Measuring the timeliness of childhood vaccinations: Using cohort data and routine health records to evaluate quality of immunisation services.

ABSTRACT:

Background

To achieve full benefits of vaccination programmes, high uptake and timely receipt of vaccinations are required.

Objectives

To examine uptake and timeliness of infant and pre-school booster vaccines using cohort study data linked to health records.

Methods

We included 1782 children, born between 2000 and 2001, participating in the Millennium Cohort Study and resident in Wales, whose parents gave consent for linkage to National Community Child Health Database records at the age seven year contact. We examined age at receipt, timeliness of vaccination (early, on-time, delayed, or never), and intervals between vaccine doses, based on the recommended schedule for children at that time, of the following vaccines: primary (diphtheria, tetanus, pertussis (DTP), polio, Meningococcal C (Men C), Haemophilus influenzae type b (Hib)); first dose of measles, mumps and rubella (MMR); and pre-school childhood vaccinations (DTP, polio, MMR). We compared parental report with child health recorded MMR vaccination status at age three years.

Results

While 94% of children received the first dose of primary vaccines early or on time, this was lower for subsequent doses (82%, 65% and 88% for second and third doses and pre-school booster respectively). Median intervals between doses exceeded the recommended schedule for all but the first dose with marked variation between children. There was high concordance (97%) between parental reported and child health recorded MMR status.

Conclusions

Routine immunisation records provide useful information on timely receipt of vaccines and can be used to assess the quality of childhood vaccination programmes. Parental report of MMR vaccine status is reliable.

Project description:BackgroundChild survival is dependent on several factors including high vaccination coverage. Timely receipt of vaccines ensures optimal immune response to the vaccines. Yet timeliness is not usually emphasized in estimating population immunity. In addition to examining timeliness of the recommended Expanded Programme for Immunisation (EPI) vaccines, this paper identifies predictors of untimely vaccination among children aged 10 to 23 months in Kampala.MethodsIn addition to the household survey interview questions, additional data sources for variables included data collection of child's weight and length. Vaccination dates were obtained from child health cards. Timeliness of vaccinations were assessed with Kaplan-Meier time-to-event analysis for each vaccine based on the following time ranges (lowest-highest target age): BCG (birth-8 weeks), polio 0 (birth-4 weeks), three polio and three pentavalent vaccines (4 weeks-2 months; 8 weeks-4 months; 12 weeks-6 months) and measles vaccine (38 weeks-12 months). Cox regression analysis was used to identify factors associated with vaccination timeliness.ResultsAbout half of 821 children received all vaccines within the recommended time ranges (45.6%; 95% CI 39.8-51.2). Timely receipt of vaccinations was lowest for measles (67.5%; 95% CI 60.5-73.8) and highest for BCG vaccine (92.7%: 95% CI 88.1-95.6). For measles, 10.7% (95% CI 6.8-16.4) of the vaccinations were administered earlier than the recommended time. Vaccinations that were not received within the recommended age ranges were associated with increasing number of children per woman (adjusted hazard ratio (AHR); 1.84, 95% CI 1.29-2.64), non-delivery at health facilities (AHR 1.58, 95% CI 1.02-2.46), being unmarried (AHR 1.49, 95% CI 1.15-1.94) or being in the lowest wealth quintile (AHR 1.38, 95% CI 1.11-1.72).ConclusionsStrategies to improve vaccination practices among the poorest, single, multiparous women and among mothers who do not deliver at health facilities are necessary to improve timeliness of vaccinations.

Project description:BACKGROUND:Family planning (FP) needs among postpartum women in low- and middle-income countries remain largely unmet. Integrating FP with childhood immunisation services could partially reduce this unmet need by creating multiple opportunities for timely contact with FP services during the 12?months following childbirth. METHODS:A realist evaluation of an intervention integrating FP and childhood immunisation services in routine outreach clinics in two rural districts of Malawi was conducted. A Context-Mechanism-Outcome (CMO) framework was used to describe the drivers of the intervention. A detailed programme theory was developed based on the analysis of semi-structured interviews and focus group discussions with 50 stakeholders. RESULTS:A total of 9 core mechanisms were identified, which centred on constructs of access. Findings revealed that on the demand side, women were motivated to attend outreach clinics due to shorter travel distances; they felt confident they could access FP services and use contraceptive methods covertly if needed; and when supported by their husband, they were empowered to take up the use of contraceptive methods. On the supply side, providers were empowered through the training they received to provide integrated services; they were confident in their ability to provide essential services; and they were motivated by teamwork and by the recognition they received for their work. Additionally, some providers were found to be unwilling to walk long distances to reach remote clinics, which was seen to negatively affect the availability of services. CONCLUSIONS:The delivery of integrated FP and childhood immunisation services in the context of routine outreach clinics in rural Malawi was seen to trigger mechanisms of accessibility and to improve the acceptability and availability of FP services. However, further research is needed to understand how the integration of these services in a routine outreach clinic setting may affect other dimensions of accessibility, including the approachability, appropriateness and affordability of services.

Project description:BackgroundThe COVID-19 pandemic has disproportionately affected all essential healthcare services delivery in low-resource settings. This study aimed to explore the challenges and experiences of providers and users of childhood immunisation services in Nepal during the COVID-19 pandemic.MethodsSemi-structured qualitative interviews were conducted with childhood immunisation service providers and users (i.e., parents of children) from Kathmandu valley, Nepal. All interviews were conducted through phone or internet-based tools, such as Zoom, WhatsApp, and messenger. All interviews were audio-recorded, transcribed verbatim, and analysed using theme-based content analysis in an Excel spreadsheet.ResultsA total of 15 participants (n = 7 service providers and n = 8 service users) participated. Six themes were identified, namely: (1) impact of COVID-19 and lockdown on childhood immunisation services; (2) motivation and resilience for childhood immunisation; (3) Biosafety practices and Personal Protective Equipment (PPE) availability during the COVID-19 pandemic; (4) service adjustments and guidelines during pandemic; (5) availability of vaccines; and (6) immunisation program resilience in view of COVID-19. Service providers mentioned facing disruptions in services and some parents had decided to delay scheduled immunisation. However, most service providers showed determinations to deliver the services with high morale, while most service users reported taking their children for immunisation. Families migrating from urban to rural areas during the pandemic led to service providers having no means to confirm complete immunisation of migrating children. Service providers also experienced lack of adequate guidance to deal with the pandemic and personal protective equipment to protect themselves and service users.ConclusionDespite experiencing disruptions in childhood immunisation service due to the COVID-19 pandemic, service users and providers were determined to vaccinate the children. There is an urgent need for effective preparedness plans to be in place to address the observed barriers and to ensure resilient immunisation services during ongoing and future pandemics.
