PRESS RELEASE: SA national health data overestimates immunisation coverage rates by up to 6 times

FOR IMMEDIATE RELEASE: TUESDAY 30th SEPTEMBER 2014, 00h00 CAPE TOWN

CAPE TOWN – Inaccurate data on South Africa’s national health information system means that the national database shows numbers up to 6 times higher than are recorded in corresponding facility registers, a new study published in the October issue of Strengthening Health Systems reveals.

The study, which involved authors from the Eastern Cape Department of Health and the University of Alberta, Canada, investigated the accuracy of nationally reported immunisation rates for children younger than 1 year in Eastern Cape Province, as reported on South Africa’s national health database – the District Health Information System.

By visiting a selection of facilities and counting numbers of children immunised as listed in facility records, then comparing these numbers with the database figures, the team calculated error rates for the data from each facility and sub-district. They then conducted a series of interviews with staff and district managers to find out why the data was not being managed correctly.

“We knew from an initial review of the national data that there were problems with the figures because five sub-districts reported that they had immunised more than 100% of the children in their catchment area – which is, of course, impossible,” explains lead-author Anne-Marie Jamin, University of Alberta, Canada, who supported the Eastern Cape Department of Health to investigate the issue.

“When we compared the database numbers with records at the facilities, we found surprisingly large differences between the national data and the records at facility level. One facility reported a 358% coverage rate when they had only recorded immunising 1.4% of the local children,” says Jamin.

According to authors, these findings show how the data management system is struggling to provide health managers and policy makers with the crucial information they need to do their jobs properly.

“If you looked at the reported figures alone, without knowing the error rates, you would think that the Province is doing really well on immunisation. What we found was that feasible-sounding district and provincial averages may actually be obscuring a significant problem, not only with data but also with the underlying public health campaign to expand immunisation,” explains Jamin. “Knowing more accurately where the problem areas are would help the Province target its work much more effectively.”

The authors recommend that the better training about data management processes in line with the national policy on health management information, better communication between programmes that deal with child health and improved systems for procuring registers for facilities could address the identified issues.
