Rx.Luxury: a patient’s desk that keeps your data at home

What it is, and who it is for

Rx.Luxury is a personal clinical desk that runs in the browser: intake notes, symptoms, medications, vitals, a printable visit packet and a viewer for DICOM scan files. Beside it sit two live US directories — clinicians from the federal NPI Registry, and every Medicare-certified hospital with its CMS overall rating where CMS publishes one.

It is for patients and carers in the United States who want their own notes in one place, a tidy packet to take to an appointment, a look at their own scans, and clinicians and hospitals from the official registers rather than an advertiser’s list.

How it works

Your side of the desk stays in your browser. State lives in localStorage (app.js lines 64–73); the PDF and ZIP exports are written by hand in save.js, so no outside library is fetched (lines 1–13); scans are parsed locally by a bundled dicom-parser 1.8.21 and drawn with window presets for brain, bone, lung and soft tissue (dicom.js lines 1–25). Mail is opt-in, and only to an address you have confirmed with a six-digit code.

The directories pass through two same-origin relays because neither federal service sends a CORS header, and what those relays leave out is the telling part. An earlier build listed eight invented clinicians with ratings and “next available” times; npi-proxy.php replaced them with the NPPES register and dropped every field it does not hold — no ratings, no insurance networks, no availability (lines 7–31). For hospitals, cms-proxy.php skips the NPI-2 search, which returns billing entities rather than buildings, and reads the CMS facility file, spelling its filters out in full because the short form is silently ignored and returns all 5,419 rows (lines 6–40).

• What it reads
• NPPES NPI Registry API v2.1, through rxluxury/npi-proxy.php
• CMS Hospital General Information (dataset xubh-q36u), through rxluxury/cms-proxy.php
• OpenStreetMap Nominatim and Overpass, from your browser, for Germany and Panama
• Bundled locally: dicom-parser 1.8.21

What we measured, and when

Our capture (20:13:45 UTC) shows the entry gate, not the desk behind it, so the callouts describe the first screen only. The relays we measured directly. At 20:14:27 UTC we searched Boston clinicians the way a person might type it — “Cardiology”. The relay answered in 0.083 seconds with six rows, every one a pharmacist with a cardiology specialty. At 20:14:35 we used the register’s own term, “Cardiovascular Disease”: 114 rows in 0.097 seconds, each with an NPI number, credential, address and phone. The page’s own picker supplies the register’s terms; a reader typing plain words would be misled.

Boston hospitals, asked at 20:14:27 UTC, took 1.70 seconds: twelve hospitals, each with CMS id, address, county, phone, type, ownership and an emergency-department flag. Six carried a CMS overall rating — Massachusetts General, Brigham and Women’s and New England Baptist at 5, Boston Medical Center and Beth Israel Deaconess at 3, Tufts at 2 — and six had none.

Beside Medicare Care Compare and OHIF Viewer

Each comparator was checked on the date shown. We say what each does better before we say where Rx.Luxury goes further.

Where it falls short

• The hospital relay’s title-casing capitalises the letter after an apostrophe: our Boston answer printed “Brigham And Women’S Hospital” and “Boston Children’S Hospital” (cms-proxy.php line 56).
• Clinician search depends on the register’s wording: “Cardiology” found six pharmacists and no cardiologists.
• No insurance, availability or quality data for clinicians — by design, but Care Compare gives more.
• Outside the US there is only an OpenStreetMap radius search for Germany and Panama, which the code itself calls “a real downgrade from NPPES”.
