Cause-Specific School Absenteeism Monitoring Identifies Community Influenza Outbreaks

ObjectiveThe Oregon Child Absenteeism due to Respiratory Disease Study (ORCHARDS) was implemented to assess the relationships between cause-specific absenteeism within a school district and medically attended influenza visits within the same community.IntroductionTransmission and amplification of influenza within schools has been purported as a driving mechanism for subsequent outbreaks in surrounding communities. However, the number of studies assessing the utility of monitoring school absenteeism as an indicator of influenza in the community is limited. ORCHARDS was initiated to evaluate the relationships between all-cause (a-Tot), illness-related (a-I), and influenza-like illness (ILI)-related absenteeism (a-ILI) within a school district and medically attended influenza A or B visits within the same community.MethodsORCHARDS was based at the Oregon School District (OSD), which enrolls 3,640 students at six schools in south-central Wisconsin. Parents reported influenza-like symptoms on an existing phone-based absenteeism reporting system. Attendance staff identified ILI using a simple case definition. Absenteeism was logged into the OSD’s existing electronic information system (Infinite Campus), and an automated process extracted counts of a-Tot, a-I, and a-ILI each school day from 9/02/14 through 6/08/17.Parents of students with acute respiratory infections (ARI) were invited to contact study staff who assessed the students’ eligibility for the study based on presence of ILI symptoms. From 1/05/15 through 6/08/17, data and nasal swabs were collected from eligible OSD students whose parents volunteered to have a study home visit within 7 days of ILI onset. Specimens were tested for influenza A and B at the Wisconsin State Laboratory of Hygiene using the CDC Human Influenza Virus Real-time RT-PCR Diagnostic Panel.For community influenza, we used data from the Wisconsin Influenza Incidence Surveillance Project (WIISP) that monitors medically attended influenza using RT-PCR at five primary care clinics surrounding the OSD.Data analysis: Over-dispersed Poisson generalized additive log-linear regression models were fit to the daily number of medically attended influenza cases and daily absenteeism counts from three sources (a-Tot, a-I, and a-ILI) with year and season (calendar day within year) as smooth functions (thin plate regression splines). Two subgroups of a-ILI representing kindergarten through 4th grade (K-4) and 5th-12th grade (5-12) were also evaluated.ResultsDuring the study period, 168,859 total absentee days (8.57% of student days), 36,104 illness days (1.83%), and 4,232 ILI days (0.21%) were recorded. Home visits were completed on 700 children [mean age = 10.0 ± 3.5 (sd) years]. Influenza RT-PCR results were available for 695 (99.3%) children: influenza A was identified in 54 (13.3%) and influenza B in 51 (12.6%) specimens. There were one large and early outbreak of influenza A (H3N2) followed by B in 2014/15, an extremely late combined outbreak of influenza A (H1N1) and B in 2015/16, and a combined outbreak of influenza A/(H3N2) and B in 2016/17. PCR detection of influenza A or B, as compared to no influenza, was strongly associated with a child with a-ILI-positive status (OR=4.74; 95% CI: 2.78-8.18; P<0.001).Nearly 2,400 medically attended ARI visits were reported during the study period. Of these, 514 patients were positive for influenza (21.5%): 371 (15.5%) influenza A and 143 (6.0%) influenza B. The temporal patterns of medically attended influenza were very similar to influenza cases in OSD students.Comparisons of the regression models demonstrated the highest correlation between absenteeism and medically attended influenza for 5th-12th grade students absent with ILI with a -1 day time lag and for all students with a-ILI with a -1 day lag (Table); a-I also had moderate correlation with a -15 day lag period.ConclusionsCause-specific absenteeism measures (a-I and a-ILI) are moderately correlated with medically attended influenza in the community and are better predictors than all-cause absenteeism. In addition, a-I preceded community influenza cases by 15 days. The monitoring system was easily implemented: a-I surveillance was fully automated and a-ILI required only minor review by attendance staff. The resulting correlations were likely lowered by the presence of other viruses that resulted in a-ILI (e.g., adenovirus) and by breaks in the school year during which absenteeism data did not accrue.Automated systems that report cause-specific absenteeism data may provide a reliable method for the early identification of influenza outbreaks in communities. From a preparedness perspective, 15-day advance warning is significant. The addition of a laboratory component could increase usefulness of the cause-specific student absenteeism monitoring as an early-warning system during influenza pandemics.

Parenting stress among child welfare involved families: Differences by child placement

The intersection of parenting stress and maltreatment underscores the importance of understanding the factors associated with parenting stress among child welfare involved families. This study takes advantage of a statewide survey of child welfare involved families to examine parent and child characteristics and concrete resources, in relation to parenting stress. Separate multivariate analyses were conducted by placement status given the difference in day-to-day parenting responsibilities for families receiving in-home supervision compared to those whose children are in out-of-home care. Across both groups, parenting stress was predicted by child mental health, a finding with critical implications for intervention to this vulnerable group of families. Parent mental health also predicted parenting stress for the in-home group and food insecurity predicted parenting stress in the out-of-home group. Findings confirm that stress varies by context and that a multi-dimensional framework, considering both psychosocial and concrete resources, is required to capture contributors to parenting stress

Effects of PMTO in Foster Families with Children with Behavior Problems: A Randomized Controlled Trial

The present randomized controlled trial examined the effectiveness of Parent Management Training Oregon for foster parents with foster children (aged 4–12) with severe externalizing behavior problems in long-term foster care arrangements. Foster children’s behavior problems are challenging for foster parents and increase the risk of placement breakdown. There is little evidence for the effectiveness of established interventions to improve child and parent functioning in foster families. The goal of Parent Management Training Oregon, a relatively long and intensive (6–9 months, with weekly sessions) parent management training, is to reduce children’s problem behavior through improvement of parenting practices. We specifically investigated whether Parent Management Training Oregon is effective to reduce foster parenting stress. A significant effect of Parent Management Training Oregon, compared to Care as Usual was expected on reduced parenting stress improved parenting practices, and on reduced child behavior problems. Multi-informant (foster mothers, foster fathers, and teachers) data were used from 86 foster families (46 Parent Management Training Oregon, 40 Care as Usual) using a pre-posttest design. Multilevel analyses based on the intention to treat principle (retention rate 73 %) showed that Parent Management Training Oregon, compared to Care as Usual, reduced general levels of parenting stress as well as child related stress and parent-related stress (small to medium effect sizes). The clinical significance of this effect was, however, limited. Compared to a decrease in the Care as Usual group, Parent Management Training Oregon helped foster mothers to maintain parental warmth (small effect size). There were no other effects of Parent Management Training Oregon on self-reported parenting behaviors. Child behavior problems were reduced in both conditions, indicating no additive effects of Parent Management Training Oregon to Care as Usual on child functioning. The potential implication of reduced foster parenting stress for placement stability is discussed
