Comprehensive discharge planning and home follow-up of hospitalized elders: a randomized clinical trial

CONTEXT

Comprehensive discharge planning by advanced practice nurses has demonstrated short-term reductions in readmissions of elderly patients, but the benefits of more intensive follow-up of hospitalized elders at risk for poor outcomes after discharge has not been studied.

OBJECTIVE

To examine the effectiveness of an advanced practice nurse-centered discharge planning and home follow-up intervention for elders at risk for hospital readmissions.

DESIGN

Randomized clinical trial with follow-up at 2, 6, 12, and 24 weeks after index hospital discharge.

SETTING

Two urban, academically affiliated hospitals in Philadelphia, Pa.

PARTICIPANTS

Eligible patients were 65 years or older, hospitalized between August 1992 and March 1996, and had 1 of several medical and surgical reasons for admission.

INTERVENTION

Intervention group patients received a comprehensive discharge planning and home follow-up protocol designed specifically for elders at risk for poor outcomes after discharge and implemented by advanced practice nurses.

MAIN OUTCOME MEASURES

Readmissions, time to first readmission, acute care visits after discharge, costs, functional status, depression, and patient satisfaction.

RESULTS

A total of 363 patients (186 in the control group and 177 in the intervention group) were enrolled in the study; 70% of intervention and 74% of control subjects completed the trial. Mean age of sample was 75 years; 50% were men and 45% were black. By week 24 after the index hospital discharge, control group patients were more likely than intervention group patients to be readmitted at least once (37.1 % vs 20.3 %; P<.001). Fewer intervention group patients had multiple readmissions (6.2% vs 14.5%; P = .01) and the intervention group had fewer hospital days per patient (1.53 vs 4.09 days; P<.001). Time to first readmission was increased in the intervention group (P<.001). At 24 weeks after discharge, total Medicare reimbursements for health services were about $1.2 million in the control group vs about $0.6 million in the intervention group (P<.001). There were no significant group differences in post-discharge acute care visits, functional status, depression, or patient satisfaction.

CONCLUSIONS

An advanced practice nurse-centered discharge planning and home care intervention for at-risk hospitalized elders reduced readmissions, lengthened the time between discharge and readmission, and decreased the costs of providing health care. Thus, the intervention demonstrated great potential in promoting positive outcomes for hospitalized elders at high risk for rehospitalization while reducing costs.

Race differences in the age at diagnosis among medicaid-eligible children with autism

OBJECTIVE

To examine racial differences in the age at which Medicaid-eligible children first receive an autistic disorder (AD) diagnosis and to examine time in mental health treatment until an AD diagnosis was received.

METHOD

Philadelphia Medicaid specialty mental health claims identified 406 children who received services in 1999 for AD. Claims from 1993-1999 were used to identify the date of first mental health visit, first receipt of AD diagnosis, and number of visits occurring between those dates. Linear regression was used to examine the relationship among race, age at first diagnosis of AD, time in mental health treatment, and number of visits until the diagnosis was made.

RESULTS

On average, white children received the AD diagnosis at 6.3 years of age, compared with 7.9 years for black children (p <.001). White children entered the mental health system at an earlier age (6.0 versus 7.1 years, p =.005); however, after adjusting for age, sex, and time eligible for Medicaid, black children required more time in treatment before receiving the diagnosis.

CONCLUSIONS

Important disparities exist in the early detection and treatment of autism. These disparities may be the result of differences in help-seeking, advocacy and support, and clinician behaviors.

Comparison of the PTSD Symptom Scale-Interview Version and the Clinician-Administered PTSD scale

The Clinician-Administered PTSD Scale (CAPS) is one of the most frequently used measures of posttraumatic stress disorder (PTSD). It has been shown to be a reliable and valid measure, although its psychometric properties in nonveteran populations are not well known. One problem with the CAPS is its long assessment time. The PTSD Symptom Scale--Interview Version (PSS-I) is an alternative measure of PTSD severity, requiring less assessment time than the CAPS. Preliminary studies indicate that the PSS-I is reliable and valid in civilian trauma survivors. In the present study we compared the psychometric properties of the CAPS and the PSS-I in a sample of 64 civilian trauma survivors with and without PTSD. Participants were administered the CAPS, the PSS-I, and the Structured Clinical Interview for DSM-IV (SCID) by separate interviewers, and their responses were videotaped and rated by independent clinicians. Results indicated that the CAPS and the PSS-I showed high internal consistency, with no differences between the two measures. Interrater reliability was also high for both measures, with the PSS-I yielding a slightly higher coefficient. The CAPS and the PSS-I correlated strongly with each other and with the SCID. Although the CAPS had slightly higher specificity and the PSS-I had slightly higher sensitivity to PTSD, overall the CAPS and the PSS-I performed about equally well. These results suggest that the PSS-I can be used instead of the CAPS in the assessment of PTSD, thus decreasing assessment time without sacrificing reliability or validity.

Racial differences in the use of BRCA1/2 testing among women with a family history of breast or ovarian cancer

CONTEXT

Given the current context of racial disparities in health and health care and the historical context of eugenics, racial disparities in the use of genetic susceptibility testing have been widely anticipated. However, to our knowledge there are no published studies examining the magnitude and determinants of racial differences in the use of genetic susceptibility testing.

OBJECTIVES

To investigate the relationship between race and the use of BRCA1/2 counseling among women with a family history of breast or ovarian cancer and to determine the contribution of socioeconomic characteristics, cancer risk perception and worry, attitudes about genetic testing, and interactions with primary care physicians to racial differences in utilization.

DESIGN, SETTING, AND PARTICIPANTS

Case-control study (December 1999-August 2003) of 408 women with a family history of breast or ovarian cancer, of whom 217 underwent genetic counseling for BRCA1/2 testing (cases) and 191 women did not (controls). Participants received primary care within a large health system in greater Philadelphia, Pa.

MAIN OUTCOME MEASURES

Probability of carrying a BRCA1/2 mutation, socioeconomic characteristics, perception of breast and ovarian cancer risk, worry about breast and ovarian cancer, attitudes about BRCA1/2 testing, and primary care physician discussion of BRCA1/2 testing were measured prior to undergoing BRCA1/2 counseling for cases and at the time of enrollment for controls.

RESULTS

African American women with a family history of breast or ovarian cancer were significantly less likely to undergo genetic counseling for BRCA1/2 testing than were white women with a family history of breast or ovarian cancer (odds ratio, 0.22; 95% confidence interval, 0.12-0.40). This association persisted after adjustment for probability of BRCA1/2 mutation, socioeconomic characteristics, breast and ovarian cancer risk perception and worry, attitudes about the risks and benefits of BRCA1/2 testing, and primary care physician discussion of BRCA1/2 testing (adjusted odds ratio for African American vs white, 0.28; 95% confidence interval, 0.09-0.89).

CONCLUSIONS

Racial disparities in the use of BRCA1/2 counseling are large and do not appear to be explained by differences in risk factors for carrying a BRCA1/2 mutation, socioeconomic factors, risk perception, attitudes, or primary care physician recommendations. The benefit of predictive genetic testing will not be fully realized unless these disparities can be addressed.

Increased mortality in Philadelphia associated with daily air pollution concentrations

Cause-specific deaths by day for the years 1973 to 1980 in Philadelphia, Pennsylvania, were extracted from National Center for Health Statistics mortality tapes. Death from accidents (International Classification of Disease, Revision 9 greater than or equal to 800) and deaths outside of the city were excluded. Daily counts of deaths were regressed using Poisson regression on total suspended particulate (TSP) and/or SO2 on the same day and on the preceding day, controlling for year, season, temperature, and humidity. A significant positive association was found between total mortality (mean of 48 deaths/day) and both TSP (second highest daily mean, 222 micrograms/m3) and SO2 (second highest daily mean, 299 micrograms/m3). The strongest associations were found with the mean pollution of the current and the preceding days. Total mortality was estimated to increase by 7% (95% CI, 4 to 10%) with each 100-micrograms/m3 increase in TSP, and 5% (95% CI, 3 to 7%) with each 100-micrograms/m3 increase in SO2. When both pollutants were considered simultaneously, the SO2 association was no longer significant. Mortality increased monotonically with TSP. The effect of 100 micrograms/m3 TSP was stronger in subjects older than 65 yr of age (10% increase) compared with those younger than 65 yr of age (3% increase). Cause-specific mortality was also associated with a 100-micrograms/m3 increase in TSP: chronic obstructive pulmonary disease (ICD9 490-496), +19% (95% CI, 0 to 42%), pneumonia (ICD9 480-486 & 507), +11% (95% CI, -3 to +27%), and cardiovascular disease (ICD9 390-448), +10% (95% CI, 6 to 14%). These results are somewhat higher than previously reported associations, and they add to the body of evidence showing that particulate pollution is associated with increased daily mortality at current levels in the United States.

"Every 'never' I ever said came true": transitions from opioid pills to heroin injecting

This qualitative study documents the pathways to injecting heroin by users in Philadelphia and San Francisco before and during a pharmaceutical opioid pill epidemic. Data was collected through in-depth, semi-structured interviews (conducted between 2010 and 2012) that were, conducted against a background of longer-term participant-observation, ethnographic studies of street-based drug users and dealers in Philadelphia (2007-12) and San Francisco (1994-2007, 2012). Philadelphia and San Francisco were selected for their contrasting political economies, immigration patterns and source type of heroin. In Philadelphia the ethnographers found heroin injectors, usually white users, who had started their opiate using careers with prescription opioids rather than transitioning from other drugs. In both Philadelphia and San Francisco, most of the young heroin injectors interviewed began, their drug-use trajectories with opioid pills--usually Percocet (oxycodone and acetaminophen), generic short acting oxycodone or, OxyContin (long-acting oxycodone)--before transitioning to heroin, usually by nasal inhalation (sniffing) or smoking at first, followed by injecting. While most of the Philadelphia users were born in the city or its suburbs and had started using both opioid pills and heroin there, many of the San Francisco users had initiated their pill and sometimes heroin use elsewhere and had migrated to the city from around the country. Nevertheless, patterns of transition of younger injectors were similar in both cities suggesting an evolving national pattern. In contrast, older users in both Philadelphia and San Francisco were more likely to have graduated to heroin injection from non-opiate drugs such as cannabis, methamphetamine and cocaine. Pharmaceutical opioid initiates typically reported switching to heroin for reasons of cost and ease-of-access to supply after becoming physically and emotionally dependent on opioid pills. Many expressed surprise and dismay at their progression to sniffing and subsequently to injecting heroin. Historically and structurally these users found themselves caught at the intersection of two major developments in the opiate supply: (1) an over 500% increase in opiate pill prescription from 1997 to 2005 resulting in easy access to diverted supplies of less stigmatized opiates than heroin and (2) a heroin supply glut, following the US entry of Colombian-sourced, heroin in the early 1990s, that decreased cost and increased purity at the retail level. A nationwide up-cycle of heroin use may be occurring among young inner city, suburban and rural youth fueled by widespread prescription opioid pill use.

Childhood illness-related parenting stress: the pediatric inventory for parents

OBJECTIVE

To develop a measure of parenting stress related to caring for a child with an illness and to evaluate its psychometric properties with a group of parents of children with cancer.

METHODS

One hundred twenty-six parents (105 mothers, 21 fathers) of children (65 boys and 61 girls, M: age: 12.75 years) being followed by an oncology service were assessed using the 42-item self-report Pediatric Inventory for Parents (PIP). Internal consistency was assessed and construct validity was investigated with standardized, general self-report measures of anxiety and parenting stress.

RESULTS

Internal consistency reliability for the PIP was high (Cronbach alpha range:80-.96). PIP scores were significantly correlated with a measure of state anxiety and also with parenting stress, demonstrating construct validity. After we controlled for demographic variables and general parenting stress, PIP scores showed strong independent associations with state anxiety.

CONCLUSIONS

Preliminary data indicate that the PIP is a reliable and valid tool to assess parenting stress in pediatric oncology populations. As a measure of illness-related parenting stress, the PIP may be used to provide information about parent well-being that extends beyond that obtained from general measures.

Common variation in KITLG and at 5q31.3 predisposes to testicular germ cell cancer

Testicular germ cell tumors (TGCT) have been expected to have a strong underlying genetic component. We conducted a genome-wide scan among 277 TGCT cases and 919 controls and found that seven markers at 12p22 within KITLG (c-KIT ligand) reached genome-wide significance (P < 5.0 x 10(-8) in discovery). In independent replication, TGCT risk was increased threefold per copy of the major allele at rs3782179 and rs4474514 (OR = 3.08, 95% CI = 2.29-4.13; OR = 3.07, 95% CI = 2.29-4.13, respectively). We found associations with rs4324715 and rs6897876 at 5q31.3 near SPRY4 (sprouty 4; P < 5.0 x 10(-6) in discovery). In independent replication, risk of TGCT was increased nearly 40% per copy of the major allele (OR = 1.37, 95% CI = 1.14-1.64; OR = 1.39, 95% CI = 1.16-1.66, respectively). All of the genotypes were associated with both seminoma and nonseminoma TGCT subtypes. These results demonstrate that common genetic variants affect TGCT risk and implicate KITLG and SPRY4 as genes involved in TGCT susceptibility.

New neighborhood grocery store increased awareness of food access but did not alter dietary habits or obesity

National and local policies to improve diet in low-income US populations include increasing physical access to grocery stores and supermarkets in underserved neighborhoods. In a pilot study that evaluated the impacts of opening a new supermarket in a Philadelphia community considered a "food desert"-part of the Pennsylvania Fresh Food Financing Initiative-we found that the intervention moderately improved residents' perceptions of food accessibility. However, it did not lead to changes in reported fruit and vegetable intake or body mass index. The effectiveness of interventions to improve physical access to food and reduce obesity by encouraging supermarkets to locate in underserved areas therefore remains unclear. Nevertheless, the present findings suggest that simply improving a community's retail food infrastructure may not produce desired changes in food purchasing and consumption patterns. Complementary policy changes and interventions may be needed to help consumers bridge the gap between perception and action. The replication of our findings in other settings and research into the factors that influence community residents' receptivity to improved food access are urgently required.

Artificial Intelligence Augmentation of Radiologist Performance in Distinguishing COVID-19 from Pneumonia of Other Origin at Chest CT

Background Coronavirus disease 2019 (COVID-19) and pneumonia of other diseases share similar CT characteristics, which contributes to the challenges in differentiating them with high accuracy. Purpose To establish and evaluate an artificial intelligence (AI) system for differentiating COVID-19 and other pneumonia at chest CT and assessing radiologist performance without and with AI assistance. Materials and Methods A total of 521 patients with positive reverse transcription polymerase chain reaction results for COVID-19 and abnormal chest CT findings were retrospectively identified from 10 hospitals from January 2020 to April 2020. A total of 665 patients with non-COVID-19 pneumonia and definite evidence of pneumonia at chest CT were retrospectively selected from three hospitals between 2017 and 2019. To classify COVID-19 versus other pneumonia for each patient, abnormal CT slices were input into the EfficientNet B4 deep neural network architecture after lung segmentation, followed by a two-layer fully connected neural network to pool slices together. The final cohort of 1186 patients (132 583 CT slices) was divided into training, validation, and test sets in a 7:2:1 and equal ratio. Independent testing was performed by evaluating model performance in separate hospitals. Studies were blindly reviewed by six radiologists without and then with AI assistance. Results The final model achieved a test accuracy of 96% (95% confidence interval [CI]: 90%, 98%), a sensitivity of 95% (95% CI: 83%, 100%), and a specificity of 96% (95% CI: 88%, 99%) with area under the receiver operating characteristic curve of 0.95 and area under the precision-recall curve of 0.90. On independent testing, this model achieved an accuracy of 87% (95% CI: 82%, 90%), a sensitivity of 89% (95% CI: 81%, 94%), and a specificity of 86% (95% CI: 80%, 90%) with area under the receiver operating characteristic curve of 0.90 and area under the precision-recall curve of 0.87. Assisted by the probabilities of the model, the radiologists achieved a higher average test accuracy (90% vs 85%, Δ = 5, P < .001), sensitivity (88% vs 79%, Δ = 9, P < .001), and specificity (91% vs 88%, Δ = 3, P = .001). Conclusion Artificial intelligence assistance improved radiologists' performance in distinguishing coronavirus disease 2019 pneumonia from non-coronavirus disease 2019 pneumonia at chest CT. © RSNA, 2020 Online supplemental material is available for this article.

Reducing the Influence of Anecdotal Reasoning on People’s Health Care Decisions: Is a Picture Worth a Thousand Statistics?

Background. People’s treatment decisions are often influenced by anecdotal rather than statistical information. This can lead to patients making decisions based on others’ experiences rather than on evidence-based medicine. Objective. To test whether the use of a quiz or pictograph decreases people’s reliance on anecdotal information. Design. Two cross-sectional survey studies using hypothetical scenarios. Participants read a scenario describing angina and indicated a preference for either bypass surgery or balloon angioplasty. The cure rate of both treatments was presented using prose, a pictograph, a quiz, or a pictograph and quiz combination. Participants read anecdotes from hypothetical patients who described the outcome of their treatment; the number of successful anecdotes was either representative or unrepresentative of the cure rates. Setting and Participants. Prospective jurors at the Philadelphia County Courthouse and travelers at the Detroit-Wayne County Metropolitan Airport. Measurements. Proportion of respondents preferring bypass over balloon angioplasty. Results. In study 1, when statistical information was presented in prose, treatment choices were influenced by anecdotes, with 41% of participants choosing bypass when the anecdotes were representative and only 20% choosing it when the anecdotes were unrepresentative (x2 = 14.40, P < 0.001). When statistics were reinforced with the pictograph and quiz, anecdotes had no significant influence on treatment decisions (38% choosing bypass when anecdotes were representative v. 44% when unrepresentative, x2 = 1.08, P > 0.20). In study 2, the tradeoff quiz did not reduce the impact of the anecdotes (27% v. 28% choosing bypass after receiving or not receiving the quiz, x2 < 1, P > 0.20). However, the pictograph significantly reduced the impact of anecdotes, with 27% choosing bypass after receiving no pictograph and 40% choosing bypass after receiving a pictograph (x2 = 6.44, P < 0.001). Conclusions. Presenting statistical information using a pictograph can reduce the undue influence of anecdotal reasoning on treatment choices.

The role of mother-daughter sexual risk communication in reducing sexual risk behaviors among urban adolescent females: a prospective study

PURPOSE

To prospectively examine the relationship between mother-daughter communication about sex and selected sexual risk behaviors among inner-city adolescent females.

METHODS

Participants were 219 sexually experienced females, 12 to 19 years of age, recruited from an inner-city adolescent medicine clinic in Philadelphia, PA, and randomly assigned to the control group of an HIV-risk reduction intervention study. Analyses were limited to data from control group participants to avoid confounding intervention effects. Poisson regression was employed to model three self-reported sexual risk behaviors: number of male sexual partners, number of episodes of sexual intercourse, and number of episodes of unprotected intercourse. Mediation effects were evaluated using variables from the Theory of Planned Behavior. Data were analyzed using Poisson regression.

RESULTS

Higher levels of mother-daughter sexual risk communication were associated with fewer episodes of sexual intercourse and unprotected intercourse at 3-month follow-up. There was evidence that the relationship of communication to unprotected intercourse was mediated by condom use self-efficacy. Mother-daughter sexual risk communication was not significantly associated with adolescents' reports of numbers of male sexual partner.

CONCLUSIONS

This prospective study supports the notion that mothers who communicate with their daughters about sex can affect their daughters' sexual behaviors in positive ways. These findings lend support for the design and implementation of family-based approaches to improve parent-adolescent sexual risk communication as one means of reducing HIV-related sexual risk behaviors among inner-city adolescent females.

Anatomic features of enhancing renal masses predict malignant and high-grade pathology: a preoperative nomogram using the RENAL Nephrometry score

BACKGROUND

Counseling patients with enhancing renal mass currently occurs in the context of significant uncertainty regarding tumor pathology.

OBJECTIVE

We evaluated whether radiographic features of renal masses could predict tumor pathology and developed a comprehensive nomogram to quantitate the likelihood of malignancy and high-grade pathology based on these features.

DESIGN, SETTING, AND PARTICIPANTS

We retrospectively queried Fox Chase Cancer Center's prospectively maintained database for consecutive renal masses where a Nephrometry score was available.

INTERVENTION

All patients in the cohort underwent either partial or radical nephrectomy.

MEASUREMENTS

The individual components of Nephrometry were compared with histology and grade of resected tumors. We used multiple logistic regression to develop nomograms predicting the malignancy of tumors and likelihood of high-grade disease among malignant tumors.

RESULTS AND LIMITATIONS

Nephrometry score was available for 525 of 1750 renal masses. Nephrometry score correlated with both tumor grade (p < 0.0001) and histology (p < 0.0001), such that small endophytic nonhilar tumors were more likely to represent benign pathology. Conversely, large interpolar and hilar tumors more often represented high-grade cancers. The resulting nomogram from these data offers a useful tool for the preoperative prediction of tumor histology (area under the curve [AUC]: 0.76) and grade (AUC: 0.73). The model was subjected to out-of-sample cross-validation; however, lack of external validation is a limitation of the study.

CONCLUSIONS

The current study is the first to objectify the relationship between tumor anatomy and pathology. Using the Nephrometry score, we developed a tool to quantitate the preoperative likelihood of malignant and high-grade pathology of an enhancing renal mass.

Differences in the patterns of health care system distrust between blacks and whites

CONTEXT

Although health care-related distrust may contribute to racial disparities in health and health care in the US, current evidence about racial differences in distrust is often conflicting, largely limited to measures of physician trust, and rarely linked to multidimensional trust or distrust.

OBJECTIVE

To test the hypothesis that racial differences in health care system distrust are more closely linked to values distrust than to competence distrust.

DESIGN

Cross-sectional telephone survey.

PARTICIPANTS

Two hundred fifty-five individuals (144 black, 92 white) who had been treated in primary care practices or the emergency department of a large, urban Mid-Atlantic health system.

PRIMARY MEASURES

Race, scores on the overall health care system distrust scale and on the 2 distrust subscales, values distrust and competence distrust.

RESULTS

In univariate analysis, overall health care system distrust scores were slightly higher among blacks than whites (25.8 vs 24.1, p = .05); however, this difference was driven by racial differences in values distrust scores (15.4 vs 13.8, p = .003) rather than in competence distrust scores (10.4 vs 10.3, p = .85). After adjustment for socioeconomic status, health/psychological status, and health care access, individuals in the top quartile of values distrust were significantly more likely to be black (odds ratio = 2.60, 95% confidence interval = 1.03-6.58), but there was no significant association between race and competence distrust.

CONCLUSIONS

Racial differences in health care system distrust are complex with far greater differences seen in the domain of values distrust than in competence distrust. This framework may be useful for explaining the mixed results of studies of race and health care-related distrust to date, for the design of future studies exploring the causes of racial disparities in health and health care, and for the development and testing of novel strategies for reducing these disparities.

Effect of Greening Vacant Land on Mental Health of Community-Dwelling Adults: A Cluster Randomized Trial

IMPORTANCE

Neighborhood physical conditions have been associated with mental illness and may partially explain persistent socioeconomic disparities in the prevalence of poor mental health.

OBJECTIVE

To evaluate whether interventions to green vacant urban land can improve self-reported mental health.

DESIGN, SETTING, AND PARTICIPANTS

This citywide cluster randomized trial examined 442 community-dwelling sampled adults living in Philadelphia, Pennsylvania, within 110 vacant lot clusters randomly assigned to 3 study groups. Participants were followed up for 18 months preintervention and postintervention. This trial was conducted from October 1, 2011, to November 30, 2014. Data were analyzed from July 1, 2015, to April 16, 2017.

INTERVENTIONS

The greening intervention involved removing trash, grading the land, planting new grass and a small number of trees, installing a low wooden perimeter fence, and performing regular monthly maintenance. The trash cleanup intervention involved removal of trash, limited grass mowing where possible, and regular monthly maintenance. The control group received no intervention.

MAIN OUTCOMES AND MEASURES

Self-reported mental health measured by the Kessler-6 Psychological Distress Scale and the components of this scale.

RESULTS

A total of 110 clusters containing 541 vacant lots were enrolled in the trial and randomly allocated to the following 1 of 3 study groups: the greening intervention (37 clusters [33.6%]), the trash cleanup intervention (36 clusters [32.7%]), or no intervention (37 clusters [33.6%]). Of the 442 participants, the mean (SD) age was 44.6 (15.1) years, 264 (59.7%) were female, and 194 (43.9%) had a family income less than $25 000. A total of 342 participants (77.4%) had follow-up data and were included in the analysis. Of these, 117 (34.2%) received the greening intervention, 107 (31.3%) the trash cleanup intervention, and 118 (34.5%) no intervention. Intention-to-treat analysis of the greening intervention compared with no intervention demonstrated a significant decrease in participants who were feeling depressed (-41.5%; 95% CI, -63.6% to -5.9%; P = .03) and worthless (-50.9%; 95% CI, -74.7% to -4.7%; P = .04), as well as a nonsignificant reduction in overall self-reported poor mental health (-62.8%; 95% CI, -86.2% to 0.4%; P = .051). For participants living in neighborhoods below the poverty line, the greening intervention demonstrated a significant decrease in feeling depressed (-68.7%; 95% CI, -86.5% to -27.5%; P = .007). Intention-to-treat analysis of those living near the trash cleanup intervention compared with no intervention showed no significant changes in self-reported poor mental health.

CONCLUSIONS AND RELEVANCE

Among community-dwelling adults, self-reported feelings of depression and worthlessness were significantly decreased, and self-reported poor mental health was nonsignificantly reduced for those living near greened vacant land. The treatment of blighted physical environments, particularly in resource-limited urban settings, can be an important treatment for mental health problems alongside other patient-level treatments.

A randomized, controlled trial of mindfulness-based art therapy (MBAT) for women with cancer

The purpose of this study was to gather data on the efficacy of a newly developed psychosocial group intervention for cancer patients, called mindfulness-based art therapy (MBAT). One hundred and eleven women with a variety of cancer diagnoses were paired by age and randomized to either an eight-week MBAT intervention group or a wait-list control group. Ninety-three participants (84%) completed both the pre- and post-study measurements. As compared to the control group, the MBAT group demonstrated a significant decrease in symptoms of distress (as measured by the Symptoms Checklist-90-Revised) and significant improvements in key aspects of health-related quality of life (as measured by the Medical Outcomes Study Short-Form Health Survey). This investigation of MBAT provides initial encouraging data that support a possible future role for the intervention as a psychosocial treatment option for cancer patients.

Assessing pediatric senior residents' training in resuscitation: fund of knowledge, technical skills, and perception of confidence

OBJECTIVE

To describe pediatric housestaff knowledge, experience, confidence in pediatric resuscitations and their ability to perform important resuscitation procedures during the usual training experience.

DESIGN AND PARTICIPANTS

Cohort study of PGY-3 level residents in a ACGME accredited pediatric residency training program at a large, tertiary care children's hospital.

METHODS

Fund of knowledge was assessed by administering the standardized test from the Pediatric Advanced Life Support (PALS) Course in addition to a supplemental short answer test requiring clinical problem-solving skills. Procedural skills were evaluated through observation of the resident performing four procedures during a skills workshop using a weighted step-wise grading sheet. Resident experience and confidence was quantified using an anonymous survey.

RESULTS

Ninety-seven percent of residents participated. Residents achieved high scores on the standardized PALS test (93.2%+/-5.5), but performed less well when answering more complicated questions (60.0%+/-9.9) on the short answer test. No resident was able to successfully perform both basic and advanced airway skills, and only 11% successfully completed both vascular skills. Although residents were overall confident in their resuscitation skills, performance in the skill workshop revealed significant deficits. For example, only 18% performed ancillary airway maneuvers properly. None of the residents performed all four skills correctly. Experience in both real and mock resuscitations was infrequent. Residents reported receiving feedback on their performance less than half of the time. Over 89% of them felt that resuscitation knowledge and skill were important for their future chosen career.

CONCLUSION

Pediatric residents infrequently lead or participate in real or mock resuscitations. Although confident in performing many of the necessary resuscitation skills, few residents performed critical components of these skills correctly. Current pediatric residency training may not provide sufficient experience to develop adequate skills, fund of knowledge, or confidence needed for resuscitation.

HIV/STD risk reduction interventions for African American and Latino adolescent girls at an adolescent medicine clinic: a randomized controlled trial

BACKGROUND

Adolescent girls in the United States and around the world are at a heightened risk for sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV).

OBJECTIVE

To determine the efficacy of a skill-based HIV/STD risk-reduction intervention in reducing self-reported unprotected sexual intercourse among African American and Latino adolescent girls.

DESIGN

Randomized controlled trial with 3-, 6-, and 12-month follow-ups.

SETTING AND PARTICIPANTS

Sexually experienced African American and Latino adolescent girls recruited from the adolescent medicine clinic of a children's hospital serving a low-income inner-city community (N = 682, mean age, 15.5 years); 88.6% were retained at the 12-month follow-up.

INTERVENTIONS

Three 250-minute interventions based on cognitive-behavioral theories and elicitation research: an information-based HIV/STD intervention provided information necessary to practice safer sex; a skill-based HIV/STD intervention provided information and taught skills necessary to practice safer sex; or a health-promotion control intervention concerned with health issues unrelated to sexual behavior.

MAIN OUTCOME MEASURES

Primary outcome measure was self-reported frequency of unprotected sexual intercourse; secondary outcomes included the frequency of sexual intercourse while intoxicated, the number of sexual partners, biologically confirmed STDs, and theoretical mediator variables, including the intention to use condoms, beliefs about using condoms, and condom-use knowledge.

RESULTS

No differences between the information intervention and the health control intervention were statistically significant. Skills-intervention participants (mean [SE], 2.27 [0.81]) reported less unprotected sexual intercourse at the 12-month follow-up than did information-intervention participants (mean [SE], 4.04 [0.80]; P = .03), or health control-intervention participants (mean [SE], 5.05 [0.81]; P = .002). At the 12-month follow-up, skills-intervention participants (mean [SE], 0.91 [0.05]) reported fewer sexual partners (P = .04) compared with health control-intervention participants (mean [SE], 1.04 [0.05]) and were less likely to test positive for STD (mean [SE], 10.5% [2.9%]) than were health control-intervention participants (mean [SE], 18.2% [2.8%]; P = .05). No differences in the frequency of unprotected sexual intercourse, the number of partners, or the rate of STD were observed at the 3- or 6-month follow-up between skill-intervention participants and information-intervention or health control-intervention participants.

CONCLUSION

Skill-based HIV/STD interventions can reduce sexual risk behaviors and STD rate among African American and Latino adolescent girls in clinic settings.

Placement stability and mental health costs for children in foster care

OBJECTIVE

Although prior population-based studies have found that children in foster care use more mental health services than their Medicaid peers, less is known about how different experiences in foster care impact the likelihood of mental health service use. The primary aim of this study is to test the hypothesis that instability of foster care placements is associated with higher costs for mental health care services. The secondary aim is to test the hypothesis that foster care children are also more likely to generate high costs for mental health services if they generate higher costs for non-mental health claims.

METHODS

Using administrative child welfare data linked to Medicaid claims, we assembled a unique retrospective cohort of adjudicated dependent children >2 years old who entered foster care between July 1993 and June 1995, spent at least 9 months in care, and were Medicaid eligible during a 1-year follow-up period. The primary outcome was high mental health service use, defined as having costs in the top decile of the sample. The primary independent variables were the number of foster care placements during the year and whether placements were interrupted by a return home for at least 1 month during that year (episodic foster care). We used logistic regression to estimate the association between placements and service utilization, with adjustment for age and physical health care costs.

RESULTS

Of the 1635 children in the study, 41% had > or = 3 foster care placements, and 5% had episodic foster care during the year of observation. The top 10% of mental health service users accounted for 83% of the 2.4 million dollars in mental health costs. Both multiple placements and episodic foster care increased the predicted probability of high mental health service use. Higher physical health care costs also increased the probability of high mental health use for all children, but this increased probability was most dramatic among children with episodic foster care (probability of high mental health use: 0.78; 95% confidence interval: 0.42-0.94).

CONCLUSIONS

Foster care placement instability was associated with increased mental health costs during the first year in foster care, particularly among children with increasing general health care costs. These findings highlight the importance of interventions that address the global health of children in foster care and may permit better targeting of health care resources to subgroups of children most likely to use services.

Effects of the home environmental skill-building program on the caregiver-care recipient dyad: 6-month outcomes from the Philadelphia REACH Initiative

PURPOSE

We examine 6-month effects of the Environmental Skill-Building Program on caregiver well-being and care recipient functioning and whether effects vary by caregiver gender, race (White or non-White), and relationship (spouse or nonspouse).

DESIGN AND METHODS

We enrolled 255 family caregivers of community-residing persons with Alzheimer's disease or related disorders, of whom 190 participated in a follow-up interview. Caregivers were randomized to a usual care control group or intervention group that received five home contacts and one telephone contact by occupational therapists, who provided education, problem-solving training, and adaptive equipment. Baseline and 6-month follow-up included self-report measures of caregiver objective and subjective burden, caregiver well-being, and care recipient problem behaviors and physical function.

RESULTS

Compared with controls (n = 101), intervention caregivers (n = 89) reported less upset with memory-related behaviors, less need for assistance from others, and better affect. Intervention spouses reported less upset with disruptive behaviors; men reported spending less time in daily oversight; and women reported less need for help from others, better affect, and enhanced management ability, overall well-being, and mastery relative to control group counterparts. Statistically significant treatment differences were not found for hours helping with instrumental activities of daily living, upset with providing assistance with instrumental activities of daily living and activities of daily living, perceived change in somatic symptoms, White versus non-White caregivers, or care recipient outcomes.

IMPLICATIONS

The Environmental Skill-Building Program reduces burden and enhances caregiver well-being in select domains and has added benefit for women and spouses.

Effects of Methylphenidate on Attention Deficits After Traumatic Brain Injury

OBJECTIVE

To evaluate the effects of methylphenidate on a variety of aspects of attention, ranging from laboratory-based impairment measures to caregiver ratings and work productivity, in individuals after traumatic brain injury.

DESIGN

A total of 34 adults with moderate to severe traumatic brain injury and attention complaints in the postacute phase of recovery were enrolled in a 6-wk, double-blind, placebo-controlled, repeated crossover study of methylphenidate, administered in a dose of 0.3 mg/kg/dose, twice a day. A wide range of attentional measures was gathered weekly, including computerized and paper-and-pencil tests of attention, videotaped records of individual work in a distracting environment, real-time observational scoring of attentiveness in a classroom environment, and caregiver and clinician rating scales of attentiveness. Participants also attempted to guess their drug condition each week. Data from the first ten participants were used for pilot purposes, to develop attentional factors for composite scoring, and to identify attentional dimensions suggestive of a treatment effect for independent replication. The remaining 24 participants' results were used to confirm potential treatment effects seen in the pilot sample, using Wilcoxon's signed-ranks test on composite factor scores and individual variables.

RESULTS

A total of 54 dependent variables were reduced to 13 composite factors and 13 remaining individual variables. Of the 13 attentional factors, five showed suggestive treatment effects in the pilot sample. Of these, three showed statistically significant treatment effects in the replication sample: speed of information processing (effect sizes, -0.06 to 0.48; P < 0.001), attentiveness during individual work tasks (effect sizes, 0.15-0.62; P = 0.01), and caregiver ratings of attention (effect sizes, 0.44-0.50; P = 0.01). Of the individual variables, four showed suggestive treatment effects in the pilot sample, but only one showed significant treatment effects in the replication sample: reaction time before errors in the Sustained Attention to Response Task (effect size, 0.20; P = 0.03). No treatment-related improvement was seen in divided attention, sustained attention, or susceptibility to distraction. None of the variables showed suggestive or definite negative treatment effects. Effect sizes for those performance measures positively affected by methylphenidate were in the small to medium range and included both impairment and activity level measures. Improvements in processing speed did not seem to come at the expense of accuracy.

CONCLUSIONS

Methylphenidate, at 0.3 mg/kg/dose, given twice a day to individuals with attentional complaints after traumatic brain injury, seems to have clinically significant positive effects on speed of processing, caregiver ratings of attention, and some aspects of on-task behavior in naturalistic tasks. Further research is needed to identify the optimal dose and to extend these findings to less carefully selected individuals.

Noninferiority of functional outcome in ambulatory management of obstructive sleep apnea

RATIONALE

Home portable monitor testing is increasingly being used to diagnose patients with obstructive sleep apnea (OSA) and to initiate them on continuous positive airway pressure (CPAP) treatment.

OBJECTIVES

To compare functional outcome and treatment adherence in patients who receive ambulatory versus in-laboratory testing for OSA.

METHODS

Veterans with suspected OSA were randomized to either home testing or standard in-laboratory testing. Home testing consisted of a type 3 portable monitor recording followed by at least three nights using an automatically adjusting positive airway pressure apparatus. Participants diagnosed with OSA were treated with CPAP for 3 months.

MEASUREMENTS AND MAIN RESULTS

We measured the change in Functional Outcomes of Sleep Questionnaire score, with an a priori noninferiority delta of -1, and the mean daily hours of objectively measured CPAP adherence, with an a priori noninferiority delta of -0.75 hour/day. Of the 296 subjects enrolled, 260 (88%) were diagnosed with OSA, and 213 (75%) were initiated on CPAP. Mean ± SD functional outcome score improved 1.74 ± 2.81 in the home group (P < 0.001) and 1.85 ± 2.46 in the in-laboratory group (P < 0.0001). The lower bound of the one-sided 95% noninferiority confidence interval was -0.54. Mean ± SD hours of daily CPAP adherence were 3.5 ± 2.5 hours/day in the home group and 2.9 ± 2.3 hours/day in the in-laboratory group (P = 0.08). The lower bound of the one-sided 95% noninferiority confidence interval was 0.03.

CONCLUSIONS

Functional outcome and treatment adherence in patients evaluated according to a home testing algorithm is not clinically inferior to that in patients receiving standard in-laboratory polysomnography.

Maternal exposure to herpes simplex virus and risk of psychosis among adult offspring

BACKGROUND

Viral exposure during gestation is thought to be a risk factor for schizophrenia. Previous studies have indicated that prenatal exposure to herpes simplex virus type 2 (HSV-2) may be a risk for the subsequent development of schizophrenia in some populations. In this investigation, we tested a large and diverse population to assess the risk of psychoses among offspring of mothers with serological evidence of HSV-2 infection.

METHODS

We conducted a nested case-control study of 200 adults with psychoses and 554 matched control subjects (matched for city and date of birth, race/ethnicity, gender, and parent history of treatment for mental disorder) from three cohorts of the Collaborative Perinatal Project (Boston, Providence, and Philadelphia). We analyzed stored serum samples that had been obtained from these mothers at the end of pregnancy for antibodies directed at HSV-2, using type-specific solid-phase enzyme immunoassay techniques.

RESULTS

Offspring of mothers with serologic evidence of HSV-2 infection were at significantly increased risk for the development of psychoses (odds ratio [OR] = 1.6; 95% confidence interval [CI] = 1.1-2.3). This risk was particularly elevated among women with high rates of sexual activity during pregnancy (OR = 2.6; 95% CI = 1.4-4.6).

CONCLUSIONS

Maternal exposure to herpes simplex virus type 2 is associated with an increased risk for psychoses among adult offspring. These results are consistent with a general model of risk resulting from enhanced maternal immune activation during pregnancy.
