This paper aims to analyze the demographic and prosthodontic treatment differences between patients who did and did not respond to a mailed questionnaire.
All living patients who received tooth- and implant-related fixed prosthodontic treatment between January 1984 and June 2005 (n = 986) in one private prosthodontic practice were mailed a questionnaire regarding their prosthodontic treatment. Demographic data (sex, age) and treatment data (survival, type of treatment, time in situ, number of units, number of treatments) for responding and nonresponding patients were collected from patient files and analyzed. Statistical significance was set at P = .05.
There were 500 responding patients (50.7%) with 2,702 fixed prosthodontic units (60.02%) and 486 nonresponding patients (49.3%) with 1,800 fixed prosthodontic units (39.98%). Prostheses were in situ from 1 to 20 years, with the average time in situ for respondents of 7.47 +/- 5.48 years and 6.5 +/- 5.21 years for nonrespondents. Responding and nonresponding patients had similar sex distributions (P = .61), Kaplan-Meier 10-year estimated cumulative survivals (92.2 +/- 1.72% and 91.5 +/- 1.92%; P = .13), and received a similar distribution of treatment prostheses (implant versus tooth) (P = .24). However, responding patients were significantly older (P < .001), had their prostheses in situ for a greater length of time (P < or = .01), received more prosthetic units (P < .001), and underwent more treatment episodes (P < .001) than nonresponding patients.
Patient questionnaires provide valid and unique research information. Prosthesis outcomes for patients who did and did not respond to the questionnaire were the same. Treatment outcomes of patients who attend review appointments and those who are lost to follow-up cannot be assumed to be different. Demographic- and treatment-related characteristics of responding patients indicated that an enhanced provider-patient rapport was a principal motivator for responding to the questionnaire.
本研究旨在分析接受邮寄问卷调查的患者和未接受问卷调查的患者在人口统计学和修复治疗方面的差异。
1984 年 1 月至 2005 年 6 月期间，一位私人修复医生为所有接受过牙列和种植体相关固定修复治疗的存活患者邮寄了一份调查问卷。从患者病历中收集了回复患者和未回复患者的人口统计学数据（性别、年龄）和治疗数据（存活率、治疗类型、在位时间、单位数、治疗次数）。统计显著性水平设为 P =.05。
共有 500 名回复患者（50.7%），共 2702 个固定修复单位（60.02%），486 名未回复患者（49.3%），共 1800 个固定修复单位（39.98%）。修复体在位时间为 1 至 20 年，回复患者的平均在位时间为 7.47 ± 5.48 年，未回复患者为 6.5 ± 5.21 年。回复患者和未回复患者的性别分布相似（P =.61），10 年Kaplan-Meier 累积生存率估计值（92.2 ± 1.72%和 91.5 ± 1.92%；P =.13）和接受的治疗修复体分布（种植体与天然牙）相似（P =.24）。然而，回复患者的年龄明显更大（P <.001），修复体在位时间更长（P < or =.01），接受的修复单位更多（P <.001），治疗次数更多（P <.001）。
患者问卷提供了有效且独特的研究信息。对问卷调查做出回应和未做出回应的患者的修复体预后相同。参加复诊预约的患者和失访患者的治疗预后不能假定不同。回复患者的人口统计学和治疗相关特征表明，增强医患关系是回复问卷的主要动机。
