The role of hospital profit status in pediatric spleen injury management

BACKGROUND: Evidence suggests that over 90% of pediatric splenic injuries can be successfully managed nonoperatively. Although pediatric hospitals have rapidly adopted nonoperative management, variability exists among other types of hospitals. OBJECTIVES: We tested 2 a priori hypotheses: (1) spleen-injured children are more likely to receive splenectomy in for-profit hospitals than in not-for-profit hospitals; and (2) hospital charges for spleen cases are greater in for-profit hospital than in not-for-profit hospitals. RESEARCH DESIGN: Multivariable regression was performed with data from the Kid's Inpatient Database (KID) for years 2000 and 2003, controlling for patient and hospital characteristics. Children (0-18 years) hospitalized with a blunt traumatic (noniatrogenic) spleen injury in any of the states participating in KID (N = 5061), including adult and pediatric hospitals. Main outcome measures were splenectomy and hospital charges. RESULTS: A total of 756 children (14.9%) received splenectomies within 1 day of arrival. Splenectomy was found to be more likely among children treated at for-profit hospitals [odds ratio (OR), 1.75; 95% confidence interval (CI), 1.14-2.67] than among children treated in not-for-profit general hospitals. Splenectomies were much less common in children's hospitals (OR, 0.14; 95% CI, 0.05-0.41) than in not-for-profit general hospitals. Hospital charges for all spleen-injured children (regardless of treatment) were significantly greater in for-profit hospitals than in not-for-profit hospitals. CONCLUSIONS: For-profit hospitals seem to be trailing not-for-profit hospitals in the adoption of spleen-conserving management practices. The cost of caring for a child with a splenic injury also seems greater at for-profit hospitals, regardless of management path (ie, splenectomy vs. nonoperative management).     

Minimal social network effects evident in cancer screening behavior

BACKGROUND:

Social networks may influence screening behaviors. We assessed whether screening for breast, prostate, or colorectal cancer is influenced by the actual screening behaviors of siblings, friends, spouses, and coworkers.

METHODS:

We conducted an observational study using Framingham Heart Study data to assess screening for eligible individuals during the late 1990s. We used logistic regression to determine whether the probability of screening for breast, prostate, or colorectal cancer was influenced by the proportion of siblings, friends, and coworkers who had the same screening, as well as spouse's screening for colorectal cancer, adjusting for other factors that might influence screening rates.

RESULTS:

Among 1660 women aged 41‐70 years, 71.7% reported mammography in the previous year; among 1217 men aged 51‐70 years, 43.3% reported prostate‐specific antigen testing in the previous year; and among 1426 men and women aged 51‐80 years, 46.9% reported stool blood testing and/or sigmoidoscopy in the previous year. An increasing proportion of sisters who had mammography in the previous year was associated with mammography screening in the ego (odds ratio [OR], 1.034; 95% confidence interval [CI], 1.000‐1.065 for each 10% increase). A spouse with recent screening was associated with more colorectal cancer screening (OR, 1.65; 95% CI, 1.39‐1.98 vs unmarried). Otherwise, screening behaviors of siblings, friends, and coworkers were not associated with screening in the ego.

CONCLUSIONS:

Aside from a slight increase in breast cancer screening among women whose sisters were screened and colorectal cancer screening if spouses were screened, the screening behavior of siblings, friends, or coworkers did not influence cancer screening behaviors.

Smoking cessation interventions for adolescents: a systematic review

OBJECTIVE: To conduct a systematic review of controlled trials for adolescent smoking cessation. METHODS: Online bibliographic databases were searched as of June 2002, and reference lists from review articles and the selected articles were also reviewed for potential studies. The methodology and findings of all retrieved articles were critically evaluated. Data were extracted from each article regarding study methods, intervention studied, outcomes measured, and results. RESULTS: The abstracts or full-text articles of 281 relevant studies were examined, of which six met the selection criteria. Included were three school-based studies, a study in pregnant adolescent girls, a hospital-based study, and a trial of laser acupuncture. All three of the school-based studies reported significant impacts on cessation rates, although only one of these was a randomized trial. None of the studies had follow-up times of >5.2 months. CONCLUSIONS: There is very limited evidence demonstrating efficacy of smoking-cessation interventions in adolescents, and no evidence on the long-term effectiveness of such interventions. Smoking-cessation interventions that have proven most effective in adults, such as nicotine replacement and antidepressant use, have not been studied in adolescents in a controlled manner.     

Prevention of smoking-related deaths in the United States

BACKGROUND: Tobacco is the leading cause of death in the United States. The majority of people who smoke begin before age 18. OBJECTIVE: Determine the number of smoking-attributable deaths and years of potential life lost (YPLL) in adults that might be saved through interventions to reduce smoking prevalence among children and adolescents. METHODS: Calculation of the smoking-attributable mortality and years of potential life lost by age 85 among the cohort of people aged 18 in 2000. RESULTS: By age 85, there would be 127,670 smoking-attributable deaths among women and 284,502 deaths among men, for a total 412,172 smoking-attributable deaths in the United States among the cohort of 3,964,704 people aged 18 years alive in 2000. Through large-scale multimedia campaigns and a $1 increase in the price per pack of cigarettes, smoking prevalence could be reduced by 26% and would result in an annual savings of 108,466 lives and 1.6 million YPLL. CONCLUSIONS: Interventions to decrease smoking prevalence among children and adolescents can have large effects on adult mortality.     

Longitudinal analysis of large social networks: estimating the effect of health traits on changes in friendship ties

We develop novel mixed effects models to examine the role of health traits on the status of peoples' close friendship nominations in the Framingham Heart Study. The health traits considered are both mutable (body mass index (BMI), smoking, blood pressure, body proportion, muscularity, and depression) and, for comparison, basically immutable (height, birth order, personality type, only child, and handedness); and the traits have varying degrees of observability. We test the hypotheses that existing ties (i.e. close friendship nominations) are more likely to dissolve between people with dissimilar (mutable and observable) health traits whereas new ties are more likely to form between those with similar (mutable and observable) traits while controlling for persons' age, gender, geographic separation, and education. The mixed effects models contain random effects for both the nominator (ego) and nominated (alter) persons in a tie to account for the fact that people were involved in multiple relationships and contributed observations at multiple exams. Results for BMI support the hypotheses that people of similar BMI are less likely to dissolve existing ties and more likely to form ties, while smoker to non-smoker ties were the least likely to dissolve and smoker to smoker ties were the most likely to form. We also validated previously known findings regarding homophily on age and gender, and found evidence that homophily also depends upon geographic separation.
