Changes in hospitalization populations by level of complexity at children's hospitals.

It is important for hospitals to understand how hospitalizations for children are changing to adapt and best accommodate the future needs of all patient populations. This study aims to understand how hospitalizations for children with medical complexity (CMC) and non-CMC have changed over time at children's hospitals, and how hospitalizations for these children will look in the future. Children with 3+ complex chronic conditions (CCC) accounted for 7% of discharges and over one-quarter of days and one-third of costs during the study period (2012-2022). The number of CCCs was associated with increased growth in discharges, hospital days, and costs. Understanding these trends can help hospitals better allocate resources and training to prepare for pediatric patients across the spectrum of complexity.

Temporal Trends in Pediatric Acute Sinusitis Surrounding the COVID-19 Pandemic.

OBJECTIVE: We assessed patterns in the national incidence of pediatric acute sinusitis and associated complications surrounding the initial COVID-19 lockdown. STUDY DESIGN: Retrospective National Database review. SETTING: The Pediatric Health Information System. METHODS: Acute sinusitis and associated complication incidence data from 2015 to 2022 were queried. Three time periods of T1, T2, and T3 were defined as: pre-COVID-19 baseline, initial pandemic, and postpandemic. Statistical analysis included Wilcoxon rank sum tests, multivariable logistic regressions, and autoregressive integrated moving averages (ARIMA) to assess differences between the observed complication rates in T2 and T3 and the expected incidence rates in these time periods as estimated from T1 data. RESULTS: We identified 2535 acute sinusitis admissions across 42 centers. The incidence differed between T1 (31.5 cases/month), T2 (15.8 cases/month), and T3 (29 cases/month). Children aged 10 to 14 years had the highest acute sinusitis incidence rate (32.5%) compared to other ages in T2. At T1, acute sinusitis and associated complication rates followed parallel seasonal patterns. Although sinusitis incidence decreased during T2, complications increased significantly during T2 and T3 compared to T1 (37.4% and 39% vs 27.5%, P < .001). In the ARIMA model, the ratio of the observed to expected incidence (95% confidence interval) of complications was 1.09 (0.69, 2.60) in T2 and 1.14 (0.73, 2.62) in T3. CONCLUSION: We report the simultaneous decrease in acute sinusitis incidence and an increase in associated complications during and after the initial COVID-19 pandemic compared to the prepandemic baseline, reflecting changing patterns in viral infection due to the pandemic.

Comparing the Kids' Inpatient Database and National Inpatient Sample for Pediatric Research.

OBJECTIVE: Pediatric researchers use Agency for Healthcare Research and Quality (AHRQ) Kids' Inpatient Database (KID) and National Inpatient Sample (NIS) to analyze the national resource use and outcomes of hospitalized children. Inherent KID-NIS sampling design differences may yield disparate findings. We compared discharge counts and length of stay (LOS) between KID and NIS for common and rare reasons for hospitalization. METHODS: Retrospective analysis of differences in discharges counts and geometric mean LOS for children ages 0-20 years from KID and NIS in 2019, measured for normal newborns and 331 additional reasons for admission, distinguished by All-Payer Refined Diagnosis Related Groups (APR-DRG) and categorized in deciles by annual discharge volume. We followed AHRQ instructions for data clustering, stratification, and weighting to accommodate the KID and NIS designs, including random samples of 80% and 20% of pediatric discharges, respectively, per hospital. RESULTS: KID-NIS differences in national estimates for total annual discharge counts differed by only 0.5% for normal newborns and 3.7% for all other admission reasons in children. KID-NIS differences remained small aside from reasons for admission in the two lowest volume deciles: 9.5% (SD 7.9%) for admission volumes 200-520; 41.1% (SD 64.2%) for volumes <200. KID-NIS LOS differences for these two-lowest volume deciles were 7.9% (SD 7.1%) and 26.0% (SD 29.3%), respectively. CONCLUSIONS: Although KID-NIS differences in discharge counts and LOS were small for high-volume admissions, the differences increased with reasons for admission that had annual discharge volumes approximately 500 or less. For study populations with discharge counts <500, KID may be preferred, given its higher sampling of discharges per hospital.

Trauma and suicide behaviour histories among a Canadian indigenous population: an empirical exploration of the potential role of Canada's residential school system.

It has been theorized that suicide behaviours amongst indigenous peoples may be an outcome of mass trauma experienced as a result of colonization. In Canada, qualitative evidence has suggested that the Indian Residential School System set in motion a cycle of trauma, with some survivors reporting subsequent abuse, suicide, and other related behaviours. It has been further postulated that the effects of trauma can also be passed inter-generationally. Today, there are four generations of Canadian First Nations residential school survivors who may have transmitted the trauma they experienced to their own children and grandchildren. No empirical study has ever been undertaken to demonstrate this dynamic. This study is therefore the first to investigate whether a direct or indirect exposure to Canada's residential school system is associated with trauma and suicide behaviour histories. Data were collected in 2002/2003 from a representative sample of Manitoba, Canada, First Nations adults (N = 2953), including residential (N = 611) and non-residential school attendees (N = 2342). Regression analyses showed that for residential school attendees negative experiences in residential school were associated with a history of abuse, and that this history and being of younger age was associated with a history of suicide thoughts, whereas abuse history only was associated with a history of suicide attempts. For First Nations adults who did not attend a residential school, we found that age 28-44, female sex, not having a partner, and having a parent or grandparent who attended a residential school was associated with a history of abuse. This history, along with age and having had a parent or grandparent who attended residential school was associated with a history of suicide thoughts and attempts. In conclusion, this is the first study to empirically demonstrate, at the population level, the mental health impact of the residential school system on survivors and their children.

The burden of cancer risk in Canada's indigenous population: a comparative study of known risks in a Canadian region.

BACKGROUND: Canadian First Nations, the largest of the Aboriginal groups in Canada, have had lower cancer incidence and mortality rates than non-Aboriginal populations in the past. This pattern is changing with increased life expectancy, a growing population, and a poor social environment that influences risk behaviors, metabolic conditions, and disparities in screening uptake. These factors alone do not fully explain differences in cancer risk between populations, as genetic susceptibility and environmental factors also have significant influence. However, genetics and environment are difficult to modify. This study compared modifiable behavioral risk factors and metabolic-associated conditions for men and women, and cancer screening practices of women, between First Nations living on-reserve and a non-First Nations Manitoba rural population (Canada). METHODS: The study used data from the Canadian Community Health Survey and the Manitoba First Nations Regional Longitudinal Health Survey to examine smoking, binge drinking, metabolic conditions, physical activity, fruit/vegetable consumption, and cancer-screening practices. RESULTS: First Nations on-reserve had significantly higher rates of smoking (P < 0.001), binge drinking (P < 0.001), obesity (P < 0.001) and diabetes (P < 0.001), and less leisure-time physical activity (P = 0.029), and consumption of fruits and vegetables (P < 0.001). Sex differences were also apparent. In addition, First Nations women reported significantly less uptake of mammography screening (P < 0.001) but similar rates for cervical cancer screening. CONCLUSIONS: Based on the findings of this retrospective study, the future cancer burden is expected to be high in the First Nations on-reserve population. Interventions, utilizing existing and new health and social authorities, and long-term institutional partnerships, are required to combat cancer risk disparities, while governments address economic disparities.

Social isolation and loneliness: differences between older rural and urban Manitobans.

The purpose of this paper was to identify predictors of social isolation and loneliness for very old rural and urban adults. With data from the 1996 Aging in Manitoba Study (N = 1,868; age range 72-104), separate multiple regression models were constructed for rural and urban sub-samples, using the life space index (LSI) to measure social isolation as one outcome, and a loneliness index created by the authors from a combination of items to measure loneliness as a second outcome. Different factors were found to predict the outcomes for the two sub-samples. The models with isolation as the outcome produced five predictors for the rural sub-sample and three for the urban sub-sample. Only living alone was the same for both groups. The models with loneliness as the outcome produced five predictors for the rural sub-sample and two for the urban sub-sample, again with only one factor in common--four or more chronic illnesses. We conclude that health and social factors are important predictors of social isolation and loneliness, and sensitivity to these factors may improve the experience of older adults.
