Injuries in sports, including professional American football, are a major public health problem affecting millions of young and adult athletes around the world each year. While most injuries are minor, some end seasons, careers, and may even result in long-term disability. No outcomes databases exist that focus on injuries in the National Football League (NFL). We sought to develop a database that’s longitudinal and includes key injury impact outcomes. Four years of data including information on any player that played 1+ regular season games between 2010 and 2013 were adapted from NFL.com, ESPN.com, TSN.com and several other reputable online sources. Five different and unique data types, all capable of being merged with one another and used in longitudinal analyses, were stored as SAS datasets: Player Background (e.g., age, weight, position), Games Played, NFL Injury Report, Injured Reserve List, and Schedule and Conditions (e.g., field surface, weather conditions, referee). Data from the NFL Injury Report and Injured Reserve List contain every significant injury to NFL players during the 4-year period including concussions, knees, ankles, hamstrings, etc. Injury Impacts include games missed due to injuries as well as season- and career-ending injuries. Data on 3,193 unique NFL players are included in the database. About 7,700 player-seasons are captured that cover nearly 91,000 player-games. About 18,500 Injury Reports are recorded on these players resulting in more than 6,000 missed games. In addition, almost all 959 Injured Reserve List injuries are season-ending and significantly raise the risk of ending a player’s career. The L-NFL-III database can be a useful tool for epidemiological and outcomes research related to injuries in the NFL. In 4-year longitudinal analyses, this database was successful in identifying a large number of missed games due to injuries, as well other critical outcomes including season- and career-ending injuries.
BACKGROUNDMultiple options are available for closure of hysterectomy incisions. This study compared postoperative clinical and economic outcomes using topical skin adhesive (2-octyl cyanoacrylate; OCA) vs. conventional skin closure in women undergoing total abdominal hysterectomy.METHODSA multi-hospital administrative database was used to identify women discharged in 2005 who had undergone total abdominal hysterectomy. Patients, classified by skin closure as suture (n = 21,201), staples (n = 23,441), OCA (n = 880), or staples + OCA (n = 489), were compared on length of inpatient stay (LOS), total inpatient cost, and non-prophylactic antibiotic treatment after day four.RESULTSThe unadjusted mean LOS was 3.9, 4.5, 3.7, and 5.2 days for suture, staples, OCA, and staples + OCA, respectively; and the percentages of patients having antibiotic treatment were 12.93, 17.51, 11.14, and 23.72. There were overall differences in adjusted mean LOS, mean total cost, and antibiotic treatment (p < 0.0001). Pairwise comparisons indicated no difference between sutures and OCA, whereas the outcomes for each of the non-staple groups were more favorable than those for the staple group (p < 0.01). Results were similar in adjusted comparisons, with pairwise comparisons between OCA and staples at or near the threshold for significance.CONCLUSIONS2-octyl cyanoacrylate appears to be a safe and cost-effective alternative to topical sutures for patients having total abdominal hysterectomy. There were less favorable outcomes in groups receiving staples.
The objective of this study was to undertake a retrospective analysis of claims data of diabetic foot ulcer (DFU) patients to determine the rates of amputation and identify the risk and protective factors. Rates of amputation were calculated in patients diagnosed with DFU in the MEDSTAT Marketscan database between January 2000 and December 2002, who had prediagnosis coverage of 90 days. A nested case-control study was conducted using a 1 : 10 ratio of amputee cases to randomly selected nonamputee controls matched on follow-up days. The association of co-morbid conditions, demographic factors, and severity (5+ outpatient claims for DFU) on amputation was estimated by adjusted odds ratios (AOR) with 95% confidence intervals (CIs). The 5911 eligible patients yielded an incidence density rate of 2.30 amputations per 100 person years (95% CI = 1.91, 2.77). The 116 cases and 1153 controls averaged 307.3 and 308.5 observation days, respectively. Amputation was significantly increased by male gender (AOR 1.98), Charlson co-morbidity scores of 4-5 and 6+ (AOR = 2.89 and 5.36, respectively), renal disease (AOR = 2.11), peripheral vascular disease (AOR = 2.67), and 5+ outpatient DFU services (AOR = 2.17). Practitioners may consider more aggressive care and earlier referral to specialists for DFU patients who fit risk profiles for amputation, which include peripheral vascular disease, multiple co-morbid conditions, and repeated outpatient DFU services.
Summary. We aimed to determine rates of treatment with alpha‐interferon medication in patients diagnosed with hepatitis C virus (HCV), to ascertain the prevalence of selected conditions that could influence initiation of interferon treatment, and to examine the association between the presence of these conditions and interferon treatment. A nested case–control design was used in California Medicaid (Medi‐Cal) claims data covering the period from 1 January 1996 to 30 June 2002. Interferon‐treated cases and non‐treated controls were selected in a 1 : 2 ratio that matched the length of the observation period and year of index HCV diagnosis. Predictor variables examined in bivariate and multivariate analyses included demographics, substance abuse and dependence, psychotropic drug use, selected chronic conditions and medical utilization. The proportion of eligible subjects diagnosed with HCV and treated with interferon ranged from 10.7 to 13.9%. There were 529 treated cases that met the eligibility criteria and 1058 non‐treated HCV patients selected as controls. Multivariate factors that increased the likelihood of treatment were a liver biopsy, a diagnosis of mild liver disease, a diagnosis of psoriasis, antidepressant use and classification of race/ethnicity as ‘other’. A decreased likelihood of treatment was linked to age ≥65 years, a diagnosis of kidney disease, one to four emergency visits and five or more emergency visits. The proportion of patients receiving interferon treatment in the Medi‐Cal‐insured population was low compared with published rates in HCV patients in other general medical settings. The diverse factors linked to initiation of HCV therapy raise compelling questions for further research.
BACKGROUND:Acetylcholinesterase inhibitors (AChEI) are now widely used as treatment for Alzheimer's disease (AD). Their cholinomimetic action has the potential to influence sleep quality and donepezil has been associated with sleeprelated adverse events. This study examined whether galantamine, an AChEI with nicotinic modulation, is associated with nighttime sleeprelated problems. METHODS:Using data combined from three randomized, double-blind trials, galantamine (GAL) and placebo-treated patients were compared on sleep-related adverse events and concomitant medications. Verbatim descriptions by patients, as recorded by physicians, were used to classify adverse events into insomnia/sleep problems and nightmares/dreams. New concomitant medications findings from double-blind, placebo-controlled were counted when prescribed for sleep-related indications. Treatment arms were 705 subjects on GAL 24 mg (12 mg BID), 279 on GAL 16 mg (8 mg BID), and 714 on placebo. RESULTS:Comparing GAL 24, GAL 16, and placebo arms, the respective rates for insomnia/sleep problems were 2.6, 1.1, and 2.2% and for nightmares were 1.1, 0.4, and 0.1%. Comparisons between GAL arms and placebo were not significant, with the exception of GAL 24 for nightmares (p = 0.02). However, due to the low frequency of nightmares in each group the clinical relevance of this difference is unknown. Rates of use for all concomitant medications indicated for sleep were 5.4, 2.9, and 4.6%, respectively, with no significant differences between GAL arms and placebo. CONCLUSION:These results support previous studies that have shown maintenance of good sleep hygiene during treatment with galantamine.
BACKGROUND:In clinical trials, sleep problems have been identified as side effects of donepezil, an acetylcholinesterase (AChE)-inhibiting medication for the treatment of Alzheimer's disease (AD). Poor sleep quality can exacerbate behavior problems among patients and add to the burden experienced by their caregivers. We examined the relationship between co-use of donepezil and hypnotics in a large sample of persons with AD living in the community.METHOD:This secondary data analysis used cross-sectional subjects from a multiwave, consumer-based survey of AD caregivers conducted in 1997 and 1998. Rates of hypnotic use among users and non-users of donepezil were compared using chi-square analysis for independent samples, and multivariate logistic regression was used to identify significant independent correlates of hypnotic use.RESULTS:A total of 2638 caregivers completed at least 1 study wave. Use of hypnotics was higher in the donepezil subgroup (9.78%) compared with subjects not taking this medication (3.93%). Multivariate analysis demonstrated that donepezil use was independently linked to increased hypnotic use after controlling for the potential confounding effects of disruptive behavior and depressive symptoms (adjusted odds ratio = 3.34, p <.001).CONCLUSION:In this large community sample, donepezil use was statistically linked to increased hypnotic use. Because sleep quality may be a critical issue for persons with AD and their caregivers, more rigorous evaluation of sleep problems linked to AChE-inhibitor treatment is indicated.
We investigated the relationship of caregivers' health-related quality of life (HRQOL) to the burden of caring for patients with Alzheimer disease (AD) and resource utilization. Caregiver HRQOL was assessed using the SF-12 Mental and Physical Summary scores. Compared with a normative, age-adjusted sample, the 2477 caregivers had lower mental and physical scores (for the latter, only those <54 years of age). Increased caregiver mental functioning was associated with caregiver support and perceived quality of patient medical care, fewer hours of caregiving, and fewer patient behavioral symptoms. The burden of caregiving has substantial effects on HRQOL. Interventions that improve AD status and reduce caregiving hours have the potential to improve caregivers' HRQOL.
STUDY OBJECTIVES:To recognize the potential effect of acetylcholinesterase-inhibiting medications on sleep quality when used for the treatment of mild to moderate Alzheimer disease and describe sleep outcomes for patients treated with galantamine.DESIGN:This study examined sleep quality among individuals with mild to moderate Alzheimer disease using data from a 3-month, double-blind, flexible-dose trial of galantamine. The hypothesis was no difference in sleep quality between galantamine- and placebo-treated subjects.PATIENTS:136 patients treated with galantamine 24 mg per day and 125 patients treated with placebo.MEASUREMENTS:Based on caregiver reports, the sleep-related outcome measures were the Pittsburgh Sleep Quality Index and the sleep disorders item from the Neuropsychiatric Inventory. Using a P-value of 0.05 (2-tailed), analysis of covariance was used to compare treatments on mean change from baseline to month 3 (Pittsburgh Sleep Quality Index) or mean score at month 3 (Neuropsychiatric Inventory), adjusted for baseline score and investigator.RESULTS:Both patient groups had an average age of 75 years and a mean Mini-Mental Status Examination score of 20. There were no significant differences between groups on the Pittsburgh Sleep Quality Index total (P=0.59) or subscales. For galantamine and placebo, the mean adjusted changes from baseline on the total Pittsburgh Sleep Quality Index were 0.01 and -0.17, respectively. There also was no difference on the Neuropsychiatric Inventory sleep score at month 3 (P=0.51).CONCLUSIONS:Medications to treat Alzheimer disease should maintain sleep quality and have a neutral effect on sleep. These results further confirm the lack of sleep problems associated with galantamine treatment.
BACKGROUND:Managed care organizations (MCOs) will have increased responsibility for the care of large numbers of persons with dementia. There are, however, few studies that inform about decisions of healthcare utilization and expenditures for individuals with dementia in managed care. OBJECTIVES:To examine in a large MCO whether people diagnosed with dementia have higher healthcare utilization and costs than enrollees without dementia. DESIGN:A retrospective study of medical and prescription claims. SETTING:An MCO covering more than 80,000 Medicare enrollees in four geographical locales between January 1, 1996, and March 31, 1998. SUBJECTS:There were 677 paired cases with and without dementia. Controls were selected randomly and matched to cases on age, gender, and region. MEASUREMENTS:Summed total costs and number of claims accrued during the study period, as well as a breakdown of costs and claims with respect to place of service, were annualized and adjusted for age, gender, and comorbid conditions. Costs and claims were broken down by place of service. RESULTS:Dementia prevalence was 0.83%. Mean total costs were 1.5 times higher for patients with dementia relative to controls ($13,487 vs $9,276, P < .001) when annualized and adjusted for level of comorbidity. Almost 75% of the higher costs among cases were linked to inpatient expenses. CONCLUSIONS:Higher costs for individuals with dementia and disproportionate inpatient costs in this MCO parallel patterns among Medicare enrollees in fee-for-service. The high prevalence of dementia among the oldest old coupled with the high costs of dementia care create very significant clinical and financial incentives for managed care plans to improve the care of members suffering from dementia.
OBJECTIVES. Death rates for community-acquired pneumonia based on relatively small-scale, published studies tend to exceed 15% to 20%. This study reexamined these estimates by using very large, population-based databases. METHODS. Death rates from 1993 associated with community-acquired pneumonia were reexamined with hospital discharge data from all of Washington, Illinois, and Florida. RESULTS. These death rates were substantially lower (7.0%, 8.1%, and 9.7%, respectively) than what appears in the literature. Significant risk factors for dying were being 65 years of age or older (odds ratio [OR] = 2.9), being positive for human immunodeficiency virus (OR = 2.9), and having a high severity of illness (OR = 7.1). CONCLUSION. Sampling bias associated with selection for hospital admissions explain the discrepancy between previous and this study's results.
This multinational, 16-week, randomized, double-blind, placebo-controlled study evaluated the efficacy and safety of low-dose pravastatin in 325 patients with non-insulin-dependent diabetes mellitus (NIDDM) and hypercholesterolemia [serum total cholesterol concentrations of 5.2-7.8 mmol/l (200 to 300 mg/dl)]. Patients were randomized to receive pravastatin 10 mg or matching placebo with doubling of the dose after 8 weeks if predefined target levels for total cholesterol [(i.e., < 5.2 mmol/l (200 mg/dl) or > 15% decrease from baseline] had not been achieved. At Week 16, pravastatin-treated patients showed a 21.4% decrease in serum low-density lipoprotein cholesterol (LDL-C) and a 13.5% reduction in serum total cholesterol (TC) concentrations (p < 0.001 compared with placebo). Levels of triglycerides (TG) were reduced 9.6% during pravastatin treatment (p < 0.05 compared with placebo) while high-density lipoprotein cholesterol (HDL-C) levels were increased 4.4% (p = NS). Adverse events and laboratory test abnormalities were similar among patients treated with pravastatin or placebo. Glycosylated hemoglobin (HbA1C) levels remained unchanged. The results of this study demonstrate that low-dose pravastatin is effective and well tolerated for lowering elevated cholesterol concentrations during short-term treatment of patients with NIDDM and hypercholesterolemia.
There has been limited systematic study of determinants of acute psychiatric hospitalization of children and adolescents. This study reviewed the records of children and adolescents who received emergency mental health services in one New Jersey county during 6 months of 1990 (N = 226). Using a structured form to abstract data, information was obtained on demographics, precipitating problems, past mental health services, substance use, family problems, and disposition. While suicidal behavior was not a predictor of acute hospitalization, the interaction of assaultive and suicidal behavior was predictive. Other contributory factors identified in the multivariate analysis included: child's substance use, family member's substance use, and initial emergency screening site. Recognition of present utilization patterns will facilitate the development of intensive community-based options for those with acute mental health problems.
