HealthcarePHI
Protected Health Information. Under HIPAA, PHI is any information that can identify an individual and relates to their health condition, healthcare treatment, or payment for healthcare. This includes names, dates (except year), geographic identifiers, phone numbers, email addresses, medical record numbers, health plan numbers, and biometric data, when combined with health information. PHI includes both structured data (database records) and unstructured data (doctor's notes, images, audio recordings). Any software that stores, processes, or transmits PHI must implement HIPAA safeguards, and the vendor must sign a Business Associate Agreement (BAA).
HealthcarePrior Authorization
Prior authorization (PA) is the process by which a healthcare provider must obtain approval from a payer (insurance company or Medicare) before delivering a specific service, medication, or procedure. In home health, prior authorization is required for many skilled nursing visits and therapy episodes. The PA process involves submitting clinical documentation to the payer, receiving approval, and tracking authorization numbers and visit limits. Manually managing prior authorizations is a significant administrative burden for staffing agencies and home health providers. Purpose-built software automates PA tracking, expiry alerts, and documentation submission, reducing the risk of delivering unauthorized services that will not be reimbursed.
AI & AutomationPrompt Engineering
Prompt engineering is the practice of designing and optimizing the instructions given to a language model to produce more accurate, consistent, and useful outputs. Effective prompts specify the model's role, the expected output format, constraints on what the model should or should not say, and examples of correct behavior (few-shot prompting). In production systems, system prompts encode business rules ("never recommend a product not in the catalog," "always cite your source," "respond only in English") alongside persona and tone. Prompt engineering is valuable but has limits: it cannot reliably prevent hallucination on factual questions without RAG, and it cannot replace architectural safeguards in high-stakes environments.
MobilePush Notifications
Push notifications are messages delivered to a mobile device from a server, appearing as alerts even when the app is not open. On iOS, push notifications are delivered through APNs (Apple Push Notification service); on Android, through FCM (Firebase Cloud Messaging). For healthcare apps, push notifications must be designed carefully around HIPAA: notification content visible on the lock screen must not contain PHI unless the patient has explicitly consented. In home health, push notifications alert field clinicians to new patient assignments, care plan updates, and IDG meeting reminders. For e-commerce apps, they drive repeat purchases through order updates, back-in-stock alerts, and promotional campaigns.
Luxury RetailPre-owned Inventory Management
Pre-owned inventory management is the set of workflows a luxury retailer uses to handle used or vintage stock alongside new inventory: intake and condition grading, provenance verification, pricing that accounts for condition and market comparables, and sourcing-channel tracking (trade-in, consignment, or auction). It is operationally distinct from new-stock management because each piece is unique rather than a restockable SKU. A watch retailer running new, pre-owned, and mint-condition stock through the same generic inventory system loses the ability to see sourcing cost, condition, and provenance per item, which is exactly the gap Nexios built a purpose-specific CRM to close for a UK-based luxury retailer.
Luxury RetailProvenance Tracking
Provenance tracking is the recording of a luxury item’s ownership and authentication history: who owned it, where it was acquired, what documentation (papers, certificates, service records) accompanies it, and how its authenticity was verified. For high-value watches and jewellery, provenance is part of the item’s value, not administrative metadata. A luxury CRM needs to store provenance per serial-numbered piece and surface it at the point of sale, since a documented chain of custody is often what a buyer is paying for. Generic CRMs treat a sale as a deal between accounts; luxury retail treats it as a physical object with a life story that has to be tracked from acquisition through every subsequent sale.
