Changes in quality of life after elective surgery: an observational study comparing two measures.

ABSTRACT: PURPOSE:Our main objective was to compare the change in a validated quality of life measure to a global assessment measure. The secondary objectives were to estimate the minimum clinically important difference (MCID) and to describe the change in quality of life by surgical specialty. METHODS:This prospective cohort study included 7902 adult patients undergoing elective surgery. Changes in the Veterans RAND 12-Item Health Survey (VR-12), composed of a physical component summary (PCS) and a mental component summary (MCS), were calculated using preoperative and postoperative questionnaires. The latter also contained a global assessment question for quality of life. We compared PCS and MCS to the global assessment using descriptive statistics and weighted kappa. MCID was calculated using an anchor-based approach. Analyses were pre-specified and registered (NCT02771964). RESULTS:By the change in VR-12 scores, an equal proportion of patients experienced improvement and deterioration in quality of life (28% for PCS, 25% for MCS). In contrast, by the global assessment measure, 61% reported improvement, while only 10% reported deterioration. Agreement with the global assessment was slight for both PCS (kappa?=?0.20, 57% matched) and MCS (kappa?=?0.10, 54% matched). The MCID for the overall VR-12 score was approximately 2.5 points. Patients undergoing orthopedic surgery showed the most improvement in quality of life measures, while patients undergoing gastrointestinal/hepatobiliary or urologic surgery showed the most deterioration. CONCLUSIONS:Subjective global quality of life report does not agree well with a validated quality of life instrument, perhaps due to patient over-optimism.

Project description:BackgroundMost patients experiencing preoperative anxiety would welcome support in coping with their anxiety. Anxiolytic medication is a common way to address preoperative anxiety. However, the proportion of patients who welcome anxiolytic medication preoperatively and the preferred time of taking it have not been studied thoroughly.MethodsAdult patients (n = 1000) scheduled to undergo elective surgery under general anesthesia were eligible to participate in this single-center observational study. Primary outcomes were the ratio of patients desiring anxiolytic medication (no/yes/on request) and the preferred time of taking it (evening before surgery/morning of day of surgery/on call to the operating room). Secondary outcomes included associations between different measures of anxiety (i.e., anxiety level according to the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and anxiety status (no/yes)) and desire for anxiolytic medication (no/yes/on request). Primary outcomes were analyzed descriptively, and secondary outcomes were analyzed using multinomial logistic regressions.ResultsThree hundred fifty-six (35.6%) out of 1000 patients desired anxiolytic medication and 239 (23.9%) patients would welcome anxiolytic medication on request. In patients reporting anxiety (no/yes; n = 493), 228 (46.2%) stated a clear desire for anxiolytic medication (yes) and 142 (28.8%) considered anxiolytic medication (on request). Patients' preferences concerning the timing of premedication vary widely. In patients reporting a clear desire for anxiolytic medication (n = 356), the "morning of the day of surgery" was most frequently (n = 111, 31.2%) stated as the preferred time to get anxiolytic medication, followed by "on call to the operating room" (n = 51, 14.3%). All anxiety measures were significantly associated with desire for anxiolytic medication (p < 0.05).ConclusionsGiven the importance of preoperative anxiety to patients, patients' desire for anxiolytic medication should be considered when discussing the pros and cons of premedication. Individualized instead of standardized prescription and timing of premedication is recommended.Trial registrationGerman Clinical Trials Register ( DRKS 00013319 , approved 23/11/2017).

Project description:BackgroundPreoperative assessment is crucial to prevent the risk of complications of surgical operations and is usually focused on functional capacity. The increasing availability of wearable devices (smartwatches, trackers, rings, etc) can provide less intrusive assessment methods, reduce costs, and improve accuracy.ObjectiveThe aim of this study was to present and evaluate the possibility of using commercial smartwatch data, such as those retrieved from the Fitbit Inspire 2 device, to assess functional capacity before elective surgery and correlate such data with the current gold standard measure, the 6-Minute Walk Test (6MWT) distance.MethodsDuring the hospital visit, patients were evaluated in terms of functional capacity using the 6MWT. Patients were asked to wear the Fitbit Inspire 2 for 7 days (with flexibility of -2 to +2 days) after the hospital visit, before their surgical operation. Resting heart rate and daily steps data were retrieved directly from the smartwatch. Feature engineering techniques allowed the extraction of heart rate over steps (HROS) and a modified version of Non-Exercise Testing Cardiorespiratory Fitness. All measures were correlated with 6MWT.ResultsIn total, 31 patients were enrolled in the study (n=22, 71% men; n=9, 29% women; mean age 76.06, SD 4.75 years). Data were collected between June 2021 and May 2022. The parameter that correlated best with the 6MWT was the Non-Exercise Testing Cardiorespiratory Fitness index (r=0.68; P<.001). The average resting heart rate over the whole acquisition period for each participant had r=-0.39 (P=.03), even if some patients did not wear the device at night. The correlation of the 6MWT distance with the HROS evaluated at 1% quantile was significant, with Pearson coefficient of -0.39 (P=.04). Fitbit step count had a fair correlation of 0.59 with 6MWT (P<.001).ConclusionsOur study is a promising starting point for the adoption of wearable technology in the evaluation of functional capacity of patients, which was strongly correlated with the gold standard. The study also identified limitations in the availability of metrics, variability of devices, accuracy and quality of data, and accessibility as crucial areas of focus for future studies.
