Background: Cambodia has a high burden of Tuberculosis (TB) with an incidence rate of 326 per 100,000 population in 2018 and rapidly increasing rates of Diabetes Mellitus (DM) with prevalence rate 9.6% in 2016. The introduction of the first national guidelines for the management of TB/DM co-morbidity in 2014 has resulted in the introduction of coordinated service delivery.

Objective: This study aimed to assess the performance and the results of bidirectional TB/DM screening, diagnosis of co-morbidity, and enrollment in treatment in 7 health operational districts in 5 provinces in Cambodia.

Methods: The retrospective study reviewed patient records of 6,463 DM patients and 8,403 TB patients who received treatment between July 2016 and February 2019 in 7 referral hospitals and 113 health centers.

Results: Forty percent of DM patients were screened for TB, and 55% of TB patients were screened for DM. Of the screened DM patients, 4.6% were diagnosed with TB. Of screened TB patients, 3.7% were diagnosed with DM. All DM patients diagnosed with TB were enrolled in TB treatment and 95% of TB patients diagnosed with DM began receiving treatment for DM.

Conclusion: This is the first study examining TB/DM co-morbidity and coordinated service delivery in Cambodia. The gaps in the performance of bidirectional screening suggest areas for further intervention. To increase the rate of bidirectional screening, provider compliance with standards needs to be improved by strengthening providers competencies. Strengthened data collection and reporting systems will also contribute to increasing provider accountability. Secondly, the current structure of TB and DM service delivery with TB services only available from the public sector and public DM services only available at the referral level creates a challenging environment for effective referrals and coordinated care and should be reconsidered. In addition to improved coordination between the public and private sectors, expansion of public DM services to health centers and to the community level warrants exploration. Finally, the increased focus needs to be given to addressing the high levels of pre-diabetes. Cambodia has a limited window of opportunity to build capacity and develop systems to effectively manage TB/DM co-morbidity.
