A national study of commercial health insurance and medicaid definitions of medical necessity: what do they mean for children?

OBJECTIVE: To analyze medical necessity standards used by state Medicaid agencies and the largest commercial insurers in the United States on the basis of criteria related to scope of health problems covered and requirements for effectiveness and cost. METHODS: Information was obtained from managed care contract documents used by the 45 state Medicaid agencies enrolling children into managed care organizations and from certificates of coverage used by the largest health maintenance and preferred provider organization insurers in each state. RESULTS: Commercial insurers are more likely than Medicaid agencies to articulate medical necessity standards that limit coverage to treatment for illnesses and injuries and to include stringent requirements for cost and evidence of effectiveness. CONCLUSION: To reduce the discretion retained by insurers in determining medical necessity, particularly around the scope of health problems covered, much greater clarity and uniformity in medical necessity language will be required in the future.     

Is family history a useful tool for detecting children at risk for diabetes and cardiovascular diseases? A public health perspective

Several studies indicate that the risk for type 2 diabetes or cardiovascular disease is detectable in childhood, although these disorders may not emerge until adulthood. In addition, type 2 diabetes and cardiovascular disease seem to share risk factors, including obesity and dyslipidemia, and might even share etiology, which has important implications for screening and prevention strategies for both diseases. Primary prevention, in particular, has gained importance because the results of major randomized, controlled trials strongly suggest that, at least in high-risk adult groups, type 2 diabetes can be prevented or delayed. Furthermore, some intervention studies indicate that the risk factors for diabetes and cardiovascular disease can be reduced in children. A simple way to detect risk for either diabetes or cardiovascular disease is to examine the family history. Numerous studies have shown that adults who have 1 or more first- or second-degree relatives affected with diabetes or cardiovascular disease are at high risk of having or developing these diseases. Currently, there are no overall screening strategies recommended for either diabetes or cardiovascular disease among children and adolescents. The evidence is strong, however, that youth with a positive family history already show signs of increased risk for these conditions. Family history can be part of the approach to screening for children at risk of diabetes and cardiovascular disease and should be part of prevention campaigns aimed at reducing the burden of these diseases and their risk factors in children.     

Ambient air pollution and children��s health: A systematic review of Canadian epidemiological studies

BACKGROUND

There is growing concern about the health effects of ambient air pollution (AP) in children. The present article summarizes and compares local information regarding the adverse effects of AP on the health of Canadian children with reports from elsewhere.

METHODS

PUBMED, MEDLINE and EMBASE databases were searched for epidemiological studies, published between January 1989 and December 2004, on the adverse health effects of criteria air pollutants among Canadian children.

RESULTS

Eleven studies investigated the association between AP and various respiratory health outcomes, while one study assessed the effect of AP on sudden infant death syndrome. Another study examined the effects of AP on pregnancy outcomes. Most of the available information was from Ontario and British Columbia. Despite inconsistencies among study results and data from elsewhere, evidence from Canadian studies suggest that AP may cause adverse respiratory health effects in children and adverse pregnancy outcomes, and may contribute to infant mortality in Canada.

INTERPRETATION

AP has detrimental health effects among Canadian children. Paediatricians and other health care workers with an interest in child health should encourage parents and children to adhere to smog (AP) advisories. Existing regulatory practices should be reviewed to reduce current levels of ambient air pollutants in Canada.     

Covid-19 in children aged 5–11: Examining the issues surrounding vaccination and public health policy

BackgroundChildren under 12 are now the largest unvaccinated group. Following FDA approval, vaccination of 5–11 year olds is now being encouraged in some countries. We present data on child COVID-related morbidity in Israel and discuss the complexities surrounding vaccinating children aged 5–11.MethodsData were obtained from Israel’s open COVID database regarding new confirmed daily COVID-19 cases, severe hospitalized cases and deaths by age group in Israel from February 2020-November 2021, as well as vaccination rate and adverse events following vaccination.ResultsIn 5–11 year olds, there were 460 hospitalizations, including 72 moderate to critical (0.007% population rate), with 3 deaths (0.0003% population rate). Children (0–19) made up the largest proportion (41%) of cases, but comprised just <0.1% of deaths, and <1% of severe cases. Post-vaccine myocarditis was much lower than severe COVID risk except in boys aged 12–19 where it was equivalent to the risk of mechanical ventilation due to COVID in boys aged 10–19 (12 per 100,000). High numbers of children were quarantined.ConclusionsCOVID risk is minimal for most children though rare complications do occur. Israeli and US pediatric associations have recommended vaccinating children, particularly in high-incidence scenarios where risk–benefit balance is more clear-cut. However only a quarter of eligible parents have vaccinated their children. Parents may consider health grounds but also restrictions on children, population vaccination levels, waning immunity and new variants, and should be provided with clear information to help them make an informed decision. Policymakers should reevaluate the need for isolations, testing and mask-wearing in school age children, which are detrimental to their wellbeing.     

Syncytial variant of nodular sclerosing Hodgkin lymphoma in children: A prognostic factor?

Nodular sclerosing Hodgkin lymphoma (HL) has an excellent prognosis in children. The syncytial variant (SV) of HL in adults represents a clinic pathologic entity with a worse outcome. We report the clinical features and the course of the disease of three children with refractory HL. The three patients with SV were analyzed in a retrospective multi-institutional study conducted in Israel in 51 children diagnosed with refractory or recurrent HL between 1997 and 2014. All the three children developed multiple recurrences soon after diagnosis. All three received at least three different chemotherapy combinations with autologous bone marrow transplantation for two patients, allogenic bone marrow transplantation in one, and immunotherapy in one. One patient died of disease, one is in complete response of the disease but developed a second metastatic malignancy, and one is alive without disease. This retrospective study shows that SV histology may be a prognostic factor for poor outcome in children diagnosed with HL.
