<![CDATA[Introduction: In 2021, Indonesia was the fifth-largest nation globally regarding the incidence of type 2 diabetes mellitus (T2DM). The quantity of persons diagnosed with T2DM in Indonesia grows each year. Sleep difficulties, sometimes overlooked by individuals with T2DM, are instigated by the symptoms associated with the disorder. This research aims to evaluate the sleep quality of T2DM patients undergoing outpatient treatment at Dr. Soetomo General Academic Hospital during January and February 2024. Methods: Evaluating the characterization of sleep quality in individuals with type 2 diabetes mellitus at the outpatient facility of Dr. Soetomo General Academic Hospital between January-February 2024. The research methodology employed in this investigation is descriptive observational, utilizing a cross-sectional design with the PSQI (Pittsburgh Sleep Quality Index) and MMSE (Mini-Mental State Examination) as instruments for assessing sleep quality in individuals with diabetes mellitus. This research used primary data gathered from guided interviews and secondary data derived from medical records, with inclusion criteria of individuals aged 20-60 years, without cognitive impairment (MMSE score ≥ 24), and exclusion criteria of no prior sleep disorders. Data analysis was conducted in a univariate or descriptive manner. Results: The results from the Pittsburgh Sleep Quality Index (PSQI) survey indicated that a significant portion of participants (63%) suffered from inadequate sleep quality, yielding an average score of 6.31. The elements of sleep quality comprised moderately favourable subjective sleep quality (49%), inadequate sleep latency (81%), and insufficient sleep duration (81%). The majority of participants had high sleep efficiency (94%) yet often encountered sleep disruptions, including nocturnal awakenings (93%) or early morning toilet visits (90%). Moreover, a vast majority abstained from using sleep medications (99%), but 45% indicated encountering daytime impairment 1-2 times weekly. Conclusion: The findings from the PSQI (Pittsburgh Sleep Quality Index) questionnaire indicate that the majority of participants experienced inadequate sleep quality. Consequently, thorough management of patients with type 2 diabetes mellitus is essential in primary care, including the surveillance of problems and the instruction of patients on healthy sleep practices to enhance overall treatment results.]]>
