Diabetes Mellitus, Type 2
Conditions
Brief summary
To compare the risk of acute pancreatitis in patients with Type 2 diabetes mellitus (T2DM) newly initiating empagliflozin to that of patients newly initiating other oral non-incretin/non-Sodium glucose co-transporter-2 inhibitor (SGLT2i)-containing hypoglycemic agents.
Interventions
empagliflozin

Eligibility
Inclusion criteria
* Patients \>= 18 years old * A diagnosis of Type 2 diabetes mellitus (T2DM) as demonstrated by at least one qualifying diagnosis code from any encounter type recorded in the claims in the 6 months prior to the drug initiation. * Patients initiating empagliflozin (as monotherapy, on a background of metformin, or on a background of metformin and Sulfonylurea (SU)) or qualifying comparator (metformin monotherapy, SU on a background of metformin, or Thiazolidinediones (TZD) on a background of metformin and SU) during the study period. * Have at least 6 months of continuous registration in the database prior to initiation of empagliflozin or a comparator drug.
Exclusion criteria
* Patients with missing or ambiguous age or sex information. * Use of a Sodium glucose co-transporter-2 inhibitor (SGLT2i), Dipeptidyl peptidase 4 inhibitors (DPP-4i) or Glucagon-like peptide-1 receptor agonist (GLP-1 RA) in the 6 months prior to study drug initiation. * Chronic use of insulin in the outpatient setting in the 6 months prior to the study drug initiation. This criterion will help us to remove severe cases of diabetes and reduce the risk of residual confounding as diabetes is a risk factor for developing acute pancreatitis. * Patients with type 1 diabetes mellitus (T1DM) defined as at least 1 inpatient or outpatient International Classification of Diseases Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis code of 250.x1 or 250.x3 or International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis code of E10.x in the 6 months prior to the study drug initiation. * Patients with secondary diabetes or gestational diabetes in the 6 months prior to the study drug initiation. * Claims for acute or chronic pancreatitis, pancreatic cancer, or other disease of the pancreas any time prior to the study drug initiation.

| Incidence Rate of Acute Pancreatitis | From August 2014 to March 2021 (the study period). Up to 79 months. | Incidence rate of acute pancreatitis per number of person-years, defined as an acute pancreatitis diagnosis from any of the inpatient (not restricted to the primary diagnosis), outpatient, or emergency contacts diagnoses (ICD-9-CM 577.0 or ICD-10-CM K85) and a lipase measure within +/- 7 days of the acute pancreatitis diagnosis (using LOINC code of 3040-3 and 2572-6 or CPT code of 83690 for lipase) and an abdominal ultrasound (using CPT codes of 76700 and 76705) within +/- 7 days of the acute pancreatitis diagnosis. The incidence rate was reported as the number of events (counts the first event per patient) divided by the total number of person-years at risk during follow-up (1/(1000\*person-years)). |

Recruitment details
A Post-authorization safety study based on existing data between 1-Aug-2014 and the latest data-cut available in IBM MarketScan (30-Sep-2020) and Optum Clinformatics® Data Mart (CDM) 31-Mar-2021. The study aimed to assess the risk of acute pancreatitis in type 2 diabetes mellitus (T2DM) patients newly initiated in empagliflozin to that of newly initiated in other oral non incretin/non-sodium glucose co-transporter-2 inhibitors (SGLT2i)-based glucose lowering drugs. More details in Limitations.
Pre-assignment details
Every patient who fulfilled inclusion and exclusion criteria was selected until the required sample size was achieved.

Outcome results
Incidence Rate of Acute Pancreatitis
Incidence rate of acute pancreatitis per number of person-years, defined as an acute pancreatitis diagnosis from any of the inpatient (not restricted to the primary diagnosis), outpatient, or emergency contacts diagnoses (ICD-9-CM 577.0 or ICD-10-CM K85) and a lipase measure within +/- 7 days of the acute pancreatitis diagnosis (using LOINC code of 3040-3 and 2572-6 or CPT code of 83690 for lipase) and an abdominal ultrasound (using CPT codes of 76700 and 76705) within +/- 7 days of the acute pancreatitis diagnosis. The incidence rate was reported as the number of events (counts the first event per patient) divided by the total number of person-years at risk during follow-up (1/(1000\*person-years)).
Time frame: From August 2014 to March 2021 (the study period). Up to 79 months.
Population: Pooled unmatched and 1:1 propensity scores (PS) matched cohort of patients with type 2 diabetes mellitus (T2DM) and new initiators of empagliflozin or sulfonylureas (SUs), who were enrolled between 1 August 2014 and the latest data-cut available in IBM MarketScan CCAE/MDCR (30 September 2020) and Optum CDM (31 March 2021). Primary analysis represented an 'as treated' approach.
