BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is an emerging cause of infections outside of health care settings. We investigated an outbreak of abscesses due to MRSA among members of a professional football team and examined the transmission and microbiologic characteristics of the outbreak strain. METHODS: We conducted a retrospective cohort study and nasal-swab survey of 84 St. Louis Rams football players and staff members. S. aureus recovered from wound, nasal, and environmental cultures was analyzed by means of pulsed-field gel electrophoresis (PFGE) and typing for resistance and toxin genes. MRSA from the team was compared with other community isolates and hospital isolates. RESULTS: During the 2003 football season, eight MRSA infections occurred among 5 of the 58 Rams players (9 percent); all of the infections developed at turf-abrasion sites. MRSA infection was significantly associated with the lineman or linebacker position and a higher body-mass index. No MRSA was found in nasal or environmental samples; however, methicillin-susceptible S. aureus was recovered from whirlpools and taping gel and from 35 of the 84 nasal swabs from players and staff members (42 percent). MRSA from a competing football team and from other community clusters and sporadic cases had PFGE patterns that were indistinguishable from those of the Rams' MRSA; all carried the gene for Panton-Valentine leukocidin and the gene complex for staphylococcal-cassette-chromosome mec type IVa resistance (clone USA300-0114). CONCLUSIONS: We describe a highly conserved, community-associated MRSA clone that caused abscesses among professional football players and that was indistinguishable from isolates from various other regions of the United States.

IMPORTANCE: Financial penalties for readmission have been expanded beyond medical conditions to include surgical procedures. Hospitals are working to reduce readmissions; however, little is known about the reasons for surgical readmission. OBJECTIVE: To characterize the reasons, timing, and factors associated with unplanned postoperative readmissions. DESIGN, SETTING, AND PARTICIPANTS: Patients undergoing surgery at one of 346 continuously enrolled US hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) between January 1, 2012, and December 31, 2012, had clinically abstracted information examined. Readmission rates and reasons (ascertained by clinical data abstractors at each hospital) were assessed for all surgical procedures and for 6 representative operations: bariatric procedures, colectomy or proctectomy, hysterectomy, total hip or knee arthroplasty, ventral hernia repair, and lower extremity vascular bypass. MAIN OUTCOMES AND MEASURES: Unplanned 30-day readmission and reason for readmission. RESULTS: The unplanned readmission rate for the 498,875 operations was 5.7%. For the individual procedures, the readmission rate ranged from 3.8% for hysterectomy to 14.9% for lower extremity vascular bypass. The most common reason for unplanned readmission was surgical site infection (SSI) overall (19.5%) and also after colectomy or proctectomy (25.8%), ventral hernia repair (26.5%), hysterectomy (28.8%), arthroplasty (18.8%), and lower extremity vascular bypass (36.4%). Obstruction or ileus was the most common reason for readmission after bariatric surgery (24.5%) and the second most common reason overall (10.3%), after colectomy or proctectomy (18.1%), ventral hernia repair (16.7%), and hysterectomy (13.4%). Only 2.3% of patients were readmitted for the same complication they had experienced during their index hospitalization. Only 3.3% of patients readmitted for SSIs had experienced an SSI during their index hospitalization. There was no time pattern for readmission, and early (≤7 days postdischarge) and late (>7 days postdischarge) readmissions were associated with the same 3 most common reasons: SSI, ileus or obstruction, and bleeding. Patient comorbidities, index surgical admission complications, non-home discharge (hazard ratio [HR], 1.40 [95% CI, 1.35-1.46]), teaching hospital status (HR, 1.14 [95% CI 1.07-1.21]), and higher surgical volume (HR, 1.15 [95% CI, 1.07-1.25]) were associated with a higher risk of hospital readmission. CONCLUSIONS AND RELEVANCE: Readmissions after surgery were associated with new postdischarge complications related to the procedure and not exacerbation of prior index hospitalization complications, suggesting that readmissions after surgery are a measure of postdischarge complications. These data should be considered when developing quality indicators and any policies penalizing hospitals for surgical readmission.

OBJECTIVE: To determine the attributable cost of ventilator-associated pneumonia from a hospital-based cost perspective, after adjusting for potential confounders. DESIGN: Patients admitted between January 19, 1998, and December 31, 1999, were followed prospectively for the occurrence of ventilator-associated pneumonia. Hospital costs were defined by using the hospital cost accounting database. SETTING: The medical and surgical intensive care units at a suburban, tertiary care hospital. PATIENTS: Patients requiring >24 hrs of mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We measured occurrence of ventilator-associated pneumonia, in-hospital mortality rate, total intensive care unit (ICU) and hospital lengths of stay (LOS), and total hospital cost per patient. Ventilator-associated pneumonia occurred in 127 of 819 patients (15.5%). Compared with uninfected, ventilated patients, patients with ventilator-associated pneumonia had a higher Acute Physiology and Chronic Health Evaluation II score on admission (p <.001) and were more likely to require multiple intubations (p <.001), hemodialysis (p <.001), tracheostomy (p <.001), central venous catheters (p <.001), and corticosteroids (p <.001). Patients with ventilator-associated pneumonia were more likely to be bacteremic during their ICU stay (36 [28%] vs. 22 [3%]; p <.001). Patients with ventilator-associated pneumonia had significantly higher unadjusted ICU LOS (26 vs. 4 days; p <.001), hospital LOS (38 vs. 13 days; p <.001), mortality rate (64 [50%] vs. 237 [34%]; p <.001), and hospital costs (70,568 dollars vs. 21,620 dollars, p <.001). Multiple linear regression, controlling for other factors that may affect costs, estimated the attributable cost of ventilator-associated pneumonia to be 11,897 dollars (95% confidence interval = 5,265 dollars-26,214 dollars; p <.001). CONCLUSIONS: Patients with ventilator-associated pneumonia had significantly longer ICU and hospital LOS, with higher crude hospital cost and mortality rate compared with uninfected patients. After we adjusted for underlying severity of illness, the attributable cost of ventilator-associated pneumonia was approximately 11,897 dollars.

BACKGROUND: Delayed treatment of candidemia has previously been shown to be an important determinant of patient outcome. However, septic shock attributed to Candida infection and its determinants of outcome have not been previously evaluated in a large patient population. METHODS: A retrospective cohort study of hospitalized patients with septic shock and blood cultures positive for Candida species was conducted at Barnes-Jewish Hospital, a 1250-bed urban teaching hospital (January 2002-December 2010). RESULTS: Two hundred twenty-four consecutive patients with septic shock and a positive blood culture for Candida species were identified. Death during hospitalization occurred among 155 (63.5%) patients. The hospital mortality rate for patients having adequate source control and antifungal therapy administered within 24 hours of the onset of shock was 52.8% (n = 142), compared to a mortality rate of 97.6% (n = 82) in patients who did not have these goals attained (P < .001). Multivariate logistic regression analysis demonstrated that delayed antifungal treatment (adjusted odds ratio [AOR], 33.75; 95% confidence interval [CI], 9.65-118.04; P = .005) and failure to achieve timely source control (AOR, 77.40; 95% CI, 21.52-278.38; P = .001) were independently associated with a greater risk of hospital mortality. CONCLUSIONS: The risk of death is exceptionally high among patients with septic shock attributed to Candida infection. Efforts aimed at timely source control and antifungal treatment are likely to be associated with improved clinical outcomes.

Pneumonia occurring outside of the hospital setting has traditionally been categorized as community-acquired pneumonia (CAP). However, when pneumonia is associated with health care risk factors (prior hospitalization, dialysis, residing in a nursing home, immunocompromised state), it is now more appropriately classified as a health care-associated pneumonia (HCAP). The relative incidences of CAP and HCAP among patients requiring hospital admission is not well described. The objective of this retrospective cohort study, involving 639 patients with culture-positive CAP and HCAP admitted between 1 January 2003 and 31 December 2005, was to characterize the incidences, microbiology, and treatment patterns for CAP and HCAP among patients requiring hospital admission. HCAP was more common than CAP (67.4% versus 32.6%). The most common pathogens identified overall included methicillin-resistant Staphylococcus aureus (24.6%), Streptococcus pneumoniae (20.3%), Pseudomonas aeruginosa (18.8%), methicillin-sensitive Staphylococcus aureus (13.8%), and Haemophilus influenzae (8.5%). The hospital mortality rate was statistically greater among patients with HCAP than among those with CAP (24.6% versus 9.1%; P < 0.001). Administration of inappropriate initial antimicrobial treatment was statistically more common among HCAP patients (28.3% versus 13.0%; P < 0.001) and was identified as an independent risk factor for hospital mortality. Our study found that the incidence of HCAP was greater than that of CAP among patients with culture-positive pneumonia requiring hospitalization at Barnes-Jewish Hospital. Patients with HCAP were more likely to initially receive inappropriate antimicrobial treatment and had a greater risk of hospital mortality. Health care providers should differentiate patients with HCAP from those with CAP in order to provide more appropriate initial antimicrobial therapy.

OBJECTIVE: To determine the attributable cost and length of stay of intensive care unit (ICU)-acquired, catheter-associated bloodstream infections from a hospital-based cost perspective, after adjusting for potential confounders. DESIGN: Patients admitted to the ICU between January 19, 1998, and July 31, 2000, were observed prospectively for the occurrence of catheter-associated bloodstream infections. Hospital costs were obtained from the hospital cost accounting database. SETTING: The medical and surgical ICUs at a 500-bed suburban, tertiary care hospital. PATIENTS: Patients requiring central venous catheterization while in the ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We measured occurrence of catheter-associated bloodstream infection, in-hospital mortality rate, total ICU and hospital lengths of stay, and total hospital costs. Catheter-associated bloodstream infection occurred in 41 of 1,132 patients (3.6 cases per 1000 catheter days). Patients with catheter-associated bloodstream infection had significantly higher unadjusted ICU length of stay (median, 24 vs. 5 days; p < .001), hospital length of stay (median, 45 vs. 11 days; p < .001), mortality rate (21 [51%] vs. 301 [28%], p = .001), and total hospital costs (83,544 dollars vs. 23,803 dollars, p < .001). Controlling for other factors that may affect costs and lengths of stay, catheter-associated bloodstream infections resulted in an attributable cost of 11,971 dollars (95% confidence interval, 6,732 dollars-18,352 dollars), ICU length of stay of 2.41 days (95% confidence interval, 0.08-3.09 days), and hospital length of stay of 7.54 days (95% confidence interval, 3.99-11.09 days). CONCLUSIONS: Patients with catheter-associated bloodstream infection had significantly longer ICU and hospital lengths of stay, with higher unadjusted total mortality rate and hospital cost compared with uninfected patients. After adjusting for underlying severity of illness, the attributable cost of catheter-associated bloodstream infection was approximately 11,971 dollars.

BACKGROUND: Millions of patients who survive medical and surgical general intensive care unit care every year experience newly acquired long-term cognitive impairment and profound physical and functional disabilities. To overcome the current reality in which patients receive inadequate rehabilitation, we devised a multifaceted, in-home, telerehabilitation program implemented using social workers and psychology technicians with the goal of improving cognitive and functional outcomes. METHODS: This was a single-site, feasibility, pilot, randomized trial of 21 general medical/surgical intensive care unit survivors (8 controls and 13 intervention patients) with either cognitive or functional impairment at hospital discharge. After discharge, study controls received usual care (sporadic rehabilitation), whereas intervention patients received a combination of in-home cognitive, physical, and functional rehabilitation over a 3-month period via a social worker or master's level psychology technician utilizing telemedicine to allow specialized multidisciplinary treatment. Interventions over 12 wks included six in-person visits for cognitive rehabilitation and six televisits for physical/functional rehabilitation. Outcomes were measured at the completion of the rehabilitation program (i.e., at 3 months), with cognitive functioning as the primary outcome. Analyses were conducted using linear regression to examine differences in 3-month outcomes between treatment groups while adjusting for baseline scores. RESULTS: Patients tolerated the program with only one adverse event reported. At baseline both groups were well-matched. At 3-month follow-up, intervention group patients demonstrated significantly improved cognitive executive functioning on the widely used and well-normed Tower test (for planning and strategic thinking) vs. controls (median [interquartile range], 13.0 [11.5-14.0] vs. 7.5 [4.0-8.5]; adjusted p < .01). Intervention group patients also reported better performance (i.e., lower score) on one of the most frequently used measures of functional status (Functional Activities Questionnaire at 3 months vs. controls, 1.0 [0.0 -3.0] vs. 8.0 [6.0-11.8], adjusted p = .04). CONCLUSIONS: A multicomponent rehabilitation program for intensive care unit survivors combining cognitive, physical, and functional training appears feasible and possibly effective in improving cognitive performance and functional outcomes in just 3 months. Future investigations with a larger sample size should be conducted to build on this pilot feasibility program and to confirm these results, as well as to elucidate the elements of rehabilitation contributing most to improved outcomes.

BACKGROUND: Influenza vaccination of health care workers has been recommended since 1984. Multiple strategies to enhance vaccination rates have been suggested, but national rates have remained low. METHODS: BJC HealthCare is a large Midwestern health care organization with approximately 26,000 employees. Because organizational vaccination rates remained below target levels, influenza vaccination was made a condition of employment for all employees in 2008. Medical or religious exemptions could be requested. Predetermined medical contraindications include hypersensitivity to eggs, prior hypersensitivity reaction to influenza vaccine, and history of Guillan-Barré syndrome. Medical exemption requests were reviewed by occupational health nurses and their medical directors. Employees who were neither vaccinated nor exempted by 15 December 2008 were not scheduled for work. Employees still not vaccinated or exempt by 15 January 2009 were terminated. RESULTS: Overall, 25,561 (98.4%) of 25,980 active employees were vaccinated. Ninety employees (0.3%) received religious exemptions, and 321 (1.2%) received medical exemptions. Eight employees (0.03%) were not vaccinated or exempted. Reasons for medical exemption included allergy to eggs (107 [33%]), prior allergic reaction or allergy to other vaccine component (83 [26%]), history of Guillan-Barré syndrome (15 [5%]), and other (116 [36%]), including 14 because of pregnancy. Many requests reflected misinformation about the vaccine. CONCLUSIONS: A mandatory influenza vaccination campaign successfully increased vaccination rates. Fewer employees sought medical or religious exemptions than had signed declination statements during the previous year. A standardized medical exemption request form would simplify the request and review process for employees, their physicians, and occupational health and will be used next year.

Hip dysplasia is a leading precursor of osteoarthritis and is seen in 20% to 40% of patients with osteoarthritis of the hip. An increase in mechanical stress on the cartilage matrix with failure of the acetabular labrum represents the major pathomechanism of degeneration. Because the prevalence of associated femoral deformities is high (>50%), the structural anatomy of the dysplastic hip must be assessed in multiple planes using radiographs and, if needed, advanced imaging modalities. Acetabular osteotomy (periacetabular and/or rotational) is the most commonly used procedure for the treatment of the majority of dysplastic hips in adults. Modern total hip replacement remains an excellent option for the more arthritic joints. Difficulties can arise from anatomical abnormalities and previous operations.

The optimal approach for empirical antibiotic therapy in patients with severe sepsis and septic shock remains controversial. A retrospective cohort study was conducted in the intensive care units of a university hospital. The data from 760 patients with severe sepsis or septic shock associated with Gram-negative bacteremia was analyzed. Among this cohort, 238 (31.3%) patients received inappropriate initial antimicrobial therapy (IIAT). The hospital mortality rate was statistically greater among patients receiving IIAT compared to those initially treated with an appropriate antibiotic regimen (51.7% versus 36.4%; P < 0.001). Patients treated with an empirical combination antibiotic regimen directed against Gram-negative bacteria (i.e., beta-lactam plus aminoglycoside or fluoroquinolone) were less likely to receive IIAT compared to monotherapy (22.2% versus 36.0%; P < 0.001). The addition of an aminoglycoside to a carbapenem would have increased appropriate initial therapy from 89.7 to 94.2%. Similarly, the addition of an aminoglycoside would have increased the appropriate initial therapy for cefepime (83.4 to 89.9%) and piperacillin-tazobactam (79.6 to 91.4%). Logistic regression analysis identified IIAT (adjusted odds ratio [AOR], 2.30; 95% confidence interval [CI] = 1.89 to 2.80) and increasing Apache II scores (1-point increments) (AOR, 1.11; 95% CI = 1.09 to 1.13) as independent predictors for hospital mortality. In conclusion, combination empirical antimicrobial therapy directed against Gram-negative bacteria was associated with greater initial appropriate therapy compared to monotherapy in patients with severe sepsis and septic shock. Our experience suggests that aminoglycosides offer broader coverage than fluoroquinolones as combination agents for patients with this serious infection.

OBJECTIVE: To conduct an intervention trial of a "best practices" musculoskeletal injury prevention program designed to safely lift physically dependent nursing home residents. DESIGN: A pre-post intervention trial and cost benefit analysis at six nursing homes from January 1995 through December 2000. The intervention was established in January 1998 and injury rates, injury related costs and benefits, and severity are compared for 36 months pre-intervention and 36 months post-intervention. PARTICIPANTS: A dynamic cohort of all nursing staff (n = 1728) in six nursing homes during a six year study period. INTERVENTION: "Best practices" musculoskeletal injury prevention program consisting of mechanical lifts and repositioning aids, a zero lift policy, and employee training on lift usage. MAIN OUTCOME MEASURES: Injury incidence rates, workers' compensation costs, lost work day injury rates, restricted work day rates, and resident assaults on caregivers, annually from January 1995 through December 2000. RESULTS: There was a significant reduction in resident handling injury incidence, workers' compensation costs, and lost workday injuries after the intervention. Adjusted rate ratios were 0.39 (95% confidence interval (CI) 0.29 to 0.55) for workers' compensation claims, 0.54 (95% CI 0.40 to 0.73) for Occupational Safety and Health Administration (OSHA) 200 logs, and 0.65 (95% CI 0.50 to 0.86) for first reports of employee injury. The initial investment of $158 556 for lifting equipment and worker training was recovered in less than three years based on post-intervention savings of $55 000 annually in workers' compensation costs. The rate of post-intervention assaults on caregivers during resident transfers was down 72%, 50%, and 30% based on workers' compensation, OSHA, and first reports of injury data, respectively. CONCLUSIONS: The "best practices" prevention program significantly reduced injuries for full time and part time nurses in all age groups, all lengths of experience in all study sites.

BACKGROUND: In January 2008, the Centers for Disease Control and Prevention began a nationwide investigation of severe adverse reactions that were first detected in a single hemodialysis facility. Preliminary findings suggested that heparin was a possible cause of the reactions. METHODS: Information on clinical manifestations and on exposure was collected for patients who had signs and symptoms that were consistent with an allergic-type reaction after November 1, 2007. Twenty-one dialysis facilities that reported reactions and 23 facilities that reported no reactions were included in a case-control study to identify facility-level risk factors. Unopened heparin vials from facilities that reported reactions were tested for contaminants. RESULTS: A total of 152 adverse reactions associated with heparin were identified in 113 patients from 13 states from November 19, 2007, through January 31, 2008. The use of heparin manufactured by Baxter Healthcare was the factor most strongly associated with reactions (present in 100.0% of case facilities vs. 4.3% of control facilities, P<0.001). Vials of heparin manufactured by Baxter from facilities that reported reactions contained a contaminant identified as oversulfated chondroitin sulfate (OSCS). Adverse reactions to the OSCS-contaminated heparin were often characterized by hypotension, nausea, and shortness of breath occurring within 30 minutes after administration. Of 130 reactions for which information on the heparin lot was available, 128 (98.5%) occurred in a facility that had OSCS-contaminated heparin on the premises. Of 54 reactions for which the lot number of administered heparin was known, 52 (96.3%) occurred after the administration of OSCS-contaminated heparin. CONCLUSIONS: Heparin contaminated with OSCS was epidemiologically linked to adverse reactions in this nationwide outbreak. The reported clinical features of many of the cases further support the conclusion that contamination of heparin with OSCS was the cause of the outbreak.

BACKGROUND: A gap exists between patients' desire to be told about medical errors and present practice. Little is known about how physicians approach disclosure. The objective of the present study was to describe how physicians disclose errors to patients. METHODS: Mailed survey of 2637 medical and surgical physicians in the United States (Missouri and Washington) and Canada (national sample). Participants received 1 of 4 scenarios depicting serious errors that varied by specialty (medical and surgical scenarios) and by how obvious the error would be to the patient if not disclosed (more apparent vs less apparent). Five questions measured what respondents would disclose using scripted statements. RESULTS: Wide variation existed regarding what information respondents would disclose. Of the respondents, 56% chose statements that mentioned the adverse event but not the error, while 42% would explicitly state that an error occurred. Some physicians disclosed little information: 19% would not volunteer any information about the error's cause, and 63% would not provide specific information about preventing future errors. Disclosure was affected by the nature of the error and physician specialty. Of the respondents, 51% who received the more apparent errors explicitly mentioned the error, compared with 32% who received the less apparent errors (P<.001); 58% of medical specialists explicitly mentioned the error, compared with 19% of surgical specialists (P<.001). Respondents disclosed more information if they had positive disclosure attitudes, felt responsible for the error, had prior positive disclosure experiences, and were Canadian. CONCLUSIONS: Physicians vary widely in how they would disclose errors to patients. Disclosure standards and training are necessary to meet public expectations and promote professional responsibility following errors.

Moisture-associated skin damage (MASD) is caused by prolonged exposure to various sources of moisture, including urine or stool, perspiration, wound exudate, mucus, saliva, and their contents. MASD is characterized by inflammation of the skin, occurring with or without erosion or secondary cutaneous infection. Multiple conditions may result in MASD; 4 of the most common forms are incontinence-associated dermatitis, intertriginous dermatitis, periwound moisture-associated dermatitis, and peristomal moisture-associated dermatitis. Although evidence is lacking, clinical experience suggests that MASD requires more than moisture alone. Instead, skin damage is attributable to multiple factors, including chemical irritants within the moisture source, its pH, mechanical factors such as friction, and associated microorganisms. To prevent MASD, clinicians need to be vigilant both in maintaining optimal skin conditions and in diagnosing and treating minor cases of MASD prior to progression and skin breakdown.

BACKGROUND: Health care workers incur frequent injuries resulting from patient transfer and handling tasks. Few studies have evaluated the effectiveness of mechanical lifts in preventing injuries and time loss due to these injuries. METHODS: We examined injury and lost workday rates before and after the introduction of mechanical lifts in acute care hospitals and long-term care (LTC) facilities, and surveyed workers regarding lift use. RESULTS: The post-intervention period showed decreased rates of musculoskeletal injuries (RR = 0.82, 95% CI: 0.68-1.00), lost workday injuries (RR = 0.56, 95% CI: 0.41-0.78), and total lost days due to injury (RR = 0.42). Larger reductions were seen in LTC facilities than in hospitals. Self-reported frequency of lift use by registered nurses and by nursing aides were higher in the LTC facilities than in acute care hospitals. Observed reductions in injury and lost day injury rates were greater on nursing units that reported greater use of the lifts. CONCLUSIONS: Implementation of patient lifts can be effective in reducing occupational musculoskeletal injuries to nursing personnel in both LTC and acute care settings. Strategies to facilitate greater use of mechanical lifting devices should be explored, as further reductions in injuries may be possible with increased use.

OBJECTIVE: Depressive disorders are among the most common medical disorders seen in primary care practice. The Center for Epidemiologic Studies-Depression (CES-D) scale is one of the measures commonly suggested for detecting depression in these clinics. However, to our knowledge, there have been no previous studies examining the validity of the CES-D among low-income women attending primary care clinics. METHOD: Low-income women attending public primary care clinics (n = 179, ages 20-77) completed the CES-D and the Diagnostic Interview Schedule for the DSM-IV (DIS-IV). RESULTS: The results supported the validity of the CES-D. The standard cut-score of 16 and above yielded a sensitivity of .95 and specificity of .70 in predicting Major Depressive Disorder (MDD). However, over two-thirds of those who screened positive did not meet criteria for MDD (positive predictive value = .28). The standard cut-score appears valid, but inefficient for depression screening in this population. An elevated cut-score of 34 yielded a higher specificity (.95) and over 50 percent of the patients who screened positive had a MDD (positive predictive value = .53), but at great cost to sensitivity (.45). CONCLUSION: Results indicated that the CES-D appears to be as valid for low-income, minority women as for any other demographic group examined in the literature. Despite similar validity, the CES-D appears to be inadequate for routine screening in this population. The positive predictive value remains very low no matter which cut-scores are used. The costs of the false positive rates could be prohibitive, especially in similar public primary care settings.

In 2009, a multinational group of clinicians was charged with reviewing and evaluating the research base pertaining to incontinence-associated dermatitis (IAD) and synthesizing this knowledge into best practice recommendations based on existing evidence. This is the first of 2 articles focusing on IAD; it updates current research and identifies persistent gaps in our knowledge. Our literature review revealed a small but growing body of evidence that provides additional insight into the epidemiology, etiology, and pathophysiology of IAD when compared to the review generated by the first IAD consensus group convened 5 years earlier. We identified research supporting the use of a defined skin care regimen based on principles of gentle perineal cleansing, moisturization, and application of a skin protectant. Clinical experience also supports application of an antifungal powder, ointment, or cream in patients with evidence of cutaneous candidiasis, aggressive containment of urinary or fecal incontinence, and highly selective use of a mild topical anti-inflammatory product in selected cases. The panel concluded that research remains limited and additional studies are urgently needed to enhance our understanding of IAD and to establish evidence-based protocols for its prevention and treatment.

BACKGROUND AND PURPOSE: The purpose of this study was to examine the interrater reliability of measurements obtained by examiners administering tests proposed to be important for classifying low back pain (LBP) problems. SUBJECTS: Ninety-five subjects with LBP (41 men, 54 women) and 43 subjects without LBP (17 men, 26 women) were examined by 5 therapists trained in the techniques used. METHODS: A manual was developed by the first author that described the clinical examination procedures. The therapists were trained by the first author in the test procedures and definitions. The training included instruction through videotapes, practice and a written examination. Each examination was conducted by a pair of therapists. Within a pair, a therapist was the primary examiner for half of the subjects and an observer was the primary examiner for half of the subjects. Examination findings were recorded independently, without discussion. RESULTS: Percentage of agreement and generalized kappa coefficients were used to analyzed the data. Kappa values were > or = .75 for all 28 items related to the symptoms elicited and > or = .40 for 72% of the 25 items related to alignment and movement. CONCLUSION AND DISCUSSION: The results suggest that experienced therapist who had trained together were able to agree on the results of examinations and obtain an acceptable level of reliability. Future work should focus on testing of reliability when more than one therapist performs the examination and when therapist not trained by the test developer to administer the examination perform the tests.

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.
