ABSTRACT
AIM: To assess glaucoma patient satisfaction and follow-up adherence in case management and identify associated predictors to improve healthcare quality and patient outcomes. METHODS: In this cross-sectional study, a total of 119 patients completed a Patient Satisfaction Questionnaire-18 and a sociodemographic questionnaire. Clinical data was obtained from the case management system. Follow-up adherence was defined as completing each follow-up within ±30d of the scheduled time set by ophthalmologists during the study period. RESULTS: Average satisfaction scored 78.65±7, with an average of 4.39±0.58 across the seven dimensions. Age negatively correlated with satisfaction (P=0.008), whilst patients with follow-up duration of 2 or more years reported higher satisfaction (P=0.045). Multivariate logistics regression analysis revealed that longer follow-up durations were associated with lower follow-up adherence (OR=0.97, 95%CI, 0.95-1.00, P=0.044). Additionally, patients with suspected glaucoma (OR=2.72, 95%CI, 1.03-7.20, P=0.044) and those with an annual income over 100 000 Chinese yuan demonstrated higher adherence (OR=5.57, 95%CI, 1.00-30.89, P=0.049). CONCLUSION: The case management model proves effective for glaucoma patients, with positive adherence rates. The implementation of this model can be optimized in the future based on the identified factors and extended to glaucoma patients in more hospitals.
ABSTRACT
The ion channels located on the cell fine structures play an important role in the physiological functions of cell membrane. However, it is impossible to achieve precise positioning on the nanometer scale cellular microstructures by conventional patch-clamp technique, due to the 200 nm resolution limit of optical microscope. To solve this problem, we have established a high-resolution patch-clamp technique, which combined commercial scanning ion conductance microscopy (SICM) and patch-clamp recording through a nanopipette probe, based on SICM feedback control. MDCK cells were used as observation object to test the capability of the technique. Firstly, a feedback controlled SICM nanopipette (approximately 150 MOmega) non-contactly scanned over a selected area of living MDCK cells monolayer to obtain high-resolution topographic images of microvilli and tight-junction microstructures on the MDCK cells monolayer. Secondly, the same nanopipette was non-contactly moved and precisely positioned over the microvilli or tight-junction microstructure under SICM feedback control. Finally, the SICM feedback control was switched off, the nanopipette slowly contacted with the cell membrane to get a patch-clamp giga-ohm sealing in the cell-attached patch-clamp configuration, and then performed ion channel recording as a normal patch-clamp electrode. The ion channel recordings showed that ion channels of microvilli microstructure opened at pipette holding potential of -100, -60, -40, 0, +40, +60, +100 mV (n=11). However, the opening of ion channels of tight-junction microstructure was not detected at pipette holding potential of -100, -40, 0, +40, +100 mV (n=9). These results suggest that our high-resolution patch-clamp technique can achieve accurate nanopipette positioning and nanometer scale high-resolution patch-clamp recording, which may provide a powerful tool to study the spatial distribution and functions of ion channel in the nanometer scale microstructures of living biological samples.
