  • Although all cuffs were wearing out.

Cuffs for electronic machines provided to all clinics
July 2014 to March 2015
  • Cuffs for manual machines were still a problem.

  • Electronic machines themselves began to develop problems as a result of overuse.

  • Little information in this period

April 2015 to August 2015
  • Problems with the electronic BP machines increased (with the on/off button not working, or the machine not clearing the data in preparation for the next patient).

  • At the end of the period three of the four intervention clinics had their machines sent for repair.

  • Clinic managers had little hope of getting them back soon.

  • Cuffs supplied by study had started wearing out.

  • Early in this phase one clinic sent its machines for servicing, but it was not returned by the end of study.

  • Two clinics doubted the accuracy of readings and used a manual machine to confirm a high reading.

  • Cuffs supplied by study had started wearing out.

  • BP, blood pressure.
