A multicomponent intervention to decrease sedentary time during hospitalization: a quasi-experimental pilot study.

OBJECTIVE: The aim of this study was to evaluate the feasibility and preliminary effects of a multicomponent intervention to decrease sedentary time during and shortly after hospitalization. DESIGN: This is a quasi-experimental pilot study comparing outcomes in patients admitted before and after the implementation of the intervention. SETTING: The study was conducted in a university hospital. SUBJECTS: Participants were adult patients undergoing elective organ transplantation or vascular surgery. INTERVENTIONS: In the control phase, patients received usual care, whereas in the intervention phase, patients also received a multicomponent intervention to decrease sedentary time. The intervention comprised eight elements: paper and digital information, an exercise movie, an activity planner, a pedometer and Fitbit Flex™, a personal activity coach and an individualized digital training program. MEASURES: Measures of feasiblity were the self-reported use of the intervention components (yes/no) and satisfaction (low-high = 0-10). Main outcome measure was the median % of sedentary time measured by an accelerometer worn during hospitalization and 7-14 days thereafter. RESULTS: A total of 42 controls (mean age = 59 years, 62% male) and 52 intervention patients (58 years, 52%) were included. The exercise movie, paper information and Fitbit Flex were the three most frequently used components, with highest satisfaction scores for the fitbit, paper information, exercise movie and digital training. Median sedentary time decreased from 99.6% to 95.7% and 99.3% to 91.0% between Days 1 and 6 in patients admitted in the control and intervention phases, respectively. The difference at Day 6 reached statistical significance (difference = 41 min/day, P = 0.01). No differences were seen after discharge. CONCLUSION: Implementing a multicomponent intervention to reduce sedentary time appeared feasible and may be effective during but not directly after hospitalization.

Cognitive problems in patients in a cardiac rehabilitation program after an out-of-hospital cardiac arrest.

OBJECTIVE: Estimate prevalence of cognitive problems due to hypoxic brain injury in out-of-hospital cardiac arrest (OHCA) survivors referred for cardiac rehabilitation and association with quality of life as well as autonomy and participation. DESIGN: Prospective cohort study. METHOD/DESIGN: Consecutive OHCA patients. The Mini-Mental State Examination (MMSE), Cognitive Failures Questionnaire (CFQ) and Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) were administered 4 weeks after the OHCA. Cognitive problems were defined if MMSE <28, CFQ >32 or IQCODE >3.6. The Impact on Participation and Autonomy Questionnaire (IPAQ) (participation/autonomy), the SF-36 Health Survey (SF-36) (quality of life) and the Hospital Anxiety Depression Scale (HADS) (anxiety/depression) were administered. Correlations between cognitive problems and participation/autonomy and quality of life were calculated. RESULTS: 63 of 77 patients were male (82%), median age 59 years (range 15-84). MMSE median 29 (interquartile range 28-30), CFQ mean 20.9 (SD 9.4) and IQCODE mean 3.1 (SD 0.2). Eighteen patients (23%) scored positive for cognitive problems. Significant correlations were found between MMSE and IPAQ: autonomy inside (r = -0.38), family role (r = -0.26), autonomy outside (r = -0.32), social relations (r = -0.38) and social functioning (r = 0.32). MMSE was related to SF-36: social functioning (r = 0.32). The CFQ was related to IPAQ: autonomy outdoors (r = 0.29) and SF-36: bodily pain (r = -0.37), vitality (r = -0.25), mental health (r = -0.35) and role emotional (r = -0.40). The IQCODE was related to IPAQ: autonomy indoors (r = 0.26) and to SF-36: vitality (r = -0.33) and social functioning (r = -0.41). CONCLUSION: Twenty-three percent of the patients referred for cardiac rehabilitation showed cognitive problems. Associations were found between cognitive problems and several aspects of participation/autonomy and perceived quality of life.
