Pet therapy in the emergency department and ambulatory care: A systematic review and meta-analysis.

BACKGROUND: Pet therapy, or animal-assisted interventions (AAIs), has demonstrated positive effects for patients, families, and health care providers (HCPs) in inpatient settings. However, the evidence supporting AAIs in emergency or ambulatory care settings is unclear. We conducted a systematic review to evaluate the effectiveness of AAIs on patient, family, and HCP experience in these settings. METHODS: We searched (from inception to May 2020) Medline, Embase, Cochrane CENTRAL, PsycINFO, and CINAHL, plus gray literature, for studies assessing AAIs in emergency and ambulatory care settings on: (1) patient and family anxiety/distress or pain and (2) HCP stress. Screening, data extraction, and quality assessment were done in duplicate with conflicts adjudicated by a third party. Random-effects meta-analyses are reported as mean differences (MDs) or standardized mean differences (SMDs) and 95% confidence intervals (CIs), as appropriate. RESULTS: We included nine randomized controlled trials (RCTs; 341 patients, 146 HCPs, 122 child caregivers), four before-after (83 patients), and one mixed-method study (124 patients). There was no effect across three RCTs measuring patient-reported anxiety/distress (n = 380; SMD = -0.36, 95% CI = -0.95 to 0.23, I2  = 81%), while two before-after studies suggested a benefit (n = 80; SMD = -1.95, 95% CI = -2.99 to -0.91, I2  = 72%). Four RCTs found no difference in measures of observed anxiety/distress (n = 166; SMD = -0.44, 95% CI = -1.01 to 0.13, I2  = 73%) while one before-after study reported a significant benefit (n = 60; SMD = -1.64, 95% CI = -2.23 to -1.05). Three RCTs found no difference in patient-reported pain (n = 202; MD = -0.90, 95% CI = -2.01 to 0.22, I2  = 68%). Two RCTs reported positive but nonsignificant effects on HCP stress. CONCLUSIONS: Limited evidence is available on the effectiveness of AAIs in emergency and ambulatory care settings. Rigorous studies using global experience-oriented (or patient-identified) outcome measures are required.

Body Composition, Strength, and Dietary Intake of Patients with Hip or Knee Osteoarthritis.

PURPOSE: To describe body composition (fat mass (FM) and fat-free mass (FFM)), strength, and nutritional characteristics of patients with hip or knee osteoarthritis undergoing total joint arthroplasty. METHODS: In this prospective pilot study, osteoarthritic patients underwent body composition assessment using bioelectrical impedance analysis, grip strength measurement, and completed a 24-h dietary recall during their pre-operative assessment. RESULTS: Fifty-five patients were included (∼66% females, age 43-89 years). Mean ± SD body mass index (BMI) was 32.79 ± 6.48 kg/m(2) and 62% were obese. Compared with hip osteoarthritis patients, knee osteoarthritis patients had a higher BMI (P = 0.018) and males with knee osteoarthritis had a lower grip strength (P = 0.028). There was a wide range in FM and FFM values across the BMI spectrum. Patients with a higher FM index (FMI, FM/height in m(2)) had higher levels of pain (P = 0.036) and females with higher FMI had a lower grip strength (P = 0.048). Dietary under-reporting was common and many patients did not meet recommendations for protein, vitamins C and E, or omega-3 fatty acids. Those who consumed less protein than the recommended dietary allowance were older (P = 0.018). CONCLUSIONS: A wide variability of body composition and dietary intake was observed which may impact strength and ultimately affect physical function. As such, patients with osteoarthritis may benefit from targeted nutrition and physical activity interventions before and after surgery.
