Technical Implementation Details
Diagnosis-Specific Data Separation
The implementation maintains strict separation of patient data:
// Diagnosis-specific data retrieval (pseudocode)
async function getClientHealthData(clientId, options) {
// Get client's diagnosis information first
const clientDiagnoses = await getDiagnosesForClient(clientId);
// Filter health data based on diagnosis and specialties
const relevantLabTests = await getLabTestsForUser(
clientId,
{
specialtyArea: getSpecialtiesFromDiagnoses(clientDiagnoses),
...options
}
);
return {
diagnoses: clientDiagnoses,
labTests: relevantLabTests,
// Other relevant data similarly filtered
};
}Custom Health Metrics Visualization
The system implements specialized visualization components for different health metrics and conditions:
// Component for rheumatology metrics (pseudocode)
function RheumatologyMetricsChart({ patientId, timeRange }) {
// Fetch relevant inflammation markers
const { data, isLoading } = useQuery({
queryKey: ['/api/health/labs', patientId, 'rheumatology'],
queryFn: () => fetchLabsBySpecialty(patientId, 'rheumatology', timeRange)
});
if (isLoading) return <SkeletonLoader />;
// Transform data for visualization
const crpData = transformLabDataForChart(data.filter(lab => lab.testName === 'CRP'));
const wbcData = transformLabDataForChart(data.filter(lab => lab.testName === 'WBC'));
return (
<div className="metrics-container">
<h3>Inflammation Markers</h3>
<LineChart data={crpData} dataKey="value" nameKey="date" />
<LineChart data={wbcData} dataKey="value" nameKey="date" />
<LabValueTable data={data} referenceRanges={getReferenceRanges()} />
</div>
);
}Family-Client Data Management
The solution implements client selection and permission-based data filtering:
// Family member client selection (pseudocode)
function ClientSelector() {
const { user } = useAuth();
const {
selectedClient,
setSelectedClient,
availableClients
} = useClientStore();
useEffect(() => {
// Load available clients for this family member
if (user && user.role === 'family') {
fetchAvailableClients(user.id);
}
}, [user]);
return (
<Select
value={selectedClient?.id.toString()}
onValueChange={(value) => {
const client = availableClients.find(c => c.id.toString() === value);
setSelectedClient(client);
}}
>
{availableClients.map(client => (
<SelectItem key={client.id} value={client.id.toString()}>
{client.displayName}
</SelectItem>
))}
</Select>
);
