Identifying Practices to Promote Inpatient Adolescent and Influenza Vaccine Delivery.

OBJECTIVES: Many hospitalized children are underimmunized. We assessed the association between hospital immunization practices and tetanus, diphtheria, and acellular pertussis (Tdap), meningococcal, human papillomavirus (HPV), and influenza vaccine delivery. METHODS: An electronic survey regarding hospital vaccine delivery practices was distributed via the Pediatric Health Information System (PHIS) and Pediatric Research in Inpatient Settings networks to PHIS hospitals. Number of vaccines delivered and total discharges in 2018 were obtained from the PHIS database to determine hospital vaccine delivery rates; patients 11 to 18 years old (adolescent vaccines) and 6 months to 18 years old (influenza vaccine) were included. Vaccine delivery rates were risk adjusted by using generalized linear mixed-effects modeling and compared with survey responses to determine associations between the number or presence of specific practices and vaccine delivery. Adjusted HPV and meningococcal vaccine delivery rates could not be calculated because of low delivery. RESULTS: Twenty-nine hospitals completed a survey (57%). 152 499 and 423 046 patient encounters were included for the adolescent and influenza vaccines, respectively. Unadjusted inpatient vaccine delivery rates varied. After adjustment, the number of practices was associated only with influenza vaccine delivery (P = .02). Visual prompts (P = .02), nurse or pharmacist ordering (P = .003), and quality improvement projects (P = .048) were associated with increased influenza vaccine delivery; nurse or pharmacist ordering had the greatest impact. No practices were associated with Tdap vaccine delivery. CONCLUSIONS: The number and presence of specific hospital practices may impact influenza vaccine delivery. Further research is needed to identify strategies to augment inpatient adolescent immunization.

National Inpatient Immunization Patterns: Variation in Practice and Policy Between Vaccine Types.

BACKGROUND: Many hospitalized children are underimmunized, yet little is known about current systems supporting inpatient vaccination. We aim to describe national pediatric inpatient immunization practices and determine if variation exists among adolescent, childhood, and influenza vaccines. METHODS: An electronic survey regarding hospital vaccination practices was sent to physician, nurse, and pharmacy leaders via the Pediatric Research in Inpatient Settings Network in spring 2019. Hospitals reported the presence of various practices to support inpatient vaccination stratified by vaccine type: tetanus, diphtheria, and acellular pertussis, meningococcal, human papillomavirus, childhood series, and influenza. One-way analysis of variance testing compared differences in numbers of practices and χ2 tests compared proportions of sites reporting each practice between vaccine types. Qualitative responses were evaluated via content analysis. RESULTS: Fifty-one of 103 eligible hospitals completed the survey (50%). Standardized policies existed in 92% of hospitals for influenza, 41% for childhood, and 29% for adolescent vaccines. Hospitals identified an average of 5.1 practices to deliver influenza vaccines, compared with 1.5 for childhood; 0.9 for tetanus, diphtheria, and acellular pertussis; 0.7 for meningococcal; and 0.6 for human papillomavirus vaccines (P < .001). Standardized screening tools, visual prompts, standing orders, nurse- or pharmacy-driven screening or ordering, staff education, and quality improvement projects were reported more often for influenza vaccines than other vaccine types (P < .01 for all comparisons). Common barriers to delivery included communication difficulties, lack of systems optimization, and parent and provider discomfort with inpatient immunization. CONCLUSIONS: Existing hospital infrastructure supports influenza vaccine delivery over other vaccine types, potentially creating missed inpatient vaccination opportunities.

Learning from Each Other: A Multisite Collaborative to Reduce Electrolyte Testing.

Inpatient electrolyte testing rates vary significantly across pediatric hospitals. Despite evidence that unnecessary testing exists, providers still struggle with reducing electrolyte laboratory testing. We aimed to reduce serum electrolyte testing among pediatric inpatients by 20% across 5 sites within 6 months. METHODS: A national quality improvement collaborative evaluated standardized interventions for reducing inpatient serum electrolyte testing at 5 large tertiary and quaternary children's hospitals. The outcome measure was the rate of electrolyte laboratory tests per 10 patient-days. The interventions were adapted from a previous single-site improvement project and included cost card reminders, automated laboratory plans via electronic medical record, structured rounds discussions, and continued education. The collaborative utilized weekly conference calls to discuss Plan, Do, Study, Act cycles, and barriers to implementation efforts. RESULTS: The study included 17,149 patient-days across 5 hospitals. The baseline preintervention electrolyte laboratory testing rate mean was 4.82 laboratory tests per 10 patient-days. Postimplementation, special cause variation in testing rates shifted the mean to 4.19 laboratory tests per 10 patient-days, a 13% reduction. There was a wide variation in preintervention electrolyte testing rates and the effectiveness of interventions between the hospitals participating in the collaborative. CONCLUSIONS: This multisite improvement collaborative was able to rapidly disseminate and implement value improvement interventions leading to a reduction in electrolyte testing; however, we did not meet our goal of 20% testing reduction across all sites. Quality improvement collaboratives must consider variation in context when adapting previously successful single-center interventions to a wide variety of sites.

Pediatric Resident Attitudes Toward Inpatient Immunization of Children and Adolescents: Highlighting Differences in Human Papillomavirus Vaccination.

Over a decade after its debut, human papillomavirus (HPV) vaccine coverage remains suboptimal. The inpatient setting presents a largely unexplored opportunity to increase vaccination rates. This study aims to describe pediatric resident attitudes toward inpatient immunization and compare differences by vaccine, in particular HPV. An anonymous survey of beliefs and practices regarding inpatient vaccines was distributed to pediatric resident physicians at a single freestanding urban children's hospital in September 2017. A total of 58 surveys were collected (64% response rate). We found that pediatric residents were more likely to report that they never or rarely discuss the HPV vaccine during hospitalization compared with the primary childhood series (P = .001), Tdap (P = .02), and the influenza vaccine (P < .001), and rarely offer the HPV vaccine during hospitalization compared with childhood vaccines (P = .003) and influenza (P = .001). This suggests that provider hesitancy still exists for the HPV vaccine, presenting opportunities for further education and inpatient interventions.

Pediatric Inpatient Immunizations: A Literature Review.

CONTEXT: Timely vaccine uptake in children remains suboptimal. Eliminating missed opportunities is key to increasing childhood immunization rates, and hospitalization offers another potential setting to vaccinate. OBJECTIVE: To better understand pediatric inpatient immunization programs, including vaccination rates of inpatients, parental and provider attitudes, barriers to vaccine delivery, and interventions to increase provision of inpatient vaccines. DATA SOURCES: A search was conducted of PubMed, Embase, and Web of Science to identify articles and conference abstracts related to pediatric inpatient immunization. STUDY SELECTION: Inclusion criteria were studies published in English between January 1990 and January 2019 in which pediatric vaccination in the hospital setting was discussed. Findings from 30 articles and conference abstracts were summarized and organized by topic area. DATA EXTRACTION: Abstracts were screened for relevance, articles were read, and themes were identified. RESULTS: Children who are hospitalized have been shown to have lower immunization rates compared with the general population, with 27% to 84% of pediatric inpatients due or overdue for vaccines nationally when verified with official records. Unfortunately, little is done to catch up these children once they have been identified. Access to accurate vaccine histories remains a major barrier in inpatient immunization programs because providers frequently under document and parents over recall a child's vaccine status. Strategies identified to increase inpatient vaccination included creation of a multidisciplinary immunization team, educational interventions, visual reminders, catch-up vaccine plans, order sets, and nursing-driven screening. When offered inpatient vaccination, a majority of parents accepted immunizations for their children. CONCLUSIONS: Hospitalization may provide an opportunity to augment vaccine uptake. Further research is needed to develop evidence-based strategies to overcome barriers to inpatient vaccination.
