Module 1. Health systems through a GI lens. The WHO building blocks, UHC, and how an IBD or hepatitis service depends on all of them.

Six building blocks, three goals. The WHO framework describes a health system by six building blocks: service delivery, health workforce, health information systems, access to essential medical products and technologies, financing, and leadership and governance. These work together toward goals of improved health, responsiveness, financial protection and efficiency. A weakness in one block limits what the others can achieve, which is why single-programme fixes often disappoint.

Universal health coverage. UHC has three dimensions: who is covered (population), which services are covered (benefit package), and how much of the cost is covered (financial protection). Moving along one dimension often tests the others. Expanding the benefit package without more money increases waiting times or out-of-pocket payments. Policy choices about which services to include are, in practice, choices about trade-offs between these dimensions.

Roles in the Saudi system, simplified. Under Vision 2030 the Health Sector Transformation Program aims to separate roles that were once combined: regulator, payer and provider. The Ministry of Health sets policy and regulates, health clusters organise care for defined populations, and a holding company structure supports the public provider network. Separate bodies handle drug and device regulation (SFDA), workforce standards (SCFHS), insurance regulation (CCHI) and accreditation (CBAHI). Public health functions sit with the Public Health Authority. Mandates evolve, so check current sources before citing roles.

A worked example. An IBD service can have good biologics supply (medical products), yet long delays because the workforce lacks IBD nurses (workforce), no registry to see who is lost to follow-up (information) and no payment for multidisciplinary clinics (financing). The weakest block, not the strongest, sets the performance.

Module 2. The policy process, actors and power. Agenda setting, the policy triangle, stakeholder mapping, and why good evidence is not enough.

The policy cycle, and its limits. A useful simplification: agenda setting, policy formulation, adoption, implementation, then evaluation, which feeds back to the agenda. Real policy is messier, with stages overlapping and loops back, but the cycle is a good checklist of what might be missing. Many policies fail not at formulation but at implementation, where nobody planned who would do what, with what money.

Context, content, process, actors. The Walt–Gilson policy triangle asks four questions. Context: what social, economic and political conditions shape the policy? Content: what exactly is proposed? Process: how does an issue get on the agenda and move through decision stages? Actors: who has a stake and what power do they hold? Analysing only content, as technical experts tend to do, misses most of why policies succeed or fail.

Stakeholder mapping and policy windows. Map stakeholders on two axes, interest and influence. High-interest, high-influence actors need close engagement; low-interest, low-influence actors need only information. Kingdon’s multiple-streams idea says a policy window opens when three streams meet: a problem becomes salient, a workable solution exists, and the political climate favours action. Prepared advocates keep solutions ready for when the window opens.

A worked example. A national policy to add FIT-based colorectal cancer screening to the primary care package: agenda (rising CRC incidence at younger ages), formulation (age bands, test, pathway), adoption (cabinet or ministerial approval), implementation (invitations, labs, colonoscopy capacity), evaluation (uptake, positivity, stage at diagnosis).

Module 3. Evidence, data and indicators for policy. Choosing indicators, reading care cascades, and being honest about uncertainty.

Structure, process, outcome. Donabedian’s framework separates what a system has (structure: staff, equipment, beds), what it does (process: wait times, guideline adherence) and what results (outcome: survival, complications, stage at diagnosis). Good dashboards use all three and keep a few well-defined indicators rather than dozens. Process indicators move first and are easier to act on; outcome indicators matter most but lag.

The care cascade. A cascade lists the steps patients must pass through, with numbers at each: eligible, invited, tested, positive, linked to care, treated, cured. The biggest drop-off is where action pays most. Cascades are the standard tool for programmes such as hepatitis C elimination, where WHO global targets for 2030 include diagnosing 90% of infected people and treating 80% of those eligible.

Uncertainty and what policymakers can use. Policymakers need clear messages but not false certainty. Give a best estimate with a range, say how sure you are and why, and say what would change the conclusion. Distinguish what the evidence shows (an effect), what is modelled (a projection) and what is judged (a value). Data limitations should be stated early, with a plan to improve them, rather than hidden.

A worked example. Colonoscopy: structure is the number of endoscopists and rooms. Process includes waiting time for a positive FIT, caecal intubation rate, adenoma detection rate and bowel-preparation adequacy. Outcomes include interval cancer rate and stage at diagnosis.

Module 4. Health financing, insurance and purchasing. Raising, pooling and spending money, with payment methods for endoscopy and biologics.

Collect, pool, purchase. Health financing has three functions. Revenue collection raises funds from taxes, insurance contributions or direct payments. Pooling combines funds so risk is shared across many people. Purchasing uses the pool to buy services, ideally strategically, linking payment to need, quality and value. Financial protection improves as the share of spending from pooled sources rises and out-of-pocket payments fall.

How providers are paid shapes what they do. Fee-for-service rewards volume and can lead to over-use. Capitation pays per enrolled person and rewards prevention but can encourage under-provision. Diagnosis-related groups pay per case type and reward efficiency, with a risk of early discharge or selecting simpler cases. Bundled and outcome-linked payments pay for an episode or result. No method is perfect; the best systems blend them and monitor for gaming.

Strategic purchasing, out-of-pocket spending and equity. Strategic purchasing asks what to buy, from whom, at what price, and for whom, using evidence including HTA. Out-of-pocket spending is the weakest form of financing for protection and equity. A household is commonly considered to face catastrophic spending when out-of-pocket health payments exceed 10% of its budget, one of the thresholds used in SDG indicator 3.8.2. In the private sector, mandatory cooperative insurance, regulated by CCHI, covers employees; benefit design and co-payments decide what remains out of pocket.

A worked example. A patient with Crohn’s disease needing biologic therapy faces a cost that no household can predict. Pooled funding (tax or insurance) turns an unpredictable catastrophe into a predictable premium. Without pooling, treatment depends on ability to pay.

Module 5. Regulation, governance and data. Who sets the rules for products, people, facilities and data, with endoscopy as the running example.

Regulatory functions and who performs them. Health regulation covers products (drugs and devices), people (workforce standards), places (facility licensing and accreditation), payers (insurance rules) and data (privacy and sharing). In Saudi Arabia these functions are assigned to different bodies, such as SFDA for drugs and devices, SCFHS for health professionals, CCHI for cooperative insurance, and CBAHI for accreditation, while data use is governed by the Personal Data Protection Law (PDPL) and health-sector rules. The exact boundaries evolve, so confirm current mandates for any formal use.

Instruments: licensing, standards, incentives, information. Regulators have a menu of instruments. Licensing and credentialing set minimum entry requirements. Standards and accreditation set expected processes. Incentives, such as payment tied to quality, reward desired behaviour. Information, such as public reporting, lets patients and purchasers compare. Choosing between them depends on the problem: a safety hazard may need a mandatory standard; a performance gap may respond to feedback and incentives.

Transparency, conflicts of interest and registry governance. Decision bodies earn trust through declared interests, recorded reasons and published outcomes. Registries need clear governance: a defined purpose, a data controller, patient information and consent or a lawful basis, security, rules for access and sharing, and a plan for retention and deletion. Without this, a useful registry becomes a liability.

A worked example. A new capsule endoscopy system needs SFDA device clearance; the operators need credentialing recognised by the professional body; the hospital unit must meet licensing and accreditation standards; and image storage must satisfy data protection rules.

Module 6. Strategic planning for GI services. From environmental scan to capacity, wait times, workforce and a measurable plan.

Scan, goals and indicators. A plan starts by understanding the context: population need, current capacity, workforce, finance, partners and policy direction. Goals follow, written so they can be checked: what will change, by how much, by when, who owns it and how it will be measured. Vague goals (“improve access”) cannot be monitored. Each goal needs one or two indicators and a baseline.

Queues, capacity and the backlog. A waiting list behaves like a queue. If referrals arrive faster than the service can treat them, the backlog grows every week. The average wait is roughly the backlog divided by weekly capacity. To reduce waits, a service must have a positive surplus (capacity minus demand) or must cut demand. A one-off extra effort without more capacity clears a backlog once, but it returns.

Levers and trade-offs. Waiting-list policy has three families of levers: add capacity (sessions, staff, rooms, extended hours), reduce inappropriate demand (triage using FIT or calprotectin, appropriate-use criteria, primary care protocols) and improve flow (pre-assessment, bowel-preparation support, reducing no-shows). Each has costs and risks. Triage lowers demand but needs primary-care capability; added sessions cost money and need staff; no-show reduction works only if patients are reachable.

A worked example. Goal: reduce median wait for routine colonoscopy from 18 weeks to 8 weeks within 12 months, owned by the cluster endoscopy lead, measured monthly from the booking system. Baseline: 18 weeks (current audit).

Module 7. Policy communication and advocacy. Writing a policy brief, making the economic case, and engaging decision-makers.

The policy brief. A policy brief is short (two to four pages), standalone, and written for a busy reader. A typical structure follows the WHO EMRO template: title and key messages; the problem and why it matters now; the options with their pros and cons; a recommended option; implementation considerations; and a one-line ask. Lead with the conclusion, use plain words, avoid jargon, and put detail in annexes.

Making the economic case. Decision-makers ask what it costs and what they get. A benefit–cost ratio (BCR) compares the present value of benefits with the present value of costs. For prevention and screening, benefits arrive years after costs, so the lag matters. Be explicit about the lag, discount rate and what is counted. A BCR above 1 means benefits exceed costs, but a ratio near 1 with a long lag is a hard sell. Report assumptions and a range.

Audience, channel and crisis communication. Different audiences need different messages. A minister needs a decision and a headline number; a finance officer needs cost and risk; clinicians need clinical credibility; the public needs clear action. Choose the channel to match: brief and meeting for decision-makers; press release and media interviews for the public; social media for reach, with accuracy first. In a crisis, be first, be accurate, be consistent, acknowledge uncertainty, and say what people should do.

A worked example. Brief on hepatitis C elimination. Key message: “Treat everyone diagnosed within 12 weeks.” Problem: half of those diagnosed are untreated. Options: status quo, treatment hubs in clusters, primary care prescribing. Recommendation: hubs plus training. Ask: approve pilot funding for three clusters.

Module 8. Equity, ethics and implementation. Measuring inequity, choosing under scarcity, and making policy work on the ground.

Measuring equity. Inequity is a difference in health or access that is avoidable and unfair. To manage it, measure it: compare an indicator across groups (region, income, sex, nationality) using the rate difference (absolute gap) and the rate ratio (relative gap). Report both. A small relative gap in a common outcome can be a large absolute burden, while a large relative gap in a rare outcome can be a small absolute burden.

Choosing under scarcity: screening and priorities. Wilson and Jungner’s 1968 principles remain the standard checklist for screening: an important health problem, an accepted treatment, facilities for diagnosis and treatment, a recognisable early stage, a suitable test acceptable to the population, an understood natural history, an agreed policy on whom to treat, cost balanced against the benefit, and continuing case-finding. Priority-setting under scarcity should be explicit, using criteria such as burden, effectiveness, cost, equity and feasibility, and should be open to challenge.

Implementation and learning. Policies work when people can do what the policy asks. Implementation frameworks such as CFIR list domains to examine: the intervention itself, the outer setting, the inner setting, the people involved and the process. Typical barriers are workload, unclear roles, lack of training, weak data systems and misaligned incentives. Match strategies to barriers (training, protocols, reminders, feedback, payment changes) and monitor early, with a clear decision rule for adapting or stopping.

A worked example. FIT screening uptake is 52% in urban areas and 31% in remote areas. Rate difference 21 percentage points; rate ratio 1.68. If remote eligible adults number 200,000, closing the gap would add 42,000 people screened.
