Immunosuppressants to Postoperative Infection and Death
Study Details
Study Description
Brief Summary
The goal of this observational study is to explore the different immunosuppressive agents and related outcomes in organ transplantation patients in Taiwan. The main question it aims to answer is the risk of different immunosuppressive agents for infection and survival after transplant.
The study enrolled patients who underwent solid organ transplant (SOT), kidney (ICD-9-CM code V42.0), liver (ICD-9-CM code V42.7), or lung (ICD-9-CM code V42.6) transplants. We employed propensity score matching (PSM) to establish a matched cohort. The study will compare SOT patients and general patients to explore the risk of different immunosuppressive agents for infection and survival.

Detailed Description
This study used secondary data from the Longitudinal Health Insurance Database (LHID), a subset of the NHIRD provided by the Health and Welfare Data Science Center (HWDC) of the Ministry of Health and Welfare in Taiwan.
The HWDC encrypts personally identifying data to protect the privacy of beneficiaries. The database includes detailed clinical records from both the inpatient and outpatient claims of the beneficiaries of Taiwan's National Health Insurance program. This program has provided coverage for up to 99% of the country's population since 1995. The NHIRD can serve as a foundation for the procurement of real-world evidence to support clinical decisions and health-care policy-making.
Diagnostic data within the NHIRD from before 2016 and from 2016 or later are respectively coded using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) and International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes.
The database was provided by the HWDC under license and so cannot be made freely available. Requests for access to these data should be made to HWDC (https://dep.mohw.gov.tw/dos/cp-5119-59201-113.html).

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Patients with organ transplantation Patients who underwent SOTs between 2002 and 2013, specifically, kidney (ICD-9-CM code V42.0), liver (ICD-9-CM code V42.7), or lung (ICD-9-CM code V42.6) transplants. |
Drug: Immunosuppressive Agents
Prescribing immunosuppressive agents

| Patients without organ transplantation The general patients were enrolled as the comparison. We used propensity score matching (PSM) to establish a matched cohort. |

Outcome Measures
Primary Outcome Measures
- Postoperative infection [From the date of underwent SOTs until the date of incident infection or date of death from any cause, whichever came first, assessed up to 5 years.]
Postoperative infection contains Pneumocystis jiroveci pneumonia, cytomegalovirus disease, and Herpes simplex virus
- Death [From the date of underwent SOTs until the date of death from any cause, assessed up to 5 years.]
Death
