Series 1, Article 2 of 8 — Charity Data Analytics for ICB Commissioners

Why do ICB commissioners scrutinise health charity productivity?

Health charity productivity analytics are the metrics that answer the question commissioners are increasingly asking: given the workforce you employ and the funding you receive, how much useful clinical work is actually happening? Under the 2026 NHS Strategic Commissioning Framework, ICBs are expected to demonstrate value for every pound committed to the VCSE sector. That creates a direct line of accountability from commissioner to provider — and productivity data is the evidence trail that line runs along.

This is the second article in our eight-part series on charity data analytics for ICB commissioners. It covers the Productivity framework — clinician utilisation, caseload per WTE, and the advocacy and coordination workload that sits outside direct clinical contact. The first article covers performance KPIs: activity, demand, and access. Subsequent articles cover outcomes and PROMs, impact, equity, data quality, value for money, and the commissioner-ready dashboard.

What is clinician utilisation and how is it measured in a health charity?

Clinician utilisation is the proportion of a clinician’s contracted hours that are spent in direct client-facing activity — sessions, contacts, and structured interventions — as opposed to administration, training, supervision, travel, and unallocated time. It is expressed as a percentage: direct clinical hours divided by total contracted hours in the period.

For ICB commissioners, a utilisation rate in isolation means very little. What matters is the benchmark context. NHS community services typically target utilisation rates of 60–75% for clinical roles, recognising that supervision, case management, and documentation are necessary and non-negotiable. A charity reporting 90% utilisation is not necessarily high-performing — it may be under-supervising its staff or cutting corners on case management that will surface as quality problems later. A charity reporting 45% is not necessarily inefficient — it may be serving a complex caseload requiring intensive care coordination between contacts.

The productivity metrics that carry genuine analytical weight are not headline utilisation figures alone, but the relationship between utilisation, caseload, and outcome quality. Commissioners who understand this will ask for all three together.

Which productivity KPIs should health charities report to commissioners?

The productivity KPI set for commissioner reporting falls into three categories.

Workforce capacity metrics establish the denominator against which all activity is measured. Whole Time Equivalent (WTE) headcount by role, contracted hours per WTE per week, and available clinical hours after leave and training deductions give commissioners the capacity baseline. Without this baseline, every activity figure is uninterpretable — a charity reporting 500 sessions per month means something very different with 2 WTE than with 10.

Direct activity metrics measure what is happening within available clinical hours. Sessions delivered per WTE per month, contacts per WTE per week, and caseload per WTE at month-end are the core measures. These should be reported as a time series — not just the current period — so commissioners can see whether productivity is stable, improving, or under pressure. A declining sessions-per-WTE trend over six months is a signal worth investigating before it becomes a contractual issue.

Indirect activity metrics capture the work that sits between sessions but is essential to safe, effective service delivery. Did not attend (DNA) follow-up time, onward referral coordination, multi-agency liaison, and case review activity all consume clinical time that does not appear in session counts. Charities that omit this layer from their productivity reporting systematically understate their actual workload — and create a misleading impression of spare capacity that commissioners may act on.

What is the invisible workload and why does it matter to commissioners?

The invisible workload is the category of clinician time that does not map to a billable session or a recorded contact but is nonetheless essential to delivering the contracted service. In health charity settings, this typically includes advocacy on behalf of service users — housing applications, benefits assessments, safeguarding referrals — as well as care coordination with GPs, social workers, and secondary care teams, and the administrative overhead of maintaining compliant case records.

Commissioners cannot see this workload in standard activity reports, and that invisibility creates two problems. First, it leads to underestimates of the true resource requirement for a service — which in turn leads to underfunding in the next commissioning cycle. Second, it creates a false efficiency baseline. If a commissioner compares your sessions-per-WTE figure against an NHS community service that does not carry the same advocacy burden, your charity will appear less productive by a metric that does not measure the same thing.

The solution is not to argue against the comparison — it is to make the invisible workload visible. Charities that log advocacy time and coordination activity in their case management systems, and report it separately alongside direct clinical activity, give commissioners the evidence to understand the full service model. Those that do not are leaving a gap in the data that commissioners will fill with assumptions — and assumptions rarely favour the provider.

How should health charities structure their productivity reporting for ICBs?

A commissioner-ready productivity report should move from capacity to activity to efficiency in a logical sequence. Start with the workforce baseline — WTE headcount, contracted hours, and available clinical hours for the period. Then report direct clinical activity as sessions and contacts per WTE. Then layer in indirect activity — coordination hours, advocacy hours, and case management time — as a separate but connected figure. Finally, synthesise these into an overall productivity narrative: what is the total workload per WTE, and how does direct clinical time sit within that total?

This structure is only possible if your case management system captures time at the activity level — not just session counts. Charities whose systems record only appointment outcomes (attended, DNA, cancelled) but not the time spent on advocacy, liaison, and admin between appointments will find it impossible to report the full productivity picture. The data infrastructure question is therefore as important as the reporting question.

At Quematics, we work with health charities to build Power BI dashboards that draw from case management data to produce fully automated productivity reports — updated continuously, segmented by role and team, and formatted to meet ICB reporting expectations. For charities not yet at that point, our charity analytics team can audit your current data infrastructure and identify what changes are needed to make productivity reporting viable.

Frequently asked questions

What is a good clinician utilisation rate for a health charity?

There is no universal target, but a well-run community health charity should typically see direct clinical utilisation in the range of 55–70% of contracted hours. Below 55% warrants investigation of caseload management and scheduling efficiency. Above 75% sustained over several months may indicate insufficient supervision or documentation time, which creates clinical risk. The right benchmark also depends on role — a community keyworker carrying high advocacy responsibilities will have structurally lower clinical utilisation than a sessional therapist.

How do you calculate caseload per WTE for a health charity?

Caseload per WTE is the active caseload at month-end divided by the total clinical WTE delivering that caseload. It should be calculated at the team or service level — not aggregated across the whole organisation — to reflect the actual distribution of work. A caseload-per-WTE figure that appears sustainable at the organisational level can conceal significant imbalances at team level that create burnout and quality risk.

Should advocacy and coordination time be included in productivity reports to ICBs?

Yes — but separately from direct clinical time, not folded into it. Commissioners need to see both figures to understand the full service model. Combining them produces a blended utilisation rate that obscures the true clinical productivity picture. Reporting them separately — and being able to explain what the advocacy and coordination activity comprises — demonstrates analytical maturity and substantiates resource requirements in future commissioning negotiations.

What is the difference between WTE and headcount in charity workforce reporting?

Headcount is the total number of individuals employed or contracted. WTE (Whole Time Equivalent) normalises that figure to the equivalent of full-time working — typically 37.5 hours per week in NHS-aligned services. A charity employing four part-time clinicians each working 18.75 hours per week has a headcount of four but a WTE of two. Commissioners work in WTE because it is the only figure that allows meaningful comparison of activity and productivity across organisations with different staffing models.
