01 — Problem & Framing

India's Dialysis Crisis: A System on the Verge of Collapse

The independent dialysis sector is caught in a perfect storm. While confronting a catastrophic treatment gap and soaring mortality rates, operators are simultaneously bleeding razor-thin margins through documentation failures, and buckling under the weight of archaic compliance reporting.

Crisis context: Visualizing the scale of the independent dialysis gap
97%
Treatment Gap

7.8M Indians need dialysis.
Fewer than 250,000 receive it.

100k+
Annual Deaths

Due to systemic failure, not lack of clinical tech.

45–55
Median Age

Patients are active breadwinners, compounding the economic cost.

What's Broken Operationally

📉

Documentation Gaps

Cost centers an estimated 8–15% of their total monthly revenue.

💸

Missed Billing

A 500-session/month center loses ₹75,000–1,50,000 every month.

PMNDP Rejections

Claims rejected due to incomplete records leave 3–4 months of cash outstanding.

🧩

Fragmented Tools

They use paper + WhatsApp + Excel — none of which talk to each other.

Why This Moment Specifically? (The Timing Is Right)

Phase 1: Post-COVID
The Paper System Broke

Dialysis centers stayed open during lockdowns. Staff attrition proved that reliance on human memory and paper registers caused near-miss clinical events. Operators became pull-motivated for digital systems.

Phase 2: ABDM & NABH
Regulatory Convergence

Simultaneous mandates for ABHA-linked digital records and constant audit-ready documentation forced digitization. Without it, centers actively lose insurance empanelments and private-pay credibility.

Phase 3: Current Goal
Clinical Operations Platform

To build the first clinical-grade, offline-capable setup that natively handles the complex workflows of Indian independent centers, without the overhead of massive enterprise software.

02 — Secondary Research

Haemodialysis: The Clinical Workflow

Haemodialysis is a procedure that replicates kidney function by removing waste products and excess fluid from the blood. The patient's blood is drawn through a needle or catheter, circulated through a dialyser (an artificial kidney membrane), cleaned against a carefully prepared dialysate solution, and returned to the body. A typical session runs 3–5 hours, three times per week, for the rest of the patient's life.

Clinical Immersion

To design an enterprise ecosystem for a zero-error clinical ward, secondary literature is only the starting point. I underwent firsthand clinical immersion at three active dialysis healthcare facilities, shadowing nurses in real-time. Direct field observations allowed us to witness the visceral, fast-paced reality of the clinic floor—unveiling critical bottlenecks, paper charting loops, and sudden patient complications that introduce invisible risks.

Actors

The dialysis patient sits at the centre of a tightly coupled care ecosystem. The Dialysis Nurse and Technician manage setup, monitoring, and teardown. The Nephrologist prescribes and adjusts treatment parameters. The Center Owner manages operations, staffing, and compliance — often with razor-thin margins.

Practices

The patient's treatment depends on a repeatable 3-session-per-week cadence, each requiring pre-session machine prep, intra-session monitoring, and post-session documentation. Handoffs between shifts are verbal or paper-based, creating systemic gaps in continuity that compound over months.

Information

Clinical data flows through fragmented channels — vitals on paper registers, prescriptions via WhatsApp, billing on Excel, and compliance reports manually assembled for NABH and insurance TPAs. No single system captures the full treatment picture, making audit readiness a perpetual scramble.

The ecosystem map reveals a system with many actors and touchpoints — but no digital connective tissue between any of them. To understand where the breakdown is most critical, the research zoomed into the frontline clinical journey: what actually happens, step by step, during a dialysis session. This is captured in the AS-IS Service Blueprint.

1.9 — Affinity Mapping

Affinity Mapping

43 raw observations from field visits, interviews, and secondary research were grouped into 8 clusters. Each cluster surfaces a distinct systemic failure pattern in the clinic's current way of working.

01 No Digital Records / Paper Dependency
All patient records are paper-based — no digital patient history
Blood work results not linked to any treatment record
Dry weight and fluid removal goal calculated manually every session
Dry weight data lives on paper — no alerts if outdated
Post-treatment BP and observations not recorded digitally — lost after session ends
Machine self-test result after disinfection not logged
Discharge summary not generated — patient leaves with no written record
No digital log of RO checks, machine self-tests, or maintenance history
No single patient profile that follows the patient across visits

Key Insight

The lack of a digital source of truth makes historical patient tracking impossible and severely limits continuity of care across sessions.

02 Memory-Dependent Processes
All prep steps depend entirely on staff memory — no checklist
Renolin/Pyroxy chemical wash sequence runs on staff memory
Strip test done manually — result not logged, no audit trail
Heparin timing and bolus administered from memory — no timer, no log
Alarm limits set manually each session — not standardised
BP threshold limits set manually each session — varies by nurse
Disinfection completion relies on nurse memory or verbal confirmation
Nurse handover between shifts passed verbally — nothing documented

Key Insight

Relying entirely on staff memory for safety-critical procedures leads to high cognitive load and a higher probability of protocol deviations.

03 No Alerts / No Real-Time Flags
If any RO test fails, machine will not run but staff may not know why
No alert if RO water quality drops mid-day
No alert if patient arrives without completing blood work
No alert if patient's weight gain since last session is dangerously high
If conductivity fails, dialysis stops but UF continues — nurse may not notice
NS line left open — no system check exists
Heat disinfection burn risk — no lockout or warning system
No escalation path if nurse is unsure during treatment

Key Insight

Without automated safety alerts and real-time flags, critical clinical anomalies go completely unnoticed until they manifest as patient complications.

04 Handover and Communication Gaps
No digital handover from triage nurse to treatment nurse — verbal only
No handover documentation if nurse shift changes mid-session
No nurse handover documentation between shifts
Head Nurse has no visibility into which machine or slot a patient is assigned to
No structured way to log mid-session events in real time
One nurse managing multiple patients — no prioritisation if multiple alarms fire

Key Insight

Fragmented, verbal-only communication channels between shifts and roles lead to disjointed patient management and lost clinical details.

05 Scheduling and Patient Flow
No digital scheduling — risk of double booking or missed slots
No patient history visible at time of booking
No confirmation sent to patient — missed appointments not tracked
No shift-wise slot capacity management — overbooking happens unknowingly
No waitlist system
First patient delayed daily — prep runs until 10–10:30am despite 8am start

Key Insight

Manual scheduling and lack of slot-capacity visibility lead to patient bottlenecks, long wait times, and delayed morning prep.

06 Billing and Consumable Tracking
Billing fully manual — calculated on patient weight not actual consumables
No automated record of consumables used per session
No billing software — no invoice, no payment record stored
Manual cash collection — no digital payment tracked against patient account

Key Insight

Manual billing based on assumptions rather than real-time consumable logs results in inventory shrinkage and revenue leakage.

07 Clinical Safety Risks
Nurse must not be distracted during line connection — no protocol enforced
NS line left open post-priming — dangerous for fluid-overloaded patients
Conductivity fail — fluid removed but dialysis not happening, nurse may not notice
Turnaround between patients frequently rushed — disinfection sometimes incomplete
Stock management informal — no tracking of consumables remaining
No incident reporting system — near-misses never recorded, patterns never identified

Key Insight

The absence of strict, system-enforced safety protocols increases the risk of cross-contamination and critical treatment errors.

08 Admin and Facility Oversight
No digital log of RO checks, maintenance history — no audit trail
No preventive maintenance schedule — done reactively after breakdown
No dashboard for admin or owner — patient load, revenue, stock all invisible
Stock management entirely informal
No single patient profile across visits
No escalation path documented

Key Insight

A complete operational data blind spot prevents facility administrators from planning preventive maintenance, tracking audits, or optimizing costs.

Problem Definition

Problem Statement

To define a clear focus for design intervention, the 8 key insights were synthesized and mapped to identify a common, underlying systemic failure theme. This gave rise to the central problem statement:

Small independent dialysis clinics in India have no shared digital infrastructure — forcing nurses, head nurse, and owners to manage life-critical workflows entirely through memory, paper, and verbal communication, making safety incidents invisible, operations unreliable, and the business impossible to run with any real visibility.

1.10 — Jobs to be Done

What People Are Really Trying to Accomplish

The JTBD framework strips away features and asks: what is the person trying to make happen in their life? What does 'done' look like for them? This framing produces more durable design decisions because it anchors to human goals, not technology.

Opportunity Areas

Guiding Opportunity Areas: How Might We?

To transition from synthesis to active design exploration, the core friction points were reframed into actionable design questions. These 6 key How Might We (HMW) statements guided our ideation phase, ensuring every feature directly solved a validated operational pain point.

How might we make every critical clinical step self-documenting, so that no action depends on a nurse's memory and no event is ever lost between shifts?

How might we give every nurse a complete and current picture of each patient at any point in the journey, without having to ask anyone or search through paper?

How might we make clinical safety proactive rather than reactive, so that dangerous deviations are flagged before they reach the patient rather than noticed after?

How might we give the clinic a structured start to every day, so that slots, machines, and prep are aligned before the first patient walks in?

How might we make every session automatically generate its own financial record, so that billing reflects what actually happened and the owner always knows where the business stands?

How might we surface patterns from daily clinical and operational data, so that the facility owner can make decisions based on evidence rather than gut feel or verbal updates?

The Vision

Proposed Solution

A clinical operations ecosystem for independent dialysis clinics — comprising a mobile app for nurses that guides treatment workflows, builds patient records in the background, and auto-generates handover summaries; and a desktop dashboard for reception and admin that manages slot booking, billing, consumable tracking, and facility oversight — replacing institutional memory with institutional systems across every role in the clinic.
Project Scope

For this project, the primary design output is the nurse-facing mobile application. The desktop dashboard for reception and admin is defined at the feature and information architecture level but not taken to wireframes.

Nurse Cognitive Mapping

Cognitive Task Analysis — What the Nurse Holds in Her Head

During an active session, a dialysis nurse is bombarded with several critical tasks, for several patients with varying needs and with no margin of error. The cognitive load on the nurse can be understood better through the session map of memory load, divided attention and invisible risk for Sunita, the dialysis nurse's persona.

Theme Summary — Translating Research to Design

Memory recall

1 4 5 6 9 10

Nurse performs 6 distinct memory recall tasks per session with no digital reference. Each is a potential error.

Design Implication

Every recalled value needs a digital prompt or pre-loaded reference

Mental calculation

2

Fluid removal goal calculated mentally every session under time pressure with incomplete paper data.

Design Implication

Calculation should be automated — input current weight, system outputs safe removal target

Divided attention

8

Precision clinical task performed while simultaneously managing patient interaction. No protocol protects focus.

Design Implication

System should enforce a mandatory focus window during line connection — no interruptions

Invisible risk

3 7 12

Dangerous conditions exist but no system flags them. Nurse must notice manually while managing other patients.

Design Implication

Threshold-based alerts needed for weight gain and conductivity — system detects, nurse responds

Decision under uncertainty

11 13

Nurse has a reading but no baseline to judge it against. Cannot determine severity without history she does not have.

Design Implication

Every reading needs automatic comparison to patient baseline and previous session data

Information Architecture

Structuring the Connected Clinic App

The information architecture focuses on mobile app navigation based on sessions created on a primary HMS. It is structured around clean data relationships, rapid-access modules, and clear state hierarchies.

Wireframes & Iterations

Design Wireframes and Iterations

Through user testing and clinical feedback, I refined the iterations based on clinical ease and system status.

Task Dashboard

The homepage is a summary of all the tasks that a nurse has to do for multiple patients. At any point, the most immediate tasks the nurse must perform for various patients are arranged based on time.

Task Dashboard wireframe showing task summaries arranged by timeline

Active Session

During an active session, the hardest challenge was understanding hierarchy of information and states. The Cognitive task analysis helped break down this challenge into digestible sections.

Active Session UI wireframe showing visual hierarchy and critical clinical states

Shift Handover

Shift handover is usually the most critical stage at a dialysis clinic where miscommunication can lead to disruptions in quality treatment. To overcome the same, I designed in order to reduce cognitive load and ensuring that the patient's charting is legible as well as the remaining tasks for a particular patient's dialysis can be easily taken over by the next nurse on duty.

Shift Handover wireframe showing patient charting legibility and handover task checklist

Checklists and Inputs

During a single dialysis session of 4hrs, a nurse might have 25+ tasks. This becomes a mountain of cognitive load due to multiple patients being under care of a single nurse. To overcome this, I broke down the tasks into checklists, inputs and tracking.

Reflection

What Worked & What I'd Do Differently

Key takeaways, strategic decisions, and lessons learned for future clinical iterations.

Research-first design

Starting with nurse interviews and CTA analysis meant every design decision was grounded in real clinical problems, not assumptions.

Involve nurses earlier in iteration

I evolved designs based on clinical immersion, but early feedback from actual nurses would have caught things we missed.

Simplification over feature-creep

Focusing on 3 core tasks (BP, Heparin, Weight) instead of trying to digitize everything made the app actually usable in a chaotic environment.

Prototype the emergency scenario

The Critical BP Alert is important, but we didn't test how a nurse would react to it in real conditions.

Real-world constraints

Designing for machines that aren't connected forced me to think about realistic workflows, not ideal-state technology.

Design for global scenario

In several countries, dialysers directly produce partial medical charting based on the parameters the dialyser notes. Thus, designing for such scenarios would help develop a global acumen.

In Indian dialysis clinics, thousands of nurses manage patient safety with paper notes and memory. This system proves that thoughtful design for constrained environments can transform care quality.

If this were deployed across even 100 clinics, it could prevent hundreds of medication errors and improve documentation for tens of thousands of patients.

This app solves one problem: it turns a nurse's mental load into system design. Everything else follows from that.
