Cost analysis of COVID-19 test result notification using an automated messaging system compared to a staff caller practice in Alberta.

SETTING: In Alberta, polymerase chain reaction (PCR) COVID-19 tests were an important step in detecting and isolating contagious individuals throughout the pandemic. Initially, a staff member provided results to all PCR COVID-19 test clients by phone. As the number of tests increased, new approaches were essential for timely result notification. INTERVENTION: An innovative automated IT system was introduced during the pandemic to reduce workloads and support timely result notification. At the time of the COVID-19 test booking and again following swabbing, clients had an option to consent to receive their test results via an automated text or voice message. Prior to implementation, a privacy impact assessment was approved, a pilot was undertaken, and changes to lab information systems were made. OUTCOMES: Health administration data were used in a cost analysis to compare the unique costs associated with the novel automated IT practice (e.g., administration, integration, messages, staffing costs) and a hypothetical staff caller practice (e.g., administration, staffing costs) for negative test results. The costs of sharing 2,161,605 negative test results in 2021 were assessed. The automated IT practice demonstrated a cost savings of $6,272,495 over the staff caller practice. A follow-up analysis determined the cost savings threshold of 46,463 negative tests to break even. IMPLICATIONS: Using an automated IT practice for consenting clients can be a cost-effective approach to reach clients in a timely manner during a pandemic or other instances warranting direct notification. This approach is being explored for test result notification of other communicable diseases in other contexts.

RéSUMé: LIEU: En Alberta, les tests de réaction de polymérisation en chaîne (PCR) pour la COVID-19 ont représenté une étape importante dans la détection et l'isolement des personnes contagieuses tout au long de la pandémie. Au début, un membre du personnel communiquait par téléphone les résultats de tous les tests PCR de la COVID-19 aux usagers et usagères. Avec l'augmentation du nombre de tests, il a absolument fallu trouver de nouvelles façons de communiquer les résultats rapidement. INTERVENTION: Un système de TI automatisé novateur a été introduit durant la pandémie pour alléger la charge de travail et favoriser la communication rapide des résultats des tests. Au moment de la réservation d'un test de dépistage de la COVID-19 et après l'écouvillonnage, les usagers et usagères pouvaient consentir à recevoir leurs résultats via un message texte automatisé ou un message vocal. Avant la mise en œuvre, une évaluation des facteurs relatifs à la vie privée a été approuvée, un projet pilote a été mené, et des changements ont été apportés aux systèmes d'information des laboratoires. RéSULTATS: Les données administratives sanitaires ont servi à effectuer une analyse des coûts visant à comparer les coûts spécifiquement associés à la nouvelle pratique de TI automatisée (p. ex. frais d'administration, d'intégration, de messages, de personnel) et ceux d'une hypothétique pratique d'appel par un membre du personnel (p. ex. frais d'administration, de personnel) pour les tests négatifs. Les coûts de communication des résultats de 2 161 605 tests négatifs en 2021 ont été évalués. La pratique de TI automatisée a représenté des économies de 6 272 495 $ par rapport à la pratique d'appel par un membre du personnel. Selon une analyse de suivi, le seuil de rentabilité était atteint après 46 463 tests négatifs. CONSéQUENCES: L'utilisation d'une pratique de TI automatisée pour les usagers et usagères ayant consenti à cette option peut être une méthode efficace par rapport au coût pour joindre rapidement les usagères et usagers lors d'une pandémie ou dans d'autres cas où une notification directe est justifiée. Cette méthode est explorée pour la communication des résultats de tests d'autres maladies transmissibles dans d'autres contextes.

Exploring the Alberta Health Services COVID-19 provincial public health integrated outbreak prevention, preparedness, management, and response interventions to support congregate and communal living sites in Alberta.

SETTING: On March 17, 2020, a state of public health emergency was declared in Alberta under the Public Health Act in response to the COVID-19 pandemic. Congregate and communal living sites were environments with a high risk of exposure to and transmission of COVID-19. Consequently, provincial efforts to prevent and manage COVID-19 were required and prioritized. INTERVENTION: During the first 9 months of the pandemic, vaccines were unavailable and alternate strategies were used to prevent and manage COVID-19 (e.g., physical distancing, masking, symptom screening, testing, isolating cases). Alberta Health Services worked with local, provincial, and First Nations and Inuit Health Branch stakeholders to deliver interventions to support congregate and communal living sites. Interventions included resources and site visits to support prevention and preparedness, and the creation of a coordinated response line to serve as a single point of contact to access information and services in the event of an outbreak (e.g., guidance, testing, personal protective equipment, reporting). OUTCOMES: Data from an internal monitoring dashboard informed intervention uptake and use. Online survey results found high levels of awareness, acceptability, appropriateness, and use of the interventions among congregate and communal living site administrators (n = 550). Recommendations were developed from reported experiences, challenges, and facilitators, and processes were improved. IMPLICATIONS: Provincially coordinated prevention, preparedness, and outbreak management interventions supported congregate and communal living sites. Efforts to further develop adaptive system-level approaches for prevention and preparedness, in addition to communication and information sharing in complex rapidly changing contexts, could benefit future public health emergencies.

RéSUMé: LIEU: Le 17 mars 2020, un état d'urgence sanitaire a été déclaré en Alberta en vertu de la Loi sur la santé publique pour riposter à la pandémie de COVID-19. Les habitations collectives étaient des environnements qui présentaient un risque élevé d'exposition à la COVID-19 et de transmission du virus. Des efforts provinciaux pour prévenir et gérer la COVID-19 ont donc été nécessaires et se sont vu accorder la priorité. INTERVENTION: Comme des vaccins n'étaient pas disponibles au cours des neuf premiers mois de la pandémie, d'autres stratégies ont été utilisées pour prévenir et gérer la COVID-19 (p. ex. distanciation physique, port du masque, dépistage des symptômes, tests, isolation des cas). Les Services de santé de l'Alberta ont travaillé avec les acteurs locaux et provinciaux et les fonctionnaires de la Direction générale de la santé des Premières nations et des Inuits pour mener des interventions à l'appui des habitations collectives. Ces interventions ont compris des ressources et des visites sur place pour appuyer la prévention et la préparation, et la création d'une ligne d'intervention coordonnée qui a servi de guichet unique d'accès à l'information et aux services en cas d'éclosion (p. ex. conseils, tests, équipement de protection individuelle, déclaration des cas). RéSULTATS: Les données d'un tableau de bord interne ont permis d'en savoir plus sur la popularité et l'utilisation de ces interventions. Les résultats d'un sondage en ligne ont fait état de niveaux élevés de connaissance, d'acceptabilité, de pertinence et d'utilisation des interventions chez les administrateurs d'habitations collectives (n = 550). Des recommandations ont été élaborées à partir des expériences signalées et des éléments positifs et négatifs, et les processus ont été améliorés. CONSéQUENCES: Des interventions de prévention, de préparation et de gestion des éclosions coordonnées à l'échelle provinciale ont soutenu les habitations collectives. Il pourrait être utile pour les futures urgences sanitaires de développer ces approches d'adaptation systémiques pour la prévention et la préparation, en plus des communications et de l'échange d'informations dans des contextes en évolution rapide.

Meeting case investigation and contact tracing needs during COVID-19 in Alberta: the development and implementation of the Alberta Health Services Pod Partnership Model.

SETTING: In Alberta, a small team of specialized public health experts typically complete case investigation and contact tracing. High COVID-19 case counts and a shortage of trained public health professionals required a rapid and significant adaptation of staffing models to meet the population's needs. INTERVENTION: A tiered, interdisciplinary staffing model, based on those in critical care, was developed, piloted, and implemented in the Alberta Health Services' Communicable Disease Control department in late 2020 to complete case investigation and contact tracing. The final model included novice, non-regulated professionals divided into pods of four to six investigators, led by an experienced regulated investigator. Team leads oversaw five pods. Communicable disease nurses provided an additional tier of clinical expertise. During the model development, roles and responsibilities of team members were delineated, ratios for supervision were tested, and rapid training was provided. OUTCOMES: The tiered staffing model began in November 2020 with staff members in two pods. At its peak in early May 2021, 72 pods of 502 non-regulated members, 134 regulated investigators, and 4 communicable disease nurses completed 780-973 case investigations daily, or 40-45% of all positive cases in Alberta. In comparison, the same number of regulated investigators working independently in the traditional staffing model without non-regulated pods completed, on average, 249 case investigations daily. IMPLICATIONS: A tiered staffing model can be effective at maximizing the skills of the experienced members of the case investigation team to maintain case investigation and contact tracing activities during a pandemic.

RéSUMé: LIEU: En Alberta, une petite équipe de spécialistes de la santé publique mène généralement les enquêtes et la recherche des contacts. Un nombre élevé de cas de COVID-19 et une pénurie de professionnels de la santé publique formés ont nécessité une adaptation rapide et importante des modèles de dotation des équipes pour répondre aux besoins de la population. INTERVENTION: Un modèle de dotation interdisciplinaire à plusieurs niveaux axé sur les patients aux soins intensifs a été élaboré, mis à l'essai et appliqué par la division de la lutte contre les maladies transmissibles des Services de santé de l'Alberta vers la fin de 2020 pour mener les enquêtes et la recherche des contacts. Le modèle final incluait des membres novices de professions non réglementées divisés en modules de quatre à six chercheurs et chercheuses sous la direction d'un chercheur ou d'une chercheuse d'expérience membre d'une profession réglementée. Les chefs d'équipes supervisaient cinq modules. Des infirmières et infirmiers en maladies transmissibles constituaient un niveau supplémentaire d'expérience clinique. Durant l'élaboration du modèle, les fonctions des membres des équipes ont été définies, les ratios d'encadrement ont été testés, et une formation rapide a été fournie. RéSULTATS: L'application du modèle de dotation à plusieurs niveaux a commencé en novembre 2020 avec des effectifs dans deux modules. À son sommet au début de mai 2021, 72 modules, composés de 502 membres de professions non réglementées, de 134 chercheurs et chercheuses de professions réglementées et de 4 infirmières et infirmiers en maladies transmissibles, ont mené de 780 à 973 enquêtes par jour, ce qui englobait entre 40 et 45 % des cas positifs en Alberta. À titre de comparaison, le même nombre de chercheurs et de chercheuses de professions réglementées, travaillant indépendamment selon le modèle de dotation classique sans modules non réglementés, a mené en moyenne 249 enquêtes par jour. CONSéQUENCES: Un modèle de dotation à plusieurs niveaux peut maximiser les compétences des membres expérimentés de l'équipe d'enquête pour maintenir les activités d'enquête et de recherche des contacts durant une pandémie.

Social equity in Human Papillomavirus vaccination: a natural experiment in Calgary Canada.

BACKGROUND: The Alberta Immunization Program offers a vaccine against the Human Papillomavirus (HPV) free of charge to all girls in Grades 5 and 9. The vaccine is provided in two different service delivery models depending upon the acceptance of the program by the local school board. Vaccinations may be provided "in-school" or in "community" through appointments at Public Health Clinics. The purpose of this study was to determine whether there was a difference in vaccine uptake in Calgary between the two service delivery models, "in-school" and "community", and to examine if socioeconomic status (SES) was a contributing factor. METHODS: Individual data from the Calgary Zone Public Health vaccination database for all grade 5 and 9 girls in Calgary for school years 2008-2011 were analyzed using descriptive statistics. These data included vaccination records for 35,592 girls. Logistic regression was used to examine the effect of delivery system and SES status on being vaccinated, controlling for school type. RESULTS: HPV vaccination completion rates were 75% (95% confidence interval = 74.7%, 75.8%) for girls with an "in-school" compared to 36% (95% confidence interval = 35.3%, 37.2%) for girls in schools with a "community" service delivery model. A girl's neighbourhood SES was related to the likelihood of being HPV vaccinated depending on the service delivery model available to her. For girls attending a Public school with an "in-school" delivery model, the proportion completing vaccination increased as SES decreased (high SES = 79%; medium SES = 79%; low SES = 83%; p-value<0.001). For girls attending Calgary Catholic School District schools with the "community" delivery model there was a decrease in immunization rates from high and mid to low SES (high SES = 41%; medium SES = 42%; low SES = 34%; p-value<0.001). These results show that those with lower SES were differentially disadvantaged by not having access to an "in-school" vaccination delivery model. CONCLUSION: Service delivery models make a difference in HPV vaccination completion rates and create inequities for health protection and disease prevention based on socioeconomic status.

Healthy eating guidelines for a school jurisdiction: collaborative design and implementation.

PURPOSE: Healthy eating is a determinant of optimal growth, and schools provide an ideal setting in which to influence students' diets. The Healthy Eating Guidelines Initiative (HEGI) was a partnership among education, health, and community stakeholders to develop and implement healthy eating guidelines across a school jurisdiction. An evaluation was conducted to examine the potential impact of the HEGI on the school food environment and students' self-reported diets. METHODS: All schools in the jurisdiction were invited to participate in the evaluation. Participating schools included elementary, middle, high, and mixed grades schools. A school environment assessment and a student questionnaire were used to collect data before and after the HEGI. RESULTS: Twenty-two (71%) of 31 schools participated in the evaluation. The guidelines were successfully implemented in 17 of these 22 schools. Overall, a greater proportion of students reported healthier eating behaviours at the conclusion of the HEGI. In particular, a greater proportion of students in schools with cafeteria-style food service showed significantly improved self-reported dietary behaviours. These changes were not seen among students at schools with limited or no on-site food service. CONCLUSIONS: The findings are consistent with those of previous studies, and indicate that guidelines for a school jurisdiction can have a positive impact on the school food environment and students' food intake. The HEGI shows promise as a strategy to promote healthy eating among students.

A growth status measurement pilot in four Calgary area schools: perceptions of grade 5 students and their parents.

Reliable measures of growth in children are necessary for planning and evaluating obesity prevention programs. Currently, measured growth data are unavailable in Calgary for school-age children. This single sample, cross-sectional study included Grade 5 students and their parents. Height and weight measurements of 305 students (68% of those eligible) were taken in private in June 2007 and converted to Body Mass Index (BMI) categories. All but one student (99.7%) completed a questionnaire assessing perceptions of the measurement process. Parents received their child's growth data, an information package on healthy eating and active living, additional resources, and a questionnaire. A third of parents completed the questionnaire. Most students (94.1%) reported feeling "OK" or "Happy" about being measured. In addition, 93.2% of parents reported having "Low" or "Neutral" concerns about the measurement. Furthermore, 28.1% of responding parents reported seeking additional resources or considered making a lifestyle change for their family following the pilot. Measurement of students completed in private by nurses was acceptable to participants.

Estimation of risks associated with paediatric cochlear implantation.

The objectives of this study were to estimate the rates of complications associated with paediatric cochlear implantation use: a) at one Canadian cochlear implant (CI) centre, and b) in the published literature. It comprised a retrospective hospital-based chart review and a concurrent review of complications in the published literature. There were 224 children who had undergone surgery from 1994 to June 2007. Results indicate that the rates of complications at the local Canadian paediatric CI centre are not significantly different from the literature rates for all examined complication types. This hospital-based retrospective chart review and review of the literature provide readers with an estimation of the risks to aid in evidence-based decision-making surrounding paediatric cochlear implantation.

Bilateral paediatric cochlear implants: a critical review.

A recent trend has been the implantation of bilateral cochlear implants (CIs) for children with severe to profound hearing loss. A review of available research on bilateral CIs was conducted to determine the support for this trend. A replicable review was undertaken to evaluate published research studies that examined the effectiveness of bilateral paediatric cochlear implantation. Databases, reference lists, and journals were searched for relevant documents using a pre-determined search protocol. Twenty-nine articles met the review's inclusion criteria and were retrieved and reviewed. This review adds to the previously published reviews on the topic by identifying additional paediatric studies. Sound localization and speech recognition in noise appear to be improved with bilateral compared to unilateral cochlear implants. Similarly, evoked potential measures suggest improved morphology when the second CI is implanted early. Well-designed and controlled studies that explore a variety of outcomes including cost-effectiveness, quality of life, speech, language, and psycho-educational measures should be further explored in order to provide additional support for parents and clinicians confronted with the bilateral cochlear implant decision.

Fitting audiology within the population health perspective.

The population health perspective has become increasingly apparent in the medical, public health, and policy literature. This article emphasizes the value of applying the population health perspective and associated frameworks to the rehabilitative sciences and particularly to the field of audiology. Key components of the population health perspective--including the determinants of health, the importance of evidence-based practice, and the value of transdisciplinarity--are used to illustrate the relevance of population health to the field of audiology. Using these key concepts from a population health framework and examples from audiology, the adoption of a population health perspective is proposed.
