{"doi":"10.1016/j.xjidi.2023.100186","title":"The Cost Utility of Nonpregnancy Laboratory Monitoring for Persons on Isotretinoin Acne Therapy","abstract":"We sought to project the 1-year cost utility of nonpregnancy laboratory monitoring cessation among patients initiating isotretinoin. We conducted a model-based cost utility analysis comparing (i) current practice (CP) and (ii) cessation of nonpregnancy laboratory monitoring. Simulated 20-year-old persons initiating isotretinoin were maintained on therapy for 6 months, unless taken off because of laboratory abnormalities in CP. Model inputs included probabilities of cell-line abnormalities (0.12%/wk), early cessation of isotretinoin therapy after detection of an abnormal laboratory result (2.2%/wk, CP only), quality-adjusted life-years (0.84-0.93), and laboratory monitory costs ($5/wk). We collected adverse events, deaths, and quality-adjusted life-years and costs (2020 USD) from a health care payer perspective. Over 1 year, and for 200,000 people on isotretinoin in the United States, the CP strategy resulted in 184,730 quality-adjusted life-years (0.9236 per person), and nonpregnancy laboratory monitoring resulted in 184,770 quality-adjusted life-years (0.9238 per person). The CP and nonpregnancy laboratory monitoring strategies resulted in 0.08 and 0.09 isotretinoin-related deaths, respectively. Nonpregnancy laboratory monitoring was the dominating strategy, realizing $24 million savings per year. No variation of a single parameter across its plausible range changed our cost utility findings. Cessation of laboratory monitoring could realize savings of $24 million per year for the US health care system and improve patient outcomes, with negligible effects on adverse events.","journal":"JID Innovations","year":2023,"id":402684,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9527,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":420627,"name":"Shuo Chen","orcid":"0000-0002-0678-7380","position":1,"is_corresponding":false},{"id":594922,"name":"Matilda W.
