Purpose:To study survival in two groups of dysphagic patients – one group unable to elicit the pharyngeal stage of swallow (APS) and another group with pharyngeal swallow (WPS) – and to compare recommendations regarding nutrition and therapeutic strategies based on the therapeutic swallowing study.
Material and Methods: In this retrospective study, the records of dysphagic patients who have undergone a therapeutic videoradiographic swallowing study (TVSS) were reviewed. Forty patients without pharyngeal swallow were matched for age and gender with 40 patients with pharyngeal swallow; altogether 80 patients were included in the study. Survival was registered at 3, 12, and 72 months after the TVSS.
Results: In this study, the APS group had a significantly shorter survival time (P = 0.0030) compared to the WPS group when followed‐up at 12 months. In the APS group, most patients (37.5% (15/40)) died within the 3 months after TVSS. At 72 months, 62.5% (25/40) of the patients in the APS group had died. In the WPS group, 5% (2/40) had died within 3 months and 47.4% (19/40) after 12 months. At 72 months, 52.5% (21/40) of the patients in the WPS group had died. Regarding nutritional and therapeutic recommendations based on TVSS, 34/40 in the APS group were recommended no oral intake. Eighteen naso‐gastric tubes were placed directly after TVSS. The therapeutic strategies recommended were head‐positioning, thermal tactile stimulation, and tongue exercises (in 8 patients). In the WPS group, all patients were recommended oral intake. Diet modification was recommended in 29 patients. The therapeutic strategies recommended were head‐positioning, thermal tactile stimulation, tongue exercises, supraglottic swallow, and effortful swallow (in 24 patients).
Conclusion: Patients unable to elicit the pharyngeal stage of swallow had a shorter survival time than patients with pharyngeal swallow, probably due to a more severe underlying disease. Tube feeding was more frequent in the APS group. Fewer therapeutic strategies were recommended compared to the WPS group. In the WPS group, diet modification was frequent. Several patients had different therapeutic strategies. At the end of the study, 8/40 patients (20%) in the APS group had recovered and regained the ability to elicit the pharyngeal stage of swallow. All eight had achieved active swallowing rehabilitation.
