We talk about the importance of psychoeducation for heart patients with Anna Mierzyńska and Karolina Jurczak of the Cardinal Stefan Wyszyński Institute of Cardiology in Anin.
O b j e c t i v e s: Patient-centered care (PCC) is associated with better doctor-patient relationships, resulting in a decrease in symptoms, hospitalizations and health costs. However, studies analyzing factors infl uencing patient-centered attitudes show ambiguous results. The purpose was to assess the impact of the Clinical Communication Course (CCC) in Jagiellonian University, Cracow and other factors on Patient-Centered Attitudes (PCA) and Attitude toward Clinical Skills Learning (CSLA).
M e t h o d s: We retrospectively compared Polish-speakers (CCC+, n = 160), English-speakers (CCCen+, n = 55) aft er the CCC and upperclassmen Polish-speakers without it (CCC–, n = 122). Validated questionnaires to measure PCA (Leeds Attitude Toward Concordance II and Patient-Practitioner Orientation Scale (PPOS)) and for CSLA (Communication Skills Attitude Scale with negative subscale (CSAS-N)) were used. The higher the scores, the more PCA, and negative CSLA respectively. Students completed questionnaires and answered questions regarding age, sex, motivation to study (coded as humanitarian — MotHUM, financial — MotFIN, combination — MotMIX) and considered specialization — coded as with more human contact (family medicine, psychiatry, pediatrics — SpecHUM) and others (SpecNHUM). Statistics were prepared in R.
R e s u l t s: CCC+ scored higher in PPOS (2.91 vs. 2.74; p = 0.003) than CCC– and higher in CSAS-N than CCCen+ (31.22 vs. 28.32; p = 0.004). In CCC+ SpecHUM scored lower than SpecNHUM in PPOS (2.65 vs. 2.94, p = 0.012). MotFIN scored higher then MotMIX in PPOS (3.01 vs. 2.7, p = 0.036). Correlations were statistically significant.
C o n c l u s i o n: CCC improved PCA in CCC+. Th ey showed more negative CSLA than CCCen+. Among CCC+, surprisingly, SpecNHUM presented more PCA than SpecHUM as well as MotFIN compared to MotMIX.
Videoplethysmography is currently recognized as a promising noninvasive heart rate measurement method advantageous for ubiquitous monitoring of humans in natural living conditions. Although the method is considered for application in several areas including telemedicine, sports and assisted living, its dependence on lighting conditions and camera performance is still not investigated enough. In this paper we report on research of various image acquisition aspects including the lighting spectrum, frame rate and compression. In the experimental part, we recorded five video sequences in various lighting conditions (fluorescent artificial light, dim daylight, infrared light, incandescent light bulb) using a programmable frame rate camera and a pulse oximeter as the reference. For a video sequence-based heart rate measurement we implemented a pulse detection algorithm based on the power spectral density, estimated using Welch’s technique. The results showed that lighting conditions and selected video camera settings including compression and the sampling frequency influence the heart rate detection accuracy. The average heart rate error also varies from 0.35 beats per minute (bpm) for fluorescent light to 6.6 bpm for dim daylight.
