Special Projects

Socioeconomics Dataset.  The development of a baseline dataset for contrast and comparison with internal analysis of patients and health care operations.  A 540 basic dataset was developed, that can be merged with zip code data.  Data may be used for better understanding local poverty and SES issues possibly linked to health and healthcare. Data include very basic measures like age, gender, and race and ethnicity.  Several ratio, recount and/or regrouping variables were added and then estimates calculated. community-wide race/ethnicity dominance patterns were reviewed and coded into the tables.  Regional, state and census derived values were then added to the dataset.  Other data points include age range groupings and/or counts, zip code area, property size and values, population size, population pyramid age-range datasets, population constitution and diversity data, education history data, schooling, enrollment and unemployment values, employment rates, company/occupational types, annual payroll data, median and average income and other income data, housing, rent, homesize, people per house, per capita income, majority race, school test performance, completed school or college completion data,  school racial majority, food stamp utilization, percent families in severe poverty, unwed child-mother case counts, required health data with rights presented as per 1000 or per 10000 residents, several recommendations for latitude and longitude values (decimal degrees).

Epidemiological Transition Study, by Race, in the H+H 20-25 year EMR Data Warehouse. 17 files.  1.58MB. ~top20 and ~top20NE (no Emergent or EP). Evaluated EMR data for all Diagnoses, linked a particular array of visits, and visits linked to an array of procedures  or health care processes. Primarily CP, IP, VP visit types, perhaps some OP.  No AS, HP. Each patient has ICD (diagnosis) links, to which certain visit types may be linked (focusing on regular visits, and specialty visits, and including/excluding emergent care visits). For each visit, certain semeiological and therapeutic procedures take place, and are related in turn to the ICDs assigned on or linked to that visit.  In theory, the more procedures and visits, the higher the cost for the health care processes engaged in, per ICD per patient, in terms of professional time, equipment used, and billing.  Ratio were used to assess relative patient-ICD-linked stress or demand upon the health care services.  VPR=Visits:Patient Ratio, PVR=Procedures:Visit Ratio (numbers of tests performed per visit, for a given ICD), PPR = Procedures:Patient Ratio (numbers of therapeutic and diagnostic events engaged in per patient, for particular ICD).  VPRs were assessed and then ranked in descending order, per patient group (race-ethnicity groups were the focus, split into Male and Female runs.  The Top 20ICDS by descending VPRs were tabulated, and those tables merged to form a single ranking order descending ICD VPR table, per race-ethnic group.  ICDs were assessed at the integer level, using ICD9.  So subgroups of certain exceptionally high risk ICDs such as tuberculosis, might appear more than once on a table, each value depicting a type of care or level of care related to that ICD. Analyses were performed independently for the time frames 2006-2007, 2011-2012, and 2016-2017.  The most significant changes noted over this 10-12 year time period is the reduction in tuberculosis subtypes, diagnoses linked to joint disease and care, changes in ranks for hepatitis related diagnoses, and possibly cancer related care, involving various organ systems.  Tables produced: Top 20 Diagnoses per Race/Ethnicity Group.  Including, Excluding ED Visits.

The Development of a New Hybrid Risk Score Model. Combining the traditional Charlson, Elixhauser, and Federal Chronic Disease Score Algorithms.  Each of these scoring systems was evaluated.  The three algorithms developed for these runs were then emerged to form a single risk score.  The Federal Chronic Disease (FCD) Score was found to be substantially different from the Elixhauser and Charlson Scoring methods.   FCD is used independently or along with the other two methods for evaluating special patients, especially those involving younger age groups, and focused on Medicaid/CHP patients and families.  The Hybrid (Elixhauser-Charlson) Risk Score algorithm focuses on approximately 30 of the metrics found in these two formulas (Charlson = 12-15 metrics, varying by published version and authors; Elixhauser = 35-40, depending upon measurability as defined by EMR format and content).

Kardex Codes.  Institutional level of care coding invented by Yale researchers in the 1970s; focus was on nursing skills; applied to entire health care system in just a few years. Originally 83 categories were categorized.  There are about 25 standard categories, 10 very common but not standard categories, and one or three additional levels of relationships, such as events/notes related to legal issue, post-op, psychiatry, mental health, social services, group therapy, intervention nursing, specific disease types (esp. Diabetes), L&D, operative and post-op care, home nursing, respiratory therapy, PT, basic drug/pharma inventory, in-house pharmacy, special pharmacy, electronic prescription tools generated order, care,  trimmed to 73 since origination; varies between facilities, with some facility specific or unique service related coding. 11 folders. 170 files.  465 MB. [2016-2022]

Religion Codes.  Approximate 65 religions were found entered into EMR.  Many were misspelled, truncated, abbreviated, or alternatively spelled.  Many were based upon common classification terms not normally associated with religious names.  These names were reclassified new sets, several times, until approximately 20, 15 and 12 major classes could be defined.  Due to rarity of some classes, these classes were classified into new groupings, for use as a generic “Other” in subsequent analyses.  Factors considered when regrouping these religions include cultural, philosophical, metaphysical histories and known or documented lifestyle practices related to: belief in a “creator” or the like, variations on the “creator” definition and theme, continental and/or large geographic or cultural background and practices (i.e. varying Asians), basic Christian, Judaic, versus Muslim belief bases, unique spiritualist/spirit leader derivations, shared energy based interpretations of the universe, the body and health, shared foodways or eating habits (vegan to carnivore), shared holiday or calendar patterns, shared lifestyle and sleeping patterns, etc.

This algorithm takes 20 to 30 minutes to run on the national data.  Semi-automated/semi-manually, this process produces 20 videos per day, 15sec to 4 mins/video (avg 45-60sec),  at 400-2000 images per video, averaging 20,000 images per day, with a 1:3 ratio of run:production/view time.   Automating the last process triples productivity, to 60 videos/day, 60,000 images/day.  I demonstrated to several potential vendors that when fully automated (running in the background in a good Teradata system), it is capable of doubling to quadrupling productivity, more if you apply it into the evening.  Production rates calculated per person over the past several years have been:  100,000 images per week (100 videos), more than 5 million images (5000 1minute videos) per year, for the semi-automated processing technique. Reporting for each single metric, without the video, requires one tenth the time or less!  A daily surveillance report of hundreds of potential in-migrating foreign born diseases can be accomplished using this technique, within a standard public IT work setting.
