Building a TB laboratory customer feedback system that improves care

A reliable feedback process gives tuberculosis laboratories a practical way to understand how clinicians, collection centres, patients, public health teams and referral partners experience their services. It can reveal delays, unclear reports, difficult sample requirements, communication gaps and barriers affecting access to testing.

For Australian laboratories, customer feedback should fit within existing quality management systems, privacy obligations and accreditation practices. Whether a service operates in Sydney, Melbourne, a regional centre or a remote setting, the aim is the same: collect useful information, turn it into improvements and show customers that their concerns lead to action.

Define the purpose and customer groups

Start by writing a short purpose statement. It might be to improve turnaround times for molecular and culture testing, make reports easier to interpret, strengthen communication about rejected specimens, or identify barriers faced by services sending samples across long distances. A clear purpose prevents the system from becoming a general complaints inbox with no defined outcome.

List every customer group that interacts with the TB laboratory. These may include respiratory physicians, infectious diseases teams, emergency departments, general practitioners, nurses, collection staff, hospital laboratories, public health units, patients and carers. In Australia, state and territory TB programs may depend on specialist laboratories and referral pathways, while rural and remote services may have different transport and communication needs from metropolitan hospitals.

Patients are important stakeholders even when they do not order tests directly. Their experience may include the clarity of collection instructions, the time taken to receive information, interpreter access and the way sensitive results are communicated. Aboriginal and Torres Strait Islander communities may also require engagement approaches that respect local community-controlled health services and established relationships.

The GLI Quality Tool can help laboratories connect feedback activities with its broader quality management roadmap. Its emphasis on quality systems essentials, documented processes, assessment and continual improvement provides a useful structure for making customer feedback part of routine laboratory governance.

Choose channels that people will actually use

Use several feedback channels rather than relying on a single online form. A brief survey can capture routine satisfaction, while interviews, telephone follow-up, incident reviews, service meetings and email comments can provide richer detail. A QR code on a test request guide may work well for hospital users, but a phone option is essential for customers who have limited internet access or prefer direct discussion.

Keep the initial survey short enough to complete in two or three minutes. Ask about a small number of measurable areas, such as ease of requesting a test, specimen instructions, communication, report clarity, turnaround time and overall service. Include one open text field for details, but avoid making long written responses the only way to provide feedback.

The best channel depends on the customer. A collection centre may prefer a monthly electronic survey, while a remote clinic may provide feedback during a scheduled phone call. Specialist clinicians in Brisbane or Perth may respond to a targeted service review, whereas busy emergency departments may need a single-click rating linked to a specific result or consultation.

Make the process visible. Add the feedback contact to reports, request forms, laboratory websites, service-level documents and customer newsletters. Explain that feedback can be positive, negative or neutral and that it will be reviewed for service improvement rather than used to assess individual clinicians.

Write questions that produce usable evidence

Questions should focus on observable parts of the service. Instead of asking whether a customer is “satisfied”, ask whether the result arrived within the expected timeframe, whether the report was easy to interpret, or whether staff explained the reason for a rejected specimen. These questions create information that can be linked to corrective and preventive action.

Use rating scales consistently, such as one to five, and define what the scores mean. A laboratory might treat a score of one or two as a trigger for review, while tracking the average score over time. Include “not applicable” where appropriate so customers are not forced to rate services they have not used.

Ask for essential context without collecting unnecessary personal information. Useful fields may include customer type, service location, test pathway and approximate date of contact. Avoid requesting a patient’s name, diagnosis or full clinical history through an unsecured survey. Feedback about a specific case should move to an approved confidential channel.

Include a question about priorities: “What one change would most improve this service?” This often produces more actionable information than several broad satisfaction questions. Review wording with a clinician, collection staff member and consumer representative before launch to check that it is clear, respectful and free from technical jargon.

Set up a safe review and response process

Document who receives feedback, who logs it and how quickly it is acknowledged. Routine comments may be entered into a quality register, while urgent concerns about patient safety, result interpretation, privacy or delayed notification should be escalated immediately under existing incident procedures.

Separate complaints from general comments, but connect both to improvement work. A complaint about a delayed result may indicate a transport problem, an instrument issue, a staffing gap or a communication failure. Classifying the underlying cause is more useful than simply recording that a customer was unhappy.

Protect confidentiality throughout the process. Limit access to identifiable feedback, store records in an approved system and remove personal details from reports used for team discussion. Australian laboratories should align the process with their privacy policies, health records obligations and NATA-related documentation expectations.

Set service standards for response. A simple approach might be to acknowledge feedback within two business days, provide an initial response within ten business days and advise the customer when a longer investigation is required. The response should explain what was found, what action will be taken and when the laboratory will review the result.

Turn feedback into improvement actions

A feedback system only earns trust when it leads to visible change. Review themes monthly or quarterly, depending on service volume. Look for repeated concerns rather than reacting to every isolated comment. Useful measures include response rate, complaint categories, median turnaround time, specimen rejection trends, report amendments and the proportion of actions completed by their due dates.

Use a structured improvement method such as Plan-Do-Study-Act. For example, if regional clinics report confusion about sputum packaging, the laboratory can revise the instructions, test the new version with several clinics, monitor rejection rates and adjust the process again. This keeps the response proportionate and evidence-based.

A cross-functional group can make the analysis stronger. Include laboratory scientists, specimen reception staff, pathologists, couriers, public health representatives and, where suitable, a consumer or community representative. The quality improvement team guidance offers relevant ideas for assigning roles, reviewing data and maintaining momentum.

Share outcomes with customers in plain language. A quarterly update might say that feedback led to revised request forms, clearer critical-result escalation instructions or an additional courier collection from a remote area. Closing the feedback loop demonstrates respect and encourages future participation.

Train staff to collect and respond professionally

Staff need to understand that feedback is part of quality work, not a personal criticism. Include the system in induction, refresher training and competency discussions. Explain how to invite comments, record information accurately, protect privacy and escalate concerns without arguing with the customer.

Role-play common situations. A nurse may report that a specimen was rejected without a clear explanation. A patient may be distressed about waiting for a result. A regional service may say that courier timing makes the published turnaround time unrealistic. Staff should know how to listen, acknowledge the issue, clarify facts and refer the matter to the right person.

Technical training also affects customer experience. If staff are learning to operate liquid culture systems such as MGIT, they need consistent procedures for specimen handling, quality control, result interpretation and communication. The staff training guide supports this part of the laboratory quality system.

Do not promise outcomes that staff cannot control. A professional response can acknowledge the impact, explain the next step and give a realistic timeframe. Supervisors should monitor whether staff feel safe reporting recurring service problems, because frontline observations often identify failures before survey data does.

Monitor performance and keep the system useful

Choose a small dashboard of indicators. It could include the number of feedback responses, response rate by customer group, average ratings, recurring themes, complaint resolution time and improvement actions closed. Compare results by location or service pathway carefully, since a small remote laboratory may have too few responses for meaningful statistical comparisons.

Review the feedback system itself at least annually. Check whether customers know it exists, whether the survey still reflects current services and whether the laboratory is receiving information from less vocal groups. Low response numbers may indicate that the form is too long, the language is unclear or customers doubt that anything will change.

Connect feedback findings with internal audits, external quality assessment, nonconformity reports, risk registers and management review. This creates a more complete view of performance. For example, repeated comments about late results may support audit findings about transport documentation or reinforce the case for a revised courier agreement.

Keep records of decisions, owners, deadlines and verification results. Once an improvement has been tested, confirm that it worked through a follow-up survey, a customer call, a turnaround-time measure or a reduction in rejected specimens. A feedback system becomes sustainable when evidence of improvement is as routine as evidence of testing quality.

Begin with one service pathway, such as sputum referrals from regional clinics, and run the process for a defined trial period. Invite customers to share their experience, review the findings with staff and publish the changes made. Then extend the approach across the laboratory so every voice—from a metropolitan hospital team to a remote health service—can help make TB testing safer, clearer and more responsive.
