Attached are Tinnitus Hub's comments and the NICE response on the NICE Draft Guideline, Tinnitus: assessment and management. The Final Guideline has now been issued and can be found on the NICE website at the link in
@Hazel's post above.
In summary, Tinnitus Hub made 10 comments on the draft guideline. As a result of the comments NICE modified the Guideline as follows:
- included a recommendation that people with longstanding tinnitus who are seeking medical assistance for the first time be questioned about the reasons why they have not sought help in the past.
- added information about the impact of the loud noise of an MRI on tinnitus and need to dispense ear plugs into the rationale and impact for the imaging reviews and committee discussions in Evidence Reviews J and K.
- added information about the impact of tinnitus on sleep.
- added reference to the patient experience guideline which sets out broad principles in information provision to insure healthcare professionals are signposted to the most up to date information on tinnitus.
Comments from Tinnitus Hub that resulted in a response from NICE but no modification to the guideline can be summarized as follows:
- Tinnitus Hub commented on its experience and observation that management strategies, including psychological therapies, do not benefit the entire tinnitus population, particularly those with intrusive tinnitus. Therefore there is an urgent, unmet need for pharmacological or medical interventions for the treatment of tinnitus. Tinnitus Hub pointed out that tinnitus research is severely underfunded and that effective treatments leading to cures are needed.
- NICE responded that the committee decided to make research recommendations for management strategies as they can help people cope with their tinnitus irrespective of tinnitus severity. Lay members on the committee also expressed that the research recommendations will be beneficial for people with tinnitus. NICE goes onto say that they have made a recommendation for further research into neuromodulation, a key area that requires further research and that full details can be seen in Evidence Review O.
- Tinnitus Hub commented that healthcare professionals should provide an explanation of the various subtypes of tinnitus (subjective, objective, pulsatile, somatic, iatrogenic) but no reference or attempt to classify tinnitus is found in the guideline.
- NICE responded that apart from subtypes that can indicate a structural cause identifiable through imaging (ex, pulsatile tinnitus) sub-types based on perception were not considered a priority area to be included in the guideline.
- Tinnitus Hub commented that there is concern among its members that some anxiolytics and antidepressants or sleep medications may be ototoxic or have tinnitus as a side effect. More research and a guideline for prescribers is needed.
- NICE responded that this is an important issue, but is outside the scope of the guideline.
- Tinnitus Hub questioned the definition of sudden hearing loss and whether or not moderate or minor sudden hearing loss could cause tinnitus. Tinnitus Hub went on to assume that any type of hearing loss could benefit from medical intervention such as oral or intra-tympanic steroids and queried whether these interventions could be extended to include those moderate or mild hearing loss as well.
- NICE responded that the onset of sudden hearing loss is determined by the person telling the health professional the time in which it developed. This enables the healthcare professional to determine if its sudden or progressive. Sudden hearing loss is defined according to the time in which it developed, either over 3 days or less within the past 30 days or over 3 days or less more than 30 days ago. The recommendation applied to any kind of sudden hearing loss and the committee agrees that people should be seen for medical intervention as highlighted in the recommendations.
- Tinnitus Hub commented that the assessment of tinnitus include a detailed medical history and medical examination that includes offering blood test to ascertain is anaemia or diabetes is present.
- NICE responded that physical exam and clinical history is important, however, how these are done is outside the scope of the guideline so no recommendations can be made.
- Tinnitus Hub commented that a determination of whether TMD symptoms exist should be made.
- NICE responded that TMD was not identified as a priority for inclusion in the scope.
- Tinnitus Hub commented that the Secondary Care Assessment section does not refer to any test performed nor specify who the secondary care practitioner would be.
- NICE responded that people with tinnitus need to be referred based on their clinical presentation and local pathways. Recommending specific tests or details about roles of healthcare professionals is outside the scope of the guideline.
- Tinnitus Hub commented that anxiety and depression resulting from tinnitus requires tinnitus focused psychological interventions as per the suggestion made by NICE earlier in the guideline. Therefore specific guidelines for such focused interventions should be included rather than signposting to generic guidelines on anxiety and depression.
- NICE responded that since the section of the document in question is about psychological assessment, the committee did not think it appropriate to refer to recommendations on psychological therapies.
- Tinnitus Hub commented that although the guideline recommends people with tinnitus be asked about insomnia, no recommendations are made for addressing sleep problems.
- NICE responded that basic advice on sleep management should be provided as part of the information and support offered to people with tinnitus. Specific details on this are outside the scope of the guideline.
- Tinnitus Hub commented on the section of the guideline that speaks to Assessing How Tinnitus Affects Quality of Life. The comment stated that guidelines for teachers and employers would be welcomed.
- NICE responded that the guideline is intended to cover all settings where NHS-commissioned care is provided.
- Tinnitus Hub commented that an extended high frequency hearing test be administered to determine if the cause of tinnitus is due to hearing loss at higher frequencies than normally tested.
- NICE responded that no evidence was identified that evaluated the use of high frequency audiometry, therefore a recommendation could not be made.
- Tinnitus Hub commented that there is some evidence that hearing aids can be helpful for tinnitus patients with very minor hearing loss. Tinnitus Hub referenced the paper cited on BTA's website as support. Tinnitus Hub also requested further clarification about sound therapy.
- NICE responded that the paper cited (from BTA's website) was excluded from their consideration due to incorrect population and incorrect comparators. NICE went onto say there is insufficient evidence to recommend sound therapy and has recommended further research evaluating sound therapy with tinnitus support. The sound therapy component would include sound enrichment or masking.
- Tinnitus Hub commented that we agree with NICE that CBT and psychological therapies should be tinnitus focused and taylored to tinnitus patients and that it be more accessible.
- NICE responded that the committee noted that CBT could be delivered within different scenarios depending on whether tinnitus was the main issue or if co-existing anxiety and mood disorder were the main issues.
- Tinnitus Hub commented that hyperacusis assessment and treatment should be considered as part of the guideline.
- NICE responded that the guideline only applies to tinnitus and managing sound sensitivities such as hyperacusis were excluded. The committee have made a recommendation to make a management plan for those people with identified needs which would take into account other factors such as sound sensitivity.
OTHER
NICE did not respond to Tinnitus Hub comments made about the need for recommendations on safe noise levels and durations specifically for the tinnitus population.
NICE did not respond to Tinnitus Hub comments that tinnitus patients seldom receive a prognosis since there are no longitudinal studies that would inform on the natural history of the condition. Therefore, patient queries about whether tinnitus will worsen in time by getting louder, by the addition of more sounds, by spreading changing from unilateral to bilateral, etc., go unanswered. And, it has been the experience of some members of Tinnitus Talk that tinnitus worsens over time.
CONCLUSIONS
Issue Management - Early entry into the NICE process may have enabled better management of committee member perceptions about tinnitus severity and whether or not psychological treatments benefit all people with tinnitus. It may also avoid the subject of late stage comments being considered out of scope.
Landscape - NICE collected many comments from stakeholders, all of which are posted on their website. Reviewing these might give insight into stakeholder support for or against key issues which in turn might facilitate future interactions or predict responses of a given stakeholder should that issue arise once again. It might also help identify changes in thinking of a specific stakeholder.
Strength of the Evidence - As part of the process, the NICE committee reviewed many scientific publications about tinnitus. Cataloging these papers and NICE's decision to include or exclude the evidence along with any reasons given would be helpful for understanding the strength of the evidence for future responses to researchers or regulators.
