Church-based social marketing to motivate older adults to take balance classes for fall prevention: cluster randomized controlled trial.

OBJECTIVE: Determine whether a church-based social marketing program increases older adults' participation in balance classes for fall prevention. METHODS: In 2009-10, 51 churches (7101 total members aged ≥ 60) in Colorado, U.S.A. were randomized to receive no intervention or a social marketing program. The program highlighted benefits of class participation (staying independent, building relationships), reduced potential barriers (providing convenient, subsidized classes), and communicated marketing messages through church leaders, trained "messengers," printed materials and church-based communication channels. Between-group differences in balance class enrollment and marketing message recall among congregants were compared using Wilcoxon Two-Sample Test and regression models. RESULTS: Compared to 25 control churches, 26 churches receiving the social marketing program had a higher median proportion (9.8% vs. 0.3%; p<0.001) and mean number (7.0 vs. 0.5; IRR=11.2 [95%CI: 7.5, 16.8]) of older adult congregants who joined balance classes. Intervention church members were also more likely to recall information about preventing falls with balance classes (AOR=6.2; 95% CI: 2.6, 14.8) and availability of classes locally (AOR=7.7; 95% CI: 2.6, 22.9). CONCLUSIONS: Church-based social marketing effectively disseminated messages about preventing falls through balance classes and, by emphasizing benefits and reducing barriers and costs of participation, successfully motivated older adults to enroll in the classes.

Sensitivity of systemic inflammatory response syndrome for critical illness among ED patients.

BACKGROUND: Little is known about the diagnostic accuracy of systemic inflammatory response syndrome (SIRS) criteria for critical illness among emergency department (ED) patients with and without infection. Our objective was to assess the diagnostic accuracy of SIRS criteria for critical illness in ED patients. METHODS: This was a retrospective cohort study of ED patients at an urban academic hospital. Standardized chart abstraction was performed on a random sample of all adult ED medical patients admitted to the hospital during a 1-year period, excluding repeat visits, transfers, ED deaths, and primary surgical or psychiatric admissions. The binary composite outcome of critical illness was defined as 24 hours or longer in intensive care or inhospital death. Presumed infection was defined as receiving antibiotics within 48 hours of admission. Systemic inflammatory response syndrome criteria were calculated using ED triage vital signs and initial white blood cell count. RESULTS: We studied 1152 patients; 39% had SIRS, 27% had presumed infection, and 23% had critical illness (2% had inhospital mortality, and 22% had ≥24 hours in intensive care). Of patients with SIRS, 38% had presumed infection. Of patients without SIRS, 21% had presumed infection. The sensitivity of SIRS criteria for critical illness was 52% (95% confidence interval [CI], 46%-58%) in all patients, 66% (95% CI, 56%-75%) in patients with presumed infection, and 43% (95% CI, 36%-51%) in patients without presumed infection. CONCLUSIONS: Systemic inflammatory response syndrome at ED triage, as currently defined, has poor sensitivity for critical illness in medical patients admitted from the ED.

Quality-of-life loss of people admitted to burn centers, United States.

PURPOSE: To estimate quality-of-life loss per serious burn survivor in a large U.S. cohort. METHODS: Longitudinal functional assessments of all 1,587 people receiving primary treatment in 5 burn centers between 2000 and 2009 included pre-burn (retrospective), at time of discharge, and 6, 12, and 24 months post-injury. We assessed adults with RAND Short Form (SF) 12 and children with SF-10 or Child Health Questionnaire, the child surveys scored using standard norms-based scoring. A literature review identified 20 quality-adjusted life year utility scorings for SF-12 and 27 scorings for EQ-5d response distributions predicted from SF-12 scores. We computed composite scores for each patient and time period by applying 32 scorings that met quality/non-duplication criteria. RESULTS: Mean quality-of-life scores were 0.805 4 weeks pre-burn, 0.562 at discharge, rebounded through 1 year, and stabilized at 0.735 (0.750 for TBSA burned below 25 %, 0.722 for TBSA burned of 25-50 %, and 0.695 for larger burns). As a percentage of initial levels, burns reduced short-term quality of life by 30 %. Long-term loss averaged 11 %, ranging from 9 % for TBSA burned below 25-13 % for TBSA burned above 50 %. Children recovered faster and more fully. CONCLUSION: Burns cause substantial losses in quality of life, with long-term losses comparable to traumatic brain injury.

Observational studies of patients in the emergency department: a comparison of 4 sampling methods.

STUDY OBJECTIVE: We evaluate the ability of 4 sampling methods to generate representative samples of the emergency department (ED) population. METHODS: We analyzed the electronic records of 21,662 consecutive patient visits at an urban, academic ED. From this population, we simulated different models of study recruitment in the ED by using 2 sample sizes (n=200 and n=400) and 4 sampling methods: true random, random 4-hour time blocks by exact sample size, random 4-hour time blocks by a predetermined number of blocks, and convenience or "business hours." For each method and sample size, we obtained 1,000 samples from the population. Using χ(2) tests, we measured the number of statistically significant differences between the sample and the population for 8 variables (age, sex, race/ethnicity, language, triage acuity, arrival mode, disposition, and payer source). Then, for each variable, method, and sample size, we compared the proportion of the 1,000 samples that differed from the overall ED population to the expected proportion (5%). RESULTS: Only the true random samples represented the population with respect to sex, race/ethnicity, triage acuity, mode of arrival, language, and payer source in at least 95% of the samples. Patient samples obtained using random 4-hour time blocks and business hours sampling systematically differed from the overall ED patient population for several important demographic and clinical variables. However, the magnitude of these differences was not large. CONCLUSION: Common sampling strategies selected for ED-based studies may affect parameter estimates for several representative population variables. However, the potential for bias for these variables appears small.

Perceptions regarding workplace hazards at a veterinary teaching hospital.

OBJECTIVE: To assess perceptions of personnel working at a veterinary teaching hospital regarding risks of occupational hazards and compare those perceptions with assessments made by occupational safety experts. DESIGN: Cross-sectional study. STUDY POPULATION: A representative sample of personnel (n = 90) working at the veterinary teaching hospital at Colorado State University and a panel of 3 occupational safety experts. PROCEDURES: Hospital personnel ranked perceptions of 14 physical, chemical, and biological workplace hazards and listed the injuries, illnesses, and near misses they had experienced. The expert panel provided consensus rankings of the same 14 hazards for 9 sections of the facility. Risk perceptions provided by the 2 sources were compared. RESULTS: Risk perceptions did not differ significantly between hospital personnel and the expert panel for most of the site-specific comparisons (94/126 [75%]). Personnel perceived greater risks for some physical hazards (loud noises, sharps injuries, and ionizing radiation) and some chemical or materials exposures (insecticides or pesticides and tissue digester emissions). In contrast, the expert panel perceived greater risks for physical hazards (bite or crush and restraining and moving animals), chemical exposures (anesthetic waste gas), and biological exposures (Toxoplasma gondii, antimicrobial-resistant bacteria, and allergens). CONCLUSIONS AND CLINICAL RELEVANCE: Participants and safety experts had similar perceptions about occupational risks, but there were important differences where hospital personnel apparently overestimated or underappreciated the risks for workplace hazards. This type of study may be useful in guiding development of optimal workplace safety programs for veterinary hospitals.

Case-based surveillance of influenza hospitalizations during 2004-2008, Colorado, USA.

Colorado became the first state to make laboratory-confirmed influenza-associated hospitalizations a case-based reportable condition in 2004. We summarized surveillance for influenza hospitalizations in Colorado during the first 4 recorded influenza seasons (2004-2008). We highlight the similarities and differences among influenza seasons; no 2 seasons were entirely the same. The 2005-06 influenza season had 2 distinct waves of activity (types A and B), the 2006-07 season was substantially later and milder, and 2007-08 had substantially greater influenza B activity. The case-based surveillance for influenza hospitalizations provides information regarding the time course of seasonal influenza activity, reported case numbers and population-based rates by age group and influenza virus type, and a measure of relative severity. Influenza hospitalization surveillance provides more information about seasonal influenza activity than any other surveillance measure (e.g., surveillance for influenza-like illness) currently in widespread use among states. More states should consider implementing case-based surveillance for influenza hospitalizations.

Neonatal outcomes after elective cesarean delivery.

OBJECTIVE: To examine the outcomes of neonates born by elective repeat cesarean delivery compared with vaginal birth after cesarean (VBAC) in women with one prior cesarean delivery and to evaluate the cost differences between elective repeat cesarean and VBAC. METHODS: We conducted a retrospective cohort study of 672 women with one prior cesarean delivery and a singleton pregnancy at or after 37 weeks of gestation. Women were grouped according to their intention to have an elective repeat cesarean or a VBAC (successful or failed). The primary outcome was neonatal intensive care unit (NICU) admission and measures of respiratory morbidity. RESULTS: Neonates born by cesarean delivery had higher NICU admission rates compared with the VBAC group (9.3% compared with 4.9%, P=.025) and higher rates of oxygen supplementation for delivery room resuscitation (41.5% compared with 23.2%, P<.01) and after NICU admission (5.8% compared with 2.4%, P<.028). Neonates born by VBAC required the least delivery room resuscitation with oxygen, whereas neonates delivered after failed VBAC required the greatest degree of delivery room resuscitation. The costs of elective repeat cesarean were significantly greater than VBAC. However, failed VBAC accounted for the most expensive total birth experience (delivery and NICU use). CONCLUSION: In comparison with vaginal birth after cesarean, neonates born after elective repeat cesarean delivery have significantly higher rates of respiratory morbidity and NICU-admission and longer length of hospital stay. LEVEL OF EVIDENCE: II.

Age at menarche and first pregnancy among psychosocially at-risk adolescents.

We sought to determine which factors influence the association between menarche and conception among adolescent study participants (n = 1030), who demonstrated an earlier age of menarche than did national samples. Age at first sexual intercourse (coitarche) mediated the relationship between age at menarche and first pregnancy among White girls, whereas gynecologic age at coitarche (age at coitarche minus age at menarche) and age at menarche explained the timing of the first pregnancy among Black and Hispanic girls. Pregnancy prevention interventions to delay coitarche should also include reproductive education and contraception.

Colorado dental practitioners' attitudes and practices regarding tobacco-use prevention activities for 8- through 12-year-old patients.

BACKGROUND: Tobacco use is a leading risk factor for oral morbidities and mortalities such as oral cancers and periodontitis. This study characterizes the factors related to dentists and hygienists conducting tobacco-use prevention counseling with 8- through 12-year-old patients. METHODS: The study used a mailed survey of dentists (n = 434), orthodontists (n = 91) and hygienists (n = 160) practicing in Colorado to collect data on the practitioners' tobacco-use prevention counseling activity, demographic characteristics, barriers to counseling and attitudes toward tobacco use. The authors used multiple logistic regression to determine which variables were associated independently with a dental practitioner's counseling children. RESULTS: The response rate was 25.6 percent. Prevalence of tobacco-use prevention counseling for children was low (38 percent for dentists and 44 percent for hygienists). Among dentists, the perception of tobacco use in children as a problem, perceived effectiveness of counseling and perceived role of a dental practitioner in counseling children were associated positively with counseling. Lack of skills was associated negatively with counseling. Among hygienists, perceived role in counseling children was associated positively and lack of time was associated negatively with counseling. CONCLUSIONS: Few dental practitioners counsel 8- through 12-year-old patients about tobacco use. Factors related to counseling appear to be amenable to education of dentists, in particular, regarding the importance of the problem, the effectiveness of counseling and skill development. CLINICAL IMPLICATIONS: Preventing tobacco use among children is integral to promoting patients' oral health. Training dentists through continuing education should increase the frequency of tobacco-use prevention counseling with children by both dentists and hygienists.

Psychological distress after major burn injury.

OBJECTIVE: To track the prevalence and stability of clinically significant psychological distress and to identify potentially modifiable in-hospital symptoms predictive of long-term distress (physical, psychological, and social impairment). METHOD: We obtained data from the Burn Model Systems project, a prospective, multisite, cohort study of major burn injury survivors. The Brief Symptom Inventory (BSI) was used to assess symptoms in-hospital (n = 1232) and at 6 (n = 790), 12 (n = 645), and 24 (n = 433) months post burn. Distress was examined dimensionally (BSI's Global Severity Index (GSI)) and categorically (groups formed by dichotomizing GSI: T score > or =63). Attrition was unrelated to in-hospital GSI score. RESULTS: Significant in-hospital psychological distress occurred in 34% of the patients, and clinically significant and reliable change in symptom severity by follow-up visits occurred infrequently. Principal components analysis of in-hospital distress symptoms demonstrated "alienation" and "anxiety" factors that robustly predicted distress at 6, 12, and 24 months, controlling for correlates of baseline distress. CONCLUSIONS: This is the largest prospective, multisite, cohort study of patients with major burn injury. We found that clinically significant in-hospital psychological distress was common and tends to persist. Two structural components of in-hospital distress seemed particularly predictive of long-term distress. Research is needed to determine if early recognition and treatment of patients with in-hospital psychological distress can improve long-term outcomes.

Acute pain at discharge from hospitalization is a prospective predictor of long-term suicidal ideation after burn injury.

OBJECTIVE: To determine the extent to which pain contributes to risk for suicidal ideation after burn injury. DESIGN: This longitudinal cohort study evaluated participants at discharge, 6 months, and 1 year after burn injury. SETTING: Inpatient rehabilitation units of multiple regional burn centers. PARTICIPANTS: Survivors of major burns (N=128). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Pain severity, assessed using the Medical Outcomes Study 36-Item Short-Form Health Survey bodily pain subscale, and passive and active suicidal ideation, assessed by self-report. RESULTS: At each time point, approximately one quarter to one third of the sample reported some form of suicidal ideation. In logistic regression analyses, pain severity at discharge was the sole consistent predictor of suicidal ideation at follow-up, with greater pain severity being associated with enhanced risk for both passive and active suicidal ideation. These associations were observed even after controlling for discharge mental health. CONCLUSIONS: These are the first findings to suggest an association between acute pain severity and the development and maintenance of suicidal ideation in burn patients. Further research in this area, including the study of improved pain management programs as a prophylaxis against suicidal ideation, may benefit those who are at elevated suicide risk as a consequence of burn injuries.

Barriers to return to work after burn injuries.

OBJECTIVE: To identify barriers to return to work after burn injury as identified by the patient. DESIGN: A cohort study with telephone interview up to 1 year. SETTING: Hospital-based burn centers at 3 national sites. PARTICIPANTS: Hospitalized patients (N=154) meeting the American Burn Association criteria for major burn injury, employed at least 20 hours a week at the time of injury, and with access to a telephone after discharge. INTERVENTION: Patients were contacted via telephone every 2 weeks up to 4 months, then monthly up to 1 year after discharge. MAIN OUTCOME MEASURES: A return to work survey was used to identify barriers that prevented patients from returning to work. A graphic rating scale determined the impact of each barrier. RESULTS: By 1 year, 79.7% of patients returned to work. Physical and wound issues were barriers early after discharge. Although physical abilities continued to be a significant barrier up to 1 year, working conditions (temperature, humidity, safety) and psychosocial factors (nightmares, flashbacks, appearance concerns) became important issues in those with long-term disability. CONCLUSIONS: The majority of patients return to work after a burn injury. Although physical and work conditions are important barriers, psychosocial issues need to be evaluated and treated to optimize return to work.

Assets and liabilities of the Burn Model System data model: a comparison with the National Burn Registry.

OBJECTIVES: To determine whether the Burn Model System (BMS) population is representative of the larger burn population and to investigate threats to internal and external validity in a multicenter longitudinal database of severe burns. DESIGN: Cohort data for the BMS project have been collected since 1994. Follow-up data have been collected at 6, 12, and 24 months postburn. The demographic and burn characteristics of the BMS population were compared with those of patients in the National Burn Registry (NBR). SETTING: The BMS, which collected data for these analyses from 5 regional burn centers in the United States, and the NBR dataset, which is a registry of information collected through the Trauma Registry of the American College of Surgeons and includes data from 70 hospitals in the United States and Canada. PARTICIPANTS: BMS study participants were severely burned patients treated at 1 of the 5 participating burn centers. We compared the BMS population with that of the NBR both in total and filtered to include only patients with comparable injuries. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Comparable demographic and burn characteristics contained in both the NBR and the 5-center BMS longitudinal database and baseline and follow-up distributions of demographic variables and burn characteristics in the BMS database. RESULTS: Although minor deviations in demographic distributions were found between the BMS and NBR and between discharge and follow-up populations, our results show that the BMS population sample is internally and externally valid and is adequate for answering research questions. CONCLUSIONS: Cohort studies examining long-term outcomes have the potential flaw of using a nonrepresentative study population. The BMS population was found to be sufficiently representative, but future analyses will require cautious and purposeful application of statistical adjustment strategies.

The effect of FDA approval of a generic competitor to OxyContin (oxycodone HCl controlled-release) tablets on the abuse of oxycodone.

Controversy exists concerning whether abuse of oxycodone will increase after the introduction of generic controlled-release (CR) oxycodone. We evaluated the effect of FDA approval of generic CR oxycodone on the misuse/abuse of oxycodone, hydrocodone, methadone and morphine utilizing data from eight poison control centers (PCC). PCC intentional exposure (IE) reason codes were used as measures of abuse. Opioid-specific quarterly IE rates (per 100,000 population and per 10,000 patients) were calculated for 1 year before and after approval (March 24, 2004). Changes in regression slopes (1 year before to 1 year after) and in IE rates (1 quarter before to 1 quarter after) were analyzed using Poisson regression. The regression slopes for oxycodone, methadone and morphine did not change after approval but decreased significantly for hydrocodone. None of the prescription opioids' IE rates significantly increased after approval. When changes in oxycodone's IE rates were compared to the other opioids, no statistically significant differences were found, indicating a lack of time-opioid interaction. These results did not vary when population rates or patient rates were used. PCC data indicate that approval of generic CR oxycodone was not followed by an immediate unfavorable effect on the misuse/abuse of oxycodone.

Risk factors for asthma among cosmetology professionals in Colorado.

PROBLEM: After receiving several reports of occupational asthma among cosmetology professionals, we studied the prevalence, work-attributable risk, and tasks associated with asthma in this industry. METHODS: We selected a stratified random sample of cosmeticians, manicurists, barbers, and cosmetologists holding licenses in Colorado for a mail survey instrument. RESULTS: The prevalence of physician-diagnosed asthma among the 1883 respondents (68% response rate) was 9.3%; of these, 67 (38%) developed asthma after entering the cosmetology profession. Multivariate analyses showed that hairstyling, application of artificial nails, and shaving and honing were significantly associated with asthma arising in the course of employment (P < 0.005) with relative risks of 2.6-2.9. CONCLUSIONS: The increased risk of asthma with onset during employment among cosmetologists is probably attributable to their exposure to sensitizers and irritants in tasks demonstrated to be associated with asthma.

Does availability of mental health resources prevent recurrent suicidal behavior? An ecological analysis.

This study examines whether availability of mental health resources in the county of residence is associated with subsequent suicidal behavior after a previous suicide attempt. Among 10,922 individuals who attempted suicide in Colorado between 1998 and 2002, residence in a county that offered a minimum safety-net of mental health services significantly reduced the risk of suicidal behavior for at least 1 year after the index attempt. Safety-net services included mental health treatment, crisis treatment, and case management. These results suggest one strategy for prevention of suicidal behavior that could inform state-level health policy development and resource allocation.

Injuries from slips and trips in construction.

Construction injuries preceded by a slip or trip were documented using data from the building of the Denver International Airport (Denver, Colorado, USA), the largest construction project in the world at the time. Slips and trips occurred at a rate of 5/200,000 h worked accounting for 18% of all injuries and 25% of workers' compensation payments, or more than $10 million. Slips contributed to the vast majority (85%) of same-level falls and over 30% of falls from height, as well as a significant number of musculoskeletal injures sustained after slipping or tripping but without falling. The injury burden would have been under-recognized in analyses of most coded compensation records. In contrast to other types of injuries, the most common contributing factors were environmental in nature including conditions of walking and working surfaces, terrain and weather. Due to the very dynamic nature of construction work, reducing slips and trips will require a focus on environmental and organizational solutions that evolve as the site changes and the construction project evolves.

Uncomplicated acute renal failure and hospital resource utilization: a retrospective multicenter analysis.

BACKGROUND: Although acute renal failure (ARF) complicating nonrenal organ dysfunction in the intensive care unit is associated with significant mortality and hospital costs, hospital resource utilization attributed to uncomplicated ARF is not well known. The goal of this study is to characterize the costs and lengths of stay (LOSs) incurred by hospitalized patients with uncomplicated ARF and their important determining factors. METHODS: We obtained hospital case-mix data sets from 23 Massachusetts hospitals for a 2-year period (1999 to 2000) from the Massachusetts Division of Health Care Finance and Policy. A total of 2,252 records of patients hospitalized with uncomplicated ARF were identified. Patient records of other common medical diagnoses were studied for comparison. RESULTS: Patients hospitalized with uncomplicated ARF incurred median direct hospital costs of 2,600 dollars, median hospital LOS of 5 days, and mortality of 8%. Dialysis was independently associated with significantly greater hospital costs and LOSs for patients with uncomplicated ARF (P < 0.05). Male sex and nonwhite race were associated with significantly lower hospital costs and LOSs, whereas type of hospital had opposing effects on these 2 resource utilization outcomes (P < 0.05). Unadjusted aggregate resource utilization associated with uncomplicated ARF exceeded that of many other common illnesses. CONCLUSION: Demographic and hospital factors, as well as dialysis therapy, are significant determinants of hospital resource utilization for patients with uncomplicated ARF. Uncomplicated ARF appears to incur greater hospital costs and longer LOSs compared with other common medical conditions. Greater focus should be directed toward further understanding of the factors influencing resource utilization for ARF.

Burden of burn: a norm-based inquiry into the influence of burn size and distress on recovery of physical and psychosocial function.

This prospective, longitudinal study examined the influence of baseline physical and psychological burden on serial assessments of health-related quality of life among adults with major burns from three regional burn centers (n = 162). Physical burden groups were defined by % TBSA burned: <10%, 10% to 30%, or >30%. Psychological burden groups were defined by in-hospital distress using the Brief Symptom Inventory Global Severity Index T-score with scores of < 63 or > or = 63. Analyses compared groups across level of burden and with published normative data. Assessments reflected health and function (Short Form 36) during the month before burn, at discharge, and at 6 and 12 months after burn. Physical functioning was significantly more impaired and the rate of physical recovery slower among those with either large physical burden or large psychological burden. Notably, psychosocial functioning also was more impaired and the rate of psychosocial recovery slower among those with greater psychological burden. These results suggest that, in addition to aggressive wound closure, interventions that reduce in-hospital distress may accelerate both physical and psychosocial recovery.

The effect of race/ethnicity on gestational weight gain.

Minority women are gaining more weight than recommended during pregnancy. This study aimed to determine the risk of excessive gestational weight gain (GWG) in Hispanic and Black women compared to non-Hispanic women in Colorado. A retrospective cohort study of all birth records from 2007 to 2010 in Colorado was conducted. The primary outcome was GWG, and the exposure was race/ethnicity. Covariates were marital status, education, intensity of prenatal care, age, parity, tobacco use, alcohol use and years in the US. Chi square and multiple logistic regression was performed. 230,698 records were analyzed. Half of the Hispanic and Black women began their pregnancy overweight or obese. Hispanic women had a 0.84 (95% CI 0.8-0.9) and Black women had a 0.95 (95% CI 0.9-1.0) risk of excessive GWG than NHW women. Pre-pregnancy weight is an independent risk for adverse outcomes. The study findings provide healthcare providers focal points in preconception health care and programming.
