Lo ZC, Sobota AE. Maintenance of a High Influenza Vaccination Rate and Improvement in Health Outcomes in a Pediatric Sickle Cell Disease Clinic. J Pediatr Hematol Oncol 2022; 44:e46-e50. [PMID: 33974583 PMCID: PMC8581069 DOI: 10.1097/mph.0000000000002192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2020] [Accepted: 03/26/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND Children with sickle cell disease (SCD) are at high-risk of complications from influenza and should receive an influenza vaccination seasonally. Despite this recommendation, vaccination rates remain suboptimal. Boston Medical Center (BMC) previously achieved high influenza vaccination rates among its pediatric patients with SCD. The purpose of this study was to determine whether this high vaccination rate has been maintained and whether it has influenced outcome measures. PATIENTS AND METHODS A retrospective chart review was conducted in the hematology clinic at an urban, academic medical center. Fisher's exact test and the independent samples t test were used to determine if there were any significant differences in characteristics between patients with influenza and patients without influenza, as well as between vaccinated and unvaccinated patients. Influenza vaccination rate, influenza-related hospitalization rate, and influenza-positive rate were collected and compared with reported rates. RESULTS Data from 124 pediatric patients with SCD were examined. The influenza vaccination rate for pediatric patients with SCD at BMC (90.32%) was higher than previous studies that were not conducted at BMC, while BMC's influenza-related hospitalization rate (0) and influenza-positive rate (4.84%) were lower than other studies. Subjects who contracted influenza were younger than those who did not (4.67 vs. 10.03 y, P=0.005). CONCLUSIONS BMC has maintained a high influenza vaccination rate among pediatric patients with SCD. BMC's vaccination strategy has been successful at improving outcome measures including rates of influenza and influenza hospitalizations without requiring additional staff. Such efforts should be replicated at other centers.

Influenza vaccination rates and hospitalizations among Medicaid enrollees with and without sickle cell disease, 2009-2015. Pediatr Blood Cancer 2021; 68:e29351. [PMID: 34542932 PMCID: PMC10578616 DOI: 10.1002/pbc.29351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 08/09/2021] [Accepted: 08/26/2021] [Indexed: 11/06/2022]
Abstract
BACKGROUND Personswith sickle cell disease (SCD) face increased risks for pulmonary and infection-related complications. This study examines influenza vaccination coverage and estimates influenza-related morbidity among Medicaid enrollees with and without SCD. PROCEDURE Influenza vaccination coverage and hospitalizations related to influenza and pneumonia/acute chest syndrome (ACS) during each influenza season from 2009-2010 to 2014-2015 were assessed among enrollees in the IBM MarketScan® Multi-State Medicaid Database. Enrollees with SCD were identified as enrollees with greater than or equal to three claims listing SCD within a 5-year period during 2003-2017. Vaccinations were identified in outpatient claims. Hospitalizations associated with influenza or pneumonia/ACS were identified using inpatient claims. This study includes a series of cross-sectional assessments by season. RESULTS From 2009-2010 through 2014-2015 seasons, the SCD sample ranged from 5044 to 8651 enrollees; the non-SCD sample ranged from 1,841,756 to 3,796,337 enrollees. Influenza vaccination coverage was higher among enrollees with SCD compared with enrollees without SCD for all seasons (24.5%-33.6% and 18.2%-22.0%, respectively). Age-standardized rates of influenza-related hospitalizations were 20-42 times higher among SCD enrollees compared with non-SCD enrollees, and ACS/pneumonia hospitalizations were 18-29 times higher. Among enrollees with SCD, influenza-related hospitalization rates were highest among children aged 0-9 years. Among enrollees without SCD, influenza-related hospitalization rates were highest among adults aged 40-64 years. CONCLUSIONS Although vaccine coverage was higher in persons with versus without SCD, efforts to increase influenza coverage further are warranted for this high-risk group, who experienced markedly higher rates of influenza and ACS/pneumonia hospitalizations during each season.

Abstract
Immunocompromised children are at increased risk of severe illness from vaccine-preventable infections. However, inadequate vaccine coverage remains a concern. This scoping review sought to determine the current state of knowledge regarding vaccine coverage of immunocompromised children. Bibliographic databases were searched for primary research from any year. Data were analyzed quantitatively and narratively. Ninety-seven studies met inclusion criteria. The most commonly studied vaccines were pneumococcal (n = 46), influenza (n = 44), diphtheria/tetanus/pertussis/poliomyelitis/Haemophilus influenzae type B/hepatitis B-containing (n = 36), and measles- and/or mumps- and/or rubella-containing (n = 29). Immunocompromising conditions studied included cancer/stem cell transplants (n = 24), solid organ transplants (n = 23), sickle cell disease (n = 21), immunosuppressive therapy (n = 14), human immunodeficiency virus (n = 12), splenectomy (n = 4), and primary immunodeficiency (n = 2). As more children are treated with immunosuppressive therapies, it is critical to identify whether they are being appropriately vaccinated for age and condition. We identified gaps in the current state of knowledge for specific vaccine types in specific immunocompromised populations.

Air Drep-A Retrospective Study Evaluating the Influence of Weather Conditions and Viral Epidemics on Vaso-Occlusive Crises in Patients with Sickle Cell Disease Living in French Guiana. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16152724. [PMID: 31370136 PMCID: PMC6695746 DOI: 10.3390/ijerph16152724] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Revised: 07/02/2019] [Accepted: 07/03/2019] [Indexed: 11/17/2022]
Abstract
(1) Objectives: French Guiana is the French territory most affected by sickle cell disease (SCD). This study investigates the associations between different environmental factors relative to climate, infectious outbreaks, and emergency visits or weekly hospital admissions for vaso-occlusive crisis (VOC). The identification of risk factors would lead to better patient care and patient management, and more targeted prevention and therapeutic education for patients with SCD in French Guiana. (2) Methods: This study was performed using data collected from the medicalized information system and emergency medical records of Cayenne General Hospital, between 1 January 2010 and 31 December 2016. ARIMA models were used to investigate the potential impact of weather conditions and flu epidemics on VOC occurrence. (3) Results: During the study period, 1739 emergency visits were recorded among 384 patients, of which 856 (49.2%) resulted in hospitalization, 811 (46.6%) resulted in hospital discharge, and 72 (4.2%) in another orientation. Decreased temperature and decreased humidity were both independent factors associated with an increase of VOC cases (p = 0.0128 and p = 0.0004, respectively). When studying severe VOC (leading to hospitalization, with or without prior emergency visit), 2104 hospital admissions were recorded for 326 patients. The only factor associated with severe VOC, in the multivariate analysis, was flu epidemics (p = 0.0148). (4) Conclusions: This study shows a link between climate, flu epidemics, and VOC in French Guiana. Patient’s awareness of risks related to climate and flu epidemics should be encouraged, as home prevention measures can help avoid painful crises. Moreover, physicians should encourage patients to get immunized for influenza every year.

Abstract
OBJECTIVE To evaluate England's NHS newborn sickle cell screening programme performance in children up to the age of 5 years. DESIGN Cohort of resident infants with sickle cell disease (SCD) born between 1 September 2010 and 31 August 2015 and followed until August 2016. PARTICIPANTS 1317 infants with SCD were notified to the study from all centres in England and 1313 (99%) were followed up. INTERVENTIONS Early enrolment in clinical follow-up, parental education and routine penicillin prophylaxis. MAIN OUTCOME MEASURES Age seen by a specialist clinician, age at prescription of penicillin prophylaxis and mortality. RESULTS All but two resident cases of SCD were identified through screening; one baby was enrolled in care after prenatal diagnosis; one baby whose parents refused newborn screening presented symptomatically. There were 1054/1313 (80.3%, 95% CI 78% to 82.4%) SCD cases seen by a specialist by 3 months of age and 1273/1313 (97%, 95% CI 95.9% to 97.8%) by 6 months. The percentage seen by 3 months increased from 77% in 2010 to 85.4% in 2015. 1038/1292 (80.3%, 95% CI 78.1% to 82.5%) were prescribed penicillin by 3 months of age and 1257/1292 (97.3%, 95% CI 96.3% to 98.1%) by 6 months. There were three SCD deaths <5 years caused by invasive pneumococcal disease (IPD) sensitive to penicillin. CONCLUSION The SCD screening programme is effective at detecting affected infants. Enrolment into specialist care is timely but below the programme standards. Mortality is reducing but adherence to antibiotic prophylaxis remains important for IPD serotypes not in the current vaccine schedule.

Abstract
OBJECTIVE In this study, we investigated the influence of electronic health records (EHR) and electronic vaccination schedule applications on the vaccination status of patients who were admitted to our Center for the treatment of sickle cell disease (SCD). METHODS The vaccination status against influenza and pneumococcus infection was determined in 93 patients who were admitted to the hematology outpatient clinic, Baskent University Adana Hospital from April 2004 to March 2009. The vaccination status was then re-evaluated following establishment of EHR and electronic vaccination schedules in 2012. RESULTS Of the 93 patients with SCD 21.5% (n = 20) were vaccinated against pneumococcus and 21.5% (n = 20) were regularly vaccinated against influenza. When the vaccination rates of 59 of 93 patients who presented for their regular control examinations were analyzed following establishment of EHR and vaccination schedules in 2012, these rates were 49.2% (n = 29) and 50.8% (n = 30) for influenza and pneumococcus, respectively, after EHR; there were 23.7% (n = 14) and 20.3% (n = 12), respectively, before EHR. A statistically significant difference was found between the vaccination rates before and after EHR (p < 0.05). CONCLUSION Although viral and bacterial infections are life-threatening health problems in patients with SCD, the vaccination rates were low in high-risk patients. However, these rates increased after application of electronic vaccination schedules.

Abstract
Sickle cell disease (SCD) is a major global health concern. Patients with SCD experience disproportionately greater morbidity and mortality in response to influenza infection than do others. Viral infection is one contributing factor for the development of Acute Chest Syndrome (ACS), a major cause of morbidity and mortality in SCD patients. We determined whether the heightened sensitivity to influenza infection could be reproduced in the two different SCD murine models to ascertain the underlying mechanisms of increased disease severity. In agreement with clinical observations, we found that both genetic and bone marrow-transplanted SCD mice had greater mortality in response to influenza infection than did wild-type animals. Despite similar initial viral titers and inflammatory responses between wild-type and SCD animals during infection, SCD mice continued to deteriorate and failed to resolve the infection, resulting in increased mortality. Histopathology of the lung tissues revealed extensive pulmonary edema and vascular damage following infection, a finding confirmed by heightened vascular permeability following virus challenge. These findings implicate the development of exacerbated pulmonary permeability following influenza challenge as the primary factor underlying heightened mortality. These studies highlight the need to focus on prevention and control strategies against influenza infection in the SCD population.

Abstract
Ambulatory care clinical pharmacy services have expanded beyond primary care settings, but literature supporting the benefits of clinical pharmacy involvement with patients who have rare diseases such as sickle cell disease (SCD) is lacking. Hydroxyurea is the only agent approved by the U.S. Food and Drug Administration for the treatment of SCD; full benefit in controlling pain episodes and other complications is achieved through monitored escalation to a maximum tolerated dose. The primary objective of this analysis was to evaluate the impact of a newly implemented clinical pharmacy service on the management of patients with SCD. We performed a retrospective cross-sectional analysis of 385 adults with SCD who received care between January 1, 2014, and December 31, 2014, at a single Sickle Cell Outpatient Center that implemented a clinical pharmacy service in August 2013. Data were collected on hydroxyurea dose escalation, immunization completion rates, and health maintenance metrics (screening for nephropathy with microalbuminuria testing, retinopathy with annual retinal examinations, and pulmonary hypertension with echocardiography). The impact of the clinical pharmacy service on quality measurements was evaluated by using univariate and multivariate analyses. The number of pharmacist encounters, defined as a clinic visit when a clinical pharmacist interacted with a patient as documented in the medical records, was associated with an improved hydroxyurea dose escalation rate (odds ratio [OR] 1.48, 95% confidence interval [CI] 1.07-2.05, p=0.02). Immunization rates for the 23-valent pneumococcal polysaccharide vaccine, the 13-valent pneumococcal conjugate vaccine, and influenza vaccine were 66%, 47%, and 62%, respectively. The number of pharmacist encounters was associated with improved immunization completion rates (OR 1.38, 95% CI 1.17-1.62, p<0.001). Improved screening for microalbuminuria (OR 2.14, 95% CI 1.60-2.86, p<0.001) and sickle cell retinopathy (OR 1.16, 95% CI 1.00-1.35, p=0.05) were also associated with the number of pharmacist encounters. A new clinical pharmacy service implemented in managing a rare disease, SCD, was associated with an improved hydroxyurea dose escalation rate, immunization completion rates, and health maintenance metrics.

Abstract
AIMS To assess the level of adherence of patients with sickle cell disease to the advised vaccination schedule with respect to the Sickle Cell Society guidelines on vaccination [1,2]. METHODS A retrospective audit of patients' vaccination records was carried out between July 2012 and June 2013 on a sample of 80 patients over the age of 16, who attended Newham University Hospital accident and emergency (A&E) department with a presenting complaint coded as "sickle cell". A re-audit was conducted from January 2014 to December 2014 to close the audit loop. Chi-squared and Fisher's exact tests were used to compare the results. RESULTS The initial audit and re-audit identified 80 and 86 patients, respectively. Only 2 (2012-2013) and 7 (2014) patients had a complete up-to-date vaccination profile. 24 (30%) patients had up-to-date influenza vaccination, increasing to 43 (50%, P=0.0062) when re-audited. 33 (41%) had current pneumococcal vaccinations, increasing to 38 (44%, P=0.7874). Uptake rates for vaccinations against Meningococcal group C (MenC), Haemophilus influenzae B (HiB) and Hepatitis B virus (HBV) were under 31% in both audits. A significant improvement in vaccination rate was observed for all vaccinations except pneumococcal and HBV. CONCLUSIONS Although significant improvements have been demonstrated, this audit shows a low level of adherence to the advised vaccination schedule. The study also highlighted a shortfall in appropriate record keeping, reducing the potential for detailed conclusions being drawn in relation to the childhood vaccinations against MenC, HiB and HBV. Implementation of a new database of vaccination history, raising GP awareness and patient education seminars has lead to a significant improvement in vaccination rates locally and the authors hope that this may be replicated in other centres. There may be potential to increase rates further by administering vaccinations to inpatients.

Abstract
BACKGROUND Children with sickle cell disease (SCD) are at increased risk of complications from influenza. However, despite widespread recommendations that these patients receive an annual influenza immunization, reported vaccination rates remain very low at under 50%. PROCEDURE Our aim was to increase the influenza vaccination rate among our pediatric patients with SCD aged 6 months to 21 years over two influenza seasons, 2012-2013 and 2013-2014, to 80%, consistent with the Health People 2020 goal. We used multiple quality improvement methods, based on the literature and our previous experience in other aspects of SCD care, including parent and provider education, enhancement of our EHR, use of a SCD patient registry and reminder and recall done by a patient navigator. RESULTS We vaccinated 80% of our pediatric patients with SCD for influenza during the 2012-2013 season and 90% of patients in 2013-2014. Our early season vaccination rates were nearly double that of those for the general population. CONCLUSIONS Use of quality improvement methods can increase rates of influenza vaccination for this high-risk population, suggesting that less health care utilization and lower cost might result.

Abstract
The purpose of this study was to identify rates of adherence for three outpatient quality indicators noted by Wang et al. (Pediatrics 2011;128:484–493): (1) influenza vaccine, (2) pneumococcal immunizations, and (3)penicillin prophylaxis in patients with sickle cell disease (SCD) in a Medicaid sample. These variables were chosen based on Wang and colleagues' suggestion that these variables are important for the assessment of the quality of care of children with SCD. We hypothesized that the overall rate of adherence would be poor with adults having worse rates of adherence than children. We conducted a retrospective cohort study using the Wisconsin State Medicaid database over a 5-year period to assess the preventative medication adherence of individuals with SCD. Preventative medication variables in this study included influenza vaccination,pneumococcal immunizations (PCV7, PPV23), and penicillin prophylaxis. As predicted, the 2003–2007 Wisconsin State Medicaid database showed patients with SCD had low adherence in terms of recommended influenza vaccinations (21.58% adherent), PPV23 pneumococcal immunizations (43.47% adherent), and penicillin prophylaxis (18.18% adherent). Pneumococcal immunizations for PCV7 were higher than expected (77.27%adherent). Although children tended to adhere to recommended preventative medications more than adults,overall adherence was low. Although we cannot explain why adherence is low, it is likely due to multiple factors at the patient- and provider-level. We encourage patients and providers to create a partnership to meet adherence recommendations, and we describe our strategies for increasing adherence.

Abstract
Children with primary immunodeficiencies, sickle cell disease and cystic fibrosis are at risk to develop invasive bacterial infections caused by respiratory tract pathogens, in particular Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureus. This review article evaluates the role of nasopharyngeal colonization by these pathogens in the high prevalence of respiratory and invasive infections in children with inherited disorders affecting the immune system or the respiratory tract. We conclude that respiratory and invasive diseases that occur in children with primary immunodeficiencies or sickle cell disease are probably a result of increased nasopharyngeal colonization rates compared with healthy children. However, when the inherited disorder is characterized by local airway abnormalities such as in cystic fibrosis, enhanced nasopharyngeal colonization does not seem to play a major role in invasive disease risk. As the evidence for the role of nasopharyngeal colonization in disease risk in these specific patient groups partly comes from experimental studies and animal models, longitudinal studies in children are needed. Detailed understanding of the effect of colonization on the development of respiratory and invasive infections in children with primary immunodeficiencies, sickle cell disease or cystic fibrosis provides a justification for the selective introduction of vaccination and prophylactic antibiotic treatment. Recommendations for the use of (preventive) therapeutic strategies in these patient groups taking into account disease-specific immunologic mechanisms underlying colonization and disease are described.

Abstract
Individuals with sickle cell disease (SCD) demonstrate an increased susceptibility to invasive bacterial infections (IBI). The most common organisms causing IBI are Streptococcus pneumoniae, nontyphi Salmonella species and Haemophilus influenzae type b (Hib). IBI are the most common causes of death in children below 5 years of age with SCD. Increased susceptibility to IBI is because of several factors including dysfunctional antibody production and opsonophagocytosis as well as defective splenic clearance. Early diagnosis of Hib and pneumococcal infections combined with antibiotic prophylaxis and immunization programs, could lead to significant improvements in mortality, especially in Africa.

Abstract
Influenza causes excess morbidity in sickle cell disease (SCD). H1N1 pandemic influenza has been severe in children. To compare H1N1 with seasonal influenza in SCD (patients younger than 22), we reviewed medical records (1993-2009). We identified 123 cases of laboratory-confirmed influenza (94 seasonal, 29 H1N1). Those with seasonal influenza were younger (median 4.4 vs 8.7 years old, P = .006) and had less asthma (24% vs 56%, P = .002). Those with H1N1 influenza more often had acute chest syndrome (ACS; 34% vs 13%, P = .01) and required intensive care (17% vs 3%, P = .02), including mechanical ventilation (10% vs 0%, P = .02). In multivariate analysis, older age (odds ratio [OR] 1.1 per year, P = .04) and H1N1 influenza (OR 3.0, P = .04) were associated with ACS, and older age (OR 1.1 per year, P = .02) and prior ACS (OR 3.3 per episode in last year, P < .006) with intensive care. Influenza, especially H1N1, causes critical illness in SCD and should be prevented.
