Basta: Validitet i ett regionalt barnhälsovårdsregister
2011 (Swedish)Report (Other academic)
To validate a local Child Health Care Quality database (Basta) in the county of Uppsala, Sweden in terms of completeness and agreement with the Child Health Care record (CHCR).
Material and methods:
The target population for the study consisted of 2-year old children born during 2005 to 2008 and registered as residents in the county of Uppsala Sweden (n= 15 769), each child enrolled at one specific Child Health Centre (CHC, n= 41) in the county. The study population was determined by means of a two step cluster selection design. In step one 11 CHC: s was randomly selected. In step 2 five percent of the children at each of the 11 randomized CHC was randomly selected, the selection procedure ending up in a study population comprising 198 children. The CHCR for all 198 children was retrieved and information regarding visits at the CHC, home visits, participation in parenting group, parental smoking habits, breastfeeding and vaccination status was entered into the study database together with the corresponding data from the Basta database. The data on each pair of connected variables was compared and the results regarding the number of visits at CHC, the number of home visits, any home visit, a minimum number of 6 visits at CHC, a minimum number of 11 visits at CHC and participation in parenting group at any time were expressed as the percentage of correspondence. For results regarding if the child had received each dose of the recommended vaccines, breastfeeding status at given time points and paternal smoking at given time points the sensitivity, specificity and positive and negative predictive value between the CHCR and the corresponding Basta data was calculated.
The sensitivity value for given doses of vaccines against diphtheria, tetanus, whooping cough, polio myelitis and hemophilus influenza was > 95 % and for breastfeeding at 1 week, 2, 4 and 6 months of child age 94-95 %. The sensitivity value for maternal smoking was 100 % and for paternal smoking>90 %. For any home visit, participation in parenting group at any time, a minimum number of 6 visits at CHC and a minimum number of 11 visits at CHC the calculated sensitivity value were between 88 to 96 %. The sensitivity value for the exact match of number of visits at CHC was low. Increasing the tolerance to +/- 3 visits the sensitivity value was 88 %.
The results showed a satisfactory level of completeness in the Basta database and sufficient agreement with data in the CHCR. The data in Basta could be considered valid enough to be used for both the guarantee of quality and research purposes. However, some concerns could be made about using data on breastfeeding at 10 and 12 months and smoking status at 9 months where the attrition was higher and the exact number of visits at CHC where the exact match was low.
