“…The ICPC-3 is interoperable with classifications such as the ICD-10 and ICD-11, the International Classification of Health Interventions (ICHI), 21 and the International Classification of Functioning, Disability and Health (ICF), 22 as well as with clinical terminology classifications such as the Systematized Nomenclature of Medicine -Clinical Terms (SNOMED CT). 23 At the same time, the ICPC-3 remains backward compatible with previous editions of the classification.…”

Improving Primary Health Care Data With ICPC-3: From a Medical to a Person-Centered Perspective

The World Organization of Family Doctors (WONCA) developed the third edition of the International Classification of Primary Care (ICPC-3) to support the shift from a medical perspective to a person-centered perspective in primary health care. The previous editions (ICPC-1 and ICPC-2) allowed description of 3 important elements of health care encounters: the reason for the encounter, the diagnosis and/or health problem, and the process of care. The ICPC-3 adds function-related information as a fourth element, thereby capturing most parts of the encounter in a single practical and concise classification. ICPC-3 thus has the potential to give more insight on patients' activities and functioning, supporting physicians in shifting from a strict medical/disease-based approach to care to a more person-centered approach. The ICPC-3 is also expanded with a new chapter for visits pertaining to immunizations and for coding of special screening examinations and public health promotion; in addition, it contains classes for programs related to reported conditions (eg, a cardiovascular program, a heart failure program) and can accommodate relevant national or regional classes. Classes are selected based on what is truly and frequently occurring in daily practice. Each class has its own codes. Less frequently used concepts pertaining to morbidity are captured as inclusions within the main classes. Implementation of the ICPC-3 in an electronic health record allows provision of meaningful feedback to primary care, and supports the exchange of information within teams and between primary and secondary care. It also gives policy makers and funders insight into what is happening in primary care and thus has the potential to improve provision of care.

“…Despite the evaluation of several international intervention coding and classification systems by healthcare stakeholders in South Africa (public and private), the country is yet to adopt and implement a national intervention classification system. The research aims to establish if the International Classification for Health Interventions (ICHI) [ 3 ] is suitable for coding of interventions rendered to surgical in-patients.…”

Background: The lack of a national intervention coding system and the current intervention coding in South Africa through the use of multiple billing and coding systems does not support quality intervention data collection and patient outcomes reporting for general surgery. This presents difficulties in the understanding of the different types of general surgical interventions performed in hospitals, the associated resources, risks, complications, outcomes reporting, public healthcare delivery, and determination of barriers to care. This study illustrates the use of accurate data on health interventions in South Africa’s acute care general surgery coding to assist in improved resource allocation, using the new WHO International Classification of Health Interventions (ICHI) . ICHI has over 8000 codes and consists of three axes: Target (the entity on which the Action is carried out), Action (a deed performed by an actor to a target), and Means (the processes and methods by which the Action is carried out). A key benefit of ICHI is that it can be used collectively with the International Classification of Diseases (ICD) and the International Classification of Functioning, Disability and Health (ICF). Objectives: to evaluate the suitability of ICHI for general surgery interventions by coding intervention descriptions to ICHI codes; to identify gaps in the ICHI system; and to provide a rationale for ICHI to be a nationally regulated system. Methods: This study adopted a retrospective, descriptive design; in total, 3000 in-patient intervention data files, captured in an electronic database from April 2013 to August 2019 at three academic hospitals in Johannesburg, were extracted randomly, and coded using ICHI. Quantitative data analysis techniques were utilized to assess the overall degree of match between ICHI codes and the intervention descriptions. Results: Of the 3000 patient case entries that were coded, there was an agreement of 67.6% of the coded data amongst the three coders, leaving a variability of 32.4%. The variability was largely due to the coders’ experience and the quality of healthcare documentation. Conclusions: ICHI has the ability to cater for the broad range of general surgery interventions, thus indicating that ICHI is suitable for general surgery coding.

Objective : To evaluate the International Classification of Health Interventions (ICHI) in the clinical and statistical use cases. Materials and Methods : We identified 300 most-performed surgical procedures as represented by their display names in an electronic health record. For comparison with existing coding systems, we coded the procedures in ICHI, SNOMED CT, International Classification of Diseases (ICD)-10-PCS, and CCI (Canadian Classification of Health Interventions), using postcoordination (modification of existing codes by adding other codes), when applicable. Failure analysis was done for cases where full representation was not achieved. The ICHI encoding was further evaluated for adequacy to support statistical reporting by the Organisation for Economic Co-operation and Development (OECD) and European Union (EU) categories of surgical procedures. Results : After deduplication, 229 distinct procedures remained. Without postcoordination, ICHI achieved full representation in 52.8%. A further 19.2% could be fully represented with postcoordination. SNOMED CT was the best performing overall, with 94.3% full representation without postcoordination, and 99.6% with postcoordination. Failure analysis showed that “method” and “target” constituted most of the missing information for ICHI encoding. For all OECD/EU surgical categories, ICHI coding was adequate to support statistical reporting. One OECD/EU category (“Hip replacement, secondary”) required postcoordination for correct assignment. Conclusion : In the clinical use case of capturing information in the electronic health record, ICHI was outperformed by the clinically oriented procedure coding systems (SNOMED CT and CCI), but was comparable to ICD-10-PCS. Postcoordination could be an effective and efficient means of improving coverage. ICHI is generally adequate for the collection of international statistics.
