Abstract

Objective: Identify key demographic factors and modes of follow-up in surgical survey response. Summary Background Data: Surveys are widely used in surgery to assess patient and procedural outcomes, but response rates vary widely which compromises study quality. Currently there is no consensus as to what the average response rate is and which factors are associated with higher response rates. Methods: The National Library of Medicine (MEDLINE/PubMed) was systematically searched from Januray 1, 2007 until February 1, 2020 using the following strategy: (((questionnaire) OR survey) AND “response rate”) AND (surgery OR surgical). Original survey studies from surgical(-related) fields reporting on response rate were included. Through one-way analysis of variance we present mean response rate per survey mode over time, number of additional contacts, country of origin, and type of interviewee. Results: The average response is 70% over 811 studies in patients and 53% over 1746 doctor surveys. In-person surveys yield an average 76% response rate, followed by postal (65%) and online (46% web-based vs 51% email) surveys. Patients respond significantly more often than doctors to surveys by mail (P < 0.001), email (P = 0.003), web-based surveys (P < 0.001) and mixed mode surveys (P = 0.006). Additional contacts significantly improve response rate in email (P = 0.26) and web-based (P = 0.041) surveys in doctors. A wide variation in response rates was identified between countries. Conclusions: Every survey is unique, but the main commonality between studies is response rate. Response rates appear to be highly dependent on type of survey, follow-up, geography, and interviewee type.

Abstract

Objective: This study aimed to evaluate all mesh-related problems during reoperations after mesh-reinforcement 15 years after the start of the PRIMA trial. SUMMARY BACKGROUND DATA Prophylactic mesh reinforcement during closure of a midline laparotomy has proven to reduce the incidence of incisional hernia, especially in high-risk patients, but long-term mesh-related morbidity is largely unknown., Methods: Patients receiving a prophylactic onlay or retro-rectus mesh in the PRIMA trial between 2009 and 2012 were included on an as-treated basis from participating centers that made reoperation notes available. Main outcomes were the incidences of complications requiring mesh explantation, mesh-related ileus, and mesh-related problems during laparotomy for other diagnoses., Methods: Out of 373 patients randomized to prophylactic mesh reinforcement, 242 were included: 127 with onlay and 115 patients with retrorectus mesh. Median follow-up is 27 months (IQR 12-78). Thirty-four patients underwent reoperation for any reason during entire follow-up, 22 after onlay (17.3%) and 12 after retrorectus mesh (10.4%). Reoperation rate for complications that required mesh explantation was 4/127 (3.1%) after onlay and 0/115 (0%) after retrorectus mesh. Mesh-related ileus occurred in none of the onlay group, and 3/115 (2.6%) in the retrorectus group. During subsequent laparotomies for other primary diagnoses, adhesions to the mesh were noted in 3/10 patients in the onlay group and 1/5 patients in the retro-rectus group. Overall, the mesh was removed in 10/127 (7.9%) in the onlay group and 7/115 (6.1%) patients in the retro-rectus group., Conclusions: In high-risk patients receiving a prophylactic mesh during midline laparotomy closure, low incidences of mesh-related complications requiring reoperation and mesh-related problems during unrelated subsequent laparotomies were found, for both the onlay and retrorectus techniques., Competing Interests: Funding statement: The authors report no conflicts of interest. Furthermore, no funding was received from any (non) profit organisation. The authors report no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)
