Background–Inadequate sleep has a negative association with general health and well being.Information about the quantity and quality of sleepin patients in our hospital islacking. A good night’s sleep improves cognitive and emotional functioning, which isimportant during an emotionally challenging stay in the hospital. This study will helpus to explore perceived night time sleep quality and sleep quantity in hospitalizedpatients of General Medicine Department at JSS Hospital and to identify the modifiablefactors associated with sleep disturbances and will help us in introducing remedialmeasures. Methodology: InstitutionalEthicsCommitteeapprovalwasobtained.Totalof110patients(50patients from general wards, 25 patients from ICU complex, 20 patients from threesharing rooms and 15 patients from single rooms) were selected for the study.Samplingmethodchosenforthestudywasprobabilityproportionatetosizesampling. They were explainedregarding thestudy and written informed consentwas taken. The patients wereinterviewed regarding their previous night’ssleepquality and quantity using Verran-Snyder Halpern (VSH) sleep scale. The VSH scaleis a 15 item questionnaire. The VSH scale has three dimensions i.e., sleep disturbance(SD), sleep effectiveness (SE) and sleep supplementation (SS) and were comparedamongstthe four areas. Results-Internal consistency was calculated for each sub scale by the Cronbach’s alpha. Thereliabilitycoefficientalpha(Cronbach'salpha)forVSHSleepdisturbancesubscale was0.941whichissatisfactory.Thereliabilitycoefficientalpha(Cronbach'salpha)for VSH Sleep effectiveness sub scale is 0.807 which is satisfactory. The reliabilitycoefficient alpha (Cronbach's alpha) for VSH Sleep supplementation sub scale is0.651 which is satisfactory. In our study, we found that patients’ sleep were worstaffected in ICU complex (SD mean 465.80 +/- 29.92) and least affected in singlerooms (SD mean 87.33 +/- 22.43). Patients in single room had the most effectivesleep (SE mean 406.00 +/- 13.51) and the least effective sleep in ICU complex (SEmean 204.60 +/- 28.02). The differences in the means of all three dimensions inthese four different areas were statistically significant (p=<0.0001). The Total SleepTime (TST) was highest in single rooms (75.00 +/- 5.98) and least in ICU complex(28.80 +/- 11.93). The Sleep Latency was worst affected in ICU complex (67.40 +/-10.32) and least affected in single rooms (12.00 +/- 4.55). The three most commonfactors that were affecting the patients’ sleep and were statistically significant werelight(66.40%),noise(61.80%)andfrequentstaffinterruptions(47.30%).Fewpatientscomplainedab outthebeddiscomfort(28.20%). Conclusion-Sleep has been affected in hospitalized patients, both in quality and quantity. Sleephas been the most affected in ICU complex and least in single rooms. There is notmuch statistical difference noted between the sleep quality and quantity between thesingle rooms and the three sharing rooms. Patients’ sleep can be improved byreducing the unwanted disturbing noise and lightin the hospital.
