Tuberculosis

Tuberculosis (TB) has major health and social impacts for those affected. In addition, it contributes to increasing health inequalities in already deprived populations. Each infectious case represents a risk of onward transmission, and the failure to protect communities from TB transmission should be regarded as a failure of public health systems.[i]

Following major declines in the incidence of TB during most of the 20th century, the incidence of TB in England increased steadily from the late 1980s to 2005, and has remained at relatively high levels ever since.[i]

Reducing TB incidence is a key ambition of the Collaborative Tuberculosis Strategy for England 2015-2020[i] and an indicator of TB incidence is included in the Public Health Outcomes Framework.

Improving treatment and care services is also a key ambition; increasing the proportion of drug sensitive TB cases completing treatment within twelve months is a key indicator in the Public Health Outcomes Framework, while increasing the proportion of TB cases offered an HIV test is a key indicator in Public Health England's Sexual and Reproductive Health profiles.

Key findings for Lancashire-14

Incidence of TB, 2014-16 (1)

  • In Blackburn with Darwen (24.3) the three-year average incidence of TB per 100,000 population is worse than the England rate (10.9 per 100,000).
  • In Blackpool (10.3 per 100,000) the incidence of TB is similar to the England rate and in Lancashire-12 (5.5 per 100,000) it is better than the England rate.
  • There were 345 TB notifications across the Lancashire-14 area; 195 in Lancashire-12, 107 in Blackburn with Darwen and 43 in Blackpool.
  • Within Lancashire-12, in Preston (14.9 per 100,000) the incidence of TB is higher than the England rate.

TB treatment completion, 2015 (2)

  • In Lancashire-12 (80.8%) and Blackburn (87.5%) the proportion of drug-sensitive TB cases who had completed a full course of treatment by 12 months is similar to the England rate (83.4%); Blackpool's rate is not published by Public Health England.
  • Based on recent 11 years' trend, in Lancashire-12, the TB treatment completion rate is getting better.
  • Based on recent 15 years' trend, in Blackburn with Darwen, the TB treatment completion rate hasn’t significantly changed.

Proportion of TB cases offered a HIV test, 2016 (3)

  • In Lancashire-12 (89.2%) the proportion of TB cases offered a HIV test is significantly below the England rate (96.6%). However, a recent trend based on five years, shows that the proportion of TB cases offered an HIV test is increasing in Lancashire-12.
  • In Blackburn with Darwen (91.9%) the proportion of TB cases offered an HIV test is similar to the England rate; the recent trend, based on five years, shows that the proportion of TB cases offered an HIV test is increasing in Blackburn with Darwen. Blackpool's rate is not published by Public Health England.

(1) The number of reported new cases per year (based on case notification) per 100,000 population, 2014-2016

(2) The percentage of drug sensitive TB cases completing treatment for TB within 12 months, 2015

(3) The percentage of TB cases notified to Enhanced Tuberculosis System who were offered an HIV test (exclusions: TB cases where HIV status was already known and TB cases diagnosed post mortem).
