Burden incurred by patients and their caregivers after outpatient surgery: a prospective observational study.

INTRODUCTION: The burden of patients and their caregivers after outpatient surgery has not been fully examined. The number of outpatient surgeries has dramatically increased in the last several years, particularly in the orthopaedic sector. Patients undergoing outpatient orthopaedic procedures may be expected to have more postdischarge pain than those undergoing nonorthopaedic outpatient procedures. In light of this, assessment of patient and caregiver expectations and actual burden after discharge is of importance. QUESTIONS/PURPOSES: We assessed the impact of outpatient surgery on recovery of patients and their caregivers in the postoperative period by determining (1) expected versus actual time to resume daily activities, including work; (2) expected versus actual recovery at 7 and 30 days postoperatively; and (3) the number of caregivers that felt emotional or physical disturbances from caring for outpatients. METHODS: Forty-four adult patients undergoing outpatient surgical procedures and their primary caregivers were enrolled in this prospective survey study, of which 30% were orthopaedic patients. Surveys assessing postoperative recovery were given to patients at six time points, on Postoperative Days 0 to 3, 7, and 30. Surveys assessing the burden of informal caregiving were given to each patient's primary caregiver at four time points, on Postoperative Days 1 to 3 and 7. The enrollment rate was 79% (44 enrolled of 56 approached) and the survey response rate was 100% for patients and 93% (41 of 44) for caregivers. RESULTS: We found that 16 of 44 patients (36%) needed more time than originally anticipated to resume their daily activities and three of 29 patients (10%) needed more time off from work than originally anticipated. Patients were approximately 66% and 88% fully recovered 7 and 30 days after surgery, respectively. The primary caregivers noted disturbances in emotional (nine of 43, 21%) and physical (17 of 43, 40%) aspects of their daily lives while providing care for patients. Our surveyed patients were from multiple surgical services; however, our results may be generalized to an orthopaedic population, although they may underestimate actual results for this population given their generally higher pain scores. CONCLUSIONS: Patients may take longer to recover from outpatient surgery than previously recognized. As increased pain and prolonged recovery may be associated with increased caregiver burden, these data are of particular significance to the outpatient orthopaedic surgical population. Informal caregiving after outpatient surgery may be an unrecognized physical and psychologic burden and may have a significant societal impact. LEVEL OF EVIDENCE: Level II, prognostic study.

Prediction of obstructive sleep apnea using visual photographic analysis.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) has been historically underdiagnosed and may be associated with grave perioperative complications. The ASA and American Academy of Sleep Medicine recommend OSA screening prior to surgery; however, only a minority of patients are screened. The objective of this study was to determine the proficiency of anesthesiologists, otolaryngologists, and internists at predicting the presence of OSA by visual photographic analysis without the use of a computer program to assist, and determine if prediction accuracy varies by provider type. DESIGN: Prospective case series SETTING: Tertiary care hospital-based academic center PATIENTS: Fifty-six consecutive patients presenting to the sleep laboratory undergoing polysomnography had frontal and lateral photographs of the face and torso taken. INTERVENTIONS: Not applicable. MEASUREMENTS: Polysomnography outcomes and physician ratings. An obstructive apnea hypopnea index (oAHI) ≥15 was considered "positive." Twenty anesthesiologists, 10 otolaryngologists, and 11 internists viewed patient photographs and scored them as OSA "positive" or "negative" before and after being informed of patient comorbidities. MAIN RESULTS: Nineteen patients had an oAHI <15, 18 were ≥15 but <30, and 19 were ≥30. The mean oAHI was 28.7 ± 26.7 events/h (range, 0-125.7), and the mean body mass index was 34.1 ± 9.7 kg/m(2) (range, 17.4-63.7). Overall, providers predicted the correct answer with 61.8% accuracy without knowledge of comorbidities and 62.6% with knowledge (P < .0001). There was no difference between provider groups (P = .307). Prediction accuracy was unrelated to patient age (P = .067), gender (P = .306), or race (P = .087), but was related to body mass index (P = .0002). CONCLUSION: The ability to predict OSA based on visual inspection of frontal and lateral photographs is marginally superior to chance and did not differ by provider type. Knowledge of comorbidities did not improve prediction accuracy.

Screening for Pediatric Obstructive Sleep Apnea before Ambulatory Surgery.

PURPOSE: The American Society of Anesthesia practice guidelines recommend that pediatric and adult patients who undergo ambulatory surgery be screened for obstructive sleep apnea (OSA). With this in mind, our objective was to assess the frequency of screening by anesthesia providers for the signs and symptoms of OSA in children undergoing surgery in an ambulatory setting. METHODS: Prospective single-blinded observational study of anesthesia providers' preoperative interview of caregivers of consecutive patients younger than age 18 who were scheduled for ambulatory surgery. RESULTS: One hundred one children (30 females) were identified, with a mean age of 6.9 ± 5.0 years; 54 were classified as white, 33 as black, and 14 as other. Total OSA-18 scores ranged from 18 to 97, with a mean of 33.1 ± 14.8. The mean score for adenotonsillectomy patients was higher than that for children who underwent procedures other than adenotonsillectomy. Thirty-one percent of children were screened for OSA, and snoring was the most common symptom recorded (28%). Patients who were screened for OSA were more likely to have snoring (p < 0.001), known OSA (p = 0.006), and a scheduled adenotonsillectomy (p = 0.02). CONCLUSION: OSA was not routinely screened for by anesthesia providers prior to ambulatory pediatric surgery. When screening did occur, "snoring" was the most commonly recorded symptom. Paradoxically, patients with undiagnosed OSA who would benefit the most from screening were the least likely to be screened.

Efficacy of postoperative patient-controlled and continuous infusion epidural analgesia versus intravenous patient-controlled analgesia with opioids: a meta-analysis.

The authors performed a meta-analysis and found that epidural analgesia overall provided superior postoperative analgesia compared with intravenous patient-controlled analgesia. For all types of surgery and pain assessments, all forms of epidural analgesia (both continuous epidural infusion and patient-controlled epidural analgesia) provided significantly superior postoperative analgesia compared with intravenous patient-controlled analgesia, with the exception of hydrophilic opioid-only epidural regimens. Continuous epidural infusion provided statistically significantly superior analgesia versus patient-controlled epidural analgesia for overall pain, pain at rest, and pain with activity; however, patients receiving continuous epidural infusion had a significantly higher incidence of nausea-vomiting and motor block but lower incidence of pruritus. In summary, almost without exception, epidural analgesia, regardless of analgesic agent, epidural regimen, and type and time of pain assessment, provided superior postoperative analgesia compared to intravenous patient-controlled analgesia.
