While prior studies have focused primarily on diagnostic features, microbiology, and functional outcomes, factors influencing prolonged hospitalization remain insufficiently characterized. Length of stay (LOS) represents a pragmatic, patient- and system-centered outcome that may reflect disease burden and treatment complexity. To identify clinical, demographic, and treatment-related factors associated with prolonged hospitalization in patients treated surgically for septic tenosynovitis of the hand, using LOS \u2265 6 days as a clinically meaningful threshold. Materials and methods: A retrospective cross-sectional study was conducted including 38 adult patients treated surgically for acute septic tenosynovitis of the hand at a tertiary referral center between 1 January 2020 and 31 December 2024. Demographic variables, comorbidities, immunosuppressive status, mechanism of injury, anatomical involvement, time to presentation, microbiological findings, number of surgical procedures, inpatient LOS, and outpatient follow-up visits were analyzed. Results: The mean age was 53.2 \u00b1 15.8 years, and the mean LOS was 7.5 \u00b1 3.7 days (range, 2\u201317 days). Twenty-seven patients (71.1%) experienced an LOS \u2265 6 days. The presence of comorbidities (p = 0.0026) and immunosuppressive status (p = 0.0378) were significantly associated with prolonged hospitalization. In contrast, age, sex, time to presentation, and microbiological culture positivity, were not significantly associated with prolonged LOS. The mean number of outpatient follow-up visits was 2.5 \u00b1 1.9, highlighting an additional post-discharge care burden. Conclusions: Prolonged hospitalization in septic tenosynovitis appears to be driven predominantly by patient-related vulnerability, particularly comorbidities and immunosuppression, rather than by anatomical involvement, microbiological profile, or presentation delay alone. LOS may serve as a useful surrogate marker for treatment burden and resource utilization, supporting early identification of high-risk patients and optimization of inpatient care pathways.<\/jats:p>","DOI":"10.3390\/medicina62030534","type":"journal-article","created":{"date-parts":[[2026,3,13]],"date-time":"2026-03-13T11:12:25Z","timestamp":1773400345000},"page":"534","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Predictors of Prolonged Hospitalization in Pyogenic Tenosynovitis of the Hand: A Retrospective Cohort Study Focused on Length of Stay"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0965-9736","authenticated-orcid":false,"given":"Cristian-Sorin","family":"Hariga","sequence":"first","affiliation":[{"name":"Department 11, Discipline Plastic and Reconstructive Surgery, Bucharest Clinical Emergency Hospital, University of Medicine and Pharmacy Carol Davila, 050474 Bucharest, Romania"},{"name":"Clinic of Plastic Surgery, Aesthetic and Reconstructive Microsurgery, Emergency Clinical Hospital Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9297-6769","authenticated-orcid":false,"given":"Florin-Vlad","family":"Hodea","sequence":"additional","affiliation":[{"name":"Department 11, Discipline Plastic and Reconstructive Surgery, Bucharest Clinical Emergency Hospital, University of Medicine and Pharmacy Carol Davila, 050474 Bucharest, Romania"},{"name":"Clinic of Plastic Surgery, Aesthetic and Reconstructive Microsurgery, Emergency Clinical Hospital Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladut-Alin","family":"Ratoiu","sequence":"additional","affiliation":[{"name":"Clinic of Plastic Surgery, Aesthetic and Reconstructive Microsurgery, Emergency Clinical Hospital Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7205-1134","authenticated-orcid":false,"given":"Eliza-Maria","family":"Bordeanu-Diaconescu","sequence":"additional","affiliation":[{"name":"Clinic of Plastic Surgery, Aesthetic and Reconstructive Microsurgery, Emergency Clinical Hospital Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0033-1219","authenticated-orcid":false,"given":"Madalina-Olivia","family":"Radu-Adamesteanu","sequence":"additional","affiliation":[{"name":"Department 11, Discipline Plastic and Reconstructive Surgery, Bucharest Clinical Emergency Hospital, University of Medicine and Pharmacy Carol Davila, 050474 Bucharest, Romania"},{"name":"Clinic of Plastic Surgery, Aesthetic and Reconstructive Microsurgery, Emergency Clinical Hospital Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Razvan Nicolae","family":"Teodoreanu","sequence":"additional","affiliation":[{"name":"Department 11, Discipline Plastic and Reconstructive Surgery, Bucharest Clinical Emergency Hospital, University of Medicine and Pharmacy Carol Davila, 050474 Bucharest, Romania"},{"name":"Clinic of Plastic Surgery, Aesthetic and Reconstructive Microsurgery, Emergency Clinical Hospital Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristian-Radu","family":"Jecan","sequence":"additional","affiliation":[{"name":"Department 11, Discipline Plastic and Reconstructive Surgery, Bucharest Clinical Emergency Hospital, University of Medicine and Pharmacy Carol Davila, 050474 Bucharest, Romania"},{"name":"Clinic of Plastic Surgery, Aesthetic and Reconstructive Microsurgery, Emergency Clinical Hospital Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2943-2611","authenticated-orcid":false,"given":"Andreea","family":"Grosu-Bularda","sequence":"additional","affiliation":[{"name":"Department 11, Discipline Plastic and Reconstructive Surgery, Bucharest Clinical Emergency Hospital, University of Medicine and Pharmacy Carol Davila, 050474 Bucharest, Romania"},{"name":"Clinic of Plastic Surgery, Aesthetic and Reconstructive Microsurgery, Emergency Clinical Hospital Bucharest, 050474 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"701","DOI":"10.1016\/j.jor.2018.05.030","article-title":"Infectious flexor hand tenosynovitis: State of knowledge.
