HIV, STIs, Viral Hepatitis and LTBI Routine Screening Toolkit: Testing and diagnosis

A lack of a clear protocol for testing, compounded by an overwhelming demand for care, causes staff roles to blur and leaves the bulk of the workflow on the clinician’s shoulders, including obtaining consent, disclosing results, counseling and coordinating follow-up care.

Some clinicians and staff may also feel intimidated by interpreting results and next steps for the inconclusive test results. For LTBI, the interpretation of the IGRA can often be difficult for clinicians who do not specialize in infectious disease. For HIV, clinicians are often unaware what the next step is upon a positive diagnosis. Providing education on the latest evidence-based guidance for screening, testing and treatment can instill confidence in the care team and provide a more personal approach to address the patient’s needs. 

Additionally, many STI screenings clinics have merged into one model with family planning clinics or general community health centers. This has resulted in staff shortages and community health center care team members taking on multiple responsibilities beyond their core roles. Employing task shifting techniques, defining a routine testing plan streamlined by EHR support, outlining a clear post-test protocol and clarifying team member roles can help incorporate routine screening more seamlessly into standard workflows.

• Screening guideline ambiguity and the need for clarity for all test result scenarios and who to notify and when to notify them 
• Health care professional discomfort with screening and diagnosis for LTBI: fear of transmission (latent vs. active TB); confusion about screening guidelines and what tests to use, how to treat (historically, this used to be the responsibility of the local public health agency)
• Education on interpreting results and next steps for inconclusive/indeterminate results
• Staffing shortages due to financial limitations and consolidation of clinics 
• Lack of space to ensure patient privacy
• Lack of on-site equipment and reliance on external labs 
• Desire from patients to know results right away is at odds with testing logistics and can lead to loss of contact with the patient before results are complete 
• Pressure to meet other funder-driven requirements in addition to patient’s chief reason for visit 
• Knowledge and awareness of the appropriate CPT codes 
• STD tests sometimes run into insurance denials based on diagnostic codes

1. Streamline the testing cascade

   1. Optimizing the clinical workflow can help to streamline testing, clarify roles and ensure clinic staff know what happens at each step along the way. Also, leveraging testing innovations like rapid antibody test technologies or Reflex RNA for HCV allows for faster detection through the ability to immediately run another lab test on the same blood draw so that patients do not have to return for additional testing, allows for quicker delivery of results to patients. Clear guidance on testing interpretation and result sharing, in accordance with applicable privacy laws, will help reduce the cognitive load for health care professionals who are juggling a positive diagnosis with other immediate clinical needs. Strong relationships with local health departments (in particular, disease surveillance units) can also enable clinical staff members to rapidly identify which patients are experiencing a diagnosis for the first time, or who need reengagement in medical care.

2. Train care team members to task-shift 

   1. Shifting routine screening duties to nurses and medical assistants can answer the patient’s need for a personal approach and ensure clinical and non-clinical tasks are distributed efficiently and effectively.

3. Outline funding and reimbursement strategies

   1. Breaking down direct and indirect costs for each element of routine screening and testing, across the health setting’s payer mix, will help identify gaps in funding and reimbursement and uncover opportunities for negotiation. Budgeting EHR development, equipment, the cost of tests and staff time for routine screenings will eliminate unknowns and inspire confidence. Additionally, ensuring you are coding services properly for eligible patients will ensure you are reimbursed for the cost of the service and that the patient will not have any out-of-pocket costs.
