{smcl} {* October 25, 2010} {* Version 3.0} help for {hi:icdpic} {hline} {title:Title} {p 4 8 2} {cmd:icdpic} -- International Classification of Diseases Programs for Injury Categorization {title:Version} {p 4 4 2} Version 3.0. {p 4 4 2} ICDPIC Version 3.0 requires STATA 8.0 or higher. ICDPIC Version 3.0 has been tested in STATA 10 and STATA 11, but the authors believe it should also work without incident in STATA 8 and STATA 9. If you have any problems using ICDPIC Version 3.0 in STATA 8 or STATA 9, please inform the authors. {p 4 4 2} ICDPIC Version 3.0 may be installed from within STATA using the {bf:ssc} command. If you installed a previous version of ICDPIC from the SSC archives website using the {bf:ssc} command, we suggest that you first delete it by typing {bf:ssc uninstall icdpic} followed by {bf:ssc install icdpic}. Alternatively, you may use {bf:ssc install icdpic, replace}. See help for {help ssc}. {p 4 4 2} If you installed any previous ICDPIC files obtained directly from the authors, please delete them {bf:ALL} (.ado, .hlp and .dta files) to avoid any conflicts with ICDPIC 3.0 files. {p 4 4 2} Please enter complete variable names in the ICDPIC Version 3.0 dialog boxes. Do not use abbreviations. {p 4 4 2} New to Version 3.0 is the addition of a dialog box (.dlg) file associated with each individual ICDPIC Version 3.0 program (.ado) file. To access the ICDPIC dialog box, and all the ICDPIC programs, type: {cmd:db icdpic}. Typing {cmd:icdpic}, as in earlier versions, will still work, but {bf:ONLY} with {cmd:icdpic}. Forgetting to precede any other individual program name with {bf:db} will produce an error. {p 4 4 2} Fixed in ICDPIC Version 3.0 is the ability to use path\file names containing spaces. {p 4 4 2} Fixed in ICDPIC Version 3.0 is the ability to run in STATA 11.0. {p 4 4 2} Fixed in ICDPIC Version 3.0 is a bug that caused the {bf:triss} program to crash if the {it:rts} variable was named anything other than "rts". {p 4 4 2} New in ICDPIC Version 3.0 ({bf:trauma} program only) is the ability to choose whether an AIS value of 6 automatically forces an ISS of 75 or to automatically have all AIS values of 6 changed to an AIS value of 5 and then have the ISS calculated normally. {p 4 4 2} All dialog boxes in ICDPIC Version 3.0 have memory. Each time a dialog box is opened within the same STATA session, it will remember the values last entered. {p 4 4 2} All dialog boxes in ICDPIC Version 3.0 have the following buttons: {p 6 9 2} {it:OK} executes the program and removes the dialog box from the screen. {p 6 13 2} {it:SUBMIT} executes the program and leaves the dialog box on the screen. Note that if an error message is generated the dialog box may be minimized. {p 6 13 2} {it:CANCEL} removes the dialog box from the screen and does nothing. Clicking on the close icon of the dialog box does the same thing. {p 6 11 2} {it:HELP} leaves the dialog box on the screen and presents the program help file. The {it:HELP} button has a question mark on it. {p 6 11 2} {it:COPY} leaves the dialog box on the screen and copies the program command to the clipboard. {p 6 12 2} {it:RESET} resets the values of the controls in the dialog box to their initial state, just as if the dialog box were invoked for the first time. Each time a user invokes a dialog box, its controls will be filled in with the values the user last entered. {it:RESET} restores the control values to their defaults. The {it:RESET} button has an R on it. {title:Syntax} {p 8 17 2} {cmd:db icdpic} {p 4 4 2} The {it:ICDPIC} dialog box will open. Click on the radio button next to the desired program and then click {it:OK} or {it:Submit}. {title:Description} {p 4 4 2} The {cmd:db icdpic} command presents to the user the master dialog box used to access the International Classification of Diseases Programs for Injury Categorization (IDCPIC). ICDPIC programs, and their associated lookup tables, were developed using Stata (Version 7, StataCorp, College Station TX) for records containing ICD-9-CM codes. We intentionally used an older version of Stata (currently up to Version 11), so that users with older versions could still have access to the programs. The current version (3.0) requires STATA 8.0 or higher. The intention of ICDPIC described here is to provide inexpensive methods for translating International Classification of Diseases (ICD) diagnosis codes into standard injury categories and/or scores. Initial development of these programs occurred as part of research projects funded by the National Center for Injury Prevention and Control through the Harvard Injury Control Research Center (CDC R49/CCR 115279) and by the Maine Medical Center Research Strategic Plan. The authors are grateful for this support and would also appreciate suggestions or corrections from any user of the software. Publications of studies in which these programs or tables are used should cite the authors. We hope ICDPIC will make ICD-9-CM codes easier to use for injury research, and facilitate comparison of categorization methods. Modification of lookup tables could allow easy conversion to ICD-10-CM, and empirically-derived scores (like ICISS) can be updated using newer reference databases. {p 4 4 2} A list of programs to which ICDPIC provides access is found below: {p 4 4 2} {cmd:trauma} provides various classifications and characterizations of trauma based on ICD-9-CM diagnosis codes, specifically codes for Nature of Injury (N-Codes) and External Cause of Injury (E-Codes). {p 4 4 2} {cmd:srr} calculates the survival risk ratio (SRR) and the independent survival risk ratio (SRRi) for all valid ICD-9-CM injury codes (N-Codes) in a data set and stores them in a file on disk. {p 4 4 2} {cmd:iciss} calculates ICISS (ICD-9 based Injury Severity Score) using both survival risk ratios (SRR's) and independent survival risk ratios (SRRl's). {p 4 4 2} {cmd:aps} calculates the anatomic profile score (APS). {p 4 4 2} {cmd:rts} calculates the revised trauma score (RTS). {p 4 4 2} {cmd:triss}, A Trauma and Injury Severity Score (TRISS), estimates patient survival probability. {p 4 4 2} {cmd:ascot}, A Severity Characterization of Trauma (ASCOT), estimates patient survival probability. {p 4 4 2} {cmd:icd9tmpm}, A Trauma Mortality Prediction Model (ICD-9-CM TMPM), ICD-9-CM version. {p 4 4 2} {cmd:ais_tmpm}, A Trauma Mortality Prediction Model (AIS TMPM), AIS version for those with AIS codes only. {p 4 4 2} {cmd:altcharl} determines which Charlson comorbidities are present, the number of Charlson comorbidities present and the Charlson score. {p 4 4 2} {cmd:elixhaus} determines which Elixhauser comorbidities are present and the number of Elixhauser comorbidities present. {p 4 4 2} On a general note, observations in the user's data must be in Stata "wide" format, for example: {bf:ident} {bf:dx1} {bf:dx2} {bf:dx3} 31416 800.1 959.9 E910.9 31417 800.24 410.0 {p 4 4 2} Use the Stata "wide" command (see help for {help reshape}) to obtain this format if the observations are originally recorded in "long" format, for example: {bf:ident} {bf:diagnosis} 31416 800.16 31416 959.9 31416 E910.9 31417 800.24 31417 410.0 {p 4 4 2} For a detailed discussion on each of ICDPIC's programs, their requirements, and options available, the user is directed to each program's individual help file found in the {bf:Also see} section at the end of this help file. It is strongly suggested that the user read each program's help file before running it. {p 4 4 2} Information on the lookup tables provided for use with {cmd:icdpic} can be found in the {bf:Remarks} section below. {title:Options} {p 4 4 2} See individual help files for each program. {title:Remarks} {p 4} {bf:{ul:BACKGROUND}} {p 4 4 2} Administrative databases and registries often describe specific injuries using the International Classification of Diseases (ICD), which has gone from its Eighth Revision through its Tenth Revision over the past few decades. {p 4 4 2} Sacco and colleagues tabulated the observed hospital mortality for patients with each diagnosis code, and assigned each patient an Anatomic Index (AI) equal to the maximum of the observed mortality probabilities for that patient's injury diagnoses. Levy and colleagues similarly tabulated the observed hospital survival for patients with each diagnosis code, and assigned each patient an Estimated Survival Probability (ESP) equal to the product of the observed survival probabilities for that patient's injury diagnoses. A variation of the latter approach, the ICD-9-based Injury Severity Score (ICISS), was popularized years later by Osler and colleagues. {p 4 4 2} The Abbreviated Injury Score (AIS) and Injury Severity Score (ISS) had been previously introduced for clinical studies, and have remained the most popular and most familiar way to describe injury severity, although they were not originally defined in terms of ICD diagnoses. Later, Copes and colleagues described an Anatomic Profile, specified in part by ICD codes, and Osler and colleagues described a New Injury Severity Score (NISS), but these generally failed to displace the AIS or ISS in popular use. {p 4 4 2} More recently, Barell and an international group of colleagues developed a matrix of ICD-9-CM codes to classify injury diagnoses by type and anatomic region; these authors did not relate these categories to severity, although it is possible to do so. Another innovation is the Trauma Mortality Prediction Model, which uses a new approach based on AIS or ICD-9-CM codes as described by Osler et al. {p 4 4 2} Translating ICD codes into AIS codes (and from there to ISS or NISS if desired) was considered with the Eighth Revision of ICD, but only became practical with the increased precision of the ICD Ninth Revision Clinical Modification (ICD-9-CM). A program to make this conversion was further developed with federal grant support at the Johns Hopkins School of Hygiene and Public Health, and was subsequently marketed as ICDMAP-90 by the Tri-Analytics Corporation of Bel Air, Maryland. Since 2001, Tri-Analytics is no longer responsible for this software, although it is still available through Johns Hopkins (according to {browse "http://www.trianalytics.com/pdfs/dataspeak_v8n2.pdf"}). ICDMAP-90 deserves credit for providing a standard method of ICD to AIS conversion for the past two decades. However, it uses proprietary algorithms that are not explicitly stated for the user, and some newer ICD-9-CM codes are not recognized by the program. {p 4 4 2} Anatomic ICD-9-CM diagnosis codes are sometimes called Nature of Injury codes or N-codes. External Cause of Injury codes in ICD-9 (E-codes) refer to the mechanism of injury, such as vehicle crash or gunshot. The CDC has published a suggested categorization of ICD-9 E-codes by mechanism as well as intent. {p 4 4 2} The Revised Trauma Score (RTS) uses physiologic information (not available from ICD-9-CM codes) to predict survival after injury. The Trauma and Injury Severity Score (TRISS) derives a "Probability of Survival" equation from ISS, RTS, and an age indicator variable (equal to 0 for age <= 54 and 1 otherwise). Separate equations have been used for penetrating or blunt injuries. ASCOT is an alternative scale based on the Anatomic Profile, which has generally not been as popular as TRISS. {p 4 4 2} ICD-9-CM codes potentially relating to pre-existing medical conditions may be identified according to the inclusion criteria of Charlson et al, with the "Dartmouth/Manitoba" modifications described by Romano et al. The "Charlson Score" adds weights of 6 for the presence of AIDS or metastatic solid tumor, 3 for severe liver disease, 2 for any malignancy, renal failure, or complications of diabetes, and 1 for other conditions. A more detailed method has been developed by Elixhauser et al but has not been widely used in trauma patients. {p 4} {bf:{ul:LOOKUP TABLES}} {p 4 4 2} Lookup tables are provided for use with the {cmd:trauma}, {cmd:icd9tmpm}, {cmd:ais_tmpm}, {cmd:altcharl}, {cmd:elixhaus} and {cmd:srr} programs. If the user wishes to modify these tables, or provide their own, they must be sorted on the diagnosis code variable (DRG variable for table {bf:drgtab_h.dta}; predot variable for table {bf:mais_s.dta}). All lookup tables are current through September 30, 2008, except for ntab_s1.dta and ntab_s2.dta, which are current through September 30, 2011, barring any late additions and/or corrections. New tables for etab_s1.dta and etab_s2.dta will be provided when a new recommended framework for presenting injury mortality data is issued. {p 4 4 2} The tables for use with the {cmd:trauma} program are: {p 8 12 2} {bf:ntab_s1.dta} (Nature of Injury codes (N-Codes) and their associated data, no decimal point) {p_end} {p 8 12 2} {bf:ntab_s2.dta} (Nature of Injury codes (N-Codes) and their associated data, with decimal point) {p_end} {p 8 12 2} {bf:etab_s1.dta} (External Cause of Injury codes (E-Codes) and their associated data, no decimal point) {p_end} {p 8 12 2} {bf:etab_s2.dta}

and {bf:ntab_s2.dta} were created by analysis of the National Trauma Data Bank (NTDB). The NTDB contains more than 2 million patient records compiled by the American College of Surgeons Committee on Trauma from hundreds of contributing hospitals (see {browse "http://www.facs.org/trauma/ntdb.html"} for further information). ICDPIC does not attempt to assign a specific AIS code for each ICD-9-CM diagnosis code, but only to classify injuries (N-Codes) into a general severity and body region in order to allow for approximate severity scoring. For ICDPIC, we associated each N-Code in the NTDB (Version 6.1) with the ISS body region and AIS severity for the same injury most frequently selected by trauma registrars submitting data to the NTDB. For the few N-Codes that never appeared in association with an AIS code, the authors assigned a body region and AIS score by consensus. N-Codes relating to burn injuries were not coded for AIS severity. Instead, an AIS severity value of 9 (Unknown) was assigned. {p 4 4 2} {bf:ISS Body Regions and AIS Severities not assigned by NTDB usage:} {bf:N-Code} {bf:Body Region} {bf:Severity} 803.83 1 3 803.89
