous year. RESULTS: There were significant associations between fall-related farm injury and age between 40 and 64 years (OR = 2.21; 95% CI = 1.20-4.07), doctor-diagnosed arthritis/rheumatism (OR = 2.05; 95% CI = 1.11-3.79), difficulty hearing normal conversation (even with a hearing aid, in the case of those who used one) (OR = 1.82; 95% CI = 1.07-3.08), and taking medications regularly (OR = 1.80; 95% CI = 1.02-3.18). CONCLUSIONS: Aging and health impairments, such as arthritis and hearing difficulties, are risk factors for which accommodations and preventive strategies can be devised to prevent fall-related injuries on the farm.     

Gender,socioeconomic, medical,and environmental factors related to domestic accidents of the elderly in Spain. Findings of a national survey

Domestic accidents pose serious threats to the independence of the elderly. We explored associations between domestic accidents and gender, socioeconomic, medical, and environmental factors using data from the European Health Survey 2014 for elderly Spanish female and male nationals. Records of 5960 participants (mean age ± SD: 75.9 ± 7.6 years), 59.8% of whom were women, were examined. Domestic accidents occurred in 460 (7.1%) seniors, predominately in women (78.5%). Age (adjusted odds ratio [aOR]: 1.02 [95% confidence interval [CI]: 1.00-1.03, p = .003], female gender (aOR 2.04 [95% CI 1.60-2.60, p < .001]), difficulty managing 12 stairs (reference: none) (some: aOR 2.03 [95% CI 1.53-2.68, p < .001]; much: aOR 2.88 [95% CI 2.15-3.87, p < .001]; inability: aOR 3.09 [95% CI 2.14-4.45, p < .001]), and depressive symptoms severity (reference: absent) (mild: aOR 1.44 [95% CI 1.10–1.89, p = .008]; moderate: aOR 1.91 [95% CI 1.35–2.71, p < .001];. Very severe: aOR 2.53 [95% CI 1.72-3.71, p < .001]; extremely severe: aOR 2.38 [95% CI 1.45-3.93, p = .001]) were independently associated with domestic accidents. Severity of depressive symptoms was the most prominent feature for women, while inability to manage 12 stairs was the most prominent for men. Our results suggest important gender differences in factors associated with domestic accidents that are relevant to intervention and preventive programs.     

Fatigue increases the risk of injury from sharp devices in medical trainees: results from a case-crossover study.

BACKGROUND: Extreme fatigue in medical trainees likely compromises patient safety, but regulations that limit trainee work hours have been controversial. It is not known whether extreme fatigue compromises trainee safety in the healthcare workplace, but evidence of such a relationship would inform the current debate on trainee work practices. Our objective was to evaluate the relationship between fatigue and workplace injury risk among medical trainees and nontrainee healthcare workers. DESIGN: Case-crossover study. SETTING: Five academic medical centers in the United States and Canada. PARTICIPANTS: Healthcare workers reporting to employee healthcare clinics for evaluation of needlestick injuries and other injuries related to sharp instruments and devices (sharps injuries). Consenting workers completed a structured interview about work patterns, time at risk of injury, and frequency of fatigue. RESULTS: Of 350 interviewed subjects, 109 (31%) were medical trainees. Trainees worked more hours per week (P<.001) and slept less the night before an injury (P<.001) than did other healthcare workers. Fatigue increased injury risk in the study population as a whole (incidence rate ratio [IRR], 1.40 [95% confidence interval {CI}, 1.03-1.90]), but this effect was limited to medical trainees (IRR, 2.94 [95% CI, 1.71-5.07]) and was absent for other healthcare workers (IRR, 0.97 [95% CI, 0.66-1.42]) (P=.001).Conclusions. Long work hours and sleep deprivation among medical trainees result in fatigue, which is associated with a 3-fold increase in the risk of sharps injury. Efforts to reduce trainee work hours may result in reduced risk of sharps-related injuries among this group.     

Moderate alcohol consumption during pregnancy and the risk of low birth weight and preterm birth. The generation R study

PURPOSE: To examine the associations of alcohol consumption in different periods of pregnancy with the risks of low birth weight and preterm birth. METHODS: This study was based on 7141 subjects participating in a population-based prospective cohort study from early pregnancy. Alcohol consumption was assessed in early, mid, and late pregnancy. Birth outcomes were birth weight in grams, low birth weight (<2500 g), small size for gestational age at birth (< -2 standard deviation scores) and preterm birth (gestational age <37 weeks). RESULTS: Overall, alcohol consumption during pregnancy was not associated with adverse birth outcomes. However, dose-response analyses showed tendencies toward adverse effects of average consumption of 1 or more alcoholic drinks per day in early pregnancy on birth weight (difference -129 g [95% confidence interval (CI): -271, 12]), low birth weight (adjusted odds ratio [aOR] 4.81 [95% CI: 1.10, 21.08]), small size for gestational age at birth (aOR 1.45 [95% CI: 0.33, 6.44]) and preterm birth (aOR 2.51 [95% CI: 0.92, 6.81]). Similar effects were found in late pregnancy. CONCLUSION: Average consumption of one or more but not less than one alcoholic drink per day in early or late pregnancy seems to be associated with adverse birth outcomes in the offspring.     

Bunk versus conventional beds: a comparative assessment of fall injury risk

OBJECTIVE: To depict the magnitude and spectrum of childhood injuries attributable to falls from bunk beds in comparison with conventional beds and to outline sociodemographic risk factors and injury characteristics. STUDY DESIGN: Case-control investigation. SETTING: Accident and emergency departments of four hospitals in Greece, namely a teaching children's hospital and a trauma hospital in Greater Athens and the two district hospitals in the Magnesia county and the Corfu island. PATIENTS: During the three year period 1996-98, 1881 children (0-14 years) presenting with bed fall injuries were recorded by the Emergency Department Injury Surveillance System (EDISS). Out of these, 197 children with falls from bunk beds served as cases and 1684 children with falls from conventional beds served as controls. RESULTS: From the analysis and a nationwide extrapolation, it was calculated that each year about 5000 children in Greece (total population 10 million) seek medical attendance at an emergency department for a bed injury, corresponding to an estimated incidence of about 3 per 1000 children years. Out of bed fall injuries, 10.5% are from bunk beds, 10.4% from cribs, 3.1% from cots, and 76.0% from other conventional beds. Falls from the bed ladder accounted for 8% of all bunk bed injuries. Boys are at higher risk for falls from beds but there is no evidence that the proportion is different depending on the type of bed used. Relatively few falls from bunk beds are recorded outside the crowded apartments of Greater Athens or among migrant children. The increased relative risk of injuries from bunk bed falls during the sleeping hours indicates the higher risk of injury after a fall from a bunk rather than a conventional bed. Injuries from bunk bed falls are generally more serious than those from conventional bed falls (overrepresentation of brain injuries, fractures, multiple injuries, and injuries requiring hospitalisation). Overall, it can be estimated that almost half of the sleep related bunk bed injuries are easily preventable. CONCLUSIONS: Falls from bunk beds represent a non-negligible childhood injury risk. A sizeable fraction can be avoided with simple design modifications of the product, such as use of side rails in the upper bed or removal of the bed ladder when not in use.     

Risk factors for death due to nosocomial infection in intensive care unit patients: findings from the Krankenhaus Infektions Surveillance System.

OBJECTIVE: To determine risk factors for death among patients with nosocomial pneumonia and patients with primary bloodstream infections (BSI) in intensive care units (ICUs). DESIGN: Prospective cohort study. SETTING: Data collected from January 1997 through June 2003 from ICUs registered with the Krankenhaus Infektions Surveillance System in Germany. PATIENTS: A total of 8,432 patients with nosocomial pneumonia from 202 ICUs and 2,759 patients with nosocomial primary BSI from 190 ICUs. METHODS: The following risk factors were considered in the analysis: age, sex, time in the ICU before onset of infection, type of ICU, type and size of hospital, intubation, central venous catheter use, total parenteral nutrition, and type of pathogen. RESULTS: A total of 750 patients (8.9%) with nosocomial pneumonia and 302 patients (10.9%) with nosocomial primary BSI died. Multiple logistic regression analysis identified treatment in a medical or surgical ICU (odds ratio [OR], 1.55 [95% confidence interval {CI}, 1.32-1.82]) or a hospital with more than 1,000 beds (OR, 2.14 [95% CI, 1.81-2.56]), age older than 65 years (OR, 1.54 [95% CI, 1.31-1.81]), and infection with methicillin-resistant Staphylococcus aureus (OR, 2.39 [95% CI, 1.81-3.12]) or multidrug-resistant Pseudomonas aeruginosa (OR, 3.00 [95% CI, 1.90-4.63]) as independent determinants of death from nosocomial pneumonia. Age older than the median of 63 years (OR, 1.44 [95% CI, 1.12-1.86]) and methicillin-resistant S. aureus as the causative agent (OR, 2.98 [95% CI, 1.81-5.82]) were both associated with increased mortality from primary BSI. The types of infecting pathogens, particularly those resistant to multiple drugs, were also strong outcome predictors among ICU patients. CONCLUSIONS: The study results underline the need for further investigations of the role of antimicrobial resistance in the outcome of patients with nosocomial pneumonia and patients with primary BSI.     

Effect of Preexisting Musculoskeletal Diseases on the 1-Year Incidence of Fall-related Injuries

Objectives

People who have chronic diseases, as well as gait imbalance or psychiatric drug use, may be susceptible to injuries from falls and slips. The purpose of this study was to evaluate the effect of musculoskeletal diseases on incidental fall-related injuries among adults in Korea.

Methods

We analyzed data from the 4th Korea National Health and Nutrition Examination Survey (2007-2009), which are national data obtained by a rolling survey sampling method. The 1-year incidence of fall-related injuries was defined by health service utilization within the last year due to injury occurring after a slip and fall, and musculoskeletal diseases included osteoarthritis, rheumatoid arthritis, osteoporosis, and back pain. To evaluate the effects of preexisting musculoskeletal diseases, adults diagnosed before the last year were considered the exposed group, and adults who had never been diagnosed were the unexposed group.

Results

The weighted lifetime prevalence of musculoskeletal disease was 32 540 per 100 000 persons. Musculoskeletal diseases were associated with a higher risk of fall-related injury after adjustment for sex, age, residence, household income, education, occupation, visual disturbance, paralysis due to stroke, and medication for depression (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.03 to 1.93). As the number of comorbid musculoskeletal diseases increased, the risk of fall-induced injuries increased (p-value for trend <0.001). In particular, patients who had any musculoskeletal condition were at much higher risk of recurrent fall-related injuries (OR, 6.20; 95% CI, 1.06 to 36.08).

Conclusions

One must take into account the risk of fall-related injuries and provide prevention strategies among adults who have musculoskeletal diseases.     

Risk factors for and impact of infection or colonization with aztreonam-resistant Pseudomonas aeruginosa.

OBJECTIVE: To identify risk factors for infection or colonization with aztreonam-resistant Pseudomonas aeruginosa and examine the impact of this organism on mortality. DESIGN: A case-control study was performed to identify risk factors for infection or colonization with aztreonam-resistant P. aeruginosa. A cohort study was subsequently performed to examine the impact of aztreonam resistance on outcomes. SETTING: A tertiary referral center in southeastern Pennsylvania.Participants. Inpatients with a clinical culture positive for P. aeruginosa between January 1, 1999, and December 31, 2000. RESULTS: Of 720 P. aeruginosa. isolates, 183 (25.4%) were aztreonam-resistant and 537 (74.6%) were aztreonam susceptible. In a multivariable model, prior fluoroquinolone use (adjusted odds ratio [aOR], 1.81 [95% confidence interval {CI}, 1.17-2.80]), prior use of an antianaerobic agent (aOR, 1.56 [95% CI, 1.06-2.29]), and renal insufficiency (aOR, 1.59 [95% CI, 1.10-2.29]) were associated with infection or colonization with aztreonam-resistant P. aeruginosa, while older age (aOR, 0.98 [95% CI, 0.97-0.99] per year of age) was negatively associated with infection or colonization with this organism. In-hospital mortality was higher among subjects infected or colonized with aztreonam-resistant P. aeruginosa, compared with those who were infected or colonized with aztreonam-susceptible P. aeruginosa (25.7% vs 16.8%; P=.009), but in multivariable analysis, no significant association was found between infection or colonization with aztreonam-resistant P. aeruginosa and mortality. CONCLUSIONS: Curbing the use of fluoroquinolones and antimicrobials with antianaerobic activity may be an effective strategy to limit the emergence of aztreonam-resistant P. aeruginosa.     

Fall-related occupational injuries on farms

We assessed risk factors for fall-related farm injuries in a population-based, case-control study. Cases had to reside in a defined geographic region served by a single medical center. Multiple sources reported cases, and a special farm census enabled random selection of controls. The annual risk of farm fall injury was 7.5 (95% CI: 5.7, 10.0) per 1,000 person-years. The crude incidence rate was higher in men, while the rate based on hours of farmwork was higher in women. In a multivariate analysis of risk factors, three factors were significantly associated with the risk. The risk of fall injury increased 2% (95% CI: 1%, 4%) per hour worked. Residents of farms with some farm workers not living on the farm had a fall injury rate 2.5 (95% CI: 1.0, 6.2) times greater than residents of other farms. Residents of farms with registered cows had one-third (95% CI: 0.14, 0.93) the risk of residents of other farms. To identify environmental hazards for fall injuries, researchers from several disciplines may need to collaborate in the design and conduct of studies that include injury site investigations. © 1996 Wiley-Liss, Inc.     

Prevalence of SARS-CoV-2 Antibodies in First Responders and Public Safety Personnel,New York City,New York,USA, May–July 2020

We conducted a serologic survey in public service agencies in New York City, New York, USA, during May–July 2020 to determine prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among first responders. Of 22,647 participants, 22.5% tested positive for SARS-CoV-2–specific antibodies. Seroprevalence for police and firefighters was similar to overall seroprevalence; seroprevalence was highest in correctional staff (39.2%) and emergency medical technicians (38.3%) and lowest in laboratory technicians (10.1%) and medicolegal death investigators (10.8%). Adjusted analyses demonstrated association between seropositivity and exposure to SARS-CoV-2–positive household members (adjusted odds ratio [aOR] 3.52 [95% CI 3.19–3.87]), non-Hispanic Black race or ethnicity (aOR 1.50 [95% CI 1.33–1.68]), and severe obesity (aOR 1.31 [95% CI 1.05–1.65]). Consistent glove use (aOR 1.19 [95% CI 1.06–1.33]) increased likelihood of seropositivity; use of other personal protective equipment had no association. Infection control measures, including vaccination, should be prioritized for frontline workers.     

Risk factors for surgical site infection after low transverse cesarean section.

BACKGROUND: Independent risk factors for surgical site infection (SSI) after cesarean section have not been well documented, despite the large number of cesarean sections performed and the relatively common occurrence of SSI. OBJECTIVE: To determine independent risk factors for SSI after low transverse cesarean section. DESIGN: Retrospective case-control study. SETTING: Barnes-Jewish Hospital, a 1,250-bed tertiary care hospital. PATIENTS: A total of 1,605 women who underwent low transverse cesarean section during the period from July 1999 to June 2001. METHODS: Using the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes for SSI or wound complication and/or data on antibiotic use during the surgical hospitalization or at readmission to the hospital or emergency department, we identified potential cases of SSI in a cohort of patients who underwent a low transverse cesarean section. Cases of SSI were verified by chart review using the definitions from the Centers for Disease Control and Prevention's National Nosocomial Infections Surveillance System. Control patients without SSI or endomyometritis were randomly selected from the population of patients who underwent cesarean section. Independent risk factors for SSI were determined by logistic regression. RESULTS: SSIs were identified in 81 (5.0%) of 1,605 women who underwent low transverse cesarean section. Independent risk factors for SSI included development of subcutaneous hematoma after the procedure (adjusted odds ratio [aOR], 11.6 [95% confidence interval [CI], 4.1-33.2]), operation performed by the university teaching service (aOR, 2.7 [95% CI, 1.4-5.2]), and a higher body mass index at admission (aOR, 1.1 [95% CI, 1.0-1.1]). Cephalosporin therapy before or after the operation was associated with a significantly lower risk of SSI (aOR, 0.2 [95% CI, 0.1-0.5]). Use of staples for skin closure was associated with a marginally increased risk of SSI. CONCLUSIONS: These independent risk factors should be incorporated into approaches for the prevention and surveillance of SSI after surgery.

Association of executive function impairment, history of falls and physical performance in older adults: A cross-sectional population-based study in Eastern France

Objective

To estimate: 1) the association between executive function (EF) impairment and falls; and 2) the association of EF impairment on tests of physical function used in the evaluation of fall risk.

Design

Cross-sectional study.

Setting

Thirteen health examination centres in Eastern France.

Participants

Four thousand four hundred and eighty one community-dwelling older adults without dementia aged 65 to 97 years (mean age 71.8±5.4, women 47.6%).

Measurements

Participants underwent a comprehensive medical assessment that included evaluations of EF using the Clock Drawing Test and of physical performance using the Timed Up & Go Test (TUG). Analysis used multivariable modified Poisson regression to evaluate the association between impaired EF and each of the fall outcomes (any fall, recurrent falls, fall-related injuries). Multivariable linear regression was used to evaluate the association between EF impairment and performance on the TUG and grip strength.

Results

EF impairment, assessed using the clock drawing test, was present in 24.9% of participants. EF impairment was independently associated with an increased risk of any fall (RR=1.13, 95% CI (1.03, 1.25)) and major soft tissue fall-related injury (RR= 2.42, 95% CI (1.47, 4.00)). Additionally, EF impairment was associated with worse performance on the TUG (p<0.0001).

Conclusions

EF impairment among older adults without dementia was highly prevalent and was independently associated with an increased risk for falls, fall-related injuries and with decreased physical function. The use of the Clock Drawing Test is an easy to administer measure of EF that can be used routinely in comprehensive fall risk evaluations.     

Baseline indicators for measuring progress in preventing falls injury in older people

Objective: Over recent years, there has been increasing attention given to preventing falls and falls injury in older people through policy and other initiatives. This paper presents a baseline set of fall injury outcome indicators against which these preventive efforts can be assessed in terms of monitoring the rate of fall-related deaths and hospitalisations.
Methods: ICD-10-AM coded hospital separations, Australian Bureau of Statistics (ABS) mortality and ABS population data were used to determine the rate of fall-related injury mortality and hospitalisations occurring in people aged 65+ years in New South Wales (NSW), Australia, over the six-year period from 1998/99 to 2003/04, inclusive.
Results: Baseline trends for one fatality and five separations-based metrics are presented. Overall, fall mortality rates increased over the six years, with higher rates in males. Falls hospitalisation rates also increased slightly, with higher rates in females. The rates of hip fracture and pelvic fracture hospital separations generally declined over the six years and were highest in females. The level of unspecified and missing information about the place where falls occur increased by 1.5%.
Conclusion: Baseline trends in fall injury outcome metrics highlight the severity and frequency of fall injuries before wide scale implementation of the Management Policy to Reduce Fall Injury Among Older People in NSW.
Implications: Future use of these metrics will help to evaluate and monitor the progress of falls prevention in older people in NSW. They could also be adopted in other jurisdictions.     

Outbreak of Salmonella javiana infection at a children's hospital.

OBJECTIVE: To determine the source of an outbreak of Salmonella javiana infection. DESIGN: Case-control study. PARTICIPANTS: A total of 101 culture-confirmed cases and 540 epidemiologically linked cases were detected between May 26, 2003, and June 16, 2003, in hospital employees, patients, and visitors. Asymptomatic employees who had eaten in the hospital cafeteria between May 30 and June 4, 2003, and had had no gastroenteritis symptoms after May 1, 2003, were chosen as control subjects. SETTING: A 235-bed academic tertiary care children's hospital. RESULTS: Isolates from 100 of 101 culture-confirmed cases had identical pulsed-field gel electrophoresis patterns. A foodhandler with symptoms of gastroenteritis was the presumed index subject. In multivariate analysis, case subjects were more likely than control subjects to have consumed items from the salad bar (adjusted odds ratio [aOR], 5.3; 95% confidence interval [CI], 2.3-12.1) and to have eaten in the cafeteria on May 28 (aOR, 9.4; 95% CI, 1.8-49.5), May 30 (aOR, 3.6; 95% CI, 1.0-12.7), and/or June 3 (aOR, 4.0; 95% CI, 1.4-11.3). CONCLUSIONS: Foodhandlers who worked while they had symptoms of gastroenteritis likely contributed to the propagation of the outbreak. This large outbreak was rapidly controlled through the use of an incident command center.     

Needlestick injuries among nurses of Fars province, Iran

PURPOSE: A prevalence survey was performed to estimate the magnitude and predictors for needlestick injury (NSI) in nurses of Fars province hospitals. METHODS: Questionnaires were distributed in 52 hospitals to a stratified random sample of 2,118 (46.3%) nurses between April and September 2005 to collect self-reported NSI in the past 12- months. RESULTS: Of the 1,555 nurses who returned a completed questionnaire, 49.6% (95% confidence interval [95 CI] 47.1%-52.1%) recalled at least one sharps injury, of which 52.6% were classified as NSI. Just over one fourth (26.3%; 95 CI 24.1%-28.6%, 409/1,555) of respondents sustained at least one NSI, 75.6% (95 CI 71.1%-79.6%) recalled having sustained between 1 and 4 injuries in the past 12-months, of which 72.2% involved a hollow-bore needle and 95.1% of injuries involved fingers. Predictors of NSI included being a registered nurse (odds ratio [OR] 1.6, 95% CI 1.1-2.3) or midwife (OR 2.4, 95% CI 1.4-3.9) compared with nurse managers, being employed in a hospital located in other cities smaller than Shiraz (OR 1.4, 95% CI 1.1-1.8). Nurses who reported a previous contaminated NSI were less likely to sustain a further injury (OR 0.3, 95% CI 0.2-0.4). CONCLUSION: The prevalence of NSI in Iranian nurses is high, with the majority of injured staff having sustained up to 4 NSIs in a 12-month period. Nearly all NSIs were high-risk injuries involving a hollow-bore needle. Providing nursing staff with safety-engineered devices, including retractable syringes when hollow-bore needles are to be used, will be an important step toward reducing our NSI epidemic.
