Healthcare Analytics Dashboard

Healthcare analytics in Power BI | KoderXpert

Healthcare analytics build · Power BI on encounters, diagnoses, prescriptions and procedures

The hospital recorded everything. It could report almost nothing.

the cost of not knowing is measured in readmissions

A multi specialty provider running ten clinical departments across outpatient, inpatient and emergency care. Every encounter, diagnosis, prescription and procedure was recorded. Clinically the record was complete; operationally it was silent. KoderXpert joined four record types into one clinical model and delivered four purpose built pages.

01 · Overview

Clinically complete. Operationally silent.

  • A multi specialty provider running ten clinical departments, from Cardiology and Neurology to Oncology, Nephrology and Pediatrics, across outpatient, inpatient and emergency care.
  • Every encounter, diagnosis, prescription and procedure was already recorded. Nobody could ask the record a question and get an answer the same day. In healthcare the cost of not knowing is measured in readmissions, delays and avoidable medication errors.
  • KoderXpert joined the four record types on shared department, patient and severity dimensions and built four pages: patient and encounter, clinical and diagnosis, medication safety, and procedures and workforce. Analysis is at cohort level throughout.

02 · The challenge

Each department reported for itself. Nobody counted the hospital.

The comparisons that expose a problem are exactly the ones a single department cannot produce, which is why none of them existed.

Each department reported for itself

Cardiology counted cardiology and Oncology counted Oncology. Length of stay and complication rates were never read side by side across specialties.

The cost → no comparison, so no outlier

Quality metrics compiled by hand

Readmission rate, length of stay and chronic disease load were assembled manually and periodically, by someone who could have been doing clinical work instead.

The cost → clinical time spent on spreadsheets

Medication safety was reactive

Errors, high risk prescriptions and antibiotic use were reviewed after an incident rather than monitored as a standing indicator.

The cost → a control that only worked in hindsight

Theatre and staffing ran on instinct

Procedure volumes, complication rates and surgeon coverage were felt rather than measured, so staffing conversations had no evidence base.

The cost → rosters argued, not evidenced

Four domains, four data shapes

Encounters, diagnoses, prescriptions and procedures each have their own grain. Forcing them into one model without double counting was the core technical problem.

The cost → any naive join inflates a patient

Patient level data, cohort level answers

The record is sensitive by default, so the model had to deliver insight without ever exposing an individual.

The cost → insight and exposure in tension

a readmission rate a clinician disputes is worse than none at all

04 · Goals

What the build had to achieve

Six goals set with clinicians rather than with administrators, because a number a clinician disputes discredits every number beside it.

One view of the whole hospital. Every department readable on the same measures, so the comparison that exposes a problem finally exists.

Outcomes, not just activity. Readmissions, severity and adverse outcomes rather than headcounts, because volume alone says nothing about care.

Medication safety as a standing metric. Errors and high risk scripts monitored continuously rather than investigated after an incident.

Throughput and capacity visible. Length of stay, delays and surgical load per specialty, as the input to any honest capacity conversation.

Clinically defensible definitions. Every rule agreed with the clinical side first, then encoded once, so the figure on the screen is the figure in the mortality and morbidity meeting.

Aggregate insight, protected patients. Analysis at cohort level throughout, never exposure at patient level.

05 · What we delivered

Four pages, four audiences, one model

Encounters, diagnoses, prescriptions and procedures describe the same patient from four angles. Kept apart they answer four narrow questions.

Block 01

Encounter overview

Total encounters, unique patients, average length of stay, readmission rate, total diagnoses and chronic disease share. The hospital's load and its outcomes on one line.

Block 02

Who is being treated, and how

Encounters by department, the outpatient, inpatient and emergency split, patient age bands and insurance mix. The demography behind the volume, which is what capacity planning needs.

Block 03

Discharge outcomes

Recovered, referred, against medical advice and deceased as proportions, so the outcome distribution is visible without a manual audit.

06 · Functional deep dive

How four record types become one model

Four decisions that decide whether a clinician will stand behind the number.

Four grains, one patient

An encounter, a diagnosis, a prescription and a procedure are four different grains. Joining them naively counts the same patient several times.

  • Each record type kept as its own fact at its own grain
  • Shared department, patient and severity dimensions across all four
  • Distinct counts over the patient dimension for anything patient level
  • Every measure tested against a single patient's full record

Clinical definitions agreed before coding

A readmission, a chronic case and an adverse outcome each needed a rule the clinicians would actually defend, not a rule that was convenient to compute.

  • Readmission window and exclusions settled with the clinical side
  • Chronic and critical defined against diagnosis categories, not free text
  • Each definition documented and handed over with the model

Safety as a monitored indicator

Errors and high risk prescriptions are the findings most likely to be buried by volume and most costly to miss, so they were given their own page rather than a tile.

  • Errors trended monthly rather than counted per incident
  • High risk and antibiotic scripts tracked as their own series
  • Repeat prescription patterns surfaced for governance review

Insight without exposure

Patient level records demand careful aggregation. The model was built so that no visual can resolve to an individual.

  • Cohort level aggregation enforced in the model, not just in the visuals
  • Small cohorts suppressed rather than displayed
  • Role based access aligned to clinical governance
Interactive 02

Complication rate against emergency share

a complication in an emergency is not the same finding

Every specialty plotted by how much of its work arrives as an emergency against its complication rate. The highest is picked out when you reach it. A high complication rate on a mostly emergency list is a different conversation from the same rate on an elective one, which is exactly why the two are read together.

07 · How we built it

Six stages from record to reading

The clinical KPI workshop came first, and everything downstream depended on it.

01

Clinical KPI workshop week one

Agreed with clinicians what a readmission, a chronic case and an adverse outcome actually mean, before any of them were coded.

02

Data modelling week two

Four record types unified on shared department, severity and patient dimensions, each kept at its own grain.

03

DAX development about ten days

Every outcome, safety and throughput measure built and unit checked, with distinct counts wherever a patient could otherwise be counted twice.

04

Dashboard design one week

Four pages, each led by a KPI strip and built around the questions its audience asks, from the ward to the board.

05

Clinical validation four days

Headline figures reconciled back to source records with the client's own clinical team, which is the step that makes the numbers defensible.

06

Deployment, training and tuning final week

Published with scheduled refresh, then walked clinical and administrative users through the drill paths and definitions and tuned against real usage.

08 · Engineering notes

What keeps clinical numbers defensible

In healthcare the technical risk and the clinical risk are the same risk: a number nobody trusts is worse than no number.

Distinct counts everywhere they matter

A patient with three diagnoses and two procedures must still be one patient. Almost every clinical double count comes from missing that.

  • Unique patients as a distinct count over the patient dimension
  • Encounter measures kept separate from patient measures
  • Each measure validated against a single full patient record

Definitions travelling with the model

The definitions document is part of the deliverable, because the model outlives the people who agreed it.

  • Every KPI has a written rule, an owner and a date
  • Changes to a definition version controlled rather than edited in place
  • The document handed over alongside the report

Governance and access

Clinical governance decides who may see what, and the model was built to that rather than retrofitted to it.

  • Role based access aligned to clinical governance
  • Small cohorts suppressed to prevent re-identification
  • No patient level drill through in any published page

Refresh and reconciliation

Scheduled refresh with headline figures reconciled back to the source records each run, so drift surfaces as a variance rather than as a dispute in a meeting.

  • Encounters, diagnoses and procedures checked on every refresh
  • Tolerances agreed with the clinical team
  • Failures visible on the page
Interactive 03

Medication safety, watched rather than reviewed

Medication errors by month, then high-risk prescriptions on the same axis. 2,284 errors existed as rows in a prescription table before this page; as a standing indicator they become a trend a governance committee can act on rather than an incident review after the fact.

11 · FAQ

Questions providers ask before commissioning a build like this

Each record type is kept as its own fact at its own grain, with shared department, patient and severity dimensions across all four. Anything patient level uses a distinct count over the patient dimension, and every measure was validated against a single patient's complete record before sign off.

Your clinicians, before anything is coded. A readmission window, what counts as chronic and what counts as an adverse outcome are clinical judgements, not technical ones. We facilitate the workshop, document each rule with an owner and a date, and hand that document over with the model.

No. Aggregation is enforced in the model rather than only in the visuals, small cohorts are suppressed to prevent re-identification, and no published page offers patient level drill through. Access is role based and aligned to your clinical governance.

Because errors and high risk prescriptions are the findings most likely to be buried by volume and most costly to miss. A metric that only surfaces during an incident review is not a safety control. Given its own page and trended monthly, it becomes one.

That is exactly why complication rate and emergency share are plotted together rather than separately. A complication in emergency surgery and one in an elective list are not the same finding, and comparing rates without the case mix behind them is how good departments get blamed for hard cases.

Any system that can expose encounters, diagnoses, prescriptions and procedures as extracts or through an API, including most HIS and EMR platforms. We read; we do not write back, and the clinical system is left untouched.

Usually daily, scheduled around when your clinical coding settles, since coding lag rather than technical capability sets the useful frequency. Where a department wants same day operational figures, the throughput measures can refresh more often than the coded clinical ones.

It surfaces immediately and it is worth surfacing. Uncoded encounters, diagnoses recorded as free text and procedures missing a specialty all appear as visible gaps in the first draft rather than being averaged away. We ship a data quality view so the numbers improve as coding improves.

They use it when the definitions are theirs, which is why the workshop comes first and why clinical validation is a named stage rather than a sign off. The four pages are built around what each audience asks, from the ward round to the board pack.

Six weeks was the shape of this one, with the KPI workshop and clinical validation taking a meaningful share of it. Fewer domains can be faster. More departments, multiple sites or a longer history extend it, and we scope that against your data.

Yes, and it is usually the strongest argument for building it. Once readmission, length of stay, complication and medication safety indicators are governed and reproducible, the reporting that governance committees and accreditation bodies require stops being a periodic manual exercise.

Because we model the four domains properly rather than building four reports, and because we start from clinical definitions rather than from a schema. We work across ERP, finance and operational data for clients in manufacturing, retail, healthcare and financial services. See our data analytics services or talk to a consultant.
