Abstract
LLORCA LAIA, Bort; OLLERO LAURA, Pérez and FAURA JAVIER, Soriano. The active search of patients improves vaccination coverage. Rev Pediatr Aten Primaria [online]. 2016, vol.18, n.70, pp.151-155. ISSN 1139-7632.
Objective:
improve vaccination coverage in the health center Fuensanta by actively seeking improperly vaccinated patients.
Material and methods:
design: single-blind clinical trial. Location: pediatric patients of health center Fuensanta. Participants: 736 patients, 401 in the intervention group and 335 in the control group. 28 patients who did not attend the CS in 24 months prior to the study and 2 refused to be vaccinated. Interventions: search active involvement of patients incorrectly vaccinated by telephone, letter and alarms in Computerized Medical Record and observation of vaccination status in the control group.
Main measurements:
variables: immunization status at the end of the study period; age; control group or the intervention group. Relative risk (RR), absolute risk reduction (ARR) and number needed to treat (NNT) was calculated. Results: overall improvement in the intervention group of 3.59 RR (95% CI: 2.07 to 6.22); RR 6.30 (95% CI: 1.72 to 23.10) at 3 years and RR 6.44 (95% CI: 1.38 to 29.96) at 6, with improvement, statistically not significant, at 14 (p 0.07), RR 2.22 (95 % CI: 0.90 to 5.43). Effect of active search at 3, 6 and 14: RRA 89.3% (95% CI 71.99 to 97.1) and NNT 1.11, RRA 81.1% (95% CI: 51.15 to 96, 01) and NNT 1.22; RRA 74.29% (95% CI 57.75 to 86.02) and NNT 1.33 respectively.
Conclusions:
The active search was effective at 3 and 6 years. At 14, the active search, not being statistically significant, improved immunization status prominently.
