64 Hyperbaric Oxygenation Therapy <strong>KCE</strong> Reports 74<br />
5.7.2.1 Description of the Minimal Clinical Data set<br />
The minimal clinical data (in Belgium: Résumé Clinique Minimal/Minimale Klinische<br />
Gegevens, RCM/MKG) is a compulsory registration of information concerning each<br />
hospital stay, whether in classical hospitalization or in one-day clinic. All information is<br />
transferred to the Ministry of Health, where the information is compiled by registration<br />
year. The data are validated internally and compared with reference lists (on the<br />
hospital level and by the Ministry) but the clinical coherency of recorded diagnoses and<br />
procedures are not specifically validated. The <strong>KCE</strong> report on Clinical Quality<br />
Indicators 132 provides more details about biases and flaws linked to MCD analysis.<br />
5.7.2.2 Minimal Clinical Data set and Minimal Financial Data (MFD): methodology for<br />
this study<br />
Relevant ICD-9-CM procedure codes<br />
The following clinical ICD-9-CM procedure codes were selected (ICD-9-CM:<br />
International Classification of Diseases, Ninth Revision, Clinical Modification):<br />
• ICD-9-CM 93.95: “Hyperbaric oxygenation”<br />
• ICD-9-CM 93.97: “Decompression chamber”<br />
Relevant billing codes<br />
The following billing codes from the nomenclature apply:<br />
• 212520: “Installatie van en toezicht op zuurstoftherapie in hyperbare<br />
drukkamer (ongeacht het aantal zittingen): De eerste dag” /<br />
“Installation et surveillance d'une oxygénothérapie en caisson<br />
hyperbare (quel que soit le nombre de séances): Le premier jour”<br />
• 212542: “Installatie van en toezicht op zuurstoftherapie in hyperbare<br />
drukkamer (ongeacht het aantal zittingen): De tweede dag” /<br />
Installation et surveillance d'une oxygénothérapie en caisson hyperbare<br />
(quel que soit le nombre de séances): Le second jour<br />
The codes 212516 and 212531 do no apply for MCD/MFD analysis since these are<br />
ambulatory codes. The code 760642 does not apply since the military hospital is not<br />
registered in the MCD/MFD.<br />
Data selection<br />
The following data were analyzed for the years 2000-2004:<br />
• All coupled stays MCD-MFD<br />
o having ICD-9-CM 93.95 or 93.97 in field in dataset<br />
or<br />
o having 212520 or 212542 in field in<br />
dataset from MFD<br />
• All non-coupled stays from MCD and day stays having ICD-9-CM<br />
93.95 or 93.97 in field in dataset <br />
• The non-coupled stays from MFD having 212520 or 212542 in field<br />
in dataset from MFD, were not<br />
analysed, since for the non-coupled MFD data, there is no diagnosis<br />
available. Neither the Anonymous Day Hospitalization data (available<br />
for 2004-2005) were analyzed for the same reason.<br />
Overview of retrieved MCD-MFD data<br />
In total 3 959 stays were retrieved, of which 3 179 correctly coupled stays, 60<br />
incorrectly coupled stays, 323 non-coupled MCD stays and 397 non-coupled MFD stays.<br />
A full overview of the retrieved data set is provided in appendix.
